Description

Technical Field

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

[0002] Currently, some air conditioners on the market are equipped with radar devices for detecting the position of people.

[0003] Such radar devices are typically equipped with rectangular radomes, which confine the electromagnetic waves emitted by the radar device to a small radiation range, severely affecting the detection performance of the radar device. Summary of the Invention

[0004] The problem solved by this invention is that existing radomes confine electromagnetic waves to a small radiation range, resulting in poor detection performance of radar devices.

[0005] To address the aforementioned problems, this invention provides a radar dome that can increase the radiation range of electromagnetic waves emitted by an air conditioning radar, thereby improving the detection performance of the air conditioning radar.

[0006] An embodiment of the present invention provides a radar dome, which is provided with an open end and a closed end. From the open end to the closed end, the area enclosed by the cross-section of the radar dome gradually decreases, and the radar dome forms a mounting cavity for accommodating an air conditioning radar.

[0007] The radome provided in this embodiment of the invention has a gradually decreasing cross-sectional area from its open end to its closed end, making it an expanded radome. In practical applications, the air conditioning radar is housed within a mounting cavity, and the electromagnetic waves it emits radiate at an angle along the sidewalls of the expanded radome, resulting in a wider radiation range and significantly improving the detection performance of the air conditioning radar.

[0008] In an optional embodiment, the radome includes multiple side plates connected end to end in the circumferential direction, with any two adjacent side plates forming an angle.

[0009] In an optional embodiment, the plurality of side plates include a first side plate and a second side plate, the first side plate and the second side plate being disposed opposite to each other, and the included angle between the first side plate and the second side plate being greater than 90° and less than 180°.

[0010] The first side plate and the second side plate are arranged opposite each other, and the included angle between the first side plate and the second side plate is an obtuse angle. In practical applications, after the radar cover is installed on the air conditioner, the first side plate and the second side plate extend in the vertical direction, that is, the flared area enclosed by the first side plate and the second side plate extends in the horizontal direction, so that the air conditioner radar can obtain a wider radiation accuracy in the horizontal direction, avoid detection blind spots, and improve the detection effect of the air conditioner radar.

[0011] In an optional embodiment, the radome further includes a base plate, wherein one end of each of the first side plate and the second side plate is connected to two opposite and parallel sides of the base plate.

[0012] In an optional embodiment, the angle between the first side plate and the second side plate and the bottom plate is greater than 90°.

[0013] In an optional embodiment, the first side plate is provided with a cable tray through which the wiring of the air conditioning radar passes.

[0014] In an optional embodiment, the mounting cavity is connected to the outside through the open end, which is rectangular and is used to cover the inner wall of the air conditioner's display panel.

[0015] In an optional embodiment, the radome further includes a mounting plate connected to the side wall of the mounting cavity, the mounting plate being used to mount the air conditioning radar.

[0016] In an optional embodiment, the mounting plate forms an angle with the plane containing the open end.

[0017] The mounting plate forms an angle with the plane containing the open end, meaning the mounting plate forms an angle with the plane containing the end wall of the open end. In practical applications, the air conditioning radar is mounted on the mounting plate, and the open end covers the air conditioning display panel. The display panel extends in a vertical plane, meaning the mounted radar forms an angle with the vertical direction and tilts downwards, allowing the air conditioning radar to accurately detect the location of a person.

[0018] The present invention also provides an air conditioner, including an air conditioner body, an air conditioner radar and the radar cover, wherein the radar cover is provided with an open end and a closed end, and the area enclosed by the cross-section of the radar cover gradually decreases from the open end to the closed end. The radar cover encloses a mounting cavity, and the air conditioner radar is housed in the mounting cavity. The open end is covered on the inner wall of the display panel of the air conditioner body.

[0024] 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.

[0025] Air conditioning radar is used to detect whether there are people in the room, their location, and the number of people. This information is then used as the basis for intelligent air conditioning control, enabling intelligent airflow. For example, the airflow is weaker in areas where people are close to the air conditioner, stronger in areas farther away, more gentle when people are sitting still, and stronger when there are many people.

[0026] Please see Figure 1 , Figure 1 The diagram shown is a structural schematic of the radar dome 100 provided in this embodiment from a first-view perspective.

[0027] The radar dome 100 provided in this embodiment is used to install an air conditioning radar and fix it to the inner wall of the air conditioner's display panel. The air conditioning radar is used to detect the position of a human body, and the detection result serves as the basis for adjusting the air conditioning's airflow direction to provide a better user experience. The radar dome 100 provided in this embodiment can increase the radiation range of the electromagnetic waves emitted by the air conditioning radar, thereby improving the detection effect of the air conditioning radar.

[0028] The radar dome 100 provided in this embodiment is provided with an open end 110 and a closed end 130. From the open end 110 to the closed end 130, the area enclosed by the cross-section of the radar dome 100 gradually decreases, that is, the radar dome 100 is a mask shape.

[0029] The radome 100 forms a mounting cavity 120, which is used to house the air conditioning radar. The open end 110 is designed to be open, meaning that the mounting cavity 120 is connected to the outside world through the open end 110. During operation, the electromagnetic waves emitted by the air conditioning radar are radiated out through the open end 110.

[0030] In practical applications, the radar dome 100 is mounted on the inner wall of the air conditioner's display panel through the open end 110. The end wall of the open end 110 is in contact with the inner wall of the air conditioner's display panel. The electromagnetic waves emitted by the air conditioner radar are radiated out through the open end 110 to detect the position of the human body.

[0031] Because the radar dome 100 is flared, electromagnetic waves radiate at an angle along the side wall of the dome, resulting in a wider radiation range and thus a wider detection range for the air conditioning radar, significantly improving the detection effect.

[0032] The radome 100 includes a base plate 121 and multiple side plates. Each side plate has a common end connected to multiple edges of the base plate 121, and the side plates are sequentially connected end-to-end in the circumferential direction. That is, the two opposite sides of one side plate are connected to two adjacent side plates. The multiple side plates and the base plate 121 together form a mounting cavity 120. Furthermore, in this embodiment, any two adjacent side plates form an angle, meaning the cross-section of the radome 100 is a polygonal structure.

[0033] In this embodiment, the multiple side plates include a first side plate 123 and a second side plate 125, which are arranged opposite to each other. In fact, the bottom plate 121 has two opposite and parallel sides, which are respectively connected to the same end of the first side plate 123 and the second side plate 125.

[0034] In practical applications, by presetting the installation angle of the radar cover 100, it is ensured that when the open end 110 of the radar cover 100 is placed on the display panel of the air conditioner, the first side plate 123 and the second side plate 125 of the radar cover 100 are spaced apart in the horizontal direction, that is, the first side plate 123 and the second side plate 125 form an electromagnetic wave radiation angle.

[0035] Please combine Figure 1 and Figure 2 , Figure 2 The diagram shown is a structural schematic of the radome 100 provided in this embodiment from a second viewpoint.

[0036] To ensure effective electromagnetic wave radiation and achieve a wider radiation range, in this embodiment, the included angle A between the first side plate 123 and the second side plate 125 is 120°. In other embodiments, depending on actual application conditions such as indoor area and air conditioner installation location, the included angle between the first side plate 123 and the second side plate 125 can be adaptively adjusted between 90° and 180°.

[0037] Furthermore, in this embodiment, in order to ensure the aesthetics of the radome 100, the plane containing the bottom plate 121 and the end face of the open end 110 is kept parallel, the angle between the first side plate 123 and the bottom plate 121 is greater than 90°, and the angle between the second side plate 125 and the bottom plate 121 is also greater than 90°.

[0038] In practical applications, when the air conditioning radar is housed in the mounting cavity 120, it is necessary to connect the air conditioning radar to the air conditioning control box. Therefore, in this embodiment, the first side plate 123 is provided with a wire passage groove 1231 for the wiring of the air conditioning radar to pass through, and the mounting cavity 120 is connected to the outside through the wire passage groove 1231.

[0039] Please continue to refer to Figure 1The radar dome 100 provided in this embodiment also includes a mounting plate 127, which is connected to multiple side walls of the mounting cavity 120 for mounting the air conditioning radar.

[0040] In reality, when the air conditioner is installed indoors, the display panel is usually in a vertical position. In this case, when the open end 110 of the radar cover 100 covers the display panel, the opening of the mounting cavity 120 points in the horizontal direction. Since the installation height of the air conditioner is usually higher than the height of the human body, if the air conditioner radar radiates electromagnetic waves in the horizontal direction, it will be unable to detect the location of the human body.

[0041] Therefore, in this embodiment, the plane containing the mounting plate 127 and the open end 110 forms an angle. That is, when the installation is completed, the mounting plate 127 forms an angle with the vertical plane. The air conditioning radar is installed on the mounting plate 127, and the air conditioning radar is tilted downwards, radiating electromagnetic waves downwards, which can detect the position of the human body.

[0042] In summary, in practical applications, the radar dome 100 provided in this embodiment has an included angle A of 120° between the first side plate 123 and the second side plate 125. The first side plate 123 and the second side plate 125 form an electromagnetic wave radiation angle with a gradually expanding opening. When the air conditioning radar is installed in the mounting cavity 120 of the radar dome 100, the electromagnetic waves emitted by the air conditioning radar can radiate to a wider range under the guiding effect of the first and second included angles, thereby accurately locating the human body and improving the detection effect of the air conditioning radar.

[0043] Please see Figure 3 , Figure 3 The image shown is a partial structural cross-sectional view of the air conditioner provided in this embodiment.

[0044] This embodiment also provides an air conditioner, which includes an air conditioner body, an air conditioner radar 210 and the aforementioned radar cover 100. The open end 110 of the air conditioner radar 210 is covered on the inner wall of the display panel 220 of the air conditioner body. The air conditioner radar 210 is housed in the mounting cavity 120 of the radar cover 100 and is used to detect indoor human information, including quantity information, location information, movement information, etc.

[0045] Because the radar dome 100 is an expanded mask structure, the included angle A between its first side plate 123 and second side plate 125 is 120°. The first side plate 123 and the second side plate 125 form an electromagnetic wave radiation angle with a gradually expanding opening. Therefore, the electromagnetic waves emitted by the air conditioning radar 210 can radiate to a wider range under the guidance of the first and second included angles, thereby accurately locating the human body and improving the detection effect.

[0046] Furthermore, since there is an angle between the mounting plate 127 of the radar dome 100 and the display panel 220, the air conditioning radar 210 is tilted downwards, which ensures that the radiated electromagnetic waves can cover the range of human activity indoors, thereby enabling accurate detection of human information.

[0047] Therefore, the air conditioner provided in this embodiment has the characteristics of higher detection accuracy and better user experience.

[0048] 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.
