CONSTITUTION:When the replacement time for tea leaf comes, a geared motor 15 is electrified, and the used-up tea leaves are discharged through the reversal of a tea filter 16 by a tea leaf replacement device 14. A hot water supply valve 11 is electrified simultaneously with the time when the new tea leaves are received on a filter 23, and hot water is supplied to the tea leaves on the filter 23 from a tank 8 through a hot water supply pipe 10 and a hot water supply port 12. A drink which flows out from the filter 23 does not flow out as it is from a funnel 18, and is temporarily allowed to stay in the funnel 18 by closing one between two holes 19a and 19b formed on the bottom surface. Accordingly, the vapor which is generated from the hot water surface of the drink moistens the tea leaves on the filter 23, and the extraction efficiency is improved, and the flavor-rich tea having high concentration can be extracted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a brewing device used in automatic tea dispensers and the like.

BACKGROUND OF THE INVENTION In recent years, tea dispensers such as those shown in Japanese Utility Model Publication No. 58-33943, which store hot water in a tank and supply a predetermined amount of hot water to tea leaves to brew tea, have become widespread. . Third
The figure shows a conventional tea brewing device. 1 is a funnel, 2 is a mesh filter having an opening on the top surface, and 3 is a filter 2 supported on the inner surface of the funnel 1.
It is a guide tube formed so that it can be fixed to the plate 5 by pressing the locking portion 4 at a predetermined position on the outer periphery and rotating and locking the locking portion 6 provided on the plate 5 in the circumferential direction. .

The operation of the extraction device configured as above will be explained below.

During beverage extraction, a certain amount of tea confectionery raw material discharged from the tea canister hopper is placed on the filter 2, and a certain amount of hot water is supplied into the extraction container to extract the beverage, which is placed directly below the extraction container. The beverage that passed through the cup filter was poured directly into the cup.

Problems to be Solved by the Invention However, in the conventional configuration, the hot water supplied into the extraction container during beverage extraction has a short residence time in the extraction container, and the hot water passes through the tea leaf raw material and the filter in a short time and is poured into the cup. It will be broken. Therefore, the extraction efficiency is poor, and the extracted beverage is often unsatisfactory in terms of concentration, flavor, etc.

This invention solves the conventional problems, and aims to increase the extraction efficiency by increasing the residence time of the hot water supplied in the extraction container during beverage extraction, and to provide a beverage with high concentration and good flavor. do.

Means for Solving the Problem In order to achieve this object, the tea brewing device of the automatic tea dispenser of the present invention has a mesh filter and the filter is inserted and disposed in a removable manner, and is reversed when replacing the tea confectionery. It consists of a plate, an arm disposed on the underside of the plate, a rubber gasket attached to the arm, and a funnel with an open top and two holes in the bottom. .

Function: With this configuration, when the tea leaf raw material discharged from the tea canister hopper is received on the filter and hot water is supplied, the plate supporting the filter will be able to open one of the two holes provided at the bottom of the funnel in the tea brewing state. Because the funnel is blocked by the seal, the hot water passes through the tea confectionery ingredients and the filter, and the extracted beverage does not immediately flow out of the funnel.
First, it stagnates at the bottom of the funnel, and the steam rising from there steams the raw material for tea confectionery.Then, the amount of beverage increases and reaches the filter.The extracted beverage that has passed through the filter mixes with the raw material of tea leaves, and is extracted again. As well as being carried out,
Hot water above the filter also passes through the filter at a slower rate, and is extracted over time. The liquid gradually flows out of the funnel through the hole that is not blocked by the seal. Also, when you want only hot water, the plate turns over and stops at a predetermined position, and the two holes at the bottom of the funnel are fully opened, and the hot water is poured directly from the hot water nozzle without going through the tea strainer filter containing the tea leaf ingredients. It is poured into a funnel and quickly supplied simultaneously through two holes provided at the bottom of the funnel.

EXAMPLE An example of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an automatic tea dispenser according to an embodiment of the present invention.

In FIG. 1, 7 is a tea dispenser. 8 is a tank for storing hot water, and a heater 9 is arranged on the bottom surface. 10 is a hot water supply pipe; 11 is a hot water supply valve that controls hot water supply;
12 is a hot water supply port provided at the tip of the hot water supply pipe 1o.

Numeral 13 is a tea leaf supply hopper for supplying new tea confectionery, and 14 is a tea leaf exchanging device which incorporates a geared motor 16.

16 is a tea brewing device located below the hot water supply port 12 and extracts a beverage using the tea confections supplied from the tea confection supply hopper 13 and hot water injected from the hot water supply port 12; This is a tea confectionery supply device that supplies tea to a tea strainer 16.

The tea brewing device will be explained below using the drawing of FIG.

In FIG. 2, reference numeral 18 is a cup-shaped funnel having an opening on the top surface and walls on the side and bottom surfaces, and the bottom surface has a step and two holes 19a and 19b are provided. Funnel 1
A stepped portion 2o along the circumferential direction is provided at a suitable location on the outer wall surface of the side wall 8, and two cutouts 1J are provided at appropriate locations on the stepped portion 2o. The funnel 18 is removably inserted and arranged by inserting it into a hole provided in the upper part of the cup-in-box so as to fit the two large and small convex parts provided so as to correspond to the two large and small notches, respectively. be done. 21 is a plate having a hole 22;
A mesh filter 23 is supported around the circumference by the peripheral surface. An arm 24 extending downward is provided on the lower surface of the plate 21.
A rubber gasket 26 is disposed at a suitable position on the arm 24, and is positioned to plug an upper hole 19a provided on the bottom surface of the funnel 18. 26
A filter holder is located above the plate 21 and is detachably fixed to the plate 21 along with the filter 23 by rotating in the circumferential direction.

The operation of the tea brewing device of the automatic tea dispenser constructed as described above will be explained below.

First, when the tea confectionery reaches the time to replace the tea depending on the time it has been left and the number of cups extracted, the geared motor 16 is energized and the tea leaf exchanging device 1
4, the tea confectionery that has become stale is discharged as the tea strainer 16 is turned over. After that, the tea strainer 16 reverses itself and returns to the predetermined position, and a certain amount of new tea leaves are transferred to the tea leaf supply hopper 13.
The tea leaves are extracted onto the filter 23 by the tea leaf supply device 17.

At the same time that the tea confectionery is received on the filter 23, electricity is applied to the hot water supply pulp 11, and hot water is supplied from the tank 8 to the tea leaves on the filter 23 through the hot water supply pipe 10 and the hot water supply port 12. When the supply of hot water is finished, the hot water passes through the tea confectionery filter 23 and is extracted as a beverage. In a conventional tea brewing device, the beverage is directly poured into a cup, but in the present invention, the beverage that flows out of the filter 23 does not directly flow out of the funnel 18, but is stored at the bottom of the funnel 18. This is because the gasket 25 provided on the arm 24 on the lower surface of the plate 21 is positioned to cover the upper surface of the hole 19a at the bottom of the funnel 18 to prevent the beverage from flowing out when the tea is brewed.
Beverage flows out of the funnel 18 only through the hole 19b. Therefore, the amount of beverage flowing out from the filter 23 into the funnel 18 is much larger than that flowing out from the hole 19b, and the beverage accumulates at the bottom of the funnel 18. The steam rising from the hot water surface of the beverage steams the sweets on the filter 23, and when the amount of beverage stored at the bottom of the funnel 18 gradually increases until the hot water surface touches the filter 23, -
The extracted beverage passes through the filter 23 and mixes with the tea confectionery again, and extraction is performed again. Further, above the filter 23, the speed at which the hot water passes through the tea leaves and the filter 23 slows down, and the beverage is extracted over a long period of time. Eventually, the beverage extracted in this way will pass through hole 1 at the bottom of the funnel.
It flows out of the funnel 18 through 9b.

When hot water is to be poured next time, the geared motor 16 is energized and the tea leaf exchanging device 14 rotates the plate 21 to a predetermined position. Accordingly, the pano-kin 26 provided on the arm on the lower surface of the plate 21 comes out of the closed state in contact with the hole 19a at the bottom of the funnel 18, and the hot water supply port 1
The hot water flowing out from 2 is directly poured into the funnel 18 without passing through the filter 23. This hot water flows through holes 19a and 19b as long as the water level is above hole 19a at the bottom of the funnel.
The water flows out of the funnel 18 from both locations at the same time. At this time, hot water supply port 1
Compared to the amount of hot water supplied to the funnel 18 from 2, the amount of hot water flowing out from the two holes 1.9a and 19b at the bottom of the funnel 18 is larger, so the hot water does not stay in the funnel 18 and is immediately poured into the cup. .

As described above, according to this embodiment, the plate 21 has a hole, the filter 23 has an outer circumferential step inserted into the hole of the plate 21, the filter 23 is pressed against the plate 21, and the filter 23 is pressed against the plate 21. A removably formed filter holder 26, an arm 24 fixed to the lower surface of the plate 21, a rubber-like gasket 26 provided at a suitable position on the arm 24, and a cup-shaped funnel 18 with an open top surface. At the time of beverage extraction, the gasket 26 provided on the arm 24 on the bottom surface of the seventh tray 21 is provided with two holes provided on the bottom surface of the funnel 18 and penetrating through the wall surface. Holes 19a, 19b
By blocking one of the funnels, the beverage is temporarily retained in the funnel 18, thereby increasing the extraction efficiency and making it possible to extract highly concentrated and flavorful tea.

Effects of the Invention As described above, the present invention includes a plate having a hole, a filter having an outer circumferential step inserted into the hole of the plate, and a filter that is pressed against the plate and is detachably attached to the plate. A filter holder, an arm fixed to the bottom surface of the plate, a rubber-like gasket provided on the arm at a suitable location, a cup-shaped funnel with an open top, and a wall surface that penetrates the stepped wall at the bottom of the funnel. By positioning the gasket so as to close one of the holes on the bottom of the funnel during beverage extraction, the residence time of the hot water supplied into the funnel during beverage extraction is reduced. prolongs the extraction efficiency and increases extraction efficiency.
Therefore, it is possible to supply a beverage with high concentration and good flavor. Additionally, since tea and hot water can be supplied using one hot water valve and hot water pipe, the number of parts can be reduced and the brewing section can be simplified. When providing hot water, the hot water is not poured forcefully directly into the cup from the hot water supply spout, but is poured into the cup through a funnel, so there is no risk of burns because the hot water does not scatter around.
