Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric pouring type hot water storage container for pouring liquid contained in an inner container to the outside through an electric pump.

[0002]

2. Description of the Related Art In an electric pouring type hot water storage container, it is possible to selectively use hot water in a large-capacity vessel (for example, a pot) and hot water in a small-capacity vessel (for example, a coffee cup). In addition, by controlling the electric power to the electric pump according to the operating force of the user with respect to the switch, it has been proposed that the discharge amount of the electric pump (in other words, the hot water supply amount) can be adjusted (for example, , Tokuhei 4-2208
No. 9).

[0003]

However, in the case of the electric pouring type hot water storage container represented by the above-mentioned known example, the discharge amount of the electric pump is adjusted according to the operating force of the user with respect to the same switch operating portion. Therefore, the discharge amount increases or decreases depending on the subtle force.
Therefore, when hot water is supplied with a large discharge amount contrary to the user's intention, hot water may be scattered around.

Under the circumstances as described above, there has been an increasing demand in recent years for the switch operating section to be independent for obtaining a large amount of hot water and a small amount of hot water.

The present invention has been made in view of the above points, and it is an object of the present invention to surely obtain a large hot water supply amount or a small hot water supply amount by operating separate switch operating portions. Is.

[0006]
