Description

[0001] The present invention relates to a cooker hood according to the preamble of claim 1 and an air guidance unit for such a cooker hood.

[0002] EP 2 093 501 A2 describes a range hood comprising a chimney section and a hood body connected to the lower end of the chimney section. The hood body includes a hood plate for directing and / or restricting the direction of gas flow and a receiving space for at least one electrical device. The receiving space comprises an upper receiving space located above the hood plate and a lower receiving space located below the hood plate.

[0003] It is common practice to design cooker hoods so that air is extracted via a gap around a baffle plate. For this purpose, the baffle plate is positioned within a frame, thus creating a gap between the frame and the baffle plate.

[0004] Such a cooker hood is disclosed, for example, in CN 101 126 516 A. In particular, a central cover is detachably provided between the opening edge areas of one of the two sides by a support part that projects down from a top plate of the housing.

[0005] Furthermore, DE 44 41 788 A1 discloses a cooker hood with a hood body. The hood body has one or more baffle plates enclosed by the suction opening at the hood edge. The baffle plate can be heated by a heating device arranged on the baffle plate. Radiators are also provided in the baffle plate.

[0006] Furthermore, such a cooker hood is described, for example, in DE 10 2014 114 926 A1. In this cooker hood, a recessed section is provided on the frame, adjacent to the baffle plate, in which, for example, lighting devices can be installed.

[0007] German patent application DE 20 2007 002 330 U1 describes a device for air conditioning and extracting room air. The air conditioning unit has a substantially plate-shaped hood body with a base arranged above it for mounting on a ceiling or wall and a trough-shaped cover arranged below it, which has a downward-facing window and a filter cavity. A ring light may be arranged in the cover.

[0008] One disadvantage of these extractor hoods is that the lighting elements are located in the airflow and are therefore exposed to the rising steam, which can lead to the accumulation of dirt and grime on the hood. Furthermore, the hood's construction is complex, as the recessed section has to be fitted into the frame. Additionally, the installation space for this recessed section is limited.

[0009] The invention is therefore based on the objective of creating a solution with which, in a simple design of the extractor hood, a space can be created for electronic elements in which the electronic elements are not exposed to the airflow of the extractor hood and the electronic elements can nevertheless act at least partially to the outside or be operated from the outside.

[0010] According to the invention, this problem is solved by a cooker hood with the features of claim 1 and an air guidance unit according to claim 8.

[0011] The invention is based on the realization that this problem can be solved by creating the installation space on the impact plate.

[0012] According to a first aspect, the invention therefore relates to a cooker hood comprising a cooker hood housing in which a fan is arranged, and an air guide unit having a baffle plate located in the area of ​​the extraction opening of the cooker hood housing. The cooker hood is characterized in that an extraction gap is formed between the baffle plate and the cooker hood housing through which air can enter the cooker hood, the air guide unit has at least one cover attached to the side of the baffle plate facing the interior of the cooker hood, and a space for at least one electronic element is formed between the baffle plate and the cover, which is closed on all sides, in which at least one electronic element is arranged, and which is attached to the cover.

[0013] According to the invention, a range hood is defined as a range hood comprising a range hood housing and an air guide unit. The range hood housing includes or consists of a hood. The extraction opening, through which air can enter the range hood, is formed in the hood. Preferably, the range hood also houses the fan, which is also referred to as a blower. However, it is also within the scope of the invention for the range hood housing to further comprise a separate fan housing connected to the hood. In this embodiment, the hood can also be referred to as a fume shield. An air guide chamber is formed in the hood, through which air is directed from the extraction opening to the fan.According to one embodiment, a separate inlet opening can be provided on the extractor hood housing, which is located behind the extraction opening in the direction of flow and through which the air can reach the fan of the extractor hood.

[0014] The extractor hood can, for example, have a horizontally oriented extraction opening, a vertically oriented extraction opening, or an extraction opening that is angled between the horizontal and the vertical. With a horizontally oriented extraction opening, it is located on the underside of the extractor hood. With an extractor hood that has a vertical or angled extraction opening, the extraction opening is located on the front of the extractor hood housing.

[0015] According to the invention, an air guide unit is arranged in the area of ​​the extraction opening, that is, in the extraction opening or offset parallel to the extraction opening, i.e., in the direction of flow in front of or behind the extraction opening. An air guide unit is referred to as being arranged in front of the extraction opening if it is located in the direction of flow of the aspirated air in front of the extraction opening.

[0016] According to the invention, the air guide unit comprises a baffle plate and at least one cover. The air guide unit can also have several adjacent baffle plates. Preferably, a single cover is provided on each of the baffle plates. Therefore, the invention is described below with reference to an air guide unit with a baffle plate and a cover. The cover is attached to the side of the baffle plate facing the interior of the extractor hood. In particular, the cover faces the air guide space extending from the extraction opening into the extractor hood housing or is located within the air guide space. The cover is shaped such that a space for at least one electronic element is formed between the cover and the baffle plate. The cover is shaped to form a body that is open on one side.The cover is connected to the baffle plate via this open side. Thus, the installation space is preferably bounded on one side, particularly the bottom, by the baffle plate and on the other sides by the cover. The installation space is therefore closed on all sides. A recess may be provided in the cover only for cable routing. However, this recess is small, so that even with such a recess, air ingress into the installation space is largely prevented. At least one electronic component is arranged in the installation space. Preferably, several electronic components are arranged in the installation space. The electronic components preferably represent functional elements of the extractor hood.In this context, a functional element is defined as an electronic element related to the primary function of the extractor hood, namely the extraction of air by the fan, or to an additional function, such as the illumination of a portion of the extractor hood's surroundings. At least one of the electronic elements is preferably a lighting module, a control module, or a display module. The lighting module may, in particular, include lighting elements such as LEDs. Furthermore, one of the electronic elements may be a control module and / or a display module. The electronic element may be used to operate the primary function of the extractor hood or an additional function. A display module may also be used to display the primary function and / or an additional function.

[0017] Directional terms such as top, bottom, front, or back refer, unless otherwise specified, to a cooker hood with a horizontal extraction opening when installed. For cooker hoods with a vertical or angled extraction opening, these directional terms must be adjusted accordingly.

[0018] In the extractor hood according to the invention, the cover of the air guide unit is arranged on the side of the baffle plate facing the interior of the extractor hood, for example, an air guide chamber in a canopy hood, thus defining a defined installation space. This allows the electronic components within this space to be reliably protected from contamination. In particular, the baffle plate prevents the electronic components from being directly exposed to the airflow from the extracted fumes. The air entering the interior of the extractor hood through the extraction opening is also prevented from coming into contact with the electronic components due to the cover.

[0019] According to the invention, an extraction gap is formed between the baffle plate and the extractor hood housing, through which air can enter the extractor hood and, in particular, the extractor hood housing. In one embodiment of the extractor hood, where the baffle plate of the air guide unit is located in the extraction opening, the baffle plate is smaller than the extraction opening. This allows an annular gap to be formed around the edge of the baffle plate. If, on the other hand, the baffle plate is located upstream of the extraction opening in the direction of airflow, the size of the baffle plate can be the same as the size of the extraction opening or larger than the extraction opening. In this case, the extraction gap is formed between the side of the baffle plate facing the extraction opening and the side of the extractor hood housing in which the extraction opening is formed. Extraction via the extraction gap is hereinafter also referred to as perimeter extraction.

[0020] According to a preferred embodiment, the cover covers at least part of the baffle plate. The size of the cover can be such that it covers at least half, and more preferably at least three-quarters, of the baffle plate's surface. This large-area coverage results in a large installation space defined by the size of the cover, allowing for the arrangement of a large number of electronic components within that space. Alternatively, the size of the cover can also be smaller. In this case, a compromise can be made between the installation space for component placement and air resistance.

[0021] The cover is preferably positioned centrally on the baffle plate and extends substantially over the entire depth and most of its width. Particularly preferably, the cover extends from the area of ​​the rear edge of the baffle plate to the area of ​​the front edge, ending a short distance from both the front and rear edges. In the width direction, the cover also extends almost the entire width of the baffle plate and ends a short distance from the side edges. In an embodiment where interfaces for connection to the extractor hood are also provided on the side of the baffle plate to which the cover is attached, for example in the form of mounting rails, the interfaces are arranged so that they are attached to the baffle plate laterally to the cover.In this embodiment, the width of the cover will then be at least as much less as the width of the interfaces than the width of the impact plate.

[0022] By preferably covering substantially the entire surface of the baffle plate with a cover – possibly with a recess for interfaces – the electronic components can be arranged on the cover in such a way that they illuminate the desired areas of the baffle plate. For example, a lighting module, as an electronic element, can be located in the center of the cover's surface. If the baffle plate in this area is made of a translucent material, a cooktop located under the extractor hood can be illuminated centrally. Such central illumination is not possible with prior art extractor hoods, in which lighting elements are provided adjacent to the baffle plate within the frame. In the air guidance unit according to the invention, an operating module can, for example, be located in the front area of ​​the cover.If the baffle plate is made of a material that allows the control module to be operated through the baffle plate, then this control module can be easily reached and operated by the user of the extractor hood due to its arrangement in the front area.

[0023] Preferably, at least one of the cover's side walls is at an acute angle to the baffle plate. This design prevents flow resistance as steam flows past the cover. Particularly preferably, the cover has a trough shape with the side walls inclined outwards towards the open side.

[0024] The electronic components can be attached to the baffle plate within the installation space. However, according to the invention, the electronic components are attached to the cover. Attachment to the baffle plate can be achieved, for example, by means of adhesive bonds, such as adhesive adapters. According to the invention, at least one electronic component is attached to the cover. Preferably, the electronic component(s) are attached to the top wall of the cover. Alternatively or additionally, the electronic component(s) can also be attached to the side walls of the cover. Attaching the electronic components to the cover simplifies the assembly of the air guide unit. The cover can be made of metal or plastic, for example. The electronic components can be screwed, clipped, or glued to these materials.The cover, now fitted with the electronic components, can then be placed open-side down onto the baffle plate and connected to it. The cover with the electronic components can thus be pre-assembled. Furthermore, even when the air duct unit is assembled, a gap remains between the electronic component and the baffle plate for electronic components that are shorter than the cover. This prevents the electronic components from touching the baffle plate, thus providing a degree of protection against the high temperatures that can occur on the baffle plate due to the oncoming fumes.

[0025] The impact plate can be made from a wide variety of materials. For example, it can be made of metal or plastic. A metal impact plate may have openings filled with a material that is permeable to waves, especially visible waves or, for example, infrared waves.

[0026] According to a preferred embodiment, the impact plate consists entirely of a translucent material, in particular glass. Using a glass impact plate offers several advantages. Firstly, glass is easy to clean. Secondly, glass has a pleasing appearance. Thirdly, glass has low thermal conductivity, thus protecting the installation space enclosed by part of the impact plate from high temperatures. Finally, a capacitively actuated control module can be operated through a glass plate.

[0027] The impact plate, made of a translucent material, can be colored and / or surface-treated, at least in some areas. Particularly in embodiments where at least one of the electronic elements is an optical element, areas on the impact plate outside the area of ​​the electronic elements can be treated so that no light can pass through them. Other waves, such as IR waves, can also preferably pass through the impact plate. Similarly, in such an impact plate, areas outside the areas of the electronic elements that are actuated by IR signals can be treated so that no IR waves can pass through them.This allows the illumination area generated by a lighting module in the air guide unit to be limited, and, for example, an IR control module, arranged as an electronic component within the installation space, to be reliably operated by remote control. If the electronic component is located on the inside of the baffle plate, it can also be designed as a touch element. In addition, at least one display can be provided by a display module.

[0028] According to one embodiment, the impact plate is surface-treated in areas where no electronic components are present in the installation space above the impact plate. For example, the impact plate can be provided with a coating in these areas, which is omitted in the areas where electronic components are present in the installation space above the impact plate.

[0029] According to one embodiment, the cover is attached to the impact plate by at least one fastening element, which is permanently connected to the impact plate, in particular glued to it. The fastening element can, for example, be an L-profile or a V-profile, one leg of which rests against the impact plate and is permanently attached there. Another leg, inclined towards this leg, projects upwards from the impact plate and can, for example, be used for screwing it to the cover, in particular to one of the side walls of the cover. A V-profile is used particularly in embodiments where the side walls of the cover are at an acute angle to the impact plate.

[0030] The cover is preferably detachably attached to the at least one fastening element, in particular by screws or snap-fit ​​connections. This detachable connection to the fastening element makes it possible, for example, to remove the cover from the baffle plate for repair purposes. After the repair, the cover can then be easily reattached to the permanently fastened fastening elements on the baffle plate. Preferably, the air guide unit has several fastening elements. For example, a rectangular cover may have four fastening elements, which can be arranged either at the four corners or along one edge of each of the four side walls. The fastening elements are preferably attached to the baffle plate in such a way that they are located inside the cover after it has been fitted. This further improves the cleanability of the air guide unit.

[0031] According to one embodiment, at least one recess is provided in the cover. This recess can, for example, serve as a cable outlet. Such a recess is preferably provided in one of the side walls of the cover, for example at the edge where it abuts the impact plate. This simplifies cable routing. The size of such a recess is preferably dimensioned so that it is filled by the cable(s) routed through it.

[0032] A recess can also be incorporated, for example, into the surface of one of the side walls or a top wall of the cover. This recess is then preferably covered with a translucent element. Through such recesses, light can be emitted from the air duct unit to the sides or towards the interior of the extractor hood by lighting modules arranged in the space, thus creating indirect lighting. By covering the recesses with a material, the protection of the electronic components within the space is still ensured.

[0033] According to a further aspect, the invention relates to an air guide unit for a cooker hood according to the invention, wherein the air guide unit comprises a baffle plate and at least one interface for connection to the cooker hood. The air guide unit is characterized in that the air guide unit has a cover which is attached to the side of the baffle plate on which the interface is arranged, and a space for at least one electronic element is formed between the baffle plate and the cover, which is closed on all sides, in which at least one electronic element is arranged and which is attached to the cover.

[0034] Advantages and features described with regard to the extractor hood also apply - insofar as applicable - to the air guidance unit according to the invention and vice versa.

[0035] The air distribution unit is preferably a pre-mountable or pre-assembled unit. This allows the air distribution unit to be attached as a module to an existing extractor hood. Only an interface that can interact with the interface of the air distribution unit may need to be subsequently provided on the extractor hood.

[0036] According to one embodiment, at least one of the interfaces of the air duct unit for connection to the extractor hood is an electrical interface, and at least one interface of the air duct unit for connection to the extractor hood is a mechanical interface. The mechanical interface for connection to the extractor hood preferably represents an interface for connection to the extractor hood housing.

[0037] The mechanical interface can be, for example, a mounting rail to which a joint is preferably attached. The rail can be attached to the baffle plate, in particular glued to it, and the joint can project upwards from the baffle plate. This allows the air guide unit to be articulated to the extractor hood, and in particular held in the extraction opening.

[0038] The side of the baffle plate on which the at least one interface is arranged is preferably the side of the baffle plate which, in the installed state of the air guide unit on the extractor hood, faces the interior of the extractor hood.

[0039] The invention will below be described in more detail with reference to the accompanying drawings. These show: Fig. 1: a schematic representation of a first embodiment of the extractor hood according to the invention; Fig. 2: a schematic representation of a second embodiment of the extractor hood according to the invention; Fig. 3: a schematic representation of a third embodiment of the extractor hood according to the invention; Fig. 4: a schematic sectional view of an embodiment of the extractor hood according to the invention with an embodiment of the air guidance unit according to the invention; Fig. 5: a schematic perspective view into the interior of an embodiment of a cover of the extractor hood and air guide unit according to the invention; Fig. 6: a schematic, perspective top view of an embodiment of the baffle plate of the air guidance unit according to the invention; and Fig. 7: A schematic, perspective top view of an embodiment of the air guidance unit according to the invention.

[0040] In Fig. Figure 1 shows a schematic representation of a first embodiment of the extractor hood 1 according to the invention. This extractor hood 1 is a so-called vertical hood. The extractor hood 1 is mounted above a cooker 2 on a mounting wall 3, which is a room wall. The extractor hood 1 has an extractor housing 10 and an air guide unit 11. In the illustrated embodiment, the extractor housing 10 consists of a fan housing 104 and an adjoining hood 103. A (in Fig. 1. (Not visible) extraction opening. The air guide unit 11 is arranged in the direction of airflow in front of the extraction opening, that is, in front of the front of the extractor hood 10 and in particular the viewing hood 103. The extraction opening is located at the Fig. 1 shown embodiment of the extractor hood, which is a vertical extractor hood, in the vertical position.

[0041] In Fig. Figure 2 shows a schematic representation of a second embodiment of the extractor hood 1 according to the invention. This extractor hood 1 is a so-called angled or head-free hood. The extractor hood 1 is mounted above a cooker 2 on a mounting wall 3, which is a room wall. The extractor hood 1 has an extractor housing 10 and an air guide unit 11. In the illustrated embodiment, the extractor housing 10 consists of a fan housing 104 and an adjoining hood 103. The front of the fan housing 104 lies in a plane that is pivoted forward from the vertical. The adjoining hood 103 is also arranged at an angle. A (in Fig. 2. (Not visible) extraction opening. The air guide unit 11 is arranged in the direction of airflow in front of the extraction opening, that is, in front of the front of the extractor hood 10 and in particular the viewing hood 103. The extraction opening is located at the Fig. 2 shown embodiment of the extractor hood, which is a slanted hood, in a plane inclined to the vertical.

[0042] In Fig. Figure 3 shows a schematic representation of a third embodiment of the extractor hood 1 according to the invention. This extractor hood 1 is a so-called ceiling fan. The extractor hood 1 is mounted above a cooker 2 on a mounting wall 3, which is the ceiling. The extractor hood 1 has an extractor housing 10 and an air guide unit 11. In the illustrated embodiment, the extractor housing 10 consists of a fan housing 104 and an adjoining hood 103. A (in Fig. 3. (Not visible) extraction opening. In the direction of airflow, in front of the extraction opening, that is, under the underside of the extractor hood 10 and in particular the viewing hood 103, the air guide unit 11 is arranged. The extraction opening is located at the Fig. 3 shown embodiment of the extractor hood, which represents a ceiling fan, in the horizontal position.

[0043] In Fig. Figure 4 shows a schematic sectional view of an embodiment of the extractor hood 1 according to the invention, including an embodiment of the air guide unit 11 according to the invention. In this embodiment, which can, for example, represent a ceiling fan, the extractor housing 10 consists only of the hood 103. An extraction opening 101 is formed in the underside of the extractor housing 10. In the illustrated embodiment, the extraction opening 101 transitions into an air guide chamber 105. An inlet opening 100 is provided on the upper side of the air guide chamber 105, which, in the illustrated embodiment, is covered by a filter element 15. A fan 14 is arranged inside the extractor housing 10, i.e., above the inlet opening 100. An air guide unit 11 is provided in the extraction opening 101. The air guide unit 11 consists of a baffle plate 13 and a cover 12 arranged on the upper side of the baffle plate 13.The cover 12 has a downwardly open, tray-like shape. The open side of the cover 12 rests on the top of the impact plate 13. The top wall 121 of the cover 12 lies parallel to the top of the impact plate 13. The side walls 124 of the cover 12 are inclined outwards from the top wall 121. This creates an acute angle between each of the side walls 124 and the top of the impact plate 13. A closed installation space 123 is formed between the impact plate 13 and the cover. In the illustrated embodiment, four electronic elements 120, which represent light modules 1200, are arranged in the installation space 123. In the illustrated embodiment, the impact plate 13 consists, at least in the areas located below the light modules 1200, of a translucent material, in particular glass. Light is emitted downwards by the light modules 1200, which in . Fig. 4 is indicated by the dashed lines. For example, the lighting modules 1200 can illuminate a stove 2 located under the extractor hood 1.

[0044] As can be seen from Fig. As 4 results, the air passage 105 is bounded above by the extractor hood housing 10 and below by the cover 12 and an edge of the top of the baffle plate 13 that projects beyond the cover 12. The baffle plate 13 is smaller than the extraction opening 101. The baffle plate 13 is centered in the extraction opening 101. Thus, a circumferential extraction gap 102 is formed at the edges of the extraction opening 101 between the extractor hood housing 10 and the baffle plate 13.

[0045] The fumes and vapors, drawn in by the negative pressure generated by the fan 14, enter the extractor hood 1 through the extraction gap 102 in the extraction opening 101. Specifically, the fumes and vapors first enter the air duct 105. From there, they are drawn in through the inlet opening 100 of the extractor hood housing 10 via the filter element 15. Because the side walls 124 of the cover 12 are at an acute angle to the top of the baffle plate 13, this airflow is not, or only minimally, disturbed.

[0046] In Fig. Figure 5 shows a schematic perspective view into the interior of an embodiment of a cover 12 of the extractor hood 1 and air guidance unit 11 according to the invention.

[0047] Several electronic elements 120 are arranged in the cover 12. In particular, in the illustrated embodiment, an electronic element 120, representing an operating module 1201, is arranged in the central area of ​​the cover wall 121. Adjacent to the operating module 1201, two electronic elements 120, representing light modules 1200, are arranged on the cover wall 121. These light modules 1200 are oriented so that they emit light in the direction away from the cover wall 121. After the cover 12 is placed on the impact plate 13, these light modules 1200 can therefore be used to illuminate the area under the extractor hood 1. Furthermore, an electronic element 120, representing a display module 1202, is arranged on the cover wall 121. This display module 1202 is also preferably oriented such that signals, such as light symbols, are emitted from the display module 1202 in a direction away from the top wall 121.Thus, after the cover 12 is placed on the impact plate 13, a display can be generated on the impact plate 13. Furthermore, additional electronic elements 120, representing light modules 1200, are arranged in the rear and left edge area of ​​the cover wall 121. A recess 125 is provided in each of the side walls 124. This is located in . Fig. 5 is only visible on one of the side walls. On this side wall 124, preferably as on the left side in Fig. Figure 5 shows an electronic element 120 attached, which represents a light module 1200 and emits light towards the side wall 124 and in particular the recess 125. This allows the interior, in particular the air guide chamber 105 in the hood 103, to be illuminated after the air guide unit 11 has been inserted into the extractor hood 1, thus creating indirect lighting.

[0048] The lighting modules can be, for example, LED modules.

[0049] The invention is not limited to the illustrated arrangement and number of electronic elements 120. Depending on the embodiment, more, fewer and / or different electronic elements 120 can be arranged in the cover 12 and optionally attached to other parts of the cover 12.

[0050] In Fig. Figure 5 also schematically shows fastening elements 17, by means of which the cover 12 can be connected to the impact plate 13. The fastening elements 17 are arranged in the corners of the cover 12 and represent angled V-profiles. One leg of the V-profile rests against the inside of two adjacent side walls 124. The other leg projects into the open side of the cover 12 and, as will be described later, forms the fastening surface for attachment to the impact plate 13.

[0051] In the illustrated embodiment, a recess 122 is provided in one of the side walls 124 in the edge that lies on the open side of the cover 12. This recess 122 serves as a cable outlet.

[0052] In Fig. Figure 6 shows a schematic, perspective top view of an embodiment of the baffle plate 13 of the air guide unit 11 according to the invention. Two interfaces 16 for connecting the air guide unit 11, and in particular the baffle plate 13, are shown on the baffle plate 13. In the illustrated embodiment, each interface 16 comprises a mounting rail 160, which is attached to the top surface of the baffle plate 13. The mounting rail 160 has a hinge at its rear end. Furthermore, in Fig. Figure 6 shows the fastening devices 17, by means of which the cover 12 is attached to the impact plate 13. These are attached according to the positions of the corners of the cover 12 on the impact plate 13.

[0053] By applying cover 12 to the in Fig. The impact plate 13 shown in 6 will be the one in Fig. Figure 7 schematically shows the air guidance unit 11 in a perspective top view. The cover 12 is secured here by screws which are located in the Fig. 6 are only visible as points on the side walls 124 of the cover, attached to the fastening elements 17.

[0054] The present invention is characterized in particular by the fact that a removable cover is attached behind a baffle plate of a range hood. The baffle plate with cover defines an airflow-encapsulated space located between the plane of the baffle plate (which can also be referred to as the design plane) and the plane of the filter element (which can also be referred to as the filter plane). Preferably, the outer shape and surface of the cover are optimized with regard to flow resistance and cleanability. Preferably, the baffle plate is adapted with regard to material, surface, and / or printing to the electronic elements provided in the space (which can also be referred to as functional modules).

[0055] The present invention offers several advantages. Firstly, the extractor hood provides greater design freedom. Within the cover, for example, a variety of combinations of lighting modules and / or display modules can be positioned using simple fastening mechanisms such as adhesives or screws. Furthermore, unlike the prior art, the central placement of electronic components is possible. In addition, user-friendliness is improved, as the surfaces of the air distribution unit can be easily cleaned. Moreover, the robustness and service life of the air distribution unit are increased because the functional modules are protected from the airflow and, in particular, from moisture and grease. Finally, the extractor hood according to the invention can be manufactured cost-effectively. Since cables are protected within the cover, additional cable ducts are unnecessary.Finally, the air distribution unit is a self-contained unit that can be added as a module to an existing range hood. Modifications to the overall design are either unnecessary or minimal.
