Memory 420 may be, but is not limited to, any medium capable of carrying or storing desired program code in the form of instructions or data structures and accessible by a computer. The memory 420 may also be a combination of various memories. Since the machine executable program 421 implements each process of the following method embodiments when executed by the processor 410 and can achieve the same technical effect, to avoid duplication, the details will not be described again here.

Figure 2 is an internal structural diagram of the refrigerator 10 according to one embodiment of the present invention. The refrigerator 10 of this embodiment may further include a box 110 .

One or more storage spaces 112 are formed inside the box 110 for storing items, such as food ingredients.

The refrigeration system 200 may be a conventional compression refrigeration system, which may generally include a compressor, a condenser, a throttling device, and an evaporator, for example. The refrigeration system 200 is used to form a refrigeration airflow during cooling, and the refrigeration airflow is used to provide the storage space 112 to reduce the temperature of the storage space 112 . When the refrigeration system 200 is in operation, the refrigeration system 200 performs refrigeration. When the refrigerant flows through the evaporator, it absorbs heat and evaporates. The air flowing through the evaporator forms a refrigeration airflow. Of course, the refrigeration system 200 can also be other refrigeration systems used to generate cold energy. The refrigerator 10 may be an air-cooled refrigerator, but is not limited to this.

The oxygen treatment device 300 can be selectively connected with the air flow of any storage space 112, for example, can be disposed inside the storage space 112, so as to treat the oxygen in the storage space 112, for example, increase or decrease the oxygen content of the storage space 112. Oxygen content. Of course, the air flow communication method between the oxygen treatment device 300 and the storage space 112 can also be changed to through pipelines or air ducts. Indirect connection. When the oxygen treatment device 300 is in airflow communication with the storage space 112, the oxygen treatment device 300 can consume oxygen in the storage space 112 or provide oxygen to the storage space 112 when processing oxygen, and can also provide heat generated when processing oxygen to Storage space 112. The oxygen treatment device 300 generates heat when processing oxygen, and the air flowing through the oxygen treatment device 300 forms a heating air flow.

Figure 3 is a schematic structural diagram of the oxygen treatment device 300 of the refrigerator 10 according to one embodiment of the present invention. FIG. 4 is a schematic exploded view of the oxygen treatment device 300 of the refrigerator 10 shown in FIG. 3 . The oxygen treatment device 300 may be an electrolysis device that consumes or generates oxygen by performing an electrochemical reaction. For example, the oxygen treatment device 300 may generally include a housing 310, a cathode portion 322, and an anode portion 321. Among them, the cathode part 322 and the anode part 321 are respectively plate-shaped electrodes. The casing 310 is provided with an assembly opening, and the cathode portion 322 is disposed at the assembly opening to jointly define an electrolytic chamber 312 for containing electrolyte together with the casing 310 . The anode part 321 and the cathode part 322 are arranged in the electrolytic chamber 312 and are spaced apart from each other.

For example, the cathode part 322 can be used to be electrically connected to the negative electrode of the power supply, and the oxygen in the air can undergo a reduction reaction at the cathode part 322, that is: O2+2H2O+4e-→4OH-. The anode part 321 can be used to be electrically connected to the positive electrode of the power supply. The OH- generated by the cathode part 322 can undergo an oxidation reaction at the anode part 321 and generate oxygen, that is: 4OH-→O2+2H2O+4e-. While the anode part 321 uses OH- to cause an electrochemical reaction, it also provides reactants, such as electrons e-, to the cathode part 322.

Of course, the structure of the oxygen treatment device 300 and the means for treating oxygen are not limited to this. After understanding the embodiments of the present disclosure, those skilled in the art should easily extend the technical solutions of these embodiments to other types of oxygen treatment devices (for example, based on the oxygen-rich membrane principle or based on the adsorption-desorption principle, etc.) Refrigerator 10 (oxygen regulating device for oxygen content).

Figure 5 is a schematic diagram of a control method of the refrigerator 10 according to an embodiment of the present invention. The control method generally includes the following steps:

Step S502: Determine the target temperature of the storage space 112 of the refrigerator 10. Storage space 112 The target temperature refers to the temperature to which the storage space 112 will be adjusted, which may be a temperature point or a temperature range. For example, the target temperature of the storage space 112 may be any temperature point or temperature interval within the temperature range of 1 to 9°C, 10 to 15°C, or lower than 0°C.

The storage space 112 in this embodiment may refer to the storage space 112 that is in airflow communication with the oxygen treatment device 300 and can receive the refrigeration airflow generated by the refrigeration system 200 . And the number of storage spaces 112 in this embodiment may be one or more. In order to describe the embodiment more clearly, the storage space 112 mentioned in the following embodiments may specifically refer to a certain storage space 112 .

Step S504, determine the heat source of the storage space 112 according to the target temperature. The heat source is selected from the refrigeration air flow formed by the refrigeration system 200 of the refrigerator 10 when cooling, and the heating air flow formed by the oxygen treatment device 300 of the refrigerator 10 when processing oxygen. . Determining the heat source of the storage space 112 according to the target temperature means configuring the heat source of the storage space 112 according to the target temperature.

For example, when the target temperature of the storage space 112 is low, the heat source may be a refrigeration airflow, and the refrigeration airflow may lower the temperature of the storage space 112 so that it reaches or approaches the target temperature. When the target temperature of the storage space 112 is relatively high, the heat source may be the above-mentioned heating air flow, and the heating air flow may increase the temperature of the storage space 112 so that it reaches or approaches the target temperature.

Step S506: Provide a heat source to the storage space 112 so that the storage space 112 reaches or approaches the target temperature. Providing a heat source to the storage space 112 means providing cooling air flow or heating air flow to the storage space 112 to adjust the temperature of the storage space 112 . For example, the temperature of the storage space 112 being close to the target temperature means that the difference between the temperature of the storage space 112 and the target temperature is less than 10% of the target temperature.

Using the above method, by determining the target temperature of the storage space 112 and determining the heat source of the storage space 112 according to the target temperature, the heat source can be selected from the refrigeration air flow formed by the refrigeration system 200 during cooling and the oxygen treatment device 300 when processing oxygen. The formed heating air flow can utilize the heat generated by the oxygen treatment device 300 to adjust the temperature of the storage space 112 , so that the heat generated by the oxygen treatment device 300 no longer acts as a "burden" on the refrigerator 10 . Based on the solution of this embodiment, the energy efficiency of the refrigerator 10 can be improved by rationally utilizing the heat generated by the oxygen treatment device 300, which is a very clever idea.

It is worth emphasizing that when faced with the situation that the oxygen treatment device 300 generates heat due to processing oxygen and causes temperature fluctuations in the storage space 112, those skilled in the art can easily think of using refrigeration air flow to balance the heat generated by the oxygen treatment device 300. The temperature rise brought about. The solution of this embodiment can turn waste into treasure by utilizing the heat generated by the oxygen treatment device 300. This breaks through the ideological shackles of the existing technology and provides a new idea for solving the heat generation problem of the oxygen treatment device 300. , and at the same time, it also solves multiple technical problems such as the difficulty in providing a suitable storage environment for low-temperature-sensitive food materials due to the single temperature setting of the cold storage compartment of the refrigerator 10, and the high energy consumption of the refrigerator 10. It serves multiple purposes.

As a low-temperature preservation device, the refrigerator 10 can provide a low-temperature preservation environment for the storage of food ingredients. In the existing refrigerator 10, the temperature of the cold storage compartment is generally set to 1°C to 9°C, and this temperature range is suitable for storing most food ingredients. However, some special ingredients, such as bananas, pineapples, mangos, papayas, etc., are extremely sensitive to low temperatures. If stored in a low-temperature environment below 10°C, cold damage may easily occur, causing the ingredients to lose nutrients or even become "frozen". or deteriorate. The inventor realized that a single temperature setting scheme of the cold storage compartment of the refrigerator 10 may not meet the storage needs of some special ingredients.

According to the solution of this embodiment, when the heating air flow generated by the oxygen treatment device 300 when processing oxygen is provided to the storage space 112, the heat generated by the oxygen treatment device 300 can be used to increase the temperature of the storage space 112, making the storage The temperature of the space 112 is higher than the conventional refrigeration temperature, making the storage space 112 suitable for storing certain low-temperature-sensitive ingredients. The refrigerator 10 can provide a suitable storage environment for these low-temperature-sensitive ingredients, which is equivalent to expanding the storage capacity of the refrigerator 10 The temperature zone is beneficial to improving the freshness preservation performance of the refrigerator 10 .

Since the oxygen treatment device 300 can be used to process the oxygen in the refrigerator 10 and also can be used to adjust the temperature of the storage space 112 in the refrigerator 10, only by arranging the oxygen treatment device 300 in the refrigerator 10, the oxygen treatment device 300 can be used. The refrigerator 10 obtains the function of controlled atmosphere preservation and temperature zone expansion without the need to install other adjustment devices. Therefore, the solution based on this embodiment is conducive to simplifying the structure of the refrigerator 10 and realizing the function reuse of the oxygen treatment device 300 .

Since the storage space 112 can selectively receive the energy generated by the refrigeration system 200 during cooling, The refrigeration air flow and the heating air flow generated by the oxygen treatment device 300 when processing oxygen, therefore, the temperature of the storage space 112 can be adjusted in a targeted manner, so that the storage space 112 can be adjusted according to the actual storage needs of the user. Flexibly changing the storage temperature can improve the utilization of the storage space 112 and prevent the storage space 112 from being idle and wasting space due to the user temporarily not storing certain ingredients.

In some optional embodiments, when it is determined that the heat source of the storage space 112 is a heating air flow, before providing the heat source to the storage space 112, the control method further includes: determining the target oxygen amount of the storage space 112, The working mode of the oxygen treatment device 300 is determined according to the target oxygen amount, and the oxygen treatment device 300 is configured according to the working mode, so that the oxygen treatment device 300 operates according to the working mode after being started. The target oxygen amount of the storage space 112 refers to the target oxygen environment to which the storage space 112 will be adjusted. For example, oxygen concentration can be used to characterize the amount of oxygen. The target oxygen amount of the storage space 112 may refer to the oxygen concentration to which the storage space 112 will be adjusted. Of course, the representation method of the target oxygen amount is not limited to this. The working mode of the oxygen treatment device 300 refers to the working mode in which the oxygen treatment device 300 will operate.

The working mode of the oxygen treatment device 300 is set corresponding to the target oxygen amount. After determining the working mode of the oxygen treatment device 300 according to the target oxygen amount, when the oxygen treatment device 300 operates in the working mode, the actual oxygen amount in the storage space 112 can be made to reach or be close to the target oxygen amount. For example, the fact that the actual oxygen amount in the storage space 112 is close to the target oxygen amount means that the difference between the oxygen amount in the storage space 112 and the target oxygen amount is less than 10% of the target oxygen amount.

By configuring the oxygen treatment device 300 according to the working mode, the oxygen treatment device 300 can adjust the oxygen content of the storage space 112 according to the target oxygen amount on the one hand, and adjust the temperature of the storage space 112 according to the target temperature on the other hand, thereby The oxygen treatment device 300 is allowed to take into account the temperature adjustment needs and oxygen adjustment needs of the storage space 112 .

In some optional embodiments, in the step of determining the working mode of the oxygen treatment device 300 according to the target oxygen amount, multiple working modes of the oxygen treatment device 300 may be preset. For example, the working modes of the oxygen treatment device 300 may include an oxygen removal heating mode and a separate heating mode, wherein the oxygen treatment device 300 is used to consume the storage space 112 in the oxygen removal heating mode. oxygen and generate heat, the oxygen treatment device 300 is used in the separate heating mode to only generate heat without processing oxygen. Determining the working mode of the oxygen treatment device 300 based on the target oxygen amount means determining in which working mode the oxygen treatment device 300 will start operating based on the target oxygen amount.

For example, when the target oxygen amount is small, the operating mode of the oxygen treatment device 300 determined based on the target oxygen amount may be the oxygen removal heating mode. When the target oxygen amount is substantially consistent with the oxygen content in the air, the working mode of the oxygen treatment device 300 determined according to the target oxygen amount may be a separate heating mode. In some optional embodiments, when the target oxygen amount is large, the working mode of the oxygen treatment device 300 determined according to the target oxygen amount may be the following oxygen-generating heating mode.

Using the above method, the working mode of the oxygen treatment device 300 can be flexibly selected based on the target oxygen amount of the storage space 112, which can improve the air-conditioned freshness preservation performance of the refrigerator 10 and allow the oxygen treatment device 300 to appropriately adjust the storage space while generating heat. The amount of oxygen is 112.

In some optional embodiments, the step of determining the working mode of the oxygen treatment device 300 according to the target oxygen amount includes: determining whether the target oxygen amount is lower than the first preset value, and if so, determining the working mode of the oxygen treatment device 300 It is deoxidation heating mode.

In the oxygen removal and heating mode, the cathode portion 322 of the oxygen treatment device 300 is in airflow communication with the storage space 112 and is used to consume the oxygen content of the storage space 112 through an electrochemical reaction.

The housing 310 of the oxygen treatment device 300 may be provided with an exhaust port 314 for exhausting oxygen generated by the anode part 321. The refrigerator 10 may further include a separation compartment 500 and an air guide assembly 600 . The air guide assembly 600 has an air inlet end, a first air outlet end and a second air outlet end, wherein the air inlet end is used to communicate with the exhaust port 314, and the first air outlet end is connected with another storage space 112 that needs oxygenation, It is used to guide the oxygen flowing out of the exhaust port 314 to the storage space 112 . The second air outlet is used to communicate with the external environment of the refrigerator 10 and to guide the oxygen flowing out of the exhaust port 314 to the external environment. The air guide assembly 600 includes an air guide switch valve 610, a first air outlet conduit 620 and a second air outlet conduit 630. The air guide switch valve 610 has an air guide air inlet interface, a first air guide valve port and a second air guide valve port, wherein the air guide air inlet interface is used to connect to the exhaust port 314 and serve as For the air intake end. The first air outlet conduit 620 and the second air outlet conduit 630 are respectively connected with the first air guide valve port and the second air guide valve port, wherein the first air outlet conduit 620 extends from the first air guide valve port to the storage tank that needs oxygenation. The second air outlet duct 630 extends from the second air guide valve port to the external environment of the refrigerator 10 and its end serves as the second air outlet end.

The separation chamber 500 has an air inlet and an air outlet, wherein the air inlet is connected with the exhaust port 314, and an arc-shaped airflow channel is formed inside the separation chamber 500, which is used to make the oxygen flowing through it flow along the curved surface, thereby allowing the oxygen to flow. Separation of carried liquids. The air outlet is connected with the air guide and air inlet interface, and is used to discharge the oxygen after separating the liquid to the air guide and air inlet interface. In the deoxygenation and heating mode, the oxygen generated by the anode part 321 of the oxygen treatment device 300 can flow sequentially. Through the separation bin 500 and the air guide assembly 600, it is transported to the storage space 112 that needs oxygenation or the external environment of the refrigerator 10.

In some optional embodiments, when the target oxygen amount of the storage space 112 is not lower than the first preset amount, the working mode of the oxygen treatment device 300 may be determined as the individual heating mode. In the separate heating mode, the oxygen treatment device 300 performs the heat generation function without affecting the oxygen content of the storage space 112 .

In the separate heating mode, the anode part 321 of the oxygen treatment device 300 can be electrically connected to the negative pole of the power supply, and the cathode part 322 can be electrically connected to the positive pole of the power supply, so that the anode part 321 and the cathode part 322 can only generate heat without conducting electrical power. chemical reaction. Of course, the manner in which the oxygen treatment device 300 only generates heat without performing an electrochemical reaction is not limited to the above example.

For example, the oxygen treatment device 300 may be disposed in the storage space 112, and the side of the cathode portion 322 facing the storage space 112 may be in contact with oxygen in the air. When it is determined that the operating mode of the oxygen treatment device 300 is the deoxygenation heating mode, the cathode part 322 is configured to be electrically connected to the negative electrode of the power supply, and the anode part 321 is configured to be electrically connected to the positive pole of the power supply. At this time, the oxygen treatment device 300 is started. After that, it can work in deoxidation heating mode. When it is determined that the operating mode of the oxygen treatment device 300 is the single heating mode, the cathode part 322 is configured to be electrically connected to the positive electrode of the power supply, and the anode part 321 is configured to be electrically connected to the negative pole of the power supply. At this time, the oxygen treatment device 300 After starting, it can work in separate heating mode.

In some optional embodiments, the working mode of the oxygen treatment device 300 also includes an oxygen-generating heating mode. In the oxygen-generating heating mode, the oxygen treatment device 300 is used to increase oxygen in the storage space 112 and generate heat. That is to say, the oxygen treatment device 300 can be preset with three working modes, namely, oxygen removal heating mode, separate heating mode and oxygen generation heating mode, and any working mode can be selectively determined as the expected working mode. model.

In the oxygen-generating heating mode, the exhaust port 314 of the oxygen treatment device 300 is in airflow communication with the storage space 112, and is used to transport the oxygen generated by the anode part 321 to the storage space 112, thereby increasing the oxygen content of the storage space 112. . In the oxygen-generating heating mode, the cathode portion 322 of the oxygen treatment device 300 disposed in the storage space 112 is not in airflow communication with the storage space 112 .

For example, the oxygen treatment device 300 may have multiple cathode parts 322 , one cathode part 322 may be disposed in the storage space 112 , and the other cathode parts 322 may be disposed outside the storage space 112 . In the oxygen-generating heating mode, the anode part 321 can form an electrode pair with any cathode part 322 arranged outside the storage space 112, and the electrode pair is connected to the electrolysis voltage to perform an electrochemical reaction.

In some embodiments, the housing 310 may be provided with multiple assembly openings, and one assembly opening is used to install one cathode part 322 . The storage space 112 may be provided with a communication port connected to the external environment. A part of the housing 310 of the oxygen treatment device 300 can be inserted into the communication port, so that one cathode portion 322 is disposed in the storage space 112 and the other cathode portion is opposite to the cathode portion 322 disposed in the storage space 112 . 322 is provided outside the storage space 112 .

In some optional embodiments, the step of determining the working mode of the oxygen treatment device 300 according to the target oxygen amount further includes: when the target oxygen amount is not lower than the first preset amount, determining whether the target oxygen amount is higher than the first preset amount. The second preset value is greater than the first preset value. If yes, it is determined that the working mode of the oxygen treatment device 300 is the oxygen-generating heating mode. If not, then the working mode of the oxygen treatment device 300 is determined. The mode is separate heating mode.
