Description

Technical Field

[0001] The utility model relates to the technical field of pizza ovens, in particular to a pizza oven with high efficiency and synchronous heat dissipation. Background Art

[0002] In pizza oven design, heat dissipation has always been a key factor affecting equipment performance and safety. Traditional pizza ovens typically use a single fan for heat dissipation, installing a fan inside the casing or cavity to expel hot air. However, this design often suffers from the following issues:

[0003] 1. Low heat dissipation efficiency: A single fan is difficult to effectively cover the heat source area of the entire equipment, resulting in heat accumulation in some areas and uneven heat dissipation, which cannot meet the needs of high-temperature cooking equipment.

[0004] 2. Increased equipment temperature: Due to uneven heat dissipation, key components such as circuit boards and door assemblies are prone to overheating, affecting the normal operation and service life of the equipment, and increasing the failure rate and maintenance costs.

[0005] 3. Complex structure: To solve the heat dissipation problem, the industry usually adds multiple fans or heat dissipation devices, which leads to complex equipment structure, high manufacturing and maintenance costs, and occupies more space, affecting the overall design of the equipment and user experience.

[0006] In order to solve the above problems, the following methods are usually adopted:

[0007] 1. Increase the number of cooling fans: By adding multiple cooling fans at different locations inside the device, heat dissipation efficiency can be improved. However, this approach increases the structural complexity and manufacturing cost of the device, and the noise generated by multiple fans can also cause discomfort to users.

[0008] 2. Use high-efficiency heat dissipation materials: Use high-efficiency heat-conducting materials, such as aluminum heat sinks, inside the device to improve heat dissipation. Although this method can improve heat dissipation to a certain extent, the cost of high-efficiency heat dissipation materials is high and it still cannot solve the problem of uneven heat dissipation.

[0009] 3. Improve equipment structure design: By redesigning the internal structure of the equipment to optimize the airflow path and improve heat dissipation, this approach requires extensive experimentation and adjustments, resulting in a long design cycle and often failing to achieve the desired results.

[0010] Therefore, how to improve the overall heat dissipation efficiency of the pizza oven, reduce the temperature rise of the equipment, and ensure the stability of key components has become the technical problem to be solved by the present utility model. Utility Model Content

In an embodiment of the present invention, a pizza oven with high efficiency and synchronous heat dissipation includes an outer shell 1; an inner cavity component, which is arranged in the outer shell 1 and forms an interlayer 3 with the outer shell 1; a door component 4, which is installed in the front of the outer shell 1 and is used to open and close the inner cavity 10; an upper heating element 5 and a lower heating element 6, which are respectively arranged on the upper side 7 and the lower side 8 of the inner cavity 10; a shaded pole motor 9, which extends into the inner cavity 10 through a through hole, and a wind wheel 12 is installed on the motor shaft 11; a cross-flow fan 13, which is arranged in the interlayer 3 between the outer shell 1 and the inner cavity component, and the cross-flow fan 13 is close to the rear cover of the outer shell, and is used to discharge the hot air in the interlayer 3 and drive external air into the interlayer 3; the shaded pole motor 9 is arranged below the cross-flow fan 13 and has an independent air duct chamber 14 for inhaling external air and discharging hot air; a control part component, which is arranged in the heat-insulating cavity of the door component 4 and is connected to the outside through an independent air duct, and the air circulates through the air duct into the door glass cavity and the control board cavity for heat dissipation.

[0042] The crossflow fan 13 has air inlets 22 located at the bottom and sides of the housing 1 for introducing outside air. The crossflow fan 13 has air outlets 15 located at the bottom rear of the housing 1 for exhausting hot air. The door assembly 4 includes a heat shield, a bracket 17, a front cover, a glass cover, a metal ring, a control unit, and a handle 21. The heat shield is fixed to the interior of the door assembly 4. The bracket 17 connects the heat shield and the front cover. The glass cover is located on the inside of the front cover. The metal ring is fixed to the edge of the glass cover. The control unit is installed between the heat shield and the bracket 17, forming a partition with the door assembly 4. The handle 21 is fixed to the outside of the door assembly 4. The door assembly 4 has air inlets 22 and two independent air ducts, which introduce outside air into the door glass cavity and the control board cavity for heat dissipation. The interlayer 3 at the bottom of the control board is connected to the outside, and air passes through the interlayer 3, thereby preventing heat from radiating into the circuit board cavity. The glass cavity has an air inlet on one side and an air outlet on the other side. Air is introduced into the cavity through the air ducts, forming a circulating cooling duct.

[0043] The power board 23 is placed in the interlayer 3 at the rear of the machine and has an independent mounting and cooling chamber. The power box and the power box cover form this independent chamber. A cooling fan 24 is mounted on the power box cover and communicates with the outer casing 1. The outer casing 1 has an air inlet facing the cooling fan 24. The power board 23 is placed on the power box, with a distance from the power board 23 on all sides. The bottom of the power box has a through hole. The cooling fan 24 is used to draw external air from the air inlet into the power box chamber to cool the power board 23 and exhaust the hot air through the through hole. The entire machine's heat dissipation duct 25 includes a crossflow fan 13 and a shaded-pole motor 9. The crossflow fan 13 is located in the interlayer 3 between the outer casing 1 and the inner chamber assembly, and is closely attached to the rear cover of the outer casing. The shaded-pole motor 9 is located below the crossflow fan 13 and has an independent air duct chamber 14, which is distanced from the outer casing 1.

[0044] Example 1:

[0045] This utility model relates to a highly efficient, synchronized heat dissipation pizza oven, designed to address the problems of low heat dissipation efficiency, high equipment temperatures, overheating of key components, and complex structures in conventional pizza ovens. The following describes the implementation of this technical solution in detail through specific application scenarios.

[0046] In commercial kitchen environments, pizza ovens often operate at high temperatures for extended periods of time. Traditional pizza ovens use a single fan for heat dissipation, but this inefficiency and uneven heat distribution can lead to overheating of key components such as circuit boards and door assemblies, impacting equipment performance and lifespan.

[0047] This pizza oven achieves efficient heat dissipation by forming a sandwich 3 between the outer shell 1 and the inner chamber assembly, and installing a crossflow fan 13 and a shaded-pole motor 9 within this sandwich 3. The crossflow fan 13, mounted close to the rear cover of the outer shell, is used to exhaust hot air from the sandwich 3 and continuously draw in cool air from the outside. The shaded-pole motor 9, located below the crossflow fan 13, draws in external air through a separate air duct chamber 14 and exhausts the hot air.

[0048] In practice, when the pizza oven is turned on and reaches operating temperature, the upper and lower heating elements 5, 6 within the inner chamber assembly generate a significant amount of heat. At this point, the crossflow fan 13 begins to operate, rapidly exhausting the hot air from the interlayer 3 between the inner chamber 10 and the outer shell 1. Because the crossflow fan 13 is in close contact with the rear cover of the outer shell, the heat removal process is smoother, efficiently removing heat from the oven. Simultaneously, cool air from the outside enters the interlayer 3 through the air inlets 22 on the bottom and sides of the outer shell 1, continuously replenishing cooling air within the oven.

[0049] The shaded-pole motor 9 starts simultaneously with the crossflow fan 13, and its independent air duct chamber 14 ensures continuous intake of cool air and efficient exhaust of hot air. This not only improves the heat dissipation efficiency of the entire machine, but also prevents the accumulation of hot air inside the furnace, thus avoiding overheating of key components.

[0050] Door assembly 4 features a multi-layered design, including a heat shield, bracket 17, front cover, and glass cover. The heat shield is secured within door assembly 4, with bracket 17 connecting the two. The glass cover is positioned inside the front cover, with a metal ring secured to the edge of the glass cover. The control unit is installed between the heat shield and bracket 17, separating it from door assembly 4. Handle 21 is secured to the outside of door assembly 4. Door assembly 4 is equipped with an air inlet 22 and independent air ducts to draw cold air from the outside into the door glass cavity and control panel cavity, achieving effective heat dissipation and thermal insulation.

[0051] In actual use, when the pizza oven is operating, the heat dissipation duct 25 of the door assembly 4 draws in outside air through the air inlet 22 and directs the cool air into the door glass cavity and the control panel cavity through the duct, effectively blocking the heat radiation and keeping the control panel and door glass cool. This not only ensures the safety of the equipment, but also extends the service life of the control panel.

[0052] The power board 23 is housed in a separate compartment 3 at the rear of the machine. A cooling fan 24 draws in outside air through the air inlet of the housing 1, cooling the power board 23 and exhausting the hot air through the through-holes. A distance is maintained between the power board 23 and the power box to ensure adequate cooling air circulation and maintain the stability of the power board 23 during extended operation.

[0053] Through the above design, the pizza oven of the utility model can effectively improve the heat dissipation efficiency, significantly reduce the temperature rise of the equipment, and ensure the stability and service life of key components in a long-term high-temperature working environment.

[0054] In the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and the like should be understood in a broad sense.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
