Problems solved by technology

However, if the drain water level starts to increase according to the installation conditions of household appliances (for example, the drain height), the cavitation caused by the increased water pressure of the drain pump pump body (or air gap) and the remaining water is increased. possibility of
If cavitation occurs, although the drain pump is continuously operated, the conventional home appliance cannot sufficiently drain water within a predetermined time, so that the operating time of the drain pump (ie, draining time) becomes long

Embodiment Construction

[0045] Embodiments, examples of which are illustrated in the drawings, wherein like reference numerals refer to like parts throughout, will now be described in detail. The embodiments are described below in order to explain the present invention by referring to the figures.

[0046] FIG. 3 is a block diagram illustrating a home appliance equipped with a drainage function according to an embodiment of the present invention.

[0047] Referring to FIG. 3 , a home appliance equipped with a drain function includes a controller 10 , a driver 12 , a drain pump 14 , a check valve 16 , a water level detector 18 and a display 20 .

[0048]The controller 10 is implemented with a microprocessor to control the overall operations of the home appliance equipped with the drain function. When the drainage treatment starts, the controller 10 turns on or off the drainage pump 14 according to a series of steps and minimizes cavitation so that the controller 10 can easily perform the drainage tre...

Abstract

A home appliance equipped with a drain function and a method of controlling the same are disclosed. The method of controlling a home appliance equipped with a drain apparatus includes switching ON / OFF the drain apparatus during a first time, switching on the drain apparatus during a second time after switching ON / OFF the drain apparatus, checking a variation of the water level according to a draining status, and controlling the drain apparatus based on the checked water-level variation result corresponding to the draining status.

Description

technical field [0001] The present invention relates to a household appliance having a drainage function and a method of controlling the same, and more particularly, to a household appliance having a drainage function to more efficiently perform a drainage operation and a method of controlling the same. Background technique [0002] Generally, household appliances with a drainage function can be a washing machine for washing clothes and a dishwasher for washing dishes. The washing machine includes a dehydration process after performing a washing process, or a drain process to discharge water in a tub after a rinsing process before entering a dehydration process. The dishwasher includes a rinsing process after performing a washing process, or drains water during draining of the next rinsing process. [0003] The above-mentioned home appliance equipped with a draining function includes a draining channel and a draining device (such as a draining pump)...
