Abstract

PURPOSE:To provide an air heater device that is efficient and consumes less electricity by an arrangement in which the hot air is made through a series of chambers with the capacity of rotating bodies sequentially becoming smaller from the air intake side. CONSTITUTION:The area of gas inlets 3, 4 of an air heater is formed in such a manner than the rate of the gas induction and delivery may be limited to be less than the capacity of the gas induction and delivery of a rotating body 7. Because of this, a desirably balanced decompression state is formed in a gas induction section 12, and so, the stagnation effect of gas develops in the rotational range R of the rotating body 7 to enhance the friction action by a rotary vane 11. As the air is gradually heated, it is delivered from outlets 5, 6. Among electric motors 7a, 7b, 7c, the motor 7a closest to the air induction side has the largest capacity and the motors 7b, 7c have the increasingly smaller capacity, while the gas induction capacity of the rotating body 7 becomes sequentially smaller. By this constitution, the hot air producing capacity of the overall device is not different from that which employs rotating bodies of the same capacity.

Description

[Detailed Description of the Invention] This invention is a novel heating system that can be used in a wide range of industrial fields, from indoor heating, agricultural applications such as heating for greenhouse cultivation, to various applications for obtaining constant-temperature surrounding air. Concerning wind equipment.

The inventor of this invention is Japanese Patent Publication No. 57-19! '582, JP-A-57
In a series of subsequent inventions such as No. 19583, JP-A-57-55378 and JP-A-57-55379, a reduced pressure equilibrium heating method and a drying method or apparatus using the method were proposed.

The basic technology is that the air inside a sealed hollow chamber is forcibly sucked in by the rotation of a single rotating body and exhausted to the outside, reducing the pressure inside the room and bringing the pressure difference between the inside and outside into a constant state of equilibrium. While maintaining this equilibrium state, the rotating action of the rotating body is continued to promote the frictional action with the air. A heating method, and further,
Air inside a sealed hollow chamber.

The rotating action of the rotating body forcefully suctions the air and exhausts it outside.
The pressure inside the room is reduced to keep the pressure difference between the inside and outside in a constant equilibrium state, and while this equilibrium state is maintained, the rotating action of the rotating body is continued to promote frictional action with the air and generate frictional heat. Let it happen.

This is a reduced pressure equilibrium heating method in which the inside of the hollow chamber is heated by this frictional heat, and outside air is fed into the hollow chamber manually or automatically.

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

Furthermore, in the patent application dated July 13, 1982 entitled "Hot Air Method and Apparatus", there is a "hot air method in which gas is sucked in and discharged by the rotational action of a rotating body", and the gas suction and discharge capacity of the rotary body is The amount of gas sucked into the gas intake port and/or the amount of gas discharged from the gas outlet port is limited to less than that, and the intake gas is kept under a desired constant pressure equilibrium state within the rotation region of the rotating body. A hot air method that generates heat through rotational action and obtains this as hot air. ” and [inside a hollow body of an airtight structure having a gas inlet and a gas outlet, the amount of gas inhaled by the gas inlet and/or the gas outlet part of the gas outlet, which rotates with a larger gas inlet and outlet capacity. A hot air device in which a rotating body is provided with a heat generating function and a constant pressure balancing function. ” and “A plurality of rotating bodies that rotate with a gas suction and discharge capacity larger than the gas suction amount of the gas suction port and/or the gas discharge amount of the gas discharge port in a hollow body of an airtight structure having a gas suction port and a gas discharge port. We proposed a hot air device in which the rotors are arranged in series and each rotating body has a heat generation function and a constant pressure balancing function.

Both depressurization and pressurization are characterized in that the frictional heat obtained mainly by the frictional action with air in a constant pressure equilibrium state of depressurization or pressurization produced by the rotational action of a rotating body is used as clean thermal energy. thing't
6ru. However, when the inventor creates warm air using multiple hollow chambers each having a rotating body in succession, even if the capacity of the other rotating bodies is lower than the capacity of the rotating body closest to the intake side, the hot air as a whole of the apparatus is It was found that there is no difference in production ability compared to using a rotating body of the same ability. In addition, when three or more such hollow chambers are connected in succession, even if the capacity of the rotating bodies is lowered sequentially from the intake side, the hot air generation capacity of the entire device will be different compared to when the capacity of all the rotating bodies is the same. I found out that there is no.

Based on these findings, it is an object of the present invention to provide an efficient hot air device with lower power consumption.

An embodiment of the apparatus according to the present invention will be described below with reference to the drawings. In addition, the examples shown in and \ show the case where it is used for indoor 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. 3.4 indicates a gas inlet opening to both chambers A and B and facing the upper part of the hollow body 2, and 5.6 indicates a gas exhaust port opening to both chambers AsB and facing the lower part of the hollow body 2. . Reference numeral 7 indicates a rotating body, and 1 (f) shows three electric motors 7a, 7b, and 7c, each of which has its rotating shaft 8 relative to the front and rear airtight and pressure-resistant partition plates 9, 10 that constitute the outer shell of the hollow body 2. Electric motors 7a, 7b, 7 located vertically and sequentially adjacent to each other
c are arranged in mutually different directions. electric motor 7a
- Among 7b and 7c, the electric motor 7a on the most intake side has the highest output, and the rotating body on the most suction side has the best rotational ability, and the ability gradually decreases as the electric motor 7b and 7c become electric motors 7b and 7c. c = A4: 2: 1
There is a fu.

3 to 11 indicate the rotating blades of the rotating body 70, which can have a desired structure such as a propeller fan or a sirocco fan, and have a desired inclination angle.

The direction of rotation is determined so that gas is sucked into the hollow body 2 through the gas inlets 3 and 4 and the gas is exhausted through the gas exhaust ports 5 and 6. Reference numeral 12 indicates a gas introduction portion provided on the gas inflow side of each rotary body 7, 13 indicates an opening formed with a minute gap g between the rotary blades 11, and the hollow body 2.
The rotation region R of the rotating body 7 is formed along the opening 13, and the rotation region R of the rotation region Part 15
The suction gas accumulated in the rotary blade 11 effectively generates frictional heat due to the continuous anti-nucleation of the frictional action of the rotary vanes 11, thereby increasing the temperature of the gas. Reference numeral 16 indicates a gas suction section formed on the output side of each rotating body 7.

The suction parts 16 of the first and second stage electric motors 7a and 7b are integrally combined with the gas introduction part 12 communicating with the next stage to form a kind of pressure reducing part 1, L, and the final 3rd tier
The suction part 16 of the stage electric motor 7c communicates with the gas outlet 5.6 to form a kind of pressurizing part H. Furthermore, the gas introduction part 12 connected to the gas inlets 3 and 4 is a kind of pressurizing part H. 017 and 1B, which form the pressure reducing part Lθ, indicate the gas suction chamber where the gas inlet 3.4 is formed and the gas discharge chamber where the gas exhaust port 5.6 is formed, and these can be switched manually or automatically. Dan)'-19 can be tilted and operated to connect rooms A and B separately or at the same time! It is now possible to 20 is a switch mechanism for operating the rotating body 7 provided on the wall 1, and 21 is a cooling pipe "r!" for cooling the electromagnetic drive section of the rotating body 7.

By the way, the opening area of the gas suction port 3.4 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. Thus, a desired balanced reduced pressure state is formed in the gas introduction part 12 which is successively formed on the gas inflow side of the rotating body 7. By configuring this way, a desired balanced pressure reduction state is created in the rotational region R of the rotating body 7. A gas stagnation action occurs in the formed stagnation portion 15, and the frictional action of the rotating blade 11 is promoted.

The opening area of the gas inlets 3 and 4 is as follows.

By adjusting the size of the hot air, the amount and temperature of hot air can be adjusted freely.

Although not shown, a desired heat storage material may be incorporated into the hollow body 2 to store the temperature, or a filter or the like may be detachably incorporated to remove dust from the introduced gas. 1 is over.

The operation will be explained based on the diagonal configuration.

First, select rooms A and B that you want to heat.

Next, the operating switch mechanism 20 is operated to rotate the rotating body 7.

As the rotating body rotates 70 times, air is sucked in through the gas inlet 3.4 opened to either or both of rooms A and H, and hot air is discharged from the gas outlet 5.6 to either or both of rooms A and B. be done.

However, the amount of air sucked in from the gas intake ports 3 and 4 by the rotational action of the first stage electric motor 7a is limited to less than the suction and discharge capacity of the electric motor 7a. Compared to the gas introduction section 12 of the electric motor 7a, the gas pressure tends to increase in the pressure reducing section formed by the suction section 16 on the output side of the electric motor 7a and the gas introduction section 12, but the continuous Since the next stage electric motor 7b and the third stage electric motor 7c are rotating, the electric motor 7
The decompression parts L formed by the suction part 16 and the gas introduction part 12 in b exhibit a reduced pressure state, and therefore the depressurization part LO of the first stage gas introduction part 12 has the highest degree of depressurization and is sequentially As the electric motors 7a, 7b, and 7c are moved toward the later stages, the degree of gas pressure reduction in the pressure reduction section L gradually decreases, creating a so-called stepwise pressure reduction state, and each pressure reduction state corresponds to the gas flow state, that is, the gas flow state. If we maintain a dynamic constant pressure equilibrium, it becomes ＼.

However, 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, the greater the reduction in gas pressure.

Therefore, the gas sucked into the hollow body 2 has a strong tendency to accumulate in the retention part 15 within the rotation region R of each electric motor 7a, 7b, 7C, and therefore the rotating blade 11 rotating in the part 1b The temperature of the gas is raised under the influence of the frictional heat generation effect. and each electric motor 7a
, 7b, 7c, the frictional heat generated in rotation region 1 is sequentially
The second stage electric motor 7a. Third stage electric motor 7b
, 7c, the temperature rises, and the warm air that has risen to the highest temperature is passed to the final stage electric motor 7C through the gas exhaust port 5.
6 and can be discharged into rooms A and H.

Note that when the three electric motors 7a, 7b, and 7c have the same gas suction and discharge capacity, the pressure at the point from the pressure reducing part 16 formed on the output side of each electric motor 7a, 7b, and 7c to the gas introduction part 12 is the same. It is known that the degree of pressure reduction changes to 1.1/2.173 as the electric motors 7a, 7b, and 7c sequentially move toward each other.

However, since the suction part 16 of the electric motor 7c at the final stage is in communication with the gas discharge port 5.6 of the body 2, the suction gas is forcibly discharged to the outside. It exhibits a pressurizing effect, and therefore generates heat of compression, making it possible to more effectively obtain hot air whose temperature has been increased.

By the way, the air in rooms A and B flows through the rotating body 7 inside the hollow body 2.
As the air temperature in rooms A and H gradually rises by 1, the air temperature in rooms A and H gradually increases.

Furthermore, if a thermostat that can control the temperature of rooms A and B is connected to the rotating body 7 of the hollow body 2 and configured so that it can be turned on and off, constant temperature control of rooms A and B can be easily performed. be able to.

The nine adjacent motion motors 7a, 7b, and 7c rotate in opposite directions to each other to control the flow direction of the gas inside the hollow body 2 in a zigzag manner, resulting in a high heat generation effect and extremely high efficiency. You can make it happen.

However, in the above-mentioned embodiment, the gas inlet side, that is, the gas inlet 3.4 is throttled under reduced pressure equilibrium, and the amount of gas inflow is freely changed to maintain a constant pressure inside the hollow body 2. Although the case described above has been described, hot air can be obtained by constricting the gas outlet side, that is, the gas discharge port 5.degree.6, or by driving the rotating body 7 in the same manner as described above.

In this case, the first stage electric motor 7a inside the hollow body 2
After that, proceed to the second stage and then the third stage.

The space constituted by the suction section 16 and gas introduction section 12 of each of the electric motors 7a, 7b, and 7c constitutes a kind of pressurizing section, and the degree of pressurization of the force 1 gradually increases. , and the pressurized state is the gas flow state, that is,
This results in a dynamic constant pressure equilibrium.

Therefore, the generation of frictional heat is promoted under the constant pressure equilibrium of such pressurization, and as it goes to the first stage, second stage, third stage, and later stage electric motors, the amount of heat generated increases eventually. Where,
υ warm air can be discharged from the gas exhaust ports 5 and 6.

In addition, in both cases of depressurization and pressurization, when starting, the gas inlet 3
, 4. It is also possible to temporarily enhance the heating effect by keeping the gas discharge ports 5 and 6 in a fully closed state under a so-called static constant pressure equilibrium without fluid flow.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can also be implemented with the following configuration, which is not shown in the drawings.

(a) The rotation directions of a plurality of adjacent rotating bodies may be the same direction.

(b) Hollow bodies can be buried not only on walls, but also on floors and ceilings.

(c) The hollow body is an embedded structure! (d) The hollow body can be freely constructed such as a screen type that can stand up or a movable type with a pulley.

(e) The plurality of rotating bodies may not be continuous in a straight line, but may be formed into a two-dimensional hollow body, or may be three-dimensionally formed into a bent structure.

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

This invention is capable of efficiently and constantly extracting clean hot air by the constant pressure equilibrium rotation action of depressurizing or pressurizing the rotating body like an inclined top, and the friction heat generation action, and has a simple structure. It can be provided at low cost because of its 6-cell structure, and is used in various industries such as constant temperature control in indoor heating facilities and hot air control in greenhouse cultivation.

It has effects that can be implemented in a wide range of agricultural fields.
