[0005] a fixed air duct;

[0006] an air outlet assembly in communication with the fixed air duct, capable of being driven by a driving mechanism to make lifting motion relative to the fixed air duct, the air outlet assembly being provided with an upper air outlet for upward air outlet;

[0007] wherein the air outlet assembly and the front side of the fixed air duct jointly define a front air outlet for front air outlet at a raised position.

DETAILED DESCRIPTION

[0049] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to all alternative embodiments, as would be understood by one skilled in the art. Overly detailed description of the system and method according to the exemplary embodiments may not be required in this document. It is to be understood that the following description is exemplary only and is intended to provide a description for the appropriate methods and apparatuses according to the exemplary embodiments. As such, the following description is not intended to be limiting or all inclusive, and will be supplemented as necessary by the ordinarily skilled artisan.

[0050] It should be noted that all the actions of obtaining signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization given by the corresponding device owner.

[0051] The exemplary embodiments of the present disclosure provide an air outlet device, which is optionally applicable to an air conditioner, including but not limited to a cabinet air conditioner, a wall-mounted air conditioner, a fresh air machine, and an air purification device, etc. The fresh air machine includes an outdoor circulation type, an indoor circulation type, or an indoor and outdoor double circulation type.

[0052] As shown in Figures 1 to 7 The air outlet device provided by the present disclosure includes a fixed air duct 1 and an air outlet assembly 2. The air outlet assembly 2 communicates with the fixed air duct 1. The air outlet assembly 2 can be driven by a driving mechanism 3 to move up and down relative to the fixed air duct 1. The air outlet assembly 2 is provided with an upper air outlet 12 for upward air outlet. Wherein, the air outlet assembly 2 and the front side of the fixed air duct 1 jointly define a front air outlet 11 for forward air outlet at the raised position. It should be noted that front, back, left, right, up and down here are defined in the normal use state of the air conditioner, i.e. in the use and installation state, the side facing the user is the front side. Inside and outside are relative to the inside and outside space of the air conditioner.

[0053] When the air outlet assembly 2 is lowered, the upward air outlet of the air outlet device can be realized through the upper air outlet 12 to meet the conventional upward air supply demand; when the air outlet assembly 2 is raised, the air outlet assembly 2 cooperates with the front side of the fixed air duct 1 to form the front air outlet 11, at this time the upper air outlet 12 can work with the front air outlet 11 at the same time to realize the composite air outlet of upward and forward, effectively expand the air outlet coverage range, meet the diversified use scenarios of users, and the forward air outlet faces the upper body area of the human body, which can more quickly meet the temperature regulation demand of the upper body area of the human body than the upward air outlet, and improve the body comfort during refrigeration / heating.

[0054] At the same time, the air outlet device provided by the present disclosure dynamically cooperates with the fixed air duct 1 through the lifting of the air outlet assembly 2, i.e. forms the front air outlet 11, without the need to set a complex opening and closing mechanism, or to realize the upward air outlet and the forward air outlet through the complex design of the air outlet assembly 2, thereby reducing the design difficulty of the air outlet device, and without the need to additionally add a complex mechanism, which is conducive to simplifying the structural design of the air conditioner.

[0055] In some possible embodiments, as shown in Figure 1 or Figure 5As shown, the air outlet assembly 2 can include a partition structure 21, which separates the inner cavity of the fixed air duct 1 into an upward air outlet channel 13 and a forward air outlet channel 14, the upward air outlet channel 13 being in communication with the upper air outlet 12, and the forward air outlet channel 14 being in communication with the front air outlet 11. By separating the inner cavity of the fixed air duct 1 into the independent upward air outlet channel 13 and the forward air outlet channel 14 through the partition structure 21, the airflow path separation can be achieved, the upward air outlet channel 13 corresponding to the upper air outlet 12, and the forward air outlet channel 14 corresponding to the front air outlet 11, the two different directions of air outlet not interfering with each other, thereby improving the air outlet efficiency and stability.

[0056] In some possible embodiments, the first end of the partition structure 21 extends to the inner cavity of the fixed air duct 1, and the second end of the partition structure 21 extends to the front side of the fixed air duct 1, wherein: Figure 1 As shown, in the raised position, the second end of the partition structure 21 is arranged spaced apart from the fixed air duct 1 to form the front air outlet 11; as shown in Figure 2 As shown, in the lowered position, the second end of the partition structure 21 is in contact with the fixed air duct 1 to close the front air outlet 11.

[0057] When the air outlet assembly 2 is raised, the second end of the partition structure 21 is arranged spaced apart from the fixed air duct 1 to form the front air outlet 11, without the need for additional independent movable door plate or other opening and closing structure, but using the partition structure 21 itself as a component part of the front air outlet 11, thereby simplifying the overall structure; when the air outlet assembly 2 is lowered, the second end of the partition structure 21 is in contact with the fixed air duct 1 to close the front air outlet 11, using the form of the partition structure 21 itself to form a closed contact with the fixed air duct 1, which can close the front air outlet 11 without using a complex sealing assembly, thereby avoiding the sealing failure problem caused by component aging in the traditional sealing mode, and improving the service life of the product.

[0058] The fixed air duct 1 can be implemented in various ways. Referring to Figure 1 and Figure 4 In some possible embodiments, the fixed air duct 1 includes a seat body 15 and a cover plate 16 arranged on the top of the seat body 15, the cover plate 16 being provided with an opening penetrating through the seat body 15, and the air outlet assembly 2 and the cover plate 16 jointly defining the front air outlet 11 in the raised position. The fixed air duct 1 is divided into two independent components of the seat body 15 and the cover plate 16, wherein the cover plate 16 can be formed by a separate mold, and the structure can be flexibly adjusted according to the process requirements, thereby reducing the need for large-scale modification of the seat body 15, and reducing the mold design difficulty and manufacturing cost.

[0059] Referring to Figure 5 and Figure 7In other possible embodiments, the fixed air duct 1 includes a base body 15, and the air outlet assembly 2, when in the raised position, together with the base body 15, defines a front air outlet 11. In other words, in this embodiment, the fixed air duct 1 utilizes an integrated structure. This method of utilizing the base body 15 and the air outlet assembly 2 to form the front air outlet 11 reduces the number of components to be installed. Compared to a fixed air duct 1 composed of multiple components, this facilitates simplified installation and improves efficiency.

[0060] The air outlet assembly 2 and the partition structure 21 can be realized in a variety of ways. Figure 4 As shown, in some possible embodiments, the air outlet assembly 2 includes a movable air outlet frame 22 and a movable air duct cover plate 23 that are interlocked together, and the movable air outlet frame 22 and the movable air duct cover plate 23 are respectively provided with openings that intersect with each other, wherein the front side of the movable air duct cover plate 23 is provided with a guide portion 231 protruding from the movable air outlet frame 22, and the guide portion 231 is formed into a partition structure 21. The movable air outlet frame 22 and the movable air duct cover plate 23 can be respectively formed in independent molds, and the movable air outlet frame 22 can be designed to have a relatively regular shape, reducing the difficulty of mold design and manufacturing costs; at the same time, the guide portion 231 on the front side of the movable air duct cover plate 23 serves as the partition structure 21, and its shape and position can be flexibly adjusted according to actual needs. By optimizing the processing of the movable air duct cover plate 23 alone, the forward air outlet diversion effect can be improved without changing the mold of the entire air outlet assembly 2.

[0061] In other embodiments, Figure 7 As shown, the air outlet assembly 2 includes a movable frame 25, wherein: the inner cavity of the movable frame 25 forms the upward air outlet channel 13; and the front side wall of the movable frame 25 forms the partition structure 21. The inner cavity of the movable frame 25 forms the upward air outlet channel 13, and the front side wall of the movable frame 25 serves as the partition structure 21. This integrated construction reduces the number of parts, which is conducive to improving production efficiency. The integrated structural design also enhances the overall rigidity of the air outlet assembly 2. During the lifting movement, the movable frame 25 has higher stability, making the air outlet effect more stable and reliable.

[0062] In order to realize multiple air outlet modes, in some possible implementations, such as Figure 4 and Figure 7 As shown, a damper mechanism 241 is further provided at the upper air outlet 12, and the damper mechanism 241 is used to open or close the upper air outlet 12. By providing an openable or closable damper mechanism 241 at the upper air outlet 12, users can flexibly select a single forward air supply mode, a single upward air supply mode, or a combination of the two according to the usage scenario, thereby improving the degree of adjustment freedom of the air outlet direction and the adaptability of the air conditioner to different scenarios.

[0063] The damper mechanism 241 can be implemented in a variety of possible ways. In some embodiments, the damper mechanism 241 includes a plurality of spaced-apart blades and a blade drive motor, which is arranged on the rear side of the air outlet device to drive the blades to swing back and forth and / or left and right. The damper mechanism 241 is configured to include a plurality of spaced-apart blades and a blade drive motor that drives the blades to swing back and forth and left and right. The upward airflow direction can be adjusted by swinging the blades at multiple angles, wherein the front and back swing changes the pitch angle of the airflow, and the left and right swing widens the horizontal air supply range, avoiding regional temperature differences caused by fixed-direction air supply, and meeting airflow requirements in different scenarios.

[0064] In some possible embodiments, the air outlet device may further include a top cover plate 24 that is interlocked with the air outlet assembly 2. The air outlet assembly 2 and the top cover plate 24 are each provided with an opening that intersects with each other, and the damper mechanism 241 is provided at the opening of the top cover plate 24. This arrangement of the top cover plate 24 being independent of the air outlet assembly 2 allows maintenance of the damper mechanism 241 without disassembling the entire air outlet assembly 2.

[0065] like Figure 3 As shown, the drive mechanism 3 is disposed on the outer wall of the fixed air duct 1. The drive mechanism 3 is fixedly disposed on the fixed air duct 1, and the drive portion of the drive mechanism 3 is connected to the air outlet assembly 2. By arranging the drive mechanism 3 on the outer wall of the fixed air duct 1, on the one hand, it can avoid occupying the internal space of the fixed air duct 1, ensuring the smoothness of the air flow channel inside the air duct, and improving the air outlet efficiency and air outlet stability. On the other hand, this external installation method is easier to access, making installation and maintenance more convenient.

[0066] The drive mechanism 3 may include a mounting bracket 31, a movable bracket 32, and a drive motor 33. The mounting bracket 31 is fixedly mounted on the fixed air duct 1. The movable bracket 32 ​​can be driven by the drive motor 33 to move up and down relative to the mounting bracket 31. The movable bracket 32 ​​is connected to the air outlet assembly 2. The mounting bracket 31 is mounted on the fixed air duct 1 to provide stable support for the entire drive mechanism 3, preventing the movable bracket 32 ​​from shaking or other instability during the lifting and lowering process, thereby ensuring the stability of the air outlet assembly 2 during the lifting and lowering process.

[0067] The drive motor 33 can drive the movable bracket 32 ​​in a variety of ways. In some possible embodiments, the mounting bracket 31 is provided with a rack 34, which can be integrally formed with the mounting bracket 31 or fixed to the mounting bracket 31 by bolts, etc. The output end of the drive motor 33 is provided with a gear 35 for engaging with the rack 34. The use of a meshing transmission method between the gear 35 and the rack 34 can provide higher transmission efficiency and higher control accuracy. In addition, by controlling the air outlet assembly 2 to hover at different positions, the size of the front air outlet 11 can be changed, thereby controlling the air volume of the front air outlet.

[0068] Further, with continued reference to Figure 3 The mounting bracket 31 can be provided with a first sliding guide structure 362, and the movable bracket 32 is provided with a second sliding guide structure 361, the first sliding guide structure 362 and the second sliding guide structure 361 are in sliding cooperation, for enabling the movable bracket 32 to slide according to a preset track. The sliding guide structure can be, for example, a sliding groove and a roller cooperation, or a sliding rail and a guide rib, etc. By respectively providing the sliding guide structure on the mounting bracket 31 and the movable bracket 32, the stability of the lifting movement of the air outlet assembly 2 is improved, and the phenomenon of deviation or jamming of the air outlet assembly 2 during movement is prevented.

[0069] The air outlet of the fixed air duct 1 can also be provided with a grille structure 151. By providing the grille structure 151 at the air outlet of the fixed air duct 1, it can prevent larger particles of foreign matter from entering the inside of the air duct. In addition, the grille structure 151 can also play a preliminary guiding and uniformizing role on the airflow, making the outflowing air more soft and stable, and optimizing the air outlet experience.

[0070] According to the second aspect of the embodiments of the present disclosure, an air conditioner is also provided, which comprises the air outlet device of any one of the above and has all the beneficial effects thereof. Taking a cabinet type air conditioner as an example, the air outlet air duct provided by the present disclosure can be arranged at the top position of the air conditioner.

[0071] According to the second aspect of the embodiments of the present disclosure, a control method of an air conditioner is also provided, which is used for controlling the air conditioner of any one of the above. The upper air outlet 12 is provided with a damper mechanism 241, which can open or close the upper air outlet 12.

[0072] The control method of the air conditioner comprises: acquiring an indoor temperature value; and controlling the air outlet assembly to lift or lower to open or close the front air outlet, and controlling the damper mechanism to open or close the upper air outlet according to the acquired indoor temperature value. By acquiring the indoor temperature value and controlling the opening and closing states of the front air outlet 11 and the upper air outlet 12 according to the acquired indoor temperature value, the air conditioner can dynamically adjust the air outlet mode based on the indoor environment temperature, improve the flexible response of the air conditioner to different temperature sensing demands, and provide diversified air supply schemes.

[0073] The method can be applied to various air conditioning modes, for example, it can be applied to a cooling mode or a heating mode, which will be introduced respectively.

[0074] For the refrigeration mode: in some possible embodiments, according to the acquired indoor temperature value, the control of the lifting of the air outlet assembly to open or close the front air outlet and the control of the damper mechanism to open or close the upper air outlet include: in the refrigeration mode, when the indoor temperature is greater than a preset refrigeration temperature value, the air outlet assembly is controlled to be lifted to open the front air outlet, and the damper mechanism is controlled to open the upper air outlet. In the refrigeration mode, by setting the front air outlet 11 and the upper air outlet 12 to be opened at the same time when the indoor temperature is higher than the preset value, the air conditioner is preferentially used in the composite mode of the front straight-sending cold air and the upward auxiliary air supply, so as to quickly reduce the temperature of the human activity area.

[0075] In other possible embodiments, according to the acquired indoor temperature value, the control of the lifting of the air outlet assembly to open or close the front air outlet and the control of the damper mechanism to open or close the upper air outlet include: in the refrigeration mode, when the indoor temperature is less than or equal to a preset refrigeration temperature value, the air outlet assembly is controlled to be lowered to close the front air outlet, and the damper mechanism is controlled to open the upper air outlet. In the refrigeration mode, when the indoor temperature is below the preset value, the front air outlet 11 can be closed, and the upper air outlet 12 is kept open, so as to avoid the discomfort caused by the direct blowing of the cold air to the human body when the temperature has been reduced to below the preset value.

[0076] For the heating mode: according to the acquired indoor temperature value, the control of the lifting of the air outlet assembly to open or close the front air outlet and the control of the damper mechanism to open or close the upper air outlet include: in the heating mode, when the indoor temperature is less than a preset heating temperature value, the air outlet assembly is controlled to be lifted to open the front air outlet, and the damper mechanism is controlled to open the upper air outlet. In the heating mode, by setting the front air outlet 11 and the upper air outlet 12 to be opened at the same time when the indoor temperature is lower than the preset value, the air conditioner is preferentially used in the composite mode of the front straight-sending hot air and the upward auxiliary air supply, so as to quickly raise the temperature of the human activity area.

[0077] In other possible embodiments, according to the acquired indoor temperature value, the control of the lifting of the air outlet assembly to open or close the front air outlet and the control of the damper mechanism to open or close the upper air outlet include: in the heating mode, when the indoor temperature is less than or equal to a preset heating temperature value, the air outlet assembly is controlled to be lowered to close the front air outlet, and the damper mechanism is controlled to open the upper air outlet. In the heating mode, when the indoor temperature is below the preset value, the front air outlet 11 can be closed, and the upper air outlet 12 is kept open, so as to avoid the discomfort caused by the direct blowing of the hot air to the human body when the temperature has been raised to above the preset value.

[0078] In the detailed description above, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration specific aspects in which the disclosure can be practiced. In this regard, directional terminology, such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and other commonly used terms, are used herein for the purpose of illustration only and are not intended to be limiting. Because the described devices can be positioned in a number of different orientations, the directional terminology can be used for illustration purposes only and is not limiting. It is to be understood that other aspects can be utilized and structural or logical changes can be made without departing from the scope of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense.

[0079] It is to be understood that the features of the various aspects of the disclosure described herein can be combined with each other, unless specifically noted otherwise. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items; similarly, "at least one of' includes any and all combinations of one or more of the associated listed items.

[0080] It should be understood that, unless otherwise specifically stated and limited, the terms "joined," "attached," "mounted," "connected," "fixed," and terms of similar meaning in the embodiments of the disclosure adopted herein should be construed in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection or communication with each other; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited. The specific meaning of the above terms in this article can be understood according to the specific circumstances by those skilled in the art.

[0081] In addition, the word "over" as used in reference to a component, element, or material layer that is formed "over" or located "over" a surface in the detailed description and claims herein can be used to mean that the component, element, or material layer is positioned (e.g., placed, formed, deposited, etc.) "indirectly" over the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the word "over" as used in reference to a component, element, or material layer that is formed "over" or located "over" a surface in the detailed description and claims herein can optionally also be used to mean that the component, element, or material layer is positioned (e.g., placed, formed, deposited, etc.) "directly" over the surface, e.g., in direct contact with the surface.

[0082] Although terms such as "first", "second" and "third" may be used herein to describe various components, parts, regions, layers or sections, these components, parts, regions, layers or sections are not limited to these terms. On the contrary, these terms are only used to distinguish one component, part, region, layer or section from another component, part, region, layer or section. Therefore, without departing from the teachings of each example, the first component, part, region, layer or section mentioned in the examples described herein may also be referred to as the second component, part, region, layer or section. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one such feature. In the description herein, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0083] It should be understood that spatially relative terms, such as "above," "upper," "below," and "lower," are used herein to describe the relationship of one element to another element shown in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as being "above" or "upper" relative to another element would then be "below" or "lower" relative to the other element. Thus, the term "above" encompasses both above and below orientations, depending on the spatial orientation of the device. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0084] Furthermore, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, the use of the word exemplary is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies to A or B" is intended to mean any of the natural inclusive permutations. That is, if X applies to A; X applies to B; or X applies to both A and B, then "X applies to A or B" satisfies any of the aforementioned instances. Furthermore, the articles "a" and "an," as used in this application and the appended claims, are generally understood to mean "one or more," unless otherwise specified or clear from the context to refer to the singular form.

[0085] Likewise, although the present disclosure has been described and illustrated with respect to one or more implementations, equivalent alterations and modifications will become apparent to those skilled in the art that do not depart from the true spirit and scope of the disclosure. The present disclosure includes all such modifications and alterations and is limited only by the scope of the following claims. In particular regard to the various functions performed by the above described components (e.g., elements, resources, etc.), the terms (including a reference to a "means") used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the described function (e.g., a functional equivalent), even though not structurally equivalent to the disclosed structure. In addition, although a particular feature of the disclosure can have been disclosed with respect to only one of several implementations, other implementations can include the particular feature. For example, the disclosure can be implemented with respect to other implementations that incorporate the particular feature, and that implement other features as disclosed herein, and each of the various implementations have a reasonable expectation of support. Furthermore, to the extent that the terms "includes", "including", "has", "have", "having", or variants thereof are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term "comprising".

[0086] Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the features of the disclosure disclosed herein. It is intended that the present disclosure be considered as including any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such steps, compositions, components, and / or elements known in the art to be appropriate. It is specifically intended that the present disclosure include all such modifications and alterations in the application, matter, and scope of the disclosure as fall within the usual practice of the art and are equated with the principles of the disclosure. The specification and examples are to be considered exemplary only, with the true scope and spirit of the disclosure being indicated by the following claims.

[0087] It is to be understood that the present disclosure is not limited to the precise construction described and shown in the drawings and that various modifications and changes can be made by those skilled in the art without departing from the scope of the present disclosure.
