Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to a vertical air conditioner indoor unit. Background Art

[0002] Compared with a wall-mounted air conditioner indoor unit, a vertical air conditioner indoor unit has a larger capacity and stronger cooling and heating capabilities, and is usually placed in a relatively large indoor space such as a living room. Since the coverage area of the vertical air conditioner indoor unit is larger, 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 air conditioner power and noise, affecting the user experience. Summary of the Invention

[0003] The object of the present invention is to provide a vertical air conditioner indoor unit that overcomes or at least partially solves the above problems, so as to achieve better long-distance air supply and strong air supply effects.

[0004] A further object of the present invention is to make the air outlet form of the vertical air conditioner indoor unit adjustable.

[0005] In particular, the present invention provides a vertical air conditioner indoor unit, including:

[0008] A deflector disposed in the air duct and defining an air outlet gap with its tapered portion, for guiding the air flow to the air outlet gap so that the air flow gradually converges towards the center of the air flow under the guidance of the deflector and the inner wall of the air duct and flows out of the first air outlet and the first air outlet in sequence; wherein the width of the portion of the deflector in the air outlet gap is adjustable, so as to change the air outlet form of the first air outlet.

[0010] A housing defining an accommodation cavity therein, and at least one opening penetrating through the inside and outside of the housing being provided in the portion of the housing in the air outlet gap;

[0011] At least one baffle movably disposed in the accommodation cavity; and

[0012] At least one first driving mechanism is disposed in the accommodation cavity. The first driving mechanism is configured to: drive the baffle to rotate outwards so that at least a part of the baffle extends beyond the housing from the opening, thereby increasing the width of the part of the flow guide member in the air outlet gap; and drive the baffle to rotate inwards so that at least a part of the baffle retracts into the housing from the opening, thereby reducing the width of the part of the flow guide member in the air outlet gap.

[0013] Optionally, the housing includes a front housing and a rear housing. The opening is formed on the front housing, and the projection of the opening on the horizontal plane extends in the left-right direction.

[0015] Optionally, the flow guide member further includes: a mounting plate disposed in the accommodation cavity and fixed to the front housing.

[0016] The first driving mechanism includes a first motor and a first connecting rod. The first motor is fixed to the mounting plate, and the output shaft of the first motor is connected to the baffle through the first connecting rod, so that when the front housing rotates, the baffle is driven to rotate simultaneously.

[0017] Optionally, the flow guide member further includes:

[0018] A slideway ring is disposed in the accommodation cavity and fixed to the rear housing. An annular chute is formed on the front side of the slideway ring; a bearing ring is fitted in the annular chute, and a plurality of ball holes are formed in the bearing ring; and

[0019] A plurality of balls are fitted in the plurality of ball holes.

[0020] A movable ring is fitted in the annular chute, located on the front side of the bearing ring, and the movable ring is fixed to the front housing; and

[0021] A fixed ring is configured to movably connect the movable ring to the rear housing; wherein

[0022] The second driving mechanism includes a second motor, a first gear and a first rack. The first rack is disposed around the inner side wall of the movable ring, the first gear meshes with the first rack, and the second motor is used to drive the first gear to rotate so that the first rack rotates in the vertical plane, thereby driving the front housing to rotate relative to the rear housing in the vertical plane.

[0023] Optionally, the flow guide member further includes: a third driving mechanism disposed outside the housing for moving the flow guide member back and forth to adjust the distance between the flow guide member and the first air outlet; wherein the third driving mechanism includes a third motor, a second gear, and a second rack, the second rack is disposed to extend in the front-back direction and is fixed to the housing, the second gear meshes with the second rack, and the third motor is used to drive the second gear to rotate so that the second rack moves in the front-back direction, thereby driving the flow guide member to move in the front-back direction.

[0024] Optionally, the position of the air inlet is lower than that of the first air outlet, so that the air flow flows from bottom to top to the flow guide member, so that the air flow in the bottom section of the air outlet gap drives the air flow in the remaining sections to flow upward and forward together.

[0025] Optionally, a second air supply port is further opened on the casing;

[0026] The air duct has a second air outlet, the second air outlet faces the second air supply port, and the air duct is used to guide the air flow in the casing to the second air supply port; wherein

[0027] The first air supply port and the second air supply port are opened on the front side of the casing, and the first air supply port is above the second air supply port.

[0028] Optionally, the vertical air conditioner indoor unit further includes:

[0029] a sliding plate movably disposed at the second air supply port for opening and closing the second air supply port; and

[0030] a fourth driving mechanism for moving the sliding plate up and down to open and close the second air supply port; the fourth driving mechanism includes a third rack, a third gear, and a fourth motor, wherein the third rack is disposed to extend in the up-down direction and is fixed to the sliding plate; the third gear meshes with the third rack; the fourth motor is used to drive the third gear to rotate so that the third rack moves in the up-down direction, thereby driving the sliding plate to move in the up-down direction to open and close the second air supply port.

[0031] Optionally, the vertical air conditioner indoor unit further includes:

[0032] a heat exchanger disposed in the casing; and

[0033] a blower disposed in the casing for promoting indoor air to enter the casing to exchange heat with the heat exchanger, and then blowing out from the first air supply port and the second air supply port through the air duct.

[0034] In the vertical air conditioner indoor unit of the present invention, the inner wall of the air duct near its first air outlet is tapered, so that the cross-sectional area of the air flow gradually decreases along the air flow direction. Moreover, a guiding member inside the air duct and the tapered portion of the inner wall of the air duct define an air outlet gap. In this way, when the air flow (such as the heat exchange air flow, fresh air flow, etc.) entering the air duct from the air inlet flows towards the first air outlet, it will be blown towards the inner wall of the air duct under the guidance of the guiding member and finally flow into the air outlet gap. Since the cross-sectional area of the air outlet of the air outlet gap is smaller, the air outlet speed is higher. Under the guidance of the tapered inner wall of the air duct, the high-speed air flow gradually converges towards the center of the air flow during the outward flow process, forming a converging effect, making the wind force stronger and the air supply distance farther, meeting the requirements of the vertical air conditioner indoor unit for long-distance air supply and strong air supply.

[0035] In the vertical air conditioner indoor unit of the present invention, the guiding member not only defines an air outlet gap with the inner wall of the air duct to achieve the effect of increasing the air speed, but also can just guide the air flow towards the air outlet gap, or rather, force the air flow to flow towards the air outlet gap, so as to force the air flow to receive the converging guidance of the tapered 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 and adding a guiding member. Its structure is very simple, the cost is low, it is easy to realize mass production and promotion, and the concept is very ingenious.

[0036] In the vertical air conditioner indoor unit of the present invention, by setting the guiding member so that the width of the part in the air outlet gap is adjustable, the width of the guiding member will affect the structure of the gap defined between the guiding member and the air duct of the indoor unit, and further affect the air flow path, etc., so that the air outlet form of the first air supply port is adjustable, improving the user experience.

[0037] Furthermore, the guiding member of the vertical air conditioner indoor unit of the present invention forms an opening penetrating the inside and outside of the housing on the housing, and at least one movable baffle is arranged in the accommodating cavity of the housing. The first driving mechanism is used to drive the baffle to rotate outwards so that at least part of the baffle extends out of the housing from the opening, thereby increasing the width of the part of the guiding member in the air outlet gap, and driving the baffle to rotate inwards so that at least part of the baffle retracts into the housing from the opening, thereby reducing the width of the part of the guiding member in the air outlet gap, so that the size and position of the actual air outlet area of the air outlet gap can be changed, and further the air outlet form of the first air supply port can be changed.

[0053] As Figure 1 And Figure 2 Shown, the vertical air conditioner indoor unit 300 of the embodiment of the present invention includes: a housing 10, an air duct 20, and the aforementioned deflector 100. The housing 10 has an air outlet. In Figure 1 In the embodiment shown, the air outlet includes a first air outlet 11 and a second air outlet 13

[0054] The first air supply 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 indoor unit 300 of the vertical air conditioner 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 can also be provided on the housing 10 to introduce indoor air. The housing 10 can be defined by a front housing 101, a rear housing 102, and a base 103, and the rear housing 102 can include an upper rear housing 121 and a lower rear housing 122.

[0055] The air duct 20 is arranged 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 supply outlet 11. The air duct 20 is used to guide the air flow inside the housing 10 to the first air supply 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.

[0056] The deflector 100 is arranged inside the air duct 20 and defines an air outlet gap 15 with its tapered portion 150, and is used to direct the air flow towards the air outlet gap 15 so that the air flow gradually converges towards the center of the air flow under the guidance of the deflector 100 and the inner wall of the air duct 20 and flows out of the first air outlet 21 and the first air supply outlet 11 in sequence ( Figure 8 The air flow direction is indicated by an arrow in the figure). In the indoor unit 300 of the vertical air conditioner 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 deflector 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 (such as the heat exchange air flow, the fresh air flow, etc.) entering the air duct 20 from the air inlet 22 flows towards the first air outlet 21, it will be blown towards the inner wall of the air duct 20 under the guidance of the deflector 100 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 ( Figure 8 the x-axis in the figure) during the outward flow process, forming a converging effect, making the wind force stronger and the air supply distance farther, meeting the requirements of the indoor unit 300 of the vertical air conditioner for long-distance air supply and strong air supply. In the indoor unit 300 of the vertical air conditioner according to the embodiment of the present invention, the deflector 100 not only defines the air outlet gap 15 with the inner wall of the air duct 20 to achieve the effect of increasing the air speed, but also can just direct the air flow towards the air outlet gap 15, or rather, force the air flow to flow towards the air outlet gap 15 to force the air flow to receive the converging guidance of the tapered inner wall and form the final converging air outlet effect. The present invention achieves a very good converging air supply effect only by improving the shape of the air duct 20 and adding a deflector 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.

[0057] The flow guide member 100 of the vertical air conditioner indoor unit 300 according to the embodiment of the present invention is further configured such that the partial width of the flow guide member 100 in the air outlet gap 15 is adjustable, so as to change the air outlet form of the first air outlet 11. In the vertical air conditioner indoor unit 300 according to the embodiment of the present invention, by setting the partial width of the flow guide member 100 in the air outlet gap 15 to be adjustable, the width of the flow guide member 100 will affect the cooperation between the flow guide member 100 and the air duct 20 of the indoor unit 300, and further affect the air flow path, etc., so that the air outlet form of the first air outlet 11 is adjustable, improving the user experience. In this article, the width of the flow guide member 100 refers to the width of the projection of the flow guide member 100 on the vertical plane where the first air outlet 11 is located.

[0058] In some embodiments, the deflector 100 of the vertical air conditioner indoor unit 300 according to the embodiments of the present invention includes: 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 formed in a portion of the housing 110 located in the air outlet gap 15. 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 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, thereby increasing the width of the portion of the deflector 100 located in the air outlet gap 15; 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, thereby decreasing the width of the portion of the deflector 100 located in the air outlet gap 15. Herein, "rotating outward" and "rotating inward" 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 toward the inside of the housing 110 is the inward rotation of the baffle 200. Since the deflector 100 is disposed close to the first air outlet 21, the air flow inside the indoor unit 300 is guided by the external shape, i.e., the outer contour, of the deflector 100 during the flow through the deflector 100, and then flows out of the first air outlet 21 and the first air supply port 11. By forming the opening 130 penetrating the inside and outside of the housing 110 on the housing 110 and disposing at least one movable baffle 200 in the accommodation cavity 120 of the housing 110, the first driving mechanism is used 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 the first driving mechanism is used to 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 to adjust the width of the baffle 200, thereby adjusting the size and position of the actual air outlet area of the air outlet gap 15, etc. The change in the air outlet area affects the flow path of the air flow, which also changes the guiding effect of the air flow guided by the deflector 100, and at the same time makes the air outlet form of the indoor unit 300 adjustable.

[0059] 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. The deflector 100 can be such that multiple baffles 200 enter and exit the housing 110 from the same opening 130 (such as Figures 3 to 5As shown, it is also possible that each baffle 200 corresponds to one opening 130, and multiple openings 130 are arranged at intervals. Similarly, it is possible that one first driving mechanism corresponds to one baffle 200, or one first driving mechanism drives more than two baffles 200. Generally, the number of baffles 200 is multiple, and each baffle 200 is correspondingly provided with one first driving mechanism, and the number of openings 130 is one. This can simplify the processing technology of the housing 110. At the same time, multiple baffles 200 can be independently controlled and maintained, and setting multiple baffles 200 can diversify the movement combinations of the baffles 200, so that there can be more specific change states of the width of the flow guide member 100. As Figures 3 to 7 shown, the flow guide member 100 includes one opening 130 and three baffles 200, and the three baffles 200 respectively correspond to one first driving mechanism.

[0060] In some embodiments, the housing 110 includes a front housing 111 and a rear housing 112. The opening 130 is formed in the front housing 111, and the projection of the opening 130 on the horizontal plane extends in the left-right direction. The flow guide member 100 further includes: a second driving mechanism, which is arranged in the accommodation cavity 120 and is 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 flow guide member 100 of the embodiment of the present invention has a front housing 111 and a rear housing 112, with a simple structure and easy assembly; by forming the opening 130 in the front housing 111 and using 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, the width of the flow guide member 100 can be adjusted and the position can be changed. When the flow guide member 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 flow guide member 100.

[0061] For example, when the baffle 200 is controlled to extend upward out of the housing 110, the actual air outlet area of the air outlet gap 15 on the upper side of the flow guide member 100 will become narrower at this time, and the air outlet volume on the upper side 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 on the upper side of the flow guide member 100 will be completely blocked, and there will be no air outlet on the upper side 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 thus the air outlet direction can be adjusted. For example, by rotating the front housing 111, the baffle 200 extends out on the left side of the housing 110 and abuts against the inner wall of the air duct 20. At this time, 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 9As shown, the three baffles 200 are all 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 inside 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. And in Figure 10 and Figure 11 In, the three baffles 200 all 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 shielded, and the air flow inside the housing 10 can only flow out of the first air outlet 21 through the left part that is not shielded by the baffle 200. Figure 11 The position of the air outlet area at this time is marked.

[0062] Referring to Figure 2 and Figure 7 , the first air supply port 11 is opened on the front side of the housing 10, and the first air supply port 11 and the second air outlet 21 are circular ports. The front housing 111 has a front end portion 113 and a side wall portion 114 extending backward from the front end portion 113; the front end portion 113 has a smooth convex arc surface structure that protrudes forward. The projection of the front end portion 113 on the vertical plane is circular. The opening 130 is opened at the junction of the front end portion 113 and the side wall portion 114. In the embodiment of the present invention, when the air flow flows to the flow guide member 100, it first flows through the side wall portion 114, and then flows through the front end portion 113. The forward convex 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 better achieve aggregated air supply and the air supply distance is farther.

[0063] Referring to Figure 2 and Figure 12, 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, resulting in a larger air volume and stronger wind force in the bottom section of the air outlet gap 15 compared with 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. Moreover, the upward blowing of the air flow is also beneficial to increasing its air supply distance. It can be understood that when the baffle 200 covers 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. Reference Figure 2 and Figure 8 , in some embodiments, the streamline shape of the inner wall of the tapered portion 150 of the air duct 20 is the same as the line type of the corresponding portion of the deflector 100. Taking the streamline of the bottom section of the tapered portion 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 those of the corresponding sections of the front housing 111 of the deflector 100. By making the streamline shape of the inner wall of the tapered portion 150 of the air duct 20 the same as the line type of the corresponding portion of the deflector 100, the air outlet resistance can be further reduced and the air outlet intensity can be improved.

[0064] In some embodiments, the deflector 100 of the vertical air conditioner indoor unit 300 according to the embodiment of the present invention further includes: a mounting plate 500, which is arranged 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 rotates 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, and 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. Reference Figure 7, a rotating shaft hole 501 and a fixing hole (not labeled in the figure) are formed on the mounting plate 500.

[0066] In some embodiments, the flow guiding member 100 of the vertical air conditioner indoor unit 300 according to the embodiment 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 to adjust the distance between the flow guiding member 100 and the first air outlet 21; wherein 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 7 and Figure 12As shown in the figure, the flow guide member 100 includes two third driving mechanisms. Both of the second racks 701 extend in the front-back direction. Two second gears 802 are respectively arranged in corresponding gear seats 803, and the two gear seats 803 are respectively fixed to the fixed seat 204 in the air duct 20 of the indoor unit 300. By arranging the flow guide member 100 into a structure that can move back and forth, the distance between the flow guide member 100 and the first air outlet 21 can be adjusted, so that the air volume, air speed, and air supply distance of the indoor unit 300 are adjustable, enriching the air supply adjustment mode. In addition, the flow guide member 100 can also move to completely shield the first air outlet 21 so that the first air supply port 11 does not blow air at all.

[0067] In some embodiments, the flow guide member 100 of the vertical air conditioner indoor unit 300 according to the embodiment 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-back 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, and the second slide rail 902 is used to be fixed at the inner wall of the air duct 20, so as to provide guidance for the back-and-forth movement of the flow guide member 100. As Figure 7 shown in the figure, the flow guide 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 first slide rail 901 and the second slide rail 902 are adapted and relatively slid by fitting the convex ribs into the sliding grooves.

[0068] As described above, the housing 10 also has a second air supply port 13. The second air supply port 13 is also used to blow the air flow in the housing 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 supply port 13. The air duct 20 is used to guide the air flow in the housing 10 to the second air supply port 13. In Figure 1 the shown embodiment, the first air supply port 11 is above the second air supply port 13. In the heating mode, the hot air sent out from the second air supply port 13 can achieve a good downward blowing effect, which can improve the user's comfort. The second air supply port 13 is also a circular port.

[0069] The indoor unit 300 of the vertical air conditioner further includes: a slide plate 70 and a fourth driving mechanism. The slide plate 70 is movably arranged 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 extends 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 indoor unit 300 of the vertical air conditioner according to the embodiment of the present invention may further include a heat exchanger 50 and a blower 60. The heat exchanger 50 is arranged in the casing 10. The blower 60 is also arranged in the casing 10 and is used to urge indoor air to enter the casing 10 to exchange heat with the heat exchanger 50, and then blow out through the air duct 20 from the first air outlet 11 and the second air outlet 13.

[0071] As Figure 12 shown, the air duct 20 may include a front shell 201, a rear shell 202 and a water receiving tray 203. The rear side and the lower side of the front shell 201 are open, and the first air outlet 21 and the second air outlet 23 are arranged on the front shell 201 at intervals in the up-and-down direction. The front side and the lower side of the rear shell 202 are open, and the rear shell 202 covers the rear side of the front shell 201, jointly forming a structure with an open lower side. The water receiving tray 203 covers the lower sides of the front shell 201 and the rear shell 202 to close the open port 130 on 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 shell 201, the rear shell 202 and the water receiving tray 203, is convenient for independently processing and manufacturing each part to better meet the performance requirements. In addition, in order to facilitate the fixation of the gear seat 803 to the air duct 20, two fixing seats 204 are symmetrically arranged in the rear shell 202.

[0072] Reference Figure 2 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.
