Description

Technical area

The present invention relates to a refrigerated beauty box, for the storage and use of cosmetic products.

We know that to have optimal conservation and maximum effectiveness, cosmetic products must be stored at a temperature of around 10°C, i.e. in practice a temperature of between 6°C and 14°C.

To facilitate the beauty routine of users as well as for their comfort, it is preferable that their cosmetic products be placed in the care area, i.e. in the bathroom, bedroom, etc.

In either case, it is desirable for the box to be efficient, compact and not very noisy.

BACKGROUND OF THE INVENTION

It is known from the document WO 2006010539 to produce a refrigerator having an insulating wall comprising an opening equipped with a Peltier module having a cold face associated with a cold radiator opening towards the interior of the refrigerator and a hot face associated with a hot radiator opening towards the outside of the refrigerator .

No provision is made for the refrigerator to be compact and low noise. US 4,007,600A discloses a thermoelectric refrigerator with a configuration of two thermostats which are independently controlled by separate control units.

OBJECT OF THE INVENTION

A first object of the invention is to provide a refrigerated beauty box configured to provide sufficient air flow to ensure satisfactory temperature regulation while remaining compact and silent.

BRIEF DESCRIPTION OF THE INVENTION

With a view to achieving this object, a refrigerated beauty box as defined in claim 1 is proposed according to the invention. It comprises: an insulating plate comprising an opening equipped with a Peltier module having a cold face opening towards the inside the cabinet and a hot face opening outwards from the cabinet; a cold radiator in contact with the cold face; a hot radiator in contact with the hot face; a normal operating temperature sensor associated with a Peltier module power supply control unit; and a hot fan associated with the hot radiator and an oversized outlet manifold with respect to a rated flow rate of the fan.

According to additional characteristics which can be taken individually or in combination, in relation to the first object of the invention: the outlet manifold opens out along a lower rear edge of the box; the hot fan is a axial fan; the cabinet includes a filter associated with the hot fan; the hot fan filter is spaced from the hot fan; the box comprises a cold frame, preferably a rigid frame, in which the cold radiator is embedded, and a flexible joint is placed along the edge of the cold frame; the box comprises a hot shell surrounding the hot radiator, and a rear frame resting on a flexible joint arranged along the edge of the hot shell.

Furthermore, it is known that the temperature inside a refrigerated enclosure is regulated by a thermostat which controls the cold production equipment.

In this regard, according to an observation which is already part of the invention, it has been found that in the case of use of a Peltier module in a refrigerated enclosure of small dimensions there is a risk of exceeding the temperature limits. which can lead to denaturation of the products either by too low a temperature inside the refrigerated enclosure, or by excessive heating of the components which must ensure evacuation of the heat produced by the cold production components.

A second object of the invention is to provide a refrigerated beauty box making it possible to store cosmetic products in an optimal manner and to boost their effectiveness while being configured to deal with problems of heating or cooling.

With a view to achieving this second object, a box is proposed according to the invention comprising at least one safety temperature sensor associated with the control unit which is configured to cut off the supply to the Peltier module when said at least a safety temperature sensor reaches a critical temperature.

Preferably, said at least one safety temperature sensor is carried by the corresponding radiator.

By cosmetic product is meant according to the present invention any substance or any mixture intended to be brought into contact with the superficial parts of the human body (epidermis, hair and capillary systems, nails, lips and external genital organs) or with the teeth and the oral mucous membranes with a view, exclusively or mainly, to cleaning them, perfuming them, modifying their appearance, protecting them, keeping them in good condition or correcting body odours. Thus, a cosmetic product according to the present invention also comprises dermo-cosmetic or dermatological products.

Thus, in a particularly preferred manner, these cosmetic products are chosen from:

• perfumes: very sensitive to environmental changes, it is important to keep them in a cool place away from light to preserve the intensity of the perfumed notes.
• nail polishes: by keeping them cool, nail polishes remain fluid and supple and are thus easier to apply.
• masks: in order to make the application of masks on the face pleasant and to enjoy a feeling of freshness on application, it is recommended to place them in a cool place beforehand; not to mention the beneficial effects of the cold on the complexion, the pores and the toning of the skin.
• lipsticks: by remaining at the bottom of the bag or during periods of high heat, lipsticks soften. Keeping them cool prevents them from breaking. This also helps preserve their shape and consistency.
• creams: keeping them cool makes it possible to optimize the effectiveness and preservation of the formulas and at the same time obtain a beneficial refreshing effect on the complexion, the pores and the toning of the skin. It is therefore recommended to place cosmetic creams in a cool place.
• eye care: to optimize the effectiveness of the formulas and obtain a reduction effect on puffiness and dark circles, it is recommended to place them in a cool place. The decongestant and tightening effects are increased tenfold by the cold.
• lip and eye pencils: to obtain a firm mine and a precise outline, it is necessary to place the lip and eye pencils in a cool place before use.
• micellar waters: micellar waters are known for their make-up removing and cleansing effects. Mainly composed of water, they are all the more pleasant to use after being placed in a cool place. A tensor effect allowing to tighten the dilated pores as well as to reduce the production of sebum is observed.
• mists: thanks to the benefits of the cold, the skin is toned and firmed.
• care for heavy legs: care for heavy legs is even more effective if kept cool. Their soothing and decongestant powers are intensified, thus helping to resolve pain caused by circulation problems.
• floral waters: Floral waters are extremely sensitive to air, light and heat. Cold is essential for their conservation.

Finally, in general, for all "homemade" and/or preservative-free cosmetic products, in particular comprising a large aqueous phase, it is preferable to keep them cool (creams, lotions, gels, etc.) in order to prevent the proliferation of germs and bacteria.

Storage of these cosmetic products in the refrigerated beauty box according to the invention, to optimize their preservation and their effectiveness, is therefore particularly recommended.

Preferably according to the invention, the cosmetic products stored in the box contain water.

Description of embodiments

It will be noted that throughout the application, in most cases, the terms hot and cold do not designate a state of the component concerned but a functionality of the component. For example, the cold face of the Peltier module is the face that will become cold when the Peltier module is powered, etc.

With reference to the figures, the box 1 according to the invention comprises a cold tank delimited by a front wall 2, a rear wall 38, two side walls 4 of which only one is visible in the figures and a bottom 3.

The cold tank is closed in a sealed manner by a cover 5 connected in an articulated manner around a rear upper edge 6 of the box. The walls of the cold tank are insulated with thermal foam (39).

The box comprises a refrigeration device comprising a Peltier module 11 embedded in a window 10 of an insulating plate 9 arranged between a hot radiator 8 and a hot shell 35. The Peltier module 11 comprises a hot face 22 turned towards the exterior of the cabinet, and a cold face 23 facing the interior of the cabinet. The hot radiator 8 is in contact with the hot face of the Peltier module 11 and is associated with a hot axial fan 7 itself associated with a filter 26 spaced from the fan 7 by a quantity just necessary to minimize the noise emitted by the fan 7. To ensure optimal cooling of the hot radiator while minimizing the noise resulting from the operation of the hot fan, the hot fan comprises an outlet manifold 34 that is oversized with respect to a nominal flow rate of the hot fan. The outlet manifold 34 emerges along a lower rear edge of the cabinet.

A cold radiator 15 has one face in contact with the cold face 23 of the Peltier module and is associated with a cold fan 16 extending inside the sealed enclosure. The cold radiator 15 comprises a rear part 40 embedded in a block of cold foam 12. At the crossing of the rear wall 38 of the tank, sealing is provided by a cold frame 13, here a rigid frame, embedded in the rear wall 38 and associated with a flexible seal 14 (see figure 4 ).

The refrigerated beauty box further comprises a hot shell 35 surrounding the hot radiator, and a rear frame 36 resting on a seal 37 disposed along from the edge of the hot shell 35 (see figure 5 ).

The flexible seals 14 and 37 not only have the effect of minimizing the penetration of hot air into the cabinet, but also minimize the transmission of vibrations to the surrounding wall elements, and therefore reduce the resulting noise.

A temperature regulation sensor 24 is arranged at the base of the front wall 2 and is connected to a control unit 27 arranged at the rear of the box. A hot safety temperature sensor 19 is fixed to the hot radiator 8 and a cold safety temperature sensor 20 is recessed in the cold radiator 15. The safety sensors 19 and 20 are suitably connected to a trigger circuit of the unit. control 27 configured to cut power to the Peltier module when one of the safety sensors reaches a critical temperature.

Furthermore, the cabinet includes a display 30 attached to the front face of the cabinet. The display 30 is preferably a touch screen suitably connected to the control unit 27 to configure the entire installation.

During the initial configuration of the cabinet, an operating temperature setpoint is entered into the control unit 27 by the display 30. The safety temperature setpoints are preferably entered in the workshop, for example 3°C for the temperature cold safety temperature sensor 20, and 40°C for safety temperature sensor 19.

Of course, the invention is not limited to the embodiment described and modifications can be made thereto without departing from the scope of the invention as defined by the claims.

In particular, although the invention has been described in relation to an embodiment comprising fans associated with the radiators, it is possible to provide cabinets comprising only one fan associated with the hot radiator.

When one of the safety sensors has triggered the stopping of the power supply of the Peltier module, provision can be made for a manual or automatic restart after a time delay or depending on the temperature.

The fans can work in both directions, ie they can either blow air on the associated heatsink, or suck air and reject it on the side of the fan opposite the heatsink.
