Description

Technical Field

[0001] This application relates to the field of home appliance technology, such as an air conditioner cabinet unit. Background Technology

[0002] For over a century since its invention, air conditioning has primarily employed traditional mixed ventilation or displacement ventilation for ventilation. Mixed ventilation aims to eliminate the entire indoor load, using mechanical force to drive airflow. The supplied air mixes strongly with the indoor air, achieving a uniform distribution of temperature and humidity across the entire room, but with lower temperature efficiency. Displacement ventilation primarily aims to eliminate a portion of the load, i.e., the heating or cooling load of the work area, ensuring the comfort or production requirements of those served. Thermal buoyancy and mechanical force have a synergistic effect, resulting in less intense mixing of indoor air and higher temperature efficiency.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] In both ventilation systems, cold and hot air are discharged through the same air outlet, which cannot meet the different air blowing needs during heating and cooling. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides an air conditioning unit that combines the advantages of both mixed ventilation and displacement ventilation, thereby meeting the different airflow needs of users in heating and cooling modes and improving the user experience.

[0007] In some embodiments, the air conditioner cabinet unit includes: a housing, a first air duct, a second air duct, and an air duct sealing assembly. An air cavity is provided inside the housing; the first air duct communicates with the air cavity and discharges air downwards; the second air duct communicates with the air cavity and surrounds part or all of the outer side of the first air duct, discharging air circumferentially; the air duct sealing assembly is capable of opening one of the first and second air ducts while simultaneously closing the other.

[0008] The air conditioner unit provided in this embodiment can achieve the following technical effects:

[0009] The air conditioner is equipped with two downward-facing air outlet ducts. Hot and cold air are blown out from different ducts. The airflow from one duct flows downward along the vertical wall of the air conditioner unit. After hitting the ground, the airflow spreads outwards around the lower side of the air conditioner, creating an "air lake" effect on the ground, where low-speed, small-temperature-difference airflow is evenly diffused along the floor. The other duct evenly discharges air outwards, which can accelerate the mixing with indoor air. This combines the advantages of both mixed ventilation and displacement ventilation, meeting the different airflow needs of users in heating and cooling modes and improving the user experience.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] Combination Figure 1-5 As shown, this embodiment of the present disclosure provides an air conditioning unit, including: a housing 100, a first air duct 200, a second air duct 300, and an air duct sealing assembly 400. The housing 100 defines an air outlet cavity 101; the first air duct 200 communicates with the air outlet cavity 101 and discharges air downwards; the second air duct 300 communicates with the air outlet cavity 101 and surrounds part or all of the outer side of the first air duct 200, discharging air circumferentially; the air duct sealing assembly 400 is capable of opening one of the first air duct 200 and the second air duct 300 while simultaneously closing the other.

[0040] The air conditioning unit provided in this embodiment has two downward-facing air outlet ducts. Hot air and cold air are blown out from different ducts. The airflow from one duct flows downward against the vertical wall of the air conditioning unit. After hitting the ground, the airflow spreads outwards around the lower side of the air conditioner, creating an effect similar to an "air lake" on the ground, where low-speed, small-temperature-difference airflow spreads evenly along the floor. The other duct evenly discharges air outwards, which can accelerate the mixing with indoor air. This combines the advantages of both mixed ventilation and displacement ventilation, meeting the different airflow needs of users in heating and cooling modes and improving the user experience.

[0041] Optionally, a first guide member 500 is provided on the outer periphery of the first air duct 200. The first guide member 500 includes an arc-shaped guide surface and is curved toward the outer periphery of the second air duct 300, which can guide the airflow from the second air duct 300. In this way, the airflow from the second air duct 300 can diffuse into the room along the arc-shaped guide surface, so that the first guide member 500 can guide the airflow from the second air duct 300. This allows the airflow from the second air duct 300 to be evenly discharged around the periphery under the guidance of the first guide member 500, which can accelerate the mixing with the indoor air. Furthermore, the arc-shaped guide surface can make the airflow process more stable, prevent the airflow from becoming too turbulent, and improve the stability of the airflow process.

[0042] Optionally, the first air guide 500 extends downward along the middle of the first air duct 200 and the second air duct 300, and includes a first air guide surface capable of guiding the airflow from the second air duct 300. Since the second air duct 300 is oriented downwards and discharges air circumferentially, extending the first air guide 500 downwards adapts its installation to the airflow direction of the second air duct 300. This allows the first air guide 500 to guide the airflow from the second air duct 300, resulting in uniform airflow around the perimeter under the guidance of the first air guide 500. This accelerates mixing with indoor air, meets different user ventilation needs, and improves the user experience.

[0043] Optionally, a second air guide 600 is provided below the first air duct 200 to guide the airflow from the first air duct 200. In this way, under the guidance of the second air guide 600, the airflow from the first air duct 200 adheres to the vertical wall of the air conditioner unit and flows downward. After the airflow hits the ground, it spreads out around the lower side of the air conditioner, forming an effect similar to an "air lake" on the ground. That is, the airflow with low wind speed and small temperature difference is evenly diffused along the floor, resulting in high air supply temperature efficiency.

[0044] Optionally, the second guide member 600 includes a downwardly inclined guide surface. In this way, the airflow from the first air duct 200 flows through the air outlet channel of the first air duct 200 formed by the connection between the first guide member 500 and the side wall of the air duct section 104 to the second guide member 600. This ensures that the airflow from the first air duct 200 is only discharged in the area corresponding to the second guide surface. The downwardly inclined guide surface allows the second guide surface to guide the airflow from the first air duct 200, enabling the airflow from the first air duct 200 to adhere to the vertical wall of the air conditioner unit and flow downwards. After impacting the ground, the airflow diffuses outwards towards the lower perimeter of the air conditioner, creating an effect similar to an "air lake" on the ground. This means that the low-velocity, small-temperature-difference airflow diffuses evenly along the floor, resulting in high air supply temperature efficiency.

[0045] Optionally, the first air duct 200 is a hot air duct, and the second air duct 300 is a cold air duct. Thus, due to the guiding effect of the second guide element 600, the airflow from the first air duct 200 flows downwards along the vertical wall of the air conditioner unit. After impacting the ground, the airflow spreads outwards around the lower side of the air conditioner, creating an effect similar to an "air lake" on the ground. Therefore, the first air duct 200 is used as a heating air duct. In winter, hot air is blown out from the first air duct 200, and under the guiding effect of the second guide element 600, the hot air can create an effect similar to an "air lake" on the ground. That is, the low-velocity, small-temperature-difference airflow is evenly diffused along the floor, resulting in high air supply temperature efficiency. The hot air blows downwards to warm the feet, improving user comfort. Secondly, because the airflow from the second air duct 300 is evenly distributed around the perimeter under the guidance of the first guide element 500, it can accelerate the mixing with indoor air. Therefore, the second air duct 300 is used as a cooling air duct. In summer, cold air is blown out from the second air duct 300, and the cold air is evenly distributed around the perimeter under the guidance of the first guide element 500, accelerating the mixing with indoor air, thereby rapidly lowering the indoor temperature, making users feel cooler, and improving user comfort. In addition, by designing the air outlets of the first air duct 200 and the second air duct 300, the cooling / heating modes are delivered from different air ducts, improving user comfort.

[0046] Optionally, the housing 100 includes a lower housing portion 102, an upper housing portion 103, and an air duct portion 104. The air duct portion 104 connects the interior of the lower housing portion 102 and the interior of the upper housing portion 103, and connects to a portion of the upper end of the lower housing portion 102 and a portion of the lower end of the upper housing portion 103. This ensures that the airflow within the lower housing portion 102 can stably enter the upper housing portion 103 through the air duct portion 104. Furthermore, since the air duct portion 104 connects a portion of the upper end face of the lower housing portion 102 and a portion of the lower end face of the upper housing portion 103, it reduces the space occupied by the air duct portion 104 on the upper end face of the lower housing portion 102 and the lower end face of the upper housing portion 103. This facilitates the arrangement of the first air duct 200 and the second air duct 300, as well as the installation of the first guide member 500 and the second guide member 600, thereby facilitating the rational design of the first air duct 200 and the second air duct 300. The installation positions of the first air guide 500 and the second air guide 600 allow the airflow from the first air duct 200 to flow downwards along the vertical wall of the air conditioner unit under the guidance of the second air guide 600. After the airflow hits the ground, it spreads outwards to the lower perimeter of the air conditioner, forming an effect similar to an "air lake" on the ground. This allows the airflow from the second air duct 300 to be evenly distributed to the perimeter under the guidance of the first air guide 500, accelerating the mixing with indoor air. This results in higher air supply temperature efficiency for the air conditioner unit, while also reducing costs and saving energy.

[0047] Optionally, there is a set distance between the first guide member 500 and the second guide member 600. This allows the airflow from the first air duct 200 to flow out between the first guide member 500 and the second guide member 600 as it flows downward. Under the guidance of the second guide member 600, the airflow adheres to the vertical wall of the air conditioner unit and flows downward. After hitting the ground, the airflow spreads out around the lower side of the air conditioner, forming an effect similar to an "air lake" on the ground. This means that the low-speed, small-temperature-difference airflow is evenly diffused along the floor, resulting in high air supply temperature efficiency.

[0048] Optionally, the sum of the height of the first guide member 500, the height of the second guide member 600, and the set distance is equal to the distance between the lower shell 102 and the upper shell 103. This design facilitates the first air guide 500 to guide the airflow from the second air duct 300 into the room stably and quickly, preventing excessive airflow turbulence and ensuring more uniform diffusion of the airflow into the room. This improves the stability of the airflow process, resulting in higher air supply temperature efficiency for the air conditioning unit. It also facilitates the stable and rapid guidance of the airflow from the first air duct 200 to the second air guide 600, allowing the airflow from the first air duct 200 to flow downwards between the first air guide 500 and the second air guide 600. Under the guidance of the second air guide 600, the airflow from the first air duct 200 adheres to the vertical wall of the air conditioning unit and flows downwards. After impacting the ground, the airflow diffuses outwards around the lower side of the air conditioner, creating an "air lake" effect on the ground. This low-velocity, low-temperature-difference airflow diffuses evenly along the floor, resulting in high air supply temperature efficiency while reducing costs and saving energy.

[0049] Optionally, the height of the first guide element 500 is greater than the height of the second guide element 600. For example, the height of the first guide element 500 is twice the height of the second guide element 600. This allows the first guide element 500 to guide the airflow from the second air duct 300 while simultaneously and stably and quickly directing the airflow from the first air duct 200 to the second guide element 600. This prevents the airflow from the first air duct 200 from wandering around during its flow to the second guide element 600, improving the stability of the airflow process. Consequently, under the guidance of the second guide element 600, the airflow from the first air duct 200 adheres to the vertical wall of the air conditioner unit and flows downwards. After impacting the ground, the airflow spreads outwards around the lower side of the air conditioner, creating an "air lake" effect on the ground, resulting in high air supply temperature efficiency.

[0050] Optionally, the height of the second guide element 600 is greater than the set distance. For example, the height of the second guide element 600 is twice the set distance. This allows the airflow from the first duct 200 to flow downwards through the set distance between the first guide element 500 and the second guide element 600, and the set distance is less than the height of the second guide element 600. This ensures that the set distance is within a reasonable range, guaranteeing that the airflow from the first duct 200 is fully guided by the second guide element 600. Consequently, under the guidance of the second guide element 600, the airflow from the first duct 200 adheres to the vertical wall of the air conditioner unit and flows downwards. After impacting the ground, the airflow spreads outwards around the lower side of the air conditioner, creating an effect similar to an "air lake" on the ground. This means that the low-velocity, small-temperature-difference airflow diffuses evenly along the floor, resulting in high air supply temperature efficiency.

[0051] It is worth noting that the height of the first guide element 500 refers to the length of the first guide element 500 extending downwards along the middle position of the first air duct 200 and the second air duct 300.

[0052] Optionally, the second air duct 300 is partially surrounding the outer periphery of the first air duct 200. In this way, the second air duct 300 and the first air duct 200 only discharge air within their respective corresponding air outlet areas, enhancing the air supply effect. Specifically, the airflow from the second air duct 300 flows towards the first guide element 500, and the second air duct 300 only discharges air within the area corresponding to the first guide surface. This allows the first guide surface to guide the airflow from the second air duct 300, enabling the airflow from the second air duct 300 to be evenly distributed around the periphery, accelerating mixing with indoor air. Meanwhile, the airflow from the first air duct 200... The airflow flows to the second guide element 600, and the first air duct 200 only discharges air in the area corresponding to the second guide surface. This allows the second guide surface to guide the airflow from the first air duct 200, which in turn allows the airflow from the first air duct 200 to adhere to the vertical wall of the air conditioner unit and flow downwards. After the airflow hits the ground, it spreads out to the lower perimeter of the air conditioner, forming an effect similar to an "air lake" on the ground. This means that the low-speed, small-temperature-difference airflow is evenly diffused along the floor, resulting in high air supply temperature efficiency.

[0053] Optionally, the second air duct 300 surrounds the outer periphery of the first air duct 200, except for the side closest to the air duct section 104. This ensures that the second air duct 300 and the first air duct 200 only discharge air within the areas of their respective first and second guide surfaces. This allows the first guide surface to guide the airflow from the second air duct 300, and the second guide surface to guide the airflow from the first air duct 200. Consequently, the second air duct 300 and the first air duct 200 can deliver air to the room according to the user's needs, resulting in higher airflow temperature efficiency and enhanced airflow effect.

[0054] Optionally, the second air duct 300 has a U-shaped structure. This allows the second air duct 300 to discharge air from three sides, and under the guidance of the first guide element 500, the airflow from the second air duct 300 can be discharged stably, quickly, and evenly around the perimeter, which can accelerate the mixing with indoor air, enhance the air supply effect, and has a high air supply temperature efficiency.

[0055] Optionally, the second air duct 300 includes a first air outlet 301, a second air outlet 302, and a third air outlet 303. The first air outlet 301 is located on the side opposite to the second air outlet 302, and the third air outlet 303 connects the first air outlet 301 and the second air outlet 302, and the first air outlet 301, the second air outlet 302, and the third air outlet 303 together enclose the first air duct 200. Thus, the second air duct 300 consists of three air outlets. Air is discharged through the first air outlet 301, the second air outlet 302, and the third air outlet 303. Under the guidance of the first guide member 500, the first air outlet 301, the second air outlet 302, and the third air outlet 303 can discharge air to different directions within the room, accelerating mixing with indoor air, enhancing the air supply effect, and achieving high air supply temperature efficiency. Furthermore, the three air outlets together enclose the first air duct 200. The airflow from the first air duct 200 flows to the second guide element 600. The first air duct 200 only discharges air in the area corresponding to the second guide surface, so that the second guide surface can guide the airflow from the first air duct 200. This allows the airflow from the first air duct 200 to adhere to the vertical wall of the air conditioner unit and flow downwards. After the airflow hits the ground, it spreads out to the lower perimeter of the air conditioner, forming an effect similar to an "air lake" on the ground. That is, the airflow with low wind speed and small temperature difference spreads evenly along the floor, resulting in high air supply temperature efficiency.

[0056] Optionally, the first guide member 500 includes: a first guide portion 501, a second guide portion 502, and a third guide portion 503. One end of the first guide portion 501 is fixed between the first air outlet 301 and the first air duct 200, and the other end extends downward; one end of the second guide portion 502 is fixed between the second air outlet 302 and the first air duct 200, and the other end extends downward; one end of the third guide portion 503 is fixed between the third air outlet 303 and the first air duct 200, and the other end extends downward, and the third guide portion 503 connects the first guide portion 501 and the second guide portion 502. In this way, the first guide section 501, the second guide section 502, and the third guide section 503 are respectively arranged to correspond to the first air outlet 301, the second air outlet 302, and the third air outlet 303, so that the airflow from the first air outlet 301, the second air outlet 302, and the third air outlet 303 can be directed to different directions in the room under the guidance of the first guide section 501, the second guide section 502, and the third guide section 503, ensuring that the airflow flows stably and evenly to different directions in the room, with high air supply temperature efficiency, further enhancing the air supply effect.

[0057] Optionally, the first guide section 501, the second guide section 502, and the third guide section 503 form a guide structure arranged on three sides. In this way, the airflow from the second air duct 300 flows towards the first guide section 500, and the second air duct 300 only discharges air in the area corresponding to the first guide surface. This allows the first guide surface to guide the airflow from the second air duct 300, so that the airflow from the first air outlet 301, the second air outlet 302, and the third air outlet 303 can be discharged to different directions in the room under the guidance of the first guide section 501, the second guide section 502, and the third guide section 503, respectively. This allows the airflow from the second air duct 300 to be discharged evenly around the perimeter, which can accelerate the mixing with the indoor air.

[0058] Optionally, the first guide section 501, the second guide section 502, and the third guide section 503 are all arc-shaped guide structures that are inclined to one side of the outer periphery of the second air duct 300 and concave inward. This enhances the guiding effect of the first guide section 501, the second guide section 502, and the third guide section 503, allowing the airflow from the second air duct 300 to diffuse evenly and stably into the room, accelerating the mixing with the indoor air and strengthening the air supply effect.

[0059] Optionally, the second air guide 600 includes a flat portion 601 and an arc-shaped portion 602. The flat portion 601 is disposed corresponding to the first air duct 200 and located directly below the first air duct 200; the arc-shaped portion 602 surrounds part or all of the outer periphery of the flat portion 601. In this way, the airflow from the first air duct 200 first flows towards the flat portion 601, and under the guiding effect of the arc-shaped portion 602, the airflow adheres to the vertical wall of the air conditioner unit and flows downward. After the airflow hits the ground, it spreads out to the lower periphery of the air conditioner, forming an effect similar to an "air lake" on the ground, that is, the low wind speed and small temperature difference airflow spreads evenly along the floor, with high air supply temperature efficiency.

[0060] Optionally, the curvature of the arc-shaped portion 602 is equal to that of a quarter circle. If the curvature of the arc-shaped portion 602 is too small or too large, it will fail to guide the airflow, leading to turbulent airflow and reduced airflow efficiency. Setting the curvature of the arc-shaped portion 602 to a quarter circle makes the curvature value more reasonable, allowing it to fully guide the airflow. Under the guidance of the arc-shaped portion 602, the airflow from the first air duct 200 adheres to the vertical wall of the air conditioner unit and flows downwards. After impacting the ground, the airflow spreads outwards around the lower side of the air conditioner, creating an effect similar to an "air lake" on the ground. This low-velocity, low-temperature-difference airflow diffuses evenly along the floor, resulting in high airflow temperature efficiency and enhanced airflow effect.

[0061] Optionally, the arc-shaped portion 602 surrounds the outer periphery of the flat portion 601 except for the side near the air duct portion 104. This prevents the airflow from the first air duct 200 from flowing towards the air duct portion 104, thereby preventing the airflow from being blocked by the outer wall of the air duct portion 104 during the flow process and improving the stability of the airflow process.

[0062] Optionally, an air outlet cavity 101 is defined within the upper shell 103, and the first air duct 200 and the second air duct 300 are located in the remaining area at the lower end of the upper shell 103. This makes the overall structural design more rational, allowing airflow inside the upper shell 103 to flow out through the first air duct 200 and the second air duct 300. Since the first air duct 200 and the second air duct 300 are located on the lower end face of the upper shell 103, the airflow can flow downwards. This allows the airflow from the second air duct 300 to be quickly delivered into the room under the action of the first guide member 500. Under the guidance of the second guide member 600, the airflow from the first air duct 200 adheres to the vertical wall of the air conditioner unit and flows downwards. After impacting the ground, the airflow diffuses outwards towards the lower perimeter of the air conditioner, creating an effect similar to an "air lake" on the ground. This results in high air supply temperature efficiency while reducing costs and saving energy.

[0063] Optionally, the first air guide 500 is arranged outside the air outlet area of ​​the first air duct 200 and is connected to the side wall of the air duct 104 to form a channel for air outlet of the first air duct 200. In this way, on the one hand, the first guide surface of the first guide element 500 forms a guiding effect on the air outlet of the second air duct 300, so that the air outlet air of the second air duct 300 can be evenly distributed around the perimeter, which can accelerate the mixing with indoor air and improve the air outlet efficiency of the air conditioner. On the other hand, the air outlet air of the first air duct 200 can flow through the air outlet channel to the second guide element 600, which can prevent the air outlet air of the first air duct 200 from flowing to other directions except for the second guide element 600 during the flow to the second guide element 600, improve the stability of the airflow, so that the air outlet air of the first air duct 200 can adhere to the vertical wall of the air conditioner unit and flow downward under the guiding effect of the second guide element 600. After the airflow hits the ground, it spreads around the lower side of the air conditioner, forming an effect similar to an "air lake" on the ground. That is, the low wind speed and small temperature difference airflow is evenly diffused along the floor, which has a high air supply temperature efficiency and enhances the air supply effect.

[0064] Optionally, the first air guide 500 is disposed close to the side wall of the air duct 104 and is fixedly connected to the outer side wall of the air duct 104 without gaps. This eliminates gaps at the connection between the first air guide 500 and the side wall of the air duct 104, preventing airflow from flowing through gaps and improving the stability of the airflow process. This allows both the first and second air ducts 200 to supply air according to the user's required airflow, ensuring that the second air duct 300 and the first air duct 200 only supply air within their respective first and second air guide surfaces. This allows the first air guide surface to guide the airflow from the second air duct 300, and the second air guide surface to guide the airflow from the first air duct 200. Consequently, both the second and first air ducts 300 can supply air to the room according to the user's needs, resulting in higher air supply temperature efficiency and enhanced air supply effect.

[0065] Optionally, the first air guide 500 is fixedly connected to the outer wall of the air duct 104 by welding. This eliminates gaps at the connection between the first air guide 500 and the side wall of the air duct 104, preventing airflow from spreading through gaps. Furthermore, the welding method provides greater stability, making it less likely for the first air guide 500 to detach from the side wall of the air duct 104. Consequently, the second air duct 300 and the first air duct 200 only discharge air within their respective first and second air guide surfaces. This allows the first air guide surface to guide the airflow from the second air duct 300, and the second air guide surface to guide the airflow from the first air duct 200. Ultimately, the second air duct 300 and the first air duct 200 can deliver air into the room according to the user's needs, resulting in higher airflow temperature efficiency and enhanced airflow performance.

[0066] Optionally, one side of the first air duct 200 overlaps with the side wall of the air duct section 104, and the second air duct 300 surrounds the remaining sides of the first air duct 200. This ensures that the second air duct 300 surrounding the remaining sides of the first air duct 200 also overlaps with the side wall of the air duct section 104, allowing airflow within the cavity to flow out stably and quickly through the first air duct 200 and the second air duct 300. Furthermore, the second air duct 300 and the first air duct 200 only discharge air within their respective corresponding air outlet areas, enhancing the air delivery effect. Specifically, the airflow from the second air duct 300 flows towards the first guide member 500, and the second air duct 300 only discharges air within the area corresponding to the first guide surface. This allows the first guide surface to guide the airflow from the second air duct 300, thereby enhancing the airflow efficiency of the second air duct. The airflow from the 300 outlet can be evenly distributed around the perimeter, which can accelerate the mixing with the indoor air. The airflow from the first air duct 200 flows to the second guide component 600. The first air duct 200 only discharges air in the area corresponding to the second guide surface, so that the second guide surface can guide the airflow from the first air duct 200. This allows the airflow from the first air duct 200 to adhere to the vertical wall of the air conditioner unit and flow downwards. After the airflow hits the ground, it spreads around the lower side of the air conditioner, forming an effect similar to an "air lake" on the ground. That is, the low wind speed and small temperature difference airflow spreads evenly along the floor, with high air supply temperature efficiency.

[0067] Optionally, the upper surface of the lower shell 102 is positioned opposite to the first air duct 200, and its edge is provided with a downwardly inclined guide surface to guide the airflow from the first air duct 200. In this way, the airflow from the first air duct 200 first flows to the upper surface of the lower shell 102, and under the guidance of the downwardly inclined guide surface, the airflow adheres to the vertical wall of the air conditioner unit and flows downward. After the airflow hits the ground, it spreads out to the lower perimeter of the air conditioner, forming an effect similar to an "air lake" on the ground. That is, the low-speed, small-temperature-difference airflow is evenly diffused along the floor, resulting in high air supply temperature efficiency.

[0068] Optionally, the downward-sloping airflow guiding surface is an outwardly convex arc-shaped surface, with one end connected to the flat portion 601 and the other end connected to the outer wall of the lower shell portion 102. This allows the airflow from the first air duct 200 to adhere to the outer wall of the lower shell portion 102 and flow downwards. In this way, the airflow from the first air duct 200 is only discharged in the area corresponding to the second airflow guiding surface, while the arc-shaped surface allows the second airflow guiding surface to guide the airflow from the first air duct 200. This allows the airflow from the first air duct 200 to adhere to the vertical wall of the air conditioner unit and flow downwards. After the airflow hits the ground, it spreads outwards to the lower perimeter of the air conditioner, forming an effect similar to an "air lake" on the ground. That is, the low-speed, small-temperature-difference airflow is evenly diffused along the floor, resulting in high air supply temperature efficiency.

[0069] like Figure 6-8As shown, in some optional embodiments, the air duct sealing assembly 400 includes: a first sealing plate 401 and a second sealing plate 402. The first sealing plate 401 is adapted to the first air duct 200 and can seal the first air duct 200; the second sealing plate 402 is fixedly connected to the first sealing plate 401 and adapted to the second air duct 300, and can seal the second air duct 300; wherein, the position where the first sealing plate 401 and the second sealing plate 402 are connected is connected to the housing 100 through a rotating shaft 403, and when rotated to a first position, the first air duct 200 is opened and the second air duct 300 is sealed, and when rotated to a second position, the second air duct 300 is opened and the first air duct 200 is sealed. In this way, the second sealing plate 402 is vertically connected to the first sealing plate 401, resulting in a more stable and stronger structure. During rotation of the second sealing plate 402 and the first sealing plate 401, the vertical connection ensures that one of the first air duct 200 and the second air duct 300 is completely closed while the other is fully open. This allows for stable and smooth airflow through either the first air duct 200 or the second air duct 300. Furthermore, the shapes of the first sealing plate 401 and the first air duct 200 are adapted to each other, and the shapes of the second sealing plate 402 and the second air duct 300 are also adapted to each other. This ensures that the first sealing plate 401 and the second sealing plate 402 can rotate from a first position to a second position via the pivot 403, or from a first position to a second position. When the second position is rotated to the first position, the first air duct 200 is fully open, while the second air duct 300 is fully closed. This ensures that there is no gap between the second sealing plate 402 and the second air duct 300 when the second sealing plate 402 closes the second air duct 300. When rotated to the second position, the first air duct 200 is fully closed, while the second air duct 300 is fully open, preventing gaps from forming between the first sealing plate 401 and the first air duct 200. Therefore, the design of the first sealing plate 401 and the second sealing plate 402 ensures that the first air duct 200 and the second air duct 300 only discharge air within their respective corresponding air outlet areas, thus enhancing the air supply effect.

[0070] It is worth noting that the fixed connection between the second sealing plate 402 and the first sealing plate 401 means that the second sealing plate 402 and the first sealing plate 401 are connected at a certain angle, for example, they can be connected perpendicularly.

[0071] Optionally, a transmission wheel is provided on the rotating shaft 403, which is connected to the drive wheel on the motor output shaft. The motor output shaft is mounted on the motor 404, which is located inside the housing 100. In this way, the motor 404 drives the drive wheel to rotate via the output shaft, which in turn drives the transmission wheel to rotate. The rotating transmission wheel then drives the first sealing plate 401 and the second sealing plate 402 connected to the rotating shaft 403 to rotate inside the housing 100. This allows the first sealing plate 401 and the second sealing plate 402 to rotate from a first position to a second position, or from a second position to a first position, via the rotating shaft 403. This makes the driving process more stable and efficient, and improves the stability of the first sealing plate 401 and the second sealing plate 402 during rotation.

[0072] Optionally, the first sealing plate 401 and the second sealing plate 402 are integral structures. An integrally molded structure is non-deformable, has high structural strength, and is more stable, preventing changes in the connection position between the first sealing plate 401 and the second sealing plate 402. This makes the first sealing plate 401 and the second sealing plate 402 more stable during rotation, allowing them to rotate stably and synchronously. This ensures that the first sealing plate 401 is in the open state of the first air duct 200 while the second sealing plate 402 is in the closed state of the second air duct 300, or the first sealing plate 401 is in the closed state of the first air duct 200 while the second sealing plate 402 is in the open state of the second air duct 300. This allows users to selectively choose either the first air duct 200 or the second air duct 300 for airflow, while the other duct remains closed, thus providing the air conditioner with higher controllability.

[0073] Optionally, the first air guide 500 is provided with a raised flange 504 perpendicular to the first air guide 500, and the raised flange 504 is positioned towards the air outlet channel of the first air duct 200. Thus, when it is necessary to open the second air duct 300 and close the first air duct 200, the first sealing plate 401 and the second sealing plate 402 begin to rotate synchronously. The first sealing plate 401 continuously rotates towards the first air duct 200, while the second sealing plate 402 continuously moves away from the second air duct 300 during rotation. When the first sealing plate 401 rotates to the first air duct 200, the flange 504 can block the first sealing plate 401, thereby preventing the first sealing plate 401 from rotating excessively and failing to close the first air duct 200. Therefore, a flange 504 is provided on the first guide member 500 to block the rotation of the first sealing plate 401, preventing the first air duct 200 from failing to be closed due to excessive rotation of the first sealing plate 401. This ensures that when the first sealing plate 401 is in the state of opening the first air duct 200, the second sealing plate 402 is in the state of closing the second air duct 300, or when the first sealing plate 401 is in the state of closing the first air duct 200, the second sealing plate 402 is in the state of opening the second air duct 300.

[0074] Optionally, the length of the flange 504 protruding into the air outlet channel is greater than or equal to 1 cm and less than or equal to 2 cm. If the length of the flange 504 protrusion is too large, it will obstruct the airflow of the first air duct 200, reducing the air outlet efficiency of the first air duct 200. If the length of the flange 504 protrusion is too small, it will not be able to obstruct the first sealing plate 401, causing the first sealing plate 401 to rotate excessively and fail to close the first air duct 200. Therefore, setting the length of the flange 504 protrusion between greater than or equal to 1 cm and less than or equal to 2 cm ensures that the length of the flange 504 protrusion is within a reasonable range. This allows the flange 504 to both obstruct the rotation of the first sealing plate 401, preventing the first air duct 200 from failing to close due to excessive rotation, and without affecting the air outlet of the first air duct 200.

[0075] like Figure 9-11 As shown, the air conditioner cabinet unit provided in this embodiment further includes a deflector plate 700. The deflector plate 700 is disposed on one side of the bottom of the lower housing 102 and is configured to receive the airflow from the first air duct 200. Thus, when the airflow from the first air duct 200 flows downwards along the vertical wall of the air conditioner cabinet unit to the deflector plate 700, the deflector plate 700 can receive the airflow, thereby increasing the thickness of the airflow, preventing the warm airflow from sinking too much, enhancing the air delivery effect, and further improving the air delivery temperature efficiency of the air conditioner cabinet unit.

[0076] Optionally, the bottom of the lower shell 102 is provided with an installation port 800, and the guide plate 700 is disposed in the installation port 800. In this way, the overall structural design is more reasonable and it is easier to install the guide plate 700.

[0077] Optionally, the air deflector 700 includes a fixed part 701 and a telescopic part 702. One end of the fixed part 701 extends into the mounting port 800, and the other end overlaps with the mounting port 800; the telescopic part 702 is connected to the fixed part 701. In this way, when the airflow from the first air duct 200 flows downward against the vertical wall of the air conditioner unit to the air deflector 700, the telescopic part 702 extends out of the lower shell 102, thereby catching the airflow from the first air duct 200, increasing the thickness of the air duct, preventing the warm airflow from sinking too much, strengthening the air delivery effect, and further improving the air delivery temperature efficiency of the air conditioner unit.

[0078] Optionally, the fixing part 701 includes a concave groove 703. The telescopic part 702 is disposed within the concave groove 703. Thus, when the first air duct 200 is in the open state, the telescopic part 702 extends from the concave groove 703 to catch the airflow from the first air duct 200, increasing the thickness of the airflow and preventing the warm airflow from sinking too much, thereby enhancing the air delivery effect. When the first air duct 200 is in the closed state, the telescopic part 702 retracts into the concave groove 703, which not only prevents the telescopic part 702 from occupying indoor space but also provides protection for the telescopic part 702.

[0079] Optionally, a tension ring 704 is provided at one end of the telescopic part 702 that extends out of the lower housing 102. This makes it easier for the user to manually pull the telescopic part 702 out of the concave groove 703, improving the convenience of use.

[0080] Optionally, the telescopic section 702 consists of one or more telescopic plates. In this way, the user can freely adjust the length of the telescopic section 702 according to the usage needs, and the airflow from the first air duct 200 forms an "air lake" of optimal thickness on the ground, improving the air outlet effect and enhancing the air supply temperature efficiency of the air conditioning unit.
