DE2541543A1 - Chair with built-in heating system - heats occupant or chair by direct contact to save energy on room heating - Google Patents

Abstract

Healing devices such as heater elements, or warn air heaters are installed in the seats, backrests or arms of chairs so that the sitter is kept at a comfortable temperature while the rest of the room is kept at a lower temperature. The heating elements may consist of wires, tubes or foils. Conducting plastics elements may be used. An alternative method of heating may involve blowing hot air through pipes in the chair. Heating the chair rather than the whole room may lead to considerable savings in energy.

Description

Heatable furniture

The energy situation that will certainly continue to deteriorate in the future calls for the introduction of further energy-saving measures. Not just increasing Shortage of fossil fuels and the environmental problems that bring with them nuclear Energy generation, but also the growing cost burden on individual households requires solutions to reduce energy consumption.

It is a fact that by far the largest share of the total energy requirement must be provided for heating purposes.

Because of this, savings are needed for heating purposes Energy is of interest in general and in the private sector if it is a percentage little potential for savings for a large part of heating energy consumers is tapped.

Such a saving is particularly interesting when on the one hand achieved with little effort, on the other hand without impairing the comfort can be.

It is known that a lowering of the room temperature by a few Grade allowed very substantial savings in heating costs. The lowering of the room temperature or the renouncement of space heating in the relatively long transition periods but usually causes an unbearable loss of comfort. From one such a measure alone cannot therefore be expected to solve the problem.

On the other hand, it is also a fact that a decreased Room temperature is not perceived negatively by moving people. Uncomfortable the lowered temperature is only felt when one more or less sitting motionless.

The obvious conclusion is that you have to get through to the seated person Targeted heat supply the feeling of comfort despite reduced general Return room temperature.

The energy-saving goal must be retained, namely as far as possible to supply most of the heat energy directly to the human body.

The safest way to do this is to work with the body parts of the furniture that come into contact or that surround them for comfort necessary temperature. Accordingly, they are those facing the body Parts of the furniture or parts of these, in particular seats, backrests or also table surfaces to heat.

The particular advantage of such a solution lies precisely in the area of private households. Here, heat is often only required for a short time, e.g. for the Taking the morning meal or for a few people over a longer period of time, e.g. while sitting in front of the television in the evening. With appropriately designed seating furniture, Especially upholstered furniture can be made with economically viable investments in this way to private and macroeconomically interesting energy savings come.

All known constructions and systems can be used as radiators so z.t. Wires, pipes, foils, conductive plastics, hot air blowers, etc.

Electric power is the main source of energy come. But there are also other solutions, e.g. using warm air or in special cases conceivable through warm liquids.

The supply of electrical current can be flexible or permanently installed Cables. The transmission is also transformative, e.g. through into the Coil systems installed on the floor are possible.

When using hot air blowers, contact heating can be used instead a heat transfer can also take place through the incoming warm air.
