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 used for cooking, and the like are housed in an inside A of the vending machine body. The cold water C is made by sending tap water from the reservoir tank 4 to the cooling coil 3 immersed in the cold water D of the water bath 2 by the pump 5.

The pump 5 is also used for supplying water to the warm water tank 1 and supplying water to the 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.

The selling operation is carried out as follows. The raw material G corresponding to the selected flavor is dispensed to the balls 7, and the hot water B is dispensed from the hot water tank 1 to the balls 7. In the ball 7, the raw material G is melted by the hot water B and poured into the cup 9 dispensed to the cup station 8 facing the product outlet.

The above example is the operation of selling hot beverages. In the case of a cold beverage and a carbonated beverage, cold water C is poured from the cooling coil 3 into the cup 9, and the carbonator tank 6 is carbonated into the cup 9. 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 judged 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 is generated, 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 reaches the reference level K1, the sold out signal S is sent and the drainage is performed. 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 sales control device which can surely prevent the drain bucket 12 from overflowing.

[0011]

The sales control device of the present invention detects the water level of a drainage bucket that receives wastewater generated in the vending machine, and when the water level of the drainage bucket reaches a reference level, A cup-type vending machine that switches to a sold-out state when detecting a water supply instruction from the outside of a vending machine to a reservoir tank that stores tap water or a hot water tank that makes hot water used for cooking is switched to a sold-out state A full water detection switch is provided to detect that the water level has reached a specified level higher than the reference level, and at the time of detecting that the full water detection switch has reached the specified level, power is supplied to at least a device that causes drainage. It is characterized by providing a sales control unit for stopping the.
