In order to achieve a better temperature adjusting effect, the existing ceiling has the problem that a guide vane structure is arranged at an air outlet to adjust the air outlet direction, but the effective control of the air outlet direction is difficult to achieve by the common guide vane structure, and the adjusting effect is poor.
In view of the above, the present invention provides a ceiling fan, and referring to fig. 1 to 5, fig. 1 to 5 are embodiments of the ceiling fan provided by the present invention.
As shown in fig. 1 to 5, the ceiling fan 100 includes a housing 1, an air inlet 11 and an air outlet 12 provided on the housing 1, and an air duct 13 provided in the housing 1 and communicating the air inlet 11 and the air outlet 12, and a negative pressure forming device 2 mounted on one side of the air outlet 12 to form a negative pressure region on one side of the air outlet 12.
According to the technical scheme, the negative pressure forming device 2 is arranged on one side of the air outlet 12, so that a negative pressure area is formed on one side of the air outlet 12, when the air outlet direction of the ceiling machine 100 needs to be regulated, the negative pressure area is formed on one side of the air outlet 12 by utilizing the negative pressure forming device 2, so that air exhausted from the air duct 13 through the air outlet 12 flows to the negative pressure area to deflect, the regulation of the air outlet direction is realized in a negative pressure suction mode, the air outlet direction can be effectively controlled, and the regulation effect is good; the shape of the air duct 13 is not required to be changed, and the attenuation of refrigerating and heating quantity and the increase of noise caused by the change of the shape of the air duct 13 are avoided.
Further, the negative pressure forming device 2 includes a movable member 21 and a driving device, the movable member 21 is disposed on the casing 1 and defines a cavity 14 with an opening 141 between the movable member and the casing 1, the opening 141 is disposed adjacent to the air outlet 12, and the driving device drives the movable member 21 to move so that the volume of the cavity 14 is periodically changed. When the air outlet direction of the ceiling fan 100 needs to be adjusted, the driving device is used for driving the movable piece 21 to reciprocate, so that the volume of the cavity 14 between the movable piece 21 and the machine shell 1 is periodically changed, and the cavity 14 periodically discharges and sucks air through the opening 141, thereby forming a negative pressure area at one side of the air outlet 12, and further deflecting the air discharged from the air duct 13 through the air outlet 12 to the negative pressure area, so as to realize the adjustment of the air outlet direction of the ceiling fan 100; the movable member 21 replaces the conventional guide vane structure with complex structure, and the structure of the ceiling fan 100 is simplified.
The casing 1 includes a housing 15 and a panel 16 covering a lower end of the housing 15, the panel 16 forming a bottom of the casing 1, and a side of the housing 15 and a side of the panel 16 forming a side of the casing 1. The housing 15 may be integrally provided with the panel 16 or may be separately provided. Of course, the ceiling fan 100 further includes a fan 3 and a heat exchanger 4 disposed in the housing 1, the fan 3 is configured to suck and send indoor air, and the heat exchanger 4 is configured to cool and heat the sucked air.
It should be noted that, the specific position of the air outlet 12 on the casing 1 is not limited in the present invention, and the air outlet 12 may be disposed at a side portion of the casing 1, or the air outlet 12 may be disposed at a bottom portion of the casing 1. When the air outlet 12 is arranged at the side part of the casing 1, the air flow discharged from the air duct 13 through the air outlet 12 can be deflected downwards or upwards to adjust the air outlet direction; when the air outlet 12 is disposed at the bottom of the casing 1, the air discharged from the air duct 13 through the air outlet 12 may be turned to flow to the Zhou Cepian of the air outlet 12 to adjust the air outlet direction.
For the case that the air outlet 12 is disposed at the side of the casing 1, referring to fig. 2, the air outlet 12 is disposed at the side of the casing 1 and at a lower position; the opening 141 is located below the air outlet 12. At this time, the cavity 14 is defined between the movable member 21 and the bottom of the casing 1, and when the volume of the cavity 14 changes periodically, a negative pressure area is generated at the lower side of the air outlet 12, so as to generate an effect of deflecting downward the air flow discharged from the air duct 13 through the air outlet 12; because the air outlet 12 is located at the side of the casing 1 and at a lower position, when the ceiling fan 100 is mounted on the ceiling, the air outlet 12 is far away from the ceiling, and the air outlet 12 is not easy to be blocked by the ceiling, so that the air outlet is facilitated; if the air outlet 12 is disposed at the side of the casing 1, and the movable member 21 is also disposed at the side of the casing 1, and the side of the ceiling machine 100 is generally a cylindrical wall or a square cylindrical wall, this may result in an increase in the structural complexity of the movable member 21 and difficulty in installation, and in this embodiment, the movable member 21 is not disposed at the side of the casing 1 as the air outlet 12, but at the bottom of the casing 1, which is beneficial to simplifying the structure of the movable member 21 and having the advantage of convenient installation.
Further, the movable member 21 has an outer edge 211 adjacent to the air outlet 12, the opening 141 is defined between the outer edge 211 of the movable member 21 and the housing 1, and a maximum distance between the outer edge 211 of the movable member 21 and a center line of the housing 1 is greater than a maximum distance between the air outlet 12 and the center line of the housing 1. Specifically, referring to fig. 3, the maximum distance between the outer edge 211 of the movable member 21 and the center line of the housing 1 is L 1 The maximum distance between the air outlet 12 and the center line of the casing 1 is L 2 ，L 1 And L is equal to 2 The relationship between is fullFoot L 1 >L 2 . Provided L 1 ≤L 2 That is, the outer edge 211 of the movable member 21 does not exceed the air outlet 12, and the movable member 21 is completely located under the bottom of the casing 1, so that the suction force of the negative pressure area on the air flow is interfered by the side of the casing 1. In the scheme, through L 1 >L 2 The air flow discharged from the air duct 13 through the air outlet 12 is more easily deflected downwards by the suction force of the negative pressure area, and the effect of adjusting the air outlet direction is better.
The location of the air inlet 11 on the housing 1 may be varied, for example, the air inlet 11 is disposed on a side of the housing 1, and the air inlet 11 is disposed on a bottom of the housing 1. In the embodiment of the present invention, the movable member 21 is disposed at the bottom of the housing 1, and the air inlet 11 is disposed at the bottom of the housing 1 and penetrates through the movable member 21. The shape of the air inlet 11 may be various, for example, circular, elliptical or square, and is not particularly limited herein. Furthermore, in some embodiments, an air inlet grille may be mounted on the air inlet 11, and the air inlet grille is passed by indoor air to enable the indoor air to enter the casing 1, so as to better regulate the air inlet quantity.
Further, an air guiding portion 211a is provided at the outer edge 211 of the movable member 21, and the air guiding portion 211a extends downward in a direction away from the center line of the housing 1. Since the air guiding portion 211a extends downward in a direction away from the center line of the casing 1, after the air flow discharged from the air duct 13 through the air outlet 12 is sucked and deflected downward by the negative pressure region, the air flow will flow downward in a direction toward the outside of the casing 1 against a side surface of the air guiding portion 211a adjacent to the air outlet 12, thereby forming an air guiding effect, and being more beneficial to the deflection of the air flow.
In addition, a side surface of the air guiding portion 211a adjacent to the air outlet 12 is provided with an arc surface. In this way, the wind guiding function of the wind guiding portion 211a is further increased, and the airflow deflection effect is improved. Further, a side surface of the air guiding portion 211a adjacent to the air outlet 12 is provided with an arc surface protruding outwards towards the air outlet 12, which is helpful to increase the downward deflection degree.
It should be noted that, a side of the air guiding portion 211a adjacent to the air outlet 12 is a smooth surface, and the roughness is not limited, so as not to obstruct the airflow.
Further, the movable member 21 is provided in a horn shape expanding downward. In this way, the peripheral wall of the movable member 21 forms the annular air guiding portion 211a, the air guiding area is larger, the air guiding effect is better, and the air outlet direction is more effectively adjusted.
The shape of the air outlet 12 may be varied, such as circular, oval, square or polygonal, and the like, and is not particularly limited herein. The air outlet 12 is annular and is arranged at the side part of the casing 1. In this way, the circumferential 360-degree annular air outlet of the ceiling fan 100 is realized, and in general, compared with the non-annular air outlet 12, the guide vane structure required by the annular air outlet 12 for adjusting the air outlet direction is more complex, but the movable piece 21 is also suitable for the annular air outlet 12, and the air outlet direction of the annular air outlet 12 is effectively adjusted while the guide vane structure is not needed.
In the case that the air outlet 12 is disposed at the bottom of the casing 1, specifically, the air outlet 12 is disposed at the bottom of the casing 1; the movable member 21 is disposed in a ring shape, and is disposed around the periphery of the air outlet 12 (not shown in the drawings). With this arrangement, the ceiling machine 100 can be fully embedded within the ceiling when mounted thereto, helping to conserve indoor space.
The shape of the casing 1 may be various, such as a rectangular parallelepiped, a cylindrical body, etc., and is not particularly limited herein. The casing 1 includes a housing 15 and a panel 16 covering a lower end of the housing 15, the panel 16 forming a bottom of the casing 1, and a side of the housing 15 and a side of the panel 16 forming a side of the casing 1. The housing 15 may be integrally provided with the panel 16 or may be separately provided. When the shell 15 and the panel 16 are separately arranged, the shell 15 and the panel 16 are detachably connected, the connection position of the shell 15 and the panel 16 is close to the middle part of the panel 16, namely, far away from the periphery of the panel 16, so that when the panel 16 is acted by self weight, the gravity of the panel 16 can be well counteracted at the connection position of the panel 16 and the shell 15, thereby the connection between the shell 15 and the panel 16 is more stable, the stability of the panel 16 after installation is improved, and the leakage of air flow in the air duct 13 from between the shell 15 and the panel 16 is avoided. Of course, the ceiling fan 100 further includes a fan 3 and a heat exchanger 4 disposed in the housing 1, the fan 3 is configured to suck and send indoor air, and the heat exchanger 4 is configured to cool and heat the sucked air.
The driving means for driving the movable member 21 may be a swing driving means or a linear driving means. The driving device is a swing driving device, and the swing driving device drives the movable piece 21 to swing reciprocally in the direction approaching and separating from the casing 1, so that the volume of a cavity between the movable piece 21 and the casing 1 is periodically changed, a negative pressure area is formed, and the air flow discharged from the air duct 13 through the air outlet 12 is attracted to deflect, so that the air outlet direction is adjusted.
The driving means includes linear driving means that drives the movable member 21 to move in a direction approaching and moving away from the casing 1. The movable piece 21 is driven by the linear driving device to linearly reciprocate in the direction approaching to and separating from the casing 1, so that the cavity volume between the movable piece 21 and the casing 1 is changed, and a negative pressure area is formed at one side of the air outlet 12, so that the air flow discharged from the air duct 13 through the air outlet 12 is attracted to deflect, and the air outlet direction is regulated. Compared with a swing driving device, the movable reserved space of the movable piece 21 required by the driving mode of the linear driving device is smaller, so that the waste of the space of the machine body is avoided, and the machine body is miniaturized.
Further, the linear driving device includes a magnetic circuit structure mounted to the casing 1, the magnetic circuit structure being formed with a magnetic field, and a driving coil (not shown in the drawings) disposed in the magnetic field of the magnetic circuit structure and driven by the magnetic field to move along a straight line in the case of applying alternating current, and the movable member 21 is connected to the driving coil to be driven by the driving coil to move in a direction approaching and separating from the casing 1. That is, the movable member 21 is driven to linearly move in a direction approaching and separating from the casing 1 in an electromagnetic driving manner, so that the control is easy; and no additional transmission mechanisms such as gear transmission and the like are needed, so that noise caused by the transmission mechanisms is avoided; the linear driving device has a simple structure, is matched with the movable piece 21 with a simple structure, can realize the control of the movable piece 21 with small energy, and consumes less electric energy; the linear motion of the driving coil is used to drive the movable member 21, the frequency and amplitude of which can be controlled well, and noise caused by the driving coil can be eliminated more easily than that caused by a conventional driving device.
Further, the air duct 13 includes an air outlet section 131 connected to the air outlet 12, and the air outlet section 131 is gradually expanded in a direction toward the air outlet 12. Specifically, referring to fig. 4 and 5, an included angle D exists between a bus bar of the side wall of the air outlet section 131 and the center line of the air outlet 12. In this way, the air flow discharged from the air duct 13 through the air outlet 12 has a slight expansion from the outside, and after a negative pressure area is formed on one side of the air outlet 12, the main flow of the air flow discharged from the air duct 13 through the air outlet 12 can deflect a larger angle, so that the air flow deflection effect is better. For example, the direction of the center line of the air outlet section 131 is taken as the horizontal direction, and after the air outlet section 131 is taken as the horizontal direction, the air flow is discharged from the air duct 13 through the air outlet 12, the main flow direction of the air flow is also the horizontal direction, the outside of the air flow has slight upward and downward expansion, after a negative pressure area is formed on one side of the air outlet 12, the main flow of the air flow is easier to deflect upward or downward from the horizontal direction on the basis of slight expansion, and the air flow deflection effect is better.
In order to prevent the expansion angle of the air flow discharged from the air duct 13 through the air outlet 12 from being excessively large, it is preferable that the included angle D between the bus bar of the side wall of the air outlet section 131 and the center line of the air outlet 12 is 0 to 45 degrees, as shown in fig. 5.
The present invention does not limit the specific central line direction of the air outlet section 131. When the air outlet 12 is disposed at the side of the casing 1, the direction of the central line of the air outlet section 131 may be a horizontal direction or a direction forming a certain angle with the horizontal direction. For example, the central line direction of the air outlet section 131 is a horizontal direction, the movable member 21 is disposed at the lower side of the air outlet 12, and the negative pressure area formed by the movable member 21 changes the air flow from the horizontal direction to a direction inclined downward in the horizontal direction, that is, the air outlet of the ceiling fan 100 has two modes, the movable member 21 is not opened, the air outlet is horizontal, the movable member 21 is opened, and the air outlet is inclined downward. For another example, the central line direction of the air outlet section 131 is a horizontal direction, the movable member 21 is disposed on the upper side of the air outlet 12, and the negative pressure area formed by the movable member 21 changes the air flow from the horizontal direction to a direction inclined upwards in the horizontal direction, that is, the air outlet of the ceiling fan 100 has two modes, the movable member 21 is not opened, the air is horizontally discharged, the movable member 21 is opened, and the air is discharged obliquely upwards. For another example, the direction of the center line of the air outlet section 131 is a direction inclined downward in the horizontal direction, the movable member 21 is disposed on the upper side of the air outlet 12, and the negative pressure area formed by the movable member 21 changes the air flow from the direction inclined downward in the horizontal direction to the horizontal direction, that is, the air outlet of the ceiling fan 100 has two modes, the movable member 21 is not opened, the air outlet is inclined downward, and the movable member 21 is opened to discharge air horizontally. When the air outlet 12 is disposed at the bottom of the casing 1, the direction of the central line of the air outlet section 131 may be a vertical direction or a direction having a certain included angle with the vertical direction.
The air duct 13 further includes a main air section 132 (refer to fig. 4 herein) connected to an end of the air outlet section 131 facing away from the air outlet 12, and the main air section extends vertically. The downward main air section 132 is beneficial to guiding the air which enters from the air inlet and is cooled or heated in the casing 1 to the air outlet section 131, so as to improve the air outlet effect of the ceiling fan 100.
The upper and lower side walls of the air outlet section 131 are symmetrically arranged. When the air flow discharged from the air duct 13 through the air outlet 12 is just discharged, although the outside of the air flow has slight expansion, the main flow direction of the air flow is kept consistent with the direction of the air duct 13, and the main flow direction of the air flow is deflected only after a negative pressure area is formed on one side of the air outlet 12, so that the air outlet direction is regulated more effectively. For example, when the central line direction of the air outlet section 131 is a horizontal direction, the symmetrical arrangement between the upper and lower sidewalls of the air outlet section 131 ensures that the main flow direction of the air flow is a horizontal direction.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the specification and drawings of the present invention or direct/indirect application in other related technical fields are included in the scope of the present invention.
