Description

Cooking fume extractor and lining element for a collecting container of a cooking fume extractor

The invention relates to a cooking hood with a collecting container and a lining element for such a collecting container.

A known solution is to use a hood to clean the fumes and fumes generated during cooking. Dirt, such as liquid droplets (e.g., oil droplets or water droplets) and particles, is removed from the intake air in the range hood. For this purpose, at least one filter element is usually provided in the extraction hood. Depending on the cooking behavior of the user and the ingredients used, low-viscosity dirt, in particular oily dirt, may be deposited on the filter element. This situation occurs, for example, in asian rooms, where asian people have a high oil content when cooking food. In order to prevent such low-viscosity dirt from dripping onto the cooking top located below the extraction hood, it is known to mount a collecting receptacle for the dirt on the extraction hood.

Such a collecting container is described, for example, in DE 102005019830 a 1. In this embodiment, the collecting container is releasably fastened to the floor of the filter device and can be removed in order to empty the filter device.

A disadvantage of the known extractor hood is that, when the collecting container, in particular the liquid level, is removed, the collected dirt can escape from the collecting container. Furthermore, the cleaning of the collecting container is complicated, since the dirt in the collecting container, in particular the oil, can be resinified and can only be removed by intensive cleaning.

In view of the above, it is an object of the present invention to provide a solution for reliably receiving liquid dirt, which is easy to handle for the user.

According to a first aspect, the invention relates to a range hood having at least one collecting container for collecting liquid dirt. The extractor hood is characterized in that it comprises at least one liner having a body arranged in the collection container, and in that the liner has, at least in part, a storage capacity for storing liquid.

The hood means a smoke removing device preferably installed above a cooking top. In particular, the range hood is a so-called chimney, which usually has a stand pipe and a smoke shield. The filter unit refers to a portion of the hood in which at least one filter element is arranged. The filter unit is especially a filter box. In addition to the at least one filter element, the filter unit may also comprise a guide element (e.g. a guide plate) for guiding air or deposited dirt, or a holding structure for holding the filter element. The holding structure may be a frame, for example. The frame may be part of or fixed to the smoke removal housing of the range hood. Thus, the filter unit may be constructed in one piece or in a composite. Preferably, the filter element is arranged obliquely in the extractor hood or the guide element or the retaining structure has an inclination such that it assists in conveying deposited dirt to the collecting container.

Furthermore, the extractor hood has a collecting vessel for collecting liquid dirt. By collection container is meant a container preferably made of a rigid material, such as glass or plastic. The collecting container is provided with a containing cavity for collecting liquid dirt. For collecting liquid dirt, the collecting container preferably has an inlet opening for the liquid to enter the collecting container. The inlet opening is preferably arranged on the top side of the collecting container. In this way, liquid dirt can flow or drip from the filter unit into the collecting container from the top down. In the present invention, the collection container is releasably secured to the filter unit. The collecting container can in particular be fastened to the lower end of the filter element of the filter unit. It is also within the scope of the invention for the collecting container to be fixed to a holding structure of the filter unit for holding the filter element or to the guide element. In any case, the collecting container is preferably arranged in the vicinity of the filter element. The collection container can be removed from the filter unit and from the range hood by releasable fastening.

According to the invention, the extractor hood comprises at least one lining element having a body arranged in the collection container. The liner has at least in part a storage capacity for liquid. According to the invention, the lining element has a body. The lining element can also be provided with a handle and/or a retainer.

Storage capacity for liquids refers to the property of being able to contain and preferably adhere or otherwise retain liquid within the liner material used to construct the body. The liner may have storage capacity throughout its volume. However, it is also within the scope of the invention that only certain liner regions have this storage capability. The body may in particular have storage capacity in the entire volume or only partially.

In the collecting container, at least one lining element is arranged, which at least partially has a storage capacity for liquid, so that several advantages are achieved. In particular, by storing liquid dirt in the insert, in particular in the body, the insert can be removed from the collecting container together with the liquid dirt stored therein, without spilling the dirt during removal of the collecting container and during transport of the collecting container, for example, to a washing tub. Furthermore, by storing liquid dirt in the insert (in particular in the body), dirt can also be prevented or at least reduced from adhering to the collecting container and in particular from resinifying. Thereby further facilitating cleaning and handling of the collection container by the user.

According to a preferred embodiment, the liner and further preferably the body of the liner completely fills the collection container. The lining element in particular preferably completely fills the receiving space of the collecting container. The liner completely fills the receiving chamber of the collecting container at least in the state in which the body of the liner is loaded with liquid. In a region of the collecting container, which is provided with fixing means, for example, for fixing the collecting container to the filter device and which is generally located above the receiving space, no lining, in particular no body, may be provided. The lining element at least completely fills the receiving space of the collecting container, so that liquid in the collecting container is prevented from accumulating on the lining element. Such accumulation of liquid, which may for example be a puddle or pool, can also cause dirt to spill out when the collection container is removed from the range hood and transported to an emptying site.

According to one embodiment, at least two liners are arranged adjacent to each other in the collecting container. This embodiment is particularly advantageous for larger elongated collection containers. By arranging a plurality of liners in the collecting container, the liners are reduced in size and thus easy to handle. In order to prevent in a simple manner a certain part of the liquid-filled liner from breaking off when it is removed from the collecting container.

In the present invention, the shape of the collection container is not limited to a specific shape. The collecting container may for example have a circular or rectangular cross section. The collecting container preferably has a cross section which remains constant from the receiving chamber to an inlet opening which forms the upper edge of the collecting container. The collection container does not taper in particular towards the inlet opening. This simplifies the insertion and removal of the lining element, in particular without the need for pressing the lining element during the above-mentioned steps.

According to a preferred embodiment, the collection container further comprises at least one filter unit, the collection container being releasably secured to the filter unit.

According to a preferred embodiment, the collection container is a flat trough-shaped tray. A flat, trough-shaped tray refers to a collection container of a type whose depth and height are small relative to its length. The advantage of this shape of the collecting container is that the size of the inlet opening formed by the upper edge of the collecting container is maximized by the greater length. The height of the collecting container is small so that it only slightly protrudes downwards out of the filter unit and does not prevent the user from using the hob, which is usually arranged below the extractor hood. Since the depth of the collecting container is small, it takes up only a small portion of the space required by the filter element, which further ensures the smoke removal rate. The invention makes it possible to achieve such a flat trough-like shape of the collecting container, since dirt is prevented from escaping even at low heights during removal and transport of the collecting container by means of the lining elements.

According to one embodiment, the collecting container is fixed to the filter unit by a screw connection, a snap connection or a clamping connection. In these types of connections, a movement of the collecting container which has to be removed from the filter unit is necessary, which movement can be uneven, in particular when the snap connection is released. Nevertheless, the invention makes it possible to use these types of connection, since even in the event of (optionally jerky) movement of the collecting container, there is no fear of spillage of the liquid held therein, since it is stored in the liner.

According to another aspect, the invention relates to a liner for a collection vessel of a range hood. The lining piece is characterized in that the lining piece is the lining piece of the range hood.

The advantages and features described in relation to the range hood of the invention are equally applicable to the liner of the invention and vice versa.

The storage capacity of the liner may be provided by the shape of the material of the liner (in particular the body). For this purpose, the material of the lining element (in particular of the body) may have a cavity for dirt to enter. In the case of small cavities, which are designed as grease or liquid dirt containing grease, the dirt may solidify in the cavity and prevent the liquid from flowing out of the cavity. Alternatively or additionally, the storage capacity can also be provided by the properties of the material of the lining element. The material properties are in particular their tendency to bind liquids. In particular, a material can be used which, for example, comprises fine fibers or consists of such fibers. The liquid can adhere to such fibers and be retained. Furthermore, the material of the lining element can be designed to chemically bind liquids (in particular oils).

In view of this, according to one embodiment, the lining element is made of a porous material. The porous material may be a hard material or a flexible material.

As an alternative or in addition to the porous nature, the liner (in particular the body) may be composed of an absorbent material. An absorbent material refers to a material that is suitable for introducing, containing and storing a liquid, for example, based on the capillary effect. This absorption capacity may be due to the liner material itself. However, according to the invention, the lining material can also be provided with an absorbent, for example a polymer, which serves for storing liquid.

The liner (in particular the body) may be composed of cellulose or plastic. The material of the liner may be, for example, a web or sponge. The liner may thus be a disposable product which can be transported to the washing tank after removal from the collecting container and optionally after initial emptying of the liquid. Alternatively, the lining element can also be cleaned by being fed to a cleaning machine after the initial emptying of liquid in the washing tank. The cleaned liner may then be reinserted into the collection container.

According to a preferred embodiment, the body of the lining element is a shaped body. A shaped body refers to an element that is pressed or otherwise produced into a particular shape and that shape remains unchanged even after receiving a liquid. The shaped bodies form in particular a three-dimensional structure, the height of which is several centimeters. The shaped body may be composed of a plurality of layers.

According to one embodiment, the lining element is liquid-tight on at least one outer side. Outside refers to the side of the liner (in particular the body) which in the mounted state is directed towards the wall of the collecting container. In particular, the bottom side of the lining element which rests on the bottom of the collecting container in the inserted state is an outer side. The other outer side, which is preferably liquid-tight, is a side wall of the lining element. Furthermore, the inner side of the through-opening in the body, through which the fixing element of the collecting container, for example, passes, is likewise the outer side, since in the installed state this inner side is directed towards the fixing element, i.e. towards a wall of the collecting container. According to the invention, the top side of the lining element is not the outer side. The top side is directed towards the inlet opening of the collecting container, i.e. not towards any wall of the collecting container. The top side of the lining element must always be liquid-permeable in order for liquid dirt to enter from the filter unit. At least one of these outer sides of the lining element, in particular the bottom side and optionally at least part of the side walls, is provided with a liquid-tight solution, so that liquid stored in the lining element is prevented from flowing from the lining element into the collecting container. This prevents both contamination of the collection vessel and adhesion of the liner to the collection vessel.

According to one embodiment, the body of the lining element has a liquid-tight coating on the at least one outer side, i.e. the liquid-tightness is achieved by the coating of the lining element on the at least one outer side. The coating may be applied, for example, by dipping. Alternatively or additionally, the lining element sealing on at least one outer side is achieved by compressing the lining element material in this region. This forms a compressed layer or skin from the liner material itself. Such tightness can be achieved by applying pressure and/or by applying higher temperatures.

According to a preferred embodiment, the lining element has at least one handle connected to the body of the lining element. The handle may be embedded in the material of the body of the liner. Alternatively, the handle is fixed to the body of the liner. The handle extends out of a top side of the body of the liner. The top side of the body of the lining element refers to the side which, in the state in which the lining element is installed in the collecting container, faces the inlet opening of the collecting container. The length of the handle is preferably greater than the distance of the top side of the body of the lining element, which is inserted into the collecting container, from the access opening. Thus, the handle extends out of the inlet opening of the collection container. In one embodiment, the height of the body of the lining element corresponds to the height of the collecting container, according to which the handle projects upwards out of the access opening as well. In this way, the user can remove the liner from the collection container without coming into contact with the body of the liner.

According to a preferred embodiment, the handle is releasably connected to the body of the lining element.

The present invention will be described in detail below with reference to the accompanying drawings. In the figure:

fig. 6 is a schematic perspective view of an embodiment of the liner shown in fig. 5 in a state of being loaded into a collection container.

Fig. 1 shows an embodiment of a range hood 1 according to the invention. In this embodiment, the hood 1 is a chimney. The range hood 1 comprises a riser 10 and a connecting smoke shield 11 located below the riser 10. In the bottom side of the smoke barrier 11, a filter unit 12 is inserted into the suction port of the hood 1. In this embodiment, the filter unit 12 includes a filter element 120 in the shape of a truncated pyramid. The truncated pyramid is fitted into the suction port so as to be tapered downward. On the bottom side of the filter unit 12, a collecting container 13 is fixed on the filter element 120. The collection container 13 is filled with a liner, not shown in fig. 1.

Fig. 2 shows a further embodiment of the collecting container 13 and the lining element 14. In the schematic perspective view of fig. 2, this embodiment is in a state where the liner 14 is taken out of the collection container 13. The collecting container 13 has a rectangular cross section in this embodiment. The four side walls of the collection container 13 form a housing chamber 130 of the collection container 13. In this embodiment, two opposite side walls of the collecting container 13 are higher than the other two side walls. On the upper (i.e. longer) side walls, in the upper region, there are mounted in each case one fixing element 131 in the form of a hook 133 which extends outwards. The upper edge of the lower (i.e. shorter) side wall defines the inlet opening 134 of the collection container 13.

In the embodiment shown in fig. 2, the liner 14 has a body 140 and a handle 141 mounted thereto. The body 140 is cuboidal. The width and depth of the body 140 correspond to the width and depth of the receiving cavity 130. The height of the body 140 corresponds to the height of the shorter (i.e., lower) side walls. The lining 14 has a handle 141 which extends upward from the top side of the body 140 and is embedded in the lining material. Preferably, each outer side 143 (i.e., bottom side and four side walls) of the liner 14 employs a fluid-tight solution.

In fig. 3, the embodiment shown in fig. 2 is in a state where the liner 14 is loaded into the collection container 13.

In this state, the collection container 13 may be fixed to a corresponding filter unit (not shown) of the hood. For this purpose, the latching hook 133 can be latched with its corresponding projection on the filter unit, so that the collecting container 13 is held on the filter unit by a snap-on connection.

Fig. 4 shows a further embodiment of a collecting container 13 fitted with a lining element 14. The collecting container 13 is fixed to the filter unit 12, of which only the filter element 120 and the frame 121 holding the filter element are shown. The filter element 120 adopts an inclined arrangement. The filter element 120 rests with its lowest point against the frame 121. The collection container 13 is fixed to the frame 121. In this embodiment, the collection container 13 is fixed to the frame 121 by means of fixing elements 131, which may be threads. In this embodiment, the collecting container 13 has a circular cross-section. The upper edge of the side wall of the collection vessel defines an inlet opening 134 for directing dirt into the collection vessel 13. The body 140 of the lining element 14 likewise has a circular cross section and fills the cylindrical housing chamber 130 of the collecting container 13. In this embodiment, the liner 14 also has a handle 141, which extends upward from the top side of the body 140 of the liner 14 and protrudes out of the access opening 134.

Fig. 5 and 6 show a further embodiment of the collecting container 13 and the lining element 14. This embodiment is substantially the same as the embodiment shown in fig. 2 and 3. In this embodiment, however, the collection container 13 is a flat recess. The side walls of the collecting container 13 all have the same height. Furthermore, the width of the collecting container 13 is much greater than in the embodiment shown in fig. 2 and 3. Furthermore, in the embodiment shown in fig. 5 and 6, the fixing element 131 is designed as a snap arm 132 which extends upward from the bottom of the receiving chamber 130 of the collecting container 13 through the access opening 134. In this embodiment, a number of corresponding through holes 142 are placed into the body 140 in the liner 14. In this embodiment, preferably as in fig. 2, each of the outer sides 143 (i.e., the bottom side and the side walls) of the body 140 and the inner side of the through hole 142 are in a fluid-tight arrangement.

In the state shown in fig. 6, the collecting container 13 may be fixed to the hood, particularly to a filter unit (not shown). The snap arms 132 may snap into corresponding notches on the filter element.

The invention is not limited to the embodiments shown. The shape and dimensions of the collecting container and of the lining element may differ from the solution shown. Furthermore, means other than the shown fixing elements can also be used to fix the collecting container to the filter unit. The filter unit may also differ from the embodiment shown. The filter unit may for example comprise a single filter element which is arranged obliquely to the collecting container.

It is known to produce receiving containers, for example of sheet metal or plastic, which must be emptied and then cleaned in order to remove the remaining residual oil, on which containers careful cleaning is necessary to prevent resinification of the grease, which can have the consequence that these containers cannot be cleaned in the future. The cleaning of the containers is extremely annoying to most users, since it is complicated and almost impossible to avoid contact with the used dirty oil.

The present invention overcomes this problem. According to one embodiment, a liner is inserted into the collecting container, which can also be referred to as an oil container, the body of which is made of an absorbent material (e.g. cellulose) which absorbs and stores the grease and oil produced. Preferably, this lining element is interrupted on the side facing the container by an oil-impermeable layer, so that no grease is released to the container wall via these sides.

Emptying is carried out by simply removing the liner from the collection container. The liner, particularly the cellulose liner, can be transported away while the container remains clean. A new web can be inserted without contact with oil or grease. Such liners do not cause spillage of used oil when the collection container is emptied.

As an alternative to a disposable liner, the present invention may also use a reusable sponge-like plastic liner with closed sidewalls. Such a lining element can be cleaned, for example, in a washing machine after the first emptying.
