Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to an indoor air conditioning unit. Background Technology

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure.

[0003] Currently, more and more people are choosing to install air conditioners indoors to regulate the temperature of the indoor air. Wall-mounted air conditioners are one type of air conditioner, and their flexible installation location, high cost-effectiveness, and wide applicability make them the first choice for most families when selecting an air conditioner.

[0004] In the existing technology, the air conditioner indoor unit opens and closes the air outlet by rotating the air guide plate. At the same time, the air guide plate guides the direction of airflow. However, when the air guide plate is open, some airflow cannot be guided by the air guide plate and is blown directly out of the air outlet, which destroys the overall guiding effect of the airflow and results in poor air delivery effect. Utility Model Content

[0005] This application discloses an indoor air conditioning unit that ensures that the airflow at the outlet of the first air duct component flows in a preset direction under the guidance of the air guide surface, thereby increasing the air delivery distance.

[0006] To achieve the above objectives, some embodiments of this application provide an indoor air conditioning unit, comprising: a casing, the casing having an air inlet and a first air outlet, and a heat exchanger disposed within the casing for exchanging heat with airflow flowing into the casing; a fan for introducing airflow into the casing through the air inlet, and after heat exchange by the heat exchanger, delivering the airflow into the room through the first air outlet; and a first ductwork component, within which a first duct is formed, the first ductwork connecting the air outlet side of the fan with the first air outlet. The first air guide is rotatably disposed at the first air outlet to open or close the first air outlet. The first air guide has a guiding surface, which is used to guide the airflow at the first air outlet to flow in a preset direction when the first air guide opens the first air outlet. The guide structure is disposed at the air outlet end of the first air duct component and is configured to guide the airflow passing through the air outlet end of the first air duct component to the guiding surface when the first air guide opens the first air outlet.

[0007] In related technologies, when the first air guide opens the first air outlet, there is a certain gap between the air outlet end of the first air guide and the front end of the air outlet end of the first air duct. When air is discharged from the first air outlet, some airflow will flow directly out from the gap between the air outlet end of the first air guide and the front end of the air outlet end of the first air duct, and cannot be blown out under the guidance of the air guide surface of the first air guide. Furthermore, this part of the airflow blown out directly will interfere with the airflow along the air guide surface of the first air guide, resulting in a short air delivery distance and poor air delivery effect.

[0008] In this embodiment, a flow guiding structure is provided at the air outlet of the first air duct component. When the first air guide component opens the first air outlet, the airflow passing through the air outlet of the first air duct component can be guided to the air guide surface of the first air guide component under the action of the flow guiding structure. This ensures that the airflow passing through the air outlet of the first air duct component (that is, the airflow blown out of the first air outlet) can be blown into the room under the guidance of the air guide surface of the first air guide component, thus ensuring the overall guiding effect of the airflow, avoiding mutual interference between airflows, and improving the air delivery distance.

[0009] In some embodiments of this application, the first air duct component includes: a first air duct wall, the first air guide component being rotatably connected to the first air duct wall; and a second air duct wall, the second air duct wall and the first air duct wall being disposed opposite each other along the front-rear direction of the housing. When the first air guide component opens the first air outlet, there is an air outlet gap between the end of the first air guide component away from the first air duct wall and the second air duct wall. At least a portion of the air guiding structure is disposed at the air outlet gap to guide the airflow passing through the air outlet gap to the air guiding surface.

[0010] In this way, the airflow exiting the first duct, upon passing through the air outlet gap, first impacts the guide structure located at the air outlet gap. The guide structure deflects the airflow that would otherwise blow directly along the air outlet gap and directs it to the guide surface of the first air guide component, which is in the open position. This allows the airflow to flow more smoothly and concentratedly along the guide surface. Guided by the guide surface, the airflow is then delivered into the room in a more concentrated state with less energy loss, along the preset airflow direction. Placing the guide structure directly at the critical point where the airflow finally exits (the air outlet gap) captures and guides the airflow, ensuring the guiding effect.

[0011] In some embodiments of this application, the flow guiding structure includes: a flow guiding rib, the flow guiding rib having a flow guiding surface, the plane of the flow guiding surface intersecting the air guiding surface; and / or, the flow guiding structure includes: a flow guiding rib, the flow guiding rib having a flow guiding surface, the flow guiding surface including a first flow guiding surface and a second flow guiding surface disposed opposite to each other, the plane of the first flow guiding surface and the plane of the second flow guiding surface both intersecting the air guiding surface.

[0012] Thus, the plane where the airflow guide surface is located intersects with the plane where the airflow guide surface of the first airflow guide is located, which means that the main flow direction of the airflow from the airflow guide surface of the airflow guide rib is preset to be towards the airflow guide surface, ensuring that the airflow can be delivered to the airflow guide surface, providing a basis for subsequent long-distance, directional air delivery.

[0013] The first and second guide surfaces mean that the guide ribs guide the airflow on both sides of the front and rear direction of the casing. The planes where the first and second guide surfaces are located intersect with the guide surface of the first air guide, so that the airflow on both sides of the guide ribs along the front and rear direction of the casing can be guided by the first and second guide surfaces. This ensures that the airflow on both sides of the guide ribs can flow to the guide surface of the first air guide under the action of the first and second guide surfaces, and then be blown into the room under the guidance of the guide surface.

[0014] In some embodiments of this application, there are multiple guide ribs, and the multiple guide ribs are spaced apart along the front-rear direction of the housing.

[0015] In this way, as the airflow passes through multiple guide ribs spaced at intervals along the front and rear direction of the casing, the airflow will pass through the first, second, and subsequent guide ribs. Each guide rib guides and organizes the airflow, adjusting its flow direction to the direction of the guide surface. No matter where the airflow is at the air outlet of the first air duct component, it can be effectively guided, avoiding the phenomenon of excessively strong or weak local airflow, resulting in a more uniform and comfortable airflow.

[0016] In some embodiments of this application, the housing includes: a front panel located at the front of the housing, and the pivot of the first air guide is disposed on the side of the first air outlet away from the front panel; the plurality of air guide ribs include: a first air guide rib, which is disposed close to the front panel in the front-rear direction of the housing, and the lower end of the first air guide rib is inclined away from the front panel relative to the upper end of the first air guide rib.

[0017] Thus, the lower end of the first guide rib is tilted away from the front panel relative to the upper end of the first guide rib, forming an inclined plane, which sets the flow direction for the airflow and guides the airflow to the air guide surface of the first air guide, ensuring that the airflow can be guided by the air guide surface of the first air guide under the action of the first guide, and realizing long-distance air delivery.

[0018] In some embodiments of this application, the first guide rib includes: a vertical section extending in a vertical direction; and an inclined section connected below the vertical section, the lower end of the inclined section being inclined relative to the upper end of the inclined section away from the front panel.

[0019] In this way, the vertical section extends vertically, allowing the airflow to transition under the guidance of the vertical section before changing its flow direction. This avoids the airflow being suddenly forced to flow towards the windward surface by the inclined section during the flow process, which would cause airflow loss. The lower end of the inclined section is inclined away from the front panel relative to the upper end, ensuring that the airflow can effectively flow towards the windward surface of the first air guide under the guidance of the inclined section.

[0020] In some embodiments of this application, the plurality of guide ribs further include: a second guide rib, the second guide rib being located on the side of the first guide rib away from the front panel, and the second guide rib extending in a vertical direction.

[0021] In this way, by setting a second guide rib extending vertically, it is ensured that the airflow blowing vertically downward can smoothly reach the air guide surface of the first air guide under the guidance of the second guide rib, and the unnecessary resistance caused by the inclined structure during the airflow process is avoided, thus ensuring the air volume.

[0022] In some embodiments of this application, when the first air guide opens the first air outlet, the first air guide can rotate between a first position and a second position, and the opening angle of the first air guide in the first position is less than the opening angle of the first air guide in the second position; when the first air guide is in the first position, the angle α between the extension line of the inclined segment and the air guide surface away from the air outlet end of the first air guide is less than 90 degrees.

[0023] Thus, setting the angle α between the extension line of the inclined section and the air guide surface away from the air outlet end of the first air guide is less than 90 degrees, which means that the angle formed between the flow direction of the airflow after passing through the inclined section and the air outlet direction of the first air guide is an obtuse angle. When the airflow after passing through the inclined section reaches the air guide surface, it can more easily flow towards the air outlet end of the first air guide (i.e., it is more easy to flow along the preset direction under the guidance of the air guide surface), avoiding the loss of air volume caused by the airflow directly impacting the air guide surface or flowing along the air guide surface to one end of the rotation axis of the first air guide, ensuring that the airflow can be blown into the room along the air guide surface of the first air guide.

[0024] In some embodiments of this application, in the vertical direction, the length L1 of the vertical segment is less than or equal to 6 mm, and the length L2 of the inclined segment is 5 mm to 10 mm.

[0025] Thus, in the vertical direction, the length L1 of the vertical section is set to be less than or equal to 6mm. This ensures sufficient guidance of the airflow while reducing flow loss caused by the airflow along the vertical section. The length L2 of the inclined section is 5mm to 10mm, ensuring that the inclined section has sufficient "operating distance" to smoothly and gradually change the airflow direction, and preventing wind pressure loss and airflow reduction caused by an excessively long inclined section L2. Through the combined effect of the lengths L1 and L2 of the vertical and inclined sections, the first guide rib becomes a compact and efficient guide component, satisfying the airflow guidance effect while reducing airflow loss.

[0026] In some embodiments of this application, the length L3 of the second guide rib is 4mm to 10mm in the vertical direction.

[0027] In this way, the second guide rib can effectively guide and rectify the airflow, while also reducing the flow loss generated when the airflow flows along the second guide rib.

[0028] In some embodiments of this application, the spacing H between two adjacent guide ribs is 7mm to 10mm.

[0029] In this way, sufficient width is ensured between two adjacent guide ribs, which can effectively prevent airflow blockage caused by excessive narrowness between two adjacent guide ribs, and ensure that multiple guide ribs can effectively guide the airflow.

[0030] In some embodiments of this application, the first air outlet is disposed at the bottom of the housing; the housing is further provided with a second air outlet, which is disposed at the top front side of the housing; the housing is further provided with a second air guide, which is rotatably disposed at the second air outlet to open or close the second air outlet.

[0031] In this way, by setting up a first air outlet and a second air outlet and independently controlling their opening and closing through the first air guide and the second air guide, the flexibility and adaptability of the air supply of the indoor unit of the air conditioner are improved, which can meet the diverse needs of users in different seasons and different scenarios.

[0058] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0059] As an important type of household appliance, air conditioners, through their indoor units, regulate indoor temperature by delivering cool air to the room, thus lowering the temperature and keeping it within a comfortable range.

[0060] In related technologies, the indoor unit of an air conditioner with downward air outlet is equipped with an air guide at the air outlet to open or close the air outlet, and the airflow blown out from the air outlet is sent into the room under the guidance of the air guide. However, when the air guide is in the open state, there is a gap between the air outlet end of the air guide and the front end of the air outlet, and some airflow will blow vertically downward from the gap and cannot be guided by the air guide, resulting in a short air delivery distance and poor air delivery effect of the airflow blown out from the air outlet.

[0061] Based on this, the present application provides an indoor air conditioning unit that can ensure that the airflow at the outlet of the first air duct component flows in a preset direction under the guidance of the air guide surface, thereby increasing the air delivery distance.

[0062] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0063] Please see Figure 1 This application provides an air conditioner indoor unit 100, which includes a casing 1. The casing 1 houses various functional components of the wall-mounted air conditioner indoor unit 100. The air conditioner indoor unit 100 in this embodiment is a wall-mounted air conditioner indoor unit (commonly also called a split-type air conditioner or wall-mounted unit). A wall-mounted air conditioner indoor unit is a type of air conditioner that is mounted on an indoor wall. It is currently the most common and widely used type of air conditioner in homes and small commercial spaces. Its advantages include: high cost-effectiveness, space saving, flexibility and convenience, and quiet operation and energy saving.

[0064] like Figure 1 and Figure 2 As shown, the housing 1 is provided with a housing air inlet 11 and a first air outlet 12. The housing air inlet 11 is used to guide airflow into the interior of the housing 1, and the airflow flows into the room through the first air outlet 12.

[0065] It should be noted that an air intake grille can be installed at the air inlet 11 of the casing to block foreign objects and dust from entering the interior of the casing 1, and to make the appearance of the indoor unit 100 of the air conditioner more neat and beautiful.

[0066] In this embodiment, the air inlet 11 is located at the top of the housing 1, and the first air outlet 12 is located at the bottom of the housing 1. Of course, the air inlet 11 can also be located on the bottom wall of the housing 1, and the first air outlet 12 can be located on the top front side of the housing 1. This embodiment does not make specific limitations on this.

[0067] like Figure 4 As shown, a heat exchanger 2 is installed inside the casing 1. The heat exchanger 2 is used to exchange heat with the airflow flowing into the casing 1. The heat exchanger 2 is a heat exchanger that utilizes the characteristic that liquid low-temperature refrigerant is easy to evaporate under low pressure. By absorbing the heat of the medium being cooled, it lowers the temperature of the surrounding air, thereby achieving a cooling effect. The cooled air after passing through the heat exchanger 2 is returned to the room through the air supply system, providing a comfortable indoor environment. Especially in the hot summer, the cooling effect of the heat exchanger 2 can significantly reduce the indoor temperature and improve people's living comfort. In this embodiment, the heat exchanger 2 is a finned heat exchanger. Of course, the heat exchanger 2 can also be other types of heat exchangers, and this embodiment does not specifically limit it.

[0068] like Figure 4 As shown, a fan 3 is also provided inside the casing 1. The fan 3 is used to introduce airflow into the casing 1 through the air inlet 11, and after heat exchange in the heat exchanger 2, the airflow is sent into the room through the first air outlet 12. The fan 3 can introduce airflow into the interior of the casing 1, so that after heat exchange in the heat exchanger 2, the airflow is sent back into the room under the action of the fan 3.

[0069] It should be noted that the fan 3 in this embodiment can be a cross-flow fan or other types of fans, and this embodiment does not make specific limitations on it.

[0070] like Figure 5 As shown, the casing 1 is also provided with a first air duct component 4, and a first air duct 41 is formed in the first air duct component 4. The first air duct 41 is used to connect the air outlet side of the fan 3 and the first air outlet 12. The airflow after heat exchange in the heat exchanger 2 flows in the first air duct 41 under the action of the fan 3, and flows along the first air duct 41 to be blown into the room from the first air outlet 12.

[0071] See Figures 3 to 5 The housing 1 also includes a first air guide 5, which is rotatably positioned at the first air outlet 12 to open or close the first air outlet 12. The first air guide 5 has a guiding surface 51, which guides the airflow at the first air outlet 12 to flow in a preset direction when the first air guide 5 opens the first air outlet 12. Through the guiding effect of the guiding surface 51 of the first air guide 5, large-angle air delivery or direct airflow to the user can be achieved.

[0072] It should be noted that the first air guide 5 is a plate-shaped structure, which is driven by a motor to rotate at the first air outlet 12.

[0073] like Figure 5 As shown, the housing 1 is also provided with a flow guiding structure 6. The flow guiding structure 6 is located at the air outlet end of the first air duct component 4. The flow guiding structure 6 is configured to guide the airflow passing through the air outlet end of the first air duct component 4 to the air guiding surface 51 of the first air guiding component 5 when the first air guide component 5 opens the first air outlet 12.

[0074] In related technologies, when the first air guide 5 opens the first air outlet 12, there will be a certain gap between the air outlet end of the first air guide 5 and the front end of the air outlet end of the first air duct 4. When air is discharged from the first air outlet 12, some airflow will flow directly out from the gap between the air outlet end of the first air guide 5 and the front end of the air outlet end of the first air duct 4, and cannot be blown out under the guidance of the air guide surface 51 of the first air guide 5. Furthermore, this part of the airflow blown out directly will interfere with the airflow along the air guide surface 51 of the first air guide 5, resulting in a short air delivery distance and poor air delivery effect.

[0075] In this embodiment, a guide structure 6 is provided at the air outlet end of the first air duct 4. When the first air outlet 12 is opened by the first air guide 5, the airflow passing through the air outlet end of the first air duct 4 can be guided to the air guide surface 51 of the first air guide 5 under the action of the guide structure 6. This ensures that the airflow passing through the air outlet end of the first air duct 4 (that is, the airflow blown out of the first air outlet 12) can be blown into the room under the guidance of the air guide surface 51 of the first air guide 5, ensuring the overall guiding effect of the airflow, avoiding mutual interference between airflows, and improving the air delivery distance.

[0076] For example, when the indoor unit 100 of the air conditioner is running, the fan 3 starts, and indoor air is drawn in from the air inlet 11 of the casing, flows through the heat exchanger 2 for heat exchange, and becomes cold or hot air. The processed airflow, driven by the fan 3, enters the first air duct 41 of the first air duct component 4 from the air outlet side of the fan 3. When the airflow reaches the air outlet of the first air duct component 4, it is effectively captured by the guide structure 6 and its direction is changed, causing it to flow towards the guide surface 51 of the opened first air guide component 5. The airflow then flows out of the first air outlet 12 close to the guide surface 51 and is sent into the room along the preset direction set by the guide surface 51, achieving efficient and long-distance air delivery.

[0077] In some embodiments, such as Figure 5 and Figure 6 As shown, the first air duct component 4 includes a first air duct wall 42, and the first air guide component 5 is rotatably connected to the first air duct wall 42. That is, the rotation axis of the first air guide component 5 is set on the first air duct wall 42, and the first air guide component 5 rotates around its rotation axis.

[0078] The first air duct component 4 also includes a second air duct wall 43. The second air duct wall 43 and the first air duct wall 42 are arranged opposite each other along the front-rear direction of the housing 1. When the first air guide component 5 opens the first air outlet 12, there is an air outlet gap N between the end of the first air guide component 5 away from the first air duct wall 42 and the second air duct wall 43. At least a portion of the air guide structure 6 is disposed at the air outlet gap to guide the airflow passing through the air outlet gap N to the air guide surface 51. That is to say, the first air duct wall 42 and the second air duct wall 43 together constitute the front and rear boundaries of the outlet portion of the first air duct 41.

[0079] When the first air guide 5 rotates to the working position of opening the first air outlet 12, there is a specific air outlet gap N between its air outlet end away from the rotating shaft (i.e., away from the first air duct wall 42) and the second air duct wall 43. Part of the airflow blown out from the air outlet side of the fan 3 passes through this air outlet gap N. In this embodiment, at least a portion of the flow guide structure 6 is provided at the air outlet gap N, so that when the airflow flows out from the first air duct 41, it will first impact the flow guide structure 6 provided at the air outlet gap N. The flow guide structure 6 deflects the airflow that was originally blown directly along the air outlet gap N and guides it to the air guide surface 51 of the first air guide 5, which is in the open position, so that the airflow can flow more smoothly and more concentratedly along the air guide surface 51. The airflow is then guided by the air guide surface 51 and sent into the room in a more concentrated state with less energy loss along the preset air supply direction. By directly placing the airflow guide structure 6 at the critical location where the airflow finally exits (air outlet gap N), it is possible to capture and redirect the airflow, ensuring the airflow guide effect.

[0080] It should be noted that the flow guiding structure 6 can be fixedly connected between the first air duct wall 42 and the second air duct wall 43, or the flow guiding structure 6 can be a separate component that can be detachably connected between the first air duct wall 42 and the second air duct wall 43 by fasteners such as screws. This embodiment does not make specific limitations on this.

[0081] In some embodiments, combined with Figure 6 and Figure 7 The flow guiding structure 6 includes a flow guiding rib 61, which has a flow guiding surface 611. The plane containing the flow guiding surface 611 intersects with the flow guiding surface 51 of the first air guide 5.

[0082] The guide surface 611 of the guide rib 61 is the main working surface on the guide rib 61 that directly contacts and guides the airflow. In this embodiment, the plane where the guide surface 611 is located intersects with the plane where the guide surface 51 of the first air guide 5 is located, which means that the main flow direction of the airflow from the guide surface 611 of the guide rib 61 is preset to be towards the guide surface 51, ensuring that the airflow can be delivered to the guide surface 51, providing a basis for subsequent long-distance, directional air delivery.

[0083] It should be noted that the guide rib 61 can be a long strip-shaped rib or plate-shaped structure, and this embodiment does not specifically limit it.

[0084] Specifically, the guide rib 61 is disposed on the side of the second air duct wall 43 facing the air outlet gap N. The guide surface 611 of the guide rib 61 can be a plane (e.g., Figure 6 As shown, it can also be a slightly curved surface. When the air guide surface 51 of the first air guide 5 is in the open state, its plane is at a certain angle to the horizontal plane. The plane of the air guide surface 611 of the guide rib 61 is at a certain angle to the horizontal plane, and the plane of the air guide surface 611 of the guide rib 61 extends in space and intersects with the air guide surface 51 along a line. The airflow at the air outlet gap N is first guided by the air guide surface 611, and after changing direction, it adheres to the air guide surface 51. Under the secondary guidance of the air guide surface 51, it is blown into the room, ensuring that the airflow at the air outlet gap N can be blown into the room under the guidance of the air guide surface 51, thus improving the air delivery distance.

[0085] It should be noted that the flow guiding structure 6 can be the flow guiding rib 61 described in the above embodiment, or it can be a porous flow guiding plate or an adjustable angle flow guiding plate. This embodiment does not make specific limitations on this.

[0086] For example, the airflow guiding structure 6 is a porous guide plate. This porous guide plate has multiple guide holes distributed on it; these holes can be round, elliptical, elongated, or other shapes. The porous guide plate is inclinedly disposed at the air outlet end of the first air duct component 4, and its inclination angle is configured to guide the airflow passing through the guide holes to the airflow guiding surface 51 of the first air guide component 5. The porous guide plate effectively disperses a concentrated airflow into multiple fine, uniform airflows and rectifys them, resulting in an extremely uniform airflow distribution that ultimately reaches the airflow guiding surface 51, avoiding the feeling of "hard wind" and improving comfort.

[0087] For example, the airflow guiding structure 6 is one or more rotatable airflow guide vanes. Each rotatable airflow guide vane is independently driven by a micro stepper motor or servo mechanism, thereby changing its angle. The rotatable airflow guide vanes are located at the air outlet end of the first air duct component 4. The control system of the air conditioning indoor unit 100 automatically adjusts the angle of the airflow guide vanes according to the current operating mode (such as cooling or heating), the angle of the first airflow guide component 5, or the user setting, to ensure that the airflow can be guided to the airflow guide surface 51 under any operating condition.

[0088] In some embodiments, such as Figure 6 As shown, the guide surface 611 includes a first guide surface 611a and a second guide surface 611b arranged opposite to each other. The plane where the first guide surface 611a is located and the plane where the second guide surface 611b is located both intersect with the guide surface 51 of the first air guide 5.

[0089] It should be noted that the first guide surface 611a and the second guide surface 611b, which are set opposite to each other, are two surfaces of the guide rib 61 that are set opposite to each other along the front and rear direction of the housing 1.

[0090] The first guide surface 611a and the second guide surface 611b mean that the guide rib 61 has a guiding effect on the airflow on both sides of the front and rear direction of the casing 1. The plane where the first guide surface 611a and the plane where the second guide surface 611b are located intersect with the air guide surface 51 of the first air guide 5, so that the airflow on both sides of the guide rib 61 in the front and rear direction of the casing 1 can be guided by the first guide surface 611a and the second guide surface 611b. This ensures that the airflow on both sides of the guide rib 61 can flow to the air guide surface 51 of the first air guide 5 under the action of the first guide surface 611a and the second guide surface 611b, and then be blown into the room under the guidance of the air guide surface 51.

[0091] It should be noted that the first guide surface 611a and the second guide surface 611b can be arc surfaces or inclined planes, and this embodiment does not make specific limitations on this.

[0092] In some embodiments, combined with Figure 6 and Figure 7 There are multiple guide ribs 61, and the multiple guide ribs 61 are arranged at intervals along the front and rear direction of the housing 1.

[0093] Specifically, the multiple guide ribs 61 can be arranged in a parallel manner. For example, the multiple guide ribs 61 can all be disposed at the air outlet gap N. Each guide rib 61 is along the length direction of the first air outlet 12 (e.g., Figure 3 They extend from left to right or right to left in the direction of the flow, thus forming a flow guide array.

[0094] When airflow exits from the first air duct 41, its flow direction may not be uniform. As the airflow passes through multiple guide ribs 61 spaced along the front-rear direction of the casing 1, it will pass through the first, second, and subsequent guide ribs 61. Each guide rib 61 guides and organizes the airflow, adjusting its flow direction to the direction of the guide surface 51. Regardless of the position of the airflow at the outlet of the first air duct component 4, it can be effectively guided, avoiding the phenomenon of excessively strong or weak local airflow, resulting in a more uniform and comfortable final airflow.

[0095] It should be noted that the number of guide ribs 61 can be two, three, four, or more; this embodiment does not specifically limit this. In this embodiment, as... Figure 6 As shown, the number of guide ribs 61 is five.

[0096] It should be noted that the multiple guide ribs 61 are connected by multiple connecting plates to ensure the structural strength and stability of the multiple guide ribs 61.

[0097] In some embodiments, combined with Figure 1 and Figure 5 The housing 1 includes a front panel 13, which is located on the front side of the housing 1. The pivot of the first air guide 5 is located on the side of the first air outlet 12 away from the front panel 13. That is to say, when the first air guide 5 opens the first air outlet 12, the opening of the first air guide 5 faces the front panel 13. The front panel 13 constitutes the main appearance surface of the housing 1 facing the user in the indoor space, and usually adopts an aesthetic and neat design.

[0098] The plurality of guide ribs 61 include a first guide rib 612. In the front-rear direction of the housing 1, the first guide rib 612 is disposed close to the front panel 13, and the lower end of the first guide rib 612 is inclined away from the front panel 13 relative to the upper end of the first guide rib 612.

[0099] The lower end of the first guide rib 612 is tilted away from the front panel 13 relative to the upper end of the first guide rib 612, forming an inclined plane, which sets the flow direction for the airflow and guides the airflow to the air guide surface 51 of the first air guide 5. This ensures that the airflow can be guided by the air guide surface 51 of the first air guide 5 under the action of the first guide rib 612, thereby achieving long-distance air delivery.

[0100] It should be noted that the first guide rib 612 can be an inclined plate structure or an arc-shaped plate structure, as long as it can guide the airflow to the air guide surface 51 of the first air guide 5. This embodiment does not make specific limitations on this.

[0101] In some embodiments, such as Figure 6 As shown, the first guide rib 612 includes a vertical section 6121, which extends in the vertical direction.

[0102] The first guide rib 612 also includes an inclined section 6122, which is connected to the lower part of the vertical section 6121. The lower end of the inclined section 6122 is inclined away from the front panel 13 relative to the upper end of the inclined section 6122.

[0103] In other words, the first guide rib 612 is not an inclined plate structure, but is composed of a vertical section 6121 and an inclined section 6122. When the airflow passes through the first guide rib 612, the airflow first flows along the vertical section 6121, then along the vertical section 6121 to the inclined section 6122, and then along the inclined section 6122 to the air guide surface 51 of the first air guide 5.

[0104] It should be noted that in this embodiment, the first air duct 41 extends in a vertical direction, that is, the airflow direction before flowing to the first guide rib 612 is downward in a vertical direction.

[0105] The vertical section 6121 extends vertically, allowing the airflow to transition under its guidance before changing direction. This prevents airflow loss caused by the airflow being suddenly forced to flow towards the guide surface 51 by the inclined section 6122. The lower end of the inclined section 6122 is inclined away from the front panel 13 relative to its upper end, ensuring that the airflow effectively flows towards the guide surface 51 of the first guide element 5 under the guidance of the inclined section 6122.

[0106] It should be noted that the connection between the vertical section 6121 and the inclined section 6122 can be a one-piece molding transition, or it can be fixed by welding, snap-fitting, or other methods. This embodiment does not make specific limitations on this.

[0107] It should be noted that, in addition to being directly connected, the vertical section 6121 and the inclined section 6122 can also be connected by a smooth transition arc surface. This smooth transition can further reduce the resistance of the airflow passing through this point and prevent the airflow from generating vortices during the process of flowing from the vertical section 6121 to the inclined section 6122.

[0108] In some embodiments, combined with Figure 5 and Figure 6 The plurality of guide ribs 61 also include a second guide rib 613, which is located on the side of the first guide rib 612 away from the front panel 13 and extends in a vertical direction.

[0109] When the first air guide 5 opens the first air outlet 12, the airflow within the air outlet gap N will be blown out directly, while the remaining airflow at the outlet end of the first air duct 4 will first flow onto the air guide surface 51 of the first air guide 5, and then be blown out under the guidance of the air guide surface 51. Therefore, for airflow outside the air outlet gap N, there is no need to set an inclined structure to guide the airflow to the air guide surface 51 of the first air guide 5. Therefore, in this embodiment, by setting a second guide rib 613 extending in the vertical direction, it is ensured that the vertically downward blowing airflow can smoothly reach the air guide surface 51 of the first air guide 5 under the guidance of the second guide rib 613, and the unnecessary resistance caused by the inclined structure during the airflow process is avoided, thus ensuring the air volume.

[0110] It should be noted that the second guide rib 613 can be set with some specific surface textures to further optimize the rectification effect and aerodynamic performance of the second guide rib 613.

[0111] In some embodiments, combined with Figure 5 and Figure 8 When the first air guide 5 opens the first air outlet 12, the first air guide 5 can rotate between the first position and the second position, and the opening angle of the first air guide 5 in the first position (e.g.) Figure 5 (As shown) is less than the opening angle of the first air guide 5 in the second position (e.g.) Figure 8 (As shown).

[0112] It should be noted that when the first air guide 5 opens the first air outlet 12, the first air guide 5 can rotate within a certain angle to expand the air supply range of the indoor unit 100 of the air conditioner. The first position of the first air guide 5 is the position where the opening angle of the first air guide 5 is the smallest (e.g., Figure 5 As shown), the second position of the first air guide 5 is the position where the first air guide 5 opens to its maximum angle (as shown). Figure 8 (As shown).

[0113] like Figure 6 As shown, when the first air guide 5 is in the first position, the angle α between the extension line of the inclined section 6122 and the air guide surface 51 away from the air outlet end of the first air guide 5 is less than 90 degrees. The size of the angle between the extension line of the inclined section 6122 and the air guide surface 51 away from the air outlet end of the first air guide 5 determines the flow direction of the airflow after it reaches the air guide surface 51 of the first air guide 5 under the action of the inclined section 6122.

[0114] If the angle α between the extension line of the inclined section 6122 and the air guide surface 51 and the air outlet end of the first air guide 5 is 90 degrees, it means that the airflow guided by the inclined section 6122 will directly and vertically impact the air guide surface 51 of the first air guide 5, causing this part of the airflow to be unable to be blown into the room along the air guide surface 51, resulting in airflow loss.

[0115] If the angle α between the extension line of the inclined section 6122 and the air guide surface 51 away from the air outlet end of the first air guide 5 is greater than 90 degrees, it means that the angle formed between the flow direction of the airflow guided by the inclined section 6122 and the air outlet direction of the air guide surface 51 is an acute angle. At this time, the airflow guided by the inclined section 6122 is not easy to flow to the air outlet end of the first air guide 5 after reaching the air guide surface 51. Instead, it is easier to flow along the air guide surface 51 to one end of the rotation axis of the first air guide 5. This causes the airflow guided by the inclined section 6122 to collide with the other airflow on the air guide surface 51, resulting in a reduction in the amount of air blown out of the first air outlet 12.

[0116] Therefore, in this embodiment, the angle α between the extension line of the inclined section 6122 and the air guide surface 51 away from the air outlet end of the first air guide 5 is less than 90 degrees. This means that the angle formed between the flow direction of the airflow after being guided by the inclined section 6122 and the air outlet direction of the first air guide 5 is an obtuse angle. When the airflow after being guided by the inclined section 6122 reaches the air guide surface 51, it can more easily flow towards the air outlet end of the first air guide 5 (i.e., it is more easy to flow along the preset direction under the guidance of the air guide surface 51). This avoids the loss of airflow caused by the airflow directly impacting the air guide surface 51 or flowing along the air guide surface 51 towards one end of the rotation axis of the first air guide 5, ensuring that the airflow can be blown into the room along the air guide surface 51 of the first air guide 5.

[0117] It should be noted that, as Figure 6 As shown, there can be two first guide ribs 612. The angles between the two first guide ribs 612 and the vertical direction are different. The angle β between one of the two first guide ribs 612 and the vertical direction is 30 degrees to 40 degrees, and the angle γ between the other of the two first guide ribs 612 and the vertical direction is 15 degrees to 20 degrees. Because the distance between the two first guide ribs 612 and the air guiding surface 51 of the first air guiding component 5 is different when the first air guiding component 5 is opened, the angles between the two first guide ribs 612 and the vertical direction are different. This is to ensure that the airflow can effectively flow to the air guiding surface 51 of the first air guiding component 5 under the guidance of the two first guide ribs 612, and can flow smoothly along the air guiding surface 51 of the first air guiding component 5 to the air outlet end of the first air guiding component 5.

[0118] For example, one of the two first guide ribs 612 has an angle β of 33 degrees with the vertical direction, and the other of the two first guide ribs 612 has an angle γ of 20 degrees with the vertical direction. In this case, the airflow is more effectively guided to the air guide surface 51 of the first air guide 5 under the guidance of the two first guide ribs 612.

[0119] In some embodiments, such as Figure 6 As shown, in the vertical direction, the length L1 of the vertical segment 6121 is less than or equal to 6 mm, and the length L2 of the inclined segment 6122 is 5 mm to 10 mm.

[0120] If the length L1 of the vertical section 6121 is greater than 6mm, it means that the airflow will travel too far under the action of the vertical section 6121. The guiding effect of the vertical section 6121 on the airflow is formed by the airflow adhering to the surface of the vertical section 6121. The airflow will generate friction with the vertical section 6121. If the airflow travels too far under the action of the vertical section 6121, it will cause more friction between the airflow and the surface of the vertical section 6121, resulting in more airflow loss.

[0121] Therefore, in the vertical direction, the length L1 of the vertical section 6121 is set to be less than or equal to 6mm. This ensures that the vertical section 6121 has sufficient guiding effect on the airflow while reducing the flow loss caused by the airflow flowing along the vertical section 6121.

[0122] If the length L2 of the inclined section 6122 is greater than 10mm, it means that the length of the inclined section 6122 is too long and the lower end of the inclined section 6122 occupies too much flow area of ​​the first air outlet 12, which will cause wind pressure loss and air volume reduction.

[0123] If the length L2 of the inclined section 6122 is less than 5mm, it means that the length of the inclined section 6122 is too short, the guiding distance of the inclined section 6122 is too short, the change of airflow direction will be too drastic, which will easily lead to airflow separation, eddies and noise, thus weakening the guiding effect of the inclined section 6122 on the airflow.

[0124] Therefore, in the vertical direction, the length L2 of the inclined section 6122 is 5mm to 10mm, ensuring that the inclined section 6122 has sufficient "operating distance" to smoothly and gradually change the airflow direction, and preventing wind pressure loss and airflow attenuation caused by excessive length of the inclined section 6122. Through the combined effect of the length L1 of the vertical section 6121 and the length L2 of the inclined section 6122, the first guide rib 612 becomes a compact and efficient guide component, which satisfies the airflow guiding effect while reducing airflow loss.

[0125] It should be noted that the length L1 of the vertical segment 6121 can be 1mm, 2mm, 3mm, 4mm, 5mm or 6mm, and the length L2 of the inclined segment 6122 can be 5mm, 6mm, 7mm, 8mm, 9mm or 10mm. This embodiment does not make specific limitations on these.

[0126] For example, the length L1 of the vertical section 6121 is 5mm and the length L2 of the inclined section 6122 is 8mm. At this time, the first guide rib 612 formed by the vertical section 6121 and the inclined section 6122 maintains a balance in terms of guide efficiency and air volume retention.

[0127] In some embodiments, such as Figure 6 As shown, in the vertical direction, the length L3 of the second guide rib 613 is 4mm to 10mm.

[0128] If the length L3 of the second guide rib 613 is greater than 10mm, it means that the length of the second guide rib 613 is too long. When the airflow flows along the second guide rib 613, more flow loss will occur, resulting in a reduction in air volume.

[0129] If the length L3 of the second guide rib 613 is less than 4mm, it means that the length of the second guide rib 613 is too short. The distance that the airflow travels along the second guide rib 613 will be shorter, which will cause the second guide rib 613 to be unable to effectively guide and rectify the airflow.

[0130] Therefore, in this embodiment, the length L3 of the second guide rib 613 in the vertical direction is set to be 4mm to 10mm, which ensures that the second guide rib 613 can effectively guide and rectify the airflow, and also reduces the flow loss generated when the airflow flows along the second guide rib 613.

[0131] It should be noted that, in the vertical direction, the length L3 of the second guide rib 613 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm, and this embodiment does not make a specific limitation on this.

[0132] For example, in the vertical direction, the length L3 of the second guide rib 613 is 5mm. In this case, the second guide rib 613 has a more significant effect on guiding and rectifying the airflow, while having a smaller negative impact on the air volume and air pressure.

[0133] In some embodiments, such as Figure 6 As shown, the spacing H between two adjacent guide ribs 61 is 7mm to 10mm. The spacing between two adjacent guide ribs 61 is related to the air volume at the outlet end of the first air duct component 4.

[0134] It should be noted that the spacing H between two adjacent guide ribs 61 refers to the straight-line distance between corresponding points (such as the center line or corresponding edge) of two adjacent guide ribs 61 in the front-back direction of the housing 1.

[0135] If the distance H between two adjacent guide ribs 61 is greater than 10mm, it means that the distance between two adjacent guide ribs 61 is too large. The airflow between the two guide ribs 61 may not be effectively guided and may be easily lost locally or form uncontrolled vortices, thereby weakening the rectification effect of multiple guide ribs 61, resulting in a decrease in air supply uniformity and an increase in wind noise.

[0136] If the distance H between two adjacent guide ribs 61 is less than 7mm, it means that the distance between two adjacent guide ribs 61 is too small. When the airflow passes between the two adjacent guide ribs 61, the airflow will be blocked due to the narrow channel, resulting in excessive wind pressure loss and high-frequency whistling sound.

[0137] Therefore, in this embodiment, by setting the spacing H between two adjacent guide ribs 61 to 7mm to 10mm, it is ensured that there is sufficient width between two adjacent guide ribs 61, which can effectively prevent airflow blockage caused by the narrow gap between two adjacent guide ribs 61, and ensure that multiple guide ribs 61 can effectively guide the airflow.

[0138] It should be noted that the spacing H between two adjacent guide ribs 61 can be 7mm, 8mm, 9mm or 10mm, and this embodiment does not make a specific limitation on this.

[0139] For example, the spacing H between two adjacent guide ribs 61 is 8mm. While ensuring the guiding and rectification performance, it reduces the noise level generated by the airflow passing between the two adjacent guide ribs 61, thus achieving a balance between the guiding effect and the noise reduction level of multiple guide ribs 61.

[0140] In some embodiments, such as Figure 8 As shown, the first air outlet 12 is located at the bottom of the casing 1. The airflow blowing out from the first air outlet 12 is vertically downward, and the airflow is blown into the room in a preset direction under the action of the air guide surface 51 of the first air guide 5, so as to meet the user's air supply needs.

[0141] like Figure 9 As shown, the housing 1 is also provided with a second air outlet 14, which is located on the top front side of the housing 1. That is to say, the second air outlet 14 is located in the upper area of ​​the front panel 13 of the housing 1, and supplies air to the upper front of the room.

[0142] The housing 1 also includes a second air guide 7, which is rotatably mounted on the second air outlet 14 to open or close the second air outlet 14. Specifically, the second air guide 7 has a plate-like structure, and its shaft is rotatably mounted on the second air outlet 14. By driving it to rotate using a drive device (such as a stepper motor), the second air outlet 14 can be opened or closed. When the second air guide 7 opens the second air outlet 14, it can also guide the airflow in a specific direction.

[0143] The indoor unit 100 of the air conditioner has multiple air supply modes through the first air outlet 12 and the second air outlet 14. When the first air guide 5 closes the first air outlet 12 and the second air guide 7 opens the second air outlet 14, the indoor unit 100 of the air conditioner operates in the top air outlet mode (e.g., ...). Figure 9As shown), all airflow is delivered through the second air outlet 14 at the top. In cooling mode, denser cold air naturally sinks, and airflow from the top forward achieves a gentle, imperceptible breeze, evenly distributing cool air throughout the room from top to bottom, improving user comfort. When the second air guide 7 closes the second air outlet 14 and the first air guide 5 opens the first air outlet 12, the indoor unit 100 operates in down-discharge mode (e.g., ...). Figure 8 As shown), all the airflow generated by the fan is sent out through the first air outlet 12, and the airflow direction is controlled by the first air guide 5. This mode is suitable for rapid heating or anti-direct-blow cooling. When the first air guide 5 opens the first air outlet 12 and the second air guide 7 opens the second air outlet 14, the indoor unit 100 of the air conditioner operates in the up-and-down airflow mode (as shown). Figure 10 As shown, the airflow is split into two paths, simultaneously exiting from the second air outlet 14 at the top and the first air outlet 12 at the bottom. This mode enables rapid room temperature regulation and strong air agitation, making it suitable for scenarios requiring rapid cooling or heating. By setting the first air outlet 12 and the second air outlet 14 and independently controlling their opening and closing via the first air guide 5 and the second air guide 7, the flexibility and adaptability of the air supply of the indoor air conditioning unit 100 are improved, meeting the diverse needs of users in different seasons and scenarios.

[0144] It should be noted that a component similar to the airflow guide structure 6 can also be installed at the second air outlet 14 to optimize the airflow effect of the second air outlet 14.

[0145] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
