Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and particularly to a dishwasher. Background Art

[0002] Generally, guide rails are provided on the inner liner of a dishwasher. The guide rails are slidably connected to the inner liner, and the bowl basket is connected to the guide rails. As the guide rails move, the bowl basket can be pushed into and pulled out of the inner liner. In traditional dishwashers, the bowl basket and the guide rails are fixed together by fasteners, and the bowl basket is only sent out of the inner liner along with the movement of the guide rails. As a result, the distance that the bowl basket is pulled out is relatively short. Summary of the Invention

[0048] The realization of the object, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] It should be noted that if there are directional indications (such as up, down, left, right, front, back, etc.) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, then such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] The present invention provides a dishwasher, which includes a body and a door body connected to each other.

[0053] Please refer to Figure 1 , wherein, the body forms a receiving cavity with one side open. A bowl basket 40 can be arranged in the receiving cavity, and the bowl basket 40 is used for loading tableware. In addition, a spray arm can also be arranged in the receiving cavity to spray water towards the bowl basket 40 for cleaning tableware. Spray arms can be arranged both above and below the bowl basket 40 to achieve water spraying in multiple directions. Generally, the body may include an inner liner 10 and a housing, and the inner liner 10 forms the receiving cavity, and the housing wraps around the outside of the inner liner 10.

[0054] The door body 50 covers the open mouth of the receiving cavity. For example, in one embodiment, the open mouth of the receiving cavity faces forward, and the door body 50 is arranged on the front side of the body. The door body 50 and the body can be rotatably connected. For example, the bottom of the door body 50 is rotatably connected to the body, and the door body 50 can be turned up and down to open or cover the open mouth of the body. Or, the left side of the door body 50 is rotatably connected to the body. In addition, in other embodiments, other connection methods can also be adopted between the door body 50 and the body, and the embodiments of the present invention do not limit this.

[0055] Please refer to in combination Figure 2 , the dishwasher further includes a first guide rail 20 and a second guide rail 30. The first guide rail 20 is installed on the inner liner 10, and the second guide rail 30 is slidably connected to the first guide rail 20 to be able to slide in the front-rear direction. The bowl basket 40 is slidably connected to the second guide rail 30 and can slide in the front-rear direction.

[0056] Among them, the first guide rail 20 can be slidably connected to the inner container 10 so as to be able to slide relative to the inner container 10 in the front-back direction, so that the bowl basket 40 can be pulled out a greater distance. Of course, the first guide rail 20 can also be fixed relative to the inner container 10, and the bowl basket 40 is pulled out of the inner container 10 only by its own movement and the movement of the second guide rail 30.

[0057] The bowl basket 40 is slidably connected to the second guide rail 30, which means that the bowl basket 40 itself is slidably connected to the second guide rail 30, rather than being slidably connected through other slide rail structures.

[0058] In the present invention, the bowl basket 40 moves back and forth relative to the inner container 10 not only by relying on the sliding of the second guide rail 30 relative to the first guide rail 20, but also by the sliding cooperation between the bowl basket 40 itself and the second guide rail 30. It is equivalent to that the second guide rail 30 forms a movable guide rail, and the bowl basket 40 itself forms a movable guide rail. The two movable guide rails act simultaneously, so that the bowl basket 40 can be pulled out a farther distance.

[0059] In traditional dishwashers, in order to pull out the bowl basket 40 a farther distance, more guide rails are often set by increasing the number of movable guide rails, and the bowl basket 40 is completely pulled out by the movement of the guide rail itself. This way will occupy too much width of the inner container 10 in the left-right direction, squeezing the installation space of the bowl basket 40 and making the bowl basket 40 smaller in volume. In the present invention, by forming a guide rail by the bowl basket 40 itself, the setting of the guide rail can be reduced, and the space in the width direction of the inner container 10 can be fully utilized.

[0060] Please refer to Figures 3 to 10 In one embodiment, the first guide rail 20 includes a mounting plate 21, and a support rib extending in the front-back direction is convexly provided on the mounting plate 21. A mating rib 31 extending in the front-back direction is convexly provided on the second guide rail 30, and the mating rib 31 can slide on the upper surface of the support rib. Among them, a plurality of support ribs can be provided on the mounting plate 21, and the plurality of support ribs are spaced apart in the up-down direction. Correspondingly, a mating rib 31 can be provided on the second guide rail 30 corresponding to each support rib. Among the corresponding support rib and mating rib 31, the mating rib 31 slides in the front-back direction on the upper surface of the support rib. In this way, the support rib supports the mating rib 31 to prevent the second guide rail 30 from falling down. In addition, the setting of the plurality of support ribs and the plurality of mating ribs 31 can make the second guide rail 30 be supported more tightly in the up-down direction, thereby preventing it from shaking.

[0061] In addition, in other embodiments, a chute can also be provided on the mounting plate 21, and the mating rib 31 slides in the chute.

[0062] To prevent the second guide rail 30 from sliding forward out of the first guide rail 20, in one embodiment, a second front stop 25 is further provided on the mounting plate 21, and a third front stop 32 is provided on the second guide rail 30. After the second guide rail 30 slides forward in place, the front surface of the third front stop 32 abuts against the second front stop 25, thereby restricting the second guide rail 30 from continuing to slide forward. Among them, the second front stop 25 can be a convex column, a roller or a convex strip, etc. For example, as Figure 7 shown, the second front stop 25 is a convex block integrally provided with the supporting rib, and the second front stop 25 can be provided on the upper surface of the supporting rib. Or, as Figure 8 and Figure 9 shown, the second front stop 25 is a roller rotatably connected to the supporting rib. Of course, the second front stop 25 can also be provided at a position near the top of the first guide rail 20, and the second front stop 25 can also be rotatably connected to the mounting plate 21.

[0063] Similarly, the third front stop 32 can also be a convex column, a roller or a convex strip, etc. In one embodiment, the third front stop 32 is in the shape of a long strip extending in the front-rear direction, and the front surface of the third front stop 32 is a limiting surface 322, and this limiting surface 322 can abut against the rear side of the second front stop 25.

[0064] In one embodiment, the third front stop 32 constitutes one of the mating ribs 31 and is slidably connected to one of the supporting ribs. For example, two supporting ribs are provided on the mounting plate 21, one of the supporting ribs is the first rib 22, and the other supporting rib is the second rib 23. The second rib 23 is located above the first rib 22, and the second front stop 25 is provided above the second rib 23. The mating rib 31 can slide on the upper surface of the first rib 22, and the third front stop 32 can slide on the upper surface of the second rib 23. After the second guide rail 30 slides in place, the front surface of the third front stop 32 abuts against the second front stop 25.

[0065] In this embodiment, by using one of the mating ribs 31 as the form of the third front stop 32, the structural complexity of the second guide rail 30 can be reduced, which is beneficial to reducing the production cost and processing difficulty.

[0066] Please refer to Figure 10 again. To reduce the resistance of the second guide rail 30 to slide, in one embodiment, a convex portion 321 is provided on the lower surface of the third front stop 32, and the convex portion 321 contacts the upper surface of the second rib 23. In this way, the third front stop 32 only contacts the second rib 23 by relying on the convex portion 321, reducing the contact area with the second rib 23 and making the sliding of the second guide rail 30 smoother. Optionally, the convex portion 321 is provided at the rear end of the third front stop 32.

[0067] Please refer to again Figure 7 , to prevent the second guide rail 30 from sliding out backward from the first guide rail 20. In one embodiment, at least one second rear stop 26 is further provided on the first guide rail 20. After the second guide rail 30 slides backward to the in-place position, the second guide rail 30 can abut against the front surface of the second rear stop 26. Specifically, a convex block can be provided on the second guide rail 30 to abut against the second rear stop 26, or the rear surface of the second guide rail 30 directly abuts against the second rear stop 26.

[0068] In one embodiment, a second rear stop 26 is provided at the rear end of both the first rib 22 and the second rib 23. The second rear stop 26 protrudes from the upper surface of the first rib 22 or the second rib 23. The rear surface of the second guide rail 30 can abut against the second rear stop 26, thereby restricting the second guide rail 30 from sliding out backward.

[0069] Please refer to again Figure 4 、 Figure 7 , to prevent the second guide rail 30 from detaching from the first guide rail 20 in the left-right direction. In one embodiment, a limiting groove is further provided on the first guide rail 20. The opening of the limiting groove faces upward or downward. The second guide rail 30 is further provided with a limiting rib 33, and the limiting rib 33 is installed in the limiting groove. Specifically, the upper end of the second guide rail 30 extends upward to form the limiting rib 33, and the limiting rib 33 extends in a long strip shape in the front-rear direction. A retaining edge 271 is provided on the top surface of the mounting plate 21. The retaining edge 271 protrudes toward the side where the second guide rail 30 is located. A limiting wall 272 is provided on the retaining edge 271. The limiting wall 272 protrudes downward from the retaining edge 271. A space is formed between the limiting wall 272 and the mounting plate 21 to constitute the limiting groove. The limiting rib 33 is inserted into the limiting groove from bottom to top, and the limiting wall 272 can prevent the limiting rib 33 from moving in the direction away from the mounting plate 21. In addition, a plurality of limiting walls 272 can be provided on the retaining edge 271, and the plurality of limiting walls 272 are spaced apart in the front-rear direction.

[0070] Please refer to Figure 11 、 Figure 12A 、 Figure 12B and Figure 13 , in one embodiment, a plurality of guiding surfaces 331 are provided on the side of the limiting rib 33 facing the bowl basket. A part of the guiding surfaces 331 incline toward the side where the bowl basket is located in the direction from front to back (such as Figure 12A 、 Figure 13 the rear guiding surface 331 in), so that during the process of pulling the second guide rail 30 outwards, these guiding surfaces can play a guiding role and facilitate the limiting rib 33 to slide into the limiting groove between the limiting wall 272 and the mounting plate 21. Another part of the guiding surfaces incline in the direction from front to back toward the direction away from the bowl basket (such as Figure 12B 、 Figure 13The guiding surfaces 331) on the front side, so that during the inward pushing process of the second guide rail 30, these guiding surfaces can play a guiding effect, facilitating the limiting convex edge 33 to slide into the limiting groove between the limiting wall 272 and the mounting plate 21.

[0071] Please refer back to Figure 7 , in one embodiment, a relief notch 24 is provided on the supporting rib, so that the supporting rib is divided into front and rear sections. When the second guide rail 30 moves forward until its rear end is located at the relief notch 24, the rear end of the second guide rail 30 can rotate downward within the relief notch 24, so that the third front stopper 32 can bypass the second front stopper 25 upward, so that the second guide rail 30 can be pulled out obliquely upward. Specifically, the relief notch 24 divides both the first rib 22 and the second rib 23 into front and rear sections respectively. The intervals between the front and rear sections of the first rib 22 and the intervals between the front and rear sections of the second rib 23 should correspond to each other in the vertical direction. When the rear end of the second guide rail 30 slides into this interval, by lifting the bowl basket 40 upward, the front end of the second guide rail 30 can be lifted upward, then the rear end of the second guide rail 30 rotates downward until the third front stopper 32 on the second guide rail 30 crosses the second front stopper 25 on the first guide rail 20 upward. After that, the second front stopper 25 no longer blocks the third front stopper 32. At this time, the bowl basket 40 and the second guide rail 30 can be pulled out together. In this embodiment, the relief notch 24 provides sufficient clearance for the movement of the second guide rail 30, so that the second guide rail 30 has enough space to flip here and will not be blocked by the first guide rail 20, so that the entire bowl basket 40 can be taken out smoothly.

[0072] When the second front stopper 25 is a roller, during the process of the third front stopper 32 crossing the roller upward, the roller changes the friction with the third front stopper 32 into rolling friction through its own rolling, which can reduce the frictional force and facilitate the extraction of the second guide rail 30.

[0073] , in one embodiment, a mounting position 28 is provided on the first guide rail 20, and the mounting position 28 is connected to the inner liner. For example, the mounting position 28 is connected to the inner liner by screws. To ensure the strength of the first guide rail 20, the mounting position 28 protrudes from the mounting plate 21. Correspondingly, an avoidance opening 383 (as Figure 10 shown) is provided on the second guide rail 30. When the rear end of the second guide rail 30 slides into the relief notch 24, the avoidance opening 383 corresponds to the mounting position 28 and gives way to the mounting position 28 to prevent interference between the second guide rail 30 and the mounting position 28 during the rotation process.

[0074] In one embodiment, the first guide rail 20 is fixed on the inner container 10 and is immovable relative to the inner container 10. For example, the first guide rail 20 is a plastic part and is integrally injection-molded with the inner container 10, which can simplify the installation. In addition, the first guide rail 20 can also be a sheet metal part. The first guide rail 20 can also be connected to the inner container 10 in other ways. For example, the first guide rail 20 is connected to the inner container 10 by screws or snaps.

[0075] In one embodiment, the first guide rail 20 is slidably connected to the inner container 10 to be able to slide back and forth. After such a setting, the bowl basket 40 can be pulled out to a farther distance.

[0076] Please refer to Figure 2 、 Figure 11 、 Figures 14 to 17 In one embodiment, the second guide rail 30 includes a connecting plate 34. On the connecting plate 34 and at intervals in the front-rear direction, a plurality of groups of limiting mechanisms 35 are provided. Each group of the limiting mechanisms 35 includes two first limiting protrusions 351 spaced up and down. The interval between the two first limiting protrusions 351 forms a sliding gap; the sliding gaps of the plurality of groups of the first limiting mechanisms 35 together form a chute, and the bowl basket 40 is slidably connected to the chute. The chute formed in this way is not a continuous groove part, but is composed of a plurality of sliding gaps spaced in the front-rear direction. While playing a guiding role in the front-rear movement of the bowl basket 40, it can also reduce the contact area with the bowl basket 40, making the movement of the bowl basket 40 smoother.

[0077] On the connecting plate 34 and also at intervals in the front-rear direction, a plurality of second limiting protrusions 36 are provided. The second limiting protrusions 36 are bent upward to form an upward-open receiving gap with the connecting plate 34. The plurality of receiving gaps together form another chute, and the bowl basket 40 is slidably connected to the chute. In this embodiment, the second limiting protrusions 36 can support the bowl basket 40 to prevent the bowl basket 40 from falling down. At the same time, the bent part of the second limiting protrusions 36 can prevent the bowl basket 40 from disengaging from the second guide rail 30 in the left-right direction.

[0078] In this embodiment, the chute formed by the limiting mechanism 35 and the chute formed by the second limiting protrusions 36 are spaced in the up-down direction. In this way, the bowl basket 40 has a plurality of sliding connection positions distributed in the up-down direction with the second guide rail 30, which can make the movement of the bowl basket 40 more stable.

[0079] In one embodiment, the bowl basket 40 is formed by combining a plurality of bowl basket bars. The bowl basket 40 can adopt a metal structure, then the bowl basket bars are metal bars, for example, they can be stainless steel bars.

[0080] In one embodiment, a chute extending in the front-rear direction is formed on the second guide rail 30. The plurality of bowl basket bars include a first bowl basket bar 41 extending in the front-rear direction, and the first bowl basket bar 41 is slidably connected to the chute. By using the bowl basket bars of the bowl basket 40 itself to slidably connect with the second guide rail 30, the bowl basket bars themselves have relatively high strength and small diameters. Therefore, while ensuring a relatively large connection strength with the second guide rail 30, the space occupied in the left-right direction of the inner liner 10 can be reduced. In addition, the chute in this embodiment includes the chute formed by the above-mentioned limiting mechanism 35 and the chute formed by the second limiting protrusion 36, that is, there are two first bowl basket bars 41 on the same side of the bowl basket 40, and the two first bowl basket bars 41 are correspondingly slidably connected to the two chutes. In addition, a chute can also be directly opened on the connecting plate 34, and the chute is a continuous groove extending in the front-rear direction.

[0081] In traditional dishwashers, rollers are provided on the bowl basket 40 to connect with the guide rail. The way of the cooperation between the rollers and the guide rail is prone to relatively large shaking, resulting in the tableware in the bowl basket 40 colliding and breaking with each other. In this embodiment, the bowl basket bars of the bowl basket 40 itself are used to slidably cooperate with the second guide rail 30, and multiple positions of the bowl basket bars can contact the chute. Therefore, the shaking of the bowl basket 40 can be reduced or even avoided.

[0082] In one embodiment, a third limiting protrusion 37 is further provided on the connecting plate 34, and the third limiting protrusion 37 supports the bottom surface and / or the top surface of the first bowl basket bar 41. Specifically, in one embodiment, the third limiting protrusion 37 is provided on the bottom surface of the first bowl basket bar 41, which can further support the bowl basket 40 and prevent the bowl basket 40 from falling. In one embodiment, the third limiting protrusion 37 is provided on the top surface of the first bowl basket bar 41, and the third limiting protrusion 37 can prevent the bowl basket 40 from shaking upwards. In one embodiment, the third limiting protrusion 37 is provided on both the bottom surface and the top surface of the first bowl basket bar 41. In addition, a plurality of third limiting protrusions 37 can be provided on the connecting plate 34, and the plurality of third limiting protrusions 37 are spaced apart in the front-rear direction. Furthermore, the setting of the third limiting protrusion 37 can also strengthen the structure of the second guide rail 30.

[0083] To prevent the bowl basket 40 from disengaging from the second guide rail 30 forwardly, in one embodiment, a first front stop 381 is further provided on the connecting plate 34. After the bowl basket 40 slides forwardly to the in-place position, it can abut against the rear surface of the first front stop 381, thereby restricting the bowl basket 40 from disengaging from the second guide rail 30 forwardly.

[0084] Similarly, to prevent the bowl basket 40 from disengaging from the second guide rail 30 rearwardly, in one embodiment, a first rear stop 382 is further provided on the connecting plate 34. After the bowl basket 40 slides rearwardly to the in-place position, it can also abut against the front surface of the first rear stop 382, thereby restricting the bowl basket 40 from disengaging from the second guide rail 30 rearwardly.

[0085] In the above embodiments, the multiple bowl basket bars further include a second bowl basket bar 42 extending in the vertical direction. The bowl basket 40 abuts against the first front stopper 381 and the first rear stopper 382 respectively through the second bowl basket bar 42.

[0086] The following specifically introduces the process of pulling out and pushing in the bowl basket 40:

[0087] During the process of pulling out the bowl basket 40, the bowl basket 40 first moves forward relative to the second guide rail 30. When the second bowl basket bar 42 on the bowl basket 40 abuts against the first front stopper 381 on the second guide rail 30, the bowl basket 40 stops moving relative to the second guide rail 30. At this time, when the bowl basket 40 is continuously pulled forward, the second guide rail 30 slides forward relative to the first guide rail 20 until the third front stopper 32 on the second guide rail 30 abuts against the second front stopper 25 on the first guide rail 20.

[0088] During the process of pushing in the bowl basket 40, the bowl basket 40 first moves backward relative to the second guide rail 30. When the second bowl basket bar 42 on the bowl basket 40 abuts against the first rear stopper 382 on the second guide rail 30, the bowl basket 40 stops moving relative to the second guide rail 30. At this time, when the bowl basket 40 is continuously pushed backward, the second guide rail 30 slides backward relative to the first guide rail 20 until the rear surface of the second guide rail 30 abuts against the second rear stopper 26 on the first guide rail 20.

[0089] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
