The present invention relates to a multifunctional control device for sprinkling operation of a dishwasher, and to provide various functions for washing dishes by supplying washing water to the upper rotating body and the lower rotating body by the spraying pump. .

In general, the water supplied into the dishwasher is supplied to the upper and lower rotors through the spray pump to wash the dishes, and water is sprayed. When water is sprayed, leakage or water leakage occurs due to foaming or leakage. There was an inherent danger of a safety accident due to overheating when washing water was excessively heated or the washing water was heated to spray hot water because it could not detect the proper amount of water into the room.

In order to solve the above problems, it is necessary to detect the proper level of the operating level pressure SW (50) and the overflow pressure SW (60) due to the malfunction of the operating level pressure SW (50) due to the function of the sprinkling stroke of the dishwasher. When the water level is abnormal, it detects this and cuts off the water supply.The leak SW 70 detects a leak such as overflow of water out of the water tank and diversifies the function of using the dishwasher. .

Using the discharge pressure of the pump, the water flowed into the collection chamber of the dishwasher, the sprinkling pump 30 for washing by sending to the upper and lower rotary bodies, and the operating level pressure SW (50) for detecting the appropriate amount of water supplied to the water. And overflow pressure SW (60) for detecting water when water level is abnormal due to malfunction or other factors of the operating level pressure SW (50), and blocking water supply, and collecting water during the watering for cleaning. It consists of a leakage SW (70) for detecting the overflow of water due to the excessive occurrence or leakage occurs due to other causes, the door SW (20) for detecting the opening and closing of the door, the drain pump 40 for draining the residual water, etc. And a water supply valve 80 for supplying water for cleaning was additionally connected.

The present invention is described in detail based on the effect of the accompanying drawings as follows.

FIG. 1 is a block diagram of the present invention, and the MICOM controls devices having respective functions or inputs and outputs information necessary for the administration of the dishwasher.

2 is a functional diagram showing an embodiment of the present invention when the water supply valve 80 is operated to operate the operating level pressure SW 50 for detecting the water level, the power supply of the water supply valve 80 is turned off (OFF) The operation of the valve 80 is stopped.

When the water supply valve 80 is continuously operated by determining whether the power supply valve 80 is turned off, the water supply pump 30 and the overflow pressure SW 60 are detected and operated after draining for 3 minutes. If all the power is turned off and the service call (SVE CALL) alarm is alarmed, and the watering pump 30 and the water supply valve 80 are not operated, the leakage SW 70 is activated and the operation is not activated. When the alarm sounds and the alarm is activated, the dishwasher is stopped.

On the other hand, if the power of the water supply valve 80 is not supplied, the watering pump 30 is operated and controlled, and after the set time to perform the next planet, the operation is stopped when the operation time is operated over the set time. .

As such, in the present invention, the operation of the water spray pump 30 during the water spraying operation is carried out to detect the water level of the operating level pressure SW 50, the abnormal water level sensing action of the overflow pressure SW 60, and the leakage sensing action of the leakage SW 70. Due to this has given a variety of functions on the dishwasher use.

Claims (1)

In the dishwasher having a sprinkling stroke function, the sprinkling pump (30) for washing the water flowing into the water collecting chamber by using the discharge pressure of the pump to the upper and lower parts of the whole, and the operation to detect the appropriate amount of water supplied Level pressure SW (50), overflow pressure SW (50) for detecting water when water level is abnormal due to malfunction or other factors of operating level pressure SW (50) and blocking water supply, and water for cleaning Multifunctional control device for sprinkling operation of the dishwasher, characterized in that the leakage SW (70) for detecting that the water overflow or other leakage caused by other factors caused by excessive foaming out of the sump.
