Technical Field

[0001] This utility model relates to the field of fresh air system technology, and specifically to an air outlet device for a fresh air system. Background Technology

[0002] A fresh air system uses specialized equipment to supply fresh air into a sealed room from one side and exhaust it to the outside from the other side, creating a "fresh air flow field" within the room. At the same time, corresponding air conditioning equipment is installed to regulate the temperature, thereby meeting the needs of indoor fresh air exchange and temperature regulation.

[0003] Existing fresh air systems typically have their air outlets installed on the roof to allow fresh air to diffuse throughout the room. However, such outlets have limited air outlet angles, making it impossible to provide fresh air to the room from all directions. Furthermore, their outlet height cannot be adjusted, failing to meet users' needs for adjustable outlet height. Utility Model Content

[0019] The following detailed explanation illustrates the specific implementation methods:

[0020] like Figures 1 to 3 As shown:

[0021] An air outlet device for a fresh air system includes a body 11, which is used to centrally mount other mechanisms. The body 11 has a cylindrical structure, with an air inlet 12 at the lower part and a plurality of air outlet slots 13 evenly distributed on the upper outer side wall of the body 11, so that air can be discharged from all four sides of the upper part of the body 11.

[0022] It also includes a control unit, a refrigeration module, and a regulating module. The refrigeration module and the regulating module are both installed inside the body 11. The refrigeration module is used to refrigerate the air, and the regulating module is used to seal the inside of the body 11, thereby controlling the conduction of each air outlet 13. The control unit is installed in the body 11 and is electrically connected to the refrigeration module and the regulating module. The control unit is used to control the operation of other electrical components.

[0023] The refrigeration module includes refrigerant pipes and an airflow mechanism. The refrigerant pipes are connected to the outdoor unit of the air conditioner in the fresh air system, enabling the outdoor unit to deliver refrigerant to the refrigerant pipes for cooling. The refrigerant pipes include a spiral pipe 21, several annular pipes 22, and a circulation pipe 24. The spiral pipe 21 is installed on the inner wall of the lower part of the body 11. The spiral pipe 21 can extend the flow path of the refrigerant and improve the cooling efficiency. One end of the spiral pipe 21 is connected to the outdoor unit of the air conditioner in the fresh air system. The annular pipes 22 are evenly arranged on the inner wall of the upper part of the body 11, and each annular pipe 22 is located below each air outlet slot 13. Each annular pipe 22 further cools the air inside the body 11. The annular pipes 22 are connected and connected to each other through several connecting pipes 23, so that the refrigerant can flow smoothly from the spiral pipe 21 into each annular pipe 22. The bottommost annular pipe 22 is connected and connected to one end of the circulation pipe 24. The other end of the circulation pipe 24 is connected to the outdoor unit of the air conditioner in the fresh air system. The circulation pipe 24 circulates the refrigerant back to the outdoor unit of the air conditioner.

[0024] The airflow mechanism includes a drive motor 25 and an impeller 26. The drive motor 25 is fixed inside the body 11 and is located inside the spiral tube 21. The impeller 26 is mounted on the output shaft of the drive motor 25. The drive motor 25 drives the impeller 26 to rotate and generate airflow. The outer side of the impeller 26 is separated from the inner side of the spiral tube 21, so the airflow generated by the impeller 26 can move upward.

[0025] The adjustment module includes a drive mechanism and a sealing mechanism. The drive mechanism includes an adjustment motor 32, a screw 33, and several guide rods 34. The adjustment motor 32 is fixedly installed inside the machine body 11 via a mounting bracket 31 and is located above the impeller 26. The output shaft of the adjustment motor 32 is connected to one end of the screw 33 via a coupling. The other end of the screw 33 is rotatably installed on the inner top wall of the machine body 11. The lifting plate 35 of the sealing mechanism is threadedly connected to the screw 33. The guide rods 34 are fixedly installed on the mounting bracket 31 and the machine body 11. Between the inner top walls of body 11, guide rod 34 and lifting plate 35 are slidably connected. Through the limiting and guiding effect of guide rod 34, lifting plate 35 can move up and down when screw 33 rotates. Several sealing gaskets 36 are evenly fitted on the outer wall of lifting plate 35. The sealing gaskets 36 are made of rubber or other materials with a certain elasticity. The sealing gaskets 36 abut against the inner side of annular pipe 22 and cut off the internal space of body 11, control the flow range of airflow in body 11, and thus adjust the air outlet height of body 11.

[0026] The control unit includes an operation panel 41 and a control host 42. The control host 42 is installed inside the body 11, and the operation panel 41 is installed on the surface of the body 11. The control host 42 is electrically connected to the operation panel 41, the drive motor 25, and the adjustment motor 32. The operation panel 41 is used to operate the device. Both the operation panel 41 and the control host 42 are existing mature technologies and will not be described in detail here. The control unit also includes a temperature sensor for detecting the temperature and transmitting the temperature data back to the control host 42.

[0027] A counterweight base 14 is installed at the bottom of the body 11, which can improve the stability of the device.

[0028] The air inlet 12 at the body 11 is connected to the fresh air duct of the fresh air system, so that fresh air can enter the body 11.

[0029] The specific implementation process is as follows:

[0030] Before using the air outlet device of this fresh air system, first connect the spiral pipe 21 and the circulation pipe 24 to the outdoor unit of the fresh air system, and connect the fresh air duct of the fresh air system to the air inlet 12 of the unit 11. Then you can start the fresh air system and this device. When the device is started, the outdoor unit of the fresh air system will input refrigerant into the refrigerant pipe, so that the refrigerant will circulate in the spiral pipe 21 and the annular pipe 22, thereby reducing the temperature inside the unit 11. At the same time, the drive motor 25 drives the impeller 26 to rotate, and fresh air enters into the unit 11 from the air inlet 12, forming an airflow inside the unit 11. The airflow is cooled by the refrigerant pipe, thereby generating a cold airflow. The cold airflow can then be discharged from the unit 11 from each air outlet slot 13, so that the unit 11 can ventilate in all directions.

[0031] By starting the regulating motor 32, the regulating motor 32 drives the screw 33 to rotate, and the screw 33 drives the lifting plate 35 to move up and down inside the body 11. The lifting plate 35 drives each sealing gasket 36 to move together. By moving the sealing gasket 36 to different height positions inside the body 11, the internal space of the body 11 is blocked, and the conduction of each air outlet slot 13 can be controlled, thereby adjusting the air outlet height of this device.

[0032] The air outlet device of this fresh air system is connected to the outdoor unit of the fresh air system air conditioner through a refrigerant pipe, so that the outdoor unit can deliver refrigerant to the refrigerant pipe for cooling. The airflow mechanism blows the air to introduce fresh air into the unit 11. After being conditioned by the refrigerant pipe, the fresh air is discharged from the air outlet slot 13. The air outlet slot 13 is evenly distributed on the outer wall of the unit 11, so that the fresh air can be discharged from all directions. At the same time, the air outlet height range of the fresh air can be adjusted by the adjustment module to meet the different usage needs of users.
