Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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 body with the lid kept on, and discharges the liquid from a lower portion of the pot body.

[0002]

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 for heating the liquid in the inner container is provided outside the lower portion 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 connected to an upper end of the outer case. An exterior body consisting of a shoulder member is provided, communicates with the narrow end of the inner container, rises once between the inner container and the exterior body, 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 pot uses air pressure, a discharge unit must be provided between the inner container and the exterior body, and it is installed in a narrow gap, so that the assembling work is troublesome. 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 inside 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 inject directly into the inner container of the electric warming pot from a beverage producing apparatus for producing coffee, tea or the like. After temporarily storing coffee, tea, and the like discharged from the beverage manufacturing apparatus in a receiver or the like, the lid of the electric heat retaining pot was opened and the container was transferred from the receiver to the inner container. Therefore, the operation is complicated, and this operation must be performed every time the 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. There was a problem that it faded.

[0005] The present invention has been made to solve such a problem, and it is possible to directly inject a liquid from a beverage production apparatus into an inner container, and to carry out the operation with a very simple operation. An object of the present invention is to provide an electric heat-insulating pot that is excellent in heat-insulating effect.

The discharge unit 8 includes a unit pipe 48 forming a liquid passage, a valve element 49 for closing and opening the liquid path in the unit pipe 48, a lever 50 for operating the valve element 49 from the outside front, and a valve element 49. 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. Reference numeral 47 denotes 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 heat retaining pot 1 is to be cleaned, or when the container from which liquid is stored is poured into the pot at once, the lid 5 can be opened. In addition, when pouring directly from a beverage production device such as coffee or tea into this pot, if the operation lever 29 is slid and the injection passage 24 is opened while the lid 5 is closed, the liquid from the beverage production device will be discharged. Injection passage 24 in lid
After the injection is completed, the operation lever 29 is slid in the opposite direction to close the injection passage 24.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to only the structures of the embodiments, but has the above-mentioned constitutional requirements of the present invention. The above-mentioned purpose can be achieved, and the present invention can be carried out with appropriate modification within a range having the following effects.
