Vaporization chamber for a hairstyling appliance that diffuses steam

Abstract

The present invention relates to a vaporization chamber for a hairstyling appliance that diffuses steam, comprising a hollow body defining a free interior space between at least one inlet for feeding liquid water to be vaporized and at least one outlet for the water in the form of steam, said steam chamber being characterized in that the inlet or inlets for feeding liquid water have, together, a plurality of orifices that open into the interior of the vaporization chamber and are spaced apart from one another.

1 . Household electrical appliance that diffuses steam, comprising at least one reservoir ( 300 ) that is able to contain a quantity of a liquid product to be vaporized and is fluidically connected to at least one inlet for feeding liquid product to a vaporization chamber ( 350 ,  400 ,  500 ) that is separate from the reservoir and is able to be fed with liquid product contained in the reservoir via at least one pumping member ( 200 ), the appliance being configured to feed the vaporization chamber with liquid water so as to obtain a steam diffusion flow rate greater than or equal to 0.5 g.min −1  and less than or equal to 5 g.min −1 ,
 said vaporization chamber having at least one outlet for the at least partially vaporized product, which is fluidically connected to steam diffusion orifices ( 130 ) of a treatment surface of the appliance,   the vaporization chamber comprising a hollow body defining a free interior space that is able to allow fluid circulation between the inlet for feeding a liquid product to be vaporized and the outlet for said at least partially vaporized product, said steam chamber being characterized in that the inlet or inlets for feeding liquid product have, together, a plurality of orifices ( 405 ), which each have a section of between 0.1 and 6 mm 2 , open into the interior of the vaporization chamber and are spaced apart from one another, the free interior space not having porous material around said orifices for feeding liquid water over a distance of at least 2 mm so as to allow the liquid water leaving an orifice to arrive directly in contact with at least one evaporation surface of the chamber.   
     
     
         2 . Household electrical appliance according to  claim 1 , characterized in that the inlet for feeding the vaporization chamber ( 400 ) with liquid product is in the form of a pipe ( 401 ) having a terminal part ( 403 ) which extends inside said vaporization chamber and along which a plurality of orifices ( 405 ) are provided in a spaced-apart manner. 
     
     
         3 . Household electrical appliance according to  claim 2 , characterized in that the orifices ( 405 ) are spaced apart regularly. 
     
     
         4 . Household electrical appliance according to  claim 2 , characterized in that the orifices ( 405 ) are distributed substantially along the entire length of the terminal part ( 403 ) of the pipe ( 401 ) forming the feed inlet. 
     
     
         5 . Household electrical appliance according to  claim 2 , characterized in that the terminal part ( 403 ) of the pipe forming the feed inlet has a closed distal end ( 406 ). 
     
     
         6 . Household electrical appliance according to  claim 2 , characterized in that the orifices ( 405 ) are provided along at least two longitudinal axes of the pipe that form, between one another, a non-zero angular sector with a longitudinal central axis of the pipe. 
     
     
         7 . Household electrical appliance according to  claim 6 , characterized in that the orifices ( 405 ) are provided along the two longitudinal axes, at least in the case of some of them, in an alternating manner. 
     
     
         8 . Household electrical appliance  claim 1 , characterized in that the vaporization chamber ( 500 ) comprises a plurality of inlets for feeding liquid product to be vaporized, each feed inlet having at least one orifice opening into the interior of the vaporization chamber. 
     
     
         9 . Household electrical appliance according to  claim 8 , characterized in that the vaporization chamber ( 500 ) comprises at least one inlet for feeding liquid product to be vaporized has a single orifice opening into the interior of said vaporization chamber. 
     
     
         10 . Household electrical appliance according to  claim 9 , characterized in that the orifice of the vaporization chamber ( 500 ) is in the form of an open distal end of the inlet for feeding liquid product to be vaporized. 
     
     
         11 . Household electrical appliance according to  claim 1 , characterized in that at least some of the orifices ( 405 ) of Vaporization chamber ( 400 ,  500 ) that open into the interior of the vaporization chamber, preferably all of the orifices, open at a non-zero distance from internal surfaces of the body forming said vaporization chamber, these internal surfaces comprising the surfaces of peripheral walls ( 503 ,  404 ) and, as the case may be, the surfaces of interior chicanes ( 351 ). 
     
     
         12 . Household electrical appliance according to  claim 1 , characterized in that said appliance is a hairstyling appliance such as a hair brush ( 100 ). 
     
     
         13 . Household electrical appliance according to  claim 1 , characterized in that the steam chamber ( 350 ,  400 ,  500 ), and preferably the reservoir ( 300 ), are incorporated into a portable treatment unit of the appliance, in particular into a handle ( 110 ) thereof.
