Description

[Detailed description of the invention] Purpose of the invention This invention relates to a faucet handle that changes color in response to temperature changes inside the faucet. It is designed to allow you to tell at a glance whether hot water is flowing in or not.

Prior art The handle of a conventional faucet is made of transparent acrylic resin and has a blue or red indicator attached to it to enhance the aesthetic effect. There are many things that can be identified.

One example is the one described in Japanese Patent Laid-Open No. 50-9122.

The handle described in this publication is integrally molded by inserting a colored synthetic resin bushing into a transparent synthetic resin handle body, and the bushing does not discolor with changes in temperature.

However, a hot water faucet equipped with this type of handle has the disadvantage that it is difficult to tell whether hot water is actually flowing into the faucet.

For example, when a shower head is connected to a hot water faucet, when the next bather tries to use the shower by opening the hot water faucet immediately after the previous bather has used the shower,
It is not possible to tell from the outside whether there is hot water remaining in the shower head; hot water may suddenly come out when the hot water faucet is opened, or it may have been a long time since the previous bather used the shower. When the next bather tries to use the shower after the shower has passed, cold water often gets cold in the shower head and suddenly spits out cold water, causing discomfort.

Structure of the invention The present invention detects the temperature inside the faucet and changes color to make it easy to know whether hot water remains in the faucet.The following is a diagram explaining an example. In this case, the handle body 1 is made of transparent plastic, and a hollow space 2 is provided on the lower surface.

A thermal conductor 3 having a shape corresponding to the space 2 is formed of a metal with good thermal conductivity, and a temperature indicator that reversibly changes color according to temperature changes is applied to the surface of the thermal conductor 3 uniformly over the entire surface or at its temperature. The temperature indicator layer 4 is formed by coating so that letters or patterns indicating the temperature are exposed.

The temperature indicator may be applied in the form of a paint directly to the surface of the heat conductor 3, or a tape on which the temperature indicator layer 4 is formed may be attached.

The temperature indicator may be one with a two-step display that changes color when it reaches a certain temperature, but a temperature indicator that senses a certain temperature change and continuously changes color in multiple steps is more aesthetically pleasing and easier to detect temperature changes. Excellent at

Furthermore, temperature indicating agents having different color change temperatures can be applied in a striped pattern.

Note that an insertion hole 8 is provided at the axis of the bundle body 1 and an insertion hole 6 is provided at the axis of the thermal conductor 3.

A heat conductor 3 having a temperature indicator layer 4 on its surface is fitted into the space 2, and the end of the valve stem B protruding from the faucet body A is inserted into the heat conductor 3.
into the insertion hole 6 of the bundle body 1, and insert it from the top side of the bundle body 1 into the insertion hole 7L.
Screw the screw 7 inserted into the valve stem B into the valve stem B to connect the valve stem B and the heat conductor 3 so that the heat is conducted to the heat conductor 3 of the valve stem B.

An indicator 5 is mounted on the upper surface of the bundle body 1 to indicate whether it is a faucet or a hot water faucet.

Function of the invention In the hot water faucet equipped with the bundle of the present invention, when hot water is supplied to the hot water tap and the temperature of the heat conductor 3 gradually rises and reaches a certain temperature, the temperature indicator layer 4 It senses the temperature and changes color.

If the temperature indicator layer 4 is capable of changing into multiple colors, the color changes stepwise as the temperature rises.

Further, if the temperature indicator layer 4 is formed so that letters or patterns indicating the temperature are displayed, the actual temperature of the hot water in the hot water tap can be clearly seen at a glance.

The color change of the temperature indicator is reversible, so if the temperature of the water drops, it will immediately change to its original color.

It goes without saying that the present invention can also be applied to cocks and valves.

Effects of the invention This invention is a bundle made of transparent plastic containing a heat conductor with a temperature indicator layer that senses temperature changes and changes color, thereby increasing the aesthetic effect by changing color in response to temperature changes. .

In addition, the actual temperature inside the faucet is displayed as a color, so you can tell at a glance whether hot water or cold water is being discharged when you open the faucet. Eliminates discomfort caused by sudden discharge.
