The microcomputer mounted in 8 starts boiling detection.

The microcomputer mounted in the control device 28
When it is determined to be boiling, the main heating element is stopped, and the temperature is maintained by the auxiliary heating element to be in a heat retaining state.

Here, when the light saving selection key 27 is pressed (turned on), the light sensor 26 operates, and the light sensor 26 detects the amount of external light and sets the amount of external visible light. It is to determine whether or not the light amount is higher than the determined light amount.

When the amount of external visible light is detected to be equal to or less than a predetermined amount, the controller 28 keeps the hot water at a second temperature, for example, 60 ° C., which is lower than a predetermined normal temperature. In addition, when the light amount is equal to or more than a predetermined light amount and the hot water temperature is, for example, 90 ° C. or less, the heating element 4 is energized to perform water boiling, and thereafter, a predetermined temperature, for example, 96 ° C. is maintained. Therefore, the unused power during the operation of the optical sensor in FIG. 2 has an energy saving effect.

Further, by providing a fixed time for detecting the amount of external visible light, the light sensor can detect the presence of a person who is active in the daytime or an object at a moment, turn on the light for a moment at night, or There is no need to detect the light of a passing car or the like, and there is no needless operation or water heating.

Also, by changing the time for detecting the light amount equal to or less than the certain light amount and the time for detecting the light amount equal to or more than the certain light amount, for example, the time for detecting the light amount equal to or less than the certain light amount is set to several seconds. Without doing,
When you turn off the lights to go to bed at night, you can confirm in a few seconds that the light sensor detects.

On the other hand, by setting the time for detecting a certain amount of light or more to, for example, several minutes, the light sensor can detect light for a short time such as going to a toilet at night or drinking water when the throat dries. In addition, there is no need to heat the water when it is not necessary, and no needless electricity is consumed.

Next, when the power saving selection key 27 is turned off, the main body 1 is used in a dark place such as a corner of a room or on a shelf, or when there is no ordinary person such as a tea room in a company. If the camera is used in a dark room with the lights turned off, or when it is still dark or when it wakes up in the middle of the night, a predetermined temperature (approximately 96
C), so that hot water at a predetermined temperature can be used immediately.

[0025]

As is apparent from the above description, the jar pot of the present invention maintains the second warming temperature (60 ° C.) when the external light amount is equal to or less than the predetermined light amount, so that the jar pot can be used at night. It can save electricity when people are not very active, such as when the room is dark.

Further, since the temperature is maintained at 60 ° C., the water can be heated in a short time, for example, when it becomes bright in the morning or when hot water is required at night. Further, even if the temperature is kept at 60 ° C. for a long time, the temperature at 60 ° C. makes it difficult for bacteria and the like to propagate in hot water.

Further, when used in a dark place such as in a corner of a room or on a shelf, or when used in a dark room where there is usually no person and the light is turned off, such as a company tea room, a light power saving selection key is used. If is turned off, the temperature can be kept at a predetermined temperature (about 96 ° C.) at any time.
