[0052] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0053] like Figure 1 As shown, in some embodiments of the present application, a steaming and baking device 10 is provided, comprising an inner pot 11, a steam generating device, a liquid storage tank and a waste liquid storage device.

[0054] The steam generating device is used to prepare the first solution into steam, and the steam is used to create a steaming and baking environment in the inner pot 11. The first solution can be clean water.

[0055] The liquid storage tank can be selectively connected to the steam generating device. For example, in some cases, the steaming and baking device 10 also includes a first pumping device, and the liquid in the liquid storage tank can be pumped into the steam generating device by the first pumping device. Therefore, the connection relationship between the liquid storage tank and the steam generating device can be controlled by controlling the state of the first pumping device. When the first pumping device is started, the liquid storage tank is connected to the steam generating device. When the first pumping device is turned off, the connection between the liquid storage tank and the steam generating device is cut off.

[0056] The waste liquid storage device can be selectively connected to the steam generating device. Similarly, in some cases, the steaming and baking device 10 also includes a second pumping device, which can pump the liquid in the steam generating device into the waste liquid storage device. Therefore, the connection relationship between the waste liquid storage device and the steam generating device can be controlled by controlling the state of the second pumping device. When the second pumping device is started, the waste liquid storage device is connected to the steam generating device. When the second pumping device is turned off, the waste liquid storage device is cut off from the steam generating device.

[0057] A detachable grease pan 12 is provided below the bottom wall of the inner pot 11. The grease pan 12 can be removed from the steaming and baking device 10 to dump out the dirt contained therein.

[0058] In some other embodiments of the present application, a method for descaling a steam-bake device 10 is provided, which is applied to the steam-bake device 10, such as Figure 2 As shown, the descaling method includes:

[0059] In response to the descaling instruction, the steaming and baking device 10 is controlled to enter a descaling working mode, wherein the descaling working mode includes a cleaning process and a rinsing process;

[0060] The cleaning process includes:

[0061] The second solution stored in the liquid storage tank is input into the steam generating device for cleaning, wherein the second solution is a cleaning solution containing a descaling agent; and the waste liquid generated by the cleaning process is collected into the waste liquid storage device;

[0062] The flushing process includes:

[0063] The third solution stored in the liquid storage tank is input into the steam generating device for flushing treatment, and the third solution is different from the second solution; the waste liquid generated by the flushing treatment is collected in the grease pan 12.

[0064] The first solution and the third solution may be the same or different.

[0065] The waste liquid generated by the cleaning process contains detached dirt and descaling agents, etc. The amount of waste liquid at this stage is relatively large, so it is collected in the waste liquid storage device. The amount of waste liquid generated by the flushing process is relatively small, and the waste liquid generated by the flushing process is relatively clean, so it can be collected in the grease pan 12. After the descaling is completed, the grease pan 12 can be removed and the waste liquid therein can be poured out. By classifying and processing the waste liquid at different stages in this way, the number of times the waste liquid flows to the waste liquid storage device is reduced, thereby minimizing the probability of clogging of components such as pipes or valve bodies used to introduce waste liquid into the waste liquid storage device.

[0066] Specifically, in some embodiments, the step of inputting the second solution stored in the liquid storage tank into the steam generating device includes:

[0067] Starting the first pumping device to pump the second solution stored in the liquid storage tank to the steam generating device;

[0068] The step of collecting the waste liquid generated by the cleaning process into the waste liquid storage device comprises:

[0069] The second pumping device is started to pump the waste liquid treated by cleaning in the steam generating device into the waste liquid storage device.

[0070] If a pipeline is provided between the liquid storage tank and the steam generating device, the first pumping device can be provided on the pipeline. When the first pumping device is in a closed state, the pipeline is cut off. When the first pumping device is started, the pipeline is connected, and the first pumping device can provide power so that the liquid in the liquid storage tank can flow from the pipeline to the steam generating device.

[0071] If a pipeline is provided between the steam generating device and the waste liquid storage device, the second pumping device can be provided on the pipeline. When the second pumping device is in a closed state, the pipeline is cut off. When the second pumping device is started, the pipeline is connected, and the second pumping device can provide power so that the waste liquid in the steam generating device can flow from the pipeline to the waste liquid storage device.

[0072] Similarly, in some embodiments, the step of inputting the third solution stored in the liquid storage tank into the steam generating device includes:

[0073] The first pumping device is started to pump the third solution stored in the liquid storage tank to the steam generating device.

[0074] Furthermore, in some embodiments, the liquid storage tank has a clean water storage area and a descaling agent storage area, and these two areas can be selectively connected.

[0075] In some embodiments, before the second solution stored in the liquid storage tank is input into the steam generating device, the method further includes the following steps:

[0076] The clean water storage area and the descaling agent storage area are controlled to be connected, so that the descaling agent in the descaling agent storage area can enter the clean water storage area and mix with the clean water to form a second solution.

[0077] The third solution may be clean water stored in the clean water storage area.

[0078] The pipeline connected between the liquid storage tank and the steam generating device can be directly connected to the clean water storage area of ​​the liquid storage tank.

[0079] Alternatively, in some embodiments, the steaming and baking device 10 further comprises a descaling agent storage device, the discharge port of the descaling agent storage device is located above the opening of the liquid storage tank, and the descaling agent stored in the descaling agent storage device can flow out from the discharge port and fall into the liquid storage tank.

[0080] In some embodiments, before the second solution stored in the liquid storage tank is input into the steam generating device, the method further includes the following steps:

[0081] The discharge port of the descaling agent storage device is opened so that the descaling agent stored in the descaling agent storage device can flow out from the discharge port and fall into the liquid storage tank.

[0082] In some other embodiments, before the second solution stored in the liquid storage tank is input into the steam generating device, the method further includes the following steps:

[0083] The liquid reservoir is controlled to be opened so as to add the second solution into the liquid reservoir.

[0084] Furthermore, if Figure 3 As shown, in some embodiments, the descaling method further comprises the following steps:

[0085] If the accumulated working time of the steaming and baking device 10 reaches the time threshold, the descaling instruction is triggered.

[0086] When the accumulated working time of the steaming and baking device 10 reaches the time threshold, the steaming and baking device 10 automatically enters the descaling working mode without the need for manual activation by the user.

[0087] Or, in other embodiments, Figure 4 As shown, the descaling method also includes the following steps:

[0088] If the accumulated working time of the steaming and baking device 10 reaches the time threshold, a descaling prompt message is generated, and the descaling prompt message is used to remind the user to trigger the descaling instruction.

[0089] When the descaling prompt information is formed, the user can choose to trigger the descaling instruction, and then the steaming and baking device 10 enters the descaling working mode.

[0090] In some cases, although the descaling prompt information is generated, if the steaming and baking device 10 is currently in a cooking state, the user can choose not to trigger the descaling instruction temporarily, and then manually trigger it after cooking is completed to ensure that the ongoing cooking process can be executed normally.

[0091] Furthermore, in some embodiments, the descaling method further comprises the following steps:

[0092] The time threshold is determined according to the water quality of the first solution.

[0093] The first solution is a solution used by the steam generator to form steam, and its water quality determines the difficulty of scaling in the steam generator to a certain extent. The time threshold is determined based on the water quality of the first solution, thereby making the start time of the descaling working mode more reasonable.

[0094] In some embodiments, the steaming and baking device 10 further includes a water quality detection sensor, and the water quality detection sensor is used to detect the water quality of the first solution input into the steam generating device.

[0095] In some embodiments, the descaling method further comprises the following steps:

[0096] Acquire water quality data detected by water quality detection sensors;

[0097] Determine duration thresholds based on water quality data.

[0098] Alternatively, the water quality of the first solution may be determined according to the water quality conditions in the area where the steam generating device is used.

[0099] For example, in some other embodiments, the descaling method further comprises the following steps:

[0100] Acquire the usage address data of the steam generating device, and determine the duration threshold according to the address data.

[0101] Furthermore, in some embodiments, Figure 5 As shown, the descaling method also includes:

[0102] Obtaining the duration of the steaming and baking device 10 executing different working modes;

[0103] A weighted calculation is performed on the durations during which the steaming and baking device 10 executes different working modes to determine the accumulated working duration of the steaming and baking device 10 .

[0104] The steam-bake device 10 may have steam-requiring working modes such as steam mode, steam-bake mode and fermentation mode. In these modes, the steam generating device needs to work to prepare steam, and the steam generating device will scale in the process. However, in different working modes, the probability of scaling in the steam generating device is different, and the scaling rate is different. Therefore, the duration of each working mode is weighted and calculated to determine the cumulative working time of the steam-bake device 10.

[0105] For example, in some embodiments, the cumulative working time of the steam generating device is positively correlated with the cumulative time of the steam-bake device 10 performing the steam function, the cumulative time of the steam-bake device 10 performing the steam-bake function, and the cumulative time of the steam-bake device 10 performing the steam-bake function, and the cumulative time of the steam-bake device 10 performing the fermentation function, and the cumulative time of the steam-bake device 10 performing the steam function has a greater impact on the cumulative working time of the steam generating device than the cumulative time of the steam-bake device 10 performing the steam-bake function. The cumulative time of the steam-bake device 10 performing the steam-bake function has a greater impact on the cumulative working time of the steam generating device than the cumulative time of the steam-bake device 10 performing the fermentation function.

[0106] Specifically in one embodiment, the cumulative working time T1 of the steam generating device, the cumulative time t1 of the steaming and baking device 10 performing the steaming function, the cumulative time t2 of the steaming and baking device 10 performing the steaming and baking function, and the cumulative time t3 of the steaming and baking device 10 performing the fermentation function satisfy the following relationship:

[0107] T1 = t1*1 + t2*0.5 + t3*0.2.

[0108] In other embodiments, the descaling method further includes: determining the cumulative working time of the steaming and baking device 10 according to the startup time of the steaming and baking device 10. For example, in some cases, the cumulative working time of the steaming and baking device 10 is the startup time of the steaming and baking device 10.

[0109] In some cases, the cumulative working time of the steam-bake device 10, the cumulative time of the steam-bake device 10 executing the steam function, the cumulative time of the steam-bake device 10 executing the steam-bake function, the cumulative time of the steam-bake device 10 executing the fermentation function and the power-on time of the steam-bake device 10 all meet the requirements of clearing the above time after the descaling working mode ends.

[0110] Furthermore, in some embodiments, a steam outlet 111 is provided on the side wall of the inner pot 11, and the steam generated by the steam generating device can enter the space enclosed by the inner pot 11 from the steam outlet 111; the steaming and baking device 10 also includes a hose, which can be optionally connected between the steam outlet 111 and the grease tray 12.

[0111] In some embodiments, the step of collecting the waste liquid generated by flushing the steam generating device into the grease pan 12 includes:

[0112] The control hose connects the steam outlet 111 and the grease pan 12 , and discharges the waste liquid generated by the flushing process from the steam outlet 111 into the grease pan 12 .

[0113] The waste liquid generated by the flushing process enters the grease pan 12 through the steam outlet 111 and the hose in sequence.

[0114] In some embodiments, the steam outlet 111 is provided with a multi-way valve, one water port of the multi-way valve is connected to the space enclosed by the inner tank 11, one water port of the multi-way valve is connected to a hose, and another water port of the multi-way valve is connected to the steam generating device. By controlling the conduction state between the water ports on the multi-way valve, the flow direction of the liquid from the steam generating device can be controlled.

[0115] The step of controlling the hose to connect the steam outlet 111 with the grease pan 12 includes: controlling the water port on the multi-way valve connected to the hose and the water port connected to the space surrounded by the inner tank 11 to be connected, so that the waste liquid generated by flushing the steam generating device is discharged from the hose to the grease pan 12.

[0116] Of course, in some embodiments, the step of collecting the waste liquid generated by flushing the steam generating device into the grease pan 12 includes:

[0117] The waste liquid generated by the steam generating device is controlled to flow toward the steam outlet 111 , so that the waste liquid generated by the flushing process is discharged from the steam outlet 111 into the inner pot 11 , and the waste liquid entering the inner pot 11 is discharged into the grease pan 12 .

[0118] In some embodiments, the steam outlet 111 on the inner tank 11 is connected to the steam generating device through a rear pipeline, and a switch valve or a third pumping device is provided on the pipeline.

[0119] The step of controlling the waste liquid generated by the steam generating device to flow to the steam outlet 111 includes:

[0120] Open the switch valve to connect the pipeline between the steam outlet 111 and the steam generating device, so that the waste liquid generated by the steam generating device flows along the pipeline to the steam outlet 111;

[0121] Alternatively, the third pumping device is started to pump the waste liquid generated by the flushing process to the steam outlet 111 .

[0122] Furthermore, in some embodiments, Figure 6As shown, the descaling working mode includes two cleaning processes and one rinsing process, and each cleaning process is executed for 9 minutes, and the rinsing process is executed for 6 minutes. The descaling working mode only includes one rinsing process, and the rinsing process is executed for 6 minutes, which can meet the cleaning requirements and only need to dump the grease tray 12 once, reducing the workload of the user.

[0123] In one embodiment, the execution time of the cleaning process refers to the time from when the second solution stored in the liquid storage tank begins to be input into the steam generating device to when all the waste liquid generated by the cleaning process is collected in the waste liquid storage device.

[0124] Similarly, the execution time of the flushing treatment process refers to the time from when the third solution stored in the liquid storage tank begins to be input into the steam generating device to when all the waste liquid generated by the flushing treatment is collected in the grease tray.

[0125] Specifically in some embodiments, the step of cleaning the steam generating device includes:

[0126] The heating element of the steam generating device is activated to heat the second solution.

[0127] The heating element can heat the second solution to make the scale on the steam generating device in the cleaning process more easily dissolve, thereby improving the cleaning effect.

[0128] Furthermore, in some embodiments, Figure 1 As shown, the bottom wall of the inner container 11 is also provided with a drying heating element 13 .

[0129] Accordingly, in some embodiments, Figure 6 As shown, the descaling method also includes the following steps:

[0130] The drying heating element 13 is started to dry out the moisture in the inner container 11 and the grease tray 12 .

[0131] After the user dumps the waste liquid in the grease pan 12, the execution step can be actively triggered, so that the drying and heating element 13 is started to dry the residual water of descaling.

[0132] Alternatively, the descaling method further comprises the following steps:

[0133] The drying heating element 13 is triggered to start according to the reloading data of the grease pan 12 to dry the moisture in the inner tank 11 and the grease pan 12 .

[0134] When it is detected that the grease pan 12 is reloaded, it is proved that the user has completed the dumping step, and the drying heating element 13 is started to dry the moisture in the inner tank 11 and the grease pan 12.

[0135] It should be understood that although Figure 2-Figure 6 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2-Figure 6 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.

[0136] Furthermore, in some other embodiments, the steaming and baking device 10 also includes a controller, the controller includes a memory and a processor, the memory stores a computer program, and the processor implements the steps of the above-mentioned descaling method for the steaming and baking device 10 when executing the computer program.
