Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carbonated water producing apparatus and a carbonator structure thereof.

[0002]

[Prior Art]

 In the conventional carbonated water manufacturing apparatus, as shown in an example in FIG. 4, a refrigerant is supplied from a cooling device (not shown) to a refrigerant pipe 2 installed in the ice bank 1, and the refrigerant cools the water in the ice bank 1. As a result, ice blocks 3 are formed around the refrigerant pipe 2. On the other hand, the water in the ice bank 1 is agitated by the propeller 5 driven by the motor 4 to become cooling water, which cools the carbonator 6 and the cooling pipe 7 swirled around the carbonator 6.

When producing carbonated water in the carbonator 6, the higher the internal carbon dioxide gas pressure and the lower the water temperature, the better. Therefore, the carbon dioxide gas cylinder 8 to the pressure regulating valve 9, the gas pipe 10 and the check valve 11 are used. While carbon dioxide gas pressure of about 5 kg / cm 2 (0.49 MPa) is constantly applied to the inside of the carbonator 6 through the above, the carbonated water in the carbonator 6 is cooled by the cooling water from the peripheral surface of the carbonator 6. When the water level in the carbonator 6 becomes lower than a predetermined level, the water supply pump 12 operates and the water supply valve 13 opens, so that the water supply pressurized by the water supply pump 12 is cooled while flowing through the cooling pipe 7, and the water supply pipe 14 and the reverse pipe. Carbonated water is produced by being supplied into the carbonator 6 through the stop valve 15.

The low-temperature carbonated water in the carbonator 6 can be extracted from the extraction pipe 17 by opening the extraction valve 16, and a cold water pipe 18 is connected to the water supply pipe 14 to cool the cold water valve 19. When opened, cold water can be taken out by operating the water supply pump 12.

However, in the above-mentioned carbonated water producing apparatus, since the inside of the carbonator 6 is high in pressure, it is necessary to increase the pressing force of the water supply pump 12 further, and further, the water supplied to the inside of the carbonator 6 and the carbonator 6 In order to increase the contact area with the carbon dioxide gas inside, the water supply is sprayed into the carbonator 6 from a water spray nozzle (not shown), so the pressure of the water supply pump 12 must be further increased.

[0006] Therefore, the water supply pump 12 and its pipes are expensive and troubles are likely to occur, and moreover, the installation space is required, and the size of the entire apparatus is not only increased. However, there was a drawback that a lot of noise was easily generated. In addition, when water is supplied to the inside of the carbonator 6 by the water supply pump 12, the check valve 11 of the gas pipe 10 is indispensable because the pressure inside the carbonator 6 is temporarily increased. Since the pressure in the water supply pipe 14 is lower than that in the carbonator 6 except when water is being supplied, the check valve 15 of the water supply pipe 14 is somewhat indispensable, and the cost of the device is high in this respect as well.

[0007]

[Problems to be solved by the device]

 Therefore, the present invention is intended to reduce the manufacturing cost and ensure smooth operation of the carbonated water manufacturing apparatus with a simple structure.

[0008]

[Means for Solving the Problems]

 In order to solve the above problems, a carbonated water production apparatus according to the present invention is a carbonator cooled by cooling water in an ice bank, a gas pipe for supplying pressurized carbon dioxide gas to the carbonator, and a gas provided in the gas pipe. A supply valve, a water supply pipe extending from the cooling pipe in the ice bank into the carbonator, a water supply valve provided in the water supply pipe, an exhaust pipe having one end opened in the carbonator and the other end extending outward, It has an exhaust valve provided in the exhaust pipe and an extraction pipe with one end open to the carbonated water in the carbonator and the other end extending outward, and when the water supply valve is opened, the gas supply valve is closed and the exhaust valve is opened. It is configured to open.

【Example】

 Hereinafter, the embodiment shown in the drawings will be specifically described by giving the same reference numerals to the same portions as the above embodiment. In FIG. 1, a gas supply valve 20 is provided in a gas pipe 10 extending from a carbon dioxide gas cylinder 8 through a pressure adjusting valve 9 into the carbonator 6, and the gas pipe 10 is further in a horizontal direction below the carbonator 6. The carbon dioxide gas of fine bubbles can be appropriately discharged into the carbonated water 21 in the carbonator 6 through a large number of small holes provided in this portion.

The water supplied from the outside makeup water pipe 22 to the cooling pipe 7 in the carbonator 6 is cooled by the cooling pipe 7, and then passes through the water supply valve 23 provided in the water supply pipe 14 to make the carbonator 6 The water level in the carbonator 6 is detected by the detection switch 24. The extraction pipe 17 has one end opened to the carbonated water at the bottom of the carbonator 6, and a partition plate 25 provided between the extraction pipe 17 and the gas pipe 10 extracts fine bubbles of the carbon dioxide gas emitted from the gas pipe 10. It is designed not to be sucked into the pipe 17. An exhaust valve 27 is provided in an exhaust pipe 26 having one end opened at the top of the carbonator 6, and the other end of the exhaust pipe 26 communicates with the outside air through a throttle or the like not shown.

In the above carbonated water producing apparatus, when the water level in the carbonator 6 is sufficiently high, as shown in the control circuit diagram of FIG. 2, the upper switch 30 and the lower switch 31 of the detection switch 24 are closed. Then, the relay X1 is excited, and the relay X1 is self-held by its contact point X11. When the relay X1 is excited, its contact X14 is opened and the water supply valve 23 and the exhaust valve 27 are closed to prevent water supply into the carbonator 6 and exhaust from the carbonator 6, and the contact X13 is closed to close the gas. The supply valve 20 is opened, and carbon dioxide gas is supplied from the carbon dioxide gas cylinder 8 to the water in the carbonator 6.

Next, when the extraction valve 16 is opened and carbonated water is extracted outward from the inside of the carbonator 6 through the extraction pipe 17 and the water level of the carbonated water 21 inside the carbonator 6 drops, first, the detection switch 24 The upper switch 30 opens. When the carbonated water 21 is further extracted and the water level drops to a certain level, the lower switch 31 is also opened, the self-holding of the relay X1 is also released, and the relay X1 is demagnetized. Therefore, the contact X13 is opened and the gas supply valve 20 is closed, the supply of carbon dioxide gas from the carbon dioxide cylinder 8 into the carbonator 6 is stopped, and the contact X14 is closed and the water supply valve 23 and the exhaust valve 27 are opened, and the carbonator is closed. Water is supplied to the inside of the 6 and exhaust from the inside of the carbonator 6 is performed. At this time, the carbon dioxide gas pressure is released from the inside of the carbonator 6 and the pressure is almost atmospheric pressure. Therefore, the water can be supplied from the makeup water pipe 22 at a normal water pipe pressure.

Next, when the water level in the carbonator 6 rises due to the water supply from the makeup water pipe 22, the lower switch 31 of the detection switch 24 is first closed. When the water level in the carbonator 6 becomes sufficiently high as the supply is further continued, the upper switch 30 is also closed and the relay X1 is excited, so that the contact X14 is opened and the water supply valve 23 and the exhaust valve 27 are opened in the same manner as described above. When closed, water supply to the carbonator 6 and exhaust from the carbonator 6 are blocked, the contact X13 is closed and the gas supply valve 20 is opened, and carbon dioxide gas is supplied from the carbon dioxide gas bomb 8 to the water in the carbonator 6. As a result, carbonated water is produced in the carbonator 6.

In the above device, when the water is supplied to the carbon dioxide 6, the exhaust valve 27 is opened so that the inside of the carbon dioxide 6 is almost at atmospheric pressure. Therefore, the conventional high pressure pump for water supply is not required at all. At the same time, the manufacturing cost of the device can be significantly reduced, and at the same time, the installation place of the device can be reduced, and the noise generated by moving parts such as the high-pressure pump is reduced. Further, in the above-mentioned device, when water is supplied to the inside of the carbonator 6, the exhaust valve 27 is opened so that the inside of the carbonator 6 becomes almost atmospheric pressure. Therefore, the check valve which has been conventionally required becomes unnecessary. Also from this point, the manufacturing cost of the device can be reduced.

FIG. 3 shows a modified example of the control circuit, in which a timer 33 is provided in parallel with the circuits of the water supply valve 23 and the exhaust valve 27, and a switch 34 opened and closed by the timer 33 is provided in the circuit of the water supply valve 23. After installation, the exhaust valve 27 is opened in the same manner as in FIG. 2 and then the switch 34 is closed after the time set by the timer 33 has passed to reduce the carbon dioxide gas pressure in the carbonator 6 and then the water supply valve. By opening 23, carbon dioxide is prevented from flowing into the water supply side.
