Description

Technical Field

[0001] The invention relates to the technical field of filtering structures, in particular to an air outlet component, an air duct unit and an air conditioning unit. Background Art

[0002] Duct air conditioner is the abbreviation of hidden air duct air conditioner, which can also be called air conditioner duct air conditioner or duct air conditioner. Duct air conditioner is cheap, easy to maintain, suitable for Chinese people's air conditioning usage habits, and widely used. Duct indoor units installed on the wall above the room or on the ceiling of the room are mostly side-outlet. When heating, the hot air density is low, and the side-outlet air causes the hot air flow to float up and cannot blow to users in the lower area of ​​the room. The temperature distribution in the room is uneven, causing the problem of hot top and cold bottom. Especially for users who are prone to cold hands and feet, the experience is poor.

[0003] The prior art provides a method for switching the airflow direction of an indoor unit of an air conditioner to adjust the air outlet direction of the indoor unit, which specifically includes a housing and a rotating air duct assembly. The housing has a heating air outlet and a cooling air outlet; the rotating air duct assembly can rotate relative to the housing so that the indoor unit of the air conditioner can achieve different air inlets and outlets in cooling and heating modes. When cooling, the air enters from the heating air outlet and exits from the cooling air outlet; when heating, the air enters from the cooling air outlet and exits from the heating air outlet, thereby greatly alleviating the problem of temperature distribution in the room being hot at the top and cold at the bottom.

[0004] However, the duct air conditioner needs to filter the gas when it inhales the gas. For the air conditioner indoor unit that needs to switch the air outlet status, when the air outlet switches from air inlet to air outlet, the filter cannot be adaptively switched. The filter blocks part of the air flow, resulting in a small air volume. In addition, the dust and impurities filtered by the filter will be blown back into the room, causing indoor air pollution again, which seriously affects the user experience. Summary of the invention

[0005] In order to solve the technical problem in the prior art that the filter of the duct air conditioner cannot be adjusted and affects the user experience, an air outlet component, a duct air conditioner and an air conditioning unit are provided, which can be additionally arranged at the air outlet of the duct air conditioner and can be switched between a filtering state and an avoidance state to improve the user experience.

[0036] The prior art provides a method for switching the airflow direction of an air conditioner indoor unit to adjust the air outlet direction of the indoor unit, which specifically includes a shell and a rotating air duct assembly. The shell has a heating air outlet and a cooling air outlet; the rotating air duct assembly can rotate relative to the shell so that the air conditioner indoor unit can realize different inlet and outlet air outlets in cooling and heating modes. When cooling, the air enters from the heating air outlet and exits from the cooling air outlet; when heating, the air enters from the cooling air outlet and exits from the heating air outlet, thereby greatly alleviating the problem of the temperature distribution in the room being hot on the top and cold on the bottom. However, the duct machine needs to filter the gas when inhaling the gas, and for the air conditioner indoor unit that needs to switch the air outlet state, when the air outlet is switched from air inlet to air outlet, the filter cannot be adaptively switched, and the filter blocks part of the outlet airflow, resulting in a small air volume, and the dust and impurities filtered on the filter will be blown back into the room, causing indoor air pollution again, seriously affecting the user experience.

[0037] To this end, the present application provides a Figures 1 to 10 The air outlet assembly shown includes: a shell 1, on which at least two air passages 2 are formed; a filter structure 3, which corresponds one-to-one to the air passages 2, and the air outlet assembly has a filtering state in which the filter structure 3 shields the air passages 2 and a avoiding state in which the filter structure 3 avoids the air passages 2; every two of the air passages 2 constitute an air passage group, and when the air outlet assembly is in the avoiding state, in the same air passage group, the two filter structures 3 corresponding to the two air passages 2 are stacked on each other along the thickness direction of the shell 1. An air passage 2 is formed in the shell 1, and a movable filter structure 3 is provided to shield and filter the air passage 2 or avoid ventilation, thereby effectively avoiding the problem in the prior art that the filter is always provided at the air outlet, resulting in reduced air volume and dust being blown back into the room, and effectively improving the user experience. At the same time, multiple air passages 2 are provided, and the filter structures 3 are stacked on each other to fully utilize the thickness of the shell 1, so that the effective ventilation area of ​​the air outlet assembly is increased as much as possible without moving the filter structure 3 out of the shell 1, thereby further increasing the air volume of the duct machine and air-conditioning unit using the air outlet assembly, and further improving the user experience.

[0038] like Figure 1As shown, in the same wind channel group, the stacking positions of the two wind channels 2 and the filter structure 3 are distributed in an L shape, and the stacking position is located at the vertex of the L. By utilizing the L-shaped distribution, the moving distance of the filter structure 3 is reduced as much as possible, the state switching speed of the air outlet assembly is improved, and the stacking position can be reasonably set to reduce the occupation of the stacking position on the housing 1 as much as possible, thereby increasing the flow area of ​​the wind channel 2 and the air volume of the air outlet assembly.

[0039] Preferably, the two L-shaped shapes are combined to form a rectangular shape, the position of the air passage 2 is reasonably distributed, and the size of the housing 1 is used to the maximum extent, thereby increasing the flow area of ​​the air passage 2 and the air volume of the tuyere assembly. The combined rectangular shape is a part of the rectangle of the housing 1, and the plurality of rectangular shapes can just divide the rectangle of the housing 1, thereby further increasing the flow area of ​​the air passage 2 and the air volume of the tuyere assembly.

[0040] The filter structure 3 includes a first filter structure 31 and a second filter structure 32, the distance between the first filter structure 31 and the first side of the housing 1 is smaller than the distance between the second filter structure 32 and the second side of the housing 1, and in the same wind passage group, the two wind passages 2 include a first wind passage 21 and a second wind passage 22, the first wind passage 21 is provided with the first filter structure 31, and the second wind passage 22 is provided with the second filter structure 32. By utilizing the difference in distance, the first filter structure 31 and the second filter structure 32 will not interfere with each other when they are stacked, thereby ensuring reliable state switching of the air outlet assembly.

[0041] In which, the shell 1 has a second side opposite to the first side, and 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 arranged in the shell 1. At the first air passage 21, the connecting pipe section 4 is arranged between the first filter structure 31 and the first side. The connecting pipe section 4 is used to guide the gas flowing through the first air passage 21 to avoid flowing into the shell 1 due to the thickness of the shell 1, thereby improving the working reliability of the air outlet assembly. Similarly, at the second air passage 22, the connecting pipe section 4 is arranged between the second filter structure 32 and the second side. The connecting pipe section 4 can also be used to guide the gas flowing through the second air passage 22 to avoid flowing into the shell 1 due to the thickness of the shell 1, thereby improving the working reliability of the air outlet assembly.

[0042] In order to realize automatic switching of the state of the air outlet assembly, the air outlet assembly also includes a driving mechanism 5, which is arranged in the shell 1, and all the filter structures 3 are connected to the driving mechanism 5 in transmission. The driving mechanism 5 is used to drive the filter structure 3 to move, so that the filter structure 3 can be freely switched between its corresponding air passage 2 and stacking position, thereby realizing automatic switching of the air outlet assembly. The driving mechanism 5 only needs to act according to the set instructions or target instructions.

[0043] Specifically, since the L-shapes formed by the two air passage groups are spliced ​​together, the moving directions of the filter structures 3 in the air passage groups are different. For this reason, the air outlet assembly further includes a driving shaft 6, a driven shaft 7 and a rack 8. The driving shaft 6 is connected to the driving mechanism 5, the driven shaft 7 is meshed with the driving shaft 6, the rack 8 corresponds to the filter structure 3 one by one, and the rack 8 is meshed with the driving shaft 6 or the driven shaft 7. By arranging the rack 8 on the filter structure 3, the rack 8 can be meshed with the gear arranged on the driving shaft 6 or the driven shaft 7, so that when the driving shaft 6 is driven by the driving mechanism 5, the driven shaft 7 is driven by the driving shaft 6, and the rotation directions of the driving shaft 6 and the driven shaft 7 are opposite, so that the meshed rack 8 can be driven to move in different directions, thereby realizing the movement of the filter structure 3 in different directions.
