ELECTRONIC APPLIANCE AND A SABBATE MODE l ~REFOR
BACKGROUND OF THE INVENTION
Field of the Invention The invention relates to a household appliance, and specifically, to a sabbath mode for a household appliance wherein the appliance can be operated during the Sabbath in compliance with Orthodox Jew custom of no work on the Sabbath.
0 Discussion of the Related Art Overly ~h~lpli~yillg, it is a custom of Orthodox Jews that no work can be done on the Sabbath. The custom forbidswork to be done by the user of a household appliance and Coll~ll ahlS the user from causing the appliance to change its normal pattern of operation, e.g., an action by the user results in the ill~ Al ion of a display, the activation of an audible display 15 or the turning on of a light. Ul~. Lullately, many new household appliances have control systems with a variety of visual and audible indicators and aids, such as interior lights, that make it very difficult, if not impossible, for Orthodox Jews to operate the appliances in compliance with the custom during the Sabbath. For example, most refrigel ~lol ~ and ovens have an interior light that is activated by the user of the appliance by opening the door. Under 20 most inte-~-elalions of the custom, the interior light would satisfy the custom if it always remained on or off, but was not activated by the opening of the door. This has resulted in many Orthodox Jews unscrewing or removing the interior lights of the appliance prior to the Sabbath and replacing after the Sabbath. ~nother example with respect to ovens is that they must be turned offand on to cook. A generally recognized solution is to turn the oven prior 25 to the Sabbath and leave it on until after the Sabbath. Alternatively, the oven could be left off during the Sabbath. Obviously, all the previous solutions are very inconvenient and are a disadvantage of the current appliances.
SUMMARY OF l H~; INVENTION
The invention elimin~tes the disadvantages and inconveniences of the current 30 appliances and their control systems by providing a method and an appliance that can be operated during the Sabbath in accordance with the Orthodox Jewish custom. Generally, all indicators and aids of the appliance that would not comply with the custom during normal operation are fixed in a state that does comply with the custom. Thus, the user is free to continue use of the appliance without fear of not complying with the custom. The control system of the appliance is provided with a sabbath mode that automatically conforms the operation of the appliance with the custom when the sabbath mode is activated.

DESCRIPTION OF TIIE PREFERRED EMBODIMENTS
FIG. 1 illustrates an appliance that can be operated during the Sabbath in conformance with the custom of Orthodox Jews. For illustration purposes, the appliance is an electric range 10. However, it should be noted that the invention is applicable to any appliance and is not limited to an electric range.
The range 10 has a cooktop surface 12 having a plurality of burners 14 and a control panel 15. The control panel 15 provides cooktop control knobs 16 for controlling the burners 14 on the 10 cooktop surface 12. The range 10 also provides an oven cavity 18 for baking and broiling food. The range 10 also has an oven door 20. FIG. 1 shows the range with the oven door 20 in an open position. The open oven door 20 exposes the oven cavity 18 and a heating element 22 therein. The oven cavity has an interior light 25 (FIG.5) which is activated by opening the door 20. A storage drawer 24 is provided beneath the oven cavity 1~. Also shown is a counter top 26. The cooktop surface 12 is flush with the 15 counter top 26.
Another feature of the cooktop surface 12 is an oven vent 28 located near the rear of the cooktop surface 12. Toward the front ofthe cooktop surface 12 is the control panel 15 which further has an electronic oven control 30 for controlling the operation ofthe oven.
FIG. 2 illustrates the electronic oven control 30 ofthe present invention. The control 30 controls the operation of the oven based on user inputs and provides information of the `_ operation to the user via a variety of visual and audible indicators. As shown, the electronic oven control 30 has a multitude of pads and displays thereon to provide a convenient interface for a user when cooking foods using the thermal convection oven. In a pler~.led embodiment, the plurality of pads are melllbl ane switch pads, which allow a clean, flush appearance and s simple use. Also, vacuum fluorescent displays are plèrelled. Beginning in the lower left corner of the electronic oven control 30 and contin~ing in a counter-clockwise direction, a briefdescription ofthe components ofthe electronic oven control 30 will now be described.
The electronic oven control 30 provides oven setting pads 32 for choosing between convection and standard cooking and baking. Also provided are timed and delayed cooking pads 36, an oven light pad 38 and timer pads 40. For convenience, a clock set-start pad 42 is also provided.
In addition, the electronic oven control 30 provides a cancel/offpad 44 and a start pad 46. Also, number pads 48 having digits 0-9 are provided for inputting numerical values for cooking tenlpel aL-Ires and times.
Moreover, the electronic oven control 30 provides a time of day/timer display 50 and an oven display 52. The timer display 50 and the oven display 52 provide valuable i-~--.,alion to the user of the oven. For example, the oven display 52 has visual readouts of several oven-related variables and indicators. For example, a digital start time 54 and digital stop time 56 are provided. Also provided is a check food indicator 58 for instructing a user when to check on the food to see if it is done cooking. A bar graph indicator 60 has a number of segments in a vertical column to graphically display the decrementing time until the oven cavity 18 is at the selected preheat telllpel ~lure. A digital telllp~l al~lre readout 62 provides the user with the temperature of the oven cavity 18. Also, an ON indicator 64 is provided so that the user knows the oven is on. Finally, an oven indicator 66 symbolically shows which elements of the oven cavity 18 are active at a certain time, for example whether convection is operating or standard conventional operation is being used.
Fig. 3 is an enlarged view of the oven display 52 when the control 30 is in the sabbath mode according to the invention. In the sabbath mode, the temperature readout 62 shows the three letters SAb to indicate the sabbath mode. Thus, the user has a visual indication that the oven is operating in the sabbath mode.
The sabbath mode has the advantage of providing the user with a means to operate a household appliance, such as the oven 10, in conformity with the the no work requirement.
2 ! 8 Y 9 1 3 PA-7562-P-RN-USA
The sabbath mode in essence controls the appliance so that no action by the user will be work or will cause the appliance to work patterns. To accomplish this, the sabbath mode places in a fixed state or disables the indicators and aids of the appliance for the duration of the Sabbath. Generally, the sabbath mode will turn off and/or turn on all user actuable indicators or aids, such as audible or visual open door alarms or interior lights, for the duration of the Sabbath. The sabbath mode also makes use of a software controlled door switch delay so that the user's actions on the door will not have immediate effect on software execution. Thus, the user is able to operate the appliance without concern of violating the custom.
Fig. 4 illustrates the first embodiment of the steps for initi~ting and controlling the 0 operation of the sabbath mode. In step 102, the user initiates the sabbath mode. It is presumed for this des~,.ip~ion that the control 30 will permit the initiation ofthe sabbath mode only when a col~palil)le baking or cooking mode is s~lected For example, an llntimed bake mode is s~ti~f~ctory where a timed bake mode is not because the timed bake automatically turns the oven offand would require the user to restart the oven m~ml~lly during the Sabbath.
Preferably, the sabbath mode is initi~ted by depres~.ing one of the keys on the numeric keypad for a predete.. ned amount of time to ensure that the user does wish to initiate the sabbath mode. In the prer~lled embodiment, the user will depress the "6" key on the numeric key pad for five seconds to initiate the sabbath mode. However, it should be evident to one skilled in the art that the sabbath mode could be activated in a variety of ways, incl~lding the 20 addition of a sabbath mode key on the control 30. For example, if the control 30 had a calendar, the sabbath mode could be activated automatically at the appropriate time of the week.
Once the sabbath mode is activated, the temperature display displays the letters SAb as is shown in step 104. In step 106 all audible signals are disabled for the duration of the 25 sabbath mode. Similarly, step 108 disables all unnecess~y displays, such as, for example, timer 50, start and stop times 54, 56, check food indicator 58, bar graph 60. However, the ON indicator 64 and oven inrlic~tor 66 are not disabled in the prere..ed embodiment.
Step 110 fixes the status ofthe oven light and any other relevant lights. That is, if the oven light was on when the sabbath mode is initi~te~, the light will remain on until the end of 30 the sabbath mode. Likewise, if the light is off, it remains off for the duration of the sabbath mode. Typically, this is accomplished by disabling the oven light pad 38 and preventing the opening of the door 20 from activating the light. Alternatively, it is possible to permit the user to select the light as either offor on before or as part of the setup for the sabbath mode.
In step 112, the variable parameters of the sabbath mode, such as oven light on or off, along with an indication that the sabbath mode was set are stored in the nonvolatile memory 132 (Fig.5) ofthe Gontrol 30. Thus, if there is a power failure during the sabbath mode, the appliance will restart in the sabbath mode with the same settings when power is restored.
The keypad 48 is reprog,~m"~ed so that each ofthe keys represents a di~re.l~
temperature in step 114. Preferably, the keys are reprogrammed according to Table 1. It should be noted that the keypad can be reprogrammed for any set of temperatures as desired.
Table Key Definitio -o 450F
By reprogr~ " ~ g the keypad, the user is able to select a variety of temperatures at which the oven can operate without using a display or causing a display to change according to the user's selection. In step 116, all the unused or unneeded pads of the control are disabled so 15 that the user cannot accidentally activate any of the pads and cause the m~chine to enter a di~eren~ mode during the duration of the sabbath mode.
In step 118, the heating element 22 is polled to determine if the element is currently on.
If it is, the element indicator 66 (curved lines) is illllmin~ted The user of the appliance is free to open the door when the element indicator is ill~min~ted so that that user's opening of the door will not "turn on" the element 22. It is plerelled that the element indicator 66 pulse for a predetermined time period, applo~ alely five seconds, prior to a change is status ofthe heating element 22 (or broiler element in some instances) to give the user warning of a pending change. Alternatively, the ON indicator 64 could pulse prior to a status change in the heating element.
erel~bly, the status of the element indicator 66 is fixed if the user opens the oven 0 door 24 so that the user's action of opening the door does not change the elem~ntindicator, which would be considered work. The control 30 would delay the status change of the element indicator 66 for a predetermined amount oftime, appro~,lllately 30 seconds, after the door is closed. Similarly, if the heating element 22 is on when the door is opened, it will be turned off apploxilllalely five seconds after opening and will not be turned on until approximalely 30 seconds after the door is closed.
In step 120, the sabbath mode is termin~ted by the user. Preferably, in the samemanner by which the sabbath mode was initi~ted by depressing the "6" key for five seconds.
As stated above, there are many ways to turn on such a mode and, likewise, there are many ways to turn off such a mode.
FIG. 5 illustrates a functional block diagram of the elements of an oven having a sabbath mode accord;.lg to the invention. As illustrated, an oven control system 130 is the heart ofthe invention. The control system 130 is connected to non-volatile memory 132 in which the sabbath mode parameters are stored. The oven control 30 is connected to the control system 130 and sends and receives input and output from and to the oven control 30.
Thus, the control system can control the operation of the displays and pads of the oven control 30. The control system 130 is also connected to several other components ofthe oven. The oven light 134 is connected to the control system so that the controller can control the operation ofthe light. Also, the heating element is connected to the control system 130. In addition, the oven door is connected to the control system 130. Thus, the control system can monitor the status of all the components of the oven to ensure that the oven is operated in accordance with the no work custom.
2189~13 `_ Although the present invention has been described with reference to a specific embodiment, those of skill in the Art will recognize that changes may be made thereto without departing from the scope and spirit of the invention as set forth in the appended claims.

The sabbath mode in essence controls the appliance so that no action by the user will be work or will cause the appliance to work patterns. To accomplish this, the sabbath mode places in a fixed state or disables the indicators and aids of the appliance for the duration of the Sabbath. Generally, the sabbath mode will turn off and/or turn on all user actuable indicators or aids, such as audible or visual open door alarms or interior lights, for the duration of the Sabbath. The sabbath mode also makes use of a software controlled door switch delay so that the user's actions on the door will not have immediate effect on software execution. Thus, the user is able to operate the appliance without concern of violating the custom.
Fig. 4 illustrates the first embodiment of the steps for initi~ting and controlling the 0 operation of the sabbath mode. In step 102, the user initiates the sabbath mode. It is presumed for this des~,.ip~ion that the control 30 will permit the initiation ofthe sabbath mode only when a col~palil)le baking or cooking mode is s~lected For example, an llntimed bake mode is s~ti~f~ctory where a timed bake mode is not because the timed bake automatically turns the oven offand would require the user to restart the oven m~ml~lly during the Sabbath.

For example, if the control 30 had a calendar, the sabbath mode could be activated automatically at the appropriate time of the week.
Once the sabbath mode is activated, the temperature display displays the letters SAb as is shown in step 104. In step 106 all audible signals are disabled for the duration of the 25 sabbath mode. Similarly, step 108 disables all unnecess~y displays, such as, for example, timer 50, start and stop times 54, 56, check food indicator 58, bar graph 60. However, the ON indicator 64 and oven inrlic~tor 66 are not disabled in the prere..ed embodiment.
Step 110 fixes the status ofthe oven light and any other relevant lights. That is, if the oven light was on when the sabbath mode is initi~te~, the light will remain on until the end of 30 the sabbath mode. Likewise, if the light is off, it remains off for the duration of the sabbath mode. Typically, this is accomplished by disabling the oven light pad 38 and preventing the opening of the door 20 from activating the light. Alternatively, it is possible to permit the user to select the light as either offor on before or as part of the setup for the sabbath mode.
In step 112, the variable parameters of the sabbath mode, such as oven light on or off, along with an indication that the sabbath mode was set are stored in the nonvolatile memory 132 (Fig.5) ofthe Gontrol 30. Thus, if there is a power failure during the sabbath mode, the appliance will restart in the sabbath mode with the same settings when power is restored.
The keypad 48 is reprog,~m"~ed so that each ofthe keys represents a di~re.l~
temperature in step 114. Preferably, the keys are reprogrammed according to Table 1. It should be noted that the keypad can be reprogrammed for any set of temperatures as desired.

By reprogr~ " ~ g the keypad, the user is able to select a variety of temperatures at which the oven can operate without using a display or causing a display to change according to the user's selection. In step 116, all the unused or unneeded pads of the control are disabled so 15 that the user cannot accidentally activate any of the pads and cause the m~chine to enter a di~eren~ mode during the duration of the sabbath mode.
In step 118, the heating element 22 is polled to determine if the element is currently on.
If it is, the element indicator 66 (curved lines) is illllmin~ted The user of the appliance is free to open the door when the element indicator is ill~min~ted so that that user's opening of the door will not "turn on" the element 22.

Alternatively, the ON indicator 64 could pulse prior to a status change in the heating element.
erel~bly, the status of the element indicator 66 is fixed if the user opens the oven 0 door 24 so that the user's action of opening the door does not change the elem~ntindicator, which would be considered work. The control 30 would delay the status change of the element indicator 66 for a predetermined amount oftime, appro~,lllately 30 seconds, after the door is closed. Similarly, if the heating element 22 is on when the door is opened, it will be turned off apploxilllalely five seconds after opening and will not be turned on until approximalely 30 seconds after the door is closed.
In step 120, the sabbath mode is termin~ted by the user. Preferably, in the samemanner by which the sabbath mode was initi~ted by depressing the "6" key for five seconds.
As stated above, there are many ways to turn on such a mode and, likewise, there are many ways to turn off such a mode.
FIG. 5 illustrates a functional block diagram of the elements of an oven having a sabbath mode accord;.lg to the invention. As illustrated, an oven control system 130 is the heart ofthe invention. The control system 130 is connected to non-volatile memory 132 in which the sabbath mode parameters are stored. The oven control 30 is connected to the control system 130 and sends and receives input and output from and to the oven control 30.
Thus, the control system can control the operation of the displays and pads of the oven control 30. The control system 130 is also connected to several other components ofthe oven.
