And a bleach feed water passage 182 is formed so that cold water flows from the third hose connection portion 186C to the portion opposite to the bleach receiving portion 172, and accommodates the softener in the fourth hose connection portion 186D. The softener feed passage 184 is formed such that cold water flows to the unit 174.

In addition, the water supply hole 190 may include a plurality of detergent water supply holes formed at an upper side of the first detergent accommodating part 160 such that water in the detergent water supply passage 180 is supplied to the first detergent accommodating part 160. 192, a single number of bleach water supply holes 194 formed above the bleach receiving part 172 so that the water in the bleach supply water passage 182 is supplied to the bleach receiving part 172, and the softener water supply passage 194. It consists of a plurality of softener water supply holes 196 formed on the upper side of the softener receiving portion 174 so that water in the 184 is supplied to the softener receiving portion 174.

The detergent water supply hole 192 is formed in a plurality of portions facing the inner surface of the first detergent receiving portion 160, the bleach water supply hole 194 is a portion facing the upper surface of the bleach receiving portion 172 Is formed in, the softener water supply hole 196 is formed in a portion facing the softener receiving portion (174).

The detergent water supply hole 192 is formed such that water is inclinedly sprayed to the inner side surface of the first detergent receiver 160 so that the powder detergent contained in the first detergent receiver 160 may be smoothly washed down.

That is, since the powder detergent is likely to remain on the inner surface of the first detergent accommodating part 160 without being completely washed off, the detergent water supply hole 192 is the inner surface of the first detergent accommodating part 160. To spray water.

The bleach water supply hole 194 and the softener water supply hole 196 are the bleach receiving part 172 and the softener so that the bleach and the softener contained in the bleach receiving part 172 and the softening agent receiving part 174 can be released well. Water is formed to be vertically sprayed into the interior of the receiving portion (174).

That is, when the bleach and the softening agent are not easily released and the viscosity is high, the siphon phenomenon of the siphon tubes 173 and 175 and the siphon caps 148 and 149 does not occur smoothly, and thus the discharge performance is lowered. Water is vertically injected into the bleach and the softener by the bleach feed hole 194 and the softener feed hole 196 to crush the bleach and the softener by hydraulic pressure.

In particular, a softener water supply passage 184 is formed at a portion of the lower panel 116A facing the softener receiving unit 174, like the detergent water supply passage 180, and a plurality of softener feed passages 184 are formed along the softener feed passage 184. A softener feed hole 196 is formed.

When water is injected into the whole of the softener container 174 by the softener water supply passage 184 and the plurality of softener water supply holes 196, the crushing performance of the softener contained in the softener container 174 is greatly improved. .

Looking at the operation and assembly process of the detergent supply mechanism of a commercial drum washing machine according to the present invention configured as described above are as follows.

First, before washing the laundry by the commercial drum washing machine 50, an appropriate amount of powder detergent, bleach and softener are added to the detergent supply mechanism 110.

That is, the detergent box 114 of the detergent supply mechanism 110 is drawn out from the opening hole 72A of the control panel 72 to the front, and the input space S of the detergent accommodating portion 122 is opened. Powder detergent, bleach, and softener are introduced into the bleach receiving unit 172 and the softening agent receiving unit 174 of the first detergent receiving unit 160 and the second detergent receiving unit 170 through the space S, respectively.

Since the detergent amount setting wall 162 is disposed below the opening hole 72A when the space S into which the powder detergent is injected is maximum, the first detergent accommodating part 160 is disposed in the detergent amount setting wall 162. Detergents are not added to the rear, which prevents waste. That is, the recent powder detergent is very excellent in cleaning performance, even if only a small amount of powder detergent in the detergent box 114, the washing performance of the laundry is sufficiently secured.

The second detergent receiving unit 170 is a detergent box cap 140 is mounted on the upper side of the wall 176, 177 opposite the bleach receiving unit 172 and the softener receiving unit 174, the detergent box cap Bleach is introduced into the bleach receiving unit 172 through a space formed in front of the 140, and a softener is introduced into the softening agent receiving unit 174 through a space formed at the rear of the detergent box cap 140.

At this time, the maximum amount of bleach introduced into the bleach receiving unit 172 is guided by the front horizontal rib 145 formed on the front part 144 of the detergent box cap 140, and the detergent box cap 140 is provided. The rear horizontal rib 147 formed at the rear portion 146 of the guided amount of the softener introduced into the softener receiving portion 174 is guided.

As described above, the front horizontal rib 145 and the rear horizontal rib 147 prevent the bleach and the softener from being excessively added.

In particular, the wall surfaces 176 and 177 are formed such that any one of the left side and the right side protrudes toward the bleach receiving portion 172, and the rear side of the protruding portion of the wall surface 177 of the softening agent receiving portion 174. The siphon tube 175 of the softener receiving portion 174 is disposed therein, and the siphon tube 173 of the bleach receiving portion 172 is located in front of the protruding portion of the wall surface 176 of the bleach receiving portion 172. ), The wall surfaces 176 and 177 are minimized compared to the structure in which the walls 176 and 177 are formed in a straight line.

Therefore, the detergent box cap 140 is reduced in length in the front-rear direction and is compactly formed, thereby expanding the space into which the softener formed between the detergent box cap 140 and the control panel 74 is added. do.

When the powder detergent, bleach, and softening agent are put into the detergent receiving unit 122 of the detergent box 114 as described above, the detergent box 114 is inserted into the opening hole 72A of the control panel 72 and the The detergent box 114 is disposed inside the detergent box housing 112.
