Even if there is slight wear between the door body hook 71 and the lock hook 4, it will not affect its locking of the door panel 7, thereby avoiding the problem of loose locking caused by long-term use of the door panel locking device in the prior art; at the same time, the lock hook device of the present application has a simple structure, is easy to control, and can improve the efficiency and convenience of locking the door panel 7.

[0034] Example 1

[0035] like Figure 1-Figure 5 As shown, the present application provides a lock hook device for door panel control, including a cover plate 1, a decorative panel 6 and a door panel 7. A notch for placing the door panel 7 is provided in the decorative panel 6. The door panel 7 is hinged to the decorative panel 6, and the door panel 7 can rotate along the hinge axis 8. In the present application, it is set that the door panel 7 can rotate toward the front of the decorative panel 6. A door body hook 71 is provided in the door panel 7. The door body hook 71 is used to cooperate with the lock hook 4 in the cover plate 1. When the two are fixed together, the door panel 7 is fixed. When the two are separated, the door panel 7 can be opened.

[0036] Cover plate 1 is fixed to the back of decorative panel 6; the back here refers to the side opposite the front of decorative panel 6. We define the side of cover plate 1 fixed to decorative panel 6 as the front of cover plate 1, and the side of cover plate 1 away from decorative panel 6 as the back of cover plate 1. Cover plate 1 is equipped with a drive member and a lock hook 4, the end of which is compatible with the door hook 71. The drive member can drive the lock hook 4 to slide along the plane of cover plate 1, so that the end of the lock hook 4 is fixed to or released from the door hook 71.

[0037] Specifically, in the present application, the sliding direction of the lock hook 4 is parallel to the plane of the cover plate 1, and the end of the lock hook 4 protrudes from the cover plate 1 and can be adapted to connect with the door hook 71. In the present application, the driving member can be located at any position of the lock hook 4, as long as it can drive the lock hook 4 to move toward or away from the door hook 71.

[0038] As a specific embodiment, the driving member in this application is a button 2, which is located at the front end of the lock hook 4. The front end here refers to the other end opposite to the end of the lock hook 4. When the button 2 is pressed or released, it can drive the lock hook 4 to slide.

[0039] In this application, the moving direction of the button 2 can be perpendicular to the plane where the cover 1 is located, or it can be the same as the sliding direction of the lock hook 4. Figure 1 and Figure 2 As shown, the movement direction of the button 2 can be set to be perpendicular to the plane where the cover plate 1 is located. Specifically, a button through hole is provided in the cover plate 1, and the button 2 passes through the button through hole and can slide along a plane perpendicular to the plane where the cover plate 1 is located. At the same time, the button 2 is located at the top of the cover plate 1, and the end of the button 2 is an inclined surface facing the lock hook 4, and the top of the lock hook 4 is adapted to the inclined surface of the end of the button 2. When the button 2 is not pressed, the button 2 and the top of the lock hook 4 do not contact; when the button 2 is pressed, the end of the button 2 abuts against the top of the lock hook 4. At the same time, since the abutment between the two is an adapted inclined surface, the button 2 will push the lock hook 4 to slide in the direction away from the button 2, thereby causing the end of the lock hook 4 to fall off the door body hook 71. At this time, pulling the door panel 7 will cause the door panel 7 to rotate along the hinge shaft 8, thereby realizing the opening of the door panel 7.

[0040] In order to facilitate the resetting of the button 2, a button spring 21 is nested on the outside of the button 2 in this application, one end of the button spring 21 abuts against the front end of the button 2, and the other end of the button spring 21 abuts against the front face of the cover 1. The front end of the button 2 can be set to a larger cross-section to facilitate the pressing operation and to fix the button spring 21.

[0041] In the present application, the shape of the end of the button 2 that matches the top of the lock hook 4 can be an inclined surface or an arc surface, etc. It is necessary to ensure that when the button 2 pushes the lock hook 4 in a direction perpendicular to the cover 1, the lock hook 4 can move in a direction away from the button 2 under the action of the driving force.

[0042] In this application, a slide rail 43 is provided on the back of the cover plate 1, and the lock hook 4 is positioned within this rail. The lock hook 4 slides vertically, with the end of the lock hook 4 protruding from the cover plate 1 and facing toward the door panel 7. To facilitate the reset of the lock hook 4, a lock hook spring 41 is provided within the lock hook 4 and nested within its outer portion. One end of the lock hook spring 41 abuts against the lock hook 4, while the other end is fixedly connected to the cover plate 1. When the lock hook 4 is in its initial state—that is, when the lock hook 4 is not actuated by the button 2—the lock hook spring 41 is in its normal extended state. When the lock hook 4 slides downward under the action of the button 2, the lock hook spring 41 is compressed because one end of the lock hook spring 41 is fixed and the other end moves with the lock hook 4. When the button 2 is reset, the lock hook 4 quickly resets under the elastic force of the lock hook spring 41.

[0043] like Figure 1 and Figure 2As shown, a notch can be provided in the cover plate 1. At the same time, a connecting rod 42 with a nested spring is provided on the side of the lock hook 4. The lock hook spring 41 is nested on the outside of the connecting rod 42. A corresponding sliding groove for the connecting rod 42 is provided below the notch to ensure that the connecting rod 42 can slide with the lock hook 4. A slide rail 43 is provided below the notch, and the lock hook 4 slides along the slide rail 43. In the installed structure, one end of the lock hook spring 41 abuts against the top of the connecting rod 42, and the other end abuts against the cover plate 1 at the notch.

[0044] In the present application, the end of the lock hook 4 and the end of the door body hook 71 are respectively provided with grooves facing opposite directions. When the two grooves are engaged, the lock hook 4 and the door body hook 71 are connected together to achieve locking of the door panel.

[0045] Specifically, when the lock hook 4 slides along the vertical direction, the end of the lock hook 4 is provided with a lock hook groove opening upward, and the end of the door body hook 71 is provided with a hook groove opening downward. When the lock hook 4 slides downward along the vertical direction, the lock hook groove is disengaged from the door body hook 71, and the door panel can be opened at this time; after the door panel is opened, the lock hook 4 is reset under the action of the lock hook spring 41, and the lock hook 4 is reset upward along the vertical direction.

[0046] Specifically, the hook groove at the end of the lock hook 4 has an upwardly inclined sidewall, and the hook groove at the end of the door hook 71 has a downwardly inclined sidewall. When the door panel is closed, the lock hook 4 has been reset under the action of the lock hook spring 41. At this time, the downwardly inclined surface of the hook groove at the end of the door hook 71 adapts and abuts the upwardly inclined sidewall of the lock hook groove. At the same time, the hook groove pushes the lock hook groove downward until the lock hook groove engages with the hook groove, thereby locking the door panel 7.

[0047] like Figure 1 As shown, the lock hook groove at the end of the lock hook has an upward inclined side wall, which means that the side wall of the lock hook groove close to the door panel is an inclined surface, and the inclined surface in the side wall faces upward; the side wall here refers to the smaller side wall close to the door panel in the lock hook groove, and the larger side wall away from the door panel is the lock hook body located in the cover plate.

[0048] like Figure 5 The hook groove at the end of the door hook 71 has a downwardly inclined sidewall, which means that the sidewall of the hook groove close to the cover plate is an inclined surface, and the inclined surface of the sidewall faces downward. In addition, the inclined sidewall of the hook groove is adapted to the inclined sidewall of the lock hook groove.

[0049] The reason why the side walls of the hook groove and the lock hook groove adjacent to each other are configured as inclined surfaces in this application is to facilitate automatic locking of the door panel. When the door panel is in the open state and needs to be locked, the door panel 7 drives the hook 71 to rotate toward the cover plate 1 until the hook abuts the bottom of the lock hook. At this time, the inclined side wall of the hook groove abuts the inclined side wall of the lock hook groove. The door panel drives the hook to continue moving toward the lock hook. The force acting on the inclined side wall of the hook groove causes the lock hook to move downward until the lock hook 4 moves below the inclined side wall of the door hook groove and then rises under the action of the lock hook spring 41 to engage the door hook 71. In this way, when the door panel 7 is changed from the open state to the locked state, there is no need to use a driving member to drive the lock hook downward. The lock hook and the hook can be automatically engaged by virtue of the hook groove and the inclined side wall of the lock hook groove.

[0050] As a specific embodiment, in this application, a baffle 51 is further provided on the back of the cover 1. The baffle 51 is connected to the baffle driver 5, which can mobilize the baffle 51 to move toward or away from the button through-hole. The function of the baffle 51 is to block the button through-hole when the door panel does not need to be opened, ensuring that the button 2 does not contact the lock hook 4, thereby preventing accidental contact.

[0051] Specifically, a baffle slide 52 is provided on the back of the cover 1. The baffle 51 can be connected to the baffle driver 5, which can drive the baffle 51 to slide in the baffle slide 52 in a direction toward or away from the button through-hole. The extension direction of the baffle slide 52 is perpendicular to the sliding direction of the lock hook 4. The baffle driver 5 can be specifically a telescopic motor. When the telescopic motor is extended, the baffle 51 just blocks the button through-hole, at this time, the button 2 cannot abut against the lock hook 4. When the telescopic motor is retracted, the baffle 51 is located to the side of the button through-hole. When the button 2 is pressed, the button 2 can abut against the lock hook 4 and push the lock hook 4 to slide.

[0052] As a specific embodiment, in order to facilitate the opening of the door panel 7, a top cap through-hole is further provided in the cover plate 1 of the present application. The end of the top cap 3 passes through the top cap through-hole and is fixed to the back of the cover plate 1, and the front end of the top cap 3 abuts against the door panel 7. A top cap spring 31 is nested on the outside of the top cap 3, one end of the top cap spring 31 abuts against the front end of the top cap 3, and the other end of the top cap spring 31 abuts against the front of the cover plate 1. The front end of the top cap 3 of the present application abuts against the door panel 7. When the door panel 7 is in a locked state, the top cap spring 31 is in a compressed state. When the lock hook 4 is disengaged from the door body hook 71, under the elastic force of the top cap spring 31, the front end of the top cap 3 generates a thrust on the door panel 7. This thrust is exactly consistent with the opening direction of the door panel 7, causing the door panel 7 to open.

[0053] As a specific embodiment. Figure 3-Figure 6The diagram shown is a diagram from the back of the cover 1 looking toward the door panel 7, that is, the door panel 7 is rotated away from the inside of the paper. Figure 3 and Figure 5 This is a schematic diagram of the angle from the inside of the drum looking outward. Figure 6 This is a schematic diagram from the perspective of looking from the outside of the drum to the inside. Since the cover plate is set on the back of the decorative plate, the appearance of the structure of this application is neat and elegant, which improves the appearance of the washing machine.

[0054] Furthermore, to secure the cover plate 1 to the decorative panel 6, the decorative panel 6 is provided with a cover plate screw column 61, a motor mounting slot 62, and a top cap slot 63. When installing the cover plate 1, it is only necessary to secure the cover plate 1 to the cover plate screw column 61, secure the baffle driver 5 to the motor mounting slot 62, and place the top cap 3 in the top cap slot 63. The top cap slot 63 extends through the decorative panel 6, such that the front end of the top cap 3 located in the top cap slot 63 abuts the door panel 7. There may be multiple cover plate screw columns 61 to facilitate securing the top and bottom ends of the cover plate 1. The cover plate screw column 61 that matches the top end of the cover plate 1 is secured to the top end of the door panel notch in the decorative panel 6, while the cover plate screw column 61 that matches the bottom end of the cover plate 1 is secured to the position of the decorative panel 6 that coincides with the door panel notch. Specifically, a decorative panel connector that coincides with the door panel 7 may be provided at the door panel notch to secure the cover plate screw column 61 that matches the bottom end of the cover plate 1.

[0055] In the present application, an observation window is also provided in the door panel 7, and transparent glass can be provided at the position of the observation window.

[0056] Example 2

[0057] The present application provides a washing machine, including the lock hook device of embodiment 1, and at the same time, the decorative plate 6 is located in the washing machine housing, and when the door panel 7 is closed, the lock hook 4 cooperates with the door hook 71 to lock the door panel 7. Figure 7 As shown, after the wash cycle begins, the telescopic motor pushes the baffle 51 forward to the position of button 2, blocking it. At this point, button 2 is not in use, preventing the door panel from opening during operation. When the wash cycle is paused or completed, the washing system stops, and the telescopic motor drives the baffle 52 to retract to its initial position, making way for button 2. Now, button 2 is available and can be pressed to open the door panel. The specific principles for opening and locking the door panel are described in the embodiments and will not be detailed here.

[0058] It is understandable that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention.
