[0003] During the washing process of a dishwasher, water is heated to better wash tableware. The water vapor will increase the air pressure in the washing cavity of the dishwasher, and a breather can be used to balance the pressure between the washing cavity and the outside atmosphere.

[0004] In the related art, a large amount of hot and humid air in the washing cavity can be directly discharged to the outside through the breather, which is not conducive to the heat preservation and energy saving of the dishwasher. Summary of the Invention

[0005] The main object of the present invention is to propose a breather, aiming to enable the dishwasher to preserve heat and save energy, thereby reducing the energy consumption of the dishwasher.

[0006] To achieve the above object, the breather proposed by the present invention is used for a dishwasher. The dishwasher includes a body, and a washing cavity is provided in the body. The breather includes:

[0036] The present invention provides a respirator for a dishwasher. Without loss of generality, the dishwasher includes a body, and a washing cavity is provided inside the body. The respirator is installed on the body.

[0037] Refer to Figures 1 to 4 , in an embodiment of the present invention, the respirator 1 includes:

[0038] A housing 10, an air cavity 101 is defined inside the housing 10, the air cavity 101 is provided with a breathing port 101a for communicating with the atmosphere, a communication port 101b for communicating with the washing cavity 20, and a condensation cavity 101c adjacent to the communication port 101b;

[0039] The condensation cavity 101c is not lower than the lower edge of the communication port 101b, and the opening of the condensation cavity 101c faces the communication port 101b.

[0040] Through the technical solution of the present invention, by adding a condensation cavity 101c with an opening facing the communication port 101b, the leakage of hot and humid air can be reduced through the condensation cavity 101c. At the same time, multiple cavity walls of the condensation cavity 101c can provide a condensation effect, with a high condensation efficiency, and can well recover the heat energy in the hot and humid air. Moreover, the condensed water condensed by the condensation cavity 101c can flow back to the communication port 101b through its opening and then flow back to the washing cavity 20 through the communication port 101b to achieve the recovery of condensed water, thereby enabling the dishwasher to keep warm and save energy and reducing the energy consumption of the dishwasher.

[0041] Without loss of generality, in this embodiment, the condensation chamber 101c has a lower chamber wall, and one end of the lower chamber wall close to the communication port 101b constructs the lower edge of the opening of the condensation chamber 101c. Optionally, the lower chamber wall extends obliquely downward; in this way, on the one hand, the length of the lower chamber wall can be extended to increase the condensation capacity of the lower chamber wall, and on the other hand, it is also beneficial for the condensed water condensed in the condensation chamber 101c to flow back to the communication port 101b.

[0042] In this embodiment, the condensation chamber 101c has an upper chamber wall, and one end of the upper chamber wall close to the communication port 101b constructs the upper edge of the opening of the condensation chamber 101c. Optionally, one end of the upper chamber wall close to the communication port 101b extends above the communication port 101b. Considering that the humid and hot air coming out of the washing chamber 20 has a tendency to move upward, extending one end of the upper chamber wall close to the communication port 101b above the communication port 101b is beneficial for introducing the humid and hot air into the condensation chamber 101c, thereby improving the condensation efficiency of the condensation chamber 101c. Further optionally, the upper chamber wall also extends obliquely downward, so as to extend the length of the upper chamber wall on the one hand and increase the condensation capacity of the upper chamber wall, and on the other hand, the condensed water condensed on the upper chamber wall can flow downward along the upper chamber wall, thereby flowing back to the communication port 101b. In this embodiment, optionally, the inner wall surface of the upper chamber wall is arranged in a downwardly convex arc shape to further increase the area of its condensation surface.

[0043] In the present invention, further, the communication port 101b is located in the middle or lower part of the air chamber 101, and the air chamber 101 is also provided with a steam channel 101d connecting the communication port 101b and the upper part of the air chamber 101; it can be understood that the steam channel 101d itself can provide a condensation effect for the humid and hot air, which is beneficial for the recovery of water and heat energy. Optionally, the communication port 101b is located in the middle or lower part of the air chamber 101; it can be understood that arranging the communication port 101b in the middle or lower part of the air chamber 101 can enable the air chamber 101 to have a larger space to accommodate the humid and hot air, which is beneficial for the condensation of the humid and hot air.

[0044] Further, at least a part of the steam channel 101d is arranged to extend in a bent manner. It can be understood that the bent extension is beneficial for extending the length of the steam channel 101d, thereby increasing the condensation capacity of the steam channel 101d, enabling the humid and hot air to be well condensed in the steam channel 101d, and the condensed water after condensation can directly flow back from the steam channel 101d to the communication port 101b, and then flow back to the washing chamber 20.

[0045] Optionally, the channel portion of the steam channel 101d adjacent to the communication port 101b is inclined and extends downward. In this way, at the same height, the channel length of this part can be extended, thereby increasing the condensation travel of this part and improving its condensation ability for humid and hot air, so as to be more conducive to recovering the water and heat energy of the humid and hot air entering the steam channel. Further optionally, the channel portion of the steam channel 101d adjacent to the communication port 101b is bent and extended in a downward concave arc form. On the one hand, it can further extend the channel length of this part, and on the other hand, it is conducive to the condensed water condensed in this part flowing back to the communication port 101b and flowing back to the washing chamber 20 through the communication port 101b.

[0046] In the present invention, further, a water storage chamber 102 is further defined in the housing 10, and the upper part of the air chamber 101 is communicated with the upper part of the water storage chamber 102; thus, the humid and hot air gathered in the upper part of the air chamber 101 can also enter the water storage chamber 102 and transfer heat to the stored water in the water storage chamber 102, thereby further improving the heat energy recovery ability of the respirator 1. After the water temperature in the water storage chamber 102 is increased, it will be input into the washing chamber 20 in the next washing program, which can reduce the time required to heat the water during the washing process and reduce the energy consumption of the dishwasher.

[0047] Further, a water inlet channel 103 is further defined in the housing 10, and the air chamber 101 and the water storage chamber 102 are respectively arranged on opposite sides of the water inlet channel 103; thus, the water inlet channel 103 also has the function of separating the air chamber 101 and the water storage chamber 102. Optionally, at least part of the steam channel 101d shares a channel wall with the water inlet channel 103; thus, the humid and hot air in the steam channel 101d can also be transferred to the water in the water inlet channel 103 through the shared channel wall, so that the heat of the humid and hot air in the steam channel 101d can be absorbed and recovered by the water in the water inlet channel 103. Optionally, at least part of the part where the water inlet channel 103 shares a channel wall with the steam channel 101d protrudes towards the air chamber 101; thus, while increasing the volume of the water storage chamber 102, the length of the part where the water inlet channel 103 shares a channel wall with the steam channel 101d can be increased, so as to better transfer the heat of the humid and hot air in the steam channel 101d to the water in the water inlet channel 103, thereby improving the heat recovery efficiency of the humid and hot air.

[0048] In this embodiment, further, the water storage cavity 102 is provided with a first water inlet 102a and a first water outlet 102b. The first water inlet 102a is used to connect to the water outlet end of the water softener, and the first water outlet 102b is used to communicate with the washing cavity 20. Without loss of generality, the water softener has a salt cavity and a resin cavity. The salt cavity is provided with regenerated salt or a high-concentration salt solution, and the resin cavity is provided with water softening resin to adsorb calcium and magnesium ions in the water flowing into the resin cavity, so as to soften the water entering the resin cavity. The softened water can reduce the probability of forming scale; during the operation of the water softener, it is necessary to regularly introduce regenerated water into the salt cavity. The regenerated water introduced into the salt cavity forms a regenerated salt solution. When the softening performance of the water softening resin in the resin cavity decreases and the water softening resin needs to be restored, the regenerated salt solution formed in the salt cavity enters the resin cavity to restore and regenerate the water softening resin. In this embodiment, the first water inlet 102a is connected to the water outlet of the resin cavity of the water softener, that is, the water entering the water storage cavity 102 is softened by the water softener, which can reduce the probability of forming scale in the water storage cavity 102, and can also make the water introduced into the washing cavity 20 softened, thus avoiding the formation of scale in the washing cavity 20 and improving the washing effect. In addition, storing the softened water in the water storage cavity 102 and introducing it into the washing cavity 20 when needed does not require the water softener to soften it again, avoiding heat loss during the softening process. In this embodiment, optionally, the first water outlet 102b is provided with a control valve 102c. By reasonably controlling the opening and closing of the control valve 102c, for example, in any washing program, after the water storage cavity 102 finishes delivering water to the washing cavity 20, the control valve 102c closes, and the first water inlet 102a continues to supply water until the water stored in the water storage cavity 102 reaches the preset water level to pre-store water for the next washing program, thereby saving the water inlet time for the next program.

[0049] Further, the water inlet channel 103 includes a water inlet section 1031 and a water outlet section 1032. The lower end of the water inlet section 1031 is provided with a second water inlet 103a for connecting to raw water (i.e., tap water). The upper end of the water inlet section 1031 is connected to the upper end of the water outlet section 1032. The lower end of the water outlet section 1032 is provided with a second water outlet 103b for connecting to the water inlet end of the water softener. It should be noted that in this embodiment, the second water outlet 103b is connected to the water inlet end of the resin cavity of the water softener. In this embodiment, the water inlet channel 103 not only includes the upwardly extending water inlet section 1031, but also includes the downwardly extending water outlet section 1032, greatly extending its channel length, increasing the ability of the water inlet channel 103 to absorb the heat inside and around the respirator 1 (mainly the body 2 of the dishwasher), providing water with a higher temperature than the raw water for the water softener, reducing the energy consumption required for further heating inside the dishwasher, and thus reducing the energy consumption of the dishwasher.

[0050] Without loss of generality, in this embodiment, the air chamber 101 is located on the side of the water inlet section 1031 away from the water storage chamber 102, and the water storage chamber 102 is located on the side of the water outlet section 1032 away from the air chamber 101. An anti-siphon structure is provided between the upper ends of the water outlet section 1032 and the water inlet section 1031. The anti-siphon structure is provided with a water inlet ventilation port 103c communicating with the upper part of the water storage chamber 102. The water inlet ventilation port 103c can communicate with the air chamber 101 through the connection between the water storage chamber 102 and the air chamber 101, and then communicate with the outside atmosphere. When the water supply to the water inlet channel 103 stops, a negative pressure is formed upstream of the water inlet channel 103, causing the water retained in the downstream of the water inlet channel 103 to tend to flow back due to siphon. Since the water inlet ventilation port 103c is communicated with the atmosphere, the air in the atmosphere can enter the water inlet channel 103 through the water inlet ventilation port 103c to balance the pressure difference in the water inlet channel 103 and prevent the siphon phenomenon from occurring in the water inlet channel 103. Optionally, the anti-siphon structure includes a bent channel section 1033 and a rotary channel section 1034. The bent channel section 1033 protrudes upward. One end of the bent channel section 1033 is communicated with the upper end of the water inlet section 1031. The rotary channel section 1034 is arranged side by side below the bent channel section 1033. One end of the rotary channel section 1034 is communicated with the other end of the bent channel section 1033. The other end of the rotary channel section 1034 is communicated with the water outlet section 1032. The water inlet ventilation port 103c is provided on the rotary channel section 1034, and the water inlet ventilation port 103c is usually arranged in a slit shape.

[0051] In the present invention, further, the steam channel 101d includes a first steam channel section d1 and a second steam channel section d2 connected in sequence in the direction away from the communication port 101b. The channel width of the second steam channel section d2 is smaller than the channel width of the first steam channel section d1. It can be understood that in this embodiment, the connection between the first steam channel section d1 and the second steam channel section d2 is narrowed. When the humid and hot air passes through the narrowed connection, a squeezing effect will be generated, thereby improving the efficiency of condensing the humid and hot air, and further improving the recovery efficiency of water and heat energy.

[0052] Furthermore, a drainage channel 104 and a balanced air pressure channel 1041 communicating with the drainage channel 104 are further defined within the housing 10; a condensate sub-channel d11 and a steam passage d12 that are both parallel to the balanced air pressure channel 1041 are defined by the first steam channel section d1. The steam passage d12 communicates the communication port 101b and the second steam channel section d2. The lower end of the condensate sub-channel d11 communicates with the communication port 101b, and the upper end communicates with the balanced air pressure channel 1041 through a one-way valve 1042. The conduction direction of the one-way valve 1042 is from the condensate sub-channel d11 towards the balanced air pressure channel 1041. Without loss of generality, in this embodiment, the drainage channel 104 is provided with a sewage inlet 104a and a sewage outlet 104b. Among them, the sewage inlet 104a is used to communicate with the washing chamber 20, and the sewage outlet 104b is adapted to communicate with the sewer. The drainage process of the dishwasher is as follows: the washing sewage generated in the washing chamber 20 enters the drainage channel 104 through the sewage inlet 104a, and then is discharged into the sewer through the sewage outlet 104b, thereby realizing the drainage process of the dishwasher. When the drainage process stops, a negative pressure will be formed in the upstream section of the drainage channel 104, causing the water retained in the downstream section of the drainage channel 104 communicating with the sewer to have a tendency to flow back due to siphonage. Since the atmosphere can communicate with the balanced air pressure channel 1041 through the breathing port 101a, the condensate sub-channel d11, and the one-way valve 1042, the air in the atmosphere can enter the drainage channel 104 through the balanced air pressure channel 1041 to balance the pressure difference in the drainage channel 104 and prevent the drainage channel 104 from experiencing siphonage. Thus, it can prevent the water in the drainage channel 104 from flowing back into the washing chamber 20 after drainage and ensure the smooth discharge of the water retained in the drainage channel 104. It should be noted that in this embodiment, the condensate sub-channel d11 not only serves to connect the atmosphere with the balanced air pressure channel 1041 but also provides the function of condensing and absorbing heat for the rising humid and hot air, thereby improving the efficiency of condensing the humid and hot air and further improving the recovery efficiency of water and heat energy.

[0053] It can be understood that the steam passage d12 and the condensate sub-channel d11 are generally arranged in parallel. Optionally, both the condensate sub-channel d11 and the steam passage d12 extend obliquely upward. In this way, at the same height, the channel lengths of the condensate sub-channel d11 and the steam passage d12 can be extended, thereby increasing the condensation travel of the condensate sub-channel d11 and the steam passage d12, improving their condensation ability for humid and hot air, and being more conducive to recovering the water and heat energy of the humid and hot air entering the steam channel. Further optionally, both the condensate sub-channel d11 and the steam passage d12 are arranged in a concave arc shape. On the one hand, it can further extend the channel lengths of the condensate sub-channel d11 and the steam passage d12. On the other hand, it is conducive to the condensed water condensed by the condensate sub-channel d11 and the steam passage d12 to flow back to the communication port 101b and then flow back to the washing chamber 20 through the communication port 101b.

[0054] In the present invention, further, the breathing port 101a is located below the communication port 101b. In this way, on the one hand, due to the light weight characteristic of the humid and hot air, it has a tendency to move upward. Therefore, most of the humid and hot air entering the respirator 1 from the communication port 101b cannot move to the breathing port 101a and be discharged from the respirator 1, but will move upward to the upper part of the air chamber 101 and be condensed in the upper part of the air chamber 101 to recover the water and heat energy in this part of the humid and hot air, so as to keep the dishwasher warm and energy-saving. On the other hand, due to the action of its own gravity, dirt and static foreign objects entering from the breathing port 101a cannot reach the communication port 101b, so that no dirt and static foreign objects will enter the washing chamber 20.

[0055] Further, the air chamber 101 is also provided with a breathing channel 101e communicating the breathing port 101a and the communication port 101b. The breathing channel 101e includes a first channel segment e1 adjacent to the communication port 101b. The first channel segment e1 extends in the vertical direction, and the lower end of the first channel segment e1 is adjacent to the communication port 101b. In this way, a small amount of humid and hot air moving toward the breathing port 101a can recover the water and heat energy in this part of the humid and hot air under the condensation action of the channel wall of the first channel segment e1, so as to further improve the heat preservation and energy-saving ability of the dishwasher and thus reduce the energy consumption of the dishwasher.

[0056] In this embodiment, optionally, the first channel section e1 extends obliquely upward; in this way, the channel length of the first channel section e1 with the same height can be extended, thereby increasing the condensation stroke of the first channel section e1, improving the condensation ability of the first channel section e1 for humid and hot air, and being more conducive to recovering the water and heat energy of the humid and hot air entering the breathing channel 101e. Further optionally, the first channel section e1 is arranged in a concave arc shape. On the one hand, it can further extend the channel length of the first channel section e1, and on the other hand, it is conducive to the condensed water condensed on the channel wall of the first channel section e1 far from the communication port 101b to flow back to the communication port 101b and then flow back to the washing chamber 20 through the communication port 101b.

[0057] Optionally, the breathing channel 101e further includes a second channel section e2 extending downward from top to bottom, and the middle position of the first channel section e1 is communicated with the second channel section e2. It can be understood that in most cases, the first channel section e1 cannot recover all the water and heat in the humid and hot air entering the breathing channel 101e, that is, the air entering the second channel section e2 still carries heat and water. In this embodiment, the humid and hot air leaking into the second channel section e2 will gather at the upper end of the second channel section e2 to condense condensed water at the upper end of the second channel section e2, and part of these condensed water can flow back to the communication port 101b from the first channel section e1, thereby further recovering the condensed water and heat energy.

[0058] Further, the breathing channel 101e further includes a third channel section e3 extending downward from top to bottom. The upper end of the third channel section e3 is communicated with the lower end of the second channel section e2, and the breathing port 101a is provided at the lower end of the third channel section e3. In this embodiment, the third channel section e3 extends downward from the lower end of the second channel section e2, and the lower end of the third channel section e3 extends downward beyond the lower side of the communication port 101b. Setting the breathing port 101a at the lower end of the third channel section e3 is conducive to making the breathing port 101a located below the communication port 101b. Optionally, the channel width of the third channel section e3 is greater than the channel width of the second channel section e2; it can be understood that the larger the channel width, the larger the space of the channel, and the larger channel space is conducive to the air flow breathing exchange at the breathing port 101a.

[0059] Further, an insect-proof structure 101g is provided in the third channel section e3 to limit insects such as cockroaches from entering the communication port 101b through the breathing channel 101e through the insect-proof structure 101g, thereby restricting insects such as cockroaches from entering the washing chamber 20 through the breathing port 101a.

[0060] Furthermore, the insect-proof structure 101g includes a plurality of insect-proof ribs g1 spaced apart in the extending direction of the third channel section e3. It can be understood that the setting of the insect-proof ribs g1 can block insects such as cockroaches and prevent them from passing through the breathing channel 101e; in addition, the structure of the insect-proof ribs g1 is simple and easy to prepare and implement. Of course, in other embodiments, the insect-proof structure 101g may further include other structures such as an insect-proof net disposed in the third channel section e3.

[0061] For the technical solution of arranging a plurality of insect-proof ribs g1, further, one end of the insect-proof rib g1 is connected to the channel side wall of the third channel section e3, and there is a gap between the other end and the channel side wall of the third channel section e3 to form a breathing gap; and, in the extending direction of the third channel section e3, any two adjacent insect-proof ribs g1 are arranged in a staggered manner. In this way, if insects such as cockroaches want to pass through the plurality of insect-proof ribs g1, they need to constantly change their crawling directions, which can effectively increase the difficulty for insects such as cockroaches to pass through.

[0062] Further, among any three adjacent insect-proof ribs g1, one end of the middle insect-proof rib g1 close to the breathing gap extends into the space formed by the other two insect-proof ribs g1, so that the insect-proof structure 101g formed by the plurality of insect-proof ribs g1 is more confusing and can increase the difficulty for insects such as cockroaches to pass through the breathing channel 101e.

[0063] Further, the cross-section of the third channel section e3 perpendicular to its extending direction is rectangular, and one end and both sides of the insect-proof rib g1 are connected to the channel wall of the breathing channel 101e; in this way, on the one hand, all gaps except the breathing gap are eliminated, which can reduce the probability of insects such as cockroaches passing through the breathing channel 101e, and on the other hand, it is also beneficial to enhance the structural strength of the third channel section e3. It can be understood that being rectangular here means that the third channel section e3 is generally flat and has four side walls, and the four side walls enclose the channel side wall, and the insect-proof rib g1 is connected to three of the side walls and is at a certain distance from the remaining side wall.

[0064] Further, one end of the insect-proof rib g1 close to the breathing gap extends obliquely away from the breathing port 101a. In this way, on the one hand, the length of a single insect-proof rib g1 can be extended, which is beneficial to extending the effective length that insects such as cockroaches need to pass through; on the other hand, for the obliquely extending insect-proof rib g1, when insects such as cockroaches pass through, there is a downward sliding trend, which is not conducive to insects such as cockroaches to stand firm, so as to further increase the difficulty for insects such as cockroaches to pass through.

[0065] Further, the width w2 of at least one breathing gap is smaller than the width w1 of the breathing port 101a (see Figure 4) Thus, even if some insects pass through the breathing port 101a, they cannot pass through the smaller breathing gaps, and thus cannot enter the communication port 101b. Optionally, the width of each breathing gap is smaller than the width of the breathing port 101a. Generally, at least the width of the breathing gap close to the breathing port 101a is smaller than the width of the breathing port 101a. Further, the width of the breathing gap gradually decreases in the direction away from the breathing port 101a; it can be understood that the gradual decrease here means that for any two adjacent breathing gaps, the width of the breathing gap farther from the breathing port 101a is smaller than the width of the breathing gap closer to the breathing port 101a, so as to gradually limit the passage of insects of different sizes and avoid a large number of insects blocking at one breathing gap, which affects the breathing smoothness of the respirator 1.
