Abstract

<P>PROBLEM TO BE SOLVED: To prevent a boiling water accident or the like caused by sudden raising of a lever, by quickly and positively moving the operating lever into a position of the medium temperature and medium discharge amount of hot water, and allowing a discharge stop position to always come to the low temperature discharge side in a hot water temperature control device for a single lever combination faucet. <P>SOLUTION: A stopper device with a spherical tip part including a spring is mounted to the spherical upper part of a faucet body housed by the semicircular shape of an operating lever bottom part. The semicircular inner peripheral surface of the operating lever bottom part is provided with a projecting line with an arc upward on the hot water side from a lower part. A shorter line projected at a right angle to the line is provided in front of a high temperature region of the line. The movement of the lever is regulated and released by the projecting lines and the stopper to easily move the lever into the medium temperature discharge position in a safe region. When moving the lever into a high temperature discharge position, the stopper is pressed hard to the shorter line. The lever can thereby be moved into the high temperature region over the line to allow discharge. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

Detailed Description of the Invention

The present invention relates to a hot water temperature control device for a built-in single lever mixing faucet.

It seems that a device that prevents the discharge of hot water has been devised, but then the goodness of the original single lever mixing faucet is lost. Since the movement of the operating lever was developed so that it can rotate freely, there is no technology to restrict and release the movement of the lever, and a device that takes into account the safety aspect that the water discharge stop position is always in the low temperature range Nor.

Problems to be solved by the invention

Single lever mixed faucets are widely used as faucets for kitchens and bathroom vanities because they can quickly switch between water and hot water and adjust the discharge volume. In order to move the lever, it is necessary to rely on experience and feeling, and it is necessary to fine-tune the operating lever several times.
Also, if the lever is lowered at any position, such as high temperature, medium temperature, and low temperature, the water will stop, but after discharging at high temperature, the operation lever will be lowered and water will stop, and the hand will immediately be washed up. It seems that there are many accidents that cause burns with hot water discharged from the lever at a high temperature.
The built-in single lever mixing faucet temperature control device of the present invention can move the operation lever quickly and reliably to the hot water medium temperature and medium discharge amount position, and the discharge stop position is always on the low temperature water discharge side. The purpose is to prevent accidents caused by hot water by unexpectedly raising the lever when it comes.
In addition, it is possible to stop the water by lowering the lever directly from any hot water temperature range, which was not possible with the hot water temperature control guide for an external single lever mixed faucet that was pending application for a utility model. The purpose is to provide a built-in single-lever water faucet controller.

Means for solving the problem

In order to solve the above-mentioned problems, the present invention attaches a spherical stopper device with a built-in spring to the spherical upper part of the faucet body, which includes the semicircular shape of the bottom of the lever of the single lever mixing faucet. In addition, on the inner surface of the semicircular shape at the bottom of the control lever, a protruding line with an arc upward from the bottom to the hot water side is provided. The contact part between the upper part of the line and the stopper should be the discharge stop position in the low temperature part. A short line projecting at a right angle to the line is provided in front of the high temperature range of this line. This position becomes the position of medium temperature and medium discharge amount, and the tip of the stopper device comes into contact with the line, so that the normal movement of the operating lever cannot pass the line. A built-in single-lever mixed faucet water temperature control device that allows the lever to move to a medium temperature discharge position in a safe area without restricting the movement of the lever by protruding lines and stoppers is supplied.

At the same time, when moving the lever to the high temperature discharge position, the built-in single has the feature that the lever can be moved to the high temperature range across the line by pressing the stopper strongly against the short line mentioned above. Supply a hot water temperature control device for lever mixing faucets.

In addition, deliberately pushing the operating lever down to the line makes it possible to stop the water down from any hot water temperature range, and to stop water normally. This is a built-in single lever mixing faucet temperature control device that also has the feature of stopping the discharge.

An embodiment of the present invention will be described. As shown in FIG. 1, a spherical stopper device 003 with a built-in spring is attached to the spherical upper part 102 of the faucet body, which is contained in the semicircular 101 at the bottom of the operation lever of the single lever mixing faucet. Furthermore, a projecting line 001 is provided on the semicircular inner peripheral surface at the bottom of the operating lever, with a protruding arc from the bottom to the hot water side. The contact area between the upper part of this line and the stopper is the discharge stop position in the low temperature part. A short line 002 projecting at a right angle to the line is provided in front of the high temperature range of this line. As shown in FIG. 3, this position is a medium temperature, medium discharge amount 04, and the tip of the stopper device. 004 in FIG. 5 is in a state where the line cannot be passed by a normal operation lever movement by contacting the line. become. By regulating the movement of the lever with the protruding line and stopper, the lever can be moved to the middle temperature discharge position 04 in the safe area without being easily confused.

When the lever is moved to the high temperature discharge position in FIG. 4, the stopper tip 004 is strongly pressed against the short line 002 as described above to become 002 and 004 in FIG. It becomes a built-in single lever mixing faucet hot water temperature control device with the feature that the lever can be moved and discharged.

By deliberately pushing down the operating lever to the line, it is possible to cross the line even in relation to the protrusion line 001, so that the water can be stopped by lowering the lever directly below any hot water temperature range. In addition, it is a built-in single lever mixing faucet temperature control device that always has the feature that the discharge always stops in the low temperature range because the lever moves along the line 001.

The invention's effect

As can be seen from the above description, the hot water temperature control device for the built-in single lever mixing faucet of the present invention has two lever lines and a spring built-in stopper without blocking the advantages of the conventional single lever. It is easy and unconfusing to move the movement of the lever, and it is possible to move the lever to the middle temperature discharge amount and high temperature large discharge amount positions, and the discharge stop position must be on the low temperature water discharge side. It is also possible to prevent accidents caused by hot water by unexpectedly raising the lever by the operation lever coming.

It is a cross-sectional view showing the stopper and protrusion line of the upper spherical part of the faucet body, which is contained in the semicircle at the bottom of the control lever. It is a front view showing the discharge stop position of the hot water temperature control device for a built-in single lever mixing faucet of the present invention. It is a front view showing the position of the discharge amount in the middle temperature. It is a front view showing the position of high temperature and large discharge amount. It is a sectional view showing the restricted state of the stopper and the line. It is a sectional view showing the state of release of the stopper and line.
