Next, the knob 25 is rotated to adjust the multi-stage wattage converter 25 to set the heating temperature of the electric heater 26 to boil the cold water in the conduit 142. At this time,
Since a check valve 143 is provided in front of the conduit 142, the boiling water passes through the conduit 144 and reaches the bottom surface 11 of the canopy.
Flow tea leaves into the teapot 3 from the outlet 113 in the center of the teapot 2. In this way, one side of the heating conduit gradually becomes a vacuum, and the other side continues to release water through the check valve 143.
After heating while supplying water until the water supply stops, the power switch 22 can be turned off. If you want to make tea again, press the handle 156 to supply cold water, then turn on the power switch 22 to heat it.

The boiling water continuously flows into the teapot 3 to soak the tea leaves, and when the water level rises and reaches the top of the curved part 355 of the siphon tube 35, a siphon effect occurs, and the tea water that has soaked the tea leaves flows through the siphon tube. 35, the tea water flows into the tea water container 4 placed on the bottom heat insulating plate 121 below and is used for drinking. In this case, the tea water container 4 is placed on the bottom heat insulating plate 121, so that the tea water is kept warm to some extent.

Also, when the tea water container 4 is removed from the heat insulating plate 121,
A water receiving device 5 located near the tea water container 4
will immediately twist beneath the outlet 354 of the siphon tube 35 and will receive any residual water droplets from the siphon tube 35.

[Effect of idea]

Summarizing the above, this idea has the following advantages.

(1) With constant water supply heating, tea is added once each time it is heated, so there is no need to add water multiple times.

(2) It is possible to accurately set the tea brewing time depending on the type of tea leaves, so there is no need to make judgments based on experience, and the umami flavor can be enjoyed without losing the fragrant flavor of tea.

(3) After the accurately set tea brewing time is over, the tea is automatically transferred to the tea water container, so there is no need to transfer it to another container as in the past, which saves time and effort.
