[0028] To solve problems such as fouling of the outdoor heat exchanger, the outdoor heat exchanger is usually cleaned manually at regular intervals. However, since the existing air conditioner outdoor unit is installed on the outdoor side, it is difficult to clean manually, the cleaning is rather troublesome, and the user experience is reduced. Alternatively, the heat exchanger is cleaned by a self-cleaning method. The self-cleaning is to strip dust through frosting and then take away the dust by the water during defrosting. However, since the air conditioner outdoor unit is directly exposed to the outdoor during operation, it is easier to generate calcium and magnesium compounds attached to the fin surface compared to the indoor unit, and the effect of removing them by the methods of frosting and defrosting is limited. For the cleaning of the outdoor heat exchanger, a water box can also be provided, and the dirt is sprayed and washed off by spraying a cleaning liquid through the water outlet on the water box; however, in this way, since the water injection structure on the water box is arranged at one end of the water box, the cleaning liquid near the water injection structure end is more than that at the end far from the water injection structure end, and thus there is a problem of uneven cleaning of the heat exchanger by the cleaning liquid, resulting in incomplete cleaning of the heat exchanger.

[0029] Therefore, an embodiment of the present application provides a cleaning liquid tank 100.

[0030] Refer to Figure 1 As shown, the cleaning liquid tank 100 is used in the air conditioner 1; the air conditioner 1 includes a heat exchanger 20, and the heat exchanger 20 exchanges heat with air through the heat exchange medium therein to achieve the purpose of heat exchange of the heat exchange medium. Refer to Figure 1 As shown, the cleaning liquid tank 100 is used to be arranged above the heat exchanger 20.

[0031] Refer to Figure 2 、 Figure 3 and Figure 4 As shown, an embodiment of the present application provides a cleaning liquid tank 100, and the cleaning liquid tank 100 includes:

[0032] A tank body 110, the tank body 110 includes a bottom tank wall 111 and a side tank wall 112, and the bottom tank wall 111 and the side tank wall 112 enclose a liquid channel S1; and

[0033] A plurality of liquid discharge structures 120 are spaced apart on the bottom tank wall 111 for communicating the liquid channel S1 with the outside of the cleaning liquid tank 100; each of the liquid discharge structures 120 has an overflow section 121 extending into the liquid channel S1, the overflow section 121 has an overflow port 1211, the overflow port 1211 communicates with the liquid channel S1, and the overflow ports 1211 of the plurality of liquid discharge structures 120 are at the same horizontal position.

[0034] In the technical solution of the embodiment of the present application, the bottom tank wall 111 and the side tank wall 112 of the tank body 110 enclose to form a liquid channel S1; the liquid channel S1 is used to accommodate the cleaning liquid; the cleaning liquid tank 100 further includes a plurality of water discharge structures arranged on the bottom tank wall 111 for communicating the liquid channel S1 with the outside of the cleaning liquid tank 100, so that the cleaning liquid in the liquid channel S1 flows to the outside of the cleaning liquid tank 100 and flows to the heat exchanger 20 under the action of gravity to clean the heat exchanger 20; the liquid discharge structure 120 has an overflow section 121 extending into the liquid channel S1, the overflow section 121 has an overflow port 1211, and the cleaning liquid will flow into the overflow port 1211 only when it is flush with the overflow port 1211, and then flow out of the cleaning liquid tank 100; the overflow ports 1211 of each liquid discharge structure 120 are at the same horizontal position, so no matter where the plurality of water discharge structures are arranged, the cleaning liquid in the liquid channel S1 needs to accumulate to a certain height before flowing into different overflow ports 1211 at the same time, and the heat exchanger 20 can be cleaned comprehensively and evenly, thus solving the technical problem of uneven distribution of the cleaning liquid.

[0035] It should be noted that the cleaning liquid tank 100 further includes a liquid inlet structure 130 arranged on the tank body 110. In the technical solution of the embodiment of the present application, whether it is the liquid discharge structure 120 far from the liquid inlet structure 130 or the liquid discharge structure 120 close to the liquid inlet structure 130, the cleaning liquid needs to accumulate to the same horizontal position where the plurality of overflow ports 1211 are located before flowing into the overflow ports 1211.

[0036] In the embodiment,

[0037] In the technical solution of the embodiment of the present application, the cleaning liquid is used to clean the heat exchanger 20, and the cleaning liquid can be a cleaning medium in the prior art, such as a weakly acidic liquid; in some embodiments, the cleaning liquid can be formed according to a certain mass ratio of water and scale remover.

[0038] As an alternative implementation of the above embodiment, such as Figure 3As shown, the tank body 110 has an extending direction, and a plurality of the liquid inlet structures 120 are arranged at intervals along the extending direction; and / or the tank body 110 has a width direction, and a plurality of the liquid inlet structures 120 are arranged at intervals along the width direction. For those skilled in the art, it is easy to think that the shape and size of the tank body 110 are adapted to those of the heat exchanger 20. In the technical solution of this embodiment, the extending direction and the width direction of the tank body 110 are determined according to the shape of the heat exchanger 20. For example, as Figure 2 shown, the heat exchanger 20 is generally L-shaped, so the extending direction of the tank body 110 extends in an L-shape; the width direction of the tank body 110 is perpendicular to the extending direction; the width and the extending length of the tank body 110 are adapted to the size of the heat exchanger 20.

[0039] In some embodiments, when the heat exchanger is in a straight shape, the tank body extends straight.

[0040] In this embodiment, the liquid inlet structures 120 are arranged at intervals along the extending direction, so as to facilitate the heat exchanger 20 to inject the cleaning liquid at various positions in its extending direction; the liquid inlet structures 120 are arranged at intervals along the width direction, so as to facilitate the heat exchanger 20 to inject the cleaning liquid at various positions in its width direction. In some embodiments, the liquid inlet structures 120 are arranged at intervals both along the extending direction and along the width direction, so as to facilitate injecting the cleaning liquid into all positions of the heat exchanger 20 sufficiently.

[0041] In the embodiment, the arrangement density and the arrangement mode of the liquid inlet structures 120 are specifically set according to the size of the heat exchanger 20, and the present application does not make specific limitations. For example, the liquid inlet structures 120 are arranged at intervals in a straight line or cross-arranged along the extending direction.

[0042] As an alternative implementation of the above embodiment, the liquid inlet structure 120 has a liquid outlet (not shown) and a liquid outlet channel (not shown) located outside the bottom tank wall 111, and the liquid outlet channel communicates with the liquid outlet and the overflow port 1211; wherein, the liquid outlet is connected to a spray head (not shown); and / or the cleaning liquid tank 100 further includes a sponge structure (not shown), and the sponge structure covers the liquid outlet. In the embodiment, when the cleaning liquid accumulates to the horizontal position where the overflow port 1211 is located, it flows into the liquid outlet channel through the overflow port 1211, and then flows out of the cleaning liquid tank 100 through the liquid outlet. In this embodiment, a spray head is connected to the liquid outlet, and the spray head sprays the cleaning liquid to spray towards the heat exchanger 20, so as to achieve the purpose of cleaning the heat exchanger 20 and further improve the uniformity of the cleaning liquid sprayed towards the heat exchanger 20; or in the embodiment, a sponge structure is provided at the liquid outlet, and the sponge structure covers the liquid outlet interface, further improving the uniformity of the cleaning liquid injected into the heat exchanger 20.

[0043] In an embodiment, the sponge structure can be attached to the bottom of the bottom groove wall 111 by means of pasting, clamping, etc. The spray head can be connected to the liquid outlet by means of screw connection, flange connection.

[0044] As an alternative implementation of the above embodiment, as Figure 2 , Figure 3 and Figure 4 shown, the liquid channel S1 has a first end B1 and a second end B2, and the bottom groove wall 111 is inclined with respect to the horizontal plane S2 so that a drop is formed between the first end B1 and the second end B2, and the first end B1 is higher than the second end B2; the cleaning liquid tank 100 further includes a liquid discharge structure for connecting to the liquid storage box 300; the liquid discharge structure is provided on the tank body 110 and is disposed near the second end B2. After the heat exchanger 20 is cleaned, the cleaning liquid in the liquid channel S1 flows into the liquid storage box 300 through the liquid discharge interface under the action of gravity, ensuring that the cleaning liquid in the liquid channel S1 can flow back to the liquid storage box 300 after the heat exchanger 20 is cleaned, and avoiding the accumulation of the cleaning liquid in the liquid channel S1.

[0045] In this embodiment, even if the bottom groove wall 111 is inclined, since the plurality of overflow ports 1211 are at the same horizontal position, it is also necessary for the cleaning liquid to accumulate to this same horizontal position before flowing into the overflow ports 1211. Therefore, while ensuring that the cleaning liquid in the liquid channel S1 can flow back to the liquid storage box 300 after the heat exchanger 20 is cleaned, the uniformity of the cleaning liquid poured into the heat exchanger 20 can also be ensured.

[0046] In an embodiment, the liquid discharge structure is communicated with the liquid storage box 300 through a drain pipe; a valve is provided on the drain pipe. When the valve is opened, the cleaning liquid in the liquid channel S1 flows back to the liquid storage box 300. For example, the valve can be an electromagnetic valve.

[0047] As an alternative implementation of the above embodiment, the tank body 110 has an extending direction; the bottom groove wall 111 has a liquid channel surface S10 of the liquid channel S1; the liquid channel surface S10 extends along the extending direction and gradually deviates from the heat exchanger 20 to be inclined with respect to the horizontal plane S2. The liquid channel surface S10 is the wall surface on the side of the bottom groove wall 111 facing away from the heat exchanger 20. The liquid channel surface S10 extends along the extending direction. When the cleaning tank body 110 is installed above the heat exchanger 20, and gradually deviates from the heat exchanger 20, and then is inclined relative to the horizontal plane S2, so that the cleaning liquid in the liquid channel S1 flows into the liquid storage box 300 through the liquid discharge interface under the action of gravity.

[0048] As an alternative implementation of the above embodiment, as Figure 2 shown, the distances between the plurality of overflow ports 1211 and the liquid channel surface S10 gradually increase in the extending direction from the first end B1 to the second end B2. Refer toFigure 3 As shown, the distance between the overflow port 1211 and the liquid channel surface S10 is H; in the extending direction, from the first end B1 (high end) to the second end B2 (low end), H gradually increases. The distance between the overflow port 1211 at the position closest to the first end B1 and the liquid channel surface S10 is the smallest, and the height of the cleaning liquid to be accumulated at this position is the smallest; the distance between the overflow port 1211 at the position closest to the second end B2 and the liquid channel surface S10 is the largest, and the height of the cleaning liquid to be accumulated at this position is the largest; when the cleaning liquid is put into the liquid channel S1, affected by gravity, the cleaning liquid will flow in from the overflow port 1211 only when it accumulates to the horizontal position where the overflow port 1211 is located. The overflow port 1211 at the position closest to the first end B1 satisfies the overflow of the cleaning liquid at a relatively small accumulation height, and the overflow port 1211 at the position closest to the second end B2 needs a relatively large accumulation height to satisfy the overflow of the cleaning liquid, thereby evenly putting the cleaning liquid into the heat exchanger 20.

[0049] As an alternative embodiment of the above embodiment, the included angle between the liquid channel surface S10 and the horizontal plane S2 ranges from 2° to 5°. In the embodiment, this included angle can be 2°, 2.5°, 3°, 3.5°, 4°, 4.5° or 5°.

[0050] As an alternative embodiment of the above embodiment, the cleaning liquid tank 100 further includes a liquid inlet structure 130, and the liquid inlet structure 130 is arranged close to the second end B2. In some embodiments, when the cleaning liquid tank 100 is installed inside the air conditioner 1, the cleaning liquid needs to be put into the cleaning liquid tank 100 through the liquid inlet structure 130; the putting of the cleaning liquid needs to pump the cleaning liquid in the liquid storage box 300 into the cleaning tank through the water inlet pipe 400 by the water pump 200; the liquid inlet structure 130 is arranged close to the second end B2, that is, the liquid inlet structure 130 and the liquid discharge structure are arranged at positions close to each other, which can arrange the water pump 200 and the liquid storage box 300 on the same side to reduce the layout range of the water inlet pipe 400 and is beneficial to the optimization of the internal space of the air conditioner 1.

[0051] In the technical solution of the embodiment of the present application, both the liquid inlet structure 130 and the liquid outlet structure can be a water pipe joint or a joint for connecting pipelines.

[0052] Combined Figure 1 As shown, the present application provides a cleaning assembly 10, including: a liquid supply structure and a cleaning liquid tank 100; the liquid supply structure is configured to supply cleaning liquid to the liquid channel S1. The cleaning liquid tank 100 adopts a part or all of the technical solutions of the foregoing embodiments, so the cleaning liquid tank 100 has part or all of the technical advantages of the foregoing embodiments.

[0053] In some embodiments, such as Figure 1As shown in the figure, the liquid supply structure includes a water pump 200, a liquid storage box 300, and a water inlet pipe 400. The water inlet pipe 400 connects the water pump 200 and the cleaning liquid tank 100. The water pump 200 pumps the cleaning liquid in the liquid storage box 300 through the water inlet pipe 400 and sends it into the cleaning liquid tank 100. When the heat exchanger 20 needs to be cleaned, the water pump 200 starts, pumps the cleaning liquid in the liquid storage box 300, and sends it into the cleaning liquid tank 100 through the water inlet pipe 400; when the cleaning liquid accumulates to the horizontal position where the overflow port 1211 is located, it enters the overflow port 1211 and is poured onto the heat exchanger 20.

[0054] When cleaning the heat exchanger 20, the water level of the cleaning liquid in the cleaning liquid tank 100 can be detected; when the water level is lower than the horizontal position of the overflow port 1211 (low water level), the water pump 200 runs continuously to quickly accumulate the cleaning liquid to the horizontal position of the overflow port 1211.

[0055] When the water level is higher than the horizontal position of the overflow port 1211 (low water level), the water pump 200 can run intermittently to quickly accumulate the cleaning liquid to the horizontal position of the overflow port 1211. Due to the flow characteristics of the cleaning liquid, continuous water flow tends to flow along a single path, resulting in a single water path and uneven water drainage. By controlling the intermittent operation of the water pump 200 (such as running for 5 s and stopping for 3 s, running for 3 s and stopping for 2 s, etc.), each water path is different, improving the uniformity of water drainage.

[0056] When the self-cleaning program is running and the water level is higher than the horizontal position of the overflow port 1211 (low water level), the water pump 200 starts intermittent operation, and the cleaning liquid in the liquid storage box 300 flows into the cleaning liquid tank 100 and flows down from top to bottom along the heat exchanger 20 through the cleaning liquid tank 100, reacting with calcium and magnesium compounds on the fins and copper tubes of the heat exchanger 20 and slowly dissolving them. Synchronously, the air-conditioning system turns on the cooling mode (the heat exchanger 20 acts as a condenser), raising the temperature of the outdoor heat exchanger 20, which is beneficial to accelerating the reaction speed and effect of the cleaning liquid with scale such as calcium and magnesium compounds.

[0057] In a third aspect, the present application also proposes an air conditioner 1, including: a heat exchanger 20 and a cleaning liquid tank 100. The cleaning liquid tank 100 is arranged above the heat exchanger 20 and is used to supply cleaning liquid to the heat exchanger 20. The cleaning liquid tank 100 adopts part or all of the technical solutions of the foregoing embodiments, so the cleaning liquid tank 100 has part or all of the technical advantages of the foregoing embodiments.

[0058] Alternatively, the air conditioner 1 includes a heat exchanger 20 and a cleaning assembly 10. The cleaning liquid tank 100 of the cleaning assembly 10 is disposed above the heat exchanger 20 and is used to supply cleaning liquid to the heat exchanger 20. The cleaning assembly 10 adopts a part or all of the technical solutions of the foregoing embodiments, and thus the cleaning assembly 10 has a part or all of the technical advantages of the foregoing embodiments.

[0059] The foregoing are only alternative embodiments of the present application, and thus do not limit the patent scope of the present application. Any equivalent structural transformation made under the application concept of the present application by using the content of the specification and drawings of the present application, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
