Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1-10, the respirator of the dishwasher comprises an upper shell 1 and a lower shell 2, wherein a breathing port 3 is arranged on the upper shell 1 or the lower shell 2, the upper shell 1 and the lower shell 2 are fixedly connected with each other, and a water supply channel 4, a water drainage channel 5, a condensation channel 6, a first anti-siphon channel 7, a second anti-siphon channel 8 and a regeneration water cavity 9 which are communicated with each other are formed inside the upper shell 1 and the lower shell 2.
The breathing port 3 is positioned on the left side of the water supply channel 4, the inner wall of the breathing port is provided with a disconnected thread part 10, the disconnected thread part 10 is formed by an inclined top, and the disconnected thread part 10 can be arranged in a mode of avoiding a mold structure in a screw rod mode and an insert mode, so that the mold of the respirator is simple to manufacture, and the development cost is reduced.
The breathing port 3 is communicated with the water supply channel 4, and/or the water drainage channel 5, and/or the condensation channel 6, and/or the first anti-siphon channel 7, and/or the second anti-siphon channel 8, and/or the regeneration water cavity 9; the first anti-siphon channel 7 is at least partially positioned below the water supply channel 4 and passes through the water supply channel 4.
Furthermore, the water supply channel 4 is provided with a water inlet 11, a water outlet 12, a flow limiting pipe mounting part 13, a flow meter mounting part 14, a flow splitting block mounting part 15 and a water inlet siphon port 16; wherein, the water inlet 11 is communicated with a water supply pipe 18, and the water outlet 12 is communicated with a water softener 19; the top of the water supply channel 4 is provided with a circuitous pipeline 20, the diversion block mounting part 15 is positioned in the circuitous pipeline 20 and is provided with a diversion block 21, and the water inlet siphon port 16 is arranged below the diversion block 21.
Further, an atmosphere vent 22 is arranged on the upper shell 1 or the lower shell 2; the water inlet siphon mouth 16, the atmospheric vent 22 and the breathing port 3 are communicated with each other to form a first anti-siphon channel 7, and the middle part of the first anti-siphon channel 7 is positioned below the water supply channel 4 and passes through the lower part of the water supply channel 4. The design between the first anti-siphon channel 7 and the water supply channel 4 can solve the problem of complicated structure of the siphon caused by the breathing port 3 positioned at the left side of the water supply channel 4.
The working principle is as follows: due to the action of the circuitous pipeline 20 and the diversion block 21, the speed of water is increased when the water passes through the diversion block 21, and the water is quickly cut through the upwardly convex circular circuitous pipeline 20, so that the water does not flow out of the water inlet siphon port 16 and can keep the function of communicating with the atmosphere; when negative pressure is generated at the water inlet 11, water in the water supply channel 4 and the water softener 19 connected with the water supply channel will tend to flow back due to siphon, but because the water inlet siphon port 16 is communicated with the atmosphere, air in the atmosphere can enter the water supply channel 4 through the water inlet siphon port 16, and the negative pressure of the water inlet 11 is parallel to ensure that the water in the water supply channel 4 cannot flow back.
Further, a flow restrictor 23 is mounted on the flow restrictor mounting part 13, and a flow meter 24 and an impeller 25 are mounted on the flow meter mounting part 14.

Further, the drainage siphon port 28 is located on the side wall of the inverted U-shaped guide section of the drainage channel 5, is communicated with the breathing port 3 and forms a second anti-siphon channel 8; an anti-siphon one-way valve installation part 31 is arranged above the drainage siphon port 28, the anti-siphon one-way valve installation part 31 is a cylindrical channel, an anti-siphon one-way valve 32 is assembled on the anti-siphon one-way valve installation part 31, and the anti-siphon one-way valve 32 is assembled on the anti-siphon one-way valve installation part 31 in a manner that a closed end is downward in a sharp mouth and an opening is upward; the upper shell 1 or the lower shell 2 is also provided with an anti-falling rib 33 corresponding to the anti-siphon one-way valve 32.
The working principle of the second anti-siphon channel 8 is as follows: when the dishwasher drains, sewage enters the first drainage port 26 through the inner drainage pipe 29 and then is discharged to a sewer from the second drainage port 27 through the outer drainage pipe 30 through the drainage channel 5, so that the drainage action of the dishwasher is realized; when the drainage pump stops working, the right pipeline of the inverted U-shaped drainage channel 5 generates negative pressure, so that water in the inverted U-shaped left pipeline connected with the outer drainage pipe 30 has a tendency of flowing back due to siphoning; when the drainage action of the dish-washing machine is finished, when negative pressure is generated in an outer drainage pipe 30 connected with a sewer due to the self-flowing effect, water in a water tank can be sucked, and the dish-washing machine is insufficient in water inlet in the next step; because the second anti-siphon channel 8 is connected with the breathing port 3, the atmosphere in the air enters the drainage channel 5 from the second anti-siphon channel 8, so that the negative pressure in the drainage channel 5 is balanced, the water in the drainage channel 5 is drained smoothly, and the influence on the dish-washing machine is avoided.
It can be understood that, in the normal drainage process of the dishwasher, part of water will reach the anti-siphon check valve 32 through the drainage siphon inlet 28, at this time, due to the action of water pressure, the closed end tip of the anti-siphon check valve 32 is pressed tightly by water pressure, and the sewage can not enter the inner container 39 through the second anti-siphon channel 8 and the breathing port 3; meanwhile, the lower case 2 is further provided with a separation prevention rib 33 corresponding to the anti-siphon check valve 32, and the separation prevention rib 33 can prevent the anti-siphon check valve 32 from being released due to water pressure.
