Description

Technical Field

[0001] This invention relates to the field of central air conditioning vents, specifically a central air conditioning vent device. Background Technology

[0002] A central air conditioning unit's air outlet includes a ventilation duct and a frame plate at one end of the duct. When the central air conditioning outlet is installed on a building wall, the ventilation duct of the outlet is inserted into a window opening in the wall, and the frame plate is flush against the perimeter of the window opening facing the interior. During operation, the cold air generated by the central air conditioning unit flows into the room through the outlet. Because the cold air is at a low temperature, the temperature of the outlet frame plate decreases as the air passes through the outlet. If the indoor air is humid, moisture in the air easily condenses on the frame plate, forming condensation. This condensation flows down the frame edge onto the building wall, potentially causing damage. Furthermore, in enclosed spaces where maintaining internal humidity is crucial, if condensation forms on the central air conditioning outlet frame plate, it will not only damage the wall but also decrease the humidity level in the space. Summary of the Invention

[0003] This invention provides a central air conditioning vent device to solve the problem of condensation damaging the wall surface caused by the air vents of existing central air conditioning systems.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A central air conditioning outlet device includes a ventilation duct, one end of which is connected to a frame plate, and the inside of the frame plate is connected to the inside of the ventilation duct. The device is characterized in that the bottom edge of the frame plate is bent to form a water receiving groove, both ends of the water receiving groove are closed, and the bottom of the water receiving groove is connected to multiple pipes. One end of each pipe is connected to the inside of the water receiving groove, and the other end of each pipe is connected to the outside of the water receiving groove. Each pipe is equipped with an ultrasonic atomizing plate.

[0005] Furthermore, the bottom of the water receiving tank is connected to multiple pipes, one end of which is connected to the inside of the water receiving tank and the other end is connected to the outside of the water receiving tank. Each pipe is equipped with an ultrasonic atomizing plate.

[0006] Furthermore, a liquid level sensor is installed inside the water receiving tank.

[0007] Furthermore, the bottom of the water receiving trough is high in the middle and low at both ends.

[0008] Furthermore, the top edge of the frame plate is bent to form a curved edge.

[0009] In this invention, the bottom edge of the frame plate of the central air conditioning outlet is bent to form a water collection groove. When condensation forms on the frame plate, the condensation flows into the water collection groove under the action of gravity and is collected by the water collection groove, thereby preventing the condensation from flowing to the wall.

[0010] Furthermore, in this invention, an ultrasonic atomizing plate is installed in the pipe at the bottom of the water receiving tank. The ultrasonic atomizing plate turns the water in the receiving tank into mist and sprays it into the room through the pipe. Thus, when used in enclosed spaces, the condensation can be used to increase the humidity of the air in the enclosed space.

[0011] Compared with existing technologies, the present invention can prevent the condensate generated from flowing directly onto the building's vertical walls, and can utilize the condensate to form mist to increase the humidity of indoor air. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of an embodiment of the present invention. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and examples.

[0014] like Figure 1 As shown, this embodiment discloses a central air conditioning outlet device, which is installed on a vertical wall. This embodiment includes a ventilation duct 1, with openings at both the front and rear ends of the ventilation duct 1. The front opening of the ventilation duct 1 is connected to a frame plate 2, and the space inside the frame plate 2 is connected to the front opening of the ventilation duct 1.

[0015] The bottom edge of the frame plate 2 bends forward and downward and then forward and upward to form a curved section. Side plates are installed at the left and right ends of the curved section. The space inside the curved section is closed at the left and right ends by the two side plates. The curved section and the side plates at the left and right ends form a water receiving trough 3, with the curved section serving as the bottom of the water receiving trough 3.

[0016] During installation, the ventilation duct 1 is inserted into the window opening in the wall, with the rear frame of the frame plate 2 flush against the wall surrounding the window opening, and the front frame of the frame plate 2 facing inwards. Cool air from the central air conditioning system enters the ventilation duct through the rear opening of the ventilation duct 1, then passes through the front opening of the ventilation duct 1 and the space within the frame of the frame plate 2 before being blown into the room. When condensation occurs on the front edge of the frame plate 2 facing inwards, the condensate slides down into the water collection trough 3 under gravity and is collected there, thus preventing the condensate from flowing onto the building wall below the frame plate 2.

[0017] As an improvement to this embodiment, multiple pipes 4 are connected to the bottom of the water receiving tank 3. One end of each pipe 4 is connected to the inside of the water receiving tank 3, and the other end of each pipe 4 faces the lower front of the frame to lead to the room. Each pipe 4 is equipped with an ultrasonic atomizing plate 5, which isolates the pipe 4. An external controller is electrically connected to the ultrasonic atomizing plate 5 via a connecting wire.

[0018] When a certain amount of water accumulates in the water tank 3, the water enters the pipe 4. At this time, the external controller controls the ultrasonic atomizing plate 5 to work, causing the water in the pipe 4 to form a mist, which is then sprayed out from the pipe 4 towards the indoor opening. Therefore, when this embodiment is applied to an enclosed space where maintaining air humidity is required, condensation can be used to form a mist that is sprayed into the enclosed space. In this case, not only can condensation be prevented from flowing directly onto the building's walls, but the condensation can also be used to form a mist to maintain the air humidity in the enclosed space.

[0019] Furthermore, the bottom of the water receiving tank 3 is shaped with a higher center and lower left and right ends. This design allows condensate falling into the tank to concentrate at the lowest points (left and right ends) to maintain a certain liquid level. Pipe 4 is connected to the bottom of the water receiving tank 3 near the left and right ends, ensuring sufficient water for mist formation within the pipe 4.

[0020] Liquid level sensors are installed near the left and right ends of the water receiving tank 3. These sensors are electrically connected to the controller that controls the external ultrasonic atomizing plate 5. The liquid level sensors collect the liquid level signal at their location and transmit it to the external controller. The external controller compares the liquid level with a set threshold. When the collected liquid level is greater than or equal to the set threshold, the external controller controls the ultrasonic atomizing plate 5 to operate and form mist.

[0021] As an improvement to this embodiment, the top edge of the frame plate 2 bends forward and upward to form a curved edge 6. The horizontal distance between the farthest point of the curved edge 6 and the front side surface of the frame plate 2 is smaller than the horizontal distance between the farthest point of the water collection trough 3 and the front side surface of the frame plate 2, so that the downward projection of the curved edge 6 can fall completely into the water collection trough 3. Through the above structural design, it can be ensured that the condensate droplets formed on the top edge of the frame plate 2 fall into the receiving trough 3 and are collected, further preventing condensate from flowing directly onto the building's vertical wall surface.
