Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0050] Understandably, the cooking performance of kitchen appliances, such as built-in ovens and steam ovens, is closely related to the humidity environment within the cooking zone (inner chamber). Different cooking processes have different humidity requirements. For example, baking requires lower humidity to prevent the food surface from forming a skin or cracking, while steaming and boiling require higher humidity to retain the moisture of the ingredients. Therefore, controlling the humidity within the cooking zone is crucial for ensuring the quality of the dishes.

[0051] Some cooking equipment does not have integrated humidity control components, so it cannot adjust the humidity inside the cooking area, making it difficult to meet the needs of different cooking processes.

[0052] In view of this, this application provides a cooking device, which includes an inner pot and a humidity control component disposed on the inner pot; the humidity control component includes an air duct structure, a detection module and an air intake module, the detection module includes a humidity detection element disposed on the air duct structure and a heat dissipation element for blowing airflow to the humidity detection element to dissipate heat; the air intake module is connected to the air duct structure and is communicatively connected to the detection module, and the air intake module is used to introduce external air into the inner pot through the air duct structure based on the detection result of the detection module.

[0053] The detection module can monitor the humidity inside the inner pot in real time, and the air intake module can perform humidity adjustment based on the monitoring results. The coordinated work of the detection module and the air intake module realizes the monitoring and adjustment of the humidity inside the inner pot, enabling the cooking equipment to dynamically maintain the humidity inside the inner pot within a preset range. This helps to meet the humidity requirements of different cooking processes and improves the cooking effect of the equipment.

[0054] The technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0055] Figure 1 is a schematic diagram of the cooking device provided in the embodiment of this application with the outer shell removed; Figure 2 is a schematic diagram of the connection structure between the detection module and the inner pot in the cooking device of Figure 1; Figure 3 is an exploded view of the detection module in the cooking device of Figure 1; Figure 4 is a schematic diagram of the air intake module in the cooking device of Figure 1.

[0056] Referring to Figures 1 to 4, this application provides a cooking device including a shell (not shown) and an inner pot 100. The inner pot 100 is disposed inside the shell, and a cooking area 102 is formed inside the inner pot 100. The cooking area 102 is used to hold food to be cooked.

[0057] It should be noted that the cooking equipment provided in this application includes, but is not limited to, household steam ovens, freestanding ovens, microwave ovens, commercial ovens, steam cabinets, etc.

[0058] The cooking appliance also includes a humidity control component disposed on the inner pot 100, which can be located between the inner pot 100 and the outer shell. The humidity control component includes an air duct structure 400, a detection module 200, and an air intake module 300.

[0059] For example, the detection module 200 serves as the sensing unit of the humidity control component, including a humidity detection element 220 disposed in the air duct structure 400 and a heat sink 230 for blowing airflow to the humidity detection element 220 to dissipate heat from the humidity detection element 220.

[0060] Specifically, the air duct structure 400 may include a first housing 410 and a second housing 420, which together form a channel for airflow. The heat sink 230 blows air into the channel, and the airflow flows to the humidity detection element 220 under the guidance of the channel. The first housing 410 and the second housing 420 may be fixedly connected by a snap-fit ​​structure, a screw structure, or a riveting structure to facilitate the disassembly and maintenance of the air duct structure 400.

[0061] For example, the air duct structure 400, as an airflow channel, can be made of stainless steel or high-temperature resistant engineering plastic to form a specific airflow channel, and its inner surface can be smoothed to reduce airflow resistance.

[0062] The humidity sensor 220 is used to directly or indirectly detect the humidity parameters of the air in the cooking area 102 of the inner pot 100. For example, the humidity sensor 220 can be a dew point humidity sensor, the core component of which is a metal mirror probe with high thermal conductivity. This probe is installed inside the air duct structure 400 and calculates the absolute humidity inside the inner pot 100 by measuring the temperature when condensation forms on the mirror.

[0063] Dew point humidity sensors can convert humidity measurements into temperature measurements, avoiding measurement drift and performance degradation caused by direct exposure of the sensor to high temperature and humidity environments, thus ensuring long-term reliability and accuracy. Of course, the humidity detection element 220 can also employ other types of humidity sensors, and this application embodiment does not impose any limitations on this.

[0064] The heat sink 230, such as a DC brushless fan or a centrifugal fan, can be fixedly connected to one end or side of the air duct structure 400. The forced airflow generated during operation can blow along the air duct structure 400 towards the humidity sensor 220, providing continuous air cooling for the humidity sensor 220. The rotation speed of the heat sink 230 is adjustable to provide suitable airflow according to different cooling requirements.

[0065] For example, as shown in Figure 3, the heat sink 230 is installed at one end of the air duct structure 400, and the other end of the air duct structure 400 or other parts of the air duct structure 400 may be provided with an air outlet to ensure smooth airflow inside the air duct structure 400.

[0066] The air intake module 300, as an execution unit, is communicatively connected to the detection module 200 and is used to introduce external air into the inner liner 100 based on the detection results of the detection module 200.

[0067] The signal connection between the detection module 200 and the intake module 300 can be implemented in several ways:

[0068] For example, the detection module 200 and the intake module 300 can establish a direct communication link. The detection module 200 and the intake module 300 can exchange data via wired or wireless communication protocols, such as UART, I2C, single bus, or Bluetooth.

[0069] Specifically, the detection module 200 may include a comparison unit for comparing the real-time humidity value with a preset humidity threshold and generating a switching command based on the comparison result. The detection module 200 sends the switching command to the intake module 300 to directly control the start and stop of the intake module 300.

[0070] Alternatively, the cooking device may also include a control module (not shown in the figure), with the air intake module 300 and the detection module 200 respectively communicatively connected to the control module. For example, the above-mentioned communication connection can be implemented through wired signal transmission or a wireless communication module.

[0071] For example, the control module, as the control core of the cooking equipment, can be a standalone controller or a functional unit integrated into the main control system of the cooking equipment. The control module is configured to receive signals from the detection module 200 and issue control commands to the air intake module 300 according to preset control logic.

[0072] Specifically, the control module can acquire real-time monitoring data from the detection module 200, and based on this data, when the humidity of the inner liner 100 exceeds a preset threshold, send a command to the air intake module 300 to start the air intake program.

[0073] In practical applications, multiple preset humidity thresholds can be set according to different cooking modes, for example:

[0074] In baking mode, a low cavity humidity needs to be maintained (e.g., relative humidity below 30%). At this time, the high humidity threshold for triggering air intake can be set to 35%.

[0075] In steam baking mode, a medium humidity environment (such as relative humidity of 50%-60%) may be required. In this case, the air intake module 300 can be set to be activated to intervene when the humidity exceeds 65%.

[0076] In high-temperature steaming mode, although a high-humidity environment is required, in order to prevent oversaturation and the resulting condensation dripping, which would affect the quality of the food, an upper limit threshold (such as 90%) can be set. When the humidity exceeds this limit, the air intake is activated to introduce some dry air for balance.

[0077] In practice, when the humidity detector 220 in the detection module 200 detects that the real-time humidity inside the cooking area 102 of the inner pot 100 exceeds the preset threshold set by the current cooking program, the control module generates and sends a control signal to the air intake module 300. After receiving this signal, the air intake module 300 starts working to introduce relatively dry external air into the cooking area 102.

[0078] Accordingly, when the humidity detection unit 220 detects that the real-time humidity data in the cooking area 102 does not exceed the preset humidity threshold of the current cooking program, the control module controls the air intake module 300 to stop working.

[0079] In another embodiment, the air intake module 300 may also be configured to automatically stop operating after introducing a predetermined flow rate of outside air into the cooking zone 102. Furthermore, the air intake module 300 may also be set to automatically stop operating after running at a constant flow rate for a preset duration.

[0080] It should be noted that the conditions for triggering the intake module 300 to stop operating are not limited to the above-mentioned conditions, and this application embodiment does not make specific limitations on them.

[0081] For example, the air intake module 300 can operate by turning on an air pump to pump in external air, or by opening an air intake port controlled by a solenoid valve, using the small pressure difference or convection that may exist inside and outside the inner liner 100 to introduce relatively dry ambient air into the high-temperature and high-humidity cavity of the inner liner 100.

[0082] The introduced dry external air mixes with the humid air inside the inner liner 100, thereby effectively diluting and reducing the overall humidity level inside the inner liner 100, bringing it back to the preset target range.

[0083] In summary, this embodiment of the application uses the detection module 200 to monitor the humidity in the cooking area 102 in real time, and the air intake module 300 to perform humidity adjustment actions in the cooking area 102 based on the monitoring results. The coordinated operation of the two realizes the monitoring and adjustment of humidity in the inner pot 100. This enables the cooking equipment to dynamically maintain the humidity in the inner pot 100 within a preset range, meeting the humidity requirements of different cooking processes and significantly improving the cooking effect.

[0084] In some embodiments, the air intake module 300 is connected to the air duct structure 400, thereby enabling external air to be introduced into the inner liner 100 through the air duct structure 400.

[0085] With this configuration, the air intake module 300 and the detection module 200 share the same air duct structure, reducing the number of independent pipes, simplifying the internal structure of the cooking equipment, and facilitating the miniaturization and weight reduction of the equipment.

[0086] For example, the air intake module 300 and the detection module 200 can be arranged sequentially along the air flow direction within the air duct structure 400. For instance, the air intake module 300 can be arranged between the air outlet of the air duct structure 400 and the air inlet of the inner liner 100 to deliver air from the air duct structure 400 to the inner side of the inner liner 100.

[0087] Specifically, a portion of the airflow passing through the humidity sensor 220 can be further delivered to the inner liner 100 by the air intake module 300. Specifically, the airflow generated by the heat sink 230, which has already passed through the humidity sensor 220 to complete its heat dissipation task, can continue to be introduced into the inner liner 100 through the air inlet. This portion of airflow, after passing through the humidity sensor 220, is relatively dry and preheated, making it suitable for diluting the high-humidity air inside the inner liner 100.

[0088] The above setup achieves a highly efficient "one airflow for two purposes" layout: after cooling the humidity detection element 220, the heat dissipation airflow can be further used to participate in humidity regulation, improving the integration and energy efficiency of the humidity control components.

[0089] For example, the air intake module 300 can be a controllable valve body, such as a solenoid valve, damper, or stepper motor-driven baffle, located at the air inlet of the inner liner 100. This valve body is communicatively connected to the control module. During non-humidification phases, or when the humidity inside the cavity is detected to be within the acceptable range, the control module can send a command to close the valve body, preventing airflow into the inner liner 100 and avoiding unnecessary interference. When the detection module 200 detects that the humidity exceeds the acceptable range and requires humidification, the control module then commands the valve body to open, allowing dry airflow to enter.

[0090] Furthermore, an air filter, such as a particulate air filter or an activated carbon filter, can be installed between the air intake module 300 and the air outlet of the air duct structure 400 to ensure that the air entering the inner liner 100 is clean and to avoid contamination of the cooking area.

[0091] In some embodiments, the air duct structure 400 may include a detection branch and an air intake branch (not shown). A humidity detection element 220 is disposed in the detection branch. The air intake module 300 is connected to the air intake branch to introduce external air into the inner liner 100 through the air intake branch.

[0092] It is understood that in this embodiment of the application, the air intake module 300 and the detection module 200 are arranged in parallel along the air flow direction within the air duct structure 400.

[0093] The detection branch is a dedicated airflow path for the humidity detection element 220. The humidity detection element 220 is located within this detection branch. Its main function is to ensure that a portion of the airflow generated by the heat sink 230 can be stably and centrally guided to the humidity detection element 220 for continuous and effective air cooling, thereby creating a stable and reliable local working environment for the humidity detection element 220 and ensuring its measurement accuracy and long service life.

[0094] The intake branch is a dedicated airflow path for delivering regulated air to the cooking zone 102. The intake module 300 is connected to this intake branch, and when it is necessary to reduce the humidity of the inner liner 100, the intake module 300 introduces outside air or treated air into the inner liner 100 through this branch.

[0095] For example, the air duct structure 400 may be equipped with a Y-shaped splitter at the air outlet end near the heat sink 230. After the airflow enters from the common inlet of the air duct structure 400, it can be divided into two independent channels: one channel forms a detection branch that leads directly to the humidity detection element 220; the other channel forms an intake branch that leads directly or through a connecting pipe to the intake module 300 and finally into the inner liner 100.

[0096] With this configuration, the air intake branch can also utilize the wind power generated by the heat sink 230 to convert a portion of the airflow into the aerodynamic force that delivers air into the inner liner 100. This avoids the problem of high internal air pressure in the inner liner 100 making it difficult for external air to enter, thus improving the integration and energy efficiency of the humidity control components and helping to simplify the structure and reduce costs.

[0097] Alternatively, the air duct structure 400 consists of two parallel but physically isolated air ducts, namely the detection branch and the intake branch, which are structurally completely independent. The two can share a common air inlet (connected to the heat sink 230), or they can each have independent air inlets (for example, the detection branch is connected to the heat sink 230, and the intake branch is connected to the dedicated fan of the intake module 300, etc.).

[0098] This structure achieves physical isolation of airflow, avoiding mutual interference. The control module can independently adjust the flow rate of the two branches by controlling the rotation speed of the heat sink 230 and the intake module 300 (or their dedicated fan).

[0099] Alternatively, the path from the air duct structure 400 to the humidity sensor 220 can be designated as the main air duct (i.e., the detection branch). A bypass port is created in the main air duct and connected to a pipe leading to the intake module 300, which constitutes the intake branch. A controllable valve body is installed at the inlet of the intake branch as the intake module 300. Under normal circumstances, this valve body is closed, and all airflow is used for heat dissipation of the detection branch. When humidity adjustment is required, the control module opens the valve body, and a portion of the airflow is diverted to the intake branch and then sent into the inner liner 100.

[0100] Of course, the detection branch and intake branch of the air duct structure 400 can also be formed in other ways, and this application embodiment does not impose any restrictions on this.

[0101] The dual-branch structure of the aforementioned duct structure 400 offers greater design flexibility. The dimensions and shape of the detection branch and the intake branch can be independently optimized according to their respective functional requirements. For example, the detection branch can be designed to be more compact to reduce airflow dead zones; the intake branch can be designed to be more robust to reduce flow resistance. This modular design allows the humidity control components to better adapt to different models and capacities of cooking appliances.

[0102] Referring to Figures 1 and 4, in some other embodiments, the inner liner 100 has an air inlet (not shown in the figures). The air intake module 300 includes an air intake pipe 310, the air intake end of which is connected to the external environment, and the air outlet end of which is connected to the air inlet.

[0103] The air intake pipe 310 of the air intake module 300 can be independently configured from the air duct structure 400 used by the detection module 200, ensuring the purity of the air source. The air intake module 300 can directly obtain fresh, dry air from outside the equipment or a specific area, ensuring the quality of the intake air. At the same time, the independent air intake module 300 also ensures that the air intake process is independent of the heat dissipation system, avoiding mutual interference between the two.

[0104] For example, the air inlet pipe 310 can be made of food-grade silicone tubing or stainless steel corrugated tubing, which has good temperature resistance and flexibility. Furthermore, the air outlet can be designed with a flared end to ensure that the incoming dry air is evenly distributed within the inner liner 100, thereby improving humidity control efficiency.

[0105] It should be noted that the air intake pipe 310 is located on the outside of the inner pot 100 and inside the outer shell of the cooking device. The outside air passing through the air intake pipe 310 will absorb heat between the outer shell of the cooking device and the inner pot 100 and become heated. Therefore, the temperature of the air entering the inner pot 100 will be around 50℃-60℃ to prevent low-temperature gases from the outside environment from directly entering the inner pot 100 and affecting the cooking effect.

[0106] In some embodiments, the intake pipe 310 may be connected to the air duct structure 400, and the intake pipe 310 may be reused to form an intake branch.

[0107] In some embodiments, the intake module 300 further includes a one-way valve 320 disposed on the intake pipe 310. The one-way valve 320 is open from the external environment to the interior of the inner liner 100.

[0108] The one-way valve 320 effectively prevents the backflow of high-temperature, high-humidity gas inside the inner liner 100. It prevents high-temperature, high-humidity, and oily gas from flowing back into the intake pipe 310 during non-intake periods, thus avoiding pipe contamination, bacterial growth, or scale buildup. Furthermore, the one-way valve 320 ensures that the inside of the intake pipe 310 remains dry, preparing for the next effective intake. In addition, the one-way valve 320 can also provide a degree of physical isolation in specific situations (such as a fire inside the inner liner 100).

[0109] For example, the check valve 320 can be connected to the inner liner 100 via the mounting base 321. The mounting base 321 can provide an installation position for the check valve 320, ensuring the positional stability of the check valve 320 during operation.

[0110] In some embodiments, the air intake module 300 further includes a fixing member 330, and the air outlet end of the air intake pipe 310 is connected to the inner liner 100 through the fixing member 330.

[0111] The fastener 330 is used to reliably connect the air outlet of the air inlet pipe 310 to the inner liner 100.

[0112] For example, the fastener 330 can be a quick-release flange joint, clamp, or threaded sealing joint to ensure a secure and airtight connection, and also facilitate daily maintenance and cleaning. In high-temperature environments, the fastener 330 can also be designed with thermal insulation to prevent heat conduction to the intake pipe 310.

[0113] As shown in Figure 2, in some embodiments, the humidity detection element 220 includes a heat-conducting part 221 and a temperature detection part 222.

[0114] The first part 2211 of the heat-conducting part 221 extends into the cooking area 102 of the inner pot 100 and directly contacts the cooking environment. The second part 2212 is located inside the air duct structure 400 and is in the airflow passage generated by the heat sink 230. The airflow generated by the heat sink 230 is directed to the second part 2212 so that the second part 2212 receives forced cooling from the heat sink 230.

[0115] This design is based on the measurement principle of a dew point humidity sensor: by controlling the cooling process of the heat-conducting part 221, when the surface temperature of the heat-conducting part 221 drops to the current dew point temperature of the air, water vapor begins to condense, and the temperature measured by the temperature detection part 222 at this time is the dew point temperature.

[0116] A temperature detection unit 222 is disposed on the heat-conducting part 221, and the temperature detection unit 222 is used to detect the temperature of the heat-conducting part 221.

[0117] For example, the temperature detection unit 222 can be disposed inside the heat conduction unit 221, for example, by using an embedded PT1000 temperature sensor, which can directly measure the core temperature of the heat conductor, with fast response, less influence from the external environment, and high measurement accuracy.

[0118] The temperature detection unit 222 can also be disposed on the surface of the heat-conducting part 221, for example, by using a surface-mount NTC thermistor, which is easy to install and has a low cost, but requires protective treatment on the surface to prevent contamination from affecting the measurement accuracy.

[0119] It should be noted that the first part 2211 and the second part 2212 can be an integral structure.

[0120] The specific working process of the humidity detection element 220 is as follows: the heat sink 230 continuously blows airflow to the second part 2212 of the heat conduction part 221 for forced cooling. Due to the excellent thermal conductivity of the heat conduction part 221 itself, this cooling effect is quickly conducted to the first part 2211 extending into the inner liner 100, thereby reducing its surface temperature. When the surface temperature of the first part 2211 is cooled to below the dew point temperature of the air inside the cavity, tiny dewdrops will condense on its surface. At this time, the temperature of the heat conduction part 221 (e.g., the first part 2211) is measured by the temperature detection element 222, and this temperature is the current dew point temperature of the air inside the inner liner 100. By using this dew point temperature and the ambient temperature inside the inner liner 100 (which can be obtained by other sensors, such as a temperature sensor installed inside the inner liner 100), the absolute humidity or relative humidity of the air inside the inner liner 100 can be calculated.

[0121] Specifically, the heat-conducting part 221 is a metal part.

[0122] Understandably, metallic materials such as copper, aluminum, or their alloys have excellent thermal conductivity, which helps to ensure that the cooling effect of the heat sink 230 on the second part 2212 is quickly transferred to the first part 2211 extending into the inner liner 100.

[0123] Metal components help ensure temperature uniformity throughout the heat-conducting section 221, making dew point temperature measurements more accurate and reliable. At the same time, metal materials possess good mechanical strength and corrosion resistance, enabling them to withstand the high-temperature and high-humidity environment inside cooking equipment.

[0124] In some embodiments, the inner liner 100 has an installation port 101, the heat-conducting part 221 is inserted into the installation port 101, and the outer side of the heat-conducting part 221 is fitted with a heat insulation member 223.

[0125] For example, the heat insulation element 223 may be made of a high-temperature resistant and low-thermal-conductivity material such as a ceramic fiber sleeve or a silicone sealing ring.

[0126] The heat insulation element 223 is filled between the outer wall of the heat-conducting part 221 and the side wall of the mounting port 101. Understandably, the inner wall of the cooking appliance 100 reaches a high temperature during operation. The heat insulation element 223, positioned between the outer wall of the heat-conducting part 221 and the side wall of the mounting port 101, not only provides heat insulation but also achieves a sealing effect. This design effectively prevents direct heat conduction from the inner wall of the 100 to the heat-conducting part 221 through the mounting port 101, eliminating interference from external heat sources and ensuring the accuracy of the dew point measurement process. Simultaneously, the elastic properties of the heat insulation element 223 compensate for the difference in thermal expansion and contraction between the metal heat-conducting part 221 and the mounting port 101.

[0127] As shown in Figure 3, in some embodiments, the detection module 200 further includes a temperature detection element 210, which is disposed within the air duct structure 400 and is used to detect the temperature inside the air duct structure 400.

[0128] Specifically, when the temperature detection element 210 detects that the air temperature in the heat dissipation duct exceeds the set threshold, the control module can determine that the heat dissipation conditions are insufficient and can take measures such as increasing the rotation speed of the heat dissipation element 230 or issuing an alarm to ensure the heat dissipation effect on the heat conduction part 221.

[0129] Meanwhile, by using the temperature detection element 210 to detect the temperature inside the air duct structure 400, it can also be used to correct and compensate the humidity detection algorithm of the humidity detection element 220.

[0130] The specific implementation method is as follows: The control module simultaneously collects the temperature of the heat-conducting part 221 (dew point temperature Td) and the air temperature (Ta) inside the air duct. Then, using these two temperature values, it accurately calculates the current relative humidity through a preset mathematical model (e.g., the Magnus formula based on the saturated water vapor pressure formula). When the ambient temperature rises, causing the air temperature (Ta) inside the air duct to rise, the preset mathematical model will automatically adjust the calculation parameters to ensure that the final output relative humidity value is still accurate, thereby eliminating the measurement error caused by ambient temperature fluctuations.

[0131] In some embodiments, the detection module 200 is disposed on the back or upper part of the inner liner 100. The air intake module 300 is disposed on the back or upper part of the inner liner 100.

[0132] It should be noted that the outer shell of the cooking equipment has a door on one side (usually the side facing the user), and the inner pot 100 has an inlet and outlet communicating with the cooking area 102 on the side facing the door. The side of the inner pot 100 away from the inlet and outlet is the back of the inner pot 100. For example, as shown in Figure 1, both the detection module 200 and the air intake module 300 are located on the back of the inner pot 100.

[0133] Understandably, the heat sources of the cooking equipment's inner liner 100 (such as heating elements at the bottom and sides) are mainly distributed in the lower and side sections. Placing the detection module 200 and the air intake module 300 in the relatively cooler back or upper section can keep them away from the main heat sources, reducing the impact of radiant and convective heat and creating a more favorable environment for humidity detection and the introduction of low-temperature, dry air.

[0134] Furthermore, the back and top of the inner liner 100 are typically areas with low space utilization. Placing the detection module 200 and / or the air intake module 300 in these areas helps optimize the overall internal structure of the cooking appliance. Simultaneously, air intake from the top or back can take advantage of the natural upward movement of hot air, allowing for better mixing of dry air with the humid air inside the cavity, thus improving humidity control efficiency.
