  • the presence of this second sealing element 662 thus makes it possible to ensure sealing between the pump body 60 and the cover 64, while allowing disassembly and reassembly of the cover 64.
  • this second element of sealing 662 does not go all the way around the pump body 60.
  • the second sealing element is not located on the entire periphery of the chamber 68 but on at least 60% and preferably 80% of the periphery of the chamber 68.
  • the portion of the remaining periphery is then closed by a third sealing element 663, as will be more precisely described below, which makes it possible to ensure a total tightness between the pump body 60 and the cover 64, and therefore a tightness of the chamber 68.
  • the peristaltic pump also comprises a third sealing element 663.
  • the latter comprises a plate through which the inlet 61 and outlet 62 connectors pass.
  • the plate is made of silicone, or any other material capable of ensuring the seal.
  • the plate then comprises two orifices allowing the passage of the input 61 and output 62 connectors.
  • the plate is made of a sufficiently elastic material to ensure sealing around said input 61 and output 62 connectors. then in contact with the input 61 and output 62 connectors, the pump body 60, but also the cover 64 as can be seen in the figure 7 .
  • This plate makes it possible in a remarkable way, in association with the second sealing element 662 previously described, to complete the sealing of the chamber 68, that is to say to complete the sealing between the cover 64 and the pump body 60, coming to close the periphery of the chamber.
  • the chamber 68 is completely sealed. Consequently, if liquid were to accidentally (breakage or disconnection of the deformable pipe 63) escape from the deformable pipe 63 and end up in the chamber 68, the liquid, generally water, would be trapped in the chamber. 68 without being able to escape.
  • This makes it possible to obtain a peristaltic pump that is particularly safe because it is completely sealed, that is to say unable to let any liquid escape, even in the event of its deformable pipe breaking. It is then possible to use the peristaltic pump of the invention in locations where any presence of liquid is prohibited, such as for example in the immediate vicinity of electrical or electronic components.
  • the invention as illustrated includes another safety device, which may moreover constitute an invention as such.
  • the pump shown on figures 6 and 7 comprises a drain device 67 designed to, in the event of rupture of the deformable pipe 63 of the peristaltic pump 6, drain the liquid from the chamber 68 towards the outside of the peristaltic pump 6 according to a controlled trajectory.
  • This safety device is particularly effective when it is associated with a household appliance 1 which includes a liquid evacuation device 114, as detailed below.
  • the peristaltic pump 6 comprises two holes 671 which then form a drain device 67 connecting the chamber 68 and the outside of the pump at a precise location, judiciously selected by the designers.
  • Each of the holes has a diameter of approximately 1.2 mm, which corresponds to an evacuation section of 2.26 mm 2 .
  • the holes are spaced 2.5 mm apart.
  • the emptying device 67 By combining the emptying device 67 with the sealing elements 661, 662, 663 previously defined, as shown, the controlled emptying of the chamber 68, after a rupture of the deformable pipe 63, only by the emptying device 67, is guaranteed regardless of the orientation of the pump in space. Indeed, if the pump is oriented in accordance with the figure 6 , then the liquid will naturally, by gravity, flow through the emptying device 67 which is then at a low point of the pump body.
  • first sealing element 661 and of the third sealing element 663 are, in this case, not necessary for good flow only by the emptying device since these elements are then located above the emptying device 67
  • the emptying device 67 finds itself at a high point of the pump.
  • the liquid could then flow through the gap between the pump body 60 and the inlet 61 and outlet 62 connectors.
  • the liquid could also escape through the gap between the drive shaft 51 and the pump body 60, even before reaching the emptying device 67.
  • the drain device 67 of the peristaltic pump 6 communicates with the evacuation device 114 of the box 111.
  • the emptying device 67 is located opposite the evacuation device 114.
  • the emptying device 67 is located opposite the evacuation device 114. More precisely, the emptying device 67 comprises two holes 671, the evacuation device 114 also comprises two orifices 1141, each of the holes 671 belonging to the emptying device 67 being arranged opposite, that is to say opposite, a orifice 1141 of the evacuation device 114.
  • the evacuation section of the emptying device 67 and that of the evacuation device 114 are substantially identical and of the order of 2.26 mm 2 which guarantees the total flow of the liquid which could be in the chamber 68 without funnel phenomenon.
  • the emptying 67 and evacuation 114 devices are then separated by a sealing element 664 ensuring the seal, in this case an O-ring, between the emptying device and the evacuation device 114.
  • the element of sealing 664 is held in a housing around the drain device 67 and is then in contact with the box 111 and the peristaltic pump 6, and in particular of the pump body 60.
  • the liquid in the event of rupture of the deformable pipe 63 of the peristaltic pump 6 of the household appliance 1, the liquid would then be evacuated in a controlled manner, defined by design , that is to say in a reflective manner, only by the evacuation device 114, and via the drain device 67 of the peristaltic pump 6, so that the liquid cannot come into contact with any electrical component or electronics located inside the box 111.
  • the inside of the box 111 is protected from any possible liquid, even in the event of a failure within the peristaltic pump 6, which considerably improves safety. of the household appliance 1, whether for the appliance itself (its electrical or electronic components) and for the user (risk of electrocution).
