Embodiment 1
As shown in Figure 1, the control method that water is discharged more than the electric steam box water tank of the present embodiment, comprising the following steps:
S1: the cooking process of electric steam box is opened, a reference value M0 of the current water of cistern assembly is determined, into S2;Specifically, The a reference value M0 of the current water of cistern assembly, be by it is lasting judgement magnet float and tongue tube forming circuit break-make situation come Determining, when circuit is " logical ", determine a reference value M0 of current water, and a reference value M0 is determined by the setting height of tongue tube It is fixed;
S2: start recording pump working time t0, and continue to cook;Specifically, t0 is to determine water in cistern assembly At the end of a reference value M0 to culinary art, the operating time of water pump operation;
S3: judging whether cooking process terminates, if then calculating the remaining water M of cistern assembly and draining pre- needed for remaining water Water discharge time t1 is counted, and enters S4, otherwise returns to S2 step;
S4: opening drainage procedure, and records draining duration t;Specifically, draining duration t is water pump since drainage procedure It is remained in operation by control water pump when drainage procedure is opened to the working time terminated and is in connected state with drain valve, made The remaining water obtained in cistern assembly flows into cavity components by steam generation component, takes full advantage of in cistern assembly as a result, Yu Shui carrys out the temperature of cooling steam generating assembly and cavity, prevents dry combustion method, improves the cooling efficiency of steam generation component, facilitates Improve the service life of steam generation component;S5: when actually draining duration t=t1, drainage procedure terminates, otherwise return step S4.Specifically, discharge program in, water pump at least operation duration be t1, can stop drainage procedure terminating, and switch off the pump and Drain valve.As a result, by the way that remaining water remaining in water tank to be completely exhausted out, the root that bacteria breed and peculiar smell generate is eliminated, is guaranteed The safety of food in cooking process.
As shown in Fig. 2, further, in step sl comprising steps of
S101: culinary art is opened, and is controlled pump working to meet culinary art institute's water requirement, is persistently judged magnet float and tongue tube The channel case of forming circuit, circuit is " disconnected " state at this time;Specifically, injecting the water in cistern assembly before culinary art is opened Amount is greater than a reference value M0, so that position of the magnet float in water tank assembling is higher than the position of tongue tube, to ensure to meet culinary art Program water consumption, and prevent steam generation component from dry-fire condition occur;Because the position of magnet float is higher than the opposite position of tongue tube It sets, so circuit is centainly in " disconnected " state in cooking process starting, it is assumed that water pump is taken out with pump-out per second for the speed of m Water, it is assumed that m=2mL/s;
S102: maintaining culinary art, and the discharge reduction in cistern assembly drives magnet float to move downward;
S103: when magnet float moves downwardly to the setting height and position of the tongue tube, by cutting magnetic induction line, make The magnet float and tongue tube forming circuit are in " logical " state, determine a reference value M0 of the current water of cistern assembly; Specifically, feed back to signal in controller when circuit is in " logical " state, and start to calculate from determining a reference value M0 to cooking Preparing food terminates required duration t0, it is assumed that a reference value M0 of the current water of cistern assembly is 200ml;
S104;Continue to cook, magnet float continues to move downward with discharge reduction, and the circuit is made to be in " disconnected " shape State.
As shown in figure 3, further, in step s3 comprising steps of
S301: cooking process terminates;
S302: according to water pump pump-out m per second, the remaining water of cistern assembly is calculated by formula M=M0-m*t0 Measure M;
S303: the estimated water discharge time t1 needed for drainage procedure is calculated according to formula t1=M/m.It can calculate as a result, The theoretical duration that remaining water M is completely exhausted out, i.e. estimated draining duration t1 needed for drainage procedure.Specifically, working as cooking process At the end of, from a reference value M0 is determined to this process of culinary art end, the operating time of water pump operation is t0, it is contemplated that water discharge time t1 To drain theoretical water discharge time needed for remaining water in cistern assembly.Assuming that t0=60s, then remaining water M=M0-m* in cistern assembly T0=200-2 × 60=80mL, it is contemplated that required water discharge time t1=M/m=40s.Therefore, in drainage procedure, to ensure water Remaining water in box assembly excludes completely, and control water pump real-world operation time t is not less than 40s.
As shown in figure 4, further, in step S5 comprising steps of
S501: when water discharge time reaches estimated draining duration t1, drainage procedure is maintained;
S502: control water pump remains in operation duration △ t, when actually draining duration t=t1+ △ t, terminates drainage procedure, It switches off the pump and control valve, shutdown.Specifically, water pump at least operation duration is t1, i.e. t1=M/m=80 in discharge program ÷ 2=40s, can stop drainage procedure terminating, and switches off the pump and drain valve.
Preferably, in drainage procedure, when draining duration t=t1, continue to drain, control water pump remains in operation duration △ T, a length of t > t1 when making actually to drain.Assuming that increasing water discharge time △ t=2s, then practical water discharge time is 42s.It excludes as a result, The error amount of water a reference value M0 and/or remaining water M in cistern assembly, with ensure will in cistern assembly remaining remaining water it is complete Be expelled in cavity components, eliminate water tank more than the residual water due to breed bacterium or generate peculiar smell etc. food security hidden danger.
