The invention will be further described by the description of embodiments with reference to the accompanying drawings.
The embodiment provides a control method of a refrigerator, as shown in fig. 1, the method includes:
and S10, detecting the odor sensitivity level of the refrigerator configuration when the first odor intensity value of the odor in the storage chamber of the refrigerator is detected.
Specifically, the first odor intensity value is detected by an odor sensor arranged in a storage chamber of the refrigerator, wherein the odor sensor is arranged in the storage chamber of the refrigerator and used for detecting the odor intensity of gas in the storage chamber of the refrigerator. The odor sensor adopts odor in a refrigerator storage chamber and outputs an odor intensity value of the odor. The odor intensity value is a number, and the number represents the gas environment in the refrigerator storage chamber, wherein different numbers or number intervals correspond to different gas environments in the refrigerator storage chamber.
Further, the refrigerator is preconfigured with a smell mode, the smell mode comprises a sensitivity mode and an automatic registration mode, the sensitivity mode is used for determining display information according to smell intensity, and the automatic registration mode is used for automatically calibrating a detection reference of the smell sensor. In this embodiment, the sensitivity pattern includes at least two odor sensitivity levels, a high level and a normal level, respectively. The automatic registration mode is to acquire an odor intensity value in a refrigerator storage chamber according to a preset rule, and adjust a detection reference of an odor sensor according to the odor intensity value.
Further, in an embodiment, a plurality of smell sensors may be disposed in the refrigerator storage chamber, the plurality of smell sensors respectively detect smell intensity values in the refrigerator storage chamber, and feed back the detected smell intensity values to the refrigerator, and calculate a first smell intensity value of the refrigerator storage chamber according to the received plurality of smell intensity values. The first smell intensity value may be an average value of a plurality of collected smell intensity values, may be obtained by weighting a plurality of collected smell intensity values, or may be a maximum value or a minimum value of a plurality of collected smell intensity values.
Further, in an embodiment, the first odor intensity value is detected when the refrigerator storage compartment is in a door-closed state. When detecting a first odor intensity value of odor in a storage room of a refrigerator, detecting an odor sensitivity level of an odor mode configured by the refrigerator specifically includes:
detecting the state of a door body of a storage chamber of the refrigerator;
when the door body is in a door closing state, detecting a first odor intensity value of odor in a storage chamber of the refrigerator in real time through an odor sensor;
and detecting the odor sensitivity level of the odor mode configured by the refrigerator when the first odor intensity value of the odor in the storage chamber of the refrigerator is detected.
Specifically, an inductor may be disposed on a door body of the refrigerator storage chamber, and a state of the door body of the refrigerator storage chamber may be detected through the inductor, where the state includes a door opening state and a door closing state. That is, the state of the door body of the storage chamber of the refrigerator is detected by the sensor, and when the door body is detected to be in the door closing state, a first odor intensity value of the odor in the storage chamber of the refrigerator is detected by the odor sensor in real time.
And S20, searching an odor intensity interval in which the odor intensity is located in a preset odor intensity interval database when the odor sensitivity level is high.
Specifically, the odor intensity interval database is preset and is used for storing each odor intensity interval, and each odor intensity interval corresponds to different odor grades. When the odor sensitivity level is high, the corresponding odor intensity interval is directly searched in a preset odor intensity interval database so as to determine the display information corresponding to the first odor intensity value. For example, 3 odor intensity intervals, which are respectively 0-49,50-69 and 70-99, are pre-stored in the preset odor intensity interval database. The higher the odor intensity value corresponding to the odor intensity interval, the more fresh the air between the refrigerator storage. For example, the 0-49 correspondence grade is poor, the 50-69 correspondence grade is medium, and the 70-99 correspondence grade is good.
S30, determining display information corresponding to the odor in the storage room according to the odor intensity interval, and displaying the display information on a display interface.
In particular, the display information includes odor level and display color, and different levels may be displayed in different colors. For example, severe corresponds to red, medium corresponds to yellow, good corresponds to green. After the display information is acquired, the display information can be displayed on a display interface configured with the refrigerator itself. In addition, the refrigerator can send the display information to an external terminal connected with the refrigerator, for example, the display information is sent to an APP for managing the refrigerator and is displayed on a terminal device loaded with the APP through the APP, so that a user can timely acquire the state of food in a storage chamber of the refrigerator. In addition, after the display information is displayed on the display interface, different food states can be displayed on the display module according to the corresponding relation between the gas environment and the food health condition in the refrigerator. Of course, the corresponding processing mode can be determined according to the display information, for example, the fresh-keeping device is opened in a medium state, the deodorizing device is opened in a bad state, and the like. Namely, the refrigerator can be provided with a fresh-keeping device and a deodorizing device, and the device which needs to be opened is determined according to the display information so as to improve the fresh-keeping effect of the refrigerator.
Further, in one embodiment, the method further comprises:
when the odor sensitivity level is a common level, calculating a first difference value between each acquired critical value and the first odor intensity value, and judging whether the first difference value meets a preset condition;
if the first difference value meets a preset condition, acquiring the change trend of the smell intensity;
and determining display information corresponding to the odor in the storage room according to the change trend, and displaying the display information on a display interface.
Specifically, the threshold value is a threshold value of each odor interval. Meanwhile, the odor intensity value cannot be higher than the upper limit value of the maximum odor intensity interval and cannot be lower than the lower limit value of the minimum odor intensity interval, so that the obtained critical value does not comprise the upper limit value of the maximum odor intensity interval and the lower limit value of the minimum odor intensity interval. For example, the odor intensity ranges are 0-49,50-69,70-99, respectively, and the obtained threshold values are 49,50,69 and 70, respectively.
Further, the absolute value of the difference between the first smell intensity value and the critical value of the smell intensity region is smaller than a preset threshold, that is, the determining whether the first difference value meets a preset condition is determining whether the absolute value of the first difference value is smaller than a preset threshold. In addition, when the plurality of critical values are obtained, a plurality of first difference values may be obtained, and then determining whether the first difference values meet the preset condition is determining whether a first difference value with an absolute value smaller than a preset threshold value exists in the plurality of first difference values, and determining that the first difference value meets the preset condition.
In addition, when the first difference value is determined to meet the preset condition, the change trend of the first smell intensity value relative to the third smell intensity value at the previous moment is acquired, and the change trend is recorded as the change trend of the smell intensity. When the first smell intensity value is equal to the third smell intensity value at the previous moment, the change trend corresponding to the third smell intensity value at the previous moment is taken as the change trend corresponding to the first smell intensity value. The trend of change includes an increasing trend and a decreasing trend, for example, the first smell intensity value is 73, and if the third smell intensity value at the previous moment is 72, the trend of change corresponding to the first smell intensity value is an increasing trend; if the third odor intensity value at the previous moment is 71, the change trend corresponding to the first odor intensity value is a decreasing trend.
Further, in an embodiment, the determining, according to the change trend, display information corresponding to the smell in the storage room, and displaying the display information on a display interface specifically includes:
acquiring the sign of the first difference value and the ascending and descending property of the variation trend;
when the sign is positive and the lifting performance is raised, searching a smell intensity interval in which the smell intensity is located in a preset smell intensity interval database;
and acquiring display information corresponding to the previous intensity interval of the smell intensity interval, and displaying the display information on a display interface.
Specifically, the preset condition is that the absolute value of the difference is greater than a preset threshold, so that when the first difference meets the preset condition, the first odor intensity can be greater than a critical value corresponding to the first difference meeting the preset condition, namely the first critical value, or can be smaller than the first critical value corresponding to the first difference, and at the moment, a sign of the first difference can be obtained, wherein the sign comprises a positive sign and a negative sign. The positive sign indicates that the first odor intensity is greater than a first threshold value, and the sign indicates that the first odor intensity is less than the first threshold value. In practical application, as the difference between the adjacent critical values of the two adjacent odor intensity intervals is small, a numerical value with a larger numerical value is selected from the adjacent critical values of the two adjacent odor intensity intervals as the critical value, and the numerical value with a smaller numerical value is removed. For example, the obtained critical values are 49,50,69 and 70, respectively, and the filtered critical values are 50 and 70, respectively. This also simplifies the process of displaying information and improves the display rate of the displayed information. In this embodiment, the preset threshold may be preset, and the sensitivity of the scent display may be adjusted by adjusting the preset threshold. That is, a plurality of thresholds can be stored in the refrigerator in advance for users to select, so as to meet the requirements of different users.
Further, when the sign is positive and the ascending and descending performance is raised, it means that the first odor intensity value is greater than the first critical value, and the trend of change of the first odor intensity value is raised, at this time, a previous odor intensity interval of the odor intensity interval in which the first odor intensity value is located is obtained, where the previous and subsequent odor intensity intervals are arranged from small to large according to the odor intensity values included in the odor intensity interval, that is, the odor intensity interval with a small value is arranged in front, and the odor intensity interval with a large value is arranged in back. For example, 1-49 may be arranged in front of 50-69 and 70-99 may be arranged behind 50-69. Further, an example is given here in which the sign is positive and the liftability is raised. For example, the first odor intensity values 73,73 and 70 have a difference value of 3, the sign is positive, the second odor intensity value at the previous time of the first odor intensity value is 72, and the trend of change is rising; in addition, if the odor intensity interval where 73 is located is 70-99, the odor intensity interval of 50-69 is obtained as the odor intensity interval corresponding to 73, and the display information corresponding to 50-69 is taken as the display information corresponding to the first odor intensity value 73.
In addition, in this embodiment, the determining, according to the change trend, display information corresponding to smell in the storage room, and displaying the display information on a display interface further includes:
when the sign is negative and the lifting performance is reduced, searching an odor intensity interval in which the odor intensity is located in a preset odor intensity interval database;
and acquiring display information corresponding to the odor intensity interval behind the odor intensity interval, and displaying the display information on a display interface.
Specifically, the later odor intensity interval is arranged from small to large according to odor intensity values included in the odor intensity interval, and the odor intensity interval is arranged after the odor intensity interval is acquired. For example, the first odor intensity value corresponds to an odor intensity interval of 50-69, and then the subsequent odor intensity interval is 70-99. In addition, an example is given here in which the sign is negative and the ascending and descending property is reduced for further description. For example, the first odor intensity value is 68,68 and 70 have a difference value of-2, the sign is negative, the second odor intensity value at the previous time of the first odor intensity value is 72, and the trend of change is declining; in addition, if the odor intensity interval where 68 is located is 50-56, the odor intensity interval of 70-99 is obtained as the odor intensity interval corresponding to 68, and the display information corresponding to 70-99 is taken as the display information corresponding to the first odor intensity value 68.
Further, in one embodiment, the automatic registration mode and the sensitivity mode may be turned on simultaneously, that is, when detecting the odor intensity value in the storage chamber of the refrigerator according to the sensitivity mode, the refrigerator may automatically adjust the detection reference of the odor sensor so as to avoid the influence of gas exchange caused by the door opening and the mixing of the odor in the refrigerator and the taste of the newly placed food materials on the odor sensor. Correspondingly, the method further comprises the steps of:
detecting a closing event of a door body of the storage chamber when the automatic registration mode is monitored to be opened;
after the door body is closed for a preset time, detecting a second odor intensity value between the storage objects, and comparing the second odor intensity value with a standard reference value;
when the second odor intensity value is larger than the standard reference value, early warning prompt is carried out;
and when the second odor intensity value is smaller than a standard reference value, calibrating the standard reference state of the odor sensor by adopting the second odor intensity value to correspond to the odor state.
In particular, the door closing event may be detected by a sensor for sensing a door of a refrigerator. When the closing event of the door body is detected, monitoring the closing time of the door body and detecting a second odor intensity value between the storage objects when the closing time reaches a preset time. And when the second smell intensity value is detected, comparing the second smell intensity value with a factory set standard reference value to judge whether the smell sensor needs to be calibrated. Wherein the standard reference value is an odor intensity value for representing fresh air in a storage room of the refrigerator. In this embodiment, the standard reference value is the maximum value of the odor intensity value, e.g., 99. In addition, calibrating the standard reference state of the odor sensor with the second odor intensity value corresponds to using the odor state collected by the odor sensor corresponding to the second odor intensity value as the standard state, and determining the odor intensity value based on the odor state collected by the odor sensor corresponding to the second odor intensity value in the later collected state. That is, after calibration, the second odor intensity value is mapped to a standard reference value. In addition, after the refrigerator is opened to before the refrigerator is closed, if the gas sensor detects that the first odor intensity value is increased, the display information is determined according to the increased first odor intensity value, and if the first odor intensity value is reduced, the display information is kept inconvenient until the refrigerator is closed for a preset time, for example, 5 minutes.
Further, in one embodiment, the method further comprises:
when the automatic registration mode is closed, receiving a reference value of the smell intensity input by a user;
if the reference value is received, setting the reference value as a standard reference value;
if the reference value is not received, the default scent intensity value is set to a standard reference value.
Specifically, when the automatic registration mode is closed, manual calibration and factory calibration restoration can be performed by a user, wherein the manual calibration is to judge the current state as an optimal state and replace the original reference value, namely the current state is calibrated to be 99; and restoring the factory setting to restore the fresh state reference value to the factory setting value.
