[0017] According to some embodiments of the present invention, the limiting protrusion is provided with a guide arc surface, which guides and cooperates with the limiting groove so as to guide and cooperate with the limiting groove when the limiting protrusion enters and exits the limiting groove.

[0018] The above technical solution has the following advantages or beneficial effects: when the second end of the support rotates into the receiving groove, the guide arc surface can cooperate with the guide groove for limiting, so that the limiting protrusion can quickly enter the limiting groove for limiting cooperation with the limiting groove.

[0030] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0031] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0032] The following is based on Figures 1-11 This invention describes an embodiment of an air conditioner indoor unit 100.

[0033] According to an embodiment of the present invention, the indoor unit 100 of the air conditioner includes a housing 10, on which an air inlet 14 and an air outlet 11 are provided. Indoor air enters the indoor unit 100 of the air conditioner through the air inlet 14, and the indoor unit 100 of the air conditioner can blow air of a suitable temperature into the room through the air outlet 11 to adjust the indoor temperature to a preset temperature.

[0034] The indoor unit 100 of the air conditioner according to an embodiment of the present invention further includes a refrigerant circulation loop, an indoor fan, an outdoor fan, a power consumption sensor, and a controller.

[0035] In an embodiment of this utility model, the refrigerant circulation loop of the air conditioner consists of a compressor, a condenser, an expansion valve, and an evaporator. The refrigerant circulates between the compressor, condenser, expansion valve, and evaporator, thereby forming a refrigerant circulation loop.

[0036] The compressor compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant. This heat can be exchanged with indoor air to heat the indoor air, or with outdoor air to cool the indoor air. Furthermore, the compressor provides the power for the refrigerant's circulation.

[0037] One of the condensers and evaporator is the outdoor heat exchanger, and the other is the indoor heat exchanger. When the refrigerant enters the outdoor heat exchanger, it exchanges heat with the outdoor air. When the refrigerant enters the indoor heat exchanger, it exchanges heat with the indoor air.

[0038] When the air conditioner is in cooling mode, heat is transferred from the refrigerant to the outdoor air in the outdoor heat exchanger, and heat is transferred from the indoor air to the refrigerant in the indoor heat exchanger. This allows the refrigerant to dissipate indoor heat to the outdoor environment, thereby lowering the indoor temperature.

[0039] When the air conditioner is in heating mode, heat is transferred from the outdoor air to the refrigerant in the outdoor heat exchanger, and heat is transferred from the refrigerant to the indoor air in the indoor heat exchanger. This allows the refrigerant to absorb heat from the outdoor environment and transfer that heat to the indoor environment, thereby raising the indoor temperature.

[0040] An expansion valve can change the pressure of the refrigerant in the refrigerant circulation loop. By throttling and reducing pressure, the expansion valve converts the medium-temperature, high-pressure liquid refrigerant into low-temperature, low-pressure wet vapor, which then absorbs heat in the evaporator to achieve a cooling effect.

[0041] Furthermore, the expansion valve can automatically adjust the flow rate based on the superheat of the gaseous refrigerant at the evaporator outlet, maintaining a stable indoor temperature and meeting the requirements of refrigerant circulation. More importantly, the expansion valve can prevent liquid refrigerant from entering the compressor, avoiding liquid hammer and protecting the compressor from damage.

[0042] The fan assembly is used to drive indoor air through the air inlet 14 into the indoor unit 100 of the air conditioner by rotation, and then through the indoor heat exchanger to exchange heat between the refrigerant and the indoor air. Under the action of the fan assembly, the flow of indoor air to the indoor heat exchanger can be accelerated, thereby accelerating the heat exchange between the indoor air and the refrigerant.

[0043] The outdoor fan is used to drive outdoor air through the outdoor heat exchanger, so that the refrigerant and the outdoor air can exchange heat. Under the action of the outdoor fan, the flow of outdoor air to the outdoor heat exchanger can be accelerated, which can accelerate the heat exchange between the outdoor air and the refrigerant. Finally, the heat-exchanged air can be blown into the room through the air outlet 11.

[0044] A refrigerant pipe connects the outdoor heat exchanger and the compressor. The refrigerant pipe is used to transfer the refrigerant between the compressor and the outdoor heat exchanger, so as to realize the transfer of heat between the compressor and the outdoor heat exchanger.

[0045] Furthermore, the indoor unit 100 of the air conditioner also includes an electrical control box, which contains a control chip to realize the control function of the indoor unit 100 of the air conditioner.

[0046] Furthermore, the indoor unit 100 of the air conditioner also includes a panel 20, and the air outlet 11 is located on the front side of the housing 10. The panel 20 is elliptical and can be mounted on the front side of the housing 10 and selectively open and close the air outlet 11.

[0047] Specifically, the panel 20 is located on the front side of the casing 10 and on the front side of the air outlet 11. This allows the panel 20 to protect other structural components inside the indoor unit 100 of the air conditioner and prevent the heat exchange airflow of the indoor unit 100 from shifting, thereby ensuring stable airflow inside the indoor unit 100 to achieve stable heat exchange and air outlet.

[0048] Furthermore, the panel 20 is located on the front side of the housing 10 and can be selectively raised and lowered. This allows the panel 20 to selectively open the air outlet 11 on the front side of the housing 10 so that the indoor unit 100 of the air conditioner can blow air into the room. When the indoor unit 100 of the air conditioner is turned off and not in use, the panel 20 can be lowered to prevent dust or pests from entering the indoor unit 100 of the air conditioner through the air outlet 11.

[0049] Furthermore, the upper end of panel 20 is rotatably connected to housing 10. Panel 20 can be selectively rotated forward and upward. This arrangement allows the lower end of panel 20 to rotate relative to the upper end of panel 20. Thus, when panel 20 is opened from the front of housing 10, panel 20 can rotate forward and upward, causing the lower end of panel 20 to move away from the front of housing 10. This exposes the filter inside the indoor unit 100 of the air conditioner, facilitating cleaning of the filter and removing surface dust. This improves the ventilation rate of the filter, thereby enhancing its filtration effect and increasing the airflow rate within the duct, ultimately improving the air volume and quality of the indoor unit 100 of the air conditioner.

[0050] Furthermore, a support member 21 is provided on the panel 20, so that the support member 21 can move forward and upward relative to the end of the panel 20 that is connected to the front side of the housing 10.

[0051] Furthermore, the first end 211 of the support member 21 is rotatably connected to the panel 20, so that the second end 212 of the support member 21 can rotate relative to the first end 211, thereby changing the position of the second end 212 of the support member 21.

[0052] Furthermore, the second end 212 of the support member 21 is provided with a first abutting part 2121, and the front side of the housing 10 is provided with a second abutting part 12. One of the first abutting part 2121 and the second abutting part 12 is an abutting groove, and the other is an abutting block. When the panel 20 is rotated forward and upward to a preset position, the abutting block extends into the abutting groove and abuts against the abutting groove.

[0053] Specifically, the first abutting portion 2121 of the second end 212 of the support member 21 can rotate relative to the first end 211 to change the position of the first abutting portion 2121.

[0054] Furthermore, the front side of the housing 10 is the side close to the panel 20. A second abutment portion 12 is provided on the front side of the housing 10. In this way, the position of the first abutment portion 2121 can be changed by rotating the second end 212 of the support member 21, so that the first abutment portion 2121 and the second abutment portion 12 can come into contact and engage with each other.

[0055] Furthermore, when the first abutting part 2121 and the second abutting part 12 are engaged, the first end 211 of the support member 21 remains connected to the panel 20. In this way, the support member 21 can support the panel 20 to remain in the current position during the rotation process. This position is the preset position to which the panel 20 rotates forward and upward.

[0056] Furthermore, the engagement of the first abutting part 2121 and the second abutting part 12 is actually the engagement of the abutting block and the abutting groove. The contact area of ​​the abutting block and the abutting groove is large, and they are mutually restrained reliably. This arrangement can ensure the abutting reliability of the first abutting part 2121 and the second abutting part 12, and thus ensure the structural stability of the panel 20 when it is held in the preset position. In this way, the safety of personnel can be guaranteed when cleaning the filter screen.

[0057] Combination Figure 1 , Figure 6 and Figure 7As shown, a filter support rod 13 extending vertically is provided on the front side of the housing 10. The filter support rod 13 can provide support for the filter inside the indoor unit 100 of the air conditioner and can position the filter inside the housing 10 near the front. This not only allows the filter to be arranged on the air duct of the indoor unit 100 to filter the air entering the indoor unit 100, but also allows the filter to be positioned near the panel 20. In this way, when the panel 20 is rotated forward and upward, the filter can be directly exposed and there will be no obstructions in front of the filter, which facilitates cleaning of the filter.

[0058] Furthermore, the filter support rod 13 is provided with an abutment groove. Specifically, the filter support rod 13 has a certain structural strength, and the abutment groove is provided on the filter support rod 13. This ensures the structural strength of the abutment groove and allows the abutment groove to provide a stable and reliable abutment force to the abutment block, so as to ensure that the support member 21 can provide stable and reliable support to the panel 20 when it is in the preset position.

[0059] Furthermore, the second end 212 of the support member 21 is formed with an abutment block, which abuts against the filter screen support rod 13. Specifically, the support member 21 has a certain structural strength, which allows the abutment block to have a certain structural rigidity, so that the abutment block can reliably abut against the abutment groove. Moreover, the abutment block is located at the second end 212 of the support member 21. Thus, although the abutment block moves away from the filter screen support rod 13 along with the support member 21 when the panel 20 rotates forward and upward, the second end 212 of the support member 21 can rotate around the first end 211. This allows the abutment block to move towards the filter screen support rod 13, thereby allowing the second end 212 of the support member 21 to contact the filter screen support rod 13, so that the abutment block abuts against the abutment groove.

[0060] Combination Figure 1 , Figure 6 and Figure 7 As shown, there are multiple filter support rods 13. By setting multiple filter support rods 13 on the housing 10, multiple support positions can be provided for the filter. This not only allows for the design of the filter installation range in the indoor unit 100 of the air conditioner, but also enhances the reliability of the filter installation on the housing 10.

[0061] Furthermore, multiple filter support rods 13 are spaced apart in the left and right directions of the housing 10, so that the multiple filter support rods 13 can provide uniform support force to the filter as a whole, so as to ensure the reliability of the filter installation in the indoor unit 100 of the air conditioner.

[0062] Furthermore, one of the multiple filter support rods 13 is located in the middle of the left-right direction, and the filter support rod 13 located in the middle of the left-right direction of the housing 10 is provided with an abutment groove.

[0063] Specifically, in this embodiment of the invention, among the multiple filter support rods 13 spaced apart in the left-right direction, the filter groove is set on the filter support rod 13 at the middle position in the left-right direction. In this way, the support member 21 abuts against the filter support rod 13 at the middle position in the left-right direction, which can make the support member 21 support the panel 20 more evenly in the left-right direction. With this arrangement, when the panel 20 is rotated forward and upward to the preset position, the entire panel 20 can be supported by one support member 21, which can ensure the structural stability of the panel 20.

[0064] Combination Figure 1 , Figure 6 and Figure 7 As shown, abutment pieces 131 are provided on both sides of the filter support rod 13. The abutment pieces 131 form abutment grooves. With this arrangement, the contact area between the abutment piece 131 and the abutment groove and abutment block formed by the filter support rod 13 is larger, which can improve the reliability of the abutment fit between the abutment groove and the abutment block, and thus help improve the structural stability of the panel 20 in the preset position.

[0065] Furthermore, the second end 212 of the support member 21 is provided with a relief groove, which avoids the filter support rod 13, and the second end 212 of the support member 21 forms an abutment block corresponding to the positions on both sides of the relief groove.

[0066] Specifically, the two abutting blocks abut against the abutting groove, and the clearance groove between the two abutting blocks abuts against the filter support rod 13. In this way, the abutting blocks and the abutting groove limit each other in the front-back direction and the up-down direction, and the clearance groove and the filter support rod 13 limit each other in the left-right direction. This arrangement can prevent the second end 212 of the support member 21 from moving in the front-back direction, the up-down direction and the left-right direction, so that the support member 21 can provide stable and reliable support for the panel 20.

[0067] Combination Figure 1 As shown, a receiving groove 22 is provided on the side of the panel 20 facing the housing 10. The first end 211 of the support member 21 is rotatably connected to the side wall of the receiving groove 22, and the second end 212 of the support member 21 is selectively limited to the side wall of the receiving groove 22.

[0068] Specifically, the receiving groove 22 on the panel 20 is recessed forward, so that the support member 21 can be stored when it is not in use, so that the side surface of the panel 20 facing the housing 10 is flat. This not only prevents the support member 21 from interfering with other structural components inside the air conditioner indoor unit 100, but also helps to improve the structural compactness of the panel 20 and improve the space utilization of the air conditioner indoor unit 100.

[0069] Combination Figure 6 As shown, the second end 212 of the support member 21 is provided with a limiting protrusion 2122, and the side wall of the receiving groove 22 is provided with a limiting groove 221. The limiting protrusion 2122 and the limiting groove 221 are in a limiting fit.

[0070] Specifically, when the support member 21 is housed in the receiving groove 22, it is necessary to ensure that the support member 21 remains stable and immobile within the receiving groove 22 to prevent the support member 21 from rotating and colliding with other structural components or people.

[0071] In an embodiment of this utility model, a limiting groove 221 is provided on the lower side wall of the receiving groove 22, and a limiting protrusion 2122 is provided at the position of the support member 21 adjacent to the second end 212, that is, adjacent to the limiting groove 221. The limiting protrusion 2122 can cooperate with the limiting groove 221 for limiting. In this way, when the support member 21 is stored in the receiving groove 22, the limiting protrusion 2122 and the limiting groove 221 can ensure that the position of the support member 21 in the receiving groove 22 remains unchanged. This can ensure the structural stability of the support member 21 in the receiving groove 22 and prevent the support member 21 from shaking when the panel 20 is opened.

[0072] Combination Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the limiting protrusion 2122 is provided with a guide arc surface 21221, which guides and engages with the limiting groove 221 so that the limiting protrusion 2122 engages with the limiting groove 221 when it enters or exits the limiting groove 221.

[0073] Specifically, the limiting protrusion 2122 protrudes from the side of the support member 21, and a guide arc surface 21221 is provided on the limiting protrusion 2122. When the second end 212 of the support member 21 rotates into the receiving groove 22, the guide arc surface 21221 can cooperate with the guide groove 223 for limiting. This allows the limiting protrusion 2122 to quickly enter the limiting groove 221 for limiting cooperation with the limiting groove 221.

[0074] Combination Figure 1 and Figure 2As shown, the side wall of the receiving groove 22 is provided with a rotating hole 222, and the support member 21 is provided with a rotating shaft 213. The rotating shaft 213 extends into the rotating hole 222 and is rotatable relative to the rotating hole 222. Specifically, the rotating shaft 213 and the rotating hole 222 cooperate to make the first end 211 of the support member 21 and the rotating hole 222 of the side wall of the receiving groove 22 coaxially arranged. This allows the first end 211 of the support member 21 to be connected to the panel 20, and the second end 212 of the rotating shaft 213 can rotate around the first end 211.

[0075] Furthermore, guide grooves 223 are provided on both sides of the receiving groove 22, and the guide grooves 223 correspond to the rotating hole 222 to guide the rotating shaft 213 when it enters the receiving groove 22.

[0076] Specifically, the guide groove 223 is located on the side of the receiving groove 22, and the bottom of the guide groove 223 gradually slopes toward the rotating hole 222. In this way, when installing the first end 211 of the support member 21 and the panel 20, the rotating shaft 213 can slide into the rotating hole 222 through the guide groove 223, thereby reducing the installation difficulty of the rotating shaft 213 and the rotating hole 222, and thus improving the installation convenience of the support member 21 and the panel 20, which is conducive to improving the assembly convenience of the air conditioner indoor unit 100.

[0077] Combination Figure 4 As shown, the side wall of the receiving groove 22 is provided with a limiting rib 224, which is engaged with the support member 21 for limiting. The limiting rib 224 and the limiting groove 221 are spaced apart from each other. Specifically, the limiting rib 224 protrudes from the surface of the side wall of the receiving groove 22. When the support member 21 is pressed into the receiving groove 22, the limiting rib 224 can clamp the support member 21 to fix the limiting rib 224 in the receiving groove 22.

[0078] Furthermore, the limiting rib 224 and the limiting groove 221 are arranged at intervals. This not only allows the limiting rib 224 to avoid the limiting groove 221, but also increases the limiting position of the support member 21 in the length direction in the receiving groove 22, thereby improving the stability of the support member 21 in the length direction in the receiving groove 22.

[0079] Combination Figure 1 , Figure 3 and Figure 4 As shown, the limiting rib 224 is set near the first end 211 of the support member 21. This setting allows the limiting rib 224 to be set away from the limiting groove 221. In this way, the limiting rib 224 and the limiting groove 221 can limit the support member 21 along the length direction of the support member 21, thereby improving the reliability of the support member 21 in the receiving groove 22.
