Detailed implementation manners

[0040] 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.

[0041] Embodiment 1

[0042] As Figure 1-6 shown, a household appliance sterilization module 100 is fixedly installed in a household appliance box body; the sterilization module is used to sterilize the inside of the household appliance box body, and the household appliance is a household appliance such as a refrigerator, a refrigerator, etc. that needs to maintain a good storage environment. The fixed installation methods include common fixed installation methods in the art such as pasting, snap connection, screw connection, etc. The household appliance sterilization module 100 includes: a sterilization module body 1, which can be set in any shape, and its surface includes a breathable part formed by a plurality of first ventilation holes 112, so that the volatiles for sterilization in the sterilization module body 1 overflow through the first ventilation holes 112; a breathable film 13, which is used to adjust the breathable amount of the volatiles, and is hermetically covered on the breathable part; in some embodiments, the breathable film 13 can be hermetically covered on the breathable part along the contour of the breathable part on the sterilization module body 1 to control the breathable amount of the volatiles; the volatiles enter the household appliance box body after passing through the breathable part and entering the breathable film 13 to sterilize the inside of the household appliance box body.

[0043] The breathable film 13 is made of a material that is breathable but not water-permeable, which 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.

[0044] In some embodiments, the household appliance selects breathable films 13 with different breathable rates according to the volume of its cabinet; the volatiles have different amounts of gas passing through breathable films 13 with different breathable rates in the same period of time, so as to change the breathable rate of the household appliance sterilization module 100.

[0045] In order to install household appliance sterilization modules 100 with different disinfection gas breathable rates in household appliances of different volumes, breathable films 13 with different breathable rates can be provided for different types of household appliances. The breathable film 13 can be a breathable film, plastic, etc. Preferably, the breathable film 13 is preferably plastic so that it is not easily damaged during transportation or storage.

[0046] In some embodiments, the sterilization module body 1 includes a bottom cover 10 and a top cover 12. The bottom cover 10 and the top cover 12 are fixedly connected (such as: ultrasonic welding, snap connection, socket connection, screw connection, etc.) to form a containing space for the volatiles. In order to facilitate the substances in the container to enter the inner liner 200 of the cabinet from the sterilization module body 1, a number of first ventilation holes 112 are included on the bottom cover 10 and / or the top cover 12, and the first ventilation holes 112 can be set in any shape. When the bottom cover 10 is fixedly installed on the inner liner 200 of the household appliance, the top cover 12 faces the inside of the inner liner 200. At this time, a number of first ventilation holes 112 can be provided on the top cover 12, and specifically, the number of the first ventilation holes 112 can be controlled according to the predicted breathable rate. In order to further control the breathable rate of the volatiles, the breathable film 13 is included, and the breathable film 13 covers the side of the top cover 12 where the first ventilation holes 112 are located along the contour of the top cover 12, so that the volatiles enter the inner liner 200 after passing through the breathable film 13.

[0047] In some embodiments, in order to prevent the breathable film from being damaged after long-term use and to ensure the sealing performance between the breathable film and the top cover 12, a first outer cover 14 with a number of second ventilation holes 141 is further included. The first outer cover 14 presses the breathable film 13 onto the top cover 12. At this time, the first outer cover 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 first outer cover 14 presses the breathable film 13 onto the top cover 12, which can prevent the sealing performance of the breathable film 13 from decreasing after long-term use and forming a gap with the top cover 12. A number of ventilation holes are also included on the first outer cover 14 to facilitate the entry of gas into the household appliance cabinet.

[0048] In order to adjust the air permeability of the volatile matter according to requirements, in some embodiments, it further includes an insertion piece (not shown), which is movably inserted between the air-permeable membrane 13 and the first outer cover 14. After being driven by an external force, the insertion piece can move relative to the air-permeable membrane 13 to block part of the volatile matter from entering the inner cavity of the home appliance through the second ventilation holes 141 on the first outer cover 14, that is, to change the air permeability of the volatile matter. When the user needs to increase the air permeability of the volatile matter, the insertion piece is driven to move away from the center position of the home appliance sterilization module 100; when the user needs to reduce the air permeability of the volatile matter, the insertion piece is driven to move closer to the center position of the home appliance sterilization module 100.

[0049] In order to adjust the air permeability of the volatile matter according to requirements, in some embodiments, it further includes a second outer cover integrally formed with the first outer cover 14. The second outer cover includes a number of third ventilation holes, and the second outer cover can rotate relative to the first outer cover 14 to change the overlapping area between the second ventilation holes 141 and the third ventilation holes. Specifically, it further includes a second outer cover (not shown), which includes a number of third ventilation holes, and the second outer cover can rotate relative to the first outer cover 14 to change the overlapping area between the second ventilation holes 141 and the third ventilation holes, so as to change the air permeability of the disinfection gas in the same time period. In some embodiments, the second outer cover is disposed between the first outer cover 14 and the sterilization module body 1. The second outer cover is provided with a number of third ventilation holes. The third ventilation holes on the third outer cover can be disposed at any position on the third outer cover, and can be of any shape and any number. The first outer cover 14 is attached to the second outer cover and can rotate relative to the second outer cover. At this time, the second ventilation holes 141 on the first outer cover 14 move relative to the third ventilation holes on the second outer cover to form ventilation holes with different overlapping areas, and the ventilation holes with different overlapping areas can pass different amounts of disinfection gas. In other embodiments, the second outer cover can be disposed on the side of the first outer cover 14 away from the sterilization module body 1. At this time, the second outer cover is provided with a number of third ventilation holes. The third ventilation holes on the third outer cover can be disposed at any position on the third outer cover, and can be of any shape and any number. The second outer cover is attached to the first outer cover 14 and can rotate relative to the first outer cover 14. At this time, the third ventilation holes on the second outer cover move relative to the second ventilation holes 141 on the first outer cover 14 to form ventilation holes with different overlapping areas, and the ventilation holes with different overlapping areas can pass different amounts of disinfection gas.

[0050] The volatile matter in the sterilization module body 1 is a finished product or is prepared on-site. Specifically, the sterilization module body 1 can be used to directly store disinfection gas. However, due to the limited internal space, the amount of disinfection gas that can be stored is limited. If the household appliance sterilization module 100 is used, it needs to be frequently replaced in a short period, which affects the user experience. At this time, the disinfection gas can be chlorine dioxide or ozone. In order to obtain a household appliance sterilization module 100 with a longer service life to improve the user experience, the sterilization module body 1 can be used to store the raw materials for preparing disinfection gas. When the household appliance sterilization module 100 needs to be used, the raw materials for preparing disinfection gas are triggered to react to prepare a large amount of disinfection gas.

[0051] In some embodiments, the sterilization module body 1 can be partially made of a breathable membrane during the original processing. Although this will make the processing process more cumbersome, it solves the problem of the sealing performance of the breathable membrane and the ventilation part where the first ventilation hole 112 is located.

[0052] When the home appliance sterilization module 100 selects to prepare the sterilization gas on site to obtain a large amount of sterilization gas, the sterilization module body 1 includes: a bottom cover 10, the bottom cover 10 includes a first chamber 101 for storing the first reactant on the side away from the home appliance inner tank 200; 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 home appliance box inner tank 200; the bottom cover 10 is fixedly connected to the top cover 12, and a receiving cavity is formed between the bottom cover 10 and the top cover 12 to accommodate the reactant. The first box body 11 is used to encapsulate the first reactant in the first chamber 101; the top cover 12 is fixedly connected to the bottom cover 10, and a storage space for storing the second reactant is formed between the top cover 12 and the first box body 11; under the action of external force, the first box body 11 is at least partially separated from the bottom cover 10, so that the two reactants in an isolated state in the home appliance sterilization module 100 are mixed with each other to generate volatiles for sterilization. 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 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 home appliance sterilization module 100 can be ensured; 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 101, so that the first reactant and the second reactant do not circulate before the home appliance sterilization module 100 is activated. The first box body 11 can initially cover or sleeve the bottom cover 10 or the first box body 11 is a flip structure or a hinge structure; under the action of external force, the first box body 11 at least partially separates from the bottom cover 10, so that the first reactant and the second reactant are mixed, and the volatile substances generated for disinfection flow out from the breathable part on the sterilization module body 1. The external force can be provided by the user or by an external force, that is, the top rod 15 contacts the first box body and causes the first box body 11 to be partially separated from the bottom cover 10. At this time, the first box body 11 does not fall (hangs on the first chamber 101), and will not affect the detection instrument to detect the reactant product (such as the color of chlorine dioxide gas) in the sterilization module body 1; if no detection is required, the first box body 11 can be completely separated from the bottom cover 10. Since the disinfectant in the household appliance sterilization module 100 is a gas, at this time, the top cover 12 includes a ventilated portion, which can be set to any shape and any position. In some embodiments, the ventilated portion is a ventilated membrane 13; in other embodiments, the top cover 12 includes a plurality of first vents 112, which can be set to any shape and any position. The first vent 112 includes a ventilated membrane outside, and the ventilated membrane seals the area where the first vent 112 on the top cover 12 is located to prevent the reactant and / or the reactant product from flowing out.

[0053] When the disinfecting gas is the disinfecting gas of the finished product, the sterilization module body 1 also includes a breathable area and a sealing layer (not shown), and the sealing layer is covered on the breathable area when the household appliance sterilization module 100 is not enabled. That is, if the disinfecting gas is the disinfecting gas of the finished product, the sterilization module body 1 is not breathable before it is enabled, but after it is enabled, a breathable area is required to allow the disinfecting gas to enter the household 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 uncovered or punctured before use, or the sealing layer is a cover body covered on the breathable part. When it is needed, the sealing layer can be disassembled. The vent can also be a breathable membrane. 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 household appliance box can be improved.

[0054] If the disinfection gas is prepared on-site in real time, the sterilization module body 1 includes at least two independent spaces for storing the raw materials of the disinfection gas reaction. In some embodiments, if chlorine dioxide gas is prepared on-site, the sterilization module body 1 includes two independent spaces for storing raw materials or other materials. For example, when two independent spaces are included, one space is used to store the first reactant and the other space is used to store the second reactant; such as one space stores an acidic liquid, such as hypochlorous acid and / or hydrochloric acid, etc., and the second space stores a solid powder, and the fixed powder is generally a chlorate or chlorite powder; it should be understood that the acidic liquid can be set in the second space and the solid powder can be set in the first space. It should be understood that the substances stored in the first space and the second space can be any substance that can generate chlorine dioxide in combination, and the state of the substance is not limited. For example, chlorine dioxide gas can be produced by reacting an acid solution with an aqueous solution of sodium chlorite.

[0055] It should be noted that when preparing disinfectant gas, the prepared disinfectant 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 preparing disinfectant gas in this embodiment, the disinfectant gas refers to chlorine dioxide gas.

[0056] 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 on 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.

[0057] In some embodiments, a boss (not shown) is included in the sealing portion 102. The boss extends along the inner wall of the sealing portion 102 towards the center of the ejector rod 15 to form a sealing portion 102 with a smaller diameter in the sealing portion 102 to accommodate the main body portion of the ejector rod 15. At this time, the end of the ejector rod 15 can be located at the entrance of the sealing portion 102 or inside the sealing portion. When the end of the ejector rod 15 is located at the entrance of the sealing portion 102, the end of the ejector rod 15 and the contour of the bottom cover 10 form an integral contour. When the end of the ejector rod 15 is located inside the sealing portion 102 and the boss is included in the sealing portion 102, the end of the ejector rod 15 abuts against the boss to provide support for the ejector rod 15. At the same time, the boss can prevent the ejector rod 15 from moving excessively so that the first box body 11 is completely separated from the bottom cover 10.

[0058] The bottom cover 10 includes a sealing portion 102 for accommodating the ejector rod 15. At this time, the ejector rod 15 is directly assembled on the bottom cover 10, and the ejector rod 15 moves within the sealing portion 102 so that the first box body 11 is partially separated from the bottom cover 10; 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 manner between the top cover 12 and the bottom cover 10 includes detachable connection and non-detachable connection. When non-detachable connection is adopted, the sealing performance of the household appliance sterilization module 100 can be ensured. The closed space formed by the bottom cover 10 and the first box body 11 is used to store the first reactant, and the first reactant is a solid or a liquid; the closed space formed by the first box body 11 and the top cover 12 is used to store the second reactant, and the second reactant is a liquid or a solid powder; the ejector rod 15 jacks up the first box body 11 so that the first reactant and the second reactant are mixed to generate a disinfection gas. In other embodiments, the bottom cover 10 only includes a sealing portion 102. At this time, a boss is assembled on the inner liner of the household appliance, and the boss can move within the sealing portion 102 so that the first box body 11 is partially separated from the bottom cover 10.

[0059] In some embodiments, there is a gap between the first box body 11 and the end of the device for driving the first box body 11 before the household appliance sterilization module is enabled. Specifically, there is a gap between the first box body 11 and the ejector rod 15 for driving the first box body 11, that is, after the ejector rod 15 receives a driving force and moves a certain distance, the end of the ejector rod 15 will contact the first box body 11 so that the first box body 11 is partially separated from the bottom cover 10 to facilitate the mixing of the two reactants; this gap gives the ejector rod 15 a corresponding buffer space to prevent the household appliance sterilization module 100 from being accidentally collided and triggering the first box body 11 to be jacked up. It should be understood that the end of the ejector rod 15 can contact the first box body 11 initially but the contact force is not sufficient to cause the first box body 11 to be completely separated from the bottom cover 10. However, in order to prevent the first box body 11 from being completely separated from the bottom cover 10 due to the shaking of the household appliance sterilization module 100 during transportation, preferably, there is a gap between the ejector rod 15 and the first box body 11.

[0060] To ensure that the first box body 11 does not fall, the first box body 11 includes a protrusion 111. The protrusion 111 extends away from the home appliance inner container 200 or towards the home appliance inner container 200. Before and after the home appliance sterilization module 100 is enabled, the protrusion 111 is hung on or sleeved on the sealing part 102. The opening size of the protrusion 111 is larger than the opening size of the sealing part 102 and the protrusion 111 can be of any shape, or the opening size of the protrusion 111 is smaller than the opening size of the sealing part 102 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 sealing part 102, and the protrusion 111 is initially hung on the sealing part 102. 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 sealing part 102, and the 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, but due to the existence of the protrusion 111, the first box body 11 can still remain on the bottom cover 10 without falling. At this time, a gap is formed between the first box body 11 and the bottom cover 10, facilitating the slow reaction of the reactants. In addition, when including the turbidity sensor 16, the first box body 11 remains on the bottom cover 10, which can prevent its fall from affecting the detection accuracy of the turbidity sensor 16.

[0061] To prevent the disinfection gas in the home appliance sterilization module 100 from remaining in the home appliance box body after it is used up, there is an urgent need for an indication of the remaining amount of the disinfection gas in the home appliance sterilization module 100. In some embodiments, the bottom cover 10 further includes a second chamber 103 near the home appliance inner container 200, and at least the second chamber 103 is made of a transparent material. The second chamber 103 is used to accommodate the turbidity sensor. The shape and size of the second chamber 103 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 103.

[0062] To ensure the detection accuracy of the turbidity sensor 16 and ensure that the turbidity sensor 16 maximally contacts the volatiles in the accommodation space, the second chamber 103 is preferably set as a depression extending away from the home appliance inner container 200 from the bottom cover 10. 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 substance in the accommodation space is the volatile chlorine dioxide gas for sterilization, the chlorine dioxide gas needs to be loaded in a gel-like substance. At this time, the remaining amount of the chlorine dioxide gas is obtained by detecting the color change of the gel in the accommodation space through the turbidity sensor 16. When the substance in the accommodation space is the raw material for preparing the volatile, the remaining amount of the volatile is obtained by detecting the color change of the liquid or gel in the accommodation space through the turbidity sensor 16.

[0063] For convenient processing, the bottom cover 10 can be directly made of a transparent material to facilitate the turbidity sensor 16 to detect the color change in the accommodation space.

[0064] The bottom cover 10 is fixedly connected to the top cover 12, and an accommodation cavity is formed between the bottom cover 10 and the top cover 12 to accommodate the reactants. Before the first reactant and the second reactant are mixed, the second reactant is stored in the top cover 12. The second reactant and the first reactant are separated in two independent spaces by an isolation structure (such as by separately providing a first box body 11 covering the first chamber 101); the second chamber 103 is arranged away from the first chamber 101 so that when the second reactant and the first reactant are mixed, the turbidity sensor 16 is in a region with uniform concentration of the mixed reactants; specifically, since the turbidity sensor 16 is arranged away from the first chamber 101 where the first reactant is stored, after the second reactant and the first reactant are mixed, the color in the first chamber 101 and near the first chamber 101 is darker (higher concentration of volatile substances), while the color away from the first chamber 101 is lighter (lower concentration of volatile substances); when the volatile substances volatilize for a period of time, the concentration of the volatile substances tends to be balanced, that is, the color in the accommodation cavity tends to be consistent. Therefore, in order to ensure the accuracy of the measured concentration of the disinfection gas, the turbidity sensor 16 is arranged away from the first chamber 101.

[0065] The first reactant and the second reactant can be any raw materials capable of preparing the 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 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 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 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 to prevent affecting the detection accuracy of the turbidity sensor 16 when the turbidity sensor 16 is included.

[0066] It should be understood that the disinfection gas in this embodiment is a gas with an obvious color, such as chlorine dioxide gas. The chlorine dioxide gas is dispersed in a gel-like substance. As the chlorine dioxide gas volatilizes, the color of the gel will change, and the turbidity sensor is used to detect the color change of the gel to reflect the remaining amount of the chlorine dioxide gas.

[0068] As Figure 1-6 shown, a refrigerator includes a box body and a door body; it further includes the sterilization module body 1 in the above embodiment, and the sterilization module body 1 is installed in the inner liner 200 of the refrigerator box body. Specifically, the sterilization module body 1 is generally installed around the inner liner 200 or on the top of the inner liner 200. If it is set below the inner liner 200, since the density of the disinfection gas is generally greater than that of air, it is not convenient for the disinfection gas to fill the entire box body.
