With reference to description below and accompanying drawing, these and other aspects of embodiments of the invention will be known.Describe at these and in accompanying drawing, specifically disclose some particular implementation in embodiments of the invention, representing some modes of the principle implementing embodiments of the invention, but should be appreciated that the scope of embodiments of the invention is not limited.On the contrary, embodiments of the invention comprise fall into attached claims spirit and intension within the scope of all changes, amendment and equivalent.
Below in conjunction with accompanying drawing, control method, system and the refrigerator according to the refrigerator of the embodiment of the present invention is described.
Refrigerator comprises a room, wind blade and multiple temperature sensor, and wherein, a room has air outlet and return air inlet, and wind blade is arranged on air outlet, and multiple temperature sensor is positioned at multiple regions of a room.Wherein, wind blade can think the grid at air outlet place, or is similar to the wind guide vane of air-conditioning.
Fig. 1 is the flow chart of the control method of refrigerator according to an embodiment of the invention.As shown in Figure 1, the control method of refrigerator according to an embodiment of the invention, comprises the following steps:
Step S101: detect whether open refrigerator doors.
Step S102: if then obtain the fiducial temperature in multiple regions that multiple temperature sensor detects when opening refrigerator doors, and in delay scheduled time, again obtain the transient temperature in multiple regions that multiple temperature sensor detects.
Wherein, the scheduled time is [8 minutes, 12 minutes].In one embodiment of the invention, for 10 minutes.That is, if detect that user opens refrigerator doors, then when opening, the temperature in multiple regions indoor between the multiple temperature sensors obtained now detect, and using this temperature as fiducial temperature.Then, after 10 minutes, again obtain current multiple temperature sensors detect between the temperature in indoor multiple regions, as transient temperature.
Step S103: judge whether to exist in multiple region the first area that difference variation is greater than the default temperature difference according to fiducial temperature and up time temperature.In one embodiment of the invention, predetermined temperature difference is [2 DEG C, 4 DEG C].For 3 DEG C.
Such as: user has put hotter food etc. in certain region, within a period of time originally (such as a few minutes or tens minutes), the meeting that this regional temperature raises is relatively very fast, usually also can be higher than the temperature in other region.Like this, if this region up time temperature is now higher than fiducial temperature, and higher 3 DEG C than the fiducial temperature in this region, then think that this region is the first area being greater than the default temperature difference (as 3 DEG C) in difference variation.
Step S104: if existed, then enter fast cold pattern, controls wind blade action with towards first area wind-guiding.Enter fast cold pattern, the refrigeration system of refrigerator is freezed, and air outlet sends cold wind to a room, and controls wind blade action with towards first area wind-guiding.Like this, the cold wind of air outlet is just blown in first area, the temperature of first area is declined rapidly, thus reduces the temperature contrast of whole room, promotes intelligent requirements and the performance of refrigerator.
Further, if judge do not have difference variation to be greater than the region of the default temperature difference in multiple region, then according to the design temperature of user, refrigerator is controlled.Namely the compartment temperature that refrigerator sets according to user carries out normal startup-shutdown control to refrigeration system.
As shown in Figure 2, in a concrete example of the present invention, multiple region comprises top left region, right regions, lower left region and lower right area, multiple temperature sensor comprises 4 temperature sensors being positioned at top left region, right regions, lower left region and lower right area, is namely positioned at the sensor 4 of the sensor 1 of the top left region of a room, the sensor 3 of right regions, the sensor 2 of lower left region and lower right area.Wherein, sensor 1 and sensor 2 are such as arranged on the inner bag of left side, and sensor 3 and sensor 4 are such as arranged on the inner bag of right side.
Again shown in composition graphs 2, air outlet and air inlet (i.e. return air inlet) are arranged on backboard.Air outlet comprises three air outlets, is respectively air outlet 1, air outlet 2 and air outlet 3 from top to bottom.Air outlet 1, air outlet 2 and air outlet 3 are equipped with wind blade (variable grid as shown in Figure 2).Wind blade comprises horizontal wind blade and longitudinal wind blade.The wind direction of such wind-guiding can upwards wind-guiding, downwards wind-guiding, left wind-guiding and to the right wind-guiding.Namely variable grid is made up of horizontal and vertical wind blade, ensures that air port can turn to surrounding when turning to.
Based on refrigerator as described in Figure 2, as shown in Figure 3, control mode comprises the specific implementation of the method for the embodiment of the present invention:
1, have in door opening action process at refrigerating chamber, the temperature of flashy 4 sensors of record door opening process is as fiducial temperature;
2, record the transient temperature of 4 sensors in the 10min after enabling constantly, and compared with fiducial temperature, as 4 sensors temperature difference compared with fiducial temperature is all less than 3 DEG C, then continue to control according to original start-stop point temperature difference.Otherwise, be greater than 3 DEG C (get on the occasion of) if any arbitrary sensor temperature temperature difference compared with fiducial temperature, then enter fast cold control model.
After entering fast cold control model, as follows to the control of wind blade:
1) reset air outlet grid positions: swing up and down grid to horizontal level, the grid that swings is to upright position;
2) rotation speed of fan modulation maximum (top) speed;
3) sensing station at temperature difference maximum place is chosen;
4) grid action is as follows:
Sensor 1 (representing that the difference of the transient temperature that sensor 1 detects and fiducial temperature is greater than 3 DEG C):
1, air outlet about 1 does not deflect, and deflects 90 ° left
2, air outlet 2 upward deflects 90 °, deflects 90 ° left
3, air outlet 3 upward deflects 90 °, deflects 90 ° left
Sensor 3:
1, air outlet 1 deflects 90 ° to the right, does not deflect up and down
2, air outlet about 2 does not deflect, and deflects 90 ° to the right
3, air outlet 3 upward deflects 90 °, deflects 90 ° to the right
Sensor 2:
1, air outlet 1 deflects 90 ° left, deflects down 90 °
2, air outlet 2 deflects down 90 °, deflects 90 ° to the right
3, air outlet about 3 does not deflect, and deflects 90 ° left
Sensor 4:
1, air outlet 1 deflects down 90 °, deflects 90 ° to the right
2, air outlet 2 deflects down 90 °, deflects 90 ° to the right
3, air outlet about 3 does not deflect, and deflects 90 ° to the right
By monitoring the temperature difference of 4 sensors and fiducial temperature constantly, if the temperature difference of the temperature of 4 sensors and fiducial temperature is all less than 3 DEG C, then exit fast cold control.If the temperature of arbitrary sensor and the temperature difference of fiducial temperature are greater than 3 DEG C, then continue fast cold pattern.
