Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning machines, in particular to a cleaning machine with a sealing structure. BACKGROUND

[0002] In existing kitchen appliances, such as steam ovens, steam ovens, cleaning machines, etc., all include a box body with a functional inner cavity and a door body provided at the opening of the box body to open or close the opening. The structure of the cleaning machine includes a door body and an inner tank forming a washing space, and a washing mechanism is arranged in the washing space. In order to ensure that the washing water does not leak from the gap between the tank body and the door body during washing, a sealing structure is provided between the periphery of the door body and the inner tank.

[0003] For a top-opening cleaning machine (i.e., the door body covers the top opening of the inner tank), some current solutions are to provide an integrally formed annular sealing ring on the door body, as shown in the Chinese invention patent No. CN202122957229.2 (publication No. CN216417111U) “Sealing structure of sink type dishwasher door”.

[0004] However, for a side-opening cleaning machine (i.e., the door body is rotatably arranged at the side opening of the inner tank), the inner door is located in the inner tank, the upper part of the inner door can swing forward and backward, and the inner door side wall has an avoidance opening adjacent to the bottom part thereof to avoid the inner tank during rotation, resulting in that the side wall and the bottom wall of the inner door are not completely connected, i.e., there is no annular structure on the inner door to fit the integrally formed annular sealing ring. If the integrally formed annular sealing ring is arranged in the inner tank, a frame that can form a containing groove (for containing the sealing ring) with the bottom wall surface of the inner tank needs to be riveted on the bottom wall surface of the inner tank, and the bottom wall surface of the inner tank is usually not a flat surface, so riveting the frame will be difficult.

[0005] Therefore, the current embedded dishwasher door sealing basically adopts left, right and upper three edge sealing strips installed on the inner tank assembly to form end face sealing with the inner door, as disclosed in the Chinese invention patent No. CN201520328405.8 (publication No. CN204850983U) “Dishwasher door sealing structure and dishwasher comprising the same”. The door sealing structure includes a sealing strip, and the sealing strip includes an upper sealing strip, a left sealing strip and a right sealing strip, and the upper sealing strip, the left sealing strip and the right sealing strip are welded into one body.

[0006] The bottom sealing strip is arranged on the door body, such as the Chinese patent application for invention with the patent number CN200920050045.4 (the publication number CN201346193Y) discloses a door bottom water blocking sealing strip for a dishwasher, the sealing strip comprises a body clamped on the inner door and a first sealing soft foot and a second sealing soft foot for sealing the bottom disc of the inner container, wherein the included angle θ between the first sealing soft foot and the second sealing soft foot is 90°≤θ≤180°, the first sealing soft foot is arranged at the bottom of the bottom disc of the inner container, and the second sealing soft foot is arranged at the side of the bottom disc of the inner container. In the application, the included angle θ between the two sealing soft feet of the sealing strip is 90°≤θ≤180°, the first sealing soft foot is arranged at the bottom of the bottom disc of the inner container, and the second sealing soft foot is arranged at the side of the bottom disc of the inner container, when the inner door is closed, the two sealing soft feet are pressed against the inner wall of the bottom disc of the inner container at the same time, and the sealing is tighter under the impact of water flow.

[0007] At present, the corners of the left and right sealing strips and the bottom sealing strip are not sealed, that is, the upper, left, right and bottom sealing strips do not form a closed ring in the closed state of the door body, and there are sealing dead angles at the left and right corners of the inner container. When cleaning, water will enter the area outside the bottom sealing strip of the inner container from the left and right sealing dead angles, and if the water flow is strong, there is a risk of overflow from the cleaning machine.

[0008] In addition, the door body of the dishwasher is generally composed of an inner door body and an outer door body (as shown in the above patent), and the two door bodies are connected to form a whole, but there is a gap between the inner door body and the outer door body. If the sealing between the inner container and the door body is not good, a large amount of water vapor will enter between the inner and outer doors when the cleaning machine is cleaning, damaging the electrical components installed in the door body, and water will also flow out from the gap between the inner and outer doors and drop onto the table top. SUMMARY

[0009] The technical problem to be solved by the present application is to provide a cleaning machine with a sealing structure capable of sealing the sealing dead angle between the side sealing strip and the bottom sealing strip in view of the current status of the prior art.

[0010] The technical scheme adopted by the present application to solve the above technical problem is as follows: a cleaning machine with a sealing structure, comprising an inner container, a front side being open;

[0011] a door body rotatably arranged at the front side of the inner container, in the closed state of the door body, the door body is at least partially embedded in the inner container, thereby opening or closing the opening of the inner container;

[0012] The sealing structure comprises two vertically extending side sealing strips arranged left and right, a top sealing strip extending left and right arranged above the two side sealing strips, and a bottom sealing strip extending left and right arranged below the two side sealing strips, and in the closed state of the door body, the sealing structure is located between the inner container and the door body to form a seal between the inner container and the door body, wherein the top sealing strip and the two side sealing strips are installed in the inner container and arranged adjacent to the opening of the inner container, the top sealing strip is arranged at the top wall of the inner container, and the two side sealing strips are respectively arranged at the left and right side walls of the inner container.

[0013] The bottom sealing strip is installed at the bottom of the door body, and the end of the bottom sealing strip is spaced apart from the lower end of the corresponding side sealing strip, and a sealing segment is arranged between each side sealing strip and the bottom sealing strip, and in the closed state of the door body, the sealing segment is pressed against the bottom wall surface of the inner container, one end of the sealing segment is connected to or abuts against the corresponding side sealing strip, and the other end of the sealing segment is connected to or abuts against the bottom sealing strip.

[0014] In order to facilitate the formation of the sealing segment, the lower end of the side sealing strip is transversely bent to extend to form the sealing segment, and the free end of the sealing segment abuts against the bottom sealing strip. In this way, as long as the length of the side sealing strip is made longer, the side sealing strip is locally bent to form the sealing segment during installation.

[0015] In order to further prevent water leakage between the inner container and the door body, the two ends of the bottom sealing strip abut against the wall surface of the corresponding side of the inner container to form a seal, so that even if the sealing segment leaks at the intersection with the side sealing strip and the bottom sealing strip, the cooperation between the two ends of the bottom sealing strip and the inner container forms a second barrier to prevent water leakage.

[0016] In order to facilitate the arrangement of the bottom sealing strip, the door body comprises an outer door and an inner door connected together, the bottom of the inner door is located in the inner container, the upper part of the inner door can be deflected forward and backward relative to the inner container, and the bottom sealing strip is installed at the bottom of the inner door. In this way, the door body is designed as an inner door and an outer door, and the bottom sealing strip is arranged on the inner door, so that the bottom sealing strip does not protrude when the door body is closed, and the appearance of the washing machine is good.

[0017] In order to prevent the sealing segment from being displaced vertically and affecting the pressing firmness of the sealing segment against the bottom sealing strip, thereby affecting the sealing effect, a positioning block is fixedly arranged in the inner container, the positioning block is pressed against the upper surface of the sealing segment, and the positioning block serves to position the sealing segment, thereby forming a stable and reliable corner seal.

[0018] In order to guide the sealing section, the bottom of the positioning block is provided with a guide groove for the sealing section to pass through, one end of the guide groove is towards the lower end of the side sealing strip, and the other end is towards the bottom sealing strip, and the guide groove plays a guiding role on the sealing section.

[0019] Preferably, the sealing section is located at the rear side of the bottom sealing strip, the positioning block is provided with an avoiding opening for avoiding the side sealing strip, the lower part of the side sealing strip is inserted into the avoiding opening, and the part of the positioning block surrounding the avoiding opening forms a water blocking part. The water blocking part can block a large amount of water falling on the door body when washing and spraying, reduce the water surge near the corner, and reduce the sealing pressure.

[0020] In order to facilitate positioning of the positioning block, one way is that the positioning block is connected with the inner container through a connecting piece.

[0021] In order to facilitate positioning of the positioning block, another way is that the inner container is provided with a mounting piece with a Z-shaped cross section, the mounting piece includes a first plate body, a second plate body and a third plate body connected in sequence, the first plate body is mounted on the inner container, the second plate body and the third plate body and the inner wall surface of the inner container together form a containing groove for partially containing the side sealing strip, the positioning block is provided with a card, the lower end of the card is mounted on the positioning block, the upper end of the card extends upward, and the second plate body is provided with a card slot for containing the card. In this way, without additional connecting pieces for fixing the positioning block, only the card on the positioning block and the card slot on the second plate body are needed, and the structure is simple and compact.

[0022] The side sealing strip and the top sealing strip can be designed in a split body, but in order to prevent a sealing dead angle between the upper end of the side sealing strip and the top sealing strip, causing water leakage, the two side sealing strips and the top sealing strip are integrally connected in a U-shaped structure.

[0023] In order to facilitate positioning of the side sealing strip and the top sealing strip, the inner container is provided with a mounting piece with a Z-shaped cross section, the mounting piece includes a first plate body, a second plate body and a third plate body connected in sequence, the first plate body is mounted on the inner container, the second plate body and the third plate body and the inner wall surface of the inner container together form a containing groove, and the containing groove is in a U-shaped structure for partially containing the side sealing strip and the top sealing strip.

[0024] The sealing member can have various structural forms. In order to improve the sealing performance of the sealing member, the sealing member comprises a first mounting portion and a first sealing portion integrally connected thereto. The first sealing portion comprises a first side wall, a second side wall and a third side wall. The third side wall is connected to the first mounting portion. The first side wall and the second side wall are each connected to the third side wall at one end. The other end of the first side wall and the other end of the second side wall are each inclined towards the other end and connected to each other. The first side wall, the second side wall and the third side wall together enclose a first cavity capable of elastic deformation. The other end of the first side wall extends beyond the connection between the first side wall and the second side wall to form a fourth side wall. In the closed state of the door body, the first side wall and the fourth side wall of the sealing member are pressed against the door body. The presence of the second side wall reduces the length of the free end of the first side wall and the fourth side wall as a whole, preventing the first side wall and the fourth side wall from being distorted and affecting the sealing performance in the closed state of the door body.

[0025] The bottom sealing strip comprises a body connected to the bottom of the door body and a sealing fin connected to the body. In the closed state of the door body, the sealing fin is inclined downward and backward. The lower end of the sealing fin abuts against the bottom wall of the inner container. The angle θ between the area in front of the bottom wall of the inner container and the front wall of the sealing fin is an acute angle. In this way, during the opening and closing of the door, the lower end of the sealing fin hardly moves, and only the angle D between the upper end of the sealing fin and the horizontal plane increases with the compression of the sealing fin, so that the lower end of the sealing fin is more firmly pressed against the bottom wall of the inner container, and the sealing performance is good. Moreover, the lower end of the sealing fin and the bottom wall of the inner container are prevented from rubbing against each other to produce an abnormal sound.

[0026] The angle between the fourth side wall and the second side wall is defined as ∠C, and the angle between the third side wall and the second side wall is defined as ∠B. Both ∠B and ∠C are acute angles, and ∠B < ∠C. The first side wall and the fourth side wall are pressed by the door body to compress the first cavity, thereby forming a seal with the door body under the rebound force of the first cavity. Due to the size relationship between ∠B and ∠C, the second side wall is more easily deformed relative to the first side wall and the fourth side wall, thereby enhancing the sealing performance of the first side wall and the fourth side wall and reducing the sealing compression force.

[0027] In order to prevent water from entering the accommodation groove, a sealing lip extending towards the first mounting portion is provided on the third side wall. The sealing lip is located beside the first mounting portion, and a gap is formed between the sealing lip and the outer wall surface of the first mounting portion. In the state that the first mounting portion is accommodated in the accommodation groove, the third plate body is embedded in the gap to form a seal. The sealing lip can prevent water from entering the angle between the sealing arm closest to the opening of the accommodation groove and the sealing head.

[0028] The sealing section can have various structural forms, such as a sealing strip made of rubber. In order to improve the sealing between the sealing section and the bottom sealing strip, the structure of the sealing member is the same as that of the sealing section. The positioning block presses against the first mounting portion of the sealing section. In the closed state of the door body, the first side wall and the fourth side wall of the sealing section press against the bottom sealing strip. In the closed state of the door body, the first side wall and the fourth side wall press against the bottom sealing strip. The first side wall and the fourth side wall are extruded by the bottom sealing strip, and the first cavity is compressed, so as to form a seal with the bottom sealing strip under the rebounding force of the first cavity. Moreover, due to the size relationship between ∠B and ∠C, the second side wall is more easily deformed relative to the first side wall and the fourth side wall, the sealing performance of the first side wall and the fourth side wall is improved, and the sealing compression force is reduced.

[0029] In order to reduce the knocking feeling when the basket is pulled, the left wall surface and the right wall surface of the inner container are provided with guide rails extending in the front-rear direction. The positioning block is located at the front end of the guide rail, and the upper end surface of the positioning block and the guide rail surface of the guide rail jointly form a channel for the basket to slide thereon. When the basket is pushed and pulled, the end of the guide rail and the inner door are empty. When the rollers of the basket move to the end of the guide rail and the inner door, the basket has a knocking feeling when it is pushed and pulled, and the hand feeling is not smooth. The positioning block fills this part of space, improving the pushing and pulling experience of the basket.

[0030] Compared with the prior art, the advantages of the present application are as follows: the sealing section is arranged between the two side sealing strips and the bottom sealing strip, the sealing section connects the side sealing strips and the bottom sealing strip, avoids water leakage at the unconnected part between the side sealing strips and the bottom sealing strip, forms a reliable corner sealing area, can prevent a large amount of water from overflowing during washing, and only a small amount of water can seep out. At the same time, the water vapor generated in the area a) of the front side area of the bottom sealing strip ( Figure 9 、 10 ) is greatly reduced, and the difficulty of preventing water vapor between the inner door and the outer door is reduced.

[0050] The present application will be further described in detail with reference to the following examples in conjunction with the accompanying drawings.

[0051] Example 1 ​​​​​​​​​​​​

[0052] As Figures 1-17 shown, the cleaning machine with sealing structure of the preferred embodiment comprises an inner container 1, a door body 2, a sealing member 3, a bottom sealing strip 4 and a positioning block 5, and the sealing member 3 and the bottom sealing strip 4 jointly constitute the sealing structure.

[0053] As Figures 1-7 , 11 shown, the inner container 1 is open at the front side, and the sealing member 3 is arranged in the inner container 1 and adjacent to the opening of the inner container 1, and the sealing member 3 comprises two vertically extending side sealing strips 31 and a top sealing strip 32 extending leftward and rightward above the two side sealing strips 31, and the top sealing strip 32 is arranged at the top wall of the inner container 1, and the side sealing strips 31 are respectively arranged at the left and right side walls of the inner container 1.

[0054] The side sealing strips 31 and the top sealing strip 32 can be designed in a split body, but in order to prevent the existence of a sealing dead angle between the upper end of the side sealing strip 31 and the top sealing strip 32, resulting in water leakage, in the embodiment, the two side sealing strips 31 and the top sealing strip 32 are integrally formed into a U-shaped sealing member 3. As Figure 4 , 7 shown, the inner container 1 is provided with a mounting member 6 with a Z-shaped cross section, and the mounting member 6 comprises a first plate body 61, a second plate body 62 and a third plate body 63 connected in sequence, the first plate body 61 is arranged on the inner container 1, the second plate body 62 and the third plate body 63 jointly form a containing groove 64 with the inner wall surface of the inner container 1, the containing groove 64 is arranged adjacent to the opening of the inner container 1, and the containing groove 64 is in a U-shaped form matched with the sealing member 3, and the sealing member 3 is partially contained in the containing groove 64.

[0055] As Figure 2 , 8 , 9, 10 shown, the door body 2 is rotatably arranged at the front side of the inner container 1, so as to open or close the opening of the inner container 1.

[0056] The door body 2 comprises an outer door 21 and an inner door 22 connected with each other, the bottom of the inner door 22 is located in the inner container 1, and the upper part of the inner door 22 can be deflected forward and backward relative to the inner container 1, and the rotating connection structure of the door body 2 and the inner container 1 can adopt the existing structure. The lower side edge of the inner door 22 is bent forward and upward to form a bent edge 221, and the bent edge 221 and the front wall surface of the inner door 22 jointly form a recess 222.

[0057] The bottom sealing strip 4 extends along the left and right directions, and the bottom sealing strip 4 comprises a body 41, the upper end of the body 41 is bent downward and rearward to form a second mounting portion 42 which can be arranged in the recess 222, and the lower end of the body 41 is downwardly inclined to form a sealing fin 43.

[0058] In the closed state of the door body 2, the inner door 22 is at least partially embedded in the inner container 1, the side sealing strip 31 and the top sealing strip 32 are pressed against the inner door 22, the sealing fin 43 is inclined from top to bottom and rearward, and the lower end of the sealing fin 43 abuts against the bottom wall of the inner container 1. Thus, in the closed state of the door body 2, the sealing structure is arranged around the contact surface between the door body 2 and the inner container 1, and the sealing performance is good.

[0059] As shown in Figure 10 the closed state of the door body 2, the included angle θ between the bottom wall of the inner container 1 and the front wall 430 of the sealing fin 43 is an acute angle. Thus, in the process of opening and closing the door, the lower end of the sealing fin 43 hardly moves, and only the included angle D between the upper end of the sealing fin 43 and the horizontal plane increases with the compression of the sealing fin 43, so that the lower end of the sealing fin 43 is more firmly pressed against the bottom wall of the inner container 1, the sealing performance is good, and the friction between the lower end of the sealing fin 43 and the bottom wall of the inner container 1 is avoided to generate abnormal sound. Preferably, 40°<θ<70°. If the angle is too large, the lower end of the sealing fin 43 is easily moved under the impact of water flow, which affects the sealing performance and generates noise. If the angle is too small, the included angle D between the upper end of the sealing fin 43 and the horizontal plane is not easily changed, which affects the firmness of the lower end of the sealing fin 43 pressed against the bottom wall of the inner container 1.

[0060] In addition, the body 41 is formed with a sealing flap 44 below the second mounting portion 42. In the state that the second mounting portion 42 is embedded in the embedding groove 222, the sealing flap 44 covers the bottom wall of the inner door 22, and the sealing flap 44 can prevent water from entering the embedding groove 222 from the gap between the bottom wall of the inner door 22 and the body 41.

[0061] As shown in Figures 8-12 the closed state of the door body 2, because there is a gap between the end of the bottom sealing strip 4 and the lower end of the corresponding side sealing strip 31, there is a sealing dead angle between the side sealing strip 31 and the bottom sealing strip 4. Therefore, a sealing section 33 is arranged between each side sealing strip 31 and the bottom sealing strip 4. In the closed state of the door body 2, the sealing section 33 is pressed against the bottom wall of the inner container 1, one end of the sealing section 33 is connected to or abuts against the corresponding side sealing strip 31, and the other end of the sealing section 33 is connected to or abuts against the bottom sealing strip 4.

[0062] As shown in Figure 9 in the embodiment, the lower end of the side sealing strip 31 is transversely bent to extend to form the above-mentioned sealing section 33. The free end of the sealing section 33 abuts against the bottom sealing strip 4 to connect the side sealing strip 31 and the bottom sealing strip 4, so as to prevent water from leaking from the gap between the two.

[0063] The two ends of the bottom sealing strip 4 abut against the wall of the corresponding side of the inner container 1 to form a seal. In the embodiment, as shown in Figure 17As shown, the left and right ends of the sealing fin 43 extend to the junction with the sealing section 33. Both ends of the bottom wall of the inner liner 1 have rounded corners 11. Both ends of the sealing fin 43 can be placed within the corresponding rounded corners 11, and both ends of the sealing fin 43 have an arc-shaped structure 431 that matches the corresponding rounded corners 11. The matching shape of the two ends of the sealing fin 43 with the two ends of the inner liner 1 improves sealing reliability. Even if a small amount of water leaks out at the junction of the sealing section 33 and the sealing fin 43, the fit between the two ends of the sealing fin 43 and the rounded corners 11 forms a second barrier, further preventing water leakage from the corners.

[0064] like Figure 9 , 13 As shown in Figure 15, the positioning block 5 is fixedly installed in the inner liner 1. The positioning block 5 can be made of plastic. The positioning block 5 is connected to the inner liner 1 through a connector (such as a screw) installed in the connecting hole 50. Specifically, in this embodiment, since the door body 2 and the inner liner 1 are rotatably connected through a hinge structure, a hinge support block (not shown in the figure) is provided to support the hinge. The hinge support block is attached to the outer wall surface of the inner liner 1. The screw passes through the hinge support block, the inner liner 1 and the screw hole and is connected. Of course, the screw can also be directly passed through the inner liner 1 and connected to the screw hole.

[0065] The bottom of the positioning block 5 is provided with a guide groove 51 for the sealing section 33 to pass through. One end of the guide groove 51 faces the lower end of the side sealing strip 31, and the other end faces the bottom sealing strip 4. This means that the positioning block 5 presses on the upper surface of the sealing section 33, which serves to position the sealing section 33 and prevent the sealing section 33 from shifting vertically, thus affecting its firmness against the bottom sealing strip 4 and consequently affecting the sealing effect.

[0066] like Figure 9 , 14 As shown, in this embodiment, the sealing section 33 is located behind the bottom sealing strip 4, and the positioning block 5 is provided with an avoidance opening 53 to avoid the side sealing strip. The portion of the positioning block 5 that forms the avoidance opening 53 forms a water-blocking part 52. The water-blocking part 52 can block a large amount of water that sprays onto the door body 2 during washing and spraying, thereby reducing the water surging near the corner and reducing the sealing pressure.

[0067] like Figure 9 As shown, in addition to the function of the positioning and sealing section 33 mentioned above, the positioning block 5 also has the following functions: Guide rails 12 extending in the front-to-back direction are provided on both the left and right walls of the inner liner 1. The positioning block 5 is located at the front end of the guide rail 12, and the upper end face of the positioning block 5 and the upper end face of the guide rail 12 together form a channel for the bowl basket to slide on. When the bowl basket is pushed or pulled, there is a gap between the end of the guide rail 12 and the inner door 22. When the rollers of the bowl basket move to the gap between the end of the guide rail 12 and the inner door 22, the bowl basket feels bumpy and the feel is not smooth. The positioning block 5 fills this gap, improving the experience of pushing and pulling the bowl basket.

[0068] In this embodiment, the sealing element 3 and the sealing section 33 have the same structure, and the sealing section 33 will be described here:

[0069] like Figure 12 As shown, the sealing section 33 includes an integrally connected first mounting part 7 and a first sealing part 8. The first mounting part 7 passes through the guide groove 51 of the positioning block 5. A sealing arm 71 is provided on the outer wall surface of the first mounting part 7. The sealing arm 71 is inclined away from the first mounting part 7 along the direction from the first mounting part 7 to the first sealing part 8. The included angle between the sealing arm 71 and the outer wall surface of the first mounting part 7 is an acute angle. Because the sealing arm 71 is deformable, it will be in close contact with the positioning block 5, preventing the first mounting part 7 from moving relative to the positioning block 5 and affecting the sealing performance.

[0070] The first sealing part 8 includes a first sidewall 81, a second sidewall 82, a third sidewall 83, a fourth sidewall 84, a fifth sidewall 85, and a sixth sidewall 86. The third sidewall 83 is connected to the first mounting part 7. One end of the first sidewall 81 and the second sidewall 82 are both connected to the third sidewall 83. Specifically, in this embodiment, the first sidewall 81 and the third sidewall 83 are connected through the fifth sidewall 85, and the second sidewall 82 and the third sidewall 83 are connected through the sixth sidewall 86. The other ends of the first sidewall 81 and the second sidewall 82 are inclined towards each other and connected. The first sidewall 81, the second sidewall 82, the third sidewall 83, the fifth sidewall 85, and the sixth sidewall 86 together form a first cavity 87 that can be elastically deformed. The other end of the first sidewall 81 extends out to form the fourth sidewall 84 at its connection with the second sidewall 82. The thickness of the second sidewall 82 is less than the thickness of the first sidewall 81 and the fourth sidewall 84.

[0071] Of course, the first sidewall 81 can be directly connected to the third sidewall 83, and the second sidewall 82 can be directly connected to the third sidewall 83.

[0072] The included angle between the fourth sidewall 84 and the second sidewall 82 is defined as ∠C, the included angle between the third sidewall 83 and the second sidewall 82 is defined as ∠B, both ∠B and ∠C are acute angles, and ∠B < ∠C, the included angle between the third sidewall 83 and the first sidewall 81 is defined as ∠E, and 35° < ∠E < 50°. Figure 12 The angles ∠B, ∠C, and ∠E are marked on the top sealing strip 32, and the angle of the sealing section 33 is the same as that of the top sealing strip 32.
