Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a tea supply device arranged in a tea service area.

[Prior Art] In general, a free tea service area is arranged in a venue where a large number of people gather, such as a venue for a national sports competition or a venue for a tree-planting festival.

Since the above-mentioned service office is specially installed outdoors, a kettle or a pot filled with tea is usually installed so that the user can freely drink by self-service.

[Problems to be solved by the device]

By the way, at a service place that uses containers such as kettles and kettles, it is necessary to anticipate the number of visitors to the venue and install the number of containers that matches the number of visitors. It is necessary to constantly monitor the presence or absence of tea inside and to replenish it each time it becomes empty or in small quantities, so there is the inconvenience of requiring several managers.

In general, hot tea can be easily formed by pouring hot water into a container containing tea leaves, but cold tea requires a great deal of time because it is necessary to cool the hot tea. For this reason, the tea service office normally provides only hot tea, and there is a disadvantage that the number of users is small during the hot summer months and the utility value of the service office is impaired.

Then, this invention makes it a technical subject to solve the above-mentioned inconvenience and to provide a small tea supply device which can provide two types of tea, hot tea and cold tea, and which is easy to manage.

[Means for Solving the Problems]

In order to solve the above problems, in the present invention, a water heater that uses propane gas as a fuel and a hot water storage tank that stores hot water discharged from the water heater are provided, and the inside of the hot water storage tank is porous. Incorporate a tea strainer, connect at least two tea outlet pipes to the bottom of the hot water storage tank, attach a hot tea outlet opening / closing plug to the tip of one of the discharge pipes, and install the other discharge pipe below the hot water storage tank. The pipe is installed in a cooling tank into which a cooling medium is supplied, and an opening / closing plug for taking out cold tea is attached to the tip of the other taking-out pipe taken out of the cooling tank to the outside of the tank.

[Action]

With the above configuration, tea can be formed in the hot water storage tank by putting tea leaves in the tea strainer and pouring hot water into it. Hot tea can be taken out. Also, the hot tea in the hot water storage tank flows into the take-out pipe installed in the cooling tank and is cooled by exchanging heat with the cooling medium supplied into the cooling tank. By doing
You can get cold tea.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the drawing, the hot water storage tank 1 has a lid 2 that can be opened and closed at the top, and a supply port 3 formed in the lid 2 is opened and closed by a cap 4.

A hot water outlet pipe 6 of a hot water storage type water heater (water heater) 5 that uses propane gas as a fuel is arranged on the supply port 3. A valve 7 is attached to the hot water outlet pipe 6, and by opening the valve 7, hot water is supplied from the hot water outlet pipe 6 through the supply port 3 into the hot water storage tank 1.

A porous tea strainer 8 formed of a net or the like is incorporated in the hot water storage tank 1, and a flange 9 provided on an upper peripheral edge of the tea strainer 8 is supported by a peripheral edge of an opening portion of the hot water storage tank 1.

The hot water storage tank 1 is preferably made of a heat insulating material in order to store a required amount of tea therein.

Two tea extraction pipes 10 and 11 are connected to the bottom of the hot water storage tank 1, and one tea extraction pipe 10 is piped inside a cover 12 which supports the hot water storage tank 1, and a front plate 13 of the cover 12. It is connected to the open / close plug 14 for taking out hot tea attached to.

The other tea take-out pipe 11 is piped in a cooling tank 15 provided inside the cover 12, and the tip taken out of the cooling tank 15 to the outside is a cold tea attached to the front plate 13 of the cover 12. It is connected to the opening / closing plug 16 for taking out.

A cooling water injection pipe 17 is arranged in the lower portion of the cooling tank 15, and a cooling water supply pipe 18 connected to the injection pipe 17 is connected to the injection pipe.
When cooling water as a cooling medium is supplied to the inside of the 17, the cooling water is jetted obliquely downward from a plurality of nozzles 19 formed in the jet pipe 17.

The cooling water is stored in the cooling tank 15 by the injection of the cooling water. In order to keep the cooling water level constant, the cooling tank 15
An overflow hole 20 is provided in the upper part of the.

Further, a temperature sensor 21 is provided in the cooling tank 15, and when the temperature of the cooling water exceeds the set temperature of the temperature sensor 21, the solenoid valve 22 attached to the cooling water supply pipe 18 is opened, and When the temperature falls below the set temperature, the solenoid valve 22 is closed.

Reference numeral 23 in the figure denotes a drain pipe for discharging the cooling water in the cooling tank 15.

Now, by putting tea leaves in the tea strainer 8 and supplying hot water into the hot water storage tank 1 from the hot water supply pipe 6 of the water heater 5, hot tea is stored in the hot water storage tank 1. Therefore, hot tea can be taken out from the opening / closing plug 14 by opening the opening / closing plug 14 for taking out hot tea.

The hot tea in the hot water storage tank 1 flows into the other take-out pipe 11, and the hot tea in the pipe is cooled by exchanging heat with the cooling water in the cooling tank 15. Therefore, by opening the opening / closing plug 16 for taking out cold tea, cold tea can be taken out from the opening / closing plug 16.

On the other hand, the hot tea in the take-out pipe 11 is cooled by heat exchange with the cooling water as described above.
It is preferable to increase the heat exchange rate by lengthening the pipeline of the portion connected to the inside of the cooling tank 15. In the case of the embodiment, the take-out pipe 11
Is bent in a zigzag shape. Its take-out pipe 11
If the fins are attached to the fins, the heat exchange rate can be further increased, so it is preferable to attach the fins.

[Effect of device]

As described above, in this invention, the two take-out pipes are connected to the hot water storage tank in which tea is stored, and one of the take-out pipes is cooled by contact with the cooling medium filled in the cooling tank. Two kinds of tea, hot tea and cold tea, can be provided by one device.

Further, since the water heater using propane gas as the fuel and the cooling tank to which the cooling medium is supplied are used, hot tea and cold tea can be formed in a place without electric equipment.

Further, since a large amount of hot water can be continuously formed in the water heater, a large amount of tea can be formed in a short time, and it is possible to sufficiently cope with hot tea reception in a place where a large number of people gather.

In addition, since it has a compact structure with a cooling tank arranged below the hot water storage tank, it does not require a large space for installation,
It can be easily installed in any place.
