Therefore, the hot water and cold water supplied to the mixing ball 36 are diffused and poured out on the stirring blade body 33 in the radial direction of the stirring blade body 33, so that the hot water and cold water are easily scattered over a wide area inside the mixing ball 36. In addition, it is possible to reduce remaining beverage ingredients and foam on the inner surface of the mixing ball 36. If the diameter of the stirring blade body 33 is smaller than 80%, even if hot water or cold water is poured onto the stirring blade body 33, the hot water or cold water is less likely to be scattered over a wide area inside the mixing ball 36.

  In addition, the timing of rotation of a stirring blade body, supply of a drink raw material, and supply of hot water or cold water is arbitrarily set according to a drink kind.

  Then, after a predetermined time after the stirring and mixing of the beverage in the mixing ball 36 is completed, the stirring motor 99 is stopped, and the rotation of the stirring blade body 33 is stopped, so that the beverage in the mixing ball 36 is transferred from the outlet 42 to the funnel. The beverage is poured into the cup placed on the cup table 27 from the spout 75 of the funnel 73.

  Further, during the beverage dispensing operation, the exhaust fan 137 is rotated by the exhaust motor 136 of the exhaust unit 26 to exhaust the inside of the mixing ball 36, and the steam and moisture when hot water is supplied into the mixing ball 36 is the beverage ingredient. Reduces heading to supply unit 24. The flow of exhaust gas from the mixing ball 36 enters the duct portion 37 through the vent 47 and passes from the exhaust port 49 to the exhaust unit 26 through the exhaust passage 50 meandered by a plurality of meandering action portions 39 protruding into the duct portion 37. Inhaled. Even if the beverage ingredients soared in the mixing ball 36 are mixed with the exhaust gas, it reduces the amount of adhering to the inner surface of the meandering action part 39 and the duct part 37 during the meandering exhaust passage 50 and reaching the exhaust unit 26. it can. Therefore, the filter 138 of the exhaust unit 26 is less likely to be clogged with beverage ingredients, and the frequency of cleaning the filter 138 can be reduced.

  Next, removal of each component for maintenance such as cleaning of the tea machine 11 will be described.

  By removing the chute body 25, each mixing unit 22 and each beverage ingredient supply unit 24 can be removed.

  To remove the mixing unit 22, hold the handle portion 82 of the funnel body 34 and pull it out, so that the locking projections 81 on both sides of the funnel body 34 are disengaged from the locking portions 94 of the mounting members 91 on both sides. The unit 22 can be removed from the mounting portion 23.

  When the mixing unit 22 is removed from the mounting portion 23, the drive side connecting portion 103 of the drive side connecting body 101 of each drive unit 97 is at an arbitrary stop position and is connected to the gear mechanism 98 and the like. Movement is restricted by position. Even if the stirring blade body side connecting portion 70 comes into contact with the stopped driving side connecting portion 103, the stirring blade body side connecting portion 70 escapes while turning, so there is no hindrance to removal. In particular, the driving side connecting portion 103 is provided in a cylindrical shape whose axial direction is the vertical direction, and the stirring blade body side connecting portion 70 is provided in a plate shape along the radial direction from the center of rotation. Even if the stirring blade body side connecting portion 70 comes into contact with 103, the stirring blade body side connecting portion 70 can escape smoothly while rotating.

  Further, the removed mixing unit 22 can be cleaned in a disassembled state by removing the lid 32 to which the plurality of stirring blade pairs 33 are attached from the mixing ball body 31 and separating the mixing ball body 31 and the funnel body 34 from each other.

  Therefore, according to the tea dispenser 11, the stirring blade body 33 formed larger in diameter than the outlet 42 of the mixing ball 36 is formed on the bottom surface portion 41 of the mixing ball 36 with the outlet 42 as the center. Since it is arranged in the rotating space 43, the stirring blade body 33 can be made larger in diameter than in the past, and the rotation of this large diameter stirring blade body 33 can reliably stir and mix the beverage without flowing out from the outlet 42, Further, if the peripheral speed on the outer diameter side of the stirring blade body 33 is set to the same level as the conventional one, the rotational speed of the stirring blade body 33 can be lowered, and the durability of the bearing structure of the stirring blade body 33 can be improved.

  Since notches 68 facing the outflow port 42 are formed in the plurality of blade portions of the stirring blade body 33 facing the bottom surface portion 41 of the mixing ball 36, the foaming of the beverage can be reduced and the foaming can be improved.

  Since the plurality of lower blade portions 66 and the plurality of upper blade portions 67 project from the lower surface and the upper surface of the rotating portion 65 protruding around the rotation shaft 61 of the stirring blade body 33, a plurality of lower blade portions 66 are provided. Thus, the beverage is agitated without flowing out from the outlet 42, the beverage is agitated by the plurality of upper blade portions 67, and the agitation effect of the beverage can be improved.

  The diameter of the stirring blade body 33 is formed to be 80% or more of the width dimension in the direction in which the distance between the inner surfaces of the mixing balls 36 facing each other with the stirring blade body 33 as the center is short. Since hot water and cold water supplied to the ball 36 are diffused and poured out on the stirring blade body 33 in the radial direction of the stirring blade body 33, hot water and cold water are easily scattered over a wide area inside the mixing ball 36, and the beverage It is possible to reduce raw materials and bubbles remaining on the inner surface of the mixing ball 36.

  In addition, as a drink provision apparatus, it can apply not only to the tea dispenser 11 but a cup-type drink vending machine, and the same effect is obtained.
