Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a steam oven and a control method thereof. Background Art

[0002] With the development of society, people's living standards are constantly improving. Modern kitchen appliances with steam functions, such as steam ovens and steam boxes, have begun to be widely used in home cooking. Steam ovens can bake food and also steam and cook food. When baking food, the steam oven can use electric heating elements to convert electrical energy into thermal energy, so that the temperature inside the box is increased, and then the food is baked. When steaming and cooking food, a large amount of high-temperature water vapor fills the steam oven, and the high-temperature water vapor will heat the food.

[0003] However, during use, high-temperature steam will condense into water droplets when it encounters a lower temperature object. These water droplets may condense on the control panel to produce water droplets, or they may drip into the food, affecting the taste and appearance of the food. The steam oven in the related art adds a condensation chamber on the top, so that the steam enters the condensation chamber and condenses into condensed water for storage, thereby reducing the risk of condensed water dripping.

[0004] However, as the steam mode runs cumulatively, the condensed water in the condensation chamber accumulates continuously. When the amount of condensed water in the condensation chamber is relatively large, the condensed water will flow out through the air holes between the condensation chamber and the inner pot and flow into the inner pot. If cooking is in progress, it will drip onto the food being cooked, affecting the cooking effect. Or after the user opens the door after cooking is completed, the water in the condensation chamber will continue to drip, which will bring a bad user experience. Summary of the invention

[0044] 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.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0046] 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.

[0047] 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.

[0048] With the development of society, people's living standards are constantly improving. Modern kitchen appliances with steam functions, such as steam ovens and steam boxes, have begun to be widely used in home cooking. Steam ovens can bake food and also steam and cook food. When baking food, the steam oven can use electric heating elements to convert electrical energy into thermal energy, so that the temperature inside the box is increased, and then the food is baked. When steaming and cooking food, a large amount of high-temperature water vapor fills the steam oven, and the high-temperature water vapor will heat the food.

[0049] Figure 1 The mechanical structure diagram of a steam oven provided in a feasible embodiment is shown in FIG. Figure 1 As shown, the steam oven 10 may include: a housing 101, an inner tank 102, a door body 103, a steam generating assembly 104, a door switch sensor 105, a condensing chamber ( Figure 1 not shown).

[0050] In some embodiments, the housing 101 may be Figure 1 The shown one is approximately a rectangular parallelepiped, but other shapes are also possible.

[0051] In some embodiments, the inner pot 102 is disposed in the outer shell 101, and a baking cavity with an opening is formed inside the inner pot 102, and food materials that need to be processed can be placed in the baking cavity.

[0052] In some embodiments, the door 103 is hinged to the housing 101 through a hinge assembly, and when cooking is required, the inner pot 102 is opened by the door 103, the food to be cooked is placed in the inner pot 102, and then the door 103 is closed. In this way, a closed space is formed after the door 103 is closed, which can not only reduce heat dissipation but also avoid safety hazards such as burns caused by accidental touch by the user.

[0053] In some embodiments, Figure 2 As shown, the steam oven 10 provided by the present application, the steam generating assembly 104 includes an evaporation tube 210, a water supply device 220, a heat conductor 230 and a heating element 240. The first end of the evaporation tube 210 is in communication with the inner pot 102; the water supply device 220 is in communication with the second end of the evaporation tube 210, and the water supply device 220 is used to supply water into the evaporation tube 210; the heat conductor 230 is wrapped on the evaporation tube 210; the heating element 240 is in contact with the heat conductor 230 and is fixedly connected to the heat conductor 230.

[0054] Optionally, the steam generating component 104 can intermittently start heating or interrupt heating according to a temperature control method to ensure that the temperature in the inner pot 102 is consistent with the set temperature.

[0055] Exemplarily, when the set temperature is 120°C, the steam generating component 104 continues to heat and generate steam until the temperature in the cavity reaches 130°C and stops, and starts heating when it detects that the temperature in the inner pot is lower than 110°C, thereby ensuring that the temperature in the cavity remains at around 120°C.

[0056] In some embodiments, the door switch sensor 105 is disposed on the inner container 102 to detect the switch state of the door body 103. For example, if the door switch sensor 105 detects that the door body is opened and closed once, it can be determined that the door body 103 is in the closed state at this time.

[0057] In some embodiments, Figure 3 As shown, the condensation chamber 106 is connected to the steam-bake chamber in the inner container 102 through the air outlet 1021 at the top of the inner container 102. When the steam oven 10 is in operation, the steam in the steam-bake chamber can enter the condensation chamber 106 through the air outlet 1021 at the top of the inner container 102 and condense into condensed water. The condensation chamber 106 stores the condensed water to prevent the steam from condensing into water droplets when it is cold and dripping into the baking chamber of the steam oven 10.

[0058] In some embodiments, Figure 4 As shown, the steam oven 10 further includes: a display panel 107 , an operation panel 108 , a voice device 109 , a power supply 110 , and a controller 111 .

[0059] In some embodiments, the display panel 107 may be a liquid crystal display panel or an organic light-emitting diode (OLED) display panel. The specific type, size, and resolution of the display panel are not limited. The display panel 108 may be used to display the control panel of the oven. The oven may feedback the current working status of the oven through the display panel, such as being in a preheating state or a baking state.

[0060] For example, see Figure 5 The display panel 107 can display the cooking mode selected by the user (including cooking time and cooking temperature), the open or closed state of the door body 103 detected by the door switch sensor 105, the real-time oxygen content in the inner pot 102 detected by the oxygen sensor, the real-time temperature in the inner pot 102 and the remaining time corresponding to the cooking mode, etc.

[0061] In some embodiments, the operation panel 108 has function buttons. Exemplarily, the function buttons include a switch button, a mode selection button, a temperature selection button, + (increase button), - (decrease button), etc. In this way, the user can interact with the oven 11 through the operation panel 108 to adjust the mode, temperature, etc. of the steam oven 10.

[0062] In some embodiments, the voice device 109 is used to issue a prompt message. For example, if the door body 103 is in an open state when the user starts cooking, the voice device 109 issues a voice prompt message of "The door is not closed, please close the door!"

[0063] In some embodiments, the power supply 110 is disposed between the outer shell 101 and the inner pot 102, and is used to provide power supply support to the oven 11. The power supply 110 may include a built-in circuit installed inside the oven 11, or may be an external power supply installed in the steam oven 10, providing a power interface for an external power supply in the steam oven 10.

[0064] In some embodiments, Figure 6 As shown, the controller 111 is electrically connected to the steam generating assembly 104, the door switch sensor 105, the display panel 107, the operation panel 108, the voice device 109, and the power supply 110, and is used to generate an operation control signal according to the instruction operation code and the timing signal, and to instruct the steam oven 10 to execute the control instruction.

[0065] Exemplarily, the controller 111 may 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 111 may 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.

[0066] It is understood that the structure illustrated in the embodiment of the present invention does not constitute a specific limitation on the steam oven. In other embodiments of the present application, the steam oven 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.

[0067] As described in the background technology, when the steam oven is cooking food, the steam generating assembly 104 generates a large amount of high-temperature steam to heat the food. The high-temperature steam enters the condensation chamber 106 through the air outlet 1021 at the top of the inner pot 102 and condenses into condensed water. The condensation chamber 106 stores the condensed water, thereby reducing the risk of condensed water dripping.

[0068] However, as the steam mode runs cumulatively, the condensed water in the condensation chamber accumulates continuously. When the amount of condensed water in the condensation chamber is relatively large, the condensed water will flow out through the vent between the condensation chamber and the inner pot and flow into the inner pot. If cooking is in progress, it will drip onto the food being cooked, affecting the cooking effect. Or after the user opens the door after cooking is completed, the water in the condensation chamber will continue to drip, which will bring a bad user experience.

[0069] Based on this, see Figure 7 The steam oven 10 provided in the embodiment of the present application further includes an electric heating film 71.

[0070] In some embodiments, Figure 8 As shown, the electric heating film 71 can be arranged at the bottom of the inner wall of the condensation chamber 106 to heat the condensed water stored in the condensation chamber 106 .

[0071] As a feasible implementation method, the controller can drive the opening and closing of the relay through the relay driving module, thereby controlling the on and off of the load of the electric heating film 71.

[0072] As a possible implementation, see Fig. 9 The electric heating film 71 includes a heating component 711 and a thermal protector 712 .

[0073] The heating component 711 is used to heat the condensed water in the condensation chamber. As a feasible implementation method, the heating component 711 can be a nickel-chromium heating wire.

[0074] The thermal protector 712 is a mechanical temperature protection element. When the temperature is greater than or equal to the preset disconnection temperature, the internal metal spring will deform, the contact will be disconnected, the circuit will be disconnected, and the heating component 711 will stop heating. When the temperature drops to the preset disconnection temperature, the internal metal spring will resume its deformation, the contact will be reconnected, the circuit will be reconnected, and the heating component 711 will start heating.

[0075] That is, when the temperature of the thermal protector is lower than the preset disconnection temperature, it is in the on state, and the heating component 711 starts heating; when the temperature of the thermal protector is greater than or equal to the preset disconnection temperature, it is in the off state, and the heating component 711 stops heating.

[0076] In this way, the problem of the electric heating film 71 being continuously heated, which may cause the temperature in the condensation chamber to be too high, can be avoided.

[0077] See also Fig.10 In the steam oven 10 provided in the embodiment of the present application, the controller is configured to perform the following steps:

[0078] S1001. In response to receiving an operation instruction of a steam mode, obtaining a cooking time corresponding to the steam mode.

[0079] When a user uses a steam oven for cooking, he needs to select a steam-related mode on the operation interface and set the target temperature and cooking time when the steam oven is running. It should be understood that the embodiment of the present application does not limit the way in which the user selects the steam-related mode.

[0080] As a feasible implementation method, the user can select a steam-related mode on the control panel of the steam oven and set the target temperature and cooking time. As another feasible implementation method, the user can select a steam-related mode on a terminal device connected to the steam oven and set the target temperature and cooking time. The terminal device sends the user-configured data to the steam oven to enable the steam oven to operate.

[0081] S1002: If the cooking time is longer than the first preset time, the first operation time of the steam mode is counted.

[0082] It should be understood that the first preset time is pre-set by the system, and in actual applications, the first preset time can be set according to needs, and the embodiment of the present application does not impose any limitation on this. For example, as a feasible implementation method, the first preset time can be 10 minutes. If the cooking time set by the user is more than 10 minutes, the first running time of the steam mode operation is counted.

[0083] When the steam mode is running, condensed water will continue to accumulate in the condensation chamber. When the running time is long, the condensed water in the condensation chamber may overflow. Therefore, when the cooking time corresponding to the steam mode is greater than the first preset time, the first running time of the steam mode is counted.

[0084] S1003: When the first operating time reaches a first preset time, control the electric heating film to start heating.

[0085] When the running time of the steam mode reaches a first preset time, it is considered that there is a risk of overflow of the condensed water, and the electric heating film is controlled to start heating.

[0086] In some embodiments, the electric heating film will continue to heat up due to continuous operation, resulting in excessively high temperature in the condensation chamber, which will not condense the steam into condensed water. Alternatively, the thermal protector of the electric heating film may be frequently switched on and off, reducing the service life of the electric heating film.

[0087] Therefore, as a feasible implementation method, controlling the electric heating film to start heating can be specifically: controlling the electric heating film to heat for a second preset time at intervals of a first preset time.

[0088] It should be understood that the first preset time and the second preset time are preset by the system, and in practical applications, the first preset time and the second preset time can be set according to needs, and the embodiment of the present application does not impose any limitation on this. For example, as a feasible implementation method, the first preset time can be 10S and the second preset time can be 50S.

[0089] Controlling the electric heating film to heat for a second preset time at intervals of a first preset time, that is, making the electric heating film perform intermittent work, can avoid the problem of excessive temperature in the condensation chamber caused by continuous heating of the electric heating film, and further avoid the problem of steam being unable to condense in the condensation chamber and the thermal protector being frequently switched on and off, thereby extending the service life of the electric heating film.

[0090] It can be seen that in the steam oven provided in the embodiment of the present application, an electric heating film is provided at the bottom of the inner wall of the condensing chamber. In this way, after the user specifies that the steam oven runs the steam mode and sets the corresponding cooking time, the controller can judge whether the condensed water in the condensing chamber will overflow according to the relationship between the cooking time and the first preset time. When the cooking time is longer than the first preset time, it is determined that there is a risk of condensed water overflowing during the operation of the steam mode. When the operation time of the steam mode reaches the first preset time, the electric heating film is controlled to start heating, so that the condensed water in the condensing chamber evaporates and vaporizes and then dissipates to the outside of the steam oven.

[0091] That is to say, the steam oven provided in the embodiment of the present application, when the operating time of the steam mode reaches the first preset time, reduces the amount of condensed water in the condensation chamber through the electric heating film, thereby preventing the condensed water from overflowing and dripping onto the food being cooked, affecting the user experience.

[0092] In some embodiments, after the steam mode ends, although the steam generating assembly is no longer running, there is still a certain amount of condensed water in the condensation chamber. If the user moves the steam oven, the condensed water is likely to flow out, affecting the user experience. At the same time, the condensed water is likely to generate a large number of bacteria when stored for a long time, which is likely to contaminate the food cooked next time, causing food safety problems. Therefore, after the steam mode ends, the condensed water in the condensation chamber needs to be eliminated to prevent it from breeding bacteria.

[0093] As a possible implementation, see Fig.11 The controller provided in the embodiment of the present application is further configured to perform the following steps:

[0094] S1111. In response to the first operation duration reaching the cooking duration, counting the second operation duration at which the steam mode operation ends.

[0095] When the first operation time reaches the cooking time, that is, after the steam mode operation is completed, the second operation time after the steam mode operation is completed is counted.

[0096] S1102: When the second operating time reaches a second preset time, the electric heating film is controlled to stop heating.

[0097] It should be understood that the second preset duration is pre-set by the system, and in practical applications, the second preset duration can be set according to needs, and the embodiment of the present application does not impose any limitation on this. For example, as a feasible implementation method, the second preset duration can be 20 minutes, and when the second operating time reaches 20 minutes, the electric heating film is controlled to stop heating.

[0098] That is to say, at the end of the steam mode operation, the electric heating film is allowed to continue to heat and evaporate the condensed water in the condensation chamber until the duration of the steam mode operation ends reaches a second preset duration, and then it is determined that there is no condensed water in the condensation chamber, and the electric heating film is controlled to stop heating.

[0099] After the steam mode ends, the electric heating film is controlled to continue heating within the second preset time, and the electric heating film is controlled to stop heating when the second operation time reaches the second preset time. After the steam mode ends, the condensed water stored in the condensation chamber can be eliminated, which can prevent the condensed water from flowing out and affecting the user's experience. At the same time, it can prevent the condensed water from being stored for a long time to generate a large number of bacteria, thereby improving the user's experience.

[0100] In some embodiments, the inner pot of the steam oven generally further includes a temperature sensor for detecting the temperature inside the steam-bake cavity, and then the controller can control the operation of the steam generating assembly according to the temperature inside the cavity, so that the temperature inside the cavity can reach the target temperature set by the user. It is understandable that the higher the temperature inside the steam-bake cavity, the higher the temperature inside the condensing cavity, and then the higher the temperature of the electric heating film.

[0101] As a possible implementation, see Fig.12 , after S1101, the controller is further configured to:

[0102] S1201, obtaining the temperature inside the steaming and baking cavity.

[0103] Get the temperature inside the steam-bake cavity detected by the temperature sensor.

[0104] It should be understood that after the steam mode stops running, the temperature inside the steam oven is constantly changing. As a feasible implementation method, S1201 can be specifically implemented as: obtaining the cavity temperature of the steam oven cavity according to a preset frequency.

[0105] Exemplarily, the controller may obtain the temperature inside the steam-bake cavity once every minute after the steam mode ends.

[0106] S1202: Determine whether the temperature inside the steam-bake cavity is above a preset temperature threshold.

[0107] It should be understood that the preset temperature threshold is pre-set by the system, and in practical applications, the preset temperature threshold can be set according to requirements, and the embodiments of the present application do not impose any limitation on this. For example, as a feasible implementation method, the preset temperature threshold can be 180°C.

[0108] If the temperature in the cavity is above the preset temperature threshold, execute S1203; if not, execute S1204.

[0109] S1203, controlling the electric heating film to heat for a fourth preset time at intervals of the third preset time.

[0110] It should be understood that the third preset time and the fourth preset time are preset by the system, and the ratio of the third preset time to the fourth preset time is greater than the ratio of the first preset time to the second preset time. In practical applications, the third preset time and the fourth preset time can be set as required, and the embodiment of the present application does not impose any limitation on this. For example, as a feasible implementation method, the third preset time can be 90S, and the fourth preset time can be 60S.

[0111] It can be understood that the ratio of the third preset time to the fourth preset time and the ratio of the first preset time to the second preset time are the ratio of the stop time to the running time during the heating process of the electric heating film. The ratio of the third preset time to the fourth preset time is higher than the ratio of the first preset time to the second preset time, indicating that when the electric heating film is heated at intervals of the third preset time and runs for the fourth preset time, the proportion of stop operation is relatively large, that is, the actual heating time of the electric heating film is relatively short.

[0112] If the cavity temperature is above the preset temperature threshold, it indicates that the cavity temperature of the steaming and baking cavity is high, the cavity temperature of the condensing cavity is also high, and the temperature of the electric heating film is also high, which is easy to reach the disconnection temperature of the thermal protector in the electric heating film. When the electric heating film is heated, the electric heating film is controlled to heat for a fourth preset time every third preset time, that is, the actual heating time of the electric heating film is shorter, to prevent the temperature of the electric heating film from being too high, causing the thermal protector to be frequently turned on and off.

[0113] S1204, controlling the electric heating film to heat for a second preset time at intervals of the first preset time.

[0114] If the cavity temperature is below the preset temperature threshold, it indicates that the cavity temperature of the steaming and baking cavity is low, and thus the cavity temperature of the condensing cavity is also low. The electric heating film is controlled to heat for a second preset time every first preset time, that is, the actual heating time of the electric heating film is longer, so that the condensed water in the condensing cavity can be quickly evaporated into water vapor.

[0115] In some embodiments, if the cooking time of the steam mode selected by the user is less than the first preset time, there is no risk of condensed water in the condensation chamber overflowing. At this time, the electric heating film is not controlled to heat during the operation of the steam mode to avoid wasting energy. However, after the steam mode ends, although the steam generating component is no longer running, there is still a certain amount of condensed water in the condensation chamber. When the user moves the steam oven, the condensed water is easy to flow out. At the same time, the long-term storage of the condensed water is easy to generate a large number of bacteria, affecting the user's experience.

[0116] As a possible implementation, see Fig.13In the steam oven provided in the embodiment of the present application, after S1001, the controller is further configured to perform the following steps:

[0117] S1301: If the cooking time is less than the first preset time, in response to the end of the steam mode operation, the electric heating film is controlled to start heating.

[0118] After the steam mode ends, the electric heating film is controlled to start heating, so that the condensed water stored in the condensation chamber is vaporized and discharged from the steam oven.

[0119] As a feasible implementation method, S1201 can be specifically implemented as follows: if the cooking time is less than the first preset time, control the electric heating film to heat for a fourth preset time after heating for a fifth preset time at intervals of the third preset time.

[0120] It should be understood that the fifth preset time is preset by the system, and the third preset time and the fourth preset time can be set according to the needs in practical applications, and the embodiment of the present application does not make any limitation on this. For example, as a feasible implementation method, the fifth preset time can be 180S.

[0121] When the cooking time is less than the first preset time, since the electric heating film is not heated, the temperature of the electric heating film and the condensation chamber are both low. Therefore, after the steam mode operation ends, the electric heating film can be operated for a period of time to increase the temperature of the electric heating film to a certain temperature, and then intermittent heating is performed to better evaporate the condensed water in the condensation chamber into water vapor.

[0122] S1302, counting the second operation time after the steam mode operation ends.

[0123] S1303: When the second operating time reaches a second preset time, the electric heating film is controlled to stop heating.

[0124] That is to say, at the end of the steam mode operation, the electric heating film is used to heat and evaporate the condensed water in the condensation chamber until the duration of the steam mode operation ends reaches a second preset duration, and then it is determined that there is no condensed water in the condensation chamber, and the electric heating film is controlled to stop heating.

[0125] After the steam mode ends, the electric heating film is controlled to heat up within the second preset time, and when the second operation time reaches the second preset time, the electric heating film is controlled to stop heating. After the steam mode ends, the condensed water stored in the condensation chamber can be eliminated, which can prevent the condensed water from flowing out and affecting the user's experience. At the same time, it can prevent the condensed water from being stored for a long time to generate a large number of bacteria, thereby improving the user's experience.

[0126] In some embodiments, in order to allow steam to quickly discharge from the steam oven, a fan or other component may be used to promote air circulation, so that the steam can be quickly discharged from the steam oven to avoid steam accumulation inside the steam oven causing excessive air pressure inside the steam oven.

[0127] Based on this, see Fig.14 The steam oven 10 provided in the embodiment of the present application may further include: a cooling fan 112. Fig.14 As shown, the cooling fan 112 can be disposed at the condensing chamber 106 . After the cooling fan 112 starts to work, it can promote air circulation in the condensing chamber 106 , so that the steam in the condensing chamber 106 is discharged from the steam oven 10 .

[0128] As a possible implementation, see Fig.15 In the steam oven provided in the embodiment of the present application, after responding to receiving the operation instruction of the steam mode, the controller is further configured to:

[0129] S1501, control the cooling fan to start working.

[0130] When the steam mode operation instruction is received, in order to promote the discharge of water vapor from the steam oven, the cooling fan is controlled to start working to blow part of the water vapor out of the steam oven to avoid a large amount of water vapor condensing in the condensation chamber, resulting in excessive condensed water in the condensation chamber.

[0131] S1502: In response to the second operation time duration of the steam mode operation ending reaching the second preset time duration, control the cooling fan to stop working.

[0132] Since the electric heating film will continue to heat up after the steam mode ends to vaporize the condensed water in the condensation chamber, when the second operating time reaches the second preset time, that is, when the electric heating film stops working, the cooling fan is controlled to stop working to avoid continuous operation and waste of energy.

[0133] It can be seen that a cooling fan is arranged at the condensing chamber, and when the steam mode operation instruction is received, the cooling fan is controlled to start working, and when the second operation time of the steam mode operation ends reaches the second preset time, the cooling fan is controlled to stop working. The cooling fan is operated to prompt the water vapor in the condensing chamber to be quickly discharged from the steam oven, so as to prevent the water vapor from condensing into condensed water again in the condensing chamber, thereby reducing the amount of condensed water.

[0134] In some embodiments, see Fig.16 The steam oven provided in the embodiment of the present application mainly performs the following steps during operation:

[0135] S1601. The user selects a steam-related mode on the operation interface and sets a target temperature and cooking time.

[0136] When a user uses a steam oven for cooking, he needs to select a steam-related mode on the operation interface and set the target temperature and cooking time when the steam oven is running. It should be understood that the embodiment of the present application does not limit the way in which the user selects the steam-related mode.

[0137] As a feasible implementation method, the user can select a steam-related mode on the control panel of the steam oven and set the target temperature and cooking time. As another feasible implementation method, the user can select a steam-related mode on a terminal device connected to the steam oven and set the target temperature and cooking time. The terminal device sends the user-configured data to the steam oven to enable the steam oven to operate.

[0138] S1602, control the steam mode to start operation.

[0139] It should be understood that controlling the steam mode to start running can be to control the steam generating component to start generating high-temperature steam and to control the cooling fan to start running, and the embodiments of the present application do not impose any limitation on this.

[0140] S1603: Determine whether the cooking time is greater than a first preset time.

[0141] If so, execute S1604; if not, execute S1611.

[0142] S1604: When the first operating time reaches a first preset time, control the electric heating film to start heating.

[0143] The first operating time is the operating time of the steam mode.

[0144] When the running time of the steam mode reaches a first preset time, indicating that the amount of condensed water in the condensation chamber is large, the electric heating film is controlled to start heating to vaporize the condensed water in the condensation chamber to reduce the amount of condensed water.

[0145] As a feasible implementation method, controlling the electric heating film to start heating may specifically include: controlling the electric heating film to heat for a second preset time at intervals of a first preset time.

[0146] S1605: Determine whether the first operation time reaches the cooking time.

[0147] That is, it is determined whether the steam mode has ended. If so, S1606 is executed.

[0149] The end time after the steam mode operation ends is counted and is used as the second operation time.

[0150] S1607, obtaining the temperature inside the steaming and baking cavity, and determining whether the temperature inside the cavity is greater than a preset temperature threshold.

[0151] If so, execute S1613; if not, execute S1608.

[0152] S1608, controlling the electric heating film to heat for a second preset time at intervals of the first preset time.

[0153] S1611. In response to the steam mode operation ending, the second operation duration is counted.
