    METHODS AND APPARATUS TO PRODUCE LAMINARY FLOW AIR CIRCULATION. The preceding technique has used angled blades connected to a stationary, normally electric motor, to move air within the confines of a structure or room. The preferred invention incorporates a series of solid disks. The disks are attached to a stationary electric motor and thus rotate around a central axis. The discs are equally spaced and centrally perforated in a way that will allow air to flow in high volumes through the perforations and passes along the discs, thus exiting symmetrically between each disc perpendicularly to the air flow at its entrance. Due to the entry of low pressure or less restrictive air, as well as the correct vertical disc spacing, a corresponding increase in laminar flow is achieved. This feature of the preferred invention allows operation at a rotational speed that is practical for use as a ceiling fan.

    DESCRIPTIVE REPORT BACKGROUND OF THE INVENTION
    [0001] The invention revealed in that document maintains a level of human comfort inside a room using the forced movement of air. When temperatures are high, this artificial breeze helps in a cooling sensation as the breeze passes over the person's body.
    [0002] A preferred embodiment of the invention is a ceiling fan. The job on any fan is to convert the motion of the fan, typically the motion of inclined flat blades, into air movement. The preceding technique employs blades rotated by a motor that causes the air movement to create an artificial breeze.
    [0003] Since the middle of the 20th century, systems such as central air conditioning have been incorporated into homes to control the internal temperature of homes during the summer months. Those systems added heating elements to have a unique central system for the home owner. However, limitations in the distribution of heat or cold produced by these systems have demonstrated that an uneven distribution within a room or enclosed area of a structure lends itself to the addition of a ceiling fan to supplement the air circulation within these confinements to the user comfort.
    [0004] As stated, the deficiencies that are part of the heating and / or cooling system have been partially resolved by the use of a ceiling fan that obviously increases the movement of air within the confines of a room, the normal operating state of the fan. ceiling is for its operation to be continuous. This continuous operation occurs while the heating / cooling system is subjected to cycles from operation until its off state.
    [0005] Another benefit of the previous technique's laminated ceiling fan is an overall reduction in energy consumption caused by the ability to change the set temperature of the heating / cooling system to reduce its operating time yet provides the user with the comfort level with a shorter duty cycle of the centralized heating / cooling system.
    [0006] The known physical property of air lends itself to the supplementary aid of a ceiling fan. To be specific, the fact that the colder air that has a higher density will look for a lower level with warmer air rising. The fan of the preceding technique will drive the warmer air down to the ceiling level in an attempt to create a higher state of movement within the confines of a room, thus an attempt to match the distribution of cold air when the cooling system is used. Cooling air source is in use. Most of the prior art ceiling fans incorporate an ability to reverse airflow by reversing the direction of rotation of the fan blades. The purpose of reverse flow is to increase the distribution of hot air, when the central heating feature of the heating / cooling system is being used, during the winter months. During the reverse flow of operation, the warmest air in the ceiling is circulated through the ceiling and the desired results are that this movement creates a circulation that distributes the air in the room more evenly.
    [0007] It is important to note that all ceiling fans of the previous technique try to gain improvements in user comfort by moving air parallel to the vertical surfaces of the room and, thus, perpendicular to the horizontal surfaces of the room. In this way, the motion of air circulation of the preceding technique is limited to a single column of forced air commonly found in the center of the room or, for larger rooms, multiple fans are fixed to the ceiling. For the sake of clarity, we describe a preferred modality, a single unit mounted in the center of a medium room in a typical single-family dwelling.
    [0008] As stated earlier, the sloped blade ceiling fan of the previous technique forces a unique vertical column of air from the descending ceiling to the floor.
    [0009] The preceding technique uses the movement of the single vertical column of air to attack one of the horizontal surfaces of the room, thus requiring an abrupt 90 degree turn of that column of air. This, in turn, creates inefficient turbulent air flow. Therefore, the preceding technique is deficient in the attempt to efficiently circulate the air and to equalize or homogenize the natural hot and cold layers.
    [0010] There is an alternative fan design. In its most basic configuration, it consists of two flat parallel disks. The discs rotate which will rotate the mass of air trapped between the discs. Centrifugal force acts on the air mass and expels it to the outside beyond the edges of the discs and into the surrounding air space. If the discs have some kind of path to allow fresh air to take the place of the expelled air, then the rotating discs will circulate the air. In this way, rotating discs can circulate the air without the need for traditional fan blades.
    [0011] The preceding technique recognized this structure as a "Tesla turbine", a "Prandtl layer turbine" or a "disk-type" turbine. This design has been considered useful only in the context of hydraulic turbines or high pressure air applications, such as vacuum engines or reaction engine turbines.
    [0012] The Tesla turbine was considered impractical in the context of a room fan, because at the standard air pressure of an atmosphere, it was thought, a Tesla turbine simply could not move a sufficient volume of air without being impractically bulky . The device would have required numerous discs, each disc being too large and the discs would have to run at a very high RPM for it to be practical.
    [0013] Surprisingly, current inventors have found a practical design for a disc-type fan operable at standard atmospheric pressures. In fact, as will be seen by a person skilled in the art, the disclosed invention of the disk-type fan is not only practical, but improves fan systems of the prior art. OBJECTS OF THE INVENTION
    [0014] The following disclosure of "objects" of the invention is intended to describe examples or preferred embodiments, to be used in comparison and contrast of the invention with the prior art. This disclosure, however, is not intended to limit the claimed invention in any way.
    [0015] It is, therefore, a general objective of the invention to provide a ceiling fan apparatus that meets the objectives and minimizes limitations of the type previously described.
    [0016] It is a specific objective of the invention to provide a ceiling fan that forces its outlet laterally to the plane of rotation in an increased laminar flow.
    [0017] It is another specific object of the invention to provide complete circulation and mixing of air of different temperatures, when used within the confinement of a room.
    [0018] It is another specific objective of the invention to disperse its high displacement volume of laminar flow air in all directions (360 °) parallel to its plane of rotation.
    [0019] It is another objective of the invention to have air entering the ceiling fan in order not to be obstructed.
    [0020] It is another objective of the invention to have the outgoing laminar flow air expelled without chatter caused by unobstructed inlet air. BRIEF SUMMARY OF A MODALITY PREFERRED PROCEDURE
    [0021] In order to provide a solution to the deficiencies of the prior art, a preferred embodiment of the present invention provides a radial laminar flow ceiling fan, composed of multiple discs (s) stacked approximately equally and having radial symmetry about an axis central. The fan operates by rotating the discs around the central axis. The rotating disc (s) are manufactured in a way that allows unobstructed air to enter from a central opening in the disc (s) and then exit in all directions through spaces equal between the disk array (s) in a high volume of laminar flow, this unique air flow within the room eliminates any dead air when the preferred invention is in use. Attempts by the prior art to obtain increased laminar flow at usual rotational speeds useful for ceiling fans have failed due to the small relative opening of the inlet.
    [0022] Additionally, the preferred invention improves air movement as a result of the wide inlet opening of low relative pressure. As the air returns to the fan, it does so as an inverse cone of expanding rotation. This conical return air has its origin at the lowest point of the room (the floor) with its base expanding to the vertical limits of the room (the walls). The apex of this conical return air is the base of the fan in the inlet opening itself. THE DRAWINGS

    [0034] An improvement over the previous technique is more efficient air circulation. Due to the plurality of discs, their specific size, shape and relative positioning, the fan generates, in a preferred mode, a pattern of laminar air circulation that makes air circulate efficiently throughout a standard room. For example, when the fan is located in the center of the ceiling, the air exits the rotating discs horizontally across the ceiling, spreading evenly in all directions towards the walls of the room as shown in Figure 1. On the walls, the air travels down, parallel to the walls where the air flow turns inwards along the floor and runs back towards the center of the room, see Figure 1 again. Then the air swirls upward in a cyclonic pattern reverse towards an air return opening located at the bottom of the fan as shown in Figure 2. Finally, air enters the fan, through the air return opening, and thus completing the circulation pattern.
    [0035] This air circulation is the result of empirical experimentation in various functional fan designs, each of which combines various characteristics of the fan, in particular the disk dimensions, the disk number and the relative disk positioning.
    [0036] These air patterns result from the fan illustrated in Figure 3 which is a built-in laminar flow ceiling fan also shown in exploded view in Figure 4 below. The horizontal arrows 407 show the air leaving the fan beyond the edges of the slave disks 401. The return air 406 is shown entering the fan through a central air return opening, see also Figure 5 103. As the air enters on the fan it is smoothly directed outwards by the conical-shaped part 408 of the main command disk described in more detail in Figure 8 below. This new feature, directing an air stream in and out of a fan without significantly disturbing the laminar flow of that air stream, is a unique property completely absent from the prior art.
    [0037] The embodiment of Figure 3 comprises a main or command disk 405 mounted above an array of eight (8) slave disks 401 below. The through screws 402 attaching the main disk to the slave disks are threaded through vertical spaces 403 that keep the slave disks 401 parallel and spaced at a predetermined distance. The main disk also has a smooth, invented cone shape that directs air entering through the air inlet path 406 to the laminar flow outlet 407 shown on the die side.
    [0038] Figure 4 is an exploded view of the complete fan. The electric motor is 501. The through screws 502 run through the entire matrix, linking the entire slave disk matrix to the main command disk 503 and terminate at the connection and retaining ring 504. The base air guide 505 covers the assembly of 506 motor mounting screw during fan operation, but can be removed during fan assembly and maintenance. This set connects the motor 501 to the main command disk 503.
    [0039] The complete slave disk array 507 and the main command disk 503 are shown mounted and attached to the stationary drive motor 501 by fixing five (5) machine screws through the main command disk motor mounting screw holes 506 completing the construction of the preferred invention. Motor 501 rotates the entire main command disk and slave disk array 503 and 507 respectively.
    [0040] Figure 5 is a top view of a single slave disk 101 of a preferred embodiment. Each slave disk is preferably injection molded from raw plastic and manufactured identically with a circular opening. An air inlet cavity 103 is present in the center of each disc. Each disc in the fan will have this cavity. When the discs are stacked together as shown in Figure 3, the air inlet cavities will create an air return opening into which air will flow 406 as will be explained more fully below.
    [0041] The slave disk 101 is preferably manufactured by plastic injection molding in order to create smooth surfaces on both sides. A smooth surface is a preferred surface for promoting laminar flow over a rotating disc (s) 101. Of course, any surface designed to promote laminar flow will work in the invention. This is particularly true in cutting-edge projects where advanced aeronautical engineering can be employed.
    [0042] The diameter of the air inlet cavity 103 is derived with the following equations. The inner diameter of the disc (ID) is a function of the surface area (A) of a single disc as follows: ID = ^ AO The outer diameter (OD) of the slave disc 105 is determined as follows: OD 1 1.5 x ID or, more precisely:
    Obviously, some variation in the exact ID: OD ratio is permissible. In fact, under specific conditions (room size, atmospheric pressure) some tests can be performed and variations of 2, 5, 10 and up to 15 percent may be necessary to achieve optimal performance.
    [0043] In a preferred embodiment, the surface area (A) is about 500 square inches, the outside diameter (OD) is about 34 inches and the inside diameter (ID) is about 23 inches.
    [0044] The ideal number of disks in the 301 matrix has been determined. The fan works more efficiently as the number of slave disks increases from one (1) to eight (8). (Note, if the main disk is included, then this range is from two (2) to nine (9).) In the preferred mode, there is a marginal but significant increase in efficiency, as the disks in the matrix are increased from seven (7) to eight (8). Surprisingly, eight appears to be an upper limit, since no increase in efficiency is observed when the number is increased beyond eight.
    [0045] Item 102 describes an integral spacer with an aerodynamic or vertical cylindrical shape. The space between discs, the vertical dimension (V), is a function of the outer diameter of the disc (OD) and inner diameter (ID) as follows: V = (OD - ID) x 0.0625 In a preferred embodiment, the dimension vertical (V) is 0.75 inches.
    [0046] Although the preceding formula provides a useful solution for designing a modality of the claimed invention, there is undoubtedly an admissible variance in the vertical dimension, but it is surprisingly small. We estimate that laminar flow will persist as the vertical distance is increased by about 10 percent, but will cease after the vertical distance is increased by 100 percent. Obviously, for cutting-edge uses, the maximum vertical dimension limit for a particular modality can be determined by experimenting with brute force. Simply build several fans with different vertical dimensions until you find the ideal distance for which laminar flow predominates over turbulent flow and maximizing the volume of air moved.
    [0047] Figure 6 is a vertical cross section of the spacers. A set of spacers is distributed around the slave disk in a uniform circular pattern at a distance that is, in a preferred embodiment, one third (1/3) of the distance from the disk ID to the disk OD. In a preferred embodiment, a total of 10 integral vertical spacers are molded along the arc represented by the dashed line 104 in Figure 5 and also dispersed as described above.
    [0048] Figure 6 illustrates a preferred design taking into account the vertical stacking of the spacers. As described above, spacer (s) 102 provides for uniform vertical separation by and between each disk in the slave disk array 401 and has a central hole 102a that allows through screw 402, 502 to pass through the disk array. In addition, the integral spacer has an alignment and coupling connection cavity 101b that conforms to and accepts the vertical spacer counterpart 102b which will result in the next successive disc resting on the shoulder 103b of the vertical spacer.
    [0049] Figures 7A-D illustrate a laminar airfoil vane that can optionally be connected to the vertical spacers of Figure 6. Figure 7A is an axonometric view. Figure 7B is a top view. Figure 7C is a front view and Figure 7D is a right side view. The height 703 of each vane 701 is less than that of the vertical spacer to which the vane is mounted and the diameter of the mounting hole 702 is slightly greater than the outer diameter of the vertical spacer. Taken together, these characteristics allow the reed to rotate freely. The entire vane can change its angle of attack to align with the incoming laminar air movement which can vary from time to time, due to changes in air speed, RPM engine loads, etc. These vane 701 increase the outgoing air velocity due to the centrifugal force of a vertical vane rotating and placed in the path of the incoming laminar flow air. The effect is similar to that of taking a flat piece of cardboard and waving it in front of someone's face to create a cooling breeze.
    [0050] The reed as illustrated is a preferred modality and can take different forms depending on the type of laminar airfoil desired. The vanes can also be made stationary, if desired.
    [0051] Figure 8 is a representation of the upper main command disk 301 that provides the connection base for the slave disk array 401 and the drive motor through the motor mounting holes 303. The main disk 301 is preferably molded as a single piece. The main command disk 301, in axonometric view, shows the screw through holes 302 which allows the screw to pass through and connect the retaining ring of connection 201. Note that the alignment cavity 304 is in accordance with the model identical to that of the Figures 5 and 9 so that through screws and vertical spacers 102 can pass from the upper disk through the die to the retaining ring at the bottom of the fan. Note again that the main command disk has a conical shaped air guide 305 that aids air intake as well as increasing the laminar flow by providing an unobstructed air passage into and out of the rotating disk array.
    [0052] Figures 9 and 10 illustrate the retaining ring and retaining ring screws, respectively. The connection retaining ring 201 is shown in the top view. The purpose of the retaining ring is to receive the screws that pass through the main command disk 301, see Fig. 8, and each slave disk 101 in the disk array. Figure 10 shows a retaining and aligning ring screw receiving cylinder 201a, 202a designed to gap within the lower slave disk 101 and is formed to accept the threaded screw through a central hole 102a of the screw receiving cylinder . These retaining screws are distributed in a pattern that will match that of the integral vertical spacers 201. This pattern is represented by the dashed line 203. The screw receiving cylinder 201a is conformed to the alignment cavity 101b at the bottom of the screw. The connection retaining ring 201 is affixed to the lower disk of the matrix 401 so that its top surface is flush with the lower disk.
    [0053] The preferred invention as a unit will have the number of disks as described by the aforementioned equation. The operating rotational speed of the preferred invention is within the normal range for a conventional ceiling fan. The 501 engine is designed to accommodate various speeds depending on the user's desired rate of laminar flow air. The formula below can be used to describe the force of airflow. This is defined as the difference in pressure generated by the air exiting the fan over the surrounding air pressure, (P2 - P1).
    where "fluid density" is the standard air density and R2 and R1 are the distances to the outer edge of the disc and the inner edge, respectively, as measured from the center of the rotating disc.
    [0054] As described above, the airflow patterns of prior art fans are inefficient. They are generally limited to creating a single column of air column that displaces the surrounding air. The size of this air column is limited by the diameter of the blades that rotate around the fan hub. The air column also comes out of a fan located in the center of the room, in a typical installation, where the air column has a limited effect at any point lateral to that air column until contact is made with a horizontal surface of the room. During the summer, the air column, which is slightly colder and denser than the surrounding air, will deflect downwards, which will allow hot air to gather near the ceiling, a very inefficient way to cool a room. living room.
    [0055] In describing the invention, reference is made to preferred embodiments and illustrative advantages of the invention. Those skilled in the art and familiar with the impending disclosure of the invention in question may recognize additions, deletions, modifications, substitutions and other changes that fall within the competence of the invention in question and Claims.
    [0056] For example, one of the modalities described above has eight (8) disks in the matrix as an ideal number. This matrix size, however, is dependent on the fan being designed for home use in a full-sized room. However, there is no theoretical reason why a fan is this particular size. In fact, given the appropriate budget, a fan array suitable for large industrial spaces can be designed. In these applications, the air return opening would be larger and the ideal number of discs in the array could be much larger. These larger disks would probably be more expensive to manufacture. The discs would be subject to greater centrifugal forces and this, in turn, would require proportionally stronger, more expensive materials. However, there are no theoretical problems in building a matrix that could handle a large warehouse or an airplane hangar.
    [0057] In addition to the design features described above, the inventors specifically see that any dynamic air feature that promotes laminar flow will be useful in certain embodiments of the claimed invention. This description mentioned only a few cost-effective features. Depending on the budget available, additional features are also appropriate. SUMMARY OF THE MAIN ADVANTAGES OF THE INVENTION
    [0058] After reading and understanding the above-mentioned detailed description of an inventive laminar flow ceiling fan according to preferred embodiments of the invention, it will be seen that several distinct advantages of the laminar flow ceiling fan in question are obtained.
    [0059] At least some of the biggest advantages include providing a 401 disk matrix made of plastic and injection molded with integral vertical spacers. The disk array is easily constructed without a template due to the integral vertical spacers 102 that allow vertical stacking of the disks to be performed. The completed disk array 401, when rotated by drive motor 501, will allow unobstructed air to enter through open air inlet 406 and expel laminar flow air at a high volume and lower RPM, relative to the preceding technique, in all the directions 360 degrees parallel to the direction of rotation. When used and in relation to ceiling fans of the prior art, the induced circulation of the preferred invention homogenizes the air inside the room to further cause the temperature distribution of the heated or conditioned air inside without any change in its direction of rotation.
