Dehumidification Wheel Replacement Device for Rotary Dehumidifier

technical field

The invention relates to a dehumidification wheel replacement device, in particular to a dehumidification wheel replacement device for a rotary dehumidifier which can achieve fixing and rotation functions and allows users to replace the dehumidification wheel by themselves.

Background technique

In recent years, the sales of drip-type household dehumidifiers with dehumidification wheels as dehumidification components have gradually replaced the existing compressor-type dehumidifiers. Generally, the rotary dehumidifier with the dehumidification wheel as the dehumidification component is used. Its structural principle is shown in Figure 1. The high-humidity air A1 in the room enters the dehumidification side A2 of the dehumidification wheel A3 through the condenser A9, and the moisture in the air is dehumidified. suction, and then the dry air A5 is pumped by the dehumidification fan A4 to complete the dehumidification function of the air. The dehumidification wheel A3 takes the area after absorbing moisture to the regeneration side A7 through the transmission mechanism for thermal drying and desorption of moisture. At the beginning of the circuit is a regenerative heater A8, which heats the gas in the pipeline, allowing the high-heat gas for regeneration to flow through the dehumidification wheel A3 to desorb the moisture in it, forming hot and humid air A6, which is A6 enters the condenser A9 to condense water through the guidance of the pipeline. The condensed water is guided by the pipeline in the condenser A9, and then flows into the water container A11 at the bottom of the dehumidification device for water collection, and the gas flow in this regeneration area is powered by the regeneration fan A10. , so the process can achieve the function of dehumidification.

Generally, the dehumidification wheel in this kind of dehumidification device is fixed in the center of the dehumidification device with an axial support to fix the dehumidification wheel, and then use the peripheral transmission mechanism B2 to rotate the dehumidification wheel B1, as shown in Figure 2, to achieve dehumidification. with regeneration function. The commonly used transmission methods can be roughly divided into three types, including gear direct transmission type, pulley driven type, and shaft center direct transmission type. The gear direct transmission type is to use the gear on the transmission mechanism B2 to match the tooth shape on the dehumidification wheel B1 protection frame, thereby driving the dehumidification wheel B1 to rotate, as shown in Figure 2; the pulley drive type is the dehumidification wheel B1 protection frame. There are multiple toothed parts , and there is a toothed driving pulley B4 on the transmission mechanism, which is connected by a transmission belt B3 to achieve the transmission function, as shown in Figure 3; as shown in Figure 4, the direct transmission of the shaft center will The axis of the dehumidification wheel B1 is set between the transmission motor B5, and a coupling B6 connects the two, so that the power can be transmitted to the dehumidification wheel B1 to drive the dehumidification wheel B1 to rotate.

The dehumidifier wheel of the above-mentioned dehumidifier generally has a service life of about 8 to 10 years, but due to the influence of environmental factors, such as dust (dust), smoke particles (cigarettes), etc., will block the moisture absorption holes in the dehumidifier wheel, so the dehumidifier is often used. Life expectancy is much lower than normal. However, for a dehumidifier that has lost its function, the original dehumidification function of the dehumidifier can only be restored by replacing the new dehumidification wheel assembly. The replacement of the dehumidification wheel is quite inconvenient, and the unit needs to be disassembled to replace the dehumidification wheel.
