Side at first housing 21 has a slit 25, so that with lead formula well heater 26 fixing insertions wherein.

In addition, when freezing to cover 80 when being meshed with waterproof, rib 23 should freeze to cover 80 lower surface with waterproof and closely contact and protrude upward with predetermined altitude, and the upper surface of first housing 21 should favour its corner part so that guide the water of institute's seepage downwards.

Fig. 5 A is the water dispenser used water guide cover vertical view of explanation for automatic vending machine of the present invention, and Fig. 5 B is along the sectional view of Fig. 5 A center line V-V ' according to the present invention.

This water guide cover 60 comprises rectangle second housing 61 that matches with motor casing 20 upper surfaces, and at the formed conjugate foramen 62 of second housing, 61 each corner, be used for be formed on motor casing 20 on first conjugate foramen 24 match.

Side at second housing 61 is formed with a water inlet 63, water is imported by this water inlet so that match with the rotation of impeller 40, and a wheel rotation groove 64 that communicates with water inlet 63, be formed at the lower surface of second housing 61, so that impeller 40 rotates therein.

One circular engaging groove 65, shown in Fig. 5 A, be formed on the lower surface of second housing 61, be used for forming a plurality of steps along wheel rotation groove 64 directions, one ajutage 66 is formed on second housing, 61 upper surfaces and communicates with wheel rotation groove 64, discharges so that will be introduced into the water of water inlet pipe 63 by the rotation of impeller 40.

The horizontal slice view that Fig. 6 A freezes to cover for the used waterproof of water dispenser of automatic vending machine of the present invention for explanation, Fig. 6 B shows the face view for cuing open along Fig. 6 A center line VI-VI '.

This waterproof freeze to cover 80 comprise one in order to first and

second housings

21 and 61 rectangles that match the 3rd housing 81, and the 3rd conjugate foramen 82 that is formed on the 3rd housing 81 each corner is in order to match with first and

second conjugate foramens

24 and 62.

Be formed with a through hole 83 at the 3rd housing 81 cores, be used to guide the lead formula well heater guide channel 84 of lead formula well heater 26 in the 3rd housing 81 1 sides formation one.

One lead formula well heater curved slot 85 be formed at the lower surface of the 3rd housing 81 with spiral fashion and from the core of through hole 83 with spiral extension, in order to hold lead formula well heater 26, and be formed with mate 86 at the upper surface of the 3rd housing 81, so that the engaging groove of water guide cover and its engagement.

In addition, annular first O-ring seal 87 as shown in Figure 3, is set on the outside surface of mate 86, so that prevent the seepage of water between mate 86 and the water guide cover 60.This lead formula well heater curved slot 85, shown in Fig. 6 A and 6B, from lead formula guide channel 84 formed positions, constitute with spiral, concentric shape along clockwise direction with 270 °, this lead formula guide channel 84 curl and be oval in 270 °-360 ° angular range therefrom breaks away from so that prevent the lead formula well heaters 26 that are inserted in the lead formula guide channel 84.

Explanation shown in Figure 7 is the cross-sectional view strength of the amplification of second seal among Fig. 3 according to the present invention.

As shown in the figure, second seal 90 is set in the through hole 83 that waterproof freezes to cover so that the seepage of anti-sealing.This second seal 90 comprises one the 4th housing 91, and a jack 92 that is formed at the 4th housing 91 cores, so that turning axle inserts among this jack 92.

First hermetic unit 93 is formed on the periphery of the 4th housing 91 with spiral fashion, be used for sealing along the inside periphery of through hole 83, when on the periphery of the inside of jack 92, being provided with second hermetic unit 94 and inserting jacks 92, the periphery of turning axle 22 is sealed with convenient turning axle 22.

Below, will the operation and the effect of the water dispenser of automatic vending machine of the present invention be illustrated.

When this device was switched on, driving motor (not drawing) just was driven, and rotated thereby make in the impeller swivelling chute 64 of impeller 40 on water guide cover 60 that is arranged on the driving motor.

When impeller 40 rotated, the water that is contained in the water storage container 7 was introduced in the water inlet 63 of water guide cover 60 by penstock 9, and the water that so is imported into is discharged from by drainpipe 66 and is fed in the mixing of materials device 5 by water supply hose 8.

By the pressure that is introduced into water in the water supply hose 8 a small amount of gas in the feed pipe 8 is entered rapidly in the mixing of materials device 5.

In addition, during lead formula well heater 26 in electric current is applied to lead formula well heater curved slot 85, lead formula well heater 26 just can discharge heat.

Therefore the heat that sends is transferred into waterproof by mate 86 and freezes to cover on 80 and the water that the water inlet 63 by water guide cover 60 is imported is heated to a predetermined temperature.

A spot of water owing to its current are hindered by the upper surface of wheel rotation groove 64 and mate 86, thereby may produce seepage near rotation axis 22 when rotation axis 22 rotates.Water along turning axle 22 periphery seepages can flow along second hermetic unit 94 of second seal 90, and can flow along first hermetic unit 93 of second seal 90 along the water of second seal, 90 periphery seepages.

Thereafter, the water that reaches motor casing 20 by first and second hermetic units 93 and 94 can flow to each corner of motor casing 20 under the effect of the inclined upper surface of motor casing 20.

As mentioned above, according to the present invention, the water dispenser that is used for automatic vending machine can constitute the more compact automatic vending machine of structure, thereby has reduced manufacturing cost.

In addition, because the present invention supplies the used water dispenser of automatic vending machine to be set under the water level of water storage container, thereby can more promptly supply water, thereby strengthened reliability of products.

In addition, when ambient temperature was very low, the present invention can also prevent freezing of sealing, thereby had strengthened reliability of products.

Though, for purpose of the present invention is described most preferred embodiment of the present invention is disclosed, but do not require under the condition of the scope of the invention narrated and spirit breaking away from respective right, those skilled in the art can understand its difference of carrying out is improved, replenished and conversion.
