In the open position, the cover plate is located outside the section of the casing adjacent to one of the first air supply ports, so as to allow the first air supply port and the second air supply port to jointly discharge air, and to allow The indoor air flow flows along the gap between the cover plate and the casing, so as to merge into the air outlet air flow of the first air supply port;

In the closed position, the cover plate blocks the second air supply port to allow the first air supply port to discharge air.

Optionally, each of the air passages is defined by a first air passage wall and a second air passage wall arranged side by side, which respectively define the first air supply opening and the second air supply opening with the flow divider. tuyere;

The outlet end of the first air channel wall is located obliquely behind the outlet end of the second air channel wall, so that when the cover plate is in the closed position, the first air supply port can be used to send air laterally; When the cover plate is in the open position, the second air outlet is used to blow air forward.

Optionally, each of the first air outlets is provided with an air deflector movable between a first position and a second position;

In the first position, the air deflector opens the first air outlet; in the second position, the air deflector extends forward from the front of the first air channel wall so as to guide the first The air outlet airflow of the first air supply port is blown forward.

Optionally, when the air deflector is in the second position, the distance between the inner wall of the air deflector and the wall of the second air duct gradually decreases in the airflow direction, so that the first air supply port Guided by the inner wall of the air deflector and the wall of the second air channel, the air flow from the air outlet and the second air supply port gradually approaches to converge outside the casing.

Optionally, the second air duct wall includes a first concave section and a second concave section connected from the rear to the front, and the outlet end of the second concave section constitutes the opening of the second air duct wall. export port.

Optionally, the wind deflector extends along the front-to-rear direction, and is mounted on the casing in a front-to-back translational manner.

Optionally, the number of the air ducts is two, and they are arranged side by side along the lateral direction of the casing;

The two second air outlets are open to the front and arranged adjacent to each other; and

The number of the cover plate is one, and when the cover plate is in the closed position, it covers the front sides of the two flow dividers to cover the two second air supply ports; Outboard of one lateral side wall of the housing in the open position.

Optionally, when the cover plate is in the closed position, a space is formed between the two flow dividers, so as to allow the air outlet of the second air supply port to pass through the space between the cover plate and the flow dividers. The space flows into the air supply air flow of the first air supply port.

Optionally, the cover plate is an arc-shaped plate whose axis extends vertically, and is rotatably mounted on the casing around its own axis, so as to rotate between the open position and the closed position.

Optionally, the outlet of the air duct is in the shape of a vertical bar;

The flow divider is in the shape of a vertical column, and its cross-section is generally elliptical or olive-shaped.

Optionally, the diverter is configured to be rotatable around an axis parallel to its length direction; and/or

The flow divider is configured to translate in a direction approaching or away from the outlet of the air duct.

The indoor unit of the vertical air conditioner of the present invention separates the air outlet of the air duct into the first air supply port and the second air supply port by means of the flow divider, and utilizes the movable cover plate to realize various air supply modes. In order to fully meet the different needs of users in different situations, the user's wind experience is better. When the cover plate is in the open position, the first air supply port and the second air supply port can jointly discharge air, so that the air output can be larger. Moreover, the indoor airflow flows along the gap between the cover plate and the casing, so as to merge into the airflow from the first air supply port to form an air mixing effect. When the indoor unit of the vertical air conditioner is in the cooling mode, the mixing of the indoor airflow can increase the temperature of the outlet airflow, so as to prevent the temperature from being too low and causing discomfort to the human body. When the indoor unit of the vertical air conditioner is in the heating mode, the mixing of the indoor airflow can lower the temperature of the outlet airflow, so as to prevent its temperature from being too high and making the human body dry and hot when it is blown to the human body. Moreover, the present invention utilizes the air deflector to guide the indoor airflow to mix into the outlet airflow, and does not need to set up a separate air-introduction component, which makes the air-mixing structure of the wall-mounted air conditioner indoor unit extremely simple. In addition, when the cover plate is in the closed position, the cover plate blocks the second air supply port to allow the first air supply port to discharge air, and the air volume is smaller. The present invention utilizes the cover plate to guide the indoor airflow to mix into the outlet airflow, without additionally providing a separate air-introduction component, which makes the air-mixing structure of the indoor unit of the vertical air conditioner extremely simple.

Further, in the vertical air conditioner indoor unit of the present invention, the cover plate and the wind guide plate are used to realize the change of the air supply direction of the first air supply port. When the cover plate is in the closed position, the air deflector is kept away from the first air supply port, so that the first air supply port blows air laterally to form a horizontal air supply mode. When the cover plate is in the open position, the air deflector is extended forward from the front of the first air channel wall, so as to guide the air flow from the first air outlet to blow forward. In addition, the flow divider, the air deflector and the second air channel wall can be further used to guide the airflow blowing forward, so that the airflow of the first air supply port and the second air supply port can be aggregated on the outside (front side) of the casing to achieve aggregation. The air supply + mixed air mode makes the wind stronger and the air supply distance longer.

Furthermore, in the indoor unit of the vertical air conditioner of the present invention, the cross section of the flow divider is generally elliptical or olive-shaped, so that after the airflow hits the surface of the flow divider, the flow loss in the process of diverting to both sides is smaller. In addition, the present invention can change the size of the first air supply port and the second air supply port by rotating and/or translating the splitter, and then change the size and/or ratio of the air supply volumes of the two, which is a very ingenious design.

The invention provides a vertical air conditioner indoor unit. The indoor unit of the vertical air conditioner is the indoor part of the air conditioner, which is used to adjust the indoor air, such as cooling/heating, dehumidification, introducing fresh air, etc.

Fig. 1 is a schematic structural view of a vertical air conditioner indoor unit according to an embodiment of the present invention; Fig. 2 is a schematic sectional view obtained by cutting the vertical air conditioner indoor unit of the present invention on a horizontal plane; Fig. 3 is a vertical air conditioner indoor shown in Fig. 2 4 is a schematic diagram of the vertical air conditioner indoor unit shown in FIG. 2 when the cover plate 80 moves to the open position. It should be noted that each figure only shows some optional air supply modes of the present invention, and some air supply modes are not clearly listed and introduced.

As shown in FIGS. 1 to 4 , the vertical air conditioner indoor unit according to the embodiment of the present invention may generally include a casing 10 , at least one flow divider 50 , and a cover plate 80 .

Wherein, the casing 10 extends in a vertical column shape, and the casing 10 defines at least one air duct 20 . The casing 10 described in the embodiment of the present invention includes a skeleton for constituting the basic frame of the indoor unit and body components such as a volute and a volute tongue for defining an air duct 20 . The air duct 20 communicates with the opening of the outer wall of the casing 10 , and the opening of the outer wall forms an outlet of the air duct 20 . The conditioned air taken by the vertical air conditioner indoor unit is blown to the indoor environment through the outlet of the air duct 20 to complete the process of regulating the indoor air. The regulated airflow can be the cold air produced by the indoor unit of the vertical air conditioner in the cooling mode, and the hot air produced in the heating mode. The number of air ducts 20 may be one or multiple, and each figure shows an embodiment in which the number of air ducts 20 is two.

Each splitter 50 is disposed at the outlet of an air duct 20 to separate the outlet of the air duct 20 into the first air outlet 11 and the second air outlet 12 located on both sides of the splitter 50 . As shown in FIG. 2 , the two ends of the outlet of each air duct 20 are A and B respectively. The space formed between the flow divider 50 and the outlet end (end A) of the air duct 20 is the first air supply port 11, and the space formed between the flow divider 50 and the exit end (B end) of the air duct 20 is the second air supply port. 12. When both the first air supply port 11 and the second air supply port 12 are open, when the air flow is blown out from the air duct 20, it is divided into two paths by the splitter 50, and flows to the first air supply port 11 and the second air supply port 12 respectively. .

The cover plate 80 is movably installed on the casing 10 between a closed position and an open position. When there are multiple air ducts 20 , the outlet of each air duct 20 can be matched with one cover plate 80 , and the outlets of multiple air ducts 20 can be matched with one cover plate 80 , as shown in FIGS. 2 to 4 . As shown in FIG. 3 , in the closed position, the cover plate 80 blocks the second air supply port 12 to allow the first air supply port 11 to discharge air. As shown in FIG. 4 , in the open position, the cover plate 80 is located on the outside of the section 101 adjacent to the first air supply port 11 of the casing 10, so as to allow the first air supply port 11 and the second air supply port 12 to discharge air together, and The indoor air flow is allowed to flow along the gap 83 between the cover plate 80 and the casing 10 to merge into the air outlet air flow of the first air outlet 11 .

Specifically, after the airflow flows out from the first air supply port 11 at a high speed, a negative pressure environment is formed near the first air supply port 11, and the faster the flow velocity of the air flow, the greater the negative pressure. Under the effect of negative pressure, the indoor airflow between the cover plate 80 and the casing 10 will be sucked into the negative pressure space, and then merged into the outlet airflow. Due to the existence of the cover plate 80, the indoor airflow between the cover plate 80 and the casing 10 can only flow toward the negative pressure space, which promotes the mixing process of the indoor airflow and the outlet airflow. When the indoor unit of the vertical air conditioner is in the cooling mode, the mixing of the indoor airflow can increase the temperature of the outlet airflow, so as to prevent the temperature from being too low and causing discomfort to the human body. When the indoor unit of the vertical air conditioner is in the heating mode, the mixing of the indoor airflow can lower the temperature of the outlet airflow, so as to prevent its temperature from being too high and making the human body dry and hot when it is blown to the human body. Moreover, the present invention utilizes the air deflector 60 to guide the indoor airflow to mix into the outlet airflow, and does not need a separate air-introduction component, which makes the air-mixing structure of the wall-mounted air conditioner indoor unit extremely simple.

In the air-conditioning indoor unit of the embodiment of the present invention, when the cover plate 80 is in the open position, the first air supply port 11 and the second air supply port 12 can jointly output air and have an air mixing effect; when the cover plate 80 is in the closed position, the second The second air supply port 12 is blocked so that the air is mainly discharged from the first air supply port 11 . This makes the air supply adjustment mode of the indoor unit of the vertical air conditioner very rich, which is convenient for the indoor unit of the vertical air conditioner to adjust different air supply modes according to different operating conditions and user needs, enable the corresponding air supply outlet, and disable other air supply. The air outlet is used to change the overall air direction, air volume, etc. of the indoor unit of the vertical air conditioner, so that users can obtain a better air supply experience.

In some embodiments, as shown in FIG. 2 to FIG. 4 , each air channel 20 is defined by a first air channel wall 21 and a second air channel wall 22 that are arranged side by side in a horizontal direction, and both of them define the first air channel wall 21 with the flow divider 50 respectively. One air supply port 11 and the second air supply port 12 . The outlet end (A) of the first air channel wall 21 is located at the oblique rear of the outlet end (B) of the second air channel wall 22, so that when the cover plate 80 is in the closed position, the first air supply port 11 is used to send air laterally, as FIG. 3 ; when the cover plate 80 is in the open position, the second air outlet 12 is used to blow air forward, as shown in FIG. 4 . This makes the air supply angle range of the indoor unit of the vertical air conditioner as a whole larger.

Further, as shown in FIGS. 2 to 4 , each first air outlet 11 may be provided with an air deflector 60 that can move between a first position and a second position. In the first position, the air deflector 60 opens the first air supply port 11 , as shown in FIG. 3 , so as to allow the first air supply port 11 to blow air laterally, forming a horizontal air supply mode. In the second position, the air deflector 60 extends forward from the front of the first air duct wall 21, so as to guide the air outlet airflow of the first air outlet 11 to blow forward, as shown in Figure 4 . That is, in the second position, the air deflector 60 blocks the path of the first air supply port 11 for lateral air supply on the one hand, so that it cannot supply air laterally; Make the first air supply port 11 and the second air supply port 12 blow air forward together, so that the air volume of the air blown forward is larger.

Further, as shown in FIG. 4 , when the air deflector 60 is in the second position, in the airflow direction (that is, the direction from the inside of the air duct 20 to the outside of the air duct 20 ), the inner wall of the air guide plate 60 is in contact with the second airflow direction. The distance between the channel walls 22 gradually becomes smaller, so that the outlet airflows of the first air supply port 11 and the second air supply port 12 are gradually approached under the guidance of the inner wall of the air deflector 60 and the second air channel wall 22, so that the machine The outside of the shell 10 is aggregated to form an aggregated air supply effect. At the same time, under the guidance of the cover plate 80, the indoor airflow is synchronously mixed into the polymerization airflow.

Specifically, due to the addition of the flow divider 50, during the forward flow of the regulated airflow, it flows to both sides of the flow divider 50 under the guidance of the rear surface of the flow divider 50, respectively flows to the space between the flow divider 50 and the second air duct wall 22. The gap between the gap and the gap between the splitter 50 and the inner wall of the wind deflector 60 flows out, and the air outlet speed is faster. And because the distance between the inner wall of the wind deflector 60 and the second air duct wall 22 gradually decreases, the two streams of air flow gradually converge towards the center of the air stream during the outward flow process, and converge into one strand, making the wind force very strong and the air supply distance longer It meets the needs of vertical air conditioner indoor units for long-distance air supply and strong air supply.

In a word, the indoor unit of the vertical air conditioner of the present invention has a forward convergent air supply+mixed air mode and a lateral air supply mode for selection. As shown in Fig. 2 , when the indoor unit of the vertical air conditioner is stopped, the cover plate 80 is in the closed position, and the air deflector 60 is in the second position, so that both the first air outlet 11 and the second air outlet 12 are blocked. As shown in FIG. 3 , when the cover plate 80 is in the closed position and the wind deflector 60 is in the first position, the indoor unit of the vertical air conditioner operates in the horizontal air supply mode. As shown in FIG. 4 , when the cover plate 80 is in the open position and the air deflector 60 is in the second position, the vertical air conditioner operates in the combined air supply + mixed air mode.

In some embodiments, as shown in FIGS. 2 to 4 , the wind deflector 60 can extend along the front-to-back direction, and can be mounted on the casing 10 in a front-to-back translational manner. In this way, when the air deflector 60 is in the first position, it is located behind the outlet end (A) of the first air duct wall 21 so as not to affect the air flow from the first air outlet 11 . Specifically, the casing 10 may be provided with a receiving cavity 105 with an open front side, and when the wind deflector 60 is in the first position, it is retracted into the receiving cavity 105 .

In some alternative embodiments, the rear end of the air deflector 60 can also be rotatably installed on the casing 10, and when it is in the first position, it can be rotated to open or block the first air outlet 11 to blow air in the lateral direction. supply air path.

In some embodiments, please refer to FIG. 2 , the second air channel wall 22 can be made to include a first concave section DC and a second concave section CB connected from the rear to the front, and the outlet end of the second concave section CB B constitutes the outlet end of the second air duct wall 22 . In this embodiment, the first concave section DC and the first air channel wall 21 are used to form a traditional fan volute structure, so that the efficiency of the fan is higher. Utilizing the concave shape of the second concave section CB, the distance between the adjacent outlet section of the second concave section CB and the air deflector 60 gradually decreases along the airflow direction, so as to realize convergent air supply. Preferably, the second concave segment CB is arc-shaped.

In some embodiments, the outlet of the air duct 20 may be in the shape of a vertical strip, that is, a long strip whose length direction extends in the up-down direction. The flow divider 50 is vertically columnar, and its cross-section is elliptical or olive-shaped as a whole, so that after the airflow hits the surface of the flow divider 50 , the flow loss in the process of splitting to both sides is smaller. The flow divider 50 can be configured to rotate around an axis parallel to its length direction; and/or the flow divider 50 can be configured to translate in a direction approaching or away from the outlet of the air duct 20 . That is, the flow divider 50 may be enabled to rotate, or to translate, or both. The embodiment of the present invention can change the size of the first air supply port 11 and the second air supply port 12 by rotating and/or translating the flow divider 50, and then change the size and ratio of the air supply volume of the two. The design is very ingenious.

Fig. 5 is a schematic diagram of the vertical air conditioner indoor unit shown in Fig. 4 after the diverter 50 is rotated at an acute angle; Fig. 6 is a schematic diagram of the vertical air conditioner indoor unit shown in Fig. 4 after the diverter 50 is rotated 90°.

As shown in FIGS. 4-6, the axis of rotation of the flow divider 50 may pass through the center of the oval or olive shape or near the center. It can be seen that an ellipse or an olive has a major axis and a minor axis. As shown in Figure 4, when the major axis of the oval or olive-shaped flow divider 50 (the axis passing through the two pointed ends of a and b) extends approximately along the width direction of the outlet of the air duct 20, the first air supply port 11 and the second air supply port 12 The width is the smallest; when the long axis extends approximately perpendicular to the outlet width direction of the air channel 20, the width of the first air supply port 11 and the second air supply port 12 is the largest, as shown in FIG. 6 . In the embodiment of the present invention, the flow divider 50 is set in an oval or olive shape, and the distance between it and the inner walls on both sides of the air duct 20 in the width direction can be changed by rotating it at a fixed axis, so as to realize the adjustment of the air outlet area of the two air supply ports, and the structure is very It is simple, and there is no need to set up a complicated driving mechanism. Of course, other shapes can also be used for the flow divider 50 . For example, the flow divider 50 is made into a non-cylindrical column shape. Alternatively, the flow divider 50 is cylindrical but the axis of rotation deviates from the central axis. The above structure can also change the size of the two air outlets by rotating the splitter 50 on a fixed axis.

Both the olive shape and the ellipse are composed of two convex curved surfaces as a whole, and the joints between the two large curved surfaces form two tips (a, b). As shown in FIG. 6 , when the indoor unit of the air conditioner operates in the combined air supply mode, it is preferable to make a convex curved surface face the inside of the air duct 20 , and use the convex curved surface to smoothly disperse the airflow to the two lateral tips of the flow divider 50 , That is, the two air outlets. Make the other convex curved surface face the outdoor environment, and the airflow can guide the airflow at the two air supply outlets to flow along the surface of the convex curved surface toward its center under the action of the Coanda effect, which is conducive to the aggregation of the two airflows.

FIG. 7 is a schematic diagram of the vertical air conditioner indoor unit shown in FIG. 4 after the flow divider 50 is translated in a direction away from the outlet of the air duct 20 ; FIG. 8 is a schematic diagram of the translation drive mechanism of the flow divider 50 .

Please refer to FIG. 4 and FIG. 7 , after the flow divider 50 is translated away from the outlet of the air duct 20 (that is, translated to the inside of the air duct 20 ), both the first air supply port 11 and the second air supply port 12 become smaller. After the flow divider 50 is translated toward the outlet of the air duct 20 (that is, translated to the inside of the air duct 20 ), both the first air supply port 11 and the second air supply port 12 become larger.

As shown in Figure 8, the rack and pinion mechanism can be used to drive the shunt 50 to translate, so that the rack 51 is connected to the shunt 50, the gear 52 is meshed with the rack 51, and the gear 52 is driven forward and reverse by a motor to make the rack 51 The reciprocating movement drives the shunt 50 to reciprocate and translate.

In some embodiments, as shown in FIGS. 1 to 7 , the number of air ducts 20 can be two, and the two air ducts 20 are arranged side by side along the lateral direction of the casing 10 . Further, the two air ducts 20 can be made symmetrical with respect to a vertical plane extending back and forth. The two second air outlets 12 open forward and are adjacent to each other. The number of the cover plate 80 is one, and when the cover plate 80 is in the closed position, it covers the front sides of the two flow dividers 50 to cover the two second air supply ports 12; The outer side of a lateral side wall 101 .

In some embodiments, referring to FIG. 3 , when the cover plate 80 is in the closed position, a gap 81 is formed with the two flow dividers 50 to allow the air outlet of the second air supply port 12 to flow through the gap between the cover plate 80 and the flow divider 50 The space 81 flows and merges into the air supply airflow of the first air supply port 11 . In this way, the air volume of the lateral air supply is larger, and it also prevents the airflow from stagnating between the flow splitter 50 and the second air duct wall 22 , resulting in poor flow and cooling/heat loss.

In some embodiments, please refer to FIG. 2 and FIG. 4 , the cover plate 80 is an arc-shaped plate extending vertically on the axis (X3), which is rotatably mounted on the casing 10 around its own axis X3, so as to be in the open position and Rotation between closed positions makes the movement structure very simple. In some embodiments, a motor can be designed at the axis X3, and a connecting arm is arranged between the rotating shaft of the motor and the cover plate 80, and the cover plate 80 is driven to rotate by the motor. In other embodiments, an arc-shaped slideway is provided on the casing 10, so that the cover plate 80 is slidably arranged in the arc-shaped slideway, and the cover plate 80 is connected through an arc-shaped rack, so that the gear meshes with the arc-shaped rack , using the motor to drive the gear to drive the arc-shaped rack to move, so that the cover plate 80 finally moves along the arc-shaped slideway (equivalent to rotating around X3).

As shown in FIG. 2 , there is a cross-flow fan 40 arranged vertically at the inlet of each air duct 20 , and a heat exchanger 30 is arranged behind the two cross-flow fans 40 . The lateral two sides of the heat exchanger 30 can be bent forward to abut against the two first air duct walls, thereby completely blocking the inlets of the two air ducts 20 . The rear side of the casing 10 is provided with an air inlet. The vertical air conditioner indoor unit may be an indoor unit of an air conditioner that utilizes a vapor compression refrigeration cycle system for cooling/heating. Under the action of the cross-flow fan 40, the indoor air enters the casing 10 through the air inlet, and after completing the heat exchange with the heat exchanger 30, it is guided by the air duct 20 and blows to the indoor environment through the air outlet, thereby cooling the indoor ambient air. adjust.

The vertical air conditioner indoor unit may include a human body position detection device, which is connected with the main control board of the air conditioner.
