Description

Energy-saving electric fireplace warm air blowing structure

technical field

The utility model relates to an electric fireplace, in particular to an energy-saving electric fireplace warm air blowing structure.

Background technique

Traditional fireplaces generally use artificially added charcoal to burn it for heating. However, burning charcoal for heating will produce a lot of charcoal ash, so we need to clean up the charcoal ash produced frequently, and heating through charcoal is easy to pollute the environment. Traditional The existing fireplace also has shortcomings such as inconvenient movement and troublesome repairs. Therefore, various electric fireplaces have appeared on the market, which can not only achieve the heating effect but also avoid the shortcomings of traditional fireplaces. And the structure and position of the heating quartz tube are defective, not only the quartz tube is easy to be exposed, but also the blown air is uneven, which wastes energy.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides an energy-saving electric fireplace warm air blowing structure.

The technical scheme that the utility model solves its technical problem adopts is:

An energy-saving electric fireplace warm air blowing structure, including a furnace shell, an air knife and a fan, is characterized in that: the air knife is provided with a vertical air duct and a horizontal air duct connected with the vertical air duct, and the fan is located in the vertical air duct. At the air inlet of the air duct, several heating pipes are arranged in the vertical air duct, and the heating pipes are fixed on the side wall of the vertical air duct.

The transverse air passage includes a first narrow end and a first wide end, and changes from narrow to wide along the air outlet direction.

The vertical air passage includes a second narrow end and a second wide end, which change from narrow to wide along the air outlet direction, and the first narrow end communicates with the second wide end.

There are three heating pipes arranged from low to high pitch.

A support plate is provided inside the furnace shell, and a top cover is provided on the support plate, and the horizontal air duct is surrounded by the support plate and the top cover.

The furnace shell is provided with a frame plate, the frame plate is covered with a side plate, the vertical air duct is surrounded by the frame plate and the side plate, and the heating pipe is fixed on the frame plate.

The beneficial effects of the utility model are: the electric fireplace heater includes a furnace shell, an air knife and a fan, the air knife is provided with a vertical air duct and a horizontal air duct connected with the vertical air duct, and the fan is located at the entrance of the vertical air duct At the tuyere, several heat pipes are arranged in the vertical air duct, and the heat pipes are fixed on the side wall of the vertical air duct, so the heat pipes are completely covered by the vertical air duct wall and will not be exposed, which improves the safety of the product. The appearance is beautiful, and the wind blown by the fan is heated by the heat pipe in the vertical air duct, and mixed at the narrow end of the horizontal air duct due to the obstruction of the horizontal air duct wall, and then changes direction and blows out horizontally. The temperature of the hot air blown out is uniform and more Energy saving, making people feel comfortable.

Detailed ways

Referring to Fig. 1 to Fig. 7, the utility model discloses an energy-saving electric fireplace warm air blowing structure, which includes a furnace shell 1, an air knife and a fan 2, and the air knife is provided with a vertical air duct 3 and a vertical air duct 3 connected horizontal air duct 4, and the fan 2 is located at the air inlet of the vertical air duct 3, and several heating pipes 5 are arranged in the vertical air duct 3, and the heating pipes 5 are fixed on the side of the vertical air duct 3 On the wall, there are three heating tubes 5, and quartz tubes are selected, and they are arranged from low to high pitches, thereby prolonging the heating distance and preventing the wind blown by the fan 2 from reaching the heating temperature due to the short heating time.

As shown in the figure, the air knife is mainly composed of a support plate 6, an upper cover 7, a frame plate 8, and a side plate 9. On the support plate 6, the upper cover 7 of the frame plate 8 has a side plate 9, the vertical air duct 3 is surrounded by the frame plate 8 and the side plate 9, and the air inlet and the air outlet of the vertical air duct 3 are also formed by the frame plate 8 and side plates 9, the heat pipe 5 is fixed on the frame plate 8, the upper cover 7 is provided on the support plate 6, the cross air duct 4 is surrounded by the support plate 6 and the upper cover 7, and the exit of the cross air duct 4 The tuyere is surrounded by the support plate 6 and the upper cover 7, and the air inlet of the horizontal air duct 4 is arranged on the support plate 6, so through the above structure, the air inlet of the horizontal air duct 4 can be naturally connected with the outlet of the vertical air duct 3. The vents are connected.

Further, the vertical air duct 3 includes a second narrow end 10 and a second wide end 11, the air inlet of the vertical air duct 3 is located at the second narrow end 10; the air outlet of the vertical air duct 3 is located at the second wide end 11, and Along the direction of the air outlet, the wind speed is slowed down by narrowing and widening, so the residence time of the wind blown by the fan 2 in the vertical air duct 3 can be prolonged, thereby prolonging the heating time so that the wind in the vertical air duct 3 can be fully heated And reach the required heating temperature; Further, the cross air duct 4 includes a first narrow end 12 and a first wide end 13, the air inlet of the cross air duct 4 is positioned at the first narrow end 12; the air outlet of the cross air duct 4 It is located at the first wide end 13 and changes from narrow to wide along the wind outlet direction. The first narrow end 12 communicates with the second wide end 11. Through the above-mentioned structure, the wind blown out through the air outlet of the vertical air duct 3 passes through the horizontal air duct The air inlet of 4 is mixed at the narrow end of the cross air duct 4 by the blocking of the 4 walls of the cross air duct, and the hot air is also mixed at the narrow end of the cross air duct 4 while being blocked, so that the wind temperature at this place is higher. Evenly, then change the direction and blow out horizontally, and the cross air duct 4 is narrowed and widened along the direction of the wind to slow down the wind velocity, so the wind blown by the cross air duct 4 is softer and makes people feel comfortable.

An energy-saving electric fireplace warm air blowing structure provided by the embodiment of the utility model has been introduced in detail above. In this paper, specific examples are used to illustrate the principle and implementation of the utility model. The description of the above embodiment is only It is used to help understand the method of the utility model and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the utility model, there will be changes in the specific implementation and scope of application. In summary , the content of this specification should not be interpreted as a limitation of the present utility model.
