DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0030] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] This application relates to the technical field of air conditioner structures. Specifically, an air conditioner performs the refrigerant cycle through a compressor, a condenser, an expansion valve, and an evaporator. The refrigerant cycle includes a series of processes involving compression, condensation, expansion, and evaporation. The compressor compresses the refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser, which condenses the compressed refrigerant into a liquid phase and releases heat to the surrounding environment through the condensation process. The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. During the entire refrigerant cycle, the air conditioner can adjust the temperature and humidity of the indoor space.

[0032] The outdoor unit of the air conditioner includes a compressor and an outdoor heat exchanger, and the indoor unit of the air conditioner includes an indoor heat exchanger. The expansion valve can be provided in the indoor unit or the outdoor unit of the air conditioner. One of the indoor heat exchanger and the outdoor heat exchanger serves as a condenser, and the other serves as an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in the heating mode, and when the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in the cooling mode.

[0033] A preferred embodiment of the handle of the present invention is used for the indoor unit of an air conditioner. The indoor unit of the air conditioner includes a base 3 and an air duct chamber 2 detachably connected to the base 3. The handle is installed on the air duct chamber 2. The air duct chamber 2 includes an air duct chamber side wall. As Figures 1-6 shown, the handle includes a handle body 1. A rotating shaft 11 is provided at the first end of the handle body 1. The rotating shaft 11 is detachably inserted and rotated from the inside to the outside on the air duct chamber side wall. A locking portion 14 for detachably connecting to the base 3 is provided on the handle body 11. Rotating the rotating shaft 11 can cause the locking portion 14 to be locked to the base 3, so as to achieve the purpose of fixing the air duct chamber 2 and the base 3 by using the handle. At the same time, when it is necessary to disassemble the air duct chamber 2, operate the handle body to rotate the rotating shaft 11 to drive the locking portion 14 to rotate, and then move the rotating shaft 11 out of the air duct chamber side wall to remove the handle. At this time, the fixing effect between the air duct chamber 2 and the base 3 can be released. The installation and disassembly processes are simple and convenient, facilitating the disassembly and assembly of the air duct chamber 2 and the base 3, and facilitating the cleaning of the air duct chamber 2.

[0034] Specifically, as Figure 2As shown, a rotating hole 21 is provided on the side wall of the air duct cavity 2, and the rotating shaft 11 is arranged in a direction perpendicular to the handle body 1, so that when the rotating shaft 11 is inserted on the side wall of the air duct cavity 2, the handle body 11 can extend to the outside of the air duct cavity 2, which is convenient for operating the handle body 11. A toggle portion 12 is provided at the second end of the handle body 11, and the rotating shaft 11, the handle body 11 and the toggle portion 12 of the present invention are integrally formed. A boss 13 is provided on the rotating shaft 11, and a groove 23 matching the boss 13 is provided in the rotating hole 21. The rotating shaft 11 can be directly inserted into the rotating hole 21. After the rotating shaft 11 is inserted into the rotating hole 21, the rotating shaft 11 is rotated so that the boss 13 stops on the air duct cavity 2 near the rotating hole 21.

[0035] Furthermore, the handle body 11 is provided with a stopper 15 protruding from the side of the handle body, and the stopper 15 is used to match with the stopper groove 22 on the side wall of the air duct cavity 2 to limit the rotation of the handle body. The base 3 is provided with a clamping groove 31, and when the boss 13 is clamped on the clamping groove 31 of the base 3, the stopper 15 matches with the stopper groove 22 reserved on the side wall of the air duct cavity 2 to prevent the handle from rotating, and can limit the position of the handle.

[0036] Specifically, the limit block 15 is provided with a plurality of limit inclined surfaces to facilitate the matching insertion of the limit block and the limit groove 22. The limit block 15 extends upward from the bottom surface connected to the handle body, and has four side surfaces, wherein the two opposite side surfaces are respectively a first guide inclined surface 151 and a second guide inclined surface 152, the first guide inclined surface 151 is inclined from the bottom surface of the limit block 15 to the center of the limit block 15, and the second guide inclined surface 152 is also inclined from the bottom surface of the limit block 15 to the center of the limit block 15. The other two side surfaces of the limit block 15 are located between the first guide inclined surface 151 and the second guide inclined surface 152 and are both inclined to the central part of the limit block 15, and one of the limit inclined surfaces is triangular, so that the top of the limit block 15 is triangular, and correspondingly, the groove wall of the limit groove 22 of the air duct cavity 2 is an inclined surface matching the side surface of the limit block 15. The side surface of the limiting block 15 is arranged as an inclined surface so as to facilitate the limiting block to be inserted into the limiting groove and to facilitate the limiting block 15 to be removed from the limiting groove 22 .

[0037] Among them, the width of the handle body 1 gradually increases from the first end to the second end of the handle body 1, so that the handle body 1 is arranged in a fan shape, which meets the strength and stiffness requirements of the handle body 1 on the one hand, reduces the volume and weight on the other hand, and has aesthetics; the toggle portion 12 is in the shape of a long strip, and the width of the toggle portion 12 is 1 / 4 to 1 / 3 of the width of the end of the handle body 1 to reduce the weight of the handle. The toggle portion 12 is integrally and smoothly connected to one side of the second end of the handle body 1 to increase the strength and stiffness of the toggle portion 12; the limit block 15 is arranged at the intersection of the handle body 1 and the toggle portion 12. The position of the limit portion 15 matches and corresponds to the position of the limit slot 22 on the air duct cavity 2, and can be set at other positions of the handle body 1 according to design requirements.

[0038] Furthermore, a plurality of mesh-shaped weight-reducing grooves 16 are provided on one side surface of the handle body 1 and the toggle portion 12 to reduce the weight of the handle.

[0039] Furthermore, a cylindrical connecting portion is integrally formed at the second end of the handle body 1, the rotating shaft 11 is integrally and vertically arranged at one side of the connecting portion, a circular groove 23 is arranged at the other side of the connecting portion, and the position of the connecting portion opposite to the boss 13 is flush with the outer surface of the rotating shaft 11. The above arrangement further reduces the weight of the rotating shaft 11 and the connecting portion 12 while ensuring the strength requirements, and at the same time improves the aesthetics of the handle.

[0040] After the rotating shaft 11 of the handle of the present invention is inserted into the air duct cavity 2, the rotating shaft 11 can be rotated to make the locking portion 14 locked on the base 3, so that the purpose of using the handle to fix the air duct cavity 2 and the base 3 can be achieved. When the air duct cavity 2 needs to be disassembled, the handle body 1 is operated to rotate the rotating shaft 11 to drive the locking portion 14 to rotate, and then the rotating shaft 11 is moved out from the inner side wall of the air duct cavity 2 to remove the handle. At this time, the fixing effect of the air duct cavity 2 and the base 3 can be released, and the installation and disassembly process is simple, which is convenient for the disassembly of the air duct cavity 2 and the base 3, and convenient for cleaning the air duct cavity 2.

[0041] An air conditioner indoor unit comprises a handle, the structure of the handle is the same as the structure in the above handle embodiment.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
