[0045] With the development of social economy, clothing treatment equipment with a drying function has been widely used. Especially in areas with high humidity, the drying function of clothing treatment equipment with a drying function meets people's urgent need for drying clothes. Currently, clothing drying equipment on the market generally includes heat pump type and condensation type. Heat pump drying uses a heat pump compressor to pressurize and heat the refrigerant. The refrigerant is sent into the condenser to release heat. The condenser is connected to the air duct in the dryer to release dry air. The refrigerant enters the capillary tube from the condenser, and its pressure and temperature rapidly decrease, and then enters the evaporator. The evaporator is also connected to the drying air duct to turn the humid hot air into dry cold air. The operation of the above refrigerant, combined with the rolling of the drum in the clothing drying equipment and the air supply of the drying fan, realizes the effect of drying clothes. This equipment has a good drying effect, but the equipment cost is relatively high; condensation drying is to use a heater to heat the air to make it into dry hot air and send it into the drum in the clothing drying equipment. After passing through the clothes, it becomes humid hot air. After the humid hot air is introduced into the condensation pipe, it becomes dry cold air. Then, through the action of the fan, the dry cold air is sent to the heater to be heated and sent into the drum. In this way, the moisture of the clothes is continuously discharged to achieve the purpose of drying the clothes.
[0046] In the prior art, a drying device is connected to an air duct. Among them, air enters the evaporator through the front air duct. Inside the evaporator, the air is cooled, moisture condenses into water droplets from the air and is collected in a water tank. Subsequently, the air dehumidified and cooled by the evaporator enters the rear air duct, is heated to a suitable drying temperature through a condenser, becomes dry hot air, and re-enters the drying device to participate in the drying process. However, during the process of the gas entering the condenser from the evaporator, the gas is prone to disorder and form turbulence, which affects the air volume entering the cylinder, thereby reducing the drying efficiency of the entire drying device.
[0047] First, refer to Figure 1 , Figure 1 which is a schematic diagram of the overall structure of the drying device provided by the present invention. As Figure 1 shown, the drying device provided by the present invention is provided with a first installation area 01 and a second installation area 02. A wind guiding channel 03 is defined between the first installation area 01 and the second installation area 02. A plurality of wind guiding baffles 1 are arranged in the wind guiding channel 03. Among them, the wind guiding channel 03 has an air inlet end 031 communicating with the first installation area 01 and an air outlet end 032 communicating with the second installation area 02. The plurality of wind guiding baffles 1 are arranged at intervals perpendicular to the gas flow direction. Based on the above structural settings, during the process of the gas entering the second installation area 02 from the first installation area 01, the wind guiding baffles 1 in the wind guiding channel 03 guide the gas to be shunted, thereby reducing the unevenness of the air flow and avoiding the occurrence of turbulence. It should be noted that the present invention does not impose any restrictions on the specific structure and quantity of the wind guiding baffles 1, and those skilled in the art can set them according to actual usage requirements. For example, as Figure 1 shown, the number of the wind guiding baffles 1 can be two.
[0048] In this preferred embodiment, the wind guiding baffle 1 is inclined along the gas flow direction to change the air flow direction and enhance the guiding effect. Optionally, the inclination angle of the wind guiding baffle 1 is less than a preset value to avoid the inclination angle of the wind guiding baffle 1 being too large, thereby affecting the air volume entering the second installation area 02. It should be noted that the present invention does not impose any restrictions on the inclination angle of the wind guiding baffle 1, and those skilled in the art can set it according to actual usage requirements. Preferably, the inclination angle of the wind guiding baffle 1 can be 5°.
[0049] In this preferred embodiment, refer to Figure 2 , Figure 2 which is a schematic diagram of the structure of the wind guiding baffle in the drying device provided by the present invention. As Figure 2 shown, the thickness of the wind guiding baffle 1 smoothly decreases from the air inlet end 031 to the air outlet end 032. Since in the wind guiding channel 03, the gas flows from the air inlet end 031 to the air outlet end 032, therefore, setting the thickness of the wind guiding baffle 1 to smoothly decrease from the air inlet end 031 to the air outlet end 032 can reduce the wind resistance of the air flow and reduce the noise.
[0050] In this preferred embodiment, the first installation area 01 is an evaporator installation area, and the second installation area 02 is a condenser installation area, which is used to solve the problem of gas disorder during the process of the gas entering the condenser from the evaporator.
[0051] In this preferred embodiment, refer to Figure 3 , Figure 3 is a schematic structural diagram of the flow guide plate in the drying device provided by the present utility model. Combining Figure 1 and Figure 3 , the drying device provided by the present utility model includes a drying box 2. A flow guide plate 3 is arranged between the second installation area 02 and the drying box 2. Among them, the flow guide plate 3 has an air inlet 31 communicating with the second installation area 02 and an air outlet 32 communicating with the drying box 2. By arranging the flow guide plate 3, the gas can flow from the second installation area 02 to the drying box 2 along the direction of the flow guide plate 3. It should be noted that the present utility model does not impose any restrictions on the specific structure and material of the flow guide plate 3, and those skilled in the art can set it according to actual usage requirements. Optionally, the air inlet area at the air inlet 31 of the flow guide plate 3 is larger, and the air outlet area at the air outlet 32 is smaller, which can increase the air pressure when the gas flows into the drying box 2, thereby enhancing the drying effect and saving the drying time.
[0052] In this preferred embodiment, a plurality of flow guiding devices 4 are arranged on the flow guide plate 3 along the gas flow direction, so that the gas between the second installation area 02 and the drying box 2 can be shunted to reduce the wind resistance of the air flow and reduce the noise. Specifically, the flow guiding device 4 includes a plurality of first flow guiding ribs 41. The first flow guiding ribs 41 are close to the air inlet 31, and the plurality of first flow guiding ribs 41 are arranged at intervals perpendicular to the gas flow direction to preliminarily shunt the gas between the second installation area 02 and the drying box 2 and reduce the eddy current of the gas at the position close to the air inlet 31. At the same time, the flow guiding device 4 further includes a plurality of second flow guiding ribs 42. The second flow guiding ribs 42 are close to the air outlet 32, and the plurality of second flow guiding ribs 42 are arranged at intervals perpendicular to the gas flow direction to shunt the gas between the second installation area 02 and the drying box 2 again and reduce the eddy current of the gas at the position close to the air outlet 32. It should be noted that the present utility model does not impose any restrictions on the specific structure and quantity of the first flow guiding ribs 41 and the second flow guiding ribs 42, and those skilled in the art can set them according to actual usage requirements. For example, as Figure 3 shown, the number of the first flow guiding ribs 41 can be two, and the number of the second flow guiding ribs 42 can be three.
[0053] In this preferred embodiment, refer to Figure 4 and Figure 5 , among which, Figure 4 is a schematic structural diagram of the rear side plate in the drying device provided by the present utility model, Figure 5It is a schematic structural diagram of the convex part in the drying device provided by the present utility model. As Figure 4 and Figure 5 shown, the drying box 2 includes a rear side plate 21, and a convex part 22 is provided on the rear side plate 21. The convex part 22 includes a bottom surface 221 and a vertex 222. The bottom surface 221 is connected to the rear side plate 21, and the bottom surface 221 is arc-shaped and transitions towards the vertex 222. Among them, the convex part 22 is used to push the clothes towards the middle of the drying box 2, reduce the accumulation of clothes at the rear side plate 21, and avoid affecting the air flow exchange. Setting the bottom surface 221 to be arc-shaped and transitioning towards the vertex 222 can prevent the clothes from being wound around the convex part 22, thereby affecting the drying effect.
[0054] It should be noted that the above embodiments are only used to illustrate the principle of the present utility model and are not intended to limit the protection scope of the present utility model. Without deviating from the principle of the present utility model, those skilled in the art can adjust the above structure so that the present utility model can be applied to more specific application scenarios.
[0055] So far, the technical solution of the present utility model has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without deviating from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present utility model.
