[0038] Technologies, circuits, and devices known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the above-mentioned technologies, circuits, and devices should be considered as part of the specification.

[0039] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. To facilitate the understanding of the embodiments of the present application, the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] In order to solve the technical problem in the prior art that each time the steam oven is cleaned, high-temperature steam needs to be heated and released, resulting in high energy consumption and a complicated cleaning process, the present application provides a steam oven cleaning method that can effectively utilize the actual temperature and humidity conditions inside the steam oven, and perform more targeted cleaning according to the degree of stains, thereby reducing energy consumption and simplifying the cleaning process.

[0042] Figure 1 A flow chart of a method for cleaning a steam oven provided in an embodiment of the present application. The method can be applied to a steam oven, and can usually be executed by a controller in the steam oven. In addition, the execution subject of the method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute the method, or a plurality of electronic devices can cooperate with each other to execute the method. When the above-mentioned execution subject is software, the method can be implemented as a plurality of software or software modules, or as a single software or software module. No specific limitation is made here.

[0043] like Figure 1 As shown, the method specifically includes:

[0044] Step 101, in response to triggering a cleaning operation on the steam oven, obtaining stain sensing information from a stain sensing device disposed at a target position.

[0045] In some embodiments, the cleaning operation can be triggered automatically or manually by the user. For example, the cleaning operation can be automatically triggered when the cooking operation of the steam oven is finished and the food in the steam oven is determined to be taken out (for example, by taking an image of the interior of the steam oven and identifying the image to determine whether the food has been taken out; or by sensing the weight of the food in the steam oven to determine whether the food has been taken out).

[0046] The target position is a position corresponding to the area in the steam oven where stains are easily generated. The stain sensing device may include various types of devices, for example, a sensor for sensing chemical substances (such as a sensor for detecting properties such as pH and salinity), a camera for taking stain images, etc.

[0047] Step 102: Determine the degree of stain corresponding to the spray direction of the spray device in the steam oven based on the stain sensing information.

[0048] In some embodiments, the position pointed by the spray direction of the spray device is the position where stains are likely to be generated. The degree of stain at the position can be determined by using the stain sensing information. The degree of stain is a numerical value indicating the amount of stain at the position, and a larger numerical value indicates a larger amount of stain. For example, a chemical substance detection sensor can be provided at the position pointed by the spray direction of the spray device, and the sensed stain sensing information can be analyzed to obtain the amount of stain, and the degree of stain is indicated by the amount of stain.

[0049] Step 103 : If the dirt level reaches a preset dirt level threshold, determine the internal temperature and internal humidity of the steam oven.

[0050] In some embodiments, the degree of dirt can be set in advance according to actual needs. If the preset dirt level threshold is reached, it means that the dirt level is high and cleaning may be required. At this time, it is necessary to further determine the internal temperature and internal humidity of the steam oven to determine whether the cleaning conditions are met.

[0051] Step 104 , if the internal temperature is greater than or equal to the preset temperature threshold, and the internal humidity is greater than or equal to the preset humidity threshold, control the spray device to spray water to clean the object located in the spraying direction.

[0052] In some embodiments, when the internal temperature is greater than or equal to a preset temperature threshold, and the internal humidity is greater than or equal to a preset humidity threshold, it means that the steam oven retains a lot of residual heat and a lot of steam after use, and at this time the spray device can be turned on to spray water outward. Under the effect of the residual heat and steam in the steam oven, the difficulty of cleaning stains can be greatly reduced, and the cleaning efficiency can be improved.

[0053] The objects in the above-mentioned spraying direction may include various objects, such as the inner wall of the steam oven, containers placed in the steam oven, etc.

[0054] The steam oven cleaning method provided in the embodiment of the present application obtains stain sensing information from a stain sensing device disposed at a target position when a cleaning operation on the steam oven is triggered, determines the degree of stain corresponding to the spray direction of the spray device in the steam oven based on the stain sensing information, and controls the spray device to spray water if the stain degree reaches a preset stain degree threshold, and the internal temperature and internal humidity of the steam oven meet the temperature and humidity conditions, so as to clean the object located in the spray direction. The embodiment of the present application implements a more targeted cleaning strategy according to the actual environmental conditions in the steam oven, effectively utilizes the temperature and humidity in the steam oven, and cleans according to different degrees of stain conditions, without having to heat up the steam oven and release steam every time cleaning, thereby helping to reduce energy consumption, simplify the cleaning process, and improve cleaning efficiency.

[0055] In some optional implementations, such as Figure 2 As shown, before step 102, the method further includes:

[0056] Step 105, determining the current cleaning mode of the steam oven.

[0057] The cleaning mode is used to limit the attributes such as the object to be cleaned in the steam oven, the cleaning time, and the cleaning intensity. For example, the cleaning mode may include a self-cleaning mode and a container cleaning mode. The self-cleaning mode is used to clean the steam oven itself, and the container cleaning mode is used to clean the containers placed in the steam oven.

[0058] Step 106: If the current cleaning mode is the self-cleaning mode, adjust the spraying direction of the spray device toward the inner wall of the steam oven.

[0059] The self-cleaning mode is a mode for cleaning the internal space of the steam oven itself. At this time, the spray direction of the spray device can be adjusted to the inner wall direction of the steam oven. Optionally, a motor can be set on the spray head of the spray device, and the controller sends a driving signal to the motor to drive the spray head to rotate to the inner wall direction. In addition, the spray device can include multiple spray heads, and the spray direction of each spray head is fixed. If the current cleaning mode is the self-cleaning mode, the spray head corresponding to the inner wall direction is controlled to spray water; if the current cleaning mode is the container cleaning mode, the spray head corresponding to the direction in which the container is placed is controlled to spray water.

[0060] Step 107 , if the current cleaning mode is the container cleaning mode, adjust the spray direction of the spray device to the direction in which the container is placed in the steam oven.

[0061] The utensil cleaning mode is a mode for cleaning food utensils placed in the steam oven. In this mode, the steam oven can be used as a dishwasher.

[0062] This embodiment sets a self-cleaning mode and a container cleaning mode, so that the steam oven can flexibly adjust the cleaning object according to the usage scenario, thereby expanding the function of the steam oven and improving the convenience of cleaning operations of the steam oven.

[0063] In some optional implementations, after the above step 107, the method further includes:

[0064] In response to the completion of spraying in the direction of the container, the cleaning mode is switched to the self-cleaning mode.

[0065] After switching to the self-cleaning mode, the spraying direction of the spray device can be further adjusted to the inner wall direction of the steam oven, and then the subsequent steps of the method can be continued to complete the cleaning of the inner wall of the steam oven.

[0066] This embodiment automatically switches to the self-cleaning mode after the container cleaning mode is executed, and continues to clean the inner wall of the steam oven in the self-cleaning mode, thereby further improving the automation level of the steam oven cleaning and improving the cleaning effect of the steam oven.

[0067] In some optional implementations, such as Figure 3 As shown, after step 103, the method further includes:

[0068] Step 108: If the internal temperature is lower than the preset temperature threshold, the heating device in the steam oven is controlled to operate so that the internal temperature reaches the preset temperature threshold.

[0069] Step 109: If the internal humidity is less than the preset humidity threshold, control the steam generating device in the steam oven to operate so that the internal humidity reaches the preset humidity threshold.

[0070] Among them, the heating device may include components such as a heating tube and a heating fan inside the steam oven. When the internal temperature is low, the steam oven can be heated up for easier cleaning.

[0071] The steam generating device can spray high-temperature steam under the control of the controller, and the high-temperature steam can soften the stains and facilitate cleaning.

[0072] This embodiment heats up the interior of the steam oven and releases steam when the internal temperature and humidity of the steam oven are low, so that the environment inside the steam oven can reach conditions that are easy to clean, thereby improving the cleaning effect.

[0073] In some optional implementations, such as Figure 4 As shown, the above step 104 includes:

[0074] Step 1041, determining a target cleaning intensity corresponding to the degree of stain from a preset cleaning intensity table.

[0075] The cleaning intensity table is used to indicate the corresponding relationship between the degree of dirt and the cleaning intensity. Different cleaning intensities can correspond to different water spraying speeds, different detergent spraying amounts, different temperatures, different humidity and other properties.

[0076] Step 1042, based on the target cleaning intensity, clean the objects in the target direction according to at least one of the following cleaning strategies: control the spray device to spray water according to the corresponding target spray speed; control the detergent spray device in the steam oven to spray detergent according to the corresponding spray amount; control the heating device to adjust the internal temperature to the temperature corresponding to the target cleaning intensity; control the steam generating device to adjust the internal humidity to the humidity corresponding to the target cleaning intensity.

[0077] The selection of the above three cleaning strategies can be set by the user in advance or before the steam oven leaves the factory. For example, the degree of soiling and the cleaning intensity can be graded, and different levels of soiling correspond to different levels of cleaning intensity. According to the level to which the currently determined soiling degree belongs, the corresponding water spraying speed, detergent spraying amount, temperature, and humidity can be determined from the cleaning intensity table.

[0078] This embodiment automatically adjusts the cleaning intensity according to the degree of stains by setting a correspondence between the degree of stains and the cleaning intensity, thereby helping to clean the stains more efficiently and improving the adaptability of the cleaning strategy to the actual conditions of the steam oven.

[0079] In some optional implementations, such as Figure 5 As shown, step 101 includes:

[0080] Step 1011, controlling the camera in the steam oven to photograph the objects inside the steam oven, and obtaining a stain image as stain sensing information.

[0081] The number of cameras may be one or more. When there are more than one camera, each camera may be used to shoot a different area to obtain a stain image corresponding to each area.

[0082] Step 102 includes:

[0083] Step 1021, identifying the stain image to obtain a recognition result indicating the degree of stain.

[0084] Usually, a pre-trained stain recognition model can be used to identify the stain image and determine the degree of stain. The above-mentioned stain recognition model can be trained in advance by a machine learning method. During training, a sample image can be input into an initial model (such as a deep convolutional neural network) to obtain a predicted degree of stain. Using a loss function (such as a cross entropy loss function), the predicted degree of stain is compared with the pre-calibrated true degree of stain to obtain a loss value representing the error. Then, the gradient descent method and the back propagation method are used to adjust the parameters of the initial model with minimizing the loss value as the optimization goal. The initial model is iteratively trained using multiple sets of training samples to eventually obtain a stain recognition model.

[0085] This embodiment realizes contactless identification of the degree of stains inside the steam oven, with higher identification accuracy and higher cleaning efficiency.

[0086] In some optional implementations, such as Figure 6 As shown, the method also includes:

[0087] Step 110, obtaining historical usage data recorded when the user uses the steam oven.

[0088] The historical usage data includes but is not limited to at least one of the following: ingredient category, usage frequency, and usage duration.

[0089] Specifically, the controller can record the user's use of the steam oven in real time. The food category refers to the food category put in the steam oven each time it is used, such as meat, vegetables, pasta, fried food, etc. The usage frequency can indicate how often the user uses the steam oven on average. The usage time indicates the time the user uses the steam oven each time. Different types of usage data have different degrees of stains on the steam oven, and different cleaning intensities can be set accordingly.

[0090] Step 111 : determining the cleaning frequency and default cleaning intensity of the steam oven based on the historical usage data.

[0091] The correspondence between the historical usage data and the cleaning frequency and the default cleaning intensity can be expressed by a pre-set correspondence table, a calculation formula, a machine learning model, etc. Different combinations of historical usage data will produce different degrees of stains, so the cleaning frequency and the default cleaning intensity need to be set specifically.

[0092] The cleaning frequency is the frequency of automatically triggering the cleaning operation. For example, the cleaning frequency may be to perform a cleaning operation once each time cooking is finished, or once every two cooking times, or once in each fixed cleaning cycle.

[0093] The default cleaning intensity is the minimum cleaning intensity used by default when performing a cleaning operation. The meaning of the cleaning intensity can be found in the above Figure 4 The corresponding embodiments are not described in detail here.

[0094] This embodiment makes statistics on the recorded historical usage data and updates the cleaning frequency and default cleaning intensity in real time, thereby achieving a better match between the cleaning method and the actual application scenario, which helps to further improve the cleaning effect.

The controller receives the stain sensing information, internal temperature and internal humidity collected by the stain sensing device, the temperature sensor and the humidity sensor, and executes the above-mentioned steam oven cleaning method based on the collected information, thereby realizing a more targeted execution of cleaning strategies according to the actual environmental conditions in the steam oven, effectively utilizing the temperature and humidity in the steam oven, and performing cleaning according to different degrees of stains. There is no need to heat up the steam oven and release steam every time cleaning, which helps to reduce energy consumption, simplify the cleaning process and improve cleaning efficiency.

[0113] In some optional implementations, such as Fig. 9 As shown, the steam oven further includes: a condensate guiding device 807 and a heat collecting device 808.

[0114] The condensed water guide device 807 is connected to the water tank 802 through a pipeline, and the condensed water guide device 807 is used to allow the water condensed from the steam inside the steam oven to flow into the water tank 802. The condensed water guide device 807 can guide the water generated by the condensation of steam during the use of the steam oven to flow into the water tank 802, thereby realizing the effective recovery of water resources.

[0115] Optionally, the number of water tanks 802 in this embodiment can be one or more. When there is one water tank, the water tank can be used to collect condensed water and can also be used to store clean water. When there are multiple water tanks, a separate condensed water collection tank and a separate clean water storage tank can be set.

[0116] The heat collection device 808 is connected to the spray device 803 and the water tank 802 through a pipeline. The heat collection device 808 is used to collect the heat of the steam in the steam oven and conduct the heat to the pipeline between the spray device 803 and the water tank 802 to increase the temperature of the water sprayed by the spray device 803.

[0117] The heat collection device 808 may include components such as heat storage materials and heat exchangers. The heat storage materials can store the heat generated during the use of the steam oven, and the heat exchanger can transfer the heat in the heat storage materials to part of the pipeline between the spray device 803 and the water tank 802, thereby heating the water used for cleaning.

[0118] This embodiment realizes effective recovery of water condensed from steam in the steam oven by arranging a condensed water diversion device and a heat collection device in the steam oven, thereby saving water resources, and effectively utilizing the heat generated in the steam oven to heat the water used for cleaning, thereby saving energy consumption.

[0119] In some optional implementations, such as Fig. 9 As shown, the steam oven further includes a heating device 809 and a steam generating device 810. The heating device 809 and the steam generating device 810 are both electrically connected to the controller 801. The controller 801 can send control signals to the heating device 809 and the steam generating device 810 respectively to control the start and stop of the heating device 809 and the steam generating device 810, and adjust the temperature of the heating device 809 and the steam spraying amount of the steam generating device 810.

[0120] The heating device 809 is used to heat the interior of the steam oven. The heating device 809 may include components such as a heating tube and a heating fan to heat various areas in the steam oven.

[0121] The steam generating device 810 is connected to the water tank 802 through a pipeline, and is used to extract water from the water tank 802 and convert the extracted water into steam. The steam generating device 810 can extract water from the water tank 802, heat the water, and convert it into high-temperature steam for ejection.

[0122] This embodiment arranges a heating device 809 and a steam generating device 810 in the steam oven, so that when the internal temperature of the steam oven is low and the internal humidity is low, the interior of the steam oven can be heated up and steam can be released, so that the environment in the steam oven can reach conditions that are easy to clean, thereby improving the cleaning effect.

[0123] Optionally, the steam oven may further include a detergent spraying device, which may be connected to the controller 801. The detergent spraying device may spray detergent outward according to the cleaning intensity under the control of the controller 801 to adapt to the degree of stains.

[0124] Optionally, the steam oven may further include a camera, which can take pictures of objects inside the steam oven to obtain a stain image as stain sensing information. The controller 801 recognizes the stain image to obtain a recognition result indicating the degree of stain.

[0125] Optionally, the controller 801 can also determine whether the current cleaning condition is met by identifying the image captured by the camera or obtaining the weight of the food from the weight sensing device included therein. If the steam oven is finished and there is no food, the cleaning operation can be automatically performed.

[0126] Optionally, the steam oven may further include a sewage discharge device, which may include components such as a filter, a sewage pipe, a sewage collection box, etc. The sewage generated by the cleaning operation may be discharged through the sewage discharge device.

[0127] Optionally, the steam oven may also be provided with a temperature protection function, that is, the controller 801 obtains the internal temperature of the steam oven in real time, and automatically shuts down when the temperature exceeds a threshold.

[0128] In addition, the above-mentioned controller can also have a communication function, that is, it can be connected to mobile phones, personal computers and other devices used by users through WiFi, Bluetooth, etc., receive information such as cleaning instructions issued by the user, and provide feedback to the user such as images after cleaning, data collected during cleaning, etc.
