As a preferred embodiment of the present invention, a device for controlling a collaborative robot includes a collision detection unit configured to sense a collision of the collaborative robot; a control unit configured to control an operation mode of the collaborative robot when the collision detection unit senses the collision; and a collision countermeasure unit configured to apply, when the collision detection unit senses the collision, a collision compensation value to each of a plurality of joints in the collaborative robot so as to change a proceeding direction of a force applied to the each of the plurality of joints.

Device and method for controlling cooperative robot

A novel washing method of a washing machine that is capable of performing a washing operation of laundry with reduced washing water consumption and low power consumption and, in addition, sterilizing the laundry is disclosed. The washing method includes supplying washing water containing detergent into a tub to perform a high-concentration washing process, and, before or after the high-concentration washing process, supplying steam into a drum.

Method for washing of washer

A method of operating a washing machine, by which a steam generator is disclosed, laundry and the washing machine itself can be safely protected in a manner that an error occurrence of the washing machine is accurately detected and by which a following cycle such as a washing cycle, a drying cycle and the like can be effectively performed despite the failure of the washing machine. The present invention includes a step (a) of supplying water to a steam generator, a step (b) of supplying steam into a drum by generating heat from a heater of the steam generator, and a step (c) of detecting abnormality of the washing machine while the step (a) or (b) is carried out.

Operating method of the laundry machine

A washing machine that performs a washing operation using eat high-temperature steam and a washing method of the same are disclosed. The washing method includes (a) driving a washing heater () mounted in a tub () to increase the interior temperature of the tub (), and (b) driving a steam heater () mounted in a steam generation unit (), such that high-temperature steam is generated and the high-temperature steam is supplied into the tub (), to increase the interior temperature of the tub (). A washing operation including the (a) step and the (b) step, which are combined either in the order of the (a) step-&#x3e;the (b) step-&#x3e;the (a) step or in the order of the (b) step-&#x3e;the (a) step-&#x3e;the (b) step, is carried out such that the interior temperature of the tub () is increased to a target temperature level. Consequently, the present invention has the effect of increasing the decomposition of detergent or contaminants by the provision of a washing algorithm, in which a washing water heating operation and a high-temperature steam injecting operation are combined, efficiently removing contaminants that are not removed only by heating the washing water, and, furthermore, increasing the sterilization efficiency.

Spray steam in drum type washer and control method

A controlling method of a laundry machine is disclosed. The controlling method includes supplying wash water into a tub up to a predetermined water level, and controlling On/Off of a steam heater and a tub heater until a temperature inside the tub or a drum reaches a predetermined temperature at the predetermined water level. By using both the tub heater and steam heater in conjunction with a controlling of a water supply valve in order to acquire the predetermined water level and predetermined tub temperature, the controlling method is advantageous to improve energy efficiency of the laundry machine.

Controlling method of a laundry machine

A method for controlling a washing machine is disclosed. The method for controlling a washing machine having a steam generator includes a step of automatically discharging water of the steam generator outside of the steam generator during the operation of the washing machine. Therefore, according to the present invention, foreign substances may be efficiently prevented from precipitating in the steam generator.
