[0012] In some embodiments, the air duct module is disposed within the receiving cavity, dividing the receiving cavity into a first chamber and a second chamber. The air duct module has two return air inlets, which are respectively connected to the first chamber and the second chamber. The odor removal module is disposed between the two return air inlets.

[0013] In some embodiments, the air duct module is disposed within the receiving cavity, dividing the receiving cavity into a first chamber and a second chamber. The air outlet duct includes a first air outlet duct and a second air outlet duct. Along the thickness direction of the housing, the odor-removing air duct, the first air outlet duct, and the second air outlet duct are arranged at intervals.

[0014] In some embodiments, the odor-removing air duct is disposed near the door of the refrigeration equipment, the second air outlet duct is disposed near the rear wall of the cabinet, and the first air outlet duct is disposed between the odor-removing air duct and the second air outlet duct.

[0015] In some embodiments, the first air outlet duct includes an interconnected arc segment and a straight segment. Along the height direction of the housing, the arc segment is disposed below the straight segment, and the odor-removing module is at least partially disposed inside the arc segment.

[0016] In some embodiments, the air duct module includes a first air duct unit and a second air duct unit, wherein the first air duct unit is installed in the housing and the second air duct unit is detachably connected to the first air duct unit;

[0017] The odor-removing air duct includes a first odor-removing air duct disposed within the first air duct unit and a second odor-removing air duct disposed within the second air duct unit, and the odor-removing module is installed in the second odor-removing air duct;

[0018] The air outlet duct includes a first section of the air outlet duct disposed in the first air outlet duct unit and a second section of the air outlet duct disposed in the second air outlet duct unit;

[0019] The return air vent is located in the first air duct unit and / or the second air duct unit.

[0020] In some embodiments, the second air duct unit has a first transition surface, the first air duct unit has a first air outlet surface, and the first transition surface contacts the first air outlet surface; the second air duct unit has a second transition surface, and the second air duct module of the air duct module has a second air supply surface, and the second transition surface contacts the second air supply surface.

[0021] In some embodiments, the first transition surface and the first air outlet surface are inclined.

[0022] In some embodiments, the second air duct unit includes:

[0023] The second housing assembly is detachably connected to the first air duct unit;

[0024] The second filling component is disposed inside the second outer shell component. The second outer shell component, the second filling component, and the first air duct unit together form the second odor-removing air duct. The second filling component has a second section of the air outlet duct. The second outer shell component has a return air vent. The second filling component and the second outer shell component together form a limiting groove. The odor-removing module is disposed in the limiting groove.

[0025] In some embodiments, the thickness of the door of the refrigeration equipment is 25mm to 40mm, and the total thickness of the cabinet and the door is 450mm to 600mm.

[0026] The present invention has at least the following beneficial effects:

[0027] The refrigeration equipment includes a housing, an air duct module, and an odor removal module. The housing has a receiving cavity. The air duct module is located inside the housing. The air duct module has an air outlet duct and an odor removal duct arranged at intervals. Both the air outlet duct and the odor removal duct are used to supply air to the receiving cavity. The air duct module also has a return air vent for connecting with the refrigeration unit. The odor removal duct is connected to the return air vent. The odor removal module is installed in the odor removal duct.

[0028] If strong-smelling foods, such as dried pickles or hot pot broth, are stored in the refrigerator, their odors can transfer to other items, leading to a poor user experience. The refrigeration unit features a deodorizing air duct in its airflow module. Air entering from the return air vent is transported through this duct before being exhausted into the storage cavity. The deodorizing module, located within this duct, draws air from the storage cavity through the return air vent, where it undergoes odor removal processing by its deodorizing components before being exhausted back into the storage cavity. This deodorizing module effectively removes odors from the air within the storage cavity, reducing the likelihood of cross-contamination of odors between foods and resulting in fresher air and a better user experience.

[0029] In addition, the refrigeration equipment has both the odor removal duct and the air outlet duct inside the duct module, and the odor removal module is set inside the odor removal duct, that is, integrated into the duct module. This effectively utilizes the internal space of the duct module and reduces the space occupied by the odor removal module, odor removal duct and air outlet duct on the rest of the refrigeration equipment. This will help reduce the size of the refrigeration equipment and enable the refrigeration equipment to develop in the direction of smaller size and ultra-thin. Attached Figure Description

[0050] Currently, most mainstream refrigeration equipment on the market has the problem of large size. Refrigerators, freezers and other refrigeration equipment often occupy a large space in the kitchen or home environment. This is undoubtedly a heavy burden for families with limited living space, especially urban apartments and small apartments. The large size of refrigerators also limits the flexibility of kitchen layout and affects the harmony and aesthetics of the overall home design.

[0051] Therefore, the large size of mainstream refrigeration equipment on the market presents consumers with various challenges and inconveniences.

[0052] This application provides a refrigeration device that can at least partially solve the technical problem of large external dimensions of refrigeration devices.

[0053] The refrigeration equipment can be a refrigerator, freezer, etc., and is not limited in this application. For ease of description, the following description uses a refrigerator as an example of the refrigeration equipment.

[0054] The refrigeration equipment is roughly rectangular. For ease of description, we define the height direction (Z), width direction (X), and thickness direction (Y). In the operating state of the refrigeration equipment, the vertical direction is the height direction (Z), and the projection of the refrigeration equipment in the vertical direction is a rectangle. The direction of the longer side is the width direction (X), and the direction of the shorter side is the thickness direction (Y).

[0055] Similarly, for ease of description, six directions are defined: up, down, left, right, front, and back. In the height direction Z, the direction closer to the top surface is up, and the direction further from the top surface is down. In the width direction X, the two directions are left and right. The refrigeration equipment chamber has an opening for loading and unloading, and a door is located at the opening. In the thickness direction Y, the direction closer to the door is front, and the direction further from the door is back.

[0056] This application is described below with reference to the accompanying drawings and specific embodiments:

[0057] As shown in Figures 1 to 7, the refrigeration equipment 1000 includes a housing 100, an air duct module 200, and an odor removal module 300. The housing 100 has a receiving cavity 100a. The air duct module 200 is disposed inside the housing 100. The air duct module 200 has an air outlet duct 200d and an odor removal duct 200a arranged at intervals. Both the air outlet duct 200d and the odor removal duct 200a are used to supply air to the receiving cavity 100a. The air duct module 200 also has a return air port 200e for communicating with the refrigeration unit 400. The odor removal duct 200a is connected to the return air port 200e. The odor removal module 300 is installed in the odor removal duct 200a.

[0058] The receiving cavity 100a can be used to store food, ice packs, flowers, and other items that need to be refrigerated. The air duct module 200 is located inside the cabinet 100, either inside or outside the receiving cavity 100a, for example, between the rear wall of the refrigerator and the inner liner; this application does not limit the location of the air duct module.

[0059] The air duct module 200 is provided with an air outlet duct 200d and an odor-removing duct 200a that are connected to the receiving cavity 100a. Both the air outlet duct 200d and the odor-removing duct 200a are used to supply air to the receiving cavity 100a. Specifically, the air outlet duct 200d is used to supply cool air at a lower temperature to the receiving cavity 100a, and the odor-removing duct 200a is used to supply air that has undergone odor removal treatment to the receiving cavity 100a.

[0060] The return air vent 200e is connected not only to the refrigeration unit 400 of the refrigeration equipment 1000, but also to the odor-removing air duct 200a. Both the refrigeration unit 400 and the odor-removing module 300 receive air through the return air vent 200e. After the air in the receiving cavity 100a flows back from the return air vent 200e, part of it enters the odor-removing air duct 200a, is processed by the odor-removing module 300, and then is transmitted to the receiving cavity 100a through the odor-removing air duct 200a. The other part enters the refrigeration unit 400, is cooled, and then is also transmitted to the receiving cavity 100a.

[0061] If strong-smelling foods, such as dried pickles or hot pot broth, are stored in the refrigerator, their odors can transfer to other items, leading to a poor user experience. The refrigeration unit 1000 incorporates a deodorizing air duct 200a in its air duct module 200. Air entering from the return air vent 200e is transported through the deodorizing air duct 200a and then exhausted into the receiving cavity 100a. The deodorizing module 300, located within the deodorizing air duct 200a, draws air from the receiving cavity 100a through the return air vent 200e. This air then undergoes deodorization treatment by its deodorizing components before being exhausted back into the receiving cavity 100a through the deodorizing air duct 200a. The deodorizing module 300 effectively removes odors from the air in the receiving cavity 100a, reducing the likelihood of cross-contamination of odors between foods and ensuring a fresher air environment, thus providing a better user experience.

[0062] In addition, the refrigeration equipment 1000 has both the odor-removing air duct 200a and the air outlet air duct 200d located within the air duct module 200, and the odor-removing module 300 is located within the odor-removing air duct 200a, that is, integrated within the air duct module 200. This effectively utilizes the internal space of the air duct module 200 and reduces the space occupied by the odor-removing module 300, the odor-removing air duct 200a, and the air outlet air duct 200d in the remaining space of the refrigeration equipment 1000. This will help reduce the external size of the refrigeration equipment 1000, enabling the refrigeration equipment 1000 to develop in the direction of smaller size and ultra-thin design.

[0063] The structure and principle of the odor-eliminating module 300 are diverse and known to those skilled in the art, and will not be elaborated here.

[0064] In some embodiments, the odor removal module 300 is disposed on the side of the odor removal air duct 200a near the return air vent 200e. Disposing the odor removal module 300 near the return air vent 200e brings it closer to the vent, helping to ensure the suction efficiency of the odor removal module 300.

[0065] In some embodiments, the return air vent 200e is located at the bottom of the receiving cavity 100a. The location of the return air vent 200e at the bottom of the receiving cavity 100a allows the odor-removing module 300 and the refrigeration unit 400 to draw air from the bottom of the receiving cavity 100a. This design promotes a more uniform and comprehensive circulation of air inside the refrigerator, helping to reduce dead zones and improve the overall air purification and cooling effect inside the refrigerator.

[0066] In some embodiments, the air duct module 200 is disposed within the receiving cavity 100a, dividing the receiving cavity 100a into a first chamber 100b and a second chamber 100c. The air duct module 200 has two return air inlets 200e, which are respectively connected to the first chamber 100b and the second chamber 100c. The odor removal module 300 is disposed between the two return air inlets 200e.

[0067] The air duct module 200 is disposed within the receiving cavity 100a, dividing the receiving cavity 100a into a first chamber 100b and a second chamber 100c. This design allows the air duct module 200 to not only support the odor-eliminating module 300, provide odor-eliminating air duct 200a to supply air to the receiving cavity 100a, and provide air outlet duct 200d to supply air to the receiving cavity 100a, but also to divide the receiving cavity 100a. This design, with the air duct module 200 located within the receiving cavity 100a, does not increase the thickness of the refrigerator, contributing to a thinner refrigerator suitable for more installation environments. Furthermore, this design eliminates the need for a separate divider for the receiving cavity 100a; the air duct module 200 integrates this function, resulting in higher integration of the refrigerator, reducing the number of parts, saving manufacturing costs, and contributing to a smaller overall size.

[0068] In these embodiments, the air duct module 200 has two return air inlets 200e, which are respectively connected to the first chamber 100b and the second chamber 100c. That is, one return air inlet 200e is connected to the first chamber 100b, and the other is connected to the second chamber 100c. This allows the odor-removing module 300 to simultaneously deodorize both chambers 100b and 100c, reducing odors in both chambers. This also allows the refrigeration unit 400 to simultaneously draw in air from both chambers 100b and 100c and cool it down. The odor-removing module 300 is positioned between the two return air inlets 200e, bringing it closer to the inlets and helping to ensure its air intake efficiency.

[0069] In some embodiments, the air duct module 200 is disposed in the receiving cavity 100a, dividing the receiving cavity 100a into a first chamber 100b and a second chamber 100c. The air outlet duct 200d includes a first air outlet duct 200d1 and a second air outlet duct 200d2. Along the thickness direction of the housing 100, the odor-removing air duct 200a, the first air outlet duct 200d1, and the second air outlet duct 200d2 are arranged at intervals.

[0070] The first air outlet duct 200d1 can be connected to the first chamber 100b and the second chamber 100c, or simultaneously to both chambers 100b and 100c; the second air outlet duct 200d2 can be connected to the first chamber 100b and the second chamber 100c, or simultaneously to both chambers 100b and 100c. Along the thickness direction of the housing 100, the odor-eliminating duct 200a, the first air outlet duct 200d1, and the second air outlet duct 200d2 are spaced apart to fully utilize the space of the duct module 200 along the thickness direction of the housing 100. This helps to reduce the size of the duct module 200 along the width direction of the housing 100, increasing the volume of the receiving cavity 100a, making the receiving cavity 100a larger and able to hold more items. It should be noted that both the first air outlet duct 200d1 and the second air outlet duct 200d2 are used to supply air to the receiving cavity 100a. In some embodiments, the first air outlet duct 200d1 is connected to the first chamber 100b, and the second air outlet duct 200d2 is connected to the second chamber 100c.

[0071] In some embodiments, the odor-removing air duct 200a is disposed near the door 500 of the refrigeration equipment 1000, the second air outlet duct 200d2 is disposed near the rear wall of the housing 100, and the first air outlet duct 200d1 is disposed between the odor-removing air duct 200a and the second air outlet duct 200d2.

[0072] In other words, along the thickness direction of the cabinet 100, the odor-removing air duct 200a, the first air outlet duct 200d1, and the second air outlet duct 200d2 are arranged sequentially, with the odor-removing air duct 200a located on the side near the refrigerator door 500 and the second air outlet duct 200d2 located on the side near the rear wall of the refrigerator.

[0073] In some implementations, the first air outlet duct 200d1 includes an interconnected arc segment 200d4 and a straight segment 200d3. Along the height direction of the housing 100, the arc segment 200d4 is located below the straight segment 200d3, and the odor removal module 300 is at least partially located inside the arc segment 200d4.

[0074] The straight segment 200d3 of the first air outlet duct 200d1 extends along the height direction of the cabinet 100, and the curved segment 200d4 is arc-shaped. The odor removal module 300 is located inside the curved segment 200d4. By setting the curved segment 200d4 to avoid the odor removal module 300, this design facilitates the installation of the odor removal module 300 and also helps to reduce the size occupied by the first air outlet duct 200d1, the second air outlet duct 200d2, and the odor removal duct 200a in the thickness direction of the cabinet 100. This reduces the size of the duct module 200 in the thickness direction of the cabinet 100, allowing the refrigerator to be designed to be thinner and its overall dimensions to be smaller.

[0075] In some embodiments, the air duct module 200 includes a first air duct unit 211 and a second air duct unit 214. The first air duct unit 211 is installed in the housing 100, and the second air duct unit 214 is detachably connected to the first air duct unit 211. The odor-removing air duct 200a includes a first odor-removing air duct 200a1 disposed in the first air duct unit 211 and a second odor-removing air duct 200a2 disposed in the second air duct unit 214. The odor-removing module 300 is installed in the second odor-removing air duct 200a2. The air outlet duct 200d includes a first section 200d5 disposed in the first air duct unit 211 and a second section 200d6 disposed in the second air duct unit 214. The return air vent 200e is opened in the first air duct unit 211 and / or the second air duct unit 214.

[0076] The first air duct unit 211 is fixedly installed on the housing 100, and the second air duct unit 214 is detachably connected to the first air duct unit 211. Therefore, the second air duct unit 214 can be removed from the first air duct unit 211. The odor-removing module 300 is installed on the second air duct unit 214, so the odor-removing module 300 can be removed together with the second air duct unit 214. With this design, the odor-removing module 300 can be removed from the first air duct unit 211 along with the second air duct unit 214, which facilitates the maintenance of the odor-removing module 300 and improves the efficiency of maintenance. The return air vent 200e can be opened on the first air duct unit 211, the second air duct unit 214, or both the first air duct unit 211 and the second air duct unit 214; this application does not limit the scope. It should be noted that both the first air outlet duct 200d1 and the second air outlet duct 200d2 include a first air outlet duct segment 200d5 disposed within the first air outlet unit 211 and a second air outlet duct segment 200d6 disposed within the second air outlet unit 214. In some embodiments, the first air outlet duct segment 200d5 of the first air outlet duct 200d1 is a straight segment 200d3, and the second air outlet duct segment 200d6 of the first air outlet duct 200d1 is an arc segment 200d4.

[0077] As shown in Figure 8, in some embodiments, the air duct module 200 includes a first air duct module 210, a second air duct module 220, and a third air duct module 230 arranged along the height direction of the housing 100. The first air duct module 210 is located above the third air duct module 230, and the second air duct module 220 is located between the first air duct module 210 and the third air duct module 230, and is connected to the first air duct module 210 and the third air duct module 230. In these embodiments, the first air duct module 210 includes a first air duct unit 211 and a second air duct unit 214, the second air duct module 220 has a transition air duct 220b, and the third air duct module 230 has a supply air duct 230a. The transition air duct 220b is connected to the supply air duct 230a and the outlet air duct 200d. A cooling unit 400 is installed in the third air duct module 230. The cooling unit 400 includes an evaporator 410, a fan 420, etc., which are components that cool and circulate the air. Under the action of the fan 420, the air in the receiving cavity 100a enters the supply air duct 230a of the third air duct module 230 from the return air port 200e, and is cooled by the evaporator 410, etc. Then it enters the transition air duct 220b and the outlet air duct 200d, and finally is discharged into the receiving cavity 100a, thereby cooling the receiving cavity 100a.

[0078] In some embodiments, a damper is provided inside the second air duct module 220. The damper is used to adjust the opening of the transition air duct 220b, thereby adjusting the airflow size. In these embodiments, the first air duct unit 211 is located on the second air duct unit 214, and the second air duct unit 214 is located on the second air duct module 220 and connected to the second air duct module 220. With this design, when the second air duct unit 214 is removed from the first air duct unit 211, the second air duct module 220 is exposed, which facilitates the maintenance of components such as dampers inside the second air duct.

[0079] In some embodiments, the second air duct unit 214 has a first transition surface 214a, the first air duct unit 211 has a first air outlet surface 211a, and the first transition surface 214a is in contact with the first air outlet surface 211a; the second air duct unit 214 has a second transition surface 214b, and the second air duct module 220 of the air duct module 200 has a second air supply surface 220a, and the second transition surface 214b is in contact with the second air supply surface 220a, as shown in Figure 4.

[0080] The first transition surface 214a of the second air duct unit 214 contacts the first air outlet surface 211a of the first air duct unit 211, so that the second section 200d6 of the air outlet duct in the second air duct unit 214 is connected to the first section 200d5 of the air outlet duct in the first air duct unit 211. The second transition surface 214b of the second air duct unit 214 contacts the second air supply surface 220a of the second air duct module 220, so that the second section 200d6 of the air outlet duct is connected to the transition duct 220b. With this design, the second air duct unit 214 and the first air duct unit 211 are in surface-to-surface contact, which helps to ensure that the second section 200d6 of the air outlet duct is in sealed connection with the first section 200d5 of the air outlet duct in the first air duct unit 211, and the second air duct unit 214 and the second air duct module 220 are in surface-to-surface contact, which helps to ensure that the second section 200d6 of the air outlet duct is in sealed connection with the transition duct 220b. To improve sealing performance, sealing gaskets, sealants, etc. can be provided on the first transition surface 214a, the first air outlet surface 211a, the second air supply surface 220a, and the second transition surface 214b.

[0081] In some embodiments, the second air duct unit 214 is connected to the first air duct unit 211 by bolts.

[0082] In some embodiments, the first transition surface 214a and the first air outlet surface 211a are arranged at an angle.

[0083] That is, the first transition surface 214a and the first air outlet surface 211a form an angle with the horizontal plane. This means that the inclination angles of the first transition surface 214a and the first air outlet surface 211a are the same. Due to the inclined surface fit between the first transition surface 214a and the first air outlet surface 211a, they have a self-positioning function when in contact, which allows for more precise positioning of the transition duct 220b and the air outlet duct 200d.

[0084] In some embodiments, the second air supply surface 220a and the second transition surface 214b are arranged horizontally.

[0085] As shown in Figures 9 to 16, in some embodiments, the second air duct unit 214 includes a second outer shell assembly 215 and a second filling assembly 216. The second outer shell assembly 215 is detachably connected to the first air duct unit 211. The second filling assembly 216 is disposed inside the second outer shell assembly 215. The second filling assembly 216 has a second odor-removing air duct 200a2 and a second section of the air outlet duct 200d6. The second outer shell assembly 215 has a return air vent 200e. The second filling assembly 216 and the second outer shell assembly 215 together form a limiting groove 214c. The odor-removing module 300 is disposed inside the limiting groove 214c.

[0086] The second filling component 216 is disposed within the second outer shell component 215. The second filling component 2162 and the second outer shell component 215 together form a limiting groove 214c for installing the odor-eliminating module 300. The odor-eliminating module 300 is limited within the limiting groove 214c. With this design, when the second air duct unit 214 is disassembled from the first air duct unit 211, the second filling component 216 and the second outer shell component 215 can be separated, and the odor-eliminating module 300 located between the second filling component 216 and the second outer shell component 215 can be removed, facilitating the maintenance of the odor-eliminating module 300. It should be noted that the second outer shell component 215 and the second filling component 216 can be connected together, such as by snap-fit ​​or adhesive bonding, or they can be disconnected. When the second filling component 216 is not connected to the second outer shell component 215, the second filling component 216 can be located within the second outer shell component 215 and limited by the second outer shell component 215.

[0087] In some embodiments, along the width direction of the housing 100, the second outer shell assembly 215 and the second filling assembly 216 are located at both ends of the odor-eliminating module 300, and the odor-eliminating module 300 is clamped by the second outer shell assembly 215 and the second filling assembly 216 213.

[0088] Some implementations have two types. The second housing assembly 215 includes a first housing 2151 and a second housing 2152 connected together. The second filling assembly 216 is disposed between the first housing 2151 and the second housing 2152. The first housing 2151 is detachably connected to the first air duct unit 211. The second housing 2152 and the second filling assembly 216 form a limiting groove 214c.

[0089] The first outer shell 2151 and the second outer shell 2152 are fixedly connected together. The second filling component 216 is disposed between the first outer shell 2151 and the second outer shell 2152. The first outer shell 2151 and the second outer shell 2152 protect the second filling component 216 and prevent it from being damaged by external impacts. The first outer shell 2151 is detachably connected to the first air duct unit 211 and can be removed from the first air duct unit 211. The second filling component 216 is located inside the first outer shell 2151 and the second outer shell 2152, and the first outer shell 2151 and the second outer shell 2152 are connected. Therefore, the first outer shell 2151, the second outer shell 2152, and the second filling component 216 as a whole can be removed from the first air duct unit 211. In these embodiments, the second outer shell 2152 and the second filling component 216 together form a limiting groove 214c of the limiting odor-eliminating module 300.

[0090] In some embodiments, the first outer shell 2151 and the second outer shell 2152 are arranged opposite to each other along the width direction of the housing 100, and the first outer shell 2151 and the second outer shell 2152 together form an installation chamber, and the second filling component 216 is confined in the installation chamber. When the first outer shell 2151 and the second outer shell 2152 are connected together, the second filling component 216 cannot be removed from the installation chamber.

[0091] The first outer shell 2151 and the second outer shell 2152 can be connected by means of snap-fit, bolt connection, screw connection, etc., which are not limited in this application.

[0092] In some embodiments, the second filling component 216 includes a first filling element 2161 and a second filling element 2162, both of which are disposed between the first housing 2151 and the second housing 2152. The second filling element 2162 is disposed between the first filling element 2161 and the second housing 2152, and the second filling element 2162 is shorter than the first filling element 2161. The first filling element 2161 and the second housing 2152 form a limiting groove 214c.

[0093] The second filler 2162 is located between the first filler 2161 and the second outer shell 2152. The second filler 2162 is shorter than the first filler 2161, so that the first filler 2161 and the second outer shell 2152 can be closed together to form a limiting groove 214c. Specifically, the portion of the first filler 2161 extending beyond the second filler 2162 and the second outer shell 2152 together form the limiting groove 214c. With this design, the odor-eliminating module 300 can be removed from the first filler 2161 after the first outer shell 2151 and the second outer shell 2152 are disassembled and separated, without the need to separate the first filler 2161 and the second filler 2162 again. This makes the disassembly of the odor-eliminating module 300 more convenient and helps to improve maintenance efficiency.

[0094] In some embodiments, corresponding protrusions and grooves are provided on the first filler and the second filler 2162, and the first filler 2161 and the second filler 2162 are positioned and fitted together by inserting the protrusions into the grooves.

[0095] As shown in Figure 16, in some embodiments, the inner wall of the limiting groove 214c is provided with a first limiting part 2161a, a second limiting part 2161b and a third limiting part 2161c at intervals, and the first limiting part 2161a, the second limiting part 2161b and the third limiting part 2161c are all in contact with the outer surface of the odor removal module 300.

[0096] The first limiting part 2161a, the second limiting part 2161b and the third limiting part 2161c all contact the outer surface of the odor-removing module 300 to limit the odor-removing module 300, ensure the accuracy of the position of the odor-removing module 300 and reduce the shaking of the odor-removing module 300.

[0097] In some embodiments, along the height direction of the housing 100, the first limiting part 2161a and the second limiting part 2161b are respectively located at both ends of the odor-removing module 300, and along the thickness direction of the housing 100, the second limiting part 2161b and the third limiting part 2161c are respectively located at both ends of the odor-removing module 300.

[0098] Along the height direction of the housing 100, the first limiting part 2161a and the second limiting part 2161b are located above the odor-removing module 300 and below the odor-removing module 300, respectively. Along the thickness direction of the housing 100, the second limiting part 2161b and the third limiting part 2161c are located on both sides of the odor-removing module 300, and the odor-removing module 300 is in contact with the first limiting part 2161a, the second limiting part 2161b and the third limiting part 2161c. In this way, along the height direction of the cabinet 100, the odor-removing module 300 is limited by the first limiting part 2161a and the second limiting part 2161b, and the odor-removing module 300 will not move along the height direction of the cabinet 100. Along the thickness direction of the cabinet 100, the odor-removing module 300 is limited by the second limiting part 2161b and the third limiting part 2161c, and the odor-removing module 300 will not move along the thickness direction of the cabinet 100. Along the width direction of the cabinet 100, the odor-removing module 300... Limited by the second outer shell assembly 215 and the second filling assembly 216, the odor-removing module 300 will not move along the width direction of the housing 100. Under the combined action of the first limiting part 2161a, the second limiting part 2161b, the third limiting part 2161c, the second outer shell assembly 215 and the second filling assembly 216, the odor-removing module 300 is fixed in the limiting groove 214c, which ensures the accuracy of the position of the odor-removing module 300 and helps to ensure the stable operation of the odor-removing module 300.

[0099] In some embodiments, the first air duct unit 211 includes a first housing assembly 212 and a first filling assembly 213 installed on the first housing assembly 212.

[0100] In some embodiments, the first outer casing assembly 212 includes a third outer casing 2121 and a fourth outer casing 2122 that are spaced apart and fixedly connected along the width direction of the housing 100. The first filling assembly 213 includes a third filling element 2131 and a fourth filling element 2132 that are arranged side by side along the width direction of the housing 100. The third filling element 2131 and the fourth filling element 2132 enclose a first odor-removing air duct 200a1 and a first odor-removing air duct 200a1. The third filling element 2131 and the fourth filling element 2132 are disposed between the third outer casing 2121 and the fourth outer casing 2122 and are clamped by the third outer casing 2121 and the fourth outer casing 2122. The first outer casing 2151 is detachably connected to the third outer casing 2121. The third filling element 2131 and the fourth filling element 2132 are both located between the third outer casing 2121 and the fourth outer casing 2122. The third outer casing 2121 and the fourth outer casing 2122 protect the second filling assembly 216.

[0101] In some embodiments, along the height direction of the housing 100, the fourth outer shell 2122 is longer than the third outer shell 2121, the lower end of the fourth outer shell 2122 extends out of the third outer shell 2121, and the second outer shell 2152 is located between the first filler 2161 and the fourth outer shell 2122. That is, the first filler 2161, the second filler 2162 and the second outer shell 2152 are all located between the first outer shell 2151 and the fourth outer shell 2122.
