Description

Technical Field

[0001] The present invention relates to a fan assembly.

Background Art

[0002] Conventional household fans used for the purpose of thermal comfort and / or environmental or temperature control usually generate a relatively stable air flow. However, in the study of thermal comfort, it has been shown that natural wind or gentle breeze can bring a greater sense of cold than these stable artificial air flows. In particular, both field studies and control experiments have suggested that natural gentle breeze can bring a greater thermal response or warm feeling to humans when compared with a certain air flow.

[0003] Therefore, it is desirable to provide a fan assembly that can generate an air flow that reproduces the flow characteristics of natural wind, and thus can be considered to provide a more comfortable sense of cold than that provided by a stable artificial air flow. However, considering the seemingly disorderly or irregular nature of the wind and the scale of its fluid mechanism, it is a difficult task to reproduce the natural outdoor air flow in an indoor environment.

Summary of the Invention

Problems to be Solved by the Invention

[0004] An object of the present invention is to provide a fan assembly that can generate an air flow that reproduces the flow characteristics of natural wind, and thus can be considered to provide improved thermal comfort to users. Therefore, the present inventors used the turbulent flow statistical method to develop a wind profile at a typical human height and identified some characteristics representing natural wind at such a height. Next, we compare the characteristics determined for natural wind using conventional vibration methodology. However, it has been determined that it is difficult to generate an airflow with the characteristics required for the present invention. The authors then realistically model the identified properties of natural wind over a range of frequencies relevant to humans. It has been discovered that it is possible to make the airflow oscillate non-periodically in a way that can be simulated virtually. In particular, the inventors have demonstrated that certain characteristics of natural wind are observed in the air at vibration velocities that vary from vibration to vibration. It has been found that this can be reproduced by a fan assembly that can oscillate the air outlet. [Means for solving the problem]

Best Mode for Carrying Out the Invention

[0019] Next, a fan assembly including a nozzle will be described that can generate an air flow that reproduces the flow characteristics of natural wind and can thus be regarded as providing thermal comfort to the user. As used herein, the term "fan assembly" refers to a fan assembly configured to generate and deliver an air flow for purposes of thermal comfort and / or environmental or temperature control. Such a fan assembly can generate one or more of a dehumidified air flow, a humidified air flow, a purified air flow, a filtered air flow, a cooled air flow, and a heated air flow. The fan assembly includes a base disposed to support the fan assembly on a surface, an air flow generator disposed to generate an air flow, and an air outlet disposed to discharge at least a portion of the air flow from the fan assembly, the air outlet being disposed to vibrate relative to the base. The fan assembly further includes a controller disposed to control the vibration of the air outlet relative to the base, the controller being disposed to vary the vibration speed of the air outlet for each vibration.

[0020]

[0021] As used herein, the term "vibration" refers to a motion that repeatedly switches between a motion in a first direction and a motion in a second direction opposite to the first direction. In particular, vibration can include back-and-forth motion between two fixed end points and / or around a fixed center point, but the term "vibration" as used herein is not limited to such a motion pattern. ​​​​​​​​​​​​​​Unintended, including forward and backward movement between variable endpoints, and / or that movement has no fixed center point. Thus, as used herein, the terms "vibration" and "single vibration" refer to complete movement in a specific direction. For example, vibration includes movement in a specific direction that occurs between the immediately preceding and immediately

[0022] following direction changes. As used herein, the term "vibration speed" refers to the speed or rate of vibration (i.e., the speed of movement during vibration). For example, in the case of a fan assembly, the vibration of the air outlet typically involves rotation of the air outlet about the axis of rotation such that the speed at which the air outlet vibrates includes the rotational speed or angular velocity in radians or degrees per second. In that case, as used herein, the term "magnitude of vibration" refers to the size or extent of the vibration. For example, in the case of a fan assembly where the vibration of the air outlet involves rotation of the air outlet about the axis of rotation, the magnitude of vibration will include the angle of vibration / rotation, i.e., the angle through which the air outlet rotates during vibration. As used herein, the term "vibration frequency" refers to the number of individual vibrations

[0023] occurring within a period of time and can be expressed in Hertz (Hz). Thus, the vibration frequency is defined by the combination of the vibration speed and the magnitude of vibration for each vibration. In a preferred embodiment, the controller is arranged to randomly vary the vibration speed of the air outlet for each vibration. In particular, the can, whereby the controller is between the upper limit and the lower limit of the vibration speed is arranged to randomly select the vibration speed. As a further example, the controller is a random number generator is used to select one of a range of values that all have an equal probability of being selected, and then a lookup is performed to identify the vibration speed corresponding to the randomly selected value may be arranged. When using this approach, the controller stores a lookup table containing the vibration speed for each available value, or is preferably configured to be able to access the lookup table, and these vibration speeds are separated at equal intervals from the lower limit of the vibration speed to the upper limit of the vibration speed.

[0024] In any embodiment, the controller is arranged to vary both the vibration speed and the magnitude of the vibration for each vibration of the air outlet. In that case, the controller can be arranged to randomly vary the magnitude of the vibration of the air outlet for each vibration. In particular, the controller can be arranged to randomly select the magnitude of the vibration used for each vibration from within a predetermined range of magnitudes of vibration. For example, this predetermined range of magnitudes of vibration can be defined by the upper limit and the lower limit of the magnitude of the vibration, whereby the controller can be arranged to randomly select the magnitude of the vibration that is between the upper limit and the lower limit of the magnitude of the vibration.

[0025] In a preferred embodiment, the controller is configured to select the parameters for each vibration (e.g., from a predetermined range that approximately corresponds to vibration frequencies of 0.15 Hz to 2 Hz, preferably 0.2 Hz , configured to select (vibration speed and vibration magnitude). In this regard, the frequency range of human perception is usually 0.15 Hz to 2 Hz, while most perceptions are found to be included in 0.2 Hz ~1.5 Hz.

The vibration motor 2206 rotates within corresponding elongated openings in the rotors 2209 and 2210. , 2207. The opposite ends of the outlet bodies 2215, 2216 are then , and are disposed in bearings 2219. Thus, the operable air outlets 2201, 22 The direction of the airflow emitted from each of the vibration motors 2206, 2207 is controlled by the corresponding vibration motors 2206, 2207. can be changed by adjusting the angular orientation of the air outlet channels 2217, 2218.

The user can control the speed of the fan motor 2110, and thus the speed at which air is drawn into the body through the air inlet 2101, by operating the user interface. The air flow passes sequentially through the filter assembly 2300, the air inlet 2101, the impeller housing 2107, and the vent 2102 at the open upper end of the body of the fan assembly 12000, and enters the internal passage 2214 of the nozzle 2200 through the air inlet 2204 disposed at the base 22 05 of the nozzle 2200. Inside the internal passage 2214, the air flow is split into two air flows, which each pass around the body 2208 of the nozzle 2200 in opposite angular directions within the respective straight portions 2209, 2210 of the nozzle body 2203. When the air flow passes through the internal passage 2214 ​​​​​​​​​​​​​k, the air is discharged through both the first air outlet 2201 and the second air outlet 2202. It is done.
