Abstract

PURPOSE:To maintain a massage effect during taking a shower bath, by changing the spectrum of power in the temperature in effluent hot-water so as to be inversely proportional to the frequency. CONSTITUTION:When a switch 18 is turned off after the temperature in hot- water is heightened up to the equal temperature to the set temperature and is stabilized, a signal is outputted from a signal memory 19, being amplified by a pulse generator 18, and is added to the signal in a temperature setter 17 for effluent hot-water. The signal memory 19 stores the signals which are needed to have the spectrum of power, which is changed by the change in the temperature in hot-water, change to be inversely proportional to the frequency, and generates signals one after another during the operation. By these signals, the temperature in effluent hot-water is to be fluctuated 1/f by time, and is controlled, in the same manner as the temperature in effluent hot-water is set. If the hot-water is used for shower bathing, it gives comfortable stimulation to a human body, and a massage effect can be obtained therefrom.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to hot water temperature control in a water heater. Conventional Example δ Configuration and Problems A hot water heater detects the hot water temperature and automatically controls the combustion amount to control the hot water temperature. It is already known that temperature can be stabilized, but if it is preferred to simply supply hot water at a constant temperature during steady-state conditions, regular stimulation will quickly cause habituation.

Especially when trying to obtain the pine surge effect by taking a shower, the effect wears off quickly.

OBJECTS OF THE INVENTION The present invention maintains the pine surge effect when using a shower by changing the power spectrum of the hot water temperature of a water heater in inverse proportion to the frequency.

Structure of the Invention In order to achieve this object, the present invention detects the outlet temperature of the hot water of the heat exchanger heated by the heating device with a temperature detector, controls the heating controller to adjust the amount of heating, and keeps the outlet temperature constant. In addition to controlling the frequency, the signal from the signal generating section is applied to the outlet hot water temperature setting section to change the worth vector of the outlet hot water temperature so as to be inversely proportional to the frequency.

Description of examples An embodiment of the present invention will be described with reference to the accompanying drawings.

The hot water is supplied from the inlet heat exchanger 3 to the outside through the outlet pipe 4. Fuel flows in from the fuel supply path 5 and is supplied to the heating device 7 by the heating controller and the like, and the heat generated by the heating device 7 heats the heat exchanger 3. The heating controller 6 consists of a valve body 8 and a casing 9, has a valve hole 10 in the valve body 8, the valve body 11 is displaced integrally with a diaphragm 12, and the diaphragm 12 is connected to the coil 1.
It is displaced by a plunger 14 which is displaced by a current of 3. The pressure receiving areas of the diaphragm 12 and the valve body 11 are approximately equal to 1, and the fuel pressure is controlled by balancing the force exerted on the valve body 11 by the controlled pressure of the fuel and the electromagnetic force and magnetic force of the plunger 14 and the coil 13. be done. 15
is a hot water supply controller, which is a hot water temperature sensor 1 installed in a hot water tap pipe 4.
6 is input and output to the coil 13 of the heating controller 6.

In the block diagram of FIG. 2, the hot water supply controller 15 includes a hot water outlet temperature setting section 17, a signal generating section 18, a signal storage section 19, a heating control section 20, and a switch 21, and the heating control section 20 is a hot water outlet temperature setting section. The deviation between the section 17 and the hot water temperature detector 16 is calculated, known PID control is performed to drive the heating controller 6, and the heating amount of the heating device 7 is adjusted to keep the hot water temperature of the heat exchanger 3 constant. . The signal generating section 18 receives the signal from the signal storage section 19, adds it to the signal from the hot water temperature setting section 17, and changes the temperature setting over time so that the power spectrum of the temperature change is inversely proportional to the frequency. The switch 21 turns the signal generator 18 on and off.

Next, the operation will be explained. When the power is turned on and water supply starts, the heating device 7 starts combustion and heats the heat exchanger 3, and the temperature of the hot water rises. It is compared with the signal, and the current to the coil 13 of the heating controller 6 is adjusted so that the hot water temperature becomes equal to the setting, and the valve body 11 is displaced via the plunger 14.

After the hot water temperature becomes equal to the set temperature and stabilizes, switch 18 is turned on.
When closed, a signal is sent out from the signal storage section 1e, amplified by the signal generator 18, and added to the signal from the hot water temperature setting section 17. The signal storage unit 19 stores the power spectrum of the water temperature change at the frequency ('), which is inversely proportional to the 1a bow, and generates signals one after another during operation (hereinafter referred to as 1/f fluctuation of the water temperature). , the hot water temperature is 1 in terms of time.
As mentioned above, the hot water temperature is controlled to be equal to the hot water concentration setting, and the hot water temperature changes over time as shown in Figure 3, and as shown in Figure 4, it fluctuates by 1/f. becomes. If used in the shower, it will stimulate the sinuses and have a pine surge effect.

It is known that fluctuations with this 1/f fluctuation are closely related to human sensations, and fluctuations in brain waves and heartbeat cycles have 1/f fluctuations. Furthermore, the acoustic power of pleasant music and the power spectrum of frequency fluctuations are also proportional to 1/f. Based on this knowledge, there are also examples of applying 1/f fluctuations to the strength and interval of the current applied when relieving pain such as neuralgia, thereby obtaining an effect. That is, 1/f
Fluctuations are said to prevent the human body from becoming accustomed to the stimulus, maintain freshness, and match the rhythm of human sensations.

In this embodiment, a fuel control valve is shown as the heating controller 6, but if the heating device is an electric heater, a power regulator may be used.

Effects of the Invention As described above, the present invention uses a temperature detector to detect the outlet temperature of the heat exchanger heated by the heating device, and adjusts the heating device by the heating controller so that the outlet temperature is equal to the temperature setting. ,
By varying the hot water temperature setting by the signal generating part in an inversely proportional relationship to the power spectrum and frequency of the water temperature change, it is possible to give a pine surge effect when using the shower and to maintain a comfortable shower.
