【考案の詳細な説明】 この考案は貯湯式給湯器に関する。[Detailed explanation of the idea] This invention relates to a hot water storage type water heater.
従来、貯湯槽を備えた給湯器の燃焼制御方式は

方式では設定湯温維持のため止水時でも通電して
熱源をオン、オフする必要があり甚だ不経済であ
つた。 Conventionally, most combustion control methods for water heaters equipped with a hot water storage tank have been based on a method that detects the water temperature in the hot water storage tank and turns on and off the heat source (for example,
Publication No. 180340). This is because if a water flow or water pressure sensing type is used, such as in an instantaneous water heater, the temperature of the water will rise slowly and will be inconvenient to use. However, in order to maintain the set water temperature, the hot water temperature detection method requires electricity to be turned on and off to turn the heat source on and off even when the water is turned off, which is extremely uneconomical.

して経済性を高めたものである。 This invention aims to solve the above-mentioned problems of the conventional technology, in a water heater equipped with a hot water storage tank that stores high-temperature hot water obtained by heating water in an endothermic pipe with a gas burner. A temperature-sensing flow restrictor is installed in the pipe, and a cold water supply pipe branched from the water supply channel is connected to the flow restrictor, and when the hot water temperature is below the set temperature, the amount of hot water is restricted, and the pipe is connected to the cold water supply pipe. and a water flow or water pressure switch is provided in the water supply channel, and control is performed to close the gas valve by giving priority to the combustion-off operation of the gas burner by the switch over the combustion-on signal detected by the hot water temperature detection in the hot water storage tank. By having a configuration with a container, even if a water flow detection type is used, by restricting the amount of hot water when the water temperature rises (at the beginning of use), high-temperature water can be obtained from the moment the water temperature rises, making it easy to use. By giving priority to the combustion-off operation of the gas burner by the water flow or water pressure switch over the combustion-on signal by detecting the temperature of hot water in the hot water storage tank, wasteful use of the heat source when the water is stopped is eliminated and economical efficiency is improved.

なしている。 An embodiment of this invention will be described below based on the drawings. In the drawings, 1 is an upper hot water storage tank, 2 is a lower hot water storage tank, 3 is a heat absorption pipe with fins, and the upper hot water storage tank 1 is
The lower hot water storage tank 2 is connected to the finned heat absorption pipe 3 and the circulation pipes (not shown) at the bottom on both sides, and by heating the finned heat absorption pipe 3 with the gas burner 4, the water inside the finned heat absorption pipe 3 is transferred to the lower hot water storage tank 2. The hot water is circulated through the path of → heat absorption pipe 3 → upper hot water storage tank 1 → circulation pipe → lower hot water storage tank 2, heated and heated, and stored in the upper hot water storage tank 1. Therefore, the upper hot water storage tank 1 stores high temperature hot water, and the lower hot water storage tank 2 stores low temperature hot water. Reference numeral 5 denotes a hot water outlet pipe drawn out from the top of the upper hot water storage tank 1, and a temperature-sensing type flow rate limiter 6 for limiting the amount of hot water dispensed is provided in the middle of the pipe. As this flow rate restrictor 6, a known type such as an automixer or a thermoelement is used. Reference numeral 7 denotes a water supply pipe to the lower hot water storage tank 2, which is branched from and connected to the water supply pipe 8, and the other branch water supply pipe 9 is connected to the flow restrictor 6.
If the hot water temperature from the hot water outlet pipe 5 is above the set temperature, cold water from the water supply pipe 9 is mixed to the desired temperature, and if the water temperature is below the set temperature, the cold water from the water supply pipe 9 is cut off. Furthermore, the amount of hot water passing through is restricted to promote temperature rise due to burner heating. Reference numeral 10 denotes a water flow or water pressure switch provided in the water supply conduit 8, and its ON signal passes through the controller 12 to open the gas valve 13 provided in the gas passage to the gas burner 4 to ignite the gas burner 4, and the OFF signal causes the gas burner to switch off. This is to turn off the combustion of step 4. Reference numeral 11 denotes a hot water temperature sensing thermostat inserted into the upper hot water storage tank 1, and the ON signal of this thermostat 11 is controlled by the controller 12 as a signal to cause the gas burner 4 to burn when the water flow or water pressure switch 10 is OFF. However, the off signal is the water flow or water pressure switch 1.
Safety is ensured by giving priority to the 0 ON signal.

ある。 In the above configuration, when the tap (not shown) is opened, a water flow as shown by the arrow is generated, the water flow or the water pressure switch 10 is turned on, the gas burner 4 is ignited, and the finned heat absorption pipe 3 is heated. ), the stored hot water in the upper hot water storage tank 1 flows out into the hot water outlet pipe 5. However, when the hot water temperature at the time of startup is lower than the set temperature, the temperature-sensing flow restrictor 6 installed at the hot water outlet temperature 5 is activated to restrict the amount of hot water passing through and accelerate the heating temperature by the gas burner 4. High-temperature hot water can be obtained from the beginning of startup. At this time, communication with the branch water supply pipe 9 is cut off. Also,
If the hot water temperature sensed by the flow restrictor 6 is higher than the set temperature, it communicates with the branch water supply pipe 9, mixes an appropriate amount of cold water from the water supply pipe 9, and discharges hot water at the set temperature.

号に優先してガス弁１３を閉止するものである。 Naturally, the burner is extinguished while the hot water supply is stopped, but even if the thermostat 11 installed in the upper hot water storage tank 1 senses a drop in the hot water temperature and issues a combustion on signal, the controller 12 will control the water flow or water pressure switch 10. Since the off signal is configured to have priority, the gas valve 13 remains closed via the restrictor 12. Further, if the thermostat 11 detects an abnormally high temperature for some reason during hot water dispensing, the controller 12 closes the gas valve 13 with priority over the ON signal for burning the gas burner 4 of the water flow or water pressure switch 10.

がなくなり経済的である。 As explained above, this device uses a temperature-sensing type flow restrictor 6 to reduce the amount of hot water at the time of start-up and to stop the mixing of cold water when the hot water temperature is below the set temperature. Even if this method is adopted, hot water can be obtained from the start, making it easy to use. In addition, the water flow or water pressure is detected by the water flow or water pressure switch 10, and the combustion off operation by the switch is prioritized over the combustion on signal from the hot water temperature detection in the hot water storage tank, which eliminates wasteful use of the heat source when the water is stopped, making it economical. be.
