[0059] Embodiment 1

[0060] The present invention provides a household appliance sterilization module, as Figure 1 shown, which includes a sterilization module body 1 disposed on the inner wall of the inner container 2 of the household appliance. The sterilization module body 1 includes a sterilization box 100 for generating a volatile bactericide; wherein, the sterilization box 100 includes:

[0061] A first chamber 110 for storing a first reactant;

[0062] A second chamber 120 for storing a second reactant;

[0063] A separation layer 130 for separating the first chamber 110 from the second chamber 120; the separation layer 130 is a plastic film layer; further, the plastic film layer is a layer with air permeability and water impermeability, and the strength of the plastic film layer is not high and can be punctured by mechanical force; in one embodiment, the separation layer 130 is a plastic-sealed film layer;

[0064] A plurality of first air vents 140 and a puncture structure body 150;

[0065] The puncturing structure body 150 is used to puncture the separation layer 130, so that the first reactant and the second reactant are mixed and react to generate a volatile bactericide. The volatile bactericide overflows from a plurality of first air vents 140 into the household electrical appliance box body for sterilization. In one embodiment, the puncturing structure body 150 is driven by a driving component to move to the separation layer 130 and puncture the separation layer 130; in another embodiment, the puncturing structure body 150 is rotated to move the puncturing structure body 150 to the separation layer 130 and puncture the separation layer 130.

[0066] In one embodiment, the volatile bactericide is chlorine dioxide gas. Chlorine dioxide is a broad-spectrum, highly efficient and non-toxic bactericidal disinfectant, which has the advantages of low effective concentration and fast action speed, and is widely used as a bactericidal disinfectant and a food preservative. Chlorine dioxide gas can be generated by the reaction of a solid-phase reactant and a liquid-phase reactant, such as a solid-phase chlorite and a liquid-phase acidic reactant, such as a solid-phase sodium chlorite and a liquid-phase hydrochloric acid.

[0067] In one embodiment, as Figure 2 shown, a breathable film 160 is provided on one side of a plurality of first air vents 140 facing the storage area of the household electrical appliance box body. The breathable film 160 is breathable and isolates liquids and solids, so as to prevent the first reactant or the second reactant in the sterilization box 100 from overflowing from the first air vents 140 into the household electrical appliance box body, causing pollution to the household electrical appliance box body and certain usage hazards. Further, the amount of the volatile matter for sterilization overflowing from the sterilization module body into the refrigerator box body is adjusted by adjusting the air permeability of the breathable film 160.

[0068] In one embodiment, as Figure 1 、 Figure 2 、 Figure 9 shown, the sterilization box 100 further includes a cover body 170 for covering the first air vents 140 to improve the aesthetics of the sterilization box 100. In addition, the cover body 170 can also play a role in dust prevention.

[0069] In one embodiment, the cover body 170 is suspended and fixed outside the side wall structure provided with the first air vents 140, that is, there is a gap between the cover body 170 and the side wall structure provided with the first air vents 140, so that the volatile bactericide overflowing from the first air vents 140 can smoothly enter the storage area of the household electrical appliance box body for sterilization. In another embodiment, as Figure 9 shown, the cover body 170 is made of a breathable material or the cover body 170 is provided with second air vents 171, so that the volatile bactericide overflowing from the first air vents 140 can smoothly enter the storage area of the household electrical appliance box body for sterilization.

[0070] In one embodiment, the cover 170 is snap-connected to the side wall structure provided with the first ventilation opening 140, so that the cover 170 can be detached from the side wall structure provided with the first ventilation opening 140. For example, when the sterilization function of the sterilization box 100 is turned on and the generated volatile fungicide is exhausted, instead of replacing the entire sterilization box 100, the cover 170 can be removed without replacing the cover 170, and only the component of the sterilization box 100 for generating the volatile fungicide needs to be replaced, thus saving costs. In addition, if the first reactant or the second reactant in the sterilization box 100 overflows from the first ventilation opening 140 and adheres to the ventilation membrane 160, and accumulates over a long time, resulting in a decrease in the ventilation of the ventilation membrane 160, the cover 170 can be removed to replace the ventilation membrane 160.

[0071] In one embodiment, as Figure 1 、 Figure 9 、 Figure 11 、 Figure 12 shown, the sterilization module body 1 further includes a mounting seat 200 for fixing the sterilization box 100; the mounting seat 200 is fixed to the inner container 2.

[0072] Further, the mounting seat 200 includes:

[0073] A base 210, embedded in the side of the inner container 2 of the household electrical appliance box body facing away from the storage area of the household electrical appliance box body;

[0074] A fixing seat 220, fixed to the side of the base 210 facing the storage area of the household electrical appliance box body;

[0075] The sterilization box 100 is fixed to the side of the fixing seat 220 facing the storage area of the household electrical appliance box body. In one embodiment, as Figure 1 、 Figure 5 shown, the inner container 2 is provided with a second through groove 201, and the base 210 covers the side of the second through groove 201 of the inner container 2 facing away from the storage area of the household electrical appliance box body to close the second through groove 201, so as to prevent the foaming material from overflowing into the interior of the household electrical appliance box body through the second through groove 201 during the foaming of the household electrical appliance box body and affecting the appearance; after the fixing seat 220 is fixed to one side of the base 210, it covers the side of the second through groove 201 of the inner container 2 facing the storage area of the household electrical appliance box body.

[0076] In one embodiment, as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5As shown, the sterilization module body 1 further includes a remaining amount detection device 400 for detecting the remaining amount of the volatile bactericide in the sterilization cartridge 100; the sterilization cartridge 100 is provided with a transparent area for the remaining amount detection device 400 to detect the remaining amount of the volatile bactericide in the sterilization cartridge 100. In an embodiment, the sterilization cartridge 100 contains a gel body with bactericidal volatile substances, and the bactericidal volatile substances are located in the pores of the gel body; the gel body releases the volatile bactericide, and as time goes by, the amount of the volatile bactericide in the gel body decreases, and then the amount of the volatile bactericide released by the gel body into the sterilization cartridge 100 also decreases until the volatile bactericide in the gel body is completely released or nearly completely released, and the remaining amount of the volatile bactericide in the sterilization cartridge 100 can be determined; further, according to the speed at which the gaseous volatile bactericide in the sterilization cartridge 100 overflows into the storage area of the household appliance cabinet, the time for reminding the user to update can be judged. Further, the sterilization cartridge 100 contains a chlorine dioxide gel body with chlorine dioxide volatiles, and chlorine dioxide is located in the pores of the chlorine dioxide gel body. The chlorine dioxide gel body releases chlorine dioxide volatiles into the sterilization cartridge 100, and the chlorine dioxide volatiles then overflow into the storage area of the household appliance cabinet for sterilization. Chlorine dioxide is a broad-spectrum, highly efficient and non-toxic bactericidal disinfectant, which has the advantages of low effective concentration and fast action speed, and is widely used as a bactericidal disinfectant and a food preservative. In an embodiment, the remaining amount detection device 400 detects the color change of the chlorine dioxide gel body in the sterilization cartridge 100 through the transparent area of the sterilization cartridge 100 to judge the remaining amount of chlorine dioxide contained in the chlorine dioxide gel body, and then the remaining amount of the chlorine dioxide volatiles released by the chlorine dioxide gel body into the sterilization cartridge 100 can be judged. In an embodiment, the sterilization cartridge 100 is a chlorine dioxide generator. The sterilization cartridge 100 is installed on one side of the base facing the storage area of the household appliance cabinet. When sterilization needs to be started, the partition layer 130 between the first chamber 110 and the second chamber 120 of the sterilization cartridge 100 is destroyed by mechanical force, and the first reactant in the first chamber 110 contacts and reacts with the second reactant in the second chamber 120 to generate a chlorine dioxide gel body ranging from yellowish-green to orange-yellow. The chlorine dioxide gel body has a porous structure, and chlorine dioxide volatiles are stored in the voids. The chlorine dioxide gel body releases chlorine dioxide gas (i.e., chlorine dioxide volatiles), and the chlorine dioxide gas overflows from the sterilization cartridge 100 into the household appliance cabinet to sterilize the storage area of the household appliance cabinet. As the sterilization time prolongs, the chlorine dioxide in the chlorine dioxide gel body gradually decreases, and the color of the gel body gradually fades from the original yellowish-green to orange-yellow until the gel body becomes colorless or nearly colorless. The remaining amount detection device 400 detects the color change of the chlorine dioxide gel body in the sterilization cartridge 100 caused by the gradual consumption of chlorine dioxide contained therein, and then the remaining amount of chlorine dioxide in the chlorine dioxide gel body can be judged.It should be understood that the first reactant or the second reactant in the sterilization cartridge 100 further includes a gelling agent so that a chlorine dioxide gel can be formed by the reaction; further, the first reactant or the second reactant in the sterilization cartridge 100 further includes an auxiliary material for promoting the release of chlorine dioxide gas from the chlorine dioxide gel formed by the reaction. It should be understood that after the partition layer 130 of the sterilization cartridge 100 is damaged by mechanical force, it hangs at the connection between the partition layer 130 and the inner wall of the sterilization cartridge 100, or the partition layer 130 is a colorless and transparent plastic-sealed film layer, and falling anywhere in the sterilization cartridge 100 will not affect the detection information of the remaining amount detection device 400 on the color change of the chlorine dioxide gel in the sterilization cartridge 100. It should be understood that the first reactant and the second reactant are mixed and reacted in a chamber containing a liquid reactant, and the liquid reactant is a colorless and transparent liquid. The remaining amount detection device 400 detects the color change information of the chlorine dioxide gel formed by the reaction in the chamber containing the liquid reactant from the transparent area of the sterilization cartridge 100, so as to avoid the solid reactant or the colored liquid reactant from affecting the detection result accuracy of the remaining amount detection device 400. Further, the household appliance further includes an alarm module. In one embodiment, when the remaining amount detection device 400 detects from the transparent area of the sterilization cartridge 100 that the color of the chlorine dioxide gel in the sterilization cartridge 100 is colorless, that is, when the remaining amount detection device 400 detects that all the chlorine dioxide in the chlorine dioxide gel in the sterilization cartridge 100 has been released, the information is sent to a control board electrically connected to the remaining amount detection device 400, and the control board sends an alarm instruction to the alarm module, and the alarm module issues an alarm to remind the user to replace the sterilization cartridge 100 in time. The alarm methods include but are not limited to flashing, sounding, and color gradient. In another embodiment, when the remaining amount detection device 400 detects that the remaining amount of chlorine dioxide in the chlorine dioxide gel in the sterilization cartridge 100 is nearly exhausted, the alarm module gives an alarm. A threshold value for the remaining amount of chlorine dioxide in the chlorine dioxide gel detected by the remaining amount detection device 400 to meet the alarm condition of the alarm module is preset. When the remaining amount of chlorine dioxide in the detected chlorine dioxide gel reaches the threshold value, the control board sends an alarm instruction to the alarm module. It should be understood that the volatile bactericide is a gel containing other bactericide volatiles with colors, and all of them can be applied to the present invention, which will not be elaborated here. Further, the remaining amount detection device 400 is a turbidity sensor, which detects the color change of the chlorine dioxide gel in the sterilization cartridge 100 through the transparent area of the sterilization cartridge 100 to judge the remaining amount of chlorine dioxide contained in the chlorine dioxide gel, and further can judge the remaining amount of the chlorine dioxide volatiles released from the chlorine dioxide gel into the sterilization cartridge 100.

[0077] In one embodiment, the sterilization module body 1 further includes a terminal 300 for electrically connecting the remaining amount detection device 400; a base 210 of the mounting base 200 provided on the sterilization module body 1 is provided with a first through groove 211 for clamping the terminal 300; the remaining amount detection device 400 provided on the sterilization module body 1 is inserted into the terminal 300 from the side of the base 210 facing the storage area of the household appliance box body. The first end 310 of the terminal 300 passes through the first through groove 211 from the side of the base 210 facing away from the storage area of the household appliance box body, and the first end 310 of the terminal 300 extends into the side of the base 210 facing the storage area of the household appliance box body. The second end 320 of the terminal 300 is located on the side of the base 210 facing away from the storage area of the household appliance box body, so that the remaining amount detection device 400 is inserted into the interface of the first end 310 from the side of the base 210 facing the storage area of the household appliance box body, and then the remaining amount detection device 400 is installed on the base 210 and connected to the terminal 300. Further, the inner contour of the first through groove 211 abuts against the circumferential contour of the first end 310 of the terminal 300, so that the first end 310 of the terminal 300 is clamped in the first through groove 211, and then the terminal 300 is installed on the base 210.

[0078] Further, as Figure 1 shown, the outer contour of the side of the first through groove 211 facing away from the storage area of the household appliance box body abuts against the side of the second end 320 of the terminal 300 facing the storage area of the household appliance box body, so that the second end 320 seals the first through groove 211 on one side, and when the household appliance box body is foamed, the foaming material will not overflow from the first through groove 211.

[0079] In one embodiment, as Figure 5 shown, the side of the base 210 facing the storage area of the household appliance box body is provided with a buckle structure 212 for fixing the remaining amount detection device 400. The buckle structure 212 is buckled with a first clamping protrusion 410 provided on the remaining amount detection device 400 to limit the movement of the remaining amount detection device 400 in the direction away from the terminal 300, and the remaining amount detection device 400 is fixed to a certain extent. Further, after the remaining amount detection device 400 is inserted into the interface of the first end 310 of the terminal 300 and the buckle structure 212 buckles the first clamping protrusion 410 of the remaining amount detection device 400, the side wall of the first through groove 211 provided on the base 210 abuts against one side of the remaining amount detection device 400 to limit the movement of the remaining amount detection device 400 in the direction towards the terminal 300, so as to firmly fix the remaining amount detection device 400. Through a second through groove 201 provided in the inner container 2, the remaining amount detection device 400 is opposite to the transparent area of the sterilization box 100. The sterilization box 100 is located on the side of the base 210 facing the storage area of the household appliance box body, and the remaining amount detection device 400 detects the remaining amount of chlorine dioxide gas in the sterilization box 100 through the transparent area of the sterilization box 100.

[0080] Further, as Figure 1 shown, the fixing base 220 and the base 210 form a cavity for accommodating the remaining amount detection device 400. The setting of the fixing base 220 covers the remaining amount detection device 400 to prevent the remaining amount detection device 400 from being exposed in the storage area of the household appliance box body, which affects the overall aesthetics inside the household appliance box body. Further, the sterilization box 100 is arranged on one side of the fixing base 220 facing the storage area of the household appliance box body. In order to make the remaining amount detection device 400 and the transparent area of the sterilization box 100 opposite to each other, the fixing base 220 is provided with a third through groove 221 for making the remaining amount detection device 400 face the transparent area of the sterilization box 100, so that the remaining amount detection device 400 can detect the remaining amount of the volatile sterilizing agent in the sterilization box 100.

[0081] In one embodiment, as Figure 1 、 Figure 12 shown, the fixing base 220 covers the outer contour of one side of the base 210 facing the second through groove 201 to cover the base 210 embedded in the inner liner 2, and modifies the inner wall of the inner liner 2 to improve the cleanliness of the inner wall of the inner liner 2.

[0082] In one embodiment, as Figure 1 shown, the fixing base 220 and the base 210 are fixed by screws 230. Further, the base 210 is recessed inward in the direction away from the storage area of the household appliance box body to form a first recess 213, and the fixing base 220 is recessed inward in the direction away from the storage area of the household appliance box body to form a second recess 222. The back surface of the second recess 222 extends into the first recess 213 after passing through the second through groove 201 of the inner liner 2. The inner wall of the first recess 213 and the inner wall of the second recess 222 are fixed by screws 230, and the screws seal the assembly holes of the first recess 213 and the second recess 222 to prevent the foaming material from overflowing from the assembly holes. Further, one end of the sterilization box 100 extends into the second recess 222 of the fixing base 220, and the sterilization box 100 is accommodated in the second recess 222, so that the installation of the sterilization box 100 in the inner liner 2 is not obtrusive, and the structure is small and compact.

[0083] Further, as Figure 1 、 Figure 3 shown, the base 210 is provided with a first abutting portion 214 for abutting against the outer wall of the inner liner 2 on the side away from the storage area of the household appliance box body. Further, the first abutting portion 214 is bonded to the outer wall of one side of the inner liner 2 to fix the base 210 on the inner liner 2. The outer contour of the first abutting portion 214 facing the inner liner 2 tightly abuts against the inner liner 2 to increase the bonding area between the first abutting portion 214 and the inner liner 2 and improve the fixing firmness of the base 210.

[0084] Further, as Figure 1 、 Figure 3As shown, there is a gap between the side wall of the fixing base 220 away from the base 210 and the inner container 2. The side wall of the fixing base 220 away from the base 210 is bent in the direction towards the base 210 to form a second abutting portion 223 for abutting against the outer wall of the inner container 2 facing the storage area of the household electrical appliance box body. The fixing base 220 seals the second through groove 201 of the inner container 2 through the second abutting portion 223, so as to improve the overall aesthetic degree of the surface of the inner container 2.

[0085] In one embodiment, as Figure 12 shown, the sterilization module body 1 is arranged on the inner wall of the top of the inner container 2. In one embodiment, the sterilization module body 1 is bonded to the outer wall of one side of the inner container 2 through the first abutting portion 214 of the base 210 of the mounting base 200 and then mounted on the door liner 2. The base 210 and the inner container 2 are tightly connected through the bonding effect. The sterilization module body 1 is arranged on the top of the inner container 2, and the gravity of the sterilization module body 1 will not cause the base 210 to separate from the inner container 2, ensuring the stable connection between the sterilization module body 1 and the inner container 2.

[0086] In one embodiment, as Figure 1 、 Figure 2 shown, the puncturing structure body 150, the first chamber 110, the partition layer 130, and the second chamber 120 are arranged in sequence along the direction away from the inner wall of the inner container 2.

[0087] In one embodiment, the puncturing structure body 150 is arranged at one end of the sterilization box 100; a connecting structure for rotationally engaging with the inner wall of the inner container 2 is provided on an outer surface of the puncturing structure body 150 facing the household electrical appliance inner container 2; wherein,

[0088] When installing the sterilization box 100, rotate the puncturing structure body 150 to drive the connecting structure to rotate and engage with the inner wall of the inner container 2, thereby completing the installation of the sterilization box 100;

[0089] When activating the sterilization box 100, an external force drives the puncturing structure body 150 to approach the partition layer 130, so that the puncturing end punctures the partition layer 130.

[0090] In one embodiment, the puncturing structure body 150 is disposed in the first chamber 110 of the sterilization cartridge 100; an external force drives the puncturing structure body 150 to approach the separation layer 130 so as to puncture the separation layer 130, enabling the first reactant in the first chamber 110 to be mixed with the second reactant in the second chamber 120 and react to generate a volatile bactericide, and the volatile bactericide overflows from the first air vent 140 of the sterilization cartridge 100 to the household appliance housing to sterilize the household appliance housing. Further, a sealing ring 180 is provided between the puncturing structure body 150 and the inner wall of the first chamber 110 of the sterilization cartridge 100 to prevent the reactant in the first chamber 110 from leaking between the puncturing structure body 150 and the inner wall of the first chamber 110 of the sterilization cartridge 100. The puncturing structure body 150 can be pushed to approach the separation layer 130 of the sterilization cartridge 100 manually or by mechanical force.

[0091] In one embodiment, as Figure 1 shown, the outer circumferential outer wall of the puncturing structure body 150 is provided with an external thread for threaded connection with the inner wall of the first chamber 110 having an external thread, that is, the puncturing structure body 150 can be screwed in and out in the first chamber 110; when the first chamber 110 of the sterilization cartridge 100 is rotated, the puncturing structure body 150 rotates therewith, so that the connection structure provided on the puncturing structure body 150 is buckled on the inner wall of the inner container 2 with the rotation to complete the installation of the sterilization cartridge 100; in one embodiment, when the sterilization cartridge 100 is rotated, the first chamber 110 rotates therewith; wherein,

[0092] After the rotating sterilization box 100 fastens the puncturing structure body 150 to the inner wall of the inner container 2, continue to rotate the sterilization box 100 in the same direction so that the puncturing structure body 150 screws into the first chamber 110 to approach the partition layer 130 and puncture the partition layer 130, enabling the first reactant and the second reactant to mix and react to generate a volatile bactericide. The volatile bactericide overflows from the first air vent 140 of the sterilization box 100 to the household appliance cabinet to sterilize the household appliance cabinet. The rotation direction of fastening the puncturing structure body 150 to the inner wall of the inner container 2 in the first chamber 110 is the same as the rotation direction of the first chamber 110 when the puncturing structure body 150 screws into the first chamber 110, so as to avoid the rotation direction of the first chamber 110 when the puncturing structure body 150 screws into the first chamber 110 being opposite to the rotation direction of the first chamber 110 when the puncturing structure body 150 is fastened to the inner wall of the inner container 2, which may cause the puncturing structure body 150 to rotate when starting to puncture, resulting in the puncturing structure body 150 detaching from the fastening on the inner wall of the inner container 2 and causing the sterilization box 100 to fall. When designing the puncturing structure body 150, the rotation angle of the puncturing structure body 150 (i.e., the first chamber 110) when it is fastened to the inner wall of the inner container 2 and the rotation angle of the first chamber 110 when puncturing the partition layer 130 can be specifically defined to facilitate installation and opening of the puncturing. For example, the puncturing structure body 150 rotates 15° to fasten the puncturing structure body 150 to the inner wall of the inner container 2 to complete the installation of the sterilization box 100, and then continue to rotate the first chamber 110 in the same direction to 180° so that the puncturing structure body 150 punctures the partition layer 130. Since the puncturing structure body 150 is fixed to the inner wall of the inner container 2 and the continued rotation direction of the first chamber 110 is the same as the rotation direction when the puncturing structure body 150 is fastened to the inner wall of the inner container 2, when continuing to rotate the first chamber 110 in the same direction, the puncturing structure body 150 is tightly fastened to the inner wall of the inner container 2, that is, the puncturing structure body 150 does not move relative to the inner wall of the inner container 2, but moves in a screwing motion relative to the first chamber 110, and finally punctures the partition layer 130.

[0093] In one embodiment, the volatile bactericide is chlorine dioxide gas, which is generated by the reaction of a solid-phase reactant and a liquid-phase reactant. The space occupied by the solid-phase reactant is smaller than that occupied by the liquid-phase reactant. The circumferential side of the puncturing structure body 150 is threadedly connected to the inner wall of the first chamber 110. To save costs, the volume of the puncturing structure body 150 should not be large, so the space of the first chamber 110 should not be too large. Furthermore, the first chamber 110 is preferably used to store the first reactant in a solid state, and the second chamber 120 is used to store the second reactant in a liquid state. Further, the second chamber 120 surrounds the outer wall circumferential side of the first chamber 110, increasing the accommodation space of the second chamber 120 to a certain extent. The puncturing structure body 150, the inner wall of the first chamber 110, and the partition layer 130 form a space for accommodating the first reactant. When installing the sterilization cartridge 100, rotate the sterilization cartridge 100 so that the first chamber 110 drives the puncturing structure body 150 to rotate together, and then rotate and snap onto the fixing seat 220; continue to rotate the sterilization cartridge 100 in the same direction. Since the puncturing structure body 150 is fixed by the base 210 and the fixing seat and does not move, the first chamber 110 rotates relative to the puncturing structure body 150, causing the puncturing structure body 150 to screw into the first chamber 110 until the partition layer 130 is punctured. In one embodiment, the sterilization module body 1 is disposed on the inner wall of the top of the inner tank 2. Then, the first chamber 110 is located above the second chamber 120. When the partition layer 130 is punctured, the first reactant in the first chamber 110 drops into the second chamber 120 under gravity, and then mixes with the second reactant in the second chamber 120 to trigger a reaction. Due to the assistance of gravity, the mixing speed of the first reactant and the second reactant is accelerated, and the amount of the first reactant remaining in the first chamber 110 is reduced, improving the generation amount of the volatile bactericide.

[0094] Specifically, as Figure 1 、 Figure 2 shown, the first chamber 110 of the sterilization cartridge 100 is disposed in the end cap 101, and the second chamber 120 is disposed in the cartridge body 102. The end cap 101 is provided with a cylindrical convex portion in the direction towards the cartridge body 102. A hollow portion is provided inside the convex portion. The inner wall of the hollow portion of the end cap 101 is provided with an internal thread for threadedly connecting with the puncturing structure body 150. The puncturing structure body 150 seals the side of the hollow portion of the end cap 101 facing away from the cartridge body 102, and the partition layer 130 seals the side of the hollow portion of the end cap 101 facing the cartridge body 102 to form the first chamber 110. The cartridge body 102 is recessed towards the end cap 101 to form a cavity. The circumferential side wall of the cartridge body 102 abuts against the surface of the end cap 101 facing the cartridge body 102, and then the communication portion between the cartridge body 102 and the end cap 101 is sealed by the partition layer 130 to form the second chamber 120. In one embodiment, the connection manner between the end cap 101 and the cartridge body 102 includes but is not limited to snap connection, screw connection, and ultrasonic welding.

[0095] Further, when the sterilization cartridge 100 is disposed at the top of the inner container 2, after the puncturing structure body 150 punctures the separation layer 130, the solid-phase first reactant in the first chamber 110 of the end cap 101 drops into the second chamber 120 of the cartridge body 102 to react with the liquid-phase second reactant. When the sterilization cartridge 100 is disposed on the side wall of the inner container 2, after the puncturing structure body 150 punctures the separation layer 130, since the first chamber 110 of the end cap 101 extends into the cavity of the cartridge body 102, that is, without the blocking of the side wall structure of the separation layer 130, the first reactant in the first chamber 110 slides into the second chamber 120 of the cartridge body 102 to react with the liquid-phase second reactant.

[0096] Further, the cartridge body 102 is a transparent member. When installing the remaining amount detection device 400, the remaining amount detection device 400 faces the side wall of the cartridge body 102, and detects the remaining amount of the volatile bactericide generated in the second chamber 120 of the cartridge body 102 through the cartridge body 102.

[0097] Further, the first vent 140 is disposed on the bottom wall of the cartridge body 102, and the cover body 170 is snap-connected to the cartridge body 102. Specifically, the cartridge body 102 is provided with at least two second card slots 1021, and the cover body 170 is provided with second engaging protrusions 172 that match the second card slots 1021. The cover body 170 and the cartridge body 102 are detachably connected by snapping the second engaging protrusions 172 into the second card slots 1021. Further, the cartridge body 102 is provided with four second card slots 1021, and the four second card slots 1021 are annularly distributed. The cover body 170 is provided with four second engaging protrusions 172 to improve the snap connection firmness between the cover body 170 and the cartridge body 102.

[0098] The puncturing structure body 150 is cylindrical, and the outer contour of the puncturing structure body 150 is closely attached to the inner contour of the first chamber 110 to prevent the reactants stored in the sterilization cartridge 100 from leaking from the connection between the puncturing structure body 150 and the first chamber 110.

[0099] In one embodiment, as Figure 1 、 Figure 6 shown, the puncturing end includes a plurality of first sharp corners 151 provided on the end face of the puncturing structure body 150 facing the separation layer 130, so that the puncturing structure body 150 can puncture the separation layer 130. Further, the plurality of first sharp corners 151 are arranged in an annular array. As the puncturing structure body 150 rotates, the plurality of first sharp corners 151 apply a puncturing force along the trajectory of the circumference where the first sharp corners 151 are located on the separation layer 130 to expand the torn opening of the separation layer 130, so as to increase the mixing speed of the first reactant in the first chamber 110 and the second reactant in the second chamber 120.

[0100] In one embodiment, as Figure 1As shown, the first sharp corner 151 faces the connection between the separation layer 130 and the inner contour of the first chamber 110 to pierce the separation layer 130 so that the separation layer 130 detaches from the inner contour connection of the first chamber 110, that is, to completely expose the opening of the first chamber 110 facing the second chamber 120, so as to improve the mixing speed of the first reactant in the first chamber 110 and the second reactant in the second chamber 120, and at the same time make the first reactant and the second reactant fully mixed, improving the utilization rate of the reaction raw materials.

[0101] In one embodiment, as Figure 1 、 Figure 6 shown, the piercing structure body 150 has a hollow structure; the piercing end includes a second sharp corner 152 axially provided in the hollow area of the piercing structure body 150. Further, the second sharp corner 152 points to the central position of the separation layer 130 to act simultaneously with the first sharp corner 151 to accelerate the piercing of the separation layer 130.

[0102] In one embodiment, as Figure 1 、 Figure 6 shown, a first card slot 153 for clamping the sealing ring 180 is provided on the circumferential side of the end of the piercing structure body 150 close to the separation layer 130. After the sealing ring 180 is clamped in the first card slot 153, the sealing performance between the piercing structure body 150 and the inner wall of the first chamber 110 is improved, preventing the first reactant and / or the second reactant in the sterilization box 100 from overflowing from the connection between the piercing structure body 150 and the inner wall of the first chamber 110 to the outside of the sterilization box 100, causing waste of raw materials and reducing the use safety.

[0103] In one embodiment, as Figure 7 、 Figure 8 、 Figure 9 shown, the piercing structure body 150 is provided with a second installation part 520, and the fixed seat 220 of the installation seat 200 provided on the sterilization module body 1 is provided with a first installation part 510; the first installation part 510 and the second installation part 520 are buckled through a reverse buckle structure after the convex rib is inserted into the groove and rotated. When the sterilization box 100 needs to be removed from above, reverse rotation can make the piercing structure body 150 detach from the buckle with the inner wall of the inner container 2.

[0104] Further, in one embodiment, the convex rib of the first mounting portion 510 is separately provided from the corresponding first inverted structure, and the groove of the second mounting portion 520 is separately provided from the corresponding second inverted structure. After the convex rib of the first mounting portion 510 extends into the groove of the second mounting portion 520, the convex rib can rotate or rotate a certain distance in the groove until the first inverted structure and the second inverted structure are engaged. Among them, the convex rib and the groove play an auxiliary positioning role to increase the installation speed. Further, the first inverted structure and the second inverted structure are engaged, and the groove of the second mounting portion 520 plays a limiting role on the convex rib of the first mounting portion 510 to prevent continued rotation in the same direction from causing the first inverted structure and the second inverted structure to disengage.

[0105] In another embodiment, the second mounting portion 520 includes two arc-shaped grooves respectively provided with the second inverted structure; the two convex ribs respectively provided with the first inverted structure of the first mounting portion 510 extend into the two grooves of the second mounting portion 520, respectively, and rotate to make the matching first inverted structure and the second inverted structure engage with each other. In one embodiment, the arc lengths of the two grooves of the second mounting portion 520 are different, and the two grooves are located on the same circumference. The large and small structures of the two grooves can play a fool-proof role. For example, the puncture structure body 150 rotates from the large groove to the small groove in the direction of installing the sterilization box 100, and the reverse direction is the rotation direction of disassembling the sterilization box 100. In another embodiment, the two grooves are rotationally symmetrical, and the arc lengths of the two grooves are the same. The two rotationally symmetrical grooves are easy to process. It should be understood that the length of the arc of the groove provided in the second mounting portion 520 is slightly longer than the length of the arc of the convex rib provided in the first mounting portion 510, that is, the convex rib provided with the first undercut structure can be smoothly inserted into the matching groove, and when the first undercut structure is rotated to engage with the second undercut structure, a gap is left between a side wall of the groove away from the undercut engagement connection and an end of the corresponding convex rib away from the undercut engagement connection, and the gap is not large enough to allow the first mounting portion 510 to be easily separated from the second mounting portion 520. After the second undercut structure of the second mounting portion 520 is engaged with the first undercut structure provided in the first mounting portion 510, the gap between a side wall of the groove away from the undercut engagement connection and an end of the corresponding convex rib away from the undercut engagement connection increases, so that the puncture structure body 150 can be smoothly detached from the first mounting portion 510 when the puncture structure body 150 is rotated in the reverse direction. The increased arc distance is the arc length of the first inverted structure and / or the second inverted structure. Furthermore, the arc length of the first inverted structure is the same as that of the second inverted structure.

[0106] Furthermore, the second reverse buckling structure of the second installation part 520 of the puncturing structure body 150 is arranged at one end of the groove, and the positions of the second reverse buckling structures of the two grooves are opposite. The second reverse buckling structure is arranged at one end of the groove facing the rotation direction during buckling. When the second reverse buckling structure is buckled with the first reverse buckling structure on the inner wall of the inner container 2, the sterilization box 100 is hung on the inner wall of the inner container 2, and when there is no external force for reverse rotation, the second reverse buckling structure and the first reverse buckling structure cannot be separated from the buckled state. It should be understood that when the sterilization box 100 is installed, the positions of the two grooves are such that after the first reverse buckling structure and the second reverse buckling structure are buckled, they will not be separated from the buckled state due to the self-gravity of the sterilization box 100. Preferably, the sterilization box 100 is installed at the top of the inner container, the gravity direction of the sterilization box 100 is perpendicular to the rotation buckling direction of the first reverse buckling structure and the second reverse buckling structure, and the gravity of the sterilization box 100 cannot make the sterilization box 100 separate from the mounting seat 200, so there is no need to pay attention to the relative position relationship between the two grooves and the inner container, reducing the requirement for assembly accuracy.

[0107] Furthermore, as Figure 7 , Figure 8 shown, a second reverse buckling structure is formed by the inner concavity at one end of the groove, that is, the second reverse buckling structure is hidden on one side of the groove.

[0108] Specifically, as Figure 7 , Figure 8 , Figure 9As shown, the first mounting portion 510 includes a first rib 511 with a first undercut 513 at one end, and a second rib 512 with a second undercut 514 at one end. The first rib 511 is rotationally symmetrical with the second rib 512. The first undercut 513 and the second undercut 514 are respectively located at the opposite ends of the first rib 511 and the second rib 512. The second mounting portion 520 includes a first groove 521 with one end concave to form a third undercut 523, and a second groove 522 with one end concave to form a fourth undercut 524. When installing the sterilization box 100, align the side of the sterilization box 100 provided with the first groove 521 and the second groove 522 with the side of the mounting seat 200 provided with the first convex rib 511 and the second convex rib 512, until the first convex rib 511 and the second convex rib 512 of the mounting seat 200 respectively extend into the corresponding first groove 521 and the second groove 522 of the sterilization box 100, and rotate toward the direction of the third inverted buckle 523 and / or the fourth inverted buckle 524 until the first inverted buckle 513 and the second inverted buckle 514 are respectively inserted into the third inverted buckle 523 and the fourth inverted buckle 524, so that the first inverted buckle 513 and the second inverted buckle 514 are respectively engaged with the third inverted buckle 523 and the fourth inverted buckle 524, and the installation of the sterilization box 100 is completed. Furthermore, the inner contour of the third inverted buckle 523 in the shape of a slot wraps around the outer contour of the first inverted buckle 513, and the inner contour of the fourth inverted buckle 524 in the shape of a slot wraps around the outer contour of the second inverted buckle 514, so that when the sterilization box 100 is rotated without external force, the sterilization box 100 cannot be detached from the mounting seat 200, ensuring that the sterilization box 100 is firmly installed and does not fall off easily during use.

[0109] Example 2

[0110] The present invention provides a refrigerator, including a refrigerator body, wherein the inner wall of the inner tank 2 of the refrigerator body is provided with a household appliance sterilization module as described above. Figure 1 , Figure 11 , Figure 12 As shown, a second through groove 201 is provided on the top inner wall of the inner tank 2. First, the wiring terminal 300 is plugged into the first through groove 211 of the base 210 of the mounting base 200 of the sterilization module body 1, and then the residual detection device 400 is plugged into the interface of the first end 310 of the wiring terminal 300. The base 210 is pre-buried on the side of the inner tank 2 away from the storage area of ​​the refrigerator body, and the base 210 covers the second through groove 201 of the inner tank 2 to prevent foaming and overflow; then the fixing base 220 is fixed to the side of the base 210 facing the storage area of ​​the refrigerator body by screws 230 to complete the installation of the mounting base 200. The sterilization box 100 is then rotated and snapped onto the fixing seat 220 of the mounting seat 200 toward the side of the refrigerator storage area to complete the installation of the sterilization box 100. When sterilization needs to be activated, an external force drives the piercing end of the piercing structure body 150 to approach the partition layer 130 until the partition layer 130 is pierced, so that the first reactant contacts the second reactant and reacts to generate a volatile sterilant.

[0111] Compared with the prior art, the household appliance sterilization module provided by the present invention enables the first reactant in the first chamber to contact and react with the second reactant in the second chamber through the puncturing structure body to generate a volatile bactericide for sterilizing the household appliance box body. The structure that directly stores the volatile bactericide is replaced by the volatile bactericide generating structure, which increases the amount of the volatile bactericide that can be provided by the sterilization module body and extends the sterilization time limit.
