Description

Technical Field

[0001] This utility model relates to the field of evaporative air cooler technology, and in particular to an evaporative air cooler that provides rapid cooling. Background Technology

[0002] Current evaporative air coolers mainly consist of a water tank, an air box, a water pump, and a control circuit. The air box is mounted on the water tank and includes a casing and a fan. The fan is housed inside the casing. The front of the casing has an air outlet, while the sides and back have air inlets. A wet curtain is installed inside the air inlets. A water spray trough is located on the top of the casing, with spray holes at the bottom corresponding to the wet curtain. The water spray trough is connected to the water tank via the water pump. The water pump and fan are electrically connected to the control circuit. Its working principle is as follows: the water pump draws water into the water spray trough, and the water flows to the spray holes, wetting the wet curtain below. When air from the air inlet passes through the wet curtain, the relatively warm air exchanges heat with the curtain, and then the air is blown out from the air outlet by the fan, achieving the purpose of cooling. These air coolers have a large air volume, low energy consumption, and better cooling effect than ordinary fans. They are mainly suitable for outdoor cooling, cooling of temporary structures, and cooling of locations with temporary power supply.

[0003] To further enhance the cooling effect of the evaporator, some users put ice cubes into the water tank to lower the water temperature and improve the cooling effect.

[0004] Chinese Patent Publication No. CN112682884A, published on April 20, 2021, discloses a novel air cooler structure, including a housing with a cooling section and a fan installed in the cooling section. A cavity is located below the cooling section. Several ventilation openings are provided near the cooling section. Water-absorbing and filtering fibers are arranged around the cooling section and placed inside the housing. An evaporation pipe is installed in the cooling section, and a water pump, a water tank, and a compressor are installed in the cavity. The water pump draws water from the water tank to wet the water-absorbing and filtering fibers. The fan rotates and draws airflow from outside the housing through the ventilation openings, passing through the moistened water-absorbing and filtering fibers to form moisture inside the cooling section. The compressor drives the condensed liquid to exchange heat with the air in the cooling section through the evaporation pipe, vaporizing and absorbing heat. This, combined with the moisture inside the cooling section, achieves dual cooling. The fan then discharges the airflow from the cooling section outside the housing. This structure actually places the evaporator at the air outlet. Since the air outlet area is large, the evaporator is also relatively large. Therefore, a high-power compressor is required to achieve refrigeration. Its energy consumption and cost are relatively high, making it uneconomical and unsuitable for the above-mentioned applications.

[0005] Therefore, there is a need for an evaporative air cooler that can improve cooling performance while keeping overall cost and energy consumption low. Utility Model Content

[0011] As a further embodiment, one end of the cold water coil is connected to the outlet of the water pump via a water pipe, and the other end of the cold water coil is connected to a three-way solenoid valve. The other two ends of the three-way solenoid valve are respectively connected to the water spray tank and the atomizing head. The atomizing head is located on the front of the housing and above the air outlet.

[0012] As a further embodiment, the micro compressor refrigeration system is located on the upper part of the housing and near the bottom of the water spray tank.

The cooling fan is used to dissipate heat from the condenser. The micro compressor and the cooling fan are electrically connected to the control circuit.

[0013] As a further embodiment, the housing is composed of a front panel, a rear panel, a top cover, and two side panels. The water spray trough is located on the top cover, and the top of the water spray trough is also provided with an outer cover. The rear panel and the two side panels are equipped with wet curtains on their inner sides. The air outlet is located on the front panel. The rear panel and the side panels are respectively provided with rear air inlets and side air inlets corresponding to their respective wet curtains. The rear panel and the two side panels are also provided with water collection boxes at the lower end corresponding to the wet curtains. The bottom of the water collection boxes is provided with a drain outlet, which is connected to the wastewater trough. The upper side of the front panel is provided with a cavity, and the micro compressor refrigeration system is located in the cavity. The side panels are provided with heat dissipation holes corresponding to the cavity, and the heat dissipation holes are connected to the cavity. The cooling fan is located inside the heat dissipation holes.

[0014] As a further embodiment, the water storage tank is equipped with a partition that divides the interior of the water storage tank into a water storage tank and a wastewater tank. The wastewater tank is directly below the wet curtain. The height of the partition is lower than the height of the side wall of the water storage tank. The water pump's inlet is connected to the water storage tank.

[0015] As a further embodiment, the partition and the sidewall of the water storage tank are respectively provided with an inner drain outlet and an outer drain outlet on the same axis. The inner drain outlet connects the water storage tank and the wastewater tank, and the outer drain outlet leads to the outside. The diameter of the inner drain outlet is smaller than the diameter of the outer drain outlet. It also includes a sealing assembly, which includes a plug for sealing the inner drain outlet, a cover for sealing the outer drain outlet, and a connecting rod, with the connecting rod connecting between the plug and the cover.

[0016] As a further embodiment, the top cover is also equipped with an ultraviolet lamp that irradiates ultraviolet light into the water tank, and the ultraviolet lamp is electrically connected to the control circuit.

[0019] The beneficial effects of this utility model are as follows:

[0020] (1) The micro compressor refrigeration system of this utility model is used to cool the water in the water tank. Since the water volume in the water tank is small, the power required for cooling is low. The small volume and low power micro compressor refrigeration system can meet its requirements, avoiding excessive increase in the cost and energy consumption of the cooling fan, so as to meet the needs of its commonly used occasions and achieve the effect of rapid cooling.

[0021] (2) The micro compressor refrigeration system of this utility model can also cool the water in the atomizing head, and can also achieve the effect of rapid cooling.

[0022] (3) The wastewater tank of this utility model can collect the water that has been sprayed on the wet curtain first. After the wastewater is purified by sedimentation, the relatively clean water will overflow from the top of the wastewater tank into the water storage tank after the tank is full. This makes the water used to spray on the wet curtain relatively clean. At the same time, since the water purified by sedimentation in the wastewater tank can be reused, the capacity of the water storage tank is not greatly reduced after the wastewater tank occupies the space of the water storage tank, ensuring that the water storage tank can be used for a long time after it is full of water.

[0023] (4) The ultraviolet lamp of this utility model irradiates the water in the water spraying tank. Since the water spraying tank has a small space and a small amount of water, it has a better sterilization effect after being irradiated by the ultraviolet lamp, which reduces the growth of bacteria in the water and on the wet curtain and reduces the chance of the wet curtain becoming moldy.

[0040] The top cover 3 is also equipped with an ultraviolet lamp 6 that irradiates ultraviolet light into the water tank 32, and the ultraviolet lamp 6 is electrically connected to the control circuit.

[0041] The bottom of the water tank 32 is provided with a transparent cover 33, and the ultraviolet lamp 6 is installed inside the transparent cover 33.

[0042] The bottom of the top cover 3 has an opening corresponding to the bottom of the water spray tank 32. A transparent cover 33 is installed on the opening 39 and is sealed to fit the opening. The top cover 3 has a light shield 61 corresponding to the opening. The light shield 61 is used to prevent the light from the ultraviolet lamp 6 from shining into the box and then passing through the air outlet.

[0043] One edge of the outer cover 31 is hinged to the top cover 3. A magnetic switch 25 is provided on the line that connects the ultraviolet lamp 6 to the control circuit. The magnetic switch 25 is located on the side opposite to the hinge of the top cover 3 and the outer cover 31 and on the outside of the water spray tank 32. A magnetic block 37 is provided on the other edge opposite to the hinge of the outer cover 31. When the outer cover 31 is opened, the magnetic block 37 moves away from the magnetic switch 25, and the magnetic switch 25 disconnects the circuit of the ultraviolet lamp 6.

[0044] The edge of the light-shielding plate 61 is provided with an elastic buckle, and the inner wall of the opening is provided with a buckle position corresponding to the elastic buckle. The elastic buckle and the buckle position are fastened and fixed.

[0045] The front panel 2 has an air outlet 21 with a guide vane. The front panel 2 has a control panel 22 and a water inlet 24 above and below the air outlet 21, respectively. The control panel 22 is electrically connected to the control circuit, and the water inlet 24 is flipped and connected to a cover plate 23.

[0046] The water spray tank 32 has interconnected diversion channels 35 on its rear side and left and right sides. The water spray holes 351 are located at the bottom of the diversion channels 35. The water spray tank 32 and the diversion channels 35 are separated by a boss. The top of the boss is provided with an overflow channel 34, which connects the upper parts of the water spray tank 32 and the diversion channels 35. The water pump 9 is a submersible pump, which is installed in the water storage tank 1. The water spray tank 32 is provided with a nozzle 38, which is connected to the submersible pump through a water pipe 91.

[0047] Its working principle is as follows: After opening the cover plate 23, the user can insert the water supply pipe into the water inlet 24 to supply water into the water storage tank 13. When the water level reaches the high position shown on the water gauge 11, the water supply is stopped. The fan is started, and the airflow enters the cabinet after passing through the wet curtain and is blown out of the air outlet 21 by the fan. After starting the water pump 9, the water pump 9 pumps the water in the water storage tank 13 to the water spray tank 32. The water spray tank 32 sprays water onto the wet curtain 8 at the air inlet through the water spray hole 351, so that the air passing through the wet curtain 8 exchanges heat with the water and cools down.

[0048] If rapid cooling is required, the micro compressor refrigeration system 30 is activated. Water entering the water bath 32 passes through the cold water coil 306 and exchanges heat with the evaporator tube 304 in the hot water tank 305, achieving rapid cooling of the water in the water bath 32. The low-temperature water is then sprayed onto the wet curtain 8, significantly reducing the temperature of the air passing through it. The water in the hot water tank 305 is pure water or other refrigerant to prevent scale buildup on the evaporator tube surface.

[0049] Alternatively, users can choose spray cooling by controlling the passage of the three-way solenoid valve 307 so that the water in the cold water coil 306 is sprayed out only through the atomizing head 40, which can also cool down quickly.

[0050] During the process of spraying water through the wet curtain, the ultraviolet lamp 6 can be turned on to irradiate the water in the water tank 32, reducing the chance of bacterial growth in the water. The water that has been sprayed through the wet curtain 8 falls into the water collection box 20 and is introduced into the wastewater tank 14 through the drain port 201 at the bottom of the water collection box 20.

[0051] After the water passing through the wet curtain 8 settles in the wastewater tank 14, the particulate matter in the water is located at the bottom layer, and the purified water after the particulate matter has settled is located at the top layer. When the wastewater tank 14 is full, the purified water overflows into the storage tank 13 and is reused.

[0052] When draining water, unscrew the cover 17 of the outer drain outlet 12. The cover 17 drives the plug 18 away from the inner drain outlet 152 via the connecting rod 19. Therefore, the water in the water storage tank 13 and the water in the wastewater tank 14 can be drained together.

[0053] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
