Description

Technical Field

[0001] This utility model relates to the field of air conditioning fan technology, specifically to a cooling and heating air conditioning fan. Background Technology

[0002] Evaporative air conditioning fans (hereinafter referred to as air conditioning fans) are energy-saving cooling products. Their principle involves installing a water evaporation carrier at the air inlet of the unit, with a water tank at the bottom. A water pump inside the tank pumps water from the tank to a lower water tank, spraying it onto the evaporation carrier and wetting it. The fan operates at high speed, creating negative pressure inside the unit, drawing in outside air through the air inlet. The air passes through the evaporation carrier, causing the water to vaporize at room temperature. The evaporation absorbs heat, cooling both the water and the air. Unvaporized water flows back to the water tank for reuse, while the cooled air is blown out through the duct and outlet, providing a direct cooling sensation. Because it uses a regular fan instead of a compressor, it has low energy consumption and low cost, making it popular in hot summers. In contrast, air conditioning fans are a single-season product, suitable only for hot summers, and are idle for a long time throughout the year, resulting in wasted time and resources.

The drain outlet 8.1 allows the water added by the user to flow downwards to the water evaporation carrier and finally into the water tank. See [link / details]. Figure 5 and Figure 8 As shown.

[0064] like Figure 6 As shown, the rear shell 10 forms a hollow mounting groove 10.2 facing inward. A mesh-like axial air inlet 10.1 is formed on the mounting groove 10.2. The mounting groove 10.2 is used to house the water evaporation carrier 23. A water outlet 10.5 communicating with the mounting groove 10.2 is provided above it, allowing water to pass through. A drain trough 10.3 communicating with the mounting groove 10.2 is provided below it, for draining water.

[0065] A rear mesh 9 with a grid or perforated structure is also installed on the outer side of the axial air inlet 10.1 of the rear shell 10. The rear mesh 9 is located behind the side shells I6 and II11, and is a plate-like structure with a grid or perforated structure made of engineering plastic. The rear mesh 9 has an air inlet I9.1, which serves to allow air to enter and provide protection. Figure 3 and Figure 4 As shown.

[0066] The water evaporation carrier 23 used in this invention is located inside the rear shell 10 and is not limited to absorbent materials such as wet curtains or sponges. Its function is to allow water to be evenly distributed on a plane and to circulate. See [link / details]. Figure 4 and Figure 8 As shown.

[0067] like Figure 4 and Figure 7As shown, a rotating rod 24 is also provided on the lower surface of the water receiving box 27. This rod has a handle-like structure and is divided into a water pump fixing end 24.1 and a foolproof end 24.2. After rotation, it is used to fix the water pump assembly 26, ensuring that the water pump assembly 26 does not cause uneven contact between the machine body and the surface when the machine is laid flat. The drain pipe 25 is located below the water receiving box 27 and is a common corrugated pipe or silicone pipe. Its function is to ensure that the water flowing from the water receiving box 27 can stably enter the water tank 5 without generating excessive noise or splashing. The water pump assembly 26 is located inside the water tank 5 and is preferably a vane pump, used to draw water into the water storage chamber 8.2 in the top cover 8. The water receiving box 27 is located below the water evaporation carrier 23. The water receiving box 27 is provided with a water receiving cavity 27.1, a water pump fixing cavity 27.2, and a drain outlet II 27.3. The water receiving cavity 27.1 is used to collect the water flowing down from the water evaporation carrier 23 and guide it to the water tank 5 through the drain pipe 25 connected to the drain outlet II 27.3. The water pump fixing cavity 27.2 is used to place the water pump here, which can be fixed by rotating the rod 24.

[0068] The present invention is equipped with a fan blade that serves to circulate air and a water evaporation component that circulates water. The lower part consists of a water pump assembly and a water tank for storage.

[0069] like Figure 8 As shown, when using the cool air mode, the user can open the top cover 7 and add water to the water storage chamber 8.2 of the top cover 8. Under the action of gravity, the water flows through the drain outlet I8.1 to the water evaporation carrier 23. After the water is evenly distributed on the water evaporation carrier 23, it continues to flow down to the water collection box 27. After being collected through the water collection chamber 27.1 of the water collection box 27, it flows into the water tank 5 through the drain outlet II27.3. The fan blades are working, the heating element is not working, and the water pump assembly is working. The negative pressure generated by driving the fan blades drives the air through the air inlet I9.1. The air passes through the water evaporation carrier 23 and is humidified. Then it enters the body through the axial air inlet 10.1 and is finally blown out through the air outlet I2.3. The air is humidified by water and can be used to cool people and humidify the room.

[0070] like Figure 9 As shown, when using the hot air mode, the user does not need to add water. The fan blades and heating element are working, but the water pump assembly is not working. No water will flow onto the water evaporation carrier, and the air will not be humidified. At this time, the air enters the unit from the air inlet I9.1, is heated by the heating element, and is then blown out from the air outlet I2.3. The air is heated by the heating element and is warm, which can be used for heating and indoor drying.

[0071] like Figure 10As shown, when using the hot air humidification mode, the user adds water, the fan blades work, the heating element works, and the water pump assembly works. At this time, the air enters the machine body from the air inlet I9.1 and the air is humidified. The humidified air is then heated by the heating element and blown out from the air outlet I2.3. The air is humidified by water and heated by the heating element, so the air is warm and moist, which can be used for heating and humidification and is less likely to cause dry skin.

[0072] When the wind direction needs to be adjusted, motor I17 works, driving pinion 12 to rotate. Pinion 12 meshes with gear groove 2.2 on air outlet regulating grid 2, driving air outlet regulating grid 2 to rotate. When the wind passes through grid 2.1 on air outlet regulating grid 2, it forms a certain angle with grid 2.1, thus achieving the purpose of changing the wind direction.

[0073] To increase the temperature of the blown air, the air duct can be made into a closed cylindrical structure to increase the contact between the air and the heating element.

[0074] This utility model is a multi-functional device that can provide heating in winter, cooling in summer, humidifying when the air is dry, and dehumidifying when the air is humid. It saves users the cost of purchasing multiple products, and its storage capacity is smaller than that of multiple products, saving storage space and providing users with a more comfortable indoor temperature and humidity environment.

[0075] Any aspects not covered in this utility model are applicable to the prior art.

[0076] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
