Description

Technical Field

[0001] This utility model belongs to the field of air purification and fresh air equipment, and relates to a fresh air equipment with controllable air humidity. Background Technology

[0002] A fresh air system is an independent air handling system consisting of a supply air system and an exhaust air system. It achieves indoor and outdoor air exchange through components such as purification devices, fans, ducts, and air vents. Existing fresh air systems and humidification systems are generally set up independently, thus requiring additional energy to drive the humidification system. Over long-term use, this undoubtedly increases energy consumption. However, the purified air from the fresh air system possesses a certain amount of kinetic energy. How to utilize this kinetic energy to reduce the external energy required for the humidification system is the main problem addressed by this patent.

[0003] Therefore, this utility model provides a fresh air device with controllable air humidity to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a fresh air device with controllable air humidity. The technical solution adopted is as follows: it includes a fresh air unit body, with an indoor air inlet pipe and an indoor air exhaust pipe fixedly installed on the front and rear sides of the left end of the fresh air unit body, respectively. The left end of the indoor air inlet pipe is fixedly connected to one end of a humidification pipe through a flange. An mounting plate is fixedly installed on the upper rear side of the humidification pipe. A drive fan blade assembly is rotatably installed at the rear middle position inside the humidification pipe. The drive fan blade assembly includes components that match the inner wall of the humidification pipe. The fan blades are arranged in an arc shape and fixedly mounted on a rotating shaft. The lower end of the rotating shaft is inserted into the lower inner wall of the humidification pipe. The upper end of the rotating shaft passes through the humidification pipe and the mounting plate in sequence. The upper end of the rotating shaft is fixedly connected to the turbine of the centrifugal fan. The right end of the side exhaust pipe of the centrifugal fan is fixedly connected to the air inlet pipe. The left end of the air inlet pipe is connected to the top left side of the humidification pipe. The top center air inlet pipe of the centrifugal fan is connected to the ultrasonic humidifier atomizing exhaust pipe installed on the left side of the mounting plate through the suction pipe.

[0005] As a preferred embodiment of this utility model, the end of the humidification pipe connected to the indoor air inlet pipe is a funnel shape that gradually narrows to the left; this design can increase the flow velocity of the purified air flowing through the humidification pipe, thereby increasing its power to drive the fan blade assembly.

[0006] As a preferred embodiment of this utility model, the blades of the centrifugal fan are made of carbon fiber and the surface of the blades is coated with a hydrophobic coating; this design reduces the weight of the centrifugal fan blades and reduces the efficiency reduction caused by water mist adhesion.

[0007] As a preferred embodiment of this utility model, a one-way solenoid valve is installed on the air intake pipe; by using a one-way solenoid valve, it is opened only when the speed of the centrifugal fan reaches a set threshold, thus avoiding water mist backflow during low-speed operation.

[0008] As a preferred embodiment of this utility model, the outer periphery of the intake pipe is wrapped with an electric heating film; by using an electric heating film, condensation inside the intake pipe is avoided, which would affect the exhaust efficiency.

[0009] As a preferred embodiment of this utility model, a liquid level sensor is installed on the top of the housing of the ultrasonic humidifier, and a water pump is installed on the rear side wall of the housing of the ultrasonic humidifier; by using the liquid level sensor to monitor the water level, the water pump is controlled to automatically add water.

[0010] The beneficial effects of this utility model are as follows: By setting up a horn-shaped humidification pipe, and installing a drive fan blade assembly inside the humidification pipe, the arc-shaped fan blades drive the rotating shaft to rotate under the drive of purified air. The rotation of the rotating shaft drives the centrifugal fan at the top to rotate. The centrifugal fan generates negative pressure, which discharges the atomized water vapor generated by the ultrasonic generator into the indoor air intake pipe of the fresh air unit through the air intake pipe. The purified air is humidified at the source, eliminating the need for additional energy for the humidification function, improving the wind energy utilization rate of the fresh air equipment, and reducing the overall energy consumption of the system.

Detailed Implementation

[0015] Example 1

[0016] like Figures 1 to 3As shown, the present invention discloses a fresh air device with controllable air humidity. The technical solution includes a fresh air unit body 1. An indoor air inlet pipe 11 and an indoor exhaust pipe 12 are fixedly installed on the front and rear sides of the left end of the fresh air unit body 1, respectively. The fresh air unit body 1 has a built-in control system, which integrates temperature and humidity sensors. The left end of the indoor air inlet pipe 11 is fixedly connected to one end of a humidification pipe 2 via a flange. The end of the humidification pipe 2 connected to the indoor air inlet pipe 11 has a flared shape that gradually narrows to the left. An mounting plate 21 is fixedly installed on the upper rear side of the humidification pipe 2 via a connecting column. A drive fan blade assembly 3 is rotatably installed in the rear middle position inside the humidification pipe 2. The drive fan blade assembly 3 includes arc-shaped fan blades 31 that match the inner wall of the humidification pipe 2. The arc-shaped fan blades 31 are circumferentially arrayed and fixedly mounted on a rotating shaft 32. The lower end is inserted into the lower inner wall of the humidification pipe 2. The upper end of the rotating shaft 32 passes through the humidification pipe 2 and the mounting plate 21 in sequence. The upper end of the rotating shaft 32 is fixedly connected to the turbine of the centrifugal fan 4. The blades of the centrifugal fan 4 are made of carbon fiber and have a hydrophobic coating on their surface. The side exhaust pipe of the centrifugal fan 4 is fixedly connected to the right end of the air inlet pipe 41. The left end of the air inlet pipe 41 is connected to the top left side of the humidification pipe 2. The top center air inlet pipe of the centrifugal fan 4 is connected to the atomizing exhaust pipe of the ultrasonic humidifier 5 installed on the left end of the mounting plate 21 through the suction pipe 42. A one-way solenoid valve 43 is installed on the air inlet pipe 41. An electric heating film 44 is wrapped around the outside of the suction pipe 42. A liquid level sensor 51 is installed on the top of the housing of the ultrasonic humidifier 5. A water pump 52 is installed on the rear side wall of the housing of the ultrasonic humidifier 5.

[0017] The working principle of this utility model is as follows: When the device is powered on, the purified air of the fresh air unit 1 is pressurized and discharged into the humidification pipe 2 through the indoor air inlet pipe 11. When the purified air flows over the arc-shaped fan blades 31, it drives the arc-shaped fan blades 31 to rotate. The arc-shaped fan blades 31 drive the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the blades of the centrifugal fan 4 at the top to rotate. When the rotation of the blades of the centrifugal fan 4 reaches a certain speed, the one-way solenoid valve 43 is opened by the control system. The negative pressure is generated in the casing of the centrifugal fan 4, which draws the atomized water vapor generated by the ultrasonic humidifier 5 into the air inlet pipe 41 through the air intake pipe 42, and then discharges it into the humidification pipe 2 through the air inlet pipe 41, thereby humidifying the purified air at the source. The humidified purified air is distributed in the room with the circulation of the fresh air system. The indoor conditions are monitored by the temperature and humidity sensor, and the control system controls the power of the ultrasonic humidifier 5, thereby controlling the amount of atomized water vapor generated by the ultrasonic humidifier 5, and thus regulating the humidity of the indoor air.
