It should be noted that, in the embodiment, the time for automatically locking the door body 110 after being closed may be set by the controller, that is, the controller controls the lock pin 140 to lock the door after the door body 110 is closed for a period of time, for example, the time for automatically locking the door after the door body 110 is closed for 5 seconds is set, so as to achieve the purpose of delaying locking the door, improve the flexibility of use, and set the time for delaying locking the door according to different use requirements, which is not limited herein.
Referring to fig. 1 and 2, the locking device is installed inside the control panel 120, so that the installation space of the control panel 120 can be effectively utilized, and the installation is more convenient, wherein fig. 1 is a front view of the control panel 120 and the door body 110, and fig. 2 is a back view of the control panel 120 and the door body 110.
Referring to fig. 3, the driver is specifically an electric push rod 130, the electric push rod 130 includes a motor 131 and a push rod 132, the motor 131 drives the push rod 132 to move linearly through a transmission assembly, for example, the motor 131 drives the push rod 132 to move telescopically after being decelerated by a gear or a worm gear, and the specific structure of the electric push rod 130 is not described again. The locking pin 140 is provided at an end of the push rod 132, and a through hole (not shown) corresponding to the locking pin 140 is provided on the control panel 120, so that the locking pin 140 can be driven to extend out of the control panel 120 or retract into the control panel 120 by the electric push rod 130.
Referring to fig. 1, specifically, the control panel 120 is located on the right side of the door body 110, the through hole is located on the side of the control panel 120, and the electric push rod 130 and the electric control board 150 are both fixed inside the control panel 120. The end of the lock pin 140 is provided with a lock tongue 141, the lock tongue 141 is matched with the through hole, a lock groove is arranged on one side of the door body 110 facing the control panel 120, the lock groove corresponds to the lock tongue 141, when the door body 110 is closed and the electric push rod 130 pushes the lock pin 140 to extend, the lock tongue 141 can penetrate through the through hole and be inserted into the lock groove, the door body 110 is locked by matching the lock tongue 141 and the lock groove, the structure is stable and reliable, the door body 110 cannot be directly opened, the difficulty in opening the door is increased, and the door is safer and more reliable.
Referring to fig. 4, the controller includes an electric control board 150 and a switching device, the electric control board 150 is connected to the switching device, the switching device is connected to the motor 131 of the electric push rod 130, the electric control board 150 is used for sending a control signal to the switching device according to an operation instruction of a user, and the switching device controls a rotation direction of the motor 131 according to the control signal, so that it can be understood that the push rod 132 can be driven to extend or retract by using forward rotation and reverse rotation of the motor 131.
Referring to fig. 4 and 5, specifically, the motor 131 is powered by a dc power source 151 of an electronic control board 150, the electronic control board 150 may be a control circuit board of a microwave oven, and the electric push rod 130 is installed above the electronic control board 150, so as to facilitate the connection between the electronic control board 150 and the electric push rod 130. When the positive and negative electrodes of the motor 131 are energized, the motor 131 is controlled to rotate forward or backward by a switching device, which is understood to be a component capable of automatically switching according to a control signal of a controller, in the embodiment, the switching device is a relay 160, and the motor 131 has a control terminal for forward and backward rotation, which is connected to the relay 160. When the door body 110 is closed, the controller acquires that the state of the door body 110 is a closed state, the controller cannot trigger the relay 160 to work at the moment, the relay 160 is in a disconnected state, the motor 131 rotates forwards and drives the push rod 132 to extend out of the furnace body, and therefore the door body 110 is locked; on the contrary, when the door body 110 is opened, the controller acquires that the state of the door body 110 is the opened state, and at the moment, the controller sends a control signal to the relay 160 to attract the relay 160, so that the motor 131 rotates reversely and drives the push rod 132 to return to the furnace body, thereby unlocking the door body 110.
Referring to fig. 1 and 5, an unlocking button 121 is disposed on the control panel 120, the unlocking button 121 is connected to the controller, and an instruction can be given to the electronic control board 150 by pressing the unlocking button 121, so that the door 110 is unlocked. The specific principle is that after the unlocking button 121 is pressed, the electric control board 150 outputs a control signal to the relay 160, the relay 160 is attracted to enable the motor 131 to rotate reversely, the electric push rod 130 drives the bolt 141 to retract into the furnace body, and therefore the door body 110 is unlocked. It is understood that in some embodiments, the door 110 may be unlocked and then re-locked after a certain time interval. For example, when the door 110 is not opened within 5 seconds after unlocking, the electric control board 150 turns off the control signal of the relay 160, at this time, the relay 160 is turned off, the motor 131 rotates forward, and the electric push rod 130 drives the bolt 141 to extend to lock the door again, so that the safety is further improved.
Referring to fig. 5, it can be understood that, when the oven door is kept in the open state, the electronic control board 150 continuously outputs a control signal to the relay 160, the relay 160 keeps in the pull-in state, so that the electric push rod 130 drives the latch 141 to stay in the oven body, that is, the door body 110 is always in the unlock state, thereby preventing the latch 141 from extending out and affecting the closing of the door body 110, when the door needs to be closed, the door body 110 can be automatically locked by closing the door body 110, the door body 110 does not need to be closed after being additionally manually unlocked, and the door is more convenient to use, and the latch 141 is not exposed, thereby not affecting the appearance, and being more practical and reliable.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
