Abstract
Description
- The present invention concerns an integral flow directing filter unit for washing machines and the like.
- The current need to reduce the consumption of water for washing and concurrently the consumption of detergent and energy for heating is recognised.
- To achieve this it is known that the wash bath is recirculated around a recirculation path.
- Two approaches are employed in pursuit of this aim.
- According to one approach a single pump is used in combination with a diverting valve to convey the wash liquid to a drainage outlet or alternatively to a recirculation path.
- Original arrangements embodying this approach are described in Italian patent application no. MI92A002596 filed on 12 November 1992, and in Italian patent application no. M192A002562 filed on 9 November 1992.
- In accordance with the second approach two separate pumps are utilised to convey the washing liquid respectively to a drainage outlet or into the recirculation path.
- The first approach necessitates the use of a diverting valve which must satisfy the requirement of providing a perfect seal at the diversion point, failing which, after repeated operation liquid lost through the drain results in the gradual emptying of the washing vessel during recirculation, with the risk of failure of the washing machine due to insufficient residual liquid in the washing vessel.
- This requirement is difficult to satisfy even if a filter, upstream of the diverting valve, can give relative protection by preventing threads and particles of a certain dimension from interfering at the diversion point and preventing a liquid-tight seal from being made.
- The formation of encrustations and solid deposits of particles having dimensions smaller than those caught by the filter cannot be prevented and this can lead to the escape of liquid, and mechanical blockage of the diverting valve.
- The effectiveness of the valve can therefore be assured only by proper maintenance.
- These disadvantages are not present in the second approach but, on the other hand, it is considerably more expensive due essentially to the more complex operations needed to assemble two separate pumping units.
- In addition the dual hydraulic circuit does not allow the use of an appropriate single filter acting both in the drainage and the recirculation circuit.
- The dual hydraulic circuit also removes a certain quantity of water from the washing circuit which can be considered lost for washing purpose.
- To avoid such disadvantages the integral flow-directing unit with two independent pumps and a common filter which is the subject of the present invention provides a filter and a pair of structurally independent pumping means combined in a single monobloc structure.
- The unit requires a single mechanical support rather than separate supports for separate functional units.
- According to a further aspect of the invention the unit has a single attachment on the body for connecting the wash vessel directly to the unit so as to reduce pipework to a minimum, and consequently to reduce also the volume of liquid which is not directly involved in the washing process.
- There is therefore an indirect reduction in energy consumption.
- The design of the unit is such that it can be made by moulding plastics materials using relatively simple methods with a reduced number of dies and related operations.
- This result is attained by aligning the three flow ports on a first axis and aligning the body which houses the two pumps on a second axis perpendicular to the first. The filter housing is aligned on a third axis perpendicular to the second.
- In practice, a first part of the unit is made as a housing body for the pumps which are separated by a common delivery chamber communicating with a second part of the unit in which a housing for a filtration element is formed.
- This can be made in various ways, such as a barrier filter, in alignment with a self cleaning circuit with a filter opening, or as a conventional mesh filter.
- Brackets are formed integrally with the body to join the unit to the moving part of the washing machine.
- The characteristics and advantages of the invention will become clear from the following description of a preferred embodiment and from the accompanying drawings in which:
- Figure 1 is an exploded perspective view of a preferred embodiment of the integral flow directing unit with two independent pumps and a common filter in accordance with the present invention;
- Figure 2 is an end view of the body of the unit of Figure 1;
- Figure 3 is a side view of the body of the unit of Figure 1;
- Figure 4 is a sectional side view along a median plane of the body of Figure 2;
- Figure 5 is a sectional view on the line ABC of Figure 3;
- Figure 6 is a sectional plan view of the unit of Figure 1; and
- Figure 7 is a sectional side view on a median plane of the unit of Figure 1.
- With reference to Figure 1 the integral flow directing unit according to the present invention comprises a moulded body 1 in plastics material, a
removable filter 2 with a front closure plug 3 and twomotor units pump impeller 6, provided withflanges - Two portions can be essentially distinguished in the unitary body 1.
- A first portion forms two axially aligned cylindrical housings, open at their outer ends, with annular flanges respectively 9, 10 for coupling to
respective flanges - Each of the two housings comprises the body of a centrifugal pump with an
impeller 6, driven respectively by the twomotor units cylindrical filter housing 14 to the peripheral wall of which is connected anintake opening 15. - The body 1 is provided on the outer sides of the
filter housing 14 with twomounting brackets bosses - Figures 2 to 5 represent various views and sections of the body 1 to show more clearly the structural characteristics and its formation using a relatively simply constructed mould with a reduced number of moving parts.
- The filter housing is constructed from two axially aligned
cylindrical bodies 20, 21 (Figure 5) the outermost one 20, of greater diameter, being connected to the other by means of ashoulder 22 which has anannular ridge 23 for cooperation with a seal 24 (Figure 1) on the filter plug to ensure sealing of the filter housing. - The
body 20 comprises a plug housing and has on its edge two opposing retainingteeth teeth - The
inner body 21 constitutes the filter housing and theintake opening 15 is joined to and opens into its periphery. - Internally the
body 21 is joined to and communicates with asuction chamber 27 positioned between the twoimpeller housings apertures - The filter and plug housing, the suction chamber and the front part of the
mounting brackets arrow 32 which is provided with a pair of retractable teeth to form the necessary undercuts for theteeth impeller housings flanges arrows - The
impeller housings axial apertures - The
delivery outlets - When one of the
motor units inlet 15, enters into the filter chamber through the filter, passes into thesuction chamber 27 and from there to the impeller housing corresponding to the activated motor from where it is expelled through theassociated outlet - The
outlets inlet 15 are advantageously positioned along parallel axes, with a degree of inclination relative to the axis of the filter chamber. - Their interior and part of their exterior can be formed with a die closed in the direction of the
arrow 35, being clearly along the axes of the openings. - A fifth die closed in the direction of the
arrow 36 allows the formation of the lower part of the body 1, which is undercut with respect to the pump bodies and associatedflanges - Preferably, but not necessarily, to facilitate the separation of the body from the various dies, the upper exterior part of the
inlet 15 is formed by a die closed in the direction indicated by thearrow 37. - To form the integral flow directing filter unit according to the invention, the unitary body 1 is completed by attaching the two flanged
motor units - These are conveniently but not necessarily of the synchronous type, and made from a permanent magnet submersed rotor to the shaft of which is fitted an impeller 40, 41.
- The rotor housing is externally enclosed by the extensions of field poles 42, 43 which extend in two stator columns closed with a yoke.
- On the stator columns are two electrical excitation coils supplied by the alternating mains voltage.
- It is clear that the invention is susceptible to many variants.
- For example, a conventional mesh or labyrinth filter may be substituted for the diaphragm filter shown in Figure 2.
- In addition, in the case of the filter being superfluous, or where its separate production is preferred, the structure of the flow directing unit can be simplified by eliminating the filter housing completely and attaching the intermediate suction chamber directly to the
inlet 15, in this case positioned at an angle or in relative opposition to theoutlets - In other words the filter housing is replaced by the
inlet 15, the diameter of which must be sufficient to form at its end, and as an extension of itself, an intake chamber with dimensions suitable to keep the pressure drop between predetermined limits for a predetermined flow rate of liquid.
