[0033] Figure 1 This is a schematic structural diagram of an indoor unit according to an embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 4 The present invention provides an indoor unit 100 including a housing 10, a water receiving tray 20, and a water pump 30. The water receiving tray 20 is disposed within the housing 10 and is used to receive condensed water generated by the heat exchanger 70. The water receiving tray 20 has an outlet 210. The water pump 30 has a water inlet 310 connected to the outlet 210 via a connecting hose 40.

[0034] In this embodiment, the water pump 30 is connected to the water receiving tray 20 via a connecting hose 40. When the water pump 30 and the water receiving tray 20 are connected, the water pump 30 can be moved. When repairing or replacing the water pump 30, the structure that fixes the water pump 30 is removed, and the position of the water pump 30 can be moved. After the water pump 30 is moved to a place with a larger space or a place that is convenient for operation, the water pump 30 can be repaired or replaced. When installing the water pump 30, the water pump 30 and the water receiving tray 20 can be connected first, and then the water pump 30 can be placed in a suitable position and fixed. Since the pipe between the water pump 30 and the water receiving tray 20 is a hose, the water pump 30 can be pulled to a position that is convenient for repair or replacement, thereby facilitating the repair or replacement of the water pump 30 and improving the efficiency of repair or replacement of the water pump 30.

[0035] In some embodiments of the present invention, the housing 10 has an opening on the front side. The length of the connecting hose 40 is greater than the distance from the outlet 210 to the opening, so that when the connecting hose 40 connects the water tray 20 and the water pump 30, the water pump 30 can extend from the housing 10 through the opening.

[0036] In this embodiment, the length of the connecting hose 40 is greater than the distance from the outlet 210 of the water receiving tray 20 to the opening. To repair or replace the water pump 30, the structure securing the water pump 30 is removed, and the water pump 30 is then pulled toward the opening, removed from the housing 10, and removed for replacement. Repairing the water pump 30 only requires pulling the water pump 30 out for repair. When installing the water pump 30, the water pump 30 can be connected to the hose outside the indoor unit 100 and then placed inside the indoor unit 100 for securement. Because the connecting pipe between the water pump 30 and the water receiving tray 20 is a hose, the water pump 30 can be pulled out of the indoor unit 100 for repair or replacement. This allows for easy access to the outside of the indoor unit 100 for repair or replacement.

[0037] In some embodiments of the present invention, Figure 2 As shown, the height of the outlet 210 is higher than the height of the water inlet 310 .

[0038] In this embodiment, the height of the outlet 210 of the water receiving tray 20 is higher than the height of the water inlet 310 of the water pump 30. Due to the height difference between the outlet 210 and the water inlet 310, the condensed water flows downward under the action of gravity, which is conducive to the condensed water in the water receiving tray 20 to flow toward the water pump 30 during drainage, facilitating the drainage of the water receiving tray 20 and improving the drainage efficiency of the water pump 30.

[0039] In some embodiments of the present invention, Figure 1 As shown, the water pump 30 is disposed at a corner position at the lower front side of the housing 10 .

[0040] In this embodiment, the water pump 30 is disposed in a front lower corner of the indoor unit 100. The water pump 30 is close to the front opening, making it easy to pull the water pump 30 out of the indoor unit 100, thereby facilitating repair or replacement of the water pump 30. Furthermore, the placement of the water pump 30 in a corner of the indoor unit 100 effectively utilizes the internal space of the indoor unit 100, thereby reducing the size of the indoor unit 100 or increasing the space available for other components of the indoor unit 100, thereby reducing the production cost of the indoor unit 100 or improving the performance of the indoor unit 100.

[0041] In some embodiments of the present invention, Figure 2 As shown, the water pump 30 further has a water outlet 320 , which is disposed above the water inlet 310 , and the water inlet 310 and the water outlet 320 face rearward or to the rear side.

[0042] In this embodiment, the water outlet 320 and water inlet 310 of the water pump 30 are positioned rearward or laterally, with the water inlet 310 and water outlet 320 facing the outlet 210 of the water tray 20. This prevents the connecting hose 40 from folding when the water pump 30 is connected to the water tray 20, ensuring a smooth and uniform flow of condensed water, maintaining water pressure and facilitating condensed water discharge. Furthermore, the condensed water flows along the wall of the connecting hose 40, minimizing the impact of the condensed water on the connecting hose 40, preventing damage to the water pump 30 and the connecting hose 40 and increasing the service life of the water pump 30.

[0043] In some embodiments of the present invention, Figure 1 As shown, the water pump 30 is mounted on the housing 10 via a mounting bracket 50. The mounting bracket 50 includes a first mounting portion 510, a second mounting portion 520, and a connecting portion 530. The first mounting portion 510 is horizontally disposed, and the water pump 30 is connected to the first mounting portion 510 via screws. The second mounting portion 520 is vertically disposed and connected to the housing 10 via screws. The connecting portion 530 connects the first mounting portion 510 and the second mounting portion 520. The connecting portion 530 is vertically disposed and perpendicular to the first mounting portion 510 and the second mounting portion 520.

[0044] In this embodiment, the water pump 30 is fixed to the housing 10 via a mounting bracket 50. The mounting bracket 50 includes a first mounting portion 510, a second mounting portion 520, and a connecting portion 530. The connecting portion 530 connects the first mounting portion 510 and the second mounting portion 520. The first mounting portion 510 is used to fix the water pump 30. The first mounting portion 510 is placed above the water pump 30 and is fixed to the first mounting portion 510 and the water pump 30 by screws. The second mounting portion 520 is used to connect to the housing 10 and is connected to the second mounting portion 520 and the housing 10 by screws. When installing the water pump 30, the water pump 30 is fixed to the mounting bracket 50, and then the mounting bracket 50 is connected to the housing 10. The provision of the mounting bracket 50 facilitates the installation and removal of the water pump 30. The screw connection method is also adopted, and the connection is stable and reliable, preventing the water pump 30 from shaking significantly during operation.

[0045] In some embodiments of the present invention, Figure 4 As shown, the first mounting portion 510 is provided with a positioning hole 512 and a plurality of mounting slots 511. The water pump 30 is provided with a plurality of mounting holes corresponding to the mounting slots 511. Screws pass through the mounting slots 511 and the mounting holes to secure the water pump 30 to the mounting bracket 50. The connecting portion 530 includes a first connecting portion 531 and a second connecting portion 532. The length of the first connecting portion 531 is shorter than that of the second connecting portion 532. Two second mounting portions 520 are provided, and the two second mounting portions 520 are respectively connected to the first connecting portion 531 and the second connecting portion 532.

[0046] In this embodiment, the first mounting portion 510 is provided with a positioning hole 512. When securing the water pump 30, it mates with the shape of the upper portion of the water pump 30 housing, preventing a gap between the first mounting portion 510 and the water pump 30, thereby making the connection between the water pump 30 and the first mounting portion 510 more secure and reliable. The connecting portion 530 includes a first connecting portion 531 and a second connecting portion 532 connected at the top, with a gap between the lower portion of the first connecting portion 531 and the lower portion of the second connecting portion 532. When connected to the housing 10, the connecting portion 530 occupies less space and can mate with the shape of the housing 10, avoiding a portion of the housing 10, thereby facilitating the securing of the water pump 30 to the housing 10. Furthermore, the first connecting portion 531 and the second connecting portion 532 can be of different lengths, aligning the shape of the connecting portion 530 with the housing 10, preventing a gap between the connecting portion 530 and the housing 10, and further making the connection between the mounting structure and the housing 10 more secure and reliable.

[0047] In some other embodiments of the present invention, the connecting portion 530 is square, and the second mounting portion 520 is connected to the front and rear sides of the connecting portion 530 .

[0048] In this embodiment, the connecting portion 530 is square, i.e., the first connecting portion 531 and the second connecting portion 532 are connected together, and both sides of the connecting portion 530 are connected to the second mounting portion 520. The connecting portion 530 has a relatively stable structure. The water pump 30 has its own weight, and vibrations generated during operation of the water pump 30 may cause deformation of the connecting portion 530. The relatively strong structure of the connecting portion 530 prevents deformation of the connecting portion 530 from damaging the water pump 30 or other structures, thereby improving the stability of the mounting bracket 50 and making the connection between the water pump 30 and the housing 10 more secure and reliable.

[0049] In some embodiments of the present invention, Figure 1 As shown, the indoor unit 100 further includes a heat exchanger 70 and a liquid distribution pipe 80 . The liquid distribution pipe 80 is connected to the heat exchanger 70 and is a hose.

[0050] In this embodiment, the indoor unit 100 further includes a heat exchanger 70, to which a liquid distribution pipe 80 is connected. The liquid distribution pipe 80 is used to transport refrigerant from the outdoor unit to the heat exchanger 70 in the indoor unit 100. The liquid distribution pipe 80 is a flexible pipe. When installing the air conditioner, the liquid distribution pipe 80 can be connected to other pipes at a convenient location. The liquid distribution pipe 80 can also be bent to adjust the position and angle of the connection of the liquid distribution pipe 80 to facilitate alignment with the connection of the liquid distribution pipe 80 with the other pipes. This makes connecting the internal pipes of the indoor unit 100 more convenient, thereby facilitating installation of the air conditioner.

[0051] In some embodiments of the present invention, the indoor unit 100 further includes a heat exchanger 70 and an electrical box 90 . A heat exchange elbow 710 extends from one side of the heat exchanger 70 , and the electrical box 90 is disposed above the heat exchange elbow 710 .

[0052] In this embodiment, a heat exchange elbow 710 is connected to one side of the heat exchanger 70, which enables the refrigerant to flow through the heat exchanger 70. A relatively small free space is formed above the heat exchange elbow 710, making it suitable for the smaller electrical box 90. Placing the electrical box 90 within this free space rationally utilizes the internal space of the indoor unit 100, effectively saving space within the indoor unit 100. This reduces the size of the indoor unit 100 or allows for more space to be used by other components within the indoor unit 100, thereby reducing the production cost of the indoor unit 100 or improving its performance.

[0053] In some embodiments of the present invention, Figures 1 to 3 As shown, the indoor unit 100 further includes a heat exchanger 70 and an electrical box 90 , and the electrical box 90 is disposed above the heat exchanger 70 .

[0054] In this embodiment, the electrical box 90 is arranged above the heat exchanger 70, rationally utilizing the internal space of the indoor unit 100, effectively saving the space of the indoor unit 100, thereby reducing the volume of the indoor unit 100 and further reducing the production cost of the indoor unit 100.

[0055] In some preferred embodiments of the present invention, Figures 1 to 3As shown, the indoor unit 100 includes a water tray 20 and a water pump 30. The outlet 210 of the water tray 20 and the water inlet 310 of the water pump 30 are connected by a connecting hose 40. The outlet 210 of the water tray 20 is located at the rear of the indoor unit 100, while the water inlet 310 and water outlet 320 of the water pump 30 are located toward the rear. The outlet 210 of the water tray 20 is higher than the water inlet 310 of the water pump 30. The water pump 30 is mounted on the housing 10 via a mounting bracket 50. The mounting bracket 50 includes a first mounting portion 510, a second mounting portion 520, and a connecting portion 530. The first mounting portion 510 is horizontally disposed and is provided with a positioning hole 512 and a plurality of mounting slots 511. The water pump 30 is also provided with a plurality of mounting holes. Screws pass through the mounting slots 511 and the mounting holes to secure the water pump 30 to the mounting bracket 50. The connecting portion 530 connects the first mounting portion 510 and the second mounting portion 520. The connecting portion 530 is vertically disposed and perpendicular to the first mounting portion 510 and the second mounting portion 520. The connecting portion 530 includes a first connecting portion 531 and a second connecting portion 532. The length of the first connecting portion 531 is shorter than that of the second connecting portion 532. The second mounting portion 520 is vertically disposed. There are two second mounting portions 520, each connected to the first connecting portion 531 and the second connecting portion 532.

[0056] In this embodiment, when repairing or replacing the water pump 30, the mounting structure is first removed from the housing 10, the water pump 30 is then pulled out of the indoor unit 100, the connecting hose 40 is removed from the water pump 30, and the water pump 30 is removed from the mounting bracket 50 before repairing or replacing the water pump 30. Because the pipe between the water pump 30 and the water receiving pan 20 is a hose, the water pump 30 can be pulled to a convenient location for repair or replacement, thereby facilitating repair or replacement of the water pump 30 and improving the efficiency of repair or replacement of the water pump 30.

[0057] Furthermore, the height of the outlet 210 of the water receiving tray 20 is higher than the height of the water inlet 310 of the water pump 30. Due to the height difference between the outlet 210 and the water inlet 310, the condensed water flows downward under the action of gravity, which is conducive to the condensed water in the water receiving tray 20 to flow toward the water pump 30 during drainage, facilitating the drainage of the water receiving tray 20 and improving the drainage efficiency of the water pump 30.

[0058] Furthermore, the water outlet 320 and water inlet 310 of the water pump 30 are positioned toward the outlet 210 of the water tray 20 when the water pump 30 and the water tray 20 are connected. This prevents the connecting hose 40 from being bent in half, ensuring a smooth and uniform flow of condensed water, maintaining water pressure and facilitating the discharge of condensed water. Furthermore, the condensed water flows along the wall of the connecting hose 40, minimizing the impact of the condensed water on the connecting hose 40, preventing damage to the water pump 30 and the connecting hose 40 and increasing the service life of the water pump 30.

[0059] Furthermore, the water pump 30 is secured to the housing 10 via a mounting bracket 50. When attached to the housing 10, the mounting bracket 50 occupies minimal space, conforming to the shape of the housing 10 and avoiding a portion of the housing 10, facilitating securement of the water pump 30 to the housing 10. Furthermore, the screw connection provides a stable and reliable connection, preventing significant shaking of the water pump 30 during operation.

[0060] An embodiment of the present invention further provides an air conditioner, comprising the indoor unit 100 in any one of the above embodiments.

[0061] In some embodiments of the present invention, the air conditioner is a built-in air conditioner, which includes an embedded cabinet and an indoor unit 100 , and the indoor unit 100 is installed in the embedded cabinet.

[0062] In other embodiments of the present invention, the air conditioner may also be a wall-mounted air conditioner or a vertical air conditioner.

[0063] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
