Description

    FIELD OF THE INVENTION
  • The present invention relates to a multi-layer heating apparatus, more specifically to be mounted on a steam cooker or a deep fryer.
  • DESCRIPTION OF PRIOR ART
  • Steaming is a cooking method that utilizing extreme hot steam, generated by heating water with a burner provided under, to heat the food. Steaming is considered as a healthy way to cook the food as it preserves the nutrition within the food and keeps the meal in low fat. However, steaming consumes more energy comparing to other method because most of hot steam is expelled outside the cooker after passing the food with huge amount of heat remains therein. Through the years, inventions have been disclosed for improving the efficiency of the steam cooker, such as the cited document 1, U.S. Pat. No. 6,098,527, entitled “Structure of a steaming apparatus”, invented by the very same inventor of the present invention. The cited document 1 teaches a steam cooker having a water boiler and a burner placed under. The water boiler composed of an inner and outer channel with multiple pipes provided therein. The lateral walls of the inner channel and pipes can transfer the heat, reducing the boiling time of the water. Further, the boiler is sealed by a pressure-tight cover having tubes to eject steam. The temperature inside the cooker is increased as the pressure rises, with tubes eject steam toward the food, thus, the cooking time is reduced evidently.
  • Even though the device disclosed above increases the efficiency, the gas produced by the burner, however, is led toward the outside directly through a vent line provided between the inner and outer channel. The gas contains huge amount of heat and is completely wasted. Therefore, to use the heat from the gas combining the structure disclosed previously to improve further the efficiency of the steam cooker has become the main objective of the present invention.

  • DETAIL DESCRIPTION OF PREFERRED EMBODIMENTS
  • The preferred embodiments of the present invention are described in detail hereinafter according to the appended drawings.
  • As shown in FIGS. 1-3, a multi-layer heating apparatus can be realized by comprising a heating unit (1), an accumulator (2) provided externally and attached to the heating unit (1) for supplying or refilling the liquid (water or oil) that needs to be heated. The liquid (6) required to be heated is placed on a top of the heating unit (1), and a heating source (7) can be provided on a bottom thereof. As the liquid contained in said accumulator can be either water or oil, the claimed heating apparatus can be applied to variable cooking means, i.e. steam cabinet, pasta cooker or even deep fryer.
  • At least one air conduit tube (3) is provided on an upper portion of the heating unit (1) for leading the gas produced during the heating process. Said tube (3) is extending toward the outside of the heating unit (1) by passing through the outer wall thereof and connects to a fume vent (4). The fume vent (4), as illustrated in FIGS. 5 and 6, extends upwardly along a side wall of a cooking device (5) which carried the heating unit (1) and having its terminal (51) set on the top of the device (5).
  • Referring to FIGS. 2-4, said air conduit tube (3) is preferably set on the top of the heating unit (1), either contacting directly or spaced by a predetermined distance; at least one through hole (31) is defined on the wall of said air conduit tube (3) for transferring liquid. The through hole (31) is set perpendicular to the flow direction of the liquid, and a diameter thereof is smaller than the air conduit tube (3).
  • Pluralities concavities (32) are provided on a surface of said air conduit tube (3). The concavities (32) are spaced with each other by a predetermined distance and arranged in pluralities of rows, and said rows are arranged in a staggered formation. The concavities (32) create additional heating surfaces, and with the shape to slow the flow rate, the temperature of the tube body is raised for heating the liquid above more efficiently.
  • FIG. 2 showing pluralities of holes (113) are set on the outer side wall of the heating unit (1). Said holes (113) allow the air conduit tubes (3) to pass and connect with the fume vent (4). At least one orifice (41) is provided on a lower section of said fume vent (4), where closer the heating unit (1) is preferable for introducing the cool air into the vent (4) and increasing the convection.
  • FIG. 5 illustrates a partial sectional view of the vent (4). The fume vent (4) is consisted of a metallic inner tube (42) and an outer insulation layer (43) covering said inner tube (42) in order to prevent the staff be harmed by the hot air whether the fume vent (4) is concealed or exposed to the cooking device (5).
  • Referring to FIGS. 4 and 6, said heating unit (1) consists of an outer casing (11), an inner casing (12), which is set within the outer casing (11), having a plurality of hot water tubes (121) provided horizontally therein, an inlet tube (13) provided between said outer casing (11) and the accumulator (2), and at least one outlet tube (14) connected to the outer casing (11). Said outer casing (11) comprises a square hollow portion (111) and a tapered opening (112) attached to a top of said square portion (111). Although the hollow portion (111) is defined to have a square shape, a cylindrical shaped is also allowed. The bottom portion of said hollow portion (111) is coupled to a bottom of the inner casing (12) and a top of said tapered opening (112) is coupled to an inner wall of the heating apparatus.
  • The inlet tube (13) and said tapered opening (112) are joined by a first relief pipe (15) to balance the pressure of the accumulator (2). An upper opening of the first relief pipe (15) should be higher than a liquid surface (6). Functioning as communication tube, the liquid inside first relief pipe (15) is automatically delivered to the heating unit (1) as the liquid surface (6) drops.
  • A second relief pipe (16), for relieving the internal pressure of the cooking device (5), is penetrating a side wall of an upper portion of the heating unit (1) and joins to the accumulator (2).
  • Said hot water tubes (121) are arranged in pluralities layers, and each layer consists of a plurality of tubes (121) spaced by a predetermined distance. As shown in FIGS. 3 and 4, the tubes of one layer are perpendicular with tubes of a lower layer, which means that hot water tubes (121) of each odd layer (layer 1, 3, 5 etc.) are arranged in a same fashion while hot water tubes (121) of each even layer (layer 2, 4, 6 etc.) are arranged in the same fashion.
  • The claimed heating apparatus can be applied to variable cooking means. FIGS. 7 and 8 demonstrate two possible applications of the apparatus. FIG. 7 shows the cooking device (5), which the partial view thereof has been shown in FIGS. 5 and 6 is a steam cabinet, for steam cooking dumpling or steamed bun, while FIG. 8 showing the cooking device (5) as a deep fryer, commonly utilized in fast food restaurant for frying chicken, fries or chips.
