[0002] Food roasting equipment utilizes high temperatures to process and roast food. Common examples include electric ovens, roast duck ovens, multi-functional barbecue carts, meat grills, smokeless barbecue machines, and pizza ovens, making them an important part of the modern catering industry. A pizza oven, in particular, is a processing device used to bake pizzas. It typically employs a chain conveyor system to transport the pizzas, heating them from above and below. In practical applications, it is also used for roasting items such as foil-wrapped food, egg tarts, steaks, and grilled fish.

[0003] In existing technologies, if the food being grilled is high in oil, it easily vaporizes at high temperatures, producing fumes that negatively impact the environment and grilling quality, and can also cause internal oil buildup. To address this, researchers have designed a solution involving a drip tray under the food to collect dripping oil. However, this solution conflicts with the heating mechanism beneath the food, which is then eliminated, impacting grilling efficiency and quality. Furthermore, the drip tray cannot completely prevent the vaporization of dripping oil, thus limiting its effectiveness. Utility Model Content

[0044] Food roasting equipment utilizes high temperatures to process and roast food. Common examples include electric ovens, roast duck ovens, multi-functional barbecue carts, meat grills, smokeless barbecue machines, and pizza ovens, making them an important part of the modern catering industry. A pizza oven, in particular, is a processing device used to bake pizzas. It typically employs a chain conveyor system to transport the pizzas, heating them from above and below. In practical applications, it is also used for roasting items such as foil-wrapped food, egg tarts, steaks, and grilled fish.

[0045] In existing technologies, if the food being grilled is high in oil, it easily vaporizes at high temperatures, producing fumes that negatively impact the environment and grilling quality, and can also cause internal oil buildup. To address this, researchers have designed a solution involving a drip tray under the food to collect dripping oil. However, this solution conflicts with the heating mechanism beneath the food, which is then eliminated, impacting grilling efficiency and quality. Furthermore, the drip tray cannot completely prevent the vaporization of dripping oil, thus limiting its effectiveness.

[0046] Therefore, this utility model provides a pizza oven that can solve the problem of oil fume generation.

[0047] Reference Figures 1 to 8This utility model discloses a pizza oven, comprising an oven body 100, a drip tray 300, and a temperature control chamber 400. Specifically, the oven body 100 is equipped with a food conveying mechanism 200, used to convey the food to be baked into the oven body 100 for baking and to remove the baked food. The drip tray 300 is disposed inside the oven body 100 and directly below the food conveying mechanism 200, used to collect substances dripping from the food, such as grease produced during baking, washing water dripping from the food, and liquid seeping from the fresh food itself. The temperature control chamber 400 has an internal cavity for containing a cooling medium. The temperature control chamber 400 covers the bottom of the drip tray 300 and / or the outer peripheral wall of the drip tray 300, used to control the temperature of the drip tray 300.

[0048] During operation, the food conveying mechanism 200 transports the food that needs to be roasted. When there is dripping oil or water on the food, it is collected by the oil collection tray 300 below. Cooling medium is introduced into the temperature control box 400 to keep the temperature of the oil collection tray 300 from rising as the roasting time increases, thereby preventing the oil in the oil collection tray 300 from vaporizing and producing oil fumes.

[0049] The cooling medium in this embodiment can be flexibly set as needed, such as cooling water, cooling gas, or other materials.

[0050] Therefore, the pizza oven in this embodiment solves the problem in the prior art that the oil receiving pan 300 cannot completely prevent the vaporization of dripping grease and the generation of smoke, and can completely achieve smokeless operation, which plays an important role and significance in improving the on-site environment and improving product quality.

[0051] Reference Figure 2 and Figure 3 In some embodiments of this utility model, the temperature control box 400 is connected to a water outlet pipe 402, the input end of which is connected to a position near the top of the cavity. The water outlet pipe 402 is used to discharge the cooling medium in the cavity, realizing the replacement or flow of the cooling medium. When cooling water is used as the cooling medium, the temperature control box 400 and the oil receiving pan 300 will be heated by the internal heating of the furnace body 100, and scale may form in the cooling water in the cavity. In this embodiment, by connecting the input end of the water outlet pipe 402 to a position near the top of the cavity, scale can be effectively prevented from clogging the water outlet pipe 402 and affecting the discharge and circulation of cooling water. Similarly, when other cooling media are used, connecting the water outlet pipe 402 to a position near the top of the cavity can also effectively prevent clogging.

[0052] Reference Figure 2 and Figure 3In some embodiments of this utility model, the water outlet pipe 402 is inserted into the cavity from the bottom upwards of the temperature control box 400, with its upper end close to the top of the cavity. When there are different heights inside the cavity, it is preferable to place the water outlet pipe 402 at the higher position in the cavity to improve the anti-clogging effect. Using the structural arrangement of this embodiment, by extending the water outlet pipe 402 from the bottom upwards of the temperature control box 400, it is beneficial to reduce the floor space occupied and will not interfere with the setting of the oil receiving tray 300.

[0053] Reference Figure 2 and Figure 3 In some embodiments of this utility model, the temperature control box 400 is connected to a water inlet pipe 401, and the output end of the water inlet pipe 401 is connected to a position near the top of the cavity. Similar to the aforementioned embodiments, this embodiment, by connecting the output end of the water inlet pipe 401 to the top area of ​​the cavity, can effectively prevent it from being blocked by scale or other impurities in the cavity, thereby ensuring smooth circulation of the cooling medium.

[0054] Reference Figure 2 and Figure 3 In some embodiments of this utility model, the water inlet pipe 401 is inserted into the cavity from the bottom upwards of the temperature-controlled box 400, with its upper end close to the top of the cavity. Furthermore, when there are different heights inside the cavity, the water inlet pipe 401 is positioned at the higher end of the cavity to improve the anti-clogging effect.

[0055] Reference Figure 2 and Figure 3 Furthermore, the inlet pipe 401 and the outlet pipe 402 are located on opposite sides of the cavity. This ensures that after the cooling medium is sent into the cavity through the inlet pipe 401, the flow range can radiate throughout the cavity, and then it is discharged from the outlet pipe 402, which can effectively ensure the temperature control effect of the docking oil pan 300.

[0056] In some embodiments of this utility model, the oil receiving tray 300 is disposed on the top of the temperature control box 400 and protrudes downward from the top of the cavity, so that the temperature control box 400 simultaneously covers the bottom and circumferential sidewalls of the oil receiving tray 300. With this structural configuration, the cavity surrounds the perimeter and bottom of the oil receiving tray 300. When the cooling medium flows through, it can simultaneously cool and control the temperature of the perimeter and bottom of the oil receiving tray 300, preventing the oil receiving tray 300 from overheating and causing the contained grease to vaporize and produce fumes.

[0057] In some embodiments of this utility model, the oil receiving tray 300 and the temperature control box 400 are connected as an integral structure to simplify the structural composition.

[0058] In some embodiments, an oil receiving tray 300 is formed by recessing the upper end face of the temperature control box 400, and the temperature control box 400 as a whole is a welded and sealed box structure. This structural design ensures both the overall sealing of the temperature control box 400 and effective contact between the cooling medium and the oil receiving tray 300, achieving the effect of cooling and temperature control. Furthermore, the structure is simple and convenient for production.

[0059] Reference Figure 2 and Figure 3 Furthermore, in this embodiment, the inlet pipe 401 and outlet pipe 402 are located within the cavities on the left and right sides of the oil receiving pan 300. Since the cavities surround both the periphery and bottom of the oil receiving pan 300, when the cooling medium is introduced into the cavity via the inlet pipe 401, it can flow from the periphery and bottom of the oil receiving pan 300 towards the outlet pipe 402, and finally be discharged through the outlet pipe 402, thereby ensuring effective cooling and temperature control. Based on this, both the inlet pipe 401 and outlet pipe 402 are inserted vertically upwards into the cavity and protrude from the bottom of the cavity, so that their upper ends are close to the top of the cavity where they are located, thereby avoiding impurities that may exist at the bottom of the cavity and preventing pipe blockage.

[0060] Combination Figure 3 As shown, the upper ends of the inlet pipe 401 and the outlet pipe 402 are set as pointed structures. Compared with the radial cross-section structure, the pointed structure shown in the figure increases the port size and the distance between the port and the top of the cavity. At the position of the inlet pipe 401, it is conducive to the rapid diffusion of the cooling medium into the cavity, and at the position of the outlet pipe 402, it is conducive to the rapid entry of the cooling medium into the outlet pipe 402.

[0061] It should be noted that the cooling medium does not need to completely fill the cavity, so the outlet pipe 402 is located to facilitate the overflow of the cooling medium. When cooling water is used as the cooling medium, if steam is generated in the cavity due to the heating of the cooling water, the outlet pipe 402 located near the top also facilitates the rapid discharge of steam, preventing pressure build-up inside the cavity and helping to ensure the safety of the equipment.

[0062] Reference Figure 3 In some embodiments of this utility model, the bottom of the oil receiving tray 300 is connected to an oil drain pipe 403 for discharging the contained grease through the oil drain pipe 403. Furthermore, the output end of the water outlet pipe 402 is connected to the oil drain pipe 403 to send drainage into the oil drain pipe 403. Cooling water is used to flush the drain pipe. Due to the heating of the cooling water and the steam generated within the cavity, the drainage has a certain pressure, achieving a heating and flushing effect and preventing grease from condensing and caking inside the oil drain pipe 403.

[0063] Based on this, the water supply direction from the outlet pipe 402 to the oil drain pipe 403 forms an angle of less than or equal to 90° with the oil drain direction of the oil drain pipe 403, thereby ensuring that the oil-water mixture after rinsing can be quickly discharged from the oil drain pipe 403, avoiding the problem of backflow of rinsing water into the oil drain pipe 403.

[0064] It should be noted that when other components are used as the cooling medium, the connection of the oil drain pipe 403 can be selected as needed.

[0065] In some embodiments of this utility model, the water outlet pipe 402 is equipped with a valve for controlling its opening and closing, thereby controlling the connection and disconnection between the water outlet pipe 402 and the oil drain pipe 403. The valve can be configured as a timed opening and closing mechanism, such as automatically opening after the furnace body 100 has been in operation for a set period of time, to achieve cavity depressurization and cleaning of the oil drain pipe 403; it can also be configured as an automatic opening and closing mechanism based on the pressure within the cavity, such as automatically opening when the pressure within the cavity reaches a set value, to achieve cavity depressurization and cleaning of the oil drain pipe 403; or it can be a manually operated opening and closing mechanism.

[0066] Furthermore, considering that the water outlet pipe 402 may overflow, the water outlet pipe 402 can be provided with another outlet for drainage, and connected to the oil drain pipe 403 through a bypass pipe.

[0067] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of this utility model, the oven body 100 is further provided with a heating mechanism 500, which includes a hot air supply unit, an upper air duct 501, and a lower air duct 502. The hot air supply unit is used to output hot air to provide a heat source for baking food. The upper air duct 501 is located above the food conveying mechanism 200 and is connected to the hot air supply unit for supplying hot air to the food conveying mechanism 200. The lower air duct 502 is located on at least one side below the food conveying mechanism 200 and is connected to the hot air supply unit for supplying hot air to the food conveying mechanism 200.

[0068] The structural design of this embodiment utilizes hot air for baking. Compared to placing heating elements above and below the food, this design directly avoids the space beneath the food, allowing grease or other substances to drip into the drip tray 300 below, while ensuring baking effect and efficiency. The upper air duct 501 is directly above the food conveying mechanism 200, delivering hot air downwards to ensure efficient baking. The lower air duct 502 is located beside the food conveying mechanism 200, delivering hot air towards the food while avoiding the area directly beneath it, resulting in uniform temperature and consistent heating of the food area, thus ensuring baking quality.

[0069] It is understandable that the hot air supply unit can be configured according to existing technologies as needed, and no specific limitations are made here. The downdraft duct 502 can be located on one side of the food conveying mechanism 200, or on both sides, or in other locations.

[0070] Reference Figure 6 In some embodiments of this utility model, the upper air duct 501 includes an upper air box 5011 and an air guide plate 5012. Specifically, one end of the upper air box 5011 is connected to the hot air supply unit, so that the hot air delivered by the hot air supply unit directly enters the interior of the upper air box 5011. The other end of the upper air box 5011 extends along the conveying direction perpendicular to the food conveying mechanism 200. The lower end face of the upper air box 5011 remains horizontal and is provided with multiple air outlets 5013, so that the hot air covers the entire width direction of the food conveying mechanism 200. The height of the upper air box 5011 decreases along the direction away from the hot air supply unit. The air guide plate 5012 is disposed inside the upper air box 5011. One end of the air guide plate 5012 is located at the port of the upper air box 5011 that connects to the hot air supply unit, and the distance from the air guide plate 5012 to the lower end face of the upper air box 5011 decreases along the direction away from the hot air supply unit. That is, the air guide plate 5012 is inclined relative to the horizontal plane, and the height of the end of it closer to the hot air supply part is higher than the height of the end of it farther away from the hot air supply part.

[0071] In this embodiment, the port of the upper air box 5011 connected to the hot air supply unit forms multiple vertically distributed flow channels through the air guide plate 5012. Both the upper end of the upper air box 5011 and the air guide plate 5012 are inclined downwards away from the hot air supply unit, which can quickly guide the hot air downwards to the air outlet 5013 for discharge. Furthermore, the reduced vertical cross-section of the upper air box 5011 helps ensure that the hot air pressure output from each air outlet 5013 is uniform and consistent in the width direction of the food conveying mechanism 200, as well as the synchronicity of the hot air delivery.

[0072] Understandably, one or more air deflectors 5012 can be installed as needed.

[0073] Reference Figure 6In some embodiments of this utility model, the upper air duct 501 further includes an air distribution plate 5014, which is horizontally disposed inside the upper air box 5011. The air distribution plate 5014 is located below the air guide plate 5012, and its horizontal height is lower than the port of the upper air box 5011 that connects to the hot air supply section. The air distribution plate 5014 is provided with multiple air distribution holes, the diameter of which is smaller than that of the air outlet 5013. Using the structure of this embodiment, after hot air is sent into the upper air box 5011, under the combined constraint of the upper air box 5011, the air guide plate 5012, and the air distribution plate 5014, it will first quickly fill the upper space of the air distribution plate 5014, then pass through the air distribution plate 5014 into the space between the lower end face of the air distribution plate 5014 and the upper air box 5011, and finally be evenly discharged from the air outlet 5013 of the upper air box 5011. Figure 6 As shown, the space between the air distribution plate 5014 and the lower end face of the upper air box 5011 is a cuboid space, so the internal hot air can maintain uniform pressure, thereby ensuring that the hot air discharged from below is uniform and consistent.

[0074] Since the food conveying mechanism 200 has a certain conveying length, multiple upper air ducts 501 can be set along the conveying direction of the food conveying mechanism 200 to ensure the uniformity of the heating temperature along the conveying direction of the food conveying mechanism 200.

[0075] Reference Figure 7 In some embodiments of this utility model, the lower air duct 502 includes a lower air box 5021, an air outlet plate 5023, and an adjusting plate 5024. The lower air box 5021 is connected to the hot air supply unit, allowing the hot air supplied by the hot air supply unit to directly enter the interior of the lower air box 5021. An air outlet channel 5022 is provided in the lower air box 5021 facing the food conveying mechanism 200. The length direction of the air outlet channel 5022 is consistent with the conveying direction of the food conveying mechanism 200, thereby discharging air along the entire range of the food conveying mechanism 200. The air outlet plate 5023 is disposed inside the lower air box 5021, dividing the lower air box 5021 into a first chamber and a second chamber. The first chamber is close to the air outlet channel 5022, and the second chamber is close to the hot air supply unit. Along the conveying direction of the food conveying mechanism 200, the air outlet plate 5023 is provided with multiple air outlets. The adjusting plate 5024 is movably and adjustablely connected to the air outlet plate 5023. The adjusting plate 5024 is provided with multiple adjusting ports along the conveying direction of the food conveying mechanism 200. During the adjustment process of the adjusting plate 5024, the overlapping area between the adjusting port and the air outlet changes.

[0076] Understandably, when the hot air supply unit sends hot air into the lower air box 5021, it first distributes the air through the air outlet plate 5023, and then sends it out from the air outlet channel 5022 towards the food conveying mechanism 200. During this process, by changing the position of the adjusting plate 5024, the size of the air outlet's flow area can be adjusted, thereby controlling the air volume and thus the heating temperature below.

[0077] In some embodiments, the adjusting plate 5024 is provided with an oblong hole, and the air outlet plate 5023 is connected by a screw passing through the oblong hole. The length direction of the oblong hole is the movement adjustment direction of the adjusting plate 5024.

[0078] In some embodiments, the hot air supply unit is provided with a main air box 503, which is located on one side of the food conveying mechanism 200. The upper end of the main air box 503 is higher than the food conveying mechanism 200, and the lower end of the main air box 503 is lower than the food conveying mechanism 200. The upper air box 5011 and the lower air box 5021 are both horizontally connected to the main air box 503.

[0079] In some embodiments, the food conveying mechanism 200 is provided with two opposing sets of conveyor chains for conveying food. It is understood that in practical applications, only a tray needs to be used to support the food, and then the tray is placed on the two sets of conveyor chains. This tray can be grid-shaped or have other structures.

[0080] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
