Description

Technical Field

[0001] The utility model relates to baking equipment, in particular to a baking oven. Background Art

[0002] The baking oven mainly uses smoke input into the interior to bake and smoke the food placed inside. The current baking oven is usually a box-shaped structure with an air inlet on the bottom side and an air outlet on the top side. The smoke enters the baking oven from the air inlet, passes through the food inside the baking oven from bottom to top, and is discharged from the air outlet. Since the smoke stays in the baking oven for a limited time, the efficiency of heating the food with the smoke is low. Therefore, a baking oven with higher heating efficiency is urgently needed. Utility Model Content

[0003] The utility model aims to provide a baking oven to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] A baking oven comprises: an outer shell, wherein a cavity is arranged inside, an air inlet is arranged on the bottom side, and an air outlet is arranged on the outer side of the top; a partition layer is formed in the cavity, the partition layer divides the cavity into an upper cavity and a lower cavity, the middle part of the partition layer protrudes upward to form a boss, and a connecting hole is arranged on the top side of the boss; a support net is located in the upper cavity, and the support net extends around the boss.

[0006] This technical solution has at least the following beneficial effects: when in use, food is placed on the support net of the upper cavity, and smoke enters the lower cavity from the air inlet on the bottom side of the outer shell. At this time, the smoke can heat the partition layer, so that the bottom surface of the food is subjected to the heat radiation of the partition layer, and part of the smoke enters the partition layer upwardly at the internal position of the boss, and enters the upper cavity from the connecting hole. At this time, the smoke diffuses to the surroundings in the upper cavity, heats the food on the support net, and is finally discharged outward from the air outlet. In this way, the upper cavity and the lower cavity are arranged in the baking oven, which prolongs the internal flow distance and time of the smoke, improves the heat exchange efficiency of the smoke, and thus enhances the baking effect of the food.

[0007] As a further improvement of the above technical solution, the shell includes an upper cover, a furnace body and a base connected in sequence from top to bottom, the air inlet is formed on the bottom side of the base, the air outlet is formed on the outside of the upper cover, the upper cavity is formed between the upper cover and the furnace body, the lower cavity is formed between the furnace body and the base, and the partition layer is formed on the bottom side of the furnace body. The shell mainly includes an upper cover, a furnace body and a base arranged in sequence from top to bottom to form an upper cavity and a lower cavity. After the smoke enters the lower cavity between the base and the furnace body from the air inlet on the bottom side of the base, it enters the upper cavity between the base and the upper cover through the connecting hole on the bottom side of the furnace body, and finally is discharged from the air outlet on the outside of the upper cover.

[0008] As a further improvement of the above technical solution, the middle part of the bottom side of the base is convex upward to form a gas gathering groove, and the air inlet is formed at the bottom of the gas gathering groove. When in use, the external fire source or smoke source is located at the gas gathering groove, which can better gather the smoke and discharge it into the lower cavity from the air inlet, thereby reducing smoke leakage, further reducing energy consumption, and improving heat utilization.

[0009] As a further improvement of the above technical solution, the upper cover and the furnace body, and the furnace body and the base are detachably connected. The upper cover and the furnace body, and the furnace body and the base can be detached from each other, so as to selectively open the upper cavity or the lower cavity, which is convenient for subsequent use and maintenance.

[0010] As a further improvement of the above technical solution, the outer side of the bottom of the furnace body is convex inwards and forms a concave angle on the outer side of the furnace body, the concave angle extends around the outer periphery of the furnace body, and the top side of the base is inserted into the concave angle. The outer side of the bottom of the furnace body is concave inwards to form a concave angle. When the furnace body and the base are spliced ​​together, the top side of the base is inserted into the concave angle, so that the two can be quickly connected and positioned, and the assembly is convenient.

[0011] As a further improvement of the above technical solution, the position of the inner side of the furnace body corresponding to the concave angle is a convex angle, and the support net is located at the top side of the convex angle. The furnace body forms a convex angle at the inner side of the concave angle formed inwardly, and because the concave angle extends around the outer periphery of the furnace body, the convex angle also forms an annular convex structure in the furnace body. When the support net is placed in the upper cavity, the convex angle can be used to support and position the outer side of the support net, which is more convenient to use.

[0012] As a further improvement of the above technical solution, the bottom side of the upper cover is provided with an annular hook edge extending inward, and the top side of the furnace body is inserted upward into the annular hook edge. When the furnace body and the upper cover are assembled with each other, the annular hook edge on the bottom side of the upper cover is inserted into the furnace body, and the upper cover and the furnace body can be quickly assembled by using the mutual cooperation of the two, which is highly practical.

[0013] As a further improvement of the above technical solution, the inner diameter of the boss gradually decreases upward. The space formed by the partition layer on the inner side of the boss gradually decreases from top to bottom, so that the smoke is gradually compressed when entering the connecting hole upward, increasing the pressure of the smoke passing through the boss, and releasing the smoke pressure to the surroundings when entering the upper cavity from the connecting hole, which is conducive to a more uniform temperature distribution in the upper cavity and improves the baking effect.

[0014] As a further improvement of the above technical solution, a lifting block is connected to the top side of the upper cover, and a temperature detector is arranged in the lifting block, and the temperature detector is used to detect the temperature in the upper cavity. The temperature in the upper cavity can be monitored in real time by the temperature detector, so as to better control the smoke supply amount.

[0015] As a further improvement of the above technical solution, the lifting block is detachably connected to the upper cover. The upper cover can be removed from the lifting block, thereby facilitating maintenance or replacement of the internal temperature detector and improving the convenience of subsequent operation and use.

[0024] Reference Figure 1 and Figure 2 A baking oven comprises a shell, a partition layer and a support net 200, wherein a cavity is arranged inside the shell, an air inlet 131 is arranged on the bottom side of the shell, and an air outlet 111 is arranged on the top outer side of the shell; a partition layer is formed in the cavity, and the partition layer divides the cavity into an upper cavity and a lower cavity from top to bottom, and a boss 123 is protruded upward in the middle part of the partition layer, and a connecting hole 121 is arranged on the top side of the boss 123; the support net 200 is located in the upper cavity, and the support net 200 extends around the boss 123.

[0025] As can be seen from the above, when in use, food is placed on the support net 200 of the upper cavity, and smoke enters the lower cavity from the air inlet 131 on the bottom side of the shell. At this time, the smoke can heat the partition layer, so that the bottom surface of the food is subjected to the heat radiation of the partition layer, and part of the smoke enters the partition layer upward at the internal position of the boss 123, and enters the upper cavity from the connecting hole 121. At this time, the smoke diffuses to the surroundings in the upper cavity, heats the food on the support net 200, and is finally discharged outward from the air outlet. In this way, the upper cavity and the lower cavity are arranged in the baking oven, which prolongs the flow distance and time of the smoke inside, improves the heat exchange efficiency of the smoke, and thus enhances the baking effect of the food.

[0026] The outer shell can be a main body that is enclosed to form a certain space, and an independent layer structure is arranged in the main body to form a partition layer. The space in the main body is divided into an upper cavity and a lower cavity by the partition layer. In order to put in or take out food in the space, an openable and closable cover and other structures can be provided on the main body. In order to facilitate the modular assembly of the whole and manage the upper cavity and the lower cavity separately, in this embodiment, the outer shell includes an upper cover 110, a furnace body 120 and a base 130 connected from top to bottom in sequence, the air inlet 131 is formed on the bottom side of the base 130, and the air outlet 111 is formed on the outside of the upper cover 110. The upper cavity is enclosed between the upper cover 110 and the furnace body 120, and the lower cavity is enclosed between the furnace body 120 and the base 130, and the partition layer is formed on the bottom side of the furnace body 120. The outer shell is mainly composed of an upper cover 110, a furnace body 120 and a base 130 which are arranged in sequence from top to bottom to form an upper cavity and a lower cavity. The smoke enters the lower cavity between the base 130 and the furnace body 120 from the air inlet 131 on the bottom side of the base 130, passes through the connecting hole 121 on the bottom side of the furnace body 120, enters the upper cavity between the base 130 and the upper cover 110, and is finally discharged outward from the air outlet 111 on the outside of the upper cover 110.

[0027] The bottom side of the base 130 can be a plane, and the air inlet 131 can be set on the plane. In order to better gather the smoke, in this embodiment, the middle part of the bottom side of the base 130 is convex upward to form a gas gathering groove 132, and the air inlet 131 is formed at the bottom of the gas gathering groove 132. When in use, the external fire source or smoke source is located at the gas gathering groove 132, which can better gather the smoke and discharge it into the lower cavity from the air inlet 131, so as to reduce the leakage of smoke, further reduce energy consumption, and improve heat utilization.

[0028] In the above embodiment, the furnace body 120 and the base 130 can be an integrally formed structure, or the two can be fixed to each other by welding, rivets, etc., and the furnace body 120 and the upper cover 110 can be disassembled from each other, so as to facilitate the taking and placing of food. In order to further improve the convenience of overall disassembly and assembly, in this embodiment, the upper cover 110 and the furnace body 120, and the furnace body 120 and the base 130 are detachably connected, for example, the upper cover 110 and the furnace body 120 can be connected to each other by buckles or threads, and the furnace body 120 and the base 130 can also be connected to each other by buckles or threads. The upper cover 110 and the furnace body 120, and the furnace body 120 and the base 130 can be disassembled from each other, so as to selectively open the upper cavity or the lower cavity, which is convenient for subsequent use and maintenance.

[0029] As a specific way of detachably connecting the furnace body 120 and the base 130, the outer side of the bottom of the furnace body 120 is convex inwards and forms a concave angle on the outer side of the furnace body 120, and the concave angle extends around the outer periphery of the furnace body 120, and the top side of the base 130 is inserted into the concave angle. The outer side of the bottom of the furnace body 120 is concave inwards to form a concave angle. When the furnace body 120 and the base 130 are spliced ​​together, the top side of the base 130 is inserted into the concave angle, so that the two can be quickly connected and positioned, and the assembly is convenient.

[0030] In the above embodiment, the support net 200 can be directly placed on the inner bottom side of the furnace body 120, but at this time, it is difficult for the smoke to flow to the bottom of the support net 200 to heat the food. Therefore, the support net 200 can be raised to facilitate the smoke to flow to the bottom of the food and improve the heating effect. In order to facilitate the lifting and positioning of the support net 200, in this embodiment, the position of the inner side of the furnace body 120 corresponding to the concave corner is a convex corner 122, and the support net 200 is located on the top side of the convex corner 122. The furnace body 120 forms a convex corner 122 at the inner side position of the concave corner formed inwardly. Since the concave corner extends around the outer periphery of the furnace body 120, similarly, the convex corner 122 also forms an annular convex structure in the furnace body 120. When the support net 200 is placed in the upper cavity, the convex corner 122 can be used to support and position the outer side of the support net 200, which is more convenient to use.

[0031] In practical applications, since the support net 200 extends around the boss 123, the position of the support net 200 can be further limited by the support net 200 abutting against the outer position of the boss 123, thereby improving the stability of the placement of the support net 200. The support net 200 can be a plurality of circular rings, and connecting rods are connected between the plurality of circular rings to connect the plurality of circular rings together.

[0032] As a specific way of detachably connecting the furnace body 120 and the upper cover 110, the bottom side of the upper cover 110 is provided with an annular hook edge 112 extending inward, and the annular hook edge 112 is a flange formed by bending the bottom side of the upper cover 110 toward the center of the upper cover 110, and the end of the flange is further bent downward to form a position for cooperating with the top side of the furnace body 120, and the top side of the furnace body 120 is upwardly inserted into the annular hook edge 112. When the furnace body 120 and the upper cover 110 are assembled with each other, the annular hook edge 112 on the bottom side of the upper cover 110 is inserted into the furnace body 120, and the upper cover 110 and the furnace body 120 can be quickly assembled by using the mutual cooperation of the two, which is highly practical.

[0033] The boss 123 may be a straight cylindrical structure. In order to make the smoke more evenly distributed when entering the upper cavity, in this embodiment, the inner diameter of the boss 123 gradually decreases. The space formed by the partition layer inside the boss 123 gradually decreases from top to bottom, so that the smoke is gradually compressed when entering the connecting hole 121 upward, increasing the pressure of the smoke passing through the boss 123. When entering the upper cavity from the connecting hole 121, the smoke pressure is released to the surroundings, which is conducive to a more even temperature distribution in the upper cavity and improves the baking effect.

[0034] The top side of the boss 123 may be curled inwardly, thereby improving the anti-deformation capability of the boss 123 and making the overall structure more stable.

[0035] In order to facilitate the placement and removal of the upper cover 110, in this embodiment, a lifting block 300 is connected to the top side of the upper cover 110, and a temperature detector 310 is arranged in the lifting block 300. The temperature detector 310 is used to detect the temperature in the upper cavity. The temperature detector 310 can be a thermometer or an electronic temperature meter, etc. The temperature in the upper cavity can be monitored in real time by the temperature detector 310, so as to better control the smoke supply amount.

[0036] In some embodiments, the lifting block 300 is detachably connected to the upper cover 110. For example, the bottom side of the lifting block 300 can be fixed to the upper cover 110 by a snap connection, or fixed to the upper cover 110 by a threaded connection. The upper cover 110 can be removed from the lifting block 300, so as to facilitate the maintenance or replacement of the internal temperature detector 310, thereby improving the convenience of subsequent operation. In practical applications, the upper cover 110 has a downwardly opening space inside, and the temperature detector 310 can be installed in the upper cover 110, and a avoidance port is set at the position of the upper cover 110 facing the temperature detector 310, so that the temperature detector 310 can extend into the upper cavity from the avoidance port, further improving the accuracy of the temperature measurement inside the upper cavity.

[0037] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
