[0007] In one embodiment, the outer shell includes a main shell and an upper cover. The high-voltage package, the fan, the first electrode plate, the second electrode plate and the catalyst assembly are installed in the main shell. The upper cover is snapped with the main shell and forms an air inlet and an air outlet between the upper cover and the main shell. The air inlet is arranged opposite to the first electrode plate, and the air outlet is connected to the outlet of the fan.

[0008] In one of the embodiments, the air inlet is configured as a hollow plate.

[0009] In one of the embodiments, a plurality of rows of hole groups are provided on the hollow plate, and the plurality of rows of hole groups are arranged along the height direction of the hollow plate, and each row of hole groups includes a plurality of via holes arranged at intervals along the length direction of the hollow plate; and along the length direction of the hollow plate, the via holes of two adjacent rows of hole groups are staggered with each other.

In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0030] See also Figures 1 to 5 The present application provides a sterilization and deodorization device 100, which includes a housing 50, a fan 20 and an electric wire 22. The fan 20 is installed inside the housing 50, and a winding post 23 is provided inside the housing 50. The electric wire 22 extends from one side of the housing 50 into the housing 50 and extends along a preset direction. Then, the electric wire 22 is wound around the winding post 23 and extends in a direction opposite to the preset direction, and is connected to the fan 20. In actual use, the preset direction is the direction of gravity. In this way, when water droplets in the external environment enter the housing 50 along the electric wire 22, the water droplets will detach from the electric wire 22 at a position close to the winding post 23 under the action of their own gravity and drip on the bottom of the housing 50, instead of continuing to move up along the electric wire 22 into the fan 20, thereby helping to reduce the risk of damage to the fan.

[0031] The sterilization and deodorization device 100 further includes a high-voltage package 10, a first electrode plate 31, a second electrode plate 32, and a catalyst assembly 40 installed inside the housing 50, wherein the catalyst assembly 40 is located between the first electrode plate 31 and the second electrode plate 32. The fan 20 and the high-voltage package 10 are both located on the side of the second electrode plate 32 away from the first electrode plate 31, the high-voltage package 10 is electrically connected to the first electrode plate 31 and the second electrode plate 32, and the high-voltage package 10 has a first air guide surface 11, which is arranged at an angle with the second electrode plate 32 and is used to guide air to flow toward the fan 20; wherein a high-voltage discharge area is formed between the first electrode plate 31 and the second electrode plate 32 and plasma is generated, and air flows from the first electrode plate 31 to the second electrode plate 32 and carries plasma to the fan 20.

[0032] It can be understood that the first electrode plate 31 is the air inlet side, the second electrode plate 32 is the air outlet side, and the fan 20 and the high-voltage package 10 are arranged on the air outlet side. In addition, the fan 20 provides suction wind force, so that more air flows from the first electrode plate 31 to the second electrode plate 32, and the first air guide surface 11 on the high-voltage package 10 is used to guide the air flowing out of the second electrode plate 32 to the fan 20, which is conducive to reducing the energy loss during the air flow process.

[0033] An angle α is formed between the first wind guide surface 11 and the second electrode plate 32, and the opening of the angle α is set toward the fan 20, and 10°≤α≤30°. It can be understood that if α is too small, the air flowing out of the second electrode plate 32 is approximately blown vertically to the first wind guide surface 11, which will increase the wind resistance. If α is too large, the first wind guide surface 11 loses the effect of guiding the air. Therefore, setting 10°≤α≤30° is conducive to reducing wind resistance, thereby reducing energy loss during air circulation. Optionally, the value of α can be 10°, 15°, 16°, 17°, 17.5°, 29°, 25°, 30°, etc., which can be based on actual needs and are not listed here one by one.

[0034] Specifically, the high-voltage package 10 is arranged to be inclined relative to the second electrode plate 32 , so that a side wall of the high-voltage package 10 forms a first air guide surface 11 .

[0035] The housing 50 includes a main housing 51 and an upper cover 52. The high-voltage package 10, the fan 20, the first electrode plate 31, the second electrode plate 32 and the catalyst assembly 40 are installed in the main housing 51. The upper cover 52 is engaged with the main housing 51, and an air inlet 53 and an air outlet 54 are formed between the upper cover 52 and the main housing 51. The air inlet 53 is arranged opposite to the first electrode plate 31, and the air outlet 54 is connected to the outlet of the fan 20. It can be understood that the air flow path in the sterilization and deodorization device 100 is: first electrode plate 31-catalyst assembly 40-second electrode plate 32-fan 20-air outlet 54.

[0036] In one embodiment, the air inlet 53 is configured as a hollow plate.

[0037] Furthermore, the hollow plate is provided with multiple rows of hole groups 531, which are arranged along the height direction of the hollow plate, and each row of hole groups 531 includes multiple through holes 532 arranged at intervals along the length direction of the hollow plate; and along the length direction of the hollow plate, the through holes 532 of two adjacent rows of hole groups 531 are staggered. In this way, the air can smoothly pass through the air inlet 53 while ensuring the structural strength of the hollow plate. The sizes of the multiple through holes 532 can be the same or different.

[0038] Along the direction from the inside of the main shell 51 to the outside of the main shell 51 , the air outlet 54 is in an expanded trumpet shape to facilitate the air to be discharged smoothly from the air outlet 54 .

[0039] See also Figure 6 to Figure 7 ,in, Figure 6 A top view of the sterilization and deodorization device 100 provided in the present application; Figure 7 for Figure 6 Cross-sectional view at AA. The upper cover 52 has a second air guide surface 521, which is located between the second electrode plate 32 and the inlet of the fan 20 along the air flow direction, and the second air guide surface 521 is arranged at an angle with the second electrode plate 32, and is used to guide the air flowing out of the second electrode plate 32 to flow toward the inlet of the fan 20. By providing the second air guide surface 521, it is helpful to further reduce the wind resistance in the process of air flowing from the second electrode plate 32 to the fan 20.

[0040] Specifically, Figure 7 As shown, along the thickness direction of the sterilization and deodorization device 100, the inlet of the fan 20 is arranged upward, the height of the upper cover 52 located above the second electrode plate 32 is less than the height of the upper cover 52 located above the fan 20, and along the direction from the second electrode plate 32 to the fan 20, the height of the second air guide surface 521 gradually increases to facilitate guiding the air flowing out of the second electrode plate 32 upward to the inlet of the fan 20.

[0041] like Figure 3 As shown, the sterilization and deodorization device 100 also includes a connecting line 12. The first electrode plate 31 serves as a high-voltage electrode and is connected to the negative output end of the high-voltage package 10 through the connecting line 12. The second electrode plate 32 serves as a grounding electrode, and high voltage discharge is performed from the first electrode plate 31 to the second electrode plate 32.

[0042] like Figure 5 and Figure 7As shown, the first electrode plate 31 and the second electrode plate 32 are respectively provided with a first through hole 312, and the catalyst assembly 40 is provided with a second through hole 41, and the second through hole 41 is correspondingly arranged and connected with the first through hole 312. The first through hole 312 and the second through hole 41 are used for air circulation, and a high-voltage discharge channel is formed between the first electrode plate 31 and the second electrode plate 32 via the second through hole 41, so as to facilitate the generation of more plasma in the high-voltage discharge channel.

[0043] The catalyst assembly 40 includes a ceramic substrate 42 and a catalyst coating coated on the ceramic substrate 42, and the second through hole 41 is opened on the ceramic substrate 42. The catalyst coating is used to accelerate the decomposition of odor molecules, prolong the reaction time with the odor molecules and enhance the deodorization effect.

[0044] See also Figure 4 , Figure 5 and Figure 7 The main shell 51 is provided with two card slots 55, and the first electrode plate 31 and the second electrode plate 32 are respectively clamped in the corresponding card slots 55. The ends of the first electrode plate 31 and the second electrode plate 32 close to the upper cover 52 are respectively provided with flanges 311, and the upper cover 52 is crimped to the flanges 311. The flanges 311 are provided to increase the contact area between the first electrode plate 31 and the second electrode plate 32 and the upper cover 52, so as to avoid the shaking of the first electrode plate 31 and the second electrode plate 32 after assembly. Specifically, in the process of assembling the sterilization and deodorization device 100, the first electrode plate 31 and the second electrode plate 32 can be respectively inserted into the corresponding card slots 55, and then the upper cover 52 is crimped onto the flanges 311 from top to bottom, and the upper cover 52 is buckled together with the main shell 51.

[0045] Optionally, in one embodiment, a plurality of card block groups 551 are provided on the bottom wall of the main housing 51, and the plurality of card block groups 551 are arranged at intervals along the length direction of the first electrode plate 31 or the second electrode plate 32, and each card block group 551 includes two opposite and spaced card blocks 552, and the first electrode plate 31 or the second electrode plate 32 is clamped between the two oppositely arranged card blocks 552 along its thickness direction. That is, in this embodiment, the card slot 55 is defined by the plurality of card block groups 551. Of course, in other embodiments, the card slot 55 can also be directly opened on the bottom wall of the main housing 51.

[0046] The flange 311 extends in a direction away from the first electrode plate 31 and the second electrode plate 32. Along the direction from the first electrode plate 31 to the second electrode plate 32, the distance between the second air guide surface 521 and the bottom wall of the main housing 51 gradually increases, and the second air guide surface 521 is provided with an abutment block 522, and the second air guide surface 521 is pressed against the flange 311 through the abutment block 522. Since the second air guide surface 521 and the second electrode plate 32 are arranged at an angle, it is difficult for the second air guide surface 521 to be directly pressed against the flange 311. By providing the abutment block 522, it is convenient for the second air guide surface 521 to be pressed against the flange 311 through the abutment block 522.

[0047] The sterilization and deodorization device 100 further includes a first buffer pad 61, which is attached to the surface of the ceramic substrate 42 close to the upper cover 52; and / or, the first buffer pad 61 is attached to the lower surface of the ceramic substrate 42 close to the bottom wall of the main housing 51. The first buffer pad 61 is used to protect the ceramic substrate 42 to prevent the ceramic substrate 42 from being broken. Optionally, the first buffer pad 61 is configured as a shock-absorbing sponge or a rubber pad.

[0048] See also Figure 6 The sterilization and deodorization device 100 further includes a second buffer pad 62 and an elastic shock-absorbing member 70. A plug-in column 56 is provided on the main housing 51. The fan 20 is provided with an assembly hole 21. The plug-in column 56 is inserted into the assembly hole 21. One end of the elastic shock-absorbing member 70 is inserted into the assembly hole 21, and the other end is abutted against the upper cover 52. The second buffer pad 62 is attached to the side of the fan 20 close to the main housing 51. The plug-in column 56 is provided to realize a detachable connection with the main housing 51, and the fan 20 can be conveniently installed on the main housing 51. In addition, the second buffer pad 62 can prevent the lower surface of the fan 20 from hard contact with the main housing 51, and the elastic shock-absorbing member 70 can prevent the upper surface of the fan 20 from hard contact with the upper cover 52, thereby reducing the noise generated during the operation of the fan 20. Among them, the elastic shock-absorbing member 70 can be configured as a rubber plug.

[0049] See also Figure 3 and Figure 4 The main housing 51 is also provided with a plurality of limiting ribs 57, which are spaced along the edge of the high-voltage package 10, and the high-voltage package 10 is clamped between the plurality of limiting ribs 57. The plurality of limiting ribs 57 cooperate to play a positioning role, so that the high-voltage package 10 can be accurately installed at a preset position of the main housing 51, so that the first air guide surface 11 on the high-voltage package 10 and the second electrode plate 32 maintain a suitable angle.

[0050] Furthermore, at least part of the end of the limiting rib 57 is spaced apart from the side wall of the main housing 51 and surrounds the wiring groove 511, and the wiring groove 511 is used to accommodate the wires 22. In this way, the shaking of the wires 22 inside the housing 50 can be reduced.

[0051] The sterilization and deodorization device 100 further includes a fastening screw, and a plurality of mounting posts 58 are further provided on the main housing 51, and the mounting posts 58 are provided with threaded holes. The high-pressure package 10 is provided with a mounting plate 13, and the mounting plate 13 and the upper cover 52 are provided with through holes corresponding to the threaded holes, respectively. The mounting plate 13 is sandwiched between the upper cover 52 and the mounting posts 58, and the through holes are connected to the threaded holes. The fastening screws sequentially pass through the two through holes and are threadedly connected to the threaded holes of the mounting posts 58. In this way, the upper cover, the mounting plate 13 and a corresponding mounting post 58 can be connected together using only one fastening screw, which is conducive to saving parts.

[0052] The present application also provides a refrigerator, which includes the sterilization and deodorization device 100 described in any one of the above embodiments.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
