Description

How to set the drying temperature of your dishwasher

The present invention relates to a method for setting a drying temperature of a dishwasher, and in particular, after sensing a drying stroke which is carried out after a series of washing and rinsing strokes is completed, setting the drying temperature according to the detected outside temperature. By drying, it relates to a drying temperature setting method of the dishwasher to reduce unnecessary power consumption.

In general, when the dishwasher is supplied with power in a state where the dish is to be placed in the washing room, the dishwasher supplies water to the washing room at a predetermined level and supplies the washing water supplied while the heater is driven to a predetermined temperature. ℃ -75 ℃), and driving the pump to discharge the heated washing water with the injection nozzle while suction pumping to separate and wash the food residue on the dishes placed in the washing chamber through the injection nozzle, When the washing is completed, the cold water is supplied to a predetermined level and then rinsed. When the rinsing is completed, the cold water is supplied to a predetermined level, the heater is driven, and the supplied washing water is heated and drained to a predetermined temperature. The fan is operated to inhale the outside air and dry the dishes which have been washed by latent heat.

In this process of washing, rinsing and drying as a series of washing operations, the conventional drying method is to heat and dry the heater to a predetermined heating temperature while neglecting the room temperature.

However, the drying method of the dishwasher is to dry by heat suction and dissipation action by the temperature difference between the temperature of the outside air and the heating temperature, for example, when the difference between the outside air temperature and the heated drying temperature is small, the heat suction and dissipation action is small. When the drying efficiency is lowered, on the other hand, when the difference between the outside temperature and the heated drying temperature is large, there is a problem in that power is unnecessarily wasted as compared to the drying efficiency.

Nevertheless, the dishwasher is designed to dry with latent heat by a predetermined heating temperature without considering the external air temperature during drying, so that the outside air temperature and heated drying due to the climate difference at times of extreme cold or cold and season change The temperature and the temperature difference is less generated or the temperature difference is generated largely, the drying efficiency is lowered or needlessly consumes a lot of power.

An object of the present invention is to dry while maintaining the difference between the outside temperature and the heated drying temperature and the appropriate temperature during the drying stroke after a series of washing, washing and rinsing stroke, thereby improving drying efficiency and preventing unnecessary waste of power. I want to be.

In order to realize the above object, the present invention provides a series of washing strokes in the washing, rinsing, and drying strokes to supply water in the drying stroke after completion of the rinsing stroke, and to sense whether the detected outside temperature is below a predetermined temperature by sensing the outside temperature. Judging by setting the heating temperature in accordance with the determined temperature characterized in that the drying is performed while heating the wash water to the set heating temperature.
