Description

Technical Field

[0001] The present invention relates to the field of air conditioning, in particular to a fan and a filter replacement method thereof. Background Art

[0002] Most of the existing bladeless fans are low-intake and upward-blowing models. Air is sucked in from the bottom through the vertical motor at the bottom of the bladeless fan, and a vertical air flow is generated by the vertical motor. After being transported to the nozzle above the vertical motor, the air flow is guided to the horizontal direction and ejected by the nozzle.

[0003] This structure has the following technical problems:

[0004] 1. The air intake position is low, which easily sucks in dust from the ground or table, thereby reducing the air quality and shortening the service life of the air purifier in the fan.

[0005] 2. The filter of a traditional bladeless fan is set at the bottom. Taking the use scenario of the fan on the ground as an example, every time the filter is replaced, the user needs to disassemble the shell and bend down to take out the old filter, and then bend down again to replace the new filter. The user experience is not good, especially for the elderly. There are hidden dangers in use when replacing the filter.

[0006] 3. In order to achieve the effect of high-altitude air discharge, existing products simply increase the height of the nozzle. However, the farther the vertical distance the vertical motor at the bottom transports the air flow, the smaller the wind force, resulting in a large amount of air at the bottom of the nozzle and a small amount of air at the top. This is completely contrary to the purpose of the vertical fan, which is mainly to supply air to the upper body of the human body. Therefore, traditional bladeless fans and related improved products cannot replace the effect of vertical fans.

[0007] Therefore, the present invention provides a fan. Summary of the Invention

[0008] In response to the problems in the prior art, the purpose of the present invention is to provide a fan that overcomes the problems of the prior art, can raise the position of air intake to prevent indoor surface air from entering the fan, and can concentrate wind power to emit at a high position, completely replacing the traditional vertical fan, expanding the usage scenarios and improving the user experience.

[0053] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures represent identical or similar structures, and thus a repeated description thereof will be omitted.

[0054] Figure 1 This is a three-dimensional diagram of the fan of the present invention from a first viewing angle. Figure 2 This is a perspective view of the fan of the present invention from a second viewing angle. Figure 3 FIG. 1 is a side cross-sectional view of the fan of the present invention. Figures 1 to 3 As shown, the fan of the present invention includes: an integral body 1, a support member 41, a base 42 and a nozzle 7. The body 1 includes an air inlet, an air outlet and a fan motor assembly 5. The fan motor assembly 5 includes a horizontal motor for generating an air flow through the body 1. The support member 41 supports the body 1. The nozzle 7 is connected to the body 1 based on the air outlet direction of the horizontal motor, and is used to receive the air flow from the body, spread it to each air outlet 71 along the inside of the nozzle 7 and spray it. The base 42 supports the support member 41. The support member 41 is a support rod, and the extension direction of the support rod is perpendicular to the rotation axis of the horizontal motor. The opening direction of the air outlet 71 is parallel to the rotation axis of the horizontal motor. The outer shell of the body 1 is a horizontally arranged cylindrical shell, which is sleeved with the horizontal motor, and the shell is provided with a plurality of air inlet holes 11. The cylindrical housing includes opposing first and second ends. The first end of the cylindrical housing is connected to an air guide 6, which guides the air flow to the bottom 7A of the nozzle 7. The air flow moves along the internal annular air duct of the annular nozzle in the direction of gravity toward the top 7B of the nozzle 7, and is sequentially distributed to each air outlet 71 before being emitted separately. The second end of the cylindrical housing is provided with a removable cover. The present invention provides a bladeless fan primarily for use in vertical fan scenarios, completely replacing traditional vertical fans, expanding usage scenarios, and improving user experience.

[0055] In a preferred embodiment, the support rod is a liftable support tube assembly, which includes an inner tube and an outer tube that are axially movable and position-limited relative to each other, so that the vertical height of the fan air outlet can be freely adjusted.

[0056] Figure 4 This is a schematic diagram of the direction of movement of the air flow of the fan of the present invention in the air guide cover and the nozzle. Figure 3 and 4 As shown, nozzle 7 is a hollow annular nozzle with a plurality of air outlets 71 distributed along the extension direction of the inner cavity of the annular nozzle on the side of the annular nozzle facing away from the body 1. In a preferred embodiment, the internal pipeline of nozzle 7 gradually decreases in flow cross-sectional area as the position of nozzle 7 changes from bottom 7A to top 7B, thereby achieving a remote pressure boosting effect, but the present invention is not limited to this.

[0057] The air guide 6 in this embodiment includes at least a first guide slope 61, an air separation wall 62, a second guide slope 63, and a third guide slope 64. The first guide slope 61 is a sloped surface that deflects the air flow generated by the fan motor assembly 5 downward by 70° to 85° from the horizontal direction (preferably, deflecting the air flow downward by 80° from the horizontal direction). The air outlet direction of the horizontal motor is perpendicular to the direction of movement of the air flow in the inner cavity of the nozzle 7, but the present invention is not limited to this.

[0058] The air-dividing wall 62 is embedded in the range of the internal pipeline of the nozzle 7 and is connected after the first drainage slope 61. The air-dividing wall 62 is configured to be set vertically, and the left and right sides of the air-dividing wall 62 respectively form an arc-shaped second drainage slope 63 and a third drainage slope 64, which extend in an arc shape to the left and right sides. The air-dividing wall 62 divides the air flow introduced into the first drainage slope 61 into a first air branch and a second air branch. Among them, the first air branch enters the internal pipeline on the left side of the nozzle 7 to the left, moves in a clockwise direction toward the top 7B of the nozzle 7 (clockwise upward) to reach the various air outlets 71 on the left side of the nozzle 7, and is then ejected; similarly, the second air branch enters the internal pipeline on the right side of the nozzle 7 to the right, moves in a counterclockwise direction toward the top 7B of the nozzle 7 (counterclockwise upward) to reach the various air outlets 71 on the right side of the nozzle 7, and is then ejected, but is not limited to this.

[0059] In this embodiment, the first diversion slope 61, the air diversion wall 62, the second diversion slope 63, and the third diversion slope 64 are implemented by the surfaces of different parts of the same diversion structure, but the present invention is not limited to this. The present invention achieves the goal of diverting the linear air flow through the air guide 6 and the nozzle 7, and then smoothly guides it to the air outlets 71 of different nozzles 7, thereby reducing noise, avoiding the reduction of wind pressure when the air flow direction is adjusted, and maintaining the air flow volume. The air flow volume emitted by the nozzle 71 is basically close to the air flow volume generated by the fan motor assembly 5, and the wind loss caused by the internal pipeline is minimized.

[0060] Figure 5 FIG. 1 is a schematic diagram of the air outlet distribution of the nozzle of the fan of the present invention. Figure 5 As shown, the cross-sectional area of ​​each air outlet 71 gradually increases as the nozzle 7 moves from its bottom 7A to its top 7B. In this embodiment, by optimizing the opening area of ​​the air outlets at different locations, the air volume of each air outlet 71 at different heights is substantially equal, but this is not limiting. The air outlet 71 may also be circular, elliptical, or other shapes, without limitation.

[0061] In a preferred embodiment, the air outlet 71 is a rectangular opening, and as the air outlet 71 rises from the bottom 7A to the top 7B of the nozzle 7 based on the position of the nozzle 7, the length of the long side of the rectangular opening gradually increases, but the present invention is not limited thereto.

[0062] In a preferred embodiment, the air outlet 71 is a rectangular opening, and as the air outlet 71 rises from the bottom 7A to the top 7B of the nozzle 7 based on the position of the nozzle 7, the length of the short side of the rectangular opening gradually increases, but the present invention is not limited thereto.

[0063] Figure 6 Schematic diagram of replacing the filter of the fan of the present invention. Figure 6 As shown, the body 1 is further provided with an air intake hood 3 connected to the fan motor assembly 5. The annular gap between the air intake hood 3 and the outer shell is filled with a tubular filter 2, and the air intake hole 11 is located upstream of the tubular filter 2, which is located upstream of the air intake hood 3. The second end of the cylindrical shell is provided with a removable cover 12, which exposes the replaceable filter 2 after the cover 12 is removed. In this embodiment, the filter 2 is a tubular filter. The body 1 is further provided with an air intake hood 3 connected to the fan motor assembly 5. The annular gap between the air intake hood 3 and the outer shell forms an annular channel for inserting the tubular filter, and the central axis of the annular channel is parallel to the rotation axis of the horizontal motor. The annular channel is filled with the tubular filter 2, and the air intake hole 11 is located upstream of the tubular filter 2, which is located upstream of the air intake hood 3.

[0064] And, continue to refer to Figure 6 The present invention can replace the fan internal filter 2 through the following steps:

[0065] S110, removing the cover plate at the second end of the cylindrical housing to expose the filter to be replaced;

[0066] S120, pulling out the filter to be replaced in a direction parallel to the rotation axis of the horizontal motor;

[0067] S130, inserting another filter parallel to the rotation axis of the horizontal motor; and

[0068] S140, installing the cover back onto the second end of the cylindrical housing.

[0069] The filter in the present invention is located in the upper area of ​​the entire machine, and the user can replace the filter in an upright state without bending over, which reduces the user's physical effort and greatly optimizes the process of replacing the filter.

[0070] In summary, the purpose of the present invention is to provide a fan and a filter replacement method thereof, which can raise the position of air intake to prevent indoor surface air from entering the fan, and can concentrate wind power to be emitted at a high position, completely replacing the traditional vertical fan, expanding the usage scenarios and improving the user experience.

[0071] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered to fall within the scope of protection of the present invention.
