Description

Clothes dryer cover and clothes dryer TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes dryer, in particular to a clothes dryer cover and clothes dryer. BACKGROUND

[0002] The guide hole of the cover assembly of the existing clothes dryer is uniformly distributed in the shape of a 5mm diameter hole. In the process of raising pets, it is common for clothes to be stained with pet hair. When the clothes dryer dries such clothes, there is a need to remove pet hair. However, it is not practical to completely remove pet hair. The most annoying pet hair is not long hair, but short hair, so the demand for removing short hair is greater. The length of pet hair is between 30mm and 100mm, and there are distortions. Since the diameter of the guide hole of the cover assembly of the clothes dryer is 5mm, the pet hair cannot pass through these holes and can only remain in the drum. Therefore, the guide hole of the cover assembly of the existing clothes dryer does not have a hair removal function. SUMMARY

[0003] In order to overcome the deficiencies in the prior art, the present application provides a clothes dryer cover and clothes dryer, which has the advantages of improving the hair removal efficiency.

[0004] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0005] A clothes dryer cover, comprising: a cover body; and a hair removal cover arranged on the side wall of the cover body close to the drum; the side of the hair removal cover away from the cover body is a windward surface, and a plurality of wind holes are arranged on the windward surface to enable air from the drum to pass through the hair removal cover; at least part of the plurality of wind holes has a first direction and a second direction, has a first width in the first direction, and has a second width in the second direction, the first direction intersects the second direction, and the first width is greater than the second width; the first width of part of the wind holes is greater than the first width of the remaining wind holes.

[0006] By adopting the above technical scheme, the wind hole with a width greater than that in the remaining direction in one direction makes it easier for distorted pet hair to pass through and thus leave the drum, thereby improving the hair removal efficiency. At the same time, since distorted pet hair has various lengths, if the lengths of the wind holes are all consistent, in order to ensure that the longest pet hair can pass through, the lengths of the wind holes must all be theoretically the maximum length, which will make the strength of the windward surface fail to reach the set strength. By setting the wind holes to have multiple different lengths, the requirement for pet hair to pass through is met, and the strength requirement of the hair removal cover is also met.

[0007] Optionally, the wind hole with the largest first width avoids the center of the windward surface.

[0008] By adopting the technical scheme, the through hole in the center of the windward surface affects the strength of the entire windward surface, and the larger the size of the through hole, the greater the effect on the strength of the entire windward surface, so that the longest wind passage avoids the center of the windward surface, which is conducive to the overall strength of the windward surface to a certain extent without affecting the passing of pet hair.

[0009] Optionally, a plurality of other wind passages are arranged between adjacent wind passages with the largest first width.

[0010] By adopting the technical scheme, a plurality of other wind passages are arranged between the longest wind passages, thereby avoiding the concentration of the longest wind passages and the local insufficient strength of the windward surface.

[0011] Optionally, the longest wind passage is uniformly distributed along the center of the windward surface.

[0012] By adopting the technical scheme, the longest wind passage is uniformly distributed along the center of the windward surface, which improves the probability of the longest pet hair passing through the longest wind passage, and when the pet hair touches the windward surface but cannot pass through the smaller wind passage, the pet hair can still move along the windward surface to have a chance to pass through the longest wind passage, thereby greatly improving the hair removal effect.

[0013] Optionally, the first width of the wind passage is between 10-50mm.

[0014] By adopting the technical scheme, the first width of the wind passage is between 10-50mm, so that under the action of air, most of the length of the pet hair will be deformed to pass through the corresponding wind passage, while ensuring the strength of the windward surface.

[0015] Optionally, the wind passage with the first width and the second width is a strip-shaped hole.

[0016] By adopting the technical scheme, the strip-shaped wind passage makes it easier for the twisted pet hair to pass through and thus leave the drum, thereby improving the hair removal efficiency.

[0017] Optionally, the windward surface is an arc surface protruding away from the side of the cover body.

[0018] By adopting the technical scheme, the windward surface is an arc surface protruding away from the side of the cover body, so that under the action of air, the pet hair that does not pass through the windward surface at the first time can more easily move along the arc surface to meet the wind passage with the adjusted length, thereby greatly improving the possibility of the pet hair passing through the wind passage and thus improving the hair removal efficiency.

[0019] Optionally, a cover filter is further included, which is detachably connected to the lint removal cover, and is located at the air outlet side of the air passing hole and used for collecting the pet hair passing through the air passing hole.

[0020] By adopting the above technical solution, the pet hair can be collected by the cover filter, so as to avoid affecting the overall work of the clothes dryer due to the pet hair entering the subsequent working components with the air. In addition, the detachable connection of the cover filter is conducive to subsequent cleaning.

[0021] Optionally, a sealing ring is arranged between the periphery of the cover filter and the lint removal cover.

[0022] By adopting the above technical solution, the sealing ring improves the collection efficiency and reduces the possibility of impurities including pet hair entering the subsequent air duct with the air, so as to avoid affecting the overall work of the clothes dryer in the subsequent working components.

[0023] Optionally, the cover filter comprises a filter frame seat and a wire mesh arranged on the filter frame seat.

[0024] By adopting the above technical solution, the cover filter is designed as a filter frame seat combined with a wire mesh, which improves the overall strength of the cover filter, and the presence of the filter frame seat also increases the installation convenience of the cover filter.

[0025] A clothes dryer comprises the cover.

[0026] By adopting the above technical solution, the lint removal capacity of the clothes dryer is improved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0035] The application will be further described in detail below in combination with Figs. 1-7.

[0036] Example one: a clothes dryer, referring to Fig. 1, comprising a housing, a drum, a cover, a filter, a heat exchange system, a fan and a ventilation system; the fan and the ventilation system are used to circulate air in the drying process, to guide the air heated by the heat exchange system into the drum to dry the clothes, and then to return to the heat exchange system through the cover and the filter for dehumidification and heating; wherein the heat exchange system comprises a condenser, an evaporator and a compressor.

[0037] Referring to Figs. 2-4, the cover comprises a cover body 10 and a lint cover; the lint cover comprises a lint cover body 20; one end of the cover body 10 is hinged to the housing, and the other end is provided with a lock head connected with the housing; the lint cover body 20 is in the shape of a cylinder with one end open; the open end of the lint cover body 20 abuts against the inner surface of the cover body 10 and is fixedly connected by bolts; the side of the lint cover body 20 away from the cover body 10 is a windward surface 201; when the cover is in a closed state, the windward surface 201 of the lint cover body 20 faces the drum; in order for air to enter the lint cover body 20, a plurality of evenly distributed air passing holes 200 are formed on the windward surface 201; in order to facilitate subsequent air flow downward to the filter, the lower end of the side wall of the lint cover body 20 is formed with an air flow hole 202 which is open upward and downward, so that the air flowing through the drum enters from the air passing hole 200 and then flows out from the air flow hole 202.

[0038] In order to facilitate the pet hair to pass through the air holes 200, referring to FIG. 2 and FIG. 3, part of the air holes 200 are waist holes, the waist hole-shaped air holes 200 are easier for the pet hair to pass through than the round hole-shaped air holes 200, of course, all the air holes 200 can be waist holes; while meeting the hair removal requirements, since the windward surface 201 is perpendicular to the air flow direction, a certain strength is needed to meet the normal working requirements, so the length of the air holes 200 cannot be the same, so it is difficult to balance between strength and hair removal efficiency, based on the above considerations, the air holes 200 have multiple different length specifications, that is, multiple longest air holes 200, multiple shortest air holes 200, and multiple air holes 200 with intermediate length values; after multiple tests, the length of the longest air holes 200 is 50 mm, and the length of the shortest air holes 200 is 10 mm, so that the hair removal effect is best. In order to facilitate the pet hair to more easily enter the air holes 200, the side wall of the air holes 200 and the windward surface 201 are smoothly and smoothly transitioned. In other embodiments, the waist hole-shaped air holes 200 can be replaced by strip hole-shaped air holes 200 or flat air holes 200. In fact, in actual production, as long as the air holes 200 have a first direction a and a second direction b in the cross section perpendicular to the depth direction, the first direction a and the second direction b intersect, the first direction a has a first width, and the second direction b has a second width, the first width is greater than the second width, then the waist hole-shaped air holes 200 can be replaced.

[0039] Referring to FIG. 2 and FIG. 3, considering that if one of the longest air holes 200 is arranged at the center of the windward surface 201, the strength of the windward surface 201 will be greatly affected, so it is necessary to avoid arranging the longest air holes 200 at the center of the windward surface 201, of course, the longest air holes 200 are best away from the center of the windward surface 201; in other embodiments, in fact, no air holes 200 can be arranged at the center of the windward surface 201, so that the strength of the windward surface 201 is less affected, of course, considering the hair removal effect, the windward surface 201 can be provided with air holes 200, but the length of the air holes 200 should not be too large.

[0040] Referring to FIG. 2 and FIG. 3, a plurality of air holes 200 with other length specifications are arranged between adjacent longest air holes 200, so that the longest air holes 200 are not too concentrated to cause the local strength of the windward surface 201 to be too low.

[0041] Referring to Figures 2 and 3, considering hair removal efficiency, air passages 200 of the same length can be evenly distributed along the center circumference of the windward surface 201. However, considering the difficulty of setting up the air passage distribution, some of the larger length air passages 200 can be evenly distributed along the center circumference of the windward surface 201, with the remaining lengths distributed among them. The simplest way to distribute the air passages 200 is to ensure that only the longest air passage 200 is evenly distributed along the center circumference of the windward surface 201, with the remaining lengths distributed among them. This way, even if pet hair cannot pass through the air passage 200 immediately, it will have a chance to pass through the longest air passage 200 as it moves along the windward surface 201, thus improving hair removal efficiency.

[0042] In other embodiments, the windward surface 201 is an arc surface that protrudes from the center toward the side away from the body 10 of the cover. In this way, under the action of air, pet hair that does not pass through the windward surface 201 immediately can more easily move along the arc-shaped windward surface 201 and encounter the air passage 200 whose length meets the requirements, thereby greatly increasing the possibility of pet hair passing through the air passage 200 and thus improving the hair removal efficiency.

[0043] The working principle of Example 1 is as follows:

[0044] As the roller rotates and air flows, pet hair adhering to clothing will detach and move towards the windward side 201 of the hair removal cover body 20. If the direction of movement of the pet hair is directly opposite the air passage 200 and the length of the air passage 200 meets the passage requirement, the pet hair will pass through the air passage 200 and detach from the roller, thus achieving the purpose of hair removal. If the direction of movement of the pet hair does not meet the above conditions, it will touch the windward side 201 and eventually be carried away by the clothing, or move along the windward side 201 and eventually pass through the air passage 200 that meets the passage requirement, thus achieving the purpose of hair removal. When pet hair passes through the air passage 200, the length of the air passage 200 does not need to be exactly greater than the size of the pet hair. When the two sizes are close, the pet hair can pass through the air passage 200 under the action of air.

[0045] Example 2: The difference between Example 2 and Example 1 is as follows: Referring to Figures 4-7, in order to prevent pet hair from entering other working parts of the dryer with the air, the cover also includes a cover filter 30 disposed on the hair removal cover body 20; the upper end of the side wall of the hair removal cover body 20 is formed with an upper mounting hole 203 for the cover filter 30 to be inserted from top to bottom; the cover filter 30 is located on the air outlet side of the air passage 200 and is used to collect hair passing through the air passage 200.

[0046] Referring to Figures 6 and 7, the cover filter 30 includes a filter frame seat and a wire mesh. The filter frame seat is integrally injection molded and includes an external support frame 32 and a filter skeleton 33 disposed within the support frame 32. The filter skeleton 33 has several square-shaped filter perforations, which are covered by the wire mesh. To increase the pet hair collection space, the filter skeleton 33 is located at the end of the support frame 32 away from the windward side 201, thus creating a storage cavity of a certain depth inside the support frame 32. The cover filter 30 is designed with a filter frame seat combined with a wire mesh, which improves the overall strength of the cover filter 30. At the same time, the presence of the filter frame seat also increases the ease of installation of the cover filter 30. To facilitate the installation and removal of the filter mesh and subsequent replacement, several recessed snap-fit ​​grooves are provided on one side wall of the filter frame 33. Each filter perforation is surrounded by a snap-fit ​​groove. The cover filter 30 also includes a fixing frame with the same shape as the filter frame 33. Several snap-fit ​​strips that mate with the snap-fit ​​grooves are formed on one side wall of this fixing frame, thus securing the filter mesh within the snap-fit ​​grooves. To increase the stability of the filter mesh installation, the mesh is positioned on the side of the filter frame 33 closer to the windward side 201. This allows airflow to exert a force on the fixing frame, pushing against the mesh and filter frame 33. Compared to the case where the mesh is positioned on the side of the filter frame 33 further away from the windward side 201, the mesh and fixing frame are less likely to detach. This also prevents pet hair from entering the gap between the mesh and the filter frame 33, facilitating the removal of pet hair from the cover filter 30 later.

[0047] Referring to Figures 4-7, in order to facilitate connection with the cover filter 30, the hair removal cover also includes an intermediate connecting frame 40. The intermediate connecting frame 40 is frame-shaped, and all the air vents 200 are located between the intermediate connecting frames 40. The intermediate connecting frame 40 is fixed inside the hair removal cover body 20 by bolts. The bottom of the intermediate connecting frame 40 is formed with a pair of horizontally arranged lower support hooks 42, and the top is formed with a locking block 41. The bottom of the support frame 32 abuts against the pair of lower support hooks 42, and the upper end is movably connected to a buckle plate 31. The buckle plate 31 has a hook part that cooperates with the locking block 41.

[0048] Referring to Figure 7, in order to further improve the connection stability between the intermediate connecting frame 40 and the cover filter 30, a pair of slots 300 are formed at the bottom of the support frame 32 for the lower support hooks 42 to be inserted from bottom to top. In this way, the lower support hooks 42 and the slots 300 can limit the cover filter 30 in the horizontal direction perpendicular to the air inlet direction. With the vertical and horizontal limiting of the buckle plate 31, the buckle block 41, and the pair of lower support hooks 42, the position of the cover filter 30 is more stable, which helps to reduce working noise and improve the sealing effect of both the intermediate connecting frame 40 and the cover filter 30.

[0049] To further improve the sealing between the support frame 32 and the intermediate connecting frame 40, and reduce the possibility of impurities, including pet hair, entering the subsequent air duct with the air, a sealing ring is provided between the four edges of the support frame 32 and the intermediate connecting frame 40. To improve the stability of the sealing ring and prevent it from detaching during the disassembly of the cover filter 30, a sealing mounting groove for installing the sealing ring is formed on the end face of the support frame 32 near the intermediate connecting frame 40, and the sealing ring is embedded in the sealing mounting groove. In other embodiments, although the intermediate connecting frame 40 and the hair removal cover body 20 are connected by bolts, greatly reducing the gap between them, a sealing ring can still be provided between the intermediate connecting frame 40 and the hair removal cover body 20 to further improve the sealing performance. All of the above-mentioned sealing rings can be rubber sealing rings.

[0050] Working principle of Example 2:

[0051] Pet hair passing through the air vent 200 comes into contact with the mesh as air passes through. The air then passes through the mesh while the pet hair is trapped inside the cover filter 30, thus concentrating the pet hair. To clean, simply open the cover completely and press the latch plate 31, disengaging the latch from the latch block 41. This allows the cover filter 30 to be pulled out. Since the pet hair adheres to the mesh, all the pet hair will be removed along with the cover filter 30. After cleaning, simply reinsert the cover filter 30.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
