The present invention discloses an isolation type tunnel washer for cleaning clothes, which comprises a closed tunnel washer box body. A partition wall is provided in the middle of the tunnel washer box body, a feeding port and a discharging port are provided at two ends of the tunnel washer box body, and the feeding port and the discharging port are respectively located at two sides of the partition wall. A water vapor separation structure is mounted between the feeding port and the partition wall, the water vapor separation structure extracts and exhausts air from the interior of the tunnel washer box body, and a first door body and a second door body which can be opened and closed are respectively mounted at the feeding port and the discharging port.

A laundry machine includes first and second washing units including first and second tubs, respectively. First and second drums are mounted inside the first and second tubs, and first and second drive units drive rotations of the first and second drums around first and second rotational shafts, respectively. The second washing unit is arranged above the first washing unit and has a smaller laundry treating capacity than the first washing unit. The first rotational shaft is not parallel to the second rotational shaft. A first recess projects downward from a rear lower surface of the second tub and is configured to heat wash water in the second tub. A metal plate member is provided on an outside lower surface of the second tub, and partially extends to the rear of the second tub to expose a bottom surface of the first recess.

Laundry treating equipment comprises a first laundry treating apparatus and a drying system. The first laundry treating apparatus includes a first laundry treating drum. The drying system includes a driving apparatus driving the first laundry treating drum to rotate, a drying component used for producing a drying airflow, and a drying airflow circulating apparatus being driven by the driving apparatus. The drying airflow circulating apparatus is used for delivering the drying airflow into the first laundry treating drum. The driving apparatus is connected to the first laundry treating drum via a clutch apparatus so as to selectively rotate with the first laundry treating drum. With the described structure provided, the laundry treating equipment allows a drying drum to rotate or be stationary via the clutch apparatus, thus facilitating the sharing of the drying system.

A water replenishment control method for a multi-drum washing machine. The washing machine comprises at least a first washing drum and a second washing drum. While the first washing drum is in a washing process, if the water level of washing water is lower than a set value, then a water replenishment process is executed, and before that, it is necessary to determine whether or not the second washing drum is executing a water replenishment process; if yes, the first washing drum pauses the water replenishment process, and the second washing drum executes precedence preferentially; if no, the first washing drum executes water replenishment process and terminates it when the water level of the washing water reaches a set water level.

A washing machine in which a first main heater is not driven while wash water stored in a first tub and wash water stored in a second tub are simultaneously heated, and a method of controlling the same. A washing machine includes: a first tub configured to store wash water; a first main heater configured to heat wash water stored in the first tub; a first sub heater configured to heat wash water stored in the first tub; a second tub configured to store wash water; and a second heater configured to heat wash water stored in the second tub, wherein a power consumption required to drive the first main heater is greater than a power consumption required to drive the first sub heater, and the first main heater is not driven while wash water stored in the first tube and wash water stored in the second tub are simultaneously heated.

A shell structure of a clothing treating device comprises a rear U-shaped plate, the rear U-shaped plate being bent at two vertical lines to form a left side wall, a right side wall and a rear side wall of a shell, with a cross section being U-shaped. The left side wall and the right side wall are respectively provided with at least one handle part, and the rear U-shaped plate is provided with an air vent communicating with an inside of the shell. As a result, the shell structure of a machine body of the clothing treating device is simplified, the strength is improved, and the assembly efficiency is improved. Also, an air duct arranged in the clothing treating device communicates with the air vent, so that the purpose of exchanging air with the outside through the air vent is realized.

A laundry processing machine according to the present invention includes a plurality of washing units that implement washing independently from each other. When the plurality of washing units implement washing simultaneously, the laundry processing machine detects the vibration amount generated and control the motor rotation speed of each washing unit to decrease the vibration generated so that damage to the laundry processing machine can be prevented.

A washing machine in which a first main heater is not driven while wash water stored in a first tub and wash water stored in a second tub are simultaneously heated, and a method of controlling the same. A washing machine includes: a first tub configured to store wash water; a first main heater configured to heat wash water stored in the first tub; a first sub heater configured to heat wash water stored in the first tub; a second tub configured to store wash water; and a second heater configured to heat wash water stored in the second tub, wherein a power consumption required to drive the first main heater is greater than a power consumption required to drive the first sub heater, and the first main heater is not driven while wash water stored in the first tube and wash water stored in the second tub are simultaneously heated.

Washed laundry that has been rinsed still contains bound acidic or basic rinsing liquid. In many cases this must be neutralized. This used to be conducted on the basis of values gained from experience, which generally resulted in only partial neutralization. Herein, sample liquid is taken continuously from the neutralization chamber (18) and, after the fine filtration of same, the pH value of the sample liquid is continuously measured by a pH value measurement device (31). In this manner a pH value control system is possible which ensures an automatic and complete neutralization of the rinse liquid still bound in the laundry after rinsing.

According to an aspect of the present disclosure, a method of treating a textile with an antimicrobial agent over a plurality of laundry cycles each including a wash cycle and a treatment cycle. The method includes (a) receiving a textile in a wash system for a first laundry cycle, (b) initiating a wash cycle comprising a detergent, (c) initiating a post-detergent treatment cycle comprising dosing the textile with a solution having a predetermined concentration of an antimicrobial agent that comprises a metallic ion, and (c) repeating steps (a)-(c) for each of a plurality of additional laundry cycles. The predetermined concentration is insufficient to achieve a predetermined antimicrobial efficacy for the textile due to the first laundry cycle alone but sufficient to achieve the predetermined antimicrobial efficacy for the textile due to a combination of the first laundry cycle and one or more of the plurality of additional laundry cycles.
