Products, methods, and the like will be described in detail below with reference to basic designs, extended designs, and alternative designs.
A control method of a cooking appliance is applied to the cooking appliance, and the cooking appliance can comprise a pressure cooker, an electric cooker and the like. It includes: the pot body and lid, the internal pot of placing of pot, the lid includes inner cup and apron subassembly, covers including the detachable installation of apron subassembly, and when the lid closed on the pot body, lid and interior pot formed airtight space for the culinary art. In order to form a closed space between the cover body and the inner pot during pressure cooking, the cover plate assembly cannot be accidentally pushed open by high pressure, the inner cover of the cooking appliance is provided with a lock catch, and the cover body and the inner pot can be locked together or unlocked under the action of the driving structure by the lock catch. The locking and unlocking of the lock catch are controlled by the control method. On the other hand, the cover body of the cooking utensil is provided with the pressure relief hole and the pressure control small ball, the pressure control small ball is controlled by the small ball push rod, when the pressure control small ball falls on the pressure relief hole, air leakage in the pressure relief hole can be prevented, so that the pressure of the closed space between the cover body and the inner pot is ensured to be gradually increased, and when the pressure control small ball is separated from the pressure relief hole, the air in the closed space can be discharged through the pressure relief hole. The position relation between the pressure control small ball and the pressure relief hole is also controlled by the control method. Next, the two times of pressure-up and pressure-down are specifically described as an example, as shown in fig. 1:
the cooking operation is a preliminary stage of the overall cooking process. Taking rice as an example, the stage comprises:
the water absorption stage is a non-pressure cooking stage, so that the motor is in a standby state. And (5) entering a heating stage after water absorption is finished.
This step is carried out in the water absorption stage, and the process proceeds to step 114 at the latter stage of the water absorption stage.
This step is based on the cooking appliance being powered on and receiving a cooking program start signal, which in various embodiments may come from various means, such as manually selecting a cooking program start; for another example: automatic control, through automatic judgement such as culinary art time, the culinary art state of culinary art food, the atmospheric pressure value of airtight space between interior pot and apron, belong to the preliminary step of procedure, when circular telegram back, the automation immediately gets into the culinary art procedure and starts. Of course, other programs may be connected, and when the previous program is finished, the program automatically enters the cooking program starting step.
In the step, only the cooking program starting signal is obtained, and based on the signal, the driving motor is controlled to drive the lock catch to lock the cover body and the inner pot. The hasp needs to be with lid and interior pot locking, and drive structure forward rotates in order to drive the hasp and to interior pot edge removal, and the hasp is with lid and interior pot locking.
Such as: the driving structure pushes the transmission frame to be close to the cooking appliance; the transmission frame guides the guide rod of the lock catch support to move through the guide groove, and the guide rod is arranged in the guide groove; the lock catch support drives the lock catch to move towards the edge of the inner pot, and the cover body and the inner pot are locked by the lock catch.
The locking method of the locker will be described later in connection with the structure of the cooking appliance.
It is clear that the lid and the inner pot are only in contact at the initial stage of cooking, and the closed space is at normal pressure. As the liquid in the pan boils, steam is generated and, if further cooking is desired, a pressure cooking stage can be entered. After the heating stage is carried out for a period of time, the food and the water are heated, and steam appears, and whether the pressure cooking stage is started or not is judged according to the judgment condition. It should be noted that the user may select pressure cooking directly at this stage, or at the initial start-up. The system can be directly locked and pressed subsequently when the system is selected at the initial starting, or can be automatically controlled to lock and press as the cooking time is prolonged.
In the pressure cooking stage, the driving structure continues to rotate forward in the rotation direction locked by the lock catch to drive the small ball push rod to move so as to push the pressure control small ball to the pressure relief hole. Such as: the driving structure (such as a driving motor) continues to drive the transmission frame to move, the transmission frame drives the small ball push rod to move, the pressure control small ball is driven to move to the pressure release hole, the closed space is really closed, and gas leakage is prevented. The judgment condition whether the pressure control small ball is pushed to the pressure relief hole is as follows: when the pressure control ball is positioned above the pressure relief hole, the first microswitch is triggered; when the first microswitch is triggered, the driving structure stops rotating in the positive direction.
In the stage, the cover plate and the inner pot are locked by the lock catch, and the pressure control ball blocks the exhaust passage, so that the pressure raising stage belongs to the pressure raising stage of the closed space in the pot.
The pressure of the closed space formed by the cover plate and the inner pot is gradually increased, and when the pressure reaches a preset pressure value, the process can proceed to step 120.
The driving structure continues to rotate reversely to drive the small ball push rod to move so as to pull the pressure control small ball to be separated from the pressure relief hole. Such as: the driving motor overturns to drive the transmission frame to move reversely, the transmission frame drives the small ball push rod to move, the small ball push rod drives the pressure control small ball to be separated from the pressure release hole, and the closed space (or called closed space) is released with pressure. After the pressure relief is completed, step 122 is performed.
In the pressure cooking stage, the driving structure continues to rotate forward in the rotation direction locked by the lock catch to drive the small ball push rod to move so as to push the pressure control small ball to the pressure relief hole. Such as: the driving structure (such as a driving motor) continues to drive the transmission frame to move, the transmission frame drives the small ball push rod to move, the pressure control small ball is driven to move to the pressure release hole, the closed space is really closed, and gas leakage is prevented. The judgment condition whether the pressure control small ball is pushed to the pressure relief hole is as follows: when the pressure control ball is positioned above the pressure relief hole, the first microswitch is triggered; when the first microswitch is triggered, the driving structure stops rotating in the positive direction. The enclosed space is pressurized again.
At this stage, the cover body and the inner pot are locked by the lock catch all the time, and the pressure control ball is positioned on the pressure release hole. Along with the prolonging of the cooking time, the air pressure of the closed space is gradually increased to form a high-pressure atmosphere.
After a certain time, entering a stewing stage.
And step 124, controlling the cooking utensil to be in a pressure relief state, and after the pressure control ball is separated from the pressure relief hole, controlling the lock catch to unlock the cover body and the inner pot to enter a rice stewing stage.
At this stage, the cover body and the inner pot are unlocked, the pressure control ball is far away from the pressure release hole, and the air pressure of the closed space is gradually reduced to the normal pressure. The user can open the cover at this stage, add rice, add steamed food, hot dish etc..
In other embodiments, the rice cooking can be finished directly after the rice stewing or the rice cooking can be finished after the heat preservation stage.
In other embodiments, a detection step may be added in step 116 to detect whether the ball pushing rod pushes the pressure control ball to the pressure relief hole, and when the pressure control ball is located on the pressure relief hole, the driving structure stops rotating, and step 116 is ended. Therefore, step 116 may include the following steps, as shown in FIG. 2:
step 1161, judging whether the cooking enters a pressure cooking stage;
step 1162-1-1, when the judgment result is that the ball enters, the driving mechanism continues to rotate in the rotation direction (such as positive rotation) during locking, and the small ball push rod is pushed to drive the small ball to move;
step 1162-1-2, detecting signals of the micro switch at the position of the small ball push rod, and if the signals exist, stopping the rotation of a driving mechanism (such as a driving motor); if there is no signal, the drive mechanism continues to rotate and step 1162-1-2 is again performed.
And step 1162-2, if the pressure cooking stage is not started, continuing to perform normal pressure cooking.
It should be noted that, in the specific embodiments, the operation of the cooking appliance is described by taking cooking as an example, and in other embodiments, cooking may be replaced by other cooking manners.
Of course, in other embodiments, other determination methods may be used to determine the stop timing of the drive mechanism. Such as: the moving distance and the moving direction of the small ball push rod are determined through the size of the guide groove and the trend of the groove, and the small pressure control ball is ensured to just fall on the pressure relief hole.
For the cooking utensil safety, before controlling the lock catch to lock the cover body and the inner pot based on the cooking program starting signal, the control method can also increase the self-checking that the locking and the unlocking of the lock catch of the cooking utensil are controllable: that is, in some embodiments, step 108 may also be added before step 110: the freely opened and closed cover of the cooking utensil lock catch is self-checked so as to promote the rice cooker to be freely opened and closed in a starting state. As shown in fig. 3, the method specifically includes the following sub-steps:
step 108-1, electrifying the cooking appliance;
step 108-2, acquiring signals of a microswitch in the cooking appliance, wherein the signals comprise: switching on and off;
