That is, the operational relationship of the washing device unit 40, which is the main part of the present invention, is the cup 6 attached upside down to the cup holder 9 through the cup elevating hole 62 as in FIGS. 3 and 5 (b). ) is inserted, the inner brush 53 is inserted into the cup, and the outer brush 57 is in contact with the outer surface of the cup.

In this state, when the washing motor 65 installed on the lower side of the cup washing unit 50 is driven, the driving force of the washing motor 65 rotates the inner brush shaft 54 through the gear 64 .

A rotating body 59 is fixedly coupled to the upper outer periphery of the inner brush shaft 54 so that the inner brush shaft 54 and the rotating body 59 become one body and rotate together, and the inner brush shaft 54 is rotated together. As this is rotated, the inner brush 53 installed on the upper side of the inner brush shaft 54 rotates inside the cup to clean the inner surface of the cup.

At this time, on the outside of the center of the rotating body 59, a nozzle 56 for spraying the detergent mixture toward the inner brush 53 and an outer brush 57 contacting the outer peripheral surface of the cup are installed, so that the nozzle 56 has an inner brush ( 53) while spraying the detergent mixture to the side, the outer brush 57 cleans the outer surface of the cup.

The outer brush shaft 58 below the outer brush 57 penetrates the rotating body 59 downward, and an inner gear 61 is installed on the penetrating outer brush shaft 58, the inner gear 61 is meshed with the intermediate gear 61a, and the other side of the intermediate gear 61a is meshed with the ring gear 60 installed on the inner surface of the upper side of the housing 51.

Therefore, when the rotating body 59 including the inner brush shaft 54 rotates in the "a" direction, the shaft of the intermediate gear installed at the eccentric position of the rotating body 59 and the outer brush shaft 58 are also rotating bodies. is rotated along the direction of rotation, the intermediate gear 61a meshes with the ring gear 60 to rotate in the opposite direction to the inner brush shaft 54, and the internal gear 61 meshes with the intermediate gear 61a is "c" ", and rotates in the opposite direction to the intermediate gear 61a.

At this time, the inner brush 53 which rotates in contact with the inner circumferential surface of the cup 6 and the outer brush 57 installed on the outer brush shaft 58 rotate in the same direction, but on the inner and outer surfaces of the cup 6 . The inner and outer brushes 53 and 57 in contact with each other are in frictional contact in opposite directions as in "a" and "c", so that the cup does not rotate along the inner brush 53 or the outer brush 57, so that the inner and outer surfaces of the cup and The frictional resistance with the facing inner and outer brushes 53 and 57 increases, so that the inner and outer surfaces of the cup are thoroughly cleaned.

As above, when the inner and outer brushes 53 and 57 frictionally contact the inner and outer surfaces of the cup, the detergent mixture in which the detergent and washing water are mixed is sprayed toward the inner brush 53 through the nozzle 56, resulting in bubbles in the friction process. As this occurs, detergent foam is also applied to the outer brush 57, thereby simultaneously washing the inner and outer surfaces of the cup.

The above washing is performed by rubbing the inner and outer surfaces of the cup for several seconds according to the input value input by the controller. After stopping, the motor 43 for raising and lowering the washing device 40 is operated to lower the washing device frame 42 .

After that, the chain 32 rotates again by one pitch and stops according to the input signal from the control unit, and the washing device frame 42 rises again, and the cup washing unit 50, the cup rinsing unit 70, and the cup drying A cup at a position corresponding to that of the unit 80 is inserted, and another cup cleaning operation is performed by the cup cleaning unit 50, and as the chain 32 moves by one pitch in this way, the first cup cleaning operation is performed. The cup 6 washed by the unit 50 is inserted into the rinsing unit casing 71 of the cup rinsing unit 70 as shown in FIGS. 3 and 6 to perform rinsing.

At this time, tap water flows into the hot water tank 79 through the hose 78a installed on the lower side of the cup rinsing unit 70, and the tap water is supplied and blocked by a timer included in the control unit. The tap water is supplied for a period of time (minutes) set by the timer at a water pressure as low as that of spring water.

In this state, the tap water flowing into the hot water tank 79 is heated primarily by the heater 79a installed on the outer periphery of the hot water tank 79 to become hot water, and this hot water is directed upward to the upper side of the hot water tank 79. It is supplied to the installed vertical pipe (78).

At this time, the upper end of the vertical pipe 78 is spaced apart from the upper surface of the base cap part 76a located below the high-temperature water discharge member 76, and the water pressure supplied to the vertical pipe 78 is the degree to which the spring water springs out. The hot water is supported in the heater chamber 75 under the base cap part 76a as the low pressure of The hot water contained in the heater chamber 75 is heated secondly to become hot water boiling as hot as 100°C.

In this state, as the water level of the high-temperature water gradually increases, it fills the base cap part 76a and the vertical pipe part 76b on the upper side thereof. Among the through-holes 76c, it leaks from the lower through-hole 76c to the high-temperature water chamber 74 outside the vertical pipe portion 76b through the upper through-hole 76c according to the water level.

As the water level of the high-temperature water gradually increases and exceeds the upper part of the rinsing unit casing 71, the high-temperature water flows over the upper side of the rinsing unit casing 71 and flows down to the horizontal portion 45 of the washing device frame 42, It is drained to the drain port 46 formed at a predetermined position on one side of the horizontal portion 45 without flowing down to the outside by the wall portion 45a installed on the outside of the horizontal portion 45, and a hose ( (not shown) to be installed and drained into the sewer.

As such, when the level of hot water in the rinsing unit casing 71 increases, the cup is not washed and tap water is continuously supplied by the operation of the timer. In this case, automatic cup washing including the present invention When the device 1 is initially operated and when the user stops using it after using it in a row, when the high-temperature water overflows into the upper part of the rinsing unit casing 71, in the previous stage, that is, the cup washing unit 50 Since the high-temperature water mixed with the detergent foam component soaked in the washing process overflows, the inside of the rinsing unit casing 71 and the high-temperature water are kept clean.

When the cup 6 is inserted as shown in FIG. 6 in a state in which the rinsing unit casing 71 is filled with hot water, the hot water contained in the rinsing unit casing 71 as much as the volume of the cup moves to the upper side of the rinsing unit casing 71. It overflows, and as the cup is continuously washed, the level of hot water in the rinsing unit casing 71 is lowered, and as the cup is submerged in hot water boiling at 100°C, the detergent bubbles on the cup are rinsed and sterilized. do.

When the cup is inserted into the rinsing unit casing 71 in a state where the water level of the high temperature water chamber 74 provided inside the rinsing unit casing 71 is lowered in the process of rinsing and sterilizing the cup in this way, it is reversed Air is contained in the inner space of the cup to be inserted, and when the cup starts to be inserted under the water in this state, the air contained in the inside of the cup starts to enter the inside and outside of the vertical pipe portion 76b.

At this time, just before the lower end of the upside-down cup is inserted into the water surface, the air outside the vertical pipe part 76b exits to the high temperature water chamber 74 side, and the air flowing into the vertical pipe part 76b is vertical through the through hole 76c. It exits to the outside of the pipe part 76b and then to the high temperature water chamber 74 side to minimize the buoyancy force, thereby minimizing the overflow of the high temperature water inside the high temperature water chamber 74 to the outside.

As described above, a plurality of through-holes 76c are formed in the vertical pipe portion 76b in which the opened lower part of the cup is to be inserted into the water surface, so that the air in the cup is discharged through the through-holes 76c having the water level close to it.

As in the above description, when the cup washing is continued and the water level for the hot water in the hot water chamber 74 is below the middle of the cup height, the high temperature boiling by the heater 77 is As the water vibrates together with the generation of bubbles, high-temperature steam is generated, so the inside and outside surfaces of the cup are rinsed and sterilized by the high-temperature steam.

After the rinsing operation is performed for a set time, the washing device frame 42 descends again, and when the chain 32 rotates by one pitch and stops again, the washing device frame 42 rises again. As shown in 3, the cup after rinsing is inserted into the drying unit casing (81) formed in the cup drying unit (80).

In this state, the wind generated by the blower 85 of the cup drying unit 80 is blown into the drying unit casing 81 through the blower pipe 84. Inside the drying unit casing 81 above the blower pipe 84. The heater 83 is installed in the heater 83, hot air blows on the cup 6 hung upside down on the upper side of the heater 83 to dry the cup.

At this time, below the heater 83 inside the drying unit casing 81, a blower pipe mounting plate 82 that blocks the heat of the heater 83 from escaping to the lower side of the drying unit casing 81 is installed, so that the hot air is discharged from the drying unit casing. (81) does not escape to the lower side, and only the upper side where the cup is hung, the hot air rises, effectively drying the cup.

And, in the present invention, water (hot water) boiling at 100° C. in the cup rinsing unit 70 and high-temperature steam generated during the boiling process of the hot water come into contact with the metal cup, and the heat is conducted to the cup. Therefore, it is revealed that there is an effect of drying even in the process of moving the cup to the cup drying unit 80 .
