In view of the above, the embodiment of the application provides an air conditioner indoor unit, which can coaxially rotate with a magnetic core rotor 14 through a through-flow fan blade 3, so that the magnetic core rotor 14 and a magnetic ring stator 13 do cutting magnetic induction lines to generate current, and power the ultraviolet sterilization component 2 to sterilize the through-flow fan blade 3.
The following describes the technical scheme of the embodiments of the present application in detail with reference to the accompanying drawings.
Example 1
Referring to fig. 1 to 3, an air conditioner indoor unit provided in an embodiment of the present application includes: the cross-flow fan blade 3 and the driving motor arranged at the axial end part of the cross-flow fan blade 3. Further, the air conditioner indoor unit in the embodiment of the application further includes:
the power generation assembly 1 is arranged at the axial end part of the cross-flow fan blade 3 and comprises a magnetic ring stator 13 and a magnetic core rotor 14; wherein, the magnetic core rotor 14 and the cross-flow fan blade 3 rotate coaxially, the magnetic ring stator 13 is fixedly arranged on an internal frame of the air conditioner indoor unit (for example, some skeletons inside a shell in the air conditioner indoor unit);
the ultraviolet sterilization component 2 is powered by the power generation component 1, and the irradiation direction of the ultraviolet sterilization component 2 is parallel to the axial direction of the cross-flow fan blade 3 and faces the central area 32 of the cross-flow fan blade 3.
In the air conditioner indoor unit provided by the embodiment of the application, when the driving motor of the cross-flow fan blade 3 rotates, the magnetic core rotor 14 is driven to rotate, and the magnetic core rotor 14 can change the strength and the direction of a magnetic field when rotating, so that a magnetic induction line is cut, electromotive force is generated, and current is generated to supply power to the ultraviolet sterilization assembly 2. And, the ultraviolet sterilization assembly 2 and the power generation assembly 1 are adjacently arranged (namely, the ultraviolet sterilization assembly 2 is also arranged at the axial end part of the through-flow fan blade 3), the irradiation direction of the ultraviolet sterilization assembly 2 is parallel to the axis of the through-flow fan blade 3 and faces the central area 32 of the through-flow fan blade 3, and the ultraviolet irradiation range of the ultraviolet sterilization assembly 2 can cover the inner cavity of the through-flow fan blade 3 to avoid bacteria breeding in the through-flow fan blade 3.
The position of the ultraviolet sterilization component 2 can be freely set according to practical situations, as long as the irradiation direction of the ultraviolet sterilization component 2 is parallel to the axis of the cross-flow fan blade 3 and can irradiate the inner cavity of the cross-flow fan blade 3. Several positions of the ultraviolet sterilization assembly 2 are described below.
Fig. 1 shows a positional relationship between the ultraviolet sterilization component 2 and the through-flow fan blade 3, in which the ultraviolet sterilization component 2 is fixed inside the axial end surface of the through-flow fan blade 3 and rotates coaxially with the through-flow fan blade 3, in which the irradiation direction of the ultraviolet sterilization component 2 is parallel to the axis of the through-flow fan blade 3, so as to sterilize the inner cavity of the through-flow fan blade 3, and part of the ultraviolet irradiation can pass through the gaps of the fan blade, and sterilize other irradiated places of the air conditioner.
In another positional relationship (not shown in the figure) between the ultraviolet sterilization component 2 and the through-flow fan blade 3, the ultraviolet sterilization component 2 is disposed outside the axial end surface of the through-flow fan blade 3 and rotates coaxially with the through-flow fan blade 3, and in this positional relationship, the end surface of the through-flow fan blade 3 may be provided with a corresponding hollow structure, which can allow the ultraviolet generated by the ultraviolet sterilization component 2 to pass through, and sterilize the inner cavity of the through-flow fan blade 3.
In the air conditioner indoor unit in the embodiment, the magnetic core rotor 14 and the magnetic ring stator 13 do cutting magnetic induction line motion to generate current so as to supply power to the ultraviolet sterilization component 2, thereby performing ultraviolet sterilization and disinfection on the inner cavity of the cross-flow fan blade 3, and compared with an ultraviolet sterilization lamp externally connected with commercial power, the wiring design of the air conditioner indoor unit can be reduced.
Example 2
In order to achieve the effect that the ultraviolet sterilization assembly 2 described in embodiment 1 can sterilize the whole through-flow fan blade 3, the embodiment of the present application further designs a corresponding structure, and on the basis of the embodiment 1, the power generation assembly 1 and the ultraviolet sterilization assembly 2 are disposed at both ends of the through-flow fan blade 3, so that the ultraviolet light fully covers the inner cavity of the through-flow fan blade 3, referring to fig. 1 and 2, the power generation assembly 1 in the embodiment of the present application has a first power generation assembly 11 and a second power generation assembly 12;
the ultraviolet sterilization assembly 2 is provided with a first sterilization assembly 21 and a second sterilization assembly 22;
the first power generation assembly 11 and the first sterilization assembly 21 are coaxially arranged at a first end 34 of the through-flow fan blade 3, the second power generation assembly 12 and the second sterilization assembly 22 are coaxially arranged at a second end 36 of the through-flow fan blade 3, and the first end 34 and the second end 36 are respectively at two axial ends of the through-flow fan blade 3.
Specifically, the power generation assemblies 1 are arranged at two ends of the through-flow fan blade 3, and the ultraviolet sterilization assembly 2 is matched to sterilize and disinfect the inner cavity of the whole through-flow fan blade 3, and the first power generation assembly 11 and the second power generation assembly 12 in the embodiment of the application are arranged at two ends of the through-flow fan blade 3 and coaxially rotate with the through-flow fan blade.
As shown in fig. 2, in the present embodiment, the driving motor 4 of the through-flow fan blade 3 is disposed at the first end 34, and the magnetic core rotor 14 of the first power generation assembly 11 is driven by the driving motor 4;
the magnetic core rotor 14 of the second power generation assembly 12 is driven by the blade shaft of the cross-flow blade 3.
In practical application, the driving motor 4 drives the cross-flow fan blade 3 to rotate, so that the air outlet function of the air conditioner is completed, and the second end of the cross-flow fan blade 3 is rotationally connected with the internal frame of the air conditioner internal unit, so that the cross-flow fan blade 3 is fixed in the air conditioner internal unit. When the driving motor 4 drives the cross-flow fan blade 3 to rotate, the first power generation assembly 11 and the second power generation assembly 12 coaxially arranged are driven to rotate, and then the first sterilization assembly 21 and the second sterilization assembly 22 are powered.
Specifically, the first power generation assembly 11, the second power generation assembly 12 and the internal structure of the air conditioner in the embodiment of the present application have the following two connection modes:
first connection relation: the magnetic core rotor 14 of the first power generation assembly 11 is coaxially arranged with the driving shaft of the driving motor, and correspondingly, the transmission relationship is as follows: the driving shaft of the driving motor 4 drives the cross-flow fan blade 3 and the magnetic core rotor of the first power generation assembly 11 to rotate at the same time. As shown in fig. 2, since the first power generation module 11 and the driving motor 4 are both disposed at the same end in the axial direction of the through-flow fan blade 3, the core rotor 14 of the first power generation module 11 may be disposed directly on the driving shaft of the driving motor 4.
Second connection relationship: the magnetic core rotor 14 of the second power generation assembly 12 is coaxially arranged with the blade shaft of the through-flow blade 3 (the magnetic core rotor is arranged on the end frame of the through-flow blade, which may be a virtual shaft or a physical shaft, depending on the actual situation). Correspondingly, the transmission relation is as follows: the driving shaft of the driving motor 4 drives the cross-flow fan blade 3 to rotate, and the cross-flow fan blade 3 drives the magnetic core rotor 14 of the second power generation assembly 12 to rotate. As shown in fig. 2, since the second power generation module 12 and the driving motor 4 are disposed at both axial ends of the through-flow fan 3, respectively, it is difficult for the driving motor 4 to directly drive the second power generation module 12, and indirect transmission is required through the end frame of the through-flow fan 3.
