Technical Field

[0001] The utility model relates to the technical field of cooking devices, in particular to an oven and cooking all-in-one machine. Background Art

[0002] With the development of technology, the degree of integration of all-in-one cooking machines has gradually increased. The versatility of all-in-one cooking machines can meet the diverse needs of daily cooking, while ovens provide professional support in baking and roasting. Gas ovens can provide better cooking results, so many users choose to use gas ovens.

[0003] In the related art, an oven includes an inner container and an exhaust pipe, which is connected to the oven and is used to discharge the gas when the gas in the oven expands due to heat.

[0004] However, when the oven first starts working, it is in a cold combustion state. Since the air temperature inside the oven is low and the air heat exchange process is slow, more combustion products are easily produced in the process of reaching the optimal combustion state. The oven discharges the combustion products slowly, and the combustion products hinder combustion, resulting in the oven taking a long time to reach the optimal cooking state, affecting cooking efficiency.

[0039] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, when describing pipelines or channels, the "connected" and "connected" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0043] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0044] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0045] A multifunctional kitchen appliance typically integrates multiple cooking functions, including steaming, boiling, stir-frying, broiling, and baking. Combining at least two of the following cooking appliances—a steamer, oven, microwave, gas stove, and range hood—they save space.

[0046] An oven is a common kitchen appliance used to heat and bake food using hot air. It works by evenly distributing heat to the food being cooked, using either electric or gas heating elements. Ovens are suitable for a variety of cooking methods, including baking, roasting, baking, and toaster ovens. They are widely used for making bread, cakes, cookies, meat, pizza, and other delicacies.

[0047] The main types of ovens include electric ovens, gas ovens, and microwave ovens. Gas ovens are widely favored because they provide better taste and flavor for cooked food. Furthermore, gas ovens can still function normally during power outages or brownouts, providing greater flexibility and reliability.

[0048] Integrating an oven with other cooking appliances, such as a stove, allows for a more efficient cooking experience. Users can pre-process or heat ingredients in the stovetop before transferring them to the oven for the final toasting. This combination not only saves time but also maximizes the strengths of each appliance, enhancing the taste and nutritional value of food.

[0049] In a gas oven, the optimal combustion temperature range of the burner is: 1300-1400 degrees Celsius.

[0050] When an oven starts operating, the low internal temperature results in significant heat radiation losses, preventing it from reaching the optimal combustion temperature quickly. This slows the heat exchange process within the oven, which in turn leads to the production of more combustion products as the oven reaches the optimal temperature. Related art ovens are equipped with an inner liner and an exhaust pipe, which is used to discharge the gas as it expands. However, the exhaust pipe's slow rate of exhausting combustion products can delay the oven's optimal cooking time, affecting cooking efficiency.

[0051] To facilitate the description of the following embodiments, before introducing the embodiments of the present application, some professional terms that will be mentioned in the embodiments of the present application are first introduced, specifically:

[0052] Cold combustion: Cold combustion means that before reaching the optimal combustion temperature, the air in the combustion environment is colder (compared to the optimal combustion temperature), the oxygen saturation is low, the gas heat exchange process is slow, and the combustion is incomplete.

[0053] like Figure 1 As shown, Figure 1 This is one of the structural schematic diagrams of the oven 100 provided in an embodiment of the present application.

[0054] In order to solve the above technical problems, the present application provides an oven 100.

[0055] The oven 100 provided in the present application includes an inner container 1 , and a receiving cavity 11 is formed inside the inner container 1 , and the receiving cavity is used to place items that need to be heated.

[0056] like Figure 2 As shown, Figure 2 This is one of the structural diagrams of the inner container 1 of the oven 100 provided in the embodiment of the present application. The inner container 1 includes side walls 12 and a top wall 13. It should be noted that the top wall 13 refers to the side wall 12 and the top wall 13 when the oven 100 (see Figure 1 ) When placed on the ground, the wall of the inner liner 1 away from the ground is the top wall 13.

[0057] like Figure 3 As shown, Figure 3 This is the second structural diagram of the oven 100 provided in the embodiment of the present application. Figure 2 and Figure 3 The oven 100 provided in the present application includes an exhaust gas discharge structure 2. One end of the exhaust gas discharge structure 2 is connected to the side wall 12 or the top wall 13 of the inner container 1, and one end of the exhaust gas discharge structure 2 is connected to the accommodating cavity 11, and the other end of the exhaust gas discharge structure 2 is connected to the external space of the accommodating cavity 11. In this way, the exhaust gas discharge structure 2 connects the inside of the accommodating cavity 11 with the outside of the accommodating cavity 11, and the air and combustion generated in the accommodating cavity 11 can be discharged to the outside of the accommodating cavity 11 through the exhaust gas discharge structure 2.

[0058] The exhaust gas discharge structure 2 is used to open when the internal temperature of the accommodating chamber 11 is lower than a preset value, and to close when the internal temperature of the accommodating chamber 11 is greater than or equal to the preset value.

[0059] It should be noted that the temperature preset value is related to the set temperature and cooking mode. Specifically, the set temperature can be the oven 100 temperature set by the user, or different cooking modes correspond to different temperatures. For example, when the user sets the required baking temperature to 200 degrees Celsius, the oven 100 starts to work and the temperature rises. During this process, the exhaust gas exhaust structure 2 is opened. When the temperature inside the oven 100 reaches 200 degrees Celsius, the exhaust gas exhaust structure 2 is closed.

[0060] Therefore, through the above structure, when the oven 100 starts to work, the air in the oven 100 is lower than the preset temperature. Due to the low temperature, the gas heat exchange process is slow, and the combustion process is not smooth. At this time, it is in a cold combustion state. During this process, a large amount of combustion products are generated in the cold combustion state. The exhaust gas discharge structure 2 can release the combustion products to the outside of the accommodating cavity in time and increase the speed of combustion product discharge. After the exhaust gas discharge structure 2 discharges the combustion products from the accommodating cavity 11, the proportion of oxygen in the air in the accommodating cavity can be increased, and the hindering effect of combustion products on combustion can be reduced, so that the combustion is sufficient, the combustion efficiency is improved, the time required for the oven 100 to reach the preset temperature is reduced, and the speed at which the oven 100 reaches the preset temperature is increased.

[0061] When the temperature in the accommodating chamber 11 reaches a preset temperature value, the exhaust gas discharge structure 2 is closed, which can maintain the internal temperature of the accommodating chamber 11, reduce heat loss, and thus reduce energy waste.

[0062] It should be noted that the oven 100 provided in the present application includes an exhaust pipe 5, which is connected to the inner pot 1. The exhaust gas discharge structure provided in the present application and the exhaust pipe 5 are not the same component.

[0063] The embodiments of the present application are described in detail below with reference to the accompanying drawings. Before describing the embodiments of the present application in detail, the application scenarios of the embodiments of the present application are first introduced.

[0064] like Figure 4 As shown, Figure 4 This is a structural diagram of the cooking machine 200 provided in an embodiment of the present application.

[0065] Combine Figure 2 、 Figure 3 and Figure 4 The present application provides an oven 100 and a cooking machine 200, wherein the cooking machine 200 includes the oven 100. The oven 100 is an oven 100 with combustion characteristics such as a gas oven, a steam oven, a convection oven, etc.

[0066] The embodiments provided in this application may also have other application scenarios. For example, the oven 100 may be an electric oven 100, a microwave oven 100, or other ovens 100 that do not have combustion characteristics.

[0067] In this application scenario, the exhaust gas discharge structure 2 can assist the exhaust pipe in discharging gas. When the gas in the oven 100 undergoes thermal expansion, it can be discharged through the exhaust gas discharge structure 2.

[0068] In one application scenario, when the oven 100 heats food with high dehumidification requirements (for example, soluble beans, dried fruits and vegetables, cakes, puffs, frozen foods, etc.), efficient dehumidification is required, and the exhaust gas discharge structure 2 discharges the steam or speeds up the steam discharge.

[0069] By opening and closing the exhaust gas discharge structure 2, the humidity inside the accommodating chamber 11 can be controlled. Specifically, closing the exhaust gas discharge structure 2 slows down the dehumidification rate of the accommodating chamber 11 (steam can be discharged through the exhaust pipe), thereby maintaining the humidity inside the accommodating chamber 11. Opening the exhaust gas discharge structure 2 accelerates the steam discharge rate in the accommodating chamber 11, thereby quickly reducing the humidity.

[0070] For example, during the cooking process, when processing food that requires a higher crispness, opening the exhaust gas discharge structure 2 to quickly discharge the steam generated during the cooking process can improve the taste of the food, thereby meeting the user's cooking needs and improving the user's experience.

[0071] like Figure 5 As shown, Figure 5 Provided in the embodiments of this application Figure 3 One of the cross-sectional diagrams taken along the AA axis. In one possible embodiment, the exhaust gas discharge structure 2 includes an exhaust gas discharge pipe 21. The exhaust gas discharge pipe 21 is connected to the inner liner 1, and the combustion products and water vapor generated in the accommodating chamber 11 can be discharged out of the accommodating chamber 11 through the exhaust gas discharge pipe 21.

[0072] In one possible embodiment, the exhaust gas discharge structure 2 includes a valve 22, which is disposed in the exhaust gas discharge pipe 21. The valve 22 can open or close the exhaust gas discharge pipe 21.

[0073] For example, the valve 22 may be an electric valve 22 , a pneumatic valve 22 , a regulating valve, a check valve, an exhaust valve, a filter valve, a manual valve 22 or other valves 22 .

[0074] Continue to see Figure 5 In a possible implementation manner, the oven 100 further includes a temperature detector 3 . The temperature detector 3 is used to detect the internal temperature of the accommodating cavity 11 .

[0075] Exemplarily, the temperature detector 3 includes but is not limited to the following types of temperature detectors 3: a thermocouple detector, a thermistor detector, a platinum resistance detector, an infrared temperature sensor, and the like.

[0076] like Figure 6 As shown, Figure 6 A schematic diagram of the controller connection structure provided in an embodiment of the present application.

[0077] Combine Figure 5 and Figure 6 In one possible embodiment, the oven 100 further includes a controller 4. The temperature detector 3 is electrically connected to the controller 4. The controller 4 controls the valve 22 to close when the temperature detector 3 detects that the internal temperature of the accommodating cavity 11 is lower than a preset value, or when the temperature detector 3 detects that the internal temperature of the accommodating cavity 11 is greater than or equal to a preset value.

[0078] The preset value of the internal temperature of the accommodating cavity 11 may be a temperature value set by the user, or different cooking modes may correspond to different temperatures.

[0079] There are at least two application scenarios in which the internal temperature of the accommodating cavity 11 is lower than the preset value, one of which is during the heating process of the oven 100 , and the other is during the heat dissipation process after the oven 100 is used.

[0080] During the heating process of the oven 100 , the control valve 22 is opened to accelerate the discharge of combustion products, and can also accelerate the discharge of air when the air expands thermally, thereby balancing the pressure inside and outside the accommodating cavity 11 .

[0081] During the heat dissipation process after the oven 100 is used, the control valve 22 is opened to allow the heat to be discharged from the exhaust gas discharge pipe 21 along with the air, thereby accelerating the heat dissipation.

[0082] In one possible embodiment, controller 4 controls valve 22 to open within a rated time after oven 100 starts operating or within a rated time after oven 100 stops operating, and controls valve 22 to close after the rated time after oven 100 starts operating. The rated time may be set by the user or determined by a cooking mode or cooking item.

[0083] In a possible embodiment, the oven 100 includes a door body, which is connected to the inner pot 1 and is used to open or close the accommodating cavity 11. The door body is well understood by those skilled in the art.

[0084] When the door opens the accommodating cavity 11, the user can put in or take out items to be cooked or items after cooking through the door.

[0085] When the door is closed, it can isolate the internal heat, prevent heat loss, improve the energy efficiency of oven 100, and protect the user from burns. At the same time, a good seal between the door and the inner tank 1 can ensure the sealing of the oven 100, maintain a stable temperature, and help the food be heated evenly.

[0086] For example, the door body can be made of transparent glass, or a transparent glass window can be provided on the door body, so that the user can observe the cooking status of the food without opening the oven 100, thereby avoiding heat loss caused by frequent opening of the door.

[0087] like Figure 7 As shown, Figure 7 This is the second structural schematic diagram of the inner container 1 of the oven 100 provided in an embodiment of the present application.

[0088] In one possible embodiment, the side wall 12 includes a first side wall 121 and a second side wall 122 that are opposite to each other, and the first side wall 121 and the second side wall 122 both intersect and are connected to the top wall 13. The side wall 12 also includes a third side wall 123 that is opposite to the door body, and the third side wall 123 is connected to the first side wall 121, the second side wall 122 and the top wall 13. One end of the exhaust gas exhaust pipe 21 is connected to one of the first side wall 121, the second side wall 122 or the third side wall 123.

[0089] The oven 100 also includes other devices, such as a fan, burners, ventilation ducts, motors, humidifiers, water tanks, etc., and these cooking-assisting devices occupy space inside the oven 100. The exhaust duct 21 can be flexibly connected to one of the first side wall 121, the second side wall 122, or the third side wall 123.

[0090] For example, when other devices are installed on the side of the first side wall 121 away from the accommodating chamber 11 or the space on the side of the first side wall 121 away from the accommodating chamber 11 is occupied, the exhaust gas discharge pipe 21 can be connected to the second side wall 122 or the third side wall 123 .

[0091] For example, when other devices are installed on the side of the second side wall 122 away from the accommodating chamber 11 or the space on the side of the second side wall 122 away from the accommodating chamber 11 is occupied, the exhaust gas discharge pipe 21 can be connected to the first side wall 121 or the third side wall 123 .

[0092] Exemplarily, when other devices are installed on the side of the third sidewall 123 away from the accommodating chamber 11 or the space on the side of the third sidewall 123 away from the accommodating chamber 11 is occupied, the exhaust gas discharge pipe 21 can be connected to the first sidewall 121 or the second sidewall 122 .

[0093] For example, when other devices are installed on the side of the side wall 12 away from the accommodating chamber 11 or the space on the side of the side wall 12 away from the accommodating chamber 11 is occupied, the exhaust gas discharge pipe 21 can be connected to the top wall 13. The side wall 12 includes a first side wall 121, a second side wall 122 and a third side wall 123.

[0094] like Figure 8 As shown, Figure 8 Provided in the embodiments of this application Figure 3 One of the cross-sectional diagrams of the AA back view. Figure 5 、 Figure 7 and Figure 8 As shown, in a possible embodiment, one end of the exhaust gas discharge pipe 21 is connected to a position close to the top wall 13 in the first side wall 121 , the second side wall 122 or the third side wall 123 .

[0095] Gas oven 100 (see Figure 1 ) The fuel used is usually natural gas or liquefied petroleum gas. During the combustion of the fuel, water vapor, carbon dioxide, carbon monoxide, nitrogen oxides and other substances will be produced, and carbon dioxide, carbon monoxide, nitrogen oxides and other substances will affect the air quality.

[0096] In one possible embodiment, the side wall 12 includes an upper side wall 16 and a lower side wall 17. The upper side wall 16 is located on a side of the lower side wall 17 close to the top wall 13, and the upper side wall 16 is connected to the lower side wall 17. The upper side wall 16 includes at least part of a first side wall 121, a second side wall 122, and a third side wall 123.

[0097] For example, the dividing line between the upper side wall 16 and the lower side wall 17 is a line along the horizontal direction that divides the side wall 12 into two parts, such as Figure 5 or Figure 8 Line L1 and line L2 in.

[0098] Exemplarily, the dividing line between the upper side wall 16 and the lower side wall 17 extends in the horizontal direction and is located at two-thirds of the distance from the lower side wall 17 to the upper side wall 16. Specifically, the area of ​​the lower side wall 17 is two-thirds of the area of ​​the side wall 12, and the area of ​​the upper side wall 16 is one-third of the area of ​​the side wall 12. Figure 5 or Figure 8 Line L2 in.

[0099] Exemplarily, the upper side wall 16 is located on a side of the lower side wall 17 close to the top wall 13 , and the boundary line between the upper side wall 16 and the lower side wall 17 can be set according to actual usage.

[0100] According to physical principles, hot air is lighter than cold air. Therefore, when oven 100 is heated, substances such as carbon dioxide, carbon monoxide, and nitrogen oxides are generated and located above accommodating cavity 11. Exhaust gas discharge duct 21 is connected to upper sidewall 16 of oven 100 to facilitate the discharge of substances such as carbon dioxide, carbon monoxide, and nitrogen oxides.

[0101] It should be noted that, in the cooking machine 200 (see Figure 4 ), oven 100 (see Figure 1 ) other cooking equipment needs to be installed above the oven 100, and the exhaust gas exhaust pipe 21 is connected to the side wall 12 to save space above the oven 100, making it convenient to install other cooking equipment.

[0102] like Figure 9 As shown, Figure 9 Provided in the embodiments of this application Figure 3 The second cross-sectional diagram in the AA direction. Figure 10 As shown, Figure 10 Provided in the embodiments of this application Figure 3 The second cross-sectional diagram with AA facing away from the center.

[0103] In one possible embodiment, the first side wall 121 and the second side wall 122 include a front side wall 14 and a rear side wall 15, the rear side wall 15 is located on the side of the front side wall 14 away from the door body, the front side wall 14 is connected to the rear side wall 15, and one end of the exhaust gas exhaust pipe 21 is connected to the rear side wall 15.

[0104] Exemplarily, the dividing line between the front side wall 14 and the rear side wall 15 extends in the height direction and is located halfway from the door body to the third side wall 123, for example, Figure 9 or Figure 10 Specifically, the area of ​​the front side wall 14 is half of the area of ​​the first side wall 121 and half of the area of ​​the second side wall 122, and the area of ​​the rear side wall 15 is the other half of the area of ​​the first side wall 121 and the other half of the area of ​​the second side wall 122.

[0105] Exemplarily, the dividing line between the front side wall 14 and the rear side wall 15 extends in the height direction and is located at two-thirds of the direction from the door body to the third side wall 123. For example, Figure 9 or Figure 10 Line L4 in.

[0106] For example, the boundary line between the front side wall 14 and the rear side wall 15 can be specifically set according to actual usage.

[0107] One end of the exhaust gas discharge pipe 21 is connected to the rear side wall 15. During the combustion process, when combustion products are generated, the combustion products are discharged through the exhaust gas discharge pipe 21 set on the rear side wall 15. The combustion products flow toward one end of the exhaust gas discharge pipe 21 in the accommodating cavity 11, reducing the flow of combustion products toward the door body, thereby reducing the harm of combustion products to the user when the user opens the door body.

[0108] In a possible implementation, one end of the exhaust gas discharge pipe 21 is connected to the top wall 13 .

[0109] According to physical principles, hot air is lighter than cold air. Therefore, when oven 100 is heated, substances such as carbon dioxide, carbon monoxide, and nitrogen oxides generated will flow above accommodating cavity 11. Exhaust gas discharge duct 21 is connected to top wall 13 of oven 100 to facilitate the discharge of substances such as carbon dioxide, carbon monoxide, and nitrogen oxides.

[0110] On the premise that one end of the exhaust gas discharge pipe 21 is connected to the top wall 13, one end of the exhaust gas discharge pipe 21 is connected to the top wall 13 at a position away from the door body. Exhausting the combustion products through the exhaust gas discharge pipe 21 at a position away from the door body can reduce the flow of combustion products toward the door body, thereby reducing the harm of the combustion products to the user.

[0111] like Figure 11 As shown, Figure 11 This is a schematic structural diagram of the exhaust gas discharge pipe 21 provided in an embodiment of the present application.

[0112] In a possible embodiment, the exhaust gas discharge pipe 21 includes an air inlet 211 and an exhaust port 212, wherein the air inlet 211 is connected to the inner container 1 (see Figure 10 ) is connected, the exhaust port 212 is located at one end of the exhaust gas discharge pipe 21 away from the air inlet 211, and the cross-sectional area of ​​the exhaust port 212 is greater than or equal to the cross-sectional area of ​​the air inlet 211.

[0113] The air inlet 211 of the exhaust gas discharge pipe 21 is connected to the inner tank 1. During the heating process, the air volume in the accommodating cavity 11 is fixed, the temperature rises, and the air pressure rises accordingly. The air pressure on the exhaust port 212 side is connected to the atmospheric pressure, and the air pressure range on the exhaust port 212 side is stable. The air pressure on the air inlet 211 side is greater than the air pressure on the exhaust port 212 side. Under the action of air pressure, the air is discharged through the exhaust gas discharge pipe 21.

[0114] For example, the cross-sectional area of ​​the exhaust port 212 is greater than or equal to the cross-sectional area of ​​the intake port 211. This allows air or exhaust gas to be discharged smoothly during the exhaust process. It also reduces any whistling or abnormal noise caused by pressure differences during the exhaust process.

[0115] Continue to see Figure 3In one possible embodiment, the exhaust gas discharge pipe 21 is detachably connected to the inner tank 1.

[0116] For example, the exhaust gas discharge pipe 21 and the inner liner 1 can be connected by one of the following connection methods: bolt connection, clamping connection, plug-in connection, lock connection, magnetic connection, etc.

[0117] The detachable connection between the exhaust gas discharge pipe 21 and the inner tank 1 is convenient for regular inspection and reduces the difficulty of cleaning and maintenance, so that the user can inspect and clean the interior of the exhaust gas discharge pipe 21 to ensure normal use.

[0118] In addition, when the pipeline layout needs to be adjusted, the exhaust gas exhaust pipe 21 can be disassembled again and then reconnected to other positions of the inner pot 1 to complete the reconfiguration, thereby improving the adaptability of the oven 100.

[0119] Continue to see Figure 4 The present application provides a cooking all-in-one machine 200 further including a cooking stove 300, which is located above the oven 100 and is connected to the oven 100. The oven 100 and the cooking stove 300 can operate independently.

[0120] For example, the oven 100 and the cooking stove may be connected in a detachable manner, or the cooking all-in-one machine 200 includes a housing, and the cooking stove 300 and the oven 100 are both located inside the housing.

[0121] The cooking stove 300 may be at least one of the following types of stoves: a gas stove, an electromagnetic stove, an electric stove, a charcoal stove, a biomass stove, and the like.

[0122] like Figure 12 As shown, Figure 12 This is one of the schematic diagrams of the position of the exhaust port 212 provided in the embodiment of the present application.

[0123] In a possible embodiment, the exhaust gas discharge structure 2 (see Figure 11 ) The end away from the inner pot 1 is located at a position of the cooking stove 300 away from the oven 100, and the end of the exhaust gas discharge structure 2 away from the inner pot 1 is an exhaust port 212.

[0124] The end of the exhaust gas discharge structure 2 away from the inner container 1 is located outside the oven 100. The exhaust gas discharge structure 2 discharges the combustion products outside the oven 100, reducing the probability of the combustion products accumulating inside the oven 100.

[0125] Exemplarily, the all-in-one cooking appliance 200 also includes a ventilation duct that connects the oven 100 and other cooking devices and is used to exhaust exhaust gases generated during the cooking process. The exhaust gas discharge structure 2 is connected to the ventilation duct at the end away from the inner pot 1. When the appliance is in operation, combustion products in the oven 100 are discharged into the ventilation duct through the exhaust gas discharge structure and then discharged through the ventilation duct.

[0126] In this way, the waste gas generated during cooking can be discharged in a centralized manner. The waste gas discharge pipe is connected to the ventilation channel, which can shorten the length of the waste gas discharge pipe and reduce the material used for the waste gas discharge pipe.

[0127] In one possible embodiment, the cooking appliance 200 includes a range hood located on the side of the cooking hob 300 facing away from the oven 100, which is used to exhaust fumes generated during cooking to the outside. The exhaust gas discharge structure 2 discharges combustion products to the side of the cooking hob 300 facing away from the oven 100, facilitating their removal by the range hood and reducing the risk of harm to users.

[0128] like Figure 13 As shown, Figure 13 This is the second schematic diagram of the position of the exhaust port 212 provided in the embodiment of the present application.

[0129] In a possible embodiment, the cooking stove 300 includes at least one heating element 301, which is used to provide heat. The exhaust gas discharge structure 2 is away from the inner pot 1 (see Figure 3 ) is located on the side of the heating element 301 away from the user, and the end of the exhaust gas discharge structure 2 away from the inner tank 1 is the exhaust port 212. Figure 13 In , M represents the user.

[0130] It should be noted that when the cooking appliance 200 is placed on the ground, the user needs to face the cooking appliance 200 during cooking to facilitate operation. In one application scenario, the heating element 301 is located in front of the user. When the user is using the oven 100, the end of the exhaust structure 2 away from the inner pot 1 is located on the side of the heating element 301 facing away from the user. This allows the combustion products in the oven 100 to be discharged to the side of the heating element 301 facing away from the user, reducing the harm caused by the combustion products to the user.

[0131] When a user uses the cooking stove 300, the user generally places the cooking pot on top of the heating element 301. At this time, the pot will block the combustion products from being discharged to the side of the heating element 301 away from the user and then scattering toward the user, thereby reducing the harm caused by the combustion products to the user.

[0132] Exemplarily, the heating element 301 is a burner of a gas stove, a heating wire of an electric stove, a coil of an electromagnetic cooker, or a heating element in a ceramic stove, and the heating element 301 is used to provide heat for cooking.

[0133] In a possible embodiment, the cooking machine 200 also includes a display panel, which is located on the side of the cooking stove 300 facing away from the oven 100, and the display panel is located on the side of the heating element 301 facing away from the user. The display panel is connected to the cooking stove 300, and the end of the exhaust gas discharge structure 2 away from the inner pot 1 is connected to the display panel.

[0134] In one possible embodiment, the cooking machine 200 further includes a back panel 302, which is located on the side of the cooking machine 200 facing away from the user. The back panel 302 is connected to the cooking machine 200, and the end of the exhaust gas discharge structure 2 away from the inner pot 1 is connected to the back panel 302 for discharging combustion products to the side of the back panel 302 facing away from the cooking machine 200.

[0135] In this way, the combustion products are discharged from the cooking machine 200 and away from the user, thereby reducing the harm of the combustion products to the user.
