Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat retaining container for a beverage brewing machine in which a thin plate-shaped heat retaining heater is provided on the bottom of a glass inner container. [0002] Conventionally, a beverage brewing machine used for business use includes a water supply tank, a bottomed cylindrical water heater tank equipped with a heater, a water supply pipe connecting the water supply tank and the water heater tank, A chamber for setting coffee powder, tea leaves, etc., a discharge pipe that guides the boiling water in the water heater tank to the upper part of the chamber, an insulated container for storing the extract extracted from the bottom of the chamber, and an insulated container on which the insulated container is placed. When a desired water is supplied to the water supply tank, the water enters the water heater tank through a water supply pipe, and the water in the water heater tank is heated by the heater and boiled. Further, when predetermined water required for the water supply tank is added, additional water is supplied into the water heater tank through the water supply pipe, and the boiling water corresponding to the additional water in the water heater tank causes a siphon phenomenon. And discharged to the upper part of the chamber through the discharge pipe. After laying filter paper in this chamber, raw materials such as coffee powder and tea leaves are set, and the boiling water discharged from the upper part of the chamber is mixed with the raw material, and is dropped as an extract from the lower part of the chamber,
It is stored in the thermal insulation container. [0004] The insulated container is a single-bottle inner container made of glass for storing an extract of warm coffee, tea, etc. extracted from below the chamber, and a thin container stretched on the bottom of the inner container to keep the extract in the inner container warm. A heat retention heater of a flat mica heater,

The apparatus includes a liquid amount display mechanism, a driving unit for driving the ejection mechanism, a warming heater, and an electric circuit mechanism for operating the driving unit. [0005] However, in this type of heat retaining container for a beverage brewing machine, during the manufacturing process of the glass inner container, the inner container bottom is largely depressed toward the center inward. After cooling, the recessed part gradually descends so that the entire bottom surface becomes a horizontal plane. However, this cooling process operation is very difficult, and the entire bottom surface rarely becomes a horizontal surface, and the inner container bottom is often manufactured in a slightly concave shape toward the center inward. For this reason, the heat retention heater composed of a thin flat mica heater stretched on the bottom of the inner container cannot make uniform contact with the bottom of the inner container. There is a problem that the extract such as coffee or tea in the inner container close to the contact point is particularly intensively heated, and the fragrance is deteriorated, resulting in poor coffee or tea as a whole. Accordingly, the present invention has been made to solve the problem of such a conventional heat retaining container for a beverage brewing machine, and it is intended to improve the thermal efficiency of a heat retaining heater stretched on the bottom of an inner container. It is an object of the present invention to provide a heat retaining container for a beverage extractor for heating an extract in an inner container as a whole to obtain an extract such as coffee or tea having a good aroma.
