[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0037] During long-term use, refrigerators, freezers and other refrigeration equipment store a variety of food. The smell of different foods and the amine and sulfur-containing gas components emitted after corruption make the equipment smell heavy, which seriously affects the user experience. Therefore, various deodorization technologies have emerged.

[0038] In the prior art, an activated carbon adsorption module or a sepiolite deodorization filter module is placed in the air flow channel of the refrigerator to sterilize and deodorize the air flow passing through. Since the deodorization module is placed in the air flow channel of the refrigerator, it can only sterilize and deodorize the air flow passing through the surface, achieving local deodorization, and cannot completely remove the odor.

[0039] The present application arranges zirconium oxide nano bubble stones in multiple filter chambers and combines them with an air circulation system, so that air can be fully filled into the filter chambers and fully react with the deodorizing liquid, thereby removing odors comprehensively and quickly.

[0040] Combination Figures 1 to 4 As shown, the embodiment of the present disclosure provides a deodorizing component 10 for a refrigerator 20 and the refrigerator 20. The deodorizing component 10 for the refrigerator 20 includes a first filter chamber 11, a second filter chamber 12, a plurality of zirconium oxide nano bubble stones 13 and an air circulation system 14. The first filter chamber 11 includes a first deodorizing solution 111; the second filter chamber 12 includes a second deodorizing solution 121; the plurality of zirconium oxide nano bubble stones 13 are immersed in the first deodorizing solution 111 and the second deodorizing solution 121 respectively; the air circulation system 14 is used to control the circulation of air between the refrigeration space 211 and the first deodorizing solution 111 and the second deodorizing solution 121.

[0041] like Figures 1 to 4 As shown, a first deodorizing solution 111 is provided in the first filter chamber 11, wherein the volume of the first deodorizing solution 111 occupies part of the volume of the first filter chamber 11, so that a certain space is left on the upper part of the first filter chamber 11 for accommodating air. Similarly, a second deodorizing solution 121 is provided in the second filter chamber 12, wherein the volume of the second deodorizing solution 121 occupies part of the volume of the second filter chamber 12, so that a certain space is left on the upper part of the second filter chamber 12 for accommodating air. There are a plurality of zirconium oxide nano bubble stones 13, which correspond to the first filter chamber 11 and the second filter chamber 12, respectively, and are provided at the bottom of the first filter chamber 11 and the second filter chamber 12, covering the bottom of the first filter chamber 11 and the second filter chamber 12, and correspondingly immersed in the first deodorizing solution 111 and the second deodorizing solution 121. The air circulation system 14 is connected to the refrigeration space 211, the first deodorizing solution 111 and the second deodorizing solution 121 respectively, so as to cause the air in the refrigeration space 211 to sequentially enter the first deodorizing solution 111 and the second deodorizing solution 121 for filtering in sequence to deodorize.

[0042] Optionally, the air circulation system 14 includes a circulation pipeline 141 and an air pump 142. The circulation pipeline 141 sequentially connects the refrigeration space 211, the first filter chamber 11 and the second filter chamber 12; the air pump 142 is connected to one end of the circulation pipeline 141 to drive the air circulation between the refrigeration space 211 and the first filter chamber 11 and the second filter chamber 12.

[0043] like Figures 1 to 4 As shown, the circulation pipeline 141 connects the first filter chamber 11 and the second filter chamber 12 in series with the refrigeration space 211. The air pump 142 is connected to one end of the circulation pipeline 141 to sequentially fill the air in the refrigeration space 211 with the first deodorizing solution 111 and the second deodorizing solution 121 and then discharge it into the refrigeration space 211, so as to filter and deodorize the air in the refrigeration space 211 with the first deodorizing solution 111 and the second deodorizing solution 121.

[0044] Optionally, the volume of the first deodorizing solution 111 accounts for 40% to 70% of the volume of the first filter chamber 11 ; the volume of the second deodorizing solution 121 accounts for 40% to 70% of the volume of the second filter chamber 12 .

[0045] like Figure 1 , Figure 2 and Figure 4As shown, the first deodorizing solution 111 and the second deodorizing solution 121 are installed in the lower part of the cavity space of the first filter cavity 11 and the second filter cavity 12, and a certain space is reserved in the upper part for accommodating air. The volume of the first deodorizing solution 111 accounts for 40% to 70% of the volume of the first filter cavity 11; the amount of the first deodorizing solution 111 will not be too small, so that the gas filled with the first deodorizing solution 111 stays in the first deodorizing solution 111 for too short a time and cannot react completely, or the first deodorizing solution 111 is replaced too frequently. At the same time, the amount of the first deodorizing solution 111 will not be too much, so as not to cause the space volume of the upper part of the first filter cavity 11 to be too small to accommodate air, resulting in liquid flowing into the circulation pipeline. Similarly, the volume of the second deodorizing solution 121 accounts for 40% to 70% of the volume of the second filter cavity 12. The first filter chamber 11 and the second filter chamber 12 are connected in series through a circulation pipeline 141. The first filter chamber 11 includes a first inlet 112 and a first outlet 113. The first inlet 112 is connected to the circulation pipeline 141. One end of the circulation pipeline 141 is located outside the first inlet 112 and the other end passes through the first inlet 112 to the first deodorizing solution 111 of the first filter chamber 11, so that air enters the first deodorizing solution 111 from the first inlet 112, and the air filtered by the first deodorizing solution 111 rises to the upper part of the first filter chamber 11 and flows out from the circulation pipeline 141 at the first outlet 113, flows into the second deodorizing solution 121 from the second inlet 122 along the circulation pipeline 141, rises to the upper part of the second filter chamber 12 after being filtered by the second deodorizing solution 121, flows out from the circulation pipeline 141 at the second outlet 123, flows into the air pump 142 from the third inlet 1421, and is finally discharged into the refrigeration space 211 from the third outlet 1422 of the air pump 142. The air pump 142 is connected to a control device to control the working state of the air pump 142 .

[0046] Optionally, the circulation pipeline 141 includes a first pipeline 1411, a second pipeline 1412, a third pipeline 1413 and a fourth pipeline 1414. The first pipeline 1411 connects the refrigeration space 211 with the lower part of the first deodorized solution 111 in the first filter chamber 11; the second pipeline 1412 connects the space above the liquid surface of the first deodorized solution 111 in the first filter chamber 11 with the lower part of the second deodorized solution 121 in the second filter chamber 12; the third pipeline 1413 connects the space above the liquid surface of the second deodorized solution 121 in the second filter chamber 12 with the inlet of the air pump 142; and the fourth pipeline 1414 connects the outlet of the air pump 142 with the refrigeration space 211.

[0047] like Figure 2 and Figure 4As shown, the first pipeline 1411 connects the refrigeration space 211 and the first inlet 112 of the first filter chamber 11, and one end of the first pipeline 1411 is embedded in the first deodorizing solution 111 to the zirconia nano bubble stone 13, so that the air entering the first filter chamber 11 through the first pipeline 1411 can contact the zirconia nano bubble stone 13 at the first time, and the gas is dispersed into small bubbles with a diameter of 1 to 3 mm by the nano zirconia bubble stone and enters the first deodorizing solution 111, fully absorbing the odorous gas. So that the air can contact the first deodorizing solution 111 more comprehensively, react more fully, and deodorize more comprehensively and thoroughly. After the first deodorizing solution 111 reacts completely, the air rises from the liquid level of the first deodorizing solution 111 to the upper space of the first filter chamber 11, and flows into the second deodorizing solution 121 in the second filter chamber 12 through the second pipe 1412. One end of the second pipe 1412 goes deep into the bottom of the second deodorizing solution 121 to the zirconium oxide nano bubble stone 13 under the second deodorizing solution 121, and disperses into a plurality of small bubbles with a diameter of 1 to 3 mm, and enters the second deodorizing solution 121, fully absorbing the odorous gas. After the reaction is complete, the air flows into the air pump 142 through the third pipe 1413, and the air pump 142 discharges the deodorized air through the fourth pipe 1414 into the refrigeration space 211.

[0048] Optionally, the zirconia nano bubble stone 13 is laid at the bottom of the first filter chamber 11 and the bottom of the second filter chamber 12, respectively, so that the upper surface of the zirconia nano bubble stone 13 is fully in contact with the first deodorizing solution 111 and the second deodorizing solution 121, respectively.

[0049] like Figure 4 As shown, the zirconia nano bubble stones 13 are respectively immersed in the bottom of the first deodorizing solution 111 and the bottom of the second deodorizing solution 121. The first deodorizing solution 111 and the second deodorizing solution 121 are arranged above the corresponding zirconia nano bubble stones 13. When air enters the bottom of the first deodorizing solution 111 or the second deodorizing solution 121, it can quickly contact with the corresponding zirconia nano bubble stones 13 and disperse into a plurality of small bubbles. The small bubbles gradually rise from the bottom of the first deodorizing solution 111 or the second deodorizing solution 121. In this process, they can fully contact with the first deodorizing solution 111 and the second deodorizing solution 121 to make the reaction sufficient.

[0050] In some embodiments, the upper surface of the zirconium oxide nano bubble stone 13 is non-planar.

[0051] Exemplarily, the upper surface of the zirconia nano-bubble stone 13 is uneven, which can increase the contact area between the bubbles and the zirconia nano-bubble stone 13 to disperse the bubbles into multiple bubbles.

[0052] Optionally, the first filter cavity 11 and / or the second filter cavity 12 is a transparent cavity; the deodorizing assembly 10 for the refrigerator 20 further includes a first color changing agent, a second color changing agent and a colorimetric glass plate 15. The first color changing agent is disposed in the first deodorizing solution 111; the second color changing agent is disposed in the second deodorizing solution 121; the first color changing agent and the second color changing agent change color correspondingly with the change of the pH value of the first deodorizing solution 111 and the second deodorizing solution 121; the colorimetric glass plate 15 is disposed in the first filter cavity 11 and the second filter cavity 12, respectively, for correspondingly indicating the deodorizing effect of the first deodorizing solution 111 and the second deodorizing solution 121.

[0053] like Figure 1 and Figure 2 As shown, the first filter chamber 11 and / or the second filter chamber 12 is a transparent chamber, so that the color change of the first deodorizing solution 111 and the second deodorizing solution 121 can be seen by naked eyes. The first color-changing agent and the colorimetric glass plate 15 are arranged in the first filter chamber 11, and the second color-changing agent and the colorimetric glass plate 15 are arranged in the second filter chamber 12. The color of the first deodorizing solution 111 and the second deodorizing solution 121 and the colorimetric glass plate 15 can be compared with the naked eyes to determine the deodorizing condition and deodorizing effect of the first deodorizing solution 111 and the second deodorizing solution 121. When the first deodorizing solution 111 or the second deodorizing solution 121 no longer changes color during the deodorizing process, it indicates failure.

[0054] In some embodiments, the first deodorizing solution 111 includes an acidic deodorant and a first color-changing agent. The second deodorizing solution 121 includes an alkaline deodorant and a second color-changing agent. The air circulation system 14 first fills the air into the first deodorizing solution 111 of the first filter chamber 11, and the acidic deodorant in the first deodorizing solution 111 can react with the alkaline odor in the air to adsorb and remove the odor. The air circulation system 14 then fills the air filtered from the first filter chamber 11 into the second deodorizing solution 121 of the second filter chamber 12, and the alkaline deodorant in the second deodorizing solution 121 reacts with the acidic odor in the air to adsorb and remove the odor. There is a first color-changing agent in the acidic deodorant, and the acidic deodorant reacts with the alkaline substance in the odor to reduce the acidity to eliminate it. In this process, the color of the first color-changing agent changes with the acidity of the solution to show the amount of acidic odor in the air. The alkaline deodorant reacts with the acidic substance in the odor to reduce the alkalinity to eliminate it. During this process, the color of the second color-changing agent changes with the alkalinity of the solution to show the amount of alkaline odor in the ventilation. When the concentration of acid and alkaline odor in the air is very high, the first deodorizing solution 111 and the second deodorizing solution 121 change color faster and the color difference gradient is larger, which indicates that the food is seriously corrupted and it is necessary to check and clean up the seriously corrupted food in time to reduce the impact on the uncorrupted food. When the concentration of acid and alkaline odor in the air is very low, the first deodorizing solution 111 and the second deodorizing solution 121 change color slowly and the color gradient is small, so there is no need to find corrupted food. Therefore, by judging the color change of the first deodorizing solution 111 and the second deodorizing solution 121, the concentration of corrupt gas in the refrigeration space 211 is judged to detect the freshness of the food. When the first deodorizer or the second deodorizer absorbs the odor but the color no longer changes, it is prompted that the corresponding deodorizer is invalid and the corresponding deodorizer is replaced in time.

[0055] In some embodiments, the first deodorizing solution 111 includes glycerin, sodium chloride, boric acid, bromocresol green, methyl red, water and ethanol; the second deodorizing solution 121 includes glycerin, sodium chloride, sodium hydroxide, methylene blue, malachite green, methyl red, water and ethanol.

[0056] During the storage process of fruits and vegetables in the refrigerator 20, when the freshness decreases and they begin to rot, they are accompanied by the generation of acetic acid, ethanol, hydrogen sulfide and other odorous gases; meat, milk, eggs and seafood mainly produce amines, ammonia, hydrogen sulfide and other odorous gases during the rot process. The disclosed embodiment utilizes the principles of acid-base neutralization and like dissolves like, and achieves the purpose of removing the main odorous gases produced during the food spoilage process by improving the adsorption structure and the formula of the adsorbent. The mixed solution of bromocresol green and methyl red is wine red under acidic conditions, and turns to blue-green under alkaline conditions, and the blue-green color becomes deeper and deeper as the alkalinity increases; the mixed solution of methylene blue, malachite green and methyl red is blue-purple under alkaline conditions, and gradually turns to blue and green under the condition of gradually increasing acidity. Malachite green shows green under lower pH conditions, which increases the gradient range of the mixed solution of methylene blue and methyl red in the green zone.

[0057] In this embodiment, boric acid is an acidic substance that can undergo an acid-base neutralization reaction with alkaline odors to absorb odors in the air. In addition, boric acid in the deodorant makes the deodorant acidic, and the mixed solution of bromocresol green and methyl red is wine red. As the boric acid continues to react with the alkaline odor, the deodorant gradually changes from acidic to alkaline, and the mixed solution of bromocresol green and methyl red gradually changes from wine red to blue-green. After the boric acid in the deodorant is completely reacted, the acidity and alkalinity of the deodorant no longer change, and the color of the deodorant no longer changes. Similarly, in this embodiment, sodium hydroxide is an alkaline substance, which can undergo an acid-base neutralization reaction with acidic odors to absorb odors in the air, and sodium hydroxide in the deodorant makes the deodorant alkaline, and a 1.0 g / L mixed solution of methylene blue, malachite green and methyl red is bluish purple. As sodium hydroxide continues to react with acidic odors, the deodorant gradually changes from alkaline to acidic, and a 1.0 g / L mixed solution of methylene blue, malachite green and methyl red gradually changes from bluish purple to blue and green. After the sodium hydroxide in the deodorant is completely reacted, the acidity and alkalinity of the deodorant no longer changes, and the color of the deodorant no longer changes.

[0058] In some embodiments, the first deodorant is prepared by the following raw materials: 60g glycerol, 10g sodium chloride, 12g boric acid, 0.8mg bromocresol green, 0.16mg methyl red, 17.0g water, and 2g ethanol.

[0065] like Figure 3 As shown, the first pipeline 1411 of the circulation pipeline 141 is the air inlet of the circulation system, and the fourth pipeline 1414 is the air outlet of the circulation system. One end of the first pipeline 1411 extends downward to the bottom corner of the rear wall of the refrigerator 20, so that the air in the refrigeration space 211 enters the first pipeline 1411 from the bottom corner of the rear wall for deodorization circulation. One end of the fourth pipeline 1414 extends upward to the upper corner of the rear wall and forms the diagonal line of the rear wall of the refrigeration space 211 with the bottom corner of the first pipeline 1411. The filtered air is discharged to the upper corner of the refrigeration space 211. In this way, the air in the refrigeration space 211 can be circulated comprehensively, preventing only the air in a local space from being circulated locally, and can be deodorized more comprehensively.

[0066] Optionally, the deodorizing assembly 10 further includes a color sensor 16 and a failure alarm. The color sensor 16 is disposed on the front side wall of the refrigeration space 211 opposite to the first deodorizing solution 111 and the second deodorizing solution 121 respectively; the failure alarm is disposed on the housing 21 corresponding to the color sensor 16, and is used to issue an alarm when the first deodorizing solution 111 and / or the second deodorizing solution 121 fails in deodorizing, so as to prompt the replacement of the corresponding deodorizing solution.

[0067] like Figure 1 and Figure 3 As shown, the color sensor 16 corresponds to the first deodorizing solution 111 and the second deodorizing solution 121 one by one, so as to accurately identify the color of the first deodorizing solution 111 and the second deodorizing solution 121. The failure alarm and the color sensor 16 are connected to the control center, and the control center determines whether the first deodorizing solution 111 and the second deodorizing solution 121 have deodorizing effect by analyzing the information of the color sensor 16. When the first deodorizing solution 111 and the second deodorizing solution 121 no longer change color during the deodorizing process, the color sensor 16 transmits the information to the control center, and the control center controls the failure alarm to issue a failure alarm to prompt the replacement of the deodorizing solution.

[0071] The control system controls the failure alarm by analyzing the color sensor 16 , and determines whether the deodorization function needs to be turned on based on the information from the odor sensor 22 , so as to control the working state of the air pump 142 .

[0072] It can be understood that the deodorizing assembly 10 provided by the present invention can also be applied to other refrigeration equipment and / or temperature control equipment, including but not limited to: refrigerators and air conditioners.
