The various embodiments provided are intended to explain the present invention, not to limit the present invention. In fact, it will be apparent to those skilled in the art that various modifications and variations may be made to the present invention without departing from the scope or spirit of the present invention. For example, a feature illustrated or described as a part of one embodiment may be used together with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover such modifications and variations within the scope of the appended claims and their equivalents.

[0051] Refer to the following Figures 1 to 4The refrigerator 10 and the defrosting control method thereof according to the embodiment of the present invention are described. The directions or positional relationships indicated by "upper", "lower", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. To facilitate the illustration of the structure of the device, some of the drawings of the present invention are illustrated in perspective.

[0052] In the description of this embodiment, it should be understood that the term "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined. When a feature "includes or contains" one or some of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may further include other features.

[0053] In the description of the present embodiment, the description with reference to the terms "one embodiment", "some embodiments", "some examples", "an example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0054] In one aspect, the present invention provides a refrigerator 10, Figure 1 1 is a schematic structural diagram of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 of this embodiment should be understood in a broad sense. For example, it can be a storage device with a fresh-keeping function such as a refrigerator 10, a freezer, or a refrigerator.

[0055] The refrigerator 10 may generally include a box body 100 and a door body (not shown in the figure), the box body 100 defines one or more storage compartments 110 inside, the storage compartments 110 may be configured as refrigeration compartments, freezing compartments or variable temperature compartments according to the refrigeration temperature, the door body corresponds to the number of storage compartments 110, and is used to open and close each storage compartment 110. Specifically, the number, function, layout, etc. of the storage compartments 110 may be configured in a targeted manner according to actual needs.

[0056] The refrigerator 10 may further include a thawing device 200, which is disposed in the storage compartment 110 and has a thawing compartment 211 for placing food. When the thawing device 200 is started, the thawing device 200 may generate a thawing airflow in the thawing compartment 211, and utilize the thawing airflow to continuously exchange heat with the food, thereby rapidly thawing the food.

[0057] In an optional embodiment, the thawing device 200 may include a thawing box 210, a flow promotion component 220, a heating component 230, a humidification component 240, a measurement component 250, and the like.

[0058] The thawing chamber 211 is formed inside the thawing box 210, and the flow promoting component 220, the heating component 230, the humidifying component 240 and the measuring component 250 can be arranged in the thawing chamber 211. A thawing area is defined in the thawing space, and a tray 212 is placed in the thawing area. For example, the thawing area can be located at the bottom of the thawing chamber 211, or can be located on a shelf in the thawing chamber 211.

[0059] The flow promoting assembly 220 may include an axial flow fan, which may be arranged toward the thawing area to generate a thawing airflow. By further optimizing the internal structure of the thawing chamber 211, the thawing airflow may circulate through the food. This helps to improve the flow smoothness of the thawing airflow and increase the heat exchange rate between the thawing airflow and the food.

[0060] The heating component 230 may include a heating tube or a heating plate, which may be disposed on the air supply path between the flow-promoting component 220 and the thawing area, and is used to heat the thawing airflow so that the airflow temperature of the thawing airflow is controlled within a preset range to ensure heat exchange efficiency and prevent the surface of the food from being cooked due to the thawing airflow being too high. In order to alleviate the heating tube or the heating plate from hindering the flow of the thawing airflow, the heating tube may be bent into a ring shape or grille holes may be opened on the heating plate to allow the thawing airflow to pass smoothly.

[0061] The humidifying assembly 240 may include a water storage box 241 and an atomizing head 242. The water storage box 241 is mainly used to store humidifying water. The atomizing head 242 is connected to the inside of the water storage box 241 to convert the humidifying water into a humidifying airflow and supply it to the thawing chamber 211, thereby adjusting the internal humidity of the thawing chamber 211 to prevent the surface of the food from being dried. Furthermore, the humidifying assembly 240 may also include a heating wire 243, which is arranged in the water storage box 241 and is used to adjust the temperature of the humidifying water.

[0062] The measuring component 250 may include a gravity sensor and / or an infrared sensor, which can collect information such as the weight, volume, or height of the food, so as to specifically adjust the airflow parameters of the thawing airflow and reasonably control the thawing time of the food. Of course, the measuring component 250 may also be a scale or marking line with a scale, so that the user can estimate the height of the food by visual inspection.

[0063] Of course, the above examples are merely illustrative. Based on the understanding of the above embodiments, those skilled in the art should be able to easily expand and transform the thawing device 200 of this embodiment and adopt other types of flow promotion components 220, heating components 230, humidification components 240 or measurement components 250, etc.

[0064] It should be noted that the airflow parameters of the thawing airflow may include airflow temperature, airflow humidity and airflow speed, wherein the airflow temperature can be controlled by adjusting the power of the heating tube or heating plate, the airflow humidity can be controlled by adjusting the power of the atomizing head 242, and the airflow speed can be controlled by adjusting the power of the axial flow fan.

[0065] In one example, the air flow temperature of the thawing air flow blowing to the food may be 18° C. to 30° C., the air flow humidity may be 60% to 85%, and the air flow speed may be 1.0 m / s to 2.5 m / s.

[0066] In an optional embodiment, the storage compartment 110 where the thawing device 200 is located is the refrigerating compartment of the refrigerator 10, and the thawing box 210 has an insulation layer to isolate the temperature difference. In this way, during the thawing process, the internal temperature of the refrigerating compartment will not be affected, and other food in the compartment can be refrigerated and preserved normally.

[0067] The thawing chamber 211 may be provided with an ambient temperature sensor 260, an ambient humidity sensor 270 and a food temperature sensor 280, wherein the ambient temperature sensor 260 and the ambient humidity sensor 270 may be used to detect the ambient temperature and ambient humidity of the thawing space respectively, so as to ensure that the food is thawed at a suitable ambient temperature and ambient humidity. The food temperature sensor 280 may be used to detect the surface temperature of the food, to prevent the food from being cooked due to excessively high surface temperature, and to ensure the thawing quality of the food.

[0068] In addition, a water level sensor, a temperature control switch 244 and a battery 245 may be provided in the water storage box 241. The water level sensor is mainly used to detect the height of the humidification water in the water storage box 241 so that the user can be informed in time and replenish water when the humidification water is less. The temperature control switch 244 is connected to the heating wire 243 and the battery 245, and is used to disconnect in time when the humidification water is less or there is no humidification water, so as to prevent the heating wire 243 from drying out. In this way, the safety and reliability of the thawing device 200 can be improved.

[0069] Figure 3 is a schematic block diagram of a refrigerator 10 according to an embodiment of the present invention.

[0070] like Figure 3As shown, the refrigerator 10 of the embodiment of the present invention further includes a controller 300. The controller 300 includes a processor 310 and a memory 320. The memory 320 stores a machine executable program 321. When the machine executable program 321 is executed by the processor 310, it is used to implement the defrosting control method in any of the following embodiments.

[0071] The memory 320 may include a memory and a non-volatile memory 320 (non-volatile memory), and provide execution instructions and data to the processor 310. Exemplarily, the memory may be a high-speed random access memory 320 (Random-Access Memory, RAM), and the non-volatile memory 320 may be at least one disk storage 320.

[0072] In this embodiment, the processor 310 is an integrated circuit chip that has the ability to process signals. The processor 310 can be a general-purpose processor 310, such as a central processing unit 310 (CPU), a network processor 310 (NP), a digital signal processor 310 (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, microprocessors 310, and any other conventional processors 310.

[0073] Another aspect of the present invention provides a thawing control method for a refrigerator 10 .

[0074] Figure 4 is a schematic diagram of a defrosting control method of a refrigerator 10 according to an embodiment of the present invention.

[0075] like Figure 4 As shown, the defrosting control method of the refrigerator 10 according to the embodiment of the present invention may generally include:

[0076] Step S402, responding to the instruction to thaw the food.

[0077] Among them, the thawing instruction can be sent remotely by the user through a mobile device (such as a mobile phone, a tablet, etc.), or it can be directly generated by the user controlling the display screen of the refrigerator 10. The thawing instruction is used to instruct the refrigerator 10 to start the thawing process. In this embodiment, the thawing instruction may include the type of ingredients selected by the user, such as chicken, fish, beef, etc. In some other embodiments, the thawing device 200 can be equipped with an identification component, and after the thawing process is started, the identification component can automatically identify the type of ingredients.

[0078] Step S404, obtaining the target thawing temperature of the thawing chamber 211 and the target thawing time of the food.

[0079] Among them, the target thawing temperature refers to the optimal thawing temperature required for thawing ingredients, and the target thawing time refers to the optimal thawing time required for thawing ingredients.

[0080] In an optional embodiment, when obtaining the target thawing temperature of the thawing chamber 211 and the target thawing time of the food, the amount of the food (the amount of the food includes one or more of volume, height, and weight) can be obtained through the measuring component 250, the initial temperature of the food can be obtained through the food temperature sensor 280, and the initial temperature of the thawing chamber 211 can be obtained through the ambient temperature sensor 260. When the type of food is known, the target thawing temperature of the thawing chamber 211 and the target thawing time of the food can be matched from the pre-stored relationship table according to the amount of food, the initial temperature of the food, and the initial temperature of the thawing chamber 211.

[0081] Step S406, starting the thawing device 200 to maintain the thawing chamber 211 at the target thawing temperature.

[0082] The heating component 230 of the thawing device 200 shown in this embodiment is independent of the flow promoting component 220. However, in some other embodiments, the heating component 230 of the thawing device 200 may also be attached to the flow promoting component 220, that is, the heating component 230 is a part of the flow promoting component 220, so that the flow promoting component 220 has a heating function.

[0083] The step of starting the thawing device 200 may be to start the flow promotion component 220, the heating component 230 and the humidification component 240 respectively. The flow promotion component 220 is used to start blowing the thawing airflow toward the food to be thawed, so that the thawing airflow circulates through the food. The heating component 230 is used to start heating the thawing airflow, so as to maintain the thawing chamber 211 at the target thawing temperature, thereby improving the heat exchange efficiency between the thawing airflow and the food. The humidification component 240 is used to supply the humidified airflow toward the thawing chamber 211, so as to adjust the internal humidity of the thawing chamber 211, maintain the surface of the food moist, and prevent the food from being dried.

[0084] In order to avoid large fluctuations in the internal temperature of the thawing chamber 211, when the humidifying component 240 is started, the heating wire 243 of the humidifying component 240 can be used to heat the humidification water to increase the temperature of the humidification water so that the air flow temperature of the humidified air flow blown out from the atomizing head 242 is the same as the target thawing temperature of the thawing chamber 211.

[0085] It is worth noting that before starting the humidification component 240, the water level of the humidification water can be detected by the water level sensor in the water storage box 241, and the humidification component 240 is started only when the water level of the humidification water meets the requirement. This is to prevent insufficient humidification water and avoid dry burning of the heating wire 243.

[0086] In an optional embodiment, when maintaining the thawing chamber 211 at the target thawing temperature, the flow promotion component 220 can be controlled to operate at a first speed. When the thawing chamber 211 reaches the target thawing temperature, the flow promotion component 220 can be controlled to operate at a second speed, wherein the second speed is greater than the first speed.

[0087] That is to say, the flow promotion component 220 initially runs at a relatively low speed, the air flow speed is relatively slow, and the heat generated by the heating component 230 can be slowly blown by the thawing air flow to various areas of the thawing chamber 211. In this way, it is beneficial to quickly raise the thawing chamber 211 to the target thawing temperature and accelerate the thawing process. Afterwards, the flow promotion component 220 runs at a relatively high speed, the air flow speed is relatively fast, and the thawing air flow can quickly exchange heat with the food, thereby improving the heat exchange efficiency and further accelerating the thawing process.

[0088] Step S408, obtaining the startup time of the thawing device 200.

[0089] In an optional embodiment, the thawing device 200 may be equipped with a timing component, which may be disposed in the thawing chamber 211, or in the storage chamber 110 of the refrigerator 10, or outside the refrigerator 10. When the thawing device 200 is started, the timing component is started synchronously, and the timing component is used to accumulate the startup time of the thawing device 200. When obtaining the startup time of the thawing device 200, the accumulated value of the timing component may be directly obtained.

[0090] Step S410, when the startup time reaches the target thawing time, the thawing device 200 is turned off.

[0091] It can be understood that the difference between the startup time and the target thawing time is used as a shutdown condition of the thawing device 200. When the startup time reaches the target thawing time, the thawing device 200 can be automatically triggered to shut down without user intervention.

[0092] In an optional embodiment, when shutting down the thawing device 200, the heating component 230 and the humidifying component 240 can be shut down first, the operation and loading of the flow promotion component 220 can be maintained, and then the real-time temperature and real-time humidity of the thawing chamber 211 can be obtained. When the real-time temperature is lower than the preset temperature threshold and the real-time humidity is lower than the preset humidity threshold, the flow promotion component 220 can be shut down.

[0093] When the food is thawed, the interior of the thawing chamber 211 is relatively humid, which is not only easy to breed bacteria and affect the next thawing, but also easy to cause corrosion and rust of the components, shortening the service life of the thawing device 200. Therefore, after turning off the heating component 230 and the humidifying component 240, by maintaining the operating state of the flow promotion component 220, the thawing airflow generated by it can dry the interior of the thawing chamber 211, which can effectively prevent bacterial growth, component corrosion and rust.

[0094] According to the thawing control method of the refrigerator 10 of the present invention, when responding to the thawing instruction of the food, the target thawing temperature of the thawing chamber 211 and the target thawing time of the food are first obtained, and then the thawing device 200 is started to maintain the thawing chamber 211 at the target thawing temperature, and then the start-up time of the thawing device 200 is obtained. When the start-up time reaches the target thawing time, the thawing device 200 is turned off. In this way, incomplete thawing or over-thawing of the food can be avoided, which is conducive to ensuring the thawing quality of the food and improving the user experience.

[0095] In some special cases, such as when the timing component fails, the timing may stop, causing the accumulated value to never reach the target thawing time. The thawing device 200 will continue to run and cannot be automatically shut down, causing the food to be over-thawed.

[0096] To solve the above problem, in another embodiment, after maintaining the thawing chamber 211 at the target thawing temperature, the real-time temperature and expected temperature of the food can be obtained, and when the real-time temperature of the food reaches the expected temperature, the thawing device 200 is closed.

[0097] It can be understood that in this embodiment, the difference between the real-time temperature of the food and its expected temperature is used as another closing condition of the thawing device 200. When the real-time temperature of the food reaches the expected temperature, the thawing device 200 can also be automatically triggered to close without user participation.

[0098] The expected temperature of the food refers to the surface temperature of the food when it is thawed to the optimal state, which can be obtained synchronously with the target thawing temperature of the thawing chamber 211 and the target thawing time of the food.

[0099] In an optional embodiment, when obtaining the expected temperature of the food, the amount of the food, the initial temperature of the food and the initial temperature of the thawing chamber 211 can be obtained. When the type of the food is known, the expected temperature of the food is matched from a pre-stored relationship table based on the amount of the food, the initial temperature of the food and the initial temperature of the thawing chamber 211.

[0100] In this way, the closing timing of the thawing device 200 can be flexibly controlled. When one of the timing components or the food temperature sensor 280 fails, the thawing device 200 can still be closed normally, thereby improving the reliability of the thawing device 200 and avoiding food thawing failure.

[0101] In an optional embodiment, during the process of starting the thawing device 200, the thawing control method also includes: obtaining change data of the food within a preset time period; if the change data does not meet the thawing expectations of the food within the preset time period, redetermining the thawing parameters based on the change data; and controlling the thawing device 200 to thaw the food with the redetermined thawing parameters.

[0102] Among them, the preset duration refers to the pre-set time for obtaining change data, for example, it can be 10 minutes after the start of thawing, or it can be 20 minutes after the start of thawing. The preset duration can also include multiple acquisition time points. For example, within 1 hour after the start of thawing, every 15 minutes is used as an acquisition time point, and one hour includes 4 acquisition time points.

[0103] The change data may refer to the state data of the food material itself, for example, the state data may be the color, humidity, temperature, weight, shape, etc. of the food material.

[0104] Thawing expectation refers to the expected state that the food needs to reach after reaching the target thawing time. Specifically, thawing expectation can be the expected temperature that the food itself needs to reach when the food reaches the target thawing time.
