Description

Technical Field

[0001] The utility model relates to a central air-conditioning unit, in particular to an air-conditioning water cut-off device with a wind speed regulating function. Background Art

[0002] Central air conditioning units need to control the temperature and humidity of the gas. A heat exchanger will be placed inside. The heat exchanger will produce condensed water when working. When the temperature difference between the gas and the heat exchanger is too large or the humidity of the gas is too high, there will be too much condensed water accumulation and low drainage efficiency, and even the condensed water will be blown up with the airflow. The heat exchange efficiency of the gas is also related to the speed at which the gas passes through the heat exchanger. In order to solve the problem of condensed water being blown up with the airflow, the traditional approach is: first, increase the length of the water pan to cover as much as possible the places where water droplets will condense and drip; second, control the gas flow rate, but this will increase costs or reduce heat exchange efficiency.

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0017] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0018] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0019] Reference Figure 1-4, an air-conditioning water-cutting device with a wind speed adjustment function comprises a cabinet, wherein a heat exchanger 1 is installed in the cabinet, and an outer bracket 2 is installed on the air outlet side of the heat exchanger 1, and a plurality of first rotating plates 3 are installed on the side of the outer bracket 2 close to the heat exchanger 1 and rotated from bottom to top, and a first channel 5 is formed between adjacent first rotating plates 3; a plurality of second rotating plates 4 are installed on the side of the outer bracket 2 away from the heat exchanger 1 and rotated from bottom to top, and a second channel 6 is formed between adjacent second rotating plates 4, and the first channel 5 is connected with the second channel 6 to form an air duct, and the rotation center of the first rotating plate 3 is close to one end of the second rotating plate 4, and the rotation center of the second rotating plate 4 is away from one end of the first rotating plate 3. By rotating the first rotating plate, the wind speed is adjusted to improve the heat exchange efficiency, and by rotating the second rotating plate, the air duct is made more tortuous and the water-cutting ability is improved. The two cooperate with each other to improve the water-cutting ability under the premise of ensuring the heat exchange efficiency.

[0020] The first rotating piece 3 is driven by a first motor, and the first motor is electrically connected to a first sensor. The second rotating piece 4 is driven by a second motor, and the second motor is electrically connected to a second sensor.

[0021] The first rotating piece 3 and the second rotating piece 4 are both bent parts.

[0022] The bottom of the cabinet is provided with a water collecting pan 7 tilted to one side, and a support beam 8 tilted in the opposite direction to the water collecting pan 7 is installed in the water collecting pan 7, and the top surface of the support beam 8 is horizontal. The heat exchanger 1 and the outer bracket 2 are installed on the support beam 8, and the opposite tilting can keep the heat exchanger 1 in a horizontal state, so as to avoid the heat exchange medium flowing inside due to the tilt of the heat exchanger 1, and then avoid the heat exchange efficiency of the heat exchanger 1 being affected. A drain pipe 9 is provided at the lowest end of the water collecting pan 7. Through this design, the water in the water collecting pan 7 can flow quickly to the drain pipe 9, effectively solving the problem of low drainage efficiency due to excessive accumulation of condensed water. In addition, the support beam 8 is suspended in the water collecting pan 7, which can isolate the heat exchanger 1 from the condensed water, and can avoid the problem of condensed water accumulating and not being able to be discharged due to the adsorption of condensed water on the bottom of the heat exchanger 1 due to tension, and at the same time reduce the corrosion caused by water immersion, and increase the life of the heat exchanger 1.

[0023] When the second sensor detects condensed droplets in the airflow at the rear end of the cabinet, the second rotating plate 4 is controlled to make the connection between the first channel 5 and the second channel 6 more tortuous (such as Figure 3As shown in A in the figure, the density of water droplets is greater than that of air. Therefore, when water droplets follow the airflow to turn, inertia causes a significant increase in the chance of hitting the wall, making it more capable of intercepting water droplets. After being intercepted, the water droplets will flow into the water collection tray, thereby effectively intercepting the water droplets, controlling the length of the water collection tray 7, and reducing the space and material costs of the unit.

[0024] When the heat exchange efficiency decreases, the first sensor controls the first rotating plate 3 to rotate so that the inlet area of ​​the first channel 5 decreases (e.g. Figure 4 As shown in B in the figure), since the flow rate of the air flow inside the unit is fixed (without changing the speed of the wind cabinet motor), the wind speed at the inlet of the first channel 5 is increased, thereby increasing the overall wind speed and achieving heat exchange efficiency adjustment within a certain range.

[0025] The first sensor, the second sensor, the first motor and the second motor are all electronic accessories available on the market.
