  Multi-function household appliance having a device

  safety device to prevent unintentional access to

cutting and similar tools.

  The subject of the invention is an electroména-

  containing a container with a lid, a conduit for

  hopper having an open end opening into the container

  and a mouth accessible from the outside of the container, a tool mounted in said container near the end

  hopper duct and an electric motor for controlling

  This tool is equipped with a safety device to prevent unintentional access.

  to the cutting blades constituting the tool.

  The invention relates more particularly to a

  household appliance used to treat, in particular for

  per, slice, chop, chop, centrifuge, fruits, vegetables and similar food products, this device

  being equipped with a safety device to prevent unauthorized access

  accidental, accidental or unconscious to the area of the apparatus in which a tool acts to perform one or more of the above-mentioned functions A multi-function household appliance of the type in question comprises a container, a hopper duct having an open end opening into the container and a mouth accessible from the outside of the container, a tool mounted in said container near

  the open end of the hopper duct and a motor for controlling

  der the working movement of the tool.

  It is known that in the case of household appliances of the type mentioned above, one of the standards of

  priority should be to prevent

  expensive that the user can come into contact with the tool (for

  cutting blades) of the appliance during its operation.

  while allowing the charging of this device with the

  or food products to be processed (mince, chop, etc.).

  Until now, the devices or

  structures adopted to respect the above condition

2 2539291,

  are obviously complicated, storytelling, bulky

  and, in many cases, they are lab manipulators

  These drawbacks may lead the user of the appliance to "forget" the implementation or use of the safety device. The user then operates on the appliance.

  in a situation of risk that is not always clear.

prominently.

  The main purpose of the invention is to create an app-

  appliance of the type mentioned above, this appliance

  being equipped with a safety device capable of avoiding incon-

  mentioned above with reference to the known art.

  To this end, the invention relates to a household appliance of the type above characterized in that it comprises an interception member guided on the appliance to move from a first position, in which it is in front

  from the mouth of the hopper duct to at least a second

  tion, in which it is distant from that mouth, and a

  microswitch electrically connected in the supply circuit

  of the electric motor, this microswitch being

  born in a closed position by a part of the inter-

  ception stopped in the first position.

  Advantageously and according to a form of

  In a preferred embodiment, the interception member comprises a substantially rod-shaped element, one end of which is rotatably mounted on a pivot carried by the lid of the receptacle, this pivot extending parallel and laterally to the hopper duct.

  at least one section of the bar-shaped element being substantially

  coplanarly with the mouth of the hopper duct and

  being provided with the actuating part of the microswitch.

  The main advantage obtained with an appliance according to the invention is that the interception member intervenes not only to effectively prevent

  access to the appliance tool during its operation

  not only to allow the operation of this

  apparatus only when that organ is positioned behind the

  closure of the hopper duct (safety position) Another N

  significant benefit results from the simplified construction and operation of the appliance safety device

according to the invention.

  The invention will now be described in more detail with reference to the accompanying drawings, in which Fig. 1 is an elevational view in partial section of an appliance provided with the safety device according to the invention; Fig 2 shows in perspective the apparatus according to Fig 1; In the figures above, we have designated by 1

  as a whole a household appliance according to the invention.

  This is preferably a multi-function type apparatus which is able to perform, when equipped with appropriate tools, a variety of operations, for example slicing, chopping, to mince, centrifuge, mix,

  beating, etc., fruits, vegetables and food products

  Such an apparatus comprises a body 2 in which is formed a housing 3 intended to receive an electric motor

  a container 6 is positioned and removably fixed with conventional means and not shown The container 6 is closed at its upper part by a lid 7 Inside the container 6 extends a motor shaft 8 carried by the base 5 within which an end portion of the shaft is connected to a transmission (not shown because it is known

  in itself) actuated by the electric motor 4.

  A hopper conduit for changing the container 6 with fruits, vegetables, or other similar foodstuffs to be treated has been designated by 9. In a preferred but non-limiting embodiment, the hopper conduit 9 is formed as a single unit. piece with the lid 7, with respect to which it extends mainly outwards

  of the container 6, when the lid is disposed on the container.

  Numeral 10 denotes the end of the hopper duct which is open towards the container 6 The mouth of the hopper duct is designated by 11, -4

  Only by way of example, the drive shaft 8 is made integral in rotation, by conventional means not shown, a cutting blade 12 extending radially by

  relative to the shaft and rotating in the applied position on the end

  10 of the hopper conduit 9 of the container 6. The appliance previously described

  is equipped with a safety device to prevent a user from

  any person may accidentally access, through

  from the hopper duct 9, to the cutting blade 12 during the

operation of the device.

  In general, this safety device comprises an interception member 13 and a microswitch 14 connected in a manner known and conventional in the circuit

  electric power supply (not shown) of the electric motor 4.

  More specifically, and referring to the "ready-to-use" condition of the household appliance according to the invention, the interception member 13 comprises an element 13 'essentially shaped in the form of a stirrup (in V) and constituted by two parallel unequal arms in the form of bars 15, 16 and by a bar-shaped intermediate section 17 i The arms 15, 16 of the stirrup-shaped element 13 'extend parallel to the opposite sides of the conduit 4 hopper 9, while the bar-shaped section 17 is substantially coplanar with the mouth 11 of the hopper duct 9 The lower end of the arm 15 is rotatably mounted on a pivot 18 carried by the cover 7 and

  extending parallel and laterally to the hopper duct 9.

  The arm 16 has a lower part 16 has

  gaging in a light 19 practiced in the housing 3 of the body

  2 and extending concentrically with the pivot axis 18.

  lower free end of the arm 16, located inside the housing 3, intercepts and actuates the microswitch 14 when the intermediate rod-shaped portion 17 of the element 13 '

  in the form of a stirrup extends transversely with respect to the mouthpiece

  11 of the hopper duct 9 in a position substantially

central on it.

2539291 -

  It is clear that in this position the intermediate rod-shaped section 17 of the stirrup-shaped element 13 '(interception member) prevents the user or any other person from entering the hand into the hopper duct. 9 and access the cutting blade 12 during the operation of the appliance In addition, it is clear that as soon as the bar-shaped section 17 is moved from the interception seat above, the lower free end of the arm 16 of the stirrup-shaped element 13 'is moved away from the microswitch 14 As a result, the motor 4 can no longer operate. The interception element-13 therefore does not allow

  the operation of the household appliance according to the invention

  except when it is put in the safety position.

  It should be noted that in the case of a preferred and non-limiting embodiment, the cover

  7 is of the type provided with means that do not give permission to function.

  When the cover is properly positioned for closing the container 6, for example, this cover 7 is provided with a toothing (not shown) which attacks, through

  the light 19 mentioned above, a microswitch cor-

  respondent (not shown) mounted in housing 3 of the body 2

of the household appliance.

  Of course, the dimensions of the bow-shaped member 13 ', in particular the length of the arms 15, 16 thereof, vary according to the height of the hopper duct 9 above the cover 7. the length and the width of the intermediate section 17 of this stirrup-shaped element 13 'vary according to the transverse dimensions of the mouthpiece

it leads to hopper 9.
