[0002] As people's living standards improve, users' requirements for home cooking are also gradually increasing, and users are looking forward to using cooking equipment to cook better quality food.

[0003] In the process of intelligent cooking by a cooking device, the temperature control effect of the cooking device is crucial. Usually, the temperature in the cooking cavity may be too high due to untimely regulation.

[0004] In order to ensure the temperature control effect of the cooking device, if the heating device is frequently started and stopped, the relay of the cooking device may be damaged, which may reduce the service life of the cooking device. Therefore, a temperature control solution that can extend the service life of the cooking device is urgently needed. Summary of the invention

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] In the related art, the temperature control effect of the cooking device is often ensured by frequently controlling the start and stop of the heating device. However, frequently controlling the start and stop state of the heating device will accelerate the wear rate of the relay in the cooking device, which may reduce the service life of the cooking device.

[0046] In addition, existing cooking devices often control the temperature after the temperature in the cooking cavity is higher than the target temperature, which may cause a serious temperature overshoot, making the actual temperature higher than the target temperature. Figure 1 As shown, it often takes too long to stabilize the temperature in the cooking cavity after the temperature overshoots, which may affect the cooking effect of the cooking device.

[0047] Based on this, the present application provides a cooking device, which can monitor the temperature change in the cooking cavity by obtaining the temperature value in the cooking cavity through a temperature detection device at the end of the P-1th cycle after the cooking starts. According to the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, the cycle length of the Pth cycle is determined, which can avoid a cooking cycle that is too long or too short, thereby avoiding the load and loss of the cooking cycle reduction relay caused by using a longer cooking cycle when the difference is large.

[0048] Furthermore, based on the relationship between the temperature value in the cooking chamber at the end of the P-1th cycle and the target temperature value, the working state of the heating device during the cycle duration of the P-1th cycle is adjusted through a relay to ensure the temperature control effect of the cooking equipment, thereby ensuring the cooking effect of the cooking equipment.

[0049] In general, the present application achieves the purpose of reducing the load and loss of the relay while ensuring the temperature control effect, thereby reducing the loss rate of the relay and extending the service life of the cooking equipment.

[0050] To further describe the solution of the present application, the cooking device is an oven as an example, and a cooking device provided in an embodiment of the present application is described in conjunction with the accompanying drawings. In the embodiment of the present application, the oven is a cooking device with a baking function or a steam heating function. For example, the oven can be an electric oven, an integrated stove with an oven function, etc., without limitation.

[0051] To further describe the solution of this application, Figure 2 This is a schematic diagram of the overall structure of an oven provided in an embodiment of the present application. Figure 2 As shown, the oven includes: a box body 101, a door body 102 and a control panel 103.

[0052] In some embodiments, a cooking cavity with an opening on one side is formed inside the cabinet 101 .

[0053] In some embodiments, the door body 102 is disposed at the opening of the cooking cavity to cover the opening of the cooking cavity.

[0054] In some embodiments, a door switch sensing device 1021 is further provided on the door body 102, and the door switch sensing device is used to detect whether the door body is closed.

[0055] In some embodiments, the door switch sensing device 1021 may also be disposed on the box body 101, and this application does not impose any specific limitation on this.

[0056] In some embodiments, the control panel 103 is placed on the box 101 and located above the door.

[0057] In some embodiments, the control panel 103 may also be replaced by devices such as buttons, keys or knobs with specific functions, and this application does not impose any specific restrictions on this.

[0058] In some embodiments, the user can send control instructions to the cooking device through the control panel 103; the control panel 103 can be a touch panel or a mechanical panel, etc., and this application does not impose any specific restrictions on this.

[0059] See also Figure 3 As shown, the cooking device provided in the embodiment of the present application may further include: a heating device 104.

[0060] In some embodiments, the heating device 104 may be disposed at a location such as the bottom of the cooking cavity, and this application does not impose any specific limitation on this.

[0061] In some embodiments, the heating device 104 may be a heating tube, which passes an electric current through the heating wire to generate heat. The heat is transferred to the food in the cooking cavity through air convection to achieve the purpose of cooking and heating. The working principle of the heating tube is based on resistive heating. By controlling the current and temperature, the heating effect of the oven can be adjusted to achieve different cooking needs.

[0062] See also Figure 4 As shown, the cooking device provided in the embodiment of the present application may further include: a relay 105 and a controller 106.

[0063] In some embodiments, the relay 105 may be an electromagnetic relay. The working principle of the electromagnetic relay is based on electromagnetic attraction and the operation of a mechanical switch: when the electromagnetic coil of the relay is energized, the generated magnetic field attracts the core of the mechanical switch to move, thereby changing the state of the contact.

[0064] When the contacts of the electromagnetic relay are closed, the relay circuit is connected, and the current flows to make the heating device work; when the contacts are open, the relay circuit is disconnected, and the current cannot flow, thus stopping the heating device from working. This method realizes the control and protection of the heating device, ensuring that the oven works normally within the set temperature and time range.

[0065] In some embodiments, see Figure 5 As shown, the relay 105 is electrically connected to the heating device 104 and the controller 106 respectively. The controller 106 controls the working state of the heating device 104 through the relay 105. When the relay 105 is in a closed state, the heating device 104 is in an operating state; when the relay 105 is in a disconnected state, the heating device 104 is in a closed state.

[0066] See also Figure 6 As shown, the cooking device provided in the embodiment of the present application may further include a temperature detection device 107 , and the controller 106 is further electrically connected to the temperature detection device 107 of the control panel 103 .

[0067] In some embodiments, the temperature detection device 107 is used to detect the temperature in the cooking cavity. The temperature detection device 108 is disposed on the cooking cavity.

[0068] In some embodiments, the temperature detection device 107 may be a thermistor, a thermocouple or a temperature sensor, and the present application does not impose any specific restrictions on this. Taking the temperature detection device 107 as a thermistor as an example, the working principle of the thermistor is based on the property that the resistance of the material changes with temperature, and the temperature change is inferred by measuring the change in resistance.

[0069] In some embodiments, the controller 106 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 to execute the control instruction. Exemplarily, the controller 106 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 106 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.

[0070] In some embodiments, the controller 106 responds to the control instruction sent by the control panel 103 and performs the cooking task indicated by the control instruction.

[0071] In some embodiments, the controller 106 is configured as follows: after cooking starts, at the end of the P-1th cycle, obtaining the temperature value in the cooking cavity through a temperature detection device, where P is a positive integer greater than 1; determining the cycle duration of the Pth cycle based on the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, and the relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value; and adjusting the working state of the heating device during the cycle duration of the Pth cycle through a relay based on the relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value.

[0072] According to the above content, after the cooking starts, the temperature value in the cooking cavity is obtained by the temperature detection device at the end of the P-1th cycle, and the temperature change in the cooking cavity can be monitored. According to the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, the cycle length of the Pth cycle is determined, which can avoid too long or too short cooking cycles, thereby reducing the load and loss of the relay.

[0073] Furthermore, according to the relationship between the temperature value in the cooking chamber at the end of the P-1th cycle and the target temperature value, the working state of the heating device during the cycle duration of the P-1th cycle is adjusted through the relay to ensure the temperature control effect of the cooking equipment.

[0074] In general, the present application achieves the purpose of reducing the load and loss of the relay while ensuring the temperature control effect, thereby reducing the loss rate of the relay and extending the service life of the cooking equipment.

[0075] In some embodiments, the controller 106 is configured to determine the cycle duration of the P-th cycle based on the difference between the temperature value in the cooking cavity at the end of the P-1-th cycle and the target temperature value, as well as the size relationship between the temperature value in the cooking cavity at the end of the P-1-th cycle and the target temperature value. Specifically, it is configured as follows: determine the duration coefficient of the P-th cycle based on the difference between the temperature value in the cooking cavity at the end of the P-1-th cycle and the target temperature value, as well as the size relationship between the temperature value in the cooking cavity at the end of the P-1-th cycle and the target temperature value; determine the cycle duration of the P-th cycle based on the duration coefficient of the P-th cycle and the preset duration.

[0076] According to the above content, the present application determines the duration coefficient of the Pth cycle according to the difference between the temperature value in the cooking chamber at the end of the P-1th cycle and the target temperature value, and the size relationship between the temperature value in the cooking chamber at the end of the P-1th cycle and the target temperature value, which helps to determine the cycle duration of the Pth cycle. Determining the cycle duration of the Pth cycle according to the duration coefficient of the Pth cycle and the preset duration can avoid the cycle duration of the Pth cycle being too long or too short, thereby reducing the load and loss of the relay.

[0077] In some embodiments, the controller 106 is configured to determine the duration coefficient of the P-th cycle based on the difference between the temperature value in the cooking cavity at the end of the P-1-th cycle and the target temperature value, and the size relationship between the temperature value in the cooking cavity at the end of the P-1-th cycle and the target temperature value. The controller 106 is specifically configured as follows: when the temperature value in the cooking cavity at the end of the P-1-th cycle satisfies a first preset condition, the duration coefficient of the P-th cycle is determined to be a first coefficient, and the first preset condition includes that the temperature value in the cooking cavity at the end of the cycle is above the target temperature value, and the difference between the temperature value in the cooking cavity at the end of the cycle and the target temperature value is above a first threshold value; when the temperature value in the cooking cavity at the end of the P-1-th cycle satisfies a second preset condition, the duration coefficient of the P-th cycle is determined to be a first coefficient. The duration coefficient is the first coefficient, and the second preset condition includes that the temperature value in the cooking cavity at the end of the cycle is below the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the cycle is above the second threshold; when the temperature value in the cooking cavity at the end of the P-1th cycle satisfies the third preset condition, the duration coefficient of the Pth cycle is determined to be the second coefficient, and the third preset condition includes that the temperature value in the cooking cavity at the end of the cycle is above the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the cycle is below the first threshold, or, if the temperature value in the cooking cavity at the end of the cycle is below the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the cycle is below the second threshold, the second coefficient is below the first coefficient.

[0078] According to the above content, when the temperature value in the cooking cavity is above the target temperature value at the end of the P-1th cycle, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is above the first threshold value, or when the temperature value in the cooking cavity is below the target temperature value at the end of the P-1th cycle, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is above the second threshold value, it means that the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is large. It should be understood that when the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is large, determining the duration coefficient of the Pth cycle to be the first coefficient helps to avoid the Pth cycle duration being too short, thereby helping to reduce the load and loss of the relay.

[0079] Further, if the temperature value in the cooking cavity at the end of the P-1th cycle is above the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is below the first threshold, or if the temperature value in the cooking cavity at the end of the P-1th cycle is below the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is below the second threshold, it means that the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is small. It should be understood that when the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value is small, determining the duration coefficient of the Pth cycle to be the second coefficient helps to avoid the Pth cycle duration being too long, thereby helping to make the temperature in the cooking cavity tend to be stable as soon as possible.

[0080] In some embodiments, when the temperature value in the cooking chamber meets the third preset condition at the end of the P-1th cycle, the controller 106 is further configured to: reset the count value to 0, the count value is equal to the target number of cycles in the P-1th cycle, and the target cycle represents the number of cycles that meet the first preset condition or the second preset condition.

[0081] According to the above content, when the temperature value in the cooking chamber meets the third preset condition at the end of the P-1th cycle, it means that the temperature value in the cooking chamber at the end of the P-1th cycle is close to the target temperature value. At this time, the count value is reset to 0, which helps to extend the cycle length of the P+1th cycle when the temperature in the cooking chamber tends to be stable, thereby helping to reduce the load and loss of the relay.

[0082] In some embodiments, the controller 106 is further configured to: obtain the temperature value in the cooking cavity through a temperature detection device at the end of the Pth cycle; when the count value is 0 and the temperature value in the cooking cavity at the end of the Pth cycle satisfies a third preset condition, determine that the duration coefficient of the P+1th cycle is the third coefficient, and the third coefficient is greater than the first coefficient; determine the cycle duration of the P+1th cycle based on the third coefficient and the preset duration; and adjust the working state of the heating device during the cycle duration of the P+1th cycle through a relay based on the relationship between the temperature value in the cooking cavity at the end of the Pth cycle and the target temperature value.

[0083] According to the above content, when the count value is 0 and the temperature value in the cooking cavity at the end of the Pth cycle meets the third preset condition, it means that the temperature value in the cooking cavity has stabilized. At this time, the duration coefficient of the P+1th cycle is determined to be a third coefficient greater than the first coefficient to avoid the cycle duration of the P+1th cycle being too short. It should be understood that after determining the cycle duration of the P+1th cycle according to the third coefficient, according to the relationship between the temperature value in the cooking cavity at the end of the Pth cycle and the target temperature value, adjusting the working state of the heating device during the cycle duration of the P+1th cycle through the relay helps to ensure the temperature control effect of the cooking device in the P+1th cycle.

[0084] In some embodiments, the controller 106 is configured to adjust the working state of the heating device during the cycle duration of the P-th cycle through a relay based on the relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value. Specifically, the controller 106 is configured as follows: if the temperature value in the cooking cavity at the end of the P-1th cycle is above the target temperature value, the heating device is adjusted to an off state through a relay during the cycle duration of the P-th cycle; if the temperature value in the cooking cavity at the end of the P-1th cycle is below the target temperature value, the heating device is adjusted to an on state through a relay during the cycle duration of the P-th cycle.

[0085] According to the above content, when the temperature value in the cooking cavity is above the target temperature value at the end of the P-1th cycle, the heating device is adjusted to the off state through the relay during the cycle duration of the Pth cycle to avoid overheating the food in the cooking cavity when the temperature in the cooking cavity is higher than the target temperature value. When the temperature value in the cooking cavity is below the target temperature value at the end of the P-1th cycle, the heating device is adjusted to the on state through the relay during the cycle duration of the Pth cycle to heat the food in the cooking cavity, thereby ensuring the heating effect of the cooking device.

[0086] In some embodiments, the cooking device also has a communicator, which is connected to the controller 106 and is used to establish a communication connection with other network entities. Taking the RF module as an example, the RF module can be used to receive and send signals, especially to send the received information to the controller 106 for processing; in addition, the signal generated by the controller is sent out. Generally, the RF circuit can include but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc.

[0087] For example, the cooking device may receive a control instruction sent by the terminal device through the communicator, and perform corresponding processing according to the control instruction to realize interaction between the user and the cooking device.

[0088] Figure 7 This is a schematic diagram of interaction between an oven controller 106 and a terminal device according to an exemplary embodiment of the present application.

[0089] like Figure 7 As shown, the terminal device can establish a communication connection with the controller 106 of the oven. Exemplarily, any known network communication protocol can be used to establish the communication connection. The above-mentioned network communication protocol can be various wired or wireless communication protocols, such as Ethernet, universal serial bus (USB), FireWire (FIREWIRE), any cellular network communication protocol (such as 3G / 4G / 5G), Bluetooth, wireless fidelity (wireless fidelity, Wi-Fi), NFC or any other suitable communication protocol. The above-mentioned communication connection can be a Bluetooth connection, NFC, Zigbee, wireless fidelity (wireless fidelity, Wi-Fi), etc. The embodiment of the present application does not specifically limit this.

[0090] It should be noted that Figure 7 The terminal device shown is only an example of a terminal device. The terminal device in this application can be a remote control, a mobile phone, a tablet computer, a personal computer (PC), a personal digital assistant (PDA), a smart watch, a netbook, a wearable electronic device, an augmented reality (AR) device, a virtual reality (VR) device, a robot, etc. This application does not impose any special restrictions on the specific form of the terminal device.

[0091] It is understood that the structure illustrated in the embodiment of the present invention does not constitute a specific limitation on the cooking device. In other embodiments of the present application, the cooking device may include more or fewer components than shown in the figure, or combine some components, or separate 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.

[0092] The following is a detailed introduction to the embodiments of the present application in conjunction with the accompanying drawings.

[0093] like Figure 8 As shown, an embodiment of the present application provides a control method for a cooking device, the method is applied to a controller, and the controller may be the controller 106 in the oven described above. The method may include the following steps:

[0094] S101. After starting cooking, at the end of the P-1th cycle, obtain the temperature value in the cooking cavity.

[0095] In some embodiments, after cooking begins, in order to monitor the temperature change in the cooking cavity, at the end of the P-1th cycle, the controller obtains the temperature value in the cooking cavity through the temperature detection device.

[0096] It should be noted that, when the controller detects that the heating device of the cooking device starts to work, it is determined that the cooking device starts cooking.

[0097] S102, determining the cycle length of the Pth cycle according to the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, and the relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value.

[0098] The target temperature value is preset by the user before starting cooking, for example, the target temperature value is 180 degrees Celsius.

[0099] It should be noted that the duration of the first cycle can be pre-set by relevant staff when the cooking equipment leaves the factory, and can also be set by the user before starting cooking. This application does not impose any specific restrictions on this.

[0100] In some embodiments, in order to avoid the cooking cycle being too long or too short, after obtaining the temperature value in the cooking cavity at the end of the P-1th cycle, the cycle duration of the Pth cycle is determined based on the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, and the relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value.

[0101] As an example, see Fig. 9 As shown, the above S102 can be specifically implemented as the following steps:

[0102] S201. Determine a duration coefficient of the Pth cycle according to a difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, and a magnitude relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value.

[0103] In some embodiments, the duration coefficient of the Pth cycle is determined based on the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, as well as the relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value. See S301-S303 below, which will not be repeated here.

[0104] S202: Determine the period duration of the Pth period according to the period duration coefficient of the Pth period and a preset period duration.

[0105] Among them, the preset time length is pre-set when the cooking equipment leaves the factory, and this application does not impose any specific restrictions on this.

[0106] As an example, the product of the duration coefficient of the Pth period and the preset duration may be determined as the period duration of the Pth period.

[0107] For example, assuming that the duration coefficient of the Pth cycle is 2 and the preset duration is 10 seconds, according to the duration coefficient of the Pth cycle and the preset duration, it can be determined that the cycle duration of the Pth cycle is 20 seconds.

[0108] based on Fig. 9 The embodiment shown at least brings the following beneficial effects: according to the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, and the size relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, the time coefficient of the Pth cycle is determined, which helps to determine the cycle time of the Pth cycle. According to the time coefficient of the Pth cycle and the preset time, the cycle time of the Pth cycle is determined, which can avoid the cycle time of the Pth cycle being too long or too short, thereby reducing the load and loss of the relay, so as to achieve the purpose of extending the service life of the cooking device.

[0109] In some embodiments, Fig.10 As shown, the above step S201 can be specifically implemented as the following steps:

[0110] S301: When the temperature value in the cooking cavity at the end of the P-1th cycle meets a first preset condition, determine that the duration coefficient of the Pth cycle is a first coefficient.

[0111] The first preset condition includes that the temperature value in the cooking cavity is above the target temperature value at the end of the cycle, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the cycle is above a first threshold.

[0112] It should be noted that the first preset condition and the first threshold are preset when the device leaves the factory; the first coefficient is a coefficient value determined by relevant staff that when the difference between the temperature value in the cooking chamber and the target temperature value is large, it will neither affect the temperature control effect of the cooking device nor increase the workload of the relay. For example, the first threshold may be 10 degrees Celsius, and the first coefficient may be 1, and this application does not impose any specific restrictions on this.

[0113] In some embodiments, at the end of the P-1th cycle, when the temperature value in the cooking cavity at the end of the P-1th cycle satisfies the second preset condition, it means that the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value is large. At this time, the controller determines that the duration coefficient of the Pth cycle is the first coefficient.

[0114] Exemplarily, the first threshold is 8 degrees Celsius, the first coefficient is 1, and the target temperature value is 160 degrees Celsius. The temperature value in the cooking cavity at the end of the P-1th cycle is 170 degrees Celsius; therefore, it can be seen that the temperature value in the cooking cavity at the end of the P-1th cycle is above the target temperature value, and the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value is greater than the first threshold, that is, the temperature value in the cooking cavity at the end of the P-1th cycle meets the first preset condition, and at this time, the duration coefficient of the Pth cycle is determined to be 1.

[0115] S302: When the temperature value in the cooking cavity meets the second preset condition at the end of the P-1th cycle, determine that the duration coefficient of the Pth cycle is the first coefficient.

[0116] The second preset condition includes that the temperature value in the cooking cavity is below the target temperature value at the end of the cycle, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the cycle is above a second threshold.

[0117] It should be noted that the above-mentioned second preset condition and second threshold are pre-set when the device leaves the factory, and the relationship between the second threshold and the first threshold is not specifically limited in this application.

[0118] In some embodiments, at the end of the P-1th cycle, when the temperature value in the cooking cavity at the end of the P-1th cycle satisfies the second preset condition, it means that the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value is large. At this time, the controller determines that the duration coefficient of the Pth cycle is the first coefficient.

[0119] Exemplarily, the second threshold is 10 degrees Celsius, the first coefficient is 1, and the target temperature value is 150 degrees Celsius. The temperature value in the cooking cavity at the end of the P-1th cycle is 135 degrees Celsius; therefore, it can be seen that the temperature value in the cooking cavity at the end of the P-1th cycle is below the target temperature value, and the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value is greater than the second threshold, that is, the temperature value in the cooking cavity at the end of the P-1th cycle meets the second preset condition, and the controller determines that the duration coefficient of the Pth cycle is 1.

[0120] S303: When the temperature value in the cooking cavity at the end of the P-1th cycle meets the third preset condition, determine that the duration coefficient of the Pth cycle is the second coefficient.

[0121] Among them, the above-mentioned third preset condition includes that the temperature value in the cooking cavity at the end of the cycle is above the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the cycle is below a first threshold, or, if the temperature value in the cooking cavity at the end of the cycle is below the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the cycle is below a second threshold, the second coefficient is below the first coefficient.

[0122] For example, the first coefficient may be 1, and the second coefficient may be 0.5, and this application does not impose any specific limitation on this.

[0123] It should be noted that the above-mentioned third preset condition and second coefficient are preset when the equipment leaves the factory, and this application does not impose any specific restrictions on this.

[0124] In some embodiments, during the cooking process, at the end of the P-1th cycle, if the temperature value in the cooking cavity at the end of the P-1th cycle meets the third preset condition, the duration coefficient of the Pth cycle is determined to be the second coefficient.

[0125] For example, assuming that the first threshold is 8 degrees Celsius, the second threshold is 10 degrees Celsius, the second coefficient is 0.5, and the target temperature value is 150 degrees Celsius. The temperature value in the cooking cavity at the end of the P-1th cycle is 145 degrees Celsius; therefore, it can be seen that the temperature value in the cooking cavity at the end of the P-1th cycle is below the target temperature value, and the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value is less than the second threshold, that is, the temperature value in the cooking cavity at the end of the P-1th cycle meets the third preset condition, and at this time, the duration coefficient of the Pth cycle is determined to be 0.5.

[0126] based on Fig.10The embodiment shown at least brings the following beneficial effects: when the temperature value in the cooking cavity at the end of the P-1th cycle is above the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is above the first threshold, or when the temperature value in the cooking cavity at the end of the P-1th cycle is below the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is above the second threshold, it indicates that the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is large. It should be understood that when the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value is large, determining the duration coefficient of the Pth cycle to be the first coefficient helps to avoid the Pth cycle duration being too short, thereby helping to reduce the load and loss of the relay.

[0127] Further, if the temperature value in the cooking cavity at the end of the P-1th cycle is above the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is below the first threshold, or if the temperature value in the cooking cavity at the end of the P-1th cycle is below the target temperature value, and the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is below the second threshold, it means that the difference between the temperature value in the cooking cavity and the target temperature value at the end of the P-1th cycle is small. It should be understood that when the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value is small, determining the duration coefficient of the Pth cycle to be the second coefficient helps to avoid the Pth cycle duration being too long, thereby helping to make the temperature in the cooking cavity tend to be stable as soon as possible.

[0128] S103, adjusting the working state of the heating device during the Pth cycle through a relay according to the relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value.

[0129] In some embodiments, during the cooking process, after determining the cycle duration of the Pth cycle, in order to ensure the cooking effect of the cooking equipment, the controller adjusts the working state of the heating device during the cycle duration of the Pth cycle through a relay based on the relationship between the temperature value in the cooking chamber at the end of the P-1th cycle and the target temperature value.

[0130] As an example, Fig.11 As shown, step S103 can be specifically implemented as the following steps:

[0131] S401: If the temperature value in the cooking cavity is above the target temperature value at the end of the P-1th cycle, the heating device is adjusted to an off state through a relay during the cycle duration of the Pth cycle.

[0132] In some embodiments, after determining the cycle duration of the Pth cycle, if the temperature value in the cooking chamber at the end of the P-1th cycle is above the target temperature value, the controller adjusts the heating device to an off state through a relay during the cycle duration of the Pth cycle to avoid overheating.

[0133] S402: If the temperature in the cooking chamber is below the target temperature at the end of the P-1th cycle, the heating device is adjusted to an on state through a relay during the cycle duration of the Pth cycle.

[0134] In some embodiments, after determining the cycle duration of the Pth cycle, if the temperature value in the cooking chamber is below the target temperature value at the end of the P-1th cycle, the controller adjusts the heating device to an on state through a relay during the cycle duration of the Pth cycle to ensure the heating effect of the cooking equipment.

[0135] It should be understood that, according to the above content, when the temperature value in the cooking cavity is above the target temperature value at the end of the P-1th cycle, the heating device is adjusted to the off state through the relay during the cycle length of the Pth cycle to avoid overheating the food in the cooking cavity when the temperature in the cooking cavity is higher than the target temperature value. When the temperature value in the cooking cavity is below the target temperature value at the end of the P-1th cycle, the heating device is adjusted to the on state through the relay during the cycle length of the Pth cycle to heat the food in the cooking cavity, thereby ensuring the heating effect of the cooking device.

[0136] According to the above content, the control method provided in the embodiment of the present application, the overall control process can be found in Fig.12 .

[0137] For example, Fig.13 The figure shows a schematic diagram of an optimized temperature curve provided in an embodiment of the present application.

[0138] See also Fig.13 After executing a control method for a cooking device provided in an embodiment of the present application, the temperature value of the cooking device gradually stabilizes about 3 minutes after reaching the peak value. Figure 1 It can be seen from the schematic diagram of the original temperature curve that the temperature value in the cooking cavity gradually stabilizes about 5 minutes after reaching the peak. It can be seen that the control method of the cooking device provided by the embodiment of the present application can make the temperature in the cooking cavity quickly stabilize after overshoot, thereby improving the temperature control effect of the cooking device and further improving the cooking effect of the cooking device.

[0139] In some embodiments, after cooking starts, if it is detected that the door of the cooking device is open, the controller controls the heating device to stop working; after detecting that the door of the cooking device is closed, the duration coefficient of the first cooking cycle after the door is closed is determined to be a preset coefficient, and the cycle duration of the cooking cycle and the state of the relay are adjusted according to the above S101-S103.

[0140] based on Figure 8 The embodiment shown at least brings the following beneficial effects: after starting cooking, the temperature value in the cooking cavity is obtained at the end of the P-1th cycle, and the temperature change in the cooking cavity can be monitored. According to the difference between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, and the size relationship between the temperature value in the cooking cavity at the end of the P-1th cycle and the target temperature value, the cycle length of the Pth cycle is determined, which can avoid too long or too short cooking cycles, thereby reducing the load and loss of the relay, thereby extending the service life of the cooking device.

[0141] Furthermore, according to the relationship between the temperature value in the cooking chamber at the end of the P-1th cycle and the target temperature value, the working state of the heating device during the cycle duration of the P-1th cycle is adjusted through the relay to ensure the temperature control effect of the cooking equipment.

[0142] In general, the present application achieves the purpose of reducing the load and loss of the relay while ensuring the temperature control effect, thereby reducing the loss rate of the relay and extending the service life of the cooking equipment.

[0143] See also Fig.14 As shown, when the temperature value in the cooking cavity meets the third preset condition at the end of the P-1th cycle, the control method of the cooking device provided by the embodiment of the present application further includes:

[0144] S501, returning the count value to 0, the count value being equal to the target number of cycles in the P-1th cycle, the target cycle representing the number of cycles that meet the first preset condition or the second preset condition.

[0145] based on Fig.14 The embodiment shown brings at least the following beneficial effects: when the temperature value in the cooking chamber meets the third preset condition at the end of the P-1th cycle, it means that the temperature value in the cooking chamber is close to the target temperature value at the end of the P-1th cycle. At this time, the count value is reset to 0, which helps to extend the cycle duration of the P+1th cycle when the temperature in the cooking chamber tends to be stable, thereby helping to reduce the load and loss of the relay.

[0146] In some embodiments, Fig.15 As shown, after the count value is reset to 0, the following steps are also included:

[0147] S601. At the end of the Pth cycle, obtain the temperature value in the cooking cavity.

[0148] In some embodiments, during the cooking process, at the end of the Pth cycle, a temperature value in the cooking cavity is acquired to monitor the temperature in the cooking cavity.

[0149] S602: When the count value is 0 and the temperature value in the cooking cavity at the end of the Pth cycle satisfies a third preset condition, determine that the duration coefficient of the P+1th cycle is the third coefficient.

[0150] Among them, the third coefficient is greater than the first coefficient.

[0151] It can be understood that since the preset duration is pre-set when the cooking equipment leaves the factory, the cycle duration is the product of the preset duration and the duration coefficient. Therefore, the larger the duration coefficient, the longer the cycle duration of the corresponding cycle.

[0152] In some embodiments, at the end of the Pth cycle, when the count value is 0 and the temperature value in the cooking cavity at the end of the Pth cycle meets the third preset condition, the controller determines the duration coefficient of the P+1th cycle to be the third coefficient.

[0153] based on Fig.15 The embodiment shown at least brings the following beneficial effects: when the count value is 0 and the temperature value in the cooking cavity satisfies the third preset condition at the end of the Pth cycle, it indicates that the temperature value in the cooking cavity has stabilized, and at this time, the duration coefficient of the P+1th cycle is determined to be a third coefficient greater than the first coefficient, so as to avoid the P+1th cycle duration being too short. It should be understood that avoiding the P+1th cycle duration being too short can avoid accelerating the loss rate of the relay due to excessive times of adjusting the heating device, thereby extending the service life of the cooking device.

[0154] See also Fig.16 As shown, the control method provided in the embodiment of the present application, after the above S602, further includes:

[0155] S603: Determine the period length of the P+1th period according to the third coefficient and the preset period length.

[0156] In some embodiments, at the end of the Pth cycle, when the duration coefficient of the P+1th cycle is determined to be the third coefficient, the controller determines the product of the third coefficient and the preset duration as the cycle duration of the P+1th cycle.

[0157] S604: According to the relationship between the temperature value in the cooking cavity at the end of the Pth cycle and the target temperature value, the working state of the heating device during the cycle duration of the P+1th cycle is adjusted through the relay.

[0158] In some embodiments, after determining the cycle duration of the P+1th cycle, in order to ensure the temperature control effect of the cooking equipment, the working state of the heating device during the cycle duration of the P+1th cycle is adjusted through a relay according to the relationship between the temperature value in the cooking chamber at the end of the Pth cycle and the target temperature value.

[0159] based on Fig.16 The embodiment shown brings at least the following beneficial effects: after determining the cycle duration of the P+1th cycle according to the third coefficient, the present application adjusts the working state of the heating device during the cycle duration of the Pth cycle through a relay according to the relationship between the temperature value in the cooking chamber at the end of the Pth cycle and the target temperature value, which helps to ensure the temperature control effect of the cooking equipment.
