[0023] In order to more clearly illustrate the technical solution of the present application, the drawings required for use in the embodiments are briefly introduced below. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0024] Figure 1 A flow chart of a method for purifying refrigerator odor provided in an embodiment of the present application. DETAILED DESCRIPTION

[0025] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0026] With the improvement of people's living standards, refrigerators have entered thousands of households and become a necessity in people's daily lives. In order to meet the diverse needs of users, different types of refrigerators provide a variety of capacities and refrigeration methods. Large-capacity air-cooled refrigerators have become the main choice of most users due to their large capacity and multiple functions.

[0027] At present, people have higher and higher requirements for the five senses experience of refrigerators, among which the problem of refrigerator odor has gradually attracted the attention of users. At present, refrigerator odors are divided into odors during use and unpacking odors. Unpacking odors refer to the offensive odors emitted from the sealed refrigerator that users feel when they open the refrigerator door after the new refrigerator arrives at the user's home, unpack the outer packaging, and open the refrigerator door. In order to improve the user's first impression and improve the problem of refrigerator unpacking odors, the industry currently mainly adopts methods such as increasing the odor dissipation time of parts, adding odor-free packages with adsorption effects such as activated carbon, and replacing low-odor materials.

[0028] However, increasing the time for parts to deodorize will affect the normal production rhythm and increase inventory, while the deodorization effect is not obvious; placing odor-removing bags with adsorption effects such as activated carbon in the refrigerator is costly and difficult to promote and apply on a large scale, and the activated carbon has a slow adsorption rate and is easily saturated, and cannot completely absorb the odor in the refrigerator; low-odor material substitution can remove odors in principle, but commonly used materials for refrigerators such as polyurethane foam, liner plastic parts, and EPS foam are all industry-standard materials or cost-effective materials. It is difficult to find suitable low-odor material substitutes, and low-odor materials are generally expensive.

[0029] Based on this, the present application provides a method for purifying refrigerator odors. The method for purifying refrigerator odors provided in the present application releases purified gas through the flavor gel in the slow-release component, which can completely absorb the odor in the refrigerator. The components in the flavor gel used in the present application meet food grade requirements. The present application uses a slow-release component with small holes for packaging. On the one hand, the flavor release rate is controlled by the size of the pores, and at the same time, the flavor gel is blocked from penetrating into the plastic inside the refrigerator to cause pollution.

[0030] In some embodiments, Figure 1 As shown, the present application provides a method for purifying refrigerator odor, the method comprising:

[0031] Get the door status of the refrigerator storage room door;

[0032] When the storage chamber door is in a closed state, detecting the concentration of odor molecules;

[0033] When the concentration of the odor molecules is greater than or equal to the preset concentration value, the slow-release component is controlled to release the purified gas; the slow-release component contains the scent gel, and the viscosity of the scent gel is 35-50Pa.s.

[0034] In some embodiments, obtaining the door status of the refrigerator storage compartment door includes:

[0035] When the door of the storage chamber is in a closed state and the concentration of the odor molecules is greater than or equal to a preset concentration value, the slow-release component is controlled to perform a purification operation according to a first rule; the first rule is to control the slow-release component to run a preset number of purification cycles within a preset time length;

[0036] When the state of the door of the storage chamber changes, the slow-release component is controlled to perform the purification operation according to the second rule; the second rule is to control the slow-release component to stop performing the purification operation when it is detected that a termination condition is met.

[0037] When the storage chamber door is in a closed state and the concentration of odor molecules is greater than or equal to a preset concentration value, the electric valves on both sides of the slow-release component are controlled to start, so that the slow-release component releases purified gas from the small holes.

[0038] The on / off control of the slow-release component is divided into two control logics: the first rule (automatic control) and the second rule (door opening and closing control). When the door of the storage room is not open, the slow-release component runs a preset number of purification cycles within a preset time. In some embodiments, the slow-release component automatically shuts down after working for a maximum of 3 cycles.

[0039] When the door of the storage chamber is always in the closed state within the first time period, the slow-release component operates according to the first rule. If the door of the storage chamber is detected to have changed again, the controller controls the electric valves on both sides of the slow-release component to open and operate according to the established rule. The established rule is that when the termination condition is met, the slow-release component is controlled to stop performing the purification operation. When the electric valves on both sides of the slow-release component are started, the controller in the refrigerator starts the timing operation, compares the timing duration with the preset duration, and determines that the termination condition is met when the timing duration reaches the preset duration.

[0040] In some embodiments, a small hole with a depth of 2-10 mm is reserved on the sustained-release component. The small hole is a round hole or a square hole. The area of ​​the small hole is 25-30 mm. 2 .

[0041] In some embodiments, the flavor gel comprises, by weight: 2.0-5.0 parts of resin, 1.0-6.0 parts of wetting agent, 0.5-4.0 parts of essential oil, 0.5-6.0 parts of solubilizer, 0.2-0.8 parts of thickener, 0.1-0.3 parts of preservative, and 80-98 parts of deionized water.

[0042] In some embodiments, the resin is one of agar powder, carrageenan, and carbomer.

[0043] In some embodiments, the wetting agent is at least one of glycerin, butylene glycol, pentylene glycol, hexylene glycol, and propylene glycol.

[0044] In some embodiments, the essential oil is at least one of naturally extracted essential oils such as lemon essential oil, orange essential oil, apple essential oil, and milk essential oil.

[0045] The main components of lemon essential oil used in this application include limonene, β-pinene, and γ-terpinene, which are carefully extracted from the peel. The essential oil is extracted mainly by cold pressing, and the oil yield is about 0.3% to 0.5% from the lemon peel. At the same time, essential oil can also be extracted from lemon leaves, and the oil yield is about 0.2% to 0.3%, using steam distillation.

[0046] The main components of the orange essential oil used in this application include limonene, linalool, pinolene, sabinene, myrcene, etc. These components give the orange essential oil a unique aroma and medicinal value. Limonene is one of the main components of orange essential oil and has a fresh citrus aroma. Linalool is an important aroma component that gives the essential oil a unique fragrance. Components such as pinolene and sabinene also have an important impact on the chemical properties and smell of the essential oil.

[0047] In addition, orange essential oil contains other chemical components, such as octanal, decanal, geranyl acetate, etc., which together constitute the complex chemical structure of orange essential oil. These components not only affect the aroma of essential oils, but also determine their effects in different applications. For example, limonene and linalool are widely used in edible flavors, while pinolene and sabinene may have specific therapeutic effects. Orange essential oil can be extracted by squeezing the peel of citrus plants.

[0048] The orange essential oil used in this application includes green orange essential oil, yellow orange essential oil and red orange essential oil. Green orange essential oil is extracted from the unripe stage of oranges, and its smell has a green and astringent feeling, and even a bitter leaf taste. Green orange essential oil does not contain furanocoumarins and has no photosensitivity.

[0049] Yellow tangerine essential oil comes from the semi-ripe stage of tangerines. It has a light floral scent and is the only citrus essential oil with a floral scent. Yellow tangerine essential oil is photosensitizing.

[0050] Tangerine essential oil is extracted from fully ripe oranges, and it exudes the sweet and fresh scent of oranges. When diffused, it can bring a warm feeling like sunlight. However, tangerine essential oil is also photosensitizing.

[0051] The main components of the apple essential oil used in this application include ester compounds, aldehyde compounds and other volatile components. Ester compounds such as amyl acetate, amyl butyrate, amyl valerate, etc. account for a large proportion in apple essence, usually reaching more than 50%. Aldehyde compounds such as citral, citronellal, etc., as auxiliary ingredients, modify the formula of apple essence. In addition, apple essential oil also contains alcohol compounds such as ethanol, phenylethanol, etc. These ingredients give apple essential oil a specific aroma and properties.

[0052] In the formula of apple flavor, ester compounds are the main ingredients, including amyl acetate, amyl butyrate, amyl valerate, ethyl butyrate, etc., which usually account for more than 50%. Other ingredients such as aldehyde compounds such as citral and citronellal are used as auxiliary agents to modify the formula of apple flavor. In addition, alcohol compounds such as ethanol and phenylethanol also play an important role in apple flavor.

[0053] The present application defines the essential oil components as lemon essential oil, orange essential oil, and apple essential oil, so that the scented gel used in the refrigerator can absorb and eliminate odor molecules in the air; at the same time, the scented gel can absorb and remove organic compounds in the air, such as odor or moldy smell. The scented gel can also dissolve some oily or sticky odors, disperse them in the air, and reduce the concentration of the odor. In addition, for some relatively strong or persistent odors, such as toxic gases released by pollutants or severe mold pollution.

[0054] In some embodiments, the solubilizer is at least one of polyglycerol fatty acid ester and hydrogenated castor oil; the thickener is at least one of sodium hydroxymethyl cellulose, sodium hydroxyethyl cellulose and sodium carboxymethyl cellulose.

[0055] In some embodiments, the preservative is at least one of sodium benzoate, kason, and phenoxyethanol.

[0056] In some embodiments, the preparation method of the flavored gel is as follows: adding the resin into a container according to the weight ratio, adding deionized water and heating to 85-95° C.;

[0057] After it is completely dissolved, stir at 300-500r / min for 10-15min, add the wetting agent, solubilizer, thickener and preservative and stir evenly, then cool to 45-60℃, add the essential oil and continue stirring evenly to obtain the scented fat.

[0058] In some embodiments, the present application provides a production process of the flavored cream in the above embodiments, comprising the following steps:

[0059] Step 1: Add the resin into a container according to the weight ratio, add deionized water and heat to 85-95°C;

[0060] Step 2: After it is completely dissolved, stir at 300-500r / min for 10-15min, add the wetting agent, solubilizer, thickener and preservative and stir evenly, then cool to 45-60℃, add the essential oil and continue stirring evenly to obtain the scented cream.

[0061] Example 1

[0062] A flavored gelled fat, comprising the following ingredients in the following weight ratio:

[0063]

[0064] Add agar powder into a container, add deionized water and heat to 85-95°C, stir at 300-500r / min for 10-15min after it is completely dissolved, add glycerin, polyglycerol fatty acid ester, sodium hydroxymethyl cellulose and sodium benzoate and stir evenly, then cool to 45-60°C, add lemon essential oil and continue stirring evenly to obtain a scented gel with a certain viscosity.

[0065] The essential oil used in the flavor gel for refrigerators provided in this application is edible flavor and meets food grade requirements. The exterior of the flavor gel provided in this application may be provided with a protective piece, which may be an EPS foam piece, an EPE foam piece, a paper-based protective piece, etc. A small hole with a depth of 2-10 mm is reserved in advance on the protective piece, which may be a round hole, a square hole or other shapes, with an area of ​​25 mm 2 When in use, place 0.05-0.2g of scented gel in the reserved position of the refrigerator interior protection part.

[0066] The present application controls the fragrance release rate by the pore size, and at the same time prevents the fragrance gel from penetrating into the plastic inside the refrigerator to cause pollution. The fragrance gel for refrigerators provided by the present application has a fast adsorption rate, is not easy to be saturated, can completely absorb the odor in the refrigerator, and plays a role in purifying the odor in the refrigerator.

[0067] In some embodiments, the present application also provides a purification device for executing the above-mentioned method for purifying refrigerator odor. The purification device for the refrigerator provided has a box body, an odor sensor, a slow-release component and a controller; the box body is provided with an odor sensor and a slow-release device, and the slow-release device stores the fragrance gel for the refrigerator in the above-mentioned embodiment; the controller is used to obtain the concentration of odor molecules in the target area of ​​the refrigerator according to the odor sensor, and when the concentration of the target odor molecules is greater than or equal to the preset concentration value, the slow-release component is controlled to release the purified gas.

[0068] By placing the purification device for refrigerators inside the refrigerator, the odor sensor monitors the odor molecules in the target area in real time and detects the concentration of the odor molecules. When the concentration of the target odor molecules is greater than or equal to the preset concentration value, the slow-release component is controlled to release the purified gas, thereby improving the efficiency of refrigerator purification. After the odor is removed, it is not easy to breed, thereby improving the user experience.

[0069] In some embodiments, the odor sensor in the purification device of the refrigerator is used to detect odorous gas in the food storage area. After the odor sensor detects the odorous gas, it sends a signal. The controller receives the signal sent by the odor sensor and controls the slow-release component to work. The odor sensor is a reducing sensor. The chemical adsorption material in the sensor combines with the reducing gas, so that the odor sensor is reduced and detects the odorous gas, and sends a signal to the controller. Specifically, in some embodiments, the odor sensor is set as a metal oxide sensor that can be reduced to change the resistance value, releases reducing gas (organic polymer gas), and when the reducing gas passes through, the reducing gas will capture the oxygen atoms on the odor sensor, thereby changing the resistance value of the odor sensor, that is, realizing the detection work of the odor sensor.

[0070] The purification device for refrigerators provided in the present application uses an odor sensor to detect odorous gas in the food storage area. After the odor sensor detects the odorous gas, it sends a signal; the controller receives the signal sent by the odor sensor and controls the slow-release component to work. When working, the odor sensor detects whether there is odorous gas in the food storage area. After detecting the odorous gas, it sends a signal to the controller, and the controller controls the slow-release component to start working to release the purified gas to purify the food storage area until there is no odorous gas in the food storage area. The above-mentioned settings can realize the purification process in the refrigerator and improve the safety of refrigerator use.

[0071] It can be seen from the above embodiments that the present application provides a method for purifying refrigerator odors, the method comprising: obtaining the door state of the refrigerator storage compartment door; when the storage compartment door state is in a closed state, detecting the concentration of odor molecules; when the concentration of the odor molecules is greater than or equal to a preset concentration value, controlling the slow-release component to release the purified gas; the slow-release component contains a scented gel, and the viscosity of the scented gel is 35-50 Pa.s. The scented gel in the present application includes, by weight, 2.0-5.0 parts of resin, 1.0-6.0 parts of wetting agent, 0.5-4.0 parts of essential oil, 0.5-6.0 parts of solubilizer, 0.2-0.8 parts of thickener, 0.1-0.3 parts of preservative, and 80-98 parts of deionized water. Through the method for purifying refrigerator odors, the air inside the refrigerator is purified during the transportation of the refrigerator. The scented gel used in the present application can slowly emit fragrance and cover the odor generated during the storage and transportation of the refrigerator. The fragrance is a plant extract essence, which is safe and reliable.
