The design and working principle of the kitchen air conditioner

The "pumping" of the flush toilet refers to the S-shaped bend under the toilet, and when the water surface in the toilet exceeds the high point of the S-bend, the siphon phenomenon is formed, which can pump the water and dirt of the toilet together. Until only a small amount of water remains, the siphon destroys, leaving a small amount of water, forming a water seal. >>>More

Rely on the float to stop the water in the inlet valve; The drain is lifted by pressing the switch or the old-fashioned cable switch, so as to form a siphon to let the water flow out quickly, a large amount of water enters the toilet bowl beyond the toilet drain S bend height, and the drain forms a siphon, which quickly takes away the internal dirt, and after the water volume is reduced, a small amount of water is left to seal the S bend hole to prevent the drain from smelling out.

I used to look like I had only one that relied on buoyancy.

The suction cup can suck the wall is to squeeze the air inside the suction cup when extruding the suction cup, so that the air pressure inside the suction cup is far less than the external air pressure, so that there is great pressure on the external surface of the suction cup to press the suction cup on the wall, under this huge pressure, if the wall surface is not smooth enough, so that the outside air will be pressed into the inside of the suction cup through the small gap in the connection between the suction cup and the wall, the internal air pressure will increase, and the external atmospheric pressure will not change, so that the difference between the internal and external air pressure will decrease, and the pressure on the outer surface of the suction cup will decrease, Suction cups are naturally easy to drop. >>>More

Its working principle is as follows: the compressor compresses the refluxed low-pressure refrigerant, becomes a high-temperature and high-pressure gas discharge, the high-temperature and high-pressure refrigerant gas flows through the copper pipe wound outside the water tank, the heat is conducted into the water tank through the copper pipe, the cooled refrigerant becomes liquid under the continuous action of pressure, and enters the evaporator after the expansion valve, because the pressure of the evaporator decreases suddenly, so the liquid refrigerant quickly evaporates into a gaseous state here, and absorbs a large amount of heat. At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, the energy in the air is absorbed by the evaporator, the air temperature decreases rapidly, and becomes a cold air discharged into the kitchen, and then the refrigerant that absorbs a certain amount of energy flows back to the compressor and enters the next cycle. >>>More
