Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and more particularly to air outlet devices and air conditioners. Background Technology

[0002] Portable air conditioners are a niche category in the air conditioning industry. In some overseas countries, the labor cost for air conditioner installation has always been higher than the price of the air conditioner itself. Therefore, portable air conditioner prototypes have always been popular with overseas users. At the same time, due to the rise of self-driving tours in recent years, portable small-sized air conditioner units have gradually become popular. However, since portable air conditioners are still a niche product, there is relatively little research on them, resulting in serious product homogenization and a lack of distinctive features.

[0003] In related technologies, the air volume and direction are adjusted by controlling the opening and angle of the air duct opening through two air guide vanes. While this solution achieves the desired effect, size limitations restrict the air guide angle, resulting in a small air delivery angle that is fixed within a 30°~40° range directly in front. Furthermore, the small air vents in existing solutions fail to reach people on the sides, resulting in a small air delivery area. Portable air conditioners are typically used in multi-person camping and dining settings, and such a small air delivery range cannot meet user needs. The aforementioned solution, using two sets of air guide vanes, has a simple structure, a single mode, and a single air delivery direction, leading to poor performance. Additionally, the use of multiple synchronous motors increases costs. Utility Model Content

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0032] In this disclosure, unless otherwise stated, the directional terms "left," "right," "front," and "rear" are defined based on the actual direction of use of the relevant components, as detailed in the following references. Figure 4 The directions indicated are for ease of explanation in conjunction with the accompanying drawings and do not actually restrict the directions. "Inner" and "outer" refer to the inner and outer contours of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and do not indicate sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0033] Due to size limitations, portable air conditioners in related technologies all adopt the traditional single-outlet air supply form. Their fan design and capacity have not been significantly improved. Air supply usually relies on a single large air guide plate to adjust the air direction, resulting in a limited air guide angle and a small air supply area. At the same time, the use of multiple synchronous motors to control the opening and closing of the air guide plate results in high costs.

[0034] Therefore, such as Figures 1 to 9 As shown, this disclosure provides an air outlet device, which may include a duct housing 1 and a fan wheel 3 disposed within the duct housing 1. In embodiments of this disclosure, the fan wheel 3 may be a multi-bladed centrifugal fan wheel. The duct housing 1 has a first air outlet 11 and a second air outlet 12. A first damper 21 and a second damper 22 are provided near one of the air outlets. One of the first damper 21 and the second damper 22 is rotatable, while the other is slidable, so as to selectively allow air to be discharged from at least one of the first air outlet 11 and the second air outlet 12. This disclosure includes an embodiment in which the first damper 21 rotates to open or close the first air outlet 11, and the second damper 22 slides to open or close the second air outlet 12. In this embodiment, when the first damper 21 is in the open state, it does not affect the air discharge from the second air outlet 12, thereby achieving simultaneous air discharge from the first air outlet 11 and the second air outlet 12. This disclosure also includes an embodiment in which the first damper 21 rotates to open the first air outlet 11, and the first damper 21 rotates and the sliding second damper 22 cooperates to close the second air outlet 12. The latter will be described in detail below.

[0035] Through the above technical solution, this air outlet device adopts a multi-outlet design, using a rotating and sliding door to control airflow in various directions, providing multiple air delivery capabilities. This allows different users to experience different airflow sensations, effectively catering to every user group in small spaces such as tents and RVs. The air outlet device can increase the air delivery range to 90°~120°, achieving full-enclosed air delivery when placed against a wall. The multi-outlet structure reduces the outlet dynamic pressure loss, minimizing overall pressure drop and increasing circulating airflow. Lower pressure drop also reduces the motor drive shaft power, lowering overall unit power. The smaller outlet dynamic pressure loss also results in lower airflow noise, reducing overall unit noise.

[0036] Among them, reference Figure 5 , Figure 6The first air damper 21 and the second air damper 22 are provided near the second air outlet 12. The duct housing 1 may have a first volute tongue 101 and a second volute tongue 102, with the ends of the first volute tongue 101 and the second volute tongue 102 arranged at intervals to form the first air outlet 11. The second volute tongue 102 has an arc-shaped segment 1022 and a flat segment 1021 connected to the arc-shaped segment 1022, and the second air outlet 12 is opened on the flat segment 1021. The first air outlet 11 and the second air outlet 12 are arranged at an angle to each other. In the embodiments of this disclosure, the first air outlet 11 and the second air outlet 12 are arranged at 90° to each other, with the first air outlet 11 located on the front side of the air outlet device and the second air outlet 12 located on the left side of the air outlet device. This disclosure can control the air outlet position and the air volume of different air outlets by controlling the positions of the first air damper 21 and the second air damper 22, so as to adjust the airflow speed and wind feel of the air outlet device, allowing people in different directions to experience different wind conditions.

[0037] As an exemplary embodiment of this disclosure, reference is made to Figure 2 , Figure 5 , Figure 6 The duct housing 1 may have an end face 103 connecting the ends of the first volute tongue 101 and the second volute tongue 102. A first side of the first damper 21 is rotatably mounted between the two opposing end faces 103, and a second side can overlap the connecting end 1010 of the first volute tongue 101, thus dividing the cavity between the first volute tongue 101 and the second volute tongue 102 into a first air outlet chamber 201 and a second air outlet chamber 202. The first air outlet chamber 201 is connected to the first air outlet 11, and the second air outlet chamber 202 is connected to the second air outlet 12. By adjusting the positions of the first damper 21 and the second damper 22, the two dampers can open or close the air outlets, thereby adjusting the air outlet position and air volume.

[0038] Among them, reference Figure 7 The air outlet device may include a first driving member 24 and a rotating shaft 23 connected to the output end of the first driving member 24. The first side of the first damper 21 is fixed on the rotating shaft 23. The first driving member 24 drives the first damper 21 to rotate through the rotating shaft 23. When the first driving member 24 drives the first damper 21 to rotate to the connecting end 1010 of the first volute tongue 101, the first air outlet 11 is closed; when the first driving member 24 drives the first damper 21 to rotate to a gap between it and the connecting end 1010, the first air outlet 11 is opened.

[0039] Furthermore, referring to Figure 6The rotating shaft 23 can be set at a position near the first air outlet 11 on the planar section 1021. The first damper 21 rotates around the position near the first air outlet 11 on the planar section 1021, so that it can move away from the second air outlet 12 when it is close to the first air outlet 11, and move closer to the second air outlet 12 when it is far away from the first air outlet 11, so as to adjust the air outlet conditions of the two air outlets.

[0040] According to an exemplary embodiment of this disclosure, referring to Figure 5 , Figure 8 The planar segment 1021 may include a first planar segment for forming the second air outlet 12 and a second planar segment 7 extending away from the first air outlet 11 beyond the arc-shaped segment 1022. The second planar segment 7 has a slide rail 71 for the second damper 22 to slide back and forth, and the second damper 22 at least partially closes the second air outlet 12. In the embodiments of this disclosure, the first damper 21 cannot completely cover the second air outlet 12. Therefore, by setting the second damper 22 to slide back and forth along the slide rail 71 of the second planar segment 7, the second air outlet 12 formed on the first planar segment can be at least partially closed or the second air outlet 12 can be opened. Specifically, the second damper 22 and the first damper 21 can together completely cover the second air outlet 12.

[0041] Furthermore, referring to Figure 9 The second damper 22 may have racks 221 on both sides of its sliding direction. The air outlet device may include a second drive member 25 and a gear 26 mounted on the output end of the second drive member 25. The gear 26 meshes with the rack 221, and the second drive member 25 drives the second damper 22 to slide back and forth along the slide rail 71 through the gear 26 and the rack 221. This disclosure does not limit the drive structure of the second damper 22, as long as it can drive the second damper 22 to slide back and forth along the slide rail 71.

[0042] In embodiments of this disclosure, the air outlet device may have a first air outlet state, a second air outlet state, and a third air outlet state. In the first air outlet state, refer to... Figure 2 The first damper 21 is attached to the connecting end 1010 of the first volute tongue 101, and the second damper 22 slides away from the second air outlet 12. The first air outlet 11 is closed, and only the second air outlet 12 discharges air, meaning the air outlet device only supplies air to the left. In the second air outlet state, refer to... Figure 3 The first damper 21 is coplanar with the planar section 1021, and the second damper 22 slides towards the second air outlet 12. The first damper 21 and the second damper 22 together close the second air outlet 12, and only the first air outlet 11 outlets air, that is, the air outlet device only supplies air to the front side; in the third air outlet state, refer to Figure 4The first damper 21 and the planar segment 1021 of the second volute tongue 102 are arranged at an angle to each other, and there is a gap between the first damper 21 and the connecting end 1010. The second damper 22 slides away from the second air outlet 12, and air is discharged from both the first air outlet 11 and the second air outlet 12. The smaller the angle between the first damper 21 and the planar segment 1021 of the second volute tongue 102, the smaller the air volume of the second air outlet 12 and the larger the air volume of the first air outlet 11; conversely, the larger the angle between the first damper 21 and the planar segment 1021 of the second volute tongue 102, the larger the air volume of the second air outlet 12 and the smaller the air volume of the first air outlet 11. By adjusting the angle and position of the first damper 21 and the second damper 22, the air outlet device can have three different air discharge states, improving the user experience.

[0043] Specifically, refer to Figure 4 In the third air outlet state, the angle between the first damper 21 and the plane section 1021 can be α, where 10°≤α≤30°. The value of α can be adjusted according to the air volume requirements of the two air outlets. α should not be too large or too small. If α is too large, it will affect the air supply of the first air outlet 11; if α is too small, it will affect the air supply of the second air outlet 12.

[0044] In this disclosure, such as Figure 6 As shown, the first volute tongue 101 has a straight section 1011 and a volute tongue section 1012 connected to each other. The volute tongue section 1012 is constructed as two layers arranged at intervals along the air outlet direction. The two layers of volute tongue sections 1012 are respectively provided with interconnected openings 1013. The openings 1013 with corresponding positions are interconnected and form a noise reduction cavity, which can unload the high negative pressure area of ​​the volute tongue, while ensuring the suction of high-speed airflow and reducing the air supply noise of the whole machine.

[0045] In some embodiments, refer to Figure 6 A first grille 61 may be provided at the first air outlet 11; and / or a second grille 62 may be provided at the second air outlet 12. The grilles mainly serve to protect the air conditioning equipment and prevent dust and debris from entering from the air outlets.

[0046] According to the second aspect of this disclosure, reference is made to Figure 4 Furthermore, an air conditioner is provided, which may include a housing 5, an evaporator 4 installed within the housing 5, and an air outlet device provided in this disclosure. An air inlet 13 is formed on the rear side of the housing 5. The evaporator 4 can drive the airflow drawn in through the air inlet 13 to flow through the evaporator 4 for heat exchange and then flow out from the first air outlet 11 and / or the second air outlet 12. This air conditioner has the same advantages over the prior art as the air outlet device described above, which will not be repeated here.

[0047] Specifically, the air conditioner can be a portable air conditioner, or it can be extended to an integrated air conditioner. Specifically, it can be used for RV air conditioners, window air conditioners, and floor-standing air conditioners. Among them, portable air conditioners are mainly used in scenarios where the air conditioner's position needs to be adjusted, such as portable air conditioners needed for RV road trips, tent air conditioners, and household air conditioners that do not require installation.

[0048] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0049] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0050] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0051] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on 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 term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0052] 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. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0053] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0054] Furthermore, the term “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 compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept 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 A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0055] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure.
