[0061] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the description uses a clothes dryer as an example of a clothing processing device, the clothing processing device of the present application can obviously also be a washing and drying machine, a care machine with steam + drying function, and the like.

[0062] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0063] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0064] Combine the following Figures 1 to 27, taking the clothing processing device of the present application as a clothes dryer as an example, a possible specific implementation method of the present application is elaborated in detail.

[0065] See also Figures 1 to 4 , Fig.10 The clothes dryer includes a housing 1, and a working chamber 2 (for example, an outer drum), a heating module 3 and a fan 4 arranged in the housing 1. The fan 4 is arranged to blow the hot air passing through the heating module 3 into the working chamber 2 to dry the clothes in the working chamber 2. The air may be introduced from the outside for heating, or circulating air heating may be achieved inside the dryer as shown in the figure. The path may be that the fan 4 inhales air from the outer drum, then discharges it to the heating module 3, and then enters the outer drum. The housing 1 is square, and may be a rectangular, square or other structure. The fan 4 is obliquely arranged at the angle between the top surface 11 and the side surface 12 of the square housing. Figure 3 As shown, when the fan 4 is tilted, it can be clearly seen that the highest point on the left side of the fan 4 is roughly the same height as the highest point at the central axis. Compared with the normal vertical setting (only the central axis is the highest), it makes full use of the space at the corners, so that the overall height is reduced, thereby reducing the volume of the clothing processing equipment, reducing the space occupancy of the clothing processing equipment in the room, and improving the user experience.

[0066] Furthermore, the fan 4 is connected to the outer cylinder and inhales air from the outer cylinder, which means that the placement angle of the fan 4 directly affects the opening direction and size of the air outlet of the outer cylinder, which also directly affects the difficulty of demolding and the height of the cost. Therefore, the inclination of the fan 4 must take into account the spatial size and the difficulty of molding the outer cylinder. Based on this, on the basis of being compatible with both, Figure 3 As shown, the angle α between the central axis 41 of the fan and the top surface 11 of the box body ranges from 50° to 85°, further can be 60° to 75°, and further can be 70°. At this time, the angle dimension reaches the best, which can not only make full use of the remaining corner space, but also reasonably reduce the cost of the outer cylinder, killing two birds with one stone.

[0067] The fan 4 is a centrifugal fan 4, which takes in air from the bottom and discharges air from the side. This means that if the conventional air duct is arranged, the air duct should also be arranged along the blowing direction of the fan 4. However, the air duct 5 is usually a regular cross-section shape, such as a rectangular air duct 5. It can fill the space in the box 1 when placed horizontally, but it is difficult to fill the space when placed obliquely, resulting in space waste, causing the product size of the same exhaust volume to become larger in the width direction. Therefore, the present application also designs a set of drainage pipelines, namely the spiral corner channel 8, such as Figure 4 , Fig.10As shown, the wind blown out by the fan 4 is spirally guided, which does not affect the air volume and can slightly change the angle of the wind, so that the rear air duct 5 does not need to be arranged tilted. Preferably, the air duct 5 is parallel to the top surface 11 of the box body. The spiral corner channel 8 is matched with the tilted fan 4 and the parallel air duct 5. The three work together to make the structure of the whole machine more compact and reliable.

[0068] Still further developing the connection structure of the fan 4, the fan 4 is usually connected to the outer cylinder by a hose 7 because vibration is inevitably generated during the operation of the dryer. If a hard connection is used, the vibration will be directly transmitted to the fan 4, making the fan 4 easily deteriorated. Since the distance between the fan 4 and the outer cylinder is often very short, the shorter the distance, the more compact the overall space, which means that the space occupied by the hose 7 itself is very small, and the deformation requirement of the hose 7 is relatively large, and the hose 7 often rubs against the outer cylinder when it is compressed. As the use time increases, the hose 7 is easily damaged and causes air leakage, which affects the drying efficiency of the dryer. Moreover, this air leakage is not easy to detect, which makes users dissatisfied with the performance degradation of the product. Based on the above technical problems, the existing technology usually adopts a more wear-resistant and more expensive new material hose to improve its wear resistance, or adds support ribs in the hose to limit its deformation size. However, replacing the material with better wear resistance will inevitably lead to an increase in the price of the whole machine, and the user will pay more. Adding support ribs will have a counter-effect on shock absorption, reducing the difference between it and the hard pipe, causing the fan 4 to be damaged to a certain extent, so it is not worth the loss. How to solve the above technical problems is a difficulty faced by those skilled in the art.

[0069] Based on the above problems, the present application proposes a new hose 7 to enable the fan 4 of the dryer to match the vibration environment.

[0070] like Figures 5 to 9 As shown, in a possible implementation, the air inlet of the fan 4 of the present application is connected to the working chamber 2 via a hose 7, and an anti-wear structure 71 is provided on the side wall of the hose 7. Figure 8 , Fig. 9 As shown, when the hose 7 is squeezed, the hose 7 is usually collapsed. In this case, the present application directly sets the anti-wear structure 71 on the side wall of the hose 7, preferably on the side wall of the hose 7 close to the working chamber 2, and can be arranged along 1 / 2 of the length of the hose 7, that is, for example Figure 8 In the embodiment, the wear-resistant structure 71 is arranged only on the lower half of the hose 7. More preferably, the wear-resistant structure 71 is arranged along 1 / 4 of the length of the hose 7. Figure 5 , Figure 8 As shown in FIG, the hose 7 is in the shape of a drum with a raised middle portion, and the anti-wear structure 71 is arranged on a portion of the drum-shaped hose 7 close to one side of the working chamber 2 .

[0071] In this way, when vibration occurs, the hose 7 collapses to Figure 5 , Fig. 9 In this state, the side wall of the hose 7 is not in direct contact with the outer cylinder, but rubs the anti-wear structure 71, which makes the rigidity of the whole hose 7 not changed, and can still complete the vibration barrier, avoid damage to the fan 4, and realize the friction protection of the hose 7. Moreover, this design does not require a hose 7 of special material, and the overall production cost is not increased, thereby cleverly solving the problem of insufficient service life and unbalanced product cost of the hose in the prior art.

[0072] The anti-wear structure 71 in the present application can be in various forms. For example, the anti-wear structure 71 can be an anti-wear protrusion, such as a round granular protrusion (not shown in the figure), or a similar Figure 7 The anti-wear protrusions shown are raised cylinders arranged along the circumference of the hose 7. Furthermore, the raised cylinders may be hollow cylinders, and abnormal noise blocking grooves 711 are provided on the side walls of the hollow cylinders. Whenever the raised cylinder collides with the clothing processing device, since the cylinder is hollow, most of the force will be absorbed by the deformation of the cylinder itself, acting as an energy absorption box, and will not be transmitted to the side walls of the hose 7, let alone the fan 4. Compared with a solid raised cylinder, it not only plays an anti-wear role, but also further plays a shock-absorbing role. Furthermore, during actual use, due to the action of the air inside, if the extrusion angle of the raised structure of the hollow structure happens to be directly attached to the opening of the hollow cylinder, please refer to Figure 7 The structure will cause the gas to be squeezed, and each vibration will be accompanied by a popping noise (of course, this problem does not exist if the extrusion angle that blocks the outlet is not just right, which will not be elaborated). In order to further solve this problem, the present application also opens an abnormal sound blocking groove 711 on the side wall of the hollow cylinder. Once the hollow cylinder is completely fitted by the outer tube from the front opening, the air can escape from the abnormal sound blocking groove 711, avoiding the air from being squeezed out instantly after being compressed, thereby fundamentally blocking the generation of abnormal noise.

[0073] The design of the anti-wear structure 71 allows the hose 7 to have both softness and wear resistance without increasing costs or replacing new materials. The anti-wear structure 71 and the hose 7 can be combined in a variety of ways. For example, the hose 7 and the anti-wear structure 71 are integrally formed and made of the same material. It is only necessary to reserve a preset service life of the anti-wear structure 71, such as a 20-year friction life. It is also possible that after the anti-wear structure 71 and the hose 7 are integrally formed, the end of the anti-wear structure 71 is covered with a more anti-wear material jacket, or the anti-wear structure 71 and the hose 7 are designed separately and then connected together, which can be in the form of bonding, etc., to achieve the fusion of the two. Preferably, it is integrally formed, which is easier to manufacture and has lower costs.

[0074] Next, other inventive aspects of the present application will be described along the direction of wind flow.

[0075] Please continue to participate Figures 10 to 13 , the wind blown out from the fan 4 is evenly blown to the filter assembly 6 after being turned through the air duct 5, and then blown to the heating module 3 to achieve heating. In this process, when the wind in the air duct 5 is directly introduced into the filter assembly 6 and the heating module 3, these winds produce a certain balancing effect when blowing to the filter net 62, making the wind entering the heating module 3 become much more uniform. Therefore, there are few further changes in the prior art for this purpose. However, the applicant found that even if the filter assembly 6 can achieve a partial effect of uniform air volume, the uniform state of different filter assemblies 6 is different. In actual use, there is still a problem of uneven air volume distribution, resulting in the thermal energy of the heat exchange assembly not being fully utilized. The product still has the possibility of further improvement. Based on this, how to make the wind more uniform when it is blown out of the air duct 5, that is, before reaching the filter assembly 6, is another technical problem that the present application hopes to solve.

[0076] Based on the above technical problems, the applicant proposed a different air duct structure design, please refer to Figures 10 to 13 In a possible implementation, the fan 4 can blow air to the heating module 3 through the air duct 5, and then enter the working chamber 2 to dry the clothes in the working chamber 2. In the air duct 5, a first guide plate 51 and a second guide plate 52 are arranged along the flow direction of the wind. The distance between the first guide plate 51 and the right wall 54 of the air duct is m, and the distance between the second guide plate 52 and the right wall 54 of the air duct is n, where m>n. Preferably, as shown in the figure, the first guide plate 51 and the second guide plate 52 are arc-shaped guide plates.

[0077] When the air flows in the air duct 5, it needs to be discharged from the left wall 55 of the air duct. The present application provides at least two guide plates. The first guide plate 51 realizes the first wind backflow, and a size m is reserved along the right wall 54 of the air duct for the remaining wind to continue to move along the air duct 5. Then, the second wind backflow is realized at the second guide plate 52. Since m>n, the wind flowing out from m at this time will inevitably be further backflowed by the second guide plate 52, realizing graded backflow, so that the wind blown out of the air duct 5 is evenly backflowed according to the preset air volume.

[0078] Furthermore, the distance between the first guide plate 51 and the left wall 55 of the air duct is p, and the distance between the second guide plate 52 and the left wall 55 of the air duct is q, wherein p<q. Furthermore, the size of the first guide plate 51 is larger than the size of the second guide plate 52, such as Fig.13 As shown, since m>n, if the size of the first guide plate 51 is larger than the size of the second guide plate 52, p<q can also be achieved.

[0079] In order to balance the air volume and compensate for the situation where the front wind volume diversion may be insufficient when m is large, the present application also designs a structure of p<q, which can enable the first guide plate 51 on the front side to guide more air volume close to the right wall 54 of the air duct, thereby achieving a more uniform delivery of the overall air volume of the air duct 5.

[0080] A third guide plate 53 is also provided at the tail portion along the wind flow direction in the air duct 5, and both ends of the third guide plate 53 are respectively connected to the right wall 54 and the left wall 55 of the air duct. The wind leaking from the second guide plate 52 will continue to flow toward the third guide plate 53. Since both sides of the third guide plate 53 are connected to the left wall 55 and the right wall 54 of the air duct, no wind will pass through the third guide plate 53, so that all the wind in the air duct 5 is guided to the filter assembly 6 and the fan 4 through the air outlet of the left wall 55 of the air duct.

[0081] The relative positions of the first guide plate 51 and the second guide plate 52 in the air duct 5 also directly affect the diversion effect of the air duct 5, and thus affect the uniformity of the overall air output. In a possible embodiment, the ratio of the length j of the air duct 5 to the spacing dimension h between the first guide plate 51 and the second guide plate 52 is in the range of 1.5 to 4.5, and more preferably in the range of 2.5 to 3.5, which can achieve the optimal diversion state of the guide plate setting of the present application.

[0082] Next, other inventive aspects of the present application will be described along the direction of wind flow.

[0083] After being diverted, the wind in the air duct 5 begins to blow toward the filter assembly 6. Please refer to Fig.10 , Figures 14 to 18 The present application sets a pull-out filter assembly 6, which has the advantage of being able to clean and replace the filter 62 very conveniently. Compared with other built-in filters, the user operation and cleaning are very simple and convenient. However, during the experimental use, the applicant found that this vertically set pull-out filter 62 has some disadvantages. When there are too many spoils on the filter 62, the spoils on the filter 62 will inevitably fall to the outside of the filter assembly 6, especially the windward side, such as the exhaust port of the slideway and the air duct 5, during the process of pulling out. In the long run, deposition will occur, making the filter assembly 6 difficult to pull out and unable to thoroughly clean the internal impurities. When the filter 62 is set at an angle, its filtering and air outlet effects are not good enough. Therefore, how to solve the above technical problems is what the applicant needs to focus on.

[0084] Based on the above technical problems, the applicant proposed a new filter assembly 6, which includes a filter bracket 61 and a filter 62. The filter bracket 61 is provided with a mounting groove 611 on the windward side close to the air duct 5. The depth of the mounting groove 611 is greater than the thickness of the filter 62, so that after the filter 62 is installed, the mounting groove 611 still has a dust receiving surface 6111 on the windward side. Fig.14 , 15 , 17, 18, wherein in order to more accurately show the structure of the filter support 61, Fig.14 No filter 62 is installed. Fig.15 The filter screen 62 is schematically shown, the depth of the installation groove 611 is a, and the thickness of the filter screen 62 is b, wherein the size relationship between a and b is a≥2b, further, a≥4b, and further, a≤6b.

[0085] The depth of the installation groove 611 is greater than the thickness of the filter 62, so that after the filter 62 is installed, the preset dust holding surface 6111 can appear. When the filter bracket 61 is pulled out, even if some of the debris on the filter 62 falls off, it can be received by the dust holding surface 6111, thereby preventing it from falling into the machine, thus solving the problem of dust falling during the extraction process from the root. The size of the dust holding surface 6111 also needs to be reasonably selected. If it is too small, it cannot hold dust, and if it is too large, it will take up too much space, resulting in an increase in the size of the machine. Therefore, it is preferably a≥2b, and more preferably 6b≥a≥4b. Fig.15 The structural ratio shown is within the most preferred size range of a=4.2b.

[0086] In order to further improve the dust collection capability, in a possible implementation, Fig.15 As shown, the dust holding surface 6111 is provided with a dust holding groove 61111, which may be V-shaped or arc-shaped. Furthermore, in order to further prevent the movement of dust and lock the dust, in a possible implementation, the dust holding surface 6111 is a corrugated surface or a convex frosted surface.

[0087] Furthermore, in order to support the filter 62 and prevent the filter 62 from being deformed due to the windward state during use, Fig.14 , 15 As shown, a grid support frame 6112 is provided at the bottom of the installation groove 611 , and the filter screen 62 is installed on the grid support frame 6112 to achieve a better support effect, so that the filtering effect of the filter screen 62 is better.

[0088] like Fig.18As shown, the filter assembly 6 also includes a handle 63. The handle 63 of the present application is arranged on the outside of the box 1, so that the filter bracket 61 can be pulled out from the outside of the box 1. In addition, the handle 63 and the box 1 are flush with the zero-embedded design (the zero-embedded design is a design in which the outer surface cannot make the user feel the gap as much as possible). The handle 63 and the box 1 are basically seamless, which requires the structural size control of the handle 63 to be very precise. However, in the actual production process, it is inevitable that the size does not meet the standard. Once the size is too fine, the yield rate will be reduced, and the structural production cost here will increase geometrically, which is not what the applicant wants to see. In addition, even the finished products with high precision that have been strictly screened will have problems. The filter 62 of the dryer of the present application is close to the heating module 3. During long-term use, the filter bracket 61 will inevitably produce some deformation, which will be transmitted to the handle 63 at this time, which will make the handle 63 unable to be pushed into the reserved gap of the box 1, or cause the gap at the handle 63 to become uncontrollable, which is not what the applicant wants to see. Based on the actual production accuracy and the aging and deformation problems of subsequent product use, the applicant proposed a new feasible solution to solve the above technical problems.

[0089] Based on the above technical problems, the present application proposes a new connection method between the filter 62 and the handle 63, in which the handle 63 is set to be able to move with a preset size relative to the filter 62, so that the handle 63 can pull out the filter 62 and adjust its own fixed position. In this way, when the filter bracket 61 is slightly deformed, since there is an adjustment space between the handle 63 and the filter 62, which is a flexible connection, the position of the handle 63 can be adjusted in a targeted manner so that it can always enter Fig.18 There are many implementations of the flexible connection, and several possible implementations are listed below.

[0090] like Figures 14 to 21 As shown, in a possible implementation, a first connecting frame 621 is provided on the filter screen 62, and a second connecting frame 631 is correspondingly provided on the handle 63. A first connecting hole 6211 is provided on the first connecting frame 621, and a first connecting column 6311 is correspondingly provided on the second connecting frame 631. The first connecting column 6311 is inserted into the first connecting hole 6211 and can have a translational movement of a preset size to achieve the connection between the first connecting frame 621 and the second connecting frame 631. Of course, the positions of the holes and the columns can obviously be interchanged, and will not be expanded.

[0091] Furthermore, the first connection hole 6211 is Fig.17 , Fig. 20 The waist hole shown in the figure, the first connecting column 6311 is Fig.16 , Fig.17, Fig. 20 The cylinder, at this time Fig. 20 As shown, after the first connecting column 6311 is inserted into the waist hole, it can have a preset size of translational movement, for example, the preset size is size c, or when there is a gap k between the cylinder and the waist hole, the preset size is size c+2k. In this way, the handle 63 can be rotated at any angle and translated in a preset size.

[0092] In actual use, the applicant does not want the rotation of the flexible connection to be unlimited, because such unlimited will make the handle 63 too loose, and it is easy to rotate excessively so that the handle 63 cannot achieve the preset zero-embedded design. Based on this, the present application also proposes that a second connection hole 6212 is provided on the first connection frame 621, and a second connection column 6312 is correspondingly provided on the second connection frame 631. The second connection column 6312 is inserted into the second connection hole 6212 and can have a preset size of translation and a preset angle of rotation, and cannot rotate a full circle. Of course, the positions of the hole and the column can obviously be interchanged, and no further expansion will be given.

[0093] Specifically, in order to implement the above solution, the cross-sectional shapes of the second connecting hole 6212 and the second connecting column 6312 are both non-circular, and the cross-sectional size of the second connecting hole 6212 is larger than the cross-sectional size of the second connecting column 6312, so that after the second connecting column 6312 is inserted into the second connecting hole 6212, it can have a translational movement of a preset size and a rotational movement of a preset angle, and cannot rotate a full circle.

[0094] Furthermore, the above-defined solution is explained with a specific embodiment. The second connecting hole 6212 is as follows: Fig.19 , Fig.21 In the scheme shown, the cross-sections of the second connection hole 6212 and the second connection column 6312 are both closed special shapes formed by splicing straight lines and arc lines, and have the same shape, which is a water drop shape, and the cross-sectional size of the second connection hole 6212 is larger than the cross-sectional size of the second connection column 6312, and the interval is d, so that after the second connection column 6312 is inserted into the second connection hole 6212, it can have a preset size of translational movement and a preset angle of rotational movement, and cannot rotate a full circle, wherein the preset size of translational movement is 2d, and the preset angle is the rotation angle between the two based on the interval d. Among them, the type of the first connection hole 6211 / the second connection hole 6212 is not limited, and it can be a through hole or a blind hole.

[0095] In this way, the handle 63 is simultaneously limited by the first connecting hole 6211 / first connecting column 6311 and the second connecting hole 6212 / second connecting column 6312, and can achieve a preset lateral displacement distance of the smallest one between c+2k / 2d (the product design can select appropriate c, k, d according to actual needs), and can achieve rotation at a preset angle based on the interval d, thereby achieving reasonable angle adjustment between the handle 63 and the slot of the shell, without making the handle 63 too loose, achieving multiple goals at one stroke.

[0096] Of course, the above is only a schematic illustration of a possible implementation of the first connection hole 6211 / first connection column 6311 and the second connection hole 6212 / second connection column 6312. Based on the understanding of the above technical solution, those skilled in the art can obviously make reasonable changes, which also belong to the inventive concept of the present application, such as the position exchange and cross-section transformation of the first connection hole 6211 / first connection column 6311 and the second connection hole 6212 / second connection column 6312. Such changes are still within the protection scope of the present application, as shown below:

[0097] The cross section of the first connecting hole 6211 / the first connecting column 6311 can obviously also be Fig. 22 The cross-sections shown are all rectangular structures, and the length direction of the first connection hole 6211 is greater than the length direction of the first connection column 6311, so that after the first connection column 6311 is inserted into the first connection hole 6211, it can have a preset size of translation movement, and it can also achieve a preset size of lateral movement and rotation. Similarly, the cross-section of the second connection hole 6212 / the second connection column 6312 can obviously also be Fig.23 The cross sections shown are all elliptical and have the same shape (here, shape refers to all elliptical shapes, and does not include the same size), and the cross-sectional size of the second connection hole 6212 is larger than the cross-sectional size of the second connection column 6312, so that after the second connection column 6312 is inserted into the second connection hole 6212, it can have a preset size of translation and a preset angle of rotation, and cannot rotate a full circle. Deformations of the above structure are all within the scope of protection of this application.

[0098] After the flexible connection between the handle 63 and the filter bracket 61 is realized, there is another important design point. When the flexible connection between the handle 63 and the filter bracket 61 is completed, the handle 63 has reasonable angle adjustment and lateral adjustment. However, it lacks certain fixing means, and the handle 63 may still be loose. In order to take into account the problem of the adjustability and looseness of the handle 63, as shown in FIG. Fig.18As shown, the present application further provides a flexible gasket 633 between the first connecting frame 621 and the second connecting frame 631. The elasticity of the flexible gasket 633 will ensure that the handle 63 is always in a stable state. When the handle 63 must be adjusted due to deformation of the filter bracket 61, it can also overcome the elasticity of the flexible gasket 633 to achieve small-angle rotation and small-size translation, and will not generate noise due to the gap between the handle 63 and the filter bracket 61. It kills two birds with one stone and is also one of the important technical means for the flexibly connecting the handle 63 and the filter bracket 61.

[0099] In addition, a clamping strip 6213 is provided on the first connecting frame 621, and correspondingly, a clamping rib 632 matching the clamping strip 6213 is provided on the second connecting frame 631. After the filter 62 is connected to the handle 63, the clamping rib 632 can abut against the clamping strip 6213. When realizing the rotation of the handle 63, the user needs to manually twist it, and then an abutting force can be applied after the twisting is completed, which helps the handle 63 to be fixed in the twisted position without rebounding. It is also one of the important technical means for the flexible connection between the handle 63 and the filter bracket 61.

[0100] Such a setting ultimately achieves a flexible connection between the handle 63 and the filter bracket 61, and can ensure the zero-embedded design of the outer wall of the dryer, and reduces the precision requirements for product generation, thereby correspondingly reducing production costs and improving the adaptability of the handle 63. Compared with conventional connection methods, the solution of the present application has achieved significant technical effects.

[0101] like Fig.18 , Fig.24 As shown, when the user takes out the filter 62 for cleaning, a gap will inevitably appear. In order to improve energy efficiency, the present application also mentioned in the above scheme that the heating module 3 is close to the filter 62. Once children and others put their hands into it out of curiosity, it is very likely to cause burns. This risk is not what the applicant wants to see. Based on the above technical problems, the applicant continues to optimize and improve the technical solution of this application.

[0102] like Fig.24 As shown, in order to avoid the problem of scalding caused by deep penetration of the hand, the present application further provides an isolation baffle 10 between the filter assembly 6 and the heating module 3. Furthermore, the isolation baffle 10 is provided on a side close to the pull-out entrance of the filter bracket 61, and a plurality of isolation baffles 10 are provided, and the plurality of isolation baffles 10 are arranged side by side, and the arrangement direction of the plurality of isolation baffles 10 is parallel to the pull-out direction of the filter bracket 61.

[0103] With such a design, even if someone puts their hand in by mistake, it can physically prevent fingers and other parts from contacting the heating module 3, thus fundamentally eliminating the possibility of the above-mentioned danger.

[0104] The heating module 3 of the present application is preferably a PTC heating module (Positive Temperature Coefficient Heater). When cleaning and repairing it, Figure 4 As shown, the entire cover plate 31 needs to be removed. However, the entire cover plate 31 also covers the heating module 3, the filter assembly 6, the air duct 5 and other related structures not mentioned, and the coverage is relatively wide. Since its removal also involves the above-mentioned structures, more positions need to be paid attention to, and other structures are easily damaged. In order to avoid this situation, reduce after-sales difficulties, and reduce the occurrence of after-sales maintenance accidents, the present application also opens an inspection port 32 on the cover plate 31. The inspection port 32 is configured to match the heating module 3, and is preferably arranged on the upper part of the heating module 3. In this way, when the maintenance personnel want to repair the PTC, there is no need to remove the entire cover plate 31. During the maintenance process, only the inspection port 32 is used to work, which reduces the impact on other structural parts. Preferably, the fixing method of the cover plate 31 and the air duct 5 is screw fixing, and the fixing method of the inspection port 32 and the cover plate 31 is snap-fit ​​fixing. The above fixing method can make the cover plate 31, which is not often disassembled, fixed more securely and reliably, and the inspection opening 32 is more convenient for maintenance, and workers can disassemble it without other tools.

[0105] The invention of the present application is introduced above in combination with the direction of wind flow. During the use of the dryer, in order to determine the degree of drying of clothes, a detection element for determining the degree of drying of clothes is usually provided. The detection element in the prior art (not shown in the figure) usually adopts a conventional columnar sensor, which is arranged inside the outer drum. However, this design method has disadvantages. The detection accuracy is often not high enough due to obstruction, etc., which in turn affects the overall working progress judgment of the dryer. In order to solve the above technical problems, the applicant has proposed a new technical solution.

[0106] The applicant creatively designed and used an arc-shaped annular detection element 91, such as Fig.25 As shown, the arc-shaped structure fits the structure of the observation window 9, and the overall fit is high. It occupies the corner arc position and does not affect the normal observation of the user. In addition, the observation window 9 is the viewing angle for direct observation by the user and is also the best viewing angle. It has no relevant obstructions, thereby improving the accuracy of judging the degree of dryness.

[0107] Specifically, the installation position of the detection element 91 of the special structure of the present application also has multiple options, such as Fig.26 , Fig. 27 As shown, the observation window 9 has an inwardly convex boss 92, and the detection element 91 can be arranged on the side of the boss 92, as shown in FIG. Fig. 27As shown, of course, it can also be set on the convex surface of the boss 92 and coincide with the edge of the convex surface, such as Fig.26 , 27 The above two solutions do not affect the user's field of vision, and enable the detection element 91 to achieve the best detection effect. The arc structure of the detection element 91, together with the lead of the detection element 91, also creates a smiley face shape, so that the detection element 91 is harmoniously set with the appearance of the dryer, not abrupt, and improves the appearance of the product.

[0108] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the utility model, and is not intended to limit the protection scope of the utility model. Without departing from the principle of the utility model, those skilled in the art can adjust the above-mentioned structure so that the utility model can be applied to more specific application scenarios.

[0109] For example, in an alternative embodiment, the heating module 3 can obviously also be other types of heating forms, such as electric heating wire heating, etc., as long as it can provide heat for heating the air, these do not deviate from the principles of the present invention, and therefore will fall within the scope of protection of the present invention.

[0110] Those skilled in the art can understand that the above-mentioned clothes processing device also includes some other well-known structures, such as a processor, a controller, a memory, etc., wherein the memory includes but is not limited to a random access memory, a flash memory, a read-only memory, a programmable read-only memory, a volatile memory, a non-volatile memory, a serial memory, a parallel memory or a register, etc., and the processor includes but is not limited to a CPLD / FPGA, a DSP, an ARM processor, a MIPS processor, etc. In order to unnecessarily obscure the embodiments disclosed in the present application, these well-known structures are not shown in the drawings.

[0111] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments.
