DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water storage container such as an electric pot used at home and the like, and more particularly to a hot water storage container capable of cooling heated hot water.

[0002]

2. Description of the Related Art A conventional hot water storage container is for heating a content liquid, storing the heated content liquid at a high temperature, and supplying a high temperature content liquid.

[0003]

However, drinks made at home or the like are not limited to those using hot water such as tea, but also those using cold water or powdered milk for infants. Some use appropriate hot water.

[0004] The conventional hot water storage container is convenient when high-temperature hot water is used, but cannot be used for supplying cold water, and it is necessary to mix water when using appropriate-temperature hot water. In addition to inconvenience, there is a problem that it is not sanitary to mix water when dissolving infant milk.

The present invention solves the above-mentioned problems, and not only heats and heats the content liquid to store hot water, but also cools the heated content liquid to store low-temperature water, and removes hot water and cold water. It is an object of the present invention to provide a hot water storage container that can selectively discharge and supply hot water or cold water individually from the outside.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, a hot water storage container according to the present invention has, in a single case, a water heater for heating and boiling a liquid content, and heating in the water heater. In a hot water storage container provided with a cooling unit for supplying and cooling the content liquid, a water container with an opening / closing lid for keeping and storing the content liquid heated in the water heater unit, and cold water cooled in the cooling unit. A cooling tank with an opening / closing lid for cooling and storing water, and a selective discharge means for selecting the hot water stored in the water heater container and the cold water cooled and stored in the cooling tank and discharging the same to the outside, in the one case. It is characterized by having been provided.

[0007]

In the hot water storage container of the present invention, the water heater heats the content liquid, and the water heater heats and stores the heated content liquid in the water heater with the opening / closing lid. Since the hot water stored in the water heater container and the cold water cooled and stored in the cooling tank with the opening / closing lid are selected and discharged to the outside, high-temperature hot water or cold water can be selectively used.

In the hot water storage container of the present invention, since both the water heater container and the cooling tank are provided with an opening / closing lid, hot water supply and water supply to the water heater container and the cooling tank can be individually performed from outside, and Easy to clean the kettle and cooling tank.
