Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As shown in fig. 1 and fig. 2, an embodiment discloses a temperature control method, including the following steps:
s10, acquiring the temperature of the boiler 100;
s20, comparing the temperature of the boiler 100 with a predetermined temperature, and controlling the operating state of the water pump 200, wherein:
s21, when the temperature of the boiler 100 is higher than or equal to a first preset temperature, the water pump 200 is started, water is sequentially conveyed to the boiler 100 at a first pump speed and a second pump speed for generating steam to be input into the inner container 300, and the second pump speed is lower than the first pump speed;
s22, when the temperature of the boiler 100 is lower than or equal to a second predetermined temperature, the water pump 200 is turned off, and the second predetermined temperature is lower than the first predetermined temperature.
The temperature control method can acquire the temperature of the boiler 100 and compare the temperature of the boiler 100 with a preset temperature, wherein when the temperature of the boiler 100 is higher than or equal to a first preset temperature, the water pump 200 is started to convey water to the boiler 100, steam can be generated and input into the liner 300, the temperature of the boiler 100 can be reduced, and the generated steam temperature is prevented from being too high, when the temperature of the boiler 100 is lower than a second preset temperature, the second preset temperature is lower than the first preset temperature, the water pump 200 is closed at the moment, the temperature of the boiler 100 can be raised again, the generated steam temperature is prevented from being too low due to the too low temperature of the boiler 100, therefore, the service life of the boiler 100 can be prevented from being influenced by the too high temperature of the boiler 100 by controlling the starting or closing of the water pump 200, the temperature of the steam is controlled, and simultaneously, when the water is conveyed to the boiler 100 by the water pump 200, the higher first pump speed is used for rapidly controlling the temperature of the boiler 100, prevent that the temperature of boiler 100 from continuing to rise by a wide margin, also can prevent to generate the steam of high temperature, send water with lower second pump speed again, can slow down boiler 100's cooling rate, prevent that boiler 100 from cooling down too fast to provide the steam of longer time and be used for the culinary art, can further control boiler 100's temperature, make boiler 100 can output the stable steam of temperature, and improve the culinary art effect.
Specifically, when the temperature of the boiler 100 is higher than or equal to a first predetermined temperature, the water pump 200 pumps for a period of time at a first pump speed and then decelerates to a second pump speed.
Alternatively, the first predetermined temperature and the second predetermined temperature are both higher than 100 ℃, and when the water pump 200 feeds water into and through the boiler 100, high-temperature steam is generated to enter the inner container 300, so as to increase the temperature in the inner container 300 for steaming food.
Alternatively, in the above temperature control process, the boiler 100 is continuously in the temperature-increasing state.
Optionally, the first predetermined temperature and the second predetermined temperature may be fixed values or range values, wherein the first predetermined temperature and the second predetermined temperature may be set correspondingly according to requirements.
In one embodiment, the water pump 200 is turned on to sequentially deliver water to the boiler 100 at a first pumping speed and a second pumping speed, and the method specifically includes the following steps:
the water pump 200 is turned on and delivers water to the boiler 100 at a first pump speed;
when the temperature of the boiler 100 is higher than the first predetermined temperature and the difference between the temperature of the boiler 100 minus the first predetermined temperature is less than or equal to the deceleration temperature, the water pump 200 delivers water to the boiler 100 at the second pumping speed.
When the difference between the temperature of the boiler 100 and the first predetermined temperature is less than or equal to the deceleration temperature, it indicates that after the water pump 200 delivers water to the boiler 100 at the first pump speed, the temperature of the boiler 100 is controlled and does not rise continuously, at this time, the water pump 200 can decelerate to the second pump speed, and by reducing the pump speed, the deceleration of the temperature of the boiler 100 can be slowed down, so as to prevent the steam generation time from being short due to the too fast temperature drop of the boiler 100, which affects the cooking of food, and at the same time, the temperature difference of the steam output by the boiler 100 in a certain time can be prevented from being too large, so that the steam with stable temperature can be output, the temperature distribution of the steam in the inner container 300 is uniform, and the improvement of the cooking effect is facilitated.
Since the boiler 100 is continuously heated before and after the water pump 200 delivers water, when the water pump 200 begins to deliver water into the boiler 100 at the first pump speed, the temperature of the boiler 100 does not immediately drop below the first predetermined temperature, but continues to rise, but the temperature of the boiler 100 can be inhibited from continuously rising by delivering water into the boiler 100 at the first pump speed, so that the temperature of the boiler 100 is higher than the first predetermined temperature, but the difference between the temperature of the boiler 100 and the first predetermined temperature can be controlled within a certain range, and at this time, steam with too high temperature generated by too high temperature of the boiler 100 can be prevented from affecting the performance and cooking effect of the boiler 100.
In one period, the boiler 100 is heated up to reach or be higher than a first preset temperature from low temperature, then the water pump 200 delivers water to the boiler 100 at a first pump speed, the temperature of the boiler 100 is firstly continuously increased, then the temperature of the boiler 100 is decreased, at the moment, the temperature of the boiler 100 is still higher than the first preset temperature, when the temperature of the boiler 100 is decreased to be smaller than or equal to a cooling speed of the first preset temperature, the pump speed of the water pump 200 is decreased to a second pump speed, the temperature of the boiler 100 is continuously decreased, and until the temperature of the boiler 100 is lower than a second preset temperature, the water pump 200 is closed. Although the temperature of the boiler 100 is still higher than the first predetermined temperature when the water pump 200 delivers water to the boiler 100 at the second pumping speed in the above-described period, the water is already delivered into the boiler 100 at this time, and the determination condition when water is delivered to the boiler 100 at the first pumping speed is no longer satisfied.
Alternatively, the water pump 200 delivers water to the boiler 100 at a second pump speed when the temperature of the boiler 100 is higher than the first predetermined temperature and the difference between the temperature of the boiler 100 minus the first predetermined temperature is less than or equal to the rundown temperature for a predetermined time. Wherein the predetermined time is greater than 0 s. At this time, it is ensured that the temperature of the boiler 100 is stabilized within a certain range, and it is prevented that the temperature of the boiler 100 is suddenly changed to cause a difference between the temperature of the boiler 100 and the first predetermined temperature to be less than or equal to the deceleration temperature, but the temperature of the boiler 100 is increased again after the water is supplied to the boiler 100 at the second pump speed, thereby reducing errors.
In one embodiment, the ramp down temperature is from 15 ℃ to 25 ℃. When the falling speed temperature is above-mentioned temperature range, the temperature of boiler 100 can not be too high, simultaneously along with the pump speed falls for the second pump speed, can slow down boiler 100's cooling rate to continuously provide the comparatively suitable steam of temperature.
Alternatively, the ramp down temperature is 20 ℃. At this time, the boiler 100 is operated at a proper temperature, and the water pump 200 is decelerated to supply steam for a long time.
In one embodiment, the second pump speed increases as the difference between the temperature of the boiler 100 minus the first predetermined temperature increases. The second pump speed is associated with a difference between the temperature of the boiler 100 and the first predetermined temperature, so that the temperature of the boiler 100 can be adaptively adjusted, the second pump speed is higher when the temperature of the boiler 100 is higher, and the second pump speed is lower when the temperature of the boiler 100 is lower, so that the temperature of the boiler 100 is stably changed, and the temperature of the boiler 100 is prevented from dropping too fast, and stable-temperature steam can be continuously output for a long time.
Optionally, the second pump speed has an initial value, the initial value is smaller than the first pump speed, and the second pump speed is turned off when the temperature of the boiler 100 is decreased to the first predetermined temperature and then decreased to the second predetermined temperature.
In one embodiment, the first pump speed is the highest pump speed of the water pump 200. At this time, the water pump 200 is operated at full power to rapidly control the temperature of the boiler 100, prevent the boiler 100 from being overheated, reduce the time for outputting steam of an excessively high temperature, and improve the cooking effect.
In other embodiments, the first pump speed may also be set by the operator.
In one embodiment, before obtaining the temperature of the boiler 100, the method further includes the following steps:
acquiring the temperature in the liner 300;
when the temperature in the inner container 300 is lower than the set target temperature, the boiler 100 is heated.
By acquiring the temperature of the inner tub 300 and comparing it with a predetermined target temperature, when the temperature in the inner tub 300 is lower than the set target temperature, steam can be generated to increase the temperature in the inner tub 300 by heating the boiler 100 and then the water pump 200 delivers water into the boiler 100.
Alternatively, the set target temperature may be a fixed value or a range value, wherein the set target temperature may be set according to the food to be cooked.
Alternatively, when the temperature in the inner bladder 300 is lower than the set target temperature, the boiler 100 is operated at the maximum power and is warmed up. At this time, the temperature can be rapidly increased, so that the steam can be output as soon as possible to raise the temperature of the inner container 300 and prevent the food from being cooled.
In other embodiments, the boiler 100 may be independently controlled, that is, the temperature in the inner container 300 is not acquired and determined, the boiler 100 is directly controlled to increase the temperature when food steaming is required, and then the temperature in the boiler 100 is compared with the first predetermined temperature and the second predetermined temperature, so that the water pump 200 is turned on or off to deliver steam with stable temperature to the inner container 300.
In one embodiment, after the water pump 200 is turned off when the temperature of the boiler 100 is lower than the second predetermined temperature, the method further includes the following steps:
the above process is repeated until the temperature in the inner container 300 is equal to or higher than the set target temperature, the boiler 100 stops heating and the water pump 200 is turned off.
The water delivered by the water pump 200 is heated into steam through the boiler 100 and is delivered into the inner container 300, the temperature of the inner container 300 can be continuously increased, when the temperature of the inner container 300 reaches a preset target temperature, the boiler 100 and the water pump 200 can be closed, the temperature in the inner container 300 is controlled to be close to the preset target temperature, the steaming temperature of the temperature is provided, the cooking effect can be improved, the energy consumption is reduced, and the energy-saving and environment-friendly effects are achieved.
In one embodiment, when the temperature in the inner container 300 is lower than the set target temperature, a first temperature rise stage is entered, and the heating tube in the inner container 300 generates heat;
when the temperature in the inner container 300 is equal to or higher than the set target temperature, the first temperature maintaining stage is entered, and the heating tube in the inner container 300 is closed.
When the temperature in the inner container 300 is lower than the predetermined target temperature, the temperature of the inner container 300 can be increased by using the steam generated by the boiler 100, and the heating tube in the inner container 300 can be opened to generate heat to increase the temperature of the inner container 300 in a coordinated manner, so that the temperature rise process in the inner container 300 is quicker, and the food is prevented from being insufficiently cooled or heated, and when the temperature in the inner container 300 is higher than or equal to the predetermined target temperature, the heating tube in the inner container 300 is closed, so that the temperature in the inner container 300 is kept stable, and the energy consumption is reduced.
In addition, when the temperature of the boiler 100 is higher than a third predetermined temperature, a difference value of the third predetermined temperature minus the first predetermined temperature is greater than a guard temperature, and the guard temperature is higher than the deceleration temperature, the boiler 100 may be turned off. At this time, the temperature of the boiler 100 is too high, which indicates that a problem occurs in water delivery to the boiler 100, and may be water shortage or damage to the water pump 200, so that the boiler 100 is shut down first, dry burning or safety accidents of the boiler 100 are prevented, and the reason is convenient to investigate.
Alternatively, during the first temperature maintenance phase, the duty cycle of the boiler 100 operation during a fixed period may be calculated by a temperature pid (process Integral differential) algorithm. The working time of the boiler 100 is set more reasonably and more energy-saving.
In one embodiment, when the first temperature-raising stage is started, the upper heat-generating tube and the lower heat-generating tube in the inner container 300 generate heat simultaneously;
or, the upper heating tube or the lower heating tube in the inner container 300 heats;
or, the upper heating tube and the lower heating tube in the inner container 300 alternately generate heat.
The inner container 300 is provided with an upper heating tube and a lower heating tube which are respectively positioned at the upper side and the lower side, and different heating modes can be selected according to requirements, so that at least part of the heating tubes work at the same time, and the inner container 300 is heated.
In one embodiment, before obtaining the temperature of the boiler 100, the method further includes the following steps:
acquiring the temperature in the liner 300;
when the temperature of the inner container 300 is higher than the preset temperature range, entering a cooling stage, and closing the heating pipes in the boiler 100 and the inner container 300;
when the temperature in the inner container 300 is lower than the preset temperature range, entering a second temperature rising stage, rising the temperature of the boiler 100, and heating the heating tube in the inner container 300;
when the temperature in the inner container 300 is within the preset temperature range, the second dimension temperature stage is entered, the boiler 100 is heated, and the heating tube in the inner container 300 is closed.
According to the temperature difference in the inner container 300, the inner container 300 can also enter a cooling stage, a second heating stage or a second temperature-measuring stage respectively, wherein if the temperature in the inner container 300 is within a preset temperature range, the heating tube in the inner container 300 is closed, the inner container 300 is heated only by the mode that the boiler 100 delivers steam to the inner container 300, the temperature rise is gentle at the moment, and the inner container 300 can be kept within the preset temperature range for a long time, so that a stable cooking environment is provided.
The first temperature rise stage or the first dimension temperature stage is judged to be one cooking mode, and the temperature fall stage, the second temperature rise stage or the second dimension temperature stage is judged to be another cooking mode, which can be selected according to the requirement.
