Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to a steaming, baking and sterilizing integrated machine. BACKGROUND

[0002] The steaming, baking and sterilizing integrated machine integrates the functions of steaming, baking and sterilizing, thereby improving the diversity and convenience of cooking and increasing the safety of cleaning tableware. In the steaming function, water in the water storage box is intermittently delivered to the high-temperature heating disc by the water pump to rapidly heat and vaporize to generate water vapor, which diffuses in the steaming and baking cavity. In the baking function, high-temperature hot air is generated by the electric heating element to act on the food in a circulating manner. In the sterilizing function, ultraviolet rays and / or ozone are used for sterilization, and high-temperature drying is used to ensure that the tableware can be stored in a dry environment.

[0003] In the related art, in order to meet the normal use of each function, the steaming, baking and sterilizing integrated machine needs to be provided with independent steaming function structure, baking function structure and sterilizing function structure, resulting in a relatively complex overall structure.

The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.

[0028] Please refer to Figures 1 to 5 , an embodiment of the present application provides a steaming, baking and sterilizing integrated machine, which comprises a steaming and baking inner container 11 and a sterilizing inner container 12, both of which are arranged in a first direction. The steaming and baking inner container 11 can be used for cooking food, and the sterilizing inner container 12 can be used for sterilizing tableware. The steaming, baking and sterilizing integrated machine further comprises a steam generator 22 and a fan structure 40. The steam generator 22 is arranged in the steaming and baking inner container 11 and / or the sterilizing inner container 12, and at least one of the steaming and baking inner container 11 and the sterilizing inner container 12 is capable of communicating with the steam generator 22. The fan structure 40 comprises a first fan 41 and a second fan 42. The first fan 41 is arranged in the steaming and baking inner container 11, and the second fan 42 is arranged in the sterilizing inner container 12.

[0029] When the steaming and roasting inner container 11 is in communication with the steam generator 22, the steam generated by the steam generator 22 acts on the food materials in the steaming and roasting inner container 11 and is uniformly diffused in the steaming and roasting inner container 11 under the action of the first fan 41, for cooking food. When the sterilization inner container 12 is in communication with the steam generator 22, the steam generated by the steam generator 22 acts on the tableware in the sterilization inner container 12 and is uniformly diffused in the sterilization inner container 12 under the action of the second fan 42, to achieve steam sterilization. That is, the same steam generator 22 provides a steam source for the steaming and roasting inner container 11 and the sterilization inner container 12, without the need for the steaming and roasting inner container 11 and the sterilization inner container 12 to separately set up corresponding steam function structures and sterilization function structures, simplifying the structure and facilitating cost reduction; and, such a setting reduces the space occupation of the steam function structure and the sterilization function structure, facilitating the expansion of the size of the sterilization inner container 12 and the steaming and roasting inner container 11.

[0030] Among them, the steaming and roasting inner container 11 and the sterilization inner container 12 can be in communication with the steam generator 22 alternatively, or can be in communication with the steam generator 22 simultaneously. When communicating simultaneously, it is not only used for food material cooking, but also can be used for tableware sterilization.

[0031] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , in an alternative embodiment, the steam generation assembly 20 further comprises a first steam pipeline 101 and a second steam pipeline 102, which are connected in parallel to the steam generator 22, the first steam pipeline 101 is in communication with the steaming and roasting inner container 11, and the second steam pipeline 102 is in communication with the sterilization inner container 12. The first steam pipeline 101 and the second steam pipeline 102 are both provided with a steam control valve. That is, by using the settings of the first steam pipeline 101 and the second steam pipeline 102, the steam in the steam generator 22 can be delivered towards the steaming and roasting inner container 11 and the sterilization inner container 12; and, such a setting can set the steam generator 22 at a relatively distant position, reducing the interference with the functions of the steaming and roasting inner container 11 and the sterilization inner container 12. At the same time, by using the setting of the steam control valve, the on-off of the first steam pipeline 101 and the second steam pipeline 102 can be adjusted, and the delivery direction of the steam, i.e. to the steaming and roasting inner container 11 or the sterilization inner container 12, can be more accurately controlled, to meet the target requirements.

[0032] Specifically, the first steam pipe 101 corresponds to the first steam control valve 31, and the first steam control valve 31 is used to control the opening and closing of the first steam pipe 101; the second steam pipe 102 corresponds to the second steam control valve 32, and the second steam control valve 32 is used to control the opening and closing of the second steam pipe 102. The first steam control valve 31 and the second steam control valve 32 are selectively opened or closed, or simultaneously opened and closed. The first steam control valve 31 and the second steam control valve 32 can both be electromagnetic valves, which are convenient to control; and the flow cross section of the steam can also be changed by adjusting the opening degree of each steam control valve, thereby adjusting the steam delivery amount.

[0033] The steam generator 22 is connected with a three-way pipe. One of the three-way pipe is communicated with the steam generator 22 through a pipe, another is communicated with the first steam pipe 101, and the other is communicated with the second steam pipe 102. The three-way pipe is arranged to facilitate the steam flowing out of the steam generator 22 to be divided into the first steam pipe 101 and the second steam pipe 102.

[0034] In some embodiments, the rear side of the steaming and baking inner container 11 and the disinfecting inner container 12 is respectively provided with a steam interface for connecting the first steam pipe 101 and the second steam pipe 102.

[0035] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , in an optional embodiment, the steam generation assembly 20 includes a water tank 21, and the water tank 21 is connected with the steam generator 22. In actual use, the steam generation assembly 20 further includes a water pump 23, and the water pump 23 is connected between the water tank 21 and the steam generator 22. The water tank 21 can be arranged in the disinfecting inner container 12, and the steam generator 22 can be arranged in the steaming and baking inner container 11, so as to disperse the gravity of the two and maintain the structural stability. The steam generator 22 is provided with a cavity and a heater, and the heater heats the water input in the cavity to make it boil and generate steam.

[0036] Exemplarily, the steaming and baking inner container 11 is provided with a heating disc. The steam generation assembly 20 further comprises a first liquid supply pipeline 103 and a second liquid supply pipeline 104, both of which are connected to the water tank 21, the first liquid supply pipeline 103 is connected to the steam generator 22, and the second liquid supply pipeline 104 is connected to the steaming and baking inner container 11, and the liquid outlet of the second liquid supply pipeline 104 is arranged close to the heating disc. The first liquid supply pipeline 103 and the second liquid supply pipeline 104 are both provided with a water control valve. That is, part of the water in the water tank 21 is transported to the steam generator 22 through the first liquid supply pipeline 103 to generate steam, which in turn acts on the steaming and baking inner container 11 and the sterilization inner container 12. Another part of the water in the water tank 21 is transported to the position close to the heating disc of the steaming and baking inner container 11 through the second liquid supply pipeline 104, and is gasified under the action of high temperature of the heating disc to act on the food material, so that the food material retains moisture and has better taste. The water control valve can adjust the connection state of the first liquid supply pipeline 103 and the second liquid supply pipeline 104 to the water tank 21 respectively.

[0037] Among them, the water control valve adopts a solenoid valve, which is convenient to control.

[0038] Specifically, the first liquid supply pipeline 103 corresponds to the first water control valve 33, which is used to control the on-off of the first liquid supply pipeline 103; the second liquid supply pipeline 104 corresponds to the second water control valve 34, which is used to control the on-off of the second liquid supply pipeline 104. The first water control valve 33 and the second water control valve 34 can be opened and closed at the same time, or can be opened one by one. When the first water control valve 33 is opened, the first liquid supply pipeline 103 is connected, and the water in the water tank 21 is transported to the steam generator 22 under the action of the water pump 23. When the second water control valve 34 is opened, the second liquid supply pipeline 104 is connected, and the water in the water tank 21 is transported to the steaming and baking inner container 11 under the action of the water pump 23.

[0039] In actual use, the water tank 21 is connected with a three-way pipe, one port of the three-way pipe is connected with the water tank 21 through a pipeline, the water pump 23 is arranged on the pipeline, another port is connected with the first liquid supply pipeline 103, and the other port is connected with the second liquid supply pipeline 104.

[0040] Optionally, the first direction is arranged at an angle to the vertical direction, for example, the first direction can be the X-axis direction on the horizontal plane, and the vertical direction is the Z-axis direction, and the two are perpendicular. The steaming, baking and sterilizing all-in-one machine further comprises an upper mounting plate, the upper mounting plate is arranged at the top of the steaming and baking inner container 11 and the sterilization inner container 12, and the steam generator 22 and the water tank 21 are arranged above the upper mounting plate. The arrangement of the upper mounting plate can ensure the stable assembly of the steaming and baking inner container 11 and the sterilization inner container 12, and can increase the assembly space at the top, which is beneficial to the stable support of the water tank 21 and the steam generator 22; and such arrangement isolates the water tank 21 and the steam generator 22 from the steaming and baking inner container 11, thereby reducing the temperature influence.

[0041] The fan structure 40 will be described in detail below.

[0042] like Figures 2 to 4 As shown, in some embodiments, the steam oven liner 11 has a first vent on the side facing the sterilization liner 12, and the sterilization liner 12 has a second vent on the side facing the steam oven liner 11. The first and second vents are spaced apart. A first fan 41 is located at the first vent, and a second fan 42 is located at the second vent to ensure uniform steam diffusion in both the steam oven liner 11 and the sterilization liner 12. This arrangement effectively places the first fan 41 and the second fan 42 between the steam oven liner 11 and the sterilization liner 12, making full use of the space between them and minimizing the space occupied in other directions.

[0043] Furthermore, the first fan 41 and the second fan 42 are coaxially arranged. This arrangement facilitates connection to the same power source, improves structural compactness, and is more conducive to integration between the sterilization inner liner 12 and the steam oven inner liner 11. Specifically, the fan structure 40 also includes a power source and a drive shaft connected to the power source. The first fan 41 and the second fan 42 are both connected to the drive shaft and are arranged at intervals along the axial direction of the drive shaft. The power source, a motor, is located between the first fan 41 and the second fan 42. The drive shaft is divided into a first drive shaft 411 and a second drive shaft 421, which are connected by a coupling. The end of the first drive shaft 411 facing away from the second drive shaft 421 is connected to the first fan 41, and the end of the second drive shaft 421 facing away from the first drive shaft 411 is connected to the second fan 42. Either the first drive shaft 411 or the second drive shaft 421 can be connected to the power source, as long as coaxial drive of the first drive shaft 411 and the second drive shaft 421 can be achieved.

[0044] Both the first fan 41 and the second fan 42 include a base and multiple blades connected to the base, with the blades arranged circumferentially spaced along the base. Each blade can also be integrally formed with the base to improve structural strength. The first fan 41 corresponds to the first base 413 and the first blade 412, and the second fan 42 corresponds to the second base 423 and the second blade 422. The first base 413 is connected to and secured to the end of the first drive shaft, and the second base 423 is connected to and secured to the end of the second drive shaft.

[0045] Each blade includes a first turbulence-inducing section 401 and a second turbulence-inducing section 402 connected to the first turbulence-inducing section 401, which are arranged at an angle. Thus, the first turbulence-inducing section 401 can act on the airflow from a first direction, and the second turbulence-inducing section 402 can act on the airflow from a second direction, thereby turbulenting the airflow from different directions and facilitating faster and more uniform steam diffusion. In actual use, the second turbulence-inducing sections 402 corresponding to each blade in the first fan 41 are all located on the same side of their respective first turbulence-inducing sections 401.

[0046] Optionally, the steaming and baking inner container 11 and the sterilization inner container 12 are each provided with a fan baffle 50. The steaming and baking inner container 11 corresponds to a first fan baffle 50, and the sterilization inner container 12 corresponds to a second fan baffle 50. The first fan baffle 50 is arranged at the first air vent, and the second fan baffle 50 is arranged at the second air vent. Each fan baffle 50 is provided with a plurality of air vents arranged at intervals, which facilitates air circulation. The fan baffle 50 is used to protect the first fan 41 and the second fan 42 from being interfered by food materials, tableware, and the like, so as to affect rotation.

[0047] Further, each fan baffle 50 is concavely provided with a containing cavity, which is a first containing cavity and a second containing cavity, respectively. The first containing cavity is used to contain the first fan 41, and the second containing cavity is used to contain the second fan 42. The steaming and baking inner container 11 is further provided with a heating pipe, which is contained in the first containing cavity and surrounds the outer circumferential side of the first fan 41, so as to heat the air flow by using the heating pipe. Alternatively, the inner container wall of the steaming and baking inner container 11 is concavely provided with the first containing cavity, and the second fan baffle 50 is concavely provided with the second containing cavity. As long as the assembly of the first fan 41 and the second fan 42 can be satisfied, this is only an example.

[0048] Please refer to Figures 1 to 5 In actual use, the steaming, baking and sterilizing all-in-one machine has a first state, a second state, a third state and a fourth state, which will be described below.

[0049] In the first state, the first water control valve 33, the first steam control valve 31 and the second steam control valve 32 are opened, and the second water control valve 34 is closed. That is, the steam generator 22 is communicated with the water tank 21 through the first liquid supply pipeline 103, and the steam generator 22 is communicated with the steaming and baking inner container 11 and the sterilization inner container 12 through the first steam pipeline 101 and the second steam pipeline 102, respectively. The water in the water tank 21 is transported to the steam generator 22 under the action of the water pump 23 to generate steam. The steam in the steam generator 22 flows to the steaming and baking inner container 11 through the first steam pipeline 101, and flows to the sterilization inner container 12 through the second steam pipeline 102. In this process, the power source is started to drive the first fan 41 and the second fan 42 to rotate simultaneously, so as to accelerate the steam in the steaming and baking inner container 11 and the sterilization inner container 12, respectively, to realize simultaneous cooking and sterilization, and improve work efficiency.

[0050] In the second state, the first steam control valve 31, the first water control valve 33, and the second water control valve 34 are opened, while the second steam control valve 32 is closed. That is, the water tank 21 is connected to the steam generator 22 and the steam oven liner 11 via the first liquid supply pipe 103 and the second liquid supply pipe 104, respectively, and the first steam pipe 101 connects the steam generator 22 and the steam oven liner 11. Part of the water in the water tank 21 flows along the first liquid supply pipe 103 to the steam generator 22 to generate steam, and then is transported to the steam oven liner 11 via the first steam pipe 101; the other part flows directly into the heating plate of the steam oven liner 11 via the second liquid supply pipe 104 for rapid vaporization. During this process, the first fan 41 rotates to accelerate the uniformization of steam; and because the outlets of the first steam pipe 101 and the second liquid supply pipe 104 are different, food can be steam-cooked from different directions, improving cooking efficiency and resulting in fluffier ingredients.

[0051] In the third state, the first water control valve 33 and the first steam control valve 31 are open, while the second steam control valve 32 and the second water control valve 34 are closed. That is, the water tank 21 is connected to the steam generator 22 through the first liquid supply pipe 103, and the steam generator 22 is connected to the steam oven liner 11 through the first steam pipe 101 to supply steam to the steam oven liner 11.

[0052] In the fourth state, the first water control valve 33 and the second steam control valve 32 are open, while the second water control valve 34 and the first steam control valve 31 are closed. That is, the water tank 21 is connected to the steam generator 22 through the first liquid supply pipe 103, and the steam generator 22 is connected to the sterilization inner tank 12 through the second steam pipe 102 to provide steam to the sterilization inner tank 12 to meet the requirements of steam sterilization.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
