[0042] The following examples are used to illustrate the present application, but the present application is not limited by these examples. Modifications to the specific embodiments of the present application or equivalent replacements to some technical features without departing from the spirit of the present application should be included in the scope of the technical solutions claimed by the present application.

[0043] Example 1

[0044] Reference Figures 1-2 The present embodiment provides a gas oven, which comprises an outer shell assembly 11, an inner container assembly 12, a combustion device (not shown in the figure) and an oven tray device 14. The inner container assembly 12 is arranged in the outer shell assembly 11, and a housing cavity 114 is formed at the upper end of the outer shell assembly 11 and located at the top of the inner container assembly 12 and opens upward. The housing cavity 114 is configured to be suitable for embedding a stove module 2 (see Figures 17-18). The inner container assembly 12 is internally provided with a cooking cavity 121 and a smoke blocking cavity 122 arranged in the front-rear direction, the cooking cavity 121 is used to discharge the waste gas and high-temperature smoke generated by combustion, and the smoke blocking cavity 122 is mainly used to discharge cooking oil fume, so as to reduce the interference between the cooking oil fume and the combustion smoke. The left and right side cavity walls of the cooking cavity 121 are respectively provided with support portions (not shown in the figure), which are configured to reliably support the baking tray device 14. The door body assembly 17 is rotationally connected to the inner container assembly 12, and is used to open or close the cooking cavity 121 of the inner container assembly 12. The smoke blocking cavity 122 and the cooking cavity 121 are provided with exhaust ports 1522 and mounting ports 1521 arranged in the up-down direction. At least one smoke exhaust port 123 is formed in the top or back upper end of the inner container assembly 12 and is in communication with the smoke blocking cavity 122, so that the cooking oil fume in the smoke blocking cavity 122 can be discharged upward in time through the smoke exhaust port 123. The upper end of the cooking cavity 121 is in communication with the upper end of the smoke blocking cavity 122 or the smoke exhaust port 123 through the exhaust port 1522, so that the combustion smoke in the cooking cavity 121 can be discharged upward from the exhaust port 1522.

[0045] The combustion device is arranged on the inner container assembly 12, and the smoke outlet end of the combustion device is in communication with the cooking cavity 121, which is used to provide combustion smoke for the cooking cavity 121. The baking tray device 14 is detachably placed in the cooking cavity 121, and the left and right ends thereof are respectively abutted against the support portions of the left and right side cavity walls of the cooking cavity 121. The baking tray device 14 is provided with a sealed cooking space 143 and an exhaust port 144, the free end of the exhaust port 144 extends into the mounting port 1521, and the cooking space 143 is in communication with the smoke blocking cavity 122 through the exhaust port 144.

[0046] When the combustion device works to generate combustion smoke, the combustion smoke fills the entire cooking cavity 121 to heat the baking tray device, and the condensed smoke and the waste gas generated during combustion are discharged through the exhaust port 1522 in the top middle and rear of the cooking cavity. The cooking oil fume and oil gas generated during cooking enter the smoke blocking cavity 121 through the exhaust port 144 of the baking tray device 14, and then continue to enter the smoke exhaust port 123 upward. Therefore, on the one hand, the combustion smoke is prevented from contacting the food in the baking tray device 14, and the generation of harmful substances in the food is reduced. On the other hand, the cooking cavity 121 and the combustion device are both isolated from the cooking oil fume, so as to avoid the oil splashed from the food during cooking from falling into the cooking cavity 121 and the combustion device, to avoid the risk of fire caused by red fire, insufficient combustion and oil accumulation, and to make the cooking cavity 121 easier to clean.

[0047] Reference Figures 1-2The shell assembly 11 is formed by the oven bottom plate 111, the two oven side plates 112 and the oven back plate 113, and has a front opening and a top opening. The inner liner assembly 12 is installed in the shell assembly 11 and covers the front opening of the shell assembly 11. The accommodating cavity 114 is formed by the upper ends of the two oven side plates 112, the upper end of the oven back plate 113 and the top of the inner liner assembly 12.

[0048] With reference to Figures 1-2 Further, the gas oven further comprises a smoke baffle 15. The inner liner assembly 12 is provided with a cavity 1202 facing the front opening. The smoke baffle 15 is arranged in the cavity 1202 and has its upper end connected to the top of the inner liner assembly 12 and its lower end connected to the bottom rear side or back of the inner liner assembly 12. The left and right ends of the smoke baffle 15 are respectively abutted against or connected to the left and right side walls of the inner liner assembly 12. The smoke baffle 15 divides the cavity 1202 into a cooking cavity 121 and a smoke baffle cavity 122 arranged in front of and behind the cooking cavity 121. An installation opening 1521 is formed in the middle of the smoke baffle 15. An exhaust opening 1522 is arranged at the upper end of the smoke baffle 15 or between the smoke baffle 15 and the top of the inner liner assembly 12. The smoke baffle cavity 122 can isolate the cooking oil fume without affecting the exhaust of the cooking cavity 121, so as to prevent the cooking cavity and the combustion device from being polluted by the cooking oil or the cooking oil fume.

[0049] With reference to Figures 1-2 The combustion device comprises two oven burners 13 arranged above and below the inner liner assembly 12. The smoke outlet end of the oven burner 13 is connected to the cooking cavity 121 to form a "bottom + top combined combustion system". Compared with the existing electric oven, the gas oven reduces the complex components such as electric heating pipes, power panels and control panels, simplifies the heating system of the oven module 1, has a simple structure, uses gas as the heat source for food cooking, has a high gas calorific value and a faster heating speed, and is beneficial to improving the cooking efficiency. In this embodiment, a lower combustion chamber 115 is formed between the oven bottom plate 111 and the bottom of the inner liner assembly 12. A plurality of bottom smoke inlet holes 124 are formed in the bottom of the inner liner assembly 12. The cooking cavity 121 and the lower combustion chamber 115 are connected through the plurality of bottom smoke inlet holes 124. A top installation opening is formed in the top of the inner liner assembly 12 and connected to the cooking cavity 121. One of the oven burners 13 is installed at the top installation opening and has its smoke outlet end connected to the cooking cavity. The other oven burner 13 is installed in the lower combustion chamber 115 and the combustion fume generated by the working of the oven burner 13 flows into the cooking cavity through the bottom smoke inlet holes 124.

[0050] In the embodiment, the bottom air inlet hole 1111 is formed on the oven bottom plate 111 and communicates with the lower combustion chamber 115, and the front air inlet hole 1201 is formed on the inner container front plate lower end of the inner container assembly 12 and communicates with the lower combustion chamber 115, so as to supply the secondary air required for the oven burner 13 installed in the lower combustion chamber 115 to burn more fully.

[0051] Specifically, the free end of the air outlet 144 protrudes outwardly from the rear outer edge of the baking tray device 14, so that the free end of the air outlet 144 is inserted into the mounting port and communicates with the smoke blocking cavity 122. The air outlet 144 of the baking tray device 14 is trapezoidal with a large lower end and a small upper end, and the diameter of the air outlet 144 gradually increases from the cooking space 143 outwardly, so that the cooking oil fume in the cooking space 143 is quickly discharged into the smoke blocking cavity 122 through the air outlet 144.

[0052] The specific structure of the baking tray device 14 includes but is not limited to any one of the following:

[0053] Reference Figures 2-5 The first kind, the baking tray device 14 includes a base 141 and an upper cover 142, the base 141 is provided with an upwardly open containing area 1411, and the upper cover 142 is detachably covered on the top of the base 141. The upper cover 142 and the containing area 1411 form a sealed cooking space 143, and the air outlet 144 is formed at the position of the upper cover 142 corresponding to the mounting port 1521, or the air outlet 144 is formed between the upper cover 142 and the base 141. Specifically, the upper cover 142 is provided with an upwardly extending and downwardly open upper concave cavity 1421, which surrounds the cooking space 143 with the containing area 1411, so that the height and volume of the cooking space 143 are larger, which is suitable for accommodating food with larger volume, and at the same time, it is beneficial to strengthen the overall strength of the upper cover.

[0054] A protruding part (not shown in the figure) is protruded upwardly at the bottom of the containing area 1411 and used for supporting food, so as to reduce the contact area between the food and the base 141 and reduce the risk of being burnt; and / or a liquid storage groove (not shown in the figure) is recessed upwardly at the bottom outside of the containing area 1411, so as to inject clean water into the liquid storage groove before cooking, which can keep the food moist and avoid being burnt. In addition, the liquid storage groove can be used to collect oil during cooking.

[0055] Specifically, the protrusions can be large bosses formed by locally punching upward from the bottom of the holding area 1411 (i.e., the bottom of the base 141) for rapid prototyping; or the protrusions include at least one row of protrusion groups, each of which includes a plurality of small bosses 1412 arranged side by side in the left-right or front-back direction, and a channel for passing fluid such as oil is formed between adjacent two small bosses 1412, the small bosses 1412 are formed by locally punching upward from the bottom of the holding area 1411 (i.e., the bottom of the base 141) for rapid prototyping, which is conducive to strengthening the strength of the base 141. The small bosses 1412 can be any one of trapezoidal, conical or hemispherical shape with large lower end and small upper end, or rectangular shape.

[0056] Specifically, the liquid storage groove can be an annular groove arranged at the periphery of the protrusions; or the liquid storage groove includes two strip-shaped grooves 1413 arranged oppositely, and each of the two strip-shaped grooves 1413 is arranged at the left or right side or the front or back side of the holding area, and each of the two strip-shaped grooves 1413 is located at the opposite side of the protrusions. The annular groove or the strip-shaped groove 1413 is formed by locally punching downward from the bottom of the holding area 1411 (i.e., the bottom of the base 141) for rapid prototyping, which is conducive to strengthening the strength of the base 141. In this embodiment, the lower end of the liquid storage groove protrudes downward from the bottom surface of the base 141, i.e., the lower end of the annular groove or the strip-shaped groove 1413 extends downward below the bottom surface of the base 141, so that the liquid storage groove (i.e., the annular groove or the strip-shaped groove 1413) can serve as a supporting leg to reliably support the baking tray device 14, which is conducive to improving the stability of the baking tray device.

[0057] The lower convex edge 1414 extending outward and located at the periphery of the holding area 1411 is integrally formed on the top periphery of the base 141, and the upper cover 142 is integrally formed with an upper convex edge 1422 extending outward at a position corresponding to the lower convex edge 1414 (see Figure 5 ), so as to form a surface-to-surface contact and improve the air tightness therebetween, which not only prevents the combustion flue gas from entering the cooking space and contacting the food through the space between the upper convex edge and the lower convex edge, but also prevents the cooking flue gas from flowing out through the space between the upper convex edge and the lower convex edge to pollute the cooking cavity 121 or the combustion device.

[0058] Reference Figures 6-7, the second kind, which is distinguished from the first kind in that a plurality of vent holes are formed on the baking tray device 14 outside the cooking space 143 and are used for the airflow to pass through, and when the baking tray device 14 divides the cooking space into two parts, the two parts can be connected through the vent holes, so as to better realize the uniformity of the temperature field in the cooking cavity. Specifically, a plurality of positioning holes 1423 are formed on the upper convex edge 1422 of the upper cover 142 for the airflow to pass through, and the lower convex edge 1414 of the base 141 is provided with a flange hole 1415 extending upward and for the airflow to pass through at the position corresponding to the positioning hole, the flange hole 1415 constitutes a vent hole, and the flange hole 1415 is inserted into the corresponding positioning hole 1423, so that under the cooperation of the flange hole 1415 and the corresponding positioning hole 1423, not only can the upper cover be quickly positioned and fixed on the base, effectively preventing the risk of falling during installation, but also can play a role in quickly rising heat, better realizing the uniformity of the temperature field in the cooking cavity 121. Of course, the positions of the positioning hole and the flange hole can also be exchanged, that is, the positioning hole is formed on the lower convex edge 1414 of the base 141, and the flange hole is arranged on the upper convex edge 1422 of the upper cover 142 and extends downward, so that the flange hole of the upper convex edge can extend downward into the positioning hole of the lower convex edge.

[0059] Reference Figures 8-9 , the third kind, which is distinguished from the first kind or the second kind in that a dome 1424 is arranged on the top of the upper concave cavity 1421 of the upper cover 142, the dome 1424 is formed by locally punching upward from the top of the upper concave cavity 1421, and the orthographic projection of the dome 1424 covers the entire convex part, so as to increase the cooking space 143, and the oil drops and water drops on the top of the dome 1424 can smoothly drop along the oil path to the designated position of the base 141, that is, to the area at the bottom of the holding area 1411 outside the periphery of the convex part, avoiding pollution of the food or affecting the taste of the food. It is particularly noted that the top of the dome 1424 gradually decreases from front to back along the length direction thereof, and the low end of the top of the dome 1424 is arranged close to the air outlet, so that the smoke and water vapor generated during cooking condense into water drops along the lowest part of the top of the dome 1424 and fall into the base 141, forming a path for the condensation of water vapor, avoiding the condensation water drops formed on the top of the upper cover 142 from falling onto the food being cooked, affecting the taste of the food.

[0060] Reference Figures 10-11, the fourth kind, which is distinguished from the third kind in that a plurality of flow guide grooves 1425 are further provided on the upper cover 142, the plurality of flow guide grooves 1425 are arranged side by side and spaced apart in the left-right direction on the top of the dome 1424 and are in communication with the cooking space 143, the flow guide grooves 1425 are formed by locally stamping upward from the top of the dome 1424, the front and rear ends of the flow guide grooves 1425 protrude out of or are flush with the front and rear ends of the protruding portion, the flow guide grooves 1425 are used to guide water droplets or oil droplets to the front and rear ends of the protruding portion or outside the front and rear ends, so that the falling point of the water droplets or oil droplets is located in the area outside the protruding portion. Since the protruding portion area of the base is used to place food, such design avoids water droplets or oil droplets falling on the food. Of course, the dome can also be omitted, and the plurality of flow guide grooves 1425 can be arranged side by side and spaced apart in the left-right direction on the top of the upper cavity 1421 and in communication with the cooking space 143. It is particularly pointed out that the flow guide grooves 1425 gradually decrease from front to back along the length direction thereof, and the lower end of the flow guide grooves is arranged close to the air outlet, so that the smoke and water vapor generated during cooking fall into the base 141 along the lowest part of the flow guide grooves 1425, forming a condensed water vapor path, avoiding the condensed water droplets formed on the top of the upper cover 142 from falling on the food being cooked, resulting in poor taste of the food. In addition, the size of the flow guide grooves 1425 gradually decreases along the length direction thereof, so as to better guide the condensed water or condensed oil.

[0061] The specific structure of the smoke baffle 15 includes but is not limited to any one of the following:

[0062] With reference to Figures 1-2 and Figures 12-13 , the first kind, the smoke baffle 15 includes a lower flow guide section 151 and an upper smoke blocking section 152 which are fixedly connected and arranged at an angle, one end of the lower flow guide section 151 away from the upper smoke blocking section 152 is connected with the bottom rear side of the inner container assembly 12, and the upper end of the upper smoke blocking section 152 is connected with the top of the inner container assembly 12, so as to divide the cavity of the inner container assembly 12 into a cooking cavity and a smoke blocking cavity. The mounting port 1521 is provided at the lower end of the upper smoke blocking section 152, which is adapted for the free end of the air outlet 144 of the baking tray device 14 to pass through. The exhaust port 1522 is provided at the upper end of the upper smoke blocking section 152 or between the upper smoke blocking section 152 and the top of the inner container assembly 12. In this embodiment, the exhaust port 1522 is opened at the upper end of the upper smoke blocking section 152.

[0063] In the embodiment, the lower flow guide section 151 and the upper smoke blocking section 152 are arranged at an obtuse angle, and the lower flow guide section 151 is arranged to tilt downward and rearward, so as to quickly guide the heat of the combustion flue gas to the bottom of the grill device 14 through the lower flow guide section 151, so that the food in the grill device 14 can be heated more quickly. The lower installation surface 1511 extending rearward is fixed at the bottom of the lower flow guide section 151, and the lower installation surface 1511 is fixedly connected to the bottom of the inner container assembly 12. The upper installation surface 1524 extending forward or rearward is fixed at the top of the upper smoke blocking section 152, and the upper installation surface 1524 is fixedly connected to the top of the inner container assembly 12.

[0064] Specifically, the annular flange 1523 extending rearward is integrally formed at the periphery of the installation opening 1521, so as to strengthen the strength of the smoke blocking cover and further reliably support the air outlet 144 of the grill device 14. The exhaust opening 1522 is arranged to tilt upward and rearward, so that the exhaust opening itself can play a flow guide role, so as to quickly exhaust the smoke and reduce the mutual interference between the cooking oil fume and the combustion flue gas; and / or the diameter of the exhaust opening 1522 gradually increases from bottom to top, so as to quickly exhaust the smoke. In the embodiment, the exhaust opening 1522 includes the lower bottom surface 1531 and the two lateral surfaces 1532. The lower bottom surface 1531 is arranged to tilt upward and rearward, and the high end of the lower bottom surface 1531 extends toward the smoke exhaust opening 123. The top of the high end of the lower bottom surface 1531 is in clearance fit or abutment with the lower end surface of the smoke exhaust opening 123. The two lateral surfaces 1532 are integrally formed upward and outward from the left and right ends of the lower bottom surface 1531, so as to form an inverted "8" shape by surrounding the two lateral surfaces 1532.

[0065] Reference Figures 14-16, the second kind, the difference between the first kind is that the lower flow guide section 151 is connected to the lower end or middle part of the back of the inner container assembly 12 away from the end of the upper smoke blocking section 152. In this embodiment, the lower flow guide section 151 and the upper smoke blocking section 152 are arranged at an acute angle, and the lower flow guide section 151 is arranged obliquely upward and backward, the free end of the lower flow guide section 151 is higher than the upper edge of the air outlet 144, and a rear mounting surface 1512 extending upward or downward is fixed at the rear end of the lower flow guide section 151, and the rear mounting surface 1512 is connected to the back of the inner container assembly 12. Thus, by designing the lower flow guide section 151 to be arranged obliquely upward and backward, on the one hand, after the combustion flue gas rises in the rear of the cooking cavity 121, it is refracted after passing through the lower flow guide section 151 of the smoke blocking cover 15, and then flows toward the baking tray device 14 to heat the food in the baking tray device 14, and on the other hand, when the cooking flue gas generated by the heating of the food in the baking tray device 14 flows into the smoke blocking cavity 122 through the air outlet 144, the cooking flue gas is refracted to flow obliquely upward when passing through the lower flow guide section 151 of the smoke blocking cover 15, which is consistent with the exhaust flow path, thereby improving the exhaust efficiency. If there is no lower flow guide section 151 arranged obliquely upward and backward, the cooking flue gas in the baking tray device 14 will directly contact the back of the inner container assembly 12 after entering the smoke blocking cavity 122 through the air outlet, and then be reflected back. The airflow reflected back will interfere with each other and affect each other, which will hinder the discharge efficiency of the cooking flue gas, and finally cause the cooking flue gas to be discharged outside the cooking cavity 121, thereby causing oil pollution to the inner container assembly 12 or the combustion device.

[0066] Reference Figures 14-16 , the third kind, the difference between the first kind or the second kind is that a flow dividing surface 1533 extending upward is fixed at one end of the lower bottom surface 1531 of the air outlet 144 close to the smoke blocking cavity 122, the lower end of the flow dividing surface 1533 is integrally formed with the lower bottom surface 153, the upper end of the flow dividing surface 1533 abuts against the top of the inner container assembly 12, and the flow dividing surface 1533 divides the lower end surface of at least one smoke exhaust port 143 into a front part and a rear part, the front part is used to communicate with the cooking cavity 121 through the air outlet 144, and the rear part is used to directly communicate with the smoke blocking cavity 122, so that the smoke blocking cavity 122 and the cooking cavity 121 are independent of each other, and the flue gas entering the smoke exhaust port 143 from the smoke blocking cavity 122 and the cooking cavity 121 does not interfere with each other. In addition, an upward extending flow dividing part 1534 is integrally formed at the top of the flow dividing surface 1533 corresponding to the position of the smoke exhaust port 143, the flow dividing part 1534 is inserted into the corresponding smoke exhaust port and divides the smoke exhaust port into a front smoke inlet and a rear smoke inlet, the front smoke inlet communicates with the cooking cavity 121 through the air outlet 1522, and the rear smoke inlet directly communicates with the smoke blocking cavity 122.

[0067] Reference Figures 1-2Further, the gas oven further comprises a smoke exhaust device 16, which is arranged at the top of the inner container assembly 12 and corresponds to the smoke exhaust port 123. The opposite ends of the smoke exhaust device 16 are respectively connected with the smoke exhaust port 123 and the external atmosphere, so as to facilitate the centralized exhaust of the flue gas through the smoke exhaust device 16. Specifically, the smoke exhaust device 16 comprises a smoke exhaust cover 161 and a fixing bracket 162. The smoke exhaust cover is fixedly installed on the top of the inner container assembly 12 through the fixing bracket. The lower end of the smoke exhaust cover is arranged at the periphery of the corresponding smoke exhaust port 123 and is connected with the corresponding smoke exhaust port 123.

[0068] Embodiment 2

[0069] Reference Figure 17 The difference between the present embodiment and Embodiment 1 is that the specific installation positions of the two oven burners 13 are different. In the present embodiment, the two oven burners 13 are respectively arranged on the left and right sides of the inner container assembly 12 and are connected with the cooking cavity 121 at the flue gas outlet end. Specifically, two side combustion chambers 116 are formed between the outer shell assembly 11 and the inner container assembly 12 and are arranged on the left and right outer sides of the inner container assembly 12. Side openings (not shown in the figure) are respectively arranged on the left and right side walls of the cooking cavity. The side combustion chambers 116 are connected with the cooking cavity through the side openings. The two oven burners 13 are respectively arranged in the two side combustion chambers 115. The flue gas outlet end of the oven burner 13 is connected with the cavity 1121 through the corresponding side opening, or the flue gas outlet end of the oven burner 13 penetrates through the corresponding side opening and extends into the cavity 1121.

[0070] In addition, an air inlet channel (not shown in the figure) is arranged between the outer shell assembly 11 and the inner container assembly 12. The bottom air inlet hole and / or the front air inlet hole are connected with the side combustion chamber 115 through the air inlet channel, so as to supply secondary air for the oven burner 13 arranged in the side combustion chamber 115.

[0071] It can be seen that, by arranging the two oven burners 13 on the left and right sides of the cooking cavity, the oil stains or cleaning water accumulated at the bottom of the cavity can be prevented from penetrating into the lower part through the bottom smoke inlet hole and causing poor cleaning. The lower area of the inner container assembly 12 is effectively prevented from being contaminated, and cleaning is facilitated.
