Abstract

The present invention provides a mounting structure for a household appliance sterilization module, comprising: an embedded box and a first protrusion. When the household appliance sterilization module is activated, the first protrusion abuts against a push rod, causing the push rod to move relative to the housing of the household appliance sterilization module, thereby breaking the isolation structure within the household appliance sterilization module and allowing at least two reactants in an isolated state within the household appliance sterilization module to mix with each other to generate volatile substances for sterilization. The present invention also provides a refrigerator. The mounting structure for a household appliance sterilization module provided by the present invention, by triggering the push rod to move within the household appliance sterilization module to break the isolation structure, solves the problem that conventional sterilization modules are inconvenient for on-site preparation of disinfectant gas.

Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and in particular relates to a household appliance sterilization module installation structure and a refrigerator. Background Art

[0002] Currently, all types of home appliances on the market are equipped with consumable modules to purify the air inside the appliance or keep items fresh. Each consumable module has a limited lifespan, and irregular replacement can easily lead to secondary contamination. Existing consumable modules store disinfectant gas for direct sterilization, but limited storage space results in a short lifespan. If the consumable module is configured to generate disinfectant gas on-site, it requires a convenient way to trigger the reaction of the disinfectant gas-generating raw materials within it during actual use.

[0003] Therefore, it is necessary to improve the installation structure of the existing sterilization module, optimize its structural design, and design a new installation structure of the household appliance sterilization module to solve the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the first object of the present invention is to propose a household appliance sterilization module installation structure for fixedly installing the household appliance sterilization module; comprising:

[0005] The embedded box is arranged on the inner tank of the home appliance to form a concave structure on the wall of the inner tank of the home appliance;

[0006] a first protrusion protruding from the open surface of the embedded box and configured to abut against a top rod on the home appliance sterilization module;

[0007] When the household appliance sterilization module is activated, the first protrusion abuts against the push rod, causing the push rod to move relative to the housing of the household appliance sterilization module, thereby breaking the isolation structure inside the household appliance sterilization module, so that at least two reactants in an isolated state in the household appliance sterilization module mix with each other to generate volatile substances for sterilization.

[0008] Preferably, it further comprises a positioning seat protruding from the open surface of the embedded box, for locating the installation position of the household appliance sterilization module relative to the embedded box.

[0009] Preferably, the device further comprises a patch cord terminal, and the patch cord terminal is used for plugging in the turbidity sensor.

[0010] Preferably, the patch cord terminal is arranged away from the first protrusion.

[0011] Preferably, the device further comprises an outer cover, which is embedded into the embedded box from the open surface of the embedded box so that the outer cover and the embedded box form a consistent overall outline.

[0012] A second object of the present invention is to provide a refrigerator comprising a cabinet, a door, and a home appliance sterilization module, wherein the cabinet inner liner comprises the embedded box as described above, and the embedded box is used to place and activate the home appliance sterilization module.

[0013] Preferably, the household appliance sterilization module includes:

[0014] The box body is arranged on the inner container of the household appliance and includes a receiving space for receiving the sterilizing substance or the sterilizing substance reaction raw material;

[0015] At least one isolation structure for forming at least two independent chambers in the accommodating space;

[0016] The first protrusion abuts against the ejector rod, so that the ejector rod contacts and breaks the isolation structure in the home appliance sterilization module, so that the reactants in the independent chambers mix with each other to generate volatile substances for sterilization.

[0017] Preferably, the box body comprises:

[0018] Bottom cover, configured on the inner tank of the appliance;

[0019] The top cover is fixedly connected to the bottom cover and forms together with the bottom cover a storage space for sterilizing substances or sterilizing substance reaction raw materials.

[0020] Preferably, the bottom cover further comprises a first chamber on the side facing away from the appliance inner tank, which forms a first reactant accommodation space with the isolation structure; the isolation structure and the top cover form a second reactant accommodation space.

[0021] Preferably, the bottom cover further comprises a second chamber near the inner tank of the household appliance, at least the second chamber is made of a transparent material, and the second chamber is used to accommodate a turbidity sensor.

[0022] Preferably, the first chamber further includes a third chamber, and a storage space for the first reactant is formed between the first chamber and the third chamber; the third chamber provides a movement space for the top rod to contact the isolation structure after movement and make the isolation structure at least partially separate from the bottom cover.

[0023] Preferably, the isolation structure includes a second protrusion protruding from the isolation structure, and the second protrusion remains on the bottom cover after the home appliance sterilization module is activated.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) By setting up a household appliance sterilization module installation structure, while fixing the household appliance sterilization module, it is convenient to quickly trigger a chemical reaction inside the module by pushing the push rod to generate gas for disinfection.

[0026] (2) A positioning seat is provided, which is protruded from the open surface of the embedded box to locate the installation position of the home appliance sterilization module relative to the embedded box to prevent the first protrusion from being unable to break the isolation structure.

[0027] (3) By setting a patch cord terminal, the patch cord terminal is used to plug in a turbidity sensor used to detect the remaining amount of disinfectant gas in the home appliance sterilization module, so as to obtain the remaining amount of disinfectant gas in the home appliance sterilization module and promptly remind the user to replace it.

[0028] (4) The detection accuracy of the turbidity sensor is improved by arranging the patch cord terminal away from the first protrusion.

[0029] (5) An outer cover is provided, which is embedded into the embedded box from the open surface of the embedded box so that the outer cover and the embedded box form a consistent overall contour, so that the outer cover can cover the punching and assembly seams of the inner liner, thereby improving the overall aesthetics and texture of the embedded box.

[0030] (6) The present invention also provides a refrigerator, comprising a cabinet, a door, and a household appliance sterilization module. The cabinet inner liner includes the embedded box as mentioned above, which is used to place and activate the household appliance sterilization module, avoiding direct installation resulting in the formation of multiple installation holes on the inner liner, which affects the performance of the inner liner.

[0031] (7) A household appliance sterilization module is provided, comprising a box body, which is arranged on the inner container of the household appliance, and includes a storage space for storing sterilizing substances or sterilizing substance reaction raw materials; at least one isolation structure is used to form at least two independent chambers in the storage space; a first protrusion abuts against a top rod, so that the top rod contacts and breaks the isolation structure in the household appliance sterilization module, so that the reactants in the independent chambers mix with each other to generate volatile substances for sterilization; thereby, a large amount of volatile substances for sterilization are prepared in real time.

[0032] (8) The sterilization module includes a bottom cover and a top cover to form a space for accommodating disinfectant volatiles, which facilitates the fixation of the sterilization module; a first chamber is provided on the side of the bottom cover away from the inner tank of the household appliance to form a space for accommodating a reactant, thereby ensuring the sealing of the reactant before mixing.

[0033] (9) A second chamber is provided on the bottom cover near the inner tank of the household appliance, at least the second chamber is made of a transparent material, and the second chamber is used to accommodate a turbidity sensor so as to detect the change in the residual amount of volatile substances used for sterilization inside the second chamber.

[0034] (10) By arranging the third chamber in the first chamber, a storage space for the first reactant is formed between the first chamber and the third chamber; the third chamber provides a movement space for the push rod, so that after movement, it contacts the isolation structure and causes the isolation structure to at least partially separate from the bottom cover, thereby increasing the contact area between the push rod and the isolation structure, ensuring that the isolation structure can be easily lifted.

[0035] (11) By providing a second protrusion protruding from the isolation structure on the isolation structure, the second protrusion remains on the bottom cover after the home appliance sterilization module is activated, so as to ensure that the isolation structure will not fall after being subjected to external force, thereby ensuring that the detection accuracy of the turbidity sensor is not affected.

[0036] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and to implement it according to the contents of the description, the following preferred embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0049] Next, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0050] Example 1

[0051] like Figure 1-8As shown, a household appliance sterilization module installation structure is used to fix the household appliance sterilization module 100. The fixed installation includes but is not limited to detachable connection methods such as snap-on, socket-on, and screw-on. The household appliance sterilization module 100 is used to sterilize the inside of the household appliance box to maintain a good storage environment inside the household appliance box. The household appliance can be a household appliance for storing items such as a refrigerator or freezer. The structure specifically includes: a pre-embedded box 17, which is configured on the inner tank 200 of the household appliance to form a concave structure on the wall of the inner tank of the household appliance; specifically, the pre-embedded box 17 is pre-placed in the inner tank 200 of the household appliance, and then the pre-embedded box 17 and the inner tank 200 are foamed; in some embodiments, when the pre-embedded box 17 includes a patch cord terminal 172, the pre-embedded box 17 is pre-placed in the inner tank 200 of the household appliance, the patch cord terminal 172 is installed in the pre-embedded box 17, and then the pre-embedded box 17 and the inner tank 200 are foamed; the pre-embedded box 17 is configured at any position in the inner tank 200 of the household appliance, such as the side of the inner tank 200, the top of the inner tank 200, etc., and the pre-embedded box 17 is used to fix the installation. The household appliance sterilization module 100 is installed; the structure also includes a first protrusion 171, which is protruding from the open surface of the embedded box 17 to abut against the push rod 15 on the household appliance sterilization module 100; the open surface refers to the surface where the air in the inner tank 200 enters the embedded box 17, that is, the side of the embedded box 17 close to the household appliance door; when the household appliance sterilization module 100 is activated, the first protrusion 171 abuts against the push rod 15, so that the push rod 15 moves relative to the housing of the household appliance sterilization module 100, so as to break the isolation structure in the household appliance sterilization module 100, so that at least two reactants in an isolated state in the household appliance sterilization module 100 are mixed with each other to generate volatile substances for sterilization. Among them, the movement of the top rod 15 relative to the housing of the household appliance sterilization module 100 means that since the isolation structure is arranged inside the household appliance sterilization module to form at least two independent chambers inside it, in order to break the isolation structure, the top rod 15 needs to resist the isolation structure. At this time, the top rod 15 needs to move relative to the outer housing of the household appliance sterilization module or relative to the isolation structure. When the household appliance sterilization module 100 is a box body, after activating the household appliance sterilization module, the top rod 15 needs to move relative to the box body to resist the isolation structure. In some embodiments, the isolation structure may be a membrane structure, and breaking the membrane structure means puncturing the membrane; in other embodiments, the isolation structure may be a layer of baffle, which will move relative to the accommodating space in the box body under the action of external force, so that the reactants in the independent chambers themselves are mixed with each other. At this time, the external mechanism acting on the baffle is also a breaking structure.

[0052] When the two reactants are a first reactant and a second reactant, the first reactant and the second reactant can be any raw materials capable of producing a gas for disinfection. In some embodiments, the second reactant is an acidic liquid, such as hypochlorous acid and / or hydrochloric acid, and the first reactant is a solid or solid powder (in this case, to facilitate mixing of the first reactant with the second reactant after the home appliance sterilization module 100 is activated, the solid or solid powder is filled as much as possible in the first chamber 103 or the liquid level of the second reactant is to reach the position of the chamber where the first reactant is located). The fixed powder is generally chlorate or chlorite powder, which is mixed to generate chlorine dioxide gas. In other embodiments, the first reactant can be set as an acidic liquid and the second reactant as a solid powder. In this case, it is convenient for the liquid reactant to flow out of the first chamber 103 and mix with the second reactant. In other embodiments, the first reactant and the second reactant can both be liquids, and it is only necessary that the reaction between the two can generate disinfectant gas. It should be noted that the substance generated by the reaction of the first reactant and the second reactant should preferably not contain precipitates, so as to prevent the turbidity sensor 16 from being affected in its detection accuracy when the turbidity sensor 16 is included.

[0053] To facilitate installation and ensure that the ejector rod 15 can successfully break through the isolation structure, a positioning seat 177 is also included. This positioning seat 177 is protruded from the open surface of the embedded box 17 and is used to locate the installation position of the home appliance sterilization module 100 relative to the embedded box. At this time, when the first protrusion 171 is installed on the positioning seat 177, the first protrusion 171 can be set at any position on the positioning seat 177. In other words, the positioning seat 177 achieves preliminary positioning and ensures that the ejector rod 15 can contact the isolation structure.

[0054] In order to detect the remaining amount of volatile substances used for disinfection in the household appliance sterilization module 100, a connector terminal 172 is also included. The connector terminal 172 is used to plug in the turbidity sensor 16 for detecting the remaining amount of disinfectant gas in the household appliance sterilization module. In order to ensure the detection accuracy of the turbidity sensor 16, the connector terminal 172 is set away from the first protrusion 171 so that the turbidity sensor 16 is as close as possible to the uniform area after the reactants are mixed. Specifically, the turbidity sensor 16 is set away from the first chamber 103 where the first reactant is stored. When the second reactant is mixed with the first reactant, the concentration of the disinfectant gas generated in and near the first chamber 103 is higher, while the concentration of the disinfectant gas away from the first chamber 103 is relatively low; after the disinfectant gas diffuses for a period of time, the concentration of the disinfectant gas tends to be balanced. Therefore, in order to ensure the accuracy of the measured sterilizing gas concentration, the turbidity sensor 16 is arranged away from the first chamber 103 , that is, the connector terminal 172 for installing the turbidity sensor 16 is arranged away from the first protrusion 171 that drives the push rod 15 to move.

[0055] In order to ensure the aesthetics of the embedded box 17, in some embodiments, the installation structure also includes an outer cover 173, which is embedded in the embedded box 17 from the open surface of the embedded box 17, so that the outer cover 173 and the embedded box 17 form a consistent overall contour; specifically, the outer cover 173 is an outer cover 173 assembled from the inside of the inner liner 200, and the outer cover 173 is fixedly installed in the embedded box 17; the shape and size of the outer cover 173 are set according to the shape and size of the embedded box, and the outer cover 173 is fixedly connected to the embedded box 17 to cover the punching assembly flash seam of the inner liner 200, and the fixed connection includes snap connection, sleeve connection, etc. In some embodiments, in order to further enhance the aesthetics of the embedded box 17, the outer cover 173 includes an inner chamber 175, the size of the inner chamber 175 matches the size of the embedded box 17, and the inner chamber 175 extends along the side edge of the embedded box 17 so that the outer cover 173 is embedded in the embedded box 17 through the inner chamber 175; in addition, since the embedded box 17 is a recessed structure formed on the wall of the inner liner 200, the outermost periphery of the recessed structure includes a circle of outer walls, and the outer cover 173 includes a receiving area near the side of the embedded box 17, the size and shape of the receiving area match the size and shape of the outer wall, so that the outer cover 173 is assembled on the embedded box through the receiving area. Since the receiving area completely matches the circle of outer walls, at this time, the circle of outer walls is embedded in the receiving area to form an overall structure consistent with the embedded box. At this time, the inner chamber 175 of the outer cover 173 and the outer cover outline cover the embedded box, thereby enhancing the overall aesthetics of the embedded box.

[0056] To facilitate the detachable connection of the outer cover 173, the inner chamber 175 also includes a plurality of mounting slots 174. The mounting slots 174 can be set at any position on the outer cover 173. It is only necessary for the mounting slots 174 to match the mounting positions 176 on the embedded box 17 to achieve a fixed connection between the outer cover 173 and the embedded box 17. This fixed connection includes a snap connection, a sleeve connection, etc. It should be understood that the mounting slots 174 can be a mounting position, and the mounting position 176 can be a mounting slot. When the outer cover 173 is fixed to the embedded box 17, the household appliance sterilization module can be fixedly connected to the embedded box 17 with the outer cover 173 through the mounting slots 174, for example, by snap connection, groove connection, etc.

[0057] The first protrusion 171 is arranged directly opposite the push rod 15 on the home appliance sterilization module 100. When the home appliance sterilization module 100 is fixedly installed in the embedded box 17, the first protrusion 171 provides a driving force for the push rod 15, so that the push rod 15 moves within the space containing the push rod 15 in the home appliance sterilization module 100, thereby breaking the isolation structure within the home appliance sterilization module 100, allowing the reactants in an isolated state before the home appliance sterilization module 100 is installed to mix with each other to generate a disinfectant gas for sterilization. The isolation structure is located within the movement space of the push rod 15, and before the home appliance sterilization module 100 is activated, the isolation structure is used to independently separate the two reactants into two independent chambers, so that after the home appliance sterilization module 100 is activated, a large amount of disinfectant gas can be prepared on site in real time.

[0058] To facilitate the movement of ejector pin 15 within household appliance sterilization module 100, the shape / contour of first protrusion 171 can be configured to conform to the shape / contour of the force-bearing end of ejector pin 15, allowing first protrusion 171 to align with ejector pin 15 for precise propulsion. In some embodiments, when ejector pin 15 is cylindrical, first protrusion 171 is a circular boss. To ensure that ejector pin 15 can be easily triggered, in some embodiments, first protrusion 171 is a raised structure formed by stacking multiple bosses, which are stacked along the direction of motion of ejector pin 15 to easily trigger the movement of ejector pin 15.

[0059] Example 2

[0060] like Figure 1-8 As shown, a refrigerator includes a cabinet, a door, and a home appliance sterilization module. The cabinet inner liner includes a pre-embedded box 17 as described in the above embodiment. The pre-embedded box 17 is used to place and activate the home appliance sterilization module 100; that is, the home appliance sterilization module 100 is fixedly installed in the cabinet inner liner 200 through the pre-embedded box 17; the pre-embedded box 17 can be set at any position in the inner liner 200, such as the side or top of the inner liner 200; and the first protrusion 171 on the pre-embedded box 17 breaks the internal isolation structure.

[0061] In order to facilitate the on-site preparation of disinfection volatiles (gas used for disinfection or liquid or gel containing disinfection gas) and form a large amount of disinfection volatiles in a limited storage space, in some embodiments, the household appliance sterilization module 100 includes: a box body, configured on the household appliance inner tank 200, including a accommodating space for accommodating sterilization substances or sterilization substance reaction raw materials; at least one isolation structure, used to form at least two independent chambers in the accommodating space; the first protrusion 171 abuts against the top rod 15, so that the top rod 15 conflicts with and breaks the isolation structure in the household appliance sterilization module 100, so that the reactants in the independent chambers mix with each other to generate volatiles for sterilization.

[0062] In some embodiments, the box body includes: a bottom cover 10, which is disposed on the appliance inner container 200; and a top cover 12, which is fixedly connected to the bottom cover 10 and forms a storage space for the sterilizing substance or the reactants of the sterilizing substance together with the bottom cover 10. In some embodiments, this fixed connection is manifested by ultrasonic welding of the bottom cover 10 to the top cover 12; in other embodiments, the bottom cover 10 and the top cover 12 can be fixed by means of snap-fitting, sleeve-fitting, screwing, or bonding. In other words, the fixed connection between the top cover 12 and the bottom cover 10 includes detachable and non-detachable connections. When a non-detachable connection is used, the sealing of the appliance sterilization module 100 is ensured.

[0063] In some embodiments, the bottom cover 10 includes a first chamber 103 for storing a first reactant on the side away from the appliance inner tank 200. The first chamber 103 has a certain depth for storing the first reactant. The first chamber 103 can be set to any shape. In some embodiments, the first chamber 103 extends toward the side away from the appliance inner tank 200; the top cover 12 is fixedly connected to the bottom cover 10, and the second reactant is stored in the top cover 12; when the isolation structure is the first box body 11, it is used to encapsulate the first reactant in the first chamber 103 and separate the first reactant and the second reactant into two independent chambers, that is, the first box body 11 and the first chamber 103 form a storage space for the first reactant; the first box body 11 and the top cover 12 form a storage space for the second reactant; the first box body 11 and the first chamber 103 can be detachably connected or non-detachably connected by means of sleeve connection, snap connection, or screw connection; or the first box body 11 and the first chamber 103 are ultrasonically welded.

[0064] In some embodiments, a receiving portion 102 for accommodating a push rod 15 is further included near the first chamber 103. After the push rod 15 moves a certain distance in the receiving portion 102, it contacts the first box body 11 so that the first box body 11 is at least partially separated from the bottom cover 10. It should be noted that when a turbidity sensor is included, the first box body 11 must remain connected to the bottom cover 10 after being lifted up to prevent the measurement accuracy of the turbidity sensor from being affected after falling. The receiving portion 102 is used to accommodate the push rod. The size of the receiving portion 102 must be able to accommodate the push rod 15. The end of the push rod 15 accommodated 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, the accommodating portion 102 is a third chamber arranged inside the first chamber 103, that is, the first chamber 103 also includes a third chamber, and a accommodating space for the first reactant is formed between the first 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 at least partially separated from the bottom cover 10; the third chamber extends along the extension direction of the first chamber 103 away from the inner gallbladder side of the box body, and the third chamber, the top rod 15, and the sealing member (such as a sealing gasket set on the top rod 15) together form a sealed space 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. 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 smaller 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 on the outer peripheral edge of the first chamber 103 (not shown), and the shape and size of the accommodating portion 102 are similar to those of the ejector pin 15, and the accommodating portion 102 extends in the extension direction of the first chamber 103; initially, there is a gap between the end of the ejector pin 15 and the outer contour of the first box body 11. After the ejector pin 15 is subjected to force, the end of the ejector pin 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 the force is applied. In order to enable the ejector pin 15 to easily contact and lift the first box body 11, at this time, a contact portion matching the ejector pin 15 can be provided on the outer contour of the first box body 11 to facilitate lifting 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.

[0065] To prevent the first housing 11 from falling, the first housing 11 includes a second protrusion 111 protruding from the first housing 11. The second protrusion 111 remains on the bottom cover 10 even after the appliance sterilization module is activated. Specifically, the first housing 11 includes a second protrusion 111 extending away from or toward the side of the appliance inner container 200. The second protrusion 111 is hooked or sleeved onto the bottom cover 10 or the accommodating portion 102 of the bottom cover 10 before and after the appliance sterilization module 100 is activated. When the bottom cover 10 includes a third chamber, the opening of the second protrusion 111 can be larger than the opening of the third chamber and can have any shape, or the opening of the second protrusion 111 can be smaller than the opening of the third chamber and can have any shape. In some embodiments, the second protrusion 111 extends away from the appliance inner container 200. In this case, the opening of the second protrusion 111 is larger than the opening of the third chamber, and the second protrusion 111 is initially attached to the third chamber. In other embodiments, the second protrusion 111 extends toward the appliance inner container 200. In this case, the opening of the second protrusion 111 is smaller than the opening of the third chamber, and the second protrusion 111 is initially attached to the third chamber. When the first box body 11 is subjected to force, the first box body 11 is lifted up, but because of the presence of the second protrusion 111, the first box body 11 can still be retained in the third chamber on the bottom cover 10 by the second protrusion 111 and will not fall.

[0066] In some embodiments, in order to form a gap between the first box body 11 and the bottom cover 10 after being subjected to force, the first box body 11 can be a flip-top structure arranged on the bottom cover 10. Initially, the flip-top structure and the bottom cover 10 remain sealed. After the top rod 15 lifts the flip-top structure, the second reactant and the first reactant are mixed.

[0067] In order to prevent the disinfecting gas in the household appliance sterilization module 100 from remaining in the household appliance box after it is used up, there is an urgent need for a method to indicate the remaining disinfecting gas in the household appliance sterilization module 100. In some embodiments, the bottom cover 10 further includes a second chamber 101 near the household appliance inner tank 200, and at least the second chamber 101 is made of a transparent material. The second chamber 101 is used to accommodate a turbidity sensor. The shape and size of the second chamber 101 are set according to the size and shape of the turbidity sensor 16 so that the turbidity sensor 16 can be stably placed in the second chamber 101. It should be understood that when the turbidity sensor 16 is included, the first box body 11 as an isolation structure can only be partially separated from the bottom cover 10 to avoid affecting the detection accuracy of the turbidity sensor after falling.

[0068] To ensure the detection accuracy of turbidity sensor 16 and maximize its contact with the volatile substances within the storage space, second chamber 101 is preferably configured as a depression extending from bottom cover 10 toward the side away from appliance inner container 200. In this case, second chamber 101 is located within the storage space formed by bottom cover 10 and top cover 12. That is, the substances within the storage space are arranged around turbidity sensor 16, ensuring that turbidity sensor 16 can quickly detect color changes within the storage space. When the storage space contains chlorine dioxide gas, a volatile substance used for sterilization, the chlorine dioxide gas needs to be loaded into a gel-like substance. In this case, the turbidity sensor 16 detects the color change of the gel within the storage space to determine the remaining amount of chlorine dioxide gas. When the storage space contains raw materials for preparing volatile substances, the turbidity sensor 16 detects the color change of the liquid or gel within the storage space to determine the remaining amount of volatile substances.

[0069] For ease of processing, the bottom cover 10 can be made directly from a transparent material to facilitate detection of color changes within the accommodating space by the turbidity sensor 16. To facilitate transportation and storage, in some embodiments, the first box body 11 is detachably connected to the first chamber 103. When the first box body 11 is pushed by the push rod 15, the first box body 11 falls off from the first chamber 103, allowing the first reactant and the second reactant to be fully mixed.

[0070] In order to facilitate the residual detection of the disinfection gas in the accommodating space formed by the bottom cover 10 and the top cover 12, the first box body 11 is hung on or sleeved on the first chamber 103 of the bottom cover 10, or the first box body 11 is set to a flip structure or a hinge structure fixed on the first chamber 103 of the bottom cover 10; at this time, when there is a turbidity sensor 16 on the bottom cover 10 to detect the accommodating space, the dropped first box body 11 will affect the detection accuracy of the turbidity sensor 16; at this time, it is necessary to set the first box body 11 to remain on the bottom cover 10 after being lifted up so as not to affect the detection accuracy of the turbidity sensor 16.

[0071] When the reactants include a first reactant and a second reactant, the first reactant and the second reactant can be any raw material capable of producing a gas for disinfection. In some embodiments, the second reactant is an acidic liquid, such as hypochlorous acid and / or hydrochloric acid, and the first reactant is a solid or solid powder (in this case, to facilitate mixing of the first reactant with the second reactant after the home appliance sterilization module 100 is activated, the solid or solid powder is filled as much as possible in the first chamber 103 or the liquid level of the second reactant is to reach the position of the chamber where the first reactant is located). The fixed powder is generally chlorate or chlorite powder, which is mixed to generate chlorine dioxide gas. In other embodiments, the first reactant can be set as an acidic liquid and the second reactant as a solid powder. In this case, it is convenient for the liquid reactant to flow out of the first chamber 103 and mix with the second reactant. In other embodiments, the first reactant and the second reactant can both be liquids, and it is only necessary that the reaction between the two can generate disinfectant gas. It should be noted that the substance generated by the reaction of the first reactant and the second reactant should preferably not contain precipitates, so as to prevent the turbidity sensor 16 from being affected in its detection accuracy when the turbidity sensor 16 is included.

[0072] In some embodiments, the household appliance sterilization module 100 includes: a bottom cover 10, which is fixedly connected to the top cover 12 to form the household appliance sterilization module 100. In some embodiments, the fixed connection is manifested as 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 snapping, sleeve connection, screw connection, bonding, etc., that is, the fixed connection method between the top cover 12 and the bottom cover 10 includes a detachable connection and a non-detachable connection. When a non-detachable connection is adopted, the sealing of the household appliance sterilization module 100 can be guaranteed. The bottom cover 10 includes a first chamber 103 for storing a first reactant on the side away from the inner tank 200 of the appliance. The first chamber 103 has a certain depth for storing the first reactant. The first chamber 103 can be set to any shape. In some embodiments, the first chamber 103 extends away from the inner tank 200 of the appliance box; the top cover 12 is fixedly connected to the bottom cover 10, and the second reactant is stored in the top cover 12; the first box body 11 is used to encapsulate the first reactant in the first chamber 103 and separate the first reactant and the second reactant into two independent chambers. The first box body 11 and the first chamber 103 can be connected by sleeve connection, snap connection, or screw connection. Removable connection or non-detachable connection; or ultrasonic welding of the first box body 11 and the first chamber 103, in which case the first box body 11 is made of a fragile material (i.e., the ejector rod 15 damages the first box body 11); further comprising a receiving portion 102 for accommodating the ejector rod 15, which is disposed around the first chamber 103, the receiving portion 102 is used to place the ejector rod 15 and form a movement space for the ejector rod 15, and the receiving portion 102 is disposed near the first chamber 103; the first protrusion 171 on the embedded box 17 pushes the ejector rod 15 toward the first box body 11 to lift the first box body 11 so that the first reactant and the second reactant located on both sides of the first box body 11 are mixed with each other.

[0073] It should be understood that the first and second reactants can be any raw materials capable of producing a gas for disinfection. In some embodiments, the second reactant is an acidic liquid, such as hypochlorous acid and / or hydrochloric acid, and the first reactant is a solid powder, typically a chlorate or chlorite powder, to produce chlorine dioxide gas when mixed. Alternatively, the first reactant can be an acidic liquid and the second reactant a solid powder. In other embodiments, both the first and second reactants can be liquids; it is sufficient that they react to produce a disinfectant gas. It is important to note that the product of the reaction between the first and second reactants should preferably not contain precipitates to prevent degradation of the detection accuracy of the turbidity sensor 16 when included.

[0074] To control the amount of volatiles released from the appliance sterilization module 100, a breathable membrane 13 is included. This membrane 13 follows the contour of the top cover 12 and seals over the vents in the top cover 12. The vents can be configured in any shape and position. The membrane 13 follows the contour of the top cover 12 to ensure a tight seal between the two components, preventing gaps between the two components that could allow volatiles to enter the appliance's interior without passing through the membrane 13. The membrane 13 is made of an air-permeable, water-tight material to prevent the escape of reactants and / or reactant products. In this embodiment, the membrane is easily processed and ensures air-tightness and water-tightness. Because the breathable membrane is relatively soft and easily damaged, some embodiments further include a second housing 14, which presses the breathable membrane 13 onto the top cover 12. This creates a consistent overall profile between the second housing 14, the top cover 12, and the bottom cover 10, ensuring the integrity and aesthetics of the appliance sterilization module. Furthermore, the second housing 14 presses the breathable membrane 13 onto the top cover 12, preventing the membrane 13 from losing its sealing properties after long-term use and forming a gap between the membrane and the top cover 12. The second housing 14 also includes a number of ventilation holes to facilitate air entry into the appliance housing.

[0075] The breathable membrane 13 is made of an air-permeable, water-impermeable material, such as a breathable membrane (e.g., PE film, PUW film, etc.), silicone, or non-woven fabric. It facilitates the passage of volatile gases while preventing liquids from escaping the sterilization module 100. Furthermore, the breathable membrane 13 prevents dust from entering the sterilization module 100. Because different breathable membranes 13 have different permeability rates, the appropriate breathable membrane 13 can be selected based on the volume of the appliance to adjust the amount of volatile gases that can be breathed through within a given time period.
