Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in a hot water tank used, for example, in a beverage vending machine to supply hot water for drinking, in particular to facilitate maintenance and inspection.

For example, a vending machine that sells drinks such as hot coffee is equipped with a hot water tank inside the machine, and the hot water tank heats the supplied tap water, and the hot water is supplied from the hot water outlet for drinking.

In the hot water tank, in order to shorten the boiling time of the water and to prevent the temperature of the water from decreasing even when drinks are sold continuously, a partition plate is provided horizontally that divides the inside of the tank body into upper and lower halves, leaving only a part of the tank body. It is being

A tap water inlet is provided in the lower chamber, a hot water outlet is provided in the upper chamber, and the water in both chambers is heated by heaters.

At this time, the heater in the upper chamber heats the water flowing in from the lower chamber in a short time due to the blocking effect of the partition plate, and hot water is continuously supplied from the hot water outlet.

Hot water tanks that supply hot water for drinking purposes are required to be clean at all times for hygienic reasons, and the interior is inspected and cleaned on a regular basis, and the partition plate must be removed at this time. .

However, in the past, the partition plate was screwed to the side wall of the tank body, making it troublesome to remove.

The purpose of this invention is to eliminate the above-mentioned drawbacks and to provide a hot water tank for a beverage vending machine that is equipped with a partition plate that can be easily attached and detached for inspection and cleaning.

The purpose of this invention is to provide a hot water tank for a beverage vending machine that is equipped with a horizontal partition plate that partitions the inside of the tank into upper and lower parts, and that separates the water supplied to the lower chamber from the hot water outlet of the upper chamber. A pipe for inserting a thermometer from the outside into the upper chamber is installed horizontally, and the partition plate is removably attached to this pipe via a hanging fitting.

Hereinafter, embodiments of this invention will be described based on the drawings.

In FIG. 1, 1 is a hot water tank used in a beverage vending machine, and 2 and 3 hot water tanks 1 each have a tank body and a lid, which are made of stainless steel plates.

A water supply pipe 4 is connected to a water pipe and is equipped with a solenoid valve 5. The solenoid valve 5 is electrically connected to a water storage amount detection device 8 equipped with a float 7.

Reference numeral 9 denotes a drinking hot water supply pipe equipped with a solenoid valve 10, and the solenoid valve 10 is opened based on a beverage sales command.

Furthermore, in the tank body 2, there is a space of 80% of the cross-sectional area of the tank body.
Partition plate 1 made of stainless steel plate having a flat area of 90% to 90%
2 into an upper chamber 13 and a lower chamber 14.

The water supply port 4a of the water supply pipe 4 opens into the lower chamber 14, and the hot water outlet 9a of the waist supply pipe 9 opens into the upper chamber 13.

Furthermore, heaters 16 and 17 are provided in the upper chamber 13 and the lower chamber 14, respectively, and these heaters are energized and controlled by thermostats 18 and 19, respectively, so that the water in each chamber reaches a required temperature.

A pipe 22 is provided in the upper chamber 13 into which a thermometer 21 is inserted to measure the temperature of hot water in the room.

This pipe 22 is a stainless steel pipe with a sealed tip, and is welded to the side wall of the tank body 2 so as to be positioned horizontally within the tank body 12.

After the temperature sensing part of the thermometer 21 is inserted, the insertion opening is closed so that the temperature sensing part can reliably sense the temperature of the hot water.

Further, the above-mentioned partition plate 12 is held on this horizontally provided pipe 22 as follows.

That is, on the upper surface of the partition plate 13, as shown in FIG.
is installed.

The tip 31a of this hanging fitting 31 is attached to the pipe 2 by spring force.
It is formed into a circular hook shape with an inner diameter slightly smaller than the outer diameter of the pipe 22 and an opening so that the lower part can be pushed into the pipe 22 so as to be fixed to the pipe 22.

In the hot water tank 1 described above, the cold water supplied through the water supply pipe 4 is first supplied to the lower chamber 1 by the operation of the water storage amount detection device 8.
4, where it is heated by a heater 17,
As the water level rises, it flows into the upper chamber 13.

Cold water does not directly flow into the upper chamber 13, and due to the blocking effect of the partition plate 12, the hot water in the upper chamber 13 is efficiently heated by the heater 16.

From the hot water outlet 9a opening into the upper chamber 13, hot water heated to a required temperature is supplied in a short time.

When inspecting and cleaning the hot water tank 1, by grasping and lifting the hanging fitting 31, the partition plate 12 can be easily removed from the pipe 22 and taken out to the outside.

Thereby, there is no obstruction between the upper chamber 13 and the lower chamber 14, making inspection and cleaning extremely easy.

Attaching the partition plate 12 after inspection and cleaning is as simple as pushing the tip 31a of the hanging fitting 31 into the pipe 22, and the partition plate 12 is reliably held by the spring force of the hanging fitting 31.

As mentioned above, according to this invention, a horizontal partition plate is used to divide the inside of the tank into upper and lower parts so as to separate the water supplied to the lower chamber from the hot water outlet of the upper chamber, and a thermometer is inserted into the upper chamber from the outside. The pipe for the tank is installed horizontally, and the pipe is detachably attached to the pipe via a hanging bracket, so when inspecting and cleaning the inside of the tank, the partition plate can be easily attached and detached, making inspection and cleaning easier. It can be done in a short time.
