Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
With reference to Fig. 1, control method one embodiment of micro-wave oven of the present invention is proposed.The control method of this micro-wave oven, comprises the following steps:
Relative humidity in step S10, detection micro-wave oven and temperature;
Because micro-wave oven is when heating food, steam can be produced.Therefore, relative humidity sensor is set in micro-wave oven, for periodically detecting relative humidity in micro-wave oven and temperature.
Step S20, according to the relative humidity in described micro-wave oven, judge whether micro-wave oven is in zero load; Proceed to step S50; Otherwise proceed to step S30;
Micro-wave oven no-load running refers to does not place anything in micro-wave oven and micro-wave oven is in running order, is so easy to damage micro-wave oven.And because micro-wave oven is when heating food, can steam be overflowed, then the humidity in micro-wave oven also can increase along with the heating of food gradually.And micro-wave oven is when zero load, owing to there is no food in micro-wave oven, so the humidity in micro-wave oven reduces gradually along with heating.Therefore, in the running of micro-wave oven, by periodically detecting the relative humidity in micro-wave oven, according to the change of the relative humidity in micro-wave oven, can judge whether micro-wave oven is in zero load, and then carry out corresponding micro-wave oven control according to judged result.
Relative humidity in step S30, continuation detection micro-wave oven and temperature;
When judging that micro-wave oven is in not unloaded, namely representing in micro-wave oven and being placed with food, then control micro-wave oven and work on, and continue to detect the relative humidity in micro-wave oven and temperature.
Step S40, to compare with preset relative humidity and temperature according to the relative humidity of described micro-wave oven and temperature, judge whether the food in micro-wave oven completes heating; Proceed to step S50; Otherwise proceed to step S30;
Step S50, control micro-wave oven quit work.
Above-mentioned preset relative humidity is the relative humidity of food when completing heating in micro-wave oven, and in like manner, preset temperature is also the temperature in micro-wave oven when food completes heating.According to the relative humidity of micro-wave oven and temperature and preset relative humidity and temperature, then can judge whether the food in micro-wave oven completes heating, and control micro-wave oven according to judged result and operate accordingly.
The present invention passes through periodically to detect the relative humidity in micro-wave oven and temperature, and according to detected relative humidity, when judging that micro-wave oven is in zero load, controls micro-wave oven and quit work; When micro-wave oven is not in zero load, compare with preset relative humidity and temperature according to detected relative humidity and temperature, when the food judging in micro-wave oven completes heating, control micro-wave oven and quit work.The present invention, by simple control mode, realizes the control of micro-wave oven, and can judge that whether micro-wave oven is unloaded and whether complete heating accurately and timely by the detection of relative humidity and temperature.
Further, with reference to Fig. 2, also comprise before above-mentioned steps S10:
Step S00, the classification of heat food is set.Because food in micro-wave oven can be solid or liquid etc., and during the heating of this two group food, relative humidity when having judged heating in micro-wave oven and temperature also can be different.Therefore, user is after placing micro-wave oven by food, and will select the mode of operation of micro-wave oven, then micro-wave oven is according to the setting of this mode of operation, can judge the classification of this heat food, and arrange it, has judged heating more exactly so that follow-up.
Further, with reference to Fig. 3, above-mentioned steps S20 comprises:
Step S21, judge current detected relative humidity RHn whether be greater than before once detected relative humidity RHn-1, and whether front once detected relative humidity RHn-1 is greater than the front relative humidity RHn-2 detected for twice; Proceed to step S23; Otherwise proceed to step S22; Wherein n be more than or equal to 2 positive integer;
Step S22, judge that micro-wave oven is in zero load;
Step S23, judge that micro-wave oven is not in zero load.
Because micro-wave oven is when heating food, can overflow steam, then the humidity in micro-wave oven also can increase along with the heating of food gradually.And micro-wave oven is when zero load, owing to there is no food in micro-wave oven, so the humidity in micro-wave oven reduces gradually along with heating.Therefore, in the running of micro-wave oven, by periodically detecting the relative humidity in micro-wave oven, judging the change of the relative humidity in micro-wave oven, if the relative humidity in micro-wave oven is in the trend reduced gradually, then representing that it is in Light Condition; If the relative humidity in micro-wave oven is in the trend risen continuously, then represent that it is in non-Light Condition.
Suppose n=2, then the relative humidity detected for the first time is RH0 (relative humidity detected when namely micro-wave oven starts), and the relative humidity that second time detects is RH1, and the relative humidity that third time is detected is RH2.If RH2>RH1 and RH1>RH0, then represent that micro-wave oven is in unloaded; Otherwise it is not unloaded to represent that micro-wave oven is in.
Further, with reference to Fig. 4, above-mentioned steps S40 comprises the following steps:
Step S41, classification according to heat food, obtain relative humidity preset accordingly and temperature;
Whether the relative humidity that step S42, judgement detect is more than or equal to preset relative humidity, and whether the temperature detected is more than or equal to preset temperature; Proceed to step S43; Otherwise proceed to step S44;
Step S43, the food judged in micro-wave oven complete heating;
Step S44, the food judged in micro-wave oven do not complete heating.
When detected relative humidity is more than or equal to preset relative humidity, and when the temperature detected is more than or equal to preset temperature, then represent that food completes heating, then micro-wave oven can power cut-off.Because the food that heats in micro-wave oven can be liquid, also can be solid, and when this two group food heats, relative humidity when completing heating in micro-wave oven and temperature also can be different.So first according to the classification of food in micro-wave oven, corresponding preset relative humidity and temperature will be obtained, and then judge whether the food in micro-wave oven completes heating, make the control of micro-wave oven more accurate thus.In the present embodiment, the relative humidity of food when completing heating in micro-wave oven and temperature are 80% and 30 DEG C, and the relative humidity of liquid food when completing heating in micro-wave oven and temperature are 92% and 30 DEG C.Certainly, relative humidity when completing heating in micro-wave oven and temperature can be arranged according to other situations, also can be set to other values, in this no limit.
Understandable, in above-mentioned steps S42, judge that the relative humidity detected is more than or equal to preset relative humidity, and the temperature detected is when being more than or equal to preset temperature, represent that food completes heating, can control micro-wave oven to quit work, but also can control micro-wave oven works on after a period of time again, stops the work of micro-wave oven.This time can be arranged as the case may be and specifically, in this no limit.
With reference to Fig. 5, control device one embodiment of a kind of micro-wave oven of the present invention is proposed.The control device of this micro-wave oven comprises:
Relative humidity sensor 10, for periodically detecting relative humidity in micro-wave oven and temperature, until micro-wave oven quits work;
Controller 20, for according to the relative humidity in micro-wave oven, judges whether micro-wave oven is in zero load, is, controls micro-wave oven and quit work; Otherwise according to relative humidity and temperature, preset relative humidity and the temperature of described micro-wave oven, judge whether the food in micro-wave oven completes heating; If complete heating, then control micro-wave oven and quit work; If do not complete heating, then control micro-wave oven and work on.
Because micro-wave oven is when heating food, steam can be produced.Therefore, relative humidity sensor 10 is set in micro-wave oven, for periodically detecting relative humidity in micro-wave oven and temperature.This relative sensors can be arranged on side or the top of microwave oven cavity.Initial RH when this micro-wave oven starts can be micro-wave oven default setting, can certainly be: when micro-wave oven starts, pass through relative humidity sensor, detect the relative humidity in micro-wave oven, as initial RH, and it is stored, for follow-up.Because under being in different environment, so the initial RH dynamically arranged when micro-wave oven starts can be more accurate to the operation of follow-up micro-wave oven.Micro-wave oven no-load running refers to does not place anything in micro-wave oven and micro-wave oven is in running order, is so easy to damage micro-wave oven.Therefore, controller 20 according to the relative humidity in micro-wave oven, then can judge whether micro-wave oven is in zero load, and carry out corresponding micro-wave oven control according to judged result.And, according to the relative humidity in detected micro-wave oven and temperature and preset relative humidity and temperature, also judge whether the food in micro-wave oven completes heating, and control micro-wave oven when having judged heating and quit work.Above-mentioned preset relative humidity is the relative humidity of food when completing heating in micro-wave oven, and in like manner, preset temperature is also the temperature in micro-wave oven when food completes heating.
It by periodically detecting the relative humidity in micro-wave oven, and compares with initial RH when micro-wave oven starts by the present invention, and when judging that micro-wave oven is in zero load, control micro-wave oven quits work.The present invention, by simple control mode, realizes the control of micro-wave oven, and can judge that whether micro-wave oven is unloaded and whether complete heating accurately and timely by the detection of relative humidity.
Further, above-mentioned controller 20 specifically for:
Judge current detected relative humidity RHn whether be greater than before once detected relative humidity RHn-1, and whether front once detected relative humidity RHn-1 is greater than the front relative humidity RHn-2 detected for twice; Be judge that micro-wave oven is not in zero load, otherwise judge that micro-wave oven is in zero load.
Because micro-wave oven is when heating food, can overflow steam, then the humidity in micro-wave oven also can increase along with the heating of food gradually.And micro-wave oven is when zero load, owing to there is no food in micro-wave oven, so the humidity in micro-wave oven reduces gradually along with heating.Therefore, in the running of micro-wave oven, the relative humidity in micro-wave oven is periodically detected by relative humidity sensor 10, controller 20 judges the change of the relative humidity in micro-wave oven, if the relative humidity in micro-wave oven is in the trend reduced gradually, and continue one first preset time t1, then represent that it is in Light Condition; If the relative humidity in micro-wave oven is in the trend risen continuously, then represent that it is in non-Light Condition.
Further, above-mentioned controller 20, also for the classification of heat food set when starting according to micro-wave oven, obtains relative humidity preset accordingly and temperature; If the relative humidity detected is more than or equal to preset relative humidity, and the temperature detected is more than or equal to preset temperature, then judge that the food in micro-wave oven completes heating; Otherwise the food in judgement micro-wave oven does not complete heating.
When detected relative humidity is more than or equal to preset relative humidity, and when the temperature detected is more than or equal to preset temperature, then represent that food completes heating, then micro-wave oven can power cut-off.Because the food that heats in micro-wave oven can be liquid, also can be solid, and when this two group food heats, relative humidity when completing heating in micro-wave oven and temperature also can be different.So controller 20 first according to the classification of heat food in micro-wave oven, will obtain corresponding preset relative humidity and temperature, and then judge whether the food in micro-wave oven completes heating, make the control of micro-wave oven more accurate thus.In the present embodiment, the relative humidity of food when completing heating in micro-wave oven and temperature are 80% and 30 DEG C, and the relative humidity of liquid food when completing heating in micro-wave oven and temperature are 92% and 30 DEG C.Certainly, relative humidity when completing heating in micro-wave oven and temperature can be arranged according to other situations, also can be set to other values, in this no limit.
Understandable, above-mentioned controller 20 judges that the relative humidity detected is more than or equal to preset relative humidity, and the temperature detected is when being more than or equal to preset temperature, then represent that food completes heating, therefore can control micro-wave oven to quit work, but also can control micro-wave oven works on after a period of time again, stops the work of micro-wave oven.This time can be arranged as the case may be and specifically, in this no limit.
Present invention also offers a kind of micro-wave oven, it comprises the control device be arranged in micro-wave oven, and the structure and working principle of this control device can refer to noted earlier and reference Fig. 5, just repeats no more at this.
The foregoing is only the preferred embodiments of the present invention; not thereby its scope of the claims is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; directly or indirectly be used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present invention.
