Abstract
Description
Technical Field
[0001] The utility model mainly relates to a structure of an electric heater with multi-sided air outlet.
Background Art
[0002] An electric heater is a common electric heating device. It generates heat through built-in electric heating elements and blows hot air out through a single air outlet to heat the indoor space. However, the single-sided air outlet may cause uneven heat distribution, with a higher temperature in the area close to the heater and a relatively lower temperature in the area far from the heater, because the heat dissipation is limited to a single air outlet. The heating-up speed of the single-sided air-out electric heater may be relatively slow. In view of this, we have developed a structure of an electric heater with multi-sided air outlet.
Content of the Utility Model
[0003] To solve at least one of the above problems, the utility model proposes a new structural solution. The structure of an electric heater with multi-sided air outlet adopts the following technical solutions:
[0004] A structure of an electric heater with multi-sided air outlet includes a body and an air duct housing. The body has a cavity, and the air duct housing is installed in the cavity.
[0005] The body is provided with an air inlet and a plurality of air outlets. The air outlets are arranged in different orientations of the body, and the air inlet is communicated with the cavity.
[0006] The air duct housing has an air suction port communicated with the cavity, and the air duct housing extends a plurality of air guide ducts. A centrifugal air wheel is arranged in the air duct housing. The air flow is sucked into the cavity from the air inlet through the rotation of the centrifugal air wheel. The air flow in the cavity enters the air duct housing from the air suction port and is guided to the air outlets through the air guide ducts.
[0007] Preferably, the air outlets are arranged around the body, and each air outlet is equipped with an air outlet grille.
[0008] Preferably, the air duct housing has an air cavity, and the centrifugal air wheel is installed in the air cavity. The air suction port is located at the front end of the air duct housing, and a motor is installed at the rear end of the air duct housing. The rotating end of the motor penetrates into the air cavity and is connected with the centrifugal air wheel.
[0009] Preferably, a heating element is installed in the air guide duct.
[0010] Preferably, a wind guide housing is additionally arranged between the heating element and the air outlet.
[0011] Preferably, a decorative cover is installed at the rear end of the air duct housing to cover the motor.
[0012] The beneficial effects of the utility model compared with the background art:
[0013] In view of the fact that the existing electric heaters with single-sided air outlet may lead to uneven heat distribution and relatively slow heating speed; to solve this problem, this structure is provided with air outlets at the top and both sides of the body, so that the hot air generated by the electric heater is ejected simultaneously from the top, left, and right three directions, achieving the purpose of uniform heating and fast heating by increasing the air outlets in different directions. It has the advantages of simple structure, compact cooperation, and reasonable design; therefore, it is a product with excellent performance in both technology and economy.

[0020] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings of the specification, making the technical solutions and their beneficial effects of the present utility model clearer and more definite. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model.
[0021] The preferred embodiment provided by the present utility model: As Figures 1 to 4As shown in the figure, an electric heater fan structure with multi-faceted air outlet includes a body 1 and an air duct housing 2. The body 1 has a cavity 11, and the air duct housing 2 is installed in the cavity 11;
[0022] The body 1 is provided with an air inlet 12 and a number of air outlets 13. The air outlets 13 are arranged in different orientations of the body 1, and the air inlet 12 communicates with the cavity 11; the air outlets 13 are arranged around the body 1. Further, the air outlets 13 are provided at the top and both sides of the body 1, and each air outlet 13 is equipped with an air outlet grille 14.
[0023] The air duct housing 2 has an air suction port 21, and the air suction port 21 communicates with the cavity 11. The air duct housing 2 extends several air guide ducts 22; a centrifugal fan 23 is provided in the air duct housing 2. Airflow is sucked into the cavity 11 from the air inlet 12 by the rotation of the centrifugal fan 23. The airflow in the cavity 11 enters the air duct housing 2 from the air suction port 21 and is guided to the air outlet 13 through the air guide ducts 22.
[0024] The air duct housing 2 has an air cavity 21, and the centrifugal fan 23 is installed in the air cavity 21; the air suction port 21 is located at the front end of the air duct housing 2, and a motor 24 is installed at the rear end of the air duct housing 2. The rotating end of the motor penetrates into the air cavity 21 and is connected to the centrifugal fan 23. A decorative cover 25 is installed at the rear end of the air duct housing 2 to cover the motor, making the whole more beautiful.
[0025] The air guide duct 22 is installed with a heating element 3 to generate hot air. The heating element 3 can adopt an existing PTC heating element or an electric heating wire, preferably the PTC heating element 3. A guide air shell 4 is additionally provided between the heating element 3 and the air outlet 13. The guide air shell 4 is in a horn shape to increase the air outlet airflow.
[0026] Working process: The centrifugal fan 23 in the air duct housing 2 rotates through the motor. The rotating centrifugal fan 23 creates a negative pressure in the air cavity 21, sucking the air outside the body 1 into the cavity 11 to form an air current; the air current passes through the air inlet 12 and enters the cavity 11, and further enters the air cavity 21; the air outlets 13 of the body 1 are located at the top and both sides of the body 1, and the outlet positions of the air guide ducts 22 correspond to the positions of the air outlets 13 at the top and both sides of the body 1. At the same time, to generate a hot air current, a PTC heating element is installed at the position of the air guide duct, so that the air blown out of the body 1 is hot air. In view of the fact that the existing electric heaters with single-sided air outlet may lead to uneven heat distribution and the electric heaters may have a relatively slow heating rate, to solve this problem, this structure is provided with air outlets 13 at the top and both sides of the body 1, so that the hot air generated by the electric heater is ejected simultaneously from the top, left and right three directions, achieving the purpose of uniform heating and fast heating by increasing the air outlets 13 in different directions.
