[0002] With the development of society and the advancement of science and technology, people's requirements for life are getting higher and higher. More and more families are starting to install and use dishwashers. Dishwashers not only bring convenience to people, but also save people's time.

[0003] Currently, many dishwashers have a double-layer structure. The upper pull-out basket can be pushed and pulled into the inner tank. Two left and right guide rails and two sets of guide rollers are set at the corresponding positions of the inner tank. Two sets of left and right pull-out basket rollers are set at the corresponding positions of the pull-out basket. The pull-out basket rollers are mounted on the guide rails, and the guide rails are mounted on the guide rollers. When the pull-out basket is pushed and pulled, the pull-out basket rollers can slide along the guide rails, and the guide rails can slide along the guide rollers. For details, please refer to the Chinese patent application number CN202321282460.9, "A Guide Rail Structure for Household Appliances and Household Appliances." In addition, in some solutions, the guide rollers are replaced by internal guide rails. For details, please refer to the Chinese patent application number CN201821643957.8, "Guide Rail Assembly and Dishwasher."

[0004] However, in the above solution, when the roller slides to the extreme position along the outer guide rail, it will collide with the stopper outside the outer guide rail. When the outer guide rail slides to the extreme position along the inner guide rail, the stopper inside it will collide with the inner guide rail, thereby generating a collision sound and affecting the customer experience. Utility Model Content

[0005] The first technical problem to be solved by the present invention is to provide a guide rail structure for a pull-out basket cabinet that can reduce collision noise in response to the current status of the existing technology.

[0006] The second technical problem to be solved by the present invention is to provide a pull-out basket cabinet using the above-mentioned guide rail structure.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a guide rail structure for a pull-out basket cabinet, comprising

[0008] A moving guide rail extending in a front-to-rear direction;

[0009] A first guide member is provided in the movable guide rail and cooperates with the movable guide rail;

[0010] A second guide member is provided outside the movable guide rail and cooperates with the movable guide rail;

[0011] a first limit seat, provided at the front end of the movable guide rail, having a first stopper located inside the movable guide rail and a second stopper located outside the movable guide rail, wherein the first stopper and the second stopper are respectively used to limit the forward movement limit positions of the first guide member and the second guide member; and

[0012] a second limit seat, provided at the rear end of the movable guide rail, having a third stopper located inside the movable guide rail and a fourth stopper located outside the movable guide rail, the third stopper and the fourth stopper being used to limit the rearward movement of the first guide member and the second guide member, respectively;

[0013] The feature is that the outer periphery of at least two of the first stopper, the second stopper, the third stopper and the fourth stopper is provided with a flexible sleeve.

[0014] Preferably, the outer peripheries of the first stopper, the second stopper, the third stopper and the fourth stopper are all covered with flexible sleeves, which are respectively referred to as the first flexible sleeve, the second flexible sleeve, the third flexible sleeve and the fourth flexible sleeve.

[0015] In order to better transmit the thrust to the entire first flexible sleeve, the middle area of the rear side wall of the first flexible sleeve is higher than the peripheral area.

[0016] In order to evenly transmit the thrust, the peripheral area of the rear side wall of the first flexible sleeve gradually decreases from the middle to the outer edge.

[0017] In order to absorb collision energy, the first limit seat has elastic ribs located inside the moving guide rail. When the first guide member moves forward to the extreme position relative to the moving guide rail, the front end of the first guide member contacts the first flexible sleeve and the elastic ribs at the same time.

[0018] In order to facilitate deformation of the elastic rib during a collision, at least a portion of the elastic rib gradually approaches the first stopper from front to back.

[0019] In order to evenly absorb collision energy, there are two elastic ribs, which are respectively located directly above and directly below the first stopper.

[0020] In order to achieve guiding cooperation between the first guide member and the movable guide rail, the first guide member is a fixed guide rail extending in the front-to-back direction, and the movable guide rail can be slidably mounted on the outer periphery of the fixed guide rail. When the movable guide rail moves backward to the extreme position relative to the fixed guide rail, the first flexible sleeve contacts the front end of the fixed guide rail, and when the movable guide rail moves forward to the extreme position relative to the fixed guide rail, the third flexible sleeve contacts the rear end of the fixed guide rail.

[0021] In order to achieve guiding cooperation between the second guide member and the movable guide rail, the second guide member includes at least two first rollers arranged above the movable guide rail in the front-to-back direction, and each of the first rollers is in frictional contact with the top wall of the movable guide rail. When the second guide member moves forward to the extreme position relative to the movable guide rail, the first roller located at the front contacts the second flexible sleeve. When the second guide member moves backward to the extreme position relative to the movable guide rail, the first roller located at the rear contacts the fourth flexible sleeve.

[0022] In order to achieve guiding stability of the second guide member and the movable guide rail, the second guide member further includes at least one second roller arranged below the movable guide rail, and the second roller is in friction contact with the bottom wall of the movable guide rail.

[0023] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a pull-out basket cabinet, characterized in that it includes a cabinet body, a pull-out basket and the above-mentioned guide rail structure, the number of the guide rail structures is two groups, and they are symmetrically arranged on the left and right sides of the pull-out basket, the first guide member of each guide rail structure is installed on the side wall inside the cabinet body, and the second guide member of each guide rail structure is installed on the side of the pull-out basket.

[0024] Compared with the prior art, the advantage of the present invention is that by arranging a flexible sleeve on the outer periphery of at least two of the first stopper, the second stopper, the third stopper and the fourth stopper, when the movable guide rail collides with the first guide member and the second guide member, it is not a rigid head-on collision, and the flexible sleeve can act as a buffer to reduce the collision sound.

[0029] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0030] In the specification and claims of the present invention, directional terms such as "front," "back," "up," "down," "left," "right," "side," "top," and "bottom" are used to describe various exemplary structural parts and components of the present invention. However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different orientations, these directional terms are intended for illustrative purposes only and should not be construed as limiting. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0031] like Figures 1 to 4 The figure shows a preferred embodiment of the pull-out basket cabinet of the present invention. The pull-out basket cabinet can be a cabinet, a cabinet dishwasher, etc. This embodiment uses a cabinet dishwasher as an example. The pull-out basket cabinet includes a cabinet body 1, a pull-out basket 2, and a guide rail structure 3.

[0032] The front side of the cabinet body 1 is open.

[0033] The pull-out basket 2 can be pushed and pulled forward and backward through the opening on the front side of the cabinet body 1 to enter and exit the inner cavity of the cabinet body 1 .

[0034] There are two sets of guide rail structures 3, symmetrically arranged on the left and right sides of the pull-out basket 2. Each guide rail structure 3 is connected between the cabinet 1 and the pull-out basket 2, and includes a fixed guide rail 32, a movable guide rail 31, a first roller 33a, a second roller 33b, a first limit seat 34, and a second limit seat 35.

[0035] Specifically, the fixed guide rail 32 is arranged on the side wall inside the cabinet 1 along the front-to-back direction;

[0036] The cross section of the movable guide rail 31 is C-shaped. The movable guide rail 31 extends in the front-to-back direction and is slidably mounted on the outer periphery of the fixed guide rail 32 to achieve guiding cooperation with the fixed guide rail 32.

[0037] The first roller 33a and the second roller 33b are both rotatably connected to the side of the pull-out basket 2; there are two first rollers 33a, which are spaced apart in the front-to-back direction above the movable guide rail 31, and each first roller 33a is in frictional contact with the top wall of the movable guide rail 31; there is one second roller 33b, which is arranged below the movable guide rail 31, and is in frictional contact with the bottom wall of the movable guide rail 31, thereby cooperating with the first roller 33a to achieve guiding cooperation with the movable guide rail 31;

[0038] The first limit seat 34 is inserted into the front end of the movable guide rail 31, and the first limit seat 34 has a first stopper 341, a second stopper 342 and an elastic rib 343; the first stopper 341 extends into the movable guide rail 31, and a first flexible sleeve 3411 is sleeved on its outer periphery. The middle area of the rear side wall of the first flexible sleeve 3411 is higher than the outer periphery, and the outer periphery of the rear side wall of the first flexible sleeve 3411 gradually decreases from the middle to the outer edge; the second stopper 342 extends outward from the top wall of the movable guide rail 31, and a second flexible sleeve 3421 is sleeved on its outer periphery; there are two elastic ribs 343, which are respectively located directly above and directly below the first stopper 341, and the rear half of each elastic rib 343 gradually approaches the above-mentioned first stopper 341 from front to back;

[0039] The second limit seat 35 is inserted into the rear end of the movable guide rail 31, and the second limit seat 35 has a third stopper 351 and a fourth stopper 352; the third stopper 351 extends into the movable guide rail 31, and a third flexible sleeve 3511 is sleeved around its periphery; the fourth stopper 352 extends outward from the top wall of the movable guide rail 31, and a fourth flexible sleeve 3521 is sleeved around its periphery.

[0040] When the movable guide rail 31 moves backward to the limit position relative to the fixed guide rail 32 on the cabinet 1, it means that the fixed guide rail 32 moves forward to the limit position relative to the movable guide rail 31. At this time, the first flexible sleeve 3411 and the elastic rib 343 simultaneously contact the front end of the fixed guide rail 32. When the movable guide rail 31 moves forward to the limit position relative to the fixed guide rail 32 on the cabinet 1, it means that the fixed guide rail 32 moves backward to the limit position relative to the movable guide rail 31. At this time, the third flexible sleeve 3511 contacts the rear end of the fixed guide rail 32.

[0041] When the roller moves forward to the extreme position relative to the movable guide rail 31 with the pull-out basket 2, the first roller 33a located at the front contacts the second flexible sleeve 3421; when the roller moves backward to the extreme position relative to the movable guide rail 31 with the pull-out basket 2, the first roller 33a located at the back contacts the fourth flexible sleeve 3521.

[0042] The working principle of this embodiment is as follows: when the pull-out basket 2 is pulled out, the roller rolls forward along the movable guide rail 31 until the first roller 33a at the front contacts the second flexible sleeve 3421. At this time, continuing to pull the pull-out basket 2 outward will drive the movable guide rail 31 to slide forward along the fixed guide rail 32 until the third flexible sleeve 3511 contacts the rear end of the fixed guide rail 32. At this time, the pull-out basket 2 moves forward to the limit state; when the pull-out basket 2 is pushed in, the roller rolls backward along the movable guide rail 31 until the first roller 33a at the rear contacts the fourth flexible sleeve 3521. At this time, continuing to push the pull-out basket 2 inward will drive the movable guide rail 31 to slide backward along the fixed guide rail 32 until the first flexible sleeve 3411 and the elastic rib 343 contact the front end of the fixed guide rail 32 at the same time. At this time, the pull-out basket 2 moves backward to the limit state.

[0043] Due to the setting of the flexible sleeve, when a collision occurs, it is not a rigid head-on collision. The flexible sleeve can play a buffering role to reduce the collision sound. In addition, when the pull-out basket 2 moves backward to the extreme state, the fixed guide rail 32 first contacts the middle area of the rear side wall of the first flexible sleeve 3411, so as to better transmit the thrust to the entire first flexible sleeve 3411. At the same time, due to the design of the elastic rib 343, when it contacts the fixed guide rail 32, the elastic rib 343 deforms to absorb the collision energy, that is, the collision energy is converted into the deformation of the elastic rib 343, thereby reducing the collision sound.
