DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1 is a perspective view of the embodiment of the present invention, FIG. 2 is a longitudinal sectional view of the embodiment of the present invention, FIG. 3 is a flowchart showing a heat insulation state of the embodiment of the present invention, and FIG. It is a lamp operation figure which shows a lighting and light extinction state.
The beverage extraction device 1 is used particularly for office use, and includes a water supply tank 2 with a lid, a water heater tank 4 provided with a heater 3, a water supply pipe 5 connecting the water supply tank 2 and the water heater tank 4, After boiling the water in the water heater tank 4 by controlling the heater 3 and the funnel-shaped basket 6 for setting the raw materials such as coffee powder and tea leaves, the discharge pipe 7 for guiding the high temperature water in the water heater tank to the upper side of the basket 6 It consists of a main board 8 by a microcomputer having a temperature control mechanism for maintaining the temperature and a plug 9 for power supply.
[0007]
10 is a power switch provided above the rear part of the beverage extractor 1, 11 is a power lamp that is turned on when the power switch 10 is turned on, 12 is a switch button for operating the heat-retaining state in the water heater tank 4, and 13 is heat-retaining. It is a lamp. Reference numeral 14 denotes a storage container for storing extracted coffee, tea and the like. This power lamp 11 is turned on to eliminate whether the power is on when a heat retaining lamp 13, which will be described later, is turned off.
The water heater tank 4 is hermetically sealed with a hermetic lid, and the heater 3 is stretched on the lower part of the outer periphery and is suspended in the beverage extraction device 1. The water in the water heater tank 4 is heated by the heater 3.
[0008]
On the upper surface of the sealed water heater tank 4, a water supply pipe 5 extending to the bottom of the water heater tank 4, a steam release pipe (not shown) for lowering the pressure in the sealed water heater tank 4, and a discharge pipe 7. And are provided.
The tip of the discharge pipe 7 is disposed above the basket 6 and below the top surface of the water heater tank 4. The rear end of the discharge pipe 7 is provided above the discharge port at the front end.
[0009]
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 of the discharge pipe 7 is filled with water at the same water level as the discharge port in the water heater tank 4. Thus, the volume expands and is set to be higher than the height from the upper part of the water heater tank 4 with an increasing volume.
Since the discharge water level of the water heater tank 4 is 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 filled below the upper surface of the water heater tank 4 at the height of the suction port. It becomes.
[0010]
Therefore, it is quantified with an air layer above the water heater tank 4. After the water is full, the water is heated by the heater 3 to form hot water. Since the hot water corresponding to the volume expansion of the water generated at the time of heating has an air layer in the upper portion of the water tank 4, Only the hot water for expansion is filled, and no water leaks from the discharge pipe 7.
The basket 6 is formed in the shape of a funnel with a hole in the bottom. After a filter paper is laid on the inside, coffee powder, tea leaves and the like are placed.
[0011]
As shown in FIG. 1, the basket 6 is detachably attached to the front portion of the beverage extraction device 1. The basket 6 is slid from the front of the beverage extraction device 1 with a handle, and the basket 6 is disposed at the upper center of the discharge pipe 7. The discharge port is sandwiched and held so as to be positioned. The storage container 14 may be a thermos for storing the extract from the lower part of the basket 6 or may be a glass single bottle.
[0012]
The main board 8 is provided with a temperature control mechanism for controlling the heater 3 by a microcomputer to boil the water in the kettle tank 4 to a state close to boiling, and then maintaining a high heat retention temperature such as 95 ° C., for example.
This temperature control mechanism is interlocked with the switch button 12 and the heat-retaining lamp 13 by a microcomputer, maintains the high-temperature water in the water heater tank for a preset time from the high-temperature state to the low-temperature state, and then returns to the high-temperature state. The operation means is operated by the switch button 12 and the heat retaining lamp 13.
[0013]
In addition, the temperature control mechanism is also operated by the switch button 12 and the warming lamp 13 for the warming stop means for stopping the warming operation of the hot water in the hot water tank maintained at the warming temperature after boiling. Further, the temperature control mechanism operates the high temperature return operation means for preferentially returning to the high temperature state regardless of whether the heat retention is stopped or during the low temperature maintenance operation means by the switch button 12 and the heat insulation lamp 13.
[0014]
Although this one switch button 12 operates the low temperature maintaining operation means and the high temperature return operation means of the temperature control mechanism, it is possible to operate the heat retention stop means of the temperature control mechanism without any problem.
Further, this one heat retention lamp 13 displays the progress of each means of the temperature control mechanism by blinking, turning on and off.
[0015]
In the extraction of the extract, first, water is poured from the water supply tank 2 so that the water heater tank 4 is full. When water begins to be discharged from the discharge port of the discharge pipe 7, the water injection is stopped and the plug 9 is inserted. 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 is activated to control the heater 3 to boil the water in the kettle tank 4 to a state close to boiling, and then maintain the temperature at a high temperature.
[0016]
When the temperature is suitable for this extraction, the heat retention lamp 13 is turned on. Next, after setting the raw materials such as coffee powder and tea leaves in the funnel-shaped basket 6 and inserting it into the upper part of the front of the beverage extraction device 1, when the required amount of water is injected into the water supply tank 2, only the injection amount is injected. Hot water is dripped from the discharge port of the discharge pipe 7 due to the siphon phenomenon, and the raw materials such as coffee powder and tea leaves previously set in the basket 6 flow from the bottom of the basket 6 as an extract through the filter paper.
[0017]
FIG. 3 is a flowchart showing the heat insulation state of the temperature control mechanism written in the microcomputer, and FIG. 4 is a lamp operation diagram showing the 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 boiled to a state close to boiling. Thereafter, when the temperature reaches 95 ° C., the heat retention lamp 13 is turned on. If the switch button 12 is lightly touched when the heat-retaining lamp 13 is lit, a 12-hour timer is entered. As a result, the heat insulation temperature is set to 50 ° C., and the heat insulation lamp 13 repeats blinking to suppress power consumption. After 12 hours, the temperature automatically returns to 95 ° C.
[0018]
Next, when the switch button 12 is pressed for 3 seconds or longer in this low temperature keeping temperature state, the temperature automatically returns to the 95 ° C. high temperature keeping state. In addition, when the heat retention lamp 13 is lit in a high temperature heat retention state, if the switch button 12 is pressed for 3 seconds or more, the heat retention lamp 13 is turned off and the heat retention state is stopped. . Furthermore, if the switch button 12 is pressed for 3 seconds or longer when the heat-retaining lamp 13 is turned off, the heat-retaining state of 95 ° C. is automatically restored.
