Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup-type beverage vending machine for hot beverages, and more particularly to a device for adjusting the temperature inside the machine.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram of a conventional cup type beverage vending machine. In FIG. 3, hot beverage raw material 1
00, 101, 102, 103, 104 are selected according to customer's request at the time of sale and agitators 200, 201, 202 are selected.
Is cut into a certain amount, diluted with warm water therein, and poured into the drinking cup 9. Hot water for hot beverages is prepared by heating tap water with a heater in the hot water tank 10 and stored. Since the internal temperature of the vending machine becomes high due to the heat from the hot water tank or the like, it is ventilated by the ventilation fan 3, but is 5 ° C. to 10 ° C. higher than the ambient temperature.

Since the temperature inside the machine decreases from mid autumn to mid spring when the ambient temperature decreases, a heater 8 is provided in the middle of the pipe from the stirrer to the cup 9 to prevent the temperature of the beverage from decreasing. Reference numeral 21 is a switch that connects the ventilation fan 3 and the power supply, and 51 is a switch that connects the heater 8 and the power supply.

[0004]

In the above-mentioned vending machine, when selling a hot beverage in the winter when the ambient temperature is low, the pipe from the hot water tank to the stirrer and the pipe from the stirrer to the cup have the same temperature inside the machine. Since it is assimilated, there is a problem that the temperature of the hot beverage is lowered particularly when it is sold intermittently. Therefore, a heater 8 is provided in the middle of the pipe to compensate for the temperature decrease. There is a problem of forgetting to switch the on / off switch 51 of the heater 8 because the service person who collects the sales proceeds and replenishes the raw materials is performing.

Further, since the in-flight ventilation fan is left open all year round, there is a problem that hot air in the air is exhausted from mid autumn to mid spring, and as a result, outside air is taken into the air and the temperature inside the air is further lowered. . An object of the present invention is to provide a cup-type beverage vending machine that prevents a decrease in the ambient temperature in the machine from a predetermined date and time in the middle of autumn and reduces the temperature drop of hot beverages.

[0006]

According to a first aspect of the present invention, a stirrer for mixing the ingredients of a hot beverage with hot water, a heater for heating the beverage mixed with the hot water, and a date and time are provided on the front of the vending machine. A computer calendar for displaying,
In a vending machine equipped with a control device that controls the operation of the vending machine, a ventilation fan that ventilates the inside of the machine, and an on / off switch for the fan, ventilation is performed according to the date and time stored in the computer calendar for displaying the date and time. It will be a beverage vending machine that turns fans on and off.

According to a second aspect of the present invention, in the vending machine according to the first aspect, a beverage after the ventilation fan is turned on and the hot water is mixed according to the date and time stored in the computer calendar for displaying the date and time. A beverage vending machine in which the heater for heating is turned off, the ventilation fan is turned off, and the heater is turned on.

[0008]

[Function] The ventilation fan inside the machine exhausts the air inside the machine to the outside,
As a result, the inside of the machine becomes a negative pressure and the outside air is taken into the machine, so that the air inside the machine is ventilated. Therefore, from mid autumn to mid spring when the ambient temperature is low, the temperature inside the machine does not drop much unless the ventilation fan is stopped to ventilate the room. Therefore, the temperature drop in the piping from the hot water tank to the cup decreases. Furthermore, during this period, a heater is wrapped around the pipe from the stirrer to the cup to keep the temperature of the pipe from 30 ° C to 60 ° C.
If it is heated to an appropriate temperature in the range of ° C, the temperature difference between the beverage passing through the pipe and the pipe material is reduced, and the temperature drop of the beverage is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram of the essential parts of an embodiment of the present invention. In FIG. 1, members given the same reference numerals as those in the conventional example have approximately the same functions, and therefore their explanations are omitted. In FIG. 1, when the customer selects his / her favorite beverage, the beverage raw material is mixed with warm water and poured into the cup according to a command from the control device 1. The ventilation fan 3 serves to prevent the temperature inside the vending machine from rising due to heat radiation from a device (not shown) inside the vending machine. The fan on / off switch 2 is a switch for connecting / disconnecting the ventilation fan 3 to / from the power source.

The computer calendar 4 is used to display the date and time on the vending machine. Further, the date and time can be input from a ten-key pad (not shown), and when the designated date and time is reached, the output can be output to the control device. In such a configuration, the computer calendar 4 outputs to the control device 1 when the date and time input from the ten-key pad (not shown) comes, and when the date and time is in the middle of autumn, the fan on / off switch 2 is turned off to turn on the ventilation fan. Stop.

If the date and time is in the middle of spring, the fan on / off switch 2 is turned on to operate the ventilation fan. FIG. 2 is a block diagram of the essential parts of another embodiment of the invention.
2 is different from FIG. 1 in that the heater 8 wound around the pipe 6 of the stirrer 20 and the cup 9 for mixing the beverage raw material with the hot water.
This is to turn on / off the heater on / off switch 5 for turning on / off according to the set date and time of the computer calendar 4.

In FIG. 2, the computer calendar 4 outputs to the control device 1 when the date and time input from the ten-key pad (not shown) comes, and when the date and time is in the middle of autumn, the fan on / off switch 2 is turned off. Then, the ventilation fan is stopped, and the heater ON / OFF switch 5 is turned ON so that the heater 8 wound around the pipe 6 is turned ON.
If the date and time is in the middle of spring, the fan on / off switch 2 is turned on to operate the ventilation fan, and the heater on / off switch 5 is turned off to turn off the heater 8 wound around the pipe 6.

The present invention may be used in cup and beverage vending machines for hot and cold beverages.

[0014]

According to the present invention, the ventilation fan is stopped during a period when the ambient temperature preset in the computer calendar is low to prevent the temperature inside the machine from dropping, and the pipe from the agitator of the beverage material to the cup is connected. Since it is heated by the heater, there is an effect that a hot beverage having a small temperature drop can be provided even when the ambient temperature is low.

Further, since the heater is turned off during the period when the ambient temperature is high, there is an energy saving effect.
