Description

[Detailed Description of the Invention] This invention is a novel hot air system that can be used in a wide range of industrial fields, from indoor heating, agricultural applications such as greenhouse heating, to various applications that provide a constant temperature atmosphere. METHODS AND APPARATUS THEREOF.

The inventor of this invention is Japanese Patent Application Publication No. 57-19582, Japanese Patent Application Publication No. 57-1958
No. 19583, JP-A-57-55378 and JP-A-57-
A series of subsequent inventions, such as No. 55379, proposed a reduced pressure equilibrium heating method and a drying method or apparatus using the method.

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 equilibrium state is maintained and this equilibrium state is maintained while 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 interior of the hollow chamber. This is a heating method that uses the rotating action of a rotating body to forcibly suck the air inside a sealed hollow chamber and exhaust it to the outside, reducing the pressure in the room and keeping the pressure difference between the inside and outside in a well-balanced state. At the same time, while maintaining this equilibrium state, the rotating action of the rotating body is continued to promote the frictional action with the air and generate frictional heat, and this frictional heat heats the inside of the hollow chamber. This is a reduced pressure equilibrium heating method in which outside air is supplied by operation.

Furthermore, in contrast to the above-mentioned reduced pressure equilibrium heating method and apparatus, we developed and proposed a pressurized equilibrium heating method in Japanese Patent Application Laid-Open No. 127779/1983.

In either case of depressurization or pressurization, the frictional heat obtained mainly by the frictional action with air in a constant pressure equilibrium state of depressurization or pressurization caused by the rotational action of a rotating body is used as clean thermal energy. It is characterized by:

The present invention is based on the basic concept of the invention of this type of prior application, and further develops this basic concept to provide a novel hot air method and apparatus for obtaining clean thermal energy as hot air.

That is, the present invention is a hot air method in which gas is sucked in and discharged by the rotation action of a rotating body, and in which two or more rotating bodies each having a rotating shaft perpendicular to the front and rear partition plates of a hollow body are connected to each other. Adjacent units are arranged in opposite directions, and the intake gas is limited by limiting the amount of gas taken in by the gas inlet and/or the amount of gas discharged from the gas outlet to less than the gas suction and discharge capacity of the rotating body. The present invention provides a hot air method and an apparatus for generating hot air by generating heat through the rotational action of a rotating body within a rotating region while maintaining a desired constant pressure equilibrium state.

An embodiment of the apparatus according to the present invention will be described below with reference to the drawings. In addition, the embodiment shown here shows a case where it is used for room heating under reduced pressure equilibrium.

In each figure, 1 indicates a wall that separates room A and room B, and a hollow body 2 is embedded in wall 1 so that both rooms A and B can be heated separately or at the same time. ing. 3 and 4 are gas inlets that open to both chambers A and B and face the top of the hollow body 2; 5 and 6 are gas exhaust ports that also open to both chambers A and B and face the bottom of the hollow body 2. shows. 7 indicates a rotating body, and in the illustration, three electric motors 7a, 7b, 7c
have their rotating shafts 8 perpendicular to the front and rear airtight and pressure-resistant partition plates 9, 10 that constitute the outer shell of the hollow body 2, and the successively adjacent electric motors 7a, 7b, 7c are different from each other. It is arranged in the direction. 11 indicates a rotating blade of the rotating body 7;
It can have a desired structure such as a propeller fan or a sirotsko fan, has a desired inclination angle, and inhales gas from the gas inlets 3 and 4 in the hollow body 2, and discharges the gas from the gas exhaust ports 5 and 6. The direction of rotation is determined so that 12 is a gas introduction part provided on the gas inflow side of each rotating body 7;
Reference numeral 13 indicates an opening formed with a small gap g between the rotary blade 11 and the partition plates 9 and 1 of the hollow body 2.
A rotation area R of the rotary body 7 is formed along the opening 13, and a rotation area R of the rotation body 7 is formed in the rotation area R of the rotation area R. In the suction gas, frictional heat is effectively generated by the repeated repetition of the frictional action of the rotating blades 11, and the temperature of the gas can be increased. Reference numeral 16 indicates a gas suction section formed on the output side of each rotating body 7, and the suction section 16 of the first and second stage electric motors 7a, 7b is integrated with the gas introduction section 12 communicating with the next stage. The suction section 16 of the third and final stage electric motor 7c is connected to the gas discharge ports 5 and 6 to form a kind of pressurization section _L1 and _L2 . It forms H.

Furthermore, the gas introduction section 12 connected to the gas inlets 3 and 4 forms a kind of pressure reduction section _L0 .
Reference numerals 17 and 18 indicate a gas suction chamber in which the gas inlets 3 and 4 are formed and a gas discharge chamber in which the gas discharge ports 5 and 6 are formed. Communication operations to A and B can be performed separately or simultaneously. 20 is a switch mechanism for operating the rotating body 7 provided on the wall 1, and 21 is a cooling pipe for cooling the electromagnetic drive section of the rotating body 7.

Incidentally, the opening area of the gas suction ports 3 and 4 is configured to be narrowed down to a size that can limit the gas suction amount and gas discharge amount to less than the gas suction and discharge capacity of the installed rotating body 7. The gas introduction part 12 is formed on the gas inflow side of the rotating body 7 in sequence.
A desired balanced reduced pressure state is formed in the structure, and with this configuration, a gas stagnation action occurs in the stagnation portion 15 formed in the rotation region R of the rotating body 7. As a result, the frictional action by the rotating blades 11 is promoted.

Furthermore, by adjusting the opening area of the gas inlets 3 and 4, the blowout amount and temperature of the hot air can be freely adjusted.

Although not shown, a desired heat storage material may be incorporated into the hollow body 2 to store temperature.
Alternatively, a filter or the like may be detachably incorporated to remove dust in the introduced gas.

The action will be explained based on the above structure.

First, select rooms A and B to be heated, then operate the operating switch mechanism 20 to turn on the rotating body 7.
Rotate.

As the rotating body 7 rotates, air is sucked in from the gas inlets 3 and 4 that are open to either or both of the rooms A and B, and hot air is discharged from the gas exhaust ports 5 and 6 to either or both of the rooms A and B. Ru.

By the way, the amount of air sucked in from the gas intake ports 3 and 4 due to the rotational action of the first stage electric motor 7a is compared to the suction and discharge capacity of the electric motor 7a.
Since the gas pressure is limited to less than that, the gas pressure is higher in the pressure reducing part _L1 formed by the suction part 16 and the gas introduction part 12 on the output side of the electric motor 7a than in the gas introduction part 12 of the electric motor 7a. However, since the next stage electric motor 7b and the third stage electric motor 7c are rotating, the pressure reducing part L formed by the suction part 16 of the electric motor 7b and the gas introduction part 12 ₁ and _L2 are in a reduced pressure state, therefore, the pressure reduction part _L0 of the first stage gas introduction part 12 has the highest degree of pressure reduction, and the electric motors 7a and 7 of the successive and subsequent stages have the highest degree of pressure reduction.
The degree of pressure reduction in the gas pressure in the pressure reduction parts L ₁ and L ₂ gradually decreases toward b and 7c, creating a so-called stepwise pressure reduction state. It's about maintaining balance.

Incidentally, the degree of stepwise reduction in gas pressure is not necessarily constant depending on the gas suction and discharge capacity of each rotating body 7, but generally speaking, the larger the capacity is, the greater the reduction in gas pressure is.

Therefore, the gas sucked into the hollow body 2 is
There is a strong tendency for gas to stagnate in the stagnation part 15 within the rotation region R of each electric motor 7a, 7b, 7c, and therefore gas is The temperature is raised. And each electric motor 7a, 7b, 7c
The frictional heat generated in the rotation area is sequentially transferred from the first stage electric motor 7a to the second and third stage electric motors 7a.
The temperature rises as the air moves toward air 7c, and the warm air that has risen to the highest temperature can be discharged from the electric motor 7c at the final stage to the rooms A and B via the gas discharge ports 5 and 6.

Furthermore, if the three electric motors 7a, 7b, and 7c have the same gas suction and discharge capacity, each electric motor 7a,
The pressure fluctuations from the pressure reducing part 16 formed on the output side of the motors 7b and 7c to the gas introduction part 12 are such that the degree of pressure reduction decreases to 1, 1/2, and 1 as it goes toward the electric motors 7a, 7b, and 7c. It is known that the value changes to /3.

By the way, the suction section 1 of the final stage electric motor 7c
6 is in communication with the gas discharge ports 5 and 6 of the hollow body 2, so that the intake gas is forcibly discharged to the outside, thereby exerting a kind of pressurizing effect, and thus generating compression heat. As a result, hot air with increased temperature can be obtained more effectively.

By the way, since the air in the rooms A and B is repeatedly heated by the continuous operation of the rotating body 7 in the hollow body 2, the air temperature in the rooms A and B can gradually rise.

What is more, if a thermostat is connected to the rotary body 7 of the hollow body 2 to control the temperature in rooms A and B, and the temperature can be controlled intermittently, the temperature in rooms A and B can be controlled.
Constant temperature control can be easily performed.

Furthermore, since the adjacent electric motors 7a, 7b, and 7c have their rotating directions opposite to each other and the gas flow direction within the hollow body 2 is controlled in a zigzag manner, the heat generation effect is high and extremely efficient operation is achieved. can be set.

By the way, in the above-mentioned embodiment, the gas inlet side, that is, the gas suction ports 3 and 4 are throttled under reduced pressure equilibrium.
Although we have described the case in which the inside of the hollow body 2 is maintained at a constant pressure state by freely changing the amount of gas inflow, it is possible to conversely restrict the gas outlet side, that is, the gas discharge ports 5 and 6.
Warm air can be obtained by driving the rotating body 7 in the same manner as described above.

However, in this case, as the electric motor 7a of the first stage inside the hollow body 2 advances to the second stage and the third stage, the suction portion 16 of each electric motor 7a, 7b, 7c
The space constituted by the gas introducing section 12 constitutes a kind of pressurizing section, and the degree of pressurization increases step by step, and the pressurized state is determined by the gas flow state, that is, the dynamic This results in a constant pressure equilibrium.

Therefore, under the constant pressure equilibrium of such pressurization, the generation of frictional heat is promoted, and the first stage and second stage are
The amount of heat generated increases as the electric motor moves to the third stage, the third stage, and the latter stage, and eventually hot air can be discharged from the gas discharge ports 5 and 6.

In both cases of depressurization and pressurization, when starting, the gas inlets 3, 4 and the gas outlets 5, 6 are kept fully closed to achieve so-called static constant pressure equilibrium with no fluid flow. It is also possible to temporarily enhance the heating effect.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and may be implemented as the following configuration, although not shown.

(a) Hollow bodies can be buried not only in walls but also in floors and ceilings.

(b) Hollow bodies can be used by being installed stationary on various surfaces rather than being built-in.

(c) The hollow body can be configured freely, such as a screen type that can stand up, or a movable type with a pulley.

(d) The plurality of rotating bodies may be configured as a hollow body in a planar manner without being continuous in a straight line, or may be configured in a three-dimensional manner as a bent structure.

(e) At least one gas inlet and gas outlet can be formed at any desired location in the hollow body.

(f) Multiple rotating bodies can be used with the same or different abilities.

As described above, this invention is capable of effectively extracting clean hot air constantly by the constant pressure equilibrium rotation action of depressurizing or pressurizing the rotating body and frictional heat generation action, and has a simple structure. It can be provided at a low cost and has the effect of being applicable to a wide range of industries and agriculture, such as constant temperature control in indoor heating facilities and hot air control for greenhouse cultivation.
