Description

Technical Field

[0001] The utility model belongs to the field of ventilation control, in particular to a low-noise automatic constant-humidity control ventilation fan. Background Art

[0002] A ventilation fan, also known as a ventilator, is an air conditioning appliance that uses a motor to rotate blades, creating airflow and exchanging air between indoor and outdoor spaces. The purpose of ventilation is to remove contaminated air from a room and regulate temperature, humidity, and sensory quality. Ventilation fans are widely used in homes and public spaces.

[0003] Currently, most ventilation fans rely on manual or temperature-controlled airflow control. However, this is not ideal for indoor environments with high humidity fluctuations, or for those used by public spaces. Current room humidity control is typically achieved through mechanical ventilation and exhaust, controlled manually. This relies solely on sensory perception, making it impossible to adjust humidity levels based on actual humidity fluctuations. Manual dehumidification is the only option, resulting in suboptimal results. Therefore, a new, low-noise, automatic constant humidity control ventilation fan is urgently needed to address this challenge. Utility Model Content

[0004] In order to solve the above-mentioned existing problems, the utility model provides a low-noise automatic constant humidity control ventilation fan which starts exhausting when the actual humidity in the room reaches the set value and continues to exhaust until the humidity in the room reaches the set value. It has good humidity control effect and low operating noise.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a low-noise automatic constant humidity control ventilation fan, comprising a terminal, a potentiometer, a ventilation fan motor, a humidity controller and a capacitor. The output end of the terminal is provided with a live wire terminal 1, a live wire terminal 2, a neutral wire terminal and a ground terminal. The potentiometer is connected to the live wire terminal 1, the ventilation fan motor is connected to an end of the potentiometer away from the live wire terminal 1, the input end of the humidity controller is respectively connected to the live wire terminal 2 and the neutral wire terminal, the input end of the humidity controller is respectively connected to the potentiometer and the ventilation fan motor, and the two ends of the capacitor are respectively connected to the potentiometer and the ventilation fan motor.

[0006] Furthermore, a humidity sensor is provided at the input end of the humidity controller.

[0007] Furthermore, the input end of the terminal is connected to 220V, 50HZ alternating current.

[0008] Furthermore, the humidity controller adopts XH-W3005 humidity controller.

[0009] The beneficial effects achieved by the utility model using the above structure are as follows: the low-noise automatic constant humidity control ventilation fan proposed in this solution automatically exhausts air to maintain the humidity in the room, has a good humidity control effect, and has low operating noise.

DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0013] like Figure 1 As shown, the low-noise automatic constant humidity control ventilation fan proposed in this scheme includes a terminal 1, a potentiometer 6, a ventilation fan motor 7, a humidity controller 8 and a capacitor 9. The output end of the terminal 1 is provided with a live wire terminal 2, a live wire terminal 3, a neutral wire terminal 4, and a ground terminal 5. The potentiometer 6 is connected to the live wire terminal 2, and the ventilation fan motor is connected to the end of the potentiometer 6 away from the live wire terminal 2. The input end of the humidity controller 8 is respectively connected to the live wire terminal 2 3 and the neutral wire terminal 4. The input end of the humidity controller 8 is respectively connected to the potentiometer 6 and the ventilation fan motor 7. The two ends of the capacitor 9 are respectively connected to the potentiometer 6 and the ventilation fan motor 7. The input end of the humidity controller 8 is also provided with a humidity sensor 10.

[0015] During specific use, the humidity sensor 10 and the ventilation fan motor 7 are installed indoors, and the humidity value is set for the humidity controller 8 as needed (during cooling in summer, the relative humidity should be 40%-80%; during heating in winter, it should be controlled at 30%-60%; the indoor temperature suitable for the elderly and children is 45%-50%; the most suitable indoor temperature for patients with respiratory diseases such as asthma is between 40%-50%). When the humidity sensor 10 detects that the actual humidity in the room is close to or exceeds the set value, the ventilation fan motor 7 starts, and the exhaust fan starts to exhaust until the humidity sensor 10 detects that the room humidity has reached the set value.

[0016] It has built-in circuit overload protection to prevent fire in the event of a short circuit. The noise level is between 15dBA-30dBA, and the exhaust noise is low during operation.
