Abstract

PURPOSE:To unnecessitate a conventional pump and tank and make compact a mouth-washing device or the like to facilitate the assembling by equipping a proper heatexchanger in a multi-purpose water feeder having a small flow rate like a mouth washing device or the like in a washstand and designing to be a directly connected type for tap water. CONSTITUTION:A multi-purpose water feeder 30 for a small flow rate to be useful for washing mouth, washing hair, etc., is equipped on a washstand. On the other hand, a hot water feedpipe 19 and a water feed pipe 20 are jointed to a faucet 7, and a branch pipe 21 is connected to the water feed pipe 20. The branch pipe 21 is connected to the conductive pipe 40 of the multi-purpose water feeder 30 trough a flow rate adjusting value 39. That is conduct pipe 40 is connected to a proper heatexchanger 41 and composed of a heatxchanger 42 and a heater 43. When washing mouth is washed by the use of a proper nozzle 54 for instance, the dial 35 is turned to put on the electric source switch 37 and to open the flow rate adjusting valve 39, and another dial 36 is turned to adjust the supplying electric power to the heater 43.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washbasin equipped with a small-flow multi-purpose water discharging device used in an oral cleaning device or the like.

0002

2. Description of the Related Art A washstand equipped with an oral cleaning device is disclosed in Japanese Utility Model Publication No. 60-6304. This technology is
A pump for pressurizing wash water is provided inside the main body of the vanity, and the wash water uses tap water or warm water obtained by mixing hot water and water generated by a water heater.

[0003] Furthermore, the technique disclosed in Japanese Patent Application Laid-Open No. 64-83255 is equipped with a water faucet for supplying tap water or mixed water of hot water and a water spouting device for oral cleaning to a wash basin or hand washing stand.

0004

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, Utility Model Publication No. 60-6304 has a structure in which pressurized water for washing is obtained by a pump, so a pump and an accompanying tank are required, and the problem is that Since these items are housed within the main unit, they occupy a large space within the main unit, causing interference with other equipment and hindering the freedom of equipment layout.
This is disadvantageous in terms of space, and as a result, the external size of the washstand and the like becomes larger.

[0005] In addition, both of the above-mentioned techniques use a mixture of hot and cold water for a faucet to obtain a small flow of hot water for oral cleaning. By the way, hot water for supplying faucets is generated by a water heater.
If you try to obtain hot water at a small flow rate, such as for oral cleaning, there is a problem that the water heater will not ignite when starting up because the flow rate is small. In order to avoid this and make it usable, it is necessary to supply a large amount of tap water, which results in a large amount of waste water, and it takes a long time to heat the water.
It is unfavorable in terms of resource and energy conservation.

In addition, the piping from the water heater to the faucet and the small-flow water outlet is long, and hot water is not readily available, making it difficult to use it quickly when needed, and resulting in poor functionality and ease of use.

[0007] The present invention has been made to solve these problems, and its purpose is that the attached small flow water discharging device has excellent instant hot water performance, extremely excellent functionality and ease of use, and improves grooming as a whole. To provide a washstand which is excellent in terms of resource and energy saving and which does not generate wasted water when discharging water at a small flow rate.

[0008]

[Means for Solving the Problems] The means for solving the above problems is to provide a sink bowl, a faucet for supplying tap water, mixed hot water, etc., and a small flow rate system for supplying hot water at a small flow rate. The multipurpose water discharging device is a washbasin that is configured to be directly connected to the water supply and equipped with a dedicated heat exchanger on the downstream side of the tap water inlet. Further, the multipurpose water spouting device is a washstand that is detachably equipped with various nozzles that spout a small flow of warm water for purposes such as mouthwashing and hair styling.

[0009]

[Operation] According to the above means, the small flow multi-purpose water discharging device installed in the washbasin is equipped with a dedicated heat exchanger, and therefore, even when discharging hot water at a small flow rate during oral cleaning, hair styling, etc. You can get the hot water you need quickly with a dedicated heat exchanger without relying on a water heater, and you can quickly get hot water at tap pressure when you need it without having to waste water. Since it only includes a dedicated heat exchanger, it is compact, and it is advantageous in terms of space when incorporated into a washbasin, and does not hinder the degree of freedom in design.
