Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

In the process of flour cake cooking, the coloring stage is positioned at the last stage of flour cake cooking, and in the process of making flour cake, in order to make the temperature of flour cake reach the temperature for generating Maillard reaction (the temperature interval for fully carrying out Maillard reaction is 140-170 ℃), the temperature of flour cake needs to be raised by heat radiation of a heating pipe to a baking tray. The temperature of the dough cake is increased, but the power of the heating pipe is difficult to be greatly increased due to the consideration of safety and the limitation of mains voltage. Secondly, the temperature of the dough cake is raised by increasing the length of the heating pipe. In the scheme of increasing the length of the heating pipe to raise the temperature of the tortilla, if the heating pipe is only assembled near the first pan 202 or the second pan 302, the length of the heating pipe matched with the area of the first pan 202 or the second pan 302 has a certain limitation because the area of the first pan 202 or the second pan 302 is limited. And when the heating pipe is arranged on only one side, the baking tray on the other side can only heat up through the heat emitted by the heating pipe, the heating speed is low, the temperature is lower, and a user can uniformly heat two sides of the flour cake only through the continuous turnover flour cake in the process of making the flour cake, so that the cooking effect is achieved. Therefore, the time for making the dough cake can be influenced, a user needs to judge whether the dough cake reaches the turnover degree according to experience, and if the user cooks for a short time, dough is soft together because the hardness of the dough cake is insufficient; if the user cooks for a longer period of time to turn over, the more caloric side of the tortilla will be burned, while the less caloric side of the tortilla will remain as dough and will not be eaten.

And more importantly, when a user turns over the pancake by opening the pancake baking machine 100, most of heat in the cooking cavity 600 formed by surrounding of each baking tray can be dissipated due to the fact that the pancake baking machine 100 is opened, when only a single heating pipe is arranged, the heating pipe provides less heat for the interior of the cooking cavity 600, the pancake baking machine 100 is frequently opened in the cooking process, and meanwhile, the single heating pipe loses heat, in the process of heating the pancake, the temperature of Maillard reaction is difficult to reach due to insufficient heat transferred to the pancake, or longer cooking is needed to reach the temperature, so that the coloring degree of the pancake is poor, even the whole pancake is not colored, and appetite of the user is reduced; when a plurality of heating pipes are arranged to heat two sides of the pancake simultaneously, the frying and baking machine 100 is frequently opened, so that heat is not only lost, but also the pancake is only heated on one side by the frying and baking machine 100 in the process of opening the frying and baking machine 100, and the service efficiency of the frying and baking machine 100 is affected.

In the technical solution of heating the upper and lower surfaces of the pancake, the first heating tube 400 disposed on the first baking pan 202 and the second heating tube 500 disposed on the second baking pan 302 are generally symmetrically disposed in the prior art, so as to increase the heat of the pancake. Although the symmetrically arranged first heating pipe 400 and second heating pipe 500 can radiate more heat to the dough cake, so that the dough cake can be quickly hardened, the heat of the first heating pipe 400 and the second heating pipe 500 is concentrated, so that good coloring of the area where the dough cake contacts each heating pipe can be generated, and good coloring effect cannot be achieved without the area where the dough cake contacts each heating pipe, namely uniform coloring effect cannot be achieved on the dough cake; it may even occur that the tortilla becomes hard by heating where it contacts each heating tube, while the dough still remains in place where it does not contact each heating tube.

In order to improve the utilization rate of each heating pipe, reduce the frequency of uncapping the frying and baking machine 100 in the cooking process, and can make the cake have more uniform color when coloring, a frying and baking machine 100 of the present application comprises a first cover body 200 and a second cover body 300 which are mutually covered, wherein the first cover body 200 comprises a first baking pan 202 with a first cooking cavity 201, a first heating pipe 400 for providing heat for the first baking pan 202, and the heat of the first baking pan 202 radiates to the first cooking cavity 201; the second cover 300 includes a second grill pan 302 having a second cooking cavity 301, a second heating pipe 500 for supplying heat to the second grill pan 302, and the heat of the second grill pan 302 is radiated to the second cooking cavity 301; a first heating tube 400 including a first inner annular section 401 and a first outer annular section 402 disposed around the center of the first bakeware 202, a second heating tube 500 at least partially overlapping the inner side of the first inner annular section 401, the second heating tube 500 for temperature compensating the inner side of the first inner annular section 401; the projections of the first heating tube 400 and the second heating tube 500 fall onto a horizontal plane, and in the covered state, the first cooking cavity 201 and the second cooking cavity 301 surround to form a cooking cavity 600 for placing food; the first heating tube 400 and the second heating tube 500 heat food placed in the cooking cavity 600 together.

In this embodiment, the first heating pipe 400 and the second heating pipe 500 are spatially arranged to heat the pancake, so that when the pancake is cooked, the heat of the first heating pipe 400 radiates to the first cooking cavity 201 through the first baking pan 202 and is emitted to the second cooking cavity 301 and the second baking pan 302; the heat of the second heating pipe 500 is radiated to the second cooking chamber 301 through the second bakeware 302 while being radiated to the first cooking chamber 201 and the first bakeware 202; so that the heat of the first heating pipe 400 and the heat of the second heating pipe 500 can be rapidly radiated into the entire cooking cavity 600. Under the state of covering, the temperature in the cooking cavity 600 can be quickly increased, the flour cake is hardened to achieve the baking effect, and therefore the flour cake can be cooked without turning over, the cover body of the frying and baking machine 100 can be not opened in the whole cooking process, heat loss is reduced, and the service efficiency of each heating pipe is improved.

The first cooking cavity 201 is formed by a first side wall of the first baking tray 202, and the first side wall extends along the axial direction of the frying and baking machine 100 towards the direction of the second baking tray 302; the second cooking cavity 301 is formed by a second side wall of the second pan 302, which is formed to extend in the axial direction of the fry roaster 100 in the direction of the first pan 202. The length of the first side wall is greater than or equal to the length of the second side wall. The length of the first side wall is usually 5-35 mm, and the length of the second side wall is 2-8 mm.

In order to uniformly heat one side of the tortilla, the first heating pipe 400 is provided as a first inner ring section 401 and a first outer ring section 402 which are provided around the center of the first pan 202. The first outer annular section 402 extends along the extending direction of the dough cake to form an approximate annular structure, and is mainly used for heating the outer side of the dough cake, so that the outer side of the dough cake can be shaped and cured; the first inner annular section 401 is primarily used to heat the inside of the tortilla, thereby allowing the inside of the tortilla to be shaped and cured. The first heating pipes 400 are arranged at different positions of the dough cake, so that the length of the first heating pipes 400 can be prolonged, the heat radiation of the first heating pipes 400 to the first baking tray 202 is increased, all parts of the dough cake can be heated uniformly, and all parts of the dough cake can be cured and colored simultaneously. The double annular arrangement of the first heating tube 400 can make the dough cake better achieve the shaping effect and accelerate the hardening of the dough.

A horizontal plane is provided in the cooking cavity 600, and in the closed state, the horizontal plane is parallel to the ground, and both the projection of the first heating pipe 400 and the projection of the second heating pipe 500 fall onto the horizontal plane. The first heating tube 400 and the second heating tube 500 radiate heat into the cooking cavity 600 together to complete the three-dimensional space heating of the wafer.

In the process of cooking the dough cake, in order to enable two sides of the dough cake to achieve the shaping and curing effects simultaneously, the two sides can have a better coloring effect, the second heating pipe 500 is at least partially overlapped with the inner side of the first inner annular section 401, and the second heating pipe 500 is used for performing temperature compensation on the inner side of the first inner annular section 401. If only the first heating tube 400 is provided, a low temperature region is formed since there is no heating tube inside the first inner ring section 401 of the first heating tube 400, and the temperature inside the second cooking chamber 301 is low since the first heating tube 400 emits less heat to the second bakeware 302; meanwhile, because the heat radiated to the first baking tray 202 from the low-temperature area is lower, less heat is radiated to the second baking tray 302, and the heat obtained from the area corresponding to the low-temperature area on the other surface of the dough cake is lower, so that better coloring effect is difficult. In order to solve the problem of coloring the other surface of the dough cake, a second heating pipe 500 is provided, and when the dough cake is covered, the projection of the second heating pipe 500 at least partially penetrates into the inner side of the first inner annular section 401, so that the low temperature area is correspondingly temperature-compensated. Thus, not only is the first heating pipe 400 used for radiating heat to the first baking tray 202, but also the second heating pipe 500 used for radiating heat to the second baking tray 302, and meanwhile, the second heating pipe 500 is used for correspondingly compensating the temperature of the low-temperature area formed by the first inner annular section 401, so that the temperature gradient in the cooking cavity 600 is more balanced, the second heating pipe 500 can emit heat to the low-temperature area, so that the dough cake corresponding to the area can obtain enough heat, the whole coloring of the dough cake is more uniform and complete, and the phenomenon of coloring and missing of the dough cake is reduced.

In order to meet different heating requirements of the pancake, the pancake heating machine 100 can adapt to different application situations, and the first heating pipe 400 and the second heating pipe 500 jointly heat food placed in the cooking cavity 600. The first heating tube 400 and the second heating tube 500 heat food placed in the cooking cavity 600 together. When the user wants to quickly cook and color the tortilla, the first heating pipe 400 and the second heating pipe 500 can work simultaneously to heat and cook the tortilla, and the heat emitted by the first heating pipe 400 and the second heating pipe 500 together is the largest. Or when the user wants to eat a harder pancake, the first heating pipe 400 is used to heat one surface of the pancake, at this time, water vapor in the pancake is dissipated from the other surface of the pancake, and then the second heating pipe 500 is used to heat the other surface of the pancake, so that less water vapor in the pancake is generated, and the harder pancake is obtained. Alternatively, the second heating tube 500 may be used to heat one side of the tortilla before the first heating tube 400 is used to heat the other side of the tortilla.

Because the first inner ring is arranged inside the first outer ring, the low temperature area surrounded by the first inner ring is smaller, if the second heating pipe 500 is only arranged at the part extending into the inner side of the first inner ring section 401, the length of the second heating pipe 500 is shorter, the heat radiation to the second baking pan 302 is less, most of the places where the dough cake is contacted with the second baking pan 302 cannot be heated well, the heating temperature is unbalanced, and the coloring of the dough cake is uneven. Thus, the second heating tube 500 comprises a second inner annular section 501 and a second outer annular section 502, the second outer annular section 502 being adjacent or at least partially coincident with the first outer annular section 402. That is, the first outer annular section 402 and the second outer annular section 502 are correspondingly arranged, so that the outer annular sections can jointly act to spatially heat the dough cake, and when the first outer annular section 402 and the second outer annular section 502 which are spatially heated are mutually close to each other, the upper surface and the lower surface of the periphery of the dough cake can have enough heat, the heating requirement of the dough cake can be met, the temperature of the dough cake can be increased to a temperature interval meeting Maillard reaction, and the periphery of the dough cake can be uniformly colored. When the first outer ring segment 402 and the second outer ring segment 502 are adjacent, the distance between the first outer ring segment 402 and the second outer ring segment 502 is not too far, so that large-fire heating of the same area of the dough cake is ensured. The first outer ring section 402 is disposed inside the second outer ring section 502, or the first outer ring section 402 is disposed outside the second outer ring section 502. As a preferred option, the distance from the first outer annular section 402 to the center of the first bakeware 202 is greater than the distance from the second outer annular section 502 to the center of the second bakeware 302.

The first heating pipe 400 may be disposed on the upper tray, and the second heating pipe 500 is disposed on the lower tray; alternatively, the first heating pipe 400 is disposed on the lower tray, and the second heating pipe 500 is disposed on the upper tray. Because the heat emitted by the heating pipes rises upwards and converges towards the center of each baking pan, in order to better utilize the rising heat to heat the dough cake, the power of the lower baking pan is typically set to 900W, the power of the upper baking pan is set to 800W, and as a preferred embodiment, the first heating pipe 400 is arranged on the lower baking pan, and the second heating pipe 500 is arranged on the upper baking pan, so that more heat can be converged into the dough cake.

When the first outer ring section 402 and the second outer ring section 502 are at least partially overlapped, the overlapped first outer ring section 402 and second outer ring section 502 can cure and shape the outer side of the dough cake faster, and the water vapor in the dough cake is not easy to diffuse out, so that the dough cake is made into a wet and soft dough cake.

The heating pipe comprises a high-temperature section with higher temperature and a low-temperature section with lower temperature, the high-temperature section occupies most area of the heating pipe, and the resistance wire in the high-temperature section is tightly wound, so that higher heat can be generated. The low temperature section occupies the heating pipe less area, and low temperature Duan Yiduan is connected with the high temperature section, and the other end is connected with the grafting piece, in order to protect the fusible materials such as silica gel, circuit in the grafting piece, the resistance wire winding of low temperature section is more sparse, and the heat that produces is lower. In order to compensate each other between the first heating tube 400 and the second heating tube 500, thereby balancing the temperature throughout the cooking cavity 600, the first heating tube 400 includes two first cold ends 403 adjacent to each other, and the second heating tube 500 includes two second cold ends 503, wherein one of the second cold ends 503 is adjacent to the first cold end 403, and the other second cold end 503 extends away from the first cold end 403, and the two second cold ends 503 are spaced apart. The two first cold ends 403 of the first heating tube 400 are arranged on a first outer annular section 402, the first outer annular section 402 being of annular construction, the two first cold ends 403 being arranged close to each other but spaced apart, such that a region of lower temperature is formed between the two first cold ends 403. The second cold end 503 needs to be offset from the first cold end 403 to offset the cooler regions formed between the low temperature sections from each other and to complement the cooler regions formed between the high temperature sections. Therefore, the extending direction of one of the second cold ends 503 of the second heating tube 500 is the same as that of the first outer ring tube, and the extension line of the other second cold end 503 of the second heating tube 500 passes through the first outer ring tube, so that the region of lower temperature formed by the two second cold ends 503 of the second heating tube 500 is staggered with the region of lower temperature formed by the two first cold ends 403 of the first heating tube 400. The first cold end 403 is connected to the first hot end 404.

The first inner ring-shaped section 401 is a ring-shaped structure disposed around the center of the first pan 202, and although the heat of the first heating tube 400 is concentrated toward the center of the first pan 202, there is a certain gap between the heat obtained by the concentration and the heat of the peripheral area of the first heating tube 400, which is disadvantageous in balancing the overall temperature in the cooking chamber 600 and uniformly coloring the entire cake, and thus the second heating tube 500 further includes a second hot end 504, and the second hot end 504 passes through the center of the second pan 302. I.e. in case of covering, the projection of the second hot end 504 falls to the central position of the second bakeware 302. The second hot end 504 passes through the center of the second baking tray 302, so that heat of the second hot end 504 dissipates heat around the second baking tray 302, and meanwhile, the second hot end 504 located at the center of the frying and baking machine 100 may be better capable of dissipating heat of the second baking tray 302, so that heat of the second hot end 504 can be uniformly diffused into the whole cooking cavity 600, and a vacant area which is not heated by the first heating section is compensated. The centers of the first bakeware 202 and the second bakeware 302 correspond to each other.

In the process of making a tortilla, a user typically makes the shape of the tortilla to approximate that of a baking pan and places the center of the tortilla near the center of the baking pan. If the first heating pipe 400 or the second heating pipe 500 is disposed at a position deviated from the center of the second pan 302, the positions of the heating pipes and the pancake cannot be mutually corresponding, so that each heating pipe cannot directly heat the pancake, and heat is required to be transferred to a place where the first pan 202 or the second pan 302 contacts the pancake, so that the pancake can be heated, and a certain heat loss is caused. Therefore, the first heating pipe 400 is disposed on the lower cover, the second heating pipe 500 is disposed on the upper cover, the first heating pipe is formed by four heating pipes having different extending directions, and the second heating pipe is formed by three heating pipes having different extending directions. The first heating tube 400 is spaced apart from the edge of the first bakeware 202 by a distance such that the heating tube is positioned closer to the center of the first bakeware 202. When the first heating pipes 400 are uniformly and symmetrically distributed on the first baking tray 202, the heat of the first heating pipes 400 can be uniformly diffused to the first baking tray 202 and the dough cake, so that the dough cake is maximally close to the first heating pipes 400. The four heating pipes with different extending directions form the first heating pipe 400, so that the first heating pipe 400 can be uniformly distributed on the first baking tray 202. The second outer annular section 502 of the second heating tube 500 is similar to the first outer annular section 402 and is disposed annularly about the center of the second bakeware 302, and when the second outer annular section 502 is wrapped around the lower temperature region formed by the two first cold ends 403, it bends toward the center of the first bakeware 202 to compensate the temperature of the center of the first bakeware 202.

The first heating pipe 400 and the second heating pipe 500 are integrally formed, the outer sides of the dough cakes are shaped by heating through the first outer ring-shaped section 402 and the second outer ring-shaped section 502, the dough cakes in the peripheral area around the center of the first baking tray 202 are shaped by heating through the first inner ring-shaped section 401, and the inner sides of the first inner ring-shaped section 401 are compensated by temperature through the second inner ring-shaped section 501 passing through the center of the second baking tray 302. The three-stage heating mode which is matched with each other is formed, so that the flour cakes can be cured and shaped rapidly, the heat in the cooking cavity 600 is increased, meanwhile, the temperatures in the cooking cavity 600 are balanced, and the flour cakes can be colored uniformly.

The coloring of the tortilla works well when there is sufficient heat in the cooking chamber 600 and the temperature in the cooking chamber 600 is relatively uniform. The first heating pipe 400 is disposed on the lower cover, the second heating pipe 500 is disposed on the upper cover, the upper cover and the lower cover are connected through a hinge shaft, and the first heating pipe 400 is divided into four parts and the second heating pipe 500 is divided into three parts by passing through the center of the first baking tray 202 and the longitudinal section parallel to the hinge shaft. Under the splitting of the longitudinal section, the first heating pipe 400 and the second heating pipe 500 are split into a plurality of parts, that is, the first heating pipe 400 and the second heating pipe 500 are formed by connecting a plurality of heating pipes with different extending directions and are dispersed at different positions of each baking tray, and the plurality of heating pipes with different extending directions can provide sufficient heat for the interior of the cooking cavity 600. The divided first heating pipe 400 has a first section, a second section, a third section and a fourth section in this order from left to right, wherein a distance between the first section and the second section is equal to the third section and the fourth section

The first outer annular section 402 and the second outer annular section 502 may be provided in the shape of circular arcs, corrugations, etc. If the heat of the second inner ring segment 501 is too large, it interacts with the first inner ring segment 401, and during cooking, the dough will be burnt at a position close to the center due to high temperature, so the second inner ring segment 501 is arranged in a straight shape; alternatively, the second inner annular segment 501 is provided as a corrugated shape. Since the second heating tube 500 is disposed on the upper tray, the second heating tube 500 needs to overcome its own weight when being covered, and the second heating tube 500 needs to be fixed. The rectilinear second inner annular segment 501 facilitates the provision of a fixing means on the peripheral wall of the heating tube, improving the stability of the second heating tube 500. When the temperature of the linear second inner annular section 501 cannot meet the temperature or the coloring degree of the pancake heating of the frying and baking machine 100, the second inner annular section 501 can be corrugated, and more resistance wires are arranged in the corrugated second inner annular section 501, so that more heat can be generated.

In one embodiment, in order to increase the contact area between the first heating tube 400 and the baking tray as much as possible, the first heating tube 400 is a continuous single tube, and includes two symmetrically arranged first outer annular sections 402, and the first inner annular sections 401 connect the first outer annular sections 402; alternatively, the first outer annular section 402 and the first inner annular section 401 are double tubes arranged at intervals. When the first heating pipe 400 is provided as a continuous single pipe, the overall strength of the first heating pipe 400 may be increased, and the first inner ring segments 401 connecting the respective first outer ring segments 402 may increase the length of the first heating pipe 400, thereby allowing the first heating pipe 400 to emit more heat. When the power of the frying and baking machine 100 is larger, the first heating pipes 400 are double pipes arranged at intervals, and the double pipes arranged at intervals can control the heating area of the first baking pan 202 more accurately, so that the coloring of the dough cake is more regular.

In use, each baking pan of the fry roaster 100 is generally configured as a circle with the center of the tortilla generally coincident with the center of the circle, and the first inner annular section 401 and the first outer annular section 402 are configured as circles with the center of the circle being the center of the first baking pan 202 in order to provide better heating of the tortilla by the first heating tube 400. The first inner annular section 401 and the first outer annular section 402 are provided in a circular shape substantially identical to the shape of the first bakeware 202 and the tortilla, which can reduce the gap area where the tortilla does not overlap the first heating duct 400. Meanwhile, the arrangement of the near-circular shape can also help the first heating tube 400 to uniformly spread the heat around, so as to prevent the situation that the temperature of a certain area on the first baking tray 202 is too high or the temperature of a certain area is too low.

When the cover is covered or the frying and baking machine 100 is moved, the first baking pan 202 is impacted by external force, and if the first heating pipe 400 is a continuous single pipe, the first inner annular section 401 and the first outer annular section 402 are connected through arc heating sections. If the first inner ring segment 401 and the first outer ring segment 402 are connected by the linear heating segment, the connection of the first inner ring segment 401 and the first outer ring segment 402 is easily broken when being impacted by external force. Therefore, the first inner annular section 401 and the first outer annular section 402 are connected through the arc-shaped heating section, so that when external force impact is received, the arc-shaped heating section can play a good role in buffering the impact force, and the first heating pipe 400 is prevented from being broken.

In order for the first heating pipe 400 and the second heating pipe 500 to provide sufficient heat to the cooking chamber 600 to meet the requirement of coloring the tortilla, the first outer ring section 402 includes a first opening 700 and a second opening 701, the first inner ring section 401 includes a third opening 702, both ends of the second opening 701 are integrally connected with both ends of the third opening 702 to form the first heating pipe 400, and both ends of the first opening 700 are used for electrical connection. The first outer annular section 402 is provided with a plurality of openings, and then different annular sections are required to be connected to form the first outer annular section 402, so that the length of the first outer annular section 402 can be increased by different annular sections, and the temperature in the cooking cavity 600 can be more uniform by the annular sections arranged at different positions, so that the coloring effect is improved.

The temperature at each opening is low, if the openings are close to each other, the temperature of the area is reduced, so that the first outer annular section 402 and the first inner annular section 401 are separately arranged, the first outer annular section 402 is arranged around the center of the first baking tray 202, the first openings 700 are formed at two ends, the first inner annular section 401 is arranged around the center of the first baking tray 202, the third openings 702 are formed at two ends, and the first openings 700 and the third openings 702 are arranged in a staggered manner. The arrangement of the first outer annular section 402 and the first inner annular section 401 around the center of the first bakeware 202 can uniformly spread the temperature of the first outer annular section 402 and the first inner annular section 401 throughout the first bakeware 202. The temperature of the first opening 700 and the third opening 702 is lower, and the dislocation arrangement can make the temperature of each hot end compensate, so that the temperature in the cooking cavity 600 can reach the effect of balancing.

In the process of making the tortilla by the baking machine 100, the tortilla can be quickly hardened in the process of making by the coaction between the first outer annular section 402 of the first heating pipe 400 and the second outer annular section 502 of the second heating pipe 500 in space. In addition, one surface of the dough cake can be heated and colored by the first inner annular section 401 of the first heating pipe 400, the other surface of the dough cake can be heated and colored by the second inner annular section 501 of the second heating pipe 500, and meanwhile, the inner side of the first inner annular section 401 is subjected to temperature compensation, so that the whole dough cake can be well heated and colored. And the three-dimensional heating effect of the first heating pipe 400 and the second heating pipe 500 allows the dough cake to be cooked without turning over.

As shown in fig. 7, in order to enable the dough cake to be heated uniformly, the first heating pipe or the second heating pipe compensates for the place where the first heating pipe or the second heating pipe cannot cover. The first heating pipe comprises two first cold ends, the first cold ends form a first opening, the second heating pipe comprises two second cold ends, the two second cold ends form a fourth opening, the first opening and the third opening are arranged in a staggered mode and are respectively positioned on opposite sides of the center of the first baking tray, and the fourth opening is arranged in a staggered mode with the first opening and the third opening respectively; or the first opening and the third opening are positioned on the same side, the second heating pipe comprises a second outer annular section, the two ends of the second outer annular section form a fourth opening, and the fourth opening is respectively staggered with the first opening and the third opening.
