Embodiment approach 1

[0021] figure 1 It is a schematic cross-sectional view of the dishwasher according to Embodiment 1 of the present invention.

[0022] Such as figure 1 As shown, the dishwasher according to this embodiment includes a washing tub 2 , a water supply unit 15 , a heater 11 as a heating unit, a thermistor 13 as a temperature detection unit, a washing unit 18 , and a control unit 16 .

[0023] The washing tub 2 is provided inside the main body 1 , and the dish basket 4 in which to-be-washed items such as dishes 3 are placed is accommodated inside the washing tub 2 . The cutlery basket 4 has an upper cutlery basket 4a and a lower cutlery basket 4b. Moreover, the opening part 5 is provided in the front surface of the washing tub 2, and the opening part 5 is comprised so that it may be opened and closed by the door body 6. As shown in FIG. Cutlery basket 4 is slidably drawn out from opening 5 of door body 6 .

[0024] Washing unit 18 has washing nozzle 7 provided at the bottom of ...

Abstract

A control unit for controlling a water feed unit, a heater, and a washing pump based on a temperature detected by a thermistor so as to carry out at least a wash water heating step and a heating / rinsing step compares the rate of temperature rise of wash water detected by the thermistor in the wash water heating step and the heating / rinsing step with each other, so as to detect the volume of a dish. In this manner, it is possible to suppress variations of the wattage of the heater or an influence by a power source voltage 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 in which the capacity such as the number or weight of dishes accommodated in the dishwasher is determined, and the operation time is controlled more finely to wash the dishes. (For example, refer to Patent Document 1) [0003] Next, use Figure 6 and Figure 7 The structure of the conventional dishwasher shown in patent document 1 is demonstrated. [0004] Figure 6 It is a figure explaining the structure of the system of the conventional dishwasher, Figure 7 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 6 As shown, the conventional dishwasher includes a washing tank 101, a washing nozzle 103, a washin...
