Description

Technical Field

[0001] This utility model relates to the technical field of furniture, specifically to a wooden furniture component with a moisture-proof structure. Through structural improvements, the furniture component possesses certain moisture-proof and mildew-proof functions. Background Technology

[0002] Some families require modular panel furniture components that integrate beds, wardrobes, storage cabinets, and bookcases, such as in children's rooms. Due to their high integration, these furniture components save space. However, on the other hand, this also means that deformation of one component due to moisture can affect other components.

[0003] Existing technologies use moisture-resistant agents to treat wood-based panels to give panel furniture a certain degree of moisture and mildew resistance. For example, the technical solution disclosed in utility model patent application CN104385426A, entitled "A Moisture-Resistant Artificial Fiberboard Furniture," involves furniture made from artificial fiberboard. The artificial fiberboard is produced by crushing the material, applying adhesive, laying it, and hot-pressing it. The adhesive used is a water-based vinyl ester polyurethane adhesive, and a moisture-resistant agent is added to the water-based vinyl ester polyurethane adhesive at a mass ratio of 1:(0.1-0.2). Through this method, moisture-resistant artificial fiberboard furniture possesses high strength, corrosion resistance, moisture resistance, and environmental friendliness. However, in practical use, the moisture resistance of artificial boards prepared from adhesives with added moisture-resistant agents is limited. One reason is that the amount of desiccant added is extremely small compared to the amount of wood fiber used. The ratio of wood fiber, adhesive, and desiccant is 100:5:(0.5~1). At this ratio, the desiccant is encapsulated by the adhesive and has difficulty contacting the moisture in the wood fiber. Another reason is that after the desiccant absorbs moisture from the wood fiber, the moisture still needs to return to the wood fiber before being discharged outward. Therefore, the above technical solution is not practical.

[0004] Existing technologies use antifungal agents to treat wood-based panels, giving panel furniture a certain degree of moisture and mildew resistance. To ensure the products and their production processes are environmentally friendly, existing technologies provide non-toxic antifungal agents. For example, the utility model patent application CN106217542A, entitled "Environmentally Friendly Long-Lasting Nano-Silver-Based Antibacterial and Antifungal Agent for Wood and Bamboo and Its Preparation Method and Application," discloses an antifungal agent for wood materials. This agent is made from raw materials including carboxymethyl chitosan, silver salt, and a reducing agent; the mass ratio of carboxymethyl chitosan, silver salt, and reducing agent is 1:(0.1~1):(0.05~5). The antifungal agent described above has broad-spectrum efficacy, strong anti-leaching properties, and long-lasting antibacterial effect. It can be used to treat wood, bamboo, straw, and other plant fiber materials using various methods such as soaking, spraying, brushing, vacuum treatment, and pressure impregnation. However, the aforementioned mildew inhibitors are relatively expensive, which correspondingly increases the price of wood-based panels using them. This makes these panels unsuitable for the low-cost, high-performance requirements of school furniture. Furthermore, relatively inexpensive mildew inhibitors themselves are somewhat toxic, and their production process (impregnation) can easily cause environmental pollution, making it difficult for the products and their production process to meet the requirements of green production.

[0005] Existing technologies also offer methods to improve the structure of furniture components to give them a certain degree of mildew resistance. For example, the utility model patent with publication number CN210433178U, entitled "A Multifunctional Modular Student Bed," discloses a moisture-proof base and a heating device. This type of moisture-proof base provides some degree of moisture and mildew resistance by preventing the modular cabinet from being placed directly on the ground, but it is difficult to completely isolate the moisture in humid air from affecting the wooden boards. At the same time, the heating device can increase the air temperature around the school furniture to some extent, but when the wooden boards have high humidity, the higher temperature actually increases the likelihood of mold growth.

[0006] In summary, there is a lack of green, environmentally friendly and relatively low-cost improvement methods in the existing technology to enable wooden furniture components to have certain moisture-proof and mildew-proof properties. Utility Model Content

[0007] The technical objective of this utility model is to overcome at least one of the above-mentioned technical problems and provide a wooden school furniture component with a moisture-proof structure.

[0008] To achieve the above-mentioned technical objectives, the first aspect of this utility model provides a wooden school furniture assembly with a moisture-proof structure, which includes at least a frame, a bed board installed through the frame, and a combination cabinet placed in the space below the bed board. The combination cabinet is suspended, and the back panel of the combination cabinet includes a back panel body and an airflow channel arranged along the z-axis on the back panel body. The lower end of the airflow channel is connected to the outside.

[0009] Through the above structure and the setting of airflow channels that connect with the outside, a certain degree of air circulation is achieved inside the back panel, which is usually prone to moisture and mold. This air exchange promotes the exchange of moisture between the back panel and the outside, reduces its moisture content, achieves a moisture-proof effect, and thus prevents mold growth.

[0010] Preferably, the frame includes a pair of first and second crossbeams arranged along the x-axis. The first crossbeam includes a tube forming an internal cavity and a first through hole opened on the lower wall of the tube. The upper end of the airflow channel communicates with the internal cavity through the first through hole.

[0011] Preferably, the frame also includes a mounting beam and a ventilation beam that connect the first crossbeam and the second crossbeam along the y-axis. The bed board is mounted through the mounting beam. The ventilation beam is set at a height lower than the mounting beam. The ventilation beam is a hollow tube with multiple ventilation openings on its top surface. A second through hole is provided on the inner wall of the tube. One end of the ventilation beam is connected to the tube through the second through hole.

[0012] Preferably, the upper end of the airflow channel is fixedly connected to the first through hole by a connector, the connector including a first connector inserted into the airflow channel, a second connector inserted into the first through hole, a gasket connecting the first connector and the second connector, a communicating cavity, and a flow guiding component disposed in the communicating cavity.

[0013] Preferably, the connecting cavity includes a first cavity segment, a second cavity segment, and a third cavity segment located at the length segments of the first connector, the second connector, and the gasket, respectively. The inner diameter of the third cavity segment is larger than that of the first cavity segment and the second cavity segment. The flow guiding component includes shaftless fan blades rotatably mounted on the inner wall of the third cavity segment.

[0014] Preferably, the lower end of the airflow channel is connected to the outside via a base.

[0015] Preferably, a temperature regulating device is also provided in the space below the bed board; the base has a base opening, which is oriented toward the temperature regulating device.

[0016] Preferably, the airflow channel is located on the back side of the back plate body.

[0017] Preferably, the airflow channel is a half-circular groove.

[0018] Preferably, the x-axis direction, the y-axis direction, and the z-axis direction are all perpendicular to each other.

[0019] In summary, the wooden school furniture component with a moisture-proof structure proposed in this utility model application has at least the following advantages:

[0020] 1. This design utilizes air exchange to promote moisture exchange between the back panel and the outside environment, thereby reducing its moisture content and achieving a moisture-proof effect for the modular cabinet, thus preventing mold growth. In particular, the moisture-proof performance is achieved through structural improvements, which will not have a negative impact on the green and environmentally friendly production process.

[0021] 2. Furthermore, by cooperating with a temperature control device, airflow can be generated and flow into the airflow channel through the base opening. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0034] Example 1: Refer to Figure 1 The illustration shows a wooden school furniture assembly with a moisture-proof structure. It comprises furniture elements largely similar to those in the prior art, including, for example, a frame 1, a bed board 2 mounted on the frame 1, a combination cabinet 3 located beneath the bed board 2, and a tabletop 6. The combination cabinet includes, but is not limited to, a wardrobe 3a on one side of the space beneath the bed board 2, a storage cabinet 3b on the other side, and a bookcase 3c suspended between the wardrobe 3a and the storage cabinet 3b. The wardrobe 3a and the storage cabinet 3b are also suspended. The tabletop 6 may consist only of a wooden board suitable for writing, or it may include a desk drawer suspended beneath the tabletop 6 body.

[0035] This embodiment uses wardrobe 3a as an example to specifically illustrate the moisture-proof structure of the wooden school furniture components in this case.

[0036] Reference Figure 2 As shown, the back panel 31 of the wardrobe 3a includes a back panel body 311 and an airflow channel 312 disposed within the back panel body 311 along the z-axis. Since the wardrobe 3a is suspended, the lower end of the airflow channel 312 can communicate with the outside.

[0037] In hot and humid climates, dormitory floors and walls are in a state of high humidity. The back panel 31 of the wardrobe 3a is flush against the wall, easily absorbing moisture from the wall and remaining in a high-humidity state. Furthermore, due to the lack of air circulation between the back panel 31 and the wall, it is prone to mold growth. In this embodiment, the structure described above, through the airflow channel 312 connecting to the outside, allows for a certain degree of air circulation within the typically damp and moldy back panel 31. This air exchange promotes moisture exchange between the back panel 31 and the outside environment, reducing its moisture content and achieving a moisture-proof effect, thereby preventing mold growth.

[0038] The airflow channel 312 within the back panel body 311 can be formed in various ways. In this embodiment, the back panel 31 is a hollow fiberboard or hollow particleboard with embedded PVC pipes, and the cavity of the PVC pipes serves as the airflow channel 312. Preferably, the inner wall of the PVC pipes has a moisture-absorbing layer, which is a coating of a desiccant. This moisture-absorbing layer can absorb moisture from the back panel body 311 to reduce the moisture content of the back panel body 311, and can regain its moisture-absorbing capacity when the surrounding environment becomes relatively dry and dry air flows into the airflow channel 312.

[0039] The lower end of the airflow channel 312 can be directly connected to the outside, or it can be connected to the outside through the base 7. (Refer to...) Figure 8 As shown, the base 7 has a hollow structure and a base opening 74 is formed inward in the x-axis direction. The base 7 includes a base body 71, a front boss 72 disposed on the front side of the base body 71, and a rear boss 73 disposed on the rear side of the base body 71. The rear boss 73 supports the back plate 31, and the surface of the rear boss 73 has multiple through holes that communicate with the opening at the bottom of the airflow channel 312.

[0040] Preferably, combined with Figure 1 , Figure 3 and Figure 4 As shown, the frame 1 includes a pair of first crossbeams 11 and second crossbeams 12 arranged along the x-axis, and a mounting beam 13 and a ventilation beam 14 connecting the first crossbeams 11 and second crossbeams 12 along the y-axis. The first crossbeam 11 includes a tube body 112 forming an internal cavity 111, and a first through hole 113 opened on the lower tube wall of the tube body 112. The upper end of the airflow channel 312 communicates with the internal cavity 111 through the first through hole 113. The two ends of the first crossbeam 11 are welded to the vertical beam, so the two ends of the first crossbeam 11 are closed.

[0041] Reference Figure 5 , Figure 6As shown, the ventilation beam 14 is positioned at a lower height than the mounting beam 13. Preferably, the ventilation beam 14 and the mounting beam 13 are spaced apart. Thus, the bed board 2 is mounted via the mounting beam 13; in other words, the bed board 2 is placed on a supporting plane composed of multiple mounting beams 13, and there is a gap between the back of the bed board 2 and the top surface of the ventilation beam 14. The ventilation beam 14 is a hollow tube with multiple ventilation openings 141 on its top surface. A second through hole 114 is provided on the inner wall of the tube body 112, and one end of the ventilation beam 14 communicates with the tube body 112 through the second through hole 114, i.e., with the internal cavity 111.

[0042] In this preferred embodiment, the external space, airflow channel 312, internal cavity 111, and ventilation beam 14 are interconnected, thereby further enabling the formation of circulating air on the back of the bed board 2. This air exchange promotes the exchange of moisture between the bed board 2 and the outside environment, reducing its moisture content and achieving a moisture-proof effect, thus preventing mold growth.

[0043] More preferably, refer to Figure 7 As shown, the upper end of the airflow channel 312 is fixedly connected to the first through hole 113, and one end of the ventilation beam 14 is fixedly connected to the second through hole 114 via connectors 4. Connector 4 is a plastic part and includes a first connector 41 inserted into the airflow channel 312, a second connector 42 inserted into the first through hole 113, a gasket 43 connecting the first connector 41 and the second connector 42, a connecting cavity, and a flow guide 44 disposed in the connecting cavity. The connecting cavity includes a first cavity section, a second cavity section, and a third cavity section located along the lengths of the first connector 41, the second connector 42, and the gasket 43, respectively. The inner diameter of the third cavity section is larger than that of the first cavity section and the second cavity section. The flow guide 44 includes shaftless fan blades rotatably mounted on the inner wall of the third cavity section.

[0044] Looking back Figure 1 As shown, the wooden school furniture assembly of this embodiment also includes a temperature regulating device 5 disposed in the space below the bed board 2, specifically, it is disposed below the tabletop 6. The temperature regulating device 5 can be of the prior art, such as the structure disclosed in utility model patent with publication number CN210433178U, which is a prior art graphene heating plate. By setting the temperature regulating device 5, when it heats the space below the tabletop 6, the airflow caused by the temperature difference can promote airflow between the external space, the airflow channel 312, the internal cavity 111, and the ventilation beam 14.

[0045] Preferably, the temperature regulating device 5 includes a device frame, a graphene heating plate mounted through the device frame, and a vertical fan blade mechanism disposed at the front end of the graphene heating plate. The vertical fan blade mechanism is a prior art technology and can blow the hot air generated by the graphene heating plate to the left and right, thereby directing the hot air toward the base opening 74.

[0046] In this embodiment, the x-axis, y-axis and z-axis are perpendicular to each other. In other embodiments, the x-axis, y-axis and z-axis may also be at other angles to each other.

[0047] Those skilled in the art can use the same structure to improve the back panel structure of the locker 3b.

[0048] Example 2: The difference between Example 2 and Example 1 is that, referring to... Figure 9 As shown, the airflow channel 312 is milled into the back of the back plate body 311, and the airflow channel 312 is a half-circular groove. The lower end of the airflow channel 312 communicates with the outside through the base 7, and the upper end of the airflow channel 312 is welded to the first crossbeam 11 to be closed. A temperature regulating device 5 is provided below the table 6.

[0049] The above description is for illustrative purposes and not for limitation. Many embodiments and applications beyond the provided examples will become apparent to those skilled in the art upon reading the above description. Therefore, the scope of this teaching should not be determined by reference to the above description, but rather by reference to the appended claims and the full scope of their equivalents. For purposes of completeness, all articles and references, including patent applications and publications, are incorporated herein by reference.
