Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrically operated jug pot that can adjust the discharge amount and perform stable pouring.

2. Description of the Related Art Conventionally, electromagnetic jars have been known in which a bellows is driven by an electromagnetic device to forcefully send air into the container, thereby automatically dispensing the solution inside the container.

Problems to be Solved by the Invention However, when the internal solution is hot water that has just been boiled, the pressure inside the container increases due to the vapor pressure of the hot water, and the amount of water discharged is greater than that of hot water that has not yet boiled. There will be more. Therefore, when using the hot water immediately after boiling, more hot water than expected is poured out, so the discharge amount by the electromagnetic device is set low in advance, and the discharge amount is constant. Therefore, even with automatic dispensing, it was not easy to use.

The present invention has solved these conventional problems, and aims to provide an electrically operated water pot that can adjust the amount of hot water discharged by simple means.

Means for Solving the Problems In order to achieve the above object, the electric jar pot of the present invention has a motor which is a drive source for dispensing the internal solution, and a heater for heating the internal solution or a heater for keeping it warm, which are connected in series. a variable resistor and a motor start switch; and a variable means for operating the motor start switch and changing the resistance value of the variable resistor, the variable resistor is configured to operate the motor according to a change in the resistance value of the variable resistor by the variable means. The applied voltage is varied.

Effect According to the above configuration, by operating the motor start switch using the variable means and changing the resistance value of the variable resistor, the voltage applied to the motor is gradually changed, and the amount of hot water discharged is adjusted according to the situation. It can be changed. Therefore, stable pouring is possible regardless of the condition of the hot water.
Since the power source for the motor is the partial pressure of the heater for heating the internal solution or the heater for keeping warm, a transformer or the like is not required, and hot water can be discharged using a small, low-voltage, and inexpensive motor.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIG. 1, reference numeral 1 denotes the exterior body of a jar pot, and a container 2 for storing hot water is provided inside. Reference numeral 3 indicates an inner stopper provided to close the mouth of the container 2, and reference numeral 4 indicates an upper lid attached to the upper part of the exterior main body 1 so as to be openable and closable. Reference numeral 5 denotes a spout, which communicates with a pumping pipe 6 inserted into the container 2 through the inside of the inner stopper 3. 7
8 is a bellows provided in the upper lid 4, and 8 is a motor which is a drive source for dispensing the solution inside the container 2, and together with the bellows 7, constitutes a pump. That is, the bellows 7 is expanded and contracted by driving the motor 8, and the intake valve 9 and the air supply valve 10 are alternately opened and closed to force air into the container 2, thereby pouring out the solution in the container 2. It is something. 11 is a solenoid, a piston ring 12 is inserted into this solenoid 11, and a diaphragm 13 is fixed to an end of this piston ring 12. The outer peripheral end of the diaphragm 13 is fixed, and expands and contracts as the piston ring 12 moves up and down to open and close a steam vent hole 14 provided in the upper lid 4.

15 is a motor start switch for starting the motor 8; 16 is a variable resistor whose resistance value is varied by operating variable means consisting of a push button 17, a switch rod 18, etc.; It is used to vary the voltage applied to the
In addition, this variable means is used when the switch rod is set to 1 at the initial stage of operation.
The motor start switch 15 is turned on via the switch 8. Reference numeral 19 denotes a compression type spring that is constantly biased to push the switch rod 18 upward, and biases the variable means itself to return to its original state.

In FIG. 2, reference numeral 20 denotes a heating heater, which is fixed to the lower side of the container 2 together with the heat-retaining heater 21. Reference numeral 22 denotes a temperature switch provided on the lower surface of the container 2, which is switched when the temperature of the internal solution reaches a predetermined temperature. 23 is a heat retention switch provided on the bottom surface of the container 2.

One end of the heating heater 20 is connected to a commercial power source B, and the other end is connected to a heat-retaining heater 21 and a temperature switch 22. A tap is provided in the middle of the heat-retaining heater 21, and the motor 8, variable resistor 16, and motor starting switch 15 are connected in series from this tap point to a commercial power source B. Further, the solenoid 11 is connected to the connection point between the motor start switch 15 and the variable resistor 16 and to the commercial power source B. Note that the intermediate tap is connected to the heat-retaining heater 2.
The heating heater 20 is not limited to 1.
It may be from.

The operation in the above configuration will be explained. When pouring, the motor start switch 15 is turned ON by operating the variable means (in this example, pressing down the push button 17).
At the same time, the solenoid 11 is activated, the piston ring 12 is lowered, and the diaphragm 13 is extended to close the steam vent hole 14. If you further operate the variable means from this state,
In order to reduce the resistance value of the variable resistor 16, the rotation speed of the motor 8 is gradually increased, and as a result, the amount of air fed into the container 2 increases and the amount of hot water discharged also increases. That is, by operating the variable means, the steam vent hole 14 can be closed and the voltage can be gradually increased, so even if the water has just been boiled, a large amount of hot water will not be suddenly discharged. .
Note that the power source for the motor 8 is the heater 2 for heating the internal solution.
Since the pressure is 0 or the partial pressure of the heat-retaining heater 21, hot water can be discharged using a small, low-voltage, and inexpensive motor without the need for a transformer or the like.

Effects of the Invention As described above, according to the present invention, when dispensing hot water, the voltage applied to the motor is gradually reduced by operating the motor start switch using the variable means and changing the resistance value of the variable resistor. change,
The amount of hot water discharged can be changed depending on the situation. Therefore, regardless of the state of the hot water (whether it has just boiled or not), hot water can be stably discharged without the risk of burns, making it easy to use. Since the motor's power source is the partial pressure of the heater for heating the internal solution or the heater for keeping it warm, there is no need for a transformer, and the motor is compact, low-voltage, and inexpensive, making it extremely excellent as a jar pot.
