Description

Aspects of the present invention generally relate to washbasins with vertical walls.

In a washbasin such as a vanity where water used for hand washing or fetching water is received by a bowl provided on the counter, a structure in which a faucet device is attached to a standing wall provided close to the bowl is widely adopted.

A washbasin with a standing wall is generally installed so that its back surface abuts on the building wall. Therefore, when a washbasin having a bowl and a standing wall standing behind it is arranged so that its back surface abuts on the building wall, a water supply pipe is formed between the standing wall of the washbasin and the building wall. It will be arranged in the gap.

By the way, if the distance between the building wall and the standing wall is shortened, the bathroom vanity can be made to look neat. For that purpose, it is preferable to make the gap small. However, if the gap is made too small, it becomes difficult to route the water supply pipe in the small gap after the back surface of the bathroom vanity is installed so as to be in contact with the building wall.

However, according to the law, only those who have a predetermined qualification (qualified person for waterworks) can arrange the water supply pipes so that water can be supplied from the water pipes. In some cases, the commercial distribution of the vanity does not go through a qualified person for waterworks, so an installer who installs the vanity (unqualified person for waterworks) and an installer who arranges water supply pipes (qualified for waterworks). Person) is often different. In such a case, the installer first brings the bathroom vanity to the site, and once the bathroom vanity is brought into contact with the building wall and then fixed. At a different timing from the fixing work, the disposer removes the screws that fix the bathroom to the building wall, pulls the bathroom away from the building wall, and then arranges the water supply pipes. , The bathroom vanity must be re-fixed against the building wall.

In order to avoid the above-mentioned complicated work, the bathroom vanity that was previously installed by the installer in contact with the building wall is not moved to the through hole formed in the vertical wall from the front side. By inserting a water supply pipe, a method is conceivable in which the water supply pipe is arranged in the gap between the vertical wall and the building wall, the water supply pipe is passed under the counter, and is connected to the pipe extending from the building wall under the counter. However, in such a method, when the distance between the building wall and the standing wall is short, there is a possibility that the inserted water supply pipe interferes with the building wall and scrapes the building wall.

For example, in Japanese Patent Application Laid-Open No. 2015-54163 (hereinafter, Patent Document 1), there is known a configuration in which a rigid pipe cover member is provided on the back surface of a standing wall of a washbasin for the above problem.

On the other hand, in recent years, not only a water discharge member for discharging water toward a bowl but also a member (electric member) requiring electric power such as an automatic faucet and a lighting device is to be attached to the front side of the standing wall of the washbasin. There is movement. At that time, if the electrical wiring is passed through the inside of the piping cover member, the electrical wiring and the water supply piping may be entangled, and there is a risk of electric leakage of the electrical wiring. ..

JP-A-2015-54163

However, when installing the electric member on the front surface of the standing wall of the wash basin, the disposer installs electrical wiring from the front surface of the wash basin between the back surface of the piping cover member provided on the back surface of the standing wall and the building wall. Pass through. At that time, if an attempt is made to adjust the position of the electrical wiring in the left-right direction starting from the piping cover member, the gap between the back surface of the piping cover member and the building wall is small, which makes it difficult to route the electrical wiring. be.
