Definitions

  • the invention relates to the field of stain removal.
  • Hydrogen peroxide (H 2 O 2 ) is an oxidizing bleach chemical agent which widely used for disinfecting, medical, and cosmetics.
  • Low concentration hydrogen peroxide (usually less than 10%, 3% and 6% most common) can be directly purchased on shelf for cleaning and hygiene purpose in household.
  • H 2 O 2 solution is a strong oxidant, active to many organic molecules, reducing agent and is also corrosive to many metals, high concentration H 2 O 2 (>40%) can be considered hazardous under certain regulations.
  • Some liquid or gel type of stain removers or laundry detergents also contains certain amount of H 2 O 2 as bleaching agent to remove staining on clothes.
  • the bleaching/oxidizing reaction between H 2 O 2 and stain molecules can be described in general as below.
  • the obtained products of this reaction are oxidized molecules (colorless) and H 2 O.
  • the bleaching reaction is not as effective and requires comparatively long time to diminish the stain color, normally 5 min to 30 min waiting time is needed depends on the stain age and stain type.
  • the stain removal device for treating a stained area on a cloth comprises:
  • the stain removal device for treating a stained area on a cloth comprises:
  • This solution allows removing stain color very fast (in less than 5 min) by heating up the low concentration (for example 3%) of bleach chemical solution, such as H 2 O 2 , after being applied onto the stained area. It is especially effective on stains that can be oxidized like juice, wine, coffee etc.
  • the bleaching/oxidizing reaction rate is greatly enhanced due to the high temperature introduced.
  • One advantage of this solution is that removing stain and drying the stained area on the fabric is done at the same time, no water rinsing is required and no chemical residue is left over on clothes.
  • the absorption component and/or suction fan prevents vapor inhalation and skin contact by user and eliminates any possible health-related side effects.
  • the invention is described using hydrogen peroxide H 2 O 2 as bleach chemical agent.
  • the invention also applies to any bleach chemical agent containing hydrogen peroxide or peroxy acids, or a mixture of both kinds.
  • Fig.1 illustrates the stain removal process according to the invention.
  • First stage S1 H 2 O 2 solution is sprayed on a stained area 101 of a cloth 102.
  • the H 2 O 2 solution oxidizes stain molecules from colored to colorless.
  • Second stage S2 Heating of the sprayed H 2 O 2 solution up to a temperature more than 100 degreeC in order to:
  • Third stage S3 The stained area 101 has been transformed into a colorless area 103, and the cloth 102 is dry. No water rinsing step is needed as there is no chemical residue left over on the cloth 102.
  • Fig.2 depicts a first embodiment of a device 201 according to the invention.
  • the device 201 comprises:
  • the H 2 O 2 vapors are illustrated by arrows directing upward.
  • H 2 O 2 solution is dosed manually by user on the stained area.
  • a container/bottle/cartridge 205 containing H 2 O 2 solution can be used to this end.
  • the heating plate 202 comprises at least one hole 206 (for example in a middle part of the heating plate 202) to let H 2 O 2 vapors pass through.
  • the housing 204 has an opening 207 (for example the diameter of the housing 204) which is larger than the heating plate 202 in order to more efficiently enclose the H 2 O 2 vapors within the housing 204.
  • Fig.3A depicts a second embodiment of a device 301A according to the invention. It is based on the embodiment of Fig.2 .
  • the device 301A further comprises:
  • the absorption component 302 is arranged at a top part of the housing 204.
  • the housing 204 preferably surrounds the absorption component 302.
  • the absorption component 302 aims to prevent H 2 O 2 vapours to propagate around the stain remover device 301A. Indeed, when H 2 O 2 has a high temperature, some H 2 O 2 vapours will be released into air which may result in chemical inhalation and skin contact by user.
  • the absorption component 302 prevents or reduce the possible H 2 O 2 vapors that would be released around the stain remover device 301A otherwise. H 2 O 2 or H 2 O 2 -water vapors can be sucked out by the suction fan 203, and passing through the absorption component 302 and been "trapped" or "quenched".
  • H 2 O 2 vapors and/or water vapors pass through the absorption component 302 arranged at a top part of the housing. H 2 O 2 vapors and/or water vapors are absorbed in the absorption component 302 while passing through it.
  • Fig.3B depicts a device 301B according to the invention corresponding to a modified version of the embodiment depicted in Fig.3A .
  • the suction fan 203 has been removed. Air containing vapors of the bleach chemical solution is no more forced to move towards the absorption component 302. Air containing vapors of the bleach chemical solution is mainly moved by diffusion.
  • This solution has a lower performance compared to the embodiment of Fig.3A in terms of speed of absorbing vapors of the bleach chemical solution, but can still achieve an efficient absorption.
  • Fig.4A depicts a third embodiment of a device 401A according to the invention. It is based on the device of Fig.3B .
  • the device 401A comprises:
  • the vapors are caused to flow around the heated plate 202 within the housing 204, in direction of the absorption component 302.
  • the heating plate 202 comprises a hole 405 (for example in its middle) in order to let the H 2 O 2 solution pass through it and reach the stained area 101.
  • the hole 405 receives the pipe 403.
  • the housing 204 has an opening 207 (for example corresponding to its diameter, if the housing 204 has a cylindrical shape) which is larger than the heating plate 202 to more efficiently enclose the H 2 O 2 vapours within the housing.
  • the heating plate 202 when the heating plate 202 is as large as the opening 207 of the housing 204, the heating plate 202 preferably comprises at least one hole to allow H 2 O 2 vapors and/or water vapors be carried out of the stained area 101:
  • FIG.6B A second embodiment is illustrated in Fig.6B : this embodiment comprises two holes 406B arranged in the heating plate 202.
  • FIG.6C A third embodiment is illustrated in Fig.6C : this embodiment comprises four (partial) holes 406C arranged in the heating plate 202.
  • H 2 O 2 vapors and/or water vapors are carried in the central part of housing 204, around the container 402.
  • the absorption component 302 works same as in the embodiment of Fig.3 .
  • the H 2 O 2 vapors and/or water vapors pass through the absorption component at a top part of the housing.
  • H 2 O 2 vapors and/or -water vapors are absorbed in the absorption component while passing through.
  • any material that is able to absorb water or water vapors or react with H 2 O 2 can be used in the absorption component.
  • materials that absorb water include silica beads (indicating silica), silica gel, calcium sulfate, calcium oxide, calcium chloride, montmorillonite, molecular sieve, etc.
  • Materials that react with H 2 O 2 include active carbon, catalysis like metal ions and enzyme, reducing agent like ferrous sulfate, etc.
  • the absorption component 302 can be formed by or filled-in with a single material mentioned above, or a combination of material mentioned above.
  • Fig.4B depicts a device 401B according to the invention corresponding to a modified version of the embodiment depicted in Fig.4A .
  • the suction fan 203 has been removed. Air containing vapors of the bleach chemical solution is no more forced to move towards the absorption component 302. Air containing vapors of the bleach chemical solution is mainly moved by diffusion.
  • This solution has a lower performance compared to the embodiment of Fig.4A in terms of speed of absorbing vapors of the bleach chemical solution, but can still achieve an efficient absorption.
  • Fig.5 depicts a flow chart of a method according to the invention of treating a stained area 101 on a cloth 102.
