Description

[Detailed Description of the Invention] The present invention relates to a water storage device for use in an aircraft water heater.

Since water heaters for passenger aircraft must provide hot water to passengers for a certain period of time, power must be temporarily supplied to the water heater, which is difficult. Therefore, a boiler is installed at the top to boil water, and a water storage device is installed at the bottom to store the hot water, and the hot water that is boiled in the boiler is dripped into the dripping spout of the storage device to store hot water.

However, in conventional aircraft water heaters, hot water may be discharged from the drip spout of the water storage device due to shaking during flight or impact upon landing.

FIG. 1 shows an example of a conventional water heater for an aircraft, in which a boiler, generally indicated by 1, is provided at the top, and a water storage device, generally indicated by 2, is provided below the boiler 1. Boiler 1 is equipped with electric heater 3 and boils water. Hot water boiled in the boiler 1 drips into the drip spout 5 of the water storage device 2 through a pipe 4 and is stored in the water storage device 2. A faucet 6 is attached to the water storage device 2.

For hygienic reasons, the water storage device 2 needs to be cleaned from time to time, so the boiler 1 and the water storage device 2 are separate bodies, and the water storage device 2 is removably mounted below the boiler 1.

On the other hand, since the drip spout 5 of the water storage device 2 was a funnel-shaped device that simply received the hot water dripping from the boiler 1 as shown in the figure, hot water was discharged from the drip sprue 5 due to shaking during flight or impact upon landing. However, there were cases where the water leaked out through the gap S between the boiler 1 and the water storage device 2.

The present invention was devised to eliminate the above-mentioned drawbacks of conventional aircraft water heaters.The purpose of this invention is to ensure that even when shaken during flight or by impact upon landing, water can be virtually boiled from the drip spout of the water storage device. To provide a water storage device for an aircraft water heater which does not discharge water.

Therefore, according to the present invention, in an aircraft water heater that has a boiler in the upper part that boils water and a water storage device in the lower part that stores the water boiled by the boiler separately from the boiler, hot water drips from the boiler. To provide a water storage device for an aircraft water heater, in which a small hole is opened at the tip of a drip spout of the water storage device and a cylindrical body hanging down inside the water storage device is attached.

An appropriate number of small holes may be formed at the tip of the cylindrical body, for example, one at the tip and one on each side on the peripheral wall slightly above the tip.

In this way, by attaching a cylinder with a small hole at the tip to the dripping spout of the water storage tank that hangs down into the water storage tank, it is possible to prevent the inside of the water storage tank from being damaged by shaking during flight or impact upon landing. Virtually no hot water is discharged from the drip sprue.

An embodiment of the present invention is shown in FIG. 2, in which a boiler 1 similar to that shown in FIG. 1 is placed above a water storage device 2. The water storage device 2 is made of stainless steel, for example, and includes a drip spout 5 and a faucet 6 for receiving hot water dripping from the boiler 1. A cylindrical body 7 having a small hole 8 at its tip and hanging down into the hot water storage device 2 is attached to the dripping spout 5.

In the illustrated example, there is one small hole 8 at the tip of the cylinder 7,
Slightly above it, there are openings in the surrounding wall, one each on the left and right.

In this way, the drip spout 5 of the water storage tank 2 is fitted with a cylinder 7 that has a small hole 8 at its tip and hangs down inside the water storage tank 2, so that it can be used easily during shaking during flight or during landing. Even if the hot water in the hot water storage device 2 vibrates (undulates) due to the impact, there is virtually no possibility that the hot water will be discharged from the drip sprue 5. Therefore, if a water heater equipped with such a water storage device is used as an aircraft water heater, the conventional dripping of hot water from the water storage port due to shaking during flight or impact upon landing can be virtually eliminated.
