[0012]
An inlet / outlet port 50 through which the impeller 31 can be taken in and out is formed at the lower end of the front surface of the mixing container 15. Specifically, the entrance / exit 50 is formed in a cylindrical shape that is slightly larger than a semicircle constituting the bottom wall 15A. In the portion where the insertion groove 28 is formed, an arc-shaped portion extending to the back side of the peripheral wall of the entrance 50 forms the bottom wall 15A.
A cap 60 is detachably attached to the entrance 50.
[0013]
As shown in FIGS. 5 and 6, the cap 60 has a sealing plate 62 stretched on the inner end face of the cylindrical portion 61 that fits almost tightly inside the entrance / exit 50, and a flange 63 on the outer periphery. It is formed in a shape provided over the entire circumference. On the outer peripheral surface of the cylindrical portion 61 of the cap 60, a mounting groove 64 into which the seal ring 65 can be fitted is formed over the entire circumference. As shown in detail in FIG. 7, a notch groove 66 is formed in a region of a certain length on the side wall on the inner side (right side in FIG. 5) of the mounting groove 64. The side wall of the mounting groove 64 and the corner portion of the notch groove 66 are rounded so as not to damage the seal ring 65.
[0014]
A plate-like knob 67 facing in the radial direction protrudes from the outer surface of the cap 60 and holds the impeller 31 concentrically with the support shaft 30 at the center of the sealing plate 62. A holding shaft 69 is projected.
Further, as shown in FIG. 6, a pair of locking claws 70 are further provided on the outer peripheral edge of the flange 63 at positions corresponding to both ends of the knob 67. The front end surface of each locking claw 70 in the clockwise direction is an inclined surface 71 that is first lowered.
[0015]
On the other hand, as shown in FIG. 7, the aforementioned entrance / exit 50 is formed such that the width of the protruding end face 51 is wide in the upper half circumference. On both the left and right sides of the center of the entrance / exit 50, a pair of locking portions 52 are formed so as to project further toward the front side and the outside. An arc-shaped locking groove 53 that continues from the protruding end surface 51 is formed on the inner surface of each locking portion 52. Each locking groove 53 is open at the rear end side in the clockwise direction when viewed from the front to form an introduction port 54, and forms a stopper wall 55 at the front end side in the clockwise direction as a dead end. The ceiling surface of the introduction port 54 is an inclined surface 54A that is widened toward the opening end side for guide.
Further, a protruding wall 57 protruding further toward the front is formed on the outer peripheral side in the upper half region of the protruding end face 51 of the doorway 50. The protruding wall 57 is connected to the locking portion 52 at the left end in FIG. 7, but a predetermined gap 58 is opened between the protruding wall 57 and the locking portion 52 at the right end. Further, a removal guide surface 59 is formed at the right end of the protruding wall 57 and has an upward slope in the counterclockwise direction.
[0016]
This embodiment has the structure as described above, and the operation thereof will be described subsequently.
In the mixing container 15, the filter holder 42 on which the filter 45 is laid is inserted into the insertion groove 28. At the same time, the impeller 31 is inserted through the entrance 50 and inserted into the support shaft 30. Subsequently, the cap 60 is attached to the entrance 50. In that case, after first fitting the seal ring 65 into the mounting groove 64, the knob 67 is picked, and the gap between the one locking claw 70 and the locking portion 52 adjacent to the guide surface 59 of the protruding wall 57. The cap 60 is fitted toward the entrance / exit 50 so as to be positioned at 58.
The cylindrical portion 61 of the cap 60 is pushed in until the flange 63 abuts against the protruding end surface 51 of the entrance / exit 50 while elastically compressing the seal ring 65, and one locking claw 70 is locked with the guide surface 59 of the protruding wall 57. The other locking claw 70 is in a state of protruding outward from the protruding end surface 51 on the front side in the clockwise direction of the other locking portion 52 between the portion 52 and the wide end portion of the protruding end surface 51. .
[0017]
Subsequently, when the cap 60 is rotated in the clockwise direction as viewed from the front, the locking claw 70 turns from the introduction port 54 into the locking groove 53 of the locking portion 52. At this time, since the inclined surface 71 is formed at the tip of the locking claw 70 in the rotation direction, and the opening 54 is also widened on the opening end side, the locking claw 70 is introduced into the locking groove 53. Is done smoothly. When the tip of the locking claw 70 hits the stopper wall 55 at the back of the locking groove 53, the rotation operation is stopped, and the cap 60 is attached to the doorway 50 in a state of being prevented from coming off. At this time, the seal ring 65 fitted to the outer periphery of the cylindrical portion 61 of the cap 60 is elastically sealed over the entire circumference of the inner peripheral surface of the doorway 50, so that it is sealed in a watertight manner. Further, a pressing shaft 69 protruding from the inner surface of the cap 60 presses the center of the front surface of the impeller 31 and supports the impeller 31 together with the support shaft 30 from the front and rear.
[0018]
When the dispensing switch is turned on in this state, the screw device 18 provided in the canister 14 is driven for a predetermined time, and a predetermined amount of powdered tea T is discharged from the discharge port 16 and falls through the shooter 19. And supplied to the mixing container 15. At the same time, the valve 22 is opened for a predetermined time, and a predetermined amount of hot water (or cold water) is supplied from the liquid supply pipe 21. Moreover, the impeller 31 is rotationally driven by starting the motor 36, the hot water supplied into the mixing container 15 and the powdered tea T are stirred and mixed, and the powdered tea T is dissolved in the hot water to produce tea. . The produced tea is poured from the spout 39 through the circular hole 44 in a state in which the powder tea T or the foreign matter that does not completely melt is crushed and removed by the filter 45, and passes through the spout hose 40. It is poured into the cup A placed on the placing portion 13.
[0019]
When the above-described pouring operation is repeated, the inner surface of the mixing container 15 is gradually soiled by the undissolved powdered tea T, tea astringent, water stains, etc., especially the impeller 31 is easily soiled, and the undissolved powdered tea T and the water stains. As a result, the filter 45 gradually becomes clogged. Therefore, the inside of the mixing container 15 is cleaned. In that case, the door 12 is opened and the shooter 19 is first removed. Next, as shown in FIG. 6, the lid 24 is removed while being inclined, and the dispensing hose 40 is also removed.
[0020]
Subsequently, when the knob 67 is picked and the cap 60 is rotated counterclockwise as viewed from the front, the locking claw 70 comes out of the locking groove 53. When further rotating in the same direction, one locking claw 70 rides on the projecting end of the projecting wall 57 while being guided by the guide surface 59 of the projecting wall 57, and accordingly, the cylindrical portion 61 of the cap 60 moves forward from the doorway 50. It is automatically pulled out. Accordingly, the cap 60 is smoothly removed from the doorway 50. If it does so, a hand may be put in from the entrance / exit 50, the impeller 31 may be extracted from the support shaft 30, and the impeller 31 should just be washed with water etc. outside.
Moreover, since the filter holder 42 can also be taken out along the insertion groove 28, the filter 45 is removed from the filter holder 42 and the filter 45 is cleaned or replaced. Since the spout 39 is also exposed by removing the filter holder 42, the spout 39 can be thoroughly cleaned using the entrance 50.
[0021]
In addition, when exchanging the seal ring 65, a finger can be inserted from the notch groove 66 of the mounting groove 64, and the seal ring 65 can be easily removed while being spread. When the cleaning is completed, the filter 45, the filter holder 42, and the impeller 31 may be attached, and the cap 60 and the like may be attached according to the reverse procedure of the above removal.
[0022]
As described above, according to the present embodiment, since the relatively small entrance / exit 50 dedicated to the insertion / extraction of the impeller 31 is formed on the front surface of the mixing container 15 and the cap 60 is attached / detached thereto, the impeller 31 is mounted on the front surface. It can be easily inserted and removed from the side, and the cap 60 itself can be easily attached and detached. Further, since the seal ring 65 fitted to the cylindrical portion 61 of the cap 60 is brought into close contact with the inner peripheral surface of the entrance / exit 50, high sealing performance can be obtained. Since the seal ring 65 is fitted and supported in the mounting groove 64 of the cap 60, the seal ring 65 is not accidentally detached and lost when the cap 60 is removed. On the other hand, since the notch groove 66 is cut in the mounting groove 64, the seal ring 65 can be easily replaced by inserting a finger or the like.
[0023]
Since the so-called bayonet method using the locking claw 70 is adopted as the mounting structure of the cap 60, the complicated structure can be reduced compared with the screw-in type, and the teacups and the like are less likely to collect and are hygienic. Since two locking portions 52 for locking the locking claws 70 are provided at intervals of 180 degrees, a strong locking force can be obtained with a simple structure.
In addition, since the guide inclined surfaces 71 and 54A are provided at the tip of the locking claw 70 and the introduction port 54 of the locking groove 53, the locking claw 70 is smoothly guided into the locking groove 53. On the other hand, when the cap 60 is rotated by a predetermined angle in the removal direction, the locking claw 70 rides on the protruding wall 57 and the cylindrical portion 61 of the cap 60 automatically comes out of the entrance / exit 50, so that the removal operation is performed smoothly. be able to.
