It is to be understood that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments 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.

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. Of course, as an alternative embodiment, the cartridge 10 and the base 20 may be locked by means of fastening means such as screws. Alternatively, the rice storage device may be constructed as an integral structure different from the present embodiment.

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 exhaust tube (not shown) such as a silicone hose or the like. 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.

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. 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.

As shown in fig. 2, the taking unit 40 is disposed below the discharge port 15 of the accommodating space 14. The take-out unit 40 has a take-out chamber 43 and a take-out 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.

In one embodiment, the reclaiming unit 40 may include a turntable. The turntable has a plurality of radially extending partitions. The area between two adjacent partitions defines a take-out chamber 43. In addition, the material extracting unit 40 further includes a driving member 41. The driving member 41 is used for driving the turntable to rotate so as to realize the movement of the material taking cavity 43 between the first position and the second position.

Further, 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 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 addition, although not shown, the take-off unit 40 may also include a seal. This sealing member can be sealed get the sealed position of material mouth 44 and make and get the material mouth 44 and move between the open position of external intercommunication to the switching of material mouth 44 is got in the control, and convenience of customers carries out and gets the material operation. And also to maintain the containment space 14 sealed from the environment when material removal is not required to facilitate a negative pressure environment.

As described above, the material receiving box 60 can be taken out from the base 20. Therefore, the material receiving box 60 may be forgotten to be mounted at the material receiving position (or mounting position). At this time, if the material taking unit 40 is controlled to perform the material taking operation, the material taken out of the receiving space may be scattered in the base 20, causing waste of food and difficulty in cleaning. In addition, there is a case where the material receiving box 60 is taken out during the material taking operation performed by the material taking unit 40, which also causes the spilling and waste of the material.

In order to solve the above problems, according to the present invention, as shown in fig. 2, the rice storage device 1 further includes a sensing unit 80. The detection unit 80 is used for sending out an in-position signal when the material receiving box 60 is installed at the material receiving position. Thus, the rice storage device 1 can judge whether the current material receiving box 60 is correctly installed according to whether the in-place signal exists.

In one embodiment, the detection unit 80 may include a micro switch 81. When the material receiving box 60 is mounted in place, it presses the touch button of the microswitch 81, so that the microswitch 81 is changed from the disconnected state to the connected state. Therefore, the connection state of the microswitch 81 is the above-mentioned on signal.

As an alternative embodiment, the detection unit 80 may further include a photoelectric switch. The photoelectric switch includes a light emitting end and a light receiving end. When the material receiving box 60 is mounted in place, it blocks the light path from the light emitting end to the light receiving end, so that the photoelectric switch changes from the on state to the off state. Therefore, the connection state of the photoelectric switch is the above-mentioned in-place signal. Of course, the detecting unit 80 and the corresponding in-place signal can have various other embodiments, which are not listed here.

With continued reference to fig. 1 and 2, the rice storage device 1 further comprises a control unit 50, which may comprise a control circuit board (not shown). The control circuit board is electrically connected with all functional components of the rice storage device 1 so as to control the operation of the rice storage device. For example, the control circuit board may be electrically connected to the driving member 41 of the material extracting unit 40 to control the material extracting unit 40 to perform the material extracting operation. Further, the control unit 50 may be electrically connected to the detection unit 80, and may receive the in-place signal sent by the detection unit 80, and be configured to control the operating state of the driving member 41 of the material taking unit 40 according to the in-place signal.

Specifically, when the rice storage device 1 is powered on, the control unit 50 first judges whether there is currently an in-place signal. If the control unit 50 can receive the in-position signal sent by the detection unit 80, it can be determined that the material receiving box 60 is currently located at the installation position. The drive member 41 of the take-out unit 40 is now allowed to operate. Once the user issues an instruction to perform a material-taking operation, the control unit 50 may send a signal to the driving member 41 to control the operation thereof, so that the driving member 41 operates to drive the material-taking chamber 43 to move between the first position and the second position, thereby completing the material-taking operation.

If the control unit 50 does not receive the in-position signal sent by the detection unit 80, it is determined that the material receiving box 60 is not correctly installed in place currently. The control unit 50 inhibits the operation of the driving member 41 of the material extracting unit 40 at this time. Even if the user gives an instruction to perform the material taking operation, the driving member 41 does not operate, so that the material taken out by the material taking unit 40 can be prevented from being spilled.

Although not shown in the drawings, it is understood that the rice storage device 1 may further comprise a reminder unit. The presentation unit is electrically connected to the control unit 50. When the control unit 50 does not receive the in-position signal sent by the detection unit 80, it may control the prompting unit to send a prompt message to prompt the user that the material receiving box 60 is not properly installed in place currently. For example, the prompting unit may include members such as a display screen, an indicator lamp, a buzzer, a speaker, and the like to emit prompting information. Accordingly, the presentation information may be visual information such as character information and light information, or may be auditory information such as voice information and audio information. Preferably, the cue unit may comprise a combination of two or more of the above mentioned components.

Further, the rice storage device 1 may further comprise a locking unit 70 as shown in fig. 2. The locking unit 70 can lock the material receiving box 60 installed in the material receiving position at the position, and the user cannot take it out. Therefore, the phenomenon that the material receiving box 60 is taken out by mistake in the material taking process to cause material spilling is avoided.

In the present embodiment, the material receiving box 60 is provided in the base 20 in a drawn manner. The locking unit 70 may include a movable bar 72 and a lock actuator 71. The movable rod 72 is telescopically arranged under the driving of the locking driving piece 71, can extend into a moving path for taking out the material receiving box 60 to block the material receiving box 60 from moving so as to realize the locking of the material receiving box 60, and can also retract from the moving path so as to allow the material receiving box 60 to be taken out.

As shown in fig. 2, the lock actuating member 71 is configured as an electromagnet, and the movable rod 72 is configured as or connected to an iron core of the electromagnet to be telescopically movable in a straight line by the electromagnet. However, as an alternative, the lock drive 71 can also be configured as a motor and/or the movable lever 72 can also have other movements than a movement in a linear direction, for example a lever configured to rotate about an axis or the like.

Further, the locking unit 70 is electrically connected with the control unit 50. The control unit 50 is configured to control the locking unit 70 based on the operating state of the driving member 41 of the taking unit 40. Specifically, when the drive member 41 is in the active state, it indicates that a material extracting operation is being performed at that time. In this case, the material receiving box 60 is not allowed to be removed. Therefore, the control unit 50 controls the locking unit 70 to lock the material receiving box 60 at the material receiving position. The user cannot take out the material receiving box 60, thereby avoiding misoperation. When the driving member 41 is in the inactive state, it indicates that no material-taking operation is being performed. At this time, the control unit 50 controls the locking unit 70 to unlock the magazine 60. The user may remove the material receiving box 60 to collect the material therein or to clean it, etc.

The control method according to the invention is described below with reference to fig. 3 and 4 in connection with a preferred embodiment of the rice storage means.

When the rice storage device is powered on, the control unit detects the material box. That is, the control unit judges whether the detection unit sends the in-place signal. Specifically, in the present embodiment, whether or not the microswitch is closed is determined. If the microswitch is closed at this time, the control unit receives a signal that the microswitch is closed, namely a go-to-bit signal, from the S1 port of the microswitch. Illustrating the timing of the cartridge in place. Thereby allowing the take-out unit to operate. When the microswitch is not closed, the control unit receives a signal from the S1 port of the microswitch that it is open. The signal is not a in-place signal, that is, the control unit does not receive the in-place signal sent by the microswitch. The receiving box is not installed in place at the moment, so that the material taking unit is forbidden to work.

Further, the control unit may also send a signal to control the operation of the alarm lamp of the alarm unit to the control port K1. The alarm lamp is lightened to send prompt information to a user so as to remind that the material receiving box is not installed in place.

When the micro switch is closed, namely the material receiving box is installed in place, the control device allows the material taking unit to work. At this time, if the user desires to execute the material taking operation, the user can send out an instruction for starting the material taking operation through a button and the like. In the material taking operation, the control unit monitors the working state of a driving piece of the material taking unit. When the driving piece is in a working state, the control unit controls the locking unit to lock the material receiving box at the material receiving position. As shown in fig. 3, the control unit may send a control signal to a control port D1 for driving a motor (lock driving member) of the lever (movable rod) to rotate forward, so that the lever moves into the moving path of the material receiving box and is locked.

And when the driving part is in a non-working state, the control unit controls the locking unit to be in an unlocked state so as to allow the material receiving box to be taken out. As shown in fig. 3, the control unit may send a control signal to a control port F1 where a motor (lock drive) driving a lever (movable lever) is reversed, causing the lever to be removed from the movement path of the magazine, thereby releasing the lock. It will be appreciated that the control unit may choose to control the motor to produce no action to hold the dial in this position if the dial itself is now in the unlocked state.
