Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a systematic system that can supply not only hot water of a set appropriate temperature while maintaining the set temperature by an automatic temperature control function, but also hot water and cold water. Regarding the mixing stopper.

[0002]

2. Description of the Related Art Conventionally, there is a thermostat mixing valve as a mixing stopper capable of supplying hot water, hot water, and cold water having a set appropriate temperature and automatically maintaining the set temperature. However, the conventional thermostat mixing valve has only one The temperature from cold water to hot water is set and adjusted by an adjusting valve, and an opening / closing valve provided downstream of this adjusting valve is opened to discharge water, hot water, or hot water adjusted by the adjusting valve.

[0003]

The above-mentioned conventional thermostat mixing valve has the following problems.

Since the structure is such that one adjustment valve discharges cold water to hot water, there is a risk that hot water may be discharged by an erroneous operation, which is dangerous. There is also provided a safety button on the temperature control handle that prevents you from setting a high temperature above a certain temperature without operating this safety button, but if the temperature setting is hot water, do you notice it? If you open the open / close handle carelessly, hot water will be discharged. Therefore, for safety, it is necessary to always check the set temperature before opening the on-off valve, which is very troublesome, and it is a place where consideration is desired for the elderly who tend to be distracted.

Since the temperature is controlled by one valve, a response delay occurs until the temperature moves from cold water or hot water to an appropriate temperature, and it takes time for the temperature to stabilize. In addition, this response delay causes the temperature to overshoot, which is dangerous.

In use, since it is necessary to operate the on-off valve after adjusting the temperature with the temperature control valve, the operation is troublesome and time-consuming.

Since it is necessary to discharge water from cold water to hot water with one temperature control valve, not only the operation is complicated, but also the frequency of use is high and it is difficult to improve reliability.

In actual use, it is rare that a wide range of discharge from cold water to hot water is required.
In most cases, it suffices to be able to discharge hot water at an appropriate temperature before and after, and either cold water or hot water, and conventional thermostat mixing valves that discharge cold water to hot water are not always easy-to-use mixing plugs regardless of usage conditions.

The present invention has been made in view of the above problems of the prior art, and its purpose is to provide easy operation, less risk of erroneous operation, high safety, and most suitable for use conditions. It is to provide a systematic mixing stopper that can be easily configured.
