As shown in fig. 1 to 5, the present application provides a control method of a cooking appliance, the cooking appliance including an up-pressing stage, a pressure maintaining stage, and an exhaust stage, the control method including: step S1: during the exhaust stage, the cooking appliance intermittently exhausts, the cooking appliance exhausts for a first preset time period T1, and the cooking appliance stops exhausting for a second preset time period T2, wherein the first preset time period T1 is greater than the second preset time period T2.

By applying the technical scheme, when the cooking utensil enters the exhaust stage, the electric pressure cooker intermittently exhausts air and prevents food from overflowing. Meanwhile, the first preset duration T1 is longer than the second preset duration T2, that is, the exhaust time is longer than the exhaust stopping time. The exhaust mode can reduce the total time of exhaust, can enable a user to quickly open a cover after cooking is finished, and improves the use experience of products. Therefore, the technical scheme of the application solves the problems that the exhaust time of the electric pressure cooker in the prior art is long and the user experience is poor.

The following will describe in detail the specific implementation of four examples of the control method of the cooking appliance of the present application:

embodiment one:

the intermittent air discharge means that the cooking device is alternately operated in the "air discharge-non-air discharge" state during the air discharge phase.

It should be further noted that, the above-mentioned pressing stage refers to: heating the cooking utensil after the cooking utensil is electrified, and raising the pressure in the cooker body from zero to rated pressure or preset pressure; the pressure maintaining stage refers to: maintaining the pressure in the pot body of the cooking appliance at a rated pressure or a preset pressure for a certain time, wherein in the stage, the pressure maintaining is usually realized by adopting a discontinuous heating mode, and the food cooking is realized in the stage; the exhaust stage described above refers to: after the cooking utensil is finished, in order to enable the user to normally uncap, the pressure in the pot body needs to be reduced to the safe level, and at the moment, the exhaust structure of the cooking utensil exhausts air and accelerates the speed of reducing the pressure of the pot body. The pressure-up stage, the pressure-maintaining stage and the exhaust stage are all cooking appliances, particularly common cooking stages in pressure cookers and electric pressure cookers, and specific cooking parameters thereof are not repeated.

As shown in fig. 1, in the first embodiment, the cooking appliance starts intermittent air discharge after entering the air discharge stage. In this process, the cooking appliance exhausts for a first preset period T1 and stops exhausting for a second preset period T2. In the first embodiment, the first preset duration T1 is longer than the second preset duration T2, so that the total exhaust time of the cooking appliance is longer, that is, the exhaust amount is larger in the exhaust stage, thereby reducing the total exhaust time and realizing quick cover opening.

Further preferably, in the first embodiment, the first preset time period T1 is equal and the second preset time period is always equal in each cycle. The time of the exhaust process is exemplified below by "first preset time T1-second preset time period T2", each cycle being comma separated. The duration of the exhaust phase is: "30 seconds to 10 seconds, 30 seconds to 10 seconds … …". When the pressure in the pot body is reduced to the pressure at which the user can uncover, the exhaust phase is ended.

Example two

As shown in fig. 3, in the technical solution of the second embodiment, the difference between the technical solution and the first embodiment is that step S3 is further performed after step S1 is performed, where step S3 is: and continuously exhausting the cooking utensil when the cooking utensil is intermittently exhausted and the pressure is reduced to the preset pressure. Specifically, when the cooking appliance is continuously exhausted for a certain time, the pressure in the pot body is reduced to a certain level, and the probability of food overflow is low. In this case, if intermittent exhaust is continued, time is wasted and the exhaust time is prolonged. Therefore, in the second embodiment, as shown in fig. 3, when the pressure in the pot body is reduced to the preset pressure, the exhaust structure starts to exhaust continuously until the pressure in the pot body is reduced to the safety cover opening pressure.

Further, the selection of the preset pressure may be in various manners, for example, the preset pressure may be made to be less than or equal to 30 kpa. For another example, the ratio of the preset pressure to the rated pressure may be made smaller than or equal to 3:4. in fact, those skilled in the art can obtain that, according to a limited number of experiments, when the pressure in the pot body is less than a certain value, the phenomenon of food overflow does not occur basically when the cooking utensil is exhausted. The person skilled in the art can thus make an adaptive selection for the preset pressure according to different product sizes and parameters.

In the second embodiment, when the related sensor detects that the pressure in the pan body is less than the preset pressure, the cooking appliance enters a continuously exhausting state no matter the cooking appliance is in an exhausting state or a non-exhausting state.

The specific exhaust manner of step S1 in the second embodiment is the same as that in the first embodiment, and will not be described here again.

Implementation three

As shown in fig. 4, in the solution of the third embodiment, the difference from the first embodiment is that step S2 is further performed before step S1. Specifically, step S2 includes: during the exhaust stage, the cooking appliance intermittently exhausts, the cooking appliance exhausts for a third preset time period T3, and the cooking appliance stops exhausting for a fourth preset time period T4. When the cooking appliance starts the exhaust phase, the third preset time period T3 is smaller than the fourth preset time period T4, the third preset time period T3 gradually increases and the fourth preset time period T4 gradually shortens until the third preset time period T3 is equal to the fourth preset time period T4, and preferably, the step S1 further includes: the first preset time period T1 gradually increases, and the second preset time period T2 gradually shortens.

That is, in the third embodiment, the cooking appliance still performs intermittent air discharge, but the air discharge time and the non-air discharge time are not equal for each cycle during the intermittent air discharge. When the exhaust stage starts to be started, the third preset time period T3 is smaller than the fourth preset time period T4, and the condition that food overflows due to the fact that the pressure in the pot body is overlarge and long-time exhaust is considered in the stage, so that the exhaust is short and the exhaust is not long. But after each venting, the pressure in the pan is reduced. Thus, in each cycle, the third preset time period T3 gradually increases and the fourth preset time period T4 gradually decreases. That is, the exhaust time is gradually increased, and the time of no exhaust is gradually shortened. Until the exhaust time exceeds the time of no exhaust in a certain cycle, that is, the process goes to step S1 until the exhaust is completed.

The time of the exhaust process is exemplified below by a "first preset time period T1-second preset time period T2" or a "third preset time period T3-fourth preset time period T4", each cycle being separated by commas. The duration of the exhaust phase is: "10 seconds to 40 seconds, 20 seconds to 30 seconds, 30 seconds to 20 seconds, 40 seconds to 10 seconds … …". From the above-described exhaust time course, it can be seen that the exhaust time is longer than the non-exhaust time at the beginning of the exhaust phase. In the circulation process, the exhaust time is gradually increased, and the time without exhaust is gradually shortened until the exhaust time exceeds the time without exhaust.

Embodiment three is compared with embodiment one and embodiment two, consider the situation that the pressure in the pot body is too big when beginning the exhaust stage, and reduce even eliminate the possibility that food overflows through step S2 and step S1. Thereby making the whole exhaust process safer.

Example IV

As shown in fig. 5, in the solution of the fourth embodiment, the difference from the third embodiment is that step S3 is further performed after step S1. The specific steps and effects of step S3 in the fourth embodiment are the same as those of the embodiment, and are not described here again. In the fourth embodiment, the conditions of food overflow and air exhaust time are comprehensively considered, so that the time of the air exhaust stage of the cooking appliance is shortened as much as possible under the condition of ensuring no overflow

Further, the control method of the present application further includes: step S4: and stopping heating the cooking utensil within a fifth preset time period T5 before the pressure maintaining stage is finished. Specifically, stopping the heating before the pressure maintaining stage can reduce the pressure inside the pot to some extent. And the pressure in the pot body is reduced by a certain level before entering the exhaust stage. As can be seen from fig. 2 to 5, in the solutions of the first embodiment to the fourth embodiment, the pressure maintaining stage is performed in step S4. Of course, in consideration of the cooking effect and the taste of the food, step S4 may not be performed in the pressure keeping stage

Preferably, in the technical solution of the present application, the fifth preset duration T5 is less than or equal to 10 minutes. Specifically, the fifth preset time period T5 may be selected by a person skilled in the art so as not to affect the taste of the food.

Further, in the technical scheme of the application, the cooking utensil comprises a pot body 10 and a pot cover 20. The pot body 10 is used for containing food to be cooked, and water level scale marks are arranged in the pot body 10. The pot cover 20 is arranged on the pot body 10, and an exhaust structure 30 communicated with the interior of the pot body 10 is arranged on the pot cover 20, wherein a first preset distance is reserved between the highest scale line of the water level scale line and the lower end of the exhaust structure. Preferably, the first preset distance is in the range of 30 to 80 millimeters. Specifically, the water level scale line refers to an indication line for prompting the user how high the water should be added. In the prior art, the highest scale mark of the water level scale mark is higher, so that the water surface is closer to the exhaust structure after the user fills water. Therefore, when the exhaust is performed, if the exhaust time is long, the soup can be easily splashed out of the exhaust port. Therefore, in the prior art, when the cooking utensil is in the exhaust stage, intermittent exhaust adopts a mode of exhausting in a short time and not exhausting for a long time. In this application, the first preset distance is in the range of 30 to 80 mm, so that the distance between the highest scale mark of the water level scale mark and the exhaust structure 30 is further, and therefore, the possibility of splashing of the soup is smaller even if the exhaust time is longer. And the above structure is particularly suitable for the technical solutions of the first embodiment and the second embodiment.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
