Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dishwashers, specifically to a door sealing structure and a household appliance. Background Technology
[0002] Household appliances with washing functions, such as dishwashers or other cleaning machines for washing towels.
[0003] To prevent liquid from leaking out of the inner tank during dishwasher or washing machine operation, a sealing ring is installed on the door to seal the gap between the inner tank opening and the door. If a pull-out door is used, when the door is opened, if the inside of the door is damp, the liquid will drip down the bottom of the door, requiring the user to clean it, resulting in a poor user experience. Utility Model Content
[0004] This utility model proposes a door sealing structure. The sealing element is set at the bottom of the door. When the door is opened, if there is moisture in the bottom of the door, the liquid in the bottom of the door will drip onto the inner tank water guide under the action of gravity during the opening process. Since the inner tank water guide extends upward and outward from the opening of the inner tank, it prevents the liquid from leaking outward from the opening of the inner tank, thus avoiding water leakage during the opening process and improving the user experience.
[0005] A door sealing structure designed for this purpose includes an inner liner water guide that seals with the door. The inner liner water guide extends upward toward the opening of the inner liner and is disposed on the inner liner. A sealing element is provided on the door. When the door is closed, the sealing element abuts against the inner liner water guide. When the door is open, the sealing element disengages from the inner liner water guide, and the inner liner water guide forms a water guiding structure for guiding liquid to flow along the inner side of the inner liner.
[0006] The inner liner water guide is provided with a guide surface for guiding the flow of liquid. The guide surface is a guide arc surface or a guide slope surface.
[0007] The inner liner water guide component is integrally formed with the inner liner and is configured as an inseparable whole; or, the inner liner water guide component is separately configured with the inner liner, and the inner liner water guide component is detachably connected to the inner liner.
[0008] The inner tank water guide extends upward from the bottom wall of the inner tank and is installed on the inner tank. The door body is provided with a clearance groove corresponding to the upwardly extended inner tank water guide. When the door body is closed, one end of the inner tank water guide extends into the clearance groove.
[0009] The sealing element is provided with a first sealing rib. When the door is closed, the first sealing rib abuts against the inner tank water guide, and the first sealing rib and the inner tank water guide form a first sealing fit.
[0010] The sealing element is provided with a second sealing rib. When the door is closed, the second sealing rib abuts against the inner tank water guide. The second sealing rib and the inner tank water guide form a second sealing fit. When the door is closed, the first sealing rib and the second sealing rib form a double sealing structure between the sealing element and the inner tank water guide.
[0011] The door body is provided with a sealing groove for installing a sealing element. An anti-disengagement engagement part is provided between the sealing element and the sealing groove. The sealing element is positioned and installed on the sealing groove of the door body through the anti-disengagement engagement part.
[0012] The door is a folding door, which includes a first door and a second door. A hinge is provided between the first door and the second door, and the first door and the second door can be switched to an open or closed folding state through the hinge.
[0013] The folding opening and closing joint between the first door and the second door is provided with an anti-seepage component to prevent liquid from seeping out of the door. The anti-seepage component includes an anti-seepage element with a water receiving groove. The anti-seepage element is set vertically or at an angle when the folding door is in the closed folding state to block liquid from seeping out of the door along the hinge opening and closing joint between the first door and the second door.
[0014] A household appliance includes a body, the body having the aforementioned door sealing structure, an inner liner disposed inside the body, and a door opening and closing mechanism disposed on the outside of the body.
[0015] The beneficial technical effects of this utility model are as follows:
[0016] The sealing element is located at the bottom of the door. When the door is opened, if there is moisture at the bottom of the door, the liquid at the bottom of the door will drip onto the inner tank water guide under the action of gravity during the opening process. Since the inner tank water guide extends upward and outward from the opening of the inner tank, it prevents the liquid from leaking outward from the opening of the inner tank, thus avoiding water leakage during the opening process and improving the user experience.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.
[0029] See Figures 1-10 A door sealing structure includes an inner liner water guide 3 that seals with the door 2. The inner liner water guide 3 extends upward toward the opening of the inner liner 1 and is disposed on the inner liner 1. A sealing element 4 is provided on the door 2. When the door 2 is in the closed state, the sealing element 4 abuts against the inner liner water guide 3. When the door 2 is in the open state, the sealing element 4 disengages from the inner liner water guide 3. The inner liner water guide 3 forms a water guide structure for guiding liquid to flow along the inner side of the inner liner 1.
[0030] The sealing element 4 is located at the lower part of the door body 2. When the door body 2 is opened, if there is moisture at the lower part of the door body 2, the liquid at the lower part of the door body 2 will drip onto the inner tank water guide 3 under the action of gravity during the opening process. Since the inner tank water guide 3 extends upward towards the outside of the opening of the inner tank 1, it prevents the liquid from leaking outward from the opening of the inner tank 1, thus avoiding water leakage during the opening of the door body 2 and improving the user experience.
[0031] When the door 2 is closed on the dishwasher, the seal 4 follows the door 2 and folds inward to abut against the water receiving channel (which can be understood as the inner side of the inner tank water guide 3 and the inner tank 1 forming a water receiving channel), thereby achieving a seal; when the door 2 is folded outward, the lower part of the door 2 and the seal 4 fold outward and open towards the dishwasher. When water drips from the door 2, the water will drip onto the inner tank water guide 3, and the liquid in the inner tank water guide 3 will flow into the inner tank 1 along the guide surface 5. During the opening of the door 2, if the lower part of the door 2 is covered with water vapor, the liquid in the lower part of the door 2 will not easily drip out of the dishwasher.
[0032] The inner liner water guide 3 is provided with a guide surface 5 for guiding the flow of liquid. The guide surface 5 is a guide arc surface or a guide slope surface.
[0033] The guide surface 5 is a guide slope or a guide arc surface. The height of the outer end of the guide surface 5 near the opening of the inner liner 1 is higher than the height of the inner end of the guide surface 5 near the inner liner 1. The guide surface 5 extends upward along the outer side of the opening of the inner liner 1, so that the liquid located at the high point of the guide surface 5 flows towards the low point of the guide surface 5, so that the liquid located on the inner liner water guide 3 flows back into the inner liner 1 along the inclined or arc-shaped guide surface 5.
[0034] The inner liner water guide component 3 is integrally formed with the inner liner 1 and is configured as an inseparable whole; or, the inner liner water guide component 3 and the inner liner 1 are separately configured, and the inner liner water guide component 3 and the inner liner 1 are detachably connected.
[0035] The inner tank water guide 3 extends upward from the bottom wall of the inner tank 1 and is provided on the inner tank 1. The door body 2 is provided with a clearance groove 7 corresponding to the upwardly extended inner tank water guide 3. When the door body 2 is in the closed state, one end of the inner tank water guide 3 extends into the clearance groove 7.
[0036] Because an inner liner water guide 3 is added between the door body 2 and the inner liner, to prevent the door body 2 from being located outside the inner liner water guide 3 when closed, a clearance groove 7 is provided at the bottom of the door body 2. In both the open and closed states of the door body 2, the inner liner water guide 3 is always limited within the clearance groove 7. With this structure of adding the inner liner water guide 3, not only is the sealing structure of the inner liner 1 of the door body 2 not affected, but water leakage is also prevented during the opening of the door body 2.
[0037] The sealing element 4 is provided with a first sealing rib 8. When the door body 2 is closed, the first sealing rib 8 abuts against the inner tank water guide 3, and the first sealing rib 8 and the inner tank water guide 3 form a first sealing fit.
[0038] The sealing element 4 is provided with a second sealing rib 9. When the door body 2 is closed, the second sealing rib 9 abuts against the inner tank water guide 3. The second sealing rib 9 and the inner tank water guide 3 form a second sealing fit. When the door body 2 is closed, the first sealing rib 8 and the second sealing rib 9 form a double sealing structure between the sealing element 4 and the inner tank water guide 3.
[0039] In this embodiment, the first sealing rib 8 and the second sealing rib 9 form a 7-shaped structure on the sealing element 4. The 7-shaped structure of the sealing element has more than two sealing points, which can improve the sealing effect. When the first sealing rib 8 fails, the second seal 9 can also prevent the liquid in the inner liner 1 from entering the interior of the door body 2 along the vent groove 7.
[0040] The door body 2 is provided with a sealing groove 10 for installing a sealing element 4. An anti-disengagement engagement part 12 is provided between the sealing element 4 and the sealing groove 10. The sealing element 4 is positioned and installed on the sealing groove 10 of the door body 2 through the anti-disengagement engagement part 12.
[0041] The anti-disengagement engagement part 12 includes a rib 12 disposed on the inner side of the sealing groove 10 and a fin 11 disposed on the sealing member 4. The sealing member 4 is inserted into the sealing groove 10, and the fin 11 abuts against the rib 12 to prevent the sealing member 4 from disengaging from the sealing groove 10.
[0042] The door 2 is a folding door, which includes a first door 15 and a second door 16. A hinge is provided between the first door 15 and the second door 16, and the first door 15 and the second door 16 can be switched to an open or closed folding state through the hinge.
[0043] Folding the two doors together reduces the space occupied when the doors are open.
[0044] An anti-seepage component 17 is provided at the folding opening and closing joint between the first door body 15 and the second door body 16 to prevent liquid from seeping out of the door body. The anti-seepage component 17 includes an anti-seepage element 19 with a water receiving groove 18. The anti-seepage element 19 is vertically or inclined when the folding door body is in the closed folding state to block liquid from seeping out of the door body 2 along the hinge opening and closing joint between the first door body 15 and the second door body 16.
[0045] When the first door 15 and the second door 16 are in the process of being opened, if there is liquid on the first door 15, the water receiving groove 18 of the waterproof component 19 can catch the liquid dripping from the first door 15.
[0046] A household appliance includes a body 20, on which the aforementioned door sealing structure is provided, an inner liner 1 is disposed inside the body 20, and a door 2 is disposed on the outside of the body 20 for opening and closing.
[0047] In this embodiment, the household appliance is a dishwasher.
[0048] 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.
