Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, the present embodiment provides a dishwasher, which includes a machine body 1 and a door body, wherein the machine body 1 is rotatably connected to the door body, the door body is rotatably arranged on the machine body 1 to open or close the opening 11, and a sealing member is arranged between the machine body 1 and the door body. When the door is opened, the tableware can be put into the machine body 1 from the opening 11; when the door is closed, the machine body 1 and the door body are matched to form a sealed cleaning cavity so as to clean tableware.

As shown in fig. 3, 8 and 9, the sealing member includes a side sealing member 3, the side sealing member 3 includes a first fixing portion 31 and a first sealing portion 32, one of the machine body 1 and the door body is provided with a first mounting groove 14, and the other of the machine body 1 and the door body is provided with a first sealing surface 21. When the side sealing element is installed, the first fixing portion 31 is installed in the first installation groove 14, the first sealing portion 32 protrudes out of the first installation groove 14, and the side sealing element 3 is positioned and fixed through the first fixing portion 31. When the door is closed, the end face 321 of the first sealing portion 32 and the first sealing surface 21 are pressed against each other to achieve sealing.

Further, the first sealing surface 21 is provided with a sealing rib 22 extending toward the side seal 3, and the sealing rib 22 is located inside the side seal 3 (inner toward the center of the dishwasher and outer toward the center of the dishwasher), and presses against the first side wall surface 322 of the first sealing portion 32 to achieve sealing.

A first resealing is achieved by the mutual compression of the end face 321 of the first seal portion 32 and the first seal surface 21, and a further resealing is achieved by the mutual compression of the seal rib 22 and the first side wall surface 322 of the first seal portion 32. Namely, the double sealing between the door body and the machine body 1 is realized through the side sealing piece 3, the sealing effect between the door body and the machine body 1 is effectively ensured, and the dish-washing machine is watertight and airtight in the long-time working process.

Furthermore, the sealing rib 22 located inside the side seal 3 also has a water blocking function, and prevents water from directly impacting the joint surface between the first sealing surface 21 and the end surface of the first sealing portion 32, which may cause water leakage at the joint surface.

In a specific example, the first mounting groove 14 is provided on the body 1, and the first sealing surface 21 is provided on the door body.

As shown in fig. 3, the machine body 1 includes a fixing frame 13 and an inner container 12, which are fixedly connected, and the fixing frame 13 and the inner container 12 cooperate to form a first mounting groove 14. The first mounting groove 14 can be formed by assembling the fixing frame 13 and the inner container 12, or can be directly formed by demolding.

The first fixing portion 31 of the side sealing member 3 is fixed in the first mounting groove 14, the first sealing portion 32 is located outside the first mounting groove 14, and the first sealing portion 32 is in press-contact with the end surface at the notch of the first mounting groove 14. The door body comprises an inner door frame 2, a first sealing surface 21 and a sealing rib 22 are arranged on the inner door frame 2, and the first sealing surface 21 and the end surface 321 of the side sealing piece 3 are in press fit to realize sealing.

Alternatively, as shown in fig. 3 and 9, a first concave portion 323 is provided on the first side wall surface 322 of the first sealing portion 32, and an edge of the first concave portion 323 is press-sealed with the sealing rib 22.

Therefore, the first side wall surface 322 and the sealing rib 22 are fully sealed, the contact area is reduced as much as possible, and the door closing force is avoided.

Alternatively, as shown in fig. 3, the seal rib 22 extends toward the side seal 3, and the end surface of the seal rib 22 does not exceed the notch of the first mounting groove 14.

Specifically, as shown in fig. 3, after the door is closed, the sealing rib 22 located inside the side sealing member 3 extends toward the side where the side sealing member 3 and the machine body are located, and the end surface 221 of the sealing rib 22 does not exceed the end surface at the notch of the first mounting groove 14, that is, the end surface 221 of the sealing rib 22 is located on the side, close to the inner frame 2, of the end surface at the notch of the first mounting groove 14.

If the sealing rib 22 extends beyond the notch of the first mounting groove 14, the sealing rib 22 needs to be inserted into the inner side of the groove wall of the first mounting groove 14, so that in order to avoid interference between the sealing rib 22 and the groove wall of the first mounting groove 14, a gap needs to be provided between the sealing rib 22 and the groove wall of the first mounting groove 14, which affects the sealing effect between the sealing rib 22 and the first side wall surface 322 of the side sealing member 3, and affects the water blocking effect of the sealing rib 22. The sealing rib 22 of the present embodiment is not inserted into the inner side of the groove wall of the first mounting groove 14, so that the gap between the sealing rib 22 and the first side wall surface 322 can be adjusted to be minimum, and thus after closing the door, the sealing rib 22 can be in contact with the first side wall surface 322 of the side sealing member 3, and the sealing and water retaining effects are better.

Alternatively, as shown in fig. 3 and 9, the first sealing portion 32 is provided with a first rib 324, and the connecting portion of the sealing rib 22 and the first sealing surface 21 is sealed by pressing the first rib 324.

Specifically, as shown in fig. 3, the first rib 324 is provided at a connecting portion of the first side wall surface 322 and the end surface 321, and the first rib 324 is provided obliquely. After closing the door, a triangular area is formed between the sealing rib 22 and the first side wall surface 322 of the side sealing member 3, and two contact points exist in the area, one is the contact point between the sealing rib 22 and the first side wall surface 322, and the other is the contact point between the first convex rib 324 and the root of the sealing rib 22. The structure ensures the sufficient sealing of two points, reduces the contact area as much as possible and avoids the door closing force.

Alternatively, as shown in fig. 3 and 9, the first sealing portion 32 is further provided with a second rib 326, the second rib 326 is located outside the first rib 324, and the second rib 326 is in compression sealing with the first sealing surface 21.

Specifically, as shown in fig. 3, the end face 321 of the first sealing portion 32 is provided with a second rib 326. When the door is closed, the second rib 326 is just in pressing contact with the middle position of the first sealing surface 21, so that sealing is realized.

Alternatively, as shown in fig. 3, the end surface of the protruding end of the first rib 324 may be spherical 325, and the end surface of the protruding end of the second rib 326 may also be spherical.

The side seal 3 is provided with a first rib 324 and a second rib 326. In the closed state, the first rib 324, the root of the sealing rib 22 and the first sealing surface 21 form a reliable sealing area, and the second rib 326 contacts the first sealing surface 21. In the closing process, the sealing rib 22 first contacts with the first rib 324, and the door can be closed smoothly even if the sealing rib 22 and the first rib 324 of the side seal 3 interfere with each other to a certain extent due to the fact that the end surface of the first rib 324 is a spherical surface 325. However, if the gap between the first rib 324 and the sealing rib 22 is slightly larger due to product error, although the first sealing surface 21 and the second rib 326 are press-fitted, there is a possibility of water leakage. In this regard, a second rib 326 is provided on the side seal 3. After closing, the second rib 326 is located at the middle position of the first sealing surface 21, so as to achieve the effective sealing effect.

Therefore, the sealing rib 22 is sealed with the first side wall surface 322 of the side sealing member 3, the first rib 324 is sealed with the root of the sealing rib 22 and the first sealing surface 21 on the door inner frame 2, and the second rib 326 is sealed with the first sealing surface 21, and the triple sealing structure strictly ensures the reliability of sealing between the door body and the machine body 1, and achieves the purposes of no water leakage and no air leakage.

Alternatively, as shown in fig. 3 and 9, a second concave portion 328 is provided on a second side wall surface 327 of the first sealing portion 32 opposite to the first side wall surface 322, and the first concave portion 323 and the second concave portion 328 are both V-shaped. However, the recess depths of the first recess 323 and the second recess 328 are different, or the recess lowest points of the first recess 323 and the second recess 328 are not on the same cross section, so that the first recess 323 and the second recess 328 are asymmetrically disposed.

Specifically, as shown in fig. 3 and 9, due to the presence of the first and second recessed

portions

323 and 328, the first sealing portion 32 of the side seal 3 can be generally regarded as being composed of two "Σ" shaped structures with opposite openings. The lowest concave points of the first concave portion 323 and the second concave portion 328 (i.e., the bending points of the first concave portion 323 and the second concave portion 328) are not on the same cross section, and the lowest concave point of the first concave portion 323 is located on the side of the lowest concave point of the second concave portion 328 close to the first sealing surface 21, so that the two sigma-shaped structures constituting the first sealing portion 32 are asymmetric. Compared with the first sealing part 32 which is composed of two symmetrically-arranged sigma-shaped structures, the two sigma-shaped structures bear force simultaneously, and the force is divided equally by the two sigma-shaped structures, when the first sealing part 32 of the embodiment bears force, the sigma-shaped structure where the first concave part 323 is firstly bearing force independently, and the first sealing part 32 is easier to bend and compress. Therefore, at a certain hardness of the side seal 3, in case of a certain interference of the side seal itself, the easier compression means a smoother closing of the door, otherwise the easier compression may cause a difficult closing or even a failure of the closing of the door.

Of course, besides the two "Σ" shaped structures being arranged asymmetrically, there may be other ways to make the two "Σ" shaped structures not stressed at the same time during the closing process.

For example: the end surface 321 of the first seal portion 32 is an inclined surface, and is gradually inclined toward the first seal surface 21 in a direction toward the first bead 324. Alternatively, the first ribs 324 may have a greater protrusion height than the second ribs 326. So set up for closing the door in-process, the "Σ" shape structure at first of first sunk part 323 place bears the force alone for compression deformation is changeed to first sealing 32, and the process of closing the door is more smooth and easy.

Alternatively, as shown in fig. 3 and 9, the first fixing portion 31 is provided with a positioning rib 311, and a protruding end of the fixing rib 311 is inclined toward the notch direction of the first mounting groove 14.

Specifically, as shown in fig. 3 and 9, the two V-shaped fixing ribs 311 are disposed on the side wall of the first fixing portion 31, so that the first fixing portion 31 can be easily inserted into the first mounting groove 14, and the side sealing member 3 can be reliably mounted with a certain holding force in the direction opposite to the insertion direction.

Optionally, as shown in fig. 3 and 9, a cavity 329 is provided in the first sealing portion 32. The cavity 329 enables the first sealing part 32 to have better elasticity and deform easily, so that the first sealing part 32 is more fully in extrusion contact with the first sealing surface 21 and the sealing rib 22, the sealing effect is enhanced, water leakage is prevented, the force applied when the door is closed can be reduced, and the door is convenient to close.

Alternatively, the side seals 3 are provided on the upper, left and right sides of the opening 11. Specifically, as shown in fig. 8, the side seal 3 is an integral structure having a U-shape as a whole, and seals between the door body and the machine body on the upper side, the left side, and the right side are realized.

Optionally, as shown in fig. 2, 4-7, the sealing member further includes a bottom sealing member 4 disposed at a lower side of the opening 11 to achieve sealing between the door body and the machine body 1 at the bottom side.

As shown in fig. 4, 10, and 11, the bottom seal member 4 has a cross section in a laterally placed U shape, and the bottom seal member 4 includes a second fixing portion 41 located above and a second sealing portion 42 located below. One of the machine body and the door body is provided with a second mounting groove 23, the other of the machine body 1 and the door body is provided with a second sealing surface 15, and a second fixing part 41 is mounted in the second mounting groove 23 so as to realize the positioning and fixing of the bottom sealing part 4; the second sealing portion 42 is located below the second mounting groove 23, and the lower portion of the second sealing portion 42 and the second sealing surface 15 are pressed against each other to achieve sealing.

Specifically, as shown in fig. 4, 7 and 13, the door inner frame 2 of the door body is provided with a second mounting groove 23, and the bottom wall of the inner container 12 of the machine body 1 is provided with a second sealing surface 15. After closing the door, the bottom 421 of the second sealing portion 42 is pre-press sealed with the second sealing surface 15 of the inner container 12.

When the door is opened, the frictional force F applied by the second sealing surface 15 to the bottom surface 421 of the bottom sealing member 4, which tends to move the second fixing portion 41 toward the notch of the second mounting groove 23, is directed as indicated by the arrow in fig. 4. When the door is closed, the direction of the frictional force applied to the bottom seal member 4 by the second sealing surface 15 is opposite to the direction indicated by the arrow in fig. 4, so that the second fixing portion 41 tends to move toward the inside of the second mounting groove 23. Therefore, the bottom sealing element 4 resists pulling force when the door is opened and receives pretightening force when the door is closed, which excellently ensures the installation and positioning of the bottom sealing element 4 for the dish washing machine which needs to open and close the door frequently.

Alternatively, as shown in fig. 4 and 11, a fixing rib 411 is provided on a side wall of the second fixing portion 41, and a protruding end of the fixing rib 411 is inclined toward a notch direction of the second mounting groove 23.

Alternatively, as shown in fig. 4, the bottom surface 421 of the second sealing portion 42 is parallel to the second sealing surface 15, so that the interference between the two is small, and a small frictional resistance between the bottom sealing member 4 and the second sealing surface 15 is ensured when the door is opened or closed, thereby facilitating the opening and closing of the door.

Alternatively, as shown in fig. 4 and 11, a sealing rib 422 is provided on a bottom surface 421 of the second sealing portion 42.

Specifically, as shown in fig. 4, two sealing ribs 422 are provided on the contact portion between the bottom surface 421 of the second sealing portion 42 and the second sealing surface 15, so as to ensure reliable pre-pressing between the bottom sealing member 4 and the liner 12, and simultaneously prevent the contact between the bottom surface 421 and the second sealing surface 15 from generating large friction force.

Alternatively, as shown in fig. 4 and 11, a cavity 423 is provided in the second sealing part 42. The cavity 423 enables the second sealing portion 42 to have better elasticity and to deform easily, on one hand, the second sealing portion 42 is in more sufficient extrusion contact with the second sealing surface 15, the sealing effect is enhanced, water leakage is prevented, on the other hand, the force applied when the door is closed can be reduced, and the door is convenient to close.
