[

Reference numeral 90 in the reference numerals denotes a cup ascending / descending tool stopper which is taken out of the cup 32 which has been cleaned in the cleaning apparatus section 40 and discharged to the discharge cup disinfection unit 100. "100" The discharge cup disinfection unit disinfects the cup supplied from the ascending / descending tool holding portion (90). The outer end of the discharge cup disinfection unit 100 is installed so as to be exposed to the cup discharge unit 3 so that the user can drink water by taking out the cup located at the distal end of the discharge cup disinfection unit 100, Is a water purifier.

The operation of the present invention will be described with reference to FIGS. 1 to 8. FIG.

In the case of using the cup automatic cleaning apparatus 1 in which the cup cleaning unit 50 according to the present invention is installed, as shown in FIG. 1, the cup discharge guide 101 installed inside the discharge cup disinfection unit 100 The cup 6 placed on the distal end is taken out from the cup discharging portion 3 and is received by the water purifier 110 provided on the cup discharging portion 3 side to drink water.

1 and 3, the cup is fed through the cup feeder unit 10 to the outside of the chain 32 included in the feed screw unit 30, The cup 6 is seated and held on the cup holder 9 provided on the cup holder.

A magnetic body 7 is provided on the bottom surface of the cup 6 and a magnet 8 is provided on the bottom surface of the cup holder 9 so that the cup 6 is held by the magnetic force of the magnet 8, 9).

At this time, the inlet of the cup is in the upward direction. When the inlet is directed downward while descending to the lower side of the upper cup while rotating the chain 32 by the rotation of the sprocket 31, And the cleaning device 40 installed on the lower side of the chain 32 is raised.

As shown in FIGS. 5 and 6, the lifting operation of the cleaning device unit 40 is performed by driving the motor 43 for moving the cleaning device subframe 42 included in the cleaning device unit 40 up and down, The screw 44 is screwed into the screw 44. The screw 44 is screwed into the vertical frame 46 of the cleaning device subframe 42 so that the motor 43 is rotated, The cleaning device frame 42 is lifted and lowered in accordance with the rotation direction of the cleaning device frame 42.

When the cleaning device frame 42 is lifted by this action, the cup 6 mounted upside down on the cup holder 9 provided on the chain 32 as shown in Fig. 4, that is, the cup 6 with the inlet facing downward The cup rinsing unit 70 and the cup drying unit 80 are provided on the upper portions of the casings 63, 77 and 87 respectively provided on the upper side of the cup rinsing unit 50, the cup rinsing unit 70, 86).

When the cups 6, which are inserted upside down into the respective cup-lowering holes 62, 76 and 86, enter the cups, the cups are rinsed, rinsed and dried. Hereinafter, The operation of the cleaning unit 50 will be described.

That is, the operation of the cup washing unit 50 as a main part of the present invention is such that the cup 6 attached upside down to the cup holder 9 through the cup-lowering hole 62 as shown in Figs. 5, 7, 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 cleaning motor 65 installed on the lower side of the cup cleaning unit 50 is driven, the driving force causes the gear 64 engaged with the driving gear 66 of the cleaning motor 65 to rotate. 64 are installed on the inner brush shaft 54 whose lower portion is exposed to the lower side of the housing 51 so that the inner brush shaft 54 is rotated.

A rotating body 59 is fixedly coupled to the upper side outer peripheral edge of the inner brush shaft 54 to rotate together with the inner brush shaft 54 and the rotating body 59. The inner brush shaft 54, The inner brush 53 provided on the upper side of the inner brush shaft 54 rotates inside the cup and cleans the inner surface of the cup.

At this time, a nozzle 56 for spraying the detergent mixture liquid to the side of the inner brush 53 and an outer brush 57 for contacting the outer circumferential surface of the cup are provided outside the central part of the rotating body 59. In the nozzle 56, 53, the outer brush 57 cleans the outer surface of the cup.

The outer brush shaft 58 under the outer brush 57 is provided with an inner gear 61 through an outer brush shaft 58 penetrating through the rotating body 59 downwardly, When the rotary body 59 including the inner brush shaft 54 rotates by engaging with the ring gear 60 provided on the inner surface of the upper side of the housing 51, So that the inside of the cup is cleaned by the inner brush 53 and the outer periphery of the cup is cleaned by the outer brush 57.

The detergent mixture liquid is supplied from the detergent liquid container 69 through the hose 67 to the first flow path 52 formed inside the inner brush shaft 54. The first flow path 52 is connected to the nozzle 56, The detergent mixture supplied to the first flow path 52 is sprayed toward the inner brush 53 through the nozzle 56. [

Since the detergent mixture is a mixture of detergent and washing water, the detergent foam is applied to the outer brush 57 due to the bubbling during the rubbing process due to the injection of the refining liquid into the rotating inner brush 53, It is washed simultaneously.

The cleaning time is determined by washing the inner and outer surfaces of the cup with a friction contact for a few seconds according to the input value inputted by the controller. When the cleaning is performed for a predetermined time (several seconds), the rotating body 59 including the gear 64, The cleaning motor 65 for driving the shaft 58 is stopped,

After the supply of the detergent mixture liquid is stopped, the motor 43 for moving the cleaning device 40 up and down is operated as shown in FIGS. 5 and 6, and the cleaning device subframe 42 provided with the cup cleaning unit 50 is operated Descend.

When the inside and outside surfaces of the cup are cleaned with the detergent mixture liquid by the cup cleaning unit 50 and the cleaning device subframe 42 is lowered, the chain 32 rotates again by one pitch and stops according to the signal of the inputted control unit, The cleaning device subframe 42 provided with the cup cleaning unit 50 rises again to perform the cleaning operation repeatedly.

When the cup cleaning operation is performed in the cup cleaning unit 50 as described above, the detergent mixture liquid is sprayed toward the inner brush 53. The retainer seal 59a is provided on the outer periphery of the rotating body 59, The cleaning agent liquid does not leak into the gap formed between the outer circumferential surface and the inner circumferential surface of the cleaning section casing (63).

An overflow hole 63a is formed in the upper portion of the washing section casing 63 to allow the detergent mixture liquid to fill the outside of the washing section casing 63 when the washing liquid reaches the set water level. A proper amount of detergent mixture is always kept inside.

When the detergent mixture liquid reaches the set level, the overflow hole 63a is filled with the detergent mixture liquid and bubbles, which are buried in the inside of the detergent casing 63, So that the detergent mixture can be relatively cleanly maintained.
