- the sealing member 32 can be formed to have a disk shape.
- the outer diameter of the sealing member 32 can be larger than the diameter of the first air outlet 11 a , so as to improve the sealing effect of first air outlet 11 a .
- the sealing member 32 may be either integrated with the flow guiding member 31 , or connected to the guiding member 31 by screw fastening or riveting.
- the vertical sectional area of the flow guiding member 31 increases gradually along the direction from the air inlet 12 a to the first air outlet 11 a (from rear to front as shown in FIG. 8 ), which improves the air guide effect of flow guiding member 31 and prevents the air flow from being blown forward to the user who may thus feel uncomfortable.
- the flow guiding member 31 may include the mounting part 311 and the air guide part 312 which can be connected in sequential order from the rear to the front, and the mounting part 311 can slide-fit with the housing 1 .
- the mounting part 311 is formed to be cylindrical while the air guide part 312 is formed to be truncated cone shaped.
- the vertical sectional area of air guide part 312 increases gradually from the rear to the front, such that the air guide part 312 is approximately horn-shaped. Therefore, when the air flows out through the first air outlet 11 a , the air flow can be dispersed along the outer wall of the air guide part 312 around the first air outlet 11 a , which can result in a good air dispersion effect.
- the air guide part 312 can include several studs 312 a spaced in its circumferential direction on the front end, and the sealing member 32 can be bolted to the air guide part 312 .

- the first door 3 When the air conditioner indoor unit 100 is in the first breezeless mode, the first door 3 will be in the closed state, and the air can flow into the air guide channel and be discharged through multiple first micro air outlets 32 a .
- first micro air outlets 32 a can divide the air flow into several small branch air flows, and the first micro air outlets 32 a with a small diameter can slow down the air flow, so that the air can flow out slowly through multiple micro air outlets. It thus can realize the breezeless air supply effect, prevent the air from being blown directly to the users, thus causing discomfort, and make the indoor temperature distribution more uniform, which improves the user experience significantly.
- the air conditioner indoor unit 100 when the air conditioner indoor unit 100 is in the cooling mode, it can be adjusted to the first breezeless mode to prevent the cool air from being blown directly to indoor users, and the cool air can be circulated to the indoor space slowly through multiple first micro air outlets 32 a .
- the air conditioner indoor unit 100 when the air conditioner indoor unit 100 is in the heating mode, it can be adjusted to the first normal air supply mode since the air density of the warm air is relatively small and the circulation speed is relatively slow, so that the warm air can be circulated quickly into the indoor space through the first air outlet 11 a , thereby improving the heating efficiency of the air conditioner indoor unit 100 .

- The following part refers to
FIGS. 1-9 to describe the air conditionerindoor unit 100 according to embodiments of this application, which can refrigerate and heat indoor air. - As shown in
FIGS. 1 and 5 , the air conditionerindoor unit 100 according to embodiments of this application includeshousing 1,fan assembly 2, first drive mechanism 4 andfirst door 3. - Where,

Specifically, when the air conditionerindoor unit 100 works, thefan assembly 2 can be rotated to create negative pressure in the air duct flow path so that the air flow can enter the air path through theair inlet 12 a under the effect of such negative pressure, and can be discharged through thefirst air outlet 11 a and thesecond air outlet 11 b after circulating in the air path. The air flow can be discharged only through thefirst air outlet 11 a or thesecond air outlet 11 b, or be discharged through both of them. - As shown in
FIG. 5 , in a specific example of this application, thehousing 1 can include thefront panel 11 and theback plate assembly 12 which can snap-fit with each other. Theair inlet 12 a having the air-inlet grille 121 can be placed on theback plate assembly 12. Thefirst air outlet 11 a can be installed on thefront panel 11, the air duct flow path connecting thefirst air outlet 11 a to theair inlet 12 a can be installed in thehousing 1, and also can include theheat exchanger 7 which may exchange heat with the air flow in the air duct flow path.

first door 3 moving forward and backward to expose or cover thefirst air outlet 11 a. When the air conditionerindoor unit 100 works, the first drive mechanism 4 can drive thefirst door 3 forward to the set position, at which point thefirst door 3 can expose thefirst air outlet 11 a so that the air flow can be discharged through thefirst air outlet 11 a. When the air conditionerindoor unit 100 stops working, the first drive mechanism 4 can drive thefirst door 3 backward, and thefirst door 3 can cooperate with thehousing 1 to cover thefirst air outlet 11 a. - As shown in

In addition, the air flow blown out from thefirst air outlet 11 a can be distributed along the circumferential direction of thefirst access 3, the air flow from thefirst air outlet 11 a can collide with the air flow from thesecond air outlet 11 b in the indoor space, which can play the role of mixing the flows, make the indoor temperature distribution more uniform, and realize the air outlet effect without feeling the air. - Optionally, the working statuses of the
first door 3 and thesecond door 5 can be controlled separately. When the air needs to be discharged through thefirst air outlet 11 a, thefirst door 3 can be driven by the first drive mechanism 4 so as to switch thefirst door 3 to the open state, at which point thefirst air outlet 11 a will be exposed. When the air needs to be discharged through thesecond air outlet 11 b, thesecond door 5 can be driven by the second drive mechanism 6 to slide relative to thehousing 1 to expose thesecond air outlet 11 b. Of course, it can be understood that thefirst door 3 and thesecond door 5 can also move jointly, that is, thefirst door 3 and thesecond door 5 can move simultaneously, so that thefirst air outlet 11 a and thesecond air outlet 11 b can be exposed or covered simultaneously. - Therefore, through the above settings, the first drive mechanism 4 can realize the exposing and covering of the
first air outlet 11 a by controlling the forward and backward movement offirst door 3, while the second drive mechanism 6 can drive thesecond door 5 to slide relative to thehousing 1 to realize the exposing and covering ofsecond air outlet 11 b, which improves the sense of science and technology of the air conditionerindoor unit 100. In addition, the air flow blown out from thefirst air outlet 11 a can be distributed along the circumferential direction of thefirst door 3, the air flows blown out from thefirst air outlet 11 a and thesecond air outlet 11 b can be mixed in the indoor space, so that the air flows can be circulated uniformly to each corner of the indoor space, and the indoor temperature will be more even. Furthermore, thefirst door 3 can prevent the air flow from blowing directly to the users in the room to avoid discomfort, which enhances the use comfort of the air conditionerindoor unit 100 significantly. - According to embodiments of this application, the air conditioner
indoor unit 100 includes thefirst door 3 and thesecond door 5, so that the first drive mechanism 4 can realize the exposing and covering of thefirst air outlet 11 a by controlling the forward and backward movement offirst door 3, while the second drive mechanism 6 can drive thesecond door 5 to slide relative to thehousing 1 to realize the exposing and covering ofsecond air outlet 11 b, which improves the sense of science and technology of the air conditionerindoor unit 100. In addition, the air flows blown out from thefirst air outlet 11 a and thesecond air outlet 11 b can be mixed in the indoor space, so that the air flows can be circulated uniformly to each corner of the indoor space, and the indoor temperature will be more even, which enhances the use comfort of the air conditionerindoor unit 100 significantly. - As shown in
FIG. 5 , according to some embodiments of this application, thefirst door 3 can include theflow guiding member 31 and the sealing member 32.

Whenfirst door 3 is in the open state, the outer wall of theflow guiding member 31 can guide the air flow to move, and the sealing member 32 can be connected to theflow guiding member 31; when thefirst door 3 is in the closed state, the sealing member 32 can cooperate with thehousing 1 to cover thefirst air outlet 11 a; it thus can make the design offirst door 3 simpler and improve the air guide effect offirst door 3. - Specifically, when the
first door 3 is in the open state, the air outlet area offirst air outlet 11 a can be formed between theflow guiding member 31 and thehousing 1. The air flow can be blown out along the outer wall offlow guiding member 31. Theflow guiding member 31 can serve to guide air flow, which not only can reduce the circulation resistance of the air flow, improve the air outlet efficient of thefirst air outlet 11 a, but also can distribute the air properly. The air flow can be distributed around the circumferential direction offlow guiding member 31, so that the indoor temperature distribution will be more uniform. - When the
first door 3 is in the closed state, the sealing member 32 can cooperate with thehousing 1 to seal thefirst air outlet 11 a, so as to protect the air conditionerindoor unit 100 and prevent the dust and dirt from entering air conditionerindoor unit 100 through thefirst air outlet 11 a. Optionally, thefirst air outlet 11 a can be formed to have a circular shape, and the sealing member 32 can be formed to have a disk shape. The outer diameter of the sealing member 32 can be larger than the diameter of thefirst air outlet 11 a, so as to improve the sealing effect offirst air outlet 11 a. Optionally, the sealing member 32 may be either integrated with theflow guiding member 31, or connected to the guidingmember 31 by screw fastening or riveting. - As shown in
FIG. 4 andFIG. 8 , in some embodiments of this application, the vertical sectional area of theflow guiding member 31 increases gradually along the direction from theair inlet 12 a to thefirst air outlet 11 a (from rear to front as shown inFIG. 8 ), which improves the air guide effect offlow guiding member 31 and prevents the air flow from being blown forward to the user who may thus feel uncomfortable. - For example, as shown in
FIG. 8 , theflow guiding member 31 may include the mountingpart 311 and theair guide part 312 which can be connected in sequential order from the rear to the front, and the mountingpart 311 can slide-fit with thehousing 1. The mountingpart 311 is formed to be cylindrical while theair guide part 312 is formed to be truncated cone shaped. The vertical sectional area ofair guide part 312 increases gradually from the rear to the front, such that theair guide part 312 is approximately horn-shaped. Therefore, when the air flows out through thefirst air outlet 11 a, the air flow can be dispersed along the outer wall of theair guide part 312 around thefirst air outlet 11 a, which can result in a good air dispersion effect. Optionally, theair guide part 312 can includeseveral studs 312 a spaced in its circumferential direction on the front end, and the sealing member 32 can be bolted to theair guide part 312. - As shown in
FIG. 9 , in some embodiments of this application, the sealing member 32 can include multiple firstmicro air outlets 32 a distributed at intervals. Each firstmicro air outlet 32 a can run through the sealing member 32 in the thickness direction (front-rear direction as shown inFIG. 9 ); theflow guiding member 31 can include an air guide channel connected to multiple firstmicro air outlets 32 a, which thereby can realize the breezeless air outlet effect and greatly improve users' comfort level. - Specifically, the air conditioner
indoor unit 100 can have the first normal air supply mode and the first breezeless mode. When the air conditionerindoor unit 100 is in the first normal air supply mode, thefirst door 3 will be in the open state, and can be driven by the first drive mechanism 4 to move forward to the set position to expose thefirst air outlet 11 a so that a part of the air can be dispersed around theflow guiding member 31 to thefirst air outlet 11 a, while another part of the air can flow into the air guide channel and be discharged through multiple firstmicro air outlets 32 a. When the air conditionerindoor unit 100 is in the first breezeless mode, thefirst door 3 will be in the closed state, and the air can flow into the air guide channel and be discharged through multiple firstmicro air outlets 32 a. It could be understood that multiple firstmicro air outlets 32 a can divide the air flow into several small branch air flows, and the firstmicro air outlets 32 a with a small diameter can slow down the air flow, so that the air can flow out slowly through multiple micro air outlets. It thus can realize the breezeless air supply effect, prevent the air from being blown directly to the users, thus causing discomfort, and make the indoor temperature distribution more uniform, which improves the user experience significantly. - Optionally, when the air conditioner
indoor unit 100 is in the cooling mode, it can be adjusted to the first breezeless mode to prevent the cool air from being blown directly to indoor users, and the cool air can be circulated to the indoor space slowly through multiple firstmicro air outlets 32 a. When the air conditionerindoor unit 100 is in the heating mode, it can be adjusted to the first normal air supply mode since the air density of the warm air is relatively small and the circulation speed is relatively slow, so that the warm air can be circulated quickly into the indoor space through thefirst air outlet 11 a, thereby improving the heating efficiency of the air conditionerindoor unit 100. - As shown in
FIG. 6 , according to some embodiments of this application, the first drive mechanism 4 can include thefirst drive motor 45, thefirst drive gear 41 and thefirst rack 42, where thefirst drive motor 45 can be mounted in thehousing 1, thefirst drive gear 41 can be connected to and driven by thefirst drive motor 45 to rotate, thefirst rack 42 can extend along the moving direction of first door 3 (front-rear direction as shown inFIG. 6 ) and mesh with and be driven by thefirst drive gear 41, and one end of thefirst rack 42 can be connected to and drive thefirst door 3 to move. Therefore, the above settings can make the design of first drive mechanism 4 simpler; the first drive mechanism 4 drives thefirst door 3 by meshing the gear with the rack, which can make the operation offirst door 3 more stable and reduce the working noise of air conditionerindoor unit 100. - Optionally, the first drive mechanism 4 can include two one-to-one matching pairs of
first drive gear 41 andfirst rack 42, which can be spaced and connected to thefirst door 3 respectively, and which thus makes the matching structure between the first drive mechanism 4 and thefirst door 3 firmer, and the operation of thefirst door 3 more stable. Further, the first drive mechanism 4 can include afirst drive motor 45, thefirst drive motor 45 is a two-axle motor, two shafts of which rotate in the same direction and are connected to the first drive gears 41, respectively. Thus, the above settings can make the overall structure of the first drive mechanism 4 more compact and also improve the operational uniformity of the twofirst racks 42. Of course, the first drive mechanism 4 can also include twofirst drive motors 45 that can operate synchronously, and each of thedrive motors 45 is a single-axle motor and is connected to the correspondingfirst drive gear 41. - In the examples shown in
FIG. 6 andFIG. 8 , thefirst door 3 can also include thefirst connection bracket 33 and thesecond connection bracket 34 which are mounted respectively onflow guiding member 31 and distributed at intervals in the circumferential direction offlow guiding member 31. Thefirst connection bracket 33 includes the first mountinghole 331 while thesecond connection bracket 34 includes thesecond mounting hole 341. The first drive mechanism 4 includes two one-to-one matching pairs offirst drive gear 41 andfirst rack 42, as well as afirst drive motor 45, which is a two-axle motor and whose two motor shafts rotate in the same direction and are connected to one of thefirst drive gear 41 keys respectively. Eachfirst rack 42 includes afitting column 422. When the first drive mechanism 4 and thefirst door 3 are assembled together, thefitting column 422 of onefirst rack 42 can be inserted into the first mountinghole 331 of thefirst connection bracket 33, while thefitting column 422 on the otherfirst rack 42 can be inserted into thesecond mounting hole 341 on thesecond connection bracket 34. Therefore, the above settings can make the connection structure between the first drive mechanism 4 and thefirst door 3 simpler and improve the assembly efficiency of air conditionerindoor unit 100 greatly. - It should be noted that the first drive mechanism 4 is not limited to this design, as long as it can drive the
first door 3 forward and backward. For example, the first drive mechanism 4 can also be a linear motor or hydraulic drive cylinder. One end of the linear motor or hydraulic drive cylinder can be connected to thehousing 1, and the other end can be connected to thefirst door 3, which can also drive thefirst door 3 to switch flexibly between the open state and the closed state. - As shown in
FIG. 6 andFIG. 7 , in some embodiments of this application, thefirst rack 42 can include the limitinggroove 421 extending in the moving direction of the first door 3 (front-rear direction as shown inFIGS. 6-7 ), the first drive mechanism 4 also may include thestop lever 43 stretched into the limitinggroove 421, thestop lever 43 may slide-fit with the limitinggroove 421; when thefirst door 3 is in the open state, thestop lever 43 can push against one end of the limitinggroove 421 to limit thefirst door 3; so, through the above settings, thestop lever 43 can limit the position of thefirst rack 42, make thefirst door 3 move accurately to the set position and improve the operational stability of the air conditionerindoor unit 100. - Optionally, the contact sensor (not shown in the figure) can be mounted on the outer wall of the
stop lever 43, and can be connected to communicate with thefirst drive motor 45. When the first drive mechanism 4 drives thefirst door 3 to move, thefirst drive motor 45 can drive thefirst drive gear 41 to rotate, and thefirst drive gear 41 meshes with and drives thefirst rack 42 to move; when thefirst rack 42 is moving, thestop lever 43 may slide-fit with the limitinggroove 421 on thefirst rack 42. When thefirst rack 42 moves to the set position, the contact sensor on thestop lever 43 will contact with one end of the limitinggroove 421, and transfer the contact signal to thefirst drive motor 45 that will stop working after receiving such signal. Therefore, the intelligent control of the first drive mechanism 4 can be achieved through the above settings, making the operation of the first drive mechanism 4 more convenient. - As shown in
FIG. 6 , in some embodiments of this application, thefan assembly 2 may include an airoutlet duct member 26 which can be mounted facing directly with thefirst air outlet 11 a and have the mountingspace 26 a in which the first drive mechanism 4 can be mounted. In this way, the fitting structure between the first drive mechanism 4 and thefan assembly 2 would become more compact and the assembly space in the air conditionerindoor unit 100 can be reduced. - For example, as shown in
FIG. 6 , the airoutlet duct member 26 can be formed in a circular loop and includes a mountingspace 26 a internally, in which the first drive mechanism 4 can be mounted. The airoutlet duct member 26 can also include multipleair outlet louvers 261 which are mounted around the mountingspace 26 a and spaced on the circumferential direction of the airoutlet duct member 26, and can serve to guide the air flow and change the air outlet direction. The mountingspace 26 a can be either connected to the air duct flow path or isolated from the same. When the sealing member 32 is provided with the firstmicro air outlet 32 a, the mountingspace 26 a can be connected to the air duct flow path in which the air can flow into the mountingspace 26 a and be discharged through the firstmicro air outlet 32 a. When the mountingspace 26 a is isolated from the air duct flow path, the air can enter the indoor space through the air outlet area formed between theflow guiding member 31 and thehousing 1. - As shown in
FIG. 7 , in some embodiments of this application, the first drive mechanism 4 can also include therack box 44 that can be connected to the airoutlet duct member 26, and can include theguide hole 441 through which thefirst rack 42 can pass and reciprocate relative to therack box 44. Theguide hole 441 can guide thefirst rack 42 and make the operation of the same more regular and stable, thus improving the operation stability offirst door 3. - According to some embodiments of this application as shown in
FIGS. 1-2 , thehousing 1 can be provided with thesecond air outlet 11 b, while the air conditionerindoor unit 100 can be fitted with thesecond door 5 and the second drive mechanism 6. - As shown in
FIG. 1 , in some embodiments of this application, thefirst air outlet 11 a and thesecond air outlet 11 b can be distributed at intervals in the vertical direction, and thefirst air outlet 11 a is above thesecond air outlet 11 b. Thefirst door 3 is mounted at thefirst air outlet 11 a, and can be connected to the first drive mechanism 4 which drives thefirst door 3 to reciprocate to expose or cover thefirst air outlet 11 a. Thesecond door 5 is set atsecond air outlet 11 b, and can be connected to the second drive mechanism 6 which drives thesecond door 5 to reciprocate to expose or cover thesecond air outlet 11 b. - In this case, the open and closed states of the
first door 3 and thesecond door 5 can be controlled respectively. When the air conditionerindoor unit 100 is in cooling mode, the second drive mechanism 6 can drive thesecond door 5 to slide to cover thesecond air outlet 11 b, while the first drive mechanism 4 can drive thefirst door 3 to move forward to expose thefirst air outlet 11 a. It could be understood that the cool air can enter the upper half of the indoor space through thefirst air outlet 11 a since thefirst air outlet 11 a is above thesecond air outlet 11 b; the cool air can circulate slowly from top to bottom in the indoor space as the cool air density is relatively big, which not only improves the cooling effect, but also prevents the cool air from being blown to the indoor users directly through thesecond air outlet 11 b, resulting in discomfort. - When the air conditioner
indoor unit 100 is in the heating mode, the second drive mechanism 6 can drive thesecond door 5 to slide to expose thesecond air outlet 11 b, while the first drive mechanism 4 can drive thefirst door 3 to move forward to expose thefirst air outlet 11 a. Now thefirst air outlet 11 a and thesecond air outlet 11 b output air simultaneously. It could be understood that the heating efficiency of the air conditionerindoor unit 100 may be enhanced, and the warm air can circulate smoothly to the floor and warm the feet, which improves the use experience of the user when thefirst air outlet 11 a and thesecond air outlet 11 b output the air at the same time as the warm air density is relatively small and its circulation speed is relatively low. - It is noted that the
first air outlet 11 a andsecond air outlet 11 b of the air conditionerindoor unit 100 are not limited to this setting. For example, multiplefirst air outlets 11 a and multiplesecond air outlets 11 b can be set on the air conditionerindoor unit 100, which can be set according to the actual use demand. There is no specific restriction in this application. - In a specific example of this application, the
second air outlet 11 b is located above thefirst air outlet 11 a, where at thefirst air outlet 11 a there is afirst door 3 which can be connected to the first drive mechanism 4; the first drive mechanism 4 can drive thefirst door 3 to reciprocate to expose or cover thefirst air outlet 11 a. Thesecond door 5 is set at thesecond air outlet 11 b, and can be connected to the second drive mechanism 6 which drives thesecond door 5 to reciprocate to expose or cover thesecond air outlet 11 b. In this case, thesecond door 5 can expose thesecond air outlet 11 b by sliding from top to bottom, and cover thesecond air outlet 11 b by sliding from bottom to top, or cover thesecond air outlet 11 b by sliding from top to bottom and expose thesecond air outlet 11 b by sliding from bottom to top. - In some embodiments of this application, the second drive mechanism 6 can drive the
second door 5 to slide in the up-down direction, so that the air outlet area of thesecond air outlet 11 b can be adjusted conveniently. It could be understood that thesecond air outlet 11 b can be extended in the up-down direction, and the air outlet area ofsecond air outlet 11 b can be adjusted by controlling the sliding displacement ofsecond door 5 in the up-down direction, which makes the operation more convenient when the height of air conditionerindoor unit 100 is relatively large. Of course, the second drive mechanism 6 can also drive thesecond door 5 to slide along the left-right direction and along a direction that has a tilt angle with respect to the left-right direction and the up-down direction. The settings can be selected according to the actual use needs, for which there is no specific restriction in this application. - As shown in
FIG. 5 , in some embodiments of this application, the second drive mechanism 6 can include a second drive motor (not shown in the figure), asecond drive gear 61 and a second rack 62, where thesecond drive gear 61 can be connected to and driven by the second drive motor to rotate; the second rack 62 can be extended along the moving direction of second door 5 (up-down direction shown inFIG. 5 ); the second rack 62 can mesh with and be driven by thesecond drive gear 61; one end of the second rack 62 can be connected to and drive thesecond door 5 to move; in this case, the above settings can make the design of the second drive mechanism 6 simpler. Moreover, thesecond door 5 is driven by the second drive mechanism 6 through the gear-rack structure, making the operation of thesecond door 5 more stable. - Optionally, the second drive mechanism 6 can include two one-to-one matching pairs of second drive motor,
second drive gear 61 and second rack 62. Both second racks 62 are extended in the up-down direction and are spaced in the left-right direction. Both second racks 62 are connected to the inner walls ofsecond door 5. When the second drive mechanism 6 works, two second drive motors rotate synchronously and two second racks 62 drive thesecond door 5 to slide relative to thehousing 1, thereby making the operation of thesecond door 5 more stable. - In a specific example of this application, the air conditioner
indoor unit 100 can also include the door mount plate 8 on which the second drive mechanism 6 can be mounted. In this case, the second rack 62 can be mounted on the front wall of the door mount plate 8 and attached to the inner wall of thesecond door 5. The door mount plate 8 includes the slide track (not shown in the figure) while thesecond door 5 slide-fits with the slide track. Therefore, the above settings can facilitate the installation and fixation of the second drive mechanism 6, and besides, thesecond door 5 can cooperate with the slide track to reduce the sliding resistance of thesecond door 5, thus making its operation smoother and reducing the working load of the second drive motor. - It should be noted that this is not the only structural design of the second drive mechanism 6, as long as it can drive
second door 5 to slide relative to thehousing 1. For example, the second drive mechanism 6 can also be a linear motor or hydraulic drive cylinder, one end of which can be connected to thehousing 1 and the other end can be connected to thesecond door 5, which can also drive thesecond door 5 to slide relative to thehousing 1. - As shown in
FIG. 5 , in some embodiments of this application, thefan assembly 2 can include thefirst fan 22 and thesecond fan 23, where thefirst fan 22 can be set in alignment with thefirst air outlet 11 a, andsecond fan 23 can be set in alignment withsecond air outlet 11 b, so that the working states of thefirst fan 22 andsecond fan 23 can be controlled separately according to the use requirements, thereby enhancing the use flexibility of the user. - Optionally, the
first fan 22 can be an axial fan, a diagonal fan or a counter-rotating fan. Optionally, thesecond fan 23 can be an axial fan, a diagonal fan or a counter-rotating fan. - In some embodiments of this application, the
first fan 22 can be a diagonal fan, and thesecond fan 23 can be a counter-rotating fan, which improves the air supply effect of the air conditionerindoor unit 100. Understandably, the diagonal fan adopts the mode of axial air inlet and air outlet inclined at a certain angle along the axial direction for air supply. Moreover, the air outlet volume of the diagonal fan is relatively large, which not only improves the air outlet volume offirst fan 22, but also increases the air outlet angle offirst fan 22, thereby expanding the air supply range of thefirst fan 22. - This counter-rotating fan can include two wind wheels mounted on the opposite sides, whose blades are distributed in the opposite directions. When the counter-rotating fan is working, if two wind wheels rotate in opposite directions, the air supply speeds of two wind wheels can be cancelled out in the tangential directions of their rotation directions, while the air supply speeds of two wind wheels can overlap in the axial directions, which can increase the axial air supply speed of the
second fan 23, extend the air supply distance of thesecond fan 23 and enable thesecond fan 23 to supply air for long distance. If two wind wheels of the counter-rotating fan rotate in the same direction, the air supply speeds of two wind wheels may overlap in the tangential direction of their rotation directions, and the air supply speeds of two wind wheels can be cancelled out in the axial direction, so that the air can be dispersed all around thesecond fan 23 and be prevented from being blown directly to the indoor user through thesecond air outlet 11 b, thereby realizing breezeless air outlet effect and improving the use comfort of the user. - In this case, when only one wind wheel is working, the counter-rotating fan can be used to realize breezeless air outlet effect. Specifically, when one wind wheel of the counter-rotating fans is rotating, another inactive wind wheel also can rotate under the effect of the air flow. At this time, the two wind wheels will rotate in the same direction; according to the above description, the counter-rotating fan also can realize breezeless effect at this moment.
- Besides, when two wind wheels in the counter-rotating fan rotate simultaneously at low speed, they can realize the breezeless air outlet effect regardless of their rotation directions. It could be understood that the air can flow out slowly through the
first air outlet 11 a, thus realizing breezeless effect since two wind wheels in counter-rotating fan rotate at low speed, and the circulation speed of air is relatively low. - Therefore, through the above settings, the
first fan 22 can be turned on when the air supply angle needs to be increased. Thefirst fan 22 can achieve the effect of air supply in a wide range. When it is required to supply air for long distance, thesecond fan 23 can be turned on and the two wind wheels ofsecond fan 23 can be controlled to rotate in the opposite directions, thus improving the air supply distance ofsecond fan 23 greatly. When the breezeless mode is required, two wind wheels of thesecond fan 23 can be controlled to rotate in the same direction, so that thesecond fan 23 can disperse the air all around, preventing the air from being blown directly to the indoor users through thesecond air outlet 11 b. When thefirst fan 22 and thesecond fan 23 work at the same time, two air flows from thefirst air outlet 11 a and thesecond air outlet 11 b may be mixed in the indoor room so that the indoor temperature distribution will be more uniform since the air outlet angles of thefirst air outlet 11 a and thesecond air outlet 11 b are different. - It should be noted that the designs of the
first fan 22 and thesecond fan 23 are not limited herein. Thefirst fan 22 may be an axial fan, diagonal fan or counter-rotating fan, and thesecond fan 23 also may be an axial fan, diagonal fan or counter-rotating fan. It can be used in combination according to the actual use requirements, and there is no specific restriction in this application. - In the specific example shown in
FIG. 5 , the air conditionerindoor unit 100 can also include the air outlet frame component 21, which can be connected to thehousing 1. The air outlet frame component 21 has the first air duct member 24 and the second air outlet part 25 which are distributed at intervals in the up-down direction. The first air duct member 24 is set in alignment with thefirst air outlet 11 a, while the second air duct member 25 is set in alignment with thesecond air outlet 11 b. Thefirst fan 22 is installed in the first air duct member 24, while thesecond fan 23 is installed in the second air duct member 25. In this case, through the above settings, not only thefirst fan 22 and thesecond fan 23 can be installed and fixed conveniently, but also the first air duct member 24 and the second air duct member 25 can be used to guide the air flow, improving the air supply efficiency of the air conditionerindoor unit 100. - As shown in
FIG. 9 , in some embodiments of this application, thesecond door 5 can include multiple secondmicro air outlets 5 a distributed at intervals. Each secondmicro air outlet 5 a can run through thesecond door 5 in the thickness direction (front-rear direction as shown inFIG. 9 ), which thereby can realize the breezeless air outlet effect and greatly improve users' comfort level. - Specifically, the air conditioner
indoor unit 100 can have the second normal air supply mode and the second breezeless mode. When the air conditionerindoor unit 100 is in the second normal air supply mode, the second drive mechanism 6 can drive thesecond door 5 to slide relative to thehousing 1 to expose thesecond air outlet 11 b, through which the air can be discharged. When the air conditionerindoor unit 100 is in the second breezeless mode, thesecond door 5 can cooperate with thehousing 1 to cover thesecond air outlet 11 b, so that the air can be discharged through multiple secondmicro air outlets 5 a. It could be understood that multiple secondmicro air outlet 5 a can divide the air flow into several small branch air flows, and the secondmicro air outlet 5 a with small diameter can slow down the air flow, so that the air can flow out slowly through the secondmicro air outlet 5 a. It thus can realize the breezeless air supply effect, and prevent the air from being blown directly to the users, causing discomfort, which improves the user experience significantly. - Optionally, when the air conditioner
indoor unit 100 is in the cooling mode, it can be adjusted to the second breezeless mode to prevent the cool air from being blown directly to indoor users, and the cool air can be circulated to the indoor space slowly through multiple secondmicro air outlets 5 a. When the air conditionerindoor unit 100 is in the heating mode, it can be adjusted to the second normal air supply mode since the air density of the warm air is relatively small and the circulation speed is relatively slow, so that the warm air can be circulated quickly into the indoor space through thesecond air outlet 11 b, improving the heating efficiency of the air conditionerindoor unit 100. - As shown in
FIG. 9 , in some embodiments of this application, multiple thirdmicro air outlets 11 c, which are distributed at intervals along the periphery ofsecond air outlet 11 b, can be installed on thehousing 1, and each thirdmicro air outlet 11 c can run through thehousing 1 in the thickness direction (front-rear direction as shown inFIG. 9 ). Each thirdmicro air outlet 11 c can be connected to the air duct flow path, increasing air conditionerindoor unit 100's air supply efficiency and enhancing the air conditionerindoor unit 100's cooling and heating in the second breezeless mode. - For example, as shown in
FIG. 9 , thesecond air outlet 11 b can be formed into a circle and multiple secondmicro air outlets 5 a can be distributed on thesecond door 5 at intervals, placed on the opposite direction of thesecond air outlet 11 b. Multiple thirdmicro air outlets 11 c, which are located at the periphery ofsecond air outlet 11 b, are placed at intervals on thehousing 1, and are roughly formed into a circle. Therefore, through the above settings, the thirdmicro air outlets 11 c on thesecond door 5 and the thirdmicro air outlets 11 c on thehousing 1 can discharge air simultaneously, which greatly improves the air outlet efficiency of air conditionerindoor unit 100, and makes the appearance of air conditionerindoor unit 100 more artistic. - The air conditioner according to embodiments of this application includes the air conditioner
indoor unit 100 in the aforesaid embodiment of this application. - In the air conditioner according to embodiments of this application, by setting the air conditioner
indoor unit 100 mentioned above, not only the air conditioner's sense of science and technology can be improved, but also the cooling and heating effect of air conditioner can be enhanced, which promotes the user's comfort greatly, and thus enhances the market competitiveness of air conditioner. - In the description of this application, it should be understood that the orientation or position relations indicated with the terms “length”, “width”, “thickness” and “up”, “down”, “front” and “rear”, “left”, “right” and “vertical”, “inner” and “outer”, “circumferential” are based on the orientation or position relationships shown in the attached drawings, are used only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, so they shall not be construed as a restriction on this application.
