Description

Technical Field

[0001] This utility model relates to the field of building heating, ventilation and air conditioning technology, and more specifically, to a building heating, ventilation and air conditioning device. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is a component of buildings. In academic classification, it stands for Heating, Gas Supply, Ventilation, and Air Conditioning Engineering, encompassing heating, ventilation, and air conditioning. Functionally, it's an indispensable part of future homes, with ventilation systems being essential. Traditional ventilation systems often have filters and other components that are difficult to replace, leading to a decrease in purification capacity over time.

[0003] In existing building HVAC systems, the cleaning of filters is mostly achieved by modifying them into detachable structures. This means that the filter must be removed when cleaning is required. Although detachable filters are relatively easy to install and remove, the operation of installing and removing the filter is still necessary, which reduces the frequency of filter cleaning.

[0005] A building heating, ventilation, and air conditioning (HVAC) device includes a ventilation duct, a filter cover, and a cleaning mechanism. The filter cover is disposed within the ventilation duct and has a conical structure, with its narrow end near the air outlet of the ventilation duct. The cleaning mechanism is disposed on the side of the filter cover near the air inlet of the ventilation duct. The cleaning mechanism includes a rotating shaft, a first spiral cleaning plate, and a drive assembly. The rotating shaft is rotatably mounted within the ventilation duct and coaxially arranged with the filter cover. The first spiral cleaning plate is fixed to the outside of the rotating shaft and located within the filter cover. The first spiral cleaning plate has a variable-diameter spiral structure adapted to the filter cover, and first bristles are provided on the outside of the first spiral cleaning plate. The drive assembly drives the rotating shaft to rotate. A switchable drain outlet is provided at the bottom of the ventilation duct, located on the side of the filter cover near the air inlet.

A bearing is provided on the rotating shaft, and the bearing is located on the side of the first spiral cleaning plate near the air inlet. The bearing is fixedly connected to the ventilation duct by a fixing rod.

[0007] Furthermore, the cleaning mechanism also includes a second spiral cleaning plate, which is fixed to the outside of the rotating shaft and located on the side of the first spiral cleaning plate near the air inlet.

The second bristles are in contact with the inner wall of the ventilation duct, and the drain outlet is located on the side of the second spiral cleaning plate near the air inlet.

[0008] Furthermore, the drive assembly includes a motor, a first pulley, a second pulley, and a transmission belt. The motor is installed at the top inside the ventilation duct. The first pulley and the second pulley are fixedly connected to the motor and the rotating shaft, respectively. The transmission belt is drivenly connected to the first pulley and the second pulley.

[0009] Furthermore, a sewage discharge channel is fixed to the outside of the sewage outlet, and a sealing plate is slidably inserted in the middle of the sewage discharge channel.

[0010] Furthermore, the sewage discharge channel has a square tubular structure, with a through hole in the middle of the side of the sewage discharge channel, and sliding grooves on both sides of the through hole. Sliding strips adapted to the sliding grooves are provided on both sides of the sealing plate. The sealing plate is telescopically disposed in the through hole and is slidably connected to the sewage discharge channel through the sliding strips and sliding grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The building heating, ventilation and air conditioning device of this utility model uses a cone-shaped filter cover to replace the traditional filter screen, and a cleaning mechanism is set in the ventilation duct. The cleaning mechanism consists of a rotating shaft, a first spiral cleaning plate, and a drive assembly. The first spiral cleaning plate is set inside the filter cover and has a variable diameter spiral structure adapted to the filter cover.
