The sterilizing and deodorizing device provided by the embodiment of the utility model can be applied to a refrigerator, but the sterilizing and deodorizing device is not limited to the sterilizing and deodorizing device, and can be applied to occasions and equipment needing deodorizing and purifying, such as a deodorizing device, a purifier, a fresh-keeping warehouse and the like.

Referring to fig. 1 to 6, a first aspect of an embodiment of the present utility model provides a sterilizing and deodorizing device comprising a housing 10, a blower 20, and a sterilizing and deodorizing assembly 30.

The casing 10 has an air inlet 101 and an air outlet 102, and a ventilation duct is formed in the casing 10, and is respectively communicated with the air inlet 101 and the air outlet 102, wherein the air inlet 101 has a plurality of air inlet directions, or the air outlet 102 has a plurality of air outlet directions, and at least two different air inlet directions or two different air outlet directions exist.

The air inlet 101 has a plurality of air inlet directions, which may be that a plurality of air inlets 101 are arranged on the shell 10, so that the air inlet directions of each air inlet 101 are different, thereby realizing that the air inlet 101 has a plurality of air inlet directions; it is also possible to provide a relatively large air inlet 101 on the housing 10, and to provide a plurality of different air inlet directions for one air inlet 101 by means of a plurality of fan interferences provided at the air inlet 101.

The air outlet 102 has a plurality of air outlet directions, which may be the same as the arrangement of the air inlet 101 having a plurality of air inlet directions. Compared with the prior art, the sterilizing and deodorizing device for deodorizing the refrigerator adopts a mode of air inlet and air outlet, and at least two different air inlet directions exist, so that the air in different directions can enter the sterilizing and deodorizing device simultaneously; at least two different air outlet directions exist, so that the sterilizing and deodorizing device can outlet air from different directions, and the purifying area is increased.

The fan 20 is arranged in the ventilation air duct and can drive air to flow from each air inlet 101 to the air outlet 102 along the ventilation air duct; the sterilizing and deodorizing component 30 is arranged in the ventilation air duct, and when air flows from each air inlet 101 to the air outlet 102 along the ventilation air duct, the air is discharged from the air outlet 102 after being deodorized by the sterilizing and deodorizing component 30, so that the aim of sterilizing and deodorizing is fulfilled.

It can be understood that by setting the air inlet in multiple directions or the air outlet in multiple directions, the embodiment of the utility model ensures that two different air inlet directions or two different air outlet directions exist, so as to disturb the air flow in the inner space and the outer space of the sterilizing and deodorizing device, so that the air flow in the inner space and the outer space of the sterilizing and deodorizing device is disturbed, the deodorizing area of the sterilizing and deodorizing device is increased, and further, a good deodorizing effect is realized.

As shown in fig. 1, 2, 3 and 6, three air inlets 101 and one air outlet 102 may be provided on the housing 10 to implement three air inlets and one air outlet of the housing 10. In addition, a ventilation duct is formed inside the housing 10, and is communicated with each of the air inlets 101 and the air outlets 102;

in other words, at least two air inlets 101 are disposed on the housing 10, that is, at least two air inlets 101 are disposed on the housing 10, and of course, more than two air inlets 101 may be disposed on the housing 10, for example, four air inlets 101, five air inlets 101 are disposed on the housing 10, and the air inlet directions of each air inlet 101 are different, so that air flow in the inner space and the outer space of the sterilizing and deodorizing device is disturbed, the deodorizing area of the sterilizing and deodorizing device is increased, and a good deodorizing effect is achieved.

According to the embodiment of the utility model, through the three air inlets 101 and the air outlet 102 on the shell 10, the sterilizing and deodorizing device can simultaneously intake air from the plurality of air inlets 101, so that the air intake area of the sterilizing and deodorizing device can be increased, the air intake quantity of the sterilizing and deodorizing device in unit time is increased, and the air intake area of the sterilizing and deodorizing device is increased, but the air quantity is not increased in the same proportion, so that the air flow rate of the air inlets 101 can be reduced, the time of air retention in the sterilizing and deodorizing device is prolonged, and the sterilizing and deodorizing device can be fully contacted with the sterilizing and deodorizing component 30, and the deodorizing efficiency is improved.

In addition, three air outlets 102 and an air inlet 101 can be further arranged on the shell 10, a ventilation air duct is formed in the shell 10 and is communicated with the air inlet 101 and each air outlet 102, and the air outlet area is increased to disturb the air flow in the inner space and the outer space of the sterilizing and deodorizing device, so that the air flow in the inner space and the outer space of the sterilizing and deodorizing device is disturbed, the deodorizing area of the sterilizing and deodorizing device is increased, and a good deodorizing effect is achieved.

The arrangement of the plurality of air outlets 102 may refer to the arrangement of the plurality of air inlets 101, which is not described herein.

Specifically, as shown in fig. 1 to 3, it can be understood that the casing 10 has a rectangular structure and has a top surface, a bottom surface and four side surfaces, when two air inlets 101 are provided on the casing 10, two air inlets 101 may be provided on two adjacent side surfaces on the casing 10, an air outlet 102 is provided on the top surface of the casing 10, which is equivalent to that the planes of the air inlets 101 and the air outlets 102 are mutually perpendicular, and the fan 20 is provided inside the casing 10 and is provided corresponding to the position of the air outlet 102.

When the fan 20 starts to work, the air in the space where the sterilizing and deodorizing device is located enters the sterilizing and deodorizing device from the two air inlets 101 respectively, and the air in different areas in the inner space and the outer space of the sterilizing and deodorizing device can be disturbed due to different air inlet directions of the two air inlets 101, so that the air entering the inside of the sterilizing and deodorizing device can be fully contacted with the sterilizing and deodorizing component 30 after being disturbed, or the air passes through the sterilizing and deodorizing component 30, and the deodorizing effect is better.

The structure of the housing 10 may be a rectangular structure, a prismatic structure, a truncated cone structure, or the like, for example, when four air inlets 101 are provided on the housing 10, the housing 10 may be a pentagonal prism, and the four air inlets 101 are respectively provided on four adjacent side surfaces of the housing 10.

It should be noted that, the air inlet 101 and the air outlet 102 are located on different planes, and the air inlet 101 and the air outlet 102 are prevented from being disposed opposite to each other. So as to prevent wind from entering from the air inlet 101 and then being directly discharged from the air outlet 102, thereby shortening the contact time with the sterilizing and deodorizing component 30 and affecting the deodorizing efficiency.

As shown in fig. 2 to 4, it can be understood that the sterilizing and deodorizing module 30 includes a first electrode 301 and a second electrode 302 disposed at a distance, the first electrode 301 is disposed near the air inlet 101, the second electrode 302 is disposed near the air outlet 102, and a strong electric field is formed between the first electrode 301 and the second electrode 302 after a high voltage is applied to the first electrode 301 or the second electrode 302, i.e., the strength of the electric field is as high as 30kv/cm, and under the effect of the strong electric field, the gas generates electric discharge and local ionization, and a large amount of oxygen, hydroxyl radicals, active factors and free radicals are generated during the ionization of the gas to purify the passing gas.

Specifically, when the fan 20 starts to work, after the first electrode 301 and the second electrode 302 are connected to the high-voltage power supply, a high-voltage electric field is formed between the first electrode 301 and the second electrode 302, and the gas in the space where the sterilizing and deodorizing device is located enters the sterilizing and deodorizing device from the plurality of air inlets 101 respectively, and is decomposed and oxidized by the high-voltage electric field to ionize macromolecules in the gas into small molecules, or ionize part of the gas into carbon dioxide and water, so that organic components and harmful substances in the gas are effectively eliminated, and the purposes of deodorizing and sterilizing are achieved.

As shown in fig. 2 to 4, it may be understood that, in order to make the deodorizing effect of the sterilizing and deodorizing device better, the sterilizing and deodorizing module 30 further includes a catalyst portion 303, where the catalyst portion 303 may be disposed on a side of the second electrode 302 near the air outlet 102, that is, along the air inlet direction, the first electrode 301, the second electrode 302, and the catalyst portion 303 are sequentially stacked, so as to form an ionization space near the air inlet 101, so that the air entering the sterilizing and deodorizing device from the air inlet 101 can be ionized first, and then the ionized air passes through the catalyst portion 303 and is better absorbed by the catalyst portion 303, so as to improve the deodorizing efficiency.

In addition, the catalyst portion 303 may be disposed between the first electrode 301 and the second electrode 302, so that a first ionization space is formed between the first electrode 301 and the catalyst portion 303, and a second ionization space is formed between the second electrode 302 and the catalyst portion 303, so that when the gas flows from each air inlet 101 to the air outlet 102 along the ventilation duct, the decomposition effect of macromolecules in the gas is better and the odor removing effect is better through ionization, catalysis and ionization.

The catalyst portion 303 may be an adsorption material for adsorption and deodorization such as a nano-ore crystal, activated carbon, bamboo charcoal bag, activated alumina, and honeycomb ceramics.

As shown in fig. 2 to 4, it can be understood that, in order to further improve the deodorizing effect of the sterilizing and deodorizing device, the catalyst portion 303 is a photocatalyst portion 303, and the photocatalyst portion 303 can easily decompose various harmful substances, perform antibacterial and sterilizing functions, and perform a function of reducing the amount of ozone. At least one side of the photocatalyst portion 303 is provided with a catalytic light source 304, and the catalytic light source 304 is adapted to irradiate the photocatalyst portion 303 and form a sterilizing substance, thereby achieving a deodorizing effect.

The catalyst carrier of the photocatalyst portion 303 may be any of honeycomb ceramics, foamed ceramics, and foamed nickel, and the photocatalyst carried by the photocatalyst portion 303 may be one or a mixture of several of oxides of manganese, iron, copper, titanium dioxide, and graphene.

The wavelength range of the catalytic light source 304 may be the visible wavelength range. The catalytic light source 304 may be an ultraviolet lamp, the wavelength of which may be 360nm-380nm and 260nm-280nm, and the wavelength of which may be 254nm or 180nm.

For example, when the catalyst carried by the photocatalyst portion 303 is titanium dioxide, the titanium dioxide is activated by light energy in the visible light wavelength range, and shows a catalytically active reaction, so that the decomposition efficiency of organic substances (microorganisms and malodorous components) is increased.

When the photocatalyst portion 303 is located between the first electrode 301 and the second electrode 302, a space of 2mm to 20mm is maintained between the photocatalyst portion 303 and any one of the first electrode 301 and the second electrode 302, so that a discharge space exists between the first electrode 301 and the photocatalyst portion 303, or a discharge space exists between the second electrode 302 and the photocatalyst portion 303, to achieve a good discharge effect.

That is, a first gap 305 is formed between at least one of the first electrode 301 and the second electrode 302 and the catalyst portion 303, and the size of the first gap 305 may be 2mm to 20mm, and the specific gap size may be selected according to actual use conditions.

When the first gap 305 exists between the photocatalyst portion 303 and the first electrode 301 and the second electrode 302, the ultraviolet lamp tube may be disposed on two sides of the photocatalyst portion 303, or may be disposed only on one side of the second electrode 302 close to the air outlet 102, so as to reduce the concentration of ozone product and improve the odor removing efficiency by photocatalytic decomposition of oxidative components generated by high-voltage ionization.

Since a high voltage electric field is generated between the first electrode 301 and the second electrode 302 and a discharge phenomenon is caused, a powerful plasma region is formed, free electrons passing through the plasma region are accelerated by the high voltage electric field and react with gas, and a large amount of OH radicals and ozone are generated. Therefore, the photocatalytic reaction is performed at a position near the air outlet 102 so that the generated ozone contacts the surface of the photocatalyst to perform the catalytic reaction, thereby reducing the ozone concentration.

When there is a first gap 305 between the photocatalyst portion 303 and the first electrode 301 and no gap between the photocatalyst portion 303 and the second electrode 302, the ultraviolet lamp may be disposed on a side of the photocatalyst portion 303 close to the air inlet 101 or on a side of the photocatalyst portion 303 close to the air outlet 102, so as to reduce the concentration of ozone products and improve the odor removal efficiency by using photocatalytic decomposition of oxidative components generated by high-voltage electricity. In this arrangement, the gas entering the sterilizing and deodorizing device is ionized into small molecules or excited states by high voltage, so that the gas is more easily catalyzed and degraded by the catalyst part 303, and the deodorizing effect is better.

When there is a first gap 305 between the photocatalyst portion 303 and the second electrode 302 and no gap between the first electrode 301, an ultraviolet lamp may be disposed on a side of the photocatalyst portion 303 near the air outlet 102, so as to reduce the concentration of ozone products and improve the odor removing efficiency by decomposing oxidative components generated by high-voltage electricity through photocatalysis.

As shown in fig. 1 and 2, it can be understood that a second gap 306 is formed between the first electrode 301 and the second electrode 302 and the inner wall of the housing 10, specifically, the second gap 306 exists before the bottom wall of the housing 10, that is, neither the first electrode 301 nor the second electrode 302 contacts the bottom wall of the housing 10, so as to avoid the first electrode 301 and the second electrode 302 discharging the housing 10 and causing accidents.

Equivalently, the first electrode 301 and the second electrode 302 are suspended in the housing 10, so that air insulation can be achieved between the first electrode 301 and the second electrode 302 and the housing 10.

Further, the second gap 306 is spaced more than 2mm apart to prevent the condensed water from sticking the electrode and the case 10, thereby causing the electrode to discharge to the case 10.

Of course, an insulating material, such as plastic, may be filled in the gap between the first electrode 301 and the second electrode 302 and the case 10, so as to insulate the first electrode 301 and the second electrode 302 from the case 10.

As shown in fig. 5 and fig. 6, it can be understood that, in order to increase the discharge areas of the first electrode 301 and the second electrode 302, the first electrode 301 and the second electrode 302 are hollow structures, that is, the first electrode 301 and the second electrode 302 are formed by criss-cross of a plurality of metal strips, so that the plurality of metal strips are arranged at intervals, and the discharge areas can be formed in the interval areas of the metal strips, so that not only the wind resistance can be reduced, but also the odor removing effect can be increased.

Furthermore, a tip structure may be provided on at least one of the first electrode 301 and the second electrode 302 to improve discharge efficiency and achieve a good ionization effect.

As shown in fig. 5, it can be understood that the first electrode 301 includes at least two connected first parallel segments, the second electrode 302 includes at least two connected second parallel segments, the first parallel segments and the second parallel segments are disposed corresponding to the position of the air inlet 101, and the first parallel segments and the second parallel segments are parallel to each other.

For example, when three air inlets 101 are provided on the housing 10, the first electrode 301 includes three first parallel sections, namely, a first parallel section a3011, a first parallel section b3012 and a first parallel section c3013, which are respectively denoted as a first parallel section a3011, a first parallel section b3012 and a first parallel section c3013, may be disposed independently of each other, or may be spliced together to form a monolithic structure.

In order to achieve a good discharge effect and to facilitate the mounting of the first electrode 301, the first electrode 301 may be integrally provided and cut to shape.

Correspondingly, the second electrode 302 includes three second parallel sections, namely a second parallel section a3021, a second parallel section b3022 and a second parallel section c3023, which are respectively denoted, and the second parallel section a3021, the second parallel section b3022 and the second parallel section c3023 may be disposed independently of each other or may be spliced with each other to form an integral structure.

Corresponding to the structure of the first electrode 301, in order to achieve a good discharge effect and facilitate the installation of the second electrode 302, the second electrode 302 may be integrally formed and cut into a shape.
