When ventilation is required, the motor controls the movable baffle to close the connection between the heating duct and the guide air duct, so that the air in the guide air duct is directly discharged to the outside through the ventilation duct to realize indoor ventilation. When warm air is needed for heating, the motor controls the movable baffle to move away from the connection between the hot air duct and the guide air duct and separate the guide air duct from the ventilation duct, so that the heating duct and the guide air duct are connected, thereby allowing the air in the guide air duct to enter the heating channel, be heated by the PTC heating tube and become warm air blown out from the heater nozzle to realize warm air heating. Only one air source is needed to realize warm air heating and indoor ventilation, thereby enhancing practicality, and no two air sources of a heating fan and an exhaust fan are needed to realize warm air heating and indoor ventilation, thereby reducing costs, reducing the weight of the integrated ceiling and reducing installation difficulty. Moreover, compared with using an exhaust fan for ventilation, the exhaust fan has a stronger exhaust capacity, can quickly discharge the dirty air in the room, and maintain a better ventilation effect in the room.

DETAILED DESCRIPTION

[0021] Reference Figures 1 to 4 The embodiments of the present invention are further described.

[0022] An integrated ceiling air duct includes an installation shell 1, an exhaust fan 2, a PTC heating tube 3, a warm air nozzle 4, a ventilation pipe 5, a movable baffle 6 and a motor 7. The installation shell 1 includes a accommodating chamber 8, in which a heating air duct 101 and a guide air duct 102 that are interconnected are provided. The exhaust fan 2 is installed in the accommodating chamber 8 and corresponds to and is connected to one end of the guide air duct 102. The ventilation pipe 5 corresponds to and is connected to the other end of the guide air duct 102. The PTC heating tube 3 is installed on the heating air duct 101. The warm air nozzle 4 is installed above the PTC heating tube 3, and the warm air nozzle 4 extends out of the installation shell 1. The motor 7 is installed in the accommodating chamber 8, and the output end of the motor 7 is connected to the movable baffle 6. The movable baffle 6 is placed in the guide air duct 102 and moves in the guide air duct 102, so that the movable baffle 6 can control the connection and closing between the heating air duct 101 and the guide air duct 102.

[0023] When in use, the exhaust fan 2 is operated to draw indoor air into the receiving chamber 8 and into the guide air duct 102. During ventilation, the motor 7 controls the movable baffle 6 to move in the guide air duct 102, so that the movable baffle 6 closes the connection between the heating air duct 101 and the guide air duct 102, so that the air in the guide air duct 102 is directly discharged to the outside through the ventilation pipe 5, thereby achieving indoor ventilation.

[0024] When warm air heating is required, the motor 7 controls the movable baffle 6 to move to open the connection between the heating air duct 101 and the guide air duct 102, and isolate the guide air duct 102 from the ventilation pipe 5 to prevent the air in the guide air duct 102 from entering the ventilation pipe 5, so that the heating air duct 101 and the guide air duct 102 are connected, so that the air in the guide air duct 102 enters the heating channel. The air in the heating channel is quickly heated by the PTC heating tube 3 and becomes warm air, which is blown out from the heater nozzle 4, realizing warm air heating;

[0025] In summary, only one exhaust fan 2 is needed as an air source to realize warm air heating and indoor ventilation, which enhances practicality. It does not require two air sources, a warm air fan and a ventilation fan, to realize warm air heating and indoor ventilation, thereby reducing costs, reducing the weight of the integrated ceiling, and reducing the difficulty of installation. Compared with the ventilation efficiency of the ventilation fan, the exhaust fan 2 has a stronger exhaust capacity and can quickly discharge the indoor dirty air, so that the indoor ventilation effect is maintained better.

[0026] A guide groove 9 corresponding to the movable baffle 6 is provided on the inner wall at the bottom of the guide air duct 102, and a guide protrusion 10 slidingly connected to the guide groove 9 is installed on the movable baffle 6. The guide groove 9 is arranged on the movable path of the guide protrusion 10, so that when the motor 7 controls the movable baffle 6 to move in the guide air duct 102, the movable baffle 6 slides in the guide groove 9 through the guide protrusion 10 to reduce the friction between the movable baffle 6 and the bottom of the guide air duct 102, so that the movable baffle 6 moves smoothly. The movable baffle 6 is arc-shaped, which is convenient for guiding the air in the guide air duct 102 to flow into the heating air duct 101, and also for the air in the guide air duct 102 to flow to the ventilation pipe 5.

[0027] A brake plate 11 is installed on the side wall of the guide air duct 102, which cooperates with the bottom of the movable baffle 6 to limit the movable range of the movable baffle 6 so that the movable baffle 6 always moves in the guide air duct 102 to close or open the connection between the heating air duct 101 and the guide air duct 102. A sealing piece 12 is installed on the brake plate 11 to cooperate with the end of the movable baffle 6, so that the movable baffle 6 can move to the point where the movable baffle 6 prevents the air in the guide air duct 102 from being discharged through the ventilation pipe 5. The sealing piece 12 conflicts with the movable baffle 6 to prevent the air in the guide air duct 102 from flowing to the ventilation pipe 5 through the gap between the movable baffle 6 and the side wall of the guide air duct 102 to be discharged, resulting in a decrease in the amount of air entering the heating air duct 101, affecting the warm air heating effect.

[0028] The accommodating chamber 8 also includes an air inlet channel 13 and a fixed slot 14. The air inlet channel 13 is connected to the air inlet end of the exhaust fan 2, and the air outlet end of the exhaust fan 2 corresponds to and is connected to one end of the guide air duct 102, so that the exhaust fan 2 can draw the indoor air into the guide air duct 102 through the air inlet channel 13. The motor 7 is installed in the fixed slot 14, and a protective plate 15 is installed on the fixed slot 14. The output end of the motor 7 passes through the protective plate 15 and is rotatably connected to the protective plate 15, and the output end of the motor 7 is installed with a fixed shaft tube 16, and the movable baffle 6 is installed on the fixed shaft tube 16. The motor 7 controls the movable baffle 6 through the fixed shaft tube 16. The movable baffle 6 is installed on the fixed shaft tube 16 to facilitate the more stable connection between the movable baffle 6 and the output end of the motor 7, which is conducive to the stable movement of the movable baffle 6. The protective plate 15 prevents the air in the guide air duct 102 from entering the fixed slot 14 when a part of the air enters the ventilation pipe 5, affecting the exhaust of the ventilation pipe 5 and reducing the ventilation effect.

[0029] The heating air duct 101 is provided with a wind shield 17 connected to the warm air nozzle 4, which facilitates the air in the guide air duct 102 to guide the air when it enters the heating air duct 101, thereby facilitating the air in the guide air duct 102 to better enter the heating air duct 101, reducing the air loss in the heating air duct 101, and further avoiding the reduction of the air volume entering the heating air duct 101, which affects the warm air heating effect.

[0030] The warm air nozzle 4 includes a first mounting tube 18, and a second mounting tube 19 corresponding to the first mounting tube 18 is installed in the accommodating chamber 8. The first mounting tube 18 and the second mounting tube 19 are connected by bolts to realize the installation of the warm air nozzle 4 in the accommodating chamber 8. At the same time, it is convenient to disassemble the warm air nozzle 4 for regular cleaning to keep the warm air nozzle 4 clean.

[0031] The mounting shell 1 includes a protective cover 20, and the movable baffle 6 moves on the protective cover 20 through the guide protrusion 10. A connecting hole 21 is opened on the protective cover 20, and a connecting pipe 22 corresponding to the connecting hole 21 is installed in the accommodating chamber 8. The connecting pipe 22 is connected to the connecting hole 21 by bolts. The protective cover 20 protects the components in the accommodating chamber 8 and also hides the components in the accommodating chamber 8, thereby improving the overall aesthetics. At the same time, the protective cover 20 is easy to disassemble, which facilitates regular maintenance of the components in the accommodating chamber 8 and improves practicality.

[0032] The protective cover 20 includes a protective shield 23 corresponding to the exhaust fan 2, which is convenient for protecting the exhaust fan 2 and reducing the probability of damage to the exhaust fan 2.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
