Description

Technical Field

[0001] This application relates to the technical field of small household appliances, and particularly to a rice storage box and a rice cooker. Background Art

[0002] A rice cooker is a cooking appliance that uses electrical energy to convert into heat energy to cook food, and it can perform various cooking operations such as steaming, boiling, stewing, simmering, and braising. Most rice cookers on the market need to add rice manually before cooking. With the further development of smart home appliances, rice cookers that can automatically add rice have been developed. Such rice cookers include components such as a cooker body and a rice storage box. In order to facilitate automatic rice addition, a certain amount of rice is usually stored in the rice storage box. However, rice is prone to mildew and insect infestation after being stored for a long time. According to common sense, four conditions are required for rice to mildew and be infested with insects: bacteria and insect eggs, appropriate temperature, humidity, and sufficient oxygen content. Therefore, in order to enable the rice storage box to store rice for a long time, breakthroughs can be made from the following three directions: 1. Directly kill bacteria and insect eggs; 2. Control the temperature; 3. Control the humidity and oxygen content.

[0003] The rice storage boxes on the market usually do not have a sterilization function, resulting in the inability to store rice for a long time. There are usually two sterilization methods adopted by users: 1. Open slots on the lid of the rice storage box and place desiccants in the slots; 2. Open slots on the lid of the rice storage box and place spices with pungent odors such as garlic and star anise in the slots to sterilize. However, although desiccants can control humidity, the control effect is unstable, and as time goes by, the desiccants will lose their water absorption effect after being saturated and need to be replaced regularly. The sterilizing spices are also unstable, and the sterilization effect is very poor, with only a minimal sterilizing effect. Thus, it can be seen that the existing rice storage boxes cannot achieve long-term rice storage. Summary of the Utility Model

[0004] Based on this, it is necessary to provide a rice storage box and a rice cooker that can achieve long-term rice storage.

[0005] This application provides a rice storage box, including a box body. A rice storage cavity is provided inside the box body. An air outlet, an air inlet, and a rice outlet communicating with the rice storage cavity are provided on the box body. A vacuum pumping device is provided at the air outlet, and the vacuum pumping device is used to pump vacuum for the rice storage cavity. A first valve is provided at the air inlet, and the first valve is used to open and close the air inlet; a second valve is provided at the rice outlet, and the second valve is used to open and close the rice outlet.

[0006] In one embodiment, the first valve includes a first valve body and a first valve core rotatably disposed within the first valve body. The first valve body has a first inlet and a first outlet. The first inlet communicates with the outside, and the first outlet communicates with the air inlet. The first valve core has a first channel. When the first channel communicates the first inlet and the first outlet, the first valve opens the air inlet; when both ends of the first channel are blocked by the inner wall of the first valve body, the first valve closes the air inlet. The second valve includes a second valve body and a second valve core rotatably disposed within the second valve body. The second valve body has a second inlet and a second outlet. The second inlet communicates with the rice outlet. The second valve core has a second channel. When the second channel communicates the second inlet and the second outlet, the second valve opens the rice outlet; when both ends of the second channel are blocked by the inner wall of the second valve body, the second valve closes the rice outlet.

[0007] In one embodiment, the first valve core and the second valve core are fixedly connected by a connecting rod. The first valve core or the second valve core is connected to a driving member, and the driving member is used to drive the first valve core and the second valve core to rotate.

[0008] In one embodiment, a limiting protrusion is provided on the first valve core or the second valve core, and a limiting groove extending along the rotation direction of the first valve core and the second valve core is provided on the first valve body or the second valve body. The limiting protrusion extends into the limiting groove and can move between the two side walls at both ends of the limiting groove to limit the rotation range of the first valve core and the second valve core.

[0009] In one embodiment, a connecting sleeve is sleeved outside the connecting rod, and the connecting sleeve connects the first valve body and the second valve body.

[0010] In one embodiment, a controller is further included. The controller is electrically connected to the vacuum pumping device and the driving member to control the respective operations of the vacuum pumping device and the driving member.

[0011] In one embodiment, a pressure sensor electrically connected to the controller is further included. The pressure sensor is at least partially disposed within the rice storage cavity to detect the air pressure within the rice storage cavity.

[0012] In one embodiment, the air inlet and the rice outlet are disposed on the same side of the box body. The air inlet is disposed above the rice outlet. A partition is provided on one side of the box body near the air inlet and the rice outlet. The partition and the side wall of the box body enclose an air circulation cavity. The air circulation cavity has a circulation inlet and a first circulation outlet. The circulation inlet communicates with the first outlet, and the first circulation outlet communicates with the second inlet.

[0013] In one of the embodiments, a filter screen is provided at the air inlet.

[0014] The present application also provides a rice cooker, including: a rice cooker main body, a blower, and the rice storage box as described above. The blower is connected to the second valve and the rice cooker main body through a pipeline to suck the materials in the rice storage cavity into the rice cooker main body.

[0015] Compared with the prior art, the present application can evacuate the rice storage cavity by setting a vacuum pumping device, so that the rice storage cavity can be conveniently set as a vacuum environment. In a vacuum environment, the survival rate of bacteria and insect eggs is low, so that long-term rice storage can be realized. Since the inside of the rice storage cavity is a vacuum environment after evacuation and the air pressure is lower than the atmospheric pressure, if only the rice outlet is opened at this time, the rice in the box is not easy to be output from the rice outlet. By setting an air inlet in the present application, when the rice storage box needs to output rice, the first valve opens the air inlet, so that air enters the rice storage cavity, so that the air pressure in the rice storage cavity rises and returns to the normal pressure state, so that the rice can be smoothly output from the rice outlet.

Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0026] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it can be directly on the other component or there can also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the description of the present application are only for the purpose of illustration and do not represent the only implementation manner.

[0027] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0028] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first feature is in direct contact with the second feature, or the first feature is indirectly in contact with the second feature through an intermediate medium. Moreover, the first feature being "above", "over" or "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" or "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0029] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0030] Please refer to Figures 1 to 4 , this application provides a rice storage box 100, which includes a box body 10. A rice storage cavity 11 is provided inside the box body 10. An air outlet 115, an air inlet 116 and a rice outlet 112 communicating with the rice storage cavity 11 are provided on the box body 10. A vacuum pumping device 20 is provided at the air outlet 115. The vacuum pumping device 20 is used to pump vacuum for the rice storage cavity 11. A first valve 50 is provided at the air inlet 116. The first valve 50 is used to open and close the air inlet 116. A second valve 60 is provided at the rice outlet 112. The second valve 60 is used to open and close the rice outlet 112. In this way, by setting the vacuum pumping device 20, the rice storage cavity 11 can be pumped to a vacuum, so that the rice storage cavity 11 can be conveniently set as a vacuum environment. In a vacuum environment, the survival rate of bacteria and insect eggs is low, so that long-term rice storage can be realized. For example, in a -60KPa vacuum environment, the humidity is 27%-30%, the oxygen content is 5%, and bacteria and insect eggs cannot survive. It can be understood that before pumping vacuum, the air inlet 116 is closed by the first valve 50, and the rice outlet 112 is closed by the second valve 60 to ensure that no air enters the air inlet 116 and the rice outlet 112, so that the vacuum pumping device 20 can be started to pump vacuum for the rice storage cavity 11. Since the inside of the rice storage cavity 11 is a vacuum environment after pumping vacuum and the air pressure is lower than the atmospheric pressure, if only the rice outlet 112 is opened at this time, the rice in the box body 10 is not easily output from the rice outlet 112. By providing the air inlet 116 in this application, when the rice storage box 100 needs to output rice, the first valve 50 opens the air inlet 116 to allow air to enter the rice storage cavity 11, so that the air pressure in the rice storage cavity 11 rises and returns to the normal pressure state, so that the rice can be smoothly output from the rice outlet 112.

[0031] It is understandable that a filter screen is provided at the air extraction port of the vacuum device 20 to prevent the rice in the rice storage cavity 11 from being sucked away.

[0032] Please refer to Figure 1 and Figure 2 As shown in FIGS. and, a rice adding port 111 communicating with the rice storage cavity 11 is provided at the top of the box body 10, and rice is added into the rice storage cavity 11 through the rice adding port 111. In addition, the rice storage box 100 may further include a box cover 40 sealingly connected to the rice adding port 111. By providing the box cover 40, foreign objects can be prevented from falling into the rice storage cavity 11, which is beneficial to keeping the inside of the rice storage cavity 11 clean. The box cover 40 is sealingly connected to the box body 10 to ensure that there is no air leakage at the connection between the box cover 40 and the box body 10 during vacuum pumping, so as to ensure that the rice storage box 100 can store rice for a long time.

[0033] Please refer to Figure 3 and Figure 4 As shown in FIGS. and, the first valve 50 includes a first valve body 51 and a first valve core 52 rotatably disposed within the first valve body 51. The first valve body 51 has a first inlet 511 and a first outlet 512. The first inlet 511 communicates with the outside, and the first outlet 512 communicates with the air inlet 116. The first valve core 52 has a first channel 521. When the first channel 521 communicates the first inlet 511 and the first outlet 512, the first valve 50 opens the air inlet 116; when both ends of the first channel 521 are blocked by the inner wall of the first valve body 51, the first valve 50 closes the air inlet 116. In this way, the opening and closing control of the air inlet 116 can be achieved by controlling the rotation of the first valve core 52. The structure of the first valve 50 is simple, and the control method is also simple.

[0034] The second valve 60 includes a second valve body 61 and a second valve core 62 rotatably disposed within the second valve body 61. The second valve body 61 has a second inlet 611 and a second outlet 612. The second inlet 611 communicates with the rice outlet 112. The second valve core 62 has a second channel 621. When the second channel 621 communicates the second inlet 611 and the second outlet 612, the second valve 60 opens the rice outlet 112; when both ends of the second channel 621 are blocked by the inner wall of the second valve body 61, the second valve 60 closes the rice outlet 112. In this way, the opening and closing control of the rice outlet 112 can be achieved by controlling the rotation of the second valve core 62. The structure of the second valve 60 is simple, and the control method is also simple.

[0035] Furthermore, the first valve core 52 and the second valve core 62 are fixedly connected by a connecting rod 72. In this way, the first valve core 52 and the second valve core 62 can rotate synchronously. The first valve core 52 or the second valve core 62 is connected to a driving member 80, and the driving member 80 is used to drive the first valve core 52 and the second valve core 62 to rotate. By setting the driving member 80 to control the rotation of the first valve core 52 and the second valve core 62, the air inlet 116 and the rice outlet 112 can be opened or closed simultaneously, and the operation is very convenient.

[0036] In this embodiment, the driving member 80 is a motor, but it is not limited thereto. In other embodiments, the driving member 80 can also be a rotary cylinder or other devices capable of controlling the rotation of the first valve element 52 and the second valve element 62.

[0037] Please refer to Figure 1 and Figure 2 , further, a limiting protrusion 523 is provided on the first valve element 52 or the second valve element 62, and a limiting groove 513 extending along the rotation direction of the first valve element 52 and the second valve element 62 is provided on the first valve body 51 or the second valve body 61. The limiting protrusion 523 extends into the limiting groove 513 and can move between the two side walls at both ends of the limiting groove 513 to limit the rotation range of the first valve element 52 and the second valve element 62. In this way, by providing the limiting protrusion 523 and the limiting groove 513, the rotation range of the first valve element 52 and the second valve element 62 can be limited, so as to ensure that when the air inlet 116 and the rice outlet 112 are opened or closed, the first valve element 52 and the second valve element 62 can rotate in place. The two side walls at both ends of the limiting groove 513 are respectively the open position and the closed position. When the motor drives the first valve element 52 and the second valve element 62 to rotate counterclockwise and the limiting protrusion 523 reaches the open position, the motor stalls, so that the first valve element 52 and the second valve element 62 stop rotating. At this time, the air inlet 116 and the rice outlet 112 are opened. When the motor drives the first valve element 52 and the second valve element 62 to rotate clockwise and the limiting protrusion 523 reaches the closed position, the motor stalls, so that the first valve element 52 and the second valve element 62 stop rotating. At this time, the air inlet 116 and the rice outlet 112 are closed.

[0038] In this embodiment, please refer to Figure 2 and Figure 4 , a connecting rod 522 is provided on the first valve element 52. The connecting member passes through the first valve body 51 and is connected to the driving member 80 (i.e., the motor). The limiting protrusion 523 is provided on the connecting rod 522 of the first valve element 52, and the limiting groove 513 is provided on the first valve body 51. Of course, the limiting protrusion 523 and the limiting groove 513 can also be provided at other positions, as long as the two cooperate to limit the rotation range of the first valve element 52 and the second valve element 62.

[0039] Further, a connecting sleeve 71 is sleeved outside the connecting rod 72. The connecting sleeve 71 connects the first valve body 51 and the second valve body 61. In this way, the connecting sleeve 71 can protect the connecting rod 72, prevent foreign objects from damaging the connecting rod 72 or affecting the rotation of the connecting rod 72, and can keep the appearance beautiful.

[0040] In this embodiment, the first valve core 52 and the second valve core 62 are connected as a whole by a connecting rod 72, and the first valve body 51 and the second valve body 61 are connected as a whole by a connecting sleeve 71. Therefore, the first valve 50 and the second valve 60 can be regarded as one valve. The valve body of this valve includes a first valve body 51 and a second valve body 61, and the valve core of this valve includes a first valve core 52 and a second valve core 62. Further, as Figure 2 shown, the valve body can be formed by splicing a valve seat 561 and a valve cover 562. In this way, it is convenient to install the valve core in the valve body. In this embodiment, the valve body is split in half into a valve seat 561 and a valve cover 562, but it is not limited to this. In other embodiments, the valve body can also be in other forms, as long as the valve core can be installed in the valve body.

[0041] Further, please refer to Figure 1 and Figure 2 . The rice storage box 100 further includes a controller 90. The controller 90 is electrically connected to the vacuum pumping device 20 and the driving member 80 to control the respective operations of the vacuum pumping device 20 and the driving member 80. In this way, by controlling the vacuum pumping device 20 and the driving member 80 through the controller 90, intelligent control can be achieved. In this embodiment, the controller 90 is provided on the rice storage box 100, but it is not limited to this. The controller 90 can also be provided on the rice cooker main body 200.

[0042] Further, the rice storage box 100 further includes a pressure sensor 91 electrically connected to the controller 90. The pressure sensor 91 is at least partially disposed in the rice storage cavity 11 to detect the air pressure in the rice storage cavity 11. In this way, by providing the pressure sensor 91, the air pressure in the rice storage cavity 11 can be detected in real time. The pressure sensor 91 is electrically connected to the controller 90, and the pressure sensor 91 can timely feedback the air pressure in the rice storage cavity 11 to the controller 90. Thus, when evacuating, when the air pressure reaches a preset value, the controller 90 can control the vacuum pumping device 20 to stop working.

[0043] In this embodiment, the air inlet 116 and the rice outlet 112 are provided on the same side of the box body 10. The air inlet 116 is provided above the rice outlet 112. The structure is very compact and it is convenient to arrange the first valve 50 and the second valve 60 connected as a whole.

[0044] A filter screen 1161 is provided at the air inlet 116. In this way, it can be avoided that the rice in the rice storage cavity 11 leaks out from the air inlet 116 when the air inlet 116 is opened.

[0045] Please refer to Figure 7, the rice storage box 100 provided by the present application can be applied to an electric rice cooker. The way it outputs rice is to use the fan 300 to suck out the rice outlet 112, so as to suck the rice in the rice storage cavity 11 and enter the main body 200 of the electric rice cooker. It is worth mentioning that the reason why the rice can be sucked by the fan 300 is that when the fan 300 rotates at a high speed, it drives the air to flow. The air flow generates a negative pressure to suck the rice along the air flow direction. If there is only rice in the pipeline 400 and no air, the rice cannot be sucked.

[0046] As Figure 4 shown, a partition 30 is provided on one side of the box body 10 near the air inlet 116 and the rice outlet 112. The partition 30 and the side wall of the box body 10 enclose an air circulation cavity 12. The air circulation cavity 12 has a circulation inlet 121 and a first circulation outlet 122. The circulation inlet 121 is communicated with the first outlet 512, and the first circulation outlet 122 is communicated with the second inlet 611. In this way, by setting the air circulation cavity 12, when it is necessary to output rice from the rice outlet 112, under the suction of the fan 300, the outside air can enter the air circulation cavity 12 through the circulation inlet 121 and enter the second inlet 611 of the second valve body 61 through the first circulation outlet 122, so that there is enough flowing air in the second inlet 611. At the same time, the rice in the rice storage cavity 11 falls to the rice outlet 112 due to gravity and enters the second inlet 611 under the suction of the fan 300. In the second inlet 611, the air and the rice are fully mixed, and there is a large amount of flowing air between the rice grains, so that the rice can smoothly pass through the second valve 60 and be sucked away, avoiding the situation that the rice is blocked in the second inlet 611.

[0047] In this embodiment, the first circulation outlet 122 is located above the rice outlet 112. In this way, it is ensured that there is always high-speed flowing air above the second inlet 611, so that the rice can be sucked up and sucked away. And after the fan 300 stops, the rice will not fill the second inlet 611 and cause blockage.

[0048] Further, a second circulation outlet 123 is provided on the partition plate 30. The second circulation outlet 123 communicates with the air circulation chamber 12 and the rice storage chamber 11, and the second circulation outlet 123 is arranged close to the first circulation outlet 122 and the rice outlet 112. In this way, a part of the air in the air circulation chamber 12 enters the rice storage chamber 11 through the second circulation outlet 123 and mixes with the rice, thereby increasing the amount of air between the rice grains, making it easier for the rice in the rice storage chamber 11 to be sucked into the second inlet 611 and sucked away. In this embodiment, by providing the second circulation outlet 123, the air in the air circulation chamber 12 has two flow paths. A part of the air enters the second inlet 611 from the first circulation outlet 122, and another part of the air enters the rice storage chamber 11 from the second circulation outlet 123 and enters the second inlet 611 from the rice outlet 112, further increasing the mixing effect of the rice and the air and making the rice suction smoother.

[0049] Further, an aggregate area 113 is provided on the bottom wall of the rice storage chamber 11 adjacent to the rice outlet 112, and a drainage slope 114 is provided in the rice storage chamber 11. The drainage slope 114 connects the side wall of the rice storage chamber 11 and the aggregate area 113. In this way, the rice in the rice storage chamber 11 can flow along the drainage slope 114 to the aggregate area 113 due to the action of gravity and flow from the aggregate area 113 to the rice outlet 112. It can be seen that the provision of the aggregate area 113 and the drainage slope 114 makes it easier for the rice to flow to the rice outlet 112, thus avoiding the occurrence of flow dead zones.

[0050] Please refer to Figure 7 , the present application also provides an electric rice cooker, including: an electric rice cooker main body 200, a blower 300, and the rice storage box 100 as described above. The blower 300 is connected to the second valve 60 and the electric rice cooker main body 200 through a pipeline 400 to suck the materials in the rice storage chamber 11 into the electric rice cooker main body 200. When rice storage is required, the air inlet 116 and the rice outlet 112 are closed, and the vacuum pumping device 20 is started to pump the rice storage chamber 11 into a vacuum so that the rice storage chamber 11 is in a vacuum environment where bacteria and eggs are difficult to survive. When cooking rice is required, the air inlet 116 and the rice outlet 112 are opened. As Figure 5 shown, the air flow path in the rice storage box 100 at this time ( Figure 5 the arrows in indicate the air flow path) includes: 1. External air flows in from the first valve 50 and is divided into two streams. One stream enters the rice storage chamber 11 from the air inlet 116, and the other stream enters the air circulation chamber 12 from the circulation inlet 121; 2. The air in the electric rice cooker main body 200 (equivalent to external air) flows into the rice storage chamber 11 from the rice outlet 112. When the blower 300 is turned on, as Figure 6 shown, the air flow path in the rice storage box 100 ( Figure 6As shown by the arrows in the figure, the air flow path (including): 1. External air flows in from the first valve 50 and is divided into two streams. One stream enters the rice storage chamber 11 from the air inlet 116, and the other stream enters the air circulation chamber 12 from the circulation inlet 121; 2. The air in the rice storage chamber 11 flows out to the atmosphere together with the rice through the second valve 60 at the rice outlet 112. At the same time, the air in the rice storage chamber 11 flows out to the atmosphere through the second valve 60 at the first circulation outlet 122. It can be seen that this rice cooker can achieve automatic rice storage and automatic rice discharging, with a high degree of intelligence.

[0051] As Figure 7 shown, a fan filter 301 can be provided at the front end of the fan 300. The fan filter 301 can intercept rice, so that the rice can fall into the rice cooker main body 200 without entering the fan 300. The rice cooker main body 200 includes a cooker body. The fan 300 can suck the rice into the cooker body. In addition, the rice cooker main body 200 can also be provided with a rice washing chamber. The fan 300 first sucks the rice into the rice washing chamber to wash the rice and then enters the cooker body.
