[0036] Please see Figures 1-3 The air conditioner indoor unit 100 of the present application includes at least one housing 10 and a handle 20. The housing 10 includes an upper end 11, a lower end 12 and a middle part 13. The middle part 13 is located between the upper end 11 and the lower end 12. The thickness of the upper end 11 is greater than the thickness of the middle part 13. The handle 20 is installed on the upper end 11.

[0037] In the aforementioned air conditioner indoor unit 100, a handle 20 is provided at the upper end 11 of the air conditioner indoor unit 100, so that the center of gravity of the air conditioner indoor unit 100 is below the handle 20. The handle 20 makes the air conditioner indoor unit 100 easier to move and prevents it from shaking during the movement, thus improving the moving efficiency of the air conditioner indoor unit 100. In addition, the thickness of the upper end 11 of the housing 10 is greater than the thickness of the middle part 13, making the upper end 11 of the housing 10 stronger and the handle 20 more stable during use.

[0038] Specifically, the housing 10 can be a cubic structure, and it can accommodate other components of the indoor air conditioning unit 100. The housing 10 can have an airflow channel, through which airflow can flow into the room. The upper end 11 of the housing 10 refers to the end of the housing 10 located on its upper side under normal use; the upper end 11 is located at the upper edge of the housing 10. Similarly, the lower end 12 of the housing 10 is located at the lower edge of the housing 10.

[0039] The upper end 11 can be a single-layer board structure or a multi-layer board structure. When the upper end 11 is a single-layer board structure, the upper end 11 can be made thicker by locally thickening the single-layer board.

[0040] The handle 20 can be detachably mounted on the upper end 11 of the housing 10, or it can be non-detachably connected to the upper end 11 of the housing 10. Understandably, the handle 20 is a component for gripping. During the handling of the indoor air conditioner unit 100, the operator can grip the handle 20 to move the indoor air conditioner unit 100 to its destination. The handle 20 can have a semi-circular structure, a T-shaped structure, a long strip structure, etc.

[0041] Please see Figures 4-5 In some embodiments, the housing 10 includes a top plate 14 and a side plate 15 connected to the top plate 14, with a handle 20 mounted on the edge of the side plate 15 near the top plate 14. Thus, the handle 20 is mounted on the side plate 15 in a position that prevents it from interfering with other components of the indoor unit 100 and hindering the handling and installation of the indoor unit 100.

[0042] Specifically, the top plate 14 of the housing 10 is the panel facing upwards when the indoor unit 100 of the air conditioner is in normal use. The side plate 15 is located on one side of the housing 10. The housing 10 may also have front and rear plates, which are panels arranged along the airflow direction of the housing 10. Generally, the one downstream in the airflow direction is the front plate, and the one upstream in the airflow direction is the rear plate.

[0043] It should be noted that the handle 20 is mounted on the edge of the side panel 15, meaning that the side panel 15 can provide a mounting base structure for the handle 20. For example, the handle 20 can contact the side panel 15, or it can be mounted on the side panel 15 through an intermediate medium.

[0044] like Figure 4 As shown, in some embodiments, there is at least one side panel 15, and each side panel 15 is equipped with a handle 20. Since the indoor unit 100 of the air conditioner is relatively heavy, at least one side panel 15 is equipped with a handle 20, which makes it convenient for multiple operators to move the indoor unit 100 of the air conditioner.

[0045] Specifically, each side panel 15 may be equipped with one handle 20 or multiple handles 20. The number of handles 20 on each side panel 15 may be equal or unequal. When the total number of handles 20 on at least one side panel 15 is greater than two, the multiple handles 20 can be arranged around the center of gravity of the air conditioner indoor unit 100, making the air conditioner indoor unit 100 more stable during transportation.

[0046] Please see Figure 5 and Figure 6 In some embodiments, the top plate 14 includes a flat plate portion 141 and a bent portion 142 connected to the flat plate portion 141. The bent portion 142 is stacked with the side plate 15. The handle 20 is installed at the position corresponding to the side plate 15 and the bent portion 142. The upper end portion 11 includes the bent portion 142.

[0047] Thus, the bent portion 142 and the side plate 15 are stacked, which makes the upper end portion 11 thicker, thereby increasing the strength of the upper end portion 11 and improving the stability of the handle 20 during use.

[0048] Specifically, the flat plate portion 141 is located on the top side of the housing 10, and the bent portion 142 is bent relative to the flat plate portion 141. The bent portion 142 and the flat plate portion 141 can be arranged perpendicularly. The overall area of ​​the bent portion 142 is smaller than the overall area of ​​the flat plate portion 141. The flat plate portion 141 and the bent portion 142 can be made of the same sheet material and formed by a bending process.

[0049] Please see Figure 5 and Figure 6 In some embodiments, the bent portion 142 is located on the outer side of the side plate 15, and the end of the side plate 15 abuts against the flat plate portion 141. In this way, the side plate 15 can restrict the position of the top plate 14 and provide support for the top plate 14, making the connection between the top plate 14 and the side plate 15 more stable and improving the structural strength of the entire housing 10. In the above embodiments, the outer side of the side plate 15 refers to the side of the side plate 15 that is away from the internal center of the housing 10.

[0050] Please see Figure 6 In some embodiments, the handle 20 includes a grip portion 21, a connecting portion 22 and a mounting portion 23. The connecting portion 22 connects the grip portion 21 and the mounting portion 23. The mounting portion 23 fits against the bending portion 142. The handle 20 is disposed at the upper end 11 by a first fastener 30 passing through the mounting portion 23, the bending portion 142 and the side plate 15 in sequence.

[0051] In this way, the mounting part 23, the bending part 142 and the side plate 15 can overlap, and the position where the handle 20 is installed has at least two layers of plates, which increases the strength and improves the stability of the handle 20 installation.

[0052] Specifically, the grip 21, connecting part 22, and mounting part 23 can all be sheet-like structures, and the grip 21 and mounting part 23 can be arranged in parallel. The grip 21, connecting part 22, and mounting part 23 can be formed by stamping from the same sheet metal, or in other words, the grip 21, connecting part 22, and mounting part 23 can be an integrally formed structure. Since the bent part 142 is located on the outside of the side plate 15, after the mounting part 23 fits against the bent part 142, the contact area between the handle 20 and the housing 10 is increased, which can further improve the stability of the handle 20.

[0053] The first fastener 30 can be a screw, rivet, etc. Understandably, when the first fastener 30 is a screw, the handle 20 can be detachably connected to the housing 10.

[0054] Please refer to it again. Figure 2 and Figure 3 In some embodiments, the side panel 15 is provided with an inspection window 151, and the housing 10 includes an inspection plate 16 covering the inspection window 151. A portion of the inspection plate 16 is stacked with the bending portion 142, and the handle 20 is connected to the inspection plate 16.

[0055] Thus, the bent portion 142 of the top plate 14, the side plate 15, and the inspection plate 16 are stacked to form a three-layer plate structure. The upper end 11 of the box body 10 includes this three-layer plate structure, and the handle 20 is installed on the three-layer plate structure. That is to say, the inspection plate 16 can further increase the thickness of the upper end 11 of the box body 10, thereby improving the reliability of the handle 20 during use.

[0056] Specifically, the inspection window 151 extends through the side panel 15, allowing observation of the internal structure of the housing 10. For example, if a sensor is installed inside the housing 10, maintenance can be performed through the inspection window 151. The inspection plate 16 covers the inspection window 151, which reduces the entry of foreign objects into the housing 10 and improves the operational stability of the indoor air conditioning unit 100.

[0057] Please see Figure 3In some embodiments, a handle 20 is sequentially inserted through the handle 20, the access plate 16, the side plate 15, and the bend 142 at the upper end 11 via a first fastener 30. The handle 20 is fixedly connected to the access plate 16 via a second fastener 40. In this way, the access plate 16 can be held by the handle 20 during disassembly, making the access plate 16 easier to disassemble.

[0058] Specifically, the first fastener 30 can be, for example, a screw, allowing the access plate 16 to be removed from the side plate 15 when the first fastener 30 is removed. The second fastener 40 can be a screw or a rivet, securing the handle 20 to the access plate 16. During the removal of the access plate 16, the handle 20 remains fixed to the access plate 16, which not only facilitates the removal of the access plate 16 but also reduces the risk of the handle 20 being lost if it becomes detached from the access plate 16.

[0059] Of course, in other embodiments, the handle 20 can be fixedly connected to the inspection plate 16 by welding or other means.

[0060] Please see Figure 4 and Figure 7 , Figure 7 The illustrated indoor air conditioner unit 100 omits the handle 20. In some embodiments, there are two housings 10, which are detachably connected and communicate with each other. The indoor air conditioner unit 100 also includes a fan 50 and a heat exchanger 60. The fan 50 is disposed in one housing 10, and the heat exchanger 60 is disposed in the other housing 10. Each housing 10 is provided with a handle 20.

[0061] In this way, the indoor unit 100 of the air conditioner is divided into two parts, which makes it easier to move the indoor unit 100. Each box 10 is equipped with a handle 20, so that each box 10 can be moved through the handle 20, thereby facilitating the transportation and installation of the indoor unit 100 of the air conditioner.

[0062] Specifically, the two housings 10 can be fixed together by screws or other means. The structures of the two housings 10 can be different. For example, the housing 10 that houses the heat exchanger 60 may be equipped with a maintenance panel 16, while the housing 10 that houses the fan 50 may not have a maintenance window 151 on the side panel 15.

[0063] The fan 50 can be a centrifugal fan or an axial fan. The heat exchanger 60 can be arranged at an angle. This angled arrangement increases or decreases the height space occupied by the heat exchanger 60 after installation, resulting in a lower overall height of the indoor unit 100. This facilitates miniaturization of the indoor unit 100, thereby reducing its weight and simplifying installation and handling. The angled arrangement of the heat exchanger 60 refers to the overall surface of its inlet and outlet sides being inclined relative to the horizontal plane; in other words, the overall surface of the inlet and outlet sides of the heat exchanger 60 is inclined relative to the horizontal plane.

[0064] Please see Figure 8 The air conditioning system 1000 of this application includes an indoor unit 100 and an outdoor unit 200 as described in any of the above embodiments. The outdoor unit 200 is connected to the indoor unit 100 via pipes. Specifically, the outdoor unit 200 may include components such as a compressor. During operation, the compressor performs work on the refrigerant, allowing the refrigerant to exchange heat with the heat exchanger 60, thereby regulating the indoor temperature.

[0065] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
