In the present invention, further, a water passage 105b communicating the water storage chamber 102 with the upper end of the regeneration water chamber 105 is defined in the housing 10. In this embodiment, in the process of injecting water into the water storage cavity 102, water can be injected into the regeneration water cavity 105 through the water passage 105b, so that when the soft water resin in the resin cavity needs to be reduced and regenerated, the regeneration water can be injected into the salt cavity of the water softener through the regeneration water outlet 105 a. In this embodiment, optionally, the water channel 105b is configured in a tunnel form, that is, the water channel 105b does not pass through the water outlet section 1032, but is formed in the shell of the housing 10 in a tunnel form and bypasses the water outlet section 1032, so as to avoid the water channel 105b from affecting the smoothness of the water outlet section 1032.

Further, an air passing channel 105c communicating the space between the water inlet section 1031 and the water outlet section 1032 with the water storage cavity 102 is defined in the housing 10, and the air passing channel 105c is located at the upper side of the water passing channel 105 b; in this way, during the water filling process of the water storage chamber 102, when the water flows through the water passage 105b to fill the regeneration water chamber 105 and then continues to rise, the water in the space above the regeneration water chamber 105 and the water in the water storage chamber 102 can rise simultaneously due to the air passage 105 c.

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. It can be understood that, since the sewage in the drainage channel 104 is usually at a high temperature, at least a portion of the water inlet channel 103 and the drainage channel 104 share the channel wall, so that the water in the water inlet channel 103 can be heated by the drainage channel 104 in a heat conduction manner during the process of draining the sewage, thereby recovering the heat energy in the high-temperature sewage and reducing the power consumption of the dishwasher. Of course, water is typically stored in the inlet passage 103.

Further, a balance air pressure passage 1041 communicated with the drainage passage 104 is further defined in the housing 10, a check valve 1042 is disposed between the balance air pressure passage 1041 and the air chamber 101, and a conduction direction of the check valve 1042 is from the air chamber 101 to the balance air pressure passage 1041; at least a portion of the water inlet passage 103 shares a passage wall with the equilibrium gas pressure passage 1041. In this embodiment, when the dishwasher stops the draining process, a negative pressure will be formed in the upstream section of the drainage channel 104, so that the water retained in the downstream section of the drainage channel 104 communicated with the sewer has a tendency of flowing back due to siphoning, and since the atmosphere can be communicated with the balanced air pressure channel 1041 through the breathing port 101a, the air chamber 101 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 siphoning, thereby preventing the water in the drainage channel 104 from flowing back into the washing chamber 20 after draining, and ensuring the water retained in the drainage channel 104 to be drained smoothly. In this embodiment, when the dishwasher drains water, there is a part of high temperature sewage that enters into the balanced air pressure passage 1041, so, at least part of the water inlet passage 103 and the balanced air pressure passage 1041 share the passage wall, so that the high temperature sewage that enters into the balanced air pressure passage 1041 can heat the water in the water inlet passage 103, thereby further recovering the heat energy in the high temperature sewage, and reducing the power consumption of the dishwasher.

In this embodiment, in order to facilitate the communication between the balanced air pressure passage 1041 and the air chamber 101, in a case where the air chamber 101 is adjacent to a side of the water inlet section 1031, optionally, the water drain passage 104 and the balanced air pressure passage 1041 are both located on a side of the water inlet section 1031 facing away from the water outlet section 1032. In this case, on the water inlet passage 103, sharing a passage wall with the water discharge passage 104 and/or the balanced air pressure passage 1041 is the water inlet section 1031; and when the air chamber 101 and the water storage chamber 102 are respectively arranged at the two opposite sides of the water inlet channel 103, the water inlet channel 103 and the water storage chamber 102 are respectively arranged at the two opposite sides of the water inlet channel 103, so that the space in the shell 10 is more reasonably utilized.

In this embodiment, optionally, a flow meter 1035 is disposed on the water inlet section 1031 to control the water inlet amount of the dishwasher. Further, the flow meter 1035 is located between a channel wall on the water inlet section 1031, which is shared with the water discharge channel 104, and a channel wall on the water inlet section 1031, which is shared with the balanced air pressure channel 1041, so that the structure of the part is compact and the space utilization is more reasonable.

In the present invention, the air chamber 101 is further provided with a condensation chamber 101c adjacent to the communication port 101b, the condensation chamber 101c is not lower than the lower edge of the communication port 101b, and the opening of the condensation chamber 101c faces the communication port 101b, so as to reduce the leakage of the moist and hot air through the condensation chamber 101c, and meanwhile, a plurality of chamber walls of the condensation chamber 101c can provide a condensation effect, so that the present invention has a high condensation efficiency, and can well recover the heat energy in the moist and hot air, and the condensed water condensed by the condensation chamber 101c can flow back to the communication port 101b through the opening and flow back to the washing chamber 20 through the communication port 101b, so as to realize the recovery of the condensed water, thereby enabling the dishwasher to preserve heat and save energy, and reducing the energy consumption of the dishwasher.

Further, the breathing port 101a is located on the lower side of 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 extending in the up-down direction; 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.
