Abstract

A control unit for controlling a water feed unit, a heating unit, and a washing unit based on a detected temperature of a temperature detecting unit to execute at least a thermal capability estimating step, washing step, heating / rinsing step, and drying step compares a temperature rising-up ratio of the washing water in the thermal capability estimating step and a temperature rising-up ratio of the washing water in the washing step to detect a volume of an item to be washed and perform control. In this manner, it is possible to determine the volume of the dishes while suppressing variations of the wattage of the heater or an influence by power source voltage fluctuations in installation environment, so as to determine the volume of the dishes.

Description

technical field [0001] The present invention relates to a dishwasher for detecting the capacity of dishes and washing the dishes by detecting temperature changes of washing water. Background technique [0002] In recent years, there has been proposed a dishwasher that washes dishes while controlling the operation time more finely by judging the capacity such as the number and amount of dishes stored in the dishwasher. (For example, refer to Patent Document 1) [0003] Next, use Figure 5 and Image 6 The structure of the conventional dishwasher shown in patent document 1 is demonstrated. [0004] Figure 5 It is a figure explaining the structure of the system of the conventional dishwasher, Image 6 It is a graph showing the relationship between the power supply voltage and the temperature rise rate of a conventional dishwasher. [0005] Such as Figure 5 As shown, the conventional dishwasher includes a washing tank 101, a washing nozzle 103, a washing pump 104, a water ...
