[0033] In order to more fully understand the invention described herein, the following embodiments are set forth. It should be understood that these embodiments are for illustrative purposes only and should not be construed as limiting the invention in any way.

[0034] Embodiment 1

[0035] As Figures 1-5As shown, a mounting structure for a sterilization module of a household appliance is a household appliance such as a refrigerator or freezer that stores food for a long time and needs to be sterilized. The mounting structure includes a bottom cover 10, which is arranged on the inner tank 200 of the household appliance, and is used to be fixedly connected with the top cover 12 and form a corresponding accommodation space inside the top cover 12 and the bottom cover 10, wherein the bottom cover 10 and the top cover 12 can be ultrasonically welded; in addition, the bottom cover 10 and the top cover 12 can be fixed by means of snap connection, sleeve connection, screw connection, bonding, etc., that is, the fixed connection method of the top cover 12 and the bottom cover 10 includes a detachable connection and a non-detachable connection. When the non-detachable connection is adopted, the sealing of the sterilization module for the household appliance can be ensured; the bottom cover 10 includes a first chamber 101 for accommodating a first reactant, the first chamber 101 has a certain depth for storing the first reactant, and the first chamber 101 can be set to any shape. In some embodiments, the first chamber 101 extends away from the inner tank of the household appliance box. The mounting structure also includes a first box body 11, which is used to be fixedly connected to the bottom cover 10; before the home appliance sterilization module 100 is activated, the first box body 11 encapsulates the first reactant in the first chamber 101 to prevent the first reactant from flowing out of the first chamber 101. Specifically, the first box body 11 is detachably connected to the bottom cover 10, and the detachable connection is different from the fixed connection method between the bottom cover 10 and the top cover 12, and the fixed connection method between the bottom cover 10 and the first box body is easy to remove under the action of external force. The space formed by the top cover 12 and the first box body 11 contains the second reactant, that is, the second reactant is encapsulated in the sealed space formed by the bottom cover 10 and the top cover 12. At the same time, the first box body 11 separates the first reactant and the second reactant in two independent spaces, that is, before the home appliance sterilization module 100 is used, the first reactant exists in the sealed space formed by the bottom cover 10 and the first box body 11, and the second reactant exists in the sealed space formed by the bottom cover 10, the first box body 11 and the top cover 12. After the home appliance sterilization module 100 is activated, the first box body 11 is at least partially separated from the bottom cover 10 under the action of external force, so that the first reactant and the second reactant are mixed to generate volatiles for sterilization; it should be understood that "at least partially separated" can refer to the first box body 11 partially separated from the bottom cover 10, that is, there is a gap between the first box body 11 and the bottom cover 10, but the first box body 11 does not leave the bottom cover 10; "at least partially separated" can also refer to the first box body 11 completely separated from the bottom cover 10, that is, the first box body 11 falls into the accommodation space formed by the bottom cover 10 and the top cover 12. In some embodiments, the first box body 11 is lifted up by an external force and then falls off the bottom cover 10, so that the second reactant can be quickly mixed with the first reactant. In other embodiments, the first box body 11 forms a gap with the first chamber 101 under the action of an external force, so that the first reactant and the second reactant are mixed.Specifically, under the action of an external force, the first box body 11 moves away from the bottom cover 10 and forms a gap with the first chamber 101. This gap allows the second reactant in the top cover 12 to flow into the first chamber 101 and / or the first reactant in the first chamber 101 to flow out of the first chamber 101 and mix with the second reactant. It should be noted that although the first box body 11 moves away from the bottom cover 10, it is not completely separated from the bottom cover 10, that is, the first box body 11 still remains connected to the bottom cover 10. The first box body 11 forms a gap with the first chamber 101 under the action of an external force. In some embodiments, under the action of an external force, the first box body 11 is hung on the first chamber 101 of the bottom cover 10. That is, when the first box body 11 is subjected to an external force, although the first box body 11 will move relative to the bottom cover 10, the first box body 11 will not detach from the bottom cover 10 and still hangs on the bottom cover 10. This embodiment is applicable to the situation where it is necessary to detect the inside of the top cover after the reaction, preventing the first box body 11 from falling and affecting the identification of the reaction result of the first reactant and the second reactant or the identification of the reaction state after the reaction. For example, when it is necessary to detect the volatilization of chlorine dioxide gas or to perform turbidity detection on the reaction situation inside the top cover 12, it is ensured that the first box body 11 can hang in the original position without falling after being pushed open, avoiding affecting the accuracy of the turbidity sensor.

[0036] The first reactant and the second reactant can be any raw materials capable of preparing a gas 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 household appliance sterilization module 100 is activated, the solid or solid powder fills the first chamber 101 as much as possible or the liquid level of the second reactant reaches 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 by mixing; 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 first chamber 101 and mix with the second reactant. In other embodiments, both the first reactant and the second reactant can be liquids, as long as the two can 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 to prevent affecting the detection accuracy of the turbidity sensor 16 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 this substance is not limited, such as: solid and solid powder, liquid. In other embodiments, the first reactant is a peracid solution and the second reactant is a sodium chlorite aqueous solution, and these two liquid solutions react to produce chlorine dioxide gas. It should be noted that when the first reactant placed in the first chamber 101 is a liquid, preferably, the liquid fills the first chamber 101 to facilitate the mixing of the first reactant and the second reactant.

[0037] The volume of the first chamber 101 is at least 1 / 3 of the volume of the bottom cover 10. In order to prepare as many volatiles for disinfection as possible, the volume of the first chamber 101 can be at least more than one-half of the volume of the bottom cover 10, or the volume of the first chamber 101 is the volume of the bottom cover 10; in some embodiments, in addition to the first chamber 101, other accommodating chambers need to be provided on the bottom cover 10, and the accommodating chamber needs to be kept at a certain distance from the first chamber 101; specifically, in some embodiments, the volume of the first chamber 101 is between 1 / 3 and 1 / 2 of the volume of the bottom cover 10. On the one hand, it is to improve the amount of reactant raw materials as much as possible to facilitate the preparation of a larger amount of volatiles for sterilization; on the other hand, when there is a chamber for accommodating the turbidity sensor 16 on the bottom cover 10, preferably, there is a distance between the accommodating chamber where the turbidity sensor 16 is located and the first chamber 101, so that the turbidity sensor 16 is at the central position of the mixture of the first chamber 101 and another raw material, that is, the turbidity sensor 16 is as much as possible at the concentration-uniform position after the reaction mixture, ensuring the detection accuracy of the turbidity sensor 16.

[0038] A sealing portion 102 is also included near the first chamber 101. When the interference structure moves to the sealing portion 102, the sealing portion 102, the interference structure and the sealing component together form a sealed space to prevent the reactants in the household appliance sterilization module 100 from flowing out of the sealing portion. The interference structure is a structure for interfering with the first box body 11. In some embodiments, the interference structure is a top rod 15. In some embodiments, the bottom cover 10 further includes a sealing portion 102 for placing the ejector pin 15, and the sealing portion 102 is a movement space for the ejector pin 15; the sealing portion 102 is disposed near the first chamber 101, and after the ejector pin 15 moves in the sealing portion 102, it contacts the first box body 11 that seals the first chamber 101 and causes the first box body 11 to partially detach from the first chamber 101 (i.e., the first box body 11 still remains on the first chamber 101), so that the two reactants in an isolated state in the accommodating space are mixed with each other to generate volatiles for sterilization; at this time, the sealing portion 102, the ejector pin 15 and the sealing component (such as a sealing ring mounted on the ejector pin 15) together form a sealed space to prevent the raw materials for preparing volatiles or the volatiles or the products of the raw materials from flowing out of the sealing portion 102. 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, sleeve connection, screw connection, bonding, etc., that is, the fixed connection 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 home appliance sterilization module 100 can be ensured. The enclosed space formed by the bottom cover 10 and the first box body 11 is used to store the first reactant; the enclosed space formed by the first box body 11 and the top cover 12 is used to store the second reactant; the top rod 15 lifts the first box body 11 so that the first reactant and the second reactant are mixed to generate disinfection gas. In some embodiments, the push rod 15 moves a short distance and then lifts up the closed structure on the first chamber 101. The closed structure may be the first box body 11. The fixed connection method between the first box body 11 and the bottom cover 10 includes but is not limited to detachable connection methods such as snap-on, sleeve, screw, and cover. After the two are fixedly connected, a accommodating space for accommodating reactants is formed. The reactants may be solid or liquid. The sealing portion 102 is located near the first chamber 101, and the push rod 15 contacts the first box body 11 to lift the first box body 11 after moving a distance in the sealing portion 102; in some embodiments, the sealing portion 102 is arranged inside the first chamber 101 and a storage space for the first reactant is formed between the sealing portion 102 and the first chamber 101, and the sealing portion 102 extends along the extension direction of the first chamber 101 away from the box body 200. The shape and size of the sealing portion 102 are similar to those of the push rod 15. In the initial state, there is a gap between the end of the push rod 15 and the first box body 11, so that after the push rod 15 is subjected to external force, it can contact the first box body 11 after moving a small distance, and a gap is formed between the first box body 11 and the bottom cover 10.In some other embodiments, the sealing portion 102 is disposed at the outer peripheral edge of the first chamber 101 (not shown). The shape and size of the sealing portion 102 are approximately the same as those of the ejector rod 15, and the sealing portion 102 extends in the extending direction of the first chamber 101. Initially, there is a gap between the end of the ejector rod 15 and the outer contour of the first box body 11. After the ejector rod 15 is stressed, the end of the ejector rod 15 abuts against 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 stressed. In order to enable the ejector rod 15 to easily abut against and lift the first box body 11, at this time, a abutting portion matching the ejector rod 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 and the bottom cover 10 form a closed space initially. When an external force is applied, a gap is formed between the first box body 11 and the bottom cover 10 for the reaction fluid 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.

[0039] The size of the sealing portion needs to be able to accommodate the ejector rod 15. The end of the ejector rod 15 accommodated in the sealing portion is initially at a certain distance from the first box body 11. After the ejector rod 15 moves towards the first box body 11, the end of the ejector rod 15 abuts against the first box body 11 so that the first box body 11 is at least partially separated from the bottom cover 10. Initially, there is a gap between the end of the ejector rod 15 and the first box body 11, and this gap is generally set between 2 mm and 8 mm, so that after the ejector rod 15 is stressed, it can move a small distance to abut against the first box body 11 and form a gap between the first box body 11 and the bottom cover 10.

[0040] To ensure that the first box body 11 does not fall, the first box body 11 includes a first protrusion 111. The first protrusion 111 extends away from the household appliance inner container 200 or extends toward the household appliance inner container 200. Before and after the household appliance sterilization module 100 is enabled, the first protrusion 111 is hung on or sleeved on the sealing part 102. The opening size of the first protrusion 111 is larger than the opening size of the sealing part 102 and the first protrusion 111 can be of any shape, or the opening size of the first protrusion 111 is smaller than the opening size of the sealing part 102 and the first protrusion 111 can be of any shape. In some embodiments, the first protrusion 111 extends away from the household appliance inner container 200. At this time, the opening of the first protrusion 111 is larger than the opening of the sealing part 102, and the first protrusion 111 is initially hung on the sealing part 102. In some other embodiments, the first protrusion 111 extends toward the household appliance inner container 200. At this time, the opening of the first protrusion 111 is smaller than the opening of the sealing part 102, and the first protrusion 111 is initially sleeved on the sealing part 102. When the first box body 11 is stressed, the first box body 11 is lifted up. However, due to the existence of the first protrusion 111, the first box body 11 can still remain on the bottom cover 10 without falling. At this time, since there is a gap between the first box body 11 and the bottom cover 10, the reactants can slowly react through this gap; or when the household appliance sterilization module includes a turbidity sensor 16, it can prevent the first box body 11 from falling and affecting the detection accuracy of the turbidity sensor.

[0041] 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 arranged on the bottom cover 10. Initially, the flip structure is sealed with the bottom cover 10. After the ejector rod 15 lifts up the flip structure, the second reactant is mixed with the first reactant.

[0042] The side of the bottom cover 10 close to the household appliance inner container 200 includes a second chamber 103. The second chamber 103 is a depression extending from the bottom cover 10 toward the household appliance inner container 200 or away from the household appliance inner container 200 to form a chamber for accommodating the turbidity sensor 16. The turbidity sensor 16 is plugged into the plug-in wire terminal on the inner container 200; at least the second chamber 103 of the bottom cover 10 is made of a transparent material so that the turbidity sensor 16 can detect the color change in the accommodation space through the second chamber 103 to obtain the change in the remaining amount of the volatile matter in the household appliance sterilization module 100.

[0043] In order to ensure the detection accuracy of the turbidity sensor 16 and ensure that the turbidity sensor 16 maximizes contact with the volatiles in the accommodation space, the second chamber 103 is preferably set as a depression extending from the bottom cover 10 to the side away from the home appliance inner tank 200. At this time, the second chamber 103 is in the accommodation space formed by the bottom cover 10 and the top cover 12, that is, the substances in the accommodation space are arranged around the turbidity sensor 16 to ensure that the turbidity sensor 16 quickly detects the color change in the accommodation space. When the accommodation space contains chlorine dioxide gas, a volatile substance used for sterilization, the chlorine dioxide gas needs to be loaded in a gel-like substance. At this time, the turbidity sensor 16 detects the color change of the gel in the accommodation space to obtain the residual amount of chlorine dioxide gas; when the accommodation space contains raw materials for preparing volatiles, the turbidity sensor 16 detects the color change of the liquid or gel in the accommodation space to obtain the residual amount of volatiles.

[0044] For the convenience of processing, the bottom cover 10 can be directly made of a transparent material, so that the turbidity sensor 16 can detect the color change in the accommodating space.

[0045] Before the home appliance sterilization module 100 is used, the second reactant in the top cover 12 is a colorless transparent liquid. When the top rod 15 pushes open the first box body 11, the first reactant and the second reactant are mixed to form a colored liquid or gel in the home appliance sterilization module 100. As the chlorine dioxide gas continues to volatilize, the color gradually fades. At this time, by using the turbidity sensor to detect the color change in the transparent top cover 12, the data is transmitted to the main control board, so as to timely understand the remaining amount of the home appliance sterilization module 100 in the home appliance box, facilitate timely replacement, and maintain a good storage environment in the home appliance box. In order to prevent other factors from infecting the measurement accuracy of the turbidity sensor, when the first box body 11 is pushed open, the first box body 11 is hung on the bottom cover 10 and will not fall, so as to avoid affecting the accuracy of the turbidity sensor.

[0046] Embodiment 2

[0047] like Figures 1-5 As shown, a household appliance sterilization module 100 is installed on the inner shell of the household appliance box. Specifically, it can be installed at any position of the inner shell. Preferably, in order to facilitate the gas used for disinfection to flow in the household appliance box as soon as possible, the household appliance sterilization module is arranged in the air outlet area of ​​the air duct. The household appliance sterilization module includes the installation structure for the household appliance sterilization module in the above embodiment, and also includes: a top cover 12, and a storage space for accommodating the second reactant is formed between the top cover 12 and the first box body 11; after the household appliance sterilization module 100 is activated, the volatiles enter the household appliance box through the vents on the household appliance sterilization module 100. The vents can be set at any position of the household appliance sterilization module 100 away from its installation surface, and the number and shape of the vents can also be set according to actual needs; preferably, the vents are set on the top cover 12 for easy processing.

[0048] When the second reactant is a liquid, to ensure that the first cartridge 11 can be at least partially separated from the bottom cover 10 and the second reactant can easily flow into the first chamber 101, the liquid level of the second reactant in the top cover 12 is at least above the outer contour of the first cartridge 11. So that after the first cartridge 11 is at least partially separated from the bottom cover 10, the second reactant can enter the sealed space formed by the first cartridge 11 and the bottom cover 10. In some embodiments, when the household appliance sterilization module 100 is placed vertically, since the first reactant is in the sealed space formed by the first cartridge 11, the first chamber 101, and the sealing portion 102, therefore, the liquid level of the second reactant is at least above the position where the bottom of the outer contour of the first cartridge 11 is located. Preferably, the liquid level of the second reactant is above the position where the top of the outer contour of the first cartridge 11 is located to ensure that the second reactant and the first reactant can be easily and fully mixed. In other embodiments, when the household appliance sterilization module 100 is horizontally suspended at the top of the inner tank, the liquid level of the second reactant is at least above the position where the entire outer contour of the first cartridge 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.

[0049] To control the air permeability of the volatiles in the household appliance sterilization module 100, it further includes a breathable membrane 13, and the breathable membrane 13 is hermetically covered above the ventilation area of the top cover 12; specifically, the breathable membrane 13 is hermetically covered on the ventilation holes of the top cover 12 along the contour of the top cover 12, and the ventilation holes can be set in any shape and at any position; the breathable membrane 13 is arranged along the contour of the top cover 12 to ensure the sealing between the breathable membrane 13 and the top cover 12 and prevent gaps between the breathable membrane 13 and the top cover 12, resulting in volatiles entering the household appliance inner tank without passing through the breathable membrane 13. The breathable membrane 13 is made of a material that is breathable but not permeable to water to prevent the reactant and / or the reaction product from flowing out. In this embodiment, it is easy to process and can ensure breathability and water impermeability. Since the breathable membrane is relatively soft and easily damaged, in some embodiments, it further includes a second cartridge 14, and the second cartridge 14 presses the breathable membrane 13 onto the top cover 12. At this time, the second cartridge 14 forms a consistent overall contour with the top cover 12 and the bottom cover 10, which can ensure the integrity and aesthetics of the household appliance sterilization module; in addition, the second cartridge 14 presses the breathable membrane 13 onto the top cover 12, which can prevent the sealing performance of the breathable membrane 13 from decreasing after long-term use and forming gaps with the top cover 12. The second cartridge 14 also includes a number of ventilation holes to facilitate the entry of gas into the household appliance box body.

[0050] The breathable film 13 is made of a material that is breathable but not water-permeable. It can be a breathable film (such as a PE film, a PUW film, etc.), silicone, non-woven fabric, etc. On the one hand, it can facilitate the passage of the volatiles in the form of gas, and on the other hand, it can block the overflow of liquid from the household appliance sterilization module 100. In addition, the breathable film 13 can prevent dust outside the sterilization module 100 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 amount of volatiles that can pass through in the same period of time.

[0051] The present invention also relates to a refrigerator, which includes a box body and a door body. The inner liner 200 of the box body includes the household appliance sterilization module 100 as described in the above embodiments to sterilize the interior of the household appliance box.
