The left and right side plates 27B of the cover 27 are formed with a bent portion 43 bent inward as shown in FIG. 5 in the region from the rear side of the bottom edge to the entire height of the rear edge. Inside the curved portion 43, the above-mentioned heat dissipation plate 26
An insertion groove 44 into which a rear edge can be inserted from a bottom edge of the left and right side plates 26B is formed. Further, from the front edge of the top plate 27A of the cover 27, a mounting plate 46 that overlaps with the rear surface side of the mounting plate 30 of the bracket 29 is formed so as to stand up.
Two through holes 47 are formed corresponding to the through holes 33 of the mounting plate 30 of the bracket 29.

A mounting position of the moisture-proof member 24 is set on the back side of the door 3 described above. As shown in FIG. 1, this mounting position is at a height position corresponding to the discharge port 8 of the canister 7, and at this mounting position, a pair of left and right boss portions 49 are arranged at predetermined intervals as shown in FIG. Formed by each boss 4
A screw hole 50 into which the screw 32 used for attaching the above-mentioned moisture-proof member 24 is screwed is formed in 9.

This embodiment has the above-mentioned structure,
Next, the operation will be described. First, the moisture-proof member 24 is assembled in the following procedure. A bracket 29 is fixed to the heat dissipation plate 26 in advance, and the heater 25 is adhered to the upper surface plate 26A of the heat dissipation plate 26. Next, the cover 27 is inserted into the outside of the heat dissipation plate 26 from the rear. The heat radiating plate 26 is accommodated while the bottom edge and the rear edge of the left and right side plates 26B are inserted into the insertion grooves 44 provided in the both side plates 27B of the cover 27, and the rear edge of the heat radiating plate 26 is located behind the cover 27. When it hits the groove bottom of the insertion groove 44 on the edge side, the coupling plate 35 of the heat dissipation plate 26 overlaps with the lower surface of the coupling plate 40 of the cover 27 so as to overlap, and the projection 41 fits into the corresponding fitting hole 36. . As a result, the heat radiation plate 26 is housed in the cover 27 and assembled integrally. At this time, the two mounting plates 30 and 46 are overlapped with each other so that the respective insertion holes 3
3,47 match each other. The lead wire 25A of the heater 25 is drawn out from a notch hole (not shown) formed in the side plate 27B of the cover 27.

When the moisture-proof member 24 is assembled in this manner, both mounting plates 30 and 46 are brought into contact with the boss portion 49 on the back surface of the door 3, and the screw 32 is inserted through the insertion holes 47 and 33 and screwed into the screw hole 50 of the boss portion 49. As a result, the moisture-proof member 24 is attached to the door 3
It is attached to the mounting position on the back side of. Also, the heater 25
The lead wire 25A is connected to a control unit (not shown) provided on the door 3.

During operation of the tea dispenser, the door 3 is closed as shown by the chain line in FIGS. 1 and 2, and accordingly, the moisture-proof member 24 provided on the back surface of the door 3 causes the upper ends of both shooters 12 to move. Move to the cover position to cover the part. In this cover position, as shown in FIG. 1, the moisture-proof member 24 covers the front surface, the upper surface, and the left and right side surfaces from a position slightly before the upper end portions of the shooters 12 to a position of the root portion of the discharge port 8. In addition, the rear edge side of the upper surface of the moisture-proof member 24 is an inclined surface 52 which is formed by the connecting plates 35 and 40, and is inclined downward.
The upper surface side of the root portion of the discharge port 8 is completely covered while avoiding the interference with the front surface.

When the heater 25 is energized, the heat radiation plate 26 is heated and heat rays are radiated. Since the heat dissipation plate 26 is formed in a shape covering the front surface, the upper surface, and the left and right side surfaces of the upper end portion of the shooter 12, the inside of the upper end portion of the shooter 12 including the discharge opening 8 is efficiently heated, and the upper surface of the discharge opening 8 is also formed. Since the openings are opened, the inside of the discharge port 8 is also well heated and becomes a dry atmosphere. This prevents the moisture rising from the mixing container 14 from entering the canister 7 through the discharge port 8.

On the other hand, when the door 3 is opened as shown by the solid line in FIG. 2, the moisture-proof member 24 moves to the open position where the upper part of the shooter 12 is opened. Therefore, the shooter 12 and the discharge port 8 can be easily removed by removing them as needed. When cleaning is completed and the door 3 is closed, the moisture-proof member 24 is automatically brought back to the cover position.

As described above, according to this embodiment,
When the door 3 is opened, the moisture-proof member 24 moves to a position separated from the position where the upper end portion of the shooter 12 is covered and is stopped, so that the moisture-proof member 24 does not interfere with the shooter 1.
2 and the discharge port 8 can be cleaned. When the door 3 is closed after cleaning, the moisture-proof member 24 comes to the position of covering the upper end portion of the shooter 12 again, so that the user cannot forget to set the moisture-proof member 24. In addition, since the inclined surface 52 is formed by bending at the rear edge of the upper surface of the moisture-proof member 24, the upper surface of the root portion of the discharge port 8 can be completely covered without interfering with the front surface of the canister 7, and moisture can be prevented. Intrusion can be prevented more reliably.

Since the heat radiating plate 26 is formed in a box shape capable of covering the front surface, the upper surface and the left and right side surfaces at the upper end portions of both shooters 12, a large heat radiating area is provided and the upper end portions of the shooter 12 are effectively heated. The moisture-proof effect can be enhanced. The heat sink 26 and the cover 27 are assembled by the heat sink 2
This is done by inserting the end edge of the side plate 26B of No. 6 into the insertion groove 44 formed in the end edge of the side plate 27B of the cover 27, and the heat dissipation plate 26 and the cover 27 can be easily and firmly assembled.
