Abstract

PURPOSE:To perform always cleaning operation for the optimum time even when water feeding temp. is changed by providing a control device for setting the operating time for continuation of cleaning after reaching a specified water temp. to be shorter as the detected water temp. is lower and longer as it is higher in accordance with the detected water temp. at the starting time of cleaning process. CONSTITUTION:Required time t1-t5 to a specified water temp. and continuously operating time of cleaning alpha1-alpha5 determined based on the cleaning power after reaching the specified water temp. having been confirmed experimentally are divided into a plurality of stages and they correspond with each other. Then, the detected water temp. at starting time of the cleaning process is divided into five stages, namely, 5 or smaller, 6-20, 21-35, 36-50 and 51 or larger and as it is lower, namely, as the required time reaching the specified water temp. t1-t5 is longer, time is set shorter and as the detected water temp. at starting time of the cleaning process is higher, namely, as the required time reaching the specified water temp. is shorter, the time is set longer. The cleaning operation is performed thereby always for the optimum time.

On the other hand, as shown in FIG. 1, the time required to reach the specified water temperature and the subsequent cleaning operation time (that is, based on the cleaning power after reaching the specified water temperature which has been experimentally confirmed in advance). (Continuous cleaning operation time determined)
By dividing the and into multiple stages to correspond to each other (in other words, the cleaning continuous operation time after the preset specified water temperature is reached is set to the lower the detected water temperature at the start of the cleaning process, that is, the specified water temperature is reached. Even if the water supply temperature changes, the longer the time required, the shorter the time, the higher the detected water temperature at the start of the cleaning process, that is, the longer the time required to reach the specified water temperature, the longer the time required.) The cleaning operation can always be performed at the optimum time, stable cleaning performance can be obtained, and excessive operation can be eliminated.
