Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Referring to fig. 1 to 9, the invention provides a fresh air indoor unit of an air conditioner, which comprises an air conditioner shell 11 and a transmission mechanism, wherein a fresh air module 1, a heat exchange module and a driving motor 3 are arranged in the air conditioner shell 11, a driving device is connected with a cross-flow fan blade 2 of the heat exchange module, the transmission mechanism is connected between the cross-flow fan blade 2 and a fresh air centrifugal fan blade 8 of the fresh air module 1, the driving motor 3 can drive the cross-flow fan blade 2 to rotate, and the cross-flow fan blade 2 can drive the fresh air centrifugal fan blade 8 to rotate through the transmission mechanism. Aiming at the existing household split wall hanging machine with a fresh air system, the arrangement of a fresh air centrifugal fan blade 8 motor is cancelled, a cross-flow fan blade 2 of a heat exchange module is connected with a fresh air centrifugal fan blade 8 of a fresh air module 1 through a transmission mechanism, and the cross-flow fan blade 2 and the fresh air centrifugal fan blade 8 are driven to synchronously rotate by a driving motor 3 (the cross-flow fan blade 2 motor), so that the cost of a fresh air part is saved, the overall length of an air conditioner can be properly reduced, and the effect of saving the length space of the whole machine is achieved.
As an alternative implementation of the embodiment of the present invention, the transmission mechanism is a gear transmission mechanism. Referring to fig. 4 and 7, two ends of the cross-flow fan blade 2 are respectively provided with a connecting shaft 10, an output shaft of the driving motor 3 is connected with the connecting shaft 10 at one end of the cross-flow fan blade 2 to drive the cross-flow fan blade 2 to rotate, and the connecting shaft 10 at the end part of the cross-flow fan blade 2 far away from the driving motor 3 is connected with a fan blade shaft of the fresh air centrifugal fan blade 8 through a transmission mechanism.
Specifically, as shown in fig. 9, the gear transmission mechanism includes a first gear 13 and a second gear 12, a connecting shaft 10 at an end portion of the cross-flow fan blade 2 far from the driving motor 3 is connected with the first gear 13, the first gear 13 is engaged with the second gear 12, and the second gear 12 is connected with a fan blade shaft of the fresh air centrifugal fan blade 8. When the air conditioner runs, the driving motor 3 drives the cross-flow fan blade 2 to rotate through the shaft, the cross-flow fan blade 2 is meshed with the second gear 12 through the first gear 13 on the connecting shaft 10 at the other side to drive the fresh air centrifugal fan blade 8 to rotate, and an independent motor is not needed to drive the fresh air centrifugal fan blade 8.
The rotating speed of a through-flow fan blade 2 of a common household split wall-mounted unit can meet the air supply requirement generally at 600r/min, the rotating speed of a fresh air centrifugal fan blade 8 of a fresh air module 1 can meet the ventilation standard generally at about 1200r/min, and in order to reach the ventilation standard of the fresh air module 1 and not increase the diameter of the centrifugal fan blade 8, a gear is used for torque reduction and speed increase.
In practice, since the rotation speed of the household wall-mounted cross-flow fan blade 2 is generally lower than that of the fresh air centrifugal fan blade 8, when designing, preferably, the diameter of the first gear 13 is larger than that of the second gear 12, which can play a role in torque reduction and speed increase, of course, the sizes of the first gear 13 and the second gear 12 are not limited herein, and the specific ratio of the gear diameter D1 of the cross-flow fan blade 2 to the gear diameter D2 of the centrifugal fan blade 8 is designed according to the functional requirements. The two are meshed through gears with different sizes, so that the driving motor 3 of the cross-flow fan blade 2 can provide power for the fresh air centrifugal fan blade 8 and the cross-flow fan blade 2 of the air conditioner at the same time, and one motor is saved. The fresh air centrifugal fan blade 8 and the cross-flow fan blade 2 are meshed through the large gear and the small gear, so that torsion and acceleration can be reduced, and the requirements of different rotating speeds of the two fan blades are met.
The fresh air module 1 in this embodiment includes a fresh air duct, a fresh air filter screen 9 and an air inlet grille 17 which are arranged in the fresh air duct, the fresh air duct is divided into a first fresh air duct 15 and a second fresh air duct 16 by the air inlet grille 17, the first fresh air duct 15 is communicated with an air inlet 5 of the fresh air module 1, the fresh air filter screen 9 is arranged in the first fresh air duct 15, and outdoor air can enter the first fresh air duct 15 through the air inlet 5 under the action of a fresh air centrifugal fan blade 8 and can flow into the second fresh air duct 16 through the air inlet grille 17 after being filtered and dried by the fresh air filter screen 9.
As an optional implementation manner of the embodiment of the present invention, the fresh air filter screen 9 includes a filter screen body, and a drying agent is disposed on the filter screen body. After the fresh air centrifugal fan blade 8 rotates, outdoor air enters the first fresh air duct 15 of the fresh air module 1 through the air inlet 5 by suction force generated by the fan blade, the air in the first fresh air duct 15 is filtered and dried through the fresh air filter screen 9, then the air passes through the air inlet grille 17 and is sent into the second fresh air duct 16, and finally the air is sent into a room from the air outlet 6 of the fresh air module 1.
The power input of the fresh air centrifugal fan blade 8 of the traditional indoor wall-mounted air conditioner indoor unit is mostly provided by an independent motor, so that the cost is greatly increased. Meanwhile, in order to avoid the condensation problem caused by the temperature difference between the inside and the outside when the air conditioner and the fresh air component work simultaneously, the outside of the fresh air component is mostly full of sponge, and the production efficiency of the whole machine is seriously influenced. Therefore, the whole fresh air component is designed and assembled above the water pan 7, so that condensed water generated on the outer layer of the fresh air module 1 can directly flow into the water pan 7 and then is delivered to the outside from the water outlet 4 of the water pan when the air conditioner heats in winter; in summer, condensation water is generated in the fresh air part when the air conditioner heats, and the drying agent is added into the filter screen body to dry the first fresh air duct 15, so that the condensation water generated in the second fresh air duct 16 is prevented from being directly sent to a room, and the humidity in the room is prevented from being too heavy.
As an optional implementation manner of the embodiment of the present invention, a water diversion groove structure 14 is disposed at the air inlet 5 of the fresh air module 1, and condensed water generated at a matching position of the air inlet 5 and the air conditioner housing 11 can be introduced to the water pan 7 through the water diversion groove structure 14, so as to prevent the condensed water from overflowing from the air inlet 5, thereby eliminating all sponges on the fresh air component and improving the overall production efficiency.
In addition, the invention also provides a fresh air conditioner which comprises an air conditioner indoor unit and an air conditioner outdoor unit, wherein the air conditioner indoor unit is the fresh air conditioner indoor unit.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
