  • the heat energy saved by utilizing the atomizer may be used to produce more steam
  • the atomizer may be embodied as a spray nozzle device that has a small opening.
  • the fluid velocity at the exit pipe 13 may also be high which may cause the fluid to split into a plurality of small droplets thus creating the fine mist.
  • the atomizer 15 may limit the possibility of fluid exiting with steam generated in the second steam chamber 2.
  • a second steam (B) may exit the second steam chamber 2 via the outlet pipe 16 and may enter the exemplary mechanical valve assembly 17.
  • the steam (B) may have properties different than steam (A).

  • the base 4 may include the heating element 5 and the second steam chamber 2, which may be defined by a top part or element 7, and a bottom part or element 8.
  • a fastening system such as, e.g., but not limited to, a screw assembly 9 may couple the top and bottom parts 7, 8 together.
  • the heating element 5 may heat the top part 7 to warm the fluid in the first steam chamber 1 and may also heat the contents in the second steam chamber 2.
  • a second heating element 26 may be provided for heating the first steam chamber 1 or the second steam chamber 2.
  • the second steam chamber 2 may be defined by corresponding channels formed in the top and bottom parts 7, 8 of the base 4. Alternatively, the channels may be positioned in a middle part (not shown) with the top part 7 and the bottom part 8 serving as covers.
  • the path of the heating element 5 may track the channels formed in the top and bottom parts 7, 8. In this way, the heating element 5 may heat the contents of the second steam chamber 2 while heating the fluid in the first steam chamber 1.
  • the second steam chamber 2 may be designed to have the longest possible path available to provide the maximum length possible between inlet 10 and an outlet 11 for the conversion of all the fluid/mist into steam.
  • the second steam chamber 2 may have a shortened path to allow a smaller percentage of evaporation of the fluid. This embodiment may allow a fine mist of fluid to exit with the steam created in the second steam chamber.
  • the exit pipe 13 may couple to the inlet 10 so that fluid from the first steam chamber 1 may enter or be injected to the second steam chamber 2 after passing through the atomizer 15.
  • the atomized fluid that is injected into the second steam chamber 2 may be converted to steam by the end of the second steam chamber 2.
  • the channel width of the second steam chamber 2 may be narrow or may narrow to facilitate the conversion of substantially all the fluid into steam.
  • the second steam chamber 2 may include sharp directional changes wherein the passage may turn with a small radius direction change.
  • the second steam chamber 2 may have capture pockets 21 A, 21B, 21C, and 21D (collectively 21) where fluid can collect.
  • the capture pockets 21 may purposely create turbulence points within the passage to trap any fluid droplets that may be transferred along with the steam moving at a high velocity.
  • the fluid which is heavier than the steam, may be unable to turn within the passage and may remain trapped in the capture pockets 21 without the possibility to move until the fluid is converted into steam (B).
  • Once the fluid inside the pockets is converted into steam (B), the pressure inside the second steam chamber 2 may increase due to the fluid to steam conversion process.
  • the steam (B) in the passage may travel toward the steam outlet 11.
  • An outlet pipe 16 (see Figs. 1 and 4) may connect or couple to the steam outlet 11 to channel the steam (B) away from the second steam chamber 2.
  • the outlet pipe 6 from the first steam chamber 1 and the outlet pipe 16 from the second steam chamber 2 may both be coupled to an exemplary mechanical valve(s) assembly 17.
  • the mechanical valve assembly 17 may allow the release of steam (A) or steam (B).
  • the mechanical valve assembly 17 may also allow the steam (A) and the steam (B) to mix in order to form a hybrid steam (C).
  • Steam cleaning is an example of using a high velocity moist steam.
  • the hybrid steam (C) may be used.
  • the steam (A), steam (B), or hybrid steam (C) may exit the mechanical valve assembly 17 through a common output conduit 22 which may be coupled to the mechanical valve assembly 17.
  • An exemplary micro-switch 19 may control the power supply to the pump 14. When the micro-switch 19 is depressed, power may be sent to the pump 14. The pump 14 may channel the fluid at the predetermined temperature from the first steam chamber 1 to the second steam chamber 2. The control cam 20 may depress the micro-switch 19 to turn the power on for the pump 14.
  • the valve 18 may be manually or automatically controlled and may control the position of the control cam 20.
  • the valve 18 also may control the steam passed from outlet pipes 6 and 16 to the common output conduit 22.
  • the embodiment depicted in Figures 4-6 shows the valve 18 with three positions. However, the valve 18 may alternatively be embodied with a single or other positions.
  • Figure 4 shows an exemplary first position of the valve 18. In the first position, the mechanical valve assembly 17 may accept steam (A) from the first steam chamber 1 and may output the steam (A) via the common output conduit 22. In the first position, the control cam 20 may not contact the micro-switch 19 and the pump 14 may be off.
  • the valve 18 may shift to a third position and the control cam 20 may contact the micro-switch 19.
  • the mechanical valve assembly 17 may accept the steam (B) from the second steam chamber 2 via outlet pipe 16 while outlet pipe 6 is closed. Since the steam (A) may not exit the first steam chamber 1 through the outlet pipe 6 in this position, the pressure in the first steam chamber 1 may increase.
  • the pressure switch (not shown) may be used to reduce the pressure generated in the steam chamber 1.
  • the common output conduit 22 may release the steam (B) in this third position.
  • the valve 18 may have two positions.
  • a first position may allow just one of the steam (A) or steam (B) to exit.
  • both the steam released in the first position and the steam not released in the first position may both be released. Accordingly, the steam released in the first position may always be released regardless of the first or second position.
  • the steam output may be controlled in a range from of a predetermined minimum single release of steam to a maximum hybrid steam (C) of both steam (A) and steam (B).
