For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0035] As Figure 1The utility model discloses an embodiment relates to a composite board for daily household electrical appliances, including composite board body 100 and anti deformation piece 200, and anti deformation piece 200 is used to improve the problem of bending and warping of composite board body 100 due to thermal expansion and cold shrink, wherein, the number of anti deformation piece 200 is two, and two anti deformation pieces 200 are arranged at the two ends of the length direction of composite board body 100 respectively, so that the problem of bending and warping of the two ends of composite board body 100 due to thermal expansion and cold shrink is further improved.

[0036] In combination Figure 1 With Figure 3 Anti deformation piece 200 includes connecting portion 210 and two clamping portions 220 connected to the two sides of connecting portion 210 along the thickness direction of composite board body 100, two clamping portions 220 are spaced apart and arranged side by side along the thickness direction of composite board body 100, connecting portion 210 is arranged opposite to the end of composite board body 100, and two clamping portions 220 are respectively located on the two sides of composite board body 100 along the width direction of composite board body 100, and two clamping portions 220 clamp composite board body 100.

[0037] It can be understood that connecting portion 210 is used to connect two clamping portions 220, and two clamping portions 220 clamp composite board body 100 together, so as to inhibit the bending and warping of the end of composite board body 100 due to thermal expansion and cold shrink.

[0038] Specifically, two clamping portions 220 are plate-shaped structures, and two clamping portions 220 are arranged in parallel, the distance between two clamping portions 220 is less than the thickness of the clamped area of composite board body 100, and two clamping portions 220 jointly apply force to composite board body 100 and clamp composite board body 100 to inhibit the bending and warping of the end of composite board body 100 due to thermal expansion and cold shrink.

[0039] It should be noted that the strength of anti deformation piece 200 is greater than that of composite board body 100, and the deformation amount of anti deformation piece 200 when heated or cooled is less than that of composite board body 100, which can further improve the inhibition effect of anti deformation piece 200 on the bending and warping of the end of composite board body 100 due to thermal expansion and cold shrink.

[0040] In combination Figure 1 , Figure 2 With Figure 6 Further, clamping portion 220 is provided with anti unhooking 221, and composite board body 100 is provided with clamping groove 101, anti unhooking 221 extends into clamping groove 101, so that anti deformation piece 200 can be prevented from being pulled out of composite board body 100.

[0041] Specifically, each clamping portion 220 is provided with an anti-escape hook 221 close to one side of the composite board body 100, the two sides of the composite board body 100 along the thickness direction are provided with clamping grooves 101, and the anti-escape hooks 221 on the two clamping portions 220 correspondingly extend into the clamping grooves 101 on the two sides of the composite board body 100. By making the anti-escape hooks 221 extend into the clamping grooves 101, the anti-deformation piece 200 can be prevented from moving along the length direction of the composite board body 100 and escaping from the composite board body 100.

[0042] Further, the anti-escape hooks 221 on each clamping portion 220 are correspondingly arranged with a group of clamping grooves, and each group of clamping grooves includes a plurality of clamping grooves 101 arranged along the length direction of the composite board body 100.

[0043] In combination Figure 8 With Figure 9 Further, the composite board for daily household appliances further comprises an abutting piece 300 connected to the anti-deformation piece 200 and abutting with the composite board body 100, so that the anti-escape hooks 221 are hooked with the groove walls of the clamping grooves 101, and the connecting portion 210 is spaced from the end of the composite board body 100 to form the air permeation gap 240.

[0044] It can be understood that the abutting piece 300 is used to apply a force to the anti-deformation piece 200, so that the anti-escape hooks 221 on the anti-deformation piece 200 are hooked with the groove walls of the clamping grooves 101, thereby avoiding loosening of the anti-deformation piece 200. In addition, under the action of the abutting piece 300, the connecting portion 210 can be spaced from the end of the composite board body 100 to form the air permeation gap 240. In this way, when the composite board body 100 expands or shrinks due to heat or cold, the gas inside the composite board body 100 can exchange with the outside through the end of the composite board body 100, thereby reducing the risk of bending and warping of the end of the composite board body 100.

[0045] Further, the connecting portion 210 is provided with a screw hole 211 extending along the length direction of the composite board body 100, and the abutting piece 300 is a screw, which is arranged in the screw hole 211 and abuts with the end of the composite board body 100. In this way, under the action of the screw, the anti-escape hooks 221 on the anti-deformation piece 200 can be hooked with the groove walls of the clamping grooves 101. In addition, by twisting the screw, the tightness between the anti-deformation piece 200 and the composite board body 100 can be adjusted.

[0046] In the embodiment, the screw hole 211 includes a threaded segment 2111 and an avoiding segment 2112 in communication with the threaded segment 2111, the avoiding segment 2112 is located outside the threaded segment 2111, the screw includes a threaded column 310 and a screw head 320 connected with the threaded column 310, the threaded column 310 is arranged in the threaded segment 2111 and makes the screw head 320 arranged in the avoiding segment 2112, so that the purpose of hiding the screw head 320 can be achieved.

[0047] like Figure 3 As shown, in some embodiments, a clearance groove 230 is provided on the inner side of the connection position between each clamping part 220 and the connecting part 210. The clearance groove 230 allows the clamping part 220 to fit more tightly with the composite board body 100, thereby better suppressing the bending and warping of the ends of the composite board body 100 caused by thermal expansion and contraction.

[0048] Understandably, in order to ensure that the two clamping parts 220 effectively clamp the composite board body 100, the distance between the two clamping parts 220 is less than the thickness of the area of ​​the composite board body 100 that is clamped. Without the clearance groove 230, gaps might occur. Figure 4 The problem is that the middle clamping part 220 is raised and cannot be tightly fitted with the composite board body 100.

[0049] It should be noted that, as Figure 3 As shown, although the edges of the upper and lower ends of the composite board body 100 cannot be clamped by the clamping part 220 after the clearance groove 230 is provided, the edge of the upper and lower ends of the composite board body 100 is already clamped by the clamping part 220, which can improve the risk of bending deformation of the area near the edge of the upper and lower ends of the composite board body 100, thereby reducing the risk of edge warping of the upper and lower ends of the composite board body 100.

[0050] Combination Figure 1 and Figure 7 In some embodiments, the clamping part 220 includes a main clamping part 222 and two extensions 223 connected to the main clamping part 222. The two extensions 223 are spaced apart along the width direction of the composite board body 100. The two extensions 223 can clamp the side edges of the composite board body 100, thereby reducing the risk of deformation and warping of the composite board body 100 on both sides along the width direction of the composite board body 100.

[0051] Combination Figure 1 , Figure 5 and Figure 7 Furthermore, the composite panel body 100 is provided with positioning grooves 102 on both sides along its thickness direction, and two clamping parts 220 are respectively disposed in the positioning grooves 102 on both sides of the composite panel body 100 along its thickness direction. The positioning grooves 102 are used to position the anti-deformation part 200 and prevent the anti-deformation part 200 from moving relative to the composite panel body 100 on both sides along its width direction.

[0052] like Figure 2As shown, in some embodiments, the composite board body 100 comprises a middle layer 110, and two outer layers 120 respectively arranged on both sides of the middle layer 110, wherein the middle layer 110 is a polypropylene honeycomb core, and the outer layer 120 is stainless steel.

[0053] It can be understood that the composite board body 100 adopts a symmetrical layer design, which can reduce warping by balancing the expansion stress in different directions, and in addition, the polypropylene honeycomb core can allow the internal gas to freely expand and contract under temperature difference, which can improve the problem of bulging.

[0054] In the composite board for daily household appliances of the utility model, the anti-deformation piece 200 is used for improving the problem of bending and warping of the composite board body 100 caused by thermal expansion and cold shrinkage. Specifically, the connecting part 210 of the anti-deformation piece 200 is used for connecting the two clamping parts 220, and the two clamping parts 220 jointly clamp the composite board body 100, so as to inhibit the bending and warping of the end part of the composite board body 100 caused by thermal expansion and cold shrinkage. Further, the anti-unhooking hook 221 is arranged on the clamping part 220, the composite board body 100 is provided with a clamping groove 101, the anti-unhooking hook 221 extends into the clamping groove 101, so that the anti-deformation piece 200 can be prevented from being unhooked from the composite board body 100. In addition, the abutting piece 300 is used for applying a force to the anti-deformation piece 200, so that the anti-unhooking hook 221 on the anti-deformation piece 200 is hooked tightly with the groove wall of the clamping groove 101, thereby avoiding the loosening of the anti-deformation piece 200, and in addition, under the action of the abutting piece 300, the connecting part 210 can be spaced apart from the end part of the composite board body 100 to form an air permeable gap 240, so that when the composite board body 100 occurs thermal expansion and cold shrinkage, the gas in the composite board body 100 can be exchanged with the outside through the end part, thereby reducing the risk of bending and warping of the end part of the composite board body 100. The composite board for daily household appliances of the utility model does not need to rely on too many bolts for installation, and the installation is simple.
