Example one

As shown in fig. 1 to 8, a sterilization module 100 for a refrigerator includes a sterilization apparatus body fixedly installed in an inner container 200 of the refrigerator; specifically, the sterilization device body is adhered, clamped and screwed to the inner container 200 of the refrigerator. The conventional sterilization module 100 directly stores the volatile substances for sterilization, but because the storage space of the sterilization module 100 is limited, the conventional sterilization module can only store a small amount of volatile substances and needs to be replaced for a long time, and therefore, a sterilization device body capable of preparing the volatile substances for sterilization on site needs to be provided to obtain a large amount of volatile substances for sterilization in a limited space. The sterilization device body comprises: the box body is internally provided with a containing space for sterilizing substance reactants, and the box body is provided with a plurality of vent holes so that sterilizing volatile matters can enter the refrigerator body through the vent holes; the isolation structure is assembled in the accommodating space of the box body and forms an isolation area, and the isolation area forms at least two independent spaces for storing reactants of the sterilizing substances in the accommodating space; after the main body of the sterilization device is activated, the isolation structure is at least partially separated from the isolation area, so that at least two reactants in the isolation state in the sterilization module 100 are mixed with each other to generate volatile matters for sterilization, and the volatile matters enter the refrigerator inner container 200 from the ventilation position on the box body. In some embodiments, the isolation structure is a membrane structure, the membrane structure forms two independent chambers in the accommodating space, and when the sterilization device body needs to be used, the membrane structure is punctured by an external force, so that the reactants in the two independent chambers are mixed with each other to generate the volatile matter for sterilization. In some embodiments, the isolation structure is a plate-shaped structure, the plate-shaped structure forms two independent chambers in the accommodating space, and after the isolation structure is subjected to an external force, the isolation structure moves relative to the accommodating space so that the isolation structure is at least partially separated from the isolation region before activation; in other embodiments, the isolation structure is a flip structure installed in the accommodating space, and after an external force is applied, the isolation structure is still partially hung in the isolation region before activation.

In some embodiments, the case body is formed by assembling (e.g. ultrasonic welding, clamping, sleeving, screwing, etc.) the bottom cover 10 and the top cover 12, and a corresponding accommodating space for storing the sterilizing volatile is formed between the bottom cover 10 and the top cover 12; at this time, the isolation structure is disposed in the accommodating space to form an independent chamber for storing the reactant. In order to further enhance the sealing performance of the reactant before the sterilization module is not used, the side of the bottom cover 10 facing away from the refrigerator inner container 200 comprises a first chamber 103 for storing the first reactant, the first chamber 103 has a certain depth for storing the first reactant, the first chamber 103 can be set to be any shape, and in some embodiments, the first chamber 103 extends to the side facing away from the refrigerator inner container 200; the isolation structure encapsulates the first reactant in the first chamber 103, and the isolation structure and the top cover 12 together form a containing space for the second reactant; in some embodiments, the isolation structure is the first container 11, so that the first reactant and the second reactant do not flow before the refrigerator sterilization module 100 is not activated, and the first container 11 may be initially covered or sleeved on the bottom cover 10 or the first container 11 is in a flip structure or a hinge structure; under the action of external force, the first container 11 is at least partially separated from the bottom cover 10, so that the first reactant and the second reactant are mixed, and volatile substances for disinfection are generated and flow out from the ventilation part on the sterilization module body 1. The external force can be provided by a user or provided by the external force, that is, the top rod 15 contacts the first box body 11 and partially separates the first box body 11 from the bottom cover 10, and at this time, the first box body 11 does not fall (hang on the first chamber 103), and the detection instrument cannot be influenced to detect the reactant product (such as the color of chlorine dioxide gas) in the sterilization module body 1; if the detection is not required, the first container 11 can be completely separated from the bottom cover 10.

In some embodiments, the first chamber 103 has a volumetric size of at least 1/3 of the volumetric size of the bottom lid 10. In order to prepare as much volatile for sterilization as possible, the volume of the first chamber 103 may be at least one-half of the volume of the bottom cap 10, or the volume of the first chamber 103 is the volume of the bottom cap 10; in some embodiments, in addition to the first cavity 103, another accommodating cavity needs to be provided on the bottom cover 10, and the accommodating cavity needs to be kept a certain distance from the first cavity 103; in particular, in some embodiments, the first chamber 103 has a volume size between 1/3 and 1/2 of the volume size of the bottom cover 10, on the one hand to increase the amount of reactant materials as much as possible, so as to facilitate the preparation of a larger amount of volatile for sterilization; on the other hand, when the bottom cover 10 includes a chamber for accommodating the turbidity sensor 16, it is preferable that the accommodating cavity for accommodating the turbidity sensor 16 is spaced from the first chamber 103, so that the turbidity sensor 16 is located at the central position where the first chamber 103 is mixed with another raw material, that is, the turbidity sensor 16 is located at a position where the concentration of the mixed reactant is uniform as much as possible, thereby ensuring the detection accuracy of the turbidity sensor 16.

In some embodiments, a sealing portion 102 is further included to form a movement space of the jack 15; the sealing portion 102 is disposed near the first chamber 103, such that the sealing portion 102, the rod 102 and a sealing member (e.g., a sealing gasket sleeved on the rod 15) form a sealing space together; in addition, the push rod 15 abuts against the first container 11 after moving a distance in the sealing part 102 so that the first container 11 is at least partially separated from the bottom cover 10. The sealing portion 102 is used for accommodating the push rod 15, that is, the size of the sealing portion 102 needs to be able to accommodate the push rod 15, the end portion of the push rod 15 accommodated in the sealing portion 102 keeps a distance from the first box body 11 in an initial state, and after the push rod 15 moves towards the direction of the first box body 11, the tail end of the push rod 15 abuts against the first box body 11 so that the first box body 11 generates a gap relative to the bottom cover 10 or the push rod abuts against the first box body 11 and then the first box body 11 falls. In some embodiments, the sealing portion 102 is disposed in the first chamber 103, and a space for accommodating the first reactant is formed between the sealing portion 102 and the first chamber 103, the sealing portion 102 extends along the extending direction of the first chamber 103 to the side away from the tank liner 200, and the sealing portion 102, the rod 15, and the sealing member (e.g., a sealing gasket sleeved on the rod 15) together form a sealing space to prevent the reactant from flowing out of the sealing portion 102. The shape and size of the sealing part 102 are similar to those of the top rod 15, and a gap is formed between the end of the top rod 15 and the first box body 11 in the initial state, the gap is generally set between 2mm and 8mm, so that the top rod 15 can abut against the first box body 11 after moving for a small distance after receiving an external force, and a gap is formed between the first box body 11 and the bottom cover 10. In other embodiments, the sealing portion 102 is disposed at the peripheral edge (not shown) of the first chamber 103, the shape and size of the sealing portion 102 are similar to the shape and size of the rod 15, and the sealing portion 102 extends toward the extending direction of the first chamber 103; the end of the top bar 15 has a gap with the outer contour of the first container 11 initially, and after the top bar 15 is stressed, the end of the top bar 15 abuts against the outer contour of the first container 11, so that the first container 11 is partially separated from the bottom cover 10 after being stressed. In order to make the top rod 15 easily contact with and lift up the first box 11, at this time, a contact part matching with the top rod 15 may be disposed on the outer contour of the first box 11, so as to lift up the first box 11. In addition, the first container 11 can be a hinge structure or a flip structure, so that the first container 11 initially forms a closed space with the bottom cover 10, when an external force is applied, the first container 11 and the bottom cover 10 form a gap for the reactants to flow in or out, and at this time, the first container 11 is kept on the bottom cover 10, and the measurement accuracy of the turbidity sensor 16 cannot be affected by the falling.

In order to ensure that the first container 11 does not fall, the isolation structure includes a first protrusion 111 protruding from the isolation structure, and the first protrusion 111 is still retained on the first cavity 103 of the bottom cover 10 after the sterilization module 100 is activated. Specifically, the first box 11 includes a first protrusion 111 thereon, the first protrusion 111 extends toward a side away from the refrigerator liner 200 or extends toward a side close to the refrigerator liner 200, and the first protrusion 111 is hung on or sleeved on the sealing portion 102 before and after the refrigerator sterilization module 100 is used. The opening size of the first protrusion 111 is larger than the opening size of the sealing part 102 and the first protrusion 111 may be in 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 may be in any shape. In some embodiments, the first protrusion 111 extends to the side away from the refrigerator 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 other embodiments, the first protrusion 111 extends toward the side close to the refrigerator inner container 200, at this time, the opening of the first protrusion 111 is smaller than the opening of the sealing portion 102, and the first protrusion 111 is initially sleeved on the sealing portion 102. When the first container 11 is forced, the first container 11 is lifted, but the first container 11 is still maintained on the bottom cover 10 without falling down due to the first protrusion 111.

In order to prevent the movement range of the push rod 15 from exceeding the preset range, a second protrusion (not shown) is further included in the sealing portion 102, and the second protrusion extends along the inner wall of the sealing portion 102 toward the center of the push rod 15, so that the end of the push rod 15 abuts against the second protrusion. The end of the jack 15 can be located at the entrance of the sealing part 102 or in the sealing part, when the end of the jack 15 is located at the entrance of the sealing part 102, the end of the jack 15 forms an integral contour with the contour of the bottom cover 10; when the end of the push rod 15 is located in the sealing portion 102 and the sealing portion 102 includes the second protrusion, the end of the push rod 15 abuts against the second protrusion to provide support for the push rod 15, and at the same time, the second protrusion can prevent the push rod 15 from moving excessively so that (when the bottom cover 10 includes the turbidity sensor, the first container 11 may cause an error in the detection accuracy of the turbidity sensor if the first container 11 is separated from the bottom cover 10) the first container 11 is completely separated from the bottom cover 10.

In order to detect the remaining amount of the sterilization module 100 and prevent the sterilization module 100 from being used after being expired, the sterilization module 100 further includes a turbidity sensor 16 fixedly mounted on the bottom cover 10 or outside the bottom cover 10 to detect a color change in the receiving space through a transparent area on the bottom cover 10. Specifically, at least a portion of the bottom cover 10 is made of a transparent material to facilitate detection within the sterilization module 100 by the turbidity sensor 16 through the transparent portion on the bottom cover 10. In some embodiments, the turbidity sensor 16 is fixedly mounted outside the bottom cover 10; in other embodiments, the turbidity sensor 16 is fixed directly to the bottom cover 10. For example, the bottom cap 10 may further include a chamber for receiving the turbidity sensor 16; in order not to affect the accommodating space, the chamber may extend from the surface of the bottom cover 10 to a position far away from the inside of the accommodating space, and at this time, the turbidity sensor 16 is bonded or fixed to the chamber through other fixing structures; in other embodiments, the chamber is recessed from the surface of the bottom cap 10 into the interior of the bottom cap 10 so that the turbidity sensor 16 is surrounded by the sterilizing substance; at this time, the chamber is located in the accommodating space, and although the chamber occupies a certain space of the accommodating space, the turbidity sensor 16 is surrounded by the object to be detected in the accommodating space, so that the detection precision of the turbidity sensor 16 can be improved; in addition, since the chamber is formed by recessing the bottom cover 10, the turbidity sensor 16 can be directly placed in the chamber for fixing without any other fixing structure.

In order to prevent the sterilizing gas in the refrigerator sterilization module 100 from remaining in the refrigerator after the sterilizing gas is used up, it is necessary to indicate the remaining amount of the sterilizing gas in the sterilization module 100. In some embodiments, the bottom cover 10 further includes a second chamber 101 on a side close to the inner container 200, and at least the second chamber 101 is made of a transparent material, and the second chamber 101 is used for accommodating the turbidity sensor. The second chamber 101 is shaped and sized 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.

In order to ensure the detection accuracy of the turbidity sensor 16 and ensure that the turbidity sensor 16 maximally contacts the volatile in the accommodating space, the second chamber 101 is preferably configured as a recess extending from the bottom cover 10 to the side away from the refrigerator inner container 200 (the second chamber 101 is recessed from the bottom cover 10 to the direction close to the top cover 12), at this time, the second chamber 101 is located in the accommodating space formed by the bottom cover 10 and the top cover 12, that is, the substance in the accommodating space is set around the turbidity sensor 16, so as to ensure that the turbidity sensor 16 rapidly detects the color change in the accommodating space. When volatile chlorine dioxide gas for sterilization is contained in the containing space, the chlorine dioxide gas needs to be loaded in the gel substances, and at the moment, the turbidity sensor 16 detects the change of the color of the gel in the containing space to obtain the residual amount of the chlorine dioxide gas; when the accommodating space is filled with raw materials for preparing volatile matters, the color change of liquid or gel in the accommodating space is detected by the turbidity sensor 16 so as to obtain the residual amount of the volatile matters.

For convenience of processing, the bottom cover 10 may be directly made of a transparent material so that the turbidity sensor 16 detects a color change in the accommodating space.

For the detection accuracy of the turbidity sensor, the second chamber 101 is disposed away from the first chamber 103, so that when the second reactant is mixed with the first reactant, the turbidity sensor 16 is in a uniform concentration region of the mixed reactant; specifically, because the turbidity sensor 16 is located away from the first chamber 103 storing the first reactant, when the second reactant is mixed with the first reactant, the color inside the first chamber 103 and near the first chamber 103 is darker (the volatile concentration is high), and the color away from the first chamber 103 is lighter (the volatile concentration is low); when the volatile matter volatilizes for a period of time, the concentration of the volatile matter tends to be balanced, namely, the color of the accommodating cavity tends to be consistent. Therefore, in order to ensure the accuracy of the measured concentration of the sterilizing gas, the turbidity sensor 16 is located remotely from the first chamber 103. It should be understood that when the turbidity sensor is included, the first container 11 is not separated from the bottom cover 10, and the detection accuracy of the turbidity sensor is not affected.

In some embodiments, the first chamber 103 is located at the top of the second chamber 101, i.e. the mixing area of the reactants is located above the detection area of the turbidity sensor 16, and at this time, after the reactants are mixed, the sterilizing gas gradually diffuses toward the area where the turbidity sensor is located due to the density of the sterilizing gas being greater than that of the air, so that the turbidity sensor 16 can conveniently detect the sterilizing gas.

In order to prepare as much volatile for sterilization as possible, the volume of the first chamber 103 may be at least one-half or more of the volume of the bottom cap 10, or the volume of the first chamber 103 may be the volume of the bottom cap 10; in some embodiments, in addition to the first cavity 103, another accommodating cavity needs to be provided on the bottom cover 10, and the accommodating cavity needs to be kept a certain distance from the first cavity 103; in particular, in some embodiments, the first chamber 103 has a volume size between 1/3 and 1/2 of the volume size of the bottom cover 10, on the one hand to increase the amount of reactant materials as much as possible, so as to facilitate the preparation of a larger amount of volatile for sterilization; on the other hand, when the bottom cover 10 includes a chamber for accommodating the turbidity sensor 16, it is preferable that the accommodating cavity for accommodating the turbidity sensor 16 is spaced from the first chamber 103, so that the turbidity sensor 16 is located at the central position where the first chamber 103 is mixed with another raw material, that is, the turbidity sensor 16 is located at a position where the concentration of the mixed reactant is uniform as much as possible, thereby ensuring the detection accuracy of the turbidity sensor 16.

When the second reactant is liquid, in order to ensure that the first container 11 can be at least partially separated from the bottom cover 10, the second reactant can easily flow into the first chamber 103, and the liquid level of the second reactant in the top cover 12 at least exceeds the peripheral contour of the first container 11, so that the second reactant can enter the sealed space formed by the first container 11 and the bottom cover 10 after the first container 11 is at least partially separated from the bottom cover 10. In some embodiments, when the refrigerator sterilization module 100 is vertically placed, since the first reactant is located in the enclosed space formed by the first box 11, the first chamber 103 and the sealing part 102, the liquid level of the second reactant at least does not exceed the position of the bottom of the peripheral contour of the first box 11, and preferably does not exceed the position of the top of the peripheral contour of the first box 11, so as to ensure that the second reactant and the first reactant can be easily and sufficiently mixed. In other embodiments, when the refrigerator sterilization module 100 is horizontally suspended on the top of the inner container 200, the level of the second reactant at least does not exceed the position of the overall peripheral contour of the first container 11, and preferably, the level of the second reactant is filled in the overall top cover 12, so as to ensure that the second reactant and the first reactant can be easily mixed.

In order to control the ventilation quantity of the disinfection volatile matter, the disinfection volatile matter ventilation box further comprises a ventilation film 13, and the ventilation film 13 covers the ventilation part of the box body. The air permeable membrane 13 is made of air permeable and water impermeable material, such as PE membrane, PUW membrane, silica gel, or nonwoven fabric.

The gas permeable membrane 13 is a gas permeable and water impermeable material to prevent the outflow of the reactant and/or the reactant product, and in this embodiment, the processing is convenient and gas permeable and water impermeable can be ensured. Because the breathable film is soft and easy to damage, in some embodiments, the breathable film can further comprise a second box body 14, the breathable film 13 is pressed on the top cover 12 by the second box body 14, and at the moment, the second box body 14, the top cover 12 and the bottom cover 10 form a consistent overall outline, so that the integrity and the attractiveness of the refrigerator sterilization module can be ensured; in addition, the second container 14 presses the air permeable membrane 13 on the top cover 12, which can prevent the air permeable membrane 13 from decreasing in sealing property after long-term use and forming a gap with the top cover 12. The second box 14 further comprises a plurality of air holes to facilitate air entering the refrigerator body.

Specifically, the gas permeable membrane 13 is made of a gas permeable and water impermeable material, which may be a gas permeable membrane (such as a PE membrane, a PUW membrane, etc.), a silica gel, a non-woven fabric, etc., on one hand, which is capable of facilitating the gas of the volatile matter to pass through, and on the other hand, which is capable of blocking the liquid from overflowing the household appliance sterilization module 100, and in addition, the gas permeable membrane 13 may prevent the dust outside the sterilization module 100 from entering the household appliance sterilization module. Because different breathable films 13 have different breathable rates, the breathable films 13 can be selected according to the volume of the household appliance, so as to adjust the breathable amount of the volatile matters in the same time period.

The movement of the push rod 15 relative to the case of the refrigerator sterilization module 100 means that the isolation structure is disposed inside the refrigerator sterilization module to form at least two independent chambers therein, and in order to break the isolation structure, the push rod 15 needs to abut against the isolation structure, and at this time, the push rod 15 needs to move relative to the peripheral case of the refrigerator sterilization module or move relative to the isolation structure. When the refrigerator sterilization module 100 is a case, the rod 15 needs to move relative to the case to abut against the isolation structure after activating the refrigerator sterilization module. In some embodiments, the isolation structure may be a membrane structure, and rupturing the membrane structure punctures the membrane; in other embodiments, the isolation structure may be a layer of baffle, and the baffle moves relative to the accommodating space in the box body under the action of an external force, so that the reactants in the independent chambers are mixed with each other, and at this time, the external mechanism acting on the baffle is also a breaking structure.
