Description

Technical Field

[0001] This utility model belongs to the field of air conditioner defrosting technology, and in particular relates to an energy-saving defrosting structure for air conditioners. Background Technology

[0002] An air conditioner is a device used to regulate indoor air temperature, humidity, cleanliness, and airflow speed to provide a comfortable indoor environment. It is widely used in homes, offices, shopping malls, and industrial sites. When an air conditioner is running in heating mode, the outdoor unit's heat exchanger (evaporator) will frost over due to the low temperature, requiring the use of defrosting equipment.

[0003] While current air conditioner defrosting structures can defrost heat exchangers, the defrosting effect is not complete due to the varying areas of the heat exchangers. Furthermore, the defrosting process cannot simultaneously deliver hot airflow to the defrosting area, thus failing to improve the defrosting effect and resulting in poor practical application performance. Therefore, an energy-saving defrosting structure for air conditioners is proposed. Utility Model Content

[0004] The purpose of this utility model is to propose an energy-saving defrosting structure for air conditioners in order to solve the problems of incomplete and poor defrosting effect of current air conditioner heat exchangers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving defrosting structure for air conditioners, comprising: a mounting frame, a drive motor fixedly mounted at one end of the mounting frame, an electric heating tube disposed inside the housing cavity of the mounting frame, a reciprocating screw fixedly mounted at one end of the output shaft of the drive motor, a slider mounted on the external thread of the reciprocating screw, negative pressure airbags disposed at both ends of the slider, an electric telescopic frame disposed on the bottom surface of the slider, and triangular side plates fixedly mounted on both outer walls of the electric telescopic frame;

[0006] The defrosting assembly and the touch-sensitive assembly are rotatably mounted on the inner side of the electric telescopic frame, and the touch-sensitive assembly is rotatably mounted on the side wall of the triangular side plate.

[0007] The defrosting assembly includes a mounting shaft, which is rotatably mounted in a rotating hole inside the electric telescopic frame. A meshing gear is fixedly mounted at one end of the mounting shaft, and a mounting side shell is fixedly mounted on the outer surface of the mounting shaft.

[0008] As a further description of the above technical solution:

[0009] The defrost brush is movably mounted inside the mounting side shell via a built-in spring, and two spring lifting frames are fixedly mounted on the bottom surface of the mounting frame.

[0010] As a further description of the above technical solution:

[0011] A rack is fixedly installed at the bottom of the spring lifting frame, and the meshing gear plate and the rack are meshed together.

[0012] As a further description of the above technical solution:

[0013] The pressure-sensitive assembly includes a mounting side shaft, which is rotatably mounted in a rotating hole provided on the side wall of the triangular side plate.

[0014] As a further description of the above technical solution:

[0015] One end of the mounting side shaft is fixedly mounted with a traveling wheel, which is in rolling connection with the bottom surface of the mounting frame.

[0016] As a further description of the above technical solution:

[0017] An installation plate is fixedly mounted on the outside of the mounting side shaft, and an extrusion roller is fixedly mounted on the bottom end of the installation plate.

[0018] As a further description of the above technical solution:

[0019] An air tube is provided on the bottom surface of the negative pressure airbag, and the squeezing roller is located below the negative pressure airbag.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. In this utility model, a movable and height-adjustable defrosting component is provided. Through this design, continuous cyclical defrosting of the air conditioner heat exchanger can be completed. The overall position and height of the defrosting brush can be continuously changed according to the overall surface area of ​​the heat exchange tube, which greatly improves the defrosting effect and comprehensiveness of the heat exchanger. At the same time, the defrosting brush can play a more effective ice-breaking role under the action of the built-in spring, further improving the defrosting effect.

[0022] 2. In this utility model, by providing a matching pressure component and a negative pressure airbag, the heating element inside the mounting frame is turned on during defrosting, increasing the air temperature inside the mounting frame and the negative pressure airbag. At this time, as the defrosting component continues to move, the traveling wheels can rotate continuously, controlling the mounting plate and the squeezing roller to rotate synchronously. When the squeezing roller rotates, it can complete the intermittent pressure on the negative pressure airbag. The pressured negative pressure airbag can continuously transfer the hot air downwards, and the transferred hot air can flow to the defrosting area, realizing the heating of the defrosting area, assisting the defrosting brush to defrost, and further improving the actual application effect of the overall equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In specific implementation, such as Figures 1-5 As shown, this utility model provides a technical solution: an energy-saving defrosting structure for air conditioners, including a mounting frame 2, a drive motor 1 fixedly mounted at one end of the mounting frame 2, an electric heating tube disposed inside the housing cavity of the mounting frame 2, a reciprocating screw 7 fixedly mounted at one end of the output shaft of the drive motor 1, a slider 8 mounted on the external thread of the reciprocating screw 7, negative pressure airbags 9 disposed at both ends of the slider 8, an electric telescopic frame 6 disposed on the bottom surface of the slider 8, and triangular side plates 11 fixedly mounted on both outer walls of the electric telescopic frame 6;

[0032] The defrosting assembly 4 and the touch-sensitive assembly 10 are rotatably mounted on the inner side of the electric telescopic frame 6, and the touch-sensitive assembly 10 is rotatably mounted on the side wall of the triangular side plate 11.

[0033] The defrosting assembly 4 includes a mounting shaft 41, which is rotatably mounted in a rotating hole inside the electric telescopic frame 6. One end of the mounting shaft 41 is fixedly mounted with a meshing gear disc 42, and a mounting side shell 43 is fixedly mounted on the outer surface of the mounting shaft 41.

[0034] Inside the mounting side shell 43, a defrosting brush 45 is movably mounted via a built-in spring 44. Two spring lifting frames 5 are fixedly mounted on the bottom surface of the mounting frame 2. A rack 3 is fixedly mounted at the bottom end of the spring lifting frame 5. The meshing toothed disc 42 and the rack 3 are meshed and connected to each other.

[0035] Before using the equipment, install it in the designated area and ensure that one end of the defrost brush 45 is in close contact with the surface of the air conditioner heat exchanger. During defrosting, turn on the drive motor 1 to drive the reciprocating screw 7 to rotate, and control the slider 8 to move back and forth. At the same time, the defrost assembly 4 can be driven to move back and forth. During this process, the meshing toothed disc 42 can mesh with the rack 3 and rotate, while driving the defrost brush 45 to rotate. The rotating defrost brush 45 can scrape off the frost on the surface of the heat exchanger. When it is necessary to change the cleaning height, control the electric telescopic frame 6 to change the height of the defrost brush 45.

[0036] like Figure 5 As shown, the pressure-sensitive assembly 10 includes a mounting side shaft 101, which is rotatably mounted in a rotating hole provided on the side wall of the triangular side plate 11. One end of the mounting side shaft 101 is fixedly mounted with a traveling wheel 104, which is in rolling connection with the bottom surface of the mounting frame 2. An mounting plate 102 is fixedly mounted on the outside of the mounting side shaft 101, and a squeezing roller 103 is fixedly mounted on the bottom end of the mounting plate 102. An air pipe is provided on the bottom surface of the negative pressure airbag 9, and the squeezing roller 103 is located below the negative pressure airbag 9.

[0037] During defrosting, the heating element inside the mounting frame 2 is turned on to increase the air temperature inside the mounting frame 2 and the negative pressure airbag 9. At this time, as the defrosting component 4 continues to move, the traveling wheel 104 can rotate continuously, and the mounting plate 102 and the squeezing roller 103 can rotate synchronously. When the squeezing roller 103 rotates, it can complete the intermittent contact pressure on the negative pressure airbag 9. The negative pressure airbag 9 that is contacted can continuously transfer the hot airflow downwards. The transferred hot airflow can flow to the defrosting area to achieve the heating of the defrosting area and assist the defrosting brush 45 in defrosting.

[0038] Working principle: Before use, install the equipment in the designated area, ensuring one end of the defrost brush 45 is in close contact with the surface of the air conditioner heat exchanger. During defrosting, activate the drive motor 1 to rotate the reciprocating screw 7, controlling the slider 8 to move back and forth. Simultaneously, this drives the defrost assembly 4 to move back and forth. During this process, the meshing toothed disc 42 engages with the rack 3 and rotates, simultaneously driving the defrost brush 45 to rotate. The rotating defrost brush 45 scrapes away the frost on the heat exchanger surface. When the cleaning height needs to be changed, control the electric telescopic frame 6 to adjust the defrost brush 45. The height is sufficient; during defrosting, the heating element inside the mounting frame 2 is turned on to increase the air temperature inside the mounting frame 2 and the negative pressure airbag 9. At this time, as the defrosting component 4 continues to move, the traveling wheel 104 can rotate continuously, and the mounting plate 102 and the squeezing roller 103 can rotate synchronously. When the squeezing roller 103 rotates, it can complete the intermittent contact pressure on the negative pressure airbag 9. The negative pressure airbag 9 that is contacted can continuously transfer the hot airflow downwards. The downward hot airflow can flow to the defrosting area to achieve the heating of the defrosting area and assist the defrosting brush 45 in defrosting.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
