The rolling member C passes from one side of the boss along the surface to the other side of the boss, the elastic member is deformed, and the door body 121 is switched between a closed state and an open state.
The rolling element C is disposed on the third slide bar 33, the first elastic member B1 is disposed on an elastic member retaining seat B ', the elastic member retaining seat B' is connected with the third slide bar 33, and an elastic member stopper B is disposed at an end of the first elastic member B1 away from the third slide bar 33.
In one example, the side of the second rotating plate 1222″ is provided with a protrusion that abuts the door body installation tube a, and the abutment of the protrusion with the door body installation tube a can increase a damping force when the second rotating plate 1222″ rotates so that the door body 121 can be stopped at an angle.
The pressing piece 123 is disposed at the other end of the rotating assembly 1222, i.e., the end of the rotating assembly 1222 remote from the fixing piece 1221, and the pressing piece 123 is coupled to the rotating assembly 1222 such that the pressing piece 123 can move or slide in the door body 121 as the rotating assembly 1222 rotates.
The contact switch 124 is disposed on the door body 121 and is located within a moving or sliding range of the pressing piece 123 within the door body 121, the pressing piece 123 can contact with the contact switch 124 as the pressing piece 123 moves or slides within the door body 121, and when the pressing piece 123 contacts with the contact switch 124, the contact switch 124 is turned on, the toaster 100 is started, and the toaster 100 starts to operate. As the tab 123 is moved or slid within the door 121, the tab 123 can be disconnected from the contact switch 124, and when the tab 123 is disconnected from the contact switch 124, the toaster 100 is closed and the toaster 100 is stopped.
In one example, the tab 123 is mounted at the opening of the door mounting tube a, the tab 123 extends out of the door mounting tube a to contact the contact switch 124, and the tab 123 retracts into the door mounting tube a to disconnect from the contact switch 124.
In one example, the first elastic member B1 includes a compression spring, and the second elastic member B2 includes a tension spring.
When the door body 121 is rotated to be closed, the one-end rolling member C of the rotating assembly 1222 is engaged with the surface of the boss of the fixed member 1221, the rolling member C passes from one side of the boss along the surface to the other side of the boss, the second elastic member B2 is changed from a free state to a compressed state, and when the door body 121 is rotated to be opened, the one-end rolling member C of the rotating assembly 1222 is engaged with the surface of the boss of the fixed member 1221, the rolling member C passes from the other side of the boss along the surface to the one side of the boss, and the second elastic member B2 is changed from a compressed state to a free state.
Specifically, when the door body 121 is rotated to be closed, the one-end rolling member C of the rotating assembly 1222 is engaged with the surface of the boss of the fixed member 1221, the rolling member C passes from one side of the boss along the surface to the other side of the boss, the rolling member C is pressed in this process, the rolling member C moves the third slide rod 33 upward, the upward movement of the third slide rod 33 moves the elastic member holder B ' upward, and the upward movement of the elastic member holder B ' presses the second elastic member B2 between the elastic member holder B ' and the elastic member stopper b″. When the door 121 is rotated to be opened, the rolling member C at the one end of the rotating member 1222 is engaged with the surface of the boss of the fixed member 1221, the rolling member C passes from the other side of the boss along the surface to the one side of the boss (opposite to the path when the door is closed), the rolling member C is disengaged from the surface of the boss after passing to the one side of the boss, the rolling member C no longer abuts against the surface of the boss, the surface of the boss no longer exerts an upward force on the rolling member C, the rolling member C moves downward to a certain extent, the downward movement of the rolling member C moves the third slide bar 33 downward, the downward movement of the third slide bar 33 moves the elastic member holder B 'downward, and the downward movement of the elastic member holder B' gradually changes the first elastic member B1 from the compressed state to the free state.
In addition to the radial distance difference of the door body 121 and the rotating assembly 1222 due to the different axial rotations thereof, the movement of the pressing piece 123 contributes to the effects of the first and second elastic members B1 and B2 below. The first elastic member B1 and the second elastic member B2 function as follows:
As described above, when the door 121 is rotated to be closed, the second elastic member B2 is changed from the free state to the compressed state, the pressed second elastic member B2 applies the upward pressure to the elastic member stopper B ", and the upward movement of the second rotating plate 1222" drives the first rotating plate 1222' to move upward due to the elastic member stopper B "being disposed on the second rotating plate 1222", and the pressing piece 123 is disposed at the end of the first rotating plate 1222', so that the upward movement of the first rotating plate 1222' drives the pressing piece 123 to move upward.
As described above, when the door body 121 is rotated to be opened, the second elastic member B2 is changed from the compressed state to the free state, during which the upward force of the first elastic member B1 against the elastic member stopper b″ is gradually reduced to 0, the elastic member stopper b″ is gradually lowered, and since the elastic member stopper b″ is disposed on the second rotating plate 1222", the second rotating plate 1222" is downwardly moved, the downward movement of the second rotating plate 1222 "drives the first rotating plate 1222' to be downwardly moved, and the pressing piece 123 is disposed at the end of the first rotating plate 1222', so that the upward movement of the first rotating plate 1222' drives the pressing piece 123 to be downwardly moved.
The first elastic member B1 provides a buffering force for closing the door body, which buffers the impact of the contact between the pressing piece and the contact switch, and prolongs the life of the contact switch.
The first elastic member B1 and the second elastic member B2, or the first elastic member B1 provides a pre-tightening force for the closing state of the door body, and the pre-tightening force enables a user to open the door body at will, so that the situation that the door body is easily opened when the heating device is switched on to cause the user to be scalded by high-temperature steam in the oven can be prevented.
In summary, the contact switch is arranged on the door body, the switch is linked with the opening and closing of the door body, the cooking device is simplified to have a simplified structure, the first elastic member B1 and the first elastic member B2 provide buffering force and pretightening force for the closing of the door body, the buffering force buffers the impact of the pressing sheet and the contact switch in contact, the service life of the contact switch is prolonged, the pretightening force enables a user to be unable to open the door body at will, and thus the situation that the door body is easily opened when the heating device is turned on to cause the user to be scalded by high-temperature steam in the oven is prevented.
