[0041] Embodiment 1

[0042] like Figures 1-5As shown in the figure, a remaining amount detection structure for a household appliance sterilization module includes a remaining amount indicating body 100. The household appliance sterilization module is a device capable of releasing disinfection substances inside a household appliance, and the household appliance can be a household appliance such as a refrigerator or a freezer for storing items and requiring a good storage environment. The remaining amount indicating body 100 is installed on the inner liner 200 of the household appliance box. Specifically, the remaining amount indicating body 100 can be installed at any position of the inner liner 200, such as being placed at the top of the inner liner 200 or provided on the side of the inner liner 200. The remaining amount indicating body 100 includes: a turbidity sensor 16, which is electrically connected to the plug-in terminal on the inner liner 200 of the household appliance box to detect the color change inside the household appliance sterilization module; a box body, including a containing space for containing the sterilization substance or the reaction raw material of the sterilization substance; an installation cavity for the turbidity sensor 16 is provided inside the box body, and at least part of the installation cavity is made of a transparent material; so that the turbidity sensor 16 detects the color change inside the box body through the transparent part of the installation cavity to sense the change in the remaining amount of the sterilization substance inside the household appliance sterilization module. In order not to affect the containing space inside the box body, the installation cavity can extend from the surface of the box body away from the inside of the box body. At this time, the turbidity sensor 16 is bonded or fixed to the installation cavity through other fixing structures; in some other embodiments, the installation cavity is recessed from the surface of the box body towards the inside of the box body so that the turbidity sensor 16 is surrounded by the sterilization substance; at this time, the installation cavity is inside the containing space of the box body. Although it occupies a certain space in the containing space, at this time, the turbidity sensor 16 is surrounded by the object to be detected in the containing space, which can improve the detection accuracy of the turbidity sensor 16; in addition, since the installation cavity is formed by being recessed towards the inside of the box body, the turbidity sensor 16 can be directly placed in the installation cavity for fixation without other fixing structures.

[0043] The box body can be directly integrally formed or assembled. When the box body is an assembled box body, the box body includes: a bottom cover 10, one side of the bottom cover 10 includes a first chamber 101 for accommodating the turbidity sensor 16, and the shape and size of the first chamber 101 can be set according to the turbidity sensor 16 so that the turbidity sensor 16 is stably accommodated on the bottom cover 10. At least the first chamber 101 is made of a transparent material; a top cover 12 for fixedly connecting with the bottom cover 10 and jointly forming a accommodating space for the sterilizing substance or the reaction raw material of the sterilizing substance. It should be noted that this accommodating space is directly used to accommodate the disinfection volatiles or before use, this accommodating space is used to store the raw materials for preparing the disinfection volatiles, and during use, this accommodating space is used to store the disinfection volatiles. In some embodiments, the bottom cover 10 can be ultrasonically welded to the top cover 12; in other embodiments, the bottom cover 10 and the top cover 12 can be fixed by means of snap connection, socket connection, screw connection, bonding, etc., that is, the fixed connection method between the top cover 12 and the bottom cover 10 includes detachable connection and non-detachable connection. When non-detachable connection is adopted, the airtightness of the margin indicating body 100 can be ensured. Specifically, when there are disinfection volatiles in the closed space, the turbidity sensor 16 indicates the remaining amount of the disinfection gas by detecting the color change in the accommodating space. When the volatile for sterilization in the accommodating space is chlorine dioxide gas, this chlorine dioxide gas needs to be loaded in a gel-like substance. At this time, the remaining amount of chlorine dioxide gas is obtained by detecting the color change of the gel in the accommodating space by the turbidity sensor 16; when the raw material for preparing the volatile is in the accommodating space, the remaining amount of the volatile is obtained by detecting the color change of the liquid or gel in the accommodating space by the turbidity sensor 16. This disinfection gas is preferably a green, environmentally friendly, and non-toxic disinfection gas, such as chlorine dioxide, ozone; when the disinfection gas starts to diffuse into the household electrical appliance box body, as the color fades, it indicates that the remaining amount of the disinfection gas is constantly changing. When the turbidity sensor 16 obtains that there is no color change, it means that the disinfection gas has been exhausted. Since the turbidity sensor 16 needs to accurately sense the color change, a disinfection gas with a more prominent color is preferably selected, such as chlorine dioxide gas which is yellow itself. There will be a more obvious color change in the accommodating space during its continuous diffusion into the household electrical appliance box body, which is convenient for the turbidity sensor 16 to obtain more accurate data to reflect the remaining amount of the disinfection gas.

[0044] For the convenience of processing, the bottom cover can be directly made of a transparent material to facilitate the detection by the turbidity sensor 16.

[0045] Before the home appliance sterilization module is used, the reactant is a colorless transparent liquid. When the home appliance sterilization module is activated, the reactants are mixed to form a colored liquid or gel in the home appliance sterilization module. As the volatile substances used for disinfection continue to evaporate, the color gradually fades. At this time, the turbidity sensor is used to detect the change in the color of the liquid or gel, and the data is transmitted to the main control board, so as to timely understand the remaining amount of volatile substances in the home appliance sterilization module in the home appliance box, facilitate timely replacement, and maintain a good storage environment in the home appliance box.

[0046] The disinfection volatiles in the enclosed space are finished products or disinfection volatiles prepared on-site in real time. The volatiles can be gases or gases loaded in liquids or gels. Specifically, the enclosed space can be used to directly store disinfection gas, but since the enclosed space is limited, the amount of disinfection gas that can be stored is limited. If this type of home appliance sterilization module is used, it needs to be replaced frequently in a short period of time; at this time, the disinfection gas can be chlorine dioxide or ozone. In order to obtain a home appliance sterilization module with a longer service life and improve user experience, the enclosed space can be used to store raw materials for preparing disinfection gas. When the home appliance sterilization module is needed, the raw materials for preparing disinfection gas are triggered to react to prepare a large amount of disinfection gas.

[0047] When the disinfecting gas is the disinfecting gas of the finished product, the top cover 12 and / or the bottom cover 10 also include a breathable area and a sealing layer (not shown), and the sealing layer is covered on the breathable area when the home appliance sterilization module is not activated. That is, if the disinfecting gas is the disinfecting gas of the finished product, the remaining indication body 100 is not breathable before it is activated, but after it is activated, a breathable area is required to allow the disinfecting gas to enter the home appliance box. Therefore, a number of vents can be set on the top cover 12 or the bottom cover 10, and then a sealing layer is covered on the several vents. The sealing layer can be opened or punctured before use, or the sealing layer is a cover body covered on the breathable part. When it is needed to use, the sealing layer can be disassembled. The vent can also be a breathable material, such as a breathable film. In some embodiments, a breathable area and a sealing layer can be set on both the top cover 12 and the bottom cover 10. At this time, after the sealing layer is broken, the circulation of the disinfecting gas and the gas in the home appliance box can be improved.

[0048] When the disinfection gas is prepared in real time on site, the remaining amount indicating body 100 includes at least two independent spaces for storing the reaction raw materials of the disinfection gas. In some embodiments, when chlorine dioxide gas is prepared on site, the remaining amount indicating body 100 includes two or more independent spaces for storing raw materials or other materials. For example, when there are two independent spaces, one space is used to store the first reactant and the other space is used to store the second reactant; for example, one space stores an acidic liquid, such as hypochlorous acid and / or hydrochloric acid, etc., and the second space stores a solid powder, which is generally a chlorate or chlorite powder; it should be understood that the acidic liquid can be arranged in the second space and the solid powder can be arranged in the first space. It should be understood that the substances stored in the first space and the second space can be any combination of substances that can generate chlorine dioxide, and the state of the substances is not limited, that is, it can be liquid or solid. For example, chlorine dioxide gas can be generated by reacting an acid solution with an aqueous solution of sodium chlorite. In some embodiments, the remaining amount indicating body 100 includes three independent spaces for storing the reaction raw materials of the disinfection gas. For example, in addition to the spaces for storing solid powder and acidic liquid, a space can be added for storing water, and the stored water can be used to dissolve the solid powder to facilitate the progress of the whole chemical reaction. In addition to storing the raw materials for preparing chlorine dioxide gas, a space can be added in the remaining amount indicating body 100 for storing a flavoring agent. When it is damaged, the flavoring agent can enter the household electrical appliance box body to add fragrance to the household electrical appliance box body.

[0049] It should be noted that when preparing the disinfection gas, the prepared disinfection gas is preferably chlorine dioxide; because ozone will produce precipitation during the chemical preparation process, and the precipitation will affect the detection accuracy of the turbidity sensor 16. Therefore, when the disinfection gas is involved in this embodiment, the disinfection gas refers to chlorine dioxide gas.

[0050] In some embodiments, in order to form two independent spaces in the remaining amount indicating body 100, the remaining amount indicating body 100 further includes a first box body 11. The first box body 11 divides the accommodating space into two independent chambers, which are respectively used to place a reactant; after the first box body 11 is subjected to an external force, a part of the first box body 11 is separated from the bottom cover 10 to mix the two reactants to generate a volatile substance for sterilization. For example, the first box body 11 is assembled between the top cover 12 and the bottom cover 10, and after the first box body is subjected to an external force, a part of the first box body 11 still remains connected to the first box body 11 or the bottom cover 10. For example, the first box body 11 is a flip structure arranged in the accommodating space formed by the top cover 12 and the bottom cover 10. After the first box body 11 is subjected to an external force, a part of the first box body 11 is separated from the accommodating space to facilitate the mixing of the reactants; at this time, the sealing performance of the first box body is general.

[0051] In order to further improve the sealing performance of a box body including at least two independent chambers before activation, in some embodiments, the other side of the bottom cover 10 (the side where the first chamber 101 is located is one side of the bottom cover 10) further includes a second chamber 103, which forms a containing space for the first reactant with the first box body 11; the first box body 11 and the top cover 12 form a containing space for the second reactant. Specifically, the first box body 11 is assembled between the bottom cover 10 and the top cover 12 to form two independent spaces between the bottom cover 10 and the top cover 12. In some embodiments, the first box body 11 is fixedly connected to the bottom cover 10 to form a sealed containing space. Since the bottom cover 10 and the top cover 12 are fixedly connected to each other, a sealed containing space is also formed between the first box body 11 and the top cover 12; wherein, the connection manner between the first box body 11 and the bottom cover 10 includes but is not limited to snap connection, socket connection, screw connection, etc. Specifically, the first box body 11 encapsulates the first reactant in the second chamber 103 of the bottom cover 10; the first box body 11 and the top cover 12 form a storage space for containing the second reactant. At this time, the first reactant and the second reactant are respectively in two mutually isolated spaces. The second chamber 103 extends from the bottom cover 10 towards the side where the top cover 12 is located, and the size and contour of the second chamber 103 are consistent with the size and contour of the first box body 11, so as to form a sealed space between the first box body 11 and the second chamber 103. Preferably, the second chamber 103 is arranged away from the first chamber 101, so that the turbidity sensor 16 is as far as possible in the concentration uniform region after the first reactant and the second reactant are mixed, which is convenient for obtaining a more accurate detection result. The first reactant and the second reactant can be any raw materials capable of preparing volatile substances for disinfection. In some embodiments, the second reactant is an acidic liquid, such as hypochlorous acid and / or hydrochloric acid, etc., and the first reactant is a solid or solid powder (at this time, in order to facilitate the mixing of the first reactant with the second reactant after the home appliance sterilization module is activated, the solid or solid powder fills the second chamber 103 as much as possible or the liquid level of the second reactant should reach the position of the chamber where the first reactant is located). The fixed powder is generally chlorate or chlorite powder to generate chlorine dioxide gas; in other embodiments, the first reactant can be set as an acidic liquid and the second reactant can be set as a solid powder. At this time, it is convenient for the liquid reactant to flow out of the second chamber 103 to mix with the second reactant. In other embodiments, both the first reactant and the second reactant can be liquids, as long as the two react to generate a disinfection gas. It should be noted that the substance generated by the reaction of the first reactant and the second reactant preferably does not contain precipitation, so as to prevent the detection accuracy of the turbidity sensor 16 from being affected when the turbidity sensor 16 is included. It should be understood that the first reactant and the second reactant can be any combination of substances that can generate chlorine dioxide, and the state of the substance is not limited, such as: powder, liquid. In other embodiments, the first reactant is a peracid solution and the second reactant is a sodium chlorite aqueous solution, and the two liquid solutions react to generate chlorine dioxide gas.It should be noted that when the first reactant placed in the second chamber 103 is liquid, the liquid fills the second chamber 103 to facilitate mixing of the first reactant and the second reactant.

[0052] In some embodiments, the second chamber 103 is located at the top of the first chamber 101, that is, the mixing area of ​​the reactants is above the detection area of ​​the turbidity sensor 16. At this time, after the reactants are mixed, the disinfection gas will gradually diffuse to the area where the turbidity sensor is located due to its greater density than air, thereby facilitating detection by the turbidity sensor 16.

[0053] The volume of the second chamber 103 is at least 1 / 3 of the volume of the bottom cover 10 . In order to prepare as many volatile substances as possible for disinfection, the volume of the second chamber 103 may be at least one-half of the volume of the bottom cover 10, or the volume of the second chamber 103 is the volume of the bottom cover 10; in some embodiments, in addition to the second chamber 103, other accommodating chambers need to be provided on the bottom cover 10, and the accommodating chambers need to maintain a certain distance from the second chamber 103; specifically, in some embodiments, the volume of the second chamber 103 is between 1 / 3 and 1 / 2 of the volume of the bottom cover 10, on the one hand, the amount of reactant raw materials can be increased as much as possible, so as to prepare a larger amount of volatile substances for sterilization; on the other hand, when the bottom cover 10 includes a chamber for accommodating a turbidity sensor 16, preferably, there is a distance between the accommodating chamber where the turbidity sensor 16 is located and the second chamber 103, so that the turbidity sensor 16 is located at the center of the mixing of the second chamber 103 and another raw material, that is, the turbidity sensor 16 is as close as possible to the uniform concentration after the reactants are mixed, so as to ensure the detection accuracy of the turbidity sensor 16.

[0054] When using the household appliance sterilization module, if the remaining indicating body 100 stores the raw materials for preparing chlorine dioxide gas, it is necessary to lift the first box body 11 by external force so that the first reactant and the second reactant can be mixed. In some embodiments, the second chamber 103 also includes a receiving portion 102 for accommodating the interference structure. After the interference structure moves a distance in the receiving portion 102, it will interfere with the first box body 11 to lift the first box body 11. It should be noted that after the first box body 11 is lifted, it must still remain connected to the bottom cover 10 to prevent it from falling and affecting the measurement accuracy of the turbidity sensor. The receiving portion 102 is used to receive the interference structure, which in some embodiments is a push rod 15. The receiving portion 102 needs to be large enough to accommodate the push rod 15. The end of the push rod 15 received in the receiving portion 102 maintains a distance from the first box body 11 in the initial state. After the push rod 15 moves toward the first box body 11, the end of the push rod 15 contacts the first box body 11 so that a gap is generated between the first box body 11 and the bottom cover 10. In some embodiments, Figures 2-4As shown, the accommodating portion 102 is a third chamber arranged inside the second chamber 103, that is, the second chamber 103 also includes a third chamber, and a accommodating space for the first reactant is formed between the second chamber 103 and the third chamber; the third chamber provides a movement space for the conflicting structure, so as to conflict with the first box body 11 after movement and make the first box body 11 partially detach from the bottom cover 10; the third chamber extends away from the inner gallbladder side of the box body along the extension direction of the first chamber 101, and the third chamber, the conflicting structure, and the sealing member (such as the sealing gasket set on the conflicting structure) form a sealed space together to prevent the reactant from flowing out of the third chamber. The shape and size of the accommodating portion 102 are similar to the shape and size of the top rod 15. The end of the top rod 15 has a gap with the first box body 11 in the initial state, and the gap is generally set between 2mm-8mm, so that after the top rod 15 is subjected to external force, it can conflict with the first box body 11 by moving a small distance, and a gap is formed between the first box body 11 and the bottom cover 10. In other embodiments, the accommodating portion 102 is disposed at the outer peripheral edge of the second chamber 103 (not shown), and the shape and size of the accommodating portion 102 are similar to those of the ejector 15, and the accommodating portion 102 extends in the extension direction of the second chamber 103; initially, there is a gap between the end of the ejector 15 and the outer contour of the first box body 11, and after the ejector 15 is subjected to force, the end of the ejector 15 contacts the outer contour of the first box body 11, so that the first box body 11 is partially separated from the bottom cover 10 after being subjected to force. In order to allow the ejector 15 to easily contact and lift up the first box body 11, at this time, a contact portion matching the ejector 15 may be provided on the outer contour of the first box body 11, so as to facilitate lifting of the first box body 11. In addition, the first box body 11 can be a hinge structure or a flip structure, so that the first box body 11 initially forms a closed space with the bottom cover 10. When subjected to external force, the first box body 11 and the bottom cover 10 form a gap for the reactant to flow in or out. At this time, the first box body 11 remains on the bottom cover 10 and will not fall to affect the measurement accuracy of the turbidity sensor 16.

[0055] To ensure that the first box body 11 does not fall, the first box body 11 includes a protrusion 111 protruding from the first box body 11, and the protrusion 111 remains on the bottom cover 10 after the home appliance sterilization module is activated. Specifically, the first box body 11 includes a protrusion 111 that extends away from or towards the home appliance inner container 200. The protrusion 111 is hung or sleeved on the bottom cover 10 or the accommodating portion 102 of the bottom cover 10 before and after the home appliance sterilization module is activated. When the bottom cover 10 includes a third chamber, the opening size of the protrusion 111 is greater than the opening size of the third chamber and the protrusion 111 can be of any shape, or the opening size of the protrusion 111 is less than the opening size of the third chamber and the protrusion 111 can be of any shape. In some embodiments, the protrusion 111 extends away from the home appliance inner container 200. At this time, the opening of the protrusion 111 is larger than the opening of the third chamber, and the protrusion 111 is initially hung on the third chamber. In other embodiments, the protrusion 111 extends towards the home appliance inner container 200. At this time, the opening of the protrusion 111 is smaller than the opening of the third chamber, and the protrusion 111 is initially sleeved on the third chamber. When the first box body 11 is stressed, the first box body 11 is lifted, but due to the existence of the protrusion 111, the first box body 11 can still be held on the third chamber of the bottom cover 10 through the protrusion 111 and will not fall.

[0056] In some embodiments, in order to form a gap between the first box body 11 and the bottom cover 10 after the first box body 11 is stressed, the first box body 11 can be a flip structure provided on the bottom cover 10. Initially, the flip structure is sealed with the bottom cover 10. After the ejector rod 15 lifts the flip structure, the second reactant is mixed with the first reactant.

[0057] When the second reactant is a liquid, to ensure that the first box body 11 can at least partially separate from the bottom cover 10 and the second reactant can easily flow into the second chamber 103, the liquid level of the second reactant in the top cover 12 is at least higher than the outer contour of the first box body 11, so that after the first box body 11 is at least partially separated from the bottom cover 10, the second reactant can enter the sealed space formed between the first box body 11 and the bottom cover 10. In some embodiments, when the home appliance sterilization module is placed vertically, since the first reactant is located in the sealed space formed by the first box body 11, the second chamber 103, and the accommodating portion 102, therefore, the liquid level of the second reactant is at least higher than the position where the bottom of the outer contour of the first box body 11 is located. Preferably, the liquid level of the second reactant is higher than the position where the top of the outer contour of the first box body 11 is located, to ensure that the second reactant and the first reactant can be easily and fully mixed. In other embodiments, when the home appliance sterilization module is horizontally suspended at the top of the inner container, the liquid level of the second reactant is at least higher than the position where the entire outer contour of the first box body 11 is located. Preferably, the liquid level of the second reactant fills the entire top cover 12, to ensure that the second reactant and the first reactant can be easily mixed.

[0058] The top cover 12 is used to form a sealed structure with the bottom cover 10. At least part of the sealed structure includes the ventilation part of several ventilation holes, and the ventilation part is externally sealed and covered with a breathable film 13, which is made of a breathable and water-impermeable material. Before the household appliance sterilization module is used, the second reactant is inside the top cover 12, and the second reactant will not flow out of the breathable film 13 through the ventilation part; when the household appliance sterilization module is used, the first reactant and the second reactant are mixed to generate chlorine dioxide gas, and the chlorine dioxide gas can enter the household appliance box body through the breathable film 13.

[0059] In some embodiments, a second box body 14 is further included. The second box body 14 presses the breathable film 13 onto the top cover 12. At this time, the second box body 14 and the top cover 12, the bottom cover 10 form a consistent overall contour, which can ensure the integrity and aesthetics of the household appliance sterilization module; in addition, the second box body 14 presses the breathable film 13 onto the top cover 12, which can prevent the sealing performance from decreasing after long-term use of the breathable film 13 and form a gap with the top cover 12. The second box body 14 also includes several ventilation holes to facilitate gas to enter the household appliance box body.

[0060] The breathable film 13 is made of a breathable and water-impermeable material, which can be a breathable film (such as a PE film, a PUW film, etc.), silica gel, non-woven fabric, etc. On the one hand, it can facilitate the passage of the gas of the volatile matter, and on the other hand, it can block the liquid from overflowing the household appliance sterilization module. In addition, the breathable film 13 can prevent dust outside the sterilization module from entering the household appliance sterilization module. Since different breathable films 13 have different breathable rates, a suitable breathable film 13 can be selected according to the volume of the household appliance to adjust the breathable amount of the volatile matter in the same time period.
