Definitions

  • the present invention relates to a household cooking appliance.
  • the present invention aims at solving these and other problems by providing a household cooking appliance as set forth in the appended claim 1.
  • the basic idea of the present invention is to reduce the height of the household appliance by positioning the cooking top supply means (e.g. Venturi tubes, gas flow control valves, current regulators, and the like) along one or more side walls and/or along the bottom wall of the household appliance, thereby reducing the height of the cooking top and increasing, the height of the household appliance being equal, the height of the cavity underneath the cooking top.
  • the cooking top supply means e.g. Venturi tubes, gas flow control valves, current regulators, and the like
  • any reference to "an embodiment” will indicate that a particular configuration, structure or feature described in regard to the implementation of the invention is comprised in at least one embodiment. Therefore, the phrase “in an embodiment” and other similar phrases, which may be present in different parts of this description, will not necessarily be all related to the same embodiment. Furthermore, any particular configuration, structure or feature may be combined in one or more embodiments in any way deemed appropriate. The references below are therefore used only for simplicity's sake, and do not limit the protection scope or extension of the various embodiments.
  • a household appliance 1 is positioned on a kitchen cabinet 2, preferably of the type for embedded household appliances; said cabinet 2 comprises a top 21 supporting the household appliance 1, and doors 22 that can be used for hiding further household appliances, such as, for example, a dishwasher, a washing machine, a refrigerator, or the like.
  • the height of the top 21 relative to the base of the cabinet 2 is preferably comprised between 61 and 100 cm, more preferably approx. 82 cm.
  • the top 21 may comprise an aperture 211 that, as will be further explained in this description, allows the household appliance 1 to be installed into the cabinet 2 in such a way as to improve the utilization of the space available in the premises.
  • the household appliance 1 comprises the following parts:
  • the side walls 113,114 and the back wall 115 preferably have a height that allows a user to load and unload pots on/from the cooking top 12 when the base wall 111 of the household appliance 1 is resting on a top of a cabinet, preferably for embedded household appliances, under which a second household appliance can be placed, e.g. a dishwasher, a refrigerator, a washing machine, or the like.
  • the cooking top 12 comprises retention means (e.g. railings preferably having a maximum height of 5 cm) that can prevent pots positioned on the cooking top 12 from falling onto the top 21.
  • retention means e.g. railings preferably having a maximum height of 5 cm
  • the vertical development of the side walls 113-115 i.e. the height of the household appliance 1, is preferably comprised between 15 and 30 cm, so that the cooking top will lie at a height between 76 and 130 cm, which is the optimal worktop height for people who are 138cm to 210cm tall, i.e. most adult people.
  • the cooking top 12 may be of any type: gas (methane, propane or the like), electric (Joule effect and/or induction), or a combination of said one or more types.
  • the oven 13 may be of any type: microwave, gas, electric, steam, or a combination or one or more of such types (e.g. electric/microwave, gas/electric or other combinations).
  • the oven 13 comprises a muffle 131, inside of which food to be cooked can be placed; said muffle has, for example, a width of 50 cm, so that the whole household appliance 1 will preferably have a total width of 70 cm.
  • the muffle may have a width of 70 cm, so that the whole household appliance 1 will preferably have a total width of 90 cm.
  • the supply means 15 may comprise a Venturi tube and/or a gas flow/concentration control valve and/or an electric regulator capable of varying the voltage and/or current and/or frequency and/or another property of an electric current and/or the like; said supply means are positioned upstream of said heating element and, for a gas cooking top, they perform the task of regulating the flow of fuel (e.g. methane, propane, butane) before said mixture is mixed with an oxidant (e.g.
  • fuel e.g. methane, propane, butane
  • the supply means will vary some properties of an electric current (e.g. frequency, voltage, intensity), so that the heating element will output the correct thermal power. It must be pointed out that, in the electric case, the supply means may perform this thermal power regulation by interrupting the electric current by means of a switch (whether a manual or an automatic one), possibly taking also into account the temperature detected by a temperature sensor (e.g. a thermometer, a thermostat, an infrared sensor, or the like) positioned within or near the heating elements.
  • a temperature sensor e.g. a thermometer, a thermostat, an infrared sensor, or the like
  • the bottom of the muffle 131 may be suitably dished to allow accommodating said supply means without increasing the dimensions of the household appliance 1 on the top 21, so as to better exploit the space available in the premises where said household appliance 1 is positioned.
  • one or more side walls 113-115 may comprise one or more apertures 118, preferably in proximity to the supply means 15, said apertures 118 being so shaped and sized as to allow air to flow through and, preferably, to prevent the user from coming into direct contact with said supply means 15.
  • the positioning of the oven 13 inside the cavity 110 advantageously allows improving the utilization of the available space, because a fairly large oven can thus be arranged where it would otherwise be impossible to place an oven of any kind together with a cooking top positioned at a usable height.
  • the household appliance 1 also comprises electric 116 and/or hydraulic 117 (for gas) supply fittings, which allow feeding the cooking top 12 and possibly also the oven 13 (with gas and/or electric current).
  • electric 116 and/or hydraulic 117 (for gas) supply fittings which allow feeding the cooking top 12 and possibly also the oven 13 (with gas and/or electric current).
  • said hydraulic fittings 117 can also protrude downwards from the wall 111, using the room offered by the aperture 211 in the top 21, so that gas pipes (not shown in the annexed drawings) can be positioned within the cabinet 2.
  • the household appliance 1 and the cabinet 2 can be brought nearer to a wall of the premises where said household appliance 1 is to be positioned, so as to better exploit the available space than would be possible when using a gas cooking range according to the prior art; in fact, in such cooking ranges the gas pipes are arranged along the backside wall, because the bottom wall is usually too close to the floor or even directly laid thereon, and such an arrangement of the fittings reduces the room available for the oven and/or makes it impossible to draw said cooking range near to a wall.
  • the electric supply fittings 116 can be positioned on the bottom wall 111, leading to the same advantages as described above.
  • the fittings 116 and 117 may also be positioned on any side wall, for the purpose of increasing the number of possible installations. This will improve the utilization of the space occupied by the household appliance 1 in the premises where it is located. For example, this arrangement of the fittings allows installing the household appliance even in the absence of an aperture 211.
  • the oven 13 comprises at least one heating element, e.g. a thermal resistor, which can advantageously be positioned as close as possible to the ceiling of the cooking chamber of the oven, i.e. as close as possible to the cooking top 12, thus increasing the usable space within the cooking chamber and improving the utilization of the space occupied by the household appliance 1 in the premises where it is located.
  • a heating element e.g. a thermal resistor
  • the positioning of the heating element in proximity to the ceiling of the cooking chamber, i.e. of the muffle 131, will produce no adverse effects on food cooking, since the reduced height of the side walls of the oven 13 will ensure that any food placed inside the cooking chamber will receive a sufficient amount of heat.
  • the heating element thus arranged will also allow heating the cooking top 12, thereby reducing the quantity of energy consumed by the heating elements of the cooking top 12 for heating foods or pots placed thereon.
  • the cooking top 12 may also comprise a cooking plate 121 (see Fig. 1 ).
  • the cooking plate 121 e.g. a broiler
  • the cooking plate 121 comprises a heating element of its own, preferably an electric one, positioned under it and allowing food to be cooked without adding unsaturated fats.
  • the heating elements of the broiler can advantageously be less powerful than those of prior-art broilers, resulting in smaller dimensions and a larger volume of the cooking chamber - the volume of the household appliance being equal - thereby improving the utilization of the usable room in the premises where the household appliance 1 is located.
  • the heating element of the oven 13 may also be positioned on the bottom of the muffle 131.
  • the muffle 131 may also comprise a rotary plate (particularly useful when the oven 13 is a microwave oven) and/or ventilation means for improving air circulation within the muffle 131 during the food cooking process.
  • the household appliance 1 may comprise a door 16 configured for closing the aperture of the muffle 131 of the oven 13; said door 16 may have either a vertical axis of rotation (as in the example shown in the annexed drawings) or a horizontal one.
  • the space necessary for opening and closing the door i.e. the envelope of the door
  • the space necessary for opening and closing a door with a vertical axis is smaller than the space necessary for opening and closing a door with a vertical axis, thus advantageously improving the utilization of the usable space in the premises where the household appliance 1 is located.
  • the oven 12 comprises also an insulating layer (e.g. made of rock wool or the like) to improve the thermal insulation of the cooking chamber.
  • This insulating layer may have a thickness preferably comprised between 0.5 cm and 3 cm, since the reduced height of the oven 13 reduces the area of heat exchange with the outside environment, and therefore - the volume of the cooking chamber being equal - the dimensions of the whole household appliance 1 can be reduced in order to improve the utilization of the usable space in the premises where the household appliance 1 is located.
  • the insulating layer may be totally absent under at least one portion of the cooking top 12, thus further reducing the height of the cooking top 12 to advantage of the height of the cooking chamber of the oven 13. In addition to this, the removal of the insulating layer will increase the amount of heat yielded to the cooking top 12, thus improving the heating of pots and/or foods placed thereon.
  • the cooking top 12 may also comprise signalling means (not shown in the annexed drawings) configured for signalling to the user when the cooking top 12 has reached a certain temperature, preferably a temperature that might cause skin burns to the user in case of contact with said cooking top 12.
  • signalling means not shown in the annexed drawings
  • the reduction of the thickness of the insulating layer under the cooking top 12 or its (partial) removal will produce an increased temperature of said cooking top 12 when the oven 13 is in operation.
  • These signalling means may comprise grates 17 coated with a thermochromic material that changes color and/or opacity level and/or another optical property with temperature; such grates 17 can be positioned over the cooking top 12, so that pots can be laid thereon.
  • a cover so shaped as to shield at least a part of the cooking top 12, preferably the hottest part thereof (e.g. the broiler), for improved user safety.
  • the household appliance 1 also comprises one or more control panels 14a,14b, which allow controlling the cooking top 12 and/or the oven 13, i.e. the household appliance 1.
  • These control panels 14a,14b preferably have a prevalently vertical development and are preferably so arranged as to partially close the aperture of the cavity 110 along one side of at least one of the side walls 113,114. In this manner, it is advantageously possible to increase the space available on the top wall 112 for the cooking top 12, thereby improving the utilization of the usable space in the premises where the household appliance 1 is located because - the dimensions of the cooking top 12 being equal - the household appliance 1 can be smaller.
  • At least one or more of said control panels 14a,14b may be positioned on the cooking top 12, so as to increase the volume in the cavity 110 and allow, for example, positioning an oven 13 having a larger muffle 131.
  • control panels 14a,14b may comprise control means (e.g. knobs, switches, push-buttons, LCD touchscreens, or the like) mechanically coupled to and/or in signal communication with the supply means 15; the actuation of such control means (e.g. by turning a knob) will affect the state of said supply means (e.g. by increasing the gas flow towards the burners), thus allowing the user to control the operation of said household appliance 1.
  • control means e.g. knobs, switches, push-buttons, LCD touchscreens, or the like
  • the cooking top comprises gas-type heating elements 122
  • at least one of the control panels 14a,14b will comprise a knob 141 operating a valve capable of varying the gas flow towards the burner 122.
  • the gas flow control valve is usually positioned underneath the cooking top, since the distance between said valve and the burner cannot be excessive (at most 10-15 cm) due to load losses.
  • the valve 15 can be positioned along one of the side walls 113,114 and/or along the bottom wall 111, because the reduced height of the household appliance 1 allows positioning the knobs and the valves 15 in proximity to one of the side walls 113,114 and/or to the bottom wall 111, while also being close to the cooking top 12. In this manner, it is possible to reduce the thickness of the cooking top 12 to advantage of the height of the oven 13, thus better exploiting the available space in the premises where said household appliance 1 is located.
  • the top 21 of the cabinet 2 may also comprise a horizontally-pivoted top (not shown in the annexed drawings), to which the bottom wall 111 of the household appliance 1 is secured.
  • Horizontal pivoting systems are normally employed in kitchens for small boats (which are more subject to oscillations caused by sea waves) in order to keep cooking tops and ranges levelled even when the boat is subject to rolling and/or pitching motions.
  • a first variant of the invention comprises a household appliance similar to the household appliance 1 just described, which comprises a coffee-making machine positioned in the cavity 110 in place of the oven 13.
  • This variant offers the same advantages as the main variant, i.e. it provides better space utilization (one household appliance performing two tasks rather than just one) and higher energetic efficiency (a part of the heat produced for making coffee can be reused for preparing foods on the cooking top, and vice versa).
  • a second variant of the invention comprises a household appliance similar to those described for the preceding embodiments, wherein said household appliance comprises a coffee-making machine positioned in the cavity 110 together with an oven similar to the oven 13.
  • components can be shared between the coffee-making machine and the oven (e.g. a part of the heating element of the oven can also be used for heating the water used for making coffee), thus providing better space utilization and higher energetic efficiency of said household appliance.
  • a third and last variant comprises a household appliance similar to those described for the preceding embodiments, wherein said household appliance comprises also a hood, preferably of the filtering type, positioned over the cooking top and secured, through support means (such as, for example, a hollow box-shaped housing or a panel), to the top wall 112 and/or to one or more of the side walls 113-115, weighing upon them, so that the rigidity of said walls is exploited for bearing the weight of said hood.
  • support means such as, for example, a hollow box-shaped housing or a panel
  • the hood is more effective than prior-art solutions, because said hood must be positioned at a shorter distance from the cooking top 12 due to the limited strength of the side walls 113-115, thus advantageously reducing the quantity of fumes and/or vapours not aspirated and/or treated by it.
