Furniture with local heating site

 

(57) Abstract:

Furniture with local heating unit is used in the manufacture of furniture for residential, industrial and office premises. Furniture made from panels of plastic, metal, chipboard (wood fiber) Board, plywood or parts of natural wood, contains heated by an electric current element in the form of a panel or panels, which is a constructive element in the case of furniture and is made of a layered material containing electrically conductive composite fibrous woven or non-woven layer, coated on two sides of the insulating layers of paper, fabric, wood veneer and/or polymer films, etc. Layers glued together or pressed after impregnation of organic thermosetting or thermoplastic resins. Device for supplying power to the heating element is made current-carrying metal strips located inside the heating element in contact with the conductive layer. Conductive and insulating layers can be deposited on one or both sides of the wood particle Board (wood-fibre the polymer film. Design furniture provides its operational reliability and safety. 1 C.p. f-crystals.

The invention relates to the production of everyday and special furniture.

Known office and home furniture, made of panels of plastic, metal, chipboard and fiberboard (FR 2693887 A1, 22.07.1992).

The disadvantage of this furniture is the lack of local heating of one or more surfaces of the shell, which is necessary, for example, when drying wet clothes in the wardrobe, heated bottom and/or lid of the Desk and seat and/or backrest of the seats in cold areas or in case of emergency turn off the Central heating in residential or industrial buildings.

Closest to the technical essence is furnished with local heating by the node that contains an electric heating element and a device for supplying power to the heating element (US 5214739 And 25.05.1993).

The disadvantage of this design solution is local heating of furniture is a complex design heating unit containing a rotary reflecting the sash, and high risk lesions, Leo animal.

The technical result achieved in this invention is improving the reliability of furniture by changing the design of local heating unit and increase its electrical safety.

This technical result is achieved by the fact that the furniture with local heating by the node that contains an electric heating element and device for power supply, according to the invention is made of panels of plastic, metal, chipboard or fiberboard, plywood or parts of natural wood, with at least one of the panels or panels of furniture serves as a heating element and made of a layered material containing electrically conductive composite fibrous woven or non-woven layer and located on two sides of its insulating layers of paper, fabric, wood veneer and/or polymer films, glued together or pressed after impregnation of organic thermosetting or thermoplastic resins, and a device for power supply made in the form of conductive metal strips arranged in contact with the conductive layer of the LOI deposited on one or both sides of the chipboard or fibreboard or solid wood boards and covered with an external decorative layer of paper and/or plastic.

Below are embodiments of the invention.

One of the panels on furniture or plug-in part (panel) is made of one or a group of layered materials in paper and/or fabric used for the manufacture of the heating element, containing the Central conductive layer of composite fibrous non-woven or woven material and with its two sides of the insulating layers of paper, glass, plastic film, wood veneer, etc., connected with insulating adhesives or by pressing the packets of sheets at a high temperature partial melting of at least one of the insulating layers (or after impregnation with thermosetting or thermoplastic resins) or printed on one or both sides are fibreboard (chipboard) panels or solid wood boards. Possible additional application of decorative layers of paper or plastic on the surface of the furniture panels.

Device for supplying power to the electrically conductive layer is made in the form of conductive metal strips, for example, of aluminum or copper foil, naloge Jamie strips converge along one side of the rectangle of electrically conductive material to mount the electric cord, transmitting electrical current to the heating element from the electrical outlet or power. Insulating layers of paper, glass, plastic film, wood veneer and/or fibreboard, chipboard or solid wood boards are also preferably rectangular in shape and dimensions slightly greater than the conductive layer, so that when the connection of all of the layers together conductive metal strips were located in areas not occupied conductive layer, not touching each other to prevent short circuits.

Example 1.

A Desk with a table top, made of chipboard with a decorative coating of plastic. The rear and/or side walls in the form of metal frames with lugs to which are fastened with screws through the insulating sleeve panels of chipboard coated on one side with layers of carbon fiber paper, paper dielectric coating and a layer of wood veneer, United adhesive layers, and these layers are turned radially split between bearings inside space of the table. Heating panels include network 220 or 110 volts.

Example 3.

Chair whose backrest and/or seat made of plywood on the basis of peeled veneer without laminating layers and a Central layer of carbon fiber paper, United by pressing at elevated temperature packages sheets impregnated with an organic resin. The heating elements are covered on one side with soft parallelnavi gasket and covered with upholstery fabric. To prevent fire strip heating element is powered by a voltage regulator 0 - 36 volts, powered by 220 volts through a reduction to 36 volt transformer.

1. Furniture from local heating of the node that contains an electric heating element and device for power supply, characterized in that it is made of panels of plastic, metal, chipboard or fiberboard, the fan is aprivately element and made of a layered material containing electrically conductive composite fibrous woven or non-woven layer and located on two sides of its insulating layers of paper, fabric, wood veneer and/or polymer films, glued together or pressed after impregnation of organic thermosetting or thermoplastic resins, and a device for power supply made in the form of conductive metal strips arranged in contact with the conductive layer.

2. Furniture under item 1, characterized in that the electrically conductive composite fiber woven or non-woven layer and insulating layers deposited on one or both sides of the chipboard or fibreboard or solid wood boards and covered with an external decorative layer of paper and/or plastic.
