Detailed description of the invention
Be below the preferred example of baking box automatic safety door lock system described in the utility model, therefore do not limit protection domain of the present utility model.
Please refer to Fig. 1, there is shown a kind of baking box automatic safety door lock system, comprising electromagnetic relay 1, motor 2, door open switch 3, switch 4 of locking a door, door lock hook 5 and the temperature controller 6 for detecting oven temperature.
In this enforcement, the model of described electromagnetic relay 1 can be set to Omron MY2F110/120VAC.As shown in Figure 2, described electromagnetic relay 1 has 8 pins, and wherein, 1,2 pin are normally closed pin, and 3,4 pin are for often to open pin, and 5,6 pin are public pin, and 7,8 pin are coil pin.
In this enforcement, the desired temperature of temperature controller 6 is 280 DEG C ~ 320 DEG C, and when temperature controller 6 detects the temperature of baking box higher than 280 DEG C ~ 320 DEG C, temperature controller 6 is in on-state, when temperature controller 6 detects the temperature of baking box lower than 280 DEG C ~ 320 DEG C, temperature controller 6 is in off-state.It should be noted that at this, the desired temperature of temperature controller 6 also can change according to actual needs, and non-enforcement is limited.
In this enforcement, motor 2 is preferably set to gear motor.
Below the annexation of all parts to baking box automatic safety door lock system is described in detail.
As depicted in figs. 1 and 2, the first coil pin (i.e. the 7th pin) of electromagnetic relay 1 is connected with the negative pole of power supply respectively with the first public pin (i.e. the 5th pin), the second public pin (i.e. the 6th pin) of electromagnetic relay 1 is connected with the positive pole of power supply, temperature controller 6 is connected between the second coil pin (i.e. the 8th pin) of electromagnetic relay 1 and the positive pole of power supply, door open switch 3 is connected between the first normally closed pin (i.e. the 1st pin) of electromagnetic relay 1 and the first link of motor 2, switch 4 of locking a door is connected on first of electromagnetic relay 1 and often opens between pin (i.e. the 3rd pin) and the first link of motor 2, the second normally closed pin (i.e. the 2nd pin) and second of electromagnetic relay 1 is often opened pin (i.e. the 4th pin) and is connected with the second link of motor 2 respectively, the turning cylinder of motor 2 is equiped with can when rotating pressing door open switch 3 or the switch 4 thus make door open switch 3 or switch 4 of locking a door to be become the cam 7 of off-state from on-state of locking a door, cam 7 is at door open switch 3 and lock a door between switch 4, cam 7 is connected with a drive link 8, door lock hook 5 is in transmission connection by drive link 8 and cam 7.
Operating principle of the present utility model is as follows:
After external power source is connected, heat up in the inside of baking box from room temperature, now temperature controller 6 not yet detects that the temperature of baking box is higher than 280 DEG C ~ 320 DEG C, the internal switch access failure of temperature controller 6, first normally closed pin of electromagnetic relay 1 and the first public pin (i.e. 1-5), second normally closed pin and the second public pin (i.e. 2-6) are in on-state respectively, motor 2 takes cam 7 to and rotates, when cam 7 is pressed into door open switch 3 in rotation, the internal switch of door open switch 3 becomes off-state from original on-state, motor 2 power-off decommissions, door lock hook 5 is in opening,
Along with the internal temperature of baking box constantly raises, when temperature reaches 280 DEG C ~ 320 DEG C, the internal switch of temperature controller 6 is connected, first coil pin of electromagnetic relay 1 and the second coil pin (i.e. 7-8) are connected and are produced electromagnetism adhesive, now first of electromagnetic relay 1 often open pin and the first public pin (i.e. 3-5), second often opens pin and the second public pin (i.e. 4-6) is connected respectively, motor 2 is energized and is with moving cam 7 to rotate, when cam 7 be pressed into lock a door switch 4 time, switch 4 of locking a door becomes off-state from original on-state, motor 2 power-off decommissions, door lock hook 5 is in locking states,
When the internal temperature of baking box is reduced to again lower than 280 DEG C ~ 320 DEG C, the internal switch of temperature controller 6 becomes off-state from on-state, first coil pin and the second coil pin (i.e. 7-8) of electromagnetic relay 1 disconnect, now first of electromagnetic relay 1 often open pin and the first public pin (i.e. 3-5), second often opens pin and the second public pin (i.e. 4-6) disconnects respectively, first normally closed pin of electromagnetic relay 1 and the first public pin (i.e. 1-5), second normally closed pin and the second public pin (i.e. 2-6) return to on-state, motor 2 is with moving cam 7 to rotate until be pressed into door open switch 3, door open switch 3 becomes off-state from original on-state, motor 2 power-off stops action, now door lock hook 5 returns to opening.
In sum, the utility model can detect the temperature of baking box to control the on off operating mode of electromagnetic relay 1 by temperature controller, thus control the running of the motor 2 be in transmission connection with door lock hook, realize the automatic unlatching of door lock or automatically close, it is reasonable in design, and safety is high and user can be made to avoid the danger of scalding.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
