How does the electric pressure door opener work?

Thanks, even in the Blum video they don't have trash can lids!

I would really like the electric push-to-open device but two things bother me about it:
-The part is expensive and requires a standby current

To what extent the 3.5 kWh per year is economically/ecologically justifiable is something everyone has to decide for themselves. You should consider how you behave otherwise. For example, an old video recorder in standby will consume much more.

-What use is the automatic opening of the drawer if I then can't open the trash can lid with my hands full?

Do you really need the lid? If the trash starts to stink, it's high time to take it out. The underside of the lid usually looks anything but clean. Do you always clean it thoroughly?

Questions:
Can the drawer of the pull-out also be mounted slightly tilted (front a bit lower than the back), so the drawer would always open fully?

Front lower will not work because the rail already rests at the bottom on the cabinet, but the back could be a bit higher. Then you need to file a hole in the rail a little bit and put something under the rail. However, you accept that the front does not fit evenly on the cabinet when the drawer is closed, unless you tinker accordingly with the front mounting.

Apparently there is no solution at IKEA for automatic opening of the trash can lid. Does anyone know solutions from other manufacturers that could be installed in the IKEA pull-out which mechanically open the trash can lid when opening?

Then you will have to take a completely different solution, e.g. from Franke. Or make something yourself.

In my current kitchen (also about 20 years old) I also have such an automatic push-to-open device, but purely mechanical, not electric. You have to tap a lever under the drawer with your foot (which you still have free), then mechanically, driven by spring force, the drawer opens. When closing the drawer, the spring is tensioned again.
I will look into whether such a mechanical solution can somehow be realized in the IKEA drawer.
Anyone with good ideas, please get in touch.

I always find simple mechanical solutions better. Some people simply won't like it visually.
The spring is a problem because it would compete with the spring of the self-closing mechanism of the drawer.

Ikea expert, thank you for your helpful answer. I have now found what I was looking for, at home we have exactly this one: We rarely to never clean the lid and it is also not necessary, probably because we can’t overfill the bins anyway, otherwise we can’t close the drawer. For us, the front of this waste separator is screwed to the drawer front, i.e. when opening the drawer, the bins are pulled out with it and the lid stays inside. We have this with such a foot pedal spring, after tapping with the foot everything automatically slides out and when closing, the spring tensions. I didn’t know that IKEA drawers with dampers have a return spring. I thought only the closing impact was damped. With a waste drawer, the automatic extension is more important to me than the self-retraction, so for me a solution would be to do without the self-extension and install a "normal," undamped drawer slide. Does Ikea have something like this or do you have to buy it again from a specialist dealer??? Or I will try, as already mentioned, with a slope of the drawer. One more thing: We want to have the large domsjö sink in the 80 cm base cabinet with drawer. Can I find out anywhere how much space this base cabinet provides me for a waste separation system? I mean, the water hoses, siphons, etc. also need some space. In my closest Ikea store, there is an 80 cm Domsjö base cabinet without drawer (but with mounted siphons) and an 80 cm with drawer but with a different sink on display. Do I have to go there again and measure the free space under the sink or can I find this information somewhere else? Best regards Section chief

If anyone is interested: I have now found a double trash bin that can be mounted in a drawer and whose lid opens automatically when the drawer is pulled out. It is the model Ökoflex 3434. It can also be combined with a foot pedal, which then opens the drawer automatically when you tap with your foot at the baseboard. Now I just need to clarify whether this fits into the base cabinet with drawer of a Domsjö sink, according to the brochure I need a free height of at least 431mm and a depth of 372mm.
Best regards

That should be no problem...

Nice that you found something suitable for yourself. The dimension drawings specify a max. width of 60 cm. Have you taken that into account? I suspect it has to do with the attachment of the lid. I would clarify that with Hailo beforehand.

Yes, that's correct. Thanks for the hint. I am currently trying to find a Hailo showroom/dealer in Vienna where I can look at this system. The waste separator we have in our current apartment is designed for 30 cm drawers but is installed on the left side in a 60 cm base cabinet. The opposite lid mounting was also attached on the left side with a metal bracket. I think it can be done similarly with the 3434, but I need to clarify that. Best regards Section Chief
