[0050] The following is for reference. Figures 1-11 The gas oven 1000 according to the present invention can ensure the effective volume of the cooking cavity 204 and reduce the temperature of the high-temperature flue gas, thereby improving the cooking effect and enhancing the user experience.

[0051] like Figures 1-11 As shown, a gas oven 1000 according to an embodiment of the present invention includes: an oven body 200, a combustion module 100, and a fan assembly 40.

[0052] The oven body 200 has a cooking cavity 204 inside. The combustion module 100 is installed on the outside of the oven body 200. The combustion module 100 has an air inlet 50 and a high-temperature flue gas outlet. The combustion module 100 is equipped with a burner 20 and a gas injection assembly 30. The high-temperature flue gas outlet is connected to the cooking cavity 204. The fan assembly 40 is used to supply air to the air inlet 50. The oven body 200 is provided with a cold air flow channel 203. The cold air in the cold air flow channel 203 is suitable to enter the cooking cavity 204 together with the high-temperature flue gas at the high-temperature flue gas outlet.

[0053] The gas oven 1000 can burn gas and heat food with the heat generated by the combustion of gas. The gas oven 1000 can be equipped with a control system that can control the intensity and duration of the flame when the gas is burning, thereby controlling the temperature. The gas oven 1000 has a fast heating speed and high heating efficiency, which can shorten the baking time, improve the efficiency of use, and thus improve the user experience.

[0054] Specifically, the gas oven 1000 is equipped with an oven body 200, which is located on the outermost side of the gas oven 1000. It supports and protects the internal structure of the gas oven 1000 and provides mounting points for the internal structure, ensuring the reliability of the gas oven 1000's operation. The oven body 200 has a cooking cavity 204 inside, which is open on one side. Users can place food into the cooking cavity 204 through the open opening and close the cooking cavity 204 through the oven door of the gas oven 1000 to cook food, ensuring safety and improving the cooking speed.

[0055] Furthermore, a combustion module 100 is provided on the outer side of the oven body 200. The combustion module 100 can be connected to the outer wall of the oven body 200 by welding or connecting parts, which is simple. Preferably, the combustion module 100 can be installed on the rear side of the oven body 200 to avoid burns to the user caused by the high temperature generated during the operation of the combustion module 100, thus ensuring the safety of use. The combustion module 100 can be supplied with gas and can ignite the gas to generate high-temperature gas to heat the food in the cooking cavity 204. The combustion module 100 has an air inlet 50, through which outside air can enter the combustion module 100 to mix with the gas in the combustion module 100, ensuring the complete combustion of the gas.

[0056] In addition, the combustion module 100 is equipped with a burner 20 and a gas injection assembly 30. The gas injection assembly 30 can supply gas into the burner 20, and the air inlet 50 can supply air into the burner 20, so that the air can be mixed with the gas, and then the mixed gas can be ignited to form high-temperature flue gas. The combustion module 100 also has a high-temperature flue gas outlet, which is connected to the cooking chamber 204, so that the high-temperature flue gas generated after the mixed gas is burned can flow into the cooking chamber 204 through the high-temperature flue gas outlet. The high temperature of the high-temperature flue gas is high enough to cook the food and ensure the cooking effect.

[0057] Furthermore, the gas oven 1000 is also equipped with a fan assembly 40. The fan assembly 40 can be connected to the oven body 200 by welding or connecting parts. The fan assembly 40 is used to supply air to the combustion module 100. The fan assembly 40 is connected to the air inlet 50, which is formed in the housing 10 of the combustion module 100. That is, the fan assembly 40 is connected to the combustion module 100, so that the fan assembly 40 can supply air into the combustion module 100 through the air inlet 50, ensuring the reliability of the operation of the combustion module 100.

[0058] Meanwhile, the oven body 200 can also be equipped with a cold air flow channel 203, which can be connected to the outside, allowing outside cold air to circulate into the cold air flow channel 203. The cold air flow channel 203 can also be connected to the high-temperature flue gas outlet, allowing the cold air in the cold air flow channel 203 to mix with the high-temperature flue gas at the high-temperature flue gas outlet, and then both enter the cooking cavity 204. The temperature of the high-temperature flue gas after the combustion of the mixed gas in the combustion module 100 is relatively high, usually reaching 800℃-1000℃. If the high-temperature flue gas at this temperature is directly introduced into the cooking cavity 204 to heat the food, it will cause the food to char. By mixing the cold air with the high-temperature flue gas through the cold air flow channel 203, the high-temperature flue gas can be appropriately cooled down, so that the temperature of the high-temperature flue gas is reduced to below 400℃ before being delivered into the cooking cavity 204, ensuring the cooking effect of the food.

[0059] According to the gas oven 1000 of this utility model embodiment, the combustion module 100 is set on the outside of the oven body 200, which can increase the effective volume of the cooking cavity 204. Furthermore, the cold air and high-temperature flue gas enter the cooking cavity 204 together through the cold air flow channel 203, which can cool down the high-temperature flue gas and avoid the food from being scorched due to excessively high temperature of the flue gas. This ensures uniform cooking and cooking effect, improves user experience, and has a wider range of applications.

[0060] In some embodiments, the high-temperature flue gas outlet is located at the top of the combustion module 100, and the cold air flow channel 203 is located at the top of the oven body 200 and communicates with the high-temperature flue gas outlet.

[0061] Specifically, the combustion module 100 is provided with a high-temperature flue gas outlet, which is located at the top of the combustion module 100. That is, the high-temperature flue gas can flow from the top of the combustion module 100 to the high-temperature flue gas outlet, and then flow into the cooking cavity 204 through the high-temperature flue gas inlet 201. Because of its high temperature and low density, the high-temperature flue gas can naturally flow upward. By placing the high-temperature flue gas outlet at the top of the combustion module 100, the power required to transport the high-temperature flue gas can be reduced, thereby reducing the energy consumption of the gas oven 1000 and ensuring the reliability of the high-temperature flue gas transport.

[0062] Furthermore, such as Figure 5 As shown, the cold air flow channel 203 is located at the top of the oven body 200 and is connected to the high-temperature flue gas outlet. This allows cold air from the outside of the oven body 200 to flow from the top of the oven body 200 to the high-temperature flue gas outlet through the cold air flow channel 203. In actual installation, the cold air flow channel 203 can also be located at the rear of the oven body 200, so that the cold air flow channel 203 can be connected to the mixing channel 2053 through the high-temperature flue gas outlet. This allows cold air from the outside of the oven body 200 to enter the high-temperature flue gas outlet through the cold air flow channel 203, and then enter the mixing channel 2053 through the high-temperature flue gas outlet. The installation method is flexible.

[0063] In some embodiments, the oven body 200 is further provided with a cold air cavity 207, the cold air cavity 207 is provided with a cold air inlet 2071, and the cold air channel 203 is connected to the bottom of the cold air cavity 207.

[0064] Specifically, such as Figure 5 As shown, the oven body 200 also has a cold air cavity 207. The cold air cavity 207 can be set in the upper part, side or bottom of the oven body 200, etc., with flexible setting position. The cold air cavity 207 has a cold air inlet 2071, which is connected to the outside. That is, the cold air from the outside can enter the cold air cavity 207 through the cold air inlet 2071. The connection between the cold air channel 203 and the cold air cavity 207 allows the cold air entering the cold air cavity 207 to circulate into the cold air channel 203. This allows the cold air in the cold air channel 203 to mix with the high temperature flue gas at the high temperature flue gas outlet, so that they can enter the cooking cavity 204 together, avoiding excessively high temperature of the high temperature flue gas and ensuring the cooking effect.

[0065] In addition, the cold air flow channel 203 is connected to the bottom of the cold air cavity 207. Cold air is denser, and after flowing into the cold air cavity 207, it can flow to the bottom of the cold air cavity 207 under the action of gravity. Connecting the cold air flow channel 203 to the bottom of the cold air cavity 207 allows the cold air at the bottom of the cold air cavity 207 to flow directly into the cold air flow channel 203 under the action of gravity, reducing the operating energy consumption of the gas oven 1000 and ensuring the reliability of the cold air delivery by the cold air flow channel 203.

[0066] In some embodiments, the cold air cavity 207 and the cold air flow channel 203 are connected through the impeller cavity 208, and the impeller cavity 208 is provided with an airflow driven impeller 2081.

[0067] Specifically, the oven body 200 is provided with a cold air cavity 207, and the bottom of the cold air cavity 207 is connected to the cold air channel 203, so that outside cold air can be transported into the cold air channel 203 through the cold air cavity 207, and as... Figure 5As shown, the oven body 200 is also provided with a fan chamber 208. The fan chamber 208 is located between the cold air chamber 207 and the cold air channel 203, so that the cold air chamber 207 and the cold air channel 203 are connected through the fan chamber 208. That is, the cold air flowing into the cold air chamber 207 can flow into the fan chamber 208, and then flow into the cold air channel 203 through the fan chamber 208.

[0068] Furthermore, an airflow-driven impeller 2081 is also provided inside the impeller cavity 208. The airflow-driven impeller 2081 can be used to drive the cold air inside the impeller cavity 208, so that the cold air in the cold air cavity 207 can flow into the impeller cavity 208 under the drive of the airflow-driven impeller 2081, and then flow into the cold air flow channel 203, which can ensure the reliability of delivering cold air into the cold air flow channel 203.

[0069] In some embodiments, the oven body 200 is further provided with a smoke exhaust duct 209 communicating with the cooking cavity 204, and a cold air cavity 207 is located at the top of the cooking cavity 204 and is arranged around the smoke exhaust duct 209.

[0070] Specifically, the oven body 200 is provided with a cold air cavity 207, and as... Figure 5 As shown, the cold air cavity 207 is located at the top of the cooking cavity 204, so that the top of the cooking cavity 204 is separated from the outside by the cold air cavity 207. Cold air circulates in the cold air cavity 207, which can cool the top of the oven body 200 to prevent burns to users and ensure safety. The oven body 200 is also provided with a smoke exhaust channel 209, which is connected to the cooking cavity 204, so that the smoke generated in the cooking cavity 204 can be discharged from the cooking cavity 204 through the smoke exhaust channel 209 to ensure the cooking effect.

[0071] Furthermore, the exhaust duct 209 is also located at the top of the oven body 200. High-temperature fumes are generated in the cooking cavity 204 due to cooking. The high-temperature fumes have a low density and can flow towards the top of the cooking cavity 204. Connecting the exhaust duct 209 to the top of the cooking cavity 204 ensures the reliability of the exhaust of high-temperature fumes. The cold air cavity 207 is arranged around the exhaust duct 209, so that as the high-temperature fumes are discharged from the cooking cavity 204 through the exhaust duct 209, the cold air in the cold air cavity 207 can cool down the high-temperature fumes, preventing them from being burned by excessively high temperatures and improving the safety of use.

[0072] In some embodiments, the cold air inlet 2071 is disposed around the smoke exhaust duct 209.

[0073] Specifically, such as Figure 5As shown, the cold air cavity 207 is provided with a cold air inlet 2071, through which outside cold air can enter the cold air cavity 207. The cold air inlet 2071 can be arranged around the exhaust channel 209, that is, when outside cold air enters the cold air cavity 207, it can flow around the exhaust channel 209. The high-temperature fumes in the cooking cavity 204 can be discharged from the cooking cavity 204 through the exhaust channel 209. The arrangement of the cold air inlet 2071 around the exhaust channel 209 allows the cold air to also be arranged around the exhaust channel 209, thereby enabling the cold air to cool the exhaust channel 209 in all directions, ensuring the reliability of cooling, preventing users from being burned by high-temperature fumes, and improving the safety of use.

[0074] In some embodiments, the cold air channel 203 has a cold air inlet 2031 and a cold air outlet 2032. The cold air inlet 2031 is formed at the upper end of the cold air channel 203, and the cold air outlet 2032 is formed at the lower end of the cold air channel 203. The cold air outlet 2032 is connected to the high-temperature flue gas outlet.

[0075] Specifically, the cold air flow channel 203 can deliver cold air to the high-temperature flue gas outlet. The cold air flow channel 203 is provided with a cold air inlet 2031 and a cold air outlet 2032. The cold air inlet 2031 is formed at the upper end of the cold air flow channel 203, so that cold air can enter the cold air flow channel 203 through the upper end of the cold air flow channel 203. The cold air outlet 2032 is formed at the lower end of the cold air flow channel 203 and is connected to the high-temperature flue gas outlet, so that the cold air in the cold air flow channel 203 can flow from the lower end of the cold air flow channel 203 to the high-temperature flue gas outlet. The cold air has a low density and can be transported downward under the action of gravity, thereby reducing the power required to transport the cold air, reducing the operating energy consumption of the gas oven 1000, and ensuring the reliability of the high-temperature flue gas delivery.

[0076] In some embodiments, the cold air channel 203 extends in the vertical direction, and the cold air inlet 2031 is configured to open upward on the top surface of the oven body 200. That is, the upper end of the cold air inlet 2031 is located on the top surface of the oven body 200 and opens upward to communicate with the outside. This allows cold air from the outside to flow into the cold air channel 203 through the upper end of the cold air inlet 2031. The cold air channel 203 extends in the vertical direction, and the cold air has a low density. It can be transported downward along the cold air channel 203 under the action of gravity. This allows the cold air to flow into the mixing channel 2053 through the cold air channel 203, which can reduce the power required to transport the cold air, thereby reducing the energy consumption of the gas oven 1000 and ensuring the reliability of the high-temperature flue gas transport.

[0077] In some embodiments, a mixing channel 2053 is connected between the high-temperature flue gas outlet and the cooking chamber 204, and the cold air channel 203 is connected to the mixing channel 2053.

[0078] Specifically, a mixing channel 2053 connects the high-temperature flue gas outlet and the cooking chamber 204, allowing the high-temperature flue gas entering the cooking chamber 204 through the high-temperature flue gas outlet to circulate along the mixing channel 2053. This causes the high-temperature flue gas to impact the inner wall of the mixing channel 2053 after exiting the high-temperature flue gas outlet, changing both the speed and direction of the high-temperature flue gas. This enhances the turbulence and mixing of the high-temperature flue gas, allowing it to flow more evenly into the cooking chamber 204 and then to the food surface for heating. This avoids the high-temperature flue gas directly hitting the food surface, which could cause the food to burn, thus ensuring cooking results and improving the user experience.

[0079] Furthermore, the cold air flow channel 203 is connected to the mixing flow channel 2053, meaning that the cold air flow channel 203 can transport cold air from the outside to the mixing flow channel 2053, and the high-temperature flue gas outlet can also transport high-temperature flue gas to the mixing flow channel 2053, so that the cold air and high-temperature flue gas can be mixed in the mixing flow channel 2053 to fully cool down the high-temperature flue gas, thereby reducing the temperature of the high-temperature flue gas entering the cooking chamber 204 to the temperature required for cooking, so as to avoid the food from burning due to excessively high temperature of the high-temperature flue gas and improve the cooking effect.

[0080] In some embodiments, the high-temperature flue gas outlet and the cold air flow channel 203 are both connected to the upper part of the mixing flow channel 2053, and the side and / or bottom of the mixing flow channel 2053 are connected to the cooking cavity 204.

[0081] Specifically, such as Figure 1 As shown, both the high-temperature flue gas outlet and the cold air flow channel 203 are connected to the upper part of the mixing flow channel 2053. That is, the high-temperature flue gas outlet can deliver high-temperature flue gas to the upper part of the mixing flow channel 2053, and the cold air flow channel 203 can deliver cold air to the upper part of the mixing flow channel 2053. This allows the cold air and high-temperature flue gas to start mixing in the upper part of the mixing flow channel 2053. The side and / or bottom of the mixing flow channel 2053 are connected to the cooking cavity 204. This means that only the side of the mixing flow channel 2053 is connected to the cooking cavity 204, only the bottom of the mixing flow channel 2053 is connected to the cooking cavity 204, or both the side and the bottom of the mixing flow channel 2053 are connected to the cooking cavity 204. This allows the high-temperature flue gas and cold air to be fully mixed in the mixing flow channel 2053 before flowing into the cooking cavity 204, ensuring the reliability of cooling the high-temperature flue gas.

[0082] In addition, due to its high temperature and low density, the high-temperature flue gas can naturally flow upwards, connecting the bottom of the mixing channel 2053 with the cooking chamber 204. This allows the high-temperature flue gas output from the mixing channel 2053 to flow into the cooking chamber 204 from below and upwards, filling the entire cooking chamber 204. This improves the heating rate of the cooking chamber 204 and the cooking speed of the food, while ensuring the uniformity of food cooking and enhancing the user experience.

[0083] In some embodiments, a mixing channel 2053 is formed inside an oven body 200. The oven body 200 is provided with a high-temperature flue gas inlet 201 that communicates with the mixing channel 2053. The high-temperature flue gas inlet 201 is directly opposite to and communicates with the high-temperature flue gas outlet. A cold air channel 203 is connected between the high-temperature flue gas inlet 201 and the high-temperature flue gas outlet.

[0084] Specifically, the mixing channel 2053 is located inside the oven body 200 and is connected to the cooking cavity 204. The oven body 200 is also provided with a high-temperature flue gas inlet 201, which is connected to the mixing channel 2053. The high-temperature flue gas inlet 201 is directly opposite to and connected to the high-temperature flue gas outlet, so that the high-temperature flue gas generated by the combustion module 100 can flow through the high-temperature flue gas outlet to the high-temperature flue gas inlet 201, and then flow through the high-temperature flue gas inlet 201 into the mixing channel 2053.

[0085] Furthermore, the cold air channel 203 can be connected between the high-temperature flue gas inlet 201 and the high-temperature flue gas outlet. That is, the cold air channel 203 can deliver cold air between the high-temperature flue gas inlet 201 and the high-temperature flue gas outlet, so that the high-temperature flue gas can mix with the cold air when it flows from the high-temperature flue gas outlet to the high-temperature flue gas inlet 201. As a result, the gas flowing into the mixing channel 2053 is a mixture of high-temperature flue gas and cold air. Moreover, the cold air can fully cool down the high-temperature flue gas during the process of being delivered along the mixing channel 2053 into the cooking cavity 204, so that the temperature of the high-temperature flue gas after entering the cooking cavity 204 is suitable for cooking food and improving the cooking effect.

[0086] In some embodiments, the gas oven 1000 further includes a temperature sensor and a control module. The temperature sensor is used to detect the temperature inside the cooking cavity 204, and a control valve is provided in the cold air flow channel 203. The control module is adapted to control the opening degree of the control valve according to the temperature detected by the temperature sensor.

[0087] Specifically, the gas oven 1000 is also equipped with a temperature sensor and a control module. The temperature sensor can be set inside the cooking cavity 204 and can detect the temperature inside the cooking cavity 204. In actual setup, the temperature sensor can be set close to the connection between the mixing channel 2053 and the cooking cavity 204 to ensure the accuracy of the temperature sensor's detection results of the high-temperature flue gas delivered to the cooking cavity 204.

[0088] Furthermore, a control valve is also provided in the cold air flow channel 203. The control valve is used to control the amount of cold air delivered from the cold air flow channel 203 to the mixing flow channel 2053. That is, when the control valve is open, more cold air is delivered from the cold air flow channel 203 to the mixing flow channel 2053. When the control valve is open, less cold air is delivered from the cold air flow channel 203 to the mixing flow channel 2053. Outside cold air can flow through the cold air flow channel 203 to the mixing flow channel 2053 to mix with the high-temperature flue gas and then flow into the cooking cavity 204. When the amount of cold air is large, the temperature of the high-temperature flue gas delivered to the cooking cavity 204 is low. When the amount of cold air is small, the temperature of the high-temperature flue gas delivered to the cooking cavity 204 is high.

[0089] In this way, the control module can adjust the opening of the control valve based on the detection results transmitted by the temperature sensor and the cooking temperature required by the user, so as to regulate the temperature of the high-temperature flue gas delivered to the cooking cavity 204, improve the intelligence of the gas oven 1000, ensure the cooking effect, and thus improve the user experience.

[0090] In some embodiments, the combustion module 100 and / or the fan assembly 40 are both located on the outside of the oven body 200. This means that only the combustion module 100 is located on the outside of the oven body 200, only the fan assembly 40 is located on the outside of the oven body 200, or both the combustion module 100 and the fan assembly 40 are located on the outside of the oven body 200.

[0091] Specifically, the combustion module 100 can be connected to the outside of the oven body 200 by welding or connectors, which is a simple connection method. Preferably, the combustion module 100 can be installed on the rear side of the oven body 200 to avoid burns to the user caused by the high temperature generated during the operation of the combustion module 100, thus ensuring user safety. The fan assembly 40 is connected to the air inlet 50, which is formed in the housing 10 of the combustion module 100. That is, the fan assembly 40 is connected to the combustion module 100, so that the fan assembly 40 can deliver air into the combustion module 100 through the air inlet 50, ensuring the reliability of the operation of the combustion module 100. Furthermore, since both the fan assembly 40 and the combustion module 100 are located on the outside of the oven body 200, the effective volume of the cooking cavity 204 can be guaranteed, increasing the amount of food cooked and thus improving the user experience.

[0092] In addition, separating the fan assembly 40 from the combustion module 100 can prevent the high temperature generated when the combustion module 100 ignites the gas mixture from affecting the fan assembly 40, reduce the size of the fan assembly 40, ensure the reliability of the fan assembly 40 and extend its service life. Furthermore, the low-temperature air delivered by the fan assembly 40 can cool the walls inside the combustion module 100, improve the reliability of the gas oven 1000, and avoid using a high-temperature resistant fan assembly 40, thus saving on installation costs.

[0093] Meanwhile, the combustion module 100 and the fan assembly 40 can be installed on the same side of the oven. The oven body 200 has multiple oven sides, and the combustion module 100 and the fan assembly 40 can all be installed on the oven side, thereby increasing the effective volume of the cooking cavity 204. The combustion module 100 and the fan assembly 40 can be installed on the same side of the oven, that is, the combustion module 100 and the fan assembly 40 can all be set on the oven side located on the left side of the oven body 200, or the combustion module 100 and the fan assembly 40 can all be set on the oven side located on the right side of the oven body 200, or the combustion module 100 and the fan assembly 40 can all be set on the oven side located on the rear side of the oven body 200.

[0094] Preferably, the combustion module 100 and the fan assembly 40 can both be installed on the rear side of the oven body 200. This can prevent the user from being burned by the high temperature generated when the combustion module 100 is running, ensuring the safety of use. It can also shorten the pipes and other components required to connect the combustion module 100 and the fan assembly 40, reduce the installation cost, improve the installation compactness, and thus increase the volume of the gas oven 1000 and improve its lightweight.

[0095] In other embodiments, the fan assembly 40 is located below the combustion module 100.

[0096] Specifically, the fan assembly 40 is installed below the combustion module 100. That is, the fan assembly 40 delivers air to the air inlet 50 below the combustion module 100, and then enters the combustion module 100 through the air inlet 50. The air and gas mix and ignite above the combustion module 100, resulting in a higher temperature at the top of the combustion module 100. Installing the fan assembly 40 below the combustion module 100 can extend the service life of the fan assembly 40 and ensure the operational reliability of the fan assembly 40.

[0097] In some embodiments, the oven body 200 is provided with a high-temperature flue gas inlet 201 and a flue gas outlet 202 that are respectively connected to the cooking cavity 204. The high-temperature flue gas inlet 201 is connected to the high-temperature flue gas outlet, and the flue gas outlet 202 is connected to the outside of the oven body 200.

[0098] Specifically, such as Figures 1-2As shown, the oven body 200 has a cooking cavity 204, and a combustion module 100 is provided on the rear side of the oven body 200. The combustion module 100 is provided with a high-temperature flue gas outlet communicating with the cooking cavity 204 to deliver high-temperature flue gas into the cooking cavity 204, thereby heating the food in the cooking cavity 204. The oven body 200 is provided with a high-temperature flue gas inlet 201 and a flue gas outlet 202. The high-temperature flue gas inlet 201 is located on the rear side wall of the oven body 200, that is, the high-temperature flue gas inlet 201 is located close to the combustion module 100. The high-temperature flue gas inlet 201 is connected to the high-temperature flue gas outlet, which can shorten the distance between the high-temperature flue gas inlet 201 and the high-temperature flue gas outlet, reduce the energy loss generated during the transportation of high-temperature flue gas, and improve the energy efficiency of the gas oven 1000 during use.

[0099] Furthermore, the high-temperature flue gas generated by the combustion of the mixed gas in the combustion module 100 can be discharged from the combustion module 100 through the high-temperature flue gas outlet and can also flow to the high-temperature flue gas inlet 201, and then flow into the cooking cavity 204 through the high-temperature flue gas inlet 201, ensuring the reliability of the high-temperature flue gas delivery. In addition, the exhaust port 202 is connected to the outside of the oven body 200, so that the exhaust gas generated by cooking food can be discharged from the cooking cavity 204 through the exhaust port 202. The exhaust port 202 can be connected to the exhaust pipe to collect and filter the exhaust gas, thereby improving the environmental friendliness of the use.

[0100] In some embodiments, a rectifier plate 205 is provided in the cooking cavity 204. The rectifier plate 205 is used to define a mixing channel 2053. The mixing channel 2053 is connected to the high-temperature flue gas inlet 201. The mixing channel 2053 forms a high-temperature flue gas connection port 206, which is connected to the cooking cavity 204.

[0101] Specifically, the oven body 200 is provided with a high-temperature flue gas inlet 201 that communicates with the cooking cavity 204, so that the combustion module 100 can deliver high-temperature flue gas into the cooking cavity 204 through the high-temperature flue gas inlet 201, and as... Figures 1-4 As shown, a rectifier plate 205 is provided inside the cooking cavity 204. The rectifier plate 205 can be connected to the inner wall of the cooking cavity 204 by welding or connecting parts, which is simple to install. The rectifier plate 205 can define a mixing channel 2053 between itself and the inner wall of the cooking cavity 204. The mixing channel 2053 is connected to the high-temperature flue gas inlet 201, so that the high-temperature flue gas entering the cooking cavity 204 through the high-temperature flue gas inlet 201 can flow along the mixing channel 2053.

[0102] Furthermore, such as Figure 2As shown, the mixing channel 2053 also has a high-temperature flue gas connection port 206, which can be connected to the cooking cavity 204. This allows the high-temperature flue gas flowing into the mixing channel 2053 to enter the cooking cavity 204 through the high-temperature flue gas connection port 206. Consequently, when the high-temperature flue gas impacts the rectifier plate 205, its speed and direction will change, thereby enhancing the disturbance and mixing of the high-temperature flue gas. This allows the high-temperature flue gas to flow out more evenly from the high-temperature flue gas connection port 206 of the rectifier plate 205 and then be delivered to the food surface to heat the food.

[0103] In addition, the rectifier plate 205 can be configured as a plate-like structure connected to the inner wall of the cooking cavity 204. In actual installation, a pressed structure can also be directly installed on the inner wall of the cooking cavity 204, so that high-temperature flue gas can flow from the side and bottom of the cooking cavity 204 into the cooking cavity 204, thereby improving the cooking effect.

[0104] In some embodiments, the oven body 200 is further provided with a cold air inlet 2031, which is connected to the mixing channel 2053.

[0105] Specifically, the oven body 200 may also be provided with a cold air inlet 2031. The cold air inlet 2031 may be located above the oven body 200, so that the cold air inlet 2031 can be connected to the mixing channel 2053, thereby allowing cold air from the outside of the oven body 200 to enter the mixing channel 2053 through the cold air inlet 2031. Alternatively, the cold air inlet 2031 may be located at the rear of the oven body 200, so that the cold air inlet 2031 can be connected to the mixing channel 2053 through the high-temperature flue gas inlet 201, thereby allowing cold air from the outside of the oven body 200 to enter the high-temperature flue gas inlet 201 through the cold air inlet 2031, and then enter the mixing channel 2053 through the high-temperature flue gas inlet 201.

[0106] Furthermore, the temperature of the high-temperature flue gas after the combustion of the mixed gas is relatively high, typically reaching 800℃-1000℃. If this high-temperature flue gas is directly introduced into the cooking chamber 204 to heat the food, it will cause the food to char. By introducing cold air into the mixing channel 2053 through the cold air inlet 2031, the cold air and the high-temperature flue gas can be mixed in the mixing channel 2053, thereby appropriately cooling the high-temperature flue gas so that its temperature drops below 400℃ before being delivered into the cooking chamber 204, ensuring the food cooking effect.

[0107] In some embodiments, a cold air inlet 2031 is connected to the top of a mixing channel 2053, and a high-temperature flue gas inlet 206 is formed at the bottom of the mixing channel 2053.

[0108] Specifically, the oven body 200 is provided with a cold air inlet 2031, which is connected to the mixing channel 2053 and is connected to the top of the mixing channel 2053. That is, cold air flows through the cold air inlet 2031 to the top of the mixing channel 2053 for circulation within the mixing channel 2053. A high-temperature flue gas connection port 206 is formed at the bottom of the mixing channel 2053, allowing high-temperature flue gas to flow into the cooking cavity 204 through the high-temperature flue gas connection port 206. Furthermore, the cold air can mix with the high-temperature flue gas in the mixing channel 2053. The cold air inlet 2031 is connected to the top of the mixing channel 2053, so that the distance between the mixing point of the cold air and the high-temperature flue gas and the high-temperature flue gas connection port 206 is relatively long. This allows the cold air to mix fully with the high-temperature flue gas in the mixing channel 2053, so that the high-temperature flue gas is sufficiently cooled. Then, the high-temperature flue gas is circulated into the cooking chamber 204 through the high-temperature flue gas connection port 206 to cook the food, ensuring the reliability of cooling and improving the cooking effect.

[0109] In some embodiments, the rectifier plate 205 includes a main plate portion 2051 and at least one connecting flange 2052. The main plate portion 2051 is connected to the inner wall of the cooking cavity 204 through the connecting flange 2052. The main plate portion 2051 is distributed opposite to the high-temperature flue gas outlet. The main plate portion 2051 is spaced apart from the inner wall of the cooking cavity 204 and together define a mixing channel 2053.

[0110] Specifically, the baffle 205 is installed on the inner wall of the cooking cavity 204, and as... Figures 2-3 As shown, the rectifier plate 205 is provided with a main board part 2051 and a connecting flange 2052. The connecting flange 2052 is connected to the side edge of the main board part 2051 and can be connected to the main board part 2051 by welding or integral molding. The end of the connecting flange 2052 away from the main board part 2051 can also be connected to the inner wall of the cooking cavity 204 by welding or connectors, so that the main board part 2051 can be fixedly installed on the inner wall of the cooking cavity 204.

[0111] Furthermore, when the rectifier plate 205 is installed in the cooking cavity 204, the main plate portion 2051 can be distributed directly opposite the high-temperature flue gas outlet, so that the high-temperature flue gas discharged from the high-temperature flue gas outlet can collide with the main plate portion 2051, thereby changing the speed and direction of the high-temperature flue gas to enhance the disturbance and mixing of the high-temperature flue gas. The main plate portion 2051 is spaced apart from the inner wall of the cooking cavity 204 and together defines the mixing channel 2053, so that the high-temperature flue gas that has been sufficiently disturbed and mixed in the main plate portion 2051 can flow along the mixing channel 2053 to the high-temperature flue gas connection port 206, and then flow into the cooking cavity 204 to heat the food and improve the cooking effect.

[0112] In some embodiments, the exhaust port 202 is lower than the high-temperature flue gas inlet 201.

[0113] Specifically, the exhaust vent 202 is externally connected to the oven body 200, allowing exhaust gases generated during cooking to be discharged from the cooking cavity 204 through the exhaust vent 202. The oven body 200 is also equipped with a high-temperature flue gas inlet 201, through which the combustion module 100 supplies high-temperature flue gas into the cooking cavity 204. Figure 1 As shown, the exhaust port 202 is set lower than the high-temperature flue gas inlet 201. The density of the high-temperature flue gas is lower than the density of the cold air in the cooking chamber 204. This allows the high-temperature flue gas to enter the cooking chamber 204 through the high-temperature flue gas connection port 206 of the mixing channel 2053 and flow upwards in the cooking chamber 204. This causes the cold air to flow downwards to the exhaust port 202 at the bottom of the cooking chamber 204 to be discharged from the cooking chamber 204. As a result, the high-temperature flue gas can gradually fill the entire cooking chamber 204, increasing the heating speed of the cooking chamber 204 and improving the user experience.

[0114] In some embodiments, the high-temperature flue gas outlet is located at the top of the combustion module 100, and the air inlet 50 is located at the bottom of the combustion module 100, wherein the fan assembly 40 is installed below the combustion module 100.

[0115] Specifically, the combustion module 100 is provided with a high-temperature flue gas outlet, and the high-temperature flue gas outlet is located at the top of the combustion module 100, that is, the high-temperature flue gas can flow from the top of the combustion module 100 to the high-temperature flue gas outlet, and then flow into the cooking cavity 204 through the high-temperature flue gas inlet 201. The combustion module 100 is provided with an air inlet 50, which is located at the bottom of the combustion module 100, so that air can enter the combustion module 100 from below.

[0116] Furthermore, the fan assembly 40 is installed below the combustion module 100. That is, the fan assembly 40 delivers air to the air inlet 50 below the combustion module 100, and then enters the combustion module 100 through the air inlet 50. The air and gas mix and ignite above the combustion module 100, resulting in a higher temperature at the top of the combustion module 100. Installing the fan assembly 40 below the combustion module 100 can extend the service life of the fan assembly 40 and ensure the operational reliability of the fan assembly 40.

[0117] In addition, a burner 20 is provided inside the combustion module 100. The mixed gas is ignited at the burner 20. The high-temperature flue gas generated after ignition can flow into the cooking chamber 204 through the high-temperature flue gas inlet 201. The high-temperature flue gas inlet 201 is set higher than the burner 20 and must be higher than the flame height of the burner 20, so as to prevent the flame from flowing into the cooking chamber 204 and ensure the reliability of the burner 20.

[0118] In this embodiment, the distance between the high-temperature flue gas inlet 201 and the burner 20 can be set to H, and it satisfies: 65mm≤H, that is, the distance H between the high-temperature flue gas inlet 201 and the burner 20 can be set to greater than or equal to 65mm, such as 65mm, 66mm, 67mm, 68mm, 69mm, or 70mm, etc., to ensure the reliability of use and improve the flexibility of setting.

[0119] In some embodiments, the combustion module 100 includes a housing 10, within which are formed an air cavity 101, a first mounting cavity 102, and a second mounting cavity 103. The first mounting cavity 102 communicates with the air cavity 101, and the second mounting cavity 103 communicates with the air cavity 101 and a combustion chamber 104 located above the housing 10. An air inlet 50 communicates with the air cavity 101, and a high-temperature flue gas outlet communicates with the combustion chamber 104.

[0120] Specifically, a combustion module 100 is provided on the outside of the oven body 200. The combustion module 100 can supply high-temperature air required for cooking into the cooking cavity 204. The combustion module 100 is provided with a housing 10. The combustion module 100 is connected to the outside of the oven body 200 through the housing 10. It can be installed conveniently by welding or connecting parts. An air cavity 101, a first mounting cavity 102 and a second mounting cavity 103 are formed inside the housing 10. An air inlet 50 is formed in the housing 10 of the combustion module 100 and is connected to the air cavity 101. That is, the fan assembly 40 can supply air into the air cavity 101 through the air inlet 50.

[0121] Furthermore, the air cavity 101 is connected to the first mounting cavity 102, allowing air in the air cavity 101 to flow into the first mounting cavity 102. The air cavity 101 is also connected to the second mounting cavity 103, allowing air in the air cavity 101 to flow into the second mounting cavity 103. At the same time, the second mounting cavity 103 is also connected to the combustion cavity 104 located above the housing 10, allowing air in the second mounting cavity 103 to flow into the combustion cavity 104. In other words, a portion of the air in the air cavity 101 can be sent to the first mounting cavity 102, and another portion of the air can be sent to the second mounting cavity 103.

[0122] The burner 20 has an inlet connected to the first mounting cavity 102 and an outlet connected to the combustion cavity 104. The gas injection assembly 30 has a nozzle opposite to the inlet of the burner 20. At least a portion of the first mounting cavity 102 is located between the inlet and the nozzle of the burner 20.

[0123] Specifically, after the gas is sent to the gas injection assembly 30, at least a portion of the gas is ejected from the nozzle and sent to the inlet of the burner 20. When the gas is injected into the inlet of the burner 20, some air in the first mounting chamber 102 is also introduced into the inlet of the burner 20 to achieve primary gas replenishment. This allows for the premixing of gas and air, and the gas-air mixture is sent to the outlet of the burner 20 so that the gas can burn completely after ignition. The air sent to the second mounting chamber 103 can be introduced into the combustion chamber 104 after passing through the second mounting chamber 103 to achieve secondary gas replenishment, thereby achieving complete combustion of the gas, improving energy efficiency, saving energy and protecting the environment. It can also cool the flue gas generated by the combustion of gas, preventing the flue gas temperature from being too high and affecting the cooking effect and the taste of the cooked food.

[0124] In order to ensure that air is evenly introduced into the first mounting cavity 102 and to control the air flow rate into the first mounting cavity 102, a flow equalization plate can be set between the first mounting cavity 102 and the air cavity 101.

[0125] In some embodiments, a primary flow equalization plate is provided between the first mounting cavity 102 and the air cavity 101, and the primary flow equalization plate is provided with a plurality of flow equalization holes.

[0126] Specifically, the air cavity 101 is connected to the first mounting cavity 102, and the fan assembly 40 can supply air into the first mounting cavity 102 through the air cavity 101, such as... Figure 11 As shown, a primary flow equalization plate is provided between the first mounting cavity 102 and the air cavity 101, and the primary flow equalization plate is provided with multiple flow equalization holes. The multiple flow equalization holes are all arranged through the primary flow equalization plate, so that the air in the air cavity 101 can flow into the first mounting cavity 102 through the multiple flow equalization holes. The multiple flow equalization holes can be arranged in a grid-like distribution, so that the primary flow equalization plate can control the air in the air cavity 101 to enter the first mounting cavity 102 more evenly. The primary flow equalization plate can also block the air, avoiding problems such as flame lift-off caused by excessive primary air supply, thereby achieving stable combustion of the combustion module 100 and improving the flue gas temperature control capability of the combustion module 100.

[0127] Alternatively, a flow equalization plate can be provided in the second mounting cavity 103 to ensure that the air in the air cavity 101 can be evenly introduced into the combustion cavity 104 through the second mounting cavity 103. The flow equalization plate in the second mounting cavity 103 can be provided in, but is not limited to, the following embodiments:

[0128] Furthermore, a first primary flow equalization plate 111 is provided between the first primary air chamber 1021 and the air cavity 101. The first primary flow equalization plate 111 is provided with a plurality of first flow equalization holes 1023, which are arranged in a grid-like manner. A second primary flow equalization plate 112 is provided between the second primary air chamber 1022 and the air cavity 101. The second primary flow equalization plate 112 is provided with a plurality of second flow equalization holes 1024, which are arranged in a grid-like manner. By setting the first primary flow equalization plate 111 and the second primary flow equalization plate 112, the first primary flow equalization plate 111 can be used to control the air in the air cavity 101 to be introduced into the first primary air chamber 1021 more evenly, and the second primary flow equalization plate 112 can be used to control the air in the air cavity 101 to be introduced into the second primary air chamber 1022 more evenly. Moreover, the first primary flow equalization plate 111 and the second primary flow equalization plate 112 can also have the function of blocking air, which can avoid the problem of flame lift-off caused by excessive primary air supply, thereby achieving stable combustion of the combustion module 100 and improving the flue gas temperature control capability of the combustion module 100.

[0129] In some embodiments, a first secondary flow equalization plate 121 is provided between the second mounting cavity 103 and the air cavity 101, and the first secondary flow equalization plate 121 is provided with a plurality of first vent holes 1033.

[0130] Specifically, the air cavity 101 is connected to the second mounting cavity 103, and the fan assembly 40 can supply air into the second mounting cavity 103 through the air cavity 101, such as... Figure 11 As shown, a first and second flow equalization plate 121 is provided between the second mounting cavity 103 and the air cavity 101, and the first and second flow equalization plate 121 is provided with a plurality of first vent holes 1033. The plurality of first vent holes 1033 are all provided through the first and second flow equalization plate 121, so that the air in the air cavity 101 can flow into the second mounting cavity 103 through the plurality of first vent holes 1033. The plurality of first vent holes 1033 can be arranged in a grid shape.

[0131] Furthermore, some of the air in the air cavity 101 can be introduced into the second mounting cavity 103 through multiple first vent holes 1033. This can achieve the goal of sending air to the combustion cavity 104 while avoiding excessive air volume entering the combustion cavity 104, so as to control the flue gas temperature in the combustion cavity 104. It can also achieve uniform air delivery to the combustion cavity 104, thereby improving the uniformity of air entering various parts of the second mounting cavity 103 and achieving uniform adjustment of the flue gas temperature in various parts of the combustion cavity 104.

[0132] Optionally, at least a portion of the burner 20 in this invention can be disposed within the second mounting cavity 103, so that the burner 20 can be cooled when the secondary gas supply passes through the second mounting cavity 103.

[0133] In some embodiments, a second secondary flow equalization plate 122 is provided between the second mounting cavity 103 and the combustion cavity 104, and the second secondary flow equalization plate 122 is provided with a plurality of second vent holes 1034.

[0134] Specifically, the second mounting cavity 103 is connected to the combustion cavity 104, and the second mounting cavity 103 can supply air into the combustion cavity 104, such as... Figure 9 As shown, a second secondary flow equalization plate 122 is provided between the second mounting cavity 103 and the combustion cavity 104, and the second secondary flow equalization plate 122 is provided with a plurality of second vent holes 1034. The plurality of second vent holes 1034 are all provided through the second secondary flow equalization plate 122, so that the air in the second mounting cavity 103 can flow into the combustion cavity 104 through the plurality of second vent holes 1034. The plurality of second vent holes 1034 can be arranged in a grid shape.

[0135] Furthermore, air from the second mounting cavity 103 is introduced into the combustion cavity 104 through multiple second vent holes 1034. This ensures air is supplied to the combustion cavity 104 while preventing excessive air volume, thus controlling the flue gas temperature within the combustion cavity 104. It also ensures uniform air distribution within the combustion cavity 104, improving the uniformity of air supply throughout the second mounting cavity 103 and achieving uniform temperature regulation of the flue gas throughout the combustion cavity 104. Additionally, it prevents insufficient secondary air supply, which could lead to excessively high flue gas temperatures.

[0136] Optionally, such as Figures 10-11 As shown, at least a portion of the burner 20 is disposed in the second mounting cavity 103, the second secondary flow equalization plate 122 is provided with a mating hole, the outlet of the burner 20 is opposite to the mating hole, and a plurality of second vent holes 1034 are distributed around the mating hole. Further, the plurality of second vent holes 1034 are distributed on opposite sides of the mating hole along the thickness direction of the burner 20, i.e., as shown... Figure 6 The two opposite sides in the front-to-back direction shown can improve the uniformity of secondary air supply, achieve uniform combustion of fuel gas, improve energy efficiency, and save energy and protect the environment.

[0137] The burner 20 can be configured to pass through the mating hole, and the outlet of the burner 20 is spaced apart from the surface of the second and secondary flow equalization plate 122 by a predetermined distance.

[0138] Furthermore, a first and second flow equalization plate 121 is provided between the second mounting cavity 103 and the air cavity 101, and the first and second flow equalization plate 121 has a plurality of first vent holes 1033 arranged in a grid pattern. A second and second flow equalization plate 122 is provided between the second mounting cavity 103 and the combustion cavity 104, and the second and second flow equalization plate 122 has a plurality of second vent holes 1034 arranged in a grid pattern. By combining the first and second flow equalization plates 121 and 122, the amount of air entering the combustion cavity 104 through the second mounting cavity 103 can be controlled, which facilitates the stable supply of secondary air to the combustion cavity 104, improves the combustion stability of the burner 20, achieves complete combustion of the gas, and enables uniform adjustment of the flue gas in all parts of the burner 20.

[0139] Optionally, at least one of the following: the number of holes, the area of ​​a single hole, or the total area of ​​the first vent 1033 and the second vent 1034, can be set to be the same or different.

[0140] In addition, a third secondary flow equalization plate is provided inside the second mounting cavity 103. The third secondary flow equalization plate is located between the inlet and outlet of the second mounting cavity 103. A first secondary flow equalization plate 121 can be provided at the inlet of the second mounting cavity 103, that is, between the second mounting cavity 103 and the air cavity 101; and / or, a second secondary flow equalization plate 122 can be provided at the outlet of the second mounting cavity 103, that is, between the second mounting cavity 103 and the combustion cavity 104.

[0141] In some embodiments, the burner 20 includes: a first burner 21 and a second burner 22, the first burner 21 having a first inlet 2101 and a first outlet 2102, the second burner 22 having a second inlet 2201 and a second outlet 2202, the second burner 22 and the first burner 21 being distributed in a left-right direction, and the first inlet 2101 and the second inlet 2201 being opposite to each other in a left-right direction.

[0142] Specifically, the burner 20 has inlets including a first inlet 2101 and a second inlet 2201, and outlets including a first outlet 2102 and a second outlet 2202. Gas can enter the first burner 21 through the first inlet 2101 or the second burner 22 through the second inlet 2201, and after passing through the first burner 21, it exits from the first outlet 2102, and after passing through the second burner 22, it exits from the second outlet 2202. This increases the flow rate into the burner 20 and improves its operating efficiency, enabling faster and more efficient heating or cooking.

[0143] In addition, setting up multiple burners can optimize the air-to-gas ratio. Compared to increasing the gas supply by increasing the burner volume, it can avoid combustion instability caused by uneven mixing of gas and air, and avoid the problem of incomplete combustion caused by excessive gas flow into a single burner.

[0144] In some embodiments, the second mounting cavity 103 includes a first secondary air chamber 1031 and a second secondary air chamber 1032 distributed in a left-right direction. The first mounting cavity 102 can be disposed between the first secondary air chamber 1031 and the second secondary air chamber 1032 to improve the space utilization of the combustion module 100 and to ensure stable airflow into the first mounting cavity 102, the first secondary air chamber 1031, and the second secondary air chamber 1032.

[0145] Additionally, at least a portion of the first burner 21 can be located in the first secondary air chamber 1031, and at least a portion of the second burner 22 can be located in the second secondary air chamber 1032. This further improves space utilization and facilitates heat exchange between the air in the first secondary air chamber 1031 and the first burner 21, and between the air in the second secondary air chamber 1032 and the second burner 22, thereby improving the stability of the combustion module 100, achieving complete combustion of the gas, and improving energy efficiency.

[0146] In some embodiments, the gas injection assembly 30 has a first nozzle 301 opposite to the first inlet 2101 and a second nozzle 302 opposite to the second inlet 2201, i.e. Figures 10-11 As shown, the gas injection assembly 30 is provided with a first nozzle 301 and a second nozzle 302. The first nozzle 301 is disposed opposite to the first inlet 2101, and the second nozzle 302 is disposed opposite to the second inlet 2201. The first mounting cavity 102 includes a first primary air chamber 1021 and a second primary air chamber 1022. At least a portion of the first primary air chamber 1021 is disposed between the first nozzle 301 and the first inlet 2101, and at least a portion of the second primary air chamber 1022 is disposed between the second nozzle 302 and the second inlet 2201. The first primary air chamber 1021 is connected to the air chamber 101, and the second primary air chamber 1022 is connected to the air chamber 101.

[0147] Specifically, when the burner 20 is operating, the gas injection assembly 30 can inject gas into the first inlet 2101 through the first nozzle 301. Air in the first primary air chamber 1021 can be introduced into the first burner 21 along with the gas and mixed within the first burner 21. This optimizes the proportion and uniformity of gas and air distribution within the first burner 21, thereby achieving uniform combustion of the gas after it passes through the first burner 21. Additionally, the gas injection assembly 30 can inject gas into the second inlet 2201 through the second nozzle 302. Air in the second primary air chamber 1022 can be introduced into the second burner 22 along with the gas and mixed within the second burner 22. This optimizes the proportion and uniformity of gas and air distribution within the second burner 22, thereby achieving uniform combustion of the gas after it passes through the second burner 22.

[0148] The gas injection assembly 30 can be disposed in the first mounting cavity 102, and the first primary air chamber 1021 and the second primary air chamber 1022 are respectively disposed on opposite sides of the gas injection assembly 30.

[0149] Furthermore, the gas can be introduced into the first burner 21 through the first inlet 2101, or into the second burner 22 through the second inlet 2201, and then exited from the first outlet 2102 after passing through the first burner 21, and from the second outlet 2202 after passing through the second burner 22. This increases the flow rate into the burner 20 and improves its operating efficiency, enabling faster and more efficient heating or cooking. In addition, setting multiple burners optimizes the air-to-gas ratio. Compared to increasing the gas supply by increasing the burner volume, this avoids unstable combustion caused by uneven gas-air mixing and prevents incomplete combustion due to excessive gas flow into a single burner.

[0150] In some embodiments, such as Figure 10 and Figure 11 As shown, the air cavity 101 is located at the lower part of the housing 10, and the first mounting cavity 102 and the second mounting cavity 103 are located above the air cavity 101. That is, the air delivered by the fan assembly 40 flows upward into the air cavity 101 and is then delivered to the first mounting cavity 102 and the second mounting cavity 103 through the air cavity 101. The lower parts of the first mounting cavity 102 and the second mounting cavity 103 are arranged side by side, so that the air in the air cavity 101 can flow towards the first mounting cavity 102 and the second mounting cavity 103 respectively, so that the first mounting cavity 102 and the second mounting cavity 103 can be simultaneously supplied with gas, ensuring the reliability of gas combustion and simplifying the structure, making it easier for the airflow to be delivered into the first mounting cavity 102 and the second mounting cavity 103 through the air cavity 101.

[0151] In other embodiments, the gas injection assembly 30 is disposed in the first mounting cavity 102, which can improve the space utilization of the combustion module 100, reduce the volume of the combustion module 100, thereby increasing the volume of the cooking cavity 204, and facilitate the gas injection assembly 30 to inject gas into the inlet of the burner 20, which facilitates the mixing of gas and air in the burner 20, and improves the combustion efficiency and stability of the gas.

[0152] In some embodiments, the outlet of the fan assembly 40 is opposite to the first mounting cavity 102, thereby allowing the air output from the fan assembly 40 to flow in a straight line into the first mounting cavity 102, which means that the fan assembly 40 delivers air into the first mounting cavity 102, reducing the wind resistance during air flow, thereby reducing operating energy consumption and improving energy utilization.

[0153] In addition, the outlet of the fan assembly 40 is connected to the first side wall of the air cavity 101, and the first mounting cavity 102 is connected to the second side wall of the air cavity 101. The first side wall and the second side wall are distributed opposite to each other, that is, the outlet of the fan assembly 40 can enter the air cavity 101 from the first side wall of the air cavity 101 and flow from the second side wall of the air cavity 101 to the first mounting cavity 102. This allows air to be stably introduced into the first mounting cavity 102 and the second mounting cavity 103, and facilitates the fan assembly 40 to control the air flow rate introduced into the first mounting cavity 102 and the second mounting cavity 103, thereby improving the reliability of air supply.

[0154] In other embodiments, the fan assembly 40 includes a centrifugal fan, meaning the fan assembly 40 may be equipped with a centrifugal fan. The centrifugal fan has high power and a large flow rate. Connecting the fan assembly 40 with the centrifugal fan to the combustion module 100 via the air inlet 50 and supplying air into the combustion module 100 can increase the airflow into the combustion module 100, thereby improving the operational stability of the combustion module 100. Furthermore, this application allows adjustment of the distribution size of the flow equalization holes in the first primary flow equalization plate 111 and the second primary flow equalization plate 112, thereby ensuring the uniformity of air delivery from the centrifugal fan to the first primary air chamber 1021 and the second primary air chamber 1022, thus improving the cooking effect of the gas oven 1000.
