[0002] In daily life, using the refrigerator's cold storage room to defrost food can preserve the food's nutrients and prevent the growth of microorganisms and bacteria during the thawing process. Different food ingredients have different internal structures and nutrients, so different types of food ingredients of the same weight require different thawing times.

[0003] In the related art, an electric field generating device is provided in the thawing device, which promotes the polarization of water molecules in the food through the electric field, and generates frictional heat to accelerate the thawing speed of the food. The common thawing method is to determine the thawing time according to the quality of the food, but this method cannot set the appropriate thawing time according to the type of food, which can easily lead to excessive thawing and loss of nutrients. In order to solve the above problems, an intelligent sensor is set to identify the shape, height, texture, etc. of the food to determine the type of food, thereby determining the thawing time of the food.

[0039] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, the characteristics, operations or features described in the specification can be combined in any appropriate manner to form various implementation methods. At the same time, the steps or actions in the method description can also be replaced or adjusted in order in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the accompanying drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a necessary sequence, unless otherwise specified that a certain sequence must be followed.

[0040] In the description of this application, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0041] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0042] The rapid and nutritious thawing of food ingredients is a major pain point in people's lives today. If frozen food ingredients are placed in a natural environment to thaw, the thawing time required is long, which greatly delays the cooking time; in addition, microorganisms and bacteria are easily bred during the thawing process, and the thawing effect is not good. In daily life, using the refrigerator's cold storage room to thaw food ingredients can retain the nutrients of the food ingredients during the thawing process and prevent the food ingredients from breeding microorganisms and bacteria, but the thawing speed of the cold storage room is slow. If the user places the food to be thawed in the cold storage room and forgets to take it out, it will cause excessive loss of the juice of the food ingredients. In addition, different food ingredients have different internal composition structures and different nutritional components, so different types of food ingredients of the same weight require different thawing times. Therefore, how to reasonably control the thawing time of food ingredients and ensure that the food ingredients can retain nutrients without loss after thawing is a problem that needs to be solved at present.

[0043] In the related art, an electric field generating device is provided in the thawing device, which promotes the polarization of water molecules in the food through the electric field, and generates frictional heat to accelerate the thawing speed of the food. The common thawing method is to determine the thawing time according to the quality of the food, but this method cannot set the appropriate thawing time according to the type of food, which can easily lead to excessive thawing and loss of nutrients. In order to solve the above problems, an intelligent sensor is set to identify the shape, height, texture, etc. of the food to determine the type of food, thereby determining the thawing time of the food. However, due to the similar shapes of meat ingredients, it is easy to identify inaccurately, resulting in inaccurate thawing time and poor thawing effect of the food.

[0044] Based on this, the embodiments of the present application provide a thawing device, a thawing method, a controller and a readable storage medium thereof, which improve the accuracy of predicting the thawing time of food, thereby improving the thawing effect of food.

[0045] Reference Figure 1 As shown, Figure 1 1 is a schematic diagram of a thawing device provided in an embodiment of the present application, wherein the thawing device comprises a thawing drawer 1000, an electric field generating device, an air supply device 130, a weight sensor 200 and a controller, wherein an upper cover plate 100 is provided at the opening of the thawing drawer 1000; the electric field generating device is arranged on the upper cover plate 100, and the electric field generating device is used to generate an electric field to the inside of the thawing drawer 1000; the air supply device 130 is arranged on the upper cover plate 100, and the air supply device 130 is used to supply air to the inside of the thawing drawer 1000; the weight sensor 200 is used to obtain the mass of the food to be thawed. The controller is used to obtain the type of food to be thawed determined by the user and the mass of the food to be thawed determined by the weight sensor 200, and determine the target thawing time according to the type of food to be thawed and the mass of food to be thawed, and is also used to respond to the thawing instruction and start the air supply device 130 and the electric field generating device to thaw the food to be thawed according to the target thawing time.

[0046] By having the user determine the type of food to be thawed, the accuracy of determining the type of food to be thawed can be improved compared to the prior art in which the type of food to be thawed is determined only by an intelligent sensor. The target thawing time is determined based on the type of food to be thawed determined by the user and the mass of the food to be thawed determined by the weight sensor 200, and a suitable thawing time can be provided according to the type and mass of the food, thereby improving the accuracy of the prediction of the thawing time of the food, avoiding excessive or incomplete thawing of the food, retaining the nutritional components of the food, and improving the thawing effect of the food. An electric field generating device is provided in the thawing drawer 1000, which promotes the polarization of water molecules in the food through the electric field, generates heat through friction, and accelerates the heat exchange efficiency between the food and the ambient air through the air supply device 130, thereby accelerating the thawing speed of the food.

[0047] The thawing drawer 1000 has a certain volume for placing the food to be thawed. In some embodiments of the present application, an upper cover plate 100 is provided at the opening of the thawing drawer 1000, and an electric field generating device and an air supply device 130 are provided at the upper cover plate 100. The electric field generating device is used to generate an electric field inside the thawing drawer 1000. It can be understood that the electric field generating device releases high-energy particles to exchange heat with the food by generating an electric field, promotes the polarization of water molecules in the food to be thawed placed in the thawing drawer 1000, accelerates heat transfer, and accelerates the thawing process of the food. At the same time, the electric field generated by the electric field generating device can also change the distribution of water molecules inside the food, promote some free water in the food to combine with the amino acid residues in the meat protein, and form a tightly bound water, thereby effectively reducing the loss of water in the food during the thawing process. Thawing the food using the electric field generated by the electric field generating device is a penetrating thawing method, which can well retain the nutrients of the food without loss, and improve the thawing effect of the food. During the thawing process of food, the air supply device 130 is used to supply air to the inside of the thawing drawer 1000, accelerate the convection rate inside the thawing drawer 1000, and accelerate the thawing process of food. Specifically, the air supply device 130 supplies air to the inside of the thawing drawer 1000 to accelerate the heat exchange between the food to be thawed and the ambient air, quickly reduce the temperature difference between the temperature of the food to be thawed and the ambient temperature, and promote the rapid thawing of the food to be thawed.

[0048] By arranging an electric field generating device and an air supply device 130 to cooperate with each other on the upper cover plate 100 of the thawing drawer 1000, the electric field generated by the electric field generating device acts on the food to be thawed and the air supply device 130 supplies air to the inside of the thawing drawer 1000, so that the food to be thawed placed in the thawing drawer 1000 can be quickly thawed, which greatly shortens the thawing time of the food to be thawed. At the same time, it can also ensure that the nutrients of the food to be thawed are retained and not lost during the thawing process, thereby improving the thawing effect.

[0049] In some embodiments of the present application, the bottom of the thawing drawer 1000 includes a metal plate for heat transfer, and the surface of the metal plate is provided with a reference area 300 for prompting the user to place the food to be thawed, and the food to be thawed is placed in the reference area 300. It can be understood that the reference area 300 is arranged in the center of the surface of the metal plate, and the reference area 300 is directly opposite to the position of the electric field generating device and the air supply device 130. The electric field generated by the electric field generating device ionizes high-speed moving high-energy particles. The high-energy particles collide with the surface of the food to be thawed placed in the reference area 300, which can accelerate the movement of water molecules on the surface of the food, thereby accelerating the thawing of the food. At the same time, since the food to be thawed is placed in the reference area 300, setting the weight sensor 200 in the reference area 300 can more accurately measure the mass of the food to be thawed, thereby improving the accuracy of the weight sensor 200 in determining the mass of the food to be thawed, thereby making it possible to accurately determine the target thawing time based on the mass of the food to be thawed determined by the weight sensor 200 and the type of food to be thawed determined by the user, thereby avoiding excessive or incomplete thawing of the food and improving the thawing effect of the food.

[0050] It should be noted that, in some embodiments of the present application, the metal plate for heat transfer at the bottom of the thawing drawer 1000 can be arranged at the central position of the bottom of the thawing drawer 1000, or the metal plate is arranged at the position corresponding to the reference area 300 at the bottom of the thawing drawer 1000, or the bottom of the thawing drawer 1000 is completely composed of a metal plate. It is understandable that the metal plate has good heat conduction properties. By conducting a part of the cold in the thawing drawer 1000 to the outside of the thawing drawer 1000 through the metal plate, the heat exchange between the inside and the outside of the drawer can be quickly completed, the heat convection rate is improved, and the process of thawing food is accelerated. The metal plate can be a fin plate, the flat side of the fin plate faces the inside of the thawing drawer 1000, and the side provided with fins faces the outside of the thawing drawer 1000. By providing a plurality of fins, the contact area between the metal plate and the external environment of the thawing drawer 1000 is increased, so that the process of heat exchange between the inside and outside of the thawing drawer 1000 can be further accelerated, and the thawing of food can be accelerated.

[0051] Reference Figure 2 , Figure 21 is a schematic diagram of the structure of an upper cover plate 100 provided in an embodiment of the present application, wherein an electric field generating device and an air supply device 130 are provided at the upper cover plate 100, wherein the electric field generating device comprises an arc electrode 110 and a power supply 120 for supplying power to the arc electrode 110, both ends of the arc electrode 110 are respectively connected to the power supply 120, and the air supply device 130 is provided at the inner circle of the arc electrode 110. In some embodiments of the present application, the electric field generating device further comprises at least one power supply 120, and the power supply 120 may be an independently provided high-voltage power supply 120 dedicated to supplying power to the arc electrode 110. The arc electrode 110 is made of stainless steel. The arc electrode 110 is connected to the high-voltage power supply 120 through a wire. A switch device is arranged between the arc electrode 110 and the high-voltage power supply 120. When the switch device is turned on, the high-voltage power supply 120 outputs a high-voltage current to the arc electrode 110. After the arc electrode 110 is energized, an electric field is formed that propagates toward the inside of the thawing drawer 1000. In this way, the hydrogen bonds that play a key role in the ice layer of the food can be destroyed by the high-voltage electric field, so that the ice layer structure is decomposed into a small molecular cluster structure; the high-voltage electric field can also ionize high-speed moving high-energy particles. By the high-energy particles hitting the surface of the food, the movement of water molecules on the surface of the food can be accelerated, thereby accelerating the thawing of the food; at the same time, the air supply device 130 arranged in the inner circle of the arc electrode 110 supplies air to the inside of the thawing drawer 1000, effectively accelerating the heat exchange efficiency between the food to be thawed and the ambient air. In addition, the high-voltage electric field can also promote the combination of free water in the food and amino acid residues in meat protein to form compact moisture, which can reduce the drying of the food surface and water loss caused by thawing by the air supply device 130, and retain the nutrition of the food while thawing.

[0052] It should be noted that in the embodiment of the present application, the electric field generating device is arranged at the geometric center of the upper cover plate 100, and the electric field generating device is directly opposite to the reference area 300 of the food to be thawed, which increases the contact area between the electric field and the food to be thawed, so that the electric field can better act on the surface of the food to be thawed, thereby accelerating the thawing rate. The value range of the power supply 120 in the electric field generating device is 0kV to 10kV, and the value range of the operating frequency is 10kHz to 30kHz. The embodiment of the present application does not limit the value range of the voltage of the power supply 120 and the value range of the operating frequency. Those skilled in the art can set it according to the conductivity of the arc electrode 110 and the type of food to be thawed.

[0053] It should be noted that in the embodiment of the present application, the air supply device 130 is an axial flow fan, and the air supply device 130 may also be an electric fan. The embodiment of the present application does not limit the type of the air supply device 130.

[0054] Reference Figure 3 , Figure 3is a flowchart of a thawing method provided in an embodiment of the present application, including steps S100 to S300. Specifically,

[0055] Step S100: obtaining the type of food to be thawed determined by a user and the mass of the food to be thawed determined by a weight sensor;

[0056] Step S200: determining a target thawing time according to the type and quality of the food to be thawed;

[0057] Step S300: In response to the thawing instruction, the air supply device and the electric field generating device are started to thaw the food to be thawed according to the target thawing time.

[0058] In some embodiments of the present application, the thawing method includes obtaining the type of food to be thawed determined by the user and the mass of the food to be thawed determined by the weight sensor, and determining the target thawing time according to the type of food to be thawed and the mass of the food to be thawed; the type of food to be thawed determined by the user can improve the accuracy of determining the type of food to be thawed compared to the prior art that only determines the type of food to be thawed by the intelligent sensor. The target thawing time is determined based on the type of food to be thawed determined by the user and the mass of food to be thawed determined by the weight sensor, and a suitable thawing time can be provided according to the relationship between the type and mass of the food, thereby improving the accuracy of the food thawing time prediction, avoiding excessive or incomplete thawing of the food, retaining the nutritional components of the food, and improving the thawing effect of the food. An electric field generating device and an air supply device are provided in the thawing drawer. When a thawing instruction is received, the air supply device and the electric field generating device are started to thaw the food to be thawed according to the target thawing time. The electric field generating device generates an electric field to promote the polarization of water molecules in the food and generate heat through friction. The air supply device accelerates the heat exchange efficiency between the food to be thawed and the ambient air, thereby accelerating the thawing speed of the food.

[0059] It should be noted that in some embodiments of the present application, the thawing device includes a display screen, the display screen is used to display the types of multiple ingredients for the user to choose, the display screen includes a human-computer interaction area, the user determines the type of the ingredients to be thawed by using the human-computer interaction area according to the cognition of the ingredients to be thawed, specifically, the user selects the type of ingredients to be thawed in the human-computer interaction area of ​​the display screen, and the display screen displays multiple types of ingredients in the form of a list of ingredient types for the user to choose; or the user inputs the type of ingredients to be thawed in the human-computer interaction area, and the display screen provides a text input box to recognize the text input by the user to determine the type of ingredients, or monitors the user's voice command to recognize the type of ingredients spoken by the user. Compared with only determining the type of ingredients to be thawed by identifying the texture and shape of the ingredients through the intelligent sensor, the present application can improve the accuracy of determining the type of ingredients to be thawed by the user selecting the corresponding type of ingredients to be thawed or inputting the type of ingredients to be thawed through the human-computer interaction area, so that the accuracy of the target thawing time determined according to the type of ingredients to be thawed determined by the user and the mass of the ingredients to be thawed determined by the weight sensor is improved, and the thawing effect is improved.

[0060] In some cases, the display screen may be a screen of a user terminal, the user terminal provides a human-computer interaction area by using an app or the like, and the user terminal is connected to the thawing device in a local area network or in a communication connection with the thawing device via the Internet. After the user terminal and the thawing device establish a communication connection, the user can input the type of food to be thawed through the screen of the terminal, or select the type of food to be thawed corresponding to the food to be thawed from the multiple food types displayed on the screen of the terminal, thereby providing the user with a variety of ways to determine the food to be thawed and convenience.

[0061] In some embodiments of the present application, in response to a thawing instruction, the air supply device is started to operate at a first frequency according to the target thawing time, and the electric field generating device is controlled to thaw the food to be thawed at a first voltage. In some embodiments, the value range of the first frequency can be set to 10kHz to 30kHz, so that the parameters of the air supply device are in the range of 29.4CFM to 58.83CFM, and the value range of the first voltage can be set to 1kV to 2kV. The embodiment of the present application does not limit the value range of the first frequency and the value range of the first voltage. Those skilled in the art can set the first frequency and the first voltage according to actual conditions.

[0062] Reference Figure 4 , Figure 4 1 is a flow chart of a method for determining a target thawing time according to the type and quality of food to be thawed provided by an embodiment of the present application, including steps S210 to S230. Specifically,

[0063] Step S210: matching the types of food to be thawed and the quality of the food to be thawed in a first database, wherein the first database stores a correspondence between food type, food quality, and thawing time range;

[0064] Step S220: when a corresponding relationship is matched, a reference thawing time range is determined according to the matched corresponding relationship;

[0065] Step S230: receiving a thawing time determined based on a reference thawing time range, and determining the determined thawing time as a target thawing time.

[0066] In some embodiments of the present application, determining the target thawing time according to the type of food to be thawed and the quality of the food to be thawed includes matching the type of food to be thawed and the quality of the food to be thawed in a first database, and the first database stores the correspondence between the type of food, the quality of food, and the thawing time. Therefore, matching the type of food to be thawed and the quality of food to be thawed in the first database can improve the accuracy of determining the target thawing time, reduce the loss of nutrients in food due to excessive thawing or multiple thawing caused by random selection of time by the user, and reduce the poor thawing effect.

[0067] The present application establishes a large number of common food type-food quality-defrosting time range correspondences in the first database. The correspondences are obtained through the time modeling method of the generalized linear model and the modeling verification based on the stepwise regression of the F test and the Bayesian information criterion. The present application embodiment does not limit the method of establishing the corresponding relationship between food type-food quality-defrosting time range. In the embodiment of the present application, the first database at least stores the corresponding relationship between food type-food quality-defrosting time range as shown in Table 1,

[0068] Table 1 The first database

[0069]

[0070] The type of food to be thawed determined by the user and the mass of the food to be thawed determined by the weight sensor are matched in the first database. When a corresponding relationship is matched, a reference thawing time range is determined according to the matched corresponding relationship; and the reference thawing time range is displayed on the display screen for the user to determine the target thawing time based on the reference thawing time range. The user can determine the target thawing time through the human-computer interaction area. For example, according to the user's determination that the type of food to be thawed is steak and the mass determined by the weight sensor is 150 grams, a match is made in the first database. Since there is a corresponding relationship between food type-food mass-thawing time range in the first database, the thawing time range of 15 minutes to 18 minutes is displayed on the display screen for the user to determine the target thawing time based on the reference thawing time range. After the user determines the target thawing time based on the reference thawing time range, the air supply device and the electric field generating device are started in response to the thawing instruction according to the target thawing time to thaw the food to be thawed. The electric field generating device generates an electric field to promote the polarization of water molecules in the food and generate heat through friction. The air supply device supplies air to the thawing drawer to speed up the heat exchange efficiency between the food and the ambient air, thereby speeding up the thawing speed of the food.

[0071] In some embodiments of the present application, determining the target thawing time through the human-computer interaction area includes one or more of the user selecting the target thawing time based on a reference thawing time in the human-computer interaction area, and inputting the target thawing time based on the reference thawing time in the human-computer interaction area. The embodiments of the present application do not limit the way in which the user determines the target thawing time.

[0072] It should be noted that, in some embodiments, the thawing device is provided with an interactive keypad and a rotary knob, wherein the interactive keypad includes a numeric keypad, an up button and a down button, and determining the target thawing time may also include one or more of inputting the target thawing time in the numeric keypad, determining the target thawing time by using the up button or the down button, and determining the target thawing time by twisting the rotary knob. The embodiments of the present application do not limit the method for determining the target thawing time.

[0073] Reference Figure 5 , Figure 5 is a flowchart of a method for entering an autonomous mode provided by an embodiment of the present application, including steps S240 to S260. Specifically,

[0074] Step S240: matching the types of food to be thawed and the quality of the food to be thawed in the first database, wherein the first database stores a correspondence between food type, food quality, and thawing time range;

[0075] Step S250: When no corresponding relationship is matched, the autonomous mode is entered and the user is prompted to input the target thawing time;

[0076] Step S260: Receive the target thawing time input by the user, and send the type of food to be thawed, the target thawing time and the mass of the food to be thawed determined by the weight sensor input by the user to the first database, so as to add a correspondence between the food type-food mass-thawing time range in the first database.

[0077] In some embodiments of the present application, the type of food to be thawed and the quality of the food to be thawed are matched in the first database, and the first database stores the corresponding relationship of food type-food quality-thawing time range. When the corresponding relationship cannot be matched, the autonomous mode is entered and the user is prompted to enter the target thawing time. The user can enter the target thawing time through the human-computer interaction area according to the type of food to be thawed. When the target thawing time input by the user is received, the air supply device and the electric field generating device are started to thaw the food to be thawed according to the target thawing time. The electric field generated by the electric field generating device promotes the polarization of water molecules in the food, friction heat generation, and the heat exchange efficiency between the food to be thawed and the ambient air is accelerated by the air supply device, thereby accelerating the thawing speed of the food. In addition, when the target thawing time input by the user is received, the type of food to be thawed, the target thawing time and the quality of the food to be thawed input by the user are sent to the first database, so as to add the corresponding relationship of food type-food quality-thawing time range in the first database according to the type of food to be thawed, the target thawing time and the quality of the food to be thawed.

[0078] When no corresponding relationship is matched in the first database, the autonomous mode is entered, and the corresponding relationship established by the user in the autonomous mode is uploaded to the first database, which can increase the corresponding relationship range of food type-food quality-thawing time, enrich the corresponding relationship data in the first database, and is beneficial to increase the probability that a matching relationship exists in the first database when the user thaws the food next time. There is no need to enter the autonomous mode, which saves the user from inputting the type of food to be thawed and the target thawing time by themselves, and can quickly enter the thawing program, thereby improving the user experience.

[0079] Reference Figure 6 , Figure 6 is a flowchart of a method for entering an autonomous mode in response to a setting instruction provided by an embodiment of the present application, including steps S400 to S430. Specifically,

[0080] Step S400: Entering the autonomous mode in response to the setting instruction, receiving the type of food to be thawed input by the user and the mass of the food to be thawed determined by the weight sensor;

[0081] Step S410: matching the type of food to be thawed input by the user and the mass of the food to be thawed determined by the weight sensor in a first database, wherein the first database stores a correspondence between food type, food mass, and thawing time range;

[0082] Step S420: When a corresponding relationship is matched, a prompt message indicating that a corresponding relationship exists is issued, and the autonomous mode is exited;

[0083] Step S430: When no corresponding relationship is matched, the user is prompted to input the target thawing time, and the type of food to be thawed, the target thawing time and the mass of the food to be thawed determined by the weight sensor input by the user are sent to the first database to add a corresponding relationship.

[0084] In some embodiments of the present application, when it is necessary to thaw the food, if the user is not sure whether there is a corresponding relationship between the food type-food quality-thawing time in the first database, the user can choose to enter the autonomous mode and input the type of food to be thawed by himself. In response to the setting instruction, the autonomous mode is entered, the type of food to be thawed input by the user and the quality of the food to be thawed determined by the weight sensor are received, and the first database is matched according to the type of food to be thawed input by the user and the quality of the food to be thawed determined by the weight sensor; when the corresponding relationship is matched, a prompt message indicating that a corresponding relationship exists is issued, and the autonomous mode is exited. The user does not need to add a new corresponding relationship to the first database, which can avoid repeatedly establishing a corresponding relationship, thereby reducing the redundancy of the first database; when the corresponding relationship cannot be matched, the user is prompted to enter the target thawing time, and the user can enter the target thawing time through the human-computer interaction area; the type of food to be thawed, the target thawing time and the quality of the food to be thawed determined by the weight sensor input by the user are sent to the first database to add a new corresponding relationship.

[0085] In autonomous mode, the types of food to be thawed input by the user are first matched in the first database to determine whether there is a corresponding relationship. If there is a corresponding relationship, the autonomous modeling is exited, and a reference thawing time range is automatically sent for the user to determine the thawing time based on the reference thawing time range. The target thawing time determined by the user is received and the air supply device and the electric field generating device are started to thaw the food to be thawed, which can avoid repeatedly establishing the same corresponding relationship and speed up the thawing process. If there is no corresponding relationship, the user is reminded to autonomously input the target thawing time to add a new corresponding relationship, enriching the corresponding relationship data in the first database and increasing the probability that the food to be thawed has a matching relationship in the first database.

[0086] It should be noted that the first database in the embodiment of the present application includes a local database of the thawing device, and may also be a manufacturer's cloud database. The embodiment of the present application does not limit the type of the first database.
