Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, and more specifically, to a double-process condensation and dehumidification fresh air fan. Background Art

[0002] The fresh air air-conditioning unit mainly includes a box body, in which an air inlet section, a surface cooling section, a fan mixing section, a heating and humidifying section and an air outlet section are arranged from left to right. When the existing fresh air air-conditioning unit is in use, a filter plate is set at the air outlet section, that is, the end of the box body, to filter the airflow during the circulation of the airflow, and air guide devices are set at both ends of the fan section. Therefore, the airflow blown out from the fan section has a relatively high intensity and is too concentrated. During long-term operation, the filter plate will be subjected to a greater impact, and there are problems such as short service life, the filtering position of the filter plate is concentrated in one area, and the filtering effect is not ideal.

[0003] After searching, the Chinese patent with publication number CN219389906U discloses a condensation heat recovery dehumidification fresh air air conditioning unit. The difference between this device and the traditional fresh air air conditioning unit is that filter plates are provided in the mixing chamber and the air supply chamber, which can perform multiple filtrations on the airflow. A fan is installed in the fan chamber, which can draw the external airflow into the chassis for circulation. During the flow process, the conical hood installed at the fan port will guide the airflow and concentrate the airflow together, thereby reducing the airflow loss.

[0004] However, when this structure is actually used, since no protective measures are installed inside the air outlet of the device, the dust in the air is only blocked by the filter plate inside the body, but it cannot prevent objects from entering the body through the air outlet, which causes large objects to fall into the body and cannot be discharged, which is not conducive to the use of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a dual-flow condensation and dehumidification fresh air fan to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a dual-process condensing and dehumidifying fresh air fan, comprising a body, an air inlet bin is provided at one end of the body, an air outlet bin is provided on the other side of the body, an air inlet duct is provided on the top of the air inlet bin, an air inlet is provided at one end of the air inlet bin, an air outlet is provided on one side of the air outlet bin, and a protective component is provided inside the air outlet.

[0007] Preferably, the protective component includes an air outlet duct, which is arranged on the outside of the air outlet, and an inclined panel is provided on the top of the air outlet duct, which is fixedly connected to the top of the air outlet duct, and a rotating shaft is provided on the inner wall of the air outlet duct, and a protective plate is provided on the outside of the rotating shaft, which is fixedly connected to the rotating shaft, one end of the rotating shaft passes through the air outlet duct, and a motor is provided on the outside of the air outlet duct, and a rotating gear is provided at the output end of the motor and one end of the rotating shaft, and the rotating gear is in a meshing state.

[0008] Through the above scheme, it can be seen that an air outlet duct is arranged on the outside of the air outlet at one end of the body, and a rotating shaft is installed on the inner wall of the air outlet duct, and then the protective plate is installed on the outside of the rotating shaft. By starting the motor on the outside of the air outlet duct, the motor drives the rotating gear installed at its output end to rotate and then drives the rotating gears on both sides to rotate synchronously, thereby realizing the open and closed state of the air outlet duct, preventing foreign objects from entering the body and causing damage to the inside of the body, and improving the practicability of the device.

[0009] Preferably, a connecting groove is provided on the surface of the air inlet duct, an adapter slot is provided on the top of the air inlet duct, a protective net is provided inside the adapter slot, the protective net and the adapter slot are clamped with each other, a threaded groove is provided on the surface of the protective net, the protective net is threadedly connected to the air inlet duct, a fan is provided inside the body, a triangular slope is provided on one side of the fan, the number of the triangular slopes is set to two, a guide plate is provided on one side of the fan, the number of the guide plates is set to two, an arc plate is provided on the outer side of the triangular slope, ventilation slots are provided on the surface of the arc plate, the number of the ventilation slots is set to multiple, both ends of the arc plate are fixedly connected to the outer side surface of the triangular slope, a transverse guardrail is provided inside the air inlet, a longitudinal guardrail is provided on one side of the transverse guardrail, and the outer sides of the transverse guardrail and the longitudinal guardrail are respectively fixedly connected to the inner wall surface of the air inlet.

[0010] Through the above scheme, it can be seen that a guide plate is arranged at the air outlet of the fan to prevent the wind blown out by the fan from partially flowing back when touching the curved plate, thereby causing internal damage to the fan after long-term use. The wind blown out by the fan is gathered together by the guide plate, and the air outlet is also narrowed. When the warm air touches the curved plate, part of the warm air will pass through the connecting groove on the surface of the curved plate and be discharged to the outside. At the same time, part of the warm air will be blocked by the curved plate from flowing back, but due to the obstruction of the guide plate, it cannot re-enter the interior of the fan, thereby improving the practicability of the device.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting a protective component, compared with the prior art, an air outlet duct is set on the outside of the air outlet at one end of the body, and a rotating shaft is installed on the inner wall of the air outlet duct, and then the protective plate is installed on the outside of the rotating shaft. By starting the motor on the outside of the air outlet duct, the motor drives the rotating gear installed at its output end to rotate, and then drives the rotating gears on both sides to rotate synchronously, so as to realize the open and closed state of the air outlet duct, prevent foreign objects from entering the body and causing damage to the inside of the body, and improve the practicality of the device;

[0013] 2. By setting a guide plate, compared with the prior art, a guide plate is set at the air outlet of the fan, so as to prevent the wind blown out of the fan from partially flowing back when touching the curved plate, thereby causing internal damage to the fan after long-term use. The wind blown out of the fan is gathered together by the guide plate, and the air outlet is also narrowed. Then, when the warm air touches the curved plate, part of the warm air will pass through the connecting groove on the surface of the curved plate and be discharged to the outside. At the same time, part of the warm air will be blocked by the curved plate from flowing back, but due to the obstruction of the guide plate, it cannot re-enter the interior of the fan, thereby improving the practicability of the device.
