Description

Technical Field

[0001] This utility model relates to the field of home decoration, and in particular to a melamine composite multilayer wooden door. Background Technology

[0002] Composite wood doors are solid or near-solid doors made primarily of wood, plywood, and other composite materials, with a surface layer of wood veneer or other covering materials. In solid wood composite doors, finger-jointed ordinary wood is often used as the base material, serving as structural connections and a frame to improve resistance to deformation. The engineered wood used is mainly medium-density fiberboard (MDF), which has uniform material properties, good milling performance, and can be used as decorative components.

[0003] For example, patent number 202123224846.8 discloses an impact-resistant and environmentally friendly wooden door, including a wooden door structure. The wooden door structure includes a polyurethane foam board, which is disposed inside the wooden door structure. Filling areas are provided on the left and right sides of the polyurethane foam board, and the filling areas are filled with a grid-like wooden door filler. A reinforcing keel is provided in the wooden door filler near the end of the filling area of ​​the polyurethane foam board. Decorative panels are provided on the front and back sides of the polyurethane foam board and the filling areas. The decorative panels include a waterproof board and a wood veneer. The inner side of the waterproof board is tightly attached to the polyurethane foam board and the filling area, and the wood veneer is tightly attached to the outer side of the waterproof board.

[0004] The above technical solution uses polyurethane foam board as the core board to improve the impact absorption capacity of the wooden door. At the same time, the filling area with embedded reinforcing keel is set on both sides of the polyurethane foam board to improve the overall strength of the wooden door.

[0005] However, due to the significant difference in expansion properties between metal parts and wood materials, both will experience varying degrees of bending, warping, twisting, and other deformations under the same humidity conditions, leading to the loosening of the connection structure. This phenomenon becomes more severe as the size of the cabinet door increases.

[0006] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a melamine composite multilayer wooden door to overcome the shortcomings of existing technologies.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] A melamine composite multilayer wooden door includes veneer laminated timber and hollow particleboard for the core layer. The veneer laminated timber is disposed at both ends of the core layer and serves as the frame material for the core layer. The hollow particleboard is disposed in the middle of the core layer.

[0010] Melamine decorative panels are provided on the front and back sides of the core board layer. The inner side of the melamine decorative panels is connected and fixed to the veneer laminate and hollow particleboard through a composite process. A flat-bottomed groove is opened on the outer side of the melamine decorative panels, and a decorative strip is installed in the flat-bottomed groove. A polyvinyl chloride layer is covered on the outer surface of the composite veneer laminate, hollow particleboard and melamine decorative panels.

[0011] Furthermore, the laminated veneer lumber and hollow particleboard are combined to form the core layer, and the laminated veneer lumber, hollow particleboard and melamine decorative panel are combined to form the door panel.

[0012] Furthermore, the flat bottom groove is provided along the length of the melamine decorative panel and extends to the top and bottom of the melamine decorative panel. The decorative strip is made of stainless steel. After the decorative strip is installed in the flat bottom groove, the top surface of the decorative strip is flush with the opening of the flat bottom groove.

[0013] Furthermore, the flat-bottomed grooves on the melamine decorative panel located on the rear side of the core board layer are symmetrically arranged.

[0014] In summary, this utility model has the following beneficial effects:

[0015] By using laminated veneer lumber and hollow particleboard as the core layer, with the laminated veneer lumber used for the frame and the hollow particleboard used to absorb deformation, and by laminating melamine veneer on the core layer, the structural strength is improved and the stability of the wooden door is guaranteed.
