Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a chassis and a dishwasher. Background Technology

[0002] With social development and the improvement of people's living standards, dishwashers are being used more and more widely in daily life. Dishwashers can automatically clean dishes, making life more convenient.

[0003] Dishwashers typically consist of an inner tub and a chassis located below the inner tub to support it. The bottom of the inner tub usually has many uneven protrusions. When the dishwasher vibrates, the chassis is easily impacted by these protrusions, causing it to deform. Utility Model Content

[0004] This application provides a chassis and a dishwasher, in which the bottom surface of the inner tank is separated from the bearing surface by a partition pad, which can prevent the protruding structure of the bottom surface of the inner tank from impacting the bearing surface and causing the chassis to deform.

[0005] In a first aspect, this application provides a chassis for being disposed below the inner tub of a dishwasher and for supporting the inner tub, the chassis comprising:

[0006] A tray body, the tray body including a base plate and peripheral side plates, the peripheral side plates extending along the periphery of the base plate and connected to the base plate, the peripheral side plates including a first side plate, the first side plate having a bearing surface for supporting the inner liner, the bearing surface extending along the length direction of the first side plate; and,

[0007] A partition pad is disposed on the bearing surface. The partition pad is used to place the inner liner and contact the bottom surface of the inner liner to separate the bottom surface of the inner liner from the bearing surface.

[0008] In some embodiments, the partition pad is a soft pad. The soft pad has a certain cushioning and shock absorption capacity, which can reduce the impact force transmitted from the inner tub to the bearing surface when the dishwasher vibrates, thereby preventing the bearing surface from being subjected to excessive impact force and causing the chassis to deform. In addition, the soft pad can deform in a way that can cover and fill the protruding structure on the bottom surface of the inner tub that contacts the soft pad, thereby making the contact between the soft pad and the inner tub tighter and preventing the soft pad from separating from the inner tub.

[0009] In some embodiments, the partition pad is an elastic cushioning pad. The elastic cushioning pad has the ability to deform elastically, which can provide better cushioning and shock absorption for the base while ensuring sufficient clearance between the bottom surface of the inner liner and the bearing surface.

[0010] In some embodiments, the thickness of the partition pad is h, where 8 mm ≤ h ≤ 12 mm. This ensures sufficient clearance between the bottom surface of the inner tub and the supporting surface, preventing the inner tub from being raised too high by the partition pad, which would significantly increase the size of the dishwasher.

[0011] In some embodiments, the first side plate includes: a first plate body, the upper surface of which is the bearing surface; a second plate body, located between the first plate body and the bottom plate, and connected to both the bottom plate and the first plate body; and a third plate body, located above the first plate body and connected to it, forming a stepped structure with the first plate body and the second plate body. The third plate body can limit the movement of the inner liner, preventing it from sliding horizontally away from the receiving cavity.

[0012] In some embodiments, the peripheral side plate further includes two second side plates disposed adjacent to the first side plate, the two second side plates being disposed opposite to each other and connected to the bottom plate; wherein, the two second side plates are respectively connected to both ends of the first side plate to form a limiting groove with the first side plate, the bearing surface forming the bottom wall surface of the limiting groove, and the partition pad located in the limiting groove. When the inner liner is placed on the chassis, part of the inner liner is located in the limiting groove, and the limiting groove can limit the inner liner, preventing the inner liner from moving towards the third plate and the second side plate.

[0013] In some embodiments, the second side plate includes: a first portion connected to the first side plate to form the limiting groove with the first side plate; and a second portion located on the side of the first portion away from the first side plate and connected to the first portion and the bottom plate, wherein the top surface of the second portion is lower than the bearing surface. This can reduce the contact area between the chassis and the inner tub, thereby preventing the second portion from deforming due to impact from the protruding structure at the bottom of the inner tub when the dishwasher vibrates.

[0014] In some embodiments, the chassis further includes: a third side plate, disposed opposite to the first side plate and connected to the base plate, the top surface of the third side plate being lower than the bearing surface; and a connecting assembly, disposed opposite to the first side plate, the connecting assembly being used to connect the chassis and the inner tub. This can reduce the contact area between the chassis and the inner tub, thereby preventing the protruding structure at the bottom of the inner tub from impacting the third side plate and causing deformation of the third side plate when the dishwasher vibrates.

[0015] In some embodiments, the distance between the connecting component and the first side plate is greater than the distance between the connecting component and the third side plate. This can provide better support for the second side of the bottom surface of the inner liner, preventing the inner liner from tilting.

[0016] Secondly, this application also provides a dishwasher, including an inner tub and a chassis as described in any of the above embodiments, wherein the inner tub is located above the chassis, a portion of the bottom surface of the inner tub is placed on and in contact with the partition pad, and the bottom surface of the inner tub is spaced apart from the bearing surface.

[0017] The beneficial effects of this application are as follows: by separating the bottom surface of the inner tub from the bearing surface by the partition pad, a buffer gap is formed between the bottom surface of the inner tub and the bearing surface. When the dishwasher vibrates, the raised structure of the bottom surface of the inner tub is less likely to come into contact with the bearing surface, thereby preventing the raised structure of the bottom surface of the inner tub from impacting the bearing surface and causing the chassis to deform.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] This application provides a chassis and a dishwasher to solve the problem that the bottom of the inner tub of a dishwasher in the related art usually has many uneven protrusions, and when the dishwasher vibrates, the chassis is easily deformed by the impact of these protrusions.

[0027] Firstly, this application provides a chassis 10, such as Figure 1 As shown, the chassis 10 is used to mount the inner tub 60 of the dishwasher (e.g., Figure 3 Below the inner liner 60, the chassis 10 includes the disc body 20 and the partition pad 30.

[0028] The disc body 20 is the main structure of the chassis 10. The disc body 20 is used to provide support and installation space for the inner liner 60. The disc body 20 can be roughly cylindrical, square, or other shapes. The disc body 20 includes a base plate 21 and a peripheral side plate 22. The peripheral side plate 22 extends along the periphery of the base plate 21 and is connected to the base plate 21. The peripheral side plate 22 includes a first side plate 221. The first side plate 221 has a bearing surface 221a for bearing the inner liner 60. The bearing surface 221a extends along the length direction of the first side plate 21. The peripheral side plate 22 can be formed with the base plate 21 to form a receiving cavity with a top opening. The first side plate 221 is one of the multiple side plates of the peripheral side plate 22. The bottom of the inner liner 60 can be inserted into the receiving cavity through the opening and supported by the bearing surface 221a. The partition pad 30 is disposed on the bearing surface 221a. The partition pad 30 is used to place the inner liner 60 and contact the bottom surface of the inner liner 60 to separate the bottom surface of the inner liner 60 from the bearing surface 221a. The partition pad 30 can be fixed to the bearing surface 221a by means of double-sided adhesive, plastic adhesive, snap-fit, clip-fit, threaded fastener, tenon and mortise connection or welding.

[0029] It is understood that in this application, the bottom surface of the inner tub 60 is separated from the bearing surface 221a by the partition pad 30, so that there is a buffer gap between the bottom surface of the inner tub 60 and the bearing surface 221a. When the dishwasher vibrates, the protruding structure on the bottom surface of the inner tub 60 is not likely to come into contact with the bearing surface 221a, thereby preventing the protruding structure on the bottom surface of the inner tub 60 from impacting the bearing surface 221a and causing the chassis 10 to deform.

[0030] In some embodiments, the partition pad 30 is a soft pad with a certain cushioning and shock absorption capacity, which can reduce the impact force transmitted from the inner tub 60 to the bearing surface 221a when the dishwasher vibrates, thereby preventing the bearing surface 221a from being deformed due to excessive impact force. In addition, the soft pad can deform and cover and fill the protruding structure on the bottom surface of the inner tub 60 that contacts the soft pad, thereby making the soft pad and the inner tub 60 more tightly connected and preventing the soft pad from separating from the inner tub 60. The partition pad 30 can be made of materials such as pearl cotton, foam board, nitrile rubber, latex, synthetic rubber, synthetic resin, foamed polypropylene, rubber and plastic products made of ethylene and vinyl acetate copolymer, corrugated cardboard, honeycomb cardboard, air cushion plastic film, spring, paper fiber molding material, polyurethane foam or sponge, etc.

[0031] Furthermore, the partition pad 30 is an elastic buffer pad, which has the ability to deform elastically. It can provide better cushioning and shock absorption for the base while ensuring sufficient gap between the bottom surface of the inner liner 60 and the bearing surface 221a.

[0032] In some embodiments, the thickness of the partition pad 30 is h, where 8 mm ≤ h ≤ 12 mm. It is understood that when h is less than 8 mm, the thickness of the partition pad 30 is too small, failing to guarantee sufficient clearance between the bottom surface of the inner tub 60 and the supporting surface 221a. When the dishwasher vibrates, the raised structure on the bottom surface of the inner tub 60 easily contacts the supporting surface 221a. When h is greater than 12 mm, the thickness of the partition pad 30 is too large, causing the inner tub 60 to be lifted too high, resulting in a significantly larger dishwasher volume and a shorter length of the portion of the inner tub 60 inserted into the receiving cavity, making it easier for the inner tub 60 to detach from the receiving cavity. Here, h can be 8 mm, 8.5 mm, 9 mm, 10 mm, 11 mm, 12 mm, or other values.

[0033] See also Figure 1 As shown, in some embodiments of this application, the first side plate 221 includes a first plate body 221b, a second plate body 221c, and a third plate body 221d.

[0034] The upper surface of the first plate 221b is the bearing surface 221a; the second plate 221c is located between the first plate 221b and the base plate 21, and is connected to both the base plate 21 and the first plate 221b; the third plate 221d is located above the first plate 221b and is connected to the first plate 221b, forming a stepped structure with the first plate 221b and the second plate 221c. It can be understood that the first plate 221b supports the inner liner 60, and the second plate 221c connects the first plate 221b to the base plate 21 and provides support for the second plate 221c. When the inner liner 60 is placed on the chassis 10, a portion of the inner liner 60 is located within the space defined by the stepped structure (e.g., ...). Figure 3 In the process, the inner liner 60 can be limited by the third plate 221d to prevent the inner liner 60 from sliding horizontally away from the receiving cavity.

[0035] The bearing surface 221a can be parallel to the horizontal plane, thus providing more stable support for the inner liner 60. The first plate 221b and the third plate 221d can be perpendicular to the second plate 221c, or form an angle of 30 degrees, 45 degrees, 60 degrees, 75 degrees, 120 degrees, or other angles other than 90 degrees. The first plate 221b, the second plate 221c, and the third plate 221d can be integrally formed to improve the connection strength between the second plate 221c and the first plate 221b and the third plate 221d. Of course, according to actual needs, the first plate 221b, the second plate 221c, and the third plate 221d can also be formed separately and then spliced ​​by welding, gluing, snap-fitting, threaded connection, or other methods.

[0036] In some embodiments, the peripheral side plate 22 further includes two second side plates 222 disposed adjacent to the first side plate 221. The two second side plates 222 are disposed opposite to each other and connected to the bottom plate 21. The two second side plates 222 are respectively connected to both ends of the first side plate 221 to form a limiting groove 224 with the first side plate 221. The bearing surface 221a forms the bottom wall surface of the limiting groove 224, and the partition pad 30 is located in the limiting groove 224. It can be understood that when the inner liner 60 is placed on the chassis 10, part of the inner liner 60 is located in the limiting groove 224. The limiting groove 224 can limit the inner liner 60 and prevent the inner liner 60 from moving towards the third plate 221d and the second side plate 222.

[0037] The second side plate 222 may include a first part 222a and a second part 222b. The first part 222a is connected to the first side plate 221 to form a limiting groove 224 with the first side plate 221. The second part 222b is located on the side of the first part 222a away from the first side plate 221 and is connected to the first part 222a and the bottom plate 21. The top surface of the second part 222b is lower than the bearing surface 221a, so that when the bearing surface 221a supports the inner liner 60, the second part 222b can be spaced apart from the inner liner 60, which can reduce the contact area between the chassis 10 and the inner liner 60, thereby preventing the protruding structure at the bottom of the inner liner 60 from impacting the second part 222b and causing the second part 222b to deform when the dishwasher vibrates.

[0038] In some embodiments, the partition pad 30 may extend along the length direction of the second plate 221c, and the two ends of the partition pad 30 may respectively abut against the two second side plates 222, so as to use the second side plates 222 to limit the partition pad 30 and prevent the partition pad 30 from sliding towards the second side plates 222.

[0039] Furthermore, the partition pad 30 can cover the bearing surface 221a to further increase the area of ​​the partition pad 30, thereby increasing the contact area between the partition pad 30 and the bottom surface of the inner liner 60, so that the partition pad 30 can play a better role in buffering and shock absorption, and can provide more stable support for the inner liner 60.

[0040] In some embodiments, the outer surfaces of both the first side plate 221 and the second side plate 222 may be provided with reinforcing structures 40. The reinforcing structures 40 can improve the structural strength of the first side plate 221 and the second side plate 222 and prevent the first side plate 221 and the second side plate 222 from bending and deforming. Specifically, the reinforcing structure 40 may be a grid-like reinforcing rib structure.

[0041] like Figure 2 As shown, in some embodiments of this application, the chassis 10 further includes a third side plate 223 and a connecting component 50. The third side plate 223 is disposed opposite to the first side plate 221 and connected to the base plate 21. The top surface of the third side plate 223 is lower than the bearing surface 221a. The connecting component 50 is disposed opposite to the first side plate 221 and is used to connect the chassis 10 and the inner liner 60. It can be understood that when the bearing surface 221a supports the inner liner 60, the third side plate 223 can be spaced apart from the inner liner 60, which can reduce the contact area between the chassis 10 and the inner liner 60, thereby preventing the protruding structure at the bottom of the inner liner 60 from impacting the third side plate 223 and causing the third side plate 223 to deform when the dishwasher vibrates. At the same time, taking the bearing surface 221a supporting the first side of the bottom surface of the inner liner 60 as an example, the connecting component 50 is disposed opposite to the first side plate 221, and can provide support for the second side of the bottom surface of the inner liner 60 that is disposed opposite to the first side, thereby making the inner liner 60 more stable.

[0042] Further, the distance between the connecting component 50 and the first side plate 221 is greater than the distance between the connecting component 50 and the third side plate 223, so that the connecting component 50 is closer to the second side of the bottom surface of the inner container 60, thereby providing better support for the second side of the bottom surface of the inner container 60 and preventing the inner container 60 from tilting.

[0043] Specifically, the connecting component 50 includes a connecting piece 51 and a fixing piece 52. The connecting piece 51 includes two first connecting plates 511 and a second connecting plate 512 located between the two first connecting plates 511. The two first connecting plates 511 are arranged at intervals along the length direction of the partition pad 30, and the two first connecting plates 511 are respectively used to be placed on both sides of the inner container 60. The second connecting plate 512 is used to be placed above the inner container 60, and both ends of the second connecting plate 512 are respectively connected to the two first connecting plates 511 to form a "U-shaped" connecting piece 51. The inner container 60 can be limited and fixed through the connecting piece 51. The fixing piece 52 is connected to the first connecting plate 511 and the disk body 20 to realize the connection between the connecting piece 51 and the disk body 20.

[0044] Further, a slot 23 is provided on the disk body 20, and the end of the fixing piece 52 is inserted into the slot 23 to provide positioning and installation of the fixing piece 52 on the disk body 20 through the slot 23.

[0045] In a second aspect, the present application further provides a dishwasher, as Figure 3 and Figure 4 shown. The dishwasher includes an inner container 60 and a chassis 10 as described in any one of the above embodiments. The inner container 60 is located above the chassis 10. A part of the bottom surface of the inner container 60 is placed on the partition pad 30 and contacts the partition pad 30, and the bottom surface of the inner container 60 is spaced from the bearing surface 221a.

[0046] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
