The present invention relates to electrical appliance, and more particular to an air circulation and guiding device for promoting and facilitating air flow within a predetermined airspace.
Interior space is a relatively closed space that the air within the interior space may not have the same flowing and smooth feeling as the outdoor air circulation. With the further understanding of air pollution and the need of respiratory health, great attention is paid to the indoor air circulation system. Many buildings are now equipped with central ventilation systems and many family houses are provided with air purifiers or circulation fans.
However, conventional air circulation devices have some disadvantages. For example, conventional central ventilation system is difficult to build into an existing building because substantial modification is required to structure of the building and the cost thereof is relatively high. In addition, most of the old buildings are not suitable for remodeling. For another example, the conventional air purifier or circulation fan is in a larger overall size, especially the conventional air purifier with high purification efficiency, which not only has high complexity in purifying mechanism, but also increases the maintenance cost of the multi-layer filter.
The most important consideration for indoor air circulation is to increase the air flowing capability and the indoor air quality will be much improved if specific filtration or purification is equipped. However, many conventional air circulation devices are designed to merely provide one of the two functions, either filtration or circulation. An air circulation fan and an air purifier are independently made to work together. Furthermore, in order to enhance the purification efficiency of the conventional air purifier, one of the improvement methods is to enhance and complicate the filtration process, but it directly reduces the air mobility. Conventional air purifier has a linear filtration path with one way direction to filtrate the air flowing therethrough, wherein although the linear flowing path increases the purification efficiency via the complicated filtration procedures, the filtration range and area is limited that only a specific and limited range of air is filtered repeatedly. In other words, it fails to increase the air mobility while the cost of the equipment is increased. When the filtering range of indoor space is limited by the air circulation, it is meaningless to the decontaminate work of a room while it merely filter a limited region in that room.
Another disadvantage is that the conventional air circulation device is generally designed with high power in order to achieve circulation coverage in a large area region. If the indoor space is relatively large, the mobility in the entire space is difficult to be covered with a single air filter device, and it is also harder to filter the entire space merely relying on a single air filter device. Accordingly, a plurality of devices is required for air circulation and air filtration or a large space is preferred to be divided into various air circulation and/or air filtration regions. The conventional air circulation device looks pretty bulky and is a source of noise and vibration at home. Also, due to the larger space to be occupied by the convention air circulation device, it is not easy to reduce costs and difficult to enhance its mobility and flexibility.
In fact, the one who needs better air circulation and quality is the user himself or herself. Therefore, an air circulator in compact and portable size that the user may carry or place near the user is the real need to the user. It is especially a good idea for the user to improve the air circulation and quality in his or her office or working environment with his or her own air circulator placed around.
The conventional air circulation device contains parts and components for controlling the air flow which are heavy and large in size that causes much inconvenience to the device. When air purification is required, the relative position and arrangement of the filter is really important that the interference between the circulation and filtration must be avoided. It is even better to have a design facilitating the air circulation. In other words, both the air flow controlling components and filter element need to have a break-through in the currently defective technology and provide a design and consideration in overall manner vision so as to fulfill the demands in the market.
The invention is advantageous in that it provides an air circulator which guides the air to flow in conversion direction before discharging so as to increase the mobility and fluidity of the flowing air and improve the quality of the air.
Another advantage of the invention is to provide an air circulator, wherein the flowing air is guided to turn and flow through a flowing path from bottom to top, wherein the flowing path has a turning corner with a predetermined turning angle to improve the air mobility and fluidity by changing the flowing direction of flowing air.
Another advantage of the invention is to provide an air circulator which collects outside air at a lower portion thereof and discharges the air upwardly in a spiral manner, wherein the inletting air from the bottom is sucked and driven to flow upwardly and spirally for a farer distance to increase the circulation range thereof.
Another advantage of the invention is to provide an air circulator providing better air purifying effect by enabling the inletting air to be deposited at the turning corner and, in addition, providing a filter element at the turning corner for high-efficient filtering.
Another advantage of the invention is to provide an air circulator that purifies inletting air at the lower portion and upwardly sucks and delivers the purified air to discharge so as to reduce the possibility of repeatedly purifying the purified air and thus enhance the air purification efficiency of the environment.
Another advantage of the invention is to provide an air circulator, wherein the inletting air is purified and delivered upwards to discharge purified air up to a position with a predetermined height to meet the actual living need of people without the need to elevate the placing height of the air circulator.
Another advantage of the invention is to provide an air circulator comprising at least a filter unit which can be detached from a lower portion thereof by directly removal operation without lateral movement or shaking, so as to avoid adverse effect to the surrounding environment and reduce the possibility of secondary air pollution while replacing the filter unit.
Another advantage of the invention is to provide an air circulator comprising a power assembly at a lower position that guides the air to deliver upwards from bottom to top while the filter unit is provided at the lower portion lower than the power assembly to provide a relatively clean working environment for the power assembly that decreases the cleaning cycle and increases the service life of the air circulator.
Another advantage of the invention is to provide an air circulator which power assembly is disposed along an outletting direction of the air being guided to flow to avoid interference to air filtration, that improves the mobility and fluidity of the air without affecting its filtration effect.
Another advantage of the invention is to provide an air circulator which comprises a control panel for the power assembly provided on a top side of the air circulator, adjacent to the outlet of the discharging air, to facilitate the controlling operation of the power assembly while reducing adverse effect of the flowing air by the power assembly and ensuring the strengthen of the mobility and fluidity of the flowing air.
Another advantage of the invention is to provide an air circulator, wherein the electrical wiring of the power assembly is arranged in compact configuration to reduce the influence of the air flowing path, minimize the occupying space of the power assembly, and increases the reliability and stability of electrical wiring of the power assembly.
Another advantage of the invention is to provide an air circulator, wherein both the arrangement of the electrical wiring and the supporting mechanism of the power assembly provide a guiding effect to the flowing air that assists the guidance of pushing the outletting flowing air.
Another advantage of the invention is to provide an air circulator which can provide additional functions, such as humidification, fragrance, and etc., by replacing the filter with other functional unit or by using a filter with additional function.
Another advantage of the invention is to provide an air circulator having a light weight and compact size for ease of carrying and placing in various locations in a room to promote air circulation in different regions of the room that prevents the use of the high power and the waste of energy.
Additional advantages and features of the invention will become apparent from the description which follows, and may be realized by means of the instrumentalities and combinations particular point out in the appended claims.

Preferred embodiments are provided in the following description only as examples and modifications will be apparent to one skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.
Referring to
When the power assembly 20 is operated to activate by electrical power to suck air into the airflow channel 100, surrounding air near the air inlet 1110 is driven into the airflow channel 100 through the air inlet 1110 radially and flows upwardly from the bottom of the airflow guiding housing 10. The airflow channel 100 has an airflow turning portion 1001 where the inletting air through the air inlet 1110 will turns a predetermined angle and flow upwardly towards the air outlet 1210 to discharge from the airflow guiding housing 10. In other words, the power assembly 20 guides the air outside the airflow guiding housing 10 to flow into the airflow guiding housing 10 via the air inlet 1110 and flow towards the air outlet 1210 along the airflow channel 100, wherein the radially inletting air will be guided by the airflow channel 100 to turn a predetermined angle to flow longitudinally and upwardly towards the air outlet 1210 to discharge while maintaining the mobility and fluidity of the air flow.
Since the airflow channel 100 is started from a radial direction of the airflow guiding housing 10 and ended with an axial direction of the airflow guiding housing 10, the flowing air will turn a predetermined angle at the airflow turning portion 1001 of the airflow channel 100 due to the suction force provided by the power assembly 20 and the guidance of the airflow channel 100. In other words, the air is pushed from the bottom of the airflow guiding housing 10 and delivered to the top of the airflow guiding housing 10 by the power assembly 20 installed in the airflow guiding housing 10.
Referring to
Furthermore, according to the preferred embodiment, although the flowing air is guided to turn the predetermined angle, form radially to upwardly, at the airflow turning portion 1001 which can provide an air purifying effect that dust particles heavier than air will fall and precipitate to the bottom of the airflow guiding housing 10 during the angle turning of the air flowing, the air circulator is adapted to further comprise an air filter 30 disposed in the bottom of the airflow guiding housing 10 and positioned in the purifying chamber 110 adjacent to the air inlet 1110, so that the air flowed into purifying chamber 110 through the air inlet 1110 is immediately forced to flow through the air filter 30 and thus filtered by the air filter 30 before flowing through the airflow turning portion 1001, as shown in
According to the preferred embodiment, the power assembly 20 is installed in the airflow channel 100 of the airflow guiding housing 10 and positioned on top of the purifying chamber 110 to provide a suction power to drive the air flowing into the airflow channel 100 via the air inlet 1110 and deliver the air flowing out the airflow channel 100 through the air outlet 1210.
According to the preferred embodiment, the airflow guiding housing 10 is in cylindrical shape and adapted for receiving the air filter 30 at the bottom of the airflow guiding housing 10. In particular, the air filter 30 is disposed in an outer corner portion of the purifying chamber 110 of the airflow channel 100 while its outer ring surface is adjacent to the air inlet 1110 which has a plurality of inlet slots 1111 spacedly and vertically formed in a lower peripheral side of the airflow guiding housing 10, wherein the inner space surrounding by the inner surface of the air filter 30 in the purifying chamber 110 forms the airflow turning portion 1001 of the airflow channel 100, such that the outside air radially and traversely flowing in via the air inlet 1110 and passing through air filter 30 enters the airflow turning portion 1001 and the suction force of the power assembly 20 mounted above the air filter 30 will force and drive the purified air to turn the predetermined angle (i.e. 90 degrees) and flow upwardly and vertically into the guiding chamber 120.
In other words, the flowing path of the air is arranged to change direction at the airflow turning portion 1001 of the airflow channel 100 after the filtration of the air filter 30 that substantially helps the purification of the air and slows down the flowing speed of the air within the airflow channel 100 before flowing into the guiding chamber 120. It is worth mentioning that, due to the coaxial arrangement of the airflow channel 100 with the airflow guiding housing 10 while the air inlet 1110 is formed at the lower peripheral side of the airflow guiding housing 10 and the air outlet 1210 is formed at the top side of the airflow guiding housing 10, the airflow guiding housing 10 can be constructed simply in cylindrical shape and the power assembly 20 can be mounted simply along the airflow channel 100 that minimizes the size of the air circulator and enables the air filter 30 to be installed in the purifying chamber 110 adjacent to the air inlet 1110 to filter the inletting air immediate from the air inlet 1110 and drive the filtered air to turn from traverse direction to axial direction and flow out through the air outlet 1210 without increasing the complexity of the air filter 30 and the air circulator while improving the air purifying efficiency of the air circulator of the present invention.
Referring to
In the preferred embodiment, referring to
When the power assembly 20 is operated to be actuated, air outside the inlet case 11 is sucked and collected into the purifying chamber 110 through the air inlet 1110, and the inletting air is drawn to flow through the purifying chamber 110 and to turn from traverse direction to upward direction at the airflow turning portion 1001 of the purifying chamber for purification by deposition and/or filtration through the air filter 30. Then, the power assembly 20 will draw and deliver the purified air into the guiding chamber 120, wherein the purified air will be guided to flow upwardly through the guiding chamber 120 in the spiral manner and discharge out of the outlet case 12 through the air outlet 1210 provided on top of the outlet case 12.
More specifically, the outlet case 12 comprises a guiding frame 121 and a power supporting frame 122, as shown in
Furthermore, as shown in
More specifically, the fan unit 22 comprises a blade unit 221 and a motor 222 which is connected to the blade unit 221 and controlled by the control unit 23 to drive the blade unit 221 to rotate to provide the suction force for drawing air from bottom to top upwardly.
In other words, the rotation speed, the rotation direction and other performance of the motor 222 and the fan unit 221 can be set by operating the control panel 24. The blade unit 221 is driven by the motor 222 is rotated to drive the air flowing in the airflow channel 100.
Referring to
In other alternative modes, other types of air filter 30 may be used and disposed in the base groove 1130 of the bottom base 113. For example, the air filter 30 can be a wet-type filter, a fragrance type filter and etc. To a wet-type filter, the filtering component of the air filter is soaked with fluid such as water to contain a predetermined moisture so that when the air flowing therethrough will increase its humidity, To a fragrance type filter, the air filter 30 as shown in drawings is replaced by simply adding water, flavor additives, or etc. into the base groove 1130 to add moisture to the inletting air before turning direction to flow up at the airflow turning portion 1001. Of course, the fragrance type filter can be used with the air filter 30 at the same time, wherein in addition to the air filter 30 disposed in the purifying chamber 110, water or favor additives are added in the base groove 1130.
The inlet case 11 further comprises a central connector 112 and a fastener 114. The central connector 112 has an elongated shank having a length generally equal to the height of the surrounding shell 111 of the inlet case 11, a threaded first end 1121 coaxially extended out a central hole 1132 of the bottom base 113 to be fastened by the fastener 114 and a second end 1122 coaxially extended upwardly and configured to be coaxially secured to the bottom of the outlet case 12. The fastener 114 is a nut body adapted to screw with to the first end 1121 of the central connector 112 so as to stably affixed the bottom base 113 with the surrounding shell 111 to form the inlet case 11 and fastened the inlet case 11 with the outlet case 12 while holding the air filter 30 within the purifying chamber 1110 of the inlet case 11.
Simply by tightening the screwing of the first end 1121 of the central connector 112 with the fastener 114, not only the bottom base 113 is securely connected with the surrounding shell 111 to cover the purifying chamber 110 within the surrounding shell 111, the inlet case 11 can also be tightly fastened with the outlet case 12 coaxially to form the airflow guiding housing 10 at the same time while the space around the central connector 112 within the surrounding shell 111 is covered by the bottom base 113 and defined as the purifying chamber 110 for enabling the air filter 30 to be disposed therein and allowing the inletting air drawn in though the air inlet 1110 to flow through the air filter 30 radially for air purification and turn a flowing direction upwardly into the guiding chamber 120 at the airflow turning portion 1001 defined between the inner surface of the air filter 30 and the outer cylindrical wall of the central connector 112.
Simply by unscrewing the fastener 114 from the first end 1121 of the central connector 112, the bottom base 113 is can be detached from surrounding shell 111 to open the purifying chamber 110 so that one can remove or replace the air filter 30, add water or additive in the base groove 1130 of the bottom base 113, detach the inlet case 11 with the outlet case 12 by disconnecting the second end 1122 of the central connector 112 with the outlet case 12 for cleaning or repairing purpose.
Preferably, referring to
After the fan unit 22 of the power assembly 20 is actuated to rotate, the flowing air is drawn and guided upwardly and outwardly within the guiding chamber 120 from the purifying chamber 110. It is worth mentioning that the power supporting frame 122 separates the guiding chamber 120 with the electrical components, including the control unit 23 and the power supply 21 of the power assembly 20. In other words, the fan unit 22 is supported in the guiding chamber 120 by the power supporting frame 122 to drive and guide the air flowing through the guiding chamber 120 while the electrical components, electric wiring 25 and other circuit elements are isolated and concealed in the power supporting frame 122 from the guiding chamber 120 of the airflow channel 100, without affecting or blocking the flowing path of the air, so as to stabilize and effectively guide the air flow along the airflow channel 100, enhance the reliability of the power assembly 20 and prolong the service life span of the air circulator.
As shown in
The support frame 1211 is a tubular frame having a diameter smaller than that of the guiding shell 121 and a height shorter than the height of the guiding frame 121, such that the support frame 1211 is adapted to be mounted on a lower portion inside the case shell 1214, as shown in
It is worth mentioning that, when the air filter 30 is installed in the purifying chamber 110, the lower half of the guiding chamber 120 defined by the support frame 121 has a volume larger than that of the interior space defined between the central connector 112 and the inner surface of the air filter 30, that would additionally provide a suction force for and speed up the air flowing from the purifying chamber 110 into the guiding chamber 120, which also enhances the drawing force to drive the air entering from the air inlet 1110 to pass through the air filter 30 into the airflow turning portion 1001 of the purifying chamber 110.
The outlet frame 1213 comprises a circular outer outlet rim 12131 adapted to be connected to the top end of the case shell 1214 of the outlet case 12, as shown in
The guiding wall 1212, as shown in
In other words, the axes of the power supporting frame 122 and the support frame 1211 are aligned to the second end 1122 of the central connector 112 of the inlet case 11. The bottom end edge of the guiding wall 1212 is connected to the support frame 1211, and the top end edge is connected to the outlet frame 1213. Due to the arrangement of the airflow guiding ribs 12114 and the guiding inlet 12113 of the guiding frame 1211, the air driven by the fan unit 22 of the power assembly 20 from the purifying chamber 110 will be guided by the airflow guiding ribs 12114 to flow into the guiding chamber 120 through the guiding inlet 12113 in a helical manner and be guided by the airflow guiding surface 12121 of the guiding wall 1212 to flow out through the airflow outlet 1210 provided in the outlet frame 1213. Such helical flow of the air in the guiding chamber 120 not only can speed up the air flow, but also can enhance the suction force of the fan unit 22 to draw air flowing from the purifying chamber 110 and help the air to flow up and discharge through the air outlet 1210 on top of the airflow guiding housing 10.
The blade unit 221 of the fan unit 22 is rotatably mounted to the motor 222 of the fan unit 22. The power supporting frame 122 comprises a blade supporter 1221 for rotatably supporting the blade unit 221 of the fan unit 22 with bearing mechanism so that the blade unit 221 can be driven to rotate by the motor 222. The power supporting frame 122 further comprises a power supporter 1222 arranged to be mounted on an outer side of the support frame 1211 for supporting the power supply 21 which is electrically connected with the motor 222 to supply electric power. The top end of the cup shape frame body 1220 of the power supporting frame 122 forms a panel supporter 1223 allowing the control unit 23 mounted thereon while the control panel 24 is attached on top of the control unit 23, as shown in
Referring to
As mentioned above, the power supporter 1222 can be affixed on the support frame 1211 and provided on the outside of the guiding wall 1212 while the guiding chamber 120 is formed inside the support frame 1211 and the guiding wall 1212. In particular, according to the preferred embodiment, the power supporter 1222 is integrally molded on the support frame 1211 outside the guiding chamber 120. In other words, the power supply 21 contained in the power supporter 1222 is isolated from the guiding wall 1212 and the guiding chamber 120, so as to avoid interaction between the flowing air and other electrical components.
In addition, the blade supporter 1221 which is adapted to affix the blade unit 221 of the fan unit 22 in the support frame 1211 in position forms a bridge to electrically connect the power supply 21 in the power supporter 1222 with the motor 222 of the fan unit 22 for providing electric power to actuate the motor 222 to drive the blade unit 221 to rotate to provide a balance suction force in the lower half of the guiding chamber 120 to draw air flowing from the purifying chamber 110 into the guiding chamber 120 of the airflow channel 100.
Preferably, the blade supporter 1221 is designed to be mounted relatively on the first end 1221 of the cup shape frame body 1220 of the power supporting frame 122 within the guiding chamber 120, so the air in the purifying chamber 110 is driven to flow upwardly into the guiding chamber 120 by the rotating blade unit 221 that also provides a suction force in the purifying chamber 110 to draw air from outside into the purifying chamber 110 through the air inlet 1110. In other words, the blade unit 221 is placed in a central position of the airflow channel 100. Of course, depending on the design, the position of the blade unit 221 may be adjusted by the position of the blade supporter 1221.
According to the preferred embodiment, the blade supporter 1221 is mounted on the bottom end of the cup shape frame body 1220 of the power supporting frame 122, wherein the control unit 23 is mounted on the panel supporter 1223 which is the upper portion of the cup shape frame body 1220 of the power supporting frame 122 and electrically connected to the motor 222 of the fan unit 22 mounted to the blade supporter 1221 with the electric wiring 25 extending in the receiving cavity 1225 of the cup shape frame body 1220 of the power supporting frame 122. Preferably, the electric wiring between the power supply 21 and the control unit 23 is extended from the power supporter 1222 to the panel supporter 1223 via the blade supporter 1221. Such that the electrical components and electric wiring of the air circulator of the present invention are arranged along a central path and concealed within the power supporting frame 122 according to the preferred embodiment so as to isolate from the air flowing in the guiding chamber 120 of the airflow channel 100 to provide an electrical compact arrangement and achieve better and easier operation and performance for the air circulator. Such concealing arrangement to the electrical components and electric wiring in the guiding chamber 120 is especially important when the air is humidified to contain desired moisture during the purifying of the air in the purifying chamber 110.
The control panel 24 is mounted on the panel supporter 1223 of the power supporting frame 122 and positioned above the control unit 23, which substantially covers and secured all electrical components, including the control unit 23, the motor 222 and the electric wiring 25, disposed within an enclosed environment, i.e. the receiving cavity 1225. The control unit 23 is electrically connected to the control panel 24 upwardly and the blade unit 221 and motor 222 of the fan unit 22 downwardly through the receiving cavity 1225.
It is worth mentioning that the outer guiding surface 1224 of the cup shape frame body 1220 of the power supporting frame 122 is gradually and smoothly extended upwardly and outwardly from the bottom end to the top end of the cup shaped frame body 1220, wherein the outer guiding surface 1224 and the inclined airflow guiding surface 12121 of the guiding wall 1212 define the guiding chamber 120 therebetween. The curvature of the outer guiding surface 1224 and the airflow guiding surface 12121 provides a guiding effect to the air flowing upwardly through the guiding chamber 120 which substantially drives the air flowing upwards and outwards when discharging through the air outlet 1210.
According to the preferred embodiment, the circulation of air is illustrated in
In particular, the air is driven to enter the purifying chamber 110 through the air inlet 1110 of the surrounding shell 111. After being filtered radially through the air filter 30, the air is forced to flow towards the central connector 112. In other words, the air around the surrounding shell 111 is capable of flowing in contact with the air filter 30 in every angle and then is gathered to the central portion of the surrounding shell 111, i.e. the airflow turning portion 1001 of the purifying chamber 110.
Accordingly, referring to
In view of above, the purifying chamber 110 and the guiding chamber 120 are coaxially aligned from bottom to top inside the airflow guiding housing 10 to define the airflow channel 100 therein. Since dust and particles in the air usually sink to the lower portion of the air in a specific area due to gravity, the air inlet 1110 is designed to be provided of the around the peripheral side of the surrounding shell 111 of the inlet case 11 connected under the outlet case 12 while the air outlet 1210 is provided at the top side of the outlet case 12 that is the topmost position of the airflow guiding housing 10, allowing the airflow channel 100, so as to obtain a longest airflow channel 100, the longest air flowing path and the best air circulation effect for the airflow guiding housing 10. Also, the arrangement of the electrical components of the power assembly 20, including the power supply 21, fan unit 22, the control unit 23, and electric wiring 25, is positioned the central portion of the guiding chamber 120 of the outlet case 12 by containing within the cup shape frame body 1220, such that the electrical components can be concealed and protected by the cup shape frame body 1220 while allowing the user to operate the air circulator simply and easily at the control panel 24 mounted on the top side thereof and feel the outletting air emitted from the air outlet 1210 around the control panel 24, and that the air flowing up through the guiding chamber 120 can also be guided upwardly and outwardly around the outer guiding surface 1224 of cup shape frame body 1220. Such arrangement not only can ensure the air circulator of the present invention to have a relatively compact size and balanced lighter weight while all components are symmetrically arranged, but also provide an effective airflow channel 100 for guiding the air to flow in at a lower position radially via the air inlet 1110, to turn 90 degrees to flow up at the airflow turning portion 1001 of the purifying chamber 110 to enhance purifying of the inletting air, to drive the air to flow from the purifying chamber 110 into the guiding chamber 120 upwardly and spirally by the airflow guiding ribs 12114 to enhance the delivery of the air upwardly, to guide the air to flow out upwardly and outwardly by means of the cup shape frame body 1220 that contains and protects the electrical components from moisture in the air, and to flow out the air circulator upwardly, outwardly and helically by means of the airflow outlet ribs 12132 for better air circulation ability and larger coverage space of the air circulator of the present invention.
The outer guiding surface 1224 and the inclined airflow guiding surface 12121 can be smooth surfaces. In other alternative embodiments, the guiding surface 1224 and/or inclined airflow guiding surface 12121 may have grooves or protrusions, extended upwardly and spirally, provided for desired air guiding purposes. Person skilled in the art may take advantage of designing various shapes and curvatures of the outer guiding surface 1224 and the inclined airflow guiding surface 12121 to perform different predetermined guiding and air flowing effects.
According to the preferred embodiment, referring to
In an alternative mode of preferred embodiment of the present invention, two or more inlet cases 11 superposed with each other can be used as shown in
Since the two surrounding shells 11 have two purifying chambers 110 and respectively accommodate two air filters 31, 32, the purifying effect and air circulating ability of the air circulator of the present invention can be doubled.
