Description

Technical Field

[0001] The invention relates to the technical field of defrosting of air-conditioning units, in particular to an air-conditioning unit with a defrosting mechanism. Background Art

[0002] When the air conditioner is in heating mode, the heat exchanger of the outdoor unit is in a heat absorption state, so that the moisture and dust in the surrounding air will condense on the coil of the heat exchanger together, blocking the heat exchange gap between the coils. If it is not cleaned in time, the outdoor unit will have insufficient heat exchange, affecting the normal operation of the air conditioner until the compressor shuts down. Specifically, the compressor of the outdoor unit compresses the refrigerant, and the compressed high-temperature gaseous refrigerant flows into the indoor unit, releasing heat to supply hot air to the user. At the same time, the refrigerant condenses and liquefies into a low-temperature liquid. The low-temperature liquid refrigerant flows from the indoor unit to the outdoor unit, and absorbs heat from the outdoor environment by evaporation in the heat exchanger of the outdoor unit, so that the temperature of the heat exchanger and the surrounding environment is reduced. The temperature of the outer surface of the heat exchanger is usually below 0 degrees Celsius. When the humidity of the external environment is high, frost often occurs, which affects the heating effect of the air conditioning system. Therefore, the heat exchanger of the outdoor unit should be defrosted.

[0003] However, there are some problems with defrosting of existing equipment. For example, a technical solution is disclosed in Patent No.: CN202311292819.5. When in use, this technical solution fully utilizes the heat generated by the compressor and the brush to defrost the evaporator. Although this operation can defrost the evaporator, there are some problems in actual use. During the defrosting process, the equipment only defrosts by hot air and a brush, and the frost will liquefy into water during the removal process. At this time, the water is adsorbed on the evaporator, and excess water may enter the chassis, which will cause the components in the chassis to become damp. At the same time, if the water adsorbed on the evaporator is mixed with dust, the surface of the evaporator will be covered with a layer of mud that cannot be cleaned, which will then cause the evaporation efficiency of the evaporator to decrease, thereby affecting the subsequent use of the equipment.

[0004] Based on this, the present invention designs an air conditioning unit with a defrosting mechanism to solve the above problems. Summary of the invention

[0029] See also Figure 1-Figure 7 , the present invention provides a technical solution:

[0030] An air conditioner unit with a defrosting mechanism comprises a casing 1, an evaporator 2 and a compressor 3 are arranged in the casing 1, a heat absorbing tube 4 is wound around the outside of the compressor 3, an adjusting mechanism 5 is fixedly connected to one end of the heat absorbing tube 4, a pump 10 and an induced draft fan 11 are installed on the adjusting mechanism 5, a speed regulating box 12 is installed on the casing 1, a first gear 13 is installed on the speed regulating box 12, the speed regulating box 12 and the adjusting mechanism 5 are connected in driving, a guide groove 14 is opened in the casing 1, a moving mechanism 15 is arranged in the casing 1, and a pump 10 and an induced draft fan 11 are installed on the adjusting mechanism 5. A driving mechanism 19 is installed, and the driving mechanism 19 is movably connected to the first gear 13 and the moving mechanism 15 respectively. A moving frame 24 is threadedly connected to the moving mechanism 15, and a wiping sponge 25 is installed on the moving frame 24. A supporting mechanism 26 is provided on the moving frame 24, and a guide pipe 31 is installed on the supporting mechanism 26. The guide pipe 31 is connected to the heat absorbing pipe 4 through, and a plurality of nozzles 32 are provided at one end of the guide pipe 31. An extrusion mechanism 33 is provided in the guide groove 14, and a filtering mechanism 36 is installed on the lower side of the casing 1;

[0031] During operation, the heat absorption tube 4 is wound around the outside of the evaporator 2. First, the driving mechanism 19 is controlled to mesh with the first gear 13. At this time, the driving mechanism 19 controls the rotating column 8 in the adjusting mechanism 5 to rotate, and then the adjusting plate 9 installed on the rotating column 8 is rotated. At this time, the adjusting plate 9 controls the guidance of the cavity 7. When the adjusting plate 9 and one of the cavities 7 are connected, the induced draft fan 11 introduces gas and allows the gas to enter the heat absorption tube 4. Then, the driving mechanism 19 and the moving mechanism 15 are controlled to mesh. Then, the driving mechanism 19 controls the moving mechanism 15 to move. When the moving mechanism 15 moves, the wiping sponge 25 contacts the evaporator 2 and wipes the frost on its surface. At this time, the gas heated by the evaporator 2 acts on the surface of the evaporator 2 through the nozzle 32, so that the frost on the surface of the evaporator 2 is melted. At the same time, the melted liquid water is adsorbed by the wiping sponge 25 to avoid liquid turbulence, thereby causing the parts inside the equipment to be wet. When the supporting mechanism 26 moves to the casing 1 When one side is moved, the supporting mechanism 26 is squeezed, and at the same time, the wiping sponge 25 is squeezed by the squeezing mechanism 33, so that the liquid in the wiping sponge 25 enters the filtering mechanism 36 along the guide groove 14. At this time, the filtering mechanism 36 filters the impurities in the liquid, and then controls the driving mechanism 19 to adjust the guide of the regulating mechanism 5 again, so that one side of the pump 10 is connected, and then the pump 10 adsorbs the clean water, and then it is heated again through the heat absorption tube 4. At this time, the heated liquid is sprayed out again through the nozzle 32 to spray on the surface of the evaporator 2. At this time, the hot water can not only quickly defrost the surface of the evaporator 2, but also the sprayed liquid can fully clean the surface of the evaporator 2, so as to ensure the cleanliness of the evaporator 2, thereby further improving the defrosting efficiency of the equipment and keeping the equipment clean. After the liquid is filtered, the liquid is located in the filtering mechanism 36, and people can collect and process the clean water in a unified manner, thereby further avoiding the waste of resources and improving the practicality and use efficiency of the equipment.

[0032] As a further solution of the present invention, the regulating mechanism 5 includes a regulating tube 6, a cavity 7, a rotating column 8 and an regulating plate 9. One end of the heat absorbing tube 4 is fixedly connected to the regulating tube 6. Two cavities 7 are provided in the regulating tube 6, one of which is connected to the induced draft fan 11, and the other is connected to the pump 10. The regulating tube 6 is rotatably connected to the rotating column 8, and the regulating plate 9 is installed on the rotating column 8.

[0033] During operation, when the driving mechanism 19 controls the rotating column 8 to rotate, the rotating column 8 controls the adjusting plate 9 to rotate. When the adjusting plate 9 rotates to one cavity 7, another cavity 7 is connected. At this time, the induced draft fan 11 passes through the cavity 7 and the heat absorption tube 4, so that the hot air can fully melt the frost. At the same time, when the adjusting plate 9 rotates in the other opposite direction, the pump 10 is connected with the heat absorption tube 4 through the cavity 7. At this time, the induced draft fan 11 is turned off, and the liquid sucked out by the pump 10 is heated through the heat absorption tube 4. At the same time, hot water is sprinkled on the evaporator 2, which can melt the frost on the evaporator 2 and clean the evaporator 2, thereby further improving the melting efficiency of the equipment and keeping the equipment clean.

[0034] As a further solution of the present invention, the moving mechanism 15 includes a threaded rod 16, a torsion spring 17 and a second gear 18. Two threaded rods 16 are rotatably connected in the housing 1. The two threaded rods 16 are transmission-connected. One of the threaded rods 16 is sleeved with a torsion spring 17, and one of the threaded rods 16 is mounted with a second gear 18.

[0035] During operation, when the driving mechanism 19 controls the second gear 18 to rotate, the second gear 18 controls the threaded rod 16 to rotate. At this time, the movable frame 24 threadedly connected to the threaded rod 16 moves. At the same time, when the movable frame 24 moves, the torsion spring 17 is compressed at the same time. When the driving mechanism 19 and the second gear 18 are disengaged, the movable frame 24 is reset, thereby repeating the work to keep the evaporator 2 clean and avoid the generation of frost and fog, thereby further improving the cleaning efficiency of the equipment.

[0036] As a further solution of the present invention, the driving mechanism 19 includes a driving motor 20, a telescopic rod 21, a third gear 22 and a half gear 23.

The third gear 22 and the half gear 23 are installed on the telescopic rod 21. The third gear 22 and the first gear 13 are movably engaged, and the half gear 23 and the moving mechanism 15 are movably engaged;

[0037] During operation, when the telescopic rod 21 is extended, the half gear 23 installed on the telescopic rod 21 is meshed with the second gear 18. At this time, the half gear 23 drives the moving mechanism 15 to move through the second gear 18, thereby effectively removing frost in the equipment and ensuring the cleanliness of the equipment. When the telescopic rod 21 is shortened, the third gear 22 is meshed with the first gear 13. At this time, the speed regulating box 12 controls the rotation of the rotating column 8, and then the adjusting plate 9 adjusts the channel of its cavity 7, thereby further improving the practicality and ease of use of the equipment.

[0038] As a further solution of the present invention, the support mechanism 26 includes a slide bar 27, a support plate 28, a first spring 29 and a pressure block 30. Two slide bars 27 are slidably connected to the mobile frame 24, and a support plate 28 is fixedly connected between the two slide bars 27. The first spring 29 is sleeved on the slide bar 27, and the pressure block 30 is fixedly connected to the support plate 28.

[0039] During operation, when the movable frame 24 moves to one side of the guide groove 14, the pressing block 30 contacts the side wall of the casing 1, and the slide rod 27 slides, and the spring is compressed, so that the wiping sponge 25 can fully contact the squeezing mechanism 33, so that the liquid in the wiping sponge 25 can be squeezed out, while ensuring the continuous use of the wiping sponge 25, and the water formed by frost can also be collected, thereby further improving the use efficiency of the equipment.

[0040] As a further solution of the present invention, the squeezing mechanism 33 is movably connected to the wiping sponge 25, and the squeezing mechanism 33 includes a second spring 34 and a squeezing plate 35. A plurality of second springs 34 are fixedly connected in the guide groove 14, and a squeezing plate 35 is fixedly connected between the plurality of second springs 34.

[0041] During operation, when the wiping sponge 25 and the squeezing plate 35 come into contact, as the moving mechanism 15 moves, the squeezing plate 35 can fully squeeze the wiping sponge 25. At the same time, with the elastic force of the second spring 34, the liquid in the wiping sponge 25 can be fully squeezed out, thereby ensuring the continuous use of the wiping sponge 25 and further improving the cleaning efficiency of the equipment.

[0042] As a further solution of the present invention, the filter mechanism 36 is connected to the guide groove 14, the pump 10 is connected to the filter mechanism 36, the filter mechanism 36 includes a water collecting box 37, a sewage chamber 38, a clean water chamber 39, a filter plate 40 and a debris removal port 41, and the lower side of the housing 1 is provided with a water collecting box 37, a sewage chamber 38 and a clean water chamber 39 are provided in the water collecting box 37, and a filter plate 40 is movably connected between the sewage chamber 38 and the clean water chamber 39;

[0043] During operation, when the liquid in the wiping sponge 25 contacts the squeezing mechanism 33, the liquid flows along the guide groove 14 into the water collecting tank 37. At this time, the liquid enters the sewage chamber 38 and is then filtered by the filter plate 40 to filter out impurities in the liquid. At the same time, the liquid can be pumped out and heated by the pump 10, and then cleaned and defrosted, thereby further improving the cleanliness of the equipment.

[0044] As a further solution of the present invention, the sewage chamber 38 is located on the upper side of the clean water chamber 39, and a debris removal port 41 is provided on one side of the water collecting tank 37;

[0045] During operation, since the height of the sewage chamber 38 is higher than that of the clean water chamber 39, the sewage will flow to the side of the clean water chamber 39, and then the sewage will be fully filtered. At the same time, when the sewage is filtered, the impurities remain in the sewage chamber 38. At this time, people can take out the impurities from the impurity removal port 41, thereby further improving the practicality and cleanliness of the equipment, and ensuring the reuse of the liquid.
