- - Figures 10 to 12 are sections of the flexible hose equipping the device for adjusting the liquid of the preceding figures, when the adjusting knob is respectively minimum steam position in the maximum steam position and intermediate position.
- Figures 1 to 3 show a steam stripping apparatus comprising a body 1 of plastic comprising an elongate portion forming a handle receiving a removable water tank 2 whose upper wall is the upper part of the handle.
- the elongated part of the body 1 jully, an electric pump 3, visible in Figure 3, whose start is controlled by a control button 4.
- the body 1 comprises, in the extension of the handle, a portion of greater width containing a steam generator 5, visible in Figure 3; conventionally constituted by an instantaneous vaporization chamber associated with an electric heating element 6.
- the body 1 of the apparatus is closed, opposite the handle, by a flat face 7 having steam outlet holes 70, the body 1 advantageously receiving a removable brush 8 having multiple flexible fingers extending to the periphery of the flat face 7 and allowing the application of traction on the fibers during the diffusion of steam through holes 70 to promote degreasing.
- the electric pump 3 comprises an inlet orifice 30 connected by a duct 9 to the tank 2 and comprises a discharge orifice 31 sending the water coming from the tank 2 through a feed circuit of the tank 2.
- steam generator 5, diagrammatically illustrated in FIG. 4 comprising a duct 10 leading to a branch dividing the supply circuit into a first duct branch 11 connected to an inlet orifice 50 of the steam generator 5 and a second branch pipe 12 connected to the tank 2 for discharging a portion of the water from the pump 3 to the tank 2.
- the first pipe branch 11 has a passage section smaller than that of the second pipe branch 12, the first pipe branch having for example an inner diameter of about 1 mm and the second pipe branch 12 having for example an inner diameter of about 2 mm.
- the second pipe branch is constituted by a flexible pipe 12, for example rubber, which passes through a cylindrical housing 13 comprising means for compressing the flexible pipe 12 to reduce the cross section of the latter and control the amount of water discharged to the tank 2.
- the cylindrical housing 13 is composed of two parts 13A, 13B of plastic fixed to one another by means of elastic claws 131, the lower portion 13A of the housing comprising a channel 132 for receiving the hose 12 having a lateral opening facing the means for compressing the pipe 12 consisting of a lever 133 having a bent part bearing against the outer surface of the flexible pipe 12.
- the lever 133 is advantageously obtained directly from molding with the lower portion 13A of the cylindrical housing and has an end articulated to the periphery of the housing 13 and a free end extending close to the center of the housing 13.
- the lower parts 13A and upper 13B of the housing comprise a central opening 134A, 134B receiving the shaft 140 of a rotary knob 14 coming to cover the upper part 13B of the housing projecting from the body 1 of the apparatus, the shaft 140 being provided with cams 141 coming from pushing the lever 133 towards the hose 12 during the rotation of the shaft 140 so that the bent portion of the lever 133 compresses the hose 12.
- the upper portion 13B of the housing comprises a housing 135 for receiving a locking pin 16 brought by a spring 160 against the inner surface of the rotary knob 14, the latter having three cavities 142 in which can engage the end of the pin 16 to immobilize the button 14 in three predefined positions corresponding respectively to a minimum, average and maximum flow rate of steam production of the steamer.
- the flexible hose 12 contains numerous filaments 15 of circular cross-section of small diameter, preferably of the order of 0.2 mm, extending freely inside the internal diameter of the pipe. flexible 12, these filaments 15 being preferably made of polyamide material.
- the flexible pipe 12 may have an outer diameter of about 4 mm for an inner diameter of about 2 mm and will contain ten eight filaments 15 having a length similar to the length of the hose 12.
- the number of filaments 15 inserted into the hose 12 will depend mainly on the inner diameter of the latter and will advantageously be between ten and twenty-five filaments, the number of filaments 15 being preferably adapted so that the filaments 15 occupy between 10 and 30% of the passage section of the hose 12 when the latter is not deformed.
- the start of the electric pump 3 by means of the button 4 causes the suction of the water from the tank 2 by the first duct 9 and the water delivery through the second duct 10, the flow of water.
- water emitted through this second duct 10 being divided between a first relatively small flow sent through the first branch 11 to the steam generator 5 and a second, larger flow of water, sent through the hose 12 towards the tank due to the large passage section left free on both sides of the filaments 15.
- the steam generator 5 is then fed with a low flow of water through the first pipe branch 11, which allows operation of the steamer with a low steam flow.
- the button 14 can also be brought to an intermediate position, in which it is locked in position by the cooperation of the peg 16 with the central groove 142 of the button 14. In this position, the crushing of the hose 12 is such that its height is reduced by half, as is illustrated in Figure 12, and the passage section through flexible hose 12 provided with the filaments 15 becomes of the order of 1 mm 2 .
- Such an intermediate position of the knob 15 makes it possible to obtain an average pressure drop across the hose 12 so that the flow of water sent to the steam generator 5 corresponds to a mean steam flow rate.
- Such a device in which a hose is clamped to modify its passage section, has the advantage of allowing the adjustment of the steam flow of the steaming device by a simple and economical mechanical system to achieve.
- such a device makes it possible to modify the steam flow of the apparatus without affecting the power supply of the pump.
- the presence of filaments in the flexible pipe has the advantage of allowing a more gradual reduction of the passage section of the pipe and therefore better control of the flow therethrough.
- a device has the disadvantage of providing a little progressive adjustment, the passage section of the pipe decreasing slightly in the first phase of compression of the pipe and much more brutally when the two opposite walls of the pipe come into contact with one another.
- the presence of the filaments in the flexible pipe also has the advantage of avoiding the phenomenon of bonding of the walls occurring when a rubber hose is held pressed for a long time against each other, the filaments preventing the opposite walls of the hose from being in contact when the latter is crushed by the bent portion of the lever.
- the circular section of the filaments makes it possible to limit the contact surface of the filaments between them or with the flexible pipe so that the phenomenon of adhesion is limited, the use of the polyamide material for the filaments also making it possible to prevent the filaments do not stick together.
