Description

Technical Field

[0001] The utility model patent relates to the technical field of air-conditioning evaporators, and mainly relates to an air-conditioning evaporator with a self-cleaning function. Background Art

[0002] The function of the air conditioning evaporator is to utilize the liquid low-temperature refrigerant to evaporate easily under low pressure, turn into steam and absorb the heat of the cooled medium to achieve the purpose of refrigeration. It relies on the fan to force the air in the warehouse to flow through the cooling pipes in the box for heat exchange, so that the air is cooled, thereby achieving the purpose of lowering the warehouse temperature. As a result, the air conditioning evaporator needs to have one side facing the wind during the actual installation process, so it must be in contact with the outside world. However, long-term use will cause a lot of dust to be contaminated, which not only affects the overall heat exchange efficiency, but also greatly reduces the service life of the equipment. However, the existing air conditioning evaporator is relatively troublesome to clean, and the steps are cumbersome. In this regard, we propose an air conditioning evaporator with a self-cleaning function. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides an air-conditioning evaporator with a self-cleaning function. The screw rod is driven to rotate by a rotating motor, thereby driving the nut to move, and then driving the moving block to move, so that the cleaning cotton cleans the heat dissipation fins. During the cleaning process, dust and sewage are sucked into the dust storage cavity by the dust removal motor, and the airflow generated by the dust removal motor enters the water storage cavity, so that the pressure in the water storage cavity is increased, and the water in the water storage cavity flows out through the drainage pipe to clean the heat dissipation fins. When returning, the pressure relief valve is opened to keep the water storage cavity normal, and the dust removal motor continues to start, which can speed up the drying of the heat dissipation fins. The device can not only effectively clean the evaporator, but also speed up the drying speed of the evaporator, thereby avoiding low heat exchange efficiency due to unclean cleaning, affecting the user experience.

Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0022] For example, please refer to Figure 1-4 , an air conditioner evaporator with a self-cleaning function, comprising an evaporator 10, a plurality of heat dissipation fins 11 being arranged on the top of the evaporator 10, a moving mechanism 20 being connected to both sides of the top of the evaporator 10, a cleaning device 30 being connected to one side of the moving mechanism 20, the cleaning device 30 comprising a moving block 31 connected to one side of the moving mechanism 20, a dust removal motor 32 connected to one side of the inside of the moving block 31, a drainage pipe 33 connected to the other side of the moving block 31 and a cleaning cotton 34 connected to the bottom of the moving block 31, a plurality of protrusions being arranged at the bottom of the moving block 31, and the protrusions being staggered with the heat dissipation fins 11;

[0023] A water storage cavity 311 is provided on one side of the moving block 31 , and a dust storage cavity 312 is provided on the other side of the moving block 31 . The top of the dust storage cavity 312 is connected to a dust removal motor 32 .

[0024] It should be noted that, in the embodiment, the moving block 31 is moved so that the cleaning cotton 34 cleans the cooling fins 11. During the cleaning process, dust and sewage are sucked into the dust storage cavity 312 through the dust removal motor 32. The airflow generated by the dust removal motor 32 enters the water storage cavity 311, thereby increasing the pressure in the water storage cavity 311 and causing the water in the water storage cavity 311 to flow out through the drainage pipe 33 to clean the cooling fins 11.

[0025] For example, please refer to Figure 1 The moving mechanism 20 includes a rotating motor 21 connected to both sides of the top of the evaporator 10, a screw rod 22 connected to the driving end of the rotating motor 21, and a nut 23 connected to one side of the screw rod 22, and one side of the nut 23 is connected to a moving block 31.

[0026] It should be noted that, in the embodiment, the rotating motor 21 drives the screw rod 22 to rotate, thereby driving the screw nut 23 to move, and further driving the moving block 31 to move, so as to achieve cleaning.

[0027] For example, please refer to Figure 3 An air outlet pipe is provided on one side of the dust removal motor 32 , the outlet of the air outlet pipe is located in the water storage cavity 311 , and one side of the air outlet pipe is connected to a filter screen 321 .

[0028] It should be noted that, in the embodiment, the filter 321 prevents dust from entering the water storage cavity 311, and the airflow generated by the dust removal motor 32 enters the water storage cavity 311 through the air outlet pipe, thereby increasing the pressure in the water storage cavity 311 and causing the water in the water storage cavity 311 to flow out through the drainage pipe 33 to clean the cooling fins 11.

[0029] For example, please refer to Figure 4 A plurality of feed ports are provided on one side of the dust storage cavity 312, and a guide plate 314 is provided on one side of the feed port.

[0030] It should be noted that, in the embodiment, the guide plate 314 plays a role in guiding air flow, so as to facilitate the suction of dust and sewage into the dust storage cavity 312.

[0031] For example, please refer to Figure 1-2 A pressure relief valve 40 is provided on one side of the water storage chamber 311 .

[0032] It should be noted that, in the embodiment, the pressure relief valve 40 releases the pressure in the water storage cavity 311 to prevent the water in the water storage cavity 311 from flowing out when cleaning is not required.

[0033] For example, please refer to Figure 2 , T-shaped sliders 313 are fixed on both sides of the bottom of the moving block 31;

[0034] T-shaped slide grooves 12 are provided on both sides of the top of the evaporator 10 , and the groove body of the T-shaped slide groove 12 is slidably connected with the T-shaped sliding block 313 .

[0035] It should be noted that, in the embodiment, the T-shaped sliding block 313 enhances the stability of the moving block 31 .

[0036] For example, please refer to Figure 1-3 The drainage pipe 33 is C-shaped, and the water inlet of the drainage pipe 33 is located at the bottom of the water storage cavity 311.

[0037] It should be noted that, in the embodiment, the water inlet of the drainage tube 33 is located at the bottom of the water storage cavity 311 so that the water in the water storage cavity 311 can be pressed out of the drainage tube 33 .

[0038] The specific operation mode of the utility model is as follows:

[0039] The above-mentioned air conditioner evaporator with self-cleaning function drives the screw rod 22 to rotate by rotating the motor 21, thereby driving the screw nut 23 to move, and then driving the moving block 31 to move, so that the cleaning cotton 34 cleans the heat dissipation fins 11. During the cleaning process, dust and sewage are sucked into the dust storage cavity 312 by the dust removal motor 32, and the airflow generated by the dust removal motor 32 enters the water storage cavity 311, so that the pressure in the water storage cavity 311 increases, and the water in the water storage cavity 311 flows out through the drainage pipe 33 to clean the heat dissipation fins 11;

[0040] During the return journey, the pressure relief valve 40 is opened to keep the water storage cavity 311 normal, and the dust removal motor 32 continues to start, which can accelerate the drying of the heat dissipation fins 11.

[0041] The above-described embodiments only express the implementation methods of the present application, but for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
