Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a cooking device and its control method. Background Technology

[0002] As people's living standards improve, users' demands for home cooking are also gradually increasing. Users expect to cook better quality food using cooking equipment, while also wanting to extend the lifespan of that equipment.

[0003] Currently, steam ovens primarily rely on cooling fans for external heat dissipation, while internally, they also rely on cooling fans in conjunction with pressure relief vents for pressure release. Using low-speed cooling fans with small pressure relief vents may impair the heat dissipation effect of the cooking equipment, causing gas in the cooking cavity to escape through weak points in the seal between the cooking cavity and the door. Furthermore, excessively high temperatures within the cooking cavity may reduce the lifespan of internal components. Conversely, using high-speed cooling fans with large pressure relief vents may affect the heating performance of the cooking equipment.

[0004] Gases in the cooking chamber may escape through weak points in the seal between the chamber and the door, potentially causing condensation on the internal components. This condensation can lead to short circuits or corrosion of components, reducing the lifespan of the cooking equipment. Therefore, extending the lifespan of cooking equipment while maintaining its cooking performance is a pressing issue that needs to be addressed. Summary of the Invention

[0005] This application provides a cooking device and its control method, which can extend the service life of the cooking device while ensuring the cooking effect.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] In a first aspect, this application provides a cooking device, comprising: a housing having a heat dissipation duct and a cooking chamber with an opening on one side; a cooking chamber spaced apart from the heat dissipation duct, with a pressure relief port formed on the side wall of the cooking chamber near the heat dissipation duct for connecting the cooking chamber and the heat dissipation duct; a door located at the opening of the cooking chamber for covering the opening; a steam generator with its outlet connected to the cooking chamber via a pipe; a heat dissipation fan with its exhaust port connected to the heat dissipation duct for dissipating heat from the cooking chamber; and further comprising: a temperature detection device located inside the cooking chamber; a pressure detection device located inside the cooking chamber; and a steam flow detection device located on the pipe for detecting the steam generator flow rate. The system includes: a generated steam flow rate; a baffle plate located at the pressure relief port, movable between a first position and a second position, wherein the baffle plate closes the pressure relief port in the first position and opens the pressure relief port in the second position; and a controller configured to: acquire a first pressure value in the cooking chamber via a pressure detection device and acquire a steam flow rate value generated by the steam generator within a preset time period via a steam flow detection device when the steam generator is in operation; adjust the position of the baffle plate based on the first pressure value and the steam flow rate value generated within the preset time period; acquire a first temperature value in the cooking chamber via a temperature detection device after adjusting the position of the baffle plate; and adjust the speed of the cooling fan based on the first temperature value and the adjusted position of the baffle plate.

[0008] The technical solution provided in this application offers at least the following beneficial effects: When the steam generator is in operation, the pressure in the cooking chamber may be too high. In this case, the position of the baffle is adjusted based on the obtained pressure value in the cooking chamber and the steam flow rate generated by the steam generator within a preset time. It should be understood that adjusting the baffle position based on the first pressure value and the amount of steam generated within the preset time helps ensure the pressure relief effect of the cooking equipment when pressure relief is required in the cooking chamber, thereby preventing gas in the cooking chamber from escaping through weak points in the seal between the cooking chamber and the door, and preventing it from escaping outside the cooking chamber. It also helps prevent the heating effect of the cooking equipment from being affected by an excessively large opening of the pressure relief port when pressure relief is not required in the cooking chamber.

[0009] Furthermore, adjusting the fan speed based on the adjusted position of the baffle and the temperature in the cooking cavity helps ensure the heat dissipation effect of the cooking equipment.

[0010] In summary, the technical solution provided in this application helps ensure the pressure relief and heat dissipation effect of the cooking equipment, thereby helping to avoid excessively high temperatures in the cooking cavity due to poor heat dissipation.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, when describing pipelines, the terms "connected" and "linked" as used in this application have the meaning of establishing electrical connection. The specific meaning needs to be understood in conjunction with the context.

[0046] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0047] Current cooking equipment may have excessively strong pressure relief, which could affect its heating performance and thus the cooking effect. Alternatively, if the pressure relief is too weak, it may fail to release pressure and dissipate heat in the cooking chamber in time, causing gas to escape from the weak seals of the cooking chamber and door, forming condensation inside the equipment and affecting its lifespan.

[0048] Based on this, this application proposes a cooking device that adjusts the position of a baffle according to the pressure value of the cooking chamber and the steam flow rate generated by the steam generator within a preset time, and adjusts the speed of the cooling fan according to the adjusted position of the baffle and the temperature value in the cooking chamber. This helps to ensure the heating effect of the cooking device while ensuring the pressure relief and heat dissipation effect of the cooking device, thereby helping to extend the service life of the cooking device while ensuring the cooking effect.

[0049] To further describe the solution of this application, taking an oven as an example, and in conjunction with the accompanying drawings, a cooking device provided by an embodiment of this application will be described.

[0052] In some embodiments, the housing 101 has a heat dissipation duct and a cooking chamber with an opening on one side. The cooking chamber is spaced apart from the heat dissipation duct, and a pressure relief port for connecting the cooking chamber and the heat dissipation duct is formed on the side wall of the cooking chamber near the heat dissipation duct.

[0053] In some embodiments, there may be one or more pressure relief ports; the opening area and number of pressure relief ports are set according to actual needs, and this application does not impose specific restrictions on them.

[0054] In some embodiments, the door 102 is disposed at the opening of the cooking cavity to cover the opening of the cooking cavity.

[0055] In some embodiments, the control panel 103 is placed on the housing 101, above the door 102.

[0056] In some embodiments, the user can send control commands to the cooking device through the control panel 103; the control panel 103 may be a touch panel or a mechanical panel, etc., and this application does not make specific limitations on it.

[0057] See Figure 2 As shown, the cooking device provided in this application embodiment may further include a steam generator 104; the steam outlet of the steam generator 104 is connected to the cooking chamber through a pipe.

[0058] In some embodiments, the steam generator 104 may be disposed on the housing 101 or on the outside of the cooking cavity. The embodiments of this application do not impose specific restrictions on the location of the steam generator 104.

[0059] In some embodiments, a steam generator 104 is used to generate steam.

[0060] In some embodiments, the steam generated by the steam generator 104 enters the cooking chamber through a pipe, which can provide a humid environment for the cooking chamber and prevent the food in the cooking chamber from drying out excessively.

[0061] In other embodiments, the steam generated by the steam generator 104 enters the cooking chamber through a pipe, and the food can be surrounded by steam during the heating process, thereby achieving the effect of steaming or cooking.

[0062] See Figure 3 As shown, the cooking equipment provided in this application embodiment may further include a cooling fan 105 and a heating device 106.

[0063] In some embodiments, the cooling fan 105 may be a cooling fan with multiple speed settings, each with a different power output. This application does not impose any specific limitations on this.

[0064] In some embodiments, the cooling fan 105 may be disposed on the top of the housing 101, and this application does not impose any specific limitations on this.

[0065] In some embodiments, the exhaust port of the cooling fan 105 is connected to the cooling duct; the cooling fan 105 can be used to dissipate heat for the cooking cavity, and can also be used to dissipate heat for components outside the cooking cavity, and this application does not make specific limitations in this regard.

[0066] In one possible implementation, see Figure 4 As shown, the cooling fan 105 can be a dual-speed cooling fan. The cooling fan 105 is located on the top of the housing 101, which includes a cooking cavity.

[0067] In some embodiments, the heating device 106 may be disposed at the top and / or bottom of the housing 101 for heating food in the cooking cavity.

[0068] See Figure 5 As shown, the cooking device provided in this application embodiment may further include a baffle 107.

[0069] In some embodiments, a baffle 107 is disposed at a pressure relief port; the baffle 107 may be a baffle that moves between a first position and a second position via a slide rail.

[0070] In some embodiments, when the baffle 107 is moved to the first position, the pressure relief port is closed; when the baffle 107 is moved to the second position, the pressure relief port is open. The pressure relief port is partially open when the baffle 107 is in either the first or second position.

[0071] See Figure 6 As shown, the cooking equipment provided in this application embodiment may further include a temperature detection device 108, a pressure detection device 109, a steam flow detection device 110, and a controller 111. The controller 111 is electrically connected to the temperature detection device 108, the pressure detection device 109, and the steam flow detection device 110, respectively.

[0072] In some embodiments, the temperature detection device 108 is used to detect the temperature in the cooking cavity. The temperature detection device 108 is disposed on the cooking cavity.

[0073] In some embodiments, the temperature detection device 108 may be a thermistor, a thermocouple, or a temperature sensor, and this application does not impose specific limitations on this. Taking a thermistor as an example, the working principle of a thermistor is based on the characteristic that the resistance of a material changes with temperature. By measuring the change in resistance, the change in temperature is calculated.

[0074] In some embodiments, a pressure detection device 109 is used to detect the pressure in the cooking cavity. The pressure detection device 109 is disposed on the cooking cavity.

[0075] In some embodiments, the pressure detection device 109 may be a pressure sensor, which works by measuring pressure by sensing the change in the resistance of a material as pressure changes.

[0076] In one possible implementation, see Figure 7 As shown, the temperature detection device 108 and the pressure detection device 109 can be respectively installed on the top of the cooking cavity.

[0077] In some embodiments, the steam flow detection device 110 may be installed on the first pipeline, and this application does not impose specific limitations on this.

[0078] In some embodiments, the steam flow detection device 110 is used to record the amount of steam generated by the steam generator 104 or the amount of water consumed.

[0079] In some embodiments, the steam flow detection device 110 may be an air-driven flow meter, a magnetic turbine flow meter, an ultrasonic flow meter, or a vortex flow meter, and this application does not impose specific limitations on this. Taking a magnetic turbine flow meter as an example, the working principle of a magnetic turbine flow meter is to measure the flow rate by means of the rotating turbine blades generated when steam flows through it.

[0080] In some embodiments, see Figure 8 The controller 111 is also electrically connected to the control panel 103, the steam generator 104, the cooling fan 105, the heating device 106, and the baffle 107.

[0081] In some embodiments, controller 111 refers to a device that can generate operation control signals according to instruction opcodes and timing signals to instruct the cooking equipment to execute control instructions. Exemplarily, controller 111 can be a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. Controller 111 can also be other devices with processing functions, such as circuits, devices, or software modules; this application embodiment does not impose any limitations on this.

[0082] In some embodiments, the cooking device also includes a communicator connected to the controller 111 for establishing communication connections with other network entities. For example, an RF module can be used for signal reception and transmission; specifically, it can send received information to the controller 111 for processing and also transmit signals generated by the controller. Typically, the RF circuit may include, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier (LNA), a duplexer, etc.

[0083] For example, cooking equipment can receive control commands sent by terminal devices through a communicator, and perform corresponding processing according to the control commands to realize interaction between users and cooking equipment.

[0084] Figure 9 This is a schematic diagram illustrating the interaction between an oven controller 111 and a terminal device according to an exemplary embodiment of this application.

[0085] like Figure 9 As shown, the terminal device can establish a communication connection with the oven's controller 111. Exemplarily, any known network communication protocol can be used to establish this connection. This network communication protocol can be various wired or wireless communication protocols, such as Ethernet, Universal Serial Bus (USB), FireWire, any cellular network communication protocol (e.g., 3G / 4G / 5G), Bluetooth, Wireless Fidelity (Wi-Fi), NFC, or any other suitable communication protocol. The communication connection can be a Bluetooth connection, NFC, Zigbee, Wireless Fidelity (Wi-Fi), etc. This application does not impose specific limitations in this regard.

[0086] It should be noted that, Figure 9 The terminal device shown is merely an example. The terminal device in this application can be a remote control, mobile phone, tablet computer, personal computer (PC), personal digital assistant (PDA), smartwatch, netbook, wearable electronic device, augmented reality (AR) device, virtual reality (VR) device, robot, etc. This application does not impose any special restrictions on the specific form of the terminal device.

[0087] In some embodiments, the controller 111 is configured to: when the steam generator is in operation, acquire a first pressure value in the cooking cavity via a pressure detection device, and acquire a steam flow rate value generated by the steam generator within a preset time period via a steam flow detection device; adjust the position of the baffle based on the first pressure value and the steam flow rate value generated within the preset time period; after adjusting the position of the baffle, acquire a first temperature value in the cooking cavity via a temperature detection device; and adjust the speed of the cooling fan based on the first temperature value and the adjusted position of the baffle.

[0088] As can be seen from the above, the technical solution provided in this application brings at least the following beneficial effects: When the steam generator is in operation, the pressure value in the cooking chamber may be too high. At this time, the position of the baffle is adjusted according to the obtained pressure value in the cooking chamber and the steam flow rate generated by the steam generator within a preset time. It should be understood that adjusting the position of the baffle according to the first pressure value and the amount of steam generated within the preset time helps to ensure the pressure relief effect of the cooking equipment when the cooking chamber needs to be depressurized, thereby preventing gas in the cooking chamber from escaping from the weak sealing points between the cooking chamber and the door, and thus outside the cooking chamber; it also helps to prevent the heating effect of the cooking equipment from being affected by the excessively large opening of the pressure relief port when the cooking chamber does not need to be depressurized.

[0089] Furthermore, adjusting the fan speed based on the adjusted position of the baffle and the temperature in the cooking cavity helps ensure the heat dissipation effect of the cooking equipment.

[0090] In summary, the technical solution provided in this application helps ensure the pressure relief and heat dissipation effect of the cooking equipment, thereby helping to avoid excessively high temperatures in the cooking cavity due to poor heat dissipation. It also helps to prevent gas from the cooking cavity from spreading into the interior of the cooking equipment and forming condensation, thus ensuring the service life of the cooking equipment. Simultaneously, the technical solution provided in this application also ensures the heating effect of the cooking equipment, achieving the goal of extending the service life of the cooking equipment while guaranteeing its cooking efficiency.

[0091] In some embodiments, when the controller 111 is configured to adjust the position of the baffle based on a first pressure value and a steam flow rate value generated within a preset time period, it is specifically configured to: adjust the baffle to a second position if a first preset condition is met; wherein the first preset condition includes the first pressure value being above a preset pressure threshold and / or the steam flow rate value generated within a preset time period being above a preset steam quantity threshold; and adjust the baffle to a third position if the first preset condition is not met, wherein the third position is located between the first position and the second position.

[0092] As described above, when the first pressure value exceeds a preset pressure threshold and / or the flow rate generated within a preset time exceeds a preset steam threshold, the pressure inside the cooking chamber is too high and / or there is too much steam. If the steam cannot be released in time, condensation may occur as the gas in the cooking chamber diffuses into the cooking equipment. It should be understood that adjusting the baffle to the second position when the pressure inside the cooking chamber is too high and / or there is too much steam helps to ensure the pressure relief effect of the cooking equipment, thereby helping to extend the service life of the cooking equipment.

[0093] Furthermore, when the first pressure value is below a preset pressure threshold and the flow rate generated within a preset time is below a preset steam threshold, i.e., when the cooking chamber does not require rapid pressure relief or rapid exhaust, the baffle is adjusted to the third position. It should be understood that adjusting the baffle to the third position, with the pressure relief port not fully open, can prevent the heating effect of the cooking equipment from being affected by an excessively large pressure relief port, thereby helping to ensure the cooking effect of the cooking equipment.

[0094] In some embodiments, when the controller 111 is configured to adjust the speed of the cooling fan according to the first temperature value and the adjusted position of the baffle, it is specifically configured to: adjust the cooling fan to the first speed when the baffle is adjusted to the second position and the first temperature value is above the first preset temperature threshold; and adjust the cooling fan to the second speed when the baffle is adjusted to the second position and the first temperature value is below the second preset temperature threshold, wherein the second preset temperature threshold is below the first preset temperature threshold.

[0095] As described above, when the baffle is adjusted to the second position and the first temperature value is above the first preset temperature threshold, it indicates that the pressure relief vent is fully open and the temperature inside the cooking cavity is high. Using the first setting of the cooling fan in this situation helps ensure the heat dissipation effect of the cooking equipment. When the baffle is adjusted to the second position and the first temperature value is below the second preset temperature threshold, it indicates that the pressure relief vent is fully open but the temperature inside the cooking cavity is normal. Using the second setting of the cooling fan in this situation helps ensure the heating effect of the cooking equipment.

[0096] In some embodiments, when the controller 111 is configured to adjust the speed of the cooling fan according to the first temperature value and the adjusted position of the baffle, it is specifically configured to: adjust the cooling fan to the first speed when the speed is adjusted to the third position and the first temperature value is above the first preset temperature threshold; and adjust the cooling fan to the second speed when the speed is adjusted to the third position and the first temperature value is below the third preset temperature threshold, wherein the third preset temperature threshold is between the first preset temperature threshold and the second preset temperature threshold.

[0097] As described above, when the baffle is adjusted to the second position and the first temperature value is above the first preset temperature threshold, the pressure relief vent is not fully open and the temperature in the cooking cavity is too high. In this case, using the first setting of the cooling fan helps ensure the heat dissipation effect of the cooking equipment. When the baffle is adjusted to the second position and the first temperature value is below the third preset temperature threshold, it indicates that the pressure relief vent is not fully open, but the temperature in the cooking cavity is normal. In this case, using the second setting of the cooling fan helps ensure the heating effect of the cooking equipment.

[0098] In some embodiments, the controller 111 is further configured to: adjust the baffle to a third position when the steam generator is in standby mode, and acquire a second temperature value in the cooking cavity through a temperature detection device, wherein the third position is located between the first position and the second position; adjust the cooling fan to a first gear when the second temperature value is above a first preset temperature threshold; and adjust the cooling fan to a second gear when the second temperature value is below the first preset temperature threshold.

[0099] As described above, when the steam generator is in standby mode, the pressure relief requirement of the cooking chamber is less than that when the steam generator is running. In this case, adjusting the baffle to the third position prevents the pressure relief port from fully opening, helping to ensure the heating effect of the cooking equipment. At this time, adjusting the cooling fan speed according to the temperature in the cooking chamber ensures both heating and cooling efficiency of the cooking equipment.

[0100] In some embodiments, the controller 111 is further configured to: upon detecting a cooling command, adjust the baffle to a second position in response to the received cooling command, and adjust the cooling fan to a first setting.

[0101] As can be seen from the above, when a cooling command is detected, it indicates that the cooking equipment needs to be cooled down quickly. At this time, adjusting the baffle to the second position and adjusting the cooling fan to the first setting will fully open the pressure relief vent and adjust the cooling fan to the high-power setting, which will help ensure the heat dissipation effect of the cooking equipment.

[0102] It is understood that the structures illustrated in the embodiments of the present invention do not constitute a specific limitation on the cooking device. In other embodiments of this application, the cooking device may include more or fewer components than illustrated, or combine some components, or separate some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0103] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0104] This application provides a control method for a cooking device, which is applied to a controller, such as the controller 111 in the oven described above. Figure 10 As shown, taking an oven as an example of a cooking device, the control method provided in this application embodiment may include the following steps:

[0105] S101. When the steam generator is in operation, acquire the first pressure value in the cooking chamber, and acquire the steam flow rate value generated by the steam generator within a preset time.

[0106] In some embodiments, during the cooking process, while the steam generator is in operation, a first pressure value in the cooking chamber is acquired, and the steam flow rate value generated by the steam generator within a preset time period is acquired, so as to adjust the position of the baffle.

[0107] S102. Adjust the position of the baffle according to the first pressure value and the steam flow rate generated within the preset time.

[0108] In some embodiments, during the cooking process, the position of the baffle is adjusted according to the first pressure value and the steam flow rate generated within a preset time, so as to ensure the pressure relief effect of the cooking equipment and the heating effect of the cooking equipment.

[0109] See Figure 11 As shown, the above S102 can be specifically implemented as follows:

[0110] S201. If the first preset condition is met, adjust the baffle to the second position.

[0111] The first preset condition includes a first pressure value that is above a preset pressure threshold and / or a steam flow rate value that is above a preset steam quantity threshold within a preset time period.

[0112] It should be noted that the preset pressure threshold, preset duration, and preset steam quantity threshold can be preset by the cooking equipment at the factory or set by the user. This application does not impose any specific restrictions on this.

[0113] In some embodiments, during the cooking process, if the first pressure value in the cooking chamber is above a preset pressure threshold and / or the steam flow rate generated within a preset time period is above a preset steam quantity threshold, the baffle is adjusted to the second position to ensure the pressure relief effect of the cooking device.

[0114] For example, suppose the preset pressure threshold is 1.3 atmospheres, the preset duration is 10 minutes, and the preset steam volume threshold is 0.5 cubic meters. If the pressure of cooking device A is detected to be 1.4 atmospheres, and the steam volume generated within 10 minutes is 0.6 cubic meters, then the pressure inside the cooking cavity is determined to be greater than the preset pressure threshold, and the steam volume generated within the preset duration is greater than the preset steam volume threshold, thus satisfying the first preset condition. The baffle is then adjusted to the second position to fully open the pressure relief vent.

[0115] For example, suppose the preset pressure threshold is 1.3 atmospheres, the preset duration is 10 minutes, and the preset steam volume threshold is 0.5 cubic meters. If the pressure of cooking device A is detected to be 1.1 atmospheres, and the steam volume generated within 10 minutes is 0.7 cubic meters, then the pressure inside the cooking cavity is determined to be less than the preset pressure threshold, but the steam volume generated within the preset duration is greater than the preset steam volume threshold, thus satisfying the first preset condition. The baffle is then adjusted to the second position to fully open the pressure relief vent.

[0116] S202. If the first preset condition is not met, adjust the baffle to the third position.

[0117] The third position is located between the first and second positions.

[0118] For example, see Figure 12 As shown, the baffle is in the third position at this time. The third position can be located in the middle of the first and second positions, so that the pressure relief port is opened halfway.

[0119] In some embodiments, during the cooking process, if the first pressure value in the cooking chamber is below a preset pressure threshold and the steam flow rate generated within a preset time is below a preset steam quantity threshold, the baffle is adjusted to a third position to ensure the pressure relief effect of the cooking device.

[0120] For example, suppose the preset pressure threshold is 1.2 atmospheres, the preset duration is 5 minutes, and the preset steam volume threshold is 0.3 cubic meters. If the pressure of cooking device A is detected to be 1.1 atmospheres, and the steam volume generated within 5 minutes is 0.2 cubic meters, then the pressure inside the cooking cavity is determined to be less than the preset pressure threshold, and the steam volume generated within the preset duration is less than the preset steam volume threshold, thus failing to meet the first preset condition. Therefore, the baffle is adjusted to the third position to prevent the pressure relief port from fully opening.

[0121] based on Figure 11 The illustrated embodiment offers at least the following beneficial effects: When the first pressure value is above a preset pressure threshold and / or the flow rate generated within a preset time period is above a preset steam threshold, the pressure inside the cooking chamber is too high and / or there is too much steam. If the steam cannot be vented in time, condensation may occur as the gas in the cooking chamber diffuses into the cooking equipment. It should be understood that adjusting the baffle to the second position when the pressure inside the cooking chamber is too high and / or there is too much steam helps to ensure the pressure relief effect of the cooking equipment, thereby helping to extend the service life of the cooking equipment.

[0122] Furthermore, when the first pressure value is below a preset pressure threshold and the flow rate generated within a preset time is below a preset steam threshold, i.e., when the cooking chamber does not require rapid pressure relief or rapid exhaust, the baffle is adjusted to the third position. It should be understood that adjusting the baffle to the third position, with the pressure relief port not fully open, can prevent the heating effect of the cooking equipment from being affected by an excessively large pressure relief port, thereby helping to ensure the cooking effect of the cooking equipment.

[0123] S103. After adjusting the position of the baffle, obtain the first temperature value in the cooking cavity.

[0124] In some embodiments, during the cooking process, after adjusting the position of the baffle, in order to ensure the heat dissipation effect of the cooking equipment, a first temperature value in the cooking cavity is obtained so as to adjust the speed of the cooling fan.

[0125] S104. Adjust the speed of the cooling fan according to the first temperature value and the position of the baffle after adjustment.

[0126] It should be noted that the cooling fan has a first speed setting and a second speed setting. The power corresponding to the first speed setting is greater than that corresponding to the second speed setting. The first speed setting can be understood as the high-speed setting of the cooling fan, and the second speed setting can be understood as the low-speed setting of the cooling fan.

[0127] In some embodiments, during the cooking process, in order to ensure the heat dissipation effect of the cooking equipment, the speed of the cooling fan is adjusted according to the obtained first temperature value and the adjusted position of the baffle.

[0128] See Figure 13 As shown, the above S104 can be specifically implemented as follows:

[0129] S301. When the baffle is adjusted to the second position and the first temperature value is above the first preset temperature threshold, the cooling fan is adjusted to the first gear.

[0130] It should be noted that the first preset temperature threshold can be preset when the cooking device leaves the factory or preset by the user. This application does not impose any specific restrictions on this.

[0131] In some embodiments, during the cooking process, when the baffle is adjusted to the second position and the first temperature value is above the first preset temperature threshold, the cooling fan is adjusted to the first setting to facilitate heat dissipation from the cooking cavity.

[0132] For example, assuming the first temperature threshold is 150 degrees Celsius, the baffle is adjusted to the second position. The first temperature value inside the cooking cavity is obtained as 170 degrees Celsius. The first temperature value is greater than the first preset temperature threshold and the baffle is adjusted to the second position. At this time, the cooling fan is adjusted to the first setting to facilitate heat dissipation from the cooking cavity.

[0133] S302. When the baffle is adjusted to the second position and the first temperature value is below the second preset temperature threshold, the cooling fan is adjusted to the second gear.

[0134] The second preset temperature threshold is below the first preset temperature threshold.

[0135] It should be noted that when the baffle is adjusted to the second position and the first temperature value is between the first preset temperature threshold and the second preset temperature threshold, the cooling fan is controlled to maintain the current speed.

[0136] In some embodiments, during the cooking process, when the baffle is adjusted to the second position and the first temperature value is below the second preset temperature threshold, the cooling fan is adjusted to the second level to avoid excessive heat dissipation from the cooking cavity, which would affect the heating effect of the cooking device.

[0137] For example, assuming the second preset temperature threshold is 120 degrees Celsius, the baffle is adjusted to the second position. The first temperature value inside the cooking cavity is obtained as 100 degrees Celsius. At this time, the first temperature value is less than the first preset temperature threshold and the baffle is adjusted to the second position. The cooling fan is then adjusted to the second setting to avoid excessive heat dissipation from the cooking cavity, which would affect the heating effect of the cooking equipment.

[0138] based on Figure 13 The illustrated embodiment offers at least the following advantages: When the baffle is adjusted to the second position and the first temperature value is above the first preset temperature threshold, it indicates that the pressure relief vent is fully open and the temperature in the cooking cavity is high. Using the first setting of the cooling fan at this time helps ensure the heat dissipation effect of the cooking equipment. When the baffle is adjusted to the second position and the first temperature value is below the second preset temperature threshold, it indicates that the pressure relief vent is fully open but the temperature in the cooking cavity is normal. Using the second setting of the cooling fan at this time helps ensure the heating effect of the cooking equipment.

[0139] See Figure 14 As shown, the above S104 can also be specifically implemented as follows:

[0140] S401. When the gear is adjusted to the third position and the first temperature value is above the first preset temperature threshold, adjust the cooling fan to the first gear.

[0141] In some embodiments, during the cooking process, when the setting is adjusted to the third position and the first temperature value is above the first preset temperature threshold, the cooling fan is adjusted to the first setting to facilitate heat dissipation from the cooking cavity.

[0142] For example, assuming the first preset temperature threshold is 150 degrees Celsius, the baffle is adjusted to the third position. The temperature inside the cooking cavity is obtained as 160 degrees Celsius, that is, the temperature inside the cooking cavity is greater than the first preset temperature threshold and the baffle is adjusted to the third position. At this time, the cooling fan is adjusted to the first setting.

[0143] S402. When the gear is adjusted to the third position and the first temperature value is below the third preset temperature threshold, adjust the cooling fan to the second gear.

[0144] The third preset temperature threshold is between the first preset temperature threshold and the second preset temperature threshold; for example, the first preset temperature threshold is 150 degrees Celsius, the second preset temperature threshold is 120 degrees Celsius, and the third preset temperature threshold is 130 degrees Celsius.

[0145] It should be noted that when the baffle is adjusted to the third position and the first temperature value is between the first preset temperature threshold and the second preset temperature threshold, the cooling fan is controlled to maintain the current speed.

[0146] In some embodiments, during the cooking process, when the baffle is adjusted to the third position and the first temperature value is below the second preset temperature threshold, the cooling fan is adjusted to the second level to avoid excessive heat dissipation from the cooking cavity, which would affect the heating effect of the cooking device.

[0147] For example, assuming the preset temperature threshold is 130 degrees Celsius and the baffle is adjusted to the third position, the temperature inside the cooking cavity is found to be 120 degrees Celsius. That is, the temperature inside the cooking cavity is less than the third preset temperature threshold and the baffle is adjusted to the third position. At this time, the cooling fan is adjusted to the second setting.

[0148] based on Figure 14The illustrated embodiment offers at least the following advantages: When the baffle is adjusted to the second position and the first temperature value is above the first preset temperature threshold, the pressure relief vent is not fully open and the temperature in the cooking cavity is too high. Using the first setting of the cooling fan in this situation helps ensure the heat dissipation effect of the cooking equipment. When the baffle is adjusted to the second position and the first temperature value is below the third preset temperature threshold, it indicates that the pressure relief vent is not fully open, but the temperature in the cooking cavity is normal. Using the second setting of the cooling fan in this situation helps ensure the heating effect of the cooking equipment.

[0149] Based on the above, see [link / reference] Figure 15 As shown, after adjusting the position of the baffle and obtaining the first temperature value in the cooking cavity, the above-mentioned S104 can be specifically implemented as S301, S302, S401 and S402.

[0150] based on Figure 10 The illustrated embodiment offers at least the following advantages: When the steam generator is running, the pressure in the cooking chamber may be too high. In this case, the position of the baffle is adjusted based on the obtained pressure value in the cooking chamber and the steam flow rate generated by the steam generator within a preset time. It should be understood that adjusting the baffle position based on the first pressure value and the amount of steam generated within the preset time helps ensure the pressure relief effect of the cooking equipment when the cooking chamber needs to be depressurized, thereby preventing gas in the cooking chamber from escaping from the weak points in the seal between the cooking chamber and the door, and thus outside the cooking chamber; it also helps prevent the heating effect of the cooking equipment from being affected by an excessively large opening of the pressure relief port when the cooking chamber does not need to be depressurized.

[0151] Furthermore, adjusting the fan speed based on the adjusted position of the baffle and the temperature in the cooking cavity helps ensure the heat dissipation effect of the cooking equipment.

[0152] In summary, the technical solution provided in this application helps ensure the pressure relief and heat dissipation effect of the cooking equipment, thereby helping to avoid excessively high temperatures in the cooking cavity due to poor heat dissipation. It also helps to prevent gas from the cooking cavity from spreading into the interior of the cooking equipment and forming condensation, thus ensuring the service life of the cooking equipment. Simultaneously, the technical solution provided in this application also ensures the heating effect of the cooking equipment, achieving the goal of extending the service life of the cooking equipment while guaranteeing its cooking efficiency.

[0153] See Figure 16 As shown, the control method for the cooking equipment provided in this application may further include:

[0154] S501. With the steam generator in standby mode, adjust the baffle to the third position and obtain the second temperature value in the cooking cavity.

[0155] In some embodiments, during the cooking process, while the steam generator is in standby mode, the baffle is adjusted to a third position, and a second temperature value in the cooking chamber is obtained to adjust the heat dissipation effect of the cooking device.

[0156] It should be noted that when the steam generator is in standby mode, there is no need to release pressure or vent the cooking chamber. Therefore, the baffle is adjusted to the third position so that the pressure release vent is not fully open. This partially open position will not affect the heat dissipation of the cooking chamber or the heating effect of the cooking equipment.

[0157] S502. When the second temperature value is above the first preset temperature threshold, adjust the cooling fan to the first setting.

[0158] In some embodiments, during the cooking process, when the steam generator is in standby mode and the second temperature value is above the first preset temperature threshold, the cooling fan is adjusted to the first setting to ensure the heat dissipation effect of the cooking equipment.

[0159] For example, assuming the steam generator is in standby mode, the first preset temperature threshold is 150 degrees Celsius. During cooking, if the second temperature value obtained in the cooking cavity is 160 degrees Celsius, and this second temperature value is above the first preset temperature threshold, the cooling fan is adjusted to the first setting.

[0160] based on Figure 16 The illustrated embodiment offers at least the following advantages: When the steam generator is in standby mode, the pressure relief demand of the cooking chamber is less than that when the steam generator is in operation. Adjusting the baffle to the third position at this time prevents the pressure relief port from fully opening, thus helping to ensure the heating effect of the cooking equipment. Furthermore, when the second temperature value is above the first preset temperature threshold, adjusting the cooling fan to the first setting helps to ensure both heating and cooling effects of the cooking equipment.

[0161] See Figure 17 As shown, the control method for the cooking equipment provided in this application may further include, after S501 above:

[0162] S503. If the second temperature value is below the first preset temperature threshold, adjust the cooling fan to the second setting.

[0163] In some embodiments, during the cooking process, when the steam generator is in standby mode and the second temperature value is below the first preset temperature threshold, the cooling fan is adjusted to the second setting to avoid excessive heat dissipation from the cooking cavity, which would affect the heating effect of the cooking equipment.

[0164] For example, assuming the steam generator is in standby mode, the first preset temperature threshold is 150 degrees Celsius. During cooking, if the second temperature value in the cooking cavity is 120 degrees Celsius, which is below the first preset temperature threshold, the cooling fan is adjusted to the second setting.

[0165] based on Figure 17 The illustrated embodiment offers at least the following advantages: When the steam generator is in standby mode, the pressure relief demand of the cooking chamber is less than that when the steam generator is in operation. Adjusting the baffle to the third position at this time prevents the pressure relief port from fully opening, thus helping to ensure the heating effect of the cooking equipment. Furthermore, when the second temperature value is below the first preset temperature threshold, adjusting the cooling fan to the second setting helps to ensure both the cooling and heating effects of the cooking equipment.

[0166] See Figure 18 As shown, the control method for the cooking equipment provided in this application may further include:

[0167] S601. During the cooking process, detect the control commands sent by the control panel.

[0168] In some embodiments, during the cooking process, control commands sent by the control panel are detected so as to respond to user commands in a timely manner.

[0169] S602. Upon detecting a cooling command, in response to the received cooling command, the baffle is adjusted to the second position, and the cooling fan is adjusted to the first position.

[0170] In some embodiments, during cooking, upon detecting a cooling command, in response to the received cooling command, the baffle is adjusted to a second position and the cooling fan is adjusted to a first setting so that the cooking device can exert its maximum heat dissipation capacity.

[0171] based on Figure 18 The embodiment shown has at least the following beneficial effects: when a cooling command is detected, it indicates that the cooking equipment needs to be cooled down quickly. At this time, the baffle is adjusted to the second position and the cooling fan is adjusted to the first level, so that the pressure relief port is fully opened and the cooling fan is adjusted to the high speed level, which helps to ensure the heat dissipation effect of the cooking equipment.
