With reference to Fig. 1-Fig. 4, triple valve 5 is arranged between water tank 3 and water pump 4, triple valve 5 comprises shared valve port 51, normal open valve port 52 and valve-closed port 53, sharing valve port 51 is connected with pump intake 41, normal open valve port 52 is suitable for communicating with atmosphere, valve-closed port 53 is connected with water outlet of water tank 31, one of them when steam cooking apparatus 100 is worked in normal open valve port 52 and valve-closed port 53 and 51 conductings of shared valve port, that is to say, when steam cooking apparatus 100 for example steam microwave oven when work, in normal open valve port 52 and valve-closed port 53, only there are a valve port and 51 conductings of shared valve port, another valve port and the 51 not conductings of shared valve port.
Wherein, triple valve 5 can be three-way magnetic valve, for example can be arranged in the situation of three-way magnetic valve energising, share valve port 51 and valve-closed port 53 conductings, the 52 inner port sealings of normal open valve port, now share valve port 51 and be communicated with water tank 3, the water in water tank 3 can flow in steam generator 2 by sharing valve port 51 under the effect of water pump 4; In the cold situation of three-way magnetic valve, share valve port 51 and 52 conductings of normal open valve port, valve-closed port 53 inner port sealings, now share valve port 51 and directly communicate with atmosphere, and steam generator 2 cuts off with water tank 3, as shown in Figure 2.Be appreciated that, triple valve 5 can also be the valve of other type, as long as can meet in a period of time water tank 3 and steam generator 2 conductings, in another a period of time by water tank 3 and steam generator 2 cuts off and steam generator 2 communicates with atmosphere within this period function.
Preferably, steam cooking apparatus 100 is cooked the food in cooking cavity 11 in cooking time, cooking time comprises main cooking time and at residual treatment time of water thereafter, in main cooking time, share valve port 51 with valve-closed port 53 conductings so that the water in water tank 3 is fed in steam generator 2, in residual treatment time of water, share valve port 51 with 52 conductings of normal open valve port so that in the residual water inflow steam generator 2 in the pipeline between triple valve 5 and steam generator 2.Here, it should be noted that, main cooking time and residual treatment time of water are continuous in time.Be appreciated that main cooking time can also be discontinuous with residual treatment time of water, can process according to user's real needs the processing time of the residual water in pipeline.
Steam cooking apparatus 100 is when for example steam microwave oven is started working, three-way magnetic valve energising, share valve port 51 and valve-closed port 53 conductings, water in water tank 3 pump intake 41 of flowing through under the suction of water pump 4 by valve-closed port 53, then through pump outlet 42 regular supplies to steam generator 2, heat-generating pipe 21 in steam generator 2 heats the water flowing in steam generator 2, and generating steam, these steam enter in cooking cavity 11 by steam fumarole 111, thereby the food in cooking cavity 11 is cooked.When culinary art arrives certain time point (can obtain with test as calculated) finishing nearly, three-way magnetic valve is stopped power supply in advance, the valve-closed port 53 now communicating with water tank 3 is closed, the normal open valve port 52 that connects atmosphere is connected with the interior water route of system, now, under water pump 4 suction is controlled, the residual water in water route is continued to be expressed in steam generator 2 and is added heat loss because obtain atmospheric pressure from normal open valve port 52.When cooking time finishes, residual water in pipeline is also all pressed in steam generator 2, because steam generator 2 is still in high temperature, these water that are brought into not only can accelerate the cooling of steam generator 2, simultaneously, because the water yield is little, therefore also can evaporate totally under the after-heat of steam generator 2 is supplied with.It should be noted that, " certain time point " refers to the distal point of main cooking time, the head-end of residual treatment time of water.
According to for example steam microwave oven of steam cooking apparatus 100 of the utility model first aspect embodiment, by water pump 4 and triple valve 5 are set, at cooking process latter end, water pump 4 can with normal open valve port 52 conductings that communicate with atmosphere of triple valve 5, thereby the residual water in pipeline can all be pumped to steam generator 2, noresidue in pipeline, and the operation of need not user in this process being correlated with, and then effectively ensured the cleanliness factor in pipeline, and ensure the culinary art effect of steam cooking apparatus 100.
Further, steam cooking apparatus 100 further comprises: controller 6 (can be PCB electric-controlled plate), controller 6 is located on cavity 1, particularly, as shown in Figure 4, controller 6 can be arranged on the upper right side place of cavity 1 front portion, with user-friendly, controller 6 is connected with triple valve 5, the residue cooking time t detecting when controller 6 is less than the shared valve port 51 of residual treatment time of water T Time Controller 6 control and 52 conductings of normal open valve port, that is to say, when the residue cooking time t detecting when controller 6 is more than or equal to residual treatment time of water T, controller 6 is controlled and is shared valve port 51 and valve-closed port 53 conductings, in the time that triple valve 5 is three-way magnetic valve, the power on/off that controller 6 can be controlled three-way magnetic valve realizes one of them and the conducting of shared valve port 51 in normal open valve port 52 and valve-closed port 53, another in normal open valve port 52 and valve-closed port 53 and shared valve port 51 cut off.Here, it should be noted that, " residue cooking time t " refers to the time of the dynamic change that controller 6 detects in real time, and it is the difference of the cooking time of process in the whole cooking time of cooking food and cooking process.
Because determining any fluid, the physical property of fluid all there is viscosity (friction), water is no exception, and also there is friction (being external friction) with the inwall of pipeline in water in flow process, make actual value and the theoretical value of the flow of water in pipeline have error, cause closing after switching at three-way magnetic valve, water pump 4 actual water supplies are less than the theoretical amount of program setting, arrange precisely as far as possible in order to make three-way magnetic valve shift to an earlier date the shut-in time, can set the time that three-way magnetic valve closes in advance becomes a ratio (being weight coefficient) with the product of water pump 4 water supply controlled quentity controlled variables with residual water in pipeline,
In the time that this steam cooking apparatus 100 is specifically set, can automatically calculate the time (being residual treatment time of water T) that three-way magnetic valve is closed in advance according to formula below:
Wherein, the density that ρ is water, d is the internal diameter of the pipeline (being above-mentioned pipeline) between triple valve 5 and steam generator 2, and l is the length of pipe between triple valve 5 and steam generator 2, and Q is discharge, and α is weight coefficient.
As for determining of weight coefficient α, can be according to the suitable empirical value of the concrete setting of actual conditions.Due to weight coefficient α to affect factor a lot, the friction (material by pipeline determines) of for example water and pipeline, water pump 4 send hydraulic thrust, and the humiture of air etc. is all relevant, be difficult to directly obtain by theoretical formula, in practice because ρ, d, l, Q are known numeric value, by selecting the numerical value of different d, l, Q, the t that repeated measurement is corresponding, then considers the empirical value of calculating weight coefficient α.
Then in steam cooking apparatus 100, set in advance fixed weight coefficient α (being empirical value), just can obtain each culinary art according to above-mentioned formula time, close in advance the precise time of three-way magnetic valve.
In addition, the length of why residual treatment time of water T being done enough, can also relax the supply water problem of the cooking cavity 11 temperature upper punches that increase suddenly and cause of in the time that cooking process finishes soon water pump 4.
Preferably, in residual treatment time of water T, the output S of water pump 4 meets:
α×R≤S≤V
Wherein, R is the residual water yield in pipeline, and V is the amount that steam generator 2 is heated into water steam.
In other words, the selection principle of the output S of water pump 4 is: calculate border ideally according to the digestion power of steam generator 2 (being heated into the ability of steam by water), detect the shortest time according to lack of water and choose residual treatment time of water higher limit, calculate desirable lower boundary according to the residual amount in system pipeline afterwards, then use ideal boundary numerical value × weight coefficient α, and the residual water treatment pump water yield used can be the arbitrary value in this scope, be that residual amount × weight coefficient α is to the number range between the maximum digestion water yield of steam generator 2, the closer to the maximum digestion water yield of steam generator 2, residual water treatment must be faster.Be appreciated that in fact and can adjust according to the situation of normal cooking process.
Generally, in order to ensure the processing accuracy of residual water, the output of water pump 4 should meet in residual treatment time of water T, residual water in pipeline all can be pumped in steam generator 2, and there will not be the situation that still remains residual water in pipeline, and steam generator 2 can just in time all evaporate this part residual water, and there will not be steam generator 2 only residual part water to be evaporated, has residual water to remain in the situation in steam generator 2 in addition.Thus, ensure the uniformity (in pipeline without residual water) of states before and after cooking process, reduced for example too much uncertain factor when steam microwave oven of each unlatching steam cooking apparatus 100, improved control accuracy, and reduced the energy consumption of water pump 4.
Wherein, water pump 4 can be selected the direct current extrusion pressing type water pump that noise is relatively little, this water pump size is minimum all more than 200ml/min, the measured data of form be below based on specified output be 320 ± 80ml/min (always energising situation under, this water pump output per minute is 240ml～400ml) this water pump on.In description below the application, describe as an example of the water pump of above-mentioned specification example.
Wherein, the temperature of steam generator 2 when 40 DEG C in above table～100 DEG C, 110 DEG C are closed for three-way magnetic valve pipe.
Because the output of water pump 4 is generally all larger, and the power of steam generator 2 cannot digest (evaporating completely) so many outputs conventionally, for example, within 1min, the steam generator 2 of 900W can only digest at most the water of 20.8ml, water by 20.8ml flashes to steam completely, so just requiring water pump 4 maximums can only work being no more than in this standard of 20.8ml/400ml=0.05, and this just means, if water pump 4 is using 1 second as the work of cycle repetition break-make, its time of connecting can not be greater than 0.05 second in 1 second, otherwise, steam generator 2 digests and does not come.
So, when residual water treatment, how many according to the residual water yield of pipeline, be under prerequisite in the disposal ability of steam generator 2, if the steam generator of 900W 2, this output just can not be greater than 0.05; Otherwise steam generator 2 cannot be processed much more so water and can be directly to the interior water spray of cooking cavity 11 simultaneously.
In addition, because user always has one to restrain oneself the limit to the cooking time of steam cooking apparatus 100, and, consider after three-way magnetic valve power-off, steam generator 2 works on the long time, can produce the problem that lack of water reports an error, so, the detection that maximum handling duration (being residual treatment time of water T) can not be greater than lack of water is carried and being called time (for example, for the steam generator 2 of 900W, detection time that reports an error can be 85 seconds～120 seconds), therefore select 1 minute with interior be proper, for example, 45s≤T≤60s.The concrete numerical value that is appreciated that residual treatment time of water T can be according to specific requirement specific design, to meet better user's demand.
When using the longest 1 minute during as residual water select time, according to the residual amount in water pipe, the length of for example water pipe is 300mm, volume is 2～3ml approximately, so now the output of this water pump 4 just should be not less than 6/400=0.015, round and be exactly 0.02 (taken advantage of weight coefficient α namely near this value), if output is too small, steam generator 2 is processed the residual water in end conduit not in finite time, as for this limited time, that the corresponding output of temperature section of being specified by cooking process limits, this limited timing definition is oversize or too short, capital causes the temperature in cooking cavity 11 within this period of time of processing residual water to there will be larger fluctuation.
In sum, for the steam generator 2 of 900W, the specific output β of water pump 4 can meet: 0.02≤β≤0.05, the output of water pump 4 should be the arbitrary value of selecting between 0.02～0.05.Simultaneously, consider viscosity, water pipe state and the water pump 4 propelling movement dynamics (i.e. unification represents with a weight coefficient α) of water, meet and in 1 minute, dispose residual water, the output of selected water pump 4 should be than the large ratio of minimum of a value 0.015, because different cooking temp sections has been set different water pumps 4 outputs, if this output should select within the scope of output in residual water treatment, carry out residual water treatment with regard to directly continuing to use this output, guarantee last minute temperature there will not be great fluctuation process; If (being to be all less than lower boundary conventionally) beyond the scope requiring in residual water treatment, directly selects lower boundary 0.02 to meet the demand of in 1 minute, residual water treatment being fallen.
Thus, according to the steam cooking apparatus 100 of the utility model embodiment, the impact of residual water will reduce greatly, for example steam microwave oven of steam cooking apparatus 100 is being long placed in the food-safety problem that is also not easy to occur peculiar smell or causes because of residual water, and, because the residual water in pipeline is discharged, steam cooking apparatus 100 does not have the impact of ponding at every turn in the time starting in pipeline, avoid steam generator 2 to be supplied water too early and produced approaching 100 degrees Celsius of Low Temperature Steams (condensation as quick as thought after ejection), the interior water of cavity 1 increased, increased user and clear up the problem of trouble.
