Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a jar pot used in general households and the like.

Conventional technology In conventional jar pots, hot water is pushed out by pushing the air pump built into the lid manually, by driving the air pump with a solenoid coil to increase the air pressure inside the container, or by using an electric motor powered by dry batteries. The system was designed to drive a pump to draw hot water from the container.

Problems to be Solved by the Invention However, with these configurations, the discharge amount cannot be adjusted, and when hot water is supplied to a large container,
In the past, it was inconvenient because the time required to supply hot water was long, and when supplying hot water to a small container, the amount of discharged water was so large that the hot water could splash nearby and cause burns, which was dangerous.

The present invention has been made in consideration of the above-mentioned conventional problems, and an object of the present invention is to provide a jar pot whose discharge amount can be freely changed.

Means for Solving the Problems In order to solve the above problems, the jar pot of the present invention includes a pump that discharges liquid in a container to the outside of the container, an electric motor that drives this pump, and a direct current that is supplied to this electric motor. The device has a variable output DC power supply means and a switch for connecting the second heater to either the input of the variable output DC power supply means or the energization control means.

Effect With this configuration, when discharging the liquid in the container, by switching the switch and connecting the second heater to the input of the variable output DC power supply means, the AC power source - the variable output DC power source means - the switch is switched. - An energizing path for the second heater AC power supply is formed, and DC is supplied from the variable output DC power supply means to the electric motor, the electric motor rotates, the pump is driven, and liquid is discharged from the container.

The discharge amount is changed by changing the output of the variable output DC power supply means, thereby changing the rotational speed of the electric motor.

When not discharging the liquid in the container, the switch connects the second heater to the energization control means, and forms an energization path of AC power source - energization control means - switch - second heater - AC power source, If the temperature of the liquid in the container is less than the set temperature of the energization control means, the energization control means becomes conductive and energizes the second heater, and when the temperature of the liquid in the container exceeds the set temperature of the energization control means, the energization control means is turned off. A so-called heat-retaining operation is performed in which the second heater is conductive and is not energized.

Embodiment An embodiment of the present invention will be described below based on the drawings. In FIG. 1, 15 is an AC power source, and this power source 15 is connected to a first heater 1 and a second heater for keeping warm.
heaters 2 are each independently connected.
A thermostat 7 with hysteresis characteristics (on at 88°C, off at 96°C) is inserted into the energizing circuit of the first heater 1, and a thermostat 7 that controls the temperature of the water in the container is inserted into the energizing circuit of the second heater 2. An energization control means 5 and a switch 6 are provided, which become conductive when the temperature drops below a set temperature (92°C), and the switch 6 switches between the energization control means 5 of the heater 2 and the input of the variable output DC power supply means 4. It's starting to connect. The output variable means 4 includes a triax 401 and a capacitor 40.
2,403, diac 404, variable resistor 40
5, a bridge diode 406, and a smoothing electrolytic capacitor 407, and is configured to supply power to the electric motor 3 that drives the pump.

FIG. 2 shows a jar pot incorporating the above circuit device, in which 11 is a container, 12 is a pump, and 1
3 is a water pipe, 14 is a hot water discharge port, and when the electric motor 3 drives the pump 12, the hot water in the container 11 is discharged from the pump 1.
The liquid is discharged from the discharge port 14 through the water pipe 13.

The operation in this configuration will be explained.

When discharging hot water, the switch 6 is switched to the variable output DC power supply means 4 side, forming a circuit of AC power supply 15 - variable output DC power supply means 4 - switch 6 - second heater 2 - AC power supply 15. .

Then, the capacitor 403 becomes the variable resistor 405
When the potential difference with the gate of the triac 401 exceeds the breakover voltage of the diode 404, the diode 404 is turned on, the triac 401 becomes conductive, and the bridge diode 406 is energized.
The current rectified by 06 is passed to the smoothing electrolytic capacitor 4.
07, it becomes a direct current and is supplied to the electric motor 3, which rotates and drives the pump 12.
Hot water pushed out by the pump 12 passes through the water pipe 13 and is discharged from the discharge port 14.

The amount of hot water discharged can be determined by changing the resistance value of the variable resistor 405 of the variable output DC power supply means 4, thereby changing the charging curve of the capacitor 403 and changing the timing at which the dial 404 is turned on. This is done by changing the conduction angle, changing the amount of current supplied to the electric motor 3, and changing the rotational speed of the electric motor 3.

When hot water is not to be discharged, the switch 6 is switched to the energization control means 5 side.

Then, a circuit consisting of AC power supply 15 - energization control means 5 - switch 6 - second heater 2 - AC power supply 15 is formed, and the energization control means 5 controls when the temperature of the hot water in the melter falls below the set temperature (92°C). When the temperature reaches the set temperature, it becomes conductive and becomes non-conductive when the temperature exceeds the set temperature, thereby performing a heat-retaining operation.

The thermostat 7 controls the energization of the first heater 1 by turning on at 88° C. or lower and turning off at 96° C. or higher, thereby performing a so-called water boiling operation.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, the discharge amount can be freely changed, and it is safe and easy to use. By using it as a series resistor, it is possible to provide an inexpensive, small and lightweight jar pot.
