Description

Technical Field

[0001] This utility model belongs to the field of cabinet door panels, and in particular relates to a cabinet door panel that is resistant to moisture and heat. Background Technology

[0002] With the evolution of home decoration trends, many families are using floor-to-ceiling wardrobes. A floor-to-ceiling wardrobe means that the top of the wardrobe reaches the ceiling. This not only increases the storage space of the wardrobe but also eliminates the gap between the wardrobe and the ceiling, resulting in a better aesthetic appearance. It also reduces the cleaning work of cleaning the dust accumulated on the top of the wardrobe, making it increasingly popular.

[0003] The structure of a floor-to-ceiling wardrobe includes a cabinet body with an opening on the front and multiple doors that rotate and open on the front of the cabinet body. Because floor-to-ceiling wardrobes are very tall, when the door panels used are continuous panels, that is, when there is only one door panel on the front of the cabinet body in the vertical direction, the corresponding door panel length is also very large. The door panel length is close to the height of the cabinet body, and the door panel is more prone to deformation.

[0004] For door panels made of solid wood, due to the anisotropy of solid wood, it deforms differently in different directions after absorbing moisture in a humid and hot environment, making it more prone to warping, cracking and other problems. It has poor resistance to damp heat and is generally not used as a door panel for floor-to-ceiling wardrobes. Even without considering the damp heat issue, the inconsistent bending resistance of solid wood in different directions will also make the door panel more prone to deformation.

[0005] For door panels made of MDF (medium-density fiberboard), the high-temperature and high-pressure recombining process results in a uniform and isotropic structure, leading to similar deformation in all directions after moisture absorption. However, its abundant microporous structure makes it more hygroscopic and causes greater expansion after moisture absorption, resulting in poor resistance to damp heat. Additionally, MDF has poor nail-holding power, often causing screws to slip and leading to the door panel detaching from the cabinet. Using high-density fiberboard would be more suitable if increased nail-holding power was needed, but this would increase the weight of the door panel, making it more prone to detachment and bending under gravity.

[0006] Of course, there are also door panels made with aluminum alloy frames and glass. These door panels do not have any problems with moisture and heat deformation and are very sturdy after installation. However, if the glass breaks, it may cut people. Many families, especially those with children, do not like this for safety reasons. Utility Model Content

[0007] The purpose of this invention is to provide a cabinet door panel that is resistant to humidity and heat. This invention has the advantages of being relatively safe to use, having good resistance to humidity and heat, being firmly installed, and not easily bent.

[0008] The technical solution of this utility model is as follows: A cabinet door panel resistant to moisture and heat includes a square high-density panel, a low-density panel inside the high-density panel, a grid skeleton inside the low-density panel composed of multiple longitudinal stiffeners and multiple transverse stiffeners, wood veneer covering both sides of the high-density panel in the thickness direction, an edge banding strip on the outer periphery of the high-density panel, and a waterproof adhesive layer on the inner side of both the edge banding strip and the wood veneer.

[0009] In the aforementioned heat-resistant cabinet door panel, one side of the longitudinal stiffener is provided with multiple first clearance grooves, and one side of the transverse stiffener is provided with a second clearance groove corresponding to the position of the first clearance groove, so that the longitudinal stiffener and the transverse stiffener are tightly fitted and inserted in the thickness direction of the cabinet door panel.

[0010] In the aforementioned heat-resistant cabinet door panel, the opening directions of the first clearance groove on adjacent longitudinal stiffeners are opposite.

[0011] In the aforementioned heat-resistant cabinet door panel, both the longitudinal stiffeners and the transverse stiffeners are provided with multiple through holes.

[0012] In the aforementioned heat-resistant cabinet door panel, multiple grooves are provided on both sides of the longitudinal stiffener and both sides of the transverse stiffener.

[0013] In the aforementioned heat- and moisture-resistant cabinet door panel, the high-density board is filled with wood particles.

[0014] In the aforementioned heat-resistant cabinet door panel, both the longitudinal stiffeners and the transverse stiffeners are made of aluminum alloy plates with a thickness of 2-3mm and a width of 2-3cm.

[0015] Compared to existing technologies, the main material of this invention is MDF (medium-density fiberboard), which will not shatter and cut people, making it safer to use. A waterproof adhesive layer covers the MDF, blocking moisture entry and improving the door panel's resistance to damp heat. This invention consists of an outer high-density board and an inner low-density board. The door is connected to the cabinet via the outer high-density board. The high density of the board provides good nail-holding power, and the addition of wood particles further enhances the nail-holding power, making the door firmly installed and less prone to falling off. The low-density board reduces the overall weight of the door panel, making it less likely to fall off after installation and less prone to bending under its own weight. Although the low-density board reduces the weight, the door panel, being a continuous panel, is generally over 2.5 meters long, resulting in a relatively large weight. Therefore, bending under its own weight is still possible. To address this, an internal aluminum alloy mesh frame is used to significantly increase the door panel's bending resistance while only slightly increasing its weight. In summary, this utility model has the advantages of being relatively safe to use, having good resistance to damp heat, being firmly installed, and not being easily bent. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0023] Example: A cabinet door panel resistant to moisture and heat, such as Figure 1 As shown, the structure includes a square-shaped high-density panel 1, with a low-density panel 2 inside the high-density panel 1. The interior of the low-density panel 2 contains a grid framework composed of multiple longitudinal stiffeners 3 and multiple transverse stiffeners 4. The ends of the longitudinal stiffeners 3 and the transverse stiffeners 4 extend out of the low-density panel 2 and insert into the high-density panel 1. Both the longitudinal stiffeners 3 and the transverse stiffeners 4 are made of aluminum alloy plates with a thickness of 2-3 mm and a width of 2-3 cm.

[0024] Both sides of the high-density board 1 are covered with wood veneer 9 that simultaneously covers the low-density board 2. The outer periphery of the high-density board 1 is provided with an edge banding strip 10. The inner side of the edge banding strip 10 and the inner side of the wood veneer 9 are both provided with a waterproof adhesive layer 11.

[0025] The longitudinal stiffener 3 has a plurality of first clearance grooves 5 on one side, and the transverse stiffener 4 has a second clearance groove 6 on one side corresponding to the position of the first clearance grooves 5, so that the longitudinal stiffener 3 and the transverse stiffener 4 are tightly fitted together in the thickness direction of the cabinet door panel.

[0026] The opening directions of the first clearance groove 5 on adjacent longitudinal stiffeners 3 are opposite.

[0027] Both the longitudinal stiffener 3 and the transverse stiffener 4 are provided with multiple through holes 7.

[0028] Multiple grooves 8 are provided on both sides of the longitudinal stiffener 3 and both sides of the transverse stiffener 4, so that both sides of the stiffener are wavy surfaces.

[0029] Both sides of the high-density board 1 are provided with wood veneer 9, the thickness of which is 0.8-1mm. Both the high-density board 1 and the low-density board 2 are bonded and fixed to the wood veneer 9.

[0030] The high-density board 1 is filled with wood particles. The shape of the wood particles is not limited; they can be in the form of flakes or blocks. Most of the wood particles have a volume greater than 0.1 cubic centimeters, but should not exceed 0.5 cubic centimeters as much as possible.

[0031] Preparation method: includes the following steps,

[0032] 1) First, obtain aluminum strip by aluminum extrusion, forming grooves 8 on both sides of the aluminum strip. Take wood fiber powder, add glue, and stir evenly to obtain the internal filler; take wood fiber powder and wood particles, add glue, and stir evenly to obtain the external filler.

[0033] 2) Cut and punch the aluminum strip to obtain longitudinal stiffener 3 and transverse stiffener 4.

[0034] 3) Combine the longitudinal stiffeners 3 and the transverse stiffeners 4 into a grid skeleton.

[0035] 4) Make a square mold with a height close to the thickness of the door panel. Place the grid frame in the center of the mold. You can place four small wooden pieces at the bottom of the grid frame to raise it so that the top surface of the grid frame is lower than the top surface of the mold and the bottom surface of the grid frame is higher than the bottom surface of the mold.

[0036] 5) The internal filler is added to the mold, corresponding to the mesh skeleton; the external filler is added to the mold, corresponding to the outer side of the mesh skeleton.

[0037] 6) Heating and flattening the inner and outer fillers to the same height as the mold, the inner filler is compacted to form a low-density plate 2 with a density of 300-400 kg / m³. 3 After the external filler is compacted, a high-density slab 1 is formed with a density of 800-1000 kg / m³. 3 Component 1 is obtained. Steps 4) to 6) above can be completed using common MDF production equipment.

[0038] 7) Hot-press and glue wood veneer 9 to both sides of component one. The grain direction of wood veneer 9 should be along the length of the door panel. The glue used should be waterproof, such as polyurethane glue, to obtain component two. Component two is kept in stock as a standard specification. Several standard specifications can be made in stock according to the common specifications and widths of commonly used door panels.

[0039] 8) Floor-to-ceiling wardrobes are generally made according to on-site measurements. Take component two and cut it in the length and width directions to form the required size, resulting in component three. When cutting, the grid frame should be maintained to avoid damage from the woodworking saw blade. This is also why the grid frame does not extend to the outer wall of the high-density board 1, leaving a reserved cutting area.

[0040] 9) Paint component three and attach edge banding strips to the four side walls of component three. The edge banding strips should be waterproof, such as those made of plastic. The adhesive used for bonding should also be waterproof to obtain the desired door panel. The door panel has two layers of waterproofing: the first layer is paint + edge banding strips, and the second layer is a waterproof adhesive layer 11.

[0041] Subsequently, the corresponding accessories are fixed to the door panel and connected to the cabinet. For example, when used as a hinged door, a hinge is fixed to one side; when used as a hinged door, track wheels are installed at both ends from the top. The through hole 7 allows the filler material on both sides of the rib plate to connect together, resulting in better overall door panel strength. The groove 8 increases the rib plate area, making the rib plate and filler material bond more firmly, further improving the overall door panel strength. The wood veneer 9 not only further increases the door panel strength, but more importantly, it prevents cracks from forming on the paint surface of the door panel, serving as a stabilizing layer for the paint.
