Description

[Technical Field]



[0001] The present invention relates to an integrated height adjusting washstand device, and more particularly, to an integrated height adjusting washstand device capable of adjusting water supply and height adjustment within a range operated by a user to improve convenience in use, while increasing safety by improving a structure so that a means of adjusting a height of a washstand is integrated with a water supply device, and shutting off a height adjusting operation at the time of water supply in cooperation with water supply and height adjustment.

[Background Art]



[0002] In general, a washstand using tap water is installed for use in washrooms such as household toilets, public toilets, and various shower facilities, etc. The washstand that is fixedly installed with a predetermined height are universalized. Since such a height-fixed washstand is fixed to a wall at a limited height with respect to adults, there was a problem that it is inconvenient to use such a general adult height washstand for people who are taller or smaller than the installation height thereof, especially for children.

[0003] Accordingly, various types of technologies for adjusting the height of the washstand are developed and used.

[0004] As a conventional washstand height adjusting device, a device that installs an electric motor to the washstand to move up and down by a user's operation was used.

[0005] However, since the washstand is installed inside a bathroom and moisture remains in the surroundings, and a risk of electric shock is increased when using electric power, there was a problem that a cost is increased to improve waterproof performance.

[0006] Accordingly, in recent years, a height adjusting device has been developed and used in which a height is adjusted by an operation of a user in a cylinder method using a pressure of cold water supplied to a water faucet.

[0007] However, since a conventional height adjusting device should be installed separately on one side of the water faucet of the washstand, an installation space is required for separate installation on the washstand, and it is difficult to install with the existing washstand, so that a dedicated washstand should be manufactured and constructed separately, and accordingly, there was a problem that a cost is increased.

[0008] In addition, since the conventional height adjusting device shares the cold water with the water faucet, when the height is adjusted while using cold water in the water faucet, an amount of cold water used is reduced, and when cold water usage is stopped in a state in which the height adjustment is not operated immediately, the height adjustment is operated suddenly, and there is a problem that a risk of injury is increased due to a movement of the washstand which a user may not expect.

[0059] Such an operation shut-off part 140 includes a shut-off body 141, a shut-off valve part 144, and a valve elastic part 146.

[0060] The shut-off body 141 is disposed inside the operation body 131, and is installed in the supply pipe 133, and has a shut-off space 142 therein that is a space through which the cold water supplied to the operation body 131 passes, and is formed with a shut-off inclined portion 143 inclined such that a cross-sectional area of a flow path is reduced to a connection side of the cold water supply pipe 113 in the shut-off space 142.

[0061] The shut-off valve part 144 is disposed inside the shut-off body 141, and is provided so as to open and close the flow path through which the cold water of the water faucet body 111 passes while moving inside the shut-off space 142, and is formed with a valve inclined portion 145 so as to have an inclination in contact with the shut-off inclined portion 143 in a direction of the cold water supply pipe.

[0062] The shut-off inclined portion 143 and the valve inclined portion 145 are provided with an inclination in which an area contacted when the shut-off body 141 is closed by the shut-off valve part 144 is enlarged, and the closing efficiency may be further improved.

[0064] That is, the cold water is used as the water supply through the cold water supply pipe 113 and the water supply part 118 by operating the water supply control lever 114, and is used together in height adjustment while being supplied to the adjusting cylinder 121 through the supply pipe 133 by an operation of the operation lever 132.

[0065] Therefore, when cold water is supplied during height adjustment, smooth water supply is difficult, and an amount of cold water required for height adjustment is reduced, so that the height is not adjusted to the height desired by the user. When cold water is used, even when the height is adjusted, the height is not adjusted immediately due to a malfunction by the user, but the height is suddenly adjusted, and the washstand is moved in a state not expected by the user, and thus there was a problem that the user is injured.

[0066] Accordingly, the shut-off body 141 is installed at a position supplied to the supply pipe 133 through the cold water supply pipe 113 so that the shut-off valve part 144 shuts off the shut-off space 142 by an elastic force of the valve elastic part 146 when the user uses cold water, and the cold water is prevented from being supplied to the height adjusting operation part 130 and the height adjustment is suppressed, and thus it is possible to prevent a deterioration of safety due to a malfunction.
