Abstract

PURPOSE:To provide a massage effect by means of changing the flow rate at the time of shower usage by actuating an actuator to change the flow rate with time which modulates the flow rate setting of a flow rate controller by a signal which varies with time that controls the flow rate in a heat exchanger. CONSTITUTION:A flow rate controller 1 having an actuator 17 is connected to a heat exchanger 11, and a heater 20 for the heat exchanger 11 and a heater controller 19 for said heater 20 are provided. While the temperature of the delivered hot water is detected by a temperature sensor 12, a hot water supply controller 21 outputs a signal to a flow rate controller 1 to switch a variable control of flow rate with time and a contant flow rate control back and forth over a desired time period. That is, the actuator which modulates the flow rate setting of the flow rate controller is actuted by a signal which varies with time so that the flow rate may vary with time, and as a result a message effect is provided at the time of the shower usage by the flow rate change.

Description

[Detailed description of the invention] Industry”-1 Usage field The present invention relates to a water heater system J+.

Configuration of conventional example and its problems Water restriction of conventional water heater (F41 is only for guaranteeing hot water temperature, and during normal use, constant water LI at a constant rush rate)
Only F hot water was supplied. Therefore, if a certain amount of stimulation is preferred, such as in the shower, the user will quickly become accustomed to the constant stimulation. Particularly when trying to obtain the pine surge effect by taking a shower, the effect wears off quickly.

1:1 aspect of the invention The present invention changes the amount of water in the water heater over time to create a pine surge effect when using a shower.

Structure of the Invention In order to achieve this object, the present invention comprises: a water flow control device having a drive device; a heat exchanger communicating with the water; a heating device for the heat exchanger; a heating controller for the heating device; a temperature detector for detecting the hot water temperature;
The hot water supply controller is configured to output a signal for temporally varying the driving device and a signal for stopping the fluctuation of the driving device for a predetermined period of time to maintain a preset state to the water limiter.

With this configuration, the hot water flow rate fluctuates between 11 and 1,
A constant fnf, which is set only during a certain time period, is 1t.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In FIG. 1, reference numeral 1 indicates a water quantity static control 2g, and water enters the valve chamber 3 from the inflow path 2, passes through the gap between the side diagonal valve 4 and the antibacterial hole 5, and flows into the cutout 6. Reference numeral 7 denotes a diaphragm which operates together with the control valve 4, and the other side forms a secondary chamber 8, and the secondary chamber 8 has a control spring 9 that biases it toward the one-notch 6 side.

-The water flowing into the missing part 6 is the valve hole 10a of the water flow control valve 1o.
is supplied to the heat exchanger 11 and heated, and the temperature sensor 1
The hot water is supplied to the outlet pipe 13 having the hot water. The downstream side of the water sprinkling control valve 10 is led to the secondary chamber 8 through a communication hole 14 .

The water sprinkling control valve 10 is driven by a driving device 1Y consisting of a gear 15 and a motor 16. The rotation of the water flow control valve 1o changes the position of the valve hole 10a, changing the relationship between the differential pressure and the amount of water passing through the valve hole 10a, and this differential pressure acts on the diaphragm 7 to drive the control valve 4. Water flow control valve 1
The rotation angle of 0 is detected by position detection, 11 and 17a.

- The power gas passes through the heating side device 19 from the gas supply path 18 and is burned in the heating device 20 to heat the heat exchanger 11. 21
is a hot water supply controller that inputs signals from the temperature detector 12 and position detector 17a, and outputs them to the 1 drive device 17 and the heating controller 19.

In the block diagram of FIG. 2, the hot water supply controller 21 includes a hot water temperature setting section 22, a heating control section 23, a signal generating section 24, and a holding section 25. The holding part 25 is a timer part 26
and the drive device setting section 27.

It is composed of a position detector 17a and a changeover switch 28.

The hot water temperature side slope is calculated by the heating control unit 23, which calculates respective signals from the hot water temperature setting unit 22 and the temperature detection 2”+12, which are composed of variable resistors, etc., and calculates the well-known PID!till
ffl VC Yo) Thea JJl heat ff1J 11g
819 wo, @/do1. By adjusting the calorific value of the heating device 20, the temperature of hot water discharged from the heat exchanger 11 is kept constant. The signal generating section 24 generates a signal that changes over time, and in response to the signal, the 1 drive device 17 rotates the water volume control valve 10 of the water volume controller 1 to change the water volume. The changeover switch 28 cuts off the signal from the signal generation section 24 to the drive device 17 and connects the drive device setting section 29 and the drive device 17 when the timer section 26 operates.

The drive device setting section 31 drives the drive device 17 based on the magnitude of the deviation signal between the signal from the position detector 17a and a preset state.

Next, the operation will be explained. When the power is turned on and water starts flowing, the heating device 20 starts heating 1:l'/l, and after a slight delay, the hot water temperature rises. The respective indicators of the hot spring water temperature determining unit 22 and the temperature detector 12 are operated by the heating control unit 23, and the heating control unit 19 is assisted to make the hot water temperature equal to the set temperature.

If the operation setting of the timer part 26 is set to 1 for a predetermined period of time from the start of hot water supply, the amount of water will change according to the drive device setting F.
A signal from the ilS27 is transmitted to the drive device 17 to rotate the water flow control valve 1o to the set position. Water flow control valve 10
The throttle of the valve hole 10a changes by 0 rotation, and the valve hole 10a changes.
The differential pressure acts on the diaphragm 7 to drive the control valve 4,
The water volume becomes the set value. When the predetermined time comes, the timer part 26
When the operation of the signal generator 24 is completed, the changeover switch 28
A change signal is transmitted to the drive device 17 to rotate or reverse the water flow control valve 1o. Therefore, the amount of water starts to fluctuate as shown in FIG.

Effects of the Invention L-), ]-As described above, the water heater of the present invention provides the following effects.

(1) A time-varying signal drives a drive device that varies the set water volume of a water flow controller that controls the amount of water flowing through the heat exchanger, changing the water volume over time. It can sometimes give a pine surge effect that changes the amount of water.

(2) It is possible to stop the change in the water volume for a certain period of time and maintain it at the set water hl'. Maximum water: 1; - allows you to bathe for a fixed period of time, is comfortable and convenient to use.
