Description

    BACKGROUND OF THE INVENTION
  • A common conventional liquid heating device generally includes a cast block 1 made of zinc-aluminum alloy and an electric heating tube 10 and a water conveying tube 11 both contained in the cast block 1. Then the cast block 1 is heated up by the electric heating tube 10, and then the water conveying tube 11 is heated up by the heat of the cast block 1 so that liquid flowing in the water conveying tube 11 is also heated up to become airy vapor. The time required in vaporizing may be 2 - 3 minutes at least or more than ten minutes at latest depending on the capacity of the electric heating tube 10. If liquid in the tube 11 is to be vaporized in two or three minutes, the heating tube should be large enough to heat up swiftly and accordingly use a large amount of electricity. If liquid is to be heated up in 10 - 20 minutes, the heating tube can be small to use small amount of electricity, but it takes time, not convenient to use.
  • The conventional liquid heating device described above uses the electric heating tube 10 for indirectly heating liquid flowing through the water conveying tube 11, having inferior effect in vaporizing due to insufficient heat capacity so that liquid drops may remain at the outlet of the water conveying tube 11, hardly meeting the using standard.
  • The U.S. PAT NO.4,246,871 has a water heater 10 surrounding a chamber 20, which then helically located around an outlet 30 so that the water heater 10 may heat the water in the chamber 20. So it is complicated, attaining its object and effect by processing the chamber 20 to surround the water heater 10.
  • Next, U.S. PAT NO.5,058,194 has a heating tube 14, and an electric resistance 17 wound on the surface of the heating tube 14. The electric resistance 17 produces high temperature to heat the water in the heating tube 14, impossible to produce steam instantly, as it is an indirect heating mode.
  • Document US-A-6 189 453 discloses a liquid heating device according to the preamble of independent claim 1.
    • SUMMARY OF THE INVENTION
  • This invention has been devised to offer a liquid heating device capable to produce vapor quickly, applicable to various industries. The invention is disclosed in the appended independent claim 1.
    • BRIEF DESCRIPTION OF DRAWINGS
    • Figure 1 is a side view of a conventional liquid heating device;
    • Figure 2 is a perspective view of a liquid heating device in the present invention;
    • Figure 3 is a perspective view of a helical heating tube in the present invention; and,
    • Figure 4 is a perspective view of vapor produced by the helical heating tube in the present invention.
    DETAILED DESCRIPTION OF THE INVENTION
  • A preferred embodiment of a liquid heating device in the present invention, as shown in Fig. 2, includes a pump 2, a heating tube 3 and a control system 6 as main components combined together.
  • The pump 2 has an inlet tube 20 fixed on a side of the pump 2 for pumping in liquid in a liquid store tank (not shown), and an outlet tube 21 connected to the heating tube 3.
  • The heating tube 3 is shaped helical, having an inlet end 31 connected with a connect tube 30, and an outlet end 32 passing through a tube clamp 4 consisting of two leading wires 40 as shown in Figs. 3 and 4. Then two electric wires 50, 51 are respectively connected to the connect tube 30 and the tube clamp 4.
  • The control system 6 is used to control electric power to be supplied to the two electric wires 50, 51 to electrify and heat up the heating tube 3 to directly heat up liquid therein quickly to high temperature so as to vaporizing liquid at the outlet end 32. In other words, instant electrifying carries out immediate heating to a proper temperature, boiling or vaporizing..
  • The helical heating tube 3 has an advantage that much liquid flows in the helical heating tube 3, the pump 2 produces pressure for pushing forward liquid in the heating tube 3, and vapor produced may be swiftly pushed out of the outlet end 32. On the other hand, liquid of room temperature flows at first in the helical heating tube 3 to keep the liquid in the inlet end 31 at the lowest temperature, increasing swiftly its temperature as it moves forward in the tube 3. Then the liquid may ultimately become vapor or boiled or reach to a proper temperature at the outlet end 32. Therefore, the temperature at the inlet end 31 is maintained low, preventing liquid in the tube 3 from flowing back to the pump 2, and consequently keeping smooth forward flowing of liquid in the heating tube 3. In addition, the liquid heating device in the invention does not have problems of drops occurring or of imperfect vaporization.
  • Therefore, the liquid heating device is applicable to a drinking water dispenser or a water heater or the like, owing to its function of heating liquid swiftly to boil, to vaporize, or to obtain proper temperature, worthy to be utilized in various industries.
  • While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the scope of the invention as disclosed in the claims.
