Abstract

The utility model relates to an air recirculation type electric heater, which comprises a base, a shell, a heating tube, a net cover and reflector plates, and further comprises a duct, wherein the two ends of the duct are respectively communicated with air duct ports of cavities of a support plate and a bottom cover, and the duct is arranged between the reflector plates. The air recirculation type electric heater further comprises a centrifugal wind wheel which is arranged in a cavity of the base, the radial wall of the base is provided with a hot air outlet, the duct is communicated with an inner cavity of the base, a gap is arranged between the upper cover and the support plate, the radial outer side of the connecting position of the support plate and the reflector plate is provided with an upper air inlet hole, or the radial outer side of the connecting position of the bottom cover and the reflector plate is provided with a lower air inlet hole, and the lower air inlet hole is communicated with the inner cavity of the base. Because of using the structure, the air is heated by a heating tube through an air channel on a body under the action of the centrifugal wind wheel, enters the gap between a top cover and the support plate from the upper air inlet hole, enters the duct and base, and returns the cavity from the hot air outlet of the base again. The air recirculation type electric heater accelerates the indoor air to enter the body, and the temperature of the periphery bottom portions of the electric heater is rapidly increased.

Description

The air circulating type electric heater

Technical field

The utility model relates to a kind of electric heater, especially a kind of air circulating type electric heater.

Background technology

Present prior art, a kind of electric heater comprises base, shell, heat-generating pipe, guard and reflecting plate, described shell is made of the body of tubular, the loam cake that is positioned at the body upper end and the bottom of lower end, and several air ducts are arranged on the wall of body; Rounded or polygon evenly distributes and constitutes described reflecting plate by several arcs reflection plates; Arc reflection plate cooperates with heat-generating pipe; The lower end and the bottom of arc reflection plate is fixedly connected, upper end and a supporting plate are fixedly connected, and gripper shoe and body are fixedly connected, and bottom and base are fixedly connected.Existing problems are: the bottom temperature rise is slow around the electric heater.

Summary of the invention

The purpose of this utility model is: a kind of air circulating type electric heater is provided, and it can be accelerated room air effectively and enters in the body and heat, make electric heater around the bottom temperature rise fast.

The utility model is achieved in that a kind of air circulating type electric heater, comprise base, shell, heat-generating pipe, guard and reflecting plate, described shell is made of the body of tubular, the loam cake that is positioned at the body upper end and the bottom of lower end, and several air ducts are arranged on the wall of body; Rounded or polygon evenly distributes and constitutes described reflecting plate by several arcs reflection plates, and each arc reflection plate cooperates with heat-generating pipe; The lower end and the bottom of arc reflection plate is fixedly connected, upper end and a supporting plate are fixedly connected, and bottom, supporting plate and body are fixedly connected, and its special character is:

Also comprise a guide duct, the guide duct two ends respectively with supporting plate, bottom in the wind passage mouth of cavity connect; Leading the phoenix pipe is positioned in the middle of the reflecting plate;

Comprise that also one is installed in the interior centrifugal wind wheel of cavity of base, on the radial wall of base hot-blast outlet is arranged; Guide duct communicates with base intracavity;

Gapped between loam cake and the supporting plate, the radial outside of supporting plate and reflecting plate connection place has last air admission hole; Or the radial outside of bottom and reflecting plate connection place has following air admission hole; Following air admission hole communicates with the inner chamber of base.

Described air circulating type electric heater, its special character is: last air admission hole is arranged on the supporting plate, following air admission hole is arranged on the bottom.

A kind of air circulating type electric heater of the utility model, since adopt such structure, under the effect of centrifugal wind wheel, the air duct of air on body, heat by heating tube, air through heating by last air admission hole, enters the gap between top cover and the supporting plate, enter in the guide duct, enter in the base, the hot air outlet by base comes back to indoor.Move in circles like this, go into when having accelerated room air in the body, the bottom temperature rise is fast around the electric heater.
