Definitions
- the present invention relates to a laundry washing machine of the top-charging type, particularly for domestic use, provided with a counterweight for the dynamic equilibration of the tub-drum assembly of the machine.
- laundry washing machines of the top-charging type are at present being constructed to have the smallest possible dimensions so as to permit them to be installed in limited spaces.
- the efficient dynamic equilibration of the tub-drum assembly of laundry washing machines of this type requires the employ of at least one counterweight formed of a material having a high specific weight.
- This material may be contained in a suitably formed container or may itself be formed to a compact block.
- the counterweight is generally attached to the outer periphery of the tub at a lower or lateral portion thereof. This manner of mounting the counterweight requires it to be considerably heavy and thus to have relatively great dimensions, so that the accommodation of the counterwieght in a washing machine of reduced dimensions offers considerable difficulties.
- a laundry washing machine of the top-charging type particularly for domestic use, comprising a tub suspended in a frame of the machine, a drum rotatably mounted in said tub and provided with two spring-biased peripheral doors adapted to partially overlap one another in the closed position, and at least one counterweight of a material having a high specific weight for the dynamic equilibration of the tub-drum assembly, said tub being provided with a top opening giving access to said drum.
- a laundry washing machine of the above specified type is characterized in that said counterweight is formed with at least one central through-opening and is mounted on the top portion of said tub, so that said through-opening coincides with said access opening and with a charging port formed in the frame of the machine, flexible means being provided for connection to the respective peripheral borders of said counterweight and said charging port.
- a laundry washing machine of the top-charging type comprising a washing tub 3 suspended within an outer frame 4 by means of a not shown system of upper springs and lower shock absorbers, and a drum 5 rotatably mounted within tub 3 and provided with a peripheral opening 6 adapted to be closed by spring-biased door flaps 7, only one of which is shown in fig. 1, adapted to overlap one another in the closed position.
- a through-opening 8 Formed in the upper portion of tub 3 is a through-opening 8 giving access to drum 5 for introducing and discharging the laundry into and out of drum 5, respectively.
- a counterweight 9 formed of a material having a high specific weight, such as cement, baryte or the like, which may be contained within a suitably shaped container or be formed as a compact block of the selected material.
- Counterweight 9 is formed with at least one central through-opening 10 and with a channel-shaped outer peripheral rim 11 for purposes to be described later.
- counterweight 9 For mounting counterweight 9 in the laundry washing machine, it is located on the top portion of tub 3 in such a position that its through-opening 10 coincides with a charging port 12 formed in the frame of the machine thereabove, and with.the access opening 8 of the tub. In this position the counterweight is subsequently affixed to the tub of the machine by means of bolts 13 and nuts 14 or equivalent fastener elements.
- Charging port 12 is surrounded by a frame structure 15 acting as a charging funnel and having a free edge 16 partially projecting into the interior of the machine.
- a bellows-shaped flexible element 17 Connected between the free edge portion 16 of frame structure 15 and channel-shaped outer peripheral rim 11 of counterweight 9 is a bellows-shaped flexible element 17 for permitting the laundry to be safely introduced into and withdrawn from drum 5.
- a profiled rigid clamping element 19 is slipped onto the contacting edge portions.
- the other free edge portion 20 of flexible element 17 is introduced into the channel-shaped edge 11 of counterweight 9 and retained therein by means of an expansible annular member 21.
- the flexible element 17 may have a different shape and be connected between the charging port and the counterweight in a different manner without thereby leaving the scope of the invention.
- counterweight 9 is formed with to opposing lateral edge portions 22 partially projecting into opening 10 for being engaged by a hooks 23 provided on the door flaps of the drum, should the latter be rotated with its door flaps accidentally open.
- the described location of the counterweight on top of the tub of the washing machine results in an upwards displacement of the center of gravity of the tub-drum assembly and thus in a shorter lever arm of the center of gravity with respect to the suspension points of the assembly within the frame of the machine.
- the dynamic equilibration of the said assembly is achieved by employign a counterweight of the same Material as abobe specified, although of reduced weight, so that the counterweight may be designed with reduced dimensions and formed of a reduced amount of material.
