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 adopt a manual door opening structure. The dishwasher door is connected by hinges and can be suspended at any angle. Otherwise, the door will fall freely and injure customers.

[0003] The Chinese patent "A Household Appliance" (application number: CN220344365U) with authorization announcement number CN220344365U discloses a hinge structure of a door body. A pull rope 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, and the front end is hung on one end of the pull rope. The other end of the pull rope is hooked to the door hinge after passing through multiple pulleys in sequence.

[0004] When adopting the above solution, an elastic member is usually provided to store a certain amount of energy to keep the pull rope in a stretched state. However, the energy stored in the elastic member directly acts on the door hinge to hinder the opening of the door. The user needs a greater force to open the door, which seriously affects the user experience. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cleaning machine which can save effort when opening a door body and can hover at any position without affecting the door opening process, in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] A cleaning machine comprises a casing, a door, a hinge and an adjusting assembly, wherein an opening is arranged on the front side of the casing, and the bottom of the door is rotatably arranged at the bottom edge of the opening on the front side of the casing through a hinge, the adjusting assembly is arranged on the side of the casing and connected to the hinge for controlling the hovering of the door, the adjusting assembly comprises a pull rope connectable to the hinge and an elastic member providing tensioning force for the pull rope, the pull rope comprises a first section connected to the hinge and a second section connected to the elastic member, when the door is opened at an angle less than or equal to A relative to the door body, the tensioning force on the first section is less than the outward opening force of the door under gravity, and when the door is opened at an angle greater than A relative to the door body, the tensioning force on the first section is greater than or equal to the outward opening force of the door under gravity.

[0008] With the above structure, when the door needs to be opened after washing, the user does not need to pull the door body forcefully. The door body can automatically open to an angle A under the action of its own gravity to allow the hot steam in the washing cavity to escape. Then the user can pull the door handle to further open the door body. Since the tension of the pull rope starts to act when the opening angle of the door body 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, which is beneficial to improving the user experience.

[0009] Preferably, a limiting member is provided on the side of the cabinet body behind the hinge and can abut against the rear end of the hinge when the door body is opened by an angle A to temporarily limit the door body. With the above structure, the freely openable angle of the door body is limited within angle A, avoiding large-area steam ejection and burning the user due to excessive opening.

[0010] Preferably, the limiting member is elastic. In the closed state of the door, the rear end of the hinge is located below the limiting member. When the opening angle is A, the rear end of the hinge is still located below the limiting member and abuts against it. When the opening angle is greater than A, the rear end of the hinge elastically presses the limiting member and jumps above the limiting member. With the above structure, while being able to temporarily limit the door body at an opening of A, it does not affect the user to continue opening the door body, making the user operation labor-saving.

[0011] Preferably, the limiting member includes a horizontal plate extending forward and backward. The front end of the horizontal plate is bent downward and forward to form an L-shaped elastic buckle. When the limiting member and the hinge are in a limiting state, the rear end of the hinge abuts against the lower part of the elastic buckle. This structure provides better resistance when the hinge is in a certain state, and makes the user operation labor-saving when the door body needs to be further opened.

[0012] Preferably, a side plate for locking it to the side of the cabinet body is provided on the side of the horizontal plate of the limiting member, and a locking hole is provided on the side plate. This structure facilitates locking the limiting member to the side of the cabinet body, and can be locked by screws, which is convenient for installation.

[0013] Preferably, the front end of the hinge is connected to the edge of the side of the door body, the middle part of the hinge is rotatably connected to the outer side wall of the cabinet body, and a hook is provided at the rear end of the hinge. The end of the first section of the pull rope is hung on the hook.

[0014] Preferably, the hook has a U-shaped structure, and the height of the rear side of the U-shaped structure is less than that of the front side. When the limiting member and the hinge are in a mutually limiting state, the upper end of the rear side of the hook abuts against the bottom of the limiting member. This structure provides better resistance when the hinge is in a certain state, and makes the user operation labor-saving when the door body needs to be further opened.

[0015] Preferably, a base is provided at the bottom of the cabinet body, and the adjusting component is arranged on the outer side wall of the base and below the hinge.

[0016] Preferably, the elastic member is arranged horizontally and its front end is connected to the front edge of the base. The first end of the second section of the drawstring 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 above the elastic member. The second section of the drawstring bypasses the first pulley and the second pulley from bottom to top to form two relatively parallel parts, and the first section of the drawstring extends obliquely from the bottom of the second pulley to the hinge. The above structure facilitates the use of the elastic member to achieve the hovering of the door body.

[0017] Preferably, a door lock structure capable of locking or unlocking the front edge of the top of the box body and the top edge of the door body is provided. Setting the door lock here facilitates the door body to be opened by its own gravity in the unlocked state.

[0018] Compared with the prior art, the advantages of the present utility model are as follows: When the door needs to be opened after the washing is completed, the user does not need to pull the door body forcefully. The door body can automatically open to an angle A under the action of its own gravity to discharge the hot steam in the washing cavity. Then, the user can continue to open the door body to a larger angle by pulling the door handle. And since the tension of the drawstring starts to act when the opening degree of the door body 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, which is beneficial to improving the user experience.

[0024] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] As Figures 1 to 5As shown, the cleaning machine of this embodiment includes a casing 1, a door body 2, a hinge 3 and an adjusting assembly 4. An opening 11 is provided on the front side of the casing 1. The bottom of the door body 2 is rotatably arranged at the bottom edge of the opening 11 on the front side of the casing 1 through the hinge 3. The adjusting assembly 4 is arranged on the side of the casing 1 and connected to the hinge 3 for controlling the hovering of the door body 2. The adjusting assembly 4 includes a pull rope 41 that can be connected to the hinge 3 and an elastic member 42 that provides tension for 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.

[0026] By adopting the above structure, when the door needs to be opened after washing, the user does not need to pull the door body 2 hard. The door body 2 can automatically open to angle A under the action of gravity to allow the hot steam in the washing chamber to be discharged. Then the user can pull 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, thereby making the door opening process more labor-saving and convenient to use, which is conducive to improving the user experience.

[0027] The side of the box body 1 is provided with a stopper 5 located at the rear side of the hinge 3 and capable of abutting against the rear end of the hinge 3 when the door body 2 is opened to a degree A, thereby temporarily limiting the position of the door body 2. With the above structure, the angle at which the door body 2 can be freely opened is limited to within a degree A, thereby preventing the steam from being ejected over a large area and burning the user due to excessive opening.

[0028] The stopper 5 is made of plastic and is elastic. In the closed state, the rear end of the hinge 3 is located below the stopper 5. When the door opening angle is A, the rear end of the hinge 3 is still located below the stopper 5 and abuts against the stopper 5. When the door opening angle is greater than A, the rear end of the hinge 3 elastically squeezes the stopper 5 and then jumps above the stopper 5. With the above structure, the door body 2 can be temporarily limited to the opening degree A without affecting the user to continue to open the door body 2, which saves the user effort.

[0029] The limiting member 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, and when the limiting member 5 and the hinge 3 form a limiting state, the rear end of the hinge 3 abuts under the elastic buckle 52. This structure provides good resistance to the hinge 3, and when the door body 2 needs to continue to open, it saves the user's effort.

[0030] On the horizontal side of the limiting member 5, there is a side plate 53 for locking it to the side of the box body 1. A locking hole is provided on the side plate 53. This structure facilitates locking the limiting member 5 to the side of the box body 1, and it can be locked by screws, making the installation convenient.

[0031] The front end of the hinge 3 is connected to the edge of the side of the door body 2. The middle part of the hinge 3 is rotatably connected to the outer side wall of the box body 1. A hook 31 is provided at the rear end of the hinge 3, and the end of the first section 411 of the pull rope 41 is hung on the hook 31.

[0032] The hook 31 has a U-shaped structure, and the height of the rear side of the U-shaped structure is less than that of the front side. When the limiting member 5 and the hinge 3 are in a mutually limiting state, the upper end of the rear side of the hook 31 abuts against the bottom of the limiting member 5. This structure provides better resistance when the hinge 3 is in a certain state, and when the door body 2 needs to be opened further, it makes it easier for the user to operate.

[0033] A base 6 is provided at the bottom of the box body 1. The adjusting assembly 4 is arranged on the outer side wall of the base 6 and is located below the hinge 3.

[0034] The elastic member 42 is arranged horizontally and its front end is connected to the front edge of the base 6. The first end of the second section 412 of the pull rope 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 above the elastic member 42. The second section 412 of the pull rope 41 bypasses the first pulley 43 and the second pulley 44 from bottom to top to form two relatively parallel parts, and the first section 411 of the pull rope 41 extends obliquely from the bottom of the second pulley 44 towards the hinge 3. The above structure facilitates using the elastic member 42 to achieve the hovering of the door body 2.

[0035] A door lock structure 7 capable of locking or unlocking is provided between the front edge of the top of the box body 1 and the top edge of the door body 2. Setting the door lock here makes it convenient for the door body 2 to open under its own gravity when in the unlocked state.

[0036] In this embodiment, when the door needs to be opened after washing is completed, the user does not need to pull the door body 2 forcefully. The door body 2 can automatically open to an angle A under the action of its own gravity to allow the hot steam in the washing cavity to be discharged. Then the user can continue to open the door body 2 at a larger angle by pulling the door handle. And since the tension of the pull rope 41 starts to act 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 beneficial to improving the user experience.
