[0034] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A, or B, or, A and B.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0036] Combination Figure 1-4 As shown, an embodiment of the present disclosure provides an indoor unit 100 of an air conditioner, including a housing 1, an indoor heat exchanger 7, and a fan 8.

[0037] The housing 1 defines an air duct, and the indoor heat exchanger 7 and the fan 8 are located in the air duct. The housing 1 is provided with an air inlet and an air outlet 141, and the air inlet and the air outlet 141 are both connected to the air duct. Under the action of the fan 8, air enters the air duct from the air inlet, exchanges heat with the indoor heat exchanger 7, and is blown out from the air outlet 141 to achieve cooling or heating.

[0038] The shell 1 is provided with a first connection part 111 and a second connection part 114, and one of the first connection part 111 and the second connection part 114 is selectively connected to the installation base to realize the installation of the indoor unit 100 on the installation base. In other words, one of the first connection part 111 and the second connection part 114 is used to connect to the installation base, and the first connection part 111 is connected to the installation base, or the second connection part 114 is connected to the installation base. It is not necessary for both the first connection part 111 and the second connection part 114 to be connected to the installation base.

[0039] The installation base is a platform for installing the indoor unit 100. When the indoor unit 100 is installed on a wall, the installation base is the wall; when the indoor unit 100 is installed on a cabinet, the installation base is the cabinet.

[0040] The indoor unit 100 further includes at least one of a first water receiving pan 3 and a second water receiving pan 4 . The first water receiving pan 3 and the second water receiving pan 4 are suitable for being arranged on opposite sides of the indoor heat exchanger 7 and arranged in sequence along the direction from the first connection portion 111 to the second connection portion 114 .

[0041] The first water receiving tray 3 and the second water receiving tray 4 are sequentially arranged along the direction from the first connecting portion 111 to the second connecting portion 114. Figure 1 and Figure 2 As shown, when the indoor unit 100 is installed along the first direction, the first water receiving pan 3 is arranged below the indoor heat exchanger 7, and the condensed water generated by the indoor heat exchanger 7 drips to the first water receiving pan 3 under the action of gravity. At this time, the second connecting portion 114 can be connected to the installation base to ensure the approximate installation position of the indoor unit 100; Figure 3 and Figure 4 As shown, when the indoor unit 100 is installed along the second direction, the second water receiving pan 4 is arranged below the indoor heat exchanger 7, and the condensed water generated by the indoor heat exchanger 7 drips to the second water receiving pan 4 under the action of gravity. At this time, the first connecting portion 111 can be connected to the installation base to ensure the approximate installation position of the indoor unit 100. In this way, whether the indoor unit 100 is installed along the first direction or the second direction, the installation height of the indoor unit 100 on the installation base is consistent.

[0042] A first mounting position and a second mounting position are provided in the housing, and the indoor heat exchanger is located between the first mounting position and the second mounting position. The first mounting position and the second mounting position are sequentially arranged along the direction from the first connection portion to the second connection portion. When the indoor unit 100 includes the first water receiving pan 3 but does not include the second water receiving pan 4, the first water receiving pan 3 is arranged in the first mounting position; when the indoor unit 100 includes the second water receiving pan 4 but does not include the first water receiving pan 3, the second water receiving pan 4 is arranged in the second mounting position; when the indoor unit 100 includes the first water receiving pan 3 and the second water receiving pan 4, the first water receiving pan 3 is arranged in the first mounting position, and the second water receiving pan 4 is arranged in the second mounting position.

[0043] When the indoor unit 100 is installed in the first direction, the first water receiving tray 3 is arranged in the first installation position, the second water receiving tray 4 is arranged in the second installation position, or the second water receiving tray 4 is not arranged; when the indoor unit 100 is installed in the second direction, the second water receiving tray 4 is arranged in the second installation position, the first water receiving tray 3 is arranged in the first installation position, or the first water receiving tray 3 is not arranged.

[0044] Alternatively, if Figure 4 As shown, the first connection portion 111 and the second connection portion 114 are arranged along the up-down direction.

[0045] In this solution, the first water receiving pan 3 and the second water receiving pan 4 are arranged in the up and down direction, that is, one of the first water receiving pan 3 and the second water receiving pan 4 is arranged above the indoor heat exchanger 7, and the other of the first water receiving pan 3 and the second water receiving pan 4 is arranged below the indoor heat exchanger 7.

[0046] When installed in the first direction, the first water collecting pan 3 is located below the indoor heat exchanger 7, the second water collecting pan 4 is located above the indoor heat exchanger 7, and the first connecting part 111 is located below the second connecting part 114. At this time, the second connecting part 114 is connected to the installation base, and the first connecting part 111 is not connected to the installation base; when installed in the second direction, the second water collecting pan 4 is located below the indoor heat exchanger 7, the first water collecting pan 3 is located above the indoor heat exchanger 7, and the second connecting part 114 is located below the first connecting part 111. At this time, the first connecting part 111 is connected to the installation base, and the second connecting part 114 is not connected to the installation base.

[0047] Optionally, the air conditioner also includes an outdoor unit, which includes a compressor and an outdoor heat exchanger. The compressor, indoor heat exchanger 7 and outdoor heat exchanger are connected through a refrigerant pipe. The refrigerant flows in the compressor, indoor heat exchanger 7, outdoor heat exchanger and the refrigerant pipe to achieve cooling or heating of the air conditioner.

[0048] The indoor heat exchanger 7 is provided with a first refrigerant inlet and a second refrigerant inlet and an outlet. The directions in which the refrigerant flows through the indoor heat exchanger 7 are different in cooling and heating. Therefore, the refrigerant flows into the indoor heat exchanger 7 from one of the first refrigerant inlet and the second refrigerant inlet and an outlet, and flows out of the indoor heat exchanger 7 from the other of the first refrigerant inlet and the second refrigerant inlet and an outlet.

[0049] The refrigerant pipe includes a first inlet and outlet pipe 5 and a second inlet and outlet pipe 6. One end of the first inlet and outlet pipe 5 is connected to the first refrigerant inlet and outlet of the indoor heat exchanger 7, and the other end is connected to the outdoor heat exchanger; one end of the second inlet and outlet pipe 6 is connected to the second refrigerant inlet and outlet of the indoor heat exchanger 7, and the other end is connected to the compressor.

[0050] The first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6 are usually arranged on the right side or the left side of the indoor unit 100. Taking the first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6 being arranged on the right side of the indoor unit 100 as an example, sometimes the right side of the user's installation space cannot be directly installed, so the refrigerant pipe needs to go around the indoor unit 100 and then exit the pipe, which increases the length of the refrigerant pipe and increases the cost. Alternatively, if the refrigerant pipe does not go around the indoor unit 100, it needs to be forced to run the pipe, which will damage the wall and cause the inspection port of the indoor unit 100 to be blocked by the wall.

[0051] In the present application, the first direction is right-side installation, and the second direction is left-side installation. When the right-side installation is possible, the first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6 are located on the right side of the indoor unit 100. When the right-side installation is not possible and the left-side installation is required, the indoor unit 100 is rotated 180° in the vertical plane, and the first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6 are located on the left side of the indoor unit 100.

[0052] Therefore, in the present application, the first connection part 111 and the second connection part 114 are arranged in the up and down direction, and the first water receiving tray 3 and the second water receiving tray 4 are arranged in the up and down direction, which can not affect the arrangement of the first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6, and there is no need to force the pipe to damage the wall, nor is there a need for the first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6 to go around the indoor unit 100.

[0053] Optionally, the indoor unit 100 further includes a hanging foot 2, the hanging foot 2 is provided with a first connecting fitting portion 21 and a second connecting fitting portion 22, the first connecting portion 111 and the second connecting portion 114 are selectively connected to the first connecting fitting portion 21, and the second connecting fitting portion 22 is used to connect to the installation base.

[0054] One of the first connection part 111 and the second connection part 114 is selectively connected to the first connection matching part 21. In other words, one of the first connection part 111 and the second connection part 114 is used to connect to the first connection matching part 21, and the first connection part 111 is connected to the first connection matching part 21, or the second connection part 114 is connected to the first connection matching part 21. It is not necessary for both the first connection part 111 and the second connection part 114 to be connected to the first connection matching part 21.

[0055] The first connection part 111 or the second connection part 114 is connected to the first connection matching part 21 to realize the connection between the hanging foot 2 and the shell 1, and the second connection matching part 22 is connected to the installation base to realize the connection between the hanging foot 2 and the installation base, thereby realizing the installation of the indoor unit 100 on the installation base through the hanging foot 2.

[0056] The hanging foot 2 and the housing 1 can be screw-connected and / or snap-fitted. The first connecting portion 111 and the second connecting portion 114 can both include a first screw hole 1111 and a first snap-fitting groove, and the first connecting matching portion 21 includes a second screw hole 211 matched with the first screw hole 1111 and a first snap-fitting groove matched with the first snap-fitting groove. The screw passes through the first screw hole 1111 and the second screw hole 211, and the first snap-fitting groove is inserted into the first snap-fitting groove, so as to realize the screw connection and snap-fitting of the housing 1 and the hanging foot 2.

[0057] The hanging foot 2 and the installation base can be connected by screws and / or clamping, or by other connection methods, such as connection through a connecting rod.

[0058] Either the first connection portion 111 or the second connection portion 114 is detachably connected to the first connection matching portion 21 .

[0059] In this way, the number of the hanging feet 2 can be equal to the number of the first connecting parts 111 or the number of the second connecting parts 114 , but does not need to be equal to the sum of the first connecting parts 111 and the second connecting parts 114 .

[0060] like Figure 1 and Figure 2 As shown, when the indoor unit 100 needs to be installed in the first direction, the hanging foot 2 is connected to the second connecting portion 114; Figure 3 and Figure 4 As shown, when the second direction installation is required, the hanging foot 2 is connected to the first connecting portion 111 .

[0061] The first connection portion 111 and the second connection portion 114 are identical, so that the same hanging leg 2 can be connected to both the first connection portion 111 and the second connection portion 114 .

[0062] It is understandable that the number of the hanging feet 2 may be equal to the total number of the first connection part 111 and the second connection part 114 , so that the first connection part 111 is equipped with a hanging foot 2 , and the second connection part 114 is also equipped with a hanging foot 2 .

[0063] Alternatively, if Figures 1 to 4 As shown, the housing 1 includes a first side wall 11 , a second side wall, a third side wall and a fourth side wall 14 .

[0064] The first connection part 111 and the second connection part 114 are both arranged on the first side wall 11, and one of the first connection part and the second connection part is arranged at the top of the first side wall, and the other is arranged at the bottom of the first side wall. Specifically, when the indoor unit is installed in the first direction, the second connection part is located at the top of the first side wall, and the first connection part is located at the bottom of the first side wall; when the indoor unit is installed in the second direction, the first connection part is located at the top of the first side wall, and the second connection part is located at the bottom of the first side wall; the second side wall is arranged opposite to the first side wall 11; the third side wall is connected between one end of the first side wall 11 and one end of the second side wall; the fourth side wall 14 is connected between the other end of the first side wall 11 and the other end of the second side wall.

[0065] The housing 1 further includes a top wall 15 and a bottom wall 16. When the indoor unit 100 is installed in the first direction, the top wall 15 is arranged above the first side wall 11, the second side wall, the third side wall and the fourth side wall 14, and the bottom wall 16 is arranged below the first side wall 11, the second side wall, the third side wall and the fourth side wall 14. When the indoor unit 100 is installed in the second direction, the top wall 15 is arranged below the first side wall 11, the second side wall, the third side wall and the fourth side wall 14, and the bottom wall 16 is arranged above the first side wall 11, the second side wall, the third side wall and the fourth side wall 14.

[0066] Among them, Figures 1 to 3 As shown, the third side wall is provided with an air inlet and the fourth side wall 14 is provided with an air outlet 141 , or the third side wall is provided with an air inlet and an air outlet 141 , or the fourth side wall 14 is provided with an air inlet and an air outlet 141 .

[0067] When the indoor unit 100 is installed in the first direction or the second direction, the relative positions of the third side wall and the fourth side wall 14 do not change, and the third side wall is still located in front of the fourth side wall 14. Therefore, the air inlet is arranged on the third side wall, and the air outlet 141 is arranged on the fourth side wall 14. Regardless of whether the indoor unit 100 is installed in the first direction or the second direction, the air intake of the air inlet and the air outlet of the air outlet 141 are not affected.

[0068] Alternatively, the third side wall or the fourth side wall 14 is provided with an air inlet and an air outlet 141 , and no matter whether the indoor unit 100 is installed in the first direction or the second direction, the air intake of the air inlet and the air outlet 141 are not affected.

[0069] Optionally, the first water receiving tray 3 is detachably connected to the housing 1 .

[0070] In this way, when the indoor unit 100 is installed in the second direction, the first water receiving tray 3 can be removed to reduce the cost of the indoor unit 100.

[0071] The detachable connection can be a snap connection, a plug connection or a screw connection, etc.

[0072] Optionally, the second water receiving tray 4 is detachably connected to the housing 1 .

[0073] In this way, when the indoor unit 100 is installed in the first direction, the second water receiving tray 4 can be removed to reduce the cost of the indoor unit 100.

[0074] The detachable connection can be a snap connection, a plug connection or a screw connection, etc.

[0075] Optionally, the shell 1 is provided with a first plug port and a second plug port, the first plug port corresponds to the first water receiving tray 3, the first water receiving tray 3 can be taken out of the shell 1 or inserted into the shell 1 through the first plug port, and the second water receiving tray 4 can be taken out of the shell 1 or inserted into the shell 1 through the second plug port.

[0076] Optionally, the first side wall 11 is provided with a first through hole 112, the first inlet and outlet liquid pipe 5 is inserted into the shell 1 through the first through hole 112 and is connected to the first refrigerant inlet and outlet of the indoor heat exchanger 7; the second inlet and outlet liquid pipe 6 is inserted into the shell 1 through the first through hole 112 and is connected to the second refrigerant inlet and outlet of the indoor heat exchanger 7.

[0077] like Figures 1 to 3As shown, the first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6 are both arranged on the first side wall 11. When installed in the first direction and the second direction, the first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6 do not need to go around the indoor unit 100. Moreover, the first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6 are both arranged on the first side wall 11. The installer can complete the connection of the first inlet and outlet liquid pipe 5 and the second inlet and outlet liquid pipe 6 on one side without changing the position, thereby improving the connection efficiency.

[0078] Optionally, the shape and size of the first water receiving tray 3 are respectively the same as the shape and size of the second water receiving tray 4 .

[0079] The shape of the first water receiving tray 3 is the same as that of the second water receiving tray 4, and the size of the first water receiving tray 3 is the same as that of the second water receiving tray 4. This allows the first water receiving tray 3 and the second water receiving tray 4 to be used interchangeably, reduces mold opening costs, and prevents the first water receiving tray 3 and the second water receiving tray 4 from being installed incorrectly.

[0080] Optionally, the first water receiving tray 3 includes a first tray body and a first drainage interface 32 connected to the first tray body; the second water receiving tray 4 includes a second tray body 41 and a second drainage interface 42 connected to the second tray body 41 .

[0081] The housing 1 is provided with a second through hole 113 , and the first drainage interface 32 and the second drainage interface 42 pass through the second through hole 113 to the outside of the housing 1 .

[0082] The first plate body and the second plate body 41 are used to receive condensed water.
