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.

[0047] Refer to the following Figures 1 to 4 The 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 “outside”, “upper”, “lower”, “top”, “bottom”, “horizontal”, and “vertical” 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.

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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] The refrigerator 10 may further include a thawing device 200, which is disposed in the storage compartment 110 and has a thawing space 211 for placing food to be thawed. When the thawing device 200 is started, the thawing device 200 may generate a thawing airflow in the thawing space 211, and continuously exchange heat between the thawing airflow and the food, thereby rapidly thawing the food.

[0053] 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.

[0054] The thawing box 210 has a thawing space 211 formed inside, 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 space 211. A thawing area is defined in the thawing space 211, and a tray 212 for placing food is arranged in the thawing area. For example, the thawing area can be located at the bottom of the thawing space 211, or can be located on a shelf in the thawing space 211.

[0055] The flow-promoting component 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 space 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.

[0056] 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.

[0057] The humidification component 240 may include a water storage box 241 and an atomization head 242. The water storage box 241 is mainly used to store humidification water. The atomization head 242 is connected to the inside of the water storage box 241 to convert the humidification water into a humidification airflow and supply it to the thawing space 211, thereby adjusting the internal humidity of the thawing space 211 to prevent the surface of the food from being dried. Further, the humidification component 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 humidification water.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] In an optional embodiment, the storage compartment 110 where the thawing device 200 is located can be a variable temperature compartment of the refrigerator 10. The food to be thawed can be placed in the thawing device 200 in advance for frozen storage. When the food needs to be eaten, the thawing device 200 can be controlled in advance to thaw the food, thereby avoiding long waiting.

[0063] The thawing space 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 211, respectively, 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.

[0064] 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.

[0065] Figure 3 is a schematic block diagram of a refrigerator 10 according to an embodiment of the present invention.

[0066] like Figure 3 As 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.

[0067] 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.

[0068] 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.

[0069] Another aspect of the present invention provides a thawing control method for a refrigerator 10 .

[0070] Figure 4 is a schematic diagram of a defrosting control method of a refrigerator 10 according to an embodiment of the present invention.

[0071] like Figure 4 As shown, the defrosting control method of the refrigerator 10 according to the embodiment of the present invention may generally include:

[0072] Step S402, receiving a thawing instruction issued by a user.

[0073] In this step, the thawing instruction can be sent remotely by the user through a mobile device (such as a mobile phone, tablet, etc.); of course, it can also be generated directly by the user controlling the display screen of the refrigerator 10.

[0074] Step S404 , raising the internal temperature of the storage compartment 110 to a target temperature.

[0075] In this step, the target temperature should be lower than -1°C, for example, -2°C, -3°C, -5°C, etc., in order to keep the food frozen at a higher freezing temperature.

[0076] Step S406, starting the thawing device 200, and using the thawing airflow generated by the thawing device 200 to thaw the food.

[0077] In this step, the thawing airflow thaws the food through heat exchange, which can not only speed up the thawing speed of the food and improve the uniformity of thawing, but also prevent the surface of the food from being cooked.

[0078] The thawing control method of the refrigerator 10 of the present invention, upon receiving the thawing instruction issued by the user, first raises the internal temperature of the storage compartment 110 to the target temperature. In this way, the food can be frozen and stored at a relatively high freezing temperature, which is beneficial to reducing the refrigeration energy consumption of the storage compartment 110 and the subsequent thawing energy consumption of the food. When the thawing device 200 is started, the thawing airflow generated by the thawing device 200 can continuously exchange heat with the food, thereby completing the thawing of the food in advance, so that the user can use the frozen food immediately after returning home without waiting, which is beneficial to saving the user's time cost and improving the user's use experience.

[0079] In an optional embodiment, the thawing instruction includes the thawing time selected by the user. Before the step of starting the thawing device 200, it can be determined whether the current time has reached the thawing time selected by the user. If the determination result is yes, the step of starting the thawing device 200 is executed.

[0080] For example, if the thawing time selected by the user is 5:00 p.m., and the current time is 4:30 p.m., then it is still necessary to wait for the food to be frozen and stored at the target temperature to prevent premature thawing until 5:00 p.m., and then start the thawing device 200. In this way, the food can be prevented from being in a thawing state for a long time, and the growth of bacteria can be prevented from affecting the quality or freshness of the food.

[0081] In an optional embodiment, the step of increasing the internal temperature of the storage compartment 110 to the target temperature includes: reducing the supply amount of the refrigeration airflow and / or increasing the airflow temperature of the refrigeration airflow.

[0082] Generally speaking, the normal freezing temperature of food is about -18°C. When thawing, if it starts from -18°C, it will take a relatively long time. In this embodiment, the internal temperature of the storage compartment 110 is raised to the target temperature (for example, -1°C) in advance, so that the food can be frozen and stored at a higher freezing temperature. In this way, when thawing, the food can be thawed from -1°C, which is conducive to shortening the thawing time. Reducing the supply of refrigeration airflow or increasing the airflow temperature of the refrigeration airflow can reduce the refrigeration energy consumption of the refrigerator 10 and the subsequent thawing energy consumption of the food to a certain extent.

[0083] It should be noted that in some special cases, for example, the thawing time selected by the user is 5:00 pm, and the current time is 4:28 pm, and the time difference between the current time and the thawing time is only 2 minutes. In such a short time, it is difficult to raise the internal temperature of the storage compartment 110 to the target temperature by reducing the supply of refrigeration airflow and increasing the airflow temperature of the refrigeration airflow, resulting in the inability to thaw the food on time.

[0084] To solve the above problem, in this embodiment, the priority order of program execution can be set. When the current time reaches the thawing time selected by the user, the thawing device 200 must be started immediately even if the internal temperature of the storage compartment 110 has not been raised to the target temperature.

[0085] In an optional embodiment, the thawing instruction includes the type of food selected by the user. After the step of starting the thawing device 200, the thawing time of the food can be set according to the type of food, and then the start-up time of the thawing device 200 is accumulated. When the start-up time of the thawing device 200 reaches the thawing time of the food, the thawing device 200 is shut down.

[0086] The optimal thawing time required for different types of ingredients will vary. By selecting the type of ingredients and setting the thawing time accordingly, you can prevent the ingredients from being over-thawed, ensure the thawing quality of the ingredients, and reduce unnecessary thawing energy consumption.

[0087] In this embodiment, the types of ingredients and the corresponding thawing times may be pre-stored in a corresponding relationship table. After the user selects the type of ingredient, the corresponding thawing time may be automatically retrieved from the relationship table.

[0088] Furthermore, after receiving the thawing instruction issued by the user, if it is found that the user has not selected the type of food in the thawing instruction, a prompt message prompting the user to select the type of food can be fed back. Alternatively, the thawing device 200 itself has an image recognition component, which automatically recognizes the type of food by using the image recognition component to replace the user's manual selection, making the thawing operation more intelligent.

[0089] In another optional embodiment, the thawing instruction may include a thawing time selected by the user. After starting the thawing device 200, the start-up time of the thawing device 200 may be accumulated. When the start-up time reaches the thawing time, the thawing device 200 is shut down.

[0090] That is to say, the user can directly set the thawing time manually, so as to control the food to be in a completely thawed state or a semi-thawed state. For example, when the food needs to be cut, it is not conducive to the cutting operation if the food is completely thawed or completely frozen. At this time, it is particularly important to control the food to be in a semi-thawed state.

[0091] In one example, the thawing device 200 may have a timer, which may be disposed in the thawing space 211 of the thawing device 200, or in the storage compartment 110 of the refrigerator 10, or outside the refrigerator 10. After the thawing device 200 is started, the timer is started at the same time, thereby accumulating the start-up time of the thawing device 200.

[0092] In a preferred embodiment, after the step of starting the thawing device 200, the surface temperature of the food can also be detected. When the surface temperature of the food reaches the desired thawing temperature, the thawing device 200 is shut down.

[0093] In the experimental stage, the surface temperature of different ingredients in a completely thawed state can be measured through a large amount of data, and the surface temperature can be used as the expected thawing temperature of the ingredients. In the actual thawing process, when the surface temperature of the ingredients rises to the expected thawing temperature, it can be indicated that the ingredients have been completely thawed, and the thawing device 200 can be shut down at this time.

[0094] Preferably, the surface temperature of the food and the thawing time can be used together as the control basis for shutting down the thawing device 200. In some special cases, such as when the timer fails, resulting in the cumulative start time failing to reach the thawing time, and the food temperature sensor 280 detects that the surface temperature of the food has reached the desired thawing temperature, the thawing device 200 can be shut down. For another example, when the food temperature sensor 280 fails, resulting in the measured surface temperature of the food being too far off, and the cumulative start time of the timer has reached the thawing time, the thawing device 200 can be shut down.

[0095] That is to say, when one of the surface temperature of the food and the thawing time meets the condition, the thawing device 200 can be turned off. In this way, the reliability of the thawing device 200 can be improved, and the food can be prevented from being over-thawed due to the failure of the timer or the food temperature sensor 280.

[0096] In an optional embodiment, during the process of starting the thawing device 200, the volume, height, and weight of the food are detected, and then the airflow parameters of the thawing airflow are adjusted according to the volume, height, and weight of the food. The airflow parameters include one or more of the following: airflow temperature, airflow humidity, and airflow speed.

[0097] The shape of the ingredients can be learned by detecting the volume, height and weight of the ingredients. For flaky ingredients, if the airflow velocity of the thawing airflow is high, the ingredients will be easily dried. For block ingredients, if the airflow velocity of the thawing airflow is low, the blowing force is not enough, making it difficult to thaw the center of the ingredients. For flaky ingredients and block ingredients of the same weight, since the contact area between the flaky ingredients and the thawing airflow is large and the heat exchange efficiency is better, the thawing time required for complete thawing is also different from that of block ingredients. Therefore, it is particularly important to detect the volume, height and weight of the ingredients to learn the shape of the ingredients, and to reasonably adjust the airflow temperature, airflow humidity and airflow velocity of the thawing airflow.

[0098] After shutting down the thawing device 200, a prompt message for prompting the completion of thawing can also be sent to the user. The prompt message can be fed back to the user in the same way as the user sends the thawing instruction, so as to promptly inform the user that the food has been thawed and please take it in time.

[0099] Furthermore, the temporary storage time after the food is thawed can be set. If the food is not taken out within the temporary storage time, the internal temperature of the storage chamber 110 can be restored to the initial temperature so that the food is re-frozen. It can be understood that if the food is in a thawed state for a long time, its surface is easy to be dried, easy to breed bacteria, and even rot and deteriorate to emit an unpleasant odor. By refreezing the food, it is conducive to reasonable control of the food and avoid food waste.

[0100] It is worth noting that after receiving the thawing instruction, it is also possible to detect whether the door of the storage compartment 110 where the thawing device 200 is located is in a closed state. If it is determined that the door is in a closed state, the temperature of the storage compartment 110 is increased to the target temperature.

[0101] The thawing device 200 can be arranged in the storage compartment 110 in the form of a drawer, or can be directly placed in the storage compartment 110 in an accessible manner. The latter includes arranging the thawing device 200 on the inner side of the door body, and the main control device of the refrigerator 10 supplies power to the various components of the thawing device 200.

[0102] After the thawing device 200 is started, if the door of the storage compartment 110 is found to be opened, the thawing device 200 can be shut down, the startup time at this time can be recorded, and after the door is closed, the thawing device 200 can be restarted and the startup time can be continuously accumulated. In this way, the safety of electricity use can be improved.

[0103] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
