That is, a coin is put into the coin box 112 or a card is put into a card reader 114 to make a payment.

When the payment of the charge is completed through the charge processing device 110, the commercial drum washing machine 200 is driven by a customer, and the commercial drum washing machine 200 is operated by operating the control panel 222. ) Is driven.

On the other hand, the washing method of a commercial drum washing machine according to the present invention, as shown in Figure 18, first, the commercial drum washing machine 200, washing time, rinsing time, water level, When the water supply time is set, and the appropriate fee is paid accordingly, the washing stroke, the rinsing stroke, and the dehydrating stroke are performed according to the set conditions to clean the washings.

Specifically, the washing process of the commercial drum washing machine 200 is a washing stroke (Wash) to remove the contamination of the washing while the drum 208 is rotated at a low speed after the detergent and water is supplied to the tub 206, tub ( After the clean water is re-supplied to the 206, the drum 208 is rotated at a low speed, and the rinsing strokes (Rinse1, Rinse2, and Rinse3) and the drum 208 at high speed to rinse the washing water in the washing stroke are performed. It is rotated and consists of a dehydration stroke (Spin) for centrifugal dehydration of the rinsed water in the rinse stroke (Rinse1, Rinse2, Rinse3).

In the washing stroke (Wash), water and detergent are supplied to the tub 206 by the water supply device 230 and the detergent supply mechanism 250, and when the water is supplied to the tub 206 up to the set level, the drum 208 is rotated at a low speed by the motor 212 to wash the washings introduced into the drum 208 (see St1 and St2).

That is, the water is supplied to the inside of the tub 206 by the water supply device 230 so as to be contained in the tub 206 up to the set water level, the detergent introduced into the detergent supply mechanism 250 is the water supply device 230 After mixing with the water supplied by the) is supplied to the inside of the tub 206 with the water.

When the drum 208 is rotated during the set washing time to complete the washing of the washing material, the driving of the drum 208 is stopped, and the water used for washing in the tub 206 is externally discharged by the drainage device 240. Is drained to (see St3).

In addition, in the rinsing cycles (Rinse1, Rinse2, Rinse3), the drum 208 is rotated at high speed to centrifugally dewater water and detergent from the washings washed in the washing stroke (see St4).

Typically, the dehydration is divided into the liver deboning and the main shell depending on the rotational speed and the driving method of the drum 208, the liver dehydration is the drum (LP) capable of centrifugal dehydration of the cleaning material while the motor 212 is repeatedly on / off 208 is rotated, and the main shell causes the motor 212 to constantly rotate the drum 208 at a higher ALPM than the gantal.

Dehydration performed in the rinse strokes (Rinse1, Rinse2, Rinse3) is to perform only dehydration.

When the dehydration of the cleaning material is completed, clean water is supplied to the water supply time set in the tub 206 and at the same time the drum 208 is rotated at a low speed by the motor 212 to the inside of the drum 208. The injected cleaning water is rinsed (see St5).

Thus, since the commercial drum washing machine 200 proceeds at the same time as the water supply and rotation of the drum 208 during the rinsing, the rinsing time is compared with the case where the water supply of the water and the rotation of the drum 208 are performed separately. It is greatly shortened.

When the drum 208 is rotated for a set rinsing time and the rinsing of the washing water is completed, driving of the drum 208 is stopped, and water used for rinsing in the tub 206 is externally discharged by the drainage device 240. Is drained to (see St6).

The rinsing stroke (Rinse1, Rinse2, Rinse3) as described above is repeatedly carried out up to a set number of times so that the contaminants, detergent components and bubbles contained in the cleaning material can be completely removed, the rinsing stroke (Rinse1, Rinse2, The number of repetitions of Rinse3) is generally performed three times, but the number of times of setting may be increased or decreased depending on the rinsing conditions of the cleaning material.

In addition, in the dehydration stroke (Spin), the drum 208 is rotated at high speed so that water is completely centrifugally dewatered from the rinsing water rinsed in the rinse stroke (Rinse1, Rinse2, Rinse3), and the drainage device 240 Dehydrated water is drained to the outside (see St13 and St14).

In the spin-drying operation (Spin), the cleaning material is firstly deintercalated, and then second separation is performed to remove most of the water contained in the cleaning product.

As such, when the dewatering and draining of the washing water is completed, the commercial drum washing machine 200 is stopped.

In particular, the rinsing stroke will be described in more detail with reference to FIG. 19.

First, when the rinsing stroke (Rinse1) is carried out after the washing stroke (Wash) is completed, the drum 208 is rotated by the motor 212, water, detergent, foam, etc. contained in the washing water during the washing stroke Is deprived (see St20).

As described above, the water, detergent, foam, etc. separated from the washing water are discharged to the outside of the commercial drum washing machine 200 by the drainage device 240.

Then, the water used for rinsing the cleansing water by the water supply device 230 is supplied to the inside of the tub 206, and the water supply by the water supply device 230 is compared with the first set time. It is determined whether the drum 208 is driven. (See St21 and St22.)

That is, when the first set time is greater than the water supply time, only water is supplied to the tub 206 by the water supply device 230, but when the water supply time is greater than or equal to the first set time, the water supply device 230 is provided. The tub 206 is supplied with water, and the drum 208 is rotated at a low speed by the motor 212 to rinse the washing water.

The first set time is a time at which water is supplied by the water supply device 230 to a minimum rinsing level of the tub 206 in which the rinsing performance of the cleaning product is secured by the rotation of the drum 208.

Accordingly, after the first set time, the tub 206 is rotated while the drum 208 is rotated to rinse the laundry, and the drum 208 may be used to improve the rinsing performance of the cleaning product. The direction of rotation is reversed by 212).

On the other hand, it is determined whether the water supply device 230 is sealed by comparing the time when the water supply is performed by the water supply device 230 and the second set time (see St24).

That is, when the second set time is greater than the water supply time, the water supply is supplied to the tub 206 by the water supply device 230 and the drum 208 is rotated at a low speed by the motor 212. If the water supply time is greater than or equal to the second set time, the water supply device 230 is sealed to stop the water supply and the drum 208 is rotated at a low speed by the motor 212 (see St25).

Since the second set time is a time at which water is supplied by the water supply device 230 to an optimal rinsing water level set according to the quantity and type of the washing water, the rinsing performance of the washing water is maximized after the second setting time. .

When the drum 208 is rotated in the state where water supply is completed as described above and the rinsing of the washing water is performed until the third set time, the rotation of the drum 208 is stopped to rinse the washing water, and the drainage device ( 240 is activated to drain the water used to rinse the cleaning product (see St26, St27 and St28).

The third set time is an optimal rinsing time set in advance according to the amount and type of the cleaning material.

On the other hand, when the water contained in the tub 206 is completely drained by the drainage device 240, it is determined whether to re-run the hangup administration by comparing the number of times the drainage performed by the drainage device 240 with the set number of times. Done.

That is, when the number of times drained by the drainage device 240 is smaller than the set number of times, the rinsing stroke is repeatedly performed. When the number of times drained by the drainage device 240 is more than the set number of times, the rinsing stroke is performed. After (Rinse1, Rinse2, Rinse3) is finished, it enters spin dehydration (Spin).

Therefore, the row rinsing stroke is repeatedly executed up to the set number of times.

10 is an exploded perspective view illustrating a detergent supply mechanism of a commercial drum washing machine according to the present invention, and FIGS. 11 and 12 are cross-sectional views taken along line AA and BB of FIG. 10, and FIG. 13 according to the present invention. 14 is a plan view showing a detergent box body and a detergent box cap of the detergent supply mechanism, and FIGS. 14 and 15 are cross-sectional views taken along line CC and DD of FIG. 13, and FIG. 16 is a view of the detergent supply mechanism according to the present invention. Detergent box body and detergent box cap is an exploded view, Figure 17 is a perspective view of the lower portion of the detergent box body of the detergent supply mechanism according to the present invention.

For reference, the same reference numerals are given to the same or similar components, and detailed description thereof will be omitted.

The detergent supply mechanism of the commercial drum washing machine according to the present invention is connected to the water supply bellows 236 of the water supply device 230, as shown in Figures 8 to 17, the detergent box housing (opening the front and top) 252, a detergent box 254 detachably installed in the detergent box housing 252 in a front-rear direction, and having a detergent contained therein, and mounted on an opened upper surface of the detergent box housing 252. It is connected to the water supply hose 232 of the water supply device 230 is configured to include a dispenser cover (256) for discharging the water inside the detergent box (254).

The detergent box housing 252 is mounted on the rear surface of the control panel 222 so that the front surface communicates with the opening hole 222A formed in the control panel 222.

The drain box 253 to which the water supply bellows 236 is connected may protrude from a lower portion of the detergent box housing 252 so that detergent or water falling from the detergent box 254 may be supplied into the tub 206. Is formed.

The detergent box 254 is inserted into the opening hole 222A of the control panel 222 so that the detergent box body 260 is provided with a detergent accommodating part 262 for receiving powder detergent, softener and bleach; A front panel 270 mounted on the front surface of the detergent box body 260 and disposed in front of the opening hole 222A of the control panel 222 and having a handle 272 formed at one side thereof; It comprises a detergent box cap 280 mounted on the upper surface of the) and the removal prevention means 320 formed on the lower portion of the detergent box body 260 so as not to be removed at random when the detergent box 254 is withdrawn.

The detergent box body 260 is formed in a box shape having an upper surface and a rear surface, and a front portion 264 on which the front panel 270 is mounted is formed on the front surface, and both sides of the detergent box body 260. The partition side wall portion 268 is formed long in the front-rear direction between the wall portions 265 and 266.

The detergent accommodating part 262 is formed between the compartment side wall part 268 and the right wall part 265 in a longitudinal direction to accommodate the first detergent accommodating part 300 and the compartment side wall part 268. And a second detergent accommodating part 310 formed between the left wall part 265 in the front and rear direction to accommodate the softening agent and the bleaching agent.

Here, the first detergent receiver 300 has a blocking wall 302 formed on the rear surface of the first detergent receiver 300 so that the powder detergent does not fall into the detergent box housing 252 in a lump state by water sprayed from the dispenser cover 256. The detergent amount setting wall 304 is formed at a position spaced apart from the front panel 270 by a predetermined distance so that the detergent capacity acceptable to the first detergent accommodating part 300 is set.

The barrier wall 302 and the detergent amount setting wall 304 are plate members formed horizontally in the horizontal direction, and both ends of the barrier wall 302 and the right wall portion 265 are connected to the partition side wall portion 268 and the first wall portion 265, respectively. The powder detergent contained in the detergent accommodating part 300 is formed to be spaced apart from the bottom surface 301 of the first detergent accommodating part 300 to be discharged to the detergent box housing 252.

The lower bottom surface 301 of the blocking wall 302 has a semi-circular discharge hole 306 is formed to facilitate the discharge of water or detergent from the first detergent receiving portion 300.

The detergent amount setting wall 304 is formed at a position corresponding to the opening hole 222A when the detergent box 254 is maximally drawn out of the opening hole 222A of the control panel 222 to accommodate the first detergent. It is to set the space in which the powder detergent is injected into the unit 300.

That is, as the detergent box 254 is pulled forward, the front part of the first and second detergent receivers 300 and 310 is opened to form an input space S into which a powder detergent, a softener, a bleach, or the like is introduced. do. At this time, the input space (S) is formed to the maximum size at the time when the detergent box 254 is drawn out to the maximum, the detergent amount setting wall 304 is the opening hole (d) when the maximum withdrawal of the detergent box (254) It is formed perpendicular to the position corresponding to 222A to limit the volume of the detergent can be accommodated in the first detergent receiving portion 262.

Thus, the detergent amount setting wall 304 is inclined in the vertical direction so that the upper end is disposed behind the opening hole 222A and the lower end is disposed in front of the opening hole 222A.

Therefore, since the detergent amount setting wall 304 is formed to be inclined, an injection mold is easily taken out during the injection molding of the detergent box body 260, and an upper end of the detergent amount setting wall 304 is formed in the opening hole 222A. Since it is located inside, the phenomenon that the powder detergent is introduced into the space behind the detergent amount setting wall 304 is prevented.

Of course, it is true that the commercial washing machine 200 changes the amount of detergent injected into the detergent box 254 according to the washing capacity, but recently, since the washing performance of the powder detergent is very excellent, the amount of detergent actually required for washing is greatly reduced. Since there is a tendency to increase, it is not necessary to move the position where the detergent amount setting wall 304 is formed rearward for the purpose of increasing the accommodation space of the powder detergent.

In addition, a softener accommodating part 312 having a softener on the left side and a right side thereof and a bleach accommodating part 311 accommodating a bleach are formed in the second detergent accommodating part 310.

The bleach receiving portion 311 and the softening agent receiving portion 312 as described above are formed in a box-type structure in which the upper surface is opened at a position spaced apart from the bottom surface 311 of the second detergent receiving portion 310 by a predetermined height. .

The bleach receiving portion 311 is formed long in the front and rear direction along the partition side wall portion 268, the bleach input portion (S1) is formed in a predetermined width in the front portion, the bleaching agent receiving portion (311) at a predetermined height on the bottom surface of the rear portion The phone tube 313 is formed to protrude.

The softener accommodating part 312 is elongated in the front-rear direction along the left wall part 266, and the softener injecting part S2 is formed at a predetermined width in the front part so as to be located behind the bleach input part S1. The siphon tube 314 is protruded to a predetermined height on the bottom of the rear portion.

On the other hand, the second detergent receiving portion 310 is partitioned from the bottom of the bleach receiving portion 311 and the softening agent receiving portion 312 so as to partition the inside into the bleach receiving portion 311 and the softening agent receiving portion 312. The rib 316 protrudes upward to a predetermined height.

The lower compartment rib 316 is formed in the detergent input space (S) of the second detergent receiving portion 310 which is opened at the time of maximum withdrawal of the detergent box 254 in the left and right direction and the bleach receiving portion 311 and The first lower compartment rib 316A which defines a space into which the detergent of the softening agent accommodating part 312 is injected, and the side surface of the second detergent receiver 310 among both ends of the first lower compartment rib 316A. A second lower compartment rib 316B formed rearward from the right end spaced apart from the right end to form a flow passage 315 between the compartment side wall portion 268 and a rear end of the second lower compartment rib 316B; And a third lower partition rib 316C formed rearwardly at a middle point between the partition side wall portion 268 and the left wall portion 266 after being formed to the left in parallel with the first lower partition rib 316A. .

Here, the first lower compartment rib 316A is formed long in the left and right directions in the open input space S of the second detergent receiving part 310 at the time of maximum withdrawal of the detergent box 254, so that the bleach input hole ( S1) and the softener inlet S2 are formed. The bleach input unit S1 as described above is formed at the front of the first lower compartment rib 316A, and the softener input unit S2 is formed at the rear of the first lower compartment rib 316A.

The left end of the first lower compartment rib 316A is connected to the left wall portion 266 of the second detergent receiver 310, and the right end thereof is a partition side wall part 268 of the second detergent receiver 310. ) Is spaced at a predetermined interval. The right end of the first lower compartment rib 316A is spaced apart from the compartment side wall portion 268 at an interval smaller than the width half length of the second detergent receiver 310.

In addition, the second lower compartment rib 316B is formed to extend rearward from the right end of the first lower compartment rib 316A, so that the bleaching agent is injected between the softener input part S2 and the partition side wall part 268. A flow passage 315 for flowing the bleach injected into the portion S1 to the rear portion is formed.

The flow passage 315 acts as a structural bottleneck, since the water mixed with the softener is more viscous than the water mixed with the bleach, so that the water mixed with the bleach flows into the flow passage 315. Preferably, the bleach input unit S1 is formed in front of the first lower compartment rib 316A.

Therefore, as described above, the softener receiving part 312 and the bleach receiving part 311 are formed in the front and rear directions on the inner left and the right side of the second detergent receiving part 310 and the second detergent receiving part 310. Since the bleach input unit S1 and the softener input unit S2 are disposed in front and rear in the detergent input space S, the softener receiving unit 312 and the bleach receiving unit ( The maximum withdrawal distance of the detergent box 254 is minimized than the structure in which 311 is disposed before and after, and the bleach input unit S1 is disposed more than the structure in which the bleach input unit S1 and the softener input unit S2 are disposed left and right. And the size of the softener inlet (S2) is increased.

The rear wall portion 317 is formed on the rear surface of the second detergent receiver 310 at a height higher than that of the siphon tubes 313 and 314.

The rear wall portion 317 is formed with an overflow portion 317B at the upper middle portion so that the bleach and the softener or the water may overflow into the detergent box housing 252 when the bleach and the softener are over-injected or supercharged with water. .

The overflow portion 317B is formed at a relatively low height than both end portions of the rear wall portion 317.

In particular, the bleach receiving portion 311 and the softening agent receiving portion 312 is formed in a structure in which a portion of the siphon tube 313, 314 is formed to a predetermined depth raised downward, the second detergent receiving portion 310 Shield wall 318 is formed vertically on the bottom surface 311 of the () so that the lower front of the siphon tube (313, 314) can be shielded.

The shielding wall 318 is the siphon pipe 313 (so that the air pressure can be applied to the lower end of the siphon pipe 313, 314 when the detergent box 254 is inserted into the opening hole 222A) ( At 314, it is formed at a position spaced forward.

Therefore, since a predetermined air pressure is applied to the lower part of the siphon pipes 313 and 314 when the detergent box 254 is closed, the bleach and the softener stored in the bleach receiving part 311 and the softening agent receiving part 312. Is prevented from being discharged to the bottom surface 311 of the second detergent receiver 310 through the siphon pipes 313 and 314 and the siphon caps 285 and 286 which will be described later. do.

The front panel 270 is hooked to the front portion 264 of the detergent box body 260 and is fastened and fixed by the fastening bolt 274.

That is, the front portion 264 and the front panel 270 is formed so that the hook hole and the hook is opposed to each other so that the front panel 270 is mounted on the front portion 264, so that the fastening holes or fastening bosses face each other. Is formed and fastened by the fastening bolt 274 is fixed. Therefore, since the front panel 270 is firmly mounted and fixed to the front part 264 of the detergent box body 260, any detachment of the front panel 270 is prevented.

The detergent box cap 280 is a plate-shaped member mounted on the upper surface of the second detergent accommodating part 310. The front part includes a seating part 319 formed at the front part of the second detergent accommodating part 310. ) Is fixed to the top, and the rear portion is fixed to the top of the rear wall portion 317 formed on the rear surface of the second detergent receiving portion (310).

The first fitting hole 319A is formed through the seating portion 319 in the vertical direction, and the first fitting protrusion is inserted into the first fitting hole 319A on the lower surface of the front of the detergent box cap 280. 281 protrudes downward.

The second fitting protrusion 317A protrudes rearward from the upper rear surface of the rear wall part 317, and the second fitting protrusion 317A is fitted into the rear surface of the lower surface of the detergent box cap 280 so as to be engaged. The close contact portion 282 on which the holes 282A are formed protrudes downward.

The close contact portion 282 is formed to be in close contact with the upper rear surface of the rear wall portion 317.

Thus, the detergent box cap 280 is firmly mounted to the detergent box body 262 by the first and second fitting holes 319A and 282A and the first and second fitting protrusions 281 and 317A. In addition, the first and second fitting protrusions 281 and 317A are not exposed to the outside when the detergent box 254 is pulled out, thereby preventing the phenomenon of being arbitrarily removed by the customer.

On the other hand, the detergent box cap 280 has a bleach inlet (283) is formed in a portion corresponding to the bleach input unit (S1) and water is added, a softener in a portion corresponding to the softener input unit (S2) And a softener inlet 284 into which water is introduced, and the siphon tube 313 is formed at a portion corresponding to the siphon tubes 313 and 314 of the bleach receiving unit 311 and the softener receiving unit 312. Siphon caps 285 and 286 are respectively formed to cover 314.
