Background
In the related art, methods for detecting the state of the refrigerator (whether a load is placed or not) mainly include two types:
1. the refrigerator is provided with a scanning mechanism, and when a load is put into the refrigerator, the shelf life information of the load (namely food) is scanned and recorded, so that the state of the refrigerator is known, namely whether the load is put in or not is known, and the expiration reminding of the refrigerator is further controlled. Although the judging method can directly and accurately judge the state of the refrigerator, the method needs to add an additional code scanning mechanism on the refrigerator, needs manual operation of a user, and is high in implementation cost, complex in process and not intelligent enough.
2. Two types of sensors are arranged in the refrigerator, one type is a sensor for controlling a refrigerator chamber, the other type is a sensor for detecting the temperature of food in the chamber, and whether new food materials are put in is judged by judging the temperature change value and detecting the temperature absolute value of the food sensor.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
It should be noted that the refrigeration device in this embodiment may be, but is not limited to, a refrigerator or an ice chest, and in this embodiment, the refrigeration device is described as a refrigerator. The refrigerator is generally configured to have a plurality of compartments, wherein different compartments are correspondingly used for storing different food materials, such as a freezing compartment for storing meat food materials, a refrigerating compartment for storing fruit and vegetable food materials, and the like. When food materials are put into the refrigerator, in order to effectively control different food materials (such as rapid refrigeration and the like), the state of the refrigerator needs to be detected in advance, namely whether food materials are put into the refrigerator, but in the related art, methods for detecting whether food materials are put into the refrigerator are all realized by adding additional equipment on the refrigerator, so that the implementation cost is high, the detection process is complex, in addition, manual operation is needed in some cases, and the intelligence is poor. In view of this, a method, an apparatus, an electronic device and a storage medium for detecting a state of a refrigeration device in the embodiments of the present invention are provided.
It should be noted that, in the method for detecting the state of the refrigeration equipment in the embodiment of the present invention, the state of the refrigeration equipment is mainly determined by detecting the switching period of the damper/fan in the refrigeration equipment compartment and comparing the switching period with a preset period, which is described in detail below. For convenience of description, the refrigerating apparatus is hereinafter referred to as a refrigerator, and the food materials are collectively referred to as a load.
FIG. 1 is a flow chart of a method for detecting a state of a refrigeration appliance in an embodiment of the disclosure. As shown in fig. 1, the method for detecting the state of the refrigeration equipment according to the embodiment of the present invention includes the following steps:
s101: the working state of the damper/fan in the refrigeration equipment compartment is obtained.
It should be understood that the operation of the damper/fan in the refrigerator compartment includes both open and closed states, and that cooling of the compartment is achieved by opening and closing the damper/fan in the refrigerator compartment.
In some embodiments, in the process of using the refrigerator, after setting a fixed temperature T gear for the refrigerator compartment, the system generates upper and lower limits of temperature control correspondingly, at this time, the temperature sensor in the refrigerator compartment monitors the current temperature in the refrigerator compartment, and the working state of the damper/fan in the refrigerator compartment can be identified through the detected current temperature in the refrigerator compartment. Such as
As shown in fig. 2, during the operation of the refrigerator, the temperature sensor in the refrigerator compartment will monitor the current temperature in the refrigerator compartment, and when the current temperature in the refrigerator compartment monitored by the temperature sensor is lower than a first temperature T1 (i.e. a lower limit value of temperature control), the controller in the refrigerator controls the damper/fan to be closed, that is, the damper/fan can be determined to be in a closed state; when the current temperature in the refrigerator compartment monitored by the temperature sensor is higher than a second temperature value T2 (namely, the upper limit value of temperature control), the controller in the refrigerator controls the opening of the air door/fan, namely, the air door/fan can be determined to be in an open state at the moment; further, when the temperature inside the current refrigerator compartment is between the first temperature T1 and the second temperature T2, the damper/fan is continuously opened until the temperature inside the current refrigerator compartment is lower than the first temperature T1, and the damper/fan is closed.
S102: and determining the opening and closing period of the air door/fan according to the working state of the air door/fan.
In some embodiments, in calculating the open/close period of the damper/fan, the following calculations may be performed. Specifically, when the working state of the air door/fan is changed from closed to open, timing is started until the working state of the air door/fan is closed once and is opened again, and the timing is stopped, so that the switching period of the air door/fan is obtained; or, when the working state of the air door/fan is changed from open to closed, starting timing, and stopping timing until the working state of the air door/fan is opened once and closed again, so as to obtain the switching period of the air door/fan; that is, the time interval between two adjacent opening or closing of the damper/fan is taken as the switching period.
FIG. 3 is a graphical representation of the damper/fan switching event in one embodiment of the present disclosure. As shown in fig. 3, during normal stable operation of the refrigerator, after the damper/fan in the refrigerator compartment is closed, when the temperature in the refrigerator compartment is higher than the second temperature T2, the controller controls the damper/fan to open to cool the refrigerator compartment, at which time the controller records the time T1 when the damper/fan is opened, after the damper/fan is continuously operated for a period of time, the temperature in the refrigerator compartment will slowly decrease to be lower than the first temperature T1, at which time the controller controls the damper/fan to close, because of the factors such as the heat dissipation of the load in the refrigerator compartment itself, after the damper/fan is closed, the temperature in the refrigerator compartment will continuously increase, when the temperature rises to the second temperature T2, the controller controls the damper/fan to open again, at which time the controller records the time T2 when the damper/fan is opened, the switching period of the damper/fan, i.e., s 1-t 2-t1, can be obtained.
Another way to determine the damper/fan on/off period is that, during normal stable operation of the refrigerator, after the damper/fan in the refrigerator compartment is opened, when the temperature in the current refrigerator compartment is lower than the first temperature T1, the controller controls the damper/fan to close, at this time, the controller records the time T3 when the damper/fan is closed, after the damper/fan is closed, the temperature in the refrigerator compartment will continuously rise due to factors such as heat dissipation from the load in the refrigerator compartment itself, when the temperature rises to the second temperature T2, the controller controls the damper/fan to open, after the damper/fan continuously operates for a while, the temperature in the refrigerator compartment will slowly fall below the first temperature T1, at this time, the controller controls the damper/fan to close, at this time, the controller records the time T4 when the damper/fan is closed, the switching period of the damper/fan, i.e., s 2-t 4-t3, can be obtained.
It should be understood that there are many ways to determine the damper/fan on/off cycle based on the operating condition of the damper/fan in the refrigerator compartment, and therefore, the detailed description thereof is omitted.
S103: and if the switching period is less than the preset period, judging the state of the refrigeration equipment, wherein the state of the refrigerator comprises the load input/long-time door opening.
When the refrigerator is unloaded or the original load runs stably, the switching period of the damper/fan is relatively fixed, and the switching period time is relatively long because no additional heat load is increased, but when the condition of opening the door at the initial stage of adding the heat load or in a long time occurs, the heat load of the refrigerator compartment is increased instantly, so that the damper/fan is started and stopped frequently, and the switching period time is shortened.
In some embodiments, the preset period may be set by a user through a user interface on the refrigerator or an adjusting knob; in addition, in consideration of the using environment of the refrigerator, the influence of manual operation and the like, in order to obtain the preset period of opening of the air door/fan more accurately and further enable the refrigerator to be in the optimal operation state, the preset period can be obtained by average calculation through the controller according to the obtained switching period, and specifically, when the refrigerator is in the normal stable operation state, the controller obtains one or two or more switching periods of the air door/fan according to the method in the step. If the acquired switching period is one switching period, directly taking the period as a preset period; if two or more switching cycles are acquired, average calculation needs to be performed on the acquired switching cycles, so as to obtain a preset cycle. Taking three switching cycles as an example, where the first switching cycle is 3h, the second switching cycle is 3.2 hours, and the third switching cycle is 3.1h, the preset cycle is (3+3.2+3.1)/3 ═ 3.1 h. It should be understood that the normal stable operation state of the refrigerator means: and a load is not put into the refrigerator or the refrigerator door is not opened within the preset time, and at the moment, the opening and closing time of the air door/fan in the refrigerator is stabilized within the preset time range.
In some embodiments, the controller may misjudge the state of the refrigerator in consideration of the fact that the switching period is less than the preset period intermittently or once due to the influence of the operation factors of the refrigerator, and in order to avoid the misjudgment, the preset duration time that the switching period is less than the preset period is further set in the refrigerator controller. Before the state of the refrigerator is judged, the controller needs to acquire the duration of a switching period which is less than a preset period, if the duration is more than the preset duration, the subsequent steps are executed, otherwise, the controller returns to continuously acquire the working state of the air door/fan in the refrigerator chamber and judges again; such as: the preset duration time can be set to be n continuous periods, wherein the value range of n is 1-10 switching periods, and when the duration time of the switching period acquired by the controller, which is less than the preset period, is greater than n, the state of the refrigerator is judged.
In some embodiments, in order to further determine what state the refrigerator is in, after determining the state of the refrigerator, considering that the state of the refrigerator includes two states of load placing and long-time door opening, further, the state of the refrigerator door is detected, if the refrigerator door is in an open state, it is determined that the refrigerator is in a long-time door opening state, and if the refrigerator door is in a closed state, it is determined that the refrigerator is in a load placing state. When detecting the refrigerator door state, can detect refrigerator gate switch state or detect whether the light is opened and judge in the refrigerator, if when detecting the light and open, then judge that the refrigerator door is in the open mode. There are many ways to detect the state of the refrigerator door, and those skilled in the art can select the state according to actual situations, and thus detailed description is omitted here.
In some embodiments, if the refrigerator door is in a long-time opening state, the refrigerator can be caused to increase in power consumption or cause the situation such as load corruption in a refrigerator chamber, in order to avoid the situation, an alarm device can be further arranged on the refrigerator, when the refrigerator door is detected to be in the long-time opening state, the controller sends an alarm instruction to the alarm device, the alarm device gives an alarm to remind a user to close the refrigerator door, wherein the alarm device can be a buzzer, a loudspeaker and the like.
In some embodiments, after determining that the refrigerator is in the load-in state, the controller adjusts the first preset temperature (i.e., the fixed temperature T in step S101) in the refrigerator compartment to the second preset temperature, wherein the first preset temperature is higher than the second preset temperature, and controls the damper/fan to open, in such a way, the temperature in the refrigerator compartment can be rapidly reduced to meet the user' S requirement, for example, when the load is a beverage, the user can obtain a low-temperature beverage in a short time.
Further, when the temperature sensor in the refrigerator compartment detects that the current temperature in the refrigerator compartment reaches a second preset temperature, the controller adjusts the second preset temperature in the refrigerator compartment to the first preset temperature, namely, the refrigerator is restored to a normal and stable operation state at the moment.
FIG. 4 is a control flow diagram of a method for detecting the status of a refrigeration unit in an embodiment of the present disclosure. As shown in fig. 4, when the method for detecting the state of the refrigeration equipment in the embodiment of the present invention is implemented, for convenience of description, the following steps are used to describe:
the first step is as follows: acquiring the working state of an air door/fan in a refrigeration equipment compartment;
the second step is that: determining the opening and closing period of the air door/fan according to the working state of the air door/fan;

and a sixth step: detecting whether a refrigeration equipment door is opened or not, and determining that the refrigeration equipment is opened for a long time when the refrigeration equipment door is opened; otherwise, the state of the refrigeration equipment is determined to be that a load is put in.
