Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a constant pressure equilibrium rotary heating device which has no energy loss and is extremely efficient.

[Conventional technology]

The inventors of the present invention have developed a system in which a heat-generating phenomenon due to friction with gas is generated in a cylindrical casing or a hollow chamber in which a rotating body is disposed in a constant pressure equilibrium state of depressurization or pressurization based on the rotational action of a rotary body. The heated gas inside the cylindrical casing or hollow chamber is discharged to the outside,
Alternatively, the inventors have completed a series of inventions in which the cylindrical casing or hollow chamber itself is heated and used as a heat source, thereby making it possible to obtain an effective and clean heat source inside and outside the cylindrical casing or hollow chamber.
That is, to give an example of the main ones, Special Publication No. 59-52342, Special Publication No. 52753-1983, and Special Publication No. 59-59-
47821, the first invention in JP-A No. 59-9822, the first invention in JP-A-59-4625, JP-A-58-

No. 60-196554, etc.

The inventions of these earlier applications are characterized in that the gas inside the cylindrical casing or the hollow chamber is heated by the main frictional action of the rotating body, and whether it is depressurized or pressurized. Regardless of the situation, it is effective not only in a state where the gas is sealed in a cylindrical casing or hollow chamber under a desired constant pressure (static state), but also in a state where the gas is flowing under a desired constant pressure (dynamic state). The technical content is to generate heat.

[Problem that the invention seeks to solve]

Based on the above-mentioned basic technical idea, the inventor of the present invention intended to create a highly efficient constant-pressure equilibrium rotary heat-generating device by minimizing the energy consumed by the rotating body that performs the heat-generating action.

[Means for solving problems]

That is, in this invention, a rotary body driven by an electric motor and having a suction/exhaust function is disposed inside a desired cylindrical casing, and an annular weir plate is disposed at the front and back of this rotary body, or on either side of the rotary body to form a pressure regulating chamber. By doing so, the electrical energy consumed by the electric motor is significantly reduced.

Note that the number of rotating bodies attached to the electric motor is not limited to one, but it is also possible to arrange a plurality of rotating bodies in a row to form a multi-stage structure.

The pressure regulating chamber is formed by providing an annular weir plate, and by making the opening degree of the weir plate provided on the exhaust side adjustable, the pressure regulating state can be variably adjusted to find the optimum conditions during use. Can be set.

Further, the annular weir plate on the intake side constituting the pressure regulating chamber is provided with a guide tube along the inside so as to obtain an effective guide effect when gas flows in.

[Effect]

As described in the inventions of the publications listed above, the rotating body is arranged in a cylindrical casing and rotates so as to maintain a constant pressure equilibrium state of depressurization or pressurization inside the cylindrical casing. Therefore, it exhibits a heat-generating effect due to effective friction with the gas, and the inside of the cylindrical casing can be heated to the required temperature, and the heated gas is exhausted to the outside from the exhaust port.

By the way, the rotating body is distinguished by annular weir plates installed at the front and back or on either side of the cylindrical casing, and because it faces the pressure regulating chamber, the pressure reduction effect increases, the gas density decreases, and the gas resistance decreases. Therefore, the energy applied to the electric motor that drives the rotating body, that is, the power consumption, can be significantly reduced.

That is, the reduced pressure state of the pressure regulating chamber can reduce the rotational torque of the rotating body, and as a result, the electrical energy acting on the electric motor can be reduced.

If the weir plate is installed on the front intake side of the cylindrical casing, the consumption of electric energy can be reduced considerably, but on the other hand, if it is only adjacent to the rear exhaust side of the rotating body, the above configuration It has been experimentally found that it is possible to further reduce the consumption of electrical energy, and that when the rotor is provided at two locations, the front and rear of the rotating body, the power consumption can be significantly reduced compared to the former two.

Furthermore, when a guide tube is provided inside the weir plate on the intake side, the effect of inflowing suction fluid is high, and by combining with the above configuration, power consumption can be reduced more than the above.

〔Example〕

Examples of this invention are shown below.

First, the basic structure shown in FIG. 1 will be explained.

1 is a cylindrical casing having an intake port 2 and an exhaust port 3; 4 is a rotating body rotatably disposed within the cylindrical casing 1 and has an intake/exhaust function; 5;
is firmly fixed in the cylindrical casing 1 via the supporting leg 6 by the electric motor of the rotating body 4. The rotating body 4 is
It is equipped with a rotating vane such as a propeller fan or a shirotsukofan that has a desired inclination angle and has a suction/exhaust function. Reference numeral 7 indicates an annular weir plate disposed on the rear exhaust side of the rotating body 4, and forms an annular slit S between it and the electric motor 5. Reference numeral 8 indicates an annular weir plate disposed on the intake side of the rotating body 4, and both weir plates 7,
A pressure regulating chamber 9 is formed between 8 and 8.

Note that either one of the weir plates 7 and 8 may be omitted, and even in this case, a pressure regulating chamber 9 is formed in relation to the rotating body 4.

The rotating body 4 facing into the pressure regulating chamber 9 has a suction/discharge function, and forms a small gap g between it and the cylindrical casing 1 to form a reduced pressure equilibrium heating mechanism A.

Furthermore, on the exhaust side, it is more effective to form the cylindrical casing 1 into a conical part 10 whose diameter is gradually narrowed as much as possible, when the weir plate 7 at the rear of the rotating body 4 is omitted.

Reference numeral 11 denotes a guide tube portion provided along the inner end of the annular weir plate 8 provided on the intake port side.

The effect of the above structure will be explained.

The rotating body 4 starts to rotate when the electric motor 5 is energized, and as a result, gas is sucked in from the intake port 2 and a depressurized equilibrium heating action is performed in the pressure regulating chamber 9, raising the gas temperature to a desired temperature. The gas that has been heated and heated is discharged from the exhaust port 3 to the outside.

In this case, the rotational action of the rotating body 4 is carried out within the pressure regulating chamber 9, which is composed of an annular dam plate 8 provided on the opening side of the intake port 2 and an annular dam plate 7 provided at the rear of the rotating body 4. As a result, the depressurizing effect increases in front of the rotating body 4, but a kind of pressurizing effect works behind the rotating body 4, and the swirling laminar flow of gas, which is partially blocked by the annular weir plate, reduces the pressure of the backlash. This increases the rotational action of the rotating body 4 from behind, and gas resistance acts on the rotating body 4 due to the gas environment in front of the rotating body 4 where the gas density is low in a reduced pressure state. As a result, the power consumption for the rotating body 4 is significantly reduced, and significant economic efficiency can be ensured.

Note that the pressure reduction effect and the gas inflow effect can be improved by the annular weir plate 8 and the guide tube part 11 provided inside the weir plate 8 at the intake port 2, so that the pressure regulation inside the pressure regulation chamber 9 can be improved. The situation is further improved, and the energy applied to the electric motor 5 can be further saved.

By the way, of the two weir plates 7 and 8, if the intake side is removed and only the one behind the rotating body 4 is left, the power consumption will be lower than if the intake side is left and the one behind the rotating body 4 is removed. The savings are huge.

This is because the weir plate 7 at the rear of the rotating body 4 acts as a kind of obstruction plate for the gas in the exhaust gas, causing a pressurization phenomenon that is contrary to the depressurization, but this pressurization phenomenon acts as a reaction to the rotating body 4. This backlash effect promotes the rotation of the rotating body 4 and reduces the amount of current applied to the electric motor 5.

Next, the actual concrete configuration of the embodiment shown in FIG. 2 will be explained.

Components that are the same as or correspond to those in FIG. 1 are designated by the same reference numerals, and redundant explanation will be omitted.

The cylindrical casing 1 is composed of an intake side casing 1a and an exhaust side casing 1b which can be divided approximately at the center, and an annular dam plate 7 is interposed between the flanges of the overlapping part of both casings 1a and 1b. Then, the opening degree of the annular slit S can be adjusted by replacing the weir plate 7 of your choice with a different inner diameter, or by fixing the annular weir plate 7 whose inner diameter can be freely adjusted to a large or small size. be.

Further, an annular weir plate 8 having a guide tube 11 provided inside is fixed to the open end of the intake port 2 via a ring tube 12. Similarly to the weir plate 7, the weir plate 8 having the guide cylinder portion 11 can be replaced, or the diameter can be varied by adjusting the aperture so that it can be narrowed and expanded.

The electric motor 5 is covered with a casing 13 to form an annular tubular flow path 14 between it and the casing 1b, and the supporting legs 6 function as a guide plate.

Since the configuration described above is adopted, as in the embodiment shown in FIG.
Power consumption can be reduced.

〔Effect of the invention〕

According to this invention, a pressure regulating chamber is formed in a cylindrical casing in which annular weir plates are provided before and after the rotating body and an intake port and an exhaust port are bored, so that the pressure reduction effect is extremely effective, and moreover, the swirling laminar flow is The power supply to the electric motor for driving the rotating body is significantly reduced due to the backlash effect, thereby increasing the economic effect. Therefore, it is suitable for various consumer electrical appliances, such as heating appliances such as ventilation fans, hair dryers, and hot air blowers.
