DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing hot water by heating a content liquid by a heater at the bottom, a lead-out path for guiding the content liquid inside the container to the outside of the container, and a liquid content inside the container through the lead-out path. And a power supply circuit for supplying power to electric devices such as a heater and an electric pump, which are used, for example, as household electric pots.

[0002]

2. Description of the Related Art Such electric hot water storage containers are widely used as electric pots in general homes and workplaces. Electric pots are now used while connected to a household power source all the time except when refilling or replacing the contents, and can be used by discharging the contents during warming at any time.
When a boiling content solution is desired, the content solution being kept warm can be boiled in a short time by a re-boiling operation. Further, for convenience of use, those which discharge the content liquid by an electric pump are often used.

[0003]

Incidentally, there are occasions when it is desired to carry an electric pot to a place where a household power supply is not provided, such as at home or work, and use it. In this case, the electric pot for electric dispensing cannot be used in a place where there is no power supply. Further, since the content liquid cannot be heated without a power source, the content liquid is only being cooled, and is cooled early in winter or in a cold region, so that it cannot be used in a short time.

Therefore, it is conceivable to use a secondary battery as a power source for the electric pot. However, since the electric pot has a high load state such as energization of the heater, it is quickly consumed, the interval of charging becomes too short, and the life of the secondary battery is shortened.

It is also conceivable that the electric pot has a power supply circuit that can use both an AC power supply and a secondary battery charged by the AC power supply.

However, when the secondary battery is installed using the bottom space of the container, the life is shortened due to the influence of heat from the heater. Further, even if the secondary battery is charged when the AC power supply is used, the service life will be reached if the charging is repeated a predetermined number of times or more. Therefore, a structure that can be replaced is required, and the installation position and the installation structure need to be devised.

An object of the present invention is to provide an electric hot water storage container that can use a secondary battery without any problem.

[0008]

Means for Solving the Problems To achieve the above object, an electric hot water storage container according to the first aspect of the present invention comprises:
A container for storing the hot water by heating the content liquid with a heater at the bottom,
It has an electric pump that discharges the liquid inside the container through the lead-out path and a secondary battery that is charged by an AC power supply.When there is no AC power supply connected, the secondary battery works as a power supply and supplies power to the electric pump. And a charging control unit that charges the secondary battery only when the power supply load is small in a power supply state from the AC power supply. The invention according to claim 2 is characterized in that it further comprises a secondary battery disconnecting means for disconnecting the secondary battery connection electrode from the power supply circuit when the secondary battery is not mounted.

In such a configuration, when the AC power supply is connected, the power supply circuit stores the liquid content by operating the electric device such as the heater as usual by the power supply from the AC power supply while charging the secondary battery. At any time, it is possible to stand by so that the heat retention contents liquid or the boiling contents liquid is discharged and used by the electric pump at any time, and when the AC power supply is not connected, the power supply circuit operates during the power supply from the AC power supply. Since the electric pump is supplied with power from the charged secondary battery, the electric pumping function of the contents liquid by this electric pump can be demonstrated even in places without AC power supply, so that the contents liquid cannot be poured. Can be prevented. In particular, when the power supply load is small when the power supply circuit is in the power supply state from the AC power supply, the secondary battery is charged by the charging control means. It is possible to avoid such a problem that the functioning of the electrical equipment that is functioning due to the power supply becomes weak, malfunctions or inoperability of the electrical equipment.

According to a second aspect of the present invention, there is provided a container body for heating and storing hot water by heating a content liquid by a heater at the bottom, an electric pump for discharging the liquid content inside the body to the outside of the body through an outlet path, and an AC power supply. A power supply circuit that serves as a power source when the secondary battery is charged by the secondary battery and there is no AC power supply connected to the electric pump, and when the secondary battery is not mounted, A secondary battery disconnecting means for disconnecting the connection electrode from the power supply circuit is provided.

In such a configuration, when the AC power supply is connected, the power supply circuit stores the liquid content by operating the electric device such as the heater as usual by the power supply from the AC power supply while charging the secondary battery. At any time, it is possible to stand by so that the heat retention contents liquid or the boiling contents liquid is discharged and used by the electric pump at any time, and when the AC power supply is not connected, the power supply circuit operates during the power supply from the AC power supply. Since the electric pump is supplied with power from the charged secondary battery, the electric pumping function of the contents liquid by this electric pump can be demonstrated even in places without AC power supply, so that the contents liquid cannot be poured. Can be prevented. In particular, if a secondary battery is not installed, it is easy for a human hand to touch the connection electrode with the secondary battery and cause leakage to the human body. Since the disconnection means disconnects the secondary battery connection electrode from the power supply circuit so that no current flows from the power supply circuit, the problem of the electric leakage is solved.

According to a third aspect of the present invention, in the electric hot water storage container according to any one of the first and second aspects, the secondary battery is further housed in a battery box, and the battery box can be attached to and detached from a battery chamber of a body. It is connected to the electrode of the battery chamber by being mounted as described above, detects the presence or absence of the battery box in the battery chamber, and if mounted, connects the electrode to the power supply circuit,
There is a circuit that does not connect to the power supply circuit if it is not installed, so if the electrode is external and the electrode is exposed and touched externally without the secondary battery attached, electric leakage will occur Such a problem is solved.

As shown in FIG. 6, the control circuit 19 includes a power supply circuit 5 using a household AC power supply 51 and a secondary battery 55 in combination.
3, while the AC power supply 51 is connected, and when the power load is small, the secondary battery 55 is charged and the power is supplied from the AC power supply while the AC power supply 51 is not connected. 55 is supplied. In addition, while power is being supplied from the secondary battery 55, the power supply to the heater 3 is stopped to suppress power consumption, and when the temperature of the content liquid drops to a low temperature range where use is not endurable, the discharge of the content liquid is restricted. In this case, it is easy to cope with this, and the wasteful discharge of the content liquid is prevented.

The secondary battery 55 is removably mounted in a battery chamber 301 formed by using a projection 8b provided with a bearing 32 of the shoulder member 8 as shown in FIGS. 1, 3, and 4. It is. The battery chamber 301 can be formed only by the protruding portion 8b.

The electric pump 14 is a DC electric pump,
Together with the microcomputer 56, a DC circuit is formed. As shown in FIG. 6, the power supply circuit 53 of the control circuit 19 has an AC circuit section for supplying the AC from the AC power supply 51 to the warming heater 3a, the boiling heater 3b, and the DC power supply circuit 57 in which the heater 3 is separately provided. are doing. The DC power supply circuit 57 converts the AC from the AC power supply 51 to a predetermined DC voltage via the transformer 54 and supplies power to the DC circuit unit.
While the AC power supply 51 is connected and the control circuit 19 is in a state of a small power load, the secondary battery 55 is charged through the charging circuit 58 while the power from the AC power supply 51 to the warming heater 3a and the boiling heater 3b is supplied. When the power load of power supply is large, the power supply is performed without charging the secondary battery 55.

Power is supplied from the DC power supply circuit 51 of the first embodiment to the pump circuit 59 through the booster circuit 60.
Although the necessary voltage is ensured, it is also possible to generate a required type of DC voltage by the DC power supply circuit 57 and supply it to the pump circuit 59 directly.

Whether or not the AC power supply 51 is connected is determined by a signal from a reset circuit 162 connected between the AC circuit section and the microcomputer 56, and whether the AC power supply 51 is connected or not is determined. The above control difference is automatically switched. The heating heater 3a is energized under control of the microcomputer 56 through the triac 61 so as to achieve the setting mode and the heating mode according to the program, and the boiling heater 3b is controlled by the microcomputer 5 through the relay 62.
Under the control of 6, the energization control is performed so as to achieve water heating in accordance with the setting mode and its program.

In the first embodiment, the boiling heater 3
By utilizing the low capacity of b and supplying power from the secondary battery 55 through the booster circuit 60, the DC power supply circuit 57
Thus, power can be supplied to the boiling heater 3b through a relay 62 controlled by a microcomputer 56. Specifically, from the relation of the equation W = V ² / R, for example, the heat retention heater 3a
w = 100V ² / 150Ω and a resistance value of about 150Ω to obtain a heat generation capacity of about 66W, and the boiling heater 3b
Is also 100W AC power, 1000W = 10
The resistance value is about 10Ω in order to obtain 0v ² / 10Ω and a heat generation capacity of about 1000W. Therefore, the secondary battery 5
Even if the voltage from the power supply 5 is boosted by the booster circuit 60 or the like, the voltage is currently as low as about 10 V, and the low voltage secondary battery 55 supplies power to the low-capacity boiling heater 3b. The heat generating capacity is 10w = 10V ² / 10Ω, and the heat can be kept with low power consumption.

When the temperature is maintained by the power supply from the secondary battery 55, even if the heating is not sufficient, the temperature drop rate of the content liquid is greatly delayed, and the time required for the content liquid to reach the low temperature region where the discharge is incompatible is lengthened. Thus, the service life without the AC power supply 51 can be extended. If the voltage guarantee values of the secondary battery 55 and the booster circuit 60 increase, sufficient heat retention can be achieved.

When the hot water supply key 70 is operated, the control circuit 19 activates the electric pump 14 by operating the pump circuit 59 via the relay 63 by the microcomputer 56 to discharge the liquid content.

The microcomputer 56 includes, for various necessary controls, the operation board 20 of the operation panel 122, the projection of the water amount detection means 173, the light receivers 173a and 173b, and the LE.
D-lamps 22a to 22f and an LED lamp 22g for indicating the necessity of water absorption when the amount of unsuitable discharge water is mounted or connected, as shown in FIG.
73c. The microcomputer 56 also receives a signal from the temperature sensor 4 and performs a boiling control and a heat retention control based on the signal, and operates a buzzer 64 connected to the output side in a timely manner to issue various warnings. Also, the progress and status of various operations are notified by sound along with the lamp display. It should be noted that a warning or display using pseudo sound can be performed instead of the buzzer.
