Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flow chart of a method for controlling a tray-type water storage steam generator according to an embodiment of the present invention is schematically shown, and as shown in fig. 1, a first aspect of the present invention discloses a method for controlling a tray-type water storage steam generator, including:
and (3) an equilibrium stage of continuously outputting steam: and calculating the water supply time t1 of the water pump period according to the relation between the volume of the cooking cavity and the flow of the water pump to obtain the preset water amount, and calculating the steam time t2 of continuously outputting steam according to the preset water amount and the power of the heating plate.
Referring to fig. 2, in particular, the balancing phase includes:
s11: and calculating the water supply time t1 of the water pump period and the steam time t2 of the continuously output steam.
S12: the water pump is started, and water is supplied to the heating plate within the water pump period water supply time t 1.
S13: and (3) after the water pump cycle water supply time t1 is reached, the water pump is turned off, and the heating plate continuously heats steam for a time t2 to generate steam.
Suppose the volume of the cooking cavity of the heating plate is V0If the inflow is on the large side, the space of the cooking cavity of the heating plate is reduced, the pressure of steam generated after the water is boiled is increased, partial water can be sprayed out when the steam is sprayed out from the steam port of the cooking cavity, so that the water cannot flow back, the water which can be used for cooking is increased and decreased finally, the water pump stops working after the water pump supplies water for a period t1, and therefore the total volume of the water to be fed is not more than 1/2 of the volume of the cooking cavity, namely V0/2 cooking chamber volume V based on heating plate0The water inlet flow q of the water pump can be determined according to the water inlet flow q of the water pump1And calculating the water pump cycle water supply time t 1.
Recording the preset water quantity when the equipment works as V1Then V is1＝V0/2, because of the preset water volume V1Related to the water pump inlet flow and time, thereforeCan obtain V1＝q1X t1, i.e. V0/2＝q1X t1, so as to obtain the water supply time t1 of the water pump cycle, the preset water quantity and the water inlet flow q of the water pump1The mathematical relationship between the two is as follows: t is t1＝V0·q1/2。
Further, it is necessary to calculate the steam time t2, the process of evaporating water from liquid to gas requires the absorption of heat, the required amount of heat is related to the weight of water and the initial temperature of water, for a preset amount of water, m ═ ρ × V1＝ρ×q1And x t1, according to the thermodynamic principle, the heat required for evaporating a certain mass of water satisfies the formula Q ═ cxm × Δ t, where Q is the heat, C is the specific heat capacity, and Δ t is the temperature change of water from the initial temperature to boiling.
Since the time required for the evaporation of a predetermined quantity of water is dependent on the power P of the heating plate, it can be concluded that the steam time t is the time at which the predetermined quantity of water is converted into steam2Q/P to yield t after work-up2＝C×ρ×q1Xt 1 xDeltat/P, wherein the specific heat capacity of water is 4.2 x 10^ 3J/kg/P, the density of water is 1.0 x 10^3kg/m ^3, the water inlet flow unit of the water pump is ml/min, the delta t is heated to 100 ℃ from the initial temperature of water, the value range of the heating plate power P is 800W-1500W, and the water pump works at a constant flow rate in the invention, so the corresponding q is obtained1For customization, if the pump is operating at variable flow rate, q1Integration, averaging or other forms of substitution may be used and the invention will not be described in detail.
And (3) dry burning control stage: and carrying out dry combustion judgment according to the steam time t2 of continuously outputting steam and the dry combustion early warning temperature, and returning to the balance stage according to a dry combustion judgment result.
Referring to fig. 3, the dry-fire control stage includes:
s21: continuously acquiring the temperature of the heating plate and the working time t3 of the heating plate;
s22: when the temperature of the heating plate is higher than the dry combustion early warning temperature and/or the working time t3 of the heating plate is higher than the steam time t2, the dry combustion stage is judged, and the heating plate stops working and returns to the balance stage.
Under the condition that the calculation of the steam time t2 is accurate, dry burning judgment can be directly carried out according to the steam time t2, namely when the working time t3 of the heating plate is longer than the steam time t2, the dry burning stage is immediately judged, the heating plate stops heating for a certain time, generally 5-15 seconds, the specific value is determined according to the temperature rise condition, then the water pump immediately starts to work, and the water pump returns to the balance stage again.
Because the steam time T2 is calculated according to the preset numerical value, errors are inevitable, and therefore, further accurate control is needed, at the moment, whether the heating plate enters a dry-burning stage is determined according to the temperature of the heating plate, namely, the temperature T of the heating plate rapidly rises after the moisture of the heating plate is evaporated, when the temperature T is higher than 107 +/-3 ℃, the MCU judges that the heating plate is in a dry-burning state, the heating plate stops heating for a certain time at the moment, generally 5-15 seconds, the specific numerical value is determined according to the temperature rise condition, and then the water pump immediately starts to work and returns to the balance stage again.
Need MCU to continue work when relying on heating plate temperature to carry out dry combustion method judgement, all the time all be in the condition that detects heating plate temperature, can cause the wasting of resources, then can also synthesize steam time T2 and heating plate temperature and carry out dry combustion method judgement simultaneously this moment, MCU does not carry out heating plate temperature judgement before heating plate operating time T3 is greater than steam time T2 promptly, heating plate temperature judgement is carried out again after heating plate operating time T3 is greater than steam time T2, when temperature T >107 ℃ +/-3 ℃, MCU judges that the heating plate is the dry combustion method state, the heating plate stops to heat for a certain time this moment, generally be 5 seconds-15 seconds, the temperature rise condition is looked to concrete numerical value decision, the water pump begins work immediately afterwards, get back to the balanced stage again.
For accurate calculation of the steam time, the initial temperature of the water is obtained, because the temperature of the water at normal temperature in summer and winter is different by tens of degrees, which directly reflects the difference of the time spent from the liquid state to the gas state, and the corresponding steam time t2 is also different, so that for further obtaining the initial temperature of the water, the invention also comprises:
a preheating stage: acquiring the initial temperature and/or the ambient temperature of the heating plate, preheating the heating plate to the working temperature in an empty plate state, and then entering a balancing stage.

S101: and calculating the steam time t2 of continuously outputting the steam according to the initial temperature of the liquid.
The bottom of the heating plate is provided with a temperature sensor for detecting the bottom temperature of the heating plate, so that the temperature of the heating plate or the ambient temperature can be approximate to the initial temperature of the liquid. In order to obtain steam quickly, the heating plate is preheated to the working temperature in an empty plate state, the working temperature is set to be 70-80 ℃, namely the heating plate is controlled to start working, and when the temperature of the heating plate is higher than 70-80 ℃, a water pump is started to inject water into the cooking cavity.
The total heat required by the liquid to reach the boiling state can be determined according to the initial temperature of the liquid and the preset water amount, and the steam time t2 is calculated according to the total heat and the power of the heating plate, namely the value of delta t can be determined when the water temperature of the liquid is obtained.
Referring to fig. 6, the present invention further comprises:
a tray drying stage: and controlling the water pump to stop working and the heating plate to intermittently heat until the cooking time is finished according to the cooking remaining time.
When the cooking is about to finish, no matter what operating condition is that water pump and heating plate, MCU controller control water pump stop work immediately, heating plate intermittent heating, the controller gets into dry combustion method stage procedure simultaneously, and when heating plate temperature T >105 ℃ when 3 ℃, the heating plate stop work immediately, cooking utensil accomplishes the work. At the moment, the heating plate is basically in a dry plate state, and even if little moisture exists, the moisture can be slowly evaporated to dryness because the heating plate has the function of waste heat. And (3) cooking at a dry plate stage is about to be finished, in order to avoid overheating of the heating plate, the MCU judges that the dry-burning temperature is slightly lower than the dry-burning early warning temperature at the dry plate stage, and the heating plate is placed to cause too high temperature to cause premature evaporation of water.
Referring to fig. 7, a time-dependent graph of the operating state of the heating plate, the operating state of the water pump, and the temperature of the heating plate is shown, which is helpful for those skilled in the art to understand the present invention in conjunction with fig. 7.
