Description
Technical Field
The application relates to the technical field of refrigerators, in particular to a temperature control method, a temperature control device, a temperature control system and a refrigerator.
Background
The refrigerator is a refrigerating device capable of keeping constant low temperature, and food or other articles are kept in a low temperature state, so that the freshness of the food or other articles is realized, and the spoilage is delayed. The storage compartments of the refrigerator may include a refrigerating compartment, a temperature varying compartment, and a freezing compartment according to the difference in storage temperature. The refrigerating chamber is the area inside the refrigerator with temperature maintained at 0-10 deg.c and is used mainly in storing perishable food, such as vegetable, fruit, milk, yoghurt, etc. The temperature-changing chamber is a region in which the temperature in the refrigerator is kept between-5 ℃ and 0 ℃ and is mainly used for storing foods such as meat, fish and the like. The freezing chamber refers to the area of the refrigerator, which keeps the temperature below-18 ℃, and is mainly used for storing frozen foods, such as ice cream, quick frozen foods and the like.
In the prior art, a temperature sensor is usually provided in the storage chamber to detect the temperature in the storage chamber. When the temperature needs to be adjusted, whether the temperature is adjusted to the set temperature is judged through the temperature sensed by the temperature sensor. However, when the temperature is adjusted, cold air enters the refrigerating chamber from the air duct, and the air is unevenly distributed in the refrigerating chamber, so that the accuracy of the temperature measured by the temperature sensor in the refrigerating chamber is not high. If the temperature of the gas accumulation area is detected, the temperature is lower, and the temperature sensor easily misjudges that the food reaches the preset temperature, so that the refrigeration device stops refrigeration, and the cooling time is insufficient. If the temperature of the gas sparse zone is detected, the temperature is higher, and the temperature sensor is easy to misunderstand that the food does not reach the preset temperature, so that the refrigerating device continues to refrigerate, and supercooling phenomenon occurs in other zones. If the temperature sensors are arranged on different wall surfaces, a large amount of space is occupied, and the complexity of temperature calculation is increased.
Therefore, the reliability of the refrigerator temperature control method is to be further improved.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
In the description of the present application, it should be understood that the words "first" and "second" are used for descriptive purposes only and are not to be interpreted as indicating or implying a relative importance or number of features in which such is indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more features.

In other instances, well-known structures and processes have not been described in detail so as not to obscure the description of the application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles disclosed herein.
It should be noted that, the storage room in the technical scheme of the application can be a refrigerating room, a temperature changing room or a freezing room.
Referring to fig. 1, the present application provides a temperature control method. The temperature control method is applied to a refrigerator, and the refrigerator is provided with a storage chamber, wherein a light emitter and a light receiver are arranged in the storage chamber. Specifically, the temperature control method can be applied to a temperature controller of the refrigerator or a third party terminal device in signal connection with the temperature controller of the refrigerator.
It should be noted that, the light emitter and the light receiver work when the refrigerator door is closed, so as to avoid the influence of the light received by the light receiver from outside the refrigerator on the reliability of temperature control when the refrigerator door is opened.
In some embodiments, the temperature control method may include the following steps.
S11, acquiring the current light propagation time in the storage chamber of the refrigerator, wherein the current light propagation time is the duration from the light emitter to the light receiver.
Further, the light propagation time refers to the time difference between the same light emitted from the light emitter and the light receiver in the storage room of the refrigerator. For example, at t 1 The light emitter emits light at the moment of time, t 2 The light receiver receives the light at the moment, and the current light propagation time is t 2 -t 1 . The light propagates faster in the storage chamber, which increases the efficiency of temperature control.
It will be appreciated that the propagation time of light is related to the temperature of its propagation medium. In the storage chamber of the refrigerator, the lower the gear, the higher the temperature, the faster the light propagation rate, and the shorter the light propagation time.

By periodically acquiring, continuously determining the current light propagation time, the reliability of the temperature control method can be improved, and the temperature of the refrigerator storage chamber can be in a proper temperature range.

In some embodiments, the temperature control method further comprises:
s12, acquiring the current temperature control gear of the refrigerator.
In the present application, the higher the temperature control gear of the refrigerator is, the lower the corresponding temperature is, and each temperature control gear has a corresponding temperature range.
It should be noted that S11 and S12 are not strictly executed, S11 may be executed first and S12 may be executed later, S12 may be executed first and S11 may be executed later, or S11 and S12 may be executed simultaneously.

The corresponding relation between the temperature control gear of the refrigerator and the light propagation time threshold value triggering the start/stop of the compressor can be obtained through experimental detection, and the corresponding relation is preset in a temperature controller of the refrigerator before the refrigerator leaves a factory.
In some embodiments, each temperature control gear has its corresponding first and second light propagation time thresholds, the higher the temperature control gear, the lower its corresponding temperature, and the longer the corresponding first and second light propagation time thresholds.

The temperature and humidity of the gas are uneven due to the non-uniformity of the gas in the refrigerator storage chamber, the density of the gas is different, the light propagation can be influenced by the temperature, the density and the like of the gas, and the temperature of the refrigerator is controlled through the light propagation, so that the temperature control result is closer to the reality, and the reliability of the temperature control method is improved.
