Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a sweeping blade and an air conditioner. Background Technology

[0002] As living standards improve, people are paying more attention to the user experience when using air conditioners. As a result, various features have emerged on air conditioners to enhance the user experience, and zero-wind-feel mode is one of them. Undoubtedly, the zero-wind-feel mode avoids the pain of strong airflow blowing directly on people, greatly improving user comfort.

[0003] However, in the existing technology, when the air conditioner is operating in zero-wind mode, condensation usually forms on the inner walls of many places on the air conditioner casing, causing great inconvenience to users. Summary of the Invention

[0004] The problem solved by this invention is to improve the technical problem of condensation forming on multiple inner walls of the air conditioner casing during operation in zero-wind-feel mode in the prior art.

[0005] To solve the above problems, the present invention provides a sweeping blade, including a first sweeping part and a second sweeping part;

[0006] The first air-sweeping section has a first through hole, and the second air-sweeping section has a first cover.

[0007] The first sweeping section is rotatably connected to the second sweeping section so that the first sweeping section and the second sweeping section can be selectively overlapped or unfolded;

[0008] When the first sweeping part and the second sweeping part are overlapped, the first covering part covers the first through hole; when the first sweeping part and the second sweeping part are unfolded, the first covering part opens the first through hole.

[0009] The advantages of the sweeping blades provided by this invention compared to the prior art include:

[0010] When applied to an air conditioner, this sweeping blade can guide the airflow exiting the air conditioner. With the first and second sweeping sections deployed, the first cover opens the first through-hole. As the airflow is guided by the sweeping blade, it is not only guided by the first sweeping section, but some airflow also passes through the first through-hole, thus affecting the airflow direction and speed, weakening the airflow, and achieving a zero-wind-feel function. When the first and second sweeping sections overlap, the first cover covers the first through-hole, preventing airflow from passing through it. Therefore, under the guidance of the first sweeping section, the airflow is directed in one direction, ensuring smooth airflow and preventing condensation from forming on multiple inner walls inside the air conditioner. Thus, it can improve the technical problem of condensation forming on multiple inner walls of the air conditioner casing during zero-wind-feel operation in existing technologies.

Detailed Implementation

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] An embodiment of this application provides an air conditioner (not shown), which includes an indoor unit and an outdoor unit. The indoor unit is configured to be installed in a designated area to provide air conditioning to that area; the outdoor unit is configured to be installed in an area outside the designated area, and is connected to the indoor unit so that refrigerant can circulate between the indoor and outdoor units under the action of the outdoor unit. It should be noted that the air conditioning functions provided by the indoor unit include, but are not limited to: temperature regulation, humidity regulation, fresh air intake, dust removal, and airflow speed regulation.

[0037] The indoor unit contains a fan that generates airflow. This fan draws in air from a designated area, conditions the incoming air, and then directs the treated air into that area, thus improving air quality and user comfort. To ensure the airflow is directed to its intended location, the indoor unit includes a structure that guides the airflow, ensuring precise air conditioning at that specific location.

[0038] Of course, in existing technologies, to improve user comfort, structures used to guide airflow can achieve a zero-wind-feel mode. In other words, these structures can disperse the airflow, thereby changing its direction and reducing its speed, thus achieving a zero-wind-feel function. However, this method usually causes airflow to enter multiple gaps inside the air conditioner casing, resulting in condensation on the inner walls of the casing, which is extremely inconvenient for users.

[0039] In order to improve the above-mentioned technical problems, namely, to improve the technical problem that condensation is easily formed on the inner wall of the air conditioner casing in many places due to the setting of the zero wind feeling mode, the present application provides the sweeping blade 10 and the air conditioner using the sweeping blade 10.

[0040] Please refer to the following: Figure 1 and Figure 2 In the embodiments of this application, the sweeping blade 10 includes a first sweeping section 100 and a second sweeping section 200. The first sweeping section 100 has a first through hole 110, and the second sweeping section 200 has a first covering section 210. The first sweeping section 100 is rotatably connected to the second sweeping section 200 so that the first sweeping section 100 and the second sweeping section 200 can selectively overlap or unfold. The rotatable connection of the first sweeping section 100 to the second sweeping section 200 means that the first sweeping section 100 can rotate relative to the second sweeping section 200, and the rotation of the first sweeping section 100 relative to the second sweeping section 200 is in the form of flipping relative to the second sweeping section 200. This facilitates the first sweeping section 100 to move closer to the second sweeping section 200 to achieve the purpose of overlapping the first sweeping section 100 and the second sweeping section 200, and also facilitates the first sweeping section 100 to move away from the second sweeping section 200 to achieve the purpose of unfolding the first sweeping section 100 and the second sweeping section 200. When the first sweeping part 100 and the second sweeping part 200 are stacked, the first covering part 210 covers the first through hole 110; when the first sweeping part 100 and the second sweeping part 200 are unfolded, the first covering part 210 opens the first through hole 110.

[0041] As described above, when the first sweeping section 100 and the second sweeping section 200 are deployed together, the first covering section 210 opens the first through hole 110. Therefore, when the first sweeping section 100 guides the airflow, some airflow can pass through the first through hole 110, causing the airflow to flow in multiple directions, thus creating multi-directional airflow and disrupting the airflow direction. Simultaneously, the arrangement of the first sweeping section 100 and the first through hole 110 reduces the airflow velocity, thereby weakening the airflow. Based on this, a zero-wind-feel function can be achieved. Furthermore, when the first sweeping section 100 and the second sweeping section 200 are overlapped, the first covering section 210 covers the first through hole 110 to close it. Therefore, when the first sweeping section 100 guides the airflow, it can guide the airflow in one direction, allowing the airflow to flow smoothly in one direction. This prevents airflow from entering multiple gaps inside the air conditioner, thus preventing condensation from forming on multiple inner walls inside the air conditioner. Therefore, when the sweeping blade 10 is applied to an air conditioner, the technical problem of condensation forming on the inner walls of multiple parts of the air conditioner casing due to the setting of the zero-wind-feel mode can be improved.

[0042] It is worth noting that the sweeping blade 10 provided in this application can provide a zero-wind-feel function when the user requires it, and cancel the zero-wind-feel function by overlapping the first sweeping section 100 and the second sweeping section 200 when the user's need for the zero-wind-feel function is not significant, thereby improving the problem of condensation forming on multiple inner walls inside the air conditioner. In other words, the sweeping blade 10 and the air conditioner using the sweeping blade 10 can not only achieve a zero-wind-feel function, but also turn off the zero-wind-feel mode when the user does not need it, thereby improving the technical problem of condensation easily forming on multiple inner walls inside the air conditioner.

[0043] Optionally, please refer to the following: Figure 1 and Figure 3In some embodiments of this application, both the first sweeping section 100 and the second sweeping section 200 are sheet-like; this provides stable and effective guidance to the airflow and also facilitates the overlapping and unfolding of the first sweeping section 100 and the second sweeping section 200. An example can be given where the first sweeping section 100 and the second sweeping section 200 are approximately rectangular. A rotatable connecting portion 120 is provided on one side of the first sweeping section 100, and a rotatable engaging portion 230 is provided on one side of the second sweeping section 200; the rotatable connecting portion 120 and the rotatable engaging portion 230 are rotatably connected. By providing the rotatable connecting portion 120 on the side of the first sweeping section 100 and the rotatable engaging portion 230 on the side of the second sweeping section 200, the rotatable engaging of the first sweeping section 100 and the second sweeping section 200 can be achieved through the rotatable engaging of the rotatable connecting portion 120 and the rotatable engaging portion 230, thereby facilitating the unfolding and overlapping of the first sweeping section 100 and the second sweeping section 200.

[0044] Of course, in other embodiments of this application, the first sweeping part 100 and the second sweeping part 200 can also achieve rotational engagement in other ways. For example, the second sweeping part 200 is rotatably connected to the middle of the first sweeping part 100, and the second sweeping part 200 can be flipped relative to the first sweeping part 100; in this case, the second sweeping part 200 divides the first sweeping part 100 into two parts from the middle of the first sweeping part 100, and the first through hole 110 can be provided on one of the parts, so that when the second sweeping part 200 is superimposed on the part, the first through hole 110 can be covered by the first covering part 210; of course, when the second sweeping part 200 is unfolded relative to the first sweeping part 100, the first through hole 110 can be opened. Furthermore, based on this, a second sweeping section 200 can be provided on two opposite sides of the first sweeping section 100. In other words, two second sweeping sections 200 can be provided on the first sweeping section 100. At this time, a first through hole 110 can be opened on both parts of the first sweeping section 100, and the first through hole 110 on the two parts can be covered by the two second sweeping sections 200 respectively.

[0045] To facilitate the rotational engagement of the first sweeping section 100 and the second sweeping section 200, in some embodiments of this application, the rotating connecting section 120 includes a rotating shaft 121 disposed on the side of the first sweeping section 100, and the rotating engaging section 230 is provided with a mating groove 231 adapted to the rotating shaft 121; the rotating shaft 121 is rotatably disposed inside the mating groove 231. Thus, the rotational engagement of the rotating connecting section 120 and the rotating engaging section 230 can be achieved through the rotational engagement of the rotating shaft 121 and the mating groove 231. It should be understood that in other embodiments of this application, the arrangement of the rotating connecting section 120 and the rotating engaging section 230 can be interchanged; in other words, the rotating engaging section 230 includes a rotating shaft 121 disposed on the second sweeping section 200, and the rotating connecting section 120 is provided with a mating groove 231 adapted to the rotating shaft 121, etc.

[0046] In some embodiments of this application, the rotating shaft 121 is formed as follows: a through hole 122 is formed on one side of the sheet-like first sweeping portion 100, and the rotating shaft 121 is formed at a position away from the middle of the first sweeping portion 100 via the through hole 122. Of course, in other embodiments of this application, the rotating shaft 121 can also be welded or integrated onto the side of the first sweeping portion 100.

[0047] In other embodiments of this application, the rotational connection between the rotational connecting portion 120 and the rotational mating portion 230 can be formed in other ways. For example, the rotational connecting portion 120 includes a spherical structure, and correspondingly, the rotational mating portion 230 is provided with a spherical groove adapted to the spherical structure. The cooperation between the spherical structure and the spherical groove can realize the rotational engagement between the rotational connecting portion 120 and the rotational mating portion 230.

[0048] It is worth noting that in some embodiments of this application, one of the first swing section 100 and the second swing section 200 can be rotatably coupled with the air outlet frame of the air conditioner. This allows for convenient adjustment of the angle of the first swing section 100 relative to the airflow direction by rotating either the first swing section 100 or the second swing section 200 relative to the air outlet frame, thereby facilitating the adjustment of the air outlet direction. The example of the first swing section 100 rotatably coupled with the air outlet frame will be used for illustration. To simplify the control method of the first swing section 100 and the second swing section 200, the rotation control between the first swing section 100 and the second swing section 200 is independent of the rotation control between the first swing section 100 and the air outlet frame. In other words, the rotation of the first swing section 100 relative to the air outlet frame can be controlled independently, and the rotation of the second swing section 200 relative to the first swing section 100 can also be controlled independently, thereby reducing the control difficulty of the first swing section 100 and the second swing section 200.

[0049] The rotation control method between the first sweeping section 100 and the second sweeping section 200 can be that a motor is integrated on the second sweeping section 200 or the first sweeping section 100, and the second sweeping section 200 is rotated relative to the first sweeping section 100 by a through-hole motor.

[0050] In some embodiments of this application, the first through-holes 110 are provided on the first sweeping section 100, and the multiple first through-holes 110 are arranged at intervals on the first sweeping section 100; when the first sweeping section 100 and the second sweeping section 200 are superimposed, the first covering section 210 covers the multiple through-holes. In other words, the multiple first through-holes 110 can be closed by covering them with one first covering section 210, and similarly, the multiple first through-holes 110 can be opened by moving one first covering section 210 away from the first through-holes 110. Therefore, the methods of covering and opening the first through-holes 110 can be simplified. It should be understood that in some embodiments of this application, multiple first covering sections 210 can also be provided on the second sweeping section 200, so that the multiple first covering sections 210 respectively cover the multiple first through-holes 110. In the case of providing multiple first covering parts 210, the multiple first covering parts 210 can correspond one-to-one with the multiple first through holes 110, so that one first covering part 210 covers one first through hole 110; or one first covering part 210 can correspond to multiple first through holes 110, that is, one first covering part 210 can cover multiple first through holes 110.

[0051] Optionally, the first covering portion 210 is integrally formed with the second sweeping portion 200. In other words, when the second sweeping portion 200 is sheet-like, the first covering portion 210 can be considered as a part of the second sweeping portion 200 used to cover the first through hole 110. Based on this, the entire second sweeping portion 200 can also be considered as a single first covering portion 210, that is, multiple first through holes 110 can be covered by one first covering portion 210. Of course, it can also be considered that the second sweeping portion 200 has multiple first covering portions 210, each of which corresponds to a multiple first through hole 110, so that each first covering portion 210 can cover one or more first through holes 110.

[0052] It should be noted that in other embodiments of this application, the first covering portion 210 can be disposed on the second sweeping portion 200 in other ways. That is, with the second sweeping portion 200 having a sheet-like structure, the first covering portion 210 can be additionally disposed on the sheet-like second sweeping portion 200. For example, multiple first covering portions 210 can be welded onto the second sweeping portion 200, and when the first covering portion 210 covers the first through hole 110, the first covering portion 210 extends into the first through hole 110. Another example is that the first covering portion 210 can be bonded to the second sweeping portion 200, and when the first sweeping portion 100 and the second sweeping portion 200 are overlapped, the first covering portion 210 is sandwiched between the second sweeping portion 200 and the first sweeping portion 100, etc.

[0053] In some embodiments of this application, a first guide slope 140 is provided on the side of the first sweeping section 100, and the thickness of the first sweeping section 100 gradually increases from the side towards the center. The first guide slope 140 guides the airflow along the first sweeping section 100, improving the smoothness of airflow and ensuring effective airflow guidance. When the first sweeping section 100 and the second sweeping section 200 are overlapped, the first guide slope 140 is located on the side of the first sweeping section 100 away from the second sweeping section 200. Therefore, when the first sweeping section 100 and the second sweeping section 200 are overlapped, the overall thickness of the sweeping blade 10 on its side can be reduced, thereby preventing excessive thickness of the sweeping blade 10 from affecting airflow. Please refer to the relevant documentation. Figure 4 The second sweeping section 200 has a second guide slope 240 on its side, and the thickness of the second sweeping section 200 gradually increases from the side towards its center. The second guide slope 240 guides the airflow along the second sweeping section 200, improving airflow smoothness and ensuring effective airflow guidance. When the first sweeping section 100 and the second sweeping section 200 are overlapped, the second guide slope 240 is located on the side of the second sweeping section 200 away from the first sweeping section 100. Therefore, when the first sweeping section 100 and the second sweeping section 200 are overlapped, the overall thickness of the sweeping blade 10 on its side can be reduced, thereby preventing excessive thickness of the sweeping blade 10 from affecting airflow.

[0054] It should be understood that in some embodiments of this application, the first guide slope 140 or the second guide slope 240 may be omitted. In other words, it can be stated that the first sweeping part 100 is provided with the first guide slope 140, and / or the second sweeping part 200 is provided with the second guide slope 240. Of course, in other embodiments of this application, the first guide slope 140 and the second guide slope 240 may be omitted simultaneously.

[0055] In some embodiments of this application, in conjunction with reference to Figure 4 The first sweeping section 100 is flipped relative to the second sweeping section 200, such that when the first sweeping section 100 and the second sweeping section 200 are deployed, the angle formed between the first sweeping section 100 and the second sweeping section 200 is greater than 0° and less than or equal to 180°. In other words, as long as the first sweeping section 100 and the second sweeping section 200 form an angle greater than 0°, they can be considered deployed. Of course, to prevent the second sweeping section 200 from affecting the airflow guidance of the first sweeping section 100, the second sweeping section 200 can rotate relative to the first sweeping section 100 by a large angle, such as 60°, 75°, 90°, 105°, 120°, 135°, or 150°. In this case, the second sweeping section 200 can be rotated to a position parallel to the direction of airflow from the outlet frame, thereby preventing the second sweeping section 200 from affecting the outlet airflow. Since the angle between the second sweeping section 200 and the first sweeping section 100 is greater than 0° and less than or equal to 180° when the second sweeping section 200 and the first sweeping section 100 are deployed, the first sweeping section 100 can be rotated relative to the air outlet frame to form any angle with the air outlet direction, and the second sweeping section 200 can be rotated relative to the first sweeping section 100 to make the second sweeping section 200 parallel to the air outlet direction.

[0056] It should be noted that in the first sweeping section 100 and the second sweeping section 200, the first sweeping section 100 is mainly used to guide the airflow, and the second sweeping section 200 is mainly used to cover the first through hole 110 on the first sweeping section 100. In some embodiments of this application, when the user requires a zero-wind-feel function, the first sweeping section 100 and the second sweeping section 200 can be controlled to unfold. In this case, the second sweeping section 200 needs to be adjusted to be parallel to the airflow direction to prevent the second sweeping section 200 from affecting the airflow and thus affecting the realization of the zero-wind-feel function.

[0057] Of course, please refer to the following: Figure 4In some other embodiments of this application, the second sweeping part 200 is provided with a second through hole 220, and the first sweeping part 100 is provided with a second covering part 130. When the first sweeping part 100 and the second sweeping part 200 are stacked, the second covering part 130 covers the second through hole 220; when the first sweeping part 100 and the second sweeping part 200 are unfolded, the second covering part 130 opens the second through hole 220.

[0058] It should be noted that the first sweeping section 100 and the second sweeping section 200 can be unfolded until the included angle between them is 180°, making them approximately level and thus jointly guiding the airflow. In this case, since the first sweeping section 100 has a first through hole 110 and the second sweeping section 200 has a second through hole 220, both the first sweeping section 100 and the second sweeping section 200 can achieve zero-wind-feel functionality, while also solving the problem of the second sweeping section 200 affecting the air outlet. Furthermore, since the first sweeping section 100 and the second sweeping section 200 are unfolded at 180°, the air-receiving area of ​​the sweeping blades 10 can be increased, thereby increasing the weakening effect on the airflow velocity, thus achieving zero-wind-feel functionality even at high wind speeds.

[0059] Furthermore, when the first sweeping section 100 and the second sweeping section 200 overlap, the first through hole 110 can be covered by the first covering section 210 and the second through hole 220 can be covered by the second covering section 130, thereby simultaneously closing the first through hole 110 and the second through hole 220, so that the sweeping blade 10 becomes a general guide vane to guide the airflow in one direction.

[0060] Optionally, in some embodiments of this application, there are multiple first through holes 110 and multiple second through holes 220. The first covering portion 210 includes multiple first covering portions 210; the multiple first covering portions 210 and multiple second through holes 220 are alternately disposed on the second sweeping portion 200. The second covering portion 130 includes multiple second covering portions 130; the multiple second covering portions 130 and multiple first through holes 110 are alternately disposed on the first sweeping portion 100.

[0061] It should be noted that the first covering portion 210 can be formed as follows: a plurality of spaced-apart second through holes 220 are formed on the sheet-like second sweeping portion 200, and the first covering portion 210 can be formed between any two adjacent second through holes 220. Similarly, the second covering portion 130 can be formed as follows: a plurality of spaced-apart first through holes 110 are formed on the sheet-like first sweeping portion 100, and the second covering portion 130 can be formed between any two adjacent first through holes 110.

[0062] In summary, the sweeping blade 10 and the air conditioner using the sweeping blade 10 provided in this embodiment can open the first through hole 110 when the first sweeping section 100 and the second sweeping section 200 are deployed relative to each other. Therefore, when the first sweeping section 100 guides the airflow, some airflow can pass through the first through hole 110, causing the airflow to flow in multiple directions, thus forming multi-directional airflow and disrupting the airflow direction. Simultaneously, the arrangement of the first sweeping section 100 and the first through hole 110 can reduce the airflow velocity, thereby weakening the airflow. Based on this, a zero-wind-feel function can be achieved. Furthermore, when the first sweeping section 100 and the second sweeping section 200 overlap, the first covering section 210 covers the first through hole 110 to close it. Therefore, when the first sweeping section 100 guides the airflow, it can guide the airflow in one direction, allowing the airflow to flow smoothly in one direction. This prevents the airflow from entering multiple gaps inside the air conditioner, thereby preventing condensation from forming on multiple inner walls inside the air conditioner. Therefore, when this sweeping blade 10 is applied to an air conditioner, it can improve the technical problem in the prior art where condensation easily forms on multiple inner walls inside the air conditioner casing due to the zero-wind-feel mode.

[0063] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
