Description

paired with the vacuum cleaner.

  The present invention relates to a canister type vacuum cleaner and more particularly to a canister type vacuum cleaner comprising a device

  used to deliver an electrolytic liquid.

  Generally, a canister type vacuum cleaner includes a vacuum cleaner body having a drive motor for producing a suction force, a suction extension tube connected to the vacuum cleaner body and a brush. aspiring willing to

  end of the extension tube for suction.

  A dust chamber is provided in the body of the vacuum cleaner and contains a filter unit and a

  dust container. Therefore, pol-

  the particles coming from the surface to be cleaned are entrained by the suction force of the drive motor by being introduced into the dust chamber after having passed through the suction brush, having been filtered in a filtering device and after having been collected in

the dust container.

  The suction extension tube has a handle with an on / off switch. Therefore when the user grasps the handle and moves the suction brush along the surface to be cleaned, polluting substances such as dust or foreign substances located on the surface to be cleaned are entrained through the suction brush and therefore removed from the surface to be cleaned. However, stubborn stains on the floor or on a carpet cannot be cleaned by the suction force of the drive motor and therefore a brush applied to the floor or to fabrics or a rotating brush is fitted. so that you can turn in the suction brush to clean the stained areas Another suggestion is to send a cleaning liquid containing a detergent to clean the areas which are difficult to clean by the rotary brush or the brush applied on the floor or on fabrics. However, in the context of the suggestion made above, it is necessary to carry out a step of preparing a cleaning liquid consisting in diffusing a certain amount of detergent in water, which is inconvenient to use by a user

the cost increases.

  Another problem is that the areas to be cleaned are frequently stained again by the

wasted cleaning fluid.

  The present invention has been developed to eliminate the problems of the prior art mentioned above. This is why an object of the present invention is to provide a vacuum cleaner of the canister type perfected so as to clean the stains on the floor or a carpet-without

  use detergent, but using a simple process.

  The objective indicated above is achieved using a canister type vacuum cleaner, characterized in that it comprises a vacuum cleaner body comprising a drive part for producing a suction force, and a dust chamber. used to collect pollutants which are entrained by the suction force of the drive part, an extension tube for the suction connected to the body of the vacuum cleaner, a suction brush arranged at one end of the extension tube for the suction used to entrain polluting substances from a surface to be cleaned by means of the suction force which is applied via the extension tube for suction, and an electrolytic liquid supply device, mounted on the extension tube for suction, to spray an electrolytic liquid on the surface to be cleaned through a

  lower side of the suction brush.

  According to another characteristic, the spraying unit comprises a supply path connecting the electrolytic liquid production unit and the air suction orifice of the suction brush, a spraying pump arranged on the path feed, and a spray nozzle formed at one end of the feed path for spraying the electrolytic liquid at the suction port

  the box type vacuum cleaner in Figure 1.

  The preferred embodiment of the present invention will be described in more detail with reference

to the accompanying drawings.

  Referring to Figure 1, the canister type vacuum cleaner according to the preferred embodiment of the present invention includes a vacuum cleaner body 10, a suction extension tube 20 connected to the body 10 of the vacuum cleaner, suction brush 30 disposed on one end of the extension tube for suction 20 and an electrolytic liquid feed device arranged on the extension tube for suction 20. As in a conventional type vacuum cleaner, the body 10 of the The vacuum cleaner comprises a drive unit and a dust chamber, which are formed respectively inside this body. The drive unit has a drive motor for producing a suction force. A dust collection filter or cyclone dust collection device is arranged in the dust chamber for filtering substances

  pollutants from the intake air.

  If the suction brush 30 acts so as to entrain liquids in addition to the polluting substances, it may include a liquid separation unit so as to collect the liquid separately from the polluting substances. As mentioned earlier, this is the medium that is generally used in the vacuum cleaner of the

  wet-working type, the description of which will not be

not given here.

  The suction extension tube 20 is connected to the body 10 of the vacuum cleaner and includes a flexible hose 21, a suction hose 23 connected to the flexible hose 21 and a handle 25 disposed between the hose 21 and the suction tube. suction 23. The suction tube 23 has an arrangement which makes it possible to selectively increase its length. The suction brush 30 is mounted so as to

  be movable on one end of the suction tube 23.

  Referring to Figure 2, the suction brush 30 has an air intake port 31, through which substances

  pollutants from the surface to be cleaned are vacuumed

  Rees. A rotary brush 33 can also be arranged.

  ment on the air intake port 31. The rotary brush 33 performs the cleaning operation in a flapping motion against the surface to be cleaned, while being driven in rotation by the suction force or by a separate driving force. The electrolyte supply device The liquid 40 causes an electrolytic liquid to be cleaned on the surface to be cleaned by means of the suction brush 30 to clean the carpet or the floor. The supply device 40

  electrolytic liquid has a dispensing unit 41

  supply of the electrolytic liquid formed in the suction tube 23, and a spraying unit 43 used to spray the electrolytic liquid produced in the unit 41 for producing the electrolytic liquid on the surface to be cleaned through the air suction orifice 31 of the

suction brush 30.

  The electrolyte liquid production unit 41 is well known in the art and an example

  typical is shown in Figure 3.

  Referring to Figure 3, the electrolytic liquid production unit includes a raw water tank 51 used to contain water such as tap water, fresh water, water natural, etc., a spout 52 for bringing the raw water from the raw water tank 51, a filter 53 for filtering the raw water which has passed through the pump 52, first and second electrolytic baths 54 and 55 and

an electrolyte tank 56.

  The filter 53 separates, by filtration, ions and impurities from the raw water. The raw water, which has passed through the filter 53, enters the first electrolyte bath 54. The first electrolyte bath 54 has a cathode plate 54a and an anode plate 54b. The first electrolyte bath 54 performs the electrolysis of the raw water and

  sends the resulting water to the second electrolyte bath 55.

  The second electrolytic bath 55 also has a cathode plate 55a and an anode plate 55b. The second electrolyte bath 55 serves to additionally electrolyze the water which does not yet contain electrolyte and produce

  therefore an NaCIO electrolytic liquid.

  In addition, gaseous substances (usual-

  hydrogen gas) are produced in the first and second electrolyte baths 54 and 55. To eliminate the

  gaseous substances, a separate unit can be provided.

  Although this represented embodiment of the first and second electrolytic baths 54 and 55 used, the

  number of baths can be higher or lower depending on

tion of situations.

  Then, an electrolytic liquid produced in the second electrolytic bath 55 is sent to the tank

electrolyte 56 and stored there.

  A mixing bath 57 can also be provided to temporarily store the raw water which has passed through the filter 53. In this case the mixing bath 57 receives a catalyst from an additive reservoir 58, which is - provided separately. The catalyst can be liquid sodium chloride or liquid sodium and calcium chloride or liquid calcium chloride. Depending on the situation, an appropriate type of catalyst can be chosen. Therefore, a mixture of catalyst and raw water is sent from the mixing bath 57 to the first bath.

  The electrolyte 54 and underwent electrolysis in this bath.

  The previous description concerning unit 41

  electrolytic liquid production is only one example of the well known means of producing electrolyte liquid and it will be noted that different variants are possible. Furthermore, the electrolytic liquid spraying unit 43 includes a path 61 for supplying the electrolytic liquid which connects the electrolyte reservoir 56 and the air suction orifice 31 of the suction brush, a spray pump. 63 disposed on the path 61 for supplying the electrolytic liquid and a spray nozzle 65 formed on one end of the path 61 for supplying the electrolytic liquid. The spray pump 63 pumps the electrolytic liquid from the liquid stored in the electrolyte reservoir 56 so that the electrolytic liquid can be sprayed onto the surface to be

  clean, using spray nozzle 65.

  The canister type vacuum cleaner comprising the electrolytic liquid supply device, arranged as in the preferred embodiment of the present invention sprays the electrolytic liquid produced in the

  device 30 for delivering the electrolytic liquid directly

  tion from the outside through said orifice

  suction 31 of the suction brush 30.

  Under the effect of the electrolytic liquid,

  stained locations are cleaned. The electrolyte liquid

  tick is also usable for water treatment

  used or as a bleaching agent for fabrics

  cotton, as a disinfectant for food

  tion in water, as a bactericidal agent, etc., and can clean even stubborn old stains on the surface to be

  clean, without using an additional detergent.

  It is not necessary to dissolve the detergent in the raw water and, since it is not necessary

  to use detergent, the cost also goes down.

  In addition, as shown in FIG. 4, when the suction brush 70 fitted with a fabric for contacting the ground 71 at its underside is mounted on the suction tube line 23, the electrolyte liquid, which is delivered on the path 61 for supplying the electrolytic liquid, is applied to the fabric 71 coming into contact with the ground. Since the fabric coming into contact with the ground is impregnated with the electrolytic liquid, the cleaning operation can be performed

effectively.

  Although the purported embodiment of the present invention has been described, those skilled in the art will understand that the present invention is not limited to the preferred embodiment described and that various changes and modifications may be made therein.
