Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, and in particular to an air cooler that can be powered by both AC and DC power. Background Technology

[0002] An evaporative air cooler is a device that brings fresh air and lowers the temperature in workshops, public places, commercial and entertainment venues. It is an environmentally friendly product that requires no compressor, refrigerant, or copper pipes. Its main components are a cooling fan, an evaporative cooling pad, and a drive motor. Its working principle is that a circulating water pump continuously draws water from a tank and sprays it evenly onto the evaporative cooling pad through a water distribution system. The hot outdoor air exchanges heat with the water, thus achieving a cooling effect.

[0003] Currently, existing air coolers only support AC power and can only be used where there is a power outlet. This not only limits the mobility of the air coolers but also restricts their application in outdoor locations where there is no power outlet. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cooler that can be powered by both AC and DC, so as to solve the problem that the cooler cannot be used in places where there is no power socket.

[0005] The objective of this utility model is achieved through the following technical solution:

[0023] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-4 As shown, this utility model provides a dual-power AC / DC air cooler, including a housing 1, a cooling system 2, a power module 3, a DC power connector 4, and a battery 5. The cooling system 2 is located inside the housing 1. The power module 3 includes a power input port 301 and an AC / DC converter 302. The power input port 301 is used to connect to an external AC power source. The AC / DC converter 302 is used to convert AC power to DC power. The first output terminal of the AC / DC converter 302 is connected to the cooling system 2, and the second output terminal of the AC / DC converter 302 is connected to the battery 5. The battery 5 is located outside the housing 1 and is connected to the cooling system 2 through the DC power connector 4.

[0025] The battery 5 can directly power the air conditioning system 2. The battery 5 is located outside the casing 1, which can reduce the size and weight of the air conditioner. Users can choose whether to use the battery 5 according to the actual power connection. The battery 5 outputs DC power, which can be used in outdoor and other scenarios, making it more convenient. In the case of AC power support, the power input port 301 is connected to an external AC power source. The AC-DC converter 302 converts the AC power to DC power, which can then be output to the air conditioning system 2 and the battery 5 respectively. That is, the air conditioner can be used while the battery 5 is being charged.

[0026] It should be noted that when the air cooler is powered by AC power, the DC charging system can automatically detect whether a battery 5 is connected at the DC power connector 4. If a battery 5 is detected, it can charge the battery 5. If no battery 5 is detected, the charging system is disconnected.

[0027] Furthermore, when using DC power, the evaporative air cooler features reverse polarity protection and short-circuit protection, making it safer. Simultaneously, the control system automatically detects the charge level of battery 5 when powered by DC. When the charge level of battery 5 is low, the control system automatically disconnects the DC power supply to protect the battery 5 and the lifespan of the evaporative air cooler.

[0028] The cooling system 2 includes a DC motor and a cooling fan. The first input terminal of the DC motor is connected to the first output terminal of the AC-DC converter 302, and the second input terminal of the DC motor is connected to the output terminal of the battery 5 through the DC power connector 4. The DC motor is used to drive the cooling fan.

[0029] The casing 1 has louvers 6 on one side and ventilation openings 7 on the other three sides. One side of the louvers 6 is the air outlet of the air cooler, and the ventilation openings 7 on the other three sides are mainly the air inlets of the air cooler. A mounting bracket 8 is fixed inside the casing 1, and the air cooler is fixed on the mounting bracket 8. The air cooler rotates towards the side of the louvers 6.

[0030] This utility model also includes a water tank 9, a water distribution system, and multiple evaporative cooling pads 10. The water tank 9 is fixed to the bottom of the casing 1. The water distribution system is used to spray the water in the water tank 9 onto the evaporative cooling pads 10. The evaporative cooling pads 10 are fixed to the inner wall of the casing 1. The water tank 9 stores water, and the water distribution system sprays the water in the water tank 9 onto the evaporative cooling pads 10.

[0031] The water distribution system includes a water pump and water pipes. The water pump is fixed inside the water tank 9 and is used to transport water from the water tank 9 to the water pipes. The output end of the water pipes is fixedly connected to a water distributor 11, which is fixed to the inner top of the casing 1 and distributes water downwards to the evaporative cooling pad 10. Specifically, the water in the water tank 9 is pumped into the water pipes, then guided by the water pipes to the water distributor 11, and finally sprayed onto the evaporative cooling pad 10.

[0032] The housing 1 includes a frame 101 and a cover plate 102. The water tank 9 is fixed on the frame 101, and the cover plate 102 is fixedly closed on the top of the frame 101. A receiving groove 12 is provided on the side wall of the top of the frame 101, and the top of the evaporative cooling pad 10 is inserted into the receiving groove 12.

[0033] A support frame 13 is fixed to the inward side wall of the bottom of the frame 101. The bottom of the evaporative cooling pad 10 is fixed to the support frame 13. A water collection tank 14 is provided in the middle of the support frame 13, and a through hole 15 is provided at the bottom of the water collection tank 14. Excess water on the evaporative cooling pad 10 flows into the water collection tank 14 from its bottom, and finally flows back into the water tank 9 through the through hole 15.

[0034] The bottom wall of the water collection tank 14 slopes towards the through hole 15. The downward slope of the bottom wall makes it easier to guide water to the through hole 15.

[0035] A guide plate 16 is fixed to the side wall of the water tank. A guide groove 17 is formed on the top surface of the guide plate 16. The guide groove 17 is located directly below the through hole 15 and has openings at both ends. Water flowing out of the through hole 15 falls directly into the guide groove 17, and then falls down along the side wall of the guide plate 16 from the openings at both ends of the guide groove 17. This avoids water falling directly into the water tank 9, thus avoiding the sound of water dripping and making it quieter.

[0036] There are multiple guide plates 16, which extend downward to the bottom wall of the water tank 9. The number of through holes 15 corresponds to the number of guide plates 16. The specific shape of the guide plates 16 is not limited, as long as the surface is smooth and allows water droplets to slide off easily.

[0037] This invention enables the air cooler to function as both an AC and DC power source by setting up a power module 3, a DC power connector 4, and a storage battery 5. In outdoor environments, the storage battery 5 can be used to power the air cooler, while in environments where AC power is supported, AC power can be used directly to power the air cooler and simultaneously charge the storage battery 5. This invention allows the air cooler to adapt to a wider range of application scenarios.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
