Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically to a folding door and a household appliance. Background Technology

[0002] Most current household appliances have drawer-style doors. For example, dishwashers or sterilizers use drawer-style racks that are pulled out or pulled into the appliance's interior. Alternatively, some appliances use a flip-open design, where the lower part of the door is hinged to the appliance body, and the upper part is snapped shut. The interior is opened and closed by flipping the door up and down. Some appliances, like refrigerators, have left-right opening mechanisms. All these doors open to the outside of the appliance, occupying space on the outer side and resulting in excessive space usage when fully open.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] This utility model proposes a folding door and a household appliance, which divides the entire door into two parts: a first door and a second door. A hinge is provided between the first and second door. When closed, the first and second door are in the open state and form an upright door. During the opening process, pulling the first door causes it to rotate relative to the second door. When the two doors have rotated and opened to a certain position angle, the first door folds upward onto the second door, effectively reducing the problem of occupying too much space when the door is folded down.

[0005] A folding door designed for this purpose includes a first door and a second door, with a hinge connecting the first door and the second door; when in the open state, the first door and the second door are folded together.

[0006] Decorative elements are provided at the corresponding hinges between the first door body and the second door body, forming a decorative structure for concealing the hinges.

[0007] During the opening process of the first door and the second door, the opening angle A between the first door and the second door gradually decreases.

[0008] When the first door and the second door are opened, they are in a folded state, and the folding angle between the first door and the second door is an acute angle, an obtuse angle, or a right angle.

[0009] The opening and closing fold between the first door and the second door is provided with a guide slope for guiding the flow of liquid.

[0010] The opening and closing fold between the first door and the second door is equipped with a waterproof component to prevent liquid from seeping out of the door.

[0011] The waterproof component includes a water-blocking member installed at the opening and closing fold between the first door and the second door. The water-blocking member is installed vertically or at an angle when the folded door is closed, and one end of the water-blocking member is sealed and fixedly connected to the corresponding door to prevent liquid from seeping out of the folded door through the opening and closing fold between the two doors.

[0012] The waterproof component includes a water-blocking fitting disposed at the opening and closing folding joint between the first door and the second door. When the first door and the second door are in the closed state, the water-blocking component and the water-blocking fitting cooperate with each other. When the first door and the second door are in the open state, the water-blocking component and the water-blocking fitting are separated. The water-blocking fitting is provided with a water-receiving groove, which is used to collect liquid on the folding door to prevent liquid from seeping out of the folding door during the opening process.

[0013] The folding door is equipped with a sealing strip for waterproofing.

[0014] A household appliance includes a body with the aforementioned folding door. The lower part of the second door is hinged to the body, and the upper part of the first door is fastened to the inner side of the body. When the first door is flipped open to the outside of the body, the second door gradually opens on the body via a hinge. When the two doors are opened to corresponding positions and angles, the two doors are in a folded state.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] The entire door is divided into two parts: a first door and a second door, connected by a hinge. The first door is located at the top, and the second door at the bottom; the first door is the upper door, and the second door is the lower door. When closed, the first and second doors are in the open state, forming an upright door. During opening, pulling the first door causes it to rotate relative to the second door. When the two doors have rotated to a certain angle, the first door folds upwards onto the second door, effectively reducing the space occupied when the door is folded down.

The second mounting position 12 is provided with a second fastening hole 15 for inserting a second fastener. The other end of the hinge 3 is fixed on the second door body 2 by the second fastener.

[0052] In this embodiment, the fastener is a screw.

[0053] In this embodiment, the hinge 3 includes a first hinge joint 19 and a second hinge joint 20. Both the first hinge joint 19 and the second hinge joint 20 are provided with fixing blocks 21 fixed on the corresponding door mounting positions. Each fixing block 21 is provided with through holes for fasteners such as screws. A multi-link assembly 22 is provided between the first hinge joint 19 and the second hinge joint 20. One end of the multi-link assembly 22 is connected to the first hinge joint 19, and the other end of the multi-link assembly 22 is connected to the second hinge joint 20.

[0054] The multi-link assembly 22 includes a first link group and a second link group, with their ends hinged together. The first link group is connected to a first hinge joint 19, and the second link group is hinged to a second hinge joint 20.

[0055] The decorative element 4 has a second recess 17. During the opening and closing of the first door 1 and the second door 2, the hinge 3 is always hidden in the second recess 17 of the decorative element 4.

[0056] During the opening process of the first door 1 and the second door 2, the opening angle A between the first door 1 and the second door 2 gradually decreases.

[0057] When the first door 1 and the second door 2 are opened, they are in a folded state, and the folding angle between the first door 1 and the second door 2 is an acute angle, an obtuse angle, or a right angle.

[0058] The opening and closing fold between the first door body 1 and the second door body 2 is provided with a guide slope 25 for guiding the flow of liquid. When the folding door body is in the closed use state, if liquid enters the opening and closing fold between the two door bodies, the liquid can flow along the guide slope 25 towards the inside of the door body.

[0059] A waterproof component 23 is provided at the opening and closing fold between the first door body 1 and the second door body 2 to prevent liquid from seeping out of the door body.

[0060] The waterproof component 23 includes a water-blocking member 24 disposed at the opening and folding joint between the first door body 1 and the second door body 2. The water-blocking member 24 is vertically or obliquely arranged in the closed state of the folding door body, and one end of the water-blocking member 24 is fixedly connected to the corresponding door body in a sealed manner to prevent liquid from leaking out of the folding door body along the opening and folding joint between the two door bodies.

[0061] The waterproof component 23 includes a water-blocking cooperation member 26 disposed at the opening and folding joint between the first door body 1 and the second door body 2. When the first door body 1 and the second door body 2 are in the closed state, the water-blocking member 24 cooperates with the water-blocking cooperation member 26. When the first door body 1 and the second door body 2 are in the open state, the water-blocking member 24 is separated from the water-blocking cooperation member 26. A water-receiving groove 27 is provided on the water-blocking cooperation member 26, and the water-receiving groove 27 is used to receive the liquid on the folding door body to prevent the liquid from leaking out of the folding door body during the opening process of the folding door body.

[0062] In this embodiment, the water-blocking cooperation member 26 is provided with a groove in a shape like a capital "J", and the water-blocking member 24 is in a similar "L" shape. When the first door body 1 and the second door body 2 are in the closed state, the water-blocking member 24 is positioned on the groove of the water-blocking cooperation member 26. If liquid enters the opening and folding joint between the two door bodies, the "L"-shaped water-blocking member 24 effectively blocks the liquid from continuing to leak outwards along the opening and folding joint between the two door bodies, and the liquid can only flow back to the inner side of the door body along the diversion inclined plane 25.

[0063] When the two door bodies are opened, if there is liquid on the inner side of the door body, the water-receiving groove 27 can receive the liquid to prevent the liquid from dripping outside the door body. When the door body is closed again, the liquid in the water-receiving groove 27 flows along the diversion inclined plane 25 towards the inner side direction of the door body.

[0064] A sealing strip 28 for sealing and waterproofing is provided on the folding door body.

[0065] A household appliance includes a machine body 第十八条18, and the above-mentioned folding door body is provided on the machine body 第十八条18. The lower part of the second door body 2 is hinged to the machine body 第十八条18, and the upper part of the first door body 1 is snap-connected to the inner side of the machine body 第十八条18. When the first door body 1 is flipped open towards the outside of the machine body 第十八条18, the second door body 2 is gradually opened on the machine body 第十八条18 through the hinge 3 following the first door body 1. When the two door bodies are opened to the corresponding position angles, the two door bodies are in a folded state.

[0066] In this embodiment, the hinging of the second door body 2 as the lower part of the door body to the machine body 第十八条18 is a prior art and will not be elaborated here.

[0067] Furthermore, in this embodiment, the folding angle between the first door 1 and the second door 2 after opening varies depending on the hinge. Therefore, this embodiment only describes that after the doors are opened, the first door 1 can fold upwards onto the second door 2, and the folding angle can be 90° or less. When the first door 1 is folded upwards, it tilts slightly downwards towards the second door 2, and the angle between the lines intersecting the first door 1 and the second door 2 is less than 90°. Under the action of gravity, the first door 1 remains slightly tilted downwards towards the second door 2, so that after the two doors are opened, they remain in a folded state.

[0068] In this embodiment, the hinge 3 can be a damped hinge in the prior art, which can achieve free hovering. The damped hinge has various structures, and its specific structure will not be described in detail here.

[0069] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
