Step S101 receives pressure release instruction, determines the pressure release tupe for being directed to relief valve.
Wherein, step 101 receive pressure release instruction, determine for relief valve pressure release tupe can by household appliance come
It realizes；Here, the household appliance can be the household appliance with vacuum decompression function, such as vacuum electrothermal pot, vacuum coffee
Coffee machine etc..By taking the vacuum electrothermal pot as an example, vacuum electrothermal pot may include three sealing cover, cooker body and interior pot parts；Wherein,
Sealing cover is equipped with aspiration pump, which can will stew intracorporal air extraction, so that vacuum state is presented in cooker body；In addition,
Relief valve is provided on sealing cover, the relief valve can be made of electromagnet and sealing ring, can control the opening of pressure relief opening
With closing；The on and off of the relief valve control pressure relief opening can be realized by the control electric signal that processor exports；Tool
Body, processor exports control electric signal according to instruction, and the control electric signal is converted to the thrust of relief valve by household appliance,
And then the opening and closing of pressure relief opening are controlled by the size of relief valve thrust；In a kind of feasible embodiment of the invention
In, when pushing the thrust magnitude of relief valve to be zero, pressure relief opening is in the state of fully opening；When the thrust magnitude for pushing relief valve
When for maximum, pressure relief opening is in the state closed completely；When the half that the thrust magnitude for pushing relief valve is maximum thrust value
When, pressure relief opening is in the state for opening half.
Further, it after household appliance culinary art finishes, needs the household appliance carrying out pressure release；Here, it uses
Family controls the household appliance and executes pressure discharge operations by input pressure release instruction.Correspondingly, household appliance is to receive user defeated
After the pressure release instruction entered, the pressure release tupe for being directed to relief valve is determined by processor；Here, pressure release tupe corresponds to
Different pressure release modes；For example, pressure release tupe may include the number for needing to carry out pressure release, the time for completing pressure release etc..
In other embodiments of the invention, the household appliance, can be according to default item when receiving pressure release instruction
Part determines the pressure release tupe for being directed to relief valve.Here, preset condition may include the current state of household appliance.Namely
Say, the current state of household appliance is different, then it is determined that pressure release tupe it is also just different.
Step 102 is based on pressure release tupe, divides the thrust magnitude of n times adjustment relief valve, so that household appliance is completed
Vacuum state is released after n times pressure release.
Wherein, step 102 is based on pressure release tupe, divides the thrust magnitude of n times adjustment relief valve, so that household appliance exists
Releasing vacuum state can be realized by household appliance after completing n times pressure release.
In other embodiments of the invention, since relief valve can control the on and off of pressure relief opening, pressure release
The thrust magnitude of valve is different, and the size that pressure relief opening is opened is also just different；So, the thrust magnitude for dividing n times adjustment relief valve here,
That is n times is divided to change the size that pressure relief opening is opened；In order to reduce relief valve, to fully open bring in a short time biggish
Impulse force, therefore N can be set to the natural number greater than 2.In addition, the setting of N can be based on identified pressure release tupe；Tool

Interior water improves the mouthfeel of cooking food.
Based on previous embodiment, the embodiment of the present invention provides a kind of pressure release control method, referring to described in Fig. 2, this method
The following steps are included:
Step 201, household appliance receive pressure release instruction, determine that the pressure release for relief valve handles mould according to preset condition
Formula.
Wherein, preset condition may include the current state of household appliance；For example, preset condition may include it is following at least
One of: the volume and/or weight, household appliance of the substance accommodated in the size of the accommodation space of household appliance, household appliance
The size of remaining space inside.
Here it is possible to the pressure release tupe for relief valve is determined according to the current state of household appliance, the reason is that:
Since household appliance type in the market is different, open ended space size is different inside household appliance, while household electrical appliances are set
The food that standby inside is held occupies the volume inside the household appliance, therefore outside air enters difference during the pressure relief process
Gas volume in household appliance is different, in order to adapt to different demands of the household appliance of different size in pressure release, this
It just needs to determine different relief modes for every kind of different household appliance.
Specifically, household appliance can be according to the accommodation space size inside household appliance, the object that is accommodated in household appliance
The size of the volume of matter and/or the size of weight or household appliance remaining space inside, pressure release time of the setting for relief valve
The times N of the thrust of number or setting adjustment relief valve；Here, the value of N is 3-5 times.Wherein, inside the household appliance
Accommodation space size includes the maximum volume that object can be held inside household appliance；The substance accommodated in the household appliance
The size of volume and/or weight may include: the volume and/or food of the food held inside household appliance in culinary art
Weight；The size of the household appliance remaining space inside may include: the maximum volume that object can be accommodated inside household appliance
Subtract the volume of the food held inside household appliance.
Illustratively, if the accommodation space inside household appliance is larger, the settable pressure release number for relief valve is more
Or the times N of the thrust of setting adjustment relief valve is 5；If household appliance remaining space inside is smaller, it may also set up to be directed to and let out
The pressure release number of pressure valve it is less or setting adjustment relief valve thrust times N be 3.
Step 202, household appliance are based on pressure release tupe, determine that the current thrust magnitude of relief valve is the first thrust magnitude.
Wherein, household appliance is based on pressure release tupe and executes pressure discharge operations, and obtains the current thrust magnitude of relief valve, really
Thrust magnitude before settled is the first thrust magnitude.
Under normal circumstances, household appliance is vacuum state inside household appliance, pressure release is tight-lipped at this time during the cooking process
It closes, i.e., the thrust magnitude of relief valve is maximum value；When household appliance receive pressure release instruction after, start pressure release, then currently
Thrust magnitude remain as maximum value.Therefore, the first thrust magnitude is maximum value.
Step 203, household appliance carry out pressure release within a preset time, according to the first thrust magnitude control relief valve.
Wherein, preset time can be 50-200ms, and preset time here can be carried out according to desired pressure release total duration
Adjustment；Illustratively, if the pressure leak process of household appliance is completed in expectation quickly, then setting preset time can be 50ms.
Here, preset time can be what household appliance was pre-set, can also be set according to the expectation of user.
Step 204, household appliance carry out n-th adjustment to the first thrust magnitude according to predetermined manner, obtain the (n+1)th thrust
Value so that (n+1)th thrust magnitude for relief valve is directed to the thrust magnitude of relief valve lower than n-th, and within a preset time, is pressed
Pressure release is carried out according to the (n+1)th thrust magnitude control relief valve.
Here, n is positive integer, n=1,2 ..., N-1；N is time of the thrust of the adjustment relief valve determined in step 201
Number.Predetermined manner can be preset ratio；Accordingly, it can be adjusted according to thrust magnitude of the preset ratio to relief valve；Example
Such as, thrust magnitude adjusted can be pushed forward the 85%-95% of force value every time for adjustment.
It should be noted that being every time based on last adjustment to the adjustment of relief valve thrust magnitude in step 204；In
Every time after adjustment thrust magnitude, require to carry out pressure release according to thrust magnitude adjusted control relief valve within a preset time.
Illustratively, when adjusting the times N of thrust of relief valve is 3, step 204 can be with are as follows:
The 1st adjustment is carried out to the first thrust magnitude according to preset ratio, obtains the 2nd thrust magnitude, and within a preset time, press
Pressure release is carried out according to the 2nd thrust magnitude control relief valve；
The 2nd adjustment is carried out to the 2nd thrust magnitude according to preset ratio, obtains the 3rd thrust magnitude, and within a preset time, press
Pressure release is carried out according to the 3rd thrust magnitude control relief valve.
Step 205, when n be N when, household appliance adjustment relief valve thrust magnitude be reduced to zero so that household appliance solution
Except vacuum state.
Wherein, when n value is N, last time adjustment is carried out to the thrust magnitude of relief valve；N-th adjusts relief valve
After thrust, the thrust magnitude of relief valve is made to be reduced to zero, at this moment pressure relief opening fully opens, and household appliance releases vacuum state.

Number.Predetermined manner may include preset ratio；Accordingly, pwm signal duty ratio can be adjusted according to preset ratio；Example
Such as, duty ratio is reduced into 5%-15% every time.Here, the duty ratio of pwm signal is reduced, it is meant that reduce pwm signal at one
Ratio shared by high level signal in period；Reduce ratio shared by high level signal in the period, that is to say, that reduce relief valve
Size of current in the conductive group coiling of middle electromagnet exterior, so that electromagnet magnetic force reduces.It is to be understood that reducing
The duty ratio of pwm signal is equal to the thrust magnitude for reducing relief valve.
It should be noted that being every time based on last adjustment to the adjustment of the duty ratio of pwm signal in step 304；
After the duty ratio of adjustment pwm signal every time, require to export corresponding pwm signal within a preset time to control relief valve
Carry out pressure release.
