Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a cooling device for a carbonated beverage dispenser that dispenses a carbonated beverage obtained by diluting and mixing carbonated water and syrup with water.

[Prior art and its problems]

Conventional cooling devices for this type of carbonated beverage dispenser include a cooling section C of a water tank 1 and a cooling section A of a syrup tank 2, as shown in FIGS. 6 and 7.
and the cooling part B of the carbonator 3 are connected by one refrigerant circulation path.The integrated cooler 4 is connected to the condensing unit 6 by piping using a so-called roll bond type in which two aluminum plates are bonded together and a refrigerant passage is formed between the plates. A cooling device is known, and the operation of the cooling device is controlled by a carbonated water temperature controller 11 in a carbonator. For this reason, it is difficult to cool three points, the water in the water supply tank 1, the syrup in the syrup tank, and the carbonated water in the carbonator, to the desired temperature within a predetermined time, and the waiting time for supplying beverages is quite difficult. The drawbacks include that it takes a long time, that the water temperature in the water supply tank on the refrigerant inlet side becomes too cold, and that the temperature of the syrup in the cartridge-type syrup tank increases due to outside air during the initial operation of the device or during a power outage.

[Purpose of the invention]

In view of the above-mentioned drawbacks, this invention provides a carbonated beverage dispenser that can cool the three locations of the water supply tank, syrup tank, and carbonator as needed to shorten the waiting time for beverage supply and suppress the rise in syrup temperature when the beverage is stopped. The purpose is to provide a cooling device.

[Key points of the invention]

The present invention aims to achieve this objective in a cooling device for a carbonated beverage dispenser that supplies a carbonated beverage obtained by diluting and mixing carbonated water and syrup with water. A parallel circuit is formed by a series circuit with a first cooler that cools the carbonated water in the carbonator, and a series circuit with a cooler that cools the carbonated water in the carbonator and a second cooler that cools the syrup in the tank. This is achieved by a cooling system for a carbonated beverage dispenser in which a refrigerant double circuit is constructed by connecting the circuit to a condensing unit consisting of a condenser and a compressor through a capillary tube and a solenoid valve. It is something. In addition, it is preferable that each electromagnetic valve in the parallel circuit is controlled to open and close by detecting the water temperature in the water supply tank and the carbonated water temperature in the carbonator. In addition, the water cooler may be formed by a coil of copper pipe wrapped around the outer circumference of the water tank, and the syrup and carbonated water cooler may be formed integrally with a roll-bond type cooler, or all the coolers may be formed as a single unit. may be formed integrally with a roll bond type cooler having two refrigerant circuits.

[Embodiments of the invention]

The present invention will be described in detail below with reference to drawings showing embodiments of the invention. Figures 1 to 3 are drawings showing an embodiment of the present invention, and in the figures, a cooling coil 5 for cooling water in the tank is fixed in contact with the outer periphery of a stainless steel water tank 1 by soldering. There is. On the other hand, two aluminum plates 4 each have a cooling part A of the syrup tank 2 and a cooling part B of the carbonator 3.
The refrigerant outlet side of the cooling coil 5 is connected by piping in series to the upper part A1 of the syrup cooling part of the roll bond type cooler 4 in which the refrigerant passages 4d are formed between the plates by joining the refrigerant coils 5 and 4c, forming one refrigerant circuit. . The other refrigerant circuit is located at the bottom A of the syrup cooling section.
These parallel circuits are connected through capillary tubes 7a, 7b and solenoid valves 8a, 8b so that the refrigerant flows through the respective refrigerant circuits simultaneously in parallel. The pipes are connected to one condensing unit.
In addition, a water temperature controller 10 is installed in the water supply tank 1.
is provided to detect the water temperature in the tank and activate the solenoid valve 8a.
By closing the refrigerant circuit, the one refrigerant circuit is closed. A water temperature controller 11 is also provided in the other carbonator 3 to detect the carbonated water temperature in the carbonator and close the solenoid valve 8b, thereby closing the other refrigerant circuit. In addition, the water supply tank 1, carbonator 3, and each cooler 4,
Reference numeral 5 is a heat insulating material 9 which is made of urethane foam after being assembled into one piece, and is insulated from the outside air except for necessary parts. Next, FIGS. 4 and 5 show another embodiment of the present invention. In this embodiment, the cooler is from the water supply tank cooling section C to the syrup tank cooling section upper part A1.
This is the same as in the previous embodiment, except that two refrigerant circuits are formed on one roll bond, connecting the syrup tank cooling section A2 and the carbonator cooling section B with another refrigerant circuit. It is the same as the case. When the cooling device is operated with such a configuration, refrigerant can be supplied to each of the three locations, the water supply tank section, the syrup section, and the carbonator section, as needed to cool those sections.

〔Effect of the invention〕

According to this invention, the water supply tank, syrup tank, and carbonator can be cooled as needed, so the standby time for supplying beverages can be shortened, and furthermore, it is possible to suppress the increase in syrup temperature even when the cooling device is stopped.
