The present application does not limit the type of the spray component.

[0052] In some embodiments, the reading device 5 may be a two-dimensional code reading device, a barcode reading device, an NFC label reading device, or an IC chip reading device, which is used to read the dish identification to obtain the recipe information or to obtain the recipe information online, and transmit the recipe information to the control unit. This application does not limit the reading method of the reading device.

[0053] In some embodiments, the display unit 6 is used to display the working status and operation instructions of the cooking device.

[0054] Figure 2 The hardware configuration block diagram of a steam generator provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the steam generator 3 includes: a water inlet 31 , a heating device 32 , a steam outlet 33 and an exhaust port 34 .

[0055] In some embodiments, the water inlet 31 is used to supply water to the steam generator 3 .

[0056] In some embodiments, the heating device 32 is used to heat the water in the steam generator 3 into water vapor.

[0057] In some embodiments, the steam outlet 33 is used to deliver steam into the cooking cavity.

[0058] In some embodiments, the exhaust port 34 is used to exhaust excess gas in the steam generator 3 to avoid the risk of overload or explosion due to excess gas.

[0059] Figure 3 This is a schematic diagram of the water inlet system of a water box provided in an embodiment of the present application. Figure 3 As shown, the water inlet system includes: a water inlet pipeline, a water inlet quick-connect interface and a water inlet valve.

[0060] In some embodiments, clean water flows to the water box through a water inlet pipe in the cooking device 10 .

[0061] In some embodiments, a water inlet quick-connect interface is provided at the water inlet end of the water inlet pipeline for connecting the water inlet pipeline and the water inlet valve.

[0062] In some embodiments, a water inlet valve is disposed on the water box to allow water to flow into the water box.

[0063] Figure 4 A schematic diagram of a sensor system of a water box provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the sensor system includes a water level sensor and a position sensor.

[0064] In some embodiments, a water level sensor is used to detect the water level in the water box.

[0065] It should be noted that the water level sensor may be a float switch or other sensor for detecting the water level in the water box, and this application does not limit this.

[0066] In some embodiments, a position sensor is used to detect whether the water box is placed in place.

[0067] Figure 5 A schematic diagram of a water circulation system of a water box provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the water circulation system also includes a drain valve, a three-way valve and an external drain port.

[0068] In some embodiments, a drain valve is disposed in the cooking cavity 1 for draining water out of the cooking cavity.

[0069] In some embodiments, a three-way valve is connected to the drain valve and the cleaning module to control the flow direction of water in the cooking cavity.

[0070] In some embodiments of the present application, the drain valve is a three-way valve, one way of which can drain water out of the cooking chamber, and the other way is connected to the cleaning module to circulate the clean water for cleaning.

[0071] In some embodiments, an external drain port is used to drain the water in the inner tank water collector into a sewer.

[0072] For example, when the water in the cooking chamber is steam condensate, the steam condensate can be transported to the cleaning module through a three-way valve and used as clean water, thereby realizing the recycling of water resources and reducing waste.

[0073] For another example, when the water in the cooking cavity is clean waste water, the clean waste water in the inner tank water collector can be transported to the external drain port through the three-way valve, thereby discharging the clean waste water from the cooking cavity to the sewer.

[0074] In the embodiment shown in the present application, the controller 1000 refers to a device that can generate an operation control signal according to the instruction operation code and the timing signal to instruct the cooking device 10 to execute the control instruction. Exemplarily, the controller 1000 can be a central processing unit (CPU), a general-purpose processor network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD) or any combination thereof. The controller 1000 can also be other devices with processing functions, such as circuits, devices or software modules, and the embodiments of the present application do not impose any restrictions on this.

[0075] In addition, the controller 1000 can be used to control various components inside the cooking device 10 so that each component operates to achieve various predetermined functions of the cooking device 10.

[0076] In some embodiments, the controller 1000 is configured to: obtain the operating mode of the cooking device; determine the target drainage condition corresponding to the operating mode according to the operating mode; the target drainage condition includes at least one of the following conditions: the drainage volume of the water box is greater than or equal to a preset drainage volume threshold, and the operating mode is completed; when the cooking device meets the target drainage condition, the drain valve is controlled to open to drain the water in the cooking cavity.

[0077] In some embodiments, the controller 1000 is further configured to: detect the water level in the water box through a water level sensor; and control the cooking device to operate in the above-mentioned operating mode when the water level reaches a preset water level.

[0078] In some embodiments, the controller 1000 is also configured to: obtain the number of unclean operation times and the duration of unclean operation of the steam generator; when the number of unclean operation times of the steam generator is greater than or equal to the first number threshold, or the duration of unclean operation is greater than or equal to the preset duration, control the cooking device to run the steam generator cleaning mode.

[0079] In some embodiments, the controller 1000 is further configured to: obtain the number of unclean operation times of the cooking device; and control the cooking device to run a whole-machine cleaning mode when the number of unclean operation times of the cooking device is greater than or equal to a second number threshold.

[0080] Figure 6 FIG. 1 is a hardware configuration block diagram of another cooking device provided by the present application according to an exemplary embodiment. Figure 6 As shown, the cooking device 10 may further include the following two items: a communicator 1002 and a memory 1003 .

[0081] In some embodiments, the communicator 1002 is used to establish a communication connection with other network entities, such as establishing a communication connection with a terminal device. The communicator 1002 may include a radio frequency (RF) module, a cellular module, a wireless fidelity (WIFI) module, and a GPS module. Taking the RF module as an example, the RF module can be used for receiving and sending signals, in particular, sending the received information to the controller 1000 for processing; in addition, sending the signal generated by the controller 1000. 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.

[0082] In some embodiments, the memory 1003 can be used to store software programs and data. The controller 1000 executes various functions and data processing of the cooking device 10 by running the software programs or data stored in the memory 1003. The memory 1003 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage device. The memory 1003 stores an operating system that enables the cooking device 10 to run. In the present application, the memory 1003 can store an operating system and various application programs, and can also store code for executing the control method of the cooking device 10 provided in the embodiment of the present application.

[0083] Those skilled in the art will understand that Figure 6The hardware structure shown in the figure does not constitute a limitation on the cooking device. The cooking device may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0084] Figure 7 A flowchart of a method for controlling a cooking device provided in an embodiment of the present application.

[0085] like Figure 7 As shown, the method comprises the following steps:

[0086] S101. A controller obtains an operating mode of a cooking device.

[0087] The operation mode of the cooking device may include a steam cooking mode, a steam generator cleaning mode, a whole machine cleaning mode or other possible operation modes.

[0088] In some embodiments, when the cooking device is turned on, the controller first controls the drain valve to open to drain the water in the cooking cavity to prevent the waste water in the cooking cavity from affecting the cooking effect.

[0089] Furthermore, after the water in the cooking cavity is drained, the controller controls the cooking device to operate normally.

[0090] In some embodiments, before the cooking device normally operates in the current operation mode, the amount of water in the water box needs to be determined first. When the amount of water in the water box meets the water amount requirement of the operation mode, the cooking device is controlled to normally operate in the operation mode.

[0091] Alternatively, when the amount of water in the water box does not meet the water requirement of the operation mode, the water inlet valve may be controlled to control the water inlet to the water box, or a water shortage reminder may be issued to the user.

[0092] For example, the cooking device may broadcast a voice message such as "Please add water to the water box", or the cooking device may display a similar text message such as "Please add water to the water box" on a reading device, or may flash a water adding indicator light to remind the user to add water manually.

[0093] Figure 8 A flow chart of another control method for a cooking device provided in an embodiment of the present application, which is used to control the opening of a water inlet valve. Figure 8 As shown, the method includes:

[0094] S11. The controller obtains the water level in the water box.

[0095] Optionally, the controller may detect the water level in the water box via a water level sensor.

[0096] In some embodiments, after the water in the water box and the cooking cavity is drained, the controller needs to determine whether the cooking device can start running in the current operation mode through the water level in the water box detected by the water level sensor.

[0097] S12. When the water level reaches a preset water level, control the cooking device to run the above operation mode.

[0098] The preset water level may be preset by the cooking device manufacturer and stored in the memory, and different manufacturers may set different preset water levels. Alternatively, the preset water level may be determined by the controller based on historical operation data of the cooking device. Alternatively, the preset water level may be set by the user based on usage habits. This application does not limit this.

[0099] In some embodiments, the preset water levels corresponding to different operating modes may be different. When the controller determines the operating mode currently to be operated, the controller may obtain the recorded preset water level corresponding to the operating mode. Alternatively, the preset water levels corresponding to different operating modes may be the same.

[0100] Exemplarily, if the operation mode of the cooking device is the steam cooking mode, when the water level reaches a preset water level, the controller controls the water inlet valve to close, and controls the cooking device to operate in the steam cooking mode.

[0101] Fig. 9 A flow chart of another cooking device control method provided in an embodiment of the present application, such as Fig. 9 As shown, the method includes:

[0102] S13: When the water level does not reach the preset water level, the controller controls the water inlet valve to open, or sends a reminder to the user to add water.

[0103] Exemplarily, when the water level does not reach the preset water level, the controller controls the water inlet valve to open to let water into the water box until the water level in the water box reaches the preset water level.

[0104] Alternatively, when the water level does not reach the preset water level, the controller can send a water-adding reminder to the user through the reading device, reminding the user to manually add water until the water level in the water box reaches the preset water level.

[0105] In some embodiments, after the water in the water box and the cooking cavity is drained, if the operation mode selected by the user is the steam cooking mode, when the water level reaches a preset water level, the controller controls the cooking device to operate the steam cooking mode.

[0106] Furthermore, when the cooking device is running in the steam cooking mode, the controller continuously detects whether the water level in the water box meets the cooking requirements through the water level sensor. When the water level in the water box does not meet the cooking requirements, the controller controls the water inlet valve to open to fill water into the water box to a preset water level.

[0107] Fig.10 A flow chart of another cooking device control method provided in an embodiment of the present application is used to determine the operation mode of the cooking device. Fig.10 As shown, the method includes:

[0108] S21. The controller obtains the number of uncleaned operation times and the uncleaned operation duration of the steam generator.

[0109] Among them, the steam generator is used to provide steam into the cooking cavity to steam the cooking ingredients. The steam generator can be a direct injection type, a boiling water type or other types of generators, which is not limited in this application.

[0110] The number of uncleaned runs of the steam generator is the number of runs of the steam generator since the last run of the steam generator cleaning mode. The uncleaned run time is the total run time of the steam generator since the last run of the steam generator cleaning mode.

[0111] S22: When the number of unclean operation times of the steam generator is greater than or equal to the first number threshold, or the unclean operation time is greater than or equal to the preset time, the controller controls the cooking device to operate the steam generator cleaning mode.

[0112] It should be noted that when the steam generator is not run cleaned too many times or for too long, scale and other substances may appear inside the steam water path of the steam generator, affecting the working efficiency of the steam generator. At this time, the controller needs to control the cooking equipment to run the steam generator cleaning mode to clean these substances so that the steam generator can run better.

[0113] Among them, the first number threshold and preset time are preset by the cooking equipment manufacturer and stored in the memory. The first number threshold and preset time set by different manufacturers may be different, and this application does not limit this.

[0114] Optionally, the first count threshold may be N times, and the preset duration may be M minutes.

[0115] Exemplarily, when the number of unclean operation times n of the steam generator is greater than or equal to the first number threshold, or the unclean operation duration m is greater than or equal to the preset duration, that is, when n≥N or m≥M, the controller controls the cooking device to operate the steam generator cleaning mode.

[0116] In some embodiments, when the controller controls the cooking device to run the steam generator cleaning mode and the water level in the water box reaches a preset water level, the controller needs to use a position sensor to determine whether the water box is placed in place. If the water box is not placed in place, the controller needs to prompt the user to place the water box in place through a reading device and place the cleaning supplies into the cleaning module.

[0117] Furthermore, the controller starts the cleaning module and the circulating water circuit of the steam generator to clean the scale and other substances inside the steam water circuit. During the cleaning period, the water level sensor continuously detects whether the water level in the water box meets the cleaning requirements. If the water level in the water box does not meet the cleaning requirements, the controller controls the water inlet valve to open to let water into the water box.

[0118] In some embodiments, when the number of unclean operation times of the steam generator is less than the first number threshold and the unclean operation duration is less than a preset duration, the possibility of scale forming in the steam water path of the steam generator is small and there is no need to clean the steam generator. The controller controls the cooking device to continue running the steam cooking mode.

[0119] Exemplarily, when n<N and m<M, the controller controls the cooking device to continue to operate the steam cooking mode.

[0120] Fig.11 A flow chart of another cooking device control method provided in an embodiment of the present application is used to determine the operation mode of the cooking device. Fig.11 As shown, the method includes:

[0121] S31. The controller obtains the number of unclean operation times of the cooking device.

[0122] The number of uncleaned operations of the cooking device is the total number of times the cooking device has run the steam cooking mode since the last time the cooking device ran the whole machine cleaning mode.

[0123] S32: When the number of times the cooking device has not been cleaned is greater than or equal to a second threshold value, the controller controls the cooking device to run a whole-machine cleaning mode.

[0124] It should be understood that when the cooking equipment is not run cleanly too many times, scale, food residues and other substances may appear inside the cooking cavity, which may affect the hygiene and safety of the ingredients cooked next time. At this time, the controller needs to control the cooking equipment to run the whole-machine cleaning mode to clean these substances to make cooking more hygienic and safer.

[0125] It should be noted that the second number threshold is preset by the cooking equipment manufacturer and stored in the memory. The second number threshold set by different manufacturers may be different, and this application does not limit this.

[0126] Optionally, the second number threshold may be G times.

[0127] Exemplarily, when the number of unclean operation times g of the cooking device is greater than or equal to the second number threshold G, that is, when g≥G, the controller controls the cooking device to run the whole-machine cleaning mode.

[0128] In some embodiments, when the controller controls the cooking equipment to run the whole-machine cleaning mode and the water level in the water box reaches a preset water level, the controller needs to use a position sensor to determine whether the water box is placed in place. If the water box is not placed in place, the controller needs to prompt the user to put the water box in place through a reading device and place the cleaning supplies into the cleaning module.

[0129] Furthermore, the controller controls the cleaning module to circulate and flush the solution mixed with cleaning products in the cooking cavity for several times. When the flushing times reach the cycle times, the controller controls the drain valve to open to drain the water in the cooking cavity, and at the same time opens the water inlet valve to fill water into the water box to a preset water level.

[0130] Furthermore, after the water in the cooking cavity is drained and the water level in the water box reaches a preset water level, the controller controls the cleaning module again to circulate the solution mixed with cleaning supplies in the cooking cavity for several times. The above steps are repeated to deeply clean the cooking cavity.

[0131] It should be noted that the above-mentioned cleaning items may be cleaning powder, cleaning blocks, citric acid or other possible cleaning items, and the present application does not limit this.

[0132] S102: The controller determines a target drainage condition corresponding to the operation mode according to the operation mode.

[0133] The target drainage condition includes at least one of the following conditions: the drainage volume of the water box is greater than or equal to a preset drainage volume threshold, and the operation mode is completed.

[0134] In some embodiments, when the operating mode is the steam cooking mode or the steam generator cleaning mode, the target drainage condition is that the drainage volume of the water box is greater than or equal to a preset drainage volume threshold, and / or the steam cooking mode or the steam generator cleaning mode is completed.

[0135] In some embodiments, when the operation mode is the whole machine cleaning mode, the target drainage condition is that the whole machine cleaning mode is completed.

[0136] Among them, the preset drainage volume threshold is preset by the cooking equipment manufacturer and stored in the memory. The preset drainage volume threshold set by different manufacturers may be different, and this application does not limit this.

[0137] S103: When the cooking device meets the target drainage condition, the controller controls the drainage valve to open.

[0138] In some embodiments, when the operation mode of the cooking device is the steam cooking mode, the controller needs to determine whether to control the drain valve to open according to the drainage volume of the water box and a preset drainage volume threshold.

[0139] In some embodiments, the amount of water discharged from the water box is related to the amount of water consumed by the cooking device during operation and / or the amount of water generated or absorbed by the cooking ingredients themselves.

[0140] It should be understood that since the cooking ingredients may produce some water during the cooking process (for example, scallops will produce juice during steaming and baking), and the cooking equipment may also consume a certain amount of water during operation, different recipes absorb different amounts of water. Therefore, the drainage volume of the water box needs to be determined in combination with the water consumption of the cooking equipment during operation and / or the water produced or absorbed by the cooking ingredients themselves.

[0141] Furthermore, since the cooking ingredients may generate some water during the cooking process, resulting in the drainage volume being greater than the water output in the water box, a first correction coefficient is set to correct the water output.

[0142] At the same time, since a certain amount of water may be consumed during the operation of the cooking device, resulting in the drainage volume being less than the water output in the water box, a second correction coefficient is set to correct the water output.

[0143] Among them, the first correction coefficient and the second correction coefficient are preset by the cooking equipment manufacturer and stored in the memory. The first correction coefficient and the second correction coefficient set by different manufacturers may be different, and this application does not limit this.

[0144] Optionally, the first correction coefficient may be α, and the second correction coefficient may be β.

[0145] Exemplarily, when the operation mode of the cooking device is the steam cooking mode, the calculation method of the drainage volume of the water box is as shown in formula (1):

[0146] M 1 =α*β*m 1 Formula (1)

[0147] Among them, M 1 is the displacement, m 1 is the water output of the water box.

[0148] Furthermore, when the operation mode of the cooking device is the steam cooking mode, the water discharge volume M 1 Greater than or equal to the preset discharge threshold M 2 , that is, in M 1 ≥M 2In the case where the cooking device meets the target drainage condition, the controller controls the drainage valve to open to drain the water in the cooking cavity.

[0149] In some embodiments, when the steam cooking mode ends and the cooking device meets a target drainage condition, the controller controls the drainage valve to open to drain the water in the cooking cavity.

[0150] In some embodiments, when the operation mode of the cooking device is the steam generator cleaning mode, the controller needs to determine whether to control the drain valve to open according to the drainage volume of the water box and a preset drainage volume threshold.

[0151] Exemplarily, when the operating mode of the cooking device is the steam generator cleaning mode, when the drainage volume of the water box is greater than or equal to a preset drainage volume threshold, the cooking device meets the target drainage condition, and the controller controls the drain valve to open to drain the water in the cooking cavity.

[0152] In some embodiments, at the end of the steam generator cleaning mode operation, the cooking device meets the target drainage condition, and the controller controls the drain valve to open.

[0153] In some embodiments, when the operation mode of the cooking device is the whole machine cleaning mode, the controller detects the water level in the water box through a water level detector to calculate the amount of water entering the water box each time. When the amount of water entering one time is less than or equal to a preset drainage threshold, the whole machine cleaning mode is completed, the cooking device meets the target drainage conditions, and the controller controls the drain valve to open to drain the water in the cooking cavity.

[0195] In the related art, a waste water box is often provided outside the inner pot of the cooking device, and a water level sensor is provided in the waste water box. When the water level sensor detects that the water level in the waste water box reaches a preset threshold, it reminds to drain or automatically drains the waste water in the waste water box. However, this drainage method cannot accurately match multiple operating modes. For example, this drainage method is not compatible with the cleaning mode, and the drainage time is unreasonable or untimely, which leads to odor or sanitary safety problems in the waste water box. In addition, the waste water box is not easy to clean, which affects the user experience.

[0196] The technical solution of the present application realizes matching different drainage conditions under different operation modes through the target operation mode of the equipment and the corresponding target drainage conditions, thereby completing the intelligent control of the drainage valve, and also facilitating the timely cleaning of wastewater generated during the operation of the cooking equipment, thereby ensuring the hygienic safety of cooking. In addition, the drainage condition in the present application uses the drainage volume of the water box to determine whether to drain. On the one hand, it is more suitable for the structural design of the wastewater box with a water level sensor in the cooking equipment without the need for an additional wastewater box. On the other hand, the physical quantity used is easy to measure and obtain, making the drainage process simple and easy to implement.
