Description

Technical Field

[0001] This utility model relates to the field of pizza oven technology, specifically a pizza oven. Background Technology

[0002] A pizza oven is a device specifically designed for baking pizzas. Common types include gas-fired and electric-fired ovens. Gas-fired pizza ovens use natural gas or liquefied petroleum gas to generate heat, resulting in rapid and sufficient heating. Electric pizza ovens use electric heating elements or wires, offering more precise temperature control and easier cleaning. Internally, they have heat-resistant walls and a bottom that can withstand high temperatures and evenly reflect heat, ensuring the pizza is heated evenly. Some high-end pizza ovens also feature a rotisserie grill or baking stone. The rotisserie grill ensures even heating during baking, while the baking stone absorbs and retains heat, resulting in a crispier crust. Pizza ovens are widely used in restaurants, pizzerias, hotels, and other commercial establishments. Small home pizza ovens are also available for convenient pizza making at home.

[0003] Based on the above, the inventors have discovered the following problems: When a pizza oven is in operation, the heat generated by combustion inside the oven tends to diffuse and accumulate inside the outer shell and around the oven. Although ventilation holes are provided at the bottom of the pizza oven to allow heat to dissipate, the hot air cannot circulate and escape quickly and sufficiently. Furthermore, if the pizza oven is placed on a table or countertop, the bottom is in close contact with the surface, and the gap is small, preventing air from carrying away heat smoothly. The ventilation path is restricted, making it even more difficult for heat to dissipate. Long-term heat accumulation may cause the oven to overheat, affecting its lifespan.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a pizza oven with greater practical value. Utility Model Content

[0005] The purpose of this invention is to provide a pizza oven to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A pizza oven includes an oven body and a heat dissipation assembly. The heat dissipation assembly is disposed on the outside of the oven body and is used to actively dissipate heat from the oven body. The oven body includes a chassis, with a plurality of first slots on the outer side wall of the chassis and a plurality of through holes at the bottom end of the chassis. The heat dissipation assembly includes a plurality of air circulation boxes, which are respectively installed on the outer wall of the chassis. Each air circulation box has a second slot on the side near the chassis, and each air circulation hole has a connection port on the side opposite to the second slot. A first connecting seat is internally threaded into the connection port. A connecting cylinder is externally threaded into the first connecting seat at the end away from the connection port. A second connecting seat is internally threaded into the connecting cylinder at the end away from the first connecting seat. A cooling fan is installed at the center of the internal part of the connecting seat.

[0008] Furthermore, adjacent first slots and second slots are aligned with each other and are interconnected. A plurality of first slots are distributed in an equally spaced ring, and a plurality of through holes are distributed in an equally spaced ring. The number of first slots is four.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, since the four first slots are aligned with and connected to the four second slots respectively, a smooth channel for air circulation is provided. When the cooling fan is working, the external air enters the interior of the air circulation box through the connection port and then enters the interior of the chassis through the second slot and the first slot. The hot air inside the chassis is squeezed out through the through hole, forming a convection cooling effect, thereby achieving active cooling and avoiding the phenomenon of heat accumulating at the chassis and not being able to dissipate.

[0010] Furthermore, a first filter screen and a second filter screen are respectively installed at the center of the interior of the first connecting seat and the second connecting seat.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting the first filter screen and the second filter screen inside the first connecting seat and the second connecting seat respectively, impurities are prevented from entering the cooling fan and affecting the normal operation of the cooling fan. At the same time, impurities are also prevented from entering the interior of the pizza oven body through the second connecting seat, the connecting cylinder, the first connecting seat, and the air circulation box, so as to prevent contamination or damage to the internal components of the pizza oven.

[0012] Furthermore, the bottom of the chassis is equipped with several legs, which are distributed in a ring at equal intervals, and the number of legs is four.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by installing four support legs at the bottom of the chassis, the four support legs are evenly distributed in a ring, which can evenly support the chassis and keep the pizza oven stable when placed. At the same time, the support legs separate the chassis from the ground, forming a certain space, so that the hot air inside the chassis can be discharged from the through hole after the outside air enters.

[0014] Furthermore, the upper end of the chassis is provided with a fire bowl assembly, the fire bowl assembly is covered with an outer shell, the upper end of the outer shell is fitted with a top cover, the chassis, the fire bowl assembly and the outer shell are connected by a number of bolts, the number of bolts are distributed in a ring at equal intervals, the inside of the fire bowl assembly is installed with a stove plate support, the top surface of the stove plate support is provided with a placement groove, the inside of the placement groove is provided with a pizza stove plate.

[0015] The beneficial effects of adopting the above-mentioned further solution are that, since the base, the burner assembly, and the outer shell are connected by several bolts arranged in an equidistant ring, the base, the burner assembly, and the outer shell are tightly connected, ensuring the firmness and stability of the connection. At the same time, the bolt connection facilitates disassembly and assembly. When the pizza oven needs to be cleaned, repaired, or parts replaced, the base, the burner assembly, and the outer shell can be disassembled by unscrewing the bolts to maintain their internal components. By opening a placement groove on the top surface of the oven plate support, a precise positioning and stable support are provided for the user to place the pizza oven plate, keeping the pizza oven plate in a fixed position when baking pizzas.

[0016] Furthermore, both the outer shell and the fire bowl assembly have a first opening, the width of which is greater than the width of the pizza oven plate. Both the outer shell and the fire bowl assembly have a second opening on one side. The outer shell is fixedly connected to the heating element at the second opening. A fire baffle is installed on the upper end of the oven plate support near the heating element.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: the first opening on the outer shell and the fire bowl assembly, with a width larger than the pizza oven plate, facilitates the operator to put in and take out the pizza oven plate, making it easier to place the pizza and retrieve it after baking; the second opening on one side of the outer shell and the fire bowl assembly is used to install the heating element, enabling the heating element to efficiently transfer heat to the inside of the fire bowl assembly, providing a sufficient heat source for baking pizza; the baffle plate installed at the upper end of the oven plate support near the heating element can prevent the flames from directly hitting the oven plate support, avoiding damage to the oven plate support due to prolonged exposure to high-temperature flames. At the same time, the baffle plate can also guide and concentrate the flames, making the heat more concentrated on the pizza oven plate, improving heat utilization, and enhancing the baking efficiency and effect of pizza.

[0018] Furthermore, a handle is installed at the upper end of the top cover, and a thermometer is installed at the upper end of the top cover near the handle. The detection end of the thermometer passes through the top cover and the fire bowl assembly and extends into the interior of the fire bowl assembly.

[0019] The beneficial effects of adopting the above-mentioned further solution are that by installing a handle on the top of the lid, users can easily change the position of the pizza oven body by lifting the handle. By setting a thermometer with its detection end located inside the burner assembly, the temperature inside the burner assembly can be monitored in real time. Operators can intuitively understand the temperature inside the oven based on the data displayed by the thermometer, and thus adjust the working status of the heating elements in a timely manner to control the temperature inside the oven within a suitable range, ensuring the accuracy and stability of the temperature during the pizza baking process.

[0020] Furthermore, the heating element consists of a control box, a heat insulation plate, a furnace head, a straight pipe, a regulating valve, a flame outlet, a pulse igniter, an ignition electrode, and a thermocouple.

[0021] The beneficial effects of adopting the above-mentioned further solution are that the connection method between the heating element and the outer shell, and the way the heating element heats the pizza, are all the contents of the pizza oven with patent publication number CN220141440U. The flame outlet is connected to the gas cylinder through an external hose. The burner head is located between the inner wall of the outer shell and the outer wall of the fire bowl assembly and close to the baffle plate. The ignition electrode of the pulse igniter passes through the fire bowl assembly. When gas is supplied in the straight pipe of the burner head, the user presses the button of the pulse igniter to make the end of the ignition electrode continuously generate sparks, thereby generating flames at each through hole in the burner head. The regulating valve connected to the gas cylinder by the external hose is located in the control box, while the knob used to regulate the gas flow through the regulating valve is outside the control box, thus facilitating the user to adjust the gas flow.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: When the pizza oven body is working, the heat generated by combustion, such as gas, is concentrated inside the oven body. It is difficult for hot air to be quickly and effectively discharged through the through holes. By setting up a heat dissipation component, active heat dissipation is achieved, which sends external air into the interior of the chassis, forming a convection heat dissipation effect. This allows the hot air to be quickly discharged from the chassis to the outside through the through holes under the continuous influx of external air into the chassis. By setting up four cooling fans, all of the same model (Jamicon KF0B10B5LR), and the fan blades of the four cooling fans rotating in the same direction, the air outlets of the cooling fans are close to the first connecting seat, and the air inlets of the cooling fans are close to the second connecting seat. When the four cooling fans work simultaneously, the external air passes through the second connecting seat, the first connecting seat, the air circulation box, the second slot, and the first slot in sequence under the action of the cooling fans, and finally enters the chassis. The air is actively blown into the chassis, forcing air circulation and increasing the airflow speed, so that the hot air is quickly discharged from the chassis to the outside through the through holes.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 This utility model provides a technical solution: a pizza oven, including a pizza oven body 1 and a heat dissipation component 3. The heat dissipation component 3 is disposed on the outside of the pizza oven body 1 and is used to actively dissipate heat from the pizza oven body 1. The pizza oven body 1 includes a base 11, with a plurality of first slots 12 formed on the outer side wall of the base 11 and a plurality of through holes 13 formed at the bottom end of the base 11. The heat dissipation component 3 includes a plurality of air circulation boxes 31, which are respectively installed on the outer wall of the base 11. The plurality of air circulation boxes 31 have second slots 32 formed on the side near the base 11. The plurality of air circulation holes 13 each have a connection port on the side opposite to the second slots 32. The connection port is internally threaded with a first connecting seat 33. The first connecting seat 33 is externally threaded with a connecting cylinder 34 at the end away from the connection port. The connecting cylinder 34 is internally threaded with a second connecting seat 35 at the end away from the first connecting seat 33. A cooling fan is installed at the center of the connection seat. When the pizza oven body 1 is working, the pizza oven is heated by combustion, for example by using fuel. The heat generated by the gas accumulates inside the furnace body. The hot air cannot be quickly expelled through the through-hole 13 alone. By installing the heat dissipation component 3, active heat dissipation is achieved, sending external air into the interior of the chassis 11 to create a convection cooling effect. This allows the hot air to be rapidly expelled from the chassis 11 through the through-hole 13 under the continuous influx of external air. Four identical Jamicon KF0B10B5LR fans are installed, with all four fan blades rotating in the same direction. The fan outlets are located near the first connecting seat 33, and the fan inlets are near the second connecting seat 35. When all four fans operate simultaneously, external air passes sequentially through the second connecting seat 35, the first connecting seat 33, the air circulation box 31, the second slot 32, and the first slot 12 before entering the chassis 11. This active blowing of air into the chassis 11 forces airflow, increases air circulation speed, and allows the hot air to be quickly expelled from the chassis 11 through the through-hole 13.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 This utility model provides a technical solution: adjacent first slots 12 and second slots 32 are aligned with each other and are interconnected. A plurality of first slots 12 are arranged in an equidistant ring, and a plurality of through holes 13 are arranged in an equidistant ring. There are four first slots 12. A first filter 36 and a second filter 37 are respectively installed at the center of the inner part of the first connecting seat 33 and the second connecting seat 35. A plurality of legs are installed at the bottom of the chassis 11, all arranged in an equidistant ring. Since the four first slots 12 are aligned with and connected to the four second slots 32, a smooth channel for air circulation is provided. When the cooling fan is working, external air enters the air circulation box 31 through the connection port and then enters the chassis 11 through the second slots 32 and the first slots 12, thus cooling the interior of the chassis 11. Hot air is forced out through the through-hole 13, creating a convection cooling effect and thus achieving active heat dissipation. This prevents heat from accumulating at the base 11 and being unable to dissipate. By setting the first filter 36 and the second filter 37 inside the first connecting seat 33 and the second connecting seat 35 respectively, impurities are prevented from entering the cooling fan and affecting its normal operation. At the same time, impurities are also prevented from entering the pizza oven body 1 through the second connecting seat 35, connecting cylinder 34, first connecting seat 33, and air circulation box 31, which could contaminate or damage the internal components of the pizza oven. The four support legs installed at the bottom of the base 11 are evenly distributed in a ring shape, which can evenly support the base 11 and keep the pizza oven stable when placed. At the same time, the support legs separate the base 11 from the ground, forming a certain space, so that the hot air inside the base 11 can be discharged through the through-hole 13 after the outside air enters.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-5This utility model provides a technical solution: a fire bowl assembly 17 is provided at the upper end of the chassis 11, and a shell 14 is fitted over the fire bowl assembly 17. A top cover 15 is installed at the upper end of the shell 14. The chassis 11, the fire bowl assembly 17, and the shell 14 are connected by a number of bolts, which are distributed in a ring at equal intervals. A stove plate support 18 is installed inside the fire bowl assembly 17. A placement groove is opened on the top surface of the stove plate support 18, and a pizza stove plate 110 is placed inside the placement groove. A first opening 111 is opened on the upper part of both the shell 14 and the fire bowl assembly 17. The width of the first opening 111 is larger than the width of the pizza stove plate 110. A second opening 111 is opened on one side of both the shell 14 and the fire bowl assembly 17. 12. The outer shell 14 is fixedly connected to the heating element 2 at the second opening 112. A baffle plate 19 is installed on the upper end of the oven plate support 18 near the heating element 2. A handle 16 is installed on the upper end of the top cover 15. A thermometer 113 is installed on the upper end of the top cover 15 near the handle 16. The detection end of the thermometer 113 passes through the top cover 15 and the burner assembly 17 and extends into the interior of the burner assembly 17. The heating element 2 consists of a control box, heat insulation plate, burner head, straight pipe, regulating valve, flame outlet, pulse igniter, ignition electrode, and thermocouple. When the pizza oven needs cleaning, maintenance, or parts replacement, the chassis 11, burner assembly 17, and outer shell 14 are disassembled by unscrewing the bolts. The internal components are maintained by a slot on the top surface of the oven tray support 18, which provides precise positioning and stable support for the user to place the pizza oven tray 110, keeping the pizza oven tray 110 in a fixed position during pizza baking. The first opening 111 on the outer shell 14 and the fire bowl assembly 17 is wider than the pizza oven tray 110, making it easy for operators to put in and take out the pizza oven tray 110, facilitating the placement of pizzas and their removal after baking. The second opening 112 on one side of the outer shell 14 and the fire bowl assembly 17 is used to install the heating element 2, enabling the heating element 2 to efficiently transfer heat to the inside of the fire bowl assembly 17, providing sufficient heat for baking pizzas. The upper end of the oven tray support 18 is close to... The baffle plate 19 installed near the heating element 2 can prevent the flames from directly hitting the oven plate support 18, avoiding damage to the oven plate support 18 due to prolonged exposure to high-temperature flames. At the same time, the baffle plate 19 can also guide and concentrate the flames, making the heat more concentrated on the pizza oven plate 110, improving heat utilization and enhancing the baking efficiency and effect of the pizza. By setting a thermometer 113, the detection end of the thermometer 113 is located inside the burner assembly 17, so that the temperature inside the burner assembly 17 can be monitored in real time. The operator can intuitively understand the temperature inside the oven based on the data displayed by the thermometer 113, and thus adjust the working state of the heating element 2 in a timely manner to control the temperature inside the oven within a suitable range.

[0035] Specifically, the working principle of this pizza oven is as follows: During use, the pizza dough is fed into the pizza oven body 1 through the first opening 111 and placed on the pizza oven plate 110. Simultaneously, an external hose connects the outlet of the regulating valve to the gas cylinder. A knob for adjusting the gas flow through the regulating valve is located outside the control box, allowing the user to easily adjust the gas flow. Once gas is supplied to the straight pipe of the oven head, the user presses the button on the pulse igniter, causing continuous sparks at the end of the ignition electrode, thus generating flames at the through-holes 13 inside the oven head to bake the pizza dough. The temperature inside the burner assembly 17 is monitored in real time by the thermometer 113, allowing the operator to adjust the temperature accordingly. According to the data displayed by thermometer 113, the temperature inside the oven can be directly observed, allowing for timely adjustment of the working status of heating element 2 to control the oven temperature within a suitable range. When the pizza oven body 1 is working, the heat generated by combustion, such as using gas, accumulates inside the oven. Hot air cannot be quickly and effectively expelled through the through-hole 13 alone. By setting up heat dissipation component 3, active heat dissipation is achieved, sending external air into the interior of the chassis 11 to create a convection cooling effect. This allows hot air to be quickly expelled from the chassis 11 through the through-hole 13 under the continuous influx of external air. Four identical Jamicon cooling fans are also installed. The four cooling fans (KF0B10B5LR) have the same internal fan speed and direction. The air outlet of the cooling fan is close to the first connecting seat 33, and the air inlet of the cooling fan is close to the second connecting seat 35. When the four cooling fans work at the same time, the external air passes through the second connecting seat 35, the first connecting seat 33, the air circulation box 31, the second slot 32, and the first slot 12 in sequence under the action of the cooling fans and finally enters the chassis 11. The air is actively blown into the chassis 11, which forces air circulation and increases the air flow speed, so that the hot air is quickly discharged from the outside of the chassis 11 through the through hole 13. At the same time, the four support legs installed at the bottom of the chassis 11 are evenly distributed in a ring shape, which can evenly support the chassis 11, so that the pizza oven is stable when placed. The support legs also separate the chassis 11 from the ground, forming a certain space, so that the hot air in the chassis 11 is discharged from the through hole 13 after the external air enters.

[0036] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
