Description

The present invention relates to a home automation installation comprising a concealment device, a ventilation device and a device for controlling the ventilation device.

The present invention also relates to a control method in operation of the home automation system.

In general, the present invention relates to the field of occultation devices comprising a motorized drive device moving a screen between at least a first position and at least a second position.

A motorized drive device of a home automation installation comprises an electromechanical actuator of a movable closure, occultation or sun protection element, such as a shutter, a door, a blind or any other equivalent equipment, called by the following screen.

We already know the document DE 199 63 919 A1 which describes a home automation installation comprising a concealment device, a ventilation device and a device for controlling the ventilation device. The occultation device is a roller shutter.

The concealment device comprises a screen and a motorized drive device. The motorized driving device comprises an electromechanical actuator for raising and lowering the screen between a high position and a low position. The ventilation device comprises an air inlet member with a controllable air passage section. The air intake member comprises an air flow duct and a shutter shutter of the air duct. The ventilation device control device comprises a first subassembly connected to the screen and a second subassembly connected to the shutter flap of the air inlet member. The first subassembly cooperates with the second subassembly during a displacement of the screen implemented by the motorized drive device, so as to control the positioning of the closing shutter of the input member of air with a controllable air passage section.

However, this home automation installation has the disadvantage of coupling the first subassembly, connected to the screen, with the second subassembly, connected to the shutter flap of the air intake member, by means of a cable system. The first subassembly is disposed at the final blade of the screen and configured to hook with the cable system in a ventilated position of the screen, so as to allow a flow of air from a space between the final blade of the screen and the threshold of the opening, which can be closed by the screen, then to the ventilation device in the upper part of the frame from the window.

Therefore, this home automation system has a device for controlling the complex ventilation device that is necessary to allow the cooperation of the first subset with the second subset.

In addition, the control cable system of the second subassembly by the first subassembly is visible and unattractive, since it is arranged between the screen of the concealment device and an outer face of a window installed near this occultation device.

The cost of obtaining the home automation system is therefore high, because of the control cable system of the second subset by the first subset.

Furthermore, the control cable system of the second subassembly by the first subassembly requires the transmission of a force through the screen, in particular by plating the blades of the screen against each other.

Therefore, following the positioning of the screen in the ventilation position, the openings between the blades of the screen are removed and the light from outside does not cross the screen and therefore the window.

The control cable system of the second subassembly by the first subassembly operates only in a single position of the screen, namely the ventilation position, in which the final blade of the screen is located. near the threshold of the opening.

The present invention aims to solve the aforementioned drawbacks and to propose a home automation installation comprising a shading device, a ventilation device and a device for controlling the ventilation device making it possible to simplify the control of a second subassembly, connected to a shutter of an air inlet member with controllable air passage section, by a first subassembly, connected to a screen of the occulting device.

We first describe, with reference to Figures 1 and 2 , a home automation system according to the invention and installed in a building comprising a shading device and a ventilation device.

The home automation system comprises an opening 1 equipped with a screen 2 belonging to a concealment device 3, in particular a motorized roller shutter.

The concealment device 3 may be a rolling shutter, a fabric blind or with adjustable blades, or a rolling gate. The present invention applies to all types of occulting device.

In addition, a window 30 is disposed at the opening 1 formed in the building. For the sake of clarity, the window 30 is omitted at the figure 2 .

The window 30 comprises at least one opening 31 and a fixed frame 32, as illustrated in FIGS. Figures 4 to 6 .

The window 30 comprises a single opening 31.

The number of openings of the window is in no way limiting and may be different, in particular equal to two. In such a case, the two openings cooperate together, in particular when they are brought into a closed position relative to the fixed frame.

The opening 31 comprises a frame. The opening 31 may also include at least one window arranged in the frame of the opening.

The number of windows of the opening is not limiting and may be different, in particular equal to two or more.

Here, the screen 2 is disposed on the outside of the window 30, in the assembled configuration of the home automation system.

The screen 2 of the occulting device 3 is wound on a winding tube 4 driven by a motorized drive device 5 and movable between a wound position, particularly high, and a unwound position, particularly low.

The movable screen 2 of the concealment device 3 is a closure, concealment and / or sun protection screen, winding on the winding tube 4, the internal diameter of which is substantially greater than the external diameter of a electromechanical actuator 11, so that the electromechanical actuator 11 can be inserted into the winding tube 4, during assembly of the occulting device 3.

The motorized drive device 5 comprises the electromechanical actuator 11, in particular of the tubular type, making it possible to rotate the winding tube 4, so as to unroll or wind up the screen 2 of the occulting device 3.

In known manner, the shutter, which forms the occulting device 3, comprises an apron comprising horizontal blades articulated to each other, forming the screen 2 of the shutter 3, and guided by two lateral rails 6. These blades are joined when the deck 2 of the shutter 3 reaches its low position unrolled.

In the case of a shutter, the wound up position corresponds to the support of a final L-shaped end plate 8 of the deck 2 of the shutter 3 against an edge of a box 9 of the shutter 3, and the lowered low position corresponds to the support of the final end blade 8 of the deck 2 of the shutter 3 against a threshold 7 of the opening 1.

The first blade of the apron 2 of the shutter 3, opposite to the final end blade 8, is connected to the winding tube 4 by means of at least one hinge 10.

The winding tube 4 is disposed inside the trunk 9 of the roller shutter 3. The apron 2 of the roller shutter 3 winds and unwinds around the winding tube 4 and is housed at least in part at the inside the trunk 9.

In general, the box 9 is disposed above the opening 1, or in the upper part of the opening 1.

The motor drive device 5 is controlled by a control unit. The control unit may be, for example, a local control unit 12, where the local control unit 12 may be wired or wirelessly connected to a central control unit 13. The central control unit 13 controls the local control unit 12, as well as other similar local control units distributed throughout the building.

The central control unit 13 may be in communication with a remote weather station outside the building, including, in particular, one or more sensors that can be configured to determine, for example, a temperature, a brightness, or a speed Wind.

A remote control 14, which can be a type of local control unit, and provided with a control keyboard, which includes selection and display elements, also allows a user to intervene on the actuator electromechanical 11 and / or the central control unit 13.

The motorized drive device 5 is preferably configured to execute unwinding or winding control commands of the screen 2 of the concealment device 3, emitted in particular by the remote control 14.

We now describe, in more detail and with reference to the figure 3 , the electromechanical actuator 11 belonging to the home automation system of Figures 1 and 2 .

The electromechanical actuator 11 comprises an electric motor 16. The electric motor 16 comprises a rotor and a stator, not shown and positioned coaxially around an axis of rotation X, which is also the axis of rotation of the tube. winding 4 in mounted configuration of the motorized drive device 5.

Control means of the electromechanical actuator 11, allowing the displacement of the screen 2 of the concealment device 3, comprise at least one electronic control unit 15. This electronic control unit 15 is able to put into operation the engine 16 of the electromechanical actuator 11 and, in particular, to allow the electrical power supply of the electric motor 16.

Thus, the electronic control unit 15 controls, in particular, the electric motor 16, so as to open or close the screen 2, as described above.

The electronic control unit 15 also comprises an order receiving module, in particular radio orders issued by a command transmitter, such as the remote control 14 intended to control the electromechanical actuator 11 or one of the local control units 12 or central 13.

The order receiving module, which is not shown, can also allow the reception of orders transmitted by wire means.

Here, and as illustrated in figure 3 , the electronic control unit 15 is disposed inside a casing 17 of the electromechanical actuator 11.

The control means of the electromechanical actuator 11 comprise hardware and / or software means.

By way of non-limiting example, the hardware means may comprise at least one microcontroller.

The electromechanical actuator 11 is supplied with electrical energy by a mains power supply network, or by means of a battery, which can be recharged, for example by a photovoltaic panel. The electromechanical actuator 11 makes it possible to move the screen 2 of the occulting device 3.

Here, the electromechanical actuator 11 comprises a power supply cable 18 for its supply of electrical energy from the mains power supply network.

The housing 17 of the electromechanical actuator 11 is preferably of cylindrical shape.

In one embodiment, the housing 17 is made of a metallic material.

The housing material of the electromechanical actuator is not limiting and may be different. It may, in particular, be a plastic material.

The electromechanical actuator 11 also comprises a gear reduction device 19 and an output shaft 20.

The electromechanical actuator 11 may also comprise an end-of-travel and / or obstacle detection device, which may be mechanical or electronic.

Advantageously, the electric motor 16 and the gear reduction device 19 are disposed inside the casing 17 of the electromechanical actuator 11.

The output shaft 20 of the electromechanical actuator 11 is disposed inside the winding tube 4, and at least partly outside the casing 17 of the electromechanical actuator 11.

The output shaft 20 of the electromechanical actuator 11 is coupled to the winding tube 4 by a connecting element 22, in particular a wheel-shaped connecting element.

The electromechanical actuator 11 also comprises a shutter element 21 at one end of the casing 17.

Here, the casing 17 of the electromechanical actuator 11 is fixed to a support 23, in particular a cheek, of the trunk 9 of the concealment device 3 by means of the closure element 21 forming a torque support, in particular a shutter head and torque recovery. In such a case where the shutter member 21 forms a torque support, the shutter element 21 is also called the "fixed point" of the electromechanical actuator 11.

We describe, with reference to Figures 4 to 6 , a ventilation device belonging to the home automation system illustrated in Figures 1 to 3 .

The ventilation device 24 comprises at least one air inlet member 25 with a controllable air passage section.

Thus, a flow of air F can flow between the outside and the inside of the building, in particular from the outside to the inside of the building, through the air inlet member 25, in particular, following the positioning of the air inlet member 25 in an open configuration, as illustrated in FIG. figure 5 .

Here, the air intake member 25 is integrated with the window 30, in particular with the opening 31 of the window 30.

In a variant, the air inlet member 25 is integrated with the fixed frame 32 of the window 30.

Alternatively, the air inlet member 25 is disposed in a wall of the building near the window 30, facing the screen 2.

In practice, the air inlet member 25 is disposed at a wall of the building, so as to create a direct fluid communication between the outside and the inside of the building.

The wall of the building may advantageously correspond to a portion of the window 30, in particular the opening 31 or the fixed frame 32.

Thus, the flow of air through the air inlet member 25 is implemented between an outer face of a building wall and an inner face of the same wall of the building.

The outer face of a wall of the building may be an external facade of a wall of the building. And the inner face of a wall of the building may be an internal facade of a building wall.

In practice, the air inlet member 25 is of elongated shape and allows easy mounting in a cutout formed, for example, in a frame of the window 30.

In one embodiment, not shown, the air inlet member 25 may be disposed through a wall of the building.

In such a case, the air intake member 25 may comprise sound insulation means, so as to limit the passage of noise from the outside of the building to the interior of the building.

The air intake member 25 is thus disposed opposite the screen 2, the screen 2 is placed inside the opening 1 or it is placed at the outside the building and covers the opening 1.

The air inlet member 25 comprises an air circulation duct 26. The air duct 26 comprises an air inlet opening 27 and an air outlet opening 28.

Thus, the air flow duct 26 of the air inlet member 25 circulates the air between the air inlet opening 27 and the air outlet opening 28. .

In one embodiment, the ventilation device 24 also comprises at least one fan, not shown. The flow of air between the air inlet opening 27 and the air outlet opening 28 through the air flow duct 26 of the air inlet member 25 is then implemented through the fan.

The fan can either be integrated in the air inlet member 25, or be placed outside the air inlet member 25, such as, for example, a fan of a mechanical ventilation device controlled, also called "VMC", which generates an air depression between the inside of the building and the outside of the building.

Alternatively, the flow of air outside the building from the air inlet opening 27 to the air outlet opening 28 through the air flow duct 26 of the input member air 25 is implemented by any other device generating an air depression between the interior of the building and the outside of the building.

In such a case, where the circulation of outside air entering the building is implemented by another device generating an air depression between the interior of the building and the outside of the building, this other device for generating depression can be implemented according to the principle of natural convection, using, in particular, chimneys, or elements generating a fluid flow according to the principle of the Venturi effect.

The air inlet member 25 comprises a shutter 29, for selectively closing the air flow duct 26.

The shutter 29 of the air inlet member 25 may be disposed outside or inside the air flow duct 26, or in the vicinity of the opening air inlet 27 formed at the end of the air duct 26 located at the outer face of the wall of the building.

Here, the shutter 29 of the air inlet member 25 is rotatable and rotatable about an axis of rotation Y.

Preferably, the axis of rotation Y of the shutter 29 relative to a body of the air inlet member 25 is located along an upper edge of the shutter 29.

In this case, the axes of rotation X, Y are parallel.

Thus, a lower end of the shutter 29 is moved in a rotational movement from the bottom upwards, during the passage of the shutter 29 from a closed position to an open position of the circulation duct of air 26.

In this way, this position of the axis of rotation Y of the shutter 29 makes it possible to prevent water infiltration by runoff inside the air inlet member 25 and, in particular, in the air circulation duct 26.

In addition, this position of the axis of rotation Y of the shutter 29 makes it possible to evacuate by gravity any splashing water, in particular during a rainy weather.

The shutter 29 makes it possible to adjust the area of the air passage section of the air circulation duct 26.

In this way, the shutter 29 constitutes a means of controlling the opening of the air passage section of the air flow duct 26.

In one embodiment, the shutter 29 may make it possible to modulate the opening of the air passage section of the air flow duct 26 between an open position, corresponding to a value of 100% of the maximum area of the air passage section at the shutter 29, and a closed position, corresponding to a value of 0% of this area.

The closed position may be a position allowing a minimum flow of the air flow F through the air circulation duct 26 of the air inlet member 25. Alternatively, this closed position may be a position preventing completely the flow of the air flow F through the air flow duct 26 of the air inlet member 25.

A control device 33 of the ventilation device 24 comprises a first subassembly 34 connected to the screen 2 and a second subassembly 35 connected to the shutter 29 of the air inlet member 25.

The first subassembly 34 cooperates with the second subassembly 35 during a displacement of the screen 2 implemented by the motorized drive device 5, so as to control the positioning of the shutter shutter 29 of the air inlet member 25.

The first subassembly 34, connected to the screen 2, comprises at least one magnetic element 36. And the second subassembly 35, connected to the shutter 29 of the air inlet member 25, comprises at least one other magnetic element 37.

Here, and as illustrated in Figures 4 to 6 the first subassembly 34 and the second subassembly 35 each comprise a single magnetic element 36, 37.

The number of magnetic elements of the first and second subsets is in no way limiting and may be different, in particular equal to two.

In a preferred embodiment, the magnetic element 36 of the first subassembly 34 is aligned horizontally with respect to the magnetic element 37 of the second subassembly 35, according to the width of the concealment device 3 and in the assembled configuration. of the home automation system.

In one embodiment where the first subassembly 34 comprises a single magnetic element 36, the latter is disposed centrally along the width of the screen 2. And the second subassembly 35 also comprises a single magnetic element 37 disposed in central position along the width of the shutter 29 of the air inlet member 25.

In another embodiment where the first subassembly 34 comprises two magnetic elements 36, these are arranged along the width of the screen 2 with a predetermined spacing. And the second subassembly 35 also comprises two magnetic elements 37 arranged along the width of the shutter 29 of the air inlet member 25 with the same predetermined spacing for the magnetic elements 36.

Preferably, the magnetic element 36, 37 of the first and second subassemblies 34, 35 is a magnet.

The magnetic element 36 of the first subassembly 34 cooperates with the magnetic element 37 of the second subassembly 35, so as to modify the position of the shutter 29 of the air inlet member 25, when the magnetic element 36 of the first subassembly 34 is displaced from a position offset from the magnetic element 37 of the second subassembly 35 to a position opposite the magnetic element 37 of the second subassembly 35 together, and vice versa.

Thus, the cooperation of the first subassembly 34, connected to the screen 2, with the second subassembly 35, connected to the shutter 29 of the air inlet member 25, by means of the magnetic elements 36, 37, so as to open or close the shutter 29, simplifies the control of the second subassembly 35 by the first subassembly 34.

The control device 33 of the ventilation device 24 thus makes it possible to modify the position of the shutter 29 of the air inlet member 25 by means of the motorized drive device 5 causing the displacement of the screen 2 and, more particularly, to move the shutter 29 between an open position and a closed position.

In this way, the screen 2 of the concealment device 3 is configured to move in front of the air inlet member 25, in particular in a vertical movement, at a minimum horizontal distance d, as well as in front of the window 30, so as to be able to control the second subassembly 35 by the first subassembly 34, by means of the magnetic elements 36, 37.

The position opposite the magnetic elements 36, 37 is a position where these magnetic elements are aligned vertically, with a possible tolerance in height, for example of plus or minus half the horizontal distance d, preferably more or less than one fourth of the horizontal distance d. A position shifted from the magnetic element 36 with respect to the magnetic element 37 is a position where the difference in height between these magnetic elements is, for example, greater than the horizontal distance d. The offset considered is a vertical offset.

Advantageously, the air inlet member 25 comprises a return element 39 of the shutter 29 in the open position, when the magnetic element 36 of the first subassembly 34 is in a shifted position, in the direction of displacement of the screen 2, with respect to the magnetic element 37 of the second subassembly 35.

Thus, the shutter 29 of the air inlet member 25 is moved to the open position by means of the return element 39, as soon as the magnetic element 36 of the first subassembly 34 is in a position shifted, in the direction of movement of the screen 2, relative to the magnetic element 37 of the second subassembly 35.

In this way, the rest position corresponding to the open position of the shutter 29 of the air inlet member 25 is guaranteed by the return element 39.

In one embodiment, the biasing element 39 is a spring, for example blade or spiral.

Here, the return element 39 is arranged around the axis of rotation Y of the shutter 29.

In another embodiment, not shown, the biasing element 39 is a counterweight. The counterweight can be either integrated in the shutter 29 or attached to the shutter 29.

Advantageously, the magnetic element 36 of the first subassembly 34 and the magnetic element 37 of the second subassembly 35 are configured to generate a closing force of the shutter 29 of the air inlet member 25. , against the force exerted by the biasing element 39, when the magnetic element 36 of the first subassembly 34 is positioned opposite the magnetic element 37 of the second subassembly 35. .

Thus, during the positioning of the magnetic element 36 of the first subassembly 34, connected to the screen 2, vis-à-vis the magnetic element 37 of the second subassembly 35, connected to the shutter 29, the magnetic element 36 of the first subassembly 34 and the magnetic element 37 of the second subassembly 35 repel each other, so as to modify the position of the shutter 29 and, in particular, to move the shutter 29. shutter 29 from an open position to a closed position.

This arrangement in opposition to the magnetic element 36 of the first subassembly 34 with respect to the magnetic element 37 of the second subassembly 35 is preferred, so as to generate a repulsive force, compared to the assembly where a force of attraction is generated by the approximation of the magnetic element 36 of the first subassembly 34 relative to the magnetic element 37 of the second subassembly 35. This last assembly would have the effect of creating an acceleration during the displacement of the second subassembly. 35 relative to the first subassembly 34, due to an increase in the force generated by the approach of the magnetic element 36 of the first subassembly 34 with respect to the magnetic element 37 of the second subassembly 35. , which can cause a mechanical shock and therefore noise.

When passing from the open position to the closed position of the shutter 29 of the air inlet member 25, the magnetic element 36 of the first subassembly 34 is positioned opposite the magnetic element 37 of the second subassembly 35, by the activation of the motorized drive device 5 of the concealment device 3, so that the magnetic element 36 of the first subassembly 34 exerts a force on the element magnetic device 37 of the second subassembly 35, in particular of repulsion.

During the transition from the open position to the closed position of the shutter 29 of the air inlet member 25 and in this closed position, the return element 39, in particular the spring, of the shutter of shutter 29 is compressed by the closing force exerted between the magnetic element 36 of the first subassembly 34 and the magnetic element 37 of the second subassembly 35.

When passing from the closed position to the open position of the shutter 29 of the air inlet member 25, the magnetic element 36 of the first subassembly 34 is shifted relative to the magnetic element 37 of the second subassembly 35, by the activation of the motorized drive device 5 of the concealment device 3, so that the magnetic element 36 of the first subassembly 34 stops exerting a force on the magnetic element 37 of the second subassembly 35.

During this transition from the closed position to the open position of the shutter 29 of the air inlet member 25, the return element 39, in particular the spring, of the shutter 29 of the the air inlet member 25 expands to push the magnetic element 36 of the first subassembly 34 relative to the magnetic element 37 of the second subassembly 35.

By way of non-limiting example, the horizontal distance d between the first subassembly 34 and the second subassembly 35 can be in a range extending between five millimeters and forty millimeters, and preferably of the order of fifteen. millimeters, when the magnetic element 36 of the first subassembly 34 is positioned vis-à-vis the magnetic element 37 of the second subassembly 35.

In addition, the use of magnetic elements 36, 37 at the first and second subassemblies 34, 35 of the control device 33 of the ventilation device 24 improves the aesthetics of the home automation system.

Moreover, the use of magnetic elements 36, 37 at the level of the first and second subassemblies 34, 35 of the control device 33 of the ventilation device 24 makes it possible to minimize the costs of obtaining the device 33 for controlling the device 24, and to minimize the size of the control device 33 of the ventilation device 24.

The cooperation of the first subassembly 34 with the second subassembly 35 by means of magnetic elements 36, 37 also makes it possible to avoid transmitting a force via the screen 2 and, in particular, by blades of the screen 2 against each other and in a vertical direction, in the assembled configuration of the home automation system.

The only force that can be exerted on the screen 2 is a horizontal force due to the magnetic elements 36, 37 of the first and second subassemblies 34, 35, when the magnetic element 36 of the first subassembly 34 is positioned under with respect to the magnetic element 37 of the second subassembly 35.

In this way, this horizontal force due to the magnetic elements 36, 37 is not likely to generate malfunctions during the winding or unwinding of the screen 2.

The cooperation of the first subassembly 34 with the second subassembly 35 by means of the magnetic elements 36, 37 makes it possible, in addition, to provide a device 33 for controlling the ventilation device 24 without mechanical friction between the first subassembly 34 and the second subset 35.

The control of the position of the shutter 29 of the air inlet member 25 regulates the flow of air flow F between the outside and the inside of the building. Positioning the shutter shutter 29 in the closed position limits thermal losses during a heating period of the building interior. In addition, the positioning of the shutter 29 in the open position allows to circulate the air flow F between the outside and inside of the building, so as to improve the quality of the air inside. of the building.

Preferably, the first subset 34 connected to the screen 2 comprises at least one first magnetic element 36 disposed at the lower part of the screen 2 and at least one second magnetic element 36 disposed at the upper part of the screen. the screen 2, so as to change the position of the shutter 29 of the air inlet member 25, when the screen 2 is respectively in or near the upper position and in or near the the low position.

Thus, the control device 33 of the ventilation device 24 can make it possible to control the second subassembly 35 connected to the shutter shutter 29 by the first subassembly 34 connected to the screen 2 in the raised position and in the position bottom of the screen 2.

The control device 33 of the ventilation device 24 can also make it possible to control the second subassembly 35 by the first subassembly 34 in several positions of the screen 2.

In this way, the modification of the position of the shutter 29, on the one hand, in the upper position of the screen 2 and, on the other hand, in the lower position of the screen 2, requires that the first sub -assemble 34 comprises a first magnetic element 36 and a second magnetic element 36 and that the second subassembly 35 comprises another magnetic element 37.

In addition, the positioning of the first magnetic element 36 of the first subassembly 34 at the lower part of the screen 2 makes it possible to modify the position of the shutter 29, when the screen 2 is in the high position, so that you can generate an air flow through the air inlet member 25, especially the day.

And the positioning of the second magnetic element 36 of the first subassembly 34 at the upper part of the screen 2 makes it possible to modify the position of the shutter 29 when the screen 2 is in the low position, so that to be able to generate a flow of air through the air inlet member 25, particularly at night.

Advantageously, the first magnetic element 36 of the first subassembly 34 connected to the screen 2 is disposed at the level of the final end blade 8 of the screen 2, as visible in FIG. figure 6 . In addition, the second magnetic element 36 of the first subassembly 34 connected to the screen 2 is disposed at one of the upper blades of the screen 2, as visible in FIGS. figures 4 and 5 .

In a preferred embodiment, the magnetic element 37 of the second subassembly 35 is disposed at the outer face of the air inlet member 25 and, more particularly, on the outside of the window 30, so as to minimize the horizontal distance d between the first subassembly 34 and the second subassembly 35, when the magnetic element 36 of the first subassembly 34 is positioned vis-à-vis the magnetic element 37 of the second subassembly 35.

Advantageously, the smaller the horizontal distance d between the first subassembly 34 and the second subassembly 35, when the magnetic element 36 of the first subassembly 34 is positioned vis-à-vis the magnetic element 37 the second subassembly 35, plus the displacement of the first subassembly 34, connected to the screen 2, relative to the second subassembly 35, connected to the shutter 29 of the air inlet member 25, necessary for the passage of the shutter 29 from its open position to its closed position, is low.

Thus, the modification of the position of the shutter 29 of the air inlet member 25 can be implemented by a small amplitude of the movement of the screen 2, so as to discrete this movement of the screen 2.

Preferably, the position modification of the shutter 29 of the air inlet member 25 is implemented by a displacement of the screen 2 from a first position, where the magnetic element 36 of the first subassembly 34 is in a shifted position, in the direction of movement of the screen 2, in particular vertical, with respect to the magnetic element 37 of the second subassembly 35, towards a second position, where the element The first subassembly 34 of the magnetic circuit 36 is positioned opposite the magnetic element 37 of the second subassembly 35, and vice versa.

Thus, the modification of the position of the shutter 29 of the air inlet member 25 is implemented by a displacement of the screen 2 generated by the motorized drive device 5 of the concealment device 3 .

In this way, the position modification of the shutter shutter 29 can be implemented by a small amplitude movement of the screen 2, so that the user does not notice this operation.

By way of non-limiting example, the displacement distance of the screen 2 allowing the position of the shutter 29 of the air inlet member 25 to be modified can be of the order of 1% or 2 % of the movement of displacement of the screen 2 between the low position and the high position.

In one embodiment, the displacement of the screen 2 allowing the position of the shutter 29 of the air inlet member 25 to be modified is implemented by means of the electromechanical actuator 11 driving the screen 2 at a reduced speed compared to a nominal speed of displacement of the screen 2, so as to minimize the noise induced by this maneuver.

Thus, by moving the screen 2 at reduced speed by means of the electromechanical actuator 11, the air inlet member 25 can be controlled in all or nothing, so as to regulate the flow of air F through this air inlet member 25 and, in particular, the flow of air between the outside and the inside of the building.

In such a case, the electric motor 16 of the electromechanical actuator 11 may be of DC brushless DC type.

Advantageously, the shutter 29 is placed in its closed position, when the screen 2 is in the position where the magnetic element 36 of the first subassembly 34 is positioned vis-à-vis the magnetic element 37 of the second subassembly 35. If there is a need for a flow of air through the air inlet member 25, a displacement of the screen 2 is generated by the motor drive device 5 of the occultation device 3, so as to switch the shutter 29 in the open position. The open position of the shutter 29 is obtained when the magnetic element 36 of the first subassembly 34 is in a shifted position, in the direction of movement of the screen 2, relative to the magnetic element 37 of the second subset 35.

In one embodiment, the first position where the magnetic element 36 of the first subassembly 34 is in a shifted position, in the direction of movement of the screen 2, relative to the magnetic element 37 of the second sub-assembly. together 35 corresponds to a limit position of the screen 2.

And, the second position where the magnetic element 36 of the first subassembly 34 is positioned vis-à-vis the magnetic element 37 of the second subassembly 35 corresponds to a predetermined position, in particular during the implementation. service of the home automation installation, preceding a limit position of the screen 2, according to the direction of movement of the screen 2.

Here, the first position corresponds to the upper limit position of the screen 2, when the screen 2 is in the up position, and to the lower end position of the screen 2, when the screen 2 is in the low position.

And, the second position corresponds to a predetermined high position preceding the upper end position of the screen 2, according to the rising direction of the screen 2, and to a predetermined low position preceding the low end position. of screen 2, according to the direction of descent of screen 2.

Thus, the predetermined high and low positions corresponding to the second position, where the magnetic element 36 of the first subassembly 34 is positioned vis-à-vis the magnetic element 37 of the second subassembly 35, are arranged between the top end position of the screen 2 and the bottom end position of the screen 2.

• la position de fin de course haute de l'écran 2 dans laquelle le volet d'obturation 29 est en position ouverte,
• la position prédéterminée haute précédent la position de fin de course haute de l'écran 2 dans laquelle le volet d'obturation 29 est en position fermée,
• la position de fin de course basse de l'écran 2 dans laquelle le volet d'obturation 29 est en position ouverte, et
• la position prédéterminée basse précédent la position de fin de course basse de l'écran 2 dans laquelle le volet d'obturation 29 est en position fermée.

In such a case, the screen 2 can take at least four positions, namely:

• the upper limit position of the screen 2 in which the shutter 29 is in the open position,
• the predetermined high position preceding the high end position of the screen 2 in which the shutter 29 is in the closed position,
• the low end position of the screen 2 in which the shutter 29 is in the open position, and
• the predetermined low position preceding the low end position of the screen 2 in which the shutter 29 is in the closed position.

In a variant, the position of the screen 2 in which the shutter 29 is in the open position does not correspond exactly to the upper or lower end position, but is situated in the vicinity of this end-of-travel position.

In addition, between the predetermined high position preceding the high end position of the screen 2 and the predetermined low position preceding the low end position of the screen 2, the shutter 29 is in the open position. because, in the example, the shutter 29 is subjected to the action of the return element 39.

Thus, the positioning of the shutter 29 in the open position, between the predetermined high position preceding the high end position of the screen 2 and the predetermined low position preceding the low end position of the screen 2, ensures ventilation of the building, when the screen 2 is used as sunscreen, including the summer.

The first position where the magnetic element 36 of the first subassembly 34 is in a position offset from the magnetic element 37 of the second subassembly 35 may also correspond to a position where the final end blade 8 of the screen 2 is located between the predetermined high position preceding the high end position of the screen 2 and the predetermined low position preceding the low end position of the screen 2.

Furthermore, between the predetermined high position preceding the upper end position of the screen 2 and the predetermined low position preceding the low end position of the screen 2, the distance, in the direction of movement of the screen 2, between the threshold 7 of the opening 1 and the lower edge of the final end blade 8 is sufficient to prevent a hissing or that the air flow F at the input member of air 25 is interrupted or limited by the concealment device 3.

In the case where the screen 2 is in the low position, the electronic control unit 15 of the motorized drive device 5 controls the passage of the second position, where the magnetic element 36 of the first subassembly 34 is positioned. opposite the magnetic element 37 of the second subassembly 35 at a position where the magnetic element 36 of the first subassembly 34 is in a displaced position, in the direction of movement of the screen 2, relative to the magnetic element 37 of the second subassembly 35, by a rising movement of the screen 2, so as to allow the flow of the air flow F between the threshold 7 of the opening 1 and the lower edge of the final end blade 8 and / or through the openings between the blades of the screen 2.

In another case, the sensor detects the presence of the magnetic element 36 of the first subassembly 34 and transmits a signal to the electronic control unit 15 of the motorized drive device 5, so as to memorize the position.

In such a case, the sensor is fixed on the air inlet member 25, on the window 30 supporting the air inlet member or on the wall of the building supporting the inlet member of air.

In such a case, a visual indication element 38 makes it possible to determine the position of the shutter 29 of the air inlet member 25, so as to facilitate the manual learning of the first and second positions.

Thus, the visual indication element 38 of the air intake member 25 allows the user to view the position of the shutter 29.

Here, the shutter 29 drives the visual indication element 38, so as to change the position of the visual indication element 38 according to the position of the shutter 29.

Advantageously, the visual indication element 38 of the air inlet member 25 is visible from the inner side of the window 30 and, more particularly, from the interior of the building.

In one embodiment, the visual indication member 38 of the air inlet member 25 is a tab. The tongue is integrally connected to the shutter 29.

In the closed position of the shutter 29, the tongue is in the extended position, so that the latter passes through an opening in the air inlet member 25.

Thus, a portion of the tongue protrudes from an outer wall of the air inlet member 25 so as to be visible outside the air inlet member 25, particularly from the side inside the window 30.

In the open position of the shutter 29, the tongue is in the retracted position, so that it is brought back inside the air inlet member 25.

Thus, the tongue does not exceed the outer wall of the air inlet member 25, so as to be masked.

Advantageously, the visual indication element 38 of the air inlet member 25 may be colored, for example, red, so as to facilitate the visualization thereof.

In the embodiment shown in Figures 4 to 6 , the magnetic element 36 of the first subassembly 34 connected to the screen 2 is disposed inside one of the blades of the screen 2.

Thus, the magnetic element 36 of the first subassembly 34 is integrated in one of the blades of the screen 2, so as to be masked.

In another embodiment, the magnetic element 36 of the first subassembly 34 connected to the screen 2 is disposed on at least one face, external and / or internal, of one of the blades of the screen 2.

Preferably, the face of the blade of the screen 2 on which is disposed the magnetic element 36 of the first subassembly 34 faces the outer side of the window 30, in the assembled configuration of the home automation system.

Thus, the magnetic element 36 of the first subassembly 34 can be fixed on one of the blades of the screen 2, following the commissioning of the home automation system and, in particular, on a concealment device 3 existing during an improvement of the home automation system of adding a control of the air inlet member 25 according to the displacement of the screen 2 of the occulting device 3.

Here, the magnetic element 36 of the first subassembly 34 is fixed on one of the blades of the screen 2 by gluing, in particular by means of an adhesive.

In this way, the electronic control unit 15 of the motorized drive device 5 can allow the passage of the open position to the closed position of the shutter 29, and vice versa, in a duty cycle, which can be variable.

Advantageously, the electronic control unit 15 of the motorized drive device 5 controls the positioning of the shutter shutter 29 of the air inlet member 25 in all or nothing, according to a modulation signal of width impulse. The pulse width modulation signal is emitted by the electronic control unit 15 of the motorized drive device 5, and in particular by the microcontroller thereof.

The sensor 40 measuring at least one parameter of the air passing through the air inlet member 25 may be disposed inside the air flow duct 26, or near the air inlet opening 27 or the air outlet opening 28 formed respectively at one of the two ends of the air duct 26.

Thus, the sensor 40 of the air inlet member 25 can be used to regulate the flow of air F flowing from the outside of the building to the interior of the building.

In the case where the humidity is lower than a first threshold value, for example of the order of 40%, the shutter 29 is maintained in the closed position.

In the case where the humidity is greater than a second threshold value, for example of the order of 60%, the shutter 29 is kept in the open position.

In the case where the humidity is between the first threshold value and the second threshold value, the shutter 29 is switched between the closed position and the open position according to modulation cycles, in particular of long duration, such that for example of the order of ten minutes.
