Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and is a triangular electric heating rotating baking plate and baking oven. Background Technology

[0002] With the introduction of Western dietary habits and the increasing diversity and quality requirements of people's lives, more and more bakeries have appeared on the streets. As a result, all kinds of baking equipment have been invented. One of the most commonly used baking equipment on the market is the electric oven. The oven is cubic in shape with preheating tubes on both the top and bottom surfaces. When baking, the dough is placed on a tray and then put into the oven, and the preheating tubes are turned on for baking. Another commonly used baking equipment is the traditional oven used to make naan and flatbread. The oven is generally urn-shaped with a heating device on the bottom surface. When baking, the dough is attached to the inner wall of the container, baked, and then scooped out of the oven.

[0003] When using an electric oven, the dough is placed on a tray, which prevents the baked goods from developing the crispy, hard crust that comes with traditional ovens. Additionally, the oven uses radiant heating from above, which doesn't fully utilize the heat from the upper preheating element. In contrast, in a urn oven, the dough is attached to the side wall, so it cannot be too soft. Otherwise, the dough will sag due to gravity and fall off the side wall, preventing proper baking. Summary of the Invention

[0004] This invention provides a triangular electric heating rotating baking plate and baking oven, which overcomes the shortcomings of the prior art and can effectively solve the problems of low heat utilization and high requirements for dough in existing electric ovens and baking ovens.

After the preheating tube operates and the baking plate temperature rises to a certain value, the prepared dough is placed on the top baking plate. Then, the central shaft is rotated 120 degrees to rotate one of the tilted baking plates to the top and make it horizontal. The prepared dough is then placed on this baking plate. Finally, the central shaft is rotated 120 degrees to rotate the last tilted baking plate to the top and make it horizontal. The prepared dough is then placed on this baking plate. The input terminal... The output terminals can rotate relative to each other, so that the preheating tube can still be connected to the power cord while the central shaft is rotating. The preheating tube can work continuously and continuously heat the baking plate when it is powered on. The heat storage layer can reduce heat loss on the one hand, and can also install the preheating tube and the baking plate together on the other hand. After the baking plate reaches a certain temperature, the dough can be pasted on. After the surface of the dough and the baking plate are bonded together, they will dry and solidify quickly, and the dough and the baking plate will stick tightly together. This way, the baking plate will not fall off when it rotates with the central shaft. After the dough on the top horizontal baking plate rotates once and returns to a horizontal position, it will be baked, achieving the baking effect of a traditional pancake oven. Then the baked pancake can be removed, and the prepared dough can be placed on the top of the baking plate again. This cycle can be repeated to continuously bake pancakes.

Detailed Implementation

[0037] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0038] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0039] The present invention will be further described below with reference to the embodiments and accompanying drawings: Example 1: As shown in the attached document Figures 1 to 4 As shown, the triangular electrically heated rotating baking plate includes a left fixed plate 1, a right fixed plate 2, a baking plate 3, an electric slip ring, and a central shaft 4 arranged in a left-right direction. The left fixed plate 1 and the right fixed plate 2 are fixedly installed on the outer side of the central shaft 4 at intervals. Three baking plates 3 are fixedly installed circumferentially between the right side of the left fixed plate 1 and the left side of the right fixed plate 2. The three baking plates 3, the right side of the left fixed plate 1, the left side of the right baking plate 3, and the outer side of the central shaft 4 form a closed preheating cavity 5. The preheating cavity 5 is provided with heat storage layers 6 corresponding to the baking plates 3. Each heat storage layer 6 is fixed together with the baking plate 3 at the corresponding position. Each heat storage layer 6 is provided with at least one preheating pipe 7 at intervals along the width direction of the baking plate 3. An electric slip ring is installed on the outer side of the right part of the central shaft 4 corresponding to the right position of the right fixed plate 2.

[0040] According to the requirements, three baking plates 3 are fixedly installed circumferentially between the right side of the left fixing plate 1 and the left side of the right fixing plate 2, surrounding the outside of the central axis 4. The included angle between two adjacent baking plates 3 is 60 degrees. The preheating pipe 7 is a known technology, such as an electric heating pipe. The heat storage layer 6 is a known technology, such as high-temperature cement or high-temperature refractory clay. The electric slip ring is a known electric slip ring or collector ring.

[0041] In use, brackets or bearings are installed at both ends of the central shaft 4. The input terminal 8 can be fixed to the brackets or bearings via an insulating frame. Then, the power cord is connected to the input terminal 8. The central shaft 4 is rotated so that one of the baking plates 3 is at the top and horizontal. At this time, the longitudinal cross-section of the other two baking plates 3 forms an upward-opening V-shape. After the preheating pipe 7 works and the temperature of the baking plates 3 rises to a certain value, the prepared dough is placed on the top baking plate 3. Then, the central shaft 4 is rotated 120 degrees to rotate one of the tilted baking plates 3 to the top and make it horizontal. The prepared dough is then placed on the top baking plate 3. Finally, the central shaft 4 is rotated 120 degrees to rotate the last tilted baking plate 3 to the top and make it horizontal. The prepared dough is then placed on the top baking plate 3. The input terminal 8 and the output terminal 9 can rotate relative to each other. In this way, the central shaft 4 rotates... During operation, the preheating tube 7 can still be connected to the power cord and can work continuously. When the preheating tube 7 is powered on, it continuously heats the baking plate 3. The heat storage layer 6 can reduce heat loss. There are fasteners on the back of the baking plate 3 that are welded to fix the preheating tube 7 and the heat storage layer 6. The fasteners are existing known technologies, such as high-temperature resistant steel bars, wire mesh, pipe clamps, or screws. After the baking plate 3 reaches a certain temperature, the dough can be pasted on. After the surface of the dough and the baking plate 3 are quickly dried and cured, the dough and the baking plate 3 will stick tightly together. In this way, the baking plate 3 will not fall off when it rotates with the central axis 4. After the dough on the top horizontal baking plate 3 rotates once and returns to a horizontal state, it will be baked, achieving the baking effect of a traditional pancake oven. Then the baked pancake can be removed, and the prepared dough can be placed on the top of the baking plate 3 again. This cycle can be repeated to continuously bake pancakes.

[0042] While rotating the central shaft 4, dough can be made. When the baking plate 3 is rotated to a horizontal position, the prepared dough can be placed on the upper side of the baking plate 3, which can save space and improve the efficiency of baking. The central shaft 4 can be rotated using existing known technologies, such as a stepper motor, an intermittent 120-degree rotation mechanism, or the 120-degree intermittent rotation precision positioning mechanism disclosed in Chinese patent document CN215033291U.

[0043] You can also install fish grilling clips or fix grilling mesh on the grilling plate 3, so that you can use the grilling plate 3 to grill fish, or meat skewers or vegetable skewers, which can increase its functionality.

[0044] The above-mentioned triangular electrically heated rotating baking plate can be further optimized and / or improved according to actual needs: Example 2: As an optimization of the above examples, as shown in the appendix. Figure 1 , 3 As shown in Figure 4, the baking plate 3 is bent along the radial direction of the central axis 4 on both sides to form a connecting plate 8. Each connecting plate 8 has several through holes spaced apart on the left and right. The connecting plates 8 of each two adjacent baking plates 3 are fixed together by the connectors 9 provided in the through holes.

[0045] According to the requirements, the front and rear sides of the top baking plate 3 are bent along the radial direction of the central axis 4 to form connecting plates 8. In this embodiment, the included angle between the connecting plates 8 on both sides of each baking plate 3 and the baking plate 3 is 150 degrees. The top baking plate 3, the left fixed plate 1, and the right fixed plate 2 can form a trapezoidal baking groove with an upward opening and a wider top and narrower bottom. After the dough is placed on the top side of the baking plate 3, a certain amount of water can be injected. After the baking plate 3 is heated, water vapor can be generated. Thus, a box-shaped cover with an downward opening is placed on the top side of the baking plate 3. Before baking, it can be steamed for a period of time, which is suitable for making some stuffed pasta.

[0046] Each connecting plate 8 has 3 to 10 through holes spaced apart on the left and right sides. The depth of the through holes is the same as the thickness of the connecting plate 8. The connecting parts 9 can be existing known technologies, such as rivets or connecting bolts with nuts screwed on. In this embodiment, the connecting bolts with nuts screwed on the ends are used. The connecting plates 8 on the front side of the upper baking plate 3, the connecting plates 8 on the upper side of the front baking plate 3, the connecting plates 8 on the rear side of the upper baking plate 3, the connecting plates 8 on the upper side of the rear baking plate 3, the connecting plates 8 on the lower side of the front baking plate 3, and the connecting plates 8 on the lower side of the rear baking plate 3 are all fixed together by connecting bolts with nuts screwed on the ends after passing through the through holes. This facilitates the disassembly and assembly of the baking plate 3.

[0047] Example 3: As an optimization of the above examples, as shown in the appendix. Figures 1 to 10As shown, the central shaft 4 has a hollow structure. The slip ring includes a base 20, an isolation plate 21, a fixed electrode plate 10, a rotating electrode plate 11, an electrode ring 12, a carbon brush 13, and a fixed bushing 14. The base 20 and the fixed electrode plate 10 are fitted on the outer side of the central shaft 4 at intervals to the right of the right fixed plate 20. Several isolation plates 21 are fixedly installed at intervals on the right side of the base 20. The left side of the fixed electrode plate 10 is fixedly installed together with the right side of the isolation plate 21. The fixed bushing 14 is fixedly installed on the outer side of the right part of the central shaft 4 at the right of the fixed electrode plate 10. The rotating electrode plate 11 is fixedly installed on the outer side of the fixed bushing 14. The left side of the rotating electrode plate 11 has several left-facing, annular mounting grooves at intervals from the inside to the outside. At least one through hole is evenly distributed along the circumference on the right side of the rotating electrode plate 11 corresponding to each mounting groove. An electrode ring 12 is fixedly installed in each mounting groove. Each of the fixed electrode plates 10 at the position of electrode ring 12 has at least one through-hole on the right side of the circumference. A carbon brush 13 is fixedly installed in each fixed hole. The right side of each carbon brush 13 is in contact with the left end of the corresponding electrode ring 12. At least one first wire hole 18 with internal and external communication is evenly distributed on the outer side of the fixed bushing 14 at the right position of the rotating electrode plate 11. A second wire hole with internal and external communication is provided on the outer side of the right part of the central shaft 4 at each position of the first wire hole 18. At least one third wire hole 19 with internal and external communication is evenly distributed on the outer side of the central shaft 4 at the left position of the right fixed plate 2. A first connecting cable 15 is provided in the central shaft 4. The first end of the first connecting cable 15 passes through the third wire hole 19 and is electrically connected to the preheating tube 7. The second end of the first connecting cable 15 passes through the second wire hole and the first wire hole 18 in sequence and is electrically connected to the corresponding electrode ring 12.

[0048] Depending on the requirements, the chassis 20, isolation plate 21, fixed electrode plate 10, and rotating electrode plate 11 are all made of existing known insulating materials, such as phenolic resin, ceramic, epoxy resin, or polytetrafluoroethylene. The chassis 20, isolation plate 21, and fixed electrode plate 10 can all be U-shaped with the opening facing downwards. The isolation plate 21 is designed to ensure a certain distance between the chassis and the fixed electrode plate 10, so that after the right side of the carbon brush 13 contacts the electrode ring 12, the left side of the carbon brush 13 can be connected to the power cord. Corresponding to each mounting slot position, the rotating electrode plate 11 has two left and right through-holes evenly distributed along the circumference on the right side. The interconnecting holes allow each electrode ring 12 to have two carbon brushes 13 in contact with it for conductivity. This prevents the conductivity from deteriorating due to uneven wear between the electrode ring 12 and the carbon brushes 13, and also extends the service life. The electrode ring 12 is a ring plate made of copper. The right side of the fixed electrode plate 10 corresponding to the position of each electrode ring 12 is provided with a left-right through fixed hole at intervals along the circumference. The positions of the first wire through hole 18 and the second wire through hole are one-to-one. There are 1 to 4 first wire through holes 18 and 4 second wire through holes evenly distributed along the outer side of the central axis 4. The first connecting cable 15 is a known high-temperature resistant connecting cable.

[0049] In use, the chassis 20 can be fixedly installed together with the bracket or shaft seat, and then the power cord is electrically connected to the left side of the carbon brush 13 at the corresponding position. The power cord and the first connecting cable 15 are electrically connected together through the carbon brush 13 and the corresponding electrode ring 12. In this way, when the central shaft 4 rotates, the first connecting cable 15 and the power cord can be prevented from getting tangled together, so that the preheating tube 7 can continue to work normally. Setting the carbon brush 13 and the electrode ring 12 between the fixed electrode plate 10 and the rotating electrode plate 11 can improve safety. The left outer side of the fixed bushing 14 has a connecting flange, which makes it easy to fix and install together with the rotating electrode plate 11.

[0050] Example 4: As an optimization of the above examples, as shown in the appendix. Figure 3 , 4 As shown in Figure 10, a temperature-sensitive switch 16 is fixedly installed on the heat storage layer 6 in the preheating chamber 5. Each heat storage layer 6 has 1 to 3 preheating tubes 7 spaced apart along the width direction of the baking plate 3. A second connecting cable 17 is provided in the central shaft 4. The first end of the second connecting cable 17 passes through the third wire hole 19 and is electrically connected to the temperature-sensitive switch 16. The second end of the first connecting cable 15 passes through the second wire hole and the first wire hole 18 in sequence and is connected to the corresponding electrode ring 12.

[0051] Depending on the requirements, the temperature sensor 16 is a known technology, such as the 17AM temperature switch automatic reset overcurrent protector, and the second connecting cable 17 is a known high-temperature resistant connecting cable.

[0052] In use, connect the temperature sensor 16 to the coil of the intermediate relay, connect the preheating tube 7 to the normally closed contact of the intermediate relay, and connect the input terminal of the intermediate relay to the power supply terminal. When the central shaft 4 is driven to rotate, the preheating tube 7 can continue to work normally. When the temperature reaches a certain value, the temperature sensor 16 causes the normally closed contact of the intermediate relay to open, so that the preheating tube 7 stops working after power is cut off. When the temperature drops, the normally closed contact of the intermediate relay closes, and the preheating tube 7 continues to work after being powered on. This can prevent the temperature of the baking plate 3 from getting too high and ensure the quality and taste of the baked goods.

[0053] Example 5: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2 As shown in Figures 4 and 10, the system also includes a controller. A left support body 23 is rotatably mounted on the outer left side of the central shaft 4, corresponding to the left side of the left fixed plate 1. A right support body 24 is rotatably mounted on the outer right side of the central shaft 4, which is fixed on the left side of the chassis 20. A base 25 is fixedly mounted on the lower right side of the right support body 24. A drive motor 26 is fixedly mounted on the upper side of the base 25. The right end of the output shaft of the drive motor 26 is connected to the right end of the central shaft 4. The controller is electrically connected to the drive motor 26 and the carbon brush 13 at the corresponding position.

[0054] Depending on the requirements, the controller uses existing known technology, such as the OHR-DN10 rail-mounted digital display controller. The drive motor 26 is a known stepper motor. The right end of the stepper motor's output shaft is connected to the right end of the central shaft 4 via a sprocket and chain drive. The left support 23 and the right support 24 can be known brackets or shaft seats, which facilitates the installation of the central shaft 4. Each time the drive motor 26 works, it drives the central shaft 4 to rotate 120 degrees, corresponding to the three baking plates 3. Thus, each rotation of the central shaft 4 by the drive motor 26 will cause one of the baking plates 3 to be at the top and in a horizontal position, which facilitates the placement of dough and the removal of baked goods, reducing labor intensity. The electric slip ring, base 25, and drive motor 26 can also be set on the left side. Based on the placement of the triangular electric heating rotating baking plate 3, which is convenient for the repair of this part or the operator's hand habits, the electric slip ring, base 25, and drive motor 26 can be set on the left or right side.

[0055] Example 6: As an optimization of the above examples, as shown in the appendix Figure 1 , 2 As shown in Figures 4 and 10, a time relay is also included. A limit switch 27 is installed on the upper right side of the right support body 24. A sensing arm 22 corresponding to the three baking plates 3 is fixedly installed on the outer right side of the center shaft 4, which is located on the right side of the fixed shaft sleeve 14. Both the limit switch 27 and the time relay are electrically connected to the controller.

[0056] Depending on the requirements, the sensing arm 22 can be formed by three identical sensing plates evenly spaced and fixed on the outside of the annular connecting plate. The inside of the connecting plate is fixedly installed with the outside of the central shaft 4. The included angle between the three sensing plates is 120 degrees. The sides of the three sensing plates away from the center are arc-shaped. The sensing arm 22 can also be triangular. The center of the sensing arm 22 is provided with a shaft hole for mounting the central shaft 4. Each corner of the sensing arm 22 is provided with a rounded chamfer. The time relay and the limit switch 27 are both existing known technologies.

[0057] In use, when one end of the sensing plate of the sensing arm 22 rotates to abut the contact end of the limit switch 27, the drive motor 26 stops rotating and the time relay starts timing. At this time, one of the baking plates 3 is at the top and in a horizontal position, and dough can be placed or baked. After the set time is reached, the output shaft of the drive motor 26 starts rotating, and the drive motor 26 drives the central shaft 4 to rotate, so that the other end of the sensing plate rotates 120 degrees and abuts the contact end of the limit switch 27. The output shaft of the drive motor 26 stops rotating, and the time relay starts timing. In this way, the other baking plate 3 is at the top and in a horizontal position, so dough can continue to be placed or baked. This process can be repeated to place dough or take out baked. This improves efficiency and ensures the quality and taste of the baked.

[0058] Example 7: As attached Figures 11 to 18 As shown, the baking oven includes a triangular electrically heated rotating baking plate, a box body 28, and a box cover 29. The upper inner side of the box body 28 has an upward-opening baking chamber 30. The left fixing plate 1 and the right fixing plate 2 are both located inside the baking chamber 30. The right side of the box body 28 has a through-hole. The inner left side of the box body 28 corresponding to the right mounting hole has a left mounting hole opening to the right. The left side of the left support body 23 is fixed to the inner left side of the box body 28. The left end of the central shaft 4 is rotatably installed in the left mounting hole. The left side of the right support body 24 is fixed to the right side of the box body 28. The outer right side of the central shaft 4 is rotatably installed in the right mounting hole. The upper rear side of the box body 28 is hinged to the rear side of the box cover 29. The inner front and inner rear sides of the baking chamber 30 corresponding to the position below the left fixing plate 1 are provided with heating tubes 31.

[0059] Depending on the requirements, both the left support 23 and the right support 24 are plate-shaped structures, and both the left support 23 and the right support 24 are integrally set with the box body 28. The left support 23 and the right support 24 can also be the left side wall and the right side wall of the box body 28. The box cover 29 and the box body 28 can be hinged together by existing known hinges, such as damping hinges or hydraulic support rods.

[0060] The baking oven of this application has a grooved triangular combined baking plate installed in a rectangular box 28. Dough can be pasted on the surface of the baking plate 3. A heating tube 31 is installed at the bottom of the baking chamber 30 to bake the dough from the side and upward of the grooved triangular combined baking plate, so as to achieve the baking effect of the dough.

[0061] The baking oven body 28 of this application has a rotatable grooved triangular combination baking plate in the upper middle part. The drive motor 26 drives the central shaft 4 to rotate, and the combination baking plate rotates. When the baking plate 3 with dough attached rotates to the lower baking chamber 30, the heating tube 31 in the lower part works to bake the dough until it is cooked. The heat storage layer 6 covering the back of the combination baking plate 3 can maintain the temperature of the baking plate 3 for a certain period of time. When the oven lid 29 is opened, the surface temperature of the baking plate 3 can be maintained to ensure the temperature required for attaching the dough, so that the baking achieves the expected effect.

[0062] The baking oven of this application has a preheating tube 7 installed on the back of each baking plate 3 of the slotted triangular combination baking plate. This allows the baking plate 3 to be heated directly without relying on the heating tube 31 of the baking chamber 30. This prevents the baking plate 3 from losing temperature during continuous baking of pastries, thus avoiding the phenomenon that the bottom of the dough is not fully cooked or turns white. Heating tubes 31 are set on both sides of the baking chamber 30 for symmetrical heating. The dough is positioned in the front and rear of the baking chamber 30, making the positions mirror symmetrical. The upper and lower parts of the dough are reversed, which makes the dough heat more evenly.

[0063] The above-mentioned baking oven can be further optimized and / or improved according to actual needs: Example 8: As an optimization of the above examples, as shown in the appendix Figure 12 , 13 As shown in Figures 14, 15, and 16, an annular baffle 32 is fixedly installed on the inner side of the upper part of the box 28. There is a gap between the inner left side of the baffle 32 and the upper left side of the left fixed plate 1, and a gap between the inner right side of the baffle 32 and the upper right side of the right fixed plate 2. There are gaps between the inner front and inner rear sides of the baffle 32 and the connecting plates 8 on both sides of the baking plate 3 which is rotated to the top and is in a horizontal state. Four moving wheels 35 are installed circumferentially on the lower side of the box 28. A storage slot with an opening facing forward is provided on the front side of the lower part of the box 28 corresponding to the position below the baking chamber 30. A storage channel 33 is provided between the upper rear side of the storage slot and the lower part of the baking chamber 30. A storage box 34 is provided in the storage slot.

[0064] Depending on the requirements, the caster 35 is a known technology, such as a heavy-duty omnidirectional brake caster. The storage slot can have one or two storage boxes 34. The storage box 34 can be used to store the prepared pancakes. The baffle 32 can reduce the heat loss of the lower part of the baking chamber 30, thereby saving the baking time of the pancakes. There is a gap between the inner front side of the baffle 32 and the connecting plate 8 on the front side of the baking plate 3 when it is rotated to the top and in a horizontal state. There is also a gap between the inner rear side of the baffle 32 and the connecting plate 8 on the rear side of the baking plate 3 when it is rotated to the top and in a horizontal state.

[0065] Example 9: As an optimization of the above examples, as shown in the appendix Figure 12 , 13 As shown, the inner wall of the front part of the baking chamber 30, which is located below the left fixed plate 1, has a forward inclined surface 36 with the upper part tilted forward relative to the lower part, and the inner wall of the rear part of the baking chamber 30 has a rear inclined surface 37 that is symmetrically arranged with the forward inclined surface 36. A lower fixed frame 38 is fixedly installed on both the forward inclined surface 36 and the rear inclined surface 37, and a heating tube 31 is fixedly installed on the lower fixed frame 38.

[0066] As required, the heating tube 31 is U-shaped with its opening to the right. During use, the front inclined surface 36 is parallel to the V-shaped front baking plate 3, and the rear inclined surface 37 is parallel to the V-shaped rear baking plate 3. In this way, the heat emitted by the heating tube 31 when it is powered on can heat the dough on the baking plates 3 on both sides of the lower part of the baking chamber 30. The baking method of the baking oven of this application is to heat and bake from the lower angle. It can not only bake the dough in a radiant manner, but also allow the heated air to circulate upward to bake the dough. This can make full use of the efficiency of the heating tube 31 and improve the thermal efficiency of the heating tube 31.

[0067] Example 10: As an optimization of the above embodiments, as shown in the appendix Figure 11 , 12 As shown in Figures 13 and 16, a sealing step is provided on the inner side of the upper end of the baking chamber 30, and a sealing strip 39 is fixedly installed on the sealing step. An upper fixing frame 40 is fixedly installed on the lower side of the box cover 29, and 2 to 5 electric heating tubes 41 are fixedly installed on the upper fixing frame 40 at intervals. 2 to 4 through holes are provided on the left and right sides of the upper rear side of the box body 28 corresponding to the position below the sealing strip 39, and an air injection pipe 42 with its front end located below the sealing strip 39 is sealed and fixedly installed in each through hole.

[0068] According to the requirements, each heating element 41 is connected to the controller. The long side of each baking plate 3 is bent to form a connecting plate 8. The angle between the connecting plates 8 on both sides and the baking plate 3 is 150 degrees. The uppermost baking plate 3, the left fixed plate 1, and the right fixed plate 2 can form a trapezoidal baking groove with an upward opening and a wider top and narrower bottom. When the baking plate 3 is horizontal with one side facing upward, it can store a certain amount of water, which is convenient for steaming the dough in the early stage of baking to achieve the baking effect. It can also be steamed for a period of time before baking, which is suitable for making some filled pasta (such as baked buns). A control valve is installed at the rear of the gas injection pipe 42. The rear end of the gas injection pipe 42 can be connected to the gas outlet of the existing known steam generator, so that some filled pasta can be steamed.

[0069] Example 11: As an optimization of the above embodiments, as shown in the appendix. Figures 11 to 17 As shown, the upper side of the box 28 is provided with an observation hole that runs through the top and bottom. An observation window 43 is sealed and fixedly installed inside the observation hole. Both the inner side of the box 28 and the inner side of the box cover 29 are provided with closed insulation cavities, which are filled with insulation layer 44.

[0070] According to the requirements, the upper side of the box 28 is provided with two elongated oval observation holes that run vertically through each other. The observation window 43 is made of existing high-temperature resistant glass, such as fireproof glass. L-shaped baffles are installed on the upper and lower sides of the observation window 43. The baffles are fixedly installed in the observation holes. The box 28 and the box cover 29 are both made of an inner shell and an outer shell. A closed heat insulation cavity is formed between the outer side of the inner shell and the inner side of the outer shell. The heat insulation cavity is filled with a heat insulation layer 44. The heat insulation layer 44 can be a known technology, such as heat insulation cotton or STP heat insulation board. A known latch is provided between the front side of the box cover 29 and the upper front side of the box 28.

[0071] Example 12: As an optimization of the above embodiments, as shown in the appendix Figure 12 , 14 As shown in Figures 17 and 18, a measuring hole is provided on the lower right side of the box 28, which runs through the left and right sides. A thermometer 45 is installed in the measuring hole, with its left end located on the inner right side of the baking chamber 30. The thermometer 45 and the heating tube 31 are both electrically connected to the controller.

[0072] Depending on the requirements, the temperature measuring instrument 45 uses existing known technology, such as a temperature sensor (K type or Pt100 type), which can monitor the temperature inside the baking chamber 30, avoid the heating tube 31 inside the baking chamber 30 from getting too hot during the working time, ensure the baking quality of the pancakes, and save energy. The lower right side of the box body 28 is provided with a through hole for wiring, and the wiring hole is provided with a connecting cable for connecting the heating tube 31 and the controller.

[0073] When in use, the controller is powered on, and the preheating tube 7 and the heating tube 31 are powered on to start heating. When the set temperature is reached, the temperature sensor switch 16 stops the preheating tube 7 through the controller, and the heat storage layer 6 maintains the temperature to prevent the baking plate 3 from losing temperature too quickly.

[0074] Open the lid 29, stick the dough onto one of the upward-facing baking plates 3, close the lid 29, and the drive motor 26 is powered on to enter the timed baking mode. At this time, the dough that was just placed in rests in the upper part of the baking chamber 30. When the set resting time ends, the drive motor 26 drives the central shaft 4 to rotate and causes the baking plate 3 to rotate 120 degrees. At this time, the rounded chamfer of the moving ring 14 just presses the contact end of the limit switch 27, the drive motor 26 stops rotating, and the time relay starts timing. The dough enters the lower part of the baking chamber 30.

[0075] The dough first enters the rear of the baking chamber 30 and bakes there for a period of time. After the timer finishes, the drive motor 26 rotates the baking plate 3 120 degrees and enters the front of the baking chamber 30. At this time, the dough is mirror-symmetrical to the previous baking position, and the upper and lower parts of the dough will be reversed, which makes the dough bake more evenly.

[0076] After a period of static baking, once the set time is reached, the baking plate 3 rotates 120 degrees, and the dough returns to its initial state, that is, the dough faces upward. At this point, one stage of baking process has been completed. If it has not reached the desired doneness, it can be rotated for another cycle until the dough is baked to perfection.

[0077] The above technical features constitute various embodiments of this utility model, which have strong adaptability and optimal implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
