Description

  The present invention is an invention related to a traditional Chinese medicine decoction device which can easily decoct Chinese medicine mainly in a general household.

  Chinese herbal medicine is generally a method in which water and chemicals are placed in a container and heated for a long time. Traditionally, decocting using a bottle or the like has been a common method. However, since the Chinese medicine has different heating time and heating temperature depending on the type of the drug, the management of the heating time and the adjustment of the heating are difficult. In order to solve this problem, an electric heating Chinese herbal decoction device has been devised as disclosed in, for example, Patent Document 1 and Patent Document 2 so that the temperature and time can be easily set. .

Patent Documents 1 and 2 disclose structures for condensing and refluxing the steam generated when decocting without dissipating. Specifically, the lid is composed of an inner lid and an outer lid, and the vapor containing the medicine is condensed in the space formed by the inner lid and the outer lid and is returned to the container. In the inventions described in Patent Documents 1 and 2, a chemical liquid generated as vapor is condensed and refluxed by attaching an outer lid, and the outer lid is removed and the vapor can be sucked.

Herbal medicines used by decoction have different physical properties depending on the type of drug. In particular, in the case where the viscosity of the decocted chemical solution is high, such as a megsuroki, there is a drawback that a large amount of bubbles are generated by boiling and easily blown. This phenomenon also occurred in the products of the inventions described in Patent Documents 1 and 2, and it was necessary to take measures such as lowering the heating temperature to weaken the boiling state and removing the lid to prevent spilling.
In view of the above-mentioned disadvantages of the prior art, the present invention is a Chinese herbal medicine that can be used with peace of mind without causing spilling as much as possible, and that does not dissipate chemicals as a vapor, even when decocting a drug that tends to spill. The purpose is to realize a decoction.

The present invention comprises a heater 1 provided with a heater 2 and a container 3 with a lid, and improves a traditional Chinese medicine decoction device that heats water or medicine contained in the container 3 by the heater 2 of the heater 1. is there.
In order to achieve the above object, according to the present invention, the lid attached to the upper end opening of the container 3 is composed of the lower lid 4 and the upper lid 5, and the upper lid 5 is detachable from the lower lid 4. In addition, the upper part of the lower lid 4 is airtightly covered and a relatively large cooling space 6 is formed by the lower lid 4 and the upper lid 5, and the cooling space 6 and the inside of the container 3 communicate with each other and are generated in the cooling space 6. An air passage 7 is formed in the lower lid 4 so that the condensed liquid can be refluxed into the container 3. Further, formed between gap between the inner peripheral surface of the outer peripheral surface and the container 3 of the lower lid 4 which is inserted into the container 3.

Lower lid to form a gap, and the flange 4a in contact with the upper edge of the container 3, and a small diameter portion 4b which is inserted into the container 3, the inner peripheral surface of the container 3 to the lower part of the small diameter portion 4b and A large-diameter portion 4c formed so as to hold a slight gap X between them, and a through hole 8 is formed in a part of the side surface of the small-diameter portion 4b . As a result, the bubbles that have moved upward from the gap X between the lower lid 4 and the inner periphery of the container 3 flow into the upper portion of the lower lid 4 from the through hole 8 .

According to the second aspect of the present invention, a knob 9 is formed on a part of the lower cover 4 and a handle 10 is formed on a part of the upper cover 5, and the lower cover 4 and the upper cover 5 are freely fitted at a specific plane rotation angle position. The engaging means for engaging the upper cover 4 and the lower cover 5 by rotating the upper cover 5 in a plane is provided.

According to the third aspect of the present invention, the lower lid 4, specifically, the bottom surface portion 4 d of the lower lid 4 is formed in a funnel shape, and a bulging portion 11 protruding upward is formed at a substantially central position thereof.

The container 3 is made of transparent glass so that the inside of the stored medicine and the like can be seen, and a container handle 18 is fixed to the back portion, and a spout 19 is formed at the upper front end facing the container handle 18. Yes. The container handle 18 is fixed by engaging the upper locking portion 18a with the upper end of the container 3 and fastening the steel belt 20 with screws 26 at the lower end. A lid is attached to the upper end opening of the container 3 so that heat and steam can be roasted without escaping.

  As understood from FIGS. 2 and 3, the lid includes a lower lid 4 that is attached to the upper end opening of the container 3 and an upper lid 5 that is detachably attached to the lower lid 4. As shown in FIG. 2, the lower lid 4 has a flange portion 4a that comes into contact with the upper end opening of the container 3, a small diameter portion 4b that is inserted into the container 3, and a lower end portion of the small diameter portion 4b. Is provided with a large-diameter portion 4c that is expanded downward and has a funnel-shaped bottom surface portion 4d at the lower end of the small-diameter portion 4b. The diameter of the large diameter portion 4c is a slight gap of about 1 to 2 millimeters between the inner surface of the container 3 and the diameter of the small diameter portion 4b is about 8 to 10 millimeters between the inner surface of the container 3 and the inner diameter. A relatively large gap is formed. An upper cylindrical portion 4e having a diameter slightly larger than that of the narrow diameter portion 4b is formed above the flange portion 4a so as to form a relatively large capacity saddle shape as a whole. An annular ridge 22 is formed on the outer peripheral surface of the upper cylindrical portion 4e by partially cutting it. As shown in FIG. 5, the notches 23 of the protrusion 22 are formed at three locations at substantially equal intervals.

  At the center position of the bottom surface portion 4d formed in a funnel shape, a cylindrical bulged portion 11 that protrudes upward is formed, and a part of the side wall of the bulged portion (four locations on the drawing) is cut through. A hole 7a is arranged to form an air passage 7 through which steam in the container 3 passes as shown by an arrow in FIG. The specific shape of the air passage 7 is not particularly limited, but when the cylindrical expanded portion is formed as in the illustrated embodiment and the side wall is cut away to form the through hole 7a. The steam and bubbles generated in the container 3 are ejected from the center toward the side.

As shown in FIG. 2, a part of the large-diameter portion 4c is omitted and a pair of vertical locking walls 4f are provided on the back surface of the lower lid 4, and the support plate 21 is provided in the vicinity of the flange portion 4a. A rib 9 is arranged on the upper surface of the support plate 21. The locking wall 4f is fitted into the locking portion 18a of the container handle 18 engaged with the upper end of the container 3, and the support plate 21 is supported by the upper end of the container handle 18. With the above structure, the lower lid 4 is attached to a predetermined position of the container 3 without loose rotation.
As can be understood from FIG. 3, a part of the side wall of the small diameter portion 4b is cut out to form a horizontal rectangular through hole 8 on the front side of the lower lid 4.

  The upper lid 5 attached to the lower lid 4 has a cap shape that fits into the upper cylindrical portion 4e of the lower lid 4 and has a handle 10 protruding from the upper surface. As understood from FIGS. 1 and 6, one end of the handle 10 is extended outward, and the extension portion 10 a is formed in a hollow shape to cover the knob 9 of the lower lid 4 and the upper lid 5 to the lower lid 4. The handle 9 is hidden in the state of being attached to the handle 10, and the appearance of the handle 10 including the extension 10 a is summarized as an aspect continuous with the container handle 18, and has been devised in design.

  On the inner peripheral surface of the upper lid 5 formed in a cap shape, protrusions 24 are formed at three substantially equal intervals as shown in FIG. Therefore, as shown in FIG. 7, the position of the notch 23 formed in the protrusion 22 of the lower lid 4 and the position of the protrusion 24 formed on the inner peripheral surface of the upper lid 5 are aligned, and the upper lid is When 5 is inserted and the upper lid 5 is rotated, the protrusion 24 enters the lower surface of the protrusion 22 (see FIG. 8), and the lower lid 4 and the upper lid 5 are set integrally. At this time, as shown in FIGS. 7 and 8, the range in which the upper lid 5 can be rotated is a range in which the knob 9 of the lower lid 4 can move freely in the extension portion 10 a of the handle of the upper lid 5, and a protruding shape. A stopper 25 for preventing over-rotation is formed on the lower surface of 22. Further, as shown in FIG. 9, a part of the lower lid 4 is engaged with a container handle 18 fixed to the container 3, so that it does not move and the lower lid 4 is attached. It can be securely attached and detached with only the upper lid 5.

  When the medicine and water are put into the container 3 and decocted using the Chinese herbal decoction device of the embodiment shown in FIG. 1, the generated steam is passed through the air passage 7, specifically, the through-hole 7 a formed in the inflated portion 11. And flows into the cooling space 6 formed by the lower lid 4 and the upper lid 5, and the chemical solution condensed in the cooling space passes through the bottom portion 4 d of the lower lid formed in a funnel shape and enters the container 3 from the air passage 7. Flows in. At this time, the gap X between the large-diameter portion 4c of the lower lid and the inner peripheral surface of the container 3 is small, and the small-diameter portion 4b, the inner peripheral surface of the container 3 and the flange of the lower lid are located above the gap X. Since a relatively large space is formed by the portion 4a, steam leakage from the outer peripheral portion of the lid is prevented by a kind of labyrinth effect. However, the outer peripheral portion of the lid is not airtightly closed, and for example, a situation in which the vapor pressure in the container 3 rises abnormally due to part of the vapor escaping from the gap of the spout 19 is avoided. be able to.

When the top lid 5 is removed from the state shown in FIG. 1 and a chemical that easily produces bubbles such as a swordfish is decocted, the foam filled in the container 3 passes through the ventilation path 7 as shown in FIG. It accumulates on the upper surface and is cooled and disappears by touching the outside air on the upper surface of the lower lid 4. The chemical solution generated by the disappearance of the bubbles is returned to the container 3 through the air passage 7.
The gap between the outer periphery of the lower lid 4 and the inner surface of the container 3 is such that bubbles do not easily pass through the small gap X, but the bubbles that pass through the gap X are narrow diameter portions of the lower lid 4. It enters the upper surface of the lower lid 4 through the through hole 8 formed in 4b. That is, the bubbles that have entered the space formed by the narrow diameter portion 4b, the inner peripheral surface of the container 3 and the collar portion 4a of the lower lid through the gap X have no escape space, so Flows to the top.

10 to 12 show an embodiment in which the structure of the air passage 7 formed in the lower lid 4 is changed.
The bottom surface portion 4d of the lower lid 4 is formed in a funnel shape, a cylindrical bulged portion 11 is formed at the center thereof, and a through hole 7a is formed in a part of the side wall of the bulged portion 11 so that a ventilation path is formed. And a mesh member 15 is interposed in the air passage 7. Specifically, a mesh member 15 is stretched on the outer peripheral surface of the bulged portion 11. A cylindrical cap 14 having an upper end outer collar 12 is rotatably mounted on the bulged portion 11 on which the mesh member 15 is pasted. The cylindrical cap 14 has a through hole 13 formed at a position where it can coincide with the through hole 7a formed in the bulged portion 11. Then, as shown in FIG. 12, the air passage 7 is formed by rotating the cap 14 so that the rotation positions of the through hole 7a and the through hole 13 coincide. Thereby, the ventilation path 7 with the mesh member 15 interposed is completed. In this embodiment, the area ratio corresponding to the through-hole 7a formed in the bulged portion is changed by rotating the cap 14, and the size functioning as the air passage 7 is changed. That is, the size of the ventilation path can be changed according to the type and prescription of the medicine.

In this embodiment, when the medicine is decocted with the lower lid 4 and the upper lid 5 set, all the generated vapor passes through the ventilation path 7 and enters the cooling space 6 formed by the lower lid 4 and the upper lid 5. This and Kino vapor to pass mesh member 15, thereby removing them also include drug itself vapor or bubbles, cooling is facilitated by the stirring effect of the vapor by the mesh member 15. In particular, since the steam discharged from the through hole 7a formed in the side wall of the bulged portion 11 is ejected toward the side in the cooling space 6, the stirring effect is promoted. In this manner, condensate steam is cooled and condensed, you reflux vent path 7 into the container 3 along the bottom surface portion 4d of the lower lid 4 is funnel-shaped.

  The cap 14 attached to the swelled portion 11 has the effect of dividing the cooling space 6 into two vertically by providing the upper end outer casing 12. That is, the steam ejected from the air passage does not immediately rise but is guided in the outer peripheral direction by the presence of the upper end outer casing 12 of the cap 14 and is cooled to some extent at the outer peripheral portion of the cooling space, so that the top cover 5 having the greatest cooling effect. Since it contacts the inner surface, the cooling effect as a whole can be improved.

When brewing the easy agent bubbles are generated is used to remove the upper lid 5. When the medicine is decocted in a state where the upper lid 5 is removed, the generated bubbles are ejected to the upper surface of the lower lid 4 through the air passage 7, but at this time pass through the mesh member 15. Therefore, a part of the large bubbles are broken and become liquid, and the medicine itself that has risen together with the bubbles is removed, and relatively fine bubbles accumulate on the upper surface of the lower lid 4. Then, the lower heat is blocked by the upper end outer casing 12 of the cap, and the upper bubbles in contact with the outside air are sequentially cooled and liquefied, and return to the container 3 through the ventilation path 7. Therefore, even when a chemical that easily generates bubbles is decocted, it is possible to effectively prevent the bubbles from overflowing.
