Description

Technical Field

[0001] This invention relates to the field of electrical technology, and in particular to a control method for a cooking device and a cooking device. Background Technology

[0002] Steam cooking equipment such as steam ovens and electric steamers are kitchen appliances that use heating elements to convert water into high-temperature steam to cook food. During the use of an electric oven, a large amount of steam is generated, and the generated steam usually needs to be discharged to the outside to maintain the pressure balance inside the steamer and ensure cooking efficiency.

[0003] In the prior art, a steam discharge device is usually installed at the top of the inner tank to discharge steam. The steam discharge device has a steam discharge channel and a condenser installed inside the steam discharge channel. After the steam in the inner tank enters the steam discharge channel, it is condensed and cooled by the condenser and then discharged through the gap between the control device and the top of the door, so as to reduce the amount of steam discharged and lower the steam discharge temperature.

[0004] To improve the ease of use of steam cooking equipment, some models feature retractable door handles at the top of the door. When not in use, the handle is flush with the front of the door, preventing accidental bumps. When needed, the handle extends for opening and closing. However, because the handle is positioned between the control unit and the top of the door, it fills the gap originally used for steam venting. This prevents steam from venting smoothly from the front of the steam cooking equipment with retractable handles, hindering the proper discharge of steam from the inner tank and impacting the overall usability of the steam cooking equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a control method and cooking equipment for cooking equipment, so as to improve the user experience of cooking equipment while realizing steam emission during the cooking process.

[0046] A cooking device includes an inner pot with a steam vent. The device also includes a door assembly comprising a door and a handle mounted on the top of the door. The handle is switchable between an extended state (forwardly extended relative to the door) and a retracted state (retracted relative to the extended state). A door steam passage is provided inside the door, and an upper steam passage is provided above the door by the door assembly.

[0048] The control method for the cooking equipment provided in this embodiment can control the steam discharge path according to the cooking state during the cooking process, thereby selectively discharging steam into the interior of the door to improve the flexibility of steam discharge and enhance the user experience of the cooking equipment. Simultaneously, when the cooking equipment is in normal working condition, the steam in the inner pot is discharged sequentially through the steam outlet, the upper steam passage, and the door steam passage. This results in a longer discharge path for the steam, facilitating condensation, reducing the temperature and volume of the discharged steam, and preventing the door handle from protruding relative to the front of the door and causing bumps to the user, thus improving the reliability and safety of the cooking equipment. When the cooking equipment is in an abnormal working state, the door handle is extended to allow steam to quickly discharge through the space above the door, better meeting the steam discharge needs of various cooking states and further enhancing the user experience of the cooking equipment.

[0049] The cooking equipment provided in this embodiment controls the operation of the cooking equipment by adopting the control method described above, so that the steam emission of the cooking equipment can better meet the needs of various cooking states, improve the reliability and safety of the cooking equipment, and enhance the user experience of the cooking equipment.

[0083] Example 1

[0084] This embodiment provides a cooking device and a method for controlling the cooking device, so as to control the steam emission of the cooking device according to the cooking state and improve the user experience of the cooking device.

[0085] The cooking equipment includes a main body, a door assembly, a control device, and a steam supply device. The main body includes a casing and an inner pot installed inside the casing, the inner pot having a cooking cavity with a front opening. The door assembly is located on the front of the main body and its lower end is rotatably connected to the main body, allowing the door assembly to switch between a closed state (closing the cooking cavity opening) and an open state (opening the cooking cavity). The steam supply device supplies hot steam to the inner pot to cook the food inside. The control device is installed on the front of the main body and above the door assembly; the control device is used by the user to operate the cooking equipment and control its operation. The steam supply device is communicatively connected to the control device.

[0086] To facilitate user operation of the door assembly, in this embodiment, the door assembly includes a door and a door handle. The lower end of the door is rotatably connected to the machine body, and the door handle is located at the top of the door and can switch between an extended state relative to the door and a retracted state relative to the extended state. Therefore, when the door handle is not needed, it is in the retracted state, and the front side of the door handle does not protrude from the front side of the door, ensuring the flatness of the door assembly and reducing the probability of the door handle bumping into the user. When the door handle is in the extended state, it protrudes forward relative to the door, making it convenient for the user to grip and use the door handle to open and close the door.

[0087] Because cooking equipment requires a continuous flow of hot steam into the inner pot to maintain the temperature inside, and also needs to release the steam to prevent excessive pressure inside the pot, a steam vent is provided on the inner pot to facilitate steam release.

[0088] In this embodiment, a steam passage is provided inside the door, and an upper steam passage is provided above the door assembly. When the door handle is in the retracted state, the steam discharge port, the upper steam passage, and the door steam passage are connected in sequence so that the steam in the inner liner can be discharged into the upper steam passage. When the door handle is in the extended state, the steam discharge port is connected to the front space of the door assembly through the space above the door so that the steam discharged from the inner liner can be discharged to the outside of the door assembly through the space above the door.

[0089] like Figure 1 As shown, this embodiment also provides a control method for a cooking device, the control method including:

[0090] When the cooking equipment is in normal working condition, the control door handle is in the retracted state so that the gas in the inner pot can be discharged in sequence through the steam vent, the upper steam passage and the door steam passage.

[0091] When the cooking equipment is in an abnormal working state, the control door handle is extended so that the gas in the inner pot can be discharged to the outside of the door assembly through the steam vent and the space above the door in sequence.

[0092] The control method for the cooking equipment provided in this embodiment can control the steam discharge path according to the cooking state during the cooking process, thereby selectively discharging steam into the interior of the door to improve the flexibility of steam discharge and enhance the user experience of the cooking equipment. Simultaneously, when the cooking equipment is in normal working condition, the steam in the inner pot is discharged sequentially through the steam outlet, the upper steam passage, and the door steam passage. This results in a longer discharge path for the steam, facilitating condensation, reducing the temperature and volume of the discharged steam, and preventing the door handle from protruding relative to the front of the door and causing bumps to the user, thus improving the reliability and safety of the cooking equipment. When the cooking equipment is in an abnormal working state, the door handle is extended to allow steam to quickly discharge through the space above the door, better meeting the steam discharge needs of various cooking states and further enhancing the user experience of the cooking equipment.

[0093] The cooking equipment provided in this embodiment controls the operation of the cooking equipment by adopting the control method described above, so that the steam emission of the cooking equipment can better meet the needs of various cooking states, improve the reliability and safety of the cooking equipment, and enhance the user experience of the cooking equipment.

[0094] The passage between the steam exhaust port and the air inlet of the upper steam passage is defined as the machine body steam passage. In this embodiment, abnormal operating states include:

[0095] The temperature value of the door handle is equal to or greater than the first preset temperature value;

[0096] Alternatively, the exhaust humidity value at the steam passage of the machine body is lower than the first preset exhaust humidity value;

[0097] Alternatively, the humidity value inside the door in the door steam passage is equal to or higher than the first preset humidity value inside the door.

[0098] During the operation of cooking equipment, when the equipment is in normal working condition, the steam discharged from the inner pot enters the door steam channel through the upper steam channel. When the steam temperature is high or the steam discharge volume is large, the heat of the steam discharged into the upper steam channel will cause the door handle temperature to rise. If the door handle temperature is too high, it may cause burns when the user touches the door handle, thus affecting the user's safe use of the cooking equipment. Therefore, when the door handle temperature is equal to or greater than the first preset temperature value, it indicates that the door handle temperature is too high and there is a safety hazard of burns to the user. Therefore, it is necessary to keep the door handle in the extended state so that the door handle can extend forward relative to the door, thereby increasing the contact area between the door handle and the outside air, achieving rapid heat dissipation of the door handle, cooling the door handle, and preventing the door handle temperature from rising too high, thereby improving the safety of using the cooking equipment.

[0099] During the operation of cooking equipment, a significant amount of steam is required during steaming and boiling. In baking mode, the exhaust gas from the inner pot has a lower humidity level and contains more grease. If this exhaust gas is channeled into the inner steam channel, the grease in the gas will adhere to the inside of the door as it passes through the door steam channel, easily causing odors and mold growth inside the door. This increases the difficulty of cleaning the door assembly and negatively impacts the long-term user experience of the cooking equipment. Therefore, in this embodiment, when the exhaust humidity level at the steam channel is lower than a first preset exhaust humidity level, it can be determined that the steam content of the inner pot exhaust is low, posing a risk of high grease content. Therefore, the door handle needs to be switched to the extended position so that the exhaust gas from the inner pot can be discharged directly to the front space of the door assembly without passing through the door steam channel, reducing the probability of grease entering the door, improving the ease of cleaning the door, and enhancing the long-term user experience of the cooking equipment.

[0100] During the operation of the cooking equipment, if the humidity value inside the door steam channel is equal to or higher than the first preset humidity value, it indicates that the amount of steam discharged from the inner pot is large. A large amount of steam entering the door can easily cause problems such as increased door temperature and untimely steam discharge. It can also easily cause a large amount of water stains on the ground or inside the cabinet where the cooking equipment is installed, affecting the normal use of the cooking equipment. Therefore, in this embodiment, when the humidity value inside the door steam channel is equal to or higher than the first preset humidity value, the cooking equipment is judged to be in the first abnormal working state. It is necessary to control the door handle to be extended so that the steam can be discharged directly through the space above the door, reducing the resistance to steam discharge and improving the efficiency of steam discharge. This avoids the problem of high internal pressure in the inner pot caused by untimely steam discharge, thereby improving the reliability and safety of the cooking equipment.

[0101] For ease of description, the abnormal working state in which the handle temperature value of the door handle is equal to or greater than the first preset temperature value is called the first abnormal working state; the abnormal working state in which the exhaust humidity value at the steam passage of the machine body is lower than the first preset exhaust humidity value is called the second abnormal working state; and the abnormal working state in which the humidity inside the door steam passage is higher than or equal to the first preset humidity value is called the third abnormal working state.

[0102] In this embodiment, the cooking device has a steaming and baking function, that is, it can not only cook food in a steaming mode, but also steam or boil food in a non-steaming mode. In this embodiment, the abnormal working state includes a first abnormal working state, a second abnormal working state, and a third abnormal working state. When any abnormal working state occurs during the cooking process, the door handle is controlled to switch to the extended state.

[0103] In other embodiments, the cooking device may only have a steaming function, but not a baking function or other cooking methods without steaming. Abnormal working states may include a first abnormal working state and / or a third abnormal working state, but not a second abnormal working state.

[0104] Furthermore, to enhance the user's autonomy and flexibility in controlling the cooking equipment, in this embodiment, the abnormal working state also includes: receiving a user's instruction to extend the handle.

[0105] This means that users can control the operation of cooking equipment through control devices, voice input modules, or apps, thereby increasing user autonomy and improving the user experience. Users can issue a handle extension command to the cooking equipment based on their needs, such as adding food or seasonings to the cooking cavity, lowering the door handle temperature, or other needs requiring the door handle to extend. This controls the door handle to switch from a retracted to an extended state, better meeting the user's cooking preferences and enhancing the cooking experience.

[0106] For ease of description, the abnormal working state of the cooking equipment when it receives a user's instruction to extend the handle is referred to as the fourth abnormal working state.

[0107] In this embodiment, to further improve the automation of the cooking equipment, the control method further includes:

[0108] Determine the cooking mode when the cooking equipment starts running;

[0109] When the cooking mode is set to non-steam mode, the control door handle remains extended throughout the cooking process.

[0110] Before the cooking equipment is started, users typically select the cooking mode based on the food to be cooked, or the control device automatically selects the cooking mode by detecting the food. When the user selects a non-steam mode or the control device determines the cooking mode, it indicates that the amount of steam generated in the inner pot is minimal or nonexistent throughout the cooking process, and the exhaust gas from the inner pot will inevitably contain a high amount of grease. Therefore, when the cooking mode is non-steam, the control device keeps the door handle extended from the initial state to prevent grease from the exhaust gas from the inner pot from entering the inner pot. This eliminates the need to determine whether to extend the door handle based on the amount of steam exhaust in the steam channel, simplifying the operation and control of the cooking equipment, reducing the difficulty of control, and effectively preventing grease from entering the inside of the door.

[0111] It is worth noting that the steam-free mode includes the baking mode, frying mode, or other modes that do not require the use of steam to cook food.

[0112] Furthermore, the control method provided in this embodiment also includes:

[0113] When the cooking mode is set to steam mode, the control door handle is initially in the retracted state.

[0114] During the cooking process, the operating parameters of the cooking equipment are monitored in real time, including the handle temperature of the door handle, the exhaust humidity at the steam passage of the machine body, and / or the humidity inside the door in the steam passage of the door.

[0115] Determine whether the cooking equipment is in an abnormal working state based on the operating parameter values.

[0116] In this embodiment, if the cooking mode is a steaming mode, it means that at least some stage of the cooking process will generate a large amount of steam. Therefore, at the start of cooking, the door handle is controlled to be in a retracted state to reduce the probability of subsequent door handle switching. During the cooking process, the operating parameters of the cooking equipment are detected to determine whether the cooking equipment is in an abnormal working state. The abnormal working state can be automatically identified in a timely manner to ensure the normal, safe and reliable operation of the cooking equipment.

[0117] It is worth noting that the steaming mode includes, but is not limited to, pure steaming mode and steam-bake mode. In pure steaming mode, hot steam is used to cook the food throughout the entire cooking process. In steam-bake mode, the food is cooked through both steaming and baking stages.

[0118] It is worth noting that, in determining whether the cooking state is in an abnormal working state based on the operating parameter values, the abnormal working state is either the first abnormal working state, the second abnormal working state, or the third abnormal working state.

[0119] That is, in this embodiment, the control method specifically includes the following steps:

[0120] Step S101: Start the cooking equipment;

[0121] Step S102: Determine whether it is in steam mode. If not, proceed to step S103. If yes, proceed to step S104.

[0122] Step S103: Control the door handle to be in the extended state;

[0123] Step S104: Control the door handle to be in the retracted state;

[0124] Step S105: Detect the operating parameter values;

[0125] Step S106: Based on the operating parameter values, determine whether it is an abnormal working state. If yes, proceed to step S107; otherwise, return to step S105.

[0126] Step S107: Switch the door handle to the extended position.

[0127] Example 2

[0128] This embodiment provides a cooking device and a control method for the cooking device. The control method for the cooking device provided in this embodiment is a further improvement on the control method provided in Embodiment 1. This embodiment will not repeat the same content as in Embodiment 1.

[0129] In this embodiment, the control method includes:

[0130] When the cooking equipment is started, determine the cooking mode;

[0131] During the cooking process, the operating parameters of the cooking equipment are monitored in real time, including the handle temperature of the door handle, the exhaust humidity at the steam passage of the machine body, and the humidity inside the steam passage of the door. The cooking status is determined based on the operating parameter values ​​to determine whether the cooking status is abnormal.

[0132] In this embodiment, during the cooking process, the handle temperature, exhaust humidity, and door humidity are simultaneously detected to detect and identify various possible abnormal working conditions, thereby ensuring the reliability and safety of the cooking equipment.

[0133] In this embodiment, the control method further includes: during the cooking process, detecting the gas humidity value at the outlet of the steam channel of the machine body, and using the detected value as the exhaust humidity value.

[0134] Therefore, the steam discharged from the inner liner will partially condense and cool down after passing through the steam passage of the machine body. This means that the humidity level within the steam passage gradually decreases in the direction away from the steam outlet, and the steam temperature also gradually decreases in the same direction. Detecting the humidity level of the gas at the outlet of the steam passage improves the ease of detection and allows for effective determination of the steam content discharged to the door assembly, thus determining whether the gas needs to pass through the door steam passage and improving the reliability of the detection.

[0135] In other embodiments, the gas humidity value at other locations within the steam passage of the machine body can also be detected, and the detected value can be used as the exhaust humidity value. However, it is understood that since the gas humidity value at different locations within the steam passage of the machine body is different at the same time, the first preset humidity value should be specifically set according to the detection location of the gas humidity value and the structure within the steam passage of the machine body.

[0136] In this embodiment, a humidity detection device is installed in the steam channel of the machine body to detect the humidity value of the gas. The humidity detection device is communicatively connected to the control device. The specific installation structure and detection principle of the humidity detection device can be set based on the existing structure, and this embodiment does not limit it in this way.

[0137] As steam flows from the inlet to the outlet of the steam passage, it is gradually condensed and cooled. Generally, the amount of steam at the inlet of the steam passage is greater than that at the outlet. The difference in steam volume varies depending on the condensation effect of the steam passage. For example, if the amount of steam at the inlet is large, and no other condensation structure is installed inside the steam passage or no heat dissipation structure is installed outside the steam passage, the difference between the steam volume at the inlet and outlet is the first difference. If a heat dissipation structure is installed outside the steam passage, the difference between the steam volume at the inlet and outlet is the second difference. Since the heat dissipation structure enhances the condensation effect of the steam inside the steam passage, the second difference is greater than the first difference.

[0138] Therefore, to increase the control precision of the cooking equipment, in this embodiment, the control method further includes:

[0139] During the cooking process, the humidity of the gas at the steam outlet of the door is detected, and the detected value is used as the humidity value inside the door.

[0140] Using the humidity value of the gas at the steam outlet of the door as the humidity value inside the door helps determine whether the steam channel is capable of condensing and cooling the steam entering it. If the humidity value inside the door is high, it indicates that the condensation effect of the steam channel is relatively poor, or that the steam content inside the door channel is too high, preventing the channel from effectively condensing the steam. This results in a large amount of steam being discharged from the door channel, which can easily cause the floor to become slippery or create excessive moisture inside the cabinet where the cooking equipment is installed, making it unsuitable for use. Therefore, the door handle should be extended to allow the steam to be discharged directly through the upper space of the door to the front space. Since the front space of the door assembly is relatively large, even if a large amount of steam is discharged, it can quickly dissipate to other areas, preventing excessive water stains on the floor or in the cabinet and improving the user experience of the cooking equipment.

[0141] In this embodiment, a second gas humidity detection device is installed at the lower end of the door to detect the humidity value inside the door.

[0142] In this embodiment, the control method further includes: after switching the door handle to the extended state due to an abnormal operating state, determining whether the abnormal operating state has been eliminated; if so, controlling the door handle to switch to the retracted state.

[0143] Specifically, the control method further includes: when the door handle switches to the extended state because the handle temperature value is higher than the first preset temperature value, if the handle temperature value is less than or equal to the second preset temperature value and the exhaust humidity value is higher than the first preset exhaust humidity value, then the door handle is controlled to switch to the retracted state, and the second preset temperature value is lower than or equal to the first preset temperature value.

[0144] In other words, when the handle temperature is higher than the first preset temperature, it indicates that the handle is too hot and the handle needs to be switched to the extended state to dissipate heat and cool down. When the handle temperature drops to the second preset temperature, it is necessary to determine whether it is in a second abnormal working state, that is, whether the exhaust humidity is higher than the first preset exhaust humidity. If so, the handle can be switched to the retracted state to maintain normal operation of the cooking process. If not, the handle remains in the extended state to avoid the problem of the handle immediately switching back to the extended state due to the second abnormal working state when the handle is switched to the retracted state after the first abnormal working state is eliminated. This avoids frequent switching of the handle, reduces the cost of the cooking equipment, and improves the user experience of the cooking equipment.

[0145] The control method also includes: during the cooking process, when the door handle switches to the extended state because the exhaust humidity value is lower than the first preset exhaust humidity value, if the duration of the exhaust humidity value being higher than the first preset exhaust humidity value is longer than the preset duration, the door handle is controlled to switch to the retracted state.

[0146] When the exhaust humidity value is lower than the first preset exhaust humidity value, it indicates that the cooking state may be baking or other non-steaming cooking methods. In this case, to prevent excessive grease from entering the door, the door handle needs to be extended. When the exhaust humidity value is equal to or higher than the first preset exhaust humidity value, it indicates that the cooking state has switched to steaming. Therefore, the door handle can be retracted to allow the cooking equipment to operate normally. By determining whether the exhaust humidity value is equal to or higher than the first preset exhaust humidity value for a duration equal to or higher than the preset duration, the deviation in detection results caused by occasional increases in exhaust humidity value, single-point detection errors in exhaust humidity value, or other reasons can be eliminated, improving detection accuracy and thus improving the control accuracy of the cooking equipment.

[0147] In this embodiment, the preset duration is preferably 2s to 20s.

[0148] In this embodiment, the control method further includes: when the door handle switches to the extended state because the humidity value inside the door is greater than the first preset humidity value inside the door, if the humidity value inside the door is less than the second preset humidity value inside the door, the door handle is controlled to switch to the retracted state, and the second preset humidity value inside the door is less than or equal to the first preset humidity value inside the door.

[0149] When the humidity value inside the door is greater than the first preset humidity value inside the door, it indicates that the amount of steam in the steam passage of the exhaust door is large, which is likely to form water stains on the ground below the door or inside the cabinet. Therefore, it is necessary to switch the door handle to the extended state to change the steam exhaust path. When the humidity value inside the door decreases to the second preset humidity value, it indicates that the third abnormal working state has been eliminated, and the door handle can be switched to the retracted state.

[0150] Preferably, if the humidity value inside the door is less than or equal to the second preset humidity value inside the door, and the exhaust humidity value is equal to or greater than the first preset exhaust humidity value but less than the first preset exhaust humidity value, it indicates that the amount of steam discharged from the inner pot is reasonable and the cooking equipment is in normal cooking state. The door handle should be switched to the retracted state to allow steam to enter the door steam channel. This also avoids the large amount of steam discharged from the inlet of the door steam channel, which would cause the exhaust humidity value to rise rapidly to the first preset humidity value inside the door, resulting in frequent switching of the door handle between the extended and retracted states, thus improving the user experience of the cooking equipment.

[0151] Example 3

[0152] This embodiment provides a cooking device and a control method for the cooking device. The control method provided in this embodiment is a further improvement based on the above embodiments, and the above embodiments will not be described again in this embodiment.

[0153] In this embodiment, the cooking device is equipped with a fan assembly and a cold air inlet duct. The control method further includes:

[0154] During the cooking process, when the door handle is in the retracted state, the fan assembly is controlled to operate, so that the fan assembly guides the external cooling airflow through the cold air inlet channel, the upper steam channel and the door steam channel in sequence before flowing out.

[0155] In this embodiment, the air pressure generated by the operation of the fan assembly causes the gas in the inner liner to flow through the steam outlet sequentially through the steam channel and the upper steam channel of the machine body. The fan assembly also causes the external cooling airflow to enter the upper steam channel through the cold air inlet channel and mix with the steam. This allows the cooling airflow to dissipate heat from the steam, enabling the steam to be quickly condensed and cooled, improving the steam condensation effect, and reducing the steam emission and steam discharge temperature.

[0156] In this embodiment, the cold air intake duct includes a door intake duct located inside the machine door and a body intake duct located inside the machine body. The body intake duct is separated from the body steam duct, while the door intake duct is separated from the door steam duct but thermally connected. The fan assembly includes a main fan located inside the machine body. The main fan's air inlet is connected to the body intake duct, and the main fan's air outlet is connected to the body steam duct. In other embodiments, the cold air intake duct may not pass through the inside of the machine door.

[0157] Control methods include:

[0158] When the door handle is extended, the main fan runs to control the cooling airflow to flow sequentially through the door air inlet channel, the machine body air inlet channel, the main fan and the machine body steam channel before flowing out of the front of the door;

[0159] When the door handle is in the retracted position, the main fan runs to control the cooling airflow to flow sequentially through the door air inlet channel, the body air inlet channel, the main fan, the body steam channel, the upper steam channel, and the door steam channel before flowing out.

[0160] In this embodiment, a steam emission device is provided between the inner liner and the casing. The steam emission device includes an exhaust hood and the aforementioned main fan. The exhaust hood has a separate steam passage and an air inlet passage. The main fan is installed on the exhaust hood. The steam emission device is preferably located at the top of the inner liner.

[0161] In this embodiment, a cold air outlet is provided on the top rear side of the door, and the door air inlet channel is connected to the machine body air inlet channel through the cold air outlet. That is, steam enters the door steam channel from the top of the door downwards, and cold air flows out of the door from the upper rear side, thereby avoiding the problem of airflow mixing at the door handle.

[0162] Example 4

[0163] This embodiment provides a cooking device and a control method for the cooking device. The cooking device and control method provided in this embodiment are further improvements based on Embodiment 3. This embodiment will not repeat the same content as Embodiment 3.

[0164] In this embodiment, the operating power of the fan assembly can be adjusted, thereby allowing the intake air volume of the fan assembly to be adjusted.

[0165] like Figure 2 As shown, the control method provided in this embodiment further includes:

[0166] When the humidity inside the door is lower than the third preset humidity inside the door, the control fan assembly is operated at the first air intake volume, and the third preset humidity inside the door is lower than the first preset humidity inside the door.

[0167] When the humidity inside the door is equal to or higher than the third preset humidity inside the door, the control fan assembly operates at the second air intake volume, which is higher than the first air intake volume.

[0168] In this embodiment, when the door handle is extended or retracted and the humidity inside the door is lower than the third preset humidity inside the door, it indicates that the amount of steam in the exhaust steam channel will not be too high. At this time, the fan assembly operates with the first air intake volume, which can meet the needs of steam discharge and steam condensation, save the energy consumption of the fan assembly, reduce the operating costs of the fan assembly and cooking equipment, and also reduce the noise of the cooking equipment during operation. When the humidity inside the door is equal to or higher than the third preset humidity inside the door, it indicates that the condensation effect of the door steam channel on the steam is not good, and the amount of steam in the exhaust steam channel is large. Therefore, by increasing the air intake volume of the fan assembly to the second air intake volume, the airflow of the cooling airflow entering the cold air intake channel can be increased, thereby increasing the cooling airflow entering the door steam channel, improving the condensation effect on the steam, and thus reducing the amount of steam in the exhaust steam channel.

[0169] That is, in this embodiment, the control method includes the following steps:

[0170] Step S401: Start the cooking equipment;

[0171] Step S402: Determine whether it is in steam mode. If not, proceed to step S403. If yes, proceed to step S405.

[0172] Step S403: Control the door handle to be in the extended state;

[0173] Step S404: Control the fan assembly to operate at the first intake air volume;

[0174] Step S405: Control the door handle to be in the retracted state;

[0175] Step S406: Control the fan assembly to operate at the first intake air volume;

[0176] Step S407: Detect the operating parameter values;

[0177] Step S408: Determine whether the running state is abnormal based on the running parameter values. If yes, proceed to step S411; otherwise, proceed to step S409.

[0178] Step S409: Determine whether the humidity value inside the door is equal to or higher than the third preset humidity value inside the door. If yes, proceed to step S410; otherwise, return to step S406.

[0179] Step S410: Control the fan assembly to operate at the second intake air volume;

[0180] Step S411: Switch the door handle to the extended position.

[0181] It is understandable that steps S403 and S405 can be performed simultaneously, and steps S405, S406 and S407 can be performed simultaneously.

[0182] In this embodiment, a steam exhaust device is provided between the inner liner and the casing. The steam passage of the machine body includes a steam exhaust channel located within the steam exhaust device. The cold air inlet passage includes a machine body inlet passage located within the steam exhaust device. The fan assembly includes a main fan and a door fan. The air inlet of the main fan is connected to the machine body inlet passage, and the air outlet of the main fan is connected to the steam exhaust channel. The door fan is used to guide the cooling airflow into the machine body inlet passage or to guide the airflow out of the door steam passage.

[0183] The control method provided in this embodiment also includes:

[0184] When the humidity inside the door is lower than the third preset humidity value, the main fan is controlled to start running until the door fan is kept closed. When the humidity inside the door is equal to or higher than the third preset humidity value, both the main fan and the door fan are controlled to start running.

[0185] That is, in this embodiment, when the humidity value inside the door is lower than the third preset humidity value inside the door, only the main fan starts to run, and the air intake volume of the main fan is the first air intake volume; when both the door fan and the main fan are running, the overall operating power of the fan assembly increases, and the air intake volume of the fan assembly is the second air intake volume.

[0186] By installing a door fan at the machine door to guide the cooling airflow into the machine's air inlet channel or to guide the airflow out of the door steam channel, the steam exhaust channel or the cold air inlet channel can have two separate air pressure application positions, realizing fan relay between the main fan and the door fan, effectively improving the operating performance of the fan components.

[0187] Example 5

[0188] This embodiment provides a cooking device and a control method for the cooking device, and the control method for the cooking device provided in this embodiment is a further improvement on the control method provided in the above embodiment.

[0189] In this embodiment, the control method further includes: when the remaining cooking time is less than or equal to the remaining preset time, controlling the door handle to be in the extended state.

[0190] This design allows the door handle to extend as cooking nears its end, enabling rapid heat dissipation and keeping its temperature within a comfortable range for user touch. This reduces the likelihood of burns from an overheated handle and improves the safety of the cooking equipment. Furthermore, the extended door handle makes it easier for users to grip and operate the door assembly after cooking.

[0191] To prevent the door handle from remaining in the extended state for an extended period after cooking, which could cause the user to bump into it, in this embodiment, the control method further includes: when cooking is finished and the temperature of the door handle is equal to or lower than a second preset temperature, controlling the door handle to switch from the extended state to the retracted state.

[0192] In other embodiments, the control method further includes: keeping the door handle in the extended state for a first preset time period after cooking is completed; and controlling the door handle to retract if it is in the extended state after the first preset time period after cooking is completed. This setting can also prevent the door handle from being in the extended state for a long time.

[0193] It is understood that the control method provided in this embodiment is applicable to further improvements of any one of the control methods in Embodiments 1 to 4.

[0194] Example 6

[0195] This embodiment provides a cooking device, which is a further improvement on the cooking device provided in any of the above embodiments. The cooking device provided in this embodiment can be controlled and operated using any of the control methods in Embodiments 1 to 5.

[0196] like Figures 3 to 5 As shown, in this embodiment, the cooking equipment includes a steam exhaust device 200 disposed between the inner pot 300 and the casing 400. The steam exhaust device 200 includes a main fan 220 and an exhaust hood 210. The exhaust hood 210 has a separate steam exhaust channel 2101 and a body air inlet channel 2102. The body steam channel includes the steam exhaust channel 2101, which is connected to the steam exhaust port. The cold air inlet channel includes the body air inlet channel 2102. The main fan 220 is installed at the exhaust hood 210, and the air inlet of the main fan 220 is connected to the body air inlet channel 2102, while the air outlet of the main fan 220 is connected to the steam exhaust channel 2101.

[0197] The machine door 4 is equipped with a door air inlet channel 30 that is separated from the door steam channel 20. The cold air inlet channel includes the door air inlet channel 30 located inside the machine door 4. The door air inlet channel 30 is separated from the door steam channel 20 and is thermally connected. The lower end of the door air inlet channel 30 forms the air inlet of the cold air inlet channel. The upper end of the door air inlet channel 30 is connected to the machine body air inlet channel 2102. The door fan 7 is installed in the door air inlet channel 30.

[0198] A cold air outlet 40 is provided at the rear top of the door 4. The lower end of the door air inlet channel 30 forms the air inlet of the cold air inlet channel, and the upper end of the door air inlet channel 30 is connected to the body air inlet channel 2102 through the cold air outlet 40. The body air inlet channel 2102 is located below the steam exhaust channel 2101. That is, steam enters the door steam channel 20 from the top of the door 4 downwards, and the cooling airflow in the door air inlet channel 30 flows backwards out of the cold air outlet 40, thereby avoiding airflow interference.

[0199] The machine door 4 includes an outer door 41 and an inner door 42 spaced apart inside the outer door 41. The machine door 4 also includes door supports 43, two of which are spaced apart in the left-right direction and sandwiched between the inner door 42 and the outer door 41. The inner door 42, outer door 41, and the two door supports 43 together form an interior space. The machine door 4 has an observation window, with the door supports 43 located outside the observation window to prevent their structure from being exposed to the user's view, thus avoiding a deterioration in the aesthetics of the machine door assembly 100 and the cooking equipment. The lower end of the inner door 42 is wrapped with an elastic strip 44 to prevent the machine door 4 from colliding hard with the machine body during opening and closing. The specific structure of the machine door 4 can be designed with reference to existing technology; this is not the focus of this invention, and this embodiment will not limit or elaborate on it.

[0200] In this embodiment, the steam passage 20 is located outside the observation window, thereby reducing the impact of steam condensation and discharge on the observation window. Preferably, steam passages 20 are respectively provided on the left and right sides of the observation window, thereby increasing the channels for steam discharge inside the machine door 4, reducing steam discharge resistance, and improving steam discharge efficiency. In other embodiments, the steam passage 20 may also pass through the observation window.

[0201] To separate and form a door steam passage 20 and a door air inlet passage 30 in the machine door 4, an air duct separation component 3 is provided inside the machine door 4. The air duct separation component 3 is sandwiched between the inner door 42 and the outer door 41, and the air duct separation component 3, the inner door 42 and the outer door 41 together form an inner door air duct. The door steam passage 20 and the door air inlet passage 30 are located in the inner door air duct.

[0202] In this embodiment, the door steam channel 20 is disposed inside the door handle 1, which facilitates the setting of the shape, position, and size of the upper steam channel 10. This makes the setting position of the upper steam channel 10 more compatible with the position and shape of the door steam channel 20, improving the flexibility of the setting position of the upper steam channel 10. Specifically, one door steam channel 20 is provided on each of the left and right sides of the observation window, and upper steam channels 10 are respectively provided at the left and right ends of the door handle 1. This ensures that the upper steam channel 10 and the door steam channel 20 are set in a one-to-one correspondence, improving the smoothness of communication between the upper steam channel 10 and the door steam channel 20.

[0203] In other embodiments, the upper steam passage 10 may also be formed by the top of the door handle 1 and the top of the door 4. Specifically, the door handle 1 includes a handle panel 12 extending in the left-right direction. When the door handle 1 is in the retracted state, the lower end of the handle panel 12 extends to the top of the door 4, and the upper end of the handle panel 12 is used to cooperate with the control device 500 on the upper side of the door assembly 100, so that the rear side of the handle panel 12, the top of the door 4, and the control device 500 form an upper steam passage 10.

[0204] In this embodiment, one door steam channel 20 is provided on each of the left and right sides of the observation window, and an upper steam channel 10 is provided on each of the left and right ends of the door handle 1, thereby making the upper steam channel 10 and the door steam channel 20 correspond one-to-one, improving the smoothness of the connection between the upper steam channel 10 and the door steam channel 20.

[0205] Furthermore, a handle groove 112 is provided through the door handle 1, and two upper steam channels 10 are respectively located on the left and right sides of the handle groove 112. By providing a handle groove 112 on the door handle 1, the convenience of the user holding the door handle 1 can be improved, and the ease of operation of the door assembly 100 can be improved; by setting the two upper steam channels 10 on the left and right sides of the handle groove 112 respectively, interference between the upper steam channels 10 and the handle groove 112 can be effectively avoided.

[0206] In this embodiment, the front and rear sides of the handle groove 112 are closed, and a connecting groove 111 is provided on the rear side of the door handle 1. The two ends of the connecting groove 111 are respectively connected to the two upper steam channels 10. That is, the connecting groove 111 extends in the left and right direction and is located on the rear side of the handle groove 112. The handle rear air vent 115 is set at the bottom of the connecting groove 111. The setting of the connecting groove 111 can reduce the alignment accuracy between the handle rear air vent 115 and the steam exhaust channel 2101, ensuring that the steam in the steam exhaust channel 2101 can enter the upper steam channel 10 through the connecting groove 111, which is conducive to the convenience of communication between the upper steam channel 10 and the steam exhaust channel 2101.

[0207] In other embodiments, the handle groove 112 can penetrate the rear sidewall of the door handle 1, thereby making the door handle 1 have a U-shaped structure with the opening facing backward, simplifying the structure of the door handle 1 and reducing the processing difficulty of the door handle 1.

[0208] The upper steam passage 10 is L-shaped, comprising a horizontal passage 101 extending forward and backward and a vertical passage 102 extending along the height of the door 4. The rear end of the horizontal passage 101 forms a handle rear air vent 115, and the front end communicates with the upper end of the vertical passage 102. The lower end of the vertical passage 102 forms a handle lower air vent 116. This arrangement allows the handle rear air vent 115 to be positioned close to the front of the door 4, thus facilitating that when the door handle 1 is extended, the handle lower air vent 116 is located on the front of the door 4.

[0209] The door handle 1 includes a handle body 11 and a handle panel 12 disposed on the front side of the handle body 11. The handle body 11 is provided with an upper steam passage 10 and a handle groove 112. The handle panel 12 enhances the aesthetic appearance of the door handle 1 and better ensures that the shape of the door handle 1 is consistent with the shape of the door 4 when it is in the retracted state, thus improving the ease of cleaning the door handle 1. The left and right sides of the handle panel 12 extend outward from the handle body 11, and the left and right sides of the handle panel 12 are flush with the left and right sides of the outer door 41.

[0210] like Figures 6 to 8 As shown, to improve the ease of installation of the door handle 1 on the machine door 4, in this embodiment, the machine door assembly 100 further includes a handle bracket 2. The handle bracket 2 is installed at the top of the machine door 4, and the door handle 1 is movably installed on the handle bracket 2. The handle bracket 2 simplifies the structure of the machine door 4 and ensures the reliability of the door handle 1 installation. The door handle 1 is installed at the top of the air duct partition assembly 3 so that the door handle 1 blocks the air duct partition assembly 3 upwards.

[0211] In this embodiment, the door handle 1 can slide relative to the door 4 in a front-to-back direction to switch between an extended state and a retracted state. This reduces the space required for the door handle 1 to move and reduces interference between the door handle 1 and structures such as the control device 500 and the door 4. In other embodiments, the door handle 1 can also be rotatably mounted to achieve rotational switching between the extended and retracted states.

[0212] The handle bracket 2 is provided with an upper vent 211. When the door handle 1 is in the retracted state, the upper vent 211 connects the upper steam passage 10 and the door steam passage 20. That is, in this embodiment, the upper vent 211 connects the upper steam passage 10 and the door steam passage 20. By providing the upper vent 211 on the handle bracket 2, the arrangement of the handle bracket 2 can be prevented from affecting the connection between the upper steam passage 10 and the door steam passage 20.

[0213] Furthermore, when the door handle 1 is in the extended state, the upper vent 211 is closed, thereby blocking the connection between the upper steam passage 10 and the door steam passage 20. This arrangement prevents steam entering the upper steam passage 10 from entering the door steam passage 20 when the door handle 1 is in the extended state, thus effectively controlling the steam discharge path when the door handle 1 is in the extended state.

[0214] In this embodiment, two sets of upper vent holes 211 are provided, each set corresponding to one of the two door steam channels 20. Each set of upper vent holes 211 includes at least one upper vent hole 211. Thus, each upper steam channel 10 is connected to the corresponding door steam channel 20 through the upper vent holes 211 of the corresponding set. Preferably, each set of upper vent holes 211 includes multiple upper vent holes 211 spaced apart in the left-right direction. The multiple upper vent holes 211 in the same set are all connected to the corresponding door steam channel 20 and upper steam channel 10, thereby reducing the ventilation area of ​​a single upper vent hole 211 and facilitating the control of the amount of steam entering the door steam channel 20. In other embodiments, the upper vent hole 211 may also be an elongated hole extending in the left-right direction.

[0215] The handle bracket 2 includes a horizontally arranged top plate portion 21, on which the aforementioned upper ventilation hole 211 is provided. The front end of the top plate portion 21 abuts against the inner side of the outer door 41, and the top surface of the top plate portion 21 is preferably flush with the top surface of the outer door 41, so that when the door handle 1 is installed on the top plate portion 21, the lower side of the door handle 1 is close to the top of the outer door 41, thereby ensuring that when the door handle 1 is in the retracted state, there is no gap or only a small gap between the door handle 1 and the machine door 4, which is aesthetically pleasing and facilitates cleaning. Specifically, the top plate portion 21 is supported on two door brackets 43, and the door handle 1 is slidably installed on the top side of the top plate portion 21.

[0216] The handle bracket 2 also includes a mounting part 23, which protrudes from the lower side of the top plate 21 and corresponds one-to-one with the door bracket 43. The mounting part 23 and the door bracket 43 are detachably connected to improve the connection convenience between the handle bracket 2 and the door 4. The mounting part 23 and the door bracket 43 can be connected by screws, snap-fit, or other detachable connection methods, but are not limited to these.

[0217] The handle bracket 2 also includes a side panel 22, the upper end of which is vertically connected to the rear side of the top panel 21. The side panel 22 extends downward to the side of the inner door 42 opposite to the outer door 41, so as to cover and hide the upper end of the inner door 42 and the upper end of the air duct partition assembly 3, thereby improving the overall aesthetics of the door assembly 100.

[0218] In this embodiment, the air duct partition 3 divides the door air inlet channel 30 and the door steam channel 20. The air duct partition 3 closes the top of the door air inlet channel 30 to prevent the airflow in the door air inlet channel 30 from continuing to flow upward to the top of the machine door 4. The upper end of the inner door 42 is spaced from the top of the air duct partition 3 to form a cold air outlet 40, thereby reducing the difficulty of forming the cold air outlet 40 and improving the processing convenience of the machine door assembly 100. The frame side plate 22 covers the cold air outlet 40, and the frame side plate 22 has a side vent 221 that connects to the door air inlet channel 30. Thus, the flow rate of the cooling airflow can be controlled by the size, arrangement and number of the side vent 221.

[0219] Preferably, the side plate portion 22 is provided with a plurality of side ventilation holes 221 in the left and right directions, so as to reduce the size of a single side ventilation hole 221, control the flow rate through the side ventilation hole 221, and ensure the overall structural strength and rigidity of the handle bracket 2.

[0220] like Figures 9 to 11 As shown, to improve the smoothness and reliability of the sliding operation of the door handle 1, one of the door handle 1 and the handle bracket 2 is provided with a guide groove 113, and the other is provided with a guide rail 24. The guide rail 24 is slidably disposed in the guide groove 113, which extends along the thickness direction of the door 4. In this embodiment, the guide rail 24 protrudes from the top plate 21, and the guide groove 113 is provided on the door handle 1, so that the guide groove 113 is set using the height of the door handle 1, thereby improving the processing convenience of the door handle 1 and the handle bracket 2.

[0221] Furthermore, the guide groove 113 has an L-shaped structure, including a first groove and a second groove that are connected. The first groove extends along the height direction of the door 4 and passes through the lower side of the door handle 1, while the second groove extends in the left-right direction. The shape of the guide rail 24 is consistent with the shape of the guide groove 113, that is, the guide rail 24 includes a first guide and a second guide that are vertically connected. The first guide is vertically connected to the top plate 21, and the second guide is opposite to and spaced apart from the top plate 21. The first guide is slidably disposed in the first groove, and the second guide is slidably disposed in the second groove. This structural arrangement of the guide groove 113 and the guide rail 24 can prevent the door handle 1 from detaching from the handle bracket 2 in the vertical or left-right direction, thereby improving the sliding installation stability of the door handle 1 on the handle bracket 2.

[0222] In this embodiment, the door assembly 100 also includes a handle drive assembly 5, which is used to drive the door handle 1 to switch between a retracted state and an extended state, thereby enabling automated control of the door handle 1, so that the control device 500 can automatically control the operation of the door handle 1 according to the steam state in the inner tank 300.

[0223] The handle drive assembly 5 is preferably installed inside the door 4, with one on each side of the door 4, to ensure the force balance at both ends of the door handle 1 and reduce the driving force requirement for a single handle drive assembly 5, thus allowing the handle drive assembly 5 to be miniaturized. The handle drive assembly 5 is preferably located between the air duct partition assembly 3 and the door bracket 43, thereby preventing steam from interfering with the handle drive assembly 5 and improving the operational reliability of the handle drive assembly 5.

[0224] The handle drive assembly 5 includes a handle drive motor 51 and a transmission gear 52 sleeved on the output shaft of the handle drive motor 51. The axis of the transmission gear 52 is arranged along the height direction of the door 4. A rack 13 is provided on the door handle 1, which extends along the thickness direction of the door 4 and meshes with the transmission gear 52. This handle drive assembly 5 has a simple structure, low cost and weight, and small footprint, which helps to achieve a compact structure of the door assembly 100.

[0225] A drive groove 114 is provided on the lower side of the door handle 1, extending along the thickness direction of the door 4. The aforementioned rack 13 is provided on one side wall of the drive groove 114, and the transmission gear 52 extends into the drive groove 114 and meshes with the rack 13. The design of the drive groove 114 can avoid the problem of the rack 13 protruding from the lower side of the door handle 1 and interfering with the door 4 or other structures, thereby improving the operational reliability of the door handle 1 and further improving the structural compactness of the door assembly 100.

[0226] The top plate 21 has a clearance opening 212 for the transmission gear 52 to extend out. A guide rail is provided on one side wall of the clearance opening 212. This allows the material at the punching point to be bent into the guide rail portion 24 simultaneously with the processing of the clearance opening 212, improving the processing convenience of the guide rail portion 24 and reducing the processing difficulty of the handle bracket 2. Specifically, the guide groove 113 communicates with the drive groove 114, and the second groove extends in a direction away from the rack 13, thereby improving the structural compactness of the door handle 1.

[0227] Example 7

[0228] This embodiment provides a cooking device and a control method for the cooking device. The cooking device provided in this embodiment is a further improvement based on Embodiment Six, and the content that is the same as in Embodiment Six will not be described again in this embodiment. Furthermore, the cooking device provided in this embodiment can be controlled and operated using any of the control methods from Embodiments One to Five.

[0229] like Figures 12 to 17As shown, the door air inlet channel 30 includes a steam heat dissipation channel 301, which is arranged side-by-side with the door steam channel 20 and is thermally connected. Alternatively, the door air inlet channel 30 includes a door heat dissipation channel 302 passing through an observation window. The door heat dissipation channel 302 is used to dissipate heat from the main door 4 to prevent excessive steam temperature rise in the door 4. The steam heat dissipation channel 301 is used to dissipate heat from the steam in the door steam channel 20, thereby reducing the steam temperature, improving steam condensation efficiency, reducing the steam content in the exhaust door steam channel 20, and lowering the steam temperature of the exhaust door steam channel 20. In other embodiments, the door air inlet channel 30 may include only the door heat dissipation channel 302 or only the steam heat dissipation channel 301.

[0230] Specifically, in this embodiment, the door air inlet channel 30 includes two steam heat dissipation channels 301. The two steam heat dissipation channels 301 are arranged side by side with the two door steam channels 20 and are thermally connected. The door heat dissipation channel 302 is located between the two steam heat dissipation channels 301.

[0231] To improve the ease of forming the door air inlet channel 30 and the door steam channel 20, an air duct partition component 3 is provided inside the machine door 4. The air duct partition component 3 includes an air duct frame 31 and a steam pipe 33. The air duct frame 31 is sandwiched between the inner door 42 and the outer door 41, and the air duct frame 31, the inner door 42, and the outer door 41 together form an internal air duct. The steam pipe 33 is arranged in the internal air duct, and the inner cavity of the steam pipe 33 forms the door steam channel 20. In this embodiment, the steam pipe 33 and the door steam channel 20 are arranged in a one-to-one correspondence.

[0232] The air duct frame 31 includes an inner frame portion 313 and an outer frame portion 311 spaced apart outside the inner frame portion 313. Both the inner frame portion 313 and the outer frame portion 311 are sandwiched between the inner door 42 and the outer door 41. The air duct inside the door includes two side air ducts forming between the inner frame portion 313 and the outer frame portion 311, with the two side air ducts located on the left and right sides of the inner frame portion 313, respectively. The steam pipe 33 is installed in the side air ducts, and the inner space of the inner frame portion 313 is positioned directly opposite the observation window of the machine door 4. By setting the inner frame portion 313 and the outer frame portion 311, the installation of the steam pipe 33 can be positioned, ensuring that the steam pipe 33 is located outside the observation window.

[0233] The steam pipe 33 is spaced apart from the inner door 42, and the space between the steam pipe 33 and the inner door 42 forms a steam heat dissipation channel 301. The inner space of the inner frame 313 forms at least a partial door heat dissipation channel 302.

[0234] A radiator 6 is installed inside the steam heat dissipation channel 301. A door fan 7 is detachably installed at one end of the radiator 6, which facilitates the flow of cooling air through the door fan 7 to quickly remove the heat from the radiator 6 and improve the heat dissipation effect of the radiator 6.

[0235] To improve the ease of installation of the steam pipe 33, the duct frame 31 also includes a connecting plate portion 312. The connecting plate portion 312 is connected between the inner frame portion 313 and the outer frame portion 311, and the connecting plate portion 312 is fitted to the outer door 41. The steam pipe 33 is installed on the connecting plate portion 312, and the installation method can be integral molding, welding, or detachable connection. In other embodiments, the connecting plate portion 312 may share a partial structure with the front wall of the steam pipe 33.

[0236] The outer frame 311 has an inverted U-shaped structure, meaning that the top of the outer frame 311 closes the top of the door steam passage 20 and the top of the steam heat dissipation passage 301. An air inlet group is provided at the top of the outer frame 311, with each air inlet group corresponding to one of the door steam passages 20. Each air inlet group includes several steam inlet holes 3111. When the door handle 1 is in the retracted state, steam enters the door steam passage 20 through the steam inlet holes 3111. This allows for control of the amount and speed of steam entering the door steam passage 20 by adjusting the total opening area and position of the steam inlet holes 3111.

[0237] The inner frame 313 has a U-shaped structure with the opening facing downwards. Side air ducts are formed between the left and right sides of the inner frame 313 and the left and right sides of the outer frame 311. Top air duct 303 is formed between the top of the inner frame 313 and the top of the outer frame 311. The top air duct 303 is connected to the side air ducts.

[0238] In this embodiment, the top of the inner frame 313 has several air duct connection ports 3131. The door heat dissipation channel 302 is connected to the top air duct 303 through the air duct connection ports 3131, thereby allowing the cooling airflow from the steam heat dissipation channel 301 and the door heat dissipation channel 302 to converge at the top air duct 303, facilitating the connection between the door air inlet channel 30 and the body air inlet channel 2102. Preferably, multiple air duct connection ports 3131 are spaced apart in the left-right direction, thereby ensuring the uniformity of the cooling airflow from the door heat dissipation channel 302 to the top channel. The air duct connection ports 3131 are elongated slot-shaped structures extending in the left-right direction.

[0239] In other embodiments, the outer frame 311 has an inverted U-shaped structure, and the inner frame 313 includes two inner frame plates that are opposite to each other and spaced apart, with the top of the inner frame plates abutting against the top of the outer frame 311. That is, the top air duct 303 is not provided on the air duct frame 31, and the upper end of the steam heat dissipation channel 301 and the upper end of the door steam channel 20 are respectively connected to the cold air outlet 40.

[0240] A partition plate 32 is installed on the inner side of the inner frame 313. The area of ​​the partition plate 32 facing the observation window is transparent. The partition plate 32 is spaced apart from both the outer door 41 and the inner door 42. The internal space of the inner frame 313 is divided into a partition cavity and a door heat dissipation channel 302 by the partition plate 32. The air duct connection port 3131 is connected to the door heat dissipation channel 302.

[0241] In this embodiment, the door heat dissipation channel 302 is located on one side of the inner door 42 of the partition plate 32, thereby making the door heat dissipation channel 302 located on the side of the partition plate 32 away from the inner liner 300, thereby reducing the impact of the high temperature in the inner liner 300 on the temperature of the cooling airflow and ensuring the cooling effect of the cooling airflow on the door 4.

[0242] The partition 32 is preferably made of a transparent heat-insulating material to avoid obstructing the user's view of the cooking cavity and to reduce heat transfer between the front and rear air ducts. The partition 32 is preferably made of glass, but can also be made of transparent plastic or other materials. In other embodiments, the partition 32 may be transparent only to the area facing the viewing window.

[0243] In this embodiment, the upper end of the outer frame 311 is higher than the top of the inner door 42, and the upper end of the inner frame 313 is lower than the upper end of the inner door 42, forming a cold air outlet 40 between the tops of the outer frame 311 and the inner door 42. Positioning protrusions 314 protrude rearward from the rear sides of both sides of the outer frame 311, and the positioning protrusions 314 support the top of the inner door 42. A rib 25 protrudes downward from the lower side of the top plate 21 of the handle bracket 2, and the rib 25 abuts against the upper end of the positioning protrusion 314. The rear sides of both the outer frame 311 and the inner frame 313 abut against the front side of the rib 25.

[0244] Example 7

[0245] This embodiment provides a cooking device, which is a further improvement based on Embodiment Six. The same content as in Embodiment Six will not be repeated here. Furthermore, the cooking device provided in this embodiment can be controlled and operated using any of the control methods from Embodiments One to Five.

[0246] In this embodiment, the door fan 7 is installed at the air inlet of the door air inlet channel 30, thereby maximizing the negative pressure at the air inlet of the door air inlet channel 30 and increasing the air volume of the door air inlet channel 30. At the same time, since the air inlet of the door air inlet channel 30 and the steam outlet of the door steam channel 20 are both located at the lower end of the machine door 4, the increase in negative pressure at the air inlet of the door air inlet channel 30 will also cause an increase in the overall negative pressure at the lower end of the machine door 4, which is more conducive to guiding the steam in the door steam channel 20 to be discharged from the door steam channel 20, thereby further improving the smoothness of steam discharge. Furthermore, since the air inlet of the door air inlet channel 30 is located at the lower end of the machine door 4, the distance between the door fan 7 and the main fan 220 can be maximized, which is more conducive to ensuring the consistency of negative pressure at various points in the air inlet and outlet channels, and better realizing the relay between the main fan 220 and the door fan 7. Moreover, installing the door fan 7 at the lower end of the machine door 4 is also conducive to the installation and maintenance of the door fan 7.

[0247] A radiator 6 is installed in the door air inlet channel 30. The door fan 7 is detachably installed at one end of the radiator 6, which facilitates the cooling airflow to flow through the radiator 6 through the door fan 7, so as to quickly remove the heat from the radiator 6 and improve the heat dissipation effect of the radiator 6.

[0248] To simplify the installation of the door fan 7, the radiator 6 includes multiple heat dissipation fins 61 arranged side-by-side and spaced apart. A vertically penetrating airflow channel 64 is formed between adjacent heat dissipation fins 61. The two outermost heat dissipation fins 61 each extend outwards with extension plates 62, and the door fan 7 is installed between the two extension plates 62. This arrangement allows for the installation of the door fan 7 using the structure of the radiator 6, eliminating the need for additional structures inside the door 4 for installing the door fan 7, thus simplifying the door assembly 100 structure and reducing costs. Simultaneously, this arrangement better ensures the relative positional accuracy between the door fan 7 and the radiator 6, and facilitates the assembly of the radiator 6 and door fan 7 before installation inside the door 4, improving the disassembly and assembly efficiency and precision of the door assembly 100.

[0249] Furthermore, a mounting plate 63 connects the two extension plates 62. The door fan 7 is detachably mounted on the mounting plate 63. The mounting plate 63 has a through-hole 631, which corresponds one-to-one with the door fan 7. By setting the mounting plate 63, the installation convenience of the door fan 7 can be further improved, and it is also convenient to realize the installation positioning of the door fan 7 relative to the radiator 6 in the height direction of the door 4, thereby improving the installation accuracy of the door fan 7. At the same time, by mounting the door fan 7 on the mounting plate 63, the width of the door fan 7 in the left and right direction does not need to be equal to the distance between the two extension plates 62, which improves the flexibility of door fan 7 selection and better ensures the installation reliability of the door fan 7.

[0250] Preferably, in this embodiment, each radiator 6 is provided with at least two door fans 7, which are arranged side by side in the left-right direction. This reduces the size of a single door fan 7 while increasing the maximum air intake of the door air intake channel 30. In other embodiments, each radiator 6 may be provided with one door fan 7.

[0251] In this embodiment, the door fan 7 is installed on the lower side of the mounting plate 63 to reduce interference between the door fan 7 and the heat dissipation fins 61 during installation and disassembly, thereby improving the ease of installation and disassembly of the door fan 7. The mounting plate 63 is spaced apart from the other heat dissipation fins 61 to buffer the cooling airflow from the door fan 7 to the airflow channel 64. In other embodiments, the door fan 7 may also be installed on the upper side of the mounting plate 63.
