Example 1:

as shown in fig. 1-4, the utility model discloses a fan heater of annular air-out, including casing 1, panel 2 and the wind wheel 3 of setting in casing 1, be provided with main motor 5 on casing 1 in wind wheel 3, main motor 5 drives wind wheel 3 and rotates, is provided with spiral case 9 on casing 1 outside wind wheel 3, and spiral case 9 is inside to form the air inlet chamber, sets up air intake 4 on the panel 2 that corresponds with wind wheel 3, is provided with air-out passageway 10 in the casing 1 of spiral case 9 side, air-out passageway 10 is communicated with spiral case 9, air-out passageway 10 includes first lateral wall 11, second lateral wall 12 and diapire 13, and first lateral wall 11 and second lateral wall 12 are the arc structure, and the upper end of first lateral wall 11 and second lateral wall 12 all docks with panel 2, and the projection of air-out passageway 10 on panel 2 is circular structure, is provided with annular air outlet 6 on panel 2 in air-out passageway 10 scope, is provided with PTC 14 at the air inlet chamber and air-out passageway 10 junction, and the air-in the air-out passageway 10 after passing through PTC 14 heating member.

The air outlet channel 10 is spiral, the end of the air outlet channel 10 is closed, and the end of the air outlet channel 10 is located above the joint of the air outlet channel 10 and the volute 9, so that the annular air outlet 6 can be ensured to be located in the range of the air outlet channel 10, and the whole annular air outlet 6 can be used for exhausting air.

The number of the wind wheels 3 in the shell 1 is two, the wind wheels 3 are arranged at two ends of the shell 1, each wind wheel 3 corresponds to one air outlet channel 10, and the two air outlet channels 10 are arranged in the middle of the shell 1 side by side.

The distance between the first side wall 11 and the second side wall 12 of the air outlet channel 10 is gradually reduced along the air flowing direction, the tail end of the air outlet channel 10 is closed, and the distance between the bottom wall 13 of the air outlet channel 10 and the panel 2 is gradually reduced along the air flowing direction.

Because the annular air outlet 6 corresponds to the air outlet channel 10, the connection part of the air inlet cavity and the air outlet channel 10 is butted with the annular air outlet 6, in order to keep the air outlet flow of each part of the annular air outlet 6 balanced as much as possible, the width and the depth of the air outlet channel 10 close to one end of the air inlet cavity are larger, and the width and the depth of the air outlet channel 10 extending to the other end are gradually reduced, namely the cavity diameter of the air outlet channel 10 is gradually reduced, and the air speed can be basically kept stable under the condition that the air volume in the air outlet channel 10 is gradually reduced.

The side wall of the shell 1 is provided with a ventilation opening 7, the ventilation opening 7 extends towards the inside of the shell 1 to form a ventilation channel 8, the ventilation channel 8 is communicated with an air inlet cavity corresponding to one of the wind wheels 3, namely the ventilation channel 8 is communicated with a volute 9, a switching gate is arranged at the joint of the ventilation channel 8 and the air inlet cavity, and the switching gate realizes the switching between the connection of the air inlet cavity and an air outlet channel 10 and the connection of the air inlet cavity and the ventilation channel 8.

The switching gate comprises a motor 16 and a gate plate 15 arranged on an output shaft of the motor 16, when the motor 16 drives the gate plate 15 to one side, the gate plate 15 seals openings communicated with the air intake cavity of the ventilation channel 8, and when the motor 16 drives the gate plate 15 to rotate to the other side, the gate plate 15 seals openings communicated with the air intake cavity of the air outlet channel 10.

The specific working process is as follows: when the wind wheel 3 starts, the air enters the air inlet cavity from the air inlet 4, enters the air outlet channel 10 from the air inlet cavity, and is output from the annular air outlet 6 along the air outlet channel 10, so that the air inlet 4 and the annular air outlet 6 are both positioned on the front surface of the panel 2, and the air inlet and the annular air outlet are arranged side by side, and the interference between the air inlet and the air outlet is reduced. The PTC heater 14 heats the air at the air outlet passage 10.

The lower ends of the first side wall 11 and the second side wall 12 of the air outlet channel 10 are connected with the bottom wall 13, the upper end of the second side wall 12 of the first side wall 11 is sealed after being matched with the panel 2, and the end part of the air outlet channel 10 is sealed, so that after the panel 2 is assembled with the casing 1, the air outlet channel 10 is sealed except for the annular air outlet 6 and the connection part of the annular air outlet 6 and the volute 9.
