[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] A single-motor heater with middle air outlet comprises a case 1, a case cover 6 and a panel 2, wherein the case cover 6 is covered on the case 1, and the panel 2 is arranged in front of the case cover 6, and an air inlet 11 and a warm air hole 13 are arranged on the case cover 6, and a ventilation port is arranged on one side of the case, and a circular air cavity 15 is arranged in the case 1, and the Archimedean air duct design in the prior art is adopted, and the air cavity 15 is communicated with the air inlet 11, and a wind wheel 16 is arranged in the air cavity 15, and the wind wheel 16 is driven by a motor, and the prior art is adopted, and an air outlet 17 is connected to one side of the air cavity 15, and the ends of the air outlet 17 are respectively connected to the ventilation port through the ventilation air duct 18 and to the warm air hole 13 through the hot air channel 22;

[0028] The end of the air outlet 17 is provided with a damper mechanism which is connected to the ventilation duct 18 and the hot air duct 22 respectively. The air outlet 17 is connected to the ventilation duct 18 or the hot air duct 22 by switching the damper mechanism. The air outlet 17 is connected to the hot air duct 22 when the bathroom heater is heating, and is connected to the ventilation duct 18 when the bathroom heater is ventilating. A heater 14 is provided in the hot air duct 22. The center of the panel 2 is provided with an air outlet 3 which is connected to the warm air hole 13 and an air inlet 4 which is connected to the air inlet 11. The air inlet 4 and the air inlet 11 are arranged opposite to the wind wheel 16 to ensure smooth air intake.

[0029] The air outlet 17 is arranged in a straight line and connected to the tangent line of the air cavity 15 . The ventilation port is located on the extension line of the air outlet 17 . The hot air channel 22 is arranged perpendicular to the air outlet 17 .

[0030] The ventilation port and ventilation duct 18 are arranged in the tangent extension direction of the air cavity 15, so that the exhausted air is directly transported from the air cavity 15 to the ventilation port in a straight line and discharged, so that the air outlet is unobstructed and the ventilation efficiency is improved.

[0031] A preferred technical solution, the damper mechanism includes a rotatably arranged air guide plate 19, one end of the air guide plate 19 is rotatably installed at the connection between the inner wall of the hot air channel 22 and the inner wall of the ventilation duct 18 through a rotating shaft, the other end of the air guide plate 19 can close the hot air channel 22 and the ventilation duct 18 by rotation, the rotating shaft is fixedly connected to the air guide plate 19, and one end of the rotating shaft is connected to a rotating motor 20.

[0032] The rotating motor 20 drives the air guide plate 19 to rotate via the rotating shaft. When the air guide plate 19 abuts against the inner wall of the air outlet duct 17, the air outlet duct 17 and the hot air channel 22 are connected; when the air guide plate 19 closes the port of the hot air channel 22, the air outlet duct 17 and the ventilation duct 18 are connected.

[0033] According to a preferred technical solution, the air guide plate 19 is in a flat plate shape, the thickness of the air guide plate 19 is uniformly arranged, and when the air guide plate 19 closes the ventilation duct 18 , the end of the air guide plate 19 away from the rotating shaft is inclined toward the direction of the air cavity 15 .

[0034] In this way, when the air in the air outlet duct 17 flows toward the hot air passage 22 , the air can flow more smoothly along the inclined air guide plate 19 .

[0035] According to a preferred technical solution, when the air guide plate 19 closes the ventilation duct 18, one end of the air guide plate 19 away from the rotating shaft abuts against the inner wall of the air outlet duct 17, and the part of the air guide plate 19 away from the rotating shaft abutting against the air outlet duct 17 is arranged in a plane.

[0036] The air guide plate 19 is brought into closer contact with the air outlet duct 17 to prevent air from leaking into the ventilation duct 18 .

[0037] According to a preferred technical solution, an air guide grille 12 is provided at the warm air hole 13, and a ventilation grille 21 is provided at the ventilation port.

[0038] According to a preferred technical solution, the heater 14 is a PTC heating module.

[0039] According to a preferred technical solution, the air inlet 4 and the air outlet 3 are connected in a straight line.

[0040] According to a preferred technical solution, a circle of outer baffles 7 are protruding from the outer side of the box cover 6, and the outer baffles 7 are pressed against the inner side of the panel 2 to form an air inlet cavity 8, and the air inlet 4 is connected with the air inlet hole 11 through the air inlet cavity 8; a circle of inner baffles 9 are provided around the warm air hole 13 on the outer side of the box cover 6, and the inner baffles 9 are pressed against the inner side of the panel 2 to form an air outlet cavity 10, and the warm air hole 13 is connected with the air outlet 3 through the air outlet cavity 10.

[0041] By setting up a circle of outer baffles, the air in the ceiling interlayer can be effectively prevented from entering the air inlet cavity, so that the air can only enter from the air inlet, thereby quickly and effectively expelling the foul air in the room to the outside through the front air inlet; by setting up a circle of inner baffles, hot air can be prevented from blowing out from between the panel and the box cover into the ceiling interlayer, so that the hot air can be completely blown out from the air outlet, thereby quickly raising the indoor temperature.

[0042] According to a preferred technical solution, the size of one end of the air outlet cavity 10 connected to the warm air hole 13 is consistent with that of the warm air hole 13 , the size of one end of the air outlet cavity 10 connected to the air outlet 3 is consistent with that of the air outlet 3 , and the size of the warm air hole 13 is larger than that of the air outlet 3 .

[0043] In this way, the warm air blown out of the warm air hole 13 will gather in the air outlet cavity 10, so as to form a certain air pressure to squeeze out the air outlet 3, thereby increasing the wind speed of the warm air blown out of the air outlet 3 and making the air outlet uniform.
