Abstract

PURPOSE:To increase massage effect upon using a shower, by a method wherein an output hot-water temperature is changed with adequate timing, by the signal of a signal generating unit while the temperature width of the signal is changed arbitrarily by a setting unit, upon controlling the hot-water temperature of a hot-water supplying device. CONSTITUTION:When the supply of water is started, water, flowing into a water volume controller 1, flows into a heat exchanger 12, then, is heated by a heating device 21 and is supplied to the outside of the device through a hot water discharging pipe 13. When a hot-water temperature is risen up by the combustion of the heating device 21, the hot-water temperature is detected by a discharging hot-water temperature detector 30 and is compared with the signal of a discharging hot-water temperature setting unit to regulate electric current to the coil 27 of a temperature controller 20 and displace a valve body 25 through a plunger 28. When a signal generating unit is operated by an user or automatically after the hot-water temperature is stabilized, the signal of a tap, selected by a changeover switch, is added to the signal of the discharging hot-water temperature setting unit whereby the discharging hot water temperature is changed with adequate timing. The discharging hot-water temperature is changed time by time in such a manner, therefore, comfortable stimulation may be obtained when the hot water is used for showering and massage effect may be provided.

Description

[Detailed description of the invention] Industrial applications The present invention relates to hot water temperature control in a water heater.

BACKGROUND OF THE INVENTION Means for detecting the hot water temperature and adjusting the gas and water quantities are already known in the field of water heaters.

As shown in Fig. 4, it has a burner A, a fuel control valve B, and a heat exchanger C, and includes a temperature sensor that detects the hot water temperature and a comparator E that compares the output of the temperature setting device. The control valve F and the fuel control valve B of the flow passage are controlled according to the output of the control valve E.

Problems to be Solved by the Invention However, in the above-mentioned configuration, the amount of water and hot water temperature are constant during normal operation, and the amount of water and the hot water temperature are not changed over time. Therefore, if a certain amount of stimulation, such as showering, is preferred, regular stimulation can quickly become habituated, and especially when trying to obtain the pine surge effect by showering, the effect quickly wears off. 0 The present invention aims to enhance the pine surge effect in the shower.

Means for Solving the Problems In order to solve the above problems, the water heater of the present invention includes a temperature controller that controls the hot water temperature in response to a signal from a hot water temperature detector, and a temperature controller that controls the temperature of hot water that changes over time. It consists of a signal generating section that sends out a signal to the user, and a setting section that arbitrarily varies the range of change in the signal.

Function: With the above-described configuration, the hot water supply device of the present invention changes the outlet temperature over time based on the signal from the signal generating section, and further changes the range of change in the signal, that is, the temperature range, arbitrarily using the setting section.

Example An embodiment of the present invention will be described with reference to FIG.

1 is a water flow controller, and water enters the valve chamber 3 from the inflow path 2, passes through the gap between the control valve 4 and the control hole 5, and flows into the primary chamber 6.

7 is a diaphragm A (pressure receiving body) that operates together with the control valve, and the other side forms a double chamber 8, and the secondary chamber 8 has a control spring 9 that biases it toward the primary chamber 6. . - The water flowing into the next chamber 6 is transferred to the heat exchanger 1 through the valve hole 11 of the water flow control valve lO.
2 and is heated, and then supplied to the outlet pipe 13. The downstream side of the water flow control valve 10 is led to the secondary chamber 8 through a communication hole 14 .

The water flow control valve lO is driven by a drive device 17 consisting of a gear 15 and a motor 16. The position of the valve hole 11 changes as the water t1 regulating valve lO rotates, and the relationship between the differential pressure and the amount of water passing through the valve hole 11 changes, and the differential pressure acts on the diaphragm A7 to drive the control valve 4.

On the other hand, fuel flows in through the fuel supply path 19 and is supplied from the temperature controller 20 to the heating device 21, which heats the heat exchanger 12. The temperature controller 20 is composed of a valve body 22 and a casing 23, and has a control valve hole 24 in the valve body 22. The valve body 25 is displaced together with a diaphragm B26, and the diaphragm B26 is displaced by the current of the coil 27 during the plunge. 28.

The pressure-receiving areas of the diaphragm B26 and the valve body 25 are approximately equal, and the fuel pressure is controlled by the force exerted by the controlled pressure of the fuel on the valve body 25 and the electromagnetic force of the plunger 28 and the coil 27. Ru. A hot water supply controller 29 receives a signal from a hot water temperature detector 3o provided in the hot water pipe 13, and outputs the signal to the coil 27 of the temperature controller 20.

In the block diagram of FIG. 2, the hot water supply controller 29 includes a hot water temperature setting section 31, a temperature control section 32, a signal generation section 33, and a setting section 34. The hot water temperature is controlled by a hot water temperature setting unit 31 consisting of a variable resistor and the like and a hot water temperature detector 3.
Each signal of
Bring the hot water temperature closer to the set temperature. The signal generating section 33 sends out a signal that temporally changes the signal from the hot water temperature setting section 31 from the tap a35 and the tap b36. tap a
Tap b35 sends a signal indicating a large variation in the temperature of the outlet water, and tap b36 sends a signal indicating a small variation in the temperature of the outlet water.

The setting section 34 includes a changeover switch 37 that selectively switches between tap a35 and tap b36.

Next, when water flow is started in Figure 0, which describes the operation, water that has flowed into the water flow controller 1 flows into the heat exchanger 12, is heated by the heating device 21, and is supplied to the outside from the hot water outlet pipe 13. Ru. As the water flows, combustion starts in the heating device 21, and the temperature of the hot water rises.
is detected and compared with the signal from the hot water outlet temperature setting unit 31, and the current to the coil 27 of the temperature controller 20 is adjusted so that the hot water outlet temperature becomes equal to the setting, and the valve body 25 is displaced via the plunger 28. After the water temperature becomes equal to the set temperature and becomes stable, the signal generator 3 is activated by the user or automatically.
When 3 is operated 4, the signal generating section 33 generates a tamper a3.
5 and tap b36, and the signal of the tap selected by the changeover switch 37 of the setting section 34 is added to the signal of the hot water temperature setting section 31. Therefore, the hot water outlet temperature setting changes over time, and as described above, the hot water outlet temperature is controlled to be equal to the hot water outlet temperature setting, and the outlet hot water temperature changes over time as shown in FIG.

As the hot water temperature changes in this way, when used in the shower, it provides a pleasant stimulation and produces a pine surge effect.

Effects of the Invention As described above, the present invention provides a temperature controller that controls the hot water temperature in response to a signal from a hot water temperature detector, a signal generator that sends a temporally changing signal to the temperature controller, and a signal generator that controls the temperature of hot water according to a signal from a hot water temperature detector. Since the shower head is equipped with a setting part that can arbitrarily vary the width, the hot water temperature can be changed over time in any width, and a pine surge effect due to stimulation caused by a comfortable temperature change can be provided when using the shower.
