The supplied air is generated into a plurality of dispersed bubbles through the plurality of bubble generating holes 5 formed in the nozzle cover 3 of the bubble supply nozzle after passing through the connecting pipe 25. The bubbles thus generated pass through the lower space of the pulsator 19 connected to the rotary shaft 21 and are supplied to the laundry being washed in the washing tank 15.

The nozzle body (1) and the nozzle cover (3) constituting the bubble supply nozzle has conventionally used a method of bonding to each other by ultrasonic fusion. However, the ultrasonic fusion method has a problem that the noise is so severe that the operator must wear earplugs during the operation. In addition, the fusion of the nozzle body and the cover was incorrectly separated frequently, there was a problem that the noise is poor and the effect of generating air bubbles thereby.

As shown in FIGS. 2 and 3, the bubble supply nozzle has a circular compressed air inlet (7), which is a passage of compressed air flowing from the air pump, and has screw fixing members (9) formed on both sides thereof. It consists of the inclined nozzle cover 3 in which the nozzle main body 1 and the many bubble generation hole 5 were formed. In particular, the nozzle body 1 and the nozzle cover 3 is coupled to the ultrasonic fusion method with reference to FIG. 3, which shows a cut line A-A 'of the bubble supply nozzle.

In addition, referring to FIG. 4, the method of fixing the bubble supply nozzle is fixed to the rib 29 formed at the bottom bottom of the washing machine reservoir 17 using the fixing screw 27 and the bottom of the reservoir 17. A certain distance away from the. That is, as shown, a pair of ribs 29 to match the screw fixing member (9) of the bubble supply nozzle correspondingly and used a method of fixing using a fixing screw (27).

In addition, a filter is inserted into the bubble supply nozzle to prevent the movement of dust, clothing debris, etc., as necessary.

However, in the conventional bubble supply nozzle, the ultrasonic fusion unit combining the bubble supply nozzle and the nozzle cover is frequently separated as described above, resulting in noise failure of the washing machine, and air bubbles are not formed. In addition, there was a problem that causes noise due to noise generated so that the operator must use an earplug when ultrasonic welding.

[Purpose of designation]

The object of the present invention is to provide a bubble supply nozzle with a simple structure and easy installation.

Another object of the present invention is to provide a bubble supply nozzle having a structure that can be produced without using an ultrasonic welding process that causes pollution.

Still another object of the present invention is to provide a bubble supply nozzle which can improve productivity by saving time used for installation of the bubble supply nozzle.

Summary of the proposal

Bubble supply nozzle of the present invention for this purpose, by removing the lower surface of the bubble supply nozzle, and forming a protruding surface on the bottom bottom of the reservoir to correspond to the removed lower surface, the bubble supply nozzle is coupled to the projecting surface When it is configured to form a space that can move the air therein, and also characterized in that the nozzle body and the nozzle cover formed with a bubble generating hole on the surface is formed in one piece.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

[Explanation of specific example of design]

Bubble supply nozzle according to the present invention is a bubble supply nozzle consisting of a nozzle body and a nozzle cover manufactured by the conventional ultrasonic welding, the lower surface is composed of a single part of the space, the protruding surface is formed on the lower bottom surface of the reservoir When it is combined with the nozzle of the present invention is to block the space is a bubble supply nozzle configured to move the air passing through the connecting pipe.

The form of the bubble supply nozzle according to the present invention is composed of a nozzle body 31 in which a bubble generating hole 33 is formed, as shown in FIG. In particular, unlike the conventional ultrasonic welding, the nozzle cover in which the bubble generating hole 33 is formed in the nozzle body 31 is integrated.

Referring to FIG. 6, which is a cross-sectional view taken along the line A-A 'of FIG. 5, the bubble supply nozzle of the present invention has a curved compressed air inlet 39 and a screw fixing which have essentially the same function as the conventional one. The member 35 is formed. The compressed air inlet 39 is coupled to the connecting pipe 25. However, it can be seen that the lower surface is removed from the portion adjacent to the compressed air inlet 39 to the bottom of the plurality of bubble generating holes 33 and is left as a space. In addition, the nozzle body 31 according to the present invention is integrated, including the bubble generating hole (33).

Bubble supply nozzle 31 of the present invention having a structure as described above is coupled to the protruding bottom surface 37 formed in the bottom of the reservoir (17). Referring to FIG. 7, a screw fixing groove having a position corresponding to the screw fixing member 37 is formed on the protruding bottom surface 37 and is coupled by a fixing screw. The fixing screw is essentially the same as the conventional one. In addition, the guide 41 is formed inside the screw fixing groove to facilitate coupling with the nozzle body 31.

The guide 41 prevents the movement of the nozzle body 31 and prevents bubbles from leaking through the left and right gaps of the bottom surface.
