a housing 10 defining an air chamber 101 therein, the air chamber 101 being provided with a breathing port 101a for communicating with the atmosphere, a communication port 101b for communicating with the washing chamber 20, and a condensation chamber 101c adjacent to the communication port 101 b;

the condensation chamber 101c is not lower than the lower edge of the communication port 101b, and the condensation chamber 101c opens toward the communication port 101 b.

According to the technical scheme, the condensation cavity 101c with the opening facing the communication port 101b is additionally arranged, so that the leakage of damp and hot air can be reduced through the condensation cavity 101c, meanwhile, a plurality of cavity walls of the condensation cavity 101c can provide condensation, the condensation efficiency is high, heat energy in the damp and hot air can be well recovered, condensed water condensed through the condensation cavity 101c can flow back to the communication port 101b through the opening of the condensation cavity and flow back to the washing cavity 20 through the communication port 101b, the recovery of the condensed water is realized, the heat preservation and the energy saving of the dish washing machine can be realized, and the energy consumption of the dish washing machine is reduced.

Optionally, the lower cavity wall extends obliquely downwards; therefore, on one hand, the length of the lower cavity wall can be prolonged, the condensation capacity of the lower cavity wall is increased, and on the other hand, the condensed water condensed out from the condensation cavity 101c flows back to the communication port 101 b.

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

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 further provided with a steam passage 101d for communicating the communication port 101b with the upper part of the air chamber 101; it will be appreciated that the steam channel 101d itself can provide condensation for the hot and humid air, facilitating 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 is understood that the communication port 101b is provided at the middle or lower portion of the air chamber 101, so that the air chamber 101 can have a larger space for accommodating hot and humid air to facilitate the condensation of the hot and humid air.

Further, the steam channel 101d is at least partially disposed in a bent and extended manner. It can be understood that the bending and extending arrangement is beneficial to extending the length of the steam channel 101d, so as to increase the condensation capacity of the steam channel 101d, so that the hot, humid and hot air can be condensed well in the steam channel 101d, and the condensed water can directly flow back from the steam channel 101d to the communication port 101b and then flow back to the washing chamber 20.

Alternatively, the channel part of the steam channel 101d adjacent to the communication port 101b is inclined downward, so that the channel length of the channel part can be extended at the same height, thereby increasing the condensation stroke of the channel part, and improving the condensation capacity of the channel part on the hot and humid air, so as to be more beneficial to recovering the water and the heat energy of the hot and humid air entering the steam channel. Further optionally, a channel portion of the steam channel 101d, which is adjacent to the communication port 101b, is bent and extended in a downward-concave arc manner, so that on one hand, the channel length of the portion can be further extended, and on the other hand, condensed water condensed from the portion can be favorably returned to the communication port 101b and returned to the washing chamber 20 through the communication port 101 b.

In the present invention, further, a water storage cavity 102 is defined in the housing 10, and an upper portion of the air cavity 101 is communicated with an upper portion of the water storage cavity 102; therefore, the hot and humid air gathered at the upper part of the air chamber 101 can also enter the water storage chamber 102 and transfer the heat to the stored water in the water storage chamber 102, so as to further improve the heat energy recovery capability of the respirator 1, and after the water temperature stored in the water storage chamber 102 is raised, the water temperature can be input into the washing chamber 20 in the next washing program, thereby reducing the time for heating the water in the washing process and reducing the energy consumption of the dishwasher.

Optionally, the steam channel 101d at least partially shares a channel wall with the water inlet channel 103; in this way, the hot and humid air in the steam channel 101d can be transferred to the water in the water inlet channel 103 through the shared channel wall, so that the heat of the hot and humid air in the steam channel 101d can be recovered by absorbing the heat through the water in the water inlet channel 103. Optionally, at least a part of the common channel wall between the water inlet channel 103 and the steam channel 101d protrudes toward the air cavity 101; in this way, the volume of the water storage cavity 102 can be increased, and the length of the portion of the common channel wall between the water inlet channel 103 and the steam channel 101d can be increased, so that the heat of the hot and humid air in the steam channel 101d can be better transferred to the water in the water inlet channel 103, and the heat recovery efficiency of the hot and humid air can be improved.

In this embodiment, further, the water storage chamber 102 is provided with a first water inlet 102a and a first water outlet 102b, the first water inlet 102a is configured to be connected to the water outlet end of the water softener, and the first water outlet 102b is configured to communicate with the washing chamber 20. Without loss of generality, the water softener is provided with a salt cavity and a resin cavity, wherein regenerated salt or high-concentration salt solution is arranged in the salt cavity, soft water resin is arranged in the resin cavity to adsorb calcium, magnesium ions and the like in water flowing into the resin cavity so as to soften the water entering the resin cavity, and the softened water can reduce the probability of forming water scale; need regularly to let in the regeneration water to the salt chamber in the course of the work of water softener, the regeneration water that lets in the salt intracavity forms regeneration salt solution, and when the softening performance of the soft water resin of resin intracavity reduced, when needing to reduce soft water resin, the regeneration salt solution of formation in the salt intracavity got into the resin chamber, and the soft water resin is reduced and is regenerated. In this embodiment, the first water inlet 102a is connected to a 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, so that the probability of forming scale in the water storage cavity 102 can be reduced, the water introduced into the washing cavity 20 is softened, the formation of scale in the washing cavity 20 is avoided, and the washing effect can be improved. In addition, the softened water is stored in the water storage cavity 102 and is introduced into the washing cavity 20 when needed, and the process does not need the water softener to soften again, so that the heat is prevented from being dissipated in the softening process. In this embodiment, optionally, the first water outlet 102b is provided with a control valve 102c, and by reasonably controlling the opening and closing of the control valve 102c, for example, in any washing procedure, after the water storage cavity 102 finishes delivering water to the washing cavity 20, the control valve 102c is closed, and the first water inlet 102a continues to feed water until the stored water in the water storage cavity 102 reaches a preset water level, so as to pre-store water for the next washing procedure, thereby saving the water feeding time of the next procedure.

Further, the water inlet passage 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 being connected with raw water (i.e., tap water), the upper end of the water inlet section 1031 is connected with the upper end of the water outlet section 1032, and the lower end of the water outlet section 1032 is provided with a second water outlet 103b for being connected with the water inlet end of the water softener. In this embodiment, the second water outlet 103b is connected to the water inlet end of the resin chamber of the water softener. In this embodiment, the water inlet passage 103 includes not only the upwards extending water inlet section 1031, but also the downwards extending water outlet section 1032, so as to greatly prolong the length of the passage, increase the ability of the water inlet passage 103 to absorb the heat of the inside and the periphery (mainly the body 2 of the dishwasher) of the respirator 1, provide water with a higher temperature than the raw water for the water softener, reduce the energy consumption required for further heating in the dishwasher, and reduce the energy consumption of the dishwasher.

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, 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 arranged between the upper end of the water outlet section 1032 and the upper end of the water inlet section 1031, a water inlet vent 103c communicated with the upper portion of the water storage chamber 102 is arranged on the anti-siphon structure, and the water inlet vent 103c can be communicated with the air chamber 101 through a communication position between the water storage chamber 102 and the air chamber 101, and further communicated with the external atmosphere. When the water supply into the water inlet channel 103 is stopped, negative pressure is formed at the upstream of the water inlet channel 103, so that water retained in the downstream of the water inlet channel 103 tends to flow back due to siphon, and air in the atmosphere can enter the water inlet channel 103 through the water inlet vent 103c due to the fact that the water inlet vent 103c is communicated with the atmosphere, so that the pressure difference in the water inlet channel 103 is balanced, and the siphon phenomenon of the water inlet channel 103 is prevented. Optionally, the anti-siphon structure includes bending channel section 1033 and gyration channel section 1034, bending channel section 1033 upwards protrudes, bending channel section 1033's one end with the upper end intercommunication of the section 1031 of intaking, gyration channel section 1034 sets up side by side the below of bending channel section 1033, gyration channel section 1034's one end with bending channel section 1033's the other end intercommunication, gyration channel section 1034's the other end with go out water section 1032 intercommunication, be equipped with on gyration channel section 1034 intake vent 103c, intake vent 103c is the slit setting usually.

In the present invention, further, the steam passage 101d includes a first steam passage section d1 and a second steam passage section d2 connected in series in a direction away from the communication port 101b, and a passage width of the second steam passage section d2 is smaller than a passage width of the first steam passage section d 1. It can be understood that, in the present embodiment, the connection between the first steam passage section d1 and the second steam passage section d2 is narrowed, and when the hot and humid air passes through the narrowed connection, a squeezing effect is generated, so that the efficiency of condensing the hot and humid air is improved, and the recovery efficiency of water and heat energy is improved.

Further, a drainage channel 104 and a balance air pressure channel 1041 communicated with the drainage channel 104 are defined in the shell 10; the first steam passage section d1 defines a condenser sub-passage d11 and a steam passage d12 both extending parallel to the equilibrium air pressure passage 1041, the steam passage d12 communicates with the communication port 101b and the second steam passage section d2, the lower end of the condenser sub-passage d11 communicates with the communication port 101b, the upper end of the condenser sub-passage communicates with the equilibrium air pressure passage 1041 through a check valve 1042, and the check valve 1042 is communicated from the condenser sub-passage d11 to the equilibrium air pressure passage 1041. Without loss of generality, in this embodiment, the drainage channel 104 is provided with a sewage inlet 104a and a sewage outlet 104b, wherein the sewage inlet 104a is adapted to communicate with the washing chamber 20 and the sewage outlet 104b is adapted to communicate with a sewer. The drainage process of the dishwasher is as follows: the washing-sewage generated in the washing chamber 20 enters the drain passage 104 through the sewage inlet 104a and is then discharged to the sewage through the sewage outlet 104b, thereby performing a draining process of the dishwasher. When the drainage process is stopped, negative pressure will be formed in the upstream section of the drainage channel 104, so that water retained in the downstream section of the drainage channel 104 communicated with a sewer has a tendency of flowing back due to siphon, and since the atmosphere can be communicated with the equilibrium air pressure channel 1041 through the breathing port 101a, the condensation sub-channel d11 and the one-way valve 1042, air in the atmosphere can enter the drainage channel 104 through the equilibrium air pressure channel 1041 to balance the pressure difference in the drainage channel 104, preventing the drainage channel 104 from siphoning, thereby preventing the water in the drainage channel 104 from flowing back into the washing chamber 20 after drainage, and ensuring that the water retained in the drainage channel 104 is smoothly drained. In this embodiment, the condensation sub-passage d11 not only has the function of communicating the atmosphere with the equilibrium air pressure passage 1041, but also has the function of providing condensation heat absorption for the rising hot and humid air, thereby improving the efficiency of condensing the hot and humid air and further improving the recovery efficiency of water and heat energy.

It will be appreciated that the steam passageway d12 is generally disposed in parallel with the condensation sub-passageway d 11. Optionally, the condensation sub-channel d11 and the steam passageway d12 are both disposed to extend obliquely upward, so that at the same height, the channel lengths of the condensation sub-channel d11 and the steam passageway d12 can be lengthened, thereby increasing the condensation strokes of the condensation sub-channel d11 and the steam passageway d12, and improving the condensation capacity of the condensation sub-channel d11 and the steam passageway d12 to facilitate the recovery of water and heat energy of the hot and humid air entering the steam passageway. Further alternatively, the condensation sub-channel d11 and the steam passageway d12 are both in a concave arc shape, so that on one hand, the channel lengths of the condensation sub-channel d11 and the steam passageway d12 can be further extended, and on the other hand, the condensed water condensed out from the condensation sub-channel d11 and the steam passageway d12 can be facilitated to flow back to the communication port 101b and flow back to the washing chamber 20 through the communication port 101 b.

In the present invention, further, the breathing port 101a is located below the communication port 101 b; in this way, on one hand, due to the light weight property of the hot and humid air, the hot and humid air entering the respirator 1 from the communication port 101b cannot move to the breathing port 101a and then is discharged out of the respirator 1, but moves upwards to the upper part of the air chamber 101 and condenses at the upper part of the air chamber 101 to recover the water and heat energy in the hot and humid air, so that the dishwasher is kept warm and energy-saving, and on the other hand, the dirt and static foreign matters entering from the breathing port 101a cannot reach the communication port 101b due to the self gravity, so that no dirt and static foreign matters enter the washing chamber 20.

Further, the air chamber 101 is further provided with a breathing passage 101e for communicating the breathing port 101a and the communication port 101 b; the breathing passage 101e includes a first passage section e1 adjacent to the communication port 101b, the first passage section e1 extends in the up-down direction, and the lower end of the first passage section e1 is adjacent to the communication port 101 b; in this way, a small amount of hot and humid air moving towards the breathing opening 101a can be condensed by the channel wall of the first channel section e1, and water and heat energy in the hot and humid air can be recovered, so as to further improve the heat preservation and energy saving capability of the dishwasher, and further reduce the energy consumption of the dishwasher.

In this embodiment, optionally, the first channel section e1 extends obliquely upward; in this way, the channel length of the first channel segment e1 with the same height can be prolonged, so that the condensation stroke of the first channel segment e1 is increased, and the condensation capacity of the first channel segment e1 on the hot and humid air is improved, so as to be more beneficial to recovering the water and the heat energy of the hot and humid air entering the breathing channel 101 e. Further alternatively, the first channel segment e1 is in a concave arc shape, which can further extend the channel length of the first channel segment e1, and can facilitate the condensed water condensed on the channel wall of the first channel segment e1 away from the communication port 101b to flow back to the communication port 101b and flow back to the washing chamber 20 through the communication port 101 b.

Optionally, the breathing passage 101e further comprises a second passage section e2 extending from top to bottom, and the first passage section e1 is communicated with the middle position of the second passage section e 2. It will be appreciated that in most cases the first channel section e1 will not be able to recover all the water and heat from the hot and humid air entering the breathing channel 101e, i.e. the air entering the second channel section e2 will still carry heat and water. In this embodiment, the hot and humid air leaking to the second passage section e2 is collected at the upper end of the second passage section e2 to condense out condensed water at the upper end of the second passage section e2, and the condensed water can be partially returned from the first passage section e1 to the communication port 101b, thereby further recovering the condensed water and the heat.

Further, the breathing passage 101e further includes a third passage section e3 extending from top to bottom, an upper end of the third passage section e3 is communicated with a lower end of the second passage section e2, and the lower end of the third passage section e3 is provided with the breathing opening 101 a. In this embodiment, the third channel segment e3 extends downward from the lower end of the second channel segment e2, and the lower end of the third channel segment e3 extends downward beyond the lower side of the communication port 101b, and the breathing port 101a is disposed at the lower end of the third channel segment e3, which is favorable for positioning the breathing port 101a at the lower side of the communication port 101 b. Optionally, the channel width of the third channel segment e3 is greater than the channel width of the second channel segment e 2; it will be appreciated that the larger the channel width, the larger the channel space, and the larger the channel space is for facilitating the exchange of airflow breath at the breathing opening 101 a.

Further, an insect prevention structure 101g is arranged in the third channel segment e3, so that the insect prevention structure 101g can limit the insects such as cockroaches from entering the communication opening 101b through the breathing channel 101e, and the insects such as cockroaches can be limited from entering the washing chamber 20 through the breathing opening 101 a.

Further, the insect-proof structure 101g includes a plurality of insect-proof ribs g1 arranged at intervals in the extending direction of the third channel segment e 3. It can be understood that the pest prevention blocking rib g1 can block insects such as cockroaches and prevent the insects such as the cockroaches from passing through the breathing channel 101 e; in addition, the insect-proof rib g1 is simple in structure 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 segment e 3.

For the technical scheme of arranging a plurality of insect-proof blocking ribs g1, further, one end of the insect-proof blocking rib g1 is connected with the channel side wall of the third channel segment e3, and a gap is formed between the other end of the insect-proof blocking rib g1 and the channel side wall of the third channel segment e3 to form a breathing gap; in addition, in the extending direction of the third channel segment e3, any two adjacent insect-proof blocking ribs g1 are arranged in a staggered manner, so that the crawling direction of insects such as cockroaches needs to be changed continuously if the insects such as cockroaches pass through the multiple insect-proof blocking ribs g1, and the passing difficulty of the insects such as cockroaches can be effectively improved.

Furthermore, in the three arbitrary adjacent protection against insects muscle g1, be located the protection against insects muscle g1 in the middle of being close to the breathing gap one end stretch into the remaining two protection against insects muscle g1 forms in the space to make the protection against insects structure 101g that a plurality of protection against insects muscle g1 formed more have the puzzlement nature, can increase the difficulty that insects such as cockroaches pass through breathing passageway 101 e.

Further, the cross section of the third channel segment e3 perpendicular to the extending direction thereof is rectangular, and one end and two sides of the insect-proof blocking rib g1 are connected with the channel wall of the breathing channel 101 e; therefore, on one hand, all gaps except the breathing gap are eliminated, the probability that insects such as cockroaches pass through the breathing channel 101e can be reduced, and on the other hand, the structural strength of the third channel segment e3 is enhanced. It is understood that the rectangular shape here means that the third channel section e3 is substantially flat and has four side walls, the four side walls surround the channel side walls, and the vermin-proof barrier rib g1 is connected to three of the side walls at a distance from the remaining side walls.

Furthermore, one end of the insect-proof blocking rib g1 close to the breathing gap extends obliquely in a direction away from the breathing opening 101a, so that the length of the single insect-proof blocking rib g1 can be increased, and the effective length of the insects such as cockroaches to pass through is increased; on the other hand, when insects such as cockroaches pass through the obliquely extending insect-proof blocking rib g1, the insect-proof blocking rib tends to slide downwards, so that the insect-proof blocking rib is not beneficial to standing of the insects such as cockroaches, and the difficulty of the insects such as cockroaches in passing is further improved.

Further, the width w2 of at least one of the breathing gaps is smaller than the width w1 of the breathing opening 101a (see fig. 4); even if some insects pass through the breathing port 101a, they cannot pass through the small breathing gap and cannot enter the communication port 101 b. Optionally, the width of each breathing gap is smaller than the width of the breathing opening 101 a. Typically, at least, the width of the breathing gap near the breathing opening 101a is smaller than the width of the breathing opening 101 a. Further, the width of the breathing gap gradually decreases from the direction away from the breathing opening 101 a; it is understood that, gradually decreasing here means that for any two adjacent breathing gaps, the width of the breathing gap farther than the breathing opening 101a is smaller than the width of the breathing gap closer than the breathing opening 101a, so as to gradually limit the passage of insects with different volume sizes, and prevent a large amount of insects from blocking one breathing gap and affecting the breathing smoothness of the respirator 1.
