The invention provides a guide rail assembly, which is used for a dish washer.
Referring to fig. 1, the dish washer includes a dish washer body including a rack assembly 10, and a liner assembly 20 provided in the rack assembly 10, a bowl basket assembly 30 and a spray arm 50 are provided in the liner assembly 20, a bowl, a dish, a pot wait for a cleaning member to be installed on the bowl basket assembly 30, the spray arm 50 is rotatably connected with the liner assembly 20, and the spray arm 50 is communicated with a water pump (not shown) in the dish washer, the water pump pumps the water into the spray arm 50, and sprays the water from a water spraying hole of the spray arm 50 to clean tableware on the bowl basket assembly 30. The spray arm 50 may be positioned at the bottom, sides, and top of the bowl and basket assembly 30, depending on the configuration of the liner assembly 20 and bowl and basket assembly 30.
Specifically, as shown in fig. 1, the liner assembly 20 can be slidably connected with the bracket assembly 10 of the dishwasher, when the dishwasher is used, the bowl basket assembly 30 is installed in the liner assembly 20, the liner assembly 20 slides into the bracket assembly 10, the liner assembly 20 is sealed, and water is prevented from leaking out of the liner assembly 20 in the process of cleaning a piece to be cleaned on the bowl basket assembly 30 by the spray arm 50. After cleaning, the liner assembly 20 is slid out of the bracket assembly 10 to facilitate removal of the bowl basket assembly 30 from the liner assembly 20 by a user. It should be noted that the number of the liner assemblies 20 of the dishwasher may be one or plural, and when the number of the liner assemblies 20 of the dishwasher is plural, the plural liner assemblies 20 may be arranged in a vertical direction or may be arranged in a lateral direction. For example, in the embodiment shown in fig. 1, the dishwasher includes two liner assemblies 20, and the two liner assemblies 20 are arranged in the up-down direction.
In some embodiments, as shown in fig. 1, the liner assembly 20 is slidably connected to the bracket assembly 10 through a guide rail assembly 40, the guide rail assembly 40 includes a movable rail 41 and a fixed rail structure 42, the movable rail 41 and the fixed rail structure 42 are slidably connected, and the movable rail 41 is used for being connected to the liner assembly 20 to support the liner assembly 20, and the fixed rail structure 42 is used for being connected to the bracket assembly 10 to slidably support the liner assembly 20 on the bracket assembly 10. The movable rail 41 and the fixed rail structure 42 can roll relatively through the rollers, and also can slide relatively directly, and of course, when the movable rail 41 and the fixed rail structure 42 roll relatively through the rollers, a user can pull or push the liner assembly 20 more effort-saving.
Because of the low friction between the movable rail 41 and the rail-fixing structure 42 of the rail assembly 40, when the liner assembly 20 is pulled out from the bracket assembly 10 to mount the bowl basket assembly 30 or the cleaning object into the liner assembly 20, or when the bowl basket assembly 30 or the cleaning object is taken out from the liner assembly 20, the liner assembly 20 may slide relative to the bracket assembly 10 due to the external force, thereby affecting the mounting and dismounting of the bowl basket assembly 30 or the cleaning object.
To avoid the above-mentioned problem, an abutment structure may be provided on the liner assembly 20 and/or the movable rail 41, and a limit structure may be provided on the bracket assembly 20 and/or the fixed rail structure 42, where the limit structure and the abutment structure interfere with each other. When the liner assembly 20 is pulled out of the bracket assembly 10 by a certain distance, the limiting structure can be abutted with the abutting structure to limit the movement of the liner assembly 20 and the movable rail 41 in the direction from the front side to the rear side of the dishwasher.
It will be appreciated that a limit structure may be provided on one of the bracket assembly 20 and the rail-defining structure 42, or both the bracket assembly 20 and the rail-defining structure 42, depending on the structures of the bracket assembly 20 and the rail-defining structure 42; similarly, an abutting structure may be provided on one of the liner assembly 20 and the movable rail 41, or an abutting structure may be provided on both the liner assembly 20 and the movable rail 41, depending on the structures of the liner assembly 20 and the movable rail 41.
It should be noted that, the liner assembly 20 may be limited to a position when being completely pulled out from the bracket assembly 10 by abutting the limiting structure with the abutting structure; the liner assembly 20 can be limited at a position which is moved by a distance along the front side to the rear side of the dish washer by abutting the limiting structure and the abutting structure, and the liner assembly 20 can be specifically determined according to the structure of the liner assembly 20, so that the bowl basket assembly 30 or the piece to be cleaned is not affected when a user loads the bowl basket assembly 30.

The first limiting protrusion 617 may be protruding from an inner side wall of the first clamping groove 616, and the first limiting hole 202 may be formed in an outer side wall of the first clamping portion 201, and the first limiting hole 202 may be a through hole penetrating through the first clamping portion 201 or may be a blind hole. When the first clamping portion 201 is inserted into the first clamping groove 616, the first limiting protrusion 617 is inserted into the corresponding first limiting hole 202, so as to prevent the first clamping portion 201 from being separated from the first clamping groove 616, and improve the connection effect between the first clamping portion 201 and the first clamping groove 616. The number of the first limit protrusions 617 may be one or more, and of course, when the number of the first limit protrusions 617 may be more than one, the anti-falling effect is better.
Further, the first limiting hole 202 may be a through hole, and a first processing hole 614 penetrating through the inner side wall of the first clamping groove 616 is formed, where the first processing hole 614 is opposite to the free end of the first limiting protrusion 617, so as to facilitate processing the first limiting protrusion 617 on the inner side wall of the first clamping groove 616. In addition, the first limit protrusion 617 may be pushed through the first machined hole 614 to disengage the first limit protrusion 617 from the first limit hole 202, thereby facilitating removal of the coupling 61 '"from the liner assembly 20 for replacement of the damaged coupling 61'".
In addition, a guiding slope may be disposed on the free end of the first limit protrusion 617, where the guiding slope is located on a side of the free end of the first limit protrusion 617 facing the notch of the first clamping groove 616, and during the process of inserting the first clamping portion 201 into the first clamping groove 616, the guiding slope abuts against the first clamping portion 201 to deform the first clamping portion 201 and/or deform the first limit protrusion 617, so that the first limit protrusion 617 passes over the first clamping portion 201 and is inserted into the first limit hole 202 on the first clamping portion 201.
In this embodiment, the first clamping portion 201 may be located on the liner outer frame 22 and configured in a plate shape, so that the width of the first clamping groove 616 is equivalent to the width of the first clamping portion 201, so that the fit between the first clamping portion 201 and the first clamping groove 616 is more stable. The first holding portion 201 may be located at the bottom of the liner outer frame 22, or the first holding portion 201 may be located at a side surface of the liner outer frame 22, and may be specifically determined according to a position of the limiting structure. For example: when the limit structure is located on the guide rail assembly 40 and the guide rail assembly 40 is located at the bottom of the liner outer frame 22, the first clamping portion 201 may be located at the bottom of the liner outer frame 22, so that the first connecting piece 61' "is closer to the limit structure; when the limiting structure is located on the bracket assembly 10, the first clamping portion 201 may be located on a side surface of the liner outer frame 22, so that the abutment 61' "is closer to the limiting structure.
Of course, the second clamping portion may be provided on the side of the abutment 61 '"facing the liner assembly 20 in a protruding manner, and the liner assembly 20 may be provided with a second clamping groove, and when the abutment 61'" is connected to the liner assembly 20, the second clamping portion may be inserted into the second clamping groove and clamped to the second clamping groove to connect the abutment and the liner assembly.
Likewise, in order to prevent the second clamping portion from falling out of the second clamping groove, a second limiting protrusion may be convexly arranged on an inner side wall of the second clamping groove, a second limiting hole is formed in an outer side wall of the second clamping portion, and when the second clamping portion is inserted into the second clamping groove, the second limiting protrusion is inserted into the second limiting hole, which is not described herein.
Further, for convenient processing of the second spacing protrusion, the second spacing hole may be a through hole, and a second processing hole penetrating through is provided on the inner side wall of the second clamping groove, and the second processing hole is opposite to the free end of the second spacing protrusion.
In addition, in order to improve the connection stability of the second clamping groove and the second clamping portion, the second clamping groove may be formed on the liner outer frame 22, so that the second clamping portion is formed in a plate shape, and the width of the second clamping groove is equal to the thickness of the second clamping portion, which is not described herein.
It should be noted that, the connecting member 61' and the liner assembly 20 may be connected by one of the two connection methods, or may be connected by both of the two connection methods.
The manner of connecting the abutting piece and the movable rail 41 may be used for the manner of connecting the abutting piece and the liner assembly 20. The manner of connecting the abutting piece and the liner assembly 20 described above may also be used for connecting the abutting piece and the movable rail 41.
In this embodiment, when the second abutting portion of the limiting structure has no elasticity. For example, as shown in fig. 3, the limiting structure may be arranged in a column shape, a block shape, or the like, where the limiting structure may be fixed between the limiting structure and the bracket assembly 10 and/or the rail fixing structure 42 by means of fastening, adhering, welding, or the like, or may be formed by forming a fastening hole on the bracket assembly 10 and/or the rail fixing structure 42, and inserting the limiting structure into the fastening hole and fastening the limiting structure with the fastening hole, so that the installation of the limiting structure is more convenient.
In this embodiment, the method of making the second contact portion elastic is similar to the method of making the first contact portion elastic.
In some embodiments, the limiting structure may include a limiting member having a second abutting portion abutting against the abutting structure, the second abutting portion being made of an elastic material such as plastic, steel, or the like, so that the second abutting portion is elastic. For example, as shown in fig. 18 and 19, the second contact portion 711 of the stopper 71″ may be formed in a sheet shape, so that the second contact portion 711 has better elasticity, occupies smaller space, and is more convenient to process. Naturally, the stopper may have a block-like or columnar structure having elasticity.
In other embodiments, as shown in fig. 5 to 7, the limiting structure may further include a second mounting seat 73 and a limiting member 71' abutted to the connecting member 61', where the second mounting seat 73 and the limiting member 71' are elastically connected by a second elastic member 74. Further, the second mounting seat 73 may be provided with a second chute 731, the stopper 71' is slidably mounted in the second chute 731, the second elastic member 74 is disposed between the bottom of the second chute 731 and the stopper 71', and one end of the second elastic member 74 abuts against the bottom of the second chute 731, and the other end abuts against the stopper 71 '. The specific connection manner between the second mounting seat 73 and the limiting member 71' may refer to the connection manner between the first mounting seat 63 and the connecting member 61″ described above, and will not be described herein.
The second mounting seat 73 may be connected to the bracket assembly 10 and/or the rail-fixing structure 42 through a connecting member, or may be directly connected to the bracket assembly 10 and/or the rail-fixing structure 42. In a preferred embodiment, as shown in fig. 6, a second clamping hole 426 may be formed on the rail fixing structure 42, and the second mounting seat 73 is installed in the second clamping hole 426 and is in clamping connection with the second clamping hole 426.
On the basis of any of the above embodiments, as shown in fig. 4, the abutment structure has a first guide surface 66 and a first stopper surface for abutting against the stopper structure, the first guide surface 66 and the first stopper surface being inclined with respect to the front-rear direction of the dishwasher and distributed in the front-rear direction of the dishwasher, and when the liner assembly 20 is pulled out from the rack assembly 10 in the direction from the rear side to the front side of the dishwasher, the first guide surface 66 abuts against the stopper structure to guide the abutment structure beyond the stopper structure. The abutting structure can pass through the limiting structure by elastic deformation of the limiting structure, and can pass through the limiting structure by elastic deformation of the abutting structure. When the liner assembly 20 is pushed into the rack assembly 10 in a front-to-rear direction of the dishwasher, the stopper structure abuts against the first stopper surface to restrict the liner assembly 10 and the movable rail 41 from sliding in the front-to-rear direction of the dishwasher.
Wherein the direction in which the first guide surface 66 and the first limit surface are inclined with respect to the front-rear direction of the dishwasher may be determined according to the manner in which the abutment structure passes over the limit structure. For example: when the abutting structure passes over the limiting structure from the upper side of the limiting structure, the first guide surface 66 and the first limiting surface can be upwards inclined relative to the front-back direction of the dish washer; when the abutting structure passes over the limiting structure from the lower part of the limiting structure, the first guide surface 66 and the first limiting surface can be obliquely arranged downwards relative to the front-back direction of the dish washer, and when the abutting structure passes over the limiting structure from the side edge of the limiting structure, the first guide surface 66 and the first limiting surface can be obliquely arranged transversely relative to the front-back direction of the dish washer.
The angle of the first guiding surface 66 inclined relative to the front-rear direction of the dishwasher is α, and the angle of the first limiting surface inclined relative to the front-rear direction of the dishwasher is β, so that β > α can be made, so that the limiting structure has a good limiting effect on the abutting structure, and the liner assembly 20 is smoothly pulled out from the bracket assembly 10. Wherein the angle of α and β may depend on the configuration of the abutment structure, and in a preferred embodiment 20 β 90 may be used. Further, 30 DEG.ltoreq.alpha < beta.ltoreq.60 DEG may be made.
Similarly, as shown in fig. 19, the abutment structure may have a second guide surface 76 and a second stopper surface 77, the second stopper surface 77 and the second guide surface 76 may be inclined with respect to the front-rear direction of the dishwasher and may be distributed in the front-rear direction of the dishwasher, and when the liner assembly 20 is pulled out from the rack assembly 10 in the direction from the rear side to the front side of the dishwasher, the second guide surface 76 may abut against the abutment structure to guide the abutment structure beyond the stopper structure. When the liner assembly 20 is pushed into the rack assembly 10 in a front-to-rear direction of the dishwasher, the second limiting surface 77 abuts the abutment structure to limit the liner assembly 10 and the movable rail 41 from sliding in the front-to-rear direction of the dishwasher.
The angle of inclination of the second guiding surface 76 with respect to the front-rear direction of the dishwasher is θ, and the angle of inclination of the second limiting surface with respect to the front-rear direction of the dishwasher is γ, so that γ > θ can be made, so that the limiting structure has a good limiting effect on the abutting structure, and the liner assembly 20 is smoothly pulled out from the bracket assembly 10. Wherein the angles of y and θ may depend on the configuration of the abutment structure, and in a preferred embodiment 20 θ < γ 90 may be used. Further, θ may be made 30.ltoreq.θ < γ.ltoreq.60 °.
On the basis of any of the above embodiments, as shown in fig. 2 and 12, the movable rail 41, the rail fixing structure 42 and the liner assembly 20 each have front and rear ends distributed in the front-rear direction of the dishwasher, and the rack assembly 10 has front and rear sides distributed in the front-rear direction of the dishwasher. When the abutting structure is provided on the movable rail 41, the abutting structure may be provided at the rear end of the movable rail 41; alternatively, when the abutment structure is disposed on the liner assembly 20, the abutment structure may be disposed at the rear end of the liner assembly 20, so that the abutment structure is limited by the limiting structure when the liner assembly 20 is pulled out from the bracket assembly 10.
Of course, when the limit structure is disposed on the rail fixing structure 42, the limit structure may be disposed at the front end of the rail fixing structure 42; or, when the limiting structure is disposed on the bracket assembly 10, the limiting structure may be disposed on the front side of the bracket assembly 10, so that the abutment structure is limited by the limiting structure when the liner assembly 20 is pulled out from the bracket assembly 10.
In a preferred embodiment, the abutting structure may be disposed at the rear end of the movable rail 41 or the liner assembly 20, and the limiting structure may be disposed at the front end of the fixed rail structure 42 or at the front side of the bracket assembly 10, so that the liner assembly 20 is limited to a position when it is completely pulled out from the bracket assembly 10.

Therefore, the problem that the sliding between the fixed rail 422 and the movable rail structure 41 is not smooth due to the fact that the fixed rail 422 deforms under the action of gravity of the bowl basket assembly 30 and the liner assembly 20 after the fixed rail 422 is directly connected with the bracket assembly 10 can be avoided. The rail 422 and the rail support 423 may be connected by welding, fastening, screws, etc., which is not limited in this embodiment.
In this embodiment, when the limiting structure is disposed on the rail fixing structure 42, the limiting structure may be disposed on the rail fixing frame 422, or the limiting structure may be disposed on the rail fixing frame 423, which will not affect the accuracy of the rail fixing frame 422 when the limiting structure is disposed on the rail fixing frame 423, thereby enabling the sliding of the movable rail 42 relative to the rail fixing frame 422 to be smoother.
Further, the rail fixing bracket 423 has a supporting portion 424 for supporting the rail fixing 422, and a mounting portion 425 for mounting with the bracket assembly 10, and the limiting structure may be disposed on a side of the supporting portion 424 facing the abutment structure, or may be disposed on a side of the mounting portion 425 facing the abutment structure, specifically depending on the structure of the rail fixing bracket 423.
As shown in fig. 1 and 12, the liner assembly 20 includes a liner body 21 and a liner outer frame 22, and the liner assembly 21 is mounted in the liner outer frame 22. In this embodiment, when the abutting structure is connected to the liner assembly 20, the abutting structure may be connected to the liner body 21 or the liner outer frame 22, and of course, when the abutting structure is connected to the liner outer frame 22, the liner body 21 is deformed due to the processing of the connecting portion of the liner body 21 and the abutting structure, which results in water leakage of the liner body 21, can be avoided.
In this embodiment, when the abutting structure and the movable rail 41 are connected, the first abutting portion of the abutting structure may be located at the top of the movable rail 41, at one side in the width direction of the movable rail 41. In a preferred embodiment, as shown in fig. 2, a limiting structure may be positioned on one side of the movable rail 41 near the rack assembly 20 to fully utilize the gap between the movable rail 41 and the rack assembly 10 and improve the space utilization of the dishwasher. When the limiting structure is disposed on the rail fixing structure 42, the limiting structure may be located on the supporting portion 424 of the rail fixing structure 42 and on a side of the movable rail 41 near the bracket assembly 10.
