Description

[Detailed Description of the Invention] <Industrial application field> The present invention is an electric appliance suitable mainly for formulating infant powdered milk, which is capable of boiling water for drinking on the one hand and disinfecting hot water such as a container on the other hand. Regarding water heater.

<Prior Art> Conventionally, when formulating a powdered milk, a baby bottle was first immersed in hot water for a certain period of time to be sterilized, and hot water for formulating milk was boiled using a separate container.

<Problems to be Solved by the Invention> In the above-mentioned conventional method, there is a risk of burns when hot-disinfecting a baby bottle, and it is necessary to use a separate container to boil hot water for milk preparation. However, it is troublesome and troublesome.

<Means for Solving the Problems> The present invention solves the above-mentioned conventional problems by separating the heating tank into two and connecting the respective heating tanks to the cleaning tank and the heat-retaining tank through a communication pipe. Settled.

<Function> The hot water in the heating tank heated by the heater is pushed up to the cleaning tank and the heat-retaining tank by the siphon principle, and is separately provided for hot water disinfection and drinking.

<Embodiment> Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

FIG. 1 is a simplified cross-sectional view, in which reference numeral 1 indicates a funnel-shaped cleaning tank having a small-diameter water conduit 1 ′ on the lower side, and the lower end opening of the water conduit 1 ′ is a container 4 for heating tank. Face the bottom,
Airtight packing 2 is placed on the container 4 inside the heating tank and the container 3 outside the heating tank.
Is attached through. In addition, the above-mentioned heating tank outer container 3
Is provided with a water conduit 7 communicating with the heat-retaining tank 6 with its lower end opening facing the bottom surface. A two-way valve 9 is provided in the middle of the water pipe 7 to shut off the communication with the heat-retaining tank 6 and to connect the heat-retaining tank 6 to the hot water supply port 8 opened to the outside.

Reference numeral 5 is a heating heater, 10 is a heat retaining heater for keeping the temperature of the hot water in the heat retaining tank 6 constant, 11 is a cooling fan, 12 is a filter for washing water, and 13 is a container such as a baby bottle to be washed. .

Next, the operation of the electric water heater of the present invention having the above configuration will be described. First, after putting water for cleaning in the heating tank container 4, the cleaning tank 1 is airtightly attached to the upper portion thereof, and then,
The cleaning tank 1 is airtightly mounted on the heating tank outer container 3 containing drinking water as described above, and the container 13 such as a baby bottle to be cleaned is put in the cleaning tank 1 to complete the preparation. In this state, when the heater 5 is energized to heat the water in the heating tank inner / outer containers 3 and 4, first, the hot water in the heating tank inner container 4 has a higher pressure in the heating tank inner container 4. As a result, the siphon principle pushes the water from the water conduit 1'into the washing tank 1, and the container 13 such as a baby bottle previously put in the washing tank 1 is sterilized by boiling. At the same time, the water in the heating tank outer container 3 is also heated and the pressure is increased, so that the water is pushed up into the heat insulating tank 6 from the water conduit 7. Next, when the energization of the heater 5 is stopped, the temperature inside the container 4 inside the heating tank is lowered due to the temperature drop, and the warm water pushed up into the cleaning tank 1 returns to the container 4 inside the heating tank.
Cleaning of the container 13 is completed. At the same time, at this time, the pressure in the container 3 outside the heating tank is also lowered, and the warm water in the heat insulating tank 6 tries to return, but the return is blocked by switching the two-way valve 9. The warm water stored in the tank 6 is kept at an appropriate temperature according to the application, for example, at 50 ° C. to 55 ° C. when preparing powdered milk, by the heat retention heater 10 and the cooling fan 11.

In this embodiment, the container in the heating tank is stored in the container outside the heating tank after being attached to the cleaning tank, but it is sufficient if the heating tank is divided into two tanks. The container in the heating tank may be integrally provided, and the cleaning tank may be attached to the upper part of both.

Further, in the above-mentioned embodiment, the case of using it for preparing milk was mainly explained, but it goes without saying that it may be used for other purposes such as coffee.

<Effect of device> As described above, the electric water heater of the present invention can boil the hot water used for drinking and at the same time sterilize the container by boiling. It also has excellent thermal efficiency because both operations are performed with one heater. Even when warm water (hot water) at a relatively low temperature is needed, such as when formulating powdered milk, the hot water supplied in a boiling state to the heat-retaining tank can be used in a short time with a cooling fan to suit the application. It can be adjusted to any temperature.
Furthermore, since boiling water for boiling disinfection moves up and down the washing tank on the basis of the siphon principle, containers such as baby bottles can be put in and taken out without directly touching the hot water, and there are many excellent effects that there is no danger of burns and safety is excellent. Play.
