  Conventionally, as a raw material mixing device for beverage cooking, for example, a device disclosed in Patent Document 1 is known. This raw material mixing apparatus is applied to a tea machine that supplies tea-based beverages, and includes a mixing container having stirring blades therein. The mixing container is formed in a vertically long box shape, and a stirring blade is rotatably and detachably supported on a support shaft that horizontally protrudes forward from the lower portion of the rear wall. A circular opening slightly larger than the maximum diameter of the stirring blade is formed in the lower part of the front wall of the mixing vessel, and a cap having a ring-shaped seal corresponding to the edge of the opening closes the opening. It is attached detachably. In addition, a charging port for charging powdered tea and hot water is provided at the top of the mixing container, while a discharge port is provided at the bottom. Further, the stirring blade is provided with a magnet on the rear wall side of the mixing container, and this magnet is attracted to a magnet coupling provided on the back surface of the rear wall and rotatably connected to the motor. Therefore, the stirring blade is connected to the motor through the magnet coupling and is rotationally driven by this motor.

  In the raw material mixing apparatus configured as described above, at the time of providing a tea-based beverage, powdered tea and hot water are supplied from the respective charging ports to the mixing container, and the stirring blades are rotated by operating the motor. As a result, the powdered tea and hot water in the mixing container are agitated, whereby the powdered tea is dissolved in the hot water and a tea-based beverage is cooked. And this tea-type drink is sent outside via the discharge outlet of a mixing container.

  In such a raw material mixing apparatus, when tea-based beverages are repeatedly cooked, the stirring blades and the inner surface of the mixing container become dirty, and therefore it is preferable to wash them during maintenance. In this case, first, the cap is removed from the front wall of the mixing container, and the opening in the front wall is opened. Next, a finger is put into the mixing container through the opening, and the stirring blade is taken out. Then, the stirring blade is washed by round washing or the like.

After washing the stirring blade and the mixing container as described above, the cap and the stirring blade are attached in the reverse order of the above.

  As described above, in this raw material mixing apparatus, when washing the stirring blade and the mixing container, the cap must be removed from the front wall of the mixing container, and the stirring blade must be taken out from the mixing container. In this case, since the opening of the front wall is relatively small, it is complicated to remove and attach the stirring blades through the opening. In addition, it is difficult to put cleaning water and a brush into the small opening. Therefore, when it is attempted to clean the inner surface of the mixing container every corner, the cleaning is very complicated. Of course, by making the opening larger, it is possible to make it easier to remove and attach the stirring blades and to make it easier to put cleaning water and a brush into the mixing container. However, when the opening is enlarged, the sealing area by the cap is increased, so that the opening is likely to be insufficiently sealed and water leakage may occur.

  The present invention has been made in order to solve the above-described problems. During maintenance, the stirring blade can be easily cleaned by easily accessing the stirring blade, and the mixing container can also be cleaned easily and cleanly. It is an object of the present invention to provide a raw material mixing device for cooking beverages and a beverage cooking device provided with the raw material mixing device.

As shown in FIGS. 2 and 7, the low step portion 61 c and the high step portion 61 d are engaged with each of the low step portion 43 a and the high step portion 43 b of the receiving portion 41 in a state of being fitted snugly.

  As shown in FIG. 11, a front wall 62 c (second protruding wall) that is continuous with the left and right side walls 62 b and 62 b of the rectangular portion 62 and slightly protrudes upward is formed at the front end portion of the bottom wall 62 a of the rectangular portion 62. Is provided. Further, a rear wall 62d (first projecting wall) extending between the side walls 62b and 62b and projecting upward is provided at a position near the rear end of the bottom wall 62a. The rear wall 62d is formed to be shorter than the length between both side walls 62b and 62b, and is disposed so as to have a gap 62e (notch) between each side wall 62b.

  The semicircular portion 63 has a shape complementary to the inner surface of the semicircular accommodating portion 30 of the support concave portion 22. Further, the bottom wall 63a of the semicircular portion 63 is formed so as to incline forward and downward.

  On the other hand, the lid member 55 has the raw material chute 51 and the exhaust port 53 at the front part and the rear end part, respectively, and has a complementary shape with respect to the upper surface of the case member 54. Further, the lid member 55 is provided with a fitting allowance 71 that slightly drops downward along the peripheral edge of the lower surface excluding the raw material chute 51.

Further, the diameter of the lower end portion of the raw material chute 51 is formed to be slightly smaller than the hole 61 b of the case member 54. Further, behind the raw material chute 51 of the lid member 55, there are provided a front hanging wall 72a and a rear hanging wall 72b which are arranged at intervals in the front-rear direction and extend in the left-right direction and hang downward. The former 72a is located between the front wall 62c and the rear wall 62d of the case member 54, while the latter 72b is located behind the rear wall 62d.

  The lid member 55 is provided with a locking portion 73 for locking the steam discharger 16 to the support recess 22 of the holder 12. The locking portion 73 includes a flexible piece 73 a formed by cutting a planar shape into a U shape on the front side of the exhaust port 53, and a locking projection protruding from the front end portion of the flexible piece 73. It is comprised with the convex part 73b. The steam discharger 16 is locked to the support recess 22 by the locking protrusion 73b entering the locking groove 29b of the support recess 22 from below.

  In the steam discharger 16 configured as described above, as shown in FIG. 7, a steam passage 52 is defined that extends from the bottom wall 61 a of the case member 54 to the exhaust port 53 at the rear of the upper surface. Specifically, the steam in the mixing container 15 enters the steam discharger 16 from the gap between the hole 61 b of the bottom wall 61 a of the case member 54 and the raw material chute 51 of the lid member 55, and enters the case member 54. It flows through a horizontal passage portion 52a defined by the bottom wall 62a of the rectangular portion 62 and the lid member 55 and extending substantially horizontally in the front-rear direction, and is discharged from the exhaust port 53. And in the said horizontal channel | path part 52a, what is called for collecting steam and the fine powder of the powder raw material contained in it by the rear wall 62d of the case member 54, and the front hanging wall 72a and the rear hanging wall 72b of the cover member 55. A trap is configured.

  Next, a beverage providing operation in the beverage dispenser 1 will be described with reference to FIG. FIG. 12A shows operation timings of the coffee extraction device 2, the water supply device 3, the stirring motor 14 of the mixing bowl 7, and the raw material supply device 4. When a desired beverage is selected by the user of the beverage dispenser 1, it is determined by the control device 6 that there is a beverage provision command, and the coffee extraction device 2, the water supply device 3, the stirring motor 14 of the mixing bowl 7, and the raw material supply device 4 is controlled as follows. In addition, the operation | movement of the coffee extraction apparatus 2 and the water supply apparatus 3 in the following description means the operation | movement which supplies the extracted coffee and hot water to the mixing container 15 of the mixing bowl 7, respectively, These operation timings are fundamental. Are the same. Therefore, in the following description, the case where extracted coffee is used as a drinking liquid shall be demonstrated.

  First, after there is a beverage provision command, the coffee brewing apparatus 2 starts to operate (time t1). Thereby, the coffee extracted by the coffee extraction device 2 starts to flow into the receiving portion 41 of the mixing container 15 at a constant inflow speed through the coffee passage 28b and the inflow passage 45a of the mixing bowl 7. Further, almost simultaneously with the start of the operation of the coffee brewing apparatus 2, the stirring motor 14 of the mixing bowl 7 also starts to operate, and the stirring blade 13 starts to rotate. In this case, the coffee flowing into the receiving portion 41 via the inflow passage 45 a extends along the circumferential direction of the inner surface of the receiving portion 41 because the inflow passage 45 a extends obliquely with respect to the circumferential direction of the receiving portion 41. It is sent to the stirring unit 42 relatively slowly while generating a vortex.

  Thereafter, the raw material supply device 4 starts operating (time t2), and stops after a predetermined time (time t3). Thereby, a predetermined amount of powder raw material such as sugar or cream is supplied from the raw material inlet 43 to the receiving portion 41 of the mixing container 15 via the raw material chute 51 of the mixing bowl 7. And the coffee and powder raw material which were sent to the stirring part 42 from the receiving part 41 are stirred by the stirring blade 13, and a powder raw material melt | dissolves in coffee. In this manner, the coffee containing sugar and cream is discharged from the discharge passage 49a and supplied to the cup C while being cooked.

  Next, the coffee brewing device 2 is stopped (time t4), whereby the supply of coffee to the mixing container 15 is completed. Thereafter, the stirring motor 14 is also stopped (time t5), and the stirring blade 13 is stopped. This completes the provision of coffee with sugar and cream.

  When the beverage is cooked in the mixing container 15 as described above, the steam generated in the mixing container 15 is sucked by the fan (not shown) through the steam passage 52 of the steam discharger 16 and discharged to the outside. Is done. In this case, the steam discharged through the steam passage 52 flows so as to meander in the vertical direction in the horizontal passage portion 52a having a trap. At this time, when the steam hits the front hanging wall 72a, the trailing wall 72b, and the rear wall 62d and is condensed, the condensed water remains in the horizontal passage 52a. And said dew condensation water is removed by drying with a fan. In addition, the steam often contains fine powder of the powder raw material supplied to the mixing container 15, and the fine powder tends to stay in the horizontal passage 52a together with the dew condensation water. Thereby, it can suppress that said fine powder flows into the downstream of the horizontal channel | path part 52a, and can prevent clogging of the filter of the said fan, etc.

  Further, in the horizontal passage portion 52a, the condensed water remaining on the bottom wall 62a of the case member 54 flows from one of the upstream side and the downstream side to the other side through the gap 62e between the rear wall 62d and the side wall 62b. The bottom wall 62a can be easily spread. As a result, drying of the condensed water in the horizontal passage portion 52a is promoted, and the condensed water can be removed in a relatively short time. A notch may be formed in the middle of the rear wall 62d in the length direction together with or instead of the gap 62e. Further, since the front wall 62c is provided on the upstream side of the horizontal passage portion 52a, the condensed water remaining on the bottom wall 62a is blocked by the front wall 62c even if it flows to the upstream side, and the mixing container 15 does not flow.

  Further, as described above, after supplying the coffee containing sugar / cream to the cup C, the mixing bowl 7 may be rinsed. FIG. 12B shows the operation timing when rinsing is performed after the above-described coffee is provided. As shown in the figure, after the stirring motor 14 is stopped (time t5), the water supply device 3 and the stirring motor 14 are operated for a predetermined time (time t6 to t7). Thereby, the coffee adhering to the inner surface of the mixing container 15 and the surface of the stirring blade 13 can be washed with hot water. By performing such a rinsing operation immediately after the coffee is provided or before the next coffee is provided, the coffee is cooked with the clean mixing container 15 and the stirring blade 13 when the next coffee is provided. Can do.

  Next, a method for disassembling and assembling the mixing bowl 7 during maintenance will be described. When disassembling the mixing bowl 7, first, in the state shown in FIGS. 2 and 7, the steam discharger 16 is pulled forward while pushing down the locking projection 73 b of the locking part 73 of the steam discharger 16. Thereby, the steam discharger 16 is removed from the support recess 22 of the holder 12. Next, by depressing the engagement protrusion 44 at the rear upper end of the mixing container 15, the engagement with the upper locking claw 12 a on the holder 12 side is released, and the mixing container 16 is pulled forward. Thereby, the mixing container 15 is removed from the support wall 21 of the holder 12, and the stirring blade 13 is exposed to the outside (see FIG. 4). Next, the stirring blade 13 is also removed from the support wall 21 of the holder 12 by pulling the stirring blade 13 forward against the attractive force between the magnets 34 and 37.

  As described above, after the steam discharger 16, the mixing container 15 and the stirring blade 13 are removed in order, they are washed by round washing or the like. Further, when cleaning the steam discharger 16, the inside of the steam discharger 16 can be cleaned easily and cleanly by separating the case member 54 and the lid member 55.

  On the other hand, after washing the steam discharger 16, the mixing container 15 and the stirring blade 13, these are attached to the holder 12 in the reverse procedure of the above-described removal. In particular, when the mixing container 15 is attached to the holder 12, the lower end of the opening 46 of the stirring unit 42 is engaged with the lower locking claw 12 b of the holder 12, and this is used as a fulcrum to engage the rear end of the upper end. The joint protrusion 44 is pushed rearward along the guide rails 26a and 26a so as to pass below the guide rails 26a and 26a. Thereby, the mixing container 15 can be easily locked to the upper and lower locking claws 12a and 12b of the holder 12 at the upper and lower ends.

  As described above in detail, according to the present embodiment, during the maintenance, the steam discharger 16, the mixing container 15 and the stirring blade 13 can be removed from the holder 12 so that they can be washed out. The vessel 16, the mixing container 15 and the stirring blade 13 can be easily and cleanly washed. When the agitating blade 13 is removed, the entire agitating blade 13 is exposed to the outside, and when the agitating blade 13 is attached, an obstacle to the attachment is the periphery of the support wall 21 of the holder 12. Therefore, it is possible to easily remove and attach the stirring blade 13 as compared with the conventional case. Furthermore, since the opening 46 of the stirring unit 42 of the mixing container 15 is sufficient to accommodate the stirring blade 13, the sealing area of the opening 46 that is in close contact with the support wall 21 of the holder 12 is relatively small. As a result, the seal at the opening 46 can be sufficiently secured.

  In addition, the drinking liquid supplied to the receiving portion 41 of the mixing container 15 generates a vortex along the circumferential direction of the inner surface of the receiving portion 41, and the powder raw material is supplied thereto. Before mixing with the drinking liquid by the rotation of, the drinking liquid is also mixed with the drinking liquid by the swirl of the drinking liquid itself in the receiving portion 41. Thereby, a powder raw material can be melt | dissolved favorably in a drinking liquid, and a quality drink can be cooked.

  Furthermore, in the stirring unit 42, the drinking liquid and the powder raw material are stirred so that the shearing is repeated by the blade portion 33 of the rotating stirring blade 13 and the fins 48, so that the beverage is easily foamed, for example, cappuccino or the like. The forming beverage can be easily cooked.

  Further, the mixing bowl 7 has a structure in which the mixing container 15 cannot be removed unless the steam discharger 16 is removed from the holder 12 during maintenance. Therefore, when removing the mixing container 15 from the holder 12, there is a process of removing the steam discharger 16 from the holder 12 before that, so that the operator's degree of attention is likely to be higher than immediately after the start of maintenance. Misoperation by the operator can be reduced. Also, immediately after the start of maintenance, etc., when the operator erroneously supplies the drinking liquid to the mixing container 15 with the steam discharger 16 removed from the holder 12, the mixing container 15 is attached to the holder 12. As long as it is left, the surroundings of the mixing bowl 7 and the hands of the operator are not stained with the drinking liquid.

  In addition, since the supply of the powder raw material to the mixing container 15 is performed when a drinking liquid is present in the mixing container 15, it is possible to provide a high-quality beverage in which the powder raw material remains undissolved, and the mixing container 15 The inside can be kept hygienic. In addition, since the rotation of the stirring blade 13 is stopped after the supply of the drinking liquid to the mixing container 15, the rotation of the stirring blade 13 is continued until the end of the discharge of the beverage from the mixing container 15, so that the powder raw material can be used. The prepared beverage can be smoothly discharged from the mixing container 15 while being dissolved well.

  In addition, this invention can be implemented in various aspects, without being limited to the said embodiment described. For example, in the embodiment, the case where the present invention is applied to a beverage dispenser has been described. However, the present invention can be applied to various devices (for example, cup-type vending machines) for mixing beverages and powder raw materials and cooking beverages. Of course. The detailed configuration of the mixing bowl 7 shown in the embodiment is merely an example, and can be appropriately changed within the scope of the gist of the present invention.
