The condensate from the exhaust pipe flows back into the inner cavity, where its high temperature evaporates.

[0045] Currently, smart appliances generate water vapor when the temperature changes, and this water vapor condenses into condensate. To prevent condensate from affecting the further operation of the smart appliance, the water vapor in the exhaust pipe is typically returned to the inner cavity of the appliance, where the condensate is heated at a high temperature. However, for smart cooking appliances, such as smart steam ovens, the condensate returning to the inner cavity from the exhaust pipe can affect cooking, especially for moisture-sensitive foods; furthermore, if the exhaust pipe is long, the risk of condensate remaining in the exhaust pipe is high. Therefore, to collect the naturally returning condensate in the exhaust pipe and to extract the condensate from the exhaust pipe, this application provides an exhaust pipe that includes a condensate collection device.

[0046] This embodiment provides an exhaust pipe for the steam discharge of a smart appliance. The steam generated by the smart appliance flows sequentially through a first exhaust pipe, a condensate collection device, and a second exhaust pipe before entering the inner liner of the smart appliance. The condensate collection device includes a collection component, a cover plate, and a drainage component. The collection component includes a liquid storage chamber for collecting condensate from the exhaust pipe. The cover plate is movably connected to the collection component and can close or open the channel. When the cover plate is closed, it can prevent condensate from flowing into the inner liner of the smart appliance. The drainage component is connected to the liquid storage chamber for draining the condensate from the liquid storage chamber.

[0047] Among them, reference Figure 1 , Figure 1 This is a schematic diagram of the exhaust pipe structure provided in this embodiment of the application. Steam generated by the smart appliance 100 flows sequentially through the first exhaust pipe 20, the condensate collection device 10, and the second exhaust pipe 30, entering the inner liner of the smart appliance 100. The first exhaust pipe 20 and the second exhaust pipe 30 are respectively connected to multiple smart components in the smart appliance 100. For example, the exhaust pipes connect a gas stove and a steam oven; the first exhaust pipe 20 connects to the gas stove in the smart appliance 100, and the second exhaust pipe 30 connects to the steam oven in the smart appliance 100.

[0048] Figure 2 This is a cross-sectional view of the condensate collection device provided in an embodiment of this application. (Reference) Figure 1 and Figure 2 The condensate collection device 10 is connected at both ends to the first exhaust pipe 20 and the second exhaust pipe 30, respectively, and is used to collect condensate in the first exhaust pipe 20. In the condensate collection device 10, condensate is collected by a collection assembly including a liquid storage chamber 11. The liquid storage chamber 11 is a water storage area formed by expanding the condensate collection device 10 based on the original size of the exhaust pipe. Its shape can be a circular ring as shown in the figure, or it can be a square ring. The shape of the liquid storage chamber 11 is not specifically limited here.

[0049] A cover plate 12 is installed in the inner pipe of the collecting component. When the smart appliance 100 is not working or at the initial stage of operation, the internal air pressure of the inner liner of the smart appliance 100 is low and insufficient to open the cover plate 12. At this time, the cover plate 12 is in the closed state, thereby closing the upper and lower channels in the exhaust pipe. After the smart appliance 100 has been working for a period of time, the internal air pressure of the inner liner of the smart appliance 100 increases. At this time, the cover plate 12 can be opened, thereby opening the upper and lower channels in the exhaust pipe. That is, the opening or closing of the cover plate 12 depends on the internal air pressure of the inner liner, which is mainly determined by the working state of the smart appliance 100.

[0050] The condensate collection device 10 also includes a drainage component 13, which is connected to the liquid storage chamber 11. A water level sensor is installed in the liquid storage chamber 11. When the water level sensor detects that the water level in the liquid storage chamber 11 has reached a preset level, it controls the opening of the drainage component 13 to drain the condensate stored in the liquid storage chamber 11, preventing the condensate from overflowing and flowing back into the inner tank. Furthermore, the drainage component 13 can be an externally connected lower connector that drains condensate while storing water in the liquid storage chamber 11, or it can be a device equipped with a water pump to drain the condensate from the liquid storage chamber 11 all at once; no specific limitation is made here.

[0051] In some embodiments, the collection assembly also includes a flow guiding structure for guiding condensate from the sidewall of the exhaust pipe into the reservoir.

[0052] The guide structure connects the first exhaust pipe and the condensate collection device. The diameter of the side of the guide structure connected to the condensate collection device exceeds the diameter of the side connected to the first exhaust pipe, so as to guide the condensate condensed on the side wall of the first exhaust pipe into the liquid storage chamber.

[0053] In some embodiments, the exhaust pipe further includes a heating assembly for evaporating condensate in the exhaust pipe.

[0054] After the condensate in the exhaust pipe is collected through the liquid storage chamber and drained through the drainage component, some condensate may still remain on the inner wall of the exhaust pipe. In this case, the heating component is needed to further evaporate the condensate in the exhaust pipe to prevent it from entering the inner liner and affecting food cooking. The heating component is generally located on the side near the inner liner and includes a hot air blower, a back heating element, and fan blades; for example, the back heating element and fan blades can be located inside the inner liner; the hot air blower can be located at the back of the inner liner.

[0055] This embodiment provides an exhaust pipe cleaning control method for cleaning the exhaust pipe of any of the first aspects described above; Figure 3 This is a flowchart of the exhaust pipe cleaning control method provided in an embodiment of this application. (Reference) Figure 3 The method includes:

[0056] Step S310: In response to the received cleaning instruction, determine whether the smart appliance is in cooking mode.

[0057] When cleaning the exhaust pipe, ensure the cleaning operation is performed when the smart appliance is not in operation to avoid interfering with normal cooking or creating safety hazards. If cooking is in progress, pause or postpone the cleaning process to prevent accidental drainage that could interrupt steam supply or cause equipment malfunction.

[0058] Step S320: When the smart appliance is not in cooking mode, obtain the condensate water level in the liquid storage chamber of the condensate water collection device.

[0059] The condensate collection device in the exhaust pipe collects condensate from the inner wall of the exhaust pipe through a storage chamber. A water level sensor is installed in the storage chamber to monitor the condensate level in real time, preventing overflow and subsequent flow of condensate into the inner tank of the smart appliance if the water level exceeds a preset level. If the water level is zero, no drainage is needed; if it is close to full, immediate action is required.

[0060] Step S330: Determine the drainage operation time of the drainage component in the condensate collection device based on the condensate water level; during the drainage operation time, control the drainage component to drain water.

[0061] Specifically, a mapping relationship between water level and drainage operation time can be established based on the structural parameters of the drainage components, thereby enabling on-demand drainage, improving efficiency, and saving energy. By controlling the opening of the drainage components, condensate in the exhaust pipe can be collected, and after the operation ends, the exhaust pipe is dried through the combined action of a hot air blower and a back heating pipe, preventing the exhaust pipe from becoming damp.

[0062] Furthermore, historical drainage data can be recorded to predict drainage needs for the next cleaning cycle.

[0063] Through the above steps, by installing a condensate collection component inside the exhaust pipe, the condensate adhering to the inner wall of the exhaust pipe is collected, and by installing a cover plate, the condensate is prevented from entering the inner liner; by installing a drainage component, the collected condensate is discharged, thus achieving the collection and discharge of condensate in the exhaust pipe, thereby achieving the cleaning of the exhaust pipe.

[0064] In some embodiments, the exhaust pipe cleaning control method further includes controlling the drainage component to drain water within a preset drainage time when the smart appliance is in cooking mode.

[0065] When the smart appliance is in cooking mode, the system detects that the water level in the storage chamber has reached the preset level. At this time, the condensate in the storage chamber is drained according to the preset drainage time to prevent the condensate from affecting the cooking of the smart appliance.

[0066] Furthermore, after operating for 10 minutes under the steam function of the smart appliance, the drainage component is controlled to drain water.

[0067] In some embodiments, the exhaust pipe cleaning control method further includes: acquiring the cooking state of the smart appliance before the cleaning command; the cooking state includes steaming and baking; when the cooking state is steaming, controlling the hot air blower and heating element in the heating assembly to operate simultaneously; when the cooking state is baking, controlling the hot air blower in the heating assembly to operate.

[0068] When the smart appliance is not in cooking mode, the method of obtaining the condensate level in the condensate collection chamber of the condensate collection device also includes: determining whether there is food inside the smart appliance when it is not in cooking mode; and obtaining the condensate level in the condensate collection chamber when there is no food inside the smart appliance.

[0069] Before receiving a cleaning command, the system first acquires the historical cooking status of the smart appliance prior to executing the command to ensure that subsequent cleaning operations can be adaptively adjusted according to actual usage. The cooking status includes, but is not limited to, steaming and baking. Steaming refers to the smart appliance's operating mode, which generates high-temperature steam by heating the water tank or directly introducing water, and uses the steam to heat or cook food. Typical characteristics include the steam generator operating and a significant increase in humidity within the cavity. Baking refers to the smart appliance's mode, which primarily relies on heating elements (such as upper and lower heating elements, or a rear heating element) and a hot air circulation system to dry-heat food, typically accompanied by a lower humidity environment and forced convection.

[0070] If the smart appliance's historical cooking mode is steaming, the hot air blower and heating element in the heating assembly will operate simultaneously, creating a combined heating environment of "humid heat + forced convection." This mode can further evaporate excess moisture remaining on the cavity walls and in the condensation channels. If the smart appliance's historical cooking mode is baking, the hot air blower will operate alone to achieve rapid ventilation and drying inside the cavity.

[0071] Furthermore, assuming the smart appliance is not currently in any cooking state, it is necessary to determine whether there is food inside. This involves detecting the presence of food within the cooking cavity of the smart appliance. This detection can be achieved in various ways, such as using a built-in camera to perform image recognition of the appliance's interior, using pressure sensors to monitor changes in the load on the inner pot, or analyzing user behavior to determine if the user manually canceled the task and opened the door to remove the food.

[0072] The condensate level in the condensate collection device is only checked when there is no food in the cooking cavity. This is to prevent the drainage or exhaust cleaning process from being accidentally activated when there is still food residue, thus avoiding food burning, smoke production, or other problems.

[0073] After drainage is completed, the system can also start the drying program and run the hot air blower continuously to ensure that the liquid storage chamber and exhaust pipe are completely dry and inhibit bacterial growth.

[0074] This embodiment provides a smart appliance, which includes a processor and the aforementioned exhaust pipe; the processor employs an exhaust pipe cleaning control method to clean the exhaust pipe in the smart appliance; the smart appliance is one of a smart oven, a smart steam oven, or a smart stove-steam oven.

[0075] The method embodiments provided in this example can be executed on a terminal, computer, or similar computing device. For example, they can run on a controller. Figure 4 This is a hardware structure block diagram of the terminal of the exhaust pipe cleaning control method provided in this embodiment. For example... Figure 4 As shown, a terminal may include one or more ( Figure 4 Only one is shown in the diagram. A processor 102 and a memory 104 for storing data are also included. The processor 102 may be, but is not limited to, a microprocessor (MCU) or a programmable logic device (FPGA). The terminal may also include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that… Figure 4 The structure shown is for illustrative purposes only and does not limit the structure of the terminal described above. For example, the terminal may also include components that are larger than... Figure 4 The more or fewer components shown, or having the same Figure 4 The different configurations shown are illustrated.

[0076] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the exhaust pipe cleaning control method in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0077] The transmission device 106 is used to receive or send data via a network. This network includes a wireless network provided by the terminal's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 can be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0078] The present embodiment will be described and explained below through specific examples.

[0079] Figure 5 This is a flowchart of a gas pipe cleaning control method for a stove-steam oven provided in this specific embodiment. For example... Figure 5 As shown, the gas pipe cleaning control method for stove steaming and baking includes the following steps:

[0080] When cleaning of the trachea is required, a cleaning request command is first received. This command can be triggered in three ways: 1. User input via button or voice. 2. Setting an automatic cleaning function, which automatically sends a cleaning command after cooking. 3. Automatically triggered when the water level in the condensate collection device's storage chamber reaches the preset pumping level.

[0081] Upon receiving a cleaning instruction, the system first needs to determine if the smart appliance is in cooking mode. If so, the water pump is turned on to drain the water, and after running for the set time, the pump is turned off to end the process. This logic is triggered during the cooking process because the water level in the storage chamber reaches the preset level. At this point, the condensate can be drained according to the program's set time, or the water can be drained at any time during cooking to prevent scale buildup in the storage chamber and the growth of bacteria.

[0082] If the smart appliance is not in cooking mode, the camera determines whether the food has been removed from the cavity. If the food has been removed, the subsequent condensate removal process continues. If the food has not been removed, no drainage is performed, and the process ends.

[0083] If the food in the cavity has been removed, the condensate level is detected using a water level sensor, and then, based on a preset relationship between the condensate level and the drainage operation time, the drainage operation time is determined using the condensate level. If the current drainage component is a water pump, the water pump operation time is calculated based on the condensate level.

[0084] Then, the water pump is turned on, and after the pump has run for the calculated time, it is turned off. At this point, the water vapor collected in the exhaust pipe is discharged. However, some condensate remains on the inner wall of the exhaust pipe and cannot condense into water droplets. In this case, the heating element is needed for further heating and evaporation.

[0085] Specifically, the system first determines whether the pre-cleaning program is in steam or baking mode. If it is in steam mode, the hot air blower and back heating element operate simultaneously to achieve rapid drying and cleaning in a humid environment. After the set time A, the back heating element and hot air blower are turned off, ending this stage of heating and evaporation.

[0086] If it is in baking mode, only the hot air blower will be controlled to run, using forced convection to dry any residual grease and particles inside the cavity. After running for the set time B, the hot air blower will be turned off, ending this stage of heating and evaporation.

[0087] Furthermore, the set duration A exceeds the set duration B.

[0088] Through the above process, after receiving a cleaning command, the smart appliance safely and efficiently drains condensate and performs subsequent drying and cleaning operations. By judging the current cooking status, the condition of the food inside the cavity, and the previous operating mode, it can adaptively adjust the drainage and drying strategies, improving user experience and equipment maintenance efficiency.

[0089] It should be noted that the steps shown in the above process or in the flowchart of the accompanying figures can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
