Specify micro-wave oven operation of the present invention with reference to the accompanying drawings.
Shown in Fig. 7 a, open at rotary door 33 under the state of cooking room 31 of micro-wave oven, put into plate 41 in the inside of cooking room.And the gathering sill 44 that plate 41 its two ends shown in Fig. 7 b are directed to device 43 inserts guiding, and moves to the cooking room rear.In addition, before the installation of plate 41 or after installing, the top placement food of plate.
And plate 41 was pushed projection 73 by the button 70 of pressing to cooking room 31 internal protrusion before 44 li of gathering sills that inserts guider 43.Push projection 73 and be the through hole 31b that connects cooking room 31 1 sides to internal protrusion.Therefore, the button body 71 of button 70 moves to cooking room 31 lateral direction.
At this moment, the guide hook 75 of button 70 call-on button body 71 under the state of 63 li of the gathering sills that inserts above-mentioned base plate 60 moves.And the interlock groove 65 that the gangbar 76 of button 70 connects base plate 60 rotates to identical direction together with button body 71.In addition, when button body 71 moved, the helical spring between base plate 60 and the button 70 was compressed by button body 71.
The linkage portion 83 of gangbar 76 push levers 80 of Yi Donging like this.Therefore, linkage portion 83 is that rotate at the center with rotation section 81, and catches up with from the operate portions that linkage portion 83 front ends prolong and to state linkage portion 83 and rotate to identical direction together.
The front end of operate portions 85 is pushed the mobile terminal of change-over switch 90, it is contacted, thus change-over switch 90 closures with change-over switch 90.Because of change-over switch 90 closure input electrical signals, so in abutting connection with cooking room 31 back and vertical rotation heater 39 forward rotation, be that counter clockwise direction among accompanying drawing 7a and Fig. 7 b is rotated.
Both, the rotation of rotating heater 39 was carried out simultaneously with the runnings of 31 li installations of cooking room plate 41.
In addition, according to change-over switch 90 closures, the signal of telecommunication of input, so drive motors 105 forward drive, promptly the clockwise direction among Fig. 7 b drives.
Shown in Fig. 7 c, when moving, plate 41 contacts the insertion guide part 101 contact-making surface 101a on its mobile route under the state that inserts 44 li of guider 43 gathering sills.But, insert guide part 101 and under the state of eccentric combination on drive motors 105 driving shafts, be driven motor 105 drives and forward rotation, promptly the clockwise direction among the figure rotates.
Therefore, plate 41 is inserted into guide part and stops and temporarily stop to move.Thus, the user learns and rotates the place that heater 39 does not arrive maximum magnitude.
At this moment, moving by its front end of plate 41 is stuck in the scope that can not hinder 39 rotations of rotation heater.The stagnation of such plate 41 stopping period shown in Fig. 7 b: because of till inserting guide part 101 clockwise direction being rotated in the forward contact-making surface 101a and breaking away from plate 41 mobile routes in the accompanying drawings.
In addition, rotary driving part 103 is inserted into guide part 101 drives and rotates to same direction.Rotary driving part 103 approximately rotates about 90 ° from primary position, makes the 1st shutdown switch 108 closures.
Therefore, according to the signals of telecommunication of importing because of the 1st shutdown switch 108 closures, drive motors 105 stops to be rotated in the forward, and the insertion guide part also stops operating according to these.
In addition, if drive motors 105 stops forward drive, insert guide part 101 and also stop as the state of about 90 ° of rotary driving part 103 about rotations.In this state, insertion guide part 101 breaks away from from the mobile route of plate, breaks away from distance to a declared goal so insert the noncontact face 101b of guide part 101 from plate 41.
Therefore, plate 41 can not be installed to 31 li of cooking rooms being subjected to inserting the influence of guide part 101.In addition, rotating heater 39 continues shown in Fig. 7 d, to be parallel to the bottom surface of cooking room 31 to counterclockwise rotating on drawing.
Behind 31 li installations of cooking room plate 41, rotary door 33, sealing cooking room 31.And if by control part 35 input operation signals, heater 37,39 is according to the operation signal heating of input.The food of 41 li on the direct radiation plate of the heat of Jia Re fixed heater 37 like this, the heat that rotates heater 39 is delivered on the food above it by plate 41.
Then, the cooking food that plate is 41 li is isolated plate 41 for 31 li from cooking room after finishing.At this moment, the process of isolating plate 41 from 31 li of cooking rooms is just in time opposite with the process that plate 41 is installed.
At first, rotary door 33, open cooking room 31.
Under cooking room 31 opened state, pull out plate 41 to the outside from 31 li of cooking rooms.But, the distance to a declared goal because insertion guide part 101 disengaging plates 41 mobile routes, plate 41 and noncontact face 101b are separated by is so isolating the process of plate 41 from cooking room 31, insert guide part 101 guiding plates 41 and move, prevent that plate from being interfered in the process that moves.
And, isolate plate 41 from cooking room 31 after, button body 71 is subjected to helical spring elastic force to cooking room 31 medial movement, pushes projection 71 simultaneously and connects through hole 31b to cooking room 31 inner protrusions.In addition, gangbar 76 also moves to the moving direction of button body 71, so the external force of rotation control rod 80 is also eliminated.
But the mobile terminal 91 of change-over switch 90 is subjected to breaking away from the direction elastic force of fixed terminal, and the operate portions 85 of promptly controlled bar 80 is pushed and mobile opposite direction elastic force.So mobile terminal 91 breaks away from from fixed terminal, change-over switch 90 disconnects thus.In addition, according to moving of mobile terminal 91, control lever 80 returns to initial position with rotation section 81 for the counter-rotation of middle mind-set change-over switch 90 closures.
According to disconnecting the signal of telecommunication of importing, rotation heater 39 counter-rotatings parallel, i.e. clockwise direction in the accompanying drawings with cooking room 31 bottom surfaces because of change-over switch 90.In addition, disconnection running according to change-over switch 90, input makes the signal of telecommunication of above-mentioned drive motors 105 reverse drivings, so insert guide part 101 according to drive motors 105 reverse drivings and counter-rotating returns to original position and is positioned at again on the mobile route of plate 41.
And rotary driving part 103 is also with inserting guide part 101 counter-rotating together.Therefore, the 1st shutdown switch 108 by rotary driving part 103 closures disconnects the 2nd shutdown switch 109 closures.
According to importing the signal of telecommunication that makes drive motors 105 stop reverse driving, so drive motors 105 stops counter-rotating because of such the 2nd switch 109 closures.
As mentioned above, basic fundamental thought of the present invention is: come control heater to rotate by the change-over switch that turns round according to installation plate in the cooking room, and utilize plate guider control plate temporarily to stop to move.
In basic thought scope of the present invention, those skilled in the art can carry out more distortion.And interest field of the present invention will serve as that explain on the basis with the patent request scope of annex.
