DETAILED DESCRIPTION

[0040] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, not all the embodiments.

[0042] Reference Figures 1 to 7 As shown in the figure, the embodiment of the present application provides a door cover device, which comprises a base, a door cover and an energy storage mechanism.

[0043] Wherein, the base is provided with a mounting groove 11; the door cover is provided with a rotating shaft part 32, and the door cover is rotatably connected with the base through the rotating shaft part 32, and the door cover has a door opening position and a door closing position relative to the base; the energy storage mechanism is installed in the mounting groove, and is connected between the base and the door cover; when the door cover rotates towards the door closing position, the energy storage mechanism stores energy and exerts a resistance force away from the door closing position on the door cover; when the door cover rotates towards the door opening position, the energy storage mechanism releases energy and exerts a power towards the door opening position on the door cover.

[0044] When specifically implemented, the energy storage mechanism can be a torsional spring 42 sleeved on the rotating shaft part, when the door cover rotates towards the base to the door closing position, the torsional spring 42 stores energy and exerts a resistance force away from the base on the door cover; when the door cover rotates away from the base to the door opening position, the torsional spring 42 releases energy and exerts a power away from the base on the door cover.

[0045] The above-mentioned base can be selected as a frame structure, and the door cover is a panel structure; the door cover can be rotatably connected to the top side of the base, so that after the door cover rotates away from the base, the door cover can rotate towards the base under the action of its own gravity. The base can be installed on the top of the cabinet of the clothes treatment equipment, the inside of the cabinet is provided with a barrel, the inside of the barrel is provided with a clothes treatment cavity, and the base is provided with a feeding opening communicating with the clothes treatment cavity.

[0046] The door cover is attached to the base to cover the drop opening in the closed position, and has a set angle with the base to expose the drop opening in the open position. The door cover can be set at an angle greater than or equal to 90° with the base in the open position, so that the door cover does not hinder the clothes passing through the drop opening. When the door cover is set on the top side of the base, the door cover will not rotate towards the closed position under its own gravity in the open position.

[0047] The door cover can be set on the top side of the base through the rotating shaft 32 and the energy storage mechanism. The top side of the base is recessed to form a mounting groove 11. A through hole can be provided on one side of the mounting groove 11 as a communication port, so that the rotating shaft 32 can be inserted into the communication port in the width direction of the base.

[0048] A bracket structure can be provided in the mounting groove 11. The bracket structure is provided with a movable hole, and the rotating shaft 32 is movably inserted into the movable hole of the bracket structure, so that the door cover can rotate relative to the base with the rotating shaft 32 as the axis.

[0049] One side of the door cover can be provided with a protrusion, and the rotating shaft 32 is provided on the protrusion. When the door cover is set on the top side of the base, the rotating shaft 32 can be set in the horizontal direction, so that the door cover can rotate towards the direction of approaching or moving away from the base with the rotating shaft 32 as the axis.

[0050] Of course, one side of the door cover can also be recessed to form a notch. The notch has two opposite inner walls, and the rotating shaft 32 is formed on at least one of the two inner walls. The base is set in the notch, and the rotating shaft 32 is connected with the base to rotate. Thus, after the rotating shaft 32 is connected with the base to rotate, the door cover can rotate towards the direction of approaching or moving away from the base with the rotating shaft 32 as the axis.

[0051] The energy storage mechanism can be a torsion spring 42. The torsion spring 42 is sleeved on the rotating shaft 32, and the two ends of the torsion spring 42 are connected with the inner wall of the mounting groove 11 and the rotating shaft 32, respectively. When the door cover rotates towards the base to drive the rotating shaft 32 to rotate, one end of the torsion spring 42 is fixed, and the other end rotates with the rotating shaft 32, so that the torsion spring 42 is elastically deformed to store energy. Of course, the energy storage mechanism can also be a metal sheet with elasticity. One end of the metal sheet is connected with the groove bottom of the mounting groove, and the other end is connected with the door cover. During the process of the door cover rotating towards the base to the closed position, the metal sheet is gradually bent to produce elastic deformation, so that the metal sheet exerts a resistance force on the door cover in the direction away from the closed position. When the door cover rotates towards the open position, the elastic force of the metal sheet is exerted on the door cover to assist the rotation of the door cover towards the open position.

[0052] When the door cover rotates from the open door position to the closed door position, the energy storage mechanism stores energy and exerts resistance on the door cover in a direction away from the base, slowing the speed of the door cover rotating to the closed door position, so as to avoid the door cover colliding with the base and making noise and hurting the user. When the door cover rotates from the open door position to the closed door position, the energy storage mechanism releases energy and exerts assistance on the door cover in a direction away from the base, so that the user can drive the door cover to rotate to the open door position by exerting a smaller force on the door cover, facilitating the user to open the door cover.

[0053] In use, the door cover device provided by the embodiment of the present application is specifically used, the shaft part 32 is rotationally connected with the base, the energy storage mechanism is installed in the installation groove 11 and connected between the base and the door cover. When the door cover rotates to the closed door position, the energy storage mechanism stores energy and exerts resistance on the door cover in a direction away from the base, slowing the speed of the door cover rotating to the closed door position, so as to avoid the door cover colliding with the base and making noise and hurting the user. When the user opens the door cover, the user exerts a force on the door cover in a direction away from the base, so as to drive the door cover to rotate to the open door position. At this time, the energy storage mechanism releases energy and exerts assistance on the door cover in a direction away from the base, reducing the force exerted by the user on the door cover, so that the user can drive the door cover to rotate to the open door position by exerting a smaller force on the door cover, facilitating the user to open the door cover.

[0054] The door cover device provided by the embodiment of the present application includes a base, a door cover and an energy storage mechanism. The base is provided with an installation groove 11. The door cover is provided with a shaft part 32, and the door cover is rotationally connected with the base through the shaft part 32 and has an open door position and a closed door position relative to the base. The energy storage mechanism is installed in the installation groove 11 and connected between the base and the door cover. When the door cover rotates to the closed door position, the energy storage mechanism stores energy and exerts resistance on the door cover in a direction away from the closed door position, so as to slow the speed of the door cover rotating to the closed door position and avoid the door cover colliding with the base and making noise and hurting the user. When the door cover rotates to the open door position, the energy storage mechanism releases energy and exerts assistance on the door cover in a direction away from the closed door position, so that the user can drive the door cover to rotate to the open door position by exerting a smaller force on the door cover. The energy storage mechanism is arranged in the installation groove 11 of the base. On the one hand, the arrangement of the energy storage mechanism does not affect the arrangement of control panels and other electrical devices above the installation groove 11, thereby leaving more space for the installation of the control panels and other electrical devices on the base. Compared with arranging the energy storage mechanism on the door cover, arranging the energy storage mechanism on the door cover occupies more horizontal space, thereby affecting the space for arranging the control panels and other electrical devices on the base. On the other hand, compared with arranging the energy storage mechanism on the door cover, the energy storage mechanism is avoided from being additionally covered by a decorative cover or the like on the door cover, so that the structure of the door cover is simplified, the door cover is avoided from being provided with more parts and being provided with a slot, the structure of the door cover is simplified, the door cover only needs to be rotationally connected with the base through the shaft part 32 to complete the assembly, and the assembly efficiency is improved.

[0055] Referring toFigures 1 to 4 As shown in some embodiments, one side of the door cover is provided with a connecting portion 23, the connecting portion 23 is located at one side of the mounting groove 11, the groove wall of the mounting groove 11 is provided with a communication port, the rotating shaft portion 32 is connected to one side of the connecting portion 23, and the rotating shaft portion 32 extends into the mounting groove 11 through the communication port and is rotationally connected with the base. In this way, the connecting portion 23 can serve as the basic structure of the rotating shaft portion 32, and the connecting portion 23 is provided on the door cover, so that after the rotating shaft portion 32 is rotationally connected with the base, the door cover and the base can have a certain distance through the connecting portion 23, avoiding the edge of the door cover interfering with the base when the door cover rotates relative to the base.

[0056] The mounting groove 11 described above can be arranged at the edge of the base along the width direction of the base, the groove wall of the mounting groove 11 along the width direction of the base is provided with a communication port, and a support can be arranged in the mounting groove 11, and the rotating shaft portion 32 extends into the mounting groove 11 through the communication port, so that the rotating shaft portion 32 can be rotationally connected with the support.

[0057] The side edge of the door cover can be provided with a protruding block structure as the connecting portion 23, the connecting portion 23 is arranged at one side of the mounting groove 11 along the width direction of the base, and the rotating shaft portion 32 is connected to the side of the connecting portion 23 facing the mounting groove 11 along the width direction of the base, so that the rotating shaft portion 32 can enter the mounting groove 11 through the communication port.

[0058] Referring to Figures 1 to 4 As shown, the base is provided with a receiving groove 12, the receiving groove 12 is arranged adjacent to the mounting groove 11 and communicates with the mounting groove 11 through the communication port, and the receiving groove 12 is used to accommodate the connecting portion when the door cover is in the closed position. In this way, the receiving groove 12 can protect the connecting portion 23 when the door cover is in the closed position, avoiding direct impact on the connecting portion 23 from the outside.

[0059] Specifically, the receiving groove 12 and the mounting groove 11 can be arranged along the width direction of the base, so that the receiving groove 12 and the mounting groove 11 share a groove wall, and thus the communication port on the groove wall of the mounting groove 11 can communicate the receiving groove 12 and the mounting groove 11 with each other.

[0060] The receiving groove 12 described above can be provided with a notch at one end away from the communication port along the width direction of the base, and the connecting portion 23 is arranged parallel to the base, so that when the door cover is in the closed position, part of the connecting portion 23 extends into the receiving groove 12, and the remaining part extends out of the receiving groove 12. Of course, the connecting portion 23 can also be arranged inclined relative to the door cover, and when the door cover is in the closed position, the connecting portion 23 extends into the receiving groove 12, so that the receiving groove 12 accommodates the connecting portion 23.

[0061] Referring to Figures 1 to 5As shown, in some embodiments, the energy storage mechanism includes a torsion spring, the torsion spring 42 is sleeved on the rotating shaft part 32, and two ends of the torsion spring 42 are connected with the base and the door cover respectively. In this way, the cost of the torsion spring 42 is low, and the torsion spring 42 can be sleeved on the rotating shaft part 32, so that the torsion spring 42 has good stability in the mounting groove 11, and additional structures for limiting the torsion spring 42 in the mounting groove 11 are not needed, thereby simplifying the connection structure of the base and the energy storage mechanism.

[0062] Specifically, the torsion spring 42 is a cylindrical structure formed by coiling an elastic material, and two ends of the elastic material are exposed on the cylindrical structure to form two support arms 421.

[0063] The bottom of the mounting groove 11 can be provided with a fixing hole, one support arm 421 of the torsion spring 42 is connected with the fixing hole in a plug-in manner, and the other support arm 421 is connected with the rotating shaft part 32. Of course, the inner wall of the mounting groove 11 can be provided with a buckle, one support arm 421 of the torsion spring 42 is connected with the buckle, and the other support arm 421 is connected with the rotating shaft part 32.

[0064] The rotating shaft part 32 can be provided with a buckle, one support arm 421 of the torsion spring 42 is connected with the base, and the other support arm 421 is connected with the buckle in a clamping manner, so that the rotation of the rotating shaft part 32 can drive the torsion spring 42 to rotate together. Of course, the rotating shaft part 32 can be provided with a baffle, one support arm 421 of the torsion spring 42 is connected with the base, and the other support arm 421 is abutted with the baffle along one side of the circumferential direction of the rotating shaft part 32, so that the rotation of the rotating shaft part 32 can drive the torsion spring 42 to rotate together.

[0065] Referring to Figures 1 to 7 As shown, in some embodiments, the door cover includes a door cover body 2 and a rotating support 3 fixed on the door cover body, the rotating support 3 includes a support body 31 and a rotating shaft part 32, the support body 31 is fixedly connected with the door cover body 2, and the rotating shaft part 32 is connected to one side of the support body 31.

[0066] The base includes a base body 1 and a fixed support 41, the base body 1 is provided with a mounting groove 11, the fixed support 41 is installed in the mounting groove 11 and fixedly connected with the base body 1, and the rotating shaft part 32 extends to the fixed support 41 and is rotationally connected with the fixed support 41.

[0067] Thus, the bracket body 31 and the rotating shaft part 32 are simple in structure and low in manufacturing cost, and the connection of the bracket body 31 and the door cover body 2 does not need to be provided with additional matching structure on the door cover body 2, so that the mechanism of the door cover body 2 is simple and easy to process. The fixing bracket 41 can support and rotatably connect the rotating shaft part 32, so that the mounting groove 11 does not need to be processed with structure matching the rotating connection of the rotating shaft part 32, thereby reducing the processing difficulty of the base body 1. The door cover body 2 is rotatably arranged on the base body 1 through the mutual matching of the rotating bracket 3 and the fixing bracket 41, and the rotating bracket 3 and the fixing bracket 41 simplify the structure of the door cover body 2 and the base body 1, thereby reducing the processing difficulty of the door cover body 2 and the base body 1.

[0068] The door cover body 2 described above can be selected as a panel structure, and the door cover body 2 is rotatably connected with the base body 1 through the rotating bracket 3 and the fixing bracket 41, and the door cover body 2 is rotatable relative to the base body 1 between the closed door position and the open door position. The base body 1 is the main structure of the base, and the fixing bracket 41 is arranged in the mounting groove 11 as the basic structure for rotatably connecting with the rotating shaft part 32.

[0069] The bracket body 31 described above can be selected as a rectangular bracket structure, and of course can also be selected as a bracket structure of other shapes. The rotating shaft part 32 of the rotating bracket 3 can be selected as a cylindrical shaft body. The rotating shaft part 32 is protruded on one side of the bracket body 31. The bracket body 31 and the rotating shaft part 32 can be selected to be perpendicular to each other, and of course can also be selected to be arranged to be inclined to each other between the rotating shaft part 32 and the bracket body 31. The rotating shaft part 32 is rotatably connected with the fixing bracket 41, and the bracket body 31 is fixedly connected with the door cover body 2 through welding or bolts, so that the rotating shaft part 32 is rotatable relative to the fixing bracket 41 to drive the rotating bracket 3 to rotate together, and the door cover body 2 can rotate relative to the base body 1 with the rotating shaft part 32 as the axis.

[0070] The fixing bracket 41 described above can be selected to include a bottom plate and two standing plates arranged on the same side of the bottom plate. The two standing plates are each provided with a through hole, and the rotating shaft part 32 is movably inserted into the through holes of the two standing plates, so that the rotating shaft part 32 can rotate relative to the standing plates. The bottom plate is fixedly connected with the groove bottom of the mounting groove 11 or the groove wall of the mounting groove 11. Of course, the fixing bracket 41 can also be selected as a frame structure, and the frame structure is provided with a through hole, and the rotating shaft part 32 is rotatably connected with the through hole of the frame structure. The fixing bracket 41 and the inner wall of the mounting groove 11 can be fixedly connected through bolts or welding.

[0071] Referring to Figure 1 , Figure 3 and Figures 7 to 10As shown, in some embodiments, two support arms 421 are formed at each end of the torsion spring 42, one of the support arms 421 being connected to the fixed bracket 41, and the other support arm 421 being connected to the rotating bracket 3. With this arrangement, when the rotating bracket 3 rotates relative to the fixed bracket 41, the two support arms 421 can be driven to rotate relative to each other, thereby elastically deforming the torsion spring 42. The manufacturing cost of the rotating bracket 3 and the fixed bracket 41 is low, and it is easy to process and form a connecting structure that matches the support arms 421. Furthermore, when the door cover rotates between the open position and the closed position, the rotating bracket 3 and the fixed bracket 41 rotate relative to each other, and the two support arms 421 are respectively connected to the rotating bracket 3 and the fixed bracket 41. This allows the force of the torsion spring 42 to act on the relatively rotating rotating bracket 3 and the fixed bracket 41, thereby reducing the loss of the torsion spring 42 when applying the elastic force.

[0072] Specifically, a through hole can be set on the fixed bracket 41, and a support arm 421 can be plugged into the through hole. A buckle can be set on the shaft portion 32 of the rotating bracket 3, and the other support arm 421 can be connected to the buckle. Of course, the support arm 421 can also be selected to abut against one side of the rotating bracket 3 along the circumference of the shaft portion 32, so that when the shaft portion 32 rotates relative to the fixed bracket 41, the support arm 421 can rotate relative to the fixed bracket 41 together with the rotating bracket 3.

[0073] Reference Figures 1 to 7 As shown, in some embodiments, a baffle 33 extending radially along the shaft portion is provided on the shaft portion 32, wherein one of the support arms 421 abuts against one side of the baffle 33 along the circumference of the shaft portion 32;

[0074] The fixed bracket 41 is provided with a fixing hole 43, into which another support arm 421 is inserted and abutted against the wall of the fixing hole 43. This arrangement limits the support arm 421, ensuring that the relative position of the support arm 421 and the fixed bracket 41 remains stable. The provision of the fixing hole 43 in the fixed bracket 41 facilitates operation and reduces the manufacturing cost of the fixed bracket 41. The baffle 33 has a simple structure, and the cost of manufacturing the baffle 33 on the rotating shaft portion 32 is low. Furthermore, the abutment of the support arm 421 with the baffle 33 allows the support arm 421 to rotate with the baffle 33, thereby storing energy in the torsion spring 42, simplifying the connection structure between the torsion spring 42 and the support arm 421.

[0075] Specifically, a through hole is provided on the fixed bracket 41 as a fixing hole 43, a support arm 421 is plugged into the fixing hole 43, and the other support arm 421 is in contact with the baffle 33 of the rotating bracket 3; when the rotating bracket 3 rotates, the baffle 33 drives one support arm 421 to rotate together, and the support arm 421 inside the fixing hole 43 is limited by the fixing hole 43, and the support arm 421 inside the fixing hole 43 will not rotate together with the rotating bracket 3, so that when the door cover rotates toward the base and drives the rotating bracket 3 to rotate, the torsion spring 42 undergoes elastic deformation to store elastic potential energy.

[0076] The above-mentioned baffle 33 is a panel structure arranged on the rotating shaft portion 32. The baffle 33 extends radially along the rotating shaft portion 32, and the torsion spring 42 abuts against the baffle 33 along the circumference of the rotating shaft portion 32. It can be selected that in the direction in which the door cover rotates toward the base, the support arm 421 is arranged on the side of the baffle 33 facing the base, so that when the door cover rotates toward the base to the closed position, the baffle 33 drives the support arm 421 to rotate toward the base together, so that the torsion spring 42 elastically deforms and applies an elastic force to the door cover in the direction away from the base as resistance.

[0077] Reference Figures 1 to 3 and Figures 8 to 10 As shown, in some embodiments, the angle between the two support arms 421 when the door cover is in the closed position is a1, the angle between the two support arms 421 when the door cover is in the open position is a2, and the angle between the two support arms in the natural state is a3, a3>a2>a1.

[0078] With such arrangement, the torsion spring 42 also applies an elastic force to the door cover when the door cover is in the open position, so that the door cover can be easily maintained in the open position under the action of the elastic force; when the door cover is in the closed position, the elastic deformation of the torsion spring 42 is the largest. When the user opens the door cover, the user's arm force posture is more strenuous for opening the door cover from the closed position in contact with the base. At this time, the torsion spring 42 can apply a larger elastic force to the door cover, so that the torsion spring 42 has a better assisting effect on the opening of the door cover, making it convenient for the user to drive the door cover to move from the closed position to the open position.

[0079] Specifically, when the door cover is attached to the base and covers the delivery port on the base, the door cover is in the closed position; when the door cover rotates in a direction away from the base and the door cover rotates to a position where the angle between the door cover and the base is greater than or equal to 90°, the door cover's own gravity will not cause the door cover to rotate toward the base to cover the delivery port of the base, or the door cover will not block the delivery port of the base in the axial direction of the delivery port, the door cover is in the open position.

[0080] The above-mentioned torsion spring 42 does not undergo elastic deformation in the natural state. At this time, the torsion spring 42 does not store elastic potential energy, and the two support arms 421 will not apply elastic force to the door cover and the base. When the door cover is in the open position, the angle between the two support arms 421 is a2, and a2 is smaller than a1. At this time, the torsion spring 42 is in a compressed elastic deformation state and stores elastic potential energy. The two support arms 421 will have a tendency to move away from each other under the elastic force of the torsion spring 42, so that the two support arms 421 apply elastic force to the base and the door cover respectively, so that the torsion spring 42 applies an elastic force to the door cover to rotate in the direction away from the base. The elastic force of the torsion spring 42 is conducive to keeping the door cover in the open state.

[0081] When the above-mentioned door cover is in the closed state, the angle a1 is smaller than the angle a2. The smaller the angle between the two support arms 421 of the torsion spring 42, the greater the elastic potential energy stored in the torsion spring 42, and the greater the elastic force exerted by the two support arms 421 of the torsion spring 42 on the base and the door cover. As a result, when the door cover is in the closed state, the elastic force exerted by the torsion spring 42 on the door cover is greater. When the user pulls the door cover by hand to rotate the door cover away from the base to open the door cover, the elastic force of the torsion spring 42 is greater and can assist in opening the door cover.

[0082] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the door cover body 2 includes a first cover body 21 and a second cover body 22, which are connected to each other in a covering manner, and the rotating bracket 3 is sandwiched between the first cover body 21 and the second cover body 22. In this arrangement, the first cover body 21 and the second cover body 22 can cover the rotating bracket 3, so that the bracket body 31 of the rotating bracket 3 is not exposed on the outside of the door cover, thereby improving the aesthetics of the door cover.

[0083] Specifically, the first cover 21 can be a panel structure, and the second cover 22 can be a frame structure.

In this way, the number of energy storage mechanisms is two, so that the door cover can be rotatably arranged on the base by the two energy storage mechanisms and the two rotating supports 3, the door cover has two rotating connection points with the base, which can improve the stability of the door cover when rotating; when the door cover rotates from the closed position to the open position, the torsional springs 42 of the two energy storage mechanisms can provide assistance to the door cover, and when the door cover rotates from the open position to the closed position, the two torsional springs 42 can form resistance to the door cover, which improves the effect of slowing down the rotation of the door cover towards the base, so that the energy storage mechanism has better resistance and assistance effect when the door cover rotates.

[0087] Specifically, the base is respectively provided with an energy storage mechanism at opposite side edges in the width direction, and the two energy storage mechanisms, and the axes of the two rotating shaft parts 32 are on the same straight line, i.e., the door cover can rotate relative to the base with the two rotating shaft parts 32 as the axis.

[0088] The number of fixed brackets 41 and rotating brackets 3 can be two, with the two fixed brackets 41 located at opposite edges of the door cover along the width direction, and the two fixed brackets 41 are arranged in a one-to-one correspondence with the two energy storage mechanisms. The two energy storage mechanisms and the two rotating brackets 3 are mirrored along a plane perpendicular to the width direction of the base, so that when the door cover rotates toward the base, the torsion springs 42 of the two energy storage mechanisms store energy, providing resistance to the door cover's rotation toward the base.

[0089] The above-mentioned base is respectively provided with a mounting groove 11 at the two side edges along the width direction, and the energy storage mechanism is arranged in the mounting groove 11. Of course, it is also possible to select two mounting grooves 11 and respectively provide a corresponding accommodating groove 12, so that when the door cover is in the closed state, the two bracket bodies 31 can be respectively arranged in the two accommodating grooves 12.

[0090] Reference Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the door cover device further includes a cover plate 13, which extends along the width of the base and covers the mounting slot 11. The cover plate 13 is connected to the base. This arrangement allows the cover plate 13 to cover the mounting slot 11, protecting the two energy storage mechanisms and preventing foreign matter or dust from entering the mounting slot 11 and affecting the normal operation of the energy storage mechanisms. Furthermore, the cover plate 13 covers the mounting slot 11, preventing the mounting slot 11 and the energy storage mechanism from being exposed outside the door cover device, thereby improving the aesthetics of the door cover device.

[0091] Specifically, the cover plate 13 is extended along the width direction of the base. When two mounting grooves 11 are provided on the base, the cover plate 13 covers the two mounting grooves 11 and is connected to the base.

[0092] The aforementioned base is the main structure of the home appliance, and the cover 13 can be selected as the control panel of the home appliance. The control panel is connected to the base and can cover the two mounting slots 11, so that the mounting slots 11 are not directly exposed on the base. Of course, the cover 13 can also be selected as a panel structure, which covers the mounting slots 11 and protects the energy storage mechanism within the mounting slots 11. The cover 13 can be adhesively connected to the base, or it can be connected to the base using bolts.

[0093] Reference Figure 2 As shown, in some embodiments, the cover plate serves as a control panel. This arrangement allows the cover plate 13 to be exposed on the base, making it easier for the user to operate the control panel. Furthermore, the cover plate 13 covers the mounting slot 11, protecting the energy storage mechanism. By utilizing the control panel of the clothing processing device as the cover plate 13, the number of parts in the clothing processing device can be reduced, lowering the manufacturing cost of the door cover assembly.

[0094] Specifically, the base is arranged on the clothes treatment device, which usually has multiple electric components and a control panel, and the control panel is electrically connected with the multiple electric components, so that the control panel can control the working state of the multiple electric components. The cover plate 13 is the control panel, and the cover plate 13 is exposed on the base to facilitate user operation, and the cover plate 13 can cover the mounting groove 11 to protect the energy storage mechanism.

[0095] Referring to Figures 1 to 4 As shown in the drawings, in some embodiments, the door cover has two connection portions protruding from opposite ends in the width direction, respectively, and the two connection portions protrude towards one side of the door cover, and an installation opening is formed between the two connection portions; the control panel is located between the two connection portions and is exposed through the installation opening. In this way, when the door cover is connected with the base, the relative positions of the door cover and the base are positioned through the cooperation of the installation opening formed by the two connection portions 23 and the control panel; and the installation opening enables the control panel to be exposed on the base, facilitating user operation. The connection portions 23 also protect the two sides of the control panel in the width direction of the base.

[0096] Specifically, the connection portions 23 can be selected as rectangular or other shaped protruding structures, and the two connection portions 23 are spaced apart from each other in the width direction of the door cover, so that the space between the two connection portions 23 forms an installation opening, and after the door cover is rotationally connected with the base, the two connection portions 23 are respectively located on the two sides of the control panel, so that the control panel is located in the installation opening.

[0097] The two connection portions 23 can be selected to correspond to two shaft portions 32, so that the two shaft portions 32 are rotationally connected with the base on the two sides in the width direction, or the two connection portions 23 can be selected to be connected with the two rotating supports 3, respectively, so that the shaft portions 32 on the two rotating supports 3 are rotationally connected with the base on the two sides in the width direction.

[0098] The second aspect of the present application provides a clothes treatment device including the door cover device as described above. The clothes treatment device can be selected as a washing machine, a clothes dryer or other clothes treatment device, and the clothes treatment device can be selected as an upper opening door type, i.e., the shaft portion 32 is arranged in the horizontal direction, so that the door cover can be rotated upward relative to the base to open the door cover.

[0099] By using the door cover device as described above in the clothes treatment device, the energy storage mechanism is mounted on the base, and the door cover only needs to be connected with the support body 31, so that the door cover can be rotationally arranged on the base, and the energy storage mechanism provides resistance when the door cover is rotated at the door closing position, so as to slow down the falling speed of the door cover, avoid the collision between the door cover and the base to generate abnormal sound and injure the user, and the energy stored by the energy storage mechanism can provide assistance when the door cover is opened, so as to reduce the force required by the user to open the door cover when the door cover is rotated towards the door opening position, and facilitate the user to open the door cover.

[0100] In use, the bottom plate 411 is connected to the groove bottom of the mounting groove 11, the rotating shaft part 32 is inserted into the mounting groove 11 from the communication opening, the rotating shaft part 32 is rotationally connected to the rotating holes 413 on the two vertical plates 412, the support body 31 is arranged in the containing groove 12, the connecting part 23 is arranged in the containing groove 12 and connected to the support body 31, and the support body 31 is clamped between the first cover body 21 and the second cover body 22.

[0101] When the door cover is attached to the base in the closed door position, the included angle between the two supporting arms 421 of the torsional spring 42 is a1, the torsional spring 42 stores elastic potential energy at this time, and the torsional spring 42 exerts an elastic force on the door cover in the direction away from the base. When the user pulls the door cover with his hand to rotate the door cover toward the open door position, the elastic force of the torsional spring 42 can assist the door cover to rotate toward the open door position, so that the user can pull the door cover to the open door position with less force.

[0102] When the door cover is in the open door position, the included angle between the two supporting arms 421 is a2, and the torsional spring 42 exerts an elastic force on the door cover in the direction away from the base, so that the door cover can be kept in the open door position.

[0103] When the door cover rotates from the open door position toward the closed door position, the included angle of the torsional spring 42 gradually decreases, so that the force exerted by the torsional spring 42 on the door cover gradually increases, thereby slowing down the speed of the door cover rotating toward the closed door position, avoiding the door cover colliding with the base when the door cover is quickly closed on the base, and avoiding the door cover from producing an abnormal sound and easily injuring the user.
