Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen equipment technology, specifically to a storage cabinet. Background Technology
[0002] With the improvement of living standards, dishwashers are being used more and more as kitchen appliances. Existing dishwashers generally have multiple racks. In order to accommodate tableware of different sizes in the dishwasher, the upper rack is usually equipped with an adjustable lifting structure that allows the upper rack to be raised and lowered within the dishwasher's inner drum. By adjusting the distance between the upper rack and the top wall of the inner drum, tableware of different sizes can be placed.
[0003] The existing upper dish rack adjustment mechanism has slots of different heights on the left and right sides of the dish rack, allowing the support mechanism of the upper dish rack to be engaged in the slots of different heights to achieve the adjustment of the dish rack height. For details, please refer to Chinese patent application number CN201320218217.0, "A Dishwasher".
[0004] However, the above solution has two drawbacks. First, each time the height of the dish rack is changed, the entire dish rack needs to be disassembled and reinstalled, making the dish rack heavy and inconvenient to operate. Second, it is easy to encounter a situation where one side has been adjusted but the other side is still stuck at a different height, meaning that one side of the dish rack is higher than the other, and the operation has to be repeated. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a storage cabinet with adjustable shelf height and simple operation, in light of the current state of the technology.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a storage cabinet, including...
[0007] The cabinet has an internal cavity and an open front.
[0008] A shelf is disposed within the aforementioned receiving cavity; and
[0009] Two sets of height adjustment components are located on the left and right sides of the shelf, respectively, for adjusting the height of the shelf;
[0010] Its characteristic is that: both the left and right sides of the shelf have first limiting members;
[0011] Each of the height adjustment components includes:
[0012] Mounting plate, installed on the cabinet, and the shelf is mounted on the mounting plate that can move up and down;
[0013] A lever, rotatably connected to the mounting plate, has a support arm at its tail for supporting the first limiting member; and
[0014] An elastic element acts between the mounting plate and the lever so that the support arm of the lever always tends to be supported below the first limiting element.
[0015] The lever can rotate under the action of external force to overcome the elastic force of the elastic element, so that the support arm releases the support of the first limiting element, thereby allowing the shelf in the high position to move to the low position under the action of gravity.
[0016] To cushion the descending shelf, the shelf has second limiting members on both the left and right sides. Each height adjustment component also includes a buffer device, which is mounted on the mounting plate and located directly below the second limiting members. When the shelf is in a low position, the buffer device is supported below the second limiting members.
[0017] To achieve a buffering effect, the buffer device includes:
[0018] The mounting sleeve is fixed relative to the mounting plate; and
[0019] A buffer spring is housed within the mounting cylinder. The bottom end of the buffer spring abuts against the bottom plate of the mounting cylinder, and the top end of the buffer spring extends out of the mounting cylinder when no external force is applied.
[0020] In order to allow the shelf to be mounted vertically on the mounting plate, the shelf has vertical rods on both the left and right sides, and the mounting plate has guide sleeves extending in the vertical direction, which are fitted around the outer periphery of the vertical rods.
[0021] To facilitate the processing of the second limiting component, a limiting block is provided on the vertical rod at a position above the guide sleeve. This limiting block forms the second limiting component, and the buffer device is installed on the top of the guide sleeve.
[0022] To facilitate the positioning of the lever in the absence of external force, the lever is installed on the outside of the mounting plate. The support arm extends inward from the tail of the lever and gradually approaches the shelf. The mounting plate has a clearance hole for the support arm to pass through. In the absence of external force, the tail of the lever abuts against the outer surface of the mounting plate.
[0023] To facilitate the outward rotation of the support arm while lifting the shelf, the bottom surface of the support arm has a guide slope that gradually approaches the shelf from bottom to top.
[0024] To facilitate the installation of the elastic element, the side of the mounting plate has a hinge seat, and the lever is rotatably connected to the hinge seat via a rotating shaft. The elastic element is a torsion spring, which is sleeved on the outer circumference of the rotating shaft, and the two ends of the torsion spring abut against the mounting plate and the lever, respectively.
[0025] To ensure the stability of the shelf when it is in a high position, the first limiting member is a horizontal bar extending in the front-back direction, and the top surface of the support arm has a receiving groove. When the shelf is in a high position, the horizontal bar is at least partially received in the receiving groove.
[0026] To facilitate user operation of the lever, the rotation axis of the lever extends vertically, and the head of the lever extends outward from the front end of the mounting plate.
[0027] To facilitate the pulling out of the shelf, two sets of guide rail assemblies corresponding to the height adjustment component are also included. Each guide rail assembly is connected between the cabinet and the mounting plate of the corresponding height adjustment component, so that the shelf can be pulled out of the receiving cavity.
[0028] To improve the smoothness of the pull-out mechanism, each of the aforementioned guide rail assemblies includes:
[0029] The guide rail extends in the front-to-back direction;
[0030] At least two first rollers are arranged at intervals in the front-to-back direction, each first roller is rotatably connected to the inner side wall of the cabinet and housed in the guide rail;
[0031] At least two second rollers spaced apart in the front-to-back direction, each second roller rotatably connected to a mounting plate of a corresponding height adjustment component and positioned above the guide rail; and
[0032] At least one third roller is rotatably connected to the mounting plate of the corresponding height adjustment component and located below the guide rail.
[0033] Compared with the prior art, the advantages of this utility model are as follows: the height adjustment assembly is composed of a mounting plate, a lever, and an elastic element. The lever can rotate under the action of external force to overcome the elastic force of the elastic element, so that the support arm of the lever releases the support of the first limiting element of the shelf, thereby allowing the shelf in the high position to move to the low position under the action of gravity. The height of the shelf of this cabinet is adjustable and the operation is simple. After adjustment, the shelf will not be high on one side and low on the other. Attached Figure Description

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0041] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
[0042] like Figures 1 to 6 The diagram shows a preferred embodiment of the storage cabinet of this utility model. The storage cabinet can be a dishwasher, a disinfection cabinet, etc. This embodiment takes a dishwasher as an example for explanation. The dishwasher includes a cabinet body 1, a storage rack 2, a height adjustment component 3, and a guide rail component 4.
[0043] The cabinet 1 has an internal cavity 11 and an open front.
[0044] The shelf 2 is located inside the receiving cavity 11. Specifically, the shelf 2 has a horizontal bar 21 extending in the front-back direction on both the left and right sides, and two vertical bars 22 located in front of and behind the horizontal bar 21 respectively. Each vertical bar 22 has a limiting block 221 at its upper part.
[0045] There are two sets of height adjustment components 3, symmetrically arranged on the left and right sides of the shelf 2, for adjusting the height of the shelf 2. In this embodiment, each height adjustment component 3 includes a mounting plate 31, a lever 32, an elastic element 33, and a buffer device 34.
[0046] Specifically, the mounting plate 31 is mounted on the cabinet 1 via the guide rail assembly 4; the outer side of the mounting plate 31 has a hinge seat 310; the mounting plate 31 is provided with a clearance hole 311 at the position behind the hinge seat 310; both the front and rear sides of the mounting plate 31 are provided with vertically extending guide sleeves 312, which correspond one-to-one with the vertical rods 22 and are fitted around the outer periphery of the corresponding vertical rods 22 so that the shelf 2 can be mounted on the mounting plate 31 in a vertically movable manner.
[0047] The lever 32 is located on the outside of the mounting plate 31. The middle part of the lever 32 is rotatably connected to the hinge seat 310 through a vertically arranged pivot 320. The tail of the lever 32 has a support arm 321 that extends inward and gradually approaches the shelf 2. The support arm 321 can pass through the clearance hole 311 and extend into the inside of the mounting plate 31 to support the crossbar 21. The bottom surface of the support arm 321 has a guide slope 3211 that gradually approaches the shelf 2 from bottom to top. The top surface of the support arm 321 has a receiving groove 3212. The head of the lever 32 extends outward from the front end of the mounting plate 31.
[0048] The elastic element 33 is a torsion spring, which is sleeved on the outer periphery of the rotating shaft 320. The two ends of the torsion spring abut against the mounting plate 31 and the lever 32 respectively, so that the support arm 321 of the lever 32 always tends to be supported under the crossbar 21. In the absence of external force, the tail of the lever 32 abuts against the outer surface of the mounting plate 31.
[0049] There are two buffer devices 34, corresponding one-to-one with the guide sleeves 312. Each buffer device 34 is installed on the top of the corresponding guide sleeve 312 and located directly below the corresponding limiting block 221. In this embodiment, the buffer device 34 includes a mounting cylinder 341 and a buffer spring 342. Specifically, the mounting cylinder 341 is connected to the top of the corresponding guide sleeve 312 and is sleeved on the outer periphery of the vertical rod 22; the buffer spring 342 is housed in the mounting cylinder 341 and is sleeved on the outer periphery of the vertical rod 22. The bottom end of the buffer spring 342 abuts against the bottom plate of the mounting cylinder 341, and the top end of the buffer spring 342 extends out of the mounting cylinder 341 when no external force is applied.
[0050] There are two sets of guide rail assemblies 4, each corresponding to one of the height adjustment assemblies 3. Each guide rail assembly 4 is connected between the cabinet 1 and the mounting plate 31 of the corresponding height adjustment assembly 3, so that the shelf 2 can be pulled out and out of the receiving cavity 11. In this embodiment, each guide rail assembly 4 includes a guide rail 41, a first roller 42, a second roller 43, and a third roller 44.
[0051] Specifically, guide rail 41 extends in the front-to-back direction;
[0052] There are two first rollers 42, which are arranged at intervals in the front-to-back direction. Each first roller 42 is rotatably connected to the inner side wall of the cabinet 1 and housed in the guide rail 41.
[0053] There are two second rollers 43, which are arranged at intervals in the front-back direction. Each second roller 43 is rotatably connected to the mounting plate 31 of the corresponding height adjustment component 3 and is located above the guide rail 41.
[0054] There is one third roller 44, which is rotatably connected to the mounting plate 31 of the corresponding height adjustment component 3 and located below the guide rail 41.
[0055] The aforementioned lever 32 can rotate under the action of external force to overcome the elastic force of the elastic element 33, so that the support arm 321 releases its support from the crossbar 21, thereby allowing the shelf 2, which is in a high position, to move to a low position under the action of gravity.
[0056] When shelf 2 is in a high position, such as Figure 3 As shown, the support arm 321 is supported below the crossbar 21, and the bottom of the crossbar 21 is accommodated in the receiving groove 3212;
[0057] When shelf 2 is in a low position, such as Figure 6 As shown, the buffer device 34 is supported below the limiting block 221.
[0058] The working principle of this embodiment is as follows: Figure 3 As shown, when the shelf 2 is in a high position, the support arm 321 is supported below the crossbar 21, and the bottom of the crossbar 21 is accommodated in the receiving groove 3212.
[0059] To lower the shelf 2, simply move the head of the lever 32 inward. The support arm 321 at the tail of the lever 32 will rotate outward, gradually releasing its support on the crossbar 21. The shelf 2 will then fall along the guide sleeve 312 under gravity. As the shelf 2 descends, the limiting block 221 will contact the buffer spring 342, gradually compressing it to offset the impact, until the limiting block 221 abuts against the top of the mounting strip 341. At this point, if... Figure 6 As shown, the shelf 2 is in the low position; in addition, after releasing the lever 32, the lever 32 will return to its original position under the elastic force of the elastic element 33.
[0060] To adjust shelf 2 to a higher position, simply lift shelf 2 upwards. During this upward movement, the crossbar 21 will contact the guide ramp 3211. The upward-moving crossbar 21 will exert an outward rotational force on the support arm 321 until the crossbar 21 passes the support arm 321. At this point, the support arm 321 will return to its original position under the elastic force of the elastic element 33 and support itself below the crossbar 21. Figure 3 As shown, shelf 2 returns to its high position;
[0061] The above height adjustment method is simple to operate, and the shelf 2 will not be uneven in height after adjustment; in addition, the buffer device 34 can reduce the impact and prevent the plastic coating on the surface of the steel wire of the shelf 2 from falling off due to collision, which would cause the shelf 2 to rust.
