Definitions
- the present invention relates to an apparatus with a motor and a liquid tank provided with a heating resistance.
- the problem of sealing the tank of the appliance is usually raised, and noise generated by the heating element (s) which vibrate during its operation.
- the resistance ensuring the heating of the liquid is often fixed on the side wall and near the bottom of the tank, so as to have its heating body being inside the tank, and its ends protruding through this wall, towards the outside of the tank to allow the power supply connections. This crossing of the wall of the tank by the heating resistor raises the problem of sealing of this tank.
- Many known solutions have been made to this problem in order to correctly carry out both the fixing of this heating resistor and the sealing of the tank.
- the device motor creates, during its operation, vibrations which are transmitted to the tank and the heating resistance and cause repeated shocks between this heating resistance and the bottom of the tank. .
- These mechanical shocks generate an unpleasant noise.
- a known solution consists in drilling one or more holes in the bottom of the tank of the device to mount one or more devices intended to hold the body of the heating resistor. This solution proves effective in suppressing the noise generated by the heating resistance but increases the risk of leakage from the tank through the mounting hole or holes of these devices for holding this heating resistance.
- Another known solution consists in fixing by welding in a tank, a retaining member which ensures that the end of a heating resistance protrudes inside of this tank.
- This retaining member is constituted by a part formed by a succession of curved U-shaped parts, the recesses of which are alternately turned upwards and downwards.
- the parts of this retaining member having their recesses open upwards are welded to the tank and those having their recesses facing down serve to apply the heating resistance against the tank.
- the bottoms of the U-shaped parts having their recesses facing down are provided with elastic tongues which ensure that this heating resistance is applied against the tank and thus make it possible to avoid their trepidation.
- the aim of the present invention is to avoid these drawbacks, which makes it possible to produce an apparatus with a motor and a liquid tank provided with a heating resistor which does not generate noise during the operation of the apparatus and which does not require for its installation only one fixing hole drilled in the wall of the tank, which thus makes it possible to minimize the risk of leakage from the tank and / or to remove the devices for holding or retaining this heating resistance against the tank.
- an apparatus with a motor and a liquid tank provided with at least one heating resistor mounted through a passage hole formed in the side wall of this tank to protrude therein and have ends which leave the tank fixed in a leaktight manner at this hole by means of a seal device, tightened by a tie rod and a clamping nut mounted on this tie rod, characterized in that it comprises a position lever mounted on the ends of this resistance projecting towards the outside of the tank, producing in its combination with the elastic seal of this seal device an off-center clamping effect giving this seal a double function, that to ensure a seal at the fixing of the heating resistance and to ensure a firm application of this heating resistance against the bottom of the tank, to form between this tank and the resistance a rigid mechanical assembly.
- an appliance with a motor and a liquid tank, provided with a heating resistor can be a washing machine for the laundry schematically illustrated in FIG. 1, or a washing machine for the dishes not shown, or any other appliance. comprising a liquid tank provided with at least one heating resistance, and operate under the action of a motor.
- the device 1 shown, as an example, in Figure 1, is a washing machine comprising a liquid tank 2, a heating resistor 3 mounted near the bottom of this tank 2, a washing drum 4 and a motor 5.
- the heating resistor 3 may have the shape of a coil illustrated in FIG. 1 or the shape of a rod, a pin or any other shape, not shown.
- the resistance 3 is fixed on the side wall of the tank 2 so that its heating body is inside this tank and its ends allowing the electrical supply connections are protruding towards the outside of the tank through a passage opening 6 formed in the wall of this tank.
- the resistor 7 is fixed in a leaktight manner to the side wall 10 of the tank, by means of, on the one hand, an elastic seal 14 and a cup 13 applied against the outer surface of the edge of the opening 11 of the tank 9, and on the other hand, an elastic sheath 15 and a tight tie 16, using a nut 17, against the inner surface of the edge of the opening 11 of the tank 9.
- the di spositif 18 which holds the body of the resistor 7 consists of a clip mounted through a hole 19 drilled in the bottom 8 of the tank and fixed by a nut 20.
- An elastic seal 21 seals the hole 19 of the tank 9. During the operation of the device, the vibrations of the drive motor are transmitted to the tank 9 and the resistance 7.
- the clip 18 prevents the resistance 7 in its vibration from touching the bottom 8 of the tank 8 and eliminates a source of noise. Note, however, that the presence of the hole 19 in the bottom 8 creates an additional risk of leakage from the tank 9, adding to that created by the opening 11 formed in the side wall 10 of this tank.
- the invention advantageously eliminates this additional risk often encountered in known devices.
- the apparatus comprises a liquid tank and a heating resistor whose body is forced to assume a more or less inclined position so as to be firmly and freely applied against the bottom of the tank, which constitutes a permanent support, and the ends for the power supply connections are hermetically fixed in an opening in the side wall of the tank.
- the apparatus comprises, a liquid tank 22 and a heating resistor in the form of a coil 23.
- the end of the heating resistor 23 are fixed in an opening 24 from the side wall of the tank 22, for example by means of an elastic seal 25 clamped between a cup 26 and the head of a tie rod 27, the ends of the heating resistor 23 which pass through the cup 26 being made hermetic and rigidly secured to this cup 26 by welding, crimping or any other known technique.
- These fastening elements, namely the cup 26, the seal 25 and the tie rod 27 cooperate, with a position lever 28 and the bottom 29 of the tank 22, in the establishment of the resistor 23 so as not to require , as in a fixing device of conventional type (FIG. 2), drilling a hole 19 in the bottom of the tank 22.
- the position lever 28 is constituted by a U-shaped part provided with parallel branches of unequal lengths -30 and 31, and in the bottom, with a hole 32 for the passage of the rod of the tie rod 27.
- the hole 32 preferably has , a diameter markedly greater than that of the rod of this tie rod to give the latter a great freedom of orientation movement.
- the lever 28 is mounted on the rod of the tie rod 27, with its short branch 31 applied to the upper half of the cup 26 relative to this tie rod 27, and its long branch 30 resting on the wall of the tank 22 which is located in below this drawing.
- the lever 28 is tightened against the tank 22 and the cup 26 by a nut 33 mounted on the rod of the tie rod 27.
- the upper half of the cup 26 is thus closer to the wall of the tank 22 than the lower part of this cup.
- the cup 26 which is rigidly secured to the resistor 23 consequently inclines the latter towards the tank 22 and applies it firmly against the bottom of the latter, this bottom constituting a permanent support for this resistor.
- the heating resistor 23 and the tank 22 then form a rigid mechanical assembly and the heating resistor 23 is forced to vibrate in block with the tank 22 during the operation of the not shown motor of the device. The inconvenience of the annoying noise generated by repeated mechanical shocks between the heating resistor and the vibrating tank is thus avoided.
- the position lever consists of a part L 34, one of the ends of which is provided with a hole 35 for passage with clearance of the rod of the cooperating tie 27, and the other end carries a spacing adjustment screw 36.
- the lever 34 is mounted between a tightening nut 33 and the cup 26, with its adjusting screw end resting on the wall of the tank being located below the tie rod 27 and its other end resting on the upper half of this cup relative to this tie rod.
- the resistor 23 thus forms the tank 22 a rigid mechanical assembly.
- This mechanical connection between the resistor 23 and the bottom 29 of the tank can be reinforced by bosses 37 formed in this bottom 29, on either side of the path traced by the body of this resistor. In fact, these bosses 37 not only increase the rigidity of the bottom 29 of the tank 22 but also constitute stops preventing any possible lateral movements of the heating resistance 23.
- the position lever is constituted by a flat radial tab 28 of the cup 26, which extends the plane of the bottom of the cup 26.
- This tab 38 is provided at its end with a spacing adjustment screw 39.
- the cup 26 with its tab 38 is tightened against the elastic joint 25 by a nut 40, screwing onto the rod of the tie rod 27.
- the end of the tab 38 bearing the screw 39 is spaced from the wall of the tank 22, which is located below the tie rod 27, plus the upper half of the cup 26 diametrically opposite to this lug 38 is brought closer to the wall of the tank, relative to its half lower.
- the cup 26 which is rigidly secured to the heating resistance 23 inclines this resistance towards the tank and applies it firmly against the bottom 29 of the latter.
- the heating resistor 23 then forms with the tank 22 a rigid mechanical assembly which vibrates as a unit during the operation of the not shown motor of the device.
- the position lever consists of a longitudinal lug 41 of the cup 26, which extends its edge.
- the cup 26 with its longitudinal lug 41 is tightened against the elastic seal 25 by the nut 40 mounted on the rod of the tie rod 27.
- the more the tightening of the nut 40 the more the upper half of the cup 26 diametrically opposite to the lug 41 is brought closer to the wall of the tank, the lug 41 being in abutment against the wall of this tank which is below the tie rod 27.
- the cup 26 which is rigidly secured to the resistor 23, inclines this resistor towards the tank 22 and applies it firmly against the bottom 29 of the latter.
- the heating resistor 23 then forms with the tank a rigid mechanical assembly which vibrates as a unit, during the operation of the not shown motor of the device.
- bosses 37 formed in the bottom 29 of the tank also provide the same functions as those indicated in the variant shown in FIG. 4.
- the apparatus produced according to the invention thus has a simple and economical structure and comprises a minimum risk of leakage and noise.
