The present invention relates to a multiple solenoid valve.

In general, a washing machine for washing clothes has a solenoid valve for supplying washing water into a washing tank. The solenoid valve connects a hose to a faucet, and then opens the faucet. The valve unit is automatically opened and closed by a microcomputer of the controller. The washing water is supplied to the washing tank at an appropriate level, and washing, drainage, and rinsing are performed to wash the clothes.

Recently, when washing machines and detergents are put into a washing tank, a general washing machine automatically supplies a certain amount of hot water and cold water into the washing tank according to the amount of laundry, and then a washing drum, a washing plate, or a rod is rotated by a motor to generate strong water flow. As a result, washing is performed by the current and impact action of the washing water in which the detergent is dissolved.

Solenoid valve for automatically supplying the hot water and cold water in the washing tank in the conventional washing machine to match the water temperature set in the washing is performed as shown in Figure 1, the water inlet for hot or cold water flows through the faucet and hose (2) ) And a body (1) having an inlet (3) through which the hot water or cold water is supplied into the washing tank through the water inlet (2), and through the water inlet (2) and the inlet (3) to the body (1). The valve unit (4) for selectively opening and closing the hot or cold water supplied in the controller in the microcomputer is installed.

The valve unit 4 having a function of selectively opening and closing hot or cold water in a solenoid valve having such a structure is a general solenoid operation method, in which hot water or cold water is supplied by operating a valve by suction force of an electromagnet generated by supplying power to a coil. It is installed to open and close the flow path supplied to the inlet (3) through (2).

The solenoid valve is provided with a water inlet according to hot water or cold water, where the solenoid valve for supplying cold water is generally installed with a plurality of inlets and valve units to perform a washing process by selectively converting the flow path of the cold water supply Meanwhile, the set water temperature is adjusted.
