Abstract
The utility model relates to a constant-temperature electric air heater. After a heating element is connected with a conducting wire, the heating element is arranged in a shell body which is made of wood material. An insulation heat exchanger plate is arranged in the shell body, and the inner part of the shell body is filled with insulation heat-protective material. The utility model has the advantages of simple structure, low cost, convenient use, high safety, good heat-protective property and long heat-protective time, and the user feels safe. While in use, the utility model can be put under the table top, and an electric air heat-protective table can be manufactured. The utility model can also be put in a cotton cloth bag to be used as a hand and foot heater.
Description
The utility model is a kind of heating installation, belongs to the field of daily necessities.
Many electrothermal heating apparatus are arranged in the prior art, in general, they all are to be made into shell with metal material, though the shell heat transfer property of metal material is relatively good, but its heat insulation effect is undesirable, to the device of direct energising heating, the possibility that has the personnel that cause to get an electric shock, make the user that a kind of not too safe sensation is arranged like this, dare not use, buy this series products.
The purpose of this utility model be to invent a kind of with wood materials as the product casing material, in housing, be full of alumina-silicate ceramic fibre with insulating properties, product good insulation preformance, the heat insulation effect made like this are obvious, can overcome the problem that prior art exists.
The utility model is to constitute like this: with heater element (5) be placed in the housing (2) after lead (1) is connected, the upper and lower faces of heater element (5) is respectively laid an insulation heat transfer plate (3), fill full insulating heat insulating material (6) in the housing (2), heater element (5) can be a thermistor, housing (2) is made of wood materials, insulating heat insulating material (6) is an alumina-silicate ceramic fibre, between insulation heat transfer plate (3) and housing (2) heat transfer plate (4) is installed also.
Compared with prior art, the utility model is simple in structure, cheap, esy to use, safe and reliable, and good heat insulating, the temperature retention time of product are long, and safe sensation is arranged.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment of the present utility model: with two PTC(positive temperature coefficient demagnetization thermistors) back in parallel is connected with electric wire, put into then in the middle of the housing that is full of alumina-silicate ceramic fibre, housing is made with plank, installs insulation heat transfer plate of making of mica sheet and the heat transfer plate of making of iron sheet in housing.During use, this product is installed under the desktop, can be made into the electric heating thermal insulation table like this; This product is packed with cotton, can be used as the warmer of hand, pin; Utilize this product can also produce a series of series of products.
Claims (2)
1, a kind of constant temperature electric heating heating installation, it is characterized in that: with heater element (5) be placed in the housing (2) after lead (1) is connected, the upper and lower faces of heater element (5) is respectively laid an insulation heat transfer plate (3), fills full insulating heat insulating material (6) in the housing (2).
2, according to the described this constant temperature electric heating heating installation of claim 1, it is characterized in that: heater element (5) can be a thermistor, housing (2) is made of wood materials, insulating heat insulating material (6) is an alumina-silicate ceramic fibre, between insulation heat transfer plate (3) and housing (2) heat transfer plate (4) is installed also.
