Description
The present invention relates to a system for recording physical properties of an item to be cooked or of a cooking process aid according to claim 1. The invention further relates to a range hood for extracting cooking vapors from a cooking area according to claim 10.
The sensor probe is used in particular in connection with household appliances in the preparation of food products to determine various parameters related to the treatment process, in particular the food preparation process. One example of such a sensor probe is a thermometer for measuring the temperature of the contents of a cooking appliance, such as the temperature of the liquid in a cooking pot or the core temperature of a piece of meat or poultry during a preparation process.
While such sensor probe measured data may be used by an operator of the cooking appliance to adjust the settings of the cooking appliance, in more complex cooking appliances, such data may be used directly by the cooktop to automatically adjust the settings of the cooking zone to which the measured data applies.
One such cooking system is described in WO 2012/159865 A1, which discloses a cooking hob, wherein a receiving antenna is provided below the glass surface of the cooking area, which antenna is provided for receiving data transmitted from a temperature probe integrated into or attached to the cooking pot. As can be seen from the variants disclosed in WO 2012/159865 A1 for placing a probe and a receiving antenna, the problems encountered in the cooking system described therein are: in order to provide reliable signal transmission between the probe and the hob, there should be no obstacle between the sensor probe and the receiver, but in a hob with several cooking zones possibly arranged with a plurality of cooking appliances of different shapes and sizes this is difficult to achieve.
In view of the above-mentioned problems in the known cooking systems, it is an object of the present invention to provide a system of the above-mentioned type, allowing a reliable signal transmission between the sensor device and the cooking appliance. According to another object of the invention, a range hood is provided which is designed to support said reliable signal transmission.
According to a first aspect of the invention, this object is solved by a system according to the combination of features of claim 1.
A system for recording physical properties of an item to be cooked or a cooking process aid during a cooking process performed by a cooking appliance, comprising: a sensor device for sensing a physical property of an item to be cooked or a cooking process aid; and first and second transmitting means and first and second receiving means. The first transmitting means are adapted to wirelessly transmit a status signal corresponding to the physical properties of the item to be cooked or the cooking process aid, freely through the space, in particular completely freely through the space. The first emitting means is connected, in particular electrically connected, to the sensor means. The first receiving means is adapted to receive the status signal transmitted by the first transmitting means. The first receiving means are arranged in a separate unit, which is arranged independently of the cooking appliance and/or separately from the cooking appliance. The second transmitting means is electrically connected to the first receiving means and is configured to forward the status signal transmitted by the first transmitting means to the first receiving means or to transmit a processed signal generated by processing the status signal. The second transmitting means is arranged in or at a separate unit. Finally, the second receiving means is adapted to receive the processed signal or the status signal transmitted by the second transmitting means and is arranged in or at the cooking appliance and is electrically connected to the cooking appliance, in particular to a control unit of the cooking appliance.
The cooking appliance is in particular a cooking hob, in particular an induction cooking hob. Of course, the system may comprise other types of cooking hobs, such as an electric radiation hob or a gas hob.
The cooking process aid may be any type of cooker, such as a pan or a pan. Additionally or alternatively, the cooking process aid may be a cooking appliance, like a cooking liquid.
The processed signal may be a control signal for controlling, in particular directly controlling, the cooking appliance. For this purpose, at least one control function of the cooking appliance may be outsourced to a separate unit.
The concepts presented herein are advantageous compared to known solutions in that by providing a separate unit comprising in particular a receiver for receiving the data signal from the sensor device and a transmitter for transmitting the data signal or the processed signal to the cooking appliance, an unobstructed data transmission path can be provided between the sensor device and the receiver at the cooking appliance, the separate unit being located separate from the cooking appliance, preferably at a higher height relative to the cooking appliance, such as at a wall element behind or beside the cooking appliance or at a range hood above the cooking appliance. Such a concept may allow placing the receptacle of the cooking appliance in a position where the cooking appliance (such as a cooker) is not normally placed during operation of the cooking appliance, which may be an edge or corner area of the cooking surface or an area where the control means of the cooking appliance are placed, which area must be left free anyway during operation of the cooking appliance. In this way, signals transmitted from the sensor device to the cooking appliance can freely travel from the device to the separate unit and from the separate unit to the receiver of the cooking appliance, which thus provides a more reliable data transmission than prior art systems.
Preferred embodiments of the system according to the invention are defined in the claims depending on claim 1.
The sensor means may comprise one or more sensors selected from the group consisting of temperature sensors, humidity sensors, impedance sensors, density sensors, pressure sensors or any other type of sensor that may be advantageously used in a cooking environment. Furthermore, the sensor device may comprise different types of sensors, i.e. combinations of the above mentioned sensor types. In a preferred embodiment, the sensor means comprises a temperature sensor. By transmitting the temperature readings to the control means of the cooking appliance, the power level of the respective cooking zone, in particular the cooking zone of the cooking hob in which the temperature readings are obtained, can thus be automatically adjusted to provide a constant predetermined temperature instead of a constant power level.
The second transmitting means and the second receiving means may be wirelessly coupled. Preferably, the second transmitting means and the second receiving means are arranged and/or configured to transmit the status signal or the processed signal through the wireless transmission path and at least partly freely through space.
Particularly preferred embodiments of the sensor device comprise a temperature sensor and/or a piezoelectric Surface Acoustic Wave (SAW) sensor, which allows the sensor to be implemented as a passive sensor unit. In such an embodiment, the sensor device may be designed as a piezoelectric element which emits a Surface Acoustic Wave (SAW) when triggered by a Radio Frequency (RF) interrogation signal, from which the temperature of the sensor device may be determined due to the temperature coefficient of sound velocity. Although the sensor device may be a passive unit, such as a SAW sensor, the sensor device may also be designed as a battery operated device, for example in case the sensor device comprises a display for representing the measured parameter.
In such an embodiment the receiver of the separate unit (i.e. the first receiving means) is configured to receive the surface acoustic waves emitted from the sensor means, whereas the transmitter of the separate unit (i.e. the second transmitting means) may be designed as an infrared transmitter, in which case the receiver at the cooking appliance (i.e. the second receiving means) will correspondingly be designed as an infrared receiver.
To further increase the signal strength, the separate unit may comprise an amplifier for amplifying the signal received from the sensor device.
The cooking appliance may comprise a controller configured to set an operating parameter of the cooking area according to a signal receiver from the sensor device. Thus, for example, if the measured parameter is temperature, the cooking appliance may be operated to adjust the power level of the respective cooking zone so as to provide a constant temperature in the cooking zone or to maintain a certain temperature in the cooking zone for a certain predetermined duration.
According to an embodiment, the first receiving means comprises a signal reader. The signal reader comprises in particular a reader antenna or is coupled or connected to a reader antenna.
In order to provide an unobstructed data transmission between the transmitter of the separate unit and the receiver of the cooking appliance, the receiver at the cooking appliance is preferably located in an area where the cooking appliance is not normally placed during operation of the cooking appliance, such as in a peripheral area of the cooking surface, such as in a boundary area or an edge area.
Another suitable location of the receiver (i.e. the second receiving means) at the cooking appliance is a control area of the cooking appliance in which control means for setting the operating parameters are located, and which area thus usually remains idle or has to remain idle during operation of the cooking appliance.
The separate unit may be a transceiver comprising a receiver for receiving sensor data from the sensor device and a transmitter for transmitting sensor data to the receiver of the cooking appliance. Thus, the individual units may be combined units, wherein the receiver and the transmitter are provided with common circuitry and/or share a common housing.
In a preferred embodiment, the separate unit is configured as a stand-alone unit having a power source such as a mains power source or a battery and which may further have a housing with mounting means for mounting the separate unit in a raised position relative to the cooking appliance. Suitable mounting means may comprise, for example, hook and loop fasteners, adhesive strips or one or more lugs for screws for attaching the mounting means at a wall or kitchen counter behind, beside or on the cooking appliance.
In another preferred embodiment, the system further comprises a range hood located above the cooking appliance, wherein the separate unit is integrated into the range hood. That is, in embodiments where the separate unit is a stand alone unit, it may thus also be mounted to a range hood (such as when the system suggested herein is used with an already existing range hood), whereas in such preferred embodiments the separate unit is integrated into the range hood, i.e. built into the range hood, which allows for the components of the separate unit to be operated by the power supply of the range hood. In particular in the latter embodiment, the system may be further adapted for communication of the hob with a range hood, wherein the range hood is configured to receive control commands from the cooking hob, such as automatically adjusting the operation of the range hood upon a change in control of the cooking area of the cooking hob.
The invention is particularly advantageous in a cooking hob, wherein substantially the entire surface of the cooking surface can be used during operation of the cooking hob, such as in a cooking hob comprising induction heating elements, in particular an induction cooking hob comprising a plurality of heating elements, which heating elements can be combined arbitrarily in order to adapt the size and shape of the cooking zone to be operated to the cooking appliance to be heated in the cooking zone.
According to a second aspect of the invention, this object is solved by a range hood according to the combination of features of claim 10.
A range hood for extracting cooking vapors from a cooking area comprises a first transmitting means and/or a first receiving means and a second transmitting means and/or a second receiving means. The first transmitting means and/or the first receiving means are configured to communicate with, preferably to communicate wirelessly with, a sensor means for sensing a physical property of an item or a cooking process aid to be cooked by the cooking appliance. The second transmitting means and/or the second receiving means are configured to communicate with the cooking appliance, preferably configured to communicate wirelessly with the cooking appliance.
The cooking appliance is for example a cooking hob. Communication between the cooking appliance and the second transmitting device and/or the second receiving device is in particular direct communication. Alternatively, the communication may be performed by an intermediary device or means, for example by a computer means, a server, a router, a smart device, a digital assistant or the internet.
The range hood according to the second aspect of the present invention may be implemented in or included in a system according to any of the preceding embodiments.
The first transmitting means may be adapted to transmit a status signal corresponding to the physical properties of the item to be cooked or the cooking process aid, freely through space, in particular completely freely through space, wirelessly. Additionally or alternatively, the second transmitting means may be adapted to wirelessly forward the status signal or a processed signal generated by processing the status signal at least partly freely through space.
According to a preferred embodiment, the communication between the first transmitting means and/or the first receiving means on the one hand and the sensor means on the other hand is based on bluetooth, RFID or Surface Acoustic Wave (SAW) technology or on free space based optical data transmission, for example infrared data transmission. Additionally or alternatively, the communication between the second transmitting device and/or the second receiving device on the one hand and the cooking appliance on the other hand may be based on bluetooth, WLAN or ZigBee technology or on free space optical data transmission, for example infrared data transmission.
The first receiving means may comprise a signal reader, in particular a signal reader cooperating with a SAW sensor device. The signal reader comprises or is coupled to, in particular, a reader antenna.
More specifically, the sensor device is a temperature probe, in particular a SAW temperature probe, for measuring the temperature of an item to be cooked or of a cooking process aid located in or on a cooking appliance, for example on the cooking hob. The measured temperature is preferably wirelessly transmittable to the first receiving means, more particularly to a signal reader of surface acoustic waves.
Furthermore, a status signal corresponding to a physical property of the item to be cooked or of the cooking process aid may be transmitted to a control unit of the cooking appliance, for example of the cooking hob, which status signal is a processed signal received from the sensor device or generated by processing the status signal. The status signal is in particular a temperature signal received from a temperature probe.
A preferred embodiment of the present invention provides a cooking appliance configured to control and/or modify a power level or a cooking program for an item to be cooked using physical properties. The same or another embodiment features a display device provided for displaying physical properties, such as the temperature of the item to be cooked or the cooking process aid.
A preferred embodiment of the present invention will be described below with reference to the accompanying drawings, which show a schematic view of a cooking system made in accordance with a preferred embodiment of the present invention.
The cooking system shown in the single figure comprises a hob 10 and a range hood 12 located above the hob 10. The hob 10 comprises a glass ceramic cooking surface 14 with a control area 16, wherein below the cooking surface 14 a touch sensitive control element is provided.
In the illustrated embodiment, the cooktop 10 is an induction cooktop that has no specific cooking zone, but wherein a plurality of induction coils are arranged underneath the cooking surface 14, wherein a user may place a cooking appliance, such as a pot 18, anywhere on the cooking surface 14. In such embodiments, the position, shape and size of the cooking appliance may be determined by evaluating the magnetic coupling between the induction coil and the contents of the cooking appliance to be heated.
A sensor probe 20, such as a temperature probe that may include a Surface Acoustic Wave (SAW) sensor, is placed within the pan 18 to measure the temperature within the pan 18, such as the core temperature of a piece of meat within the pan 18 or water contained within the pan 18, and the like. The sensor probe 20 is designed to wirelessly transmit the determined food parameter to a receiver 22 provided on the underside of the range hood 12. An emitter 24, which may be configured as an Infrared (IR) emitter, is disposed on the underside of the range hood 12. Optionally, a signal processing device (such as an amplifier 26) may be provided within the range hood 12 for processing and/or amplifying the signal before it is sent to the cooktop 12 via the transmitter 24.
The cooktop 12 includes a receiver 28, as shown, that may be located within the control area 16 of the cooktop to receive signals transmitted from the range hood. The receiver for receiving the sensor signal may also be arranged in the edge area, such as in a corner of the cooking surface as the receiver 30 shown in the figures.
In the cooking system described herein, measurement data obtained by the sensor probe may be transmitted to the hob, wherein, as the data is sent via the range hood, the signal strength and thus the reliability of the data received at the hob may be significantly improved compared to known systems, as the signal may be transmitted from the sensor probe to the range hood and from the range hood to the hob without being hindered by cooking appliances present at the cooking surface, which would otherwise interfere with or even prevent the data transmission. Furthermore, the signal is transmitted largely wirelessly through free space, and in particular, the signal from the sensor probe 20 to the receiver 22 at the range hood 12 does not need to pass through material (e.g., a solid object) so that attenuation of the signal is avoided.
