Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a vertical air conditioner indoor unit. Background Technology

[0002] With the development of the times and the progress of technology, users not only expect air conditioners to have faster cooling and heating speeds, but also pay more and more attention to the comfort performance of air conditioners.

[0003] Existing vertical air conditioner indoor units typically have a vertical strip-shaped air outlet on the front of the casing, which is used to oscillate the air up, down, left, and right through an air guide device to expand the air delivery angle.

[0004] Based on this, some existing technologies have made many improvements to the air outlet structure. However, due to the constraints of the air outlet's orientation, the air supply direction, air supply range, and air supply distance of the air conditioner are still greatly limited. In particular, the problem of cold air blowing into people during cooling is difficult to solve, affecting the user experience. Summary of the Invention

[0005] The purpose of this invention is to overcome or at least partially solve the above problems, and to provide an air conditioning indoor unit with a more comfortable temperature for cold or hot air.

[0006] Another objective of this invention is to achieve the switching of different air outlet directions in a more unique and ingenious way, thereby enhancing the user experience.

[0007] Specifically, the present invention provides an indoor air conditioning unit, comprising:

[0008] The casing extends in a vertical column shape and defines at least one air duct;

[0009] At least one diverter, each diverter being disposed at the outlet of one of the air ducts to separate the outlet of the air duct into a first air outlet and a second air outlet located on either side of the diverter; and

[0010] A cover plate is movably mounted to the housing between a closed position and an open position;

[0011] In the open position, the cover is located outside the section of the housing adjacent to one of the first air outlets, so as to allow the first air outlet and the second air outlet to jointly discharge air, and to allow indoor airflow to flow along the gap between the cover and the housing to merge into the airflow discharged from the first air outlet.

[0012] In the closed position, the cover plate blocks the second air outlet to allow air to exit from the first air outlet.

[0013] Optionally, each of the air ducts is defined by a first air duct wall and a second air duct wall transversely arranged side by side, and each of the air ducts is defined by the first air duct wall and the second air duct wall and the flow splitter.

[0014] The outlet end of the first air duct wall is located obliquely behind the outlet end of the second air duct wall, so that the first air outlet is used for transversely blowing air when the cover plate is in the closed position, and the second air outlet is used for forward blowing air when the cover plate is in the open position.

[0015] Optionally, each of the first air outlets is provided with a deflector plate movable between a first position and a second position.

[0016] In the first position, the deflector plate opens the first air outlet; in the second position, the deflector plate extends forward from the front of the first air duct wall, so as to guide the air flow of the first air outlet to blow forward.

[0017] Optionally, when the deflector plate is in the second position, the inner wall of the deflector plate gradually decreases in distance from the second air duct wall in the direction of the air flow, so that the air flows of the first air outlet and the second air outlet gradually approach under the guidance of the inner wall of the deflector plate and the second air duct wall respectively, and are aggregated outside the cabinet.

[0018] Optionally, the second air duct wall comprises a first concave section and a second concave section connected in sequence from back to front, and the outlet end of the second concave section constitutes the outlet end of the second air duct wall.

[0019] Optionally, the deflector plate extends in the front-rear direction and is installed in the cabinet in a front-rear translatable manner.

[0020] Optionally, the number of air ducts is two, and the two air ducts are arranged transversely side by side along the cabinet.

[0021] The two second air outlets are forwardly open and adjacently arranged; and

[0022] The number of cover plates is one, and when the cover plate is in the closed position, it blocks the front side of the two flow splitters to shield the two second air outlets; when the cover plate is in the open position, it is located outside one of the transverse side walls of the cabinet.

[0023] Optionally, when the cover plate is in the closed position, it is spaced apart from the two flow splitters to allow the air flow of the second air outlet to flow through the spacing between the cover plate and the flow splitters and merge into the air flow of the first air outlet.

[0024] Optionally, the cover plate is an arc-shaped plate vertically extending along an axis, and is rotatably mounted on the cabinet about the axis thereof to rotate between the open position and the closed position.

[0025] Optionally, the outlet of the air duct is a vertical strip.

[0026] The flow divider is vertically columnar, and the cross section thereof is entirely oval or olive-shaped.

[0027] Optionally, the flow divider is configured to rotate about an axis parallel to the length direction thereof; and / or

[0028] The flow divider is configured to translate in a direction approaching or moving away from the outlet of the air duct.

[0029] The indoor unit of the vertical air conditioner separates the outlet of the air duct into a first air outlet and a second air outlet by using a flow divider, and achieves various air supply modes by using a movable cover plate. Different needs of users in different situations are fully met, and the air feeling experience of the users is better. When the cover plate is in the open position, the first air outlet and the second air outlet jointly supply air, and the air supply amount is larger. In addition, indoor air flows along the gap between the cover plate and the cabinet to mix with the air flow of the first air outlet, and a mixed air effect is formed. When the indoor unit of the vertical air conditioner is in a cooling mode, the mixing of the indoor air can increase the temperature of the air flow, so as to avoid that the temperature is too low and causes the human body to be uncomfortable when the air is blown to the human body. When the indoor unit of the vertical air conditioner is in a heating mode, the mixing of the indoor air can decrease the temperature of the air flow, so as to avoid that the temperature is too high and causes the human body to be dry and hot when the air is blown to the human body. In addition, the indoor unit of the vertical air conditioner is configured to guide the indoor air to mix with the air flow by using a guide vane, and a separate air guiding component is not additionally arranged, so that the mixed air structure of the wall-mounted air conditioner indoor unit is extremely simple. In addition, when the cover plate is in the closed position, the cover plate blocks the second air outlet to allow the first air outlet to supply air, and the air supply amount is smaller. The indoor unit of the vertical air conditioner is configured to guide the indoor air to mix with the air flow by using a cover plate, and a separate air guiding component is not additionally arranged, so that the mixed air structure of the vertical air conditioner indoor unit is extremely simple.

[0030] Further, in the indoor unit of the vertical air conditioner, the cover plate and the guide vane are used to change the air supply direction of the first air outlet. When the cover plate is in the closed position, the guide vane is away from the first air outlet, so that the first air outlet supplies air in a horizontal direction, and a horizontal air supply mode is formed. When the cover plate is in the open position, the guide vane extends forward from the front of the first air duct wall, so as to guide the air flow of the first air outlet to blow forward. In addition, the flow divider, the guide vane and the second air duct wall are further used to guide the air flow blown forward, so that the air flows of the first air outlet and the second air outlet are aggregated outside (the front side) of the cabinet, an aggregated air supply + mixed air mode is achieved, the air force is stronger, and the air supply distance is farther.

[0031] Further, the cross section of the flow dividing member is oval or olive-shaped, so that the flow loss is smaller when the air flow is divided to the two sides. In addition, the size of the first air outlet and the second air outlet can be changed by rotating and / or translating the flow dividing member, so that the size and / or the ratio of the air flow of the two air outlets can be changed. The design is very ingenious.

[0045] The present application provides a vertical air conditioner indoor unit. The vertical air conditioner indoor unit is the indoor part of the air conditioner, which is used to adjust the indoor air, such as refrigeration / heat, dehumidification, introduction of fresh air, etc.

[0046] Figure 1 is a structural schematic diagram of the vertical air conditioner indoor unit of an embodiment of the present application; Figure 2 is a schematic sectional view obtained by cutting the vertical air conditioner indoor unit of the present application in a horizontal plane; Figure 3 is Figure 2 is a schematic diagram of the vertical air conditioner indoor unit shown in FIG. 1 when the air deflector 60 moves to the first position; Figure 4 is Figure 2 is a schematic diagram of the vertical air conditioner indoor unit shown in FIG. 1 when the cover plate 80 moves to the open position. It should be noted that each figure only illustrates some optional air supply modes of the present application, and some air supply modes are not explicitly listed and introduced.

[0047] As Figures 1 to 4As shown, the indoor unit of the vertical air conditioner according to the embodiments of the present application generally comprises a casing 10, at least one flow divider 50, and a cover plate 80.

[0048] The casing 10 extends vertically in a columnar shape, and defines at least one air duct 20. The casing 10 according to the embodiments of the present application comprises a skeleton for constituting the basic frame of the indoor unit, and a volute, a volute tongue, and other body components for defining the air duct 20. The air duct 20 is connected to an opening in the outer wall of the casing 10, and the opening in the outer wall constitutes the outlet of the air duct 20. The indoor unit of the vertical air conditioner is configured to generate conditioned air, which is blown to the indoor environment through the outlet of the air duct 20, to complete the process of conditioning the indoor air. The conditioned air can be cold air generated by the indoor unit of the vertical air conditioner in a cooling mode, or hot air generated by the indoor unit of the vertical air conditioner in a heating mode. The number of air ducts 20 can be one or more, and the embodiments shown in the figures each illustrate an embodiment in which the number of air ducts 20 is two.

[0049] Each flow divider 50 is arranged at the outlet of an air duct 20 to divide the outlet of the air duct 20 into a first air outlet 11 and a second air outlet 12 on the two sides of the flow divider 50. As shown in the figures, Figure 2 The two ends of the outlet of each air duct 20 are denoted as A and B. The space between the flow divider 50 and the outlet end (A end) of the air duct 20 constitutes the first air outlet 11, and the space between the flow divider 50 and the outlet end (B end) of the air duct 20 constitutes the second air outlet 12. When the air is blown out of the air duct 20, it is divided by the flow divider 50 into two paths, and flows to the first air outlet 11 and the second air outlet 12, respectively, when both the first air outlet 11 and the second air outlet 12 are open.

[0050] The cover plate 80 is movably mounted on the casing 10 between a closed position and an open position. When the number of air ducts 20 is more than one, one cover plate 80 can be matched to the outlet of each air duct 20, or one cover plate 80 can be matched to the outlets of multiple air ducts 20, as shown in the figures. Figures 2 to 4 As shown in the figures, Figure 3 In the closed position, the cover plate 80 blocks the second air outlet 12 to allow air to be blown out of the first air outlet 11. As shown in the figures, Figure 4 In the open position, the cover plate 80 is located outside the section 101 of the casing 10 adjacent to a first air outlet 11 to allow air to be blown out of the first air outlet 11 and the second air outlet 12 together, and to allow indoor air to flow along the space 83 between the cover plate 80 and the casing 10 to join the air blown out of the first air outlet 11.

[0051] Specifically, after the air flow flows out from the first air outlet 11 at high speed, a negative pressure environment is formed near the first air outlet 11, and the faster the flow rate of the air flow is, the greater the negative pressure is. Under the action of the negative pressure, the indoor air flow between the cover plate 80 and the cabinet 10 is sucked into the negative pressure space and then mixed into the air flow. Due to the existence of the cover plate 80, the indoor air flow between the cover plate 80 and the cabinet 10 can only flow towards the negative pressure space in one way, which promotes the mixing process of the indoor air flow and the air flow. When the vertical air conditioner indoor unit is in the cooling mode, the mixing of the indoor air flow can increase the temperature of the air flow, so as to avoid that the temperature of the air flow is too low to cause the human body to be uncomfortable when the air flow blows to the human body. When the vertical air conditioner indoor unit is in the heating mode, the mixing of the indoor air flow can reduce the temperature of the air flow, so as to avoid that the temperature of the air flow is too high to cause the human body to be dry and hot when the air flow blows to the human body. Moreover, the air conditioner indoor unit of the present application uses the air deflector 60 to guide the indoor air flow to mix into the air flow, without needing to additionally arrange a separate air guiding component, which makes the mixing structure of the wall-mounted air conditioner indoor unit extremely simple.

[0052] In the air conditioner indoor unit of the embodiment of the present application, when the cover plate 80 is in the open position, the first air outlet 11 and the second air outlet 12 jointly blow air and have a mixing effect, and when the cover plate 80 is in the closed position, the second air outlet 12 is shielded to mainly blow air by the first air outlet 11. This makes the air supply adjustment mode of the vertical air conditioner indoor unit very rich, so as to facilitate the vertical air conditioner indoor unit to adjust different air supply modes according to different operation conditions and different user needs, to activate the corresponding air outlet and stop other air outlets, so as to change the overall air direction, air volume and the like of the vertical air conditioner indoor unit, so as to enable the user to obtain a better air supply experience.

[0053] In some embodiments, as shown in Figures 2 to 4 each air duct 20 is defined by the first air duct wall 21 and the second air duct wall 22 which are transversely arranged side by side, and the first air duct wall 21 and the second air duct wall 22 respectively define the first air outlet 11 and the second air outlet 12 with the flow dividing piece 50. The outlet end (A) of the first air duct wall 21 is located obliquely behind the outlet end (B) of the second air duct wall 22, so that when the cover plate 80 is in the closed position, the first air outlet 11 is used to blow air transversely, as shown in Figure 3 ; and when the cover plate 80 is in the open position, the second air outlet 12 is used to blow air forwardly, as shown in Figure 4 . This makes the range of the air supply angle of the vertical air conditioner indoor unit larger.

[0054] Further, as shown in Figures 2 to 4 each first air outlet 11 can be provided with an air deflector 60 which can move between a first position and a second position. In the first position, the air deflector 60 opens the first air outlet 11, as shown in Figure 3, to allow the first air outlet 11 to blow air laterally, forming a lateral air blowing mode. In the second position, the air deflector 60 extends forward from the first air duct wall 21, so as to guide the air flow 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 outlet 11 to blow air laterally, so that the first air outlet 11 cannot blow air laterally; on the other hand, the air deflector 60 guides the air flow of the first air outlet 11 to flow forward, so that the first air outlet 11 and the second air outlet 12 blow air forward together, and the air volume of forward air blowing is larger.

[0055] Further, as shown in Figure 4 , when the air deflector 60 is in the second position, the distance between the inner wall of the air deflector 60 and the second air duct wall 22 gradually decreases in the direction of the air flow (that is, the direction from the inside of the air duct 20 to the outside of the air duct 20), so that the air flows of the first air outlet 11 and the second air outlet 12 gradually approach under the guidance of the inner wall of the air deflector 60 and the second air duct wall 22 respectively, to aggregate on the outside of the cabinet 10, forming an aggregated air blowing effect. At the same time, under the guidance of the cover plate 80, indoor air flows synchronously into the aggregated air flow.

[0056] Specifically, due to the addition of the flow divider 50, during the adjustment of the air flow to flow forward, the air flow is guided to flow to the two sides of the flow divider 50, respectively, to flow out of the gap between the flow divider 50 and the second air duct wall 22 and the gap between the flow divider 50 and the inner wall of the air deflector 60, respectively, under the guidance of the rear surface of the flow divider 50, so that the air flow speed is faster. And because the distance between the inner wall of the air deflector 60 and the second air duct wall 22 gradually decreases, the two air flows gradually aggregate towards the center of the air flow during the outward flow, converging into one, so that the air force is very strong, the air blowing distance is farther, and the demand of the vertical air conditioner indoor unit for long-distance air blowing and strong air blowing is met.

[0057] In summary, the vertical air conditioner indoor unit of the present application has a forward aggregated air blowing + mixed air mode and a lateral air blowing mode for selection. As shown in Figure 2 , when the vertical air conditioner indoor unit is in a shutdown state, the cover plate 80 is in a closed position, and the air deflector 60 is in a second position, so that the first air outlet 11 and the second air outlet 12 are both blocked. As shown in Figure 3 , when the cover plate 80 is in a closed position and the air deflector 60 is in a first position, the vertical air conditioner indoor unit operates in a lateral air blowing mode. As shown in Figure 4 , when the cover plate 80 is in an open position and the air deflector 60 is in a second position, the vertical air conditioner operates in an aggregated air blowing + mixed air mode.

[0058] In some embodiments, as shown in Figures 2 to 4As shown, the air deflector 60 can extend in the front-rear direction and can be installed in the casing 10 in a front-rear translational manner. In this way, when the air deflector 60 is in the first position, it is located at the rear side of the outlet end (A) of the first air duct wall 21, so as not to affect the air flow of the first air outlet 11. Specifically, the casing 10 can be provided with an accommodating cavity 105 which is open at the front side, and when the air deflector 60 is in the first position, it is retracted into the accommodating cavity 105.

[0059] In some alternative embodiments, the rear end of the air deflector 60 can also be rotatably installed in the casing 10, and when in the first position, it can rotatably open or block the air supply path of the first air outlet 11 towards the lateral air supply.

[0060] In some embodiments, as shown in Figure 2 The second air duct wall 22 can include a first concave section DC and a second concave section CB which are connected to each other from the rear to the front, and the outlet end B of the second concave section CB constitutes the outlet end of the second air duct wall 22. This embodiment utilizes the first concave section DC and the first air duct wall 21 to form a conventional fan volute structure, so that the fan efficiency is higher. The concave shape of the second concave section CB is utilized to gradually reduce the distance between the adjacent outlet section of the second concave section CB and the air deflector 60 in the air flow direction, so as to achieve convergent air supply. It is preferred that the second concave section CB is arc-shaped.

[0061] In some embodiments, the outlet of the air duct 20 can be a vertical strip, i.e. a long strip extending in the length direction along the up-down direction. The flow dividing member 50 is a vertical column, and the cross section thereof is an oval or an olive shape as a whole, so that the flow loss is smaller during the process of air flow impacting the surface of the flow dividing member 50 and then being divided to the two sides. The flow dividing member 50 can be configured to rotate around an axis which is parallel to the length direction thereof; and / or the flow dividing member 50 can be configured to translate in the direction approaching or away from the outlet of the air duct 20. That is, the flow dividing member 50 can be capable of rotating, or capable of translating, or both. The embodiments of the present application can change the sizes of the first air outlet 11 and the second air outlet 12, and thus change the sizes and proportions of the air supply amounts of the two air outlets, by rotating and / or translating the flow dividing member 50, which is a very ingenious design.

[0062] Figure 5 is Figure 4 is a schematic view of the vertical air conditioner indoor unit after the flow dividing member 50 is rotated by an acute angle; Figure 6 is Figure 4 is a schematic view of the vertical air conditioner indoor unit after the flow dividing member 50 is rotated by 90°.

[0063] As shown in Figures 4 to 6 The rotation axis of the flow dividing member 50 can pass through or be close to the center of the oval or olive shape. As can be seen, the oval or olive shape has a major axis and a minor axis. As shown in Figure 4When the long axis (the axis through the two tips a and b) of the elliptical or olive-shaped flow divider 50 extends substantially along the width direction of the outlet of the air duct 20, the widths of the first air outlet 11 and the second air outlet 12 are the smallest; when the long axis extends substantially perpendicular to the width direction of the outlet of the air duct 20, the widths of the first air outlet 11 and the second air outlet 12 are the largest, as shown in Figure 6 In the embodiments of the present application, the flow divider 50 is provided in an elliptical or olive shape, and the distance between the flow divider 50 and the inner walls on both sides of the width direction of the air duct 20 can be changed by rotating the flow divider 50 about a fixed axis, so that the air outlet areas of the two air outlets can be adjusted. The structure is very simple, and no complicated driving mechanism is needed. Of course, the flow divider 50 can also be provided in other shapes. For example, the flow divider 50 can be provided in a non-cylindrical column shape. Alternatively, the flow divider 50 can be provided in a cylindrical shape but the rotation axis deviates from the central axis. The above structures can also change the sizes of the two air outlets by rotating the flow divider 50 about a fixed axis.

[0064] The olive shape and the elliptical shape are both composed of two convex surfaces, and the connection between the two large surfaces forms the two tips (a and b). As shown in Figure 6 When the air conditioner indoor unit operates in the convergent air supply mode, one of the two convex surfaces is preferably directed towards the inside of the air duct 20, and the airflow is smoothly dispersed to the two tips of the flow divider 50 in the transverse direction, that is, to the two air outlets, by using the convex surface. The other convex surface is directed towards the outdoor environment, and under the action of the Coanda effect, the airflow at the two air outlets can flow along the surface of the convex surface towards the center, which helps to converge the two airflows.

[0065] Figure 7 is a schematic view of a vertical air conditioner indoor unit after the flow divider 50 is translated towards the outlet of the air duct 20; Figure 4 is a schematic view of a translation driving mechanism of the flow divider 50. Figure 8 Please refer to

[0066] andAfter the flow divider 50 is translated towards the outlet of the air duct 20, that is, translated towards the inside of the air duct 20, the first air outlet 11 and the second air outlet 12 are both reduced in size. After the flow divider 50 is translated towards the outlet of the air duct 20, that is, translated towards the inside of the air duct 20, the first air outlet 11 and the second air outlet 12 are both increased in size. Figure 4 Figure 7 As shown in The gear and rack mechanism can be used to drive the flow divider 50 to translate, the rack 51 is connected to the flow divider 50, the gear 52 is engaged with the rack 51, and the gear 52 is driven to rotate in opposite directions by a motor, so that the rack 51 moves back and forth, and the flow divider 50 is driven to translate back and forth.

[0067] As shown in Figure 8 The gear and rack mechanism can be used to drive the flow divider 50 to translate, the rack 51 is connected to the flow divider 50, the gear 52 is engaged with the rack 51, and the gear 52 is driven to rotate in opposite directions by a motor, so that the rack 51 moves back and forth, and the flow divider 50 is driven to translate back and forth.

[0068] In some embodiments, as shown in Figures 1 to 7As shown, the number of air ducts 20 can be two, and the two air ducts 20 are arranged side by side along the transverse direction of the housing 10. Furthermore, the two air ducts 20 can be symmetrical with respect to a vertically extending plane. Two second air outlets 12 are open to the front and arranged adjacent to each other. There is one cover plate 80. When the cover plate 80 is in the closed position, it covers the front side of the two diverter members 50 to shield the two second air outlets 12; when the cover plate 80 is in the open position, it is located on the outside of a transverse sidewall 101 of the housing 10.

[0069] In some embodiments, reference Figure 3 This arrangement ensures that when the cover plate 80 is in the closed position, it forms a gap 81 with the two diverter members 50, allowing the airflow from the second air outlet 12 to flow through the gap 81 between the cover plate 80 and the diverter members 50 and merge into the airflow from the first air outlet 11. This results in a larger volume of lateral airflow and prevents airflow from accumulating between the diverter members 50 and the second duct wall 22, which would lead to poor airflow and loss of cooling / heating.

[0070] In some embodiments, please refer to Figure 2 and Figure 4 The cover plate 80 is an arc-shaped plate extending vertically along its axis (X3), rotatably mounted on the housing 10 about its own axis X3, allowing it to rotate between an open and closed position, thus simplifying the motion structure. In some embodiments, a motor can be designed at the axis X3, with a connecting arm between the motor shaft and the cover plate 80, driving the cover plate 80 to rotate via the motor. In other embodiments, an arc-shaped slide rail is provided on the housing 10, allowing the cover plate 80 to be slidably disposed within the arc-shaped slide rail. The cover plate 80 is connected by an arc-shaped rack, with the gear meshing with the rack. A motor drives the gear, causing the rack to move, ultimately moving the cover plate 80 along the arc-shaped slide rail (equivalent to rotating about X3).

[0071] like Figure 2 As shown, each air duct 20 has a vertically arranged cross-flow fan 40 at its inlet, and a heat exchanger 30 is arranged behind the two cross-flow fans 40. The lateral sides of the heat exchanger 30 can be bent forward to abut against the walls of the two first air ducts, thereby completely blocking the inlets of the two air ducts 20. An air inlet is provided on the rear side of the casing 10. The vertical air conditioner indoor unit can be an indoor unit of an air conditioner that uses a vapor compression refrigeration cycle system for cooling / heating. Under the action of the cross-flow fans 40, the indoor airflow enters the casing 10 through the air inlet, exchanges heat with the heat exchanger 43, and is then guided by the air ducts 20 and blown into the indoor environment through the air outlet to regulate the indoor air.

[0072] The indoor unit of the vertical air conditioner can include a human body position detection device connected with a main control board of the air conditioner. The human body position detection device is used to detect the distance L between the human body and the indoor unit of the vertical air conditioner. When L is greater than or equal to a first preset distance, the main control board controls the cover plate 80 and the air deflector 60 of the indoor unit of the vertical air conditioner to move to the corresponding positions to run the integrated air supply + mixed air mode. When L is less than the first preset distance, the cover plate 80 and the air deflector 60 are controlled to move to the corresponding positions to run the horizontal air supply mode, so that the air supply is performed on both sides of the casing 10, and the air flow does not blow on the human body, and the space is surrounded by the air supply.

[0073] Further, when the indoor unit of the air conditioner runs the integrated air supply + mixed air mode, when L is greater than or equal to a second preset distance (the second preset distance is less than the first preset distance), the flow divider 50 is rotated and / or translated to reduce the first air outlet 11 and the second air outlet 12, so that the wind speed is faster. When L is less than the second preset distance, the flow divider 50 is rotated and / or translated to increase the first air outlet 11 and the second air outlet 12, so that the wind speed is reduced, the mixed air amount is larger, and the human body does not feel strong cold air or hot air.

[0074] At this point, those skilled in the art should recognize that although the present application has been fully shown and described with reference to the various exemplary embodiments thereof, many other variations or modifications can be determined or deduced directly from the disclosure of the present application in accordance with the principles of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all such other variations or modifications.
