Detailed ways

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, some technical features known in the art are not described in order to avoid confusion with the embodiments of the present invention.

For a thorough understanding of the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

The present invention provides a rice storage device, which can be used to store granular food materials such as rice and beans. However, it can be understood that the rice storage device according to the present invention can also store fruits or vegetables in the accommodating space. Therefore, the rice storage device can also be called a food storage device.

The rice storage device according to the present invention will be described in detail below with reference to the accompanying drawings.

housing unit

According to the present invention, the rice storage device includes a accommodating unit having an accommodating space. 1 and 2 show a accommodating bin 10 as an example of a accommodating unit. In addition, the rice storage device 1 further includes a base 20 . The accommodating bin 10 is configured as a separate structure from the base 20 and is detachably connected to the base 20 .

The accommodating bin 10 includes a bin body 11 and a bin cover 12 . The cartridge body 11 is generally constructed in the shape of a rounded rectangular parallelepiped, which has an inner space, and an opening communicated with the inner space is formed at the top. The bin cover 12 covers the top of the bin body 11 to close the opening. Thereby, a accommodating space 14 for storing food is formed between the bin cover 12 and the bin body 11 . Exemplarily, the accommodating space 14 can be set to have a larger volume, so that it can store 5-10 kg of food. The detachable setting allows the user to remove and clean the accommodating bin 10, so as to maintain a clean and hygienic environment inside, which is conducive to the long-term storage of ingredients.

The bin cover 12 can be fixedly connected to the bin body 11 , for example, by means of ultrasonic welding or the like. The cover 12 is provided with an additional cover 13 that can be opened and closed. The food can be placed in the accommodating space 14 by opening the additional cover 13 . In this way, the size of the additional cover 13 is smaller, and the opening and closing are more convenient. In addition, the opening corresponding to the additional cover 13 is small, which can reduce the possibility of dust or sundries falling into the accommodating space 14 through the opening when the additional cover 13 is opened. The additional cover 13 can be opened, for example, by pivoting about a pivot axis, by pushing and pulling along a chute, or by simply taking it off.

As an alternative embodiment, the bin cover 12 can also be configured to be able to open and close relative to the bin body 11 as a whole. For example, the bin cover 12 may be connected to the bin body 11 in a pivotable manner around a pivot axis or in a push-pull manner along a chute. At this time, the above-mentioned additional cover 13 can be selected to be retained or omitted as required.

The bottom of the bin body 11 is provided with a discharge port 15 that communicates with the accommodating space 14 . The ingredients stored in the accommodating space 14 can automatically flow out from the discharge port 15 under the action of gravity, which is convenient for the user to take. Therefore, the rice storage device 1 according to the present invention is particularly suitable for storing fluid granular food materials such as rice and beans. Preferably, the bottom of the cartridge body 11 may be configured as a bottom wall including an inclined inner side. The inner side can be formed by at least one inclined surface. And the discharge port 15 is provided at the lowest position of the inclined surface. It can be understood that, in this embodiment, the bottom of the cartridge body 11 is generally configured as an inverted pyramidal structure of a quadrangular pyramid. The outlet 15 is arranged at the top end of the inverted cone (ie, at the lowest position of the bin body 11 ). Thereby, the bottom of the bin body 11 has a slope, and it is possible to prevent the food material from remaining. As an alternative embodiment, the inner side surface of the bottom wall of the cartridge body 11 can also be configured as an arc-shaped inclined surface. Moreover, it can be understood that the inner surface of the bottom wall can be a combination of inclined surface and flat surface.

Preferably, one of the accommodating bin 10 and the base 20 can be provided with a snap position, and the other can be provided with a snap button. When the accommodating bin 10 is installed on the base 20 , the buckle is engaged with the card position, so that the two are locked together. As shown in FIG. 2 , in this embodiment, the accommodating bin 10 is provided with a latch 16 , and the base 20 is provided with a latch 22 . Of course, as an alternative embodiment, the accommodating bin 10 and the base 20 can also be locked by means of fasteners such as screws.

Decompression unit

The rice storage device 1 according to the present invention further includes a decompression unit 30 . The decompression unit 30 communicates with the accommodating space 14 for reducing the pressure in the accommodating space 14 to or below a predetermined pressure value. For example, the pressure in the accommodating space 14 can be made lower than the atmospheric pressure by pumping the accommodating space 14 . The state in which the pressure in the accommodating space 14 is lower than the atmospheric pressure may be referred to as a negative pressure state. In a negative pressure state, the air content—especially the oxygen content—in the accommodating space 14 is relatively low, which can significantly reduce the respiration of the stored ingredients, which is beneficial to the preservation of the ingredients during long-term storage.

As shown in FIG. 2 , the decompression unit 30 includes a vacuum pump 31 . The air inlet of the vacuum pump 31 is communicated with the accommodating space 14 so as to evacuate the accommodating space 14 . In the present embodiment, a vacuum pump 31 is provided in the base 20, which communicates with the accommodating space 14 through a suction pipe 32 such as a silicone hose. Such an arrangement can avoid arranging the vacuum pump 31 directly on the accommodating bin 10 , which is beneficial to reduce the weight of the accommodating bin 10 and make it lighter. Of course, in other embodiments, the vacuum pump 31 may also be disposed on the accommodating chamber 10 to shorten the gas flow path communicating between the two.

Further preferably, an air extraction channel 33 is provided in the accommodating space 14 . One end of the air extraction channel 33 is used to communicate with the air extraction pipe 32 , and the other end is provided at the top of the accommodating space 14 . As a result, the vacuum pump 31 draws air from the top of the accommodating space 14 , which can prevent food scraps or dust from entering the gas flow path of the decompression unit 30 to cause blockage.

reclaiming unit

In order to conveniently and smoothly take out the ingredients from the accommodating space 14 , the rice storage device 1 according to the present invention further includes a reclaiming unit 40 . As shown in FIG. 2 , FIG. 3 and FIG. 6 , the reclaiming unit 40 is disposed below the material outlet 15 of the accommodating space 14 , and has a material reclaiming cavity 43 and a material reclaiming port 44 . The reclaiming cavity 43 can move between a first position communicating with the material outlet 15 of the accommodating space 14 and a second position communicating with the material reclaiming port 44 . In the first position, the take-up cavity 43 is capable of receiving a predetermined amount of food material from the discharge port 15 . When the reclaiming chamber 43 moves from the first position to the second position, the received predetermined amount of food material can be taken out through the reclaiming port 44 .

Preferably, the reclaiming port 44 is arranged below the reclaiming cavity 43, and the food material in the reclaiming cavity 43 can be automatically dropped by gravity when the two are connected, which is convenient for the user to take.

Preferably, as shown in FIG. 2 , the rice storage device 1 further includes a material receiving box 60 disposed below the material taking port 44 to collect the taken out materials such as food materials. The receiving box 60 is provided in a removable manner. After the reclaiming unit 40 completes the reclaiming operation, the user can take the taken out ingredients from the receiving box 60 .

In this embodiment, the reclaiming unit 40 is provided in the base 20 . Such an arrangement is beneficial to reduce the weight of the accommodating bin 10 and make it lighter.

Specifically, as shown in FIG. 4 , the base 20 includes a top plate 21 extending in the lateral direction. The top plate 21 is recessed downward at a position corresponding to the discharge port 15 to form a recessed portion (not shown) with a circular cross section, so as to set the reclaiming unit 40 .

The reclaiming unit 40 also includes a turntable 42 for forming a movable reclaiming chamber 43 . Referring to FIG. 3 , the turntable 42 is substantially circular with a radially extending partition 421 . A plurality of partitions 421 are provided at intervals in the circumferential direction. A reclaiming cavity 43 is defined in the area between two adjacent partitions 421 . According to design requirements, the number of the partitions 421 can be set to two, three, five or more to respectively define two, three, five or more reclaiming chambers 43 . Wherein, each reclaiming cavity 43 may have an equal volume, or may be set to have volumes of different sizes. For example, taking rice as an example, the amount of rice that can be accommodated in each reclaiming cavity 43 can be set to be about 50-150 g, so as to facilitate the user to take quantitatively according to the number of diners. The capacity of the reclaiming chamber 43 can be set to 75g, 90g, 100g, 120g or any value within the above range.

The turntable 42 is provided in the recessed portion of the top plate 21 and can be rotated around the axis of the recessed portion by driving of a driving member such as a motor or the like. And, it can be understood that the material taking port 44 is provided on the bottom wall of the recessed portion. When the turntable 42 rotates, the reclaiming chamber 43 moves accordingly between a first position and a second position which are respectively communicated with the discharging port 15 and the discharging port 44 .

In addition, although not shown in the drawings, the reclaiming unit 40 may further include a cover plate which covers the recessed portion and seals the recessed portion. The cover plate is provided with a feed port for communicating with the discharge port 15 of the accommodating space 14 . Therefore, the internal space of the reclaiming unit 40 is kept sealed relative to the outside at other positions except that it can communicate with the accommodating space 14 through the feeding port and the outside world through the reclaiming port 44 .

In the above-mentioned embodiment, the portion of the top plate 21 of the base 20 for forming the concave portion can be regarded as an outer casing for accommodating the reclaiming unit 40 . As an alternative embodiment, the reclaiming unit 40 may not be provided in the base 20, and a separate component is used to form an outer casing with a cylindrical recess. For example, the turntable 42 can be arranged on the separate component, and then the outer casing can be hermetically connected to the bottom of the accommodating bin 10 in a way that the outlet 15 communicates with the cylindrical recess. In other words, the outer casing is fastened to the bottom of the accommodating compartment 10 . In this way, the above-mentioned cover plate can be omitted, and the accommodating bin 10 and the reclaiming unit 40 are provided with an integrated structure.

sealing unit

It can be seen from the above that the accommodating space 14 can be communicated with the outside through the discharge port 15 , the concave portion and the discharge port 44 . In order to ensure the sealing effect on the accommodating space 14 , as shown in FIG. 2 , the rice storage device 1 further includes a sealing unit 50 . Referring to FIGS. 4 to 7 , the sealing unit 50 includes a sealing plate 51 for sealing the discharge opening 44 . In addition, the sealing plate 51 can be in the sealing position of sealing the reclaiming port 44 (as shown in FIG. 4 and FIG. 6 ) and the opening position of opening the reclaiming port 44 (even if the reclaiming port 44 can communicate with the outside world) (as shown in FIG. 7 ). shown) to move between.

Therefore, when it is necessary to take food, the sealing plate 51 can be controlled to move to the open position as shown in FIG. 1 outside. When no food is needed to be taken, the sealing plate 51 can be controlled to move to the sealing position as shown in FIG. 4 and FIG. 6 , so that the accommodating space 14 cannot be communicated with the outside through the material taking port 44, so as to maintain a good sealing performance so that the to maintain vacuum.

According to the present invention, the sealing plate 51 is configured to move between the sealing position and the open position in a manner that is flipped about the flipping axis (similar to the manner in which a door is normally opened). Such an arrangement can allow the sealing plate 51 to have little or no frictional contact with other components during the movement process, thereby avoiding displacement or wear of the sealing surface caused by the frictional contact between the sealing plate 51 and other components, so that the sealing plate 51 is not in frictional contact with other components. 51 can maintain good sealing performance for a long time. In addition, the sealing plate 51 is fastened toward the material withdrawal port 44 when sealing the material withdrawal port 44 . In this way, on the premise that the overturning axis is determined, it can be ensured that the sealing plate 51 maintains the same relative position with the material taking port 44 every time it moves to the sealing position, so as to avoid the situation that the sealing is not tight.

Referring again to FIG. 5 , according to this embodiment, the sealing plate 51 includes two parts, the mounting plate 53 and the sealing gasket 52 . Wherein, the mounting plate 53 can be made of hard plastic material to have good supporting performance. The gasket 52 can be made of soft rubber material to have good sealing performance. The gasket 52 and the mounting plate 53 are individually formed and assembled as a whole. It will be appreciated, however, that the gasket 52 may also be integrally formed with the mounting plate 53 as a unitary member, such as by overmolding. Alternatively, the sealing plate 51 may also be a separate component completely made of a material with good sealing performance, such as soft sealing glue.

The sealing plate 51 is installed below the material taking port 44 through the rotating shaft 54 . The shaft 54 extends generally transversely and defines the pivot axis of the sealing plate 51 . In this way, on the one hand, the sealing plate 51 can avoid interference with the rotation of the turntable 42 of the reclaiming unit 40, and on the other hand, the self-gravity of the sealing plate 51 can be used to provide a part of the driving force for the opening of the sealing plate 51.

Continuing to refer to FIG. 5 , the sealing unit 50 further includes a sliding link 55 and a driving member 56 for driving the sealing plate 51 to flip and move between the sealing position and the opening position.

Specifically, the sealing plate 51 is provided with a first chute 531 on the side facing away from the material taking port 44 . The first chute 531 generally extends in a direction perpendicular to the turning axis (ie, the rotation axis 54 ), and has a lateral opening. The sliding link 55 is connected to the driving member 56 and is configured to be able to reciprocate in a lateral direction perpendicular to the turning axis under the driving of the driving member 56 . The slide link 55 includes a main body portion 551 and a slide shaft 552 . The sliding shaft 552 extends substantially parallel to the turning axis of the sealing plate 51 and extends into the first sliding groove 531 from the lateral opening. That is, the sliding shaft 552 is substantially perpendicular to the first sliding groove 531 , and can slide in the first sliding groove 531 with the reciprocating movement of the sliding link 55 so as to be close to or away from the turning axis.

Preferably, as shown in FIG. 4 and FIG. 5 , the first sliding grooves 531 may include two, which are arranged at intervals along the direction of the turning axis. The sliding link 55 is located between the two first sliding grooves 531 , and the sliding shafts 552 extend in opposite directions to respectively extend into the two different first sliding grooves 531 . Such an arrangement is beneficial to keep the first chute 531 and the sliding shaft 552 connected and avoid loosening.

As shown in FIG. 7, the sealing plate 51 is in the open position. At this time, if it is desired to move the sealing plate 51 to the sealing position as shown in FIG. 6 , the sliding link 55 can be driven to move laterally, so as to drive the sliding shaft 552 to move away from the turning axis (ie, the rotating shaft 54 ) in the first sliding groove 531 . move in the direction. The sliding shaft 552 exerts a thrust on the sealing plate 51 , and the action point of the thrust has a certain short distance from the turning axis, so a moment will be generated around the turning axis to turn the sealing plate 51 upward. The sealing plate 51 is moved to the sealing position towards the discharge opening 44 under the action of this moment.

Conversely, when it is desired to move the sealing plate 51 from the sealing position shown in FIG. 6 to the opening position shown in FIG. 7 , the sliding link 55 can be moved in the opposite direction to the above, so as to drive the sliding shaft 552 in the first The chute 531 moves in a direction close to the turning axis. With the movement of the sliding link 55 , the sealing plate 51 generates a downward moment around the turning axis under the dual action of its own gravity and the force of the sliding link 55 , so that the sealing plate 51 moves to the open position away from the material taking port 44 move.

In the present embodiment, the driving member 56 is configured as an electric motor, which is connected to the sliding link 55 through the rotating link 57 to drive it to reciprocate in the lateral direction. Specifically, the drive shaft 561 of the motor is arranged vertically. The rotating link 57 includes a transverse rod 571 and a vertical rod 572 . The transverse rod 572 is connected to the driving shaft 561 to rotate under the driving of the driving shaft 561 . The vertical rod 572 is arranged eccentrically with respect to the drive shaft 561 on the transverse rod 572 . Thus, the rotary link 57 is substantially constructed as a crank structure.

Further, the sliding link 55 further includes a second sliding groove 553 . The second sliding groove 553 extends in a lateral direction different from the moving direction of the sliding link 55 and has a vertical opening. The vertical rod 572 of the rotating link 57 extends into the second sliding slot 553 from the vertical opening, and can slide relative to the second sliding slot 553 . In this embodiment, the extending direction of the second sliding groove 553 is perpendicular to the moving direction of the sliding link 55 . However, it can be understood that the extending direction of the second sliding groove 553 can also form an included angle other than zero degree and vertical with the moving direction of the sliding link 55 . In addition, the main body portion 551 of the slide link 55 is also movably mounted by the mounting collar 24 . The mounting ring 24 is used to restrict the moving direction of the sliding link 55 .

According to the above structure, when the driving shaft 561 of the driving member 56 rotates, the distance between the vertical rod 572 of the rotating link 57 and the driving shaft 561 periodically changes in the moving direction of the sliding link 55 defined by the mounting hoop 24 . As a result, the vertical rod 572 slides along the second chute 553 and drives the overall position of the sliding link 55 to periodically change in its moving direction, thereby realizing the reciprocating movement of the sliding link 55 to drive the sealing plate 51 in the sealing move between position and open position.

In other words, the above-mentioned driving member 56 , the rotating link 57 and the sliding link 55 are connected to each other to form a crank-slider mechanism to convert the rotary motion of the driving member 56 into the linear reciprocating motion of the sliding link 55 .

However, since the rotational movement of the driving member 56 is periodic, it is difficult to judge which position the sealing plate 51 moves to by the movement of the driving member 56 itself. This is disadvantageous for the control of the sealing unit 50 . Therefore, although not shown in the drawings, it is understood that the sealing unit 50 may further include a detection member. The detection piece is configured to issue a position signal when the sealing plate 51 is moved to the sealing position and the opening position, respectively. At this time, the position of the sealing plate 51 can be judged by the in-position signal, so as to control the driving member 56 to work according to the judgement.

For example, the detection piece may include two microswitches, when the sealing plate 51 moves to the sealing position and the opening position, the corresponding microswitches are triggered respectively. The change of the state of the corresponding micro-switch means that the sealing plate 51 has been moved in place, and the driving member 56 can be controlled to stop working or continue working as required.

Of course, the detection element can also be constructed in other forms, such as a photoelectric switch including a light transmitter and a light receiver, and the like. When the sealing plate 51 is moved into position, it blocks the light signal between the light transmitter and the light receiver, and thus the change of state produced by the light receiver indicates that the sealing plate 51 has moved into position.

Further, the rice storage device 1 may further include a control unit 70 . The control unit 70 may include a control circuit board, which is electrically connected to the driving member 56 and the detection member respectively, and is configured to control the operation of the driving member 56 according to the in-position signal sent by the detection member, so as to realize automatic control.

In addition, it can be understood that in other embodiments not shown in the drawings, the opening and closing position of the sealing plate 51 can also be controlled by designing the stroke of the sliding link 55 . For example, the stroke of the sliding link 55 is designed so that when the sliding link 55 drives the sliding shaft 552 to move in a direction away from the turning axis to the stopping point of the sliding link 55 along the moving direction, the sealing plate 51 moves to the sealing position, And when the sliding link 55 drives the sliding shaft 552 to move along the direction close to the turning axis to the stop point of the sliding link 55 along the moving direction, the sealing plate 51 moves to the open position. In this way, precise control of the opening and closing of the sealing plate 51 can be realized through the physical structure.

In such an embodiment, the drive member 56 may be configured as an electromagnet. The sliding link 55 may be connected to the movable iron core of the electromagnet. The movable iron core of the electromagnet can reciprocate and have a predetermined stroke, thus meeting the above requirements. Since the moving manner of the movable iron core of the electromagnet is the same as that of the sliding link 55, the above-mentioned detecting member can be omitted, and the mounting hoop can be omitted.

In addition, the sealing unit of the rice storage device according to the present invention can also be configured such that the driving member directly acts on the rotating shaft to drive the sealing plate to move between the sealing position and the opening position. For example, the driving member may be an electric motor, and the driving shaft of the motor may be directly connected to the rotating shaft of the sealing member, and the rotational driving force directly acts on the rotating shaft to drive it to rotate. As a result, an intermediate structure such as a slide link for transmitting driving force can be omitted.

It can be understood that, in this embodiment, there is also a problem that the position of the sealing member cannot be determined. Therefore, the above-mentioned detection element, control unit, etc. can be applied in this embodiment to achieve precise control.

Unless otherwise defined, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of this invention.
