Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and particularly relates to an adjustable air supply outlet and an air conditioner. Background Art

[0002] The production workshop of a cigarette factory belongs to a large and tall space. At present, the air supply and return mode in the workshop is "top supply and top return", and an air handling unit, that is, an air handling unit, is used to adjust the temperature and humidity of multiple workshops in a "one-drag-many" manner. At present, in the variable air volume control of the air conditioner in the cigarette factory, manual air valves are mainly used for air volume distribution, and the air supply outlet is a swirl air outlet. This results in that the air volume distribution cannot be adjusted in time according to the workshop requirements. At the same time, when the air volume is small, the swirl air outlet causes insufficient wind penetration, and the treated air cannot be smoothly sent to the lower part of the workshop in the top supply mode, greatly reducing the ability of the combined air conditioner to control the temperature and humidity in the workshop and causing energy waste.

[0003] Due to different external environments and internal heat sources in different workshops, it is easy to cause different deviations between the temperature and humidity at the same moment in different workshops and the process requirements. Under the control conditions of the same air conditioner, variable air volume can be used to supply air according to demand; but at the same time, due to the large and tall space attribute of the cigarette workshop, when the air supply volume changes, especially when the air volume decreases, it is necessary to ensure that the air supply has sufficient wind speed to reach the lower space. Therefore, it is necessary to change the air supply outlet to ensure reasonable wind speed.

[0004] Chinese Patent CN202311376264.2 provides a variable cross-section air guiding structure, which includes at least two air guiding components arranged at intervals at the air outlet 100 of the air supply device. An air flow channel for the air supply of the air supply device is formed between adjacent two air guiding components, and the minimum distance between adjacent two air guiding components can be adjusted in size. It can solve the problems of single air supply speed and single air supply distance of the existing air supply device to a certain extent. However, it still has the following deficiencies: First, the cross-section of the air flow channel is long strip-shaped, with poor symmetry, scattered air outlet, weak penetration, and insufficient effect when used in air conditioners for large and tall spaces. Second, the transmission part for controlling the air guiding component is located in the air flow channel, which is easy to cause air flow disturbance or diversion. Even if the rectification is carried out by using another air guiding plate provided by it, it is easy to cause unnecessary air resistance and design difficulty. For example, the air guiding plate at the edge actually does not rectify and guide the air flow in the air flow channel but only avoids the air flow passing through the transmission part.

[0005] How to provide a structure that can change the cross-sectional area and direction of the air supply channel, so that the air supply of the air conditioner acts on the area with temperature and humidity gradient in different ways, and realizes the rapid and uniform adjustment of the temperature and humidity inside the workshop is an urgent technical problem in this field. Summary of the Utility Model

[0006] In view of the existing phenomena, the present utility model provides an adjustable air outlet and an air conditioner, which at least solve one of the above technical problems.

[0007] The technical solution provided by this application is an adjustable air outlet, which includes: a wind barrel with an air outlet, and a deflector arranged evenly along the circumferential direction of the wind barrel, which can approach or move away from the center of the air outlet; the deflector can enclose a diversion channel to form a diversion for the air flow flowing out through the air outlet.

[0008] Further, when the end of the diversion channel is smaller than the air outlet, the cross-sectional area of the diversion channel gradually shrinks along the air flow direction.

[0009] Further, it includes a rotating shaft parallel to the air outlet, and the deflector is rotatably arranged around the rotating shaft.

[0010] Further, the deflector includes a first deflector blade and a second deflector blade, which are alternately distributed circumferentially. The first deflector blade includes a receiving portion for receiving adjacent parts of the second deflector blade when the air outlet channel shrinks.

[0011] Further, the rotating shaft includes a first rotating shaft and a second rotating shaft. The first rotating shaft is rotatably connected to the wind barrel and the first deflector blade, and the second rotating shaft is rotatably connected to the first deflector blade and the second deflector blade.

[0012] Further, it includes a driving shaft and a transmission belt tensioned between the driving shaft and the rotating shaft.

[0017] The beneficial effects of this application are as follows:

[0018] This application provides an adjustable air outlet, that is, an air outlet with a variable air outlet channel shape. When the deflector does not block the air flow flowing out of the air outlet, the air outlet channel is the inner wall of the wind barrel; when the deflector moves to block part of the air outlet, the air outlet channel is jointly composed of the inner wall of the wind barrel and the diversion channel formed by the deflector, and the diversion channel has a smaller end. The movable setting of the deflector can make the blocking degree adjustable, that is, the diversion channel is adjustable, so that this application can adjust the wind speed under the condition of constant air volume.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0028] In the description of the present application, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the present application, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0030] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] Such as Figures 1-3 , Embodiment 1 provides an adjustable air outlet, including: a wind duct 1 having an air outlet 100 and a deflector 2 uniformly arranged along the circumferential direction of the wind duct 1 and capable of approaching or departing from the center of the air outlet 100; the deflector 2 encloses a diversion channel 200 to form a diversion for the air flow flowing out through the air outlet 100.

[0032] The present application provides an adjustable air outlet, that is, an air outlet with a variable air outlet channel shape. When the deflector 2 does not block the air flow flowing out of the air outlet 100, the air outlet channel is the inner wall of the wind duct; when the deflector 2 moves to block part of the air outlet 100, the air outlet channel is jointly composed of the inner wall of the wind duct 1 and the diversion channel 200 formed by the deflector 2, and the diversion channel 200 has a smaller end. The movable setting of the deflector 2 enables the blocking degree to be adjustable, that is, the diversion channel 200 is adjustable, so that the present application can adjust the air velocity under the condition of constant air volume. Such as Figure 3Top view schematic diagram of the adjustment of the end of the diversion channel. In the left figure before the end contraction, the end of the diversion channel is larger than the air outlet 100, and the air flow directly exits through the air outlet 100; in the right figure after the end contraction, the diversion channel is jointly composed of the air outlet 100 and the end of the diversion member 2, and the air flow is diverted by the diversion member 2 after exiting through the air outlet 100.

[0033] The circumferentially uniformly arranged diversion member 2 makes the shape center of the air outlet channel symmetric, the air outlet is concentrated, and the penetration power is strong, which is suitable for adjusting the wind speed in a tall space so that the air outlet reaches the bottom. The diversion member 2 of the present application can be used for air ducts of various shapes, especially for cylindrical air ducts.

[0034] To avoid sudden changes in the shape of the air flow channel and reduce the air outlet resistance, when the end of the diversion channel 200 is smaller than the air outlet 100, the cross-sectional area of the diversion channel 200 gradually decreases along the air flow direction.

[0035] In this embodiment, it further includes a rotating shaft disposed on the air duct 1 and parallel to the air outlet 100, and the diversion member 2 is rotatably disposed around the rotating shaft. By rotating the rotating shaft of the diversion member 2, the end far from the rotating shaft can be close to or away from the central axis of the air duct, so that the shape of the air outlet channel formed by the edge formed by the end of the diversion member changes to form diversion, adjusting the size of the end of the air outlet channel, and the formed diversion channel 200 has a cross-sectional area that gradually decreases along the air flow direction.

[0036] Considering that a continuous and flat air outlet channel can make the air outlet more concentrated, and it is difficult for a diversion member with a single shape and movement trajectory to achieve a radially uniformly tapered air outlet cross-section. In some embodiments, the diversion member 2 includes a first diversion member and a second diversion member that are alternately distributed. Combining two or even more different diversion members in terms of shape and movement trajectory is more convenient to make the shape of the end of the air outlet channel more continuous and flat. The second diversion member is used to reduce the air flow from adjacent first diversion members between the first diversion members and the air duct.

[0037] Such as Figure 1 , specifically, in this embodiment, the diversion member 2 includes a first diversion leaf 21 and a second diversion leaf 22, and the first diversion leaf 21 and the second diversion leaf 22 are circumferentially alternately distributed. Among them, the first diversion leaf 21 is an implementation manner of the first diversion member, and the second diversion leaf 22 is an implementation manner of the second diversion member. In other embodiments, the second diversion member can also be set in other forms. For example, it can be set as a hinge connecting adjacent first diversion members, and the movement of the first diversion member is cooperated by unfolding or folding to achieve diversion.

[0038] Such as Figure 1 , in this embodiment, to avoid collision interference between the first diversion leaf 21 and the second diversion leaf 22 when the air outlet channel contracts, the first diversion leaf 21 further includes a receiving portion 211 for receiving adjacent partial second diversion leaves 22 when the air outlet channel contracts.

[0039] like Figures 1-2 Since the wind tube 1 of this embodiment is a cylinder, in order to ensure the rectifying effect, the first guide vane 21 and the second guide vane 22 are both curved discs adapted to the shape of the cylinder. If the rotating shafts of the first guide vane 21 and the second guide vane 22 are both set on the wind tube 1, interference will occur. In this embodiment, the rotating shaft includes a first rotating shaft 31 and a second rotating shaft 32. The first rotating shaft 31 is rotatably connected to the wind tube 1 and the first guide vane 21, and the second rotating shaft 32 is rotatably connected to the first guide vane 21 and the second guide vane 22.

[0040] Preferably, the shape of the accommodating portion 211 is adapted to the preset motion trajectory of the second guide vane 22, so that the motion of the first guide vane 21 can be used to drive the motion of the second guide vane 22 and limit the position of the second guide vane 22, without applying additional power or limiting the position of the second guide vane 22 or the second rotating shaft 32. The preset motion trajectory can be comprehensively designed according to the motion trajectory of the first guide vane 21 and the ideal shape of the air outlet channel.

[0041] In this embodiment, the first rotating shaft 31 is arranged on the outside of the air duct 1 and the second rotating shaft 32 is arranged on the inside of the accommodating portion 211, so that the rotating shaft and the outer wall of the guide member 2 are outside the air flow channel to avoid diversion and turbulence of the air flow and do not affect the guidance of the guide member 2.

[0042] In this embodiment, a driving shaft 4 and a transmission belt 5 tensioned between the driving shaft 4 and the rotating shaft are included. Belt drive has the advantages of simple structure and stable transmission, and is convenient to be set to have a larger center distance. In particular, since the flow guide 2 needs to load air flow resistance when guiding the flow, it will cause a certain load on the rotating shaft, and the belt drive is particularly suitable for the sports scene that requires buffering, vibration absorption and overload protection.

[0043] In order to facilitate the adjustment of the transmission belt 5, in this embodiment, a rocker 6 is provided on the driving shaft 4 and is convenient for rotating the driving shaft 4. The rocker 6 can be connected to a power source and is also convenient for manual adjustment.

[0044] In this embodiment, a motor is included which is transmission-connected to the flow guide, specifically connected to the driving shaft and drives the first rotating shaft 31 through the transmission belt 5. The motor is easy to control and has a fast response, and is suitable as a power source for this application.

[0045] Taking into account that temperature and humidity are the main parameters of the working conditions of the air outlet, in order to enable the air outlet to further have the function of adjusting the air outlet channel according to the working conditions, in this embodiment, it includes a controller electrically connected to the motor, and the controller includes a temperature and humidity sensor unit.

[0046] Embodiment 2 is an air conditioner, which includes the adjustable air outlet of embodiment 1, has all its technical features, and therefore also includes all its beneficial effects.

[0047] The content described above can be implemented alone or in various combinations, and these variant ways are all within the protection scope of the present utility model.

[0048] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
