Description

Technical Field

[0001] The invention relates to the technical field of electric rice cookers, in particular to a full-automatic cooking pot structure. Background Art

[0002] With the development of society, people's living habits and living conditions have changed a lot, the pace of life is getting faster and faster, a large number of pre-prepared foods make it convenient for people to prepare dishes as soon as possible after work, but cooking is indeed a relatively lagging problem. Generally, it takes people about an hour to cook. If you make an appointment before work, you need to wash the rice in advance. Because the soaked rice is easy to deteriorate in hot weather and has a bad taste, especially in the southwest of my country, there is a habit of eating "raw steamed rice", which requires the rice to be steamed and soaked for many times, which is very inconvenient for modern people.

[0003] The automatic rice washing machine on the market, such as the disclosed Chinese patent CN202323298783, can only filter the rice after soaking, but does not have the function of washing. The existing electric rice cookers and other similar products mainly use the rice basket (liner) to be suspended, or the rice basket to be lifted and lowered to separate the rice from the water to achieve the purpose of steaming. This separation method requires accurate control of the water level and the amount of rice, which is not very convenient to use, and it is also impossible to steam and cook for many times, which also leads to a more complicated structure of the electric rice cooker and a higher overall cost. In addition, due to the hardening of the rice grains and the lack of steam holes, the phenomenon of undercooked and partially raw rice is caused, so the prior art needs to be improved and developed. Summary of the invention

[0004] The purpose of the present invention is to provide a fully automatic cooking pot structure with reasonable structure, convenient use and uniform cooking in view of the defects and shortcomings of the prior art.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: The fully automatic cooking pot of the present invention comprises an outer pot body, an inner pot body and a pot cover, wherein the pot cover is provided with a lifting screw rod which can be inserted into the inner pot body and rotated, and a detachable stirring head is connected to the bottom of the lifting screw rod, and the lifting screw rod can drive the stirring head to be lifted and rotated independently, and can also rotate during the lifting process. There is also an inner pot body with a mesh at the bottom, the bottom of the inner pot body is a waterproof sealing structure, there is a drain port at the bottom of the inner pot body, and one or more water inlets are arranged on the inner pot body.

[0006] According to the above scheme, further, the drain outlet at the bottom of the inner pot body is connected to the drain outlet of the outer pot body through a pipeline, and a drain valve and a return elbow are arranged in the middle of the pipeline.

[0007] According to the above solution, the water inlet on the inner pot body is connected to the water inlet on the outer pot body through a pipeline, and a water inlet valve is arranged in the middle of the pipeline.

[0008] According to the above solution, a flow meter is also connected to the water inlet valve.

[0009] According to the above solution, an overflow port is provided on the upper part of the inner pot body, and the overflow port is connected to the front part of the return elbow through a pipe, so as to prevent steam from escaping from the overflow port when the water in the pot boils.

[0010] According to the above scheme, a certain space is left between the bottom of the inner pot body and the bottom of the inner pot, which can ensure that the water maintains a certain distance from the bottom of the inner pot when boiling, preventing the rice grains at the bottom from being soaked in water for a long time during steaming and causing the bottom to become mushy.

[0011] According to the above solution, an elastic sealing ring is provided at the connection between the inner pot body and the inner pot at the top, and the elastic sealing ring can prevent steam from overflowing from the connection when the water in the pot boils.

[0012] According to the above solution, at least one sliding keyway is provided on the lifting screw, and the keyway pin corresponding to the keyway is designed as one piece with the rotating gear and can slide along the keyway on the lifting screw together.

[0013] According to the above solution, the lifting and lowering of the lifting screw is controlled by a lifting gear, and the lifting gear is composed of a worm gear with a concave shape in the middle.

[0014] According to the above solution, a rice bin and a rice bin baffle are arranged in the pot cover.

[0015] According to the above scheme, a rice bin motor and a rice bin slider are also provided in the pot cover. The rice bin motor can push the slider to open the rice bin baffle and push the rice into the inner pot through the rice bin motor screw.

[0016] According to the above scheme, one of the working processes of a fully automatic steam cooking pot provided by the present invention is: the cooking end time is set in advance at any time, and before going home, the fully automatic steam cooking pot automatically pushes the rice into the inner pot in multiple times according to the required amount at the scheduled time before arriving home, and the flow meter controls the water inlet valve to open according to the amount of water required for washing the rice, the lifting motor rotates and the rotating motor starts at the same time, and the stirring rod stirs the rice grains evenly and distributes them to the inner pot while descending, and washes at the same time, and the drain valve opens after the scheduled time, and after multiple washing cycles, the drain valve is closed, and the controller opens the water inlet valve to control the water inlet to about one centimeter under the bottom of the inner pot. At the same time, the controller controls the heating plate to work, and the steam sensor starts counting when it detects that the water is boiling. When the scheduled time is reached, the heating plate stops working, the water inlet valve opens, and the controller controls The amount of water inlet makes the rice grains in the inner pot soaked in water, and the stirring rod stirs left and right for several weeks and then stops rotating. After soaking for a predetermined time, the drain valve opens again, and the drain valve closes after the predetermined time. The controller opens the water inlet valve to control the water inlet to about one centimeter below the bottom of the inner pot. At the same time, the controller controls the heating plate to work, the lifting motor rotates and the rotating motor starts at the same time. The stirring rod breaks up the rice grains while descending. After several rotations, it stops rotating, the stirring rod is lifted vertically, and the rotating motor rotates the stirring rod again at a smaller angle, then vertically downward, and lifts it up after reaching the lowest end. This cycle continues until the stirring rod stops after one rotation, leaving evenly dispersed steam holes on the half-cooked loose rice. The heating plate is closed after the predetermined time. This cycle can be repeated many times. When the predetermined number of times is reached, it stops working and the steaming is finished.

[0017] According to the above scheme, the present invention can achieve the following beneficial effects: It truly realizes fully automatic operation and does not require advance material preparation. The rice bin can store rice grains for many days. The water inlet is directly connected to the municipal pipe network, and the wastewater is directly discharged into the wastewater pipe. The cooked rice will not only not be undercooked but also have distinct grains. The inner pot can also be used as a steamer alone, realizing dual uses of one pot. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the lifting gear 102A that controls the lifting and lowering of the lifting screw 102 adopts a concave structure in the middle to ensure a close fit with the lifting screw 102. In this embodiment, a form similar to a worm gear and a worm is adopted, which not only fits tightly but also has a self-locking function. There is also an inner pot 116 with a mesh at the bottom inside the inner pot body 115. The bottom of the inner pot body 115 is a waterproof sealing structure. There is a drain port 127 at the bottom of the inner pot body 115. A water inlet 126 or multiple water inlets are provided on the inner pot body 115. A water inlet valve 107 and a flow meter 106 are connected between the water inlet 126 and the water inlet 112 of the outer pot body 100. The drain port 127 at the bottom of the inner pot body 115 is connected to the drain port 112 of the outer pot body 100. 113 is connected by a pipeline, a drain valve 108 and a return elbow 129 are arranged in the middle of the pipeline, an overflow port 119 is arranged on the upper part of the inner pot body 115, and the overflow port 119 is connected to the front part of the return elbow 129 through a pipeline, which can prevent steam from overflowing after the water is boiled. A space of about 3 cm is left between the inner pot body 115 and the inner pot 116, and an elastic sealing ring 117 is arranged at the connection between the inner pot body 115 and the inner pot 116 at the top, a rice bin 120 and a rice bin baffle 121 are arranged in the pot cover 128, and a rice bin motor 122 and a rice bin slider 123 are also arranged, and the rice bin motor 122 can push the slider 123 to open the rice bin baffle 121 and push the rice into the inner pot 116 through the rice bin motor screw 125.

[0022] By adopting the above scheme, the working process of the fully automatic cooking pot provided by the present invention is as follows: the cooking end time can be set in advance at any time, and the fully automatic cooking pot automatically pushes the rice into the inner pot 116 in multiple times according to the required amount at the preset time before returning home, the flow meter 106 controls the water inlet valve 107 to open according to the required water amount for washing rice, the lifting motor 105 rotates and the rotating motor 103 is started, the stirring rod 101 stirs the rice grains evenly and distributes them to the inner pot 116 while descending, and washes the rice at the same time, and the drain valve 108 is closed after the preset time. After multiple washing cycles, the drain valve 108 is closed, and the controller 109 opens the water inlet valve 107 to control the water inlet to about one centimeter below the bottom of the inner pot 116. At the same time, the controller 109 controls the heating plate 111 to work. When the steam sensor 130 detects that the water is boiling, it starts counting. When the predetermined time is reached, the heating plate 111 stops working, the water inlet valve 107 is opened, and the controller 109 controls the water inlet to make the rice grains in the inner pot 116 soaked in water. After soaking for a predetermined time, the drain valve 108 is opened again, and the water is drained after the predetermined time. The valve 108 is closed, and the controller 109 opens the water inlet valve 107 to control the water inlet to about one centimeter below the bottom of the inner pot 116. At the same time, the controller 109 controls the heating plate 111 to work, the lifting motor 105 rotates and the rotating motor 103 is started. The stirring rod 101 breaks up the rice grains while descending. After several rotations, the stirring rod 101 stops rotating, and the stirring rod 101 is lifted vertically.
