Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for supplying ice-containing diluted water to be mixed with syrup and carbonated water in a carbonated beverage manufacturing apparatus.

In particular, in vending machines called dispensers, when a customer performs a predetermined vending operation, carbonated water,
The syrup and diluent water are mixed to produce a carbonated beverage, which poses a significant hygiene problem.

In other words, syrup and carbonated water have a bacteriostatic effect, but dechlorinated dilution water remains and circulates inside the vending machine, which often causes bacterial growth1.Therefore, the dilution water supply device is It is necessary to clean it regularly, but in the past, this was done manually, so it was not possible to do it that many times.

Currently, ice making machines are not cleaned at all.

From this point of view, the present invention provides a pipe switching device such as a four-way valve, and is configured to be able to switch the pipe connection between the first state and the second state, and when in the first state, normal supply operation is performed. The purpose of the present invention is to present a device that can perform the following operations, automatically perform a cleaning operation inside the device, and, when in the second state, can perform the cleaning operation of the ice maker.

One embodiment will be described in detail below with reference to the drawings.

FIG. 1 shows the dilution water supply path containing ice according to the present invention.

Tap water supplied to this device flows into a filter 7 via an inlet solenoid valve 6, and after being dechlorinated, is retained in a container 1 as dilution water.

The container 1 has a first hole 11 and a second hole connected to the ice maker 2.
There is a hole 12, and the dilution water flowing out from the first hole 11 via the four-way valve 5 is piped so as to flow into the ice maker 2.

The dilution water flowing into the cooling cylinder 21 is made into ice and stored in the water storage chamber 22.

At this time, piping is provided so that the molten liquid of the stored water flows into the container 1 through the second hole 12.

On the other hand, in order to drain the dilution water out of the machine, the dilution water in the container 1 is pumped out by the pump 3, introduced into the cooling device 4 by the four-way valve 5, cooled, and then flows out from the dilution water solenoid valve 8.

If the dilution water is discharged from the dilution water solenoid valve 8 and the ice from the water storage chamber 22 is also discharged at the same time, dilution water containing ice can be supplied.

In this configuration, the present invention is characterized in that the pump 3 is operated even when dilution water is not being supplied outside the machine, and the four-way valve 5 creates the 4i state and the second state in the piping connection. .

When the four-way valve 5 is in the first state shown in FIG.
That is, when the dilution water pipe 9 is connected to the cooling device 4 via the four-way valve 5 and the first hole 11 is connected to the ice maker 2, the dilution water is removed by opening the dilution water solenoid valve 8 described above. Supply to the outside of the machine and ice making operation of the ice making machine 2 are performed.

Further, when the dilution water solenoid valve 8 is closed, the pressurized and cooled dilution water is constantly circulating from the container 1 to the pump 3 to the four-way valve 5 to the cooling device 4 to the container 1. A bacteriostatic action takes place.

When the four-way valve 5 is in the second state shown in FIG. 3, that is, when the dilution water pipe 9 is connected to the ice maker 2 via the four-way valve 5, the ice maker is in a cleaning cycle.

In this state, the cleaning liquid dissolved in the container 1 and pressurized by the pump 3 circulates in the order of the four-way valve 5 → the ice maker 2 → the container 1 → the pump 3, so that the ice maker 2 can be cleaned.

Thereafter, the cleaning liquid may be drained using the drain electromagnetic valve 10 and tap water may be replenished into the container 1 to bring the four-way valve 5 into the first state.

In the case of a cleaning cycle as described above, the pressurized water from the pump 3 does not go to the cooling device 4, so that wasteful release of heat in the cooling device 4 is prevented.

That is, the cooling device 4 connects a dilution water pipe 9 to a cooling water tank 41 containing ice.
The cleaning liquid, which is piped in a coil shape and is not discharged as dilution water, will not pass through the cooling water tank 41 and emit heat unnecessarily, thereby preventing the temperature of the cooling water tank 41 from increasing.

The present invention described in detail above is characterized by the provision of a device that keeps the dilution water pump always in operation and can switch the piping connection between the first and second states, such as a four-way valve.

In the first state, the dilution water can flow out of the machine when necessary, that is, when it is supplied, and a bacteriostatic effect is always performed in the dilution water circulation circuit excluding the ice maker to maintain cleanliness. .

By switching the four-way valve to the second state, the ice maker can be easily cleaned.

Moreover, since the cleaning liquid does not pass through a cooling device, heat loss due to cleaning can be prevented, and cooled dilution water can be supplied even after cleaning is completed.
