Description

  TECHNICAL FIELD The present invention relates to a table warmer having a heating wire disposed inside a cooked food such as a table or a table cover that does not cool.

  Conventionally, when a heated food is left for a long time, it quickly cools, and it has been necessary to repeatedly heat or heat it. In addition, even when heated, there was a problem that in the cold season, it quickly cooled down during the meal and could not be eaten deliciously until the end.

  To that end, in addition to microwave ovens, devices such as desktop stoves and hot plates have been devised to make it difficult to cool meals.

  There has also been proposed a simple heating device with a stove built inside the center of the desk so that the pan placed in the center of the table gets hot. (See Patent Document 1)

JP 1996-163943 A

  However, there is a voice that the method of heating in the range will feel that even handmade dishes are the same as the bento and commercial products, and it is not something that keeps the heat insulation state of all food on the table for a long time In addition, the problem that the cooked food quickly cooled down when it was placed on the table was not solved.

  In addition, the stove and hot plate had the advantage of being able to eat dishes while being warm on the table, but there was no convenience to use them every day due to the trouble of putting in and out and washing each time.

  Similarly, in Patent Document 1, the built-in stove has a flat tabletop that is easy to use without taking in and out and is easy to clean. At the time of wearing in a bowl, the temperature of cooking decreased.

  Accordingly, an object of the present invention relates to a table warmer such as a table laid with a heating wire inside or a table cover having a function of maintaining a heat-retaining state of cooked food.

  The present invention provides a table warmer such as a lightweight table covering or table cover that has a heat generating wire inside, is excellent in heat retaining properties, is resistant to dirt and water, and is safe to touch by the human body. The purpose is to provide.

  In the present invention, it is possible to provide a heat-retaining appliance for a table that can be cooked and cooked with heat even when time passes.

  Further, according to the present invention, it is possible to reduce power consumption by dividing a large number of cooking dishes into a plurality of times and reheating them repeatedly, thereby obtaining an environment-friendly effect.

  According to the present invention, it is possible to provide a table warmer that is simply installed on a table and does not need to be taken in and out every time it is used or washed.

  Furthermore, the present invention can provide a table warming instrument that can be manufactured at a low cost, can be safely and comfortably, and can be used for a warm meal effectively because of its simple structure.

The perspective view of several patterns which arranged the heating wire of FIG. The perspective view of the arrangement pattern which divided the exothermic line of the present invention of Drawing 1 into four places. 1 is an overall perspective view showing an embodiment of a cover mold according to the present invention. The perspective view which opened the cover part of the steam hole of the main body upper surface of FIG. The perspective view of the other form of the cover type | mold of this invention. FIG. 8 is a perspective view of an arrangement pattern of heating lines in the cover mold F of FIG. 7. FIG. 8 is a perspective view of an arrangement pattern of heating lines in the cover molds G and H of FIG. 7.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In addition, the table warming utensil of this invention and its manufacturing method are not limited to an Example.

  First, the implementation method of the floor mold according to the present invention will be described in detail with reference to FIGS.

  FIG. 1 is an overall perspective view showing an embodiment of a spread type on a table or tabletop.

  FIG. 2 is a cross-sectional view that constitutes the present invention. The structure is such that a heat ray is arranged inside and the main body is warmed, and the front surface layer and the back surface layer are waterproofed. For example, it is not limited to a soft synthetic resin sheet. A water-repellent fiber cloth, a material such as a mat, or a hard plate-like material is used.

  In addition, as the heat wire of the heater wire of the main body, the nichrome wire, the composite heating fiber, and the metal wire may contain conductive metals such as palladium, rhodium, and platinum in addition to silver.

  Examples of the material of the fibrous nonwoven fabric constituting the inner layer 5 include various synthetic fibers such as polypropylene, polyacrylonitrile, polyamide, and polyvinyl chloride in addition to polyester.

  In addition, a heat generating sheet is formed on a soaking sheet made of a metal foil such as an aluminum foil to form a sheet-shaped heating element at a constant interval so that heat can be quickly transferred to all necessary portions. It is also preferable to increase the efficiency.

  A silicon plate or the like is used as a heat insulating material for the inner layer 7 that covers the heating wire from below.

  The heating wire 3 covers the heater wire with a resin 11 such as vinyl chloride. Further, it is preferable to use a wire whose surface 11 is covered with a polyethylene resin having a melting point lower than that of vinyl chloride.

  For example, wiring is performed on a wiring pattern as shown in FIG. 1 on a silicon plate or the like, a heat insulating material is placed on the wiring pattern, and hot pressing is performed, so that the polyethylene resin 11 covering the heater wire is melted. The heat insulating material of the inner layer 5 and the heating wire 10 as well as the inner layer 7 are bonded together.

  At that time, when a groove having the same width is formed in the silicon plate as the heat insulating material of the inner layer 7 covered from below and the heat generating line is formed by pressing the groove with the same width, the heating line is buried in the groove and is flat. It becomes possible to create a surface, and even if the sheet of the main body is bent, the heating wire is not shifted, or it is not cut by excessive pressure.

  The upper surface layer 4 and the lower surface layer 8 are preferably made of a water-repellent synthetic resin film that is easily bonded to a nonwoven fabric, such as a low-melting point copolyester, a low-melting polyolefin, or a low-melting copolyamide resin. Thermoplastic polyester resins such as polyalkylene terephthalate are easy to adopt because they have heat resistance, weather resistance, water resistance, chemical resistance, and solvent resistance.

  Moreover, you may mix | blend the flame retardant brominated polycarbonate, brominated epoxy, an antimony oxide compound, etc. as an additive of a surface layer.

  Next, FIG. 3 is a wiring diagram of the heating lines. In this way, the heating lines are arranged at regular intervals as a whole, and can be wired according to each location of the table or various wirings can be made.

  Also, the shape and size of the main body vary according to the size and shape of the table, and as in the embodiment of E in FIG. But it is possible.

  Further, FIG. 4 shows an embodiment of an arrangement of heat rays that generate heat only at an arbitrary location. For example, when only one person eats on a table, if all the ranges are heated, power consumption is wasted.

  Therefore, when it is desired to generate heat only for one person, for example, in order to generate heat only in the peripheral part of a above the main body in FIG. 4, only the energizing switch of the controller part a1 is energized. When it is desired to generate heat at the location, the energization switches of the controller units a1 and b1 may be energized.

  And when all the places are made to generate heat, it is sufficient to energize the energizing switches of all the controller sections. In this way, it is possible to achieve further efficient power consumption savings by arranging the heating lines that energize only necessary portions.

  Next, an embodiment of a cover-type main body will be described with reference to FIGS.

  First, FIG. 5 is an overall perspective view showing an embodiment of a cover type on a table or tabletop.

  A vapor hole 16 for releasing excess water vapor is provided in the upper part of the main body of FIG. 5, and the lid 14 can be slid open and closed as necessary with a fastener 15 as shown in FIG. 6.

  FIG. 7 shows an example of the cover type of the present invention in which the shapes are diversified. In this way, it is characterized by a table warming instrument that has a variety of materials and shapes, and that is equipped with a simple and convenient heat line suitable for the table and application.

  The cover-type material of the present invention is preferably made with excellent water repellency as in the case of the above-described lay-out type.

  As shown in FIG. 7, the shape and size of the embodiment of the main body cover type are various according to the size and shape of the table. Further, as in the embodiment H, it is also possible to use a cover-type table warming apparatus having a size that matches the floor mold of a small place mat for one person.

  In this way, by setting the main body as a spread mold and a cover mold, the cover mold or sheet mold of the present invention is installed on the top, and the sheet mold of the present invention is installed below, thereby preventing heat from escaping from the gap. In addition, an effective heat retention effect can be obtained by heat transfer of the heating wire.

  In addition, since the controller 2 can be attached to the end of the main body, an over-temperature prevention device (not shown) composed of a thermostat, a thermal fuse, or the like for stopping energization is provided in 9 shown in the sectional view of FIG. It is possible to prevent fires caused by abnormal heating.

As other additives for the surface layer and the inner surface layer of the present invention, impact resistance improver, toughness improver, antioxidant, UV absorber, heat stabilizer, weather stabilizer, lubricant, mold release agent, colorant, crystal A nucleating agent, a crystallization accelerator or the like may be added, or a treatment such as insect repellent, antifouling, deodorizing, or negative ion effect may be performed.
