JP-A-2017-025767

An object to be solved by the present invention is to provide a compressed blower capable of efficiently compressing and sending out air.

In order to solve the above problems, the compression blower of the present invention
The overall internal shape is an onion shape, which has an intake portion, a bulging portion connected to the intake portion and bulging from the intake portion, and an exhaust portion connected to the bulging portion and having a diameter smaller than that of the intake portion. Case and
A rotor blade provided in this case that compresses and sends out the air sucked from the intake portion to the exhaust portion.
It is characterized by being equipped with.

According to this compression blower
The case that houses the rotary blade is connected to the intake part, the bulging part that bulges from the intake part, and the exhaust part that is connected to this bulging part and has a diameter smaller than that of the intake part. Since the overall inner shape is an onion shape, the air sucked from the intake part flows gently and smoothly from the bulging part to the exhaust part, and the diameter of the part is smaller than that of the intake part. Since it is narrowed down to the exhaust section and sent out, it is efficiently compressed and sent out from the exhaust section.
That is, according to this compression blower, air can be efficiently compressed and sent out.

In this compression blower,
The inner surface of the case may be provided with a spiral guide from the intake portion to the exhaust portion.

With this configuration, the air flow from the intake section to the exhaust section can be rectified in a tornado shape, compressed more efficiently, and sent out.

In this compression blower,
An introduction path for introducing a part of compressed air exhausted from the exhaust portion is connected to the intake portion.
The rotary blade may be provided with an assist blade that receives compressed air introduced from the introduction path and assists the rotation of the rotary blade.

With this configuration, a part of the compressed air exhausted from the exhaust portion hits the assist blade through the introduction path, so that an assist force is applied to the rotary blade.
Therefore, the addition acting on the bearing portion that rotatably supports the rotary blade can be reduced, and as a result, the durability of the compression blower is improved.

Hereinafter, embodiments of the compression blower according to the present invention will be described with reference to the drawings. In each figure, the same parts or corresponding parts are designated by the same reference numerals.

As shown in FIG. 1, the compression blower 1 of this embodiment is
It has an intake portion 11, a bulging portion 12 connected to the intake portion 11 and bulging from the intake portion 11, and an exhaust portion 13 connected to the bulging portion 12 and having a diameter smaller than that of the intake portion 11. , Case 10 with an onion-shaped overall internal shape,
A rotary blade 20 provided in the case 10 that compresses and sends out the air sucked from the intake unit 11 to the exhaust unit 13.
It has.

According to this compression blower 1,
The case 10 accommodating the rotary blade 20 is connected to the intake portion 11 and the intake portion 11, and is connected to the bulging portion 12 that bulges from the intake portion 11 and the bulging portion 12, and is connected to the intake portion 11. Since the overall internal shape is an onion shape, which has an exhaust portion 13 having a smaller diameter than that of the exhaust portion 13, the air sucked from the intake portion 11 is gentle toward the exhaust portion 13 from the bulging portion 12. Since it flows smoothly and is narrowed down to the exhaust section 13 having a smaller diameter than the intake section 11 and sent out, it is efficiently compressed and sent out from the exhaust section 13.
That is, according to this compression blower 1, air can be efficiently compressed and sent out.

Further, by forming the case 10 into an onion shape as described above, it is possible to easily take in air inside and prevent air from flowing back from the central bulge (12) toward the intake portion 11.

A spiral guide 14 is provided on the inner surface of the case 10 from the intake portion 11 to the exhaust portion 13.

With this configuration, the air flow from the intake unit 11 to the exhaust unit 13 can be rectified in a tornado shape, compressed more efficiently, and sent out.

As shown in FIG. 22, in the compressed blower 1, an introduction path 15 for introducing a part A3 of the compressed air A2 exhausted from the exhaust unit 13 is connected to the intake unit 11.
The rotary blade 20 is provided with an assist blade 25 that receives the compressed air A3 introduced from the introduction path 15 and assists the rotation of the rotary blade 20.

With this configuration, a part A3 of the compressed air A2 exhausted from the exhaust unit 13 hits the assist blade 25 via the introduction path 15 to apply an assist force to the rotary blade 20.
Therefore, the addition acting on the bearing portion (not shown) that rotatably supports the rotary blade 20 can be reduced, and as a result, the durability of the compression blower is improved.
In FIG. 1 and the like, 21 is the axis of the rotary blade 20.

The guide 14 is formed in a spiral shape with a single groove from the bottom.
The shape of the groove is not just a mountain shape, but one side can be flattened so that the air flow can be directed in a certain direction.

The assist blade 25 has an inclined surface on which the air hits so that the hit air moves toward the exhaust portion 13 as much as possible.

Hereinafter, the compression blower 1 of this embodiment will be described in more detail.

The compression blower 1 of this embodiment is, so to speak, a tornado type blower, which is a device that causes a swirl in the pipe, accelerates the air and discharges it to the outside of the pipe, and produces high-speed air.

Currently, there are compression methods such as reciprocating type and orbital type as the air compression method, but none of them has a large resistance and consumes a lot of energy, but a large effect cannot be obtained. Compressors are used in air conditioners for homes and cars, but they consume a lot of electricity and are inefficient.

Bernoulli's theorem assumes that a non-viscous fluid has a steady flow and no friction, and that the sum of the energies in the fluid is always constant on the streamline. Friction and viscosity prevent the air from moving linearly. To solve this, move the air like a tornado instead of a straight line, and when the air passes through the pipe, it travels a long distance along the side of the pipe, so friction with the pipe is suppressed. , It is possible to speculate that the flow velocity near the center of the tornado will increase. Images of various places when the tornado actually passed are shown, but the passage of the tornado destroys the house and blows away the car.

FIG. 1 is a diagram showing a rotary blade (also referred to as a propeller) 20 that causes a spiral and a case 10 that are combined and the case 10 is halved.
FIG. 2 is a diagram showing a state in which FIG. 1 is viewed from below.

Air is taken in from the bearing in the lower part of FIG.
FIG. 3 is an exploded view of the case 10 and the rotor blade (also referred to as a propeller) 20 as viewed from the front.
A groove (14) for spirally moving the air flow is formed inside the case 10. By making this groove, the air flow in the case 10 is adjusted. This shape creates a layer of air along the groove (14). A groove is formed with this layer of air so as not to obstruct the rapidly moving air generated inside. For this spiral groove, the optimum shape such as shape, depth, pitch, etc. is set.

Reference numeral 23 denotes an upper wing (see FIG. 1), which serves to push air toward the upper exhaust portion 13.
Reference numeral 24 denotes a spiral blade (see FIG. 1), which is a blade that collects air at the center of the outlet to generate a spiral.

FIG. 10 is a diagram showing a shaft 21 of the rotary blade 20 and a bearing portion (a portion connecting the case 10 and the shaft 21).

26 is the lower bearing and 27 is the upper bearing. The shaft 21 of the rotary blade 20 is rotatably supported with respect to the case 1 by the lower bearing and the upper bearing 27.

The shaft 21 is provided with a side-viewing rhombus-shaped upper large-diameter portion 21c and a side-viewing inverted triangular lower-diameter portion 21d, and the upper-diameter portion 21 is provided with an upper wing 23 and a spiral wing 24. The intake blade 22 is provided on the lower large diameter portion 21d.

Since the intake wing 22 is inserted between the upper bearing 27 and the lower bearing 26, the shaft 21 is a lower portion of the upper bearing 27 and can be divided into upper and lower parts.

11 to 18 are views showing the detailed shape of each blade.

As shown in these figures, protrusions 28 and 29 are provided on the blade surface and the blade tip of each blade.
These protrusions 28 and 29 have a shape that is not attached to the propellers of current airplanes or the blades of jet engines. It is considered that the following advantages can be obtained by attaching the protrusions 28 and 29.

It is considered that the protrusions 28 on the blade surface can increase the surface area of the blade surface and increase the amount of air pushed out.
Regarding the protrusion 29 at the tip of the wing, the current propeller makes a sound of cutting the wind when it is turned at high speed, and it is considered that it has a role of reducing this sound.
This mechanism is adopted because the owl's wings have "silence wings".

FIG. 19 is a diagram showing a shaft 21, FIG. 20 is a diagram showing an upper bearing 27, and FIG. 21 is a diagram showing a lower bearing 26.

FIG. 22 is a diagram showing a device for operating the compression blower 1 more efficiently.
In the figure, 21 is a blade shaft, 10 is a case, 30 is a blower pipe, 40 is a pressure tank, and 42 is a control device.

The blade shaft 21 (and therefore the rotor 20) is rotated by a motor (not shown), air is taken into the case 10, a tornado is raised, and the air is discharged from the exhaust port 13 of the case 10. Air is sent to the pressure tank 40 via the blower pipe 30. It is desirable that the inner surface of the blower pipe 30 also has a screw-like shape like the inner surface of a nut so that the tornado generated in the case 10 can be maintained.

The tornado generated in the case 10 increases the velocity of the air. It is thought that air can be blown at a speed of 100 m / S or more. This air pressure of this wind is discharged from the discharge port 41 to serve as a propulsive force and a compressor of an air conditioner.

On the other hand, the introduction path 15 is provided from the pressure tank 40 via a control device 42 that controls the flow rate and pressure of the compressed air A3 to the assist blade 25.

Using this device, it can be expected to be used as a heat pump, drone propulsion force, and air conditioner compressor.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately modified within the scope of the gist of the present invention. For example

When the shape of the case 10 is applied to the intake port of a car (the pipe from the carburetor to the intake valve), the optimum amount of air can be secured without using a turbocharger.

Regarding the surface treatment of both the uneven shape of the case 10 and the uneven shape of the wing, a normal mirror finish may be used, or conversely, it is conceivable that the air flow is smoothed by making the case 10 rough.
