[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0041] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, when describing a pipeline, the "connected" and "connection" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0043] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0044] Figure 1 The schematic diagram of the structure of a cooking device 10 provided in an embodiment of the present application, the cooking device 10 may be a steamer, an oven, a steamer-bake-in-one box, or a microwave oven. Figure 1 As shown, the cooking device 10 includes: a box body 101, a cooking cavity 102, a door body 103, a microwave transmitter 104 and a controller 105.

[0045] The box body 101 forms a cooking cavity 102 with an opening, and the cooking cavity 102 is a space for cooking food.

[0046] The door body 103 is installed at one end of the cabinet 101 and can open or close the opening of the cooking cavity 102 .

[0047] In some embodiments, the door body 103 further includes a door handle (not shown in the figure), which is used to assist the user in controlling the door body 103 to open or close the opening of the cooking cavity 102 .

[0048] In some embodiments, the door body 103 can be composed of a metal plate and a metal mesh, which can effectively isolate microwaves. The metal plate is not light-transmissive, but the metal mesh is light-transmissive. When the door body 103 is closed, the user can observe the situation inside the cooking cavity 102 through the metal mesh, and there will be no safety hazards.

[0049] The microwave transmitter 104 is used to output microwaves. It can be understood that the microwave transmitter 104 is an instrument that uses frequency synthesis technology to generate the required frequency or waveform signal. The microwave transmitter 104 outputs microwaves that can drive the polar molecules of food residues such as grease, water stains, starch and protein attached to the inside of the cooking cavity 102 to vibrate and rub, and then the temperature rises sharply to cause decomposition and carbonization.

[0050] In some embodiments, the microwave transmitter 104 can be divided into two types: feedback type and negative resistance type in terms of circuit structure. The feedback type microwave transmitter 104 is mainly used in low-frequency circuit systems, while the negative resistance type microwave transmitter 104 is mainly used in high-frequency circuit systems.

[0051] The controller 105 is connected to the microwave transmitter 104, and the controller 105 is configured to: receive a control instruction for cleaning the cooking cavity 102; and in response to the control instruction, control the microwave transmitter 104 to operate at a preset power until the operating time of the microwave transmitter 104 reaches the preset operating time.

[0052] In some embodiments, Figure 2 As shown, the microwave transmitter 104 may include a first magnetron 1041, a second magnetron 1042 and a booster ( Figure 2 not shown).

[0053] The first magnetron 1041 and the second magnetron 1042 are respectively connected to the controller 105 for outputting microwaves.

[0054] The booster is used to provide operating voltage for the first magnetron 1041 and the second magnetron 1042 .

[0055] although Figure 1 and Figure 2 Although not shown, the cooking device 10 may further include a memory 106, which is connected to the controller 105. The controller 105 executes various programs of the cooking device 10 by running or executing programs stored in the memory 106 and calling data stored in the memory 106. In some embodiments, the controller 105 may include one or more processing units.

[0056] In some embodiments, the controller 105 refers to a device that can generate an operation control signal according to an instruction opcode and a timing signal. Exemplarily, the controller 105 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 105 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.

[0057] In some embodiments, the memory 106 is used to store historical cooking data of the cooking device 10 , where the historical cooking data includes cooking time of meat recipes and cooking time of non-meat recipes.

[0058] In some embodiments, the memory 106 mainly includes a program storage area and a data storage area, wherein the program storage area can store an operating system and an application required for at least one function (such as a voice prompt function, an information display function, etc.); the data storage area can store data created when using the cooking device 10. In addition, the memory 106 can include a high-speed random access memory and can also include a non-volatile memory, such as a disk storage device, a flash memory device or other volatile solid-state storage devices.

[0059] Figure 3 FIG. 1 is a hardware configuration block diagram of a cooking device 10 according to an exemplary embodiment of the present application. Figure 3 As shown, the cooking device 10 may further include one or more of the following: a display 107 and a voice prompt device 108 .

[0060] In some embodiments, the display 107 is connected to the controller 105, and the display 107 can be a liquid crystal display or an organic light-emitting diode (OLED) display. The specific type, size, and resolution of the display 107 are not limited. The display 107 can be used to display the control panel of the cooking device. The cooking device can feedback the current working status of the cooking device through the display 107, such as the running time and working power.

[0061] In some embodiments, the voice prompt device 108 is connected to the controller 105, and can be used to issue a first voice prompt to remind the user to close the door 103 in time when the door 103 is open. The content of the first voice prompt can be pre-defined when the cooking device leaves the factory. For example, the content of the first voice prompt can be: "Please close the door in time". The voice prompt device 108 can also be used to issue a second voice prompt to remind the user that the microwave cleaning process has ended after the microwave transmitter 104 stops working. The content of the second voice prompt can be pre-defined when the cooking device leaves the factory. For example, the content of the second voice prompt can be: "Microwave cleaning is completed, please use a rag to clean up the carbonized products of food residues in time."

[0062] In some embodiments, the controller 105 is configured to: receive a control instruction for cleaning the cooking cavity 102; and in response to the control instruction, control the microwave transmitter 104 to operate at a preset power until the operating time of the microwave transmitter 104 reaches a preset operating time.

[0063] It should be understood that the operation of the microwave transmitter 104 can evaporate and carbonize the food residues inside the cooking cavity 102 of the cooking device 10. The user can easily clean the carbonized products of the food residues with a rag, and the cooking cavity 102 of the cooking device 10 can be cleaned without water resources, thereby improving the intelligence level of the cooking device 10 and saving water resources.

[0064] It is understood that the structure illustrated in the embodiment of the present invention does not constitute a specific limitation on the dishwasher. In other embodiments of the present application, the smart cooker and the smart stove may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0065] The embodiments provided in this application are described in detail below in conjunction with the accompanying drawings.

[0066] Figure 4 A flow chart of a control method for a cooking device provided in an embodiment of the present application, that is, a flow chart of a control method for cleaning a cooking cavity of a cooking device, the method is applied to a controller of the cooking device, and the method comprises the following steps:

[0067] S101, receiving a control instruction for cleaning a cooking cavity.

[0068] It can be understood that when the user needs to clean the cooking device, the user can send a control instruction to the controller of the cooking device by operating the control panel. The control instruction is used to instruct the cleaning of the cooking cavity. For example, a cleaning mode button is provided on the control panel of the cooking device. When the user presses the button, the control instruction for instructing the cleaning of the cooking cavity is sent to the controller of the cooking device. The controller receives the control instruction and executes the content indicated by the control instruction.

[0069] S102, in response to the control instruction, controlling the microwave transmitter to operate at a preset power until the operating time of the microwave transmitter reaches the preset operating time.

[0070] The preset working time is determined according to historical cooking data of the cooking device, and the historical cooking data includes the cooking time of meat recipes and the cooking time of non-meat recipes.

[0071] It is understandable that the longer the historical cooking time of the cooking equipment, the more food residues and other dirt inside the cooking cavity tend to be. Compared with non-meat recipes, meat recipes have a higher fat content. During the cooking process of meat recipes, oil stains are more likely to adhere to the inside of the cooking cavity, making the degree of dirt inside the cooking cavity after cooking meat recipes higher than after cooking non-meat recipes. Therefore, the microwave cleaning time, that is, the preset working time of the microwave transmitter, is determined according to the cooking time of the meat recipes and the cooking time of the non-meat recipes respectively, so that the preset working time of the microwave transmitter matches the degree of dirt inside the cooking cavity, so as to avoid the dirt inside the cooking cavity being completely decomposed and carbonized while the microwave transmitter is still working, causing energy waste. At the same time, it can also avoid the unreasonable preset working time of the microwave transmitter resulting in the dirt inside the cooking cavity not being completely decomposed and carbonized, which in turn leads to unsatisfactory cleaning effect and affects user experience.

[0072] In some embodiments, the preset working time and the cooking time of a meat recipe satisfy a monotonically increasing relationship, and the preset working time and the cooking time of a non-meat recipe also satisfy a monotonically increasing relationship.

[0073] The preset working time, the cooking time of meat recipes and the cooking time of non-meat recipes satisfy the following formula (1):

[0074] w=(3*a+b) / 1800+(3*a+b)*0.0135*n / (1800*(3*a+b+0.001)) formula (1)

[0075] Among them, w is the preset working time, a is the cooking time of meat recipes, b is the cooking time of non-meat recipes, and n is the cumulative cooking time since the cooking equipment was last cleaned. Among them, the unit of the preset working time is hours, and the unit of the cooking time of meat recipes, the cooking time of non-meat recipes and the cumulative cooking time is minutes.

[0076] In some embodiments, the preset working time can also be customized by the user when the cooking device needs to perform microwave cleaning. The preset working time can also be dynamically adjusted by the cooking device according to the degree of dirtiness inside the cooking cavity during the microwave cleaning process.

[0077] In some embodiments, the preset power is determined according to historical cooking data of the cooking device, where the historical cooking data includes cooking time of meat recipes and cooking time of non-meat recipes.

[0078] It is understandable that the longer the historical cooking time of the cooking equipment, the more food residues and other dirt inside the cooking cavity tend to be. Compared with non-meat recipes, meat recipes have a higher fat content. During the cooking process of meat recipes, oil stains are more likely to adhere to the inside of the cooking cavity, making the degree of dirt inside the cooking cavity after cooking meat recipes higher than after cooking non-meat recipes. Therefore, the microwave cleaning power, that is, the preset power of the microwave transmitter, is determined according to the cooking time of meat recipes and the cooking time of non-meat recipes respectively, so that the preset power of the microwave transmitter matches the degree of dirt inside the cooking cavity, so as to avoid the unreasonable preset power of the microwave transmitter resulting in the dirt inside the cooking cavity cannot be completely decomposed and carbonized, which in turn leads to unsatisfactory cleaning effect and affects user experience.

[0079] In some embodiments, the preset power and the cooking time of a meat recipe satisfy a monotonically increasing relationship, and the preset power and the cooking time of a non-meat recipe also satisfy a monotonically increasing relationship.

[0080] In some embodiments, the preset power may also be customized by the user when the cooking device is required to perform microwave cleaning. The preset power may also be dynamically adjusted by the cooking device according to the degree of dirtiness inside the cooking cavity during the microwave cleaning process.

[0081] based on Figure 4 The illustrated embodiments bring at least the following beneficial effects: the present application provides a cooking device, which is provided with a microwave transmitter, and the operation of the microwave transmitter can evaporate and carbonize food residues inside the cooking cavity of the cooking device, and the user can easily clean the carbonized products of the food residues with a rag, and the cooking cavity of the cooking device can be cleaned without water resources, thereby improving the intelligence level of the cooking device and saving water resources at the same time.

[0082] In some embodiments, Figure 5 As shown, step S102 can be specifically implemented as the following steps:

[0083] S1021. In response to the control instruction, detect whether the door is closed.

[0084] S1022. When the door is closed, control the microwave transmitter to operate at a preset power until the operating time of the microwave transmitter reaches a preset operating time.

[0085] In some embodiments, when it is confirmed that the door is closed, the microwave transmitter can be controlled to operate at a preset power until the working time of the microwave transmitter reaches the preset working time and then stops working to complete the microwave cleaning process.

[0086] In some embodiments, the cooking device is equipped with a voice prompt device. When it is confirmed that the door is not closed, the cooking device can use voice to remind the user to close the door.

[0087] In some embodiments, after the microwave emitter stops working when the working time reaches the preset working time, the cooking device can remind the user by voice that the microwave cleaning is completed. After the microwave cleaning is completed, the user can clean the carbonized products of food residues in the cooking cavity with a rag.

[0088] It is understandable that if the microwaves output by the microwave transmitter are absorbed by the human body, they will burn human skin tissue. If they are absorbed by non-metallic products outside the cooking cavity, they may cause the non-metallic products to be scalded. Therefore, in order to avoid safety hazards, it is necessary to detect whether the door is closed before controlling the operation of the microwave transmitter. Only when the door is closed, that is, when the cooking cavity is a closed space, can the microwave transmitter be controlled to operate.

[0089] In some embodiments, the microwave transmitter includes a first magnetron, a second magnetron and a booster, wherein the first magnetron and the second magnetron are used to output microwaves, and the booster is used to provide working voltage for the first magnetron and the second magnetron. Figure 6 As shown, step S1022 can be specifically implemented as the following steps:

[0090] S10221: Control the first magnetron and the second magnetron to work alternately.

[0091] In some embodiments, when it is confirmed that the door is closed, the first magnetron and the second magnetron of the microwave transmitter can be controlled to work alternately until the working time of the microwave transmitter reaches a preset working time and stops working.

[0092] In some embodiments, Figure 7 As shown, step S10221 can be specifically implemented as the following steps:

[0093] Step N1: When the temperature value of the first magnetron is greater than the temperature threshold, or the working time of the first magnetron reaches a first sub-time, the first magnetron is controlled to stop working, and the second magnetron is controlled to work.

[0094] The temperature threshold is the protection temperature of the first magnetron and the second magnetron. The protection temperature of the first magnetron and the second magnetron may be predefined when the first magnetron and the second magnetron leave the factory. For example, the protection temperature of the first magnetron and the second magnetron may be 500°C, that is, the temperature threshold may be 500°C.

[0095] In some embodiments, the first sub-time length is the longest time that the first magnetron works within the protection temperature. The first sub-time length may be customized or pre-defined when the first magnetron leaves the factory. For example, the first sub-time length may be 10 minutes.

[0096] Step N2: When the temperature value of the second magnetron is greater than the temperature threshold, or the working time of the second magnetron reaches the second sub-time length, the second magnetron is controlled to stop working, and the first magnetron is controlled to work.

[0097] Among them, the description of the temperature threshold can refer to the relevant description of the above step X1, which will not be repeated here.

[0098] In some embodiments, the second sub-time length is the maximum time that the second magnetron works within the protection temperature. The second sub-time length may be customized or pre-defined when the second magnetron leaves the factory. For example, the second sub-time length may be 10 minutes.

[0099] It should be understood that when the temperature is too high or the continuous working time is too long, the service life of the first magnetron and the second magnetron will be shortened, thereby affecting the service life of the cooking device. Therefore, when the temperature value of the first magnetron is greater than the temperature threshold, or the working time of the first magnetron reaches the first sub-time length, the first magnetron is controlled to stop working and the second magnetron is controlled to work. When the temperature value of the second magnetron is greater than the temperature threshold, or the working time of the second magnetron reaches the second sub-time length, the second magnetron is controlled to stop working and the first magnetron is controlled to work. This can extend the service life of the first magnetron and the second magnetron. That is, controlling the first magnetron and the second magnetron to work alternately can extend the service life of the first magnetron and the second magnetron, thereby extending the service life of the cooking device.

[0100] In some embodiments, Figure 8 As shown, the microwave transmitter 104 of the cooking device 10 may further include a third magnetron 1043 and a fourth magnetron 1044 .

[0101] In some embodiments, when the cooking device performs the microwave cleaning function, the controller can control the first magnetron, the second magnetron, the third magnetron and the fourth magnetron to work alternately, such as Fig. 9 As shown, it can be implemented as follows:

[0102] Step M1: When the temperature value of the first magnetron is greater than the temperature threshold, or the working time of the first magnetron reaches a first sub-time, the first magnetron is controlled to stop working, and the second magnetron is controlled to work.

[0103] In some embodiments, the description of step M1 may refer to the relevant description of the above step N1 and will not be repeated here.

[0104] It should be noted that the temperature threshold is the protection temperature of the first magnetron, the second magnetron, the third magnetron and the fourth magnetron. For the description of the protection temperature, refer to the relevant description of the above step N1, which will not be repeated here.

[0105] Step M2: When the temperature value of the second magnetron is greater than the temperature threshold, or the working time of the second magnetron reaches the second sub-time length, the second magnetron is controlled to stop working, and the third magnetron is controlled to work.

[0106] Among them, the description of the second sub-time length can refer to the relevant description of the above step N2, which will not be repeated here.

[0107] Step M3: when the temperature value of the third magnetron is greater than the temperature threshold, or the working time of the third magnetron reaches the third sub-time, the third magnetron is controlled to stop working, and the fourth magnetron is controlled to work.

[0108] In some embodiments, the third sub-time length is the maximum time that the third magnetron works within the protection temperature. The third sub-time length may be customized or pre-defined when the third magnetron leaves the factory. For example, the third sub-time length may be 10 minutes.

[0109] Step M4: when the temperature value of the fourth magnetron is greater than the temperature threshold, or the working time of the fourth magnetron reaches a fourth sub-time, the fourth magnetron is controlled to stop working, and the first magnetron is controlled to work.

[0110] In some embodiments, the fourth sub-time length is the maximum time that the fourth magnetron works within the protection temperature. The fourth sub-time length may be customized or pre-defined when the fourth magnetron leaves the factory. For example, the fourth sub-time length may be 10 minutes.

[0111] It can be understood that the more magnetrons the microwave emitter of the cooking device includes, the longer the service life of the microwave emitter is, and thus the longer the service life of the cooking device is.

[0112] In some embodiments, when the microwave transmitter of the cooking device includes a plurality of magnetrons, damage to some of the magnetrons will not affect the microwave cleaning function of the cooking device, that is, will not affect the service life of the cooking device.

[0113] In some embodiments, the controller of the cooking device can control the microwave emitter to operate under preset conditions to clean the cooking cavity.

[0114] As a possible example, the preset condition may be that the cooking device cooks a first preset number of meat recipes and / or a second preset number of non-meat recipes after completing the microwave cleaning process. That is, when the cooking device cooks a first preset number of meat recipes and / or a second preset number of non-meat recipes after completing the microwave cleaning process, the controller may control the microwave launcher to operate so as to clean the cooking cavity.

[0115] The first preset number is smaller than the second preset number. The first preset number and the second preset number may be preset when the cooking device leaves the factory. For example, the first preset number may be 10 and the second preset number may be 20.

[0116] like Fig.10 As shown, it can be implemented as follows:

[0117] S201. Obtain the cooking quantity of a meat recipe.

[0118] In some embodiments, the controller may periodically obtain the cooking quantity of the meat recipe from the memory, for example, the cooking quantity of the meat recipe may be obtained from the memory every 12 hours, and the cooking quantity of the meat recipe will restart from 0 after the cooking device completes the microwave cleaning process.

[0119] S202: Obtain the cooking quantity of the non-meat recipe.

[0120] In some embodiments, the controller may periodically obtain the cooking quantity of non-meat recipes from the memory, for example, the cooking quantity of non-meat recipes may be obtained from the memory every 12 hours, and the cooking quantity of non-meat recipes starts counting from 0 again after the cooking device completes the microwave cleaning process.

[0121] S203: When the cooking quantity of the meat recipe is greater than or equal to the first preset quantity and / or the cooking quantity of the non-meat recipe is greater than or equal to the second preset quantity, control the microwave transmitter to operate to clean the cooking cavity.

[0122] In some embodiments, the description of the first preset number and the second preset number can refer to the relevant description of the above examples and will not be repeated here.

[0123] As another possible example, the preset condition may be a preset time after the cooking device completes the microwave cleaning process. For example, the preset condition may be 10 days after the cooking device completes the microwave cleaning process, which is equivalent to the cooking device automatically performing the microwave cleaning process once every 10 days when powered on. Fig.11 As shown, it can be implemented as follows:

[0124] S301, obtaining the number of days the cooking equipment is used.

[0125] The number of days the cooking device is used is the number of days the cooking device is used after the microwave cleaning process is completed. The number of days the cooking device is used starts again from 0 after the cooking device completes the microwave cleaning process.

[0126] In some embodiments, the cooking device can be connected to the Internet, and the controller can obtain the date of the last microwave cleaning process from the memory and the current date from the Internet. The number of days the cooking device has been used can be determined based on the date of the last microwave cleaning process and the current date.

[0127] S302: When the cooking device has been used for more than or equal to a preset number of days, control the microwave transmitter to operate so as to clean the cooking cavity.

[0128] In some embodiments, the description of the preset number of days can refer to the relevant description of the above examples and will not be repeated here.

[0129] It can be understood that in the above examples, the microwave transmitter is controlled to operate to clean the cooking cavity when the door of the cooking device is closed.

[0130] A control method for a cooking device provided in the present application is described below with reference to a specific example. Fig.12 A flow chart of a control method for a cooking device provided in an embodiment of the present application, wherein the method is applied to a controller of the cooking device.

[0131] like Fig.12 As shown, when the cooking device starts to clean the cooking cavity, the historical cooking data of the cooking device is first obtained from the memory, and then the preset power and preset working time of the microwave transmitter are matched according to the historical cooking data of the cooking device.

[0132] Among them, the preset power can also be understood as the working power, and the preset working time can also be understood as the cleaning time. The description of the preset power, preset working time and historical cooking data of the cooking equipment can refer to the relevant description in the above step S102, which will not be repeated here.

[0133] Then, it is determined whether the door of the cooking device is closed. If the door is not closed, a voice prompt is given to remind the user to close the door of the cooking device. If the user does not close the door of the cooking device within the waiting time, the microwave cleaning process is not performed. When the door is closed, the first magnetron is started. The first magnetron is one of the magnetrons of the microwave transmitter. The magnetron can also be expressed as a microwave module. If the user closes the door of the cooking device within the waiting time, the next step is performed. The waiting time can be pre-defined when the cooking device leaves the factory. For example, the waiting time can be 5 minutes.

[0134] Then, it is determined whether the working time of the microwave transmitter reaches the preset working time. If the working time of the microwave transmitter reaches the preset working time, the cooking device is controlled to end the microwave cleaning process. If the working time of the microwave transmitter does not reach the preset working time, it is determined whether the temperature value of the first magnetron is greater than or equal to the protection temperature. The description of the protection temperature can refer to the relevant description of the above step N1, which is not repeated here.

[0135] When the temperature value of the first magnetron is greater than or equal to the protection temperature, the first magnetron is controlled to stop working, and the second magnetron is controlled to start working, that is, the currently working magnetron is controlled to stop working, and the other magnetron is controlled to start working. When the temperature value of the first magnetron is less than the protection temperature, the working time of the first magnetron is recorded and it is determined whether the working time of the first magnetron reaches the first sub-time. The description of the first sub-time can refer to the relevant description of the above step N1, which is not repeated here.

[0136] When the working time of the first magnetron does not reach the first sub-time length, it is re-determined whether the working time of the microwave transmitter reaches the preset working time length. When the working time of the first magnetron reaches the first sub-time length, the first magnetron is controlled to stop working, and the second magnetron is controlled to start working, that is, the currently working magnetron is controlled to stop working, and the other magnetron is controlled to start working.

[0137] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
