The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] Reference below Figure 1-Figure 3 A breather 1000 of a dishwasher according to an embodiment of the present invention is described.

[0039] like Figure 1 As shown, a breather 1000 for a dishwasher according to an embodiment of the present invention includes: a housing 100 .

[0040] Specifically, a drainage channel 101, an air connecting channel 102 and an air cavity 103 are formed in the shell 100. The drainage channel 101 is formed at the lower part of the shell 100 and has a sewage inlet 1011, a sewage outlet 1012 and a drainage vent 1013 located between the sewage inlet 1011 and the sewage outlet 1012. The air connecting channel 102 includes an upward channel 1022 and a downward channel 1023. One end of the upward channel 1022 is connected to the drainage vent 1013 and the other end extends upward in a circuitous manner. The downward channel 1023 is connected to the other end of the upward channel 1022 and extends vertically downward. The air cavity 103 is connected to the lower end of the downward channel 1023. The air cavity 103 has a connecting port 1031 connected to the washing cavity of the dishwasher and a breathing port 1032 connected to the atmosphere. The connecting port 1031 is located below the lower end of the downward channel 1023, and the breathing port 1032 is spaced apart from the connecting port 1031.

[0041] That is to say, the drainage channel 101, the air connection channel 102 and the air cavity 103 are formed inside the shell 100. The drainage channel 101 is formed at the lower part of the shell 100. The drainage channel 101 has a sewage inlet 1011, a sewage outlet 1012 and a drainage vent 1013. The drainage vent 1013 is located between the sewage inlet 1011 and the sewage outlet 1012. The air connection channel 102 has an upward channel 1022 and a downward channel 1023. One end of the upward channel 1022 is connected to the drainage vent 1013, and the other end of the upward channel 1022 extends upward in a circuitous manner. The upward channel 1022 has a plurality of bends, which can effectively prevent dirt from accumulating in the shell 100. The downward channel 1023 is connected to the other end of the upward channel 1022, and the downward channel 1023 extends vertically downward, so as to avoid the accumulation of dirt in the downward channel 1023 and produce odor. The air cavity 103 is connected to the lower end of the downward channel 1023 (for example Figure 1The air cavity 103 is connected to the lower end of the downward channel 1023 as shown, the air cavity 103 has a connecting port 1031 and a breathing port 1032, the connecting port 1031 is connected to the washing cavity of the dishwasher, the connecting port 1031 is located below the lower end of the downward channel 1023, the breathing port 1032 is spaced apart from the connecting port 1031 and is connected to the atmosphere, which reduces heat loss and enhances the performance of the respirator 1000.

The downward channel 1023 extends downward vertically, and under the gravity of the water itself, the sewage is prevented from staying in the air-connecting channel 102, and the accumulation of residual food is avoided, thereby improving the performance of the respirator 1000. The communication port 1031 and the breathing port 1032 are both located in the air cavity 103. The breathing port 1032 is connected to the atmosphere to balance the air pressure inside and outside the dishwasher. The communication port 1031 and the breathing port 1032 are spaced apart from each other to reduce heat loss.

[0043] When the breather 1000 of the dishwasher is working, the washing wastewater generated in the washing cavity of the dishwasher enters the drainage channel 101 through the wastewater inlet 1011, and a part of the wastewater enters the drainage vent 1013. The breathing port 1032 is connected with the connecting port 1031, so that the washing cavity is connected with the atmosphere, thereby balancing the pressure difference between the washing cavity of the dishwasher and the atmosphere, avoiding excessive pressure in the washing cavity when the temperature in the washing cavity changes or the drying process is carried out, and ensuring the safe and reliable operation of the dishwasher; a part of the wastewater enters the wastewater outlet 1012, is discharged to the drainage pipe of the dishwasher, and is discharged outside the dishwasher.

[0044] According to the breather 1000 of the dishwasher according to the embodiment of the present invention, the length of the breather channel 102 is extended by providing a circuitously extending air connection channel 102, the area through which water flows is increased, the energy absorption area is increased, the heat in the sewage can be effectively transferred to the breather 1000 and the surrounding fresh water, and the possibility of dirt accumulation is reduced, and the generation of odor in the breather 1000 is reduced. The breathing port 1032 and the connecting port 1031 spaced apart from each other reduce the heat lost to the outside of the breather 1000, reduce the heat loss, improve the performance of the breather 1000, reduce the energy consumption of the dishwasher, balance the air pressure between the washing chamber of the dishwasher and the atmosphere, and improve the safety performance of the dishwasher.

[0045] In some embodiments of the present invention, the upward channel 1022 includes a plurality of arc-shaped extension segments, the arc-shaped extension segments extend in an arc, and the arc-shaped extension segments are sequentially connected in a direction from bottom to top. In other words, the upward channel 1022 has a plurality of arc-shaped extension segments, the arc-shaped extension segments are arc-shaped, and the arc-shaped extension segments are sequentially connected in a direction from bottom to top. Figure 1 As shown, the upward channel 1022 includes five arc-shaped extension segments, each of which is arc-shaped, and the five arc-shaped extension segments are connected in sequence from bottom to top. Therefore, the upward channel 1022 has a simple structure, and the multiple arc-shaped extension segments extend the length of the upward channel 1022, increase the distance that water flows, and improve the efficiency of heat recovery.

[0046] Further, the plurality of arc-shaped extension segments include: a first arc segment 10221, one end of the first arc segment 10221 is connected to the drainage vent 1013 and the other end extends upward along a circular arc or an elliptical arc, wherein the center angle of the first arc segment 10221 is not less than 90 degrees. In other words, the first arc segment 10221 is an arc-shaped extension segment, the drainage vent 1013 is connected to one end of the first arc segment 10221, the other end of the first arc segment 10221 extends upward along a circular arc or an elliptical arc, and the angle between the line connecting one end of the first arc segment 10221 and the center of the arc where the first arc segment 10221 is located and the line connecting the other end of the first arc segment 10221 and the center of the arc where the first arc segment 10221 is located is not less than 90 degrees. Thus, the length of the first arc segment 10221 is extended, and dirt accumulation in the first arc segment 10221 is avoided, and the structure is simple and easy to manufacture.

[0047] Furthermore, the plurality of arc-shaped extension segments further include: a second arc segment 10222, one end of the second arc segment 10222 is connected to the other end of the first arc segment 10221, the other end of the second arc segment 10222 extends upward along a circular arc or an elliptical arc, and the angle between a line connecting one end of the second arc segment 10222 and the center of the arc where the second arc segment 10222 is located and a line connecting the other end of the second arc segment 10222 and the center of the arc where the second arc segment 10222 is located is not greater than 90 degrees. Thus, the structure of the second arc segment 10222 is simple.

[0048] Furthermore, the multiple arc-shaped extension segments also include: a third arc segment 10223, one end of the third arc segment 10223 is connected to the other end of the second arc segment 10222, the other end of the third arc segment 10223 extends upward along a circular arc line or an elliptical arc line, the angle between a line connecting one end of the third arc segment 10223 and the center of the arc line where the third arc segment 10223 is located, and a line connecting the other end of the third arc segment 10223 and the center of the arc line where the third arc segment 10223 is located is not greater than 90 degrees, and the third arc segment 10223 has a simple structure.

[0049] Furthermore, the multiple arc-shaped extension segments also include: a fourth arc segment 10224, one end of the fourth arc segment 10224 is connected to the other end of the third arc segment 10223, the other end of the fourth arc segment 10224 extends upward along a circular arc line or an elliptical arc line, the angle between a line connecting one end of the fourth arc segment 10224 and the center of the arc line where the fourth arc segment 10224 is located, and a line connecting the other end of the fourth arc segment 10224 and the center of the arc line where the fourth arc segment 10224 is located is not greater than 90 degrees, and the fourth arc segment 10224 has a simple structure.

[0050] Furthermore, the multiple arc-shaped extension segments also include: a fifth arc segment 10225, one end of the fifth arc segment 10225 is connected to the other end of the fourth arc segment 10224, the other end of the fifth arc segment 10225 extends upward along a circular arc line or an elliptical arc line, the angle between a line connecting one end of the fifth arc segment 10225 and the center of the arc line where the fifth arc segment 10225 is located, and a line connecting the other end of the fifth arc segment 10225 and the center of the arc line where the fifth arc segment 10225 is located is not greater than 90 degrees, and the fifth arc segment 10225 has a simple structure.

[0051] Reference Figure 2As shown, the uplink channel 1022 includes: a first arc segment 10221 , a second arc segment 10222 , a third arc segment 10223 , a fourth arc segment 10224 and a fifth arc segment 10225 . In the direction from bottom to top, the first arc segment 10221, the second arc segment 10222, the third arc segment 10223, the fourth arc segment 10224 and the fifth arc segment 10225 are connected in sequence, the drainage vent 1013 is connected to the lower end of the first arc segment 10221, the upper end of the first arc segment 10221 is connected to the lower end of the second arc segment 10222, the upper end of the second arc segment 10222 is connected to the lower end of the third arc segment 10223, the upper end of the third arc segment 10223 is connected to the lower end of the fourth arc segment 10224, the upper end of the fourth arc segment 10224 is connected to the lower end of the fifth arc segment 10225, and there is a smooth transition between the first arc segment 10221, the second arc segment 10222, the third arc segment 10223, the fourth arc segment 10224 and the fifth arc segment 10225. As a result, the length of the upward channel 1022 is increased, and dirt accumulation is avoided.

[0052] In some embodiments of the present invention, the breather 1000 of the dishwasher further includes: an anti-siphon assembly 200. The anti-siphon assembly 200 is disposed in the air connection channel 102, and the anti-siphon assembly 200 is located between the upward channel 1022 and the downward channel 1023. The anti-siphon assembly 200 has an open state and a closed state. When the anti-siphon assembly 200 is in the open state, the upward channel 1022 and the downward channel 1023 are connected, and when the anti-siphon assembly 200 is in the closed state, the upward channel 1022 and the downward channel 1023 are disconnected. That is, the anti-siphon assembly 200 is disposed between the upward channel 1022 and the downward channel 1023 of the air connection channel 102, and the anti-siphon assembly 200 can be switched between an open state and a closed state. In the open state, the anti-siphon assembly 200 is open, and the upward channel 1022 and the downward channel 1023 of the air connection channel 102 are connected. In the closed state, the anti-siphon assembly 200 is closed, and the upward channel 1022 and the downward channel 1023 of the air connection channel 102 are disconnected. Therefore, the anti-siphon assembly 200 has a simple structure and is easy to use.

[0053] In some embodiments of the present invention, the air connection channel 102 further includes: a vortex chamber 1021, which is respectively connected to the upper end of the upward channel 1022 and the entrance of the anti-siphon assembly 200, thereby increasing the water retention area and reducing the possibility of dirt accumulation. When the washing sewage reaches the vortex chamber 1021, a vortex flushing effect is formed, and the accumulated materials are returned to the water under the action of the water flow, so that the dirt is taken away by the water. The anti-siphon assembly 200 is always kept in the best state, which improves the performance and reliability of the respirator 1000 and improves the user experience.

[0054] Furthermore, the upward channel 1022 is connected to one side of the vortex chamber 1021 , thereby enhancing the vortex power of water in the vortex chamber 1021 , allowing dirt to be carried away as much as possible under the power of the water itself, thereby ensuring the performance of the anti-siphon component 200 .

[0055] In some embodiments, the anti-siphon assembly 200 includes a door platform 201 and a check plate 202. Figure 3 As shown, the door platform 201 is arranged on the inner wall of the air connection channel 102, and the door platform 201 is located between the drainage vent 1013 and the breathing port 1032. The check piece 202 is rotatably arranged in the air connection channel 102, and the check piece 202 is located on the side of the door platform 201 facing the drainage vent 1013. The check piece 202 has an open position and a closed position. In the closed position, the check piece 202 is matched on the door platform 201 to cut off the air connection channel 102. In the open position, there is an air gap between the check piece 202 and the door platform 201 to circulate air.

[0056] During the normal drainage process of the dishwasher, after the sewage enters the drainage channel 101, it will be divided, with one part of the sewage flowing to the sewage outlet 1012 for discharge, and the other part will enter the air-connecting channel 102. Since the check piece 202 is always in the closed position during the normal drainage process, and since the check piece 202 is located on the side of the door platform 201 facing the drainage vent 1013, the door platform 201 restricts the check piece 202 from rotating toward the side close to the door platform 201. That is to say, when the water level of the sewage in the channel continues to rise and contacts the check piece 202, under the dual effects of the door platform 201 blocking the check piece 202 and the water pressure, the check piece 202 will fit tightly on the door platform 201, thereby cutting off the air-connecting channel 102, so that the sewage cannot flow into the air cavity 103 but flows to the breathing port 1032. Therefore, it can be achieved that when the dishwasher is draining normally, the sewage will not be discharged from the respirator 1000 through the breathing port 1032.

[0057] When negative pressure occurs upstream of the drainage channel 101, since the air pressure in the drainage channel 101 is lower than the external atmospheric pressure, the check piece 202 rotates in a direction away from the gate platform 201 under the action of external pressure, so that an air gap is formed between the check piece 202 and the gate platform 201 to allow air to flow. In this way, the pressure difference in the drainage channel 101 can be balanced, and the sewage in the drainage channel 101 can be prevented from flowing back.

[0058] Reference Figure 3As shown, the anti-siphon assembly 200 also includes a door shaft 203, which is arranged on the door platform 201, and a door hole 2021 is arranged on the check plate 202, and the door hole 2021 is sleeved on the door shaft 203. In this way, the check plate 202 can be rotated relative to the door platform 201, and the structure is very simple. The hole area of ​​the door hole 2021 is larger than the cross-sectional area of ​​the door shaft 203 located in the door hole 2021, and the rotation direction of the check plate 202 is perpendicular to the extension direction of the door shaft 203. In this way, it can be ensured that under the action of external pressure, the check plate 202 rotates so that a gap is formed between the check plate 202 and the door platform 201 to circulate air. The door hole 2021 is formed into a rectangle, and the door shaft 203 is formed into a cuboid. The free end of the door shaft 203 is provided with a cam (not shown). Thus, the check piece 202 can be prevented from excessively rotating under the effect of external pressure, so that the check piece 202 can be disengaged from the door shaft 203. The clamping protrusion is formed as a nut, and after the check piece 202 is fitted on the door shaft 203, the nut is fitted on the door shaft 203 with a certain distance between the nut and the check piece 202. Of course, the clamping protrusion can also be formed as other structures such as a retaining ring, etc.

[0059] A peripheral edge 204 is provided in the air connection channel 102 on one side of the check piece 202 facing the drainage vent 1013. It is understandable that when the check piece 202 is attached to the door platform 201, one side of the check piece 202 stops on the peripheral edge 204. This helps to ensure the sealing between the check piece 202 and the door platform 201 in the closed position, so that sewage will not be discharged from the air connection channel 102 when the dishwasher is draining normally. Specifically, the peripheral edge 204 is formed below the check piece 202. The check piece 202 is formed as a straight plate and is a rubber material. Such a structure is relatively simple and low in cost, and when the check piece 202 is in the closed position, it can better cut off the air connection channel 102.

[0060] It is understandable that in actual application, when the check piece 202 in the anti-siphon assembly 200 cooperates with the door platform 201, it cannot be guaranteed that there is no gap between the check piece 202 and the door platform 201, that is, the check piece 202 and the door platform 201 cannot be completely sealed. Therefore, the setting of the diversion channel can effectively prevent the sewage flowing into the air cavity 103 through the gap between the check piece 202 and the door platform 201 from being discharged from the dishwasher through the breathing port 1032, thereby improving the reliability of the respirator 1000, ensuring the safety performance of the dishwasher, and improving the user experience.

[0061] In some embodiments of the present invention, a guide rib 1033 is provided in the air cavity 103, at least part of which extends from the bottom of the descending channel 1023 to the connecting port 1031, and the guide rib 1033 is used to guide the sewage in the descending channel 1023 to the connecting port 1031. That is, the guide rib 1033 is provided in the air cavity 103, and the guide rib 1033 extends from the bottom of the descending channel 1023 to the connecting port 1031, and the guide has a guiding function, and is used to guide the washing sewage flowing out of the descending channel 1023 into the connecting port 1031. Therefore, the design of the guide rib 1033 is ingenious, which prevents the washing sewage from flowing to other parts of the respirator 1000, and improves the safety and reliability of the dishwasher.

[0062] In some embodiments of the present invention, a buffer rib 1034 is provided in the air cavity 103, at least part of the buffer rib 1034 extends along the circumference of the communication port 1031, and in the circumferential direction of the communication port 1031, at least part of the buffer rib 1034 protrudes outward in a direction away from the communication port 1031, so as to define a buffer space 10341 opening toward the communication port 1031. In other words, the buffer rib 1034 is provided in the air cavity 103, the buffer rib 1034 extends along the circumference of the communication port 1031, and at least part of the buffer rib 1034 protrudes in a direction away from the communication port 1031. Thus, the structure is simple, and the design of the buffer rib 1034 is reasonable and ingenious.

[0063] In some embodiments of the present invention, in the up-down direction, the upper edge of the buffer space 10341 is higher than the vertex of the communication port 1031. Figure 2 As shown, the buffer rib 1034 includes a first buffer rib 10342, a second buffer rib 10343 and a third buffer rib 10344. The right end of the first buffer rib 10324 is higher than the top of the connecting port 1031, and the right end of the first buffer rib 10342 is the lowest point of the first buffer rib 10342. Thus, the volume of the buffer space 10341 is increased, the kinetic energy of water is utilized to the maximum extent, and the performance of the respirator 1000 is improved.

[0064] In some embodiments of the present invention, the buffer rib 1034 is located below the guide rib 1033, and an airflow channel 105 is defined between the buffer rib 1034 and the guide rib 1033, one end of the airflow channel 105 is connected to the upper part of the connecting port 1031 and the other end extends upward obliquely or circuitously. In other words, the guide rib 1033 is located above the buffer rib 1034, and there is a certain gap between the buffer rib 1034 and the guide rib 1033. The airflow channel 105 is between the buffer rib 1034 and the guide rib 1033, one end of the airflow channel 105 is connected to the upper part of the connecting port 1031, and the other end of the airflow channel 105 extends upward or obliquely in a circuitous manner. Therefore, the airflow channel 105 has a simple structure and is easy to manufacture.

[0065] In some embodiments of the present invention, the air cavity 103 has a heat recovery space 104 located at the top of the air cavity 103, the heat recovery space 104 is connected to the upper end of the air flow channel 105, and the breathing port 1032 is located at the bottom of the air cavity 103 and communicates with the heat recovery space 104. In other words, the heat recovery space 104 is located at the top of the air cavity 103, the upper end of the air flow channel 105 is communicated with the heat recovery space 104, the breathing port 1032 is located at the bottom of the air cavity 103, and the heat recovery space 104 is communicated with the breathing port 1032. Since the heat moves upward, the heat recovery space 104 is located at the top of the air cavity 103, which reduces the loss of heat from the breathing port 1032, and the heat is effectively recovered, thereby improving the performance of the respirator 1000.

[0066] When the dishwasher is running, the temperature of the sewage in the washing chamber is higher than that of the normal temperature water, and the heat moves upward. Figure 2 As shown, there is an airflow channel 105 between the guide rib 1033 and the buffer rib 1034, the lower end of the airflow channel 105 is connected to the upper part of the connecting port 1031, the upper end of the airflow channel 105 is extended upward in a circuitous manner, and the upper end of the airflow channel 105 is connected to the heat recovery space 104 at the top of the air. In this way, the heat stays in the respirator 1000, and the respirator 1000 recovers the heat energy. When the dishwasher is filled with water, the heat in the respirator 1000 can be transferred to the water at normal temperature, thereby reducing the energy consumption of the dishwasher.

[0067] In some embodiments, a plurality of partition ribs 106 are provided between the heat recovery space 104 of the air cavity 103 and the breathing port 1032. The plurality of partition ribs 106 are arranged at intervals and each partition rib 106 extends in an oblique upward direction. Thus, the length of the gas from the heat recovery space 104 to the breathing port 1032 is extended, the heat recovery path is increased, the heat is recovered as much as possible, and the energy consumption of the respirator 1000 is reduced.

[0068] The following will refer to Figure 1-Figure 3 A breather 1000 for a dishwasher according to a specific embodiment of the present invention is described.

[0069] like Figure 1As shown, the breather 1000 of the dishwasher includes: a housing 100 and an anti-siphon assembly 200. The housing 100 has a drainage channel 101, an air connection channel 102, and an air cavity 103. The drainage channel 101 has a sewage inlet 1011, a sewage outlet 1012, and a drainage vent 1013. The air connection channel 102 includes a vortex cavity 1021, an upward channel 1022, and a downward channel 1023. The upward channel 1022 includes five arc-shaped extension sections. The air cavity 103 has a connecting port 1031, a breathing port 1032, a guide rib 1033, a buffer rib 1034, and a heat recovery space 104.

[0070] Specifically, the lower end of the upward channel 1022 is connected to the drainage vent 1013, and the five arc-shaped extension sections are connected in sequence. The upward channel 1022 extends upward in a circuitous manner. The upper end of the upward channel 1022 is connected to the vortex chamber 1021, and the vortex chamber 1021 is connected to the entrance of the anti-siphon component 200. The downward channel 1023 is connected to the outlet of the anti-siphon component 200. The guide rib 1033 extends to the connecting port 1031 below the downward channel 1023, and the buffer rib 1034 is located below the guide rib 1033. The buffer rib 1034 defines a buffer space 10341. The guide rib 1033 and the buffer rib 1034 are defined as an airflow channel 105. The top of the air cavity 103 is the heat recovery space 104. The breathing port 1032 is located at the bottom of the air cavity 103, and the breathing port 1032 is connected to the heat recovery space 104.

[0071] When the respirator 1000 of the dishwasher is working, the washing sewage generated in the washing chamber of the dishwasher enters the drainage channel 101 through the sewage inlet 1011, and a part of the sewage enters the drainage vent 1013. The sewage enters the upward channel 1022 of the connecting air channel 102, passes through the first arc segment 10221, the second arc segment 10222, the third arc segment 10223, the fourth arc segment 10224 and the fifth arc segment 10225 of the upward channel 1022, reaches the vortex cavity 1021, and then enters the anti-siphon component 200, and then enters the downward channel 1023. After being guided by the guide rib 1033, the sewage enters the connecting port 1031. When the sewage flow is too large, the sewage is in the buffer space 10341 and then enters the connecting port 1031. The heat of the sewage enters the heat recovery space 104 through the air flow channel 105; another part of the sewage enters the sewage outlet 1012, is discharged to the drainage pipe of the dishwasher, and is discharged outside the dishwasher.

[0072] As a result, the length of the air connection channel 102 in the respirator 1000 is extended, the area through which water flows is increased, the energy absorption area is increased, the heat in the sewage can be effectively transferred to the respirator 1000 and the surrounding fresh water, and the possibility of dirt accumulation is reduced, the generation of odor in the respirator 1000 is reduced, the kinetic energy of water is effectively used, and the kinetic energy is effectively converted into self-cleaning, thereby reducing the self-cleaning energy consumption, reducing the heat lost to the outside of the respirator 1000, reducing heat loss, improving the performance of the respirator 1000, reducing the energy consumption of the dishwasher, balancing the air pressure between the washing chamber of the dishwasher and the atmosphere, and improving the safety performance of the dishwasher.

[0073] The dishwasher according to the second embodiment of the present invention comprises the breather 1000 of the dishwasher according to the first embodiment of the present invention.
