DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0030] See also Figure 1-Figure 5The present application provides a graphene defrost structure including an air energy heat pump component 100 and a defrost component 200 .

[0031] See also Figure 1 and 2 The air energy heat pump assembly 100 includes an air energy heat pump body 110 , a fixing plate 120 and a motor 140 . The fixing plate 120 is disposed in the air energy heat pump body 110 , and the motor 140 is installed on one side of the fixing plate 120 .

[0032] See also Figure 1 , 3 , 4 and 5, the defrost assembly 200 includes a graphene heating plate 210, a docking plate 220, a clamping rod 230 and an elastic member 250, the docking plate 220 is fixedly connected to the surface of the motor 140, the docking plate 220 is provided with a connecting cavity 221, the elastic member 250 is arranged in the connecting cavity 221, the clamping rod 230 is arranged at the end of the elastic member 250, the graphene heating plate 210 is sleeved on the surface of the motor 140, and the end of the clamping rod 230 is clamped to the graphene heating plate 210.

[0033] Among them, the elastic member 250 includes a spring 251 and a movable plate 252, two movable plates 252 are provided, and the two movable plates 252 are both slidably arranged in the connecting chamber 221, the spring 251 is arranged between the two movable plates 252, the spring 251 is located in the connecting chamber 221, and the clamping rod 230 is fixedly connected to the movable plate 252. By setting the spring 251 and the movable plate 252, utilizing the elastic effect of the spring 251, in the absence of external gas force, the spring 251 pushes the movable plate 252, and the movable plate 252 drives the clamping rod 230 to remain facing the connecting chamber 221, so that the clamping rod 230 remains clamped and connected to the graphene heating plate 210.

[0034] It should be noted that there are two graphene heating plates 210, the ends of the two graphene heating plates 210 are rotatably connected, and the two graphene heating plates 210 are both fitted and sleeved on the surface of the motor 140. By providing two mutually rotating graphene heating plates 210, they can be conveniently and symmetrically rotated and sleeved on the motor 140, and fit the surface of the motor 140 to ensure the heating and defrosting effect.

[0035] In a specific embodiment, the ends of the two graphene heating plates 210 are rotatably connected via a rotating shaft 260, and the two graphene heating plates 210 are symmetrical and do not extend to the surface of the motor 140. By setting the rotating shaft 260, the purpose of the two graphene heating plates 210 rotating relative to each other is achieved.

[0036] Specifically, a connecting block 211 is provided at the end of the graphene heating plate 210, and a through hole 212 is opened in the connecting block 211. The clamping rod 230 and the through hole 212 are adapted to each other. By setting the connecting block 211 and opening the through hole 212, the clamping connection purpose is achieved by inserting the clamping rod 230 into the through hole 212.

[0037] It should be noted that the connecting blocks 211 at the ends of the two graphene heating plates 210 are arranged alternately, and the connecting blocks 211 fit the docking plates 220. By setting the connecting blocks 211 to fit the docking plates 220, the graphene heating plates 210 can be prevented from sliding axially along the motor 140, thereby preventing them from loosening and falling off due to vibration.

[0038] In a specific implementation, a power connector 121 is provided on one side of the fixing plate 120, and the connector of the graphene heating plate 210 is plugged into the power connector 121. The power connector 121 is provided to electrically heat the graphene heating plate 210.

[0039] The utility model further provides an air energy heat pump including the above-mentioned graphene defrosting structure.

[0040] The graphene defrosting structure and the working principle of the air energy heat pump are as follows: when in use, the graphene heating plate 210 is started to heat up quickly while the motor 140 is started. The heating of the outer surface of the graphene heating plate 210 will melt the frost and remove it. The heating of the inner surface of the graphene heating plate 210 makes the motor 140 start at a suitable temperature. The motor 140 starts quickly and smoothly, avoiding the situation where a large amount of electricity is consumed by starting at a low temperature. Compared with the electricity consumed by the graphene heating plate 210, it is still saved. When disassembly and maintenance is required, the moving plate 252 is pulled, and the moving plate 252 drives the clamping rod 230 to move. The two moving plates 252 squeezes the spring 251, and the clamping rod 230 moves out of the through hole 212, so that the two graphene heating plates 210 can be rotated, and the graphene heating plates 210 are removed from the motor 140. During installation, the movable plate 252 is pulled in the same way, and the two graphene heating plates 210 are rotated and docked on the surface of the motor 140, and the movable plate 252 is loosened. The elastic action of the spring 251 is used to push the movable plate 252, and the movable plate 252 drives the clamping rod 230 to move and insert into the through hole 212 to realize the clamping connection, which is convenient for the disassembly, assembly and replacement of the graphene heating plates 210, and is conducive to the later disassembly, assembly and maintenance, thereby improving convenience.

[0041] It should be noted that the specific models and specifications of the air-source heat pump body 110, power connector 121, motor 140 and graphene heating plate 210 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0042] The power supply and principles of the air energy heat pump body 110, the power connector 121, the motor 140 and the graphene heating plate 210 are clear to those skilled in the art and will not be described in detail here.
