Description

Technical Field

[0001] The present application relates to the field of smart home technology, and in particular to a refrigerator control method, device, refrigerator, and computer-readable medium. Background Art

[0002] As a core appliance for household food storage, the healthiness of the refrigerator's internal environment and the comfort of its user experience are increasingly becoming a focus of user attention. While the ozone sterilization technology widely used in traditional refrigerators can effectively inhibit bacterial growth, the sterilization process inevitably produces residual ozone. This residual ozone not only has the potential to irritate the human respiratory mucosa, posing a health risk, but also releases a pungent odor when the door is opened, significantly affecting the user's sensory experience. Existing technologies, such as photocatalytic antibacterial and deodorizing devices and the addition of antimicrobial agents to the inner liner, only achieve contact sterilization and cannot address the problems of residual ozone and odor within the refrigerator's interior.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module" and "component" can be used interchangeably.

[0029] In order to solve the problems mentioned in the background technology, according to one aspect of the embodiments of the present application, an embodiment of a refrigerator control method is provided, such as Figure 1 As shown, the method may include the following steps:

[0030] Step S102, performing a sterilization and odor removal operation on the refrigerator;

[0031] Step S104: When the sterilization and odor removal operation is completed, an ozone elimination operation is performed to reduce the ozone concentration in the refrigerator.

[0032] Through steps S102 to S104, the present application performs an ozone elimination operation after the refrigerator completes sterilization and deodorization, effectively eliminating residual ozone, and solving the technical problem that residual ozone after sterilization in the refrigerator can easily lead to health hazards and odors.

[0033] In an embodiment of the present application, the conditions for triggering the refrigerator sterilization and odor removal operation may include but are not limited to bacteria-oriented triggering, odor-oriented triggering, detection of food being placed in, and reaching a preset inspection cycle (such as every 12 hours).

[0034] In an optional embodiment, taking bacteria-oriented triggering and odor-oriented triggering as an example, the sterilization and odor removal operation of the refrigerator includes:

[0035] detecting the concentration of bacteria and / or odorous gases in the refrigerator;

[0036] When the bacteria concentration reaches a first bacteria concentration threshold, the sterilization module is activated to perform sterilization, and when the bacteria concentration is less than or equal to a second bacteria concentration threshold, the sterilization module is deactivated, wherein the second bacteria concentration threshold is less than the first bacteria concentration threshold;

[0037] When the odor gas concentration reaches a first odor gas concentration threshold, the odor purification module is turned on for odor purification, and the odor purification module is turned off until the odor gas concentration is less than or equal to a second odor gas concentration threshold, wherein the second odor gas concentration threshold is less than the first odor gas concentration threshold.

[0038] In the embodiment of the present application, the sterilization and odor removal module may include a sterilization module and an odor removal module. The sterilization module may include an ion generator, a fan, etc., and the odor removal module includes a negative ion generator.

[0039] In the embodiment of the present application, a bacteria concentration sensor can be used to monitor the bacterial concentration in real time, with the unit being CFU / m 3 (Colony Forming Units / cubic meter). The first bacterial concentration threshold and the second bacterial concentration threshold can be set according to actual needs, with the first bacterial concentration threshold being 1000 CFU / m 3 The second bacterial concentration threshold is 100 CFU / m 3 For example, when the bacterial concentration exceeds the standard (such as >1000 CFU / m 3), turn on the sterilization and odor removal ion generator + fan, the fan circulates the air at a constant wind speed, so that the ozone is evenly distributed in the refrigerator space until the bacterial concentration is ≤100CFU / m 3 Turn off the ozone generating module and fan at the same time to avoid excessive sterilization.

[0040] In the embodiments of the present application, an odor gas sensor can be used to detect the concentration of odorous gases in parts per billion (ppb). Odorous gases include, but are not limited to, amine gases and thiol gases. The first and second odorous gas concentration thresholds can be set based on actual needs. For example, if the first odorous gas concentration threshold is 50 ppb and the second odorous gas concentration threshold is 10 ppb, when the odorous gas concentration exceeds the limit (e.g., >50 ppb), the negative ion generator is turned on and remains off until the odor concentration is ≤10 ppb.

[0041] This application independently monitors bacteria and odors to avoid "one-size-fits-all" energy waste. It can accurately sterilize and remove odors while avoiding excessive sterilization and reducing energy consumption.

[0042] Optionally, the rate of change of bacterial concentration can be combined to predict the spoilage time of food, and then the user can be reminded in stages and levels before the spoilage time is reached.

[0043] Optionally, a multi-zone odor sensor array can be provided to accurately identify the shelf where the odor originates and alert the user.

[0044] In an optional embodiment, taking the triggering of detecting that food is placed in the refrigerator as an example, the sterilizing and odor-removing process of the refrigerator further includes:

[0045] When detecting that food is placed in the refrigerator, identifying the type of the food;

[0046] Determining a target storage area that matches the type of food, and issuing instruction information of the target storage area to instruct the user to place the food into the target storage area;

[0047] Collecting food information of the food and environmental information of the target storage area;

[0048] Determining the operating time of the sterilization and odor removal module based on the food information and the environmental information;

[0049] The operation of the sterilization and odor removal module is controlled according to the operation time.

[0050] In an embodiment of the present application, when it is detected that the food is put in, the type of food (such as meat, fruits and vegetables, and cooked food) is identified through an image recognition unit (such as a camera) or a weight sensor. According to the type of food, the system lights up the corresponding shelf indicator light (such as meat corresponds to the second shelf), and the screen displays "Please put meat in the second layer". After the user puts the food into the corresponding target storage area, the food information and the environmental information of the target storage area are collected. The food information is collected, such as detecting the weight of the food through a weight sensor (such as 2kg), confirming the type (beef) through image recognition, and collecting the environmental information of the target storage area, such as detecting the temperature of the refrigerator at 4°C through a temperature sensor, detecting the humidity of the refrigerator at 70% through a humidity sensor, and reading the longest storage time that can be stored in all the food stored on the shelf through a timing unit (such as under storage conditions of about 2-8°C, the shelf stores fresh pork, fresh chicken, and fresh beef, among which fresh beef can be stored the longest, about 4 days, which is the longest storage time). Furthermore, based on the above-mentioned food information and environmental information, the running time of the sterilization and deodorization module is calculated, and finally the sterilization and deodorization module is run according to the calculated running time.

[0051] Take the example of a user putting 1.5kg of chicken breast (meat) into the refrigerator. Specifically, when the user puts the chicken breast into the refrigerator, the image recognition unit identifies it as "poultry meat". The system lights up the indicator light on the second shelf to prompt the user to place it. The weight sensor detects the weight of the chicken breast as 1.5kg. The timing unit shows that the longest storage time of all the ingredients stored on this shelf is 3 days, the temperature is 5°C, and the humidity is 65%. The calculation unit calculates the running time according to the formula: basic time 25 minutes + weight effect (1.5kg>1kg, add 8 minutes) + maximum storage time effect (3 days>2 days, add 5 minutes) + temperature and humidity correction (+2 minutes) = 40 minutes. The sterilization module on the second shelf stops after running for 40 minutes.

[0052] This application guides users to store food ingredients by category to avoid cross-contamination caused by mixing, dynamically adjusts the sterilization time according to the characteristics of the ingredients (such as meat is prone to breeding bacteria and requires a longer sterilization time), improves the sterilization efficiency, and intelligently adapts to environmental parameters (such as high temperature and high humidity accelerate spoilage) to ensure the sterilization effect in different scenarios.

[0053] In an optional embodiment, determining the running time of the sterilization and odor removal module based on the food information and the environmental information includes:

[0054] determining at least one impact duration based on the weight of the food, the type of food, the ambient temperature and humidity of the target storage area, and the longest storage duration that can be stored among all food ingredients in the target storage area, wherein the food information includes at least one of the weight of the food and the type of food, and the ambient information includes at least one of the ambient temperature, the ambient humidity, and the longest storage duration that can be stored among all food ingredients in the target storage area;

[0055] The sum of the basic duration and at least one of the impact durations is calculated to obtain the running duration.

[0056] In the embodiment of the present application, taking into account that different types of ingredients, different weights of ingredients, the longest storage time that can be stored in all ingredients in the target storage area, and temperature and humidity will affect the working time of the sterilization and odor removal module, therefore, in the embodiment of the present application, the running time of the sterilization and odor removal module can be calculated according to the calculation logic of total time = basic time + ∑ affected time (weight / type / storage time impact / temperature correction / humidity correction).

[0057] This application accurately matches sterilization requirements through multi-dimensional parameters (weight, type, temperature and humidity, etc.) to avoid insufficient or excessive sterilization, and uses a dynamic calculation mechanism to adapt to different food combinations (such as taking the minimum tolerance coefficient when storing multiple types of meat together) to protect the quality of the food.

[0058] In an optional embodiment, determining at least one impact duration based on the weight of the food, the type of the food, the ambient temperature and humidity of the target storage area, and the longest storage duration of all food in the target storage area includes at least one of the following:

[0059] Determining the duration of the food weight impact corresponding to the food type according to the food weight;

[0060] Determining the duration of the impact of the type of ingredients based on the type of ingredients;

[0061] Determining the storage time impact duration according to the longest storage duration that can be stored among all the food ingredients in the target storage area;

[0062] determining the duration of the ambient temperature impact according to the ambient temperature;

[0063] The duration of the environmental humidity impact is determined according to the environmental humidity.

[0064] In the embodiment of the present application, the running time of the sterilization and odor removal module = basic time + ∑ impact time (weight / type / storage time impact / temperature correction / humidity correction). Preferably, the running time of the sterilization and odor removal module t1 can be = basic time t2 + food weight impact time t3 corresponding to the food type + food type impact time t4 + storage time impact time t5 + ambient temperature impact time t6 + ambient humidity impact time t7.

[0065] In the embodiments of the present application, the effects of different types of food ingredients, different food ingredient weights, the longest storage time of all food ingredients, and temperature and humidity on the working time of the sterilization and deodorization module can be determined based on a large number of experiments and can also be set according to actual needs.

[0066] As a preference, you can set it up as follows:

[0067] The basic duration t2 is the set value, which is the minimum opening duration of the sterilization and odor removal module.

[0068] The weight-dependent duration t3 of the food type can be calculated based on the ratio of the measured weight to the preset weight. Specifically, when the weight is set to m1, the operating time is t1'. When the measured weight is m, t3 = (m / m1) * t1'. For example, if the weight is set to 50g and the operating time is 5 minutes, then when the measured weight is 60g, the sterilization and odor removal module's operating time is t3 = (60 / 50) * 5 = 6 minutes.

[0069] The duration t4 affected by the type of food can be calculated according to the basic duration tkind*type coefficient Y set for different types of food, that is, t4=tkind*Y. The basic duration tkind set for different types of food is different, and can be set according to actual needs. Different types are assigned different coefficients, such as the fish coefficient is 1, the chicken coefficient is 1.2, and the livestock meat coefficient is 1.3. In addition, if the target storage area stores multiple types of food, the type with the smallest coefficient is assigned. For example, if the target storage area stores beef, chicken, and crucian carp, among which the fish type coefficient is the smallest, the basic duration of 3 minutes set for fish is assigned to tkind, and the fish type coefficient 1 is assigned to Y, then the duration t4 affected by the type of food=3*1=3 minutes.

[0070] In view of the different characteristics of different fruits and vegetables, such as fruits and vegetables with harder skin and high water content require longer sterilization time, and some fruits and vegetables with thinner skin are prone to over-sterilization. The type coefficient of fruits and vegetables can be set as shown in Table 1.

[0071] Table 1

[0072]

[0073] The type coefficients of cooked food ingredients can be set as shown in Table 2.

[0074] Table 2

[0075] Deli meats Cooked vegetables Mixed cooked food 1.2 1 1.5

[0076] The storage time impact duration t5 can be calculated based on the ratio of the longest storage duration of all ingredients in the target storage area to the preset duration. Specifically, when the longest storage duration is set to d1, the operating duration is t2'. When the actual longest storage duration is d, t5 = (d / d1) * t2'. For example, if the longest storage period (maximum storage period) of all ingredients stored in the target storage area is 7 days, and the storage period is set to 4 days, the operating duration is 4 minutes. Then, when the storage period is 7 days, the operating duration of the sterilization and odor removal module is t5 = 4 * (7 / 4) = 7 minutes.

[0077] The ambient temperature impact time t6 can be calculated according to the temperature change. Specifically, when the set temperature is T1, the working time is t3′. When the measured ambient temperature is T, the correction coefficient Q1 is determined according to the temperature change △T=T-T1, t6=the set temperature impact basic time ttemperature*Q1. The set temperature impact basic time ttemperature can be set according to actual needs.

[0078] The correction coefficient Q1 is determined based on the temperature change ΔT = T-T1. Specifically, when the temperature change ΔT ≤ 5°C, the Q1 value range is 0 < Q1 ≤ 0.5. When the temperature change ΔT > 5°C, the Q1 value range is 0.5 < Q1 < 1. For example, if the basic temperature impact duration ttemperature is set to 1 minute, when the temperature change ΔT is 3°C, Q1 = 0.3, and the ambient temperature impact duration t6 = 1 minute * 0.3 = 0.3 minutes. When the temperature change is 10°C, Q1 = 0.8, and the ambient temperature impact duration t6 = 1 minute * 0.8 = 0.8 minutes.

[0079] The duration t7 of environmental humidity impact can be calculated according to the humidity change. Specifically, when the humidity is set to R1, the working time is t4′. When the measured environmental humidity is R, the correction coefficient Q2 is determined according to the humidity change △R=R-R1, t7=the set basic duration of humidity impact thumidity*Q2. The set basic duration of humidity impact thumidity can be set according to actual needs.

[0080] The correction coefficient Q2 is determined based on the humidity change (ΔR = R - R1). Specifically, when the humidity change (ΔR ≤ 20%), the Q2 value range is 0 < Q2 ≤ 0.5. When the humidity change (ΔR > 20%), the Q2 value range is 0.5 < Q2 < 1. For example, if the humidity impact base duration thumidity is set to 2 minutes, when the humidity change is 10%, Q2 is assigned a value of 0.2. At this time, the ambient humidity impact duration t7 = 2 minutes * 0.2 = 0.4 minutes. When the humidity change is 30%, Q2 is assigned a value of 0.6. At this time, the ambient temperature impact duration t7 = 2 minutes * 0.6 = 1.2 minutes.

[0081] In the embodiment of the present application, a safety upper limit can be set for the working time of the sterilization and odor removal module. When the working time of the sterilization and odor removal module reaches the safety upper limit, the sterilization and odor removal module is turned off.

[0082] This application flexibly adjusts the working time of the sterilization and odor removal module according to different food characteristics and environmental conditions, thereby reducing damage to food while ensuring the sterilization effect and improving storage quality.

[0083] In an optional embodiment, when the residual ozone exists and the ozone concentration of the residual ozone reaches a first threshold, performing the ozone elimination operation includes:

[0084] Turn on the photocatalyst lamp to irradiate the photocatalyst coating to generate strong oxidizing free radicals;

[0085] The fan is turned on to continuously deliver the air containing the residual ozone to the surface of the photocatalyst coating, so that the residual ozone reacts with the strong oxidizing free radicals to decompose.

[0086] In the embodiment of the present application, ozone elimination can be performed by means of a fan, ozone elimination water, photocatalyst, etc. Taking photocatalyst as an example, a photocatalyst lamp (ultraviolet lamp with a wavelength of 254nm) can be turned on to irradiate the photocatalyst coating to stimulate the generation of hydroxyl radicals (·OH) and superoxide anions (O2 - The photocatalyst coating can be a titanium dioxide coating. When ultraviolet light irradiates the photocatalyst coating, electron-hole pairs are generated on the coating surface, which react with oxygen and water molecules in the air to generate hydroxyl radicals (·OH) and superoxide anion radicals (O 2- ). These strong oxidizing free radicals can undergo redox reactions with ozone (O3), decomposing it into harmless oxygen (O2).

[0087] In this embodiment, a fan can be incorporated to force air flow, continuously delivering ozone-containing air to the photocatalyst coating surface, thereby expanding the contact area and accelerating the reaction process. For example, ozone-containing air is drawn in through the air inlet of the sterilization, deodorization, and ozone elimination device; propelled by a circulating fan, it flows through the photocatalyst coating area, where the ozone is decomposed; and the treated clean air is discharged from the sterilization, deodorization, and ozone elimination device outlet and returned to the refrigerator's cold storage compartment.

[0088] In the embodiment of the present application, an ozone concentration sensor can be set to conduct continuous detection. When the detection value drops to a safety threshold, the photocatalyst lamp and the fan are automatically turned off to stop the ozone elimination process.

[0089] This application utilizes photocatalysts to catalyze and decompose ozone without secondary pollution, and combines the synergistic effect of fans and photocatalysts to improve the efficiency of ozone elimination.

[0090] In an optional embodiment, after performing the ozone elimination operation, the method further includes emitting essential oil in a predetermined pattern when the ozone concentration of the residual ozone decreases to a preset concentration threshold, including:

[0091] operating the essential oil heater at a first power and turning on the fan to diffuse the essential oil in a high diffusion mode;

[0092] When the operating time of the essential oil heater in the high emission mode reaches a first preset time, or the temperature of the essential oil heater reaches a preset temperature, turning off the essential oil heater and the fan to enable the refrigerator to enter a normal operating mode;

[0093] When the refrigerator is in the normal operating mode and the closing time of the refrigerator door reaches a second preset time, or the closing time of the essential oil heater reaches the second preset time, the essential oil heater is operated at a second power and the fan is turned on to emit essential oil in a low emission mode, wherein the second power is less than the first power;

[0094] When the operating time of the essential oil heater in the low emission mode reaches a third preset time or the temperature of the essential oil heater reaches the preset temperature, the essential oil heater and the fan are turned off.

[0095] In an embodiment of the present application, the essential oil emission mode may include a high emission mode and a low emission mode. When the ozone elimination operation is performed to reduce the ozone concentration of the residual ozone to a preset concentration threshold, the essential oil can be emitted according to the high emission mode, that is, the predetermined mode. The preset concentration threshold can be set according to actual needs.

[0096] In the embodiment of the present application, in the high emission mode, the essential oil heater heats the bottom of the essential oil container at a first power (such as 50W) to vaporize the essential oil; the fan is turned on synchronously to set the wind speed to 5m / s. 3 / h diffuses the aroma, and lasts for the first preset time a1 = 20 minutes. When 20 minutes is reached or the temperature of the essential oil heater reaches the preset upper limit (such as 60°C), heating is stopped immediately to avoid carbonization of the essential oil. After the high-diffusion mode ends, the refrigerator enters the normal operating mode and starts the timing unit: if the refrigerator door is closed for more than a2 = 30 minutes in the normal operating mode, or the heater is turned off for more than a2 = 30 minutes, the low-diffusion mode is triggered. In the low-diffusion mode, the essential oil heater maintains low-temperature heating at a second power (such as 15W), and the fan runs intermittently (such as turning on for 2 minutes every 10 minutes) for a3 = 40 minutes. When 40 minutes are reached or the temperature of the essential oil heater reaches 60°C, it stops and enters the next cycle.

[0097] In an embodiment of the present application, before dispensing the essential oil, it is also possible to check whether the remaining amount of the essential oil has reached the lower limit.
