Definitions

• the present invention relates to a household appliance which allows whipping the cream, according to the preamble to the claim 1.
• the object of the present invention is to provide a household appliance making it possible to whip without problems even limited quantities of cream and easy to use.
• fig. 1 a partial section through part of a first variant of such an apparatus, at the
• a frame 1 comprising, inter alia, an electric motor 2 and a base plate of the device, not shown.
• On this frame can be mounted an upper part 3 of the device, including, in a rear chamber 10, an eccentric 4, preferably, retractably mounted on an axis 5 of the electric motor 2 and capable of engaging in a transverse oval slot 6 located in the rear part 7a of a piston 7, the middle part 7b of which is housed in " a tube 8.
• the latter can be fixed to the upper part 3 " preferably by means of a ring 9 secured to the tube 8.
• the rear chamber 10, into which the rear part of the piston 7 enters, is preferably separated by a lip seal 11 acting on the piston 7, from the empty volume of the tube 8.
• a channel 12 connecting it to an upright pipe 13 which can be immersed in the liquid cream located in a container, not shown, placed on the base plate of the apparatus.
• a ball valve 14 used to prevent liquid cream drawn into the free volume of tube 8, to be discharged.
• a breakthrough 15 acting according to the Venturi system and serving to draw air into the cream liquid rising through the channel 12 to end up in the free volume of the tube 8.
• a suction is exerted which is due to the fact that the piston 7 is oscillated along its longitudinal axis by the eccentric 4 actuated by the motor electric 2.
• the nozzle 16 preferably has a breakthrough 16a in which the front part 7c of the piston 7 can be guided.
• a center distance X of one to two millimeters is sufficient to guarantee a regular flow of whipped cream at the nozzle 16.
• the upper part 3 of the device can be easily removed from the frame 1, for example using a bayonet coupling.
• the nozzle 16 not being, preferably only jammed on the tube 8, is also removable, so that the piston 7 can be pulled out of the tube 8 forwards.
• all the parts that can come into contact with the cream can be easily accessed. After cleaning, these parts are assembled again and the upper part 3 of the device is re ⁇ mounted on the frame 1.
• the rear part 7a of the piston 7 is preferably provided with a plate 18 cooperating, for this purpose, with a lug 19 formed in the upper part 3 "
• a horizontal breakthrough 26 is provided, ending in a part 27 of the channel 12 being located below the ball valve 14, it preferably mounted in a screw 20.
• a piece including in its external part 21 an air filter 22, through which and through a channel 28, openings 29 and recesses 23 the air is sucked into the opening 26.
• a cone 24, formed on this part serves, in cooperation with the wall of the opening 26, as a regulator of the air volume sucked.
• the lower part 12a of the rising channel of the cream is at the upper end of the pipe 13 and opens immediately after the cone 24 in the opening 26.
• a screw part 25 of the part cited above is still housed, preferably, a screw part 25 of the part cited above.
• the mixture of cream and air enters, at the outlet of the channel 12, into a channel 8a formed either by the tube 8 (fig. 1), or by the upper part 3 of the apparatus.
• This construction of the air suction channel allows the volume of air mixed with the liquid cream to be adjusted as desired, so that the consistency of the whipped cream can be adjusted.
• a seal lip seal 30 is provided between the rear part 7a of the piston and its middle part 7b, so that that this seal, mounted on the piston 7 > supported the suction action exerted by the oscillation of the piston 7 on the cream / - air mixture in the channel 12 as well as the movement of advance of this mixture increasing in volume during its movement towards the nozzle 16.
• the riser can preferably be made of a flexible material, so that containers of various dimensions can be used as "stores" for the liqui ⁇ de cream.
• the apparatus according to the invention is inexpensive in its manufacture and allows without other to whip even very restricted quantities of liquid cream, without great losses.
• the handling of this device is very easy and without any risk, it lends itself well to use in all household kitchens.
