Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, in particular to a wall-mounted air-conditioning indoor unit. Background Art

[0002] With the development of air-conditioning technology, the appearance and functions of wall-mounted air-conditioning indoor units are constantly updated, and various new technologies emerge in an endless stream.

[0003] However, there are very few innovative air guide structures for wall-mounted air conditioner indoor units. Existing solutions typically incorporate an air guide plate and a set of swinging blades at the air outlet. The plate adjusts the vertical angle of the air outlet, while the swinging blades provide left-right airflow. Existing wall-mounted air conditioner indoor units widely utilize this air guide structure, resulting in a consistent user experience and appearance, making it difficult to elevate the product's quality.

[0004] Therefore, how to achieve innovation in air-guiding structure has become a technical problem that needs to be solved urgently in the air-conditioning industry. Summary of the Invention

[0005] An object of the present invention is to provide a wall-mounted air conditioner indoor unit with a novel air guide device to enhance product differentiation and user experience.

[0006] A further object of the present invention is to enable a wall-mounted air conditioner indoor unit to select different air supply modes according to needs.

[0007] In particular, the present invention provides a wall-mounted air conditioner indoor unit, comprising:

[0008] a housing provided with an air outlet; and

[0009] An air guide device is arranged on the outside of the air outlet, and the air guide device includes a cylinder, and a accommodating space is defined in the cylinder. The peripheral wall of the cylinder includes an air inlet section and at least one air outlet section arranged along its circumference, so that the air flow from the air outlet passes through the air inlet section into the interior of the cylinder, and then blows toward the indoor environment through at least one of the air outlet sections.

[0010] Optionally, the air guide device further includes at least one air guide plate, which is rotatably disposed in the cylinder so as to guide the incoming airflow of the air inlet section to different air outlet sections or to different areas of the same air outlet section by rotating to different angles.

[0011] Optionally, there are multiple air outlet sections, each facing a different direction.

[0012] Optionally, the air guide device is provided at the lower front portion of the housing; and

[0013] The plurality of air outlet sections include at least one air outlet section for discharging air forward and at least one air outlet section for discharging air downward.

[0014] Optionally, a plurality of air dispersion holes are provided on the air outlet section that discharges air toward the front, and air outlet grilles are formed on the other air outlet sections.

[0015] Optionally, the cylinder is in the shape of a triangular prism, and the three sections of its peripheral wall respectively constitute one air inlet section and two air outlet sections.

[0016] Optionally, the air guide device is arranged at the lower front side of the shell; and one of the air outlet sections is located below the front panel of the shell, forming the front appearance of the shell, and the other air outlet section is open to the rear and lower side.

[0017] Optionally, each of the air guide plates is curved along the air flow direction so that its two ends are respectively perpendicular to the air inlet section and one of the air outlet sections.

[0018] Optionally, each of the air guide plates is in the shape of an elongated strip with its length direction parallel to the axial direction of the cylinder, and its rotation axis is parallel to its length direction.

[0019] Optionally, there are multiple air guide plates, which are sequentially spaced apart along the thickness direction of the air guide plate; and

[0020] One end of the plurality of air guide plates is fixedly connected to a fixed shaft, and the other ends are fixedly connected to another fixed shaft so as to rotate synchronously.

[0021] Optionally, the air guide device further includes two end covers, and the two end covers are fixed to the housing;

[0022] The two ends of the cylinder in the length direction are respectively fixed to the two end covers;

[0023] One of the end caps is provided with a motor;

[0024] One of the fixed shafts is connected to the motor, and the other fixed shaft is rotatably connected to the other end cover.

[0025] Optionally, the shell is a horizontally arranged long strip, in which an air duct for conveying airflow is provided; the length direction of the cylinder is parallel to the length direction of the shell, and is attached to the outside of the shell, and the air inlet section is located at the outlet of the air duct.

[0026] In the wall-mounted air conditioner indoor unit of the present invention, the airflow within the housing is not blown directly into the indoor environment. Instead, it first enters the cylinder of the air guide device, where it is gathered and then blown outward through one or more air outlet sections of the cylinder, directing the airflow in the direction indicated by the relevant air outlet section. This invention utilizes one or more air outlet sections on the cylinder to guide the airflow, resulting in a novel and ingenious structure.

[0027] Furthermore, in the wall-mounted air conditioner indoor unit of the present invention, the air guide plate is rotatably disposed within the cylinder. By rotating to different angles, the airflow from the air inlet section is directed to different air outlet sections, or to different areas within the same air outlet section, thereby adjusting the wind direction. The present invention conceals the air guide plate within the cylinder. When the air guide plate is guiding air or rotating back and forth to generate a swinging effect, the air guide plate is invisible. This subverts the appearance of the wall-mounted air conditioner indoor unit, making the product more upscale and providing a better user experience.

[0028] Furthermore, in the wall-mounted air conditioner indoor unit of the present invention, the cylinder is triangularly prism-shaped, precisely arranging its two air outlet sections, one facing forward and the other facing downward and rearward. In cooling mode, air is primarily delivered outward from the forward-facing air outlet section, allowing the cold air to flow farther and gradually diffuse downward, expanding the cold air coverage area. In heating mode, air is primarily delivered from the rearward-facing air outlet section, causing the warm airflow to blow toward the wall where the wall-mounted air conditioner indoor unit is located and flow more smoothly downward along the wall to better reach the ground, providing a warm foot experience.

[0041] An embodiment of the present invention provides a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit is the indoor part of a split wall-mounted room air conditioner and is used to condition indoor air, such as cooling / heating, dehumidifying, introducing fresh air, etc.

[0042] Figure 1 is a structural diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention; Figure 2 yes Figure 1 A schematic front view of a wall-mounted air conditioner indoor unit is shown; Figure 3 yes Figure 2 AA section enlarged view; Figure 4 yes Figure 3 The diagram shows a wall-mounted air conditioner indoor unit after the air guide changes the air flow direction. Arrows in the diagram indicate the direction of air flow.

[0043] like Figures 1 to 4 As shown, the wall-mounted air-conditioning indoor unit according to the embodiment of the present invention may generally include a housing 10 and an air guide device 20 .

[0044] The housing 10 defines a space for accommodating the various components of the wall-mounted air conditioner indoor unit. Airflow is generated within the housing 10 to regulate the indoor environment. Examples include cool air in cooling mode, hot air in heating mode, and fresh air in fresh air mode. The housing 10 is provided with an air outlet 12 for directing the airflow from the housing 10.

[0045] The air guide device 20 is arranged outside the air outlet 12. The air guide device 20 includes a cylinder 21, and a receiving space is defined in the cylinder 21. The peripheral wall of the cylinder 21 includes an air inlet section 211 and at least one air outlet section 212, 213 arranged along its circumference. The number of air outlet sections can be one or more. For example Figure 3 As shown, two air outlet sections 212 and 213 may be provided. The air outlet of the air outlet 12 flows through the air inlet section 211 into the interior of the cylinder 21, and then blows toward the indoor environment through at least one air outlet section 212 and 213 to adjust the indoor environment.

[0046] For example Figure 1 and Figure 2 As shown, for a wall-mounted air conditioner indoor unit, the housing 10 is usually arranged in a horizontal strip shape, that is, the length direction of the housing 10 is parallel to the horizontal direction. An air duct 60 for conveying air is provided in the housing 10. Matching this, the length direction of the cylinder 21 is parallel to the length direction of the housing 10 and is attached to the outside of the housing 10, with the air inlet section 211 located at the outlet of the air duct 60. Figure 3 As shown, the air inlet section 211 may be formed with an air inlet grille 2110 to make the structure of the cylinder 21 more stable. Of course, the air inlet section 211 may also be directly provided with an air inlet to allow the air flow to flow into the cylinder 21 more smoothly.

[0047] In the wall-mounted indoor air conditioner of the present invention, the airflow within the housing 10 is not blown directly into the indoor environment. Instead, it first enters the cylinder 21 of the air guide device 20, gathers within the cylinder 21, and is then blown outward through one or more air outlet sections 212, 213 of the cylinder 21, directing the airflow in the direction indicated by the relevant air outlet sections 212, 213. Compared to conventional wall-mounted indoor air conditioners that use air guides, the embodiment of the present invention directs the airflow direction by providing one or more air outlet sections 212, 213 on the cylinder 21, resulting in a novel and ingenious structure.

[0048] In some embodiments, as Figure 3 and Figure 4 As shown, the air guide device 20 may further include at least one air guide plate 22. The air guide plate 22 is rotatably disposed within the cylinder 21 to guide the inflow of the air inlet section 211 to different air outlet sections 212, 213 or to different areas of the same air outlet section 212, 213 by rotating to different angles.

[0049] For example Figure 3 and Figure 4 As shown, the number of air outlet sections 212 and 213 is multiple, and the multiple air outlet sections 212 and 213 are oriented in different directions. At this time, the corresponding air outlet section 212 and 213 can be selected for air supply by rotating the air guide plate 22. For example Figure 3 , so that one end (end b) of the air guide plate 22 faces the air inlet section 211, and the other end (end a) faces the air outlet sections 212, 213, 213, so that the air is mainly discharged from the air outlet section 213. Of course, it is not required that all air flows out from the air outlet section 213. There is still a small part of the air that is far away from the air guide plate 22 and is weakly guided by the air guide plate 22 or is not guided by the air guide plate 22. It will still be blown out through the remaining air outlet sections 212. This does not violate the limitations of the present invention. The air guide plate 22 can also be moved from Figure 3 Turn the position shown to Figure 4 In the position shown, one end (end a) of the air guide plate 22 faces the air inlet section 211 , and the other end (end b) faces the air outlet section 212 , so that air is mainly discharged from the air outlet section 212 .

[0050] In the embodiment of the present invention, the air guide plate 22 is hidden inside the cylinder 21. When the air guide plate 22 guides the air or rotates back and forth to swing the air, the air guide plate 22 is invisible, which subverts the appearance of the wall-mounted air conditioner indoor unit, makes the product higher-grade and provides a better user experience.

[0051] This embodiment provides two air outlet sections 212 and 213 to achieve two air supply directions. Similarly, by providing more air outlet sections, more air outlet directions can be selected. Of course, it is also possible to provide only one larger air outlet section. By rotating the air guide plate 22 to different angles, the air guide plate 22 can direct the main airflow to different areas of the air outlet section. This can also change the air supply effect. The specific structure is not shown in the figure and will not be described in detail here.

[0052] For embodiments in which multiple air outlet sections 212 and 213 are provided, the air guide device 20 can be further positioned at the lower front portion of the housing 10, so that the multiple air outlet sections 212 and 213 include at least one air outlet section 213 that discharges air forward and at least one air outlet section 212 that discharges air downward. In this way, when the wall-mounted air conditioner indoor unit is operating in cooling mode, air can be supplied forward from the forward-facing air outlet section 213, allowing the cool air to flow further and gradually diffuse downward, thus expanding the coverage area of ​​the cool air. When the wall-mounted air conditioner indoor unit is operating in heating mode, air can be supplied primarily from the downward-facing air outlet section 212, allowing the warm air to better reach the ground, achieving a warm foot experience.

[0053] In some embodiments, as Figures 1 to 3 As shown, the cylindrical body 21 can be in the shape of a triangular prism, with the three sections of its peripheral wall (i.e., the three faces of the triangular prism) forming an air inlet section 211 and two air outlet sections 212 and 213. The air guide 20 is disposed at the front lower portion of the housing 10, with one air outlet section 213 located below the front panel 101 of the housing 10, forming the front appearance of the housing 10, and the other air outlet section 212 opening toward the rear and lower portion.

[0054] In the wall-mounted air-conditioning indoor unit of the embodiment of the present invention, the cylinder 21 is in the shape of a triangular prism, which just enables its two air outlet sections 212 and 213 to face forward and backward downward, respectively. In cooling mode, air is mainly supplied outward by the air outlet section 213 facing forward, so that the cold air flows farther and gradually diffuses downward, so that the cold air covers a larger range. In heating mode, air is mainly supplied by the air outlet section 212 facing backward and downward, so that the warm air flow is blown toward the wall where the wall-mounted air-conditioning indoor unit is located, and flows downward more smoothly along the wall, forming a wall attachment effect during the flow process, which can better reach the ground along the wall to achieve a warm foot experience. Most of the existing improvement schemes choose to guide the outlet air flow vertically downward to solve the problem that hot air is not easy to sink. However, this embodiment makes the air flow blow toward the wall, and uses the wall attachment effect to make the air flow sink and flow better, and the structure is more ingenious.

[0055] For example, the triangular prism can be a regular triangular prism, with the angle between any two adjacent sections being 60 degrees. When the forward air outlet section 213 is extended vertically, the angle between the other air outlet section 212 and the vertical plane is 60 degrees. Of course, the cross-section of the triangular prism can also be a right triangle, with one air outlet section extending vertically and the other air outlet section extending horizontally, so as to be flush with the front panel 101 and the bottom wall of the housing 10, respectively, to make the appearance of the wall-mounted air conditioner indoor unit more beautiful.

[0056] When the cylinder 21 is in the shape of a triangular prism, each air guide plate 22 can be curved along the direction of the air flow so that the two ends (end a and end b) are perpendicular to the air inlet section 211 and the air outlet section 212, 213 respectively. It can be understood that when the air guide plate 22 is perpendicular to the air inlet section 211 / air outlet section 212, 213, the air flow will flow to / out of the air guide plate 22 more smoothly. Figure 3 As shown, since the air inlet section 211 and the two air outlet sections 212 and 213 are all at an acute angle (60° in the illustrated embodiment), if the air guide plate 22 is a flat plate, it will not be able to be perpendicular to the two air outlet sections 212 and 213 at the same time, which will cause the air flow to be unsmooth. To solve this problem, the present embodiment specifically makes the air guide plate 22 curved along the air flow direction, for example Figure 3 The air guide plate 22 is formed into an arc shape with a central angle of about 60° along the air flow direction, so that its two ends are perpendicular to the air inlet section 211 and the air outlet sections 212 and 213 respectively.

[0057] In some alternative embodiments, the cylinder can also be a quadrangular prism, a pentagonal prism or other multi-prism, so as to design more air outlet sections. Alternatively, the cylinder can also be cylindrical, elliptical or other shapes. Of course, the cylinder can also be other irregular shapes.

[0058] Figure 5 is an exploded schematic diagram of the air guide device 20; Figure 6 yes Figure 5 Enlarged view of point D; Figure 7 yes Figure 5 Another perspective view of the air guide plate 22 in the air guide device 20 is shown.

[0059] In some embodiments, as Figure 1 、 Figure 3 and Figure 6 As shown, the forward-facing air outlet section 213 can be provided with multiple air dispersion holes 2131, while the remaining air outlet sections 212 are formed with air outlet grilles 2122. Thus, when the wall-mounted air conditioner indoor unit operates in cooling mode and the forward-facing air outlet sections 212 and 213 are selected for air discharge, the cool air flows outward through the multiple air dispersion holes 2131, making the airflow more finely dispersed and less forceful, thus providing a more comfortable feeling for the user. The remaining air outlet sections 212 are formed with air outlet grilles 2122, providing a protective effect.

[0060] The air dispersion holes 2131 can be round, square, waist-shaped, or other shaped. The air dispersion holes 2131 can be arranged in a matrix within the air outlet sections 212 and 213. Of course, other arrangements are also possible. The air dispersion holes 2131 can be the same size and shape, or different. The air outlet grille 2122 can include a plurality of parallel, spaced-apart grille bars. Each grille bar can be fixed to the main body of the cylinder 21. Of course, each grille bar can also be rotatably mounted to the main body of the cylinder 21 so as to rotatably open and close the air outlet grille 2122 and guide the air outlet direction of the air outlet grille 2122.

[0061] In some embodiments, as Figure 1 、 Figures 5 to 7 As shown, each air guide plate 22 can be a long strip with its length parallel to the axial direction of the cylinder 21, and its rotation axis is parallel to its length. The number of air guide plates 22 can be one or more, preferably multiple, for example Figures 1 to 7 The three shown are arranged to guide more airflow. Multiple air guide plates 22 are sequentially spaced apart along the thickness direction of the air guide plate 22. One end of each of the air guide plates 22 is fixedly connected to a fixed shaft 224, and the other end of each of the air guide plates 22 is fixedly connected to another fixed shaft 224 for synchronous rotation.

[0062] In some embodiments, as Figure 5 As shown, the air guide device 20 can include two end caps 23, which are fixed to the housing 10. For example, the end caps 23 can be provided with a raised portion 2312, which is used to fit into a cavity defined in the housing 10 to position the end caps 23, and can then be fastened to the housing 10 using screws or other means. The ends of the cylinder 21 in the longitudinal direction are respectively fixed to the two end caps 23. For example, the cylinder 21 can be sleeved around the outer circumference of the end caps 23 and axially limited by the raised portion 2312. A motor 24 is disposed within one of the end caps 23.

[0063] Specifically, the end cap 23 may include an end cap body 231 with one side open and a cover 232 for sealing the end cap body 231. The end cap body 231 defines a through hole 2314, and the motor 24 is mounted within the end cap body 231. The end cap body 231 is then sealed by the cover 232. The shaft of the motor 24 extends out of the end cap 23 through the through hole 2314 to drive the air deflector 22.

[0064] like Figure 3As shown, in an embodiment of the present invention, the wall-mounted air conditioner indoor unit can be the indoor portion of a split wall-mounted room air conditioner that utilizes a vapor compression refrigeration cycle system for cooling / heating. A heat exchanger 30 and a fan 40 are provided inside the housing 10. The heat exchanger 30 and the throttling device are connected to the compressor, condenser, and other refrigeration components disposed in the air conditioner outdoor unit via pipelines, forming a vapor compression refrigeration cycle system. Under the action of the fan 40, indoor air enters the interior of the housing 10 through the air inlet 11 at the top of the housing 10, completes forced convection heat exchange with the heat exchanger 30, forms heat exchange wind, and is then blown toward the outlet of the air duct 60 under the guidance of the air duct 60, and then enters the cylinder 21. The fan 40 is preferably a cross-flow fan, which is disposed at the inlet of the air duct 60. The heat exchanger 30 is preferably a three-stage heat exchanger.

[0065] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
