accompanying a patent application for an industrial invention entitled:

?AIR MANAGEMENT SYSTEM IN THE DOMESTIC ENVIRONMENT?.

DESCRIPTION TEXT

The present invention refers to an air management system in a domestic environment.

Hoods for the extraction of fumes from a hob are known. In particular, extractor hoods are known, in which the treated air is expelled directly outside the building and filter hoods, in which the treated air is returned to the kitchen.

Lately there is a tendency to avoid installing the hood above the hob and instead prefer to integrate it into the hob.

The filter hoods integrated in the hob have air expulsion vents placed between the hob cabinet and the wall behind it or air expulsion vents placed under the hob cabinet, flush with the floor.

However, the hoods of the prior art have various drawbacks.

The air treatment system of the extractor hoods is not? capable of recovering heat, understood as thermal energy accumulated in the hot air produced by the hob. In fact, extractor hoods disperse the hot air outside. Filter hoods, on the other hand, reintroduce the hot air into the kitchen environment, creating an excess of color in the hot season, with the consequent waste of energy in any air conditioning systems. Therefore, depending on the season, there is a considerable waste of potentially exploitable energy.

The hood does not perform efficient filtering of polluted particles present in the air. In fact, the air is treated within the hood only with activated carbon filters to remove odors only, as a filtration more? efficient would require components pi? bulky.

In the case of filter hoods, the expulsion of air between the rear part of the hob cabinet and the wall creates serious hygiene problems, as an unhealthy environment is created which is conducive to the development of mold and bacteria which must not be present in a food preparation area.

If, on the other hand, the air is expelled onto the floor, there is a continuous vortex which suspends all the pollutants present on the floor. In fact, it must be considered that the floor? rich in pollutants carried by users' footwear or by pets. Furthermore, the vortex created by the expulsion of air on the floor circulates all the dust that had settled on the floor, with the risk of irritation of the airways of the user who breathes such dust, and pollution of the dishes prepared or however contamination of all this? which is found in? the environment in which c?? the hood.

Furthermore, the expulsion of air on the ground or under the kitchen worktop creates a curtain of air which hits the user of the kitchen. This situation ? considered an obstacle to comfort in an environment such as the kitchen.

Purpose of the present invention? to eliminate the drawbacks of the known art by providing an air management system in the domestic environment which is practical, versatile, efficient, reliable, economical and simple to install.

These purposes are achieved in accordance with the invention with the characteristics of the annexed independent claim.

Advantageous embodiments of the invention appear from the dependent claims.

Additional characteristics of the invention will appear more? clear from the detailed description that follows, referring to purely exemplifying and therefore non-limiting embodiments thereof, illustrated in the accompanying drawings, in which:

Fig. 4 ? a partially sectioned front view of a second embodiment of the air management system according to the invention;

Figs. 5 and 6 are perspective views, from different angles, of the air management system of Fig. 4 ; And

Fig. 7 ? a pneumatic diagram of the air management system according to the invention.

The air management system according to the invention is described with the aid of the figures, indicated as a whole with the reference number 100.

The air management system (100) includes:

- a hob (2) arranged in a worktop (20) of a kitchen cabinet arranged in a kitchen room (200),

- a hood (1) suitable for extracting fumes from the hob (2), e

- a?unit? controlled mechanical ventilation (VMC) (3) connected to the hood (1) and suitable for treating air sucked in by the hood (1) and introducing treated air into the kitchen room (200).

The hood (1) comprises a casing (10) within which a fan (13) for suction of air and a filter unit (14) for filtering air from the hob are arranged. The filters (14) are generally filters adapted to filter the grease contained in the cooking fumes.

The hood (1) comprises a suction mouth (11) connected, by means of a duct (12), to the casing (10). The suction mouth (11) of the hood ? arranged in correspondence with the hob (2) to extract the fumes that are generated on the hob during the cooking of food.

The CMV (3) ? connected to the casing (10) of the hood by means of a communication duct (4). In this way the air sucked into the casing (10) of the hood is sent to the VMC (3) and treated within the VMC.

An external suction pipe (7) ? connected to the CMV and has an external intake port (70) located outside the house to draw in air from outside.

An exhaust duct (40) ? connected to the VMC (3) to discharge the treated air into the VMC. The exhaust duct (40) ? connected to a discharge mouth (41) located inside the kitchen room (200) to discharge the treated air into the kitchen room.

The VMC (3) comprises a fan (30), a heat exchanger (31) and a filter unit (32).

The heat exchanger (31) ? of the crossed air flow type, so as to cross the flow of hot air drawn onto the hob by the hood, which arrives at the VMC via the communication duct (4) and the flow of air drawn from outside, via the external suction (7).

In this way, during the hot season, the heat exchanger (31) of the CMV is enabled, which cools the hot air sucked into the CMV and emits cooled air at the outlet which is reintroduced into the kitchen.

On the other hand, during the cold season, the heat exchanger (31) of the CMV or in any case the cross-flow with the air from the end is disabled, so that the hot air coming from the hob is reintroduced into the kitchen without being cooled, to heat the kitchen? In this case, as shown in Fig. 7, in the external suction pipe (7) ? foreseen a valve (71) that pu? close the external suction duct.

The VMC filter group (32) advantageously comprises a HEPA filter comprising microfiber filter sheets (generally in borosilicate) assembled in several? layers. The microfiber filter sheets have the task of blocking the solid polluting particles (or particulate) present in the air to be treated.

Advantageously, the discharge mouth (41) ? arranged in an upper part of the kitchen (200) so as not to affect the comfort of the room. For example, if in the kitchen room (200) c?? a piece of furniture (22) for building a refrigerator, the outlet (41) can? be arranged in an upper wall (23) of the cabinet (22) for built-in refrigerator (as shown in Figs. 1-3). In this way, the exhaust duct (40) is arranged within the cabinet (22) for refrigerator build-in and therefore not ? visible.

The hood (1) can? be placed under the hob (2) in the kitchen cabinet which supports the hob (2).

With reference to Figs. 1-3, the CMV (3) can? be a VMC of the dedicated type for a single room. In this case, the CMV can? be placed in the kitchen unit, under the worktop (20) for example under a sink (21), near the hood (1). So the communication duct (4) ? hidden in the kitchen cabinet.

Advantageously, the air management system (100) can comprise at least one internal suction duct (5) connected to the casing (10) of the hood and to an suction mouth (50) arranged in the kitchen room, close to a heat source other than the hob, such as for example an oven, a heater, a fireplace and the like. In this case, as shown in Fig. 7, in the internal suction pipe (5) ? foreseen a valve (51) that pu? close the internal suction duct.

If, for example, in the kitchen c?? an oven built-in cabinet (24), the suction mouth (50) of the internal suction duct can? be arranged in an upper wall (25) of the oven built-in unit.

Figs. 4, 5 and 6 illustrate an embodiment of the air management system (100) in which the CMV (3) ? a centralized VMC of the house that distributes treated air in more? rooms of the house. In this case, the CMV (3) can you? find outside the kitchen room (200), therefore the connection duct (4) must leave the kitchen room, to connect to the CMV (3).

The exhaust duct (40) coming from the CMV (3) must enter the kitchen room (200) from the outside. In this case, the discharge mouth (41) can? be arranged in a roof (6) of the kitchen room (200).

The air management system (100) according to the invention has a series of advantages.

Compared to extractor hoods, the air management system (100) allows, in winter, to recover a large quantity of heat to put it back into the kitchen (200) in the case of distributed CMV or throughout the house in the case of centralized CMV, instead of? wasting thermal energy, such as in extractor hoods.

Compared to filter hoods, the air management system (100) allows, in summer, to remove the heat from the air treated by the CMV so as to reintroduce it into the domestic environment, without increasing its temperature and aggravating the work of any heating system. existing air conditioning or in any case without reducing living comfort.

The VMC allows you to make a filtration at higher efficiencies? higher than hoods. Given that the air treated by the VMC is purified, in the domestic environment there will be more air clean than vacuumed.

The CMV can? also work in place of the fan of the hood, this allows you to optimize the consumption of electricity, since? the VMC has components pi? efficient compared to a hood as pi? optimized.

Suction vents can be integrated at any point of a piece of furniture in the kitchen, above an oven, next to a hob or a microwave oven, in this way the quantity is increased. of treated air that is transformed with characteristics pi? suitable for the health of those who live in the environments.

Compared to the hoods integrated under the hob, the air management system (100) allows you to treat the air in the VMC and channel it to the upper part of the kitchen, solving all the problems due to the creation of an unhealthy environment under the hob or vortices on the floor near the hob.

Equivalent variations and modifications can be made to the present embodiments of the invention, within the reach of a person skilled in the art, which in any case fall within the scope of the invention expressed by the appended claims.
