る。However, as described above, since the cleaning water is heated up to the optimum amount at a stretch, the temperature is raised to a temperature (about 40 ° C.) at which the desired cleaning ability can be exerted. It takes time to heat the wash water. Therefore, the cleaning or rinsing cannot be performed efficiently, and the cleaning time or the rinsing time becomes long. In particular, when rinsing is performed a plurality of times (usually a plurality of times), the problem becomes remarkable. In view of the above problems, it is an object of the present invention to provide a washing water heating control method for a dishwasher, which can shorten the washing and rinsing time.

る。Embodiments of the present invention will now 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 dish washing machine has a washing tank 1 built therein, and a dish basket 3 accommodating the dishes 2 is disposed inside the washing tank 1. A nozzle 4 is rotatably provided below the tableware basket 3, and a temperature sensor 5 and a heater 6 are provided in the cleaning tank 1.
Further, behind the cleaning tank 1, a water level detecting device 7 is provided.
Pumps 8 are provided in the lower portions of the respective. Then, by driving the pump 8, the washing water is blown upward through the nozzle 4 so that the dishes 2 are washed and rinsed. A control device 9 receives detection signals from the temperature sensor 5 and the water level detection device 7,
Output signals are issued to the heater 6, the pump 8, a water supply / drainage device (not shown), and a motor for driving the nozzle.

給水を停止する。Here, heating control of the washing water by the dishwasher will be described with reference to the graphs of FIGS. 2 and 3 and the flowchart of FIG. As shown in FIG. 4, in dishwashing, when the power is turned on in step S1, water supply is started in step S2. Then, in step S3,
It is determined whether or not the minimum amount of wash water that can be circulated by the pump 8, that is, 2/3 of full water has been supplied. However, this value of 2/3 is different depending on the capacity and shape of the cleaning tank, the driving capacity of the pump 8, and the like. When the water is supplied to 2/3 in this way, the water supply is once stopped in step S4.

Also, the washing water is heated by energizing the motor, and the nozzle 4 is rotated to blow the washing water upward from the nozzle. Then, in step S6, it is determined whether or not the temperature has reached 60 ° C. Since the amount of cleaning water used in the heating by the heater 5 is smaller than that in the conventional case, it takes 6 seconds in a short time.
The temperature can be raised to 0 ° C., and the desired cleaning ability can be exhibited early.

In step S8, it is determined whether or not the water is full, and in step S8, the water supply is stopped in step S9. Then, in step S10, it is judged again whether or not the temperature reaches 60 ° C., and if it reaches 60 ° C. in step S11.
The washing is continued under the full water condition while controlling the temperature to 0 ° C.

水状態での洗浄時間を短かくすることが可能となった。Thereafter, in step S12, it is determined whether or not a predetermined time has elapsed from the start of cleaning, and when the time has elapsed, the heater 6, the pump 8 and the motor are deenergized to complete the process. As described above, in the dishwashing, the effective washing is performed in the state of supplying 2/3 of the water, and therefore the conventional change (shown by a dotted line) and the change of the present application (shown by a solid line) in the graph of FIG. As is clear from the comparison with the above, it became possible to shorten the cleaning time in a full water state by about 5 minutes.

ぎは３回繰り返される（図３参照）。When the dishwashing is completed, washing water is newly supplied to drive the motor and the pump 8 to start rinsing. However, in this rinsing, the heater 5 is not energized and the cleaning water is kept at room temperature. This room temperature rinsing is repeated three times (see FIG. 3).

１での設定温度は７０℃とされている。When the room temperature rinsing is completed, high temperature rinsing is performed. This high-temperature rinsing is performed according to the flow chart of FIG. 4, as in the case of the dishwashing. However, in the flowchart, steps S6, S10 and S1
The set temperature at 1 is 70 ° C.

短縮の効果が現れる。As described above, even in the case of high temperature rinsing, the desired cleaning ability can be exhibited as early as in the case of the dishwashing, and the rinsing time can be shortened by about 5 minutes. It is possible to shorten the minutes. However, the effect of further shortening the time appears depending on the number of times of high temperature rinsing (usually performed a plurality of times).
【００１３】なお、前記実施例では、２／３の洗浄水を

で昇温するようにすればよい。In the above embodiment, 2/3 of the washing water is heated up to the desired temperature (60 ° C. in washing) at once, but the washing ability is remarkably improved at about 40 ° C. Since it is known, any value above this temperature may be used. Then, after the remaining cleaning water is supplied while preventing the temperature from lowering to 40 ° C. or lower, the temperature may be raised to the desired temperature.
【００１４】また、前記実施例では、２／３の洗浄水が

行わせるようにしてもよい。Further, in the above-mentioned embodiment, when the 2/3 of the wash water reaches the desired temperature, the remaining wash water is supplied all at once. Water may be supplied a plurality of times or continuously so as not to decrease.
【００１５】さらに、前記実施例では、洗浄槽１に洗浄
水を満水状態とした後、ヒータ６でこの洗浄水を加熱す
るようにしたが、下記するようにして注水前から洗浄槽
１を加熱しておくようにしてもよい。Further, in the above-mentioned embodiment, after the cleaning water is filled in the cleaning tank 1, the cleaning water is heated by the heater 6, but the cleaning tank 1 is heated before the water injection as described below. You may keep 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, the heating of the cleaning tank 1 before water injection is performed by the surface heater 10 attached to the outer surface below the cleaning tank 1 as shown by the dotted line in FIG. As the surface heater 10, for example, a thin plate made of an aluminum alloy or the like in which a nichrome wire or the like is meandered and adhered can be adopted.
【００１７】そして、この面ヒータ１０により注水前に

している場合でも、洗浄水が冷却されることはない。ま
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 pouring water, the cleaning water will not be cooled even when the temperature of the cleaning tank is lowered in winter or the like. Further, if the cleaning water is indirectly heated by the surface heater 10 via the cleaning tank 1 even when pouring water, the cleaning water can be heated more effectively than before.

る。After that, when the full water state is detected based on the detection signal from the water level detection device 7, the surface heater 10 switches the power supply to the heater 6 installed in the cleaning tank 1 to directly heat the cleaning water. . This is because the total energization amount of the surface heater 10 and the heater 6 is fixed, and it is more efficient to heat the cleaning water directly by the heater 6.

Since cleaning and rinsing are performed, effective cleaning and rinsing can be performed early and the cleaning and rinsing time can be shortened.
