Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, in particular to a mobile air conditioner. Background Art

[0002] Air conditioners come in both floor-standing and wall-mounted styles. Both types consist of indoor and outdoor units. The indoor unit serves as the air outlet, with the user primarily controlling the air speed, wind force, and delivery of hot and cold air. The outdoor unit, the heart of the air conditioner, primarily cools and dissipates the high-pressure, high-temperature air exhausted from the indoor unit through its fan. This heat exchange occurs with the refrigerant circulating in the piping, repeatedly achieving internal cooling. When the indoor unit is cooling, the outdoor unit acts as a radiator and the indoor unit as an evaporator. The reverse is true when heating.

[0003] An existing patent, patent publication number CN220152845U, entitled "A Mobile Air Conditioner," discloses a portable air conditioner. The specification describes a transverse partition disposed within the air conditioner housing, a first fan and evaporator disposed above the transverse partition, a compressor, a water tank, and a heat exchanger disposed below the transverse partition, a condenser disposed within the water tank, the compressor, condenser, and evaporator being sequentially connected to form a circuit, and the heat exchanger's input and output pipes, which are each disposed within the water tank and connected by a water pump. This existing patent places the condenser within the water tank, exchanges heat with the water tank through the heat exchanger, and dissipates heat from the heat exchanger via a second fan, improving the condenser's heat dissipation efficiency. This allows for faster heat dissipation from the air conditioner, thereby increasing the lifespan and safety of the mobile air conditioner.

[0004] However, after the refrigeration work is completed, the evaporator located above the partition stops working, and refrigerant flows inside the evaporator, causing frost to form on the surface of the evaporator. After the frost on the evaporator surface melts into water, the inner cavity of the air conditioner remains humid for a long time, promoting the growth of bacteria. In the long run, the wind blown out by the air conditioner will affect the health of the user.

[0005] Therefore, the present application proposes a mobile air conditioner in which a large amount of frost will not form on the evaporator after the air conditioner stops working, so as to solve the above problems. Utility Model Content

[0006] This utility model is developed to address the problem of existing mobile air conditioners experiencing excessive defrosting on the evaporator after shutdown, resulting in a humid environment inside the air conditioner, which promotes bacterial growth and impacts user health.

It should be understood that this overview is not an exhaustive overview of the utility model.

[0025] Example 1, combined Figures 1-4 The present embodiment is described. A mobile air conditioner of the present embodiment includes an air conditioner housing 1, a first evaporator 4, a heat exchanger 5, a first fan 6, a second fan 7, a compressor 8, a first water tank 9 and a second water tank 10. A transverse partition 3 is provided in the air conditioner housing 1. The transverse partition 3 divides the air conditioner housing 1 into two cavities, an upper and a lower cavity. A louver vent 2 is provided on the air conditioner housing 1. The louver vent 2 is connected to the upper cavity of the air conditioner housing 1. The upper cavity of the air conditioner housing 1 is provided with a first evaporator 4, a first fan 6 and a first water tank 9. The first water tank 9 is provided with a first evaporator 4, a first fan 6 and a first water tank 9. A second evaporator 11 is provided, and a heat exchanger 5, a second fan 7, a compressor 8 and a second water tank 10 are provided in the lower cavity of the air-conditioning casing 1. A condenser 12 is provided in the second water tank 10. The compressor 8 is connected to the first evaporator 4 and the second evaporator 11 respectively through an incoming flow pipeline, and the compressor 8 is connected to the first evaporator 4, the second evaporator 11 and the condenser 12 respectively through a return flow pipeline. The second water tank 10 is connected to the heat exchanger 5 through a pipeline. Universal wheels are provided at the bottom of the air-conditioning casing 1, which facilitate the movement of the air conditioner.

[0026] After the air conditioner is turned on for cooling, the compressor 8 compresses the gas, compresses the low-pressure gas into high-pressure gas, and the high-pressure gas enters the condenser 12 through the second main inlet flow pipe 83. The condenser 12 condenses the refrigerant from gas to liquid, releasing heat. After the condenser 12 condenses the high-pressure gas into liquid, it enters the first inlet flow pipe 42 through the first main inlet flow pipe 82, and is finally transported to the first evaporator 4. The first inlet flow pipe 42 and the first main inlet flow pipe 82 are integrated as capillaries, which reduce the pressure of the refrigerant to the boiling point corresponding to the refrigerant, and reduce the pressure of the high-pressure refrigerant to low-pressure refrigerant, and enter the first evaporator 4. The first evaporator 4 evaporates the refrigerant from liquid to gas, absorbs heat to realize the cooling function, and the first fan 6 blows air toward the first evaporator 4, and the cold air is blown out from the louver air outlet 2 to realize the output of cold air.

[0027] A first water tank 9 is mounted on the inner side wall of the air conditioner housing 1. A second evaporator 11 is disposed in the first water tank 9. The input end of the second evaporator 11 is connected to a second inlet pipe 92, and the output end thereof is connected to a second return pipe 91. The second inlet pipe 92 is connected to the first inlet pipe 42 and the second main inlet pipe 83 via a second electromagnetic three-way valve 14. The second return pipe 91 is connected to the first return pipe 41 and the main return pipe 81 via a first electromagnetic three-way valve 13.

[0028] During the cooling process, the first solenoid three-way valve 13 controls the connection between the first return pipe 41 and the main return pipe 81, while the second solenoid three-way valve 14 controls the connection between the first inlet pipe 42 and the second main inlet pipe 83. When the air conditioner stops cooling, the first solenoid three-way valve 13 controls the connection between the main return pipe 81 and the second return pipe 91, while the second solenoid three-way valve 14 controls the connection between the first main inlet pipe 82 and the second inlet pipe 92. After cooling stops, refrigerant no longer flows into the first evaporator 4. Instead, refrigerant enters the second evaporator 11 through the first main inlet pipe 82 and the second inlet pipe 92. After absorbing heat in the second evaporator 11, the refrigerant flows through the output end of the second evaporator 11 through the second return pipe 91 and the main return pipe 81 back to the compressor 8, completing the cycle. The second evaporator 11, located in the first water tank 9, exchanges heat with the medium in the first water tank 9, accelerating the defrosting of the second evaporator 11. The defrosted surface of the second evaporator 11 does not cause moisture in the cavity within the air conditioner casing 1.

[0029] After the condenser 12 arranged in the second water tank 10 exchanges heat with the medium in the second water tank 10, the water pump 53 in the second water tank 10 is turned on, and the water pump 53 discharges the medium in the second water tank 10 into the heat exchanger 5 through the second output pipe 52. The second fan 7 is turned on to dissipate heat from the heat exchanger 5. The medium after dissipation flows back into the second water tank 10 through the second input pipe 51. Under the action of the second fan 7, the temperature of the heat exchange medium in the second water tank 10 is reduced.

[0030] Example 2, combined with Figures 1-4 This embodiment is described. A mobile air conditioner of this embodiment has a first output pipe 15 connected to the second input pipe 51, and a first input pipe 16 connected to the body of the second water tank 10. The first output pipe 15 and the first input pipe 16 respectively pass through the air conditioner casing 1 and are arranged outside the air conditioner. After the condenser 12 condenses the high-pressure gas input by the compressor 8 into liquid, a large amount of heat is released. After heat exchange with the medium in the second water tank 10, the temperature of the medium in the second water tank 10 increases. At this time, the water pump 53 is turned on and the water pump 53 discharges the medium in the second water tank 10 through the second output pipe 52 and then through the first output pipe 15. The discharged medium has a high temperature and can be connected to a heater, a water heater, or used directly. While the medium in the second water tank 10 is discharged, the medium is continuously input into the second water tank 10 through the first input pipe 16, forming a circulation of the medium in the second water tank 10. On the one hand, the temperature of the heat exchange medium in the second water tank 10 can be quickly reduced, thereby improving the heat exchange and cooling effect on the condenser 12, and on the other hand, the utilization effect of the heat exchange medium in the second water tank 10 is improved.

[0031] In order to improve the circulation efficiency in the second water tank 10, a solenoid valve can be installed on the second input pipe 51 and a pump body can be installed on the first output pipe 15 to block the exchange of the medium with the heat exchanger 5 and accelerate the flow rate of the medium in the first output pipe 15.

[0032] Heating pipes are also provided in the first water tank 9 and the second water tank 10. The heating pipes in the first water tank 9 prevent the second evaporator 11 from freezing due to the low temperature in the first water tank 9. When necessary, the heating pipes in the first water tank 9 are turned on to increase the temperature in the first water tank 9, and the heating pipes in the second water tank 10 are turned on to increase the temperature in the second water tank 10. When the temperature in the second water tank 10 is not enough to supply heat to the heater and water heater, the heating pipes in the second water tank 10 are turned on.

[0033] Due to the extremely cold weather in the north, the outdoor temperature is low in winter. The compressor of the split-type air-conditioning outdoor unit is affected by the external ambient temperature, and the old equipment affects the normal operation of the air-conditioning. However, the mobile air-conditioning compressor 8 of this embodiment is set indoors. When the heating function is turned on, it is not affected by the outdoor cold air and can operate normally.

[0034] This embodiment is only an illustrative description of the present application and does not limit its scope of protection. Those skilled in the art may also make partial changes to it. As long as they do not exceed the spirit of the present application, they are all within the scope of protection of the present application.
