During rapid cooling, one be pressure cooker while cooling, the heat dissipated needed is bigger, thus need
Air pump is wanted to have certain flow;In addition, air pump is to overcome the pressure of electric pressure cooking saucepan to realize cooling in the case where certain flow
Work.But aforesaid way can bring two problems, one be when the unsmooth blocking of pressure cooker exhaust system or failure, air pump
Load increases, and will increase the pressure of pressure cooker cavity and air pump is caused to damage.Unsmooth general exhaust system is blocked by gas outlet
Or the blockings such as pressure limiting valve or loading line blocking cause.
Air pump hypertonia in order to prevent causes air pump easily damaged, and the technical solution of the embodiment of the present application five is in air pump
Added downstream relief valve, when hypertonia, air pump pressure is maintained within the scope of one by relief valve, air pump is avoided to damage
Or pressure cavity pressure is excessive.
As shown in fig. 7, the electric pressure cooking saucepan of embodiment five includes interior pot 9, cooking cavity 8 is formed in interior pot 9, food materials 10 accommodate
In cooking cavity 8.Electric pressure cooking saucepan further includes exhaust outlet 1, air inlet 2, check valve 3, inlet channel 4, air pump 5, relief valve 14
With pot cover 7.Limited valve is set at exhaust outlet 1.
The working principle of embodiment five is as follows:
When using the pressure exhaust type of cooling, due to being to pour air to product cooking cavity 8 using air pump 5, then lead to
It crosses exhaust outlet 1 and the heat of the food materials 10 in cooking cavity 8 is discharged into atmosphere.While cooling, using air in cooking cavity 8
Flowing, inhibit in pot 9 pressure rapid decrease, steadily discharge heat, reach what 10 fast cooling of food materials in interior pot 9 depressurized
Purpose.But air pump 5 needs to overcome at work the pressure of interior pot 9, and needs certain flow, is just able to achieve effect above-mentioned
Fruit, so, usually we 5 pressure value of air pump be much larger than product operating pressure.In addition, in the work of air pump 5, if access
The air row for being blocked or being added cooking cavity 8 does not go out or because blocking is slower, will result in 8 pressure mistake of cooking cavity
Height brings certain risk.Meanwhile under the high load of air pump 5, gas can not be discharged, and the service life greatly shortens, therefore, in air pump 5
Leading portion increases a relief valve 14, by the control of air pump pressure within the scope of one, avoids because of abnormal bring unfavorable factor.
In embodiment five, the downstream of air pump 5 is arranged in relief valve 14, also, pressure release branch is connected on inlet channel 4
Road, specific pressure release branch are arranged between check valve 3 and air pump 5, and relief valve 14 is arranged on pressure release branch road.
About relief valve and safety, the mechanical forced that embodiment five is related to is protected, only a kind of scheme realized.As
One skilled in the art will appreciate that can also realize that pressure release guarantees safety by other means.It can also use and air pump electric current is become
The monitoring of change realizes that air pump pressure exceeded rear (pressure is higher, and load is bigger, and air pump electric current is bigger) stops working.
Existing electric pressure cooking saucepan can be programmed to realize that the slow interval of electric pressure cooking saucepan is vented after the completion of use,
Since culinary art pressure and boiling temperature are at corresponding relationship, to avoid causing in pressure cooker cavity since pressure quickly declines
The boiling for cooking food materials prevents food materials or foam from spraying.
The application is cooling by air, and air is poured into electric pressure cooking saucepan cavity, by the intracorporal heat of chamber, passes through air pair
Except stream discharge cavity, to realize the reduction of pressure and temperature in cooking cavity, achieve the purpose that Rapid opening.But by
Pressure when pressure cooker work is generally in 20-100KPA, the trend of subsequent oriented higher pressure development.When using electric pressure cooking saucepan
Cook congee or similar food materials, and cook pressure it is higher when, a large amount of heat can be gathered inside food materials, therefore, it is desirable in the short time
It is interior that the temperature of electric pressure cooking saucepan is dropped into the degree that can be uncapped, also there is relatively high requirement for the flow of air pump, it is unloaded
Flow > 5L/MIN.
Therefore, it is necessary to during the exhaust of electric pressure cooking saucepan Quick-pressing, air pump not only needs to overcome in pressure cooker cavity
Pressure, be just able to achieve normal work.Meanwhile we also need air pump to have enough flows under the situation of pressure.From production
The economy point of product considers that the air pump for meeting this requirement is at high cost, and size is bigger, and under high load, for air pump
Aging effects are also very big.
The technical solution of embodiment six and embodiment seven efficiently solves the above problem, for some high pressures (such as
Operating pressure > 70KPA) heating container, embodiment six uses the concatenated mode of air pump, and embodiment seven expired using air pump parallel connection
Foot requires.Certainly, it in embodiment not shown in the figure, can according to need while using multiple air pumps in parallel and serial.
As shown in figure 8, the electric pressure cooking saucepan of embodiment six includes interior pot 9, cooking cavity 8 is formed in interior pot 9, food materials 10 accommodate
In cooking cavity 8.Electric pressure cooking saucepan further includes exhaust outlet 1, air inlet 2, check valve 3, inlet channel 4, concatenated two air pumps 5
With pot cover 7.Limited valve is set at exhaust outlet 1.
As shown in figure 9, the electric pressure cooking saucepan of embodiment six includes interior pot 9, cooking cavity 8 is formed in interior pot 9, food materials 10 accommodate
In cooking cavity 8.Electric pressure cooking saucepan further includes exhaust outlet 1, air inlet 2, check valve 3, inlet channel 4, two air pumps 5 in parallel
With pot cover 7.Limited valve is set at exhaust outlet 1.
The working principle of embodiment six and embodiment seven is as follows:
When food materials 10 terminate being made of to cook in closed cooking cavity 8 pot cover 7 and interior pot 9, Quick air-discharge is needed to open
It covers or needs to increase heating frequency, under the situation for shortening cooking time, at this time, it may be necessary to by us by exhaust in cooking
By air inlet 2, check valve 3, external cold air is filled with closed cooking cavity by the system that inlet channel 4 and air pump 5 form
8 (need to overcome airtight cavity pressure) are quickly logical in the state that closed 8 pressure of cooking cavity of maintenance is constant or slowly varying
The pressure limiting valve for crossing exhaust outlet 1, takes away outside heat to pressure cooker, so that temperature in closed cooking cavity 8 be reduced, realizes quick
Cooling and quick power-on heating (when temperature is lower than certain value, is begun to warm up).To realize that pressure cooker Rapid opening and shortening are cooked
It prepares food the needs of time.
But when cooking different food materials, the culinary art pressure needed is different, with the raising of culinary art pressure, equally
The heat of the intracavitary food of electric pressure cooking saucepan is substantially improved, and therefore, it is necessary to come in regular hour (uncap time and cooking time)
Realize above-mentioned two target, for air pump, operating pressure and working flow, maximum stream flow will play main function.When
Under same pressure, working flow is bigger, and pressure exhaust cooling effect is better.Need to make flow < 50L/MIN of air pump.By current
Exhaust of electric pressure cooker bore dia is 2.5mm, and when pressure is 100KPA, air mass flow is 50L/MIN or so, if it is greater than this
The pressure of flow, pressure cooker can rise in cooling procedure, to bring danger, the relief valve in embodiment five can be solved
Certainly above-mentioned security risk.Due to, the culinary art pressure of existing pressure cooker is being continuously improved, so, can have at elevated pressures
The air pump of high flow capacity is from cost, size, for noise etc., is not well suited for using on the pressure vessels such as electric pressure cooking saucepan.
Meanwhile in operating on low voltage, it is similarly desirable to increase flow realizes better cooling effect.So in the scheme of embodiment six
Air pump series connection, may be implemented the promotion of pressure, and air pump is in parallel in embodiment seven, and the promotion of flow may be implemented, by series connection and/
Or in parallel air pump is used in mixed way, we can meet the high flow capacity demand under high pressure simultaneously.
Specific air pump can be used alone or be used in mixed way in parallel and serial, needs to consider electric pressure cooking saucepan pressure and cooks
Food materials prepare food to determine;Above-described embodiment six and seven is particularly suitable for operating pressure > 70KPA heating cooking container Quick-pressing row
Air cooling;When above-described embodiment six and seven is used for low pressure < 70KPA heating cooking container, pressure exhaust cooling can be reduced
Time;Technical solution in addition to being suitable for electric pressure cooking saucepan, embodiment six and seven applies also for low-pressure rice cooker.
In order to most seek the rapidity of culinary art, heating power becomes greatly present electric cooker and similar products, still, practical
In use, since food materials are in ebuillition of heated under persistently continuing high flame, a large amount of foam can be generated, to generate asking for overflowing pot
Topic.So our common electric cookers and similar products increase anti-overflow probe, when foam overflows fastly, stop heating or right
Firepower is controlled, the appearance of anti-Spill stopping pan.So, cooking time can be made to extend.
The technical solution of embodiment eight efficiently solves the above problem.The cooking apparatus of embodiment eight is electric cooker.It is real
The electric cooker for applying example eight passes through in heating pours air in cooking cavity, then is discharged into outside, circulation is formed, to reduce culinary art
Food materials generate the temperature of foam in cavity, meanwhile, the impact generated using forced air makes lather collapse, reduces culinary art foam
Generation, realize high flame heating and be not likely to produce the situation of overflowing pot, reduce cooking time, promote culinary art effect.
As shown in Figure 10, the electric cooker of embodiment eight includes interior pot 9, and cooking cavity 8 is formed in interior pot 9, and food materials 10 accommodate
In cooking cavity 8.Electric cooker further includes exhaust outlet 1, air inlet 2, check valve 3, inlet channel 4, air pump 5 and pot cover 7.
The working principle of embodiment eight is as follows:
During the cooking process, pass through air inlet 2, check valve 3, inlet channel 4, the inflation system that air pump 5 forms, to culinary art
Pour outside air in cavity 8, outside air enters cooking cavity 8, after gas shock foam, is discharged from exhaust outlet 1, entire
In the process, the foam that the boiling of food materials 10 generates occurs eliminating and reduce during cooling and pressure change, gas shock,
Prevent the appearance of overflowing pot.Pressure change is: using the pressure difference of air inlet 2 and exhaust outlet 1, being formed with minute-pressure in cooking cavity 8
The cooking environments of power while improving boiling point, reduce cavity temperature, so as to realize that high flame is cooked.
The quantity of exhaust outlet 1 and air inlet 2 is more than or equal to 1, and the operating pressure of cooking cavity 8 is 0-50KPA (opposite pressure
Power).
In the above-described embodiments, cooking apparatus includes the cooling key of food, passes through opening for the cooling key control air pump 5 of the food
It opens.Preferably, the cooling key of food is arranged on control panel, to realize the cooling effect of food.In order to realize better refrigeration

The control method of the cooking apparatus of the application can be adapted for electric pressure cooking saucepan, electric cooker, low-pressure rice cooker, soy bean milk making machine,
The products such as cooking machine, electric cooking pot.
The control method of the cooking apparatus of the present embodiment is used for electric pressure cooking saucepan, and the structure that Fig. 1 shows the electric pressure cooking saucepan is shown
It is intended to.As shown in Figure 1, electric pressure cooking saucepan includes: cooking cavity, inlet channel 4, air pump 5 and exhaust outlet 1.Wherein, cooking cavity
For holding food materials 10, inlet channel 4 is connected to outside cooking apparatus and cooking cavity.Air pump 5 is arranged on inlet channel 4, with
Gas outside cooking apparatus is pumped into cooking cavity.Limited valve, exhaust outlet 1 and cooking cavity are set at exhaust outlet 1
Connection, so that the intracorporal gas of cooking cavity can flow to the outside of cooking apparatus.Cooking cavity is formed in interior pot 9, and air inlet is logical
Road 4, air pump 5 and exhaust outlet 1 are arranged on pot cover 7.
As shown in figure 15, cooking control method the following steps are included:
Air pump 5 is started to work;
Air pump 5 detects the electric current of air pump 5 after starting to work, when the electric current of air pump is greater than the first setting value, issue first
Warning note, the first warning note need to clean, when air pump electric current is greater than the limiting value of setting for prompting user to send blocking
When, the second warning note is issued, the second warning note needs repairing for making cooking apparatus stop working;
When air pump electric current is less than the first setting value, time, the temperature of cooking cavity and air pump are passed through according to cooking information
Electric current at least one state modulator air pump runing time and/or pressure limiting valve exhaust condition;
When at least one parameter in time, temperature and electric current reaches the second setting value, control air pump stops working.
Using the technical solution of the present embodiment, during the cooking process, air pump is controlled as needed and is opened, and real-time detection gas
The electric current of pump, by the electric current of air pump to determine whether breaking down.When judging not break down, i.e., air pump electric current is less than
When one setting value, pass through at least one parameter control in the electric current of time, the temperature of cooking cavity and air pump according to cooking information
The runing time of air pump processed and/or the exhaust condition of pressure limiting valve.Air pump is pressurizeed by injecting into the cooking cavity with pressure
Cold air, and synchronous or thereafter let out heat gas, due to the discharge of heat, food materials surface temperature reduces, on the one hand can
The formation of foam is controlled, still further aspect keeps certain pressure in cooking cavity, passes through intermittent or successional exhaust
Movement can be such that foam in cavity reduces, and pressure declines, so, the frequency of heating can be increased at this time, reduced non-in culinary art
The waiting time is heated, accelerates the cooking process of food materials, can substantially shorten cooking time.To with pressure after culinary art terminates
The cold air of injection pressurization can be realized Rapid opening in cooking cavity.The exhaust condition of pressure limiting valve include lasting exhaust or
Disconnected exhaust or lasting exhaust and interruption exhaust combine.
The control method of the pressure exhaust type of cooling of the application protection, is realized on different product by logical program
Application.
The application's focuses on through the variation to air pump electric current, judgement of the realization to failure, while for control
The control to air pump, pressure limiting valve may be implemented in three kinds of methods --- time, temperature and electric current (pressure).Specially pressure limiting valve can be with
Interruption exhaust or lasting exhaust or both combine.Exhaust valve can be by solenoid valve control, or without solenoid valve when is uncontrolled
System provides the program for needing to control, reaches cooling purpose using the cooking information of product.
The control method of the application is determined according to food materials situation, specifically includes the type, food materials amount, sticky food materials of food materials
Amount.Above-mentioned food materials situation can be selected when using the product by the user on panel, these information is collected according to pre-set programs and obtains the time
The specific time of control methods, that is, pressure exhaust time.
The working principle of cooking control method is as follows:
Using the pressure exhaust type of cooling product in, when culinary art carry out in or after, need by pressurization arrange
Air cooling mode realizes culinary art and anti-overflow, the demands such as uncap.Since air pump is under different pressures load, electric current can change.
Electric current is bigger, and air pump outlet load is bigger, and the pressure needed is bigger.When air pump is opened, pressure limiting valve is opened, and also limited valve mentions
Preceding unlatching is depressured cooking container in advance.
By the judgement to air pump electric current, to determine the integrality of product, when the electric current of air pump 5 is greater than the first setting value
When, it can be determined that, exhaust is unsmooth, there is clogging.When the electric current of air pump 5 is greater than the limiting value of setting, illustrate that pressure limiting valve does not have
There is movement, circuit or electrical part break down, need to repair.
When the electric current of air pump 5 is less than the first setting value of air pump circuit, before the unlatching of air pump 5, product passes through starting
The cooking information that setting program obtains controls the cooling program of entire pressure exhaust to determine, it is preferable that cooking information includes food
The operating pressure of material information, food materials amount information and cooking apparatus.
Specific air pump work, exhaust process can be by the times, and temperature-sensing element, the curent change setting of air pump comes real
It is existing.For example, we control cooling exhaust process by the time, different food materials can be directed to, determine the unlatching frequency for completing this process
Rate, process control, overall time are realized.When using temperature control, we are by air pump and the frequency of exhaust according to temperature
Variation is to determine.Equally, air pump pressure is consistent with current relationship, we can be determined whether by pressure to certain value
Entire cooling procedure is completed, it in this process, can also be by the way of three kinds of mixing.
When cooking information be it is a large amount of or more sticky, when the food materials of blistering, can control air pump and carry out interruption exhaust or hold
The mixed mode of continuous exhaust is quickly cooled down cooling to realize;When cooking information is a small amount of or not sticky, not easy to foaming food materials,
Cooling can be exhausted using continuous mode, so as to reach the quick effect of comparison.
Conventional needle is generally judged using temperature sensing or pressure sensor to the container of pressure and realizes control.But
Pressure exhaust is cooling since there are certain pressure when cavity is cooked, and the operating pressure of air pump is greater than culinary art pressure, so
Cold air can be poured to cooking cavity, realize cooling.While pressurizeing inflation, need to open exhaust or interruption exhaust, interruption
Exhaust is to avoid rapid pressure from declining in order to which air pump supplements cooking cavity pressure, food fierceness boiling, so that food overflows.?
While pressure does not decline to a great extent, using outside air in the convection current of cooking cavity, the heat of cooking food is discharged fast into
In air, in this process, the temperature of temperature sensor judges that the true temperature of food materials exists during hot and cold air
Certain difficulty.When air stream is larger, temperature-sensitive is low, and when air-flow is smaller, temperature-sensitive is high, meanwhile, slowed down under pressure with fastly, all
It will affect the judgement of temperature.And food materials exhaust it is cooling be only surface temperature, when exhaust velocity is slack-off or stops, food
Heat inside material releases, and can make to cook light temperature rapid increase fluctuation, therefore, the factor that whole process influences is too
It is more, it is difficult to control.When using pressure sensor, because of misclosure when pressure exhaust is cooling, there is inflation not only but also has exhaust,
And air flowing, the data of same pressure are not that (when not being filled with gas in pressure vessel, pressure is corresponding temperature with temperature
Corresponding relationship), the same pass that exhaust is controlled using pressure, there are difficulty for open procedure.
For this particularity of pressure exhaust, optimal mode is time control act, it is only necessary to consider pressure when culinary art,
How much are sticky food and food, to determine the pressure exhaust cooling time.And do not have to from complicated air pressure, temperature change parameter and
Other variables find rule, reduce the possibility of erroneous judgement, greatly reduce the complexity of program.
Certainly, as feasible embodiment, the duration of pressure exhaust namely the operating time of air pump can also be by cooking
The intracorporal pressure of chamber of preparing food, temperature change parameter, or controlled by the electric current of air pump.
In the present embodiment, air pump 5 in cooking cavity intracorporal food materials boiling and in cooking cavity there are when pressure to cooking
Prepare food and be filled with cold air in cavity, alternatively, cooking apparatus be in uncap exhaust phase and cooking cavity there are when pressure to cooking
Prepare food and be filled with cold air in cavity, the cold air being filled with pass through exhaust outlet 1 after the intracorporal gas mixing of cooking cavity and be discharged.
