Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, in particular to a refrigerator odor control method and device, a refrigerator and a storage medium. BACKGROUND

[0002] As an indispensable food storage device in modern families and commercial environments, the internal air quality of a refrigerator directly affects the preservation effect of food and the user experience. Because the internal space of a refrigerator is closed and the temperature and humidity are suitable, food is prone to spoilage and deterioration during storage, producing odors and even breeding bacteria, which in turn affects the quality of other food. Therefore, refrigerator odor control technology has always been an important direction for home appliance research and development.

[0003] Current refrigerator odor control technologies on the market mainly include activated carbon adsorption, ultraviolet sterilization, ion purification and the like, but these methods have problems such as low purification efficiency, limited range of action, and inability to actively intervene in odor generation.

[0004] Activated carbon adsorption technology relies on physical adsorption principles to remove odor molecules in the air, but its adsorption capacity is limited and it is difficult to regenerate, requiring frequent replacement of filter cartridges and high maintenance costs.

[0005] Ultraviolet sterilization technology destroys the DNA structure of bacteria through ultraviolet light irradiation to achieve the purpose of sterilization, but its range of action is limited to specific areas and has no direct removal effect on odor molecules that have already been generated.

[0006] Ion purification technology releases positive and negative ions to combine with odor molecules in the air and settle, but the purification efficiency is low and ozone byproducts are easily produced in a closed space, posing a health risk.

[0007] In addition, some high-end refrigerator products attempt to introduce fragrance systems to improve the odor of the air inside the refrigerator. These systems usually use passive fragrance diffusion methods such as incense tablets, sachets, etc., and the release of fragrance is uncontrollable and the fragrance type is single. Some products use mechanical spraying or heating evaporation methods to release fragrance, but have problems such as high energy consumption, uneven fragrance distribution, and uncontrollable duration.

[0008] In view of the problem that the existing refrigerator odor control methods only adsorb or decompose odor after it has been generated, lacking real-time sensing and active intervention capabilities for odor changes, no effective solution has been proposed. SUMMARY

[0058] The optional embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0059] Embodiment 1

[0060] The refrigerator according to the embodiment of the present application is provided with an essential oil slow-release device, and the essential oil slow-release device is controlled to release essential oil into the refrigerator, so that the odor control of the refrigerator is achieved.

[0061] The essential oil slow-release device can be installed in the compartment of the refrigerator, for example, on the side wall of the refrigerating chamber.

[0062] The essential oil slow-release device comprises a plurality of chambers, and different chambers are used to place essential oils with different functions, for example, fresh covering type essential oil, neutralizing and decomposing type essential oil, bacteriostatic and preservative type essential oil, and adsorption and deodorization type essential oil.

[0063] In specific applications, the essential oil in a single chamber can be released alone, or the essential oil in at least two chambers can be released in combination, so as to meet the needs of different odor control scenes.

[0064] The essential oil slow-release device according to the embodiment comprises a plurality of independent chambers, and different chambers are used to place essential oils with different functions. The essential oils with different functions are independently stored to avoid cross contamination, and each chamber can independently release essential oil or release essential oil in combination, so as to achieve on-demand controllable release and achieve the diversification of essential oil functions and the accuracy of release control.

[0065] The essential oil slow-release device comprises a storage cabin and a mixing cabin, the storage cabin comprises a plurality of chambers, each chamber is in communication with the mixing cabin, and the mixing cabin is used to mix essential oil and release essential oil into the compartment. Through the arrangement of the storage cabin and the mixing cabin, the essential oils with different functions from different chambers can be mixed in the mixing cabin and then released into the compartment, so as to ensure the uniformity of essential oil mixing and thus ensure the required odor control effect.

[0066] Each chamber is provided with an atomizing component, and when it is necessary to start the chamber to release essential oil, the atomizing component of the chamber is turned on to atomize and release the essential oil in the chamber. Through atomization, the liquid essential oil can be broken into nanoscale droplets, so as to improve the diffusion efficiency and uniformity of the essential oil and release the fragrance in a low-dose and high-efficiency manner, thereby achieving efficient atomization and uniform diffusion of the essential oil.

[0067] The atomizing component can be a micro piezoelectric ceramic atomizing sheet, which can break the liquid essential oil into nanoscale droplets through high-frequency vibration, so as to achieve efficient, uniform and low-dose release. The atomizing component can also be an ultrasonic microporous atomizing sheet, which can meet the atomization needs of essential oils with higher viscosity.

[0068] Preferably, the storage cabin is located above the mixing cabin; the bottom of each chamber is provided with an atomizing component for atomizing the essential oil in the chamber; and the atomizing component is in communication with the mixing cabin through a mist outlet. The mixing cabin is located below, which is more conducive to the mixing and release of essential oil.

[0069] The outlet of the mixing cabin can be provided with an exhaust fan for driving the essential oil in the mixing cabin to be released into the compartment. By providing the exhaust fan, it is helpful to quickly release the essential oil into the compartment. The number of exhaust fans can be set according to actual needs. Preferably, in order to save energy, the exhaust fan is operated at a low power.

[0070] As shown in Figure 1 and Figure 2 , it is a schematic diagram of the essential oil slow-release device, taking three chambers as an example, the essential oil slow-release device 1 comprises a storage cabin 2 and a mixing cabin 3, the storage cabin 2 comprises a plurality of chambers, which are respectively a first chamber 4, a second chamber 5 and a third chamber 6.

[0071] The first chamber 4 is placed with fresh covering type essential oil, such as encapsulated lemon, orange and other citrus essential oil, the composition is terpene (such as limonene), the smell is fresh and lively, the volatility is strong, and it can quickly improve the fragrance intensity in the space and effectively cover the temporary mild odor.

[0072] The second chamber 5 is placed with neutralizing and decomposing type essential oil, such as encapsulated tea tree, eucalyptus and other essential oil, which contains eucalyptol, terpinen and other components, which has certain neutralizing and embedding effect on polar odor molecules such as sulfides (fishy smell) and amines (putrefactive smell).

[0073] The third chamber 6 is placed with bacteriostatic and antiseptic type essential oil, such as encapsulated peppermint, clove and other essential oil, among which menthol and eugenol have been widely studied and confirmed to have broad-spectrum antibacterial and antifungal activity, which can effectively inhibit the growth of common spoilage microorganisms.

[0074] The bottom of each chamber is provided with an atomizing component 8 for atomizing the essential oil in the chamber. The atomizing component 8 is communicated with the mixing cabin 3 through the atomizing outlet, and when the atomizing components 8 of multiple chambers are started, the essential oils with different functions can be released into the refrigerator compartment after being mixed in the mixing cabin 3. The outlet of the mixing cabin 3 is provided with an exhaust fan 7 for driving the essential oil in the mixing cabin 3 to be released into the compartment.

[0075] In actual application, a fourth chamber can also be provided to place adsorbing and deodorizing type essential oil, such as activated carbon composite essential oil, which is used to deal with high-concentration odor scenes.

[0076] As shown in Figure 3 , it is a schematic diagram of the refrigerator, the essential oil slow-release device 1 is arranged in the refrigerator compartment, and can be specifically installed on the side wall of the refrigerating chamber. The refrigerator compartment is also provided with a VOCs sensor 9, which can be specifically installed in the refrigerating chamber for detecting the VOCs concentration in the compartment. The VOCs concentration refers to the content or concentration level of volatile organic compounds (Volatile Organic Compounds) in the environment. The refrigerator can also be provided with a door opening and closing sensor for detecting the opening and closing state of the compartment door.

[0077] The embodiment can perceive environmental changes through the VOCs sensor and the door opening and closing sensor, and then trigger different modes according to different environmental scenes to release different essential oils, so as to realize timely and efficient refrigerator odor control.

[0078] The embodiment can also provide user individual customization function. The user can replace the essential oils pre-placed in each chamber with the essential oils required by the user according to actual needs, meet the user's individual odor preference, and flexibly adjust the aroma type and intensity according to the type of food stored by the user, for example, selecting strong fresh aroma when storing seafood, selecting soft aroma atmosphere when storing desserts, and selecting no odor when storing tea leaves, to flexibly meet the diversified needs of the user. The user can also freely set the required chamber to be started, to realize high individual customization.

[0079] Embodiment 2

[0080] The embodiment provides a refrigerator odor control method. The refrigerator chamber is provided with an essential oil slow-release device comprising a plurality of chambers. Different chambers are placed with essential oils of different functions. The odor control can be realized based on the essential oil slow-release device described in the above embodiment.

[0081] Figure 4 is a flowchart of the refrigerator odor control method provided by the embodiment of the application, as shown in Figure 4 The method comprises the following steps:

[0082] S401, after starting the odor control function, the essential oil release of the plurality of chambers is controlled to run the normal bacteria inhibition mode.

[0083] S402, the opening and closing state of the chamber door and the VOCs concentration in the chamber are detected.

[0084] S403, if the chamber door is detected to be opened, the essential oil release of the plurality of chambers is controlled to run the rapid freshening mode.

[0085] S404, if the VOCs concentration reaches the preset condition, the essential oil release of the plurality of chambers is controlled to run the emergency purification mode; wherein the chambers releasing essential oils are different in different modes.

[0086] In the embodiment, the refrigerator has an odor control function, and the working modes of the odor control function include: normal bacteria inhibition mode, rapid freshening mode and emergency purification mode.

[0087] The embodiment sets a multi-chamber essential oil slow-release device, different chambers are placed with essential oils of different functions, the essential oils of different functions can be independently released or combinedly released, various modes are realized, and different odor control scene requirements are met; a normal bacteriostasis mode is defaulted to run, bacteria and mold can be continuously inhibited from breeding, and generation of odor substances is slowed down; a rapid freshening mode is triggered based on an opening and closing state of a chamber door to actively intervene in generation of odor, an emergency purification mode is triggered based on a VOCs concentration in the chamber to timely remove a pollution source, the refrigerator internal environment changes can be intelligently sensed, and an odor control strategy is automatically adjusted according to the environment changes, aroma release is intelligently regulated, response speed and control precision of the refrigerator odor control are improved, and the problem that odor control is lagged due to the refrigerator odor control mode being unable to actively intervene in generation of odor in the prior art is solved.

[0088] In the normal bacteriostasis mode, the essential oil slow-release device releases the bacteriostasis and preservation type essential oil to the chamber.

[0089] Specifically, the essential oil release of the plurality of chambers is controlled to run the normal bacteriostasis mode, including: periodically starting the chamber placed with the bacteriostasis and preservation type essential oil to release the essential oil, and after each time of continuously releasing for a first preset time, the chamber is controlled to stop releasing.

[0090] The period and the first preset time can be set according to actual conditions, for example, the period is 30 min, and the first preset time is 10 s, that is, the chamber placed with the bacteriostasis and preservation type essential oil is started to release for 10 s every 30 min.

[0091] In the normal bacteriostasis mode, only the chamber placed with the bacteriostasis and preservation type essential oil is periodically started, and other chambers are all closed and do not release the essential oil.

[0092] In the embodiment, the normal bacteriostasis mode is a default mode, runs at extremely low power consumption, periodically releases the bacteriostasis and preservation type essential oil, continuously maintains a low-concentration "bacteriostasis microenvironment" in the refrigerator, and continuously inhibits bacteria and mold from breeding, thereby slowing down generation of odor substances from the root.

[0093] In the rapid freshening mode, the essential oil slow-release device releases a mixture of the freshening masking type essential oil and the neutralization and decomposition type essential oil.

[0094] Specifically, the essential oil release of the plurality of chambers is controlled to run the rapid freshening mode, including:

[0095] The chamber placed with the freshening masking type essential oil and the chamber placed with the neutralization and decomposition type essential oil are started to release the essential oil;

[0096] When the second preset time is reached, the normal bacteriostasis mode is switched to.

[0097] The second preset time is the shortest time required for releasing the fragrance to achieve the purpose of covering the odor, and can be set according to actual conditions. For example, the second preset time is 30 seconds.

[0098] In the quick freshening mode, only the chamber in which the freshening covering type essential oil is placed and the chamber in which the neutralizing and decomposing type essential oil is placed are started, and the other chambers are closed and do not release the essential oil.

[0099] In this embodiment, the quick freshening mode is triggered by an opening door event. When the chamber door is opened, the chamber in which the freshening covering type essential oil is placed and the chamber in which the neutralizing and decomposing type essential oil is placed are immediately started to continuously release the essential oil for a second preset time, so as to quickly establish a strong and pleasant fragrance background, actively prevent and cover any discordant odor, actively intervene in the generation of the odor, and timely respond to achieve timeliness and efficiency of odor control.

[0100] During the operation of the quick freshening mode, if it is detected that the chamber door is closed and the second preset time is not reached, the quick freshening mode is still continued to operate.

[0101] For example, the user opens the chamber door and puts a durian into the refrigerator. The opening door action triggers the quick freshening mode, and the essential oil is released to cover the odor of the durian, so as to actively intervene in the odor.

[0102] The preset condition includes that the VOCs concentration change rate is greater than or equal to a preset threshold value and the VOCs concentration is greater than or equal to a first concentration threshold value.

[0103] The preset threshold value and the first concentration threshold value can be set according to actual conditions.

[0104] For example, the VOCs concentration is detected every 30 seconds, and the VOCs concentration average change rate in each period is calculated with 5 minutes as a period, compared with the preset threshold value, and the VOCs concentration change is measured.

[0105] In the emergency purification mode, the essential oil slow-release device releases a mixture of the neutralizing and decomposing type essential oil and the bacteriostatic and preservative type essential oil.

[0106] Specifically, the essential oil release of the plurality of chambers is controlled to operate the emergency purification mode, including:

[0107] The chamber in which the neutralizing and decomposing type essential oil is placed and the chamber in which the bacteriostatic and preservative type essential oil is placed are started to release the essential oil.

[0108] When the VOCs concentration is less than or equal to a second concentration threshold value, the normal bacteriostatic mode is switched to.

[0109] The second concentration threshold can be set according to actual conditions, and the second concentration threshold is less than the first concentration threshold.

[0110] In the emergency purification mode, only the chambers containing the neutralizing and decomposing essential oil and the chambers containing the bacteriostatic and preservative essential oil are started, and the other chambers are closed and do not release essential oil.

[0111] In the present embodiment, the emergency purification mode is triggered by a VOCs concentration surge event. When the VOCs concentration in the chamber is detected to rapidly rise and be greater than or equal to the first concentration threshold, it indicates that food may begin to spoil or strong-smelling food materials (such as durians or onions) are added. The chambers containing the neutralizing and decomposing essential oil and the chambers containing the bacteriostatic and preservative essential oil are immediately started to continuously release essential oil, neutralize the odor molecules generated, inhibit the growth of bacteria to enhance the bacteriostatic effect, reduce the spoilage rate of food, and perform point removal of the pollution source, thereby achieving timeliness and high efficiency of odor control.

[0112] The present embodiment can achieve multiple functions such as bacteriostasis, freshness, and odor neutralization by setting a multi-chamber essential oil slow-release device to independently release or combine the release of essential oils with different functions.

[0113] In one embodiment, each chamber is provided with an atomization component. When it is necessary to start the chamber to release essential oil, the atomization component of the chamber is turned on to release the essential oil in the chamber after atomization. If it is necessary to start at least two chambers to release essential oil, the essential oils after atomization of the at least two chambers are mixed and then released to the chamber.

[0114] The present embodiment can break liquid essential oil into nanoscale droplets through atomization, improve the diffusion efficiency and uniformity of essential oil, release fragrance with low dosage and high efficiency, and achieve efficient atomization and uniform diffusion of essential oil. Atomization helps the rapid mixing of essential oils with different functions.

[0115] To meet the individual needs of users, in one embodiment, the method further comprises: entering a personalized mode in response to a user operation; and in the personalized mode, starting the corresponding chambers to release essential oil according to the instruction information input by the user, and the essential oil in each chamber can be replaced with the essential oil required by the user.

[0116] The personalized mode is triggered by the user, for example, the user replaces the required essential oil and customizes the fragrance mode according to the actual needs through the mobile phone APP or the user interaction interface of the refrigerator panel, thereby realizing personalized odor management.

[0117] In the individual customization mode, the user can replace the essential oil pre-placed in each chamber with the essential oil required by the user according to the actual needs (for example, personal preferences or the types of stored food materials, etc.), and freely select the required enabled chamber or chamber combination, flexibly adjust the aroma type and intensity according to the user's needs, and realize high individual customization.

[0118] As Figure 5 shown, a specific flowchart of the refrigerator odor control method provided by the embodiment of the application includes the following steps:

[0119] S501, start the odor control function.

[0120] S502, run the normal bacteriostatic mode by default, for example, start the atomization component of the chamber with the bacteriostatic and preservative essential oil every F time for T1 time.

[0121] S503, detect the opening and closing state of the chamber door through the sensor, determine whether the chamber door is opened, if yes, go to S504, if no, go to S506.

[0122] S504, run the quick freshening mode.

[0123] S505, in the quick freshening mode, determine whether the running time reaches T2, if yes, switch to the normal bacteriostatic mode, i.e., return to S502, if no, return to S054 to continue running the quick freshening mode.

[0124] S506, detect the VOCs concentration in the chamber through the sensor, for example, detect the VOCs concentration C in the chamber every 30s, and calculate the average change rate P of the VOCs concentration in each period with 5min as a period.

[0125] S507, determine whether P≥P0 is met, if yes, go to S508, if no, return to S502 to continue running the normal bacteriostatic mode.

[0126] S508, determine whether C≥C1 is met, if yes, go to S509, if no, return to S502 to continue running the normal bacteriostatic mode.

[0127] S509, run the emergency purification mode.

[0128] S510, in the emergency purification mode, determine whether C≤C2 is met, if yes, switch to the normal bacteriostatic mode, i.e., return to S502, if no, return to S509 to continue running the emergency purification mode.

[0129] F represents the start period of the normal bacteriostatic mode, T1 represents the first preset time, and T2 represents the second preset time.

[0130] P0 represents a preset threshold. C1 represents a first concentration threshold, and C2 represents a second concentration threshold, C2 < C1.

[0131] For example, 15 min ≤ F ≤ 30 min, 10 s ≤ T1 ≤ 30 s, 30 s ≤ T2 ≤ 120 s, 5 ppm ≤ C1 ≤ 10 ppm, 0.5 ppm ≤ C2 ≤ 2 ppm, and 0.5 ppm / min ≤ P0 ≤ 4 ppm / min.

[0132] After the refrigerator starts the odor control function, the normal bacteria inhibition mode is run by default. The opening and closing state of the chamber door and the VOCs concentration in the chamber are detected by a sensor. If the chamber door is detected to be opened, the quick freshening mode is immediately run. After the quick freshening mode is run for a certain period of time, the normal bacteria inhibition mode is switched to. If the VOCs concentration change rate is greater than or equal to a preset threshold and the VOCs concentration is greater than or equal to a first concentration threshold, the emergency purification mode is immediately run. When the VOCs concentration is less than or equal to a second concentration threshold, the normal bacteria inhibition mode is switched to.

[0133] The step S503 is to determine whether the trigger condition of the quick freshening mode is met, and the steps S506 to S508 are to determine whether the trigger condition of the emergency purification mode is met. The determination order of the two trigger conditions can be changed or can be performed simultaneously. The execution order of the steps S507 and S508 can be changed or can be performed simultaneously.
