Description

Technical Field

[0001] This utility model relates to tablecloth technology, and more specifically, to a heat-insulating tablecloth. Background Technology

[0002] A tablecloth is a tool specifically designed to protect a tabletop. Tablecloths not only enhance the aesthetics of a table but also prevent scratches from hard objects and stains from oil. Tablecloths are usually made larger than the tabletop to better cover it.

[0003] When bowls and plates containing freshly cooked food are placed on the table, the heat will be transferred from the bowls and plates to the tablecloth, and then from the tablecloth to the table, easily leaving marks on the table and affecting the tablecloth's protective effect on the table.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat-insulating tablecloth.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat-insulating tablecloth, comprising a surface layer and a bottom layer, wherein the surface layer has a plurality of raised strips on the side facing away from the bottom layer, and a cavity extending through the length of the raised strips is formed in the raised strips; the surface layer has a plurality of heat-insulating strips on the side facing the bottom layer, and the plurality of heat-insulating strips form a plurality of heat-insulating cavities between the surface layer and the bottom layer; and the bottom layer has anti-slip blocks for contacting the tabletop.

[0007] The present invention is further configured such that: the heat insulation strip has a perforation that connects two adjacent heat insulation cavities.

[0008] The present invention is further configured such that the distance between two adjacent protrusions is less than the width of the protrusion.

[0009] The present invention is further configured such that a waterproof coating is applied to the surface layer near the raised strip.

[0010] The present invention is further configured such that: the surface layer includes thermally conductive warp yarns and structural weft yarns, and the length direction of the convex strip is consistent with the weaving direction of the thermally conductive warp yarns.

[0011] The present invention is further configured such that the diameter of the thermally conductive warp yarn is greater than the diameter of the structural weft yarn, and the thermally conductive warp yarn includes a metal yarn core and a winding yarn wound on the metal yarn core.

[0012] The present invention is further configured such that: the structural weft yarn is made of several polyester fibers twisted together, the winding yarn is made of several irregularly shaped polyester fibers twisted together, and the cross-section of the irregularly shaped polyester fibers is Y-shaped.

[0013] In summary, this utility model has the following beneficial effects:

[0014] The air in the cavity can slow down the rate at which heat is transferred to the surface. When the ridge is subjected to pressure from the dishes, it can deform to a certain extent, increasing the contact area between the ridge and the dishes, reducing the possibility of relative sliding between the dishes and the ridge, and improving the anti-slip performance of the tablecloth. The air retained in the insulation cavity further slows down the rate at which heat is transferred to the bottom layer, improving the insulation performance of the tablecloth.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A type of heat-insulating tablecloth, such as Figure 1 and Figure 2As shown, the tablecloth includes a top layer 1 and a bottom layer 2. Several raised strips 3 of the same length as the top layer 1 are adhered to the side of the top layer 1 facing away from the bottom layer 2. Each raised strip 3 has a cavity 4 extending through its length. Specifically, several pieces of heat-resistant modified TPU are bent and adhered to the top layer 1 to form the raised strips 3. Since air is retained in the cavity 4, and air is a poor conductor of heat, it effectively slows down the transfer of heat from the dishes to the top layer 1 through the raised strips 3. Simultaneously, the raised strips 3 made of this material have good flexibility; when subjected to pressure from dishes, they can deform to a certain extent, increasing the contact area between the raised strips 3 and the dishes, reducing the possibility of relative slippage between the dishes and the raised strips 3, and improving the anti-slip performance of the tablecloth. Several heat-insulating strips 5 are adhered to the side of the top layer 1 facing the bottom layer 2. The tablecloth includes interlaced warp and weft strips, and several heat-insulating strips 5 forming several heat-insulating cavities 6 between the surface layer 1 and the bottom layer 2. Air is also retained in the heat-insulating cavities 6, further slowing down the speed at which heat is transferred to the bottom layer 2 and improving the heat insulation performance of the tablecloth. The bottom layer 2 is provided with anti-slip blocks 7 for contact with the tabletop. Specifically, anti-slip rubber is bonded to the bottom layer 2 to form anti-slip blocks 7. The anti-slip blocks 7 can increase the friction between the bottom layer 2 and the tabletop, reducing the possibility of relative movement between the tablecloth and the tabletop. At the same time, when the anti-slip blocks 7 contact the tabletop, a certain gap is also formed between the bottom layer 2 and the tabletop. Air is also retained in the gap, which slows down the speed at which heat is transferred from the bottom layer 2 to the tabletop to a certain extent, thereby ensuring the heat insulation performance of the tablecloth and ensuring the tablecloth's ability to protect the tabletop.

[0021] like Figures 1 to 3As shown, the heat insulation strip 5 has perforations 8 connecting two adjacent heat insulation cavities 6. When heat from the dishes is transferred to the heat insulation strip 5, this heat heats the air in the heat insulation cavity 6, causing the air to expand. The perforations 8 allow the expanded air to escape, reducing the possibility of deformation of the heat insulation strip 5 and the surface layer 1 due to air expansion. Simultaneously, the air that can circulate between adjacent heat insulation cavities 6 accelerates heat dissipation, effectively reducing the heat transferred to the bottom layer 2 and ensuring the heat insulation capacity of the surface layer 1. The distance between two adjacent protrusions 3 is less than the width of the protrusion 3. This design ensures that when the protrusion 3 deforms under the pressure of the dishes, the adjacent protrusions 3 will... The friction between the ridges prevents the cavity 4 in the ridge 3 from being flattened, ensuring that the air in the cavity 4 slows down heat transfer. The surface layer 1, near the ridge 3, is coated with a waterproof layer made of PVDC material. This waterproof coating prevents water or oil from seeping into the surface layer 1, facilitating cleaning and preventing water or oil stains on the tabletop. The surface layer 1 consists of heat-conducting warp yarns and structural weft yarns, woven together to form a plain weave. When the surface layer 1 receives heat from the ridge 3, it is transferred along the weaving direction of the heat-conducting warp yarns, causing some heat to be dissipated during transfer, reducing heat transfer from the surface layer 1 to the bottom layer. The heat on the 2nd layer is transferred along the length of the convex strip 3, which is aligned with the weaving direction of the heat-conducting warp yarn. This arrangement results in a larger overlap area between the convex strip 3 and the heat-conducting warp yarn, increasing the speed at which heat is transferred along the heat-conducting warp yarn. The diameter of the heat-conducting warp yarn is larger than that of the structural weft yarn. The heat-conducting warp yarn includes a metal core 9 and a winding yarn 10 wound around the metal core 9. Specifically, the metal core 9 is formed by twisting several metal fibers. The metal fibers are based on polyester fibers, with a metal coating applied to the surface of the polyester fibers. This arrangement gives the metal core 9 a metal-like thermal conductivity, ensuring the heat-conducting warp yarn's ability to conduct heat. The winding yarn 10 provides protection for the metal core 9, reducing heat loss. The possibility of metal coating peeling off the surface of low-metal fibers is reduced, ensuring the performance of metal yarn core 9. The structural weft yarn is made of several twisted polyester fibers. Polyester fibers have good plasticity, and the structural yarn made of this material allows the surface layer 1 to recover its shape quickly after bending, making the tablecloth less prone to wrinkles. The winding yarn 10 is made of several twisted irregular polyester fibers. The irregular polyester fibers have a Y-shaped cross-section, which has a large surface area. The winding yarn 10 made of this material also has a large contact area with air, which is conducive to the heat dissipation of the winding yarn 10, reducing the heat transferred to the bottom layer 2, and ensuring the overall heat insulation capacity of the tablecloth.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
