Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0043] The first embodiment of the present application is as follows:

[0044] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a rice steaming cabinet for removing pesticide residues and heavy metals with low sugar according to the first embodiment of the present invention.

[0045] The present invention provides a rice steaming cabinet for removing pesticide residues and heavy metals with low sugar, comprising a rice steaming cabinet body 101, a perforated rice steaming tray 102, a water level sensor 103, a circulating water pump 104, a circulating water pipe 105, a spraying tray 106 and a mat 107. The rice steaming cabinet body 101 has a cooking chamber 108 and a water heating chamber 109. Through the foregoing solution, the existing rice cooking technology uses a non-perforated steaming tray to put rice and water and then heats to steam out rice without any filtration, resulting in uneven hardness of the cooked rice. Now, excessive use and over-reliance on pesticides and fertilizers in rice cultivation make the rice contain pesticide residues and heavy metals, thus causing the risk of residual pesticide residues and heavy metals. It can be understood that the foregoing solution can be used in cases where it is necessary to remove pesticide residues and heavy metals in rice.

[0046] In this embodiment, the rice is laid flat in the perforated rice steaming tray 102, and through the intelligent fully automatic rice washing, automatic discharge of the rice washing water, automatic water inlet for cooking rice, decomposition of the sugar and fat in the rice, decomposition of the pesticide residues and heavy metals in the rice, automatic discharge of the unhealthy rice cooking water, automatic water inlet for cooling and flushing the viscous starch juice and residues in the rice, automatic discharge of the flushing wastewater, and automatic water inlet for steaming the rice until cooking is completed.

[0047] Among them, the perforated rice steaming tray 102 is arranged inside the rice steaming cabinet body 101 and on both sides of the rice steaming cabinet body 101. The water level sensor 103 is arranged inside the rice steaming cabinet body 101 and on one side of the rice steaming cabinet body 101. The circulating water pump 104 is arranged under the rice steaming cabinet body 101 and at the bottom of the rice steaming cabinet body 101. The circulating water pipe 105 is respectively connected to the circulating water pump 104 and the rice steaming cabinet body 101. The circulating water pipe 105 is located on the side of the circulating water pump 104 close to the rice steaming cabinet body 101. The spraying tray 106 is arranged in the upper part inside the rice steaming cabinet body 101 and at the upper part inside the rice steaming cabinet body 101. The perforated rice steaming tray 102 is arranged inside the rice steaming cabinet body 101, and rice can be spread flat on the perforated rice steaming tray 102. The water level sensor 103 is arranged inside the rice steaming cabinet body 101, and the water level inside the rice steaming cabinet body 101 can be controlled through the water level sensor 103. The circulating water pump 104 is arranged on the rice steaming cabinet body 101, and the fluid in the rice steaming cabinet body 101 can be discharged or introduced through the circulating water pump 104. The spraying tray 106 is arranged in the upper part inside the rice steaming cabinet body 101. The circulating water pipe 105 is respectively connected to the circulating water pump 104 and the rice steaming cabinet body 101. The circulating water pipe 105 can connect the circulating water pump 104 and the rice steaming cabinet body 101. Water can be sprayed into the rice steaming cabinet body 101 through the spraying holes on the spraying tray 106. Thus, when steaming rice, the rice is spread flat and put into the perforated rice steaming tray 102, the circulating water pump 104 is started to inject clean water into the rice steaming cabinet body 101, so as to wash the rice on the perforated rice steaming tray 102. After the rice washing is completed, the circulating water pump 104 is started for drainage, and then the circulating water pump 104 is turned on to introduce water into the heating system (the heating system is described in the prior art CN212015285U and will not be elaborated here) in the rice steaming cabinet body 101 to heat it to the boiling state. The spraying tray 106 and the circulating water pump 104 are started, and the water level is intelligently controlled through the water level sensor 103, so that the rice is boiled in a boiling water cycle in the rice steaming cabinet body 101 to decompose sticky starch juice. During the boiling water cycle, starch and boiling water are mixed to form a colloid, which adsorbs and removes pesticide residues and heavy metals in the rice. After the rice reaches seven or eight-tenths cooked, the circulating water pump 104 is started to discharge the cooking rice wastewater. At this time, the heating system is automatically shut down. The circulating water pump 104 is started and water enters the water heating cavity 109 of the rice steaming cabinet. The spraying tray 106 and the circulating water pump 104 are started, and the rice is washed by cold water circulation. After the washing is completed, the drainage program of the circulating water pump 104 is started to automatically discharge the residual starch and residue wastewater. Again, water is introduced into the water heating cavity 109 of the rice steaming cabinet through the circulating water pump 104 to heat it to the boiling state for the process of steaming rice.After the rice steaming is completed, the heating system is automatically shut down and enters the heat preservation function, and the cooking is completed. Thus, through the circulating water pump 104 and the spraying tray 106, the rice is steamed and rinsed at a specific time, so that the pesticide residues and heavy metals in the rice can be adsorbed and removed, thereby providing guarantee for food safety.

[0048] Secondly, the mat 107 is arranged on the perforated rice steaming tray 102. Through the mat 107, the rice can be prevented from leaking during washing, cooking and rice steaming. The holes of the perforated rice steaming tray 102 are relatively large to facilitate the smoothness of the multi-layer filter layer. The mat 107 is of a porous design, and the holes are smaller than the size of the rice grains.

[0049] Finally, the steaming cavity 108 is located at the upper inner part of the rice steaming cabinet body 101; the water heating cavity 109 is located at the lower inner part of the rice steaming cabinet body 101. The rice steaming cabinet body 101 has the steaming cavity 108 and the water heating cavity 109. The rice is steamed in the steaming cavity 108, and the water is heated in the water heating cavity 109.

[0050] When using the rice steaming cabinet for low sugar removal of pesticide residues and heavy metals in this embodiment, during rice steaming, the rice is laid flat and placed in the perforated rice steaming tray 102, and the circulating water pump 104 is started to inject clean water into the rice steaming cabinet body 101, so as to wash the rice in the perforated rice steaming tray 102. After the rice washing is completed, the circulating water pump 104 is started to drain the water, and then the circulating water pump 104 is opened to introduce the water into the heating system in the rice steaming cabinet body 101 to be heated to the boiling state. The spraying tray 106 and the circulating water pump 104 are started, and the water level is intelligently controlled through the water level sensor 103, so that the rice is boiled in the rice steaming cabinet body 101 by boiling water circulation to decompose viscous starch juice. During the boiling water circulation process, the starch is mixed with the boiling water to form a colloid, adsorbing and removing the pesticide residues and heavy metals in the rice. After the rice reaches seven or eight minutes of doneness, the circulating water pump 104 is started to discharge the rice cooking wastewater. At this time, the heating system is automatically shut down, and the circulating water pump 104 is started to make the water enter the water heating cavity 109 of the rice steaming cabinet. The spraying tray 106 and the circulating water pump 104 are started, and the rice is flushed by cold water circulation. After the flushing is completed, the drainage program of the circulating water pump 104 is started to automatically discharge the residual starch and the residue wastewater. Again, the circulating water pump 104 is used to introduce the water into the water heating cavity 109 of the rice steaming cabinet to be heated to the boiling state for the rice steaming process. After the rice steaming is completed, the heating system is automatically shut down and enters the heat preservation function, and the cooking is completed. Thus, through the circulating water pump 104 and the spraying tray 106, the rice is steamed and rinsed at a specific time, so that the pesticide residues and heavy metals in the rice can be adsorbed and removed, thereby providing guarantee for food safety.

[0051] The second embodiment of the present application is as follows:

[0052] Based on the first embodiment, please refer to Figure 2 , Figure 2 which is a step diagram of the method for cooking rice in a rice cooker with low sugar and removal of pesticide residues and heavy metals according to the second embodiment of the present invention.

[0053] The present invention provides a method for cooking rice in a rice cooker with low sugar and removal of pesticide residues and heavy metals, comprising the following steps:

[0054] S201: Spread the rice flatly in the perforated rice steaming tray 102;

[0055] S202: The rice cooker controls full-automatic rice washing and automatically discharges the rice washing water;

[0056] S203: The rice cooker automatically fills with water to cook the rice, decomposes the sugar in the rice, decomposes the pesticide residues and heavy metals in the rice, and automatically discharges the unhealthy rice cooking water;

[0057] S204: The rice cooker automatically fills with water to cool and wash away the viscous starch juice and residues in the rice;

[0058] S205: The rice cooker controls automatic rice steaming;

[0059] S206: The rice cooker controls automatic cleaning of the rice cooker.

[0060] Further, lay the rice flat in the perforated rice steaming tray 102 (a layer of the environmentally friendly water-draining padding 107 is laid in the perforated rice steaming tray 102). The intelligent software controls full-automatic rice washing and automatic drainage of the rice washing water: Start the water injection program, open the water inlet valve. The water inlet valve is arranged in the water heating cavity 109, and inject clear water. At this time, the spray tray 106 and the circulation water pump 104 start to work. The water outlet end of the circulation water pump 104 is connected to the spray tray 106 through a pipeline to carry out the circulating rice washing work. At this time, the heating system does not start. After the rice washing work is completed, start the drainage program, open the drainage valve to automatically drain the rice washing water. The drainage valve is arranged at the bottom of the water heating cavity 109; The intelligent software controls automatic water inlet for cooking rice, decomposes the sugar in the rice, decomposes the pesticide residues and heavy metals in the rice, and automatically drains the unhealthy rice cooking water: Start the water injection program, open the water inlet valve. The water enters the water heating cavity 109 of the rice steaming cabinet through the water inlet valve and is heated to the boiling state. Start the spray tray 106 and the circulation water pump 104. The water inlet end of the circulation water pump 104 is connected to the water heating cavity 109 of the rice steaming cabinet through a pipeline, and the water outlet end of the circulation water pump 104 is connected to the spray tray 106 through a pipeline. The water level sensor 103 intelligently controls the water level to carry out boiling water circulation for cooking rice, decomposes the viscous starch juice to achieve the sugar-lowering effect, removes pesticide residues and heavy metals during cooking, and the starch forms a colloid after mixing with boiling water, which can adsorb and remove the pesticide residues and heavy metals in the rice. When the rice is cooked to seven or eight-tenths done, the whole rice cooking is completed, start the drainage program, open the drainage valve to automatically drain the rice cooking wastewater. At this time, the heating system automatically shuts down; Automatically inlet water for cooling and flushing the viscous starch juice and residues in the rice: Start the water injection program, open the water inlet valve. The water enters the water heating cavity 109 of the rice steaming cabinet through the water inlet valve. Start the spray tray 106 and the circulation water pump 104. The water inlet end of the circulation water pump 104 is connected to the water heating cavity 109 of the rice steaming cabinet through a pipeline, and the water outlet end of the circulation water pump 104 is connected to the spray tray 106 through a pipeline. The water enters the water heating cavity 109 of the rice steaming cabinet through the water inlet valve to carry out the cold water circulation for flushing the rice. If not flushed, a part of the decomposed starch and residues still adhere to the surface of the rice. During the cold water cooling process, the starch quickly forms crystals, and the pesticide residues and heavy metals also adhere to the starch. Circulating flushing removes these attachments, achieving the effects of reducing sugar, reducing fat, removing pesticide residues and heavy metals.During this process, the heating system does not start. After the flushing work is completed, the drainage program is started, and the drainage valve is opened to automatically discharge the residual starch and the wastewater of the residues. The intelligent software controls the automatic rice steaming: water enters the water heating chamber 109 of the rice steaming cabinet again through the water inlet valve and is heated to the boiling state to carry out the rice steaming process. When the rice steaming is completed according to the system settings, the heating system is automatically shut down and enters the heat preservation function, and the whole cooking is completed. The intelligent software controls the automatic cleaning function: water enters the water heating chamber 109 of the rice steaming cabinet through the water inlet valve, and the spray tray 106 and the circulating water pump 104 are enabled again. The water inlet end of the circulating water pump 104 is connected to the water tank of the rice steaming cabinet through a pipeline, and the water outlet end of the circulating water pump 104 is connected to the spray tray 106 through a pipeline to carry out the circulating cleaning of the cabinet body. After the cleaning is completed, the drainage program is started, and the drainage valve is opened to automatically discharge the sewage and automatically shut down the circulating cleaning function. The intelligent software controls the reservation function: the reservation function can be set, and the cooking time can be reserved and adjusted at will. The water level sensor in the rice steaming cabinet has the functions of automatic water replenishment and water overage protection during rice washing, cooking, draining, and steaming, and has the functions of automatic water replenishment and automatic drainage monitoring. The low-sugar rice steaming cabinet for intelligent fully automatic rice washing, cooking, draining, and steaming: intelligent fully automatic rice washing, automatic discharging of the rice washing water, automatic water inlet for cooking, decomposition of the sugar and fat in the rice, decomposition of the pesticide residues and heavy metals in the rice, automatic discharging of the unhealthy cooking water, automatic water inlet for cooling and flushing the viscous starch juice and residues in the rice, automatic discharging of the flushing wastewater, and automatic water inlet for rice steaming until the cooking is completed. There is no need for manual rice washing and manual water addition anymore, and all processes are completed automatically. The cooked rice has plump grains, distinct grains, is environmentally friendly, healthy, has a good taste, reduces waste, and saves labor hours.

[0061] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention.
