Detailed Implementation

[0031] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please refer to Figures 2 to 9 This utility model provides an oven equipped with a single burner.

[0033] like Figure 2 As shown, the oven includes an oven body 1, which includes an oven shell 11 installed on the outside and an oven cavity 12 installed inside. The oven cavity 12 is installed inside the oven shell 11 and is connected to the oven shell 11. It is also connected to the outside through the oven shell 11, thereby introducing fresh air into the oven cavity 12. At this time, the air is cold air containing oxygen. After being heated by the burner 2, it forms hot air. The hot air heats the side guide plate 52 and bakes the food from top to bottom.

[0034] like Figure 2As shown, a burner 2 is installed at the lower part of the oven cavity 12. In this embodiment, only one burner 2 is used, which is a single burner 2. An upper baffle 51 is installed above the burner 2. The burner 2 heats the upper baffle 51. After being heated, the upper baffle 51 radiates infrared light onto the bottom of the food to heat the bottom of the food. At the same time, the upper baffle 51 blocks the flame of the burner 2, thereby preventing the food from directly contacting the flame.

[0035] Furthermore, side guide plates 52 are installed on both sides of the upper baffle 51. The side guide plates 52 are connected to the bottom of the upper baffle 51. The burner 2 generates a heat source through combustion. The heat source is divided into a first heat source that heats the upper baffle 51 and hot air that enters the side guide plates 52 as a second heat source.

[0036] Furthermore, the first heat source heats the upper baffle 51, and the heated upper baffle 51 radiates infrared light onto the bottom of the food to heat the bottom of the food.

[0037] The second heat source heats the side guide plate 52, and the heated side guide plate 52 radiates infrared radiation to the side of the food, thus heating the bottom side of the food.

[0038] The upper part of the oven cavity 12 is equipped with a top diversion plate 53, and the end of the side guide plate 52 corresponds to the top diversion plate 53. The hot air (second heat source) output from the end of the side guide plate 52 is guided by the top diversion plate 53 to the middle of the oven cavity 12 to bake the food from top to bottom with hot air; thus, it has two heating functions: hot air baking and infrared radiation.

[0039] like Figure 4 and Figure 5 As shown, in order to connect the side guide plate 52 with the bottom of the upper baffle 51, the upper baffle 51 is provided with a number of louver holes 511 on both sides. The louver holes 511 are arranged in an orderly manner in the horizontal and vertical directions to realize the output and connection of the second heat source. The lower part of the side guide plate 52 covers the louver holes 511, and the louver holes 511 input the second heat source to the side guide plate 52.

[0040] like Figure 3 As shown, there are two side guide plates 52, which are respectively arranged on the left and right sides of the oven cavity 12. The side guide plates 52 are U-shaped and are arranged upward along the side of the oven cavity 12. A U-shaped flow channel is formed between the side guide plates 52 and the oven cavity 12. The second heat source is input from the bottom of the oven cavity 12, flows through the side of the oven cavity 12, and is output from the top of the oven cavity 12. After being guided by the top diversion plate 53, it flows to the middle of the oven cavity 12.

[0041] Furthermore, when the second heat source flows through the side guide plate 52, it heats the side guide plate 52, so that the heated side guide plate 52 can emit infrared radiation to heat the bottom side of the food.

[0042] like Figure 3 As shown, the side guide plate 52 includes a bottom cover 521 covering the louver hole 511, a side cover 522 covering the side of the oven cavity 12, and a top cover 523 covering the top of the oven cavity 12; the top cover 523 is provided with a first inclined guide plate 524 at its end for inclinedly guiding the output of the second heat source; the first inclined guide plate 524 is inclined downward, which helps the second heat source to flow to the middle of the oven cavity 12.

[0043] Correspondingly, such as Figure 3 As shown, the top diversion plate 53 includes a first inclined diversion plate 531 installed on one side and a second inclined diversion plate 532 installed on the other side. The first inclined diversion plate 531 and the second inclined diversion plate 532 are both corresponding to the first inclined guide plate 524. The first inclined diversion plate 531 and the second inclined diversion plate 532 are both inclined downwards and cooperate with the first inclined guide plate 524 to help the second heat source flow to the middle of the oven cavity 12.

[0044] Furthermore, such as Figure 3 As shown, the included angle between the first inclined diverter plate 531 and the second inclined diverter plate 532 is between 90 degrees and 160 degrees. When the included angle is too small, the first inclined diverter plate 531 and the second inclined diverter plate 532 will occupy most of the space, and the guiding effect will be better. When the included angle is too large, the first inclined diverter plate 531 and the second inclined diverter plate 532 will not occupy the upper space, and the guiding effect is also average. In this embodiment, the included angle between the first inclined diverter plate 531 and the second inclined diverter plate 532 is 150 degrees.

[0045] like Figure 6 As shown, the lower part of the oven cavity 12 is provided with a receiving groove 61, the upper part of the receiving groove 61 is provided with an upper baffle 51, and the burner 2 is installed inside; the receiving groove 61 and the upper baffle 51 form a combustion chamber.

[0046] like Figure 6 As shown, the burner 2 includes a delivery pipe 21 for gas delivery and a plurality of ignition holes 22 disposed on both sides of the delivery pipe 21. The delivery pipe 21 is L-shaped, and the plurality of ignition holes 22 are arranged longitudinally along the delivery pipe 21. An ignition needle 24 is provided at the end of the ignition hole 22. The ignition needle 24 is mounted on the receiving groove 61 and is used to ignite the gas.

[0047] In other embodiments, multiple burners 2 may be provided, arranged horizontally; existing finished products may also be used directly.

[0048] like Figure 9 As shown, the bottom of the upper baffle 51 includes a third inclined diverter plate 513 installed on one side and a fourth inclined diverter plate 512 installed on the other side. The third inclined diverter plate 513 and the fourth inclined diverter plate 512 correspond to the ignition hole 22 and guide the gas flame to burn on both sides, thereby forming a second heat source.

[0049] like Figure 8 As shown, the oven cavity 12 is connected to the outside through the oven shell 11 for drawing in air; as Figure 7 As shown, the oven cavity 12 is provided with a smoke exhaust channel 13, which is used to exhaust air; thereby realizing the circulation and exchange of internal air and external air.

[0050] Furthermore, such as Figure 8 As shown, the lower part of the receiving groove 61 is provided with several first waist-shaped through holes 91, which enable the receiving groove 61 on the oven cavity 12 to communicate with the oven shell 11; the rear part of the oven shell 11 is provided with several vertically arranged second waist-shaped through holes 92, which enable the oven shell 11 to communicate with the outside world and realize the automatic flow of air.

[0051] Furthermore, the air circulation is as follows: First, external cold air enters the oven shell 11 through the second waist-shaped through-hole 92, and then enters the receiving groove 61 through the first waist-shaped through-hole 91; second, the burner 2 heats the cold air inside the receiving groove 61, and the cold air also provides a certain amount of oxygen to help the burner 2 burn combustible gases, such as natural gas; third, the heated hot air is guided by the third inclined diverter plate 513 and the fourth inclined diverter plate 512, enters the side guide plate 52 through the louver hole 511, and exits from the end of the side guide plate 52, and flows to the middle of the oven cavity 12 after being guided by the top diverter plate 53; finally, the hot air is discharged through the exhaust channel 13.

[0052] The oven equipped with a single burner can eliminate the existing upper burner installed on the upper part of the oven cavity 12, but can still retain the original hot air baking and infrared radiation functions, so that the food can be heated evenly from all directions and the baking effect is better. The oven body 1 has both hot air baking and infrared radiation functions.

[0053] The heating process of food in the oven body 1 is as follows: The burner 2 heats the upper baffle 51 to form a first heat source. The heated upper baffle 51 then radiates infrared radiation to the bottom of the food, heating the bottom of the food. The burner 2 heats the air to form hot air, which enters the side guide plate 52 to form a second heat source. As the second heat source flows upward, it heats the side guide plate 52. The heated side guide plate 52 then radiates infrared radiation to the sides of the food, heating the sides of the food. Simultaneously, the second heat source flows upward along the side guide plate 52 and is output to the upper part of the oven cavity 12. It is then guided by the top diverter 53 to the middle of the oven cavity 12, where the food is baked from top to bottom with hot air. Thus, it has both hot air baking and infrared radiation heating functions.

[0054] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
