Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples.

In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.

[0045] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0046] The air conditioner 100 according to an embodiment of the present invention, as Figure 1 shown, includes an indoor unit component 110 adapted to be provided on the indoor side. The indoor unit component 110 includes: a heat exchange component 1, a chassis 2, and a filter member 4. The heat exchange component 1 includes an indoor heat exchanger 11 and an indoor water receiving tray 12 provided below the indoor heat exchanger 11. As Figure 1 and Figure 2 shown, the chassis 2 includes a water storage part 21 and a partition 22. The partition 22 is at least one and is provided in the water storage part 21 to divide a plurality of water tanks 3 in the water storage part 21. The plurality of water tanks 3 include a primary water tank 31 capable of receiving the drainage of the indoor water receiving tray 12. The partition 22 is separated between two adjacent water tanks 3, and the partition 22 has a communication port 22a communicating with the two water tanks 3 on both sides thereof. The filter member 4 is detachably mounted on the partition 22 and blocks the communication port 22a.

[0047] The indoor heat exchanger 11 is used to exchange heat with indoor air to adjust the indoor temperature. During the heat exchange process of the indoor heat exchanger 11, the moisture in the air is cooled and liquefied, forming condensed water that adheres to the indoor heat exchanger 11 and flows down in a stream under the action of gravity. An indoor water receiving tray 12 is provided below the indoor heat exchanger 11 to collect the condensed water generated on the indoor heat exchanger 11 for subsequent treatment of the condensed water.

[0048] As Figure 1 shown, the chassis 2 is arranged below the indoor water receiving tray 12, and the water receiving part 21 of the chassis 2 is used to receive the condensed water collected on the indoor water receiving tray 12. Exemplarily, the condensed water in the indoor water receiving tray 12 can directly flow into the water receiving part 21 under the action of gravity, or can be transmitted to the water receiving part 21 through a water guiding member.

[0049] At least one partition 22 is arranged in the water receiving part 21 to divide the internal space of the water receiving part 21 into multiple water tanks 3. The partition 22 and the water receiving part 21 jointly define multiple water tanks 3, and there must be a partition 22 between two adjacent water tanks 3 for separation. A communication port 22a is opened on the partition 22, and the condensed water can flow through the communication port 22a through multiple water tanks 3 in sequence. By arranging the partition 22 to divide the water receiving part 21 into multiple water tanks 3, the structure can be simplified and the manufacturing difficulty can be reduced.

[0050] Among the multiple water tanks 3, there is a primary water tank 31. The primary water tank 31 can receive the drainage of the indoor water receiving tray 12. When the condensed water is transmitted from the indoor water receiving tray 12 to the water receiving part 21, it first flows into the primary water tank 31. Subsequently, the condensed water flows through the communication port 22a on the partition 22 forming the primary water tank 31 into the water tank 3 adjacent to the primary water tank 31, and then passes through multiple water tanks 3 in sequence.

[0051] A filter element 4 is arranged at the communication port 22a of each partition 22. The condensed water flows through multiple water tanks 3 in sequence to complete multiple filtrations, thereby improving the cleanliness of the condensed water in the most downstream water tank 3 in the water receiving part 21. After being filtered, the condensed water can be subjected to the next treatment, such as being used for indoor humidification, indoor enhanced heat exchange, cleaning of the indoor heat exchanger 11, outdoor enhanced heat exchange, cleaning of the outdoor heat exchanger 73, etc. The filtered condensed water has better cleanliness and will not pollute the indoor environment or the outdoor environment.

[0052] After being used for a period of time, impurities will adhere to the filter element 4, and the filter element 4 needs to be cleaned or replaced to continue filtering the condensed water.

[0053] The filter element 4 of the embodiment of the present utility model is detachably installed on the partition 22. The filter element 4 is only connected to the partition 22. The disassembly and assembly operation of the filter element 4 is simple, and it is more convenient to clean or replace the filter element 4, which can improve the use convenience of the air conditioner 100.

[0054] According to the air conditioner 100 of the embodiment of the present utility model, by providing a detachable filter element 4 on the partition plate 22, the filter element 4 is only connected to the partition plate 22, and the disassembly and assembly operations of the filter element 4 are simple, which is more convenient for cleaning or replacing the filter element 4, and can improve the use convenience of the air conditioner 100.

[0055] In some embodiments of the present utility model, such as Figure 3 and Figure 5 shown, the partition plate 22 is provided with a slot 22b. The slot 22b is located at the edge of the communication port 22a and penetrates upward in the vertical direction. The two ends of the filter element 4 can be inserted into the slot 22b in an upwardly extractable manner.

[0056] The two ends of the filter element 4 are inserted into the slot 22b in the vertical direction. During the process of installing the filter element 4 onto the partition plate 22, the slot 22b plays a guiding role, enabling the filter element 4 to move stably in the vertical direction, avoiding installation displacement, and improving the assembly efficiency and assembly yield.

[0057] When the filter element 4 is installed on the partition plate 22, the slot wall of the slot 22b covers the outer edge of the filter plate, playing a limiting role on the filter element 4, reducing the occurrence of the situation where the condensate water impacts the filter element 4 and causes the filter element 4 to shift or detach, and improving the working stability of the filter element 4.

[0058] During the process of disassembling the filter element 4 from the partition plate 22, the slot 22b plays a guiding role, which can improve the disassembly efficiency of the filter element 4.

[0059] In some embodiments of the present utility model, the slot 22b includes a bottom wall extending along the thickness direction of the partition plate 22 and side walls connected to both sides of the bottom wall. The filter element 4 is inserted into the slot 22b, and the slot wall of the slot 22b can limit the movement of the filter element 4 along the thickness direction of the partition plate 22.

[0060] In some embodiments of the present utility model, such as Figure 3 shown, a stop portion 23 is provided at the bottom of the communication port 22a. The stop portion 23 stops at the upstream side and / or downstream side of the lower end of the filter element 4.

[0061] By providing a stop portion 23 at the bottom of the communication port 22a to stop the lower end of the filter element 4, the situation where the condensate water impacts the filter element 4 and causes the filter element 4 to shift or detach can be improved, the installation stability of the filter element 4 can be improved, and the working reliability of the filter element 4 can be improved.

[0062] Optionally, the stop portion 23 may be provided on the upstream side of the filter element 4; alternatively, further optionally, the stop portion 23 may be provided on the downstream side of the filter element 4; or, further optionally, stop portions 23 are provided on both the upstream side and the downstream side of the filter element 4 to limit the filter element 4. Herein, the upstream side and the downstream side are based on the flow direction of the condensed water. The condensed water flows through the filter element 4, the inflow direction side of the condensed water is the upstream side, and the outflow direction of the condensed water is the downstream side.

[0063] In some embodiments of the present invention, as Figure 5 shown, one surface of the stop portion 23 facing the filter element 4 is formed as a guide surface 231 that extends obliquely away from the filter element 4 in a direction from bottom to top.

[0064] One surface of the stop portion 23 facing the filter element 4 is inclined gradually toward the filter element 4 in the direction from top to bottom, that is, the gap between the stop portion 23 and the filter element 4 gradually decreases in the direction from top to bottom. On the one hand, the stop portion 23 can improve the limiting effect on the filter element 4 and enhance the installation stability of the filter element 4. On the other hand, the stop portion 23 can also play a guiding role for the filter element 4, can improve the assembly and disassembly efficiency of the filter element 4, and reduce the operation difficulty.

[0065] In some embodiments of the present invention, as Figure 5 shown, a clamping groove 23a that is recessed in a direction away from the transition member is formed at the bottom of one side of the stop portion 23 facing the filter element 4. A clamping protrusion 4a is provided at the bottom of the filter element 4. When the filter element 4 is installed into the communication port 22a, the clamping protrusion 4a is in clamping fit with the clamping groove 23a, further enhancing the installation stability of the filter element 4.

[0066] In some embodiments of the present invention, as Figure 3 and Figure 5 shown, the stop portion 23 stops at the upstream side of the lower end of the filter element 4. Clamping protrusions 4a are provided at both bottoms on the two thickness sides of the filter element 4. The filter element 4 is an axisymmetric structural member. By setting the filter element 4 as a symmetric structure, the filter element 4 can be stably installed at the communication port 22a whether it is installed correctly or reversely, and the installation operation of the filter element 4 is simple.

[0067] In some embodiments of the present invention, as Figure 3 and Figure 5 shown, clamping protrusions 4a are provided at both the top and the bottom on the two thickness sides of the filter element 4. The filter element 4 is an axisymmetric structural member. The filter element 4 can be stably installed at the communication port 22a whether it is installed correctly, reversely, or upside down, further reducing the installation difficulty.

[0068] In some embodiments of the present invention, as Figure 3As shown, the stop portion 23 stops on the upstream side of the lower end of the filter element 4, and a stop plate 22c is provided on the partition plate 22. The stop plate 22c stops on the downstream side of the lower end of the filter element 4. The stop plate 22c and the stop portion 23 respectively stop on the upstream side and the downstream side of the lower end of the filter element 4, which can improve the stability of the filter element 4.

[0069] As Figure 3 shown, there are two stop plates 22c at the communication port 22a, and they are respectively connected to the two slots 22b, and the two stop plates 22c extend towards each other.

[0070] In some embodiments of the present utility model, as Figure 4 shown, there are multiple partition plates 22 including a first partition plate 221 and a second partition plate 222. The multiple water tanks 3 include a primary water tank 31, an intermediate water tank 32, and a final water tank 33 arranged in sequence along the water passing direction. The first partition plate 221 is separated between the primary water tank 31 and the intermediate water tank 32, and the second partition plate 222 is separated between the intermediate water tank 32 and the final water tank 33. There are multiple filter elements 4 including a first filter element 41 and a second filter element 42. The first filter element 41 is detachably installed on the first partition plate 221, and the second filter element 42 is detachably installed on the second partition plate 222.

[0071] The condensed water discharged from the indoor water receiving tray 12 first enters the primary water tank 31, and then the condensed water enters the intermediate water tank 32 after being filtered by the first filter element 41 on the first partition plate 221, and the condensed water is filtered once. Then the condensed water enters the final water tank 33 after being filtered by the second filter element 42 on the second partition plate 222, and the condensed water is filtered twice.

[0072] Thus, the condensed water entering the final water tank 33 is relatively clean after being filtered twice, and can be processed in the next step.

[0073] In some embodiments of the present utility model, as Figure 3 and Figure 4 shown, the indoor unit component 110 further includes: a detection device 51, and the detection device 51 is arranged at the intermediate water tank 32 and is used to detect the water level of the intermediate water tank 32. By setting the detection device 51, the water level of the intermediate water tank 32 can be detected, and the situation that the condensed water accumulates too much and overflows in the water receiving portion 21 can be reduced. When the detection device 51 detects that the water level in the intermediate water tank 32 is relatively high, since the primary water tank 31, the intermediate water tank 32, and the final water tank 33 are interconnected, it can be judged that there is more condensed water in the water receiving portion 21, that is, it is prompted that the condensed water needs to be discharged. Or it may be that the second filter element 42 is blocked, resulting in poor flow of the condensed water, and it can be prompted to clean or replace the second filter element 42.

[0074] As Figure 4As shown in the figure, the primary water tank 31 is arranged on one side in the width direction of the intermediate water tank 32, and the final water tank 33 is arranged at one end in the length direction of the intermediate water tank 32. The detection device 51 and the first filter element 41 are arranged in sequence along the direction from the intermediate water tank 32 to the final water tank 33 to avoid the first filter element 41 and the second filter element 42.

[0075] The detection device 51 is arranged farther from the final water tank 33 than the first filter element 41. Therefore, the arrangement position of the detection device 51 will not interfere with the flow of condensed water through the first filter element 41, nor will it interfere with the flow of condensed water through the second filter element 42, improving the smoothness of the flow of condensed water in the water receiving part 21. And when disassembling and assembling the first filter element 41 and the second filter element 42, the arrangement position of the detection device 51 can also reduce the interference with the operation and reduce the difficulty of disassembly and assembly.

[0076] In some embodiments of the present utility model, as Figure 3 shown, the detection device 51 includes a first detection device 511 and a second detection device 512. The installation heights of the first detection device 511 and the second detection device 512 are different. The first detection device 511 detects whether the water level in the intermediate water tank 32 reaches a first preset height, and the second detection device 512 detects whether the water level in the intermediate water tank 32 reaches a second preset height. The first preset height is higher than the second preset height. The different first preset height and second preset height are for more accurately obtaining the water level condition in the intermediate water tank 32, being able to timely handle the condensed water in the water receiving part 21, and solving the energy consumption problem.

[0077] The first detection device 511 and the second detection device 512 are arranged at intervals along the length direction of the intermediate water tank 32 to avoid the first filter element 41 and the second filter element 42, and facilitate the arrangement of the first detection device 511 and the second detection device 512.

[0078] In some embodiments of the present utility model, the indoor unit component 110 further includes: an indoor unit housing. The heat exchange component 1 and the chassis 2 are both arranged inside the indoor unit housing. There is a maintenance opening on the indoor unit housing, and the maintenance opening is located on the side of the intermediate water tank 32 away from the primary water tank 31 in the width direction.

[0079] The indoor unit housing plays a protective role for the internal heat exchange component 1 and the chassis 2. By opening a maintenance opening on the indoor unit housing, when cleaning and replacing the filter element 4, it is not necessary to disassemble the entire indoor unit housing. Only by opening the maintenance opening can the operation be completed. The operations of maintaining and replacing the filter element 4 are simple and convenient to use.

[0080] The primary water tank 31 is located on one side in the width direction of the intermediate water tank 32. The primary water tank 31 is used to receive the condensed water from the indoor water receiving tray 12. The heat exchange component 1 is also arranged on one side in the width direction of the intermediate water tank 32. Therefore, a maintenance opening is provided on the inner machine housing on the other side in the width direction of the intermediate water tank 32 for operation, which can avoid the interference generated by the heat exchange component 1 during the operation process. And the arrangement of the detection device 51 also avoids the maintenance opening, which can further reduce the interference with the disassembly and assembly operation of the filter element 4.

[0081] Since the intermediate water tank 32 is adjacent to both the primary water tank 31 and the final water tank 33, a maintenance opening is provided on the inner machine housing at the width side part of the intermediate water tank 32. Through the maintenance opening, both the first filter element 41 and the second filter element 42 can be maintained and replaced.

[0082] In some embodiments of the present invention, such as Figure 3 and Figure 4 as shown, a drain port 24 is provided at the lower part of the water receiving part 21. The drain port 24 faces and communicates with the intermediate water tank 32, and a drain valve 25 for controlling the opening and closing of the drain port 24 is provided on the drain port 24.

[0083] The drain port 24 is used to drain the condensed water in the water receiving part 21. When the condensed water in the water receiving part 21 accumulates too much, or when the device for draining the condensed water in the final water tank 33 fails, the water in the water receiving part 21 can be drained through the drain port 24 to avoid damage and pollution to the air conditioner 100 caused by the overflow of the condensed water.

[0084] The drain valve 25 is used to control the opening and closing of the drain port 24. When the condensed water in the water receiving part 21 is less or the device for draining the condensed water in the final water tank 33 works normally, the drain valve 25 closes the drain port 24, and the water in the intermediate water tank 32 flows through the filter to the final water tank 33; when the drain valve 25 opens the drain port 24, the condensed water in the primary water tank 31 and the condensed water in the final water tank 33 both flow to the intermediate water tank 32 and flow out of the water receiving part 21 through the drain port 24.

[0085] In some embodiments of the present invention, the intermediate component includes a detection device 51 arranged at the intermediate water tank 32. A drain port 24 is provided at the lower part of the water receiving part 21. The drain port 24 faces and communicates with the intermediate water tank 32, and a drain valve 25 for controlling the opening and closing of the drain port 24 is provided on the drain port 24. The detection device 51 is signal-connected to the drain valve 25. When the detection device 51 detects that the water level in the intermediate water tank 32 is relatively high, it controls the drain valve 25 to open the drain port 24 to drain the condensed water in the water receiving part 21.

[0086] In some embodiments of the present utility model, the detection device 51 includes a first detection device 511 and a second detection device 512. The first detection device 511 detects whether the water level in the intermediate water tank 32 reaches a first preset height, and the second detection device 512 detects whether the water level in the intermediate water tank 32 reaches a second preset height. The first preset height is higher than the second preset height.

[0087] When the second detection device 512 detects that the water level in the intermediate water tank 32 reaches the second preset height, it indicates that there is a relatively large amount of condensed water in the water storage part 21, and the condensed water needs to be treated and discharged from the last-stage water tank 33. When the first detection device 511 detects that the water level in the intermediate water tank 32 reaches the first preset height, it indicates that there is too much condensed water in the water storage part 21. At this time, the drain port 24 needs to be opened to release the condensed water.

[0088] In some embodiments of the present utility model, as Figure 3 and Figure 4 shown, a plurality of water tanks 3 are arranged in sequence along the water passing direction, and the last stage is the last-stage water tank 33. The indoor unit component 110 further includes: a first pumping device 61, which is arranged at the last-stage water tank 33 and is used to pump the water in the last-stage water tank 33. A grounding plate 53 is provided at the bottom of the last-stage water tank 33.

[0089] The condensed water entering the last-stage water tank 33 is filtered through multiple stages. Therefore, the condensed water in the last-stage water tank 33 is relatively clean and can be pumped out by the first pumping device 61 and discharged from the water storage part 21.

[0090] The first pumping device 61 is an electrically charged component. The first pumping device 61 is arranged in the last-stage water tank 33 containing condensed water. Therefore, when the first pumping device 61 has a short circuit and leakage, there is still a risk of the condensed water conducting electricity. By providing the grounding plate 53 at the bottom of the last-stage water tank 33, when the first pumping device 61 leaks electricity, the current is conducted away to avoid the condensed water being charged and improve the use safety of the air conditioner 100.

[0091] In some embodiments of the present utility model, as Figure 3 and Figure 4 shown, the grounding plate 53 includes an extension part 531. The extension part 531 extends to the upper end of the last-stage water tank 33 and overlaps on the edge of the chassis 2. The extension part 531 is used for grounding connection with a metal part.

[0092] The grounding plate 53 includes an extension part 531 extending to the upper end of the last-stage water tank 33. The metal grounding part can be directly connected to the extension part 531, and the connection and arrangement of the metal grounding part are relatively simple.

[0093] In some embodiments of the present utility model, as Figure 1 and Figure 2As shown, the chassis 2 further includes a support portion 26. The water storage portion 21 is located at one end of the support portion 26 in the length direction, and the heat exchange assembly 1 is supported by the support portion 26. The support portion 26 and the water storage portion 21 are separated by a partition plate 2722 to prevent the condensed water in the water storage portion 21 from flowing to the support portion 26 and leaking out.

[0094] One end of the heat exchange assembly 1 close to the water storage portion 21 has a metal side plate, and the metal side plate is electrically connected to the grounding piece 53. By using the electrical connection between the metal side plate on the heat exchange assembly 1 and the grounding piece 53, and then grounding the metal side plate on the heat exchange assembly 1, the condensed water can be prevented from being charged, thus improving the safety of using the air conditioner 100. And by grounding the grounding piece 53 through the metal side plate on the heat exchange assembly 1, there is no need to additionally set up a metal grounding part, which can save manufacturing costs and reduce the layout difficulty.

[0095] In some embodiments of the present invention, as Figure 6 and Figure 10 shown, the air conditioner 100 is a window air conditioner 100a, and further includes an outdoor unit component 120 adapted to be arranged on the outdoor side. The outdoor unit component 120 includes an outdoor unit housing 71 and a spraying device 72. The outdoor unit housing 71 has an avoidance opening 71a, and the spraying device 72 is exposed through the avoidance opening 71a.

[0096] The filtered condensed water in the water tank 3 is conveyed to the spraying device 72. The spraying device 72 is exposed to the outdoor through the avoidance opening 71a, and the spraying assembly can directly face the outdoor and atomize and spray the condensed water, thereby consuming the condensed water in the water storage portion 21. And the condensed water has a relatively high cleanliness after being filtered by the filter element 4 in the water storage portion 21, which can reduce the occurrence of the situation that the impurities in the condensed water block the spraying device 72 and improve the working reliability of the spraying device 72.

[0097] As Figure 6 and Figure 7 shown, the air conditioner 100 further includes: a first pumping device 61, a first water pipeline 62 and a third filter element 4. The first pumping device 61 is arranged in the last-stage water tank 33 of the plurality of water tanks 3. One end of the first water pipeline 62 is connected to the first pumping device 61, and the other end extends to be connected to the spraying device 72 for conveying the water in the water tank 3 to the spraying device 72. The third filter element 4 is arranged in the first water pipeline 62.

[0098] The condensed water entering the last-stage water tank 33 is filtered through multiple stages. Therefore, the condensed water in the last-stage water tank 33 is relatively clean and can be extracted by the first pumping device 61 and conveyed to the spraying device 72. And by further providing a third filter element 4 in the first water pipeline 62 to filter the condensed water conveyed by the first pumping device 61 again, the cleanliness of the condensed water conveyed to the spraying device 72 can be further improved, the situation that the impurities in the condensed water block the spraying device 72 can be reduced, and the working reliability of the spraying device 72 can be improved.

[0099] In some embodiments of the present utility model, as Figure 8 shown, the air conditioner 100 further includes: a first protection pipe 81, and the first protection pipe 81 is sleeved outside the first water delivery pipeline 62. The texture of the first water delivery pipeline 62 is relatively soft. A first protective sleeve is sleeved outside the first water delivery pipeline 62 to enhance the structural strength, protect the internal first water delivery pipeline 62, and improve the working reliability of the first water delivery pipe.

[0100] As Figure 8 shown, the air conditioner 100 further includes: a first refrigerant pipe 82, and the first refrigerant pipe 82 and the first protection pipe 81 are bundled into a first heat transfer pipe group 80 through a first tightening member 84.

[0101] The spray device 72 is arranged in the outdoor unit part. Therefore, the first water delivery pipeline 62 extends from the indoor side to the outdoor side to supply water to the spray device 72. When the external temperature is relatively low in winter, the condensed water in the first water delivery pipeline 62 may freeze and block. Through the heat transfer cooperation between the first refrigerant pipe 82 and the first protection pipe 81, the heat of the first refrigerant pipe 82 is transferred to the first water delivery pipeline 62, which can prevent the first water delivery pipeline 62 from freezing and blocking when the ambient temperature is relatively low, and improve the working reliability of the first water delivery pipeline 62 for transferring condensed water.

[0102] Moreover, the structural strength of the first refrigerant pipe 82 is relatively high. The first tightening member 84 bundles the first refrigerant pipe 82 and the first protection pipe 81 into the first heat transfer pipe group 80, enhances the overall structural strength of the first heat transfer pipe group 80, protects the internal first water delivery pipeline 62, and improves the working reliability of the first water delivery pipe.

[0103] As Figure 6 and Figure 8 shown, the air conditioner 100 further includes: a first heat preservation pipe 83, and the first heat preservation pipe 83 is sleeved outside the first heat transfer pipe group 80. By arranging the first heat preservation pipe 83, the internal first water delivery pipeline 62 and the first refrigerant pipe 82 can be heat-preserved, and the influence of the ambient temperature on the first water delivery pipeline 62 and the first refrigerant pipe 82 can be reduced.

[0104] In some embodiments of the present utility model, a part of the refrigerant pipe of the air conditioner 100 is used as the first refrigerant pipe 82. By using the refrigerant pipe in the air conditioner 100 to exchange heat with the first water delivery pipeline 62, the manufacturing cost of additionally arranging a refrigerant pipe can be saved.

[0105] In some embodiments of the present utility model, the first tightening member 84 is a heat shrinkable tube, and the heat shrinkable tube is coated outside the first refrigerant pipe 82 and the first protective sleeve to form the first heat transfer pipe group 80.

[0106] In some embodiments of the present utility model, as Figure 6 、 Figure 7 andFigure 10 As shown in the figure, the air conditioner 100 is a window air conditioner 100a, and further includes an outdoor unit component 120 adapted to be disposed on the outdoor side. The outdoor unit component 120 includes an outdoor heat exchanger 73 and an outdoor water receiving tray 74 disposed below the outdoor heat exchanger 73.

[0107] It can be understood that the outdoor heat exchanger 73 exchanges heat with the outdoor air, and the moisture in the outdoor air will also adhere to the outdoor heat exchanger 73 after liquefaction. By providing the outdoor water receiving tray 74 below the outdoor heat exchanger 73 to collect the condensed water flowing down from the outdoor heat exchanger 73, it is possible to avoid outdoor dripping caused by the direct dripping of the condensed water. The outdoor water receiving tray 74 collects the condensed water for subsequent treatment of the condensed water.

[0108] As Figure 6 and Figure 7 shown in the figure, the air conditioner 100 includes: a second water pipe 65 and a second pumping device 64. The second pumping device 64 is disposed in the outdoor water receiving tray 74. One end of the second water pipe 65 is connected to the second pumping device 64, and the other end extends to the first water tank 31 for transporting the water in the outdoor water receiving tray 74 to the first water tank 31.

[0109] The second pumping device 64 and the second water pipe 65 transport the condensed water collected by the outdoor water receiving tray 74 to the first water tank 31 in the water storage part 21. That is to say, the condensed water collected by the indoor water receiving tray 12 and the condensed water collected by the outdoor water receiving tray 74 are both transported to the water storage part 21, and after being filtered by the filter element 4 in the water storage part 21, further processing is carried out.

[0110] In some embodiments of the present invention, as Figure 9 shown in the figure, the air conditioner 100 further includes: a second protection pipe 91, and the second protection pipe 91 is sleeved outside the second water pipe 65. The texture of the second water pipe 65 is relatively soft. A second protective sleeve is sleeved outside the second water pipe 65 to enhance the structural strength, protect the internal second water pipe 65, and improve the working reliability of the second water pipe.

[0111] As Figure 9 shown in the figure, the air conditioner 100 further includes: a second refrigerant pipe 92, and the second refrigerant pipe 92 and the second protection pipe 91 are bundled into a second heat transfer pipe group 90 through a second tightening member 94.

[0112] The second water pipe transports the condensed water on the outdoor side to the indoor side. When the external temperature is relatively low in winter, the condensed water in the second water pipe 65 may freeze and block. By the heat transfer cooperation between the second refrigerant pipe 92 and the second protection pipe 91, the heat of the second refrigerant pipe 92 is transferred to the second water pipe 65, which can avoid the freezing and blocking of the second water pipe 65 at a relatively low ambient temperature and improve the working reliability of the second water pipe 65 for transporting condensed water.

[0113] Moreover, the second refrigerant pipe 92 has relatively high structural strength. The second fastening member 94 binds the second refrigerant pipe 92 and the second protective pipe 91 into the second heat transfer pipe group 90, enhancing the overall structural strength of the second heat transfer pipe group 90, protecting the internal second water supply pipeline 65, and improving the working reliability of the second water supply pipe.

[0114] As Figure 7 and Figure 9 shown, the air conditioner 100 further includes: a second heat preservation pipe 93, and the second heat preservation pipe 93 is sleeved outside the second heat transfer pipe group 90. By providing the second heat preservation pipe 93, the internal second water supply pipeline 65 and the second refrigerant pipe 92 can be heat-insulated, reducing the influence of the ambient temperature on the second water supply pipeline 65 and the second refrigerant pipe 92.

[0115] In some embodiments of the present invention, a part of the refrigerant pipe of the air conditioner 100 is used as the second refrigerant pipe 92. By using the refrigerant pipe in the air conditioner 100 to exchange heat with the second water supply pipeline 65, the manufacturing cost of additionally arranging a refrigerant pipe can be saved.

[0116] In some embodiments of the present invention, the second fastening member 94 is a heat-shrinkable tube, and the heat-shrinkable tube is coated outside the second refrigerant pipe 92 and the second protective sleeve to form the second heat transfer pipe group 90.
