Description

[Technical Field]

[0001] This invention relates to the field of fan technology, and in particular to a bladeless ceiling fan with an adjustable airflow range. [Background Technology]

[0002] Traditional ceiling fans are typically fixed to the ceiling. Because the ceiling fan is permanently connected to the ceiling, the distance between the fan and the floor is also fixed, resulting in a relatively fixed airflow range. This limits the range of airflow, making it difficult to adjust according to user needs and meet diverse requirements.

[0003] Therefore, this invention addresses the aforementioned problems. [Summary of the Invention]

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bladeless ceiling fan with an adjustable airflow range. The airflow range is adjusted by controlling the lifting and lowering of the mounting shell relative to the mounting base through a lifting and adjusting mechanism. This allows the airflow range of the bladeless ceiling fan to be adjusted according to usage needs or usage scenarios, and it has the characteristics of high practicality and strong adaptability.

[0005] This invention is achieved through the following technical solution:

[0006] A bladeless ceiling fan with adjustable airflow range includes a mounting base 1 and a mounting housing 2 connected to the mounting base 1. The mounting housing 2 is provided with an air inlet 21 and an air outlet 23. An installation space 22 is provided on the mounting housing 2 between the air inlet 21 and the air outlet 23, and the installation space 22 connects the air inlet 21 and the air outlet 23. A fan 221 is provided in the installation space 22. An air outlet 24 with an inclined angle is provided on the mounting housing 2 along the circumference of the bottom of the mounting housing 2, and the air outlet 24 is connected to the air outlet 23.

[0007] A lifting adjustment mechanism 3 is provided between the mounting housing 2 and the mounting base 1, which enables the mounting housing 2 to be raised and lowered relative to the mounting base 1 to adjust the air blowing range.

[0008] As described above, in a bladeless ceiling fan with an adjustable airflow range, the air outlet 24 has an outward tilt angle.

[0009] As described above, in a bladeless ceiling fan with adjustable airflow range, a wind direction adjustment component for adjusting the airflow direction is provided on the mounting housing 2 and located at the air outlet 24.

[0010] As described above, in a bladeless ceiling fan with adjustable airflow range, a filter assembly 222 is provided within the installation space 22 and located between the air inlet 21 and the fan 221.

[0011] As described above, in a bladeless ceiling fan with adjustable airflow range, the fan 221 is a centrifugal fan.

[0012] As described above, in a bladeless ceiling fan with adjustable airflow range, the lifting adjustment mechanism 3 includes a lifting motor 31 mounted on a mounting base 1. The motor shaft of the lifting motor 31 is movably connected to a lifting screw 32. The lifting screw 32 is provided with a lifting nut 33 that can slide along its length. The lifting nut 33 is fixedly connected to the mounting housing 2.

[0013] As described above, in a bladeless ceiling fan with adjustable airflow range, the cross-sections of the connecting ends of the mounting base 1 and the mounting housing 2 are both cylindrical. An anti-rotation component 4 is provided between the connecting end of the mounting base 1 and the connecting end of the mounting housing 2. The anti-rotation component 4 includes an anti-rotation groove 41 provided on the inner wall of the connecting end of the mounting base 1 and an anti-rotation protrusion 42 provided on the outer wall of the connecting end of the mounting housing 2 and cooperating with the anti-rotation groove 41.

[0014] As described above, in a bladeless ceiling fan with adjustable airflow range, the bottom surface of the mounting housing 2 is provided with a lighting component 5.

[0015] The present invention also provides a method for operating a bladeless ceiling fan with adjustable airflow range, using the bladeless ceiling fan with adjustable airflow range as described above, the method comprising the following steps:

[0016] S1. First calculate the height H between the air outlet 24 and the plane where the required air blowing range is located. Based on the radius R of the plane where the required air blowing range is located and the angle α between the air outlet 24 and the horizontal plane, we have H=R×tanα.

[0017] S2, compare the actual height between the air outlet 24 and the plane where the required air blowing range is located, which is H1. When H1 > H, the radius of the plane where the air blowing range is located is R1. Then R1 > R. The lifting adjustment mechanism 3 controls the mounting housing 2 to descend relative to the mounting base 1 until H1 = H, and then R1 = R.

[0018] When H1 < H, then R1 < R. The lifting and adjusting mechanism 3 controls the mounting housing 2 to rise relative to the mounting base 1 until H1 = H, and then R1 = R.

[0019] As described above, in the operation method of a bladeless ceiling fan with adjustable airflow range, a wind direction adjustment component for adjusting the airflow direction is provided on the mounting housing 2 and located at the air outlet 24.

[0020] When H1 > H, then R1 > R. If the lifting adjustment mechanism 3 controls the installation housing 2 to descend relative to the installation base 1 but cannot make H1 = H, the air direction adjustment component is used to adjust the air outlet 24 to make R1 = R.

[0021] When H1 < H, then R1 < R. If the lifting adjustment mechanism 3 controls the installation housing 2 to rise relative to the installation base 1 but fails to make H1 = H, the air direction adjustment component is used to adjust the air outlet 24 to make R1 = R.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. When using this invention, the lifting and adjusting mechanism controls the lifting and adjusting of the mounting housing relative to the mounting base to adjust the air blowing range. This allows the air blowing range of the bladeless ceiling fan to be adjusted according to usage needs or usage scenarios, making it highly practical and adaptable.

[0024] 2. In this invention, the wind direction adjustment component and the lifting adjustment mechanism work together to make the airflow range of the bladeless ceiling fan more flexible and convenient to adjust.

[0025] 3. This invention provides a filter component between the air inlet and the fan, which can protect the fan to a certain extent and prevent external dust and flying insects from entering the installation space and affecting the normal operation of the fan. [Attached Image Description]

Detailed Implementation Methods

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] like Figure 1-9 As shown, the present invention discloses a bladeless ceiling fan with adjustable airflow range, comprising a mounting base 1 and a mounting housing 2 connected to the mounting base 1. The mounting housing 2 is provided with an air inlet 21 and an air outlet 23. An installation space 22 is provided on the mounting housing 2 between the air inlet 21 and the air outlet 23, and the installation space 22 connects the air inlet 21 and the air outlet 23. A fan 221 is provided in the installation space 22. An air outlet 24 with an inclined angle is provided on the mounting housing 2 along the circumferential direction of the bottom of the mounting housing 2, and the air outlet 24 is connected to the air outlet 23.

[0038] A lifting and adjusting mechanism 3 is provided between the mounting housing 2 and the mounting base 1, which allows the mounting housing 2 to be raised and lowered relative to the mounting base 1 to adjust the airflow range. When in use, the lifting and adjusting mechanism controls the raising and lowering of the mounting housing relative to the mounting base to adjust the airflow range, thus allowing the airflow range of the bladeless ceiling fan to be adjusted according to usage needs or scenarios, exhibiting high practicality and adaptability.

[0039] When a bladeless ceiling fan is installed on the ceiling of a dining room, the lifting and adjustment mechanism controls the lifting and adjustment of the mounting shell relative to the mounting base so that the airflow range of the bladeless ceiling fan is outside the edge of the dining table, thus preventing the bladeless ceiling fan from blowing air onto the dining table.

[0040] like Figure 5 , 6 As shown, the air outlet 24 has an outward tilt angle, which allows the air blown out of the air outlet 24 to blow outwards towards the outside of the bladeless ceiling fan, thus making the air blowing range wider.

[0041] The mounting housing 2 is equipped with an air direction adjustment component for adjusting the airflow direction at the air outlet 24, which is not shown in the figure. In this embodiment, the air direction adjustment component and the lifting adjustment mechanism work together to more flexibly and conveniently adjust the airflow range of the bladeless ceiling fan.

[0042] To better adjust the airflow direction, the airflow adjustment component includes a guide plate rotatably disposed at the air outlet 24 and a drive motor disposed on the mounting housing 2 for driving the guide plate to rotate, thereby adjusting the airflow direction.

[0043] The structure of the wind direction adjustment component can also be found in application documents such as CN201810512601.9 and CN201911129741.9.

[0044] like Figure 3-6 As shown, a filter assembly 222 is provided in the installation space 22 and between the air inlet 21 and the fan 221. It can protect the fan to a certain extent, prevent external dust and flying insects from entering the installation space and affecting the normal operation of the fan, and also purify the air, preventing dust and other foreign objects from being blown into the food.

[0045] Preferably, the fan 221 is a centrifugal fan, which can improve the ventilation efficiency of the bladeless ceiling fan, thereby improving the blowing efficiency. At the same time, the use of a centrifugal fan also has the characteristics of stable operation and long service life.

[0046] like Figure 3-6 As shown, to improve the lifting efficiency of the mounting housing and thus change the airflow range of the bladeless ceiling fan, the lifting adjustment mechanism 3 includes a lifting motor 31 mounted on the mounting base 1. The motor shaft of the lifting motor 31 is movably connected to a lifting screw 32. The lifting screw 32 is equipped with a lifting nut 33 that slides along its length. The lifting nut 33 is fixedly connected to the mounting housing 2. When it is necessary to adjust the mounting housing to descend, the lifting motor 31 drives the lifting screw 32 to rotate forward, causing the lifting nut 33 to slide downwards along the length of the lifting screw 32, thereby lowering the mounting housing. When it is necessary to adjust the mounting housing to rise, the working principle is simply the reverse of the working principle when the mounting housing is descending.

[0047] like Figure 3 , 4 As shown, in order to ensure that the mounting housing moves stably and smoothly relative to the mounting base, the cross-section of the connecting end of the mounting base 1 and the mounting housing 2 is cylindrical. An anti-rotation component 4 is provided between the connecting end of the mounting base 1 and the connecting end of the mounting housing 2. The anti-rotation component 4 includes an anti-rotation groove 41 provided on the inner wall of the connecting end of the mounting base 1 and an anti-rotation protrusion 42 provided on the outer wall of the connecting end of the mounting housing 2 and cooperating with the anti-rotation groove 41.

[0048] like Figure 3 , 5 As shown in Figure 6, in order to enable the bladeless ceiling fan to have a lighting function and improve its practicality, a lighting component 5 is provided on the bottom surface of the mounting housing 2. The lighting component 5 can be an LED light bead, etc.

[0049] like Figure 1-9 As shown, the present invention discloses a method for operating a bladeless ceiling fan with adjustable airflow range. The method employs a bladeless ceiling fan with adjustable airflow range as described above, and includes the following steps:

[0050] S1. First calculate the height H between the air outlet 24 and the plane where the required air blowing range is located. Based on the radius R of the plane where the required air blowing range is located and the angle α between the air outlet 24 and the horizontal plane, we have H=R×tanα.

[0051] S2, compare the actual height between the air outlet 24 and the plane where the required air blowing range is located, which is H1. When H1 > H, the radius of the plane where the air blowing range is located is R1. Then R1 > R. The lifting adjustment mechanism 3 controls the mounting housing 2 to descend relative to the mounting base 1 until H1 = H, and then R1 = R.

[0052] When H1 < H, then R1 < R. The lifting and adjusting mechanism 3 controls the mounting housing 2 to rise relative to the mounting base 1 until H1 = H, and thus R1 = R. The working method of this invention adopts the above-mentioned bladeless ceiling fan structure. Therefore, this working method can adjust the airflow range of the bladeless ceiling fan according to the usage requirements or usage scenarios, and has the characteristics of strong adaptability.

[0053] In order to more flexibly adjust the airflow range of the bladeless ceiling fan, an airflow adjustment component for adjusting the airflow direction is provided on the mounting housing 2 and located at the air outlet 24.

[0054] When H1 > H, then R1 > R. If the lifting adjustment mechanism 3 controls the installation housing 2 to descend relative to the installation base 1 but cannot make H1 = H, the air direction adjustment component is used to adjust the air outlet 24 to make R1 = R.

[0055] When H1 < H, then R1 < R. If the lifting adjustment mechanism 3 controls the installation housing 2 to rise relative to the installation base 1 but fails to make H1 = H, the air direction adjustment component is used to adjust the air outlet 24 to make R1 = R.
