[0040] The following description, with reference to the accompanying drawings, describes a method for monitoring steam leakage using a non-contact temperature sensor 30 for a cooking appliance according to a first aspect of the present invention.

[0041] Before introducing the steam leakage monitoring method of the non-contact temperature sensor 30 for cooking appliances according to embodiments of the present invention, it is necessary to first explain the application scenarios of the non-contact temperature sensor 30 steam leakage monitoring method for cooking appliances. The steam leakage monitoring method of the non-contact temperature sensor 30 for cooking appliances of the present invention is applicable to various types of cooking appliances that use the non-contact temperature sensor 30 to detect the temperature inside the cooking cavity, and can be applied to smart terminals such as smartphones, tablets, and computers. It can also be applied to servers connected to cooking appliances. The present invention does not impose special limitations on the application scenarios, as long as they can support and implement the steam leakage monitoring method of the non-contact temperature sensor 30 for cooking appliances.

[0042] Among them, the cooking utensils to which the non-contact temperature sensor 30 for monitoring steam leakage of cooking utensils proposed in this invention are applicable, combined with Figures 4 to 6 As shown, it includes a housing 1, a non-contact temperature sensor 30, and a heating assembly; the housing 1 is provided with a sealed and isolated cooking cavity and a sealed cavity 21; the non-contact temperature sensor 30 is disposed in the sealed cavity 21 and is adapted to form a detection field of view 31 in the direction of the cooking cavity to detect the temperature inside the cooking cavity; the heating assembly is adapted to heat the cooking cavity.

[0043] Combination Figure 1 and Figure 3 As shown, the method for monitoring steam leakage of a non-contact temperature sensor 30 for a cooking appliance according to a first aspect embodiment of the present invention includes: Step 100: During the heating process of the cooking appliance, the heating rate of the sealed cavity 21 where the non-contact temperature sensor 30 is located is obtained, wherein the non-contact temperature sensor 30 is used to detect the temperature inside the cooking cavity of the cooking appliance.

[0044] The phrase "during the heating process of the cooking appliance" refers to the user placing food in the cooking cavity and activating the cooking appliance to heat the food when they need to heat it. This can be achieved by installing a heating element in the cooking appliance to heat the cooking cavity and then heating the food. The heating element can be a direct heating method such as a heating rod or heating wire, or an indirect heating method such as a microwave generator or induction eddy current. It is understood that when using a microwave generator, a shielding layer is installed on the outside of the cooking cavity (or on the wall where the cooking cavity is located) to ensure user safety. The shielding layer can be made of materials with microwave shielding functions, such as metal layers or carbon fiber layers.

[0045] As the cooking appliance heats up, the temperature in the cooking cavity gradually diffuses into the sealed cavity 21, causing the ambient temperature of the sealed cavity 21 to rise. The rise in temperature corresponds to a heating rate.

[0046] Step 200: Based on the heating rate being greater than the set rate, it is determined that steam leakage has occurred in the sealed cavity 21 where the non-contact temperature sensor 30 is located.

[0047] The set rate is the rate of temperature rise of the sealed cavity 21 when the cooking appliance is in normal working condition (i.e., the sealed cavity 21 does not leak steam).

[0048] Understandably, during normal operation of the cooking appliance, because the sealing cavity 21 is sealed and isolated from the cooking cavity, the high-temperature and high-humidity steam in the cooking cavity will not enter the sealing cavity 21. At this time, the heating rate of the sealing cavity 21 relies on the heat transfer of the internal components of the cooking appliance, and its heating rate is less than or equal to the set rate. However, when the sealing cavity 21 leaks, the high-temperature and high-humidity steam enters the sealing cavity 21, causing the ambient temperature of the sealing cavity 21 to rise rapidly. At this time, the heating rate is greater than the set rate (e.g., Figure 8 Change to Figure 9 As shown, the increase in the heating rate ΔT indicates that steam leakage has occurred in the sealed cavity 21.

[0049] The heating rate can be determined based on a temperature sensor and a timer, i.e., the heating rate of the ambient temperature in the sealed cavity 21 can be obtained by measuring the temperature change per unit time.

[0050] In this embodiment, the temperature sensor can be the NTC (ambient temperature detection sensor) built into the non-contact temperature sensor 30, or a separate temperature sensor can be set.

[0051] It should be noted that in related technologies, cooking appliances typically use contact temperature sensors to detect food temperature. These sensors determine whether the food is boiling by identifying the temperature of the steam generated during heating. However, when cooking appliances are used to reheat food, the reheating temperature may not reach the point where enough steam is generated. This causes the contact temperature sensor to be unable to accurately detect the actual temperature of the food. Instead, it can only estimate the temperature based on heating time and power. For different types of food (with varying thermal conductivity) and different sizes, this indirect estimation is inaccurate, leading to overheating or underheating, thus affecting the user experience.

[0052] Based on this, this application proposes a technical solution for setting a non-contact temperature sensor 30. The non-contact temperature sensor 30 is disposed in the housing 1, and the temperature inside the cooking cavity (which can be the ambient temperature of the cooking cavity or the temperature of the food inside the cooking cavity) is detected through the detection field 31 of the non-contact temperature sensor 30. Correspondingly, a sealed cavity 21 needs to be set to isolate the non-contact temperature sensor 30 from the cooking cavity to prevent water vapor during the food heating process from coming into contact with the non-contact temperature sensor 30, thus preventing a reduction in its service life.

[0053] According to the steam leakage monitoring method of the non-contact temperature sensor 30 of the cooking appliance of the present invention, the method detects the heating rate of the ambient temperature value inside the sealed cavity 21 and compares it with the set rate when the sealed cavity 21 is not leaking under normal circumstances to determine whether the sealed cavity 21 is leaking steam. This method can intuitively understand the steam leakage situation of the sealed cavity 21, so as to avoid the non-contact temperature sensor 30 being exposed to high temperature and high humidity steam for a long time, which may lead to damage.

[0054] According to an embodiment of the present invention, step 100 includes: Step 110: If the ambient temperature of the sealed cavity 21 is determined to be higher than the set temperature value, then the heating rate is obtained.

[0055] In this embodiment, when the ambient temperature is lower than the set temperature, it indicates that there is no steam leakage in the sealed cavity 21, or even if steam leakage occurs, the temperature rise of the non-contact temperature sensor 30 caused by the steam leakage will not damage it. Therefore, there is no need to detect the heating rate, thereby reducing the detection power consumption of the cooking appliance and reducing the cost of use.

[0056] In this embodiment, the set temperature value can be the ambient temperature value of the non-contact temperature sensor 30 under certain experimental conditions (such as normal atmospheric pressure).

[0057] In one embodiment, the set temperature value is no greater than 85 degrees Celsius, for example, it can be 40 degrees Celsius. This adapts to steam leakage detection during the heating process of most foods, effectively reducing the power consumption of cooking appliances while preventing the non-contact temperature sensor from being exposed to high-temperature, high-humidity steam for extended periods due to excessively high set temperatures, which could cause damage.

[0058] Of course, adaptive adjustments are made based on different types of non-contact temperature sensors 30 (with different heat resistance).

[0059] According to one embodiment of the present invention, the following steps are included before step 200: Step 210: Obtain the cooking mode of the cooking appliance and the food information in the cooking appliance.

[0060] The cooking mode and food information can be determined based on user input. For example, users can set food information according to the type of food they need to cook. This information can also include details such as the quantity and moisture content of the food, which affect the ambient temperature inside the cooking cavity. Furthermore, users can select a cooking mode based on their needs. For instance, when the cooking mode includes a power level, it can have different levels such as Level 1 and Level 2. Different levels correspond to different target temperatures for the food. For example, Level 1 corresponds to a target temperature of 40 degrees Celsius for hot dishes, while Level 2 corresponds to a target temperature of 85 degrees Celsius for cooking rice. Users can choose different power levels based on their desired purpose (hot dishes or cooking rice, etc.). Different power levels correspond to different heating powers and heating times.

[0061] Of course, users may still encounter the problem of insufficient experience in actual use and being unable to select the appropriate setting. Therefore, the cooking mode can also be set to a food mode, that is, for different foods (such as rice, vegetables, meat dishes, etc.), corresponding rice cooking mode, vegetable hot dish mode, meat dish hot dish mode, etc. can be set. Users can select the corresponding food mode based on the actual food, which effectively improves the ease of use for users with less cooking experience who cannot determine the heating time and target temperature value for different foods.

[0062] The food information and cooking mode selection mentioned above can also be used together. When selecting a cooking mode (such as rice cooking mode), the user can input the amount of rice to be cooked and its consistency into the cooking appliance as food information.

[0063] Of course, food information and cooking modes can also be automatically identified by cooking appliances, such as cooking appliances equipped with sensors to detect the type, quantity, and moisture content of food and automatically select the appropriate cooking mode.

[0064] Step 220: Determine the set rate based on the cooking mode and food information.

[0065] As mentioned earlier, different types of food correspond to different cooking modes, and the food information of food under the same cooking mode may also be different. All of these will lead to different temperatures and humidity of the high-temperature and high-humidity steam in the cooking cavity during the actual heating process. Consequently, when the sealing cavity 21 leaks steam, the heating rate of the sealing cavity 21 will also be different. By combining the cooking mode and food information to accurately control the steam leakage of the sealing cavity 21 under different conditions, the accuracy of steam leakage judgment can be effectively improved.

[0066] Of course, the set rate can also be determined without using cooking mode and food information. Alternatively, it can be based on historical data and an empirical value to directly set the critical value of the set rate. In this case, regardless of the cooking mode or food information used, the criterion is that the heating rate exceeds the critical value.

[0067] In one embodiment, step 220 includes: Step 221: If the cooking mode is determined to be rice cooking mode, then the first set rate corresponding to the rice cooking mode is determined to be the set rate.

[0068] In this embodiment, the first set rate is 0.05 degrees Celsius / second. Of course, when the rice cooking mode is selected, food information (quantity of rice, water content, etc.) can also be input to adjust the first set rate and improve the accuracy of steam leakage detection.

[0069] Step 222: If the cooking mode is determined to be hot dish mode, then the second set rate corresponding to hot dish mode is determined to be the set rate.

[0070] In this embodiment, the second set rate can be 0.03 degrees Celsius / second, or it can be adjusted based on food information as above.

[0071] Of course, the cooking modes in this application are not limited to those listed above, and designers can set more cooking modes based on actual usage needs.

[0072] According to one embodiment of the present invention, after step 200, the following steps are included: Step 300: Control the cooking appliance to stop heating and send an error message.

[0073] The cooking appliance is controlled to stop heating, causing the steam temperature in the cooking cavity to gradually decrease. Correspondingly, the steam temperature in the sealed cavity 21 also decreases, effectively protecting the non-contact temperature sensor 30.

[0074] In this embodiment, error messages can be sent via at least one of light, voice prompts, or image displays.

[0075] In one embodiment, the error message is displayed as an indicator light. For example, different colored lights can be used to indicate whether the user's device meets or fails to meet the required standards. For instance, red indicates a steam leak requiring maintenance, while green indicates no steam leak and normal operation.

[0076] In one embodiment, the error message is a voice message. A separate error message is set for steam leakage, which helps users to accurately control the situation and improves the user experience.

[0077] In one embodiment, the error message is displayed as an image, prompting the user in the form of different text or icons. For example, in the case of a steam leak, an icon for "steam leak" is displayed.

[0078] The above error messages can be sent through error-reporting components on the cooking appliance (lights, displays, voice modules), or they can be sent to the user's mobile device in the form of electronic signals via mobile or wireless networks.

[0079] Combination Figure 2 As shown, the steam leakage monitoring device for the non-contact temperature sensor 30 of the cooking appliance according to the second aspect embodiment of the present invention includes: The acquisition module 610 is used to acquire the heating rate of the sealed cavity 21 where the non-contact temperature sensor 30 is located during the heating process of the cooking appliance, wherein the non-contact temperature sensor 30 is used to detect the temperature inside the cooking cavity of the cooking appliance. The determination module is used to determine that steam leakage has occurred in the sealed cavity 21 where the non-contact temperature sensor 30 is located, based on the fact that the heating rate is greater than the set rate.

[0080] The steam leakage monitoring device of the non-contact temperature sensor 30 of the cooking appliance according to the embodiment of the present invention has the same technical effect as the steam leakage monitoring method of the non-contact temperature sensor 30 of the cooking appliance according to the first aspect embodiment, and will not be described again here.

[0081] According to an embodiment of the present invention, the non-contact temperature sensor 30 of the cooking appliance includes a steam leakage monitoring device. The acquisition module 610 determines the heating rate if the ambient temperature of the sealed cavity 21 is higher than a set temperature value. The set temperature value can be no greater than 85 degrees Celsius.

[0082] The steam leakage monitoring device for the non-contact temperature sensor 30 of the cooking appliance according to an embodiment of the present invention further includes: a calculation module, used to acquire the cooking mode of the cooking appliance and food information in the cooking appliance, and to determine a set rate based on the cooking mode and food information. Specifically, if the cooking mode is determined to be a rice cooking mode, then a first set rate corresponding to the rice cooking mode is determined as the set rate; or, if the cooking mode is determined to be a hot dish mode, then a second set rate corresponding to the hot dish mode is determined as the set rate; the first set rate is greater than the second set rate.

[0083] The steam leakage monitoring device for the non-contact temperature sensor 30 of the cooking appliance according to an embodiment of the present invention further includes: an error reporting module, used to control the cooking appliance to stop heating and send an error message after determining that steam leakage has occurred in the sealed cavity 21 where the non-contact temperature sensor 30 is located. It should be noted that all content of the first aspect embodiment can be used to explain the steam leakage monitoring device for the non-contact temperature sensor 30 of the cooking appliance in the second aspect embodiment; therefore, some repeated content will not be described again.

[0084] Combination Figures 4 to 6 As shown, a cooking appliance according to a third aspect embodiment of the present invention includes: a housing 1, a non-contact temperature sensor 30, a heating assembly, and a controller; the housing 1 is provided with a sealed and isolated cooking cavity and a sealed cavity 21; the non-contact temperature sensor 30 is disposed in the sealed cavity 21 and is adapted to form a detection field of view 31 in the direction of the cooking cavity to detect the temperature inside the cooking cavity; the heating assembly is adapted to the cooking cavity; the controller is electrically connected to the non-contact temperature sensor 30 and the heating assembly, and is used to execute the steam leakage monitoring and control method of the non-contact temperature sensor 30 of the cooking appliance of the above embodiment.

[0085] In this embodiment, the non-contact temperature sensor 30 adopts a far-infrared temperature sensor, which can measure temperature without contacting food, avoiding damage or contamination to the food. It also has a fast response speed, which can complete the measurement of the temperature of the target object within a few milliseconds, effectively preventing the food from being overheated. Of course, radiation temperature measuring instruments, laser temperature measuring instruments, etc. can also be used.

[0086] According to one embodiment of the present invention, the housing 1 includes a cover 20 and a cooking body, the cover 20 and the cooking body enclosing each other to form a cooking cavity; the cover 20 is provided with a sealing cavity 21, and the cover 20 has a through hole 32 connecting the sealing cavity 21 and the cooking cavity, and an optical lens 50 is sealed and connected in the through hole 32, the optical lens 50 being adapted to detect the passage of the field of view 31.

[0087] In this embodiment, the housing 1 may include a cover 20 and a cooking body, which together form a cooking cavity. The non-contact temperature sensor 30 and the optical lens 50 may be disposed on the cover 20 and located above the cooking cavity. Alternatively, the non-contact temperature sensor 30 and the optical lens 50 may be disposed on the cooking body, such as at the bottom of the cooking cavity, suitable for detecting the temperature in the field of view 31.

[0088] In this embodiment, the optical lens 50 is a filter (silicon dioxide lens), which can effectively filter infrared light in a specific frequency band; of course, different types of optical lenses 50 can be set based on different types of non-contact temperature sensors 30.

[0089] The optical lens 50, which is sealed within the through hole 32, prevents leakage between the sealed cavity 21 and the cooking cavity through the through hole 32.

[0090] According to one embodiment of the present invention, the cover 20 includes an outer shell 22 and a sealing mounting base 23 detachably connected to the outer shell 22. The sealing mounting base 23 includes a sealing upper cover 231 and a sealing base 232. The sealing upper cover 231 and the sealing base 232 enclose a sealing cavity 21, and a sealing element 233 is provided at the connection between the sealing upper cover 231 and the sealing base 232. The sealing base 232 has a through hole 32. The outer shell 22 and the cooking body enclose a cooking cavity.
