PURPOSE:To display water temperature with colored light by employing a temperature sensor for moving a multi-colored filter by sensing water temperature, a light source disposed on one side of the colored filter, and light guiding means with its one end disposed on the opposite side of the light source and with the other end thereof disposed in the water outflow direction of a fauset. CONSTITUTION:When a light source 20 is energized and hot water is sent forth from a fauset 120 by operating a hot and cold water mixing valve 100, the hot water temperature in the fauset 120 is detected with a main body 31 of a temperature sensor 30 exposed in a flow passage 124, multi-colored filter 10 is rotated or moved according to the valve of the temperature, and light of the color corresponding to the filter color is irradiated from the end of light guiding means 40 to the water being discharged. As result, hot water being discharged out of the end of the fauset 120 or tableware being hit with the water emits light of the color corresponding to the water temperature. A user therefore can easily know whether the hot water can be touched or not according to the colored light of the water discharged out of the fauset 120.

Description

[Detailed Description of the Invention] (Field of Application in Industry 1) The present invention relates to a hot water mixing faucet that mixes and discharges hot water and water.
In particular, the present invention relates to a hot water mixing faucet and a faucet thereof, in which the temperature of hot water being discharged can be determined by colored light of the hot water.

(Prior art) A hot water mixing faucet mixes an appropriate amount of S and water to discharge hot water at a temperature suitable for use. Temperature 1■ cannot be detected by the user unless he or she touches it directly with his or her hands.

5 For example, in JP-A No. 60-105722, it is stated that ``an ice temperature indicating device such as a thermometer or a temperature measuring base is attached to the water faucet or the tip of the faucet.
Is there a proposal for a faucet with a temperature indicator?
It is true that if you use this water temperature indicator k, you can know the temperature of hot water, albeit indirectly. However, because
Judging from the content described in the above publication, the above-mentioned ice indicator does not directly measure the temperature of hot water, but indirectly measures the temperature of hot water by knowing the temperature outside the faucet. It is something to know about 1 yen L. Therefore, immediately after opening the faucet, even though hot water is being discharged,
It is possible for the water temperature display device to indicate a low temperature, which may cause burns to the user. The above is applicable to the "temperature detection device for water supply" proposed in Japanese Utility Model Publication No. 57-110176, or the "temperature display mixing faucet" proposed in Japanese Utility Model Publication No. 62-185765. The same is true.

On the other hand, the "water faucet with thermometer" shown in Utility Model Publication No. 56-150276, or the actual 1v (60-
No. 169369! 41 Niir<Sale f: 188R Fixed Boiler" is a type in which the tip of the thermometer is brought into contact with the hot water in the faucet by 1μ, so are there any problems as mentioned above?6. What can be said about all of the inventions shown in these publications is that the ``temperature display tool'' and ``thermometer'' are small, so users cannot use them. This is because of the inconvenience of not being able to know the temperature of the water unless you keep an eye on it.

Based on the above, 9. As a result of extensive research into how to accurately determine the temperature of hot water discharged from a mixing faucet into the cylinder,
They have newly discovered that adding colored light to the hot water discharged from a hot water mixer faucet can bring about good results. Therefore, when I investigated the conventional technology, I discovered that
I discovered that a "light-emitting faucet" was proposed in Publication No. 7-25951. This "luminous faucet" is.

According to the claims of the above-mentioned publication, ``Several color filters of different colors are combined in one circular frame or in a band shape and arranged in a rotary formation, and the color filters are used as a light source. It is a light-emitting type water faucet that is placed in the middle of a waterway leading to the light source and is interposed in the middle of a waterway leading to the light source, and is designed to give color to the water column suspended from the faucet. According to the description in Publication E, "faucet color is changed sequentially to match each filter color, 11! A dynamic and dynamic case can be developed, with the effects of objects and the environment in the exhibition hall.

"It can be extremely effective in advertising."

However, the "light-emitting faucet" disclosed in Japanese Patent Application Laid-Open No. 47-25951 does not change the color of the light in the water column depending on the temperature of the hot water, and the light that passes through the filter "opens and closes". Since it has to pass through the hole 154 of the valve 16J, the opening/closing valve 16J having the hole 151 is an essential condition and cannot be applied to a general hot water mixer faucet.

(Problem to be solved by the invention) The present invention has been made based on the above circumstances.
The problem to be solved is to provide hot water with light of a color corresponding to its temperature.

An object of the present invention is to provide a hot water mixer faucet which can display the temperature of hot water coming out of the snake using colored light, and which allows the user to use it with peace of mind. There is a particular thing.

(Means for Solving the Problems) In order to solve the above problems, the child actors employed in the invention according to the first claim will be described with reference numerals used in the examples.

(Function and Use of the Invention 11) Next, the function of each invention configured as described in (E) will be explained together with the modes of its use.

Regarding the hot and cold water mixer faucet (100) according to the first claim, first, in this hot water and cold water mixer faucet (1110), before use, the light source (20) is turned on for 1'lt. This allows the light from the light source (20) to reach the tip of the faucet (120) through the light guiding means (40) to the object located at the tip of the faucet (120), or the light to reach the user if left as it is. is not clearly visible.

Therefore, when the user operates the hot water mixing faucet (+00) to discharge hot water from the faucet (1211), the temperature of the hot water in the faucet (1211) is detected by the temperature sensor exposed in the flow path (124). (30) It is sensed by the Φ body (31). Depending on the temperature of this hot water, a color filter (
Ill) is rotated or moved, and light of a corresponding color is irradiated from the tip of the light guide means (40) into the hot water currently being discharged. As a result, the hot water discharged from the tip of the faucet (+20), or the shade that it hits, emits light of a color corresponding to its temperature.

Of course, if the user changes the temperature setting on the hot water mixing faucet (100) while hot water is being discharged, the temperature of the hot water in the flow path (124) will change accordingly, and this will be detected. A color filter (lO
) or rotated or moved. Accordingly, the faucet (12
The colored light of the hot water discharged from the tip of G) changes.

Therefore, the user B can easily judge whether or not it is okay to directly touch the hot water depending on the change in the colored light of the hot water discharged from the tip of the faucet (120).
It is effective immediately after use, when the temperature of hot water according to Section 2 of Temperature 0) often does not match the setting. Also, the faucet (
120) The hot water discharged from the tip of the hot water or the food 3 etc. that this hot water hits shines with colored light, so it is difficult to judge the temperature of the hot water being discharged. This makes it easy to use even when the user is far from the hot water mixer faucet (100) or when the user is nearsighted.

This is done by a fluid pressure switch (21) placed in the flow path (<124) of the 4-faucet (+20), and when hot water starts to flow in the flow path (124), the fluid pressure switch (21) is activated. ) is pressed, which energizes the light It (20) and lights it up.

- Regarding the faucet (120) according to the third claim, of course, this faucet (120) can be connected to the outlet (111) provided in the faucet body of the hot water/cold water mixing faucet (100). ), the mixed hot water is discharged at a predetermined position.However, in the faucet (120) according to the third claim, the temperature of the hot water to be discharged is controlled. All of the components for providing colored light corresponding to the color are incorporated.

Therefore, this faucet (1211) not only gives colored light to hot water according to its temperature, but also is completely independent from the configuration of the S wood mixer faucet (100), so it is difficult to mix hot water and water. It is hardly affected by the configuration of the faucet (100) and can be applied to any type of hot water mixing faucet (100).

(Example) Next, the invention according to each claim will be described according to an example shown in one drawing. Here, a detailed explanation of the invention according to the first to third claims will be made.
