The present disclosure relates to the field of kitchen appliance technologies, and in particular, to a dishwasher.
Dishwashers are kitchen appliances for automatically cleaning tableware with ever-growing need for more and more ordinary families. Generally, a door body and an inner container of a dishwasher are sealed and engaged by a sealing structure. For a traditional dishwasher, the sealing structure around an opening of the inner container is formed by bending an edge of the opening of the inner container, which complicates the inner container in shape, results in high processing difficulty, and lowers production efficiency.
An object of the present disclosure is to provide a dishwasher, which aims to solve at least a technical problem of simplifying an inner container structure of a dishwasher.
In order to realize the above purpose, the dishwasher according to the present disclosure includes: an inner container having an accommodation cavity, the accommodation cavity having an opening facing forward; a frame connected to an outer surface of the inner container and extending along an edge of the opening of the accommodation cavity, a sealing groove being defined in the frame, or the sealing groove being defined by enclosing the frame and the edge of the opening of the inner container, and a sealing strip being disposed in the sealing groove; and a door body configured to open or close the opening of the accommodation cavity, the door body abutting against the sealing strip in response to the opening of the accommodation cavity being covered by the door body.
In one embodiment, the sealing groove is directly defined in the frame and extends in a length direction of the frame.
In one embodiment, a front end of the sealing strip protrudes from the opening of the sealing groove to ensure that the door body is in effective contact with the sealing strip.
In one embodiment, the sealing strip is embedded in the sealing groove.
In one embodiment, the sealing strip is made of a foaming material.
In one embodiment, the frame includes: a supporting frame strip abutting against the outer surface of the inner container; and an engagement frame strip connected to a front side wall of the supporting frame strip and spaced apart from the outer surface of the inner container.
The edge of the opening of the inner container protrudes from the front side wall of the supporting frame strip. The sealing groove is located between the fitting frame strip and the edge of the opening of the inner container.
In one embodiment, the door body includes an outer door, and an inner door arranged on an inner surface of the outer door. When the opening of the accommodation cavity is closed by the door body, the inner door abuts against the sealing strip.
In one embodiment, a periphery of the inner door abuts against the sealing strip; and a front side wall of the fitting frame strip protrudes from the edge of the opening of the inner container.
In one embodiment, when the inner door abuts against the sealing strip, a part of the fitting frame strip protruding from the opening of the tub is arranged around a peripheral side of the inner door.
In one embodiment, an abutting rib is disposed on and protrudes from an end, facing away from the sealing groove, of a front side wall of the fitting frame strip, a front end of the abutting rib being bent outwards to form a positioning edge. The dishwasher further includes a casing with an opening facing forward. The inner container is arranged in the casing. An edge of the opening of the casing abuts against the positioning edge.
In one embodiment, the frame is detachably connected to the inner container.
In one embodiment, a side wall of the inner container has a through hole. The supporting frame strip has a fixing hole corresponding to the through hole. The through hole and the fixing hole are connected to each other by a fastener.
In one embodiment, the edge of the opening of the inner container is bent backwards to form a reinforcement flange.
In one embodiment, the frame has a lock configured to lock or unlock the door body.
In one embodiment, the frame is configured as a plastic frame.
According to the dishwasher of the present disclosure, the frame is arranged at the edge of the opening of the inner container to enable the frame to form the sealing groove by the frame or form the sealing groove by enclosing the frame and the side wall of the inner container. Further, the sealing strip is disposed in the sealing groove. Therefore, when the opening of the accommodation cavity is closed by the door body, the door body may abut against the sealing strip to realize a sealing engagement between the door body and the inner container. The sealing groove is formed by the frame or is formed by enclosing the frame and the inner container.
Therefore, a structure of the inner container may be effectively simplified to reduce production difficulty and improve processing efficiency.

The present disclosure provides a dishwasher.
According to these embodiments of the present disclosure, as illustrated in
In the embodiment, a bowl basket may be disposed in the accommodation cavity and is configured to carry tableware. In addition, a spray arm may also be disposed in the accommodation cavity to spray a fluid towards the bowl basket for cleaning the tableware. The spray arm may be disposed at both an upper part and a lower part of the bowl basket to spray the fluid in several directions. The opening of the accommodation cavity faces forward. The door body 30 is disposed on a front side of the inner container 10. It should be noted that the terms “front” and “rear” refers to a relative direction, and a side where the opening of the inner container 10 is located is defined as the front side. The door body 30 and the inner container 10 may be rotatably connected to each other. For example, a bottom of the door body 30 is rotatably connected to the inner container 10. In addition, in other embodiments, other connection manners may also be adopted between the door body 30 and the inner container 10, which is not limited in these embodiments of the present disclosure.
The frame 20 may be connected to an inner surface or the outer surface of the inner container 10, which is not limited herein. The frame 20 is located adjacent to the edge of the opening and extends in a length direction adjacent to the edge of the opening. For example, the opening is defined by three side walls. The door body 30 is rotatably connected to an edge of a bottom side wall. The frame 20 extends along edges of the three side walls. A specific structure of the frame 20 is not limited herein, as long as the sealing groove 21 may be formed by the frame 20. The sealing groove 21 may be formed by the frame 20 itself, or may be formed by enclosing the frame 20 and side walls of the inner container 10, which is not limited herein, as long as the sealing groove 21 is opened forwards. For example, the sealing groove 21 is directly defined in the frame 20 and extends in a length direction of the frame 20.
The sealing strip is embedded in the sealing groove 21. The sealing strip may be made of a foaming material to improve fitting sealing performance with the sealing groove 21 and abutting sealing performance of against the door body 30. A front end of the sealing strip may protrude from the opening of the sealing groove 21 to ensure that the door body 30 is in effective contact with the sealing strip. After the door body 30 abuts against the sealing strip, a sealing fitting between the door body 30 and the inner container 10 may be achieved to avoid fluid or air leakage during an operation of the dishwasher. The frame 20 is configured as a plastic frame to be formed by injection molding, to improve production efficiency and reduce production costs. Since production and processing of the frame 20 is simpler and more convenient than directly bending the edge of the opening of the inner container 10 to form the groove structure, a structure of the inner container 10 may be simplified through forming the sealing groove 21 by the frame 20 to improve production and processing efficiency of the dishwasher.
According to the dishwasher of the present disclosure, the frame 20 is arranged at the edge of the opening of the inner container 10 to form the sealing groove 21 by the frame 20 or form the sealing groove 21 by enclosing the frame 20 and the side walls of the inner container 10. Further, the sealing strip is disposed in the sealing groove 21. Therefore, when the opening of the accommodation cavity is closed by the door body 30, the door body 30 may abut against the sealing strip to realize the sealing fitting between the door body 30 and the inner container 10. The sealing groove 21 is formed by the frame 20 or is formed by enclosing the frame 20 and the inner container 10. Therefore, the structure of the inner container 10 can be effectively simplified to reduce production difficulty and improve processing efficiency.
