Gas passage 120 has drainage ventilation mouth 121 and a pneumostome 122, the communicated drainage passage 110 of drainage ventilation mouth 121 and is located at sewage
Between import 111 and outlet of sewer 112, pneumostome 122 connects ambient atmosphere.
As shown in Fig. 2 check valve 20 includes valve body 210 and valve element 240, and in the company's of the being located at gas passage 120 of valve body 210, valve body
External tapping 214 and inner joint 213 are respectively equipped with 210 opposing sidewalls, external tapping 214 connects pneumostome 122, inner joint 213
Communicated drainage blow vent 121, valve element 240 have limiting section 241 and closure part 242, and limiting section 241 coordinates in inner joint 213
And bearing of trend of the limitation valve element 240 along inner joint 213 may move, what closure part 242 was located at limiting section 241 is located at valve body 210
Interior one end, valve element 240 have open position and closed position, and at closed position, closure part 242 is only against setting for valve body 210
Put in the side wall of external tapping 214 and block external tapping 214 (as shown in Figure 3), closure part 242 is only against valve body at open position
Air gap is formed with ventilating air (as shown in Figure 4) in the side wall of 210 setting inner joint 213 and between inner joint 213.
It should be noted that the wastewater inlet 111 of respirator 100 connects with the washing cavities of dish-washing machine, outlet of sewer
112112 are suitable to and water passage, drainage ventilation mouth 121 and atmosphere.The drainage procedure of water tank type dish-washing machine is：Washing
Wash water caused by intracavitary is entered in drainage channel 110 by wastewater inlet 111, is then drained into by outlet of sewer 112112
In sewer, so as to realize the drainage procedure of water basin dish-washing machine.When stopping drainage procedure, in the Upstream section of drainage channel 110
Negative pressure will be formed so that have with the water being detained in the tract of the drainage channel 110 of water passage and flowed back because of siphon
Trend, due to drainage ventilation mouth 121 and atmosphere, the air in air can enter draining by drainage ventilation mouth 121
In passage 110, to balance the pressure difference in drainage channel 110, prevent drainage channel 110 from siphonage occur, thus it can be prevented that
Current after draining in drainage channel 110 are back in the washing cavities of water basin dish-washing machine, ensure that the water of delay in drainage channel 110 is suitable
Profit discharge.
It is understood that during dish-washing machine proper drainage, sewage can produce shunting after entering drainage channel 110,
A part of sewage flows to outlet of sewer 112112 and discharged, and another part will enter even gas passage 120.Constantly rise when water level and
When touching non-return piece, because the external tapping 214 of valve body 210 can be closed in the closure part 242 of buoyancy valve element 240 so that
Sewage can not be flowed out at pneumostome 122 from external tapping 214.Hereby it is achieved that during dish-washing machine proper drainage, sewage without going past
Pneumostome 122 discharges respirator 100.Prevent sewage from spilling can in addition, moving the mode of closing external tapping 214 using valve element 240
By property is higher, stability is preferable.
When there is negative pressure in the upstream of drainage channel 110, because the air pressure in drainage channel 110 is less than external atmosphere pressure,

241 can limit the moving direction of closure part 242, it is therefore prevented that cause external tapping 214 to be closed not because closure part 242 shifts
Tight phenomenon occurs.
The respirator 100 of dish-washing machine according to embodiments of the present invention, due to being opened or closed in interior be provided with of even gas passage 120
Connect pneumostome 122 external tapping 214 valve element 240, when can preferably ensure dish-washing machine proper drainage, sewage without going past
Pneumostome 122 discharges respirator 100, and and can balances the pressure difference in drainage channel 110, prevents the sewage in drainage channel 110 from going out
The phenomenon now to flow back occurs.In addition, the mode that pneumostome 122 is opened or closed using the motion of non-return piece is very reliable and steady
It is fixed, and service life is longer.
In certain embodiments, as shown in Fig. 2 check valve 20 also includes seal 250, seal 250 is located at valve element 240
The side towards pneumostome 122.Thereby ensure that when valve element 240 is in the closed position closure part 242 and external tapping 214 it
Between sealing, so as to ensure that sewage will not be flowed out at pneumostome 122 through external tapping 214.
Specifically, seal 250 is O-ring seal.The sealing effectiveness of O sealing rings is preferable, and certain seal 250 may be used also
Think the sealing ring of other forms.
In certain embodiments, limiting section 241 and closure part 242 are the cylinder along the moving direction extension of valve element 240
Shape.Thus, the processing of limiting section 241 and closure part 242 is relatively easy to, and certain limiting section 241 and closure part 242 can also be formed
For shapes such as other shapes, such as cuboid, triangular prisms.
In certain embodiments, as shown in Fig. 2 valve element 240 also includes the remote closure part 242 for being located at limiting section 241
The afterbody 243 of one end, and on the direction away from closure part 242, the sectional dimension of afterbody 243 gradually increases.It is appreciated that
It is if that, arrangement afterbody 243, when water level is higher, the limiting section 241 of valve element 240 may depart from inner joint 213, so work as water level
During reduction, the phenomenon for deviateing inner joint 213 occurs in limiting section 241, is so unfavorable for the envelope of closure part 242 when water level rises again
Stifled external tapping 214.Therefore, the direction upper section size that closure part 242 is arranged far from one end away from closure part 242 is gradual
The afterbody 243 of increase can make it that no matter how high water level is, and all far less likely to occur limiting section 241 departs from the phenomenon of inner joint 213
Occur.In summary, the afterbody 243 of the one end of core also including the remote closure part 242 for being located at limiting section 241 can ensure to block
The plugging action in portion 242, improve the reliability of valve element 240.
Favourable, the sectional dimension maximum of afterbody 243 is more than the internal diameter of inner joint 213.Thus, no matter how high water level is,
It is impossible to the phenomenon generation that limiting section 241 departs from inner joint 213 occur, further increases the reliability of valve element 240.
In certain embodiments, the displacement of valve element 240 and the axial dimension sum of inner joint 213 are less than limiting section
241 axial dimension.It is understood that if the axial dimension of limiting section 241 is less than the displacement of valve element 240 and is inscribed
The axial dimension of mouth 213, then be likely to occur situations below：First, valve element 240 move to peak closure part 242 still can be complete
The phenomenon of full closure external tapping 214, this phenomenon can cause sewage to be flowed out from external tapping 214.Second, closure part 242 blocks outside
Limiting section 241 has completely disengaged the phenomenon of inner joint 213 during interface 214, and such phenomenon can cause so when water level reduces
When limiting section 241 occur deviate inner joint 213 so that when water level rises again closure part 242 can not block completely it is external
The situation of mouth 214 occurs.Therefore, the displacement of valve element 240 and the axial dimension sum of inner joint 213 are less than limiting section 241
Axial dimension can both ensure that valve element 240 moved to peak closure part 242 and can necessarily block external tapping 214 completely, again
It can ensure that limiting section 241 coordinates in inner joint 213 all the time, ensure that the plugging effect of closure part 242.
In certain embodiments, as shown in Fig. 2 external tapping 214 is located on the roof of valve body 210, inner joint 213 is arranged on
On the bottom wall of valve body 210, valve element 240 moves along the vertical direction.Thus, when negative pressure is smaller in exhaust passage, valve element 240 also may be used
The pressure difference of exhaust passage is balanced in the presence of self gravitation, to fall back to open position.Therefore, external tapping 214 is located at
On the roof of valve body 210, inner joint 213 is arranged on the bottom wall of valve body 210, and valve element 240 moves along the vertical direction so that unidirectional
Valve 20 is very sensitive to the pressure difference in exhaust passage, so as to enhance the effect of balance pressure difference.
In certain embodiments, as shown in Fig. 2 the bottom of closure part 241 is formed as cutting with the part that limiting section 241 is connected
The tapered portion 2411 that face area tapers into downwards, and when the outer peripheral face of tapered portion 2411 is only against on the end face of inner joint 213
When, area of the cross-sectional area less than inner joint 213 of the tapered portion 2411 is cut in the end face of inner joint 213.
It is understood that when when the water level even in gas passage 120 is relatively low and does not have valve element 240, valve element 240 exists
Free-falling causes the outer peripheral face of tapered portion 2411 to be only against on the end face of inner joint 213 in the presence of gravity, due to inner joint
213 end face cut tapered portion 2411 cross-sectional area be less than inner joint 213 area, therefore, now gas remain to from
Inner joint 213 enters and flows to drainage ventilation mouth 121.In summary, water in the company's of the ensure that gas passage 120 of tapered portion 2411 is set
When position is too low, gas remains to enter and flow to drainage ventilation mouth 121 from inner joint 213, so as to ensure that the balance of check valve 20
The ability of pressure difference in drainage channel 120.
