a plurality of first vents 140 and a piercing structure body 150;
the piercing structure body 150 is used for piercing the separation layer 130, so that the first reactant and the second reactant are mixed and react to generate a volatile bactericide, and the volatile bactericide overflows from the first air vents 140 into the household appliance box body for sterilization. In one embodiment, the piercing structural body 150 is driven by the driving assembly to move to the separation layer 130 and pierce the separation layer 130; in yet another embodiment, the lancet body 150 is rotated to move the lancet body 150 to the separation layer 130 and puncture the separation layer 130.
In one embodiment, the volatile sterilant is chlorine dioxide gas. Chlorine dioxide is a broad-spectrum, high-efficiency and nontoxic sterilizing disinfectant, has the advantages of low effective concentration and high action speed, and is widely applied to sterilizing disinfectors and food preservatives. Chlorine dioxide gas can be generated by reacting a solid-phase reactant with a liquid-phase reactant, such as chlorite in a solid phase and an acidic reactant in a liquid phase, such as sodium chlorite in a solid phase and hydrochloric acid in a liquid phase.

In another embodiment, when the residual amount detection device 400 detects that the residual amount of chlorine dioxide in the chlorine dioxide gel in the sterilization box 100 is nearly exhausted, the alarm module gives an alarm, a threshold value of the alarm condition of the alarm module is preset, the residual amount of chlorine dioxide in the chlorine dioxide gel detected by the residual amount detection device 400 meets the threshold value, and the control board sends an alarm instruction to the alarm module when the detected residual amount of chlorine dioxide in the chlorine dioxide gel reaches the threshold value. It should be understood that the volatile sterilant could be a gel containing other sterilant volatiles having a color and that the present invention is not described in detail herein. Further, the remaining amount detecting device 400 is a turbidity sensor, and detects a color change of the chlorine dioxide gel in the sterilizing box 100 through the transparent area of the sterilizing box 100 to determine the remaining amount of chlorine dioxide contained in the chlorine dioxide gel, and further determine the remaining amount of chlorine dioxide volatile matter released from the chlorine dioxide gel into the sterilizing box 100.

The first end 310 of the connection terminal 300 passes through the first through groove 211 from the side of the base 210 departing from the storage area of the household appliance cabinet, the first end 310 of the connection terminal 300 extends into the side of the base 210 facing the storage area of the household appliance cabinet, and the second end 320 of the connection terminal 300 is located at the side of the base 210 departing from the storage area of the household appliance cabinet, so that the allowance 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 cabinet, and then the allowance detection device 400 is installed on the base 210 and connected with the connection terminal 300. Further, the inner contour of the first through groove 211 abuts against the circumferential contour of the first end 310 of the connection terminal 300, so that the first end 310 of the connection terminal 300 is clamped in the first through groove 211, and the connection terminal 300 is further mounted on the base 210.
Further, as shown in fig. 1, the outer contour of the side of the first through groove 211 departing from the storage area of the household appliance box body abuts against the side of the second end 320 of the connection terminal 300 facing the storage area of the household appliance box body, so that the first through groove 211 is sealed by the side of the second end 320, and when the household appliance box body is foamed, the foaming material does not overflow from the first through groove 211.
In an embodiment, as shown in fig. 5, a fastening structure 212 for fixing the remaining-amount detecting device 400 is disposed on a side of the base 210 facing the storage area of the household electrical appliance housing. The engaging structure 212 engages with a first engaging protrusion 410 of the residue detecting device 400 to limit the movement of the residue detecting device 400 in the direction away from the connecting terminal 300, so as to fix the residue detecting device 400 to a certain extent. Further, after the allowance detection device 400 is inserted into the interface of the first end 310 of the connection terminal 300, and the fastening structure 212 fastens the first fastening protrusion 410 of the allowance detection device 400, the sidewall of the base 210 having the first through groove 211 abuts against one side of the allowance detection device 400 to limit the movement of the allowance detection device 400 along the direction toward the connection terminal 300, so as to firmly fix the allowance detection device 400. The remaining amount detecting means 400 is opposite to the transparent region of the sterilizing box 100 through the second through groove 201 provided in the inner container 2, the sterilizing box 100 is positioned at a side of the base 210 facing the storage region of the home appliance case, and the remaining amount detecting means 400 detects the remaining amount of chlorine dioxide gas in the sterilizing box 100 through the transparent region of the sterilizing box 100.
Further, as shown in fig. 1, the fixing base 220 and the base 210 form a cavity for accommodating the allowance detection device 400, and the fixing base 220 is configured to cover the allowance detection device 400, so as to prevent the allowance detection device 400 from being exposed in the storage area of the household appliance box body and affecting the overall aesthetic degree of the interior of the household appliance box body.

In an embodiment, as shown in fig. 1 and 12, the fixing base 220 covers an outer contour of one side of the base 210 facing the second through slot 201 to cover the base 210 pre-embedded in the inner container 2, so as to modify an inner wall of the inner container 2, so as to improve the tidiness of the inner wall of the inner container 2.
In one embodiment, as shown in fig. 1, the fixing base 220 is fixed to the base 210 by a screw 230.

The inner walls of the first and second recesses 213 and 222 are fixed by screws 230, which seal the assembly holes of the first and second recesses 213 and 222 to prevent foaming of flash from the assembly holes. Further, one end of the sterilizing box 100 extends into the second recess 222 of the fixing seat 220, and the sterilizing box 100 is accommodated in the second recess 222, so that the sterilizing box 100 is not obtrusive after being installed on the inner container 2, and has a small and compact structure.
Further, as shown in fig. 1 and 3, the base 210 has a first abutting portion 214 for abutting against the outer wall of the inner container 2 away from the storage area of the household appliance box. Further, the first contact portion 214 is bonded to one outer wall of the inner container 2 to fix the base 210 to the inner container 2. The outer contour of one side of the first abutting part 214 facing the inner container 2 tightly abuts against the inner container 2, so that the bonding area between the first abutting part 214 and the inner container 2 is increased, and the fixing fastness of the base 210 is improved.
Further, as shown in fig. 1 and 3, a space is left between a side wall of the fixing base 220 away from the base 210 and the inner container 2, a side wall of the fixing base 220 away from the base 210 is bent along a direction toward the base 210 to form a second abutting portion 223 for abutting against an outer wall of the inner container 2 on a side toward the storage area of the household appliance box, and 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 appearance of the surface of the inner container 2.
In one embodiment, as shown in fig. 12, the sterilization module body 1 is disposed on the inner wall of the top of the inner container 2. In an embodiment, the sterilization module body 1 is adhered 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 seat 200 and then is mounted on the door liner 2, the base 210 and the inner container 2 are tightly connected through adhesion, the sterilization module body 1 is arranged on the top of the inner container 2, the gravity of the sterilization module body 1 cannot cause the base 210 to be separated from the inner container 2, and the sterilization module body 1 is stably connected with the inner container 2.
In one embodiment, as shown in fig. 1 and 2, the puncture structure body 150, the first chamber 110, the separation layer 130, and the second chamber 120 are sequentially disposed along a direction away from the inner wall of the inner container 2.
In one embodiment, the piercing member body 150 is disposed at one end of the sterilization case 100; the outer surface of the puncture structure body 150 facing the household appliance inner container 2 is provided with a connecting structure which is rotationally buckled on the inner wall of the inner container 2; wherein the content of the first and second substances,
when the sterilizing box 100 is installed, the puncture structure body 150 is rotated to drive the connecting structure to rotate so as to be buckled on the inner wall of the inner container 2, and then the sterilizing box 100 is installed;
when the sterilization case 100 is activated, the piercing member 150 is forced by external force to approach the separation layer 130, so that the piercing end pierces the separation layer 130.
In one embodiment, the piercing member body 150 is disposed in the first chamber 110 of the sterilizing cassette 100; the external force drives the puncturing structure body 150 to approach the separation layer 130 to puncture the separation layer 130, so that the first reactant in the first chamber 110 and the second reactant in the second chamber 120 are mixed and react to generate the volatile bactericide, and the volatile bactericide overflows from the first ventilation port 140 of the sterilizing box 100 to the household appliance box body to sterilize the household appliance box body. Further, a sealing ring 180 is disposed between the piercing body 150 and the inner wall of the first chamber 110 of the sterilizing cassette 100 to prevent the reactant in the first chamber 110 from leaking between the piercing body 150 and the inner wall of the first chamber 110 of the sterilizing cassette 100. The puncturing structure body 150 can be pushed to approach the separation layer 130 of the sterilizing chamber 100 by a manual or mechanical force.
In one embodiment, as shown in fig. 1, the outer wall of the puncturing structure body 150 is provided with external threads on the periphery thereof to be in threaded connection with the inner wall of the first chamber 110, i.e. the puncturing structure body 150 can be screwed in and out of the first chamber 110; rotating the first chamber 110 of the sterilization box 100, and rotating the puncture structure body 150 together, so that the connection structure of the puncture structure body 150 is buckled on the inner wall of the inner container 2 along with the rotation, thereby completing the installation of the sterilization box 100; in one embodiment, the sterilizing cartridge 100 is rotated such that the first chamber 110 rotates together therewith; wherein the content of the first and second substances,
after the sterilization box 100 is rotated to fasten the puncture structure body 150 on the inner wall of the inner container 2, the sterilization box 100 is continuously rotated in the same direction to screw the puncture structure body 150 into the first chamber 110 to approach the separation layer 130 and puncture the separation layer 130, so that the first reactant and the second reactant are mixed and react to generate the volatile bactericide, and the volatile bactericide overflows from the first ventilation port 140 of the sterilization box 100 to the household appliance box body to sterilize the household appliance box body. The rotating direction of the first chamber 110, which is rotatably fastened to the inner wall of the inner container 2 by the puncturing structure body 150, is the same as the rotating direction of the first chamber 110 when the puncturing structure body 150 is screwed into the first chamber 110, so as to prevent the rotating direction of the first chamber 110, which is screwed into the first chamber 110 by the puncturing structure body 150, from being opposite to the rotating direction of the first chamber 110, which is rotatably fastened to the inner wall of the inner container 2 by the puncturing structure body 150, and thus the puncturing structure body 150 is rotated when the puncturing structure body 150 is started to disengage from the fastening of the inner wall of the inner container 2, and the sterilization box 100 falls. When the puncture structure body 150 is designed, the rotation angle of the puncture structure body 150 (i.e., the first chamber 110) rotationally locked on the inner wall of the liner 2 and the rotation angle of the first chamber 110 when the separation layer 130 is punctured can be specifically limited, so as to facilitate installation and opening of puncturing. For example, the puncturing structure body 150 is rotated by 15 ° to fasten the puncturing structure body 150 to the inner wall of the inner container 2, so as to complete the installation of the sterilizing box 100, and the first chamber 110 is rotated by 180 ° in the same direction, so that the puncturing structure body 150 punctures the separating layer 130. Because the puncture structure body 150 is fixed on the inner wall of the inner container 2, and the continuous rotation direction of the first chamber 110 is the same as the rotation direction of the puncture structure body 150 when being fastened to the inner wall of the inner container 2, when the first chamber 110 is continuously rotated in the same direction, the puncture structure body 150 is tightly fastened to the inner wall of the inner container 2, that is, the puncture structure body 150 does not move relative to the inner wall of the inner container 2, but moves in a screw-in manner relative to the first chamber 110, and finally punctures the separation layer 130.
In one embodiment, the volatile germicide is chlorine dioxide gas, and is generated by the reaction of a solid-phase reactant and a liquid-phase reactant, and the space occupied by the solid-phase reactant is smaller than that occupied by the liquid-phase reactant. The periphery of the piercing structural body 150 is screwed to the inner wall of the first chamber 110, and in order to save cost, the volume of the piercing structural body 150 should not be too large, and the space of the first chamber 110 should not be too large, so that the first chamber 110 is preferably used to store the solid first reactant, and the second chamber 120 is used to store the liquid second reactant. Further, the second chamber 120 surrounds the outer peripheral side of the first chamber 110, and the accommodating space of the second chamber 120 is increased to some extent. The puncture structure body 150, the inner wall of the first chamber 110, and the separation layer 130 form a space for accommodating a first reactant, and when the sterilization box 100 is installed, the sterilization box 100 is rotated such that the first chamber 110 drives the puncture structure body 150 to rotate together, and further, the puncture structure body, the inner wall of the first chamber 110, and the separation layer 130 are rotationally fastened on the fixing base 220; continuing to rotate the sterilization case 100 in the same direction, since the piercing body 150 is fixed by the base 210 without moving, the first chamber 110 rotates relative to the piercing body 150, so that the piercing body 150 is screwed into the first chamber 110 until the separating layer 130 is pierced. In one embodiment, the sterilization module body 1 is disposed on the inner wall of the top of the inner container 2, and the first chamber 110 is located above the second chamber 120, when the separation layer 130 is punctured, the first reactant in the first chamber 110 falls into the second chamber 120 under gravity, and then mixes with the second reactant in the second chamber 120 to trigger the reaction. Due to the gravity assist, the mixing speed of the first reactant and the second reactant is accelerated, the amount of the first reactant remaining in the first chamber 110 is reduced, and the amount of the volatile germicide generated is increased.
Specifically, as shown in fig. 1 and 2, the first chamber 110 of the sterilizing cassette 100 is disposed in the end cap 101, and the second chamber 120 is disposed in the cassette body 102. The end cap 101 is provided with a cylindrical protrusion facing the box body 102, a hollow portion is provided in the protrusion, an inner wall of the hollow portion of the end cap 101 is provided with an internal thread for being in threaded connection with the puncturing structure body 150, the puncturing structure body 150 seals one side of the hollow portion of the end cap 101, which is far away from the box body 102, and the separation layer 130 seals one side of the hollow portion of the end cap 101, which faces the box body 102, so as to form the first chamber 110. The case 102 is recessed toward the end cap 101 to form a cavity, and the sidewall of the case 102 abuts against the surface of the end cap 101 facing the case 102, and then the communicating portion between the case 102 and the end cap 101 is sealed by the partition 130 to form the second chamber 120. In one embodiment, the connection of the end cap 101 to the case 102 includes, but is not limited to, snap connection, screw connection, and ultrasonic welding.
Further, when the sterilization case 100 is disposed on the top of the inner container 2, the first reactant in the solid phase in the first chamber 110 of the cap 101 falls into the second chamber 120 of the case 102 to react with the second reactant in the liquid phase after the separation layer 130 is pierced by the piercing structure body 150. When the sterilization box 100 is disposed on the sidewall of the inner container 2, after the piercing structure body 150 pierces the separation layer 130, since the first chamber 110 of the end cap 101 extends into the cavity of the box body 102, that is, the first reactant in the first chamber 110 is not blocked by the sidewall structure of the separation layer 130, the first reactant in the first chamber 110 slides into the second chamber 120 of the box body 102 to react with the second reactant in liquid phase.
Further, the case 102 is transparent, and when the remaining amount detecting device 400 is mounted, the remaining amount detecting device 400 faces the sidewall of the case 102, and detects the remaining amount of the volatile germicide generated in the second chamber 120 of the case 102 through the case 102.
Further, the first ventilation opening 140 is disposed on the bottom wall of the box 102, and the cover 170 is connected to the box 102 in a snap-fit manner. Specifically, the box body 102 is provided with at least two second clamping grooves 1021, the cover 170 is provided with a second clamping protrusion 172 matched with the second clamping grooves 1021, and the cover 170 and the box body 102 are detachably connected by clamping the second clamping protrusion 172 into the second clamping grooves 1021. Furthermore, the box body 102 is provided with four second clamping grooves 1021, the four second clamping grooves 1021 are distributed annularly, and the cover 170 is provided with four second clamping protrusions 172, so as to improve the clamping firmness between the cover 170 and the box body 102.
The piercing body 150 is cylindrical, and the outer contour of the piercing body 150 abuts against the inner contour of the first chamber 110, so as to prevent the reactant stored in the sterilization case 100 from leaking from the connection between the piercing body 150 and the first chamber 110.
In one embodiment, as shown in FIGS. 1 and 6, the piercing end comprises a plurality of first sharp corners 151 disposed on the end surface of the piercing structure body 150 facing the separation layer 130, so that the piercing structure body 150 pierces the separation layer 130. Further, the plurality of first sharp corners 151 are arranged in an annular array, and along with the rotation of the piercing structural body 150, the plurality of first sharp corners 151 exert piercing force on the separation layer 130 along the track of the circumference where the first sharp corners 151 are located, so as to enlarge the opening torn by the separation layer 130, and improve the mixing speed of the first reactant in the first chamber 110 and the second reactant in the second chamber 120.
In one embodiment, as shown in fig. 1, the first sharp corner 151 faces the junction of the separation layer 130 and the inner contour of the first chamber 110 to pierce the separation layer 130 to separate the separation layer 130 from the junction of the inner contour of the first chamber 110, i.e., to completely expose the opening of the first chamber 110 facing the second chamber 120, 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, and simultaneously to completely mix the first reactant and the second reactant, thereby increasing the utilization rate of the reaction material.
In one embodiment, as shown in fig. 1 and 6, the piercing structural body 150 is a hollow structure; the piercing end includes a second sharp corner 152 disposed axially within the hollow region of the lancing structure body 150. Further, the second sharp corner 152 points toward the center of the spacer layer 130 to act simultaneously with the first sharp corner 151 to accelerate the piercing of the spacer layer 130.
In an embodiment, as shown in fig. 1 and 6, a first engaging groove 153 for engaging the sealing ring 180 is disposed at an end of the piercing structural body 150 near the separating layer 130, and after the first engaging groove 153 engages the sealing ring 180, the sealing property between the piercing structural body 150 and the inner wall of the first chamber 110 is improved, so as to prevent the first reactant and/or the second reactant in the sterilization box 100 from overflowing from a joint between the piercing structural body 150 and the inner wall of the first chamber 110 to the outside of the sterilization box 100, which results in waste of raw materials and reduced safety in use.
In one embodiment, as shown in fig. 7, 8 and 9, the piercing structural body 150 is provided with a second mounting portion 520, and the fixing seat 220 of the mounting seat 200 provided on the sterilization module body 1 is provided with a first mounting portion 510; the first mounting portion 510 and the second mounting portion 520 are locked together by a reverse locking structure after being locked into the groove by the rib. When the sterilizing box 100 needs to be removed from the inner container, the puncturing structure body 150 is rotated reversely to disengage from the inner wall of the inner container 2.
Further, in one embodiment, the ribs of the first mounting portion 510 are disposed separately from the corresponding first inverted structure, and the grooves of the second mounting portion 520 are disposed separately from the corresponding second inverted structure. After the rib of the first mounting portion 510 extends into the groove of the second mounting portion 520, the rib can rotate in the groove or rotate for a certain distance until the first and second inverted structures are fastened together. Wherein, the convex rib and the groove play a role in auxiliary positioning, and the installation speed is improved. Further, the first reverse-buckling structure and the second reverse-buckling structure are buckled with each other, and the groove of the second installation part 520 has a limiting effect on the convex rib of the first installation part 510, so that the first reverse-buckling structure and the second reverse-buckling structure are prevented from being separated from being buckled due to continuous co-rotation.
In another embodiment, the second mounting portion 520 includes two arc-shaped grooves respectively provided with the second reverse-buckling structures; the two ribs of the first mounting portion 510, which are respectively provided with the first reverse-buckling structures, respectively extend into the two grooves of the second mounting portion 520, and the first reverse-buckling structures and the second reverse-buckling structures are matched with each other by rotation. In one embodiment, the two grooves of the second mounting portion 520 have different arcs, and the two grooves are located on the same circumference, so that the larger and smaller structure of the two grooves can prevent the user from being confused, for example, the puncturing structure body 150 is rotated along the direction of the larger groove to the smaller groove, which is the direction of mounting the sterilizing box 100, and the opposite direction is the direction of detaching the sterilizing box 100. In another embodiment, the two grooves are rotationally symmetrical, the arcs of the two grooves are the same in length, and the two grooves which are rotationally symmetrical are convenient to machine. It should be understood that the length of the arc of the groove provided by the second mounting portion 520 is slightly longer than the length of the arc of the convex rib provided by the first mounting portion 510, that is, the convex rib provided with the first reverse-buckling structure can be smoothly clamped into the matched groove, when the first reverse-buckling structure and the second reverse-buckling structure are buckled by rotation, a gap is left between one side wall of the groove far away from the reverse-buckling connection and one end of the convex rib provided correspondingly far away from the reverse-buckling connection, and the gap is not large, which is not enough to easily separate the first mounting portion 510 from the second mounting portion 520. After the second reverse-buckling structure of the second mounting portion 520 is buckled with the first reverse-buckling structure correspondingly arranged on the first mounting portion 510, a gap between one side wall of the groove far away from the reverse-buckling connection and one end of the corresponding convex rib far away from the reverse-buckling connection is increased, so that the puncture structure body 150 can be smoothly detached from the first mounting portion 510 when the puncture structure body 150 is punctured in a reverse rotation manner. Wherein, the arc distance of increase is the arc length of first back-off structure and/or second back-off structure, and further, first back-off structure is the same with second back-off structure arc length.
Further, the second reverse-buckling structure of the second mounting portion 520 of the puncture structure body 150 is disposed 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 in the rotating direction when the groove is buckled, when the second reverse-buckling structure is buckled with the first reverse-buckling structure on the inner wall of the inner container 2, the sterilizing box 100 is hung on the inner wall of the inner container 2, and when no external force reversely rotates, the second reverse-buckling structure and the first reverse-buckling structure cannot be separated from a buckling state. It should be understood that when the sterilizing cassette 100 is installed, the two grooves are positioned such that the first and second reverse fastening structures are fastened without being separated from each other by the gravity of the sterilizing cassette 100. Preferably, the sterilizing box 100 is installed on the top of the inner container, the gravity direction of the sterilizing box 100 is perpendicular to the rotating and locking directions of the first and second reversing structures, and the gravity of the sterilizing box 100 cannot make the sterilizing box 100 separate from the mounting base 200, so that the relative position relationship between the two grooves and the inner container does not need to be concerned, and the requirement for assembly accuracy is reduced.
Further, as shown in fig. 7 and 8, one end of the groove is recessed to form a second inverse-buckling structure, i.e., the second inverse-buckling structure is hidden at one side of the groove.
Specifically, as shown in fig. 7, 8, and 9, the first mounting portion 510 includes a first rib 511 having a first inverted buckle 513 at one end thereof and a second rib 512 having a second inverted buckle 514 at one end thereof, the first rib 511 and the second rib 512 are rotationally symmetric, and the first inverted buckle 513 and the second inverted buckle 514 are respectively located at opposite ends of the first rib 511 and the second rib 512. The second mounting portion 520 includes a first recess 521 having one end recessed to form a third undercut 523, and a second recess 522 having one end recessed to form a fourth undercut 524. When the sterilizing box 100 is installed, one side of the sterilizing box 100, which is provided with the first groove 521 and the second groove 522, is aligned with one side of the mounting base 200, which is provided with the first rib 511 and the second rib 512, until the first rib 511 and the second rib 512 of the mounting base 200 respectively extend into the first groove 521 and the second groove 522, which are correspondingly arranged, of the sterilizing box 100, and rotate towards the direction of the third inverse buckle 523 and/or the fourth inverse buckle 524, until the first inverse buckle 513 and the second inverse buckle 514 are respectively clamped into the third inverse buckle 523 and the fourth inverse buckle 524, so that the first inverse buckle 513 and the second inverse buckle 514 are respectively buckled with the third inverse buckle 523 and the fourth inverse buckle 524, and the installation of the sterilizing box 100 is completed. Further, the inner contour of the third reverse buckle 523 in the shape of a clamping groove wraps the outer contour of the first reverse buckle 513, and the inner contour of the fourth reverse buckle 524 in the shape of a clamping groove wraps the outer contour of the second reverse buckle 514, so that when the sterilizing box 100 is rotated without an external force, the sterilizing box 100 cannot be separated from the mounting base 200, and the sterilizing box 100 is ensured to be stably mounted and not easily fall off in the using process.
