[0045] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-10 A refrigerator 100 according to an embodiment of the first aspect of the present invention is described.

[0046] like Figure 1 and Figure 2 As shown, the refrigerator 100 according to the embodiment of the first aspect of the present invention includes a cabinet body 1, a door body 2, at least one shelf 3 and at least one fixed structure 4.

[0047] Specifically, the cabinet body 1 is formed with an opening 11, and the door body 2 is arranged at the opening 11 for opening and closing the opening 11. The door body 2 and the cabinet body 1 jointly define a accommodating cavity 12, and the shelf 3 is arranged in the accommodating cavity 12. The fixing structure 4 is detachably arranged between the shelf 3 and the cabinet body 1 for fixing the shelf 3 during the transportation of the refrigerator 100.

[0048] The refrigerator 100 further includes a catalyst box 5, which is disposed on the fixed structure 4. The interior of the catalyst box 5 is in communication with the accommodating cavity 12. At least one catalyst member 51 is disposed inside the catalyst box 5.

[0049] For example, in Figure 1 and Figure 2 In the example, the refrigerator 100 can achieve a sealed design of the accommodating cavity 12 through the cooperation of the cabinet body 1 and the door body 2, avoiding interference with the heat exchange with the external environment on the temperature regulation in the accommodating cavity 12, which is conducive to regulating the temperature of objects in the accommodating cavity 12.

[0050] The shelves 3 can divide the storage cavity 12 into multiple spaces, which is convenient for placing different items (such as food, drinks or facial masks) in different spaces, thereby improving the flexibility of the refrigerator 100. It also avoids multiple items being placed in the same storage cavity 12 and stacked, thereby avoiding damage due to squeezing, and is also convenient for taking and placing. It should be noted that there can be multiple shelves 3, and the multiple shelves 3 are spaced apart along the length direction of the refrigerator 100, and can be equally spaced or unequally spaced. In the description of the present utility model, the meaning of "multiple" is two or more. For example, Figure 1 As shown, there are three shelves 3, which divide the accommodating cavity 12 into four spaces, making it convenient to place a variety of different items.

[0051] The fixing structure 4 secures the shelves 3, preventing them from shaking and being damaged during transport. This improves the stability of the shelves 3 and extends their service life. The fixing structure 4 has a groove 42 formed on the side facing the shelves 3. Multiple grooves 42 may be formed, corresponding one to each shelf 3. The end of a shelf 3 facing the fixing structure 4 is inserted into the groove 42, facilitating assembly of the fixing structure 4 and the shelves 3. The fixing structure 4 may be made of polystyrene (EPS) foam.

[0052] The catalytic box 5 is set so that the gas in the accommodating chamber 12 is suitable for flowing to the internal catalytic component 51 of the catalytic box 5 and contacting the catalytic component 51. The catalytic component 51 can purify harmful substances in the gas (such as volatile organic compounds (VOCs), which include hydrocarbons, aldehydes, esters, and benzenes). The purified gas flows into the accommodating chamber 12 to adjust the cleanliness of the gas in the accommodating chamber 12 (that is, to reduce the amount of harmful substances in the gas). This avoids the user from removing harmful substances in the gas when purchasing the refrigerator 100, avoids physical damage to the user, simplifies the steps for the user to clean the refrigerator 100, and improves the user's experience. Among them, the catalytic component 51 can be a catalytic cloth (for example, a catalyst coated on the surface of a non-woven fabric), activated carbon, etc., or a structural component thereof that can decompose volatile organic compounds (VOCs), but is not limited to this.

[0053] After refrigerator 100 is manufactured, fixed structure 4 with catalyst cartridge 5 is installed on shelf 3. During transportation of refrigerator 100, catalyst element 51 purifies the gas in accommodating chamber 12. After refrigerator 100 arrives at the designated location, catalyst element 51 completes purification. After the user opens refrigerator 100, fixed structure 4 can be directly removed.

[0054] According to the refrigerator 100 of the present invention, the catalyst box 5 can purify harmful substances in the gas inside the refrigerator 100, preventing the user from absorbing harmful substances after opening the refrigerator 100, which is beneficial to protecting the user's health. In addition, it also simplifies the user's cleaning steps and improves the user's convenience.

[0055] According to some embodiments of the present invention, the catalyst member 51 includes a substrate (not shown), at least one edge of which is connected to the inner wall of the catalyst box 5. A catalytic layer (not shown) is formed on at least one surface of the substrate in the thickness direction.

[0056] For example, at least one side edge of the substrate in the circumferential direction is connected to the inner wall surface of the catalyst box 5, or multiple side edges of the substrate in the circumferential direction are connected to the corresponding inner wall surfaces in the catalyst box 5. The catalytic layer is formed on one side surface of the substrate in the thickness direction, or the catalytic layer is formed on both side surfaces of the substrate in the thickness direction. In this way, the substrate supports the catalytic layer, improves the structural strength of the catalytic component 51, and thus extends the service life of the catalytic component 51. Moreover, the substrate facilitates the connection between the catalytic component 51 and the inner surface of the catalyst box 5. In addition, the catalytic layer can also be directly in contact with the gas in the accommodating chamber 12, which is convenient for purification and also helps to improve the purification effect.

[0057] According to some embodiments of the present invention, the thickness of the catalytic layer is d, where d satisfies the following: 30 μm ≤ d ≤ 100 μm. For example, when the catalytic layer thickness is less than 30 μm, the thickness of the catalytic layer is small, and the amount of catalytic layer is small, making it impossible to ensure that the catalytic layer can completely purify the harmful substances in the accommodating cavity 12. Harmful substances may remain in the refrigerator 100, and after opening the refrigerator 100, the user may absorb the harmful substances, which may affect the user's health. The user also needs to clean the refrigerator 100 themselves, which increases the cleaning process for the user. When the catalytic layer thickness is greater than 100 μm, the catalytic layer thickness is large, which means that the material used in the catalytic layer increases, increasing the production cost of the catalytic layer and the production cost of the catalyst cartridge 5. In addition, after the catalytic layer purifies the gas in the refrigerator 100, the catalytic layer can continue to purify the gas, resulting in waste of catalytic layer material. Therefore, by setting the catalytic layer thickness d to satisfy the following: 30 μm ≤ d ≤ 100 μm, the catalytic layer thickness is appropriately set, effectively ensuring that all harmful substances in the refrigerator 100 are purified, while avoiding waste of the catalytic layer, thereby improving the effective utilization rate of the catalytic layer. In addition, the material consumption of the catalyst layer is reduced, the production cost of the catalyst element 51 is reduced, and the production cost of the catalyst box 5 is reduced.

[0058] According to some embodiments of the present invention, referring to Figure 4 There are multiple catalyst elements 51, and the multiple catalyst elements 51 are arranged at intervals along the length direction of the catalyst box 5. For example, Figure 4 In the example, the catalytic element 51 is perpendicular to the upper or lower sidewall of the catalyst box 5. Multiple catalytic elements 51 are spaced apart in the left-right direction, forming an angle between the catalytic element 51 and the left or right sidewall of the catalyst box 5. This arrangement increases the contact area between the multiple catalytic elements 51 and the gas in the accommodating chamber 12, accelerating the decomposition of harmful substances in the gas and thereby enhancing the purification effect of the catalytic elements 51. Furthermore, the small cross-sectional area of ​​the catalytic element 51 makes it easier to control, reducing the difficulty of installing the catalytic element 51 and improving the efficiency of assembling the catalyst box 5 and the catalytic element 51. However, this is not a limitation.

[0059] According to other embodiments of the present invention, there are multiple catalytic components 51, and the multiple catalytic components 51 are arranged at intervals along the width direction of the catalytic box 5. For example, the catalytic component 51 is parallel to the front side wall or the rear side wall of the catalytic box 5, and the multiple catalytic components 51 are arranged at intervals along the front-to-back direction. With such an arrangement, the cross-sectional area of ​​the catalytic component 51 is larger, which is easy to produce, thereby improving the production efficiency of the catalytic component 51. In addition, the width of the catalytic box 5 is smaller than the length of the catalytic box 5, thereby reducing the number of catalytic components 51 to be installed, and further reducing the steps of repeatedly installing the catalytic component 51 into the catalytic box 5, reducing the complexity of installation, and improving the efficiency of installation. However, it is not limited to this. It should be noted that there is an angle between the catalytic component 51 and the front side wall or the rear side wall of the catalytic box 5, that is, the catalytic component 51 is arranged at an angle.

[0060] According to some further embodiments of the present invention, referring to Figure 5 There are multiple catalyst elements 51, and the multiple catalyst elements 51 are arranged at intervals along the height direction of the catalyst box 5. For example, Figure 5 In the example, the catalytic element 51 is parallel to the upper side wall or lower side wall of the catalytic box 5, and multiple catalytic elements 51 are spaced apart in the front-to-back direction. This arrangement allows the catalytic element 51 to have a larger cross-sectional area, making it easier to produce and improving the production efficiency of the catalytic element 51. In addition, the height of the catalytic box 5 is less than the length of the catalytic box 5, thereby reducing the number of catalytic elements 51 to be installed, thereby reducing the steps required to repeatedly install the catalytic element 51 in the catalytic box 5, reducing the complexity of installation, and improving installation efficiency. However, the present invention is not limited to this. It should be noted that an angle is formed between the catalytic element 51 and the upper side wall or lower side wall of the catalytic box 5, that is, the catalytic element 51 is arranged at an angle.

[0061] According to some embodiments of the present invention, referring to Figure 4 A through hole 52 is formed on the outer peripheral surface of the catalyst box 5, and the interior of the catalyst box 5 is connected to the accommodating chamber 12 through the through hole 52. Figure 4 In the example shown, through holes 52 are formed on the front, top, bottom, left, and right sides of the catalyst cartridge 5. Gas within the accommodating chamber 12 enters the catalyst cartridge 5 through the through holes 52 and comes into contact with the catalytic element 51. This arrangement effectively ensures that the gas contacts the catalytic element 51, facilitating gas purification and improving gas cleanliness. Furthermore, the through holes 52 are simple to design and form, thereby improving the production efficiency of the catalyst cartridge 5.

[0062] According to some embodiments of the present invention, referring to Figure 4 and Figure 5 , a mounting groove 41 is formed on the fixing structure 4, and at least a portion of the catalyst box 5 is fitted into the mounting groove 41. For example, Figure 4 and Figure 5In the example, the mounting groove 41 is formed on the front side or rear side of the fixed structure 4, and the end of the catalyst box 5 close to the fixed structure 4 fits into the mounting groove 41. In this way, the catalyst box 5 is mounted on the fixed structure 4 through the mounting groove 41, which enhances the installation stability of the catalyst box 5. The other part of the catalyst box 5 is exposed in the accommodating cavity 12, so that the gas in the accommodating cavity 12 can enter the catalyst box 5, achieving the effect of purifying the gas. It should be noted that a plurality of mounting grooves 41 are provided on the fixed structure 4, and a catalyst box 5 is installed in each mounting groove 41. For example, two mounting grooves 41 are provided on the front side of the fixed structure 4, and the two mounting grooves 41 are spaced apart in the up-down direction. Two mounting grooves 41 are provided on the rear side of the fixed structure 4, and the two mounting grooves 41 are spaced apart in the up-down direction. The mounting groove 41 is formed on the fixed structure 4 between two adjacent grooves 42.

[0063] According to some embodiments of the present invention, referring to Figure 4 , one side surface of the catalyst box 5 in the width direction contacts the bottom wall of the installation groove 41, and a first connecting structure 53 is provided on at least one side of the catalyst box 5 in the length direction. The catalyst box 5 is connected to the side wall of the installation groove 41 through the first connecting structure 53. For example, Figure 5 In the example, the rear side of the catalyst box 5 contacts the bottom wall of the mounting groove 41, and the first connecting structure 53 is formed on the left side or right side of the catalyst box 5. The end of the first connecting structure 53 away from the catalyst box 5 stops at the side wall of the mounting groove 41 to fix the catalyst box 5 in the mounting groove 41. In this way, the first connecting structure 53 plays a fixing role. The first connecting structure 53 strengthens the installation stability of the catalyst box 5 in the mounting groove 41, avoids the catalyst box 5 from falling off the fixing structure 4, and improves the stability of the use of the catalyst box 5. In addition, the stability of the installation of the catalyst box 5 is also enhanced. But it is not limited to this. At least one first connecting structure 53 is formed on the left side and the right side of the catalyst box 5, respectively, to further strengthen the installation stability of the catalyst box 5. Among them, the shape of the first connecting structure 53 can be a barb shape.

[0064] Further, refer to Figure 4 、 Figure 6 and Figure 7 The first connecting structure 53 includes a connecting piece 531. One side of the connecting piece 531 is connected to a side surface of the catalyst cartridge 5 in the longitudinal direction. The connecting piece 531 extends obliquely along the width of the catalyst cartridge 5, away from the fixing structure 4. The other side of the connecting piece 531 extends away from the side surface of the catalyst cartridge 5. As the catalyst cartridge 5 moves along the width of the catalyst cartridge 5 into the mounting groove 41, the sidewalls of the mounting groove 41 act on the connecting piece 531 to push it toward the center of the catalyst cartridge 5, and the connecting piece 531 abuts against the sidewalls of the mounting groove 41.

[0065] For example, in Figure 4 、 Figure 6 and Figure 7 In the example, one side of the connecting piece 531 is connected to the side wall of the catalyst box 5, and the other side of the connecting piece 531 extends obliquely from the back-to-front direction, away from the above-mentioned side wall of the catalyst box 5. During the process of installing the catalyst box 5 into the mounting groove 41 from the front-to-back direction, the side wall of the mounting groove 41 squeezes the connecting piece 531, causing the above-mentioned other end of the connecting piece 531 to move toward the direction close to the side wall of the catalyst box 5, and the other end of the connecting piece 531 rebounds and stops against the side wall of the mounting groove 41, thereby further strengthening the connection strength between the catalyst box 5 and the mounting groove 41. In addition, the connecting piece 531 has a simple structure and is easy to process, thereby improving the production efficiency of the first connecting structure 53. But it is not limited to this. For example, the length of the first connecting structure 53 can also be extended (such as Figure 8 to further enhance the connection stability.

[0066] According to some embodiments of the present invention, referring to Figure 9 and Figure 8 At least one second connecting structure 54 is provided on the surface of one side of the bottom wall of the catalyst box 5 facing the mounting groove 41, wherein one end of the second connecting structure 54 is connected to the catalyst box 5, and the other end of the second connecting structure 54 extends toward one side of the bottom wall of the mounting groove 41. When the catalyst box 5 is fitted in the mounting groove 41, at least a portion of the second connecting structure 54 is inserted into the bottom wall of the mounting groove 41.

[0067] For example, in Figure 9 and Figure 8 In the example, one end of the second connecting structure 54 is connected to the bottom wall of the catalyst box 5, and the other end of the second connecting structure 54 gradually increases in cross-sectional area and then gradually decreases in cross-sectional area in the direction away from the bottom wall of the catalyst box 5. In this way, the second connecting structure 54 further strengthens the connection strength between the catalyst box 5 and the mounting groove 41, further preventing the catalyst box 5 from falling off the fixed structure 4. However, this is not limited to this. It should be noted that multiple second connecting structures 54 can be provided. For example, four second connecting structures 54 are provided, and the four second connecting structures 54 are respectively arranged at the four corners of the bottom wall of the catalyst box 5, further strengthening the connection between the catalyst box 5 and the bottom wall of the mounting groove 41.

[0068] According to the refrigerator 100 of the second embodiment of the present invention, Figure 1 , including a cabinet body, a door body 2, at least one shelf 3 and at least one fixing structure 4. The cabinet body is formed with an opening 11, and the door body 2 is arranged at the opening 11 for opening and closing the opening 11. The door body 2 and the cabinet body 1 jointly define a receiving cavity 12, and the shelf 3 is arranged in the receiving cavity 12. The fixing structure 4 is detachably arranged between the shelf 3 and the cabinet body for fixing the shelf 3 during transportation of the refrigerator 100.

[0069] The refrigerator 100 further includes a catalytic element 51 , which is placed in the accommodating cavity 12 or disposed on the fixed structure 4 .

[0070] For example, the catalytic element 51 can be placed directly within the accommodating chamber 12 or on the shelf 3 within the accommodating chamber 12, or the catalytic element 51 can be directly mounted on the fixed structure 4. In this arrangement, the catalytic element 51 directly contacts and purifies the gas within the accommodating chamber 12, thereby improving purification efficiency. Furthermore, this simplifies the production steps of the refrigerator 100 and improves the production efficiency of the refrigerator 100.
