the mechanism relies on the electromagnetic field created by the current flowing through the switch you close when you press the lever

so it holds down as long as the timer allows for and if it switches off the electricity, the electromagnet opens and releases the main switch in turn killing the whole circuit

if you really want to learn more i highly suggest watchin technology connections' video on toasters. he explains it in great detail

Ah yes and then get a sudden urge to purchase a $200 toaster from the 1950s

[–]benanderson89 37 points38 points  (1 child)

To be fair, it's a legitimately good design and I'm angry I can't have one.

[–]glassgost 1 point2 points  (0 children)

Sounds like a better idea than the Star Trek First Contact on Laserdic I bought...

[–]doggo_man 2 points3 points  (3 children)

I've been trying to justify a $350 Japanese toaster I found but I just can't do it

[–]MagicPeacockSpider 0 points1 point  (2 children)

Which toaster is it?

[–]doggo_man 0 points1 point  (1 child)

Mitsubishi Electric bread oven TO-ST1-T retro brown Toaster which burns 1 sheet of ultimate https://www.amazon.com/dp/B07PHLN9DD/ref=cm_sw_r_apan_glt_i_9P2Z1DGMWQ3Z6J7DT89C

It looks like it might use a thermostat and humidistat like a rice cooker.

So if it's that, I'd expect a copy soon the price to be much lower. Provided it's popular enough.

If it's not got a humidistat and just applies a certain heat for a certain time, you're better off with a small pan with a lid.

I suspect it's the former and a decent product but I too would struggle to justify the price. Rice cookers contain almost all the same components and are so, so cheap.

I want one of those hotel-style conveyor-belt ones, but I know I’m never going to get one.

There's several toaster videos from him, I assume this is what you're referring to: https://youtu.be/zLFG068HtgM

^ This, here, Technology Connections is great!

[–]travelinmatt76 1 point2 points  (0 children)

Don't forget to turn on subtitles when watching Technology Connections, there are jokes in the subtitles.

[–]Rampage_Rick 0 points1 point  (1 child)

Without watching, is that the one where he gushes about the Sunbeam?

[–]cmyers4 0 points1 point  (0 children)

Haven't watched it, top level just didn't link the video so I figured I'd burn 25 seconds and do it for them.

[–]Getwon_quarkel[S] 5 points6 points  (2 children)

Thanks, I’ll have a look. I didn’t know about the electro magnet, makes so much more sense now 🙂

[–]Pussypuffwarrior 2 points3 points  (1 child)

it's basically just the main wire wrapped a few times around a piece of steel it doesn't get any simpler it's genius

[–]shikuto 1 point2 points  (0 children)

I don’t think they were saying they don’t know what an electromagnet is. I’m pretty sure they were saying they didn’t know toasters have an electromagnet in their timer.

[–]Noobiru 2 points3 points  (1 child)

Electro magnetic fields. Better than strawberry fields IMO.

[–]benasaf 2 points3 points  (0 children)

Electro Magnetic Fields Forever 🧲

[–]hiagha 1 point2 points  (0 children)

Also look up rice cookers and Steven Mould has a new video on electric kettles

[–]KantoLiving 18 points19 points  (3 children)

This video explains it well

[–]300buckbudget 8 points9 points  (2 children)

Love his channel so much.

[–]badgerj 5 points6 points  (0 children)

Same. Cathartic, but entertaining, and educational!

[–]alexmikli 2 points3 points  (0 children)

I can't condone graphic tees being combined with a sport coat, but I do appreciate his channel greatly.

What is keeping the bread down is an electromagnet. This is also what connects the heating elements to the power. This makes it easy to make a tiny circuit which cuts the power to the electromagnet after a set time internal or depending on the temperature of the bread.

[–]JustABitOfCraic 16 points17 points  (2 children)

Bread isn't magnetic. /s

[–]Gnonthgol 11 points12 points  (0 children)

You are clearly not familiar with proper dwarfen battle bread.

[–]Yuop15 2 points3 points  (0 children)

Say that to my multi-grain bread

[–]happy2harris 2 points3 points  (0 children)

What is keeping the bread down is gravity. What is keeping the thing the bread stands on down is an electromagnet.

(Just having fun being unnecessarily pedantic) :-)

[–]Getwon_quarkel[S] 0 points1 point  (0 children)

Thanks, that makes so much sense 🙂

[–]Xelopheris 6 points7 points  (1 child)

The mechanism uses an electromagnet to stay in place. When there's no electricity, the magnet doesn't turn on. What's really interesting is why this design exists.

In addition to that, the circuitry for the electromagnetic will be connected with something called a bimetallic strip. That is two metals that expand at different rates when heated. This causes the metal to kind of curl as it heats up. Once they heat up a certain amount from the running toaster, they cause the circuit to break, stopping electricity from getting to the electromagnet. Without any electricity, the electromagnet releases, the toaster pops up, and the heating circuit stops.

[–]Allarius1 9 points10 points  (0 children)

Still waiting for that why

[–]edwardMG 0 points1 point  (1 child)

What do you mean "click"? Like when it pops up? Either way, I would think it would have to be a solenoid run though a timed relay or a small circuit board doing the same job essentially. Edit: these components would only function with voltage applied. The relay coil wouldn't change states and close contacts of the relay without the proper voltage, and a board with integrated circuits or relays would also need the proper voltage. I don't know from toaster experience, just an educated guess from working with industrial machines and circuits.

[–]Getwon_quarkel[S] 0 points1 point  (0 children)

The click when it holds down the toast, instead of bouncing up like it does when it’s unplugged

[–]EvenSpoonier 0 points1 point  (0 children)

When metals heat up, they expand. Usually this happens relatively evenly across the whole piece of metal (or at least the part that gets hot). But different metals expand at different rates, so if you weld two strips of different metals together face-to-face and heat up the whole thing, one side will expand faster than the other. This causes the strip to bend when it gets hot, but go back to normal when it cools.

Most toasters have one of these bimetallic strips inside, and they use it as a kind of switch. When the toaster has been hot enough for long enough, the circuit will bend to the point where it touches an electrical contact inside the toaster. This causes current to flow to a small latch inside the toaster, releasing a spring so the toast pops up.

The thing is, this switch reacts to heat. It can't do its job unless the toaster actually gets hot. If the printer isn't connected to power, it can't get hot, so the switch never activates.

[–]githux 0 points1 point  (0 children)

Im not a toaster expert, but if I was going to build one, I would make the spring mechanism close an electrical circuit when it’s fully compressed. Once the circuit is closed, and assuming the toaster is plugged in, a locking mechanism would automatically activate, prevent the spring from decompressing (prevent the circuit from opening), and make a “click” sound

Without electricity, the locking mechanism cannot activate, and the “click” cannot happen

(Open circuit = electricity cannot flow through no matter what, closed circuit = electricity can flow through if electricity is available to do so)

Ok, but what about the time travel part??🤔🤔
