The present invention relates to a multifunctional control device for water supply administration of a dishwasher, and to provide various functions of supplying water required for dishwashing and supplying an accurate quantity.

In general, when the water supply administration of the dishwasher does not supply water from the water supply valve, water supply failure due to excessive water supply or leakage, or heating water with a heater, malfunction of the heater or overheating is not detected properly. Frequent breakdowns in the use of the dishwasher caused inconvenience.

In order to solve the above problems, the present invention checks the state of water supply and hot water supply necessary for washing, and informs whether there is high water. When water supply is not available at the time of water supply, the water supply valve 80 and the operating level pressure SW ( 50 is detected, the overflow pressure SW 60 and the leakage SW 70 detects this when the water supply is over, the drain pump 40 detects the abnormal water level, the overheat prevention device 90 and the thermistor 100 ) Is to detect the hot water overheating or malfunction of the heater to shut off the main power.

The drainage pump 40 for detecting abnormal water level and draining the water in the dishwasher, the operating level pressure SW 50 for controlling the amount of water supplied by the peak level, and the operating level pressure SW 50 at the time of water supply. When excessive water is supplied due to failure or other factors, it detects this to cut off the supply of water, and detects an overflow pressure SW 60 for operating the drain pump 40 and a leak occurring outside the sump during water supply. Leakage SW 70 to prevent safety accidents, such as a short circuit, overheat due to a malfunction of a heater operated for hot water supply, and overheat prevention device 90 for shutting off the main power when the set temperature is over, and supplied water When the temperature is higher than the set temperature it is configured as a demister (100) to cut off the power, the door SW (20) for detecting the opening and closing of the door of the dishwasher, and the incoming water to wash the discharge pressure of the pump · The water spray pump 30 to the lower rotor is additionally connected to the MICOM.

When explaining the effect of the present invention in detail based on the accompanying drawings as follows.

FIG. 1 is a block diagram of the present invention to control devices having respective functions by MICOM, and to input and output information required for administration of the dishwasher. The drain pump 40 operates when the abnormal water level is detected to drain the water in the dishwasher, and the operating level pressure SW 50 controls the amount of water at the time of water supply by the peak water level, and the overflow pressure SW 60 is When excessive water is supplied by the failure or other factors of the operating level pressure SW (50) at the time of water supply, it detects this to cut off the supply of water and operates the drainage pump (40) to drain. In addition, the leakage SW (70) detects the occurrence of water leakage to the outside of the collection tank during water supply to prevent safety issues such as short circuit, and the water supply valve 80 supplies water into the collection tank by the action of the solenoid, The overheat prevention device 90 cuts off the main power when the heater malfunctions when the water supply for hot water washing is overheated and exceeds the set temperature, and the demister 100 detects this when the temperature exceeds the set temperature when the hot water is supplied. Will be blocked.

The function of the above control device is to supply water when the water supply valve 80 is operated when water is not supplied to the water collection tank as shown in FIG. 2, and water supply starts when water supply valve 80 is broken or water supply flow path is blocked. After 5 minutes, if the operating level pressure SW (50) is not operated, after 3 minutes of drainage, the power off and the SVC Call alarm is generated as an alarm sound. If it is not the case or if the operating level pressure SW (50) is operating, continue to supply water.

In addition, in the functional diagram of FIG. 3, if the water supply is excessive, it is determined whether the water supply valve 80 is faulty at the time of water supply, and if it is a failure, whether the overflow pressure SW 60 is operated after the operation level pressure SW 50 is operated. When it is recognized and operated, after 3 minutes draining, power off and service call alarm is sounded to generate an alarm sound.If it does not work, water supply is operated by operating level pressure SW (50) and overflow pressure SW (60) after 5 minutes of water supply. Exit the state.

On the other hand, if the water supply valve 80 is not a failure, it is determined whether the operating level pressure SW (50) is a failure, and if it is a failure, it is determined whether the overflow pressure SW (60) operation without the operation level pressure SW (50) operation If it is activated, the water supply is terminated. If it is not operated, the overflow pressure SW (60) is broken.Therefore, since the operating level pressure SW (50) and the overflow pressure SW (60) do not operate five minutes after the water supply, After draining for 3 minutes, the power is turned off and a service call alarm sounds. If the operating level pressure SW (50) is not a malfunction, determine the leak state, if no leak is detected, after 5 minutes of water supply, the operating level pressure SW (50) and the overflow pressure SW (60) is inoperative to alarm with a service call alarm If a leak is detected, the leakage SW 70 is operated to stop the operation.

4 is a function diagram when the water is to be supplied to the hot water when the heater malfunctions and overheats when the overheat protection device (90) is activated to sound a service call alarm to sound, if the overheat protection device (90) does not operate The thermistor 100 operates to detect overheating, cut off the main power, and generate an alarm sound through a service call alarm to recognize the user.

As such, it is to provide convenience in using the dishwasher by providing various functions such as supplying accurate water and hot water at the time of water supply administration.

Claims (1)

In the dishwasher having a water supply administration function, the drainage pump 40 for draining the water in the dishwasher by detecting the abnormal water level, the operating level pressure SW (50) for controlling the amount of water supplied by the peak water level, When excessive water is supplied due to breakdown of operating level pressure SW (50) or other factors at the time, it detects this and cuts off the supply of water and operates drain pump (40), and water tank at water supply It prevents overheating to cut off the main power when it is overheated due to the malfunction of the leakage SW 70 and the heater operated to supply hot water to detect the leakage of water and prevent safety accidents such as electric leakage.
