Teardown of a hot air coat hanger for drying clothes.
HTML-код
- Опубликовано: 18 июн 2019
- Someone suggested I got one of these to take to bits, so here it is. It's a coat hanger that has a fan heater built in to allow individual lightweight garments to be dried. I think the idea is that it's compact enough for travel and allows convenient low volume laundry while travelling.
I'm not sure how this would fare with a heavy sweatshirt. I think it's more for lightweight items that don't hold a lot of moisture.
The construction is pretty good. It's still a plastic heater though, which never fully inspires confidence. That said, it has two safety layers in the form of self regulating PTC elements and what appears to be a thermal fuse or cutout. The power rating is also pretty low at around 130W.
The internal design suggests that the designer is a veteran of the industry. It's got a lot of clever features to allow fast assembly, and reassembling it after the teardown was surprisingly easy.
Quality control does appear to be lacking though, as the hook was very obviously mis-moulded meaning that the unit can't be hooked up securely in use, which is a big issue for something that heats up and could end up being covered by the garment it was supposed to be drying.

"The Flickerin' Hopi from the Isle of Man" sounds like a character from a Neil Gaiman story
Stan Dudinski it’s only flickering because of the shutter speed of the camera I think
@@hunterton4310 it's also greatly due to the frequency the display 'flickers', Some bulbs flicker as badly as the Hopi as well.
Seemed like a good opportunity to use your thermal imaging camera (hang damp shirt on the hanger, leave it on for a couple of minutes, then look at how uniform the temperature is.
This thing is great for when you get the cold shoulder
Then you put the boot in.
It's a bad shirt incinerator!
A "Bung for your Bottom Outlet" - Demonitized.
This actually looks like a good thing to have at home, and the build quality isn't shoddy either. Plus the price is quite reasonable. I like it.
Considering the rest of the product looks fairly well made, I'm surprised that the short moulded plastic hook got past at least two stages of quality control /inspection . As an ex injection moulding machine setter/ operator, this was probably made during the first few machine start up cycles or maybe the material feed ran out but was missed by the operator, also the assembly line & the packing department!
For a coat hanger, the hook is the most essential part of the item!!
Thats why the deep discount pricing on EBay
A Chinese qc sticker isn't worth the printed sticker its stuck on.
Or in this case the ink used to stamp.
That thermal cut-out/switch thing is in fact a thermostat - that's what they're sold as, anyway. That particular type is known as the "KSD9700" and it's all over AliExpress (and probably eBay as well). They're available in temperature thresholds between 15-155℃, with both NO and NC types, and are (supposedly) rated either 5A or 10A at 250V. This particular listing has them for between £0.81-2.10 for 5pcs, plus £1.10 shipping. I suspect it's just a bimetallic switch - certainly you can hear a distinct "click!" every time it turns on or off.
I've used a couple of them to add two-stage temperature-regulated fan control to a cheap (£40) 24V/25A (600W) power supply that was supplied with an always-on fan, and that works quite nicely. I don't recall the exact temperature thresholds I used, but I use one of those devices to turn the fan on at around 40-50℃, but initially through a resistor (one of the speed reducer cables that are supplied with higher-end PC fans), and then at around 70℃ it bypasses the resistor to run it at full speed. That PSU is the main supply for my 3D printer and its LED-lit enclosure, so most of the time it's outputting only ~2A to drive the LEDs and the printer's motherboard in standby mode, and having the fan running at full speed for such a low load was pretty annoying!
That does make sense, since the risk of this device getting covered with clothing in use is high, and a one-shot thermal fuse would be annoying.
Hey Clive: The converter IC you were looking for is the MPS MP157. Not a dirt cheap part, really.
Get well soon Clive. Thanks for sharing despite the cold/flu. Remember to take care of yourself though.
This is the kind of thing thats just designed well. Its nice to see among many cheap novice crap.
Oh my. I need to buy this immediately.
I'm a hockey player and often have padded gear and skates that are drenched in sweat. The branded versions of this sort of thing are extremely expensive. This thing seems much more reasonable.
Faiz Imam Know your feels, need to get one. When padding is soaked in sweat it takes hours to dry. That little thing might do the trick nicely!
Thanks for the tear down Big Clive. I hope you feel better soon.
A heated coat hanger? Who in their right mind woke up one morning and said "you know... If we only had a heated coat hanger? - Hold my coffee!!!"
lmao, was thinking the same!
The same people who made a power meter named after an indian tribe (the Hopi).
This is more reminiscent of something from IKEA than a cheap Chinese product. A lot of care put into layout and function. IKEA would probably have a thicker, more stubborn plastic casing.
Wim Widdershins if Ikea sold it it would work out much more expensive. Not because the product itself would cost more, just because it's impossible to go to IKEA and not come home with £40 worth of bloody candles.
if it weren't for candles...
If this ever was to be sold by Ikea, it would probibly have a $60.00 price tag, not a $12.00 one.
I like these videos where Clive doesn't get stuck on the technical aspects (which are great too) but also comments more about the safety, longevity and cleverness of the device, like a mix between Teardown and Review.
Not a bad idea, this gadget. I don't travel enough to say whether it'd be useful to me, but I can see the appeal. Thanks for the teardown, Clive, and PLEASE feel better soon!
I really enjoyed this teardown. It looks like a clever little product.
I have seen lots of ads on social media for some "gallium nitride" deathdapter-USB charger thing, you should find one of them to tear down...
Who is it made by?
@@techfreak244 i don't remember, I hadn't given it much thought until Clive was talking about how some deathdapters are better than others
@@matthewmiller6068 like anker
Anker & others
Caveat: this is not a particularly good article, imo, but here it is:
appleinsider.com/articles/19/06/21/gallium-nitride-chargers-what-are-they-and-why-theyre-great
this is cool you liked my suggestion for a tear-down
Does it work? How long to dry a mildly damp shirt?
Great dissection, and reverse engineering Clive. Excellent macro photography, impressive depth.
Thanks for sharing and best regards from the Black Country.
Liked & I've been subscribed for years!
Clive, at times like this I'd love to watch the reassembly of the items you take apart. I'm sure there's a chance to explain more about the safety design, longevity & quality of the items that's missing at the end of your videos.
Either way, j love your channel dearly. Especially the tales from your previous jobs. The one about the xmas lights for instance. Sadly, the tea urn incident fit straight into my opinion of the dibble. Dirty cop takes on a whole new meaning!
Bugger, side tracked again.
I'm an Aspie & feel very "at home" on your channel Clive, thank you!
And get well soon 😋✌️
I've been watching you and I think I'm finally beginning to understand this all. Just a little bit, but it's all coming together. Thanks for the knowledge, it's a fun trip :)
The extreme zoom makes following your dissection SO much easier to follow.
Thank you.
I am always looking forward to the next installment. Nothing but thumbs ups!
Clive in my experience those metal ones are one and done's, no reset. Learned that the hard way when i tried to heat shrink it on :P
That is surprisingly well-made. Might get one...
I bought some of those "thermal fuse" or "thermal cutout" a while back off Ebay. It's a bimetal switch under the heading of
Bimetal Temperature Control Switch Thermostat
I have shoe and glove dryer that is also a timer, heating element, fan and some plastic air channels. Mine is so old that it uses a nichrome wire for the heating element, a mechanical timer, and a slide switch that turns the heater off or on.
It is very useful for drying shoes and gloves.
Dry a coat and it goes wrong you've got a blazer !
Called a "short shot" when plastic part isn't fully moulded.
Yup!
Cheesium manufacturing aside, some of the design ideas on this are actually pretty good... not sure I'd have a use for such a device though. I just turn my shoes upside-down on a heater vent in the house and turn the fan on and they dry in reasonable time. Maybe if I traveled a lot more than I do for business this might be useful, but I don't do that anymore. Problem is, the origin of the devices manufacture would leave me uneasy about leaving this thing unattended and trusting it not to burn the hotel down.
I got butter in my toaster once, I used a death adapter to prevent it tripping the earth by plugging it in with the earth hanging out the other side. I didn't touch the toaster, I just let it burn off the butter and it seemed to fix the tripping problem.
Great video and breakdown Clive
Here! The Hopi has that same dodgy style socket too. I didn't notice till you had them together.
Always good to see a quality deathdaptor.
The boot dryer is pretty nice down here in Florida's summers. If your boots aren't soaked with sweat, they're soaked with rain and sweat too.
I LIKE WATCHING YOUR CHANNEL ALL THE TIME
I always wanted to make one of these for drying my work boots.
unfortunately it'll blow a lot of air that smells like the inside of your moist work boots into your house.
stuffing boots with scrunched up newspaper overnight works pretty well though
@@joinedupjon I got a mudroom.
I also planned on putting an ozone ionizer device in it.
Get Better Big Guy.
Thanks for the upload
Connecting the ground of an appliance to power is always a lot of fun especially if your Appliance is metal and you touch that Appliance and one that is properly grounded at the same time.
"It's quite nicely made!" Big Clive just boosted the audience for this particular device twofold. ;)
Very interesting presentation, the pictures that you show are really fantastic in resolution.. in one of your videos you should show how you take the pictures and what you have to do to get the end product that we see . Your presentations are always interesting and informative
neat product! hope they come out with a rechargeable/cordless version.
At least your deathdapters have insulated pins! The ones they send to Australia don't even have those.
And that’s not all! Now, you can smoke salmon, sun dry tomatoes, and dry your Hugo Boss shirt with this amazing invention!
Looks like a Northrop flying wing. Nice airfoil, too. ... cool
this looks like a good idea to preheat a winter coat. and boots.
@2:30 the bad injection moulding is referred to as a “short shot”
I had to translate "trainers" from UK to USA English LOL. Love your videos.
Steve D Yeah a bit sneaky that one.
hi clive i just saw an advert for a mini air conditioning machine for your clothes from a company tajima i believe it is that would be a cool review to see pun intended keep up the good work sir
Hope you get to feeling better Buddy!
Get well soonClive, you sound rough my friend, :-( well done for getting through the teardown, i know its crap, been there, but your brain just carries on lol... great vid. not a bad design to be fair too...
The quality of the circuit photo I actually thought you had your hand on a massive capacitor for a while 😂
Clive you have a 3D printer so print yourself a new Hook ;) Good looking product too on my watch list to grab one at some stage.

Designing the piece in 3D from scratch and printing such a complex shape which is not optimized for 3D printing is quite a chalenge. First give it a 1-3 days designing the piece assuming he has experience in that, and then printing it is the easy part, the hard part is the tolerances and support material and cleaning it once printed. Its not all "just 3D print a spare part", and also considering the use case he would have to print it in a heat resistant material, say petg or abs depending on the temperature of the thing.
@@laharl2k Seriously 1-3 days - YOU need to practice more if it takes you that long. That part laid out as a flat question mark would print fine for strength given the layers. There would be minimal heat radiated up given the airflow and fan but ABS would be nicer. Not much of a challenge but a 'real world' use case to try his 3D printer!
How do you know he has a 3d printer?
@@zeiphon ruclips.net/video/E4EoTkigmLw/видео.html It needs more use ;)
Wow thermal cut out didn’t expect that it actually sounds safe
Pre-fluffed, steady Clive.
Hey Clive... Have you ever made one of those persistence of vision LED whirly things? Something to do for one of your video projects uploads, perhaps... :)
The shoe accessories would be great for making your own lightsabre.
I WATCH YOUR CHANNEL ALL THE TIME NOW ITS 😎
this reminds me of when I tore apart a broken "entertainment projector" and found a separate driver is what I can assume to power the 12 volt 50 watt halogen lamp in it.
I assume that with the shoedapters you also get a gas mask. Or at least some air freshener. Blowing hot air through shoes is likely to result in some nasty odours.
I feel like it's intended for wet shoes
@@sylashullett428
And that makes it better? I doubt it. You'll get moist *smelly* air permeating the room.
gas mask is recommended, shoes smell nasty 😨 What about UVc and/ or ozone shoesdapters ?
@@ElectroXa
Ah, Clive did mention an ionizer option. Maybe that's what it's for. If it produces enough ozone as a by-product. Then you can rot your clothing from the inside.
Yay the hopi meter!
I just use a 12in desk fan at low speed and a clothes rack. Everything is dry after maybe 4-5 hours. No heat required - only needs airflow. Can take a few hours longer at lower temperatures though.
Same. If you add a bit of heat though it does speed it up a lot, doesn't even need to be much. Sunny window, radiator...
Also be careful to ventilate, we have had some nasty surprises with mildew.
Must have accessory for any fursuiter. I made my own by ductaping 2 big 3d printed fans to a hanger. It blows hard :p
Wish I had one (or two) of these when I was over in your neck of the woods, It's a bugger to get clothes dry in hotel rooms.
Hope you feel better soon
Something New “ The Exploded View a life”👍
Thanks Clive. Very neat, apart from it being useless, because of the faulty moulding of the hook. Chocolate fireguards come to mind, for some reason.
What peak temperature is reached within the clothing/shoes, please? That could be an area of concern.
Wow, you actually sound Ill in this one.. Be well my Clive.
Hello Clive, I appreciate your videos. They are very informative and educational. Could you do a video on LED inverters and/or LED emergency lights (lyfelite)? Thank you
I've made a few videos about the "intelligent" LED emergency lamps.
Why would you travel somewhere cold and damp?
It's for when you travel somewhere sunny and end up moist.
I always wanted a Portable Electric Folding Clothes Hanger Dryer Drying Rack Travel Laundry Rack !
Now I know where to get a Portable Electric Folding Clothes Hanger Dryer Drying Rack Travel Laundry Rack from.
This would totally never set your clothing and/or closet and/or home on fire.
I'm just wondering, should I get one of these instead of using my ceiling fan and a coat hanger! Or as I sometimes do in Winter, instead of using my air-conditioner, though the air-con does actually dry the air, so is beneficial.
in winter time you may want to find a warm cloth to put on when you get up from the bed
you could connect to a timer I guess...
Gave up on Aliexpress. First few orders went through fine. Then the next few just didn't arrive, pain in the neck doing the claims procedure. Gone back to Banggood, out of about 50 orders only had an issue with two, both due to damage, and they were replaced very quickly. OK you pay a little more, and they don't have as wide a range of products.
That heating element is whats usually in small space heaters that use that style.
Large space heaters rely on hydrogen fusion.
Man Clive , you sound a bit sick in this video....but its still a great video, and a surprisingly useful product for a change (except for the hanger) I believe that it says on the PCB Ion, which proves your point on some models of this came with a Ionizer
Very neet heater clive
All the sudden my favorite shirt bursts into flames on its hanger
Hope you feel Well Again Soon Clife
voice smoother than a friction-less surface
Shame clive hope you feel better soon but lov your vids never give up ,.//.,
I was looking for something like this to dry my motorbike gear after travelling in inclement weather. Then I remembered that I own a dehumidifier with ozone option, a few bulldog clips to seal up the neck, wrist holes and I am confident that I have a wiener!!!!
You live in the isle of mann? Cool man! Just assumed you lived in scotland
He said bung. Feel better BigClive.
A bung for the bottom outlet no less!
Do I detect the sounds of a Man Still Battling the Creeping Crud ? Double Whisky and a Hot Bath Ends that crap. The Whisky coupled with the Elevated Body Temps burns that stuff out of you Sir ! The Endless Dissection of Weird Chinesium Gadgets. LOL I've came across those heating elements a few times and wasn't sure how they worked. Afraid to just plug on in. LOL
Very handy for soggy cycling shoes, cheaper than a pair of waterproof socks.
Heh, all the way into it I was shouting "Shoes? What about the bottom slit!" Then you found the bung. So yeah, good design... in the end 🙂
I had one of those "deathdapters" once, came free with something. It went in the bin.
theres driers for trainers/boots that have tubes vertical with heaters at the botom of each no fans typically and the heat just moves up through your upside down boots. best way ive found.
The Peet boot dryer. That version isn't sold in the UK.
@@bigclivedotcomah ok, I assumed you've seen it. well if you ever really want something that you can't get over there I'm sure someone in the u.s. following your channel wouldn't mind helping getting it to you...😉
Nice! I've seen these used to help dry out fursuits. They're more gentle than a clothes dryer.
Interesting short on that injection molded hook. Those types of defects are usually pretty easy to spot and fix. I'm really curious about the story behind this. Maybe one of the cavities was starting to fail, and they didn't want to bother disabling cavities (making the machine produce parts slower) and/or qc thought is was "good enough" (parts customer must have not been too picky). Either that, or the machine operator was new and didn't know what they were doing.
F...fursuits D:
Or these are factory defect units being sold off cheap.
Keep up the excellent legal work, miles...;)
@@bdf2718 Maybe - If those hooks were also used for another product, that would make some sense. However, if they were custom molds designed for that, then why would assembly use a bad hook? It looks like the rest of the product is perfectly fine.
There are a bunch of other plastic parts that are clearly not generic, so there was some money spent tooling that. My bet is that those hooks were custom tooled anyways.
Chinese business culture is obviously different (and I'm not familiar with) - which may have allowed for lower quality standards.
@@milestailprower
Why would they use a bad hook? Because, largely, the workers don't have a clue what they're doing and are told not to question.
The machine produces bad hooks? Not the operator's job to question. Company has no QA so they get shipped. And if somebody notices they get shipped anyway in the hope they won't get returned.
Guy on the assembly line gets bad hooks? Not his job to question. Maybe there was a design change. Probably he has no idea what the thing is meant to do or how it's meant to operate. It gets assembled anyway.
Producer doesn't notice or doesn't care about the problem, or sells the defective assembled products for parts. Probably knows they'll be snapped up by some eBay merchant happy to sell them on cheap.
It makes no sense that a product with a lot of custom tooling for well-designed parts would have such a crappy hook designed in. But it does make sense that people would see what they could get away with if they ended up with some defective parts.
It came with a death-dapter, which is one of the crappier ones. *proceeds to show another deathdapter with charring from a neat little fault*
Interesting contraption
I have a request. It's a little different so you may not want to cover it but it's not terribly far out there. I'm interested in modifying laptop PSUs for different voltages. I have a bunch in the 17V range but I need something in 13.5. I know they're typically controlled with a feedback loop. Something you'd care to look at?
Public liability, you would have to be mad to have anything to do with that.
@@FarleyHillBilly I'm sure it's possible to cover it in a way that avoids liability. Clive has covered voltage regulation before.
Why not use a cheap buck converter?
Hope you are feeling better.
Quite a high component count for a simple fan and heater.
It'snot too bad. The bulk of the components are for the power supply that derives a 12V supply for the fan from the incoming supply.
I too am supplied pre-fluffed.
But will it melt into a blob of aluminum when the switch fails?
A bung for your bottom outlet?!? ;)
Please tell me what to avoid in a adaptor please
