Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers capable of cleaning tableware and / or fruits and vegetables, and particularly relates to a bowl basket assembly for a dishwasher and a dishwasher. Background Art

[0002] A dishwasher for cleaning tableware and / or fruits and vegetables is a widely popular household appliance. It uses a spray arm to eject high-pressure water jets while the spray arm rotates to achieve the rinsing of the surface of tableware. The dishwasher is also equipped with a bowl basket for carrying tableware and fixing the position of tableware during the washing and drying processes. With the increasing market requirements for the washing rate and drying rate of dishwashers, the requirements for the convenience and flexibility of using the bowl basket are also getting higher and higher. In order to be able to hold a relatively large number of tableware, at least two bowl baskets are usually provided. And in order to facilitate the access to tableware in the lower bowl basket, usually the upper bowl basket can move downward relative to the lower bowl basket.

[0003] As disclosed in the Chinese utility model patent "Bowl Rack Assembly for Dishwasher and Dishwasher" with the patent number CN202320220163.5 (publication number CN219538221U), the bowl rack assembly includes a first bowl rack; a second bowl rack located above the first bowl rack, and the second bowl rack is connected to the first bowl rack through a connection structure; the connection structure can produce a height change in the up and down direction, so that the second bowl rack can move up and down relative to the first bowl rack. When it is necessary to place or take out tableware on the first bowl rack, the second bowl rack is raised so that the space above the first bowl rack is relatively spacious, facilitating the placement and removal of tableware on the first bowl rack; after the tableware on the first bowl rack is placed or taken out, the second bowl rack is lowered so that the overall height of the bowl rack assembly is moderate. Otherwise, if the overall height of the bowl rack assembly is too high, it will occupy too much space in the washing cavity of the cabinet, making it inconvenient to set other components in the washing cavity. The connection structure includes two connecting rods arranged crosswise. The lower ends of the two connecting rods are spaced apart in the front and rear directions, and the lower ends of the two connecting rods are both rotatably connected to the first bowl rack through a rotating shaft extending in the left and right directions. The upper ends of the two connecting rods are both installed on the second bowl rack and can move in the front and rear directions.

[0004] In this form of connection structure, the rising amplitude of the second bowl rack (i.e., the upper bowl basket) is small, and it is still inconvenient to place or take out tableware in the first bowl rack (i.e., the lower bowl basket). Especially for a dishwasher with an open top, if the rising amplitude of the second bowl rack is too small, after rising to the upper limit position, it may still be located in the tank of the dishwasher, blocking the first bowl rack and making it impossible to place or take out tableware on the first bowl rack;

[0005] In addition, the entire connecting structure is located at the top of the first bowl rack. Even when the connecting structure is in a folded state, it still has a certain height. And the second bowl rack is located above the connecting structure, that is, the connecting structure occupies a certain space vertically, resulting in the entire bowl rack assembly occupying a relatively large vertical space and having relatively high requirements for the vertical space of the tank of the dishwasher. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a bowl rack assembly for a dishwasher with a large upward movement amplitude of the upper bowl basket in view of the current situation of the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a dishwasher applying the above bowl rack assembly in view of the current situation of the prior art.

[0008] The technical solution adopted by the present invention to solve the above first technical problem is: A bowl rack assembly for a dishwasher, comprising

[0009] A lower bowl basket with an open top;

[0010] An upper bowl basket located above the lower bowl basket, the upper bowl basket can be in a first position and a second position, and the height of the upper bowl basket in the second position is higher than the height of the upper bowl basket in the first position;

[0011] Two sets of connecting structures are respectively arranged on the left and right sides of the upper bowl basket, and each connecting structure includes a first rotating rod and a second rotating rod arranged in a cross manner;

[0012] It is characterized in that the first end of the first rotating rod is rotatably installed on the lower bowl basket through a pin shaft extending in the left-right direction, the second end of the first rotating rod is provided with a first sliding portion, and the first sliding portion is slidably installed on a first guide rail, and the first guide rail extends in the front-rear direction and is connected to the upper bowl basket;

[0013] The second rotating rod includes a first rod body and a second rod body. The first end of the first rod body is provided with a second sliding portion, and the second sliding portion is slidably installed on a second guide rail. The second guide rail extends in the front-rear direction and is fixedly installed on the lower bowl basket. The second guide rail and the pin shaft are spaced apart in the front-rear direction. The second end of the first rod body is rotatably connected to the middle part of the first rotating rod, and the rotation axis of the first rod body extends around the left-right direction;

[0014] The first end of the second rod body is rotatably connected to an installation block, the installation block is connected to the upper bowl basket, the second end of the second rod body is rotatably connected to the middle part of the first rotating rod, the rotation axis of the second end of the first rod body coincides with the rotation axis of the second end of the second rod body, and the first rod body and the second rod body are always in the same straight line, and the rotation axes at both ends of the second rod body both extend in the left-right direction.

[0015] In order to facilitate the taking and placing of tableware in the bowl basket, the second guide rail is located at the rear side of the pin shaft, and the second guide rail is inclined downward from the back to the front, and the first section of the first rotating rod is located on the extension line of the second guide rail. In this way, when the upper bowl basket moves to the second position, it is not only raised in the vertical direction, but also moves backward a certain distance in the horizontal direction, staggering the space directly above the lower bowl basket, which further facilitates the taking and placing of tableware in the bowl basket.

[0016] In order to further increase the vertical distance between the upper basket and the lower basket when the upper basket is in the second position, the first guide rail is connected to the upper basket via a first connecting member extending vertically, and the mounting block is connected to the upper basket via a second connecting member extending vertically. The first connecting member and the second connecting member have a certain height, which can increase the vertical distance between the upper basket and the lower basket when the upper basket is in the second position.

[0017] In order to further increase the distance that the upper basket can rise, the second guide rail and the pin are both arranged adjacent to the top of the lower basket.

[0018] In order to reduce the vertical distance between the upper basket and the lower basket when the upper basket is in the first position, the upper basket is arranged adjacent to the top of the lower basket, the first guide rail and the mounting block are arranged adjacent to the bottom of the lower basket, and the first connecting member and the second connecting member are arranged beside the lower basket. In this way, the overall structure of the basket assembly is compact, the space occupied in the vertical direction is small, and the requirements for the cavity of the washing machine are relatively low.

[0019] In order to further facilitate the taking and placing of tableware in the bowl basket, the upper bowl basket includes a frame and a drain basket, the first connecting member and the second connecting member are both connected to the frame, the frame is provided with a slide groove extending in the left-right direction and / or the front-back direction, and the bottom of the drain basket is provided with a slider that can be placed in the slide groove, and the slider can slide along the slide groove. In this way, when the upper bowl basket moves to the second position, it can also move along the first slide groove or the second slide groove to stagger the space directly above the lower bowl basket, further facilitating the taking and placing of tableware in the bowl basket, and the upper bowl basket can be moved to the top of the sink next to the trough body, and the upper bowl basket is used as a drain basket.

[0020] The pin shaft can be rotated manually, but this is relatively troublesome, so the pin shaft is drivingly connected to the driving mechanism.

[0021] Each connecting structure may be equipped with a set of driving mechanisms, but this involves more parts, so the pin shaft equipped with one of the first rotating rods is connected to the driving mechanism, and the pin shafts equipped with the two first rotating rods are connected through a linkage rod. In this way, after the pin shaft connected to the driving mechanism rotates, it will drive the two first rotating rods to rotate at the same time, that is, one set of driving mechanisms can drive two sets of connecting structures at the same time, and the structure is simplified.

[0022] The driving mechanism can have various structural forms. For example, the rotating shaft of the motor is drivingly connected to the pin shaft. Alternatively, the driving mechanism includes a driving member, a first gear drivingly connected to the driving member, and a second gear mounted on the pin shaft. The first gear and the second gear are meshed with each other, and the second gear is coaxial with the pin shaft. This design method is compact and can accurately control the rotation angle of the first rotating rod.

[0023] The technical solution adopted by the present utility model to solve the above-mentioned second technical problem is: a dishwasher applying the above-mentioned bowl basket assembly, characterized in that: it includes a trough with one side open, and in a state where the upper bowl basket is in the first position, the bowl basket assembly is arranged in the trough.

[0024] Preferably, the top of the trough is open, and a door body that can open or close it is movably arranged at the open top of the trough. The door body is located on the path when the upper bowl basket moves from the first position to the second position. In this way, the effect of a top door can be achieved. During the drying process of tableware, when the door body is opened at a certain angle, humid and hot air can be discharged, improving the drying effect. In this way, there is no need to design a top door mechanism, and the structure is streamlined.

[0025] Preferably, in a state where the upper bowl basket is in the second position, the upper bowl basket is located outside the trough, so as to facilitate taking and placing the tableware in the lower bowl basket.

[0026] Compared with the prior art, the advantages of the present utility model are: the first end of the first rotating rod of the present utility model is rotatably connected to the lower bowl basket, and the second end is slidably connected to the first guide rail;

[0027] The second rotating rod is separately designed into a first rod body and a second rod body to be respectively connected to the upper bowl basket and the lower bowl basket. With the design method of the connection structure of the present application, the rising amplitude of the upper bowl basket depends on the length of the first rotating rod and the angle that the first rotating rod can rotate. Due to the separate design of the second rotating rod, the first rotating rod can rotate a large angle, so that the upper bowl basket of the present utility model can rise by a large amplitude, leaving a large space above the lower bowl basket to facilitate taking and placing the tableware on the lower bowl basket.

[0028] Moreover, with the design form of the connection structure of the present utility model, using the parallelogram rule, the upper bowl basket moves smoothly and has a unique movement trajectory.

[0029] In addition, during the movement process of the upper bowl basket moving towards the second position, certain vibrations will also be generated to shake off the water on the tableware; during the cleaning process of the dishwasher, the upper bowl basket can be switched between the first position and the second position to change the spraying angle of the tableware on the upper bowl basket, improving the cleaning effect.

[0037] The present utility model will be further described in detail below in conjunction with the embodiments with reference to the accompanying drawings.

[0038] Embodiment 1

[0039] As Figures 1 to 5 shown, the cleaning machine of this preferred embodiment includes a tank body (not shown in the figure) and a bowl basket assembly. One side of the tank body is open, and the bowl basket assembly is arranged in the tank body.

[0040] The bowl basket assembly includes an upper bowl basket 1, a lower bowl basket 2 and a connection structure 3. The top of the lower bowl basket 2 is open. The upper bowl basket 1 is located above the lower bowl basket 2. The upper bowl basket 1 can be in a first position and a second position. The height of the upper bowl basket 1 in the second position is higher than the height of the upper bowl basket 1 in the first position. As Figure 5 shown, during the cleaning or drying process, the upper bowl basket 1 can be in the first position to reduce the overall occupied space of the bowl basket assembly; as Figure 1 shown, when it is necessary to take the tableware on the lower bowl basket 2, the upper bowl basket 1 can be in the second position to facilitate taking and placing the tableware on the lower bowl basket 2.

[0041] In this embodiment, the top of the tank body is open, and a door body (not shown in the figure) that can open or close it is movably arranged at the open top of the tank body. The door body is on the path of the upper bowl basket 1 moving from the first position to the second position. In this way, the effect of a top door can be achieved. During the drying process of the tableware, opening the door body at a certain angle can discharge the humid and hot air flow, improving the drying effect. In this way, there is no need to design a top door mechanism, and the structure is simplified.

[0042] In addition, when the upper basket 1 is in the second position, the upper basket 1 is located outside the tank body, so as to facilitate taking the tableware in the lower basket 2.

[0043] The upper basket 1 is switched between the first position and the second position through the connecting structure 3. There are two groups of the connecting structures 3, which are respectively arranged on the left and right sides of the upper basket 1.

[0044] Such as Figure 2 、 3 As shown, the connecting structure 3 includes a first rotating rod 31 and a second rotating rod 32 which are cross - arranged. The first end of the first rotating rod 31 is rotatably installed on the lower basket 2 through a pin shaft 311 extending in the left - right direction. The second end of the first rotating rod 31 is provided with a first sliding part 312. The first sliding part 312 is slidably installed on the first guide rail 4. The first guide rail 4 extends in the front - rear direction and is connected to the upper basket 1.

[0045] The second rotating rod 32 includes a first rod body 321 and a second rod body 322. The first end of the first rod body 321 is provided with a second sliding part 323. The second sliding part 323 is slidably installed on the second guide rail 5. The second guide rail 5 extends in the front - rear direction and is fixedly installed on the lower basket 2. The second guide rail 5 and the pin shaft 311 are arranged at intervals in the front - rear direction. The second end of the first rod body 321 is rotatably connected to the middle part of the first rotating rod 31, and the rotation axis of the first rod body 321 extends around the left - right direction.

[0046] The first end of the second rod body 322 is rotatably connected to the mounting block 6. The mounting block 6 is connected to the upper basket 1. The second end of the second rod body 322 is rotatably connected to the middle part of the first rotating rod 31. The rotation axis at the second end of the first rod body 321 coincides with the rotation axis at the second end of the second rod body 322. The first rod body 321 and the second rod body 322 are always in the same straight line, and the rotation axes at both ends of the second rod body 322 both extend along the left - right direction.

[0047] According to the parallelogram rule, in the state where the upper basket 1 is in the second position, the connecting lines of the two ends of the first rotating rod 31 and the two ends of the second rotating rod 32 form a square. This makes the movement process of the upper basket 1 stable and the movement track unique.

[0048] In this embodiment, the first guide rail 4 is connected to the upper basket 1 through a first connecting piece 11 extending vertically. The mounting block 6 is connected to the upper basket 1 through a second connecting piece 12 extending vertically. The first connecting piece 11 and the second connecting piece 12 have a certain height, which can increase the vertical distance between the upper basket 1 and the lower basket 2 when the upper basket 1 is in the second position, and further facilitate taking the tableware on the lower basket 2.

[0049] The second guide rail 5 and the pin 311 are both disposed adjacent to the top of the lower basket 2, further increasing the distance that the upper basket 1 can rise.

[0050] When the upper basket 1 is in the first position, the upper basket 1 is disposed adjacent to the top of the lower basket 2, the first guide rail 4 and the mounting block 6 are disposed adjacent to the bottom of the lower basket 2, and the first connecting member 11 and the second connecting member 12 are both located beside the lower basket 2. In this way, when the upper basket 1 is in the first position, the vertical spacing between the upper basket 1 and the lower basket 2 is small, the overall structure of the basket assembly is compact, the vertical space occupied is small, and the requirements for the cavity of the washing machine are relatively low.

[0051] Preferably, the second guide rail 5 is located at the rear side of the pin 311, and the second guide rail 5 is inclined downward from the rear to the front, and the first end of the first rotating rod 31 is located on the extension line of the second guide rail 5. In this way, when the upper basket 1 moves to the second position, it is not only vertically raised, but also moves backward a certain distance in the horizontal direction, staggering the space directly above the lower basket 2, further facilitating the removal and placement of tableware in the basket 2.

[0052] In order to rotate the first rotating rod 31 and the second rotating rod 32, the pin shaft 311 is connected to the driving mechanism. In this embodiment, the pin shaft 311 equipped with one of the first rotating rods 31 is connected to the driving mechanism, and the pin shafts 311 equipped with the two first rotating rods 31 are connected by a linkage rod 310.

[0053] In this embodiment, the driving mechanism includes a driving member (not shown in the figure), a first gear 71 drivingly connected to the driving member, and a second gear 72 installed on the pin 311. The first gear 71 and the second gear 72 are meshed with each other, and the second gear 72 is coaxial with the pin 311. The driving member can be a motor, which drives the first gear 71 to rotate, and then drives the second gear 72 to rotate, so that the pin 311 rotates synchronously. After the pin 311 drivingly connected to the driving mechanism rotates, it will drive the two first rotating rods 31 to rotate simultaneously, that is, one set of driving mechanisms can drive two sets of connecting structures 3 at the same time, and the structure is simplified.

[0054] The motor can be designed outside the tank body, and when the upper basket 1 is located at the first position, the first gear 71 and the second gear 72 are just meshed.

[0055] If no motor is provided, the first gear 71 may be connected to an existing damping mechanism to achieve the purpose of slowly rising and lowering the upper basket 1 .

[0056] In this embodiment, the teeth on the second gear 72 extend along an arc-shaped profile, and the angle of the arc-shaped profile is 60°.

[0057] Example 2
