Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A pressure cooking appliance, a control method thereof and a control apparatus thereof according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of a pressure cooking appliance according to an embodiment of the present invention.
As shown in fig. 1, a control method of a pressure cooking appliance according to an embodiment of the present invention includes the steps of:
and S1, acquiring the pressure value in the pressure cooking appliance in the process of controlling the pressure cooking appliance to cook.
In an embodiment of the present invention, the pressure cooking appliance may be a rice cooker with a pressure cooking function, i.e., a pressure rice cooker. In other embodiments of the present invention, the pressure cooker may be one of an electric pressure cooker and a gas pressure cooker.
Specifically, after the pressure cooking appliance is started and starts a cooking work, the real-time temperature in the pressure cooking appliance is detected to obtain the real-time pressure in the pressure cooking appliance, and it should be noted that the temperature value in the pressure cooking appliance can be converted into the pressure value through a preset algorithm.
And S2, judging whether the pressure value in the pressure cooking utensil reaches the preset bumping pressure value or not. The preset bumping pressure value may be calibrated according to actual conditions, for example, the preset bumping pressure value may be 1.3 standard atmospheric pressures, i.e., bumping pressure values, wherein the standard atmospheric pressure may be 101.325 kPa.
Specifically, after the pressure cooking appliance acquires the pressure value inside itself, it may be determined whether the pressure value inside the pressure cooking appliance reaches a preset bumping pressure value. It should be understood that the preset bumping pressure value described in this embodiment may be stored in a storage space of the pressure cooking appliance, wherein the storage space is not limited to a physical-based storage space, such as a hard disk, and the storage space may also be a storage space (cloud storage space) of a network hard disk connected to the pressure cooking appliance.
For example, after the pressure cooking appliance obtains the pressure value inside the pressure cooking appliance, the preset bumping pressure value can be directly called from the storage space of the pressure cooking appliance, and whether the pressure value inside the pressure cooking appliance reaches the preset bumping pressure value or not can be judged.
S3, if the pressure value in the pressure cooking appliance reaches the preset bumping pressure value, controlling the pressure relief valve of the pressure cooking appliance to continuously open through the preset safe pressure relief opening so as to perform bumping pressure relief on the pressure cooking appliance. Wherein, the weight of pressure release valve can be markd according to actual conditions, and predetermined safe pressure release opening can be markd according to actual conditions.
In one embodiment of the invention, the opening of the pressure relief valve of the pressure cooking appliance can be controlled by controlling the opening angle of the pressure relief valve of the pressure cooking appliance. Wherein, the opening angle can be any value of 5-15 degrees.
Specifically, when the pressure cooking appliance judges that the pressure value in the pressure cooking appliance reaches the preset bumping pressure value, the pressure relief valve of the pressure cooking appliance is controlled to be continuously opened at a rate of 5 degrees, so that the pressure relief valve of the pressure cooking appliance can be continuously opened through a preset safety pressure relief opening, and the pressure cooking appliance is subjected to bumping pressure relief.
In an embodiment of the present invention, the controlling the pressure relief valve of the pressure cooking appliance to continuously open through the preset safety pressure relief opening may include controlling the pressure relief valve of the pressure cooking appliance to continuously open through the preset safety pressure relief opening at a first preset speed for a first preset time, and then controlling the pressure relief valve of the pressure cooking appliance to continuously open through the preset safety pressure relief opening at a second preset speed, wherein the first preset speed is lower than the second preset speed. The first preset speed and the second preset speed can be calibrated according to actual conditions, and the first preset time can be calibrated according to actual conditions.
It should be noted that, because the pressure difference between the inside and the outside of the pressure cooking appliance is relatively large when the pressure relief valve of the pressure cooking appliance is just opened, the slow opening is beneficial to slowing down the gas rushing out at once, and the pressure difference between the inside and the outside of the pressure cooking appliance becomes smaller after a period of time (for example, 15 seconds), so that the exhaust speed can be increased (that is, the opening speed of the pressure relief valve of the pressure cooking appliance is increased), and the overall exhaust is uniform.
In an embodiment of the present invention, as shown in fig. 2, controlling the pressure relief valve of the pressure cooking appliance to be continuously opened with a preset safety pressure relief opening may include the following steps:
and S11, controlling a pressure relief valve of the pressure cooking appliance to open a preset safety pressure relief opening for a second preset time. And the second preset time can be calibrated according to the actual condition.
And S12, after delaying the third preset time, controlling the pressure relief valve of the pressure cooking appliance again to continuously open the preset safe pressure relief opening for the second preset time, and repeatedly executing the step S11. And the third preset time can be calibrated according to the actual condition.
For example, when the pressure cooking appliance determines that the pressure value inside the pressure cooking appliance reaches the preset bumping pressure value, the pressure relief valve of the pressure cooking appliance may be controlled to continuously open for a preset safe pressure relief opening for a period of time (for example, 20 seconds), then the pressure relief valve of the pressure cooking appliance may be stopped from opening for a period of time (for example, 10 seconds), and then the above control may be repeated until the pressure relief valve of the pressure cooking appliance reaches the maximum opening, or the pressure inside and outside the pressure cooking appliance is substantially equal to stop the pressure relief valve of the pressure cooking appliance from opening.
It should be noted that the continuous opening amplitude described in the above embodiments may be slow first and then fast, or may be constant.
In summary, the control method of the pressure cooking appliance provided by the embodiment of the invention can control the pressure relief valve of the pressure cooking appliance to be continuously opened through the preset safe pressure relief opening, so that the safety of the pressure cooking appliance is improved, the purpose of reminding a user of bumping pressure relief can be achieved, and the user experience is improved.
In addition, in one embodiment of the invention, when the pressure value in the pressure cooking appliance reaches the preset bumping pressure value, whether a person is in the preset range of the pressure cooking appliance is detected through the induction sensor, and when no person is in the preset range, the pressure relief valve of the pressure cooking appliance is controlled to be opened through the maximum opening, so that the pressure cooking appliance is subjected to bumping pressure relief.
The induction sensor can be an infrared sensor, an ultrasonic sensor or a voice recognition sensor, and the preset range can be calibrated according to actual conditions. In other embodiments of the present invention, the inductive sensor may be installed around the pressure cooking device, the upper cover, and other places beneficial for detecting the approach of foreign objects, and the preset range is also a range within a certain distance around the pressure cooking device.
In another embodiment of the present invention, when the pressure value in the pressure cooking appliance reaches the preset bumping pressure value, if someone is in the preset range of the pressure cooking appliance, the pressure relief valve of the pressure cooking appliance is controlled to continuously open with the preset safety pressure relief opening, so as to perform bumping pressure relief on the pressure cooking appliance.
Specifically, when the pressure cooking appliance judges that the pressure value inside the pressure cooking appliance reaches the preset bumping pressure value, whether people exist in a certain distance around the pressure cooking appliance can be detected through the infrared sensor, and when no people are detected, the pressure relief valve of the pressure cooking appliance can be controlled to be opened through the maximum opening so as to perform bumping pressure relief on the pressure cooking appliance, so that a user is prevented from being injured.
When a person is detected, the pressure cooking appliance can control the pressure relief valve of the pressure cooking appliance to continuously open at the rate of a preset safety pressure relief opening (for example, an opening of 5 degrees) so as to carry out bumping pressure relief on the pressure cooking appliance.
Further, in an embodiment of the present invention, when the pressure cooking appliance is controlled to perform bumping pressure relief, the pressure cooking appliance is also controlled to send out a warning message, and the operation interface of the pressure cooking appliance is disabled and the upper cover of the pressure cooking appliance is locked until the bumping pressure relief is completed.
Specifically, when the pressure cooking appliance performs sudden-boiling pressure relief, the pressure cooking appliance can control the alarm prompting device to send out warning information, for example, when the alarm prompting device is a buzzer, the pressure cooking appliance can send out a buzzing warning sound through the buzzer, so as to remind a user that the pressure cooking appliance is performing sudden-boiling pressure relief. Meanwhile, the pressure cooker also disables the operation interface of the pressure cooker and locks the upper cover of the pressure cooker until the bumping pressure relief is completed, so that the upper cover is prevented from being separated to cause danger when the pressure cooker performs the bumping pressure relief.
In other embodiments of the present invention, the alarm device may also be a voice prompt device, and can prompt according to the cooking state of the pressure cooking appliance, so as to facilitate the user to know the condition of the food in the pressure cooking appliance.
To make the present invention more apparent to those skilled in the art, fig. 3 is a flowchart of a control method of a pressure cooking appliance according to one embodiment of the present invention. As shown in fig. 3, the control method of the pressure cooking appliance may include the steps of:
and S101, starting the pressure cooking appliance and starting cooking.
