Problems solved by technology

[0003] However, the air outlet of the electric heater in the compartment faces only one direction, and the air heated by the electric heating element is blown out directly from the air outlet, resulting in too concentrated air volume, fast air outlet speed and high temperature at the air outlet of the electric heater in the compartment. Blowing directly to the passengers for a long time will cause the passengers to be very uncomfortable, and the place far away from the electric heater is colder, the cabin comfort is low, and there is no air purification device

Embodiment 1

[0037] see Figure 1-8According to an embodiment of the present invention, an electric heater for a vehicle compartment with an air-inducing air channel that can be uniformly heated includes a heating box 1, a mixing box 2, an air-inducing air channel 3 and an air outlet box 4, and the heating box 1 is fixedly embedded An air inlet pipe 5 is provided, and a fan 7 is fixedly arranged in the air inlet pipe 5 through a plurality of first connecting rods 6. A purification device is provided on the air inlet pipe 5, and the purification device includes a housing 8. The upper end of the air inlet duct 5 is fixed with a housing 8, and the housing 8 is a box structure with an upper end opening, the housing 8 is fixed with a dust filter 9, and the inner wall of the upper end of the air inlet duct 5 is fixed with a limit Position net 10, the spacer net 10 is provided with an air filter cotton 11, the air filter cotton 11 is provided with a spacer 12, and the spacer 12 is detachable, and...

Embodiment 2

[0040] see Figure 4 and 8 , for the processor 38, the processor 38 is electrically connected with a second display screen 41, and the second display screen 41 is fixed on the inner wall of the upper end of the carriage; for the dust filter 9, the dust filter 9 passes through A number of bolts 42 are detachably fixed on the upper end of the housing 8 ; for the first branch pipe 18 , the first branch pipe 18 and the third branch pipe 23 are alternately arranged on the upper end of the mixing box 2 .

[0041] Through the above scheme of the present invention, the second display screen 41 can facilitate the passengers in the compartment to know the temperature of the air outlet, and by arranging the detachable dust filter 9, it can facilitate the cleaning of the activated carbon particles 13 and the air filter cotton 11 in the housing 8. For replacement, the first branch pipe 18 and the third branch pipe 23 are alternately arranged, which can facilitate the uniform mixing of hot...

Embodiment 3

[0043] see figure 1 , for the air outlet box 4, the outer wall of the upper end of the air outlet box 4 is fixed with a mounting plate 43, and the mounting plate 43 is provided with a number of mounting holes 44; for the slow flow box 29, the slow flow box 29 A sound-insulating layer 45 is fixed on the inner wall of the air outlet box 4 , and the sound-insulating layer 45 is made of rock wool board material, and the temperature sensor 48 is fixed on the inner wall of the sound-insulating layer 45 .

[0044] Through the above solution of the present invention, the mounting plate 43 and the mounting hole 44 can facilitate fixing the air outlet box 4 on the upper wall of the compartment, and the sound insulation layer 45 can effectively reduce the noise at the air outlet box 4, thereby further increasing the comfort of passengers.

Abstract

A compartment electric heater with an induced air duct and capable of uniform heating comprises a heating box, a mixing box, the induced air duct and air outlet boxes; an air inlet pipeline is fixedlyembedded in the heating box, a draught fan is fixedly arranged in the air inlet pipeline through a plurality of first connecting rods, and a purifying device is arranged on the air inlet pipeline; the purification device comprises a shell, the shell is fixedly arranged at the upper end of the air inlet pipeline, and the shell is of a box structure with an opening in the upper end. The electric heater has the beneficial effects that air fed into the heating box and the mixing box can be filtered and adsorbed, so that the quality of air blown out of the air outlet boxes can be improved, hot airand cold air can be mixed in the mixing box, the temperature of the mixed air cannot be too high, the air outlet speed can be reduced, and the air outlet direction can be adjusted; the multiple air outlet boxes are arranged, and therefore the interior of a compartment can be evenly heated, and the comfort degree of passengers is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric heaters for carriages, in particular to an electric heater for carriages with an air-introduced air duct for uniform heating. Background technique [0002] At present, the electric heaters used for rail train cars are usually arranged on the side of the rail train cars, which usually include a housing and an electric heater arranged in the housing. The air in the casing is heated, and the heated air diffuses into the compartment from the cooling holes to increase the temperature in the compartment. [0003] However, the air outlet of the electric heater in the compartment faces only one direction, and the air heated by the electric heating element is blown out directly from the air outlet, resulting in too concentrated air volume, fast air outlet speed and high temperature at the air outlet of the electric heater in the compartment. Blowing directly to the passengers for a long time will cause t...
