Description

Technical Field

[0001] This invention relates to the field of refrigerators, and in particular to a method for extracting components to be extracted inside a refrigerator, as well as a refrigerator itself. Background Technology

[0002] In daily life, people often extract the active ingredients from extractable substances. Currently, commonly used extraction methods include room-temperature mechanical disruption, freeze-thaw extraction, and supercritical fluid extraction. Room-temperature mechanical disruption involves rapid heating and high oxygen exposure, making it difficult to achieve cell-level disruption. Under high temperature and oxygen conditions, the active ingredients in the extract are more prone to deterioration. Supercritical fluid extraction requires large equipment, making this method unsuitable for home use.

[0003] The freeze-thaw method refers to the repeated freezing and thawing of the extract. During freezing, the liquid inside the cells of the extract forms ice crystals, which expand and puncture the cell walls. After thawing, the active ingredients of the extract are released from the cells through the broken cell walls. Traditional refrigerators have a cooling function but lack a thawing function. Thawing the extract at room temperature presents problems such as slow thawing speed, difficulty in controlling the melting point, and spoilage due to over-thawing. Summary of the Invention

[0013] Optionally, the refrigerator also includes a temperature sensor for detecting the temperature of the extract; the step of detecting whether the intracellular liquid of the cells to be extracted is frozen to the first state includes:

[0014] The temperature of the extract was obtained;

[0015] Start timing once the temperature of the extract reaches the minimum set temperature;

[0016] The temperature of the extract is maintained at the lowest set temperature for a first set time period to achieve the first state.

[0017] Optionally, the refrigerator includes an electric heating element for heating the extract; the step of controlling the heating of the intracellular liquid of the cells to be extracted to a second state to cause the extractable components to precipitate from the broken cells includes:

[0024] The temperature of the extract is maintained at the highest set temperature for a second set time period to reach the second state so that the components to be extracted are separated from the broken cells.

[0025] Optionally, the refrigerator also includes an ultrasonic transducer for radiating sound waves to the extract.

[0026] Simultaneously with activating the electric heating element, the ultrasonic transducer is activated.

[0027] Simultaneously with shutting down the electric heating element, the ultrasonic transducer should also be turned off.

[0028] Optionally, after the step of controlling the heating of the intracellular liquid of the cells to be extracted to a second state to cause the component to be extracted to precipitate from the broken cells, the method further includes:

[0029] The process involves repeatedly freezing the intracellular liquid of the cells to be extracted to a first state and heating the intracellular liquid of the cells to be extracted to a second state until the set extraction termination conditions are met.

[0040] This invention provides a method for extracting components from a refrigerator and a refrigerator in which the extract is to be extracted. The method includes acquiring extraction information for the extract; controlling the freezing of the intracellular liquid of the extract to a first state; and controlling the heating of the intracellular liquid to a second state to allow the extract to precipitate from the broken cells. When the intracellular liquid is frozen to the first state, ice crystals form, which cause the cells to expand and rupture, breaking the hydrophobic bonds in the cell walls. When the intracellular liquid is heated to the second state, the ice crystals melt, and the active ingredients of the extract precipitate from the ruptured cells. Alternatively, the extractant can enter the cells to extract the active ingredients, thus completing the extraction. Furthermore, because the refrigerator has a heating function, this solves the problem of slow melting of the extract. Because the refrigerator can precisely control the freezing and thawing states, this solves the problems of difficulty in controlling the melting endpoint and food spoilage.

[0041] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0042] The following sections will describe some specific embodiments of the invention in a detailed manner by way of example and not limitation, with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar parts or portions. Those skilled in the art should understand that these drawings are not necessarily drawn to scale.

[0047] Figure 1 This is a flowchart of a method for extracting components to be extracted in a refrigerator according to an embodiment of the present invention; Figure 2 This is another flowchart of a method for extracting components to be extracted in a refrigerator according to an embodiment of the present invention; Figure 3 This is a schematic diagram of a refrigerator according to an embodiment of the present invention; Figure 4 This is a block diagram of a refrigerator according to an embodiment of the present invention.

[0048] like Figure 3 As shown, this embodiment provides a refrigerator 10, which includes a housing 100 and a container 200. The container 200 is disposed inside the housing 100; the container 200 is used to hold the extraction liquid, and the extraction liquid is used to place the extract to be extracted. In this embodiment, the shape of the container 200 can be selected as needed. As a specific embodiment, such as... Figure 3 As shown, the container 200 is rectangular in shape. Obviously, this is merely an example and not the only one; for example, the container 200 can be spherical, square, or other irregular shapes. In this embodiment, the size of the container 200 can be selected as needed, as long as the container 200 can be accommodated within the housing 100. As a specific embodiment, such as... Figure 3As shown, the volume of container 200 is much smaller than that of housing 100. Clearly, this is merely an example and not the only one. Container 200 is placed inside housing 100, causing the extract and the extract to be extracted within container 200 to freeze in refrigerator 10, resulting in the formation of ice crystals in the cells of the extract. These ice crystals cause the cells to swell and rupture, simultaneously breaking the hydrophobic bonds in the cell walls. This allows the extract to enter the cells and extract the active ingredients, or the active ingredients from the cells to flow into the extract, thus completing the extraction process.

[0049] Optionally, the container 200 is provided with a damper 210, through which cold air enters the container 200 to cool the extract and the extract to be extracted within the container 200. In this embodiment, the location of the damper 210 can be set as needed; for example, the damper 210 can be located on the front, top, left, right, or rear side of the container 200. As a specific embodiment, the damper 210 is located on the rear side of the container 200, close to the air duct of the refrigerator 10, which facilitates the introduction of cold air from the air duct into the container 200. The specific method by which the damper 210 opens the container 200 is not limited, as long as the opening degree of the damper 210 can be controlled. For example, the damper 210 can slide or rotate relative to the container 200 to open it. The damper 210 allows the container 200 to be frozen independently, which means that the temperature inside the container 200 is no longer controlled by the temperature inside the refrigerator 10, making the temperature inside the container 200 easier to control.

[0050] Optionally, the refrigerator 10 also includes a temperature sensor 300, which is used to detect the temperature of the extract. The temperature sensor 300 is used to detect whether the liquid inside the cells of the extract is frozen to a first state or heated to a second state. In this embodiment, the first state refers to the persistent state after the liquid inside the cells has formed ice crystals, and the second state refers to the state where the ice crystals have completely melted. Therefore, the detection method of the temperature sensor 300 is relatively simple and intuitive, and the temperature sensor 300 can accurately control the freezing and thawing states, solving the problems of difficult control of the thawing endpoint and food spoilage.

[0051] Optionally, the refrigerator 10 includes an electric heating element for heating the extract. The type of electric heating element is not limited; for example, it can be a resistance heater or an infrared heater. Optionally, the electric heating element includes a heating element 410; the heating element 410 is disposed within the extract and is used to heat the extract. Figure 3 As shown, the heating element 410 is evenly distributed at the bottom of the container 200 and located within the extract liquid. This ensures uniform heating of the extract liquid, high heat transfer efficiency of the heating element 410, and avoids affecting the original cooling effect of the refrigerator 10. The refrigerator 10 has a heating function, which solves the problem of slow melting of the extract.

[0052] Optionally, the refrigerator 10 also includes an ultrasonic transducer 500, which radiates sound waves to the extractant. The ultrasonic transducer 500 mainly comprises an ultrasonic transducer configured to radiate sound waves to the extractant. The ultrasonic transducer is used to rapidly introduce the extractant into the extractant, allowing it to quickly enter the cells for extraction; alternatively, the ultrasonic transducer is used to rapidly extract intracellular fluid from the cells for extraction. Furthermore, the ultrasonic transducer increases the temperature of the extractant, accelerating the transition of intracellular fluid from a first state to a second state, and speeding up the freezing and thawing of intracellular fluid, preventing deterioration of the extractant. Furthermore, the ultrasonic transducer removes oxygen from the extractant and neutralizes oxygen in the extractant, allowing the extractant to extract the active ingredients under low-oxygen conditions, preventing a decrease in the activity of the active ingredients in the extract.

[0053] like Figure 4 As shown, the refrigerator 10 in this embodiment is further provided with a controller 600. The controller 600 can be the main control device of the refrigerator 10, and may include a processor 610 and a memory 620. The memory 620 stores a machine-executable program 621. When the machine-executable program 621 is executed by the processor 610, it implements any of the methods for extracting the component to be extracted within the refrigerator 10 according to this embodiment. The processor 610 can be a single-core processor, a multi-core processor, a computing cluster, or any number of other configurations. The memory 620 may include random access memory (RAM), read-only memory, flash memory, or any other suitable storage system.

[0054] The machine-executable program 621 may be assembly instructions, instruction set architecture (ISA) instructions, machine instructions, machine-dependent instructions, microcode, firmware instructions, state setting data, or source code or object code written in any combination of one or more programming languages. In some embodiments, electronic circuitry, such as programmable logic circuitry, field-programmable gate arrays (FPGAs), or programmable logic arrays (PLAs), can be customized by utilizing state information from computer-readable program instructions to execute the machine-executable program 621, thereby implementing various aspects of the present invention.

[0055] like Figure 1 As shown, this embodiment provides a method for extracting a component to be extracted within a refrigerator 10. The refrigerator 10 includes a casing 100 and a container 200; the container 200 is disposed within the casing 100; the container 200 is used to hold an extraction solution, and the extract to be extracted is placed within the extraction solution. The method for extracting the component to be extracted includes:

[0056] S702: Obtain extraction information for the extract to be extracted;

[0057] The type of extract to be extracted is not limited; for example, it can be food or medicinal materials. The type of extraction information is also not limited; for example, it can be startup information, startup information combined with information about the extract to be extracted, etc. The information about the extract to be extracted includes its type and the criteria for ending the extraction process. Obtaining this information enables the refrigerator 10 to initiate the extraction process and to activate the corresponding extraction parameters based on the extraction information.

[0058] As a specific embodiment, obtaining the extraction information of the extract to be extracted includes obtaining the power-on signal and the type of the extract to be extracted, and obtaining extraction parameters that match the type of the extract to be extracted. The extraction parameters include one or more of the following: the opening degree of the damper 210, the minimum set temperature, the first set time period, the maximum set temperature, the second set time period, the power of the ultrasonic transducer 500, the frequency of the ultrasonic transducer 500, and the extraction termination condition.

[0059] The specific method for obtaining the power-on signal can be selected as needed, such as sending the power-on signal via a button on the refrigerator 10 or a mobile phone software. The opening and closing degree of the damper 210 is controlled to control the cooling rate of the extract. In this embodiment, the minimum set temperature can be selected according to the type of extract to be extracted. As a specific embodiment, the minimum set temperature is -15℃ to -20℃. In this embodiment, the maximum set temperature can be selected according to the type of extract to be extracted. As a specific embodiment, the maximum set temperature is 35℃ to 40℃. The first set time period is related to the crystallization rate of the intracellular fluid. If the crystallization rate of the intracellular fluid is slow, the first set time period is longer; if the crystallization rate of the intracellular fluid is fast, the first set time period is shorter. The second set time period is related to the melting rate of the intracellular fluid. If the melting rate of the intracellular fluid is fast, the second set time period is shorter; if the melting rate of the intracellular fluid is slow, the second set time period is longer.

[0060] S704: Control the freezing of the intracellular liquid in the cells to be extracted to the first state;

[0061] The specific freezing method for controlling the intracellular liquid of the cells to be extracted to freeze to the first state is not limited. For example, the container 200 can be naturally cooled by the refrigerator 10, or cold air can be introduced into the container 200 to cool it separately. In this embodiment, the first state refers to the state after the intracellular liquid forms ice crystals. When ice crystals form in the intracellular liquid, the cells rupture due to the expansion of the ice crystals. After the cells rupture, the active ingredients to be extracted are released from the cells. At the same time, the hydrophobic bonds of the cell wall break, which facilitates the entry of the extractant into the cells to extract the active ingredients, or the active ingredients of the cells may flow out of the cells to complete the extraction. The cold air of the refrigerator 10 freezes the intracellular liquid to the first state, which is simple in structure and easy to control.

[0062] In some other embodiments, the step of controlling the freezing of the intracellular liquid of the extract to a first state includes controlling the opening of the damper 210 of the container 200 to provide cold air to the container 200. In this embodiment, the opening position of the damper 210 can be set as needed. For example, the damper 210 can be opened on the front, top, left, right, or rear side of the container 200, provided that the position of the damper 210 allows cold air to enter the container 200 to cool the extract. In this embodiment, the source of the cold air is not specifically limited. For example, the cold air can come from a compartment inside the refrigerator 10 or from the air duct of the refrigerator 10. As a specific embodiment, such as... Figure 3 As shown, the damper 210 is located at the rear of the container 200, which makes it close to the air duct of the refrigerator 10, facilitating communication between the container 200 and the air duct of the refrigerator 10, allowing cold air from the air duct to enter the container 200. In this embodiment, the specific method by which the damper 210 opens the container 200 is not limited; for example, the damper 210 can slide or rotate relative to the container 200 to open it. The damper 210 allows the container 200 to be frozen independently, so that the temperature inside the container 200 is no longer controlled by the temperature inside the refrigerator 10, making the temperature inside the container 200 easier to control. The freezing rate of the extract in the container 200 can be controlled by controlling the opening and closing degree of the damper 210.

[0063] The step of controlling the freezing of the intracellular fluid of the extract to a first state also includes detecting whether the intracellular fluid of the extract has been frozen to the first state. As described above, the first state refers to the state in which the intracellular fluid is frozen to ice crystals. The specific detection method can be selected as needed, such as detecting the freezing time of the extract or detecting the freezing temperature of the extract, to ensure that the intracellular fluid is completely frozen to a freezing state.

[0064] The step of controlling the freezing of the intracellular liquid of the extract to the first state also includes closing the damper 210 after the intracellular liquid of the extract to the first state has been frozen. After the damper 210 is closed, this can prevent cold air from entering the container 200 further through the damper 210, and also prevent hot air from drifting into the refrigerator 10 through the damper 210 when heating the extract, thus affecting the cooling of the refrigerator 10.

[0065] In some other embodiments, the step of detecting whether the intracellular fluid of the extract has frozen to a first state includes obtaining the temperature of the extract. If the temperature of the extract reaches a minimum set temperature, timing begins. The temperature of the extract is maintained at the minimum set temperature for a first set time period to reach the first state. The minimum set temperature and the first set time period can be set according to the type of extract. Maintaining the minimum set temperature at the first set time period allows the intracellular fluid to crystallize sufficiently.

[0066] S706: Control the heating of the liquid inside the cells to be extracted to a second state so that the components to be extracted are separated from the broken cells.

[0067] The specific heating method is not limited; for example, it can be electric heating or heating with self-heating materials. If electric heating is used, an electrical signal can be sent to control the start of heating, and after heating to the second state, an electrical signal can be sent to control the stop of heating. If heating with self-heating materials is used, an electrical signal can be sent to control the delivery of an equivalent amount of self-heating material to start heating to the second state. The second state refers to the state where the ice crystals inside the cells are completely melted. Once the ice crystals are completely melted, the melted liquid precipitates out of the cells through the broken cell walls, completing the extraction.

[0068] In some other embodiments, the step of controlling the intracellular liquid of the cells to be extracted to be heated to a second state so that the extractable component is separated from the broken cells includes: turning on the electric heating element; detecting whether the intracellular liquid of the cells to be extracted has been heated to the second state; and turning off the electric heating element when the intracellular liquid of the cells to be extracted has been heated to the second state.

[0069] The type of electric heating element is not limited; for example, it can be resistance heating or infrared heating. Optionally, the electric heating element includes a heating element 410, and the activating electric heating element includes an activating heating element. Figure 3 As shown, the heating element 410 is evenly distributed at the bottom of the container 200 and located within the extract, which ensures uniform heating of the extract, high heat transfer efficiency of the heating element 410, and avoids affecting the original cooling effect of the refrigerator 10. Detecting whether the liquid inside the cells is heated to the second state ensures that the ice crystals inside the cells completely melt.

[0070] In some other embodiments, the step of detecting whether the intracellular fluid of the extractant has been heated to the second state includes: acquiring the temperature of the extractant; starting a timer if the temperature of the extractant reaches a maximum set temperature; and maintaining the temperature of the extractant at the maximum set temperature for a second set time period to reach the second state, thereby allowing the extractant components to precipitate from the broken cells. The maximum set temperature and the second set time period can be set according to the type of extractant; the maximum set temperature is used to prevent the extractant components from becoming ineffective, and the second set time period is used to ensure that the ice crystals inside the cells completely melt.

[0071] In some other embodiments, the ultrasonic transducer 500 is activated simultaneously with the step of activating the electric heating element; and the ultrasonic transducer 500 is deactivated simultaneously with the step of deactivating the electric heating element. The ultrasonic transducer 500 mainly includes an ultrasonic transducer configured to radiate sound waves to the extractant. The ultrasonic transducer is used to rapidly introduce the extractant into the extractant to be extracted, enabling the extractant to quickly enter the cells and complete the extraction; alternatively, the ultrasonic transducer is used to rapidly extract intracellular fluid from the cells to complete the extraction. Furthermore, ultrasound can increase the temperature of the extractant, increase the speed at which intracellular fluid transitions from a first state to a second state, accelerate the freezing and thawing of intracellular fluid, and prevent the extractant from deteriorating. Furthermore, ultrasound can remove oxygen from the extractant and neutralize oxygen in the extractant, allowing the extractant to extract the active ingredients in the extractant under low-oxygen conditions, preventing a decrease in the activity of the active ingredients in the extractant.

[0072] In some other embodiments, after the step of controlling the heating of the intracellular liquid of the cells to be extracted to a second state to cause the extractable components to precipitate from the broken cells, the method further includes: cyclically performing the step of controlling the freezing of the intracellular liquid of the cells to be extracted to a first state; and controlling the heating of the intracellular liquid of the cells to be extracted to a second state, until a set extraction termination condition is met. As described above, freezing the intracellular liquid to the first state forms ice crystals, which cause the cells to expand and rupture, breaking the hydrophobic bonds in the cell walls. This facilitates the entry of the extract into the cells. Cyclicly performing the above steps causes the cells to further expand and rupture, further disrupting the hydrophobic bonds, thereby fully extracting the effective components of the extract.

[0073] Figure 2 This is another flowchart of a method for extracting a component to be extracted within a refrigerator 10 according to an embodiment of the present invention, as follows: Figure 2 As shown, this embodiment can also be implemented according to the following steps.

[0074] S802: Obtain the power-on signal and the type of extract to be extracted;

[0075] S804: Obtain extraction parameters that match the type of extract to be extracted;

[0076] S806: Control the opening of the damper 210 of container 200 to provide cold air to container 200;

[0077] S808: Temperature of the extract;

[0078] S810: Start timing if the temperature of the extract reaches the minimum set temperature;

[0079] S812: Maintain the temperature of the extract at the lowest set temperature for a first set time period to achieve the first state;

[0080] S814: After freezing the cell sap to be extracted to the first state, close the damper 210;

[0081] S816: Turn on the heating element and ultrasonic transducer 500;

[0082] S818: Temperature of the extract;

[0083] S820: Start timing if the temperature of the extract reaches the maximum set temperature;

[0084] S822: Maintain the temperature of the extract at the highest set temperature for a second set time period to reach the second state so that the components to be extracted are released from the broken cells;

[0085] S824: When the cell fluid to be extracted is heated to the second state, turn off the electric heating element; turn off the ultrasonic transducer 500.

[0086] According to a second aspect of the present invention, a refrigerator 10 is also provided, comprising a housing 100, a container 200, and a controller 600. The container 200 is disposed within the housing 100 and is used to hold an extraction liquid, the extraction liquid containing the extract to be extracted. The controller 600 includes a memory 620 and a processor 610, wherein the memory 620 stores a machine-executable program 621, which, when executed by the processor 610, implements the method for extracting the component to be extracted within the refrigerator 10 as described above.
