Abstract

PURPOSE: To improve safety by performing a blasting operation before a hot water rinsing process is completed in a tableware washer/drier containing a heat blasting unit, a washer tub, a circulating pump, a controller and a temperature detector to lower steam temperature discharged in drying. CONSTITUTION: When tablewares are arranged in an upper basket 11 and a lower basket 12 and cleanser is thrown in a cleanser throw-in port and a door 3 is closed, water is supplied up to a regulated water level, and a washing pump motor is operated simultaneously with the start of a heater unit 19. Then, pressurized water is injected from the small holes 13a, 13b of upper and lower nozzles 14, 16, and regular rinsing process is started. Thence, after a rinsing process is performed, the hot water rinsing process is performed while heating water up to regulated temperature. When temperature reaches set temperature for starting the blasting operation, the blasting operation is performed, and steam in the washing tub 7 is discharged from an exhaust port 25a to an exhaust port 25b. After that, when temperature reaches the regulated temperature, the hot water rinsing process is completed, then, a discharge process and a drying process are started.

Next, the operation of the dishwasher and the temperature change in the washing tank 7 in the standard cycle operation will be described with reference to FIG. The tableware is placed in the upper basket 11 and the lower basket 12, the detergent is put into the detergent inlet (not shown), the door 3 is closed, and the operation is started by the operation button. When the water is supplied to the specified water level, the heater unit 19 is energized and at the same time, the washing pump motor (not shown) is operated. Pressurized water is lower nozzle 1
6 and the small holes 13a of the upper nozzle 14, at the same time, the reaction force of the injection is received and rotation is started. The number of revolutions is about 20 revolutions per minute, and the dishes in the washing tank 7 are evenly exposed to the washing water, and the water temperature gradually rises to about 50 ° C. Therefore, the action of the jetting force, the warm water, and the detergent causes the dishes to be washed. Perform the "main washing" process to remove the dirt. Next, a "rinsing" step is performed. Next, a "warm water rinsing" step is performed while heating to a prescribed water temperature of about 70 ° C. When the temperature of the blowing operation start temperature T 2 60 ° C is reached, the blowing operation is performed and the steam in the cleaning tank 7 is exhausted from the exhaust port 25a. It is discharged to the exhaust port 25b through the valve 26. When the prescribed water temperature reaches about 70 ° C., the “warm water rinsing” step is finished, the “drainage” step and the “drying” step are started, and the operation is finished after a certain time.

The exhaust temperature of the exhaust port 25b having the above structure and control will be described with reference to FIG. When the hot water rinsing temperature is set to the water temperature T 1 of about 70 ° C. and the blowing operation is performed, the high temperature steam of about 65 ° C., which is close to about 70 ° C., is initially discharged. It can be seen from the graph that the exhaust temperature also drops when the airflow start temperature is lowered. Therefore, it is necessary to operate the air blowing start temperature earlier than the end of the "warm water rinsing" process, but if the air blowing start temperature is made faster, it will take time to reach the end temperature setting of the "hot water rinsing" process, resulting in a cycle time decrease. Make it long. Thus the relationship cycle time and the exhaust gas temperature, "hot rinse" Exit set temperature T 1 of about 70 ° C. than the blowing operation start temperature T 2 is T 1 -10 ° C.
Is the most effective, and it is possible to set the exhaust temperature with excellent safety without the anxiety of burns even when approaching the exhaust port.
