Reset control device, which is disposed in the toaster and connects to the lifting board.
In another preferred embodiment, a grid spring to open the side door is disposed in the inner of the side door.
In another preferred embodiment, a groove is disposed on the top of the side door to work with the lock catch.
In another preferred embodiment, a lock catch spring is disposed between the lock catch and the toaster to reset the lock catch.
In another preferred embodiment, a lifting spring to reset the lifting board is disposed under the lifting board.
In another preferred embodiment, a closing push rod is fixed in the lifting board; the side surface of the front body of the toaster is disposed with a stop to limit the pivot angles of the side door shaft.
In another preferred embodiment, the reset control device includes a timing electromagnetic controller, the timing electromagnetic controller includes a timing controller and an electromagnetic device, the timing controller connects to the electromagnetic device by electric control line, and the electromagnetic device is disposed at the bottom of the toaster.
In another preferred embodiment, the electromagnetic device of the timing electromagnetic controller is disposed with an electromagnet, which is magnetized when powered, a suction piece is disposed at the bottom of the lifting board, the suction piece can stuck to the electromagnet.
In another preferred embodiment, the toaster is disposed with two side doors, the gear structure of the side door opening lock catch includes two gear levers joint together; the end of the two gear levers connects to the lock catch of the side surface separately along a sharing shaft, thermal rings are disposed to the sharing shaft, the lock catch pivot connects to the thermal ring on the sharing shaft.
In another preferred embodiment, the joint of the two gear levers is disposed with a spring to reset the gear levers, an open push rod is disposed at the joint of the two gear levers.
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 patent for 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 patent for invention prevents the user hurt by the side door.
The patent for invention will be further described with the drawings and the embodiment.
In the figures, 1—side door, 11—side door thermal baffle, 111—groove, 112—grid spring, 12—pivot, 13—pivot fixing piece, 2—side door open lock catch, 21—lock catch, 211—lock catch spring, 212—lock catch spring shaft, 22—gear structure, 221—left gear lever, 222—right gear lever, 223—lever spring, 23—sharing draft, 24—thermal ring, 25—open push rod, 3—d side door close lifting device, 31—lifting board, 311—side door push piece, 312—electromagnetic suction piece, 32—side door shaft, 33—closing push rod, 34—lifting spring, 4—timing electromagnetic controller, 41—timing controller, 411—knob, 42—electromagnetic device, 421—electromagnet, 43—power control line, 5—front body, 51—stop, 6—base
The patent for 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.
