Description

[Detailed description of the invention] This invention is used to assemble an ionizer that is installed between the dust-containing air intake and the dust collection part in an air purifier and plays the role of ionizing the dust in the intake air. The present invention relates to a discharge electrode.

The ionizer has a structure in which ground electrodes and discharge electrodes are fixed to a frame in alternating rows, and a high voltage is applied to the discharge electrodes to generate corona discharge between them and the ground electrodes.

Conventionally, the discharge electrode used to assemble this ionizer is a long and thin piece of metal, with an appropriate number of thorn-like protrusions attached to one side of the metal plate at appropriate intervals. Therefore, it was necessary to create a structure on the side of the metal plate to attach the thorn-like protrusion parts, and to attach the thorn-like protrusion parts to each structure, which increased the manufacturing process of the discharge electrode. The disadvantage was that it was troublesome and the production cost of the ionizer was relatively high.

Also, Utility Model Publication No. 48-964, Japanese Patent Application Publication No. 59-
In the discharge electrode described in Publication No. 102459, each thorn-like protrusion is cut directly from the surface of a metal plate, so there is uncut portion of the metal plate between the parallel thorn-like protrusions. It is not possible to insert a ground electrode between the rows of barbed protrusions. Therefore, there is a drawback that it is not possible to accurately support each discharge electrode at the center position of each ground electrode to improve discharge efficiency.

The present invention aims to provide a discharge electrode for an ionizer of an air cleaner that can eliminate the above-mentioned conventional drawbacks.

An embodiment of the present invention will be described below based on the drawings. 1 is a single metal plate, 2 is a plurality of cut and raised plates,
These are cut and raised so as to stand up in parallel from the metal plate 1 at a constant interval and at intervals such that the ground electrode plate is inserted within these intervals. Reference numeral 3 denotes thorn-like protrusions, which are integrally provided in an appropriate number on the side of each cut-and-raised plate 2 at appropriate intervals.

In the discharge electrode constructed as described above, by simply fixing the metal plate 1 to a frame, a plurality of discharge electrodes are installed in parallel at regular intervals at a time. The ionizer is assembled by installing a ground electrode between each discharge electrode. In that case, use a ground electrode made by cutting and raising the ground electrode plates so that they are spaced a certain distance apart and located at the center of the gap between the discharge electrodes, and then stack the two metal plates on top of each other and attach the frame to the frame. By simply fixing the ionizer in a state where the plurality of discharge electrodes and the plurality of grounding electrodes are arranged in an alternating manner, the assembly of the ionizer can be made more efficient.

Since the present invention is constructed as described above, discharge electrodes having the number and dimensions necessary for assembling ionizers in air purifiers of various sizes can be cut out from a single metal plate by press working. Therefore, it is easy to manufacture the discharge electrode, and when assembling the ionizer, there is no need to handle the discharge electrodes one by one, which simplifies the ionizer assembly process and reduces the production cost of the ionizer. Furthermore, since each discharge electrode can be accurately supported at the center position of the interval between each ground electrode, the discharge efficiency is increased, which has advantages such as being useful for increasing the dust collection efficiency of the air cleaner.
