Description

Technical Field

[0001] The present application belongs to the technical field of dishwashers, and in particular to a dishwasher with an under-door sealing structure. Background Art

[0002] A common dishwasher is generally equipped with a bowl basket. When the dishwasher door is closed, the front end of the bowl basket is very close to the inner door panel of the dishwasher, which is easy to cause interference and even affect the sealing of the door. Therefore, an avoidance groove corresponding to the position of the bowl basket is generally provided on the inner door panel of the dishwasher door, and the avoidance arrangement of the avoidance groove and the front end of the bowl basket is used to solve the mutual interference problem between the dishwasher door and the bowl basket.

[0003] However, the avoidance groove on the inner door panel forms a triangular pocket structure near the lower end of the door, and the residues in the cleaning process are easily gathered on the pocket structure. As the dishwasher door is opened and closed, especially in the process of closing the door, the residues on the above part are easily poured into the inner tank and directly reach the front part of the bottom plate of the inner tank, that is, the lower end of the door is located on the inner tank, which is inaccessible to human hands and difficult to clean.

[0004] In addition, a sealing structure is generally provided under the door of the dishwasher, and the sealing structure includes at least a sealing strip at the lower end of the dishwasher door body, and the sealing strip is used to seal the movement gap between the lower end of the door body and the inner tank. In combination with the above technical problems, the sealing strip will also block the above-mentioned residue flowing into the inner tank from the inner cavity of the inner tank. Therefore, it is impossible to use the cleaning water in the inner tank to clean the residue.

[0005] It can be seen that with the sealing structure under the dishwasher door in the prior art, the residue on the door body will flow into the inner tank as the door is closed, but this part of the remaining residue will be blocked outside the inner cavity of the inner tank by the sealing strip under the door and cannot be cleaned, which is prone to produce odor and affects actual use. Summary of the invention

[0006] The purpose of the embodiments of the present application is to provide a dishwasher to solve the technical problem that the residue flowing from the door to the inner pot in the prior art dishwasher is easily retained outside the inner cavity of the inner pot, resulting in the inability to clean and affecting the use.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is to provide a sealing structure under a dishwasher door, comprising:

[0008] A door body, wherein a sealing strip is provided at the lower end of the door body, and a scraper extending outward is provided on the sealing strip;

[0009] The inner pot comprises a bottom plate, the front end of the bottom plate has a rib, the rib has a first step for sealing with the sealing strip, the height of the first step is set to be higher than the liquid level of the washing water; the lower end of the door body also includes a pouring part for residual residue, when the closing angle of the door body is between 30 and 90 degrees, the lower end of the door body is blocked by the first step, and the projection of the pouring part on the bottom plate is located in an area below the height of the first step;

[0010] Wherein, the sealing strip is arranged to make the scraper adhere to the retaining edge and move toward the first step as the door body closes, until it rests on the first step.

[0011] In this way, the sealing strip can maintain its sealing effect and prevent the residue poured from the door body from being blocked outside the inner cavity of the inner tank, making it convenient to use the cleaning water in the inner tank to flush the residue in this area, effectively solving the problem that the residue remaining in the sealing structure under the door of a traditional dishwasher cannot be removed.

[0012] The structure on the chassis retaining edge is improved, and the connection between the upper surface of the first step and the retaining edge is bent and formed to form a reset groove for the scraper to stretch and recover. The reset groove allows the scraper to elastically stretch and recover during the movement, which is beneficial to reduce the friction strength between the scraper and the retaining edge surface, thereby reducing the force applied when opening and closing the door, effectively eliminating the sound that is easily generated when opening and closing the door, and improving the noise reduction effect.

[0013] The structure of the sealing strip is improved, and the sealing strip also includes a fixing portion for fixing to the lower end of the door body, and the scraper is integrally connected to the fixing portion and extends outward after being bent from the fixing portion. In this way, the cross-sectional shape of the sealing strip forms a structure similar to a "7" shape, and the sealing strip is conveniently fixed to the lower end of the door body by using this structure.

[0014] The entire lower door sealing structure is improved, and the dishwasher further includes a blocking piece arranged at the lower corner of the door body. During the closing process of the door body, the lower end of the door body is embedded in the blocking piece; the blocking piece raises the door body so that the lower end of the door body is separated from the bottom surface of the chassis to form a flow gap, and the flow gap is located in the area below the height of the first step. The cleaning water in the inner cavity of the inner tank can pass through the flow gap to reach the area below the height of the first step, thereby washing away the residue poured from the door body.

[0015] In one embodiment, the blocking member has a second step for being spliced ​​with the first step, and the lower end of the door body is provided with a hook for fixing the sealing strip; the sealing strip is fixed on the hook, and when the door is closed, at least part of the scraper can be placed on the first step and the second step at the same time, effectively ensuring the sealing effect of the gap between the lower corner of the dishwasher door and the lower corner of the inner tank opening.

[0016] In one embodiment, the blocking member further includes a retaining wall disposed adjacent to the second step, and an elastic water retaining rib is disposed on the retaining wall. The water retaining rib can be used to prevent water from splashing out of the dishwasher from the gap between the lower end of the door body and the blocking member, thereby solving the problem of water leakage in the dishwasher. At the same time, the water retaining rib is elastically disposed, so that when the door is closed, the lower end of the door body can resist the water retaining rib, causing the water retaining rib to deform, which is conducive to offsetting the dimensional deviation of the lower end of the door body.

[0017] In one embodiment, a hollow groove is provided below the second step; the water retaining rib is connected to the second step, and a backflow groove is formed on the retaining wall within the surrounding range of the water retaining rib, and the backflow groove is connected to the hollow groove to form a water storage tank in the blocking member. The water storage tank can confine water in the blocking member to prevent water from overflowing and leaking out of the dishwasher.

[0018] In one embodiment, the blocking member is further provided with a vent hole communicating with the outside and a vent groove at the bottom of the blocking member, and the vent groove is communicated with the vent hole. The gas in the inner cavity of the inner tank is discharged to the outside of the dishwasher through the vent groove and the vent hole on the blocking member, so that the air pressure in the inner tank is balanced with the outside of the dishwasher, thereby achieving a pressure relief effect.

[0019] In one embodiment, the front end of the blocking member has a positioning sleeve, which is used to be fixed on the retaining edge of the chassis; the positioning sleeve is also provided with a clamping block protruding outward, which is used to be clamped with a fixing component on the inner tank of the dishwasher to fix the blocking member from the front and rear directions, thereby ensuring the fixing effect of the blocking member.

[0020] In one embodiment, the side of the blocking member has a rim for covering the lower corner of the door body, and the rim has a buckle block for fixing to the door frame of the dishwasher. The buckle block is buckled with the buckle hole to fix the blocking member from the left and right directions, thereby improving the fixing effect of the blocking member.

[0021] The dishwasher and the sealing structure under the door provided by the present application have the following beneficial effects: compared with the prior art, the sealing structure under the door body of the dishwasher of the present application is improved. On the one hand, a first step is provided on the front end retaining edge of the chassis of the inner tank, and the positional relationship between the first step and the residue pouring part on the door body is set. When the closing angle of the door body is between 30 and 90 degrees, the lower end of the door body is shielded on the first step, and the vertical projection of the pouring part on the door body on the chassis is located in an area below the height of the first step. In this way, the residue poured from the door body into the inner tank can fall into the area below the height of the first step, making it convenient to use the cleaning water in the inner tank to rinse the residue.

[0022] On the other hand, the structure of the sealing strip has been redesigned. The sealing strip has a scraper blade extending outward. As the door body closes, the elastic scraper blade can deform and keep pressing against the retaining edge of the inner tank chassis until the door body is completely closed, and the scraper blade rests on the first step, thereby maintaining the sealing effect. Since the scraper blade rests on the first step, the residue poured from the door body will fall into the area below the height of the first step, so the residue can be within the range that can be washed by the cleaning water of the inner tank, so that the cleaning water in the inner tank can be used to wash the residue in this area, effectively solving the problem that the residue remaining in the sealing structure under the door cannot be removed, ensuring the cleanliness of the whole machine, and thus improving the user experience of consumers.

[0049] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0051] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0052] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0053] like Figure 1As shown, the inner door panels of dishwashers on the market generally have an avoidance groove X. After the door is closed, the avoidance groove X on the inner door panel is arranged to avoid the front end of the bowl basket. The part of the avoidance groove X near the lower end of the door forms a triangular pocket structure Y, which easily accumulates the residue left during the cleaning process. When the residue accumulates in this part, when the door is closed again, the residue will pour toward the inner tank as the door is closed, and then accumulate on the front part of the inner tank chassis. Because they are all in the gaps, they cannot be reached by hand and are therefore difficult to clean. If you want to clean it, you can only disassemble the machine and remove the obstructing parts for cleaning. Consumers cannot deal with it directly, and can only let it dry naturally, but it is easy to produce odor, affecting the user experience.

[0054] In addition, combined with the sealing structure at the lower end of the door body, a sealing strip is generally provided at the lower end of the door body of the dishwasher, and the sealing strip is used to seal the movement gap between the lower end of the door body and the inner tank. Figure 2 As shown, the sealing strip Z will also block the residue P accumulated on the front end of the inner tank chassis from the inner cavity of the inner tank. Therefore, it is impossible to use the cleaning water in the inner tank to clean the residue, which is a headache for manufacturers.

[0055] It can be seen that the above technical problems are easily overlooked by the inertial production thinking in the industry, but they are technical defects that do exist. In the conventional structure of the dishwasher, it is unexpected that the groove designed to avoid the bowl basket on the inner door panel has become a place where residues are easily collected, and these residues will also pour into the inner tank when the door is closed; it is also unexpected that the sealing strip for sealing the lower part of the door has become a barrier that prevents these residues from entering the range that can be washed by the inner tank cleaning liquid, thus causing the residues in the narrow space under the door to be unable to be removed. In actual applications, these residues can be very small and difficult to detect in normal use, but with long-term use, they gradually accumulate and increase. At the same time, these residues will also produce odors, which have a great impact on actual use, and even become customer complaints, affecting the brand image.

[0056] Here, the inventor has learned and discovered the above technical problems through a large number of tests and combined with user feedback, and found that this technical problem is already creative, and sought a solution. The embodiment of the present application provides a new type of dishwasher, which can clean the residue poured from the door body while ensuring the sealing under the door, and effectively solves the technical problem that the residue flowing from the door body to the inner tank in the traditional dishwasher is easily left outside the inner cavity of the inner tank, resulting in inability to clean, affecting actual use. It is now described in detail.

[0057] Please also read Figure 3 , Figure 4 and Figure 5The dishwasher comprises an inner container 1 and a door body 2. The inner container 1 has an opening 10 on the front side, and the bowl basket can be loaded into the inner container 1 through the opening 10. The door body 2 is arranged on the front side opening 10 of the inner container 1, and can be spread out on the front side opening 10 of the inner container 1, so as to form a sliding platform for the bowl basket to slide into the inner container 1. In this state, the tableware residue on the bowl basket can directly fall onto the spread door body 2 and remain in the above-mentioned avoidance groove.

[0058] When closing the door, the door body 2 rotates toward the opening 10 of the inner pot 1 until it is completely closed on the front opening 10 of the inner pot 1. It can be seen that during the closing process, the door body 2 will be tilted toward the inner pot 1. At this time, the residue accumulated on the door body 2 will gradually pour into the inner pot 1 as the closing angle of the door body 2 changes.

[0059] Among them, Figure 4 and Figure 5 As shown, the closing angle of the door body 2 can be understood as the angle a between the horizontal plane on which the dishwasher is placed and the door body 2. When the closing angle a is 0 degrees, the door body 2 is in a completely flat state; when the closing angle a is 90 degrees, the door body 2 is in a completely closed (vertical) state on the inner tank 1; when the closing angle a is between 0 degrees and 90 degrees, the door body 2 is in a state of tilting toward the inner tank 1.

[0060] See also Figure 6 The door body 2 includes an inner door panel 21, and a sealing strip 3 is provided at the lower end of the inner door panel 21. The sealing strip 3 is used to seal the movement gap between the lower end of the door body 2 and the inner liner 1 as the door body 2 moves to close.

[0061] Please also read Figure 7 , Figure 8 and Fig. 9 A bottom plate 11 is provided at the bottom of the inner liner 1, and a rib 12 is provided at the front end of the bottom plate 11. The rib 12 has a first step 13 for sealing with the sealing strip 3. The rib 12 and the first step 13 on the front end of the bottom plate 11 are both located below the front opening 10 of the inner liner 1.

[0062] Please also refer to Fig. 9 , Fig.10 and Fig.11 The height of the first step 13 is set to be higher than the liquid level of the cleaning water. It can be understood here that the water level in the inner tank 1 can reach the area M below the first step 13, and this area M can be washed by the cleaning water in the inner tank 1.

[0063] The lower end of the inner door panel 21 of the door body 2 further includes a pouring portion 22 for residual residue, that is, when the door body 2 is tilted, the residual residue on the inner door panel 21 flows out from the pouring portion 22. The pouring portion 22 may be the bottom edge of the inner door panel 21, or may be a flow outlet specially provided on the bottom edge of the inner door panel 21, etc., which is not specifically limited here.

[0064] like Fig. 9 As shown, the positional relationship between the first step 13 and the pouring portion 22 of the door body 2 is set as follows: when the closing angle a of the door body 2 is between 30 degrees and 90 degrees, the lower end of the door body 2 is blocked on the first step 13, and the vertical projection of the pouring portion 22 on the chassis 11 is located in the area M below the height of the above-mentioned first step 13, so that the cleaning water in the inner tank 1 can rinse away the poured residue.

[0065] Please also read Fig. 9 and Fig.11 The sealing strip 3 is preferably an elastic member, and can be preferably made of elastic plastic, and has a scraper 31 extending outward. Since the entire sealing strip 3 is elastic, the scraper 31 extending outward on the sealing strip 3 can be pressed against the action member to deform.

[0066] In this embodiment, the sealing strip 3 is configured to make the scraper 31 fit on the retaining edge 12 as the door body 2 closes, and move toward the first step 13 until it rests on the first step 13. Fig. 9 As shown, during the closing process of the door body 2, the scraper 31 on the sealing strip 3 remains pressed against the retaining edge 12, and can be deformed as the contacting portion with the surface of the retaining edge 12 changes, but still remains in close contact with the retaining edge 12; and, after the door body 2 is completely closed, as shown in FIG. Fig.11 As shown, the scraper 31 is placed on the first step 13. In this way, the sealing effect of the bottom of the dishwasher door is ensured, and the residue poured from the door body 2 is kept below the height of the first step 13, so as to avoid blocking the residue outside the range of the washing water of the inner tank 1, and ensure that the residue can be naturally washed away by the washing water in the inner tank 1.

[0067] Compared with the prior art, the dishwasher provided in the embodiment of the present application improves the sealing structure under the door body 2. First, a first step 13 is provided on the front end rib 12 of the chassis 11 of the inner tank 1, and the positional relationship between the first step 13 and the residue pouring part 22 on the door body 2 is set. When the closing angle a of the door body 2 is between 30 and 90 degrees, the lower end of the door body 2 is blocked on the first step 13, and the vertical projection of the pouring part 22 on the door body 2 on the chassis 11 is located in the area M below the height of the first step 13. In this way, the residue poured from the door body 2 into the inner tank 1 can fall below the height of the first step 13, so that the residue can be easily washed with the cleaning water in the inner tank 1.

[0068] Secondly, the structure of the sealing strip 3 is redesigned. The sealing strip 3 has a scraper 31 extending outward. As the door body 2 closes, the elastic scraper 31 can be deformed and keep pressing against the retaining edge 12 of the bottom plate 11 of the inner tank 1, and when the door body 2 is completely closed, the scraper 31 rests on the first step 13, thereby maintaining the sealing effect. Since the scraper 31 rests on the first step 13, the residue poured from the door body 2 will fall into the area M below the height of the first step 13, so that the residue can be within the range that can be washed by the cleaning water of the inner tank 1, so that the residue in this area can be washed by the cleaning water in the inner tank 1, which effectively solves the problem that the residue remaining in the sealing structure under the door cannot be removed, ensures the cleanliness of the whole machine, and thus improves the user experience of consumers.

[0069] For the specific structure of the sealing strip 3, in one embodiment of the present application, please refer to Figure 6 and Fig.12 The sealing strip 3 further includes a fixing portion 32 for fixing to the lower end of the door body 2, and the fixing portion 32 is used to be inserted into the portion of the door body 2 for installing the sealing strip 3. In this embodiment, the portion of the door body 2 for fixing the sealing strip 3 is preferably a hook 23 provided on the lower end of the door panel 21 inside the door body 2, and the fixing portion 32 of the sealing strip 3 can be fastened and fixed to the hook 23.

[0070] The scraper 31 on the sealing strip 3 is integrally connected to the fixing portion 32 on the sealing strip 3, and is bent from the fixing portion 32 and extends outward. Fig.12 As shown, the scraper blade 31 and the fixing portion 32 are bent, and the angle between the scraper blade 31 and the fixing portion 32 after bending is preferably an acute angle, so that the cross-sectional shape of the sealing strip 3 forms a structure similar to a "7" shape, and using the 7-shaped structure, the sealing strip 3 can be buckled and fixed on the hook 23 of the door body 2.

[0071] Among them, Fig.12As shown, according to the fixing requirements, damping patterns 33 may be preferably provided on the scraper 31 and / or the fixing portion 32 to increase the friction effect with the contact parts such as the surface of the hook 23 or the working parts that the scraper 31 needs to press against, thereby playing a damping role and improving the fixing effect and the sealing effect.

[0072] In actual application, since the scraper 31 on the sealing strip 3 of the present application is extended outward and has a large extension range, as the door body 2 is opened and closed, the scraper 31 will deform according to the surface contact strength with the sidewall 12 of the chassis 11, and keep moving against the sidewall 12 of the chassis 11. In this process, a large damping force will be generated, which is easy to affect the opening and closing operation of the door body 2, making the opening and closing operation difficult, and consumers need to apply a large force to complete the opening and closing operation. In addition, the plastic material of the scraper 31 and the plate material of the sidewall 12 of the chassis 11 are hard rubbed, which is also easy to make a loud noise, resulting in friction noise every time the opening and closing operation is performed, affecting the user experience.

[0073] Here, the structure of the retaining edge 12 on the chassis 11 is optimized. In one embodiment of the present application, please refer to Fig. 9 and Fig.11 The connection between the upper surface of the first step 13 and the retaining edge 12 is bent and formed to form a reset groove 14 for the scraper 31 to stretch and recover. The reset groove 14 allows the scraper 31 to elastically stretch and recover during the movement, which is beneficial to reducing the friction strength between the scraper 31 and the retaining edge 12 surface.

[0074] On the one hand, it reduces the damping force of the mutual friction between the two, which helps to reduce the force applied in door opening and closing operations, allowing consumers to easily open and close the door.

[0075] On the other hand, the noise easily made when opening and closing the door is eliminated, and the noise problem caused by the hard friction between the scraper 31 and the surface of the retaining edge 12 when opening and closing the door is effectively solved, which has a noise reduction effect and improves the user experience.

[0076] For the gaps between the lower corners of the dishwasher door 2 and the lower corners of the inner tank 1 opening 10, the entire dishwasher door lower sealing structure is optimized. In one embodiment of the present application, please refer to Fig.13 , Fig.14 and Fig.15 The dishwasher further comprises a blocking member 4 arranged at a corner of a lower end of the door body 2 , and during the closing process of the door body 2 , the lower end of the door body 2 is embedded in the blocking member 4 .

[0077] In this embodiment, if Fig.14As shown, the blocking member 4 includes a base 41 and a rim 42 on one side of the base 41, and the blocking member 4 is used to fill the gap between the lower corner of the door body 2 and the lower corner of the front opening 10 of the inner container 1. An embedded part 43 is provided on the base 41 of the blocking member 4, and the lower end of the door body 2 is embedded in the embedded part 43 of the base 41 as the door is closed.

[0078] It can be seen that Fig.15 As shown, the door body 2 is raised by using the blocking member 4 so that the lower end of the door body 2 is spaced from the bottom surface of the chassis 11 to form a flow gap N, which is located in the area M below the height of the first step 13 .

[0079] In this way, the cleaning water in the inner cavity of the inner tank 1 can pass through the above-mentioned flow gap N to reach the area M below the height of the first step 13, thereby washing away the residue poured from the door body 2, effectively solving the problem that the poured residue is difficult to clean.

[0080] In one embodiment of the present application, please refer to Fig.14 and Fig.15 The blocking member 4 has a second step 44, which is used to be spliced ​​with the first step 13 on the rib 12 of the chassis 11. In this embodiment, when the blocking member 4 is installed in place, the second step 44 on the blocking member 4 is horizontally spliced ​​with the first step 13 on the rib 12 of the chassis 11, so that the upper surface of the first step 13 is flush with the upper surface of the second step 44.

[0081] The lower end of the inner door panel 21 of the dishwasher door body 2 is provided with a hook 23 for fixing the sealing strip 3. The sealing strip 3 is fixed on the hook 23. When the door is closed, at least part of the scraper 31 can be placed on the first step 13 and the second step 44 at the same time. Since the sealing strip 3 is arranged on the lower end of the door body 2, the length of the sealing strip 3 is similar to the length of the lower side of the door body 2. In the process of closing the door, the two corners of the lower end of the door body 2 are gradually inserted into the blocking member 4, and the scraper 31 parts of the two ends of the sealing strip 3 arranged at the lower end of the door body 2 near the corners will be placed on the first step 13 and the second step 44 at the same time, thereby ensuring the sealing effect of the gap between the lower corner of the door and the lower corner of the opening 10 of the inner tank 1.

[0082] In this embodiment, if Fig.14 and Fig.15As shown, a second step 44 is provided at the front end of the base 41 of the blocking member 4, and a limiting vertical plate 45 is provided at the rear end of the base 41. An embedded portion 43 for the lower end of the door body 2 to be embedded is provided between the limiting vertical plate 45 and the second step 44. When the door body 2 is closed, the lower end of the door body 2 will be embedded in the embedded portion 43. Since the embedded portion 43 of the blocking member 4 is located below the second step 44, the residue poured from the door will also fall into the embedded portion 43 of the blocking member 4. At this time, the residue on the embedded portion 43 can be rinsed clean with the cleaning water in the inner tank 1, effectively ensuring the cleanliness of the lower corner of the dishwasher door.

[0083] In actual application, a movable gap must be reserved between the lower corner of the door and the lower corner of the opening 10 of the inner tank 1 so that the door body 2 can be opened and closed smoothly. However, the cleaning water in the inner tank 1 of the dishwasher can easily splash out of the dishwasher from this gap, causing water leakage in the dishwasher.

[0084] Here, the specific structure of the blocking member 4 is further optimized. In one embodiment of the present application, please refer to Fig.16 The blocking member 4 further includes a retaining wall 46 disposed adjacent to the second step 44 , and an elastic water retaining rib 461 is disposed on the side of the retaining wall 46 .

[0085] On the one hand, the water retaining rib 461 can prevent water from splashing out of the dishwasher from the gap between the lower end of the door body 2 and the blocking member 4, thereby effectively solving the problem of water leakage in the dishwasher.

[0086] On the other hand, the water retaining rib 461 is elastically arranged, which is helpful to offset the size deviation on the lower end of the door body 2. For example, the sealing strip 3 arranged on the buckle 23 of the door body 2, the bulging part caused by the sealing strip 3 protruding to the left and right, can directly stop on the water retaining rib 461 during the door closing process, so that the water retaining rib 461 is elastically deformed, thereby offsetting the size deviation, so that the door body 2 can be closed smoothly.

[0087] In other embodiments, the entire blocking member 4 may be made of an elastic material such as soft plastic, so that the entire blocking member 4 and its water retaining rib 461 are elastic structures, which facilitates the correction deformation against the lower end of the door body 2 when closing the door, effectively improving the correction effect of the dimensional deviation, and thereby improving the compatibility of the blocking member 4.

[0088] Based on the above, in another embodiment of the present application, please refer to Fig.16 The second step 44 has a hollow groove 441 below. The water retaining rib 461 is connected to the upper surface of the second step 44. The water retaining rib 461 forms a backflow groove 462 on the retaining wall 46 within the surrounding range on the retaining wall 46. The backflow groove 462 is connected to the hollow groove 441 to form a water storage tank in the embedded part 43 of the blocking member 4.

[0089] The cleaning water in the inner tank 1 of the dishwasher will be flushed to the above-mentioned water storage tank. The water storage tank formed by the backflow groove 462 and the hollow groove 441 can limit the water in the sealing member 4, effectively preventing the water from overflowing and leaking out of the dishwasher.

[0090] In actual application, due to the sealing structure under the door of the dishwasher, the dishwasher will use heating or warm water to clean the dishes during operation, resulting in an increase in the internal pressure of the inner tank 1. The water level in the inner tank 1 will rise due to the internal pressure. When combined with this solution, the increase in the water level in the inner tank 1 will simultaneously affect the area M below the height of the first step 13. If the water level is too high, it will cause the water to overflow.

[0091] Here, the structure of the blocking member 4 is further optimized. In one embodiment of the present application, please refer to Fig.15 and Fig.16 The blocking member 4 is also provided with a venting groove 47 and a venting hole 48, and the venting hole 48 is communicated with the outside world, such as the outside of the dishwasher. The venting groove 47 is opened at the bottom of the blocking member 4, and the venting groove 47 is communicated with the venting hole 48.

[0092] In this embodiment, a concave groove structure is provided at the bottom of the base 41 of the sealing member 4, thereby forming a ventilation groove 47 on the water level. When the scraper 31 on the sealing strip 3 is placed on the first step 13, the gas inside the scraper 31 can be discharged from the outside of the dishwasher through the ventilation groove 47 and the air hole 48.

[0093] The air holes 48 on the blocking member 4 can be arranged on the side edge 42, or other parts of the blocking member 4 where holes can be opened. The number and arrangement positions of the air holes 48 can be determined according to the structure of the blocking member 4. The air holes 48 can be directly connected to the ventilation grooves 47, or can be connected to each other through a guide structure arranged in the middle. The specific form of the air holes 48 is not specifically limited here.

[0094] In this way, the gas in the inner cavity of the inner tank 1 is discharged to the outside of the dishwasher through the ventilation grooves 47 and the air holes 48 on the sealing member 4 in turn, so that the air pressure in the inner tank 1 is balanced with the outside of the dishwasher, thereby playing a pressure relief role and effectively controlling the water level height on the bottom plate 11 of the inner tank 1 to avoid leakage of the dishwasher caused by excessive water level.

[0095] For the installation structure of the blocking member 4, in one embodiment of the present application, please refer to Fig.15 and Fig.16 The front end of the blocking member 4 has a positioning sleeve 49, and the positioning sleeve 49 is used to be fixed on the rib 12 of the chassis 11. Specifically, the front end of the blocking member 4 can be fixed on the end of the rib 12 of the chassis 11 by the positioning sleeve 49.

[0096] Please also refer to Fig.16 , Fig.17 and Fig.18 The positioning sleeve 49 is also provided with a block 491 protruding outward, and the block 491 is used to engage with the fixing component on the inner tank 1 of the dishwasher. The fixing component on the inner tank 1 of the dishwasher can be the front fixing plate 15 on the bottom plate 11 of the inner tank 1. In this embodiment, Fig.18 As shown, the block 491 on the positioning sleeve 49 can be engaged with the front fixing plate 15 to fix the blocking member 4 from the front-to-back direction, thereby ensuring the fixing effect of the blocking member 4.

[0097] In another embodiment of the present application, please refer to Fig.16 , Fig.17 and Fig.18 The side of the blocking member 4 has a rim 42 for covering the lower corner of the door body 2, and the rim 42 has a buckle block 421 for fixing on the dishwasher door frame 16.

[0098] In this embodiment, if Fig.18 As shown, a buckle hole 161 is provided on the door frame 16 of the dishwasher, and the buckle hole 161 corresponds to the buckle block 421 on the blocking member 4. The buckle block 421 is buckled with the buckle hole 161 to fix the blocking member 4 from the left and right directions, thereby improving the fixing effect of the blocking member 4.

[0099] It can be seen that since the blocking member 4 is generally made of soft plastic, it is convenient for the lower end of the door body 2 to be squeezed and deformed when there is a dimensional deviation, so as to correct the dimensional deviation and achieve smooth closing of the door. Therefore, the blocking member 4 is easily squeezed and displaced in actual application. Here, in order to improve the fixing effect of the blocking member 4, the positioning sleeve 49 and the clamping block 491 on the positioning sleeve 49 are arranged at the front end of the blocking member 4 to fix the front and rear directions of the blocking member 4. At the same time, a buckle block 421 is arranged on the edge 42 of the blocking member 4, so that the buckle block 421 is buckled and fixed with the buckle hole 161 on the door frame 16, so as to fix the blocking member 4 from the left and right directions. In this way, the fixing structures at the above two places are utilized to prevent the blocking member 4 from being easily squeezed and displaced in actual application, and effectively improve the fixing effect of the blocking member 4.

[0100] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
