Description

Spacer Nozzle Spacer (SPACER FOR NOZZLE)

The present invention relates to a spacer for an annular nozzle, and more particularly, to a spacer for an annular nozzle which is detachably mountable to a discharge port of an annular nozzle of an electric fan, so that even if foreign substances such as dust are caught in the spacer, So as to be able to cleanly remove a foreign matter adhering to the spacer.

Generally, the fan features a structure that blows the wind forward by rotating the wing through the driving force of the motor. This wing-type rotary fan is composed of a lower body placed on the floor and having a column at its center, a motor horizontally provided on the upper portion of the lower body and having a rotary shaft projected forward, wing mounted on the rotary shaft for generating wind, And a cover net covering the periphery of the wing.

However, the wing-rotary type fan having the above-described configuration has a problem that safety hazards are caused by children frequently putting fingers or chopsticks into the cover net.

In order to solve the above problems, there has been known a fan without a wing. An example of such a fan is a fan of Korean Patent No. 1113034 (hereinafter referred to as a "conventional fan").

A conventional fan is a bladeless fan assembly for generating airflow, comprising: a nozzle mounted on a base portion; a means for generating an air flow through the nozzle, the means being located in the base portion; A mouth (mouth) formed by a first opposing face and a second opposing face for releasing the air flow, and spacer means for spacing the first opposing face and the second opposing face of the nozzle Wherein the nozzle includes an inner passage for receiving the air flow from the base portion, the nozzle being configured to extend around the opening, wherein the air flow from the mouth portion causes the non- Air is introduced into the opening from the outside of the fan assembly, the spacer means is integrated with the first opposing face, Wherein one of the opposing surfaces of the nozzle is biased toward the other opposing surface so that the spacer means abuts the second opposing surface and separates the first opposing surface from the second opposing surface, .

However, since the nozzles constituting the conventional fan are provided integrally with the first opposing face, there is a problem in that even if foreign matter such as dust remains in the periphery of the spacer, it is impossible to clean the foreign object completely .

"Fan assembly" of Korean Patent Registration No. 1331488 (Nov. 13, 2013)

Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art,

It is an object of the present invention to provide an air conditioner in which a spacer is detachably inserted into an air outlet of an annular nozzle of an electric fan so that even if foreign substances such as dust are caught in the spacer, the spacer is occasionally separated, And a spacer for an annular nozzle.

Another object of the present invention is to provide a spacer for an annular nozzle which can improve durability by constituting the spacer with an inner and outer plate member and a plurality of spacer plates.

It is a further object of the present invention to provide an annular nozzle spacer which can more smoothly discharge wind by further forming an inclined surface or an inclined curved surface for guiding the wind radiated to the inner side surface of the discharge orifice hole to the surface of the coiled- .

Another object of the present invention is to provide a spacer for an annular nozzle which makes it possible to more firmly fix the spacer to the discharge port of the annular nozzle through the formed locking jaws of the inner and outer plate members.

In order to achieve the above object, a "spacer for an annular nozzle" according to the present invention is a spacer inserted into a discharge port formed in an annular nozzle of a fan without a wing, and the annular nozzle forms a central opening communicating in the fore- Wherein the outlet is formed to be spaced apart from the outer surface of the inner circumferential plate of the annular nozzle and the inner surface of the inner plate of the mouth portion, Is formed in the shape of a ring, is detachably inserted into the discharge port, and has a discharge orifice hole around which air is blown at regular intervals.

The spacer of the "annular nozzle spacer" according to the present invention includes: an outer plate-shaped member formed on an outer periphery of the outer plate-shaped member so as to be closely contacted with an outer surface of an inner periphery plate constituting the discharge port; An inner plate member inserted into the inner plate of the mouth part constituting the outlet in such a manner as to closely contact with the inner surface of the inner plate and a plurality of space holding plates formed at radially equidistant intervals between the inner and outer plate members, .

Further, at the rear of the outer plate member of the "annular nozzle spacer" according to the present invention, at least one outer locking jaw which is hooked to the rear end of the inner circumferential plate is further formed, And at least one inner locking jaw which is hooked in front of the plate is further formed.

Further, on the inner surface of the discharge hole of the "spacer for annular nozzle according to the present invention ", there is further formed an inclined surface facing outward from the rear side or a curved inclined surface curved inwardly so that the discharge passage narrows from the rear to the front .

As described above, according to the present invention, since the spacer is detachably inserted into the discharge port of the annular nozzle of the electric fan, the spacer can be removed at any time to cleanly remove foreign matters remaining in the spacer, It is possible to eliminate the damage caused by the health of the user.

In addition, the present invention can improve the durability of the spacers by configuring the spacers with the inner and outer plate members and a plurality of spacing plates so that the spacers are inserted and fixed in the discharge ports of the horizontal nozzles, It is possible to prevent narrowing of the interval.

In addition, the present invention further provides an inclined surface or an inclined curved surface for guiding the wind radiated to the inner side surface of the discharge orifice hole to the surface of the nose, thereby allowing the wind to be released more smoothly.

The present invention also has the effect of more firmly fixing the spacer to the discharge port through the locking jaw formed of the inner and outer plate members.
