Abstract

The utility model provides an energy-saving, long-life electronic warmer. The utility model is characterized in that the case is rotary body or polyhedron, the heating element adopts semiconductor material particularly PTC semiconductors porcelain material, the space among the electrode plates and the heat generation components is isolated by high temperature insulation baffles, the heat generation component is fastened by the upper and lower press plate of the heat accumulator and is also provided with a temperature control power-cut circuit. The capital outlay is 0.01 yuan after energizing 10-15 minutes every time. The surface temperature can reach 60-80 DEG C and can be used for more than 3 hours after power-cut.

Description

Energy-saving, long-life electronic warmer

A kind of electric conversion efficiency height, energy-conservation, convenient, safety, long electric heater of life-span.

The utility model is a kind of electric heater.Form by shell body, insulation material, heat-storing material, heat generating components and temperature control circuit.Characteristics with electric conversion efficiency height, energy-conservation, long-lived, easy to use, safe, health.Belong to household appliance technical field.

Existing household warming is divided into medium type, fuel type, resistance wire hot type and semiconductor hot type basically.The seepage phenomenon often appears in the hot-water bottle of medium type, and uses trouble, temperature retention time weak point.Fuel type warmer ignition procedures is also inconvenient, and smoke pollution is arranged, and temperature retention time is not long yet, low, withstand voltage low, easy overheated the burning of resistance wire type electric conversion efficiency, and easy thermal oxide and life-span are not long.More than three types of warmers all have the expensive common fault of power consumption.As for the semiconductor warmer, only there is at present the indoor warm-air drier that continuous energising can operate as normal to come out, but heat release a few hours and the product that can arbitrarily use beyond example still still after the outage.

The utility model is at above-mentioned defective, utilization semiconductor heater element, particularly the PTC semiconductive ceramic is designed safe and reliable internal structure as heater element, is developed into the electric heater of electric conversion efficiency height, energy-conservation, long-lived, easy to use, safe, health.Be that example is illustrated with PTC semiconductive ceramic sheet below.

Electric heater of the present utility model is made up of shell, heat-insulation layer, heat storage, heat generating components and temperature control circuit.Its shell is made rotary body or polyhedron-shaped with metal or nonmetallic materials, and inner surface of outer cover is the thermal insulation coatings layer.Select for use the light material of good heat insulating to fill between shell and heat storage, form heat-insulation layer.Heat storage is made up of last lower platen and separators, selects the strong heatproof insulating material manufacturing of heat storage capacity for use.Heat generating components is made up of power-on and power-off pole plate, PTC semiconductive ceramic sheet, separators, PTC semiconductive ceramic sheet is positioned between two electrodes, with high-temperature electric conduction bonding agent or solid pressure method and battery lead plate realization Ohmic contact, isolated by separators between two electrodes and each PTC sheet, whole heat generating components is fastening by last lower platen.Temperature control circuit adopts the design of rated temperature outage mechanism, places in the heat-insulation layer between heat storage and shell.

Electric heater of the present utility model, main design parameters is that PTC sheet curie point is greater than 250 ℃, and is withstand voltage greater than 450V, warmer appearance and size, heat storage size and heat generating components watt level can freely be selected, and look the purposes difference and can be divided into large, medium and small type substantially.The utility model product that performance is similar to 300W resistance wire warmer, in conduction time, average power consumption is not more than 50W, and the electricity charge are lower than 0.01 yuan.Because PTC sheet automatic control current limliting when the warmer surface temperature is 60--80 ℃, can stop intensification automatically, therefore there is not overheated sorrow of burning.The average life span of PTC semiconductive ceramic sheet was not less than 5000 hours, and it is commeasurable that this is that any resistance wire does not have.Except that heater element automatic current limiting, the utility model product adopts the special isolation structure of temperature control power-down circuit and heat generating components, and what can guarantee to use is perfectly safe.

The using method of electric heater of the present utility model is easy arbitrarily, diverse in function.Connect power supply, indicator lamp is shinny, heater work, after 10--15 minute, the warmer surface temperature reaches 60--80 ℃, and this moment, temperature control circuit was cut off the electricity supply, indicator lamp extinguishes, and warmer can be separated power supply, arbitrarily uses, can warm up skill, can warm up quilt, can be used for indoor, also can go out to carry, look its product watt level and environment temperature and differ, the heating time is not waited, and generally is not less than 3 hours.

As mentioned above, goal of the invention of the present utility model all realizes.

Electric heater structure of the present utility model is shown in Figure of description.

Among the figure, 1 is shell, and 2 is the inner surface of outer cover heat insulation coating, and 3 is heat-insulation layer, and 4 is temperature control circuit, and 5 is the heat storage pressing plate, and 6 is battery lead plate, and 7 is PTC semiconductive ceramic sheet, and 8 is separators.

Now make embodiment for flying butterfly-shaped electric heater with profile as Figure of description.Shell thin aluminum sheet drawing, inner surface coated one deck thermal insulation coatings is handled with plastic-blasting or baking vanish in its surface.Heat-insulation layer material selection alumina silicate fibre.The heat storage parts form around knot with the big refractory insulating material of heat storage capacity.Power-on and power-off pole plate beryllium-bronze thin plate punching.As shown in drawings, after heater part assembling finished, fastening and place among the heat-insulation layer with lower platen on the heat storage.Temperature control and power circuit are installed between heat storage and shell.Seal shell at last.

Claims

The durable energy saving electric heater is characterized in that heater adopts semiconductor heater element, particularly PTC semiconductive ceramic element; Shell is made with metal or nonmetallic materials, is shaped as rotary body or polyhedron; Insulate between the semiconductor heater element and between the two-plate and isolate, whole heat generating components is fastening by the last lower platen of heat storage.
