Definitions

  • the present invention relates to a combined opening device for the door and the product box of a washing machine with front opening.
  • top-loading washing machines and front-loading washing machines also known as front-loading.
  • front-loading This latter type can be considered less ergonomic in certain aspects and in particular with regard to the operation of loading the product boxes and opening the door, the opening of the product box being carried out on the front face as for the drum access door.
  • a simple press of a button generally triggers the assisted opening of the door without handling on the one hand, and in addition, the product boxes are immediately accessible for filling on the other. go.
  • the opening of the door is not enough to make the boxes of products which are traditionally housed on the machine's dashboard directly accessible, in the form of a drawer.
  • washing machines with front loading where the opening of the product box is triggered by a push button but the box and door openings are not made by the same command, which requires two manual operations from the user. Furthermore, the closing of the door does not command the closing of the box, hence another additional operation.
  • the object of the invention is to provide a combined opening of the door and of the product box of a front-loading washing machine.
  • the subject of the invention is a device for the combined opening of the access door to the drum of a front-loading washing machine and of the product box, characterized in that it comprises an operating control on means for opening the door and on delay means, the delay means acting on means for opening the product container, the delay means creating at least one infinite delay.
  • the main advantages of the invention are that it improves the ergonomics of front-loading washing machines, that it allows the door to be opened only, that it allows the door and the product container to be closed or opened simultaneously by the same command, that it allows braking of the travel of the product box at the opening, in particular not to spill the products present, that it is simple to implement and that it is economical.
  • Figure 1 shows a front loading washing machine 1. It has a door 2 for access to the drum, located on the front face. This door generally has a symmetry of revolution, for example in the form of a porthole. For aesthetic reasons, it can also cover the entire front of the washing machine with the exception, however, of the dashboard 3.
  • the latter traditionally has a place for the passage of the product box 4 made in the form of a drawer with rectilinear movement or in the form of a quarter-round container with circular movement, the box opening forward in both cases.
  • Figure 2 shows the access door 2 and the product box, made for example as a rectilinear movement drawer, in the open state. Buttons not shown allow you to control the openings.
  • Figure 3 shows a block diagram of a device according to the invention.
  • the latter includes a control 31 which acts simultaneously on means 32 for opening the door 2 for accessing the drum of the washing machine and on delay means 33.
  • These delay means preferably carry out at least two delays.
  • a first time delay ⁇ t acts so as to delay the opening of the product box 4 relative to the door 2.
  • the time delay means 33 act on means 34 for opening the product box.
  • the time delay ⁇ t can be very short and / or approximate.
  • a second time delay is itself of infinite duration so as to allow the user to open only the door 2 without opening the product box 4 in the case in particular where the user wishes to have access only to the drum of the washing machine without worrying about the condition of the product box for example.
  • the delay time is defined by the state of the command 31.
  • the control 1 can, for example, be a push button or a rotary button whose first straight or circular stroke controls the infinite time delay, in the event that the product box is not opened.
  • the second race controls the first time delay At above.
  • the stroke of the button is for example read by the timing means 33. As soon as the first stroke of the button is engaged, the means 32 for opening the door 2 for accessing the drum begin, for example, to act.
  • FIG. 4 illustrates by a top view an example of a possible, non-limiting embodiment, of a device according to the invention.
  • a control 31 for opening the door and the product box is arranged on the device.
  • the drawer is shown in the closed position.
  • the two openings can be triggered almost simultaneously by action on the control 31.
  • the first time delay ⁇ t being very low, defined for example by the duration of the first stroke of the control 31.
  • Ease of use specific to top-loading washing machines as explained in the introduction is then available on a front-loading washing machine since in this case, the product box is automatically presented to the user.
  • the the user is also able to open only door 2, for example to unload the laundry. This possibility depends for example on the travel of the control 31.
  • the box is for example composed of two main parts, a drawer 41 receiving the products and a support 42.
  • the stroke of the drawer is for example braked.
  • the principle of braking the stroke of the gearbox is based on the admission or the controlled exhaust of air in a kind of jack consisting of a cylinder 43 and a piston 44.
  • a part of this jack is for example produced in the box support 42, this part constitutes the cylinder 43.
  • the other part of the jack, the piston 44 is removable and is fixed to the drawer.
  • the piston 44 is for example fixed on the front part of the product compartments, these compartments being fixed in the drawer. The details of these compartments are not shown.
  • the piston is for example fixed on the drawer by means of hooks or by means of screws 45, the piston making a quarter turn. These screws can, for example, both secure the piston and the compartments on the drawer.
  • the assembly consisting of the drawer 41 and the piston 44 slides in the cylinder 43, an integral part of the support 42, which is fixed relative to the body of the washing machine.
  • a plug 46 in which a calibrated hole 460 is formed closes the cylinder and guides the piston in translation.
  • a circular seal 461 is for example interposed between the plug 46 and the piston 44.
  • a flexible cup 47 for example closes the space between the piston 44 and the cylinder 43. This cup is for example made of rubber.
  • a spring 48 for example helical, exerts a restoring force between the cylinder 43 and the piston 44.
  • the spring is for example located between the part of the support 42 constituting the bottom of the cylinder 43 and a circular lug 49 integral piston 44.
  • a hook 50 comes into contact with a retaining system 51.
  • the drawer is then blocked.
  • the hook 50 is detached from the retaining means, which releases the force of the spring 48 which then pushes the drawer outwards.
  • Cup 47 enters at this time in contact with the cylinder 43 and thus ensures a seal preventing the air filling of the part 431 of the cylinder 43 between this cup 47 and the part of the support 42 constituting the bottom of the cylinder.
  • the filling of the cylinder is imposed by a hole 440 formed in the piston 44, this hole 440 is for example formed in a section 441 closing the inside of the piston, this section being located towards the front of the piston, towards the outside.
  • a hole 442 made in the compartments ensures the continuity of the air passage from the outside.
  • the flexible cup 47 could be replaced by a sliding adjustment of the parts 43, 44.
  • the hole 440 made in the piston 44 is calibrated so as to let air pass only at a speed calculated so that the assembly consisting of the drawer 41 and of the piston 44 so that only slowly relative to the support 42. By this braking, any sudden exit from the product box is thus avoided, which prevents on the one hand spilling the detergents and on the other hand surprising users .
  • the shape of the flexible cup 47 is designed to fold to let air escape at the same time as the spring is compressed. The air then escapes through the hole 460 formed in the plug 46 dimensioned accordingly.
  • the control 31 is for example made up of a push button returned to the rest position by a spring 52.
  • the push button comprises for example a cap 53 resting on a movable body 53 which is guided rectilinearly by a fixed body 54 fixed to the wall 55 of the washing machine.
  • the aforementioned timing means are for example integrated in the control 31 shown in longitudinal section in Figure 4.
  • the section of the movable body 53 being for example rectangular and flattened, a notch 56 is for example made in the thickness of the movable body.
  • this notch is first rectilinear over a first distance in the direction of travel of the movable body then, while remaining for example rectilinear, makes an angle with respect to this race over a second distance , the notch moving away from the hook 50 by which the drawer 41 is retained.
  • a lug 57 secured to an element 51 which retains the hook 50.
  • This retaining element 51 is guided by the fixed body 54 according to a movement for example perpendicular to the movable body 53 ' .
  • the lug 57 moves relatively in the part of the notch 56 parallel to the movement of the button.
  • the end of the movable body 53 ' closes an electrical contact 58, which triggers the opening of the door 2 for access to the washing machine drum.
  • the mechanism for opening a washing machine door from an electrical control is known to those skilled in the art and is therefore not shown or described.
  • the electrical control can be replaced by a mechanical control also known to those skilled in the art.
  • buttons 53, 53 ' continues its movement in a second stroke, corresponding to the relative displacement of the lug in the part of the notch 56 moving away from the hook 50, the retaining element 51 is then attracted to a position which moves it away from the hook 50, which frees the latter and therefore the opening of the drawer 41.
  • a half-stroke pulse on the button 53 therefore triggers the opening of the door alone, while a full-width pulse opens also the product box.
  • the closing of the product box 4 can be automatic using the closing movement of the door 2.
  • a mechanical connection not shown for example a cable, connects the drawer 41 of the box and the hinge or an element from the door hinge, or the door itself.
  • the movement of the hinge for example makes it possible to apply a movement to the cable, a movement which is applied to the drawer 41 of the box to pull it towards the support 42.
  • This movement can be amplified by known means of reduction.
  • the piston 44 is removable from the drawer in order to simplify the construction but also to allow the drawer to be removed from the support 42 for cleaning the compartments. To this end, the piston is fixed by the aforementioned screws 45, which can be removed, for example, only by a quarter turn.
  • the invention is economical, insofar as it requires few additional parts compared to a conventional solution.
