Description

Technical Field

[0001] This utility model relates to the field of kitchen sink technology, specifically a cleaning device that can be used as a sink and can automatically clean fruits, vegetables, fish, meat and other food ingredients. Background Technology

[0002] For Chinese kitchens, due to the abundance of ingredients, the need for washing fruits, vegetables, fish, and meat is very high. Currently, people mostly use sinks to wash fruits, vegetables, fish, and meat, which is time-consuming and laborious. To solve this problem, the applicant's prior patent ZL201610632336.9, "Integrated Sink Washing Device," discloses a structure that integrates a separate fruit and vegetable washing machine next to the sink. While this provides convenience for users to wash fruits, vegetables, fish, and meat, the drainage components and the drive structure of the fruit and vegetable washing machine are all located at the bottom of the sink, which severely limits the height and volume of the washing machine and the sink, affecting the independent usable space of the sink.

[0003] Paper ZL201821326601.1, "A Sink-Type Washing Machine with Fruit and Vegetable Disposal Unit," discloses a structure that integrates a sink and a sink dishwasher, with a detachable and movable fruit and vegetable disposal unit installed within the sink. While this structure provides convenience for independently washing fruits and vegetables, the spray nozzles of the fruit and vegetable disposal unit actually utilize the same spray arm structure as the sink dishwasher. To avoid clogging this spray arm structure, the fruit and vegetable sink cannot drain water independently, making it inconvenient to use. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a cleaning device that can automatically drain water when not in a cleaning state, in light of the current state of the prior art.

[0005] The second technical problem to be solved by this utility model is to provide a cleaning device that can prevent the backflow of odors caused by the backflow of residual water in the drainage pipe, in light of the current state of the technology.

The first end of the V-shape surrounds the second opening, and the second end of the V-shape is connected to a blower. This blower provides bubbling gas to the food washing tank and facilitates control of the bubbling volume.

[0014] Preferably, the medium conveying module is further provided with a water inlet channel connected to the medium inlet. This water inlet channel has an inverted U-shaped structure and is arranged close to the lower part of the air inlet channel. The first end of the water inlet channel is connected to the downstream end of the air inlet channel, and the second end of the water inlet channel is connected to the water inlet structure. This structure facilitates the introduction of water into the food washing tank, and the water inlet and air inlet share a single medium inlet. Water in the water inlet channel can overflow into the food washing tank through the air inlet channel.

[0015] Preferably, the drain pump is located on the rear wall of the water tank. The blower is located on the rear wall of the water tank and arranged near the top of the water tank. The water inlet structure consists of a water inlet valve and a micro-nano bubble generator capable of generating micro-nano bubble water, both located on the rear wall of the water tank. The drain pump, blower, water inlet valve, and micro-nano bubble generator can be integrated into a single mounting box, facilitating integrated installation on the rear wall of the water tank, making full use of the narrow installation space on the rear side of the water tank, and improving space utilization.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This utility model has a medium conveying module that can be detachably connected to the food washing tank outside the water tank. After washing, the water in the food washing tank can be drained through the drainage channel, which is convenient to use. This utility model also has a control valve that can control whether the drain outlet and the drainage channel are connected. When the food washing tank is not draining, the control valve cuts off the drain outlet from the drainage channel to prevent water or odors in the drainage channel from flowing back into the food washing tank. When the food washing tank is draining, the control valve connects the drain outlet to the drainage channel to drain water. This structure can always maintain a good cleaning environment in the food washing tank, which is conducive to improving the user experience. Attached Figure Description
