Description

Technical Field

[0001] The utility model belongs to the technical field of electric rice steamers, in particular to an electric rice steamer with a steam distribution system. Background Art

[0002] Electric rice steamers heat food to create steam, offering a powerful pure steaming function. They can quickly steam vegetables, rice, soup, and other dishes, while also offering precise temperature control, nutrient retention, lipid and salt reduction, and preservation of the original flavor and umami of food. However, in existing electric rice steamers, steam flows from the bottom to the top of the trays, resulting in higher temperatures on the bottom tray and lower temperatures on the upper trays, absorbing less heat. This results in uneven heating of the food. This frequently requires opening the door to remove cooked food from the lower tray and then moving the upper tray to the lower tray for continued steaming. Furthermore, existing electric rice steamers can only steam the same type of food on all trays at the same time, making it difficult to steam foods of different cooking times and temperatures simultaneously.

[0014] like Figure 1 As shown, an electric rice steaming box with a steam distribution system includes a box body 1, a rice steaming chamber 2, a steam generating chamber 3, and a steam flow channel 4 are provided in the box body 1, the rice steaming chamber 2 is located above the steam generating chamber 3, a heater 5 is installed in the steam generating chamber 3, a partition 6 is provided between the rice steaming chamber 2 and the steam generating chamber 3, a plurality of steam holes 7 are provided on the partition 6, a plurality of rice steaming trays 8 are sequentially provided in the rice steaming chamber 2 from bottom to top, both sides of the rice steaming tray 8 are respectively placed on a bracket 9, the bracket 9 is fixedly connected to the inner wall of the box body 1, and an air distribution layer 10 is formed between two adjacent rice steaming trays 8. The lower end of the housing 4 is connected to the steam generation chamber 3. The steam flow channel 4 is separated from the rice steaming chamber 2 by a vertical partition 6. The vertical partition 6 is provided with a plurality of communication openings 11, which correspond to the air distribution layer 10. The air distribution layer 10 is connected to the steam flow channel 4 through the corresponding communication openings 11. The steam flow channel 4 is provided with a plurality of guide plates 12, which correspond one to each of the communication openings 11. The middle portion of the guide plates 12 is mounted within the steam flow channel 4 via a rotating shaft 13. The rotating shaft 13 is driven by a motor located outside the housing 1. The air distribution layer 10 is provided with a plurality of temperature sensors 14. The heater 5 in the steam generation chamber 3 heats water to form high-temperature steam. Some of the steam enters the rice steaming chamber 2 through the steam holes 7, heating the bottommost rice steaming plate 8. The remaining steam enters the steam flow channel 4, forming high-temperature and high-pressure steam. The high-temperature and high-pressure steam enters the air distribution layer 10 through the communication openings 11, heating the upper and lower rice steaming plates 8. By rotating the guide plate 12 , the steam flux in the steam flow channel 4 can be adjusted, thereby guiding the steam into the corresponding air distribution layer 10 , thereby achieving the purpose of individually controlling the temperature of each air distribution layer 10 .

[0015] Furthermore, an air guide structure is installed within the air distribution layer 10. The air guide structure includes two air guide plates 15, forming an air guide channel 16 between the two air guide plates 15. The two air guide plates 15 are connected by a linkage plate 17, each hinged to the air guide plates 15 at both ends. One end of the air guide channel 16 is adjacent to the communication port 11. The middle portion of the air guide plate 15 is rotatably mounted within the steaming chamber 2 via a connecting shaft 18. The connecting shaft 18 is rotatably connected to the housing 1. One of the connecting shafts 18 extends outside the housing 1 and is connected to a rotating cap. The air guide structure can change the direction of steam flow within the air distribution layer 10. Continuous adjustment of the air guide structure can ensure a uniform temperature within the air distribution layer 10.

[0016] Furthermore, a pressure sensor 19 is installed within the communication port 11, and at least three temperature sensors 14 are installed within the air distribution layer 10, with the three temperature sensors 14 being sequentially arranged within the air distribution layer 10. The pressure sensor 19 can sense the airflow pressure within the corresponding communication port 11, providing parameters for the steam entering the air distribution layer 10, facilitating control of the corresponding guide plate 12 to adjust the air intake. The temperature sensor 14 can sense temperature data at different locations within the air distribution layer 10, facilitating control of the air guide structure to change the flow direction of steam entering the air distribution layer 10, thereby preventing uneven heating of the rice steaming tray 8 due to long-term overheating in a certain area of ​​the air distribution layer 10.

[0017] Furthermore, a movable cover 20 is placed on the partition 6. The movable cover 20 is provided with a plurality of docking holes 21, which correspond one to one with the steam holes 7. A push rod 22 is fixedly connected to the movable cover 20, and one end of the push rod 22 extends outside the box body 1 and is connected to a handle 26. By pulling the movable cover 20 with the handle 26, the docking holes 21 are staggered with the corresponding steam holes 7, thereby controlling the flow of steam entering the bottom layer below the rice steaming tray 8.

[0018] Furthermore, a condensation chamber 23 is provided above the steam generating chamber 3. The upper end of the steam flow channel 4 is connected to the condensation chamber 23, and a water receiving tray 24 is placed in the condensation chamber 23. The condensed water formed by the small amount of steam at the upper end of the steam flow channel 4 when it cools and condenses drips into the water receiving tray 24 for collection. This reduces the condensed water from directly flowing back from the steam flow channel 4 and affecting the rotation of the guide plate 12. It also reduces the condensed water from entering the air distribution layer 10 through the communication port 11 and affecting the food in the rice steaming tray 8.

[0019] Furthermore, a plurality of condensation columns 25 are provided in the condensation chamber 23 , the condensation columns 25 are fixedly connected to the housing 1 , and the condensation columns 25 are located above the water receiving tray 24 . The condensation columns 25 facilitate the condensation water to drip into the water receiving tray 24 .

[0020] It is worth mentioning that the technical features such as heaters and motors involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional options in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.

[0021] The above describes in detail the preferred specific embodiments of the present invention. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of existing technologies should be within the scope of protection determined by the claims.
