Detailed implementation manners

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] This embodiment discloses a dishwasher breather. Refer to Figures 1-4 As shown, it includes a housing 1, and a water inlet chamber 3 and a drainage chamber 4 are formed in the housing 1. The water inlet chamber 3 is used for the water inlet of the dishwasher, and is provided with a first water inlet 31 and a first water outlet 32. The water input into the dishwasher is input from the first water inlet 31, flows through the water inlet chamber 3, and is output from the first water outlet 32 for the dishwasher to use. The drainage chamber 4 is used for discharging the sewage in the dishwasher, and is provided with a second water inlet 41 and a second water outlet 42. The sewage is output from the second water inlet 41, flows through the drainage chamber 4, and is discharged from the second water outlet 42.

[0032] The housing 1 includes a bottom case 11 and a cover 12. A plurality of partitions are integrally formed in the housing 1 to divide the inner cavity of the bottom case 11 into corresponding chambers and flow channels; the shape profile of the cover 12 is adapted to that of the bottom case 11, and the cover 12 is fixedly connected to the bottom case 11 and can cover the bottom case 11. The two can be connected and fixed by hot melting, or other appropriate methods can also be used for fixing.

[0033] The dishwasher breather in this embodiment further includes a flow meter module 5, through which the water flow rate in the water inlet chamber 3 can be detected, and then the water inlet volume of the dishwasher can be detected.

[0034] Specifically, a flow detection chamber 111 is formed in the bottom case 11, and the detection chamber 111 is communicated with the water inlet chamber 3. The flow channel between the first water outlet 32 and the first water outlet 32 flows through the flow detection chamber 111, and the flow detection chamber 111 is located on the side close to the first water inlet 31. The flow detection chamber 111 is provided with an open end, and the flow meter module 5 can be installed at the open end.

[0035] Reference Figure 2 、 Figure 3 、 Figure 8 As shown, the flowmeter module 5 includes a flowmeter body 51 and a rotary vane 52. The flowmeter body 51 is fixedly installed at the open end of the flow detection chamber 111 to cover the flow detection chamber 111. The flowmeter body 51 can be fixedly connected to the bottom case 11 through bolts, and the connection part is sealed through a seal. The rotary vane 52 of the flowmeter module 5 extends into the flow detection chamber 111, and the rotary vane 52 can interact with the flowing water, thereby detecting the flow rate. Specifically, the flowmeter module 5 can adopt the principle of a Hall flowmeter, which will not be elaborated here.

[0036] The cover body 12 is provided with a relief notch 121, and the relief notch 121 is opposite to the open end of the flow detection chamber 111. After the cover body 12 and the bottom case 11 are covered with each other, the relief notch 121 is exactly opposite to the position of the flow detection chamber 111, which is convenient for installing the flowmeter module 5 through the relief notch 121 after the two are covered and fixed. At least part of the flowmeter body 51 is exposed outside the housing 1 from the relief notch 121, which is convenient for installing and later overhauling and maintaining the flowmeter module 5.

[0037] Reference Figure 4 As shown, an air vent chamber 6 is provided in the housing 1. The air vent chamber 6 is communicated with the external environment. The air vent chamber 6 is provided with an inner tank interface 61. Through the air vent chamber 6, the inner tank of the dishwasher can be communicated with the external environment, and the air pressure in the inner tank of the dishwasher can be balanced.

[0038] Reference Figure 3 、 Figure 4 、 Figure 5 As shown, the water inlet chamber 3 includes a throttling section 33, and the throttling section 33 is generally in an arc-shaped structure. Moreover, a communication notch 331 is provided between the throttling section 33 and the air vent chamber 6, and the communication notch 331 communicates downward with the air vent chamber 6.

[0039] Reference Figure 5 、 Figure 6 、 Figure 7 As shown, a throttle piece 7 is provided at the communication notch 331. The shape of the throttle piece 7 is adapted to the shapes of the throttling section 33 and the communication notch 331. The throttle piece 7 can limit the flow channel in the water inlet chamber 3, and ventilation holes 72 are formed between the water inlet chamber 3 and the inner wall of the housing 1. The ventilation holes 72 communicate the throttling section 33 of the water inlet chamber 3 with the air vent chamber 6, and the throttling section 33 is located above the air vent chamber 6.

[0040] Specifically, the throttling section 33 is in an arc-shaped structure, part of the throttle piece 7 is embedded in the throttling section 33, and part is embedded in the communication notch 331. Reference Figure 6 、 Figure 7As shown in the figure, a bump 71 is fixedly connected to the throttle piece 7. The bump 71 abuts against the inner wall of the bottom shell 11, which can support and limit the position of the throttle piece 7. Furthermore, the air vent hole 72 can be formed between the throttle piece 7 and the inner wall of the bottom shell 11, allowing air to pass through.

[0041] When the water flow circulates normally in the water inlet chamber 3, the water flow enters from the first water inlet 31, circulates along the water inlet chamber 3, passes through the throttle section 33 and the throttle piece 7. Most of the water continues to circulate in the water inlet chamber 3 after passing through the throttle section 33, and finally is output from the first water outlet 32; a small part of the water enters the first ventilation chamber 6 through the air vent hole 72 of the throttle piece 7, and then flows from the first ventilation chamber 6 into the inner tank of the dishwasher. When the valve plug at the first water inlet 31 sucks back, the gas enters the water inlet chamber 3 through the air vent hole 72 of the throttle piece 7, destroying the siphon state in the water inlet chamber 3, preventing the water inlet chamber 3 from generating backflow, and preventing the sewage in the inner tank from being sucked out and flowing into the tap water pipe to pollute the water source.

[0042] Refer to Figure 4 As shown in the figure, a second ventilation chamber 8 is provided in the housing 1. The second ventilation chamber 8 is communicated with the drainage chamber 4, and a through hole 82 is provided in the second ventilation chamber 8. A one-way valve 9 is provided at the through hole 82, and the one-way valve 9 can conduct unidirectionally from the through hole 82 to the second ventilation chamber 8.

[0043] Specifically, the second ventilation chamber 8 is communicated with the drainage chamber 4 through a communication gap 81, and the communication gap 81 is close to the second water outlet 42 side of the drainage chamber 4. The second ventilation chamber 8 is located above the drainage chamber 4, and the through hole 82 is provided at the top of the second ventilation chamber 8. The through hole 82 can be communicated with the external environment, allowing the external atmosphere to enter the second ventilation chamber 8 and the drainage chamber 4.

[0044] Refer to Figure 9 As shown in the figure, the one-way valve 9 includes a valve body 91, a spring 92 and a valve block 93. The valve body 91 is installed in the second ventilation chamber 8, and both the spring 92 and the valve block 93 are supported by the valve body 91. The spring 92 acts elastically between the valve body 91 and the valve block 93, and the valve block 93 is pressed against and covers the through hole 82 by the elastic force of the spring 92, which can close the through hole 82. When the pressure inside the second ventilation chamber 8 drops, the external atmospheric pressure will push the valve block 93 to open the through hole 82, so that the second ventilation chamber 8 and the drainage chamber 4 are communicated with the external environment.

[0045] Furthermore, in order to improve the movement stability of the valve block 93, a guide rod 94 can be fixedly connected to the upper side wall of the second ventilation chamber 8, and a corresponding and adapted guide hole 95 is provided in the valve block 93. The guide rod 94 is inserted into the guide hole 95 to maintain the movement stability of the valve block 93.

[0046] When the dishwasher finishes draining, the water in the drainage cavity 4 is at a high level. Due to the gravity of the water, it will flow downward, creating a downward suction in the drainage cavity 4, which in turn causes the pressure in the second ventilation cavity 8 to drop. At this time, the one-way valve 9 is pressed down by the external pressure, and the through-hole 82 is opened, connecting the second ventilation cavity 8 and the drainage cavity 4 to the external environment, allowing the water in the drainage cavity 4 to drain smoothly. The second water inlet of the drainage cavity 4 is connected to the dishwasher inner tank. When the inner tank is refilled with water again, the water in the inner tank may be directly siphoned out by the siphon in the drainage cavity 4. At this time, the pressure in the second ventilation cavity 8 is less than the external atmospheric pressure, and the external atmospheric pressure at the through-hole 82 will push the valve block 93 to open the through-hole 82, breaking the siphon in the drainage cavity 4 and preventing the water in the inner tank from being directly siphoned out.

[0047] This embodiment also discloses a dishwasher, including the dishwasher breather in the above embodiment. A plurality of flow paths of the dishwasher are integrated in the dishwasher breather, and it can balance the pressure difference environment of each flow path of the dishwasher and the inner tank, balance the working pressure of the dishwasher, and keep the dishwasher working normally and stably.

[0048] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
