Reference numeral 13 denotes a heat retaining lamp. Reference numeral 14 denotes a storage container for storing extracted coffee, tea, and the like. The power supply lamp 11 is lit when the heat retention lamp 13 described later is turned off to determine whether the power is on. The kettle tank 4 is closed at the top opening by a closed lid. The heater 3 is stretched at the lower part of the outer periphery, and is suspended inside the beverage brewing apparatus 1. The water in the water heater tank 4 is heated by the heater 3.

A water supply pipe 5 extending to the bottom of the water heater tank 4 is provided on the upper surface of the sealed water heater tank 4.
A steam vent pipe (not shown) for lowering the pressure in the sealed water heater tank 4 and a discharge pipe 7 are provided. The tip of the discharge pipe 7 is arranged above the basket 6 and below the upper surface of the water heater tank 4.
The rear end of the discharge pipe 7 is provided above the front end discharge port.

The position of the discharge port of the discharge pipe 7 is below the upper surface of the water heater tank 4, and the difference between the upper and lower ends thereof is filled with water at the same water level as the discharge port in the water heater tank 4. Is set to be equal to or higher than the height from the top of the water heater tank 4 having a volume that expands as hot water and increases in volume. Since the discharge port is located below the upper surface of the water heater tank 4, water is absorbed by the siphon phenomenon of the discharge pipe 7 and the water level is lower than the upper surface of the water heater tank 4 and the water level is full at the water inlet level. Becomes

Therefore, the water is quantified with an air layer above the water heater tank 4. After the water is filled, the water is heated by the heater 3 to make hot water. The hot water corresponding to the volume expansion of the water generated at the time of heating has an air layer in the upper part of the container of the water heater tank 4, so that the volume of the air layer is increased. Just fill with the hot water of the expansion,
Water does not leak from the discharge pipe 7. The basket 6 is formed in a funnel shape with a hole on the bottom surface, and after laying filter paper on the inside, coffee powder, tea leaves and the like are put.

As shown in FIG. 1, the basket 6 is detachably mounted on the front of the beverage brewing apparatus 1 and is slid from the front of the beverage brewing apparatus 1 with a handle.

In addition, this one heat retention lamp 1
Reference numeral 3 indicates the progress of each unit of the temperature control mechanism by blinking, lighting, and turning off.

When the extraction liquid is dropped, first, water is poured from the water supply tank 2 so that the water heater tank 4 becomes full, and when water starts flowing out of the discharge port of the discharge pipe 7, the water injection is stopped. Insert the plug 9 into the outlet,
When the power switch 10 is turned on, the power lamp 11 is turned on. When the power switch 10 is turned on, the temperature control mechanism operates to control the heater 3 to boil the water in the water heater tank 4 to a state close to boiling, and then maintain the water at a high temperature.

When the temperature becomes suitable for the extraction, the heat retention lamp 13 is turned on. Next, after the ingredients such as coffee powder and black tea leaves are set in the funnel-shaped basket 6 and inserted into the upper part of the front of the beverage extraction device 1, a required amount of water is poured into the water supply tank 2. Hot water is dripped from the discharge port of the discharge pipe 7 due to the siphon phenomenon, and raw materials such as coffee powder and tea leaves set in the basket 6 in advance become an extract through the filter paper and flow from the bottom of the basket 6.

FIG. 3 is a flow chart showing the temperature keeping state of the temperature control mechanism written in the microcomputer.
Is a lamp operation diagram showing a lamp on / off state, and the operation will be described based on these. First, when the heat retention temperature is set to 95 ° C. by operating the temperature control mechanism, the heat retention lamp 13 blinks while the water in the water heater tank 4 is boiling to a state close to boiling. Thereafter, when the temperature reaches 95 ° C., the heat retaining lamp 13 is turned on. When the heat retention lamp 13 is turned on, if the switch button 12 is pressed lightly, a 12-hour timer is turned on. As a result, the heat retention temperature becomes 5
The temperature is set to 0 ° C., and the heat retention lamp 13 blinks repeatedly to reduce power consumption. After 12 hours, the temperature automatically returns to 95 ° C.

Next, when the switch button 12 is pressed for three seconds or more in this low heat retaining temperature state, the apparatus automatically returns to the high heat retaining state of 95 ° C. When the switch button 12 is pressed for 3 seconds or more when the heat-retention lamp 13 is turned on in a high-temperature heat-retention state, the heat-retention lamp 13 is turned off and the heat-retention state is stopped. . Furthermore,
If the switch button 12 is pressed for three seconds or more when the heat keeping lamp 13 is turned off, the temperature automatically returns to the high temperature keeping state of 95 ° C.
