[0059] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0061] A first aspect of an embodiment of the present invention provides a steamer, please refer to Figure 1 , comprising: a nozzle assembly 1, an air compression assembly 2 and a control assembly. The nozzle assembly 1 is arranged on the side wall of the steamer inner container 3, and the opening direction of the nozzle assembly 1 faces the top wall of the inner container 3. The air compression assembly 2 is arranged between the outer shell of the steamer and the inner container 3, and is connected to the nozzle assembly 1 by pipeline. The control assembly is electrically connected to the air compression assembly 2, and controls the air compression assembly 2 to deliver gas to the top wall of the inner container 3 through the nozzle assembly 1.

[0062] The above-mentioned steamer conveys air flow to the top wall of the steamer inner tank 3 through the air compression component 2 and the nozzle arranged on the side wall of the steamer inner tank 3, blows condensed water condensed on the top wall of the inner tank 3 to the side wall of the inner tank 3, and reduces the condensed water condensed on the top wall of the inner tank 3 by high-temperature steam, avoids condensed water dripping onto food, improves the taste and hygiene of the food, and enhances the user experience.

[0063] In one implementation of the embodiment of the present invention, the nozzle assembly 1 is arranged on any side of the side wall of the inner container 3 .

[0064] Optionally, the nozzle assembly 1 includes a nozzle. The opening direction of the nozzle is toward the middle area of ​​the top wall of the inner liner 3, and can also be toward the edge area close to one side of the nozzle. Preferably, the opening direction of the nozzle is toward the central area of ​​the top wall of the inner liner 3, and the airflow output by the air compression assembly 2 is directly blown toward the central area of ​​the top wall of the inner liner 3, so as to blow the condensed water condensed on the top wall of the inner liner 3 toward the side wall and leave it along the side wall, and reduce the condensed water condensed on the top wall of the inner liner 3.

[0065] Optionally, the nozzle assembly 1 may also include a plurality of nozzles. The plurality of nozzles are arranged linearly and are at the same distance from the top wall of the inner liner 3. The plurality of nozzles linearly arranged on a side wall of the inner liner 3 deliver gas to the top wall of the inner liner 3, so that multiple gas paths are blown toward the top wall of the inner liner 3 at the same time, thereby increasing the gas flow area.

[0066] In another implementation of the embodiment of the present invention, the nozzle assembly 1 is arranged on two adjacent or opposite sides of the side wall of the inner container 3 .

[0067] Optionally, the nozzle assembly 1 includes a plurality of nozzles, and the plurality of nozzles are at the same distance from the top wall of the inner pot 3. The opening direction of the nozzle on one side of the side wall of the inner pot 3 forms a first preset angle with the corresponding side wall of the inner pot 3; the opening direction of the nozzle on the other side of the side wall of the inner pot 3 forms a second preset angle with the corresponding side wall of the inner pot 3; the first preset angle is greater than the second preset angle. The angles between the opening direction of the nozzle on one side of the side wall of the inner pot 3 and the opening direction of the nozzle on the other side of the side wall of the inner pot 3 and their respective corresponding side walls of the inner pot 3 are different, and the directions of the two output airflows are different, thereby avoiding mutual interference of the airflows and improving the cleaning effect of the condensed water on the top wall of the inner pot 3. In addition, the nozzle assembly 1 outputs airflow in multiple directions, which can improve the gas circulation effect inside the steamer, improve the heating balance of the food in the steamer, improve the taste of the food, and meet the needs of users.

[0068] Optionally, the nozzle assembly 1 includes a plurality of nozzles, and the opening directions of the plurality of nozzles are at the same preset angle with the corresponding side walls of the inner liner 3. The distance between the nozzle on one side of the side wall of the inner liner 3 and the top wall of the inner liner 3 is a first preset distance; the distance between the nozzle on the other side of the side wall of the inner liner 3 and the top wall of the inner liner 3 is a second preset distance; the first preset distance is greater than the second preset distance. By setting the distance values ​​between the nozzles on different side walls of the inner liner 3 and the top wall of the inner liner 3 to different values, it is also achieved that the nozzles of the nozzle assembly 1 located on different side walls of the inner liner 3 output airflows in different directions, thereby avoiding mutual interference of airflows and improving the cleaning effect of condensed water on the top wall of the inner liner 3. The above-mentioned arrangement of the nozzle assembly 1 also promotes the circulation effect of the steamer airflow.

[0069] The arrangement of one or more nozzles of the nozzle assembly 1 is only for illustrating the technical solution of the present invention, but the present invention is not limited thereto. As long as a nozzle is arranged in the steamer inner tank 3, it falls within the protection scope of the present invention.

[0070] In one embodiment of the present invention, the steamer also includes a valve assembly. The valve assembly corresponds to the nozzle assembly 1. The valve assembly is also electrically connected to the control assembly. The control assembly controls the opening and closing of the valve assembly. When the air compression assembly 2 is working, the valve assembly is opened to output the gas; when the air compression assembly 2 is not working, the valve assembly is closed to close the gas delivery pipeline. By arranging a valve assembly controlled by the control assembly on the nozzle assembly 1, it is realized that the air compression assembly 2 is connected to the inner tank 3 only when the gas is output, avoiding high-temperature gas from entering the gas delivery pipeline and the inner wall of the air compression assembly 2 and causing damage to both, while reducing the high temperature resistance requirements of the materials of the air compression assembly 2 and the gas delivery pipeline, and reducing the cost. When the nozzle assembly 1 includes multiple nozzles, the valve assembly also includes multiple valves accordingly, and the valves correspond to the nozzles one by one. The multiple valves are electrically connected to the control assembly respectively, and the control assembly can uniformly control the opening or closing of the multiple valves, or can separately control the nozzles on each side of the side wall of the inner tank 3, or can separately control one or more valves among the multiple valves.

[0071] In another embodiment of the present invention, the steamer further comprises a valve assembly. The valve assembly is arranged on the pipeline connecting the air compression assembly 2 and the nozzle assembly 1; the valve assembly is electrically connected to the control assembly. The valve assembly is arranged on the main pipeline of gas delivery, and the gas delivery can be controlled by only setting one valve. The control assembly only needs to control one valve to realize the closing and opening of the gas circuit, thereby reducing the cost of the valve assembly and the control assembly.

[0072] In one embodiment of the present invention, the steamer further comprises: a heating component, which is arranged on the gas pipeline connecting the air compression component 2 and the nozzle component 1 to heat the gas output by the air compression component 2; the heating component is electrically connected to the control component. The heating component heats the gas in the gas pipeline, thereby preventing the low-temperature airflow output by the air compression component 2 from entering the steamer inner tank 3, thereby reducing the temperature of the high-temperature steam in the inner tank 3, and improving the heating effect of the food.

[0073] In one embodiment of the present invention, the steamer further comprises at least one temperature sensor, which is disposed on the inner wall of the inner pot 3 and is electrically connected to the control component to detect the temperature of the high-temperature gas in the inner pot 3 .

[0074] Preferably, at least one temperature sensor is arranged on the top wall of the inner container 3 .

[0075] Optionally, the flow rate range of the gas output by the air compression component 2 is 0.05m / s-0.35m / s.

[0077] S100, obtaining the temperature value of the steamer inner container 3.

[0078] S200, comparing the temperature value with a preset temperature value.

[0079] S300, when the temperature value is greater than the preset temperature value, the air compression component 2 is controlled to deliver gas to the top wall of the inner container 3 at a preset gas flow rate.

[0080] Optionally, when the temperature value in step S300 is greater than the preset temperature value, the air compression component 2 is controlled to deliver gas to the top wall of the inner liner 3 at a preset gas flow rate, including: when the temperature value is greater than the first preset temperature value, the air compression component 2 is controlled to deliver gas to the top wall of the inner liner 3 at the first preset gas flow rate.

[0081] Preferably, the numerical range of the first preset temperature value is 80° C.-85° C.; and / or the numerical range of the first preset gas flow rate is 0.1 m / s-0.2 m / s.

[0082] Optionally, when the temperature value of the steam box inner tank 3 is greater than a preset temperature value, the air compression component 2 is controlled to deliver gas to the top wall of the inner tank 3 at a preset gas flow rate, and further includes:

[0083] Furthermore, when the temperature value of the steamer inner tank 3 continues to rise and is greater than the second preset temperature value, the air compression component 2 is controlled to deliver gas to the top wall of the inner tank 3 at the second preset gas flow rate.

[0084] Preferably, the numerical range of the second preset temperature value is 95° C.-100° C.; and / or the numerical range of the second preset gas flow rate is 0.2 m / s-0.3 m / s.

[0085] The air compression component 2 adopts multi-gear gear control according to the different temperatures in the inner liner 3. When the temperature in the inner liner 3 is low, a low-speed output airflow is adopted, thereby reducing the power consumption of the air compression component 2 and reducing the noise of the air compression component 2.

[0086] If a plurality of temperature sensors are provided in the steamer inner container 3, then obtaining the temperature value of the steamer inner container 3 and comparing the temperature value with the first preset temperature value in step S100 and step S200 include the following steps:
