Abstract

PURPOSE:To prevent the leaving of a meal from being left on the bottom surface of a washing tank and to improve a rate to receive the residue of the meal into a filter by starting the operation of a pump for draining before the operation of a pump for washing is stopped. CONSTITUTION:When washing and rinsing processes are operated, the residue of the meal stuck to dishes are put off by the washing and draining output of a pump 2 for washing and the residue of the meal is received to a filter 4 provided on the adsorbing port part high order of the pump 2 for washing, by the attracting force of the pump 2 for washing. Before the washing and rinsing processes are finished, the operation of a pump 3 for draining is started. Thus, the since washing water and rinsing water in a washing tank 1 is drained out of a dish-washing machine while the residue of the meal, which is once received in the filter 4, are received in the filter 4 by the attracting force of the pump 2 for washing, the residue of the meal can be prevented from being dispersed in the washing tank 1. Thus, the residue of the meal to be received in the filter 4 can be securely collected without being dispersed in the washing tank and pollution degree in the washing tank can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of operating a dishwasher equipped with a wash pump and a drain pump.

BACKGROUND OF THE INVENTION The structure of a conventional dishwasher is shown in FIG. As shown in Figure 3, there is a washing pump 2 for washing or rinsing the dishes stored in the washing tank 1, and the washing water and rinsing water remaining in the washing tank 1 after washing or rinsing. Drainage pot 3 for forcibly draining water out of the cleaning tank 1
It is equipped with

The control of each pump 2 and 3 is as shown in FIG.
Operating the cleaning pump 2 in the cleaning or rinsing process,
At the end of each process, after the cleaning pump 2 stops operating, the drainage pump 3 starts operating after t' time, and the cleaning water and rinsing water in the cleaning tank 1 is drained outside the cleaning tank 1. Was.

Problems to be Solved by the Invention However, in the conventional configuration, as shown in FIG. 3, a filter 4 provided above the suction port of the washing pump 2 is used to store leftover food adhering to the surface of the dishes. In the machine, the leftover food stored in the filter 4 by the suction power of the washing pump 2 during the washing or rinsing process is transferred to the washing pump 2 at the end of each process and when the washing pump 2 is stopped.
Due to the reaction of the suction force, it will be diffused from the filter 4 to the entire cleaning tank 1 along with the cleaning water or rinsing water.
In particular, leftover food with a low specific gravity floats on the surface of the washing water, and even when the drainage pump 3 starts operating, the leftover food cannot be stored in the filter 4 and remains at the bottom of the washing tank 1.
The storage rate of leftover food in the cleaning tank 1 decreases, and the degree of contamination of the cleaning tank 1 increases. Also, wash.

A device in which the heater 6 is energized after the rinsing step to operate the drying step has a problem in that as the temperature inside the washing tank 1 rises, the leftover food that has spread to the bottom of the washing tank 1 generates a musty odor. Ta.

In view of the above problems, an object of the present invention is to improve the storage rate of leftovers in a filter without leaving any leftovers on the bottom of the cleaning tank.

Means for Solving the Problems In order to achieve the above object, the present invention starts the operation of the drainage pump before the operation of the cleaning pump stops.

Effect According to the above operating method, by starting the operation of the drainage pump before the operation of the washing pump stops, the leftover food stored in the filter is washed away by the suction force of the washing pump while the washing pump is operating. By operating the cleaning pump and the drainage pump at the same time, the suction power of the cleaning pump allows drainage to be stored in the filter and drained outside the product machine. When the process is finished, the leftover food will definitely be stored in the filter.

As you can see from the above explanation, by draining the water while storing leftovers in the filter using the suction power of the cleaning pump, the leftovers are reliably stored in the filter and the degree of contamination on the bottom of the cleaning tank is reduced. This makes it possible to reduce the amount of water used.

Example An embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a dishwashing machine according to an embodiment of the present invention.

It is a figure which shows a rinsing process, and the structure of a dishwasher is the same as a conventional structure. Therefore, each step will be explained below with reference to FIG. 1. That is, in each washing and rinsing process, the washing pump 2 is operated to wash or rinse the dishes, and the drain pump 2 is operated to forcefully drain the washing water and rinsing water outside the product machine. However, when the cleaning and rinsing steps are completed, the drainage pump 3 is started operating before the cleaning pump 2 stops operating (time t shown in FIG. 1).

That is, before the cleaning and rinsing steps are completed, the cleaning pump and the drainage pump are operated simultaneously for t hours.

When operating the washing, washing and rinsing processes according to the above operating method,
The cleaning discharge force of the cleaning pump 2 removes leftovers adhering to the dishes, and the suction force of the cleaning pump 2 stores the leftovers in a filter 4 provided above the suction port of the cleaning pump 2.

By starting the 4-turn operation of the drain pump 3 before the washing and rinsing processes are completed, the leftover food once stored in the filter 4 remains stored in the filter 4 due to the suction power of the washing pump 2, and is transferred to the washing tank 1. Washing water inside.

Since the rinsing water is drained outside the product machine, it is possible to prevent leftovers from spreading into the washing tank 1.

Effects of the Invention As is clear from the above embodiments, according to the present invention, since the drainage pump starts operating before the cleaning pump stops, the suction power of the cleaning pump drains the leftovers stored in the filter. This makes it possible to reliably collect the waste without dispersing it into the cleaning tank, and it becomes possible to reduce the degree of contamination in the cleaning tank as much as possible.

In addition, it is possible to reduce the odor generated in the washing tank due to leftovers. Especially in dishwashers where the heat source is exposed in the washing tank, it is possible to prevent odor caused by leftovers adhering to the heat source and to remove leftovers. It is also possible to improve product safety, such as by preventing smoke generation.
