Connected to an upper portion of connection member 256 is a pulsator rotating shaft 284. Pulsator rotating shaft 284 is fixedly inserted into first center hole 264 of pulsator 260 through second center hole 52 of blowing fan 50. In order to guide the heated air into spin tub 230, spin tub 230 is formed at its bottom wall with a perforation hole 234, and rotating plate 258 is formed with an aperture 259 which is communicated with perforation hole 234. In the washing cycle, gear assembly 250 transfers the rotational force of motor 240 to pulsator 260 through pulsator rotating shaft 284. In the dehydrating cycle, gear assembly 250 transfers the rotational force of motor 240 to spin tub 230 through connection member 256 and rotating plate 258. In addition, circulation pump 170 has a pump motor (not shown) therein and is connected to outer tub 220 through a discharging tube 172 so as to receive the washing liquid from outer tub 220. Circulation pump 170 is also connected to spraying nozzle assembly 100 through a circulation tube 176 so that the circulated washing liquid is sprayed into spin tub 230. Washing/drying machine 200 having the construction as described above operates as follows. Firstly, when a user pushes an operating switch 207 installed on upper frame 205, the washing liquid is introduced from a liquid source into outer tub 220 until a liquid level in outer tub 520 reaches a predetermined level. Then, when the liquid level in outer tub 220 reaches the predetermined liquid level, a liquid feed control valve (not shown) blocks a liquid feeding pipe, so the washing liquid stops being supplied to outer tub 220. At the same time, motor 240 rotates in the forward and reverse directions. The rotational force of motor 240 is transmitted to pulsator 260 by way of motor shaft 242, first pulley 243, belt 244, second pulley 254, gear assembly 250, and pulsator rotating shaft 284. As a result, pulsator 260 rotates in the forward and reverse directions, thereby washing the articles. At this time, blowing fan 50 which is coupled to pulsator rotating shaft 284 also rotates together with pulsator 260, thereby a strong liquid flow is created in spin tub 230. At the same time, an operating signal is transmitted to the pump motor accommodated in circulation pump 170 in accordance with a predetermined algorithm so that the pump motor rotates in the forward direction. When the pump motor rotates in the forward direction, a first valve disposed between circulation pump 170 and circulation tube 176 is opened and a second valve disposed between circulation pump 170 and drain tube 174 is closed. In addition, as the pump motor operates, circulation pump 170 also operates, so that some of the washing liquid that has been introduced into outer tub 220 is discharged from outer tub 220 into circulation pump 170 through discharging tube 172. Upon receiving the washing liquid, circulation pump 170 compresses the washing liquid and circulates the washing liquid through circulation tube 176 into spraying nozzle assembly 100 mounted on the upper portion of outer tub 220. Spraying nozzle assembly 100 strongly sprays the compressed washing liquid onto the articles, so that the washing efficiency is improved without wasting any washing liquid. When the washing cycle has finished, the pump motor rotates in the reverse direction. At this time, the first valve disposed between circulation pump 170 and circulation pump 176 is closed, and the second valve disposed between circulation pump 170 and drain tube 174 is opened.
Accordingly, the washing liquid filled in outer tub 220 is drained out of washing/drying machine 200 by way of discharging tube 172, circulation pump 170, and drain tube 174. Then, the dehydrating cycle begins. While the dehydrating cycle is being executed, the articles placed in spin tub 230 are forced towards the side wall of spin tub 230 due to a centrifugal force applied thereto, so the washing liquid contained in the articles is drained out of washing/drying machine 200 through discharging holes 232.
When the dehydrating cycle has finished, a microcomputer accommodated in washing/drying machine 200 sends operating signals to blower 180 and heater 190 disposed within air guide 150. At the same time, the microcomputer sends an operating signal to motor 240 so as to rotate blowing fan 50. As a result, the air is introduced into air guide 150 from the exterior of washing/drying machine 200 through first air inlet 209 and second air inlet 160. Then, the air which has been introduced into air guide 150 is heated while it passes through heater 190, and, as shown by an arrow 175 in
The scope of the present invention relates to washing/drying appliances. The present invention has been made to overcome the above described problems of the prior arts, and accordingly, it is an object of the present invention to provide a washing/drying machine which comprises an pulsator arranged within an predetermine region of the inner cabinet which comprises an plurality of spring induction holes and spring induction caps which may be used to allocate the pulsator to marginally flex downwardly to apply an force upon the load capacity sensing apparatus for sensing the load capacity of articles stored within the inner drum portion thereby providing an more precise solution to determine the load capacity of articles within the inner drum. The appliance may further comprise an plurality of motor(s) (e.g., DC motors) coupled within an predetermine region of the inner cabinet and the outer drum envisioned to raise/lower the outer drum to and from the load capacity sensing apparatus to obtain load capacity data depending on one mode of the appliance. For instance, when an user selects load capacity sensing mode the appliance controller sends an signal to the motor(s) to rotate at an predetermine direction in response lowering the outer drum onto the load capacity sensing apparatus, further the load capacity sensing apparatus transmits an return signal to the appliance controller reveling the sensed outer drum load capacity (e.g., weight) which is further shown on the appliance display. Further, when the user chooses to opt out of load capacity sensing mode the appliance controller distributes an signal to the motor(s) to rotate at an predetermine direction in response raising the outer drum from the load capacity sensing apparatus. In conclusion, the present invention provide a solution that overcomes the shortcomings of determining the load capacity of articles that are stored within the inner drum of an appliance.
