Description

TECHNICAL FIELD

[0001] The utility model relates to a clothes drying machine technical field especially a clothes drying machine cover and clothes drying machine. BACKGROUND

[0002] The cover guide hole of the cover assembly of the current clothes drying machine is uniformly distributed in the shape of Phi 5, in the process of pet keeping, it is very common that clothes are stained with pet hair, when the clothes drying machine dries such clothes, there is a need to remove pet hair, but it is impractical to completely remove pet hair, the most annoying pet hair is not long hair, but short hair, so the need to remove short hair is greater, the length of pet hair is different from 30mm to 100mm, and there are distortion and other conditions, because the diameter of the cover guide hole in the cover assembly is 5mm, pet hair cannot pass through these holes, only remaining in the drum, so the cover guide of the cover assembly of the current clothes drying machine does not have the function of removing hair. SUMMARY

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a clothes drying machine cover and clothes drying machine, which has the advantages of improving the hair removal efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A clothes drying machine 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, a plurality of air passing holes are arranged on the windward surface to enable the air of the clothes drying machine to pass through the hair removal cover from the side of the drum, at least part of the cross sections of the plurality of air passing holes have a first direction and a second direction, the first direction has a first width, the second direction has a second width, the first direction intersects the second direction, and the first width is greater than the second width, the first width of part of the air passing holes is greater than the first width of the remaining air passing holes.

[0006] By adopting the above technical scheme, the air passing hole with a width greater than that in the remaining directions in one direction enables the distorted pet hair to more easily pass through, thereby leaving the drum and improving the hair removal efficiency, at the same time, since the distorted pet hair has various different lengths, if the lengths of the air passing holes are consistent, in order to ensure that the longest pet hair can pass through, the lengths of the air passing holes must be theoretically the maximum length, so that the strength of the windward surface will not reach the set strength, setting the air passing holes in multiple different lengths meets the requirement of pet hair passing through and also meets the strength requirement of the hair removal cover.

[0007] Optionally, the air passing hole with the maximum 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 whole windward surface, and the larger the size of the through hole, the greater the effect on the strength of the whole 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, thereby leaving the drum and 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 improving the hair removal efficiency.

[0019] Optionally, the machine cover filter 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 scheme, the pet hair can be collected by the machine cover filter, so that the pet hair does not enter the subsequent working components with the air, and the overall work of the clothes dryer is not affected.

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

[0022] By adopting the above technical scheme, the sealing ring improves the collection efficiency and reduces the possibility that the impurities including the pet hair enter the subsequent air duct with the air, so that the overall work of the clothes dryer is not affected in the subsequent working components.

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

[0024] By adopting the above technical scheme, the machine cover filter is designed as the filter frame seat combined with the wire mesh, so that the overall strength of the machine cover filter is improved, and the installation convenience of the machine cover filter is also increased by the filter frame seat.

[0025] A clothes dryer comprises the machine cover.

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

[0040] The following will be combined with the Figures 1-7 The utility model is further explained in detail.

[0041] Example one: a clothes dryer, refer to Figure 1 , including shell, drum, machine cover, filter, heat exchange system, fan and ventilation system; fan and ventilation system are used for circulating air in the clothes drying process, and the air heated by heat exchange system is introduced into the drum to dry clothes, and then returns to heat exchange system through machine cover and filter to dehumidify and heat; wherein the heat exchange system includes condenser, evaporator and compressor.

[0042] Refer to Figures 2-4 , the machine cover includes machine cover body 10 and hair removal cover; the hair removal cover includes hair removal cover body 20; one end of machine cover body 10 is hinged on the shell, and the other end is provided with lock head and is connected with the shell; the hair removal cover body 20 is in the form of a cylinder with one end open; the open end of the hair removal cover body 20 abuts against the inner side surface of the machine cover body 10 and is fixedly connected by bolts; the side of the hair removal cover body 20 away from the machine cover body 10 is the windward surface 201; when the machine cover is in the closed state, the windward surface 201 of the hair removal cover body 20 is opposite to the drum; in order for air to enter the hair removal 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 reach the filter, the lower end of the side wall of the hair removal cover body 20 is formed with an air flow hole 202 that 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.

[0043] In order to facilitate pet hair through the air passing hole 200, refer to Figure 2 And Figure 3, part of the air hole 200 is a waist hole, the waist hole-shaped air hole 200 is more likely to let the pet hair pass through than the round hole-shaped air hole 200, of course, it can make all the air holes 200 be waist holes; while meeting the requirements of hair removal, since the windward surface 201 is perpendicular to the direction of air flow, a certain strength is needed to meet the requirements of normal work, so the length of the air hole 200 cannot be the same, so it is difficult to balance between strength and hair removal efficiency, based on the above considerations, the air hole 200 has 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 hole 200 is 50mm, and the length of the shortest air hole 200 is 10mm, so the hair removal effect is best. In order to make it easier for pet hair to enter the air hole 200, the side wall of the air hole 200 and the windward surface 201 are smoothly and smoothly transitioned. In other embodiments, the waist hole-shaped air hole 200 can be replaced by a strip-shaped air hole 200 or a flat air hole 200. In fact, in actual production, as long as the air hole 200 has a first direction a and a second direction b in the cross section perpendicular to its 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, which can replace the waist hole-shaped air hole 200.

[0044] Reference Figure 2 and Figure 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 hole 200 at the center of the windward surface 201, of course, the longest air hole 200 is far away from the center of the windward surface 201 is the best; in other embodiments, the center of the windward surface 201 can also not be provided with an air hole 200, which will have less effect on the strength of the windward surface 201, of course, considering the hair removal effect, the windward surface 201 can be provided with an air hole 200, but the length of the air hole 200 should not be too large.

[0045] Reference Figure 2 and Figure 3 , a plurality of air holes 200 with other length specifications are arranged between adjacent longest air holes 200, so that the distribution of the longest air holes 200 is not too concentrated, which can avoid the local strength of the windward surface 201 being too low.

[0046] Reference Figure 2 and Figure 3, considering the efficiency of removing pet hair, the same length specification of the through-air holes 200 can be evenly distributed along the center of the windward surface 201; of course, considering the difficulty of setting the distribution of the through-air holes, several larger length specifications of the through-air holes 200 can be evenly distributed along the center of the windward surface 201, and the remaining length specifications of the through-air holes 200 are distributed therein. Of course, the simplest way to distribute the through-air holes 200 is to ensure that only the longest through-air holes 200 are evenly distributed along the center of the windward surface 201, and the remaining length specifications of the through-air holes 200 are distributed therein, so that even if the pet hair cannot pass through the through-air holes 200 at first, it will have the opportunity to pass through the longest through-air holes 200 during the subsequent movement along the windward surface 201, thereby improving the efficiency of removing pet hair from one angle.

[0047] In other embodiments, the windward surface 201 is an arc surface that is convex towards the side away from the cover body 10, so that under the action of air, pet hair that does not pass through the windward surface 201 at first can more easily move along the arc-shaped windward surface 201 to encounter a through-air hole 200 that meets the length requirement, thereby greatly improving the possibility of pet hair passing through the through-air hole 200 and improving the efficiency of removing pet hair.

[0048] The working principle of the first embodiment is as follows:

[0049] With the rolling of the drum and the flow of air, pet hair adhering to the clothes will be separated and move along the windward surface 201 of the lint removal cover body 20. If the moving direction of the pet hair is directly opposite the through-air hole 200 and the length of the opposite through-air hole 200 meets the passing requirement, the pet hair will pass through the through-air hole 200 to achieve the purpose of removing lint; if the moving direction of the pet hair does not meet the above conditions, it will touch the windward surface 201 and eventually be taken away by the clothes or move along the windward surface 201 and eventually pass through the through-air hole 200 that meets the passing requirement to complete the purpose of removing lint from the drum. When the pet hair passes through the through-air hole 200, the length of the through-air hole 200 does not necessarily have to be greater than the size of the pet hair, and when the two sizes are close, the pet hair can also pass through the through-air hole 200 under the action of air.

[0050] Embodiment two: the difference between embodiment two and embodiment one is that: Figures 4-7 In order to prevent pet hair from entering other working components of the clothes dryer along with the air, the cover further comprises a cover filter 30 arranged on the lint removal cover body 20; the upper end of the side wall of the lint 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 through-air hole 200 and is used to collect the hair passing through the through-air hole 200.

[0051] Reference Figure 6 andFigure 7 The cover filter 30 comprises a filter frame and a wire mesh; the filter frame is integrally injection molded and comprises an external support frame 32 and a filter skeleton 33 arranged in the support frame 32; the filter skeleton 33 is formed with a plurality of square hole-shaped filter perforations, and the wire mesh covers the filter perforations. In order 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 surface 201, so that the inside of the support frame 32 forms a certain depth of the receiving cavity. The cover filter 30 is designed to combine the filter frame with the wire mesh, thereby improving the overall strength of the cover filter 30, and the presence of the filter frame also increases the installation convenience of the cover filter 30. In order to facilitate the disassembly and replacement of the wire mesh, a plurality of sunken clamping grooves can be arranged on one side wall surface of the filter skeleton 33, and the clamping grooves are arranged around each filter perforation. The cover filter 30 further comprises a fixed frame identical in shape to the filter skeleton 33, and a plurality of clamping strips are formed on one side wall surface of the fixed frame and matched with the clamping grooves, so that the wire mesh is clamped in the clamping grooves by the clamping strips. In order to increase the installation stability of the wire mesh, the wire mesh is located on the side of the filter skeleton 33 close to the windward surface 201, so that the air flow provides a force to the fixed frame towards the wire mesh and the filter skeleton 33 during the air flow process. Compared with the case where the wire mesh is located on the side of the filter skeleton 33 away from the windward surface 201, the wire mesh and the fixed frame are less likely to fall off, and the pet hair is less likely to enter the gap between the wire mesh and the filter skeleton 33, which facilitates the subsequent cleaning of the pet hair from the cover filter 30.

[0052] Reference Figures 4-7 In order to facilitate connection with the cover filter 30, the hair removal cover further comprises a middle connecting frame 40, the middle connecting frame 40 is frame-shaped, and all the air passing holes 200 are located between the middle connecting frames 40; the middle connecting frame 40 is fixed in the hair removal cover body 20 by bolts; the bottom of the middle connecting frame 40 is formed with a pair of horizontally arranged lower support hooks 42, and the top is formed with a clamping 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 with a clamping buckle plate 31; the clamping buckle plate 31 has a clamping hook part matched with the clamping block 41.

[0053] Reference Figure 7In order to further improve the connection stability of the intermediate connecting frame 40 and the machine cover filter 30, the bottom of the support frame 32 is formed with a pair of clamping grooves 300 for the lower support hooks 42 to be inserted from below, so that the machine cover filter 30 can be limited in the horizontal direction perpendicular to the air entering direction through the cooperation of the lower support hooks 42 and the clamping grooves 300. In combination with the clamping buckle plate 31, the clamping block 41, the vertical direction of the pair of lower support hooks 42 and the horizontal direction parallel to the air entering direction, the position of the machine cover filter 30 is more stable, which is beneficial to reduce the working noise and improve the sealing effect of both the intermediate connecting frame 40 and the machine cover filter 30.

[0054] In order 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 air, a sealing ring is arranged between the four peripheral edges of the support frame 32 and the intermediate connecting frame 40. In order to improve the stability of the sealing ring and prevent it from coming off during the disassembly of the machine cover filter 30, a sealing installation groove for installing the sealing ring is formed on the end face of the support frame 32 close to the intermediate connecting frame 40, and the sealing ring is embedded in the sealing installation groove. In other embodiments, although the intermediate connecting frame 40 and the hair removal cover body 20 are connected by bolts, which greatly reduces the gap between them, in order to further improve the sealing of both the intermediate connecting frame 40 and the hair removal cover body 20, a sealing ring can be arranged between them. The above-mentioned sealing ring can be a rubber sealing ring.

[0055] Principle of embodiment two:

[0056] The pet hair passing through the air hole 200 is resisted by the wire mesh when the air passes through the wire mesh, so that the pet hair is retained in the machine cover filter 30, so as to concentrate the pet hair. When cleaning is needed, the machine cover filter 30 can be pulled out upward after the machine cover is completely opened and the clamping buckle plate 31 is pressed, so that the clamping hook part of the clamping buckle plate 31 is separated from the clamping block 41. Since the pet hair will be attached to the wire mesh, all the pet hair will be taken out with the machine cover filter 30. After cleaning, the machine cover filter 30 can be inserted back.

[0057] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made in structure, shape and principle according to the present application should be covered within the protection scope of the present application.
