Description

Technical Field

[0001] This utility model relates to the field of naan baking technology, specifically a drawer-type naan machine that provides even heating. Background Technology

[0002] Naan is a traditional staple food in Xinjiang and some other Central and West Asian countries and regions. When making naan, wheat or corn flour is first fermented, kneaded into dough, and then baked in a special fire pit (commonly known as a naan oven).

[0003] When baking naan-type foods, they are usually baked in a tandoor oven. Traditional tandoor ovens are generally made of wool and clay or adobe bricks to form a hollow cube. The hollow part is then filled with refractory clay to form a barrel shape that is smaller at the top and larger at the bottom. Alkali clay and mud are then applied to the outside of the refractory clay and air-dried to form the tandoor oven.

[0004] Traditional tandoor ovens have the following problems when baking naan: it is very troublesome to put the naan in and take it out, and it may cause injury to the workers. During the baking process, the naan is prone to uneven heating, which reduces production efficiency. To address this, we propose a drawer-type naan machine that heats evenly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a drawer-type naan bread machine with uniform heating. The heating mechanism enables the naan bread to be heated evenly during the baking process, which speeds up the production efficiency of naan bread. Furthermore, the drawer-type structure of the baking tray and oven body through the pull-out mechanism facilitates the insertion and removal of naan bread, improves work safety, and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drawer-type pancake maker with uniform heating, comprising a furnace body, a heating mechanism, and a pull-out mechanism;

[0007] Heating mechanism: It includes mounting slots, electric heating tubes, refractory bricks, cavities, and insulation cotton. Mounting slots are provided on both the left and right walls of the furnace body, and also on the bottom wall. Electric heating tubes and refractory bricks are installed inside the mounting slots. The refractory bricks are located closer to the center of the furnace body than the electric heating tubes. The electric heating tubes are arranged in a ring. A cavity is provided on the inner wall of the furnace body. The cavity is located further away from the center of the furnace body than the mounting slot. The cavity is filled with insulation cotton. The heating mechanism allows the naan to be heated evenly during baking, thus accelerating the production efficiency of naan.

[0008] Pull-out mechanism: used to slide and limit the baking tray that is slidably connected inside the oven. The inside of the baking tray is lined with evenly distributed refractory bricks. The pull-out mechanism makes the baking tray and the oven body form a drawer-type structure, which facilitates the insertion and removal of naan bread and improves the safety of operation.

[0009] Furthermore, it also includes a controller, which is located on the front side of the upper surface of the furnace body. The input end of the controller is electrically connected to an external power source, and the input end of the electric heating tube is electrically connected to the output end of the controller, so as to facilitate the normal operation of the equipment.

[0010] Furthermore, the pull-out mechanism includes a limiting rod, a limiting seat, and a fixing rod. Limiting rods are provided on both the left and right sides of the bottom wall of the oven body. A baking tray is slidably connected between the two limiting rods. Limiting seats are provided on both the left and right sides of the lower surface of the oven body. The limiting seats are all U-shaped structures with grooves on the lower side. Fixing rods are provided on both the left and right sides of the rear side of the baking tray. The fixing rods are slidably connected to the interior of the adjacent limiting seats to facilitate the sliding and limiting of the baking tray.

[0011] Furthermore, the pull-out mechanism also includes a rotating shaft and a bearing roller. The bearing roller is rotatably connected to the inside of the limiting seat through the rotating shaft. The lower side of the outer surface of the fixing rod is in contact with the bearing groove of the adjacent bearing roller, which facilitates auxiliary support for the baking tray.

[0012] Furthermore, the front side of the baking pan is provided with an clearance groove, and a limit frame is slidably connected inside the clearance groove. A handle is rotatably connected to the front right side of the limit frame. The protrusion on the rear side of the outer surface of the handle is engaged in the slot on the upper side of the front side of the baking pan. Fixing rings are provided on both the left and right sides of the front side of the oven body. The protrusions on the left and right sides of the upper surface of the limit frame are inserted into the interior of the adjacent fixing rings to facilitate fixing the baking pan.

[0013] Furthermore, the interior of the clearance groove is provided with evenly distributed springs, all of which are located between the lower surface of the limiting frame and the bottom wall of the clearance groove, which facilitates the fixing of the baking tray.

[0014] Furthermore, an observation window is provided on the upper front side of the baking pan, and the inside of the observation window is made of high-temperature resistant tempered glass, which facilitates observation of the baking process.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This drawer-type pancake maker with uniform heating has the following advantages:

[0016] 1. The heat generated by the annular electric heating tube is evenly conducted through refractory brick one, ensuring uniform temperature distribution within the oven and consistent heating of the naan bread, resulting in stable baking performance. The high-density aluminum silicate insulation cotton has excellent heat preservation properties, reducing heat loss to the outside of the oven and improving the energy efficiency of the equipment. Refractory brick one and refractory brick two not only conduct heat evenly, allowing the naan bread to be heated evenly during baking, but also use their porous structure to absorb excess moisture, helping the naan bread form a crispy outer shell, locking in internal moisture, restoring the traditional baked taste, and accelerating the production efficiency of naan bread.

[0017] 2. The pull-out mechanism creates a drawer-like structure between the baking tray and the oven body. Under the constraint of the limiting rod, the baking tray is pulled forward. At this time, the fixing rod slides in the groove of the limiting seat, and the bearing roller rotates. Due to the presence of the bearing roller, the friction is reduced, making the baking tray easier to pull out. It can also provide auxiliary support for the pulled-out baking tray. The baking tray is easy to put in and take out of the oven body, which facilitates the insertion and removal of naan bread and improves the safety of the operation. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This embodiment provides a technical solution: a drawer-type pancake maker with uniform heating, including a furnace body 1, a heating mechanism 4, and a pull-out mechanism 5 (the furnace body 1 can be made of cold-rolled steel, with a surface treated by high-temperature spraying, possessing oxidation resistance and deformation resistance characteristics), and also includes a controller 3, which is located on the front side of the upper surface of the furnace body 1. The input terminal of the controller 3 is electrically connected to an external power source. A clearance groove 7 is provided on the front side of the baking tray 2, and a limit frame 8 is slidably connected inside the clearance groove 7. A handle 13 is rotatably connected to the right side of the front end of the limit frame 8. The protrusion on the rear side of the outer surface of the handle 13 is engaged with the slot on the upper side of the front side of the baking tray 2. Fixing rings 9 are provided on both the left and right sides of the front side of the oven body 1. The protrusions on both the left and right sides of the upper surface of the limiting frame 8 are inserted into the interior of the adjacent fixing rings 9. Springs 10 (made of 310S stainless steel) are evenly distributed inside the clearance groove 7. The springs 10 are located between the lower surface of the limiting frame 8 and the bottom wall of the clearance groove 7. An observation window 11 is provided on the upper side of the front side of the baking tray 2. The observation window 11 contains... When baking naan bread, the worker turns the handle 13 forward to release the locking limit of the limiting frame 8, and then presses the limiting frame 8 downward until the protrusions on the left and right sides of the upper surface of the limiting frame 8 leave the fixing ring 9. At this time, the small compression spring 10 of the limiting frame 8 releases the fixed state between the baking tray 2 and the oven body 1. Then the naan dough can be placed on the firebrick 6 in the baking tray 2. After that, the baking tray 2 can be reinserted into the oven body 1, the limiting frame 8 can be released, and the spring 10 will be driven by the rebound force. The limiting frame 8 moves upward until the protrusions on the left and right sides of the upper surface of the limiting frame 8 are inserted into the inside of the fixing ring 9, fixing the baking tray 2 inside the oven body 1. Then, the handle 13 is rotated in the opposite direction, causing the protrusion on the rear side of the outer surface of the handle 13 to engage with the slot on the upper side of the front side of the baking tray 2, locking the limiting frame 8 in place. During the baking process of the naan, the staff can observe the coloring and baking status of the naan in real time through the high-temperature resistant tempered glass 12 of the observation window 11 without having to open the door frequently to check, reducing heat loss and making it easier to control the baking progress.

[0026] Heating mechanism 4 includes a mounting groove 41, an electric heating element 42, refractory bricks 43, a cavity 44, and insulation cotton 45. Mounting grooves 41 are provided on both the left and right walls of the furnace body 1, and also on the bottom wall. Each mounting groove 41 contains an electric heating element 42 and refractory bricks 43 (high-alumina refractory bricks can be used). The refractory bricks 43 are positioned closer to the center of the furnace body 1 than the electric heating elements 42. The electric heating elements 42 are arranged in a ring. A cavity 44 is provided on the inner wall of the furnace body 1, positioned further away from the center of the furnace body 1 than the mounting groove 41. The cavity 44 is filled with insulation cotton 45 (high-density aluminosilicate insulation cotton). The input end of the electric heating element 42 is electrically connected to the output end of the controller 3. Through the control of the controller 3, the electric heating tube 42 works. The heat generated by the annular electric heating tube 42 located inside the insulation cotton 45 is evenly conducted through the refractory brick 43, so that the temperature inside the furnace body 1 is evenly distributed. The heat is evenly conducted through the refractory brick 43, and the temperature difference inside the furnace is ≤5℃, ensuring that the naan is heated evenly and the baking effect is stable. Due to the presence of high-density aluminum silicate insulation cotton 45 filled in the cavity 44 between the furnace body 1 and the electric heating tube 42, the insulation performance is excellent, reducing the heat loss to the outside of the furnace body 1 and improving the energy utilization efficiency of the equipment. The refractory brick 43 and refractory brick 6 inside the electric heating tube 42 can not only conduct heat evenly, but also absorb excess moisture with their own porous structure, helping the naan to form a crispy outer shell, locking in internal moisture, and restoring the traditional baking taste.

[0027] Pull-out mechanism 5: Used to slide and limit the baking tray 2 that is slidably connected inside the furnace body 1. The interior of the baking tray 2 is provided with evenly distributed refractory bricks 6 (refractory bricks 6 can be high alumina refractory bricks). The pull-out mechanism 5 includes a limiting rod 51, a limiting seat 52, and a fixing rod 55. Limiting rods 51 are provided on both the left and right sides of the bottom wall of the furnace body 1. A baking tray 2 is slidably connected between the two limiting rods 51. Limiting seats 52 are provided on both the left and right sides of the lower surface of the furnace body 1. The limiting seats 52 are all U-shaped structures with grooves on the lower side. Fixing rods 55 are provided on both the left and right sides of the rear side of the baking tray 2. The fixing rods 55 are slidably connected. Inside the adjacent limiting seat 52, the pull-out mechanism 5 also includes a rotating shaft 53 and a bearing roller 54. The bearing roller 54 is rotatably connected to the inside of the limiting seat 52 through the rotating shaft 53. The lower side of the outer surface of the fixing rod 55 is in contact with the bearing groove of the adjacent bearing roller 54. Then, under the restriction of the limiting rod 51, the baking pan 2 is pulled out forward. At this time, the fixing rod 55 slides in the slot of the limiting seat 52, causing the bearing roller 54 to rotate around the rotating shaft 53. Due to the presence of the bearing roller 54, the friction is reduced, making the baking pan 2 easier to pull out, and it can also provide auxiliary support for the pulled-out baking pan 2.

[0028] The working principle of the drawer-type flatbread maker with uniform heating provided by this utility model is as follows: When baking naan bread, the operator turns the handle 13 forward to release the locking limit of the limit frame 8, and then presses the limit frame 8 downward until the protrusions on the left and right sides of the upper surface of the limit frame 8 leave the fixing ring 9. At this time, the small compression spring 10 of the limit frame 8 releases the fixed state of the baking tray 2 and the oven body 1. Then, under the restriction of the limit rod 51, the baking tray 2 is pulled forward. At this time, the fixing rod 55 slides in the groove of the limit seat 52, causing the bearing roller 54 to... The rotating shaft 53 is driven to rotate. Due to the presence of the bearing roller 54, the friction is reduced, making the removal of the baking tray 2 smoother and providing auxiliary support for the removed baking tray 2. Then, the dough for the naan bread can be placed on the refractory brick 6 inside the baking tray 2. After that, the baking tray 2 can be reinserted into the oven body 1. The limiting frame 8 is released, and the spring 10 moves the limiting frame 8 upward through its rebound force until the protrusions on the left and right sides of the upper surface of the limiting frame 8 are inserted into the interior of the fixing ring 9, fixing the baking tray 2 inside the oven body 1. Then, the handle 13 is rotated in the opposite direction, causing the handle 13 to... The protrusion on the rear side of the outer surface of the baking tray 2 engages with the slot on the upper side of the front side, locking the limiting frame 8 in place. Under the control of the controller 3, the electric heating tube 42 operates. The heat generated by the annular electric heating tube 42, located inside the insulation cotton 45, is evenly conducted through the refractory brick 43, ensuring a uniform temperature distribution within the oven body 1. The heat is evenly conducted through the refractory brick 43, resulting in a temperature difference within the oven ≤5℃, ensuring consistent heating of the naan bread and stable baking results. The presence of high-density aluminum silicate insulation cotton 45 filling the cavity 44 between the oven body 1 and the electric heating tube 42 effectively maintains the temperature. With excellent performance, it reduces heat loss to the outside of the oven body 1 and improves the energy efficiency of the equipment. The refractory bricks 43 and 6 inside the electric heating tube 42 can not only conduct heat evenly, but also absorb excess moisture with their porous structure, helping the naan to form a crispy outer shell, locking in internal moisture and restoring the traditional baking taste. During the baking process, the staff can observe the coloring and baking status of the naan in real time through the high-temperature tempered glass 12 of the observation window 11 without having to open the door frequently, reducing heat loss and making it easier to control the baking progress.

[0029] It is worth noting that the controller 3 disclosed in the above embodiments can be an STM32F103, and the controller 3 controls the operation of the electric heating tube 42 using methods commonly used in the prior art.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
