Description

[Detailed Description of the Invention] The present invention relates to a beverage vending machine with an ice making device that automatically dispenses drinking water and ice cubes made in advance by an ice making device into a cup each time the drink is sold.

By the way, if you look at this type of vending machine, you will notice that the water tank that stores water supplied from the water supply system is not designed to take into account the ambient temperature, and is connected to the ice making device. When the ambient temperature rises and the water temperature in the water supply tank rises, the ice making apparatus takes a long time to make, making continuous sales impossible or having a negative effect on the lifespan of the ice making apparatus itself.

The present invention was devised in view of the drawbacks of conventional vending machines, and aims to solve the drawbacks of the conventional vending machines by cooling the water in the water tank.

Hereinafter, one embodiment will be described in detail with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a water supply tank, and its outer surface is provided with a winding cooling pipe 2 constituting a cooler during the first cooling cycle, and both cooling pipes 2 are covered with a heat insulating material 3.

This first cooling cycle is well known and consists of the cooling pipe 2, a compressor, a condenser, a capillary tube, etc. In this embodiment, these elements are housed in the case 4 for convenience. do.

Reference numeral 5 designates a water supply electromagnetic valve interposed in a pipe 8 connecting the circulation vibro and the water supply, and in response to opening/closing of a micro switch 10 controlled by a float 9 that detects the water level in the water supply tank 1, water is supplied from the water supply. The ice is supplied to the water tank 1 or the supply is stopped.

Numeral 11 is a blade that stirs the water in the water supply tank 1, and is driven by a stirring motor 12.

13 is a first water temperature controller which detects the water temperature in the water supply tank 1 with the temperature sensor 14, and controls the compressor of the first cooling cycle based on the result to control the water temperature in the water supply tank 1. ing.

Now, regarding the above-mentioned circulating vibro, this is water tank 1.
It is led out from the bottom surface of the water supply tank 1 and reaches the top surface of the water supply tank 1 again.A valve 7 is provided in the middle of the management, and a heat insulating material 19 is provided on the outer surface of the pipe between this valve and the water supply tank 1, and a pump 16 is provided. A first branch pipe 17 is led out between the pump 16 and the water supply tank 1, and a second branch pipe 18 is led out between the pump 16 and the valve 15.

Reference numeral 20 denotes an ice making device, which is already well known, so a detailed explanation thereof will be omitted, but it is roughly divided into a drive section 21, an ice making section 22, and an ice storage section 23.

The ice-making unit 22 is equipped with a cooling pipe 25 wound around the outer wall surface, which constitutes a cooler during the second cooling cycle. An ice feeder 26 is installed upright in the center and is driven and rotated by the drive unit 21 to scrape off the ice layer formed on the inner wall surface of the ice making cylinder 24 with a spiral wire 27 provided on the outer periphery and send it to the ice storage unit 23. The water storage section 23 is connected to a water storage chamber 28 which is provided in communication with the ice making cylinder 24 and has an outlet 29, and a water storage chamber 28 which is connected to the upper end of the ice feeder 26 and rotates together with the ice feeder 26. The agitator 30 prevents the ice fed from the ice making tube 24 from adhering to the ice making tube 24.

Reference numeral 31 denotes a chute that guides the ice block F carried out from the outlet 29 to the cup C carried out to the sales outlet.

32 is a mixer, and the raw material tank 3 located above
By opening the electromagnetic valve 34 provided in the second branch pipe 18, the beverage raw material inputted from 3 is diluted and mixed with cold water supplied from the circulating vibro to make drinking water, and the ice block F is inputted from the supply nozzle 35. Pour into cup C.

36 is a second water temperature controller attached to the outer wall surface of the circulation vibro, and detects the water temperature inside the circulation vibro with the temperature sensor 37. As a result, if the water temperature is high, , gives a signal to the circulation pump 16 to drive it, and operates to replace the water in the circulation vibro with the cold water in the water supply tank 1.

Therefore, when the water temperature in the vibro reaches a predetermined temperature, the driving of the circulation pump 16 is stopped.

The second cooling cycle is also a well-known cooling cycle, and consists of a compressor, a condenser, a capillary tube, etc. in addition to the cooling pipe 25, and in this embodiment, these are not included. These elements are placed in the case 38 for convenience.

The present invention is constructed as described above, and its operation will be explained below.

Under normal operating conditions, a portion of the cold water discharged from the water supply tank 1 to the circulating vibro is sent to the ice making section 22 of the ice making device 20 through the circulating vibro and the first branch pipe 17, where it is turned into ice and stored in the water storage section 23. At the same time, each time the ice cubes are sold, they are carried out as ice cubes F through the outlet 29 and put into a cup C.

In addition, the remaining cold water is pumped into the mixer 3 by driving the circulation pump 16 and opening the solenoid valve 34 every time there is a sales signal.
Here, it is mixed with beverage raw materials inputted from the raw material tank 33 to become predetermined drinking water, which is then supplied to the cup C into which the ice block F is loaded and sold.

In such a normal operating state, when the water level in the water supply tank 1 falls, the water supply solenoid valve 5 is opened by the operation of the float 9 and the microswitch 10, and tap water is supplied into the water supply tank 1.

Also, the water temperature in the water supply tank 1 is controlled by a first water temperature controller 13.
By controlling the drive of the compressor during the first cooling cycle by the detection operation, a predetermined temperature is always maintained.

Furthermore, if the water temperature in the circulating vibro is higher than a predetermined value due to reasons such as no sales operation being performed for a long period of time, the second water temperature controller 36 operates to drive the circulation pump 16 to remove the ice in the circulating vibro and the water tank. Replace the cold water in 1 and always keep the ice temperature in the circulating vibro at the specified value.

Of course, when the water temperature in the circulation vibro reaches a predetermined value, the second water temperature controller 36 stops driving the circulation pump 16.

In addition, in the above-mentioned embodiment of the present invention, the water supply tank 1 and the ice making device 2 are
However, the present invention is not limited to this, and only one of the cooling cycles is provided, and the cooling pipe of such cooling cycle is divided into two to connect the water supply tank 1 and the ice making device. May be applied to

The present invention, as shown in Narukami, sends water from the water supply tank to an ice making device to make ice cubes, and each time the ice cubes are sold, they are put into a cup or the like together with drinking water made by diluting beverage ingredients formed in a separate mixer. The water supply tank is equipped with a cooler, and the water supply tank is provided with a circulation pipe that is led out from the water supply tank and returns to the water supply tank again, and this circulation pipe is driven when a sales signal is received. a circulation pump that circulates water; a water supply device that supplies the water in the circulation pipe to the mixer as water for diluting beverage raw materials; Since we provide a beverage vending machine with an ice making device that is equipped with a water temperature controller that drives the pump, the water that dilutes the beverage ingredients becomes colder, and the amount of ice cubes that are taken out can be reduced, reducing the capacity of the ice making device. can be made smaller, and continuous sales ability can be improved.

Furthermore, when the water temperature in the circulation pipe rises, the circulation pump is driven to replace the water with the cold water in the water supply tank, which not only promotes the above-mentioned effects, but also prevents the water from spoiling in the circulation pipe. Therefore, it is an excellent idea that can make the vending machine more sanitary when the mixer etc. are washed with the water in the circulation pipe.
