Description

Technical Field

[0001] This utility model relates to the field of filtration structure technology, and in particular to an air outlet assembly, a duct air conditioner, and an air conditioning unit. Background Technology

[0002] Ductless air conditioners, also known as concealed air duct air conditioners, are widely used due to their low cost, ease of maintenance, and suitability for Chinese users' habits. These indoor units, installed on the upper wall or ceiling, typically have side-discharge airflow. During heating, the low density of hot air causes it to rise, failing to reach users in the lower part of the room. This results in uneven temperature distribution, with warmer areas at the top and colder areas at the bottom, particularly affecting users prone to cold hands and feet.

[0003] Existing technology provides a method to switch the airflow direction of an air conditioner indoor unit to adjust the air outlet direction, specifically including a housing and a rotating air duct assembly. The housing has heating air vents and cooling air vents; the rotating air duct assembly is rotatable relative to the housing so that the air conditioner indoor unit can achieve different air inlet and outlet vents for cooling and heating modes. When cooling, air enters from the heating air vent and exits from the cooling air vent; when heating, air enters from the cooling air vent and exits from the heating air vent, thereby greatly alleviating the problem of temperature distribution in the room being hot at the top and cold at the bottom.

[0004] However, ducted air conditioners need to filter the air when they draw in air. For indoor air conditioners that require switching the air outlet status, the filter cannot adapt when the air outlet switches from air intake to air outlet. The filter blocks part of the airflow, resulting in a small air volume. Moreover, the dust and impurities filtered on the filter will be blown back into the room, causing indoor air pollution again and seriously affecting the user experience. Utility Model Content

[0005] To address the technical problem of the inability to adjust the filter of existing ducted air conditioners, which affects user experience, an air outlet component, ducted air conditioner, and air conditioning unit are provided that can be additionally installed at the air outlet of the ducted air conditioner and can switch between filtering and avoidance modes to improve user experience.

[0006] An air vent assembly includes:

[0007] A housing having at least two air passages formed thereon;

[0008] The filter structure corresponds one-to-one with the air passage, and the air outlet assembly has a filtering state in which the filter structure blocks the air passage and an avoidance state in which the filter structure avoids the air passage.

[0009] Every two of the air passages constitute an air passage group. When the air outlet assembly is in the avoidance state, in the same air passage group, the two filter structures corresponding to the two air passages are stacked on top of each other along the thickness direction of the housing.

[0010] In the same air passage group, the stacking positions of the two air passages and the filter structure are arranged in an L-shape, and the stacking position is located at the apex of the L-shape.

[0011] The two L-shapes are joined together to form a rectangular shape.

[0012] The filter structure includes a first filter structure and a second filter structure. The distance from the first filter structure to the first side of the housing is less than the distance from the second filter structure to the second side of the housing. In the same air passage group, the two air passages include a first air passage and a second air passage. The first filter structure is provided at the first air passage, and the second filter structure is provided at the second air passage.

[0013] The air vent assembly also includes a drive mechanism, which is disposed within the housing, and all the filter structures are connected to the drive mechanism in a transmission manner.

[0014] The air vent assembly also includes a drive shaft, a driven shaft, and a rack. The drive shaft is connected to the drive mechanism, the driven shaft meshes with the drive shaft, and the rack corresponds one-to-one with the filter structure, and the rack meshes with either the drive shaft or the driven shaft.

[0015] A ducted air conditioner includes the aforementioned air outlet assembly.

[0016] The ducted air handling unit has at least two air outlets, and each air outlet is provided with an air outlet assembly.

[0017] The air vents include a downwind vent and a side vent. The ducted air conditioner has a first state where the downwind vent is the air inlet and the side vent is the air outlet, and a second state where the side vent is the air inlet and the downwind vent is the air outlet. The air vent assembly is provided at both the downwind vent and the side vent. When the ducted air conditioner is in the first state, the air vent assembly at the downwind vent is in the filtering state, and the air vent assembly at the side vent is in the avoidance state. When the ducted air conditioner is in the second state, the air vent assembly at the side vent is in the filtering state, and the air vent assembly at the downwind vent is in the avoidance state.

[0018] An air conditioning unit includes the aforementioned air outlet assembly or the aforementioned duct unit.

[0019] The air vent assembly, ducted air conditioner, and air conditioning unit provided by this utility model form an air passage within the housing and are equipped with a movable filter structure to shield and filter or allow ventilation through the air passage. This effectively avoids the problems of reduced airflow and dust backflow into the room caused by the filter always being placed at the air vent in the prior art, thus effectively improving the user experience. At the same time, multiple air passages are set up and the filter structures are stacked on top of each other, so that the effective ventilation area of ​​the air vent assembly is increased as much as possible without the filter structure being moved out of the housing, thereby further increasing the airflow of the ducted air conditioner and air conditioning unit using the air vent assembly, and further improving the user experience.

[0037] Existing technology provides a method to switch the airflow direction of an indoor air conditioning unit to adjust its air outlet direction, specifically including a housing and a rotating duct assembly. The housing has heating and cooling air outlets; the rotating duct assembly is rotatable relative to the housing so that the indoor air conditioning unit can achieve different air inlet and outlet modes for cooling and heating. In cooling mode, air enters from the heating air outlet and exits from the cooling air outlet; in heating mode, air enters from the cooling air outlet and exits from the heating air outlet, thus greatly alleviating the problem of hotter upper and colder lower temperatures in the room. However, ducted air conditioners require air filtration when drawing in air. For the aforementioned indoor air conditioning unit that requires switching air outlet states, when the air outlet switches from inlet to outlet, the filter cannot adapt accordingly. The filter blocks part of the outlet airflow, resulting in low air volume, and the dust and impurities filtered on the filter are blown back into the room, causing further indoor air pollution and seriously affecting the user experience.

[0038] Therefore, this application provides a method such as Figures 1 to 10 The air vent assembly shown includes: a housing 1, on which at least two air passages 2 are formed; a filter structure 3, which corresponds one-to-one with the air passages 2, and the air vent assembly has a filtering state in which the filter structure 3 shields the air passages 2 and an avoidance state in which the filter structure 3 avoids the air passages 2; every two air passages 2 constitute an air passage group, and when the air vent assembly is in the avoidance state, in the same air passage group, the two filter structures 3 corresponding to the two air passages 2 are stacked on top of each other along the thickness direction of the housing 1. An air passage 2 is formed within the housing 1, and a movable filter structure 3 is installed to shield and filter the air passage 2 or to allow ventilation. This effectively avoids the problems of reduced airflow and dust backflow into the room caused by the filter always being placed at the air outlet in the prior art, thus effectively improving the user experience. At the same time, multiple air passages 2 are set up and the filter structures 3 are stacked on top of each other, making full use of the thickness of the housing 1. This maximizes the effective ventilation area of ​​the air outlet assembly without moving the filter structure 3 out of the housing 1, thereby further improving the airflow of ducted air conditioners and air conditioning units that use the air outlet assembly, and further improving the user experience.

[0039] like Figure 1As shown, in the same airflow channel group, the stacking positions of the two airflow channels 2 and the filter structure 3 are arranged in an L-shape, with the stacking position located at the apex of the L-shape. This L-shaped distribution minimizes the movement distance of the filter structure 3, improves the state switching speed of the air outlet assembly, and allows for a reasonable stacking position to minimize the occupancy of the housing 1, thereby increasing the flow area of ​​the airflow channel 2 and improving the airflow of the air outlet assembly.

[0040] Preferably, the two L-shaped structures are joined together to form a rectangle, which rationally distributes the position of the air passage 2 and maximizes the utilization of the size of the housing 1, thereby increasing the flow area of ​​the air passage 2 and improving the air volume of the air outlet assembly. The rectangle formed by the joining is a portion of the rectangle of the housing 1; thus, multiple rectangles can effectively divide the rectangle of the housing 1, further increasing the flow area of ​​the air passage 2 and improving the air volume of the air outlet assembly.

[0041] The filter structure 3 includes a first filter structure 31 and a second filter structure 32. The distance from the first filter structure 31 to the first side of the housing 1 is less than the distance from the second filter structure 32 to the second side of the housing 1. In the same airflow channel group, the two airflow channels 2 include a first airflow channel 21 and a second airflow channel 22. The first filter structure 31 is disposed at the first airflow channel 21, and the second filter structure 32 is disposed at the second airflow channel 22. By utilizing the difference in distance, the first filter structure 31 and the second filter structure 32 will not interfere with each other when stacked, ensuring reliable switching of the air outlet assembly.

[0042] The housing 1 has a second side opposite to the first side. The first filter structure 31 is close to the second side, while the second filter structure 32 is close to the first side. The air outlet assembly also includes a connecting pipe section 4, which is disposed inside the housing 1. At the first air passage 21, the connecting pipe section 4 is positioned between the first filter structure 31 and the first side. The connecting pipe section 4 guides the gas flowing through the first air passage 21, preventing it from flowing into the housing 1 due to its thickness, thus improving the reliability of the air outlet assembly. Similarly, at the second air passage 22, the connecting pipe section 4 is positioned between the second filter structure 32 and the second side. The connecting pipe section 4 also guides the gas flowing through the second air passage 22, preventing it from flowing into the housing 1 due to its thickness, thus improving the reliability of the air outlet assembly.

[0043] In order to achieve automatic switching of the state of the air outlet assembly, the air outlet assembly also includes a drive mechanism 5. The drive mechanism 5 is disposed inside the housing 1, and all the filter structures 3 are connected to the drive mechanism 5 for transmission. The drive mechanism 5 drives the filter structures 3 to move, thereby enabling the filter structures 3 to freely switch in their corresponding air passage 2 and stacking positions, realizing the automatic switching of the air outlet assembly. The drive mechanism 5 only needs to act according to the set instructions or target instructions.

[0044] Specifically, because the L-shape formed by the two air passage groups is interlocked, the movement directions of the filter structure 3 in the air passage group are different. Therefore, the air outlet assembly also includes a drive shaft 6, a driven shaft 7, and a rack 8. The drive shaft 6 is connected to the drive mechanism 5, the driven shaft 7 meshes with the drive shaft 6, and the rack 8 corresponds one-to-one with the filter structure 3, meshing with either the drive shaft 6 or the driven shaft 7. By setting the rack 8 on the filter structure 3, the rack 8 can mesh with the gears on the drive shaft 6 or the driven shaft 7. Thus, when the drive shaft 6 is driven by the drive mechanism 5, the driven shaft 7 is driven by the drive shaft 6. The rotation directions of the drive shaft 6 and the driven shaft 7 are opposite, thereby driving the meshing rack 8 to move in different directions, thus enabling the filter structure 3 to move in different directions.

[0045] A ducted air conditioner includes the aforementioned air outlet assembly.

[0046] The ducted air handling unit has at least two air outlets, and each air outlet is provided with an air outlet assembly.

[0047] The air vents include a downdraft 11 and a side vent 12. The ducted air conditioner has a first state where the downdraft 11 serves as an air inlet and the side vent 12 serves as an air outlet, and a second state where the side vent 12 serves as an air inlet and the downdraft 11 serves as an air outlet. Air vent assemblies are provided at both the downdraft 11 and the side vent 12. When the ducted air conditioner is in the first state, the air vent assembly at the downdraft 11 is in a filtering state, and the air vent assembly at the side vent 12 is in a clearance state. At this time, the filter structure 3 at the downdraft 11, which serves as the air inlet, blocks the corresponding air passage 2, allowing the gas to be... After filtration, the gas enters the ducted air conditioner. When the gas is discharged through the ducted air conditioner, the filter structure 3 at the side air outlet 12 avoids the corresponding air passage 2, ensuring the exhaust efficiency of the ducted air conditioner. When the ducted air conditioner is in the second state, the air outlet assembly at the side air outlet 12 is in the filtration state, and the air outlet assembly at the down air outlet 11 is in the avoidance state. At this time, the filter structure 3 at the side air outlet 12, which serves as the air inlet, blocks the corresponding air passage 2, allowing the gas to be filtered before entering the ducted air conditioner. When the gas is discharged through the ducted air conditioner, the filter structure 3 at the down air outlet 11 avoids the corresponding air passage 2, ensuring the exhaust efficiency of the ducted air conditioner.

[0048] An air conditioning unit includes the aforementioned air outlet assembly or the aforementioned duct unit.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
