Description

Air Purifier {AIR PURIFIER}

The present invention relates to an air cleaner, and more particularly, to an air cleaner having an electrostatic precipitating filter.

In general, an air purifier is a device that filters dust and bacteria in the air to clean the air, and includes a blower fan that sucks and blows indoor air in the main body, which normally forms an exterior, and a filter that filters air pollutants such as dust. Therefore, the indoor air is allowed to flow through the filter by the blowing force generated by the blowing fan, so that the indoor air can be purified by the filter.

At this time, since the filter needs periodic cleaning due to its characteristics, the filter is moved to and detached from the main body so as to be easily separated from the main body.

The filter used in the air purifier includes an electrostatic precipitating electrostatic filter that collects pollutants in the air by electric power by receiving power, and a first terminal is provided in the main body to supply power to the electrostatic precipitating filter. The electrostatic precipitating electrostatic filter is provided with a second terminal, and when the electrostatic precipitating electrostatic filter is inserted into the main body, the second terminal is connected to the first terminal so that the electrostatic precipitating electrostatic filter can receive power.

However, in such an air cleaner, the connection between the first terminal and the second terminal is made inside the main body, which cannot be confirmed by the user. There is a problem that power may not be supplied.

The present invention is to solve such a problem, an object of the present invention is to provide a stable air connection between the first terminal provided in the electrostatic precipitating electrostatic filter is installed on the main body and the first terminal provided in the main body To provide a purifier.
