[0034] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0035] This embodiment provides a steam cooking device, as Figure 1 , Figure 2 and Figure 6 shown, which includes a box body 100, an inner container 200, a steam generating device, and a steaming box ④ with a cooking volume smaller than that of the inner container 200. The inner container 200 is accommodated in the box body 100; the steam generating device includes a main steam outlet pipe and a secondary steam outlet pipe. The steam outlet of the main steam outlet pipe is the main steam outlet, and the main steam outlet is communicated with the inner container 200, and the main steam outlet pipe is provided with a main control valve 351; the steam outlet of the secondary steam outlet pipe is the secondary steam outlet, and the secondary steam outlet is communicated with the steaming box 400, and the secondary steam outlet pipe is provided with a secondary control valve.

[0036] The steam cooking device provided in this embodiment includes a box body 100 serving as a housing and used for installing various components, an inner container 200 for providing a cooking cavity for a large amount of food, a steaming box 400 for providing a cooking cavity for a small amount of food, and a steam generating device for generating steam. Among them, the steam generating device supplies steam to the inner container 200 through a main steam outlet pipe, and a main control valve 351 capable of controlling the on / off state inside it is installed on the main steam outlet pipe. The steam generating device supplies steam to the steaming box 400 through a secondary steam outlet pipe, and a secondary control valve capable of controlling the on / off state inside it is installed on the secondary steam outlet pipe.

[0037] When a user needs to use the steam cooking device to cook food with steam, when the amount of food is large, the inner container 200 can be selected to cook the food. Specifically, the food is placed in the inner container 200, and the steam generating device and the main control valve 351 are opened (at this time, the secondary control valve is in the closed state, and steam cannot be output through the secondary steam outlet pipe). The steam generated by the steam generating device is transported to the inside of the inner container 200 through the main steam outlet pipe to perform steam cooking on the food inside the inner container 200. When the amount of food is small, the steaming box 400 can be selected to cook the food. The food is placed in the steaming box 400, and it is ensured that the steaming box 400 is connected to the secondary steam outlet. The steam generating device and the secondary control valve are opened (at this time, the main control valve 351 is in the closed state, and steam cannot be output through the main control valve 351). The steam generated by the steam generating device is transported to the inside of the steaming box 400 through the secondary steam outlet pipe to perform steam cooking on the food inside the steaming box 400. Since the volume of the steaming box 400 is smaller than that of the inner container 200, the steam can fill the volume of the steaming box 400 to achieve steam cooking of the food. On the basis of achieving sufficient steam cooking of the food, by reducing the cooking cavity, the time consumed for steam output can be effectively shortened, the steam consumption can be reduced, and the energy consumption can be lowered. Specifically, as Figure 5 shown, a steam vent 210 can be opened in the inner container 200, and the steam outlet end of the main steam outlet pipe is connected to the steam vent 210, thereby realizing the connection between the main steam outlet and the inner container 200.

[0038] In addition, when the amount of food to be cooked is greater than the capacity of the inner container 200, the food can also be dispersed and placed in the inner container 200 and the steaming box 400. The steam generating device, the main control valve 351, and the secondary control valve are opened, and steam is simultaneously transported into the inner container 200 and the steaming box 400 for synchronous cooking of the inner container 200 and the steaming box 400, thereby increasing the range of the amount of food that the steam cooking device can cook and correspondingly improving its applicability.

[0039] Optionally, in this embodiment, as Figure 2As shown, an installation space is formed between the box body 100 and the inner liner 200. The box body 100 is provided with an opening 110. A driving component 500 is installed in the installation space. The driving end of the driving component 500 is connected to the auxiliary steam outlet pipe. The driving component 500 is used to drive the auxiliary steam outlet to extend out of the box body 100 through the opening 110 or retract into the installation space; the steaming box 400 is detachably connected to the auxiliary steam outlet. Since the steaming box 400 is detachably connected to the auxiliary steam outlet, when it is necessary to use the steaming box 400 to steam-cook food, the steaming box 400 can be disassembled from the auxiliary steam outlet, and then the steaming box 400 can be placed at a convenient operation position for loading food. Then, control the driving component 500 to drive the auxiliary steam outlet to extend out of the box body 100 to facilitate the connection between the steaming box 400 and the auxiliary steam outlet. After the two are connected, turn on the steam generating device and the auxiliary control valve, and steam enters the steaming box 400 to steam-cook the food therein; after cooking is completed, turn off the steam generating device and the auxiliary control valve, the steaming box 400 can be removed, and then control the driving component 500 to drive the auxiliary steam outlet to retract into the installation space to facilitate the removal of the food in the steaming box 400 and reduce the occurrence of the situation that the auxiliary steam outlet extends out of the box body 100 and is easily damaged and affects the overall regularity of the steam cooking device when the steam cooking device is on standby or in the closed state. Optionally, the main steam outlet pipe and the auxiliary steam outlet pipe can be flexible pipes made of materials such as silicone hoses, and the pipe body has a sufficient length to enable the pipe body to stretch or retract with the driving component 500.

[0040] The above is a usage method when the steaming box 400 is located outside the box body 100. When the steaming box 400 can be accommodated in the installation space, during the steam cooking process, place the steaming box 400 in the installation space, the steaming box 400 is communicated with the auxiliary steam outlet, turn on the steam generating device and the auxiliary control valve, and steam enters the steaming box 400 to cook the food therein; after cooking is completed, it is possible to control the driving component 500 to drive the auxiliary steam outlet to extend toward the opening 110 (the driving stroke of the driving component 500 can be controlled according to actual needs, and the auxiliary steam outlet may not extend out of the opening 110, as long as the steaming box 400 can be pushed out), and push out the steaming box 400. The user can disassemble the steaming box 400 from the auxiliary steam outlet, and then control the driving component 500 to drive the auxiliary steam outlet to retract into the installation space, and then take out the food from the steaming box 400.

[0041] The setting of the above driving component 500 can facilitate the disassembly and assembly of the steaming box 400, enable the steaming box 400 to be used independently, and thus improve the convenience of taking and placing food in the steaming box 400 and cleaning the steaming box 400; in addition, it can also ensure that when the steam cooking device is on standby or in the closed state, the auxiliary steam outlet is located in the installation space to reduce the collision and other damages of external factors to the auxiliary steam outlet and improve the overall regularity of the steam cooking device. Specifically, the driving component 500 can drive the auxiliary steam outlet to extend out through the top of the box body 100 or through the side of the box body 100.

[0042] Optionally, the steam generating device may also be located in the installation space. The box body 100 can protect the steam generating device to reduce damage to the steam generating device caused by external factors and ensure its normal use. In addition, it can also further improve the overall regularity of the steam cooking device. Specifically, the steam generating device may include a water tank 310, a water pump 320, and an evaporator 330. The water tank 310 is connected to the evaporator 330 through a water delivery pipe. The water pump 320 is installed on the water delivery pipe. The evaporator 330 can heat water to generate steam and deliver it to the inner container 200 or the steaming box 400.

[0043] In this embodiment, as Figure 2 shown, a partition 120 can be fixedly installed in the installation space. The partition 120 is located at the top of the inner container 200. The driving component 500 is installed on the partition 120 and is used to drive the lifting of the auxiliary steam outlet. The opening 110 is located above the auxiliary steam outlet. Here is a specific form of the installation and driving path of the driving component 500. First, during use, the partition 120 is located at the bottom of the driving component 500 and the steaming box 400 to support both of them. The support stability is high, and it can reduce the damage to the strength and sealing performance of the inner container 200 caused by the direct connection between the driving component 500 and the inner container 200. Second, the partition 120 isolates the inner container 200 and working components such as the driving component 500 in the upper and lower two spaces, which can effectively reduce the adverse impact on the operation of the working components caused by the heat transfer of the inner container 200 to the working components and ensure the normal operation of the working components. In addition, the working components and the inner container 200 are distributed up and down, which can also reduce the area occupied by placing the steam cooking device. Third, the steaming box 400 is disassembled and assembled with the auxiliary steam outlet at the top of the box body 100, which is more convenient for the user to operate. Specifically, the partition 120 can be arranged approximately horizontally to improve the support stability and firmness of the partition 120 for the working components. It should be noted that the partition 120 can be a plate member, such as a flat plate or a rib plate, or a plate integrally fixed with the top plate of the inner container 200 or the top plate of the inner container 200 itself, or other components fixed to the box body for installing the driving component 500.

[0044] In this embodiment, a lifting box 600 can be fixedly connected to the driving end of the driving component 500. The lifting box 600 is provided with an installation hole. The steam outlet end of the auxiliary steam pipe is inserted into the installation hole from the inside to the outside. The opening 110 matches the lifting box 600. Here is a specific form of using the steaming box 400 outside the box body 100. When not in use, control the driving component 500 to drive the lifting box 600 to descend along the opening 110 to the installation space. Preferably, as Figure 4As shown, when the lifting box 600 descends to the installation space, the top surface of the lifting box 600 is approximately coplanar with the top surface of the box body 100, thereby improving the overall regularity of the box body 100 and reducing the pollution of dust and the like to the installation space; when the steaming box 400 is needed to cook food, the control driving assembly 500 drives the lifting box 600 to rise along the opening 110, as shown in FIG. Figure 1 and Figure 3 As shown, the lifting box 600 drives the auxiliary steam outlet pipe and the auxiliary steam outlet to rise synchronously with it. When the auxiliary steam outlet reaches the set external position outside the box body 100, the steaming box 400 is connected to the auxiliary steam outlet, and then the steam generating device and the auxiliary control valve are turned on, and steam enters the steaming box 400 to cook the food therein; after cooking is completed, the steaming box 400 is removed, and the control drive assembly 500 drives the lifting box 600 and the auxiliary steam outlet pipe to descend to their original position.

[0045] In this embodiment, there are two auxiliary steam outlet pipes, auxiliary control valves, steaming boxes 400 and mounting holes, and the four correspond to each other one by one; the two auxiliary steam outlets are both located on the side walls of the lifting box 600, and are spaced apart in the up and down directions; the steam cooking device also includes a processor, the box body 100 is provided with a control panel 130, the control panel 130 is provided with a main mode, a first auxiliary mode and a second auxiliary mode, the steam generating device, the driving assembly 500, the main control valve 351 and the two auxiliary control valves are all connected to the processor. This is the specific form when there are two steaming boxes 400. When in use, you can choose to use the inner pot 200 alone, use one steaming box 400 or use two steaming boxes 400 at the same time according to the amount of food. When using the inner pot 200 alone, you can choose the main mode. The processor receives a signal to turn on the steam generating device and the main control valve 351, and steam enters the inner pot 200 to cook the food therein; specifically, you can use the off option or menu mode to turn off the steam generating device and the main control valve 351. As Figure 5 As shown, the dotted lines represent the pipeline connection relationship between different communication ports.

[0046] The lower one of the two auxiliary steam outlets is set as the first auxiliary steam outlet 342, the auxiliary steam outlet pipe connected to the first auxiliary steam outlet 342 is the first auxiliary steam outlet pipe 341, the auxiliary control valve on the first auxiliary steam outlet pipe 341 is the first auxiliary control valve 352, and the mounting hole on the lifting box 600 connected to the first auxiliary steam outlet pipe 341 is the first mounting hole 610; the upper one is set as the second auxiliary steam outlet 344, the auxiliary steam outlet pipe connected to the second auxiliary steam outlet 344 is the second auxiliary steam outlet pipe 343, the auxiliary control valve on the second auxiliary steam outlet pipe 343 is the second auxiliary control valve 353, and the mounting hole on the lifting box 600 connected to the second auxiliary steam outlet pipe 343 is the second mounting hole 620. When a steam box 400 needs to be used, the first auxiliary mode can be selected. When the processor receives the signal, it controls the drive component 500 to drive the lifting box 600 to move upward a certain distance. Specifically, the distance can be half of the driving stroke of the drive component 500, such asFigure 3 As shown, the first auxiliary steam outlet 342 is exposed outside the box body 100. When the steaming box 400 is placed on the top of the box body 100, the first auxiliary steam outlet 342 can be connected to the steaming box 400. Subsequently, the steam generating device and the first auxiliary control valve 352 are opened (a signal can be transmitted to the processor based on the connection state between the steaming box 400 and the first auxiliary steam outlet 342, and the processor correspondingly controls the on / off states of the steam generating device and the first auxiliary control valve 352; alternatively, the steam generating device and the first auxiliary control valve 352 can be individually operated for on / off). Steam enters the steaming box 400 through the first auxiliary steam pipe 341 for cooking. After cooking is completed, the steaming box 400 is removed, and the processor controls the driving component 500 to drive the lifting box 600 to return to its original position.

[0047] When two steaming boxes 400 are needed, the second auxiliary mode can be selected. The processor controls the driving component 500 to drive the lifting box 600 to rise a certain distance. Specifically, this distance can be one driving stroke of the driving component 500, such as Figure 1 As shown, both the first auxiliary steam outlet 342 and the second auxiliary steam outlet 344 extend outside the box body 100. Two steaming boxes 400 are stacked and placed on the top of the box body 100, and the two steaming boxes 400 can be respectively connected to the first auxiliary steam outlet 342 and the second auxiliary steam outlet 344. Subsequently, the steam generating device, the first auxiliary control valve 352, and the second auxiliary control valve 353 are opened, and steam enters the two steaming boxes 400 simultaneously for cooking. After cooking is completed, the two steaming boxes 400 are removed, and the processor controls the driving component 500 to drive the lifting box 600 to descend to its original position.

[0048] Optionally, the processor can also control the heating power of the steam generating device. When the main mode is selected, the processor controls the steam generating device to perform full-power heating to increase the steam generation speed; when the first auxiliary mode or the second auxiliary mode is selected, the processor can control the steam generating device to perform half-power heating, reducing the waste of excessive steam while ensuring steam supply. Specifically, the evaporator 330 can adopt a structure with two heating tubes. When the main mode is selected, the processor turns on the two heating tubes; when the first auxiliary mode or the second auxiliary mode is selected, the processor turns on one heating tube. In addition, the power of the steam generating device can also be controlled through a thyristor scheme.

[0049] Optionally, the inner container 200 and two steaming boxes 400 can also be used simultaneously to cook food to improve the applicability of the steam cooking device. In addition, it should be noted that in this application, the connection relationship between the processor and the steam generating device, the driving component 500, the main control valve 351, and the two auxiliary control valves belongs to the protection scope of this application. The setting and transmission of the control program between the processor and the above-mentioned working components belong to the prior art and do not belong to the improvement of this application.

[0050] In addition to the above two, in this embodiment, the auxiliary steam outlet pipe, the auxiliary control valve, and the steaming box 400 can also be multiple, and the three correspond to each other one by one.

[0051] In addition to the form located outside the box body 100 as described above, the steaming box 400 can also be located inside the box body 100. Specifically, in this embodiment, a lifting plate 700 can be fixedly connected to the driving end of the driving component 500. The lifting plate 700 is provided with a connecting hole 710, and the steam outlet end of the auxiliary steam outlet pipe is inserted into the connecting hole 710; the opening 110 matches the steaming box 400. When the steaming box 400 needs to be used, the steaming box 400 can be loaded into the installation space through the opening 110. The steaming box 400 is communicated with the auxiliary steam outlet. The steam generating device and the auxiliary control valve are opened, and the steam enters the steaming box 400 for cooking; after cooking is completed, the steam generating device and the auxiliary control valve are closed, and the driving component 500 is controlled to drive the lifting plate 700 to rise. The lifting plate 700 pushes the steaming box 400 upward, and the steaming box 400 is higher than the box body 100 or completely reaches outside the box body 100. The user removes the steaming box 400 to take out the food; then the driving component 500 is controlled to drive the lifting plate 700 to descend to the original position.
