Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning devices, and in particular to a fan structure and an air conditioning device. Background Art

[0002] As a common air conditioning household appliance that relies on air flow movement to function, the performance parameter values ​​of air purifiers are largely directly determined by the air intake volume of the product. Therefore, how to efficiently increase the air intake volume of the product is a common technical problem in the industry. How to solve this problem has very important research value.

[0003] Traditional air purifiers generally increase the air intake by improving the fan power. However, the increase in fan power is often accompanied by an increase in negative effects such as product power consumption, operating noise, and body vibration, which is not conducive to the promotion and application of the product. Summary of the invention

[0004] Based on this, in order to address the problem that traditional air purifiers increase the air intake volume by improving the fan power, resulting in high power consumption, high operating noise and body shaking, which is not conducive to the promotion and application of the product, a fan structure and an air conditioning device are proposed. When in use, the fan structure and the air conditioning device can increase the air intake volume while avoiding increasing the power consumption and operating noise of the equipment, and can also avoid body shaking.

[0005] The specific technical solutions are as follows:

[0006] On the one hand, the present application relates to a fan structure, comprising a fan blade assembly and an air inlet panel, wherein the air inlet panel is connected to the fan blade assembly, and the air inlet panel is arranged toward the air inlet end of the fan blade assembly;

[0007] Wherein, the air inlet panel is arranged to be movable in a direction away from the fan blade assembly so that an air inlet is formed between the air inlet end of the fan blade assembly and the air inlet panel, and the air inlet area of ​​the air inlet is positively correlated with the distance between the air inlet panel and the air inlet end of the fan blade assembly; or

[0008] An air inlet is formed between the air inlet panel and the air inlet end of the fan blade assembly, and the air inlet panel is configured to be movable relative to the fan blade assembly in a direction of expanding or reducing the air inlet to adjust the air inlet area of ​​the air inlet.

[0009] When the above-mentioned fan structure is in use, the air inlet panel can be driven to move in a direction away from the fan blade assembly so that an air inlet is formed between the air inlet end of the fan blade assembly and the air inlet panel. At this time, the air inlet at the lower left and right edges of the active air suction of the fan blade assembly enters the fan blade assembly. When the air intake volume needs to be adjusted, it is only necessary to adjust the distance between the air inlet panel and the air inlet end of the fan blade assembly. The larger the distance between the air inlet panel and the air inlet end of the fan blade assembly, the larger the air inlet area of ​​the air inlet and the corresponding air intake volume; or an air inlet is formed between the air inlet panel and the air inlet end of the fan blade assembly. When the air intake volume needs to be adjusted, it is only necessary to drive the air inlet panel to move relative to the fan blade assembly in the direction of expanding or reducing the air inlet. In this way, adjusting the air intake volume by adjusting the size of the air inlet area of ​​the air inlet can avoid increasing the power consumption of the equipment and the noise of equipment operation, and at the same time can avoid the shaking of the fuselage.

[0010] The technical solution is further described below:

[0011] In one embodiment, the fan blade assembly includes a mounting base and a fan blade, the fan blade is connected to the mounting base, the air inlet end of the fan blade faces the air inlet panel, the air inlet panel is movably connected to the mounting base, and the air inlet end of the fan blade and the air inlet panel form the air inlet.

[0012] In one of the embodiments, a driving mechanism is further included, and the driving mechanism is used to drive the air inlet panel to move relative to the wind blade assembly.

[0013] In one embodiment, the driving mechanism includes a driving member and a connecting rod, one end of the connecting rod is rotatably connected to the driving member, and the other end of the connecting rod is connected to the air inlet panel. The driving member drives the connecting rod to rotate and the connecting rod drives the air inlet panel to move relative to the mounting base.

[0014] In one embodiment, the driving member includes a motor and a crank bracket connected to the motor, and the crank bracket is rotatably connected to the connecting rod.

[0015] In one embodiment, the number of the air inlet panels is at least two, and the at least two air inlet panels are arranged along the circumference of the mounting base. The number of the connecting rods is at least two, and the crank bracket includes a mounting body connected to the motor and cranks arranged at intervals along the circumference of the mounting body, and one crank corresponds to one connecting rod and can be rotatably connected.

[0016] In one embodiment, all the air inlet panels are arranged to form an installation space having an opening, the fan blades are arranged in the installation space, and the air outlet ends of the fan blades face the opening.

[0017] In one of the embodiments, the mounting base is formed with a slide groove, and the air inlet panel is formed with a sliding portion, and the sliding portion is slidably matched with the slide groove.

[0018] In one of the embodiments, a slider is further included, the sliding portion is connected to the slider, and the slider is slidably matched with the sliding groove.

[0019] In one of the embodiments, an annular filter is further included, and the annular filter is sleeved on the air inlet end of the fan blade.

[0020] In one embodiment, the fan blade is a centrifugal fan blade.

[0021] On the other hand, the present application also relates to an air conditioning device, comprising the fan structure in any of the aforementioned embodiments.

[0022] When the above-mentioned air conditioning device is in use, the air inlet panel can be driven to move in a direction away from the fan blade assembly so that an air inlet is formed between the air inlet end of the fan blade assembly and the air inlet panel. At this time, the air inlet at the lower left and right edges of the active air suction of the fan blade assembly enters the fan blade assembly. When the air intake volume needs to be adjusted, it is only necessary to adjust the distance between the air inlet panel and the air inlet end of the fan blade assembly. The larger the distance between the air inlet panel and the air inlet end of the fan blade assembly, the larger the air inlet area of ​​the air inlet and the corresponding air intake volume; or an air inlet is formed between the air inlet panel and the air inlet end of the fan blade assembly. When the air intake volume needs to be adjusted, it is only necessary to drive the air inlet panel to move relative to the fan blade assembly in the direction of expanding or reducing the air inlet. In this way, adjusting the air intake volume by adjusting the size of the air inlet area of ​​the air inlet can avoid increasing the power consumption of the equipment and the noise of equipment operation, and at the same time can avoid the shaking of the fuselage.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0039] Air conditioning devices such as air conditioners, air purifiers and fans are generally equipped with corresponding fan structures, which automatically draw air through the fan structure. The performance parameter values ​​of the air conditioning device are directly determined by the air intake volume of the fan structure to a large extent. In the fan structure of a traditional air conditioning device, multiple air inlet holes are generally opened on the air inlet panel, and the wind is introduced into the fan along the air inlet holes through the fan. Therefore, when it is necessary to increase the air intake volume, the traditional air conditioning device can only increase the fan power. However, when the fan power is increased, the air conditioning device not only consumes more power during use, but also generates noise and body shaking problems, which affects the promotion and application of the product.

[0040] Based on this, the present application proposes a fan structure 10, which can increase the air intake volume while avoiding increasing the power consumption of the equipment and the operating noise of the equipment, and can also avoid the shaking of the fuselage when in use.

[0041] Please refer to Figures 1 to 3 In one embodiment, a fan structure 10 includes a fan blade assembly 100 and an air inlet panel 200 . The air inlet panel 200 is connected to the fan blade assembly 100 , and the air inlet panel 200 is arranged toward the air inlet end of the fan blade assembly 100 .

[0042] Please refer to Figure 4 , Figure 5 and Figure 7The fan blade assembly 100 includes a fan blade 120 and a mounting base 110. There are at least two air inlet panels 200. The air inlet panels 200 are movably connected to the mounting base 110 and arranged along the circumference of the mounting base 110. The at least two air inlet panels 200 surround and form an installation space 700 having an opening 710. The fan blade 120 is arranged in the installation space 700, and the air outlet end 124 of the fan blade faces the opening 710. In this way, the fan blade 120 takes in air from the circumferential direction of the fan blade and discharges air from the axial direction. Please refer to Figure 3 , the fan blade 120 can be a centrifugal fan blade 120.

[0043] Please refer to Figure 2 and Figure 3 In some embodiments, the fan blade assembly 100 further includes an air outlet grille 130 , and the air outlet grille 130 is disposed at the air outlet end 124 of the fan blade.

[0044] Please refer to Figure 2 and Figure 3 In some embodiments, the fan structure 10 further includes an annular filter 400, which is sleeved on the air inlet end 122 of the fan blade. In this way, the wind is first filtered by the annular filter 400 before entering the fan blade 120. Optionally, the annular filter 400 can be an annular filter screen.

[0045] Please refer to Figure 5 and Figure 6 In some embodiments, the mounting base 110 is formed with a slide groove 112, and the air inlet panel 200 is formed with a sliding portion 210, and the sliding portion 210 is slidably matched with the slide groove 112. In this way, the slide groove 112 can play a role of limiting and guiding, and the air inlet panel 200 can move on a preset path, thereby improving the reliability of the movement of the air inlet panel 200.

[0046] Please refer to Figure 4 and Figure 7 In some embodiments, the fan structure 10 further includes a slider 600 , the sliding portion 210 is connected to the slider 600 , and the slider 600 is slidably matched with the slide groove 112 .

[0047] Please refer to Figure 5 and Figure 7 Taking four air inlet panels 200 as an example, the mounting base 110 is a circular plate, the air inlet panel 200 is an arc-shaped plate, and the four air inlet panels 200 are arranged along the circumference of the mounting base 110 and surround a columnar mounting space 700 .

[0048] In some embodiments, please refer to Figure 1 and Figure 5 Before the fan structure 10 is started, the air inlet panel 200 covers or envelops the air inlet end of the fan blade assembly 100, and wind cannot enter the fan blade assembly 100. Figure 2 and Figure 7 When the fan structure 10 is started, the air inlet panel 200 is configured to be movable in a direction away from the fan blade assembly 100 so that an air inlet 300 is formed between the air inlet end of the fan blade assembly 100 and the air inlet panel 200. At this time, the wind enters the fan blade assembly 100 along the air inlet 300 under the action of the fan blade assembly 100. Further, the air inlet area of ​​the air inlet 300 is positively correlated with the distance between the air inlet panel 200 and the air inlet end of the fan blade assembly 100; in other words, when the air inlet volume needs to be adjusted, it is only necessary to adjust the distance between the air inlet panel 200 and the air inlet end of the fan blade assembly 100, that is, to drive the air inlet panel 200 to move relative to the fan blade assembly 100. In this way, adjusting the air inlet volume by adjusting the size of the air inlet area of ​​the air inlet 300 can avoid increasing the power consumption of the equipment and the noise of the equipment operation, and can also avoid the shaking of the fuselage. Furthermore, compared with the solution in which the fan structure of a traditional air conditioning device has multiple air inlet holes on the air inlet panel and the wind is introduced into the fan along the air inlet holes through the fan, in this embodiment, the air inlet panel 200 is driven to move in a direction away from the fan blade assembly 100 to form an air inlet 300 between the air inlet end of the fan blade assembly 100 and the air inlet panel 200, and the air inlet area of ​​the air inlet 300 is relatively large, and thus the air inlet area is also relatively large.

[0049] In some other embodiments, an air inlet 300 is formed between the air inlet panel 200 and the air inlet end of the fan assembly 100. When in use, under the action of the fan assembly 100, wind enters the fan assembly along the air inlet 300; further, the air inlet panel 200 is configured to be movable relative to the fan assembly 100 in the direction of expanding or reducing the air inlet 300 to adjust the air inlet area of ​​the air inlet 300. In this way, when the air intake volume needs to be adjusted, it is only necessary to drive the air inlet panel 200 to be configured to be movable relative to the fan assembly 100 in the direction of expanding or reducing the air inlet 300. In this way, adjusting the air intake volume by adjusting the size of the air inlet area of ​​the air inlet 300 can avoid increasing the power consumption of the device and the noise of the device operation, and can also avoid the shaking of the fuselage.

[0050] It should be pointed out that in the aforementioned embodiments, the air inlet 300 is enclosed to form an effective air inlet area, and the air inlet area of ​​the air inlet 300 refers to the area of ​​the air inlet area.

[0051] Please refer to Figure 3 and Figure 4 In some embodiments, the fan structure 10 further includes a driving mechanism 500 , and the driving mechanism 500 is used to drive the air inlet panel 200 to move relative to the fan blade assembly 100 .

[0052] In some embodiments, the driving mechanism 500 can be connected to the corresponding control module for communication. When air intake or air intake volume adjustment is required, the driving mechanism 500 only needs to be controlled by the control module to drive the air intake panel 200 relative to the fan blade assembly 100. The control module can be a microcontroller or a single-chip microcomputer.

[0053] Specifically, the driving mechanism 500 may be a telescopic driving component 510, such as a driving cylinder or a telescopic rod.

[0054] Please refer to Figures 5 to 8 In some embodiments, the driving mechanism 500 includes a driving member 510 and a connecting rod 520, one end of the connecting rod 520 is rotatably connected to the driving member 510, and the other end of the connecting rod 520 is connected to the air inlet panel 200, and the connecting rod 520 and the air inlet panel 200 form a connecting rod 520 slider 600 mechanism. When in use, the driving member 510 drives the connecting rod 520 to rotate and the connecting rod 520 drives the air inlet panel 200 to move relative to the mounting base 110. In this way, when it is necessary to introduce wind or adjust the air intake volume, it is only necessary to drive the connecting rod 520 to rotate within a predetermined range through the driving member 510, and the adjustment reliability is relatively high.

[0055] Please refer to Figure 4 and Figure 5 In some embodiments, the driving member 510 includes a motor 512 and a crank bracket 514 connected to the motor 512, and the crank bracket 514 is rotatably connected to the connecting rod 520. In this way, the crank bracket 514, the connecting rod 520 and the air inlet panel 200 form a crank 5144 slider 600 mechanism. When in use, the air inlet panel 200 is controlled to move in a direction close to or away from the air inlet end 122 of the fan blade by the forward and reverse rotation of the motor 512.

[0056] Please refer to Figure 5 In some embodiments, the number of air inlet panels 200 is at least two, and at least two air inlet panels 200 are arranged along the circumference of the mounting base 110. The number of connecting rods 520 is at least two, and the crank bracket 514 includes a mounting body 5142 connected to the motor 512 and cranks 5144 arranged at intervals along the circumference of the mounting body 5142. One crank 5144 is rotatably connected to one connecting rod 520. In this way, when the motor 512 is in motion, at least two air inlet panels 200 can be driven to move simultaneously through the crank 5144 and the connecting rod 520.

[0057] Please refer to Figure 5 and Figure 7Taking four air inlet panels 200 as an example, in this embodiment, there are four cranks 5144, which are arranged on the mounting body 5142 at equal intervals along the circumference of the mounting body 5142, the mounting base 110 is a circular plate, the air inlet panels 200 are arc-shaped plates, and the four air inlet panels 200 are arranged along the circumference of the mounting base 110. Please refer to Figure 1 and Figure 5 When the four air inlet panels 200 are in contact with each other, they just surround and form a cylindrical installation space 700, the size of which matches the size of the fan assembly. Figure 2 and Figure 7 When the fan structure 10 is started, the motor 512 drives the four air inlet panels 200 to move in a direction away from the mounting base 110 at the same time, and the air inlet panels 200 and the fan blades 120 are spaced to form an air inlet 300. As the air inlet panels 200 continue to move away from the fan blades 120, the air inlet 300 also continues to increase, and the corresponding air intake volume also continues to increase. When the air intake volume needs to be reduced, it is only necessary to drive the motor 512 to reverse, and at this time, the air inlet panel 200 is driven to move in a direction close to the mounting base 110, and the air inlet 300 is reduced.

[0058] It should be noted that, when two adjacent air inlet panels 200 are moved to be spaced apart from each other, the gap 800 formed between the two adjacent air inlet panels 200 can also let in air.

[0059] In addition, the present application also relates to an air conditioning device, comprising the fan structure 10 in any of the aforementioned embodiments.

[0060] The above-mentioned air conditioning device includes the fan structure 10 in any of the above-mentioned embodiments. Therefore, when the air conditioning device is in use, the air inlet panel 200 can be driven to move in a direction away from the fan blade assembly 100 so that an air inlet 300 is formed between the air inlet end of the fan blade assembly 100 and the air inlet panel 200. At this time, the air inlet 300 enters the fan blade assembly 100 at the lower edge of the active air suction of the fan blade assembly 100. When the air intake volume needs to be adjusted, it is only necessary to adjust the air inlet panel 200 and the air inlet end of the fan blade assembly 100. The larger the distance between the air inlet panel 200 and the air inlet end of the fan blade assembly 100, the larger the air inlet area of ​​the air inlet 300 and the corresponding air intake volume; or when the air intake volume needs to be adjusted, it is only necessary to drive the air inlet panel 200 to move relative to the fan blade assembly 100 in the direction of expanding or reducing the air inlet 300; in this way, adjusting the air intake volume by adjusting the size of the air inlet area of ​​the air inlet 300 can avoid increasing the power consumption of the equipment and the noise of the equipment operation, and at the same time can avoid the shaking of the fuselage.

[0061] The air conditioning device in the aforementioned embodiment may be an air conditioner, an air purifier, a fan, or other device that can adjust the temperature or quality of the air.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.
