[0021] According to an advantageous characteristic of the invention, the front wall of the deflector has a truncated cone shape.

[0022] According to an advantageous characteristic of the invention, the deflector comprises a removable cover closing the central opening.

[0023] Such a feature makes it possible to block any airflow emitted by the fan directly towards the user. Such a feature also makes it possible to maximize the surface area used to diffuse and / or reflect light.

[0024] According to an advantageous characteristic of the invention, the fixing means com- take clipping elements or magnetic means.

[0025] The invention also relates to a fan comprising an electric motor, a propeller driven in rotation by said motor and a protective grille arranged around said propeller, characterized in that it comprises a lighting kit as previously described. Brief description of the figures

[0026] The aims, aspects and advantages of the present invention will be better understood from the description given below of a particular embodiment of the invention presented by way of non-limiting example, with reference to the appended drawings in which:

[0027] [Fig.l] is a front view of a fan equipped with a lighting device according to a particular embodiment of the invention, the lighting device being illustrated in a configuration without a central cover;

[0028] [Fig.2] is a perspective view of the fan head without the lighting device of [Fig.l] in a configuration with the central cover;

[0031] [Fig.5] is a sectional view of the fan head equipped with the lighting device in a configuration without a central cover;

[0032] [Fig.6] is a perspective view of the fan head equipped with the lighting device of [Fig.l] in a configuration with the central cover;

[0033] [Fig.7] is a perspective view of different types of deflectors and different types of covers that can be fitted to the lighting device.

[0034] Only the elements necessary for understanding the invention have been shown. To facilitate reading of the drawings, the same elements bear the same references from one figure to another.

[0035] It will be noted that in this document, the terms "horizontal", "vertical", "lower", "upper", "top", "bottom", "front", "rear", "longitudinal", "transverse", used to describe the fan refer to this device in use, when it rests flat on its foot with the axis of the fan propeller arranged horizontally.

[0036] [Fig.l] illustrates a domestic appliance, of the pedestal fan type 1, comprising a foot 1 intended to rest on a flat surface, such as the floor or a table, and a fan head 2 carried by said foot 1.

[0037] According to figures 2 to 5, the fan head 2 comprises a propeller 3 surrounded by a protective grid 6, the propeller 3 being driven in rotation by a motor 4 arranged in a housing 5 which is pivotally mounted on the foot 1 by means of an articulation 50, the housing 5 having a front longitudinal end which is crossed by an output shaft of the motor 4 at the end of which the propeller 3 is fixed. Advantageously, the fan is provided with heating means, not shown in the figures, constituted for example by a heating resistor swept by the air flow produced by the propeller 3, allowing it to be used to heat a room.

[0038] The protective grid 6 comprises a rear grid 60, a front grid 61 and an annular fixing flange 7 which ensure the holding of the front 61 and rear 60 grids on one another. The rear grid 60 and the front grid 61 define a cage in which the propeller 3 is arranged, the rear grid 60 being fixed to the front longitudinal end of the housing 5 and comprising a central part extending behind the propeller 3 and a peripheral part which extends to the periphery of the propeller 3. The peripheral part of the rear grid 60 has a front end defining a circular opening which is closed by the front grid 61, the latter being fixed to the rear grid 60 by means of the annular fixing flange 7. The front grid 61 advantageously has a curved surface and comprises, in its center, a flange 62 coming opposite the hub of the propeller 3 to mask the latter.

[0039] The fixing flange 7 is advantageously made of metal, or of plastic, and locally comprises a cutout 70 at a location on its periphery allowing the fixing flange 7 to deform, with a view to its removal from the rear grille 60, when the user manually pulls on either side of the cutout 70. The fixing flange 7 advantageously comprises, on either side of this cutout 70, fixing studs 71, 72 between which is mounted a spring, not shown in the figures, which tends to bring the two edges of the fixing flange 7 together.

[0040] According to Figures 3 to 5, the apparatus comprises a lighting device 8 mounted on the fan protection grille 6, the lighting device 8 advantageously being in the form of a removable lighting kit 8 comprising a ring-shaped light frame 80 which supports at least one light source 81. Preferably, the light source 81 is supplied with electricity by means of a power supply cable 82 which opens onto one side of the light frame 80 and the free end of which is provided with a socket 83 intended to engage with an electrical power supply connector 20 carried by the fan head 2.The power supply connector 20 is advantageously arranged in the vicinity of the protective grid 6 and is connected to a low-voltage transformer which is integrated into the housing 5 of the fan and whose power supply is independent of that of the motor 4, the transformer being connected to the electrical network of the fan and supplying the connector 20. with a direct current of 12V voltage.

[0041] The light frame 80 is removably fixed on the periphery of the fixing flange 7 and advantageously has a diameter of between 40 cm and 60 cm. The light frame 80 can for example be held on the fixing flange by magnetic attraction, by clipping or by friction. Thus, the light frame 80 can comprise magnets which cooperate with metal parts of the fixing flange 7 to ensure the magnetic holding of the light frame 80 on the fixing flange 7. In an alternative embodiment, the light frame 80 can be provided with several fixing clips intended to engage elastically on the fixing flange 7 to ensure the holding of the light frame 80 on the fixing flange 7.

[0042] The lighting device 8 advantageously comprises a deflector 84 which is removably mounted on the light frame 80 and which has the function of diffusing and / or reflecting the light emitted by the light frame 80. The deflector 84 comprises a front wall 84A which extends in front of the front grille 61, advantageously matching the curvature of the latter, the front wall 84A having a central opening 84C which is centered relative to the axis of rotation of the propeller 3 and whose diameter is slightly less than the diameter of the propeller 3.

[0043] Preferably, the front wall 84A of the deflector 84 extends radially, from the outer edge of the front grille 61, over less than 30% of the radius of the front grille 61 so that the central opening 84C has a radius representing at least 70% of the radius of the protective grille 6.

[0044] The front wall 84A of the deflector 84 is placed in front of the light frame 80 and is extended at its periphery by a collar 84B which engages around the light frame 80. The collar 84B is advantageously provided with fixing clips, not visible in the figures, intended to engage elastically on the light frame 80 to ensure the deflector 84 is held on the light frame 80. In an alternative embodiment, the collar 84B may comprise metal inserts which cooperate with magnets carried by the light frame 80 in order to ensure magnetic retention of the deflector 84 on the light frame 80.

[0045] The light source 81 is advantageously arranged on the light frame 80 such that the light rays coming from the light source 81 are emitted by the front face of the light frame 80 and illuminate the front wall 84A of the deflector 84.

[0046] By way of example, the light source 81 comprises at least one LED which is powered with a voltage of 12V by the power cord. Preferably, the light source 81 comprises several LEDs regularly distributed around the entire periphery of the light frame 80 and arranged in a groove provided on the front face of the light frame 80.

[0047] The front wall 84A of the deflector 84 is preferably made of a translucent material which diffuses the light emitted by the light source 81. In an alternative embodiment, illustrated in [Fig.7], the deflector 84 may also have openings 84D for the passage of light and be made, for example, of an opaque material.

[0048] For example, the front wall 84A of the deflector 84 may be made of a translucent white plastic material and the LEDs emit colored light. Preferably, the LEDs are controlled by an electronic card, advantageously embedded in the light frame 80, which is controlled by a remote control, or using a dedicated application on a smartphone, allowing the user to choose the lighting color from several possible colors and to vary the intensity of the lighting.

[0049] In an alternative embodiment of the invention, the lighting device 8 comprises several deflectors 84, of different shapes and / or colors which can be removably mounted on the light frame 80. In this way, the user can choose the deflector 84 of the shape and / or color that he wishes to have the desired lighting effect.

[0050] Preferably, the lighting device 8 also comprises a cover 85 or several covers 85 intended to close the central opening 84C formed in the center of the deflector 84. As illustrated in FIGS. 3, 4 and 6, the cover 85 advantageously has the shape of a curved disc having a curvature matching the shape of the front grille 61. The cover 85 is preferably held in position on the protective grille 6 by being sandwiched between the light ring and the deflector 84. In an alternative embodiment, the cover 85 may be fixed to the deflector 84 by fixing clips or by magnetic attraction.

[0051] As illustrated in [Fig.7], the cover(s) 85 may also have openings 85A forming decorative patterns and allowing a slight passage of air flow. Thus, the cover 85 may include circular openings 85A of different sizes, preferably with a diameter less than 10 cm, and / or slots in the shape of an arc of circles or of various geometric shapes.

[0052] The fan as described above can of course be used without the lighting device 8, like a conventional fan, in order to produce a flow of air, cold or hot, towards the user, but it especially has the advantage of being able to be used in association with the lighting device 8, making it possible to transform the fan into a lighting system capable of providing ambient light of different colors and different intensities depending on the user's choice.

[0053] To do this, the user simply mounts the light ring on the flange of fixing 7 of the protective grid 6, to plug the power cord into the connector 20 of the fan housing 5, then to put in place one of the deflectors supplied with the lighting device 8, as illustrated in figures 1 and 5. The choice of the deflector 84 is made by the user according to its color and its patterns in order to obtain the desired decorative effect.

[0054] The light ring is switched on by the user using the remote control, the latter also allowing the color and intensity of the light emitted by the light ring to be selected.

[0055] The lighting device 8 can also be used in a configuration with the cover 85, as illustrated in [Fig. 6], such a configuration making it possible to maximize the light diffusion of the lighting device 8, in particular when the cover 85 is made of a translucent material. In this configuration of use, the motor 4 of the fan can be stopped, to benefit only from the light produced by the device, or with the motor 4 running in order to generate a flow of air distributed in a diffuse manner, by ricochet on the cover 85, in the direction of the rear and the periphery of the fan. Such use of the fan with the cover 85 is particularly advantageous when the fan is used with the heating function, in order to heat a room, because it avoids an overly directional flow of hot air which could be unpleasant for the user.

[0056] The ventilation device thus produced therefore has the advantage of offering both a ventilation function and a lighting function, which makes it possible to considerably increase the use of such a device, particularly outside of summer periods.

[0057] Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only as an example. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

[0058] Thus, in an alternative embodiment not shown, the light frame may be without a power cable and may have a battery providing the electrical power supply to the light sources.

[0059] Thus, in an alternative embodiment not shown, the deflector may be in one piece with the cover and extend over the entire surface of the front grille.
