Description

Technical Field

[0001] The invention relates to a range hood device and a system for mounting and an assembly kit for assembling such a range hood device. Background Art

[0002] It is known to introduce a range hood into a worktop. Here, the range hood can be adjacent to the cooktop or integrated into the cooktop. In these range hoods, for example, fumes and smoke that occur during cooking are sucked in through a recess in or near the cooktop. The fumes and smoke are cleaned by a filter and released again as cleaned air through the air outlet opening of the range hood.

[0003] Such a range hood can be embodied as a recirculating air appliance. A recirculating air appliance is a range hood in which the air escaping from the air outlet opening can be released again into the room in which the range hood is operated, in particular into the kitchen.

[0004] Alternatively, it is known to operate such a range hood device as an exhaust device. In this case, the air escaping from the air outlet opening of the range hood device is released into the surroundings through an exhaust duct, for example through a wall cover in the room wall.

[0005] It is known to use odor filters for circulating air appliances. In particular, activated carbon filters are used to free the air from odorous substances before the air is introduced back into the room.

[0006] If such a recirculation air device is connected to an exhaust air duct, it is disadvantageous in many aspects. In particular, the functionality of the filter material or the odor filter wears out or decreases over time without generating any benefit for the user. Summary of the invention

[0007] It is therefore an object of the present invention to provide a solution by means of which a range hood appliance can be converted into an exhaust air device in an efficient manner and can be operated in exhaust air mode.

[0008] According to a first aspect, the object is achieved by a range hood device having a connected ventilation duct, wherein the range hood device is designed for installation in a kitchen appliance and comprises: an air inlet opening, which is located in the upper side of the range hood device; and an appliance housing, which is arranged below the air inlet opening and has an air outlet opening in a side wall; and a blower, which is arranged in the appliance housing. The range hood device is characterized in that the range hood device comprises at least one noise filter element, which is received in the appliance housing and whose filter material is chemically inert.

[0009] The range hood device is preferably a range hood device integrated into the cooktop. The range hood device has an appliance housing. A blower of the range hood device, which can also be called a ventilation device, is arranged in the appliance housing. The range hood device has an air inlet opening, which is located in the upper side of the range hood device. In the case of a range hood device integrated into the cooktop, the air inlet opening can be formed by a cutout in the cover plate of the cooktop. In the case of a range hood device separated from the cooktop, the air inlet opening can be formed by a cutout in the upper side of the kitchen furniture, especially the work plate, where the range hood device is installed. This type of air inlet opening exists in an embodiment in which the appliance housing is open upward. If the appliance housing is closed upward, the air inlet opening is introduced into the upper side of the appliance housing. In this case, the air inlet opening is oriented with a cutout in the cover plate of the cooktop or the work plate. By locating the air inlet opening in the upper side of the range hood device, air can be sucked downward into the range hood device through this air inlet opening. The device housing, in which the blower is preferably accommodated in the blower housing, is located below the air inlet opening. Here, in a vertical top view of the air inlet opening, the air inlet opening of the blower housing can be located in the air inlet opening or horizontally offset relative to the air inlet opening.

[0010] The appliance housing has at least one air outlet opening. The air outlet opening is arranged in a side wall of the appliance housing. Preferably, the air outlet opening is arranged in a rear wall of the appliance housing, which, after the installation (which can also be referred to as mounting) of the range hood device, faces the room wall behind the kitchen furniture. The air outlet opening of the appliance housing can be oriented with the air outlet opening of the blower housing. Preferably, the air outlet opening is located in the air outlet opening.

[0011] In the case of a cooker hood device integrated in a cooker, the heating module of the cooker is preferably also accommodated in the appliance housing. The air outlet opening is used to discharge or blow out the cleaned air from the cooker hood device. The kitchen furniture, which can also be referred to as a furniture unit, in which the cooker hood device is installed, is preferably in the form of a kitchen cabinet. The kitchen cabinet is preferably located at the room wall and has no rear wall.

[0012] The ventilation duct connected to the cooker hood device is embodied as an air guide. Preferably, the ventilation duct is embodied as an exhaust air channel, through which the air escaping from the air outlet opening can be guided to an air outlet end of the ventilation duct, which is spaced apart from the cooker hood device. After being assembled for exhaust operation, the air outlet end of the ventilation duct is preferably located in a room wall or a house wall and can be connected, for example, to a wall cover.

[0013] The range hood appliance is characterized in that it has at least one noise filter element which is accommodated in the appliance housing and whose filter material is chemically inert.

[0014] The following filter elements are referred to as noise filter elements, by which noise can be reduced. In particular, noise can be suppressed by the noise filter element. However, the noise filter element can also be used for noise attenuation. Therefore, the noise filter element can also be referred to as a muffler. Here, in particular, the operation of converting sound energy into vibration waves in the inaudible range is understood as "noise suppression". In particular, the operation of preventing sound waves from spreading by reflection in the adjacent space is understood as "attenuation". The noise filter element is received in the device housing, that is, it is arranged in the device housing.

[0015] According to the invention, the filter material of the noise filter element is chemically inert. According to the invention, a material is referred to as chemically inert if it does not react or reacts only to a very small extent with the air flow sucked into the appliance housing. In particular, the filter material does not react chemically with the air and the gaseous dirt contained in the air flow nor with the particles contained in the air flow. In contrast, in the case of an odor filter, in particular an activated carbon filter, the filter material, in particular the activated carbon, reacts chemically at least with the gaseous dirt in the air flow passing through it. The noise filter element can preferably be referred to as being free of activated carbon.

[0016] By having a noise filter element in the range hood device, it is possible to prevent the user of the range hood device from being disturbed by the noise that occurs in the range hood device. In particular, the noise that occurs due to the operation of the blower can be suppressed and / or attenuated. By arranging the noise filter element in the appliance housing (in which the blower is also arranged), it is possible to achieve noise reduction in the immediate vicinity of the location where it is generated and thus prevent the transmission of noise to other components, which would be the case if the noise filter element is connected after the appliance housing. In addition, by virtue of the fact that the filter material of the noise filter element is chemically inert, the chemical properties of the noise filter element will not change during operation, and therefore no reduction in the functionality of the filter material or exhaustion of the filter material will occur. Therefore, no resources will be wasted.

[0017] According to one embodiment, the filter material of the noise filter element consists of plastic, in particular polyethylene terephthalate, PET. These materials are advantageous because they can be easily shaped in the desired form. This simplifies the manufacture of the noise filter element on the one hand and the function of the noise filter element can be reliably achieved by purposefully setting the form on the other hand.

[0018] According to one embodiment, the filter material exists as a granular material, in particular as a granular material. As an alternative or additional solution, the filter material can also exist as a nonwoven. If a granular filter material, in particular a granular material, is used as a filter material, the filter material can be present in the noise filter element in the form of being introduced into a sheath. For example, a nonwoven sheath can surround a layer composed of granular material. Alternatively, the granular filter material can also be kept between the grids. The filter material can alternatively be made only of a nonwoven layer. The granular material and / or the nonwoven are preferably made of PET. Due to the use of a granular filter material, the number of discontinuities in the noise filter element will be higher and therefore prevent the diffusion of noise through reflection. The number of discontinuities is also higher in the case of a nonwoven material.

[0019] According to a preferred embodiment, the noise filter element has at least one pleated pad, which is at least partially composed of filter material. The pad can consist only of filter material. Alternatively, the pad can have a coating or covering layer at its surface. This coating or covering layer can be made of a material different from the filter material. The pad is preferably pleated. A pad that is at least partially and preferably completely folded is called pleated. In order to stabilize the pleated shape of the pad, the pad can be at least partially included by a frame. In particular, at least the edge of the pad perpendicular to the longitudinal extension of the fold can be shielded by the frame. But it is also possible that all edges of the pleated pad are shielded by the frame. Here, the frame surrounds the pleated pad on all sides. The frame can be made of the same material, such as filter material. In particular, the frame can be made of PET.

[0020] By using a pleated mat made of filter material, the available filter area can be optimized given the predetermined outer dimensions of the noise filter element. In particular, a pleated mat with a size of 0.1 m can be introduced into the frame. 2 A mat of 194 mm in length, 75 mm in width and 34 mm in height can be produced for this purpose. For example, 24 folds can be produced in the mat. Since, in addition, the thickness of the mat itself can be small in the case of a pleated mat, a relatively low pressure difference can be achieved with the noise filter element. At 150 m 3 At a delivery capacity of 100 m / h, for example, a pressure difference of ≤50 Pa can exist. Due to this low pressure difference, the blower can be operated at low power, so that the noise generation is reduced.

[0021] According to one embodiment, the noise filter element is located behind the air inlet opening of the range hood device in the flow direction and before the blower of the range hood device. Through this arrangement of the noise filter element, the noise filter element can reduce the noise leakage through the air inlet opening. According to one embodiment, at least one noise filter element can be arranged behind the grease filter element in the flow direction. For example, one or more grease filter elements can be combined in the filter unit. According to one embodiment, for example, two filter elements are arranged relative to each other in a V-shape and are held in a common carrier. The noise filter element can be arranged, for example, on the outside of the grease filter element in this embodiment. The noise filter element can be received and held in a filter receiving portion, which can, for example, be in the form of a rail or in the form of a frame that is completely open to one side.

[0022] According to one embodiment, the range hood device includes at least two noise filter elements. Here, each noise filter element preferably has a length less than the length of the air inlet opening of the range hood device. At least two noise filter elements preferably abut each other at their end sides, and the total length of the noise filter element-combination is greater than the length of the air inlet opening. In this embodiment, the air inlet opening preferably has a rectangular shape. The noise filter elements are respectively represented as cuboids with a length greater than the width. For noise filter elements with pleated pads, the dimension preferably parallel to the folding structure is called width and the dimension perpendicular to the folding structure is called length. Through the noise filter element-combination formed by two noise filter elements, although the total length is greater than the length of the air inlet opening, the combination can be introduced into the range hood device through the air inlet opening and also removed through this air inlet opening. The air inlet opening preferably extends in the depth direction of the range hood device and especially the stove. The noise filter element can preferably have a connecting piece fastened at one end wall of the end wall of the noise filter element or two connecting pieces fastened at the opposite end sides of the noise filter element. The noise filter element can be handled better by means of this connecting piece, in particular aligned in the range hood appliance and removed from the range hood appliance.

[0023] According to one embodiment, the ventilation duct has at least one duct element. If the ventilation duct has a plurality of duct elements, the ventilation duct can be produced by plugging the duct elements together.

[0024] Preferably, the ventilation duct has a straight channel element, which is partially introduced into the air outlet opening of the appliance housing. Therefore, the size and shape of the cross section of the channel element correspond to the size and shape of the cross section of the air outlet opening of the appliance housing. Preferably, the size of the cross section of the channel element is smaller than the size of the cross section of the air outlet opening. As a result, there is a gap between the outer periphery of the channel element and the inner periphery of the air outlet opening. It is particularly preferred that a sealing strip is applied to the outer periphery of the channel element, by which the gap is sealed.

[0025] The straight channel element can be a pipe and have, for example, a rectangular cross section. The end of the straight channel element that is opposite the end of the channel element that is introduced into the air outlet opening is also called the free end of the channel element. This free end can be introduced into an opening in the room wall behind the range hood device. Preferably, the free end is connected to the wall cover.

[0026] In addition to the straight channel element, the ventilation duct can also have at least one curved channel element. By having at least one straight and at least one curved channel element, a possible given vertical or horizontal deviation of the opening in the chamber wall and the air outlet opening of the appliance housing can be eliminated.

[0027] The range hood device is shown as an exhaust device in the embodiment of the ventilation duct, which is connected to the room wall or the house wall. Since the air from the ventilation duct is released into the surrounding environment through the wall cover as necessary, there is no need for an odor filter as is necessary in the circulating air device.

[0028] According to another aspect, the invention relates to a system for installing a range hood in a kitchen appliance, wherein the system comprises a range hood having: an air inlet opening, which is located in the upper side of the range hood; and an appliance housing, which is arranged below the air inlet opening and has an air outlet opening in the side wall; and a blower, which is arranged in the appliance housing. The system is characterized in that the range hood has: an interface for a ventilation duct to be releasably connected, which interface is formed at the air outlet opening; and at least one filter receptacle for a filter element, which is arranged in the flow direction after the air inlet opening and before the blower, and the system further comprises a ventilation duct and at least one filter element. The filter receptacle can also be referred to as a filter holder.

[0029] The advantages and features described with respect to the range hood device according to the invention also apply, as far as applicable, to the system according to the invention and the assembly kit according to the invention, and vice versa. The assembly kit will be described in more detail later.

[0030] A system with a range hood device, which has an interface for a ventilation duct to be connected in a releasable manner and at least one filter receptacle for releasably receiving at least one filter element, provides a number of advantages. On the one hand, not only the at least one filter element but also the ventilation duct can be removed and replaced from the filter receptacle or the interface, and thus can be removed and replaced from the range hood device. This is not only advantageous for cleaning the filter element or maintaining the ventilation duct. More precisely, by means of this modular structure, the range hood device can be operated either in exhaust mode or in circulation mode without structural changes to the range hood device itself, in particular the housing of the device.

[0031] According to one embodiment, the system therefore includes a ventilation duct composed of a channel element for inserting into the interface of the range hood device and at least one noise filter element for being introduced into at least one filter receiving portion. The interface for the ventilation duct is formed by the air outlet opening of the appliance housing. The end of the channel element that should be introduced into the air outlet opening therefore preferably has the following cross-section, the size and shape of which correspond to and are preferably slightly smaller than the size and shape of the cross-section of the air outlet opening. Here, the gap between the air outlet opening and the channel element is sealed according to the present invention by a sealing strip also referred to as a sealing ring. At least one noise filter element has such a size and shape that this noise filter element is at least partially introduced into the filter receiving portion of the range hood device and can be kept there. Preferably, at least two noise filter elements can be introduced into a common filter receiving portion. In particular, two noise filter elements can be abutted against each other with their end sides facing each other.

[0032] If the range hood device is equipped in such a way that it forms a circulating air device, wherein a ventilation duct for circulating operation is introduced into the interface and one or more odor filter elements are arranged in the filter receiving portion, then according to the present invention, this state can be changed in a simple manner by the user so that the range hood device is placed in an exhaust state. For this purpose, it is only necessary to remove one or more odor filter elements and introduce one or more noise filter elements into the filter receiving portion and replace the ventilation duct. In particular, a channel element of the circulating air channel, that is, a channel element of the ventilation duct (the free end of the channel element points to the space where the range hood device is running, and the channel element is introduced into the air outlet opening) can be pulled out from the air outlet opening, and an exhaust channel, in particular a straight channel element, can be introduced into the air outlet opening instead of the channel element and connected to the opening in the room wall.

[0033] According to another aspect, the invention therefore relates to an assembly kit for a range hood appliance of the mounting system according to the invention, wherein the assembly kit is characterized in that the assembly kit comprises a ventilation duct consisting of a channel element and at least one noise filter element. With such an assembly kit, a user can easily convert a range hood appliance equipped as a circulating air appliance into a range hood appliance for exhaust air operation.

[0034] Unless otherwise indicated, directional terms such as front, rear, top and bottom relate to the range hood and its components when they are installed in the furniture unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] exist Figure 1 1 shows a schematic block diagram of an embodiment of a range hood device 11. In this embodiment, the range hood device 1 is integrated into a cooktop 10. The cooktop 10 and the range hood device 11 are collectively also referred to as a combination appliance 1 below. The combination appliance 1 is installed in a kitchen furniture 4, also referred to as a kitchen cabinet 4. The kitchen cabinet 4 has a work panel 40 at the upper side, which defines the interior of the kitchen cabinet 4 upward. At the side, the interior of the kitchen cabinet 4 is defined by side walls, of which only one side wall can be seen in FIG. 1. The interior of the kitchen cabinet 4 is open to the rear in the embodiment shown.

[0047] The combined appliance 1 consists of a cooktop 10 and an integrated range hood device 11. The cooktop 10 has a cover plate 101. A cooktop housing can be arranged under the cover plate 101, and the cooktop housing has a heating module (not shown) arranged therein. In the cover plate 101, a cutout 102 is provided in the middle region of the cover plate 101, and the cutout has a rectangular shape.

[0048] The range hood device 11 comprises a range hood housing 110 and a ventilation duct 2. The range hood housing 110 of the range hood device 11 is arranged below the cooktop 10. A blower housing 112 for a ventilation device (not shown) is formed in the range hood housing 110. The ventilation device is preferably a radial ventilation device. The blower housing 112 is designed so that the ventilation device axis of the ventilation device is in a vertical state. This is Figure 1 In the upper side of the range hood housing 110 and in particular the blower housing 112 (which faces the lower side of the cooktop 10 and partially rests against it), an air inlet opening (not shown) is introduced. Air can enter the blower housing 112 from above through the air inlet opening.

[0049] For better recognition of the components of the cooker hood device 1, Figure 1 In the figure, the cutout 102 is shown along the width direction of the cover plate 101 of the cooktop 10. However, it is preferred that the cutout 102 is along the depth direction of the cover plate 101 (see Figure 2 and Figure 3 )extend.

[0050] The air inlet opening 113 of the range hood device 11 is formed by the recess 102 of the cover plate 101 of the cooktop 10 in the embodiment shown. The grease filter unit 116 is introduced into the air inlet opening 113 or the recess 102. A grease filter element (not shown) is arranged at the side of the grease filter unit 116. Noise filter elements 3 are arranged outwardly offset relative to the grease filter unit 116, which are parallel to the grease filter in the embodiment shown and are respectively retained in the filter receiving portion 115. The filter receiving portion 115 is formed by a frame open to the filter receiving portion 115 in the embodiment shown, and the frame can be flowed through by air. In the embodiment shown, the filter receiving portion 115 and the noise filter element 3 arranged therein can be flowed through in a horizontal direction.

[0051] The appliance housing 110 has an air outlet opening 114 which, in the embodiment shown, is formed by an air outlet opening of the blower housing 112 and is located in the rear side of the range hood device 11 .

[0052] The ventilation duct 2 is connected to the air outlet opening 114. Figure 1 In the embodiment shown, the ventilation duct 2 consists of a channel element 20 which is designed as a straight channel element 20. The free end of the ventilation duct 2 is introduced into an opening in the chamber wall R.

[0053] exist Figure 2 and Figure 3 The stereogram shows the Figure 1 The range hood equipment 11. Here and Figure 1 In contrast, the orientation of the recess 102 is shown in the depth direction of the cover plate 101 of the cooktop 10. This is the preferred orientation of the recess 102. The further elements, the grease filter unit (not shown in FIG. 2 ), the filter receptacle 115 and the noise filter element 3 therefore also extend in the depth direction.

[0054] exist Figure 2 and Figure 3 The steps of assembling the range hood device 11 are shown in FIG. Figure 2 and Figure 3 The introduction of the noise filter elements 3, 3' is shown in . In the embodiment shown, two noise filter elements 3, 3' are provided for each filter receptacle 115. In this case, the noise filter elements 3 and 3' have the same structure.

[0055] The noise filter element 3, 3' can have, for example, Figure 4 and Figure 5 The structure shown in . Each noise filter element 3 has a rectangular parallelepiped shape. The noise filter element 3 has a frame 31 in particular, in which a pleated mat 31 made of filter material, in particular PTE, is held. The noise filter element 3 has a length that is greater than the width of the noise filter element 3. The dimension in the direction in which the noise filter element 3 can be flowed through is called the depth of the noise filter element 3. Figure 5 In the figures, the depth of the noise filter element therefore refers to the dimension in the plane of the drawing.

[0056] On the side walls, which are also referred to as end walls, the noise filter element 3 each has a web 32 . The web 32 projects beyond the frame 31 .

[0057] If Figure 2As a result, in a first step, two noise filter elements 3 (the two noise filter elements in the assembled state represent the noise filter elements 3 at the front) are introduced into the interior of the cooker hood device 11 through the recess 102 in the cover plate 101. Here, the noise filter elements 3 are oriented so that their length is in the longitudinal direction of the recess 102. After it is located under the recess 102, the noise filter element 3 on the left is pushed to the left, and the noise filter element 3 on the right is pushed to the right. As a result, the noise filter element 3 is introduced into the filter receptacle 115. The noise filter element 3 is then pushed forward in the filter receptacle 115. This movement Figure 2 Indicated by block arrows in FIG. 3 . With the noise filter element 3 at the front, two further noise filter elements 3 ′ are subsequently introduced into the cooker hood device 11 through the recess 102 in a position placed in the front region of the filter receptacle 115. After the noise filter elements 3 ′ have entered the interior of the cooker hood device 11 through the recess 102, they are pushed outwards, as schematically indicated by block arrows in FIG. 3 .

[0058] In the fully assembled state, the two noise filter elements 3, 3' are therefore located in each of the filter receptacles 115. Here, the noise filter elements 3, 3' are resting against each other with their end faces. Figure 2 and Figure 3 The connecting piece 32 (not visible in the figure) protrudes beyond the noise filter element 3, 3' in the direction of the middle of the recess 102. As a result, after the noise filter element 3, 3' has been introduced into the filter receiving portion 155, the connecting piece 32 can also be obtained by the user by reaching into the recess 102, and the noise filter element 3, 3' can be removed from the filter receiving portion 115.

[0059] exist Figure 6 1 shows an embodiment of an assembly kit 5 which can be provided for a range hood device 11. The assembly kit 5 comprises four noise filter elements 3, 3' and a ventilation duct 2 in the form of a straight channel element 20. At the end of the channel element 20, a sealing strip 25 is shown which is placed around the outer circumference of the channel element 20 and is fixedly bonded to the outer circumference. This is schematically shown in FIG. Figure 6 After installation, the sealing strip 25 is preferably spaced apart from the end of the channel element 20 by a distance of, for example, 5 mm. Figure 7 Shown in.

[0060] exist Figure 8 It is shown in Figures 1 to 31. The air outlet opening 114 can be seen on the rear side of the range hood device 11. The channel element 20 is inserted into this air outlet opening 114 with the sealing strip 25. This is indicated by the block arrow Figure 8 Shown in.

[0061] As explained above, the invention allows a range hood device 11 designed for circulation operation to be easily converted for exhaust air operation.

[0062] exist Fig. 9 and Fig.10 1 shows a range hood device 11 for circulation operation. The range hood device 11 for circulation operation differs from the range hood device 11 according to the invention or realizable according to the invention for exhaust air operation in that the ventilation duct 2 has a different shape and an odor filter element (not visible) is introduced into the filter holder instead of a noise filter element.

[0063] The ventilation duct 2 for circulation operation is Fig. 9 and Fig.10 . This ventilation duct is composed of a flat channel element 20 introduced into the air outlet opening 114 of the range hood device 11. In addition, the ventilation duct 2 has a first curved channel element 21, which can also be called the input bend of the ventilation duct 2. Through this curved channel element 21, the air flow can be turned from horizontal to vertical. Another channel element 22, which is a straight channel element, is connected to the input bend. Therefore, air enters the vertical part of the ventilation duct 2 from the input bend. Another curved channel element 23, which can also be called the output bend, is connected to the vertical part. Therefore, air enters the output bend from the vertical part, in which the air flow turns from vertical to horizontal. Air enters the diffuser 24 from the output bend. Therefore, through the diffuser 24, air can be released in the base gap between the bottom 41 of the kitchen cabinet 4 and the kitchen floor during the circulation operation of the range hood device 11. The base gap is generated by the foot 42 of the kitchen cabinet 4.

[0064] Such a range hood appliance for circulation operation can be easily converted into a range hood appliance for exhaust air operation using the assembly kit according to the invention, without having to carry out structural measures with respect to the range hood appliance itself, in particular the appliance housing.
