More and more families are starting to install and use dishwashers. Dishwashers not only bring convenience to people, but also save people's time. With the advancement of science and technology, people's quality of life is getting higher and higher. They not only require dishwashers to wash cleanly, but also hope to have a better sterilization effect.

[0003] At present, cabinet dishwashers are becoming more and more popular in the market. Most cabinet dishwashers are designed with two-layer or three-layer bowl racks. For details, please refer to the Chinese utility model patent "A Dishwasher" with patent application number CN202120954010.4 (publication number CN216060428U).

[0004] Cabinet dishwashers are generally installed under the kitchen cabinet countertop, so users need to bend down when placing or taking tableware, especially the bottom dish rack. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a pull-out basket cabinet that can be used to take and place items without bending over, in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a pull-out basket cabinet which can prevent the pull-out basket from rotating after it is raised to an extreme state.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a pull-out basket cabinet, comprising

[0008] A cabinet body having a receiving cavity inside and an opening at the front; and

[0009] A pull-out basket can be pulled forward and backward through the opening on the front side of the cabinet to enter and exit the accommodating cavity;

[0010] The feature is that it also includes two groups of lifting components respectively located on the left and right sides of the pull-out basket, and each group of the lifting components includes

[0011] The guide rail is arranged on the inner wall of the cabinet along the front-to-back direction, a slide groove extending along the front-to-back direction is provided on the top, and a clearance hole intersecting the slide groove is provided on the bottom side of the front part;

[0012] A fixing frame, fixed relative to the pull-out basket;

[0013] A support bar, the top end of which is rotatably connected to the fixing frame, the bottom end of which is movably inserted into the sliding groove, and a slot is provided on the bottom end surface; and

[0014] The electric push rod comprises a push rod seat fixed relative to the cabinet body and a push rod core capable of being telescopic relative to the push rod seat, wherein the top end of the push rod core is directly opposite to the clearance hole;

[0015] During the forward movement of the pull-out basket, the bottom end of the support bar moves forward synchronously in the slide slot until it abuts against the front end surface inside the slide slot;

[0016] As the pull-out basket continues to move forward, the pull-out basket flips upward with the bottom end of the support bar as the rotation center until the top of the push rod core faces the slot, so that the push rod core can pass through the clearance hole in an extended state and be inserted into the slot for locking.

[0017] In order to facilitate users to draw out the pull-out basket, a pull rod is provided at the front of the pull-out basket.

[0018] In order to facilitate the control of the electric push rod, a touch sensor is provided on the pull rod, and the pull-out basket cabinet has a controller, which is electrically connected to the touch sensor and the electric push rod, so that the controller can receive the signal collected by the touch sensor and control the extension and retraction of the push rod core of the electric push rod.

[0019] In order to conveniently control the extension and retraction of the push rod core, the touch sensor has a first sensing area and a second sensing area;

[0020] When the user touches the first sensing area, the controller controls the push rod core of the electric push rod to extend outward;

[0021] When the user touches the second sensing area, the controller controls the push rod core of the electric push rod to retract.

[0022] In order to facilitate the user to identify the two sensing areas, the first sensing area and the second sensing area are respectively provided with a first reminder mark and a second reminder mark.

[0023] In order to further solve the second technical problem mentioned above, in the two groups of lifting assemblies, the rotation axes between the support bars and the fixing frames are not colinear.

[0024] In order to improve the stability of the pull-out basket, in the two groups of lifting assemblies, the rotation axes between the support bars and the fixing frames are on the same horizontal plane and are arranged at intervals in the front-to-back direction.

[0025] In order to facilitate the placement of tableware, when the push rod core is inserted into the slot, the pull-out basket is arranged substantially horizontally.

[0026] In order to ensure that the pull-out basket rises to the limit position, when the push rod core is inserted into the slot, the support bar is arranged vertically.

[0027] In order to facilitate the installation of the guide rail on the cabinet, a first mounting hole is provided on the cabinet, and the guide rail has a mounting strip, which has a second mounting hole corresponding to the first mounting hole. The mounting strip is connected to the cabinet by inserting fasteners in the second mounting hole and the first mounting hole in sequence.

[0028] In order to facilitate the adjustment of the lifting distance of the pull-out basket and meet the usage requirements of different users, the first mounting holes are arranged in rows, and each row of first mounting holes is arranged at intervals in the vertical direction. In each row of first mounting holes, each first mounting hole corresponds to the second mounting hole one by one, and is arranged at intervals in the front-to-back direction.

[0029] In order to give the pull-out basket a sufficiently long translation stroke and to avoid interference with other components during the movement of the pull-out basket as much as possible, the fixing frame is installed at the rear of the pull-out basket.

[0030] In order to facilitate the translation of the pull-out basket, a slide rail is provided in the cabinet, and a pulley is rotatably connected to the bottom of the pull-out basket. The pulley can be slidably moved forward and backward and rested on the slide rail.

[0031] Compared with the prior art, the advantages of the present invention are:

[0032] (1) The lifting assembly is composed of a guide rail, a fixing bar, a support bar and an electric push rod. When the basket moves forward, the bottom end of the support bar moves forward synchronously in the slide slot until it abuts against the front end surface inside the slide slot. When the basket continues to move forward, the basket turns upward with the bottom end of the support bar as the rotation center until the top end of the push rod core faces the slot, so that the push rod core can pass through the clearance hole in the extended state and be inserted into the slot for locking. On the one hand, the basket automatically moves upward during the basket's forward movement, and the user can take and put items without bending over. The structure is ingenious and flexible, which enhances the user's experience. On the other hand, when the basket moves forward, it first moves horizontally and then moves forward and upward, which can avoid interference with other components.

[0033] (2) Through the telescopic movement of the push rod core of the electric push rod, on the one hand, the support rod can be locked and unlocked, and on the other hand, the height of the pull-out basket can be finely adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] There are two pull-out baskets 2, which are arranged one above and one below in the above-mentioned accommodating cavity 11. For the pull-out basket 2 located at the bottom, the left and right sides of the bottom of the pull-out basket 2 are rotatably connected with a plurality of pulleys 21 corresponding to the above-mentioned slide rails 13, and each pulley 21 can be slidably placed on the corresponding slide rails 13 forward and backward, so that the pull-out basket 2 can be pulled forward and backward through the opening on the front side of the cabinet 1 to enter and exit the accommodating cavity 11; the front part of the pull-out basket 2 has a pull rod 22, and the pull rod 22 is provided with a touch sensor 221, and the touch sensor 221 has a first sensing area 2211 and a second sensing area 2212 arranged in sequence along the left and right directions, and the first sensing area 2211 and the second sensing area 2212 are respectively provided with a first reminder mark and a second reminder mark, and the above first reminder mark and second reminder mark can be set with different colors, patterns or texts according to needs.

[0046] There are two groups of lifting components 3 , which are respectively arranged on the left and right sides of the pull-out basket 2 located below. Each group of lifting components 3 includes a guide rail 31 , a fixing frame 32 , a support bar 33 and an electric push rod 34 .

[0047] Specifically, the guide rail 31 is arranged on the side wall inside the cabinet 1 along the front-to-back direction; the top of the guide rail 31 is provided with a slide groove 311 extending along the front-to-back direction; the bottom side of the front part of the guide rail 31 is provided with a clearance hole 312 intersecting with the slide groove 311; the bottom of the guide rail 31 is provided with a mounting bar 313, and the mounting bar 313 is provided with second mounting holes 3131 corresponding to the first mounting holes 12 in each row of first mounting holes 12, and the mounting bar 313 is connected to the cabinet 1 by sequentially inserting fasteners in the second mounting holes 3131 and the first mounting holes 12. The user can select the first mounting holes 12 of appropriate heights to match the second mounting holes 3131 according to the needs, so as to install the guide rail 31 at a suitable position on the side wall of the cabinet 1.

[0048] The fixing frame 32 is clamped on the rear part of the pull-out basket 2 , and a rotating shaft 321 is convexly provided on the outer surface of the fixing frame 32 .

[0049] The top of the support bar 33 has a sleeve 331 which can be rotatably sleeved on the outer periphery of the rotating shaft 321 ; the bottom of the support bar 33 can be movably inserted in the slide groove 311 ; a slot 332 is provided on the bottom end surface of the support bar 33 .

[0050] The electric push rod 34 includes a push rod seat 341 installed on the inner wall of the cabinet 1 and a push rod core 342 that can be telescoped along the vertical direction relative to the push rod seat 341 , and the top end of the push rod core 342 is directly opposite to the clearance hole 312 .

[0051] It should be noted that, in this embodiment, Figure 4As shown, the two sets of lifting components 3 are not arranged symmetrically, and the rotation axes between the support bars 33 and the fixing frames 32 in the two sets of lifting components 3 are on the same horizontal plane and are arranged at intervals in the front-to-back direction. In other words, in the two sets of lifting components 3, the rotation axes between the support bars 33 and the fixing frames 32 are not colinear. In addition, when the pull-out basket 2 is in the initial position, the pull-out basket 2 is arranged horizontally. Such a design can not only keep the pull-out basket 2 in a horizontal state during the movement.

[0052] In addition, the pull-out basket cabinet has a controller, which is electrically connected to the touch sensor 221 and the electric push rod 34, so that the controller can receive the signal collected by the touch sensor 221 and control the extension and retraction of the push rod core 342 of the electric push rod 34. Specifically, when the user touches the first sensing area 2211, the controller controls the push rod core 342 of the electric push rod 34 to extend outward; when the user touches the second sensing area 2212, the controller controls the push rod core 342 of the electric push rod 34 to retract inward.

[0053] like Figure 5 As shown, during the forward movement of the pull-out basket 2, the bottom end of the support bar 33 moves forward synchronously in the slide groove 311 until it abuts against the front end surface inside the slide groove 311 (as shown in FIG. Figure 6 shown);

[0054] As the pull-out basket 2 continues to move forward, the pull-out basket 2 turns upward with the bottom end of the support bar 33 as the rotation center until the support bar 33 is arranged vertically. Figure 7 As shown, at this time, the top end of the push rod core 342 is facing the slot 332, so that the push rod core 342 can pass through the clearance hole 312 in the extended state and be inserted into the slot 332 for locking.

[0055] The working principle of this embodiment is as follows:

[0056] (1) When it is necessary to pull out the pull-out basket 2 located below:

[0057] like Figure 5 As shown, the pull-out basket 2 is in the initial position, and the bottom end of the support bar 33 is inserted into the rear part of the slide slot 311;

[0058] First, pull the pull rod 22 forward, the pulley 21 of the pull basket 2 moves forward along the slide rail 13, and the support bar 33 moves forward in the slide groove 311 synchronously until it moves to the position as shown in FIG. Figure 6 The middle position shown, at this time, the bottom end of the support bar 33 abuts against the front end surface inside the slide groove 311;

[0059] Then, the pull rod 22 is continuously pulled forward, and a fulcrum is formed at the bottom end of the support bar 33. The pull basket 2 turns upward with the fulcrum as the rotation center, and rises while moving forward. At the same time, the pulley 21 gradually moves away from the slide rail 13 until it moves to the position as shown in FIG. Figure 7The working position shown in the figure, at this time, the support bar 33 is arranged vertically, and the top of the push rod core 342 is facing the slot 332. It only needs to touch the first sensing area 2211 to make the controller control the push rod core 342 of the electric push rod 34 to extend outward, and the push rod core 342 will pass through the clearance hole 312 and be inserted into the slot 332 for locking. At the same time, because the rotation axis between the support bar 33 and the fixing frame 32 in the two sets of lifting components 3 is not colinear, at this time, the pull rod 22 is released, and the pull basket 2 is still stably maintained in a horizontal state. At this time, the user does not need to bend down to take and put tableware, and can achieve fine adjustment of the height of the pull basket 2 by touching the first sensing area 2211 and the second sensing area 2212 (such as Figure 8 shown);

[0060] (2) When it is necessary to push back the pull-out basket 2 located below:

[0061] Just touch the second sensing area 2212 to make the controller control the push rod core 342 of the electric push rod 34 to retract, and the push rod core 342 is released from the slot 332 to be unlocked;

[0062] Then push the pull rod 22 backward, the pull basket 2 turns downward with the bottom end of the support bar 33 as the rotation center, and descends while moving backward until it moves to the position as shown in FIG. Figure 6 The intermediate position shown, at which the pulley 21 contacts the slide rail 13;

[0063] Then, the pull rod 22 is pushed backwards, and the pulley 21 of the pull basket 2 moves backwards along the slide rail 13, and the support bar 33 moves backwards in the slide groove 311 synchronously until it moves to the position as shown in FIG. Figure 5 Initial position shown.
