Hereinafter, a beverage cooking apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings. This beverage cooking apparatus is for cooking coffee and the like, and is mainly mounted on a cup-type mobile vending machine. 1 is a cutaway side view of the beverage cooking apparatus, and FIG. 2 is a plan view. As shown in both figures, this beverage cooking apparatus 1 is comprised from the mixing bowl 2 and the chute elevating mechanism 3 arrange | positioned above the mixing bowl 2. The mixing bowl 2 is composed of a bowl body 4 and a lid 5 to which the bowl body 4 is attached, and is supported in the vending machine at a portion of the lid 5. The lid 5 has a three-part structure of the lid body 6 and the base member 7 disposed above the lid body 6 (see FIG. 3).

The base member 7 has a stirring motor 8 attached to the center portion, an exhaust elbow 9 connected to a fan (not shown) and a hot water supply elbow 10 connected to a hot water tank (not shown). have. Moreover, the chute elevating mechanism 3 is attached with the raw material chute 11 which supplies the coffee powder raw material in the mixing bowl 2.

According to the sales instruction, the bowl main body 4 is supplied with a predetermined amount of powder raw material from a raw material container (not shown) via the raw material chute 11, and at the same time, a predetermined amount of hot water is supplied from the hot water tank via the hot water supply elbow 1. Then, the powder raw material and the hot water are stirred. Moreover, the hot water in the bowl main body 4 which generate | occur | produces at that time is exhausted to the exterior of the bowl main body 4 via the exhaust elbow 9 by a fan. In this way, when stirring of powder raw material and hot water is performed for predetermined time, stirring will stop and coffee will be supplied to the cup from the discharge port 12 of the bowl main body 4. On the other hand, when auto-rinsing the bowl main body 4, the hot water is filled to the position where the lower surface of the lid main body 6 is locked (refer FIG. 4), and stirring of a hot water is performed.

The bowl main body 4 accommodates the stirring mechanism 14 in the transparent resin container 13, and the resin container 13 is formed in the deformation lot type so that stirring may be performed efficiently. The upper end part of the resin container 13 is open | released widely, and is attached to the lid | cover 5 so that attachment and detachment are possible. The lower part of the bowl body 4 is constituted by a separate member having a discharge port 12, whereby the shaft end of the vertical shaft 22, which will be described later, is covered, and a mixture of powder raw material and hot water is led to the discharge port 12. do.

The stirring mechanism 14 includes a vertical shaft 22 connected to the stirring motor 8 via a coupling 21 at an upper end thereof, a rinse stirring blade 23 attached to the vertical shaft 22, and a cooking stirring blade 24. ) And the valve blade 25. The stirring blade 24 for cooking is arrange | positioned at the position embed | buried in the liquid mixture, and the valve blade 25 is arrange | positioned in the lowest part of the vertical shaft 22. As shown in FIG. The cooking stirring blade 24 and the valve blade 25 have a separate function of preventing the mixed liquid from flowing along with the rotation, and have a function of mixing (cooking) the powder raw material and the hot water with the rotation. In addition, the rinse stirring blade 23 is disposed at a position higher than the liquid level of the mixed liquid, and is usually idle, but when the resin container 13 is filled with rinse water, it is buried in rinse water and accompanied by rotation. The inner surface of the resin container 13 is washed.

The lid body 6 includes a raw material introduction port 31 facing the raw material chute 11, a hot water supply port 36 (see FIG. 2) connected to the hot water supply elbow 10, and an exhaust valve 9. The water heater outlet 32 which follows is formed. In addition, a hot water flow drop groove 33 is formed on the outer circumferential surface of the lid 6 and extends between the hot water flow drop groove 33 and the inner circumferential surface of the upper end of the resin container 13. An annular hot water passage 34 is formed. A plurality of small holes 34a are formed in the hot water passage 34 in the circumferential direction, and the hot water flows down the inner circumferential surface of the resin container 13 from the small holes 34a. Moreover, the hot water outlet 35 connected to the hot water supply port 36 is formed in the peripheral surface of the hot water heater outlet 32, and a hot water flows down also from this part so that the peripheral surface of the hot water heater outlet 32 may be wash | cleaned. In addition, the lower portion of the water heater outlet 32 is extended downward, and in this portion, the flow of the water heater is greatly bent so that the powder raw material together with the water heater can be prevented from being sucked into the water heater outlet 32. It is.

On the other hand, a second water heater outlet 41 is formed in the base member 7 so as to face the lower end of the raw material chute 11, and the second water heater outlet 41 is a coupling 21 of the stirring motor 8.

The second water heater outlet 41 is opened close to the raw material chute 11, and sucks (exhausts) air (heater) in the lower space of the raw material chute 11 which is moved upward as described later. In this case, the back board 11a of the raw material chute 11 also serves as a gate for opening and closing the second water heater outlet 41, and when the raw material chute 11 moves downward, the second water heater outlet 14 is closed. When it moves up, it opens. Specifically, since the hot water level reaches the hot water outlet 32 and the raw material inlet 31 in the rinse time shown in FIG. 4, the main exhaust passage 43 composed of the exhaust elbow 9 Hot water extraction on the introduction side 31 side becomes impossible. For this reason, the hot water dispenser on the side of the raw material introduction port 31 is performed by this sub-exhaust passage 42 which is connected to the second hot water dispenser outlet 41.

On the other hand, the exhaust elbow 9 is bent so that the fan side is inclined downward at an angle smaller than an angle of 90 degrees, and the water heater outlet 32 side is formed with a thin diameter, and the fan side is formed with a coarse diameter. Therefore, the water droplet which mixed the powder raw material which arises in the inclined downward part of the exhaust elbow 9 flows to the pan side. Moreover, the water droplet which arises in a bending part also flows to the boundary of a thick diameter part and a thin diameter part, and then flows to a pan side according to this boundary line (it becomes inclined downward). Thereby, the water droplet mixed with the powder raw material which generate | occur | produced on the inner surface of the exhaust elbow 9 is able to flow to a pan side actively, without staying in this part.

Next, the chute lift mechanism 3 will be described with reference to the side view of FIG. 5 and the front view of FIG. The chute elevating mechanism 3 raises the raw material chute 11 away from the raw material introduction port 31 at the time of rinsing, and prevents the tip of the wash chute 11 from being wet with hot water scattered at the time of rinsing. The chute lift mechanism 3 includes a holder 51 for holding the raw material chute 11, a support rod 52 for supporting the holder 51, a crank mechanism 53 for vertically moving the support rod 52, and And a gear motor 54 for operating the crank mechanism 53, and a frame 55 for supporting these support rods 52, the crank mechanism 53, and the gear motor 54.

The attachment member 56 which attaches the holder 51 to the support rod 52 is provided in the base of the holder 51, and the roller 57 protrudes from the lower side of the attachment member 56. The roller 57 is in rolling contact with the guide groove 55a of the frame 55. As the support rod 52 moves up and down, the holder 51 moves up and down along the guide groove 55a. Thereby, the raw material chute 11 hold | maintained by the holder 51 moves up and down between the downward movement position which the lower end face is facing the raw material introduction port 31, and the upward movement position which moves upward from the raw material introduction port 31. As shown in FIG.

The crank mechanism 53 includes a crank disc 58 directly connected to the gear motor 54, a crank arm 59 coupled to the crank disc 58, and a crank arm 59 rotatably attached to the middle portion. It is comprised by the rotation arm 60. The rotating arm 60 is rotatably attached to one end of the support shaft 61 while the support rod 52 is fixed to the other end thereof, and is supported by the crank arm 59 attached to the middle portion thereof. 61) It rotates in the up and down direction about the center. That is, the rotation arm 60 moves the support rod 52 up and down about the support shaft 61.

The lower end of the crank arm 59 is engaged with the pin 62 of the crank disc 58 via an elongated hole 59a formed in the crank arm 59. When the crank disc 58 starts mixing from the state shown in FIG. 5 or FIG. 1, initially, the pin 62 moves in the long hole 59a, but when it reaches near the top dead center, the pin 62 will be long. The crank arm 59 is pushed up against the upper end of the hole 59a (see Fig. 4). On the other hand, when the pin 62 passes through the top dead center, the crank arm 50 moves downward to the position contacting the stopper 63 with the weight on the rotation arm 60 side. Thereafter, the crank disc 58 rotates until the pin 62 reaches the bottom dead center.

The rotation of the crank disc 58 is controlled via a micro switch 64 provided adjacent to the crank disc 58. The switch stage of the micro switch 64 falls into two cam grooves 58a and 58a formed at two locations on the outer circumferential surface of the crank disc 58, respectively, and turns the micro switch 64 on and off. The two cam grooves 58a and 58a are arranged with the angles 180 degrees out of phase with each other. From the state shown in FIG. 5 or FIG. 1, the crank disc 58 starts rotation, and the pin 62 is similar to the top. When it reaches a point position, the switch end part falls to one cam groove 58a, the micro switch 64 turns on (or off), and the gear motor 54 stops (state of FIG. 4). Next, from the state of FIG. 4, when the crank groove 58 starts to rotate again and the pin 62 reaches | attains the bottom dead center position, a switch end falls to the other cam groove 58a, and the gear motor 54 stops. (State of FIG. 1). That is, as shown in Figs. 1 and 4, respectively, the state where the pin 62 reaches the top dead center position and stops corresponds to the upward movement position of the raw material chute 11, and reaches the bottom dead center position and stops. It corresponds to the downward movement position of the raw material chute 11.

Here, the selling operation (cooking operation) will be described with reference to FIG. 1, and the rinse (auto rinse) operation will be described with reference to FIG.

As shown in FIG. 1, the stirring motor 8 first starts to drive, and at the same time, hot water and powder raw materials are introduced into the bowl body 4, and the exhaust water operation of the hot water is started before and after each other. do. The hot water is supplied from the hot water passage 34 formed in an annular shape so as to wash the inner surface of the bowl body 4, and the hot water outlet 32 is washed from the hot water outlet 35. On the other hand, the powder raw material falls from the raw material chute 11 at the downward movement position via the raw material introduction port 31. In addition, exhaust of the water heater is performed by sucking outside air from the raw material introduction port 31 and evacuating it from the water heater outlet 32. Then, when a predetermined amount of hot water and powder raw material are supplied, and stirring of these mixed liquids is performed for a predetermined time, the stirring motor 8 stops, and the mixed liquid flows down automatically from the discharge port 12. Thus, the selling operation is repeated, but if it detects that the predetermined number of selling operations have been performed, or by the operator's switch operation, the rinse in the bowl main body 4 is periodically performed.

As shown in FIG. 4, when the apparatus shifts to the rinse motor, the stirring motor 8 starts driving, and at the same time, hot water is supplied into the bowl body 4, and the exhaust operation of the hot water heater is started. In addition, the raw material chute 11 is moved to the upward movement position by the chute elevating mechanism 3 prior to the supply of the hot water. In this case, the hot water is filled in the bowl body 4 up to the water level reaching the raw material inlet 31 or the hot water dispenser outlet 32, and the deep portion of the hot water is stirred by the rinse stirring blade 23 for rinsing. Rinse agitation is performed by the 24 and the valve blades 25. On the other hand, the hot water dispenser is filled (closed) with the hot water dispenser outlet 32, while the second hot water dispenser outlet 41 is opened with the upward movement of the chute 11, so that the raw material chute 11 The water heater is exhausted from the second water heater outlet 41 so that the water heater in the lower space, that is, the water inlet 31 is not erected toward the material chute 11.

The amount of the bath required for rinsing is defined by the opening time of the solenoid valve 15 provided on the outlet side of the bath tank shown in FIG. In this case, if the opening time of the solenoid valve 15 is uniformly set (stored in the controller 16) at the factory stage, the amount of hot water may be insufficient due to the fluctuation of the solenoid valve 15, or the hot water may overflow from the bowl body 4. There is. Therefore, the opening time (the amount of hot water) of the solenoid valve 15 in the control unit 16 is set based on the amount of hot water data at the time of cooking. That is, the amount of hot water for cooking is finely adjusted for each vending machine at the time of installation to affect the taste of the sales beverage. For this reason, the amount of water data at the time of cooking is sufficiently considered as a product of the solenoid valve 15, and the rinse bath based on this data is supplied with high precision in quantity.

As described above, according to the present embodiment, since the bowl main body 4 is provided with a stirring blade 23 for rinse in addition to the cooking stirring blade 24, the upper portion of the bath filled with the rinse is stirred with strong water force. It is possible to clean the inside of the bowl body 4 including the lower surface of the lid body 6 without staining. In addition, the attachment position of the stirring blade 24 for cooking does not need to consider rinse, and it can be considered that foam generation prevention and favorable stirring are considered. In addition, since the rinse stirring blade 23 is positioned above the liquid level of the mixed liquid at the time of cooking, the stirring blade 23 does not idle and affect the cooking.

In the above-described embodiment, since the rinse stirring blade 23 is attached to the vertical shaft 22 of the cooking stirring blade 24, the desired rinsing effect can be obtained as much as adding the rinse stirring blade 23. Can be. However, it is also possible to make the cooking stirring blade 24 serve as the rinse stirring blade 23 by moving the cooking stirring blade 24 upward at the time of rinse. For example, a spiral groove is formed on the surface of the vertical shaft 2 over the cooking position and the rinse position, and the stirring blade 24 for the cooking is held at the cooking position by the action of the spiral groove. The action causes the cooking stirring blade 24 to rise and remain in the rinse position.

In addition, in this embodiment, the cooking stirring blade and the rinse stirring blade are attached to the same rotating shaft and operated by the same stirring motor. However, the rinse stirring blade is fixed to the dedicated rotating shaft and connected to the stirring motor via a clutch. The rotary shaft and the stirring motor may be configured exclusively for rotating the stirring blade for rinse.

According to the beverage cooking apparatus of the present invention as described above, since the stirring blade for cooking is installed at a position higher than the cooking liquid level and lower than the liquid level for the rinsing liquid, the force of the water in the upper portion of the stirring vessel at the time of rinsing. The inside of the stirring vessel can be satisfactorily cleaned without staining without disturbing cooking of the beverage.
