つた。(Prior Art) In a gas water heater, the temperature of water supplied, such as tap water, directly affects the hot water temperature, and the hot water temperature decreases during cold times such as winter, and rises during hot and warm times such as summer. Therefore, a temperature-sensitive on-off valve that senses the water supply temperature and automatically opens and closes is installed in the bypass path connecting the governor room and the downstream side of the ventilator. The valve is closed to reduce the amount of water supplied to the bypass passage, increasing the gas input that increases the water supply pressure to the governor room, and in hot weather such as summer when the water supply temperature is high, the temperature-sensitive shut-off valve is opened to reduce the amount of water supplied to the bypass passage. For example, Japanese Utility Model Application Publication No. 133747/1987 automatically controls the outlet temperature to a preset temperature without affecting the water supply temperature by increasing the amount of water supplied to the water supply and reducing the gas input due to the drop in water supply pressure. It is well known as seen in . However, the one described in Japanese Utility Model Application Publication No. 58-133747 is a temperature-sensitive opening/closing type that automatically opens and closes by detecting the water temperature of the water inflow path, which is connected to a bypass path that branches from the water inflow path and joins downstream of the ventilate. Since a valve is provided, the temperature-sensitive on-off valve is open most of the time during warm weather such as spring, summer, and autumn, except for cold temples during winter, so water is supplied from the bypass path almost all year round. . Therefore, since the bypass passage is equipped with a temperature-sensitive on-off valve, there is a drawback that the pressure loss is extremely large when the maximum amount of water is used in warm and hot weather.

The object of the present invention is to provide a gas water heater that makes it possible to finely adjust the water supply amount by providing a hot water outlet temperature adjustment valve in parallel with the temperature-sensitive on-off valve, thereby reducing changes in the hot water outlet temperature in response to fluctuations in the water supply temperature. .

きるものである。 In the above configuration, in cold weather such as winter, the temperature of water supplied such as tap water is low, so the temperature-sensitive on-off valve V2 senses this and closes, and the water supply to the heat exchanger B is routed through the bypass path 5 and the hot water temperature adjustment valve. It is supplied from the water supply channel 3 depending on the opening degree of V1 . At this time, since the water supply channel 3 is closed by the temperature-sensitive on-off valve V2 , the differential pressure between the primary chamber 2a and the secondary chamber 2b of the diaphragm chamber 2 increases, and the diaphragm 6 is activated by the water supply pressure. (in the drawing) increases the opening of the hydraulic automatic gas valve V4 linked via the valve stem 8 to increase the amount of gas supplied to the main burner 1, and increases the gas input to increase the water pressure. Promote heating and temperature increase. At this time, the amount of water supplied from the bypass path 5 is automatically controlled by the balance valve V3 in response to the water supply pressure, so the amount of water supplied to the heat exchanger B hardly changes. In addition, during warm and hot weather such as summer, the temperature of water supplied such as tap water is high, so the temperature-sensitive on-off valve V 2 senses this and opens, and the water supply to the heat exchanger B is routed through the bypass path 5 and the hot water temperature adjustment valve.
V 1 and the water supply channel 3 depending on the opening degree of the temperature-sensitive on-off valve V 2 , the swell effect of the temperature-sensitive on-off valve V 2 is reduced, the differential pressure in the diaphragm chamber 2 is also reduced, and the diaphragm 6 is pressed down by the spring 9 (in the drawing), and the opening of the hydraulic automatic gas valve V4, which is linked via the valve stem 8, is reduced to reduce the amount of gas supplied to the main burner 1, and the gas input is reduced. Heating is performed to raise the temperature. Also at this time, the amount of water supplied from the bypass path 5 is automatically controlled by the balance valve V3 in response to the water supply pressure, so the amount of water supplied to the heat exchanger B remains unchanged. Since the gas input is controlled depending on the temperature of the water supply, it is possible to keep the temperature of the hot water constant.

整が可能である。(Effects of the invention) As explained above, this invention provides a hot water temperature control valve and a temperature-sensitive on-off valve between the primary chamber of the diaphragm chamber of the water supply channel and the ventilary part, and Since it is connected to the downstream side by a bypass, the gas input is controlled according to changes in the water supply temperature, and the hot water temperature is automatically controlled.There is also no pressure loss in the bypass path, which is used most of the year, so when the maximum water flow is used. The pressure loss can be made extremely small, and the amount of water supplied can be finely adjusted using the hot water temperature adjustment valve and the temperature-sensitive on-off valve.
