[0032] 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 comprising a housing 10, a fan 20, and an electrical box 40. The fan 20 is horizontally disposed within the housing 10, with one end of the fan 20 connected to a motor 30. The electrical box 40 is disposed above the motor 30 and includes a box wall 410. The outer surface of the box wall 410 is in close contact with the inner surface of the top end of the housing 10. A heat exchanger is also disposed above the fan 20. An air inlet and an air outlet 80 are defined on the front side of the housing 10, with the air inlet disposed above the air outlet 80.

[0033] In this embodiment, the fan 20 is positioned horizontally, and the motor 30 is connected to one end of the fan 20 to drive the fan 20. The electrical box 40 is positioned in the free space above the motor 30. When the air conditioner is operating, air enters the indoor unit 100 through the air inlet, exchanges heat in the heat exchanger, and is blown into the room through the air outlet 80 by the fan 20. The electrical box 40 does not occupy the top space of the indoor unit 100, effectively utilizing the internal space of the indoor unit 100 and preventing the electrical box 40 from interfering with air flow. This ensures more air flow into the indoor unit 100, thereby improving the performance of the indoor unit 100. The electrical box 40 does not occupy the side space of the indoor unit 100, effectively saving space within the indoor unit 100. While maintaining the size of the indoor unit 100, it can increase the usable space for the fan 20 and heat exchanger, thereby increasing the length of the fan 20 and heat exchanger, further improving the performance of the indoor unit 100.

[0034] Furthermore, the electrical box 40 is used to install and protect the computer board. The electrical box 40 is set in the upper space inside the indoor unit 100 to prevent condensed water in the indoor unit 100 from entering the electrical box 40, preventing the computer board from malfunctioning due to water exposure, and can protect the computer board.

[0035] In some embodiments of the present invention, the electrical appliance box 40 further includes a box bottom, and the box wall 410 and the box bottom define a receiving cavity with an opening, and the opening is arranged toward the front side.

[0036] In this embodiment, the electrical box 40 is composed of a box wall 410 and a box bottom. The electrical box 40 has an opening, which faces the front side of the indoor unit 100. When installing the computer board, the computer board can be placed into the electrical box 40 through the front opening, which is relatively convenient for installation.

[0037] In some embodiments of the present invention, Figure 1 As shown, the electrical box 40 further includes a box cover 420 , which is disposed at the opening to close the opening.

[0038] In this embodiment, the electrical box 40 further includes a cover 420 that covers the opening. After the computer board is installed in the electrical box 40, the cover 420 seals the opening, preventing dust and water from entering the electrical box 40, thus preventing dust accumulation or water damage to the computer board and further protecting the computer board.

[0039] In some embodiments of the present invention, the accommodating cavity includes at least one sub-accommodating cavity for installing at least one computer board.

[0040] In this embodiment, the housing box includes at least one sub-housing chamber, each of which can accommodate a computer board. At least one computer board can be installed in each chamber, and an appropriate number of computer boards can be installed based on the air conditioner's functionality to improve the performance of the indoor unit 100 and, in turn, enhance the user experience. For example, the electrical box 40 can accommodate one, two, or three computer boards.

[0041] In some embodiments of the present invention, Figures 1 to 3 As shown, the electrical box 40 extends in the front-to-back direction and has an L-shaped cross-section. The height of the side of the electrical box 40 closer to the fan 20 is less than the height of the side farther from the fan 20. Multiple heat exchange elbows are provided on the side of the heat exchanger closer to the fan 20, i.e., the heat exchange elbows are located above the fan 20.

[0042] In this embodiment, the electrical box 40 has an L-shaped cross-section. The side of the electrical box 40 closest to the fan 20 is lower, avoiding the fan 20 and the heat exchange elbow, preventing the electrical box 40 from interfering with the normal operation of the fan 20 and the heat exchanger. The rational design of the electrical box 40's shape allows for optimal utilization of the internal space of the indoor unit 100, effectively saving space within the indoor unit 100. This allows for more space to be utilized for other components or reduces the size of the indoor unit 100, thereby improving the performance of the indoor unit 100 or reducing its production costs.

[0043] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the indoor unit 100 further includes an air pipe 50, a liquid pipe 60, and a connecting pipe 70. The air pipe 50 is used to transport refrigerant to the outdoor unit and includes a first air pipe section 510 and a second air pipe section. The liquid pipe 60 is used to transport refrigerant to the indoor unit 100 and includes a first liquid pipe section 610 and a second liquid pipe section. The connecting pipe 70 is wrapped around the outside of the second air pipe section and the second liquid pipe section.

[0044] In this embodiment, the air pipe 50 and the liquid pipe 60 connect the indoor unit 100 and the outdoor unit. During air conditioner operation, the refrigerant is converted to a liquid state in the outdoor unit and transported to the indoor unit 100 via the liquid pipe 60. After heat exchange with the air, the refrigerant is converted from liquid to gas and transported to the outdoor unit via the air pipe 50, completing the refrigerant circulation. The connecting pipe 70 encloses the second air pipe segment and the second liquid pipe segment, thus aligning the second air pipe segment and the second liquid pipe segment, reducing the space occupied by the second air pipe segment and the second liquid pipe segment, and effectively utilizing the internal space of the indoor unit 100. Furthermore, the connecting pipe 70 protects the second air pipe segment and the second liquid pipe segment, preventing damage.

[0045] In some embodiments of the present invention, Figure 4As shown, the connecting pipe 70 includes a first connecting pipe section 710, a second connecting pipe section 720, and a third connecting pipe section 730. The first connecting pipe section 710 is horizontally disposed above the fan 20 and extends in the front-to-back direction. The second connecting pipe section 720 is connected to the rear end of the first connecting pipe section 710 and is vertically disposed behind the fan 20. The third connecting pipe section 730 is connected to the lower end of the second connecting pipe section 720 and is horizontally disposed behind the fan 20 and extends in the left-to-right direction. The housing 10 is provided with a through hole to allow the third connecting pipe section 730 to pass through.

[0046] In this embodiment, the connecting pipe 70 includes a first connecting pipe 70, a second connecting pipe section 720, and a third connecting pipe section 730. The first connecting pipe section 710 is positioned above the fan 20, while the second connecting pipe section 720 and the third connecting pipe section 730 are positioned behind the fan 20. Specifically, the placement of the connecting pipe 70 above and behind the fan 20 minimizes the impact on the airflow into the indoor unit 100, ensuring more adequate airflow to the indoor unit 100 and thereby improving the performance of the indoor unit 100. Furthermore, the placement of the connecting pipe 70 rationally utilizes the internal space of the indoor unit 100, reducing the size of the indoor unit 100 or increasing the available space for the heat exchanger and fan 20, thereby reducing the production cost of the indoor unit 100 or improving the performance of the air conditioner.

[0047] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the housing 10 includes a support frame 110 , which is vertically disposed above the fan 20 to support the first connecting pipe section 710 .

[0048] In this embodiment, the housing 10 includes a support frame 110, which is used to support the first connecting pipe section 710. The flow of air, the flow of refrigerant in the air pipe 50, or the flow of refrigerant in the liquid pipe 60 can cause the first connecting pipe 70 to wobble. The support frame 110 securely supports the first connecting pipe section 710, improving the structural stability of the connecting pipe 70 and preventing damage to the air pipe 50 or liquid pipe 60 or other structures caused by shaking.

[0049] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the first connecting pipe section 710 passes through the support frame 110 .

[0050] In this embodiment, the first connecting pipe section 710 passes through the support frame 110. The support frame 110 supports and secures the first connecting pipe section 710, preventing it from swaying up and down or left and right. This improves the structural stability of the connecting pipe 70 and prevents damage to the gas pipe 50 or liquid pipe 60 caused by swaying, or other structures. Furthermore, the support and securing method for the first connecting pipe section 710 is simple and convenient, facilitating the manufacture of the indoor unit.

[0051] In other embodiments of the present invention, a fixing groove with an upward opening is provided on the support frame 110 , and the first connecting pipe section 710 is disposed in the fixing groove.

[0052] In this embodiment, the support frame 110 supports the first connecting pipe section 710 below it, preventing it from wobbling. The walls on both sides of the fixing groove prevent the first connecting pipe 710 from wobbling sideways, thereby improving the structural stability of the connecting pipe 70 and preventing damage to the air pipe 50 or liquid pipe 60 caused by wobbling or other structures. Furthermore, the support and fixing method for the first connecting pipe section 710 is simple and convenient, facilitating the manufacture of the indoor unit.

[0053] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the first air pipe section 510 is horizontally disposed above the fan 20 and extends in the front-to-back direction. The first liquid pipe section 610 is horizontally disposed above the fan 20 and is connected to the second liquid pipe section via an arcuate pipe 620. The inlet direction of the arcuate pipe 620 is the same as the outlet direction of the first air pipe section 510, so that the second liquid pipe section and the second air pipe section run in the same direction.

[0054] In this embodiment, the first air pipe section 510 and the first liquid pipe section 610 are located above the fan 20. The curved pipe 620 redirects the first liquid pipe section 610 so that the second liquid pipe section aligns with the second air pipe section. This facilitates the connection pipe 70 wrapping around the outside of the second air pipe section and the second liquid pipe section. This connection of the connection pipe 70 at the top of the indoor unit 100 minimizes the impact on the air flow to the indoor unit 100, ensuring a more adequate air flow to the indoor unit 100 and improving the performance of the indoor unit 100.

[0055] In some preferred embodiments of the present invention, Figures 1 to 4 As shown, the indoor unit 100 includes a housing 10, an electrical box 40, and a connecting pipe 70. The electrical box 40 is positioned above the motor 30, with the outer surface of the upper wall 410 of the electrical box 40 in close contact with the inner surface of the top end of the housing 10. The electrical box 40 extends in the front-to-back direction and has an L-shaped cross-section. The connecting pipe 70 wraps around the outside of the second air pipe segment and the second liquid pipe segment and is located in the space above and behind the fan 20.

[0056] In this embodiment, the electrical box 40 is disposed above the motor 30 and near the top of the housing 10. The electrical box 40 does not occupy the top space of the indoor unit 100, effectively utilizing the internal space of the indoor unit 100 and preventing the electrical box 40 from interfering with air flow into the indoor unit 100. This ensures a more adequate air intake for the indoor unit 100, thereby improving the performance of the indoor unit 100. The electrical box 40 does not occupy the side space of the indoor unit 100, effectively saving space within the indoor unit 100. While maintaining the same volume, this allows for more space for the fan 20 and heat exchanger, increasing the length of the fan 20 and heat exchanger, further improving the performance of the indoor unit 100.

[0057] Furthermore, the connection of the connecting pipe 70 at the top of the housing 10 has minimal impact on the air intake of the indoor unit 100, ensuring a more adequate air intake for the indoor unit 100 and thereby improving the performance of the indoor unit 100. Furthermore, the connection pipe 70 is positioned above and behind the fan 20, effectively utilizing the internal space of the indoor unit 100. This can reduce the size of the indoor unit 100 or increase the usable space for the heat exchanger and fan 20, thereby reducing the production cost of the indoor unit 100 or improving the performance of the air conditioner.

[0058] An embodiment of the present invention further provides an air conditioner, comprising the indoor unit 100 as in any one of the above embodiments.

[0059] In some embodiments of the present invention, the air conditioner is a built-in air conditioner, comprising an embedded cabinet and an indoor unit 100. The embedded cabinet is provided with a mounting hole for allowing the connecting pipe 70 to pass through.

[0060] In this embodiment, after the indoor unit 100 is secured to the built-in cabinet, the connecting pipe 70 extends directly from the mounting hole to the outside. The connecting pipe 70 does not occupy additional space within the built-in cabinet, allowing the indoor unit 100 to utilize a larger area. This, in turn, improves the performance of the indoor unit 100 by increasing the size of the fan 20 or heat exchanger within the indoor unit 100. Furthermore, the connecting pipe 70 is located at the top of the indoor unit 100, minimizing the impact on the air flow into the indoor unit 100 and preventing it from affecting the performance of the indoor unit 100.

[0061] In other embodiments of the present invention, the air conditioner may also be a wall-mounted air conditioner or a vertical air conditioner.

[0062] 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. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
