Below with reference to Fig. 1-Fig. 3 description according to the utility model first aspect embodiment for water basin dish-washing machine 200 Respirator 100, wherein water basin dish-washing machine 200 includes washing cavities 2011, and tableware to be washed is put in washing cavities 2011 and is washed.

As Figure 1-Figure 2, according to the respirator for water basin dish-washing machine 200 of the utility model first aspect embodiment 100 include shell.Drainage channel 1, intake tunnel 2 and air chamber 3 are limited in the inner cavity of shell, drainage channel 1 is equipped with sewage Import 11, outlet of sewer 12 and the drainage ventilation mouth 13 being communicated with the atmosphere, wastewater inlet 11 are connected with washing cavities 2011, and water inlet is logical Road 2 is equipped with water inlet 21, water outlet 22 and the water inlet blow vent 23 being communicated with the atmosphere, water outlet 22 and is connected to washing cavities 2011.

Specifically, air chamber 3 is equipped with pneumostome 31 and communication port 32, wherein pneumostome 31 is communicated with the atmosphere, communication port 32 are connected to washing cavities 2011, so that washing cavities 2011 are connected to atmosphere by air chamber 3, so as to balance washing cavities Pressure difference between 2011 and atmosphere, it is possible thereby to which the temperature in the washing cavities 2011 is avoided to change or carry out drying course etc. It causes the pressure in washing cavities 2011 excessive, guarantees the safe and reliable operation of water basin dish-washing machine 200.

Intake tunnel 2 is equipped with water inlet 21, water outlet 22 and water inlet blow vent 23, and wherein water inlet 21 is suitable for and tap water Pipe is connected, and water outlet 22 is connected to washing cavities 2011, and water inlet blow vent 23 is communicated with the atmosphere.

The water inlet process of water basin dish-washing machine 200 are as follows: after water is entered in intake tunnel 2 by water inlet 21, and pass through water outlet Mouth 22 drains into washing cavities 2011.When stopping supplying water towards in intake tunnel 2, the Upstream section of intake tunnel 2 forms negative pressure, makes Obtaining the water being detained in the tract of intake tunnel 2 has the trend to flow back by siphon, since water inlet blow vent 23 and atmosphere connect Logical, the air in atmosphere can be entered in intake tunnel 2 by water inlet blow vent 23, to balance the pressure difference in intake tunnel 2, be prevented Only there is siphonage in intake tunnel 2.

Drainage channel 1 is equipped with wastewater inlet 11, outlet of sewer 12 and drainage ventilation mouth 13, wherein wastewater inlet 11 and washing Chamber 2011 is connected to, and outlet of sewer 12 is suitable for and water passage, drainage ventilation mouth 13 and atmosphere.Water basin dish-washing machine 200 Drainage procedure are as follows: the wash water generated in washing cavities 2011 is entered in drainage channel 1 by wastewater inlet 11, then passes through dirt Water out 12 drains into sewer, to realize the drainage procedure of water basin dish-washing machine 200.

When stopping drainage procedure, negative pressure will be will form in the Upstream section of drainage channel 1, so that the row with water passage The water being detained in the tract of aquaporin 1 has the trend to flow back by siphon, due to drainage ventilation mouth 13 and atmosphere, greatly Air in gas can be entered in drainage channel 1 by drainage ventilation mouth 13, to balance the pressure difference in drainage channel 1, the row of preventing There is siphonage in aquaporin 1, thus it can be prevented that the water flow after draining in drainage channel 1 is back to washing for water basin dish-washing machine 200 It washs in chamber 2011, guarantees that the water being detained in drainage channel 1 is smoothly discharged.

Since the washing cavities 2011 of water basin dish-washing machine 200 are connected to by communication port 32 with air chamber 3, on the one hand, washing cavities Vapor in 2011 will be entered in air chamber 3 by communication port 32, and vapor condenses in air chamber 3 and forms drop, separately On the one hand, when the water level abnormality in the washing cavities 2011 of water basin dish-washing machine 200, the water in washing cavities 2011 will pass through connection Mouth 32 enters in air chamber 3, the water that a part will be stored in air chamber 3 is thereby resulted in, when the water level in air chamber 3 is increased to When higher than 31 place height of pneumostome, sink will be thereby resulted in by the outside spilling water of pneumostome 31 into the water in air chamber 3 Dish-washing machine 200 generates seepy question and influences the performance of water basin dish-washing machine 200.

To solve the above-mentioned problems, the air chamber 3 of the respirator 100 of the application is additionally provided with overflow port 33, it is possible to understand that ground, Height where overflow port 33 is lower than height where pneumostome 31, and overflow port 33 is suitable for being connected to sewer pipe, when in air chamber 3 When water level is higher than overflow port 33, air chamber 3 will be discharged by overflow port 33 in the water in air chamber 3, thus avoided in air chamber 3 Water level excessively high cause leak.

According to the respirator 100 for water basin dish-washing machine 200 of the utility model embodiment, washing cavities can be balanced 2011, the pressure between drainage channel 1 and intake tunnel 2 and atmosphere can prevent from washing when water basin dish-washing machine 200 works It washs that pressure in chamber 2011 is excessive, guarantees the safety of 200 course of work of water basin dish-washing machine, avoid drainage channel 1 and intake tunnel 2 Inside there is siphonage, the water in addition entered in air chamber 2 can also be discharged by overflow port 33, avoid 100 leak of respirator.
