It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the embodiments of the present application. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0030] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0031] An air conditioner generally uses a compressor to circulate a heat exchange medium between heat exchangers to achieve refrigeration or heating. During the operation of the air conditioner, condensate will inevitably be generated. The water receiving tray is a structure in the air conditioner for storing and draining water, and is generally arranged below the evaporator to receive and drain the condensate.

[0032] In the related art, generally, a water pump is used to pump the condensate in the water receiving tray to the outdoor unit for treatment, or the condensate in the water receiving tray is drained through a drain hole communicating with a drain pipe. The water in the water receiving tray cannot be drained completely, is easy to remain, and the accumulated water is easy to mildew, resulting in peculiar smell in the air conditioner.

[0033] Based on the above situation, in the first aspect of the embodiments of the present application, an indoor unit 10 of an air conditioner is provided. Please refer to Figures 1 to 6 , the indoor unit 10 of the air conditioner includes a heat exchanger 11, a water receiving tray 12, and a first heat exchange pipeline 13. The water receiving tray 12 has a water receiving groove 12a. The water receiving tray 12 is arranged below the heat exchanger 11. The first heat exchange pipeline 13 is used for the heat exchange medium to flow through. The first heat exchange pipeline 13 includes a first medium pipeline 131, a second medium pipeline 132, and a third medium pipeline 133. The first medium pipeline 131 and the second medium pipeline 132 are respectively connected to the heat exchanger 11. Both ends of the third medium pipeline 133 are connected to the first medium pipeline 131 and the second medium pipeline 132. The third medium pipeline 133 can selectively dry the water receiving groove 12a.

[0034] It should be noted that the indoor unit 10 of the air conditioner provided by the embodiments of the present application can be a duct type air conditioner, a wall-mounted indoor unit of an air conditioner, or a ceiling-mounted indoor unit of an air conditioner, which is not limited herein.

[0035] The water receiving tray 12 has a water receiving groove 12a. Specifically, the water receiving tray 12 can be sunken to form the water receiving groove 12a.

[0036] Among them, the water receiving groove 12a is used to concentrate the condensed water in the water receiving tray 12.

[0037] Exemplarily, the water receiving tray 12 also has a drain hole, and the drain hole is used to drain the condensed water in the water receiving tray 12.

[0038] The water receiving tray 12 is arranged below the heat exchanger 11, so that the condensed water generated by the heat exchanger 11 can directly reach the water receiving tray 12, which is beneficial to the collection of the condensed water.

[0039] The first medium pipeline 131 and the second medium pipeline 132 are respectively communicated with the heat exchanger 11, which means that one of the first medium pipeline 131 and the second medium pipeline 132 is communicated with the inlet of the heat exchanger 11, and the other is communicated with the outlet of the heat exchanger 11.

[0040] Among them, one ends of the first medium pipeline 131 and the second medium pipeline 132 are respectively communicated with the heat exchanger 11, and the other ends are respectively communicated with the air conditioner outdoor unit.

[0041] Exemplarily, the first medium pipeline 131 is a high-pressure pipe, and the second medium pipeline 132 is a low-pressure pipe.

[0042] Both ends of the third medium pipeline 133 are respectively communicated with the first medium pipeline 131 and the second medium pipeline 132. That is to say, the third medium pipeline 133 is connected in parallel with the heat exchanger 11.

[0043] The third medium pipeline 133 can selectively dry the water receiving groove 12a. It can be that a part of the third medium pipeline 133 is close to the water receiving groove 12a, and by selectively conducting the third medium pipeline 133, the heat exchange medium flows through the third medium pipeline 133 to realize drying of the water receiving groove 12a.

[0044] Exemplarily, when the air conditioner switches from the cooling mode to the shutdown mode, the air conditioner detects the duration of the user using the cooling mode. If the cooling duration meets the preset duration, the air conditioner enters the water receiving tray drying mode. At this time, the air conditioner operates in heating for a certain time, and the high-temperature heat exchange medium is introduced into the third medium pipeline 133, and the condensed water remaining in the water receiving groove 12a is evaporated through the third medium pipeline 133 to dry the water receiving tray 12.

[0045] The indoor air conditioner 10 provided by the embodiment of the present application enables the first medium pipeline 131 and the second medium pipeline 132 to be respectively communicated with the heat exchanger 11, and at the same time, both ends of the third medium pipeline 133 are respectively communicated with the first medium pipeline 131 and the second medium pipeline 132, so that the third medium pipeline 133 is in parallel with the heat exchanger 11. In this way, the heat exchange medium can be selectively introduced into the third medium pipeline 133 or the heat exchanger 11. When the indoor air conditioner 10 works normally, the heat exchanger 11 is turned on, and when the water receiving tray 12a needs to be dried, the third medium pipeline 133 is turned on, so as to realize drying of the water receiving tray 12a by the third medium pipeline 133, and the moisture remaining in the water receiving tray 12a after the normal operation of the indoor air conditioner 10 is evaporated, improving the situation that the air conditioner generates peculiar smell due to the condensation water remaining in the water receiving tray 12.

[0046] In some embodiments, please refer to Figure 2 and Figure 4 , the third medium pipeline 133 includes a main body section 133a and a connecting section 133b. The connecting section 133b extends along the height direction of the indoor air conditioner 10. One end of the connecting section 133b is connected to the main body section 133a, and the other end is connected to the first medium pipeline 131 or the second medium pipeline 132.

[0047] It should be noted that in the third medium pipeline 133, the main body section 133a is mainly used for drying the water receiving tray 12a.

[0048] One end of the connecting section 133b is connected to the main body section 133a, and the other end is connected to the first medium pipeline 131 or the second medium pipeline 132. That is to say, the connecting section 133b can be used as an intermediate transition to indirectly connect the main body section 133a to the first medium pipeline 131 and / or the second medium pipeline 132.

[0049] The connecting section 133b extends along the height direction of the indoor air conditioner 10, so that the main body section 133a of the third medium pipeline 133 is arranged below the heat exchanger 11 along the height direction, close to the position of the water receiving tray 12a, which is beneficial to drying the water receiving tray 12a by the third medium pipeline 133.

[0050] It can be understood that the main body section 133a can be connected to one of the first medium pipeline 131 and the second medium pipeline 132 through the connecting section 133b, and the main body section 133a can also be directly connected to the first medium pipeline 131 or the second medium pipeline 132.

[0051] Exemplarily, the number of the connecting sections 133b is one. One end of the main body section 133a is connected to the second medium pipeline 132 through the connecting section 133b, and the other end of the main body section 133a is directly connected to the first medium pipeline 131.

[0052] Exemplarily, the number of the connecting sections 133b can be two. One end of the main body section 133a is connected to the second medium pipeline 132 through the connecting section 133b, and the other end is connected to the first medium pipeline 131 through the connecting section 133b.

[0053] Thus, by connecting one end of the connecting section 133b to the main body section 133a and the other end to the first medium pipeline 131 or the second medium pipeline 132, the main body section 133a is indirectly connected to the first medium pipeline 131 or the second medium pipeline 132. The main body section 133a can be arranged below the heat exchanger 11 along the height direction, close to the water receiving tank 12a, which is beneficial to drying the water receiving tank 12a by the third medium pipeline 133, making the structure of the third medium pipeline 133 more reasonable.

[0054] In some embodiments, please refer to Figures 1 to 4 , the heat exchanger 11 has adjacent first side 11a and second side 11b. The first medium pipeline 131 and the second medium pipeline 132 are located on the first side 11a of the heat exchanger 11. Part of the main body section 133a is located on the first side 11a of the heat exchanger 11 and is respectively communicated with the first medium pipeline 131 and the second medium pipeline 132, and part of the main body section 133a is located on the second side 11b of the heat exchanger 11.

[0055] It should be noted that the heat exchanger 11 has adjacent first side 11a and second side 11b, wherein the first side 11a is the side of the inlet and outlet of the heat exchanger 11, so that the first medium pipeline 131 and the second medium pipeline 132 on the first side 11a are closer to the inlet and outlet of the heat exchanger 11, facilitating pipeline connection.

[0056] Part of the main body section 133a is located on the first side 11a of the heat exchanger 11 and is respectively communicated with the first medium pipeline 131 and the second medium pipeline 132. It can be that the main body section 133a is communicated with the first medium pipeline 131 or the second medium pipeline 132 through the connecting section 133b, or the main body section 133a is directly communicated with the first medium pipeline 131 or the second medium pipeline 132.

[0057] Part of the main body section 133a is located on the second side 11b of the heat exchanger 11, that is to say, the main body section 133a extends from the first side 11a communicated with the first medium pipeline 131 and the second medium pipeline 132 to the second side 11b, so that the length of the main body section 133a is longer, which can increase the heat exchange area and is beneficial to improving the drying effect on the water receiving tray 12.

[0058] Exemplarily, the air conditioner indoor unit 10 is in the shape of a cuboid. The heat exchanger 11 is arranged along the length direction of the air conditioner indoor unit 10. The water receiving tray 12 is located below the heat exchanger 11 and correspondingly arranged along the length direction of the air conditioner indoor unit 10 as well. The first side 11a of the heat exchanger 11 is located at one end of the length direction of the air conditioner indoor unit 10. The main body section 133a extends from the first side 11a of the heat exchanger 11 to the second side 11b and extends to the other end of the length direction of the air conditioner indoor unit 10.

[0059] Here, by arranging a part of the main body section 133a on the first side 11a of the heat exchanger 11 where the first medium pipeline 131 and the second medium pipeline 132 are located and communicating with the first medium pipeline 131 and the second medium pipeline 132 respectively, the connection of the pipelines is more convenient. At the same time, a part of the main body section 133a is located on the second side 11b of the heat exchanger 11, which can increase the heat exchange area and is beneficial to improving the drying effect on the water receiving tray 12.

[0060] In some embodiments, the main body section 133a is arranged at an interval from the water receiving groove 12a, or; the main body section 133a is in contact with the water receiving groove 12a.

[0061] The main body section 133a being arranged at an interval from the water receiving groove 12a means that there is a gap between the main body section 133a and the water receiving groove 12a.

[0062] It should be noted that it can be that a part of the main body section 133a is arranged at an interval from the water receiving groove 12a and another part of the main body section 133a is in contact with the water receiving groove 12a.

[0063] By arranging the main body section 133a at an interval from the water receiving groove 12a or making the main body section 133a in contact with the water receiving groove 12a, the distance between the main body section 133a and the water receiving groove 12a is closer, which can improve the heat exchange efficiency and further improve the drying effect on the water receiving groove 12a.

[0064] In some embodiments, the water receiving groove 12a is recessed to form a groove, and at least a part of the main body section 133a is arranged in the groove.

[0065] It should be noted that the water receiving groove 12a is recessed towards one end away from the heat exchanger 11 along the height direction of the air conditioner indoor unit 10 to form a groove.

[0066] At least a part of the main body section 133a is arranged in the groove, wherein the main body section 133a can be in contact with or arranged at an interval from the groove.

[0067] Here, by disposing at least a part of the main body section 133a in the groove, it is beneficial to increase the contact area or heat exchange area between the main body section 133a and the water receiving tank 12a, thereby further enhancing the drying effect on the water receiving tank 12a. At the same time, it can also make the third medium pipeline 133 and the water receiving tank 12a more compact, improving the utilization rate of the internal space of the indoor air conditioner.

[0068] In some embodiments, the distance between at least a part of the main body section 133a and the water receiving tray 12 does not exceed 4 mm. Exemplarily, the distance can be 4 mm, 3.5 mm, 3 mm, 2.5 mm, 2 mm, 1.5 mm, 1 mm, 0.5 mm or 0.1 mm, etc.

[0069] It can be understood that the smaller the distance between the main body section 133a and the water receiving tray 12, the higher the heat exchange efficiency between the main body section 133a and the water receiving tank 12a, and the better the drying effect of the main body section 133a on the water receiving tank 12a.

[0070] By arranging at least a part of the main body section 133a and the water receiving tray 12 at intervals, and the distance between at least a part of the main body section 133a and the water receiving tray 12 does not exceed 4 mm, the heat exchange efficiency and the drying effect are further improved.

[0071] In some embodiments, please refer to Figures 1 to 6 , the indoor unit 10 of the air conditioner includes a first valve 14 and a second valve 15. The first valve 14 and the second valve 15 are respectively disposed at both ends of the third medium pipeline 133 for selectively conducting or closing the third medium pipeline 133.

[0072] It should be noted that the first valve 14 and the second valve 15 can be disposed on the main body section 133a or the connecting section 133b.

[0073] Exemplarily, the first valve 14 and the second valve 15 are only used to close or conduct the third medium pipeline 133, so they will not be disposed on the first medium pipeline 131 and the second medium pipeline 132.

[0074] Thus, by disposing the first valve 14 and the second valve 15 at both ends of the third medium pipeline 133, the closing and conducting of the third medium pipeline 133 can be flexibly controlled, thereby improving the utilization efficiency of the heat exchange medium.

[0075] In some embodiments, please refer to Figures 1 to 6, the indoor air conditioner 10 includes a third valve 16, a fourth valve 17, a first connecting pipe 18, and a second connecting pipe 19. The third valve 16 is disposed on the first connecting pipe 18. The fourth valve 17 is disposed on the second connecting pipe 19. The first medium pipeline 131 communicates with the heat exchanger 11 through the first connecting pipe 18. The second medium pipeline 132 communicates with the heat exchanger 11 through the second connecting pipe 19.

[0076] It should be noted that the first connecting pipe 18 is a transition connecting pipe between the heat exchanger 11 and the first medium pipeline 131, and the second connecting pipe 19 is a transition connecting pipe between the heat exchanger 11 and the second medium pipeline 132.

[0077] By respectively disposing the third valve 16 and the fourth valve 17 on the first connecting pipe 18 and the second connecting pipe 19, when the third medium pipeline 133 is conducted and the water receiving tray 12 is dried, the heat exchange medium is prevented from entering the heat exchanger 11, and the heat exchange medium is all introduced into the third medium pipeline 133 as much as possible, thereby improving the drying efficiency of the heat exchange medium for the water receiving tray 12 and realizing rapid drying.

[0078] A second aspect of the embodiments of the present application provides an air conditioner. Please refer to Figures 5 to 6 , the air conditioner includes an outdoor air conditioner and the indoor air conditioner 10 provided in any embodiment of the present application. The outdoor air conditioner includes a second heat exchange pipeline. The second heat exchange pipeline communicates with the first heat exchange pipeline 13 to form a flow path for the heat exchange medium to flow through.

[0079] In the air conditioner provided by the embodiments of the present application, by respectively communicating the first medium pipeline 131 and the second medium pipeline 132 of the indoor air conditioner 10 with the heat exchanger 11, and at the same time, both ends of the third medium pipeline 133 are respectively communicated with the first medium pipeline 131 and the second medium pipeline 132, so that the third medium pipeline 133 is in parallel with the heat exchanger 11. In this way, the heat exchange medium is selectively introduced into the third medium pipeline 133 or the heat exchanger 11. When the indoor air conditioner 10 operates normally, the heat exchanger 11 is conducted. When the water receiving tank 12a needs to be dried, the third medium pipeline 133 is conducted, so as to realize the drying of the water receiving tank 12a by the third medium pipeline 133, and the water remaining in the water receiving tank 12a after the normal operation of the indoor air conditioner 10 evaporates, improving the situation that the air conditioner generates peculiar smell due to the condensation water remaining in the water receiving tray 12.

[0080] In some embodiments, please refer to Figure 5 , the flow path has a first sub-path. The air conditioner has a first state. In the first state, the first valve 14 and the second valve 15 are disconnected. The third valve 16 and the fourth valve 17 are conducted. The second heat exchange pipeline, the first medium pipeline 131, the heat exchanger 11, and the second medium pipeline 132 are communicated to form a first sub-path.

[0081] It should be noted that the first state can be a refrigeration mode or other working modes.

[0082] In the first state, the first sub-path through which the heat exchange medium flows is as Figure 5 shown by the arrow in

[0083] Exemplarily, when the first state is the refrigeration mode, the first medium pipeline 131 is a high-pressure pipe, and the second medium pipeline 132 is a low-pressure pipe.

[0084] In the first state, by disconnecting the first valve 14 and the second valve 15, the third medium pipeline 133 is disconnected, and the heat exchange medium of the air conditioner is introduced into the heat exchanger 11, so that the air conditioner enters the normal working state.

[0085] In some embodiments, please refer to Figure 6 , the flow path has a second sub-path. The air conditioner has a second state. In the second state, the first valve 14 and the second valve 15 are conducting, and the third valve 16 and the fourth valve 17 are disconnected. The second heat exchange pipeline, the second medium pipeline 132, the third medium pipeline 133 and the first medium pipeline 131 are connected to form a second sub-path. The third medium pipeline 133 can dry the water receiving tray 12.

[0086] It should be noted that the second state is the mode of drying the water receiving tray.

[0087] In the second state, the second sub-path through which the heat exchange medium flows is as Figure 6 shown by the arrow in

[0088] Specifically, if the duration of the first state is greater than or equal to a preset duration, after the air conditioner shuts down from the first state, the air conditioner automatically enters the second state.

[0089] Exemplarily, the preset duration is five minutes, and the first state is the refrigeration state. Then the air conditioner enters the second state for one minute. In the second state, the outdoor unit of the air conditioner performs heating, so that the high-temperature heat exchange medium is introduced into the third medium pipeline 133 to quickly dry the water receiving tray 12.

[0090] It should be noted that the air conditioner can also be directly controlled to enter the second state to forcibly and quickly dry the water receiving tray 12, thereby increasing the application range of the mode of drying the water receiving tray. For example, it is applicable to the situation where there is accumulated water on the water receiving tray 12 when the refrigeration is not running.

[0091] Thus, after the first state ends, the second state is automatically entered according to the running duration of the first state, so that the first valve 14 and the second valve 15 are conducted, and the third valve 16 and the fourth valve 17 are disconnected, thereby disconnecting the heat exchanger 11 and conducting the third medium pipeline 133, and the heat exchange medium of the air conditioner is introduced into the third medium pipeline 133, so as to selectively dry the water receiving tray 12.

[0092] In the description of the present application, the description referring to terms such as "an embodiment", "some embodiments", "examples", "specific examples", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application.
