[0044] Example 1

[0045] See also Figure 1 and Figure 3 As shown, this embodiment provides a storage cabinet, which includes a balancing system, a cabinet body 1 with a first cavity therein, and a door assembly 2 rotatably connected to the cabinet body 1 and capable of opening and closing the opening of the first cavity; the balancing system includes multiple groups of elastic devices 3 connected to the door assembly 2 to jointly balance the torque of the door assembly 2 and an adjustment device 4 that can simultaneously pull the multiple groups of elastic devices 3 to simultaneously adjust the elastic preload force of the multiple groups of elastic devices 3.

[0046] With such an arrangement, after the user replaces the door assembly 2, the elastic preload forces of multiple sets of elastic devices 3 are adjusted simultaneously through the adjustment device 4 to support the door assembly 2, so that the torque of the elastic preload forces of the elastic devices 3 can balance the torque of the gravity of the door assembly 2, thereby allowing the door assembly 2 to remain stationary when opened.

[0047] The provision of multiple sets of elastic devices 3 provides more reliable support for door assembly 2, and adjustment device 4 can simultaneously adjust the elastic preload force of multiple sets of elastic devices 3, enabling adjustment of the support force value of door assembly 2 over a wider range, thereby enabling the balancing system to balance door assemblies 2 over a wider weight range. In addition, the elastic preload force of multiple sets of elastic devices 3 can be adjusted simultaneously through adjustment device 4, without having to adjust the elastic preload force of multiple sets of elastic devices 3 separately, making balancing adjustment of door assembly 2 more convenient.

[0048] In summary, the storage cabinet alleviates the technical problem of the prior art that the range of balance adjustment for door assemblies 2 of different weights is limited and the adjustment is inconvenient. It should be noted that the dishwasher includes the above-mentioned storage cabinet, wherein the cabinet body 1 of the storage cabinet serves as the body of the dishwasher. Therefore, the technical problem of the prior art that the range of balance adjustment for door assemblies of different weights is limited and the adjustment is inconvenient is alleviated.

[0049] Optionally, the upper end of the door assembly 2 is rotatably connected to the cabinet body 1, or the lower end of the door assembly 2 is rotatably connected to the cabinet body 1, which is not limited here. For example, see Figure 3 In this figure, the lower end of the door assembly 2 is rotatably connected to the cabinet body 1, and the handle is provided near the upper end of the door assembly 2 to facilitate opening and closing the door assembly 2.

[0050] It should be noted that the storage cabinet can also be a household appliance with a door assembly 2 such as a microwave oven, oven or steamer, or furniture with a door assembly 2 such as a cupboard, wardrobe or cabinet. There is no limitation here. The following description takes the storage cabinet as a dishwasher as an example.

[0051] Optionally, the adjusting device 4 includes a threaded connector screwed to the cabinet 1 , and the multiple sets of elastic devices 3 are all connected to the threaded connector. When the threaded connector is tightened, the threaded connector can pull the multiple sets of elastic devices 3.

[0052] Optionally, the elastic device 3 is provided with two, three, four or five groups, etc., wherein multiple groups of elastic devices 3 can be respectively provided on both sides of the cabinet body 1, or, multiple groups of elastic devices 3 are dispersedly provided on both sides and the rear side of the cabinet body 1, or, multiple groups of elastic devices 3 are all provided on the rear side of the cabinet body 1.

[0053] Preferably, see Figure 2 and Figure 4 As shown, combined with Figure 5 and Figure 6 In this embodiment, two groups of elastic devices 3 are provided, and the adjusting device 4 includes a limiting structure 43, a first pull rope 44, a slide rail 41 fixed relative to the cabinet 1, and a slider 42 movably connected to the slide rail 41; along the moving direction perpendicular to the slider 42, the limiting structure 43 and the slider 42 are spaced apart, the first pull rope 44 is provided between the limiting structure 43 and the slider 42, and the two groups of elastic devices 3 are respectively connected to the two ends of the first pull rope 44.

[0054] With this arrangement, when the slider 42 moves along the slide rail 41 toward one end of the first pull rope 44, the slider 42 can drive the first pull rope 44 to move along with it. The first pull rope 44 slides along the limiting structure 43. Under the limiting action of the limiting structure 43, the first pull rope 44 can bend with the slider 42 and the limiting structure 43 as the folding point. As the slider 42 moves further, the bent length of the first pull rope 44 increases, allowing the first pull rope 44 to simultaneously pull the elastic devices 3 at both ends, thereby adjusting the elastic preload of the two sets of elastic devices 3. Specifically, when the slider 42 moves a short distance, the bent length of the first pull rope 44 is shorter, and the increase in the elastic force of the elastic device 3 is smaller. When the slider 42 moves a long distance, the bent length of the first pull rope 44 is longer, and the increase in the elastic force of the elastic device 3 is larger. Therefore, the adjustment device 4 has a wide range of adjustment for the elastic preload of the elastic device 3, and adjustment is convenient.

[0055] Preferably, see Figure 4In this embodiment, a push block 45 is provided on the slider 42, and a push groove matching the first pull rope 44 is provided on the push block 45, and the first pull rope 44 is provided in the push groove, so that the slider 42 pushes the first pull rope 44 to move through the push block 45, wherein the setting of the push groove prevents the first pull rope 44 from moving relative to the push block 45 during the movement.

[0056] Preferably, see Figure 4-Figure 6 As shown, in this embodiment, there are two limiting structures 43 , which are respectively disposed on both sides of the slider 42 , and both limiting structures 43 are disposed on the same side of the first pull rope 44 .

[0057] Among them, when the slider 42 drives the first pull rope 44 to move along the slide rail 41 toward one end close to the first pull rope 44, under the limiting action of the limiting structure 43, the first pull rope 44 can be folded with the two limiting structures 43 as breaking points at the same time. With this arrangement, the movement of the slider 42 makes the stretching effect of the first pull rope 44 on the elastic device 3 more significant, thereby improving the adjustment sensitivity of the balance system.

[0058] Preferably, see Figure 4 As shown, in this embodiment, the limiting structure 43 is a first guide wheel provided with a first guide groove matching the first pull rope 44, and the first pull rope 44 passes through the first guide groove.

[0059] With this arrangement, when the slider 42 drives the first pull rope 44 to move relative to the limiting structure 43 , the wear between the limiting structure 43 and the first pull rope 44 is reduced, thereby extending the service life of the limiting structure 43 and the first pull rope 44 .

[0060] Preferably, see Figure 4-Figure 6 As shown, in this embodiment, the adjustment device 4 also includes a main body 46 fixed to the cabinet 1, and the slide rail 41 is fixed to the main body 46; a slide groove 461 matching the first pull rope 44 is opened on the main body 46, and the first pull rope 44 is connected to the elastic device 3 through the slide groove 461.

[0061] Preferably, two slide grooves 461 are provided, and both ends of the first pull rope 44 are connected to the elastic device 3 through the slide grooves 461 .

[0062] The setting of the slide groove 461 provides guidance and limiting functions for the movement of the first pull rope 44, preventing the first pull rope 44 from shifting during the movement, so that the first pull rope 44 pulls the elastic device 3 to adjust the balance of the door assembly 2 more accurately.

[0063] Preferably, see Figure 1-Figure 3 As shown, in this embodiment, the adjustment device 4 is arranged at the top of the cabinet 1. Such an arrangement allows the user to adjust the adjustment device 4 without bending or squatting, thereby improving the convenience of adjustment.

[0064] Preferably, see Figure 2 and Figure 3 As shown, in this embodiment, two sets of elastic devices 3 are respectively arranged on both sides of the cabinet; the balancing system also includes a guide rod 5, which is arranged on both sides of the cabinet, and the first pull rope 44 is connected to the elastic device 3 after being reversed by the guide rod 5.

[0065] Preferably, a third guide groove is provided on the guide rod 5 , and the first pull rope 44 passes through the third guide groove, so as to further limit the position of the first pull rope 44 .

[0066] The guide rod 5 is provided to facilitate the reversal of the first pull rope 44 and prevent the first pull rope 44 from contacting the cabinet body and generating friction during movement, thereby affecting the service life of the first pull rope 44 .

[0067] Preferably, see Figure 4-Figure 6 As shown, in this embodiment, the slide rail 41 is a lead screw, the slider 42 is screwed to the lead screw, and during the rotation of the lead screw, the slider 42 can move along the lead screw; the accommodating cabinet also includes a top plate arranged above the cabinet body 1, and a second cavity is arranged between the top plate and the cabinet body 1, the adjusting device 4 is arranged in the second cavity and the end of the lead screw is close to the opening of the second cavity; the door assembly 2 can open and close the opening of the second cavity.

[0068] With this arrangement, when the slider 42 needs to be moved, it is only necessary to rotate the lead screw. Opening the door assembly 2 can open the openings of the first cavity and the second cavity. When the opening of the second cavity is opened, the end of the lead screw disposed at the opening of the second cavity is exposed, so that the lead screw can be operated by the end to rotate it without disassembling the cabinet 1, making it more convenient to adjust the adjustment device 4. For example, the lead screw can be rotated by using a screwdriver, pliers, or pliers.

[0069] Preferably, a limiting groove 462 matching the slider 42 is provided on the body 46, and the extension direction of the limiting groove 462 is consistent with the extension direction of the screw to provide a limiting and guiding effect on the movement of the slider 42 to prevent the slider 42 from shaking during movement.

[0070] Preferably, see Figure 4-Figure 6 The end of the screw near the opening of the second cavity is provided with a rotating structure 411, which rotates the screw to facilitate the adjustment of the adjustment device 4. Preferably, the rotating structure 411 is provided with an outer hexagonal structure, an outer pentagonal structure or an inner hexagonal structure.

[0071] Preferably, see Figure 3As shown, in this embodiment, the elastic device 3 includes an elastic member 31 and a second pull rope 32 . The second pull rope 32 is connected to the first pull rope 44 through the elastic member 31 , and one end of the second pull rope 32 away from the elastic member 31 is connected to the door assembly 2 .

[0072] Optionally, the elastic member 31 is a spring, a tension spring or a spring sheet, etc. Optionally, the first pull rope 44 is connected to the elastic member 31 by hanging, bonding or tying.

[0073] With this arrangement, the elastic preload force of the elastic member 31 is adjusted by adjusting the adjusting device 4 , so that the elastic member 31 pulls the door assembly 2 through the second pull rope 32 to balance the torque of the door assembly 2 due to gravity.

[0074] Preferably, see Figure 3 As shown, in this embodiment, the door assembly 2 includes a door body 21 and a hinge 22 rotatably connected to the cabinet body 1. The door body 21 and the second pull rope 32 are both fixed to the hinge 22 and are respectively arranged on both sides of the rotation center of the hinge 22.

[0075] With such an arrangement, the elastic member 31 can apply tension to the hinge 22 through the second pull rope 32, and the door body 21 can apply another force to the hinge 22 under the action of gravity. Since the door body 21 and the second pull rope 32 are respectively arranged on both sides of the rotation center of the hinge 22, the tension and the above another force act on both sides of the rotation center of the hinge 22 respectively. Among them, the elastic preload force of the elastic member 31 is adjusted by the adjustment device 4 so that the hinge 22 can be balanced, so that the door body 21 can remain stationary when opened.

[0076] Alternatively, see Figure 3 In this embodiment, a hook 33 is provided on the second pull rope 32 , and a hanging opening is provided on the hinge 22 . The hook 33 is hung on the hanging opening, thereby securing the second pull rope 32 to the hinge 22 .

[0077] Optionally, the hinge 22 is provided above the door body 21 so that the door body 21 is a bottom-opening door type, or the hinge 22 is provided below the door body 21 so that the door body 21 is a top-opening door type.

[0078] Optionally, the hinge 22 is connected to the cabinet 1 by rotation, wherein the rotation center of the hinge 22 is the rotation center of the shaft.

[0079] Preferably, see Figure 3 As shown, in this embodiment, the balancing system also includes a second guide wheel 6 installed on the cabinet body, and the second pull rope 32 is fixed to the hinge 22 after being changed by the second guide wheel 6, so that the pulling force of the second pull rope 32 on the hinge 22 has a component force consistent with the direction of gravity of the door body 21.

[0080] Optionally, the first guide wheel and the second guide wheel 6 are pulleys or rollers.

[0081] With this arrangement, the tension exerted on the hinge 22 by the second pull cord 32 has a component aligned with the direction of the gravity of the door body 21, and the point of application of this component and the point of application of the gravity of the door body 21 on the hinge 22 are located on either side of the rotation center of the hinge 22, thereby achieving a balanced state for the hinge 22. Specifically, when the elastic preload force of the elastic member 31 is adjusted by the adjustment device 4 so that the torque exerted on the hinge 22 by the elastic member 31 is equal to the torque exerted on the hinge 22 by the gravity of the door body 21, the hinge 22 is balanced, enabling the door body 21 to remain stationary.

[0082] Among them, see Figure 5 In the adjusting device 4, the distance that the slider 42 moves is small. Therefore, the bending length of the first pull rope 44 is small, and the pulling force of the first pull rope 44 on the elastic member 31 is small, so that the elastic preload force of the elastic member 31 is small, which is suitable for the door assembly 2 with smaller mass; see Figure 6 In the adjusting device 4, the distance that the slider 42 moves is large, so the bending length of the first pull rope 44 is large, and the pulling force of the first pull rope 44 on the elastic member 31 is large, so that the elastic preload force of the elastic member 31 is large, which is suitable for door assemblies 2 with larger mass.

[0083] Example 2

[0084] A second embodiment provides a dishwasher, which includes the storage cabinet of the first embodiment. The technical features of the storage cabinet disclosed in the first embodiment are also applicable to this embodiment, and the technical features of the storage cabinet disclosed in the first embodiment are not repeated here. The following describes the embodiment of the dishwasher in further detail with reference to the accompanying drawings.

[0085] To save space, the improved features of this embodiment are also reflected in Figures 1-6 Therefore, combined Figures 1-6 The scheme of this embodiment will be described.

[0086] See also Figures 1-6 As shown, the dishwasher provided in this embodiment includes the above-mentioned storage cabinet, and the cabinet body 1 of the storage cabinet is the body of the dishwasher.

[0087] Such a setting alleviates the technical problem in the prior art that the range of balance adjustment of the dishwasher for door assemblies 2 of different weights is small and the adjustment is inconvenient, thereby improving the user experience of the dishwasher.

[0088] The first cavity is used to accommodate tableware to facilitate cleaning of the tableware.

[0089] It should be noted that, in the dishwasher, when the weight of the replaced door body 21 is large, the door body 21 is opened to open the opening of the second cavity, thereby exposing the end of the screw, and the screw is rotated by a tool to make the slider 42 drive the push block 45 thereon to move, thereby the push block 45 drives the first pull rope 44 to move, wherein the first pull rope 44 can be folded with the two limiting structures 43 as the folding point, and the folded first pull rope 44 can simultaneously pull the two elastic members 31 in the direction away from the second pull rope 32, thereby increasing the elastic preload of the elastic member 31 The force increases the tension of the elastic member 31 on the hinge 22 through the second pull rope 32, wherein the tension of the second pull rope 32 on the hinge 22 is adjusted by adjusting the sliding distance of the slider 42, so that the torque of this tension on the hinge 22 is equal to the torque of the gravity of the door body 21 on the hinge 22, the hinge 22 reaches a balanced state, therefore, the door body 21 fixed to the hinge 22 reaches a balanced state, which can reduce the force required by the user to open the door body 21, and the door body 21 can be stably maintained in the rest position when the user opens the door body 21.

[0090] The dishwasher of this embodiment has the advantages of the storage cabinet of the first embodiment, which have been described in detail in the first embodiment and will not be repeated here.
