S3: and when the cooking parameter reaches a preset parameter threshold value, controlling the exhaust device to be opened, and controlling the heating device to continue heating the cooking cavity so as to enable the medium replacement part to generate the gaseous first medium.
It can be understood that, in the embodiment of the present invention, when the pressure cooking appliance is used for cooking, an appropriate amount of clean water is firstly poured into the cooking cavity, then the containing part and the medium replacing part are placed into the cooking cavity, so that the water level in the cooking cavity is approximately over the medium replacing part (of course, the water level can be higher than the medium replacing part or lower than the medium replacing part), and then the prepared food material is placed into the containing part.
After the pressure cooking appliance starts to cook, the heating device can be controlled to heat the cooking cavity, cooking parameters such as temperature or pressure of the pressure cooking appliance are detected, when the temperature or the pressure reaches a corresponding preset parameter threshold value, the exhaust device is controlled to be opened, the heating device is controlled to continue to heat the cooking cavity, when water in the cooking cavity boils, a medium replacement part such as a concave part of a containing part in a figure 1 boils to generate a large amount of bubbles (water vapor), the bubbles can gather in the medium replacement part to increase the pressure in the medium replacement part, under the action of the pressure, part of water in the medium replacement part enters the containing part from a through hole in the bottom wall of the containing part, and the other part of water in the medium replacement part enters the containing part from a water channel, a gap and a through hole in the peripheral wall of the containing part, so that the liquid circulation flow is realized, and the scouring and collision of the liquid on food materials are enhanced, the food material is washed and stirred, so that the food material is rolled, the food thickening speed is increased, and the time required by cooking is shortened.
It can also be understood that after the heating device stops heating, the vapor in the medium replacement part is rapidly condensed, the air pressure in the medium replacement part becomes the normal pressure, and the liquid in the containing part flows back to the medium replacement part from the through hole on the bottom wall of the containing part.
From this, through the cooperation of culinary art chamber, the portion of holding and medium replacement portion, repeatedly erode the edible material and collide, play to erode and the stirring effect to the edible material, make the edible material roll for food thickening speed shortens the culinary art required time.
In particular, according to one embodiment of the present invention,
specifically, according to an embodiment of the present invention, when the cooking parameter is a temperature within the cooking cavity, the preset parameter threshold may be a first temperature threshold.
That is, the temperature in the cooking cavity is greater than the first temperature threshold, that is, the cooking parameter reaches the preset parameter threshold, at this time, the exhaust device can be controlled to be turned on, and the heating device continues to heat the cooking cavity.
Wherein the first temperature threshold is less than the boiling temperature of the liquid second medium. The boiling temperature of the liquid second medium may refer to the boiling temperature of the second medium at atmospheric pressure at the location of the pressure cooking device.
As an example, the first temperature threshold may range from greater than or equal to 80 degrees celsius to less than 100 degrees celsius.
Further, in an embodiment of the present invention, when the cooking parameter is a temperature in the cooking cavity, after the exhaust device is opened, the heating device is controlled to continue heating to cause boiling in the cooking cavity, wherein the medium replacement part generates the gaseous first medium when boiling in the cooking cavity occurs.
That is, when the temperature in the cooking cavity reaches the first temperature threshold, the exhaust device is controlled to be opened so that the cooking cavity is communicated with the atmosphere before boiling occurs, and after the exhaust device is opened, the heating device is controlled to continue heating so that boiling occurs in the cooking cavity, so that the medium replacement part generates the gaseous first medium.
It can be understood that for non-pressure cooking, after the cooking is started, the heating device can be controlled to heat the cooking cavity, the temperature in the cooking cavity is detected, when the temperature in the cooking cavity reaches a first temperature threshold value, the exhaust device can be controlled to be opened, so that the exhaust device is opened before boiling occurs in the cooking cavity, positive pressure can be prevented from being generated in a pot, the heating device can be continuously heated, water in the cooking cavity can be heated to boiling, meanwhile, water in the medium replacement part is boiled to generate steam, the pressure intensity in the medium replacement part is increased, under the action of the pressure, part of water in the medium replacement part enters the containing part from through holes in the bottom wall of the containing part, and the other part of water in the medium replacement part enters the containing part from water channels, gaps and through holes in the peripheral wall of the containing part, therefore, the liquid circulation flow can be realized, and the scouring and collision of liquid to food materials are enhanced, the food material is washed and stirred, so that the food material is rolled, the food thickening speed is increased, and the time required by cooking is shortened.
From this, when the non-pressure culinary art, through culinary art chamber, the portion of holding and the cooperation of medium replacement portion, erode eating the material repeatedly and collide, can accelerate hot water thickening speed, shorten the culinary art required time, can also realize the thick fragrant effect of hot water juice like this under the ordinary pressure, and need not to exhaust after the culinary art finishes, need not to wait for uncapping, do not have exhaust noise, reach the effect of uncapping fast and falling the noise.
Specifically, according to another embodiment of the present invention, when the cooking parameter is the pressure inside the cooking cavity, the preset parameter threshold is a first pressure threshold.
That is, the pressure in the cooking cavity is greater than the first pressure threshold, that is, the cooking parameter reaches the preset parameter threshold, at this time, the exhaust device may be controlled to be turned on, and the heating device continues to heat the cooking cavity.
Wherein the first pressure threshold is greater than atmospheric pressure, e.g., 101 kilopascals. As an example, the first pressure threshold value may have a value in a range of greater than 0kpa and equal to or less than 30kpa relative to atmospheric pressure.
It is understood that when the difference between the first pressure threshold and the atmospheric pressure ranges from greater than 0kpa to 30kpa, the cooking is performed under a slight pressure. The micro-pressure control mode can be an electromagnetic valve, and micro-pressure control is realized by changing the current; the valve can be a spring valve, and micro-pressure control is realized by changing the compression amount of the spring; the valve can be a multi-valve body, and micro-pressure control is realized by changing the opening number of the valve.
Further, in one embodiment of the present invention, when the cooking parameter is a pressure in the cooking cavity, when the exhaust device is opened, the pressure in the cooking cavity is controlled to be reduced by the exhaust device, so that boiling occurs in the cooking cavity, wherein the medium replacement part generates the gaseous first medium when boiling occurs in the cooking cavity.
It is understood that for pressure cooking, which may include but not limited to micro-pressure cooking, after the cooking is started, the heating device may be controlled to heat the cooking cavity, and the pressure in the cooking cavity is detected, and as the pressure in the cooking cavity gradually increases, the boiling point of water also increases, and the water does not boil, and when a positive pressure is generated in the cooking cavity, for example, the pressure in the cooking cavity reaches a first pressure threshold, the exhaust device may be controlled to open, so that the pressure in the cooking cavity decreases, the water in the cooking cavity boils due to the pressure change, that is, the water in the cooking cavity boils, and at the same time, the water in the medium replacement portion boils to generate steam, so that the pressure in the medium replacement portion increases, and under the action of the pressure, a part of water in the medium replacement portion enters the holding portion from the through hole in the bottom wall of the holding portion, and another part of water in the medium replacement portion enters the holding portion from the water channel, The clearance with hold the perisporium through-hole entering on the portion perisporium and hold in the portion, from this, can realize that liquid circulation flows to through boiling and the liquid circulation combined action that flows, reinforcing liquid is to the washing away and the collision of eating the material for the hot water thickening speed shortens the culinary art required time.
Therefore, when pressure cooking is carried out, the cooking cavity, the containing part and the medium replacement part are matched, so that the food materials are repeatedly washed and collided, the soup thickening speed can be increased, and the time required by cooking is shortened. Especially, also can reach the fragrant effect of hot water juice under the minute-pressure, and because the pressure value is lower in the culinary art intracavity after the minute-pressure culinary art finishes, the exhaust is short after the culinary art finishes, can realize uncapping fast to reduce the exhaust noise.
According to an embodiment of the present invention, after controlling the exhaust device to be opened and controlling the heating device to continue heating the cooking cavity, the cooking control method of the pressure cooking appliance further includes:
recording the opening time of the exhaust device;
when the opening time of the exhaust device reaches a first time threshold value, the exhaust device is controlled to be closed, and the heating device is controlled to stop heating, so that the gaseous first medium is reduced, and the liquid level in the containing part is lowered.
It is understood that at least a part of the liquid second medium in the holding portion flows back to the medium replacement portion. Wherein the first time threshold is determined based on a time required for the second medium in a liquid state in the medium replacement part to stop being discharged into the containing part, that is, the first time threshold may be determined based on a time required for the water in the medium replacement part to stop entering the containing part.
It can be understood that when the exhaust device is opened, timing is started, when the timing time reaches a first time threshold value, it is indicated that water in the medium replacement part stops entering the containing part, the liquid circulation flow effect is weakened or disappears, at the moment, the exhaust device is closed, the heating device stops heating the cooking cavity, after the heating device stops heating, water vapor in the medium replacement part is rapidly condensed, the air pressure in the medium replacement part becomes normal pressure, and liquid in the containing part flows back to the medium replacement part from a through hole in the bottom wall of the containing part. Therefore, the exhaust device can be accurately controlled to be closed and the heating device stops heating, and the method is easy to realize and does not need to increase hardware.
According to an embodiment of the present invention, after controlling the exhaust device to be turned off and controlling the heating device to stop heating, the cooking control method of the pressure cooking appliance further includes:
recording the time for stopping heating of the heating device;
and when the time for stopping heating of the heating device reaches a second time threshold, controlling the heating device to heat the cooking cavity again, and controlling the exhaust device to be opened again.
Wherein the second time threshold is determined based on a time required for the liquid-state second medium in the containing section to stop flowing back to the medium replacement section. That is, the second time threshold may be determined based on the time required for the water inside the containing section to stop flowing back to the medium displacing section.
It can be understood that when the exhaust device is turned off, i.e. the heating device stops heating, the timing is started, and when the timing time reaches the second time threshold, the water in the containing part is indicated to have fallen back to the medium replacement part, and at this time, the heating device can be controlled to heat the cooking cavity again. Therefore, the reheating device can be accurately controlled to reheat, and the method is easy to realize and does not need to increase hardware.
It should be noted that, when the exhaust device is controlled to open and close the heating device again to heat, the heating device may be controlled to heat the cooking cavity again and the exhaust device may be controlled to open again, or the heating device may be controlled to heat the cooking cavity again and the exhaust device may be controlled to open again.
For example, when the cooking parameter is the temperature in the cooking cavity, the exhaust device is controlled to be opened while the heating device is controlled to heat the cooking cavity; when the cooking parameter is the pressure in the cooking cavity, the heating device is controlled to heat the cooking cavity until the pressure in the cooking cavity rises to a first pressure threshold value, and the exhaust device is controlled to be opened when the pressure in the cooking cavity rises to the first pressure threshold value.
That is to say, when the culinary art parameter is the temperature in the culinary art intracavity, when exhaust apparatus closed heating device stop heating promptly, the timing begins, the liquid that holds in the portion at this stage flows back to medium replacement portion from the diapire through-hole that holds a diapire, when the timing time reaches the second time threshold value, judge that the water that holds in the portion stops to flow back to medium replacement portion, steerable heating device heats the culinary art chamber again this moment, control exhaust apparatus opens simultaneously, through heating device with the water heating of culinary art intracavity to the boiling, water in the medium replacement portion gets into and holds in the portion, therefore, through liquid circulation flow, eat and place and hold the portion, erode and collide eating the material, make the eating material roll, circulate in proper order, reach the pottage effect.
When the cooking parameter is the pressure in the cooking cavity, when the exhaust device is closed, namely the heating device stops heating, timing is started, liquid in the containing portion flows back to the medium replacement portion from the through hole in the bottom wall of the containing portion at the stage, when the timing time reaches a second time threshold value, the water in the containing portion is judged to stop flowing back to the medium replacement portion, the heating device can be controlled to heat the cooking cavity again at the moment, the pressure in the cooking cavity is detected, when the pressure in the cooking cavity reaches a first pressure threshold value, the exhaust device can be controlled to be opened, the pressure in the cooking cavity is reduced, the water in the cooking cavity boils, the water in the medium replacement portion enters the containing portion, therefore, under the combined action of boiling and liquid circulation flow, the food is placed in the containing portion, the food is washed and collided, the food is rolled, and the food is circulated in sequence, and the thick soup effect is achieved.
According to one embodiment of the invention, for the cooking parameter being the temperature in the cooking cavity, when the total cooking time reaches the preset cooking time, the heating device is controlled to stop heating, the exhaust device is controlled to be closed, and the cooking program is ended. For the pressure that the culinary art parameter is for cooking the intracavity, when the culinary art total time reaches predetermined culinary art required time, control heating device stop heating, control exhaust apparatus opens, and until the gas emission in the culinary art intracavity is accomplished, water stops the boiling, and the steam reduces in the medium replacement portion, holds the liquid in the portion and flows back to medium replacement portion from the diapire through-hole that holds a diapire, holds a liquid level decline, after the gas in the culinary art intracavity is discharged completely, closes discharge valve, the end procedure.
The cooking control method according to the embodiment of the present invention will be described in detail below with respect to both pressureless cooking and pressure cooking.
In the first embodiment, the specific working process of pressureless cooking is as follows:
the user selects the function of making a deep pot hot water fast, begins the procedure of making a deep pot hot water fast, and control heating device heats culinary art chamber for example interior pot, and the temperature of measuring to the culinary art chamber simultaneously monitors. When the temperature in the cooking cavity reaches a first temperature threshold value T0 (the range of T0 is 80-100 ℃), timing T is started, an exhaust device such as an exhaust valve is opened to prevent positive pressure from being generated in the pot, the heating device continues to heat, water in the cooking cavity, namely the inner pot and the containing part, boils, meanwhile water in the medium replacement part boils to generate water vapor, the pressure in the medium replacement part rises, under the action of the pressure, part of water in the medium replacement part enters the containing part from through holes in the bottom wall of the containing part, the other part of water in the medium replacement part enters the containing part from water channels, gaps and through holes in the peripheral wall of the containing part, the liquid level in the containing part rises, and through liquid circulation flow, flushing impact of soup on food materials is achieved, and soup thickening speed is increased. When timing time t reaches first time threshold t0, when the water in the medium replacement part reduces to no longer entering the portion that holds, the liquid circulation flow effect weakens or disappears, stop to cook the chamber heating, close discharge valve simultaneously, start timing t1, steam in the medium replacement part reduces at this stage, the liquid in the portion that holds flows back to medium replacement part from the diapire through-hole that holds a diapire, make the liquid level in the portion that holds descend, when t1 reaches second time threshold t10, heating device restarts the heating, open discharge valve once more, time t simultaneously, water in the medium replacement part gets into once more and holds the portion, liquid circulation flows, make the hot water wash away to the edible material, the striking, circulate in proper order. And when the total cooking time reaches the preset cooking required time t20, stopping the heating device, closing the exhaust valve and ending the program.

When the pressure in the cooking cavity reaches a first pressure threshold value P0 (during micro-pressure cooking, the range of P0 is 0-30KPa), timing t is started, an exhaust device such as an exhaust valve is opened, the pressure in the cooking cavity is reduced, water in the inner pot and the containing part in the cooking cavity boils, meanwhile water in the medium replacing part boils to generate water vapor, the pressure in the medium replacing part rises, under the action of the pressure, part of water in the medium replacing part enters the containing part from a through hole in the bottom wall of the containing part, the other part of water in the medium replacing part enters the containing part from a water channel, a gap and a through hole in the peripheral wall of the containing part, the liquid level in the containing part rises, and through the combined action of boiling and liquid circulation, the flushing impact of soup on food materials is realized, and the soup thickening speed is increased. When timing time t reaches first time threshold t0 water reduces to no longer entering when holding in the portion in the medium replacement portion, the liquid circulation flow effect weakens or disappears, close discharge valve, stop heating the culinary art chamber, start timing t1, steam reduces in the medium replacement portion of this stage, hold the liquid in the portion, flow back to medium replacement portion from the diapire through-hole that holds a diapire, make the liquid level that holds in the portion descend, when t1 reaches second time threshold t10, heating device restarts the heating. When the pressure in the cooking cavity reaches a first pressure threshold value P0, timing t is started, the exhaust valve is opened again, water in the medium replacement part enters the containing part again, and liquid circularly flows to enable soup to wash and impact the food materials and sequentially circulate. When the total cooking time reaches the preset cooking time t20, the heating device stops heating, the exhaust valve is opened until the gas in the cooking cavity is exhausted, the water stops boiling, the liquid in the containing part flows back to the medium replacement part from the through hole on the bottom wall of the containing part, and the liquid level of the containing part is lowered. After the gas in the cooking cavity is exhausted, the exhaust valve is closed, and the program is ended.
