As shown in the figure, a water container 1 is provided with a heating device 2, and a basket is provided with a saucer 5 on top of the water container 1, which has a built-in filter 3 and a spout 4 for pouring the filtrate out of the container. 6 is detachably provided, a water riser pipe 7 is provided that communicates the water container 1 and the basket 6, and a water spray part 9 is provided above the water riser pipe 7 and integrally formed with a basket lid 8.

要で、器体はコンパクトにできない欠点を有していた。In the coffee boiler with this configuration, the water put in the water container 1 is heated, and as the water temperature rises, the pressure inside the water container 1 becomes high.
Hot water passes through the water riser pipe 7 and drips onto the coffee powder stored on the filter 3 in the basket 6, extracts the coffee components, passes through the saucer 5, and is led out of the container from the spout 4, and then into the pot. However, since a separate bot 10 is required and the bot 1o is misplaced,
Furthermore, if the pot 10 is not positioned properly, the table will be soiled. Furthermore, since the finished coffee liquid is stored in a separate container, there is a problem that the coffee liquid cools down. In order to prevent the coffee liquid from cooling, a heat-retaining stand equipped with a heat-retaining heater was required, and the device had the disadvantage that it could not be made compact.

るなどの問題があった。Furthermore, since the inside of the water container 1 is sealed, the heating device 2
The water in the heated water container 1 does not boil but passes through the water riser pipe 7 at a low temperature and splashes onto the coffee grounds, making it impossible to extract the ingredients of the coffee grounds sufficiently, resulting in extremely bad tasting coffee. . Furthermore, when all the water rises from the water container 1 through the water riser pipe γ and into the basket 6, the inside of the water container 1 becomes air-stinging and the temperature rises rapidly, which may deteriorate the heating device 2 and deform the container body. arise. On the other hand, if the lower end opening of the water riser pipe 7 is located at an appropriate distance from the bottom of the water container 1, the water will remain in the water container 1 even after the water rises, preventing the temperature from rising; Because of this, the time it takes to turn off the power with the thermostat etc. is not constant, and considering the variation in temperature sensing, the thermostat may operate too quickly and turn off the power before the specified level of water rises, or the time at which the power is turned off may vary. There were problems with the length, which increased the risk of deformation of the vessel body and deterioration of the heating device.

で、コンパクトで安価な器具を得られる。Next, the basket lid 52 is placed on the basket 28, the magnetic plug 27 is placed in the plug receiver 26, and the manual return type thermostat 55 is closed. Then heater 1
5, electricity is started and the water in the water container 11 is heated. At this time, the drip port 36 of the valve 39 of the pressure valve 37 remains open because the amount of generated steam is small. As the heating continues, the water temperature rises to near the boiling point or when it boils, the amount of steam generated increases rapidly, more steam passes between the valve seat 38 and the valve 39, and the valve 39 is pushed upward. The dripping port 36 is closed. Then, the pressure inside the water container 11 rises and hot water flows into the rising pipe 4.
2, hits the sprinkler lid 44, spreads downward, and is evenly poured into the coffee grounds. Here, since the water temperature sensor 18 is configured to close near the boiling point, it is always activated, the water temperature sensor 18 closes, and the auxiliary heater 66 starts to be energized. When the auxiliary heater 56 of the delay timer 54 heats up, the manual return thermostat 55 opens the circuit after a certain period of time, so the power is turned off. That is, hot water is poured through the water riser pipe 42 due to the pressure inside the water container 11, the water in the water container 11 decreases, and water remains below the lower end of the water riser pipe 42 at 1-1. Even if the temperature inside the container 11 hardly rises above the boiling point, the power is surely turned off after a certain period of time, the inside of the water container 11 is cooled, and the pressure inside the water container 11 becomes atmospheric pressure and the coffee liquid in the basket 28. When the water head becomes lower than the water head, the water is dripped into the water container 11 from the dripping port 35 and stored. In this way, only boiling or near-boiling hot water is poured into the coffee grounds in the basket 28, so that economical coffee with good extraction efficiency and high aroma can be obtained. After a certain period of time when the water temperature detector 18 detects the optimum temperature for extraction, the power is turned off, allowing water to remain in the water container 11, thereby preventing deformation of the container body and deterioration of the heating device 12 due to temperature rise. In addition, in order to reduce the variation in the contact time between coffee powder and hot water, that is, the extraction time,
You can always get delicious coffee liquid. In addition, after the extraction is finished, the extract is not poured out of the container, but returns to the heated water container, so the temperature decreases less and a coffee liquid suitable for high-temperature beverages is obtained. No containers are required, resulting in a compact and inexpensive device.
なお、遅延タイマーの設定時間は、水容器内の水位が昇

ばよい。The time set for the delay timer may be such that the power is turned off when the water level in the water container does not reach the lower end opening position of the water riser pipe.In short, the circuit of the heating device may be opened while water remains.

ぎ、安全性の向上をはかるものである。Effects of the Invention As is clear from the above embodiments, the coffee boiler of the present invention has a basket on top of a water container equipped with a heating device, and this basket has a built-in filter and a drip opening for dripping into the water container. and a pressure valve at the drip opening, a water riser pipe with one end opening near the bottom of the water container and the other end opening at the top of the basket, and a water temperature sensor installed in the water container. By setting a delay timer that operates in conjunction with this water temperature sensor and opening or switching the circuit of the heating device, the water in the water container rises to the boiling point or near boiling point for efficient extraction. Since the circuit is controlled reliably, it operates reliably and does not fail, and reduces variation in brewing time so that you can always get delicious coffee.It also prevents excessive temperature rise and ensures safety. It is intended to improve.
