TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, in particular to a method for purifying peculiar smell of a refrigerator. BACKGROUND

[0002] With the improvement of people's living standards, refrigerators have entered thousands of households and become a necessity in people's daily life. In order to meet the diversified needs of users, different types of refrigerators provide multiple volumes and multiple cooling methods. Large-capacity air-cooled refrigerators have become the main choice of most users due to their large capacity, multiple functions and other advantages.

[0003] At present, people have higher and higher requirements for the five-sense experience of refrigerators, among which the peculiar smell of the refrigerator gradually attracts the attention of users. The peculiar smell of the refrigerator is divided into peculiar smell in use and peculiar smell when opening the box, wherein the peculiar smell when opening the box refers to the unpleasant smell emitted from the closed refrigerator at the moment when the user opens the refrigerator door after unpacking the outer package of the new refrigerator. In order to improve the first impression of users and improve the peculiar smell problem of refrigerators when opening the box, the industry currently mainly adopts the following ways: increasing the odor dispersion time of parts, putting odor-removing packages with adsorption function such as activated carbon, replacing low-odor materials, etc.

[0004] However, increasing the odor dispersion time of parts will affect the normal production rhythm, increase the inventory, and the odor dispersion effect is not obvious; putting odor-removing packages with adsorption function such as activated carbon in the refrigerator has high cost and is difficult to be widely applied, and the adsorption rate of activated carbon is slow and easy to be saturated, which cannot completely adsorb the peculiar smell in the refrigerator, resulting in that the peculiar smell still remains in the refrigerator. SUMMARY

[0005] The present application provides a method for purifying peculiar smell of a refrigerator to solve the problem that the peculiar smell in the refrigerator still remains in the prior art because the peculiar smell adsorbing material of the refrigerator cannot completely adsorb the peculiar smell in the refrigerator.

[0023] To more clearly illustrate the technical solution of this application, the drawings used in the embodiments will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0024] Figure 1 A flowchart illustrating a method for purifying refrigerator odors provided in an embodiment of this application. Detailed Implementation

[0025] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0026] With the improvement of people's living standards, refrigerators have become a common household item and a necessity in daily life. To meet the diverse needs of users, different types of refrigerators offer various capacities and cooling methods. Large-capacity, air-cooled refrigerators, due to their large capacity and multiple functions, have become the primary choice for most users.

[0027] People are increasingly demanding a superior sensory experience with refrigerators, and refrigerator odors are gradually gaining attention. Currently, refrigerator odors are categorized into odors during use and odors upon opening the box. Opening the box odor refers to the unpleasant smell emanating from the sealed refrigerator the moment the door is opened after the new refrigerator arrives at the user's home. To improve the user's first impression and address the issue of opening the box odor, the industry primarily employs methods such as increasing the time for components to dissipate odors, placing odor-absorbing packets with adsorption properties like activated charcoal, and using low-odor materials as alternatives.

[0028] However, increasing the time for parts to dissipate odors will affect the normal production rhythm, increase inventory, and the odor dissipation effect is not obvious. Placing odor-removing bags with adsorption properties such as activated carbon in the refrigerator is expensive and difficult to promote and apply on a large scale. Moreover, activated carbon has a slow adsorption rate and is easily saturated, so it cannot completely adsorb the odors in the refrigerator. Theoretically, low-odor materials can remove odors, but commonly used refrigerator materials such as polyurethane foam, inner plastic parts, and EPS foam are all industry-standard materials or cost-effective materials, making it difficult to find suitable low-odor materials to replace them. In addition, low-odor materials are generally expensive.

[0029] Based on this, this application provides a method for purifying refrigerator odors. The method utilizes a fragrance gel in a slow-release component to release purifying gas, which can completely absorb odors inside the refrigerator. The components in the fragrance gel used in this application meet food-grade requirements. This application employs a slow-release component with small holes for packaging, which controls the fragrance release rate by controlling the pore size while preventing the fragrance gel from penetrating into the refrigerator's internal plastic and causing contamination.

[0030] In some embodiments, such as Figure 1 As shown, this application provides a method for purifying refrigerator odors, the method comprising:

[0031] Get the door status of the refrigerator's storage compartment door;

[0032] When the storage compartment door is closed, the concentration of odor molecules is detected;

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

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

[0035] When the storage compartment door is closed and the concentration of 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 purification cycle of a preset number of times within a preset time period;

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

[0037] When the storage compartment door is closed 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 activated to allow the slow-release component to release purified gas from the small hole.

[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 / closing control). When the storage room door is not open, the slow-release component runs a preset number of purification cycles within a preset time period. In some embodiments, the slow-release component automatically shuts off after working continuously for a maximum of three cycles.

[0039] If the refrigerator compartment door remains closed for the first duration, the slow-release component operates according to the first rule. If a change in the door's status is detected again, the controller opens the electric valves on both sides of the slow-release component, allowing it to operate according to a predetermined rule. This predetermined rule is that the slow-release component stops performing the purification operation when a termination condition is met. Simultaneously with the activation of the electric valves on both sides of the slow-release component, the refrigerator controller starts a timing operation, comparing the timed duration with a preset duration. When the preset duration is reached, the termination condition is determined to be met.

[0040] In some embodiments, the sustained-release component has a small hole 2-10 mm deep, which can be either round or square, and the area of ​​the small hole is 25-30 mm². 2 .

[0041] In some embodiments, the flavored gel comprises, by weight, 2.0-5.0 parts resin, 1.0-6.0 parts wetting agent, 0.5-4.0 parts essential oil, 0.5-6.0 parts solubilizer, 0.2-0.8 parts thickener, 0.1-0.3 parts preservative, and 80-98 parts 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 selected from glycerin, butylene glycol, pentanediol, hexanediol, 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 lemon essential oil used in this application mainly comprises limonene, β-pinene, and γ-terpinene, all of which are carefully extracted from the peel. The essential oil extraction is mainly carried out by cold pressing, extracting from the lemon peel with an oil yield of approximately 0.3% to 0.5%. At the same time, essential oil can also be extracted from lemon leaves, with an oil yield of approximately 0.2% to 0.3%, using steam distillation.

[0046] The main components of the orange essential oil used in this application include limonene, linalool, terpinene, sapinene, and myrcene. These components give orange essential oil its unique aroma and medicinal value. Limonene is one of the main components of orange essential oil, possessing a fresh citrus scent. Linalool is an important aroma component, giving the essential oil its distinctive fragrance. Components such as terpinene and sapinene also have a significant impact on the chemical properties and odor of the essential oil.

[0047] In addition, orange essential oil contains other chemical components, such as octanal, decanal, and geraniol acetate, which together constitute the complex chemical structure of orange essential oil. These components not only affect the aroma of the essential oil but also determine its effects in different applications. For example, limonene and linalool are widely used in food flavorings, while pine resin and sapindus oil may have specific therapeutic effects. Orange essential oil can be extracted by pressing the peel of citrus fruits.

[0048] The mandarin essential oils used in this application include green mandarin oil, yellow mandarin oil, and red mandarin oil. Green mandarin oil is extracted from unripe mandarins and has a slightly astringent, even bitter, leafy aroma. Green mandarin oil is free of furanocoumarins and is not photosensitive.

[0049] Orange essential oil comes from the semi-ripe stage of oranges. It has a faint floral scent and is the only citrus essential oil with a floral aroma. Orange essential oil is photosensitive.

[0050] Mandarin orange essential oil is extracted from fully ripe mandarins and has a sweet, refreshing mandarin orange scent. When used in aromatherapy, it brings a warm, sun-like feeling. However, mandarin orange essential oil is also photosensitive.

[0051] The main components of the apple essential oil used in this application include esters, aldehydes, and other volatile compounds. Esters such as amyl acetate, amyl butyrate, and amyl valerate constitute a significant portion of the apple flavoring, typically exceeding 50%. Aldehydes such as citral and citronellol serve as auxiliary components, modifying the formulation of the apple flavoring. Furthermore, apple essential oil also contains alcohols, such as ethanol and phenethyl alcohol, which impart specific aromas and properties to the apple essential oil.

[0052] Esters are the main components in apple flavoring formulations, including amyl acetate, amyl butyrate, amyl valerate, and ethyl butyrate, typically accounting for more than 50%. Other components, such as aldehydes like citral and citronellal, act as auxiliary agents, modifying the apple flavoring formulation. Furthermore, alcohols such as ethanol and phenethyl alcohol also play important roles in apple flavorings.

[0053] This application specifies that the essential oil components are lemon essential oil, orange essential oil, and apple essential oil, enabling the fragrance gel for refrigerators to absorb and eliminate odor molecules in the air. Simultaneously, the fragrance gel can absorb and remove organic compounds from the air, such as odors or musty smells. The fragrance gel can also dissolve some oily or sticky odors, dispersing them in the air and reducing their concentration. Furthermore, it is effective against some strong or persistent odors, such as toxic gases released by pollutants or severe mold contamination.

[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 carboxymethyl cellulose, sodium hydroxyethyl cellulose, and sodium carboxymethyl cellulose.

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

[0056] In some embodiments, the method for preparing the fragrance gel is as follows: according to the weight ratio, the resin is added into a container, deionized water is added and heated to 85-95°C;

[0057] After complete dissolution, stir at 300-500 r / min for 10-15 min, add wetting agent, solubilizer, thickener and preservative and stir evenly, then cool to 45-60℃, add essential oil and continue to stir evenly to obtain fragrant gel.

[0058] In some embodiments, this application provides a production process for the flavored gelatin described above, including the following steps:

[0059] Step 1: According to the weight ratio, add the resin to the container, add deionized water and heat to 85-95℃;

[0060] Step 2: After complete dissolution, stir at 300-500 r / min for 10-15 min, add wetting agent, solubilizer, thickener and preservative and stir evenly, then cool to 45-60℃, add essential oil and continue to stir evenly to obtain fragrant gel.

[0061] Example 1

[0062] A fragrant gelatinous product, composed of the following ingredients in the indicated weight ratios:

[0063]

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

[0065] The flavored gelling agent for refrigerators provided in this application uses edible flavoring oils that meet food-grade requirements. The flavored gelling agent provided in this application may have an external protective component, which can be EPS foam, EPE foam, paper-based protective component, etc. The protective component has pre-drilled small holes 2-10mm deep; these holes can be round, square, or other shapes, with an area of ​​25mm². 2 When using, place 0.05-0.2g of the scented gel in the designated area of ​​the refrigerator's interior protective panel.

[0066] This application controls the fragrance release rate by adjusting the pore size, while simultaneously preventing the fragrance gel from penetrating into the refrigerator's internal plastic and causing contamination. The fragrance gel provided in this application for refrigerators has a fast adsorption rate, is not easily saturated, and can completely adsorb odors inside the refrigerator, thus purifying the refrigerator's odor.

[0067] In some embodiments, this application also provides a purification device for performing the above-described method for purifying refrigerator odors. The provided purification device for refrigerator includes a housing, an odor sensor, a slow-release component, and a controller. The housing is provided with an odor sensor and a slow-release component, and the slow-release component stores the fragrance gel for refrigerator described in the above embodiments. The controller is used to obtain the concentration of odor molecules in a target area inside the refrigerator based on the odor sensor. When the concentration of the target odor molecules is greater than or equal to a preset concentration value, the controller controls the slow-release component to release purified gas.

[0068] By placing a purification device inside the refrigerator, the odor sensor monitors odor molecules in the target area in real time and detects the concentration of 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 purification efficiency of the refrigerator. Odors are less likely to regenerate after removal, thus improving the user experience.

[0069] In some embodiments, the odor sensor in the refrigerator's purification device detects odor gases in the food storage area. Once the odor sensor detects an odor gas, it sends a signal. The controller receives this signal and controls the slow-release component to operate. This odor sensor is a reducing sensor; it works by combining a chemically adsorbed substance in the sensor with a reducing gas, causing the odor sensor to be reduced and detect the odor gas, thus sending a signal to the controller. Specifically, in some embodiments, the odor sensor is configured as a metal oxide sensor whose resistance can be changed by reduction, releasing a reducing gas (organic polymer gas). When this reducing gas passes by, it captures oxygen atoms on the odor sensor, thereby changing the sensor's resistance and enabling odor detection.

[0070] The purification device for refrigerators provided in this application uses an odor sensor to detect odor gases in the food storage area. Once the odor sensor detects an odor gas, it sends a signal. A controller receives the signal from the odor sensor and controls a slow-release component to operate. During operation, the odor sensor detects the presence of odor gases in the food storage area. Upon detection, it sends a signal to the controller, which then controls the slow-release component to release purifying gases to purify the food storage area until no odor gases remain. This setup achieves purification of the refrigerator's interior, improving its safety during use.

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

[0072] Similar parts between the embodiments provided in this application can be referred to mutually. The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods extended from the solution of this application without creative effort shall fall within the scope of protection of this application.
