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, since high-temperature water vapor condenses into water droplets when encountering objects with lower temperatures, food residues and residual water will remain inside the steam-bake cavity after cooking is completed, and the user usually closes the door of the steam oven after taking away the cooked food.

[0004] As a result, the residual water inside the steam oven cannot evaporate naturally, and food residues and the like in the sealed and humid inner tank are prone to generate a large number of bacteria and odors, affecting the user experience of the steam oven. Summary of the invention

[0005] The embodiments of the present application provide a steam oven and a control method thereof, which are used to clean and / or dry the steam oven, thereby preventing a large amount of bacteria and odor from being generated in the steam oven, thereby improving the user experience.

[0006] In a first aspect, an embodiment of the present application provides a steam oven, which includes: an inner pot having a steaming and baking cavity; an air outlet arranged at the top of the inner pot; a condensation cavity, which is connected to the steaming and baking cavity through the air outlet and is used to store condensed water; a heating device, which is arranged in the inner pot and is used to heat the steaming and baking cavity; and an electric heating film, which is arranged at the bottom of the inner wall of the condensation cavity and is used to heat the condensed water in the condensation cavity; a controller, which is electrically connected to the electric heating film and the heating device; the controller is configured to: in response to receiving an instruction of a drying mode, control the heating device to start heating; after the heating device heats for a first preset time, control the electric heating film to start heating.

[0007] The steam oven provided in the embodiment of the present application controls the heating device to start heating after receiving the instruction of the drying mode, so as to evaporate the water droplets on the inner wall of the steaming and baking chamber, thereby achieving the purpose of drying the steaming and baking chamber. Then, after a first preset time, that is, after a certain amount of condensed water has accumulated in the condensing chamber, the electric heating film is controlled to start heating, so that the condensed water in the condensing chamber evaporates, thereby achieving the purpose of drying the condensing chamber.

[0008] That is to say, the steam oven provided in the embodiment of the present application can dry the steam-bake cavity and the condensing cavity after receiving the instruction of the drying mode, so as to avoid the problem that water accumulates inside the steam-bake cavity and the condensing cavity and causes bacteria to grow, thereby improving the user experience.

[0009] In combination with the first implementation method of the first aspect, the steam oven also includes: a temperature sensor, arranged in the inner pot, for detecting the cavity temperature of the steaming and baking cavity; after controlling the heating device to start heating, the controller is also configured to: obtain the cavity temperature detected by the temperature sensor; when the cavity temperature is above a first preset temperature, count the duration of the cavity temperature above the first preset temperature; in response to the duration reaching a second preset time, control the heating device to stop heating.

[0010] In combination with the second implementation of the first aspect, after controlling the heating device to stop heating, the controller is further configured to: count the heating time of the electric heating film; and control the electric heating film to stop heating in response to the heating time reaching a third preset time.

[0011] In combination with the third implementation method of the first aspect, after obtaining the cavity temperature detected by the temperature sensor, the controller is also configured to: when the cavity temperature is above a second preset temperature, control the heating device to perform intermittent operation; the second preset temperature is above the first preset temperature.

[0014] The steam oven provided in the embodiment of the present application controls the steam generator to generate a large amount of steam after receiving the instruction of the cleaning mode, so as to moisten the inner wall of the steaming and baking cavity, thereby facilitating the user to clean the residue or stains. Then, after a first preset time, that is, after a certain amount of condensed water has accumulated in the condensing cavity, the electric heating film is controlled to start heating, so that the condensed water in the condensing cavity evaporates, thereby achieving the purpose of drying the condensing cavity.

[0015] It can be seen that the steam oven provided in the embodiment of the present application can, after receiving the instruction of the cleaning mode, moisten the steam-bake cavity that needs to be cleaned by the user and dry the condensation cavity that does not need to be cleaned by the user. It is convenient for the user to clean the residue or stains on the inner wall of the steam-bake cavity, so that the steam oven will not generate a large amount of bacteria or odor after being stored for a long time, thereby improving the user experience.

[0016] In combination with the first implementation method of the third aspect, after counting the running time of the steam generator, the controller is also configured to: obtain the cleaning time corresponding to the cleaning mode; in response to the running time reaching the cleaning time, control the steam generator to stop working.

[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.

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 generator 104, a door switch sensor 105, a heating device 106 and 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 generator 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 connected to the inner pot 102; the water supply device 220 is connected to 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 generator 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 generator 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, the heating device 106 is disposed in the inner pot 102 to increase the temperature of the steaming and baking cavity to achieve the purpose of baking the food in the steaming and baking cavity.

[0058] As a feasible implementation, the heating device 106 may be a heating tube.

[0059] In some embodiments, Figure 3 As shown, the condensation chamber 107 is connected to the steam-bake chamber in the inner pot 102 through the air outlet 1021 at the top of the inner pot 102. When the steam oven 10 is in operation, the steam in the steam-bake chamber can enter the condensation chamber 107 through the air outlet 1021 at the top of the inner pot 102 and condense into condensed water. The condensation chamber 107 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.

[0060] In some embodiments, Figure 4 As shown, the steam oven 10 further includes: a display panel 111 , an operation panel 108 , a voice device 109 , a power supply 110 , and a controller 112 .

[0061] In some embodiments, the display panel 111 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.

[0062] 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 steam oven 10 through the operation panel 108 to adjust the mode, temperature, etc. of the steam oven 10.

[0063] 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!"

[0064] 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.

[0065] In some embodiments, Figure 5 As shown, the controller 112 is electrically connected to the steam generator 104, the door switch sensor 105, the heating device 106, the operation panel 108, the voice device 109, the power supply 110 and the display panel 111, and is used to generate an operation control signal according to the instruction operation code and the timing signal to instruct the steam oven 10 to execute the control instruction.

[0066] Exemplarily, the controller 112 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 112 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.

[0067] 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.

[0068] like Figure 6 As shown, when the steam oven is cooking food, the steam generator 104 will run to generate a large amount of high-temperature steam to heat the food. The high-temperature steam enters the condensation chamber 107 through the air outlet 1021 at the top of the inner pot 102 and condenses into condensed water. The condensation chamber 107 will store the condensed water. In order to prevent the condensed water in the condensation chamber 107 from dripping, as shown in FIG. Figure 6 As shown, the steam oven 10 provided in the embodiment of the present application further includes an electric heating film 71 .

[0069] In some embodiments, Figure 7 As shown, the electric heating film 71 can be arranged at the bottom of the inner wall of the condensation chamber 107 to heat the condensed water stored in the condensation chamber 107 .

[0070] 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.

[0071] As a possible implementation, see Figure 8 The electric heating film 71 includes a heating component 711 and a thermal protector 712 .

[0072] 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.

[0073] 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.

[0074] 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 higher than or equal to the preset disconnection temperature, it is in the off state, and the heating component 711 stops heating. In this way, the problem of the electric heating film 71 being continuously heated, which causes the temperature in the condensation chamber to be too high, can be avoided.

[0075] From the working principle of the steam oven, we can know that after cooking is completed, the high-temperature steam will condense into a large number of water droplets in the condensation chamber and the steaming and baking chamber, making the inside of the steam oven very humid and easy to generate a large number of bacteria.

[0076] Based on this, see Fig. 9 In the steam oven 10 provided in the embodiment of the present application, the controller is configured to perform the following steps:

[0077] S901 . In response to receiving a drying mode instruction, control a heating device to start heating.

[0078] After the user uses the steam oven for cooking, if there are a lot of water droplets inside the steam oven, the user can select the drying mode to dry the inside of the steam oven. It should be understood that the embodiment of the present application does not impose any limitation on the way in which the user selects the drying mode.

[0079] As a feasible implementation, the user can select the drying mode on the control panel of the steam oven. As another feasible implementation, the user can select the drying mode on a terminal device connected to the steam oven, and the terminal device sends the mode selected by the user to the steam oven to make the steam oven run.

[0080] After receiving the instruction of the drying mode, the steam oven controls the heating device to start heating to increase the temperature in the steaming and baking cavity, so that the water droplets on the inner wall of the steaming and baking cavity evaporate, thereby achieving the purpose of drying the steaming and baking cavity.

[0081] S902: After the heating device heats for a first preset time, control the electric heating film to start heating.

[0082] It should be understood that the first preset time is preset by the system, and in practical 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, and after the heating device heats for 10 minutes, the electric heating film is controlled to start heating.

[0083] It is understandable that since the user can directly observe the dryness condition inside the steaming and baking chamber, the user also determines the drying mode based on the internal condition of the steaming and baking chamber, and the condensing chamber is usually closed and arranged on the top of the inner tank, and the user cannot obtain the dryness condition inside the condensing chamber.

[0084] That is to say, when the user issues the drying mode, there may be no condensed water in the condensation chamber. If the electric heating film is controlled to start heating immediately after receiving the heating command, the electric heating film is easily burned when heated without condensed water, and a certain amount of energy is also wasted.

[0085] Therefore, in the steam oven provided in the embodiment of the present application, after the heating device heats for the first preset time and a certain amount of condensed water accumulates in the condensation chamber, the electric heating film is controlled to start heating. This can avoid the problem that the electric heating film is heated without condensed water, causing its own temperature to be too high and causing damage to the components, and can also save a certain amount of energy.

[0086] As a feasible implementation method, controlling the electric heating film to start heating may specifically include: controlling the electric heating film to perform intermittent heating.

[0087] Exemplarily, the electric heating film can be heated for 48 seconds per minute, that is, heated for 48 seconds per interval of 12 seconds.

[0088] Allowing the electric heating film to perform intermittent heating 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 frequent switching on and off of the thermal protector of the electric heating film, thereby extending the service life of the electric heating film.

[0089] It can be seen that the steam oven provided in the embodiment of the present application controls the heating device to start heating after receiving the instruction of the drying mode, so as to evaporate the water droplets on the inner wall of the steaming and baking chamber, thereby achieving the purpose of drying the steaming and baking chamber. Then, after the first preset time, that is, after a certain amount of condensed water has accumulated in the condensing chamber, the electric heating film is controlled to start heating, so that the condensed water in the condensing chamber evaporates, thereby achieving the purpose of drying the condensing chamber.

[0090] To sum up, the steam oven provided in the embodiment of the present application can dry the steam-bake chamber and the condensing chamber after receiving the instruction of the drying mode, thereby avoiding the problem of bacteria breeding caused by the accumulation of water inside the steam-bake chamber and the condensing chamber, thereby improving the user experience.

[0091] In some embodiments, the drying function of the steam oven is generally preset with a fixed time or requires the user to set the time, but the preset time is often not enough to dry the cavity of the steaming and baking cavity or the drying time is too long, resulting in a poor user experience.

[0092] Based on this, as a feasible implementation method, the steam oven provided in the embodiment of the present application also includes: a temperature sensor, which is arranged in the inner pot and is used to detect the cavity temperature of the steaming and baking cavity.

[0093] See also Fig.10 After S901, the controller of the steam oven provided in the embodiment of the present application is further configured to perform the following steps:

[0094] S1001. Obtain the cavity temperature detected by the temperature sensor.

[0095] The temperature sensor is arranged in the inner pot and is used to detect the cavity temperature of the steaming and baking cavity.

[0096] S1002: Determine whether the cavity temperature is above a first preset temperature.

[0097] It should be understood that the first preset temperature is pre-set by the system, and the preset temperature 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 preset temperature can be 130 degrees Celsius, and it is judged whether the cavity temperature is above 130 degrees Celsius.

[0098] If the cavity temperature is above the first preset temperature, execute S1003.

[0099] S1003: When the cavity temperature is above the first preset temperature, count the duration of the cavity temperature being above the preset temperature.

[0100] It is understandable that since the boiling temperature of water is around 100°C, the heating device continues to heat when there is a large amount of water in the steam-bake cavity. After the water evaporates, it will take away part of the heat, causing the cavity temperature of the steam-bake cavity to not continue to rise. The cavity temperature of the steam-bake cavity will not continue to rise until the amount of water is less.

[0101] Therefore, when the cavity temperature is above the first preset temperature, it is determined that the amount of water in the steaming and baking cavity is small. In order to further dry the steaming and baking cavity, the duration that the cavity temperature is above the first preset temperature is counted.

[0102] S1004: In response to the duration reaching a second preset time, control the heating device to stop heating.

[0103] It should be understood that the second preset time is pre-set by the system, and in practical applications, 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 second preset time can be 10 minutes, and when the duration reaches 10 minutes, the heating device is controlled to stop heating.

[0104] The duration of the cavity temperature being above the first preset temperature reaches a second preset time, and it is determined that the steaming and baking cavity has been completely dried. In order to avoid wasting energy by continuous heating by the heating device, the heating device is controlled to stop heating.

[0105] In some embodiments, when the temperature of the steam-bake cavity is above the first preset temperature, the heating device is controlled to continue heating in order to further dry the steam-bake cavity. However, the amount of water in the steam-bake cavity is small, and the continuous heating of the heating device will make the temperature in the steam-bake cavity too high, which will affect the service life of other components inside the steam oven.

[0106] Therefore, as a feasible implementation method, after S1001, the controller is further configured to: when the cavity temperature is above the second preset temperature, control the heating device to perform intermittent operation.

[0107] It should be understood that the second preset temperature is preset by the system, and the second preset temperature is higher than the first preset temperature. In practical applications, the second preset temperature 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 temperature can be 170 degrees Celsius, and when the cavity temperature is above 170 degrees Celsius, the heating device is controlled to perform intermittent work.

[0108] As a feasible implementation method, controlling the heating device to perform intermittent operation may be: controlling the heating device to heat for 30 seconds every 30 seconds.

[0109] The heating device is controlled to perform intermittent operation so that the cavity temperature of the steam-bake cavity is maintained at about the second preset temperature, which can prevent the cavity temperature of the steam-bake cavity from being too high and affecting the service life of other components inside the steam oven, thereby increasing the service life of the steam oven.

[0110] In some embodiments, the water in the steam-bake cavity evaporates into water vapor when the heating device is heated, and the water vapor enters the condensation cavity through the air outlet at the top of the inner pot and condenses into condensed water. That is, during the heating time of the heating device, there may be condensed water in the condensation cavity, and no new water vapor condenses into condensed water until the heating device stops heating.

[0111] As a possible implementation, see Fig.11 , after S1001, the controller is further configured to perform the following steps:

[0112] S1101, counting the heating time of the electric heating film.

[0113] S1102: In response to the heating time reaching a third preset time, controlling the electric heating film to stop heating.

[0114] It should be understood that the third preset time is preset by the system, and in actual applications, the third 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 third preset time can be 20 minutes, and when the heating time reaches 20 minutes, the electric heating film is controlled to stop heating.

[0115] After the heating device stops heating, since there may still be condensed water in the condensation chamber, the electric heating film is controlled to continue heating until the heating time of the electric heating film reaches the third preset time, and it is determined that the condensed water in the condensation chamber has been completely dried, and the electric heating film is controlled to stop heating.

[0116] It can be seen that after the heating device stops heating, the electric heating film is controlled to continue heating until the heating time of the electric heating film reaches the third preset time, and then the electric heating film is controlled to stop heating, which can ensure that the condensation chamber can be completely dried. It can prevent the condensed water in the closed condensation chamber from breeding a large number of bacteria and odors after long-term storage, affecting the user experience.

[0117] In some embodiments, see Fig.12 The steam oven provided in the embodiment of the present application performs the following steps after receiving the instruction of the drying mode:

[0118] S1201. Count the running time of the drying mode and obtain the cavity temperature of the steaming and baking cavity.

[0119] S1202: After the running time reaches a first preset time, control the electric heating film to start heating.

[0120] S1203, control the heating device to start heating.

[0121] S1204: Determine whether the cavity temperature is greater than a first preset temperature.

[0122] If yes, execute S1205; if no, return to execute S1203.

[0123] S1205: Determine whether the duration of the cavity temperature being greater than the first preset temperature exceeds a second preset time.

[0124] If so, execute S1206; if not, execute S1207.

[0125] S1206, controlling the heating device to stop heating, and controlling the electric heating film to stop heating at a third preset time after stopping heating.

[0126] S1207, controlling the heating device to perform intermittent heating so that the cavity temperature is maintained at about a second preset temperature.

[0127] The second preset temperature is higher than the first preset temperature.

[0128] The present application also provides a control method for a steam oven, which is applicable to the steam oven provided in the above embodiment. Fig.13 The control method provided in the embodiment of the present application includes the following steps:

[0129] S1301. In response to receiving a drying mode instruction, control a heating device to start heating.

[0130] S1302: After the heating device heats for a first preset time, control the electric heating film to start heating.

[0131] As a feasible implementation method, after S1301, the control method also includes the following steps: obtaining the cavity temperature detected by the temperature sensor; when the cavity temperature is above a first preset temperature, counting the duration of the cavity temperature above the first preset temperature; in response to the duration reaching a second preset time, controlling the heating device to stop heating.

[0132] As a feasible implementation, after S1301, the control method further includes the following steps: counting the heating time of the electric heating film; in response to the heating time reaching a third preset time, controlling the electric heating film to stop heating.

[0133] As a feasible implementation method, after obtaining the cavity temperature detected by the temperature sensor, the controller is also configured to: control the heating device to perform intermittent operation when the cavity temperature is above a second preset temperature; the second preset temperature is above the first preset temperature.

[0134] Since the steam oven is used to bake or steam food, it is inevitable that food residues or stains will contaminate the steam oven cavity during operation. When there are a lot of food residues or stains in the steam oven cavity, the user needs to clean the steam oven. And due to the drying function of the steam oven, most of the residues or stains will adhere to the inner wall of the steam oven cavity, making it difficult for the user to clean them.

[0135] Based on this, the present application embodiment provides a steam oven, see Fig.14 , the controller of the steam oven is configured to perform the following steps:

[0136] S1401 . In response to receiving a cleaning mode instruction, control the steam generator to start working.

[0137] When the user needs to clean the steam oven, he can send a cleaning mode command to the steam oven. When the controller of the steam oven receives the cleaning mode command, it controls the steam generator to start working. After the steam generator starts working, a large amount of steam is generated and diffused into the steam-baking cavity, so that the residue or stains on the inner wall of the steam-baking cavity can be soaked in water, making it easier for the user to clean the residue or stains.

[0138] It should be understood that the embodiment of the present application does not impose any limitation on the manner in which the user selects the cleaning mode. As a feasible implementation, the user can select the cleaning mode on the control panel of the steam oven and determine the cleaning time corresponding to the cleaning mode. As another feasible implementation, the user can select the cleaning mode on a terminal device connected to the steam oven and determine the cleaning time corresponding to the cleaning mode, and the terminal device sends the mode selected by the user and the corresponding time to the steam oven to enable the steam oven to operate.

[0139] S1402. Count the running time of the steam generator.

[0140] S1403: When the running time reaches a first preset time, control the electric heating film to start heating.

[0141] It should be understood that the first preset time is preset by the system, and in practical 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, and after the steam generator runs for 10 minutes, the electric heating film is controlled to start heating.

[0142] It is understandable that, since the steam-bake cavity has an opening, the user can directly clean the steam-bake cavity by opening the door, while the condensing cavity is usually closed and arranged on the top of the inner pot, and the user cannot clean the condensing cavity.

[0143] Therefore, after receiving the instruction of the cleaning mode, a steam generator is required to generate a large amount of steam for moistening the inside of the steam-bake cavity, while the condensing cavity needs to be heated by an electric heating film to make the condensing cavity dry.

[0144] At the same time, since there may be no condensed water in the condensation chamber when the user determines the cleaning mode, if the controller immediately controls the electric heating film to start heating after receiving the cleaning mode instruction, the electric heating film is easily burned when heated without condensed water, and a certain amount of energy is also wasted.

[0145] Therefore, in the steam oven provided in the embodiment of the present application, after the steam generator has been running for the first preset time and a certain amount of condensed water has accumulated in the condensation chamber, the electric heating film is controlled to start heating. This can avoid the problem that the electric heating film is heated without condensed water, causing its own temperature to be too high and causing damage to the components, and can also save a certain amount of energy.

[0146] As a feasible implementation method, controlling the electric heating film to start heating may specifically include: controlling the electric heating film to perform intermittent heating.

[0147] Exemplarily, the electric heating film can be heated for 48 seconds per minute, that is, heated for 48 seconds per interval of 12 seconds.

[0148] Allowing the electric heating film to perform intermittent heating 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 frequent switching on and off of the thermal protector of the electric heating film, thereby extending the service life of the electric heating film.

[0149] The steam oven provided in the embodiment of the present application controls the steam generator to generate a large amount of steam after receiving the instruction of the cleaning mode, so as to moisten the inner wall of the steaming and baking cavity, thereby facilitating the user to clean the residue or stains. Then, after a first preset time, that is, after a certain amount of condensed water has accumulated in the condensing cavity, the electric heating film is controlled to start heating, so that the condensed water in the condensing cavity evaporates, thereby achieving the purpose of drying the condensing cavity.

[0150] It can be seen that the steam oven provided in the embodiment of the present application can, after receiving the instruction of the cleaning mode, moisten the steam-bake cavity that needs to be cleaned by the user and dry the condensation cavity that does not need to be cleaned by the user. It is convenient for the user to clean the residue or stains on the inner wall of the steam-bake cavity, so that the steam oven will not generate a large amount of bacteria or odor after being stored for a long time, thereby improving the user experience.

[0151] In some embodiments, after receiving the instruction of the cleaning mode, the controller also needs to determine the cleaning time corresponding to the cleaning mode in order to control the operation of the steam generator.

[0152] As a possible implementation, see Fig.15 After S1402, the controller of the steam oven provided in the embodiment of the present application is further configured to perform the following steps:

[0153] S1501. Obtain the cleaning time corresponding to the cleaning mode.

[0154] It should be understood that the embodiment of the present application does not impose any limitation on the method for obtaining the cleaning time. As a feasible implementation method, the cleaning time is specified according to the dirtiness of the interior of the steaming and baking cavity when the user selects the cleaning mode.

[0155] As another feasible implementation, the cleaning time corresponds to the intensity of the cleaning mode selected by the user. For example, if the user selects "intensive cleaning", the corresponding cleaning time may be 20 minutes; if the user selects "medium cleaning", the corresponding cleaning time may be 15 minutes.

[0156] S1502: In response to the running time reaching the cleaning time, the steam generator is controlled to stop working.

[0157] When the running time of the steam generator reaches the cleaning time, it indicates that the humidity inside the steaming and baking chamber has reached the user's requirement, and the steam generator is controlled to stop working to avoid unnecessary operation and waste of energy.

[0158] In some embodiments, since a large amount of steam is generated when the steam generator is running, the steam can enter the condensation chamber through the air outlet at the top of the inner tank and condense into condensed water in the condensation chamber. When the steam generator stops running, a certain amount of condensed water will still exist in the condensation chamber, that is, when the running time reaches the cleaning time corresponding to the cleaning mode, condensed water will still exist in the condensation chamber.

[0159] As a feasible implementation, after S1502, the controller is further configured to perform the following steps: counting the heating time of the electric heating film; in response to the heating time reaching a second preset time, controlling the electric heating film to stop heating.

[0160] It should be understood that the second preset time is pre-set by the system, and in practical applications, 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 second preset time can be 20 minutes, and when the heating time reaches 20 minutes, the electric heating film is controlled to stop heating.

[0161] After the steam generator stops running, since there may still be condensed water in the condensation chamber, the electric heating film is controlled to continue heating until the heating time of the electric heating film reaches a second preset time, and it is determined that the condensed water in the condensation chamber has been completely dried, and the electric heating film is controlled to stop heating.

[0162] It can be seen that after the steam generator stops running, the electric heating film is controlled to continue heating until the heating time of the electric heating film reaches the third preset time, and then the electric heating film is controlled to stop heating, which can ensure that the condensation chamber can be completely dried. It can prevent the condensed water in the closed condensation chamber from breeding a large number of bacteria and odors after long-term storage, affecting the user experience.
