Description

Technical Field

[0001] The invention relates to a ceiling fan, and in particular to a ceiling fan. Background Art

[0002] A ceiling fan is also called a ceiling fan. It is mainly used in places suitable for installing air conditioners, such as kitchens and bathrooms. Compared with ordinary fans, ceiling fans are more convenient and the wind direction is adjustable. For example, when cooking in the kitchen, you can adjust the ceiling fan to ensure that it can cool down without affecting the cooking.

[0003] A ceiling fan is also called a ceiling fan. It is mainly used in places suitable for installing air conditioners, such as kitchens and bathrooms. Compared with ordinary fans, ceiling fans are more convenient and the wind direction is adjustable. For example, when cooking in the kitchen, you can adjust the ceiling fan to ensure that it can cool down without affecting the cooking.

[0004] A patent with the publication number CN207920930U and the name of "A ceiling-mounted blowing fan" was published on September 28, 2018. The invention discloses a ceiling-mounted blowing fan, which belongs to a blowing fan. The existing blowing fans use AC motors, which result in high energy consumption and cannot be fully stepless speed regulation. The present invention uses a cross-flow impeller and drives it with a DC motor. An air outlet is set on the mask and a guide vane is set at the air outlet. The guide vane is driven by a stepper motor to change the wind direction. The DC motor and the stepper motor are controlled by the control circuit. When the DC motor is started by the control circuit to drive the impeller, the direction of the guide vane can be intelligently adjusted to change the air outlet direction of the mask. In addition, a working indicator device is set on the mask to display the working status on the mask during operation. The present invention controls the DC motor to drive the impeller through the control circuit, which can not only intelligently adjust the speed, but also reduce energy consumption; the swing direction of the swing blade is intelligently adjusted to achieve the purpose of adjusting the wind direction.

[0005] This invention adopts a cross-flow wind wheel, which can enhance the wind output intensity, and can also adjust the direction of the guide vanes through the control circuit to increase the wind output range. It can also intelligently adjust the rotation speed through the control circuit to reduce energy consumption.

[0006] However, the existing coolers have the following problems:

[0007] 1. The lighting panel is directly illuminated and cannot achieve the atmosphere lighting effect;

[0008] 2. The humidity in kitchens and bathrooms is relatively high, which is easy to breed bacteria, and there is no disinfection and sterilization structure on the air conditioner;

[0009] 3. The position of the motor installed in the box is closed, and the motor is not easy to dissipate heat. Long-term operation will affect the performance of the motor and reduce the life of the motor;

[0010] 4. During the assembly process, the wind wheel, motor, etc. must be fixed one by one. The fixing structure and fixing effect are poor. The wind wheel rotates at high speed during operation, which may cause looseness.

[0011] 5. There is also an air collecting plate between the swing blade and the wind wheel. The wind blown out by the wind wheel will be lost when passing through the air collecting plate, which will affect the air output effect.

[0012] Based on the above situation, the present invention proposes a ceiling fan, which can effectively solve the above problems. Summary of the invention
