In an embodiment of the present invention, as shown in fig. 1 to 6, the dishwasher includes:

a base 100, wherein a washing chamber chassis 410 is arranged on the top of the base 100, and a door matching position 110 is arranged at the front end of the washing chamber chassis 410;

the door body 200 is rotatably arranged on the base 100, and a sealing strip 210 is arranged on one side, close to the door matching position 110, of the door body 200;

the two ends of the door matching position 110 are provided with the blocking protrusions 300, the door body 200 is closed, and the sealing strip 210 can be abutted against the door matching position 110 and the blocking protrusions 300 at the same time.

It will be appreciated that the dishwasher has a washing chamber 400, the washing chamber 400 being used to load dishes, the washing chamber 400 having a washing chamber chassis 410, and left, right, rear and top side walls assembled with the washing chamber chassis 410, the entire washing chamber 400 being mounted above the base 100, and that, in operation of the dishwasher, water is sprayed by the spray arms and falls onto the washing chamber chassis. The opening of the washing chamber 400 is referred to as the front of the dishwasher according to the habit of the user using the dishwasher, and the relative positions of other orientations are schematically shown in the drawings. In this embodiment, the door 200 is rotatably connected to the base 100 to open and close the opening of the washing chamber 400, and the washing chamber chassis 410 is a portion, called the door engaging portion 110, that cooperates with the door 200 to seal the opening. Thus, the door 200 is rotated downward to expose the opening of the washing chamber 400, so that the user can put the dishes to be washed into the washing chamber 400 through the opening; the door 200 is rotated upward to cover the opening of the washing chamber 400, and the dishwasher can perform washing according to a control command of a user.

The two sides of the washing chamber chassis 410 are further provided with guide rails 120 for the rollers of the dish basket to roll, when the door 200 is opened, the dish basket can be pulled to enter and exit the washing chamber 400 under the guiding action of the guide rails 120, so that the user can conveniently put dishes to be washed or take out clean dishes after washing. Particularly, in order to avoid the door body 200, the front end of the guide rail 120 is provided with a yielding notch 130 so as to avoid interference with the door body 200 in the process of closing the door body 200. However, when the dish washer washes dishes, sewage easily flows from the side to the front end of the washing chamber 400 through the gap formed by the abdicating notch 130 and the washing chamber chassis 410 by the door body 200, that is, flows to the door matching position 110, that is, the front end of the base 100, so that the door matching position 110 at the front end of the base 100 retains dirt, and when the door is pulled after the washing is finished, a part of sewage flows out from the door matching position 110, which affects the use experience of the user; further, due to the existence of the door body 200, stains at the position are inconvenient to clean, and the stains are accumulated at the position even generate peculiar smell in the past, so that the user experience is seriously influenced.

In this embodiment, the two ends of the door fitting portion 110 are provided with the blocking protrusions 300, so that the blocking protrusions 300 are fitted with the sealing strips 210, and can block the sewage flowing to the door fitting portion 110 from both sides. Specifically, the door body 200 is close to one side of door cooperation position 110 is equipped with sealing strip 210, sealing strip 210 is in the door body 200 can butt simultaneously when closing in door cooperation position 110 with keep off protruding 300, so, on the one hand, sealing strip 210 is sealed the door body 200 with the seam of door cooperation position 110 can avoid when washing tableware the outside water of door body 200 downside, on the other hand, sealing strip 210 can with keep off protruding 300 and closely cooperate to play sealed effect, avoid producing the fit clearance and make sewage pass through. Therefore, according to the technical scheme of the invention, the sewage can be effectively prevented from flowing to the door matching position 110, namely, no stain is accumulated at the front end of the base 100, and the use experience of a user can be greatly improved.

Further, referring to fig. 2, the direction of the door 200 is taken as the front, when the door 200 is closed, the blocking protrusion 300 is located in front of the sealing strip 210, that is, after the door 200 is closed, the door 200 can block the blocking protrusion 300, so that the blocking protrusion 300 does not occupy the inner space of the washing chamber 400. In addition, it can be understood that the door body 200 is hinged to the base 100 through two sides of the bottom of the door body 200, so that the door body 200 moves to rotate around an axis, and the blocking protrusion 300 is located in front, that is, in the moving direction of the door body 200, so that the door body 200 drives the sealing strip 210 to abut against the blocking protrusion 300 better, and the sealing effect can be further improved.

Further, referring to fig. 2 again, the portion of the sealing strip 210 abutting against the stop protrusion 300 is located in front of and/or above the portion of the sealing strip 210 abutting against the door fitting portion 110. In this manner, the sealing strip 210 can achieve an effective seal in two different directions. It can be understood that after the door 200 closes the opening of the washing chamber 400, there are two main water leakage directions at the bottom of the opening of the washing chamber 400, the first is water leakage along the length direction of the sealing strip 210 (left and right directions in the drawing), and the other is water leakage along the gap formed by the abdicating notch 130 and the washing chamber chassis 410 of the door 200, that is, there are two water leakage directions, in this embodiment, the position where the sealing strip 210 is abutted is set to two different directions, so as to adapt to different water leakage directions, and thus the sealing strip 210 can be prevented from deforming to form a new water leakage point, for example, as described below, the sealing strip 210 is abutted with the baffle 300 through the sealing strip body 211, and is abutted with the door matching position through the sealing strip skirt 212.

Further, in this embodiment, as shown in fig. 1, fig. 2, fig. 7 and fig. 8, a groove 220 is disposed on a side of the door body 200 close to the door fitting position 110, the sealing strip 210 is disposed in the groove 220, when the door body 200 is closed, the blocking protrusion 300 is accommodated in the groove 220, and two ends of the sealing strip 210 abut against a rear side of the blocking protrusion 300. In order to avoid that the door body 200 rotates, the structure of the door body 200 itself and the door cooperation position 110 interfere with each other, the door body 200 is close to one side of the door cooperation position 110 is provided with a groove 220, and the sealing strip 210 is arranged in the groove 220, so that the sealing strip 210 can avoid the interference between the door body 200 and the cooperation of the base 100.

Particularly, both ends of the sealing strip 210 are abutted against the rear side of the blocking protrusion 300, so that the sealing strip 210 and the blocking protrusion 300 can be more tightly matched, the upper end of the sealing strip 210 is connected with the inner door, and the lower end of the sealing strip 210 is abutted against the rear end of the blocking protrusion 300, so that the sealing strip 210 can reliably seal both sides of the base 100, and the phenomenon that the dirt is accumulated in the door matching position 110 at the front end of the base 100 due to the flowing of the sewage from both sides is avoided. Of course, in another embodiment, both ends of the weather strip 210 may be abutted against the front side of the blocking protrusion 300 to reduce the requirement of the fitting accuracy between the blocking protrusion 300 and the door body 200, thereby reducing the machining accuracy of the blocking protrusion 300.

Further, in the present embodiment, the blocking protrusion 300 is a separate member, and is installed to the door fitting site 110 after being formed, so that the blocking protrusion 300 can be separately manufactured. It can be understood that the structure of the blocking protrusion 300 is small, and in order to avoid interference on the assembly of the door body 200, the requirement on the machining precision is inconsistent with other structures of the base 100, and the blocking protrusion is manufactured separately as a separate component, so that the precision requirement on the mold of the base 100 can be reduced, and the production and manufacturing cost of the dishwasher can be reduced.

Further, in this embodiment, the blocking protrusion 300 is detachably mounted on the door fitting portion 110. It can be understood that the structure of the blocking protrusion 300 may be deformed or damaged during the process of fitting with the door body 200, which may cause the sealing strip 210 to be not tightly fitted with the blocking protrusion 300 or the sewage to seep to the front end of the base 100 through the crack of the blocking protrusion 300. The blocking protrusion 300 is detachably mounted on the door fitting portion 110, and can be conveniently replaced when damaged or deformed, so that the structure of the blocking protrusion 300 can play a role in water blocking.

Further, in the present embodiment, the blocking protrusion 300 is mounted on the door fitting site 110 by a snap-fit or plug-in manner or a screw locking manner. It can be understood that, in the process of opening the door body 200 or closing the door body 200, the blocking protrusion 300 and the sealing strip 210 have an interaction force, the blocking protrusion 300 is installed on the door fitting position 110 in a clamping or inserting manner or a screw locking manner, so that the blocking protrusion 300 is stably connected to the door fitting position 110, and the blocking protrusion 300 is prevented from falling off from the door fitting position 110.

Further, in this embodiment, the blocking protrusion 300 is made of a plastic material or a metal plate material; furthermore, the base 100 is made of plastic or metal plate, so that the plastic has good wear resistance and low cost, the metal plate has high strength and high cost, and different materials can be selected according to different requirements in practical application. Without loss of generality, in order to obtain the highest cost performance, the material of the blocking protrusion 300 and the material of the base 100 can both be plastic materials; for satisfying the requirement of high quality, keep off protruding 300 the material with the panel beating material can all be chooseed for use to the material of base 100.

Of course, in other embodiments, the blocking protrusion 300 and the base 100 may be integrally disposed, so as to improve the structural stability of the connection between the blocking protrusion 300 and the base 100. Optionally, when the material of the blocking protrusion 300 is a plastic material, the blocking protrusion 300 is integrally formed with the base 100 by injection molding; optionally, work as keep off protruding 300 with when the material of base 100 is the panel beating material, keep off protruding 300 with the mode integrated into one piece of base 100 accessible punching press, above-mentioned mode all is favorable to the mass production of product.

Further, in the present embodiment, the height of the blocking protrusion 300 is not less than 17 mm. Here, the height refers to a shortest straight distance from an upper end to a lower end of the blocking protrusion. It can be understood that the dishwasher has various operation modes, and the water level in the washing chamber 400 is also different in the various operation modes, and when the height of the blocking protrusion 300 is set to be not less than 17mm, the dishwasher can block the sewage in various washing modes.

Further, in the present embodiment, the length of the blocking protrusion 300 ranges from 8mm to 12 mm. It should be noted that, the length is the shortest straight-line distance from the left end to the right end of the blocking protrusion 300, and it can be understood that if the length of the blocking protrusion 300 is too short, the effect of blocking sewage will be very low; if the length of the blocking protrusion 300 is too long, it may cause too much resistance to the opening and closing of the door 200. The length range of the blocking protrusion 300 is controlled to be 8mm to 12mm, so that the blocking protrusion can block sewage and cannot cause excessive resistance to opening and closing of the door body 200.

Further, in this embodiment, as shown in fig. 7 and 8, the sealing strip 210 includes a sealing strip body 211 and a sealing skirt 212, the sealing strip body 211 is connected to the door body 200, when the door body 200 is closed, the sealing skirt 212 abuts against the door fitting portion 110, and two ends of the sealing strip body 211 abut against the blocking protrusions 300. Thus, the sealing strip 210 can be respectively matched with the door body 200, the blocking protrusion 300 and the door matching position 110 through different structures on the sealing strip. Specifically, the sealing strip 210 and the door body 200 can be fixedly connected by connecting the sealing strip body 211 to the door body 200, and sealing can be formed at the position of the blocking protrusion 300 by abutting two ends of the sealing strip body 211 against the blocking protrusion 300; a seal is formed at the door mating location 110 by abutting the sealing skirt 212 against the door mating location 110. The weather strip body 211 and the weather skirt are in work cooperation, and the functions of the other weather strip body and the weather skirt are not required to be considered, so that the weather strip body and the weather skirt can have good effects. Of course, in other embodiments, the weather strip 210 may have other shapes, and only needs to have a structure that can be used for connection with the door body 200, abutment against the door engagement portion 110, and abutment against the stopper projection 300.

Further, the sealing strip body 211 and the blocking protrusion 300 abut to form an interface extending vertically. As described above, the stopping protrusion 300 is located in the front, i.e. in the moving direction of the door body 200, and the interface extends vertically, i.e. the interface is perpendicular to the tangential direction of the moving direction of the door body 200, so that the force generating effect is the best, and the contact effect is the best.

The interface formed by the sealing strip body 211 and the baffle projection 300 in a butting way is a plane. For example, the sealing strip body 211 has a flat surface, and the retaining protrusion 300 has a flat surface, which are abutted. For another example, the weather strip body 311 has a curved surface and deforms into a flat surface when in contact therewith. By designing the interface as a flat surface, the risk of interface water leakage is reduced.

Further, in the present embodiment, as shown in fig. 7 and 8, the end of the sealing skirt 212 extends away from the door fitting portion 110, i.e., rearward in the direction shown in the drawing. In the prior art, the end of the sealing skirt 212 extends toward the front end of the door fitting portion 110, and once the front end of the seat base 100 is filled with sewage, the sealing skirt 212 blocks the outflow of the sewage. The prior art seal 210 is constructed to easily retain dirt and soil and is inconvenient to clean the sealing skirt 212. In this embodiment, the end of the sealing skirt 212 extends toward the rear end of the door fitting portion 110 to prevent the above-mentioned situation from occurring, and the sealing function is performed while the cleaning is facilitated.

Further, in this embodiment, as shown in fig. 7 and 8, the groove 220 is provided with a mounting portion 221, the sealing strip body 211 is provided with a mounting groove 213, and the mounting portion 221 is clamped in the mounting groove 213, so that the sealing strip 210 is fixedly connected with the door body 200. With the arrangement, the sealing strip 210 can be more conveniently installed in the groove 220, which is beneficial to improving the production and assembly efficiency of the dishwasher. Of course, in other embodiments, the groove 220 may be provided with a mounting groove, the sealing strip body 211 is provided with a mounting portion, and the mounting portion may be clamped in the mounting groove, so that the sealing strip 210 and the door body 200 are fixedly connected more stably.

Further, in this embodiment, as shown in fig. 7 and 8, the mounting portion 221 has a hook-shaped structure, so that the mounting groove 213 of the weather strip body 211 can be more stably fixed to the mounting portion 221, and the weather strip 210 and the door body 200 are stably connected. In particular, the hook structure is bent in a direction approaching the base 100, so that the sealing tape 210 is further stably mounted to the door body 200.

Further, in the present embodiment, as shown in fig. 8, the weather strip body 211 has a cavity structure 214 to leave a suitable deformation space. In this way, when the sealing strip 210 is installed, the cavity structure 214 can be pressed by external force to further facilitate the sealing strip 210 to be installed in the groove 220, thereby further improving the production and assembly efficiency of the dishwasher; after the sealing strip body 211 is installed in the groove 220, the cavity structure 214 can be restored to its original shape without an external force, so that both ends of the sealing strip body 211 abut against the rear side of the blocking protrusion 300.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
