Description

The present application relates to the technical field of consumer electronics, and more particularly to a wind guide structure and a fan.

This application claims priority on the basis of a Chinese patent application filed on August 22, 2017 with the application number 201710724438.0 and the invention title "wind guide structure and fan", the disclosure of which Take everything here.

The tower fan is a new fan that has become a popular product recently, and its unique columnar shape occupies a beautiful and small area, and the wind generated by the cross flow fan is more natural and soft, so it is preferred by many consumers. It is rare. The air outlet of the conventional tower fan is located in the front of the body, and the bar lattices at the air outlet are all vertical bar-shaped structures installed from top to bottom, and the air outlet lattice is fixed and installed. The fan of the present invention sends air by rotating the tower fan with respect to its base, and the inventor of the present application discovered the following in designing the product. The width direction of the bar grid is provided directly in front of the air outlet, and the wind that has entered the case from the intake port on the rear surface of the body part bypasses the cross flow fan blades provided in the center of the case and leaves the swirl chamber. Since it is blown out from the blower opening after that, the flow direction of the airflow before reaching the blower opening is directed diagonally forward of the tower fan due to inertia, and the airflow that is about to be blown out from the blower opening is provided vertically like this. It is hindered by the generated grid and collides with the grid, and loses a large amount of kinetic energy, resulting in a low velocity of the blown air, a short blowing distance, and a poor user experience.

Therefore, the problem to be solved by the present application is to eliminate the defect that the speed of the air blown from the fan is low due to the unreasonable lattice structure in the prior art and the blowing distance is short, and the blowing speed and the blowing distance are Provide a wind guide structure that is advantageous for improvement.

At one end along the width direction of the wind plate, there is a bent portion bent in the direction in which the wind blows.

The bent portion is provided in contact with the blowing wind.

The wind guide plate provided on the windward side has a larger degree of bending at the bent portion than the wind guide plate provided on the leeward side.

The degree of bending of the bent portions of the plurality of wind guide plates gradually decreases from the side closer to the windward side to the side closer to the leeward side.

The other end of the baffle plate along the width direction is a lead-out portion adjacent to the bent portion, and the extending direction of the lead-out portion is provided perpendicular to a vertical plane facing the wind guide structure.

The plurality of baffle plates are provided so as to extend in the same direction.

The portion is provided facing the inside of the case, and the extending direction of the baffle plate is aligned with the axial direction of the blower.

The fan is a tower fan, and the blower is a cross flow blower.

The case has a cylindrical shape, the air blowing surface formed on the air blowing port is an arc surface, and the other end of the air guide plate along the width direction thereof is a lead-out portion adjacent to the bent portion. Is provided perpendicular to a vertical plane that passes through the center of the arc surface and is in contact with the arc surface.

The case further includes a base provided below the case, and the case is reciprocally rotatable with respect to the base.

According to the technical solution of the present application, there are the following merits.

1. The air guide structure provided in the present application includes a frame body and a plurality of air guide plates provided in the frame body, and both ends of the air guide plate along the longitudinal direction are connected to the frame body, respectively, and at least one If there is a bent part that is bent toward the direction in which the wind blows at one end along the width direction of the two baffle plates and the wind source is not installed directly in front of the baffle structure, the air flow will be Bending from the side of the wind guide structure to the wind guide structure, the airflow blown from the wind source first contacted the bent part, and the bent part of the wind guide plate was bent in the direction in which the wind blows. The included angle between the wind and the blowing direction of the wind can be reduced, and the collision loss that occurs when the airflow comes into contact with the bent portion can be reduced, which is advantageous in maintaining the kinetic energy of the airflow and improves the air blowing speed and the air blowing distance. To improve the user experience.

2. The air guide structure provided in the present application is provided so that the bent portion is in contact with the blowing air, and the collision loss generated when the air flow comes into contact with the bent portion is maximally reduced to gradually blow the air flow. Discharge from mouth.

3. In the air guide structure provided in the present application, the bending degree of the bent portion of the wind guide plate provided on the windward side is larger than the bending degree of the bent portion of the air guide plate provided on the leeward side. This is because although the bent portion of the baffle plate can reduce the loss of kinetic energy of the airflow, the effect of adjusting the air blowing direction by the baffle plate is also reduced, and the blown air is greatly spread to one side along the bent portion. It is lopsided, in order to correct the air flow direction, the bending degree of some of the bent portions of the air guide plate must be adjusted to a small degree, and when the wind source is provided on the side of the air guide structure, For example, in the case of a swirl chamber blower, if the air volume on the leeward side is larger than the air volume on the upwind side and the bending degree of the bent part of the wind guide plate provided on the leeward side is reduced, the air flow rate is originally small and close to the windward side. It is possible to prevent the decrease of the air volume of the airflow, to guarantee the airflow uniformity among multiple air guide plates as much as possible, and to effectively correct the airflow direction, and the airflow direction after correction is clearly in front of the airflow guide structure. Returning to this, the air flow direction, the air flow direction and the air flow distance are guaranteed, the air flow direction is corrected, the air flow amount and the air flow direction are balanced, and the air flow effect of the air guide structure can be significantly improved.

4. In the wind guide structure provided by the present application, the bending degree of the bent portions of the plurality of wind guide plates gradually decreases from the side closer to the windward side to the side closer to the leeward side, and the air volume becomes stronger from the windward side to the leeward side. The bending degree of the bent portion of the baffle plate where the air volume is large is small, and it is more rational to install the bent portion of the baffle plate by reducing the collision loss and correcting the air flow direction.

5. The wind guide structure provided in the present application is a lead-out portion adjacent to the bent portion at the other end along the width direction of the wind guide plate, and the lead-out portion extends in a direction perpendicular to the vertical plane facing the wind guide structure. Provided, the airflow is relaxed by the bent portion and guided to the outlet portion, and in order for the consumer located directly in front of the air guide structure to feel the front air blowing, the outlet portion must further correct the air blowing direction. Although it is necessary to fold the lead-out portion relative to the bent portion, it is advantageous in correcting the air flow direction, but since the collision loss due to such installation is large, the lead-out portion of the baffle plate faces the air guide structure. By providing the air flow perpendicularly to the vertical plane, the air flow rate can be guaranteed and the air flow direction can be corrected.

6. The air guide structure provided in the present application has the outward expansion structure on the side away from the bent portion of the frame body, and the outward expansion structure is advantageous for increasing the air blowing angle of the air guide structure.

7. The fan provided in the present application includes a case having a blower opening, a blower provided in the case, and a wind guide structure provided at the blower opening, and a frame of the wind guide structure is attached to the blower opening. The bent part is provided facing the inside of the case, the blast is along the tangent line of the blower, the extending direction of the baffle plate is aligned with the axial direction of the blower, and the baffle structure makes the collision loss of the blast effective. In addition to reducing the air flow direction, the air flow direction is well corrected, the air flow speed of the fan is high, the air flow distance is long, the air flow direction is accurate, and the product experience is improved.
