Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dishwashers, in particular to a washing machine used for washing tableware, fruits and vegetables. Background Art
[0002] Existing dishwashers, for front-opening dishwashers, usually use a manual door opening structure. The dishwasher door is connected by a hinge and must be able to hover at a large angle. Otherwise, the door will fall freely and injure the customer.
[0003] Chinese patent application CN220344365U, titled "A Household Appliance" (application number: CN202322307324.7), discloses a door hinge structure. A pull cord and an elastic member are connected between the door hinge and the dishwasher body. The rear end of the elastic member is connected to the dishwasher body, while the front end is attached to one end of the pull cord. The other end of the pull cord passes through multiple pulleys and then hooks onto the door hinge.
[0004] With this solution, an elastic element is typically used to store a certain amount of energy, keeping the pull cord stretched and securely locked. This results in the user needing to exert considerable force to initially open the door. Inertia causes the door to rapidly open wide, and the hot steam from the washing chamber can hit the user, potentially causing burns and a negative user experience. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a cleaning machine which saves effort when opening the door and can temporarily limit the door at a specific opening to allow hot air to be discharged, in response to the current status of the existing technology.
[0006] The technical solution adopted by the present invention to solve the above technical problems is:
[0007] A cleaning machine comprises a box body, a door body, a hinge and a door lock structure, wherein the front side of the box body is provided with an opening, and the bottom of the door body is rotatably arranged at the bottom edge of the opening on the front side of the box body through a hinge, and the door lock structure is arranged at the top of the box body and the door body, and is used to lock or unlock the two, and also includes an ejection structure that can eject the door body outward in the unlocked state and a limiting structure that temporarily limits the position of the door body when the door opening is A. The ejection structure is arranged between the top of the box body and the top of the door body, and the limiting structure is arranged on the outer side wall of the box body and cooperates with the hinge to limit the position.
[0008] With the above structure, when the door needs to be opened after washing is completed, the door lock structure contacts the lock between the box body and the door body, and the ejection structure will push the door body outward, saving effort for the user to open the door; when the door body is opened at an angle A, the limiting structure will temporarily limit the position of the door body, so that the door body is maintained at a smaller opening A. At this time, the hot steam in the washing chamber can be discharged through the open gap of the door body, and will not burn the user due to excessive opening. It is easy to use and is conducive to improving the user experience.
[0009] Preferably, the ejection structure is an elastic component provided at the corner of the front side wall of the box body, and the diameter of the elastic component gradually decreases from the back to the front. With this structure, the volume of the elastic component can be reduced in the compressed state, thereby improving the sealing between the box body and the door body.
[0010] Preferably, the elastic assembly includes a first elastic member and an elastic sleeve. The first elastic member is a linear spring with a diameter that gradually decreases from rear to front. The elastic sleeve wraps around the first elastic member and conforms to its shape. This structure further reduces the volume of the elastic assembly in its compressed state.
[0011] Preferably, the elastic sleeve comprises a plurality of radially connected elastic segments, each of which increases in diameter from front to back. When the elastic sleeve is compressed, the front elastic segment is folded and concealed within the rear elastic segment. This structure improves the elastic assembly's telescopic stability and reliability.
[0012] Preferably, the limiting structure includes an adjustment component and a limiting member. The adjustment component is provided on the side of the box body and connected to the hinge for controlling the hovering of the door body. The adjustment component includes a pull rope that can be connected to the hinge and an elastic member that provides tension for the pull rope. The pull rope includes a first section connected to the hinge and a second section connected to the elastic member. When the door body is opened at an angle less than or equal to A relative to the door body, the tension on the first section is less than the outward opening force of the door body under gravity. When the door body is opened at an angle greater than A relative to the door body, the tension on the first section is greater than or equal to the outward opening force of the door body under gravity. The limiting member is provided on the side of the box body, behind the hinge, for resisting against the rear end of the hinge when the door body is opened at A degrees, thereby temporarily limiting the door body.
[0013] With the above structure, when the door needs to be opened after washing is completed, the ejection structure will first push the door body outward, and then the door body can automatically open to angle A under the action of the weight of the door body without the need for user operation, so that the hot steam in the washing chamber can be discharged. The user can then pull the door handle by hand to continue to open the door body angle. Since the tension of the pull rope begins to take effect when the door opening is greater than A, the door body can still hover at any position, making the door opening process more labor-saving and convenient to use.
[0014] Preferably, the side of the door is provided with a stopper located behind the hinge and capable of abutting against the rear end of the hinge when the door is opened to degree A, thereby temporarily limiting the door's position. This structure limits the door's free opening angle to within degree A, preventing excessive opening from causing steam to escape over a large area and burn the user.
[0015] Preferably, the stopper is elastic. When the door is closed, the rear end of the hinge is located below the stopper. When the door is opened at an angle A, the rear end of the hinge is still located below the stopper and contacts the stopper. When the door is opened at an angle greater than A, the rear end of the hinge elastically squeezes the stopper and then jumps above the stopper. This structure allows the door to be temporarily stopped at the opening angle A without affecting the user's ability to continue opening the door, thus saving the user effort.
[0016] Preferably, the stopper comprises a horizontal plate extending forward and backward, with the front end of the plate bent downward and forward to form an L-shaped elastic buckle. When the stopper and the hinge are in a restrained position, the rear end of the hinge rests against the elastic buckle. This structure provides good resistance when the hinge is in the state of being restrained, and when the door needs to be opened further, it saves the user effort.
[0017] Preferably, the horizontal side of the limiter is provided with a side plate for locking it to the side of the box, and the side plate is provided with a locking hole. This structure facilitates locking the limiter to the side of the box, and can be locked by screws, which is easy to install.
[0018] Preferably, the front end of the hinge is connected to the side edge of the door body, the middle part of the hinge is rotatably connected to the outer wall of the box body, and the rear end of the hinge is provided with a hook, and the end of the first section of the pull rope is hung on the hook.
[0019] Preferably, the hook is U-shaped, with the rear height of the U-shaped structure being less than the front height. When the stopper and the hinge are mutually restrained, the upper end of the rear side of the hook abuts against the bottom of the stopper. This structure provides good resistance when the door is in the hinge state, and saves the user effort when the door needs to be opened further.
[0020] Preferably, a base is provided at the bottom of the box, and the adjustment component is provided on the outer side wall of the base and below the hinge.
[0021] Preferably, the elastic member is arranged horizontally with its front end connected to the front edge of the base. The first end of the second section of the pull cord is connected to the rear end of the elastic member. A first pulley is provided on the side wall of the base near the rear edge, and a second pulley is provided on the side wall of the base near the top of the elastic member. The second section of the pull cord passes around the first and second pulleys from bottom to top, forming two relatively parallel parts. The first section of the pull cord extends obliquely from the bottom of the second pulley toward the hinge. This structure facilitates the use of the elastic member to achieve hovering of the door body.
[0022] Preferably, a door lock structure is provided between the front edge of the top of the box body and the top edge of the door body, which can lock or unlock the two. The door lock is provided here so that the door body can be opened by its own gravity when unlocked.
[0023] Compared with the prior art, the advantages of the present invention are: when the door needs to be opened after washing is completed, the door lock structure contacts the lock between the box body and the door body, and the ejection structure will push the door body outward, saving effort for the user to open the door; when the door body is opened at an angle A, the limiting structure will temporarily limit the position of the door body, so that the door body is maintained in a smaller opening state A. At this time, the hot steam in the washing chamber can be discharged through the open gap of the door body, and will not burn the user due to excessive opening. It is easy to use and is conducive to improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0031] like Figures 1 to 6As shown, the cleaning machine of this embodiment includes a box body 1, a door body 2, a hinge 3 and a door lock structure 7. An opening 11 is provided on the front side of the box body 1. The bottom of the door body 2 is rotatable at the bottom edge of the opening 11 on the front side of the box body 1 through the hinge 3. The door lock structure 7 is provided on the top of the box body 1 and the door body 2 and is used to lock or unlock the two. It also includes an ejection structure that can eject the door body 2 outward in the unlocked state and a limiting structure that temporarily limits the position of the door body 2 when the door body 2 is open to A. The ejection structure is provided between the top of the box body 1 and the top of the door body 2, and the limiting structure is provided on the outer wall of the box body 1 and cooperates with the hinge 3 to limit the position.
[0032] The ejection structure is an elastic component 8 provided at the corner of the front wall of the box body 1. The diameter of the elastic component 8 gradually decreases from the back to the front. With the above structure, the volume of the elastic component can be reduced in the compressed state, thereby improving the sealing between the box body and the door body.
[0033] The elastic assembly 8 comprises a first elastic member 81 and an elastic sleeve 82. The first elastic member 81 is a linear spring with a diameter that gradually decreases from rear to front. The elastic sleeve 82 wraps around the outer periphery of the first elastic member 81 and conforms to the shape of the first elastic member 81. This structure further reduces the volume of the elastic assembly in its compressed state.
[0034] The elastic sleeve 82 comprises a plurality of radially connected elastic segments 821, each of which increases in diameter from front to back. When the elastic sleeve 82 is compressed, the front elastic segments 821 fold and hide within the rear elastic segments. This structure improves the elastic assembly's telescopic stability and reliability.
[0035] In this embodiment, the limiting structure includes an adjustment assembly 4 and a limiting member 5. The adjustment assembly 4 is located on the side of the housing 1 and connected to the hinge 3, and is used to control the hovering of the door body 2. The adjustment assembly 4 includes a pull rope 41 that can be connected to the hinge 3 and an elastic member 42 that provides tension to the pull rope 41. The pull rope 41 includes a first section 411 connected to the hinge 3 and a second section 412 connected to the elastic member 42. When the door body 2 is opened at an angle less than or equal to A relative to the door body 2, the tension on the first section 411 is less than the outward opening force of the door body 2 under gravity. When the door body 2 is opened at an angle greater than A relative to the door body 2, the tension on the first section 411 is greater than or equal to the outward opening force of the door body 2 under gravity. The limiting member 5 is located on the side of the housing 1, behind the hinge 3, and is used to abut against the rear end of the hinge 3 when the door body 2 is opened to degree A, thereby temporarily limiting the door body 2.
[0036] In this embodiment, when the door needs to be opened after washing is completed, the ejection structure first pushes out the door body 2, and then the door body 2 can automatically open to angle A under the action of gravity without the user pulling the door body 2, so that the hot steam in the washing chamber can be discharged. The user then pulls the door handle by hand to continue to open the door body 2. Since the tension of the pull rope 41 begins to take effect when the opening angle of the door body 2 is greater than A, the door body 2 can still hover at any position, making the door opening process more labor-saving and convenient to use, which is conducive to improving the user experience.
[0037] The stopper 5 is made of plastic and is elastic. When the door is closed, the rear end of the hinge 3 is located below the stopper 5. When the door is opened at an angle A, the rear end of the hinge 3 is still located below the stopper 5 and contacts the stopper 5. When the door is opened at an angle greater than A, the rear end of the hinge 3 elastically squeezes the stopper 5 and jumps above the stopper 5. The above structure can temporarily limit the door body 2 to the opening angle A without affecting the user's continued opening of the door body 2, thus saving the user effort.
[0038] The stopper 5 includes a horizontal plate 51 extending forward and backward. The front end of the horizontal plate 51 is bent downward and forward to form an L-shaped elastic buckle 52. When the stopper 5 and the hinge 3 are in a restrained state, the rear end of the hinge 3 rests under the elastic buckle 52. This structure provides good resistance to the hinge 3 and saves the user effort when the door body 2 needs to be opened further.
[0039] The horizontal side of the limiter 5 is provided with a side plate 53 for locking it to the side of the box body 1. The side plate 53 is provided with a locking hole. This structure facilitates locking the limiter 5 to the side of the box body 1 and can be locked by screws, making it easy to install.
[0040] The front end of the hinge 3 is connected to the side edge of the door body 2, the middle part of the hinge 3 is rotatably connected to the outer wall of the box body 1, and the rear end of the hinge 3 is provided with a hook 31, and the end of the first section 411 of the pull rope 41 is hung on the hook 31.
[0041] The hook 31 is U-shaped, with the rear side of the U-shaped structure being shorter than the front side. When the stopper 5 and the hinge 3 are restrained against each other, the upper end of the rear side of the hook 31 abuts against the bottom of the stopper 5. This structure provides good resistance to the hinge 3 and saves the user effort when the door body 2 needs to be opened further.
[0042] A base 6 is provided at the bottom of the box body 1 , and the adjustment component 4 is provided on the outer side wall of the base 6 and below the hinge 3 .
[0043] The elastic member 42 is arranged horizontally, with its front end connected to the front edge of the base 6. The first end of the second section 412 of the pull cord 41 is connected to the rear end of the elastic member 42. A first pulley 43 is provided on the side wall of the base 6 near the rear edge, and a second pulley 44 is provided on the side wall of the base 6 near the top of the elastic member 42. The second section 412 of the pull cord 41 passes from bottom to top around the first pulley 43 and the second pulley 44, forming two relatively parallel parts. The first section 411 of the pull cord 41 extends obliquely from the bottom of the second pulley 44 toward the hinge 3. This structure facilitates the use of the elastic member 42 to achieve the hovering of the door body 2.
[0044] A door lock structure 7 that can lock or unlock the two is provided between the front edge of the top of the box body 1 and the top edge of the door body 2. The door lock is arranged here so that the door body 2 can be opened by its own gravity when unlocked.
[0045] In this embodiment, when the door needs to be opened after washing is completed, the door lock structure 7 contacts the lock of the box body 1 and the door body 2, and the ejection structure will push the door body 2 outward, saving the user effort to open the door; when the door body 2 is opened to an angle A, the limiting structure will temporarily limit the position of the door body 2, so that the door body 2 is maintained at a smaller opening A. At this time, the hot steam in the washing chamber can be discharged through the open gap of the door body 2, and will not burn the user due to excessive opening. It is easy to use and is conducive to improving the user experience.
[0046] In the specification and claims of the present invention, directional terms such as "front," "back," "up," "down," "left," "right," "side," "top," and "bottom" are used to describe various exemplary structural parts and components of the present invention. However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different orientations, these directional terms are intended for illustrative purposes only and should not be construed as limiting. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
