Definitions

  • the present invention relates to a laundry drying and/or washing appliance equipped with an autonomous fire extinguishing or fire starting system.
  • the patent application FR-A1-2 614 209 describes a fire-fighting device for electrical appliances containing flammable components and in particular for a washing machine or dryer.
  • a laundry drying and/or washing appliance is a household appliance which comprises a rotating drum in which laundry is placed for washing with water and a cleaning agent, or damp laundry for drying by stirring. .
  • the drum is generally rotated by a belt which is itself driven by an electric motor.
  • a washing machine can have a dryer function. In both cases, the drum of the device can be passed through by a flow of hot air so as to facilitate the drying of the laundry when it is tossed.
  • the heating and hot air flow generation system of the device may include a gas burner or an electric resistance for example.
  • This household appliance is the cause of many domestic fires. Heating and stirring the laundry in the drum generates flammable dust which accumulates inside the appliance and which is likely to ignite, particularly when deposited on very hot parts of the appliance. device such as the engine or the heating system. A fire caused by the ignition of dust can cause a larger fire in the device, particularly by ignition of the drum drive belt.
  • the patent application mentioned above proposes installing a tank in the form of a pressure bomb in a washing machine, this tank being connected to pipes that are normally closed and likely to rupture at a determined temperature threshold. These pipes extend to parts of the device which are subject to overheating or catching fire, such as electrical devices, resistances, the motor, flammable components, etc.
  • the fire-fighting substance contained in the tank is at least slightly under pressure and the distribution pipes are made of a material intended to melt to ensure the rupture or opening of these pipes when the latter are licked by flames or when the temperature of their environment exceeds a predetermined threshold. In this way, as soon as overheating or flammability conditions arise which could give rise to a fire inside the device, the pipes break and automatically distribute the fire-fighting substance to immediately extinguish the possible development of a fire.
  • the solution described in this patent application is, however, not entirely satisfactory because the fire extinguishing system formed by the tank and the pipes is complex and takes a long time to install in a household appliance. In fact, it includes several elements which must be installed and fixed one after the other and connected to each other in the device. These elements are located in several areas inside the device so that the installation of the system in the device can only be done during the manufacture of this device. Likewise, in the event of maintenance, it is necessary to dismantle several front panels of the device to access the system. The system described in this application cannot therefore easily be integrated into an existing device which would not have been originally designed to be equipped with this system.
  • the state of the art also includes the document US-B2-9,885,142 .
  • the present invention proposes a solution to at least part of the problems mentioned in the above, which is simple, effective and economical and allows both simple and rapid integration into the specific environment of a laundry drying and/or washing appliance.
  • the pipe also has its two ends which are closed in a watertight manner.
  • the pipe has an elongated shape and is made of a material facilitating on the one hand its shaping by heating (called thermoforming), before its assembly in the device, as well as allowing the release of the extinguishing fluid by melting and bursting.
  • the pipe is arranged in two portions.
  • a first portion of the pipe forms a cradle extending between the drum and the motor.
  • a cradle generally has a rounded or hollow shape, which allows it to extend around the drum and conform to its shape.
  • the pipe forms a loop which allows it to extend over the entire area between the motor and the drum, which is a critical area for the occurrence of fire, without risk of disrupting the operation of the device.
  • the second portion of the pipe extends on the side of the removable facade panel and for example along part of the drum drive belt.
  • FIG. 1 schematically represents a device 10 for drying and/or washing laundry, such as a tumble dryer, that is to say a household appliance designed to dry laundry by stirring it and subjecting it to a flow of hot air.
  • the device 10 can be intended for particular or professional use
  • the envelope 12 includes several facade panels 12a, 12b, some of which are removable.
  • a device 10 of this type may include a top or front loading hatch 19.
  • the device includes front panels, 4 in number (front, rear and side), at least some of which are removable for access, after disassembly and removal of at least least one of these panels, inside the envelope and the device.
  • the device includes a front loading hatch, in the form of a porthole for example, the device includes front panels of which at least one side panel is removable for the same reason.
  • the drum 14 defines any washing and/or drying volume which is adapted to its use (individual or professional).
  • the device 10 comprises other elements such as in particular an electronic member 22 for monitoring and controlling the various electrical equipment of the device, a condenser or a pipe 23 for evacuating hot air loaded with humidity, etc. .
  • the motor 16 includes an output shaft (not visible) which rotates the drum 14 around its axis 15 via a belt 24.
  • the belt 24 extends around the drum 14 and the shaft. output of the motor 16, or of a pulley driven by this shaft, and extends generally in a substantially horizontal plane P1.
  • the plane P1 is parallel to the side facade panels 12a of the device 10.
  • the axis of rotation of the drum 14 is also horizontal and perpendicular to these panels 12a.
  • the plane P1 would extend parallel to the rear panel of the device and the axis of rotation of the drum would be perpendicular to this rear panel. .
  • the heating system 18 can be of any type and is for example of the heating resistance type, gas burner type, etc.
  • the system 18 can be located under the drum 14 or on one side of the drum 14.
  • the fire extinguishing device 20 is specifically designed to be integrated into the appliance 10 and comprises a pipe 26 of elongated shape and closed at its two longitudinal ends.
  • the ends of the pipe 26 can be closed by plugs attached and fixed to the pipe, for example by gluing or welding. Alternatively, the ends of the pipe 26 could be directly closed by deformation and welding of its material.
  • the pipe 26 comprises a fusible thermoplastic wall delimiting an internal space 28 in which a fire extinguishing fluid 29 is stored, possibly under pressure (cf. figure 4 ).
  • This wall has, for example, a general circular shape in section.
  • the wall of the pipe in whole or in part, could have another shape in section, for example square, rectangular, oval, etc.
  • At least one of the ends of the pipe 26 could be equipped with a valve for filling the pipe with extinguishing fluid 29, as described in the application FR-A1-3 088 215 .
  • the extinguishing fluid 29 is configured to be released by melting of the wall of the pipe under the effect of the heat provided by a fire or start of fire,
  • the pipe 26 is thermoformed to impose a particular shape on it in the free state without constraint corresponding to its mounting position inside the envelope 12.
  • the material of the pipe will be described in more detail in the following with reference to there Figure 4 .
  • the device 20 essentially comprises two parts better visible to the figure 2 And 3 , namely a first part in the form of a cradle 30 which extends between the drum 14 and the motor 16, and a second part 32 which extends on the side of one of the removable panels, here the front panel 12b.
  • the first part is formed by a first portion of the pipe 26 which forms a loop delimiting the periphery of the cradle 30, and the second part is formed by a second portion of the pipe.
  • the device 20 is configured to be mounted in the envelope 12 by dismantling and removing one of the removable facade panels, namely the front panel 12b in the example shown.
  • the second portion 32 of the pipe 26 is located on the side of the panel 12b to facilitate the installation and fixing of the device 20 in the device.
  • the cradle 30 extends from this panel 12b to the opposite front panel, here the rear panel.
  • P3 comprises a rectilinear horizontal segment 36b which is located above the segments 26a of the intermediate plane, and which is parallel to a rectilinear horizontal segment 26c of the second plane P4.
  • the second portion 32 of the pipe has a general L shape. It comprises a rectilinear horizontal segment 32a running along the segment 26c of the second plane P3. This second portion 32 further comprises a vertical rectilinear segment 32b.
  • the segments 26a, 32b extend respectively in vertical planes P5, P6 and P7 parallel to each other and to the aforementioned plane P1.
  • P1 is here located between P6 and P7.
  • the cradle 30 has a width measured in the plane P2, between the segments 26a, which is less than the width of the second portion 32.
  • the width of this portion 32 corresponds substantially to the length of the segment 32a of this portion.
  • the pipe 26 can be fixed in two places on an element of the device 10, for example in zone Z1 on the inside of a facade panel of the envelope 12, and in zone Z2 on a casing made of material plastic located inside the envelope (for example that surrounding the motor 16 or a fan). Fixation can be done via plastic organs.
  • One of these ends 26x of the pipe 26 is preferably equipped with a pressure sensor 34 which is configured to measure the pressure of the fluid 29 and which is connected to the control member 22 of the device 10.
  • the member 22 is configured to put the device 10 in out-of-service mode when the pressure sensor 34 emits a signal corresponding to a pressure of the fluid 29 lower than a predetermined threshold.
  • the member 22 can also be configured to emit a signal to a portable electronic device such as a smartphone-type mobile telephone, in order to warn the user or owner of the device in the event of a malfunction of the device. this last.
  • the pipe 14 could be equipped with a sensor for measuring parameters other than pressure, such as temperature for example.
  • the wall of the pipe 26 can be of the single-layer or multi-layer type. It can for example comprise two layers, respectively internal and external.
  • the internal layer can be made of a material with low permeability compared to the extinguishing fluid 29, that is to say with a lower permeability or equal to 1 cm 3 .25 ⁇ m/m 2 .atm.24h. It is for example made of fluorinated thermoplastic or EVOH material.
  • the outer layer is made of a polyamide thermoplastic material, which generally has a permeability greater than that of the inner layer, and for example greater than or equal to 1 cm 3 .25 ⁇ m/m 2 .atm.24h.
  • the low permeability layer is located inside the higher permeability layer. Indeed, otherwise, there would be a risk of gas migrating through the internal layer with higher permeability and of stagnation of this gas at the interface between the two layers, likely to lead to delamination of the layers.
  • a single-layer pipe should have a significant thickness of layer with low permeability. In the context of a two-layer or multi-layer pipe, this resistance is ensured by the layer(s) with higher permeability, and the layer with low permeability can have a relatively small thickness sufficient to ensure the desired impermeability function.
  • the layer could be placed between two layers. This configuration would improve the mechanical strength of the layer during the pipe shaping stage (and thus avoid any risk of tearing of this layer), while guaranteeing optimal sealing of the pipe.
  • At least one has a fuse property under the effect of the heat generated by a fire or the start of a fire, and in particular under the effect of a temperature greater than or equal to 70°C, or even 120°C.
  • the two layers have such a fuse property.
  • the pipe 26 has an external diameter of between 10 and 30 mm, and preferably between 10 and 20mm.
  • the wall has a thickness of between 1 and 3mm, and preferably between 1 and 2mm.
  • the pipe 26 has for example a length of between 1 and 5m
  • the extinguishing fluid can be stored in the aforementioned space or cavity at a pressure greater than 1 bar and which can reach 10 bars, 20 bars, or even 30 bars.
  • the extinguishing fluid preferably does not include HFC gas of the R236Fa type because this gas has a very high GWP or GWP of around 9400.
  • the extinguishing fluid preferably has a GWP or GWP less than or equal to 5000.
  • the fluid may comprise at least one HFC gas and/or C 6 F 12 O, and/or CO 2 .
  • HFC gases that can be used, R227ea and R125 gases are preferred because they have a GWP or GWP of around 3400-3500.
  • the DuPont ® company for example, markets gases of this type under the names FE-25 and FM-200.
  • CO 2 is advantageous because it has a GWP or GWP of 1.
  • C 6 F 12 O is also advantageous because it has a GWP or GWP of 1.
  • the company 3M in particular markets this type of gas under the name Novec ® 1230 (FK-5-1-12).
  • THE figures 5 to 25 illustrate different variants illustrating several configurations for the device 10 and several possible installations and conformations for the device 20 and the pipe 16.
  • the axis 15 of rotation of the drum 14 extends in the plane of the drawings. This axis is horizontal to figures 5 to 10 , 17 to 21 , and vertical to the Figure 25 . In the figures 11 to 16 , And 22 to 24 , this axis 15 is perpendicular to the plane of the drawings.
  • the motor 16 and the heating system 18 can have different dimensions and positions in the envelope of the device 10. This is also the case for the belt 24.
  • each of the parts of the pipe 14 can be adapted according to the dimensions and positions of the motor 16, and/or the system 18 and/or the belt 24.
