Description

TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, and in particular to a multifunctional grain germination device. BACKGROUND

[0002] With the continuous improvement of living standards, people's pursuit of food nutrition and taste is also getting higher and higher. Germinated grains refer to grains that have been germinated to an appropriate length of sprouts, mainly composed of two parts of young sprouts and aleurone layer, which are rich in nutrients beneficial to the human body. For example, in brown rice, part of the protein in germinated brown rice is decomposed into amino acids, while it also retains rich vitamins, minerals, and dietary fiber nutrients such as gamma-aminobutyric acid and inositol hexaphosphate. However, the germination of grains has very high requirements for temperature and humidity, and existing kitchen cooking utensils cannot be directly used for germination. Therefore, there are currently kitchen utensils on the market that are used solely for grain germination, and the grains are transferred to a traditional electric rice cooker for cooking after germination. However, due to limited kitchen space, there is often not enough space to accommodate multiple kitchen utensils, and existing grain germination devices also have some problems.

[0003] Specifically, early grain germination appliances immerse grains (such as brown rice) in a closed container for a long time to maintain the water temperature required for grain germination and allow them to germinate. Due to the long germination time of grains, long-term immersion in a closed container can severely affect the germination rate of brown rice due to low oxygen content in the container. In addition, after long-term immersion in a closed container, it is also prone to problems such as off-flavor or sliminess. Some people propose replacing the soaking water multiple times to avoid spoilage, but this method not only causes operational complexity and difficulty in automation, but also results in the loss of water-soluble useful components such as gamma-aminobutyric acid produced during germination after frequent water changes. At the same time, it still has the problem of low brown rice germination rate due to low oxygen content in the container.

[0004] To solve the problem of oxygen content during grain germination, Chinese patent CN118339977A proposes a brown rice germination device that fills the inner cavity of a hollow heat-insulating float with hydrogen peroxide. When the nano-manganese dioxide layer as a catalyst comes into contact with hydrogen peroxide, hydrogen peroxide rapidly decomposes into water and oxygen, which is discharged into the water body through the oxygen channel. This oxygenation method not only has a complex structure, but also poses a significant safety risk for brown rice germination because both hydrogen peroxide and manganese dioxide are non-edible chemicals, making it difficult to apply in practice. In addition, the brown rice in this scheme is still immersed in water for a long time, and the problems of off-flavor and sliminess caused by long-term immersion cannot be solved. SUMMARY

[0005] The present application overcomes the deficiencies of the prior art and provides a multifunctional grain germination device.

The air exchange channel is formed in the container cover. The carrier cavity is formed between the container cover and the carrier.

[0010] According to an embodiment of the present application, the container cover comprises a cover body and an inner cover plate arranged on the inner side of the cover body and facing the carrier. A cover body accommodating cavity is formed between the cover body and the inner cover plate. The oxygen increasing pipeline of the oxygen increasing assembly penetrates the inner cover plate and extends into the cover body accommodating cavity. After extending in the cover body accommodating cavity, the oxygen increasing pipeline is assembled with the air outlet on the inner cover plate to communicate with the carrier cavity.

[0016] According to an embodiment of the present application, the multifunctional grain germination device further comprises a shell, and the container body, the pump body assembly and the temperature control assembly are all accommodated in the shell, and the bottom of the shell is provided with a heat dissipation hole; the multifunctional grain germination device further comprises a heat dissipation fan, which is detachably fixed to the inner bottom wall of the shell and opposite to the temperature control assembly.

[0017] According to an embodiment of the present application, the carrier is an inner container with a drain hole in the bottom, and the liquid guide pipe is integrally formed on the outer bottom wall of the inner container around the drain hole.

[0018] Alternatively, the upper end of the liquid guide pipe is sealingly connected to the outer bottom wall of the inner container around the drain hole.

[0019] According to an embodiment of the present application, the carrier is a steamer placed in the container body, and the liquid guide pipe is integrally formed on or sealingly connected to the bottom wall of the steamer around the drain hole.

[0020] The present application also provides another multifunctional grain germination device, which comprises a container, a carrier, a liquid guide pipe, a pump body assembly and a temperature control assembly. The container comprises a container body and a container cover, and the container cover is provided with a first air exchange channel which can be communicated or blocked. The carrier is sealingly accommodated in the container body and has a drain hole in the bottom, and the bottom of the carrier does not abut against the inner bottom wall of the container body, and the carrier is surrounded by a carrier cavity above which the first air exchange channel is communicated. The upper end of the liquid guide pipe is sealingly connected to the bottom of the carrier and surrounds the drain hole, and the lower end of the liquid guide pipe extends to the inner bottom wall of the container body and forms a water flow channel with the inner bottom wall of the container body; the container body is provided with a second air exchange channel which can be communicated or blocked. The pump body assembly is arranged on the container cover and communicates with the carrier cavity, and when the first air exchange channel is blocked and the second air exchange channel is communicated, the pump body assembly pumps air to the carrier cavity so that the liquid in the container body enters the carrier cavity through the liquid guide pipe; when the first air exchange channel is opened or the pump body assembly pumps air, the liquid falls back to the container body through the liquid guide pipe.

[0025] In summary, the multifunctional grain germination device provided by the application has the following advantages: the lower end of the liquid guide and the inner bottom wall of the container body form a water flow passage below the liquid level, and the outer peripheral wall of the liquid guide, the bottom wall of the carrier and the inner wall of the container body form a pressure regulating cavity. The pump body assembly supplies or extracts air into the pressure regulating cavity, so that the liquid enters the carrier cavity to soak the grains. After the soaking time meets the requirements, the pump body assembly extracts air, and the liquid falls back to the container body under the action of gravity. This intermittent soaking method meets the moisture requirements of grain germination, and avoids problems such as odor, stickiness and deterioration caused by long-term soaking. In addition, the air exchange passage is formed on the container cover, so that when the pump body assembly supplies air into the pressure regulating cavity, the liquid enters the carrier cavity at the same time, and the turbid gas in the carrier cavity is discharged through the air exchange passage; and when the liquid falls back during air extraction, external air is sucked through the air exchange passage to increase oxygen.

[0026] Further, since the carrier and the liquid guide are separable, the multifunctional grain germination device can have a second working mode and a third working mode after the two are removed or only the liquid guide is removed, thereby realizing the collection of multiple food processing functions. Further, the multifunctional grain germination device provided by the application further comprises a temperature control assembly, which has two modes of heating and cooling, and quickly adjusts the temperature to accurately control the liquid temperature at different germination stages.

[0045] Example 1

[0046] like Figures 1 to 12 As shown, the multifunctional grain germination device provided in this embodiment includes a container 1, a carrier 2, a liquid guide pipe 3, a pump assembly 4, and a temperature control assembly 5. The container 1 includes a container body 11 and forms a ventilation channel 120. The carrier 2 is sealed and housed within the container body 11 and has a drainage hole 21. The bottom of the carrier 2 does not abut against the inner bottom wall of the container body 11, and a carrier cavity 20 communicating with the ventilation channel 120 is formed above the carrier 2. The upper end of the liquid guide pipe 3 is sealed and connected to the bottom of the carrier 2 and surrounds the outer periphery of the drainage hole 21. The lower end of the liquid guide pipe 3 extends towards the inner bottom wall of the container body 11 and forms a water flow channel 30 between it and the inner bottom wall of the container body 11. A pressure regulating cavity 10 is formed between the outer periphery of the liquid guide pipe 3, the bottom wall of the carrier 2, and the inner wall of the container body 11. The pump assembly 4 is disposed outside the container body 11, and its gas supply end 401 passes through the container body 11 or the carrier 2 to connect with the pressure regulating chamber 10. The pump assembly 4 supplies or draws gas into the pressure regulating chamber 10, and discharges or draws in external air to the carrier chamber through the ventilation channel 120. The temperature control assembly 5 is disposed on the outer bottom wall of the container body 11 to heat or cool the liquid inside the container body 11. In this embodiment, the carrier 2 and the liquid guide tube 3 are detachably disposed inside the container body 11. This arrangement allows the multifunctional grain germination device provided in this embodiment to have at least three cooking modes. When the carrier 2 and the liquid guide tube 3 are placed inside the container body 11, the multifunctional grain germination device is in the first working mode for grain germination or preservation. When both the carrier 2 and the liquid guide tube 3 are removed from the container body 11 and the pump assembly 4 stops working, the multifunctional grain germination device is in the second working mode for cooking rice. When only the liquid guide tube 3 is removed and the pump assembly 4 stops working, the multi-functional grain germination device is in the third working mode for food steaming. Specifically, the second working mode is the working mode of an existing rice cooker, while the third working mode is the working mode of an existing steamer; that is, the multi-functional grain germination device provided in this embodiment has three functions: germination and preservation, rice cooking, and steaming.

[0047] The following will combine Figures 1 to 9 This embodiment describes in detail the working principle of the multifunctional grain germination device in the first working mode for grain germination.

[0048] In the multifunctional cereal germination device provided in the embodiment, the water flow passage 30 formed at the bottom of the liquid guide tube 3 is sealed with liquid when in use. The water seal makes the pressure regulating cavity 10 formed between the outer peripheral wall of the liquid guide tube 3, the bottom wall of the carrier 2 and the inner wall of the container body 11 into a sealed chamber. When the pump body assembly 4 pumps air into the pressure regulating cavity 10, the pressure in the pressure regulating cavity 10 increases and forces liquid into the liquid guide tube 3 and gradually into the carrier cavity 20 to soak the cereal. After the soaking meets the set time, the pump body assembly 4 pumps air out, the pressure in the pressure regulating cavity 10 decreases, and the liquid falls back along the liquid guide tube 3 under the action of gravity, and the cereal germinates in a draining state. At the same time, fresh air from the outside enters the carrier cavity 20 through the air exchange passage 120, and the oxygen in the air gradually penetrates into the cereal to provide oxygen for the cereal germination in the draining state. After the draining germination meets the set time, the pump body assembly 4 is turned on again to pump air into the pressure regulating cavity 10, and the liquid enters the carrier cavity 20 again to replenish water for the cereal while discharging the turbid gas generated by the cereal germination in the carrier cavity 20 from the air exchange passage 120. After the replenishment meets the set time, air is pumped out to drain the cereal while introducing fresh air to increase oxygen.

[0049] In the embodiment, the cereal refers to unpolished rice, mung beans, soybeans, wheat and other edible cereals for human body.

[0050] In the embodiment, the container 1 further includes a container cover 12, which is detachably covered on the carrier 2, the air exchange passage is an air exchange opening formed on the container cover 12, and the carrier cavity 20 is formed between the container cover 12 and the carrier 2. In other embodiments, the air exchange passage can also be a gap between the container cover and the container body. Although the embodiment takes the container cover detachably covered on the carrier as an example, the present application does not make any limitation in this regard. In other embodiments, when the carrier is a steamer, the container cover can also be covered on the container body. In other embodiments, when the multifunctional cereal germination device is only used for cereal germination, the container can also not include a container cover, and the open end of the container body forms an air exchange passage.

[0051] In the embodiment, the liquid for soaking the cereal is water or water with added nutrients.

[0052] The multifunctional grain germination device provided by the embodiment can promote the circulation of liquid between the pressure regulating cavity 10 and the bearing cavity 20 through the pump body assembly 4 to realize the intermittent soaking of the grains. The soaking method can not only ensure the moisture required for grain germination, but also enable the grains to better contact with the air in the bearing cavity 20 during the draining germination process, thereby improving the germination rate and effectively inhibiting the odor and deterioration problems caused by long-term soaking in the existing germination method. In addition, more importantly, with the intermittent flow of the liquid, the bearing cavity 20 is synchronously aerated, the turbid gas generated during the soaking is discharged, and fresh air is introduced during the draining, thereby increasing the oxygen content in the bearing cavity 20 to improve the germination rate. To further improve the germination rate, the multifunctional grain germination device provided by the embodiment further comprises an oxygen increasing assembly 6, and the oxygen increasing pipeline 61 of the oxygen increasing assembly 6 is connected to the bearing cavity 20 to actively input gas into the bearing cavity 20 for oxygen increasing.

[0053] Specifically, as shown in Figure 4 、 Figure 5 and Figure 7 , the oxygen increasing assembly 6 is integrated with the pump body assembly 4, the pump body assembly 4 comprises a gas pump 41, a pressurizing pipeline 42 and a pressurizing electromagnetic valve 43, and the pressurizing electromagnetic valve 43 is connected to or blocks the pressurizing pipeline 42. The oxygen increasing assembly 6 comprises an oxygen increasing pipeline 61 connected to the gas pump and an oxygen increasing electromagnetic valve 62 connected to or blocking the oxygen increasing pipeline 61, and the oxygen increasing pipeline 61 is connected to the bearing cavity 20. For the electromagnetic valve, when it is opened, the pipeline where it is located is connected; correspondingly, when it is closed, the pipeline where it is located is blocked. During the soaking, the pressurizing electromagnetic valve 43 is opened and the oxygen increasing electromagnetic valve 62 is closed, the gas pump 41 pressurizes the pressure regulating cavity 10 through the pressurizing pipeline 42, so that the liquid enters the bearing cavity 20 through the liquid guide pipe 3. Then, the pressurizing electromagnetic valve 43 is closed to make the pressure regulating cavity 10 enter the pressure maintaining state, and the liquid still immerses the grains; at this time, the oxygen increasing electromagnetic valve 62 is opened, and the gas pump 41 inputs fresh air into the bearing cavity 20 through the oxygen increasing electromagnetic valve 62 and the oxygen increasing pipeline 61 to continuously or periodically increase the oxygen. After the immersion meets the set requirements, the pressurizing electromagnetic valve 43 is opened and the oxygen increasing electromagnetic valve 62 is closed, and the gas pump 41 pumps the pressure regulating cavity 10 through the pressurizing pipeline 42 and the pressurizing electromagnetic valve 43, so that the pressure in the pressure regulating cavity 10 decreases to realize the draining. After the draining is completed, the pressurizing electromagnetic valve 43 is closed and the oxygen increasing electromagnetic valve 62 is opened, and the gas pump actively increases the oxygen in the grains in the bearing cavity 20 in the draining state through the oxygen increasing electromagnetic valve 62; that is, the active oxygen increasing of the grains in the soaking state and the draining state is realized, thereby greatly improving the success rate of grain germination.

[0054] In this embodiment, the oxygenation component 6 is integrated into the pump body component 4 so that both can share a single air pump 41, significantly reducing material costs. However, the present invention does not limit this. In other embodiments, the oxygenation component can also be set independently of the pump body component. The oxygenation component includes an oxygenation pump and an oxygenation pipeline. In this case, the oxygenation pump can be turned on and off directly, without the need for an additional oxygenation solenoid valve. In other embodiments, the pump body component may also include an air pump with only air delivery function, a pressurization pipeline, and an exhaust solenoid valve. The exhaust solenoid valve is connected to the outside of the multifunctional grain germination device through a pipeline. During soaking, the air pump delivers air to the pressure regulating chamber through the pressurization pipeline, while during draining, the air pump stops working, and the exhaust solenoid valve discharges the gas in the pressure regulating chamber through the pressurization pipeline.

[0055] In this embodiment, a pressurizing port 110 is provided on the side wall of the container body 11. The gas supply end 401 of the pressurizing pipeline 42 on the pump assembly 4 is connected to the pressurizing port 110, through which gas is supplied to or drawn from the pressure regulating chamber 10. However, the present invention does not limit this in any way. In other embodiments, when the carrier is an inner liner with a pot rim, the pot rim of the carrier is sealed to the container body, and a pressurizing port is provided at the pot rim of the carrier. The gas supply end of the pressurizing pipeline is connected to the pressure regulating chamber through the pressurizing port.

[0056] like Figure 3 As shown, in this embodiment, the container lid 12 includes a lid body 121 and an inner cover plate 122 disposed inside the lid body 121 and facing the support member 2. A lid body receiving cavity 123 is formed between the lid body 121 and the inner cover plate 122. The oxygenation pipe 61 on the oxygenation assembly 6 passes through the inner cover plate 122 and extends into the lid body receiving cavity 123. After extending within the lid body receiving cavity 123, it is fitted with an air outlet 1220 on the inner cover plate 122 to communicate with the support cavity 20. This arrangement realizes the built-in layout of the oxygenation pipe 61 on the container lid 12, avoiding interference of the oxygenation pipe 61 with components such as the support member 2. However, the present invention does not impose any limitations on this. In other embodiments, when the support is an inner liner with drainage holes, the gas delivery end of the oxygenation pipeline can also penetrate the peripheral wall of the support to connect to the support cavity; for example, the oxygenation pipeline is built into the pressure regulating pipeline, and the gap between the oxygenation pipeline and the pressure regulating pipeline forms a pressure regulating gas delivery channel. The oxygenation pipeline follows the pressure regulating pipeline through the peripheral wall of the container body and then through the peripheral wall of the support. Alternatively, when the support is a steam rack, the gas delivery end of the oxygenation pipeline can also penetrate the peripheral wall of the container body above the support to connect to the support cavity.

[0057] In this embodiment, as Figure 6As shown, the carrier 2 is an inner container with a bottom having a draining hole 21, and the liquid guide tube 3 is integrally formed on the outer bottom wall of the inner container outside the periphery of the draining hole 21. However, the present application is not limited thereto. In other embodiments, the upper end of the liquid guide tube can also be sealingly connected to the outer bottom wall of the inner container outside the periphery of the draining hole by a sealing ring. Alternatively, in other embodiments, the carrier is a steamer placed in the container body, the edge of the steamer is embedded in the container body by a sealing ring to form a pressure regulating cavity, and the liquid guide tube is integrally formed on or sealingly connected to the bottom wall of the steamer outside the periphery of the draining hole.

[0058] For grains, in order to ensure the success rate of germination, it is necessary to soak them in a liquid at a specific temperature, such as a soaking temperature controlled at 20-40°C; and after the grains start to germinate, it is necessary to control the length of the sprouts to avoid excessive germination and loss of nutrients. Therefore, the present embodiment adds a temperature control assembly 5 outside the container body 11, which has two temperature control modes, i.e. it can heat the liquid in the container body 11 to meet the soaking temperature, and after the germination starts, it can quickly cool the liquid to accurately control the length of the sprouts. In the present embodiment, as shown in Figure 3 and Figure 5 The temperature control assembly 5 includes a semiconductor cooler (TEC) 51 and a heating disc 52. The semiconductor cooler 51 is arranged on the outer bottom wall of the container body 11, and the heating disc 52 is attached to the outer bottom wall of the container body 11 and surrounds the periphery of the semiconductor cooler 51. In the present embodiment, the heating disc 52 is used to heat the liquid in the container body 11 to meet the requirement of the soaking temperature before germination; and the semiconductor cooler 51 quickly lowers the temperature of the liquid after germination to slow down the germination rate and accurately control the length of the sprouts. However, the present application is not limited thereto.

[0059] For the semiconductor cooler, the cooling / heating state can be switched by changing the direction of the current. In other embodiments, the semiconductor cooler can also be in a heating state before germination, and the semiconductor cooler and the heating disc jointly heat the liquid; and after germination, the heating disc is quickly turned off, and the direction of the current of the semiconductor cooler is changed to quickly enter the cooling state. Since the soaking water temperature required for grain germination is not high, in other embodiments, when the semiconductor cooler has a larger heating power, the temperature control assembly can also only have a semiconductor cooler, as shown in Figure 10 The multifunctional grain germination device of the structure has the semiconductor cooler in a heating state before germination; and after germination, the direction of the current is quickly switched to make the semiconductor cooler enter the cooling state.

[0060] In the present embodiment, as shown in Figure 1 , Figure 2 and Figure 3As shown, the multifunctional grain germination device further comprises a housing 7, the container body 11, the pump body assembly 4 and the temperature control assembly 5 are all received in the housing 7, and the bottom of the housing 7 is formed with a heat dissipation hole 71 opposite to the temperature control assembly 5. Further, in the embodiment, the multifunctional grain germination device further comprises a heat dissipation fan 8, which is detachably fixed to the inner bottom wall of the housing 7 and opposite to the temperature control assembly 5 by fasteners, and the heat generated by the temperature control assembly 5 is discharged from the heat dissipation hole 71.

[0061] Figure 11 and Figure 12 are respectively structural schematic diagrams of the multifunctional grain germination device in the second working mode and the third working mode. In Figure 11 , the carrier 2 and the liquid guide pipe 3 are both removed from the container body 11, and the container body 11 becomes a rice cooker in the second working mode. In Figure 12 , only the liquid guide pipe 3 is removed, and the carrier 2 is still placed in the container body 11, which makes the multifunctional grain germination device in the third working mode, and the temperature control assembly 5 heats the water in the container body 11 to generate steam to steam the food on the carrier 2.

[0062] Embodiment Two

[0063] The embodiment is basically the same as embodiment one and its variations, and the difference lies in the structure, installation position and working chamber of the pump body assembly 4.

[0064] In embodiment one, the pump body assembly 4 realizes the circulation of liquid between the pressure regulating chamber and the carrier chamber by changing the pressure in the pressure regulating chamber, thereby realizing the germination or preservation of grains in the first working mode. In the embodiment, the pump body assembly 4 is arranged on the container cover 12, which realizes the circulation of liquid between the pressure regulating chamber and the carrier chamber by adjusting the pressure in the carrier chamber 20; that is, in the embodiment, the object of the pump body assembly 4 is the carrier chamber 20.

[0065] Specifically, as Figures 13 to 17As shown, the multifunctional cereal germination device provided by the embodiment includes a container 1, a carrier 2, a liquid guide pipe 3, a pump body assembly 4, and a temperature control assembly 5. The container 1 includes a container body 11 and a container cover 12, and the container cover 12 is formed with a first air exchange channel that can be communicated or blocked. The carrier 2 is sealingly accommodated in the container body 11 and has a draining hole 21, and the bottom of the carrier 2 does not abut against the inner bottom wall of the container body 11. An upper portion of the carrier 2 is surrounded by a carrier cavity 20 that communicates with the first air exchange channel. The upper end of the liquid guide pipe 3 is sealingly connected to the bottom of the carrier 2 and surrounds the outer periphery of the draining hole 21, and the lower end of the liquid guide pipe 3 extends toward the inner bottom wall of the container body 11 and forms a water flow channel 30 with the inner bottom wall of the container body 11. The container body 11 is formed with a second air exchange channel 110' that communicates with the inner cavity of the container body 11 and can be communicated or blocked. The pump body assembly 4 is arranged on the container cover 12 and communicates with the carrier cavity 20. When the first air exchange channel 120' is blocked and the second air exchange channel 110' is communicated, the pump body assembly 4 draws air from the carrier cavity to make the liquid in the container body 11 enter the carrier cavity 20 through the liquid guide pipe 3. When the first air exchange channel 120' is opened or the pump body assembly 4 supplies air, the liquid falls back to the container body 11 through the liquid guide pipe 3. The temperature control assembly 5 is arranged on the outer bottom wall of the container body 11 to heat or cool the liquid in the container body 11.

[0066] As shown in Figure 13 and Figure 15 , the cover body 121 of the container cover 12 is provided with an air suction port 1211 and an air exchange port 1212. The pump body assembly 4 is an air pump arranged in the container cover 12 and having an air suction function, and the air pump communicates with the air suction hole 1211. The first air exchange electromagnetic valve 81 opens or closes the air exchange port 1212, and the pump body assembly 4 and the first air exchange electromagnetic valve 81 are both accommodated in the container cover 12 and both communicate with the carrier cavity 20. The container body 11 has an upper edge 111 that is turned outward and rests on the shell 7, and the edge 111 of the carrier 2 is formed with an air exchange hole 112 that communicates with the inner cavity of the container body. Specifically, as shown in Figure 16 and Figure 17 , the upper edge 111 of the container body is sealingly connected to the top of the shell 7 by a sealing ring 9, the upper surface of the sealing ring 9 is formed with a groove 91 in the middle, and sealing lips 92 are formed on both sides of the groove 91. The air exchange pipeline 100' communicates with the air exchange hole 112 through the groove 91, and the second air exchange electromagnetic valve 82 communicates or blocks the air exchange pipeline.

[0067] As same as the first embodiment, the carrier 2 and the liquid guide tube 3 are detachably arranged in the container body 11, which makes the multi-functional grain germination device of the present embodiment have at least three cooking modes. When the carrier 2 and the liquid guide tube 3 are placed in the container body 11, the multi-functional grain germination device is in the first working mode for grain germination or preservation. When the carrier 2 and the liquid guide tube 3 are both removed from the container body 11 and the pump body assembly 4 stops working, the multi-functional grain germination device is in the second working mode for cooking rice. And when only the liquid guide tube 3 is removed and the pump body assembly 4 stops working, the multi-functional grain germination device is in the third working mode for food steaming. Specifically, the second working mode is the working mode of the existing braised rice electric rice cooker, and the third working mode is the working mode of the existing steamer; that is, the multi-functional grain germination device of the present embodiment has the functions of germination preservation, rice cooking and steaming.

[0068] When the multi-functional grain germination device of the present embodiment is in the first working mode, the liquid submerges the water flow passage 30 formed at the bottom of the liquid guide tube 3. The first air exchange electromagnetic valve 81 is closed to cover the air exchange port 1212 on the cover body 121, and the second air exchange electromagnetic valve 82 is opened to communicate the air exchange passage, so that air can enter the container body 11. The pump body assembly 4 pumps air out of the carrier cavity 20, and the pressure in the carrier cavity 20 decreases to form a negative pressure area, so that the liquid in the container body 11 enters the liquid guide tube 3 and gradually enters the carrier cavity 20 to soak the grains. After soaking for a set period of time, the pump body assembly 4 stops working and the first air exchange electromagnetic valve 81 is opened, so that external air enters the carrier cavity 20 through the air exchange port 1212, and the liquid falls along the liquid guide tube 3 under the action of gravity, and the grains germinate in a draining state. At the same time, external fresh air enters the carrier cavity 20 through the air exchange port 121, and the oxygen in the air gradually penetrates into the grains, providing oxygen for the germination of the grains in the draining state. After the draining germination satisfies the set period of time, the pump body assembly 4 is started again and the first air exchange electromagnetic valve 81 is closed to close the air exchange port 1212, and the pump body assembly 4 pumps air out of the carrier cavity 20, which not only discharges the turbid gas generated by the germination of the grains in the carrier cavity 20, but also causes the liquid to enter the carrier cavity 20 again to replenish the water for the grains. Then, the pump body assembly 4 stops working and the first air exchange electromagnetic valve 81 is opened, so that external air enters the carrier cavity 20 through the air exchange port 1212, and fresh air is introduced to increase the oxygen while the grains are germinating in a draining state.

[0069] In the present embodiment, the multi-functional grain germination device further comprises a temperature sensor 141 and a pressure sensor 142 arranged on the container cover 12 and extending into the carrier cavity 20. The temperature sensor 141 is used to detect the temperature of the grains or the liquid in the carrier cavity 20, and the pressure sensor 142 is used to monitor the pressure in the carrier cavity 20 when the pump body assembly 4 pumps air, so as to control the liquid level in the carrier cavity.

[0070] In the first working mode, when the pump body assembly 4 is pumping, the second air exchange electromagnetic valve 82 is in the open state, so that external air can enter the container body 11. When the pump body assembly 4 is not working, the second air exchange electromagnetic valve 82 can be closed or opened.

[0071] However, in the second working mode and the third working mode, the second air exchange electromagnetic valve 82 is always in the closed state, so that the container body 11 and the shell 7 are in the sealed state. Correspondingly, in the second working mode and the third working mode, the pump body assembly 4 is not working, but the first air exchange electromagnetic valve 81 is always open to the air exchange port 1212, so as to output the steam generated in the second working mode and the third working mode.

[0072] In summary, in the multifunctional grain germination device, the lower end of the liquid guide pipe and the inner bottom wall of the container body form a water flow channel below the liquid level, and the pressure regulating cavity is surrounded by the outer peripheral wall of the liquid guide pipe, the bottom wall of the bearing member, and the inner wall of the container body. The pump body assembly pumps or pumps air into the pressure regulating cavity, so that the liquid enters the bearing cavity to soak the grains through the liquid guide pipe; after the soaking time meets the requirements, the pump body assembly pumps air, and the liquid falls back to the container body under the action of gravity. This intermittent soaking method not only meets the moisture required for grain germination, but also avoids the problems of peculiar smell, sticky deterioration and the like caused by long-term soaking. In addition, since the air exchange channel is formed on the container cover, when the pump body assembly pumps air, the liquid enters the bearing cavity at the same time, and the turbid gas in the bearing cavity is discharged through the air exchange channel; and when the liquid falls back during pumping, external air is sucked through the air exchange channel to increase oxygen.

[0073] Further, since the bearing member and the liquid guide pipe are in a separable structure, after the two are removed or only the liquid guide pipe is removed, the multifunctional grain germination device can have a second working mode and a third working mode, thereby realizing the collection of multiple food processing functions. Further, the multifunctional grain germination device further comprises a temperature control assembly, which has two modes of heating and cooling, and quickly adjusts the temperature to accurately control the liquid temperature in different germination stages.

[0074] Although the present application has been disclosed by the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make some changes and modifications without departing from the spirit and scope of the present application, therefore the protection scope of the present application shall be subject to the scope claimed in the claims.
