Description

[Detailed Description of the Invention] Industrial Field of the Invention [0001] The present invention relates to a decoction device for decoctioning Chinese medicine to make a decoction.

Generally, when decoctioning Chinese herbs, water and herbs were placed in a container, which was heated over low heat for a long time and boiled down.

However, when decocting a Chinese herbal medicine, a strong odor is generated together with steam, which fills a wide range and gives a strong discomfort to the surrounding people.

Therefore, it is preferable to suppress the emission of steam as much as possible and suppress the generation of odor, but on the other hand, the odor during decoction is a heavy element of Kampo medicines as a vapor, and odor is generated as needed during decoction. It is preferable that it can be inhaled.

2. Description of the Related Art Conventionally, when decocting Chinese herbs, containers such as earthen bottles have been used.

Problems to be Solved by the Invention However, these containers cannot prevent a strong odor.

In addition, although some decoctioners have been proposed in which the generated vapor is condensed and recirculated into the container to suppress the generation of odors, it has a structure that cannot absorb odors, The structure is complicated and the operation is difficult,
It was not satisfactory.

The present invention has been made in view of the above circumstances, and provides a novel decoction of a herbal medicine that can suppress the generation of an odor when decoctioning a herbal medicine as much as possible and can also inhale the odor if necessary. It is intended.

Means for Solving the Problems Thus, in the Chinese medicine decoction device of the present invention, a double lid formed by detachably fitting an outer lid to an inner lid is fitted to an upper opening of a container provided on an upper part of a heater, A ventilation space is formed between the inner lid and the outer lid of the double lid, and an exhaust hole is formed on the upper surface near the outer peripheral edge of the double lid, and the container is provided on the bottom of the inner lid at a position away from the exhaust hole. It is characterized in that a communicating reflux port is formed, and the bottom of the inner lid is formed in a substantially funnel so that the position of the reflux port is the lowest.

Further, in this Chinese medicine decoction device, a ventilation hole is formed in a position close to the exhaust hole in the inner lid of the double lid, and when the outer lid is fitted, the ventilation hole is closed by the outer lid. It is preferable to provide a temperature sensor exposed to the ventilation space at a position close to.

The coil 16 of 14 and the connector 5 are connected, and the temperature sensor 9 is connected between the connectors 5 via the connector 10.
Is installed.

When the connectors 5 and 10 are not connected, the coil 16 is not energized even if the main switch 12 is turned on, and the contacts
When the main switch 12 is turned on while the connectors 5 and 10 are connected, the coil 16 is energized, and the contact 15 is closed and the heater 4 is energized to generate heat. It is like this. When the temperature sensor 9 is heated to a predetermined temperature and the contacts are opened, the coil 16 is de-energized, the contacts 15 are opened, and the heater 4 is de-energized.

Next, 17 is a double lid fitted in the upper opening of the container body 7 and is composed of an inner lid 18 and an outer lid 19.
A ventilation space 20 is formed between the outer cover 19 and the outer lid 19.

The inner lid 18 has a short tubular portion on the outer circumference of a substantially funnel-shaped bottom 21 with a depressed center.
22 is provided upright, and a reflux port 23 communicating with the inside of the container 6 is bored at the lowest position of the bottom portion 21. A cutout 24 is formed in the rear portion of the short tubular portion 22, and the temperature sensor 9 is exposed in the inner lid 18 from the cutout 24. A vent hole 25 is formed in the bottom portion 21 near the temperature sensor 9, and a cover portion 26 is formed inwardly from the upper end of the short tubular portion 22 at the upper portion thereof, and the cover portion 26 is provided with the cover portion 26. Has an exhaust hole 27.

Further, a fitting protrusion 28 is provided on the outer lid 19 so that when the outer lid 19 is fitted to the inner lid 18, the fitting protrusion 28 fits into the ventilation hole 25 and closes. Has become.

Reference numeral 29 denotes an inner container housed in the container body 7, which has a large number of small holes 30 formed on the bottom surface and the peripheral surface thereof, and slanting blades 31 radially project on the lower surface of the bottom portion. .

To use this Chinese medicine decoction device 1, herbs are placed in the inner container 29 and stored in the container 6, water is put therein, and the double lid 17 is fitted. Then, the container 6 is placed on the heating plate 3 and the connector 10
Connect to connector 5 and switch on. This causes the heater 4 to generate heat and heat the water in the container 6,
Extract the active ingredients of the herbs in 29.

When the temperature of the water in the container 6 becomes high and the convection becomes violent, the inner container 29 is rotated while floating in the water by the action of the blades 31, the water and the herbs are stirred, and the extraction is promoted.

In the present invention, it is preferable that the inner container 29 is provided with the blades 31 and the inner container 29 is rotated to stir the water and the herbs as described above, but this structure is not always a necessary requirement. Also, the case of providing a means for stirring water and herbs is not limited to the above structure. For example, it is possible to project an annular rib on the bottom outer peripheral lower part of the inner container 29, guide bubbles generated by boiling water into the inner container 29, and stir the water and the herbs with the bubbles.

In the present invention, when the temperature of the water in the container 6 rises and starts to boil, the steam enters the ventilation space 20 through the reflux port 23. Then, the lower surface of the outer lid 19 is touched, cooled, condensed, flows through the substantially funnel-shaped bottom portion 21, is collected at the position of the reflux port 23, and is refluxed again into the container 6 from the reflux port 23.

As shown in the drawing, by forming irregularities on the inner surface of the outer lid 19, the steam is strongly cooled and condensation is promoted.

When the boiling becomes intense and the cooling by the outer lid 19 can not catch up, the steam flows toward the exhaust hole 27 as shown by the arrow,
It is discharged from the exhaust hole 27. Then, the temperature sensor 9 is touched in the middle of the process, the temperature sensor 9 detects the heat, the power supply to the circuit is cut off, and the heat generation of the heater 4 is stopped.

When the heating of the water in the container 6 is stopped and the generation of steam is reduced, the steam in the ventilation space 20 is cooled by the outer lid 19 and condensed. Therefore, the inside of the ventilation space 20 is decompressed and the outside air is exhausted.
Inhaled from 27, the cool air touches the temperature sensor 9. Then, the temperature sensor 9 detects the cool air and re-energizes the heater 4 to restart the heating.

In this process, since the vent hole 25 is closed by fitting the fitting protrusion 28, all the vapor in the container 6 enters the vent space 20 from the reflux port 23, and the vent space 20 is filled with the vapor. Only after that, the temperature sensor 9 is activated. When the vapor in the ventilation space 20 is slightly cooled, the temperature sensor 9 is activated immediately by the cold air sucked from the exhaust hole 27. Therefore, the water in the container 6 is always maintained at the boiling point, and the active ingredient of the herb is efficiently extracted.

Further, if the vapor is sufficiently filled in the ventilation space 20 and the excessive vapor starts to be discharged from the exhaust hole 27, the temperature sensor 9 is immediately activated to stop the heating, so that the components are excessively extracted while effectively extracting the components. There is no boiling down, and no more odor is emitted than necessary.

Next, when the outer lid 19 is removed from the inner lid 18, as shown in FIG. 2, the vapor in the container 6 is discharged from the reflux port 23, and the face of the inner lid 18 should be brought close to the top to inhale the vapor of Chinese herbal medicine. You can

Further, since the fitting projection 28 is detached and the vent hole 25 is opened, a part of the steam of the container 6 is discharged from the vent hole 25, and the cover portion 26 collects the steam around the temperature sensor 9 and the temperature sensor 9 is exposed. Boiling detection is performed reliably by touching. If the cover 26 is not provided, when the outside air temperature is low, the temperature sensor 9 cannot detect boiling when the outer lid 19 is removed, and there is a risk that the herbs will be overcooked. Therefore, by providing the cover portion 26, the temperature sensor 9 operates reliably even when the outer lid 19 is removed, and the boiling of water can be reliably detected.

Effect of the Invention According to the present invention, therefore, the water is not heated more than necessary while being kept at the boiling point, and is heated for a long time with low heat to decoct, and the extract is not excessively boiled down. Further, since most of the generated vapor is recirculated, odor emission can be suppressed to the minimum.

Particularly in the device of claim 2, this effect is remarkable.

Further, by removing the outer lid 19 from the inner lid 18, it is possible to positively release the odor and inhale it, and it is possible to sufficiently exert the effect as a vapor.
