[0035] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which the same or similar elements or elements having the same or similar functions are denoted by the same or similar reference numerals throughout the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0036] With the improvement of people's living standards, the cooking of food not only stays in being edible, but also pursues healthy diet. Among many cooking methods, the steaming method is favored by people because of its delicious food effect and high nutritional value. Steam cooking is a healthy cooking method that can preserve the original flavor of food and avoid the loss of nutritional ingredients during cooking. Steam cooking has the following advantages: steam directly heats food, steaming and cooking are combined, no fire; steam condenses into distilled water, adjusts soup, long cooking without burning, long cooking without changing taste; no oil smoke, no name fire, no radiation, no environmental pollution; food tastes delicious, retains food nutrients, and causes little damage.

[0037] The present application provides a control method of a steam cooking appliance, which aims to solve the problem of the existing steam cooking method directly controlling the steam generating device to continuously generate a large amount of steam to cook food, wasting resources.

[0038] The embodiments of the present application and the control method, device and medium of the steam cooking appliance, and the electronic equipment will be described in detail below with reference to the accompanying drawings. Figures 1-8 and specific embodiments.

[0039] Figure 1 The structure schematic diagram of the steam cooking appliance of an embodiment of the present application. As shown in the figure, Figure 1 In an embodiment of the present application, the steam cooking appliance 100 can include a steamer 40, a steaming basket 50, a first steam assembly 20 and a second steam assembly 30, wherein the first steam assembly 20 is arranged corresponding to the steamer 40, and the second steam assembly 30 is arranged corresponding to the steaming basket 50.

[0040] The steamer 40 and the steaming basket 50 are both utensils for holding cooking food materials, and the steamer 40 and the steaming basket 50 for holding food materials can be arranged in the steam cooking appliance 100 respectively. The steamer 40 and the steaming basket 50 are arranged independently from each other, which increases the types and quantity of food materials cooked by the steam cooking appliance 100, and thus the diversity of food materials cooked by the steam cooking appliance 100 can be improved.

[0041] In this embodiment, the steamer 40 and the steaming basket 50 can be made of metal materials such as stainless steel, aluminum, etc., and a heat-conducting coating can be coated on the peripheral wall thereof to enhance the heat-conducting performance of the steamer 40 and the steaming basket 50, so as to accelerate the cooking rate.

[0042] In this embodiment, a plurality of through holes are arranged on the steaming basket 50, which are rectangular holes or arc-shaped holes. The through holes include a plurality of middle holes and a plurality of edge holes. The plurality of middle holes are located at the middle of the disc body, and the plurality of edge holes are located adjacent to the edge of the disc body and surround the outer periphery of the plurality of middle holes. Steam can pass through the plurality of through holes from the bottom of the tray to heat the food on the tray, thereby improving the heating efficiency of the steam cooking appliance 100.

[0043] The first steam assembly 20 and the second steam assembly 30 are used to generate high-temperature steam, which enters the steamer 40 and the steaming basket 50 to exchange heat with food materials, and thus the food is uniformly heated. The first steam assembly 20 for heating the steamer 40 and the second steam assembly 30 for heating the steaming basket 50 are arranged in the steam cooking appliance 100. The first steam assembly 20 acts on the steamer 40, and the second steam assembly 30 acts on the steaming basket 50. By arranging the steamer 40 and the steaming basket 50 independently from each other and their corresponding steam assemblies, the purpose of independently heating the steamer 40 and the steaming basket 50 can be achieved. When only the steamer 40 is needed to be used, the steamer 40 is heated alone, and when the steaming basket 50 is needed to be used, the steaming basket 50 is heated alone.

[0044] The steam cooking appliance 100 can further be provided with a water tank for storing purified water. Preferably, the number of water tanks is one, which is used to provide steam water to the first steam assembly 20 and the second steam assembly 30 respectively. The first steam assembly 20 and the second steam assembly 30 share one water tank, so that it is only necessary to observe whether the water in the water tank is sufficient for use, and only necessary to store a predetermined amount of purified water in the water tank, which has the advantage of being convenient to use. Preferably, the water tank is provided with a water level sensor, which, when sensing that the water level is too low, controls the indicator light to flash and alarms to remind the user to add water.

[0045] In this embodiment, a filter assembly is installed at the water inlet of the water tank, which is used to filter the water entering the water tank to ensure the purity of the water in the water tank. The filter assembly adopts a detachable structure, which is convenient for the user to replace regularly. The filter assembly can include a first-stage filter, a second-stage filter and a third-stage filter. The first-stage filter can be a PP cotton filter, which does not contain any chemical adhesive and is more hygienic and safe, and can effectively remove various particulate impurities in the filtered liquid. The second-stage filter can be a front-activated carbon filter, which can effectively remove organic matter, residual chlorine and other radioactive substances in water, and has the functions of decolorization and removal of odors. The first-stage and second-stage filters can be placed in the same cylinder. The third-stage filter can be a RO (Reverse Osmosis) membrane filter. The RO membrane filter can intercept various inorganic ions, colloidal substances and macromolecular solutes in water, thereby obtaining purified water.

[0046] Since the first steam assembly 20 and the second steam assembly 30 are independently arranged, when the first steam assembly 20 works, the steam generated by the first steam assembly 20 only cooks the food materials contained in the steamer 40, and when the second steam assembly 30 works, the steam generated by the second steam assembly 30 only cooks the food materials contained in the steaming cage 50. Therefore, when the steam cooking appliance 100 is used to cook food materials, the steamer 40 can be used to cook food materials, the steaming cage 50 can be used to cook food materials, and the steamer 40 and the steaming cage 50 can be used to cook food materials at the same time.

[0047] Since the steamer 40 and the steaming cage 50 can work independently, the user can select at least one of the steamer 40 and the steaming cage 50 to cook food materials according to needs, which not only meets the user's more use requirements, but also has the advantage of saving resources.

[0048] Figure 2 The flow chart of the control method of the steam cooking appliance of an embodiment of the present application is shown in FIG. 8. As shown in FIG. 8, the control method of the steam cooking appliance includes the following steps: Figure 2

[0049] Step S11, receiving a cooking instruction and determining a cooking mode according to the cooking instruction.

[0050] ​In one embodiment of the present application, the cooking instructions can include steamer cooking instructions and steaming basket cooking instructions, and the cooking mode can include steamer cooking mode and steaming basket cooking mode.

[0051] Specifically, when the received cooking instructions are steamer cooking instructions, the cooking mode of the steam cooking appliance 100 is determined as the steamer cooking mode, wherein the steamer cooking mode is a mode of controlling the first steam assembly 20 to work to cook the food material in the steamer 40. When the received cooking instructions are steaming basket cooking instructions, the cooking mode of the steam cooking appliance 100 is determined as the steaming basket cooking mode, wherein the steaming basket cooking mode is a mode of controlling the second steam assembly 30 to work to cook the food material in the steaming basket 50.

[0052] Step S12, if the cooking mode is the steamer cooking mode, the first steam assembly is controlled to cook the food material contained in the steamer.

[0053] Specifically, the control of the first steam assembly 20 can include: determining the cooking stage of the steam cooking appliance 100; and controlling the first steam assembly 20 according to the cooking stage.

[0054] In one embodiment of the present application, in the steamer cooking mode, the stage of heating the food material of the steam cooking appliance 100 can include a preheating stage, a heating stage, a water absorption stage and a braising stage. Different stages are set to cook different food materials according to the characteristics of the food material. The stages of heating the food material are different, and the working state of the first steam assembly 20 is different, and the amount of steam generated, the temperature, etc. are also different.

[0055] For example, when cooking rice, after completing the preheating stage of cooking the food material, the water absorption stage of the rice needs to be increased to improve the taste of the rice, and this stage can not be needed in other cooking methods, such as cooking porridge, cooking soup, etc.

[0056] As a feasible implementation, referring to Figure 1 , the first steam assembly 20 can include a first water pump 21 and a first heater 22. The first water pump 21 is used to pump water into the first heater 22, and the first heater 22 is used to vaporize the pumped water to cook the food material in the steamer 40. Wherein, the first heater 22 can be preferably a steam generator.

[0057] In this embodiment, the steam generator has a shell, a water storage cavity B is arranged in the shell, a combustion area A is arranged at the bottom of the water storage cavity B, and a flue gas discharge area C is arranged at the top of the water storage cavity B. The water storage cavity B and the flue gas discharge area C are separated by a partition. A water inlet and a steam outlet are arranged on the shell corresponding to the water storage cavity B. Wherein, the shell is a two-layer stainless steel structure, and the interlayer is filled with foamed polyurethane to improve its heat preservation performance.

[0058] The blast furnace combustion machine is arranged in the combustion zone A to combust and heat the water in the water storage zone B. In the water storage zone B, one end of the plurality of heat exchange pipes 20 is in communication with the combustion zone A at the bottom, and the other end is in communication with the flue gas discharge zone C at the top, which is directly in contact with the water in the water storage zone B. The flame and high-temperature flue gas generated in the combustion zone A can rise along the heat exchange pipes 20, and the heat exchange between the flame and high-temperature flue gas and the water in the water storage zone B can be achieved along the entire length of the heat exchange pipes 20. The water in the water storage zone B can quickly and sufficiently absorb the heat of the flame or high-temperature flue gas to generate steam, which is discharged from the steam outlet 14. The arrangement of the plurality of heat exchange pipes in communication between the combustion zone and the flue gas discharge zone in the water storage zone enables the steam generator to have the advantages of large heat exchange area and high heat exchange efficiency.

[0059] As an example, as shown in the preheating phase, the first steam assembly 20 is controlled according to the cooking phase, which can include: Figure 3

[0060] Step S21, in the preheating phase, controlling the first water pump to pump a first amount of water into the first heater.

[0061] Specifically, the first water pump 21 is started to add a first amount of water to the first heater 22, which can prevent the first heater 22 from being directly heated and cause the first heater 22 to dry out. The first amount of water pumped by the first water pump 21 can be a fixed value, such as 5-10g, or can be calculated according to the volume of the connecting pipe circuit from the water tank to the first heater 22.

[0062] Step S22, controlling the first heater to work, and when the temperature of the first heater is greater than a first temperature, controlling the first water pump to pump water to the first heater at a first flow rate.

[0063] Specifically, the first heater 22 is started to heat the internal water and vaporize the first amount of water. Since the first heater 22 no longer continues to add water, and it continues to be heated, the temperature of the first heater 22 will continue to rise, and when the temperature of the first heater 22 reaches the first temperature, to prevent the first heater 22 from being in a dry state, the first water pump 21 is started again and pumps water to the first heater 22 at a first flow rate, so that the first heater 22 continues to generate steam. The first temperature is the temperature of the first heater 22 when the first amount of water pumped is completely vaporized.

[0064] Step S23, when the temperature of the first heater is greater than a second temperature, controlling the first heater to be closed, and controlling the first water pump to pump water to the first heater at a second flow rate, wherein the second temperature is greater than the first temperature, and the second flow rate is less than the first flow rate.

[0065] ​While the first water pump 21 pumps water to the first heater 22 at the first flow rate, the temperature of the first heater 22, which is continuously in the heating state, continues to rise, and the amount of water pumped at the first flow rate is completely vaporized by the first heater 22.

[0066] To prevent the first heater 22 from being in a dry heating state, when the temperature of the first heater 22 is greater than a second temperature, which is greater than the first temperature, the first heater 22 is turned off, and the first water pump 21 is controlled to pump water to the first heater 22 at a second flow rate, which is less than the first flow rate. At this time, since the first heater 22 has stopped working, to prevent the temperature of the first heater 22 from falling too fast and too little steam being generated, the first water pump 21 can be controlled to pump water to the first heater 22 at the second flow rate, which is less than the first flow rate.

[0067] Optionally, when the first water pump 21 pumps the first amount of water, the flow rate of the pumped water can be the first flow rate, so as to save the water pumping time.

[0068] Step S24: When the temperature of the first heater is less than a third temperature, which is less than the second temperature, the first heater is controlled to work, and the process returns to the step of controlling the first water pump to pump water to the first heater at the first flow rate.

[0069] Since the first heater 22 is turned off and the first water pump 21 continues to pump water to the first heater 22 at the second flow rate, the temperature of the first heater 22 slowly falls.

[0070] When the temperature of the first heater 22 is less than a third temperature, which is less than the second temperature, the first heater 22 can be turned on again, and step S21 is performed. In the preheating phase, the above steps S21-S24 can be cyclically repeated, so that the first heater 22 continuously generates steam to preheat the food materials in the steamer 40.

[0071] Step S25: When the preheating phase time reaches a preset time, the preheating phase ends.

[0072] It should be noted that the first flow rate and the second flow rate can be optimized according to the specific cooking food materials. For example, when cooking rice, the first flow rate can be 7-10 ml / s, and the second flow rate can be 6-8 ml / s.

[0073] As an example, as shown in FIG. 6, in the heating phase, the first steam assembly 20 is controlled according to the cooking phase, and the control method can further include: Figure 4

[0074] Step S31: In the heating phase, the first heater is controlled to work.

[0075] ​Specifically, a large amount of steam is required to cook the food in the heating stage, at which time the first heater 22 can be turned on to vaporize the water in the first heater 22 to generate steam.

[0076] In step S32, when the temperature of the first heater is greater than the first temperature, the first water pump is controlled to pump water to the first heater at a third flow rate.

[0077] Specifically, when the temperature of the first heater 22 is raised to the first temperature, it indicates that the water in the first heater 22 is completely vaporized, and the first heater 22 is prevented from being dry.

[0078] When the temperature of the first heater 22 is greater than the first temperature, the first water pump 21 is again controlled to be turned on and pump water to the first heater 22 at a third flow rate, so that the first heater 22 continues to generate steam.

[0079] In step S33, when the temperature of the first heater is greater than a fourth temperature, the first heater is controlled to be turned off, and the first water pump is controlled to pump water to the first heater at a fourth flow rate, wherein the fourth temperature is greater than the first temperature, and the fourth flow rate is less than the third flow rate.

[0080] Specifically, the first heater 22 is turned on, and the first heater 22 continues to work, and the temperature of the first heater 22 will be higher and higher, and the water pumped in at the third flow rate will be completely vaporized.

[0081] Therefore, when the temperature of the first heater 22 is greater than the fourth temperature, wherein the fourth temperature is greater than the first temperature, the first heater 22 needs to be temporarily turned off, and the first water pump 21 is controlled to pump water to the first heater 22 at a fourth flow rate, so that the first heater 22 continues to generate steam, wherein the fourth flow rate is less than the third flow rate.

[0082] In step S34, when the temperature of the first heater is less than a fifth temperature, the first heater is controlled to work, and returns to the step of controlling the first water pump to pump water to the first heater at the third flow rate, wherein the fifth temperature is less than the fourth temperature.

[0083] Specifically, the first heater 22 is turned off, and the first heater 22 stops working, and the first water pump 21 pumps water at the fourth flow rate, and the temperature of the first heater 22 will gradually decrease.

[0084] In order to make the first heater 22 continue to generate steam, the first heater 22 can be turned on again when the temperature of the first heater 22 is less than the fifth temperature, and step S32 is performed.

[0085] In the heating stage, the above steps S32-S34 can be cyclically repeated to make the first heater 22 continue to generate steam to heat the food in the steamer 40.

[0086] It should be noted that the third flow rate and the fourth flow rate can be adjusted according to specific cooking ingredients. For example, when cooking rice, the third flow rate can be 6-10 ml / s, and the second flow rate can be 5-8 ml / s.

[0087] As an example, as shown in Figure 5 The water absorption stage is between the preheating stage and the heating stage.

[0088] According to the control of the first steam assembly 20 according to the cooking stage, the first heater 22 and the first water pump 21 can be turned off in sequence and for a first time during the water absorption stage.

[0089] Specifically, taking cooking rice as an example, under the condition of heating and sufficient water, the starch molecular structure will change, and part of the chemical bonds will be opened due to heating, changing from a tight state to a loose state. With sufficient water, water molecules are more likely to enter the loose chemical structure, which is also beneficial to our digestion and absorption. Therefore, controlling the first heater 22 and the first water pump 21 to stop working for a first time allows the food in the steamer 40 to have time to absorb water, enhancing the taste and facilitating subsequent more effective heating.

[0090] As an example, as shown in Figure 5 The braising stage is after the heating stage.

[0091] According to the control of the first steam assembly 20 according to the cooking stage, the first water pump 21 and the first heater 22 can be turned off in sequence and for a second time during the braising stage.

[0092] Specifically, taking cooking rice as an example, if the rice cooked in the high-steam heating stage is immediately served, it will often be found to be very sticky and to stick to the spoon and the pot, and the taste is also poor. Braising the rice cooked in the high-steam heating stage for a while can allow water to effectively enter between the rice grains, so that each rice grain absorbs water and becomes more full and the taste becomes better, and there is no stickiness. Therefore, after the food in the steamer 40 has gone through the high-steam heating stage, there is a large amount of steam remaining in the steamer 40. Controlling the first water pump 21 and the first heater 22 to stop working allows the remaining steam in the steamer 40 to be used for heat preservation for a second time, enhancing the taste of the food.

[0093] Figure 5 The flowchart of the control method of the steam cooking appliance in the steamer cooking mode according to an embodiment of the present application is described below in combination with Figure 1 and 5 The control method of the steam cooking appliance 100 in the steamer cooking mode according to an embodiment of the present application is described below in combination with a specific embodiment:

[0094] When the food material inside the steamer 40 is rice, and the rice is being cooked, the steam cooking appliance 100 receives the steamer cooking instruction, and the steam cooking appliance 100 enters the steamer cooking mode.

[0095] At the beginning of cooking, the first water pump 21 is turned on to pump the first amount of water into the first heater 22, and then the first heater 22 is turned on to generate steam to preheat the food material inside the steamer 40, and the temperature of the first heater 22 is monitored.

[0096] Figure 5 The flow chart of the control method of the steam cooking appliance in the steamer cooking mode of a specific embodiment of the present application. Referring to Figure 5 At the beginning of cooking, the first water pump 21 is turned on to pump the first amount of water into the first heater 22, and then the first heater 22 is turned on to generate steam to preheat the food material inside the steamer 40, and the temperature of the first heater 22 is monitored.

[0097] When the temperature of the first heater 22 reaches T1 (the first temperature), it indicates that the amount of water in the first heater 22 is completely evaporated and burned dry, the first water pump 21 is turned on, and the first water pump 21 is controlled to pump water into the first heater 22 at a rate of P1 (the first flow rate).

[0098] As the temperature of the first heater 22 continues to rise, the water pumped into the first heater 22 at the rate of P1 will be completely evaporated, so when the temperature of the first heater 22 is greater than T2 (the second temperature), the first heater 22 is turned off, and the first water pump 21 is controlled to pump water into the first heater 22 at a rate of P2 (the second flow rate).

[0099] When the temperature of the first heater 22 is less than T3 (the third temperature), the first heater 22 is turned on again, and the first water pump 21 is controlled to pump water into the first heater 22 at a rate of P1, and the cycle continues until the preheating time ends.

[0100] When the water absorption stage is entered, the first heater 22 and the first water pump 21 are controlled to stop working, and a first time is maintained to allow the food material to absorb sufficient moisture.

[0101] When entering the heating stage, the first heater 22 is turned on, and the temperature of the first heater 22 gradually increases. When the temperature of the first heater 22 is greater than T1, it indicates that the water in the first heater 22 is completely vaporized and burned out. The first water pump 21 is turned on to pump water into the first heater 22 at a rate of P3 (third flow rate). When the water pumped at the rate of P3 is evaporated, that is, when the temperature of the first heater 22 is greater than T4 (fourth temperature), the first heater 22 is turned off, and the first water pump 21 is controlled to pump water into the first heater 22 at a rate of P4 (fourth flow rate). When the temperature of the first heater 22 is less than T5 (fifth temperature), the first heater 22 is turned on again to continuously generate steam. This cycle continues until the heating stage ends.

[0102] When entering the holding stage, the first water pump 21 and the first heater 22 are turned off, and the residual steam in the steamer 40 is used for holding, and the holding continues for a second time. When the second time ends, the cooking ends.

[0103] It should be noted that, Figure 5 The values of A, B, C, and D can be set according to the types of cooking materials to achieve the best taste of the food.

[0104] In this embodiment, the control method of the steam cooking appliance provided by the embodiment of the present application provides multiple cooking stages in the steamer cooking mode. In different cooking stages, the water pumped by the first water pump 21 and the heating time of the first heater 22 are different, and the amount of steam generated is also different. According to the types of food materials, corresponding stage combinations are provided to improve the taste of food materials and improve the user experience.

[0105] In step S13, if the cooking mode is the steamer basket cooking mode, the second steam assembly is controlled to cook the food materials placed in the steamer basket.

[0106] As a feasible implementation manner, referring to Figure 6 The steam cooking appliance 100 can further include a hot plate 60 arranged corresponding to the steamer basket 50, and the second steam assembly 30 can include a second water pump 31 and a second heater 32. The second water pump 31 is used to pump water to the second heater 32, and the second heater 32 is used to vaporize the water pumped by the second water pump 31 into the hot plate 60.

[0107] In this embodiment, the heat disc 60 is provided with a plurality of one-way communication vaporization cavities, which can be an inner recessed multi-layer stepped structure. The water vaporized in the heat disc 60 flows along the one-way communication vaporization cavities one by one. The water that is not vaporized stays in the vaporization cavities. The vaporization cavities are an inner recessed multi-layer stepped structure, which increases the vaporization area of the heat disc 60, so that the water staying in the vaporization cavities has more contact area with the inner surface of the heat disc 60. After a few seconds, the water staying in the vaporization cavities can be vaporized, so as to improve the heating efficiency of the heat disc 60 and the water vaporization rate.

[0108] As an example, as shown in FIG. 6, in the steamer cooking mode, the control of the second steam assembly 20 can include: Figure 7

[0109] In step S131, the second water pump is controlled to pump the second water amount into the heat disc, and the second heater is controlled to work.

[0110] Specifically, the second water pump 31 is started. After the second water pump 31 pumps the second water amount into the heat disc 60, the second heater 32 is started to heat the heat disc 60, so that the water in the heat disc 60 is vaporized, and the steam is discharged from the vaporization cavity of the heat disc 60 to cook the food in the steamer 50.

[0111] It should be noted that since there can be water in the heat disc 60 when cooking starts, the first time the second water amount is pumped into the heat disc 60, the water amount in the heat disc 60 can be too much to cause water overflow. Therefore, the fourth water amount can be added when the water is first added, and the fourth water amount is less than the second water amount. Since whether to pump water into the heat disc 60 is determined by judging whether the heat disc 60 is dry, after the first time the water is pumped, the second water amount can be directly pumped into the heat disc 60 in the subsequent water pumping process.

[0112] In this embodiment, the second water amount can be a fixed value, such as 50-100g, or can be calculated according to the area of the heat disc 60, wherein the bottom area of the heat disc 60 is S, the optimized liquid level height is h, and the second water amount is calculated according to the bottom area of the heat disc 60 and the optimized liquid level height.

[0113] In step S132, when the temperature of the second heater is greater than the first temperature, and the remaining cooking time is greater than the preset time, the second water pump is controlled to pump the second water amount into the heat disc.

[0114] ​In this embodiment, when the water in the hot plate 60 is sufficient, the temperature of the hot plate 60 is maintained at a constant temperature, and when the water in the hot plate 60 is evaporated, the temperature of the hot plate 60 continues to rise. When the temperature of the second heater 32 rises to the first temperature and the remaining cooking time is greater than the preset time, it is determined that the internal water of the hot plate 60 is in a dry burning state, the heating of the hot plate 60 is stopped, the second water pump 31 is started to pump the second amount of water into the hot plate 60 again, and the second heater 32 is started to heat the hot plate 60 again. Thus, the cycle is repeated.

[0115] In step S133, when the temperature of the second heater is greater than the first temperature and the remaining cooking time is less than or equal to the preset time, the second heater is controlled to be turned off, and the second water pump is controlled to pump a third amount of water into the hot plate, wherein the third amount of water is less than the second amount of water.

[0116] Since the remaining cooking time is less than or equal to the preset time, when the temperature of the second heater 32 is greater than the first temperature, the second amount of water is pumped into the hot plate 60 again, and when the cooking time ends, there is some water in the hot plate 60.

[0117] To ensure that there is no large amount of water in the hot plate 60 that has not been evaporated at the end of cooking, and to prevent the hot plate 60 from being dry, when the temperature of the second heater 32 is greater than the first temperature, the second heater 32 is turned off, the second water pump 31 is started, and a third amount of water is pumped into the hot plate 60, wherein the third amount of water is less than the second amount of water. In this embodiment, the third amount of water can be Wherein X is the second amount of water, t is the preset time, and t1 is the remaining cooking time.

[0118] Figure 8 The flowchart of the control method of the steam cooking appliance in the steamer cooking mode according to an embodiment of the present application is described below in conjunction with Figure 8 The control method of the steam cooking appliance in the steamer cooking mode according to an embodiment of the present application is described below in conjunction with

[0119] When the steam cooking appliance 100 receives the steamer cooking instruction, the steam cooking appliance 100 enters the steamer cooking mode. After the second water pump 31 is started to pump the second amount of water into the hot plate 60, the second heater 32 is started to heat the hot plate 60 and vaporize the water in the hot plate 60.

[0120] When the temperature of the second heater 32 rises to the first temperature and the remaining cooking time is greater than the preset time, it can be determined that the hot plate 60 is dry-burning due to lack of water. At this time, heating of the hot plate 60 is stopped, and the second water pump 31 is turned on to pump a second amount of water into the hot plate 60 again. The second heater 32 is then turned on again to heat the hot plate 60, and this cycle is repeated. When the temperature of the second heater 32 is greater than the first temperature and the remaining cooking time is less than or equal to the preset time, the second heater 32 is turned off, the second water pump 31 is turned on, and a third amount of water is pumped into the hot plate 60 to ensure that when cooking is finished, there is no large amount of water left on the surface of the hot plate 60 that has not evaporated, and the hot plate 60 does not dry-burn.

[0121] In this embodiment, water is added based on the remaining water in the hot plate 60 during the first addition, effectively preventing the water pumped in from overflowing the hot plate 60. When cooking is almost over, water is added based on the remaining cooking time, effectively preventing a large amount of residual water from appearing on the surface of the hot plate 60. This has the advantage of using water efficiently. In the steamer cooking mode, intermittent water addition and heating can also prevent the steam from condensing into water and falling down when there is too much steam, thus affecting the taste of the food.

[0122] It should be noted that, in the embodiments of the present invention, the temperatures of the first heater 22 and the second heater 32 can be detected using temperature sensors.

[0123] In summary, the control method provided by the embodiments of the present invention offers a steamer cooking mode and a steamer cooking mode, which can control steam cooking appliances 40 and 50 with independent steam systems, and can independently cook the food stored in the steamer 40 and steamer 50, which has the advantage of saving resources. In the steamer cooking mode, different cooking stage combinations can be selected according to the food, which can enhance the taste of the food. In the steamer cooking mode, intermittent water heating can also prevent the steam from condensing into water and falling down when there is too much steam, thus affecting the taste of the food.

[0124] The present invention also proposes a control device for a steam cooking appliance. Figure 1 This is a schematic diagram of the structure of a steam cooking appliance according to an embodiment of the present invention.

[0125] like Figure 1 As shown, the steam cooking appliance 100 includes a steamer 40, a steam basket 50, a first steam component 20 and a second steam component 30. The first steam component 20 is set to correspond to the steamer 40, and the second steam component 30 is set to correspond to the steam basket 50.

[0126] The steamer 40 and the steaming basket 50 are both utensils for containing cooking food. The steamer 40 and the steaming basket 50 can be arranged in the steam cooking utensil 100 for containing food, and the steamer 40 and the steaming basket 50 are arranged independently of each other, which increases the types and quantity of food cooked by the steam cooking utensil 100, and thus improves the diversity of food cooked by the steam cooking utensil 100.

[0127] In this embodiment, the steamer 40 and the steaming basket 50 can be made of metal, such as stainless steel, aluminum, etc., and can be coated with a heat-conducting coating on the peripheral wall to enhance the heat-conducting performance of the steamer 40 and the steaming basket 50, thereby accelerating the cooking rate.

[0128] In this embodiment, the steaming basket 50 is provided with a plurality of through holes, which are rectangular holes or arc-shaped holes. The through holes include a plurality of middle holes and a plurality of edge holes. The plurality of middle holes are located in the middle of the disc body, and the plurality of edge holes are located adjacent to the edge of the disc body and surround the outer periphery of the plurality of middle holes. Steam can pass through the plurality of through holes from the bottom of the tray to heat the food on the tray, thereby improving the heating efficiency of the steam cooking utensil 100.

[0129] The steam cooking utensil 100 can further be provided with a first steam assembly 20 for heating the steamer 40 and a second steam assembly 30 for heating the steaming basket 50. The first steam assembly 20 and the second steam assembly 30 are used to generate high-temperature steam, which enters the steamer 40 and the steaming basket 50 to exchange heat with the food, thereby uniformly heating the food. The first steam assembly 20 acts on the steamer 40, and the second steam assembly 30 acts on the steaming basket 50. By arranging the steamer 40 and the steaming basket 50 independently of each other and their corresponding steam assemblies, the purpose of independently heating the steamer 40 and the steaming basket 50 can be achieved. When only the steamer 40 is needed, the steamer 40 is heated alone, and when the steaming basket 50 is needed, the steaming basket 50 is heated alone.

[0130] The steam cooking utensil 100 can further be provided with a water tank for storing clean water. Preferably, the number of water tanks is one, which is used to provide steam water for the first steam assembly 20 and the second steam assembly 30. The first steam assembly 20 and the second steam assembly 30 share one water tank, and only one water tank needs to be observed to determine whether the water is sufficient for use, and only one water tank needs to be reserved with a predetermined amount of clean water, which has the advantage of convenient use. Preferably, the water tank is provided with a water level sensor. When the water level sensor senses that the water level is too low, the controller controls the indicator light to flash and alarms to remind the user to add water.

[0131] In this embodiment, a filter assembly is installed at the water inlet of the water tank to filter the water entering the water tank, so as to ensure the purity of the water in the water tank. The filter assembly has a detachable structure, which is convenient for users to replace regularly. The filter assembly can include a first-stage filter core, a second-stage filter core and a third-stage filter core. The first-stage filter core can be a PP cotton filter core, which does not contain any chemical adhesive and is more hygienic and safe, and can effectively remove various particulate impurities in the filtered liquid. The second-stage filter core can be a front-arranged activated carbon filter core, which can effectively remove organic matter, residual chlorine and other radioactive substances in water, and has the functions of decolorization and removal of peculiar smell. The first-stage and second-stage filter cores can be placed in the same cylinder, and the third-stage filter core can be an RO (Reverse Osmosis) membrane filter core. The RO membrane filter core can intercept various inorganic ions, colloidal substances and macromolecular solutes in water, so as to obtain purified water.

[0132] Due to the arrangement of the first steam assembly 20 and the second steam assembly 30 which are independent of each other, when the first steam assembly 20 works, the steam generated by the first steam assembly 20 only cooks the food materials contained in the steamer 40, and when the second steam assembly 30 works, the steam generated by the second steam assembly 30 only cooks the food materials contained in the steaming cage 50. Therefore, when the user cooks food materials by using the steam cooking appliance 100, the user can only use the steamer 40 to cook food materials, can only use the steaming cage 50 to cook food materials, or can use the steamer 40 and the steaming cage 50 simultaneously to cook food materials.

[0133] Due to the fact that the steamer 40 and the steaming cage 50 can work independently, the user can select at least one of the steamer 40 and the steaming cage 50 to cook food materials according to needs, which not only meets the user's more use requirements, but also has the advantage of saving resources.

[0134] Referring to Figure 1 , the control device 10 of the steam cooking appliance includes a receiving module 11, a determining module 12 and a control module 13

[0135] The receiving module 11 is configured to receive a cooking instruction; the determining module 12 is configured to determine a cooking mode according to the cooking instruction; and the control module 13 is configured to control the first steam assembly 20 to cook the food materials contained in the steamer 40 when the cooking mode is the steamer cooking mode, and control the second steam assembly 30 to cook the food materials contained on the steaming cage 50 when the cooking mode is the steaming cage cooking mode.

[0136] In an embodiment of the present application, the cooking instruction can include a steamer cooking instruction and a steaming cage cooking instruction, and the cooking mode can include a steamer cooking mode and a steaming cage cooking mode.

[0137] Specifically, when the cooking instruction received by the receiving module 11 is a steaming pot cooking instruction, the determining module 12 determines that the steam cooking appliance 100 enters a steaming pot cooking mode, wherein the steaming pot cooking mode is a mode of controlling the first steam assembly 20 to work to cook the food material in the steaming pot 40. When the cooking instruction received by the receiving module 11 is a steaming basket cooking instruction, the determining module 12 determines that the steam cooking appliance 100 enters a steaming basket cooking mode, wherein the steaming basket cooking mode is a mode of controlling the second steam assembly 30 to work to cook the food material in the steaming basket 50.

[0138] In an embodiment of the present application, in the steaming pot cooking mode, the stage of heating the food material can include a preheating stage, a heating stage, a water absorbing stage, and a simmering stage, wherein the water absorbing stage is between the preheating stage and the heating stage, and the simmering stage is after the heating stage. Different stages are set to cook different food materials according to the characteristics of the food material to be cooked by selecting different stage combinations. The working state of the first steam assembly 20 is different when the stage of heating the food material is different, and the amount and temperature of the steam generated by the first steam assembly 20 are also different.

[0139] For example, when cooking rice, the water absorbing stage of the rice needs to be increased after the preheating stage of cooking the food material is completed to improve the taste of the rice, but this stage may not be needed in other cooking methods, such as cooking porridge and cooking soup.

[0140] As a feasible implementation, the first steam assembly 20 can include a first water pump 21 and a first heater 22.

[0141] In the preheating stage, the first water pump 21 is controlled to pump the first amount of water into the first heater 22, which can prevent the first heater 22 from being directly heated and causing dry burning of the first heater 22. The first heater 22 is started to heat the internal amount of water and vaporize the first amount of water.

[0142] Since the first heater 22 no longer continues to add water, and it continues to be heated, the temperature of the first heater 22 will continue to rise, and when the temperature of the first heater 22 reaches the first temperature, to prevent the first heater 22 from being in a dry burning state, the first water pump 21 can be started again and pump water into the first heater 22 at the first flow rate, so that the first heater 22 continues to generate steam. The first temperature is the temperature of the first heater 22 when the first amount of water pumped in is completely vaporized.

[0143] Although the first water pump 21 pumps water into the first heater 22 at the first flow rate, the temperature of the first heater 22, which is continuously in a heated state, will continue to rise, and the amount of water pumped in at the first flow rate will be completely vaporized by the first heater 22.

[0144] To prevent the first heater 22 from being in a dry heating state, when the temperature of the first heater 22 is greater than a second temperature, where the second temperature is greater than the first temperature, the first heater 22 can be turned off, and the first water pump 21 can be controlled to pump water to the first heater 22 at a second flow rate, where the second flow rate is less than the first flow rate. At this time, since the first heater 22 has stopped working, to prevent the temperature of the first heater 22 from dropping too fast and generating too little steam, the first water pump 21 can be controlled to pump water to the first heater 22 at the second flow rate, which is less than the first flow rate.

[0145] Since the first heater 22 is turned off, the first heater 22 stops working, and the first water pump 21 continues to pump water to the first heater 22 at the second flow rate, the temperature of the first heater 22 will slowly drop.

[0146] When the temperature of the first heater 22 is less than a third temperature, where the third temperature is less than the second temperature, the first heater 22 can be turned on again, and step S21 can be performed. In the preheating stage, the above steps S21-S24 can be cyclically repeated to continuously generate steam in the first heater 22 to preheat the food materials in the steamer 40.

[0147] In the heating stage, a large amount of steam needs to be generated to cook the food materials, at this time, the first heater 22 can be turned on to evaporate the amount of water in the first heater 22 to generate steam.

[0148] Specifically, when the temperature of the first heater 22 rises to the first temperature, it indicates that the amount of water in the first heater 22 is completely vaporized. To prevent the first heater 22 from being in a dry heating state, when the temperature of the first heater 22 is greater than the first temperature, the first water pump 21 can be controlled to be turned on again, and water can be pumped to the first heater 22 at a third flow rate to continuously generate steam in the first heater 22.

[0149] Specifically, when the first heater 22 is turned on, the first heater 22 continues to work, and its temperature will continue to rise, and the amount of water pumped at the third flow rate will be completely evaporated.

[0150] Therefore, when the temperature of the first heater 22 is greater than a fourth temperature, where the fourth temperature is greater than the first temperature, the first heater 22 needs to be temporarily turned off, and the first water pump 21 can be controlled to pump water to the first heater 22 at a fourth flow rate to continuously generate steam in the first heater 22, where the fourth flow rate is less than the third flow rate.

[0151] Specifically, when the first heater 22 is turned off, the first heater 22 stops working, and the first water pump 21 continues to pump water at the fourth flow rate, the temperature of the first heater 22 will gradually drop.

[0152] To make the first heater 22 continuously generate steam, the first heater 22 can be turned on again when the temperature of the first heater 22 is less than the fifth temperature, and step S32 is performed. In the heating stage, the above steps S32-S34 can be cyclically repeated to continuously generate steam by the first heater 22 to heat the food in the steamer 40.

[0153] In the water absorption stage, taking cooking rice as an example, the rice will cause the starch molecular structure to change under the condition of heating and sufficient moisture, and part of the chemical bonds will be opened due to heating, changing from a tight state to a loose state. With sufficient moisture, water molecules are more likely to enter the loose chemical structure, which is also beneficial to our digestion and absorption. Therefore, controlling the first heater 22 and the first water pump 21 to stop working and continuously for a first time can make the food in the steamer 40 have a certain time to absorb water, enhance the taste, and also facilitate subsequent more effective heating.

[0154] In the braising stage, taking cooking rice as an example, if the rice cooked by the high-steam heating stage is immediately served, it will be found that the rice is very sticky and sticks to the spoon and the pot, and the taste is relatively poor. If the rice cooked by the high-steam heating stage is braised for a while, the water can effectively enter between the rice grains, so that each rice grain absorbs water and becomes more full, the taste becomes better, and the sticking condition does not occur. Therefore, after the food in the steamer 40 experiences the high-steam heating stage, a large amount of steam remains in the steamer 40. Therefore, in the braising stage, the first water pump 21 and the first heater 22 can be controlled to stop working, the residual steam in the steamer 40 is used for heat preservation, and the heat preservation is continuously performed for a second time to enhance the taste of the food.

[0155] In this embodiment, the control method of the steam cooking appliance provided by the embodiment of the present application provides a plurality of cooking stages in the steamer cooking mode, and the amount of water pumped by the first water pump 21 and the heating time of the first heater 22 are different in different cooking stages, the amount of generated steam is also different, and corresponding stage combinations are provided according to the types of food to improve the taste of the food and improve the experience of the user.

[0156] In an embodiment of the present application, in the steamer cooking mode, the food placed in the steamer 50 is cooked.

[0157] As a feasible implementation manner, referring to Figure 6 The steam cooking appliance 100 can further include a hot plate 60 arranged corresponding to the steamer 50, and the second steam assembly 30 can include a second water pump 31 and a second heater 32. The second water pump 31 is used to pump water to the second heater 32, and the second heater 32 is used to steam the amount of water pumped by the second water pump 31 into the hot plate 60.

[0158] In this embodiment, the heat plate 60 is provided with a plurality of one-way communication vaporization cavities, which can be an inner recess multi-layer stepped structure. The water vaporized in the heat plate 60 flows along the one-way communication vaporization cavities one by one. The water that has not been vaporized stays in the vaporization cavities. The vaporization cavities are an inner recess multi-layer stepped structure, which increases the vaporization area of the heat plate 60, so that the water staying in the vaporization cavities has more contact area with the inner surface of the heat plate 60, and the water staying in the vaporization cavities can be vaporized after a few seconds, so as to improve the heating efficiency of the heat plate 60 and the water vaporization rate.

[0159] Specifically, the second water pump 31 is started, and after the second water pump 31 pumps the second amount of water into the heat plate 60, the second heater 32 is started to heat the heat plate 60, vaporize the amount of water in the heat plate 60, and discharge steam from the vaporization cavities in the heat plate 60 to cook the food materials contained in the steamer 50.

[0160] It should be noted that since there can be water in the heat plate 60 when cooking starts, the first time the second amount of water is added to the heat plate 60, the amount of water in the heat plate 60 can be too much to cause the water to overflow. Therefore, the fourth amount of water can be added when the water is first added, and the fourth amount of water is less than the second amount of water. Since whether to pump water into the heat plate 60 is determined by judging whether the heat plate 60 is dry, after the first time the water is pumped, the second amount of water can be directly pumped into the heat plate 60 in the subsequent pumping process.

[0161] In this embodiment, the second amount of water can be a fixed value, such as 50-100g, or can be calculated according to the area of the heat plate 60, wherein the bottom area of the heat plate 60 is S, the optimal liquid level height is h, and the second amount of water is calculated according to the bottom area of the heat plate 60 and the optimal liquid level height.

[0162] In this embodiment, when the heat plate 60 has sufficient residual water, the temperature of the heat plate 60 will be maintained at a constant temperature. After the residual water in the heat plate 60 is evaporated, the temperature of the heat plate 60 will continue to rise. When the temperature of the second heater 32 rises to the first temperature and the remaining cooking time is greater than the preset time, it can be determined that the heat plate 60 is in a dry state due to lack of water, the heating of the heat plate 60 is stopped, the second water pump 31 is started to pump the second amount of water into the heat plate 60 again, and the second heater 32 is started to heat the heat plate 60 again, and the cycle is repeated.

[0163] Since the remaining cooking time is less than or equal to the preset time, when the temperature of the second heater 32 is greater than the first temperature, the second amount of water is pumped into the heat plate 60 again. At the end of the cooking time, there will be some residual water in the heat plate 60.

[0164] To ensure that there is no large amount of residual water on the surface of the hot plate 60 at the end of cooking, and the hot plate 60 is not dry, when the temperature of the second heater 32 is greater than the first temperature, the second heater 32 is turned off, the second water pump 31 is started, and the third water amount of water is pumped into the hot plate 60, wherein the third water amount is less than the second water amount.
