The invention relates to a side door switching mechanism, especially to a side door switching mechanism for a toaster.
To put a toast to an existing toaster to bake it or to take it from the toaster, the user opens the side doors of the toaster by controlling the handle or the button of the toaster. The handle or the button is disposed in the side doors. The closing of the side doors of the toaster also occurs with the button or handle. But the temperature of the side doors of the existing toaster rises with the rising of the temperature of the toaster. So the user may be hurt by the high temperature of the side door when opening or closing the side door.
In some embodiments, a side door switching mechanism for a toaster including pivots is provided. The side door switching mechanism comprises first and second side doors having lower ends pivotably connected to the toaster by the pivots. First and second sharing shafts are provided. First and second thermal rings are disposed on the first and second sharing shafts respectively. A side door open lock catch includes lock catches to lock the first and second side doors. The lock catches are disposed in the toaster. The lock catches have a first lock catch for locking the first side door, and a second lock catch for locking the second side door. A hook of the first lock catch is connectable to the first thermal ring, and a hook of the second lock catch is connectable to the second thermal ring. The side door open lock catch also includes a gear structure disposed in the toaster. The lock catches connect to the gear structure. The gear structure includes a first joint gear lever and a second joint gear lever joined together. The first joint gear lever has an end that is connectable to the first lock catch along the first sharing shaft. The second joint gear lever has an end connectable to the second lock catch along the second sharing shaft. The side door switching mechanism also includes a side door closing lifting device which includes a lifting board slidingly connected to a front body of the toaster, and side door shafts fixed to bottoms of the first and second side doors. The side door shafts are disposed under the lifting board and the lifting board is placed against the side door shafts. A reset control device is disposed in the toaster and connects to the lifting board.
Compared to the existing art, the user pushes the closing push rod with the lifting board pressing the side door pivot to close the side doors automatically in the present invention. The lock catch is lifted by the effect of the gear lever when the open push rod is pressed. Then the side door is opened. The closing push rod and the open push rod are disposed far away from the side door, so that the components would not be affected by the temperature of the toaster, the components are adiabatic. The invention prevents the user from hurting themselves by the side door.
The invention will be further described with the drawings and the embodiment.

The invention is provided with a side door switching mechanism for a toaster, which includes:
two side doors 1, the bottom of which pivot connect to the two side surfaces of the toaster separately by the pivots 12, two side door thermal baffles 11 are disposed in the inner surface of the side door. A groove 111 is disposed on the top of the thermal baffle 11, and the groove 111 works with the hook of the lock catch 21, the hook of the lock catch 21 could insert to the groove 111; the pivot connects to the side door by hole clearance, and the pivot is positioned by the spring and the convex (not shown in the figures); the side door pivot 32 is fixed to the side door 1 by bolts; the inner of the thermal baffle is disposed with grid spring 112 to open the side door;
A side door open lock catch device 2, which includes two lock catch 21 to lock the two side door and a gear structure 22. The lock catch 21 connects to the gear structure 22, which drives the lock catch 21 to lock the lock catch 21 to the groove 111 or release the lock catch 21 from the groove 111; the gear structure 22 of the side door open lock catch device 2 includes two gear levers 221, 222, which joints together; the end of the gear levers 221,222 connect to the lock catch 21 in a sharing shaft 23. Thermal ring 24 is disposed in the sharing shaft 23, and the lock catch 21 pivot connects to the thermal ring 24 by the sharing shaft 23. A lock catch spring 211 is disposed under the lock catch 21 to reset the lock catch 21; a gear spring 223 is disposed at the joint of the two gear lever 221,222 to reset the gear lever; an open push rod 25 is disposed at the joint of the two gear lever 221,222; Side door lifting device 3, which includes a lifting board 31 and two side door shaft 32 fixed to the bottom of two the side doors 1. The lifting board 31 sliding connects to the front body 5 of the toaster. The side door shaft 32 are disposed under the lifting board 31, a closing push rod 33 connects to the lifting board 31. The bottom of the lifting board 31 extends down to form a side door push piece 311 to press the side door shaft; the bottom of the lifting board is disposed with a lifting spring 34 to reset the lifting board; the two sides of the front body 5 is disposed with a stop 51 to limit the pivot angle of the side door shaft.
The timing electromagnetic controller 4 includes a timing controller 41 and an electromagnetic device 42. The electromagnetic device 42 is disposed in the base 6 of the toaster. The timing controller 41 of the timing electromagnetic controller 4 is disposed with a knob 411 to select the bake time. The timing controller 41 is disposed with an electromagnet 421 which is magnetized when powered; an suction piece 312 (or a magnetic piece) is fixed at the bottom of the lifting board 31, the suction piece 312 can stick to the electromagnet 421.
