Advantages of the present disclosure will become more apparent to those skilled in the art from the following description of the preferred embodiments of the invention that have been shown and described by way of illustration. As will be realized, the disclosure is capable of other and different embodiments, and its details are capable of modification in various respects. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.
Referring now to the embodiments shown in
The oven 10 includes a housing 20 that defines a cooking chamber 22, one or more doors 24 that are openable to allow access to the cooking chamber 22 and closable to selectively isolate the cooking chamber 22, and a heat source 26 disposed within the cooking chamber 22 to apply heat to a food product disposed within the cooking chamber 22. The heat source 26 may be one or more electric resistance heaters, one or more gas combustion heaters, or other types of heat sources suitable for an oven that are known in the art. The housing 20 may additionally include one or more racks 28 or similar structural members to support and align food products within the cooking chamber 22 to receive heat from the heat source 26.
The oven 10 additionally includes one or more sensors 40 disposed proximate to or within the cooking chamber 22. The sensors 40 may be configured monitor a selected parameter related to cooking a food product within the cooking chamber 22 and transmit data that relates to or is proportional to the sensed parameter. By way of example, the sensor 40 may be a temperature sensor that monitors the ambient temperature within the cooking chamber 22, a temperature sensor that monitors a surface or internal temperature of a food product, a moisture or humidity sensor disposed within the cooking chamber 22, or one of a plurality of other types of sensors that are usable with and are related to the process of cooking a food product within an oven 10.
The sensor 40 is configured to communicate data with a microprocessor 60 (discussed below) that is disposed in conjunction with the oven 10. The sensor 40 may provide data by way of a sensor signal X that relates to the parameter being monitored by the sensor 40. In some embodiments, the sensor 40 may provide a sensor signal X that is proportional to a monitored parameter. In other embodiments, the sensor 40 may selectively send the sensor signal X when the monitored parameter is within a predefined range or threshold, or when the monitored parameter is equal to, above, or below a predefined setpoint.
The sensor 40 may be connected to a power source to provide electrical current to provide power to the sensor 40 and to allow the sensor 40 to provide data by way of a sensed signal X that relates to the monitored parameter. The sensor 40 may receive AC or DC current from a microprocessor 60 that the sensor 40 is electrically connected therewith, or the sensor 40 may receive electrical current from a dedicated battery in communication with the sensor 40. The sensor 40 communicates with the microprocessor 60 either with a direct electrical connection or with an indirect connection that enables the sensor 40 to communicate with the microprocessor 60. For example, the sensor 40 may communicate with the microprocessor 60 via a wireless signal, which may be infrared, RF, or other types of signals known in the art.
The microprocessor 60 includes one or more inputs that receive one or more sensed signals X, X′ and data from one or more sensors 40 disposed within, proximate to, or in conjunction with the cooking chamber 22 or the housing 20 of the oven 10. The microprocessor 60 additionally includes a memory that may include RAM, ROM, or a combination of the two, or one or more electromechanical memory devices that enable the microprocessor 60 to receive signals related to the operation of the oven 10 and transmit operational signals to the heat source 26 or other components of the oven 10 to control the operation of the oven 10 as programmed during manufacture of the oven 10 and/or as desired by the user.
The microprocessor 60 additionally includes a transmitter 80 that may receive data, for example a sensed signal X, directly from one or more sensors 40 or alternatively, receive data from the microprocessor 60 that is representative of or related to the data received by the microprocessor 60 from one or more sensors 40. The data may be a sensed signal X. The data received by the transmitter 80 is representative of the parameter sensed by the sensor 40, and may be proportional to the parameter, or otherwise related to the parameter, such as a high or low signal based on the value of the parameter when compared to a reference value stored in the microprocessor. Each of the schematic block diagrams of
Upon receipt of the data from the microprocessor 60 (or directly from one or more sensors 40 by way of a sensed signal X) the transmitter 80 emits a wireless signal that relates to the data received by the transmitter 80. The wireless signal may be proportional to the data, or otherwise related to the data. By way of example, the wireless signal may be an analog or digital signal that is proportional to the data and ultimately the parameter measured by the sensor 40. Alternatively, the wireless signal may be a high signal when the measured parameter is a predetermined value, above or below a predetermined value, within a range of values, and a low signal (or in some embodiments no signal is transmitted by the transmitter 80) when the parameter measured by the sensor 40 is not the reference value, selectively above or below a reference value, or not within a range of values.

In still further embodiments as shown in
The wireless signal may be an infrared signal, an RF signal, or another type of wireless signal known in the art. The wireless signal is configured to be received and deciphered by a receiver 100 (discussed below). In some embodiments, the wireless signals (i.e. the address and data signals Y, Z) may operate within any regulated or unregulated band that is configured to allow for reliable communication from the transmitter 80 to the receiver 100 without significant interference with or from other ambient signals that may be sensed by the receiver 100. In some embodiments, the transmitter 80 and the receiver 100 may be configured to operate on an unlicensed Industrial, Scientific, and Medical (ISM) band, such as between 2.4-2.483 GHz.
As shown in
The transmitter 80 or the microprocessor 60 includes a memory 62 (shown schematically as a part of the microprocessor 60 in
As shown in
In some embodiments, the display 110 of the receiver 100 activates (i.e. provides an indication from the display 110) at any time that a signal (whether address Y or Z) is received from the transmitter 80. In other embodiments, the display 110 only activates when an address signal Y is received by the receiver 100 that corresponds to a receiver code saved by the address memory 106, as discussed below.
The receiver 100 includes a display 110 that provides an indication that is observable by the user. The indication may be visual, audible, tactile, or vibrational and is representative of the value of the parameter sensed by the sensor 40. In some embodiments, the display 110 may have an ON state and an OFF state, which are each selectively provided depending on the receipt of an address signal Y that corresponds to the code stored within the address memory 106. For example, in some embodiments, the display 110 of the receiver 100 is configured to display the ON state when the receiver 100 receives an address signal Y that is representative of the code stored in the address memory 106 of the receiver 100. When the receiver 100 receives other signals, the display 110 remains in the OFF state. The receiver 100 may include a comparator circuit 109 that compares the value of the address signal Y with the code stored in the address memory 106 of the receiver 100.
When the display is in the ON state, the display 110 may emit a light, a noise, a vibration, or other tactile signal. When the display 110 is in the OFF state (i.e. when an address signal Y that corresponds to the code retained in the address memory 106 is not received), the display 110 does not emit a light, noise, vibration or any other discrete signal. As can be understood, the display 110 is in the ON state when the parameter monitored by the sensor 40 is within a specific range, or above or below a specific state as determined by the microprocessor 60.
In some embodiments, the receiver 100 is configured to selectively provide an indication on the display 110 whenever the address signal Y matches the code within the address memory 106 or whenever any address signal Y is received when the address memory 106 is adjusted to a universal code. For example, in some embodiments the address memory 106 may be multiple binary electromechanical switches, such as DIP switches, for example as four DIP switches. In this embodiment, the address memory 106 includes 16 possible codes depending on the position of each of the DIP switches. If the code is adjusted to a predetermined universal code, such as the binary zero value (i.e. all switches to the low position, 0000) the display 110 may be on the ON state whenever any address signal Y is received, which may be useful for testing the communication between the transmitter 80 and the receiver 100. If the code is adjusted to the binary fifteen position (i.e. all switches in the high position, 1111), the display 110 may be on the OFF state regardless of the type or existence of the address signal Y. Further, when code is adjusted to one of the remaining fourteen binary values (i.e. 0001, 0110, etc.) the display 110 is in the ON state whenever the address signal Y corresponds to the code retained within the address memory 106. The receiver 100 may additionally have an ON/OFF switch that selectively allows electrical power flow from the batteries to the display 110 and other circuitry of the receiver 100.
In other embodiments the receiver 100 is configured to selectively display the value of the data signal Z, which may be proportional to the parameter monitored by the sensor 40. In this embodiment, the receiver 100 is configured to receive and process both the address signal Y and the data signal Z (i.e. interpret the address and/or data signals Y, Z and demodulate the signals Y, Z, if necessary). In some embodiments, the receiver 100 constantly receives the address signal Y and compares the address signal Y to the code stored within the address memory 106 with a comparator circuit 109. When the address signal Y matches the code within the address memory 106, the receiver 100 then processes the data signal Z emitted from the transmitter 80. Specifically, the display 110 provides an output that is proportional to the value of the data signal Z, which is ultimately proportional to the value of the parameter measured by the sensor 40 within or proximate the cooking compartment 20. In embodiments where the display 110 provides a visual output, the output may be through a digital or an analog display (i.e. a numerical readout, an analog gauge or meter (
In some embodiments as shown in
In some embodiments, the transmitter 80 may initially emit an address signal Y that is representative of the transmitter code when the transmitter 80 is energized. If receiver 100 is also energized and configured to receive the same address signal (i.e. the receiver 100 is not currently in acknowledge mode or snooze mode as discussed above), the receiver 100 display 110 provides an indication that the transmitter 80 and receiver 100 are properly communicating.
In some embodiments, a plurality of sensors 40, 40′ may be disposed within or proximate the cooking compartment 20 and provide data (such as sensed signals X, X′) to the microprocessor 60 that relates to the value of each sensed parameter. The microprocessor 60 includes a plurality of stored reference values and a comparator 69 that compares the data with the reference values to generate a plurality of address signals Y, Y′ and/or the data signals Z, Z′ when the comparator 69 notes a favorable comparison between the sensed signals X, X′ (or other types of data) from the sensor 40, 40′ and the reference values. The microprocessor 60 may assign the data from each specific monitored parameter (by way of sensed signals X, X′) a different address signal Y, Y′, which corresponds to the specific receiver 100, 100′ that is configured to monitor and provide a display related to the sensed parameter.
In still other embodiments shown in
In operation, an oven 10 selectively receives a heat input from the heat source 26 disposed within the cooking compartment 20. One or more sensors 40 are disposed within or proximate the cooking compartment 20 and are configured to provide data, such as a sensed signal X, that is representative of the parameter measured by the sensor 40. The one or more sensors 40 communicate with a microprocessor 60 that is provided with the oven 10. The microprocessor 60 includes a comparator 69 that compares the value of the sensed signal X with a reference value or range stored within the memory 62 of the microprocessor 60. The microprocessor 60 communicates with the transmitter 80 depending on the comparison between the sensed signal X and the reference value. In some embodiments, the microprocessor 60 only communicates with the transmitter 80 when the sensed signal X is favorably compared with reference value or range (i.e. the sensed signal X is within a specified range or selectively equal to, above, or below a specified level). In other embodiments, the microprocessor 60 communicates with the transmitter 80 with a signal proportional to the value or state of the parameter monitored by the sensor 40, but also provides a second signal that is based on the output of the comparator circuit 69.
The transmitter 80 receives the output of the microprocessor 60, as discussed above, and selectively emits one or more signals that are representative of the monitored parameter. In a first embodiment, the transmitter 80 emits an address signal Y when the microprocessor 60 sends a signal based upon a favorable comparison with the reference value, and does not emit any signal when a favorable comparison signal is not received. The address signal Y is representative of the transmitter code, which is programmed into one of the microprocessor 60 or the transmitter 80. The transmitter code is the same as the code stored within the address memory 106 of the receiver 100 to ensure proper communication from the transmitter 80 to the receiver 100. The receiver 100 is configured to provide the remote indication related to the monitored parameter based on the receipt of a correct address signal Y. In other embodiments, the transmitter 80 constantly emits an address signal Y (representative of the transmitter code) to the receiver 100 and a data signal Z that is representative of the value of the monitored parameter. In some embodiments the microprocessor 60 may receive sensed signals X, X′ from various different sensors 40, 40′, perform comparison steps with respect to the sensed signals X, X′ from each sensor 40, 40′, and communicate with the transmitter 80 regarding the value of each monitored parameter.
A receiver 100 is provided and is operable in a remote location from the transmitter 80. The receiver 100 is configured to search for an emitted address signal Y that corresponds to the code programmed into the address memory 106 of the receiver 100. In some embodiments, the display 110 of the receiver 100 provides an ON signal (or other type of display discussed herein) whenever the address signal Y corresponding to the code is received by the receiver 100. In other embodiments, the receiver 100 provides an output from the display 110 that is representative of the sensed parameter (based on the value of the data signal Z received by the receiver) whenever an address signal Y received by the receiver 100 matches the code stored in the address memory 106.
