Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and particularly to a dishwasher. Background Art

[0002] As a practical kitchen appliance, a dishwasher can automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks.

[0003] The dishwasher includes an inner container and a door body rotatably installed at the open position of the inner container. A sealing strip is installed at a position of the inner container close to the opening, and a sealing flange is provided on the door body. When the door body closes the opening, the sealing flange squeezes the sealing strip to achieve the seal between the door body and the inner container, preventing the sprayed water or steam from spraying out between the door body and the inner container during the washing process of the dishwasher.

[0004] However, generally, the sealing flange is arranged on the door lining of the door body through a sheet metal stretching process. Limited by the sheet metal stretching process, at the corner of the bottom of the door lining, the sealing flange cannot fully cooperate tightly with the sealing strip, and the steam in the inner container is likely to overflow between the corner of the bottom of the door lining and the inner container. Summary of the Invention

[0005] Based on this, this application provides a dishwasher to solve the problem that the steam in the inner container in the related art is likely to overflow between the corner of the bottom of the door lining and the inner container.

[0006] An embodiment of this application provides a dishwasher, including:

[0007] An inner container with an opening;

[0008] A first sealing strip, including an installation section and a first extension section. The installation section is connected to the inner wall of the inner container, and the first extension section is located below the installation section and extends downward. The first extension section gradually approaches the opening from top to bottom;

[0009] A door body rotatably installed on the inner container to open or close the opening. A sealing flange protrudes on the door body. The sealing flange includes a first sealing section and a second sealing section connected to each other. The second sealing section is located on a side of the first sealing section facing the rotation axis of the door body;

[0010] Wherein, the inner container includes a chassis. Step portions are respectively arranged on opposite sides of the chassis. The step portion includes a first strengthening surface and a second strengthening surface that are connected. One end of the first strengthening surface away from the second strengthening surface extends to the side wall of the chassis. The side of the first extension section facing away from the opening abuts against the first strengthening surface;

[0011] When the door body closes the opening, the first sealing section squeezes the side of the installation section facing the opening, and the second sealing section squeezes the side of the first extension section facing the opening.

[0012] In a possible implementation, a water collecting groove that is recessed downward is provided in the middle of the chassis, and one end of the second reinforcing surface away from the first reinforcing surface extends to the edge of the water collecting groove.

[0013] In a possible implementation, both the first reinforcing surface and the second reinforcing surface gradually approach the opening from top to bottom. The edge of the opening defines a reference surface. The first reinforcing surface has a first angle with the reference surface in the longitudinal direction, and the second reinforcing surface has a second angle with the reference surface in the longitudinal direction. The first angle is less than or equal to the second angle.

[0014] In a possible implementation, when the door body closes the opening, the first reinforcing surface is parallel to the surface of the second sealing section facing the first extending section.

[0015] In a possible implementation, the chassis further includes a first bottom surface and a second bottom surface. The first bottom surface is located on one side of the side wall of the water collecting groove facing the inner container, and the stepped portion is connected to the first bottom surface. The second bottom surface is located on the side of the water collecting groove facing the opening;

[0016] A flow channel is defined between the stepped portion and the second bottom surface, and the flow channel is concave relative to the second bottom surface.

[0017] In a possible implementation, along the direction from the side wall of the inner container to the water collecting groove, both the first reinforcing surface and the second reinforcing surface gradually move away from the opening;

[0018] The edge of the opening defines a reference surface. The first reinforcing surface has a third angle with the reference surface in the transverse direction, and the second reinforcing surface has a fourth angle with the reference surface in the transverse direction. The third angle is less than the fourth angle.

[0019] In a possible implementation, the height of the first reinforcing surface gradually decreases along the direction from the side wall of the inner container to the second reinforcing surface, and the height of the second reinforcing surface gradually decreases along the direction from the first reinforcing surface to the water collecting groove.

[0020] In a possible implementation, the first sealing strip further includes a second extending section. The first end of the second extending section is connected to the bottom end of the first extending section. The second end of the second extending section extends towards the direction close to the opening, and the bottom surface of the second extending section abuts against the bottom surface of the chassis;

[0021] When the door body closes the opening, the end of the second sealing section away from the first sealing section presses against the top surface of the second extending section.

[0022] In a possible implementation, a second sealing strip is installed on the door body;

[0023] When the door body closes the opening, the middle part of the second sealing strip presses against the bottom surface of the chassis, and the end part of the second sealing strip presses against the top surface of the second extending section.

[0024] In a possible implementation, a sealing frame is installed on the inner wall of the inner container, and an installation groove is defined between the sealing frame and the inner wall of the inner container;

[0025] The installation section is embedded in the installation groove, and one side of the installation section facing away from the opening abuts against the bottom of the installation groove;

[0026] The first extension section extends out of the installation groove;

[0027] The distance between the first strengthening surface and the opening is less than the distance between the bottom of the installation groove and the opening.

[0028] The dishwasher provided by the present application includes an inner container, a first sealing strip and a door body. The first sealing strip includes an installation section and a first extension section, and the installation section is connected to the inner wall of the inner container. A sealing flange is convexly provided on the door body, and the sealing flange includes a first sealing section and a second sealing section. The inner container includes a chassis, and step portions are respectively arranged on opposite sides of the chassis. The step portions include a first strengthening surface and a second strengthening surface that are connected. One end of the first strengthening surface away from the second strengthening surface extends to the side wall of the chassis. One side of the first extension section facing away from the opening abuts against the first strengthening surface. Through the support of the first strengthening surface of the step portion on the first extension section, the first extension section gradually approaches the opening from top to bottom while extending downward. When the door body closes the opening, the first sealing section presses the side of the installation section facing the opening, and the second sealing section presses the side of the first extension section facing the opening. By providing the step portion, the space between the corner of the door body and the inner container can be reduced. The first strengthening surface of the step portion supports the first extension section of the first sealing strip. While the height of the second sealing section of the door body gradually decreases along the direction close to the rotation axis of the door body, it can ensure that the first extension section is closely attached to the inner container and the door body respectively, thereby reducing the risk of steam in the inner container overflowing from the corner between the bottom of the door liner and the inner container. In addition, the step portion can also strengthen the structural strength of the chassis, and the lower spray arm of the dishwasher can be more stable during washing. Description of the Drawings

[0046] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the accompanying drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals denote the same or similar components or components with the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of the present application. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0047] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection or an indirect connection through an intermediate medium, and may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0048] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is the orientation or positional relationship based on the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0049] The terms "first", "second", "third" (if any) in the description and claims of the present application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0050] In addition, the terms "include" and "have" and any deformation thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or display that includes a series of steps or units does not necessarily limit to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0051] In the prior art, a dishwasher includes an inner container and a door body rotatably installed at an open position of the inner container. A sealing strip is installed at a position of the inner container close to the open, and a sealing flange is provided on the door body. When the door body closes the open, the sealing flange presses the sealing strip to achieve the seal between the door body and the inner container, preventing the sprayed water or steam from spraying out between the door body and the inner container during the washing process of the dishwasher. However, the sealing flange is generally arranged on the door lining of the door body through a sheet metal stretching process. Limited by the sheet metal stretching process, the height of the bottom part of the sealing flange gradually decreases. At the corner of the bottom of the door lining, that is, the part where the bottom height of the sealing flange changes cannot be fully and closely matched with the sealing strip, and the steam in the inner container is likely to overflow between the corner of the bottom of the door lining and the inner container. The overflowed steam forms condensed water around the door body, resulting in water dripping, which affects the use experience of the dishwasher and is likely to cause the wooden cabinet to absorb water and deform.

[0052] After repeated thinking and verification, the inventor found that if step parts are respectively arranged on both sides of the bottom plate of the inner container, and a first strengthening surface and a second strengthening surface are arranged on the step parts, the step parts can strengthen the structural strength of the bottom plate, reduce the vibration of the lower spray arm during the washing of the dishwasher, and make the washing more stable. A sealing strip is installed at a position of the inner container close to the open. The distance between the side of the main body part of the sealing strip facing away from the open and the open is greater than the distance between the first strengthening surface and the open. The bottom part of the sealing strip is supported by the first strengthening surface of the step part, so that the bottom part of the sealing strip gradually approaches the open from top to bottom. In this way, when the door body of the dishwasher closes the open of the inner container, the part with gradually decreasing height of the sealing flange on the door body can press the bottom part of the sealing strip, reducing the risk of the steam in the inner container overflowing between the corner of the bottom of the door lining and the inner container.

[0053] In view of this, the inventor designed a dishwasher. By arranging step parts on the bottom plate of the inner container, the bottom part of the sealing strip on the inner container is supported by the first strengthening surface of the step part, so that this part gradually approaches the open of the inner container from top to bottom. When the door body closes the open of the inner container, the second sealing section of the sealing flange on the door body can reliably press the bottom part of the sealing strip, increasing the sealing performance between the corner of the bottom of the door lining and the inner container. The step part also includes a second strengthening surface, and the structural strength of the bottom plate of the inner container can also be improved through the step part.

[0054] The technical solutions of the dishwasher provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0055] Refer to Figures 1 to 12 As shown, the dishwasher provided in the embodiment of the present application includes an inner container 100, a first sealing strip 200 and a door body 300. The inner container 100 has an open 110, and the user can put tableware into the inside of the inner container 100 through the open 110.

[0056] The first sealing strip 200 includes an installation section 210 and a first extension section 220. The installation section 210 is connected to the inner wall of the inner container 100. The first extension section 220 is located below the installation section 210 and extends downward. The first extension section 220 gradually approaches the opening 110 from top to bottom. The first sealing strip 200 is disposed near the opening 110 of the inner container 100. Schematically, the installation section 210 is in an approximate "U" - shaped structure. The bottom edge of this "U" - shaped structure is connected to the inner top wall of the inner container 100, and the two side edges of the "U" - shaped structure are respectively connected to the two inner side walls of the inner container 100. Among them, the first extension sections 220 are respectively disposed below both ends of the installation section 210. The installation section 210 and the first extension section 220 can be connected by an integral molding method.

[0057] The door body 300 is rotatably installed on the inner container 100 to open or close the opening 110. Schematically, a column assembly 170 can be installed on the opening 110 of the inner container 100 by riveting. The column assembly 170 can include a top column, a left column, and a right column. Fixing plates can be respectively disposed at the bottoms of the left column and the right column, and rotating shafts can be disposed on the fixing plates. The door body 300 includes components such as a door liner 301, a hinge 330, a display board box, a left support of the door body, a right support of the door body, a dispenser, and a lock tongue. Fixing holes are provided on the hinge 330, and the fixing holes can be connected to the rotating shafts on the fixing plates, so that the door body 300 can rotate 0° - 90° around the axis of the rotating shaft.

[0058] A sealing flange 310 protrudes from the door body 300. The sealing flange 310 includes a first sealing section 311 and a second sealing section 312 that are connected to each other. The second sealing section 312 is located on the side of the first sealing section 311 facing the rotation axis of the door body 300. Among them, the sealing flange 310 can be disposed on the door liner 301 of the door body 300 by a stretching - forming method. The shape of the first sealing section 311 is also approximately "U" - shaped. The opening of this "U" - shaped faces the rotation axis of the door body 300. The sealing flange 310 can cooperate with the first sealing strip 200 to achieve the sealing between the inner container 100 and the door body 300. The number of the second sealing sections 312 is two, and the two second sealing sections 312 are respectively located at both ends of the first sealing section 311. It is worth mentioning that, in order to facilitate the stretching - forming of the sealing flange 310, the height of the second sealing section 312 gradually decreases from the first sealing section 311 to the direction of the rotation axis of the door body 300, and the end of the second sealing section 312 away from the first sealing section 311 has a smooth transition.

[0059] The inner liner 100 includes a chassis 120. Schematically, the inner liner 100 also includes a U-shaped plate 130 and a top plate 140, the top of the U-shaped plate 130 is engaged and fixed with the top plate 140, and the bottom of the U-shaped plate 130 is engaged and fixed with the chassis 120. Step portions 121 are respectively provided on opposite sides of the chassis 120. Schematically, the step portion 121 can be formed on the chassis 120 by stretching. The step portion 121 includes a first reinforcement surface 1211 and a second reinforcement surface 1212 connected to each other, and the end of the first reinforcement surface 1211 away from the second reinforcement surface 1212 extends to the side wall of the chassis 120, and the side of the first extension section 220 away from the opening 110 is against the first reinforcement surface 1211. The side of the first extension section 220 away from the opening is the second mounting bottom surface 221, and the second mounting bottom surface 221 is against the first reinforcement surface 1211.

[0060] It can be understood that the first reinforcement surfaces 1211 of the two step portions 121 respectively support the two first extension sections 220 of the first sealing strip 200 .

[0061] like Figure 11 As shown, the first reinforcement surface 1211 and the second reinforcement surface 1212 are arranged horizontally, and both the first reinforcement surface 1211 and the second reinforcement surface 1212 face the opening 110, and the first reinforcement surface 1211 and the second reinforcement surface 1212 can be connected by a transition surface 1215. It can be understood by those skilled in the art that the step portion 121 on the chassis 120 can support the chassis 120, thereby improving the structural strength of the chassis 120. After the first reinforcement surface 1211 abuts against the first extension section 220, it can support the first extension section 220, thereby preventing the first extension section 220 from moving in a direction away from the opening 110. The end of the first reinforcement surface 1211 extends to the side wall of the chassis 120, ensuring that the first reinforcement surface 1211 can reliably support the first extension section 220.

[0062] When the door body 300 closes the opening 110, the first sealing section 311 presses against the side of the installation section 210 facing the opening 110, and the second sealing section 312 presses against the side of the first extension section 220 facing the opening 110. That is to say, the first extension section 220 is located between the first strengthening surface 1211 and the second sealing section 312. The surface of the first sealing section 311 facing the inside of the inner container 100 is the first contact surface, and the surface of the second sealing section 312 facing the inside of the inner container 100 is the second contact surface. When the door body 300 closes the opening 110, the first sealing section 311 presses against the installation section 210 through the first contact surface, and the second sealing section 312 presses against the first extension section 220 through the second contact surface. Among them, the first sealing strip 200 is made of an elastic material. For example, the first sealing strip 200 can be an extruded rubber part. The first sealing strip 200 has a certain plasticity. After the first sealing strip 200 is installed on the inner container 100, the installation section 210 and the first extension section 220 are formed. The installation section 210 and the first extension section 220 of the first sealing strip 200 can both undergo elastic deformation after being pressed, and the sealing between the inner container 100 and the door body 300 is achieved through the elastic deformation of the first sealing strip 200. Here, the surface of the first sealing strip 200 for cooperating with the door body 300 is defined as the sealing surface 240. The setting of the first strengthening surface 1211 of the step portion 121 reduces the gap between the inner container 100 and the corner of the door lining 301. The first extension section 220 between the first strengthening surface 1211 and the second sealing section 312 is stably pressed by both of them, and the sealing surface 240 is in close contact with the second sealing section 312 at the position of the first extension section 220 to achieve stable sealing.

[0063] The dishwasher provided in this embodiment, its first sealing strip 200 includes an installation section 210 and a first extension section 220. Step portions 121 are respectively arranged on opposite sides of the chassis 120. The step portion 121 includes an adjacent first strengthening surface 1211 and a second strengthening surface 1212. One end of the first strengthening surface 1211 away from the second strengthening surface 1212 extends to the side wall of the chassis 120. The side of the first extension section 220 facing away from the opening 110 abuts against the first strengthening surface 1211. Through the support of the first strengthening surface 1211 of the step portion 121 on the first extension section 220, the first extension section 220 gradually approaches the opening 110 from top to bottom while extending downward. When the door body 300 closes the opening 110, the first sealing section 311 presses the side of the installation section 210 facing the opening 110, and the second sealing section 312 presses the side of the first extension section 220 facing the opening 110. By providing the step portion 121, the space size between the corner of the door body 300 and the inner container 100 can be reduced. The first strengthening surface 1211 of the step portion 121 supports the first extension section 220 of the first sealing strip 200. While the height of the second sealing section 312 of the door body 300 gradually decreases along the direction close to the rotation axis of the door body 300, it can ensure that the first extension section 220 is closely attached to both the inner container 100 and the door body 300 respectively, thereby reducing the risk of steam in the inner container 100 overflowing from the corner between the bottom of the door liner 301 and the inner container 100. Steam is not likely to overflow, resulting in problems such as energy loss of the dishwasher, water dripping around the door body, and deformation of the wooden cabinet. In addition, the step portion 121 can also strengthen the structural strength of the chassis 120, and the lower spray arm of the dishwasher can be more stable during washing.

[0064] In one embodiment, as Figures 1 - 12 shown, a sealing frame 150 is installed on the inner wall of the inner container 100. An installation groove 160 is defined between the sealing frame 150 and the inner wall of the inner container 100. Among them, the sealing frame 150 can be fixed to the inner wall of the inner container 100 by riveting. In a possible implementation manner, the sealing frame 150 includes a first connection section and a second connection section that are perpendicular to each other. Both the first connection section and the second connection section are sheet-like structures. The inner wall of the inner container 100 is located on the side of the first connection section facing away from the second connection section. The cross-sectional shape of the installation groove 160 can be U-shaped, and the opening of this U-shape faces the opening 110.

[0065] The installation section 210 is embedded in the installation groove 160, and one side of the installation section 210 facing away from the opening 110 abuts against the bottom of the installation groove 160. Among them, the side walls on both sides of the installation groove 160 can generate a squeezing force on the installation section 210 of the first sealing strip 200, thereby fixing the installation section 210 and the installation groove 160. The surface of the installation section 210 facing away from the opening 110 is the first installation bottom surface 211, and the bottom wall of the installation groove 160 can support the first installation bottom surface 211, so that the installation section 210 is in close contact with the first sealing section 311 of the sealing flange 310 to achieve a sealing effect.

[0066] The first extension section 220 extends out of the installation groove 160. The first strengthening surface 1211 is located at the extension of the installation groove 160. The distance between the first strengthening surface 1211 and the opening 110 is less than the distance between the bottom of the installation groove 160 and the opening 110. That is to say, the first strengthening surface 1211 is closer to the opening 110 than the bottom of the installation groove 160. Furthermore, the step portion 121 can reduce the space size between the corner of the door body 300 and the inner tank 100 at the position of the first strengthening surface 1211.

[0067] With this structure, the installation section 210 of the first sealing strip 200 can be reliably fixed on the inner wall of the inner tank 100 through the sealing frame 150. The first strengthening surface 1211 is closer to the opening 110 than the bottom of the installation groove 160, ensuring that the first extension section 220 is in close contact with the inner tank 100 and the door body 300 respectively, thereby reducing the risk of steam in the inner tank 100 overflowing from the corner between the bottom of the door liner 301 and the inner tank 100.

[0068] It is worth mentioning that since a sliding groove is provided at the bottom of the inner tank 100, the bottom wall of the installation groove 160 cannot extend below the slideway 126. The dishwasher provided in this application provides a supporting force for the bottom of the first sealing strip 200 through the first strengthening surface 1211. The first strengthening surface 1211 is provided on the step portion 121, and the step portion 121 is provided below the slideway 126, playing the role of extending the bottom wall of the installation groove 160, thereby improving the sealing effect at the corner of the door body 300 and reducing the risk of air leakage.

[0069] In one embodiment, as Figure 11 shown, the middle of the chassis 120 has a downwardly concave water collecting groove 122, and one end of the second strengthening surface 1212 away from the first strengthening surface 1211 extends to the edge of the water collecting groove 122.

[0070] Among them, the cross-sectional shape of the water collecting tank 122 can be a suitable shape such as square or circular. The water collecting tank 122 can be provided in the middle of the chassis 120 through a stretching process. Those skilled in the art can understand that the water collecting tank 122 is at the lowest position of the chassis 120. During the cleaning process of the dishwasher, the washing liquid can flow back to the water collecting tank 122 for reuse. One end of the second reinforcing surface 1212 away from the first reinforcing surface 1211 can extend in a direction away from the opening 110 and extend to the edge of the water collecting tank 122. That is to say, the second reinforcing surface 1212 starts from the end of the first reinforcing surface 1211 and ends at the water collecting tank 122.

[0071] With the above settings, the length of the second reinforcing surface 1212 is relatively long, which is beneficial to further strengthening the structural strength of the chassis 120. Moreover, the first reinforcing surface 1211 and the second reinforcing surface 1212 of the step portion 121 can also play a role in guiding the flow, that is, the washing water can flow to the water collecting tank 122 along the first reinforcing surface 1211 and the second reinforcing surface 1212.

[0072] In a specific embodiment, as Figure 7 、 Figure 8 and Figure 11 shown, both the first reinforcing surface 1211 and the second reinforcing surface 1212 gradually approach the opening 110 from top to bottom. The edge of the opening 110 defines a reference surface. The first reinforcing surface 1211 has a first included angle with the reference surface in the longitudinal direction, and the second reinforcing surface 1212 has a second included angle with the reference surface in the longitudinal direction. The first included angle is less than or equal to the second included angle.

[0073] Among them, the first reinforcing surface 1211 and the second reinforcing surface 1212 can be inclined surfaces respectively. That is to say, the first reinforcing surface 1211 forms a first included angle with the reference surface in the up and down direction, and the size of the first included angle is a1. The second reinforcing surface 1212 forms a second included angle with the reference surface in the up and down direction, and the size of the second included angle is b1, and a1 ≤ b1. It can be understood that the smaller the included angle between the reinforcing surface and the reference surface, the steeper the reinforcing surface. The second reinforcing surface 1212 is not steeper than the first reinforcing surface 1211. The present embodiment does not limit the respective sizes of the first included angle and the second included angle, and those skilled in the art can set them according to actual needs.

[0074] With the above settings, the sealing between the first reinforcing surface 1211 and the second contact surface of the second sealing section 312 can be made tighter through the first extension section 220. At the same time, the second reinforcing surface 1212 is not steeper than the first reinforcing surface 1211, the second reinforcing surface 1212 is more convenient for stretching and forming, and the position of the step portion 121 corresponding to the second reinforcing surface 1212 does not affect the stretching and forming of the bottom of the inner liner 100.

[0075] In a possible implementation, when the door body 300 closes the opening 110, the first strengthening surface 1211 is parallel to the surface of the second sealing section 312 facing the first extension section 220. That is to say, when the door body 300 closes the opening 110, the first strengthening surface 1211 is parallel to the second contact surface.

[0076] In other embodiments, the first strengthening surface 1211 may also be approximately parallel to the second contact surface. For example, the angle between the first strengthening surface 1211 and the second contact surface does not exceed 5 degrees.

[0077] Through the above settings, when the door body 300 closes the opening 110, the second contact surface can squeeze the first extension section 220 more evenly, so that the compression amount of the first extension section 220 is more uniform, ensuring stable sealing between the first strengthening surface 1211 and the second sealing section 312.

[0078] As Figure 8 、 Figure 9 and Figure 11 As shown, the chassis 120 further includes a first bottom surface 123 and a second bottom surface 124. The first bottom surface 123 is located on one side of the side wall of the water collecting tank 122 facing the inner tank 100, and the step portion 121 is connected to the first bottom surface 123. The second bottom surface 124 is located on the side of the water collecting tank 122 facing the opening 110. Among them, the number of the first bottom surfaces 123 is two, and the two first bottom surfaces 123 are respectively located on the left and right sides of the water collecting tank 122. The second bottom surface 124 is located on the front side of the water collecting tank 122. Figure 11 It is shown that the front end of the first bottom surface 123 is connected to the first strengthening surface 1211 through a first transition angle 1213, and the front end of the first bottom surface 123 is connected to the second strengthening surface 1212 through a second transition angle 1214.

[0079] A flow channel 125 is defined between the step portion 121 and the second bottom surface 124, and the flow channel 125 is concave relative to the second bottom surface 124. Specifically, both the first bottom surface 123 and the second bottom surface 124 are higher than the flow channel 125. The chassis 120 can form the flow channel 125 by stretching, and the depth of the flow channel 125 can match the height of the corresponding position of the step portion 121. During the washing process of the dishwasher, the flow channel 125 can enable the washing liquid to quickly flow back to the water collecting tank 122, making the washing more stable. Optionally, one end of the flow channel 125 is connected to a corner of the chassis 120, which is the position of the chassis 120 farthest from the water collecting tank 122, and the other end of the flow channel 125 is connected to the water collecting tank 122. By setting the flow channel 125, the washing liquid can quickly flow back, thereby improving the utilization efficiency of the washing liquid, enhancing the washing effect and reducing the overall amount of the washing liquid.

[0080] In a possible implementation, as Figure 7 、 Figure 8 andFigure 11 As shown, in the direction from the side wall of the inner tank 100 to the water collecting tank 122, both the first strengthening surface 1211 and the second strengthening surface 1212 gradually move away from the opening 110. Taking Figure 11 the stepped portion 121 on the left side in the figure as an example, both the first strengthening surface 1211 and the second strengthening surface 1212 gradually extend backward from left to right.

[0081] The edge of the opening 110 defines a reference surface. The first strengthening surface 1211 has a third included angle with the reference surface in the transverse direction, and the second strengthening surface 1212 has a fourth included angle with the reference surface in the transverse direction. The third included angle is smaller than the fourth included angle. Specifically, the first strengthening surface 1211 has a third included angle with the left - right direction, and the magnitude of the third included angle is a2. The second strengthening surface 1212 has a fourth included angle with the left - right direction, and the magnitude of the fourth included angle is b2, where a2 < b2. Among them, a slideway 126 extending in the front - rear direction is provided on the chassis 120. The first strengthening surface 1211 forms an acute angle with the vertical plane of the slideway 126, and the two stepped portions 121 on the chassis 120 are in the shape of an open flared trumpet. In this embodiment, there is no limitation on the respective magnitudes of the third included angle and the fourth included angle, and those skilled in the art can set them as needed.

[0082] In this embodiment, the magnitude of the fourth included angle is set relatively large to facilitate ensuring that the washing liquid can flow smoothly in the flow channel 125. The magnitude of the third included angle is designed to be smaller than the fourth included angle in order to ensure the seal between the inner tank 100 and the door body 300 while taking into account the smooth flow of the washing liquid in the flow channel 125. That is to say, the above - mentioned setting can both ensure the smooth flow of the washing liquid in the flow channel 125 and ensure the sealing effect between the corner at the bottom of the door liner 301 and the inner tank 100.

[0083] In a possible implementation manner, as Figure 11 shown, the height of the first strengthening surface 1211 gradually decreases in the direction from the side wall of the inner tank 100 to the second strengthening surface 1212, and the height of the second strengthening surface 1212 gradually decreases in the direction from the first strengthening surface 1211 to the water collecting tank 122. That is to say, the height of the stepped portion 121 gradually decreases in the direction from the edge of the chassis 120 to the middle of the chassis 120. For example Figure 11 as shown in the figure, the height of the left - hand first bottom surface 123 gradually decreases from left to right. Schematically, the height of the second bottom surface 124 gradually decreases from front to back. Optionally, the first bottom surface 123 decreases successively from front to back, that is, the front side of the first bottom surface 123 is higher than the rear side of the first bottom surface 123.

[0084] Through the above settings, the height of the first reinforcing surface 1211 can be ensured, which is beneficial to improving the sealing effect between the corner at the bottom of the door liner 301 and the inner liner 100. The height of the second reinforcing surface 1212 gradually decreases in the direction from the edge to the center of the chassis 120, which can ensure that the stepped portion 121 can be smoothly drawn and formed. In addition, the first bottom surface 123 can also play a role in draining the cleaning liquid thereon, so that the cleaning liquid on the first bottom surface 123 can flow to the water collecting tank 122.

[0085] In one embodiment, as Figures 1 - 12 shown, the first sealing strip 200 further includes a second extension section 230. The first end of the second extension section 230 is connected to the bottom end of the first extension section 220, the second end of the second extension section 230 extends in the direction close to the opening 110, and the bottom surface of the second extension section 230 abuts against the bottom surface of the chassis 120. Among them, the bottom surface of the second extension section 230 is the third mounting bottom surface 231, and the third mounting bottom surface 231 abuts against the bottom surface of the chassis 120. Specifically, the mounting section 210, the first extension section 220 and the second extension section 230 form an integral part, and the second extension section 230 is located at one end of the first extension section 220 away from the mounting section 210. The second extension section 230 extends in the front-rear direction, and the rear end of the second extension section 230 is connected to the lower end of the first extension section 220. When the chassis 120 is provided with a flow channel 125, the bottom surface of the second extension section 230 abuts against the bottom surface of the flow channel 125.

[0086] When the door body 300 closes the opening 110, the end of the second sealing section 312 away from the first sealing section 311 presses against the top surface of the second extension section 230. Among them, the end of the second sealing section 312 away from the first sealing section 311 is the lower edge 313 of the second sealing section 312. When the opening angle of the door body 300 gradually changes from 90° to 0°, the lower edge 313 of the second sealing section 312 gradually presses down on the second extension section 230 and finally has an interference fit with the second extension section 230 to achieve a sealing effect.

[0087] Through the above settings, the sealing effect between the corner at the bottom of the door liner 301 and the inner liner 100 is further improved.

[0088] In one embodiment, a second sealing strip 320 is installed on the door body 300. Among them, the second sealing strip 320 is arranged close to the rotation axis of the door body 300, and the extending direction of the second sealing strip 320 is parallel to the rotation axis of the door body 300. The second sealing strip 320 is made of an elastic material and can undergo elastic deformation when being squeezed.

[0089] When the door body 300 closes the opening 110, the middle part of the second sealing strip 320 presses against the bottom surface of the chassis 120, and the end part of the second sealing strip 320 presses against the top surface of the second extension section 230. When the opening angle of the door body 300 is 90°, that is, when the door body 300 is fully opened, the distance between the first sealing strip 200 and the second sealing strip 320 is the farthest. When the door body 300 closes the opening 110, the first sealing strip 200 and the second sealing strip 320 form an annular structure surrounding the inner wall of the inner container 100, and the first sealing strip 200 and the second sealing strip 320 jointly seal the gap between the inner container 100 and the door body 300. When the opening angle of the door body 300 gradually changes from 90° to 0°, the position of the second sealing strip 320 near the end gradually presses down on the second extension section 230.

[0090] Through the above settings, the sealing effect between the corner at the bottom of the door liner 301 and the inner container 100 is further improved.

[0091] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
