り、この間で湯温が調節できる。 In this conventional method, the interlocking relationship is large water volume -
It is set so that it can change from a small gas volume state to a small water volume - large gas volume state, with the former setting condition drawing out a large amount of low temperature hot water, and the latter setting condition drawing out a small amount of high temperature hot water. The water temperature can be adjusted during this time.
この場合、ガス量を一定にして水量のみを調節

操作により流量が調節される。 Next, when the first and second on-off valves 31 and 32 are closed, the bypass circuit 12 is cut off and the large flow rate circuit 22 is also cut off. As a result, the amount of gas flowing into the gas amount control valve 11 and the amount of water flowing into the gas amount control valve 21
The flow rate is adjusted by these operations in a state where the flow rate on the downstream side is restricted.

合つたものとなる。 By the way, in a gas burner, the maximum amount of gas that can be combusted is determined by the nozzle facing the burner, and the gas circuit 1 in the throttle state
Since the maximum flow rate of is set to a predetermined value below the flow rate set by the burner nozzle diameter,
In the gas circuit 1, in the adjustment range of the gas amount control valve 11, the gas flow rate is from a large flow rate below the maximum value to
Varies in the range of small flow rates. Furthermore, the second on-off valve 3
Since the flow rate of the water circuit 2 in the closed state of 2 was set to a predetermined value that is less than the minimum flow rate value when the second on-off valve 32 is in the open and non-throttled state, the amount of water in the water circuit 2 has decreased. Set to a constant flow rate value.
Therefore, the amount of hot water in the water heater is reduced, and the temperature of the water at this time meets the adjustment conditions of the gas amount adjustment valve 11.

る。 In addition to adjusting the hot water temperature only by adjusting the gas amount control valve 11 and the water amount control valve 21, the first and second on-off valves 3
By simultaneously operating the valves 1 and 32, it is possible to set the water volume to a small gas volume range where the gas volume can be adjusted. Therefore, by operating the first and second on-off valves 31 and 32, it is possible to set the hot water temperature according to the usage conditions. wasteful use of can be prevented.

The flow rate in each of the above states of the gas circuit 1 and the water circuit 2 is set to a predetermined value so that the hot water temperature set by the hot water temperature regulating device does not change when the valve 32 is in the closed state and when the valve is in the open state. This is what was set.

When valves 1 and 32 are closed and the water is in a low water flow state,
The hot water temperature is the same in both the normal use conditions in which the first and second on-off valves 31 and 32 are opened, and the hot water temperature display on the operating section of the hot water temperature adjustment device matches the hot water temperature in either use condition.
従つて、通常使用状態から小湯量状態に変えた
ときに湯温が変化する不都合が解消される。 Therefore, the inconvenience that the hot water temperature changes when changing from the normal usage state to the low water amount state is eliminated.

最大ガス量Q2に達し、以後は、前記操作量を多
くしても、ガス量は変化しない。 That is, since the first on-off valve 31 is in the open state, the amount of gas supplied to the burner 4 is added to the amount of gas flowing through the gas amount adjustment valve 11 and the amount of gas from the bypass circuit 12 . Therefore, at the zero point of the operation amount of the operation knob, the amount of gas supplied to the burner 4 is reduced to the minimum flow rate via the gas amount control valve 11 through the bypass circuit 12.
The minimum flow rate value Q 1 is added with the flow rate from
When the operation amount reaches the specific point P, it reaches the maximum gas amount Q2 set by the nozzle (not shown) corresponding to the burner 4, and from then on, even if the operation amount is increased, the gas The amount does not change.

As shown in the figure, the change in the opening of
In the following range, the maximum flow rate is set to Q5 , and when the manipulated variable increases beyond this, the flow rate decreases linearly, and the flow rate is set so that the minimum flow rate is Q4 at the maximum manipulated variable position of the operating knob.

Under these conditions, the water volume changes and the hot water temperature changes linearly.

The amount of gas supplied to the gas flow rate varies linearly within the adjustment range (minimum gas amount Q 0 to maximum gas amount Q 2 ) by the gas amount control valve 11, as shown by the broken line B in FIG.

示す。 On the other hand, the amount of water in the water circuit 2 is determined by the second orifice 24.
Since the flow rate set by is set to a water amount Q 3 which is less than the minimum water amount Q 4 that can be throttled by the water amount adjustment valve 21, regardless of the operation of this water amount adjustment valve 21, the flow rate is shown by the imaginary line B in the same figure. so that the water volume is constant
Q Set to 3 . Therefore, under conditions of constant water volume, the gas volume will change linearly, and the water temperature will also change.
A linear change is shown depending on the amount of operation of the operation knob 65.
以上のように、上記実施例のものでは、少い湯

When the operating part 40 provided in the figure is pulled, the leaf springs 7, 7 change to the state shown by the two-dot chain line in the same figure, and the first and second on-off valves 3
The valves 1 and 32 are in a non-throttled state with the valves open.

する。 Further, as a circuit configuration on the downstream side of the water flow control valve 21, a configuration as shown in FIG. 7 may be adopted. In this one, the second orifice 24 is formed in the second on-off valve 32 itself that opens and closes the flow path on the downstream side of the water flow control valve. Therefore, this second on-off valve 3
In the open state of No. 2, the flow path on the outer periphery of the second on-off valve 32 becomes the aforementioned large flow circuit 22, and the second on-off valve 32
The flow paths of the orifice 24 become the small flow rate circuit 23 and are arranged in parallel with each other, and the second on-off valve 32
When the valve is closed, the large flow rate circuit 22 is closed and only the second orifice 24, which becomes the small flow rate circuit, communicates. This functions in the same way as in the case of FIG. 1 above.

置。[Scope of Claims] 1. A hot water temperature regulating device that adjusts the temperature of hot water by interlocking a water flow regulating valve 21 inserted into the water circuit 2 and a gas flow regulating valve 11 inserted into the gas circuit 1. The gas circuit 1 is provided with a bypass circuit 12 that bypasses the gas amount control valve 11, a first orifice 13 provided in this bypass circuit, and a first opening/closing valve 31 that opens and closes the bypass circuit 12, The water circuit 2 is provided with a flow path consisting of a large flow rate circuit 22 and a small flow rate circuit 23 that are arranged in parallel with each other, and a second on-off valve 32 that opens and closes the large flow rate circuit 22, which is provided on the downstream side of the water flow control valve 21. These first and second
The on-off valves 31 and 32 are configured to be set in two states, a closed state and an open state, and can be operated simultaneously from the outside to the same state, so that the maximum of the gas circuit 1 when the first on-off valve 31 is in the closed state is The flow rate is set to a predetermined value below the flow rate set by the nozzle diameter of the burner, and the flow rate of the water circuit 2, which is set only by the small flow rate circuit 23, is set by the second on-off valve 3.
A water temperature adjustment device for a gas water heater that is set to a predetermined value that is less than the minimum flow rate value when the valve 2 is in an open state. 2. The closed state of the first and second on-off valves 31 and 32,
The gas according to claim 1, wherein the flow rate in each state of the gas circuit 1 and the water circuit 2 is set to a predetermined value so that the hot water temperature set by the hot water temperature adjustment device does not change depending on the valve open state. Water temperature adjustment device for water heater.
