Description

Air conditioner indoor unit and air conditioner

[0001] This disclosure is based on and claims priority to CN application No. 2024102190771, filed on February 28, 2024, and application No. 2024102196481, filed on February 28, 2024. The disclosure contents of the CN applications are hereby incorporated into this application as a whole. Technical Field

[0002] The present disclosure relates to the technical field of air conditioning, and in particular to an air-conditioning indoor unit and an air conditioner. Background Art

[0003] Some related technologies use horizontal sideways air delivery in indoor air conditioners. In heating mode, heated air is blown out horizontally. However, due to its low density, hot air rises, and people's heat needs are at or below 1.6 meters. This makes it difficult for hot air to reach human activity areas, resulting in poor heating performance. Other related technologies use downward air delivery, and in cooling mode, cold air blows directly onto the human body, resulting in poor comfort. Therefore, there is a need for an indoor air conditioner with adjustable air delivery direction.

[0078] 3 a , 3 b , 4 a and 4 b , in some embodiments, the air conditioner indoor unit includes a housing 1 , a volute 2 , a movable part 3 and a baffle 4 .

[0079] The housing 1 includes a first air return port 11 and a second air return port 12 .

[0080] The volute 2 is disposed in the housing 1 , and includes a first air outlet 21 and a second air outlet 22 (see FIG. 5 and FIG. 17 ).

[0081] The movable member 3 is disposed in the volute 2. The movable member 3 is configured to move to shield the first air outlet 21 and avoid the second air outlet 22 (see FIG4a), or avoid the first air outlet 21 and shield the second air outlet 22 (see FIG3a).

[0082] 6 , 21 , and 22 , the baffle 4 is disposed inside the housing 1 and outside the volute 2. The baffle 4 is configured to move to shield the first return air inlet 11 (see FIG3 b ) and avoid the second return air inlet 12, or to avoid the first return air inlet 11 and shield the second return air inlet 12 (see FIG4 b ).

[0083] In the above embodiment, the movable part 3 is configured to move to cover the first air outlet 21 and avoid the second air outlet 22, or avoid the first air outlet 21 and cover the second air outlet 22, so that the first air outlet 21 and the second air outlet 22 can be selected to be in a working state; the baffle 4 is configured to move to cover the first return air outlet 11 and avoid the second return air outlet 12, or avoid the first return air outlet 11 and cover the second return air outlet 12, so that the first return air outlet 11 and the second return air outlet 12 can be selected to be in a working state. Therefore, the return air outlet and the air outlet can be selected according to needs, and the return air and air outlet positions can be changed. Downward return air and sideward air outlet can be realized, and cold air can be blown horizontally to avoid the discomfort caused by direct blowing of cold air; sideward return air and downward air outlet can also be realized to realize downward blowing of hot air, thereby improving the heating effect.

[0084] In some embodiments, the baffle 4 is connected to the movable member 3 .

[0085] In the above embodiment, the baffle 4 is connected to the movable part 3. The position of the movable part 3 can be adjusted while adjusting the position of the baffle 4, or the position of the movable part 3 can be adjusted while adjusting the position of the baffle 4. The return air and outlet air positions can be adjusted simultaneously, and the adjustment method is convenient and easy to operate.

[0086] In the above embodiment, when the tuyere is not blocked, the tuyere is in an operating state, and when the tuyere is blocked, the tuyere is in a non-operating state.

[0087] In some embodiments, the movable member 3 and the baffle 4 are configured to move to form at least two working states:

[0088] 3a and 3b , the movable member 3 shields the second air outlet 22 , and the baffle 4 shields the second return air outlet 12 , so that the airflow enters the volute 2 through the first return air outlet 11 and flows out from the first air outlet 21 ;

[0089] 4 a and 4 b , the movable member 3 blocks the first air outlet 21 , and the baffle 4 blocks the first return air outlet 11 , so that the air flows into the volute 2 through the second return air outlet 12 and flows out from the second air outlet 22 .

[0090] In the above embodiment, the movable part 3 can be adjusted to cover the second air outlet 22, and the baffle 4 can be adjusted to cover the second return air outlet 12, so that the air flow enters the volute 2 through the first return air outlet 11 and flows out from the first air outlet 21; and the movable part 3 can be adjusted to cover the first air outlet 21, and the baffle 4 can be adjusted to cover the first return air outlet 11, so that the air flow enters the volute 2 through the second return air outlet 12 and flows out from the second air outlet 22, which can conveniently and quickly realize downward return air and side air outlet, realize flat blowing of cold air, and avoid the discomfort caused by direct blowing of cold air; or realize side return air and downward air outlet, realize downward blowing of hot air, and improve the heating effect.

[0091] In some embodiments, the air conditioner indoor unit further includes a fan blade 7, which is disposed in the volute 2. Optionally, the fan blade 7 and the volute 2 form a centrifugal fan.

[0092] In some embodiments, the air conditioner indoor unit further includes a heat exchanger 8 , which is disposed in the housing 1 .

[0093] In some embodiments, the movable member 3 is configured to rotate relative to the housing 1 to shield the first air outlet 21 or the second air outlet 22. The baffle 4 is configured to rotate relative to the housing 1 to shield the first return air outlet 11 or the second return air outlet 12. Of course, the movable member 3 and the baffle 4 are not limited to rotating to change position to achieve shielding or avoiding the air outlet.

[0094] In some embodiments, the air conditioner indoor unit further includes a power mechanism 5 , which is drivingly connected to the baffle 4 or the movable part 3 .

[0095] In the above embodiment, the power mechanism 5 can be connected to the baffle 4 or to the movable member 3 .

[0096] In some embodiments, the movable member 3 is connected to the baffle 4. Since the movable member 3 and the baffle 4 are connected, the power mechanism 5 can simultaneously drive the baffle 4 and the movable member 3 to move regardless of whether it is connected to the baffle 4 or the movable member 3, and the adjustment method is convenient.

[0097] 3 a and 4 a , in some embodiments, the movable member 3 can form a complete volute-shaped structure with a portion of the volute 2 when shielding the first air outlet 21 or shielding the second air outlet 22 .

[0098] In the above embodiment, the movable part 3 can form a complete volute-like structure with part of the volute 2 while covering the first air outlet 21, so that the second air outlet 22 is in a working state; and can also form a complete volute-like structure with part of the volute 2 while covering the second air outlet 22, so that the first air outlet 21 is in a working state. Therefore, the air outlet position can be adjusted without affecting the volute-like structure, thereby achieving normal return air and air outlet.

[0099] 3a, 4a and 11, in some embodiments, the movable part 3 includes a first arc segment 33 and a second arc segment 34. When the movable part 3 covers the first air outlet 21 or covers the second air outlet 22, the first arc segment 33 and a part of the volute 2 form a volute cavity of a volute-like structure, and the second arc segment 34 and a part of the volute 2 form a volute tongue of a volute-like structure.

[0100] In the above embodiment, the volute structure includes a volute cavity and a volute tongue, and the volute cavity is provided with a fan blade 7. The volute tongue is located at the outlet of the volute structure.

[0101] In the above embodiment, the movable part 3 includes a first arc segment 33 and a second arc segment 34. The first arc segment 33 and a part of the volute 2 form a volute cavity of a volute-like structure, and the second arc segment 34 and a part of the volute 2 form a volute tongue of a volute-like structure. Therefore, the movable part 3 can be assembled with a part of the volute 2 to form a complete volute-like structure or a nearly complete volute-like structure without affecting the air output.

[0102] 11 , the movable member 3 is projected on a cross section perpendicular to the central axis of the volute 2 . On the projection surface, the movable member 3 includes at least a first arc segment 33 and a second arc segment 34 , and the protrusion directions of the first arc segment 33 and the second arc segment 34 are different.

[0103] In the disclosed embodiment, the central axis of the volute 2 coincides with the rotation axis of the fan blade 7 .

[0104] In some embodiments, the baffle 4 cooperates with the shell 1 to separate the outlet positive pressure air flow channel and the return air negative pressure air flow channel from the outside of the volute 2 to prevent the outlet air flow from flowing back to the return air outlet of the unit.

[0105] The movable member 3 and baffle 4 can simultaneously change the direction of the airflow and return air through a single transformation. This, combined with the rotation of the fan blades 7, allows for downward air intake and lateral airflow (see Figures 3a and 3b), or lateral air intake and downward airflow (see Figures 4a and 4b). The external appearance of the air conditioner indoor unit is: downward return air and lateral airflow (see Figure 1) and lateral return air and downward airflow (see Figure 2). In conjunction with the heat exchanger 8's cold / hot conversion, cold air can be discharged to the side and hot air can be discharged to the bottom.

[0106] In some embodiments, the baffle 4 is configured as an arc-shaped plate, which facilitates the baffle 4 to rotate within the housing 1 and avoids interference with other components.

[0107] 3 b and 4 b , in some embodiments, the housing 1 is provided with mating portions 13 , 14 , 15 , which abut against the baffle 4 to shield the first return air outlet 11 or the second return air outlet 12 .

[0108] In the above embodiment, the baffle 4 cooperates with the matching parts 13, 14, and 15 on the shell 1 to separate the outlet positive pressure air flow channel and the return air negative pressure air flow channel from the outside of the volute 2, preventing the outlet air flow from flowing back to the return air outlet of the unit.

[0109] 3 b and 4 b , in some embodiments, the mating portions 13 , 14 , 15 include a first mating portion 13 , a second mating portion 14 and a third mating portion 15 .

[0110] Referring to Figure 3b, when baffle 4 blocks second return air inlet 12, its two ends in the rotational direction abut against first and second mating portions 13, 14, respectively. Baffle 4 cooperates with first and second mating portions 13, 14 to block second return air inlet 12, leaving first return air inlet 11 at the location of suction side 101. Airflow drawn in by first return air inlet 11 enters volute 2.

[0111] Referring to Figure 4b, when baffle 4 blocks first return air inlet 11, its two ends in the rotational direction abut against second and third mating portions 14, 15, respectively. Baffle 4, in conjunction with second and third mating portions 14, 15, blocks first return air inlet 11, allowing the location of second return air inlet 12 to form suction side 101. Airflow drawn in by second return air inlet 12 enters volute 2.

[0112] In some embodiments, the matching portions 13 , 14 , 15 are provided on the inner wall of the housing 1 and extend toward the interior of the housing 1 to contact and match with the baffle 4 to shield the first return air outlet 11 or the second return air outlet 12 .

[0113] In the above embodiment, the second matching portion 14 abuts and cooperates with the baffle 4 when the baffle 4 covers the first return air outlet 11 or the second return air outlet 12; however, the position where the second matching portion 14 abuts and cooperates with the baffle 4 when the baffle 4 covers the first return air outlet 11 or the second return air outlet 12 is different.

[0114] In some embodiments, referring to Figure 12, the baffle 4 includes an arc-shaped portion 43 and a bent portion 44. The curvature of the arc-shaped portion 43 is adapted to the curvature inside the shell 1. The bent portion 44 connects the arc-shaped portion 43 and is bent obliquely toward the outside of the shell 1. The bent portion 44 is located between the second mating portion 14 and the third mating portion 15 (refer to Figure 3b and Figure 4b).

[0115] 3 b , when the baffle 4 covers the second air return port 12 , the bent portion 44 abuts against the second matching portion 14 .

[0116] 4 b , when the baffle 4 shields the first air return port 11 , the bent portion 44 abuts against the third matching portion 15 .

[0117] 10 , in some embodiments, a central axis of the first air outlet 21 extending in the air outlet direction intersects a central axis of the second air outlet 22 extending in the air outlet direction.

[0118] In the above embodiment, the central axis of the first air outlet 21 extending along the air outlet direction intersects with the central axis of the second air outlet 22 extending along the air outlet direction, which can make the air outlet directions of the first air outlet 21 and the second air outlet 22 different. Therefore, the air outlet direction can be selected according to needs, and the applicability is good.

[0156] Each movable part 3 and each baffle 4 can be adjusted individually, and the adjustment method is flexible.

[0157] 10 , the first angle a1 has an angle range of [70°, 160°].

[0158] The first angle a1 is the angle formed by the first line L1 and the second line L2. The volute 2 is projected on a cross section perpendicular to the central axis of the volute 2. From the projection diagram, the first line L1 is a line connecting the midpoint M1 of the first air outlet 21 and the center C of the volute 2, and the second line L2 is a line passing through the midpoint M2 of the second air outlet 22 and the center C of the volute 2.

[0159] When the first angle a1 is too small, less than 70 degrees, assuming the horizontal air supply direction remains unchanged, the downward airflow will be tilted upward, and the hot air density is large, so the heating airflow floats upward, resulting in poor heating effect of the entire room.

[0160] When the first angle a1 is too large, greater than 160 degrees, assuming that the direction of the horizontal air supply airflow remains unchanged, the downward airflow will be converted into air discharge to the side and rear, resulting in the unit being too large and the airflow direction not being the expected downward airflow direction; if the airflow is further diverted to downward air supply through the air duct, not only will the unit size increase, but unnecessary airflow diversion losses will also be caused.

[0161] Therefore, in the above embodiment, the angle range of the first angle a1 is [70°, 160°], which can enable the first air outlet 21 and the second air outlet 22 to respectively realize lateral air outlet and downward air outlet, taking into account both downward air outlet and side air outlet, and realizing horizontal cooling and downward heating; and on the basis of satisfying downward air outlet and side air outlet, it can cooperate with the movable part 3 to form a complete or nearly complete volute-shaped structure, thereby not causing attenuation of air outlet volume and increase of noise.

[0162] In the disclosed embodiment, the extension direction of the central axis of the volute 2 is consistent with the extension direction of the rotation axis of the fan blade 7 in the volute 2.

[0163] In some embodiments, the double air outlet angle of the volute 2 can also be defined as: the volute 2 is projected on a cross section perpendicular to the central axis of the volute 2. In the projection diagram, the angle formed by the midpoint of the line connecting the far ends of the two air outlets of the unit and the line connecting the center of rotation of the fan blade is the first angle a1.

[0164] Preferably, 100°≤a1≤140°.

[0165] 11 , in some embodiments, the second angle a2 has an angle range of [190°, 280°]. Alternatively, the second angle a2 has an angle range of [200°, 280°]. Alternatively, the second angle a2 has an angle range of [190°, 270°].

[0166] The second angle a2 is the angle formed by the third line L3 and the fourth line L4. The volute 2 and the movable part 3 are projected on a cross section perpendicular to the central axis of the volute 2. From the projection diagram, the third line L3 is the line connecting the first end 31 of the movable part 3 in the rotation direction and the center C of the volute 2. The fourth line L4 is the line connecting the second end 32 of the movable part 3 in the rotation direction and the center C of the volute 2. The first end 31 and the second end 32 are the two ends on the movable part 3 that are farthest apart in the rotation direction.

[0167] In the above embodiment, the second angle a2 can also be defined as: the angle formed by the line connecting the two ends of the profile of the movable part 3 and the rotation center of the fan blade.

[0168] Because it rotates as a whole, in principle a2 satisfies a2+a1=360 degrees. In fact, a2 also needs a length for overlapping and sealing with the fixed volute, so a2=360-a1+overlap sealing angle, and the preferred range is probably [190°, 280°].

[0169] In the above embodiment, the movable part 3 is projected onto a cross section perpendicular to the central axis of the volute 2. From the projection, if the profile of the movable part 3 is too short, it will not form a complete volute-like structure with parts of the volute 2. If the profile of the movable part 3 is too long, it will interfere with the volute 2. To avoid interference between the movable part 3 and the volute 2, the thickness of the entire machine needs to be increased, and the diameter of the fan blades needs to be reduced, resulting in a decrease in air volume and an increase in noise. Therefore, the angular range of the second angle a2 is: [190°, 280°], which can both enable the movable part 3 to rotate smoothly and form a complete volute-like structure with parts of the volute 2, while preventing interference with air volume and the generation of high noise.

[0170] Preferably, 210°≤a2≤260°. Preferably, 220°≤a2≤260°.

[0171] 12 , in some embodiments, the third angle a3 has an angle range of [80°, 180°].

[0172] The third angle a3 is the angle formed by the fifth line L5 and the sixth line L6. The volute 2 and the baffle 4 are projected on a cross section perpendicular to the central axis of the volute 2. From the projection diagram, the fifth line L5 is the line connecting the third end 41 of the baffle 4 in the rotation direction and the center C of the volute 2. The sixth line L6 is the line connecting the fourth end 42 of the baffle 4 in the rotation direction and the center C of the volute 2. The third end 41 and the fourth end 42 are the two ends on the baffle 4 that are farthest apart in the rotation direction.

[0173] Similarly, because it is an overall rotation, a3 = a1 + overlapping sealing angle, so the approximate preferred range is [80°, 180°].

[0174] In some embodiments, the third angle a3 may also be defined as the angle formed by the line connecting the two ends of the baffle 4 and the rotation center of the blade when the baffle 4 is projected on a section perpendicular to the rotation axis of the blade 7 .

[0175] Preferably, 90°≤a3≤140°.

[0176] In the above embodiment, since the baffle 4 rotates together with the movable member 3 , the curvature of the baffle 4 needs to be adapted to the curvature of the movable member 3 .

[0177] In the above embodiment, the third angle a3 ranges from 80° to 180°. If the third angle a3 is too large, the baffle 4 will interfere with the housing 1, affecting the overall thickness of the device. If the third angle a3 is too small, when the baffle 4 and the mating portion shield the return air outlet, the mating portion needs to extend further into the housing 1, thereby reducing the flow area of ​​the air duct within the housing 1, increasing return air resistance, and increasing noise.

[0178] 13 , in some embodiments, projections of the baffle 4 and the movable member 3 on a cross section perpendicular to the central axis L of the volute 2 have overlapping sections 6 .

[0179] In the above embodiment, the projections of the baffle 4 and the movable part 3 on the cross section perpendicular to the central axis L of the volute 2 have overlapping segments 6. On the basis of the above-mentioned definition of the baffle 4 and the movable part 3 profile lines, the relative positions of the baffle 4 and the volute 2 are further defined, which can prevent the baffle 4 from affecting the ventilation flow of the air duct in the shell 1, and prevent the movable part 3 from interfering with the volute 2 and affecting the thickness of the entire machine.

[0180] In some embodiments, the fourth angle a4 has an angle range of [30°, 110°].

[0181] The baffle 4 and the movable part 3 are projected on a cross section perpendicular to the central axis L of the volute 2. From the projection diagram, the fourth angle a4 is the angle formed by the seventh line L7 and the eighth line L8. The seventh line L7 is the line connecting the fifth end 61 of the overlapping segment 6 in the rotation direction and the center C of the volute 2. The eighth line L8 is the line connecting the sixth end 62 of the overlapping segment 6 in the rotation direction and the center C of the volute 2. The fifth end 61 and the sixth end 62 are the two ends of the overlapping segment 6 that are farthest apart in the rotation direction.

[0182] The position of the volute tongue formed by the movable part 3 and the volute 2 is basically determined by the air outlet direction. The baffle 4 needs to be compatible with the air inlet position of both wind directions. a4 has a certain correlation with a1, a2, and a3. When the air outlet direction is fixed and a1 is freely set, if a4 is too large or too small, the air inlet condition will not be smooth, resulting in excessive air volume attenuation. According to the prototype test data in the following table:

[0183] Therefore, the angle range of the fourth angle a4 is preferably: [30°, 110°].

[0184] The fourth angle a4 can also be defined as: the angle formed by the line connecting the two ends of the overlapping segment of the projection of the movable part 3 and the baffle 4 on the cross section perpendicular to the central axis L of the volute 2 and the rotation center of the fan blade.

[0185] Preferably, 50°≤a4≤90°.

[0186] The overlapping section of the projection of the movable part 3-shaped line and the baffle 4-shaped line is fixed and has nothing to do with the transformation of the air outlet.

[0187] In the above embodiment, the angle range of the fourth angle a4 is: [30°, 110°]. On the basis of the above-mentioned definition of the baffle 4 and the movable part 3 profile line, the relative position of the baffle 4 and the volute 2 is further defined, which can prevent the baffle 4 from affecting the ventilation flow of the air duct in the shell 1 and prevent the movable part 3 from interfering with the volute 2 and affecting the thickness of the entire machine.
