Description

[Detailed Description of the Invention] The present invention relates to a hot water maker that heats liquid and stores it at high temperature.

Traditionally, thermos flasks have been provided to store boiling water at high temperatures, but since the hot water needs to be poured from the outside, there is a risk of getting burned when pouring it, and when a certain amount is used, It was necessary to make hot water using a heating device and inject the hot water through an inlet/outlet at the top, making it difficult to handle.

The present invention was developed in view of the above circumstances, and includes a structure in which an insulated container, a liquid tank, and a heating device are provided in the outer casing, and the liquid in the liquid tank is heated by the heating device and then supplied to the insulated container. To provide a boiling water maker which is extremely easy to handle, with no risk of burns, etc., since it is only necessary to supply low-temperature liquid to the liquid tank, and replenishment after a certain amount has been used is extremely simple. It is in.

A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

1 is an outer casing with open top and bottom surfaces, and a liquid tank 2 is located on the upper left side of this.
A dry cell storage section 3 is integrally provided on the right side of the liquid tank 2.

Reference numeral 4 denotes a heat insulating container made of, for example, glass, disposed below the dry cell storage section 3, which has a double wall structure with a vacuum layer formed in the middle, and is fixed to the partition plate 5 and the bottom plate 6. It is supported on a support member 7.

A plug member 8 is fitted into the opening of the heat insulating container 4, and a discharge pipe portion 8a projecting to the outside of the outer casing 1 is integrally formed with this plug member.

Reference numeral 9 denotes a suction pipe whose upper end is fitted into the discharge pipe part 8a of the plug member 8, and whose lower end is located at the inner bottom of the heat insulating container 4.

Reference numeral 10 denotes a pump attached to the lower end of the suction pipe 9, and its drive shaft 11 is directly connected to a motor 12 located in the dry cell storage section 3.

Reference numeral 13 represents a dry cell battery that serves as a power source for this motor 12, and reference numeral 14 represents a switch that controls power supply/disconnection of the motor 12.

Reference numeral 15 denotes a heating device disposed on the bottom plate 6, in which a substantially U-shaped sheathed heater 16 and a heating pipe 17 are supported in a supporter 18 in a substantially intimate state. A switch 19 is provided.

Reference numeral 20 denotes an inflow section extending upward from one end of the heating pipe 17, to which an outflow pipe 22 as a connecting pipe extending to the liquid tank 2 is connected via a check valve 21. .

Reference numeral 23 denotes an outflow section extending upward from the other end of the heating pipe 17, to which one end of a hot water supply pipe 25 serving as a connecting pipe is connected via a check valve 24.

The other end of the hot water pipe 25 is inserted into the heat insulating container 4 through a hole 8b provided in the plug member 8.

Note that 26 is a lid that opens and closes the top surface of the liquid tank 2.

Next, the operation of this embodiment configured as above will be explained.

When water is poured into the liquid tank 2 and electricity is supplied to the sheathed heater 16 by connecting a plug (not shown) to a power source, the outflow pipe 2
2 and the heating pipe 1 from the inlet 20 via the check valve 21.
Water from the liquid tank 2 is supplied into the tank 7.

When this water is heated and boiled in the heating device 15 by the sheathed heater 16, its volume expands and flows out into the hot water pipe 25 via the check valve 24, and the hot water is stored in the heat insulating container 4.

When all of the water in the liquid tank 2 is boiled and stored in the heat insulating container 4, the power to the sheathed heater 16 is cut off.

Now, when taking out hot water from the insulated container 4, switch 1.
4 is closed and the motor 12 is energized to drive the pump 10, hot water flows out through the suction pipe 9 and the discharge pipe portion 8a.

Also, when the hot water in the heat insulating container 4 decreases by a predetermined amount, water is poured into the liquid tank 2 and the sheathed heater 16 is energized in the same manner as described above.
stored within.

Note that if the pump 10 is driven even during the generation of hot water in this way, it is possible to take out the hot water from the heat insulating container 4.

In this way, according to this embodiment, the heating device 15 is provided inside the outer casing 1.
Since the liquid tank 2 only needs to be replenished with water, there is no need to replenish high-temperature boiling water like in conventional thermos flasks, so there is no risk of burns and replenishment after a certain amount has been used. It is also very easy to handle, since it is sufficient to simply put low-temperature water into the liquid tank 2, and there is no need to heat it with a separate heating device to make hot water.

FIG. 3 shows a second embodiment of the present invention, and shows the first embodiment.
To explain the different parts from the diagram, it has a configuration in which a dry cell storage section 3 is provided directly above the heat insulating container 4, a liquid tank 2 is provided above it, and a heating device 15 is provided directly below the heat insulating container 4. The same effects as in the first embodiment are achieved.

As is clear from the above explanation, the present invention eliminates the risk of burns, etc., since it is sufficient to supply low-temperature liquid to the liquid tank.
To provide a hot water maker which is extremely easy to handle and can be refilled after a certain amount has been used.
