Description

Technical Field

[0001] The invention belongs to the field of household appliances, and in particular relates to a foldable upper cover structure and a washing device. Background Art

[0002] In order to facilitate opening and closing and save space in the prior art, the upper cover of household pulsator washing machines is designed as a folding structure, which is composed of a front door cover and a rear door cover hinged together. It is relatively easy to open. The user only needs to pull the front door cover to fold the front door cover and the rear door cover. The user does not need to raise his hand to open the folding door cover. However, when closing the upper cover, it is necessary to apply an upward force to the handle on the front door cover to relatively open the front door cover and the rear door cover, and then apply a downward force to the handle to cover the upper cover on the machine body. However, the speed of closing the upper cover is generally fast. In the process of applying a downward force to the handle, the front door cover and the rear door cover will be relatively folded, resulting in the upper cover being folded. The upper cover cannot be fastened to the machine body at one time, so that the upper cover is in an abnormal covering state, which causes inconvenience to the user and brings a bad life experience to the user.

[0003] A Chinese patent application with application number CN201320883403.6 discloses a positionable foldable washing machine cover, comprising a front cover and a rear cover which are hinged to each other, the rear cover extending a covering edge at the connection, the front cover having a recessed receiving groove at the connection, the covering edge and the receiving groove being able to form a matching fit, a positioning assembly being arranged between the covering edge and the receiving groove, the bottom edge of the rear cover being hinged to the washing machine body, a positioning magnet being built-in at the bottom edge of the rear cover, and a suction magnet being correspondingly arranged at the edge of the washing machine body, the positioning magnet and the suction magnet being able to form a magnetic attraction when aligned.

[0004] In the above scheme, the positionable foldable washing machine cover is provided with a fixing part at the joint of the front cover and the rear cover to fix the front cover and the rear cover relatively in order to prevent the cover from not closing when the cover is open. When the cover needs to be folded, the fixed state of the fixing part is released, which makes the folding process extremely complicated and fails to achieve the purpose of providing convenience for users.

[0005] In view of the above technical deficiencies, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a foldable upper cover structure which can prevent two cover bodies from folding relative to each other during the closing process of the upper cover.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A foldable upper cover structure comprises a first cover body and a second cover body which can be folded relative to each other; and further comprises:

[0009] A locking unit is installed at a relatively folded position between the first cover and the second cover, and is used to lock and unlock the relative connection state between the first cover and the second cover, so that the second cover is respectively in an unfolded state maintained in the extension direction of the first cover and in a free state provided by the gravity of the second cover and relatively rotating with the first cover;

[0010] The control device is connected to the locking unit and is used to control the locking and unlocking states of the locking unit.

[0011] By adopting the above scheme, the control device can control the two states of the locking unit, and the relative connection state of the first cover body and the second cover body can be locked and unlocked by the locking unit, so that the second cover body can be in an unfolded state maintained in the extension direction of the first cover body, and can also be in a free state provided by the gravity of the second cover and relatively rotated with the first cover body. Therefore, the unfolded or free state of the second cover body can be achieved by controlling the control device. When the upper cover structure is closed, the control device can be operated to effectively prevent the second cover body from folding, thereby achieving a one-time closing of the upper cover, which provides convenience for users.

[0012] Furthermore, the control device is an electric control device, and the electric control device is electrically connected to the locking unit.

[0013] Furthermore, the electronic control device comprises:

[0014] a power supply unit, electrically connected to the locking unit and used to supply power to the locking unit;

[0015] The switch part is connected to the power supply part and is used for controlling the on and off of the power supply part circuit.

[0016] By adopting the above solution, the electric control device can not only ensure the accuracy of the on and off state of the switch, but also provide convenience for the user, saving time and effort.

[0017] Further, the locking unit includes a magnetic component for providing a magnetic attraction force for the second cover to maintain the unfolded state;

[0018] Preferably, the magnetic component is an electromagnet, and the control device controls the power on and off of the electromagnet;

[0019] Preferably, the electromagnet is mounted on the first cover; and the position of the second cover opposite to the electromagnet is made of metal or is provided with a magnet.

[0020] By adopting the above scheme, the control device can control the on and off state of the electromagnet, control whether the electromagnet is magnetic, and then control the magnetic attraction of the electromagnet. This setting method is simple, flexible, convenient, easy to operate, and quick to respond. It can also ensure the magnetic attraction connection effect between the second cover body and the first cover body when the second cover body is in the unfolded state. In addition, the electromagnet is installed on the first cover body. Since the state of the first cover body is fixed, it is convenient to electrically connect with the electronic control device.

[0021] Another object of the present invention is to provide a washing device having the above-mentioned foldable upper cover structure, comprising a dish seat, and at least part of the structure of the control device is installed on the dish seat.

[0022] By adopting the above solution, the second cover body of the upper cover structure of the washing device can be effectively prevented from being folded when it is covered on the dish seat, so that the upper cover structure can be covered once, which provides convenience for users.

[0023] Furthermore, it also includes a hinged portion, which is installed on one end of the first cover body away from the second cover body and the disc seat, and is used to hinge the first cover body and the disc seat; the first cover body can rotate around the hinged portion;

[0024] At least part of the structure of the control device is installed near the hinge position of the tray base and the first cover body.

[0025] Furthermore, the control device comprises

[0026] a power supply unit, mounted on the disc base, electrically connected to the locking unit, and used to supply power to the locking unit;

[0027] A wire, one end of which is connected to the power supply unit, and the other end of which passes through the hinged portion and is connected to the locking unit;

[0028] The switch part is connected to the power supply part and is used for controlling the on and off of the power supply part circuit.

[0029] By adopting the above solution, the control device is an electronic control device, which electronically controls the locking unit, thus providing convenience for the user.

[0030] Furthermore, the switch portion includes two conductive contacts, one end of the two conductive contacts is connected to the power supply portion, and the other end of at least one of the conductive contacts is a movable end.

[0031] Furthermore, a toggle unit is installed on the first cover body, which is used to toggle the movable end of the conductive contact piece to connect and disconnect the two conductive contacts;

[0032] Preferably, the toggle unit is mounted on the hinge portion.

[0033] Furthermore, the first cover has the following two states:

[0034] In the first state, the included angle between the first cover and the disc seat is smaller than a set value, the toggle unit toggles the movable end of the conductive contact piece, the two conductive contact pieces touch, and the control device is powered on;

[0035] In the second state, the included angle between the first cover and the disc seat is greater than or equal to a set value, the other ends of the two conductive contacts are disconnected, and the control device is powered off.

[0036] By adopting the above scheme, the relative position of the first cover body and the tray seat controls the on-off state of the control device, and the switch part of the control device can be automatically opened and closed without manual operation by the user, which is simple and convenient. In addition, in the process of closing the upper cover structure, when reaching the specified position, under the action of the control device, the second cover body can be automatically unfolded without relative folding, ensuring the one-time closing of the upper cover structure. When the upper cover structure does not need to be closed, the second cover body is in a free state, which does not affect the folding effect. It is simple and convenient, providing convenience for users.

[0037] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0038] 1. Use the control device to control the unlocking and locking states of the locking unit, and then control the unfolding and free state of the second cover body of the upper cover structure. In the process of closing the upper cover structure, you only need to operate the control device to unfold the second cover body and prevent the second cover body from folding relative to the first cover body, thereby achieving a one-time closing of the upper cover structure, which provides convenience for users. In the free state of the second cover body of the upper cover structure, the folding effect of the foldable upper cover structure can be exerted to reduce the occupied space, and it can also effectively prevent the upper cover structure from not being able to be closed in place at one time.

[0039] 2. Through the setting of the control device and the electromagnet, the control device is energized, the electromagnet has a magnet, can provide magnetic attraction for the two cover bodies of the upper cover structure, and the second cover body is in an expanded state relative to the first cover body; conversely, the electromagnet loses its magnetism, the two cover bodies lose their magnetic attraction, and the second cover body is in a free state. It is simple, flexible, convenient, easy to operate, and quick to respond, and can ensure the magnetic attraction connection effect of the second cover body with the first cover body in the expanded state.

[0040] 3. The washing device of the present invention controls the power on and off state of the control device through the relative position of the first cover body and the dish seat, and the user does not need to manually operate the control device, and the control device can be automatically powered on and off, which is simple and convenient. In addition, in the process of closing the upper cover structure, when reaching the specified position, under the action of the control device, the second cover body remains in an unfolded state relative to the first cover body, and will not be folded relative to each other, ensuring the one-time closing of the upper cover structure. When the upper cover structure does not need to be closed, the second cover body is in a free state, which does not affect the folding effect. It is simple and convenient, providing convenience for users.

DETAILED DESCRIPTION

[0050] 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.

[0051] In the description of the present invention, it should be noted that the terms "upper", "inner", "outer", etc. indicate directions or positional relationships 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.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or 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.

[0053] like Figures 1 to 3 As shown, a foldable upper cover structure 1 of the present invention includes a first cover body 11 and a second cover body 12 which can be connected in a relatively foldable manner; it also includes a locking unit 2, which is installed at the relatively folded position of the first cover body 11 and the second cover body 12, and is used to lock and unlock the relative connection state of the first cover body 11 and the second cover body 12, so that the second cover body 12 is respectively in an unfolded state maintained in the extension direction of the first cover body 11 and a free state provided by the gravity of the second cover body 12 and relatively rotating with the first cover body 11; a control device 3 is connected to the locking unit 2, and is used to control the locking and unlocking states of the locking unit 2.

[0054] The control device 3 is mechanically or electrically connected to the locking unit 2 . The control device 3 is an electrical device provided with a switch, which is controlled by the switch or remotely controlled by a user; or it is a mechanical transmission device that controls the unlocking and locking of the locking unit 2 .

[0055] The control device 3 of the present invention can control the two states of locking and unlocking of the locking unit 2, and further control the unfolding and free state of the second cover body 12 of the upper cover structure 1. In the process of closing the upper cover structure 1, it is only necessary to operate the control device 3 to unfold the second cover body 12, prevent the second cover body 12 from folding relative to the first cover body 11, and further realize the one-time closing of the upper cover structure 1, which provides convenience for the user. It can not only give full play to the folding effect of the foldable upper cover structure 1, reduce the occupied space, but also effectively prevent the upper cover structure 1 from failing to be closed in place at one time.

[0056] The control device 3 is an electric control device, which is electrically connected to the locking unit 2. The electric control device can ensure the accuracy of the on and off state of the switch, and can also provide convenience for the user, saving time and effort.

[0057] The device for supplying power to the locking unit 2 is integrated with the electric control device, or can be an independent device installed on the body of the relevant equipment and electrically connected to the electric control device.

[0058] Furthermore, if Figure 3 As shown, the electric control device includes a power supply unit 31 electrically connected to the locking unit 2 for supplying power to the locking unit 2 ; and a switch unit connected to the power supply unit 31 for controlling the on / off of the circuit of the power supply unit 31 .

[0059] The power supply unit 31 can be a micromotor with a power storage function or a power supply installed, or a micromotor electrically connected to an external power supply device, and the external power supply device provides power to the power supply unit 31. The electric control device integrates the switch unit and the power supply unit 31 into an integrated device, which simplifies the relevant structure and reduces the occupied area.

[0060] As an alternative, the foldable upper cover structure 1 of the present invention further comprises a buckle, which is installed on the second cover body 12 and is used for opening and closing the upper cover structure 1; the control device 3 is installed on the buckle.

[0061] The control device 3 of the present invention is installed on the buckle handle, which is convenient for the user to control the control device 3 when the user opens and closes the upper cover structure 1. The user can control the opening and closing of the control device 3 and the upper cover with one hand at the same time, which is simple and convenient for the user to operate.

[0062] The locking unit 2 includes a magnetic component, which is used to provide a magnetic attraction force for the first cover body 11 and the second cover body 12. The locking unit 2 of the present invention includes a magnetic component, so that the first cover body 11 and the second cover body 12 have a certain magnetic attraction force at the relative folding position, and when there is no external force or the external force is less than the magnetic attraction force provided by the magnetic component to the first cover body 11 and the second cover body 12, it can prevent the second cover body 12 from being relatively folded relative to the first cover body 11, thereby preventing the situation that the upper cover structure 1 cannot be closed in place at one time during the process of closing.

[0063] Furthermore, the magnetic component is an electromagnet, and the control device 3 controls the power on and off of the electromagnet.

[0064] The electromagnet is installed on the first cover body 11 and / or the second cover body 12, and the electromagnet is attracted to the metal material or the magnetic information to realize the attraction connection between the first cover body 11 and the second cover body 12, thereby opening the first cover body 11 and the second cover body 12.

[0065] like Figure 1As shown, the electromagnet is installed on the first cover body 11; the control device 3 is the electric control device, the power supply part 31 of the electric control device and the electromagnet are electrically connected through a wire 33, and the position of the second cover body 12 opposite to the electromagnet is made of metal or is provided with a magnet 14.

[0066] Installing the electromagnet on the first cover 11 facilitates the electrical connection between the electromagnet and the electric control device through the wire 33 , simplifies the arrangement of the wire 33 , and reduces interference with the unfolding and folding process of the second cover 12 relative to the first cover 11 .

[0067] The electromagnet is installed outside the first cover 11 or inside the first cover 11; the second cover 12 at a position opposite to the electromagnet is cast from metal, or a metal part is arranged inside the second cover 12 at a position opposite to the electromagnet.

[0068] As an implementation scheme, the electromagnet is installed inside the first cover 11, and a metal piece is provided inside the second cover 12 at a position opposite to the electromagnet. This solution can prevent the metal piece from being exposed to air and water vapor for a long time in the external environment and corroding, and can also prevent the electromagnet from being affected by external forces and bumping, thereby increasing the service life of the electromagnet and reducing the user's living cost.

[0069] As an implementation scheme, Figure 1 and Figure 2 As shown, the electromagnet is a block structure, and is provided in plurality, located outside the first cover body 11 , and evenly distributed along the end surfaces of the relative folding positions of the first cover body 11 and the second cover body 12 , and each electromagnet is electrically connected via a wire 33 .

[0070] Furthermore, if Figure 1 and Figure 2 As shown, the first cover body 11 is provided with a first flange 111 on one side facing the inside of the cover, and the second cover body 12 is provided with a second flange 121 on one side facing the inside of the cover; the first flange 111 and the second flange 121 are hinged at their edges; the electromagnet is installed on the side of the first flange 111 close to the first cover body 11. A metal part is provided inside the second flange 121 at a position opposite to the electromagnet.

[0071] The foldable upper cover structure 1 of the present invention is hinged by the first flange 111 and the second flange 121 so that the two cover surfaces of the second cover body 12 can be in a state of close fit and flush contact end surfaces when the second cover body 12 is unfolded, thereby ensuring the sealing of the upper cover structure 1.

[0072] As an alternative to the above solution, Figure 1 and Figure 2 As shown, the electromagnet is mounted on the first cover 11; the second cover 12 is provided with a magnet 14 at a position opposite to the electromagnet. The electromagnet and the magnet 14 are both block structures, and are provided in plurality, and are respectively mounted on the first flange 111 and the second flange 121, located outside the first flange 111 and the second flange 121, and are evenly distributed along the end surfaces of the first flange 111 and the second flange 121. Each electromagnet is electrically connected through a wire 33, and each magnet 14 corresponds to each electromagnet.

[0073] This solution can provide a strong magnetic attraction for the first cover 11 and the second cover 12, and when the electromagnet is energized, the second cover 12 is ensured to be in a stable relative unfolded state relative to the first cover 11. In addition, since the electromagnet and the magnet are both installed on the outside of the two covers, it is easy to disassemble, replace, and install, and the user can disassemble and assemble them by himself, which is simple and convenient, and improves the applicability of the foldable upper cover structure 1.

[0074] The locking unit 2 of the present invention is in the form of an electromagnet, so that the locking unit 2 has a simple structure, a relatively simple installation method, is easy to produce and process, and has a low production cost. In addition, the electromagnet is relatively common and easy to purchase, and when the electromagnet is damaged, the user can also replace it by himself. The scope of use is wide and the applicability is strong.

[0075] The combined arrangement of the foldable upper cover structure 1, the locking unit 2 and the control device 3 of the present invention can be applied to a variety of devices, and is used to prevent the second cover body 12 from folding relative to the first cover body 11 under the action of gravity when the foldable upper cover structure 1 is covered on the main body of the relevant device, thereby preventing the situation where a one-time covering cannot be achieved.

[0076] like Figure 4 and Figure 5 As shown, the washing device of the present invention has the above-mentioned foldable upper cover structure 1, and also includes a pan seat 4, and at least part of the structure of the control device 3 is installed on the pan seat 4.

[0077] The washing device also includes a hinge part 5, which is installed on the end of the first cover body 11 away from the second cover body 12 and the disc seat 4, and is used to hinge the first cover body 11 and the disc seat 4; the first cover body 11 can rotate around the hinge part 5; at least part of the structure in the control device 3 is installed at the hinge position close to the disc seat 4 and the first cover body 11.

[0078] like Figures 1 to 5As shown, the hinged portion 5 is composed of a rotating member 51 installed on the first cover body 11 and a rotating shaft 52 installed on the disc base 4. The rotating member 51 is provided with a through hole matching the rotating shaft 52. The rotating shaft 52 is inserted into the through hole 511. The rotating member 51 rotates around the rotating shaft 52 to realize the rotation of the first cover body 11 relative to the disc base 4.

[0079] The rotating member 51 and the first cover body 11 are both made of plastic, and the rotating member 51 and the first cover body 11 are integrally formed.

[0080] like Figure 1 and Figure 3 and Figure 5 As shown, the control device 3 includes a power supply part 31 installed on the disc base 4, electrically connected to the locking unit 2, and used to supply power to the locking unit 2; a wire 33, one end of which is connected to the power supply part 31, and the other end passes through the hinge part 5 and is connected to the locking unit 2; a switch part, which is connected to the power supply part 31 and is used to control the on and off of the circuit of the power supply part 31.

[0081] like Figure 3 and Figure 5 As shown, the wire 33 is led out from the end of the power supply part 31, and a wiring hole 511 is also provided on the rotating member 51 of the first cover body 11. The wire 33 passes through the wiring hole 511, and is routed along the inner wall edge of the first cover body 11, and the wire 33 is fixed, and finally connected to the locking unit 2 located at the position where the first cover body 11 and the second cover body 12 are relatively folded, so as to supply power to the locking unit 2. The wire 33 is fixedly arranged on the inner wall edge of the first cover body 11, which can prevent the wire 33 from being touched, ensure the stability of the wire 33, and prevent the wire 33 from contacting the washing water in the washing chamber, causing leakage, power failure and other dangerous conditions.

[0082] The power supply unit 31 can be a micro motor with a power storage function or a power supply installed, or a micro motor electrically connected to the washing device, and the washing device body provides power to the power supply unit 31. The control device 3 integrates the switch unit and the power supply unit 31 into an integrated device, which simplifies the relevant structure and reduces the occupied area on the washing device.

[0083] The switch state of the switch part can be manually controlled by a user, automatically controlled by the body of the washing device, controlled by a control program of the washing device, or remotely controlled by a user.

[0084] Furthermore, if Figure 3 and Figure 5 As shown, the switch portion includes two conductive contact pieces 32, one end of the two conductive contact pieces 32 is connected to the power supply portion 31, and the other end of at least one of the conductive contact pieces 32 is a movable end.

[0085] like Figure 2 and Figure 3 and Figure 5 As shown, a toggle unit 512 is installed on the first cover body 11 for toggling the movable end of the conductive contact piece 32 to connect and disconnect the two conductive contact pieces 32 .

[0086] like Figure 2 and Figure 3 and Figure 5 As shown, the toggle unit 512 is installed on the rotating member 51. Preferably, the toggle unit 512 is integrally formed with the rotating member 51 and is formed by extending the rotating member 51 to one side of the disk base 4. The two conductive contact pieces 32 are arranged in parallel up and down, and the other end of the conductive contact piece 32 located above is a movable end, which is toggle-moved by the toggle unit 512.

[0087] As an implementation scheme, one end of the lower conductive contact piece 32 away from the power supply part 31 is fixed at a hinged position of the disk base 4 close to the first cover body 11. During the closing process of the first cover body 11, the movable end of the upper conductive contact piece 32 moves with the first cover body 11, or the movable end of the upper conductive contact piece 32 is moved by the first cover body 11 after the first cover body 11 reaches a specified position, and moves with the first cover body 11, and is connected and disconnected with the end of the lower conductive contact piece 32 away from the power supply part 31 under the action of the first cover body 11.

[0088] The first cover body 11 has the following two states: in the first state, the angle between the first cover body 11 and the disk base 4 is less than a set value, the toggle unit 512 toggles the movable end of the conductive contact 32, the two conductive contacts 32 touch, and the control device 3 is powered on; in the second state, the angle between the first cover body 11 and the disk base 4 is greater than or equal to a set value, the other ends of the two conductive contacts 32 are disconnected, and the control device 3 is powered off.

[0089] As an implementation scheme, the setting value of the included angle between the first cover body 11 and the disc base 4 is 40°.

[0090] Working principle: when the upper cover structure 1 is in the open state, the two conductive contacts 32 are in the disconnected state, the power supply part 31 cannot supply power to the locking unit 2, the locking unit 2 is unlocked, and the second cover body 12 is in a free state relative to the first cover body 11. Under the action of gravity, it can be folded relative to the first cover body 11. The upper cover structure 1 is in the folded state to save space occupied by the washing equipment.

[0091] During the process of closing the upper cover structure 1, the angle between the first cover body 11 and the disk seat 4 gradually decreases until the angle between the two is less than the set value, the two conductive contacts 32 touch each other, the circuit of the control device 3 is turned on, the power supply part 31 supplies power to the locking unit 2 through the wire 33, and the locking unit 2 locks the relative connection state between the first cover body 11 and the second cover body 12, so that the second cover body 12 is in an unfolded state relative to the first cover body 11, preventing the second cover body 12 from folding relative to the first cover body 11, until the upper cover structure 1 is completely covered on the disk seat 4, thereby ensuring that the upper cover structure 1 is covered on the disk seat 4 at one time.

[0092] During the process of opening the upper cover structure 1, the angle between the first cover body 11 and the disk seat 4 gradually increases until the angle between the two reaches a set value, the two conductive contacts 32 disconnect, the control device 3 is disconnected, the power supply part 31 cannot supply power to the locking unit 2 through the wire 33, the locking unit 2 is unlocked, and the second cover body 12 is in a free state and can be folded relative to the first cover body 11, so that the upper cover structure 1 is in a folded state.

[0093] The switch state of the control device 3 of the present invention is determined by the relative position of the first cover body 11 and the tray base 4, and the user does not need to manually operate the control device 3, and the switch part of the control device 3 can be automatically opened and closed, which is simple and convenient. In addition, in the process of closing the upper cover structure 1, when reaching the specified position, under the action of the control device 3, the second cover body 12 can be automatically unfolded relative to the first cover body 11, and will not be relatively folded, ensuring the one-time closing of the upper cover structure 1. When the upper cover structure 1 does not need to be closed, the second cover body 12 is in a free state, which does not affect the folding effect. It is simple and convenient, providing convenience for users.
