Abstract

The object of the present invention is to provide a temperature control system of a temperature suitable for mixing hot water and cold water.

If the temperature of the control water is higher than the set temperature, the cold water side is operated and the cold water is introduced into the water tank. If the temperature of the control water is lower than the set temperature, the hot water side is operated by operating the hot water side, A regulating water with a suitable temperature can be used and the waste of fuel due to the hot hot water can be reduced.

Description

On / cold mixed type temperature control system {omitted}

The present invention is an on / cold mixed type temperature control system for providing a temperature controllable water suitable for mixing hot water and cold water.

Conventionally, hot water from a hot water boiler can be showered by sensing the temperature of a person's hand by using the handle of a mixed water type faucet, and the temperature is changed according to the amount of water used, Few people do not feel uncomfortable with temperature control. Also, there is a problem of waste of fuel due to hot water spillage.

In order to solve the above inconveniences and problems, the present invention provides a regulated water with a constant temperature which is adjusted by mixing hot and cold water, so that the faucet can be turned on and the shower can be instantly made, the waste of fuel due to hot water can be reduced, And a temperature control system of a mixed type of hot and cold water.

1 is a perspective view showing the structure of the present invention. A hot water inlet 26 and a cold water inlet 27 are provided in a water tank 6 surrounded by a heat insulating material 5 and a hot water side electromagnetic wave valve 2 and a cold water side electromagnetic wave valve 2, And a digital temperature controller 29 to which a temperature sensor 7 is attached.

A pressure switch 3 is attached to prevent unnecessary operation of the hot water side electronic valve 1 and the cold water side electronic valve 2 when the control water is not used. A heater 8 for maintaining the temperature of the control water when the control water is not used and an adjustable water outlet 4 for letting out the control water are provided and a plurality of nozzles 11 12 to the hot water tank 6.

The operation principle will be described with reference to Fig.

When the temperature of the control water is set using the temperature setting button 9 of the digital temperature controller 27, the temperature sensor 7 senses the temperature. When the temperature of the control water is higher than the set temperature, The power is turned off from the common power line 14 to operate the cold water side electronic valve 2 so that the cold water waiting in the cold water connection port 25 flows into the water tank 6 to lower the temperature of the control water and when the temperature of the control water is low Power is outputted from the heater terminal line 16 and the common power line 14 to operate the hot water side electronic valve 1 to warm water waiting in the hot water connector 24 into the water tank 6 to lower the temperature of the control water . By repeating this operation, the temperature of the regulating water in the water tank 6 is kept constant. In addition, when the hot water is not used, one of the hot water side electromagnetic valve 1 and the cold water side electromagnetic valve 2 is operated to waste unnecessary electric power. In order to shut off the power of the both side electromagnetic valves, The power line 14 is disconnected.

Since the hot water does not flow when the hot water is not used, the power supply line of the electric heater 8 installed to prevent the temperature of the regulator from dropping is connected to the heater terminal line 16 and the common power line 14. Here, if the capacity of the electric heater 8 is increased, it may be an electric water heater.

A mechanical temperature controller may be used in place of the digital temperature controller 29 in the present invention.

FIG. 2 is a perspective view showing an embodiment of the present invention, which shows an appearance of a state in which the case 28 is covered, but it may be cylindrical in a large capacity. There are provided a liquid crystal 17 for knowing the temperature of the current control water, a control water temperature setting button 9 for controlling the control water temperature, a hot water connection port 24, a cold water connection port 25, A power plug 10 for supplying power is provided.

The hot and cold water mixed temperature control system of this invention can be attached to the hot and cold water outlet of the bath room, and can be used for shower only, or it can be attached to the boiler.

FIG. 3 is an embodiment using an electric wire for controlling the room temperature of the boiler, and the temperature of the water in the room can be adjusted in the room.

When the signal wire 22 is drawn out and connected to the room temperature controller wire 21 and the adjusting water temperature setting button 9 is installed in the room in the mixed warm and cold water temperature control system, Adjustable. The adjustable temperature setting button (9) can be integrated into the room temperature controller.

As described above, the hot / cold mixed type temperature control system of the present invention eliminates the inconvenience of temperature control during a shower and reduces the waste of fuel due to hot water overflow.

Claims (3)
