Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention utilizes a disposable body warmer to warm compressed air with the disposable body warmer to generate warm air, and to supply the warm air to a diver or other person with a cold body underwater. It relates to a source device.

[0002]

2. Description of the Related Art It is well known that dry suits for diving are widely used not only in cold regions for work but also for general leisure divers from autumn to spring. Compared to those for leisure, thicker inner suits for heat insulation have fittings and sizes that are difficult to wear, and heat insulation is often insufficient when the water temperature is low or when diving for a long time. Therefore,
When it is predicted that insufficient heat retention during diving is expected, a heat source such as a disposable body warmer is often used in advance inside the dry suit.

In addition, mountain accidents such as being distressed during mountain climbing or being left behind in Nakashu due to an accident such as a dam breach during a camp in Nakasu of Tanigawa, etc. When a person is rescued, there is often no way to warm the chilled body of the rescued person, but only to warm the body with a blanket or the like.

[0004]

However, when a disposable warmer is used inside a dry suit before diving, the air does not generate heat unless the disposable warmer is properly contacted with air. Moreover, the disposable body warmer
Only a part of the compressed air flowing into the inside of the dry suit (the compressed air around the disposable body warmer) can be heated, and it is difficult to warm the entire compressed air.

If the paper bag of a disposable body warmer is torn by a large movement of a diver, the fine powdered heat-generating composition (for example, iron oxide, etc.) is scattered to the outside and generates heat. The amount decreases. In addition, it is easily broken by water intrusion, and reacts with seawater to generate abnormal heat. In addition, since the heat-generating composition such as the above-mentioned iron oxide that has abnormally generated heat during diving cannot be taken out, there is a concern that the burn may occur.

[0006] On the other hand, even when rescued by a rescue squad or the like, the body cannot be sufficiently warmed only with a blanket or the like. Also, if the rescue team prepares a heat source such as a disposable body warmer, although it is more effective than warming the body only with a blanket etc., there is a problem that if the air does not touch the disposable body warmer well, it will not generate heat, There are problems that only the area around the disposable body warmer can be heated, and that if the paper bag of the disposable body warms, the calorific value decreases.

The present invention has been made in view of such circumstances, and warms the entire compressed air supplied to the inside of a dry suit, the inside of a blanket or the like (the space between a blanket or the like and the body) or the like by a disposable warmer. It is another object of the present invention to provide a heat source device that can be used and does not damage a paper bag or the like of a disposable body warmer.

[0008]

In order to achieve the above object, a heat source apparatus according to the present invention provides a sealed container with a compressed air introduction hole for introducing compressed air into the inside, and discharging the compressed air inside. With a compressed air discharge hole, the closed container has a structure that can accommodate a disposable warmer in and out freely,
In the closed container, weakening means for weakening the force of the compressed air introduced from the compressed air introduction hole is provided, and the force of the compressed air introduced from the compressed air introduction hole is weakened by the weakening means to make contact with the disposable body warmer. The configuration is adopted.

That is, the heat source device of the present invention has a structure in which a closed container is provided with a compressed air introduction hole and a compressed air discharge hole, so that the closed container can accommodate a disposable body warmer therein. Therefore, in the present invention, by introducing compressed air into the sealed container from the compressed air introduction hole with the disposable warmer housed in the closed container, the introduced compressed air is brought into contact with the disposable warmer to generate heat. Then, after the whole of the compressed air passing through the closed container is warmed by the generated heat, the compressed air can be discharged from the compressed air discharge hole and supplied to the inside of the dry suit, the blanket or the like. Moreover, a weakening means is provided in the closed container,
Since the force of the compressed air introduced from the compressed air introduction hole is weakened by this weakening means, the paper bag or the like of the disposable body warmer is broken by the compressed air introduced from the compressed air introduction hole, and the fine powder inside the disposable body warms up. The heat-generating composition in the form of a scatter is not scattered outside, and does not flow into the inside of a dry suit, a blanket or the like. Therefore, a predetermined heat generation amount can be secured over a long period of time. Furthermore, even if the inside of the dry suit is flooded, there is no risk of burns.

In the present invention, the weakening means comprises a pipe having an opening at one end connected to the compressed air introduction hole, and an opening at the other end of the pipe near the inner peripheral surface of the closed container, and is provided at the inner peripheral surface. When facing, when the compressed air introduced from the compressed air introduction hole is passed through the pipe and then flows into the closed container, the compressed air flowing out of the pipe collides against the inner peripheral surface of the closed container, The momentum can be reduced.

[0011] In the present invention, the weakening means may include:
In the case of a baffle plate which is disposed at a predetermined interval between the compressed air introduction hole and the compressed air introduction hole, when the compressed air introduced from the compressed air introduction hole flows into the closed container, the compressed air is applied to the baffle plate. Collisions can reduce that momentum.

[0012]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 3 show an embodiment of the heat source device of the present invention. In these figures, reference numeral 1 denotes a closed container, which is provided with a cylindrical base body 2 having a bottom and an open cylindrical base lid section 3 for sealing an upper end opening of the base body 2 in an airtight manner. The base body 2 and the base lid 3 are made of a metal such as a contact-resistant aluminum alloy or a plastic such as an ABS resin, and have a thickness sufficient to withstand a medium pressure (about 10 atm) of compressed water for diving. I have.

As shown in FIG. 4, such a closed container 1 is used for adjusting buoyancy and preventing squeeze inside the dry suit 20 during diving when the user dive with the dry suit 20 in a place where the water temperature is low. Medium pressure hose 2 communicating with a compressed air supply source (not shown) such as a compressed air cylinder via a primary pressure reducing valve (not shown)
1 is detachably attached to a connection portion between an intake valve 22 provided on the dry suit 20. The intake valve 22 is a push-button open / close valve, and is normally in a closed state. The push-button 2 is urged toward the valve-closing side by a spring (not shown).
The valve is opened by pressing 2a.
In FIG. 4, 23 is an exhaust valve. This exhaust valve 23
Also, this is constituted by a push button type open / close valve, which is normally in a valve closed state, and has a structure in which the valve is opened by pressing a push button 23a urged toward the valve closing side by a spring (not shown). I have. Reference numeral 24 denotes a diver.

As shown in FIG. 3, the base body 2 comprises a cylindrical body 4 and a disk-shaped bottom plate 5 having an annular flange 6 protruding from the outer peripheral surface of the lower end. A screw portion 4a formed on the inner peripheral surface of the lower end portion of the body portion 4 and a screw portion 5a formed on the outer peripheral surface of the bottom plate portion 5 are screwed in an airtight manner (in this embodiment, the body portion 4 is formed). And the bottom plate portion 5 cannot be removed). The body 4 has a threaded portion 4b formed on an outer peripheral surface of an upper end thereof.
Is removably screwed into a threaded portion 7a formed on the inner peripheral surface of the peripheral side wall 7 of FIG.

An annular O-ring locking groove 9 is formed in the upper end surface of the body portion 4, and a waterproof and pressure-resistant O-ring 10 is fitted into the groove 9. I have. An annular O-ring locking groove 11 is formed in the lower part of the screw portion 4b on the outer peripheral surface of the upper end portion of the body portion 4. An O-ring for waterproof and pressure resistance is formed in the groove 11. 12 are fitted. The O-rings 10 and 12 keep the compressed air sealed inside the base body 2 with the base body cover 3 covered by the base body 2 and prevent water from entering from the outside.

Screw holes 13 and 14 are formed in two places in the ceiling plate portion 8 of the base cover 3 in a penetrating manner, and one (right side in the drawing) screw hole 13 (compressed air introduction hole). The female connector 15 is screwed into the female connector 15, and the female connector 16 is screwed into the other (left side in the drawing) screw hole 14 (compressed air discharge hole). The male connector section 15 has the same structure as the male connector section 26 attached to the intake valve 22, and the female connector section 16 has the same configuration as the female connector section 25 attached to the tip of the medium-pressure hose 21. The structure is as follows. Then, both connecting connector male parts 15, 26 and both connecting connector female parts 16,
25 are configured such that they can be detachably connected with one touch.

For this purpose, the female connector portion 25 is connected to the male connector portion 15 and the female connector portion 16 is connected.
When the male connector 26 is connected to the airtight container 1, the compressed air supplied from the compressed air supply source passes through the medium pressure hose 21, the female connector 25, the male connector 15, and a pipe 17 described later. And flows out toward the intake valve 22 through the female connector portion 16 and the male connector portion 26. When these connections are released and the female connector portion 25 is directly connected to the male connector portion 26, the compressed air supplied from the compressed air supply source can be directly supplied to the intake valve 22 side. Further, since the two male connectors 15 and 26 and the female female connectors 16 and 25 have a structure in which the valve is closed in the non-connected state, the compressed air in the sealed container 1 is maintained even when the connection is released. Does not leak out.

At the lower end of the male connector 15 screwed into the right screw hole 13 of the base lid 3,
An upper end of a pipe 17 hanging down toward the upper surface of the bottom plate 5 of the base body 2 is fixed. The lower end opening of the pipe 17 extends to near the upper surface of the bottom plate 5, and faces the upper surface of the bottom plate 5. This allows
When the compressed air supplied from the compressed air supply source passes through the pipe 17 and flows out of the lower end opening, the bottom plate 5
Collides with the upper surface of the ship, and its momentum weakens.

In the above configuration, for example, warm air can be supplied to the inside of the dry suit 20 as follows. That is, first, the base cover 3 is opened, and the disposable body warmer 27 is wound in the base body 2 (FIG. 3).
) This disposable body warmer 27
Is composed of a finely powdered heat-generating composition (not shown) contained in an air-permeable paper bag (not shown). Next, the base cover 3 is closed to the base body 2, the female connector 25 is connected to the male connector 15, and the male connector 26 is connected to the female connector 16.
Concatenate. After that, dive. Then, when compressed air (warm air) is required during this dive, the push button 22a of the intake valve 22 is pressed.

As a result, the compressed air supplied from the compressed air supply source is supplied to the medium pressure hose 21 and the female connector 2.
5, through the male connector 15 and the pipe 17, flow out of the lower end opening of the pipe 17 and flow into the closed container 1. At this time, the compressed air flowing out from the lower end opening of the pipe 17 collides with the upper surface of the bottom plate portion 5 and its momentum is weakened. After the inflow, the compressed air comes into contact with the disposable body warmer 27, and the contact causes the heat-generating composition of the disposable body warmer 27 to generate heat, and the generated heat heats the compressed air.
After that, the warm air is exhausted from the female connector section 16 and passes through the intake valve 22 in the open state, so that the dry suit 20
Supplied internally. At this time, in the closed container 1, the compressed air is discharged from the female connector 16 of the base cover 3 after colliding with the upper surface of the bottom plate 5. It comes into contact with the entire surface for a long time, or passes around the vicinity.

If for some reason, disposable body warmer 2
7 is abnormally heated, the male connector 15
The connection between the female connector portion 25 and the female connector portion 16 and the male connector portion 26 are released with a single touch. Then, the connection connector female portion 25 and the connection connector male portion 26 are connected with one touch. The closed container 1 can be safely removed by such a simple operation in water. Further, the compressed air supplied from the compressed air supply source can be directly supplied to the inside of the dry suit 20.

As described above, in this embodiment, after the compressed air supplied from the compressed air supply source is heated by the disposable warmer 27 outside the dry suit 20 to warm it up,
It can be supplied inside the dry suit 20. Moreover, since the compressed air flowing into the closed container 1 is weakened by the collision with the upper surface of the bottom plate 5, when the compressed air comes into contact with the disposable body warmer 27, the compressed air breaks the paper bag and forms fine powder inside. The exothermic composition is not scattered outside. Furthermore, the compressed air in the closed container 1 makes long contact with the entire surface of the disposable body warmer 27 or passes around the vicinity thereof, so that the compressed air is efficiently warmed, and the compressed air having a higher temperature is dried inside the dry suit 20. Supplied to
