Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to an anti-drip device for air conditioning vents. Background Technology

[0002] Water dripping from air conditioner vents is a common problem during air conditioner use, especially in high humidity environments. Because the surface temperature of the air vent is lower than the dew point temperature of the indoor air, water vapor in the air condenses on the surface of the air vent, eventually forming a dripping phenomenon.

[0003] Existing technologies primarily employ several methods to prevent water dripping from air conditioner vents, but each method has its limitations: First, adjusting the air conditioner's operating mode can reduce condensation. In humid seasons, users can first turn on the dehumidification mode to lower indoor humidity, then switch to cooling mode, or gradually lower the temperature to slowly reduce condensation at the vent. However, this method is complex, requiring manual adjustment based on environmental changes and relying on human intervention, making automatic control difficult. Second, selecting vent materials less prone to condensation can alleviate dripping. For example, engineering plastic panels can replace traditional metal panels because plastics have lower thermal conductivity, slowing down cold air transfer and reducing temperature differences on the vent surface, thus decreasing condensation. However, this method... The first method can only alleviate condensation, but cannot fundamentally solve the problem of the air vent surface temperature being lower than the dew point temperature. In practical applications, although engineering plastic panels are slightly better than metal panels, it is still difficult to completely avoid dripping in high humidity environments. The second method is to reduce condensation by adjusting the air speed and direction. For example, increasing the air conditioner's fan speed can allow the cold air to spread quickly and prevent the local temperature of the air vent from being too low, or adjusting the direction of the air guide plate can prevent the cold air from blowing directly onto the air vent surface. However, this method also requires manual intervention, and in high humidity environments, adjusting the air speed and direction is difficult to completely prevent condensation. In actual use, users often find it difficult to find the best adjustment method, resulting in the dripping problem still existing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an anti-drip device for air conditioning vents. This device is designed to be simple in structure, precise in control, and capable of automatically adjusting the vent temperature to ensure that the vent temperature is always higher than the air dew point temperature, thereby effectively preventing dripping.

[0005] The technical solution adopted by this invention to solve its technical problem is: An anti-drip device for an air conditioner vent includes an vent body with a cavity, one end of which has an air inlet and an air outlet; a waste heat collection unit installed at the outdoor cooling fan of the air conditioner to collect the hot air exhausted by the cooling fan; an air supply unit connected at one end to the waste heat collection unit and at the other end to the air inlet of the cavity to deliver the hot air exhausted by the outdoor cooling fan into the cavity; a temperature detection unit installed on the surface of the vent body to monitor the surface temperature of the vent body in real time; and a controller connected to both the air supply unit and the temperature detection unit to control the airflow of the air supply unit based on the surface temperature of the vent body.

[0006] Compared with the prior art, the beneficial effects of the present invention are: The core of this invention lies in its ingenious use of the hot air exhausted by the outdoor unit fan of the air conditioner as a continuous and stable heat source. Unlike traditional anti-drip solutions, this design does not require additional auxiliary heating devices such as electric heating rods or heating wires, thus achieving significant energy-saving effects and completely eliminating the safety hazards caused by auxiliary heating elements. This invention uses a temperature detection unit on the surface of the air outlet body to monitor the surface temperature of the air outlet body in real time with high precision. The controller then sends air into the cavity. This intelligent closed-loop regulation mechanism ensures that the temperature of the air outlet body is always maintained at a level higher than the current ambient air condensation temperature, thereby completely destroying the physical conditions for condensation at the source and fundamentally preventing dripping.

[0007] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the air outlet body includes a metal frame and a grille placed inside the metal frame, and the interior of the metal frame is provided with a cavity.

[0008] Preferably, the cavity is provided with multiple partitions, with adjacent partitions staggered, and the gap between the partitions and the inner wall of the metal frame forms an air passage.

[0009] Preferably, the waste heat collection unit includes an air collecting hood, which is placed on the air outlet side of the outdoor cooling fan of the air conditioner. An air outlet is provided on the air collecting hood, and a filter screen is provided inside the air outlet.

[0010] Preferably, the air supply unit includes an induced draft fan, the air inlet of which is connected to the air outlet of the air collection hood, and the air outlet of which is connected to the air inlet of the cavity through a pipe; the induced draft fan is connected to a controller.

[0011] Preferably, the temperature detection unit is a temperature sensor. The controller compares the temperature of the air outlet surface fed back by the temperature sensor with a preset condensation temperature threshold. When the temperature of the air outlet surface is lower than the threshold, the air supply unit is activated to send hot air into the cavity. When the temperature of the air outlet surface is higher than the threshold, the air supply unit stops supplying air. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0014] like Figures 1 to 3 As shown, an air conditioner vent anti-drip device includes an vent body 1, a waste heat collection unit, an air supply unit, a temperature detection unit, and a controller.

[0015] The air outlet body 1 is composed of a metal frame 101 and a grille 102 placed in the inner circle of the metal frame 101. The interior of the metal frame 101 is provided with a cavity 103. One end of the cavity 103 is provided with an air inlet 104 and the other end is provided with an air outlet 105.

[0016] The cavity 103 is internally provided with several partitions 106, with adjacent partitions 106 staggered. The gap between the partitions 106 and the inner wall of the metal frame 101 forms an air passage. Adding partitions 106 can improve the reversal of hot air within the cavity 103, slow down the hot air flow rate, and thus increase the residence time of hot air within the cavity 103.

[0017] The waste heat collection unit is installed at the outdoor cooling fan 3 of the air conditioner to collect the hot air discharged by the cooling fan. Specifically, the waste heat collection unit is a fan hood 2, which is installed on the air outlet side of the outdoor cooling fan 3 of the air conditioner. The fan hood 2 is provided with an air outlet, and a filter screen is provided inside the air outlet to remove dust and other debris.

[0018] One end of the air supply unit is connected to the waste heat collection unit, and the other end is connected to the air inlet 104 of the cavity 103. It is used to transport the hot air discharged by the outdoor cooling fan 3 of the air conditioner to the cavity 103 through the air inlet 104. Specifically, the air supply unit is an exhaust fan 4. The air inlet of the exhaust fan 4 is connected to the air outlet of the air collector hood 2, and the air outlet is connected to the air inlet 104 of the cavity 103 through a pipe. The exhaust fan 4 transports the hot air discharged by the outdoor cooling fan 3 of the air conditioner to the cavity 103.

[0019] The temperature detection unit is a temperature sensor, which is installed on the surface of the metal frame 101 to monitor the temperature of the surface of the metal frame 101 in real time.

[0020] The induced draft fan 4 and the temperature sensor are electrically connected to the controller. The controller compares the temperature of the metal ore surface fed back by the temperature sensor with the preset condensation temperature threshold. When the surface temperature of the metal frame 101 is lower than the condensation temperature threshold, the induced draft fan 4 is started to send hot air into the cavity 103 until the surface temperature of the metal frame 101 is higher than the condensation temperature threshold, at which point the induced draft fan 4 stops sending air.

[0021] This invention utilizes the hot air exhausted from the outdoor fan of an air conditioner as a heat source, eliminating the need for additional heating equipment. The temperature detection unit monitors the temperature of the air outlet body in real time and automatically adjusts the air supply to ensure that the temperature of the air outlet body is always higher than the condensation temperature, thus fundamentally preventing water dripping. This device has a simple structure, is easy to install and maintain, and has a wide range of applications.

[0022] In addition, the device has a compact and sophisticated structure, and each functional module (such as temperature sensor, controller, induced draft fan, etc.) can be modularly installed. It is suitable for supporting new air conditioning systems and also facilitates low-cost retrofitting of existing air conditioning systems. Its maintenance requirements are extremely low, requiring only periodic cleaning of the filter and sensor.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
