Description

Automatic water splash shut-off device for sink

The disclosed content is formed in a sink and constitutes a water splash blocking device capable of adjusting the rotation angle of the upper frame to suit the user's body, preventing water from splashing to the user or the outside, and preventing the user's clothes from getting wet Water for sink It relates to an automatic frying blocker.

Unless otherwise indicated herein, material described in this section is not prior art to the claims in this application, and it is not admitted that the material described in this section is prior art.

In general, when washing in a sink, since the faucet is located higher than the top plate of the sink, there is a problem in that water hits the washing object or the cleaner's hand and splashes water around the sink, contaminating the surroundings, the floor, and the cleaner's clothes.

In order to prevent water from splashing out of the sink during the washing operation in the sink, the washing object must be positioned as low as possible toward the bottom of the washing tub, and to do so, the cleaner has to lower his posture as much as possible and bend his back a lot, which causes inconvenience.

Another method is to increase the overall height of the sink and deepen the bottom of the washing tub, but since each person has a different height, how to use the sink, and the environment around the sink are different, standardization of the structure is ineffective. .

In order to compensate for these disadvantages, conventionally, a water splash prevention plate detachable from the sink is formed and the height can be adjusted according to the user's height, thereby increasing the convenience of use and preventing tap water from splashing outside when washing dishes, Accordingly, an apparatus for preventing splash water in a sink preventing a user's clothes from getting wet has been disclosed.

As an example of such a sink splash prevention device, Republic of Korea Patent Registration No. 10-1186203 (published on October 8, 2012), in a state located inside the sink, extends vertically to the outside of the sink through a long hole formed in front of the top plate of the sink. It includes a blocking plate that is drawn out and a driving means that supports the blocking plate, drives it with power applied from the outside, and moves the blocking plate up and down. Disclosed is a sink splash blocking device that can prevent water from splashing and contaminating the surroundings or users and provides convenience in use by configuring the blocking plate to be automatically withdrawn.

In addition, Korean Patent Publication No. 10-2014-0021851 (published on February 21, 2014) discloses that a water splash prevention device having a cross section of 'Λ' shape is attached to the upper edge of the sink by an attachment means provided on the bottom surface of the sink to prevent water splashing. Disclosed is a water splash prevention and cleaning device for a sink that prevents water splash from a sink where water is frequently used and makes it possible to maintain the sink and surroundings in a clean and sanitary manner.

In addition, Korean Patent Registration No. 10-2295514 (published on August 31, 2021) includes a fixing plate installed on the sink top plate between the sink water tank and the user and a blocking plate protruding upward from the upper surface of the fixing plate, the blocking plate In the upper part, an arm insertion groove is formed that is recessed in the area where the user's arm is located, and is attached to a sink installed in a kitchen of each home or restaurant so that water from a faucet used when washing dishes or dishes splashes out Disclosed is a sink splash prevention plate that prevents scattering.
