Description

Circulating electric heater

The utility model relates to circulating electric heater, and particularly a kind of cold air is entered by lower port, the circulating electric heater that hot-air flows out through upper port.

Common electric heater structure as shown in Figure 1, possesses a casing 1 substantially, be formed with big breach 11 on the casing 1, breach 11 places are provided with the iron rack 12 of heatproof, the casing 1 outer temperature adjusting switch 15 that is provided with, inside is provided with two electrothermal tubes 13,14 (or heating wire), and a radiator fan 16.During use, adjust temperature adjusting switch 15 and make

electrothermal tube

13,14 heatings, with the air heat of casing 1 inside, mat radiator fan 16 is discharged hot-air from breach 11 again; By this, room air is heated gradually.

Above-mentioned electric heater structure still has the disappearance that is not inconsistent utilization benefit:

1. only establish a breach, after air is heated, easily accumulate in the box house dead angle, be difficult for discharging, cold air is difficult for entering heating in the casing, makes room air heating poor effect.

2. see through electrothermal tube (or heating wire) thermal source conducted to air, because of the surface area of electrothermal tube and heating wire limited, so the efficiency of heating surface is low.

3. though the iron rack has heat-resisting effect, precisely because also good because of thermal conductivity, easily make user or child that danger such as scald take place.

4. after electrothermal tube or heating wire were heated, because of its surface is the condition of high temperature, during the water droplet of catching a cold accidentally contact, also ruptured or break because of embrittlement in its surface, so can not be installed in the heavier part of moisture (as the bathroom).

5. the box house hot-air needs the heat radiation of mat radiator fan, when fan rotates, and big and easy damage of noise.

The purpose of this utility model is to provide a kind of have upper and lower ventilating board, passage that natural convection air is good, quickening the air circulation heating, and is provided with conducting strip and enlarges heat-conducting area, improves the shield ring type electric heater of heat transfer efficiency.

The technical scheme that realizes above-mentioned purpose is: circulating electric heater comprises: panel, and drain pan and switch base is characterized in that:

One panel, the upper end is provided with ventilating board, is formed with mesh on the plate face of last ventilating board;

One drain pan, bottom face is provided with down ventilating board, on the plate face of following ventilating board mesh is arranged, and distance two side frames of the suitable distance of ventilating board down is respectively equipped with chimeric mouthful;

Two connecting supports, lateral margin has clip slot, and clip slot embeds chimeric mouthful of drain pan, and its perpendicular end surface is extruded with tank;

One heat conduction body is located at drain pan below, and both sides are provided with prominent tenon, and prominent tenon is inserted the tank of connecting support, wherein and have electrothermal tube to wear;

One switch base is located at place, end angle, which is provided with the thermoregulation knob power switch.

Wherein connecting support is provided with and can supplies to set firmly the cylindrical body and the drain pan lateral vertical of the line of induction for the deck that snaps in a cylindrical body.The metal material of easy heat conduction of this body and function of heat conduction and light weight is made.

Heat conduction body upper end is interval with conducting strip.

Electrothermal tube is coated in the heat conduction body.

Drain pan end plate face is provided with the last through hole and the lower through-hole in order to engage with a fixed mount of symmetry; Fixed mount is made up of two groups of grillage bodies, and grillage body central authorities are provided with the hole, and the upper end is provided with overhead kick portion backward, and there is the Plug Division bottom, engages with lower through-hole with the last through hole of drain pan respectively.

The overhead kick portion upper surface of fixed mount is provided with the protruding button that is upturned.

The utility model has the advantages that significantly, because the utility model is fully with natural wind free convection, with room air circulation heating, so do not have the puzzlement of noise; Because electrothermal tube is coated in the heat conduction body, the unexpected liquid of catching a cold drips and embrittlement destruction; Because cold air enters through lower port, hot-air flows out through upper port, enlarges heating surface (area) (HS, raises the efficiency, and quickens effects such as air circulation heating.

Below in conjunction with accompanying drawing structure technology feature of the present utility model is described further.But it must be noted that present embodiment for illustrative purposes only rather than to restriction of the present utility model, any according to change of the present utility model, when the function of its generation does not exceed spiritual that specification and accompanying drawing contain, all belong to scope of the present utility model.
