Description

[0002] The clothes dryer is a household appliance that uses electric heating to evaporate and dry the moisture in clothes. That is, the clothes dryer achieves rapid drying of clothes through hot air circulation. The clothes drying device is one of the core components of the clothes dryer.

[0003] In related technologies, the clothes drying device usually includes a shell, a fan, a heating element, and an air duct. The air generated by the fan is heated by the heating element and output to the drying area through the air duct module, causing the moisture in the clothes to evaporate. However, when the hot air is transported through the air duct and output from the air outlet, the air outlet generally has a certain length. When the hot air flows through the air outlet, it does not flow through all positions of the air outlet at the same time, causing the hot air to concentrate on some positions of the air outlet and blow out, resulting in uneven air output, which causes some clothes to be too dry or some clothes to be not dry enough, resulting in poor drying effect of the clothes dryer.

[0056] In view of the problems described in the background art, the present invention provides a clothes drying device and dryer that can produce more uniform airflow, thereby enabling the dryer to dry clothes more effectively.

[0057] The technical solution of this application will be described in detail below with reference to specific embodiments and accompanying drawings.

[0058] This application provides a clothing drying device, such as... Figure 1 and Figure 2 As shown, the clothes drying device includes a housing 1, an air duct 2, a fan 3, a heating element 4, and several guide elements 5. The housing 1 has an air inlet 1a and an air outlet 1b. The air duct 2, fan 3, and heating element 4 are all disposed within the housing 1, and the several guide elements 5 are disposed within the air duct 2. The air duct 2 connects the air inlet 1a and the air outlet 1b. The fan 3 is used to introduce airflow from the air inlet 1a into the air duct 2 and send it out from the air outlet 1b. The heating element 4 is disposed in the airflow path. The several guide elements 5 are used to guide the airflow passing through the air duct 2 to different areas of the air outlet 1b.

[0059] In this embodiment, the air duct 2, fan 3, and heating element 4 are all disposed within the housing 1. The air duct 2 connects the air inlet 1a and the air outlet 1b. The fan 3 is used to introduce airflow from the air inlet 1a into the air duct 2 and send it out from the air outlet 1b. The heating element 4 is disposed in the airflow path. Thus, air can be introduced into the air duct 2 by the fan 3, and the air can circulate along the air duct 2 and be heated by the heating element 4, so that the air sent out from the air outlet 1b is hot air, which allows the moisture in the clothes to evaporate, thereby drying the clothes relatively quickly.

[0060] Several guide elements 5 are installed in the air duct 2 to guide the airflow through the air duct 2 to different areas of the air outlet 1b. This avoids the hot air from concentrating in a localized area of ​​the air outlet 1b when it flows out of the air outlet 1b. It allows the hot air to flow out of the air outlet 1b more evenly, so that the hot air can be blown more evenly onto the clothes in the dryer, effectively improving the drying effect of the dryer.

[0061] The fan 3 can be installed in the housing 1 near the air inlet 1a, near the air outlet 1b, or at any position in the air duct 2, as long as it can introduce airflow from the air inlet 1a into the air duct 2. There are no restrictions on this.

[0062] The heating element 4 can be placed near the air inlet 1a, near the air outlet 1b, or at any position in the air duct 2, as long as it can heat the air that is about to be delivered from the air outlet 1b. There are no restrictions on this.

[0063] In addition, the number of guide elements 5 can be one, two or more, and there is no limitation here.

[0064] Optionally, such as Figures 1-3 As shown, the guide member 5 divides the air duct 2 into sections along the length of the air duct 2 (e.g., ...). Figure 3 Multiple sub-air ducts 21a are distributed in the direction shown in the middle (x). The air inlets of the multiple sub-air ducts 21a are interconnected, and the air outlets of the multiple sub-air ducts 21a correspond to different areas of the air outlet 1b.

[0065] This allows hot air to be delivered to all areas of the air outlet 1b, making the hot air more evenly distributed from the air outlet 1b, thus improving the drying effect of the dryer.

[0066] The number of sub-wind channels 21a is two, three or more, and is not limited here.

[0067] The flow guide 5 divides the air duct 2 into multiple sub-air ducts 21a distributed along the length of the air duct 2. This can be implemented in various ways. In one possible implementation, such as... Figure 3As shown, there are multiple air guides 5, which are spaced apart along the length of the air duct 2. Therefore, the spacing between any two adjacent air guides 5 can be set as needed, making the airflow from the outlet 1b more uniform and effectively improving the drying effect of the dryer.

[0068] The number of guide components 5 can be two, three, or more, and is not limited here.

[0069] For example, there are three guide elements 5, which are spaced apart along the length of the air duct 2 to divide the air duct 2 into four sub-air ducts 21a, so that the air outlet 1b can be divided into four corresponding areas, thereby allowing the air to be blown out of the air outlet 1b evenly.

[0070] In another implementation where the air guide 5 divides the air duct 2 into multiple sub-air ducts 21a distributed along the length direction of the air duct 2, the air guide 5 may include a connecting plate and multiple air guide protrusions disposed on the connecting plate. The connecting plate extends along the extension direction of the air duct 2, and the multiple air guide protrusions are spaced apart on the connecting plate along the extension direction of the air duct 2. Thus, by connecting the connecting plate into the air duct 2, the air duct 2 can be divided into multiple sub-air ducts 21a, which is easy to implement.

[0071] Optionally, when there are multiple guide elements 5, and the multiple guide elements 5 are spaced apart along the length of the air duct 2, the distance between two adjacent guide elements 5 increases sequentially along the flow direction of the airflow in the air duct 2.

[0072] This allows the airflow in the multiple sub-ducts 21a to be more consistent, resulting in more uniform airflow from the air outlet 1b and further improving the drying effect of the dryer.

[0073] In this context, the distance between two adjacent guide members 5 increases sequentially along the flow direction of the airflow in the air duct 2. This can be either that the distance between two adjacent guide members 5 gradually increases along the flow direction of the airflow in the air duct 2, or that the increase in the distance between two adjacent guide members 5 is inconsistent. No limitation is imposed here.

[0074] Optionally, such as Figure 3 As shown, the air duct 2 includes a first air duct wall 21 and a second air duct wall 22 arranged opposite to each other. Both the first air duct wall 21 and the second air duct wall 22 extend along the length direction of the air duct 2. The first ends 51 of a plurality of guide members 5 are connected to the first air duct wall 21, and the second ends 52 of the plurality of guide members 5 form an air supply gap with the second air duct wall 22. The air outlet 1b is arranged close to the first air duct wall 21.

[0075] Therefore, when the air flows in the air duct 2, part of the air can flow to the sub-air duct 21a located near the air inlet 1a of the air duct 2, and the other part of the air can flow to the sub-air duct 21a away from the air inlet 1a through the air supply gap, so that hot air can be delivered to each area of ​​the air outlet 1b, which effectively improves the drying effect of the dryer.

[0076] The first air duct wall 21 and the second air duct wall 22 can be smoothly connected, or they can be connected by a third air duct wall. Alternatively, one side of the first air duct wall 21 can be connected to one side of the second air duct wall 22 through the third air duct wall, and the other side of the first air duct wall 21 can be connected to the other side of the second air duct wall 22 through the fourth air duct wall. No limitation is made here.

[0077] In addition, such as Figure 3 As shown, along the flow direction of the airflow in the duct 2, the first end 51 of the guide member 5 is located downstream of the second end 52.

[0078] Therefore, dead corners that the airflow cannot reach within the sub-duct 21a can be effectively avoided, and the airflow at certain locations of the air outlet 1b can be reduced due to dead corners that the airflow cannot reach within the sub-duct 21a, thereby making the airflow from the air outlet 1b more uniform.

[0079] like Figure 3 As shown, the guide 5 is an arc-shaped plate, with the concave surface of the arc-shaped plate facing the first air duct wall 21 and the convex surface of the arc-shaped plate facing the second air duct wall 22.

[0080] This effectively reduces the resistance of the airflow within the duct 2 and the influence of the guide 5 on the air speed, allowing the airflow from the outlet 1b to reach the clothes more quickly, enabling the moisture on the clothes to evaporate more promptly and further improving the drying effect of the dryer.

[0081] The curved plate can be spherical, cylindrical, or parabolic; there are no restrictions on its shape.

[0082] Optionally, such as Figures 4-6 As shown, the air outlet 1b is located above the first air duct wall 21, and the upper edge of the guide 5 protrudes from the upper edge of the first air duct wall 21.

[0083] This allows hot air to flow out from the area near the lower edge of the air outlet 1b, making the airflow from the air outlet 1b more even and thus improving the drying effect of the dryer.

[0084] The upper edge of the guide 5 protruding from the upper edge of the first air duct wall 21 can be 0.5cm, 1cm, 1.5cm, etc., and is not limited here.

[0085] In addition, such as Figure 6 As shown, along the bottom of the air duct 2 towards the air outlet 1b, the distance between the first air duct wall 21 and the second air duct wall 22 gradually increases.

[0086] This allows the air in the air duct 2 to gradually diffuse as it flows toward the air outlet 1b, ensuring that airflow can reach all areas of the air outlet 1b. Furthermore, the air flowing out of the air outlet 1b can quickly diffuse into the drying area of ​​the dryer, thus allowing the air to flow more evenly to the clothes in the drying area and further improving the drying effect of the dryer.

[0087] Optionally, such as Figure 3 As shown, along the flow direction of the airflow in the air duct 2, the distance between the first air duct wall 21 and the second air duct wall 22 gradually decreases.

[0088] Therefore, along the flow direction of the airflow in the air duct 2, the cross-sectional area of ​​the air duct 2 can become smaller and smaller, so that the air pressure in the air duct 2 can gradually increase along the flow direction of the airflow in the air duct 2, so that the wind speed flowing from each area of ​​the air duct 2 to the air outlet 1b can be more consistent, thereby making the air outlet 1b more uniform and further improving the drying effect of the dryer; and the hot air flowing out from each position of the air outlet 1b can have a large wind speed, so that the hot air can be blown to the clothes in the dryer more quickly, thereby making the clothes dry faster and further improving the drying effect of the dryer.

[0089] In some embodiments, such as Figure 7 and Figure 8 As shown, the clothes drying device also includes an air guide 6, which is disposed above the air duct 2. The air guide 6 is inclined upward, the lower edge of the air guide 6 is connected to the second air duct wall 22, and the upper edge of the air guide 6 abuts against the upper edge of the air outlet 1b.

[0090] Therefore, the air guide 6 can be tilted above the first air duct wall 21 so that when the air flows from the air duct 2 to the air outlet 1b, it can be guided to the position of the air outlet 1b by the air guide 6. In addition, the air can be diffused upward along the air guide 6 so that the hot air flowing out from the air outlet 1b can be diffused to the clothes located above the air outlet 1b more quickly, effectively improving the drying efficiency.

[0091] The air guide 6 can be an arc-shaped plate structure, a flat plate structure with a flat surface, or it can include interconnected arc-shaped plate structures and flat plate structures. There are no limitations here, and the specific configuration can be set according to actual needs.

[0092] In some embodiments, such as Figure 8 andFigure 9 As shown, the housing 1 includes a first side plate 122 and a second side plate 123 disposed opposite to each other. The air outlet 1b includes a first air outlet 11b and a second air outlet 12b. The first air outlet 11b is disposed on the first side plate 122, and the second air outlet 12b is disposed on the second side plate 123. There are multiple air ducts 2, including a first air duct 2a and a second air duct 2b. Both the first air duct 2a and the second air duct 2b are provided with a guide 5. The first air duct 2a is disposed close to the first side plate 122 and communicates with the first air outlet 11b. The second air duct 2b is disposed close to the second side plate 123 and communicates with the second air outlet 12b.

[0093] This allows hot air to flow out through the first air outlet 11b and the second air outlet 12b, so that the hot air can be blown towards the clothes in the dryer from different directions, thereby making the hot air blow more evenly onto the clothes and thus making the drying effect of the dryer better.

[0094] The number of air ducts 2 can be three, four or more, and the number of air outlets 1b can be three, four or more, so that hot air can flow out from more different air outlets, thereby making the hot air blow more evenly onto the clothes that need to be dried in the dryer, effectively improving the drying effect of the dryer.

[0095] In addition, an air outlet grille can be provided at the position of the first air outlet 11b on the first side plate 122 to make the air outlet 11b more uniform. An air outlet grille can also be provided at the position of the second air outlet 12b on the second side plate 123 to make the air outlet 12b more uniform.

[0096] Optionally, such as Figure 3 As shown, the second air duct wall 22 of the first air duct 2a and the second air duct wall 22 of the second air duct 2b are arranged opposite to each other, and the ends of the second air duct wall 22 of the first air duct 2a and the second air duct wall 22 of the second air duct 2b near the air inlet 1a are connected to each other.

[0097] This allows the first air duct 2a and the second air duct 2b to be arranged side by side, which facilitates the setting of the air duct 2. It also allows the air flowing through the first air duct 2a and the air flowing through the second air duct 2b to have approximately the same flow distance. As a result, the hot air flowing out of the first air outlet 11b and the hot air flowing out of the second air outlet 12b can have approximately the same wind speed, which allows the hot air to be blown more evenly onto the clothes that need to be dried in the dryer, effectively improving the drying effect of the dryer.

[0098] In addition, the second air duct wall 22 of the first air duct 2a and the second air duct wall 22 of the second air duct 2b are connected to each other at the end near the air inlet 1a, so that the air inlet end of the first air duct 2a and the air inlet end of the second air duct 2b are the same air inlet end, which simplifies the structure of the air duct 2 and makes the air duct 2 easy to implement.

[0099] The second air duct wall 22 of the first air duct 2a and the second air duct wall 22 of the second air duct 2b can be arranged opposite each other in the horizontal direction, and the first side plate 122 and the second side plate 123 can be arranged opposite each other in the horizontal direction. That is, the first air outlet 11b and the second air outlet 12b can be arranged opposite each other in the horizontal direction, so that the hot air flowing out from the first air outlet and the hot air flowing out from the second air outlet can travel approximately the same distance to the drying area of ​​the dryer. This allows the hot air to be blown more evenly onto the clothes that need to be dried in the dryer, effectively improving the drying effect of the dryer.

[0100] Optionally, along the flow direction of the airflow in the air duct 2, the distance between the second air duct wall 22 of the first air duct 2a and the second air duct wall 22 of the second air duct 2b gradually increases.

[0101] Therefore, the second air duct wall 22 of the first air duct 2a and the second air duct wall 22 of the second air duct 2b can be arranged to form a V-shaped structure. This allows the cross-sectional area of ​​the first air duct 2a and the second air duct 2b to gradually decrease along the direction of airflow. This makes it easier for the air pressure in the first air duct 2a and the second air duct 2b to change too much. As a result, the hot air flowing out from the first air outlet 11b and the hot air flowing out from the second air outlet 12b can both have a high wind speed, allowing the hot air to be blown onto the clothes more quickly, thereby effectively improving the drying efficiency of the dryer.

[0102] In some embodiments, such as Figure 8 and Figure 9 As shown, the housing 1 includes a main housing 11 and a waterproof cover 12. The top of the main housing 11 is provided with a mounting hole, and the waterproof cover 12 is placed over the mounting hole. The waterproof cover 12 includes a top plate 121 and a plurality of side plates disposed on the top plate 121. The plurality of side plates are arranged around the top plate 121. The plurality of side plates include a first side plate 122 and a second side plate 123 disposed opposite to each other along a first direction. The first side plate 122 and / or the second side plate 123 gradually tilt outward from top to bottom.

[0103] This effectively reduces the chance of water droplets from clothes falling into the air duct 2, reduces the loss of hot air energy caused by water droplets entering the air duct 2, improves the drying effect of the dryer, and effectively reduces the situation of water droplets flowing onto the heating element 4, thus improving the safety of the dryer.

[0104] In addition, the first side plate and / or the second side plate 123 gradually tilt outward from top to bottom, which can guide water droplets to flow to the outside of the housing 1, effectively reducing the probability of water droplets flowing into the air duct 2, further reducing the probability of water droplets flowing to the heating element 4, and further improving the safety of the dryer; and it can also make the hot air blown out from the first air outlet 11b and the hot air blown out from the second air outlet 12b diffuse upward, so that the hot air can be blown to the clothes more quickly, further improving the drying efficiency of the dryer.

[0105] It should be explained that the first side plate 122 and / or the second side plate 123 gradually tilt outward from top to bottom means that the first side plate and / or the second side plate 123 gradually tilt away from the center of the shell 1 from top to bottom.

[0106] Optionally, such as Figure 9 As shown, the multiple side plates also include a third side plate 124 and a fourth side plate 125 arranged opposite to each other along the second direction, and the top plate 121 is an arc-shaped plate that can guide water to the third side plate 124 and the fourth side plate 125.

[0107] Therefore, the dripping water droplets can be guided to the third side plate 124 and the fourth side plate 125 through the top plate 121, which effectively prevents water droplets from flowing into the first air outlet 11b on the first side plate 122 into the first air duct 2a, and from flowing into the second air outlet 12b on the second side plate 123 into the second air duct 2b. This avoids the loss of hot air energy due to water droplets entering the air duct 2, effectively improving the drying effect of the dryer, and also effectively preventing water droplets from flowing onto the heating element 4, thus improving the safety of the dryer.

[0108] The second direction can be perpendicular to the first direction. For example, if the first direction is horizontal, the second direction can be another horizontal direction perpendicular to the first direction. Alternatively, the angle between the second direction and the first wind direction can be 45°, 60°, etc. There is no limitation here, as long as it can prevent water droplets from being guided to the first side plate 122 and the second side plate 123. There is no limitation here.

[0109] In addition, the side of the top plate 121 near the first side plate 122 can protrude from the first side plate 122, which can effectively reduce the probability of water droplets dripping into the first air duct 2a through the first air outlet 11b on the first side plate 122. The side of the top plate 121 near the second side plate 123 can protrude from the second side plate 123, which can effectively reduce the probability of water droplets dripping into the second air duct 2b through the second air outlet 12b on the second side plate 123. This further reduces the probability of water droplets flowing onto the heating element 4 and improves the safety of the dryer.

[0110] In some embodiments, the heating element 4 is disposed at one end of the air duct 2 near the air inlet 1a, there is a gap between the heating element 4 and the bottom wall of the air duct 2, and the portion of the bottom wall of the air duct 2 near the air inlet 1a gradually slopes downward along the direction of the heating element 4 pointing towards the air inlet 1a.

[0111] Therefore, even if water droplets flow into the air duct 2 through the air outlet 1b, they can flow to the air inlet 1a of the air duct 2 through the gap between the heating element 4 and the bottom wall of the air duct 2, effectively preventing water droplets from flowing onto the heating element 4, thus enabling the dryer to have a high level of safety.

[0112] The heating element 4 and the bottom wall of the air duct 2 can be connected by multiple wooden blocks, with a gap between two adjacent wooden blocks.

[0113] In addition, there may be gaps between the heating element 4 and other inner walls of the air duct 2. This is not limited here, and can be set according to the actual situation.

[0114] In other embodiments, the fan 3 includes an axial flow fan 3, a mixed flow fan 3, a dual axial flow fan 3, or a centrifugal fan 3. This allows for more uniform air intake by the fan 3, ensuring stable airflow within the duct 2, resulting in more uniform hot airflow from the outlet 1b, and reducing noise levels, thus improving the user experience.

[0115] In addition, the fan blades of the blower 3 can be thicker, which allows the blower 3 to generate greater wind pressure and air volume, thereby allowing more hot air to be blown onto the clothes faster and more effectively improving the drying efficiency of the dryer.

[0116] The heating element 4 mentioned above can be either an electric heating wire or a PTC (Positive Temperature Coefficient) heater, and is not limited to either.

[0117] This application also provides a clothes dryer, such as... Figure 10 and Figure 11 As shown, the device includes a housing 20, a clothes drying device as described in any of the above embodiments, and a clothes hanging component 30. The housing 20 has a drying space; the clothes drying device is disposed in the lower part of the drying space; and the clothes hanging component 30 is disposed in the drying space and located above the clothes drying device.

[0118] In this embodiment, the clothes drying device is located in the lower part of the drying space; the clothes hanging piece 30 is located in the drying space and above the clothes drying device, so that when clothes need to be dried, the clothes to be dried can be hung on the clothes hanging piece, and then the clothes drying device can be turned on. Hot air can flow out more evenly from the air outlet 1b of the clothes drying device and blow towards the clothes located above the clothes drying device, so that the clothes can be dried faster and it is less likely that some clothes will not be completely dried or some clothes will be too dry, so that the clothes dryer 100 has a better drying effect.

[0119] Furthermore, the clothes drying device in the dryer 100 is the same as the clothes drying device in each embodiment. Therefore, the dryer 100 can produce the same or similar beneficial effects as the clothes drying devices in the above embodiments, which will not be described in detail here.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
