けている。BACKGROUND OF THE INVENTION A conventional dishwasher will be described below. As shown in the figure, a washing tank 2 is disposed inside a main body 1 of a dishwasher, and washing water in this washing tank 2 is circulated by a washing pump 3. Cleaning water is supplied into the cleaning tank 2 by a water supply device 4, the water level is detected by a water level detection device 5, and water is supplied until the set water level is reached. During washing and rinsing, the washing water pumped by the washing pump 3 is vigorously jetted from the washing nozzle 6 provided inside the washing tank 2, and collides with the tableware 8 placed in the basket 7 located above. Wash and rinse. Thereafter, the drain pump 9 is operated to discharge the cleaning water to the outside of the cleaning tank 2. The heater 10 increases the temperature of the washing water and dries the tableware 8. A control device 11 is provided to control these electrical components.

０〜７０℃ぐらいに昇温させている。[II[] In the rinsing step, the small steps of water supply, rinsing, and drainage are usually repeated 3 to 4 times. The operations of the four major processes are almost the same. First, water is supplied by the water supply device 4, the water level is detected by the water level detection device 5, and when the set water level is reached, the water supply is stopped and the cleaning pump 3 is operated. . After operating for a certain period of time or until the washing water reaches a certain temperature, the drain pump 9 is operated to discharge the washing water out of the washing tank 2. Then, in the [■] cleaning step, the heater 10 is energized to dissolve the oil and ensure cleaning performance, and in the [rV] heating rinsing step, the heater 10 is energized to improve subsequent drying. 6
The temperature is raised to about 0 to 70°C.

転方法を提供することを目的とする。Problems to be Solved by the Invention However, in the above conventional method, [II] In the washing step, the temperature of the washing water is 60 to 70°C, and the temperature of the tableware is also 60°C.
The temperature is between 0 and 70 degrees Celsius, and then, when moving to the [m] rinsing process, cold water is supplied and the washing pump is operated, and cold water is sprayed onto the warmed dishes, rapidly cooling them down. Therefore, there was a problem in that thin glass tableware could break due to thermal shock. The present invention solves the above problems and aims to provide a method of operating a dishwasher that can prevent dishes from breaking.

で制御しながら動作させる。(Left below) As shown in Table 2, first the water supply device 4 supplies cleaning water into the cleaning tank 2, and when the water level reaches a preset level, the water level detection device 5 detects this and starts water supply. , and the washing pump 3 starts operating. At the same time, energization of the heater 100 is started to raise the temperature of the cleaning water. Then, cleaning is continued for a certain period of time or until the cleaning water reaches a certain set temperature. Shortly before the end of the cleaning process, while the cleaning pump 3 is still operating, the water level detector 5 inputs a signal detected by the water level to keep the water level in the cleaning tank 2 constant, and the drain pump 9 is activated. A control device 11 controls the water supply pump 4.

る。As described above, according to this embodiment, the cleaning pump is kept running immediately before the end of the cleaning process, and the drain pump and water supply device are operated to maintain a constant water level in the cleaning tank. By replacing the cleaning water in the cleaning tank little by little, the temperature can be gradually lowered.
You can also gradually lower the temperature of the dishes. After that, even if the washing water is drained and cold water is supplied by the water supply device in the next rinsing process, the temperature of the dishes has already decreased, so there is no thermal shock applied to the dishes, preventing them from cracking. can.
