Description

Technical Field

[0001] The utility model belongs to the technical field of pizza machines, and in particular relates to a pizza machine equipped with high-efficiency refractive double heating. Background Art

[0002] Most pizza machines on the market currently heat food through dual heating tubes (upper heating tube and lower heating tube). The upper heating tube heats the air first and then the hot air heats the food, but this heating method causes heat loss and low heating efficiency. The lower heating tube heats the pizza stone first, and then puts the pizza in when the temperature of the pizza stone reaches 300°C. However, when the temperature of the pizza stone reaches the required temperature of the food, the temperature of the accessories around the cooking chamber also gradually rises, which makes the temperature rise of the whole machine too high, causing the pizza machine to increase heat dissipation, which in turn leads to increased costs. At the same time, the time to bake food is also increased, and the waiting time is long, which affects the user experience. Utility Model Content

[0003] The utility model provides a pizza machine equipped with high-efficiency refractive double heating, aiming to solve the problem that the heating method of the pizza machine in the prior art leads to low heating efficiency and high heat dissipation cost.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] The utility model provides a pizza machine equipped with high-efficiency refractive double heating, comprising:

[0006] A cooking cavity, with a through hole at the bottom;

[0007] A carbon light and heat pipe is located above the cooking cavity; a reflective plate is provided above the carbon light and heat pipe for reflecting the heat of the carbon light and heat pipe downward;

[0008] a storage assembly, located at the bottom of the cooking cavity; and

[0009] The IH coil disk is located below the cooking cavity; the IH coil disk directly heats the storage component through the through hole.

[0010] A further solution: the carbon solar heat pipe is in an unclosed circle; both ends of the carbon solar heat pipe are connected with electrodes.

[0011] Based on the above solution, the carbon light heat pipe is an unclosed circle to ensure that the heat generated by the carbon light heat pipe can be evenly transmitted to the food, thereby ensuring that the food is heated evenly. In addition, the carbon light heat pipe is powered by the electrode so that the carbon light heat pipe can operate normally.

[0012] A further solution: the reflector is in a circular ring shape, and the cross section of the reflector is in an upward convex arc shape.

[0013] Based on the above scheme, the cross-section of the carbon solar heat tube is circular. Therefore, the cross-section of the reflecting plate in this scheme is an upward convex arc, so that the reflecting plate can fully cover the carbon solar heat tube to ensure that the upwardly propagating heat of the carbon solar heat tube is reflected and propagated downward under the action of the reflecting plate.

[0014] Further solution: A pizza machine equipped with high-efficiency refractive dual heating, also includes an inner pot surrounded by a top plate, a bottom plate and side plates, the cooking cavity is arranged inside the inner pot; the reflective plate is located in the inner pot and arranged below the top plate; the IH coil disk is located outside the inner pot and arranged below the bottom plate.

[0015] A further solution: a protective net is provided in the inner pot and below the carbon light heat pipe; a fixing frame is provided on the protective net, and the carbon light heat pipe is fixed in the cooking cavity through the fixing frame.

[0016] Based on the above solution, the protective net plays a protective role for the carbon solar heat pipe to prevent the carbon solar heat pipe from being damaged due to accidental touch.

[0017] A further solution: a heat insulation cover is provided between the top plate and the reflector plate; the reflector plate is fixedly connected to the heat insulation cover.

[0018] Based on the above solution, the heat insulation cover plays a certain role in heat insulation, preventing the heat generated by the carbon light heat tube and the heat in the cooking cavity from being dissipated through the top plate, causing the temperature of the pizza machine shell to rise too high.

[0019] A further solution: the storage assembly includes a storage tray and a microcrystalline board; the through hole is provided in the middle of the bottom plate, and the microcrystalline board is arranged in the through hole; the storage tray is detachably located above the microcrystalline board.

[0020] Based on the above scheme, the structure in which the microcrystalline board is arranged in the through hole in this scheme can be understood as embedding the microcrystalline board on the base plate. On the one hand, the IH coil disk directly heats the microcrystalline board without the base plate, and on the other hand, the placement plate is directly placed on the microcrystalline board, also without the base plate, so that the heat conduction of the microcrystalline board is maximized.

[0021] A further solution: a step is provided at the edge of the through hole, and the microcrystalline plate is arranged on the bottom plate via the step.

[0022] Based on the above solution, the structure of the step is relatively simple and the manufacturing process is simple.

[0023] A further solution: A pizza machine equipped with high-efficiency refractive dual heating also includes an outer shell, and the inner pot is arranged in the outer shell; a bracket is provided at the bottom of the outer shell, and the IH coil disk is arranged directly below the microcrystalline plate through the bracket.

[0024] Based on the above solution, the bracket enables the IH coil disk to be firmly fixed under the microcrystalline board, so that the microcrystalline board can be directly heated.

[0025] A further solution is that a cooling fan is provided at the bottom of the housing and below the IH coil disk.

[0026] Based on the above scheme, since the heat generated by the IH coil disk will be dissipated to cause the temperature of the shell to rise, this scheme designs the cooling fan to dissipate heat and regulate the temperature inside the shell to avoid the temperature of the shell being too high.

[0027] The beneficial effects of the utility model are:

[0028] The utility model provides two heating structures, namely a carbon light heat pipe located above the cooking cavity and an IH coil disk located below the cooking cavity, which heat the food from top to bottom at the same time, so that both the upper and lower parts of the food can be heated and cooked, thereby improving the heating efficiency.

[0029] The light from the carbon light heat pipe irradiates the food and directly heats the food. The reflective plate located above the carbon light heat pipe reflects the heat generated by the side of the carbon light heat pipe away from the food to the food, which not only improves the heating efficiency, but also avoids the problem of the heat generated by the carbon light heat pipe being transmitted to the outside of the cooking cavity, causing the temperature outside the cooking cavity to rise too high, thereby reducing the cost of heat dissipation.

[0030] The IH coil disk directly heats the storage assembly through the through hole, so that the storage assembly is quickly heated up to reach the required temperature point for baking food, thereby heating the lower part of the food on the storage assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Specifically, the top plate 11 and the heat insulation cover 6 may be fixed below the top plate 11 by riveting their edges to each other.
