Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator for supplying cold water in which its structure is simple, its manufacturing cost is low and a periodic maintenance of a water purifying device can be easily performed even by a user by a method wherein an increasing of hydraulic pressure in a pipe of the refrigerator is restricted. SOLUTION: This refrigerator is comprised of a tank 5 within a refrigerator, a water supply valve 11 arranged at the midway part of a water supplying pipe to which tap water is connected, a water extracting means 9 for discharging cold water, a purified water processing device 4 arranged in the midway part of a pipe for use in connecting the tank 5 with the water taking means 9 and a water taking valve 10. In this case, when cold water is supplied, at first the water taking valve 10 is opened, and then the water supplying valve 11 is controlled to open, thereby water pressure of tap water is not applied to the pipe in the refrigerator as it is and so an increasing in hydraulic pressure in the pipe can be restricted and so any special pressure design can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To maintain the better operating condition of a motor by eliminating a problem that the operating condition of a load becomes unstable when a voltage applied to the load is changed with a switch in a refrigerator. SOLUTION: When it is required to change the speed of the motor 25, the rotating speed of motor 25 is varied up to an intermediate speed which is the suitable rotating speed for changing the application voltage to a power module 24 for the load, and the voltage is changed after changing the rotating speed. Thereafter, rotating speed of motor is varied up to the target rotating speed. As a result, shortage of lubrication oil of the motor 25 can be avoided and low noise operation of motor can also be realized.
