[0038] With the improvement of living quality, clothes dryers are becoming more and more common in daily life. The instability of the condensation efficiency of existing clothes dryers seriously affects the energy efficiency of the clothes dryers, and thus improving the condensation efficiency of the clothes dryers and reducing the leakage of hot and humid air become the bottleneck for improving the quality of the clothes dryers.

[0039] A clothes dryer generally comprises a drum, a front support, a rear support plate, a rear cover, a heat exchanger air duct, a door, a sealing strip, and a drum front flange. During actual use of the clothes dryer, the circulating air with high temperature and high humidity is heated into air with high temperature and low humidity after losing moisture through the heat exchanger air duct, enters the drum through the rear cover 4, absorbs moisture in the clothes, and then enters the heat exchanger through the front support, thereby completing the dehumidification process.

[0040] During the dehumidification process, the drum and the front support are sealed by the sealing strip. During this process, due to the large static pressure in the drum and the air permeability of the sealing strip itself, part of the water vapor will run out of the circulating air duct through the sealing strip, affecting the condensation efficiency and user experience.

[0041] Based on this, the present application hopes to provide a solution to the above technical problems, the details of which will be described in the subsequent embodiments.

[0042] The present application discloses a sealing structure, please refer toFigure 1 、 Figure 2 and Figure 5 , Figure 1 is a first perspective view of a sealing structure provided by the present application, Figure 2 is Figure 1 is a local enlarged view of A in FIG. Figure 5 is an assembly structure schematic view of a sealing structure provided by the present application. The sealing structure in the embodiment of the present application is applied to a clothes dryer. It should be understood that the present application does not limit the model of the clothes dryer. Specifically, the sealing structure comprises a front support 100, a sealing strip 200 and a front flange 300 of a drum; wherein the front support 100 is provided with a mounting portion 110, the mounting portion 110 is provided with a mounting groove 111 inside, the sealing strip 200 is arranged in the mounting groove 111, and optionally, the sealing strip 200 is bonded in the mounting groove 111; the front flange 300 of the drum is adaptively connected with the mounting portion 110 and covers the top of the sealing strip 200.

[0043] The working principle of the sealing structure provided by the present embodiment is as follows:

[0044] In actual use, the side of the front flange 300 of the drum away from the front support 100 is used to be connected (for example, riveted) with a drum (not shown in the figure). The present application accommodates the sealing strip 200 by providing the mounting portion 110 on the front support 100 and providing the mounting groove 111 inside the mounting portion 110, and then adaptively connects the front flange 300 of the drum on the mounting portion 110, so that the mounting portion 110 and the front flange 300 of the drum form a fit, and the front flange 300 of the drum also forms a certain pressure on the sealing strip, which can press the sealing strip 200 (so that the sealing strip 200 is more compact, reducing its air permeability). When the drum drives the front flange 300 of the drum to rotate, the front flange 300 of the drum rotates around the mounting portion 110, and the part of the front flange in contact with the sealing strip 200 also rotates while pressing the sealing strip 200, so that the fit of the mounting portion 110 and the front flange 300 of the drum and the contact between the front flange 300 of the drum and the sealing strip can effectively block the water vapor in the drum from leaking from the front support 100. The water vapor in the drum refers to high-temperature and low-humidity air, which enters the drum to absorb the moisture of the clothes in the drum.

[0045] The sealing structure provided by the present embodiment has at least the following beneficial effects:

[0046] Guarantee the amount of water vapor in the drum, reduce the amount of water vapor discharged from the drum, stabilize the condensation efficiency of the clothes dryer, and greatly improve the condensation efficiency of the clothes dryer compared with the existing clothes dryer.

[0047] In one embodiment of the present application, the material of the front support 100 is plastic, which can be formed by injection molding. The front support 100 is hollow, which can reduce its own weight.

[0048] In one embodiment of the present application, please refer to Figure 3 , Figure 3 The second perspective view of the sealing structure provided by the present application. The front support 100 is provided with a plurality of connecting columns 120 on the side away from the drum front flange 300. The connecting columns 120 are provided with threaded holes. The front support 100 can be connected with other components through the connecting columns 120.

[0049] In one embodiment of the present application, the front support is also provided with rolling wheels 130. A plurality of rolling wheels 130 are oppositely distributed on the outside of the mounting portion 110. The plurality of rolling wheels 130 are rolling connected with the drum front flange 300.

[0050] In actual use, the number of rolling wheels 130 is two. The two rolling wheels 130 are symmetrically distributed on the outside of the mounting portion 110. The two rolling wheels 130 are in a movable state. The drum front flange 300 is located between the two rolling wheels 130 and is rolling connected with the two rolling wheels 130. When the drum rotates with the drum front flange 300, the drum front flange 300 rotates around the mounting portion 110 through the two rolling wheels 130. At the same time, the part of the drum front flange in contact with the sealing strip 200 also rotates while pressing the sealing strip 200.

[0051] In one embodiment of the present application, please continue to refer to Figure 4 , Figure 4 The structural diagram of the drum front flange in the sealing structure provided by the present application. The mounting portion 110 is protrudingly arranged on the front support 100. The drum front flange 300 is in a circular ring shape. Part of the drum front flange 300 is arranged on the top of the mounting portion 110.

[0052] The side of the drum front flange 300 away from the front support 100 is provided with a matching groove 301. The matching groove 301 is used for connecting with the drum. Optionally, the matching groove 301 is an arc-shaped groove. It should be understood that the matching groove 301 is mainly used for connecting with the drum. Therefore, only an example is given for the shape. In actual use, adaptive changes should be made according to the specific shape of the drum.

[0053] In one embodiment of the present application, please refer to Figure 3 and Figure 4The first clamping edge 310 and the second clamping edge 320 are both annular, the first clamping edge 310 is located at the outer edge of the drum front flange 300, the second clamping edge 320 is located at the inner edge of the drum front flange 300, and the diameter of the first clamping edge 310 is greater than the diameter of the second clamping edge 320; the first clamping edge 310 is arranged at the top of the mounting portion 110, and the main body portion of the drum front flange 300 covers the top of the mounting portion 110; and the second clamping edge 320 is arranged in the mounting groove 111 and located above the sealing strip 200.

[0054] That is, when the drum is connected to the side of the front support 100 away from the drum front flange 300, because the side of the drum front flange 300 facing the front support 100 is matched with the mounting portion 110 through the first clamping edge 310 and the second clamping edge 320, and the second clamping edge 320 presses the sealing strip 200, the local resistance of water vapor leakage in the drum is increased, thereby reducing the amount of water vapor discharged from the drum.

[0055] In an embodiment of the present application, referring to Figure 1 and Figure 2 , the mounting portion 110 is provided with a fitting groove 112 located above the mounting groove 111; the drum front flange 300 is provided with a positioning portion 302 on the side facing the mounting portion 110, the shape of the positioning portion 302 is matched with the shape of the fitting groove 112, and the positioning portion 302 is located between the first clamping edge 310 and the second clamping edge 320 and matched with the fitting groove 112.

[0056] Specifically, on the basis of the above embodiment, in order to further ensure the stability between the drum front flange 300 and the mounting portion 110, the fitting groove 112 is arranged in the mounting portion 110, and the positioning portion 302 is arranged on the drum front flange 300, so that the stability of the drum front flange 300 can be ensured and the drum front flange 300 cannot be easily moved when the drum front flange 300 is assembled with the mounting portion 110.

[0057] In addition, because of the shape characteristics of the fitting groove 112 and the positioning portion 302, the two are matched and connected, the drum front flange 300 can be quickly positioned, the two can be quickly assembled, and the assembly efficiency can be greatly improved.

[0058] In an embodiment of the present application, referring to Figure 2The fitting groove 112 is in a concave arc shape, and the positioning part 302 is in a convex arc shape. It can be understood that the fitting groove 112 and the positioning part 302 can be quickly assembled by being provided in an arc shape. Of course, the shape of the fitting groove 112 and the positioning part 302 is only an example, and in actual use, it should be changed according to specific needs.

[0059] It is worth mentioning that the height of the vertex of the positioning part 302 does not exceed the height of the vertex of the first clamping edge 310 and the second clamping edge 320. The purpose of this setting is that the height of the vertex of the positioning part 302 cannot be set too large, otherwise it will affect the contact of the first clamping edge 310 and the second clamping edge 320 with the mounting part 110.

[0060] In an embodiment of the present application, please continue to refer to Figure 2 The mounting part 110 comprises a connecting wall, a first mounting wall 102, a second mounting wall 103 and a third mounting wall 104. The connecting wall is arranged on the front support 100 and mainly provides a supporting function. Optionally, the connecting wall is integrally formed with the front support 100. The first mounting wall 102 is arranged on the connecting wall and protrudes from the connecting wall. The second mounting wall 103 is arranged on the connecting wall and is located outside the first mounting wall 102, and surrounds the first mounting wall 102 to form the mounting groove 111. Optionally, the width of the mounting groove 111 is greater than the width of the sealing strip 200, and the depth of the mounting groove 111 is greater than the thickness of the sealing strip 200, so that the sealing strip 200 cannot move after being installed and is always in the mounting groove 111. The third mounting wall 104 is arranged on the connecting wall and is clamped with the first clamping edge 310. The third mounting wall 104 is located outside the second mounting wall 103 and surrounds the second mounting wall 103 to form the fitting groove 112.

[0061] In actual use, the first clamping edge 310 on the front flange 300 of the roller is arranged on the third mounting wall 104, the second clamping edge 320 on the front flange 300 of the roller is arranged in the mounting groove 111 and is in contact with the second mounting wall 103, and the positioning part 302 on the front flange 300 of the roller is connected with the fitting groove 112, so that the mounting part 110 and the front flange 300 of the roller are matched. When the roller rotates with the front flange 300 of the roller, the front flange 300 of the roller rotates around the mounting part 110 through the two rolling wheels 130, and the part of the front flange 300 of the roller in contact with the sealing strip 200 also rotates while pressing the sealing strip 200. Therefore, the cooperation of the mounting part 110 and the front flange 300 of the roller and the contact between the front flange 300 of the roller and the sealing strip 200 can effectively prevent water vapor in the roller from leaking from the front support 100.

[0062] The first clamping edge 310 and the second clamping edge 320 are both provided with a curled edge (not shown in the figure). The curled edge is provided on the first clamping edge 310 and the second clamping edge 320 to enhance the edge strength of the first clamping edge 310 and the second clamping edge 320, so that the first clamping edge 310 and the third mounting wall 104 are not easily damaged when cooperating, and the second clamping edge 320 and the second mounting wall 103 are not easily damaged when cooperating.

[0063] In an embodiment of the present application, please continue to refer to Figure 4 The height of the third mounting wall 104 is greater than the height of the first mounting wall 102 and the height of the second mounting wall 103. The third mounting wall 104 is in an arc shape. The height of the first mounting wall 102 and the height of the second mounting wall 103 are greater than the height of the sealing strip 200, so as to form a mounting groove 111 with a deeper depth, which can adapt to sealing strips 200 with different thicknesses. Alternatively, the height of the first mounting wall 102 is the same as the height of the second mounting wall 103.

[0064] In an embodiment of the present application, please continue to refer to Figure 1 The first mounting wall 102, the second mounting wall 103 and the third mounting wall 104 are all in a circular ring shape, and the centers of the first mounting wall 102, the second mounting wall 103 and the third mounting wall 104 are located at the same point, so as to facilitate the production and manufacture of the first mounting wall 102, the second mounting wall 103 and the third mounting wall 104.

[0065] In an embodiment of the present application, the material of the sealing strip 200 is sponge. The sponge sealing product has small density, excellent sealing performance, buffering performance and elasticity, and can better realize the sealing function. Of course, the material of the sealing strip 200 is only an example, and should be changed according to specific needs in actual use.

[0066] The working principle of the above sealing structure will be described in detail below by taking a specific use scenario as an example:

[0067] When the drum is installed with the drum front flange 300 away from the side of the front support 100, the next step is to set the first clamping edge 310 on the drum front flange 300 on the third mounting wall 104, set the second clamping edge 320 on the drum front flange 300 in the mounting groove 111 and in contact with the second mounting wall 103, and set the positioning part 302 on the drum front flange 300 in adaptive connection with the abutting groove 112, so that a fit is formed between the entire mounting part 110 and the drum front flange 300. When the drum is working, the drum drives the drum front flange 300 to rotate, and the drum front flange 300 rotates around the mounting part 110, and the part of the drum front flange in contact with the sealing strip 200 also rotates while pressing the sealing strip 200. Therefore, through the fit between the mounting part 110 and the drum front flange 300 and the contact between the drum front flange 300 and the sealing strip, the leakage of water vapor in the drum from the front support 100 can be effectively blocked.

[0068] Embodiment two:

[0069] The application also provides a clothes dryer, which comprises a drum and the sealing structure described above; wherein the drum is connected with the drum front flange 300 through the fit groove 301. It should be understood that the clothes dryer of course also comprises other existing structures, such as a rear support plate, a rear cover, a heat exchanger air duct, a door and the like. The application does not limit the specific model or type of the other existing structures of the clothes dryer, and therefore will not be introduced here.

[0070] In summary, the application provides a sealing structure and a clothes dryer, wherein the sealing structure comprises a front support, a sealing strip and a drum front flange; wherein the front support is provided with a mounting part, the mounting part is provided with a mounting groove, and the sealing strip is arranged in the mounting groove; and the drum front flange is adaptively connected with the mounting part and covers the sealing strip. The application sets the mounting part on the front support, sets the mounting groove in the mounting part to accommodate the sealing strip, and then adaptively connects the drum front flange with the mounting part, so that a fit is formed between the mounting part and the drum front flange, and the drum front flange also forms a certain pressure on the sealing strip to press the sealing strip. When the drum drives the drum front flange to rotate, the drum front flange rotates around the mounting part, and the part of the drum front flange in contact with the sealing strip also rotates while pressing the sealing strip. Therefore, through the fit between the mounting part and the drum front flange and the contact between the drum front flange and the sealing strip, the leakage of water vapor in the drum from the front support can be effectively blocked, thereby reducing the amount of water vapor discharged from the drum and greatly improving the condensation efficiency of the clothes dryer.
