Description

ENCASTRABLE ELECTRICAL BOX AND ADAPTABLE CONTROL INTERFACE ON THIS HOUSING

Technical area

The present invention relates to the remote control of electrical appliances, particularly in the field of home automation. Its main objects are a new electrical box built into a wall such as a wall or a partition, and a control interface, which is adaptable on said housing so as to form an intelligent control device. Each control device may preferably comprise wireless communication means, which make it possible to easily form, by means of several control devices, a wireless communication network, and in particular a mesh network of "mesh" type.

Prior art

In a conventional electrical installation, a mechanical switch or the like for controlling an electrical appliance (light, shutter, heater, air conditioner, etc.) connected to or connected to the general electrical network, is usually fixed to a wall , such as a wall or a partition, through an electrical connection box. An electrical connection box is constituted by a pot, which is generally made of plastic material, and which is easily embedded in a reservation formed in said wall. This pot is in the form of an open receptacle having a bottom extended transversely and over its entire periphery by a side wall, so as to define a housing for the mechanical switch or the like. The shape and dimensions of this type of pot are generally standardized. Most often, but not necessarily, this type of pot is cylindrical. In the bottom of the pot are provided openings for the passage of the electrical son of connection to the general power grid. The connection to the general electrical network of the mechanical switch or equivalent is thus made through the bottom of the pot. When it is desired to install or change a mechanical switch or the like, it is therefore necessary beforehand to connect it electrically to the general electrical network delivering a high power AC signal, for example an AC electrical signal of 220. volts. This connection operation is tedious, generates significant risks of electrocution, and should preferably be performed by qualified personnel, to avoid in particular the risk of short circuit.

In the field of home automation, it has been proposed to date different types of intelligent switches able to communicate wirelessly and remotely between them and / or with a remote control, and for example with a mobile phone, for remote control domestic electrical appliances electrically connected to the electricity grid.

More particularly, it has for example already been proposed to this day to replace, in a domestic electrical installation, a conventional mechanical switch, by a control device, which incorporates triacs type power switching means, which can be easily housed in a conventional electric pot, and remotely remotely controlled, for example by means of a mobile phone in which is stored a suitable software application. This control device integrable into an electrical connection pot can also communicate remotely with other control devices so as to form a wireless communication network. In this solution, the control device which is housed in the pot must be wired electrically connected to the general electrical network delivering a high power alternating current (AC). This connecting operation, tedious and significant source of electrocution risks, must be performed every time you want to install or replace a control device in situ. Other types of intelligent switches, which are able in particular to be substituted for conventional mechanical switches in an existing electrical installation, are described for example in the US patent application US2004 / 0067144 and in the US patent application US 2015 / 02804040.

More particularly, in the aforementioned US patent application 2015/02804040, the intelligent switch, designated "master switch" in this publication, comprises wireless communication means allowing it to form, with other intelligent switches sufficiently close, a mesh-type wireless mesh communication network using Bluetooth Low Energy (BLE) technology. This intelligent switch can also communicate wirelessly in BLE technology with a hub hub, which is able to interpret and convert a WIFI signal to a corresponding BLE signal, so as to allow communication over a greater distance with devices further away through the Internet.

In all cases these smart switches must be wired electrically connected to the general power grid delivering a high power alternating current (AC), and this connection operation, tedious and significant source of electrocution risks, must be carried out each time. that we want to install or replace in situ a smart switch.

US Pat. No. 8,781,639 has furthermore proposed a receptacle that can be fitted into a wall such as a wall or partition, on which at least one socket can be attached and connected for connecting an electrical appliance to the electrical network. ; this built-in receptacle integrates a microprocessor (MCU), communication means for forming a communication network with other receptacles of the same type and electronic means for measuring the local power consumption through the electrical outlet. This receptacle also incorporates an AC / DC converter, which must be electrically connected to the general network. The low power DC signal delivered by the converter is used to supply the microprocessor, the network communication means and the electronic means for measuring the power consumption. In this technical solution, the electrical outlet must necessarily, as for a conventional electrical outlet, be wired electrically connected to the general electrical network delivering a high power alternating current (AC).

detailed description

FIG. 1 shows a control device 1 of the invention comprising an electric box 10 (referenced more particularly 10A in this variant of FIG. 1) and a control interface 11 that is attached and removable relative to the electric box 10.

Electrical box 10A

The electrical box 10A comprises a pot 100A. In this particular example, this pot 100A is embedded in a wall P by being inserted through a front wall CL of said wall, such as for example a partition type plasterboard.

This pot 100A has a bottom wall PF extended transversely over its entire periphery by a side wall PL, which delimits an inner housing with the bottom wall PF. The pot 100A is further provided on the front face of a base S in the form of a thin plate. The base S may be an attached part fixed by any means on the front face of the side wall PL of the pot 100A. The pot 100A is for example plastic, and the base S may for example be metal or plastic.

The geometry and dimensions of this recessed pot 100A are not limiting of the invention. In particular, the geometry of the bottom wall PF and of the lateral wall PL are not limiting of the invention, the lateral wall PL may for example form a cylinder or any prism with a polygonal base, and for example a right prism having a rectangular or square cross section. The geometry and dimensions of the base S are of no importance for the invention, said base can in particular be of any shape, and in particular a polygonal (square, rectangular, ...) or circular shape.

In this particular example, the recessed pot 100A is equipped with spring clips 101 A, which allow to put the pot 100A against the back side of the partition CL, and thus to oppose the withdrawal of the pot once this recessed. Once the pot 100A recessed into the wall P, the base S in the front of the pot bears against the front face of the wall, that is to say in this example against the front face of the partition CL.

According to the invention, the electrical box 10A comprises an AC / DC converter 102 (AC / DC), which makes it possible to transform a high-power AC electric signal into a DC power signal of lower power, and for example an AC signal. 220V in a 5V / 1A DC signal, and power control means 103. AC / DC converter 102 (AC / DC) and power control means 103 are housed within the flush pot 100A.

More particularly, in this variant embodiment, the power control means 103 comprise an electronic processing unit 103a, of the microprocessor or microcontroller type, and an assembly of several power switches 103b, which are electrically connected to the processing unit. 103a for their control by the electronic processing unit 103a. These power switches 103b comprise, for example, triacs or insulated gate bipolar transistors (IGBTs). The electronic processing unit 103a makes it possible to control these power switches 103b electrically so as to form, for example, a set of several voltage inverters, each of which can deliver a continuous control voltage (for example between OV and 200V). In the following description and in the accompanying figures, the number of voltage variators is four, however, it is specified that this number of voltage variators is not limiting of the invention.

In another variant embodiment, the electronic processing unit 103a can also be implemented in the form of a programmable logic circuit, of the FPGA type or in the form of a specific electronic circuit of the ASIC type.

In the particular embodiment of Figure 1, the electrical box 10A also includes a safety thermostat 104, which controls the temperature inside the pot 100A and automatically cut the electronic processing unit 103a in case of overheating detected.

With reference to FIG. 2, the electrical box 10A has, on the rear face, through the bottom wall PF of the pot 100A, a plurality of fast electrical connection means 105a to 105f, also referred to herein as fast connectors, which are accessible from outside the pot, and which are for example in the form of autoclipsable female plugs.

With reference to FIGS. 1 and 3, the base S comprises a magnetic frame CA, which in this particular embodiment makes it possible to fix the control interface 11A on the front of the pot by magnetization easily, quickly and removably. built-in 100A. In the front face, the electrical box 10A also comprises several fast electrical connection means 106a to 106e, which are accessible from the outside of the pot, and which are for example in the form of dry electrical contacts of the female type. In the particular variant of FIG. 3, there are five dry contacts 106a to 106e, it being specified that this particular number of dry contacts is not limiting of the invention.

Electrical diagram of the electrical box 10A

FIG. 4 shows the electrical connection diagram of the electrical box 10A.

The fast electrical connection means 105a and 105b are electrically connected in the insertable pot 100A to the input of the converter (AC / DC) 102. In addition, the quick connect means 105a is also electrically connected in the insert to each switch of power 103b.

During the installation of the electrical box 10A, these fast electrical connection means 105a and 105b are respectively connected to the phase (PH) and to the neutral (N) of the general high-voltage electrical network. The converter (AC / DC) 102 thus has the function of transforming the high power alternating electrical signal delivered by the general electrical network (for example 220V AC electrical signal) into a lower power continuous electric signal 102a, and in particular into a low power DC signal, for example a 5V / 1A DC power signal. Once the electrical box 10A connected to the general power grid, the phase (PH) of the high power electrical signal of the general power grid is thus connected to each power switch 103b.

In another variant (unipolar), only the phase (PH) can be connected to the electrical box by means of the quick connector 105a, the fast connector 105b not being used or not being present.

The power supply port of the electronic processing unit 103a (microprocessor or microcontroller) and the fast electrical connection means 106a and 106b (on the front face of the pot 100A) are electrically connected to the output of the converter (AC / DC). The low power continuous supply signal 102a delivered by the converter 102 thus supplies the electronic processing unit 103a (microprocessor or microcontroller) and is available on the fast electrical connection means 106a (Vcc) and 106b (GND) on the front of the electrical box. The electronic processing unit 103a is electrically connected to each power switch 103b, and makes it possible to control each power switch electrically and individually by modulating the high power signal (PH) delivered by the general electrical network, so that each power switch 103b operates as a voltage variator, and is capable of delivering a continuous control signal C1 to C4 (for example in 0V and 220V). These control signals C1 to C4 are available on the rear face of the insertable pot 100A respectively on the fast connection means 105c to 105f.

During the installation of the electrical box 10A, each fast connection means 105c to 105f is electrically connected to the electrical control wire of an electrical appliance connected to the general electrical network, and in particular a domestic electrical appliance, which it is desired to control remote with the control interface 11. In a nonlimiting and non-exhaustive manner of the invention, an electrical device may for example be a lighting device, a shutter, a heating device, an air conditioning, an alarm, ...

In the particular variant of FIG. 4, the thermostat (TH) 104 is connected to a serial input port (GPIO) of the processing unit 103a so as to allow automatic shutdown of the processing unit 103a in case overheating detected inside u pot 100A.

In the particular variant of FIG. 4, the processing unit 103 a further comprises, for the exchange of data in master / slave mode with a control interface 11, a serial communication port (MOSI / MISO - clock CLCK). which is respectively connected to the fast connection means 106c, 106d and 106e.

Control Interface 11

FIGS. 5 to 7 show a first embodiment 11A of a control interface 11, in the form of a thin casing 110 incorporating, in the front face, a touch screen 111 constituted for example by a slab capacitive.

In this particular embodiment, the control interface 11A also comprises, on the front face of the housing 110: a brightness sensor 112, a camera 113 of the "webcam" type, a temperature sensor 114, a microphone 115, a directional transmitter infrared type 116 and a speaker 117.

In this particular embodiment, and in a nonlimiting manner of the invention, the housing 110 has on the rear face (FIG. 7) a recess 110a into which the base S of an electrical box 10 can be fitted when the control interface 11 is adapted to an electrical box. In addition, the housing 110 comprises on the rear face a magnetic frame 110b which makes it possible to removably, easily and quickly connect the control interface 11 to the base S of the electrical box 10.

With reference to FIGS. 6 and 7, the control interface 11A comprises, on the rear face, fast electrical connection means 119a to 119e, for example in the form of dry electrical contacts of the male type, which are adapted to cooperate respectively with the means fast electrical connection 106a to 106e of the housing 10A, to provide an electrical connection, low current type, between the housing 10A and the control interface 11A, when the control interface 11A is adapted to the front of the electrical box 10A.

FIG. 8 shows an example (not limited to the invention) of functional architecture of a control interface 11A.

In this particular example, the control interface HAcomporte mainly an electronic processing unit 118 implemented for example in the form of a microprocessor, and four functional modules whose components are connected to the electronic processing unit 118: - a module HMI (Human Machine Interface) comprising the touch screen 111 which allows a user to enter commands manually, the infra-red transmitter 116 and the camera 113; a sensor module comprising the brightness sensor 112 and the temperature sensor 114, an audio module comprising the microphone 115 and the loudspeaker 117, a connectivity module comprising various electronic wireless communication components, which make it possible to remotely and wirelessly communicate the electronic processing unit 118.

In another variant embodiment, the electronic processing unit 118 can also be implemented in the form of a microcontroller, or in the form of a programmable logic circuit, of the FPGA type, or in the form of an electronic circuit Specific ASIC type.

A serial communication port of the electronic processing unit 118 is electrically connected to the fast connection means 119c, 119d, 119e on the rear face of the housing 110. In addition, the electronic processing unit 118 is connected for its power supply to the means quick connection 119a and 119b on the back of the housing 110. It is the same for all the electronic components of the various modules referred to above that require a power supply. The processing unit 118 is configured to execute a specific program stored in memory and enabling it to communicate with its various peripherals (screen 111, sensors 112, 113, microphone 115, IR emitter 116, loudspeaker 117, components of the module. connectivity) and to communicate with the processing unit 103a of an electrical box 10A via the fast connectors 119c / 106c (MOSI), 119d / 106d (MISO), 119e / 106e (CLCLK) for the control by the control unit. 103a of power switches 103b.

Advantageously according to the invention, once an electrical box 10 has been installed in a wall and has been electrically connected as previously described by means of its fast connection means 105a to 105f on the rear face of the housing 100 , the adaptation of a control interface 11 or the replacement of a control interface 11 by another control interface can advantageously be performed very easily and very quickly by positioning the control interface 11 on the front base S of the electrical box and by fitting the male dry contacts 119a to 119e of the control interface 11 in the female dry contacts 106a to 106e of the electrical box 10. This operation is moreover without any risk of electrocution for the user, because only low power electrical signals pass through the fast connectors 106a to 106e on the front of the electrical box 10.

Once fitted to the electrical box 10, the control interface 11 is advantageously "plug and play" and ready to operate without further intervention or parameterization.

In another variant, the dry contacts 119a to 119e of the control interface 11 could be of the female type and the dry contacts 106a to 106e of the electrical box 10 could be of the male type.

Wireless communication

In the particular variant embodiment of FIG. 8, the connectivity module of the control interface 11A mainly comprises: an infrared transmitter 120 which enables the processing unit 118 to send infrared commands locally to a close device

a first wireless module 121 dedicated to a wireless communication on a mesh network (mesh network type) and a second wireless module dedicated to a wireless communication on a WLAN type network, a 123 wifi antenna, a communication module wireless 124 type BLE ("Bluetooth Low Energy") associated with a Bluetooth antenna 125.

In both cases (WIFI and BLE), the communication protocol used is irrelevant and any known communication protocol can be used.

The BLE communication (module 124 and Bluetooth antenna 125) is used for example to communicate with each other in master / slave mode two processing units 118 of two control interfaces 11 respectively adapted to electrical boxes 10 close, and for example positioned in the same room of a building.

The first means of WIFI communication (module 121) makes it possible to easily constitute a meshed communication network (mesh network) with other control interfaces 11 and thus to easily communicate with each other these control interfaces 11 over a greater distance than BLE technology, and for example from one room to another or from one floor to another. These wireless communication means 121 make it possible in particular with a given control interface 11: to remotely control an electrical apparatus which is not directly electrically connected to the electrical box 10 on which the control interface 11 is adapted, but which would be connected to another electrical box 10 on which is adapted another control interface 11, - to recover data sent by the peripherals (camera, temperature sensor, microphone, ...) of another control interface.

The second wireless module 122 dedicated to wireless communication over a WLAN network may for example be used to communicate the unit 118 of a control interface 11 with the Internet network via a router. Other variant embodiments (nonlimiting and non-exhaustive examples of the invention)

FIGS. 9 to 11 show another variant of embodiment 10B of an electrical box 10, which differs mainly from that 10A of FIGS. 1 to 3 in that the base S can be fixed on the recessed pot 100B by means of screws V. In this variant, the built-in pot 100B also has fixing holes T (FIGS. 10 and 11) for fixing it, for example by means of screws, in a wall. The invention is not limited to the control interface 11A previously described. FIGS. 12 to 14 show another variant 11B of control interface 11, which is in the form of a touch screen comprising four touch zones ZT for the manual entry of control by a user.

In this simpler variant, the control interface 11B is devoid of a brightness sensor, a camera, a temperature sensor, a microphone, an IR emitter, and a loudspeaker. Furthermore, in this variant, the wireless communication can for example be provided only by a BLE module allowing this control interface to communicate with a control interface 11 (11A or 11B) close.

In another alternative embodiment (not shown), the electrical box 10 may not include a processing unit 103a in the pot 100A or 100B. In this case, the processing unit 118 of a control interface 11, once the control interface 11 is adapted to an electrical box 10, is electrically connected to the power switches 103b and directly controls these power switches 103b.

In another variant embodiment, all or part of the wireless communication means (121 to 125) can dissociate from the control interface and be housed inside the electrical box 10. In this case the fast connectors between the control interface 11 and the electrical box 10 will be adapted so that the processing unit 118 of the control interface is connected to said wireless communication means inside the housing once the control interface 11 adapted to the housing 10.

In another alternative embodiment, the control of the power control means 103 by the processing unit 118 of a control interface 11 could be achieved by means of a wireless communication between the processing unit 118 and the power control means 103.

In another variant embodiment, the converter 102 may be an AC / AC converter which makes it possible to transform the high power AC electric signal into a lower power electrical AC signal 102a, and in particular into an electrical signal. alternative low power 102a. In this case, rectifying means of the AC electrical signal 102a in a continuous signal can be implemented outside the electrical box, and for example rectifying means of the AC electrical signal 102a can be integrated in the control interface. The invention is not limited to the implementation of an electrical box 10A or 10B having a 100A or 100B pot recessed directly into a wall. In another variant embodiment, such as that illustrated for example in FIG. 15, the flush-mounted pot 100C of the electrical box 10C can also be adapted to fit or fit into an existing standard electrical connection pot 2, already previously recessed and fixed in a wall.
