As shown in FIG. 2, a washing tub 100 is formed inside the dish washer main body to wash dishes, and the upper accommodating portion 110 and the lower accommodating portion 130 may be placed inside the washing tub 100. ) Is slidably installed through the guide member (not shown).

The washing water supply pipe 300 for supplying the washing water is installed in the rear of the washing tank 100, the washing water supply pipe 300 has a 'C' shape, the upper injection device 200, the central injection device 400 And connected to the lower injection device 600 is injected to the washing water supplied through the washing water supply pipe (300).

As shown in Figure 3a and 3b, the upper end of the washing water supply pipe 300 is connected to the first connecting member 210 for supplying the washing water toward the upper housing 110, the first connection member A fixing bracket 310 may be mounted to fix the connection member 210 to the upper plate of the washing tank 100.

The fixing bracket 310 is welded and fixed to the inner upper plate of the washing tank 100, both sides are bent downwardly, and the holes (not shown) are formed on both sides extending downward to form the first connection member (to be described later) 210 is fitted with the locking piece 211.

The first connection member 210 is in communication with the upper end of the washing water supply pipe 300 is coupled to one side, the lower side is formed is coupled to the rotating spraying body 230 to be described later to wash water supplied from the washing water supply pipe 300 It leads to the rotary injector (230).

The first connection member 210 is protruded from both sides so that the first connection member 210 may be mounted in holes formed at both sides of the fixing bracket 310 fixed to the inner upper plate of the washing tank 100. In response to the locking piece 211 is formed, the locking piece 211 is fitted into the hole of the fixing bracket 310 is fixed so as not to be separated.

In addition, a lower portion of the first connection member 210 is provided with a mounting portion 213 of a predetermined length having a circular cross-sectional shape so as to be inserted into and coupled to the rotary jet 230 to be described later, the mounting portion ( The central portion in which the 213 is formed is formed in communication with the rotary spraying body 230 so that the washing water supplied from the washing water supply pipe 300 flows into the inner passage of the rotary spraying body 230.

As shown in FIG. 4, the rotary jet 230 includes a flow path part 231, a wing part 233, and a connection hole 235, and is formed in a disc shape.

The rotary jet 230 has a connection hole 235 having a circular cross-sectional shape formed through a central portion thereof and is rotatably coupled to the mounting portion 213 of the first connection member 210.

The mounting portion 213 of the first connecting member 210 and the locking portion 253 of the second connecting member 250 to be described later are inserted into the connection hole 235, respectively. It is preferable that the locking portion 253 is hooked.

The flow path part 231 is formed to have different heights so as to spray the washing water guided by the connection hole 235. In addition, the wing portion 233 is formed on the upper side of the flow path portion 231, has a wing shape bent to the outside of the connection hole 235, it is formed in plurality.

5A to 5D, the flow path portions 231 of the rotary jet 230 have different heights H1, H2, H3, and H4, respectively, in order to obtain different rotational forces, Is formed with two flow path bottom, each pair of height (H1, H2, H3, H4) is formed facing each other.

That is, the flow path part 231 sequentially includes a pair of first flow path parts 231a having a height equal to H1, a pair of second flow path parts 231b having a height equal to H2, and a height of H3. It consists of a pair of 3rd flow path part 231c which has a height, and a pair of 4th flow path part 231d which is as high as H4. Therefore, the pair of flow path portions 231a to 231d having the same height are disposed on the diameter line of the rotary jet 230, respectively.

Four pairs of the first flow path part 231a to the fourth flow path part 231d are formed to face each other and have a sequential height H1, H2, H3, and H4, and the first flow path part 231a. Since the flows of the washing water according to the fourth flow path part 231d are different from each other, the flow path part 231 may send the washing water delivered by the water pressure in a different direction to the near or far while the rotary jet rotates. At this time, the rotational force is obtained by the curved shape of the wing portion 233 formed on the upper surface of the flow path portion 231.

Meanwhile, as shown in FIGS. 3A and 3B, the second connection member 250 includes a closing part 251 and a locking part 253, and the closing part 251 is the connection hole. It is formed in a circular shape having a diameter larger than 235, and serves to prevent the washing water injected from the connection hole 235 to be guided to the flow path portion 231, the center portion of the closing portion 251 to the outside Four locking parts 253 are formed to protrude and are inserted below the connection hole 235.

The locking portion 253 is spaced apart at regular intervals to fit the circumference of the connection hole 235, has a predetermined length, each end is formed in a hook shape bent outwardly the mounting portion 213 And hook. At this time, the length of the locking portion 253 is preferably extended to the end of the locking portion 253 is hooked to the mounting portion 213 inserted into the connection hole 235.

The upper rotary jetting device of the present invention having the assembly coupled to the hook as described above is easy to assemble, the tightening force is enhanced to prevent the wash water leakage, the rotation of the rotating jetting body is smoothly the advantage that the cleaning performance is improved have.

Looking at the assembly state of the upper rotary injection device according to the present invention configured as described above are as follows.

The fixing bracket 310 is welded and fixed to the inner upper plate of the washing tub 100 of the dish washing machine, and the engaging pieces 211 formed at both sides of the first connection member 210 in the holes formed at both sides of the fixing bracket 310. This fit is combined.

Then, the mounting portion 213 of the first connecting member 210, the upper end of the washing water supply pipe 300 is inserted into one side is inserted into the upper side of the connection hole 235 of the rotary jet 230, the second connection The locking part 253 of the member 250 is inserted below the connection hole 235.

In other words, the outer circumferential surface of the mounting portion 213 is inserted into the connection hole 235 of the rotary injection body 230 so as to be rotatably coupled, and in the coupled state as described above, The catching portion 253 is inserted into the lower side of the connection hole 235 and the end of the catching portion 253 is hooked to the inner circumferential surface of the mounting portion 213.

After being assembled as described above, the rotary spraying body 230 rotates as in the prior art and sprays the washing water, which is the washing water supplied to the washing water supply pipe 300 through the first connecting member 210. It is delivered to the connection hole 235 of the dead body 230 and evenly sprayed to the dirty dishes of the upper housing portion along the flow path portion 231 of the rotary spraying body 230.

Therefore, the upper injector 200 of the present invention may improve the cleaning performance by removing contaminants by spraying the washing water evenly on the contaminated tableware mounted on the upper accommodating part 110.
