[0005] Optionally, the distance between the air guiding outlet and the rotation axis is greater than the distance between the air guiding inlet and the rotation axis, so that the air guiding frame can be switched between the first position and the second position by its own rotation.

[0037] The present invention provides an indoor air conditioner, and the indoor air conditioner adopts a new air guiding method to increase the air supply angle of the air outlet, thereby expanding the air supply range.

[0038] Please refer to Figures 1 to 2-B, in an embodiment of the indoor air conditioner of the present invention, the indoor air conditioner includes a housing 100, a damper 600, and a wind guiding frame 500. The housing 100 is provided with an air inlet 131, an air outlet 121, and an air outlet duct 301 communicating the air inlet 131 and the air outlet 121. The damper 600 is movably arranged at the air outlet 121 for opening and closing the air outlet 121. The wind guiding frame 500 has a rotation axis extending in the up and down direction ( Figure 3 and Figure 4 in which L0 is denoted as the rotation axis), the wind guiding frame 500 is rotatably arranged in the air outlet duct 301 around the rotation axis, the wind guiding frame 500 has a wind guiding cavity 510, both ends of the wind guiding cavity 510 respectively form a wind guiding inlet 511 and a wind guiding outlet 512, and the wind guiding outlet 512 can be switched between a first position and a second position, wherein: when in the first position, the wind guiding outlet 512 protrudes outwards from the air outlet 121; when in the second position, the wind guiding outlet 512 retracts to the inner side of the air outlet 121 to avoid the damper 600.

[0039] Specifically, the housing 100 includes a chassis 110, a front shell 120, a rear shell 130, and a front panel 140. Among them, the chassis 110, the front shell 120, and the rear shell 130 enclose to form a cavity, and the front panel 140 is installed in the cavity. The impeller assembly 200, the heat exchanger assembly 400, and the air duct assembly 300 for forming the air outlet duct 301 of the indoor air conditioner are all installed in the cavity. When the indoor air conditioner is working, the impeller assembly 200 drives air to enter the air outlet duct 301 of the housing 100 from the air inlet 131, after being heat exchanged by the heat exchanger assembly 400, it is blown towards the wind guiding frame 500 from the air outlet duct 301, and then is led out to the room by the wind guiding frame 500 in the wind guiding frame 500.

[0040] For the housing 100, the cross-section of the housing 100 intercepted by a plane perpendicular to the up and down direction can be circular, square, or other irregular shapes. Specifically herein, the rear end of the cross-section is arranged in a semi-circular shape, and its front end gradually shrinks forward and is arranged in a semi-elliptical shape, so that the cross-section is generally in an egg shape. This can reduce the overall volume of the indoor air conditioner, reduce the space occupied by its front end, and miniaturize the whole machine.

[0041] For the wind guiding frame 500, the wind guiding frame 500 is arranged in a long strip shape, and its rotation axis extends in the up and down direction (i.e., the length direction of the wind guiding frame 500). The wind guiding outlet 512 of the wind guiding frame 500 can be switched between the first position and the second position to meet the air supply requirements of different users. First, the uses that the wind guiding frame 500 can achieve in different positions will be introduced below. As for the switching method between different positions, it will be introduced in detail later.

[0042] Please refer to Figure 2-B, when the air guiding outlet 512 of the air guiding frame 500 is switched to the first position, the air guiding outlet 512 protrudes outward from the air outlet 121 (it can be partially or completely protruding). The air guiding outlet 512 is not easily blocked by the side edge of the air outlet 121 on the housing 100. Thus, after the air guiding frame 500 blows out the air flow from the air guiding outlet 512, it can be sent out at a wider angle and a farther distance. Its wide air supply angle can reach about 145°, which is about 65% larger than the conventional wide air supply angle, and the air supply range is significantly expanded. At the first position, by appropriately rotating the air guiding frame 500 to change the orientation of its air guiding outlet 512, the air guiding frame 500 can have multiple air supply modes such as forward air supply, left air supply, and right air supply. Among them:

[0043] Please refer to Figure 2-B , in the forward air supply mode, the air guiding frame 500 rotates to the first position so that its air guiding outlet 512 faces the front side. Since the air guiding outlet 512 protrudes from the air outlet 121, the air guiding frame 500 can concentrate the air flow and blow it forward to a farther position, effectively extending the air supply distance.

[0044] Please refer to Figure 2-C , in the left air supply mode, the air guiding frame 500 rotates to the first position so that its air guiding outlet 512 faces the left side. Since the air guiding outlet 512 still protrudes from the air outlet 121, the air guiding outlet 512 is not blocked by the left side edge of the air outlet 121, and the air guiding outlet 512 is not easily blocked by the side edge of the air outlet 121 on the housing 100, so it can supply air to a wider angle on the left side, and the left air supply distance is also relatively extended.

[0045] Please refer to Figure 2-D , in the right air supply mode, the air guiding frame 500 rotates to the first position so that its air guiding outlet 512 faces the right side. Since the air guiding outlet 512 still protrudes from the air outlet 121, the air guiding outlet 512 is not blocked by the right side edge of the air outlet 121, so it can supply air to a wider angle on the right side, and the right air supply distance is also relatively extended.

[0046] In addition, when the air guiding frame 500 continuously rotates left and right reciprocally at the first position, it can also achieve left and right air sweeping, with a larger air sweeping angle and a wider air supply range.

[0047] Please refer to Figure 2-A, when the air guiding outlet 512 of the air guiding frame 500 is switched to the second position, the air guiding outlet 512 retracts inside the air outlet 121. Compared with when the air guiding outlet 512 is in the first position, when the air guiding outlet 512 is in the second position, its air supply angle and air supply distance are relatively reduced, which can also meet the user's need for air supply in a small range and small area. Since the air guiding outlet 512 retracts inside the air outlet 121, the air damper 600 can be avoided. When the air conditioner is turned off, the air damper 600 can smoothly move along the air outlet 121 to close the air outlet 121 without interfering with the air guiding frame 500.

[0048] The technical solution of the present invention is to provide an air guiding frame 500 in the air outlet duct 301 of the air conditioner indoor unit, and the air guiding outlet 512 of the air guiding frame 500 is designed to be switchable between a first position and a second position to meet the air supply needs of different users. Among them, when the air guiding outlet 512 of the air guiding frame 500 is switched to the first position, the air guiding outlet 512 protrudes outward from the air outlet 121, and the air guiding outlet 512 is not easily blocked by the side edge of the air outlet 121 on the housing 100. Therefore, after the air guiding frame 500 blows out the air flow from the air guiding outlet 512, it can be sent out at a wider angle and a farther distance, effectively expanding the air supply range. It has been realized that the air conditioner indoor unit of the present invention can obtain an air supply angle of up to 145° relative to the conventional vertical air guiding strips, while the conventional vertical air guiding strips can only achieve left and right air guiding by swinging about 91°. It can be seen that the air supply angle of the air conditioner indoor unit of the present invention increases by about 65%, and the wide air supply angle is significantly increased.

[0049] Based on the above embodiments, there are various ways to switch the air guiding outlet 512 of the air guiding frame 500 between different positions. For example, but not limited to, the following two implementation manners:

[0050] Please refer to Figures 3 to 5 , in an embodiment, the distance between the air guiding outlet 512 and the rotation axis is greater than the distance between the air guiding inlet 511 and the rotation axis, so that the air guiding frame 500 can be switched between the first position and the second position by its own rotation.

[0051] Please refer to Figure 5 and Figure 6 , in Figure 6In the figure: S1 represents the first bisecting plane that divides the cross-section of the air guide frame 500 into two front and rear parts; S2 represents the second bisecting plane that is perpendicular to the first bisecting plane and divides the cross-section into two left and right parts; R1 represents the distance between the air guide outlet 512 and the rotation axis, and R2 represents the distance between the air guide inlet 511 and the rotation axis, that is, R1 > R2. The intersection line of the first bisecting plane and the second bisecting plane is the center line of the air guide frame 500. In the above embodiment, designing R1 > R2 is equivalent to saying that the rotation axis of the air guide frame 500 is eccentrically arranged, that is, the rotation axis deviates from the center line and is parallel to the center line. It should be noted that the first bisecting plane, the second bisecting plane, the center line, and the rotation axis are all virtual lines or planes, mainly used to explain the shape and structural characteristics of the air guide frame 500.

[0052] For the convenience of description, the part of the air guide frame 500 located between the rotation axis and the air guide outlet 512 is called the long-axis part, and the rotation radius of the long-axis part is R1; the part of the air guide frame 500 located between the rotation axis and the air guide inlet 511 is called the short-axis part, and the rotation radius of the short-axis part is R2. When the air guide frame 500 rotates to the first position, the long-axis part is rotated to the air outlet 121 and protrudes outward from the air outlet 121, while the short-axis part is rotated to the inner side of the air outlet duct 301. When the air guide frame 500 rotates to the second position, the positions of the long-axis part and the short-axis part are just swapped. However, since the short-axis part is relatively shorter than the long-axis part (i.e., R2 < R1), the short-axis part is relatively retracted inward from the second position towards the air outlet 121 by a distance of ΔR = R1 - R2. This distance of ΔR can be used to avoid the air damper 600.

[0053] For the traditional air guide frame 500, its rotation axis usually passes through its central position. Therefore, the distance between the air guide outlet 512 of the traditional air guide frame 500 and its rotation axis is equal to the distance between its air guide inlet 511 and the rotation axis. No matter how the air guide frame 500 rotates at any angle, the swapping of the positions of the air guide outlet 512 and the air guide inlet 511 does not change the actual position, and its air supply angle basically does not change, which is basically about 90°.

[0054] In another embodiment, which is different from the above-mentioned embodiment, the air conditioner indoor unit further includes a displacement driving device (not shown). The air deflector frame 500 is rotatably arranged on the displacement driving device, so as to drive the air deflector frame 500 to move back and forth through the displacement driving device, and switch the air outlet 512 of the air deflector frame 500 between a first position and a second position. That is to say, when the air conditioner indoor unit is turned on, the displacement driving device first pushes the air deflector frame 500 forward, so that the air outlet 512 of the air deflector frame 500 extends out of the air outlet 121, and then the air deflector frame 500 can be driven to rotate to adjust the orientation of the air outlet 512 and change the air supply direction.

[0055] The displacement driving device is relatively common in the mechanical field. For example, the displacement driving device includes a base, a gear and a motor. Among them, the base is used for the air deflector frame 500 to be rotatably installed. The gear is installed on the base and meshes with a rack arranged at the bottom of the housing 100. The motor is installed on the base and connected to the gear to drive the gear to roll and drive the base to move back and forth, thereby driving the air deflector frame 500 to move back and forth to switch positions. In addition, the displacement driving device can also be a base that can move back and forth, a push rod structure or a roller structure connected to the base, etc., all of which can realize driving the air deflector frame 500 to move back and forth, and will not be elaborated here one by one.

[0056] The above two ways to switch the position of the air outlet 512 of the air deflector frame 500 can be selected optionally. Considering that the displacement driving device may occupy the limited space inside the housing 100 and increase the overall weight of the air conditioner indoor unit, the first switching method mentioned above can be selected to simplify the assembly structure and reduce the assembly process. In the following embodiments, the first switching method mentioned above will be further introduced.

[0057] Please continue to refer to Figure 3 and Figure 5 In an embodiment, the air deflector 520 includes two air deflectors 520 and an end plate 530 connecting the ends of the two air deflectors 520. The two air deflectors 520 and the two end plates 530 enclose an air guiding cavity 510. An air deflector grille 540 is provided at the air outlet 512 of the air guiding cavity 510, and the air deflector grille 540 is arranged in a flat shape or a convex arc shape. As for the air inlet surface of the air inlet, it can be a convex arc shape, a concave arc shape or a flat shape.

[0058] To facilitate the installation of the air deflector 520, the air conditioner indoor unit further includes two installation components respectively arranged at the upper and lower ends of the air outlet 121. The two installation components are a first installation component 800a and a second installation component 800b respectively. The two ends of the air deflector frame 500 are respectively rotatably connected to the two installation components. The air deflector frame 500 rotates on the installation components to realize the switching of the air outlet 512 between the first position and the second position.

[0059] Specifically, the installation component is provided with a shaft hole 830 corresponding to the rotation axis of the air guide frame 500. The end plate 530 of the air guide frame 500 is provided with a rotating shaft 531 corresponding to the shaft hole 830. The air guide frame 500 is rotatably connected to the shaft hole 830 of the installation component through the rotating shaft 531. In practical applications, the air guide frame 500 can be arbitrarily rotated by 180° to 360°, and the switching of the air guide outlet 512 between the first position and the second position can be realized. However, the larger the rotation angle, the higher the design and requirements for parts such as the driving device, the assembly structure, and the wiring structure. Therefore, the rotation angle of the air guide frame 500 can be limited.

[0060] Please refer to Figure 4 、 Figure 7 and Figure 8 In an embodiment, in order to limit the rotation angle of the air guide frame 500, a first limiting post 810 and a second limiting post 820 protrude from the installation component (such as the first installation component 800a) towards the air guide frame 500, and a stop member 532 protrudes from the end face of the air guide frame 500, where: in the first position, the stop member 532 can abut against the front side of the first limiting post 810; in the second position, the stop member 532 can abut against the front side of the second limiting post 820.

[0061] During the process of rotating the air guide frame 500 to switch the air guide frame 500 from the second position to the first position, the stop member 532 separates from the first limiting post 810, and then rotates a certain angle around the rotation axis, and abuts against the second limiting post 820 after reaching the second position, so that the air guide frame 500 cannot continue to rotate.

[0062] Please refer to Figure 7 and Figure 8 Here, considering that if the first limiting post 810, the second limiting post 820 and the shaft hole 830 on the installation component are on the same straight line, then the air outlet 121 of the air guide frame 500 can reach the second position by rotating at most 180° from the first position. However, in this design method, during the process of assembling the air guide frame 500 and the installation component, the first limiting post 810 and the second limiting post 820 are likely to interfere with both sides of the air guide frame 500, and the installation difficulty is relatively high.

[0063] Therefore, in order to solve the above technical problems, the first limiting post 810 can be arranged on one side of the shaft hole 830, and at the same time, the second limiting post 820 can be arranged on the other side of the shaft hole 830 and behind the connection straight line (such as the L1 shown in Figure 8 that connects the shaft hole 830 and the first limiting post 810).

[0064] That is to say, a certain amount of margin space is reserved between the second limit column 820 and the connecting straight line, so that when the air guide frame 500 is assembled to the installation component, the air guide frame 500 can be deflected at a smaller angle to calibrate the rotating shaft 531 of the air guide frame 500 and the shaft hole 830 of the installation component, thereby greatly reducing the difficulty of installation and helping to improve assembly efficiency.

[0065] See also Figures 2-B to 2-D Based on any of the above embodiments, considering that when the air conditioner indoor unit is in working state, the air guide frame 500 protrudes outward from the air outlet 121, a windless or low-wind area is formed between the part of the air guide frame 500 protruding from the air outlet 121 and the side edge of the air outlet 121, which is easy to form a large temperature difference with the air outlet area and produce condensation water there.

[0066] Since the air guide frame 500 has air guide plates 520 located on opposite sides of the air guide cavity 510, in order to avoid the above situation, a ventilation gap 900 is formed between the air guide plates 520 and the side edges of the corresponding air outlets 121. The existence of the ventilation gap 900 allows a small portion of air to be blown out from the ventilation gap 900 to the indoor environment, so that the temperature difference between the ventilation gap 900 and other air outlet areas is similar or the same, thereby avoiding the generation of condensed water there.

[0067] However, when the ventilation gap 900 is too large, it is easy to cause air leakage, reducing the air volume of the air guide frame 500. It can be seen that the larger the ventilation gap 900 is, the better. Therefore, it is necessary to appropriately reduce the ventilation gap 900. Optionally, the outer plate surface of the air guide plate 520 is arranged in a convex arc shape from back to front toward the ventilation gap 900 to limit the width of the ventilation gap 900, thereby reducing the ventilation gap 900. In this way, the ventilation gap 900 can have wind passing through it without leaking too much air.

[0068] See also Figure 2-D , Figure 3 and Figure 4 In one embodiment, the air conditioner indoor unit also includes a louver assembly 700, the louver assembly 700 includes a plurality of louvers 710 rotatably mounted on the air guide frame 500, a connecting rod 720 connecting the plurality of louvers 710, and a motor 730 connected to the connecting rod 720, the motor 730 is used to drive the connecting rod 720 to drive the louvers 710 to swing up and down, thereby achieving up and down wind sweeping, and further adjusting the up and down air supply angle of the air guide frame 500.

[0069] Further, one end of the louver 710 close to the air guiding outlet 512 is rotatably connected to the air guiding frame 500, and the end of the louver 710 far from the air guiding outlet 512 protrudes outward from the air guiding inlet 511. The protruding part of the louver 710 can increase the swinging area of the louver 710, which is beneficial to sweeping more air volume in the air outlet duct 301 into the air guiding cavity 510 of the air guiding frame 500. When the machine is turned off, the louver 710 can be first swung upward or downward to be inclined so that the whole louver 710 is received in the air guiding cavity 510 to avoid interfering with the air door 600 to close the air outlet 121.

[0070] Further, the air guiding inlet 511 of the air guiding cavity 510 is arranged in a flared shape; correspondingly, the shape of the end of the louver 710 far from the air guiding outlet 512 is consistent with the shape of the air guiding inlet 511. This can reduce the gap between the side edges of the air guiding inlet 511 of the louver 710, increase the swinging area of the louver 710, and increase the air sweeping volume.

[0071] Please refer to Figure 2-D 、 Figure 3 and Figure 4 In an embodiment, the air door 600 is actually rotatably installed on the housing 100. In view of the installation components provided at both the upper and lower ends of the air outlet 121, in order to reduce the installation parts, the inner wall surface of the air door 600 is slidably connected to the outer peripheral edge of the installation component, so that the air door 600 can rotate around the circumference of the air guiding frame 500 to open and close the air outlet 121. The air conditioner indoor unit further includes a first driving device and a second driving device installed on the installation component. The first driving device and the second driving device are respectively connected to the air door 600 and the air guiding frame 500 to respectively drive the air door 600 and the air guiding frame 500 to work independently of each other without interference.

[0072] Here, it is also considered that since the front end of the housing 100 of the air conditioner indoor unit is arranged in a semi-elliptical shape, it is not easy for the air door 600 to rotate and move along the outer wall surface of the housing 100. Therefore, here, the air door 600 has a closed state of rotating to cover the air outlet 121 (as Figure 2-A shown), and an open state of rotating to the inner side of the air outlet duct 301 to open the air outlet 121 (as Figures 2-B to 2-D shown).

[0073] To ensure that the air door 600 can smoothly rotate into the air outlet duct 301, optionally, the air conditioner indoor unit further includes a volute 310 and a volute tongue 320. The inner surface of the volute tongue 320 is arranged in a concave arc shape facing away from the volute 310. When the air door 600 is in the open state, the air door 600 is received in the concave arc surface of the volute tongue 320.

[0074] Since in the open state of the air damper 600, the air damper 600 is received in the concave arc surface of the volute tongue 320, the exposure of the air damper 600 on the outside can be avoided, thereby preventing the overall appearance of the whole machine from being affected. Moreover, since the air damper 600 is also arc-shaped, the inner wall surface of the air damper 600 forms a wind guiding surface of the air outlet duct 301, and the air flow in the air outlet duct 301 can be guided to the air outlet 121.

[0075] The present invention also provides an air conditioner, which includes an outdoor unit and an indoor unit. The indoor unit is connected to the outdoor unit through a refrigerant pipe. For the specific structure of the indoor unit, please refer to the above embodiments. Since the wall-mounted indoor unit of the air conditioner adopts all the technical solutions of the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0076] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
