Description

[Detailed description of the invention] This invention relates to water heaters, and allows the temperature regulator of the water heater to operate more quickly and reliably to prevent accidents caused by empty water when there is no water in the water heater. It was designed so that it could be done.

Embodiments will be described below with reference to the drawings. Reference numeral 1 denotes a hot water machine, which has a water chamber 4 having a double-walled structure with an inner wall 2 and an outer wall 3.

5 is a combustion chamber, 6 is a burner, 7 is an exhaust pipe, 8 is a water supply pipe, 9
is the outlet pipe.

Reference numeral 10 denotes a water reservoir portion in which a part of the inner wall 2 is bulged toward the combustion chamber 5 side, and the inner wall 2 is bulged out integrally as shown in FIG. 2, or as shown in FIG. A portion may be opened and a separate water reservoir portion 10 may be provided by welding to this opening.

Reference numeral 11 denotes a temperature regulator which penetrates the outer wall 3 and faces the water reservoir 10. The temperature regulator 11 is installed in a liquid-tight manner with the water chamber 4.

Further, the temperature regulator 11 controls the supply of electricity to the control circuit 12 of the water heater.

Next, to explain the operation, when the water chamber 4 is filled with water during normal use, the temperature controller 11
It opens and closes in response to the water temperature inside, and controls the supply of electricity to the control circuit 12.

In addition, if the water in the water chamber 4 leaks during use, or if the water in the water chamber 4 is intentionally drained to prevent freezing, etc., or if the water starts burning after forgetting to refill the water, the water in the water chamber 4 may leak. Since some of the water remains in the water reservoir 10, this water is reheated and vaporized almost instantaneously, heating the temperature regulator 11 with extremely high temperature steam, so the regulator 11 is activated immediately. The power supply to the control circuit 12 is stopped and the temperature regulator 11 is heated by extremely high temperature steam, so the regulator 11 is immediately activated and the power supply to the control circuit 12 is stopped to stop combustion.

This invention is constructed as described above, and a part of the inner wall 2 of the water chamber 4 formed by the inner and outer walls 2 and 3 is bulged toward the combustion chamber 5 to form the water reservoir 10. At the same time, a temperature regulator 11 is provided facing the water reservoir 10, so that when there is no water in the water chamber 4, the temperature regulator 11 is installed as the air in the water chamber 4 is heated. The water chamber 4
Part of the water in the water reservoir 10 is heated by leaving it in the water reservoir 10 bulging toward the combustion chamber 5, so that the water in the water reservoir 10 is instantaneously vaporized and the temperature controller 11 is turned into high-temperature steam. Since the regulator 11 is heated directly by the heat exchanger, the regulator 11 can be operated quickly, and since the structure is simple, it can be manufactured at low cost.
