DEVICE FOR SELECTING THE ASPIRATED AIR FLOW BY A CONDITIONING UNIT FOR AMBIENT MEDIA

5

The present invention relates to a device for selecting the flow of air drawn in by a unit for conditioning ambient environments, more particularly a unit of the type installed on a raised floor below which there is air conditioning.

In general, in these devices, motorized flaps, most often arranged vertically, are provided, in order to select the air to be treated and to be introduced into the ambient environment, which however constitute a significant bulk for the other elements of the unit.

This implies the need to provide significant dimensions of the container furniture and creates difficulties for the internal arrangement of the various components.

The object of the present invention is to develop a device for selecting the flow of air sucked in by a unit for conditioning ambient environments which makes it possible to reduce the overall dimensions and to achieve a rational arrangement of the various internal organs.

An object derived from the first consists in making a particularly simple device which ensures precise operation without requiring handling or adjustments.

Yet another object is to produce an inexpensive device, easily adaptable to units for conditioning ambient environments.

The proposed objects and objects are achieved by means of a device for selecting the air flow drawn in by an ambient environment conditioning unit, characterized by the fact of comprising a partition supported laterally by two circular sectors 1 Λ 2 mounted on pivot at their geometric center on the chassis of a unit for conditioning ambient media and each provided on the arcuate edge with a rack on which act two toothed pinions 5 mounted on a motorized axis, said partition thus being able to take two positions, one closing the access way of the air conditioning and the other the way of recycling the ambient air, means being also provided to recall the partition in opposition to the movement of the engine ensuring the operation and to calibrate a " bypass "or bypass of constant inflow of air conditioning.

The characteristics of the invention are described more clearly below by the detailed description of a preferred embodiment, illustrated by way of example in the attached drawing boards in which:

FIG. 1 gives a view of a conditioning unit provided with the device forming the object of the invention in the ambient air suction position;

Figure 2 gives a view of a conditioning unit of the type shown in Figure 1, the device being positioned so as to draw air below the floor;

Figure 3 gives an exploded perspective view of the device and in particular of the partition and its actuating members;

FIG. 4 gives a side view, partially cut away, of the actuating and supporting devices of the movable partition;

And Figure 5 gives a detail of the bypass or bypass and its regulation means.

The invention, illustrated in the mentioned figures-35 born, finds an application in a conditioning unit 1 of the type constituted by a small piece of furniture containing the actuators established on a raised floor 2 below which is 3 ' air conditioning by a refrigeration and treatment unit not shown in the figures.

This conditioning unit is provided with a first opening 3 through which it can suck in ambient air 4 by means of a fan 5 which, before putting it back into the ambient medium, possibly causes it to touch a heating means. 6.

In this state, represented in FIG. 1, the air treated by the unit 1 is practically ambient air 10 which can therefore only be heated by the resistors 6.

The unit also has a second opening. 7 by which it sucks in air 8 from below the raised floor 2.

15 This position is shown in Figure 2.

To allow the selection of the two air 4 or air 8 suction paths, the device which is the subject of the present invention has been devised.

The device consists of a partition 9, preferably metallic and of rectangular shape, supported by two sectors 10 mounted on a pivot on the frame 11 of the unit 1 in a position corresponding to their geometric center.

The pivot mounting is on an axis 12, indicated by an axis line in the figures, around which the two sectors 10 can rotate freely.

The arcuate edge of each of the sectors 10 is provided with a toothed rack 13 on which acts a toothed pinion 1 4 associated with a motorized axis 1 5 rotated by an electric motor 16 provided with a geared motor 17.

The rotation of the electric motor 1 6 causes the angular rotation of the two sectors 1 0 and therefore of the partition 9 which can thus be caused to occlude alter-35 natively the first or the second of the openings indicated respectively by the reference numbers 3 and 7 .

Said support sectors 10 each have, “4 4 in position opposite to the toothed rack 13 and at the level of the pivot mounting axis 12, an insert 18 at the end of which is attached a spring 19 of which the second end 20 is .associated with the chassis of the conditioning unit 1.

The motor 16 therefore acts in opposition to the action of the spring 19 and when the electrical supply is removed from it said springs 19 recall the sectors 10 in the rest position which corresponds to that 10 which is shown in FIG. 1, it i.e. that which corresponds to the intake of ambient air 4.

In this way, when the partition 9 is in the position of occlusion of the opening 3 - as indicated in FIG. 2 - the motor 16, arrived at the end of the race, after having caused the displacement of the sectors 10 , continues to be supplied electrically so as to generate a torque which opposes the elastic return action of the springs 19 during the entire time during which it is necessary to draw air 8 from below the floor.

In this embodiment, the control system and the motor are of an extremely simple type since it is not necessary that the motor be bidirectional or that it is necessary to provide for the presence of an electrical or electronic limit switch capable of '' interrupt the power supply to the motor in a predetermined position.

In practice, if the engine is powered, there is suction of air from below the floor, while if it is not powered there is suction of ambient air.

To ensure a good seal between the partition 9 and the respective suction openings 3 and 7, elastic blades 21 capable of touching the edges of these openings are provided at the long edges of the partition 9.

In these conditioning units, there is always provision for aspiration, however small, Γ; 5 air conditioning from below the floor.

To achieve this, an adjustable end-of-travel wedge 22 has been provided, mounted with a regulating device 23 on which the sectors 5 10 come to bear by the action of the displacement imposed by the return springs 1 9.

The regulation 23 of the corner makes it possible to move it along the arrow 24 so that the elastic blade 21 - as shown in FIG. 5 - comes 10 to be more or less distant from the side panel 25 thus leaving a by- pass or bypass 26 through which air 8 from below the floor is still sucked in one way or another.

It will be noted from what has been described and illustrated that the device is particularly simple as much for the embodiment as for the means serving to operate it.

The choice of a partition supported by two sectors 20 allows it to perform a movement which is always located below the fan 5, which considerably reduces the space required for housing the organs of unit 1 .

The two different positions for the air intake are, as already said, obtained simply either by the action of the electric motor, or by the action of the return springs.

Thus, the command and control devices are greatly simplified since in order to pass from one to the other of the two positions, it suffices simply to power on or to stop the electric motor.

Likewise, regulating the opening of the bypass is particularly simple both from the point of view of production and from the point of view of calibration.

It can be seen from what has been described and illustrated that all of the proposed objectives have been achieved and that a device for 6 al air selection has been produced by a very simple conditioning unit, but at the same time very rational and functional time.

Obviously, starting from the same inventive concept, the shapes of the various organs can be chosen at will according to the necessities.

The materials can also be chosen according to economic convenience.
