[0052] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail with reference to the accompanying drawings.

[0053] ​​The description of the lower part relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0054] In the description of the present application, it is understood that the terms "first", "second" and the like are used only for descriptive purposes and cannot be understood as indicating or implying relative importance. For those skilled in the art, the specific meaning of the above terms in the present application can be understood in specific cases.

The character " / " generally represents the relationship between the front and rear associated objects as "or".

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0056] The present application proposes a dishwasher 1 which can effectively remove food residues on the surface of tableware (bowls, plates, etc.), and disinfect and sterilize tableware during cleaning, and after cleaning and disinfection, the tableware will be dried. Among them, disinfection and sterilization can add cleaning liquid to the water for cleaning tableware, and control the internal environment of the dishwasher 1 (including the water temperature of the cleaning liquid) to be about 70℃-85℃, at this temperature, the activity of common pathogenic microorganisms such as Escherichia coli and Staphylococcus aureus will be inhibited or even killed, thereby ensuring the hygiene of tableware. The drying method of the dishwasher 1 can be heat exchange drying, hot air drying, etc., which can effectively prevent tableware from breeding bacteria and producing odor due to moisture.

[0057] In the related art, please refer to Figure 1 and Figure 2As shown, the dishwasher 1 comprises a tub 15, a partition 16 and a door body 103. The tub 15 has a washing cavity 153, the partition 16 is assembled in the washing cavity 153 to divide the washing cavity 153 into an upper washing cavity 1531 and a lower washing cavity 1532, and the door body 103 is movably connected with the tub 15 and is used to at least open and close the upper washing cavity 1531. Generally, the door body 103 can be connected with the tub 15 through a hinge, so that the door body 103 has better stability and buffering effect when being opened and closed, and the position and angle of the door body 103 can be adjusted as needed. Since the movably connection between the door body 103 and the tub 15 is a mature prior art in the field, and the application does not make significant improvements to the connection method, the embodiment will not be described in detail.

[0058] On the one hand, the partition 16 divides the washing cavity 153 into the relatively independent upper washing cavity 1531 and lower washing cavity 1532, which can better meet the cleaning needs of different amounts of tableware. When the user has a large amount of tableware to be cleaned, the upper washing cavity 1531 and the lower washing cavity 1532 can be used at the same time, which increases the total washing space and improves the space utilization, and is no longer limited by a single large-capacity washing cavity.

[0059] On the other hand, the independent upper washing cavity 1531 and lower washing cavity 1532 make the cleaning process more clear. During the washing process, the two washing cavities can work in parallel, which shortens the overall washing time. Moreover, when one washing cavity fails or needs maintenance, the other washing cavity can still be used normally, which will not affect the user's daily tableware cleaning needs.

[0060] However, due to assembly errors between the door body 103 and the partition 16 during actual production and assembly, assembly gaps may exist between the two, or due to long-term bearing of temperature changes and water pressure inside the dishwasher 1, the tub 15 deforms, causing deformation gaps between the door body 103 and the partition 16, so that the parts between the door body 103 and the partition 16 are prone to leakage during the cleaning process of the tableware.

[0061] Based on the above easily overlooked problems, the inventor provides a preferred technical manner, which is specifically described in combination with Figure 2 and Figure 3 As shown, the dishwasher 1 further comprises a front sealing member 191, which is arranged on the front side of the partition 16 and extends in the left-right direction, and the door body 103 is in interference fit with the front sealing member 191 when the door body 103 closes the upper washing cavity 1531. It can be understood that in the dishwasher 1, when the user faces the dishwasher 1 to normally operate the dishwasher 1, the direction facing the user is the front, and the side of the partition 16 closer to the door body 103 of the dishwasher 1, that is, the side closer to the user's operating surface, is defined as the front side of the partition 16.

[0062] Thus, the following unexpected technical effects can be achieved:

[0063] Firstly, the assembly gap between the door body 103 and the partition 16 is inevitable due to the assembly error in actual production and assembly. The front seal 191 can fill the assembly gap. When the door body 103 is closed, the front seal 191 is in interference fit, which can effectively fill the gap caused by the assembly error. Alternatively, the inner container 15 will deform under the long-term effect of temperature change and water pressure inside the dishwasher 1, thereby causing deformation gap between the door body 103 and the partition 16. The front seal 191 has certain elasticity and adaptability. Even in the case of gap between the door body 103 and the partition 16 due to the deformation of the inner container 15, the front seal 191 in interference fit can still maintain good sealing state by deforming itself to adapt to the change, prevent water from leaking from the assembly gap, improve the sealing performance of the dishwasher 1, and ensure that the water flow does not leak from between the door body 103 and the partition 16 during the cleaning process. Not only the washing effect is guaranteed, but also the service life of the dishwasher 1 is prolonged, and the repair cost caused by leakage is reduced.

[0064] Secondly, the front seal 191 extends along the front side of the partition 16 in the left-right direction, and can form a continuous sealing line between the door body 103 and the partition 16 when the door body 103 is closed. Compared with the case without the front seal 191, this continuous sealing structure can more evenly withstand the internal water pressure and external pressure, making the sealing effect more stable and reliable. No matter in the cleaning, disinfection or drying of the dishwasher 1, the sealing property between the door body 103 and the partition 16 can be better guaranteed, and the risk of leakage is reduced.

[0065] It should be noted that the above-mentioned inner container 15 includes an upper inner container 151 and a lower inner container 152, wherein the upper inner container 151 includes an upper inner container top wall, an upper inner container back wall and an upper inner container side wall, the number of the upper inner container side wall is configured as two, the two upper inner container side walls are oppositely arranged and are both vertically connected to the upper inner container top wall, the upper inner container top wall is preferably integrally formed with the two upper inner container side walls, the upper inner container back wall is preferably integrally formed with the upper inner container top wall and is fixedly connected to the upper inner container side wall. The above-mentioned lower inner container 152 includes a lower main body, the lower main body includes a lower inner container bottom wall, a lower inner container side wall and a lower inner container back wall, the number of the lower inner container side wall is configured as two, the two lower inner container side walls are oppositely arranged and are both vertically connected to the lower inner container top wall, the partition 16 is located between the upper inner container top wall and the lower inner container bottom wall, and the upper inner container top wall and the lower inner container bottom wall are oppositely arranged with the partition 16.

[0066] Define one of the two upper inner liner sidewalls as the upper left sidewall and the other as the upper right sidewall. Define one of the two lower inner liner sidewalls as the lower left sidewall and the other as the lower right sidewall. The upper left sidewall and the lower left sidewall are coplanar, and the upper right sidewall and the lower right sidewall are coplanar. Coplanar means that they are in the same plane. Specifically, in the vertical direction, the upper left sidewall and the lower left sidewall are in the same plane, and the upper right sidewall and the lower right sidewall are in the same plane. Therefore, the "left-right direction" of the front seal 191 extending along the front left-right direction of the separator 16 is the direction towards the side where the upper left sidewall and the upper right sidewall are located.

[0067] In some embodiments, the upper inner liner back wall, upper inner liner side wall, lower inner liner side wall, and lower inner liner back wall are all inserted into and connected to the separator 16. In other embodiments, the upper inner liner side wall and the lower inner liner side wall may be integrally formed as an inner liner side wall, with the inner liner side wall being a separately formed workpiece; that is, the upper left side wall and the lower left side wall are integrally formed, and the upper right side wall and the lower right side wall are integrally formed. The upper inner liner back wall and the lower inner liner back wall are integrally formed as an inner liner back wall, with the inner liner back wall being a separately formed workpiece. Both the inner liner side wall and the inner liner back wall are sealed to the separator 16; this sealing connection should be understood as at least one of adhesive bonding and welding.

[0068] As a preferred embodiment, please refer to the following for details. Figure 3 and Figure 6 As shown, a first protrusion 1031 is formed on one side of the door body 103 facing the washing chamber 1531. This protrusion is preferably formed using a bending process, and the front seal 191 abuts against the bottom of the first protrusion 1031. Thus, the first protrusion 1031 provides a specific abutment position for the front seal 191, allowing for a more even distribution of the contact area and pressure between the bottom of the first protrusion 1031 and the front seal 191. This better fills any gaps that may exist between the door body 103 and the partition 16, effectively enhancing the sealing performance and preventing water leakage from the inside of the dishwasher 1.

[0069] Meanwhile, the first protrusion 1031 increases the structural strength and rigidity of the door 103 at this location. When the door 103 is closed, the front seal 191 abuts against the bottom of the first protrusion 1031, which not only provides a sealing function but also supports and positions the door 103 to a certain extent. This makes the door 103 more stable when subjected to the water pressure inside the dishwasher 1 and other external forces, reducing deformation and shaking of the door 103 and extending the service life of the door 103 and the entire dishwasher 1.

[0070] Furthermore, please refer to the specific details. Figure 3 and Figure 6As shown, the top of the first protruding part 1031 is provided with a water guide top surface 10311, which is preferably a plane, and the water guide top surface 10311 is inclined to the door body 103 and extends towards the side of the partition 16. This can effectively change the direction of the water flow, so that the water that may flow to the top of the first protruding part 1031 quickly flows to the partition 16 along the water guide top surface 10311, avoiding the accumulation of water on the top of the first protruding part 1031 of the door body 103, and reducing the risk of leakage.

[0071] It should be noted that, please refer to Figure 3 , the included angle between the water guide top surface 10311 and the horizontal plane is κ, κ is not less than 5° and not greater than 75°. In this way, the water flow can quickly flow to the side of the partition 16 under the dual action of gravity and the water guide top surface 10311, which not only ensures the drainage efficiency, but also avoids the accumulation or formation of reverse impact of strong water flow near the door body 103, thereby enhancing the waterproof performance of the door body 103 in a complex water flow environment. If κ < 5°, the angle is too small, and the water guide top surface 10311 is almost horizontal. The speed of water flowing along the water guide top surface 10311 under the action of gravity will be very slow, which can easily lead to the accumulation of water on the water guide top surface 10311, and cannot be drained in time, thereby increasing the risk of water leakage from between the door body 103 and the partition 16. At the same time, the accumulated water can affect the cleaning effect inside the dishwasher 1, so that some dirt and residual substances cannot be discharged with the water flow, but are attached to the door body 103 or other components, which can breed bacteria over a long period of time, thereby affecting the hygiene of the dishwasher 1. If κ > 75°, the flow rate of the water flow on the water guide top surface 10311 will be too fast, which can generate a large impact force on the partition 16 or other components inside the dishwasher 1, which can cause damage to these components over a long period of time, thereby affecting the normal service life of the dishwasher 1. At the same time, the high-speed water flow can splash when reaching the partition 16 or other components, thereby affecting the hygiene of the washing cavity 153.

[0072] Preferably, as shown in Figure 2 and Figure 3 , the partition 16 is provided with a front sealing groove 182, and the front sealing member 191 is embedded in the front sealing groove 182, and part of the front sealing member 191 protrudes out of the front sealing groove 182 and is in interference fit with the door body 103. In this way, the front sealing groove 182 provides a precise installation position for the front sealing member 191, so that during installation, the front sealing member 191 only needs to be embedded in the groove, thereby reducing the installation difficulty, improving the assembly efficiency and positioning accuracy, and being helpful to realize standardized and large-scale production. At the same time, the front sealing groove 182 can fix and protect the front sealing member 191, and embedding the front sealing member 191 in the groove can avoid direct friction or collision between the front sealing member 191 and other components during the operation of the dishwasher 1, thereby reducing the probability of wear and tear and displacement of the front sealing member 191, prolonging the service life of the front sealing member 191, and ensuring the long-term stability of the sealing function.

[0073] It should be noted that the groove depth size Hi of the front sealing groove 182 is not less than 5 and not greater than 25 mm, which can ensure that the front sealing member 191 has sufficient embedding depth, so that the front sealing member 191 is in full contact with the groove wall of the front sealing groove 182 to form an effective sealing line, and ensure that the front sealing member 191 can protrude from the front sealing groove 182 to fit with the first protruding part 1031. At the same time, it is also convenient for processing and forming. When the groove depth size Hi < 5 mm, the groove depth of the front sealing groove 182 is too shallow, and the front sealing member 191 cannot be firmly embedded in the groove. During the operation of the dishwasher 1, the front sealing member 191 is prone to displacement and falling off, resulting in sealing failure. It also cannot provide sufficient support for the front sealing member 191, so that the front sealing member 191 is prone to deformation when subjected to external pressure, further affecting the sealing performance. When the groove depth size Hi > 25 mm, the groove depth of the front sealing groove 182 is too deep, which is difficult to process and requires higher processing precision and process requirements, increasing the processing cost and production cycle.

[0074] Further, please refer to Figure 3 The front sealing member 191 includes a front rubber strip body 1911. Along the groove depth direction Ti of the front sealing groove 182, the first height hi of the front rubber strip body 1911 is greater than the groove depth size Hi, so that after the front sealing member 191 is installed into the front sealing groove 182, part of the front rubber strip body 1911 will protrude from the front sealing groove 182, thereby forming an interference fit with the door body 103 and other components. The first height hi is not less than 6 and not greater than 30 mm, which can not only ensure the sealing performance of the front sealing member 191, but also reasonably control the amount of material and reduce the cost of material. At the same time, the appropriate height is also conducive to maintaining good elasticity and flexibility of the front sealing member 191, so that it is not prone to aging and hardening during long-term use, thereby prolonging the service life. In addition, when the front sealing member 191 cooperates with the front sealing groove 182, it can better fill the gap and achieve the best interference fit effect, and will not be excessively extruded due to being too high, thereby causing the front sealing member 191 to fail prematurely.

[0075] If the first height hi < 6 mm, the height of the front sealing member 191 is too low, and the elastic deformation amount is insufficient, so that it cannot effectively fill the gap between the components. During the operation of the dishwasher 1, it is prone to occur that the sealing is not tight. Moreover, the contact area between the front sealing member 191 and the door body 103 / the first protruding part 1031 is small, resulting in poor sealing effect. If the first height hi > 30 mm, the front sealing member 191 is too high, which on the one hand increases the cost of material, and on the other hand, it may be difficult to smoothly embed into the front sealing groove 182 during installation. When cooperating with the door body 103, it may be excessively extruded, so that the front sealing member 191 bears excessive pressure and is severely deformed, or even damaged, thereby shortening the service life of the front sealing member 191.

[0076] Further, please refer to Figure 3 , the front seal 191 further comprises a first drainage portion 1912, which extends upwardly from the top of the front rubber strip body 1911 to the bottom of the first protruding portion 1031, specifically, the first drainage portion 1912 is located at the end of the front rubber strip body 1911 protruding the front sealing groove 182, and the first drainage portion 1912 is fixedly connected with the front rubber strip body 1911, and the fixed connection here is preferably integrated.

[0077] On the one hand, the first drainage portion 1912 is tightly fitted with the first protruding portion 1031, so as to realize the purpose of abutting the front seal 191 with the first protruding portion 1031 to form a sealing defense line. On the other hand, the first drainage portion 1912 can also guide the water flow along its inclined surface to the partition 16, avoiding the accumulation of water near the front seal 191, further enhancing the waterproof effect, thereby facilitating the improvement of the washing effect.

[0078] It should be noted that, please refer to Figure 3 , the first drainage portion 1912 forms an angle εi with the horizontal plane, and εi is not less than 5° and not greater than 75°. In this way, it can be ensured that the first drainage portion 1912 has sufficient inclination to guide the water flow and smoothly drain the residue, while ensuring that the first drainage portion 1912 is not too steep to prevent the water flow from impacting the internal structure of the dishwasher 1, and facilitating manufacturing and installation, and ensuring the cooperation precision between the first drainage portion 1912 and the first protruding portion 1031. If εi < 5°, the slope of the first drainage portion 1912 is insufficient, the water flow cannot be smoothly drained, and is easy to accumulate in the first drainage portion 1912, resulting in a decrease in sealing performance. If εi > 75°, the slope of the first drainage portion 1912 is too large, resulting in too fast water flow, which may impact the internal structure of the dishwasher 1, and increase the difficulty of manufacturing and installation.

[0079] Further, please refer to Figure 3 , the front seal 191 further comprises a first extension portion 1913, which extends from the front rubber strip body 1911 and is inclined to the center line of the front rubber strip body 1911, and the first extension portion 1913 is preferably inclined upward, wherein the first extension portion 1913 is preferably configured as a plurality of first extension portions 1913, and the plurality of first extension portions 1913 are evenly arranged and distributed on the front rubber strip body 1911 along the center line of the front rubber strip body 1911, the first extension portion 1913 abuts the inner groove wall of the front sealing groove 182, and the first extension portion 1913 is fixedly connected with the front rubber strip body 1911, and the fixed connection here is preferably integrated.

[0080] In this way, the first extension 1913, which is upwardly inclined, can naturally guide the front seal 191 when the front seal 191 is installed. When the front seal 191 is placed in the front seal groove 182, the first extension 1913 first contacts the groove wall of the front seal groove 182, and the inclined shape guides the seal to accurately slide into the groove. At the same time, since the first extension 1913 has a certain elasticity, even if there is a slight deviation in the size of the front seal groove 182 during installation, the first extension 1913 can be self-adapted by deforming itself. They can slightly bend or contract when pressed by the groove wall of the front seal groove 182, so that the front seal 191 can be smoothly installed in place, greatly reducing the difficulty and time of alignment during installation, and improving the installation efficiency.

[0081] It should be added that the included angle between the first extension 1913 and the center line of the front rubber strip body 1911 is θ1, which is not less than 90° and not greater than 150°. In this way, the first extension 1913 of the front seal 191 can be effectively ensured to remain in a relatively relaxed state during installation, fully exerting its guiding and self-adaptive adjustment functions, and forming good contact with the inner groove wall of the front seal groove 182, effectively guiding the seal to be installed in place, while maintaining stable sealing performance during operation of the dishwasher 1. When θ < 90°, the first extension 1913 cannot effectively guide during installation, and the angle is too small to effectively abut the groove wall, affecting the sealing effect. When θ > 150°, the first extension 1913 is too steep, and during installation, it is easy to bend too much in the groove, and even possibly broken, affecting installation and use.

[0082] It should be added that along the groove width direction Tb of the front seal groove 182, the width dimension of the front seal 191 is a first width bi, and the groove width dimension Bi of the front seal groove 182 is less than the first width bi. In this way, the wider front seal 191 can better fill the front seal groove 182, so that the front seal 191 and the front seal groove 182 form an interference fit, and even if affected by external forces such as water flow impact and dishwasher 1 vibration during washing, the front seal 191 can always be tightly attached to the groove wall of the front seal groove 182, effectively blocking water leakage, ensuring the sealing between the upper washing chamber 1531 and the lower washing chamber 1532, and ensuring that the washing effect is not affected. At the same time, in the actual production process, there may be certain manufacturing errors in each part of the dishwasher 1, and the groove width dimension Bi is also difficult to be completely consistent. The groove width dimension Bi is less than the first width bi, which can effectively compensate for these errors. Even if the groove width dimension Bi is slightly larger than the standard size, the wider front seal 191 can still achieve good sealing, improving the universality and stability of the product.

[0083] The groove width size Bi is not less than 3 mm and not greater than 20 mm, which ensures that the front sealing member 191 has enough space for installation, guarantees the integrity and normal operation of the front sealing member 191, avoids the problems of difficult installation or deformation of the front sealing member 191 due to too narrow space or looseness due to too wide space, and affects the sealing effect. When the groove width size Bi < 3 mm, the front sealing groove 182 is too narrow, and the front sealing member 191 is difficult to install in place, and even if it is forced to install, it is easy to be deformed due to extrusion, and cannot play a normal sealing role, greatly increasing the risk of water leakage. In addition, the front sealing groove 182 is too narrow and is not conducive to processing and forming. When the groove width size Bi > 20 mm, the front sealing groove 182 is too wide, and the front sealing member 191 cannot tightly fill the groove, and during the operation of the dishwasher 1, the front sealing member 191 is easy to shake and shift in the front sealing groove 182, resulting in failure of the front sealing member 191.

[0084] Further, the first width bi is not less than 4 mm and not greater than 25 mm. In this way, the front sealing member 191 can effectively fill the front sealing groove 182, and avoid excessive extrusion and deformation of the front sealing member 191, guarantee the sealing effect and block the water leakage. At the same time, it also avoids the excessive waste of the material of the front sealing member 191. When the first width bi < 4 mm, the front sealing member 191 is too narrow, and when facing the narrowest groove width size Bi of 3 mm, it may not be able to completely fill the front sealing groove 182, and the sealing effect is greatly reduced, and water leakage is easy to occur during the washing process, affecting the normal use of the dishwasher 1 and reducing the performance of the dishwasher 1. When the first width bi > 25 mm, the front sealing member 191 is too wide, and it may be difficult to smoothly put into the widest front sealing groove 182 of 20 mm during installation, and forced installation will cause excessive extrusion and deformation of the front sealing member 191, affecting the sealing performance. Moreover, the front sealing member 191 that is too wide will increase the material cost.

[0085] It should be noted that the above-mentioned front sealing member 191 can also be used for sealing the lower washing cavity 1532, that is, the front sealing member 191 is installed on the inner container 15, and when the door body 103 closes the lower washing cavity 1532, the door body 103 is in interference fit with the front sealing member 191. The door body 103 corresponding to the upper washing cavity 1531 here can be the same door body component, or can be two independent door bodies 103 respectively assembled for the upper washing cavity 1531 and the lower washing cavity 1532.

[0086] As a preferred mode of the present embodiment, please refer to Figure 3 and Figure 6As shown, the second protruding portion 1032 is formed on the door body 103 and protrudes towards the washing inner cavity 153, and is located below the first protruding portion 1031 and abuts against the side wall of the partition 16. In this way, a support point is added between the door body 103 and the partition 16, so that the connection between the two is more stable, and the door body 103 can be effectively prevented from shaking or shifting during opening and closing or under the action of external force, thereby improving the stability of the entire structure. At the same time, the structural strength of the door body 103 is also enhanced. In addition, the abutment of the second protruding portion 1032 and the partition 16 can also prevent water from leaking from the gap between the door body 103 and the partition 16 to a certain extent, thereby playing a secondary sealing role and improving the overall sealing performance.

[0087] Further, please refer to Figure 3 , the side wall of the partition 16 is provided with a waterproof gap 166, which is located on the side close to the lower washing cavity 1532, and the shape of the waterproof gap 166 is matched with that of the second protruding portion 1032, and the second protruding portion 1032 is buckled in the waterproof gap 166. On the one hand, the waterproof gap 166 and the second protruding portion 1032 are buckled, which can form a more airtight waterproof structure between the door body 103 and the partition 16, effectively block the possibility of water flowing from the connection between the door body 103 and the partition 16 into other areas, and improve the waterproof performance of the dishwasher 1. On the other hand, it plays a role in precise positioning during installation, which can ensure the accurate installation of the door body 103 and the partition 16, so that the cooperation between the two is more tight and stable, and the structural stability of the entire dishwasher 1 is improved. At the same time, during the operation of the dishwasher 1, the second protruding portion 1032 buckled in the waterproof gap 166 can play a role in buffering and shock absorption to a certain extent, reduce the wear and noise between the door body 103 and the partition 16 due to vibration, collision, etc., and make the operation of the dishwasher 1 more stable and quiet.

[0088] It should be noted that, please refer to Figure 3 and Figure 6As shown, the second protruding portion 1032 is provided with a contact surface 10321 abutting against the partition 16. In the thickness direction G of the partition 16, which is consistent with the groove depth direction Ti, the length dimension Lk of the contact surface 10321 is greater than or equal to 4 mm, so that the second protruding portion 1032 and the partition 16 have a larger contact area, thereby better transmitting force and sharing pressure, enhancing the stability of the connection between the door body 103 and the partition 16, and helping to improve the sealing performance. When Lk < 4 mm, the smaller contact surface 10321 is difficult to make the seal reach a good extrusion state, greatly reducing the sealing effect. At the same time, due to the small contact area, external force is concentrated in a small area, which is easy to cause stress concentration. This will make the contact part of the second protruding portion 1032 and the partition 16 bear excessive pressure, which may cause material deformation, fatigue and even rupture, seriously affecting the structural strength and reliability of the equipment. Preferably, the shape and size of the opening side in the waterproof gap 166 for abutting against the contact surface 10321 are adapted to the shape and size of the contact surface 10321.

[0089] As a preferred mode of the present embodiment, please refer to Figure 3 and Figure 6 As shown, the second protruding portion 1032 is further provided with a first inclined surface 10322 extending from the door body 103 and towards the lower washing cavity 1532 side. In this way, the first inclined surface 10322 can guide the water in the lower washing cavity 1532 to flow along the inclined surface, avoiding the accumulation of water at the connection between the second protruding portion 1032 and the partition 16, reducing the risk of water leakage to other parts, making the drainage more smooth and efficient, and helping to maintain a dry environment inside the equipment. At the same time, the first inclined surface 10322 can also make it difficult for solid foreign matter to stay on the second protruding portion 1032, and more easily slide down along the first inclined surface 10322 under the action of gravity during the operation of the dishwasher 1, thereby reducing the accumulation of foreign matter on the first inclined surface 10322, keeping the inside of the dishwasher 1 clean, and reducing problems such as odor, bacterial growth caused by foreign matter accumulation.

[0090] Further, please refer to Figure 3 and Figure 6As shown, the waterproof gap 166 is provided with a second inclined surface 1661 abutting the first inclined surface 10322, the first inclined surface 10322 forms an angle Φ1 with the horizontal plane, the second inclined surface 1661 forms an angle Φ2 with the horizontal plane, Φ1 is equal to Φ2, which makes the first inclined surface 10322 and the second inclined surface 1661 achieve closer fitting, reducing the gap between them. In terms of waterproofing, such close fitting can effectively prevent water from penetrating from the connection between the second protruding part 1032 and the waterproof gap 166, further improving the overall waterproof performance of the dishwasher 1. At the same time, during the closing process of the door body 103, the contact stress between the first inclined surface 10322 and the second inclined surface 1661 is more uniform, making the connection structure of the door body 103 and the partition 16 more stable.

[0091] It should be noted that the angle range of Φ1 is: 15° < Φ1 ≤ 85°. In this way, not only is it beneficial to guide the water flow to flow quickly along the first inclined surface 10322, but it can also effectively reduce the time the water stays inside the equipment and reduce the risk of water leakage. Of course, it can also prevent solid foreign matter from adhering to the first inclined surface 10322. In addition, it is also beneficial to the processing and molding of the second protruding part 1032. When Φ1 ≤ 15°, since the angle of the first inclined surface 10322 is too small, the first inclined surface 10322 is too flat, and the speed of the water flow flowing down the first inclined surface 10322 will be very slow, which can easily cause water to accumulate near the second protruding part 1032, increasing the risk of water leaking to other parts of the equipment. At the same time, the flat first inclined surface 10322 is not conducive to the sliding of foreign matter, and solid foreign matter is more likely to stay on the first inclined surface 10322, and long-term accumulation can cause bacteria to breed, produce odors, and also affect the performance of the dishwasher 1, increasing the difficulty of cleaning and maintenance. When Φ1 > 85°, the angle of the first inclined surface 10322 is too large, and the first inclined surface 10322 is almost perpendicular to the door body 103, which can easily cause stress concentration when the door body 103 is subjected to external force, causing the second protruding part 1032 to be more prone to cracking, deformation, and other problems. At the same time, the nearly vertical inclined surface can cause the water flow to splash when passing through due to the excessive speed, reducing the waterproof effect, and also possibly impacting the sealing performance of the waterproof gap 166.

[0092] As a preferred mode of the present embodiment, please refer to Figure 4 and Figure 5As shown, the dishwasher 1 further comprises a side seal 192, and the inner tub 15 is provided with a side sealing groove 183, specifically, the inner tub side wall of the inner tub 15 and the partition 16 form the side sealing groove 183, the side sealing groove 183 extends along the up-down direction, and the side seal 192 is embedded in the side sealing groove 183 and is in interference fit with the side sealing groove 183, and part of the side seal 192 protrudes out of the side sealing groove 183 and abuts against the door body 103. In this way, the gap between the inner tub 15 and the door body 103 can be effectively filled, preventing water leakage from the side of the door body during the cleaning process, especially when the dishwasher is working, the internal pressure and water flow impact are large, the side seal 192 can ensure good sealing performance, maintain a stable working environment, and avoid problems such as surrounding environment dampness, dishwasher damage, etc. caused by leakage.

[0093] Further, the side seal 192 comprises a side rubber strip body 1921 and a second drainage portion 1922, the second height of the side rubber strip body 1921 is greater than the side groove depth of the side sealing groove 183, so that after the side seal 192 is installed into the side sealing groove 183, part of the side seal 192 will protrude out of the side sealing groove 183, thereby forming interference fit with the door body 103 and other components, the second drainage portion 1922 extends obliquely from an end of the side rubber strip body 1921 to the door body 103, the end is the end of the second drainage portion 1922 protruding out of the side sealing groove 183 of the side rubber strip body 1921, and the second drainage portion 1922 extends obliquely from the side of the inner tub side wall of the inner tub 15 towards the door body 103, and the second drainage portion 1922 is fixedly connected with the side rubber strip body 1921, and the fixed connection here is preferably integrally formed. In this way, when the dishwasher 1 is working, the water in the washing inner cavity 153 can flow along the second drainage portion 1922 to the designated position, avoiding water accumulation at the side seal 192, ensuring smooth drainage, reducing bacterial growth and odor generation caused by water accumulation, and also reducing the risk of corrosion of the side seal 192 and other components caused by water accumulation.

[0094] Of course, the side rubber strip body 1921 can also be provided with a second extension portion, the second extension portion extends from the side rubber strip body 1921 and is inclined to the center line of the side rubber strip body 1921, and the second extension portion is preferably inclined to one side of the slot opening of the side sealing groove 183. Preferably, the second extension portion is preferably configured as a plurality of second extension portions, and the plurality of second extension portions are uniformly arranged along the center line of the side rubber strip body 1921, each second extension portion abuts against the inner groove wall of the side sealing groove 183, and each second extension portion is integrally formed with the side rubber strip body 1921. This not only facilitates the installation of the side seal 192 into the side sealing groove 183, greatly reducing the alignment difficulty and time during installation, and improving the installation efficiency. At the same time, due to the good elasticity of the second extension portion, even if there is a slight deviation in the size of the side sealing groove 183 during installation, the second extension portion can also be self-adapted and adjusted through its own deformation.
