Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a washing machine. Background Art

[0002] The washing machine includes a control panel seat, and an upper cover is installed at the clothing input port of the control panel seat. One end of the upper cover is connected to the control panel seat by a hinge, and the upper cover can be opened or closed relative to the control panel seat by the hinge. In the prior art, an elastic device is generally provided between the upper cover and the control panel seat to slow down the closing speed of the upper cover and play a buffering role. However, since the upper cover of an industrial washing machine is usually made of a metal plate and is very heavy, the existing upper cover damping cannot well solve the problem of the upper cover closing slowly during the whole process, so that the closing speed of the upper cover cannot be effectively slowed down, and the user needs to use a lot of force to open the upper cover; and in addition, at a position where the upper cover is close to the closed position, the damping force is relatively small, and the user often exerts force to overcome the damping force to ensure the rapid closing of the upper cover. However, if the force is not properly controlled, the force will be too large to overcome the buffering effect of the damping force, resulting in a sudden increase in the closing speed of the lower cover, which can easily cause the upper cover to suddenly fall and injure the user's fingers. Furthermore, an excessive closing force will also damage the upper cover and shorten the service life of the upper cover.

[0003] The Chinese patent application number CN201310728859.X discloses an auxiliary structure for opening and closing the upper cover of a washing machine and a washing machine. The auxiliary structure for opening and closing the upper cover is arranged between the upper cover and the washing machine pan seat, and includes a damping device, a spring matched with the damping device, and a transmission mechanism. When the upper cover is closed, the damping device cooperates with the spring to apply a torque to the upper cover through the transmission mechanism. When the upper cover is closed, the direction of the torque is opposite to the direction of closing the upper cover, and when the upper cover is opened, the direction of the torque is the same as the direction of opening the upper cover.

[0004] A Chinese patent application numbered CN201521078401.5 discloses a washing machine comprising a pan seat, a damper fixedly mounted in the pan seat, a decorative frame mounted outside the damper, and an upper cover rotatably connected to the pan seat; the upper cover is provided with a rotating shaft, which is rotatably mounted to the pan seat and assembled with the damper.

[0005] Although the above-mentioned prior art proposes a structure for setting a damper between the upper cover and the disc base, the damper exerts a force during the entire opening process of the upper cover, making the opening process of the upper cover time-consuming and labor-intensive, and the structure is complex and not conducive to mass production. At the same time, it is easy to be damaged, difficult to maintain, and costly.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing machine that can overcome the above problems or at least partially solve the above problems.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a washing machine, comprising

[0009] A pan base, and an upper cover connected to the pan base;

[0010] A damper is arranged on the disc seat;

[0011] A stopper, arranged on one side of the bottom surface of the upper cover;

[0012] During the closing process of the upper cover, the damper abuts against the stopper to provide a buffering damping force to the upper cover.

[0013] The stopper compresses the damper along the axial direction of the damper to generate a buffer damping force along the axial direction of the damper, and the damper is deformed in the axial direction. The compressed damper generates a buffer damping force when the upper cover is closed.

[0014] In addition, one end of the damper is arranged on one side where the pan base and the upper cover are hinged, and the other end extends away from the side where the pan base and the upper cover are hinged;

[0015] The stopper corresponds to the damper and is arranged at a side close to the hinge between the upper cover and the disc base. Specifically, the damper is arranged at the connection between the disc base and the upper cover. This arrangement enables the damper to generate a buffering damping force on the upper cover earlier, thereby better avoiding injuring the user's hand.

[0016] Furthermore, the other end of the damper is arranged horizontally or inclined upward;

[0017] After the upper cover is closed, the level of the other end of the damper is higher than the level of the lowest end of the stopper, and lower than the level of the connection position of the stopper to the bottom surface of the upper cover.

[0018] Moreover, the bottom surface of the upper cover is provided with a groove for accommodating the stopper;

[0019] When the upper cover is in the process of being closed, the stopper can be extended out of the groove;

[0020] In one embodiment, when the upper cover is in an open state, the block enters the groove and is in the same plane as the bottom surface of the upper cover. The block is completely received in the bottom surface of the upper cover, thereby increasing the beauty of the upper cover and avoiding the block from being scratched when taking and placing clothes due to protrusions when the upper cover is in an open state.

[0021] At the same time, a first guide portion is provided on the stopper;

[0022] The groove is provided with a second guide portion which cooperates with the first guide portion and is used to guide the movement direction of the stopper in the groove.

[0023] Further, the first guide portion is a slideway;

[0024] The second guide portion is a slide rail provided on the side wall of the groove and matched with the slideway of the first guide portion. Specifically, the stopper is slidably connected to the groove. As the upper cover is opened and closed, the stopper slides in the groove. When the upper cover is in a closed state, the stopper is in a state of protruding from the groove, thereby matching with the damper to generate a buffer damping force.

[0025] In a specific embodiment, the first guide portion and the second guide portion extend from the bottom surface of the upper cover to the top surface, and are inclined toward one side of the hinge between the upper cover and the tray seat;

[0026] In a specific embodiment, when the upper cover switches from the open state to the closed state, the stopper switches from a state of being accommodated in the groove to a state of protruding from the groove along a motion trajectory formed by the first guide portion and the second guide portion.

[0027] Further, the first guide portion is a columnar structure;

[0028] The second guide portion is a hole-shaped structure disposed on the side wall of the groove and matched with the columnar structure of the first guide portion;

[0029] The extension line of the side wall intersects with the hinged portion between the upper cover and the disk seat. Specifically, the stopper is rotatably connected to the groove. As the upper cover is opened and closed, the stopper rotates around a rotation axis in the groove. When the upper cover is in a closed state, the stopper is in a state of protruding from the groove, thereby cooperating with the damper to generate a buffering force.

[0030] In a specific embodiment, the second guide portion is disposed on the side wall at an end away from the hinged connection between the upper cover and the tray seat;

[0031] In a specific embodiment, when the upper cover switches from the open state to the closed state, the stopper rotates around the rotation axis formed by the first guide portion and the second guide portion, switching from a state of being received in the groove to a state of protruding from the groove.

[0032] Furthermore, the damper is disposed on the disc seat, facing upward;

[0033] The stopper is arranged on the bottom surface of the upper cover.

[0034] In a specific embodiment, the damper is arranged on the disc base, away from a side where the disc base and the upper cover are hinged;

[0035] The block is on the bottom surface of the upper cover, corresponding to the damper, and is arranged at a side away from the disc base and hinged with the upper cover. Specifically, the damper is arranged at the front end of the disc base, and the block is arranged at the front end of one side of the bottom surface of the upper cover. When the upper cover is closed, the block squeezes the damper to generate a buffering force for the closing of the upper cover, thereby playing a buffering role.

[0036] In addition, the damper is any one of hydraulic damping, gas pressure damping and spring damping.

[0037] Furthermore, it also includes

[0038] A rotating shaft is arranged on one side of the disc seat;

[0039] The upper cover is rotatably connected to the disc seat via a rotating shaft. By arranging the rotating shaft connection between the disc seat and the upper cover, the upper cover is easier to open and close, avoiding the need to apply a force to overcome the hinge.

[0040] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: the washing machine described in the present invention, by arranging the block on the bottom surface of the upper cover, and arranging the damper corresponding to the block on the disc base, so that during the closing process of the upper cover, the block cooperates with the damper to generate a buffering force for the closing of the upper cover, thereby preventing users from injuring their fingers and preventing the upper cover from being damaged by collision.

[0053] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0055] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0056] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] like Figures 1 to 3 As shown, the first schematic diagram of the washing machine of the present invention, the first schematic diagram of the stopper 4 and the first schematic diagram of the upper cover 2, in order to facilitate the observation of the present invention, the structure of the disc base 1 and the upper cover 2 is simplified. Figures 1 to 3 It can be seen that one end of the damper 3 is arranged on one side where the disc base 1 and the upper cover 2 are hinged, and the other end extends in a direction away from the side where the disc base 1 and the upper cover 2 are hinged. The other end of the damper 3 is arranged horizontally or inclined upward. After the upper cover 2 is closed, the horizontal height of the other end of the damper 3 is higher than the horizontal height of the lowest end of the stopper 4 and lower than the horizontal height of the connection position between the stopper 4 and the bottom surface of the upper cover 2; the bottom surface of the upper cover 2 is provided with a stopper 4 that cooperates with the damper 3. During the closing process of the upper cover 2, the stopper 4 squeezes the damper 3 in the axial direction of the damper 3 to produce deformation, thereby generating a damping buffering force on the upper cover 2, thereby avoiding the risk of the user's hand being injured during the closing process of the upper cover 2. Figures 1 to 3 In the figure, an implementation scheme of the block 4 is shown. Specifically, a groove 201 is provided in the upper cover 2, and the block 4 can be received in the groove 201. When the upper cover 2 is in an open state, the block 4 is received in the groove 201, thereby avoiding a bulge when the upper cover 2 is in an open state, which affects the overall appearance. Furthermore, in order to facilitate the sliding of the block 4 in the groove 201, a slide is provided on the block 4, and corresponding to the slide, a slide rail is provided in the groove 201. Furthermore, on the bottom plane of the upper cover 2, the slide and the slide rail are inclined toward the hinge between the upper cover 2 and the disc base 1, so that when the upper cover 2 is in an open state, the block 4 obtains the power to slide into the groove 201.

[0058] Further, the upper cover 2 may be the upper cover for opening and closing the clothing inlet of the tray 1, or the upper cover 2 may be the upper cover 2 for opening and closing the opening of the detergent box.

[0059] like Figures 4 to 6 As shown, it is a second schematic diagram of the washing machine of the present invention, a second schematic diagram of the stopper 4 and a second schematic diagram of the upper cover 2, which are the same as the Figures 1 to 3 The principle of the technical solution in is similar to that in Figures 4 to 6In the technical solution, one end of the damper 3 is also arranged on the side where the disc base 1 and the upper cover 2 are hinged, and the other end extends away from the side where the disc base 1 and the upper cover 2 are hinged. The other end of the damper 3 is arranged horizontally or inclined upward. After the upper cover 2 is closed, the horizontal height of the other end of the damper 3 is higher than the horizontal height of the lowest end of the stopper 4 and lower than the horizontal height of the connection position between the stopper 4 and the bottom surface of the upper cover 2; the bottom surface of the upper cover 2 is provided with a stopper 4 that cooperates with the damper 3. During the closing process of the upper cover 2, the stopper 4 squeezes the damper 3 in the axial direction of the damper 3 to produce deformation, thereby generating a damping buffering force on the upper cover 2, thereby avoiding the risk of the user's hand being injured during the closing process of the upper cover 2, but unlike Figures 1 to 3 The difference between the technical solutions shown in Figures 4 to 6 In the embodiment, the stopper 4 and the groove 201 are not connected by sliding but by rotation. Specifically, a columnar structure is provided on the stopper 4, and a hole structure cooperating with the columnar structure is provided in the groove 201. Furthermore, the hole structure is provided in the groove 201 on the side wall away from the hinged end of the upper cover 2 and the disc base 1, so that the stopper 4 can automatically fall down as the upper cover 2 is closed, and automatically retract into the groove 201 as the upper cover 2 is opened.

[0060] Further, the upper cover 2 may be the upper cover for opening and closing the clothing inlet of the tray 1, or the upper cover 2 may be the upper cover 2 for opening and closing the opening of the detergent box.

[0061] like Figure 7 and Figure 8 As shown, there are the third schematic diagram and the fourth schematic diagram of the washing machine of the present invention, which are mainly used to show the technical solution that the damper 3 is arranged at the front end of the disc seat 1, wherein the axial direction of the damper 3 is arranged toward the top of the washing machine, and corresponding to the damper 3, the stopper 4 is arranged on the bottom surface of the upper cover 2. In this technical solution, the stopper 4 and the upper cover 2 are relatively fixedly connected, that is, the stopper 4 and the upper cover 2 cannot move relative to each other.

[0062] Further, the upper cover 2 may be the upper cover for opening and closing the clothing inlet of the tray 1, or the upper cover 2 may be the upper cover 2 for opening and closing the opening of the detergent box.

[0063] The washing machine described in the present invention is provided with the stopper 4 on the bottom surface of the upper cover 2, and the damper 3 corresponding to the stopper 4 is provided on the disc base 1, so that during the closing process of the upper cover 2, the stopper 4 cooperates with the damper 3 to generate a buffering force for the closing of the upper cover 2, thereby preventing the user from injuring his fingers and the upper cover 2 from being damaged by collision during the closing process of the upper cover 2. The present invention is applied to a specific implementation scheme as described below.

[0064] In a specific embodiment, Figures 1 to 3 As shown, a washing machine described in the present invention comprises a disc base 1 and an upper cover 2 connected to the disc base 1; a damper 3 is arranged on the disc base 1; a stopper 4 is arranged on one side of the bottom surface of the upper cover 2; during the closing process of the upper cover 2, the damper 3 abuts against the stopper 4 to provide the upper cover 2 with a buffering damping force.

[0065] The stopper 4 presses the damper 3 along the axial direction of the damper 3 to generate a buffer damping force along the axial direction of the damper 3. The damper 3 is deformed in the axial direction, and the compressed damper 3 generates a buffer damping force when the upper cover 2 is closed.

[0066] In addition, one end of the damper 3 is arranged on the side where the disc base 1 and the upper cover 2 are hinged, and the other end extends away from the side where the disc base 1 and the upper cover 2 are hinged; the stopper 4 is arranged on the bottom surface of the upper cover 2, close to the side where the upper cover 2 and the disc base 1 are hinged. Specifically, the damper 3 is arranged at the connection between the disc base 1 and the upper cover 2. This arrangement allows the damper 3 to generate a buffering damping force on the upper cover 2 earlier, thereby better avoiding injuring the user's hand.

[0067] Furthermore, the other end of the damper 3 is horizontally arranged or tilted upward; after the upper cover 2 is closed, the horizontal height of the other end of the damper 3 is higher than the horizontal height of the lowest end of the block 4, and lower than the horizontal height of the connection position between the block 4 and the bottom surface of the upper cover 2. This arrangement enables the damper 3 to cooperate with the block 4 to achieve a buffering and damping effect on the upper cover 2.

[0068] Furthermore, the bottom surface of the upper cover 2 is provided with a groove 201 for accommodating the stopper 4; when the upper cover 2 is closed, the stopper 4 can be extended out of the groove 201;

[0069] As a preferred technical solution of this embodiment, at least when the upper cover 2 is in the open state, the block 4 enters the groove 201 and is in the same plane as the bottom surface of the upper cover 2. The block 4 is completely received in the bottom surface of the upper cover 2, which increases the beauty of the upper cover 2, avoids the upper cover 2 being in the open state with a bulge that destroys the overall beauty, and avoids the block 4 being scratched when taking clothes out of the washing machine drum.

[0070] Furthermore, a first guide portion 401 is disposed on the stopper 4 ; and a second guide portion 202 is disposed in the groove 201 and cooperates with the first guide portion 401 to guide the movement direction of the stopper 4 in the groove 201 .

[0071] Furthermore, the first guide portion 401 is a slideway; the second guide portion 202 is a slide rail arranged on the side wall of the groove 201 and cooperates with the columnar structure of the first guide portion 401. Specifically, the block 4 is slidably connected to the groove 201. As the upper cover 2 is opened and closed, the block 4 slides in the groove 201. When the upper cover 2 is in a closed state, the block 4 is in a state of protruding from the groove 201, thereby cooperating with the damper 3 to generate a buffering damping force.

[0072] As a preferred technical solution of this embodiment, the first guide portion 401 and the second guide portion 202 are arranged to extend from the bottom surface to the top surface of the upper cover 2 and be inclined toward one side of the hinge between the upper cover 2 and the disk base 1.

[0073] Furthermore, when the upper cover 2 switches from the open state to the closed state, the stopper 4 switches from a state of being received in the groove 201 to a state of protruding from the groove 201 along a motion trajectory formed by the first guide portion 401 and the second guide portion 202 .

[0074] As a preferred technical solution of this embodiment, the damper 3 is any one of hydraulic damping, gas pressure damping and spring damping.

[0075] In a specific embodiment, Figures 4 to 6 As shown, a washing machine described in the present invention comprises a disc base 1 and an upper cover 2 connected to the disc base 1; a damper 3 is arranged on the disc base 1; a stopper 4 is arranged on one side of the bottom surface of the upper cover 2; during the closing process of the upper cover 2, the damper 3 abuts against the stopper 4 to provide the upper cover 2 with a buffering damping force.

[0076] The stopper 4 presses the damper 3 along the axial direction of the damper 3 to generate a buffer damping force along the axial direction of the damper 3. The damper 3 is deformed in the axial direction, and the compressed damper 3 generates a buffer damping force when the upper cover 2 is closed.

[0077] In addition, one end of the damper 3 is arranged on the side where the disc base 1 and the upper cover 2 are hinged, and the other end extends away from the side where the disc base 1 and the upper cover 2 are hinged; the stopper 4 is arranged on the bottom surface of the upper cover 2, close to the upper cover 2 and on the side where the upper cover 2 is hinged. Specifically, the damper 3 is arranged at the connection between the disc base 1 and the upper cover 2. This arrangement allows the damper 3 to generate a buffering damping force on the upper cover 2 earlier, thereby better avoiding injuring the user's hand.

[0078] Furthermore, the other end of the damper 3 is horizontally arranged or tilted upward; the horizontal height of the other end of the damper 3 is lower than the horizontal height of the bottom surface of the upper cover 2 after closing, and higher than the horizontal height of the lowest end of the stopper 4. This arrangement enables the damper 3 to cooperate with the stopper 4 to achieve a buffering and damping effect on the upper cover 2.

[0079] Furthermore, the bottom surface of the upper cover 2 is provided with a groove 201 for accommodating the stopper 4; when the upper cover 2 is closed, the stopper 4 can be extended out of the groove 201;

[0080] As a preferred technical solution of this embodiment, at least when the upper cover 2 is in the open state, the block 4 enters the groove 201 and is in the same plane as the bottom surface of the upper cover 2. The block 4 is completely received in the bottom surface of the upper cover 2, which increases the beauty of the upper cover 2, avoids the upper cover 2 being in the open state with a bulge that destroys the overall beauty, and avoids the block 4 being scratched when taking clothes out of the washing machine drum.

[0081] Meanwhile, a first guide portion 401 is disposed on the stopper 4 ; and a second guide portion 202 cooperating with the first guide portion 401 and used for guiding the movement direction of the stopper 4 in the groove 201 is disposed in the groove 201 .

[0082] Further, the first guide portion 401 is a columnar structure; the second guide portion 202 is a hole-shaped structure arranged on the side wall of the groove 201 and matched with the columnar structure of the first guide portion 401; the extension line of the side wall intersects with the hinge between the disc base 1 and the upper cover 2. Specifically, the stopper 4 is rotatably connected to the groove 201. As the upper cover 2 is opened and closed, the stopper 4 rotates around a rotation axis in the groove 201. When the upper cover 2 is in the closed state, , the stopper 4 is in a state of protruding from the groove 201, so as to cooperate with the damper 3 to generate a buffering force; the position at which the second guide portion 202 is arranged on the side wall is an end away from the hinge between the upper cover 2 and the disc base 1; when the upper cover 2 is switched from the open state to the closed state, the stopper 4 rotates around the rotation axis formed by the first guide portion 401 and the second guide portion 202, and switches from the state of being received in the groove 201 to the state of protruding from the groove 201.

[0083] As a preferred technical solution of this embodiment, the damper 3 is any one of hydraulic damping, gas pressure damping and spring damping.

[0085] The stopper 4 presses the damper 3 along the axial direction of the damper 3 to generate a buffer damping force along the axial direction of the damper 3. The damper 3 is deformed in the axial direction, and the compressed damper 3 generates a buffer damping force when the upper cover 2 is closed.
