Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a beverage liquid cooling device for cooling beverage liquids, such as coffee, black tea, tea, etc., using tap water.

[Conventional technology]

A typical conventional beverage liquid cooling device of this type will be explained with reference to FIG. A cold water tank 1 is insulated with a heat insulating material 2, has a box shape, and stores cooling water 3 inside. This cooling water 3
is cooled by an evaporator 5 connected to a refrigerator 4, and ice 6 is accumulated around the evaporator 5. The amount of water stored is controlled by a water amount detection element 7. At approximately the center of the cold water tank 1, there is provided a circular stepped liquid storage tank 8 with a large top and a small bottom, a discharge pipe 9 is connected to the bottom, and a spout cock IO is provided at the tip of the tank 8. . The upper part of the liquid storage tank 8 is open to the upper part of the cold water tank 1, and the upper surface is covered with a lid It. In addition, an air pipe 1 is installed in the center of the step part of the liquid storage tank 8.
A conical beverage receiving plate 13 with a slightly lowered circumference is mounted. A plurality of small holes 14 are provided on the outer periphery of this beverage receiving plate 13. Still, a stirring blade 16 driven by an electric motor 15 is provided at the bottom of the inner center of the cold water tank l.

Next, the operation will be explained. With ice accumulated around the evaporator, the stirring blade 16 is rotated to remove the lid 1 at the top of the liquid storage tank 8.
1 and supplies hot beverage liquid 17.

Beverage liquid 17 is passed through small holes 14 provided on the outer periphery of beverage receiving plate 13.
The liquid flows down to the step part of the liquid storage tank 8, and then flows in layers along the inner wall of the liquid storage tank 8, which is cooled by the cooling water 3, and is cooled and stored in the lower part. If this state is maintained, the beverage liquid will be further cooled. Then, by opening the pouring cock 10 as necessary, the cooled beverage liquid 17 can be poured out.

Ice 6 is accumulated around the evaporator 5. When a large amount of high-temperature beverage α-form 17 is supplied to the storage tank 8, the ice 6 absorbs heat as heat of fusion until the ice 6 melts, and the cooling water 3 does not rise in temperature.

On the other hand, when the ice 6 begins to melt, the water amount detection element 7 is activated, and the refrigeration unit 4 is activated in response to the signal to cause ice to form around the evaporator 5. However, if the high-temperature beverage liquid 17 is continuously supplied even after the ice 6 has finished melting, the refrigerating capacity will exceed the refrigerating capacity of the refrigerating unit (UNINO)-1, and the temperature of the cooling water 3 will rapidly rise, resulting in insufficient cooling capacity.

[Problem to be solved by the invention]

In the above-mentioned beverage liquid dispensing device, the amount of beverage liquid 17 that can be cooled is limited depending on the amount of water stored. That is, once the ice 6 has finished melting, the temperature of the cooling water 3 is rapidly raised, and the cooling capacity is greatly reduced. After the ice 6 has melted, it is impossible to use it continuously. Furthermore, the refrigeration unit 4 is required, making the device larger and more expensive, and it becomes unusable in the event of a power outage or breakdown. In addition, considering the ice storage time, the refrigeration unit 4
You must turn on the power and make preparations.

Furthermore, if the device is left unused for a long time, it wastes electricity and is uneconomical.

In addition to these, the beverage liquid 17 provided at restaurants is often provided in a container with ice, and it is necessary to cool it down to the point where it must be cooled using this type of cooling device. There are many problems such as being uneconomical and wasteful.

The present invention was made to solve these problems.
The object of the present invention is to provide a compact and inexpensive beverage liquid cooling device that can cool beverage liquids as long as there is a tap water source, is less likely to malfunction, and does not require preparation.

[Failure to solve the problem]

The present invention has a dispensing cock at the bottom, a large diameter at the top and a small diameter at the bottom via a step, and a night tank which is placed in the step of the liquid storage tank and supplies the liquid. The beverage receiving plate, which has multiple drainage holes on its outer periphery, is separated from the outer wall of the liquid storage tank for a certain period of time, and a waterway is created by surrounding the outer wall of the liquid storage tank. It consists of a cold water tank, an inlet pipe that is installed in the cold water tank and connects to the waterway between the liquid storage tank and the cold water tank to introduce tap water, and a Saturday pipe that discharges tap water. This is a beverage liquid cooling device that introduces water, cools the outer wall of a liquid storage tank by letting tap water flow through a waterway, and cools the beverage liquid flowing down along the inner wall of the liquid storage tank.

A beverage detection element is still installed in the large diameter part of the liquid storage tank, and a valve device to introduce and stop tap water is installed in the inlet pipe.The valve device opens in response to a signal from the beverage detection element to allow tap water to flow into the waterway and into the liquid storage tank. This is a beverage liquid cooling device that cools the outer wall of a storage tank and cools the beverage liquid flowing down along the inner wall of a liquid storage tank.

Furthermore, we installed a beverage detection element in the large diameter part of the liquid storage tank, a valve device to introduce and stop tap water into the inlet pipe, and a timer to adjust the introduction time of tap water. This is a beverage liquid cooling device that starts a timer in response to a signal, causes tap water to flow through a water channel for a time set by the timer, cools the outer wall of the liquid storage tank, and cools the beverage liquid flowing down along the inner wall of the liquid storage tank.

It would be more effective if water passages were provided with water guides so that the tap water would flow evenly around the outer wall of the liquid storage tank of these beverage liquid cooling devices.
