Description

Anti-blocking vegetable washing sink for kitchen and using method

The invention relates to a divisional application of an anti-blocking vegetable washing sink for a kitchen, which is applied for 10, 18 and 2018 and has the application number of CN 201811214598.9.

Technical Field

The invention relates to the technical field of vegetable washing devices, in particular to an anti-blocking vegetable washing pool and method for a kitchen.

Background

At present, the living standard is continuously improved, a vegetable washing pool is arranged in a kitchen, and people can conveniently wash vegetables and dishes; a large amount of rice grains can be generated in the dish washing process, the density of the cooked rice grains is reduced, and the rice grains can flow along with water flow in water, so that the filter screen is easily blocked by the rice grains flowing along with the water when the water passes through the filter screen of the dish washing pool, people are required to continuously clean the filter screen in the dish washing process, and the use process is inconvenient.

During the process of the invention, a large amount of patent documents are searched in a patent network, such as patent numbers: CN107675762B discloses a kitchen is deodorant prevents stifled basin based on water seal, utilize the stifled structure of preventing of setting to avoid the delivery port to plug up, can understand in the drawing through the description, the stifled structure of this patent is only constituteed through the drainage pipe and an swash plate that the slant set up, but because the weight of the grain of rice is less, can drive the grain of rice and flow together when water is flowing, consequently, the grain of rice flow direction apopore can be taken to water, thereby the condition that the grain of rice stopped up the apopore can still appear, can not reach the effect of preventing stifled completely, and the grain of rice that stops up etc. also conveniently clear up.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides an anti-blocking vegetable washing sink for a kitchen, which solves the problem that the conventional vegetable washing sink is easy to block and is inconvenient to use.

bag 211 by using the air pressure, and the air in the air groove 210 flows upwards through the water outlet holes, bubbles are generated inside the vegetable sink body 1, and rice grains or vegetable leaves and the like on the water outlet hole of the filter funnel 201 are jacked upwards, so that the water outlet hole is not blocked; and when the distance between the bottom plate 205 and the top plate 209 is the shortest, the water level inside the hemispherical water receiving tank 215 just reaches the working water level of the automatic water dropping liner 216, the automatic water dropping liner 216 will discharge the water inside the hemispherical water receiving tank 215, then the hemispherical water receiving groove 215 moves upwards to the top by the weight of the sliding sleeve 203 and the bottom plate 205 on the sliding sleeve 203, the sliding sleeve 203 moves downwards to the bottom, then the hemispherical water receiving tank 215 will continue to collect water to generate weight, so that the sliding sleeve 203 will move upwards again, and repeat this operation until the water in the vegetable sink body 1 is completely discharged, and the rice grains or vegetable leaves on the water outlet hole of the filter funnel 201 will be pushed open by the characteristic of the bubbles which continuously float upwards, thereby guarantee can not have the grain of rice or the dish leaf to plug up filter funnel 201 to the in-process that washes the dish and wash the dish can not often clear up the filter screen, make people more convenient when using.

The working principle is as follows: when the water of the interior of the vegetable pool body 1 flows downwards, the air groove 210 and the air bag 211 can utilize the air bubbles to clean a group of the six groups of water outlets in batches, so that the filtering funnel 201 cannot be blocked on the premise of ensuring the normal drainage of the filtering funnel 201.
