Example one

As shown in fig. 1 to 5, a residue detecting structure for a home appliance sterilization module includes a residue indicating body 100, the home appliance sterilization module is a device capable of releasing a sterilizing material in a home appliance, such as a refrigerator, a freezer, or the like, for storing articles and requiring a good storage environment to be maintained; the allowance indication body 100 is installed on the inner container 200 of the household appliance cabinet, and specifically, the allowance indication body 100 may be installed at any position of the inner container 200, such as being placed on the top of the inner container 200, or being disposed in the lateral direction of the inner container 200. The remaining amount indicating body 100 includes: a turbidity sensor 16 electrically connected to the patch terminal on the home appliance cabinet inner container 200 for detecting color change in the home appliance sterilization module; the box body comprises a containing space for containing the sterilizing material or the sterilizing material reaction raw material; an installation cavity of the turbidity sensor 16 is arranged in the box body, and at least part of the installation cavity is made of transparent materials; so that the turbidity sensor 16 detects the color change in the case through the transparent portion of the installation cavity to sense the residual change of the sterilizing material in the home appliance sterilizing module. In order not to affect the accommodating space in the box body, the mounting cavity can extend from the surface of the box body to a position far away from the interior of the box body, and at the moment, the turbidity sensor 16 is bonded or fixed on the mounting cavity through other fixing structures; in other embodiments, the mounting cavity is recessed from the surface of the cassette into the interior of the cassette so that the turbidity sensor 16 is surrounded by the sterilising substance; at this time, the installation cavity is located in the accommodating space of the box body, and although the installation cavity 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, because the installation cavity is formed by sinking towards the inside of the box body, the turbidity sensor 16 can be directly placed in the installation cavity for fixing without other fixing structures.

The box body can be for direct integrated into one piece or assembly forming, and when the box body was assembly forming's box body, the box body included: a bottom cover 10, one side of the bottom cover 10 comprises a first chamber 101 for accommodating the turbidity sensor 16, the first chamber 101 can be shaped and sized according to the turbidity sensor 16, so that the turbidity sensor 16 is stably accommodated on the bottom cover 10, and at least the first chamber 101 is made of a transparent material; and a top cover 12 fixedly connected to the bottom cover 10 and forming a space for accommodating the sterilizing material or the reaction material of the sterilizing material together with the bottom cover 10. It should be noted that the accommodating space is directly used for accommodating the volatile disinfection substances or before the volatile disinfection substances are not used, the accommodating space is used for storing raw materials for preparing the volatile disinfection substances, and the accommodating space is used for storing the volatile disinfection substances during use. In some embodiments, the bottom cover 10 may be ultrasonically welded to the top cover 12; in other embodiments, the bottom cover 10 and the top cover 12 may be fixed by clamping, sleeving, screwing, bonding, or the like, that is, the top cover 12 and the bottom cover 10 are fixedly connected by a detachable connection or a non-detachable connection, and when the non-detachable connection is adopted, the sealing performance of the residue indicating body 100 can be ensured. Specifically, the turbidity sensor 16 indicates the residual amount of sterilizing gas by detecting a color change in the accommodating space when sterilizing volatile is present in the enclosed 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. The sterilizing gas is preferably a green, environmentally friendly, non-toxic sterilizing gas such as: chlorine dioxide, ozone; when the sterilizing gas begins to diffuse into the household appliance box body, the color becomes lighter to indicate that the residual amount of the sterilizing gas is continuously changed, and when the turbidity sensor 16 obtains that the color is not changed, the sterilizing gas is exhausted. Because turbidity sensor 16 needs the change of accurate perception colour, consequently, the comparatively obvious gaseous disinfectant of preferred colour, like the gaseous of yellow chlorine dioxide itself, it has comparatively obvious colour change in constantly diffusing to household electrical appliances box in-process accommodation space, is convenient for turbidity sensor 16 to obtain comparatively accurate data to the surplus condition of reaction disinfectant gas.

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

Before the household appliance sterilization module is not used, the reactant is colorless transparent liquid, after the household appliance sterilization module is activated, liquid or gel with color is formed in the household appliance sterilization module after the reactant is mixed, and the color becomes lighter gradually along with the continuous volatilization of volatile matters for sterilization. At this moment, through utilizing turbidity sensor to detect the change of liquid or gel colour, give the main control board with data transmission to in time know the use surplus of the interior volatile matter of household electrical appliances sterilization module of household electrical appliances box, be convenient for in time change, maintain the interior good storage environment of household electrical appliances box.

The volatile matter for disinfection in the closed space is a finished product or a volatile matter for disinfection prepared on site in real time, and the volatile matter can be gas or gas loaded in liquid or gel. Specifically, the closed space can be used for directly storing the sterilizing gas, but the amount of the sterilizing gas which can be stored is limited due to the limited closed space, and if the household appliance sterilizing module is used, the household appliance sterilizing module needs to be frequently replaced in a short time; in this case, the sterilizing gas may be chlorine dioxide or ozone. In order to obtain the household appliance sterilization module with longer service life and improve user experience, the closed space can be used for storing raw materials for preparing the sterilizing gas, and when the household appliance sterilization module needs to be used, the raw materials for preparing the sterilizing gas are triggered to react so as to prepare a large amount of sterilizing gas.

When the sterilization gas is the finished sterilization gas, the top cover 12 and/or the bottom cover 10 further include a gas permeable area, and a sealing layer (not shown) covering the gas permeable area when the electric home appliance sterilization module is not activated. That is, if the sterilizing gas is the finished product, the remaining indicator body 100 is not permeable before use, but needs a permeable area to allow the sterilizing gas to pass through the home appliance cabinet after use. Therefore, a plurality of vent holes can be formed in the top cover 12 or the bottom cover 10, and a sealing layer can be covered on the plurality of vent holes, the sealing layer can be uncovered and punctured before use, or the sealing layer is a cover body covered on the breathable part, and the sealing layer can be detached when needed. The vent hole may also be a breathable material, such as a breathable membrane. In some embodiments, a gas permeable region and a sealing layer may be disposed on both the top cover 12 and the bottom cover 10, and the sealing layer may be broken to improve the communication between the sterilizing gas and the gas in the household appliance cabinet.

If the sterilizing gas is prepared on site in real time, the balance indicating body 100 includes an independent space at least for storing the reaction raw material of the sterilizing gas. In some embodiments, if chlorine dioxide gas is produced on-site, the balance indicating body 100 includes two or more separate spaces for holding raw materials or other materials. For example, when two separate spaces are included, one space is used to store a first reactant and the other space is used to store a second reactant; for example, one space contains an acidic liquid, such as hypochlorous acid and/or hydrochloric acid, etc., and the second space contains a solid powder, typically chlorate or chlorite powder; it will be appreciated that the acidic liquid may be disposed in the second space and the solid powder may be disposed in the first space. It should be understood that the substance stored in the first space and the second space can be any substance that can combine to generate chlorine dioxide, and the state of the substance is not limited, i.e. the substance can be liquid or solid. For example, chlorine dioxide gas can be generated by reacting an acid solution with an aqueous sodium chlorite solution. In some embodiments, the balance indicating body 100 includes three independent spaces for storing the reaction raw materials of the sterilizing gas, for example, a space for storing water may be added in addition to the space for storing the solid powder and the acidic liquid, and the stored water may be used for dissolving the solid powder to facilitate the whole chemical reaction. Except for storing raw materials for preparing chlorine dioxide gas, a space for storing a flavoring agent can be additionally arranged in the allowance indication body 100, and when the allowance indication body is damaged, the flavoring agent can enter the household appliance box body to flavor the household appliance box body.

It is to be noted that when the preparation of the sterilizing gas is selected, the prepared sterilizing gas is preferably chlorine dioxide; because ozone causes precipitation during chemical preparation, the precipitation affects the detection accuracy of the turbidity sensor 16. Thus, reference in this embodiment to the preparation of a sterilizing gas is to be taken as the reference to chlorine dioxide gas.

In some embodiments, in order to form two independent spaces in the residue indicating body 100, the residue indicating body 100 further includes a first box 11, the first box 11 divides the accommodating space into two independent chambers, each for accommodating a reactant; after the first container 11 is subjected to external force, the first container 11 is partially separated from the bottom cover 10 to mix the two reactants to generate volatile for sterilization. For example, the first container 11 is assembled between the top cover 12 and the bottom cover 10, and after the first container is stressed, a part of the first container 11 still remains connected to the first container 11 or the bottom cover 10, for example, the first container 11 is a flip structure disposed in an accommodating space formed by the top cover 12 and the bottom cover 10, and after the first container 11 is stressed, the part of the first container 11 is separated from the accommodating space, so as to facilitate the mixing of reactants; the first box body has general sealing performance.

In order to further improve the sealing performance of the cartridge body including at least two independent chambers before being activated, in some embodiments, the other side of the bottom cover 10 (the side where the first chamber 101 is located is the side of the bottom cover 10) further includes a second chamber 103, which forms a containing space for the first reactant with the first cartridge body 11; the first box 11 and the top cover 12 form a space for accommodating the second reactant. Specifically, the first container 11 is fitted between the bottom cover 10 and the top cover 12 to form two independent spaces between the bottom cover 10 and the top cover 12. In some embodiments, the first container 11 and the bottom cover 10 are fixedly connected to form a sealed accommodating space, and since the bottom cover 10 and the top cover 12 are fixedly connected, a sealed accommodating space is also formed between the first container 11 and the top cover 12; the fixed connection between the first box 11 and the bottom cover 10 includes, but is not limited to, clamping, sleeving, screwing, etc. Specifically, the first cartridge 11 encloses the first reactant in the second chamber 103 of the bottom cover 10; the first box 11 and the top cover 12 form a storage space for accommodating a second reactant, and at this time, the first reactant and the second reactant are respectively in two mutually isolated spaces. The second cavity 103 extends from the bottom cover 10 to the top cover 12, and the size and the contour of the second cavity 103 are consistent with those of the first container 11, so that a sealed space can be formed between the first container 11 and the second cavity 103. Preferably, the second chamber 103 is disposed far away from the first chamber 101, so that the turbidity sensor 16 is located in a region where the concentration of the first reactant and the second reactant is uniform as much as possible, which facilitates obtaining a more accurate detection result. The first reactant, the second reactant, may be any material capable of generating volatiles for disinfection, and 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 order to facilitate mixing of the first reactant with the second reactant after the home sterilization module is activated, the solid or solid powder fills the second chamber 103 as much as possible or the liquid level of the second reactant reaches the location of the chamber where the first reactant is located), and the fixed powder is typically chlorate or chlorite powder, to mix to generate chlorine dioxide gas; in other embodiments, the first reactant may be provided as an acidic liquid and the second reactant as a solid powder, which facilitates the flow of the liquid reactant from the second chamber 103 to mix with the second reactant. In other embodiments, the first reactant and the second reactant may both be liquids, and only the reaction of the two reactants to generate the sterilizing gas is required. It should be noted that the substance formed by the reaction of the first reactant and the second reactant preferably does not contain a precipitate, so as to prevent the detection accuracy of the turbidity sensor 16 from being affected when the turbidity sensor 16 is included. It should be understood that the first reactant and the second reactant can be any substance that can combine to generate chlorine dioxide, and the state of the substance is not limited, such as: powder, liquid. In other embodiments, the first reactant is a peracid solution and the second reactant is an aqueous sodium chlorite solution, and chlorine dioxide gas is generated by reacting the two liquid solutions. It should be noted that when the first reactant is placed in the second chamber 103 as a liquid, the liquid fills the second chamber 103 to facilitate the mixing of the first reactant and the second reactant.

In some embodiments, the second chamber 103 is located at the top of the first 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.

The second 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 second chamber 103 may be at least one-half or more of the volume of the bottom cap 10, or the volume of the second chamber 103 may be the volume of the bottom cap 10; in some embodiments, in addition to the second 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 second cavity 103; specifically, in some embodiments, the volume of the second chamber 103 is between 1/3-1/2 of the volume of the bottom cover 10, on one hand, to increase the amount of reactant materials as much as possible, so as to facilitate the preparation of larger amounts 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 second chamber 103, so that the turbidity sensor 16 is located at the central position where the second 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 household appliance sterilization module is used, if the raw material for preparing chlorine dioxide gas is stored in the residual indicator body 100, the first container 11 needs to be lifted up by an external force, so that the first reactant and the second reactant can be mixed. In some embodiments, the second chamber 103 further includes a receiving portion 102 for receiving an abutting structure, and the abutting structure abuts against the first case 11 after moving a distance in the receiving portion 102 to lift the first case 11. It should be noted that the first container 11 is still connected to the bottom cover 10 after being lifted up, so as to prevent the measurement accuracy of the turbidity sensor from being affected after falling. The accommodating portion 102 is used for accommodating an abutting structure, which is a top rod 15 in some embodiments, the accommodating portion 102 is sized to accommodate the top rod 15, an end of the top rod 15 accommodated in the accommodating portion 102 is spaced apart from the first box 11 in an initial state, and after the top rod 15 moves toward the first box 11, a tip of the top rod 15 abuts against the first box 11 to enable the first box 11 to generate a gap with respect to the bottom cover 10. In some embodiments, as shown in fig. 2-4, the accommodating portion 102 is a third chamber disposed inside the second chamber 103, that is, the second chamber 103 further includes the third chamber therein, and an accommodating space for the first reactant is formed between the second chamber 103 and the third chamber; the third chamber provides a moving space of the abutting structure to abut against the first case 11 after moving and to make the first case 11 partially separate from the bottom cover 10; the third chamber extends along the extending direction of the first chamber 101 toward the side far away from the inner container of the box, and the third chamber, the abutting structure and the sealing member (e.g., a sealing gasket sleeved on the abutting structure) together form a sealing space to prevent the reactant from flowing out of the third chamber. The shape and size of the accommodating portion 102 are similar to those of the top bar 15, and a gap is formed between the end of the top bar 15 and the first container 11 in the initial state, the gap is generally set between 2mm and 8mm, so that the top bar 15 can abut against the first container 11 after being subjected to an external force by a small distance, and a gap is formed between the first container 11 and the bottom cover 10. In other embodiments, the accommodating portion 102 is disposed at the peripheral edge (not shown) of the second chamber 103, the shape and size of the accommodating portion 102 are similar to those of the rod 15, and the accommodating portion 102 extends toward the extending direction of the second 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 first container 11 includes a protrusion 111 protruding from the first container 11, and the protrusion 111 is retained on the bottom cover 10 after the home sterilization module is activated. Specifically, the first box 11 includes a protrusion 111, the protrusion 111 extends away from the household appliance inner container 200 or extends close to the household appliance inner container 200, and the protrusion 111 is hung on or sleeved on the bottom cover 10 or the accommodating portion 102 of the bottom cover 10 before and after activation of the household appliance sterilization module. When the third chamber is included on the bottom cover 10, the opening size of the protrusion 111 is larger than the opening size of the third chamber and the protrusion 111 may be in any shape or the opening size of the protrusion 111 is smaller than the opening size of the third chamber and the protrusion 111 may be in any shape. In some embodiments, the protrusion 111 extends away from the appliance liner 200, wherein the opening of the protrusion 111 is larger than the opening of the third compartment, and the protrusion 111 initially hangs from the third compartment. In other embodiments, the protrusion 111 extends toward the side close to the liner 200 of the household appliance, at this time, the opening of the protrusion 111 is smaller than the opening of the third chamber, and the protrusion 111 is initially sleeved on the third chamber. When the first container 11 is forced, the first container 11 is lifted, but because of the protrusion 111, the first container 11 can still be held on the third chamber of the bottom cover 10 by the protrusion 111 and will not fall.

In some embodiments, in order to make the first container 11 form a gap with the bottom cover 10 after being stressed, the first container 11 can be a flip structure disposed on the bottom cover 10, and the flip structure is initially sealed with the bottom cover 10, and the top rod 15 pushes up the flip structure to mix the second reactant with the first reactant.

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 second chamber 103, and the liquid level of the second reactant in the top cover 12 at least exceeds the peripheral profile 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 electric home sterilization module is vertically disposed, since the first reactant is located in the closed space formed by the first box 11, the second chamber 103 and the accommodating portion 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 domestic sterilization module is horizontally suspended on the top of the inner container, the level of the second reactant at least exceeds the position of the overall peripheral contour of the first box 11, and preferably the level of the second reactant fills the overall top cover 12, so as to ensure that the second reactant and the first reactant can be easily mixed.

The top cover 12 is used for forming a sealing structure with the bottom cover 10, at least part of the sealing structure comprises a ventilation part with a plurality of ventilation holes, the ventilation part is sealed and covered with a breathable film 13, and the breathable film 13 is made of breathable and waterproof materials. Before the household appliance sterilization module is not used, a second reactant is arranged in the top cover 12, and the second reactant cannot flow out of the breathable film 13 through the breathable part; after the household appliance sterilization module is used, the first reactant and the second reactant are mixed to generate chlorine dioxide gas, and the chlorine dioxide gas can enter the household appliance box body through the breathable film 13.

In some embodiments, the household appliance sterilization module further comprises a second box body 14, the breathable film 13 is pressed on the top cover 12 by the second box body 14, and at this time, the second box body 14, the top cover 12 and the bottom cover 10 form a consistent overall contour, so that the integrity and the aesthetic property of the household appliance 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 household appliance box.

The breathable film 13 is made of breathable and waterproof material, and can be breathable film (such as PE film, PUW film, etc.), silica gel, non-woven fabric, etc., on one hand, the gas of volatile matter can pass through conveniently, on the other hand, the liquid can be blocked to overflow the household appliance sterilization module, and in addition, the breathable film 13 can prevent the dust outside the sterilization module 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.
