Description

Technical Field

[0001] The present application relates to the technical field of clothing drying and processing equipment, and in particular to a clothing processing equipment. Background Art

[0002] Currently, clothes drying equipment with a drying function, such as washing machines and clothes dryers, are equipped with a drying system to dry clothes. The drying system mainly consists of a drying air duct, a heating pipe, a fan, etc. When clothes need to be dried, the equipment dries the clothes by blowing hot air generated by the heating pipe.

[0003] However, during the air circulation process, lint will be brought into the heating tube and its fixing structure. The heating tube has a multiple bend structure. During long-term use, lint will accumulate on the heating tube or its fixing structure, which will greatly affect the drying effect and the user experience.

[0004] There are also patents that mention setting a shell on the heating tube, but the shell has a square structure or other structures. Although it effectively prevents the accumulation of lint on the heating tube, a large amount of lint accumulates on the shell.

[0005] In view of this, this application is hereby filed. Summary of the Invention

[0006] The purpose of the present application is to provide a clothing processing device, in which lint is not easily adhered to the drying duct, the drying duct remains unobstructed, and the drying performance is good.

[0007] The basic concept of the technical solution of this application is:

[0008] A clothes processing device, comprising:

[0009] drying chamber;

[0010] Drying air duct, connected to the drying chamber;

[0011] The heating element is arranged in the drying air duct, and the heating element has an overall streamlined structure.

[0012] In the above scheme, the heating element of the clothing processing device is designed as a streamlined structure. During the drying process, the heating element has little obstruction to the drying air, and the lint carried in the air cannot adhere to and accumulate when flowing through the heating element, thereby ensuring the smooth flow of the drying air path and allowing the clothing processing device to maintain good drying performance.

[0013] Preferably, the heating element includes:

[0014] Heating tube;

[0015] The heat conducting part is arranged on the outside of the heating tube and has a streamlined structure.

[0016] In the above scheme, the heating tube maintains the original design. Based on the existing heating tube, this application provides a heat-conducting part on the heating tube. The heat-conducting part has a streamlined structure and is arranged on the outside of the heating tube. The surface area is larger and the heat exchange efficiency is higher.

[0017] Preferably, the heat conducting part includes a heat conducting body extending along the length / width direction of the drying air duct, a heating tube is provided in the heat conducting body, and sharp corners are provided at both ends of the heat conducting body along the extension direction of the drying air duct.

[0018] In the above scheme, the heat-conducting part includes a heat-conducting main body, and a sharp corner portion is provided at the end of the heat-conducting main body, so that the heat-conducting part is streamlined as a whole. The drying air flowing through is dispersed by the sharp corner portion and flows along the outer peripheral surface of the heat-conducting part. During the whole process, the lint cannot stick to the heat-conducting part, thereby ensuring the smooth flow of the drying air path.

[0019] Preferably, the heat-conducting body is a flat structure extending along the length / width direction of the drying air duct, and the upper surface and the lower surface of the two end portions of the flat structure along the extension direction of the drying air duct are inclined and converged toward each other to form sharp corners.

[0020] In the above scheme, in order to ensure that the storage of the entire mechanism does not occupy the internal space of the equipment, the drying duct is designed as a flat structure, the heating element is also set to a flat structure, and the overall structure of the pointed corner is wedge-shaped, and the upper and lower surfaces of the pointed corner can be inclined planes or curved surfaces.

[0021] Preferably, the clothes processing device further includes a heat insulating portion.

[0022] The heat insulating portion is arranged between the heat conducting portion and the inner wall of the drying air duct.

[0023] In this solution, the heat conducting element doesn't come into direct contact with the drying duct. Instead, the two are separated by an insulating element, preventing heat loss and conserving energy. Furthermore, the thickness of the insulating element is equal to the gap between the heating element and the drying duct, preventing air from passing through and preventing lint from accumulating.

[0024] Preferably, the heat insulation part includes two heat insulation parts, which are respectively arranged on both sides of the heat conduction part along the width direction of the drying air duct. The two sides of the heat conduction part are supported on the drying air duct by a heat insulation part respectively, thereby improving the installation stability of the heat conduction part.

[0025] Preferably, support structures are respectively provided on both sides of the heat conducting part in the drying air duct, and the heat conducting part is overlapped on the corresponding support structures through the heat insulating parts on both sides.

[0026] In the above solution, by arranging support structures on both sides of the air duct, it is convenient to support and install the heat insulation part.

[0032] The supporting structure includes a first vertical bending edge bent outward to form a horizontal bending edge, and an upper protruding portion arranged on the horizontal bending edge.

[0033] The two sides of the heat conducting portion are overlapped on the horizontal bending edge through the heat insulating portion.

[0034] In addition, the two sides of the heating element are limitedly installed between the two upper protrusions on both sides of the lower shell through the heat insulation part, and the two upper protrusions on both sides of the lower shell have the function of limiting and fixing the heating element.

[0035] Preferably, both side edges of the bottom of the heat conducting portion are provided with avoidance portions extending upward.

[0036] The heat insulating portion includes a horizontal portion, which is inserted into the avoidance portion and overlaps the horizontal bent edge. In this way, the horizontal portion of the heat insulating portion isolates the heating element from the lower shell, preventing heat from being transferred to the lower shell.

[0037] Preferably, the heat insulating portion includes a vertical portion vertically connected to the horizontal portion.

[0038] The vertical portion is attached to the side surface of the heat-conducting portion and is located between the upper shell and the heat-conducting portion, thereby isolating the heat-conducting portion from the upper shell and preventing heat from being transferred to the upper shell.

[0039] In the above solution, the heat insulation part is set as an L-shaped structure, which effectively isolates the heating element from the bottom shell and the top shell respectively, thereby improving the energy-saving performance of the equipment.

[0040] Preferably, the upper shell includes an upper base plate.

[0041] Second vertical bending edges extending toward the lower bottom plate are provided on both sides of the upper bottom plate.

[0042] An outer protrusion extending outward is provided on the lower edge of the second vertical bending edge.

[0044] The first connecting structure is fixedly connected to the second connecting structure, and the vertical portion is attached to the second vertical bending edge.

[0045] In the above scheme, after the upper shell and the lower shell are buckled together, they are connected and fixed by the first connecting structure and the second connecting structure, and the vertical part is in contact with the second vertical bent edge. Therefore, the second vertical bent edges on both sides of the upper shell have a clamping and fixing effect on the heating element and the insulation parts on both sides.

[0046] Preferably, the first connecting structure and the second connecting structure are mutually snap-fitting structures; or, the first connecting structure includes a first connecting hole provided on the outer protrusion, and the second connecting structure includes a second connecting hole provided on the upper protrusion, and the fastener passes through the first connecting hole and is connected to the second connecting hole.

[0048] Preferably, the heat conducting part is extended along the width direction of the drying air duct, and a pin is protruding from one end of the heat conducting part along the width direction of the drying air duct, and the pin is inserted into the mounting hole.

[0049] In the above solution, the heat conducting part is fastened to the drying air duct by providing a pin shaft.

[0050] Preferably, a sealing ring is provided between the pin shaft and the inner wall of the mounting hole, and a heat insulating portion is provided covering the shaft section of the pin shaft located between the sealing ring and the heat conducting portion.

[0051] In the above solution, a sealing ring is provided on the pin shaft to isolate the drying air duct from the outside world, thus preventing heat loss. Furthermore, a heat insulating portion is provided between the sealing ring and the heat conducting portion to further prevent heat loss, thereby improving the energy-saving performance of the product.

[0097] See also Figures 1-11 As shown, the present application discloses a clothing processing device, in which lint is not easily accumulated inside the drying duct, and the entire device can maintain good drying performance during long-term use.

[0098] The clothing processing device may be a washer-dryer, a clothes dryer, etc., which is not limited here.

[0099] See also Figure 1 As shown, the clothing processing device includes a drying chamber 4, a drying duct 2, and a heating element 1. The drying chamber 4 is used to hold clothing to be processed. The drying duct 2 is connected to the drying chamber 4 at both ends. A fan is provided within the drying duct 2 to circulate the drying air. The heating element 1 is disposed within the drying duct 2 to heat the air flowing through it. When the clothing processing device is in operation, the heating element 1 is turned on to heat, the fan is started, and the air is driven to flow. After being heated by the heating element 1, the flowing air enters the drying chamber 4 through the drying duct 2 to dry the clothing inside.

[0100] In the prior art, the heating element 1 is a heating tube arranged in the drying air duct 2. The heating tube has a multiple-bend structure. During long-term use, the lint on the heating tube will accumulate more and more, thereby affecting the smoothness of the drying air duct, and then affecting the drying effect, causing user complaints.

[0101] The clothing processing device provided in the embodiment of the present application improves the heating element 1 and can solve the above-mentioned technical problems.

[0102] Specifically, the surface of the heating element 1 is smooth and the overall structure is streamlined. In this way, during the drying process, the heating element 1 has little obstruction to the drying air, and the lint carried in the air cannot adhere to and accumulate when passing through the heating element 1, thereby ensuring the smooth flow of the drying air path, so that the clothes processing device maintains good drying performance. During the drying process of the clothes processing device, the circulating drying air path formed is shown in FIG. Figure 1 At the arrow in .

[0103] See also Figure 2 and Figure 3 As shown, the heating element 1 includes a heating tube 11 and a heat conducting portion 12. The heating tube 11 is a structure with multiple bends, and the heat conducting portion 12 is arranged on the outside of the heating tube 11 and has a streamlined structure.

[0104] In this solution, the heating tube 11 can maintain its existing structure without any changes, that is, the heating tube 11 has a structure with multiple bends. Based on the existing heating tube 11, the present application provides a heat conducting portion 12 on the outside of the heating tube 11. The heat conducting portion 12 has a streamlined structure. The heat conducting portion 12 is arranged on the outside of the heating tube, has a larger surface area, and has a higher heat exchange efficiency. By providing the appearance structure of the heat conducting portion 12, the heating element 1 can be streamlined as a whole.

[0105] See also Figure 2 As shown, the heat conducting portion 12 is extended along the length / width direction of the drying air duct 2. In the direction from the upstream to the downstream of the drying air duct 2, the cross-sectional area of ​​the heat conducting portion 12 gradually increases, or in the direction from the upstream to the downstream of the drying air duct 2, the cross-sectional area of ​​the heat conducting portion 12 gradually increases and extends to a certain length and then gradually decreases. Figure 2 In the coordinate system, the X-axis direction in the coordinate system is the length direction or extension direction of the drying air duct, and the Y-axis direction is the width direction of the drying air duct.

[0106] See also Figure 2 and Figure 3 As shown, the heat conducting unit 12 includes a heat conducting body 121 extending along the length and width of the drying duct 2. The heating tube 11 is disposed within the heat conducting body 121. Pointed corners 122 are provided at both ends of the heat conducting body 121 along the direction of extension of the drying duct 2. In this embodiment, the heat conducting unit 12 includes the heat conducting body 121 and the pointed corners 122 at the ends of the heat conducting body 121. This makes the heating element 1 overall streamlined. The drying air flowing through is dispersed by the pointed corners 122 and flows along the outer peripheral surface of the heat conducting unit. Throughout this process, lint cannot adhere to the heat conducting unit, thus ensuring a smooth drying air path.

[0107] Specifically, the heat-conducting body 121 is a flat structure extending along the length and width of the drying duct 2. The upper and lower surfaces of the flat structure at both ends along the drying duct 2 extend in a direction that converges toward each other, forming a sharp corner 122. To ensure that the entire mechanism can be stored without occupying internal space, the drying duct 2 is designed as a flat structure, and the heating element is also configured as a flat structure. The sharp corner is wedge-shaped, and the upper and lower surfaces of the sharp corner 122 can be either inclined planes or curved surfaces.

[0108] In a specific embodiment, the heat conducting part 12 includes a shell having a cavity therein, and the heating tube 11 is disposed in the cavity. This arrangement is simple in structure, and the shell can be assembled on the outside of the heating tube 11.

[0109] In a preferred solution, the heat conducting portion 12 is formed by pouring a heat conducting material onto a heat conducting tube. The heat conducting material is poured onto the heat conducting tube to form a streamlined structure. The heat conducting material is preferably made of metal. For example, the heat conducting material may be aluminum, but is not limited thereto. Aluminum metal wraps the outer surface of all heating tubes and is cast into a streamlined shape to allow air to pass through with minimal resistance. Aluminum metal has good thermal conductivity, which is conducive to heat exchange.

[0110] See also Figure 4 As shown, the clothes treating device further includes a heat insulating portion 3 .

[0111] The heat insulating portion 3 is disposed between the heat conducting portion 12 and the inner wall of the drying air duct 2 .

[0112] The heat conducting portion 12 is not in direct contact with the drying duct 2. Instead, the two are separated by the heat insulating portion 3, thereby preventing heat loss and conserving heat. Furthermore, the thickness of the heat insulating portion 3 is equal to the gap between the heating element 1 and the inner wall of the drying duct 2, ensuring that air cannot pass through and lint cannot accumulate.

[0113] Specifically, the clothes processing device includes two heat insulating parts 3, which are respectively arranged on both sides of the heat conducting part 12 along the width direction of the drying duct 2. Figure 4 In the coordinate system, the X-axis is the length or extension direction of the drying duct, and the Y-axis is the width direction of the drying duct. In this solution, the heat conducting portion 12 is supported on the drying duct 2 by a heat insulating portion 3 on both sides. This improves the installation stability of the heat conducting portion 12 and isolates both sides of the heat conducting portion 12 from the inner wall of the drying duct to prevent heat loss.

[0114] See also Figure 5 As shown, support structures 223 are provided on both sides of the heat conducting portion 12 in the drying duct 2, and the heat conducting portion 12 is respectively overlapped on the corresponding support structures 223 through the heat insulating portions 3 on both sides. In this solution, by providing support structures 223 on both sides of the drying duct 2, it is convenient to support and install the heat insulating portion 3.

[0115] See also Figure 8 As shown, the drying air duct 2 includes an upper shell 21 and a lower shell 22 that are buckled together; see Figure 5 and Figure 6 As shown, support structures 223 are provided on both sides of the lower shell 22 along the width direction.

[0116] The two sides of the heat conducting part 12 are respectively connected to the support structure 223 through the heat insulating part 3. Figure 4 By providing support structures 223 on both sides of the lower shell 22, the support stability of the heat conducting part 12 is improved.

[0117] See also Figure 5 and Figure 6 As shown, the lower housing 22 includes a lower base plate 221;

[0118] The lower bottom plate 221 is provided with first vertical bending edges 222 that bend upwards on both sides;

[0119] The support structure 223 includes a first vertical bending edge 222 bent outward to form a horizontal bending edge 223a, and an upper protrusion 223b provided on the edge of the horizontal bending edge 223a;

[0120] The two sides of the heat conducting portion 12 overlap the horizontal bent edge 223a through the heat insulating portion 3. The horizontal bent edge provides upward support for the heat conducting portion 12. Furthermore, the two sides of the heat conducting portion 12 are positioned between the two upper protrusions 223b on the two sides of the lower housing 22 via the heat insulating portion 3. The two upper protrusions 223b on the two sides of the lower housing 22 also positionally secure the heating element 1. That is, the two sides of the heating element are positioned between the upper protrusions 223b on the two sides of the lower housing 22 via the heat insulating portion 3.

[0121] See also Figure 7 As shown, the edges of both sides of the bottom of the heat conducting portion 12 are provided with upwardly extending avoidance portions 123; Figure 6 As shown, the heat insulating portion 3 includes a horizontal portion 32, which is inserted into the avoidance portion 123 and overlaps the horizontal bent edge 223a. In this way, the horizontal portion 32 of the heat insulating portion 3 isolates the heating element 1 from the lower housing 22, preventing heat from being transferred to the lower housing 22.

[0122] For further information, see Figure 8As shown, the heat insulating portion 3 further includes a vertical portion 31 perpendicularly connected to the horizontal portion 32; the vertical portion 31 is attached to the side of the heat conducting portion 12 and is located between the upper shell 21 and the heat conducting portion 12, thereby isolating the heat conducting portion from the upper shell and preventing heat from being transferred to the upper shell 21. In this application, the heat insulating portion is configured as an L-shaped structure, thereby wrapping and covering the outer side and bottom of the heat conducting portion, effectively isolating the heating element 1 from the bottom shell 22 and the top shell 21, respectively, preventing heat loss and improving the energy-saving performance of the device.

[0123] Continue to see Figure 8 As shown, the upper housing 21 includes an upper base plate 211 .

[0124] Second vertical bent edges 212 extending toward the lower bottom plate 221 are provided on both sides of the upper bottom plate 211 . An outer protrusion 213 extending outward is provided along the lower edge of the second vertical bent edge 212 .

[0125] The outer protrusion 213 is provided with a first connecting structure, and the upper protrusion 223b is provided with a second connecting structure; the first connecting structure and the second connecting structure are connected and fixed, and the vertical portion 31 is affixed to the second vertical bent edge 212. In this solution, after the upper shell 21 and the lower shell 22 are fastened together, they are connected and fixed by the first and second connecting structures, and the vertical portion is affixed to the second vertical bent edge. Therefore, the second vertical bent edges 212 on both sides of the upper shell 21 have the effect of clamping and fixing the heating element 1 and the heat insulating portion 3 on both sides. The vertical portion 31 also isolates the heat conducting portion 12 from the second vertical bent edge 212 to prevent heat loss.

[0126] In which, the first connecting structure and the second connecting structure are mutually snap-fitting structures; or, the first connecting structure includes a first connecting hole arranged on the outer protrusion, and the second connecting structure includes a second connecting hole arranged on the upper protrusion, and the fastener passes through the first connecting hole and is connected to the second connecting hole.

[0127] In the above embodiments, the heating element 1 is supported and mounted on the support structure 223 in the drying duct via the heat insulation portion 3. The following provides another mounting and fixing structure for the heating element 1, which can be implemented independently or simultaneously with the mounting and fixing structure in the above embodiments, which is supported and mounted via the heat insulation portion 3 and the support structure 223, to improve assembly stability.

[0128] For details, see Figure 9-11 As shown, a pin 124 is protruding from the heat conducting portion 12, and a mounting hole 225 is provided on the side wall of the drying duct 2. Preferably, the mounting hole 225 is provided on the lower housing 22, and the pin 124 is inserted and fixed in the mounting hole 225. That is, the heating element 1 is mounted on the lower housing 22 of the drying duct 2.

[0129] In a specific embodiment, the heat conducting portion 12 is extended along the width direction of the drying duct 2. The width direction of the drying duct 2 defined here has been explained above and will not be repeated here. A pin 124 is protruding from one end of the heat conducting portion 12 along the width direction of the drying duct 2. The pin 124 is inserted and installed in the mounting hole 225. In order to prevent heat loss, the pin 124 can be made of a material with poor thermal conductivity. In this solution, by providing the pin 124, the heat conducting portion 12 is fastened to the drying duct 2, and the assembly structure is stable. The pin 124 can be integrally formed with the heat conducting portion 12, and the material can be the same or different. In addition, the pin 124 can also be detachably connected to the heat conducting portion, thereby facilitating disassembly and installation.

[0130] In a preferred embodiment, the clothing processing device includes a plurality of heating elements 1, each of which is provided with a protruding pin 124, and a mounting hole 225 is provided in the drying duct corresponding to each heating element 1. The heating elements are arranged in sequence along the length direction of the drying duct and are arranged parallel to each other. They are all extended along the width direction of the drying duct and are plugged into the corresponding mounting holes 225 through the pin 124. In this solution, the heating efficiency is improved by arranging a plurality of heating elements in sequence on the drying duct. In addition, in order to prevent lint from accumulating between adjacent heating elements 1, the present application can reasonably set the spacing between adjacent heating elements 1, or adjust the height position of each heating element 1 so that each heating element 1 is staggered to prevent multiple heating elements 1 from blocking each other and forming a dead zone in the air duct, thereby causing lint to accumulate in the dead zone in the air duct.

[0131] See also Figure 11 As shown, a sealing ring 5 is provided between the pin 124 and the inner wall of the mounting hole 225, and a heat insulating portion 3 is provided on the shaft section of the pin 124 between the sealing ring 5 and the heat conducting portion 12. In this solution, the sealing ring 5 provided on the pin 124 isolates the drying duct from the outside world, preventing heat loss. At the same time, the heat insulating portion provided between the sealing ring 5 and the heat conducting portion 12 reduces the heat transfer from the heat conducting portion 12 to the drying duct 2, further preventing heat loss and significantly improving the product's energy-saving performance.

[0132] In summary, the heating element of the clothing processing equipment of the present application is designed as a streamlined structure. During the drying process, the heating element has little obstruction to the drying air, and the lint carried in the air cannot adhere to and accumulate when flowing through the heating element, so that the interior of the drying air duct is clean and the unobstructed drying air path is ensured, so that the clothing processing equipment maintains good drying performance.

[0133] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
