FR2797649A3 - Controller for flushing valve for toilet - Google Patents

Abstract

The controller has a housing, and a lever (30) pivotally connected to the housing with a first end connected to the valve, and a second end protruding into the housing. A housing-like frame part (21) is fixed in the housing. An armature (24) slides in a tube (23) mounted in the frame part. A spring (40) connects one end of the armature to the second end of the lever. An electromagnetic device (25,26) actuates the armature inside the tube to actuate the lever via the spring.

Description

The present invention relates to a

  control device for flushing, and more particularly a control device

  electromagnetic for flushing.

  Conventional flushes include a lever coupled to a flush valve through a link. The lever must be actuated by

  a force large enough to overcome the applied water pressure

quée on the flush valve.

  The object of the present invention is to reduce, and / or suppress

  sea, the previously described drawbacks of

classic toilet flush.

  The primary objective of the present invention is to provide an electromagnetic control device for flushing which can

  operate efficiently and economically.

  The present invention provides a control device

  to control a flush valve, the

  control comprising a housing, a lever pivotally coupled to the housing and including a first end coupled to the flush valve and including a second end extending towards the interior of the housing,

  a cover fixed in the housing, a tube arranged in the cover, an arma-

  slidingly housed in the tube and including a first end

  mite, a spring connecting the first end of the armature to the second

  end of the lever, and an electromagnetic means for actuating

  the armature towards the inside of the tube to actuate the lever via the res-

comes out.

  The electromagnetic means generates an electromagnetic field

  tick when the electromagnetic means is energized, the

  control also includes means for maintaining the electric field

  tromagnetic generated by the electromagnetic means. The electromagnetic field maintaining means includes a plurality of plates mounted on the tube and one or more magnets disposed on the plates to maintain the electromagnetic field generated by the electromagnetic means. The electromagnetic means includes a coil disposed on the tube for actuating the armature towards the inside of the tube and includes a

  another coil arranged on the tube to actuate the armature outwards

laughing tube.

  In addition, a seat is attached to the hood and has a recess

  ment, a second end of the frame to be housed in this recess of the seat. A fixing device is also provided for

  fix the housing to the flush tank.

  The present invention will be better understood on reading the

  following detailed description, with reference to the accompanying drawings

in which:

  Figure 1 is a perspective view of a device for

  mande according to the present invention; Figure 2 is a sectional view of a flush with the control device according to the present invention; Figure 3 is a perspective view of a W.C .;

  Figures 4 and 5 are partial exploded views of the device

  tif control according to the present invention;

  Figures 6, 7 and 8 are partial sectional views illus-

  tring the operation of the control device according to the present invention. Referring firstly to Figures 1 to 4, a control device according to the present invention comprises a housing 10 including a support 11 fixed on one side and including a tube 12 extending from the other

  side. A threaded rod 13 includes a support 14 fixed to one of its ex-

  hoppers, its other end being screwed into the tube 12. Two nuts, 16 are screwed onto the threaded rod 13 to cooperate with the tube 12

  and to press the housing 10 of the control device against the

  toilet flush. The tank includes a flush valve and

  a link connecting the valve to a lever 30 of the control device

  of 10. The control device includes a sensor, such as an infrared ray sensor 51 disposed in a box 50 placed above the tank for detecting the user and for controlling the control device. The housing 10 includes a chamber 17 formed to receive a cover 21 of the electromagnetic device 20, and includes a channel 18

  formed to receive a middle part of the lever 30. The lever 30 in-

  one end coupled to the link and another end extending

  towards the inside of the housing 10.

  Referring now to Figures 4, 5 and 6, the electromagnetic device 20 includes a seat 22 attached to one end of the cover 21 and has a recess 221. The cover 21 includes a cover 29 attached to the other end and having one or more protrusions 291 intended to be fitted into the cover 21. The cover 29 is preferably firmly fixed to the cover 21, for example by welding. A tube 23 is disposed in the cover 21 and has a fixed end

  to the cover 29, and another end aligned with the seat 22 or

  pledged in it. A movable armature 24 is slidably engaged

  ment in the tube 23 and has an end 241 intended to be

  engaged in the recess 221 of the seat 22, its other end being covered

  folded at the other end of the lever 30 by a spring 40. Two coils

  , 26 are engaged in the tube 23 to generate electro-

  magnetic in different directions and to move the armature 24

  in different directions along the tube 23. A number of plates

  ques of silicon steel 27 are engaged on one end of the tube 23 and one or more permanent magnets 28 are arranged above and

below the plates 27.

  The cover 21, the frame 24, the seat 22, the plates 27 and the

  cover 29 are made of materials permeable to magnetic fields

  to form the magnetic induction (Figure 8) for the electromagnetic device 20. The tube 23 is made of a material which does not have

no magnetic permeability.

  In operation, when the coil 25 is energized, the armature

  24 can be moved towards the inside of the tube 23 by the magnetic field

  as generated by the coil 25 (Figures 7 and 8). Plates 27 is the ai-

  permanent mants 28 can maintain the magnetic field so that the coil 25 need only be energized for about 0.5 seconds. The energy required to activate the coil 25 is thus significantly reduced. The lever 30 can thus rotate around the middle section by the armature 24 via the spring 40. It will be noted that

  the armature 24 is not directly coupled to the lever 30, but is

  indirectly bent to the lever 30 via the spring 40, so that the force applied to the frame 24 is not required. When the coil 26

  is energized for about 0.5 seconds, armature 24 can be pushed

  sée outwardly of the cover 21 (Figure 6) to release the lever 30, and the plates 27 and the permanent magnets 28 can maintain the magnetic field so that the coil 26 can also be excited with the lowest possible energy. Or, without a coil 26, the armature 24 can also be moved towards the outside of the cover 21

  by a constraint element when the coil 25 is de-energized.

  Consequently, the flush according to the present invention

  includes an electromagnetic control device which can operate

  to operate efficiently and economically.

  It is understood that the foregoing description has not been given

  born only for illustration and not limitation and that variants

  or modifications may be made to it as part of the pre-

  invention, as described in the claims which follow.
