Is inserted, and the wire heater winding groove 85 is formed concentrically with respect to the wire heater guide groove 84 up to 270 ° in the clockwise direction, and is formed in an elliptical shape between 270 ° and 360 °. The wire heater 26 inserted in the wire heater guide groove 84 is prevented from coming off.

In the second packing 90, as shown in FIG. 6, the second packing 90 is inserted into the through hole 83 of the above-mentioned antifreeze cap 80 so as to prevent the leakage of drinking water. A fourth main body 91 is formed in a shape, and an insertion hole 92 is formed in the center of the fourth main body 91 so as to insert the rotation shaft 22 of the drive motor (not shown).

The outer peripheral edge of the fourth main body 91 is packed along the inner peripheral edge of the antifreeze cap 80,
The first packing portion 93 is formed to project in a spiral shape, and the second packing portion is formed so as to be packed along the outer peripheral edge of the rotary shaft 22 when the rotary shaft 22 is inserted into the outer peripheral edge of the insertion hole 92. A protrusion 94 is formed in a spiral shape. The operation process of the drinking water supply device of the vending machine according to the present invention configured as described above is as follows.

When a current is applied, a drive motor (not shown) rotates, and the impeller 40 into which the rotation shaft of the drive motor is inserted is positioned inside an impeller rotation groove 64 formed in the drinking water guide cap 60. Rotate. When the impeller 40 rotates in this manner, the drinking water in the drinking water tank 7 flows into the inflow pipe 63 of the drinking water guide cap 60 through the drinking water inflow hose 9, and the inflowing drinking water flows through the outflow pipe 66. It flows out and is supplied to the material supply tank 5 through the drinking water supply hose 8.

At this time, a predetermined amount of air remaining in the drinking water supply hose 8 is quickly discharged to the material mixing tank 5 by the pressure of the drinking water flowing into the drinking water supply hose 8. When an electric current is applied to the wire heater 26 inserted in the wire heater winding groove 85, heat is generated from the wire heater 26, and the heat is transmitted through the coupling plate 86 of the anti-freezing cap 80 to guide the drinking water. The drinking water flowing into the inflow pipe 63 of the cap 60 is heated and maintained at a predetermined temperature.

On the other hand, the drinking water limited by the upper surfaces of the impeller rotating groove 64 and the coupling plate 86 may leak a small amount of water around the rotating shaft 22 due to the rotation of the rotating shaft 22. At this time, the drinking water that has leaked flows along the first packing portion 93 and the second packing portion 94 of the second packing 90, and the drinking water that has reached the upper surface of the motor housing 20 is
Due to the slight angle of inclination of the upper surface, it flows to each corner side of the motor housing 20.
