[0002] A cold water fan is a household appliance that combines fan and cooling functions. It pumps water from a tank to a wet curtain through a built-in water pump. When the fan in the cold water fan draws in outside air, the outside air flows through the wet curtain and is discharged from the air outlet of the cold water fan. The moisture on the wet curtain evaporates when air flows through it, absorbing heat to reduce the air temperature, thereby reducing the temperature of the air at the air outlet.

The function of the condenser is to release the heat of the high-temperature and high-pressure refrigerant gas in the pipe, turning it into a low-pressure and low-temperature refrigerant. The function of the evaporator is to make the low-pressure and low-temperature refrigerant contact with the external environment, so that the vapor of the refrigerant becomes liquid, producing a strong cooling effect.

[0004] In the prior art, the refrigeration system needs to be arranged in the housing of the cooling fan, which makes the heat dissipation effect of the condenser poor; and the heat dissipation effect of the condenser will restrict the operation of the refrigeration system, thereby affecting the air temperature at the air outlet of the cooling fan.

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The present application embodiment discloses a refrigeration system. Figure 1 The refrigeration system in the embodiment of the present application is applied to a cooling fan device. The cooling fan device includes a housing 1, a refrigeration system and an air supply system (not shown in the figure); since the air supply system is not the main invention point of the present embodiment, and there are many ways to implement the air supply system in the prior art; in the present embodiment, the specific structure of the air supply system is not elaborated.

[0038] Reference Figure 1 and Figure 2 The housing 1 is provided with a housing cavity for accommodating the refrigeration system and the air supply system. The housing 1 includes an upper housing 11 and a lower housing 12 connected to each other. The main structure of the refrigeration system is fixed to the lower housing 12, and the air supply system is mainly fixed to the upper housing 11. In this embodiment, the cross-sectional area of ​​the lower housing 12 is larger than the cross-sectional area of ​​the upper housing 11. The upper housing 11 includes an air inlet and an air outlet 13 arranged opposite to each other. Due to the display perspective, in the drawings of the present application specification, the upper housing 11 only displays the air outlet 13.

[0039] The refrigeration system pumps low-temperature water to the air outlet system and the air supply system.

[0040] The air supply system includes a wet curtain and a fan. The fan of the air supply system inhales external air through the air inlet, so that the external air flows through the wet curtain and is discharged from the air outlet 13 of the upper shell 11. The moisture on the wet curtain evaporates when the air flows through, absorbing heat to reduce the air temperature, thereby reducing the temperature of the air at the air outlet 13. Therefore, the operation of the cold water fan can reduce the temperature in the environment and increase the air humidity, thereby improving the indoor air quality and the comfort of the user.

[0041] Reference Figure 2 and Figure 3 The refrigeration system includes a water supply component 2, a refrigeration component 3 and a cooling component 4; the water supply component 2 is used to pump low-temperature water to the wet curtain in the air supply system; the refrigeration component 3 is used to reduce the temperature of the water pumped to the air supply system; the cooling component 4 is used to cool the temperature of the refrigeration component 3 to improve the refrigeration effect of the refrigeration component 3 on the water.

[0042] Reference Figure 2 and Figure 3 The water supply assembly 2 includes a first water tank 21, a second water tank 22, and a second water pump 23 which are connected in sequence. The first water tank 21 is installed on the side of the upper shell 11 close to the second shell 1, and the second water tank 22 is fixedly arranged on the side of the lower shell 12 close to the upper shell 11, and the volume of the first water tank 21 is greater than the volume of the second water tank 22. In this embodiment, the first water tank 21 is fixedly connected to the upper shell 11, and a water injection tank body is provided on the top of the upper shell 11. The water injection tank body is connected to the first water tank 21 through a pipeline, so that the user can add water to the first water tank 21. The second water tank 22 is fixedly connected to the shell 1, and the water flows into the second water tank 22 through the first water tank 21. The second water pump 23 is fixedly arranged at the bottom of the lower shell 12, and the second water pump 23 pumps the water in the second water tank 22 to the wet curtain of the air supply system.

[0043] Reference Figure 2 and Figure 3 In this embodiment, a partition plate 121 is provided at the bottom of the lower shell 12, thereby dividing the bottom of the lower shell 12 into a first trough body 122 and a second trough body 123. The area of ​​the first trough body 122 is larger than that of the second trough body 123, and the second water pump 23 is arranged in the first trough body 122.

[0044] It is worth noting that the water pumped into the wet curtain will not evaporate completely; part of the water will be collected into the first water tank 21 again under the action of gravity, thereby reducing the loss of water in the first water tank 21. That is, the first water tank 21, the second water tank 22, the second water pump 23 and the wet curtain form a first circulation subsystem; so that the water supply component 2 can continuously supply water to the wet curtain.

[0045] Reference Figure 3 and Figure 4 The refrigeration assembly 3 includes a compressor 31, a condenser 32 and an evaporator 33 which are connected in sequence. The compressor 31 is fixed in the second tank body 123, and the fixing method of the compressor 31 and the first tank body 122 can be bolted or snap-fitted. In this embodiment, the compressor 31 is fixedly connected to the second tank body 123 by bolts. The condenser 32 is installed in the second tank body 123, and the condenser 32 includes a mounting frame 321 and a condensing pipe 322. The mounting frame 321 is fixedly connected to the bottom of the tank of the second tank body 123 by bolts, and the condensing pipe 322 is fixedly installed on the mounting frame 321. The evaporator 33 is arranged in the second water tank 22, and the evaporator 33 is used to cool the water in the second water tank 22.

[0046] Reference Figure 3 and Figure 4 The working principle of the refrigeration component 3 is as follows: the compressor 31 sucks in low-pressure refrigerant and compresses it into high-pressure gas, thereby increasing the temperature and pressure of the refrigerant. The condenser 32 releases heat from the high-temperature, high-pressure refrigerant gas in the pipe, turning it into a low-pressure, low-temperature refrigerant. The evaporator 33 makes the low-pressure, low-temperature refrigerant contact with the external environment, so that the vapor of the refrigerant becomes liquid, producing a strong cooling effect.

[0047] Reference Figure 2 and Figure 3 , that is, the water flows into the second water tank 22 through the first water tank 21. The capacity of the second water tank 22 is small, so that the cooling effect of the evaporator 33 on the water can be improved to cool the water pumped to the wet curtain. Subsequently, the second water pump 23 is used to pump the water in the second water tank 22 into the wet curtain, thereby improving the cooling effect of the water in the wet curtain on the air and reducing the problem of the air at the air outlet 13.

[0048] Reference Figure 2 and Figure 3 It is worth noting that the compressor 31 , the condenser 32 and the evaporator 33 together constitute a second circulation subsystem, so that the refrigeration component 3 can always cool the water in the second water tank 22 .

[0049] However, since the refrigeration assembly 3 is arranged in the lower housing 12 of the cooling fan, the heat dissipation effect of the condenser 32 is poor. The heat dissipation effect of the condenser 32 will restrict the operation of the refrigeration system, thereby affecting the air temperature at the cooling fan outlet 13. Therefore, the embodiment of the present application adopts the cooling assembly 4 to improve the heat dissipation effect of the condenser 32, so as to improve the cooling effect of the refrigeration assembly 3 on the water in the second water tank 22, and reduce the temperature of the water pumped to the air supply system.

[0050] Reference Figure 2 , Figure 3 and Figure 5 The cooling assembly 4 includes a solenoid valve 41, a first pipe 42, a sprayer 43, a water collecting tank body, a three-way pipe 45, a circulation pipe 46, a first water pump 47, a float switch 48 and a cooling fan 49. The sprayer 43 is arranged on the side of the condenser 322 away from the second tank body 123, and the sprayer 43 is fixedly connected to the mounting frame 321. The sprayer 43 and the mounting frame 321 can be fixed in a plug-in manner, a bolt connection, etc. In this embodiment, the water collecting tank body is played by the second tank body 123 to reduce the installation of components; in other embodiments, the water collecting tank body can also be fixed in the second tank body 123.

[0051] Reference Figure 2 and Figure 3 In this embodiment, the sprayer 43 is connected to the mounting frame 321, and the sprayer 43 is connected to the wet curtain through the first pipe 42. Most of the water recovered by the wet curtain flows back to the first water tank 21, and part of the water flows to the sprayer 43 through the first pipe 42. The solenoid valve 41 is arranged on the first pipe 42, and the solenoid valve 41 is used to control the flow of water in the first pipe 42. In this embodiment, the sprayer 43 is a water pipe, one end of which is connected to the first pipe 42, and the other end of the water pipe is sealed; a plurality of water holes 431 are opened on the side of the water pipe close to the condenser 322, and the water in the water pipe flows to the surface of the condenser 322 through the water holes 431. In other embodiments, the sprayer 43 can also be a water box with a through hole. The wet curtain water is sprayed onto the condenser 322 through the sprayer 43, and the second tank 123 is used to receive the water flowing through the condenser 322.

[0052] Reference Figure 2 and Figure 5 The tee is installed on the first pipeline 42, and the tee pipe 45 includes a first branch pipe 451, a second branch pipe 452 and a third branch pipe 453 that are connected. The first branch pipe 451 and the second branch pipe 452 are both connected to the first pipeline 42, and the first branch pipe 451 and the second branch pipe 452 are located on the same straight line. The third branch pipe 453 is connected to the first water pump 47 through the circulation pipe 46. The first water pump 47 is bolted to the first tank body 122, and the first water pump 47 is used to extract water from the second tank body 123.

[0053] Reference Figure 2 and Figure 3 The float switch 48 is arranged in the second tank body 123, and the float switch 48 is used to control the operation of the first water pump 47 and the solenoid valve 41; when the water in the water collecting tank body 44 reaches the designed water level, the float switch 48 floats up to control the solenoid valve 41 to close, and controls the first water pump 47 to start running.

[0054] The cooling fan 49 is fixedly connected to the side wall of the mounting frame 321 , and the cooling fan 49 is used for air cooling the condenser tube 322 .

[0055] Reference Figures 2 to 5 The working principle of the cooling assembly 4 is as follows: a portion of the water recovered by the wet curtain flows to the sprayer 43 through the first pipe 42. The water in the paint sprayer flows through the outer periphery of the condenser 322 through the water-permeable hole 431 at the bottom, thereby cooling the condenser 322 in a water-cooling manner, improving the heat dissipation effect of the condenser 322, and improving the cooling effect of the refrigeration assembly 3 on the water in the second water tank 22. On the one hand, the cooling fan 49 has an air cooling effect on the condenser 322, and the cooling fan 49 is conducive to the evaporation of the water on the surface of the condenser 322, so as to further improve the cooling effect of the water on the condenser 322 and improve the heat dissipation performance of the condenser 322.

[0056] Reference Figures 2 to 5 , the water flowing through the outer peripheral wall of the condenser tube 322 falls to the second tank body 123 and is collected. When the water in the second tank body 123 is collected to the designed water level, the float switch 48 in the second tank body 123 floats up to trigger the switch, thereby closing the solenoid valve 41 and turning on the first water pump 47. The first water pump 47 pumps the water in the second tank body 123 to the sprinkler 43 through the circulation pipe 46.

[0057] Reference Figures 2 to 5 Thus, the sprayer 43 , the second tank body 123 , the first water pump 47 and the circulation pipe 46 constitute a third circulation subsystem, so that the water body can continuously cool the condenser tube 322 to improve the heat dissipation performance of the condenser tube 322 .

[0058] When the water in the second tank 123 evaporates naturally and the water around the condenser 322 evaporates, causing the water level in the bottom of the second tank to drop, the float switch 48 drops, and the solenoid valve 41 is activated to close the first water pump 47, so that the water on the wet curtain is replenished into the second tank 123 through the first pipe 42.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
