Description

Fan guiding structure

The present invention relates to a fan flow guiding structure, and more particularly to a fan flow guiding structure that can direct airflow to the sides of the fan.

According to the conventional fan, such as a general vertical fan or a ceiling fan, the majority of the blades are rotated to force the flow of the gas, but the airflow direction is mainly located in the axial direction of the fan, and the convection efficiency is lower at the position of the fan. The heat energy at the position cannot be effectively dissipated; in addition, the fan and the ceiling fan are limited by the rotation angle before leaving the factory, so that the range of the cold air blowing is quite limited, for those who are located in the indoor space at a corner position, It is often the case that the fan or the ceiling fan structure is often the most criticized.

To this end, how to solve the long-standing lack of conventional fans is a problem that the industry needs to face.

The main object of the present invention is to provide a flow guiding structure that can effectively guide the airflow to the side of the fan to increase the angle of diffusion of the airflow.

Another object of the present invention is to provide a flow guiding structure that can be combined with an airflow angle of an existing fan or a ceiling fan.

The fan guiding structure provided for the above purpose is provided on a fan, the fan guiding structure comprises at least one deflector and at least one connecting portion, the deflector is arranged to span the fan outlet position The baffle is located at the center side of the fan and does not overlap the center of the fan, and the baffle extends obliquely outward to guide the airflow to the side of the fan, and the connecting portion is used for guiding The flow plate is attached to the fan.

Thereby, the airflow formed by the fan is not only collected in the axial direction of the fan, but can be appropriately diffused to the side of the fan, thereby greatly increasing the fan air supply angle and enhancing the convection efficiency around the fan.

In the following, the structural features of the present invention and the intended effects thereof will be described by way of a preferred embodiment, and are not intended to limit the scope of the invention as claimed.

Please refer to Figure 1 and Figure 2. In the preferred embodiment of the present invention, the fan flow guiding structure is used in combination with a fan. The fan defines a vertical fan and a ceiling fan suspended from the ceiling. The embodiment is described in connection with a vertical fan.

The fan flow guiding structure of the present invention comprises at least one baffle 10 and at least one connecting portion 20, more specifically, the number of the baffles 10 is two, and the connecting portion 20 is also two.

The baffle 10 is disposed in front of the fan outlet position, and the baffle 10 is located on the center side of the fan without overlapping the center of the fan, thereby avoiding completely blocking the axial airflow of the fan. The panel 10 extends primarily obliquely outwardly to direct airflow to the sides of the fan. Preferably, the deflector 10 has a curved surface that is used to help direct airflow outward. In this embodiment, the two baffles 10 are symmetrically disposed on both sides of the center of the fan, thereby allowing the airflow to be uniformly diffused.

The connecting portion 20 is configured to connect the baffle 10 to the fan. In the present embodiment, the connecting portion 20 includes two fastening blocks 21 connected to the deflector 10 respectively. Two sides, and the fastening block 21 is fastened on the mesh cover 1 of the fan, so that the user can quickly disassemble and install the fan flow guiding structure according to requirements to meet different environments; and the fan of the present invention The diversion structure can be combined with the existing vertical fan or ceiling fan activities by the connecting portion, so that the consumer can purchase the fan guiding structure of the present invention with a minimum amount of money, thereby expanding the blowing angle of the fan. Preferably, the deflector is pivoted relative to the buckle block to change the tilt angle of the deflector relative to the fan net cover to obtain different blow angle adjustment effects.

Again, please refer to Figure 3 and Figure 4. The fan guiding structure used in combination with the ceiling fan comprises at least one fan-shaped baffle 10, and more specifically, the baffle 10 is more effective as shown in the drawing (more preferably, the fan-shaped width of the baffle is The activity is collected and combined, and the profitable consumer adjusts the width of the deflector according to the demand to obtain different wind power effects. The top of the fan-shaped deflector 10 forms a shape corresponding to the joint of the ceiling fan. The connecting portion 20 and the connecting portion 20 disclosed in FIG. 4 are configured to match the hollow ring plate of the circular structure below the ceiling fan. Of course, depending on the location of the ceiling fan, the connecting portion needs to be correspondingly designed according to the shape of the joint portion. The connecting portion 20 adopts a hollow ring plate corresponding to the circular structure below the ceiling fan, and the deflector 10 can be adjusted at an angle of 360° with respect to the ceiling fan.

The fan-shaped baffle 10 is coupled to the ceiling fan through the connecting portion 20, so that it can be symmetrically disposed on both sides of the center of the ceiling fan (fan). The two baffles 10 further include two connecting columns extending from the connecting portion 20. 22 and at least one support column 23, which are respectively connected to both sides of the baffle 10 and the fan near the center, between the inner edge of the baffle 10 and the two connecting columns 22, as needed A hollow portion 24 can be opened for airflow at the center of the fan (the airflow is basically passed between the two fan-shaped baffles), and the support column 23 is located between the two connecting columns 22, and the support column The 23 series is coupled to the inner edge of the baffle 10 and the center of the fan, thereby maintaining the structural strength of the baffle and preventing it from being shaken by the wind.

The fan flow guiding structure of the invention can effectively improve the problem that the air supply angle of the conventional fan is limited, and the arrangement of the deflector plate helps to expand the lateral air supply angle, and at the same time, the gas flow in the axial direction can be properly maintained, at the expense of Under the premise of minimum axial air supply, the air supply angle is maximized to meet the needs of users.

It can be seen from the above that the present invention not only has a novel and practical structure, but also has the effect of making remarkable progress, conforms to the relevant provisions of the Patent Law, and files a patent application according to law, so that the Office can approve the patent as soon as possible.
