Abstract

PURPOSE:To simultaneously sell a hot drink and a cold drink by simultaneously conducting a heating device for selling the hot drink and a cooling device and an ice-machine for selling the cold drink. CONSTITUTION:The heating device 1 for selling the hot drink, the cooling device 3 and the ice-machine for selling the cold drink and a power detection means 8 detecting that plural power sources are connected are provided. Then, an operation control part 9 controlling the heating device 1, the cooling device 3 and the ice-machine 5 in spite of the priority of the heating device, the cooling device and the ice-machine when the power detection means 8 detects the connection of plural power sources is provided. Thus, the hot drink and the cold drink can simultaneously be sold. Since the power detection means 8 detects the connection of plural power sources, it can be prevented that the heating device 1, the cooling device 3 and the ice-maker 5 are simultaneously conducted owing to erroneous setting.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for a vending machine for dispensing hot and cold beverages.

BACKGROUND OF THE INVENTION In recent years, it has become standard for vending machine control devices to sell hot and cold beverages at the same time (for example, Japanese Patent Laid-Open No. 134788/1983).

An example of a conventional vending machine control device will be described below with reference to the drawings. FIG. 3 shows a schematic configuration of a vending machine that sells hot drinks and cold drinks. 1o is a hot water tank for storing hot water.In order to keep up with the sales of hot beverages, this hot water tank 10 is divided into upper and lower tanks, and a heater 1a is installed in each of the upper and lower tanks. , 1b and temperature sensors 11a and 11b for detecting the hot water temperature.

6 is an ice maker that makes ice for recalled beverages using the power of a compressor 12; 13 is a water amount detection switch installed at the top of the ice maker 6 for detecting the amount of water; When a predetermined amount of ice is produced, the water amount detection switch 13 is turned on and the compressor 12 is stopped. Reference numeral 3 denotes a water tank that stores cold water therein for cooling drinks and dilution water delivered from the water reservoir 3a, and this water tank 3 is provided with a cooling pipe 3b. 14 is a compressor for producing cold water in the water tank 3; 16 is a compressor for producing cold water in the water tank 3;
This is a temperature sensor for detecting the temperature of cold water in the water tank 3.

By providing the above configuration, a hot beverage can be sold by discharging both the raw material from the raw material discharging device (not shown) and hot water from the hot water tank 1° into the cup, while when selling a cold beverage, Drinking water is cooled by passing through the cooling pipe 3b of the water tank 3, and the ice making machine 6
Cold drinks were sold by dispensing them into cups with ice.

Then, at the time of starting, the heating heater 1a.

1b and compressor 12.14 start at the same time,
To avoid the problem of exceeding the contracted current or outlet capacity, each device is controlled in a predetermined order. In addition, since the sales ratio of hot drinks and cold drinks differs depending on the season, in order to sell efficiently, the heaters 1a and 1b for heating or the compressors 12 and 14 for cooling may be changed depending on whether emphasis is placed on hot drinks or cold drinks. A switch is provided to select which one should be operated with priority. As a result, the number of hot beverages sold is greater than the number of cold beverages sold in winter, so the heating heaters 1a, 1
By giving priority to operation b, emphasis is placed on storing a large amount of hot water for ice making, and the heating heaters 1a and 1
(b) is energized, and hot water is stored in the upper and lower tanks of the hot water tank 10. On the other hand, in the summer, priority is given to the operation of the cooling compressors 12 and 14, and once hot water is secured in the upper tank of one of the hot water tanks 10, emphasis is then placed on the operation of the compressors 12 and 14. It looks like this.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, since either cold drinks or hot drinks are given priority during operation, the demand for hot drinks and cold drinks becomes equal at the change of seasons. If one of the drinks is temporarily sold out, or even if cold drinks are prioritized because cold drinks that use powder ingredients use hot water to sell, they may temporarily sell out if a large number of sales occur in a row. This had the disadvantage that sales could decline due to the condition.

In view of the above problems, the present invention provides a control device for a vending machine that can equally sell hot drinks and cold drinks.

Means for Solving the Problems In order to solve the above problems, a control device for a vending machine of the present invention includes a heating device for selling hot drinks, a cooling device and an ice making device for selling cold drinks, A setting means for setting operational priorities of the heating device, the cooling device, and the ice making device; a power source detecting device for detecting that a plurality of power sources are connected to the heating device, the cooling device, and the ice making device; and the power source detecting device. This device is equipped with an operation control unit that controls the operation of the heating device, cooling device, and ice making device regardless of the set priorities of the heating device, cooling device, and ice making device when the device detects multiple power connections. be.

Sakukawa With the above-described configuration, the present invention can simultaneously energize the heating device for selling hot drinks, the cooling device and the ice making device for selling cold drinks, and hot drinks and cold drinks can be sold equally.

EXAMPLE Hereinafter, a control device for a vending machine according to an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a control device for a vending machine according to an embodiment of the present invention. In FIG. 1, 1 is a heating device for selling hot beverages, 2 is a heating device control unit that controls the heating device 1, and 3 is a heating device for selling hot beverages.
4 is a cooling device control unit for selling cold drinks; 4 is a cooling device control unit for controlling the cooling device 3; 5 is an ice making device for selling cold drinks; 6 is an ice making device control unit for controlling the ice making device 6; , 7 are the heating device 1° and the cooling device 3. Setting means 8 sets the priority order of the operation of the ice making device 6, and 8 indicates the heating device 1. The cooling device 3. A power supply detection means 9 detects that a plurality of power supplies are connected to the ice making device 5, and 9 is an operation control unit that is set by the setting means 7 when the power supply detection means 8 detects a plurality of power supply connections. The heating device 1. The cooling device 3. Regardless of the priority order of the ice making device 6, the heating device control section 2.degree., the cooling device control section 4. Controls the ice making device control section 6 and controls the heating device 1. The cooling device 3. The operation of the ice making device 6 is controlled.

The operation of the vending machine control device configured as described above will be described below with reference to the flowchart shown in FIG. 2.
