[0080] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art fall within the scope defined by the claims attached to this application.

[0081] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a central element.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0082] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0083] like Figure 1 As shown, when the bowl basket of the dishwasher contains a large amount of tableware, the slide rail 100 is tilted under the action of the gravity of the bowl basket, and a lateral interaction force is generated between the slide rail roller 300 and the slide rail 100. The slide rail roller 300 cannot roll normally relative to the slide rail 100, and the friction between the slide rail roller 300 and the slide rail 100 changes from rolling friction to sliding friction, thereby greatly increasing the friction force.

[0084] The utility model provides a guide rail mechanism and household appliance, which can effectively improve the smoothness of the guide rail mechanism and effectively reduce the push and pull forces required to be applied at a relatively low cost, thereby improving the user experience.

[0085] Please refer to Figures 2 to 10 , a guide rail mechanism is provided in the embodiment of the present application specification, and the guide rail mechanism may include: a slide rail 1, which is provided with a slide groove 10 extending longitudinally along a first direction; a rolling component 200, wherein the rolling component 200 and the slide groove 10 can move relative to each other, and the rolling component 200 includes a slider 2 cooperating with the slide groove 10 and a plurality of rolling elements arranged on the slider 2, and the plurality of rolling elements are in contact with the slide groove 10; during the relative sliding process between the rolling component 200 and the slide groove 10, the plurality of rolling elements roll relative to the slide groove 10; the slider 2 has a first side 21 provided with a mounting portion 20 and a second side 22 opposite to the first side 21 in the thickness direction, and the slider 2 has a third side 23 and a fourth side 24 opposite to each other in the height direction, the first side 21 is close to the third side 23 as a first force-bearing area 51, and the second side 22 is away from the third side 23 as a second force-bearing area 52, and at least the first force-bearing area 51 and the second force-bearing area 52 are distributed with the rolling elements.

[0086] In the implementation mode of the present application, the existing slide rail roller 300 is improved and replaced with a rolling assembly 200. The rolling assembly 200 includes a slider 2 that cooperates with the slide groove 10 of the slide rail 1 and a plurality of rolling elements arranged on the slider 2. The plurality of rolling elements are distributed in a plurality of force-bearing areas of the slider 2. When the rolling assembly 200 slides relative to the slide groove 10, the plurality of rolling elements roll relative to the slide groove 10, and the sliding friction in the prior art is replaced by the rolling friction, thereby greatly reducing the friction resistance, effectively improving the smoothness of the guide rail mechanism, and effectively reducing the push-pull force required to be applied, thereby improving the user experience.

[0087] like Fig.10 As shown, in some embodiments, the junction of the first side 21 and the third side 23 forms a top corner area 54; the rolling element of the first force area 51 is located in the top corner area 54; the junction of the second side 22 and the fourth side 24 forms a bottom corner area 55; the rolling element of the second force area 52 is located in the bottom corner area 55.

[0088] In this embodiment, when the slide rail 1 is subjected to external force (such as the weight of the bowl basket), its main force-bearing areas include: the top corner area 54 and the bottom corner area 55 located at the diagonal position. In order to prevent the friction form at the diagonal position from becoming sliding friction, rolling elements can be distributed in the top corner area 54 and the bottom corner area 55.

[0089] In some other embodiments, the third side 23 is a third force-bearing area 53 , and the rolling elements are distributed in the third force-bearing area 53 .

[0090] In this embodiment, considering that when the slide rail 1 is subjected to external force (such as the gravity of the bowl basket), the third side 23 of the slider 2 may be subjected to force, in order to prevent sliding friction between the third side 23 and the slide rail 1, a rolling element can be provided in the third force area 53 of the third side 23.

[0091] In this embodiment, the guide rail mechanism mainly includes: a slide rail 1 and a rolling assembly 200 .

[0092] The slide rail 1 may extend longitudinally along the first direction as a whole, and a slide groove 10 may be formed in the slide rail 1 and extend longitudinally along the first direction.

[0093] In order to ensure that the object carried by the rolling assembly 200 can slide smoothly relative to the slide rail 1, the number of groups of the rolling assembly 200 can be multiple, and the multiple groups of rolling assemblies 200 can be arranged at intervals along the first direction. For example, the number of groups of the rolling assembly 200 can be 2 groups, or 3 groups, or more groups. Specifically, the number of groups of the rolling assembly 200 can be different according to the length of the slide rail 1, the specific application scenario of the guide rail mechanism, etc., and the present application does not make a specific limitation here.

[0094] like Figure 2 As shown, specifically, the rolling assembly 200 may include a first rolling assembly and a second rolling assembly, and the first rolling assembly and the second rolling assembly are arranged at intervals along the first direction. In the embodiments and drawings of the present application, the rolling assembly 200 is mainly illustrated by taking two groups as an example. When the rolling assembly 200 includes more groups, it can be adaptively adjusted with reference to the present application.

[0095] The rolling assembly 200 may include a slider 2 matched with the slide groove 10 and a plurality of rolling elements arranged on the slider 2 .

[0096] The outer contour of the slider 2 may be adapted to the structure of the slide 10. Specifically, the outer contour of the slider 2 may be a relatively regular shape, such as a rectangular parallelepiped structure, etc. Of course, the specific structure of the slider 2 is not limited to the present application.

[0097] like Figure 4 As shown, the slider 2 may be provided with a mounting portion 20, and the slider 2 may be positioned and mounted using the mounting portion 20. The slider 2 and the slide rail 1 may move relative to each other, and specifically, one of the slider 2 and the slide rail 1 may be relatively fixed, and the other may move.

[0098] For example, in some embodiments, the mounting portion 20 of the slider 2 is relatively fixed, and the slide rail 1 can move relative to the slider 2 under the action of the driving force along the first direction. Alternatively, in other embodiments, the slide rail 1 is relatively fixed, and the slider 2 can move relative to the slide rail 1 under the action of the driving force along the first direction.

[0099] Specifically, in the specific implementation of the present application, the slider 2 is fixed by the mounting portion 20, and the slide rail 1 moves relative to the slider 2 for explanation. Other implementations can be analogized with reference to this implementation, and the present application will not elaborate on them one by one.

[0100] In this embodiment, the slider 2 has a first side 21 provided with a mounting portion 20 and a second side 22 opposite to the first side 21 in the thickness direction, and the slider 2 has a third side 23 and a fourth side 24 opposite to each other in the height direction. The first side 21 near the third side 23 is a first force-bearing area 51, the second side 22 away from the third side 23 is a second force-bearing area 52, the third side 23 is a third force-bearing area 53, and a plurality of rolling elements are distributed in the first force-bearing area 51, the second force-bearing area 52 and the third force-bearing area 53. The first force-bearing area 51, the second force-bearing area 52 and the third force-bearing area 53 are areas where the rolling assembly 200 is in relative contact with the slide rail 1, wherein the first force-bearing area 51 and the second force-bearing area 52 are areas where the rolling assembly 200 and the slide rail 1 are prone to generate lateral interaction forces under the influence of the weight of the load; the third force-bearing area 53 is an area where the rolling assembly 200 is in contact with the slide rail 1 for rolling cooperation.

[0101] Specifically, the third side 23 is the top side of the slider 2, the fourth side 24 is the bottom side of the slider 2, the slide rail 1 has a top wall corresponding to the top side, a bottom wall corresponding to the bottom side, an opening 11 for passing through the mounting portion 20, and a side wall opposite to the opening 11.

[0102] Among them, the opening 11 can specifically be a longitudinal opening 11 opened along the first direction on the slide rail 1, and the opening 11 is used for the mounting portion 20 of the slider 2 to pass through. When the slide rail 1 moves under the action of the driving force, the rolling element on the slider 2 rolls in the slide groove 10 of the slide rail 1.

[0103] In this embodiment, the rolling element includes any one of the following or a combination thereof: a roller 31, a ball 33. Of course, the specific configuration of the rolling element may be other modes, and is not limited to the above description. A person skilled in the art may make other changes under the guidance of the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they shall be included in the protection scope of this application.

[0104] Please refer to Figure 3 , Figure 4 and Figure 5 In one embodiment, the rolling member may include a roller 31, a roller mounting groove 32 is opened on the slider 2 at the position where the roller 31 is installed, a center hole is set at the center of the roller 31, and the rolling assembly 200 also includes a pin 311, the pin 311 is passed through the center hole and fixed to the roller mounting groove 32, so that the roller 31 can be installed in the roller mounting groove 32.

[0105] In this embodiment, when the rolling element includes a roller 31, a roller mounting groove 32 may be provided on the slider 2 for mounting the roller 31. After the roller 31 is mounted in the roller mounting groove 32 through the pin 311, it can roll relative to the slide rail 1 with the pin 311 as the rotation center. When the roller 31 is mounted in the roller mounting groove 32, at least part of the roller 31 is exposed on the side where the force-bearing area is located, so as to roll with the slide groove 10 of the slide rail 1. For example, for the roller 31 mounted in the first force-bearing area 51, it is at least partially exposed on the first side 21; for the roller 31 mounted in the second force-bearing area 52, it is at least partially exposed on the second side 22; for the roller 31 mounted in the third force-bearing area 53, it is at least partially exposed on the third side 23.

[0106] The center of the roller 31 may be provided with a center hole, and the rolling assembly 200 may further include a pin 311, which may be inserted into the center hole by a clearance fit, and the pin 311 itself is fixed to the roller mounting groove 32 of the slider 2. For example, the slider 2 may be provided with a pin mounting hole on the roller mounting groove 32 for mounting the pin 311. When the slide rail 1 moves along the first direction under the action of an external force, the roller 31 rolls on the slide rail 1, and the roller 31 itself rotates relative to the slider 2 provided with the pin 311.

[0107] Please refer to Figure 6 to Figure 7 In another embodiment, the rolling element includes a ball 33 , and a ball mounting groove 34 is opened on the slider 2 at the position where the ball 33 is installed, and the ball 33 is rotatably arranged in the ball mounting groove 34 .

[0108] In this embodiment, when the rolling element includes a ball 33, a ball installation groove 34 may be provided on the slider 2 for installing the ball 33. Specifically, the structure of the ball installation groove 34 may match the outer contour of the ball 33, and may be a spherical surface. The ball 33 may roll in the ball installation groove 34, and when the slide rail 1 moves along the first direction under the action of an external force, the ball 33 rolls on the slide rail 1, and the ball 33 itself rotates relative to the slider 2.

[0109] Among them, the force borne by the rolling elements in the third force zone 53 is generally greater than that borne by the rolling elements in the first force zone 51 and the second force zone 52. In order to improve the overall service life of the rolling assembly 200, the rolling elements located in the first force zone 51 and the second force zone 52 can be set in the form of balls 33, and the rolling elements located in the third force zone 53 can be set in the form of rollers 31.

[0110] In the embodiment of the present application, for the rolling component 200, the number of rolling elements arranged at the first force-bearing area 51 and the second force-bearing area 52 can be one or more, that is, can be two or more.

[0111] Please refer to Figures 8 to 9 In some embodiments, the first force-bearing area 51 is provided with at least two rolling elements, and the at least two rolling elements are arranged at intervals along the first direction. The second force-bearing area 52 is provided with at least two rolling elements, and the at least two rolling elements are arranged at intervals along the first direction.

[0112] In this embodiment, when multiple rolling elements are arranged in the first force-bearing zone 51, taking the case where two rolling elements are arranged in the first force-bearing zone 51 as an example, the rolling element of the third force-bearing zone 53 can be located in the middle, and the two rolling elements located in the first force-bearing zone 51 can be located on both sides of the rolling element of the third force-bearing zone 53 respectively. Such an arrangement is more conducive to ensuring that when the slide rail 1 moves relative to the rolling assembly 200, the force is more uniform and the movement is smoother.

[0113] When multiple rolling elements are arranged in the second force-bearing zone 52, taking the case where two rolling elements are arranged in the second force-bearing zone 52 as an example, the two rolling elements located in the second force-bearing zone 52 can be respectively located on both sides of the rolling element in the third force-bearing zone 53. Such an arrangement is more conducive to ensuring that when the slide rail 1 moves relative to the rolling assembly 200, the force is more uniform and the movement is smoother.

[0114] A household appliance is also provided in an embodiment of the present application, and the household appliance includes the above-mentioned guide rail mechanism. The household appliance can achieve the technical effect achieved by the guide rail mechanism embodiment by setting the guide rail mechanism.

[0115] Specifically, the household appliance may include any one of the following: a dishwasher, a disinfection cabinet, a drawer, and a curtain.

[0116] Of course, the specific form of the household appliance can also be other forms and is not limited to the above description, that is, the guide rail mechanism can also be used in other forms of household appliances. Technical personnel in the relevant field may make other changes under the inspiration of the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0118] In one embodiment, the inner liner 500 has an open end, and the inner liner 500 also includes a rear side wall opposite to the open end, and a left side wall 501 and a right side wall 502 connected to the rear side wall; a first guide rail mechanism 510 is arranged between the left side wall 501 and the bowl basket 400, and a second guide rail mechanism is arranged between the right side wall 502 and the bowl basket 400, and the first guide rail mechanism 510 and the second guide rail mechanism are arranged opposite to each other.

[0119] In this embodiment, the inner liner 500 may be a box-type inner liner with an open end. Taking the box-type structure of the inner liner 500 as an example, it has an opposite open end and a rear side wall, an opposite left side wall 501 and a right side wall 502, and an opposite top wall and a bottom wall. A guide rail mechanism is provided between the left side wall 501 and the right side wall 502 and the bowl basket 400. The guide rail mechanisms on both sides are arranged oppositely and cooperate with the bowl basket 400 respectively.

Without considering installation errors and manufacturing errors, the first guide rail mechanism 510 and the second guide rail mechanism may be mirror-symmetrical structures.

[0122] Please refer to Figure 4 In one embodiment, a fixing hole 201 is provided in the middle of the mounting portion 20 , and the dishwasher further includes a fixing member, which is passed through the fixing hole 201 to connect the mounting portion 20 to the wall of the inner pot 500 .

[0123] In this embodiment, a mounting portion 20 is provided on one side of the slider 2, and a fixing hole 201 may be provided in the middle of the mounting portion 20. The dishwasher further includes a fixing member, which, after being inserted into the fixing hole 201, can connect the mounting portion 20 to the wall of the inner pot 500, that is, fix the slider 2 to the wall of the inner pot 500. The fixing member may be in the form of a screw, and of course the form of the fixing member is not limited to the above example. In addition, the way the slider 2 is fixed to the wall of the inner pot 500 is not limited to the above connection method. A person skilled in the art may make other changes under the inspiration of the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they shall be covered within the protection scope of this application.

[0124] In one embodiment, the bowl basket 400 may further include a bowl basket roller group, the bowl basket roller group includes at least two bowl basket rollers 401, and the bowl basket rollers 401 are spaced apart along the first direction. When the bowl basket 400 moves relative to the inner liner 500, the bowl basket rollers 401 can roll relative to the slide rail 1.

[0125] In this embodiment, the bowl basket roller assembly can be arranged on both sides of the bowl basket 400, specifically, the side of the bowl basket 400 facing the left side wall 501 of the inner container 500 and the side of the bowl basket 400 facing the right side wall 502 of the inner container 500. Along the first direction, the bowl basket roller assembly can include at least two bowl basket rollers 401 arranged at intervals, so as to ensure that the bowl basket 400 is uniformly stressed as a whole, and moves more smoothly when pushed or pulled relative to the inner container 500.

[0126] The push-pull movement of the bowl basket 400 relative to the inner container 500 can be completed by multiple groups of mechanisms in sections. For example, when the bowl basket 400 is subjected to a pulling force, it can drive the slide rail 1 to move relative to the motion component along the first direction. In addition, the bowl basket 400 itself can also be provided with a bowl basket roller group, which can first roll relative to the slide rail 1. When the bowl basket rolling group moves relative to the slide rail 1 to the limit and no longer moves, the bowl basket roller group can drive the multiple sections of the slide rail 1 to move under the action of the push-pull force.

[0127] Specifically, along the height direction, the bowl basket roller group may include a first bowl basket roller group and a second bowl basket roller group, the slide rail 1 has a top side wall and a bottom side wall opposite to each other along the height direction, the bowl basket roller 401 in the first bowl basket roller group rolls with the top side wall, and the bowl basket roller 401 in the second bowl basket roller group rolls with the bottom side wall. By arranging two groups of upper and lower bowl basket roller groups in the height direction, it can be ensured that the bowl basket 400 moves more smoothly when moving, and the push and pull force required to be applied is effectively reduced.

[0128] Please refer to Figure 2 In one embodiment, the ends of the slide rail 1 are provided with limiting portions 12 for limiting the bowl basket rollers 401 located at both ends.

[0129] In this embodiment, a limiting portion 12 may be provided at the end of the slide rail 1. The limiting portion 12 may be a protrusion formed on the outer surface of the slide rail 1. Specifically, the shape and structure of the limiting portion 12 are not limited in this application. The limiting portion 12 may be used to limit the bowl basket roller 401 to prevent the bowl basket 400 from being separated from the slide rail 1 when the bowl basket 400 is subjected to external push and pull forces.

[0130] Furthermore, the slide rail 1 includes a first slide rail 1 and a second slide rail 1 nested in the first slide rail 1, and the first slide rail 1 and the second slide rail 1 can move relative to each other. When the bowl basket roller 401 located at the opening end closest to the inner liner 500 contacts the limiting portion 12, the second slide rail 1 slides relative to the first slide rail 1 during the pulling process.

[0131] In this embodiment, for the single-sided slide rail 1, it may include a first slide rail 1 and a second slide rail 1 that are nested with each other, and the first slide rail 1 and the second slide rail 1 can move relative to each other. In this embodiment, when the bowl basket 400 is subjected to external tension, under the action of the bowl basket roller 401, the bowl basket 400 first moves relative to the slide rail 1, and when the bowl basket roller 401 located at the outermost side contacts the limit portion 12 on the slide rail 1, under the action of the external tension, the first slide rail 1 and the second slide rail 1 can move relative to each other, so that the bowl basket 400 can be further pulled outward.

[0132] After being applied in a dishwasher, it has been verified that the guide rail mechanism provided in the embodiment of the present application can be realized at a relatively low improvement cost: when the bowl basket 400 is under rated load, the maximum and minimum values ​​of the push and pull forces of the bowl basket 400 are the same and are both controlled at relatively low values.
