As a water heater with a conventional boil detection function,
There are hot water temperature detection methods that include a temperature sensing component at the bottom of the container, and timer methods, but both methods tend to vary in operation due to room temperature, water temperature, water volume, voltage fluctuations, etc., and cannot provide satisfactory performance. Nakatsuta. In addition, in order to eliminate these drawbacks, the first
As shown in the figure, water 2 in a container 1 is heated with a heater 3 to boil it, the steam is taken out, the thermoswitch 4 detects the steam temperature, shuts off the heater 3, and shifts to the heat retention process. There was a formal one. In this case, the heat sensitive part 5 of the thermo switch 4 is
Since it faces the side wall of the steam passage, the heat sensitive part 5 continues to be heated by the passage of hot air after boiling. Therefore, the thermoswitch 4 is not cooled properly, and recovery is delayed. For example, when cold water is added midway through, the heater circuit remains open and it takes time to bring the water back to a boil. It was hot. The present invention aims to improve this type of water heater by eliminating the above-mentioned drawbacks.

Next, to explain the operation of the above configuration, when water is poured into the container 1 and the heater 3 is energized,
The water temperature gradually rises until it reaches the boiling point and releases steam. The steam passes through the side wall of the steam passage and is discharged from the water inlet 10 to the outside. During this time, the thermally conductive flat plate 7 is heated, which heats the heat-sensitive part 5 of the thermoswitch 4 which is fixed in close contact with the flat plate 7, and the thermoswitch 4 operates to cut off the heater 3 and shift to a heat retention process. After the contacts of the thermoswitch 4 are opened, the amount of steam generated decreases, but due to residual heat, the contact does not return to normal and remains open for a while. Of course, the main body of the thermoswitch 4 is in contact with the outside air through the cover 12, such as a net, so it is cooled, but as described above, it cannot return to its original state quickly. However, in this embodiment, the water passage for injecting water also serves as a steam passage, and the heat-sensitive part 5 of the thermoswitch is in contact with the side wall 6 of the water passage, so if the thermoswitch is left open and cold water is poured, If this occurs, the heat-sensitive part is rapidly cooled by the cold water, the thermoswitch immediately closes, and the next boiling process can begin. Fourth
The figure shows another embodiment of the present invention, and although the mounting position of the thermoswitch is slightly different, its operation is exactly the same as that of FIG. 2.

As described above, the present invention is capable of providing a water heater with boil detection that quickly returns and has high responsiveness with an extremely simple configuration, and has great practical effects.
