Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to an indoor air conditioner unit and an air conditioning system. Background Technology

[0002] Air conditioning systems, as commonly used heat exchange devices in daily life, are used to regulate environmental parameters such as temperature and humidity in rooms to create a comfortable working environment. An air conditioning system includes an indoor unit, which blows out cool air, warm air, or natural wind to regulate indoor environmental parameters.

[0003] In existing technology, air conditioner indoor units use air deflectors to adjust the airflow direction. Users can adjust the air deflector to change the airflow direction and avoid being blown directly on.

[0004] However, existing technologies only change the direction of airflow, but it is difficult to create a gentle breeze that makes users feel comfortable. Utility Model Content

[0005] In view of the above problems, this application provides an indoor air conditioning unit and an air conditioning system for generating gentle breezes.

[0006] On one hand, this application provides an indoor air conditioning unit, including: a casing having an air outlet, the air outlet including two air outlet zones distributed along the length direction of the air outlet; an air guide device disposed at the air outlet and guiding the airflow of the air outlet, the air guide device including: a rotating shaft extending along the length direction of the air outlet; a plurality of air guide discs spaced apart on the rotating shaft along the length direction of the air outlet, the air guide discs being radially inclined relative to the rotating shaft, and the inclination directions of the air guide discs in the two air outlet zones being opposite.

[0007] When the indoor unit of the air conditioner in this application is operating, it discharges air through the air outlet area to blow cool air, warm air, or natural wind into the room. The air guiding device consists of multiple air guide discs spaced apart along the length of the air outlet on a rotating shaft, and the air guide discs are radially inclined relative to the rotating shaft, so that the rotation of the rotating shaft drives the air guide discs to rotate. When the inclined air guide discs rotate, they create a disturbance effect on the airflow flowing out of the corresponding air outlet, roughly along the axial direction of the rotating shaft.

[0008] The indoor unit of this air conditioner uses guide vanes in two adjacent air outlet zones with opposite tilt directions. This creates a secondary turbulence effect between the airflows exiting the adjacent air outlet zones after the primary turbulence is caused by the corresponding guide vanes. The airflow from the indoor unit of this air conditioner, under the influence of both primary and secondary turbulence, forms a gentle breeze that provides a comfortable experience for the user.

[0009] In some embodiments, the angle between the radial direction of the air guide plate and the axis of the rotating shaft is 40°-75°.

[0010] In some embodiments, the distance between two adjacent air guide plates belonging to the same air outlet area is 3cm-8cm.

[0011] In some embodiments, the ratio of the height of the projection of the air guide plate onto the reference plane to the height of the air outlet is 0.5-0.85, wherein the reference plane is perpendicular to the rotation axis.

[0012] In some embodiments, the air guide plate and the rotating shaft are an integral structure.

[0013] In some embodiments, the air guide plate is detachably connected to the rotating shaft, and the position of the air guide plate on the rotating shaft is adjustable.

[0014] In some embodiments, the indoor unit of the air conditioner further includes a drive device connected to the housing, the drive device being used to drive the rotating shaft to rotate.

[0015] In some embodiments, the indoor unit of the air conditioner further includes two drive devices, and the rotating shaft includes a first rotating shaft and a second rotating shaft, which are respectively located in the two air outlet zones; the first rotating shaft and the second rotating shaft are respectively connected to the two drive devices, and the two drive devices are respectively used to drive the first rotating shaft and the second rotating shaft to rotate.

[0016] In some embodiments, the air outlet is further provided with two mounting parts corresponding to the first rotating shaft and the second rotating shaft, and the first rotating shaft and the second rotating shaft are respectively rotatably connected to their corresponding mounting parts.

[0017] In some embodiments, the rotating shaft has a first rotational position, in which the airflows from the two air outlet areas are opposite to each other; the rotating shaft has a second rotational position, in which the airflows from the two air outlet areas converge.

[0018] On the other hand, this application also provides an air conditioning system, including the aforementioned indoor air conditioning unit.

[0019] The air conditioning system of this application, by setting the aforementioned indoor air conditioning unit, can generate a gentle breeze indoors, which helps to improve the user's physical comfort. Attached Figure Description

[0032] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] Air conditioning systems, as commonly used heat exchange devices in daily life, are used to regulate environmental parameters such as temperature and humidity in rooms to create a comfortable working environment. An air conditioning system includes an indoor unit, which blows out cool air, warm air, or natural wind to regulate indoor environmental parameters. In existing technology, the indoor unit uses an air deflector to adjust the airflow direction. Users can adjust the air deflector to avoid being blown directly on. However, existing technology only changes the airflow direction and fails to create a gentle breeze that is comfortable for the user. For example, when the indoor unit blows cold air, changing the direction of the cold air with an air deflector can prevent the cold air from blowing directly on the user; however, the cold air tends to concentrate in certain areas, reducing the user's comfort. Specifically, this can either cause the environmental parameters in the user's area to not be adjusted in time, reducing comfort, or some of the diverted but still relatively concentrated cold air may blow onto the user's body, further reducing comfort.

[0034] In view of this, this application provides an indoor air conditioning unit and an air conditioning system, which discharges air through two air outlet zones to blow cool air, warm air, or natural wind into the room. The air guiding device consists of multiple air guide discs spaced apart along the length of the air outlet on a rotating shaft, with the air guide discs radially inclined relative to the rotating shaft. The rotation of the rotating shaft drives the air guide discs to rotate. When the inclined air guide discs rotate, they create a primary disturbance effect on the airflow exiting the corresponding air outlet, approximately along the axial direction of the rotating shaft.

[0035] The indoor unit of this application sets the air guide vanes of two adjacent air outlet zones in opposite tilt directions, creating a secondary turbulence effect between the airflows after the adjacent air outlet zones are initially disturbed by the corresponding air guide vanes. Through the combined effects of primary and secondary turbulence, the indoor unit of this application generates a gentle breeze that provides a comfortable experience for the user. Furthermore, the primary and secondary turbulence effects of this indoor unit facilitate uniform airflow around the air outlet, thereby promoting the even adjustment of environmental parameters around the air outlet.

[0036] Reference Figure 1 As shown, the air conditioner indoor unit 100 provided in this application includes: a casing 110 and an air guide device 120. It should be noted that the air conditioner indoor unit 100 provided in this application can be a wall-mounted air conditioner indoor unit; or, a floor-standing air conditioner indoor unit; or, a ceiling-mounted air conditioner indoor unit. This embodiment mainly describes a wall-mounted air conditioner indoor unit.

[0037] Reference Figure 1 and Figure 2As shown, the casing 110 has an airflow channel. The casing 110 also has an air inlet and an air outlet 111 communicating with the airflow channel. The air inlet can be located on the top wall of the casing 110, and the air outlet 111 can be located at the bottom of the front panel of the casing 110. A heat exchanger and a cross-flow fan can be installed within the airflow channel. When the air conditioning system is in cooling mode, the heat exchanger acts as an evaporator, exchanging heat with the airflow flowing through the airflow channel to cool the airflow. When the air conditioning system is in heating mode, the heat exchanger acts as a condenser, exchanging heat with the airflow flowing through the airflow channel to heat the airflow. The cross-flow fan drives the airflow from the air inlet into the airflow channel, and after exchanging heat with the heat exchanger, it is discharged into the room from the air outlet 111.

[0038] For example, the housing 110 has a first wall panel 114 and a second wall panel 115 to define an air outlet 111. Understandably, cool air, warm air, or natural wind generated by the indoor unit of the air conditioner is blown into the room requiring regulation through the air outlet 111.

[0039] The air outlet 111 includes two air outlet zones 112 distributed along the length of the air outlet 111; the air guide device 120 is disposed at the air outlet 111 and guides the airflow of the air outlet 111. The air guide device 120 includes a rotating shaft 121 and multiple air guide discs 122.

[0040] The rotating shaft 121 extends along the length of the air outlet 111. For example, a support can be provided in the air outlet 111, with a hole for the rotating shaft 121 to pass through. The rotating shaft 121 is rotatably connected to the support by engaging with the hole, thus providing support for the rotating shaft. Alternatively, a hole for rotatably connecting the rotating shaft can be provided on the portion of the housing 110 facing the rotating shaft 121.

[0041] Multiple air guide plates 122 are spaced apart on the rotating shaft 121 along the length of the air outlet 111, and the air guide plates 122 are radially inclined relative to the rotating shaft 121. Exemplarily, the air guide plates 122 can rotate with the rotating shaft 121. When the inclined air guide plates 122 rotate with the rotating shaft 121, they can create a disturbance to the airflow passing through the spaced areas of the air guide plates 122. Exemplarily, the air guide plates 122 can be circular; or rectangular; or elliptical; or trapezoidal or rhomboid; or other irregular shapes.

[0042] For example, the air guide plate 122 can be sleeved on the rotating shaft 121 and fixed to the rotating shaft 121 by fasteners or adhesive; or, for example, the air guide plate 122 and the rotating shaft 121 can be an integral structure, such as an integral injection molded structure; or, for example, the air guide plate 122 can be sleeved on the rotating shaft 121, in which case the air guide plate 122 and the rotating shaft 121 can be connected by splines.

[0043] Furthermore, the guide vanes 122 of the two air outlet zones 112 are tilted in opposite directions. For example, through the primary disturbance effect of the corresponding guide vanes 122, the airflow in one of the two adjacent air outlet zones 112 flows along direction A, while the airflow in the other air outlet zone 112 flows along direction B. It can be understood that directions A and B have components along the axial direction of the rotation axis 121. Under the influence of these components, the airflow in direction A and the airflow in direction B will converge to form a disturbance, which can be considered as a secondary disturbance in one dimension.

[0044] For example, through the primary disturbance effect of the corresponding air guide plate 122, the airflow in one of the two adjacent air outlet zones 112 flows along the C direction, and the airflow in the other air outlet zone 112 flows along the D direction. It can be understood that the C and D directions have components along the axial direction of the rotation axis 121. Under the influence of this component, the airflow in the C direction and the airflow in the D direction will form a disturbance that is mutually opposed. This disturbance can be regarded as a secondary disturbance in another dimension.

[0045] Understandably, as the shaft rotates continuously, the two-dimensional secondary disturbances alternate.

[0046] For example, the rotating shaft 121 can be a single section; when the rotating shaft 121 is a single section, the air guide plates 122 located in the two air outlet zones 112 are both connected to this section of the rotating shaft 121. In this way, it is beneficial to arrange the air guide plates 122 of the two air outlet zones 112 in a more continuous manner.

[0047] Alternatively, for example, the rotating shaft 121 may include two sections that can rotate independently of each other. In this case, the air guide plate 122 of one of the two air outlet zones 112 is connected to one section of the rotating shaft, and the air guide plate 122 of the other air outlet zone 112 is connected to the other section of the rotating shaft. This allows for a relatively dispersed arrangement of the air guide plates 122 of the two air outlet zones 112.

[0048] Reference Figure 1 and Figure 2As shown, in some embodiments, the angle between the radial direction of the air guide plate 122 and the axis of the rotating shaft 121 is 40°-75°. For example, this angle can be 40°, 43°, 45°, 47°, 50°, 55°, 60°, 65°, 70°, or 75°. Of course, this application does not limit this; the angle between the radial direction of the air guide plate 122 and the axis of the rotating shaft 121 can be reasonably selected within the above range as needed. It is understood that when the angle between the radial direction of the air guide plate 122 and the radial direction of the rotating shaft 121 is 40° to 75°, it is beneficial for the rotating air guide plate 122 to have a better disturbance effect on the airflow.

[0049] Reference Figure 2 As shown, in some embodiments, the distance between two adjacent air guide plates 122 belonging to the same air outlet zone 112 is 3cm-8cm. For example, this distance can be 3cm, 4cm, 5cm, 6cm, 7cm, or 8cm. It is understood that a smaller distance is more conducive to increasing the number of airflow segments, thus improving the gentle breeze effect; a larger distance is conducive to reducing the airflow resistance. This application sets the distance between two adjacent air guide plates 122 belonging to the same air outlet zone 112 to 3cm to 8cm, which helps maintain reasonable airflow resistance and improve the gentle breeze effect.

[0050] Reference Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the ratio of the height of the projection of the air guide plate 122 onto the reference plane to the height of the air outlet 111 is 0.5-0.85, wherein the reference plane is perpendicular to the rotating shaft 121. The ratio of the height of the projection of the air guide plate 122 onto the reference plane to the height of the air outlet 111 is 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, or 0.85; however, this application does not impose any limitations on this, and the ratio can be reasonably selected within the above range. This ensures a good air guiding effect for the air guide device 120, thereby improving the gentle breeze effect.

[0051] Reference Figure 1 and Figure 3 As shown, in some embodiments, the air guide plate 122 and the rotating shaft 121 are an integral structure. For example, the air guide device 120 is an integral injection-molded structure. This results in higher structural stability for the air guide device 120 and also helps reduce noise during operation of the air guide plate 122 and the rotating shaft 121.

[0052] Reference Figure 1 and Figure 3As shown, in some embodiments, the air guide plate 122 is detachably connected to the rotating shaft 121. Furthermore, the position of the air guide plate 122 on the rotating shaft 121 is adjustable. For example, a sleeve is provided on the side of the air guide plate 122, and the sleeve is fixedly connected to the corresponding air guide plate 122. The air guide plate 122 has a hole for passing through the rotating shaft 121; this hole is coaxially located on the sleeve, and the air guide plate 122 fits the corresponding hole and sleeve onto the rotating shaft 121; the sleeve is detachably fixed to the rotating shaft 121 by fasteners. When it is necessary to adjust the position of the air guide plate 122 on the rotating shaft 121, the fasteners are loosened to release the fixation between the sleeve and the rotating shaft 121, allowing for adjustment.

[0053] Reference Figure 2 As shown, in some embodiments, the indoor unit 100 of the air conditioner further includes a drive device 130, which is connected to the housing 110 and is used to drive the rotating shaft 121 to rotate. The drive device 130 can provide continuous driving for the rotating shaft, which is beneficial for the continuity of the gentle breeze.

[0054] It should be noted that when the rotating shaft 121 is a single piece, a drive device 130 can be set to drive the rotating shaft 121 to rotate.

[0055] When the rotating shaft 121 is divided into two sections, the two sections of the rotating shaft 121 can be connected by a connecting component such as a coupling to enable transmission between different sections of the rotating shaft. In this case, a driving device 130 can be set to drive the rotation of the rotating shaft 121.

[0056] Alternatively, when the rotating shaft 121 has two sections, the drive device 130 is a dual-output shaft motor. It should be noted that the working shaft of the dual-output shaft motor extends to both sides of its base so that it can drive the load on both sides of the base respectively. One section of the rotating shaft 121 is connected to one end of the working shaft of the dual-output shaft motor, and the other section of the rotating shaft 121 is connected to the other end of the working shaft of the dual-output shaft motor so that the rotating shaft 121 is driven to rotate by the dual-output shaft motor.

[0057] In this way, by using a drive device 130 to drive two air guide devices 120, it is beneficial to reduce the number of parts in the indoor unit 100 of the air conditioner, reduce the space occupied by the drive device 130, achieve a reasonable layout of the air guide device 120 and the drive device 130 at the air outlet 111, and also help to reduce costs.

[0058] Alternatively, when the rotating shaft 121 is divided into two sections, a drive device 130 can be provided for each section to drive it separately.

[0059] Reference Figures 1 to 4As shown, in some embodiments, the indoor unit 100 of the air conditioner further includes two drive devices 130. The rotating shaft 121 includes a first rotating shaft 121a and a second rotating shaft 121b. It can be understood that the first rotating shaft 121a and the second rotating shaft 121b can be considered as two segments of the rotating shaft 121. The first rotating shaft 121a is located in one of the air outlet zones 112, and the second rotating shaft 121b is located in the other air outlet zone 112. The first rotating shaft 121a is connected to one of the drive devices 130; the second rotating shaft 121b is connected to the other drive device 130. The two drive devices 130 are respectively used to drive the first rotating shaft 121a and the second rotating shaft 121b to rotate. Thus, the first rotating shaft 121a and the second rotating shaft 121b are independently driven by their respective drive devices 130, which helps to ensure that both the first rotating shaft 121a and the second rotating shaft 121b can obtain higher driving power, maintain the disturbance force on the two air outlet zones 112, and improve the gentle breeze effect.

[0060] Furthermore, referring to Figures 1 to 4 As shown, the air outlet 111 is also provided with two mounting members 113 corresponding to the first rotating shaft 121a. The air outlet 111 is also provided with two mounting members 113 corresponding to the second rotating shaft 121b. The first rotating shaft 121a and the second rotating shaft 121b are respectively rotatably connected to their corresponding mounting members 113. It can be understood that the mounting members 113 can provide support for the rotating shaft 121. For example, the mounting member 113 can be a support formed on the housing 110. Alternatively, for example, the mounting member 113 can be detachably connected to the air outlet area 112. For example, further, a bearing can be provided on the mounting member to rotatably connect the rotating shaft 121 via the bearing.

[0061] Reference Figure 1 As shown, the rotating shaft 121 has a first rotational position. When the rotating shaft 121 is in the first rotational position, the airflows from the two air outlet zones 112 are directed away from each other, creating a mutually opposing disturbance. The rotating shaft has a second rotational position. When the rotating shaft 121 is in the second rotational position, the airflows from the two air outlet zones 112 converge. It should be noted that during the continuous rotation of the rotating shaft 121 in the same direction, the rotating shaft can alternate between the first and second rotational positions. This process creates a two-dimensional mutual disturbance in the airflow, which helps to improve the gentle breeze effect.

[0062] Reference Figure 1 and Figure 5As shown, in some embodiments, the air conditioner indoor unit 100 further includes an air guide plate 140, which is rotatably disposed at the air outlet 111 to open and close the air outlet 111. The rotation axis of the air guide plate 140 is parallel to the length direction of the air outlet 111. It can be understood that during operation, the air conditioner indoor unit 100 can control the airflow by adjusting the opening degree of the air guide plate 140; or, during operation, the air conditioner indoor unit 100 can create a further turbulence effect on the air outlet by adjusting the angle of the air guide plate 140 to further enhance the gentle breeze.

[0063] For example, a fixed arm 142 is provided on the side of the air guide plate 140 facing the air outlet 111. The first end of the fixed arm 142 is fixed to the air guide plate 140, and the second end of the fixed arm 142 is connected to the base of the rotation drive member 143. The working shaft of the rotation drive member 143 is connected to the first end of the support arm 144, so that the support arm 144 is driven to rotate relative to the fixed arm 142 by the rotation drive member 143. The support arm 144 is connected to the housing 110. By driving the support arm 144 to rotate relative to the fixed arm 142, the air guide plate 140 rotates relative to the air outlet 111.

[0064] Reference Figure 1 and Figure 5 As shown, in some embodiments, the air guide plate 140 is provided with a plurality of soft air holes 141 arranged in an array. It should be noted that the soft air holes 141 penetrate the air guide plate 140. For example, the soft air holes 141 may be circular; or, for example, they may be polygonal, such as triangular, rectangular, pentagonal, or hexagonal; or, for example, they may be elliptical; or, for example, they may be other irregular shapes.

[0065] The air outlet modes of the indoor unit 100 include a first air outlet mode and a second air outlet mode. In the first air outlet mode, the air guide plate 140 opens the air outlet 111. Understandably, in this mode, the indoor unit 100 outlets air from the opened air outlet 111. In the second air outlet mode, the air guide plate 140 closes the air outlet 111. It should be noted that in the second air outlet mode, the gentle breeze effect can be further enhanced by the simultaneous action of the air guide device 120 and the gentle breeze orifice 141. Understandably, when the airflow passes through the gentle breeze orifice 141 and blows into the room, the gentle breeze orifice 141 can further enhance the gentle breeze effect.

[0066] On the other hand, the air conditioning system provided in this application includes the aforementioned air conditioning indoor unit 100.

[0067] The air conditioning system of this application, by setting the aforementioned indoor air conditioning unit 100, can generate a gentle breeze indoors, which helps to improve the user's physical comfort.
