Therefore, when the beverage server 13 is placed on the upper surface of the heating plate 11, the step portion 109 is fitted in the inner edge frame 110, and the horizontal position of the beverage server 13 is positioned.

  The dripper 8 is made of a conductive synthetic resin as a conductive material, and as shown in FIG. 1 and the like, a bottom plate portion 111 formed in an elongated shape in the front-rear direction, and a substantially tapered shape from the periphery of the bottom plate portion 111 toward the upper side. The enlarged side plate portion 112 and the lateral grip portion 113 provided on the front portion of the upper edge of the side plate portion 112 are integrally provided. The grip 113 has a plate-like shape.

  As shown in FIG. 4 and the like, a plurality of rib portions 114 are formed on the inner periphery of the side plate portion 112 so as to project at intervals in the circumferential direction. By thus vertically disposing the plurality of rib portions 114, the outer periphery of the paper filter 10 partially contacts the plurality of rib portions 114 without being in close contact with the side plate portion 112.

  As shown in FIG. 1, the bottom plate 111 has a plurality of through holes 115 through which the extracted coffee liquid falls. The plurality of through holes 115 communicate with the central opening 16A of the lid body 16 with the dripper 8 mounted on the lid body 16.

  A lower end of the through hole 115 is formed inside a cylindrical portion 116 protruding downward from a lower surface of the bottom plate portion 111. In this way, by providing the tubular portion 116, the coffee liquid that drops through the through hole 115 drops downward from the lower end of the tubular portion 116 without wrapping around on the lower surface of the bottom plate portion 111.

  The conductive lever 21 is formed by bending a metal wire into a substantially U shape. More specifically, the conductive lever 21 connects the lower ends of the left and right arm portions 121, 121 in the vertical direction by a curved lateral portion 122, and bends the left and right arm portions 121, 121 in the center of the longitudinal direction. It is formed by providing 123. As a result, the conductive lever 21 has a substantially U-shape in a front view and a substantially V-shape in a side view. Then, at the standby position of the conductive lever 21 shown in FIG. 2, the upper portions of the arm portions 121, 121 are arranged in a substantially vertical vertical direction, and the lower portions of the arm portions 121, 121 are arranged obliquely forward. It

  Further, on the rear side of the eaves bottom plate 5K of the eaves portion 5, an opening portion 124 in which the conductive lever 21 is loosely inserted is provided. In the vicinity of the opening 124, the conductive lever 21 is pivotally attached to the case body 2 by a pivotal portion (not shown) in the left-right direction. The upper portions of the arm portions 121, 121 are inserted into the opening portion 124, and the upper ends of the arm portions 121, 121 are arranged inside the case body 2.

  In the mounted state of the dripper 8 shown in FIG. 1, the conductive lever 21 pushed by the dripper 8 rotates so that the lower side moves rearward, and the lateral portion 122 causes the side plate portion of the dripper 8 to move. It contacts the outer surface of 112. On the other hand, the arm 121 does not contact the dripper 8.

  Further, in the coffee maker 1, even when the power switch 43 is turned on, when the conductive lever 21 is in the standby position, the mill 17, the heater 12 as the server heating means, and the hot water feeding means 9 do not operate. Controlled as. On the other hand, when the conductive lever 21 is in the dripper mounting position, all electrically driven devices can be driven.

  One end of the conductive wire 23 is connected to the upper end of the conductive lever 21 by a screw (not shown) as a fixing means. The other end of the conductive wire 23 is connected to the upper surface of the bottom plate 22 by a screw 132 as a fixing means and a nut 133. Thus, the conducting wire 23 is built in the case body 2. In addition, the bottom plate 22 is widely formed so as to form the entire bottom surface of the case body 2. Further, leg portions 134 made of synthetic resin are provided on the front, rear, left and right of the bottom plate 22. The conductive wire 23 is flexible enough to make the conductive lever 21 movable.

  As shown in FIG. 2 and the like, a synthetic resin holder 135 is fitted over the upper portions of the left and right arm portions 121, 121. The holder 135 is fixed to the arms 121, 121 with screws. The conducting wire 23 is electrically connected to the arms 121, 121.

  Further, a seal member 136 made of silicone rubber, elastomer resin or the like is provided in the opening 124, and the left and right arm portions 121, 121 are inserted into the seal member 136. As a result, the left and right arms 121, 121 are inserted into the opening 124 in a watertight state, and the seal member 136 is elastically deformed to be swingable.

  A coil spring (not shown) is provided as a biasing means for biasing the conductive lever 21 to rotate toward the standby position. The holder 135 abuts on a stopper (not shown) on the case body 2 side to prevent the conductive lever 21 from further swinging, so that the conductive lever 21 is positioned at the standby position. .

  A contact detection switch 139 is provided on the case body 2. When the conductive lever 21 is in the standby position shown in FIG. 2, the operator 139S of the contact detection switch 139 comes into contact with the recess of the detection portion 135A of the holder 135, and the switch 139 is turned off. As a result, the contact detection switch 139 detects that the conductive lever 21 is in the standby position. On the other hand, when the conductive lever 21 is in the mounting position of the dripper 8 shown by the solid line in FIG. 1, the conductive lever 21 swings and the operator 139S is pushed by the convex portion of the detection portion 135A, The contact detection switch 139 is turned on. As a result, the contact detection switch 139 detects that the conductive lever 21 is at the mounting position. Thus, the conductive lever 21 detects the presence or absence of the dripper 8, that is, whether the beverage server 13 is placed on the heating plate 11 in a state where the dripper 8 is mounted on the lid 16. Also serves as a detection means.

  As described above, the conductive lever 21 swings between the standby position and the mounting position. At this time, since the seal member 136 is deformed, the watertightness of the opening portion 124 is secured, so that steam and dust are prevented from entering the inside of the case body 2 through the opening portion 124.

  Next, an example of how to use the coffee maker 1 will be described. First, the user turns on the power switch 43. Next, the user sets the paper filter 10 in the dripper 8 and attaches the dripper 8 to the lid 16 of the beverage server 13. In this case, the dripper 8 can be stably mounted on the beverage server 13 by loosely fitting the mounting part 107 at the lower part of the dripper 8 to the mounting receiving part 106 of the lid 16.

  Then, the user horizontally inserts the beverage server 13 equipped with the dripper 8 below the eaves portion 5 from the front side toward the rear side, and the beverage server 13 is placed on the heating plate 11 of the placing section 4A. Place on top. When the dripper 8 is set to the mounting position in this manner, the conductive lever 21 comes into contact with the dripper 8, and then the conductive lever 21 swings to the mounting position, which is detected by the switch 139. As a result, the mill 17, the heater 12, and the hot water feeding means 9 are in an operable state.

  In addition, the user operates the dial 39 to adjust the grain size to a desired value before charging the coffee beans into the mill 17. Then, an amount of water corresponding to the number of cups of coffee liquid to be extracted is put into the water storage section 6. Further, the mill lid 26 of the mill 17 is removed, and a predetermined amount of coffee beans is put into the hopper 25 from the charging port 24. At this stage, the shutter 91 is in a state of closing the drop opening 32, and the mill 17 and the inside of the dripper 8 are not in communication with each other.

  Then, when the user operates the switch 42, the following operations are sequentially performed. First, the shutter driving means 93 moves the shutter 91 in a direction of opening the drop port 32. As a result, the drop port 32 is opened, and the mill 17 communicates with the inside of the dripper 8. Next, the mill 17 is operated. When the mill motor 35 is rotationally driven to operate the mill 17, the coffee beans in the shooter portion 27 are sent by the mill screw 29 toward between the rotary blade 30 and the fixed blade 31, Ground between the rotary blade 30 and the fixed blade 31 is coffee powder (ground beans). Then, the coffee powder is dropped and supplied from the dropping port 32 into the paper filter 10 set in the dripper 8.

  Before the coffee powder is dropped and supplied from the dropping port 32, the motor 53 is driven and the nozzle body 51 is rotated. Then, the coffee powder drops on the rotating dispersion unit 102, and the coffee powder disperses and drops from the tip side and the periphery of the dispersion unit 102. Then, as the nozzle body 51 rotates, the dispersing means 101 also rotates, so that the coffee powder is evenly dispersed and stored in the paper filter 10. As a result, the coffee powder is not accumulated in a mountain shape in which the center of the paper filter 10 is high, but the coffee powder is accumulated in a state where the unevenness is relaxed.

  At the same time as the operation of the mill 17, the energization of the heating means 7 is started. As a result, the water in the water storage section 6 is heated to become hot water. Next, when it is detected that the mill 17 has finished grinding all the coffee beans, the mill 17 is stopped and the shutter driving means 93 moves the shutter 91 in the direction of closing the drop port 32. By detecting the current flowing through the mill motor 35, it is possible to determine whether or not the coffee beans have been ground. Further, by stopping the motor 53, the rotation of the nozzle body 51 is stopped. At this point, the water in the water storage section 6 is not yet hot water.

  Next, when it is detected by a temperature sensor (not shown) that the water in the water storage section 6 becomes hot water having a predetermined temperature (85 to 90 ° C.) suitable for extracting the coffee liquid, the heating is performed. The power supplied to the means 7 is stopped. Then, the hot water supply means 9 is activated to supply the hot water to the dripper 8 for the first time.

  Before the hot water supply means 9 is activated to supply hot water to the dripper 8, the motor 53 is driven again and the nozzle body 51 rotates at a constant speed. During the rotation of the nozzle body 51, the hot water in the water reservoir 6 is received by the hot water feeding means 9 from the hot water supply cylinder portion 74 through the liquid feeding path in the hot water supply portion 18 in the nozzle body 51. It is supplied to the space 70. The hot water supplied to the hot water receiving space 70 is discharged obliquely inward and downward from the discharge ports 52 of the plurality of nozzles 71, 71A, 71B provided in the rotating nozzle body 51, and inside the dripper 8. It is evenly sprinkled on the coffee grounds. Further, since the outlets 52, 52, 52 of the plurality of nozzles 71, 71A, 71B are arranged so as to be displaced in the radial direction of the nozzle body 51, the hot water is concentric with the coffee powder in the dripper 8. It is turned around. Therefore, in the central portion of the dripper 8, hot water is uniformly supplied in the radial direction. Then, after a lapse of a predetermined time, the hot water feeding means 9 is stopped and the first hot water feeding is completed. At the same time, by stopping the motor 53, the rotation of the nozzle body 51 is stopped. By this first hot water supply, the coffee powder in the paper filter 10 is steamed.

  When the predetermined steaming time has elapsed from the end of the first hot water feeding, the steaming step is completed. Then, after the steaming process is completed, the hot water feeding means 9 is activated to perform the second hot water feeding to the dripper 8. As described above, since the amount of water in the water storage unit 6 is an amount corresponding to the number of cups of coffee liquid to be extracted, if all the hot water in the water storage unit 6 is supplied to the dripper 8, A predetermined number of cups of coffee liquid will be obtained and the inside of the water reservoir 6 will be empty. Also, during the second hot water supply, the nozzle body 51 rotates, hot water is discharged from the discharge port 52, and the coffee powder in the dripper 8 is uniformly and concentrically wound around the coffee powder. The rotation speed of the nozzle body 51 is about 5 to 10 rotations / minute. As a result, the hot water can be evenly poured into the central portion of the coffee powder stored in the paper filter 10 set in the dripper 8, so that the coffee liquid can be well extracted and a delicious coffee liquid can be obtained. The coffee liquid extracted in the dripper 8 passes through the through hole 115 of the dripper 8 and the central opening 16A of the lid 16 of the beverage server 13 and is stored in the beverage server 13. At the same time as the second hot water supply, the energization of the heater 12 is started. As a result, the beverage server 13 placed on the heating plate 11 and the coffee liquid stored therein are kept warm. The heater 12 is energized for a predetermined time (for example, 30 minutes) from the start of energization. Then, after all the hot water in the water storage section 6 is sent to the dripper 8 and the hot water supply is completed, the motor 53 is stopped to stop the rotation of the nozzle body 51.

  By grinding the coffee beans with the rotary blade 30 and the fixed blade 31 of the mill 17, the coffee powder is charged. The coffee powder particles are charged to the same polarity. That is, the coffee ground particles are electrically repelled from each other. As a result, when the coffee powder falls from the drop port 32, the coffee powder easily spills from the gap 105 to the outside of the dripper 8.

  On the other hand, since the conductive lever 21 is in contact with the dripper 8 at the mounting position, the electric charge of the coffee powder dropped into the paper filter 10 is transferred from the paper filter 10 to the dripper 8 and the conductive lever 21. It moves to the bottom plate 22 through the lead wire 23 and is stored in this. The electric charges stored in the bottom plate 22 are gradually discharged to the outside. As a result, the coffee grounds stored in the paper filter 10 are not charged. Therefore, the coffee powder falling from the drop port 32 is not repelled by the coffee powder stored in the paper filter 10. Therefore, it is possible to make it difficult for the coffee powder to leak from the dripper 8. Note that the paper, which is the material of the paper filter 10, can be regarded as a conductive material because it can slightly conduct electricity. Therefore, the electric charge of the coffee powder can be released from the paper filter 10 to the conductive lever 21 via the dripper 8.

  Since the coffee powder particles that are falling are still charged, they fall while spreading. However, as described above, the falling coffee powder and the coffee powder stored in the paper filter 10 do not repel each other. That is, the only electrical element that spreads the falling coffee powder is the electric charge of the falling coffee powder itself. Therefore, since there is no repulsive force from below, the spread of coffee grounds during falling can be suppressed. Therefore, if the distance of the gap 105 is appropriate, the coffee powder that spreads and falls can be sufficiently received by the paper filter 10, so that the coffee powder can be less likely to leak from the dripper 8.

  On the other hand, the rotary blade 30 and the fixed blade 31 or the members around the rotary blade 30 that come into contact with the coffee beans are charged with the opposite polarity to the coffee powder. However, by exchanging charges with surrounding objects, it returns to electrical neutrality in the long term.

  As described above, in this embodiment, the case body 2 as the main body, the mill 17 provided in the case body 2, and the dripper as the extraction tool arranged below the drop opening 32 that is the discharge outlet of the coffee powder of the mill 17 are provided. 8 and a hot water supply unit 18 serving as a nozzle body for supplying hot water to the dripper 8, in the coffee maker 1, the drop port 32 is located above the central portion of the dripper 8, The hot water supply unit 18 has an annular nozzle body 51 that is rotatably provided around the drop port 32, and a discharge port 52 that is provided below the nozzle body 51. Since it has a motor 53 as an electric motor for moving the coffee, the hot water discharged from the discharge port 52 is evenly spun in the dripper 8 to satisfactorily extract coffee, It can be brewed the coffee has to taste.

  Further, since the outlet 52 is inclined in the direction of the rotation center S so that the hot water falls to the central part of the dripper 8, even in the coffee maker 1 provided with the mill 17, By sprinkling hot water around the center of the dripper 8, the coffee can be better extracted and delicious coffee can be brewed.

  Further, it has a guide ring 75 which can be attached to and detached from the case body 2 which is the main body, and the guide ring 75 allows the nozzle body 51 to be mounted on the case body 2 and guided by the guide ring 75 to guide the nozzle. Since the main body 51 is configured to rotate, not only the nozzle main body 51 can be easily removed for maintenance, but also the nozzle main body 51 can be easily guided.

  Further, since the coffee powder dispersing means 101 is provided below the discharge port 32, which is the discharge port, the coffee powder is evenly stored in the dripper 8 so as not to be piled up. You can brew better coffee with better extraction.

  Furthermore, since the dispersion means 101 is provided below the nozzle body 51 and is configured to be rotatable together with the nozzle body 51, by being configured to be rotatable together with the nozzle body 51, You can brew better coffee and brew good coffee.

  The effects of the embodiment will be described below. Since the driven gear 67 is integrally formed by providing a plurality of tooth portions 66 on the outer circumference of the upper peripheral wall portion 64 which is the peripheral wall portion of the nozzle body 51, the driven gear 67 meshes with the drive gear 58 with a simplified structure. A gear 67 can be provided. Further, the nozzle main body 51 includes an annular bottom plate portion 61 that is obliquely installed so that one side sandwiching the center S is slightly lower than the other side, and a plurality of discharge ports 52 are provided on one side. Since it is arranged within a range of 90 ° with respect to the center of the nozzle body 51, even if the amount of hot water in the hot water receiving space 70 of the nozzle body 51 becomes small, the nozzle 71, due to the inclination of the bottom plate portion 61, The hot water gathers at 71A and 71B, whereby the hot water in the nozzle body 51 can be poured from the discharge port 52 without leaving. Further, the ejection openings 52, 52, 52 of the plurality of nozzles 71, 71A, 71B are arranged at positions different in distance from the center S and are obliquely installed at the same angle with respect to the rotation center S. Since the hot water discharged from the plurality of nozzles 71, 71A, 71B falls concentrically from the center S of the dripper 8 to different positions while the nozzle body 51 is rotating, the hot water is uniformly supplied to the dripper 8. can do. Further, the upper portion of the hot water receiving space 70 of the nozzle body 51 is opened, and hot water is supplied from the hot water supply cylinder portion 74 to the hot water receiving space 70, so that the hot water supply means 9 is connected to the discharge port 52 of the nozzle 71. Since the pressure is not directly applied, the hot water can be supplied to the dripper 8 so that the hot water is gently poured from the discharge port 52.

  The guide ring 75 has a curved upper end 77W in which the upper end of the peripheral wall 77 is curved, and the insertion flange 63 slides on the curved upper end 77W and the peripheral wall 77 slides. The outer peripheral surface of the lower peripheral wall portion 62 of the nozzle body 51 partially slides on the inner peripheral surface 77N that is the receiving portion, so that the rotating nozzle body 51 can be stably supported. Further, a mounting means for mounting the nozzle main body 51 on the mounting base 54 constituting the main body by the guide ring 75 is provided, and the mounting means rotates the guide ring 75 with respect to the mounting base 54. Since it is a means for attaching and detaching, the attaching and detaching work of the guide ring 75 becomes easy. Furthermore, since the operation recess 81 for arranging the operation lever 82 is provided in the mounting base 54 constituting the main body and the projection 83 for engagement is provided in the operation recess 81, the guide ring 75 can be removed accidentally. It can be prevented.

  Further, in the coffee maker 1 having a case body 2 as a body, a mill 17 attached to the case body 2, a dripper 8 as an extractor for receiving beans ground by the mill 17 and a paper filter 10, A conductive lever 21 which is a contact member made of a conductive material is provided in the case body 2, the dripper 8 is made of a conductive material, and the dripper 8 contacts the conductive lever 21 and temporarily charges the case body 2. Is provided with a bottom plate 22 as a power storage member that is electrically connected to the conductive lever 21. When the ground coffee ground and charged by the mill 17 contacts the paper filter 10. , The electric charge of the coffee powder is transferred from the paper filter 10 to the dripper 8 and the front. After moving to the bottom plate 22 via a conductive lever 21 is naturally discharged from the bottom plate 22 to the outside. As a result, the coffee powders can be made less likely to repel each other, and the falling coffee powders can be made less likely to leak from the dripper 8. Further, since the dripper 8 is made of a conductive synthetic resin, the dripper 8 having a shape suitable for extraction can be easily formed. In this case, for example, the rib portion 114 is formed inside the dripper 8, and for structural reasons, in the case of metal, it is difficult to manufacture by pressing or casting, and the cost becomes high. On the other hand, the dripper 8 having a shape suitable for extraction can be manufactured at low cost by resin molding. Further, the conductive lever 21 serving as a contact member also serves as a detection means for detecting the presence or absence of the dripper 8, and the coffee maker 1 can be normally operated while suppressing an increase in the number of parts.

  Further, a ring-shaped step portion 109 having a smaller diameter than the bottom plate portion 108 is bulged downward on the bottom plate portion 108 of the container body 14, and the ring-shaped inner edge frame 110 in which the step portion 109 is loosely fitted is formed. Since the stepped portion 109 of the container body 14 is formed to project on the upper surface of the heater 12 and is surrounded by the inner edge frame 110 on the heater 12 side in a mounted state, the beverage server 13 is mounted on the heating plate 11 in a positioned state. The dripper 8 mounted on the beverage server 13 can be reliably detected by the conductive lever 21. Further, since the gap 105 is provided between the dripper 8 and the eaves bottom plate 5K of the eaves portion 5, it is possible to see how the coffee powder in the dripper 8 is poured and swelled. Further, when the conductive lever 21 is in the standby position, the mill 17, the heater 12 as the server heating means, and the hot water feeding means 9 do not operate, so that the erroneous operation can be prevented without mounting the dripper 8 and the beverage server 13. it can. Further, since the conductive lever 21 is formed by bending a metal round bar into a substantially U shape, the conductive lever 21 has a simple structure and can be manufactured at low cost.

  Furthermore, the dripper 8 can be stably mounted on the beverage server 13 by loosely fitting the mounting part 107 at the lower part of the dripper 8 to the mounting receiving part 106 of the lid 16. Moreover, since the bottom plate 22 is made of stainless steel having a specific gravity larger than that of the synthetic resin forming the case body 2, the bottom plate 22 serves as a weight, so that the coffee maker 1 can be stably installed. Further, since the tubular portion 116 is provided so as to project downward from the lower surface of the bottom plate portion 111, and the through hole 115 is bored in the tubular portion 116, the coffee liquid that drops through the through hole 115 by the tubular portion 116 is It is possible to allow the bottom portion of the bottom plate portion 111 to fall downward from the lower end of the tubular portion 116 without wrapping around.

  Further, since the seal member 136 is provided in the opening 124 provided in the eaves bottom plate 5K of the eaves 5, the conductive lever 21 is movably provided in the opening 124, and the inside of the case main body 2 is provided. The sealing member 136 can prevent the intrusion of steam and dust. Further, since the gap 105 is provided between the dripper 8 and the eaves portion 5 in the mounted state of the dripper 8, the beverage server 13 can be easily put in and taken out from the heating plate 11. Further, the conductive lever 21 as a contact member is made of a metal wire rod having a circular cross section and is movably provided with respect to the case main body 2 as a main body, so that the conductive lever 21 can be formed in a thin shape. As a result, the opening 124, which is a gap formed in the case body 2 for providing the conductive lever 21, is narrowed, so that even if the seal member 136 is not provided, the dripper 8 can move from the inside of the case body 2 to the inside of the case body 2. The amount of steam entering can be reduced.

For example, in the embodiment, the driven gear is provided in the nozzle body, and the drive gear that meshes with the driven gear is rotated by the electric motor to rotate the nozzle body. The rotation of the electric motor may be transmitted to the nozzle body by using a belt or the like. Further, for mounting the guide ring, another rotary mounting structure such as a screw or a bayonet may be used, or a mounting structure other than the rotary mounting structure may be used. Further, in the above embodiment, the dripper is placed on the beverage server, but the dripper may be attached to the main body, for example, the dripper is housed in a storage case, and one side in the left-right direction of the storage case is pivoted in the vertical direction. The storage case may be rotatably attached to the main body, and may be provided so as to be retractable from the main body by rotating the storage case together with the dripper.
