Description

A kind of temperature self controlled electrically-heated source

Technical field:

The utility model relates to a kind of electric calorifie installation.

Background technology:

In the prior art, Electric heating floor adopts all be the resistance material of permanent power as heater element, it can only be installed in the concrete.In concrete, heat spot is arranged, so it should not have contact in concrete, should not intersect, should not be overlapping, can not shear arbitrarily, can not spreading, so circuit arrangement is single, the defective of heating surface bad adaptability, and need a lot of thermostats and controlled the failure rate height.Must the on-site concrete cast when electric heating element is installed in addition, the work progress complexity, the design strength in house is wanted corresponding raising, thus the investment of new house to increase, old room then gravity load increase and can't transform.Particularly the ground heating time does not allow to cover, and it is long to start warm-up time, the heat that absorbs during startup and when inactive liberated heat bigger, cause the loss of heat energy very big.

Summary of the invention:

Technical problem to be solved in the utility model is: design a kind of temperature self controlled electrically-heated source, to solve the technical problem that heat-energy losses is big, own wt is big, failure rate is high that prior art exists, further improve the fail safe that electric heating appliance uses.

The technical scheme of the utility model technical solution problem is: it mainly is made up of end box, self-limited type ribbon heater and electric screen spare, its end box is the tabular box body that contains heat-insulation layer, its electric screen spare is the metal forming adhesive tape, its self-limited type ribbon heater is installed on the heat-insulation layer in the tabular box body by the metal forming adhesive tape, has the metal forming adhesive tape to be connected between the metal forming adhesive tape of adjacent fixed self-limited type ribbon heater.

The screen that has at least a self-limited type ribbon heater to be provided with is provided with earth tap.

The self-limited type ribbon heater is positioned between the double layer of metal foil belt.

Rigid plate can be equipped with in the top of tabular box body.

Self-limited type ribbon heater more than two is parallel to be installed in the tabular box body independently.

The connection-peg that is connected with the self-limited type ribbon heater is housed on the sidewall of tabular box body or draws lead.

Owing to adopt technique scheme, compared with prior art, can reach when being used in combination: 1, improved the installation adaptability of product, solved the technical problem of the utility model safety in utilization by the polylith utility model, need not thermostat is controllable temperature, can cover on the ground that is mounted.2, its startup warm-up time short, the heat that absorbs during startup and when inactive liberated heat less relatively, energy-saving and cost-reducing; 3, simple in structure, in light weight, can be widely used in and be used for indoor heating on indoor wall, dado, smallpox, the floor, also can be used as ground ice snow melt device and as heating, the attemperator of utensil, baking oven, greenhouse, swimming pool etc., practical wide; 4, be electrically connected easy for installationly, can adopt arbitrarily by connection-peg or connection-peg connecting line as required and connect, various ways such as serial connection forms the circuit that can satisfy various temperature levels and multiple occasion, and safe and reliable; But 5 several pieces, tens of, hundreds of are installed and are mated formation conveniently until large-area combine and assemble, and construction is simple.
