Function other than, can also have the various functions such as cook congee.
As shown in Figure 1, cooker 100 includes cooker body 110 and cover 120.The substantially rounded cuboid of cooker body 110
Shape, and the interior pot incorporating section with cylindrical shape, interior pot 111 can freely be put into interior pot incorporating section or be stored from interior pot
Portion takes out, to facilitate the cleaning of internal pot.Interior pot 111 is usually made of metal material and upper surface has circular open, is used for
Hold material to be heated, rice, soup etc..The heating unit for heating interior pot 111 is generally included in cooker body 110.
The substantially rounded rectangular shape of cover 120, and essentially corresponded to the shape of cooker body 110.Cover 120 with
Pivotable mode is connected to cooker body 110, and cooker body 110 is closed for covering.It has been removably installed in the inside of cover 120 circular
Inner cover 121, for covering the upper surface open of pot 111 in conjunction, to form a relatively closed cooking space.The week of inner cover 121
It encloses and is typically provided with seal member, for avoiding the steam in interior pot 111 when interior pot 111 is covered conjunction by cover 120 from interior pot 111
Outside is leaked between upper surface and cover 120.Inner cover 121 is made of the good metal of heat conductivity.Certainly, inner cover 121
Can be other shapes, and can also be made of other materials, the present invention is not particularly limited this.Also, cover also may be used
To be set as other shapes and structure, as long as it can close cooker body in process middle cover of cooking.In general, it is formed on inner cover 121
It is useful for the steam generated being discharged to the steam (vapor) outlet of the outside of cover 120 in interior pot.
As shown in Figs. 1-2, cooker 100 further includes the water container 130 being arranged in cooker body 110, water container heating unit
140 and steam channel 160.Water container 130 is removeably positioned in cooker body 110, can store to generate
The water of steam.Water container heating unit 140 is arranged on 130 lower section of water container, adds for (being discussed in detail below) if necessary
Thermal capacitance is contained in the water in water container 130, to generate steam.Water container 130 is connected with interior pot 111 by steam channel 160.Steam
Channel 160 includes steam inlet 161, which connects with water container 130, and the steam generated in water container 130 leads to
It crosses steam inlet 161 and enters steam channel 160, be then transported in interior pot 111 via steam channel 160, to prevent interior pot 111
In rice drying, influence mouthfeel.
With reference to figure 2, cooker 100 further includes temperature sensor 150, for detecting the temperature of steam.Applicant have observed that
To accurately control the quantity of steam that inside pot 111 supplements, it is necessary to which when accurate judgement steam, which starts, generates, and accurately detect
Generated quantity of steam.The setting of reasonable set temperature sensor 150 is answered as a result,.If it has been found that by temperature sensor
150 are placed in the lateral surface of water container 130, easy loose contact, cause measurement inaccurate, and can not judge be in water container 130
It is no to have water.If temperature sensor 150 is placed in the exterior bottom of water container 130, due to the floor space of water container 130 itself compared with
Small, temperature sensor 150 can account for the bottom thermal transfer area of larger proportion, be unfavorable for the conduction of heat, and due to bottom space
Limited, temperature sensor 150 is easily by the conduct radiation heat of water container heating unit 140, it is impossible to accurately judge to measure
Temperature whether be water container 130 temperature, cause to judge inaccurate.Therefore, temperature sensor 150 can be set as to sensing steam
Temperature in channel 160 can lead to the temperature rise in steam channel 160 due to the flowing for there was only steam, and work as water container
In 130 during dry combustion method, heat radiation can not be transmitted in steam channel 160, therefore the temperature that temperature sensor 150 detects is steam
Temperature, can accurately reflect when steam starts to generate.
Preferably, temperature sensor 150 is arranged on 130 top of predeterminated position rather than water container in steam channel 160
Steam inlet at, for sensing the temperature in steam channel 160, generate temperature signal, and the temperature signal is passed into control
Device (being hereafter described in detail) processed.As described above, when generating steam in water container 130, steam can pass through steam channel 160
Into interior pot 111, thus the temperature in steam channel 160 inevitably increases due to the circulation of steam.It thus will be warm
Degree sensor 150 is arranged on the time that can more accurately judge that steam is generated in water container 130 in steam channel 160, so as to
Quantity of steam (being discussed in detail below) into interior pot 111 is accurately controlled based on this judgement.
Due to water container 130 may there is a situation where wherein anhydrous dry combustion method, and in the case of 130 dry combustion method of water container,
Its heat radiation generated is also possible to the variation that temperature sensor 150 is caused to detect temperature, in order to avoid temperature sensor 150
The heat radiation erroneous judgement that 130 dry combustion method of water container is generated is the variation of the temperature caused by steam is generated in water container 130,
It is further preferred that as shown in figure 3, the distance between steam inlet 161 and temperature sensor 150 B be more than or equal to 5mm, due to
Steam inlet 161 is connected with water container 130, and therefore, even if dry combustion method in water container 130, the heat radiation generated can not also conduct
To at temperature sensor 150, because without making temperature sensor 150 that erroneous judgement occur.Certainly, those skilled in the art can also
According to actual needs or the distance between steam inlet 161 and temperature sensor 150 B are set as it by the actual size of cooker
Its appropriate numerical value.
Further, which further includes controller (for simplicity, not shown in figure), controller and temperature
Sensor 150 is electrically connected, and is electrically connected with water container heating unit 140, for controlling the heated of water container heating unit 140
Journey, and the temperature signal from temperature sensor 150, the temperature are received in the heating process of control water container heating unit 140

Minute or 20 minutes, those skilled in the art can select suitable numerical value according to actual conditions).
In step s 2, when water container heating unit begins to warm up water container, temperature sensor 150 starts to sense steam
Temperature in channel 160 generates temperature signal and the temperature signal constantly is passed to controller.Due to by temperature sensor
150 are arranged in steam channel 160, and therefore, when generating steam in water container, steam channel can be warm due to the circulation of steam
Degree rises, and the temperature sensor so as to be arranged in steam channel can be accurately sensed the variation of temperature, and can should
The variation of temperature passes to controller in real time.
In step s3, controller receives the temperature signal from temperature sensor 150, and judges that temperature signal is corresponding
Whether variation of the numerical value in unit interval Δ t (such as 15s) be more than the first temperature threshold (such as 55 degree).If it is, into
Enter step S4, controller control water container heating devices heat, and start to steam time of delivery tsTiming.Preferably, steam
Time of delivery tsFor predetermined time T3, such as 5 minutes.Specifically, if some of controller in first time threshold value T1
Time point, such as when reaching the time point of 8 minutes, detect that the numerical value corresponding to temperature signal is dashed forward in unit interval Δ t
It is so second value, such as 80 degree are changed to from 25 degree suddenly in 15s from the first numerical value change, then can determine water container 130
In have water, and water has boiled and generated steam at this time.Based on this judgement, controller control water container heating unit 140 continues to add
Hot predetermined time T3, such as 5 minutes, to spray into quantity of steam 5 minutes corresponding in inside pot.Wherein, in the process, the first temperature
Degree threshold value is used to weigh variation of the temperature corresponding in Δ t in jet chimney, for example, being 55 degree in this embodiment
(it is 80 degree that temperature changes from 25 degree).During controller control water container heating unit 140 heats, if temperature signal
Variation of the corresponding numerical value in Δ t is more than the first temperature threshold, then can determine that has water and generated steaming in water container 130
Vapour.
Preferably, after step s4, step S6 judge steam time of delivery tsBefore whether reaching predetermined time T3, first
Step S5 is performed, that is, judges the total heating time t of this cyclecWhether first time threshold value T1 is had reached.If not, it enters step
S6, if so, illustrating total heating time t of the water container heating unit in this cyclecFirst time threshold value T1 is had reached, at this moment may be used
To stop heating.
In step S6, steam time of delivery t is judgedsWhether predetermined time T3 is reached, if not, being back to step S5, such as
It is then to enter step S7, controller control water container heating unit 140 stops heating, and the time of stopping can be the second time
Threshold value T2, such as 30 minutes.Later, return to step S1 starts subsequent cycle.And so on, until insulating process terminates.It is preferred that
Ground, the time for stopping heating might be less that the second time threshold T2.T2 can be 30 minutes, certain those skilled in the art
T2 can be set as other appropriate numerical value, such as 15 minutes or 20 minutes etc. according to actual conditions.
Step S3 is returned to, if the numerical value corresponding to temperature signal remains unchanged in first time threshold value T1, is controlled
Device control water container heating unit terminates heating, referring to step S8 and S9.Specifically, if in step S8, this cycle always heats
Time tcFirst time threshold value T1 is had reached, and the numerical value corresponding to temperature signal does not mutate (in unit in T1
Variation in time Δ t does not occur more than the situation of the first temperature threshold, i.e. the answer of step S3 is N), then S9 is entered step,
There is no steam generation in judgement water container 130, then water container is probably dry-fire condition, and then controller control water container adds
Thermal 140 terminates heating, in order to avoid damage water container.Subsequent cycle is not also restarted at this time, unless carrying out manual intervention.And such as
Fruit is in step S8, the total heating time t of this cyclecFirst time threshold value T1 has not yet been reached, then is back to step S2, concrete operations
Cheng Shangwen has been described, and details are not described herein.
Controller is according to the temperature that occurs during being heated in first time threshold value T1 to water container heating unit 140
Variation come judge whether to generate in water container 130 steam and water container 130 whether dry combustion method, and based on this judging result come phase
Ground adjustment subsequent heat mode is answered, is more timely controlled it is thus achieved that more accurate to insulating process, prevents heating process
In there is the problems such as dry combustion method, so as to really realize heat preserving mode automation and intelligence.
It is appreciated that those skilled in the art can determine the first temperature threshold according to actual experiment.In addition, putting into practice
In, the numerical value of first time threshold value T1, the second time threshold T2, unit interval Δ t, predetermined time T3 etc. can according to circumstances be set
