Abstract
Description
[0001] This application claims priority to patent application filed with the State Intellectual Property Office on December 23, 2024, application number 202411906681.8, entitled "Cooking Equipment", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of kitchen appliances technology, and in particular to an exhaust system, cooking equipment and integrated stove. Background Technology
[0003] Steam ovens and steam oven components in integrated stoves are kitchen appliances that combine steaming and baking functions.
[0004] When cooking equipment such as steam ovens and steam oven components in integrated stoves activate the steam function mode, water vapor is introduced into the inner liner. After the water vapor is delivered into the inner liner, the gas inside the inner liner is discharged into the exhaust pipe through the air outlet on the inner liner. Finally, the exhaust pipe discharges the gas into the atmosphere, completing the gas discharge process.
[0005] During or after the venting process, condensation will be generated in the vent pipe. A large amount of condensation will flow into the inner pot through the vent. Under the influence of gravity, the condensation will easily splash onto the food inside the inner pot, causing the food to absorb the condensation unevenly and have inconsistent moisture content, thus affecting the subsequent cooking effect and taste of the food. Summary of the Invention
[0006] This application provides an exhaust assembly, cooking equipment, and integrated stove to solve the technical problem that a large amount of condensate will flow into the inner liner through the air outlet during or after the exhaust process of existing cooking equipment.
[0007] A first aspect of this application provides an exhaust assembly, including:
[0008] A water collection tank is used to install on cooking equipment;
[0009] The exhaust pipe has a first port and a second port located below the first port. A steam inlet is provided on the side wall of the exhaust pipe, and the steam inlet is located between the first port and the second port. The steam inlet is used to communicate with the air outlet of the inner pot of the cooking device. The first port is used to communicate with the outside of the cooking device, so that the gas in the inner pot is discharged from the air outlet through the steam inlet and the first port in sequence. The second port is connected to the water collection tank, so that the condensate in the exhaust pipe is discharged into the water collection tank through the second port.
[0010] In one possible implementation, an air inlet pipe is also included, through which the steam inlet is connected to the air outlet, and the height of the end of the air inlet pipe near the air outlet is higher than the height of the end of the air inlet pipe away from the air outlet, so that water in the air inlet pipe flows into the exhaust pipe.
[0011] In one possible implementation, the exhaust pipe includes a first exhaust section, an intermediate section, and a second exhaust section connected in sequence. The end of the first exhaust section away from the intermediate section forms the first port, and the first exhaust section is provided with at least one bend. The steam inlet is located on the intermediate section, and the end of the second exhaust section away from the intermediate section forms the second port.
[0012] In one possible implementation, a switching valve and a return water pipe are also included, with the second port connected to one end of the switching valve and the other end of the switching valve connected to the water collection tank via the return water pipe.
[0013] In one possible implementation, a fixing plate is also included, through which the switch valve is fixed to the cooking equipment, and the second port, the switch valve, the return pipe, and the water collection tank are arranged sequentially from top to bottom.
[0014] One possible implementation also includes:
[0015] An air supply device, for installation on the cooking equipment;
[0016] A gas heating module has an air inlet and an air outlet. The air inlet is connected to the air supply device, and the air outlet is connected to the inner liner. The gas heating module is used to heat the air input by the air supply device to form hot air and guide the hot air into the inner liner.
[0017] A humidity sensor is used to detect the humidity inside the inner liner;
[0018] The controller is electrically connected to the air supply device, the gas heating module, and the humidity sensor, respectively.
[0019] When the humidity inside the inner liner is greater than or equal to a preset value, the controller controls the air supply device and the gas heating module to start, so as to input the hot air into the inner liner and drive the gas inside the inner liner to be discharged from the air outlet of the inner liner.
[0020] When the humidity inside the inner liner is less than a preset value, the controller shuts down the air supply device and the gas heating module.
[0021] In one possible implementation, the gas heating module includes a ventilation housing and a heating element. The ventilation housing is disposed on the cooking device and has a ventilation channel. The two ends of the ventilation channel form the air inlet and the air outlet, respectively. The heating element is electrically connected to the controller and is disposed within the ventilation channel. The heating element is used to heat the air within the ventilation channel.
[0022] In one possible implementation, the heating component includes a heating element and a plurality of heat-conducting plates. The heating element is provided with a plurality of heat-conducting plates at intervals. The heating element is used to heat the heat-conducting plates. A heating channel is formed between two adjacent heat-conducting plates. One end of the heating channel is connected to the air inlet end, and the other end of the heating channel is connected to the air outlet end.
[0023] In one possible implementation, the ventilation channel includes an air inlet section, a middle section, and an air outlet section connected in sequence. The air inlet section is provided with an air inlet end, and the air outlet section is provided with an air outlet end. The diameter of the middle section is larger than the diameters of the air inlet section and the air outlet section, respectively, and the heat-conducting plates are arranged sequentially and spaced apart from the top wall of the middle section to the bottom wall of the middle section.
[0024] A second aspect of this application provides a cooking device, including a shell and an inner pot, the inner pot being disposed within the shell, the inner pot having an air outlet, and further including an exhaust assembly as described in any one of the above claims, the water collection tank of the exhaust assembly being disposed on the shell, and the steam inlet of the exhaust pipe of the exhaust assembly being connected to the air outlet.
[0025] A third aspect of this application provides an integrated stove, including an integrated stove body and the aforementioned cooking device, wherein the cooking device is disposed on the integrated stove body.
[0026] This application provides an exhaust assembly, cooking equipment, and integrated stove. The exhaust assembly includes a water collection tank and an exhaust pipe. The water collection tank is used to install on the cooking equipment. The exhaust pipe has a first port and a second port located below the first port. A steam inlet is provided on the side wall of the exhaust pipe. The steam inlet is used to communicate with the air outlet of the inner liner of the cooking equipment. The first port is used to communicate with the atmosphere, and the second port is used to communicate with the water collection tank. In the exhaust assembly of this application, the steam inlet on the side wall of the exhaust pipe is connected to the air outlet of the inner pot of the cooking equipment. The gas in the inner pot enters the exhaust pipe through the air outlet. Since the second port of the exhaust pipe is located below the first port, the gas will be discharged into the atmosphere from the first port. When condensation forms in the exhaust pipe, the condensation will flow down the exhaust pipe from top to bottom due to gravity and flow into the water collection tank from the second port. That is, the condensation in the exhaust pipe will flow into the water collection tank through the second port, avoiding the condensation in the exhaust pipe from flowing into the inner pot. This solves the technical problem of existing cooking equipment where a large amount of condensation flows into the inner pot through the air outlet during or after exhaust. This prevents the condensation from flowing back into the inner pot and causing uneven heating of the food, thus ensuring that the food has a consistent appearance and taste. It also improves the cooking effect and taste of the food cooked in the inner pot. In addition, it reduces the amount of residual water at the bottom of the inner pot, reduces the difficulty of cleaning, and improves the user experience. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0041] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0042] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0043] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.
[0044] Steam ovens and steam oven components in integrated stoves are kitchen appliances that combine steaming and baking functions.
[0045] Currently available steam and oven cooking equipment generates steam in its internal cavity, regardless of whether it's in steaming or baking mode. As the steam content inside the cavity increases with continuous heating, the pressure rises. Because hot steam has a low density, it gradually rises and accumulates at the top of the cavity before being expelled through the lower-pressure vent. During this expulsion process, because the temperature of the external exhaust pipe is lower than the internal cavity temperature, the steam releases heat and condenses, producing condensate. This condensate accumulates, increasing in volume and weight, overcoming the pressure of the expelled steam, and flows back into the cavity. As this condensate flows back from top to bottom, its increased potential energy due to gravity causes it to splash onto the food inside the cavity. This uneven heating and inconsistent moisture content after the food absorbs the condensate results in some foods having a poor appearance and taste after cooking; for example, steamed buns may partially collapse, or small cakes may become unsaturated, affecting the subsequent cooking results and texture. Additionally, some condensate with insufficient gravitational potential energy slides down the cavity wall and accumulates at the bottom of the cavity, resulting in excessive residual water and time-consuming cleaning. All of these factors contribute to a poor user experience.
[0046] To address the technical problem of large amounts of condensate flowing into the inner liner of existing cooking equipment during or after venting, this application proposes an exhaust assembly, a cooking device, and an integrated stove. The exhaust assembly includes a water collection tank and an exhaust pipe. The water collection tank is installed on the cooking device. The exhaust pipe has a first port and a second port located below the first port. A steam inlet is provided on the side wall of the exhaust pipe, located between the first port and the second port. The steam inlet is used to communicate with the air outlet of the inner liner of the cooking device. The first port is used to communicate with the atmosphere, so that the gas inside the inner liner is discharged into the atmosphere from the air outlet through the steam inlet and the first port in sequence. The second port is connected to the water collection tank, so that the condensate in the exhaust pipe is discharged into the water collection tank through the second port.
[0047] In the exhaust assembly of this application, the steam inlet on the side wall of the exhaust pipe is connected to the air outlet of the inner pot of the cooking equipment. The gas in the inner pot enters the exhaust pipe through the air outlet. Since the second port of the exhaust pipe is located below the first port, the gas will be discharged into the atmosphere from the first port. When condensation forms in the exhaust pipe, the condensation will flow down the exhaust pipe from top to bottom due to gravity and flow into the water collection tank from the second port. That is, the condensation in the exhaust pipe will flow into the water collection tank through the second port, avoiding the condensation in the exhaust pipe from flowing into the inner pot. This solves the technical problem of existing cooking equipment where a large amount of condensation flows into the inner pot through the air outlet during or after exhaust. This prevents the condensation from flowing back into the inner pot and causing uneven heating of the food, thus ensuring that the food has a consistent appearance and taste. It also improves the cooking effect and taste of the food cooked in the inner pot. In addition, it reduces the amount of residual water at the bottom of the inner pot, reduces the difficulty of cleaning, and improves the user experience.
[0048] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0050] In the embodiments of this application, reference is made to Figures 1 to 4 As shown, an embodiment of this application provides an exhaust assembly, including a water collection tank 100 and an exhaust pipe 200. The water collection tank 100 is used to be installed on a cooking device 10. The exhaust pipe 200 has a first port 210 and a second port 220 located below the first port 210. A steam inlet 230 is provided on the side wall of the exhaust pipe 200, and the steam inlet 230 is located between the first port 210 and the second port 220. The steam inlet 230 is used to communicate with the air outlet 31 of the inner pot 30 of the cooking device 10. The first port 210 is used to communicate with the outside of the cooking device 10, so that the gas in the inner pot 30 is discharged from the cooking device 10 from the air outlet 31 through the steam inlet 230 and the first port 210 in sequence. The second port 220 is communicated with the water collection tank 100, so that the condensate in the exhaust pipe 200 is discharged into the water collection tank 100 through the second port 220.
[0051] In the exhaust assembly of this application embodiment, the water collection tank 100 can be disposed below the front side of the cooking device 10 to collect condensate in the exhaust pipe 200. The shape of the water collection tank 100 can be set as a long strip to increase the volume of the water collection tank 100.
[0052] The exhaust pipe 200 has a first port 210 and a second port 220. The first port 210 is above the second port 220. When there is condensate in the exhaust pipe 200, the condensate will be discharged from the second port 220 due to its weight.
[0053] A steam inlet 230 is provided on the side wall of the exhaust pipe 200. The steam inlet 230 is located between the first port 210 and the second port 220, that is, the steam inlet 230 is located below the first port 210 and above the second port 220.
[0054] In the exhaust assembly of this application, the steam inlet 230 on the side wall of the exhaust pipe 200 is connected to the air outlet 31 of the inner liner 30 of the cooking appliance 10. Gas inside the inner liner 30 enters the exhaust pipe 200 through the air outlet 31. Since the second port 220 of the exhaust pipe 200 is located below the first port 210, the gas will be discharged into the atmosphere from the first port 210. When condensate forms inside the exhaust pipe 200, the condensate will flow down the exhaust pipe 200 due to gravity, flowing from top to bottom and into the water collection tank 100 from the second port 220. In other words, the condensate inside the exhaust pipe 200 is cooled. Condensate will flow into the water collection tank 100 through the second port 220, preventing condensate in the exhaust pipe 200 from flowing into the inner pot 30. This solves the technical problem of existing cooking equipment 10 where a large amount of condensate flows into the inner pot 30 through the air outlet 31 during or after exhaust. This prevents condensate from flowing back into the inner pot 30 and causing uneven heating of the food, thus ensuring that the food's appearance and taste are consistent. It also improves the cooking effect and taste of the food cooked in the inner pot 30. In addition, it reduces the amount of residual water at the bottom of the inner pot 30, making cleaning easier and improving the user experience.
[0055] In other embodiments, refer to Figure 3 and Figure 4 As shown, it also includes an air inlet pipe 300, and a steam inlet 230 is connected to an air outlet 31 through the air inlet pipe 300. The height of the end of the air inlet pipe 300 near the air outlet 31 is higher than the height of the end of the air inlet pipe 300 away from the air outlet 31, so that the water in the air inlet pipe 300 flows into the exhaust pipe 200.
[0056] In this embodiment, the air outlet 31 of the inner liner 30 is connected to the steam inlet 230 of the exhaust pipe 200 through the air inlet pipe 300. Since the height of the end of the air inlet pipe 300 near the air outlet 31 is higher than the height of the end of the air inlet pipe 300 away from the air outlet 31, when there is condensate in the air inlet pipe 300, the condensate will flow from the end of the air inlet pipe 300 near the air outlet 31 to the end of the air inlet pipe 300 away from the air outlet 31 due to gravity, and finally flow into the exhaust pipe 200. By setting the air inlet pipe 300, the condensate in the exhaust pipe 200 can be further prevented from flowing into the inner liner 30.
[0057] In some embodiments, reference is made to Figure 3 As shown, the exhaust pipe 200 includes a first exhaust section 240, an intermediate section 250 and a second exhaust section 260 connected in sequence. The end of the first exhaust section 240 away from the intermediate section 250 forms a first port 210, and the first exhaust section 240 is provided with at least one bend section 241. The steam inlet 230 is provided on the intermediate section 250, and the end of the second exhaust section 260 away from the intermediate section 250 forms a second port 220.
[0058] In this embodiment, since at least one bend 241 is provided on the first exhaust section 240, water vapor can easily condense at the bend 241, thereby reducing the amount of water vapor discharged.
[0059] In another embodiment, reference Figure 4 As shown, it also includes a switch valve 400 and a return water pipe 500. The second port 220 is connected to one end of the switch valve 400, and the other end of the switch valve 400 is connected to the water collection tank 100 through the return water pipe 500.
[0060] In this embodiment, the discharge of the exhaust pipe 200 is controlled by setting a switch valve 400, which ensures that the condensate in the exhaust pipe 200 can be discharged into the water collection tank 100 at any time by closing or opening the valve.
[0061] It should be noted that the switching valve 400 can be a solenoid valve, which can be electrically connected to the controller 40 on the cooking device 10, and the controller 40 can be used to open or close the switching valve 400.
[0062] In some embodiments, reference is made to Figure 1 and Figure 8 As shown, it also includes a fixing plate 600, and the switch valve 400 is fixed to the cooking device 10 through the fixing plate 600. The second port 220, the switch valve 400, the return water pipe 500 and the water collection tank 100 are arranged in order from top to bottom.
[0063] It should be noted that "from top to bottom" refers to the height of the cooking equipment 10.
[0064] In this embodiment, the switch valve 400 is fixed to the cooking device 10 by the fixing plate 600. The fixing plate 600 plays a role in fixing and positioning the switch valve 400, so that the switch valve 400 is located between the second port 220 and the return water pipe 500.
[0065] In one embodiment, reference is made to... Figure 5 and Figure 9 As shown, it also includes an air supply device 700, a gas heating module 800, a humidity sensor 900, and a controller 40. The air supply device 700 is installed on the cooking equipment 10. The gas heating module 800 has an air inlet 810 and an air outlet 820. The air inlet 810 is connected to the air supply device 700, and the air outlet 820 is connected to the inner liner 30. The gas heating module 800 heats the air input by the air supply device 700 to form hot air and guides the hot air into the inner liner 30. The humidity sensor 900 is used to detect the humidity inside the inner liner 30. The controller 40 is electrically connected to the air supply device 700, the gas heating module 800, and the humidity sensor 900.
[0066] When the humidity inside the inner liner 30 is greater than or equal to a preset value, the controller 40 controls the air supply device 700 and the gas heating module 800 to start, so as to input hot air into the inner liner 30 and drive the gas inside the inner liner 30 to be discharged to the air outlet 31 of the inner liner 30; when the humidity inside the inner liner 30 is less than the preset value, the controller 40 controls the air supply device 700 and the gas heating module 800 to shut down.
[0067] The air supply device 700 in this embodiment can be an exhaust fan, a fan, etc., and the air supply device 700 supplies air to the air inlet 810 of the gas heating module 800.
[0068] The humidity sensor 900 measures ambient humidity by sensing changes in water vapor content within the inner liner 30 and converting this information into an electrical signal. Based on different measurement principles, the humidity sensor 900 can be categorized into several types, including resistive, capacitive, thermistor, dew point, optical, and semiconductor types.
[0069] The controller 40 can be an electronic chip such as a microcontroller unit (MCU) or a central processing unit (CPU).
[0070] In this embodiment, after the steaming function mode of the cooking device 10 is completed, the humidity sensor 900 detects the humidity inside the inner pot 30 of the cooking device 10. The humidity sensor 900 transmits the detected humidity signal inside the inner pot 30 to the controller 40. When the humidity inside the inner pot 30 is greater than or equal to a preset value, the controller 40 controls the air supply device 700 and the gas heating module 800 to start. After the air supply device 700 delivers air to the gas heating module 800, the gas heating module 800 heats the air delivered by the air supply device 700 to form hot air. Finally, the hot air is delivered to the inner pot 30. When a large amount of hot air is delivered to the inner pot 30, the pressure inside the inner pot 30 increases, thereby forcing the gas inside the inner pot 30 to be discharged from the air outlet 31 of the inner pot 30, and causing the steam inside the inner pot 30 to be discharged from the air outlet 31, thereby reducing the humidity inside the inner pot 30.
[0071] When the humidity inside the inner liner 30 drops below the preset value, the controller 40 controls the air supply device 700 and the gas heating module 800 to shut down, thereby ensuring that the humidity inside the inner liner 30 is less than or equal to the preset value, reducing the steam inside the inner liner 30, ensuring the color and taste of the food, and improving the cooking effect of the cooking equipment 10.
[0072] It should be noted that the preset value can be customized. The smaller the preset value, the lower the humidity inside the 3030 inner tank can be.
[0073] In some possible embodiments, refer to Figure 5 and Figure 6 As shown, the gas heating module 800 includes a ventilation housing 830 and a heating element 840. The ventilation housing 830 is used to install on the cooking device 10. A ventilation channel 1000 is provided inside the ventilation housing 830. An air inlet 810 and an air outlet 820 are formed at both ends of the ventilation channel 1000, respectively. The heating element 840 is electrically connected to the controller 40. The heating element 840 is installed inside the ventilation channel 1000 and is used to heat the air inside the ventilation channel 1000.
[0074] In this embodiment, the heating element 840 can be a PTC heating element, heating tube, etc. A PTC heating element, also known as a PTC heating body or PTC heater, is a heating element composed of a PTC (Positive Temperature Coefficient) ceramic heating element and heat dissipation materials such as aluminum tubes.
[0075] In other possible embodiments, refer to Figure 6 and Figure 7 As shown, the heating assembly 840 includes a heating element 841 and a plurality of heat-conducting plates 842. The heating element 841 is provided with a plurality of heat-conducting plates 842 at intervals. The heating element 841 is used to heat the heat-conducting plates 842. A heating channel 1100 is formed between two adjacent heat-conducting plates 842. One end of the heating channel 1100 is connected to the air inlet 810, and the other end of the heating channel 1100 is connected to the air outlet 820.
[0076] In this embodiment, the air entering from the air inlet 810 is diverted to multiple heating channels 1100, and the air is heated through the multiple heating channels 1100, thereby improving the heating efficiency and heating effect of the air.
[0077] In one possible embodiment, the ventilation channel 1000 includes an air inlet section 1010, a middle section 1020 and an air outlet section 1030 connected in sequence. The air inlet section 1010 is provided with an air inlet end 810, and the air outlet section 1030 is provided with an air outlet end 820. The diameter of the middle section 1020 is larger than the diameters of the air inlet section 1010 and the air outlet section 1030, respectively. Each heat conduction plate 842 is arranged sequentially and spaced apart from the top wall of the middle section 1020 to the bottom wall of the middle section 1020.
[0078] In this embodiment, since the diameter of the middle section 1020 is larger than the diameters of the air inlet section 1010 and the air outlet section 1030, the heating volume of the air entering from the air inlet end 810 is increased, which further improves the heating efficiency and heating effect of the air.
[0079] Furthermore, refer to Figure 5As shown, the gas heating module 800 also includes a temperature control switch 850, which is mounted on the ventilation housing 830 and connected to the heating element 840. The temperature control switch 850 is used to control the opening and closing of the heating element 840.
[0080] The 850 temperature control switch, also known as a temperature-controlled switch or thermal switch, is a device that connects or disconnects a circuit based on temperature changes, thereby controlling the operating status of electrical appliances or systems. Its core component is a thermistor, typically composed of two metal strips with different coefficients of thermal expansion. When the temperature changes, the different coefficients of thermal expansion cause the strips to bend, which in turn alters the contact state of the switch, thus controlling the circuit's on / off state.
[0081] The second aspect of this application provides a cooking device 10, including a housing 20 and an inner pot 30. The inner pot 30 is disposed inside the housing 20 and has an air outlet 31. It also includes an exhaust assembly of any of the above embodiments. The water collection tank 100 of the exhaust assembly is disposed on the housing 20, and the steam inlet 230 of the exhaust pipe 200 of the exhaust assembly is connected to the air outlet 31.
[0082] The cooking device 10 of this application embodiment is equipped with an exhaust assembly, which includes a water collection tank 100 and an exhaust pipe 200. The water collection tank 100 is installed on the cooking device 10. The exhaust pipe 200 has a first port 210 and a second port 220 located below the first port 210. A steam inlet 230 is provided on the side wall of the exhaust pipe 200, and the steam inlet 230 is located between the first port 210 and the second port 220. The steam inlet 230 is used to communicate with the air outlet 31 of the inner pot 30 of the cooking device 10. The first port 210 is used to communicate with the atmosphere, so that the gas in the inner pot 30 is discharged into the atmosphere from the air outlet 31 through the steam inlet 230 and the first port 210 in sequence. The second port 220 is connected to the water collection tank 100, so that the condensate in the exhaust pipe 200 is discharged into the water collection tank 100 through the second port 220.
[0083] In the cooking device 10 of this application, by connecting the steam inlet 230 on the side wall of the exhaust pipe 200 to the air outlet 31 of the inner liner 30 of the cooking device 10, the gas inside the inner liner 30 enters the exhaust pipe 200 through the air outlet 31. Since the second port 220 of the exhaust pipe 200 is located below the first port 210, the gas will be discharged into the atmosphere from the first port 210. When condensate forms inside the exhaust pipe 200, the condensate will flow down the exhaust pipe 200 from top to bottom due to gravity, flowing from the second port 220 into the water collection tank 100, i.e., inside the exhaust pipe 200. Condensate will flow into the water collection tank 100 through the second port 220, preventing condensate in the exhaust pipe 200 from flowing into the inner pot 30. This solves the technical problem of existing cooking equipment 10 where a large amount of condensate flows into the inner pot 30 through the air outlet 31 during or after exhaust. This prevents condensate from flowing back into the inner pot 30 and causing uneven heating of the food, thus ensuring that the food's appearance and taste are consistent. It also improves the cooking effect and taste of the food cooked in the inner pot 30. In addition, it reduces the amount of residual water at the bottom of the inner pot 30, making cleaning easier and improving the user experience.
[0084] A third aspect of this application provides an integrated stove, including an integrated stove body and the aforementioned cooking device 10, wherein the cooking device 10 is disposed on the integrated stove body.
[0085] Since the integrated stove provided in this application includes the cooking device 10 of this application embodiment, the cooking device 10 of the integrated stove in this application avoids the condensate in the exhaust pipe 200 from flowing into the inner tank 30. This solves the technical problem that a large amount of condensate will flow into the inner tank 30 through the air outlet 31 during or after the exhaust process of the existing cooking device 10. This prevents the condensate from flowing back into the inner tank 30 and causing uneven heating of the food, thereby ensuring that the appearance and taste of the food are consistent. This improves the cooking effect and taste of the food cooked in the inner tank 30. In addition, it reduces the amount of residual water at the bottom of the inner tank 30, reduces the difficulty of cleaning, and improves the user experience.
