Description
Technical Field
[0001] The utility model relates to the technical field of cooking equipment, in particular to an oven. Background Art
[0002] The electric heating tubes in the oven for cooking pizza are usually exposed above the pizza, which can easily cause uneven heating and flash fire in the cavity. Since different parts of the pizza have different requirements for the heat, different heating temperatures are required for different parts of the pizza. The world-famous Neapolitan pizza has the following characteristics: the bottom of the pizza is hard and crispy but not burnt, with only a little yellow crust, so a pizza stone with a temperature-controlled bottom is needed to prepare a crispy pizza bottom by conducting heat, and a high temperature is needed to bake the leopard pattern in a short time; but at the same time, the filling in the middle of the pizza only needs a little burnt on the surface, so the heat required in the middle of the pizza is less than the heat on the periphery, but most of the high-temperature pizza ovens on the market currently have an upper and lower electric heating tube structure, with an electric heating tube at the bottom, a pizza stone on the top, and an electric heating tube on the top. When actually making pizza, leopard patterns will appear around, but the seasoning in the middle will be overheated and burnt; at the same time, in the actual cooking process, the meat on the pizza will spray grease, and if the sprayed grease touches the red electric heating tube, it will flash, which is easy to damage the device and cause a fire in the oven, and the safety performance of the oven is affected. At the same time, the seasoning will also spray onto the upper electric heating tube, making it difficult to clean the electric heating tube. Utility Model Content
[0003] In order to solve the above problems existing in the prior art, the utility model provides an oven, comprising a shell and a heating cavity arranged inside the shell, a first heating element is connected to the top of the heating cavity, the first heating element provides a heat source for the upper part of the heating cavity, a second heating element is connected to the bottom of the heating cavity, the second heating element provides a heat source for the lower part of the heating cavity;
[0004] A heat transfer medium is placed between the first heating element and the second heating element, and the heat transfer medium has a heat conduction function. When cooking, the cooking product is placed on the heat transfer medium. The heating cavity is used to support the heat transfer medium and fix other devices.
[0005] An anti-flash fire device is provided between the first heating element and the heat transfer medium. The anti-flash fire device reserves heating channels of different sizes or heating channels with different distribution densities between the cooking product and the first heating element, so that the heating temperature of the middle and the periphery of the cooking product is different. The anti-flash fire device provides anti-flash fire protection for the first heating element and has the effect of uniformly heating the cooking product.
[0006] Preferably, the anti-flash fire device reserves heating channels of different sizes between the cooking product and the first heating element, specifically comprising: the size of the heating channel in the central part of the anti-flash fire device is smaller than that in the part from the central part to the edge of the anti-flash fire device.

The cooperation mode of the above-mentioned anti-flash fire device and the first heating element can protect the reddened first heating element from being touched by the grease sprayed by the cooking product below due to heating during cooking, which causes the first heating element to flash, thereby causing dangerous phenomena such as fire in the furnace; at the same time, the seasoning on the cooking product during the cooking process will also splash onto the first heating element, making the first heating element difficult to clean. The coordination setting of the anti-flash fire device and the first heating element can make the grease and seasoning sprayed by the cooking product during the cooking process splash on the anti-flash fire device, thereby protecting the first heating element. In addition, it can also prevent the hot light emitted by the first heating element from directly irradiating the cooking product, and heat is transferred through the through hole, so as to achieve a uniform heating effect without reducing the heating effect.
[0011] Further preferably, on the one hand, the aperture size of the through hole is set according to different local temperature requirements of the cooking product, and the intensity of heat transfer is controlled by changing the aperture size of the through hole. Specifically, the aperture size of the through hole is smaller in the central part of the anti-flash fire device than in the part from the central part to the edge of the anti-flash fire device; on the other hand, the layout of the through holes is set according to different local temperature requirements of the cooking product, and the intensity of heat transfer is adjusted by different densities of the through holes distributed on the anti-flash fire device. Specifically, when the through holes have the same size, the through holes are more densely arranged in the central part to the edge of the anti-flash fire device than in the central part of the anti-flash fire device.
[0012] Further preferably, the cooking product is pizza, the anti-flash fire device is not provided with the through hole at the position where it cooperates with the first heating element, and the aperture of the through hole is smaller in the center of the anti-flash fire device than in the center to the edge of the anti-flash fire device, or the through holes are arranged more densely in the center to the edge of the anti-flash fire device than in the center of the anti-flash fire device. The cooking requirements of pizza are: the pizza bottom is hard and crispy but not burnt, with only a little yellow crust, so a pizza stone with a temperature-controlled bottom is required to prepare a crispy pizza bottom by heat conduction, and a leopard pattern needs to be baked in a short time at high temperature; but at high temperature, the filling in the middle of the pizza only needs to be a little burnt on the surface, and the inside should have a thick and flowing feeling, so the heat required in the center of the pizza is less than that in the center to the edge. Therefore, according to the different requirements of different parts of the pizza for the heat, the anti-flash fire device can be provided with different through hole aperture sizes or through hole position layouts with different densities in the center and the peripheral part to meet the different heating temperatures required by different parts of the pizza, that is, the peripheral temperature of the cooking product is higher than the middle temperature.
[0013] Preferably, the anti-flash fire device is detachably mounted on the heating cavity via a connecting device, and the first heating element is also detachably mounted on the heating cavity, so as to facilitate replacement of the anti-flash fire device and the first heating element designed for different cooking temperature requirements.
[0014] Preferably, the anti-flash fire device is configured to be circular or square, or configured to be a corresponding shape according to the requirements of the cooking product.

[0047] Embodiment 1:
[0048] In a specific embodiment, Figures 5 to 7 The first heating element 3 and the anti-flash fire device 6 designed according to the shape of the world-famous Naples pizza and the heating intensity required for each part of the Naples pizza in the oven of Example 1 are shown, and the matching mode of the first heating element 3 and the anti-flash fire device 6 is shown. In this embodiment, the first heating element 3 is an electric heating tube. The requirements of this cooking product are: first, the pizza has a classic round appearance, and second, the filling in the middle of the pizza only needs to be a little bit burnt on the surface while being baked at high temperature, and at the same time, the inside should have a thick and flowing feeling. Therefore, compared with the middle part of the pizza, the periphery of the pizza needs more heat. According to the above characteristics, the design of Example 1 is as follows:
[0049] On the one hand, the first heating element 3 is designed as Figure 5 The shape shown is a circle with the electric heating tube as the shape direction, and no electric heating tube is arranged in the middle, such as Figure 6 The flash fire prevention device 6 shown in the figure is designed such that the diameter of the through hole 7 is smaller in the central part of the flash fire prevention device 6 than in the part from the central part to the edge of the flash fire prevention device 6. The matching design of the first heating element 3 and the flash fire prevention device 6 is as follows: Figure 7As shown, the heating temperature of the pizza periphery can be higher than that of the pizza middle part, thus preventing the pizza from being partially overheated and burnt, or insufficient heat in the local area. Meanwhile, the heat beam can pass through the through hole 7 to achieve the purpose of heat transmission without affecting the heating effect. On the other hand, no through hole is provided at the joint of the first heating element 3 and the anti-flash fire device 6, which effectively prevents the fat of the oily salami sausage on the Naples pizza from spraying grease onto the red electric heating tube and causing a flash fire. It can also prevent the seasoning on the pizza from being sprayed onto the electric heating tube and causing cleaning difficulties. In addition, it can also prevent the heat beam emitted by the electric heating tube from directly irradiating the pizza, thus achieving the purpose of uniform heating.
[0050] Embodiment 2:
[0051] In another specific embodiment, Figures 8 to 10 The first heating element 3 and the anti-flash fire device 6 designed according to the shape of the Roman square pizza and the heating intensity required for each part of the pizza in the oven of Example 2 are shown, and the matching mode of the first heating element 3 and the anti-flash fire device 6 is shown. In this embodiment, the first heating element 3 is an electric heating tube. The requirements of this cooking product are: first, the pizza has a square appearance, and second, the middle of the pizza crust is required to be very thin while baking at high temperature, so the periphery of the pizza requires more heat than the middle part of the pizza. According to the above characteristics, the design of Example 2 is as follows:
[0052] On the one hand, the first heating element 3 is designed as Figure 8 The shape shown in the figure is a rectangular shape of the electric heating tube, and the electric heating tube is not arranged in the middle. On the anti-flash fire device 6, as shown in the figure, Fig. 9 As shown, the diameter of the through hole 7 is designed to be smaller in the central part of the anti-flash fire device 6 than in the part from the central part to the edge of the anti-flash fire device 6. The matching design of the first heating element 3 and the anti-flash fire device 6 is as follows: Fig.10 As shown, the heating temperature of the periphery of the pizza can be higher than that of the middle of the pizza, thereby preventing the pizza from being partially overheated and burnt, or from being insufficiently heated locally. At the same time, the heat rays can pass through the through holes 7 to achieve the purpose of heat transmission without affecting the heating effect. On the other hand, no through hole is provided at the joint of the first heating element 3 and the anti-flash fire device 6, thereby effectively preventing the grease-containing ingredients on the Roman square pizza from spraying the grease onto the red electric heating tube and causing a flash fire. At the same time, it can also prevent the seasoning on the pizza from being sprayed onto the electric heating tube and causing cleaning difficulties. In addition, it can also prevent the heat rays emitted by the electric heating tube from directly irradiating the pizza, thereby achieving the purpose of uniform heating.
[0053] In other embodiments, in addition to adopting the anti-flash fire device 6 in which the aperture of the through hole 7 is smaller in the central part of the anti-flash fire device 6 than in the portion from the central part to the edge of the anti-flash fire device 6 as described in Embodiment 1 and Embodiment 2, an anti-flash fire device 6 can also be adopted in which the through holes are more densely arranged from the central part to the edge of the anti-flash fire device 6 than in the central part of the anti-flash fire device 6, which can also achieve the technical effect of the present invention.
