On traditional control handle, control handle 30 can be connected to mechanical timer (not shown).Bar 36 is from control
The rear side of knob 30 stretches out so that when control handle 30 is installed to baking box, bar 36, which projects through, is limited to baking box 56 (in Fig. 5
In partly show) surface in hole 64.The post (not shown) corresponding to mechanical timer of cavity 38 being limited in bar 36
Engagement, therefore rotary control knob 30 causes the post rotation of mechanical timer.
The main body 32 of control handle 30 can generally be bell, have open back side and hollow inside so that wherein
Define internal chamber 34.Bar 36 is extended to outside this chamber 34.
Different from Traditional control knob, the control handle 30 of embodiment of the present disclosure comprises at least the first button 40 and can
Second button 42 of choosing.First button 40 can be positioned on the outside of control handle 30 so that the first button 40 is by user
Readily easily press (as described further below).If there is the second button 42, then the second button 42 can be with
First button is oppositely located on the outside of control handle 30 so that user readily easily press simultaneously by pressing two

It is biased outwardly by biasing spring 48.
Fixed block 60 is outstanding from the surface of baking box 56.Fixed block is located so that when control handle 30 is installed to baking box
When control handle 30 main body 32 cover fixed block (that is, most or all of fixed block is located in chamber 34).In Fig. 4
Shown, fixed block 60 can include thin flat protuberance.Fig. 4 fixed block 60 from the surface punching press of baking box, cutting or with
Other modes are formed as the lug folded so that it is substantially vertical with the surface of baking box.
Fixed block 60 is positioned so as to securing rod 44, when control handle 30 is located at the appropriate location on baking box and is in
When " closing " is set, securing rod 44 is adjacent to fixed block 60.In this respect, when user is attempted control handle 30 from " closing " position
When putting rotation (counterclockwise in the embodiment as shown) to " staying open " position, the distal end of securing rod 44 will contact and be consolidated
Determine block 60 to stop, thus prevent control handle 30 from rotating to " staying open " position (unless as described herein below from " closing " position
, the first button 40 is pressed to move securing rod 44).As finding, the leading edge 58 of the distal end of securing rod 44 can be done in Figure 5
Squarely (plane), to ensure the good contact between securing rod 44 and fixed block 60, so as to stop control handle from " closing "
Position rotates (counterclockwise in the embodiment as shown) to " staying open " position.
In order to which control handle 30 can be rotated (counterclockwise in the embodiment as shown) by user from " closing " position
To " staying open " position, user must press the first button 40 (user can also press the second button 42 (if there is
If), but this may or may not be necessary).Press the first button 40 cause securing rod 44 move inward (for example,
By sliding or moving pivotally, or any other appropriate motion or mechanism).This move inward of securing rod 44 allows to lock
Thus the distal end of fixed pole 44 enables control handle 30 be rotated from " closing " position (in the embodiment party shown away from fixed block 60
In formula counterclockwise) to " staying open " position.Once the distal end rotation of securing rod 44 discharges by fixed block 60 and user
First button 40, the first button will be displaced outwardly with securing rod 44 due to outwards biasing and return to their original locations.
Fig. 5 shows the button, securing rod and the biasing spring that are removed from control handle of control handle 30.Such as in Fig. 4
In see, the first button 40 is with the one of securing rod 44 or fixed to securing rod 44, and the second button and securing rod 46 1

42 cause securing rod 46 to move inward.In the embodiment as shown, when pressing corresponding button, securing rod inwardly pivots.
Each securing rod includes pivotal arm 66, and pivotal arm engages with the inside top surface of knob, so that distal end is (that is, closer to baking box
Surface end) can inwardly pivot.
When user it is expected to close baking box (from " staying open " position), user is by control handle 30 from " holding is beaten
Open " position is rotated clockwise to " closing " position.When user attempt control handle 30 is clockwise from " staying open " position
When rotating to " closing " position, in order that the distal end of securing rod 44 is not stopped by fixed block 60, it may be necessary to which user presses again
Press the first button 40.However, it is necessary to it is probably undesirable that user presses the first button 40 again.Alternatively, securing rod 44
(that is, the securing rod engaged with fixed block) can have inclined surface 50, be rotated when control handle 30 is set from " staying open "
When being set to " closing ", the inclined surface engages with fixed block.This engagement between inclined surface and fixed block upcountry pushes away
Dynamic securing rod 44 (towards bar 36), set with allowing control handle to rotate back to " closing " in the case where the first button 40 need not be pressed
Put.In other words, although being necessary to press the first button 40 so that knob 30 rotates to " staying open " and set from " closings " setting
Put, but the first button 40 of unnecessary pressing rotates to " closing " setting so that knob 30 is set from " staying open ".Once lock
Fixed block 60 is passed through in the distal end rotation of fixed pole 44, and the first button will be displaced outwardly and return due to outwards biasing with securing rod 44
To their initial position.
The other shapes of the distal end of securing rod 44 and fixed block 60 are feasible, as long as providing counterclockwise from " closing " position
The expectation for rotating to " staying open " position stops (during except the first button of pressing or similar means), and control handle can
From " staying open " position be rotated clockwise to " closing " position expectation allow (preferably regardless of whether pressing the first button or
Similar means).
Fixed block 60 includes thin metal tabs.In alternative embodiment, fixed block can be thicker.If fixed block compared with
Thickness, it may be desirable that having inclined surface for fixed block, rotated to when control handle 30 is set from " staying open "
When " closing " is set, this inclined surface engages with the inclined surface of securing rod.Have on both securing rod and fixed block and tilt
The expectation that surface can advantageously promote securing rod inwardly promotes, to allow control to revolve in the case where that need not press the first button
Button rotates to " closing " setting.
Fixed block can have any appropriate height, and this provides to rotate counterclockwise to from " closing " position and " keeps beating
Open " expectation of position stops (during except the first button of pressing or similar means), but the interference control of this not meeting other modes
The operation or rotation of knob processed.
It is described above to be, once the distal end rotation of securing rod 44 discharges the first button by fixed block 60 and user
40, the first button will be displaced outwardly with securing rod 44 due to outwards biasing and return to their original locations.In other words,
When control handle is located at " staying open " position, securing rod away from each other and does not contact with fixed block.In the alternative of the present invention
In embodiment, the size of securing rod and/or fixed block can design and/or be positioned so as to securing rod and keep connecing with fixed block
Touch, and when control handle is located at " staying open " position, securing rod keeps inwardly promoting.
It may be desirable that when control handle is located at " closing " position, the several years between securing rod and fixed block be present
Revolution space, to help to ensure inside motion of the fixed block without interference with securing rod.
