Description

Technical Field

[0001] The present application relates to the technical field of kitchen cleaning, and in particular to a kitchen oil stain cleaning agent and a range hood cleaning method. Background Art

[0002] The kitchen is one of the most frequently used places in family life. However, due to frequent cooking and the influence of oil smoke, the kitchen range hood is prone to accumulate a lot of oil stains. If the range hood is not cleaned for a long time, the oil stains will accumulate over time. A large amount of oil stains attached to the range hood will increase the turbine load, making the range hood more laborious to operate, and the smoke exhaust is not smooth, causing the oil smoke to spread widely in the room. Excessive inhalation can lead to chronic pharyngitis, tracheitis and other respiratory diseases, and even have the risk of cancer. The components of kitchen oil stains mainly include high-temperature grease, cross-linked resin, coked grease, dust and microorganisms, which are more difficult to dissolve and clean than ordinary oil stains.

[0003] In order to solve the above-mentioned problem, a steam range hood cleaning machine has been developed. The range hood has a built-in steam generator, so that the high-temperature and high-pressure steam generated by the steam generator can be used to clean the turbine, volute and filter inside the range hood. However, since the steam itself does not have the ability to decompose oil stains, the above-mentioned range hood cannot clean certain stubborn stains remaining on the turbine, volute and filter, resulting in incomplete cleaning.

[0004] Moreover, in daily life, the cleaning agents used for cleaning range hoods are mostly detergents, washing powders, etc., which have poor cleaning effects, high cleaning costs, great damage to range hood equipment, and certain harm to human body and environment. Existing kitchen oil cleaning agents specially used for cleaning kitchen oil stains have problems such as relatively mild cleaning effects and unsatisfactory effects in removing heavy dirt, and cannot achieve good cleaning effects. Summary of the invention

[0005] The purpose of the present application is to provide a kitchen grease cleaning agent, which has the advantage of good kitchen grease cleaning effect.

[0006] Another object of the present application is to provide a range hood cleaning method, which can be used in conjunction with a kitchen oil stain cleaning agent to fully clean the range hood.

[0007] To solve the above problems, the technical method adopted by the present invention is:

[0008] On the one hand, an embodiment of the present application provides a kitchen oil cleaning agent, comprising the following raw materials in parts by weight: 30-50 parts of sodium silicate, 1-10 parts of sodium gluconate, 1-10 parts of sodium α-olefin sulfonate, 1-10 parts of disodium diaminetetraacetic acid, 1-10 parts of sodium carbonate and 1-10 parts of sodium hydroxide.

[0009] On the other hand, an embodiment of the present application provides a range hood cleaning method, comprising the following steps:

[0010] Dilute the kitchen grease cleaner into water to obtain a soaking solution;

[0011] Remove the oil cup, oil net and decorative cover of the range hood, separate the exhaust pipe from the connection end of the range hood, remove the range hood, and then remove the panel, turbine, non-return valve and electrical connection wires of the range hood, pour out the oil stains in the oil cup, put the oil cup, oil net, turbine and non-return valve into the soaking liquid, soak them, clean the soaked oil cup, oil net, turbine and non-return valve, and then clean the oil cup, oil net, panel, turbine and non-return valve with clean water;

[0012] Dip a towel in the soaking liquid and wipe the stains on the decorative cover, panel, external smoke chamber and electrical connection wires. Then rinse the towel with clean water and wipe the oil stains on the decorative cover, panel, external smoke chamber and electrical connection wires.

[0013] Use high-temperature steam from a spray gun to clean and sterilize the oil cup, oil screen, decorative cover, air duct cover, panel, turbine, check valve and external smoke chamber;

[0014] Install the cleaned oil cup, oil screen, decorative cover, panel, turbine, check valve, external smoke chamber and electrical connections back into the range hood. Finally, connect the exhaust pipe to the range hood to complete the cleaning work.

[0015] Compared with the prior art, the invention of this application has at least the following advantages or beneficial effects:

[0016] The kitchen oil stain cleaning agent of the present application has strong degreasing ability, has relatively good stripping ability for stains and oil stains attached to the surface of stainless steel, and is harmless to the human body. The present application adds sodium gluconate, which is non-toxic and can form chelates with metal ions. After biochemical treatment, it can quickly and completely degrade oil stains and has relatively good stripping ability for stains and oil stains attached to the surface of stainless steel. At the same time, sodium silicate, sodium gluconate and disodium diaminetetraacetic acid have strong chelating effects with metal ions. The three are used in combination and synergistically, which enhances the biodegradability of the kitchen oil stain cleaning agent. Sodium carbonate and sodium hydroxide have the effect of enhancing washing, especially for grease stains. It has a good cleaning effect. The added sodium α-olefin sulfonate is an anionic surfactant, which has a good effect of promoting the dispersion of oil stains in water and accelerating the decomposition of oil stains.

[0017] The cleaning method of the present application is simple and can clean the range hood thoroughly, has a fast cleaning speed, saves time, and can thoroughly remove residual grease and bacteria in the range hood. Currently, most range hoods are installed in an embedded manner, which makes it impossible to completely disassemble the range hood for cleaning. The use of a cleaning agent, combined with nozzle steam treatment and sterilization treatment, can make up for the problem that traditional cleaning modes cannot fully clean the range hood (for example: turbine).

[0088] Experimental example

[0089] The kitchen oil cleaning agents of Example 1, Example 3, Example 5 and Comparative Examples 1-3 were used to conduct degreasing effect experiments and decontamination effect experiments.

[0090] Degreasing effect experiment: Take the same stainless steel plate and clean it with anhydrous ethanol, dry it and weigh it as M1, pour olive oil into the plate and soak it for 10 seconds, dry it for 30 minutes, wipe the unabsorbed oil on the plate with filter paper and weigh it again as M2, prepare the kitchen oil cleaning agent into a 0.5% solution 500mL in a 1L beaker, heat it in a water bath to between 30 and 37°C, put the plate in the beaker, stir it twice with a stick, then put the plate in a drying oven at 60°C to dry for 6 hours, cool the dried plate at room temperature, weigh it again and record it as M3, repeat each sample 3 times, take the average value as the final result, and the results are shown in Table 1. Calculate the degreasing rate according to the following formula:

[0091] Oil removal rate = (M2-M3) / (M2-M1)×100%

[0092] Decontamination effect experiment: The same stainless steel plate was cleaned with anhydrous ethanol, dried and weighed as M1, the stain (equal amounts of vegetable oil and lard accounted for 20%, wheat flour accounted for 15%, whole milk powder accounted for 10%, egg liquid accounted for 30%, and distilled water accounted for the rest) was poured into the plate and soaked for 10 seconds, dried for 30 minutes, and the unabsorbed oil on the plate was wiped with filter paper and weighed again as M2, the kitchen oil cleaning agent was prepared into a 0.5% solution of 500mL in a 1L beaker, heated to 30-37℃ in a water bath, the plate was placed in the beaker, stirred twice with a stick, and then the plate was placed in a drying oven at 60℃ for 6h, and the dried plate was cooled at room temperature, weighed again and recorded as M3, each sample was repeated 3 times, and the average value was taken as the final result, as shown in Table 1. The decontamination rate was calculated according to the oil removal rate formula.

[0093] Table 1

[0094] Sample Oil removal rate / % Decontamination rate / % Example 1 91.3 92.8 Example 3 98.5 98.9 Example 5 95.1 95.8 Comparative Example 1 83.5 90.8 Comparative Example 2 85.7 89.2 Comparative Example 3 83.9 90.1

[0095] By observing Table 1, it can be seen that the kitchen oil cleaning agent of Example 3 has the best degreasing effect and decontamination effect, and by comparing Example 3 with Comparative Examples 1-3, it can be seen that the combination of sodium silicate, sodium gluconate and disodium diaminetetraacetic acid has a good synergistic effect, which enhances the degreasing effect and decontamination effect.

[0096] In summary, the kitchen oil stain cleaning agent of the present application has a strong degreasing ability, has a relatively good stripping ability for stains and oil stains attached to the surface of stainless steel, and is harmless to the human body. The present application adds sodium gluconate, which is non-toxic and can form chelates with metal ions. After biochemical treatment, it can quickly and completely degrade oil stains and has a relatively good stripping ability for stains and oil stains attached to the surface of stainless steel. At the same time, sodium silicate, sodium gluconate and disodium diaminetetraacetic acid have a strong chelating effect with metal ions. The three are used in combination and synergistically, which enhances the biodegradability of the kitchen oil stain cleaning agent. Sodium carbonate and sodium hydroxide have an enhanced washing effect, especially for grease stains. It has a good cleaning effect. The added sodium α-olefin sulfonate is an anionic surfactant, which has a good effect of promoting the dispersion of oil stains in water and accelerating the decomposition of oil stains.

[0097] The cleaning method of the present application is simple and can clean the range hood thoroughly, has a fast cleaning speed, saves time, and can thoroughly remove residual grease and bacteria in the range hood. Currently, most range hoods are installed in an embedded manner, which makes it impossible to completely disassemble the range hood for cleaning. The use of a cleaning agent, combined with nozzle steam treatment and sterilization treatment, can make up for the problem that traditional cleaning modes cannot fully clean the range hood (for example: turbine).

[0098] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments.
