[0041] The present invention provides a respirator, which is used 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.

[0042] Refer to Figures 1 to 4 , in an embodiment of the present invention, the respirator 1 includes:

[0043] A housing 10, an air cavity 101 and a water storage cavity 102 are defined inside the housing 10. The air cavity 101 is provided with a breathing port 101a for communicating with the atmosphere and a communication port 101b for communicating with the washing cavity 20. 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 for communicating with the water outlet end of a water softener, and the first water outlet 102b is used for communicating with the washing cavity 20.

[0044] In this embodiment, during operation, the washing cavity 20 of the dishwasher can be sequentially communicated with the atmosphere through the communication port 101b, the air cavity 101 and the breathing port 101a to achieve pressure balance inside the washing cavity 20.

[0045] It should be noted that the water outlet end of the water softener connected to the first water inlet 102a refers to the water outlet end of the resin chamber of the water softener, that is, the first water inlet 102a is communicated with the water outlet end of the resin chamber of the water softener. Generally, water softening resin is provided in the resin chamber of the water softener to adsorb calcium and magnesium ions and the like in the water flowing into the resin chamber, so as to soften the water entering the resin chamber, and the probability of forming scale can be reduced after softening. In addition, in this embodiment, the first water outlet 102b only needs to be communicated with the washing chamber 20, and the communication mode between the first water outlet 102b and the washing chamber 20 is not limited. For example, the communication can be achieved by additionally arranging a communication pipeline, or a water softener with an additional water delivery channel can be used, and the first water outlet 102b is communicated with the washing chamber 20 through this water delivery channel.

[0046] In the technical solution of the present invention, on the one hand, the water entering the water storage chamber 102 is softened by the water softener, which can reduce the probability of scale formation in the water storage chamber 102; on the other hand, by storing water in the water storage chamber 102 to absorb the heat dissipated by the body 2 of the dishwasher during operation, this part of heat can be recovered, thereby reducing the power consumption of the dishwasher; in addition, the softened water is stored in the water storage chamber 102 and introduced into the washing chamber 20 when needed, and in this process, it is no longer necessary for the water softener to soften again, avoiding heat dissipation during the softening process; it can be understood that the water temperature in the water storage chamber 102 can rise after absorbing heat, so as to reduce the energy consumption required for heating the water entering the interior of the dishwasher.

[0047] Further, the percentage of the volume of the water storage chamber 102 in the volume of the housing 10 is greater than or equal to 60%, that is, the water storage chamber 102 occupies most of the space in the housing 10 and has a relatively large volume, which can better absorb the heat dissipated by the body 2 of the dishwasher during operation. Further optionally, the percentage of the volume of the water storage chamber 102 in the volume of the housing 10 is greater than or equal to 65%. In addition, optionally, the volume of the water storage chamber 102 is greater than or equal to 2L and less than or equal to 3L, for example, but not limited to, set to 2.5L to adapt to the water consumption required for a single washing program of most dishwashers at present; however, this design is not limited thereto, and in other embodiments, the volume of the water storage chamber 102 can also be set to other sizes as long as it corresponds to the water consumption of a single washing program of the applied dishwasher.

[0048] Further, a control valve 102c is provided at the first water outlet 102b; in this way, by reasonably controlling the opening and closing of the control valve 102c, for example, in any washing program, after the water storage chamber 102 finishes delivering water to the washing chamber 20, the control valve 102c closes, and the first water inlet 102a continues to admit water until the water stored in the water storage chamber 102 reaches a preset water level, so as to pre-store water for the next washing program, thereby saving the water inlet time for the next program; of course, in other embodiments, there may be other control valve 102c control methods, as long as at least one washing program can pre-store water. Optionally, the control valve 102c is configured as an electric two-way valve driven by a wax motor, and such a control valve 102c has relatively low power consumption and cost; however, the present design is not limited thereto, and in other embodiments, the control valve 102c can also be configured as an electromagnetic two-way valve or the like.

[0049] In the present invention, further, the upper part of the air chamber 101 is communicated with the upper part of the water storage chamber 102; in this way, 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 water stored in the water storage chamber 102, thereby further improving the heat energy recovery ability of the breather 1, and 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.

[0050] Furthermore, the upper end of the water storage chamber 102 is provided with a water retaining rib 1021 extending in the transverse direction, and the end of the water retaining rib 1021 away from the air chamber 101 is provided with a pass; in this way, when the dishwasher is tilted due to displacement or transportation, and the respirator 1 is tilted, the water retaining rib 1021 can limit the water in the water storage chamber 102 as much as possible, reduce the amount of water overflowing from the upper part of the water storage chamber 102 to the air chamber 101, and flow into the washing chamber from the connecting port 101b, thereby reducing the probability of water leakage in the dishwasher. Without loss of generality, the pass is limited by the interval between the end of the water retaining rib 1021 and the side wall of the shell 10; however, the present design is not limited thereto, and in other embodiments, the pass can also be configured as a fracture on the water retaining rib 1021. Optionally, the water retaining rib 1021 extends downwardly and obliquely in a direction away from the air cavity 101; it can be understood that the hot and humid air entering the water storage cavity 102 from the air cavity 101 will condense at the upper part of the water storage cavity 102, thereby recovering the heat of the hot and humid air. Due to the downward inclined setting of the water retaining rib 1021, the condensed water can flow into the water stored in the water storage cavity 102, thereby better recovering the condensed water. In addition, after the respirator 1 tilts and causes some water to slightly overflow the water retaining rib 1021, when the respirator 1 is reset from the tilt, the slightly overflowed water can flow back into the water storage cavity 102 along the downward inclined water retaining rib 1021.

[0051] Furthermore, a first water passage 102d is provided between the water storage chamber 102 and the air chamber 101 on the upper side of the water retaining rib 1021; thus, after the water in the water storage chamber 102 overflows the water retaining rib 1021, it can flow into the air chamber 101 through the first water passage 102d, and flow into the washing chamber 20 from the connecting port 101b of the air chamber 101, so as to avoid the water in the water storage chamber 102 from having nowhere to drain and causing the water to burst when there is too much water in the water storage chamber 102. Optionally, the first water passage 102d is configured in the form of a tunnel, that is, the first water passage 102d is formed in the shell of the housing 10 in the form of a tunnel.

[0052] Furthermore, the connection between the upper part of the air chamber 101 and the upper part of the water storage chamber 102 (including the provision of the first water passage 102d) can also provide a new way for the water inlet of the washing chamber 20. Specifically, when the control valve 102c is closed, water can be introduced into the water storage chamber 102, so that the water flows into the air chamber 101 through the upper connection part (including the first water passage 102d), and then flows into the washing chamber 20 from the connection port 101b to complete the water inlet of the washing chamber 20. For example, in any washing program, after the normal water inlet and washing for a while, when it is detected that the water level in the washing chamber 20 is slightly low and there is a water shortage, or when it is necessary to further increase the water level in the washing chamber 20, the water can be introduced into the washing chamber 20 in this way. Another example is for a dishwasher with a quick wash function. After the normal water inlet in the quick wash program (the quick wash program usually only has one normal water inlet), when it is still necessary to introduce water into the washing chamber 20, it can be done in this way. Still another example is for some dishwashers. During the entire washing process, there are washing programs that only require a small amount of water inlet. When entering the water inlet process of this washing program that only requires a small amount of water inlet, the water can be introduced into the washing chamber 20 in this way. Of course, there can be other situations where this water inlet method can be utilized.

[0053] Furthermore, an inlet passage 103 is further defined within the housing 10. The inlet passage 103 is provided with a second water inlet 103a for connecting to raw water and a second water outlet 103b for connecting to the water inlet end of the water softener. The air chamber 101 and the water storage chamber 102 are respectively disposed on opposite sides of the inlet passage 103. It should be noted that the water inlet end of the water softener connected to the second water outlet 103b refers to the water inlet end of the resin chamber of the water softener, that is, the second water outlet 103b is communicated with the water inlet end of the resin chamber of the water softener. In this embodiment, the raw water can enter the inlet passage 103 through the second water inlet 103a, and then flow into the resin chamber of the water softener through the second water outlet 103b. After the water is softened by the resin chamber of the water softener, it is then introduced into the water storage chamber 102 from the first water inlet 102a, and finally introduced into the washing chamber 20 from the first water outlet 102b, thereby avoiding the formation of scale in the washing chamber 20 and improving the washing effect. It can be understood that the inlet passage 103 can also absorb the heat inside the respirator 1 and its surrounding area (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 reducing the energy consumption of the dishwasher. In addition, the inlet passage 103 also has the function of separating the air chamber 101 and the water storage chamber 102.

[0054] Furthermore, at least a part of the water inlet channel 103 protrudes towards the air chamber 101; in this way, on the one hand, the volume of the water storage chamber 102 can be increased, and on the other hand, the length of the part of the water inlet channel 103 in contact with the humid and hot air in the air chamber 101 can be increased, so that the heat of the humid and hot air in the air chamber 101 can be better transferred to the water in the water inlet channel 103, thereby improving the heat recovery efficiency of the humid and hot air.

[0055] Optionally, the percentage of the volume of the water inlet channel 103 in the volume of the housing 10 is greater than or equal to 3%; in this way, the volume of the water inlet channel 103 is relatively large, and it can better absorb the heat inside and around the respirator 1 (mainly the body 2 of the dishwasher). Further optionally, the percentage of the volume of the water inlet channel 103 in the volume of the housing 10 is greater than or equal to 5%.

[0056] In this embodiment, optionally, the water inlet channel 103 includes a water inlet section 1031 and a water outlet section 1032, the upper end of the water inlet section 1031 is connected to the upper end of the water outlet section 1032, the second water inlet 103a is arranged at the lower end of the water inlet section 1031, and the second water outlet 103b is arranged at the lower end of the water outlet section 1032. Without loss of generality, in this embodiment, the air cavity 101 is located on the side of the water inlet section 1031 away from the water storage cavity 102, and the water storage cavity 102 is located on the side of the water outlet section 1032 away from the air cavity 101, and 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, and the anti-siphon structure is provided with a water inlet vent 103c connected to the upper part of the water storage cavity 102, and the water inlet vent 103c can be connected to the air cavity 101 via the connection between the water storage cavity 102 and the air cavity 101, and then connected to the outside atmosphere. When the water supply to the water inlet channel 103 is stopped, negative pressure is formed upstream of the water inlet channel 103, so that the water retained in the downstream of the water inlet channel 103 has a tendency to flow back due to siphoning. Since the water inlet vent 103c is connected to the atmosphere, the air in the atmosphere can enter the water inlet channel 103 through the water inlet vent 103c to balance the pressure difference in the water inlet channel 103 and prevent the water inlet channel 103 from siphoning. Optionally, the anti-siphon structure includes a bent channel section 1033 and a rotating channel section 1034, the bent channel section 1033 protrudes upward, one end of the bent channel section 1033 is connected to the upper end of the water inlet section 1031, the rotating channel section 1034 is arranged side by side below the bent channel section 1033, one end of the rotating channel section 1034 is connected to the other end of the bent channel section 1033, and the other end of the rotating channel section 1034 is connected to the water outlet section 1032, and the rotating channel section 1034 is provided with the water inlet vent 103c, and the water inlet vent 103c is usually arranged in a slit. It should be noted that, in the present embodiment, the water retaining rib 1021 is connected to the water inlet section 1031 at a position located below the turning channel section 1034; the first water passage 102d arranged in a tunnel manner will not pass through the water outlet section 1032 and the water inlet section 1031, thereby preventing the first water passage 102d from affecting the smoothness of the water flow in the water outlet section 1032 and the water inlet section 1031.

[0057] Further, a reclaimed water chamber 105 is defined between the water inlet section 1031 and the water outlet section 1032. The reclaimed water chamber 105 is provided with a third water outlet 105a for connecting to a water softener. It should be noted that the third water outlet 105a is connected to the water inlet end of the salt chamber of the water softener. Without loss of generality, the salt chamber of the water softener is provided with regenerated salt or a high-concentration salt solution. During the operation of the water softener, reclaimed water needs to be periodically introduced into the salt chamber. The reclaimed water introduced into the salt chamber forms a regenerated salt solution. When the softening performance of the soft water resin in the resin chamber decreases and the soft water resin needs to be restored, the regenerated salt solution formed in the salt chamber enters the resin chamber to restore and regenerate the soft water resin. In this embodiment, the spaced arrangement of the water inlet section 1031 and the water outlet section 1032 serves to form the reclaimed water chamber 105, making the structure of the respirator 1 simpler. Additionally, the spaced arrangement of the water inlet section 1031 and the water outlet section 1032 also enables the water inlet section 1031 and the water outlet section 1032 to absorb heat from different positions, thereby improving the heat absorption efficiency. At the same time, it is also beneficial to extend the overall length of the water inlet passage 103, thus increasing the heat absorption capacity of the water inlet passage 103.

[0058] Further, a second water passage 105b is also defined in the housing 10 to communicate the water storage chamber 102 with the upper end of the reclaimed water chamber 105. In this embodiment, during the process of filling the water storage chamber 102 with water, water can be injected into the reclaimed water chamber 105 through the second water passage 105b, so as to inject reclaimed water into the salt chamber of the water softener through the third water outlet 105a when the soft water resin in the resin chamber needs to be restored and regenerated. Additionally, the reclaimed water in the reclaimed water chamber 105 can also absorb the heat dissipated by the body 2 of the dishwasher during operation, thereby recovering this part of the heat and reducing the power consumption of the dishwasher. In this embodiment, optionally, the second water passage 105b is configured in the form of a tunnel, that is, the second water passage 105b does not pass through the water outlet section 1032, but is formed in the housing body of the housing 10 in the form of a tunnel and bypasses the water outlet section 1032 to avoid the second water passage 105b affecting the smooth water outlet of the water outlet section 1032.

[0059] Furthermore, an air passage 105c is defined within the housing 10 to connect the spaced - apart space between the water inlet section 1031 and the water outlet section 1032 with the water storage chamber 102. The air passage 105c is located above the second water passage 105b. Thus, during the water injection process of the water storage chamber 102, when the water submerges the second water passage 105b and fills the regenerated water chamber 105, as the water continues to rise, due to the existence of the air passage 105c, the water in the spaced - apart space above the regenerated water chamber 105 can rise simultaneously with the water in the water storage chamber 102. Optionally, the air passage 105c is configured in the form of a tunnel. That is, the air passage 105c does not pass through the water outlet section 1032, but is formed in the housing body of the housing 10 in the form of a tunnel and bypasses the water outlet section 1032 to prevent the air passage 105c from affecting the smooth water discharge of the water outlet section 1032. Additionally, optionally, above the second water passage 105b, the water inlet section 1031 and the water outlet section 1032 are close to each other and extend in parallel, and this part of the water outlet section 1032 is offset towards the water inlet section 1031 to make more space for the water storage chamber 102, so as to facilitate pre - storing more water.

[0060] Optionally, the percentage of the volume of the regenerated water chamber 105 in the volume within the housing 10 is greater than or equal to 3%. Thus, the regenerated water chamber 105 has a relatively large volume and can better absorb the heat inside and around the respirator 1 (mainly the body 2 of the dishwasher). Further optionally, the percentage of the volume of the regenerated water chamber 105 in the volume within the housing 10 is greater than or equal to 5%.

[0061] In the present invention, furthermore, a condensation chamber 101c is provided in the air chamber 101 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 to reduce the leakage of the humid and hot air through the condensation chamber 101c. At the same time, multiple chamber walls of the condensation chamber 101c can provide condensation effects, with a relatively high condensation efficiency, and can well recover the heat energy in the humid and hot air. Moreover, the condensed water condensed by the condensation chamber 101c can flow back to the communication port 101b through its opening and then flow back to the washing chamber 20 through the communication port 101b to achieve the recovery of the condensed water, thereby enabling the dishwasher to keep warm and save energy and reducing the energy consumption of the dishwasher.

[0062] Further, the breathing port 101a is located below the communication port 101b; in this way, on the one hand, due to the light weight characteristics 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 condense 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 there will be no dirt and static foreign objects entering the washing chamber 20.

[0063] Further, the air chamber 101 is further provided with a breathing passage 101e communicating the breathing port 101a and the communication port 101b; the breathing passage 101e includes a first passage segment e1 adjacent to the communication port 101b, and the first passage segment e1 extends in the up and down direction; in this way, a small amount of humid and hot air moving towards 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 passage wall of the first passage segment e1, so as to further improve the heat preservation and energy-saving ability of the dishwasher, thereby reducing the energy consumption of the dishwasher.

[0064] In this embodiment, optionally, the first passage segment e1 extends obliquely upward; in this way, the passage length of the first passage segment e1 of the same height can be extended, thereby increasing the condensation stroke of the first passage segment e1 and improving the condensation ability of the first passage segment e1 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 breathing passage 101e. Further optionally, the first passage segment e1 is arranged in a concave arc shape. On the one hand, it can further extend the passage length of the first passage segment e1, and on the other hand, it is conducive to the condensed water condensed on the passage wall of the first passage segment 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.

[0065] Optionally, the breathing passage 101e further includes a second passage segment e2 extending from top to bottom, and the middle position of the first passage segment e1 is communicated with the second passage segment e2. It can be understood that in most cases, the first passage segment e1 cannot recover all the water and heat in the humid and hot air entering the breathing passage 101e, that is, the air entering the second passage segment e2 still carries heat and water. In this embodiment, the humid and hot air leaking into the second passage segment e2 will gather at the upper end of the second passage segment e2 to condense condensed water at the upper end of the second passage segment e2, and part of these condensed waters can flow back to the communication port 101b from the first passage segment e1, thereby further recovering the condensed water and heat energy.

[0066] Further, the breathing channel 101e further includes a third channel segment e3 extending downward from top to bottom. The upper end of the third channel segment e3 communicates with the lower end of the second channel segment e2, and the breathing port 101a is provided at the lower end of the third channel segment e3. 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. Arranging the breathing port 101a at the lower end of the third channel segment e3 is conducive to making the breathing port 101a located below the communication port 101b. Optionally, the channel width of the third channel segment e3 is greater than that of the second channel segment 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.

[0067] Further, an insect-proof structure 101g is provided in the third channel segment e3 to limit insects such as cockroaches from entering the communication port 101b through the breathing channel 101e, thereby restricting insects such as cockroaches from entering the washing cavity 20 through the breathing port 101a.

[0068] 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 e3. It can be understood that the arrangement of the insect-proof ribs g1 can block insects such as cockroaches and prevent insects such as cockroaches 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 provided in the third channel segment e3.

[0069] 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 segment e3, and there is a gap between the other end and the channel side wall of the third channel segment e3 to form a breathing gap; and, in the extending direction of the third channel segment e3, any two adjacent insect-proof ribs g1 are arranged staggeredly. In this way, if insects such as cockroaches want to pass through the plurality of insect-proof ribs g1, they need to continuously change their crawling directions, which can effectively increase the difficulty for insects such as cockroaches to pass through.

[0070] Further, among any three adjacent insect-proof ribs g1, the 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.

[0071] Furthermore, 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. 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 breathing channel 101e is generally flat and has four side walls. The four side walls enclose the channel side walls, 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.

[0072] Furthermore, 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 standing firm, so as to further increase the difficulty for insects such as cockroaches to pass through.

[0073] Furthermore, the width w2 of at least one of the breathing gaps is smaller than the width w1 of the breathing port 101a (see Figure 4 ). In this way, even if some insects pass through the breathing port 101a, they cannot pass through the smaller breathing gap and thus cannot enter the communication port 101b. Optionally, the widths of all the breathing gaps are 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. Furthermore, the width of the breathing gap gradually decreases in the direction away from the breathing port 101a. It can be understood that gradually decreasing 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 and affecting the breathing smoothness of the respirator 1.
