[0006] The cleaning steam nozzle is used to spray steam for cleaning oil stains to the facing area, so that the steam sprayed by the cleaning steam nozzle can be used to clean the components arranged in the facing area. The facing area is a space arranged on the main pot cover and facing the inner pot.

[0007] Among them, the steam generating unit is arranged in the first heating unit so that the water working medium can be vaporized by absorbing the heat of the first heating unit. In this way, while the first heating unit heats the cooking area, it can also heat and vaporize the water working medium in the steam generating unit, so that the heat of the first heating unit can be fully utilized and the heat utilization rate of the first heating unit can be improved.

[0008] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are: first, since the first heating unit, the second heating unit and the steam unit are provided, they can be mixed and used in the cooking area to create different cooking environments and enrich the means of cooking food. Secondly, since the steam unit includes the cooking steam nozzle and the cleaning steam nozzle, the steam vaporized in the steam generating unit can be used for cleaning or cooking food. The steam for cleaning and cooking uses the same steam unit, which can reduce the setting of the heating device, simplify the structure of the cooking pot and reduce the manufacturing cost.

[0009] A further technical solution may be that the four cleaning steam nozzles are evenly distributed on the main pot cover, which can increase the spray range of the steam, and can clean the components arranged in the facing area in multiple directions, thereby improving the cleaning intensity of the components.

[0013] A further technical solution may be that the heat-conducting bottom plate has a heat-conducting surface, and the bottom of the inner pot can fit on the heat-conducting surface to conduct heat. The fit means that at least part of the bottom wall of the inner pot is adapted to the shape of the heat-conducting surface, and this part of the bottom wall can fit on the heat-conducting surface, thereby increasing the heat conduction area between the heat-conducting bottom plate and the inner pot and improving the heat conductivity.

In this way, when the steam control valve is in a closed state and the first heating unit is working, the water working medium accumulated in the steam generating unit will be vaporized and gradually dispersed in the steam generating unit and the steam delivery pipeline, and the air pressure in the steam delivery pipeline will gradually increase. When it increases to a certain value, the safety valve will be opened, and the steam will be discharged from the steam delivery pipeline through the steam release end of the safety valve and enter the water tank, thereby discharging the water working medium accumulated in the steam generating unit to avoid the growth of bacteria.

In this way, the hose can be deformed to adapt to the reversal of the main pot cover, so that the steam delivery pipeline can maintain the connection between the steam sending unit and the nozzle.

[0022] A further technical solution may be that the main pot cover is flippably arranged on the pot base via a hinge mechanism, and the hose passes through the hinge mechanism to connect the main pot cover and the pot base.

[0023] A further technical solution may be that a wire passing channel is also provided in the hinge mechanism, and the electrical signal line between the main pot cover and the pot base is a soft signal line and is arranged in the wire passing channel.

[0024] A further technical solution may also include an auxiliary pot cover that can be moved away from the pot base, and the auxiliary pot cover and the main pot cover selectively cover the inner pot; the auxiliary pot cover is used to accumulate a high-pressure environment for cooking in the cooking area of ​​the inner pot to achieve high-pressure cooking, and the auxiliary pot cover is provided with a high-pressure release valve. In this way, different cooking modes can be achieved by replacing different pot covers.

[0025] A further technical solution may also include an auxiliary pot cover detector and a controller, wherein the auxiliary pot cover detector is used to detect whether the auxiliary pot cover has been closed, and the controller is used to respond to the detection signal of the auxiliary pot cover detector to determine whether to allow the second heating unit, the cooking steam nozzle and the motor to be started.

[0026] A further technical solution may be that the controller is also used to control the first heating unit, the second heating unit, the cooking steam nozzle and the motor to work simultaneously in a control scheme.

[0033] The structure of the cooking pot with multiple functions using the technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, a cooking pot with a composite function comprises a pot base 1, an inner pot 2 located in the pot base 1, and a main pot cover 3 for covering the inner pot 2, wherein the inner pot 2 has a cooking area 20 for holding cooked food. A first heating unit 4 is arranged in the pot base 1, and a second heating unit 5 is arranged on the main pot cover 3, wherein the first heating unit 4 and the second heating unit 5 are used to respectively provide heating energy to the cooking area 20 of the inner pot 2.

The cooking steam nozzle 63 is fixedly connected to the main pot cover 3 and its nozzle direction faces the cooking area 20 of the inner pot 2, and is used to spray steam for cooking food to the cooking area 20. In this embodiment, three cooking steam nozzles 63 are arranged on the main pot cover 3. In this way, the steam spray range can be increased, and steam can be sprayed to the cooking area 20 in multiple directions, so that the steam can evenly steam cook the food placed in the cooking area 20. The cleaning steam nozzle 64 is fixedly connected to the main pot cover 3 and its nozzle direction is toward the facing area 31 of the main pot cover 3 facing the inner pot 2, and is used to spray steam for cleaning oil stains to the facing area 31. In this embodiment, four cleaning steam nozzles 64 are evenly distributed on the main pot cover 3. In this way, the steam spray range can be increased, and the components arranged in the facing area 31 can be cleaned in multiple directions, thereby improving the cleaning intensity of the components. Of course, in other embodiments, the cleaning steam nozzle can also include at least two first cleaning steam nozzles evenly distributed at the peripheral position of the facing area and a second cleaning steam nozzle arranged at the top position of the facing area. In this way, the first cleaning steam nozzle and the second cleaning steam nozzle can cooperate to perform three-dimensional cleaning of the components in the facing area, and the cleaning effect is better.

[0035] like Figure 4 and Figure 5As shown, the steam generating unit 61 is arranged in the first heating unit 4 so as to realize the vaporization of the water medium by absorbing the heat of the first heating unit 4. Specifically, the first heating unit 4 includes a bottom heater 4a located below the inner pot 2, and the bottom heater 4a has a bottom heating element (41, 42) and a heat-conducting bottom plate body 43 for receiving the bottom heating element (41, 42) and conducting its heat. The bottom heating element includes a first bottom heating element 41 and a second bottom heating element 42, and the first bottom heating element 41 and the second bottom heating element 42 are respectively configured with different rated heating powers, for example, the power of the first bottom heating element 41 is 1000W, and the power of the second bottom heating element 42 is 350W. The first bottom heating element 41 is arranged in a ring shape, and the second bottom heating element 42 is arranged on the inner ring area defined by the first bottom heating element 41 and is arranged at intervals from the first bottom heating element 41. The steam generating unit 61 is arranged in the interval area between the first bottom heating element 41 and the second bottom heating element 42, and the steam generating unit 61 is arranged around the second bottom heating element 42. The steam generating unit 61 includes an inner ring channel 611 and an outer ring channel 612 which are interconnected. The channel wall of the outer ring channel 612 directly contacts the first bottom heating element 41, and the channel wall of the inner ring channel 611 directly contacts the second bottom heating element 42. Further, the heat-conducting bottom plate 43 has a heat-conducting surface 44, and the bottom of the inner pot 2 can be matched to the heat-conducting surface 44 to conduct heat. The matching means that at least part of the bottom wall of the inner pot 2 is adapted to the shape of the heat-conducting surface 44, and this part of the bottom wall can be attached to the heat-conducting surface 44, so that the heat conduction area between the heat-conducting bottom plate 43 and the inner pot 2 can be increased, and the heat conductivity can be improved. In this embodiment, the heat-conducting surface 44 is a plane, and the bottom of the inner pot 2 is flat. The bottom of the inner pot 2 matches the heat-conducting surface 44 so that a large area of ​​heat conduction can be carried out.

[0036] like Figure 3As shown, the steam outlet of the steam generating unit 61 is connected to the steam delivery pipeline 62, and the steam delivery pipeline 62 extends from the outside of the inner pot 2 to the main pot cover 3 to connect to the nozzles (63, 64). A steam control valve is also included, and the steam control valve is arranged on the steam delivery pipeline 62 for selectively providing steam to the cooking steam nozzle 63 or / and the cleaning steam nozzle 64 according to instructions. In this embodiment, the steam control valve includes a first steam control valve 71 and a second steam control valve 72. The first steam control valve 71 is used to provide steam to the cooking steam nozzle 63 according to instructions; the second steam control valve 72 is used to provide steam to the cooking steam nozzle 64 according to instructions, so that the duration and time of the nozzles (63, 64) spraying steam can be effectively controlled.

[0037] like Figure 3 As shown, it also includes a water supply pipeline 80, the water inlet end 613 of the steam generating unit 61 is connected to the water supply pipeline 80, and a water supply control valve 83 is provided on the water supply pipeline 80, and the water supply control valve 83 is used to provide water working medium to the steam generating unit 61 according to instructions. In this way, the water working medium entering the water supply pipeline 80 can be prevented from penetrating and accumulating in the steam generating unit 61 to breed bacteria through the water supply control valve 83. It also includes a water supply pump 81 and a water storage tank 8, the water inlet of the water supply pipeline 80 is connected to the water storage tank 8, the water supply pump 81 is arranged on the water supply pipeline 80 and is located between the water storage tank 8 and the steam generating unit 61, and the water supply control valve 83 is located between the water storage tank 8 and the water supply pump 81. Further, a safety valve 84 is also provided on the steam delivery pipeline 62, and the steam release end of the safety valve 84 is connected to the water storage tank 8. In this way, when the steam control valves (71, 72) are in a closed state and the first heating unit 4 is working, the water working medium accumulated in the steam generating unit 61 will be vaporized and gradually dispersed in the steam generating unit 61 and the steam conveying pipeline 62, and the air pressure in the steam conveying pipeline 62 will gradually increase. When it increases to a certain value, the safety valve 84 will be opened, and the steam will be discharged from the steam conveying pipeline 62 through the steam release end of the safety valve 84 and enter the water tank, so that the water working medium accumulated in the steam generating unit 61 can be discharged to avoid the breeding of bacteria.

[0038] The first heating unit 4 further includes a side heater 4b (not shown) located at the side of the inner pot 2, the side heater 4b having a side heating element, a heat-conducting side plate body for receiving the side heating element and conducting its heat, and another steam generating unit is arranged in the heat-conducting side plate body. In this way, the first heating unit 4 can heat the food in the cooking area 20 from the side. Of course, in other embodiments, it is also feasible to arrange only one of the bottom heater 4a and the side heater 4b.

[0039] The main pot cover 3 is reversibly arranged on the pot base 1, and at least the part of the steam delivery pipeline 62 used to connect the main pot cover 3 and the pot base 1 is a hose. In this way, the hose can adapt to the reversal of the main pot cover 3 and deform, and keep the steam sending unit and the nozzle connected. The main pot cover 3 is reversibly arranged on the pot base 1 through a hinge mechanism, and the hose passes through the hinge mechanism to connect the main pot cover 3 and the pot base 1. A wire passing channel is also provided in the hinge mechanism, and the electrical signal line between the main pot cover 3 and the pot base 1 is a soft signal line and is arranged in the wire passing channel.

[0040] like Figure 2 As shown, the main pot cover 3 is provided with a rotating blade 32, a motor 33 driving the rotating blade 32 to rotate, and an isolation cover 34, the space below the isolation cover 34 is defined as the facing area 31, the second heating unit 5 is arranged in the space below the isolation cover 34, the rotating blade 32 is also arranged in the space below the isolation cover 34 and is located between the isolation cover 34 and the second heating unit 5, the motor 33 is located above the isolation cover 34, and its output shaft passes through the isolation cover 34 and is connected to the rotating blade 32. During the cooking process, the second heating unit 5 can directly face the cooking area 20 of the inner pot 2 so as to directly provide radiant heat energy to the cooking area 20.

[0041] A further technical solution may also include an auxiliary pot cover (not shown) that can be moved away from the pot base 1, and the auxiliary pot cover and the main pot cover 3 selectively cover the inner pot 2; the auxiliary pot cover is used to accumulate a high-pressure cooking environment in the cooking area 20 of the inner pot 2 to achieve high-pressure cooking, and the auxiliary pot cover is provided with a high-pressure release valve. In this way, different cooking modes can be achieved by replacing different pot covers. It also includes an auxiliary pot cover detector (not shown) and a controller 9, the auxiliary pot cover detector is used to detect whether the auxiliary pot cover has been closed, and the controller 9 is used to respond to the detection signal of the auxiliary pot cover detector to determine whether to allow the second heating unit 5, the cooking steam nozzle 63 and the motor 33 to be started. In this way, it can be avoided that the second heating unit 5, the cooking steam nozzle 63 and the motor 33 are turned on by Wu operation when the auxiliary pot cover is not closed in place, which is conducive to improving the safety of the cooking pot. The controller 9 is also used to control the first heating unit 4, the second heating unit 5, the cooking steam nozzle 63 and the motor 33 to work simultaneously in a control scheme. In this way, the three-dimensional steam air frying cooking mode can be turned on to heat and cook the food, which can keep the moisture of the food and make the food have a loose surface.

[0042] According to the above technical solution, firstly, since the steam unit 6 includes the cooking steam nozzle 63 and the cleaning steam nozzle 64, the steam vaporized in the steam generating unit 61 can be used for cleaning or cooking food. The steam for cleaning and cooking uses the same steam unit, which can reduce the setting of the heating device and simplify the structure and manufacturing cost of the cooking pot. Secondly, since the first heating unit 4, the second heating unit 5 and the steam unit 6 are provided, they can be mixed and used in the cooking area 20 to create different cooking environments and enrich the cooking methods of food. For example, steaming and baking cooking can be performed: Figure 6As shown, first, the first heating unit 4 works to preheat the inner pot 2 so that the temperature of the inner pot 2 reaches 200°C, so as to avoid a large amount of condensed water in the inner pot 2 when the steam is sprayed later. The main pot cover 3 is opened to put the food into the cooking area 20 of the inner pot 2. Then the water supply pump 8 is started, the first steam control valve 71 is opened, the water medium in the water storage tank 8 enters the steam generating unit 61 to form steam, the steam enters the steam delivery pipeline 62 and finally is sprayed into the cooking area 20 through the cooking steam nozzle 63 to steam cook the food. When the amount of steam in the cooking area 20 reaches a preset value, the water supply pump 8 and the first heating unit 4 stop working, the first steam control valve 71 is closed, and the second heating unit 5 is turned on to bake and heat the food placed in the cooking area 20. After heating for a preset time or reaching a preset temperature, the second heating unit 5 stops working and the first heating unit 4 starts heating. When the first heating unit 4 reaches the preset temperature, the water supply pump 8 is started, the first steam control valve 71 is opened, and cooking steam is supplied to the food in the cooking area 20 again. After the preset cooking time or number of cycles is met, the water supply pump 8 and the first heating unit 4 stop working, the first steam control valve 71 is closed, and the second heating unit 5 is opened to bake the food for the last time to make the food crispy. After steaming and baking, the food not only has a crispy skin, but also remains fresh and juicy inside without being too dry and hard, and has a very good taste.
