Description

[Detailed Description of the Invention] The present invention relates to a beverage vending machine that mixes and sells diluted water, syrup, and carbonated water.

In the above-mentioned vending machine, the present invention houses a liquid circuit consisting of a distiller, a pressure pump, a syrup container, a carbonator, etc., and a connection line connecting them together in an insulated box, and uses cold air from a cooler to It is an object of the present invention to efficiently cool a distern and to cool the distern so that its inlet/outlet pipe and water level control part do not freeze.

An embodiment of the present invention will be described in detail below based on the drawings.

The present embodiment will be explained by taking as an example a Bostmix type beverage vending machine that supplies carbonated water and syrup under pressure using the pressure of carbon dioxide gas, mixes the carbonated water and syrup after the supply valve, and delivers the carbonated beverage.

1 is a vending machine main body, and a heat insulating material 3 is inserted between an outer box 2 and an inner box 4.

Reference numeral 5 denotes a partition wall that separates a storage chamber 6 for storing a liquid circuit from a cold air machine room 7, and a compression chamber 8, a condenser 9, and an electric blower 10 for the condenser are housed in the machine room T. has been done.

11 closes the front surface of the main body 1 and also closes the storage chamber 6.
This is a front door with a heat insulating material 12 inserted into the surface corresponding to the front door.

On the other hand, water from the water supply pipe 13 is controlled by an on-off valve 14 and stored in a certain amount in a gas tank 15 made of a material such as stainless steel, which is open at the top and in contact with the atmosphere.

That is, due to the vertical movement of the ball 16 and its arm 16a due to the increase or decrease of water in the register 15, for example, when the lower water level detection switch 17 is activated, the on-off valve 14 is opened, and when the upper water level detection switch 18□ is activated, the on-off valve 14 is opened. is closed, and a certain amount of water is always stored in the bismenine 15.

The outlet pipe 15a of the distern 15 is connected to a pressurizing pump 19, and the pump pressurizes the water from the distern 15.

A carbonator 20 introduces carbon dioxide gas from a gas cylinder (not shown), and also introduces pressurized water from a pump 19 and mixes the two to produce carbonated water.

21 is a syrup container, and the syrup is also pressurized by the pressure of carbon dioxide gas in the cylinder.

The inlet pipe/outlet pipe 15a of the above-mentioned distern 15 and the above-mentioned water level control section are provided with a continuous box body 22 made of, for example, stainless steel, so that the cold air from the cooler 23 does not hit directly. Hold and store.

An opening 25 is formed in the side wall of the continuous box body 22 so that cold air produced by the cooler 23 is blown into the box body 22 by a cooler electric blower 24, and an opening 25 is also formed in the ceiling wall. Box body 22
A circulation opening 26 is provided so that the cold air blown inside can be circulated within the storage chamber 6.

Note that the continuous box body 22 may be formed of a heat insulating wall, and the cooler electric blower 24 may be provided on the side wall.

Reference numeral 27 is a sales port provided on the front door 11, and the supply valve 2
A cup 28 is placed thereon which receives beverages from each nozzle 30 controlled by 9, and is supplied to a customer.

Due to the above structure, when diluting water, syrup, and carbonated water are mixed and sold, the diluting water is generally required to be about 5 times more than the syrup, so the water in the distiller becomes close to ice. If it is cooled in the old days, it will be possible to provide high quality beverages, and the cold air from the cooler will not directly hit the inlet/outlet pipes and water level control parts of the distiller, allowing them to be cooled efficiently without freezing. be able to.

In addition, it is possible to cool down the liquid circuit that is affected by the distern, pressure pump, syrup container, carbonator, etc., and their connection lines, so the distern and syrup containers are not completely airtight containers, but are open and the liquid inside is exposed to the atmosphere. Bacteria will not grow even if it comes into contact with

Claims (1)

[Scope of utility model registration request] In a beverage vending machine that mixes and sells diluted water, syrup, and carbonated water, the liquid circuit connected to the distiller, pressure pump, syrup container, carbonator, etc., and the connection line that connects these are housed in an insulated box. The distern is housed in a shielding box that shields the inlet/outlet pipe of the distern and the water level control section provided at the top of the distern so that the cold air from the cooler does not directly hit, and the distern is cooled in the shielding box. A beverage vending machine, characterized in that a circulation opening is formed to take in cold air from the vending machine and to circulate the cold air within the heat insulating box.
