The present invention relates to a gas water heater for domestic or commercial use that automatically controls the hot water temperature.

ストが著しく高くなる欠点があつた。(Prior art) Gas water heaters that have been commonly used are:
The automatic water pressure gas valve and the water volume adjustment valve (modulation needle valve) respond to the water supply pressure via the diaphragm, allowing the amount of gas supplied to the main burner to be controlled in proportion to the amount of water supplied to the heat exchanger. Therefore, it does not function at all in response to changes in the temperature of the water supply. Therefore, the water supply temperature directly influences the hot water supply temperature, and the hot water supply temperature becomes low during cold times such as winter, and becomes high during warm and hot times such as summer. Therefore, a system that senses the water supply temperature and increases or decreases the amount of water supplied to the heat exchanger to control the hot water supply temperature can be seen, for example, in Japanese Utility Model Application Publication No. 133747/1983, but these systems do not detect the temperature of the water supply system. Since a special adjustment mechanism such as a warm-type on-off valve is required, the structure becomes complicated and the number of parts increases, resulting in a significant increase in product cost.

ある。(Structure of the invention) The structure is such that the diaphragm 3 of the water pressure response device A is connected to a water flow rate regulating valve V via a temperature sensing element 9 which senses the temperature of the supplied water and is thermally deformed, and the water flow rate regulating valve V is connected to a heat exchanger B. This water heater is characterized by having an adjustment function to increase or decrease the amount of water supplied to the heat exchanger B, and in cold weather such as winter, the amount of water supplied to the heat exchanger B is reduced by narrowing the opening degree of the water volume adjustment valve V. In addition, during hot weather such as summer, the opening degree of the water volume adjustment valve V is widened to increase the amount of water supplied to the heat exchanger B, thereby making it possible to automatically control the hot water temperature.

In the drawing, 1 heats the heat exchanger B to heat the cold water flowing through the heat exchanger B to raise the temperature. The main burner A is a hydraulic response device for controlling the amount of gas supplied to the main burner 1 in proportion to the amount of water supplied to the heat exchanger B.
is divided into a primary chamber 2a and a secondary chamber 2b, and a gas passage 4 to the main burner 1 is provided on the secondary chamber side of the diaphragm 3.
A hydraulic automatic gas valve V 1 biased in the closing direction by a spring 5 is connected via a valve shaft 6, and a water volume adjustment valve V is connected to the primary chamber side of the diaphragm 3. V is inserted into a restricting hole 8 provided in a water supply waterway 7, so that it responds to water supply pressure through a diaphragm 3 together with a hydraulic automatic gas valve V1 .
Reference numeral 9 denotes a temperature sensing element 9 that senses the temperature of the water supply and operates the water flow regulating valve V. A supporting member 10 attached to the diaphragm 3 is deformably equipped with a bimetallic temperature sensing element 9 that can be curved into a dish shape. A water volume adjustment valve V is fixed to the thermosensor 9 made of bimetallic material, and when the temperature of the water supply is low, such as in winter, the thermosensor 9 made of bimetal senses this and deforms downward in the figure (see the solid line in Figure 2) to adjust the water volume. The water flow opening between the valve V and the throttle hole 8 is narrowed to reduce the amount of water supplied to the heat exchanger B. When the water supply temperature is high, such as in the summer, the bimetallic temperature sensing element 9 senses this and increases the (see the chain line in FIG. 2) to widen the water passage opening between the water volume adjustment valve V and the throttle hole 8 to increase the amount of water supplied to the heat exchanger B. In addition to the bimetal described above, the thermosensor 9 may be a thermally expandable body that expands and contracts by sensing changes in the temperature of the water supply, but is free in practice. In the figure, reference numeral 11 denotes a water supply pipe, which forms a water supply channel 7 that extends from the water supply pipe 11 to a water supply pipe 13 to the heat exchanger B via the primary chamber 2a of the diaphragm chamber 2 and the ventilate section 12. 14
15 is a gas introduction pipe, 15 is a communication pipe connecting the secondary chamber 2b of the diaphragm chamber 2 and the ventilate part 12, 16
1 is a hot water supply pipe, and 17 is an inner shell.
上記構成において、冬期等の寒冷時は水道水等
の水温は低いため感温体９がこれを感知して水量
調整弁Ｖを押し下げその通水開口を絞るために熱
交換器Ｂへの給水量は減じ、また、夏期等の暖暑

拡げるために熱交換器Ｂへの給水量は増大する。
したがつて、給水温度に高低変化があつても熱交

給湯温度が得られるのである。 In the above configuration, in cold weather such as winter, the temperature of water such as tap water is low, so the temperature sensing element 9 senses this and pushes down the water volume adjustment valve V to narrow the water flow opening, thereby reducing the amount of water supplied to the heat exchanger B. In addition, during hot and humid times such as summer, the temperature of tap water is high, so the temperature sensing element 9 senses this and lifts the water flow adjustment valve V to expand the water flow opening to the heat exchanger B. Water supply will increase.
Therefore, even if the water supply temperature changes, a constant water supply temperature can always be obtained with the same gas valve opening without causing any fluctuation in the amount of gas supplied to the main burner 1 that heats the heat exchanger B. It is.
