In daily life, food materials such as rice are often used to buy a large amount at a time and stored by using a rice storage device such as a plastic rice bucket, a metal rice bucket, a ceramic rice bucket, and the like. Most of the rice storage devices simply isolate the space for storing rice from the external space, and cannot control various parameters such as temperature and humidity of the rice storage space. For example, rice breathes during long-term storage and generates more heat. And heat is not easy to dissipate in a closed storage space, and the food materials are easy to decay in a high-temperature environment. In addition, when the rice is taken from the rice storage device, the storage space is communicated with the external environment, and the temperature, the humidity and the like of the storage space are easily influenced by the external environment. The problems of moisture, mildew, aging, insect growth and the like are easy to occur after long-time storage, so that the fresh-keeping is difficult to achieve for a long time, and bad experience is brought to users.

Detailed Description

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 specific details. In other instances, well-known features have not been described in detail so as not to obscure the embodiments of the invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that 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 for storing granular food materials such as rice, beans and the like. However, it is understood that the rice storage device according to the present invention may also store fruits or vegetables, etc. in the accommodating space. Therefore, the rice storage device may also be referred to as food storage device.

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

Accommodating unit

According to the present invention, a rice storage device includes a receiving unit having a receiving space. Fig. 1 and 2 show a housing bin 10 as one example of a housing unit. Furthermore, the rice storage device 1 comprises a base 20. The receiving container 10 is constructed in a separate structure from the base 20 and is detachably coupled to the base 20.

The accommodating chamber 10 includes a chamber body 11 and a chamber cover 12. The cartridge body 11 is generally configured in the shape of a rounded rectangular parallelepiped having a space inside and forming an opening at the top communicating with the inside space. A bin cover 12 covers the top of the bin body 11 to close the opening. Thus, a storage space 14 for storing food materials is formed between the bin cover 12 and the bin body 11. Exemplarily, the receiving space 14 may be provided with a larger volume such that it may store 5-10kg of food material. The detachable arrangement mode allows a user to detach and clean the accommodating bin 10, so that the inside of the accommodating bin is kept in a clean and sanitary environment, and long-time storage of food materials is facilitated.

The bin cover 12 may be fixedly connected to the bin body 11, for example by means of ultrasonic welding or the like. The lid 12 is provided with an additional lid 13 which can be opened and closed. The food material can be placed in the receiving space 14 by opening the additional cover 13. Thus, the additional cover 13 is smaller in size, and is more convenient to open and close. And the opening corresponding to the additional cover 13 is small, so that the possibility that dust, impurities and the like fall into the accommodating space 14 through the opening when the additional cover 13 is opened can be reduced. The additional cover 13 can be opened, for example, by pivoting about a pivot axis, by pushing and pulling along a chute, or by direct removal.

Alternatively, the lid 12 may be provided so as to be entirely openable and closable with respect to the body 11. For example, the lid 12 can be connected to the body 11 in a pivotable manner about a pivot axis or in a manner that is pushable and retractable along a chute. The additional cover 13 may be optionally retained or omitted at this time as desired.

The bottom of the bin body 11 is provided with a discharge hole 15 communicated with the accommodating space 14. The food material stored in the accommodating space 14 can automatically flow out of the discharge hole 15 under the action of gravity, so that the food material is convenient for a user to take. Therefore, the rice storage device 1 according to the present invention is particularly suitable for storing granular food materials having fluidity such as rice, beans, and the like. Preferably, the bottom of the cartridge body 11 can be configured as a bottom wall comprising inclined inner side surfaces. The inner side surface may be formed of at least one inclined surface. And the discharge hole 15 is provided at the lowest position of the inclined surface. It will be appreciated that in this embodiment, the bottom of the cartridge body 11 is generally configured in the reverse tapered configuration of a rectangular pyramid. The discharge port 15 is provided at the top end of the reverse taper (i.e., at the lowest position of the cartridge body 11). Therefore, the bottom of the bin body 11 has a slope, so that food material residue can be avoided. Alternatively, the inner side surface of the bottom wall of the cartridge body 11 may be configured as an arc-shaped inclined surface. Further, it is understood that the inner side surface of the bottom wall may be a combination of an inclined surface and a flat surface.

Preferably, one of the bin 10 and the base 20 can be provided with a detent, and the other with a catch. When the accommodating bin 10 is mounted on the base 20, the buckle is engaged with the detent, so that the two are locked. As shown in fig. 2, in the present embodiment, the storage chamber 10 is provided with a detent 16, and the base 20 is provided with a catch 22. Of course, as an alternative embodiment, the cartridge 10 and the base 20 may be locked by means of fastening means such as screws.

Pressure reducing unit

The rice storage 1 according to the invention further comprises a decompression unit 30. The decompression unit 30 communicates with the accommodating space 14 for reducing the pressure within the accommodating space 14 to or below a predetermined pressure value. For example, the pressure in the accommodating space 14 may be made lower than the atmospheric pressure by evacuating the accommodating space 14. A state in which the pressure inside the accommodating space 14 is lower than the atmospheric pressure may be referred to as a negative pressure state. Under the negative pressure state, the air content, especially the oxygen content, in the accommodating space 14 is low, so that the respiration of the stored food material can be obviously weakened, and the food material can be kept fresh for a long time.

As shown in fig. 2, the decompression unit 30 includes a vacuum pump 31. An air inlet of the vacuum pump 31 communicates with the accommodating space 14 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 an evacuation tube 32 such as a silicone hose. Such an arrangement can avoid the vacuum pump 31 being directly disposed on the accommodating chamber 10, which is beneficial to reducing the weight of the accommodating chamber 10 and making it more portable. Of course, in another embodiment, the vacuum pump 31 may be disposed on the housing chamber 10 to shorten the gas flow path communicating therebetween.

Further preferably, an air suction channel 33 is provided in the accommodation space 14. The suction passage 33 has one end for communicating with the suction pipe 32 and the other end disposed at the top of the accommodating space 14. Accordingly, the vacuum pump 31 draws air from the top of the accommodating space 14, which can prevent the food scraps or dust from entering the gas flow path of the decompression unit 30 to cause blockage.

Material taking unit

In order to facilitate the smooth removal of the food material from the accommodating space 14, the rice storage device 1 according to the present invention further includes a taking out unit 40. As shown in fig. 2, 3 and 6, the material taking unit 40 is disposed below the discharge port 15 of the accommodating space 14, and has a material taking cavity 43 and a material taking port 44. Wherein the material taking chamber 43 is movable between a first position communicating with the discharge port 15 of the accommodating space 14 and a second position communicating with the material taking port 44. In the first position, the material taking chamber 43 is able to receive a predetermined amount of food material from the outlet 15. When the take-out chamber 43 is moved from the first position to the second position, the received predetermined amount of food material may be taken out through the take-out opening 44.

Preferably, get material mouth 44 and set up in the below of getting material chamber 43, can utilize gravity to make the edible material in getting material chamber 43 fall automatically when the two communicate, convenience of customers takes.

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

In the present embodiment, the take-out unit 40 is provided in the base 20. Such an arrangement is advantageous in that the weight of the cartridge 10 is reduced, making it more lightweight.

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 recess (not shown) having a circular cross section to provide the take-out unit 40.

The take-off unit 40 also includes a turntable 42 for forming a movable take-off chamber 43. Referring to fig. 3, carousel 42 is generally circular with radially extending partitions 421. The partitions 421 are provided in plurality at intervals in the circumferential direction. The area between two adjacent partitions 421 defines a take-out chamber 43. The number of the partitions 421 may be set to two, three, five or more to define two, three, five or more take-out chambers 43, respectively, according to design requirements. Each of the material taking cavities 43 may have an equal volume, or may be configured to have different volumes. For example, taking rice as an example, the amount of rice that can be accommodated in each taking chamber 43 can be set to about 50-150g, so that a user can take the rice quantitatively according to the number of people having a meal. The volume of the take-up chamber 43 may be set to 75g, 90g, 100g, 120g, or any value within the above range.

The turntable 42 is provided in a recessed portion of the top plate 21 and is rotatable about an axis of the recessed portion by a drive member such as a motor. Also, it will be appreciated that the material pick-up port 44 is provided in the bottom wall of the recess. As the turntable 42 rotates, the take-off chamber 43 moves between first and second positions in communication with the outlet 15 and the take-off port 44, respectively.

In addition, although not shown, the take-out unit 40 may further include a cover plate that covers and seals the recess. The cover plate is provided with a feed inlet for communicating with a discharge outlet 15 of the accommodating space 14. The interior of the removal unit 40 is thus sealed off from the environment at any other point than via the inlet opening to the receiving space 14 and via the removal opening 44.

In the above embodiment, the portion of the top plate 21 of the base 20 for forming the depression may be regarded as an outer case that houses the taking unit 40. Alternatively, the material extracting unit 40 may not be provided in the base 20, and a separate member may be used to form an outer case having a cylindrical recess. For example, the rotary disk 42 may be provided on the separate member, and the outer housing may be hermetically connected to the bottom of the accommodating chamber 10 in such a manner that the discharge port 15 communicates with the cylindrical recess. In other words, the outer case is fastened to the bottom of the receiving chamber 10. This makes it possible to omit the provision of the above-described cover plate, and to provide the accommodating chamber 10 with an integrated structure with the taking unit 40.

Sealing unit

As described above, the accommodating space 14 can communicate with the outside through the discharge port 15, the recess, and the material taking port 44. In order to secure the sealing effect against the accommodating space 14, as shown in fig. 2, the rice storage device 1 further includes a sealing unit 50. Referring to fig. 4 to 7, the sealing unit 50 includes a sealing plate 51 for sealing the material taking port 44. Further, the sealing plate 51 is movable between a sealing position (shown in fig. 4 and 6) for sealing the material discharge port 44 and an opening position (shown in fig. 7) for opening the material discharge port 44 (i.e., for allowing the material discharge port 44 to communicate with the outside).

Thereby, when it is necessary to take out the food material, the sealing plate 51 may be controlled to move to the open position as shown in fig. 7 so that the food material taken out of the accommodating space 14 by the taking-out unit 40 may be taken out to the outside of the rice storage device 1 through the taking-out port 44. When the food material is not needed to be taken out, the sealing plate 51 can be controlled to move to the sealing position shown in fig. 4 and 6, so that the accommodating space 14 cannot be communicated with the outside through the material taking port 44, and a good sealing performance is maintained so as to maintain the vacuum degree.

According to the present invention, the sealing plate 51 is configured to move between the sealing position and the opening position in a manner that flips about a flipping axis (similar to the manner in which a door is opened on a daily basis). Such an arrangement may allow the sealing plate 51 to have little or no frictional contact with other components during movement, so that displacement or abrasion of the sealing surface due to the frictional contact between the sealing plate 51 and other components may be avoided, and the sealing plate 51 may maintain good sealing performance for a long time. The sealing plate 51 is engaged with the material inlet 44 when sealing the material inlet 44. Therefore, on the premise that the overturning axis is determined, the sealing plate 51 can be ensured to keep the same relative position with the material taking port 44 when moving to the sealing position every time, and the condition of untight sealing is avoided.

Referring again to fig. 5, according to the present embodiment, the sealing plate 51 includes two parts, a mounting plate 53 and a gasket 52. The mounting plate 53 may be made of a hard plastic material to have a good supporting performance. The sealing pad 52 may be made of a soft rubber material to have a good sealing performance. The gasket 52 and the mounting plate 53 are each separately formed and assembled as a single body. However, it will be appreciated that the seal 52 may also be formed integrally with the mounting plate 53 as a one-piece member, such as by overmolding. Alternatively, the sealing plate 51 may be a separate member made entirely of a material having good sealing performance, such as a sealant.

The sealing plate 51 is installed below the material taking port 44 by a rotating shaft 54. The shaft 54 extends generally transversely and defines a flip axis of the seal plate 51. So set up, on the one hand can avoid the closing plate 51 to produce the interference to the rotation of the carousel 42 of extracting unit 40, and on the other hand, can also utilize the gravity of closing plate 51 self to provide some drive power for opening of closing plate 51.

With continued reference to fig. 5, the sealing unit 50 further includes a sliding link 55 and a driver 56 for driving the sealing plate 51 to flip-over move between the sealing position and the open position.

Specifically, the sealing plate 51 is provided with a first chute 531 on a side facing away from the material taking port 44. The first chute 531 extends substantially in a direction perpendicular to the flip axis (i.e., the rotation axis 54) and has a transverse opening. The slide link 55 is connected to the driver 56, and is configured to be reciprocally movable in a lateral direction perpendicular to the tumble axis by the driver 56. The slide link 55 includes a body 551 and a slide shaft 552. Wherein the sliding shaft 552 extends substantially parallel to the turning axis of the sealing plate 51 and projects from the lateral opening into the first chute 531. That is, the sliding shaft 552 is substantially perpendicular to the first slide groove 531, and is capable of sliding within the first slide groove 531 to approach or separate from the tumble axis with the reciprocating movement of the slide link 55.

Preferably, as shown in fig. 4 and 5, the first chute 531 may include two, which are spaced apart in the direction of the flipping axis. The slide link 55 is located between the two first slide grooves 531, and the slide shafts 552 extend in opposite directions to protrude into the two different first slide grooves 531, respectively. Such an arrangement is advantageous in that the first chute 531 and the sliding shaft 552 are kept connected to avoid looseness.

As shown in fig. 7, the sealing plate 51 is in the open position. At this time, if it is desired that the seal plate 51 is moved to the sealing position as shown in fig. 6, the slide link 55 may be driven to move in the lateral direction to move the slide shaft 552 in the first slide groove 531 toward a direction away from the turning axis (i.e., the rotation shaft 54). The sliding shaft 552 applies a thrust force to the seal plate 51, the point of action of which is a short distance from the turning axis, and thus generates a moment about the turning axis that turns the seal plate 51 upward. The sealing plate 51 moves to the sealing position toward the material discharge port 44 by the moment.

Conversely, when it is desired to move the seal plate 51 from the sealing position shown in fig. 6 to the opening position shown in fig. 7, the slide link 55 may be moved in the opposite direction to that described above to move the slide shaft 552 in the first chute 531 toward the direction close to the flip axis. As the sliding link 55 moves, the sealing plate 51 generates a downward moment about the tilting axis under the dual action of its own weight and the force of the sliding link 55, thereby moving the sealing plate 51 toward the open position away from the material taking port 44.

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

Further, the slide link 55 further includes a second slide slot 553. The second slide slot 553 extends in a lateral direction different from the moving direction of the slide link 55 and has a vertical opening. The vertical rod 572 of the rotating link 57 protrudes from the vertical opening into the second slide slot 553, and is slidable with respect to the second slide slot 553. In the present embodiment, the extending direction of the second chute 553 is perpendicular to the moving direction of the slide link 55. However, it is understood that the extending direction of the second slide slot 553 may also form an angle other than zero degrees and perpendicular with the moving direction of the slide link 55. Further, the body 551 of the slide link 55 is also movably mounted by the mounting band 24. The mounting collar 24 serves to limit the direction of movement of the sliding link 55.

According to the above structure, when the driving shaft 561 of the driving member 56 rotates, the vertical rod 572 of the rotating link 57 periodically changes in distance from the driving shaft 561 in the moving direction of the sliding link 55 defined by the mounting hoop 24. Thereby, the vertical rod 572 slides along the second sliding groove 553, and drives the position of the entire slide link 55 to periodically change in the moving direction thereof, thereby achieving the reciprocating movement of the slide link 55 to drive the seal plate 51 to move between the sealing position and the opening position.

In other words, the above-described 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 rotational motion of the driving member 56 into the linear reciprocating motion of the sliding link 55.

However, since the rotational movement of the driver 56 is periodic, it is difficult to judge to which position the sealing plate 51 is moved by the movement of the driver 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 sensing member. The detector is configured to send out a go-to-go signal when the sealing plate 51 moves to the sealing position and the opening position, respectively. The position of the sealing plate 51 can be determined by the position signal, and the operation of the driving member 56 can be controlled according to the determination.

For example, the detection member may comprise two microswitches which trigger the corresponding microswitches when the sealing plate 51 is moved to the sealing position and the open position, respectively. The change in state of the corresponding microswitch indicates that the sealing plate 51 has moved into position and the actuator 56 can be controlled to stop or continue to operate as desired.

Of course, the detection member may be configured in other forms, such as an opto-electronic switch including an optical transmitter and an optical receiver, and the like. When the sealing plate 51 is moved into position, it blocks the optical signal between the optical transmitter and the optical receiver, and the change in state produced by the optical receiver indicates that the sealing plate 51 has been moved into position.

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

In addition, it is understood that in other embodiments not shown in the drawings, the opening and closing of the sealing plate 51 can be controlled by designing the stroke of the sliding link 55. For example, the stroke of the slide link 55 is designed such that the seal plate 51 is moved to the sealing position when the slide link 55 carries the slide shaft 552 to move in the direction away from the turning axis to the stop point of the slide link 55 in the moving direction, and the seal plate 51 is moved to the opening position when the slide link 55 carries the slide shaft 552 to move in the direction close to the turning axis to the stop point of the slide link 55 in the moving direction. In this way, the opening and closing of the sealing plate 51 can be accurately controlled by the physical structure.

In such an embodiment, the drive member 56 may be configured as an electromagnet. The slide link 55 may be connected to the movable core of the electromagnet. The movable core of the electromagnet can be reciprocated and has a predetermined stroke, thereby satisfying the above requirements. Since the movable core of the electromagnet moves in the same manner as the slide link 55, the above-described detection member can be omitted, and the mounting collar can be omitted.

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

It will be appreciated that in this embodiment as well, there is a problem in that the position of the seal cannot be determined. Thus, the above-described detection member, control unit, and the like can be applied to this embodiment to achieve precise control.
