Description

DETAILED DESCRIPTION OF THE INVENTION B) Industrial Application Field The present invention relates to an apparatus for mixing powder raw materials and hot water to extract powder components.

(b) Prior art As such an extraction device, there is a technology disclosed in Japanese Patent Publication No. 56-35234. This is done by placing a piston through a filter at the bottom of the mixing chamber for hot water and powder raw materials,
As the piston rises, air is introduced into the mixing chamber for stirring, and as the piston descends, negative pressure is generated in the mixing chamber to perform extraction. Therefore, since the extraction device performs extraction by stirring and extruding hot water and powdered raw materials, it takes a relatively long time to supply the beverage, and the temperature of the beverage decreases due to the introduction of air.

(/-1 Problems to be Solved by the Invention As described above, the brewing device has a problem in that the temperature of the beverage is low.

In view of the above points, the present invention provides a beverage brewing device that can prevent the temperature of the beverage from decreasing.

(Means for Solving Problems -4) The present invention provides an extraction chamber into which powdered raw materials and hot water are introduced, a filter that is permeable to gas and liquid and forms the bottom of the extraction chamber, and an extraction chamber into which powdered raw materials and hot water are introduced. It consists of a steam generator that introduces indoor pressurized steam.

(E) Effect With the above configuration, when the extraction chamber is opened to the atmosphere and pressurized steam is introduced, the mixed liquid in the extraction chamber is stirred, and when pressurized steam is introduced with the extraction chamber sealed, the beverage is extracted through the filter. .

(f) Example FIG. 1 shows a side view of an extraction device according to the present invention.
Reference numeral (1) denotes an extraction chamber, which is composed of an upper chamber (3) into which the powdered raw materials and hot water are introduced and stirs the mixed liquid, and a lower chamber (5) where the beverage is extracted. The upper chamber (3) and the lower chamber (5) are connected through a communication port (4), and communication is controlled by a pulp device (7). A pin (Lz) is attached to the outer wall of the extraction chamber (1) and is locked to one end of the yoke (13), and the other end of the yoke (13) is pivoted to the shaft α4VC, and a spring haze is attached to the center of the yoke (13). The extraction chamber drive plate αη is in contact with the cam aυ via the cam follower αl, and is moved downward by rotation of the cam αυ at a predetermined angle, and the constant pressure device ( 16), and is equipped with a pin (4) at one end.The extraction chamber drive plate (17) is driven by a spring (not shown).
It is constantly biased upward. The lever Qυ is supported by a pin that moves up and down in the vertical direction as the extraction chamber drive plate αD moves. A pulp device (7) is connected to it, and a movable pin C!4)K is connected to the other end. The valve drive plate (c) is configured to come into contact with the cam (5) via the cam follower and move downward as the cam (2) rotates at a predetermined angle, and one end is connected to the adjustment nut ( ) is connected to the movable bin (2). This valve drive plate (c) is also constantly urged upward by a spring (not shown). With this configuration, when the valve drive plate (c) moves downward and the lever circle rotates clockwise about the pin (a), the force increases and the communication port (
4) is closed, and at this time, the roller (to) provided on the connecting shaft (c) slides on the guide rail (to), thereby guiding the movement in the vertical direction. The lower chamber (5) has a hole formed in its side and is connected to the steam generator (to) through a channel (8).

The steam generator (to) is composed of, for example, an electric boiler with a generated pressure gauge pressure of about 15. A pressure regulator Oυ and a solenoid valve (to) are connected to the tube (8). A filter (6) that forms the bottom of the extraction chamber (5) is provided at the upper opening of the beverage receiver hoa. A gasket (toward) is arranged in an annular manner around the opening of the beverage receiver V (33), and the lower end of the brewing chamber +1) is brought into close contact with the gasket by the urging force of the brewing chamber drive plate surface. I have come to do it.

Moreover, the bottom of the beverage receiver hr3s has an opening between pouring holes that are connected to a beverage chain. Beverage Chi-fu (Foundation)
is made of, for example, silicone rubber, which has excellent restorability, and opening and closing are controlled by the press buttons of the press plate 071. The suppression plate 0η is rotatably supported at one end, and rotated by being biased by the rotation of the cam.

(2) of cam α is the deceleration motor (4G drive shaft (41)
The cam (to) is attached to the driven shaft (c). The driven shaft (roller) is linked to the drive shaft (41) K by a set of pulleys (43) with a reduction ratio of 1:1 and a timing belt (c).
is the crank cam (?) attached to the drive shaft of the motor (4?).
(to) It is configured to move back and forth over the filter surface of the beverage tray 02 during busy periods to wipe away raw material scum after component extraction. In other words, the other end of the link 15G, which has a wiper frame attached to one end, is connected to the rotating link 6z by a pin (b) with the axis ω as a fulcrum by a connecting rod 5υ connected to the crank cam (b). The rotation of the motor (47) causes the link (
53 rotates, the link 6Q moves back and forth. In addition, the steam from the steam generator (to) passes through the tube (to) and heats the surface of the beverage tube (b), so that the extracted beverage does not cool down while passing through the beverage chain M. Therefore, the pressure regulator (31
A) and the solenoid valve (36A) are installed and swayed.

Figure 5, which explains the operation of the above configuration, shows the cam (1gJ
Fig. 6 shows the positional relationship between the cam (b) and the cam follower (4). At the standby position, cam C3! I is not acting on the suppression plate 13η and the beverage tube (to) is in an open state.

Also, the cam (II) urges the extraction chamber drive plate αη downward via the cam follower (19).Therefore, the yoke (13
is urged to rotate counterclockwise by the pressing force from the extraction chamber drive plate αn applied to the constant pressure device (161), and the lower end of the extraction chamber (1) is rotated as shown in FIG. It is in a state just before it comes into contact with the gasket (to).

In this standby state, the deceleration motor (4G
is driven, and each cam rotates a predetermined angle and stops when it reaches the stirring position. At this stirring position, the extraction chamber drive plate surface is cam αS.
The brewing chamber (l is the beverage tray 1-i) is pushed down further by the
03 K close contact. On the other hand, when the pulp drive plate (c) is urged downward via the cam follower (c) due to the rotation of the cam forehead, the lever (21) rotates clockwise about the bin (a) as a fulcrum. The pulp device (7) moves upward to close the communication port (4).

In this way, the cam (18) is driven by the deceleration motor (40).
When (27) rotates to the stirring position, the extraction chamber drive plate αη
The lever 01) is rotated clockwise by setting the amount of movement of the pulp driving plate (c) to be larger than the amount of movement of the extraction chamber driving plate αD. Further, at this time, the pulp device (7) is closed only to the extent that it does not come into contact with the rubber ring provided around the communication port (4). That is, the communication port (4) is in a half-open state where a gap 6υ is formed in the pulp device (closed by force).

Then, the rotation of the cam field causes the pressing plate C371 to rotate clockwise, thereby closing the beverage tube (b). The above state is the stirring state shown in Fig. 2, and after a predetermined time has elapsed since the generation of the extraction signal, the solenoid valve (to) is opened and the steam generator (
Pressurized steam is introduced into the extraction chamber (5) from the extraction chamber (5).

At the same time, the powder raw material and hot water are introduced into the receiving part (3A), and the powder raw material is introduced into the upper chamber (3)K while being mixed with the hot water. However, the pressurized steam introduced into the lower chamber (5) by opening the solenoid valve (36A) is
The gap is also blown through 1J to the upper chamber (3) which is open to the atmosphere. Therefore, the blowing up of the pressurized air prevents the mixed liquid in the upper chamber (3) from being introduced into the lower chamber (5) through the gap 6υ, and the mixed liquid stored in the upper chamber (3) is prevented from becoming vaporized. It is stirred by passing through it.

When the pressurized gas is steam, it has high thermal energy,
A drop in temperature of the beverage that occurs during stirring is prevented.

After performing such stirring for a predetermined time, a deceleration motor (4t
) is rotated by a predetermined angle and each cam is set to the introduction position.Since the shapes of the cam α second stirring position and the introduction position are set to have the same radius, the extraction chamber drive plate αη does not move and the extraction chamber ( 5) is in close contact with the beverage receiver. Also, since the shape of the introduction position of the cam (5) has a smaller radius than the shape of the stirring position, the pulp drive plate (c) moves upward, and the lever Qυ moves counterclockwise with the bottle (a) as a fulcrum. Rotate. Therefore, the pulping device (force moves downward and the communication port (4) opens wide).

Therefore, the mixed liquid in the upper chamber (3) is introduced into the lower chamber (5) through the communication port (4). At this time, the solenoid valve (to) closes with a slight delay after the stirring is completed. And since the cam field is not acting on the pressure plate, the beverage
The elastic restoring force pushes up and opens the suppression plate C371, allowing the coffee beverage to pass through. The states of the lever Qυ, pulp drive plate (c), pulp device (7), suppression plate C37) and cam follower (c) in this introduced state are shown by dotted lines in FIG.

When the movement of the mixed liquid from the upper chamber (3) to the lower chamber (5) is completed, the deceleration motor is rotated by a predetermined angle to set each cam at the extraction position. The radius of the extraction position of the cam a is also set equal to the radius of the stirring position, and the extraction chamber (5) is maintained in close contact with the beverage receptacle 02. Also, since the shape of the extraction position of the cam @ has a larger radius than the shape of the introduction position, the pulp drive plate (c) moves downward, and the lever Q
υ rotates clockwise around the pin (solstice) as a fulcrum. Therefore, the pulp device (7) moves upward and closes the communication port (4). Since the radius of the extraction position of the cam (5) is larger than the radius of the stirring position, the pulp device (7) at the extraction position closely contacts the rubber ring group and closes the communication port (4) without leaving a gap of 6υ. . Therefore, the space above the liquid level in the lower chamber (5) is sealed. This extraction state is the third
This is the state shown by the solid line in the figure, and when pressurized steam is introduced into the lower chamber (5) by opening the solenoid valve (to), the space above the liquid level in the lower chamber (5) is sealed. The mixture is forced out by pressurized steam and filtered through a filter (6), and the coffee liquid is introduced into the beverage tube (2) through the beverage receiver.

After the coffee liquid has been extracted, the solenoid valve (to) is stopped with a slight delay. Also, after the extraction is completed, the deceleration motor (4
0 by a predetermined angle to set each cam to the slag discharge position. Both cams (18@) have a smaller radius than the extraction position, so the extraction chamber drive plate (17) moves upwards due to the action of the spring mentioned above.Therefore, the lever Cυ also hardly rotates. Then, as the extraction chamber drive plate αη rises, the pressing force on the constant pressure device (Ie is removed, and the yoke αJ rotates clockwise.
Extraction chamber (the sword is lifted. Therefore the gasket (
The pressure contact between the extraction chamber (1) and the beverage tray (through) is released, and the brewing chamber Ql is opened so that the wiper (461) can pass over the surface of the filter (6) as shown in FIG. When the rise of the extraction chamber (1) is detected by a switch (not shown), a motor (47) K drive signal is given, and the power of the motor αη is transmitted to the link 6 via the connecting rod 611.
3 (5), and the wiper (3) removes the coffee grounds remaining on the filter (6).

When the completion of removing the coffee grounds is detected by a switch (not shown) that detects one rotation of the crank cam, the deceleration motor (41) is rotated by a predetermined angle to return each cam to its standby position, and the device is activated. The device is placed in a standby state as shown in FIG.

FIG. 7 shows another embodiment, in which the extraction chamber (
1) is not separated and stirring and extraction are performed in the same room. Components that perform the same functions as those in the previous embodiment are given the same reference numbers and their explanations will be omitted. The steam generator (to) is connected to the stirring tube συ and the extraction tube σω, and the extraction tube σ0 is connected to the inlet (751) provided at the top of the extraction chamber (1), and the stirring tube σ
J communicates with an inlet provided in the beverage receptacle 1c3a.

With this configuration, the powder raw material and hot water are taken out into the funnel σ gradient and introduced into the extraction chamber (1), and the solenoid valve σ3 is opened while the pulping device (7) is kept open to pass the pressurized steam through the filter (
6) into the extraction chamber (1). At this time, the beverage tube is closed and busy, and the pressurized steam is released from the communication port (
4) and the mixed liquid is stirred in the extraction chamber (1). Next, with the pulping device (7) closed, open the solenoid valve σ and open the beverage tube (b), the mixed liquid will be pushed out into pressurized steam and filtered through the filter (6) for extraction. will be carried out.

(G) Effects of the Invention According to the present invention, since the beverage is stirred and extracted by steam, the temperature of the beverage is prevented from decreasing.

By changing the introduction time of pressurized steam, desired stirring and extraction effects can be easily obtained.
