る。Next, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front sectional view of a dishwasher to which a heating control method for washing water according to the present invention is applied. The dishwasher has a built-in washing tank 1 in which a dish basket 3 containing tableware 2 is arranged. A nozzle 4 is rotatably driven below the tableware basket 3, and a temperature sensor 5 and a heater 6 are provided in the washing tank 1.
Behind the washing tank 1, a water level detecting device 7 is provided.
Pumps 8 are provided at the lower portions of the pumps. By driving the pump 8, the washing water is blown upward through the nozzle 4, so that the tableware 2 is washed and rinsed. Reference numeral 9 denotes a control device, which receives detection signals from the temperature sensor 5 and the water level detection device 7,
Output signals are sent to the heater 6, the pump 8, a water supply / drainage device (not shown) and a motor for driving the nozzle.

It is determined whether or not the washing water has been supplied to the minimum amount that can be circulated by the pump 8, that is, 2 of the full water level. However, the value of / differs depending on the capacity and shape of the cleaning tank, the driving capability of the pump 8, and the like. When the water is supplied to 2/3 in this way, the water supply is temporarily stopped in step S4.

定温度(約40℃)に到達させることができる。Next, at step S5, the heater 6, the pump 8
By energizing the motor and raising the temperature of the washing water, the nozzle 4 is rotated, and the washing water is blown upward from the nozzle. Then, in a step S6, it is determined whether or not the set temperature (60 ° C.) has been reached. The heater 6
Since the amount of cleaning water is smaller than in the conventional heating, the temperature can reach a predetermined temperature (approximately 40 ° C.) in which the cleaning ability with the cleaning water is significantly improved in a short time.

Then, the remaining washing water is supplied, and it is determined in step S8 whether or not the water is full. If the water is full, the water supply is stopped in step S9. Then, it is determined whether or not the temperature has reached 60 ° C. again in step S10.
Washing is continued in this full state while adjusting the temperature to 0 ° C.

可能となった。Thereafter, in step S12, it is determined whether or not a predetermined time has elapsed from the start of the cleaning. At the time when the predetermined time has elapsed, the power supply to the heater 6, the pump 8, and the motor is stopped, thereby completing the process. As described above, in the dishwashing, since effective washing is performed in a state of 2/3 water supply, in the graph of FIG. 2, the conventional change (shown by a dotted line) and the change of the present application (shown by a solid line). As is apparent from the comparison with the above, it was possible to shorten the cleaning time until the completion of the cleaning in the full water state for about 5 minutes.

ぎは3回繰り返される(図3参照)。When the washing of the dishes is completed, the washing water is newly supplied and the motor and the pump 8 are driven, so that the rinsing is started. However, in this rinsing, the heater 6 is not energized, and the cleaning water is at room temperature. This normal temperature rinsing is repeated three times (see FIG. 3).

The set temperature at 1 is 70 ° C.

The time in minutes can be reduced. However, the effect of further shortening the time appears according to the number of times of high-temperature rinsing (usually performed a plurality of times).

後、前記設定温度まで昇温するようにすればよい。In the above-described embodiment, the washing water of 2/3 is heated at a stretch to the set temperature (60.degree. C. for washing). However, it is only about 40.degree. About 40 ° C (predetermined temperature)
The value should be larger than. Then, after the remaining washing water is supplied while the temperature is not lowered to about 40 ° C. or lower, the temperature may be raised to the set temperature.

Water may be supplied a plurality of times or continuously so as not to lower the temperature to 0 ° C. or lower.
【0015】さらに、前記実施例では、洗浄槽1に洗浄

1を加熱しておくようにしてもよい。Further, in the above embodiment, after the washing tank 1 is filled with the washing water, the washing water is heated by the heater 6, but the washing tank 1 is heated before the water injection as described below. You may do it.
【0016】すなわち、注水前の洗浄槽1の加熱は、図

面ヒータ10により行なう。この面ヒータ10には、例

貼着したものが採用できる。That is, heating of the cleaning tank 1 before water injection is performed by a surface heater 10 attached to an outer surface below the cleaning tank 1 as shown by a dotted line in FIG. As the surface heater 10, for example, a thin plate made of an aluminum alloy or the like and a nichrome wire or the like meandering and sticking can be used.
【0017】そして、この面ヒータ10により注水前に

た、注水中にも面ヒータ10により洗浄槽1を介して間
接的に洗浄水を加熱しておけば、従来に比べて洗浄水の
加熱を効果的に行わせることができる。If the cleaning tank 1 is preheated by the surface heater 10 before water injection, the cleaning water will not be cooled even when the temperature of the cleaning tank is lowered in winter or the like. Also, if the cleaning water is indirectly heated by the surface heater 10 via the cleaning tank 1 during the water injection, the heating of the cleaning water can be performed more effectively than in the related art.

る。Thereafter, when a full state is detected based on a detection signal from the water level detector 7, the cleaning water is directly heated by switching the energization from the surface heater 10 to the heater 6 installed in the cleaning tank 1. . This is because the total amount of current supplied to the surface heater 10 and the heater 6 is determined, and it is more efficient to directly heat the cleaning water by the heater 6.

ることが可能となる。As is apparent from the above description, according to the method for controlling the heating of the dishwasher according to the present invention, the washing water less than the optimum amount is at or above the predetermined temperature at which the washing or rinsing ability is greatly improved. By raising the temperature up to the point, the start time of the substantial cleaning or rinsing is advanced, so that the ending time of the cleaning or rinsing can be advanced even if the actual cleaning time is the same as the conventional one, Alternatively, the rinsing time can be reduced.
