The traditional air duct machine with single air outlet comprises a side air outlet and a lower air outlet, wherein the air inlet is usually a lower air outlet, the air outlet is arranged at the side air outlet, the air duct in the air duct machine shell is composed of a fan and an air duct component, wherein the air duct component is fixed in the shell to form a fixed air duct, so that air flow is discharged from the side air outlet after passing through the fan and the heat exchanger through the lower air outlet. Traditional air duct machine of single air-out can't satisfy the demand of user to heating process. The existing air duct machine can also realize the air inlet of the side air port and the air outlet of the lower air port by driving the air duct component to rotate through the gear train. However, when the wind pipe machine is actually assembled, the assembling master cannot accurately find the assembling positions among different gears in the gear train, so that the assembled wind pipe machine capable of reversing air supply is caused, and the air outlet direction is deviated.
As shown in connection with fig. 1-10, embodiments of the present disclosure provide an air duct machine.
The air duct machine provided by the embodiment of the present disclosure includes a connection plate 13, a sealing partition plate 2, a driving gear 42, and a driven gear 43. The connecting plate 13 is fixed in the shell 1; the sealing partition plate 2 is fixedly provided with a volute 3; the driving gear 42 is rotatably arranged on the connecting plate 13; the driven gear 43 is meshed with the driving gear 42, and the driven gear 43 penetrates through the connecting plate 13 to be fixedly connected with the sealing partition plate 2; the driving gear 42 rotates to drive the driven gear 43 and the volute 3 to rotate relative to the connecting plate 13, so that the air duct machine switches air outlet at the side air port 101 and the lower air port 102 which are perpendicular to each other. The sealing partition plate 2 comprises a convex column 24, the driven gear 43 comprises an empty frame matched with the convex column 24, and the empty frame is fixedly sleeved on the convex column 24 through the connecting plate 13. The hollow frame is an irregular hollow column 432 structure so that the driven gear 43 and the sealing partition plate 2 are precisely positioned at a certain angle and are matched and installed.
The gear in the existing air duct machine is a circular gear, and the gear installation position is a cylindrical butt joint shaft, so that the gear is widely applied, convenient to produce and convenient to install when special installation requirements on the gear are not met. However, for the air duct machine capable of reversing air supply, the rotation angle of the gear needs to be controlled, so that the circular gear needs to be improved into a gear with a specific radian, which requires an installation master to find a butt joint point between the gears in the installation process, so that the air duct machine can accurately control the air outlet direction in different air outlet modes. However, in the actual installation process, due to the requirement on the gear train site, the installation of the master is time-consuming and labor-consuming, and the installation is easy to misplace. According to the mounting structure, the butt joint shaft of the driven gear 43 is arranged to be of an irregular hollow column 432 structure, so that the mounting master only needs to rotate the driven gear 43 by a certain angle to correspond to the shape of the convex column 24 on the sealing partition plate 2, and accurate assembly can be performed. The problem of can switching over tuber pipe machine of air supply, the easy dislocation of gear installation is solved.
It will be appreciated that the irregular hollow post 432 configuration may include rectangular solid recesses, polygonal recesses, other asymmetric recesses, etc., as long as there is one and only one interface between the driven gear 43 and the sealing barrier 2. In this way, the position of the driven gear 43 relative to the sealing diaphragm 2 is always accurate during installation, regardless of the placement position of the sealing diaphragm 2.
Optionally, the ducted air conditioner further comprises a third driving device 41, the body of which is fixed on the connection plate 13, and a driving gear 42 is provided on a driving output end of the third driving device 41. The third driving device 41 is used for driving the driving gear 42 to rotate, and further driving the sector gear and the sealing partition plate 2 to rotate relative to the connecting plate 13, so that the air conditioner indoor unit switches air outlet at the side air port 101 and the lower air port 102 which are perpendicular to each other. The third driving means 41 comprises a stepper motor.
Alternatively, the driven gear 43 is a sector gear, and the sector angle θ of the sector gear ranges from: θ is more than or equal to 55 degrees and less than or equal to 75 degrees. Specifically, the sealing partition plate 2 rotates to drive the volute 3 to rotate, so that the air pipe machine is switched between a first air outlet mode and a second air outlet mode; the air pipe machine is in a first air outlet mode, and the range of an included angle alpha between the plane where the volute air outlet 31 is located and the first bottom plate is as follows: alpha is more than or equal to 10 degrees and less than or equal to 20 degrees, air is fed into the side air port 101, and air is discharged from the lower air port 102; the air pipe machine is in the second air outlet mode, and the range of an included angle beta between the plane of the volute air outlet 31 and the first bottom plate 104 is as follows: beta is more than or equal to 75 degrees and less than or equal to 85 degrees, air is taken in through the lower air port 102, and air is taken out through the side air port 101. The range of sector angle θ of the sector gear is: 55 be less than or equal to θ is less than or equal to 75, the spiral case 3 of this application only need carry out the small-angle rotation, just can switch the air-out between two perpendicular wind gap, and need not to reserve the rotatory space of dodging of spiral case 3, makes tuber pipe machine carry out wind gap switching air-out in complete machine thickness 200mm space. The air duct machine of the application has small space occupation ratio, and further solves the problem that the air duct machine with reversing air outlet cannot be installed due to too small ceiling space. Preferably, the sector angle theta of the sector gear is 65 degrees, so that the air pipe machine has better air outlet performance in a space with the thickness of 200mm of the whole machine.
It will be appreciated that the rotation of the sector gear can rotate the sealing diaphragm 2 and the volute 3. The volute 3 rotates to enable the air pipe machine to be switched between a first air outlet mode and a second air outlet mode. Wherein, the air pipe machine is in a first air outlet mode, air is taken in by the side air port 101 and is discharged by the lower air port 102; in the second air outlet mode, the air is taken in from the lower air port 102 and is discharged from the side air port 101. And when the air pipe machine runs under the heating working condition, the air pipe machine is in a first air outlet mode. The air outlet direction of the air pipe machine is downward air outlet, hot air is lighter and is easy to float at the top of a room, and hot air can be sent to a human body area in an air outlet mode of downward air outlet, so that the comfort of the space of the area where a user is located is better. And when the air pipe machine operates under the refrigeration working condition, the air pipe machine is in a second air outlet mode. The air outlet direction of the air pipe machine is lateral air outlet, and the cold air drops from top to bottom during refrigeration, so that the refrigeration and the air supply are more uniform.
Optionally, the driven gear 43 further includes a gear body, gear teeth 434, and a cam 435. The gear body is in a sector shape, the gear body comprises a first side face and a second side face which are opposite to each other, the hollow frame penetrates through the gear body to form an irregular convex hull 433 on the first surface, an irregular hollow column 432 is formed on the second surface, and the hollow column 432 is fixedly connected with the sealing partition plate 2; the gear teeth 434 are positioned at the head of the gear body, the gear teeth 434 are meshed with the driving gear 42, and the circle center of the reference circle of the gear teeth 434 is positioned on the hollow column 432; the cam 435 is located at the rear of the gear body. The hollow column 432 on the second surface is used for limiting butt joint with the sealing partition plate 2, and the convex hull 433 on the first surface plays a role in prompting an installer. When the driven gear 43 is mounted, the driven gear 43 can be accurately abutted and mounted on the sealing partition plate 2 only by rotating the driven gear 43 by a certain angle to enable the shape of the convex hull 433 to be matched with the shape of the convex column 24.
Optionally, the gear teeth 434 have a first end and a second end respectively, and the driving gear 42 is meshed with the first end, so that the air pipe machine operates in the first air outlet mode; the driving gear 42 is engaged with the second end portion, and the air duct machine operates in the second air outlet mode. Compared with the traditional air duct machine capable of reversing air supply, the air duct machine has the advantages that elements such as micro-control switches are not required to be additionally arranged, different air outlet modes can be switched, and the cost of the elements and the inner space of the air duct machine are saved. The provision of the cam 435 enables a larger space for the connection plate 13 to be provided for mounting or for avoiding other components. The hollow post 432 is disposed on the pitch circle center of the gear teeth 434 to enable the sealing diaphragm 2 and the scroll 3 to axially rotate about a line where the center of the circle is located.
Optionally, the thickness of the gear teeth 434 and the cam 435 are greater than the thickness of the gear body, so that the first side surface and the outer periphery of the gear body form a first groove, and the second side surface and the outer periphery of the gear body form a second groove; wherein the convex hull 433 is located in the first recess and the hollow post 432 is located in the second recess.
