[0035] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly, the present application will be further described in detail in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0036] The principles and structures of the present application will be described in detail in combination with the drawings and embodiments.

[0037] When the current mainstream air-cooled refrigerator is equipped with a deodorization and sterilization function, and most of them use natural negative ion adsorption and digestion deodorization, photocatalyst sterilization and deodorization, high-voltage discharge to generate ions and ozone sterilization and deodorization, etc. The operation rules are also controlled by relatively simple parameters such as temperature and time, and cannot achieve the self-adaptive effect of random response. Especially when multiple deodorization and sterilization devices are involved, there is no way to adjust the working state of each deodorization and sterilization device according to the actual state of the refrigerator freezer compartment to improve the deodorization and sterilization effect. In view of this, the present application proposes a deodorization function control method, which collects the CO2 content and the volume of stored food in the refrigerator compartment through a CO2 detector and an infrared sensor, and distinguishes and controls whether the refrigerator compartment is opened. Let the first sterilization and deodorization device and the second deodorization device work in order. It can control the working state of multiple deodorization and sterilization devices with different deodorization effects according to the volume change of the food and the CO2 content change of the refrigerator compartment to deodorize and sterilize, which is more in line with the actual working state of the refrigerator.

[0038] As shown in Figure 1 The present application proposes a deodorization function control method, which includes the following steps:

[0039] The profile and volume of the food material in the refrigeration chamber are sensed by an infrared sensor, and the CO2 content (or concentration) in the refrigeration chamber is detected in real time by a CO2 detector;

[0040] It is judged whether the refrigeration door of the refrigerator is opened or not;

[0041] If yes, the working state of the sterilization and deodorization device with different deodorization effects is controlled according to the volume change of the food material to perform sterilization and deodorization;

[0042] If no, the working state of the sterilization and deodorization device with different deodorization effects is controlled according to the CO2 content change in the refrigeration chamber to perform sterilization and deodorization. The working state of each deodorization device can be adjusted according to the actual situation of the refrigerator. That is, the weight change of the food material or the CO2 content change in the refrigeration chamber will change the working state of the primary sterilization and deodorization device and the secondary deodorization device, so that the deodorization effect of the refrigeration chamber matches the actual situation.

[0043] By recognizing the door opening and closing action and the volume change of the food material, it is recognized whether the food material is stored or taken out, and the order of sterilization and deodorization is determined according to the number of microorganisms entering the refrigeration chamber, and the working time of the primary sterilization and deodorization device is reasonably controlled according to the volume of the newly added food material. Under the condition that the refrigerator door is not opened, the threshold value is set by comparing the actual measurement of the CO2 content, so as to judge the degree of microorganism reproduction and decomposition of the food material, and to determine whether to open the primary sterilization and deodorization device, and to control the working time of the primary sterilization and deodorization device according to the volume of the stored food material, while considering the odor volatilization factor of the food material itself, and to open the secondary deodorization device at regular intervals to timely eliminate the odor inside the chamber. The self-adaptive ability of the sterilization and deodorization function of the refrigerator is improved, and the energy consumption of the appliance is reduced.

[0044] As shown in Figure 2 In specific embodiments, the present application provides two deodorization devices, specifically a primary sterilization and deodorization device and a secondary deodorization device. The sterilization effect of the primary sterilization and deodorization device is strong, and the deodorization effect of the secondary deodorization device is more direct and obvious. Because the odor in the refrigerator is caused by both bacterial reproduction and food spoilage, and the odor is caused by the mixing of the odor of the food material itself. The difference between them is that the primary sterilization and deodorization device has both sterilization and deodorization functions, which can suppress the odor caused by bacterial reproduction and food spoilage from the source, and the secondary deodorization device mainly directly decomposes odor substances to eliminate odor, and the deodorization effect is stronger.

[0045] It should be noted that a person skilled in the art can use more numbers of deodorization devices for sterilization and deodorization, as long as the working state of the sterilization and deodorization device with different deodorization effects is controlled according to the volume change of the food material or the working state of the sterilization and deodorization device with different deodorization effects is controlled according to the CO2 content change in the refrigeration chamber, which is within the protection scope of the present application.

[0046] In specific embodiments, the working state of the sterilization and deodorization device with different deodorization effects is controlled according to the volume change of the food material, and specifically includes:

[0047] determining whether the difference AV between the volume V2 of the food material after the opening of the refrigeration door and the volume V1 of the food material before the opening of the refrigeration door is greater than 0 (unit: L);

[0048] If yes, it indicates that the user puts new food material into the refrigerator, at this time, the first-stage sterilization and deodorization device and the second-stage deodorization device are controlled to be turned on, and the working time T1 of the first-stage sterilization and deodorization device and the working time T2 of the second-stage deodorization device are recorded respectively (the working time is the working time after the opening), the refrigeration compartment is forced to refrigerate (i.e., opened to the maximum power, the refrigeration speed is fast) and the refrigeration compartment temperature t1 is recorded.

[0049] If no, it indicates that the user does not put new food material into the refrigerator, which may be that the food material is not taken out or the food material is taken out, at this time, the first-stage sterilization and deodorization device is controlled to be turned on, and the working time T1 of the first-stage sterilization and deodorization device is recorded, when the working time T1 is greater than or equal to a preset time d (d can be 2h), the first-stage sterilization and deodorization device is controlled to stop working, and the working time T1 is cleared. That is, only a small amount of deodorization combined with primary sterilization can meet the needs.

[0050] Odorous substances will spread in the air with the flow of air, and the second-stage deodorization device mainly reacts with and decomposes the odorous substances in the air flowing through it. After the refrigeration compartment is opened to store new food material, new bacteria and odors will enter the refrigerator, and the first-stage sterilization and deodorization device and the second-stage deodorization device are turned on to achieve the cleaning effect of sterilization and deodorization as soon as possible. At this time, in order to improve the deodorization speed, the refrigeration compartment needs to be refrigerated (forced convection) to speed up the air flow speed, so that more odorous substances flow through the second-stage deodorization device and react with it. However, if the refrigeration compartment is refrigerated for a long time, the temperature will be too low to affect the quality of the food material, so the working time of the second-stage deodorization device is controlled based on the refrigeration compartment temperature.

[0051] After the above step of the difference AV being greater than 0 and the refrigeration compartment being forced to refrigerate (i.e., opened to the maximum power, the refrigeration speed is fast) and the refrigeration compartment temperature t1 being recorded, the specific judgment logic of the second-stage deodorization device is: determining whether the refrigeration compartment temperature t1 reaches the refrigeration compartment set temperature, and whether the working time T2 of the second-stage deodorization device is greater than or equal to a preset time e;

[0052] When the refrigeration compartment temperature t1 reaches the refrigeration compartment set temperature, and the working time T2 of the second-stage deodorization device is greater than or equal to the preset time e, the second-stage deodorization device stops working, the working time T2 is cleared, the refrigeration compartment is opened to normal refrigeration, and the non-working time T3 of the second-stage deodorization device is cleared and recorded again.

[0053] If no, the refrigeration chamber continues to open the forced refrigeration, the secondary odor-removing device is normally opened and the working time T2 is recorded.

[0054] After the above-mentioned step that the difference AV is greater than 0 and the refrigeration chamber opens the forced refrigeration (i.e. opens to the maximum power, the refrigeration speed) and records the refrigeration chamber temperature t1, the specific judgment logic of the primary sterilization and odor-removing device is: judging through the working time T1 of the primary sterilization and odor-removing device, specifically judging whether T1≥n+0.1*AV or T1≥f is established;

[0055] If yes, that is, when T1≥n+0.1*AV or T1≥f, wherein f and n are preset values (n can be specifically 2h, and f can be 8h), the primary odor-removing and sterilization device is controlled to stop working, and the working time T1 is cleared.

[0056] If no, the refrigeration chamber continues to open the forced refrigeration, and the primary sterilization and odor-removing device is normally opened and the working time T1 is recorded.

[0057] After the above-mentioned step that the primary odor-removing and sterilization device is controlled to stop working and the working time T1 is cleared, or the working time T2 is cleared, the refrigeration chamber opens the normal refrigeration, and the non-working time T3 of the secondary odor-removing device is cleared and re-recorded, the step of returning to sensing the outline and volume of the food material in the refrigeration chamber through the infrared sensor and detecting the CO2 content (or concentration) in the refrigeration chamber in real time through the CO2 detector is returned, and the above-mentioned process is re-judged whether the refrigerator refrigeration door is opened.

[0058] In a specific embodiment, the working state of the sterilization and odor-removing device with different odor-removing effects controlled according to the change of the CO2 content in the refrigeration chamber specifically includes the following steps:

[0059] Judging whether the change amount AC of the CO2 content C in the preset door-closing time (the preset door-closing time can be specifically 3h, that is, the chamber door is not opened within 3h) is greater than or equal to a preset content;

[0060] If yes, it means that the CO2 content is high, and there are more microorganisms, which need to be sterilized and odor-removed, and the primary sterilization and odor-removing device is opened, and the working time T1 of the primary sterilization and odor-removing device is recorded.

[0061] If no, judging whether the non-working time T3 of the secondary odor-removing device after the last opening and stopping is greater than or equal to a preset time g; if yes, controlling the secondary odor-removing device to open and record the working time T2, and the refrigeration chamber to open the forced refrigeration and record the refrigeration chamber temperature t1; if no, controlling the primary sterilization and odor-removing device and the secondary odor-removing device to not work.

[0062] After executing the above steps of turning on forced cooling in the refrigerator and recording the refrigerator temperature t1, when the refrigerator temperature t1 reaches the set temperature of the refrigerator, and the working time T2 of the secondary odor purification device is greater than or equal to the preset time e (e can be 0.25h), the secondary odor purification device is controlled to stop working, the working time T2 is reset, the refrigerator starts normal cooling, and the non-working time T3 of the secondary odor purification device is reset and starts recording, because the refrigerator will automatically produce some odor due to the respiration of the food.

[0063] After executing the steps of activating the primary sterilization and deodorization device and recording the primary sterilization and deodorization device operating time T1, if T1 ≥ m*V1+p*C (V1 is the volume of food stored in the refrigerator before the door is opened, and C is the measured CO2 content in the refrigerator), the primary sterilization and deodorization device is controlled to stop operating, and the primary sterilization and deodorization device operating time T1 is reset to zero. Both m and p are preset values. In a preferred embodiment, m can be 0.02 and p can be 0.01.

[0064] The above-mentioned control of the first-level sterilization and odor purification device to stop working, and the working time T1 of the first-level sterilization and odor purification device is reset to zero, or the first-level sterilization and odor purification device and the second-level odor purification device are both controlled not to work, or the second-level odor purification device is controlled to stop working, the working time T2 is reset to zero, the refrigerator compartment is turned on for normal refrigeration, and the non-working time T3 of the second-level odor purification device is reset to zero and starts recording, then returns to the step of sensing the outline and volume of the food in the refrigerator compartment through the infrared sensor, and detecting the CO2 content (or concentration) in the refrigerator compartment in real time through the CO2 detector, and re-determining whether the refrigerator door is open to cycle the above process.

[0065] like Figure 3 As shown, after the refrigerator is powered on, a pre-odor removal program is first executed to control the sterilization and odor removal devices with different odor removal effects to pre-odorize the refrigerator. After executing the pre-odor removal program, a step of determining whether the refrigerator door is open is executed.

[0066] Because users may not clean the refrigerator properly after a power outage, or may not clean it properly, food residue may remain. During this unused period, bacteria may grow and odors may develop. When the refrigerator is powered on again, two sterilization and deodorization devices pre-clean the refrigerator, reducing the workload of subsequent sterilization and deodorization, while also improving food safety.

[0067] The pre-deodorization process specifically includes:

[0068] The first sterilization and odor removal device is controlled to start, and the working time T1 of the first sterilization and odor removal device is recorded. When T1 is greater than the preset time a, the first sterilization and odor removal device is controlled to stop working, and the working time T1 is reset.

[0069] Control the secondary odor purification device to start, and record the working time T2 of the secondary sterilization and odor purification device. At the same time, turn on the forced cooling of the refrigerator and record the refrigerator temperature t1. When the refrigerator temperature t1 reaches the set temperature of the refrigerator, and the working time T2 is greater than the preset time b (b is the first working time of the secondary odor purification device after power-on, which can be 0.5h), control the secondary odor purification device to stop working, the working time T2 is reset, the refrigerator starts normal cooling, and the non-working time T3 of the secondary odor purification device is reset and starts recording.

[0070] The terms used above are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0071] The present invention also proposes a refrigerator, which specifically uses the above-mentioned odor removal control method to control multiple sterilization and odor removal devices installed in the refrigerator to sterilize and odor remove the refrigerator.

[0072] like Figure 4 As shown, the refrigerator specifically includes: an infrared sensor 1, a primary sterilization and deodorization device 2, a temperature sensor 3, a CO2 detector 4, and a secondary deodorization device 5. The infrared sensor 1 is set on the side wall of the refrigerator compartment, such as the upper side wall (i.e., the top surface of the refrigerator compartment), to sense the outline of the food and calculate the volume. The primary sterilization and deodorization device 2 is set in the refrigerator compartment and can be used for deodorization and sterilization. Its deodorization effect is weaker than that of the second deodorization device 5. The secondary deodorization device 5 is set at the channel opening of the return air duct 6 of the refrigerator compartment. The temperature sensor is used to detect the temperature of the refrigerator compartment, and the CO2 detector can detect the CO2 content in the refrigerator compartment in real time.

[0073] Infrared sensors are commonly used to detect contours and measure volume in existing technologies. That is, when food at room temperature is put in or food in the refrigerator is taken out, there will be a temperature difference. Infrared thermal imaging can be used to sense the contours of food and calculate the volume based on the different temperatures. Infrared cameras use the principle of infrared thermal imaging.

[0074] In addition, infrared light curtains are used to measure the volume of food. Most instruments for measuring the volume of items in the express logistics industry use this technology.

[0075] The present invention also proposes a computer storage medium for storing a computer program, which executes the above-mentioned odor-purifying function control method when running.

[0076] In one or more exemplary embodiments, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software as a computer program product, the functions may be stored on or transmitted via a computer-readable medium as one or more instructions or codes. Computer-readable media include both computer storage media and communication media, including any media that facilitates the transfer of a computer program from one location to another.

Any connection is also properly referred to as a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwaves, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwaves are included in the definition of medium. As used herein, disk and disc include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray disc, where disks typically reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above should also be included within the scope of computer-readable media.
