Description

Hot and cold water supply regulator

The present invention relates to a cold / hot water supply regulator, and more particularly, to a cold / hot water supply controller for safe and convenient use of an infant, an elderly person, an uncomfortable patient, or a disabled person.

Generally, waterworks are installed in various buildings such as homes and offices to guide water and sewage to obtain water necessary for living.

In the capital, cold water is supplied to the building, and boilers installed in the building or hot water supplied from outside are supplied. The water supplied by the water supply system is supplied to the boiler of each building and then transferred by different pipes, and they are mixed at a desired place and taken out as water of a desired temperature.

As an apparatus for regulating the supply of cold water and hot water, Korean Patent Laid-Open No. 10-2003-0063771 discloses an intermittent valve having a function of controlling the temperature of cold and hot water. In order to separately obtain cold water and hot water, A main body having a mounting portion formed with a water inlet at one side thereof; Hot water is mixed with hot water received at one side of the inlet hole so as to correspond to inlet ports formed independently of the cold and hot water, An intermittent plate A formed to be divided into a mixing groove; An intermittent groove is formed to be in tight contact with the intermittent plate A so as to be rotatable in an angle and to transmit the water supplied to the inlet hole to the mixing groove on the surface facing the intermittent plate A, An intermittent plate B having an outlet hole; And an outflow nozzle which is installed so as to be rotatable at a predetermined angle with an installation part of the main body so that the intermittent plate A and the intermittent plate B are positioned inside and communicates with the outflow hole to allow water to flow out to the outside.

However, the method of confirming hot water or compound water discharged from most manual hot water supply regulators including the conventional technology is a method that the user must directly use after checking with the skin. As a result, , The risk of burns is very high due to the fact that the temperature is not precisely ascertained, and it is exposed to such danger in infants, elderly, handicapped people or patients who are uncomfortable to use. Especially, in the home where infants and toddlers are raised, the guardian must always be present, and there is a big difference between the temperature felt by adults and the temperature felt by infants and children, and the risk of burns becomes very great.

In order to solve such a problem, the automatic hot water controller for automatically controlling the temperature of the hot water has an advantage that the operation and the setting can be changed as desired by the user. However, there is a risk that hot water and compounding water may come out even at a high temperature due to the inoperability of the user, and the convenience is satisfied, but the safety is still low, so that a safety accident may occur. Also, due to the size of the panel that can not be seen at a glance, it is difficult for the user to check it from a long distance. In order to check, it is necessary to check the user from the shower or water. In addition, when cold water or hot water is used in other waterworks, the water pressure is lowered and the water pressure of the shower is lowered at the same time, and it is difficult to replace the shower water. The hot water caused by the use of excessive hot water causes environmental pollution due to excessive use of heat. It causes difficulty in operating when the power of the battery is low due to the use of the internal battery, and can not reduce the size, .

In order to solve the problems of the prior art as described above, the present invention is intended for safe and convenient use of infants, elderly people, uncomfortable patients, disabled persons, etc., It simplifies the use of the shower to reduce the inconvenience, reduces the water consumption by reducing excessive use of hot water due to immaturity, economically, informs the user of the time of use and promotes skin health, and when falling due to slipping in the bathroom, In case of long-term use of the protector's mobile phone, it will alert the inside of the bathroom to safety accidents, reduce the damage to human life, increase the economic efficiency by reducing the waste of energy such as hot water or boiler when using hot water, It is aimed at improving environmental problems.
