DETAILED DESCRIPTION
[0043] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0044] REFERENCE Figures 1-11 A vertical misaligned heating tube independent heat preservation oven, comprising a vertically arranged, bottom open heat preservation shell 1 and two heating tubes 2 arranged at unequal distances on the two sides inside the heat preservation shell.
[0045] In the conventional arrangement of the heating body of the furnace, the heating tubes are usually arranged uniformly; thus, the temperature near the opening position is low due to fast heat dissipation, while the heat is concentrated inside and the temperature is high; the skewer is prone to the problem of undercooked rear part and overcooked front part; in order to cook the whole skewer completely, more energy needs to be consumed.
[0046] To solve this problem, the heating tubes 2 are arranged at unequal distances; the heating tubes are arranged at reasonable intervals according to the size of the furnace, so that the temperature at each position in the furnace can be controlled to be balanced, the effect of roasting is better, and the energy consumption is reduced.
[0047] Specifically, the arrangement interval of the heating tubes 2 near the inlet and outlet 3 is smaller than that far from the inlet and outlet 3; thus, more heat is released near the inlet and outlet 3 to make up for the heat loss.
[0048] As shown in FIG. Figure 10 It is a top view of the internal structure of the furnace, and the lower side is the direction of the inlet and outlet; the internal space size of the heat preservation shell 1 is 135*165mm (width*depth); two heating tubes 2 are arranged on each side of the heat preservation shell 1; among them, the two heating tubes 2 on the left side are arranged near the middle position, and the two heating tubes 2 on the right side are arranged near the front and rear positions; and the heating tube at the front end on the right side is closer to the inlet and outlet 3, and the preferred interval is 20.5mm; the distance between the heating tube at the front end on the left side and the inlet and outlet 3 is larger, which is 45.5mm; the interval of the two heating tubes 2 on the right side is 110mm, and the interval of the two heating tubes 2 on the left side is 35mm; accordingly, the distance between the rear end heating tube on the left side and the rear wall inside the heat preservation shell 1 is 84.5mm, and the distance between the rear end heating tube on the right side and the rear wall inside the heat preservation shell 1 is 34.5mm.
[0049] It should be noted that the heating pipe 2 is not equidistantly arranged, and the distance is an optimal scheme obtained through multiple tests, calculations and actual effect feedback, and the effect is good, and the roasted skewers are uniform everywhere. It can be understood that under the condition of different furnace models and sizes, the arrangement distance needs to be adjusted correspondingly.
[0050] At the same time, by being arranged in an open bottom mode, the oil and material drops generated during roasting can be discharged in time.
[0051] Correspondingly, a vertical inlet and outlet 3 is arranged on the front side of the heat preservation shell 1, for the entry and exit of skewers.
[0052] It should be noted that the heat preservation shell 1 provided in the application can be used alone or a plurality of heat preservation shells can be arranged adjacent to each other to form a group. The furnace of the application is mainly used for automatic barbecue machines, and is generally used in combination, as shown in Figures 1-2 of course, it can also be independent and used alone.
[0053] As shown in Figures 3-7 The heat preservation shell 1 is assembled by a front shell body 11, a rear shell body 12, a left shell body 13, a right shell body 14 and a top shell body 15, and has an open bottom cuboid shape, and the inlet and outlet 3 is arranged on the front shell body 11.
[0054] At the same time, the front shell body 11, the rear shell body 12 and the top shell body 15 are closed cavity structures, and the inside is filled with heat preservation materials.
[0055] The heat preservation materials can be various common heat preservation materials such as asbestos and rock wool. It should be noted that the cavity structure forms a good closed mode, which fully guarantees food safety. As shown in the drawings, the cavity structure of each shell is made of sheet metal and fully welded to form an internal airtight mode.
[0056] When the heat preservation shell 1 is used alone:
[0057] The left shell body 13 and the right shell body 14 are closed cavity structures, so as to form a complete side + top heat preservation mode.
[0058] When a plurality of heat preservation shells 1 are arranged adjacent to each other to form a group:
[0059] The left shell body 13 of the leftmost heat preservation shell 1 is a closed cavity structure, and the right shell body 14 is a closed cavity structure or a single plate structure; the right shell body 14 of the rightmost heat preservation shell 1 is a closed cavity structure, and the left shell body 13 is a closed cavity structure or a single plate structure; the left shell body 13 and the right shell body 14 of the remaining heat preservation shells 1 are closed cavity structures or single plate structures.
[0060] That is to say, the two left and right shells must be closed cavity structure, and the other left shell 13 and right shell 14 are cavity structure or single plate structure, which can be used.
[0061] Preferably, as shown in the figure, the left and right shells of the inner heat preservation shell 1 are single plate structure, and the gap between the adjacent heat preservation shells 1 is filled with heat preservation material, and the gap is covered with high-temperature resistant material (such as high-temperature resistant aluminum foil) to form a complete closure, thereby further enhancing the heat preservation effect. Figure 9
[0062] Correspondingly, we also design the corresponding assembly structure.
[0063] When the left shell 13 is a closed cavity structure, the left side of the front shell 11 and the rear shell 12 is relatively extended to set a connecting plate and assembled with the left shell 13; the left side of the top shell 15 is extended downward to set a connecting plate and assembled with the left shell 13; that is to say, the left shell 13 is located in the connecting plate of the front shell 11, the rear shell 12 and the top shell 15, and is assembled into one by bolts.
[0064] Correspondingly, when the right shell 14 is a closed cavity structure, the right side of the front shell 11 and the rear shell 12 is relatively extended to set a connecting plate and assembled with the right shell 14; the right side of the top shell 15 is extended downward to set a connecting plate and assembled with the right shell 14.
[0065] Similarly, when the left shell 13 and the right shell 14 are both closed cavity structures, the left side and the right side of the front shell 11 and the rear shell 12 are extended to set a connecting plate; at the same time, the left side and the right side of the top shell 15 are extended downward to set a connecting plate.
[0066] As shown in the figure, when the left shell 13 is a single plate structure, the left shell 13 covers the left side of the front shell 11, the rear shell 12 and the top shell 15, and is assembled by penetrating bolts. Figure 5 As shown in the figure, when the right shell 14 is a single plate structure, the right shell 14 covers the right side of the front shell 11, the rear shell 12 and the top shell 15, and is assembled by penetrating bolts.
[0067] Figure 4 It should be noted that in the scheme provided in the present application, the various shells are assembled by bolts; not only convenient to operate, but also can be quickly disassembled, and the later maintenance and cleaning are very simple.
[0068] In some embodiments, the top of the heat preservation shell 1 is provided with a top hole 9.
[0069] In some embodiments, the top of the heat preservation shell 1 is provided with a top hole 9.
[0070] It should be noted that the top hole 9 avoids the matching position with the crossbeam 8; the opening at the top facilitates the flow of heat energy inside the furnace, further making the temperature inside the furnace more even.
[0071] Preferred, such as Figure 11 As shown, the top hole 9 is square; of course, it can also be round, oval, or other shapes; similarly, it can be a large hole, multiple small holes, or a combination of large and small holes.
[0072] The top hole 9 serves as a heat dissipation hole, forming an upward passage; in conjunction with the bottom opening, heat energy rises during the grilling process; the heat energy inside the oven is distributed from bottom to top, resulting in a more even temperature inside the oven and more uniform heating of the grilled skewers.
[0073] It should be noted that top hole 9 is optional; it can be set or not, depending on actual needs.
[0074] In some embodiments, the lower end of the heat insulation shell 1 is provided with an inwardly inclined oil collection plate 4 on the front and rear sides.
[0075] like Figure 2 , 3 As shown; the two oil collection plates 4 are set opposite each other to prevent oil drips from spilling outwards, and their inclined shape forms a drainage channel to facilitate collection from below.
[0076] In some embodiments, mounting plates 5 are respectively provided on the left and right sides of the lower end of the heat insulation shell 1, and the heating tube 2 is assembled on the mounting plate 5.
[0077] It should be noted that the mounting plate 5 is assembled horizontally, which not only forms the mounting position but also improves the structural strength of the lower end of the insulation shell 1.
[0078] The mounting plate 5 has its two ends bent to form a connecting plate that fits into the inner wall of the insulation shell 1.
[0079] The connecting plate can be bent upwards or downwards to form a vertical surface, fitting snugly against the inner wall of the insulation shell 1; for example... Figure 7 As shown, the connecting plate bends upwards.
[0080] In some embodiments, the heating element 2 on one mounting plate 5 is arranged near the front and rear ends; the heating element 2 on the other mounting plate 5 is arranged near the middle position.
[0081] like Figure 7 As shown, this layout can effectively distribute heat, resulting in a uniform temperature inside the furnace.
[0082] Furthermore, the mounting plate 5 has strip-shaped adjustment holes 6 corresponding to the heating tube 2, which can be easily installed and adjusted to form the most suitable installation shape.
[0083] In some embodiments, the inner side of the mounting plate 5 is downwardly bent and provided with a flow guide strip 7.
[0084] It can be understood that the distance between the vertical heating pipe 2 and the skewers can reduce the attachment of oil stains. However, during the barbecue process, oil dripping and material dripping are inevitable. The mounting plate 5 is relatively more inward, and the oil can be guided by arranging the flow guide strip 7.
[0085] In addition, it should be noted that the extension direction of the flow guide strip 7 is perpendicular to the extension direction of the oil collection plate 4. The two work together to further collect the dripping oil to the middle position.
[0086] In some embodiments, the top of the heat preservation shell 1 is assembled on the cross beam 8 by hoisting bolts.
[0087] As shown in Figure 1 , 2 , the cross beam 8 is directly fixed in the equipment, and the assembly of a plurality of barbecue ovens can be realized.
[0088] When the device is used, skewers are sent from the front inlet and outlet 3. Under the operation of the internally staggered heating pipes, the temperature of each part of the furnace is balanced, and the roasting effect is good. During the roasting process, the falling oil is collected by the flow guide strip 7 and the oil collection plate 4.
[0089] In the utility model, the traditional structure is broken, the heating pipes 2 are not arranged at equal distances and vertically, and are arranged at reasonable intervals according to the size of the furnace, so that the temperature of each part of the furnace is balanced, the barbecue effect is better, and the energy consumption is reduced. It can be used alone or in combination with multiple heat preservation shells, and has a good application range. It is composed of a plurality of closed cavity structures, has good heat preservation effect, and further reduces energy consumption. The shells are assembled by bolts, which is not only convenient to operate, but also can be quickly disassembled, and the later maintenance and cleaning are very simple. The top hole 9 is opened, the heat energy in the furnace body flows from bottom to top, the temperature is more balanced, the skewers are evenly heated, and the consistency is better. The strip-shaped adjusting hole 6 is opened on the mounting plate 5, which is convenient for installation and adjustment, and forms a suitable installation form. The flow guide strip 7 and the oil collection plate 4 work together to collect the dripping oil to the middle position.
[0090] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
[0091] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and the ordinary skilled in the art can change, modify, replace and transform the above-mentioned embodiments within the scope of the utility model.
