Definitions

  • the present invention relates to a washer having a drum with improved mobility.
  • washers In washers such as a washing machine, washing is performed by the chemical washing effect provided by a detergent, and physical or in other terms the mechanical washing effect generated by the items to be washed rubbing against each other.
  • the washer producers conduct research for enhancing the mechanical washing effect.
  • washers are known in the art in which a drum in which washing is performed, is moved preferably in vertical and horizontal directions as well as being rotated about itself. Items to washed are enabled to be added into the drum after washing starts, thanks to moving the water in the drum away from the loading opening by moving the drum so as to be inclined from the loading opening to the rear wall of the drum.
  • the items to be washed being heavy exact the motion mechanism enabling the drum to oscillate.
  • the desired washing quality cannot be achieved when the drum is loaded with a high amount of items to be washed.
  • the vibration of the washer as well as the noise it emits increases by oscillation.
  • EP3034668 discloses a washer having a drum vertically movable in up-down direction when not rotating.
  • the aim of the present invention is to realize a washer wherein useful lifetime of the motion mechanism enabling increasing the mobility of the drum is increased and the mechanical washing effect is enhanced.
  • the washer realized to achieve the aim of the present invention and disclosed in the claims, comprises a control unit controlling the motion mechanism enabling oscillation motion in a direction other than the rotation direction of the drum in which the items to be washed are washed, and determining the duration and/or the frequency of the oscillation motion of the drum so as to be proportional to the amount of load in the drum.
  • the control unit enables the drum to be driven in a low frequency when the drum is loaded for the motion mechanism delivering oscillation motion to the drum, not to be overworked, and in a high frequency when the drum is underloaded.
  • control unit also enables the drum to be oscillated for a longer duration for better washing the items to be washed when the drum is loaded and for a shorter duration when the drum is underloaded.
  • the useful lifetime of the motion mechanism is enhanced by operating the motion mechanism for a shorter duration when the drum is underloaded, and by driving the drum in a lower frequency when it is loaded, and the washing efficiency is not compromised by driving the drum in a higher frequency when it is underloaded, and operating the motion mechanism for a longer duration when the drum is overloaded.
  • the motion mechanism if the load amount is higher than a predetermined limit load amount, then the motion mechanism is operated for a longer duration and/or driven in a lower frequency. Likewise, in other embodiments of the invention, if the load amount is lower than a predetermined limit load amount, then the motion mechanism is operated for a shorter duration and/or driven in a higher frequency.
  • control unit determines the duration of oscillation motion in direct proportion to the load amount. A separate motion duration is determined for each load amount.
  • the maximum and the minimum motion durations are recorded in the memory of the control unit, and the motion duration is determined in direct proportion to the load amount so as to be between the maximum duration and the minimum duration.
  • control unit determines the frequency of oscillation motion in inverse proportion to the load amount.
  • a separate motion frequency is determined for each load amount.
  • the maximum and the minimum motion frequencies are recorded in the memory of the control unit, and the motion frequency is determined in inverse proportion to the load amount so as to be between the maximum frequency and the minimum frequency.
  • control unit determines the load amount in the drum using the amount of water received into the drum. As the amount and therefore the weight of the items to be washed added to the drum increase, the items to be washed draw more water and more water is received into the drum. The control unit calculates the load amount using the amount of water received into the drum without an external weight sensor.
  • the control unit when the amount of water in the drum exceeds a predetermined level, transmits a signal to the motion mechanism to reduce the amplitude of oscillation motion, thereby preventing the water in the drum from overflowing and leaking out.
  • the amplitude is prevented from further increasing by the oscillation of water in the drum resonating with the oscillation motion of the drum.
  • items to be washed can be added without overflowing of water in the drum, by the control unit increasing the motion amplitude provided by the motion mechanism.
  • the control unit increasing the motion amplitude provided by the motion mechanism.
  • the oscillation motion of the drum is performed without overworking the motion mechanism and without compromising the washing efficiency by means of the control unit controlling according to load amount.
  • the control unit controlling according to load amount.
  • the washer is enabled to vibrate less and the noise is thus prevented from increasing.
  • Figure 1 is a schematic view of a washer.
  • Figure 2 is a diagram of the changes in the duration of motion and the motion frequency relative to the load amount, in different embodiments of the invention.
  • Figure 3 is a diagram of the changes in the duration of motion and the motion frequency according to the load amount, in different embodiments of the invention.
  • the washer (1) comprises a body (2), a drum (3) provided in the body (2), in which the items to be washed are placed, and a motion mechanism (4) enabling the drum (3) to oscillate in a direction other then the rotation direction about itself.
  • the washer (1) of the invention comprises a control unit (5) determining the duration (t) and/or the frequency (f) of the oscillation motion of the drum (3) in at least one different direction according to the load amount (W) in the drum (3), by controlling the motion mechanism (4).
  • the control unit (5) determines the duration (t) and/or the frequency (f) of the oscillation motion of the drum (3) proportionally to the load amount (W).
  • the load amount (W) is high, the drum (3) is oscillated for a longer duration (t) for mechanically better washing the items to be washed.
  • the motion frequency (f) is kept lower for the parts such as spring, etc.
  • the control unit (5) enables the drum (3) to oscillate for a predetermined first duration (t1) if the load amount (W) in the drum (3) is higher than a predetermined limit load amount (Wlim) (W>Wlim).
  • the control unit (5) enables the drum (3) to oscillate by controlling the motion mechanism (4) for a first duration (t1).
  • control unit (5) enables the drum (3) to oscillate for a predetermined second duration (t2) that is shorter than the first duration (t1) (t2 ⁇ t1), if the load amount (W) in the drum (3) is lower than a predetermined limit load amount (Wlim) (W ⁇ Wlim).
  • t2 the first duration
  • Wlim a predetermined limit load amount
  • control unit (5) enables the drum (3) to oscillate in a predetermined first frequency (f1) if the load amount (W) in the drum (3) is higher than a predetermined limit load amount (Wlim) (W>Wlim).
  • f1 a predetermined limit load amount
  • the control unit (5) enables the drum (3) to oscillate by driving the motion mechanism (4) in a first frequency (f1).
  • control unit (5) enables the drum (3) to oscillate in a predetermined second frequency (f2) that is higher than the first frequency (f1) (f2>f1), if the load amount (W) in the drum (3) is lower than a predetermined limit load amount (Wlim) (W ⁇ Wlim).
  • f2 the first frequency
  • Wlim a predetermined limit load amount
  • control unit (5) determines the duration (t) of oscillation motion of the drum (3) in direct proportion to the load amount (W) in the drum (3). In this embodiment, the control unit (5) determines a separate motion duration (t) according to each separate load amount (W). Thus, as the load amount (W) increases, the duration in which the items to be washed are in contact with each other is extended and the mechanical washing effect is enhanced by oscillating the drum (3) for a longer duration (t).
  • control unit (5) determines the duration (t) of oscillation motion of the drum (3) between a predetermined third duration (t3) that is at most longer than the first duration (t1) (t3>t1), and a predetermined fourth duration (t4) that is at least shorter than the second duration (t2) (t4 ⁇ t2).
  • the maximum duration (t) of the oscillation motion is the third duration (t3) and the minimum duration is the fourth duration (t4), without depending on the load amount (W).
  • control unit (5) determines the frequency (f) of oscillation motion of the drum (3) in inverse proportion to the load amount (W) in the drum (3). In this embodiment, the control unit (5) determines a separate motion frequency (f) according to each separate load amount (W). Thus, as the load amount (W) increases, the motion mechanism (4) is prevented from overworking and its useful lifetime is increased by oscillating the drum (3) in a lower frequency.
  • control unit (5) determines the frequency (f) of the oscillation motion of the drum (3) between a predetermined third frequency (f3) that is at least lower than the first frequency (f1) (f3 ⁇ f1), and a predetermined fourth frequency (f4) that is at most higher than the second frequency (f2) (f4>f2).
  • the maximum frequency (f) of the oscillation motion is the third frequency (f3) and the minimum frequency is the fourth frequency (f4), without depending on the load amount (W).
  • the control unit (5) calculates the load amount (W) in the drum (3) using the amount of water in the drum (3). As the weight of the items to be washed added into the drum (3) increases, the items absorb more water and therefore more water is received into the drum (3) to reach the required water level in the drum (3). There is thus a direct proportion between the load amount (W) in the drum (3) and the amount of water received into the drum (3). The control unit (5) determines the load amount (W) in the drum (3) using the relationship between the load amount (W) and the water amount.
  • control unit (5) decreases the amplitude provided by the motion mechanism (4) upon the amount of water in the drum (3) exceeding a predetermined limit value.
  • the safety of the washer (1) is enhanced by completely preventing the water in the drum (3) from leaking out/overflowing.
  • the parameters of the oscillation motion of the drum (3) is determined according to the load amount (W).
  • the load amount (W) is high, the drum (3) is able to oscillate for a longer duration to enhance the mechanical washing effect.
  • the motion mechanism (4) is prevented from overworking and its useful lifetime is increased by oscillating the drum (3) in a low frequency (f).
