BEST MODE FOR CARRYING OUT THE INVENTION (Embodiment 1)

 Hereinafter, the beverage extraction device according to the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side sectional view of the beverage brewing apparatus according to the first embodiment, FIG. 2 is a side sectional view showing a state where the upper cup 19 is inserted in FIG. 1, and FIG. FIG. 4 is a perspective view showing the filter and (b) the upper cup, FIG. 4 is an explanatory view showing the extraction state, and FIG. 5 is a block diagram of the load detection circuit.

In the beverage brewing apparatus 1, the housing 2 is made of metal or plastic on the right side of FIG. 1 and is made of metal or plastic. It is roughly divided. The machine room 3 houses a magnetron 9 as an electromagnetic wave generator, a radiation space 11 for reflecting and diffusing electromagnetic waves generated from the magnetron 9, and a magnet control circuit board 13. The electromagnetic shield 15 prevents electromagnetic wave components from leaking to the outside. At the lower part of the radiation space 11, an opening of an electromagnetic shield 15 is provided, and an electromagnetic radiation window 17 made of a non-conductive material such as plastic is attached. The magnetron 9 and the radiation space 11 are surrounded by an electromagnetic shield 15 except for the electromagnetic radiation window 17, and since this is a conventionally known technique, no particular description is given, and the cross section is shown. Not. The electromagnetic wave radiated from the magnetron 9 is radiated from the electromagnetic radiation window 17 toward the extraction chamber 5.

 An upper cup 19 is inserted into the extraction chamber 5 as a functional filter holding means. The upper cup 19 has a handle 19b at one end above the main body 19a, and a flange 19c at both upper ends. The upper cup 19 needs to have a shielding effect for a reason to be described later, and is preferably made of metal, but when it is formed of plastic or the like, a second layer is formed by layering a metal net on the inner surface or applying a metal plating. It is necessary to give a shield effect by the electromagnetic shield 19 e of this. The second electromagnetic shield 19 e surrounds the electromagnetic radiation window 17, which is the opening of the first electromagnetic shield 15, so that the electromagnetic wave components do not leak outside together with the first electromagnetic shield 15. Is shielded. A plurality of fine holes 19 f are formed in the bottom surface of the upper power switch 19, and the extracted liquid is dropped. Of course, a hole can also be made in the electromagnetic shield 19e, but the small hole keeps the shielding effect.

The front (right side in FIGS. 1 and 2) has a large opening 5a for receiving the upper cup 19 in the extraction chamber 5, and a door or the like may be provided if necessary, though not shown. Upper left and right (in Figs. 1 and 2 Is provided with a rail 5c with a groove 5b on the other side and on the near side. From the front of the extraction chamber 5 (the right side of the figure in Fig. 2), the groove 1b is inserted into the groove 5b. And slide it inward. The safety switch 21 is located above the extraction chamber 5 and to the left of FIGS. 1 and 2, and is turned on when the tip of the upper cup 19 contacts. The bottom of the extraction chamber 5 has an opening 5d.

 The front of the cup chamber 7 (the right side of Figs. 1 and 2) has an opening 7a for taking in and out the cup 23. Although not shown, a door or the like may be provided if necessary. On the bottom is a pedestal 25 on which an arbitrary force bar 23 is placed.Under this pedestal 25, a load sensor 27, which is a load detector, is placed, and this output is sent to the control circuit board 13 The load of an object connected and mounted on the pedestal 25 can be detected.

 A power switch button 29 and a start button 31 are arranged on the front of the housing 2 (right side in Figs. 1 and 2).

 In the upper cup 19, a filter mounting portion 19d slightly extends below the upper surface thereof, and a flange portion 33 integrally formed with the functional filter 35 is mounted thereon. The lower end 35 a of the functional filter 35 is closed by a method such as embossing or thermocompression bonding.

 The functional filter 35 may be any filter that does not transmit a low-temperature liquid but transmits a high-temperature liquid close to the boiling point of water. The first example of a functional filter is paper, made of pulp fiber, woven or non-woven fabric made of pulp fiber, cotton or fibers such as polyethylene or polypropylene, or plastic with pores. The base material is coated or impregnated with a heat-soluble material that dissolves at around a predetermined temperature so as to clog pores between the fibers or plastic or the like.

This heat-soluble material is edible, has little taste, At a temperature below a certain temperature, it is difficult for liquid to pass through, and at a temperature above a predetermined temperature, it is necessary to be able to pass through the liquid. For example, agar is suitable to meet this condition. Agar is a hot-water extract of viscous substances present in red seaweeds such as Amakusa, and the water is removed.The melting point is 80 ° C to 100 ° C, and the freezing point is 35 ° C to 45 ° C. It has a degree of hysteresis characteristic. Another heat-soluble material is at least one paste selected from carrageenan, furceleran, julangam, starch, and modified starch. In addition, although the use is limited, a saccharide-like candy-like substance may be used.

 The functional filter 35 may be a single layer in which fibers are impregnated with agar as described above, but the functional filter in which agar is applied or impregnated to cause clogging and a normal filtration filter are used. Laminated ones can be used, and various other deformations are possible.

 As a second example of a functional filter, hydrophobic heat fusible fibers such as polyester and polyolefin are used.For example, micropores with a diameter of approximately 70 to 250 μm that are approximately linear in the thickness direction by a wet method are used. A first nonwoven fabric layer formed on a nonwoven fabric having a nonwoven fabric and a second nonwoven fabric layer formed on a nonwoven fabric with hydrophobic heat-fusible fibers such as polypropylene and polyethylene are laminated, and the fine pores of the first nonwoven fabric layer form Even if a functional filter is used, which is made up of a layer that is adequately blocked by the fibers of the layer, this filter has no liquid permeability to water at room temperature, and the heated water reduces the surface tension of this filter. Good.

 In the present invention, in addition to the above, a material having a property of not allowing low-temperature liquid to permeate and permeating high-temperature liquid close to the boiling point of water can be used as a functional filter. Can be.

The operation is described below. First, press the power switch button 2 9 to attach the functional filter 3 5 to the collar 19 d of the upper cup 19 Place the collar 33 of the extractor, and put the extract material 37 (in this case, coffee powder) and extract solution 39 (in this case, water) into the functional filter 35 in predetermined amounts. Hold the handle 19 b and push the upper cup 19 from the opening 5 a of the housing 2 into the extraction chamber 5 so that the flange 19 c is inserted into the groove 5 b of the rail 5 c and then push it up. The actuator of the safety switch 21 is pushed by the cup 19 so that the beverage brewing device 1 can be energized. Here, when the start button 31 is pressed, the control circuit board 13 starts the oscillation of the magnetron 9, the electromagnetic wave is emitted from the radiation space 11 through the electromagnetic radiation window 17 into the upper cup 19, and the extraction liquid 39 is heated.

 When the power is turned on, the load sensor 27 starts detecting the load B shown in FIG. The load B is obtained by adding the weight of the extracted liquid 39 to the weight of the force 23 and the weight of the pedestal 25. When the power is turned on, weigh the weight of the power supply 23 and the pedestal 25 themselves. If the cup 23 is not placed on the pedestal 25, the dropped extract cannot be received, so that even if the start button 31 is pressed, the magnetron 9 can be prevented from oscillating.

 Extraction of the extraction material begins after water is injected. Although the degree of extraction is low during low temperatures, the extraction proceeds as the temperature of the extract 39 increases. On the other hand, as shown in Fig. 4, the temperature A of the extract 39 increases with time due to heating, but the drop of the extract 39 from the functional filter 35 causes the function of the functional filter 35 as shown in curve B. As a result, starting from a certain time C and passing the time D, most of the extraction material drops and the total weight applied to the load sensor 27 is saturated. For detection, it may be detected that B exceeds a predetermined amount, but in this case, the weight of the cup 23 must be constant and the amount of the extract 39 must be constant. This problem can be avoided by finding the saturation of. This operation will be described with reference to the block diagram of the load detection circuit in FIG.

In Figure 5, the output of load sensor 27 is an analog-to-digital converter. 4 Converted to a digital value by 1. The switch 43 is always at the midpoint 43a, and is alternately switched at predetermined time intervals between the contact 43b connected to the memory 45 and the contact 43c connected to the memory 47. . The contents of the memories 45 and 47 are updated when the switches are switched. The outputs of memories 45 and 47 are connected to the contacts of switches 49 and 51 as shown in the figure.Switches 49 and 51 are linked with switch 43 and are slightly less than switch 43. Each contact is switched from a to b with a delay and then from a to c after returning to a. If the output values of the switches 49 and 51 are input to the comparator 53, the change at every predetermined time can be read, so that the extraction has started or the change of the load B has been saturated after the extraction has been completed. When it is saturated, it is detected that the extraction is completed, and the operation of the magnetron 9 is stopped to end the heating. Although not shown, the end of extraction can be displayed by detecting this and sounding a buzzer or turning on a lamp. The load detection circuit in FIG. 5 is an example, and any method may be used as long as it can detect the change in load in FIG.

 As described above, according to this embodiment, the functional filter 35 is set in the upper cup 19, the extract material 37 and the extract 39 are put therein, and the upper cup 19 is placed in the housing 2. When installed, the power supply is ready.Pressing the start button 3 1 activates the magnetron 9 to start heating, and when extraction is completed, the change in the load sensor 27 can be detected and the operation of the magnetron 9 stops. As a result, the heating is finished as soon as the extraction is completed, and anyone can easily extract a beverage having a uniform taste without causing astringency or bitterness due to excessive heating.

 In addition, since the range of heating by the electromagnetic shields 15 and 19 e is limited, the magnetron 9 may be relatively small and power can be saved.

In addition, the force sensor that receives the extract and the load sensor, etc. Because of this, metal cups and cups that cannot be placed in an electromagnetic cooker can be used, eliminating the need to shield load sensors including metal parts.

 Here, an example of coffee extraction is given, but the invention is not limited to coffee but can be applied to green tea, black tea, herbal tea, herbs, and anything else.

 Further, even if there is no start switch, the operation of the magnetron 9 may be started when the safety switch 21 is turned on.

(Embodiment 2)

 In the first embodiment, a configuration is described in which a limited range is surrounded by an electromagnetic shield and heat is applied therein. Here, a configuration similar to a normal microwave oven, in which the entire housing is surrounded by an electromagnetic shield, will be described. Portions having the same functions as those in the respective drawings of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the schematic view of the beverage extraction device as viewed from the front in FIG. 6, the housing 55 has the same configuration as a normal microwave oven, and although not shown, the inner surface of the housing is entirely electromagnetically shielded. The front of the housing 55 can be locked with a door 57 provided with a perforated metal plate or the like on the inner surface of the glass for electromagnetic shielding as in a normal microwave oven. A filter mounting portion 59 on which the flange portion 33 of the functional filter 35 is mounted protrudes from the inner surface of the inside.

 At the bottom is a pedestal 61 on which an arbitrary force 23 is placed, and a load sensor 27 is mounted below the pedestal 61. Since the load sensor 27 has a metal part and is heated as it is by electromagnetic waves, the pedestal 61 is made conductive, or a conductive material is placed underneath, and they are installed in the housing. As part of the electromagnetic shield, keep the load sensor 27 from heating.

With this configuration, the operation is the same as that of the first embodiment, and the functional filter 3 is generated by an electromagnetic wave generated by a magnetron (not shown). The extraction solution 39 in 5 is heated, extracted from the extraction material 37 and dropped into the cup 23. The same function as that of the first embodiment can be achieved by stopping the magnet opening by detecting the saturation of the sum of the weights of the cups 23 and the extract 39 via the pedestal 61 or the increase in the weight.

 The operation unit may have the same configuration as a normal microwave oven, or may have the same operation function as that of the first embodiment.

 FIG. 7 is a perspective view showing a modified example in which the mounting position of the filter mounting portion in FIG. 6 is changed, in which the filter mounting portion 65 is arranged on the inner surface of the door 63. It is similar to that of FIG.

(Embodiment 3)

 FIG. 8 is a cross-sectional view of a beverage extraction device according to Embodiment 3 as viewed from the front. The difference from Fig. 1 is that the top filter 19 has three functional filters 2 in this example.

5 can be placed, and correspondingly, there are also three groups of openings 19 f below the force switch 19. Of course, three openings 5d below the first force-up chamber 5 are also provided. Also, three pedestals 25 and three load sensors 27 are provided.

 With this configuration, the electromagnetic wave radiated by the magnetron 9 circulates in the space surrounded by the first electromagnetic shield 15 and the second electromagnetic shield 19 e, and the three functional filters 35 The extraction material 37 is contained in the extraction material 37, and the extraction solution 39 is put therein. The extraction solution 39 is heated by the radiated electromagnetic waves, and can be extracted at once.

The extracted liquid dropped and dropped on the cups 23a, 23b, and 23c is detected by the load sensors 27a, 27b, and 27c as in the first embodiment. However, the end of extraction may vary due to variations in the amount of extract material, variations in the amount of extract 39, variations in the functional filter 35, etc. There is. Therefore, a detection circuit may be provided for each load sensor, and the operation of the magnetron 9 may be stopped after all the load sensors have detected the completion of extraction. In this case, it is convenient for work if the lamp for detecting the end is turned on in response to the power at which the extraction is completed early and the end of the extraction is detected, and even if the cup 23 is removed after the detection is completed. However, the extraction end state may be maintained so that it is reset when the operation of the magnet port stops after all extractions have been completed.

 Of course, the operation of the magnetron 9 may be started, for example, after all the functional filters have been installed, or it may be started when the power switch 19 is installed. Is also good. In addition, it is desirable to perform detailed considerations according to the intended use, such as detecting that the cups 23 corresponding to all the mounted functional filters have been mounted on the pedestal 25 and permitting the start. These can be implemented by a combination of a limit switch and a detection circuit of the load sensor 27.

 This embodiment may be implemented in combination with the structure of the second embodiment.

 As described above, in the present embodiment, it is possible to simultaneously extract and drop a plurality of forceps, and it is particularly suitable for use as a business in restaurants and the like.

 In the above embodiments, the details of the shape of the members, the number of the members, and the like may be arbitrarily set.

(Embodiment 4)

Hereinafter, a beverage extraction device according to Embodiment 4 of the present invention will be described with reference to the drawings. FIG. 9 is a side sectional view of a beverage brewing apparatus according to Embodiment 4 of the present invention, and FIG. 10 is a side sectional view showing a state where the upper cup 19 of FIG. 9 is inserted. Fig. 3 (a) and (b) for the functional filter and upper cup, Similarly, the explanatory diagram showing the extraction state is shown in FIG. 4, and the load detection circuit is similarly shown in FIG. It is to be noted that the same reference numerals denote parts having the same functions as those in the drawings of Embodiments 1, 2, and 3, and a description thereof will be omitted.

 The difference between the beverage extraction device 1 and the first embodiment shown in FIG. 1 is that a large opening 5 a in the front (the right side in FIGS. 9 and 10) for receiving the upper cup 19 in the extraction chamber 5 is provided. A door 8 is provided to cover both the front of the opening 7a of the cup chamber 7 and can be opened and closed by a hinge provided on one side in the vertical direction. That is what we did. Handle 8a is attached to door 8 for opening and closing. The safety switch 21 is turned on in the cup chamber 7 when the door 8 is closed. Door 8 may be provided with a light electromagnetic shield. This is because the first and second electromagnetic shields prevent the leakage of electromagnetic waves to a degree that does not cause any problem, but the fine holes 19 f, etc., or the joint between the first and second electromagnetic shields From the viewpoint, it is possible to apply a slight electromagnetic shield to the housing 2 from that point of view.

 The functional filters are exactly the same as those in the first to third embodiments.

The operation is described below. First, the brim section 3 3 of the functional filter 35 is placed on the filter mounting section 19 d of the upper cup 19, and the extract material 3 7 (in this case, coffee powder) and the extract 3 9 are placed on the functional filter 35. (In this case, water). Open the door 8, hold the handle 19b, and hold the upper cup 19 through the opening 5a of the housing 2 into the extraction chamber 5 so that the collar 19c is inserted into the groove 5b of the rail 5c. Press it in until When the cup 23 is placed on the pedestal 25 of the power chamber 7 and the door 8 is closed, the actuator of the safety switch 21 is pushed, and the beverage brewing device 1 can be energized. Press the power switch button 2 9 and then the start button 3 1 Then, the oscillation of the magnetron 9 is started by the control circuit board 13, an electromagnetic wave is emitted from the radiation space 11 through the electromagnetic radiation window 17 into the upper cup 19, and the extract 39 is heated. The start button may be omitted, and the oscillation of the magnetron 9 may be started when the safety switch 21 is turned on.

 However, in any case, if the operator forgets to place the cup 23 on the pedestal 25 and starts, the extraction liquid will be scattered in the cup chamber 7. It is desirable to configure the circuit so that the magnetron 9 starts oscillating after confirming.

 The following operation is the same as that of the first embodiment. When the extraction is completed, the door 8 is opened and the force 23 onto which the extraction liquid 39 has been dropped may be taken out.

 In the present embodiment, it is also possible to open the door 8 before the dropping of the extract is completed, and take safety measures against the hot extract dropped. As described above, the safety switch 21 is used to take safety measures such that the operation of the magnetron 9 is stopped by opening the door 8, but in the present embodiment, the door is further opened and the cup 23 is taken out. If so, the hot extract during extraction may fall into the power chamber 7 and cause burns. For this purpose, a staple device using an electromagnetic plunger (not shown) may be further added to the door 8 so that the lock is not released unless the end of the extraction via the weight sensor 27 is detected. Alternatively, a warning is displayed not to open the door 5 while the end of the extraction via the weight sensor 27 is not detected, or a message is displayed indicating that the end of the extraction may be opened by a lamp or sound when the end of the extraction is detected. You can.

 Further, the magnetron 9 may be configured to start operating when the safety switch 21 is turned on without the start switch 31.

If you open the door and take out the cup even though the extraction has not been completed, lock the door or prevent the hot extraction liquid during extraction from falling and causing burns. It is also possible to issue a ban that does not go wrong.

 As described above, according to this embodiment, the functional filter 35 is set in the upper cup 19, the extract material 37 and the extract 39 are put therein, and the upper cup 19 is placed in the extraction chamber 5. By closing the door 8, the safety switch is turned on and the power is ready.By pressing the start button 31 or closing the door 8, the magnetron 9 operates to start heating and finish the extraction. If the change can be detected from the load sensor 27 and the operation of the magnetron 9 stops, the heating ends with the end of extraction, and anyone can easily enjoy a beverage with a uniform taste without causing harshness or bitterness due to overheating. Can be extracted.

(Embodiment 5)

 FIG. 11 is a side sectional view of a beverage brewing apparatus according to Embodiment 5 of the present invention. The difference between FIG. 11 and FIG. 9 of Embodiment 4 is that there is no door at the front of the extraction chamber 5, and the door 10 exists only at the front of the opening 7a at the front of the extraction chamber 7. Is to be. Handle 10a is attached to door 10 for opening and closing flights. Then, in place of the safety switch 21, the safety switch 22 is mounted at a position where the safety switch 22 is turned on when the upper force 19 is completely inserted. The safety switch 22 allows the magnetron 9 to start oscillating when the start switch 31 is pressed, but the start switch 31 is omitted and the safety switch 22 is omitted. The magnetron 9 may start oscillating when 22 is turned on.

 However, in any case, if the user forgets to place the cup 23 on the pedestal 25 and starts the operation, the extraction liquid will be scattered in the cup chamber 7. It is desirable to configure the circuit so that the magnetron 9 starts oscillating after confirming the position.

The operation of this embodiment is the same as that of the fourth embodiment except for the function of the door 10. Yes, detailed description is omitted. Safety measures for opening the door 10 before the extraction is completed can be implemented in the same manner as in the fourth embodiment.

(Embodiment 6)

 In the sixth embodiment, although not shown, a door is provided in FIG. 8 of the third embodiment only in front of the blast chamber or in both the extraction chamber and the brew chamber. is there.

 Except for the door, the operation is the same as that of the third embodiment, and as in the fourth and fifth embodiments, if the door does not close and the oscillation of the magnet port does not start, the force You can take safety measures such as not being able to open the door unless it is completed.

 As described above, in the present embodiment, it is possible to simultaneously extract and drip a plurality of forceps, and it is also possible to consider safety aspects, and is particularly suitable for use as a business in restaurants and the like.

(Embodiment 7)

 Hereinafter, a beverage extraction device according to the seventh embodiment of the present invention will be described with reference to the drawings. FIG. 12 is a beverage extraction apparatus according to Embodiment 7 of the present invention, in which (a) is a plan view, (b) is a side sectional view, and FIG. 13 is a perspective view thereof.

In the beverage brewing device 71, the housing 733 is made of metal or plastic on the left side of FIG. 12 and is made of metal or plastic, and has a machine room 75, an extraction room 77, an extraction liquid receiving cup room 79, and a door 8. It is roughly divided into 1. The machine room 75 has a magnetron 83 as an electromagnetic wave generator and a non-conductive material such as plastic, and an electromagnetic radiation window 85 that emits electromagnetic waves generated from the magnetron 83. The first control circuit board, etc. The shield 87 prevents electromagnetic wave components from leaking to the outside. The electromagnetic shield 87 is provided so as to surround the outer periphery of the magnetron 83, the extraction chamber 77, and at least the extraction chamber part 89 of the door 81. The electromagnetic shield at the door 8 1 is electrically connected to the electromagnetic shield at the extraction chamber 5 by a hinge 9 1.

 It is preferable that at least the front of the door 8 1 is glass-coated so that the interior can be seen.The transparent part has an electromagnetic shielding effect by fine punching metal, etc. — Open and close by pivoting in direction B. When closed, lock mechanism (not shown)

10 Since these parts are conventionally known techniques, detailed descriptions are omitted. Then, the electromagnetic wave radiated from the magnetron 83 is radiated from the electromagnetic radiation window 85 to the extraction chamber 77.

 An extraction cup 93 is inserted into the extraction chamber 77. The extraction nip 93 is made of a non-conductive material such as polypropylene by vacuum molding or injection molding.

It is formed in a substantially cylindrical shape with 15 bottoms, and one or more small openings 95 are provided in the center of the bottom so that the extracted liquid can be dripped. Handles for carrying will be provided as necessary.

 In the extraction chamber 77, the front (left side of Fig. 12) and the upper part have an opening for taking in and out the extraction cup 93, which is closed by the door 81.

There are 20. In front of the electromagnetic radiation window 85, a guard 97 holding an extraction force 93 is formed of a non-conductive material, such as plastic, and an opening 99 is formed at the bottom of the extraction chamber 77. Is provided, which matches the opening 95 of the extraction cup 93. If the diameter of the opening 99 is too large, leakage of electromagnetic waves occurs, which is not preferable. The oscillation frequency of magnetron 83 is 2.

If it is 25 4 5 GHz, the wavelength will be about 12 O mm, and it is possible to make the diameter less than l Z l 6, that is, up to 7.5 mm. Alternatively, if the opening diameter is to be larger than this, it may be connected to an electromagnetic shield and a punching metal provided with a plurality of small holes, or a metal net connected to the electromagnetic shield may be attached.

 Although not shown here, a safety switch means for detecting that the extraction cup 93 is attached 5 is provided. This safety switch means detects that the extraction force is attached, and thereby controls whether or not the magnetron 83 is energized.Since the safety switch means includes a conductive part, it is electromagnetic Must be provided outside the shield 87, and the presence of the extraction cup 93 is mechanically transmitted to the safety switch means by a non-conductive lever, etc.

10

 The extraction liquid receiving chamber 79 at the bottom of the extraction chamber 77 has a pedestal 103 so that the extraction liquid receiving pipe 101 that receives the extracted liquid from the opening 99 can be arranged. A load sensor 105 serving as a load detector is disposed below the pedestal 103. This output is connected to the control circuit board of the machine room 75 內,

It is possible to detect the load of the extract and the load of the extract placed on 1505.

 A power switch button 107 and a start button 109 are arranged at appropriate places on the housing 73, in the upper part in this figure.

 In addition, around the extraction receiving cup chamber 7 9 and the extraction receiving chamber 7 for the door 8 1

A second electromagnetic shield 1 11 can also be applied to the front of the 209. This is to provide more safety when the opening 99 is large despite the shielding by the first electromagnetic shield 87 and a small amount of electromagnetic wave leaks from it. Electromagnetic shield of 8-7 does not need to be as strict as the shielding effect.

5 A functional filter 1 13 is placed on the extraction cup 93, and a functional filter 1 Radial ribs may be provided upward from the bottom surface so that the extraction force does not decrease due to the close contact of 13.

 The functional filter 113 may be formed by a press or the like according to the shape of the extraction cup 93, or may be formed by a method such as embossing or thermocompression bonding.

 The functional filter 1 13 may be any filter that does not transmit low-temperature liquid but transmits high-temperature liquid close to the boiling point of water, and has already been described in detail in the first embodiment. is there.

 The operation is described in the following with reference to FIG. First, press the power switch button 107, put the functional filter 113 on the extraction cup 93, extract material 115 (in this case, coffee powder) and extract liquid 117 (in this case, water) And put the extraction cups 93 into the extraction chamber 77.

 Here, when the start button 109 is pressed, the safety switch detects the extraction cup 93, the load sensor 105 detects the placement of the extraction receiving cup 101, and the safety switch of the door turns the door 8 on. If 1 is closed, the magnetron 83 starts oscillating by the control circuit, electromagnetic waves are radiated into the extraction cup 93 through the electromagnetic radiation window 85, and the extract 1 17 is heated. You. This is to prevent the extracted hot extract from falling into the extraction power chamber 79 and being scattered by starting without the extraction receptacle 101 being placed.

When the power is turned on, the load sensor 105 starts detecting the load B. The load B is the weight of the extraction receiving cup 101 and the pedestal 103 + the weight of the extracted liquid 1 17. When the power is turned on, the weight of the power supply 101 and the pedestal 103 is weighed. If the cup 101 is not placed on the pedestal 103, it will not be able to receive the extracted liquid, so that even if the start button 109 is pressed, the magnetron 83 will not oscillate. , In that case It would be nice to warn you of forgetting to power up by displaying characters.

-Extraction of the extraction material begins after water as the extraction liquid is injected, but the degree of extraction is low during low temperatures, but the extraction proceeds as the extraction liquid 117 becomes hot. On the other hand, although the temperature A of the extract 1 17 rises with time due to heating, the drop of the extract 1 17 from the functional filter 113 is due to the function of the functional filter 113 as shown by the curve B. Beginning at time C, the amount of dripping gradually increases, and after time D, most of the extractant drops and the total weight applied to the load sensor 105 saturates. For the detection, it may be detected that B exceeds a predetermined amount, but in that case, the weight of the hopper 101 must be constant and the amount of the extract 117 must be constant. This problem can be avoided by detecting the saturation of the curve B as described in the first embodiment.

 Next, it is necessary to take safety measures against opening the door 81 before the dripping of the extract is completed. Generally, in the case of a microwave oven, safety measures are taken to stop the operation of the magnetron by opening the door, but in the present embodiment, the door is further opened to take out the extraction receiving cup 101. In some cases, the hot extraction liquid during extraction may fall into the extraction receiving chamber 79 and be dangerous. For this purpose, a lock device may be further added to the door 81 so that the lock is not released while the weight sensor 105 does not detect the end of the extraction.

 Or, if the completion of extraction is notified by light, sound, etc., even if a lock is not provided, considerations such as displaying a message such as "Please do not open the door."

As described above, according to this embodiment, the functional filter 113 is set in the extraction cup 93, and the extraction material 115 and the extraction liquid 117 are put in the functional filter 113. The power supply can be prepared by attaching 3 to the extraction chamber 7 7 of the housing 7 3, and by pressing the start button 109, the magnetron 83 operates to add heat. The heat starts, and when the extraction is completed, it can be detected from the change in the load sensor 105, and the operation of the magnetron 83 stops, so that the heating ends with the end of the extraction, without causing harshness or bitterness due to overheating. Anyone can easily extract a beverage with a uniform taste.

 In addition, since the range heated by the first electromagnetic shield 87 is narrow and limited, the magnetron 83 may be relatively small and power can be saved.

 In addition, since the extraction liquid receiving cup and load sensor that receive the extraction liquid 1 17 are outside the first electromagnetic shield, metal cups and cups that cannot be placed in the electromagnetic cooker can be used. No need to shield load sensors including

 In addition, since the extraction liquid receiving portion is outside the first electromagnetic shield, the extracted liquid after the extraction is not further heated, and can be maintained at an appropriate temperature at which it can be immediately drunk.

 Further, when the first shield 87 alone cannot completely prevent the leakage of electromagnetic waves, the second electromagnetic shield can be added, and the safety to the human body can be increased.

 Here, an example of coffee extraction is given, but the invention is not limited to coffee but can be applied to green tea, black tea, herbal tea, herbs, and anything else.

(Embodiment 8)

FIG. 14 is a front view of a beverage extractor according to Embodiment 8 of the present invention, and FIG. 15 is a perspective view thereof. The difference from FIGS. 12 and 13 in Embodiment 7 described above is that the front part of the extraction chamber 79 of the door 81 a is not closed, and the view windows 8 1 b and 8 1 c is provided. Functionally, if this part is released, the extraction cuts can be made before the extraction is finished. This is to prevent the extract 101 from being taken out and overflowing the dropped extract, or to prevent the extract from catching hands and causing burns.

 In such a configuration, since it is meaningless to provide the second electromagnetic shield as in the seventh embodiment, it can be implemented when electromagnetic wave leakage from the first electromagnetic shield can be completely prevented. Other configurations and operations are the same as those in the seventh embodiment, and redundant description will be omitted.

(Embodiment 9)

 FIG. 16 is a drawing of a beverage extractor according to the ninth embodiment of the present invention, in which (a) is a side sectional view, (b) is a front view, and FIG. 17 is a flow chart for explaining the operation thereof. . The difference from Embodiments 7 and 8 is that three sets of extraction taps 9 3 a and 9 3 b are provided in the extraction chamber 7 7 a and the extract receiving chamber 7 9 a in the housing 73 a respectively. , 93 c and the extract receiving cups 101 a, 101 b, and 101 c. Of course, three sets of pedestals 103a, 103b, 103c and weight sensors 105a, 105b, 105c are also required corresponding to this. Although not shown, three sets of safety switches corresponding to the extraction force are also required. Other points are the same as those of the seventh and eighth embodiments, and detailed explanations are omitted.

Next, only operations different from those of the seventh embodiment will be described with reference to FIG. Turn on the power switch 107 in step S1. In step S2, all of the extraction cups 93a, 93b, 93c, or at least one of them is detected by the safety switch corresponding to the attached extraction cup. . In step S3, the start switch can be turned on after confirming that all of the extraction receiving cups corresponding to at least the extracted cups are mounted on the pedestal. When the start switch 109 is turned on in step S4, the door 81a is closed in step S5. Check if it is closed, and if it is closed, the oscillation of the magneto port starts in step S6. If it is not listed, it is kind to notify in some way. This is to prevent the extraction liquid from being scattered in the extraction reception chamber 79a without the extraction receiving cup.

 Then, in step S7, it is checked by the load sensors 105a to 105c whether all the extraction receiving cups 101a to 101c that have been extracted have been extracted. For example, in step S8, the operation of the magnetron 83 is stopped, and the extraction receiving force can be extracted in the same manner as in the seventh embodiment. In step S9, the power switch 107 is turned off, and all operations are completed. The flowchart of FIG. 17 can be applied to the third and sixth embodiments.

 As described above, according to the present embodiment, a plurality of extraction taps can be accommodated and a plurality of extractions can be simultaneously performed. At that time, if there is no extraction reception tap below the extraction tap, the operation cannot be started. If all of the extraction cups are not drip-extracted, the extraction liquid cannot be removed, or it may cause inconvenience or danger of inadvertently dirtying the device or causing burns by informing the user not to remove it. Can be prevented.

 Although the description has been made so that three sets can be extracted here, it goes without saying that two sets or four sets may be used.

(Embodiment 10)

 Hereinafter, description will be given based on the drawings. FIG. 18 is a front sectional view of a beverage extraction vending machine according to the tenth embodiment of the present invention, FIG. 19 is also a side sectional view thereof, and FIG. FIG. 21 is a cross-sectional view showing the same state of the coffee bean powder.

A bench stand for mounting each component in a housing (not shown) At the middle of the bench stage 201, at least the part of 201a indicated by the hatching is electromagnetically shielded. For this electromagnetic shield 301a, the hatched portion may be formed of metal, or a metal net or the like may be attached to a material other than metal, or a metal mesh, metal powder may be applied, or the like. A shield function may be provided, and the entire bench stage 1 other than the hatched portion may be formed of metal or a material having an electromagnetic shield function. Heating efficiency is increased by using as little metallic material as possible inside the electromagnetic shield 201a. A mouth filter 2003 in which a filter for extraction filtration is wound in a spiral shape is held on the side of the bench stage 201 by a shaft 203a, and is provided on one side surface of the bench stage 201. It is guided into the inside from the slit 201b, and is drawn out again from the slit 201c provided on the side surface on the opposite side, and is dropped into the trash can 205. The roll filter 203 passes over the lower die 207 for pressing the roll filter 203 provided in this path. On both sides of the lower mold 207, filter holders 209 for pressing the roll filter 203 when necessary are installed on the upstream and downstream sides, respectively, on both sides of the roll filter 203. There are four.

The upper pull roller 2 11 and the lower pull roller 2 13 constituting the filter moving means are, for example, the lower pull roller 2 13 is urged upward by a spring, and are pressed against each other so that the roll filter 2 is pressed. It is provided to draw 03. Even when the thickness of the coffee beans becomes thick due to the bias of the spring, the mouth filter 203 can be pulled. When the mouth filter 205 is pulled out, the catching roller 215 slightly protruding from the slit provided in the lower die 207 smoothes the movement of the roll filter 203. The hopper 2 17 and the press mold 2 19 are formed integrally. The press mold 219 forms a press means together with the lower mold 207. Hopper 2 1 7 The water in the water tank 22 1 is supplied from the upper opening 2 17 a through the valve 2 21 a. This portion is referred to as water supply means. In addition, the raw material (in this example, coffee bean flour) is supplied from the raw material container 2 23 through the shutter 2 23 a opened by the shirt driving source 2 25, and in all cases, the raw material is supplied from the lower opening 2 19 a. Drop 5. This part is collectively referred to as raw material supply means. Instead of providing the water tank 221, the valve 221 a may be directly connected to the water pipe.

 An extraction liquid drop port 201 d is provided below the electromagnetic shield 201 a, and a force receiver 229 for mounting the cup 227 is provided below the extraction liquid drop port 201 d. The cup receiver 229 is normally used for vending machines using cups, and it is assumed that a supply device for sequentially supplying a new force to the cup receiver 229 is attached. Detailed description is omitted.

 The dropper 200 d of the dropper 203 b formed by pressing the roll filter 203 to form a recess and the lower opening 2 19 a of the press mold 219 are located at 250 In the case of oscillation near 0 MHz, electromagnetic waves do not leak if the hole is about 7 mm. If this opening is about 10 to 15 millimeters and electromagnetic shielding is applied to the part of the bench stage 201 where the paper cup is located, if the power cup receiving part is never opened during power oscillation, There is no problem with a slightly larger hole.

 FIG. 19 is a view seen from the right side of FIG. 18. In FIG. 19, an opening 201 provided in a part of the electromagnetic shield 201 a is provided with a metal waveguide chamber. The output from magnetron 2 33 is led through 2 3 1. This part corresponds to high-frequency heating means.

The configuration is as described above. Next, the operation will be described. Pull out the roll filter 203, pull the end, and install it between the upper roller 2 11 1 and the lower roller 2 25 1 3. As shown in Fig. 20, lower the press mold 2 19, press the roll filter 203 between the lower mold 2 and press it, and press To form a drino, ° 203b. For the mouth filter 203, a non-woven fabric made of pulp fiber or plastic is used. At this time, one or both of the upstream side and the downstream side of the filter presser 209 are loosened so that the outlet filter 203 pulled by the press is released. Since there is a pulling roller upper 211 and a lower roller 213, the mouth filter 203 does not return.

 Then, the filter holder 209 descends, the press die 219 rises, and the filter holder 209 removes the roll filter so that the formed filter paper does not stick when the breath die 219 rises. Hold down. The cup 2 227 is supplied to the cup receiver 229, the shutter 223 a is opened by the shutter drive source 225, and the coffee bean powder 2 223 in the raw material container 223 as shown in Fig. 21 is opened. b is dropped to the recess of the dripper 203 b of the pressed outlet filter 203 with the specified amount, and then the valve 22 la is opened to release the water 22 1 b in the water tank 22 1 Inject a specified amount of water to prepare for extraction.

 Next, the magnetron 233 oscillates at a very high frequency by a control device (not shown), and the high frequency is supplied into the electromagnetic shield 201 a via the waveguide chamber 231, and the magnet filter 231 is driven by the dripping filter 209. Heat the water that has accumulated in par 203b. Extraction from coffee bean meal 2 2 3b starts little by little after the water 2 2 1b falls, and the extraction speeds up as the water is heated.

Generally, the "three-temperature extraction method" is advocated for making coffee and other delicious food. In other words, the three temperatures are low, medium and high temperatures. For example, gyokuro etc. should be extracted at a low temperature for a long time, but it is generally too long to use slightly hot water. With coffee, different flavors can be extracted at each temperature from the state of water until it becomes hot as in the case of so-called cold coffee. With the extraction device of this embodiment, starting from the state of water (low temperature), the medium temperature is reduced. So it can be extracted up to the boiling water (high temperature) It is exactly the right fit for this purpose, with a consistent, easy-to-use coffee.

 The end of the extraction may be specified by a timer, or the weight sensor may detect that the specified amount of the extract has been stored in the cup 227, and the optical sensor may stop the extract. May be detected, whereby the oscillation of the magnetron 233 is stopped. This is notified to the user by LED, sound, or synthesized speech, and the user is prompted to remove the cup 227. Although not shown, a safety device should be provided so that the door of the cup outlet cannot be opened during heating. .

 When extraction is completed, the filter presser 209 rises, and the upper and lower pulling rollers rotate, and a flat new part of the Lorenole filter 203 is placed immediately below the press mold 209. In addition, the used drippings and the residual coffee beans that have accumulated inside are flattened as much as possible by the auxiliary roller 215 together with the filter, and the trash can 20 is set by the pulling roller 2 11 and the lower roller 2 13. Move in the direction of 5. The slit 201c is considered to be wide at least at this time.

 As described above, according to the present embodiment, the water is not heated in advance, and the room temperature water is injected after the coffee bean powder is put into the dripper on which the filter is formed, and then high-frequency heating is performed. Since no electricity is required and the temperature is low, a favorable environment is obtained in which mold and bacteria are unlikely to grow. In addition, since the dripper is formed in a disposable filter, there is no need for subsequent cleaning or the like, and there is an effect that there is no waste of water and sanitary.

FIG. 22 is a diagram showing a roll filter according to the present embodiment. (a) is a side view, Fig. 22 (b) is a plan view, Figs. 22 (c) and (d) are side sectional views in a used state, and A-A in Fig. 22 (a) respectively. Cross section, BB shows B cross section. As shown in Fig. 22 (a), the roll filter 2 35 5 cuts the lower half of the roll material together to form a cut 23.5a, and welds the lower end and this cut-out part. The drippers 235b are integrated by pressing or bonding. The reason why the notch 235a is provided is to prevent the water filled in the part being extracted from oozing into the unused filter part due to the capillary phenomenon if this part is continued.

 After being installed in the beverage extraction vending machine, push the wedge-shaped guide 2337 open the notched upper part, and from there, hopper 235b for one piece of coffee beans powder and water from the hopper Inject. In order to mount this roll filter 235 on the beverage extraction vending machine of the embodiment 10 in FIG. 18, some modification of the device is required. First, the axis of this roll filter 235 must be vertical. The slits 201b and 201c through which the roll filter 235 passes must also be vertical. Then, a wedge-shaped guide 237 is added to the upstream side. Instead, the lower mold 207 is not required, and a simple platform is sufficient. Also, the press die 219 is not required, and the mechanism can be simplified since there is no need to press. With such a change, the beverage vending machine shown in Fig. 18 can be operated in the same way.

As described above, according to this embodiment, since the concave portion is formed in the roll filter in advance, there is no need to press, and the mechanism can be simplified. Water is not pre-heated.Normally high-temperature heating is also required, since normal temperature water is injected after placing coffee bean flour in a hopper pre-formed with a filter, followed by high frequency heating. Therefore, it is possible to obtain a suitable environment in which mold and bacteria are not easily propagated. In order to form the concave portion in the filter, the present invention is not limited to the above-described configuration, but may be any as long as a portion capable of accommodating a raw material and water can be formed as a dribber. (Embodiment 12)

 FIG. 23 is a diagram showing a roll filter 2339 containing coffee beans powder in the present embodiment. FIG. 23 (a) is a front view, FIG. 23 (b) is a sectional view of a main part, and FIG. FIG. 3 (c) is a perspective view seen from the lower surface. The roll filter 239 containing coffee bean flour, which is a filter means containing the raw material for extraction, is obtained by partially pressing a filter 241 using a nonwoven fabric made of pulp fiber or plastic and dribbling. Forming the powder 2411a, put the ground coffee grounds 2445 into it, layer the filter 2443 from above and combine them by pressing, welding, gluing, etc. into a roll.

 Filter 241 is for extraction, so a certain thickness and density is required, but filter 243 is for ground coffee beans 245, which is not scattered. When it is used by attaching it to the water, it is poured from the top, so it is preferable that the density is as rough and thin as possible so that water can be transmitted quickly.

In order to mount the coffee bean-containing roll filter 2 39 configured as described above on a beverage extraction vending machine as shown in Embodiment 10, the lower mold 2 07 is unnecessary, and a simple platform is sufficient. . Further, neither the press die 2 19 nor the raw material container 2 23 is required, and the configuration is greatly simplified. Instead, when the slit 201b moves the roll filter, it needs to be configured to be wider to pass the dripper 2411a. Since 9 is quite bulky, it is necessary to consider its space in the housing. By using the coffee bean meal-containing roll filter 23 9 and the beverage extraction vending machine of the present embodiment configured as described above, the water is formed in advance without heating in advance, and the coffee bean powder is contained therein. Room temperature water is injected into the dripper, and high-frequency heating is performed afterwards. Therefore, there is no need for standby power, and the low temperature provides a favorable environment in which mold and bacteria are not easily propagated.

(Embodiment 13)

 The feature of this embodiment is that the filter used in each of the above embodiments is changed to a functional filter having a special function. The functional filter has already been described in the first embodiment, but will be reprinted here.

 One method of making a functional filter is to apply or impregnate a filter material with a thickness of about 50 μm made of strong fibers such as pulp or plastic nonwoven fabric with a heat-soluble material. This heat-soluble material is edible, has little taste, is difficult to pass liquid at a temperature lower than a predetermined temperature, and must be able to pass liquid at a temperature higher than a predetermined temperature, for example. Agar is suitable for this condition.

 Agar is a hot-water extract of viscous substances present in red seaweeds such as Amakusa, and the moisture is removed.The melting point is 80 ° C to 100 ° C, and the freezing point is 35 ° C to 45 ° C. It has a degree of hysteresis characteristic. In addition, at least one kind of paste selected from carrageenan, furceleran, juran gum, starch, and modified starch is also effective as a heat-soluble material. Oplates also fall into this category. Although the use is limited, sugar-like candy-like substances may be used.

When agar is used, the production of a functional filter begins with powder agar or solid agar. Dissolve shaped agar etc. in hot water, make an agar solution of about 2 to 3%, boil and dissolve to make a solution. Corner agar and thread agar for general household use have a lot of impurities and are not very suitable for such applications. Before the melted product solidifies (solidification point is around 35 ° C), it is applied or impregnated to the filter substrate. Specifically, the agar solution is sprayed on the pulp fiber sheet by spraying. Alternatively, instead of spraying, it may be applied with a brush or the like, or the pulp fiber sheet may be immersed in the agar solution.

 After the application and impregnation are completed, the pulp fiber sheet is dried by air drying, heat drying or vacuum drying to remove moisture and to give an impregnated pulp fiber sheet. More preferably, the drying method is to dry the applied or impregnated agar solution at a gelling temperature or higher. Since this agar does not pass through the gelation process, it will be easily solubilized. In this functional filter, agar, which is a heat-soluble material, enters the gaps between the fibers and becomes solidified, causing clogging. This functional filter may be a single layer in which fibers are impregnated with agar as described above, but a functional filter in which clogging is caused by applying or impregnating agar with a normal filtration filter is laminated. Any other modifications are possible without any problem.

 Alternatively, a plastic sheet having pores coated or impregnated so that the pores are clogged with a heat-soluble material may be used.

As another example of a functional filter, hydrophobic heat-fusible fibers such as polyester and polyolefin are used.For example, micropores with a diameter of approximately 70 to 250 m that are approximately linear in the thickness direction by a wet method are used. A first non-woven fabric layer formed on a non-woven fabric having a non-woven fabric and a second non-woven fabric layer formed on a non-woven fabric with hydrophobic heat-fusible fibers such as polypropylene and polyethylene are laminated, and the fine pores of the first non-woven fabric layer are formed on the second non-woven fabric layer. The fiber in the layer is adequately closed, and this filter is not permeable to water at room temperature, and heated water takes advantage of the fact that the surface tension of this filter is reduced. Alternatively, a functional filter may be used.

 The filter of the present embodiment can be applied to the filters of Embodiments 10 to 12. That is, it can be applied to the mouth filter 200 3 of the embodiment 10, the roll filter 2 35 of the embodiment 11, and the roll filter 2 39 of the coffee bean flour of the embodiment 12. You. The filter 243 is a portion through which water at normal temperature passes, and cannot be used in this portion.

 The common feature of these various types of functional filters is that they hardly pass moisture at normal temperature, but they begin to pass moisture little by little as the temperature rises, and when the temperature reaches a certain temperature, they pass moisture rapidly Thus, there is an advantage that the extraction state can be made uniform by combining such a functional filter with high-frequency heating.

 We also found that filters using agar, in particular, reduce the bitterness and astringency unique to coffee. Initially, we thought that this phenomenon was due to the fact that the extraction conditions could be homogenized, but as a result of various experiments, even after the agar impregnated in the filter passed moisture due to the rise in temperature. The hypothesis was reached that it would remain around the filter fibers, absorbing the bitter and astringent components of coffee.

They also found that controlling the molecular weight of the agar to be impregnated could change the taste. In other words, it was also found that if various molecular weights of about 20,000 to 30,000, molecular weights of 100,000 or more, and intermediates were used in various combinations and impregnated, those with higher molecular weights would reduce bitterness and astringency. . This is because the higher molecular weight remains in the filter fiber and adsorbs bitter and astringent components from the extracted coffee. If it absorbs too much, it will have a simple taste, so it is important to match the molecular weight and its combination to the extraction conditions. From such experimental results, the above temporary I think that the theory is proved.

 As described above, according to the present embodiment, the use of the functional filter in the vending machine according to the tenth to thirteenth embodiments provides an effect that the extraction conditions can be made uniform. The use of agar as the heat-soluble material impregnated in the functional filter, and by optimizing the material, the effect of controlling the taste can be obtained.

 In the description of each of the above embodiments, the case of mainly extracting coffee is taken as an example. However, the present invention may be applied to extraction of not only coffee but also tea, green tea, herbs and the like.

 Each of the above embodiments can be implemented not only alone but also in combination with each other.

 Furthermore, the configurations, structures, and numerical values of the devices and filters mentioned as examples are merely examples, and it goes without saying that the devices and filters can be arbitrarily changed and used within the scope of the claims.

INDUSTRIAL APPLICABILITY As described above, the beverage extraction device of the present invention stores an extraction material and an extraction liquid in a functional filter that does not allow the extraction liquid to pass through at a low temperature and allows the extraction liquid to pass through at a high temperature. And heated by electromagnetic waves to detect the total weight of extract and drips that have passed through the functional filter due to the heating of the extract and dropped onto the nip, and have exceeded a certain value, or have saturated the weight increase. Stopping electromagnetic waves by detecting either of these factors prevents excessive extraction or insufficient extraction, and has the effect of allowing anyone to easily extract a certain taste.The substance that controls the function of this functional filter If agar is used, the bitterness and astringency of the extract can be controlled. The effect of cutting can also be added.

 In addition, if a configuration in which the area surrounded by the electromagnetic shield is reduced is used, a small magnetron can be used, and the amount of electricity used can be reduced.

 Furthermore, the beverage extraction vending machine of the present invention does not heat the water in advance, but pours the extraction material such as coffee bean powder into the filter-formed hopper, injects water at room temperature, and then performs high-frequency heating. Therefore, no standby power is required, no load is imposed on the environment, and the temperature is always low, so that a favorable environment is obtained in which bacteria do not easily proliferate as compared with conventional ones. In addition, since the dripper is formed in a roll-shaped disposable filter, there is no need for subsequent cleaning or the like, and there is an effect that there is no waste of water and sanitation.

 The use of a roll filter in which a dripper is formed in advance, or the use of a roll filter containing a raw material such as coffee bean powder, has the effect of further simplifying the configuration of the apparatus in addition to the above effects. can get.

 Furthermore, using a functional filter that changes the liquid permeability depending on the temperature as a filter, the extraction conditions can be made uniform, and using agar as the substance that controls the function of this functional filter can control the bitterness and astringency of the extract. If you can, you can add the effect.
