Description

Technical Field

[0001] The present application relates to the field of smart furniture, and in particular to a cooking device and an anti-overflow exhaust method. Background Art

[0002] Existing cooking equipment such as electric pressure cookers, pressure cookers, and pressure stews usually need to release the pressure in the pot by exhausting after cooking. However, during the exhaust process, due to the sudden drop in pressure, the ingredients are prone to tumbling under the pressure, posing a risk of overflow. To avoid this problem, existing equipment generally adopts an intermittent exhaust method with a longer exhaust interval and a shorter exhaust duration to slow down the exhaust speed. Although this method can reduce the overflow of ingredients to a certain extent, due to the lack of flexibility in the exhaust process, it often leads to a longer time to open the lid after cooking, affecting the efficiency of use.

[0003] Further analysis shows that most cooking appliances currently on the market rely on single-point controlled pressure switches to manage pressure. Once this pressure switch is triggered, it is impossible to monitor and respond to the dynamic changes in the pressure in the pot in real time, resulting in a relatively extensive exhaust control method. Existing equipment can only rely on preset time intervals for exhaust, and cannot be dynamically adjusted according to the actual pressure changes in the pot. This static exhaust mode is not only difficult to accurately control the exhaust speed, but may also increase the risk of food overflow due to uneven pressure release, while prolonging the time the user waits to open the lid, reducing the user experience. Therefore, the existing exhaust method has obvious deficiencies in both safety and efficiency, and is in urgent need of improvement. Summary of the invention

[0004] In order to overcome at least one of the defects described in the above-mentioned prior art, the present application provides a cooking device and an anti-overflow exhaust method, which can monitor the pressure value inside the pot body in real time to dynamically adjust the opening time of the exhaust mechanism and the time interval between two adjacent openings of the exhaust mechanism to achieve optimized exhaust rhythm.

[0045] Embodiment 2:

[0046] See also Figure 3 This embodiment discloses an anti-overflow exhaust method, which is applied to the cooking device as described above. The anti-overflow exhaust method comprises the following steps:

[0047] S1: obtaining the pressure value inside the pot body 1 in real time through the monitoring mechanism 3;

[0048] Specifically, the pressure change inside the pot body 1 is monitored in real time by the pressure sensor in the monitoring mechanism 3 to obtain the pressure value inside the pot body 1 .

[0049] S2: Determine whether the pressure value inside the pot body 1 is greater than P1. If so, drive the exhaust mechanism 2 to open for a duration of T2 at each interval T1 and execute S1. If not, execute S3.

[0050] Specifically, the internal pressure value of the pot body 1 obtained by the monitoring mechanism 3 is called to determine whether the pressure value inside the pot body 1 is greater than P1. Preferably, if the pressure value inside the pot body 1 is less than or equal to P1, S3 is executed; if the pressure value inside the pot body 1 is greater than P1, the exhaust mechanism 2 is driven to open for a duration of T2 at each interval T1, that is, when the pressure value inside the pot body 1 is greater than P1, the exhaust mechanism 2 is first closed for a duration of T1, and then the exhaust mechanism 2 is driven to open for exhaust for a duration of T2, and this cycle is repeated while continuing to execute S1 to continuously obtain the pressure value inside the pot body 1 in real time.

[0051] S3: Determine whether the pressure value inside the pot body 1 is greater than P2. If so, drive the exhaust mechanism 2 to open for a duration of T4 at each interval T3 and execute S1. If not, execute S4.

[0052] Specifically, if the pressure value inside the pot body 1 is less than or equal to P1, it is continued to be determined whether the pressure value inside the pot body 1 is greater than P2. Preferably, if the pressure value inside the pot body 1 is less than or equal to P2, S4 is executed. If it is determined that the pressure value inside the pot body 1 is greater than P2, which means that the pressure value inside the pot body 1 is greater than P2 and less than or equal to P1 at this time, the exhaust mechanism 2 is driven to open for T4 duration at every interval time. In this way, when the pressure value inside the pot body 1 is greater than P2 and less than or equal to P1, the exhaust mechanism 2 is first closed and lasts for T3 duration, and then the exhaust mechanism 2 is driven to open to exhaust and lasts for T4 duration. This cycle is repeated while S1 is continued to be executed to continuously obtain the pressure value inside the pot body 1 in real time.

[0053] S4: Determine whether the pressure value inside the pot body 1 is greater than P3. If so, drive the exhaust mechanism 2 to open at every interval T5 and last for T6, and execute S1. If not, execute S5.

[0054] Specifically, if the pressure value inside the pot body 1 is less than or equal to P2, it is continued to be determined whether the pressure value inside the pot body 1 is greater than P3. Preferably, if the pressure value inside the pot body 1 is less than or equal to P3, S5 is executed. If the pressure value inside the pot body 1 is greater than P3, that is, it means that the pressure value inside the pot body 1 is greater than P3 and less than or equal to P2 at this time, the exhaust mechanism 2 is driven to open for a duration of T6 at each interval T5. In this way, when the pressure value inside the pot body 1 is greater than P3 and less than or equal to P2, the exhaust mechanism 2 is first closed and lasts for T5, and then the exhaust mechanism 2 is driven to open to exhaust and lasts for T6. This cycle is repeated while S1 is continued to be executed to continuously obtain the pressure value inside the pot body 1 in real time.

[0055] S5: At each interval T7, the exhaust mechanism 2 is driven to open for a duration of T6, and the program ends after time T8.

[0056] Specifically, if the pressure value inside the pot body 1 is less than or equal to P3, the exhaust mechanism 2 is driven to open for a duration of T6 at each interval T7, and the program ends after time T8, that is, the exhaust mechanism 2 is driven to close for a duration of T7, and then the exhaust mechanism 2 is driven to open for exhaust for a duration of T6, and the cycle is repeated for a duration of T8, and the program ends after a duration of T8.

[0057] In this embodiment, P1>P2>P3, and time T1, time T3, time T5 and time T7 satisfy: T1>T3>T5>T7, time T2, time T4 and time T6 satisfy: T6>T4>T2. In this way, as the pressure value inside the pot body 1 decreases, the closing time of the exhaust mechanism 2 decreases, and the opening exhaust time of the exhaust mechanism 2 increases, thereby realizing real-time monitoring of the pressure value inside the pot body 1 through the monitoring mechanism 3, dynamically adjusting the opening time of the exhaust mechanism 2 and the time interval between two adjacent openings of the exhaust mechanism 2, optimizing the exhaust rhythm, and being able to speed up the exhaust process and shorten the exhaust waiting time without overflowing the food, thereby greatly improving the user experience.

[0058] Embodiment three:

[0059] This embodiment also discloses an anti-overflow exhaust method, which is applied to cooking equipment. The anti-overflow exhaust method described in this embodiment is mainly different from the above-mentioned anti-overflow exhaust method in that:

[0060] The S4 is specifically implemented by the following steps:

[0061] S41: Determine whether the pressure value inside the pot body 1 is greater than P31. If so, drive the exhaust mechanism 2 to open for a duration of T6 at each interval T51 and execute S1. If not, execute S42.

[0062] Specifically, if the pressure value inside the pot body 1 is less than or equal to P2, it is continued to be determined whether the pressure value inside the pot body 1 is greater than P31. Preferably, if the pressure value inside the pot body 1 is less than or equal to P31, S42 is executed. If the pressure value inside the pot body 1 is greater than P31, which means that the pressure value inside the pot body 1 is greater than P31 and less than or equal to P2 at this time, the exhaust mechanism 2 is driven to open for a duration of T6 at each interval T51. In this way, when the pressure value inside the pot body 1 is greater than P31 and less than or equal to P2, the exhaust mechanism 2 is first closed and lasts for T51, and then the exhaust mechanism 2 is driven to open for exhaust and lasts for T6, and this cycle is repeated while S1 is continued to be executed to continuously obtain the pressure value inside the pot body 1 in real time.

[0063] S42: Determine whether the pressure value inside the pot body 1 is greater than P32. If so, drive the exhaust mechanism 2 to open for a duration of T6 at each interval T52 and execute S1. If not, execute S43.

[0064] Specifically, if the pressure value inside the pot body 1 is less than or equal to P31, it is continued to determine whether the pressure value inside the pot body 1 is greater than P32. Preferably, if the pressure value inside the pot body 1 is less than or equal to P32, S43 is executed. If the pressure value inside the pot body 1 is greater than P32, that is, it means that the pressure value inside the pot body 1 is greater than P32 and less than or equal to P31 at this time, the exhaust mechanism 2 is driven to open for a duration of T6 at each interval T52. In this way, when the pressure value inside the pot body 1 is greater than P32 and less than or equal to P31, the exhaust mechanism 2 is first closed and lasts for T52, and then the exhaust mechanism 2 is driven to open for exhaust and lasts for T6. This cycle is repeated while S1 is continued to be executed to continuously obtain the pressure value inside the pot body 1 in real time.

[0065] S43: Determine whether the pressure value inside the pot body 1 is greater than P33. If so, drive the exhaust mechanism 2 to open for a duration of T6 at each interval T53 and execute S1. If not, execute S5.

[0066] Specifically, if the pressure value inside the pot body 1 is less than or equal to P32, it is continued to be determined whether the pressure value inside the pot body 1 is greater than P33. Preferably, if the pressure value inside the pot body 1 is less than or equal to P33, S5 is executed. If the pressure value inside the pot body 1 is greater than P33, that is, it means that the pressure value inside the pot body 1 is greater than P33 and less than or equal to P32 at this time, the exhaust mechanism 2 is driven to open at every interval T53 and lasts for T6. In this way, when the pressure value inside the pot body 1 is greater than P33 and less than or equal to P32, the exhaust mechanism 2 is first closed and lasts for T53, and then the exhaust mechanism 2 is driven to open for exhaust and lasts for T6. This cycle is repeated while S1 is continued to be executed to continuously obtain the pressure value inside the pot body 1 in real time.

[0067] In this embodiment, P31>P32>P33, time T5, time T52 and time T53 satisfy: T5>T52>T53. In this way, as the pressure value inside the pot body 1 decreases, the closing time of the exhaust mechanism 2 decreases, and the opening time of the exhaust mechanism 2 remains unchanged, so that in the same cycle, as the pressure value inside the pot body 1 decreases, the closing time of the exhaust mechanism 2 is shortened, thereby increasing the number of opening times of the exhaust mechanism 2, effectively speeding up the exhaust process and shortening the exhaust waiting time without overflowing the food, greatly improving the user experience.

[0068] Furthermore, when the difference between P31 and P32 and the difference between P32 and P33 are small enough, time T51, time T52 and time T53 can satisfy: T51≥T52≥T53. Preferably, time T51, time T52 and time T53 can satisfy: T51=T52=T53, that is, when the pressure value inside the pot body 1 changes little, the closing time and opening time of the exhaust mechanism 2 remain unchanged to avoid multiple violent tumbling of the food during exhaust, resulting in overflow of the food.

In this way, when the pressure value inside the pot body 1 is greater than P16 and less than or equal to P15, the exhaust mechanism 2 is first closed and lasts for T15, and then the exhaust mechanism 2 is driven to open to exhaust and lasts for T2. This cycle is repeated while S1 is continued to be executed to continuously obtain the pressure value inside the pot body 1 in real time.

[0084] In this embodiment, P11>P12>P13>P14>P15>P16, and T11>T12>T13>T14>T15>T16. In this way, as the pressure value inside the pot body 1 decreases, the closing time of the exhaust mechanism 2 decreases, and the opening time of the exhaust mechanism 2 remains unchanged, so that in the same cycle, as the pressure value inside the pot body 1 decreases, the closing time of the exhaust mechanism 2 is shortened, thereby dynamically increasing the number of openings of the exhaust mechanism 2, optimizing the exhaust rhythm, and effectively speeding up the exhaust process and shortening the exhaust waiting time without overflowing the food, greatly improving the user experience.
