Description
Technical field
The utility model relates to a kind of safety switches for Steam roaster.
Background technique
Steam roaster is a kind of multifunctional household electrical appliance for having steam cooking and toasting performance, is typically provided with safety open
It closes, prevents that maloperation causes oven to start work when opening because of chamber door, and occur steam or heat is blown out human body of burning
Accident.In the prior art, chamber door Gai Hehou, be equipped with by chamber door pushing block insertion cabinet on notch in touch safety open
Connection is logical, after opening chamber door, then is resetted by elastic component, disconnection safety switch, but safety switch fully relies on elastic component
Homing action is carried out, elastic inadequate or failure is caused after being used for a long time such as elastic component, then can not be completed homing action and cause to pacify
Full switch cannot disconnect, and keep safety switch ineffective.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of novel Steam roaster safety switch.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of safety switch of Steam roaster is equipped at the top of the chamber door and pushes away including cabinet and rotation hinged chamber door
Block, the cabinet are equipped with the notch being inserted into for pushing block, are equipped with safety switch in the notch, the safety switch includes runner
And the microswitch with spring contact, the runner excircle are equipped with the drive lugs and spring contact cooperated with pushing block
Pressing convex block, the barb and release link with pushing block cooperation of cooperation, the drive lugs aligned notches, when chamber door is closed,
The pushing block enters notch and drive lugs is pushed to drive runner rotation, and the pressing convex block, which moves down, to be touched below runner
Microswitch spring contact, the barb, which moves up, to be buckled into the bayonet of the pushing block；The end of the release link is connected with bullet
Property part realize runner elastic reset.
The drive lugs are convexly equipped with boss towards notch direction.
The contact surface of the pressing convex block and spring contact is cambered surface.
The microswitch is installed on mounting base by claw.
The elastic component is torsional spring, and one end of torsional spring is fixedly mounted on bottom plate, and the other end is connect with release link.
The beneficial effects of the utility model are: the safety switch of the utility model includes runner, microswitch, chamber door lid
It closes, the notch that the pushing block on chamber door enters cabinet pushes drive lugs to drive the runner rotation under initial position, moves up barb
It buckles into the bayonet of pushing block, pressing convex block moves down the spring contact of pressing microswitch, and connection safety switch enables the normal work of oven
To make, chamber door is opened, and pushing block pulls barb by bayonet, and it enables the rotation of runner opposite direction on pressing convex block and is moved away from spring contact,
So that runner is restored initial position by the elastic component between release link and mounting base again, make to press convex block far from spring contact,
The utility model no longer fully relies on elastic component and completes homing action, and first passes through pushing block and pull barb, turns runner opposite direction
Command of execution pressing convex block is detached from spring contact to disconnect safety switch in advance, no longer influences safety elastic component is damaged and failed
The reset of switch disconnects.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of safety switch when chamber door is opened；
The structural schematic diagram of safety switch when Fig. 2 is chamber door closure；
Fig. 3 is the partial enlarged view of Fig. 2；
Fig. 4 is the structural schematic diagram of runner.
Specific embodiment
Referring to figs. 1 to a kind of safety switch of Steam roaster of Fig. 3, including the hinged chamber door 1 of cabinet 2 and rotation, case
1 top of door is equipped with pushing block 11, and pushing block 11, which is inserted into the notch 21 of cabinet 2, pushes safety switch 3；Safety switch 3 include runner 4 and
Microswitch 5 with spring contact 51, the pressing that 4 excircle of runner is equipped with drive lugs 41, cooperates with spring contact 51
Convex block 42, the barb 43 cooperated with pushing block 11 and release link 44,41 aligned notches 21 of drive lugs, when closing chamber door 1, pushing block
11, which enter notch 21, pushes drive lugs 41 that runner 4 is driven to rotate, and barb 43 moves up in the bayonet 12 for buckling into pushing block 11, by belling
Block 42 moves down the spring contact 51 that touching is located at 4 lower section of runner, makes the connection of safety switch 3 that oven be enabled to work normally, when oven work
It finishes, opens chamber door 1, pushing block 11 pulls barb 43 by bayonet 12, makes the rotation of 4 opposite direction of runner that pressing convex block 42 be enabled to move up
Spring contact 51 is left, safety switch 3 is enabled to disconnect in advance, then by being connected with elastic component 7 between release link 44 and mounting base 6
Runner 4 is set to restore initial position.
The utility model safety switch no longer fully relies on elastic component 7 and carries out homing action, even if the damage failure of elastic component 7
Also the reset for no longer influencing safety switch 3 disconnects, and safety switch 3 is enable to be always maintained at normal work.
Referring to Fig. 4, as a preferred embodiment of the present invention, the drive lugs 41 of runner 4 are convexly equipped with towards 21 direction of notch
Boss 46 makes the push rod 11 of chamber door 1 push rotation convex block 41 by boss 46, drives runner 4 to realize the rotation of greater angle, make
Barb 43 can be easier to buckle into the bayonet 12 of pushing block, and press convex block 42 towards being cambered surface at spring contact 51, make by belling
Block 42 can preferably press spring contact 51, and safety switch 3 is made to keep connection.
Preferably, runner 4 and microswitch 5 are assembled on mounting base 6 and are fixed on cabinet 2 by mounting base 6
Inside, elastic component 7 are torsional spring, and one end of torsional spring is fixedly mounted on bottom plate 6, and the other end is connect with release link 44；Under runner 4
The microswitch 5 of side is installed on mounting base 6 by claw 61, and runner 4 and microswitch 5 are respectively independently installed, works as part
After impaired, it is convenient for changing.
