[0047] Housing 101, first side A, humidity sensor 131, temperature sensor 132, Hall sensor 133.

[0048] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0050] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The main solution of this application embodiment is: a method for controlling the drying and sterilization of the water tank assembly of a steam oven is applied to the water tank assembly of a steam oven. The water tank assembly is located between the inner liner and the outer shell of the steam oven. The outer shell of the water tank assembly is provided with a sterilizing lamp and multiple sensors. The method for controlling the drying and sterilization of the water tank assembly of a steam oven includes: detecting the working status of the steam oven; and controlling the sterilizing lamp according to the working status to dry and sterilize the water tank assembly.

[0052] Because existing technologies mostly use high-temperature drying methods, there are problems such as high energy consumption and incomplete sterilization.

[0053] According to the GB / T 19258 standard for ultraviolet germicidal lamps, ultraviolet light (UV-C) with a wavelength of 253.7nm has been proven to effectively destroy the DNA / RNA structure of microorganisms. Existing ultraviolet sterilizers (such as air sterilizers QB / T 5218 and water sterilizers) mostly adopt a combination of lamp tubes and filtration systems, but there are no known applications of them in the water tank components of steam ovens.

[0054] This application provides a solution that integrates a UV lamp assembly at the rear of the water tank to achieve waterproofing and moisture protection. By acquiring the working status of the steam oven, the sterilization lamp is controlled in conjunction with the working status of the steam oven. When the steam oven is not in operation, the sterilization lamp is automatically activated, and the ultraviolet photolysis accelerates the evaporation of water molecules, achieving the dual effects of sterilization and drying.

[0055] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device capable of performing the above functions, such as a controller for a steam oven. The following description uses a steam oven controller as an example to illustrate this embodiment and the subsequent embodiments.

[0056] Based on this, this application provides a method for controlling the drying and sterilization of the water tank assembly of a steam oven, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the drying and sterilization control method for the water tank assembly of the steam oven in this application.

[0057] In this embodiment, the drying and sterilization control method for the water box assembly of the steam oven is applied to the water box assembly 10 of the steam oven. The water box assembly 10 is located between the inner liner 11 and the outer shell (not shown in the figure) of the steam oven. The outer shell of the water box assembly is provided with a sterilization lamp 12 and multiple sensors 13.

[0058] like Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a steam oven. The steam oven consists of a shell, an inner liner 11, and a water tank assembly 10. It also includes other functional components, which will not be described in detail in this embodiment. Since the water tank assembly 10 is used to provide steam to help keep the food moist and improve the cooking effect, the water tank assembly 10 is in a humid environment for a long time, which can easily breed bacteria and produce odors. Therefore, in this embodiment, a sterilization lamp 12 and multiple sensors 13 are provided on the water tank assembly 10. The sterilization lamp is used to achieve the drying and sterilization of the water tank assembly 10.

[0059] The method for controlling the drying and sterilization of the water tank assembly of the steam oven includes steps S10 to S20:

[0060] Step S10: Detect the working status of the steam oven.

[0061] It should be noted that the sterilization lamp is linked to the working cycle of the steam oven, so the working status of the steam oven can be detected in real time to determine whether to turn the sterilization lamp on or off.

[0062] The operating status of a steam oven can include whether it is starting or stopping.

[0063] In one feasible implementation, step S10 may include steps A11 to A13:

[0064] Step S20: Control the germicidal lamp according to the working state to dry and sterilize the water box assembly.

[0065] It should be understood that the sterilizing lamp can be an ultraviolet sterilizing lamp, and the ultraviolet sterilizing lamp can be controlled according to the working status of the steam oven. For example, when the steam oven is in the working state of being stopped, the ultraviolet sterilizing lamp can be turned on to dry and sterilize the water box assembly 10.

[0066] This embodiment provides a method for controlling the drying and sterilization of the water tank assembly in a steam oven. The method is applied to the water tank assembly 10 of the steam oven, which is located between the inner liner 11 and the outer shell of the steam oven. The outer shell of the water tank assembly is equipped with a sterilizing lamp 12 and multiple sensors 13. The method includes: detecting the operating status of the steam oven; controlling the sterilizing lamp 12 according to the operating status to dry and sterilize the water tank assembly 10. Ultraviolet photolysis accelerates water molecule evaporation, achieving both sterilization and drying effects, thus reducing the cost of drying and sterilization.

[0067] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 Step S20 includes step S201:

[0068] Step S201: When the working state is stopped, control the germicidal lamp to turn on and dry and sterilize the water box assembly.

[0069] It should be noted that if the steam oven is in a stopped state, the sterilization lamp can still be turned on to dry and sterilize the water tank components.

[0070] In practice, the sterilization lamp uses pulsed irradiation control, which is linked to the working cycle of the steam oven. It is automatically activated during non-cooking stages to dry and sterilize the water tank components.

[0071] It should be noted that the germicidal lamp can be installed on the top of the water tank assembly's outer shell, so that when it is working, it can more comprehensively and effectively kill bacteria, mold and other microorganisms that may grow in the water tank, and perform large-scale drying treatment on the water tank assembly, expanding the drying and sterilization range of the water tank assembly.

[0072] like Figure 4 As shown, Figure 4This is a schematic diagram of the arrangement of the water tank assembly and the sterilizing lamp. The outer shell 101 of the water tank assembly 10 has a first side A, which is disposed away from the door of the steam oven. The sterilizing lamp 12 is installed on the top of the first side A.

[0073] By installing the germicidal lamp 12 on top of the water tank assembly 10, the direct contact between the inner wall of the water tank assembly 10 and water vapor can be reduced, avoiding the long-term contact between water vapor and the germicidal lamp 12 from affecting its effect. Furthermore, the top position makes it convenient for users to clean and maintain the germicidal lamp 12 and the water tank assembly 10, reducing the difficulty of maintenance during use. It also does not occupy the lower space of the water tank assembly 10, which helps to better utilize the capacity of the water tank assembly 10 and ensures the maximization of the internal space of the water tank assembly 10.

[0074] In one feasible implementation, to improve the intelligent control effect of the germicidal lamp 12, the working time of the germicidal lamp can also be set. Therefore, after step S201, the following steps are also included:

[0075] The operating time of the germicidal lamp is obtained; when the operating time of the germicidal lamp reaches the set operating time, the germicidal lamp is controlled to turn off.

[0076] It should be noted that the working time of the germicidal lamp is calculated from the start of the lamp's operation until the target working time. For example, if the germicidal lamp starts working at 10:00 and the current time is 10:10, then the working time of the germicidal lamp is 10 minutes.

[0077] To avoid high energy consumption due to continuous operation of the germicidal lamp, the germicidal lamp can be set to work in a cycle. For example, a threshold for the operating time can be set. When the operating time of the germicidal lamp reaches this threshold, the germicidal lamp will be controlled to turn off and stop working. For example, the operating time can be set to 15 minutes. After the operating time of the germicidal lamp reaches 15 minutes, it will turn off automatically and wait for the next time the steam oven is turned on to work, continuously performing the drying and sterilization cycle.

[0078] In this embodiment, when the working state is stopped, the sterilizing lamp is turned on to dry and sterilize the water tank assembly. By linking the sterilizing lamp with the working cycle of the steam oven, the water tank assembly is dried and sterilized in a timely manner to prevent bacterial growth.

[0079] Based on the first embodiment of this application, in the third embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 5 After step S20, the method for controlling the drying and sterilization of the water tank assembly of the steam oven further includes steps S21 to S22:

[0080] In this embodiment, the sensor disposed on the water box assembly includes a humidity sensor.

[0081] Step S21: Detect the humidity of the water box assembly using the humidity sensor.

[0082] It should be noted that, as Figure 6 As shown, Figure 6 The schematic diagram shows the structure of the sensor setup. The multiple sensors 13 include a humidity sensor 131, which is located at the bottom of the housing 101. The humidity sensor 131 detects the humidity of the water box assembly 10, thereby obtaining the real-time humidity of the water box assembly. By setting the humidity sensor 131 at the bottom, the humidity of the water box assembly can be detected more accurately.

[0083] Step S22: When the humidity of the water box assembly is greater than the preset humidity threshold, control the sterilization lamp to turn on and dry and sterilize the water box assembly.

[0084] In practical implementation, the preset humidity threshold can be set according to the requirements. The preset humidity threshold represents the humidity level inside the water box component. For example, the preset humidity threshold can be set to 30%RH, 40%RH, etc. For example, when the humidity of the water box component is greater than the preset humidity threshold of 30%RH, the sterilization lamp is activated to dry and sterilize the water box component.

[0085] Specifically, after the steam oven finishes working, the sterilization lamp can be turned off first, and then turned on when the humidity of the water tank component is greater than the preset humidity threshold. Alternatively, before the steam oven starts working again, the humidity of the water tank component can be checked to see if it is greater than the preset humidity threshold. If so, the sterilization lamp can be turned on.

[0086] In one feasible implementation, the multiple sensors also include a temperature sensor. After step S20, the method further includes: detecting the temperature of the water box assembly through the temperature sensor; and controlling the sterilization lamp to turn off when the temperature of the water box assembly is greater than a preset temperature threshold.

[0087] Continue as Figure 6 As shown, the plurality of sensors 13 include a temperature sensor 132, which is disposed at the bottom of the housing 101.

[0088] It should be noted that the temperature of the water tank assembly 10 is detected by the temperature sensor 132, thereby obtaining the real-time temperature of the water tank assembly. The temperature sensor set at the bottom can detect the temperature of the water tank assembly more accurately.

[0089] In practice, the preset temperature threshold can be set according to requirements. The preset temperature threshold represents the temperature change inside the water box component. For example, if the preset temperature threshold is set to 50℃, the sterilization lamp will be turned off when the temperature of the water box component is greater than the preset temperature threshold of 50℃, thereby completing the drying and sterilization of the water box component.

[0090] In this embodiment, the humidity sensor detects the humidity of the water tank assembly. When the humidity of the water tank assembly exceeds a preset humidity threshold, the sterilizing lamp is activated to dry and sterilize the water tank assembly. By monitoring the humidity inside the water tank in real time with the humidity sensor, the sterilizing lamp is automatically activated when the humidity is too high. By controlling the activation of the sterilizing lamp, the growth of bacteria and mold in high humidity conditions can be effectively reduced, maintaining a hygienic environment inside the water tank.

[0091] Based on the first embodiment of this application, in the fourth embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 7 After step S20, the method for controlling the drying and sterilization of the water tank assembly of the steam oven further includes steps S21' to S22':

[0092] In this embodiment, the plurality of sensors include Hall sensors.

[0093] Step S21': During the operation of the sterilization lamp, the door status of the steam oven is detected by the Hall sensor.

[0094] It should be noted that, as Figure 8 As shown, Figure 8 The diagram shows the structure of the Hall sensor setup. The multiple sensors 13 include a Hall sensor 133, which is positioned close to the door of the steam oven. The Hall sensor 133 detects the state of the steam oven door, thereby determining the door angle.

[0095] In practice, to prevent the user from suddenly opening the oven during the sterilization lamp's operation and causing a potential hazard, a Hall sensor located near the oven door can be used to detect the oven door's status during the sterilization lamp's operation.

[0096] It should be noted that the status of the oven door can include whether the oven door is open, the opening angle of the oven door, or the oven door is not open.

[0097] Step S22': Control the germicidal lamp according to the state of the door.

[0098] In practice, the sterilization lamp can be controlled by detecting the door status of the steam oven. For example, when the door is closed, the sterilization lamp can continue to dry and sterilize the water tank assembly until the sterilization time reaches the set running time, at which point the sterilization lamp will automatically turn off.

[0099] In one feasible implementation, step S22' may include: obtaining the door opening angle based on the door state; and controlling the germicidal lamp to power off and turn off when the door opening angle is greater than a preset angle threshold.

[0100] It should be noted that the opening angle of the oven door can be determined based on the door status. The preset angle threshold can be set to 5°. When the door opening angle is greater than 5°, it indicates that the user intends to open the oven. At this time, the sterilization lamp needs to be forcibly turned off to prevent the ultraviolet lamp from irradiating the user. The intelligent control effect of the sterilization lamp is improved by linking the Hall sensor with the door control switch.

[0101] It is understandable that an intelligent sensing system integrating multiple sensors can be implemented through an STM32 main control chip, thereby enabling multi-angle control of the germicidal lamp.

[0102] In this embodiment, during the operation of the germicidal lamp, the Hall sensor detects the door status of the steam oven; the germicidal lamp is controlled based on the door status. By linking the Hall sensor with the door control switch, the intelligent control effect of the germicidal lamp is improved.

[0103] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the embodiments of the water box assembly drying and sterilization control method of the steam oven of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0105] The steam oven provided in this application solves the technical problems of insufficient sterilization and high cost in the current treatment of the water tank of steam ovens. Compared with the prior art, the beneficial effects of the steam oven provided in this application are the same as those of the water tank assembly drying and sterilization control method of the steam oven provided in the above embodiments, and will not be repeated here.
