The odor sensor is configured to detect Volatile Organic Compounds and to send a signal when a threshold of these Compounds is reached. - The
range hood 2 further comprises a display and/or notification lights, a speaker or other input/output devices. - The
oven 3 is a self-cleaning pyrolytic oven which uses high temperature to burn off leftovers from baking, without the use of any chemical agents. - The
oven 3 comprises a power unit and heating elements configured to cook but also to perform a pyrolysis process and a temperature sensor configured to detect temperature inside theoven 3. The temperature sensor is connected in signal communication to the respective localelectronic control unit 200 of theoven 3 and therefore to the components of the local-area communication network. - The
oven 3 comprises also a catalyst device which is configured to oxidize carbon monoxide, deriving form pyrolysis, into carbon dioxide before discharging into the room/kitchen. - The
kitchen hob 7 comprises a power unit and heating elements for cooking. The odor sensor may be installed on thekitchen hob 7 instead that on therange hood 2. - The
household range hood 2, theoven 3 and thekitchen hob 7 are connected or configured to be connected in signal communication to each other though the communication network. - The local
electronic control units 200 of theappliances remote device 11 are part of, or form, an electronic control unit of theelectrical household system 1. From a different viewpoint, the electronic control unit of theelectrical household system 1 comprises several portions which may be integrated into the appliances. - A household range hood system comprising the
household range hood 2 with the localelectronic control unit 200 and theremote device 11 is part of theelectrical household system 1 and is also object of the present invention. - According to a method of controlling the
household range hood 2, to a method of controlling theelectrical household system 1 and to a use of theremote device 11 according to the invention, the application (App) is so structured and configured to allow a user to program thesuction device 100 and/or thelight source 300 and/or further electric loads of therange hood 2 through theremote device 11. This way it is possible to schedule operation modes and/or working times of thesuction device 100 and/or oflight source 300 during a time period. - The operation modes of the
light source 300 set through the remote device may comprise: light source on, light source off, light source power level, light source temperature/colour. Furthermore, power level and/or temperature/colour may be changed and/or dimmered from a working time to another and also during a working time. - The working times set through the electronic control unit and/or the remote device may be comprised between one second and one day. The time period may be comprised between one hour and one year. It is thus possible to schedule working times (time bands or seconds, minutes or hours) during a day or during a month, a week or a year.
- By way of example, the
range hood 2 may be programmed such that every day (time period) thelight source 300 is shut off (first operation mode) during day (first working time) and it is turned on with a warm tone (second operation mode) every night (second working time) as a courtesy light. - A screenshot of the application with a programmable timer or scheduler according to the invention is shown in
FIG. 2 . -
FIG. 2 shows that thelight source 300 of therange hood 2 is programmed to be a night light with a warm tone during every night, from 2:55 AM to 6:55 AM. - According to a different programmed schedule, every day (time period) the
light source 300 may change stepwise through the day and/or night. - The
suction device 100 may be also programmed, e.g. to perform ambient air filtering and/or changing the air in the room/kitchen once in a while. By way of example, air filtering and/or changing may be performed every day at 02:00 PM and 22:00 PM just after lunch and dinner. - The programmed function may be bypassed by the manual actuation of the
suction device 100 and/or of thelight source 300. In other words, the electronic control unit and/or the remote device is/are configured to override the set operation modes and/or working times programmed when the user, through the input devices of theremote device 11 or of therange hood 2, switches on or off or changes the parameters of thesuction device 100 and/or of thelight source 300. - According to the method of controlling the
household range hood 2, to the method of controlling theelectrical household system 1 and to the use of theremote device 11 according to the invention, the application (App) is so structured and configured to control power of thesuction device 100 as a function of parameters of thekitchen hob 7 and/or of theoven 3. - A screenshot of the application showing synchronization buttons/sliders with the
kitchen hob 7 and/or of with theoven 3 is shown inFIG. 3 . - Even if the
suction device 100 and/or thelight source 300 of therange hood 2 are programmed to follow a scheduled program, such program is bypassed when theoven 3 and/or thekitchen hob 7 are activated (manually or automatically) in a cooking mode. - In particular, when the
oven 3 and/or thekitchen hob 7 are activated in the cooking mode, thesuction device 100 and preferably also thelight source 300 are automatically switched on and set in a respective cooking mode (e.g. with a predefined suction power and with a specific illumination of the hob 7). Furthermore, in the cooking mode, the power of thesuction device 100 may be automatically adjusted as a function of detected power of thekitchen hob 7 and/or of theoven 3 and/or of signals coming from the odor sensor. - As stated above, the
oven 3 is also configured to perform a self-cleaning pyrolysis process to perform pyrolytic decomposition to oxidize dirt. - During the pyrolysis process, the temperature in the oven is raised to a pyrolytic temperature of about 350° C. to convert organic material into volatile organic compounds, hydrocarbons and carbonized gas. Carbon monoxide is oxidized into carbon dioxide by the catalyst device and expelled from the
oven 3. - If the pyrolysis process of the
oven 3 is programmed (through the electronic control unit and/or the remote device), the simultaneous activation of thesuction device 100 may be programmed too such that volatile compounds are sucked an expelled from the room/kitchen and/or filtered to eliminate dangerous or undesired substances. - According to the invention, the synchronization of the
range hood 7 with theoven 3 allows to automatically start thesuction device 100 of thehousehold range hood 7 also when the pyrolysis process of theoven 3 is started manually. The manual start is started through a command inputted manually through the electronic control unit and/or theremote device 11. - To this aim, the electronic control unit of the
electrical household system 1 is configured to sense the activation of the pyrolysis process in theoven 3 and to start thesuction device 100 of thehousehold range hood 7 as a function of a communication signal from theoven 3, wherein said signal is correlated to the pyrolysis process in theoven 3. - The invention allows to remove from the room (kitchen) every possible substance deriving from pyrolysis when the pyrolysis is started manually and also in case the catalyst device of the oven does not work properly. This way, safety is greatly improved.
- According to an embodiment of the invention, the
suction device 100 starts as soon as pyrolysis is activated. In other words, the communication signal is emitted together with activation of pyrolysis and this communication signal commands switching on thesuction device 100. There is no substantially delay between the manual activation of the pyrolysis process and the switching on of thesuction device 100. - According to an embodiment, the
suction device 100 starts at a minimum power as soon as pyrolysis is activated. After starting, the power of thesuction device 100 is adjusted as a function of other parameters, such as smoke detection operated through thesmoke detector 500 installed on the household range hood 2 (e.g. the power of thesuction device 100 is increased, with respect to the minimum, when thesmoke detector 500 detects CO and/or CO2). - According to different embodiments of the invention, the start of the
suction device 100 is delayed with respect to the start of the pyrolysis process in theoven 3. Upon receiving the communication signal, emitted together with activation of pyrolysis in theoven 3, the electronic control unit turns on thehousehold range hood 7 in a stand by status but thesuction device 100 is still and does not perform any suction. Thesuction device 100 starts after a time lag with respect to activation of pyrolysis. - According to an embodiment, the
suction device 100 is started when thesmoke detector 500 detects fumes, like CO and/or CO2. - According to an embodiment, the
suction device 100 is started when a temperature in theoven 3 reaches a threshold, i.e. when the temperature sensor in theoven 3 emits a signal. By way of example, the temperature sensor is calibrated to emit the signal when the temperature in theoven 3 reaches a threshold comprised between 150° and 350° C. Preferably, the temperature sensor is calibrated to emit the signal when the temperature in theoven 3reaches 300° C. (maximum cooking temperature) or 350° C. (pyrolysis temperature). - The
electrical household system 1 according to the invention is configured such that signals indicating the status or an event of the other appliances (oven 3 withmicrowave 4, washer/dryer 5,dishwasher 6, kitchen hob 7) are emitted through the output devices of therange hood 7, which are more visible to people in the kitchen. - According to an embodiment, a light signal, such as a blink, or a sound signal is emitted by the output devices of the
range hood 7 at the end of the work cycle of another appliance (such as the dishwasher 6) or when an error occurred. - According to an embodiment, a signal is emitted by the output devices of the
range hood 7 indicating the filter/s and/or the lamp/s of therange hood 7 have to be substituted. These signal status may also be notified through the application (App). - It is an aspect of the present invention to provide a programmable household range hood capable of automatically managing its electrical loads during a time period, usually during a day.
- In particular, it is an aspect of the present invention to provide a household range hood capable of automatically changing its operation mode as a function of time and/or of operations or working status of other appliances.
- It is a further an aspect of the present invention to improve ease of use of a household range hood.
- At least one of the above aspects is substantially achieved by a method of controlling a household range hood which envisages to program operation modes and/or times of said range hood and by a programmable household range hood system.
- In particular, at least one of the above aspects is substantially achieved by a method of controlling a household range hood, by a household range hood system, by an electrical household system and by a particular use of a remote device according to one or more of the appended claims.
- Applicant verified that the possibility of programming the range hood allows to automatically adapt the working status of the electrical loads of said range hood (e.g. of the suction device) as a function of a specific time during day and/or night and/or of operations or working status of other household appliances.
- Applicant verified that the possibility of programming the range hood allows to reduce or at least lower the power consumption of the range hood and/or to adapt the power consumption of the hood as a function of the power consumption of other working appliances in order, e.g., to avoid power overload of the home electrical network.
