Description

Technical Field

[0001] This utility model belongs to the technical field of rice steamer, specifically relating to an energy-saving rice steamer with internal steam circulation. Background Technology

[0002] A rice steamer, also known as a rice cabinet or rice cart, is a large kitchen appliance that uses electricity or gas to generate steam for cooking rice, steamed buns, dumplings, seafood, poultry, fish, and other foods. Existing commercial rice steamers have a water tank directly connected to the internal steaming chamber. Steam flows upwards through channels around the steaming trays and is finally discharged through the vent. During this upward flow, the steam heats the steaming trays. When there are many trays, the varying heat exchange rates between them lead to uneven heating. Poor temperature uniformity in the rice steamer results in rice with inconsistent textures and softness, affecting the taste.

[0003] In addition, after the steam flows into the rice steamer, a large amount of steam rises directly along the steam channel to the exhaust port and is discharged. Only a portion of the steam can enter the steaming trays for heat exchange, resulting in a large amount of steam waste heat loss. Utility Model Content

Obviously, the described embodiments are some of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0016] In the description of the utility model, it needs to be explained that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0017] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0018] For example, Figures 1-4As shown, the energy-saving rice steaming box with steam internal circulation comprises a rice steaming box cabinet 1, a cabinet door 2 is installed on the rice steaming box cabinet 1, a rice steaming chamber is arranged in the rice steaming box cabinet 1, a water tank 9 is arranged below the rice steaming chamber, an electric heater 11 is installed in the water tank 9, the upper end of the water tank 9 is communicated with the rice steaming chamber, a plurality of steaming trays 6 are sequentially installed in the rice steaming chamber from bottom to top, the two sides of the steaming tray 6 are respectively arranged on a steaming tray support 12, the steaming tray support 12 is fixedly connected to the inside of the rice steaming chamber, one end of the steaming tray 6 is close to the cabinet door 2, and the other end forms a steam flow channel 14 between the inner wall of the rice steaming chamber, a plurality of guide plates 13 are inserted in the steam flow channel 14, the guide plate 13 corresponds to the steaming tray 6 in one-to-one correspondence, the upper end of the guide plate 13 is obliquely cut upwards and close to the corresponding steaming tray 6, and the lower end of the guide plate 13 is located in the steam flow channel 14. The heat exchange is strong in the bottom region of the rice steaming chamber, and the heat exchange is poor in the middle and upper regions. The guide plate 13 can be arranged at the middle and upper positions (the guide plate 13 is not arranged at the bottom of the rice steaming chamber), when the steam rises to the position of the guide plate 13, the flow resistance increases, a small amount of steam continues to rise, and a large amount of steam flows to the bottom of the steaming tray 6 to be heated, and the heat exchange performance of the middle and upper regions is obviously strengthened.

[0019] Further, the two sides of the steam flow channel 14 are respectively provided with inclined insertion grooves 15, and the lower ends of the guide plates 13 are inserted into the corresponding inclined insertion grooves 15.

When the float ball valve 10 senses that the water level in the water tank 9 is too low, the valve in the water inlet pipe 8 is opened, and water is added into the water tank 9. After the float ball valve 10 senses that the water level in the water tank 9 reaches a high water level, the valve in the water inlet pipe 8 is closed.

[0022] Further, the rice steaming box cabinet 1 is connected with an exhaust hole 5, and the exhaust hole 5 is communicated with the rice steaming chamber. The steam flows upward to the exhaust hole 5 and is discharged.
