Conventional electric pots of this type heat the water in the pot using a heating element with a large heating capacity, e.g.
℃, and then heated using a heat-retaining heating element with a small heat generating capacity to maintain the temperature slightly higher than 95℃, which caused the problem that the water could not be used once it had been boiled. By the way, it is said that tea and coffee taste better when boiled water is used, and a pot that satisfies these demands has been desired.

This idea uses a heating element with a large heat generating capacity to heat the water in the pot until it reaches a temperature close to the boiling point, and after reaching that temperature, controls the energization of the heating element with a small heat generating capacity. In a heat-retaining device, by setting a timer, after the water in the pot reaches the above temperature, a heating element is operated for a further set time to boil the water.

Figure 1 is a circuit diagram showing an embodiment of this invention.
AC power supply 1, power switch 2 and temperature fuse 3
are connected in series to a series circuit consisting of a heat-retaining heating element 4 with a small heat generating capacity, for example, about 50W, a temperature-sensitive reed switch 5 as a second temperature-sensitive switch, a relay 6, and a thermoswitch as the first temperature-sensitive switch. 7 and a series circuit between the normally open contact 61 of the relay 6 and a heating element 8 having a large heat generating capacity, for example, about 620 W, are connected to each other. The thermo switch 7 detects the water temperature inside the pot.
It operates ON and OFF, for example, when the water temperature in the pot reaches the first set temperature of 95℃ or higher.
It operates OFF and turns ON when the temperature drops below 90°C, which is the second set temperature. The temperature-sensitive reed switch 5 detects the water temperature in the pot and turns on.
For example, when the water temperature is slightly higher than 95 degrees Celsius, or 97 degrees Celsius or higher, it turns OFF, and when the temperature drops below that temperature, it turns ON.
A water boiling indicator circuit 11 formed by connecting a lamp 9 and a resistor 10 in series is connected to the relay 6 in parallel. The relay 6 is connected to the normally open contact 61 of the relay 6.
A series circuit of the first normally closed contact 62 and the timer contact 12 is connected in parallel. The timer contact 12
A warming indicator circuit 15, which is formed by connecting a resistor 13 and a lamp 14 in series, is connected in parallel. A timer 16 is connected in parallel to the series circuit of the relay 6 and thermoswitch 7 through the first normally closed contact 62 of the relay 6, the timer contact 12, and the second normally closed contact 63 of the relay 6 in series. are doing. The timer 16 is, for example, of a manual setting type, and the timer contact 12 is turned on by manually setting the time.
However, when the set time elapses after being energized, the timer contact 12 is turned off. Said timer 1
6 is connected in parallel with a boiling indicator circuit 19 formed by connecting a lamp 17 and a resistor 18 in series.

熱体4が水温97℃近傍に略一定に保持される。 In the embodiment of the present invention having such a configuration, if the power switch 2 is turned on without setting the timer, the relay 6
is energized, and electricity starts to be applied to the heating element 8 for heating via the normally open contact 61, and at the same time, electricity to the heating element 4 for keeping warm is started via the temperature-sensitive reed switch 5, and the water in the pot is heated. be done. At this time, the lamp 9 lights up to indicate that the water is being boiled. When the water temperature reaches 95℃, thermo switch 7 will turn on.
OFF, and relay 6 is deenergized. This turns off the normally open contact 61 and stops the heating element 8 from generating heat. In addition, the lamp 9 goes out, and the first normally closed contact 62 of the relay 6 and the heating element 8 are turned off.
The lamp 14 lights up through the circuit to indicate that the temperature is being kept warm. At this time, the current flowing through the heating element 8 is extremely small because the resistance value of the resistor 13 is large, and the heating element 8 does not generate heat. Thereafter, the temperature-retaining heating element 4 is controlled by the temperature-sensitive reed switch 5 to maintain the water temperature approximately constant at 97°C.

作が行われる。 Also, if the timer 16 is set in advance, the timer contact 12 is turned ON, so when the water temperature reaches 95°C, the thermo switch 7 is turned OFF, and the first relay 6
When the second normally closed contacts 62 and 63 are turned on, energization to the timer 16 is started and energization to the heating element 8 continues, and thereafter the water temperature reaches the boiling point. In this way, the water in the pot is boiled. At this time, the lamp 17 lights up to indicate that the boiling operation is in progress. After that, when the set time has elapsed and the timer contact 12 turns OFF, the lamp 1
7 goes out, the lamp 14 lights up, and the above-mentioned heat retention operation is performed.

ト内の水は直ちに沸騰される。 Also, even if the timer 16 is not set in advance, if the timer 16 is set while keeping warm, the timer contact 12 will be activated.
The power is turned ON, and the power supply to the heating element 8 is restarted, and the water in the pot is immediately boiled.
さらに保温中にポツト内に水を追加して水温が
90℃以下になるとサーモスイツチ7がONし、加
熱用発熱体8により直ちに95℃以上加熱される。 Furthermore, water is added to the pot while it is being kept warm to raise the water temperature.
When the temperature drops below 90°C, the thermo switch 7 is turned on, and the heating element 8 immediately heats the temperature above 95°C.

ツトの状態を常に正しく知ることができる。 By setting the timer 16 in this way, the water in the pot can be brought to a boil. Furthermore, since the setting time of the timer 16 can be arbitrarily set manually, the setting time can be determined according to the amount of water in the pot, making it possible to ensure boiling and boiling for an appropriate period of time. I can do it. Furthermore, since the lamps 9, 14, and 17 can indicate whether the water is boiling, keeping warm, or boiling, the status of the pot can always be accurately known.

以下説明する。なお前記実施例と同一部分には同
一符号を付して詳細な説明は省略する。 FIG. 2 is a circuit diagram showing another embodiment of this invention, which will be explained below. Note that the same parts as in the above embodiment are given the same reference numerals and detailed explanations will be omitted.
これは保温用発熱体4と感温リードスイツチ5
の直列回路に換えて保温用発熱体20と感温リー
ドスイツチ21の直列回路をリレー6の常開接点
61に並列に接続したものである。 This is a heat-retaining heating element 4 and a temperature-sensitive reed switch 5.
In place of the series circuit, a series circuit of a heating element 20 for heat retention and a temperature-sensitive reed switch 21 is connected in parallel to the normally open contact 61 of the relay 6.

く発熱する虞れはない。 In this case, thermo switch 7 is OFF.
Until this happens, the series circuit of the heating element 20 and the switch 21 is short-circuited by the normally open contact 61 of the relay 6, so the heat-retaining heating element 20 is not operated at all during that time. When the thermo switch 7 is turned off, the temperature-sensitive reed switch 21, the heating element 20 for heat retention, and the heating element 8 for heating are activated.
An energizing path is formed through the . At this time, since the resistance value of the heating element 20 for heat retention is considerably larger than the resistance value of the heating element 8 for heating, most of the power supply voltage is applied to the heating element 20 for heat retention, and there is a possibility that the heating element 8 for heating will generate a large amount of heat. There isn't.
