Description

Technical Field

[0001] This utility model relates to the field of pizza oven technology, and in particular to a rotating structure for a pizza oven with heat dissipation effect. Background Technology

[0002] As we all know, a pizza oven is a kitchen appliance specifically designed for baking pizzas. A pizza oven mainly consists of an oven body, a burner inside the oven, and a pizza stone to hold the pizza. During baking, the burner sprays flames to bake the pizza placed on the pizza stone. However, the position of the burner is fixed, and the angle of the flames is also fixed. Therefore, a rotating structure is needed in the pizza oven to rotate the pizza stone so that the pizza can be baked evenly.

[0003] Currently, existing pizza oven rotating structures include a motor fixedly mounted on the oven, with the motor's shaft extending into the oven and connecting to a tray. Pizza stones are placed inside the tray, and the motor rotates the pizza stones. However, the high temperatures generated during pizza baking transmit these temperatures along the tray and shaft to the motor. Exposed to high temperatures, the motor's lifespan is shortened, and since the motor is the core component of the rotating pizza oven, this indirectly affects the oven's overall lifespan. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pizza oven rotating structure with heat dissipation effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotating structure for a pizza oven with heat dissipation includes a pizza oven body and a heat dissipation block. The pizza oven body has a baking chamber and an installation cavity separated from the baking chamber. The installation cavity is located at the bottom of the pizza oven body. A motor is fixedly installed in the installation cavity. The rotating head of the motor is connected to a shaft through a coupling. The top end of the shaft is placed in the baking chamber and connected to a tray for holding pizza stones. The middle part of the shaft is connected to the heat dissipation block through a bearing.

[0007] Preferably, the bottom of the heat sink is connected to the motor housing via at least one pair of symmetrical connecting plates.

[0008] Preferably, the connecting piece is C-shaped.

[0009] Preferably, a horizontal plate is provided inside the mounting cavity, and the horizontal plate is provided with a clearance hole at the shaft. The bottom of the motor is suspended, and the heat sink is fixedly installed on the horizontal plate by fasteners.

[0010] Preferably, the tray includes a disc surface and an extension rod fixed around the disc surface. The end of the extension rod is suspended and bent upward to form a limiting edge. A sleeve is provided at the bottom of the disc surface. At least two mutually symmetrical limiting notches are provided at the opening of the sleeve. A transverse locking pin is provided at the top of the shaft rod that can be inserted into the limiting notch.

[0011] By adopting the above solution, this utility model selects to add a heat dissipation block in the middle of the shaft, so that the heat transferred from the tray can be transferred to the heat dissipation block for heat dissipation, thereby effectively reducing the heat transferred from the shaft and extending the service life of the motor; at the same time, by placing the heat dissipation block in the middle of the shaft, a support position is added to the middle of the shaft, which plays a supporting and stabilizing role for the rotation of the shaft and improves rotational stability.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection.

[0019] like Figures 1 to 4 As shown, this embodiment provides a pizza oven rotating structure with heat dissipation effect, including a pizza oven body 1 and a heat dissipation block 2. The pizza oven body 1 is provided with a baking chamber 3 and an installation cavity 4 that is separated from the baking chamber 3. The installation cavity 4 is located at the bottom of the pizza oven body 1. A motor 5 is fixedly installed in the installation cavity 4. The rotating head of the motor 5 is connected to a shaft 7 through a coupling 6. The top end of the shaft 7 is placed in the baking chamber 3 and connected to a tray 9 for holding pizza stones 100. The middle part of the shaft 7 is connected to the heat dissipation block 2 through a bearing 8.

[0020] In this embodiment, a heat sink 2 is added to the middle of the shaft 7. There is contact between the heat sink 2 and the shaft 7, so that the heat transferred from the tray 9 can be transferred to the heat sink 2 for heat dissipation. The heat sink 2 relies on its own thermal conductivity and heat dissipation characteristics and has multiple fins on its surface. The heat dissipation speed is fast, which can effectively reduce the heat transferred from the shaft 7 and extend the service life of the motor 5.

[0021] Meanwhile, because the shaft 7 extends into the baking cavity 3, it will stand vertically at a certain height. However, if the span is too long, it is easy to wobble, making the rotation unstable. In this embodiment, the heat sink 2 not only serves to dissipate heat, but also relies on the fact that the heat sink 2 is placed in the middle of the shaft 7 and connected by the bearing 8 to add a support position to the middle of the shaft 7, which plays a supporting and stabilizing role for the rotation of the shaft 7 and improves the rotation stability.

[0022] Furthermore, for the stable installation of the heat sink 2, in this embodiment, the bottom of the heat sink 2 is connected to the housing of the motor 5 through at least a pair of symmetrical connecting pieces 10, thus forming a connection between the heat sink 2 and the motor 5. The connecting pieces 10 are "C"-shaped, which improves the buffering performance of the connecting pieces 10. A horizontal plate 11 is provided in the mounting cavity 4. The horizontal plate 11 is provided with a clearance hole at the shaft 7. The bottom of the motor 5 is suspended. The heat sink 2 is fixedly installed on the horizontal plate 11 by fasteners (screws or bolts). This not only secures the installation of the motor 5 and the heat sink 2, but also provides appropriate buffering for the vibration generated when the motor 5 is driven, relying on the suspension of the motor 5 and the design of the connecting pieces 10.

[0023] Furthermore, regarding the design of the tray 9, this embodiment preferably adopts a replaceable connection structure. Specifically, the tray 9 in this embodiment includes a circular surface 91 and extension rods 92 fixed around the circular surface 91. The ends of the extension rods 92 are suspended and bent upwards to form limiting edges 93. A sleeve 94 is provided at the bottom of the circular surface 91, and at least two symmetrical limiting notches 95 are provided at the opening of the sleeve 94. A transverse locking pin 71, which can be inserted into the limiting notch 95, is provided at the top of the shaft 7. During assembly, the sleeve 94 is simply fitted onto the top of the shaft 7, and both ends of the locking pin 71 are placed in the limiting notches 95, thus easily completing the assembly. When it is necessary to replace or remove the tray 9, it can be done simply by picking up the tray 9. Because there is no locking structure, no external tools are needed, and assembly and removal are very convenient.

[0024] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
