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 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.

Check valve 6 can make the flow direction of air-flow stablize, and prevent air-flow from flowing back in gas supply pipeline 4.Check valve 6 may be used as into Air valve and exhaust valve, and the quantity of intake valve and exhaust valve all can be multiple, to realize preferably control to air-flow.

Cooking space 3 is additionally provided with cooking space gas outlet 71 and outlet pipe for making air-flow leave cooking space 3 7, air-flow can drain into cooking space 3 by plenum system 10, then be discharged outside to atmosphere from cooking space gas outlet 71 again.This Sample is just capable of forming the gas flowing by cooking space 3, and the air-flow of flowing can break the bubble in cooking space 3, simultaneously Also a part of heat can be taken away, so that the temperature in cooking space 3 reduces, plays anti-overflow effect.

Preferably, the micropressure valve or electromagnetism that can be connected to cooking space 3 and ambient atmosphere are also provided in lid 1 Valve.

In the case where micropressure valve is arranged in lid 1, outlet pipe 7 can be a part of micropressure valve, and cooking space Gas outlet 71 is the air inlet for being formed as micropressure valve.Air-flow can be entered in micropressure valve by the air inlet of micropressure valve, then from The gas outlet of micropressure valve is discharged outside to atmosphere.In this case, cooking space gas outlet 71 usually persistently stays open State, to persistently form gas flowing in cooking space 3.Air-flow constantly flows through cooking space 3, constantly takes away heat And break bubble.

Preferably, some structures for enabling to gas exhaust path more tortuous are provided in micropressure valve.For example, minute-pressure The gas passage (such as can be outlet pipe 7) upwardly extended can be set on the lower lid of valve.Meanwhile in gas passage and micro- Between the gas outlet of pressure valve, block reinforcement can also be set.In this way, need to be bypassed after gas enters the cavity of micropressure valve from gas passage Block reinforcement could be discharged from gas outlet.In this way, the setting of micropressure valve is so that form minute-pressure environment, so that culinary art is empty in cooking space 3 Between air pressure in 3 be greater than atmospheric pressure (preferably, cooking apparatus 100 be constructed so that the gas pressure in cooking space 3 in use Power and the difference of atmospheric pressure are 0-50kPa), to improve the boiling point of the liquid in cooking space 3, reduce boiling, while also can Promote cooking quality.

In the case where solenoid valve is arranged in lid 1, cooking space gas outlet 71 is the air inlet of solenoid valve, and outlet Pipeline 7 is then formed as a part of solenoid valve.Air-flow can be entered in solenoid valve by the air inlet of solenoid valve, then from electromagnetism The gas outlet of valve is discharged outside to atmosphere.Preferably, can control solenoid valve closes cooking space gas outlet 71 intermittently, Switch cooking space gas outlet 71 between opening state and closed state.

In this case, when cooking space gas outlet 71 in the closure state, plenum system 10 is into cooking space 3 It supplies gas, and gas can not be discharged, just foring minute-pressure environment in cooking space 3 in this way, (preferably, cooking apparatus 100 constructs Difference to make gas pressure and atmospheric pressure in cooking space 3 in use is 0-50kPa), it improves in cooking space 3 The boiling point of liquid reduces boiling, while can also promote cooking quality；When cooking space gas outlet 71 in the open state, Just gas flowing is formed in cooking space 3.Air-flow constantly flows through cooking space 3, effectively takes away heat and breaks bubble.

By as described above, it will be understood that the cooking apparatus 100 of present embodiment at least may be implemented in following effect At least one: increase the air pressure in cooking space 3, so that the boiling point elevation of the liquid in cooking space 3, thus can mention Liquid boiling is reduced while rising cooking efficiency, it is effectively anti-overflow；It is formed and is flowed by the gas of cooking space 3, gas flows over Heat can be taken away in journey, reduce liquid boiling, it is effectively anti-overflow；Air-flow can impact foam and make bubble collapse, to realize It is anti-overflow.

Certainly, in other unshowned embodiments, can the cooking apparatus 100 to present embodiment deform. For example, the setting of micropressure valve or solenoid valve can be cancelled or replaced using other devices, and otherwise realize to cooking Prepare food space gas outlet open and-shut mode control.

In the present embodiment, the temperature sensing device communicated with control device, temperature-sensitive dress are also equipped at the lower surface of lid The temperature in cooking space 3 (it is appreciated that the temperature is gas temperature or steam temperature in cooking space 3) can be sensed by setting And corresponding sensing temperature value is obtained, sensing temperature value is sent to control device by temperature sensing device, and control device is according to sensing temperature Angle value and control is realized to plenum system 10 and heating device.

Preferably, the first normal temperature value T1 (i.e. first threshold) is prestored in control device and is greater than the first normal temperature The the second normal temperature value T2 (i.e. second threshold) and third normal temperature value T3 (i.e. third threshold value) of value.Control device is matched It is set to and compares sensing temperature value and these normal temperature values, and based on comparing result control plenum system 10 and heating device.

Referring now to figure 17, when cooking apparatus with cook mode work when, control device is based on following principle to plenum system 10 are controlled: when sensing temperature value is less than the first normal temperature value T1, plenum system 10 is standby；When sensing temperature value is greater than Or it is equal to the first normal temperature value T1 and when less than the second normal temperature value T2, plenum system 10 works；When sensing temperature value is big When the second normal temperature value T2, plenum system 10 is standby.

In this way, device (the i.e. plenum system that can take away heat can be suspended when the temperature in cooking space 3 is lower 10) work, to promote heating efficiency；And the temperature in cooking space 3 it is higher when, plenum system 10 work, avoid overflowing Pot.Since plenum system 10 can be anti-overflow, thus heating device can continue to be heated with the internal pot of high-grade firepower, to have There is higher heating efficiency.

Preferably, still under the mode of cooking, when sensing temperature is less than the second normal temperature value T2, control device control Heating device is constantly heated with the internal pot of high tap position firepower, thus guarantee the quality of food, promotion heating efficiency, and by In plenum system 10 presence without because reducing firepower the problems such as overflowing pot；Reach the second normal temperature value in sensing temperature When T2, control device also controls heating device and switchs to low-grade firepower operation or standby, to avoid being burned.At this point, rice is high Temperature gelatinization, to have better mouthfeel.

Since the sensing temperature value that temperature sensing device is sensed actually is possible to and the actual temperature tool in cooking space 3 There is error, and according to the analysis to the error and other factors, the first standard that will preferably can be prestored in control device Temperature value T1 is set as 65 DEG C -70 DEG C, sets 80 DEG C -90 DEG C for the second normal temperature value T2.It is appreciated that working as sensing temperature When value reaches the first normal temperature value T1, the actual temperature in cooking space 3 may be 68 DEG C -69 DEG C；And work as sensing temperature value When reaching the second normal temperature value T2, the actual temperature in cooking space 3 may be 82 DEG C or so.

And under the mode of cooking congee, with reference to Figure 18, control device carries out plenum system 10 and heating device with another principle Control.Specifically, at culinary art initial stage, heating device is heated with high-grade firepower, and plenum system 10 is standby.When temperature sensing device is sensed After the sensing temperature value arrived is greater than or equal to the first normal temperature value T1, the control of heating device and plenum system 10 in control device System is lower to be worked alternatively.During the alternation, heating device is still heated first with the internal pot of high-grade firepower, and When the sensing temperature value that temperature sensing device is sensed is greater than or equal to third normal temperature value T3, heating device is standby, supplies gas The work of system 10 makes gradually to cool down in cooking space 3；Then, the temperature in cooking space 3 is sensed again, when sensing temperature value is small When third normal temperature value T3, plenum system 10 is standby, and heating device restarts work.Preferably, by third standard temperature Angle value T3 is arranged between 80 DEG C -88 DEG C.

Since plenum system 10 can rapidly make cooking space 3 cooling in heating device break-off, thus shorten Gap between two sections of heating processes of heating device, and then entire cooking time can be shortened, it is cooked to also be able to ascend It prepares food quality, so that congee has better mouthfeel.

As shown in figure 19, this application provides a kind of control methods of cooking apparatus.Wherein, cooking apparatus include pot body, Pot cover and air pump.Pot body is to hold cooked food.Pot cover is arranged in pot body.Air pump can be to the cooking cavity of pot body Inside it is filled with air.Control method includes air pump detection-phase, and air pump detection-phase includes:

Step S11: air pump is made to run the first preset duration to inflate into cooking cavity；

Step S12: after air pump runs the first preset duration, if cooking apparatus receives pressure signal, judge air pump It is working properly, if cooking apparatus does not receive pressure signal, judge air pump operation irregularity.

Specifically, in the present embodiment, detect whether air pump works normally by air pump detection-phase, thus after control Continuous cooking process, and then prevent situations such as leading to overflowing pot because air pump operation irregularity occurs generation.

Specifically, above-mentioned upper pressure signal is detected using mode below: being provided with float on pot cover, is worked as pot body When interior pressure is greater than preset value, float is risen by ejection.When the intracorporal pressure of pot is less than preset value, float passes through itself weight Power is fallen.Further, it is provided with magnetic part on float, magnetic induction part (such as tongue tube, hall sensing are provided in pot cover Device etc.).When float is mobile, magnetic part changes relative to the position of magnetic induction part, and then magnetic induction part senses Magnetic field strength change.Whether it is pushed up that judge whether the intracorporal pressure of pot has been above default by judging float Value.

As shown in figure 19, in the technical scheme of this embodiment, before step S11 further include: step S13: will cook Cavity is heated to preset temperature.Specifically, if making air pump work in the lower situation of the intracorporal temperature of pot, due to pot body and pot Sealing ring between lid is not fully sealed, and pressure namely float can not be gone up in pot body to be jacked up.Air pump can not be judged at this time Whether work normally.By the way that cooking cavity is heated to preset temperature, so that there is certain pressure in cooking cavity, but It is that float can not be jacked up at this pressure.After cooking cavity is heated to preset temperature, air pump is made to work.If air pump can It works normally, then normally upper can be pressed in pot body, and detect pressure signal.

Preferably, above-mentioned preset temperature is in the range of 50 degree to 70 degree.The first above-mentioned preset duration at 50 seconds extremely In the range of 70 seconds.Certainly, the adjustment that those skilled in the art can also be adapted to above-mentioned parameter.

As shown in figure 19, in the technical scheme of this embodiment, control method further includes cooking stage, and cooking stage is in gas It pumps detection-phase to carry out later, cooking stage includes:

Step S21: cooking apparatus exhaust is discharged air pump is filled with the intracorporal air of cooking cavity；

Step S22: pot body heats so that the intracorporal pressure of cooking cavity rises to preset pressure；

Step S23: cooking apparatus exhaust, if cooking apparatus judges air pump operation irregularity, cooking apparatus is with first exhaust Mode exhaust, if cooking apparatus judges that air pump is working properly, cooking apparatus is with the exhaust of second exhaust mode.

Specifically, the purpose of above-mentioned step S21 are as follows: due to that can judge each culinary art rank by pressure in cooking process The temperature of section, it is therefore desirable to by the intracorporal pressure-emptying of pot, be joined with preventing from being filled with the intracorporal pressure of cooking cavity by air pump to culinary art Number impacts, and cooking process is caused to control mistake.Specifically, by solenoid valve ejection pressure limiting valve exhaust pipe is vented, And make to be filled with the intracorporal gas discharge of pot by air pump, and make the state for not being in pressure in pot body.

After cooking apparatus exhaust, heating device runs and makes above to press again in pot body, starts cooking stage.

Further, if cooking apparatus judges that air pump operation irregularity namely air pump can not normally be passed through air into pot body, The arc exhaust mode that exhaust velocity can be used relatively slow at this time, namely be vented using first exhaust mode.If using at this time Quick air-discharge will lead to the generation of overflowing pot phenomenon.If cooking apparatus judges that air pump is working properly, exhaust velocity can be used at this time Comparatively faster Quick air-discharge mode, namely be vented using second exhaust mode.

As shown in figure 19, in the technical scheme of this embodiment, first exhaust mode includes: the exhaust of cooking apparatus interval, The second preset duration is spaced between adjacent exhaust.Preferably, the second preset duration is in the range of 12 seconds to 20 seconds.Specifically Ground, in the state of air pump operation irregularity, using interval exhaust exhaust mode can anti-Spill stopping pan, but exhaust velocity compared with Slowly.

As shown in figure 19, in the technical scheme of this embodiment, second exhaust mode includes two ways.It is a kind of are as follows: to cook It prepares food the exhaust of utensil interval, third preset duration is spaced between adjacent exhaust, wherein when third preset duration is default less than second It is long.It is another are as follows: cooking apparatus is persistently vented.That is, cooking apparatus can be using interval exhaust under second exhaust mode Exhaust mode, but interval time is shorter, and then exhaust velocity is also very fast.Cooking apparatus can also be using the side being persistently vented Formula namely exhaust pipe are in the open state always, and exhaust velocity is substantially improved.Under second exhaust mode, air pump is to cooking cavity It is filled with air in body 11, prevents the generation of bubble, the phenomenon that anti-Spill stopping pan occurs, and greatly improves exhaust velocity.

Preferably, the cooking apparatus of the present embodiment is electric pressure cooking saucepan.

In the prior art, pressure cooker is pot inner seal structure, realizes internal pressure by exhaust pipe and pressure limiting valve control It releases, since there are pressure differences inside and outside pot, is easy in exhaust process by other substances are taken out of to exhaust pipe besides the steam in pot Outside, especially as the slop of congee class, in exhaust pipe exhaust process, it is easy to Rice & peanut milk in pot occur and be excluded together with gas To outside pot, there is overflowing pot.

Therefore, existing exhaust process, otherwise be not vented, otherwise eaten with very slow exhaust mode to complete such fluid class The exhaust process of object, process are very slow.

Due to there is pressure in pot, the outer no pressure of pot is super by the air-flow time of exhaust pipe in slop exhaust pressure relief Crossing certain time and certain frequency, then slop can be expelled to outside pot together with steam, to arrange food with steam Out, usually exhaust with solenoid valve pushes 1S to stop the even lower exhaust gear of 15S and be exhausted, with prevent too fast discharge frequency or Too long evacuation time overflows food.

This application provides a kind of control methods of cooking apparatus to be able to solve the above problem.The principle of the control method is such as Under:

By one air pump of increase on pot cover, it is connected in air pump and pot, one-way sealing is pushed in conjunction with solenoid valve and is vented, It is first passed through before solenoid valve pushes pressure limiting valve to be exhausted and is pumped into air in air pump picture pot, carry out solenoid valve again after forming separate layer Exhaust prevents flowing material to be discharged from exhaust outlet so that Rice & peanut milk is separated with exhaust pipe orifice.Achievable Quick air-discharge is uncapped, and Do not occur overflowing pot phenomenon.Save cooking time.Improve pressure cooker working efficiency.

Cooking apparatus is in when uncapping exhaust phase, makes air pump 5 to being filled with the pre- timing of cold air first inside cooking apparatus Between, exhaust ports are not vented within the first predetermined time；Preferably, the first predetermined time between 15 seconds to 25 seconds, in this reality Apply in example is 20 seconds.

Make air pump 5 that operation be exhausted to exhaust ports while being filled with cold air inside cooking apparatus, wherein exhaust behaviour Make the following steps are included:

Interval exhaust, and the intracorporal pressure value of real-time detection cooking cavity are carried out with the first gear,

When pressure value drops to the first preset value, the first preset value be can be set as needed, such as 30KPa, with Two gears carry out interval exhaust, and the exhaust efficiency of the second gear is better than the first gear.Specifically, when the lasting exhaust of the second gear Between be greater than the first gear lasting evacuation time, and/or, the second gear exhaust interval less than the first gear exhaust interval；

When pressure value drops to the second preset value, the second preset value be can be set as needed, such as 20KPa, and second Preset value carries out continuing exhaust until the intracorporal pressure value of cooking cavity is zero less than the first preset value；

When the intracorporal pressure value of cooking cavity is zero, air pump 5 is made to stop working, and it is pre- so that exhaust ports is continued exhaust second It fixes time.Preferably, the second predetermined time is between 3 seconds to 7 seconds.

In the present embodiment, it is passed through after the intracorporal air of cooking cavity forms certain separation layer in pot body by air pump, Solenoid valve starts control pressure limiting valve exhausting and flows out exhaust pipe at this time since the air being pumped into prevents moving up for slop Then there was only steam, food does not overflow, and with gradually decreasing for the increase and pot inner pressure for being pumped into air capacity, being vented gear can also To be gradually increased, can the middle gear exhaust (such as 3 grades, exhaust 2S stops 8S) by be gradually increased to big gear (such as 4 grades, Exhaust 3S stops 5S) finally exhaust is grown until pot inner pressure position zero.Then stop air pump work, while continuing solenoid valve and pushing away pressure limiting valve general Exhaust duct aperture is opened, and so pushes away solenoid valve 5S, it is ensured that no pressure in pot.The gear of exhaust can be arranged according to demand, as long as full Sufficient exhaust efficiency is gradually increased.
