Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to a flow guide member and an indoor air conditioner. Background Art

[0002] Compared with wall-mounted indoor air conditioners, floor-standing indoor air conditioners have a larger capacity and stronger cooling and heating capabilities, and are usually placed in large indoor spaces such as living rooms. Since the floor-standing indoor air conditioner has a larger coverage area, it is required to have stronger long-distance air supply ability and strong air outlet ability. In order to achieve long-distance air supply in existing products, the method of increasing the fan speed to increase the air speed and air volume is usually adopted. However, the increase in the fan speed will cause a series of problems such as an increase in the power consumption of the air conditioner and an increase in noise, affecting the user experience. In addition, existing flow guide members all have a fixed external structure, and the flow guide member can only achieve a single flow guiding effect, with limited applications and unable to meet the different air outlet requirements of users.

[0051] An embodiment of the present invention provides a flow guide member 100, including: a housing 110, at least one baffle 200, and at least one first driving mechanism. An accommodation cavity 120 is defined inside the housing 110, and at least one opening 130 penetrating the inside and outside of the housing 110 is provided on the housing 110. At least one baffle 200 is movably disposed in the accommodation cavity 120. At least one first driving mechanism is disposed in the accommodation cavity 120, and the first driving mechanism is configured to: drive the baffle 200 to rotate outward so that at least a part of the baffle 200 extends out of the housing 110 from the opening 130; and drive the baffle 200 to rotate inward so that at least a part of the baffle 200 retracts into the housing 110 from the opening 130.

[0052] In the embodiment of the present invention, the flow guide member 100 forms an opening 130 penetrating through the inside and outside of the housing 110 on the housing 110, and at least one movable baffle 200 is arranged in the accommodation cavity 120 of the housing 110. The first driving mechanism is used to drive the baffle 200 to rotate outwards so that at least part of the baffle 200 extends out of the housing 110 from the opening 130, and the first driving mechanism is used to drive the baffle 200 to rotate inwards so that at least part of the baffle 200 retracts into the housing 110 from the opening 130, so that the outer contour of the flow guide member 100 can be changed, and further the flow guiding effect of the flow guide member 100 can be adjusted. The flow guide member 100 in the embodiment of the present invention can be applied to the air conditioner indoor unit 300, and is arranged near the air outlet of the indoor unit 300, so that the air flow in the indoor unit 300 flows out of the air outlet after being guided by the flow guide member 100. The flow guide member 100 in the embodiment of the present invention can be used for a floor-standing air conditioner indoor unit 300, and can also be used for a wall-mounted air conditioner indoor unit. In this article, the flow guide member 100 will be described by taking the example of being arranged in the floor-standing air conditioner indoor unit 300. Since the flow guide member 100 is arranged near the air outlet, the air flow in the indoor unit 300 will flow out of the air outlet 11 after being guided by the external shape, that is, the outer contour of the flow guide member 100 to achieve flow guiding. In this article, "rotating outwards" and "rotating inwards" are defined relative to the inside of the housing 110. The rotation of the baffle 200 away from the inside of the housing 110 is the outward rotation of the baffle 200, and the rotation of the baffle 200 towards the inside of the housing 110 is the inward rotation of the baffle 200.

[0053] The number of the baffles 200 can be one or more, the number of the first driving mechanisms can be one or more, and the number of the openings 130 can be one or more. In the embodiment of the present invention, the flow guide member 100 can be such that multiple baffles 200 enter and exit the housing 110 from the same opening 130 (as Figure 2 shown), or each baffle 200 corresponds to an opening 130, and multiple openings 130 are arranged at intervals. Similarly, one first driving mechanism can correspond to one baffle 200, or one first driving mechanism can drive two or more baffles 200. Generally, the number of the baffles 200 is multiple, each baffle 200 is correspondingly provided with a first driving mechanism, and the number of the openings 130 is one. In this way, the processing technology of the housing 110 can be simplified. At the same time, multiple baffles 200 can be independently controlled and maintained, and the arrangement of multiple baffles 200 can diversify the movement combinations of the baffles 200, so that the change states of the outer contour of the flow guide member 100 can be more. As Figures 1 to 5 shown, the flow guide member 100 includes one opening 130 and three baffles 200, and the three baffles 200 respectively correspond to a first driving mechanism.

[0054] In some embodiments, the housing 110 includes a front housing 111 and a rear housing 112; an opening 130 is formed in the front housing 111 and / or the rear housing 112, and the projection of the opening 130 on the horizontal plane extends in the left-right direction. The deflector 100 of the embodiments of the present invention has a front housing 111 and a rear housing 112, with a simple structure and easy to assemble; by forming the opening 130 in the front housing 111 and / or the rear housing 112 and the projection of the opening 130 on the horizontal plane extending in the left-right direction, the width of the deflector 100 can be adjusted. When the deflector 100 is applied in the air conditioner indoor unit 300, the width of the deflector 100 will affect the structure of the gap defined between the deflector 100 and the housing or the air duct of the indoor unit 300, thereby making the air outlet form of the indoor unit 300 adjustable. In theory, the opening 130 can be formed in the housing 110 in various extending manners. Considering the actual application situation of the deflector 100 in the indoor unit 300, the opening 130 is arranged such that its projection on the horizontal plane extends in the left-right direction. Herein, the width of the deflector 100 refers to the width of the projection of the deflector 100 on the vertical plane where the air outlet is located when the deflector 100 is arranged at the air outlet. Specifically, in the indoor unit 300, the deflector 100 is usually arranged close to the air outlet, and there is a gap between the deflector 100 and the housing or the air duct of the indoor unit 300. The air flow flows through the gap and then reaches the air outlet. By arranging the opening 130 such that its projection on the horizontal plane extends in the left-right direction, the width of the baffle 200 can be adjusted, and thus the actual air outlet area of the aforementioned gap can be adjusted. The change in the air outlet area will affect the flow path of the air flow, which also changes the guiding effect of the air flow guided by the deflector 100, making the air outlet form of the indoor unit 300 adjustable.

[0055] In some embodiments, the opening 130 is formed in the front housing 111; the deflector 100 of the embodiments of the present invention further includes: a second driving mechanism, arranged in the accommodating cavity 120 and configured to drive the front housing 111 to rotate relative to the rear housing 112 in the vertical plane to adjust the relative position of the opening 130. The deflector 100 of the embodiments of the present invention forms the opening 130 in the front housing 111 and uses the second driving mechanism to drive the front housing 111 to rotate relative to the rear housing 112 in the vertical plane to adjust the relative position of the opening 130, so that the adjustable position of the width of the deflector 100 is variable. When the deflector 100 is applied in the air conditioner indoor unit 300, the air outlet direction of the indoor unit 300 can be adjusted by controlling the change of the relative position of the opening 130 of the deflector 100.

[0056] Such as Figure 5As shown, in some embodiments, the front housing 111 has a front end portion 113 and a side wall portion 114 extending rearward from the front end portion 113; the front end portion 113 has a smooth convex arc surface structure protruding forward; the opening 130 is formed at the junction of the front end portion 113 and the side wall portion 114. In the embodiments of the present invention, when the air flow reaches the flow guide member 100, it first flows through the side wall portion 114, and then through the front end portion 113. The forwardly protruding structure of the front end portion 113 can enable the flow guide member 100 itself to have a certain effect of converging the air flow forward, so that the indoor unit 300 provided with the flow guide member 100 can achieve aggregated air supply and the air supply distance is farther.

[0057] In some embodiments, the flow guide member 100 of the embodiments of the present invention further includes: a mounting plate 500, which is disposed in the accommodation cavity 120 and fixed to the front housing 111. The first driving mechanism includes a first motor 301 and a first connecting rod 302. The first motor 301 is fixed to the mounting plate 500, and the output shaft of the first motor 301 is connected to the baffle 200 through the first connecting rod 302, so that when the front housing 111 rotates, the baffle 200 is driven to rotate simultaneously. By fixing the mounting plate 500 to the front housing 111, when the front housing 111 rotates, the mounting plate 500 can be driven to rotate simultaneously. The mounting plate 500 will further drive the baffle 200 to move, so that the relative position between the opening 130 and the baffle 200 remains unchanged, making the rotation of the baffle 200 easier to control. Continue to refer to Figure 5 , a rotating shaft hole 501 and a fixing hole (not labeled in the figure) are formed on the mounting plate 500. The first motor 301 is fixed to the mounting plate 500 on the rear surface of the mounting plate 500 by a fixing member through the fixing hole. The output shaft passes through the rotating shaft hole 501 and is connected to one end of the first connecting rod 302. The other end of the first connecting rod 302 is connected to the connecting column 210 on the rear surface of the baffle 200. The mounting plate 500 is generally a semi-circular ring-shaped sheet, and the three rotating shaft holes 501 are sequentially arranged at intervals along the inner arc surface. In addition, the three baffles 200 can also be arranged such that they partially overlap in the retracted state and there is an overlapping area at the junction of two adjacent baffles 200 in the fully extended state, as Figure 2 and Figure 4 shown.

[0058] In some embodiments, the flow guiding member 100 of the embodiments of the present invention further includes: a movable ring 604 and a fixed ring 605. The movable ring 604 is fixed to the front housing 111. The fixed ring 605 is configured to movably connect the movable ring 604 to the rear housing 112. The second driving mechanism includes a second motor 401, a first gear 403 and a first rack 640, wherein the first rack 640 is disposed around the inner sidewall of the movable ring 604, the first gear 403 meshes with the first rack 640, and the second motor 401 is used to drive the first gear 403 to rotate so that the first rack 640 rotates in the vertical plane and then drives the front housing 111 to rotate relative to the rear housing 112 in the vertical plane. By providing the movable ring 604, the fixed ring 605 and the second driving mechanism, 360° rotation of the front housing 111 in the vertical plane can be achieved. In order to reduce the friction when the movable ring 604 rotates, the flow guiding member 100 further includes: a slideway ring 601, a bearing ring 602 and a plurality of balls 603. The slideway ring 601 is disposed in the accommodation cavity 120 and is fixed to the rear housing 112. An annular chute 611 is formed on the front side of the slideway ring 601. The bearing ring 602 is fitted in the annular chute 611, and a plurality of ball holes 621 are formed in the bearing ring 602. The plurality of balls 603 are fitted in the plurality of ball holes 621. The movable ring 604 is fitted in the annular chute 611 and is located on the front side of the bearing ring 602. As Figure 5 shown, a plurality of first mounting holes 115 are spaced apart at the edge of the rear housing 112, and a plurality of second mounting holes 116 are spaced apart inside the rear housing 112. A fixing column 612 is formed on the rear back surface of the slideway ring 601, and the slideway ring 601 is fixed in the rear housing 112 by fitting the fixing column 612 with the second mounting holes 116 one by one. The bearing ring 602 is in the shape of an annular sheet and is disposed in the annular chute 611 of the slideway ring 601. A plurality of ball holes 621 are spaced apart around the bearing ring 602. The balls 603 are fitted in the ball holes 621, one side contacts the front surface of the slideway ring 601, and the other side contacts the rear surface of the movable ring 604. A fixing hole 641 is formed in the movable ring 604 along the front-rear direction, and a fixing column (not shown in the figure) is correspondingly formed on the inner side of the front housing 111. The movable ring 604 is fixed to the front housing 111 by fixing the fixing hole 641 and the fixing column of the front housing 111 with a fixing member. The second driving mechanism further includes a second connecting rod 402. One end of the output shaft of the second motor 401 is connected to one end of the second connecting rod 402, and the other end of the second connecting rod 402 is connected to the first gear 403. The gear seat 404 of the first gear 403 can be set to be connected to the front housing 111. A plurality of mounting holes 651 are spaced apart around the outer surface of the fixed ring 605, and the fixed ring 605 is fixed to the rear housing 112 by fixing the mounting holes 651 and the first mounting holes 115 with a fixing member. The fixed ring 605 can limit the movable ring 604, the bearing ring 602 and the slideway ring 601 at corresponding positions in the rear housing 112.

[0059] In some embodiments, the flow guiding member 100 of the embodiments of the present invention further includes: a third driving mechanism, which is arranged outside the housing 110 and is used to move the flow guiding member 100 in the front-rear direction. The third driving mechanism includes a third motor 801, a second gear 802 and a second rack 701. The second rack 701 extends in the front-rear direction and is fixed to the housing 110. The second gear 802 meshes with the second rack 701. The third motor 801 is used to drive the second gear 802 to rotate so that the second rack 701 moves in the front-rear direction, thereby driving the flow guiding member 100 to move in the front-rear direction. As Figure 5 and Figure 8 shown, the flow guiding member 100 includes two third driving mechanisms. Both second racks 701 extend in the front-rear direction. Two second gears 802 are respectively arranged in corresponding gear seats 803. The two gear seats 803 are respectively fixed to the housing or the air duct of the indoor unit 300. By setting the flow guiding member 100 into a structure that can move back and forth, the distance between the flow guiding member 100 and the air outlet can be adjusted, so that the air volume, air speed and air supply distance of the indoor unit 300 can be adjusted, enriching the air supply adjustment mode. In addition, the flow guiding member 100 can also move to make the air outlet where it is provided completely airless.

[0060] In some embodiments, the flow guiding member 100 of the embodiments of the present invention further includes: a first slide rail 901 and a second slide rail 902. The first slide rail 901 is arranged outside the housing 110 and is configured to extend in the front-rear direction and be fixed to the housing 110. The second slide rail 902 is adapted to the first slide rail 901 to achieve relative sliding. The second slide rail 902 is used to be fixed in the air conditioner indoor unit 300 provided with the flow guiding member 100, so as to provide guidance for the front-rear movement of the flow guiding member 100. As Figure 5 and Figure 8 shown, the flow guiding member 100 includes two first slide rails 901 and two second slide rails 902, forming two symmetrically arranged guiding mechanisms. The two first slide rails 901 are symmetrically arranged outside the rear housing 112. The specific cooperation form of the first slide rail 901 and the second slide rail 902 can adopt any structure that can achieve sliding in the prior art. For example, the first slide rail 901 has two convex ribs, and the second slide rail 902 correspondingly has two sliding grooves. The convex ribs are fitted into the sliding grooves to make the first slide rail 901 and the second slide rail 902 adapted and achieve relative sliding.

[0061] The following combines Figures 6 to 12 to make an exemplary description of the application of the flow guiding member 100 of the embodiments of the present invention. As Figure 6 and Figure 7As shown, there is a vertical air conditioner indoor unit 300 with a flow guide member 100 according to an embodiment of the present invention. The vertical air conditioner indoor unit 300 includes: a housing 10, an air duct 20, and the aforementioned flow guide member 100. The housing 10 has an air outlet. In Figure 6 the illustrated embodiment, the air outlet includes a first air outlet 11 and a second air outlet 13.

[0062] The first air outlet 11 is used to blow the air flow inside the housing 10 towards the room to adjust the indoor air. The aforementioned air flow can be the cold air produced by the vertical air conditioner indoor unit 300 in the cooling mode, the hot air produced in the heating mode, or the fresh air introduced in the fresh air mode, etc. An air inlet 12 may also be provided on the housing 10 for introducing indoor air. The housing 10 can be defined by a front housing 101, a rear housing 102, and a base 103. The rear housing 102 may include an upper rear housing 121 and a lower rear housing 122.

[0063] The air duct 20 is disposed inside the housing 10 and has an air inlet 22 and a first air outlet 21. The first air outlet 21 faces the first air outlet 11. The air duct 20 is used to guide the air flow inside the housing 10 to the first air outlet 11, and the inner wall of the air duct 20 near the first air outlet 21 is in a tapered shape with the cross-sectional area of the flow passage gradually decreasing along the air flow direction. In other words, near the first air outlet 21, along the air flow direction, the cross-sectional area of the air duct 20 gradually decreases.

[0064] The flow guide member 100 is disposed inside the air duct 20 and defines an air outlet gap 15 with its tapered portion 150, for guiding the air flow to the air outlet gap 15 so that the air flow gradually converges towards the center of the air flow under the guidance of the flow guide member 100 and the inner wall of the air duct 20 and then flows out of the first air outlet 21 and the first air outlet 11 in sequence ( Figure 8 the air flow direction is indicated by arrows). In the vertical air conditioner indoor unit 300 according to the embodiment of the present invention, the inner wall of the air duct 20 near its first air outlet 21 is in a tapered shape, so that the cross-sectional area of the flow passage gradually decreases along the air flow direction. Moreover, the flow guide member 100 inside the air duct 20 and the tapered portion 150 of the inner wall of the air duct 20 define an air outlet gap 15. In this way, when the air flow (heat exchange air flow, fresh air flow, etc.) entering the air duct 20 from the air inlet 22 flows towards the first air outlet 21, it will be guided by the flow guide member 100 to blow towards the inner wall of the air duct 20 and finally flow into the air outlet gap 15. Since the cross-sectional area of the air outlet of the air outlet gap 15 is smaller, the air outlet speed is higher. Under the guidance of the tapered inner wall of the air duct 20, the high-speed air flow gradually converges towards the center of the air flow during the outward flow process ( Figure 8Aggregate along the x-axis (in the middle), forming a converging effect, making the wind stronger and the air supply distance farther, meeting the requirements of the vertical air conditioner indoor unit 300 for long-distance air supply and strong air supply. In the vertical air conditioner indoor unit 300 of the embodiment of the present invention, the flow guide member 100 not only defines an air outlet gap 15 with the inner wall of the air duct 20 to achieve the effect of increasing the wind speed, but also exactly guides the air flow to the air outlet gap 15, or rather forces the air flow to flow towards the air outlet gap 15, so as to force the air flow to receive the converging guidance of the gradually shrinking inner wall and form the final converging air outlet effect. The present invention realizes a very good converging air supply effect only by improving the shape of the air duct 20 and adding a flow guide member 100. Its structure is very simple, the cost is low, it is easy to realize mass production and promotion, and the concept is very ingenious.

[0065] The opening 130 of the flow guide member 100 is opened at the part of the housing 110 that is in the air outlet gap 15. As Figure 8 and Figure 10 shown, the opening 130 of the flow guide member 100 is opened at the junction of the front end portion 113 and the side wall portion 114. By controlling the baffle 200 to extend or retract from the housing 110, the width of the part of the flow guide member 100 that is in the air outlet gap 15 can be adjusted, so as to adjust the size and position of the actual air outlet area of the air outlet gap 15, and further change the air outlet form of the first air outlet 11. For example, when the baffle 200 extends upward from the housing 110, the actual air outlet area of the air outlet gap 15 above the flow guide member 100 will become narrower and the air volume above will decrease; if the upper end of the baffle 200 abuts against the inner wall of the air duct 20, the air outlet gap 15 above the flow guide member 100 will be completely blocked, and there will be no air outlet above at this time. As described above, by rotating the front housing 111 relative to the rear housing 112, the relative position of the opening 130 can be changed, which also changes the position of the part of the air outlet gap 15 that the baffle 200 can adjust, and further the air outlet direction can be adjusted. For example, by rotating the front housing 111 to make the baffle 200 extend on the left side of the housing 110 and abut against the inner wall of the air duct 20, the air outlet gap 15 on the left side of the flow guide member 100 is blocked and there is no air outlet on the left side. As Figure 8 and Figure 9 shown, all three baffles 200 are in the retracted state and are located inside the housing 110. The air outlet gap 15 has an entire annular air outlet area, and the air flow in the housing 10 flows out of the first air outlet 21 through the entire annular air outlet gap 15. Figure 9 The position of the air outlet area at this time is marked in Figure 10 and Figure 11 In, all three baffles 200 rotate outward beyond the housing 110 and are in the extended state, and the ends of the parts of the three baffles 200 that extend beyond the housing 110 all abut against the inner wall of the air duct 20. Most of the area of the air outlet gap 15 is blocked, and the air flow in the housing 10 can only flow out of the first air outlet 21 through the unblocked left part.Figure 11 The position of the air outlet area at this time is marked out.

[0066] Reference Figure 7 and Figure 12 and, the position of the air inlet 22 is lower than that of the first air outlet 21, so that the air flow flows from bottom to top towards the deflector 100, so that the air flow in the bottom section of the air outlet gap 15 drives the air flow in the remaining sections to flow upwards and forwards together. By setting the position of the air inlet 22 lower than that of the first air outlet 21, in this way, the bottom section of the air outlet gap 15 is in the upstream of the air flow compared with other sections, so that the air flow will flow into the bottom section of the air outlet gap 15 more smoothly, so that the air volume in the bottom section of the air outlet gap 15 is larger and the wind force is stronger than that in the remaining sections. The strong air flow at the bottom has an advantage in the impact and aggregation process with the air flow in the upper part and the lateral sides of the air outlet gap 15, and more powerfully drives the overall air flow to flow upwards and forwards together, achieving a better upward air supply effect. In the cooling mode, the upward flowing cold air can fully avoid the human body, and then scatter downwards after reaching the highest point, realizing a "shower type" cooling experience and improving the user's comfort. And, the upward blowing of the air flow is also beneficial to improving its air supply distance. It can be understood that when the baffle 200 shields the bottom section of the air outlet gap 15, the upward blowing effect of the indoor unit 300 will disappear, but it still has an aggregated air outlet effect.

[0067] Reference Figure 8 and, in some embodiments, the streamline shape of the inner wall of the tapered part 150 of the air duct 20 is the same as the line type of the corresponding part of the deflector 100. Taking the streamline of the bottom section of the tapered part 150 as an example, it mainly includes the mn section and the np section, and the line types of the mn section and the np section are the same as the line types of some sections of the front shell 111 of the deflector 100. By making the streamline shape of the inner wall of the tapered part 150 of the air duct 20 the same as the line type of the corresponding part of the deflector 100, the air outlet resistance can be further reduced and the air outlet intensity can be improved.

[0068] As described above, the casing 10 also has a second air outlet 13. The second air outlet 13 is also used to blow the air flow in the casing 10 into the room to adjust the indoor air. The air duct 20 also has a second air outlet 23. The second air outlet 23 faces the second air outlet 13. The air duct 20 is used to guide the air flow in the casing 10 to the second air outlet 13. In Figure 6 the shown embodiment, the first air outlet 11 and the second air outlet 13 are opened on the front side of the casing 10, and the first air outlet 11 is above the second air outlet 13. In the heating mode, the hot air sent out from the second air outlet 13 can achieve a good downward blowing effect, which can improve the user's comfort. Both the first air outlet 11 and the second air outlet 13 are circular openings, the first air outlet 21 and the second air outlet 22 are also circular openings, and the projection of the front shell 111 of the deflector 100 on the vertical plane is also circular.

[0069] The vertical air conditioner indoor unit 300 further includes: a slide plate 70 and a fourth driving mechanism. The slide plate 70 is movably disposed at the second air outlet 13 for opening and closing the second air outlet 13. The fourth driving mechanism is used to move the slide plate 70 up and down to open and close the second air outlet 13, and includes a third rack 83, a third gear 82, and a fourth motor 81, wherein the third rack 83 is arranged to extend in the up and down direction and is fixed to the slide plate 70; the third gear 82 meshes with the third rack 83; the fourth motor 81 is used to drive the third gear 82 to rotate so that the third rack 83 moves in the up and down direction, thereby driving the slide plate 70 to move in the up and down direction to open and close the second air outlet 13. By providing the flow guide member 100 and the third driving mechanism, the first air outlet 11 can be opened and closed; by providing the slide plate 70 and the fourth driving mechanism, the second air outlet 13 can be opened and closed; in this way, the indoor unit 300 can realize air supply only through the first air outlet 11, only through the second air outlet 13, or through the first air outlet 11 and the second air outlet 13. In addition, a wind deflector 90 can be provided at the second air outlet 13 to adjust the air outlet direction of the second air outlet 13.

[0070] In some embodiments, the vertical air conditioner indoor unit 300 may further include a heat exchanger 50 and a blower 60. The heat exchanger 50 is disposed in the housing 10. The blower 60 is also disposed in the housing 10 and is used to urge indoor air to enter the housing 10 to exchange heat with the heat exchanger 50, and then blow out from the first air outlet 11 and the second air outlet 13 through the air duct 20.

[0071] As Figure 12 shown, the air duct 20 may include a front housing 201, a rear housing 202, and a water receiving tray 203. The rear side and the lower side of the front housing 201 are open, and the first air outlet 21 and the second air outlet 23 are spaced apart in the up and down direction and opened on the front housing 201. The front side and the lower side of the rear housing 202 are open, and the rear housing 202 covers the rear side of the front housing 201 to jointly form a structure with an open lower side. The water receiving tray 203 covers the lower sides of the front housing 201 and the rear housing 202 to close the open port 130 at its lower side. The air inlet 22 of the air duct 20 is opened on the water receiving tray 203. Decomposing the air duct 20 into three parts, namely the front housing 201, the rear housing 202, and the water receiving tray 203, is convenient for independently processing and manufacturing each part to better meet the performance requirements. In addition, as mentioned above, in order to facilitate the fixation of the gear seat 803 to the indoor unit 300, two fixing seats 204 are symmetrically arranged in the rear housing 202.

[0072] Reference Figure 7 and Figure 12, the heat exchanger 50 is arranged inside the air duct 20 and installed on the water receiving tray 203. The heat exchanger 50 can be a two-stage structure, including a first heat exchange section 51 and a second heat exchange section 52. Both heat exchange sections are flat and the top ends of the two heat exchange sections are connected. The bottom ends of the two heat exchange sections are placed on the water receiving tray 203 and are respectively located on both sides of the air inlet 22. This inverted "v" shape structure of the heat exchanger 50 can make it have a sufficiently large heat exchange area, and make it more fully contact with the airflow flowing upward from the air inlet 22, and the heat exchange efficiency is higher. A left tube sheet 53 and a right tube sheet 54 are also provided on the left and right sides of the two heat exchange sections, respectively, so that the airflow can fully contact the heat exchanger 50. The water receiving tray 203 is used to carry the heat exchanger 50 on the one hand, and on the other hand, it is used to receive condensed water dripping from the surface of the heat exchanger 50 during air conditioning cooling. The air duct 20 is located in the middle and upper part of the casing 10, and one or more air inlets 12 are opened in the lower part of the casing 10, for example Figure 12 As shown, the air inlet 12 is opened at the lower rear side of the housing 10. The fan 60 is installed below the air duct 20 and faces the air inlet 22 so that the airflow entering the lower space of the housing 10 from the air inlet 12 is blown into the air duct 20. The fan 60 can be as shown in FIG. Figure 12 The double suction centrifugal fan shown may also be a fan of other forms. When the fan 60 is a double suction centrifugal fan, it may include a volute 61, a motor 62, a fan 63, an air induction ring 64, and the like.
