Abstract

PROBLEM TO BE SOLVED: To visually recognize the temperature of a liquid by a means excepting the place of a lever by mounting a temperature information means informing the outside of the temperature of the liquid discharged from a discharge opening. SOLUTION: A second sheet layer 22 is held between a transparent pressure- sensitive adhesive sheet layer 20 and a first sheet layer 21, and a thermo-label 19 is formed. The thermo-label 19 is stuck on the top face of a delivery pipe 16 supported to the body of a mixing-faucet cock through the transparent pressure-sensitive adhesive sheet layer 20. When an outside temperature is less than 40 deg.C when the cock is not used, the color of the thermo-label 19 is changed into the blue of the second sheet layer 22. When a user operates a lever installed to the body of the cock, water is discharged from a discharge opening. When the user erroneously operates the lever and hot water at 40 deg.C or higher is discharged from the discharge opening, the delivery pipe 16 is heated, the color of the second sheet layer 22 is changed into a transparent color by the heat of the delivery pipe 16, and the red color of the first sheet layer 21 can be confirmed.

2. Description of the Related Art In recent years, as a faucet used in a kitchen or the like, a mixed faucet faucet capable of selectively discharging hot water or water from one faucet has become mainstream. This faucet is provided with two pipes, a hot water supply pipe connected to a water heater such as a boiler and a water supply pipe connected to a water pipe. And
Hot water supplied from the hot water supply pipe or water supplied from the water supply pipe is discharged from the discharge port based on a lever operation provided on the body.

[0003]

However, the above-mentioned conventional faucet has the following problems. The user may mistakenly operate the lever to eject cold water (hot water) even though the user has attempted to eject hot water. When the user does not notice this and touches the ejected liquid, the difference between the temperature of the liquid predicted by the user and the temperature of the actually ejected liquid is large. The user was sometimes surprised.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a faucet in which the temperature of discharged liquid can be visually recognized by means other than the lever position.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 is provided with a temperature notifying means for notifying the temperature of the liquid discharged from the discharge port to the outside. And

[0006] The gist of the invention according to claim 2 is that the temperature notifying means switches to two colors and changes color at a predetermined temperature as a boundary. The gist of the invention according to claim 3 is that the temperature notification means changes color to blue below a predetermined temperature and to red above a predetermined temperature.

In a fourth aspect of the invention, the gist of the temperature notification means is that it is composed of an ink layer whose color changes with temperature. According to a fifth aspect of the invention, the gist of the invention is that the ink layer is mounted so as to be covered with a transparent adhesive sheet.

Therefore, according to the first aspect of the invention, since the temperature of the liquid discharged from the discharge port is notified to the outside by the temperature notification means, the user does not touch the discharged liquid. You can check the temperature.

Therefore, in the invention described in claim 2, in addition to the operation of the invention described in claim 1, since the temperature notification means switches to two colors at a predetermined temperature as a boundary, the temperature of the liquid to be ejected is changed. Is easy to judge.

Therefore, in the invention described in claim 3, in addition to the function of the invention described in claim 1 or 2,
The ink turns blue below a predetermined temperature (when the liquid temperature is low) and red above the predetermined temperature (when the liquid temperature is high). That is, since red is generally used as the color for producing the image of hot water and blue is used as the color for producing the image of water, the user can quickly determine the temperature of the liquid to be ejected based on the color of the ink. it can.

Therefore, in the invention described in claim 4, in addition to the effect of the invention described in any one of claims 1 to 3, the temperature of the liquid can be confirmed by the color condition of the ink layer. Therefore, in the invention described in claim 5, in addition to the effect of the invention described in claim 4, since the ink layer is mounted so as to be covered with the transparent adhesive sheet, the workability in assembling is improved.

A lever 18 is provided on the upper portion of the body 13, and a valve body for opening and closing the communication port is connected to the lever 18. The lever 18 can be turned up and down and left and right with respect to the body 13. When the lever 18 is lowered and turned to the left, the hot water supply pipe 14 and the discharge pipe 16 communicate with each other. Hot water (hot water) is discharged from the discharge port 17. Further, when the lever 18 is lowered downward and rotated rightward, the water supply pipe 15 and the discharge pipe 16 communicate with each other, and water is discharged from the discharge port 17. By adjusting the position of the lever 18, a mixture of hot water and water can be discharged from the discharge port 17. When the lever 18 is raised, the communication port is closed and the discharge of hot water and water from the discharge port 17 is stopped.

As shown in FIGS. 1 and 2, the discharge pipe 1
On the upper surface of 6, a thermo label 19 is attached as a temperature notification means. As shown in FIG. 2, the thermolabel 19
Is a transparent adhesive sheet layer 20 having adhesiveness on the back side, a first sheet layer 21 in contact with the discharge pipe 16, and a first sheet layer 21 sandwiched between the first sheet layer 21 and the transparent adhesive sheet layer 20. It is composed of three layers of two sheet layers 22. The first sheet layer 21 is made of red synthetic resin. The second sheet layer 22 is made of a special ink that changes color according to the external temperature.

In the present embodiment, the second sheet layer 2
As the inks that compose No. 2, "Thermo Reversal 40C Blue Powder" and "Vinyl SA-5 Medium" manufactured by Tanaka Chemical Co., Ltd., and "Vinyl SA-5"
It is formed from a mixture of three types of "solvents". And as for the mixing ratio, "thermo reversal 40 ° C

5-Medium "60-70%, and" Vinyl S
"A-5 solvent" is 10 to 20% with respect to the mixture of "thermo reversal 40 ° C blue powder" and "vinyl SA-5 medium".

The characteristic of the "thermo-reversal 40 ° C blue powder" is a powder which is maintained in a blue state at a temperature of less than 40 ° C and changes transparently at a temperature of 40 ° C or more. Also, "Vinyl SA-5 Medium" is a transparent solvent and does not discolor with temperature.
"Vinyl SA-5 solvent" corresponds to a diluting solution for facilitating the mixing of "Thermo Reversal 40 ° C Blue Powder" and "Vinyl SA-5 Medium", and these were mixed and cured. The material becomes the second sheet layer 22. The transparent adhesive sheet layer 20 and the first sheet layer 21 are made of synthetic resin that always retains the same color.

The first sheet layer 21 and the second sheet layer 22 have the same diameter, and the transparent adhesive sheet layer 20 has a larger diameter than the first and second sheet layers 21 and 22. The transparent adhesive sheet layer 20 allows the first and second sheet layers 21 and 22 to be formed.
Are fixed to the discharge pipe 16.

Next, the operation of the present embodiment will be described. First, when the faucet 12 is not in use, the external temperature is 40%.
When the temperature is lower than 0 ° C., the color of the thermolabel 19 exposed to the outside is the blue color of the second sheet layer 22 (see FIG. 3A). In this state, when the user uses water, the lever 18 is rotated rightward and lowered to the front. Then, as described above, water is discharged from the discharge port 17.

Here, it is assumed that the user mistakenly rotates the lever 18 to the left to discharge hot water of 40 ° C. or higher from the discharge port 17. At this time, the heat of the hot water conducts through the discharge pipe 16, so that the heat also heats the entire discharge pipe 16.
The heat of the discharge pipe 16 causes the color of the thermo label 19 to change color (see FIG. 3B). That is, the external temperature is 40 ° C
If less than, the second sheet layer 22 that was blue turns transparent. Therefore, the color red of the first sheet layer 21 can be confirmed from the outside. The user can confirm that the color of the thermo label 19 is red and that the hot water discharged from the discharge port 17 is 40 ° C. or higher. As a result, the user does not touch the hot water even if the hot water is accidentally discharged despite the attempt to discharge the water, and it is visually confirmed that the liquid discharged from the discharge port 17 is the hot water. You can check.

In the present embodiment, the following effects can be obtained by configuring the mixed faucet faucet 12 as described above. (1) By attaching the thermo label 19 to the outside of the discharge pipe 16 for notifying the temperature of the liquid discharged from the discharge port 17, the user can check the temperature of the liquid without touching the discharged liquid. . As a result, it is possible to eliminate the risk of accidentally touching hot water.

(2) Since the temperature of the liquid can be easily confirmed without using a large-scale device such as a thermometer, it can be carried out at a low cost. (3) The discharge port 17 is changed depending on the color change of the thermo label 19.
Since the temperature of the liquid ejected from the can be confirmed, unlike a thermometer that reads a scale, the visibility is good and the user can quickly confirm the temperature of the liquid.

(4) Since the thermolabel 19 switches between two colors of blue and red at 40 ° C. as a boundary, the color changes,
The user can determine at a glance whether the liquid to be ejected is water or hot water. The discoloration boundary temperature of 40 ° C. of the second sheet layer 22 set in the present embodiment is a temperature at which humans feel uncomfortably hot when touching the skin. Therefore, in the present embodiment, the color change boundary temperature of the thermolabel is set to 40 ° C.

(5) The thermolabel 19 is made to change its color to blue below 40 ° C. and to red above 40 ° C. The reason why the color of the thermo label 19 is set to blue and red is that in the faucet relation, blue is generally “water” and red is “hot water”. Two colors are set. In this way, by setting the color of the thermo label 19 to blue and red, a user who uses the thermo label for the first time can easily determine whether the liquid ejected from the ejection port 17 is water or hot water.

(6) Since the thermolabel 19 is attached so as to be covered with the transparent adhesive sheet, the sticking work to the discharge pipe 16 can be easily performed and the thermolabel 19 from the discharge building 16 can be easily attached. Ink peeling can be prevented.

The present invention may be implemented as follows. (1) In the above embodiment, the ink that changes color at the external temperature is used as the temperature notification means, but a thermometer using alcohol is attached to the discharge pipe 16 or a thermistor is attached to the discharge pipe 16. However, the temperature detected by the thermistor may be embodied as a temperature notifying unit that is displayed on the display panel.

(2) In the above embodiment, the discoloration boundary temperature of the thermo label 19 as the temperature notification means is set to 40 ° C.
However, this temperature may be appropriately changed and embodied. (3) In the above-described embodiment, the thermo label 19 as the temperature notification means is attached to the upper surface of the discharge pipe 16, but the attachment position of the thermo label 19 may be appropriately changed to embody the present invention.

(4) In the above embodiment, the thermo label 19 as the temperature notifying means is constructed so as to change its color into two colors, blue and red, but it is embodied so that the thermo label 19 is changed in other colors. Good.

(5) In the above embodiment, the thermo label 19 as the temperature informing means is arranged to inform the temperature of the liquid by changing the color to two colors. May be embodied so as to be notified. For example, below the specified temperature
Further, the character "hot water" is made to rise above a predetermined temperature.

(6) In the above embodiment, the thermo label 19 serving as the temperature indicating means is adhered to the discharge pipe 16 and is embodied. However, the discolored ink constituting the thermo label 19 is directly printed on the faucet 12 of the mixing faucet. You may embody it.

(7) In the above embodiment, the second sheet layer 22 constituting the thermolabel 19 as the temperature notification means.
Is an ink that changes its color to blue at a temperature lower than a predetermined temperature (40 ° C.) and becomes transparent at a temperature higher than the predetermined temperature, and the red color of the lower first sheet layer 21 is exposed to the outside when transparent.

On the other hand, when the temperature is lower than a predetermined temperature, the powder is blue, and when the temperature is higher than the predetermined temperature, a powder that changes color transparently and a red powder that cannot change color are mixed and dissolved in a solvent to form an ink. To do. In this case, the mixed ink is a reddish blue color at a predetermined temperature and changes to a red color at a predetermined temperature or higher. With such a configuration, the number of laminated sheet layers forming the thermolabel 19 can be reduced, and the cost can be further reduced.
