Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a fresh air ventilator with a dust removal function. Background Art

[0002] A fresh air ventilator is an environmental protection and energy-saving device used to improve indoor air quality and recover the energy of air-conditioning exhaust air. Its main components are a housing, a heat exchange core, and a filtering device. The traditional filtering device is composed of a simple superposition of several layers of filter screens, with poor filtering accuracy, unable to filter tiny dust, and limited in improving air quality. Later, people used the principle of electrostatic dust collection to adsorb tiny particles, improving air quality, and a fresh air ventilator with a dust removal function is one type of fresh air ventilator.

[0003] The Chinese patent with the patent number CN201811594321.3 discloses a fresh air ventilator, which includes a housing, a top plate, a heat exchange core, a blower, and an exhaust fan; the top plate covers the opening at the top of the housing, and a fresh air duct and a dirty air duct are arranged separately inside the housing; the housing is provided with a fresh air inlet and a fresh air outlet, the fresh air inlet and the fresh air outlet are connected through the fresh air duct, and the blower is arranged close to the fresh air outlet; the housing is provided with a dirty air inlet and a dirty air outlet, the dirty air inlet and the dirty air outlet are connected through the dirty air duct, and the exhaust fan is arranged close to the dirty air outlet; an installation rib for installing the heat exchange core is arranged inside the housing.

[0004] Although the installation space formed by the installation rib of the fresh air ventilator described in the above patent is larger than the contour size of the heat exchange core, thus forming an installation gap, making it convenient to insert and install the heat exchange core into the housing, in the long-term use of the existing fresh air ventilator with a dust removal function, a large amount of dust and large particle impurities floating in the air will adhere to the surface of the filter screen. In order to ensure the air exchange quality and air exchange rate of the fresh air ventilator, users need to frequently clean the surface of the filter screen inside the fresh air ventilator, making the device inconvenient in daily use. Summary of the Utility Model

After the cleaning is completed, the user pulls out the drawer by pulling the handle, and then the dust in the drawer can be centrally processed.

[0021] (III) Beneficial effects

[0022] The utility model has the following beneficial effects compared with the prior art:

[0023] To solve the problem that although the installation space formed by installing the convex ribs of the existing fresh air ventilator is larger than the contour size of the heat exchange core, an installation gap is formed in this way to facilitate the insertion and installation of the heat exchange core into the machine housing, but a large amount of dust and large particulate impurities floating in the air will adhere to the surface of the filter screen during the long-term use of the existing fresh air ventilator with dust removal function. In order to ensure the air exchange quality and air exchange rate of the fresh air ventilator, the user needs to frequently clean the surface of the filter screen in the fresh air ventilator, resulting in inconvenience in the daily use of the device. Through the design of the electric slide rail, slider, cleaning plate, dust collection box and handle, during the use of the device, when it is necessary to clean the dust and large particulate impurities on the surface of the first filter screen, the user controls the slider to move on the surface of the electric slide rail through the operation panel to drive the cleaning plate to move up and down, so that the cleaning plate can sweep the dust on the surface of the first filter screen into the drawer in the dust collection box. After the cleaning is completed, the user pulls out the drawer by pulling the handle, and then the dust in the drawer can be centrally processed, thus effectively improving the use convenience of the device.
