Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a cleaning machine for cleaning tableware, fruits and vegetables. Background Technology

[0002] As people's living standards continue to improve, dishwashers, as a type of kitchen appliance, are increasingly entering households.

[0003] Dishwashers typically use a dish rack to hold the dishes, and a spray arm sprays water to clean the dishes in the rack. The rack is manually pulled out and retracted by the customer, which is inconvenient. To improve this, Chinese patent ZL 200580048985.4, "Dishwasher Including Storage Container," discloses a solution that includes a processing chamber and a storage container. The storage container is equipped with at least one drive device for driving the container. The drive device is designed to cause the storage container to move out of and / or into the processing chamber. The drive device is a motor, equipped with an actuation device that drives the storage container. The actuation device is a gear that meshes with a rack mounted on the storage container.

[0004] The above solution uses the linkage of a motor and a gear rack to automatically pull out and retract the dish rack, providing convenience for users. However, since the gears and racks are located in the washing chamber, water or residue can easily accumulate, leading to secondary contamination during subsequent washing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cleaning machine that can discharge slag and water in a timely manner to avoid secondary pollution, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A washing machine includes an inner tank, a dish basket, and a drive mechanism. The inner tank has an opening at its front side, and the drive mechanism is used to drive the dish basket into and / or out of the inner tank through the opening. The surface of the drive mechanism is provided with a guide structure for guiding splashed water and / or residue into the inner tank.

[0008] The aforementioned flow guiding structure can promptly remove water and slag that adhere to the surface of the drive mechanism during the cleaning process, preventing water and slag from accumulating on the surface of the drive mechanism and thus avoiding secondary pollution during subsequent cleaning.

[0009] Preferably, the drive mechanism includes a gear disposed on the inner wall of the inner liner and a rack disposed on the outer side of the basket, wherein the gear and rack mesh for transmission. The drive mechanism adopts a gear and rack transmission, which facilitates installation and maintenance, and has good structural adaptability.

[0010] Preferably, the upper surface of the rack forms a guide slope that gradually decreases outward from the side wall of the basket. This structure can prevent water and slag accumulation on the upper surface of the rack.

[0011] Preferably, the inner wall of the inner liner is provided with a protective box that surrounds at least part of the gears, and the bottom of the protective box has a first water guide and / or slag guide opening. The protective box can protect the gears and prevent residue from remaining on the gear teeth, and the first water guide and / or slag guide opening allows water and slag in the protective box to be discharged in a timely manner.

[0012] Preferably, the teeth of the rack are arranged downwards and mesh with the top of the gear, the protective box is located below the rack and surrounds part of the gear therein, and the top of the protective box has an opening for the top of the gear to be exposed. This structure facilitates the protection of the gear by the protective box and avoids interference with the rack.

[0013] Preferably, the gap between the top of the protective box and the bottom of the rack creates a safe distance of 1-5 mm to prevent a person's hand from getting stuck. This structure can prevent the risk of a user's fingers getting pinched.

[0014] Preferably, the drive mechanism further includes a guide rail assembly that allows the side of the bowl basket to slide against the side wall of the inner liner. The guide rail assembly has a second water and / or slag outlet facing the side wall of the bowl basket. The guide rail assembly allows the bowl basket to move more smoothly when entering and exiting, and the second water and / or slag outlet on the side wall of the guide rail assembly prevents water and slag residue from remaining in the guide rail assembly.

[0015] Preferably, the guide rail assembly includes a first part, a second part, and a third part extending along the front-rear direction of the inner liner. The first part is constrained to the inner wall of the inner liner, the second part is slidably constrained within the first part, and the third part is slidably constrained within the second part with its outer surface connected to the basket. The second water guide and / or slag guide opening is located on the third part. This three-section guide rail assembly structure achieves smoother sliding. Ball bearings are provided between the various parts of the three-section guide rail assembly to increase sliding smoothness. The specific structure of the three-section guide rail assembly is prior art and will not be described in detail here. While the three-section guide rail assembly slides smoothly, water can easily accumulate in the gaps between the parts. The aforementioned second water guide and / or slag guide opening allows for timely drainage of internal water.

[0016] Preferably, there are multiple second water and / or slag guide ports, spaced apart along the length of the third portion. Because the guide rail assembly has a large front-to-back length, multiple second water and / or slag guide ports are provided to ensure timely drainage from various points on the guide rail assembly.

[0017] Compared with the prior art, the advantages of this utility model are as follows: the drive mechanism of this utility model can drive the bowl basket to move in and out automatically, which is convenient to use; a guide structure is provided on the surface of the drive mechanism to guide the splashed water and / or residue into the inner liner, which can promptly drain the water and residue that are stuck to the surface of the drive mechanism during the washing process, avoid the accumulation of water and residue on the surface of the drive mechanism, and thus avoid secondary pollution during the second washing.
