Patents Act 1990 COMPLETE SPECIFICATION IP Aust INNOVATION PATENT L 7 NOV SMOKELESS STOVE USING INFRARED The following statement is a full description of this invention, including the best method of performing it known to me: 01 t' z TITLE: SMOKELESS STOVE USING INFRARED SBACKGROUND OF THE INVENTION 2(a) Technical Field of the Invention o The present invention generally relates to stoves, and more particularly to a smokeless stove using infrared for grilling and having an internal basin for collecting the dripping grease.

Description of the Prior Art Food cooking using traditional electric stove usually requires experience for setting up the power and cooking time appropriately. For an inexperienced user, he or she usually has to make frequent checks to the cooked food during the process, which is quite troublesome. On the other hand, a grill is commonly used for barbecue, in which the food is placed on a gridiron and is broiled by the coal below. As such, the barbecue sauce and the grease from the food would drip on the burning coal, which not only extinguishes the coal but also causes quite some greasy smoke blended with ashes from the burning coal.

To avoid the smoke, some people would place the coal not directly below the food on the gridiron. However, the cooking effect is of course compromised this way. It is also quite well known to most people that the greasy smoke is not only polluting but also harmful to the user's health. The 0 Z 2 traditional coal-based stove or grill is also difficult to clean.

Z 3 t\q SUMMARY OF THE INVENTION C€3 C€3 SThe primary purpose of the present invention is to a smokeless stove to 2obviate the foregoing shortcomings of conventional coal-based stoves and Sgrills.

The smokeless stove mainly contains a gridiron, a pair of infrared heaters, a pair of stove walls, a holding plate, and a water basin. The use ofinfi-ared, compared to using traditional fuels such as coal, has a number of advantages such as no ashes to stain the cooked food, very easy cleaning, and no need to worry about improper burning and fire hazard. This is one of the objectives of the present invention.

The water basin is positioned on the holding plate and both are positioned right beneath the gridiron to collect the barbecue sauce and grease dripped from the cooked food. The infrared heaters are arranged around the water basin so that they radiate infrared upward slantwise toward the gridiron. The dripping barbecue sauce and the grease wouldn't stain the infrared heater and the greasy smoke commonly found in traditional coal-based stove or grill is thereby avoided. This is another objective of the present invention.

Yet another objective of the present invention is that water vapor produced from the water inside the water basin help to keep the cooked food moist and to add flavor to the cooked food.

The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become Sapparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.

Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

6 t' DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention.

Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

FIG 1 is a perspective viewing showing the smokeless stove according to a first embodiment of the present invention. FIG 2 shows the smokeless stove of FIG 1 with its cover opened, while FIG 3 shows the various components of the smokeless stove of FIG 1. As illustrated, the smokeless stove 10 mainly contains a gridiron 20, at least a pair of stove walls 30 facing toward each other, at least a pair of infrared heater 40 facing toward each other, a holding plate 51, and a water basin The stove walls 30 are at the left and right sides of the stove 10, each of which has a flange 30A configured along the inner surface and across the middle section of the stove walls 30. The gridiron 20 is placed on the flanges Beneath the flange 30A, each of the stove walls 30 has a trapezoid-shaped bottom half 31 having a larger top along the flange 30A and 7 t-,

a smaller bottom. Each of the two infrared heaters 40 has its two ends O arranged along the corresponding slant sides of the two opposing 2trapezoid-shaped bottom halves 31 so that the heating surfaces 42 and 43 of Sthe infrared heaters 40 face upward slantwise and toward the gridiron The holding plate 51 is placed at the bottom of the stove 10 and could be slid in and out of the bottom of the stove 10. On the other hand, the water basin is placed on top of the holding plate 51, which is right beneath the central space 32 confined by the stove walls 30 and the infrared heaters 40. At the side of the stove 10 facing the user, a door 11 is configured to provide access to the water basin 50. As shown in FIG 3, there are multiple tubular elements 51A on top of the holding plate 51 for accommodating corresponding pins 50A at the bottom of the water basin 50 so as to position the water basin 50 in its place.

As shown in the cross-section diagram of FIG 4, the infrared generated by the heaters 40 is directed slantwise toward the gridiron 20 and its surrounding space. As such, the barbecue sauce and the grease from the food 60 on the gridiron 20 would drop into and be collected and cooled down by the water in the water basin 50 without staining the heating surfaces 42 and 43 of the infrared heaters 40 and the bottom of the stove 10. The greasy smoke commonly found in coal-based stoves and grills is thereby prevented Z8 by the present invention. In addition, water vapor from the water contained in the water basin 50 would help to moist the cooked food 60, making it more 2delicious and adding to its flavor.

FIG 5 shows another embodiment ofthe present invention. As illustrated, instead of using tubular elements 5 1A, the holding plate 51 is configured with multiple pin holes 51IB for receiving the pins 50B at the bottom of the water basin 50. Compared to the traditional stoves and grills, the present invention is extremely easy to clean. The user simply takes out the water basin 50 through the door 11, washes the water basin 50, and uses a dry cloth to wipe clean the inside of the water basin It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
