Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temperature controller used for hot water supply pipes and the like, and an on-off valve with a timer switch.

[0002]

[Prior Art]

 Conventionally, as a means for preventing the temperature drop of the hot water supply at the initial stage of hot water supply, the heat insulating material of the hot water supply pipe for preventing heat release from the hot water supply pipe has been used.

[0003]

[Problems to be solved by the device]

 However, when the hot water tap is not used for a while and then the hot water tap is to be opened, for example, when the hot water tap is opened, especially when washing in the early morning such as in winter or when using hot water for shower at night. I feel annoyed and uncomfortable because hot water does not come out easily because the cold water stored in the hot water supply pipe comes out.

This is because the hot water remaining in the pipes of the hot water supply tap and the heat source transfers heat to the surrounding low temperature part by heat transfer or the like, and radiates heat.

If the length of the hot water supply pipe between the hot water tap and the heat source is long, it takes time for the hot water from the heat source to push out the cold residual water in the pipe, and to warm the pipe. Hot water does not come out. As a result, people using hot water were irritated, and cold water was mistakenly used. Similarly, in the case of piping for supplying cold water, it may happen that the desired temperature cannot be obtained.

An object of the present invention is to solve the above-mentioned conventional problems and to provide an on-off valve that prevents discomfort due to outflow of cold water at the beginning of hot water supply with a minimum equipment cost. Another object of the present invention is to provide an on-off valve that can immediately supply water having a desired water temperature to a wide range of uses.

[0007]

[Means and Actions for Solving the Problems]

 The gist of the present invention is to provide an on-off valve equipped with a temperature controller and a timer switch separately from the faucet in the hot water tap to discharge cold water at the initial stage of hot water supply and prevent low temperature hot water supply during use. Is. Alternatively, water that is close to the desired water temperature at the time of use is supplied immediately.

That is, the above object of the present invention is to provide a temperature controller that detects the water temperature in the pipe and opens and closes a switch that opens and closes the open / close valve according to the upper and lower set temperatures, and a power switch of the open / close valve circuit at a set time. The present invention is achieved by a temperature controller and an on-off valve with a timer switch, which comprises a timer switch that opens and closes and an on-off valve that opens and closes by the temperature controller.

In the present invention, the temperature controller that detects the water temperature in the pipe and opens and closes the switch that opens and closes the open / close valve according to the upper and lower set temperatures is a thermistor type, for example, 10 ° C. and 30 ° C. are the lower limits, respectively. The upper limit temperature can be freely set between them, the water temperature in the pipe is sensed, the open / close valve is opened below the lower limit temperature, and the open / close valve is closed above the upper limit temperature. However, if the invented on-off valve is used to control cold water, the on-off valve operation can be reversed.

In the present invention, the timer switch that opens and closes the power switch of the on-off valve circuit at the specified time is for opening and closing the power switch according to the set time for the operation of the on-off valve. Can turn on the power switch and turn off the power switch after that time.

The on-off valve that is opened and closed by the temperature controller of the present invention is preferably a solenoid valve that operates according to the setting of the temperature controller and the setting of the timer switch to open and close the current. The solenoid valve is opened and closed or closed and opened to let out or stop water.

However, the opening / closing valve of the present invention is not limited to the solenoid valve, and may be an electric type, a pneumatic type, or a hydraulic type.

The temperature controller and the on-off valve with a timer switch of the present invention are set on the hot water pipe near the hot water tap, but the position may be anywhere near the hot water tap, and it may be placed at a right angle to the side of the hot water tap. It may be installed with a branch pipe or installed in an invisible place in the wall, as it depends on the preference of the user.

The drainage of the temperature controller and the on-off valve with a timer switch of the present invention may be opened in the washbasin, connected separately to the drain pipe, or connected to another pipe to the water tank. Good. The temperature controller and the on-off valve with the timer switch according to the present invention may be used not only for the hot water supply pipe but also for the cold water supply pipe. It can also be used to prevent freezing of water pipes. In that case, by setting the temperature controller to around 0 ° C, it is possible to prevent freezing by draining the water in the pipe before it freezes and raising the temperature.

【Example】

 FIG. 1 shows a washbasin to which the temperature controller and the on-off valve with a timer switch of the present invention are applied.

At present, hot water from a heat source is normally used from the hot water tap 1 by the washbasin 3 and is drained through the wastewater pipe 6.

However, if hot water is not supplied for a long time, the temperature of the hot water in the hot water supply pipe 2 up to the heat source and the hot water tap 1 decreases to the external temperature due to heat transfer or the like. Therefore, a drain pipe 4 is newly provided between the pipe 2 and the hot water tap 1, and a temperature controller 7 and an opening / closing valve (solenoid valve) 5 with a timer switch 8 are installed. The water outlet of the solenoid valve 5 was connected to the waste water pipe 6 in this embodiment. However, it may be opened to the washbasin or connected to piping to another water tank.

The time when hot water is used is set by a timer switch, and the power switch 11 of the solenoid valve operation circuit 10 is turned on during that time. On the other hand, there is an open / close switch 12 that turns off at the upper limit temperature of the temperature controller and turns on at the lower limit temperature. When the power switch 11 is closed, the temperature controller itself opens and closes the solenoid valve. become.

As a result, the electromagnetic valve 5 is opened to drain the cold hot water in the pipe 2, and when the water temperature in the pipe reaches a certain temperature or higher, the electromagnetic valve closes and the drainage is stopped, so that the hot water tap 1 always keeps a certain temperature or higher. You will be able to supply hot water. Therefore, at the time of use, a certain amount of hot water is always supplied from the hot water tap.

When the hot water temperature is likely to drop at night in winter and is not used for a long period of time, wasteful water is drained. Therefore, the timer switch 8 is used to control the operation of the on-off valve 5 by the temperature controller 7 using hot water. Only when you expect to be frequent. (For example, there is no temperature control from 11:00 pm to 6:00 am.) For sudden use of hot water, such as at night, when the electricity in the washroom lights up It is also possible to turn on the power switch 11 and activate the on-off valve 5 by the temperature controller 7.

[0021]

[Effect of the device]

 According to the present invention, when hot water (cold water) is used, it is possible to immediately use water close to the hot water (cold water) temperature.

According to the method of the present invention, by using a timer switch, the timing for opening the on-off valve is set to a time when hot water is used, so that the on-off valve is not opened unnecessarily, fuel cost, water supply You can suppress the loss of your generation to a minimum.
