[0031] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0032] Before introducing a temperature control method, device, electronic device, refrigerator, storage medium and product shown in the embodiments of the present disclosure, the application scenarios involved in the embodiments of the present disclosure are first introduced.
[0033] In order to accurately control the temperature of food, the temperature control system of the refrigerator usually adds a cooling tray based on the top temperature sensor, and the bottom temperature sensor is placed under the cooling tray to quickly obtain the temperature of food. Figure 1 , Figure 1 This is a cross-sectional schematic diagram of a thermos bucket, wherein 1 is the thermos bucket, 2 is a drawer, 3 is an air inlet, 4 is an air outlet, 5 is a top temperature sensor, 6 is a bottom temperature sensor, and 7 is a cooling tray. The top temperature sensor can be used to detect the temperature of the inner space of the thermos bucket, and the bottom temperature sensor can be used to detect the temperature of the food in the thermos bucket.
[0034] In the related art, the temperature of the internal space of the storage container is usually controlled based on the temperatures detected by the top temperature sensor and the bottom temperature sensor respectively. The temperatures detected by the top temperature sensor and the bottom temperature sensor cannot be effectively combined, resulting in poor response speed and interference suppression effect of the temperature control system.
[0035] The disclosed embodiment controls the temperature of the storage container in the refrigerator by combining the temperature of the internal space of the storage container with the temperature of the object placed in the storage container. When the food placed in the storage container changes, the temperature of the storage container can be quickly and accurately regulated, thereby improving the response speed and accuracy of temperature control.
[0036] Figure 2 is a flow chart of a temperature control method according to an exemplary embodiment. Figure 2 As shown, the method may include the following steps.
[0037] In step S101, a first actual temperature and a second actual temperature of a storage container in a refrigerator are obtained, wherein the first actual temperature represents the temperature of an inner space of the storage container, and the second actual temperature represents the temperature of an object placed in the storage container.
[0038] For example, the storage container in the refrigerator can be any independent storage space in the refrigerator, such as a refrigerator, a refrigerator drawer, a freezer, a freezer drawer, a heat preservation barrel, a temperature-changing drawer, a fresh-keeping room, a fresh-keeping drawer, etc. At least two temperature sensors can be set in the storage container, respectively used to detect the temperature of the internal space of the storage container and the temperature of the food stored in the storage container. Figure 1 Taking the thermos barrel shown as an example, the first actual temperature and the second actual temperature can be obtained by the top temperature sensor and the bottom temperature sensor respectively.
[0039] In step S102, a second target temperature is determined according to the first actual temperature and the first target temperature.
[0040] In some embodiments, the difference ΔT between the first actual temperature and the first target temperature may be calculated, and then the second target temperature may be linearly adjusted according to ΔT. The second target temperature = the first target temperature + k*ΔT, where k is an adjustment coefficient, and k may be set according to configuration parameters of different refrigerators.
[0041] In other embodiments, the first actual temperature and the first target temperature may be input into a pre-trained temperature determination model to obtain a second target temperature output by the temperature determination model.
[0042] In step S103, the temperature of the storage container is controlled according to the second target temperature and the second actual temperature.
[0043] In some embodiments, the temperature of the storage container can be dynamically adjusted by a PID controller according to the difference between the second target temperature and the second actual temperature.
[0044] In other embodiments, the temperature of the storage container may be dynamically adjusted according to the difference between the second actual temperature and the second target temperature through a fuzzy control algorithm.
[0045] In other embodiments, a pre-established MPC (Model Predictive Control) system can be used to predict the future temperature change trend of the storage container according to the difference between the second actual temperature and the second target temperature, and the temperature of the storage container can be dynamically adjusted according to the temperature change trend.
[0046] In other embodiments, the air intake of the storage container can be controlled by controlling the angle of the air door of the air inlet of the refrigerator to control the temperature of the storage container.
[0047] In summary, the present disclosure obtains a first actual temperature and a second actual temperature of a storage container in a refrigerator, wherein the first actual temperature represents the temperature of the internal space of the storage container, and the second actual temperature represents the temperature of an object placed in the storage container. Then, the second target temperature is determined according to the first actual temperature and the first target temperature, and the temperature of the storage container is controlled according to the second target temperature and the second actual temperature. The present disclosure controls the temperature of the storage container in the refrigerator by combining the temperature of the internal space of the storage container with the temperature of the object stored in the storage container. When the food placed in the storage container changes, the temperature of the storage container can be quickly and accurately regulated, thereby improving the response speed and accuracy of the temperature control.
[0048] In other embodiments, a cascade PID model may be established to control the temperature of the storage container. Figure 3 , the cascade PID model can include a first PID controller PID1, a second PID controller PID2 and an actuator. PID1 and PID2 are connected in series. PID1 can be the main controller and PID2 can be the sub-controller. R1-Y1 can be the main loop, R2-Y2 can be the sub-loop, the temperature of the internal space of the storage container (i.e., the compartment temperature) can be the main controlled object, the temperature of the object placed in the storage container can be represented by the tray temperature, and the tray temperature can be the sub-controlled object. The calculation order of the cascade PID control system can be the main loop first and then the sub-loop. The control method can use synchronous sampling control, and the sampling period of the main and sub-loops can be the same. Since the response speed of the controlled object of the sub-loop is faster, the sampling period can be selected according to the sub-loop.
[0049] The first PID controller uses PI control to cope with systems with large lags, and the second PID controller can use PD control to speed up the response of the secondary loop and enhance the cascade control effect. The discrete PID expression can be:
[0050] Wherein, k is the sampling number (0, 1, 2, …, n); e(k) is the deviation value input at the kth sampling time, e(k-1) is the deviation value input at the k-1th sampling time, and u(k) is the control signal at the kth sampling time.
[0051] In this embodiment, is the damper angle, e(k) is the deviation between the current temperature and the target temperature, and e(k-1) is the previous temperature deviation. K p is the proportionality coefficient, K i is the integration coefficient, K d is the differential parameter.
[0052] In this way, when the food storage in the storage container changes, it can first be processed by the second PID controller to timely adjust the second actual temperature, actively suppress interference, and improve the response speed of the temperature control system. The loop where the second PID controller is located can make corresponding changes according to the different settings of the loop where the first PID is located, so as to adapt to the storage requirements of different food materials, and can take into account the flexibility and stability of temperature control at the same time.
[0053] The input of the first PID controller may be the first actual temperature Y1 and the first target temperature R1, the output of the first PID controller may be the second target temperature R2, the input of the second PID controller may be the second actual temperature Y2 and the second target temperature R2, the output of the first PID controller may be the control information of the actuator, wherein the actuator may be, for example, a damper, and the control information may be the damper angle.
[0054] Accordingly, one implementation of step S102 may be: inputting the first actual temperature and the first target temperature into the first PID controller to obtain the second target temperature output by the first PID controller.
[0055] One implementation of step S103 may be: inputting the second target temperature and the second actual temperature into the second PID controller to obtain control information output by the second PID controller, and then controlling the damper angle of the refrigerator according to the control information to control the temperature of the storage container.
[0056] In other embodiments, the cascade PID model may be pre-tuned for parameters, and the parameter tuning may be achieved by the following steps: Step 1: When the loop where the first PID controller is located is open, determine the first control parameter of the second PID controller.
[0057] For example, the loop where the first PID controller is located can be opened, and the second PID controller can be tuned according to the parameter tuning method of a single loop to obtain the first control parameter of the second PID controller.
[0058] Step 2: When the first control parameter is determined, the loop where the first PID controller and the second PID controller are located is controlled to close the loop to determine the second control parameter of the first PID controller.
[0059] For example, the loop where the first PID controller is located can be closed, and the first PID controller can be tuned based on the tuned second PID controller to obtain the second control parameter of the first PID controller.
[0060] Step 3: When the loops of the first PID controller and the second PID controller are both closed, determine the third control parameter of the second PID controller.
[0061] For example, when the loops where the first PID controller and the second PID controller are located are both closed loops, the first PID controller can be re-tuned according to the single-loop parameter tuning method to obtain the third control parameter of the second PID controller.
[0062] Step 4: Use the third control parameter as the control parameter of the first PID controller, and use the first control parameter as the control parameter of the second PID controller.
[0063] For example, if the control quality does not reach a preset control index when the cascade PID control is performed according to the third control parameter and the first control parameter, steps 2 to 4 may be repeatedly performed until the control index is met.
[0064] In other embodiments, the cascade PID model can dynamically adjust the control parameters during the control process. First, the first temperature difference can be determined according to the first actual temperature and the first target temperature, and the second temperature difference can be determined according to the second actual temperature and the second target temperature, and then the first control parameter and the third control parameter can be adjusted according to the first temperature difference and the second temperature difference. For example, the first control parameter and the third control parameter can be dynamically adjusted by algorithms such as fuzzy logic algorithms, neural network algorithms, genetic algorithms, and particle swarm optimization algorithms.
[0065] In summary, the present disclosure obtains a first actual temperature and a second actual temperature of a storage container in a refrigerator, wherein the first actual temperature represents the temperature of the internal space of the storage container, and the second actual temperature represents the temperature of an object placed in the storage container. Then, the second target temperature is determined according to the first actual temperature and the first target temperature, and the temperature of the storage container is controlled according to the second target temperature and the second actual temperature. The present disclosure controls the temperature of the storage container in the refrigerator by combining the temperature of the internal space of the storage container with the temperature of the object stored in the storage container. When the food placed in the storage container changes, the temperature of the storage container can be quickly and accurately regulated, thereby improving the response speed and accuracy of the temperature control.

Therefore, without departing from the teachings of each example, the first component, component, region, layer or section mentioned in the examples described herein may also be referred to as the second component, component, region, layer or section. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first" and "second" may expressly or implicitly include at least one of the features. In the description herein, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0101] In addition, the word "exemplary" is used herein to indicate serving as an example, instance, or diagram. Any aspect or design described as "exemplary" in this article is not necessarily understood to be advantageous compared to other aspects or designs. On the contrary, the use of the word exemplary is intended to present concepts in a specific way. As used herein, the term "or" is intended to represent an inclusive "or" rather than an exclusive "or". That is, unless otherwise specified or clear from the context, "X applies A or B" is intended to represent any one of the natural inclusive arrangements. That is, if X applies A; X applies B; or X applies both A and B, "X applies A or B" is satisfied under any of the aforementioned examples. In addition, unless otherwise specified or clearly pointed to a singular form from the context, the articles "one" and "an" as used in this application and the appended claims are generally understood to mean "one or more".
[0102] Likewise, although the present disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art after reading and understanding the specification and drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components (e.g., elements, resources, etc.) described above, unless otherwise indicated, the terms used to describe such components are intended to correspond to any component (functionally equivalent) that performs the specific functions of the described components, even if the structure is not equivalent to the disclosed structure. In addition, although specific features of the present disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations as may be desired and beneficial to any given or specific application. In addition, with respect to "including", "having", "having", "having", or variations thereof used in a specific embodiment or claim, such terms are intended to be inclusive in a manner similar to the term "comprising".
[0103] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any modification, use or adaptation of the present disclosure, which follows the general principles of the present disclosure and includes common knowledge or customary techniques in the art that are not disclosed in the present disclosure. The specification and examples are intended to be exemplary only, and the true scope and spirit of the present disclosure are indicated by the appended claims.
[0104] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
