Description

Technical Field

[0001] This utility model relates to a kitchen appliance. Background Technology

[0002] Kitchen appliances such as dishwashers and sterilizers have dish racks inside their cabinets to place tableware on for washing or sterilization. To make it easy to take out and put away tableware, the dish racks need to be pull-out and installed inside the cabinet.

[0003] For example, the Chinese utility model patent disclosed in patent application number CN202320415757.1 (publication number CN219680562U) entitled "Dish Basket Assembly for Washing Machine and Washing Machine" includes a dish basket assembly comprising a first dish basket frame; a second dish basket frame located below the first dish basket frame; a guide rail disposed on the side of the first dish basket frame, the guide rail extending in a front-rear direction; a sliding part disposed on the first dish basket frame, the sliding part being connected to or in contact with the top of the guide rail, and the sliding part being able to generate relative displacement with the guide rail; and a connecting part disposed on the second dish basket frame, the connecting part being connected to the lower part of the guide rail, the connecting part also being able to generate relative displacement with the guide rail.

[0004] Current dish racks usually require manual pushing and pulling, which is inconvenient, especially when there are many dishes on the rack, making pushing and pulling quite strenuous. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a kitchen appliance with an automatically sliding dish rack, which is in line with the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a kitchen appliance, including...

[0007] The box-shaped structure has an open front.

[0008] A bowl basket is installed in the box and can move back and forth. The bowl basket can enter and exit the box through the opening of the box.

[0009] Its characteristic is that it also includes

[0010] The drive mechanism, located on the left and right sides of the bowl basket, includes...

[0011] Drive components;

[0012] The toothed belt is ring-shaped and extends in the front-to-back direction, with multiple teeth arranged sequentially on its inner wall surface along its extension direction.

[0013] There are two gears located at the front and rear ends of a toothed belt, respectively. The gears mesh with the toothed belt, and the rotation axis of the gears extends in the left-right direction. At least one of the gears is driven by a driving component.

[0014] A connecting rod extends in the left-right direction and is fixedly connected to the toothed belt. The connecting rod is always located above or below the annular area of ​​the toothed belt.

[0015] The connecting rod can take many forms. Preferably, the bowl basket is a hollow structure composed of multiple frame strips, with one frame strip extending laterally toward the toothed belt to form the connecting rod. This structural form of the connecting rod is simple and integrally connected to the bowl basket, resulting in good connection stability.

[0016] Preferably, the connecting rod is detachably threaded onto the toothed belt. This way, if the drive mechanism malfunctions, only the drive mechanism needs to be replaced, preventing the basket from being rendered unusable.

[0017] To prevent the connecting rod from detaching from the toothed belt, preferably, the free end of the connecting rod extends out of the toothed belt, and the free end of the connecting rod is provided with a threaded portion, on which a nut is threadedly connected to abut against the wall of the toothed belt facing away from the basket. The nut serves to position the connecting rod.

[0018] To prevent excessive movement of the toothed belt from affecting the forward and backward movement of the bowl basket, a micro switch is provided in the housing. The toothed belt is provided with a first contact and a second trigger at intervals along the forward and backward direction, which can selectively trigger the micro switch. When the first trigger triggers the micro switch, the bowl basket moves to the forward limit position. When the second trigger triggers the micro switch, the bowl basket moves to the rear limit position.

[0019] Preferably, guide rails are fixedly provided on both the left and right sides of the bowl basket in the housing. The guide rails extend in the front-to-back direction, and guide members that can slide along the guide rails are provided on both the left and right sides of the bowl basket. The guide rails not only guide the movement trajectory of the bowl basket, but also position the bowl basket vertically to ensure that the bowl basket moves smoothly when moving back and forth.

[0020] Preferably, the drive mechanism is one set, or the drive mechanism is two sets located on the left and right sides of the bowl basket respectively, so that the bowl basket is subjected to more even force and moves smoothly.

[0021] In the above solution, the kitchen appliance is a dishwasher.

[0022] Compared with the prior art, the advantages of this utility model are: by setting a driving mechanism, when the driving component is working, the driving gear rotates, thereby driving the toothed belt to move. Since the toothed belt is connected to the bowl basket through a connecting rod, the bowl basket will be driven by the driving mechanism to move back and forth automatically, so there is no need to push or pull manually, which saves more effort.

[0032] like Figures 1-6 As shown, the kitchen appliance of this preferred embodiment includes a housing 1, a dish rack 2, a drive mechanism 3, and a guide rail 4.

[0033] The front of the container 1 is open, and the bowl basket 2 is movable back and forth inside the container 1. The bowl basket 2 can enter and exit the container 1 through the open opening. Guide rails 4 are fixedly installed on both the left and right sides of the bowl basket 2 inside the container 1. The guide rails 4 extend in the back and forth direction, and guide members 21 that can slide along the guide rails 4 are provided on both the left and right sides of the bowl basket 2. The guide rails 4 not only guide the movement trajectory of the bowl basket 2, but also position the bowl basket 2 vertically to ensure that the bowl basket 2 is stable when moving back and forth.

[0034] The above are all existing technologies and will not be elaborated further here.

[0035] The drive mechanism 3 is located on the left and right sides of the bowl basket 2. In this embodiment, there is one set of drive mechanisms 3. Of course, there can also be two sets of drive mechanisms 3 located on the left and right sides of the bowl basket 2 respectively. In this way, the bowl basket 2 is subjected to more even force and moves smoothly.

[0036] The drive mechanism 3 includes a drive component 31, a toothed belt 32, a gear 33, and a connecting rod 34.

[0037] The driving component 31 can be a motor. The toothed belt 32 is ring-shaped and extends in the front-back direction. Multiple teeth 321 are arranged sequentially on its inner wall along its extension direction. There are two gears 33 located at the front and rear ends of the toothed belt 32 respectively. The gears 33 mesh with the toothed belt 32. The rotation axis of the gears 33 extends in the left-right direction. One of the gears 33 is connected to the driving component 31 for driving.

[0038] The connecting rod 34 extends in the left-right direction and is fixedly connected to the toothed belt 32. The connecting rod 34 is always located above or below the annular area 322 of the toothed belt 32. In this embodiment, the basket 2 is a hollow structure composed of multiple frame strips, one of which extends towards the toothed belt 32 in the left-right direction to form the connecting rod 34. This structural form of the connecting rod 34 is simple and integrally connected to the basket 2, resulting in good connection stability.

[0039] When the drive unit 31 is working, the drive gear 33 rotates, thereby driving the toothed belt 32 to move. Since the toothed belt 32 is connected to the basket 2 through the connecting rod 34, the basket 2 will be driven by the drive mechanism 3 to move back and forth automatically, so there is no need to push or pull manually, which saves effort.

[0040] Preferably, the connecting rod 34 is detachably mounted on the toothed belt 32. This way, if the drive mechanism 3 fails, only the drive mechanism 3 needs to be replaced, preventing the basket 2 from being rendered unusable. The free end of the connecting rod 34 extends out of the toothed belt 32 and has a threaded portion. A nut 35 is threaded onto the threaded portion, abutting against the wall of the toothed belt 32 facing away from the basket 2. The nut 35 serves to position the connecting rod 34, preventing it from detaching from the toothed belt 32.

[0041] To prevent the toothed belt 32 from moving excessively and affecting the forward and backward movement of the basket 2, a micro switch 6 is provided in the housing 1. The toothed belt 32 is provided with a first contact and a second trigger at intervals along the forward and backward direction, which can selectively trigger the micro switch 6. When the first trigger triggers the micro switch 6, the basket 2 moves to the forward limit position. When the second trigger triggers the micro switch 6, the basket 2 moves to the rear limit position.

[0042] The kitchen appliance in this embodiment is a dishwasher; of course, it could also be a sterilizer.
