Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric warming pot for keeping warm liquids such as coffee, tea, etc.
The present invention relates to a spontaneous discharge-type electric insulation pot that injects a liquid into a pot main body with a lid kept in place and pours out from a lower part of the pot main body. 2. Description of the Related Art A conventional electric insulation pot is made of metal such as stainless steel and has an inner container having a wide-open upper end and a narrow-end lower end.
A heater that heats the liquid in the inner container is provided outside the lower part of the inner container, and an outer case surrounding the inner container, a bottom member connected to a lower end of the outer case, and an upper case of the outer case are connected. An exterior body consisting of a shoulder member is provided, communicates with the lower end narrow mouth of the inner container, rises once between the inner container and the exterior body portion, and discharges the liquid in the inner container from the front lower end of the shoulder member And a lid that covers the upper end opening of the inner container at the upper end of the shoulder member, and a pneumatic bellows pump that discharges the liquid in the inner container via the discharge unit is provided in the lid. [0003] However, since the electric heat-retaining pot uses air pressure, a discharge unit must be provided between the inner container and the exterior body. The structure was complicated by the bellows pump provided in the lid. Therefore, a discharge unit communicating with the lower end narrow opening of the inner container is provided between the inner container and the bottom member, a pedestal with a receiving seat is provided at the lower end of the bottom member, and the discharge port of the discharging unit is directed toward the receiving seat of the pedestal. An electric insulation pot was developed in which the bellows pump in the lid was removed, and the liquid in the inner container was allowed to fall naturally. [0004] However, in the electric warming pot of this type, it is not possible to directly inject the electric warming pot into the inner container of the electric warming pot directly from a beverage producing apparatus for producing coffee, tea or the like. It was not possible to store the coffee, tea, etc., which had been poured out of the beverage production apparatus, in a receiver or the like, and then opened the lid of the electric insulation pot and transferred the container from the receiver to the inner container. Therefore, the operation is complicated, and this operation must be performed every time liquid is added to the electric insulation pot, which is a very troublesome operation and the upper end opening of the inner container is opened each time, so that the heat insulation effect is obtained. There was a problem that it faded. The present invention has been made in order to solve such a problem, and has a very simple structure, in which a liquid can be directly injected into an inner container while a lid is kept, and a very simple structure can be obtained. An object of the present invention is to provide an electric heating pot that can open and close an inflow passage with the inner container by an operation and has an excellent heat insulating effect when closed. [0006] An electric insulation pot according to the present invention is provided with an inner container 2 having a wide mouth at an upper end and a narrow mouth at a lower end, and a heater 10 stretched at a lower portion of the inner container.

It consists of a spring to return. One end of the unit pipe 48 of the discharge unit 8 communicates with the inside of the discharge tube 19 of the inner container via the seal pipe 51, and the other end is formed as a discharge port toward a space of a pedestal described later. Unit pipe 4 of discharge unit 8
8 may be connected to a hollow pipe communicating with a liquid amount display tube described later on the way. In this case, it is not necessary to provide an opening for the liquid amount display unit 9 of the inner container. 47 is a cover that covers the bottom of the bottom member 6 and the discharge unit 8. The liquid amount display unit 9 is disposed between the inner container 2 and the outer case 3 and includes a liquid amount display tube 52 made of a transparent glass or plastic hollow pipe and a joint member 53. . The liquid amount display tube 52 has an upper end communicating with the liquid passage of the shoulder member 4 and a lower end connected to the joint member 53.
Through the opening for the liquid level display unit 9 of the inner container. When the inside of the inner container 2 of the electric warming pot 1 is to be cleaned, or when the container from which the liquid is stored is poured at a stretch into the pot, the lid 5 can be opened. Also, when pouring directly from a beverage production device such as coffee or tea into this pot, the operation lever 29 is slid and the injection passage 24 is opened while the lid 5 is closed, so that the liquid from the beverage production device is Injection passage 24 in lid
After the injection is completed, the operation lever 29 can be slid in the opposite direction to close the injection passage 24.
