DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup type vending machine which puts a beverage in a cup and dispenses the beverage.

[0002]

2. Description of the Related Art A cup type vending machine of this type is constructed as shown in FIG. A hot water tank 1 for producing hot water B used for cooking, a water bath 2 for producing cold water C for cooking, and the like are stored in a compartment A of the vending machine main body. Cold water C is produced by pumping tap water from a reservoir tank 4 into a cooling coil 3 immersed in cold water D of a water bath 2.

The pump 5 is also used to supply water to the hot water tank 1 and to a carbonator tank 6 for producing carbonated water E used for cooking. In the carbonator tank 6,
Carbon dioxide gas F is blown into the cold water C sent through the cooling coil 3 to produce carbonated water E.

[0004] The selling operation is performed as follows. Raw material G corresponding to the selected flavor is dispensed to ball 7, and hot water B is dispensed from hot water tank 1 to ball 7. In the ball 7, the raw material G is dissolved in the hot water B and poured into the cup 9 which is paid out to the cup station 8 facing the product outlet.

[0005] In the above example, a hot beverage is sold. In the case of a carbonated beverage as a cold beverage, cold water C is poured into the cup 9 from the cooling coil 3, and the carbonated water is further poured into the cup 9 from the carbonator tank 6. Water E is poured. When the syrup raw material H is necessary, the syrup raw material H in the syrup tank 11 which is cooled by being immersed in the cold water D in the water bath 2 is injected into the cup 9.

Wastewater J generated at the cup station 8
Are collected in a drain bucket 12 installed in the vending machine. Note that the drainage water J when the balls 7 and other parts are washed is also collected in the drainage bucket 12.

The drain bucket 12 is provided with a drain bucket level switch SW1 for detecting a state in which the water level reaches the reference level K1. Based on the hot water dispensing instruction M, the cold water dispensing instruction N, and the syrup dispensing instruction P, which are generated according to the user's selection of the product, the war pump 5, the syrup pump 10, the first and second valves 13 and 14, the hot water valve. The sales control unit 16 that controls the operation of the hot water tank 15 includes a hot water tank level switch 17 that detects a decrease in the water level of the hot water tank 1.
A water supply instruction Q from the reservoir tank 4 and a water supply instruction R from the reservoir tank level switch 18 for detecting a decrease in the water level of the reservoir tank 4 are also supplied, and the war pump 5 is supplied as necessary.
And the operation of the first and second valves 13 and 14 is controlled.

The sales control section 16 is constructed so as to perform a sold-out transmission S by operating as shown in FIG. 5 in accordance with the detection output of the drain bucket level switch SW1. When it is confirmed that the water level of the drainage bucket 12 has reached the reference level K1 from the drainage bucket level switch SW1 in # 1, #
In # 2 and # 4, it is determined whether the water supply instruction R from the reservoir tank level switch 18 or the water supply instruction Q from the hot water tank level switch 17 has occurred, and the water level of the drainage bucket 12 has reached the reference level K1. However, the normal selling operation is continued until the water supply instruction Q or the water supply instruction R is generated, and the water supply instruction Q or the water supply instruction R is given in # 2 or # 4.
When it detects "," the water supply operation is not executed, and the sold out message S is sent in # 3 to prohibit the sale.

[0009]

As described above, when the water supply instruction Q or the water supply instruction R is detected from the drain bucket level switch SW1 while the water level of the drain bucket 12 has reached the reference level K1, the sold out signal S is sent and the drain is sent. Although the rise of the water level of the bucket 12 is suppressed, if an abnormality occurs and the syrup pump 10 falls into a continuous operation state, the water supply operation is not executed even if the water supply instruction Q or the water supply instruction R is detected. In this way, even if you execute the sold-out call S, the drain bucket
No. 12 overflows due to the flow of the syrup raw material H, and there is a problem that the inside A of the vending machine is contaminated.

An object of the present invention is to provide a cup-type vending machine which can surely prevent a drain bucket from overflowing.

[0011]
