Description

Technical Field

[0001] The utility model relates to the technical field of dishwasher sinks, in particular to a dishwasher sink structure. Background Art

[0002] With the advancement of technology and the improvement of living standards, especially the rapid development of home appliances, specialized dishwashing equipment has emerged for cleaning dishes. A multifunctional dishwasher typically features spraying, drying, and sterilizing functions. Users simply place dishes and other tableware into the dishwasher, which automatically completes a series of cleaning tasks based on user settings. Its ease of use and fully automated operation effectively reduces user effort, making dishwashers increasingly popular among users.

[0003] Dishwashers currently on the market generally use a spray-rinsing method to clean dishes. To effectively utilize the water flow, the dishwasher is equipped with an internal circulating water system. This circulating water system is equipped with corresponding water collection and filtering structures in the washing chamber of the inner tank to effectively filter the flushing water flow before it is recycled. Specifically, the structure includes a sink, a spray arm seat is provided on the sink, which is used to connect the spray arm, and a water collection tank connected to the water pump inside the base. The water collection tank is equipped with a filter. The filter effectively filters food residue in the water and then outputs it under the pressure of the water pump for a new round of spray rinsing. In actual practice, after the spray arm sprays, some water flow tends to remain on the side of the spray arm seat. Over time, the water flow easily penetrates from the connection between the spray arm and the spray arm seat, thereby dripping into the interior of the dishwasher.

[0004] Therefore, a dishwasher sink structure is proposed to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide a water tank structure of a dishwasher, which can effectively avoid water retention on the surface of the guide surface and improve the guide effect.

[0006] The technical solution adopted by the utility model to solve the problem is: a sink structure of a dishwasher, including a sink body with an upper opening, the sink body including a guide platform and a water collection trough which is recessed downward and connected to the guide platform, a spray arm seat is installed on the guide platform, and a filtering device is installed on the water collection trough, the guide platform includes an inclined surface gradually inclined toward the water collection trough and a boss arranged on the inclined surface, the top surface of the boss is higher than the inclined surface, and the spray arm seat is installed on the boss; a guide rib is provided on the inclined surface, a guide channel is formed between the guide rib and the boss, and the guide channel is communicated with the water collection trough.

[0007] As a further improvement of the above technical solution, the guide rib includes a first guide rib located on the left side of the boss, and a first guide channel is formed between the first guide rib and the boss; the guide rib also includes a second guide rib surrounding the first guide rib and the boss, and a second guide channel is formed between the second guide rib and the first guide rib, and the second guide channel is connected to the first guide channel and the water collection trough.

[0008] As a further improvement of the above technical solution, the first guide rib and the second guide rib are U-shaped when viewed from above.

[0009] As a further improvement of the above technical solution, the surfaces of the first guide rib and the second guide rib are both inclined toward the water collection trough.

[0010] As a further improvement of the above technical solution, a third guide channel is formed between the second guide rib and the inner side wall of the water trough body, and the third guide channel is connected to the water collection trough.

[0011] As a further improvement of the above technical solution, the filtering device includes a water cup and a filter screen, the filter screen is fixedly arranged on the top of the water pump, the filter screen is located in the water collection tank, the water cup is located at the bottom of the water collection tank, and a waterproof rubber ring is arranged between the water cup and the filter screen.

[0012] As a further improvement of the above technical solution, a groove is provided on the top edge of the water cup, and a protrusion is provided on the bottom of the waterproof rubber ring, and the protrusion is snap-connected to the groove.

[0013] The beneficial effects of the present utility model are as follows: the spray arm seat is used to connect the nozzle and the water pump. When in use, the water pump provides water to the nozzle and cleans the tableware. The water used to clean the tableware will flow to the water collection trough through the inclined surface. Since the table top of the boss is higher than the inclined surface, and a diversion channel is formed between the guide rib and the boss, the water can flow to the water collection trough through the diversion channel and will not accumulate at the spray arm seat, thereby improving the diversion effect and effectively preventing water from leaking from the spray arm seat.
