Definitions
- the present disclosure relates generally to small appliances, and more particularly to toaster ovens.
- a toaster oven is a small appliance that functions as both a toaster and an oven.
- a toaster oven often has a control knob that controls the duration of operation of the toaster oven.
- a conventional toaster oven control panel 10 is illustrated in FIG. 1 .
- the illustrated control panel 10 has three control knobs.
- Control knob 12 controls the temperature during operation of the toaster oven.
- Control knob 14 modifies operation of the appliance depending on which function is to be performed (e.g., toast, bake, broil, etc.).
- Control knob 16 controls the duration of operation of the toaster oven.
- the control knob 16 can either activate the toaster oven for a desired number of minutes or activate the toaster oven until the user turns the toaster oven off This latter feature is typically termed the “stay on” feature.
- the toaster oven is deactivated when the control knob 16 is facing the “off” setting (i.e., the 9:00 clock position on the illustrated control panel 10 , although this may vary).
- the control knob 16 is turned clockwise to the number 18 indicative of the desired duration (in minutes) of operation of the toaster oven.
- the control knob 16 can be coupled to a mechanical timer (not illustrated) so turning the control knob 16 clockwise to the desired number activates the timer and therefore the operation of the toaster oven for the set number of minutes.
- the user turns the control knob 16 counterclockwise to the “stay on” setting 20 .
- the toaster oven will then remain activated until the user turns the control knob 16 back to the “off” setting.
- a spring or other biasing force moves the timer knob baco to the “off” setting as the timer counts down. If the dial were to move past the “off” position into the “stay on” position, either through mechanical failure or user error, there is a possibility, in very limited instances, for the toaster oven to remain energized indefinitely without any deliberate action by the user. This is a potential risk if there is combustible material in the oven.
- the toaster oven control knob of the following disclosure accomplishes the above and other objectives and overcomes at least the above-described disadvantages of conventional toaster ovens.
- the toaster oven comprises a housing defining a food cavity, an opening defined in the housing to enable access to the food cavity, a door movably affixed to the housing and selectively movable between a closed position closing off the opening thereby blocking access to the food cavity and an open position enabling access to the food cavity, a cooking grid selectively mountable within the housing, one or more heating elements within the housing, a timer controlling activation of the heating elements, and a timer control knob engaged with the timer.
- the timer control knob is selectively rotatable in a first direction from an off position to a second position to set the timer and activate at least one of the one or more heating elements for a desired amount of time corresponding to the second position.
- the timer control knob is selectively rotatable in a second direction from the off position to a third position to activate at least one of the one or more heating elements until the timer control knob is selectively rotated in the first direction back to the off position, the second direction being opposite the first direction.
- the timer control knob has a selectively depressible pushbutton, and the timer control knob is only selectively rotatable in the second direction from the off position to the third position when the pushbutton is depressed.
- the stationary block may project outward from the housing.
- the timer control knob may comprise a lock lever engaged with the pushbutton such that depressing the pushbutton moves the lock lever from a first position to a second position. In the first position, the lock lever is aligned with the stationary block to prevent rotation of the timer control knob in the second direction from the off position to the third position. In the second position, the lock lever is not aligned with the stationary block to permit rotation of the timer control knob in the second direction from the off position to the third position.
- the lock lever may be biased to the first position.
- the lock lever may pivot from the first position to the second position.
- the lock lever may have an angled surface that engages with the stationary block as the timer control knob is rotated from the third position in the first direction. Such engagement pushes the lock lever from the first position to the second position to permit rotation of the timer control knob in the first direction back to the off position without depressing the pushbutton.
- the lock lever may have a planar leading edge that is substantially perpendicular to a corresponding engaging edge of the stationary block.
- the selectively depressible pushbutton may be a first selectively depressible pushbutton.
- the timer control knob may have a second selectively depressible pushbutton opposite the first selectively depressible pushbutton.
- the timer control knob may comprise a dummy lock lever engaged with the second pushbutton such that depressing the pushbutton moves the lock lever from a first position to a second position.
- the dummy lock lever may not engage the stationary block in the first position or in the second position.
- FIG. 1 is a front view of a conventional toaster oven control panel.
- FIG. 2 is a perspective view of a toaster oven control knob, according to one embodiment of the present disclosure.
- FIG. 3 is a cross-sectional view of the toaster oven control knob of FIG. 2 .
- FIG. 4 is a partial front view of a toaster oven for use with the toaster oven control knob of FIG. 2 , but with the toaster oven control knob removed.
- FIG. 5 is a perspective view of components of the toaster oven control knob of FIG. 2 .
- FIGS. 2-5 illustrate a toaster oven control knob 30 in accordance with a preferred embodiment of the present disclosure.
- Control knob 30 and associated stationary block 60 provide a simple and cost-effective means for adding a secondary action to engage the stay-on feature in a toaster oven with a clock-operated switch having a stay-on feature which is activated in the same direction as the countdown to “off.”
- Control knob 30 may be incorporated into any suitable toaster oven or other similar cooking appliance.
- control knob 30 is selectively rotatable clockwise and counterclockwise to either activate a toaster oven for a desired number of minutes or to activate the toaster oven until it is turned off (“stay on”).
- the toaster oven is deactivated when the control knob 30 is facing the “off” setting (i.e., the 12:00 clock position on the illustrated legend).
- the control knob 30 is turned clockwise to the number 52 indicative of the desired duration (in minutes) of operation of the toaster oven.
- the control knob 30 To activate the toaster oven until it is turned off (“stay on”), the user turns the control knob 30 counterclockwise to the “stay on” setting 54 . The toaster oven will then remain activated until the user turns the control knob 30 counterclockwise back to the “off” setting.
- the control knob 30 may be coupled to a mechanical timer (not illustrated).
- a stem 36 extends from the rear side of the control knob 30 , such that the stem 36 protrudes through a hole 64 defined in the face of the toaster oven 56 (partially illustrated in FIG. 5 ) when the control knob 30 is mounted to the toaster oven.
- a cavity 38 defined in the stem 36 engages a corresponding post of the mechanical timer (not illustrated), so turning the control knob 30 turns the post of the mechanical timer.
- the main body 32 of the control knob 30 may be generally bell-shaped, with an open rear side and hollow interior such that an internal chamber 34 is defined therein.
- the stem 36 extends out of this chamber 34 .
- the control knob 30 of embodiments of the present disclosure includes at least a first button 40 and optionally a second button 42 .
- the first button 40 may be positioned on an exterior side of the control knob 30 , such that the first button 40 is readily depressed by a user as needed (as described further below).
- the second button 42 may be positioned on an exterior side of the control knob 30 opposite the first button, such that both buttons are readily depressed simultaneously by a user as needed.
- the first button 40 is affixed to or integral with a lock lever 44 that extends toward the open rear side, as illustrated in FIG. 3 .
- the lock lever 44 extends close enough to the opening at the rear side of the control knob to engage the stationary block (as described further below) but does not extend past the opening (which would cause the lock lever 44 to undesirably contact the face of the toaster oven).
- the first button 40 and lock lever 44 are biased outward, such as with bias spring 48 .
- the second button may or may not be affixed to or integral with a lever 46 that may extend toward the open rear side, as illustrated in FIG. 3 .
- the lever 46 if it exists, should not extend close enough to the opening at the rear side of the control knob to engage the stationary block at any point during the rotation of the control knob 30 .
- the second button 42 and lever 46 are biased outward, such as with bias spring 48 .
- a stationary block 60 protrudes outward from the face of the toaster oven 56 .
- the stationary block is positioned such that the main body 32 of the control knob 30 covers the stationary block (i.e., most or all of the stationary block is within the chamber 34 ) when the control knob 30 is mounted to the toaster oven.
- the stationary block 60 may comprise a thin planar projection.
- the stationary block 60 of FIG. 4 is stamped, cut, or otherwise formed from the face of the toaster oven as a tab that is folded out such that it is substantially perpendicular to the face of the toaster oven.
- the stationary block 60 and lock lever 44 are positioned such that, when the control knob 30 is in place on the toaster oven and in the “off” setting, the lock lever 44 is adjacent the stationary block 60 .
- the distal end of the lock lever 44 would contact and be blocked by the stationary block 60 when a user attempts to turn the control knob 30 from the “off” position (counterclockwise in the illustrated embodiment) to the “stay on” position, thus preventing rotation of the control knob 30 from the “off” position to the “stay on” position (unless, as described below, the first button 40 is depressed to move the lock lever 44 ).
- the leading edge 58 of the distal end of the lock lever 44 may be squared off (planar), as seen in FIG. 5 , to ensure good contact between the lock lever 44 and the stationary block 60 to block the rotation of the control knob from the “off” position (counterclockwise in the illustrated embodiment) to the “stay on” position.
- the user In order for a user to be able to turn the control knob 30 from the “off” position (counterclockwise in the illustrated embodiment) to the “stay on” position, the user must depress the first button 40 (the user may also depress the second button 42 , if present, but that may or may not be necessary). Depressing the first button 40 causes the lock lever 44 to move inward (for example, by a sliding or pivoting motion, or any other suitable motion or mechanism). This inward movement of the lock lever 44 allows the distal end of the lock lever 44 to clear the stationary block 60 , thereby enabling the control knob 30 to be rotated (counterclockwise in the illustrated embodiment) from the “off” position to the “stay on” position. Once the distal end of the lock lever 44 has rotated past the stationary block 60 and the user releases the first button 40 , the first button and the lock lever 44 will move outward and return to their original positions due to the outward biasing.
- FIG. 5 illustrates the buttons, lock levers, and bias springs of control knob 30 , removed from the control knob.
- the first button 40 is integral with or affixed to lock lever 44
- the second button 42 is integral with or affixed to lock lever 46 .
- depressing the first button 40 causes the lock lever 44 to move inward
- depressing the second button 42 causes the lock lever 46 to move inward.
- the lock levers pivot inward when the corresponding button is depressed.
- Each lock lever comprises pivot arms 66 that engage the inside top surface of the knob to enable the distal ends (i.e., the ends closer to the face of the toaster oven) to pivot inward.
- lock lever 44 i.e., the lock lever which engages the stationary block
- lock lever 44 may have an angled surface 50 that engages with the stationary block as the control knob 30 is rotated from the “stay on” setting to the “off” setting.
- the stationary block 60 comprises a thin metal tab.
- the stationary block may be thicker. If the stationary block is thicker, it may be desirable for the stationary block to have an angled surface that engages with the angled surface of the lock lever as the control knob 30 is rotated from the “stay on” setting to the “off” setting. Having angled surfaces on both the lock lever and the stationary block may better facilitate the desired inward forcing of the lock lever to permit rotation of the control knob back to the “off” setting without having to depress the first button.
- the stationary block may be any suitable height that provides the desired blocking of the counterclockwise rotation from the “off” position to the “stay on” position (except when the first button or a similar mechanism is depressed), but which does not otherwise interfere with the operation or rotation of the control knob.
- the lock lever and/or stationary block may be sized and/or positioned such that the lock lever and the stationary block remain in contact, and the lock lever remains pushed inward, when the control knob is in the “stay on” position.
