[0047] The following is for reference. Figures 1-10 The gas oven 1000 according to the present invention can ensure the effective volume of the cooking cavity 204, improve the user experience, reduce the setup cost, extend the service life of the fan assembly 40, and ensure the operational reliability of the fan assembly 40, thereby improving the reliability of the gas oven 1000.

[0048] like Figures 1-10 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.

[0049] 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 located on the outside of the oven body 200 and is used to supply air to the air inlet 50.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Furthermore, the gas oven 1000 is also equipped with a fan assembly 40, which is also located on the outside of the oven body 200. The fan assembly 40 can be connected to the outer wall of the oven body 200 by welding or connecting parts. Preferably, the fan assembly 40 can be installed on the rear side of the oven body 200, that is, the fan assembly 40 is set close to the combustion module 100. The fan assembly 40 is used to supply air to the combustion module 100. Setting the fan assembly 40 close to the combustion module 100 can shorten the length of the pipe set for supplying air to the fan assembly 40, thereby reducing the installation cost and reducing the energy consumed in the air supply process, thus reducing energy consumption.

[0055] In addition, 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 combustion module 100. Both the fan assembly 40 and the combustion module 100 are located on the outside of the oven body 200, which can ensure the effective volume of the cooking cavity 204, increase the amount of food cooked, and thus improve the user experience.

[0056] Furthermore, separating the fan assembly 40 from the combustion module 100 avoids the high temperature generated when the combustion module 100 ignites the gas mixture from affecting the fan assembly 40. This reduces the size of the fan assembly 40, ensures its reliability, and extends its service life. Additionally, the low-temperature air delivered by the fan assembly 40 can cool the walls inside the combustion module 100, improving the reliability of the gas oven 1000. It also avoids the need to use a high-temperature resistant fan assembly 40, saving on installation costs.

[0057] According to the gas oven 1000 of this utility model embodiment, the combustion module 100 and the fan assembly 40 are both located on the outside of the oven body 200, which can increase the effective volume of the cooking cavity 204 and improve the user experience. Moreover, the fan assembly 40 is set separately from the combustion module 100. The fan assembly 40 can supply air into the combustion module 100 through the air inlet 50, which can avoid the fan assembly 40 from contacting high-temperature gas, reduce the installation cost of the fan assembly 40, extend the service life of the fan assembly 40, and ensure the operational reliability of the fan assembly 40, thereby improving the reliability of the gas oven 1000.

[0058] In some embodiments, the fan assembly 40 is mounted below the combustion module 100.

[0059] 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.

[0060] In some embodiments, the air inlet 50 is configured to open downward at the bottom of the combustion module 100, and the fan assembly 40 has an upward-opening air delivery port 401 directly opposite the bottom of the air inlet 50.

[0061] Specifically, the fan assembly 40 is installed below the combustion module 100 and can supply air into the combustion module 100 through the air inlet 50, such as... Figure 1 As shown, the air inlet 50 is located at the bottom of the combustion module 100 and is open downwards. The fan assembly 40 is installed below the combustion module 100, that is, the air inlet 50 is open towards the fan assembly 40. The fan assembly 40 is provided with an air delivery port 401, which is located at the top of the fan assembly 40 and is open upwards. That is, the air delivery port 401 is open towards the air inlet 50 of the combustion module 100, so that the air delivery port 401 is directly connected to the bottom of the air inlet 50.

[0062] Furthermore, when the fan assembly 40 is running, it can deliver air to the air inlet 401, and then deliver it to the air inlet 50 through the air inlet 401 to enter the combustion module 100. This allows the air to flow from below into the combustion module 100, where it mixes with the gas and is ignited. The high-temperature flue gas after ignition has a low density and can flow upwards, saving power and ensuring the reliability of the fan assembly 40. This also prevents the high-temperature flue gas from damaging the fan assembly 40 and extends its service life.

[0063] In some embodiments, the outer surface of the oven body 200 includes an oven top surface 60, an oven bottom surface 70, and a plurality of oven side surfaces 80 connected sequentially along the circumference of the oven body 200, with the combustion module 100 and / or the fan assembly 40 mounted on the oven side surfaces 80.

[0064] Specifically, the oven body 200 is located on the outermost side of the gas oven 1000, and the oven body 200 can be rectangular or cylindrical, etc. A cooking cavity 204 is formed inside the oven body 200 for placing food and for cooking the food within the cooking cavity 204, such as... Figure 1 and Figure 4 As shown, the oven body 200 is rectangular and has an oven top surface 60, an oven bottom surface 70, and oven sides 80. The oven top surface 60 is located on the top of the gas oven 1000, the oven bottom surface 70 is located on the bottom of the gas oven 1000, and there are multiple oven sides 80, which are connected sequentially along the circumference of the oven body 200 so that the oven top surface 60, the oven bottom surface 70, and the multiple oven sides 80 can together form a complete oven body 200.

[0065] Furthermore, the upper parts of the multiple oven sides 80 are all connected to the top surface 60 of the oven, and the lower parts of the multiple oven sides 80 are all connected to the bottom surface 70 of the oven. The multiple oven sides 80 can be set to four, and the four oven sides 80 can be located on the front and rear sides and the left and right sides of the oven body 200, respectively. The combustion module 100 and / or the fan assembly 40 are installed on the oven sides 80. It is possible to install only the combustion module 100 on the oven sides 80, or only the fan assembly 40 on the oven sides 80, or both the combustion module 100 and the fan assembly 40 on the oven sides 80, thereby increasing the effective volume of the cooking cavity 204 and ensuring the user experience.

[0066] In some embodiments, the combustion module 100 and the fan assembly 40 are mounted on the same oven side 80.

[0067] Specifically, the oven body 200 is provided with multiple oven sides 80. The combustion module 100 and the fan assembly 40 can both be installed on the oven side 80, 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 oven side 80, that is, the combustion module 100 and the fan assembly 40 can both be set on the oven side 80 located on the left side of the oven body 200, or the combustion module 100 and the fan assembly 40 can both be set on the oven side 80 located on the right side of the oven body 200, or the combustion module 100 and the fan assembly 40 can both be set on the oven side 80 located on the rear side of the oven body 200.

[0068] Furthermore, in this embodiment, both the combustion module 100 and the fan assembly 40 are located on the oven side 80 behind the oven body 200, allowing the fan assembly 40 to be positioned close to the combustion module 100. The fan assembly 40 is used to supply air to the combustion module 100. Positioning the fan assembly 40 close to the combustion module 100 shortens the length of the pipe used to supply air, thereby reducing installation costs and energy consumption during air supply. Additionally, positioning both the combustion module 100 and the fan assembly 40 on the oven side 80 behind the oven body 200 prevents the combustion module 100 from scalding the user, improving safety.

[0069] In some embodiments, the air inlet 50 is located at the bottom of the combustion module 100, and the high-temperature flue gas outlet is located at the top of the combustion module 100.

[0070] Specifically, the fan assembly 40 can deliver air upward through the air inlet 401. The air inlet 401 and the air inlet 50 allow air to enter the combustion module 100 through the air inlet 50. The air inlet 50 is located at the bottom of the combustion module 100, allowing air to be delivered from below to above the combustion module 100 and mixed with the gas inside the combustion module 100. The mixed gas can be ignited by the burner 20 to produce high-temperature flue gas. The high-temperature flue gas has a low density and can be delivered upward naturally. The high-temperature flue gas outlet is located at the top of the combustion module 100, which facilitates the entry of the high-temperature flue gas into the cooking chamber 204, ensuring reliable delivery and saving energy consumption, thus improving energy efficiency.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] In some embodiments, there are multiple high-temperature flue gas outlets and multiple high-temperature flue gas inlets 201, and the multiple high-temperature flue gas outlets are connected to the multiple high-temperature flue gas inlets 201 in a one-to-one correspondence.

[0075] Specifically, the combustion module 100 is provided with a high-temperature flue gas outlet, and the oven body 200 is provided with a high-temperature flue gas inlet 201 that communicates with the cooking cavity 204. The high-temperature flue gas inlet 201 is connected to the high-temperature flue gas outlet, so that the combustion module 100 can deliver high-temperature flue gas to the high-temperature flue gas inlet 201 through the high-temperature flue gas outlet. The high-temperature flue gas outlet can be set to multiple, that is, two, three or four, etc. The high-temperature flue gas inlet 201 can also be set to multiple, that is, two, three or four, etc.

[0076] Furthermore, multiple high-temperature flue gas outlets are connected one-to-one with multiple high-temperature flue gas inlets 201, meaning that each high-temperature flue gas outlet is connected to a corresponding high-temperature flue gas inlet 201. This allows the combustion module 100 to deliver high-temperature flue gas into the cooking chamber 204 through multiple high-temperature flue gas outlets and multiple high-temperature flue gas inlets 201, increasing the delivery speed and thus increasing the cooking speed. In addition, the multiple high-temperature flue gas inlets 201 are spaced apart, which can expand the heating range to ensure the cooking effect on all parts of the food and improve the user experience.

[0077] In some embodiments, an rectifier channel 2053 is also formed in the oven body 200. The rectifier channel 2053 is connected between the high-temperature flue gas outlet and the cooking cavity 204, and the rectifier channel 2053 is adapted to guide the high-temperature flue gas from top to bottom into the cooking cavity 204.

[0078] Specifically, such 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 rectifier flow channel 2053 between itself and the inner wall of the cooking cavity 204. The rectifier flow channel 2053 connects the high-temperature flue gas outlet and the cooking cavity 204, so that the high-temperature flue gas entering the cooking cavity 204 through the high-temperature flue gas outlet can circulate along the rectifier flow channel 2053.

[0079] Furthermore, such as Figure 2 As shown, the rectifier 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 rectifier 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.

[0080] 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.

[0081] In some embodiments, the oven body 200 is further provided with a cold air inlet 203, which is connected to a high-temperature flue gas outlet.

[0082] Specifically, the oven body 200 may also be provided with a cold air inlet 203, such as Figure 1 As shown, the cold air inlet 203 can be located above the oven body 200, allowing the cold air inlet 203 to connect with the high-temperature flue gas outlet. This enables cold air from outside the oven body 200 to enter the high-temperature flue gas outlet through the cold air inlet 203. It can also be used as... Figure 2 As shown, the cold air inlet 203 is located on the rear side of the oven body 200, so that the cold air inlet 203 can be connected to the high temperature flue gas inlet 201 through the high temperature flue gas outlet, thereby allowing the cold air outside the oven body 200 to enter the high temperature flue gas outlet through the cold air inlet 203, and then enter the rectifier flow channel 2053 through the high temperature flue gas outlet.

[0083] 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 rectifier channel 2053 through the cold air inlet 203, the cold air and the high-temperature flue gas can be mixed in the rectifier 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.

[0084] Specifically, the oven body 200 may also be provided with a cold air inlet 203, such as Figure 1 As shown, the cold air inlet 203 can be located above the oven body 200, allowing the cold air inlet 203 to communicate with the rectifier channel 2053. This allows cold air from outside the oven body 200 to enter the rectifier channel 2053 through the cold air inlet 203. It can also... Figure 2 As shown, the cold air inlet 203 is located at the rear of the oven body 200, so that the cold air inlet 203 can be connected to the rectifier channel 2053 through the high temperature flue gas inlet 201, thereby allowing the cold air outside the oven body 200 to enter the high temperature flue gas inlet 201 through the cold air inlet 203, and then enter the rectifier channel 2053 through the high temperature flue gas inlet 201.

[0085] 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 rectifier channel 2053 through the cold air inlet 203, the cold air and the high-temperature flue gas can be mixed in the rectifier 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.

[0086] In some embodiments, the cold air inlet 203 is connected to the top of the rectifier channel 2053, and the high-temperature flue gas inlet 206 is formed at the bottom of the rectifier channel 2053.

[0087] Specifically, the oven body 200 is provided with a cold air inlet 203, which is connected to the rectifier channel 2053, and as shown in the figure. Figure 2As shown, the cold air inlet 203 is connected to the top of the rectifier channel 2053, meaning that cold air flows through the cold air inlet 203 to the top of the rectifier channel 2053 for circulation within the rectifier channel 2053. The high-temperature flue gas inlet 206 of the rectifier channel 2053 is formed at the bottom of the rectifier channel 2053, allowing high-temperature flue gas to flow through the high-temperature flue gas inlet 206 into the cooking chamber 204. The cold air can mix with the high-temperature flue gas within the rectifier channel 2053. Connecting the cold air inlet 203 to the top of the rectifier channel 2053 results in a longer distance between the mixing point of the cold air and high-temperature flue gas and the high-temperature flue gas inlet 206, thus allowing for thorough mixing of the cold air and high-temperature flue gas within the rectifier channel 2053. This ensures sufficient cooling of the high-temperature flue gas before it flows through the high-temperature flue gas inlet 206 into the cooking chamber 204 to cook the food, guaranteeing reliable cooling and improving cooking results.

[0088] 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 the rectifier flow channel 2053.

[0089] 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.

[0090] 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 rectifier flow channel 2053, so that the high-temperature flue gas that is fully disturbed and mixed in the main plate portion 2051 can flow along the rectifier flow 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.

[0091] In some embodiments, the exhaust port 202 is lower than the high-temperature flue gas inlet 201.

[0092] 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 cavity 204. This allows the high-temperature flue gas to enter the cooking cavity 204 through the high-temperature flue gas inlet 206 of the rectifier channel 2053 and flow upwards in the cooking cavity 204. This causes the cold air to flow downwards to the exhaust port 202 at the bottom of the cooking cavity 204 to be discharged from the cooking cavity 204. As a result, the high-temperature flue gas can gradually fill the entire cooking cavity 204, increasing the heating speed of the cooking cavity 204 and improving the user experience.

[0093] 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.

[0094] 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.

[0095] 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, thereby preventing the flame from flowing into the cooking chamber 204 and ensuring the reliability of the burner 20.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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 10 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.

[0105] 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:

[0106] 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.

[0107] 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.

[0108] 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 10 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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 8 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.

[0113] 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.

[0114] Optionally, such as Figures 9-10 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 5 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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 9-10 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] In some embodiments, such as Figure 9 and Figure 10 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.

[0129] 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.

[0130] In some embodiments, the air outlet 401 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 supplies air into the first mounting cavity 102, reducing the wind resistance during air flow, thereby reducing operating energy consumption and improving energy utilization.

[0131] In addition, the air inlet 401 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 air inlet 401 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 makes it easier for the fan assembly 40 to control the air flow into the first mounting cavity 102 and the second mounting cavity 103, thereby improving the reliability of air supply.

[0132] 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.
