Detailed implementation manners
[0035] The following further describes in detail the implementation manners of the present utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.
[0036] In the description of the embodiments of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0037] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly defined and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.
[0038] In the embodiments of the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "below" and "beneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.
[0039] It can be understood that for the conventional air treatment components in the market, taking the odor removal and sterilization component as an example, the odor removal and sterilization component mainly consists of the following parts: a functional module 300 and a fan 200. The functional module 300 is usually used for odor removal and sterilization, and the fan 200 is used to generate air flow to help circulate air through the positions of both sterilization and odor removal. Since these sub-modules are separately distributed, during assembly, a corresponding housing structure or frame structure needs to be equipped to separately assemble the fan 200 and the functional module 300, so that the overall volume they occupy is relatively large, the space occupation is large, and the cost is high.
[0040]
[0041] For example: in refrigeration equipment products such as refrigerators, the above-mentioned odor-purifying and sterilization component block is usually placed in the air duct. Due to the thickness limit of the air duct, the thickness of the odor-purifying and sterilization component cannot exceed the thickness of the air duct. In the current design, since the fan 200 is installed on a frame structure or a shell structure, the overall thickness is increased. For example, according to the general thickness of 1.5mm design, due to the existence of the shell structure of the functional module 300 and the existence of the shell structure outside the fan 200, the thickness of the fan 200 part is increased by an additional 3mm. The existence of the above two shell structures may cause the thickness of the odor-purifying and sterilization component to exceed the plane of the air duct when used on ultra-thin air duct products, causing inconvenience in installation and design.
[0042] Combine the following Figures 1-6 The air handling device and refrigeration equipment of the embodiment of the utility model are described. It can be understood that in the embodiment of the utility model, the refrigeration equipment includes the above-mentioned air handling device, and the air handling device is installed on the refrigeration equipment. Taking a refrigerator as an example, the air handling device is installed in the air duct of the refrigerator. Of course, in some embodiments, the above-mentioned refrigeration equipment can also be a freezer, etc., which is not limited here.
[0043] Reference Figures 1 to 4 According to an embodiment of the utility model, an air treatment device includes a shell assembly 100 and a functional module 300. The shell assembly 100 is provided with an installation chamber 110, an air inlet 120 and an air outlet 130. The air inlet 120 and the air outlet 130 are respectively connected to the installation chamber 110. The installation chamber 110 is provided with a first installation area 111 and a second installation area 112. The air inlet 120 is located on one side of the first installation area 111, and the air outlet 130 is located on a side of the second installation area 112 away from the first installation area 111; wherein the first installation area 111 is used to install the fan 200, and the second installation area 112 is used to install the functional module 300.
[0044] According to the air handling device of the embodiment of the utility model, the fan 200 is installed in the first installation area 111 of the installation chamber 110 of the shell assembly 100, and the functional module 300 is installed in the second installation area 112. Therefore, the fan 200 and the functional module 300 are integrated with each other in the shell assembly 100 to form an integrated structure. The fan 200 and the functional module 300 of the utility model share the same shell assembly 100, which is beneficial to reducing the total occupied volume, the simple equipment makes the cost lower, and is conducive to popularization and application.
[0045] It should be noted that, in this embodiment, compared with the related art using two shells, the air treatment device in this embodiment reduces one shell structure, and the overall volume of the same shell assembly 100 is reduced by half, thereby reducing the number of redundant shell structures and making the overall thickness thinner.
[0046] Specifically, referring to Figures 1 to 4 , in the embodiment of the present utility model, the housing assembly 100 includes a first housing 170 and a second housing 180. The first housing 170 and the second housing 180 are detachably connected, and the first housing 170 and the second housing 180 cooperate to form an installation chamber 110, which can be conveniently separated and connected, making it more convenient for maintenance, cleaning or replacement of parts, without the need to disassemble the entire housing assembly 100. It can also simplify the manufacturing and assembly processes and improve production efficiency. It should be noted that the corresponding concave positions of the first housing 170 and the second housing 180 form the installation chamber 110 when they are connected. It should be noted that the detachable connection manner between the first housing 170 and the second housing 180 can be a snap connection manner, a bolt connection manner, etc., which is not limited herein.
[0047] It can be understood that referring to Figures 1 to 4 and Figure 6 , in the embodiment of the present utility model, the functional module 300 includes a deodorizing catalyst component 310 for decomposing odors and a plasma sterilization component 320 for high-pressure sterilization. Of course, in some embodiments, the above functional module 300 may also only include the deodorizing catalyst component 310 or the plasma sterilization component 320, or in some other embodiments, the above functional module 300 is a humidification module, a dehumidification module or an aromatic agent module, etc., which is not limited herein.
[0048] Specifically, in the embodiment of the present utility model, there is a spacing between the deodorizing catalyst component 310 and the plasma sterilization component 320. With the above design, the layout optimization can provide better odor decomposition and sterilization effects. By arranging the deodorizing catalyst component 310 and the plasma sterilization component 320 separately and maintaining a certain spacing, it is possible to avoid mutual interference or electric field interference between them, thereby improving the effects and performance of each module.
[0049] Specifically, referring to Figures 1 to 4 and Figure 6, in this embodiment, a controller 400 is provided in the second installation area 112. The plasma sterilization component 320 includes a high-voltage power supply 321 and an electrode unit 322. Both the electrode unit 322 and the high-voltage power supply 321 are electrically connected to the controller 400. With the above structure, there is an electrical connection between the high-voltage power supply 321, the electrode unit 322 and the controller 400 in the plasma sterilization component 320. Driven by the controller 400, the high-voltage power supply 321 generates plasma by exciting the electrode unit 322 through an electric field, thereby achieving an efficient sterilization effect and ensuring the stable operation of the module through control and adjustment. There is a connection and they work together to improve the effectiveness and reliability of the entire device in the refrigeration equipment. Of course, in some embodiments, the controller 400 can also be provided in the first installation area 111, or the controller 400 is arranged in both the first installation area 111 and the second installation area 112, which is not limited herein.
[0050] It should be noted that, in this embodiment, the blower 200 is electrically connected to the controller 400, and the stable operation of each module is ensured through the controller 400 and adjustment. There is a connection and they work together.
[0051] Specifically, referring to Figures 2 to 6 , in the embodiment of the present utility model, a partition baffle 1123 is provided in the second installation area 112 corresponding to the first housing 170. The second installation area 112 is divided into a first installation cavity 1121 and a second installation cavity 1122 by the partition baffle 1123; the controller 400 is provided in the first installation cavity 1121, the odor purification and catalyst component 310 is provided in the second installation cavity 1122, one end of the electrode unit 322 is electrically connected to the controller 400, and the other end penetrates through the partition baffle 1123 and extends into the second installation cavity 1122. By providing the partition baffle 1123 in the second installation area 112, it is divided into the first installation cavity 1121 and the second installation cavity 1122, and different components are placed in the corresponding cavities. The spatial separation helps to isolate different components and functions from each other, avoiding mutual interference or cross-influence. For example, in the functional module 300, by separately arranging the controller 400 and the odor purification and catalyst component 310 in different cavities, their independent operation can be ensured, improving the performance and effect of the overall system. The electrode unit 322 can be electrically connected to the controller 400 and transport charged particles into the second installation cavity 1122. In this way, the electrode unit 322 can release a high-voltage electric field in the second installation cavity 1122 to achieve a sterilization effect. At the same time, the presence of the partition baffle 1123 ensures the separation between the electrode unit 322 and other components, avoiding the interference of the electric field or interfering with other functions. It should also be noted that, in this embodiment, the above-mentioned high-voltage power supply 321 is also installed in the first installation cavity 1121.
[0052] Specifically, referring to Figures 2 to 4, in the embodiment of the present utility model, one side of the first installation area 111 is communicated with one side of the second installation cavity 1122, and the air outlet 130 is arranged on the other opposite side of the second installation cavity 1122. When the air flow flows between the air inlet 120 and the air outlet 130, it passes through part of the structures of the second installation cavity 1122, the odor removal catalyst component 310, and the electrode unit 322. It can be understood that the air inlet side of the odor removal catalyst component 310 corresponds to the air inlet 120, and the air outlet side of the odor removal catalyst component 310 corresponds to the air outlet 130.
[0053] With the above arrangement, through the through - setting of the first installation area 111 and the second installation cavity 1122, the air flow at the air inlet 120 can enter the second installation cavity 1122. Then, the air flow flows in the second installation cavity 1122 and passes through part of the structures of the odor removal catalyst component 310 and the electrode unit 322. When the air flow passes through the second installation cavity 1122, through the action of the odor removal catalyst component 310, odor - containing substances can be decomposed, improving the freshness of the air. The catalyst substance in the odor removal catalyst component 310 can accelerate the chemical reaction of the odor - containing substances and convert them into harmless substances or substances with a lighter smell. Therefore, when the air flow passes through the odor removal catalyst component 310, the odor - containing substances can be effectively treated and deodorized; the electrode unit 322 provides a high - voltage electric field and releases charged particles such as electrons and ions. These charged particles can destroy the cell structure and function of microorganisms, achieving a sterilization effect. Therefore, when the air flow passes through the electrode unit 322, the microorganisms will be killed by the action of the electric field. Finally, the air flow is discharged from the air outlet 130 of the second installation cavity 1122, thereby providing a fresher and more hygienic air environment.
[0054] Specifically, referring to Figures 2 to 4 , in the embodiment of the present utility model, a limiting structure 140 is provided in the second installation cavity 1122. The limiting structure 140 cooperates with the second installation cavity 1122 to define an installation space for installing the odor removal catalyst component 310. With the above structure, the installation space of the odor removal catalyst component 310 can be defined. The design and shape of the limiting structure 140 match the odor removal catalyst component 310, ensuring that the odor removal catalyst component 310 is installed in the correct position and preventing it from moving or falling off during use. It can ensure that the odor removal catalyst component 310 can effectively play its function, simplify the installation process, increase the stability of the odor removal catalyst component 310, and is convenient for maintenance.
[0055] Specifically, referring to Figures 2 to 4, in the embodiment of the present utility model, the limiting structure 140 includes a first limiting plate 141, a second limiting plate 142, a third limiting plate 143 and a fourth limiting plate 144. The first limiting plate 141 and the second limiting plate 142 are spaced on one side of the second installation cavity 1122, and the third limiting plate 143 and the fourth limiting plate 144 are spaced on the opposite side of the second installation cavity 1122. Among them, the first limiting plate 141, the second limiting plate 142, the third limiting plate 143 and the fourth limiting plate 144 cooperate with each other and enclose an installation space with the bottom wall of the second installation cavity 1122. Through the above settings, the first limiting plate 141, the second limiting plate 142, the third limiting plate 143 and the fourth limiting plate 144 cooperate with each other to form a space for installing the odor removal catalyst component 310, which can be firmly fixed in the installation space, further improving its stability in the installation space, enhancing its working effect and reliability, with a simple structure and being easy to manufacture.
[0056] It can be understood that, referring to Figures 2 to 4 , in the embodiment of the present utility model, a positioning structure 150 is provided in the first installation cavity 1121 of the second installation area 112. The positioning structure 150 is used to cooperate with the controller 400 to limit the relative position between the controller 400 and the first installation cavity 1121 of the second installation area 112, which can ensure the stable fixation and correct positioning of the controller 400, improve the stability and reliability of the device, and simplify the installation process.
[0057] Specifically, referring to Figures 2 to 4 , in the embodiment of the present utility model, the positioning structure 150 includes a first positioning portion 151 and a second positioning portion 152. The first positioning portion 151 and the second positioning portion 152 are respectively located on the opposite side surfaces of the inner wall of the first installation cavity 1121 of the second installation area 112. Among them, the first positioning portion 151 is a positioning groove, and the positioning groove is in an insertion fit with one end of the controller 400. The second positioning portion 152 is a supporting boss, and the supporting boss is in a butt joint fit with the opposite side surface of the control board of the controller 400. This can simplify the manufacturing process. Through appropriate processing and assembly, the positioning groove, the supporting boss and the inner wall of the first installation cavity 1121 are made to match each other, restricting the horizontal movement of the controller 400 in the direction towards the second installation cavity 1122, achieving stable connection and accurate positioning.
[0058] Of course, in some embodiments, the above positioning structure 150 can also be a positioning bolt to fix the controller 400 through the positioning bolt.
[0059] It can be understood that, referring to Figures 2 to 4 and Figure 6, in the embodiment of the present utility model, the controller 400 is provided with an insertion position. The electrode unit 322 includes a plurality of electrode pins 3221 arranged side by side and a first fixing seat 3222. The plurality of electrode pins 3221 are inserted into and electrically connected to the insertion position. The plurality of electrode pins 3221 are connected to the same first fixing seat 3222, and the first fixing seat 3222 abuts against the controller 400 to limit the relative movement of the electrode unit 322 relative to the controller 400. It can be understood that the control board of the controller 400 has an insertion position. When the first fixing seat 3222 is inserted into the insertion position, the first fixing seat 3222 abuts against the control board of the controller 400.
[0060] With the above arrangement, by using a plurality of electrode pins 3221 arranged side by side as the basic mesh electrodes, the plurality of electrode pins 3221 are installed in the insertion position by an insertion method, and the relative movement of the electrode unit 322 relative to the controller 400 is restricted by the first fixing seat 3222, fixing the relative positions of the electrode unit 322 and the controller 400. Therefore, by cooperating the insertion method with the first fixing seat 3222, the structure is simplified, the installation efficiency is high, and the manufacturing cost is relatively low.
[0061] Specifically, referring to Figure 6 , in this embodiment, the first fixing seat 3222 is sleeved on the outer walls of the plurality of electrode pins 3221, providing support and retention for the electrode pins 3221 to ensure that they are stably fixed in the correct positions.
[0062] Specifically, referring to Figure 6 , in this embodiment, the first fixing seat 3222 is a plastic part, with a simple structure, light weight, good insulation and corrosion resistance, and a relatively low manufacturing cost.
[0063] Specifically, referring to Figure 6 , in this embodiment, the first fixing seat 3222 and the plurality of electrode pins 3221 are of an integral structure, providing strength and stability. The integral structure eliminates the steps of separately installing and fixing the first fixing seat 3222 and the electrode pins 3221, simplifies the assembly process, can save time and labor, and reduces the possible errors in the assembly process, optimizes the electrical performance and reduces the number of components.
[0064] It can be understood that, referring to Figures 2 to 5In the embodiment of the utility model, the first shell 170 is provided with a first fixing structure 160, and the first fixing structure 160 is located in the first installation cavity 1121. The electrode unit 322 is provided with a second fixing structure 3223. The second fixing structure 3223 is engaged with the second fixing structure 3223 to limit the relative position of the electrode unit 322 and the shell assembly 100. During assembly, the electrode unit 322 and the shell assembly 100 are relatively fixed through the cooperation of the first fixing structure 160 and the second fixing structure 3223. The structure is simple, the operation is convenient and the positioning is reliable.
[0065] It should be noted that, refer to Figures 2 to 4 as well as Figure 6 In this embodiment, the partition baffle 1123 and the first shell 170 are an integrated structure, and the partition baffle 1123 is arranged around the first installation cavity 1121. The partition baffle 1123 is provided with a first channel 11231 communicating with the first installation cavity 1121 and the second installation cavity 1122. The other end of the electrode unit 322 is passed through the first channel 11231, and the second fixing structure 3223 can close the first channel 11231. When the circuit part of the controller 400 in the first installation cavity 1121 is glued, the first channel 11231 is closed by the second fixing structure 3223 according to the glue filling height, so as to prevent the glue from leaking from the first channel 11231, thereby improving the airtightness.
[0066] It is understandable that, referring to Figures 2 to 6 In the embodiment of the utility model, the first fixing structure 160 is a fixing platform, the fixing platform is provided with a fixing groove 161, a side wall of the fixing groove 161 is provided with a second channel, and the first channel 11231 is connected to the other side wall opposite to the fixing groove 161; the second fixing structure 3223 includes a second fixing seat, the second fixing seat is snap-fitted with the fixing groove 161, and the side wall area of the second fixing seat facing the first channel 11231 is larger than the cross-sectional area of the first channel 11231. With the above arrangement, a fixed and positioned connection is formed between the first fixing structure 160 and the second fixing structure 3223 through the snap-fitting of the fixing groove 161 and the second fixing seat. The fixing groove 161 of the fixing table provides a fixed position, and the second fixing seat is snap-fitted in the fixing groove 161 to ensure a firm connection between the first fixing structure 160 and the second fixing structure 3223, and to define their relative position. The side wall area of the second fixing seat is larger than the cross-sectional area of the first channel 11231, thereby limiting the movement of the second fixing seat into the first channel 11231 and facilitating the closure of the first channel 11231 for sealing and glue pouring.
[0067] It should be noted that, in some embodiments, the height of the second fixed seat is adapted to the height of the fixing groove 161, or, when the height of the second fixed seat is lower than the height of the fixing groove 161, the second fixing structure 3223 also includes a fixing plug, which is installed in the fixing groove 161, and the fixing plug cooperates with the second fixed seat to coordinately close the first channel 11231 and block the connection between the first installation cavity 1121 and the second installation cavity 1122; the cross-section of the second fixed seat is rectangular, and the shapes of the fixing groove 161 and the second fixed seat are adapted to limit the rotation of the second fixed seat relative to the fixing groove 161, thereby improving the stability of the assembly.
[0068] It is understandable that, referring to Figure 6 In the embodiment of the utility model, the two opposite side walls of the fixing groove 161 are respectively provided with guiding slopes 1611, and the guiding slopes 1611 are used to guide the second fixing structure 3223 to be inserted into the fixing groove 161. When the second fixing structure 3223 is inserted, the guiding slopes 1611 will guide it to move along the direction of the slopes so that it is aligned with the corresponding part in the fixing groove 161. Through the action of the guiding slopes 1611, the insertion process becomes simpler and more accurate.
[0069] It is understandable that, referring to Figure 6 In the embodiment of the utility model, the second fixing seat is a plastic part with a simple structure, light weight, good insulation and corrosion resistance, and low manufacturing cost.
[0070] Specifically, refer to Figure 6 In an embodiment of the utility model, the second fixing seat and the multiple electrode pins 3221 of the electrode unit 322 are an integrated structure, which provides strength and stability. The integrated structure eliminates the need to separately install and fix the second fixing seat and the electrode pins 3221, simplifies the assembly process, saves time and labor, reduces possible errors during the assembly process, optimizes electrical performance, and reduces the number of components.
[0071] It is understandable that, referring to Figure 3 , Figure 4 and Figure 6, in the embodiment of the present utility model, the electrode unit 322 further includes a third fixing seat 3224. The third fixing seat 3224 is connected to a plurality of electrode pins 3221, and the third fixing seat 3224 is used to keep a distance between the plurality of electrode pins 3221 and the odor-removing catalyst component 310. Among them, the first fixing seat 3222, the second fixing seat, and the third fixing seat 3224 are arranged in sequence along the length direction of the electrode pins 3221. With the above arrangement, by using the third fixing seat 3224 to keep a distance between the plurality of electrode pins 3221 and the odor-removing catalyst component 310, unnecessary contact and mutual interference can be reduced, thereby reducing the risk of air arcing that may be caused. And by arranging the first fixing seat 3222, the second fixing seat, and the third fixing seat 3224 in sequence along the length direction of the electrode pins 3221, the electrode pins 3221 can be effectively supported to keep them straight and balanced throughout the length, which helps to evenly distribute the electric field, improve the sterilization efficiency and effect.
[0072] Similarly, it should be noted that with reference to Figure 6 , in this embodiment, the third fixing seat 3224 is a plastic part, which has a simple structure, is lightweight, has good insulation and corrosion resistance, and has a low manufacturing cost. The third fixing seat 3224 and the plurality of electrode pins 3221 of the electrode unit 322 are of an integral structure, which provides strength and stability. The integral structure eliminates the steps of separately installing and fixing the third fixing seat 3224 and the electrode pins 3221, simplifies the assembly process, can save time and labor, reduces possible errors in the assembly process, optimizes the electrical performance, and reduces the number of components.
[0073] It should be noted that with reference to Figures 2 to 4 and Figure 6 , in the embodiment of the present utility model, there are two groups of electrode units 322. The two groups of electrode units 322 are arranged at intervals and are electrically connected to the controller 400. Among them, one group of electrode units 322 is located on the air inlet side of the odor-removing catalyst component 310, and the other group of electrode units 322 is located on the air outlet side of the odor-removing catalyst component 310. Through the above arrangement, two-way treatment of air can be achieved. The electrode unit 322 on the air inlet side can be used to remove pollutants or odors in the air, while the electrode unit 322 on the air outlet side can further purify the air to ensure the freshness and cleanliness of the outlet air.
[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
