The basic technology is to forcibly suck the air inside a sealed hollow chamber by the rotation of a rotating body and exhaust it to the outside, reducing the pressure in the room and balancing the pressure difference between the inside and outside.

This is a method of generating heat, and the air inside the sealed hollow chamber is forcibly sucked in by the rotation of a rotating body and exhausted to the outside, reducing the pressure in the room and keeping the pressure difference between the inside and outside at a nearly constant equilibrium state. While maintaining this equilibrium state, the rotating action of the rotating body is continued to promote frictional action with the air to generate frictional heat, and this frictional heat heats the inside of the hollow chamber, and further, manually or automatically operates the inside of the hollow chamber. This is a reduced-pressure equilibrium heating method in which outside air is supplied with

That is, this invention concentrates the frictional heat generated by the rotational action of the rotary body into the heat exchange section through the heat storage space provided on the exhaust side of the chamber, and makes the heat exchange section have a constricted structure so that the heat storage space is It is an object of the present invention to provide a reduced-pressure equilibrium heat generation method and an apparatus thereof, which improve the heat generation effect by more effectively compressing the heat generation air introduced into the chamber, thereby making it possible to rapidly raise the temperature inside the chamber.

In addition, this invention effectively exchanges heat between the hot air discharged outside the chamber through the heat exchanger and the outside air sucked into the chamber by the heat exchange mechanism, thereby minimizing the loss of thermal energy within the chamber.

Embodiments of the apparatus according to the present invention will be described below with reference to the drawings.

In each figure, 1 is a chamber with a closed structure with or without a door structure 2, 3 is a chamber 1
If you want to use the chamber 1 itself as a heat source, such as a pot, use a material with excellent thermal conductivity. 1
If it is desired to lead the heated air inside to the outside using a connecting pipe (not shown), it is constructed as a heat insulating structure. Reference numeral 4 denotes a decompression friction heat generation mechanism, which is composed of an electric motor 5, one or more fans 6, and a tubular tube 7 covering the fans 6, with a small gap g between the fans 6 and the tubular tube 7. A frictional heat generating section 8 is formed in the space formed by the tubular tube 7 in which the fan 6 rotates, so that the structure can improve the frictional effect with the accumulated air. In addition,
The decompression friction heat generation mechanism 4 can be freely changed such as the diameter of the fan 6, the number of blades 6a, the inclination angle of the blade 6a, the distance between the fans 6, and the number of fans 6 installed. The configuration shown in No. 55089 "Rotating body with multi-stage fan" can be adopted. Further, the fan 6 is constituted by a rotating blade 6a having a desired shape such as a propeller fan or a shirozko fan, has a desired inclination angle, and has a rotation direction determined so as to suck and exhaust air within the chamber 1. Furthermore, it has a configuration that improves the friction effect with the accumulated air. Reference numeral 9 denotes a cylindrical exhaust passage connected to the exhaust side opening 4a of the decompression frictional heat generation mechanism 4, and the opening end 9a of the passage 9 is open to the outside of the chamber 1 in the embodiment shown in FIG. However, in the embodiment shown in FIG.

Reference numeral 13 denotes a heat storage space of the exhaust passage 9, which may be formed outside of the outermost fan 6;
The distance between the exhaust passage 9 formed in the next stage and the heat exchange section 14 having a throttle structure can be set to a desired length.

Note that one or more heat exchange sections 14 can be installed, and each structure has a constricted structure with a large number of parallel small passages 15 of small diameter, and a large number of small passages 15 in a direction perpendicular to the exhaust passage 9. Parallel heat radiating fins 16 are arranged in series to form a heat exchange passage 17 parallel to the heat radiating fins 16.

18 is a heat exchange passage 1 along the heat exchange section 14.
This is a forced heat exchange fan that can effectively suck the airflow passing through the chamber 7, exchange heat, and forcibly circulate it inside the chamber 1, thereby heating and raising the air inside the chamber 1. This fan 18 can be omitted if swirling convection can be generated in the air within the chamber 1 using an attached mechanism such as that disclosed in Japanese Patent Publication No. 58-21185.

Next, the inside air exhaust section 10 and the outside air intake section 11
The heat exchange mechanism 12 composed of the following will be described.

That is, in this heat exchange mechanism 12, the outside air intake section 11 is integrated with the inside air exhaust section 10 configured as a large number of thin tubes 19 arranged in a row and a large number of heat exchange plates 20 that cross the thin tubes 19 orthogonally. Further, the outside air intake section 11 has a valve port 22 on its inlet side that is opened and closed by a valve 21.
The spaces 24, 24 provided on both sides of the inside air exhaust section 10 are partitioned into a large number of spaces 24, 24 provided on both sides of the inside air exhaust section 10 by partition walls 23 provided alternately across the thin tubes 19 from opposite directions. The innermost end 11a on the outlet side is opened toward the interior of the chamber 1. The valve 21 of the valve port 22 can be operated automatically or manually. Reference numeral 25 denotes an outside air introduction mechanism that is directly connected to the chamber 1, and consists of a conduit 26 and a valve 27. In the embodiment shown in FIG. The valves 27 can be opened and closed manually or by instructions from a controller (not shown), and a plurality of valves 27 can be installed at necessary locations in the chamber 1.

In addition, 28 is a guide weir formed in the tubular cylinder 7;
Reference numeral 9 indicates a motor shaft, and reference numeral 30 indicates an outside air cooling pipe for preventing the electric motor 5 from overheating. In addition, the tubular cylinder 7
The relationship between the motor 5 and the electric motor 5 and the fan 6 is shown as having a tubular tube 7 and an annular passage structure with the electric motor 5 and the fan 6 at the center, but the structure is not limited in any way.

The action will be explained based on the above structure.

First, let's talk about Figure 1.

When the electric motor 5 is energized and the fan 6 is rotated, the decompression frictional heat generation mechanism 4 is activated, and the air in the sealed chamber 1 is gradually drawn through the exhaust passage 9 by the suction and exhaust action of the fan 6. Exhausted,
The pressure inside the chamber 1 is reduced, and the pressure difference between the inside and outside of the chamber 1 gradually increases. Then, when a certain pressure difference is reached, a fairly constant equilibrium state is maintained.
In this equilibrium state, a phenomenon of air stagnation occurs in the frictional heat generating section 8 within the rotation area of the fan 6.
As the frictional action with the fan 6 continues to repeat, frictional heat is generated and the temperature gradually rises, and the rotating exhaust action of the fan 6 attempts to forcefully send heated air into the heat storage space 13. Therefore, a compression action is performed and compression heat is also generated, and together with the frictional heat, the air temperature within the heat storage space 13 rises rapidly. Furthermore, the heat within this heat storage space 13 propagates to the next stage heat exchange section 14, effectively heating the air passing through the heat exchange passage 17 of this section 14, and raising the air temperature within the chamber 1.

Furthermore, after the air temperature inside the chamber 1 rises, if the valve 27 of the outside air introduction mechanism 25 is opened and outside air is introduced into the chamber 1, the heated air inside the chamber 1 is discharged to the outside through the exhaust passage 9. .

Next, the case shown in FIG. 2 will be described.

By energizing the electric motor 5 and rotating the fan 6, the pressure difference between the inside and outside of the chamber 1 gradually reaches a constant equilibrium state, and the heated air is rapidly stored in the heat storage space 13 of the exhaust passage 9. However, in the heat exchange section 14, the series of operations in which the air in the chamber 1 is heat exchanged and the air in the chamber 1 is heated is exactly the same as in the case described above.

In this reduced pressure equilibrium heat generation state, the outside air intake section 11
When the valve 21 and the valve port 22 are opened, outside air flows into the chamber 1 while meandering through the spaces 24, 24 along the partition wall 23, and also flows into the chamber 1.
The air inside the chamber 1 is discharged from the exhaust passage 9 to the outside of the chamber 1 via the inside air discharge section 10.

By the way, since the inside air discharge part 10 and the outside air suction part 11 are equipped with the heat exchange mechanism 12, the inside air that still has residual heat is almost completely heat exchanged during the flow of outside air and flows into the chamber 1. Therefore, a rapid temperature drop within the chamber 1 can be prevented. When this state is continued, a reduced pressure equilibrium state is maintained, and the internal temperature gradually rises.

If you want to rapidly lower the temperature, operate the outside air introduction mechanism 25, open the valve 27, and directly feed outside air into the chamber 1 to gradually reduce or eliminate the pressure difference between the inside and outside of the chamber 1 and achieve the desired temperature. You can get the internal temperature.

The embodiments of this invention have been described above, but
Of course, a plurality of decompression friction heat generation mechanisms 4 can be installed depending on the volume of the chamber 1.

According to this invention, the heat storage space and the heat exchange part are provided on the exhaust side to prevent heat from escaping and to store and store heat.
Since heat exchange is performed effectively, thermal efficiency is high and the air temperature within the chamber can be raised extremely effectively.

In addition, the chamber can not only store objects to be processed for drying or heating purposes, but also
Its uses are wide-ranging, such as by connecting piping and the like to extract the thermal energy inside the chamber to the outside and use it for purposes such as heating and space heating.
