Description
Technical Field
The utility model relates to an electric heater.
Background
When the existing electric heater is used, when a user is close to the electric heater, the low gear can be opened, but when the user is far away from the electric heater, the wind power weakening temperature is reduced when the low gear warm air reaches the periphery of the body of the user, and the heating requirement of the user cannot be met. Therefore, the electric heater has to be opened to a high level, so that the hot air can reach a longer distance and keep a higher temperature, correspondingly, the cost of consumed electric power is correspondingly increased due to the use of higher power, the hot air output by the electric heater can have uneven conditions, and people can feel uncomfortable due to high and low air supply temperature.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a wind channel structure of electric heater, this wind channel structure simple structure, the air-out is even, the air supply distance is far away, helps improving the inhomogeneous and not far away situation of air-out distance of air-out that people appear when using the electric heater.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an electric heater is provided with a shell and a heating element, wherein the shell is provided with an air inlet and an air outlet, an air duct is formed between the air inlet and the air outlet in the shell, the heating element is assembled in the air duct and used for radiation heat transfer and convection heat transfer between the air inlet and the air outlet and the outside, the section of the air outlet is smaller than or equal to any section of the air duct on any section in the flowing direction perpendicular to air flow, and the section of the air outlet is smaller than that of the air inlet.
The utility model has the advantages of because on the arbitrary cross-section in the circulation direction of perpendicular to air current, the cross-section of air outlet is less than or equal to the arbitrary cross-section in wind channel, and the cross-section of air outlet is less than the cross-section of air intake. The wind channel cross section that is close to the air outlet has the part that reduces promptly, and the air becomes hot-blast under heating element's effect, and according to the fluid that density is little can upwards flow principle under the effect of buoyancy, so the warm braw can flow to the top automatically, when hot-blast air outlet through the wind channel, receives the influence that the wind channel reduces, and speed can rise, therefore can effectively improve electric heater transport distance and keep the warm braw temperature.
The utility model discloses the accessible improves with following scheme:
the shell comprises preceding baffle, back baffle, left baffle, right baffle, air intake panel and air outlet panel, and the air outlet panel is in the top of air intake panel, and the air intake setting is on the air intake panel.
Grid nets are arranged at the corresponding air inlet and air outlet of the air inlet panel and the air outlet panel, the grid nets are respectively provided with air inlet holes and air outlet holes, the air outlet holes are of narrow slit structures, and air deflectors are arranged above and below each row of air outlet holes.
The air outlet sets up on the air outlet panel, and the air outlet panel forms the slope contained angle with the central axis at air current circulation direction place.
The air guide plates are of strip structures and are arranged on one surface far away from the air inlet panel, one end of each air guide plate is fixedly connected with the air outlet panel, and the other end of each air guide plate is suspended in the air; the extending direction of one end of the air deflector close to the air outlet panel and the extending direction of one end far away from the air outlet panel are consistent with the extending direction of air flow circulation. The uniform warm air output by the electric heater is facilitated.
