[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 deodorant and a deodorizing device for refrigerators. The deodorant for refrigerators provided by the present application uses edible volatile flavors that meet food grade requirements. The present application is packaged in plastic bags with small holes. On the one hand, the fragrance release rate is controlled by the size of the pores, and at the same time, the fragrance is blocked from penetrating into the plastic inside the refrigerator to cause pollution. The adhesive used in the present application is an odorless, formaldehyde-free, environmentally friendly adhesive that does not add additional odor and meets environmental protection requirements. The deodorant for refrigerators provided by the present application has a fast adsorption rate, is not easily saturated, and can completely absorb odors in the refrigerator.

[0030] In some embodiments, Figure 1 and Figure 2 As shown, the present application provides a deodorant for a refrigerator, the deodorant comprising:

[0031] A fragrance sustained-release substrate 1, wherein the fragrance sustained-release substrate 1 is composed of absorbent paper 2 and cardboard 3; the absorbent paper 2 and cardboard 3 are connected by an adhesive 4, the absorbent paper 2 absorbs volatile essence 5, and the fragrance sustained-release substrate 1 is arranged in a ventilated plastic bag 6; the volatile essence 5 includes at least one of triacetin, sweet orange extract, methyl jasmonate, grapefruit oil, α-hexylcinnamaldehyde, linalool, and benzyl salicylate.

[0032] In some embodiments, the volatile flavor 5 contains the following weight percentages: 45%-50% triacetin, 35%-40% sweet orange extract, 10%-15% methyl jasmonate, 2%-3% grapefruit oil, 2%-3% α-hexylcinnamaldehyde, 1%-2% linalool, and 1%-2% benzyl salicylate.

[0033] Sweet orange extract is a mixture of natural compounds extracted from the peel of sweet oranges. Its main components are limonene and limonol, and it also contains some other volatile organic compounds. The substance is specifically manifested as an orange-yellow liquid with a sweet orange fruit aroma. It is miscible with anhydrous ethanol, soluble in glacial acetic acid (1:1) and ethanol (1:2), and difficult to dissolve in water. The chemical formula of sweet orange extract is C 15 H 22 O, molecular weight is 218.33, density is 0.84g / mLat 25℃(lit.), and refractive index is n20 / D1.472(lit.). It has a strong ability to scavenge superoxide free radicals and can significantly inhibit membrane lipid peroxidation and membrane protein oxidative cross-linking.

[0034] Methyl jasmonate, chemical name is trans-3-oxo-2-(cis-2-pentenyl)-cyclopentaneacetic acid methyl ester, its chemical formula is C 14 H 12 O3, molecular weight 228.24g / mol. It is an aromatic compound with a persistent floral aroma and is often used as an ingredient in perfumes, food and drug additives, and cosmetics industries. Methyl jasmonate has a strong sweet scent of jasmine and can be used as a flavor additive. Methyl jasmonate has good stability and is soluble in most organic solvents, such as alcohols and ethers. It has a low boiling point and flash point, which makes it volatile. Methyl jasmonate is liquid at room temperature and is colorless or slightly yellow.

[0035] Grapefruit oil is a natural essential oil extracted from grapefruit (grapefruit) peel, which inherits the fresh aroma and multiple biologically active ingredients of grapefruit. The main components of grapefruit oil include d-limonene, α-pinene, β-pinene, myrcene, sabinene, octanal, nonanal, decanal, neral, β-caryophyllene and oleic acid ketone. These ingredients give grapefruit oil a unique aroma and multiple biological activities. Grapefruit oil has a fresh and sweet aroma with the typical characteristics of citrus fruits. At the same time, it also has a certain volatility, which can quickly emit fragrance and bring a fresh atmosphere to the environment.

[0036] The present application limits the components of volatile flavors to triacetin, sweet orange extract, methyl jasmonate, grapefruit oil, α-hexyl cinnamaldehyde, linalool, and benzyl salicylate, so that the deodorant used in the refrigerator can absorb and eliminate odor molecules in the air; at the same time, the deodorant can absorb and remove organic compounds in the air, such as odor or mold. The deodorant can also dissolve some oily or sticky odors, disperse them in the air, and reduce the concentration of odors. In addition, for some relatively strong or persistent odors, such as toxic gases released by pollutants or severe mold pollution, the deodorant can also...

[0037] In some embodiments, the thickness of the flavor sustained-release substrate 1 is 1-3 cm. By limiting the thickness of the flavor sustained-release substrate 1, it is possible to avoid the thickness of the substrate being too thick so that the volatile flavor 5 can be volatilized smoothly, and to avoid the thickness of the substrate being too thin so that the volatile flavor 5 can be completely volatilized, thereby affecting the adsorption efficiency.

[0038] In some embodiments, the cellulose fibers inside the absorbent paper 2 are interwoven to form a mesh structure, which contains a large number of tiny pores. The absorbent paper is a special paper product specially designed to efficiently absorb and lock in moisture. The main component of the absorbent paper is cellulose, which is a natural organic polymer compound. The cellulose in the paper is interwoven to form a mesh with many gaps. These gaps can hold moisture, which is also the so-called capillary effect. The cellulose fibers inside the paper are interwoven to form a mesh structure, which contains a large number of tiny pores.

[0039] In some embodiments, the cardboard 3 is a white cardboard made of high-quality wood pulp, which is calendered or embossed, and has a specific design pattern printed on the surface. The cardboard is a thick, firm, pure, high-quality wood pulp white cardboard.

[0040] In some embodiments, the adhesive 4 is a formaldehyde-free environmentally friendly adhesive, containing the following weight percentages: 55%-65% water, 4%-8% polyvinyl alcohol, 30%-40% polyvinyl acetate, 0%-0.5% vinyl acetate. The adhesive used is an odorless, formaldehyde-free environmentally friendly adhesive that does not add additional odor.

[0041] In some embodiments, the absorbent paper 2 first absorbs the volatile essence 5 and then adheres to the cardboard through the adhesive 4 .

[0042] The absorbent paper 2 first absorbs volatile essence 5 diluted with water by 20%-40%, and then is naturally dried for a period of time or passed through a hot drying tunnel, and then is bonded to the cardboard 3 through the adhesive 4.

[0043] In some embodiments, the air-permeable plastic bag 6 is made of one of high-density polyethylene HDPE, low-density polyethylene LDPE, and thermoplastic polyurethane TPU.

[0044] The volatile flavor in the refrigerator deodorant provided by the present application is an edible flavor that meets food grade requirements. The flavor release rate is controlled by the aperture size set on the vent plastic bag in the form of a combination of a flavor sustained-release substrate and a vent plastic bag. The vent plastic bag is waterproof, anti-fouling and moisture-proof, and can prevent the penetration of flavors. In the production process of the refrigerator deodorant, the film material has good bonding and high adhesion to the HIPS substrate through in-mold co-extrusion.

[0045] In some embodiments, the deodorant has an adhesive on the back side so as to be attached to a bottle frame, a drawer, or a glass shelf inside a refrigerator.

[0046] In some embodiments, the present application provides a production process for the deodorant for refrigerators in the above embodiments, comprising the following steps:

[0047] Step 1: Cut the absorbent paper into a designed shape, absorb a certain amount of volatile essence, and then dry it or volatilize the excess essence through a hot drying tunnel;

[0048] Step 2: Print the designed drawing on the surface of the cardboard, cut it into the designed shape, and connect it with the absorbent paper through adhesive;

[0049] Step 3: Place the connected flavor sustained-release tablets into a perforated packaging bag and seal it.

[0050] The deodorant for refrigerators provided in the present application uses edible volatile flavors that meet food grade requirements. The present application is packaged in plastic bags with small holes. On the one hand, the release rate of the fragrance is controlled by the size of the pores, and at the same time, the flavor is blocked from penetrating into the plastic inside the refrigerator to cause pollution. The adhesive used in the present application is an odorless, formaldehyde-free, environmentally friendly adhesive that does not add additional odor and meets environmental protection requirements. The deodorant for refrigerators provided in the present application has a fast adsorption rate, is not easily saturated, and can completely absorb odors in the refrigerator.

[0051] In some embodiments, the present application provides a deodorizing device for a refrigerator, the device comprising:

[0052] A box body, wherein an odor sensor, a slow-release component and a controller are arranged in the box body;

[0053] Odor sensor, used to detect the concentration of odor molecules in the target area of ​​the refrigerator;

[0054] A slow-release component, wherein the slow-release component comprises the deodorant for a refrigerator according to the first aspect;

[0055] The controller is used to control the slow-release component to release the deodorizing gas when the concentration of the odor molecules is greater than or equal to a preset concentration value.

[0056] The deodorizing device for a refrigerator provided in the present application comprises 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 a deodorizing material, i.e., the deodorant for the refrigerator in the above-mentioned embodiment; the controller is used to obtain the concentration of odor molecules in a target area in the refrigerator according to the odor sensor, and when the concentration of the target odor molecules is greater than or equal to a preset concentration value, the slow-release component is controlled to release the deodorizing gas.

[0057] By placing the deodorizing device for refrigerators in 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 deodorizing gas, thereby improving the efficiency of deodorizing the refrigerator. After the odor is removed, it is not easy to breed, thereby improving the user experience.

[0058] In some embodiments, the odor sensor in the deodorization 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 device 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. After that, the reducing gas (organic polymer gas) is released. 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.

[0059] The deodorizing 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 and release the deodorizing gas to deodorize the food storage area until there is no odorous gas in the food storage area. The above-mentioned setting can realize the deodorization treatment in the refrigerator and improve the safety of refrigerator use.

[0060] As can be seen from the above embodiments, the present application provides a deodorant and deodorant device for refrigerators, the deodorant comprising: a fragrance sustained-release substrate, the fragrance sustained-release substrate is composed of absorbent paper and cardboard; the absorbent paper and cardboard are connected by an adhesive, the absorbent paper absorbs volatile essence, and the fragrance sustained-release substrate is arranged in a ventilated plastic bag; the volatile essence comprises: at least one of triacetin, sweet orange extract, methyl jasmonate, grapefruit oil, α-hexyl cinnamaldehyde, linalool, and benzyl salicylate.
