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 rises to the limit position.

[0007] The third technical problem to be solved by the present invention is to provide a pull-out basket cabinet capable of buffering the descending action of the pull-out basket.

[0008] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a pull-out basket cabinet, comprising

[0009] A cabinet body having a receiving cavity inside and an opening at the front; and

[0010] 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;

[0017] A locking rod, movably mounted on the support bar and insertable into the locking hole; and

[0018] An unlocking assembly, used for driving the locking rod to disengage from the locking hole;

[0019] 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;

[0020] 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 bottom end of the locking rod faces the locking hole, so that the locking rod is inserted into the locking hole for locking under the action of its own gravity.

[0021] In order to facilitate the unlocking of the first locking assembly, the unlocking assembly includes

[0022] A pull rod, mounted on the pull basket; and

[0023] The first pull rope is movably built into the pull rod, the front end of the first pull rope is exposed at the front of the pull rod, and the rear end of the first pull rope is exposed at the rear of the pull rod and connected to the top end of the locking rod.

[0024] In order to facilitate pulling the first pull rope, the unlocking assembly also includes a handle, which is connected to the front end of the first pull rope.

[0025] In order to facilitate synchronous unlocking of the two groups of first locking assemblies, the two groups of first locking assemblies share the same handle.

[0026] In order to facilitate the driving of the pull rod by the first pull rope, a steering shaft is provided on the fixing frame, and the steering shaft is located above the support bar. The rear end of the first pull rope passes around the steering shaft and is connected to the locking rod.

[0027] In order to further solve the above second technical problem, there are the following solutions:

[0028] Solution 1 is: it also includes two groups of second locking components corresponding to the lifting components one by one, which are used to lock and unlock the relative positions of the fixing frame and the support bar.

[0029] In order to lock and unlock the relative positions of the fixing frame and the support bar, the fixing frame is provided with a rotating shaft, the top end of the support bar is provided with a shaft sleeve, the shaft sleeve is rotatably sleeved on the outer circumference of the rotating shaft, and the opposite surfaces of the rotating shaft and the shaft sleeve are respectively provided with a mounting groove and a limiting hole;

[0031] A limit pin, received in the mounting groove; and

[0032] An elastic member acts between the rotating shaft and the limit pin so that the head of the limit pin always has a tendency to extend outward;

[0033] When the first locking assembly is in a locked state and the head of the limit pin is facing the limit hole, the limit pin is inserted into the limit hole under the elastic force of the elastic member to be locked.

[0034] In order to facilitate unlocking of the second locking assembly, the direction in which the pull-out basket flips around the axis of the rotating shaft under the action of gravity is recorded as the first direction, and the head of the limit pin has a guiding inclined surface extending from the inside to the outside along the first direction.

[0035] In order to facilitate the installation of the elastic member, the elastic member is a compression spring, which is accommodated in the installation groove, and the two ends of the compression spring are respectively against the inner wall of the installation groove and the end surface of the tail of the limit pin.

[0036] In order to facilitate the placement of tableware, when the second locking assembly is in a locked state, the pull-out basket is arranged substantially horizontally.

[0037] Solution 2 is: in the two groups of lifting components, the rotation axes between the support bars and the fixing frames are not colinear.

[0038] 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.

[0039] In order to facilitate the placement of tableware, when the first locking assembly is in a locked state, the pull-out basket is arranged substantially horizontally.

[0040] In order to further solve the third technical problem mentioned above, two groups of buffer components corresponding to the lifting components are also included. The buffer components act between the fixing frame and the supporting bar of the corresponding lifting component to buffer the relative rotation movement between the two.

[0041] In order to achieve the buffering function, the fixing frame is provided with a rotating shaft and a mounting shaft located above the rotating shaft, and the top end of the supporting bar is provided with a shaft sleeve, which can be rotatably sleeved on the outer periphery of the rotating shaft;

[0042] The buffer assembly includes

[0045] A second pull rope has a first end connected to the second end of the damping spring, and a second end bypassing the shaft sleeve and connected to the mounting shaft.

[0046] In order to facilitate the installation of the locking rod on the support bar, the interior of the support bar has a through hole that penetrates along the extension direction of the support bar, and the locking rod can be slidably inserted into the through hole.

[0047] In order to facilitate the locking of the locking rod by falling down and ensuring that the pull-out basket rises to the limit position, when the first locking assembly is in the locked state, the support bar is arranged vertically.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] Compared with the prior art, the advantages of the present invention are: a lifting assembly composed of a guide rail, a fixing frame and a support bar, and a first locking assembly composed of a locking rod and an unlocking assembly are installed on the side of the pull-out basket; during the forward movement of the pull-out basket, the bottom end of the support bar synchronously moves forward in the slide groove of the guide rail until it abuts against the front end surface inside the slide groove; during the continued forward movement of the pull-out basket, the pull-out basket flips upward with the bottom end of the support bar as the rotation center until the bottom end of the locking rod faces the locking hole on the guide rail, so that the locking rod can be inserted into the locking hole under the action of its own gravity for locking; on the one hand, the upward movement is automatically realized during the forward movement of the pull-out basket, and the user can take and put items without bending over; the structure is ingenious and flexible, which enhances the user experience; on the other hand, during the forward movement of the pull-out basket, it first moves horizontally and then moves forward and upward, which can avoid interference with other components.

In this embodiment, the pull rods 42 of the two groups of first locking components 4 are an integral part, and the two groups of first locking components 4 share the same handle 44.

[0073] There are two groups of second locking components 5, which are arranged on the left and right sides of the pull-out basket 2 located below, and correspond to the lifting components 3 one by one. Each group of second locking components 5 includes a limit pin 51 and an elastic member 52, which are used to lock and unlock the relative positions of the fixing frame 32 and the support bar 33. Specifically, the direction in which the pull-out basket 2 flips around the axis of the rotating shaft 321 under the action of gravity is recorded as the first direction. The limit pin 51 is accommodated in the installation groove 3211, and the head has a guiding inclined surface 511 extending from the inside to the outside along the first direction; the elastic member 52 is a compression spring, which is accommodated in the installation groove 3211, and the two ends of the compression spring are respectively against the inner wall of the installation groove 3211 and the end face of the tail of the limit pin 51, so that the head of the limit pin 51 always has a tendency to extend outward.

[0074] There are two groups of buffer components 6, which are respectively located on the left and right sides of the pull basket 2 and correspond to the lifting components 3. Each group of buffer components 6 includes a base 61, a damping spring 62 and a second pull rope 63, which are used to buffer the relative rotation of the fixing frame 32 and the support bar 33. Specifically, the base 61 is arranged on the side wall of the support bar 33; the damping spring 62 is installed on the base 61, and the first end is connected to the base 61; the first end of the second pull rope 63 is connected to the second end of the damping spring 62, and the second end bypasses the shaft sleeve 331 and is connected to the installation shaft 323.

[0075] 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);

[0076] 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 bottom end of the locking rod 41 is facing the locking hole 312, so that the locking rod 41 is inserted into the locking hole 312 under the action of its own gravity to be locked. At the same time, as shown in FIG. Figure 8 As shown, when the pull-out basket 2 is arranged substantially horizontally, the head of the limiting pin 51 faces the limiting hole 3311 , so that the limiting pin 51 is inserted into the limiting hole 3311 and locked under the elastic force of the elastic member 52 .

[0077] The working principle of this embodiment is as follows:

[0078] (1) When it is necessary to pull out the pull-out basket 2 located below:

[0079] 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;

[0080] First, pull the pull rod 42 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;

[0081] Then, the pull rod 42 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 7 In the working position shown in FIG. 1 , the support bar 33 is arranged vertically, and the bottom end of the locking rod 41 is directly opposite to the locking hole 312, so that the locking rod 41 is inserted into the locking hole 312 under the action of its own gravity to be locked. At the same time, Figure 8As shown, when the pull-out basket 2 is arranged substantially horizontally, the head of the limiting pin 51 is directly opposite to the limiting hole 3311, so that the limiting pin 51 extends outward under the elastic force of the elastic member 52 and is inserted into the limiting hole 3311 for locking. At this time, the pull rod 42 is released, and the pull-out basket 2 is still stably maintained in a horizontal state. At this time, the user can take and put tableware without bending over;

[0082] (2) When the pull-out basket 2 located below needs to be pushed back:

[0083] It is only necessary to pull the handle 44 forward first, so that the lock rod 41 moves upward and disengages from the lock hole 312 under the pull of the first pull rope 43 to unlock the lock. At the same time, the pull basket 2 is slightly lifted to move the limit pin 51 upward, and the guide slope 511 thereof abuts against the shaft sleeve 331. The gear pin 51 shrinks inward under the pressure of the shaft sleeve 331 and disengages from the limit hole 3311 to unlock the lock.

[0084] Then, the pull rod 42 is pushed backward, and 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 middle position shown, at this time the pulley 21 contacts the slide rail 13; during this process, the damping spring 62 will give the pull-out basket 2 a damping effect, making it move smoothly;

[0085] Then, the pull rod 42 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.

[0086] Embodiment 2:

[0087] like Fig.10 The second preferred embodiment of the pull-out basket cabinet of the present invention is shown in FIG. The difference from the first embodiment is that:

[0088] In this embodiment, the two lifting assemblies 3 are not arranged symmetrically, and the second locking assembly 5 is not provided. Fig.10 As shown, in the two sets of lifting components 3, the rotation axes between the support bars 33 and the fixing frames 32 are on the same horizontal plane and are arranged at intervals in the front-to-back direction. That is to say, 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. Compared with the second locking assembly 5, this design can not only keep the pull-out basket 2 in a horizontal state in the working position, but also keep the pull-out basket 2 in a horizontal state during the rotation of the support bars 33.
