Description

Technical Field

[0001] The utility model relates to a dishwasher. Background Art

[0002] For a large number of built-in dishwashers, in order to improve the utilization rate of the inner space of the dishwasher, the "chopstick cage area" is usually extracted separately, and an upper bowl basket rack is added to meet its loading needs. The upper bowl basket rack is placed on the top layer of the inner cavity of the dishwasher. The space of the upper bowl basket rack is relatively flat, and knives, forks, chopsticks, spoons, forks, soup spoons, etc. are placed on this layer. In this way, the space of the middle bowl basket rack and the lower bowl basket rack can be fully utilized for loading dishes, etc.

[0003] For example, the Chinese utility model patent with patent number CN201820735300.8 (publication number CN208926295U) discloses "bowl basket assembly and dishwasher", in which the bowl basket assembly 100 includes three layers of bowl basket racks, namely a lower bowl basket rack 10, a middle bowl basket rack 20 and an upper bowl basket rack 30, and the upper bowl basket rack 30 is detachably fixed to the middle bowl basket rack 20. Both the lower bowl basket rack 10 and the middle bowl basket rack 20 can be pulled out and installed on the body of the dishwasher.

[0004] This patent fixes the upper bowl basket rack on the middle bowl basket rack, so that the upper bowl basket rack can move synchronously when the middle bowl basket rack is pulled out. However, the two bowl basket racks always move synchronously. When tableware only needs to be placed on one of the bowl basket racks, the other bowl basket rack will also be pulled out, which is not only heavy but also inconvenient. In addition, the upper bowl basket rack is always blocked above the middle bowl basket rack, and the space above the middle bowl basket rack is relatively cramped, making it inconvenient to take tableware into and put it in the middle bowl basket rack.

[0005] Alternatively, as shown in the Chinese utility model patent No. CN202221811490.X (publication No. CN217792946U) disclosed in the "A Deodorizing Dishwasher", three sets of guide rail mechanisms are respectively provided for the three bowl rack bodies, so that each bowl rack body can move independently, but there are many parts involved, and each bowl rack body needs to be pushed and pulled one by one, which is also more troublesome. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a dishwasher with two bowl baskets that can move synchronously and relatively independently in view of the current status of the prior art.

[0007] The utility model solves the above technical problems by adopting the following technical solution: a dishwasher comprising

[0008] Box, open front;

[0009] The upper bowl basket can be moved forward and backward from the opening of the box body into and out of the box body;

[0010] A first guide rail is provided in the box body, and the first guide rail extends in a front-to-back direction and is used to guide the upper bowl basket;

[0011] The lower bowl basket is located below the upper bowl basket, and the lower bowl basket can move forward and backward from the opening of the box body into and out of the box body;

[0012] A second guide rail is provided in the box body, and the second guide rail extends in the front-rear direction and is used to guide the lower bowl basket;

[0013] It is characterized by that it also includes

[0014] A third guide rail is provided on the top of the lower bowl basket and extends in the front-to-back direction;

[0015] The slide groove is arranged at the bottom of the upper bowl basket, and the slide groove and the third guide rail can move synchronously or slide in cooperation in the front-rear direction.

[0016] Preferably, the bottom of the chute is open, and the upper basket is placed on the third guide rail, so that the upper basket can be removed from the third guide rail and used as a drain basket; or when the upper basket and the lower basket are not needed at the same time, the upper basket can also be removed.

[0017] The third guide rail can have a variety of structural forms. Preferably, the third guide rail is an upper rib connected to the lower bowl basket, and the upper rib extends in the front-to-back direction and can be inserted into the slide groove. The structure of the third guide rail is simple.

[0018] In order to prevent the upper bowl basket from escaping from the third guide rail, a limiting portion is provided at the front end of the upper rib, and the limiting portion can abut against the front end of the slide groove, and the upper bowl basket cannot continue to move forward.

[0019] The first guide rail can have a variety of structural forms. Preferably, a convex portion extending in the front-to-back direction is provided on the side wall of the box body, and the top wall surface of the convex portion is the first guide rail, and the upper bowl basket can be partially placed on the first guide rail. The first guide rail has a simple structure and is directly formed on the box body.

[0020] In order to facilitate the upper basket and the lower basket to move independently of each other, the dishwasher further includes an elastic member acting on the upper basket, and the upper basket maintains an upward movement tendency under the action of the elastic member, so that when the weight of the upper basket and the tableware it carries is less than the elastic force of the elastic member, the chute is disengaged from the third guide rail. When the upper basket carries tableware, and the total weight of the upper basket and the tableware exceeds the elastic force of the elastic member, the upper basket and the lower basket can be pulled out synchronously, which is convenient to operate; when the upper basket does not carry tableware, or the total weight of the upper basket and the tableware is less than the elastic force of the elastic member, the upper basket will move upward under the action of the elastic member so that the chute is disengaged from the third guide rail, and the upper basket and the lower basket can move independently at this time; or, when it is necessary to take and place tableware on the lower basket, the chute can be disengaged from the third guide rail, and the upper basket can be pushed back into the cabinet to free up space above the lower basket.

[0021] The upper bowl basket is provided with a receiving groove with an open bottom, a moving rod is inserted in the receiving groove, and the upper bowl basket can move up and down relative to the moving rod. The elastic member is a vertically extending spring, the upper end of the spring abuts against the top wall of the receiving groove, and the lower end of the spring abuts against the moving rod. The moving rod can be placed on the first guide rail and move forward and backward relative to the first guide rail.

[0022] In order to prevent the friction resistance between the moving rod and the first guide rail from being too large, so that the upper basket cannot move synchronously when the lower basket is pushed or pulled, the moving rod has two spaced apart in the front-to-back direction, and each moving rod has a stopper on its outer wall surface. The two stops are respectively referred to as a front stopper and a rear stopper located behind the front stopper according to their orientations. A front stopper and a rear stopper are sequentially provided on the lower basket in the front-to-back direction, the front stopper is located at the rear side of the front stopper and the two can abut against each other, and the rear stopper is located at the front side of the rear stopper and the two can abut against each other. When the lower basket is pulled forward, the front stopper abuts against the front stopper, pushing the upper basket to move synchronously; when the lower basket is pushed backward, the rear stopper abuts against the rear stopper, pushing the rear basket to move synchronously; in addition, when the slideway is out of contact with the third guide rail, the front stopper is located above the front stopper, and the rear stopper is located above the rear stopper, which will not affect the independent movement of the upper basket.

[0023] In order to prevent the moving rod from escaping from the accommodating groove, a limiting groove is provided on the upper bowl basket at a position corresponding to the peripheral wall of the accommodating groove, the limiting groove is communicated with the accommodating groove, the limiting groove extends vertically, and a limiting block that can slide along the limiting groove is provided on the moving rod. The limiting block cooperates with the limiting groove to guide the up and down movement trajectory of the moving rod and limit the up and down movement stroke of the moving rod to prevent the moving rod from escaping from the accommodating groove.

[0024] In order to facilitate the limiting block to enter the limiting groove, the upper bowl basket is further provided with a strip groove at a position corresponding to the peripheral wall of the accommodating groove, the strip groove extends vertically, the lower end of the strip groove passes through the bottom of the upper bowl basket, and the upper end of the strip groove is connected to the lower end of the limiting groove through the connecting groove. In this way, the limiting block can enter the limiting groove from the strip groove.

[0025] Compared with the prior art, the utility model has the following advantages: the utility model provides a third guide rail on the lower bowl basket and a slide groove on the upper bowl basket, the slide groove and the third guide rail can slide together or move synchronously, the upper bowl basket is pressed against the lower bowl basket under the action of gravity, and the upper bowl basket and the lower bowl basket can move synchronously; if the upper bowl basket and the lower bowl basket do not need to move synchronously, the upper bowl basket can be manually pushed back into the box body, and the lower bowl basket moves alone, which is convenient for taking and placing tableware on the lower bowl basket.

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] Example 1

[0035] like Figures 1 to 3 As shown, the dishwasher of this preferred embodiment includes a cabinet 1, an upper basket 2, a first guide rail 11, a lower basket 3, a second guide rail 12, a third guide rail and a slide groove 21.

[0036] The front side of the box body 1 is open, and the upper bowl basket 2 and the lower bowl basket 3 can move forward and backward from the open part of the box body 1 to enter and exit the box body 1, and the lower bowl basket 3 is located below the upper bowl basket 2.

[0037] The first guide rail 11 extends in the front-to-back direction and is disposed in the box body 1. The first guide rail 11 is used to guide the upper bowl basket 2. In this embodiment, a convex portion 10 extending in the front-to-back direction is disposed on the side wall of the box body 1. The top wall surface of the convex portion 10 is the first guide rail 11, and a part of the upper bowl basket 2 can be placed on the first guide rail 11.

[0038] The second guide rail 12 extends in the front-to-back direction and is disposed in the box body 1. The second guide rail 12 is used to guide the lower basket 3. The second guide rail 12 cooperates with the roller 31 on the lower basket 3. The cooperation method of the two can adopt the existing technology and will not be repeated here.

[0039] The third guide rail is arranged on the top of the lower basket 3 and extends in the front-to-back direction. A slide groove 21 is arranged at the bottom of the upper basket 2, and the bottom of the slide groove 21 is open. The upper basket 2 is placed on the third guide rail, and the slide groove 21 and the third guide rail can move synchronously or slide in the front-to-back direction.

[0040] The third guide rail is an upper rib 32 connected to the lower basket 3, the upper rib 32 extends in the front-to-back direction and can be inserted into the slide groove 21. A lower rib 33 located below the upper rib 32 is fixedly mounted on the lower basket 3, the lower rib 33 extends in the front-to-back direction, and the rear ends of the upper rib 32 and the lower rib 33 are connected by a connecting rib 34.

[0041] The upper basket 2 is pressed against the lower basket 3 under the action of gravity, and the upper basket 2 and the lower basket 3 can move synchronously; if the upper basket 2 and the lower basket 3 do not need to move synchronously, the upper basket 2 can be manually pushed back into the box 1, and the lower basket 3 moves independently, so as to facilitate the taking and placing of tableware on the lower basket 3. In addition, the upper basket 2 can be removed from the third guide rail and used as a drain basket; or when the upper basket 2 and the lower basket 3 do not need to be used at the same time, the upper basket 2 can also be removed.

[0042] A limiting portion 35 is provided at the front end of the upper rib 32, and the limiting portion 35 can abut against the front end of the slide groove 21, and at this time, the upper basket 2 cannot move forward further.

[0043] Example 2

[0044] like Figures 4 to 7 As shown, the difference between this embodiment and embodiment 1 is that this embodiment is further provided with an elastic member 4 and a moving rod 5.

[0045] The upper basket 2 keeps moving upward under the action of the elastic member 4, so that when the weight of the upper basket 2 and the tableware it carries is less than the elastic force of the elastic member 4, the upper basket 2 moves upward and the slide groove 21 is out of contact with the third guide rail.

[0046] The upper basket 2 is provided with a receiving groove 22 with an open bottom, and a moving rod 5 is inserted in the receiving groove 22. The upper basket 2 can move up and down relative to the moving rod 5. The elastic member 4 is a spring extending vertically. The upper end of the spring abuts against the top wall of the receiving groove 22, and the lower end of the spring abuts against the moving rod 5. The moving rod 5 can be placed on the first guide rail 11 and move forward and backward relative to the first guide rail 11.

[0047] In order to prevent the friction resistance between the moving rod 5 and the first guide rail 11 from being large, so that the upper basket 2 cannot move synchronously when the lower basket 3 is pushed or pulled, the moving rod 5 has two spaced apart along the front-to-back direction, and a stopper is provided on the outer wall surface of each moving rod 5. The two stops are respectively referred to as a front stopper 51 and a rear stopper 52 located behind the front stopper 51 according to their orientations. A front stopper 36 and a rear stopper 37 are sequentially provided along the front-to-back direction on the lower basket 3. The front stopper 36 is located at the rear side of the front stopper 51 and the two can abut against each other. The rear stopper 37 is located at the front side of the rear stopper 52 and the two can abut against each other.

[0048] When the lower basket 3 is pulled forward, the front stopper 36 abuts against the front stopper 51, pushing the upper basket 2 to move synchronously; when the lower basket 3 is pushed backward, the rear stopper 37 abuts against the rear stopper 52, pushing the upper basket 2 to move synchronously; in addition, when the slide groove 21 is out of contact with the third guide rail, the front stopper 51 is located above the front stopper 36, and the rear stopper 52 is located above the rear stopper 37, which will not affect the independent movement of the upper basket 2.

[0049] In order to prevent the moving rod 5 from escaping from the accommodating groove 22, a limiting groove 23 is provided on the upper bowl basket 2 at a position corresponding to the peripheral wall of the accommodating groove 22. The limiting groove 23 is communicated with the accommodating groove 22 and extends vertically. A limiting block 53 that can slide along the limiting groove 23 is provided on the moving rod 5. The limiting block 53 cooperates with the limiting groove 23 to guide the up and down movement trajectory of the moving rod 5 and limit the up and down movement stroke of the moving rod 5 to prevent the moving rod 5 from escaping from the accommodating groove 22.

[0050] In addition, a strip groove 24 is provided on the upper basket 2 at a position corresponding to the peripheral wall of the accommodating groove 22. The strip groove 24 extends vertically, and the lower end of the strip groove 24 passes through the bottom of the upper basket 2. The upper end of the strip groove 24 is connected to the lower end of the limiting groove 23 through the connecting groove 25. In this way, the limiting block 53 can enter the limiting groove 23 from the strip groove 24.

[0051] When tableware is carried on the upper basket 2, and the total weight of the upper basket 2 and the tableware exceeds the elastic force of the elastic member 4, the upper basket 2 is pressed against the third guide rail, and the upper basket 2 and the lower basket 3 can be pulled out synchronously, which is convenient to operate; when there is no tableware on the upper basket 2, or the total weight of the upper basket 2 and the tableware is less than the elastic force of the elastic member 4, the upper basket 2 will move upward under the action of the elastic member 4 so that the slide groove 21 and the third guide rail are out of contact, and the upper basket 2 and the lower basket 3 can move independently at this time; or, when it is necessary to take or place tableware on the lower basket 3, the slide groove 21 and the third guide rail can be out of contact, and the upper basket 2 can be pushed back into the box body 1 to free up space above the lower basket 3.

[0052] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
