Technical Field

The invention relates to the field of cooking appliances, in particular to a cooking appliance, an exhaust control method and device thereof, a storage medium and a processor.

Background

For cooking appliances (such as an electric pressure cooker), in order to cook food and improve the nutritive value of the cooked food, a solenoid valve control system can be installed on the cooking appliances, and the pressure limiting valve is pushed by a solenoid valve to perform exhaust operation, so that the pressure state in the cooking appliances can be adjusted.

However, when the amount of food in the pot body is relatively large, the conventional electromagnetic valve exhaust device often causes the food in the pot to overflow due to too large exhaust amount, and the exhaust is poor. In order to solve the above problems, the prior art provides a new exhaust control method, as disclosed in the patent application No. 201410289140.5, which can select the exhaust mode according to the food type and adjust the frequency of exhaust by the pressure in the pressure cooking appliance.

Example 1

In accordance with an embodiment of the present invention, there is provided an embodiment of an exhaust control method for a cooking appliance, it is noted that the steps illustrated in the flowchart of the drawings may be carried out in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be carried out in an order different than that presented herein.

Fig. 1 is a flowchart of an exhaust control method of a cooking appliance according to an embodiment of the present invention, as shown in fig. 1, the exhaust control method including the steps of:

step S102, obtaining the current pressure inside the pot body of the cooking utensil.

Specifically, the cooking appliance may be an electric pressure cooker, and the electric pressure cooker may sequentially perform a heating and warming cooking stage, a pressure maintaining cooking stage, and an exhaust cooking stage in a cooking process, so as to complete the whole cooking operation, wherein in the pressure maintaining cooking stage, in order to maintain the pressure in the electric pressure cooker at a cooking pressure preset by a user, the pressure inside the cooker body needs to be exhausted through a pressure limiting valve when the pressure exceeds the cooking pressure, for example, the pressure limiting valve may be pushed by a control solenoid valve to perform an exhaust operation; in the exhaust cooking stage, in order to reduce the pressure inside the pot body, the pressure limiting valve is required to exhaust, and for example, the pressure limiting valve can be pushed by a control solenoid valve to perform exhaust operation. Therefore, in the process of executing cooking operation by the cooking appliance, the current pressure inside the pot body needs to be acquired in real time, and in the actual use process, the current pressure inside the pot body can be detected through the pressure detection device arranged inside the cooking appliance.

And step S104, judging whether the current pressure is greater than a first preset pressure.

Optionally, the first preset pressure is 85kP.

Specifically, in the process of executing cooking operation of the cooking appliance, when the current pressure inside the pot body is higher, the pressure inside the pot body can directly jack the pressure limiting valve open for exhausting, and in order to prevent the pressure limiting valve from being pushed over by the electromagnetic valve while being jacked open by the pressure inside the pot body, the minimum pressure capable of jacking the pressure limiting valve open, namely the first preset pressure, needs to be preset. The first preset pressure may be selected according to the weight of the pressure limiting valve installed on the cooking appliance and the size of the vent hole during actual use, and may be determined within a range of 80-100kP during actual use, and in a preferred embodiment of the present invention, the first preset pressure may be set to 85kP.

And step S108, if the current pressure is greater than the first preset pressure, closing the electromagnetic valve.

Specifically, under the condition that the current pressure inside the pot body exceeds a first preset pressure, the pressure inside the pot body can be determined to directly jack the pressure limiting valve open for exhausting, the electromagnetic valve can be controlled to be closed in order to prevent the pressure limiting valve from being overturned, the electromagnetic valve does not push the pressure limiting valve, the pressure limiting valve is automatically jack by the pressure inside the pot body for exhausting, and therefore the pressure inside the pot body is reduced.

It should be noted that, when the pressure maintaining cooking stage is ended and before the exhaust cooking stage is started, the pressure inside the pot body of the cooking appliance may be reduced to be lower than the first preset pressure, that is, the current pressure inside the pot body is less than or equal to the first preset pressure, so that the current pressure inside the pot body may not be greater than the first preset pressure during the exhaust cooking operation of the cooking appliance. Therefore, in the actual use process, only in the process of the pressure maintaining cooking stage of the cooking appliance, whether the current pressure inside the pot body is greater than the first preset pressure or not is judged.

According to the embodiment of the invention, the current pressure in the pot body of the cooking appliance is obtained, whether the current pressure is greater than the first preset pressure or not is judged, and if the current pressure is greater than the first preset pressure, the electromagnetic valve is controlled to be closed. It is easy to notice that, when the current pressure is greater than the first preset pressure, the electromagnetic valve is closed, the pressure limiting valve is not pushed, and the pressure limiting valve is automatically pushed by the pressure in the cooker, so that the exhaust control is realized according to the internal condition of the cooker body of the cooking utensil, and the phenomenon that the pressure in the cooker body is too high, the electromagnetic valve pushes the pressure limiting valve to cause the pressure limiting valve to be overturned is avoided, thereby achieving the technical effects of improving the safety and the reliability of the cooking utensil and improving the intelligence of the cooking utensil, and further solving the technical problem that the risk of the pressure limiting valve being overturned exists because the electromagnetic valve pushes the pressure limiting valve to exhaust in the prior art.

In the practical use process, in order to reduce the continuous opening times of the electromagnetic valve and shorten the cooking time, the electromagnetic valve can be controlled to be continuously opened twice, and simultaneously, in order to ensure that the pressure in the cooker body can be timely reduced, the electromagnetic valve can be controlled to be opened for 0.2-0.5s each time, the interval time of opening for two times is 0.5-1s, and the electromagnetic valve is closed for 10-60s after being continuously opened twice.
