Technical Field

The present invention relates to a heating device, and more particularly, to an infrared reflecting plate of a combustion apparatus for heating an object by using infrared rays.

Background

In a general heating apparatus, a device for providing a heat source generally applies heat energy generated by an open flame to an object to be heated. However, since heat is conducted to the inside of the object via the surface of the object, the object is heated unevenly. For example: during the heating of the food, the heat energy generated by the open fire will be preferentially applied to the surface of the food, and then the heat energy will be gradually conducted to the interior of the food. Therefore, foods often have an overcooked surface and an undercooked interior.

In order to solve the above problems, the current general method is to heat the food by using an infrared heat source by using the characteristic that the infrared wavelength can penetrate the surface of the object, so that the inside and the outside of the food are heated to be consistent. At present, the common way of generating infrared heat source is to use an infrared burner, which is based on the principle that the heat energy of flame is used to heat an infrared generating component, such as a ceramic plate, so that the ceramic plate is heated to generate infrared rays. However, the efficiency of converting the heated ceramic plate into an infrared heat source is limited, and the heating by an open fire cannot be performed, so that the surface of the food cannot be scorched.

Therefore, the design of the existing heating device is still not completed, and there is a need for improvement.

In order to achieve the above object, the present invention provides an infrared reflection plate having a reflection surface for reflecting infrared rays, wherein the reflection surface has a reflection structure, and the reflection structure includes a plurality of protrusions and a plurality of embossings located between the plurality of protrusions.

To achieve the above object, the present invention provides a combustion apparatus, comprising at least one burner having a fire outlet, wherein the at least one burner burns gas and generates flame through the fire outlet; the infrared generating net corresponds to the fire outlet and is provided with a front side surface and a back side surface which are opposite; the infrared generating net is heated by the flame generated by the at least one burner to generate infrared rays; the infrared reflecting plate is arranged on the outer side of the rear side face of the infrared generating net, the infrared reflecting plate is provided with a reflecting surface facing the rear side face, the reflecting surface is provided with a reflecting structure, and the reflecting structure comprises a plurality of convex parts and a plurality of embossings positioned among the convex parts.

as shown in fig. 3, the support assembly 10 includes a front mask 12 and a rear mask 14, wherein the front mask 12 is disposed obliquely and is made of metal. The front mask 12 has a flat and rectangular cover plate 121, and the cover plate 121 has a plurality of holes 124 communicating an outer surface and an inner surface of the cover plate 121. The front mask 12 is disposed obliquely, and the front mask 12 includes a circular wall 13, the circular wall 13 has an upper sidewall 151 connected to the top edge of the cover plate 124, a lower sidewall 152 connected to the lower edge of the cover plate, and two side sidewalls 133 connected to two side edges of the cover plate 121, and the upper sidewall 151, the lower sidewall 152 and the two side sidewalls 133 all have a plurality of holes 124 communicating an inner surface and an outer surface of the circular wall. The annular wall of the front mask 12 extends outward to form a plurality of first extending portions 135, in this embodiment, the first extending portions 135 are respectively located on the upper sidewall 151 and the lower sidewall 152. The cover plate 121 has an opening 122 located near a lower edge of the cover plate 121, and the opening 122 penetrates the inner surface and the outer surface of the cover plate 121.

The rear mask 14 is disposed obliquely and made of metal. The rear mask 14 has a flat and rectangular rear plate 141; the rear mask 14 further includes a ring wall 15 connected to the periphery of the rear plate 141, the ring wall 15 has an upper sidewall 151 and a lower sidewall 152, the ring wall 15 of the rear mask 14 has an upper sidewall 151 connected to the top edge of the rear plate 141, the upper sidewall 151 has a plurality of holes 154 communicating an inner surface and an outer surface of the ring wall 15 of the rear mask 14, the ring wall 15 of the rear mask 14 extends outward to form a plurality of second extending portions 155, in this embodiment, the second extending portions 155 are respectively located on the upper sidewall 151 and the lower sidewall 152.

As shown in fig. 2, the infrared ray generating net 20 is disposed between the front mask 12 and the rear mask 14 of the support assembly 10 and faces the inner surface 121a of the cover plate 121. The periphery of the infrared generating net 20 is extended outward to form a plurality of fixing portions 22 (refer to fig. 3), each fixing portion 22, each first extending portion 135 and each second extending portion 155 correspond, and each fixing portion 22 is sandwiched between each first extending portion 135 and each second extending portion 155, and the front cover 12 and the infrared generating net 20 are fixed to the rear cover 14 by using a bolt, a nut or a welding combination. The infrared ray generating net 20 generates infrared rays by being heated by the flame and is emitted through the holes 154 of the front cover 12; the infrared generating net 20 may be made of ceramic, metal, alloy, etc., and in this embodiment, it is made of ferrochromium alloy.

As shown in fig. 1, the at least one burner 30 has a fire outlet 32, the fire outlet 32 is located below the opening of the cover plate 121, and the infrared ray generating net 20 corresponds to the fire outlet 32; the at least one burner 30 burns gas to generate flame through the fire outlet 32, and acts on the infrared generating net 20; in the present embodiment, the number of the burners 30 is plural, and the flame generated from each of the fire outlets 32 of each burner 30 passes through the opening 122 of the front plate 121 so that the infrared ray generation net 20 corresponding to each of the fire outlets 32 is heated by the flame. However, in practice, only the flame can act on the infrared ray generation net 20, therefore, the burner 30 can also extend into the opening 122, so that the position of the fire outlet 32 can also be located in a chamber formed by the front shield 12 and the rear shield 14 and close to the infrared ray generation net 20.

As shown in fig. 2, the infrared reflection plate 40 is located between the rear mask 14 and the infrared generation net 20, the infrared reflection plate 40 has a flat and rectangular main plate 401 (see fig. 3), the infrared reflection plate 40 is disposed obliquely, the infrared reflection plate 40 further includes a ring wall 41 connected to the periphery of the main plate 401, the ring wall 41 of the infrared reflection plate 40 has an upper side wall 411 connected to the top edge of the main plate 401, and the height of the ring wall 41 of the infrared reflection plate 40 is smaller than the height of the ring wall 15 of the rear mask 14; the infrared reflection plate 40 has a reflection surface 401a and an outer surface 401b, the reflection surface 401a faces the infrared generation net 20, the reflection surface 401a is used to reflect the infrared generated by the infrared generation net 20, so that the reflected infrared passes through the infrared generation net 20 and passes through the holes 124 of the front mask 12. The infrared reflection plate 40 is made of metal, such as stainless steel.

The reflective surface 401a of the infrared reflective plate 40 has a reflective structure 42, the reflective structure 42 includes a plurality of protrusions 421 and a plurality of embosses 422 located between the protrusions 421, the protrusions 421 and the embosses 422 are formed by rolling a metal plate, and the metal plate with the reflective structure 42 is folded into a shape having a main plate 401 and a surrounding wall 41, so that the reflective structure 42 is covered with the entire infrared reflective plate 40. In the present embodiment, the protrusions 421 are tapered and arranged in a matrix (see fig. 4 and 5) or in a staggered arrangement (see fig. 6). The reflective structure 42 is used for reflecting the infrared rays incident on the reflective surface 401a, so that the infrared rays incident on the reflective surface 401a through the infrared ray generating network 20 can be scattered on the infrared ray generating network 20 again, and the infrared ray generating network 20 receives the reflected infrared rays, so that the temperature of the infrared ray generating network 20 is further raised and more heat energy is accumulated, thereby increasing the efficiency of the infrared ray generating network 20 in generating infrared rays.

The burner apparatus of the present embodiment further includes a bracket 50, as shown in fig. 3, the bracket 50 has an upper support plate 52, a middle support plate 54, a lower support plate 56 and a fixing member 58, and the bracket 50 is used to fix the relative positions of the front shield 12, the rear shield 14 and the plurality of burners 30. The middle support plate 54 is fixed between the upper support plate 52 and the lower support plate 56, the fixing member 58 fixes the rear mask 14 to the upper support plate 52 by passing through a fixing hole 59 near the center of the upper support plate, and the plurality of burners 30 are fixed to the lower support plate 56.

Therefore, as shown in FIG. 7, when the flames generated from the fire outlets 32 of the plurality of burners 30 are heated to the infrared ray generation net 20, the infrared ray generating net 20 is heated and generates infrared rays, a portion of the infrared rays are transmitted through the holes 124 of the front mask 12 and emitted, another portion of the infrared rays are emitted toward the reflecting surface 401a of the infrared reflecting plate 40, the reflective surface 401a can uniformly scatter the reflected infrared rays onto the infrared ray generation net 20 by the reflective structure 42, so that the infrared ray generation net 20 can be heated by the reflected infrared rays again, to accumulate more heat energy generated by the infrared ray to the infrared ray generation net 20, so as to raise the temperature of the infrared ray generation net 20, and generates more infrared rays to travel toward the front shield 12 and then pass through the holes 124 of the front shield 12, so as to increase the intensity of the infrared rays applied to the heated object by the burner 100. In practice, the reflection surface 401a may be a plane without the reflection structure 42, and the reflection surface 401a preferably has the reflection structure 42 to achieve the effect of uniformly reflecting the infrared rays to the infrared ray generation net 20. In addition, the front mask 12 is also heated by the flame generated from the flame outlet 32, so that infrared rays are generated and the flame is also emitted from the holes 124 to form an open flame.

It should be noted that, since the front mask 12 is in a flat plate shape, the infrared scattering direction generated by the front mask 12 can be substantially perpendicular to the flat plate-shaped cover plate 121, so that the infrared scattered by the combustion apparatus 100 acts on the object in the same direction, and the infrared intensity received by the object per unit area is more uniform, thereby effectively solving the problem that the intensity of the infrared scattered by the conventional combustion apparatus 100 is uneven due to the mesh structure 42 being in an arc shape.

In addition, the density of the convex portions of the reflective surface 401a of the infrared reflective plate 40 may also be different, wherein the density of the convex portions of the annular wall 41 is greater than the density of the convex portions of the main plate 104. In this way, the combustion apparatus 100 can further enhance the infrared ray accumulation capability near the annular wall 41 due to the density of the protrusions of the annular wall 41, and further, the intensity of the infrared ray generated by the infrared ray generation net 20 becomes more uniform.

Furthermore, the density of the convex portions in a middle area of the main board 401 is smaller than the density of the convex portions in a side area of the main board 401, so that the infrared ray storage capability is gradually enhanced from the middle area to the side area of the main board 401, thereby enhancing the heating degree of the infrared ray generation net 20 in the side area, and making the infrared ray intensity generated by the infrared ray generation net 20 more average.

Still another second embodiment of the present invention, as shown in fig. 8 and 9, is substantially the same as the first embodiment except that the front mask 12 of the first embodiment is not provided, but the infrared ray generating net 20 is directly exposed to the outside; in this embodiment, since the front cover 12 is not provided, each of the fire outlets 32 of each of the burners 30 only acts on the infrared ray generation net 20, so that the infrared ray generation net 20 is heated by the flame and generates the infrared ray; wherein a portion of the infrared rays are directly scattered out of the infrared ray generating net 20 without being blocked by the front cover 12, another portion of the infrared rays are emitted toward the reflecting surface 401a of the infrared reflecting plate 40, and the reflecting surface 401a reflects the another portion of the infrared rays back toward the infrared ray generating net 20 to accumulate more heat energy generated by the infrared rays in the infrared ray generating net 20, so that the temperature of the infrared ray generating net 20 is raised, and more infrared rays are generated to increase the intensity of the infrared rays applied to the heated object by the combustion device 100; therefore, by the design without the front mask 12, the manufacturing cost of the burner 100 can be reduced, and the performance of the infrared heat source of the burner 100 is not affected.

In addition, as shown in fig. 10, an infrared reflection plate 60 of a combustion apparatus according to a third preferred embodiment of the present invention, the structure of the infrared reflection plate 60 is substantially the same as that of the infrared reflection plate 40 of the first embodiment, except that a plurality of holes 614 are formed near the upper sidewall 411 of the infrared reflection plate 60 or the top edge of the main board 601. Therefore, when the flame generated by the fire outlet 32 flows along the reflection surface 601a of the infrared reflection plate 60 to the vicinity of the top edge of the infrared reflection plate 60, the holes 614 can help the flame flowing to the vicinity of the top edge of the infrared reflection plate 60 to flow out along the holes 614 to form open flame, so that the gas flows more smoothly. By means of the holes 614, the flame can heat the infrared generating net 20 and the front mask 12 more uniformly, so that the intensity of the infrared emitted from the combustion apparatus 100 is more uniform. Additionally, the upper sidewall 611 of the infrared reflection plate 60 and the vicinity of the top edge of the main board 601 may have a plurality of holes at the same time.

In addition, fig. 11 shows the infrared reflection plate 90 of the combustion apparatus according to the fourth preferred embodiment of the present invention, in practical implementation, the convex parts 921 of the reflection structure 92 of the infrared reflection plate 90 may also be parallel long strips, and the long axial direction of the convex parts 921 and the long axial direction of the embossings 922 extend from one end 90a of the infrared reflection plate 90 to the other end 90b opposite to the one end in a predetermined direction.

Through the above structure design, the flame can be more uniformly heated on the infrared generation net 20 and the front mask 12 by the reflection structure of the infrared reflection plate, so as to maintain the high temperature of the infrared generation net, and the combustion device can generate infrared rays with higher intensity and more uniformity.

In addition, when the infrared rays are scattered from the holes 124 of the front cover 12 and the front cover 12 itself, the flat plate-shaped cover plate 121 of the front cover 12 is projected in the same direction, so that the intensity of the infrared rays heated per unit area is more uniform.

The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications to the present invention as described and claimed should be included in the scope of the present invention.
