Hereinafter, a rice storage device according to various embodiments of the present invention will be described in detail with reference to fig. 1 to 7. In the first embodiment according to the present invention, as shown in fig. 1 to 5, the rice storage apparatus 100 includes a food material containing unit 110, a carrying case 120, a pressure reducing device 130, a pressure detecting device 150, and a sealing structure 140.
The food material accommodating unit 110 is configured as a box having a certain accommodating space, and the accommodating space can be used for accommodating food materials to be stored, such as granular food materials like rice. However, it is understood that in other embodiments, the food material accommodating unit 110 may store fruits or vegetables, etc., and accordingly, the rice storage device 100 may be referred to as a food material storage device. Exemplarily, the receiving space may be provided with a large volume such that it may store 5kg to 10kg of food material. The top of the food material accommodating unit 110 is provided with a cover 111, and the cover 111 can cover the food material accommodating unit 110 and can be hermetically connected with the food material accommodating unit 110. When the food material is placed in the food material accommodating unit 110, the covered cover 111 can protect the stored food material.
The carrier case 120 serves to support and fix the food material accommodating unit 110, and the food material accommodating unit 110 is disposed in the carrier case 120. The decompression device 130 and the pressure detection device 150 are also provided in the carrying case 120. The pressure reducing device 130 may include a vacuum pump, an air inlet of which is communicated with the accommodating space of the food material accommodating unit 110 through an air exhaust pipe made of, for example, a silica gel material, and an air outlet of which is communicated with the external environment of the accommodating space, for example, with the external air. When negative pressure state is formed in the accommodation space when needs make, usable vacuum pump carries out the operation of bleeding to accommodation space to reduce the pressure in the accommodation space, when vacuum pump stop work, form negative pressure state in the accommodation space. A state in which the pressure in the accommodating space is lower than the atmospheric pressure may be referred to as a negative pressure state.
The pressure detection device 150 is provided to protrude into the accommodation space, and is capable of detecting the pressure or vacuum degree in the accommodation space. For example, the pressure detection device 150 may partially or completely protrude into the receiving space. In the present embodiment, the pressure detection device 150 is a pressure sensor, and a head portion of the pressure sensor extends into the accommodation space. As shown in fig. 3, the height of the protrusion is 1 mm. Therefore, the rice in the food material containing unit 110 can be prevented from leaking out. It is of course also possible to detect the pressure or vacuum degree inside the food material containing unit 110 by placing it in a partial space communicating with the food material containing unit 110.
Further, the rice storage device 100 further comprises a sealing structure 140, the sealing structure 140 being capable of sealing the pressure detection device 150. The sealing structure 140 can circumferentially cover the pressure detection device 150, so that the pressure detection device 150 forms a seal with the food material containing unit 110 and the carrying case 120, thereby preventing external air from entering the food material containing unit 110, and ensuring the sealing effect of the food material containing unit 110.
The rice storage device 100 further comprises a control device (not shown), to which both the pressure detection means 150 and the pressure reduction means 130 are electrically connected. When the rice storage device needs to perform vacuum preservation on food materials, the decompression device 130 is started to perform air extraction operation on the accommodating space, meanwhile, the pressure detection device 150 can detect the pressure or the vacuum degree in the food material accommodating unit 110 in real time, and when the control device detects that the pressure in the food material accommodating unit 110 reaches a set pressure value through the pressure detection device 150, for example, the range of the set pressure value can be-30 KPA to-5 KPA, for example, -10KPA, the decompression device 130 can be controlled to stop working, so that the food materials in the accommodating space can be continuously preserved. In addition, the accommodating space may leak in the process of continuously keeping fresh, thereby affecting the effect of low-pressure fresh keeping. Therefore, when the preservation time exceeds 1 hour and the control device detects that the pressure value in the accommodating space is higher than-5 KPA (or the pressure value is 50% of the set pressure value) through the pressure detection device 150, the decompression device 130 can be activated to perform the air-extracting operation on the accommodating space to reduce the pressure thereof. In addition, when the time for keeping fresh is less than 1 hour, and the control device detects that the pressure value in the accommodating space is higher than-5 KPA (or the pressure value is 50% of the set pressure value) through the pressure detection device 150, the control device can utilize the alarm device to generate an alarm signal, so as to remind a user that the sealing of the accommodating space is in a problem and needs to be checked and maintained.
Further, the food material containing unit 110 is removably provided in the carrier case 120, so that the food material containing unit 110 is easily replaced and cleaned.
As shown in fig. 2, a support plate 121 is provided in the carrying case 120, the support plate 121 extends in a horizontal direction and divides an inner space of the carrying case 120 into a first cavity and a second cavity which are provided up and down, and the food material accommodating unit 110 is removably placed in the first cavity. In addition, the vacuum pump in the pressure reducing device 130 may be installed on the supporting plate 121, and a portion thereof extends into the second cavity, and another portion thereof extends into the first cavity, and is communicated to the accommodating space of the food material accommodating unit 110 through a structure such as an air exhaust pipe, so as to perform an air exhaust operation on the accommodating space. In other embodiments, not shown, the vacuum pump can be disposed entirely within the second cavity and communicate through the support plate 121 to the receiving space via a suction tube or the like.
The sealing structure 140 includes a first fitting portion 141, a second fitting portion 142, and a sealing member 143. Wherein the first matching portion 141 is disposed in the carrying case 120, and the pressure detecting device 150 is disposed in the first matching portion 141.

Exemplarily, the second fitting part 142 may be a cylindrical wall body provided at the bottom of the food material receiving unit 110 and extending downward in a vertical direction. When the food material containing unit 110 is placed on the carrying case 120, the first fitting portion 141 protrudes into the second fitting portion 142, and the pressure detecting device 150 can protrude into the containing space via the detection port, thereby being capable of detecting the pressure or the vacuum degree within the containing space. Further, the sealing member 143 is disposed between the first and second fitting portions 141 and 142, and can form a seal between the first and second fitting portions 141 and 142, thereby preventing external air from communicating with the receiving space of the food material receiving unit 110 via a gap between the first and second fitting portions 141 and 142.
In the first embodiment according to the present invention, as shown in fig. 2 and 3, the sealing member 143 may be an annular elastic sealing ring. The sealing element 143 is disposed on the outer wall of the first mating portion 141, and when the first mating portion 141 extends into the second mating portion 142, the sealing element 143 is elastically deformed, wherein the inner wall of the sealing element 143 along the radial direction thereof abuts against the outer wall of the first mating portion 141, and the outer wall of the sealing element 143 along the radial direction thereof abuts against the inner wall of the second mating portion 142. That is, after the seal 143 is elastically deformed, both end surfaces thereof opposing in the radial direction abut against the first fitting portion 141 and the second fitting portion 142, respectively, thereby forming a seal between the first fitting portion 141 and the second fitting portion 142. In addition, the second fitting portion 142 may be provided at an appropriate height according to the position of the sealing member 143.
Preferably, in order to prevent the sealing member 143 from being misaligned on the outer wall of the first fitting part 141 to affect the sealing effect, the outer wall of the first fitting part 141 is provided with a mounting groove extending along the circumferential direction thereof, and the sealing member 143 is seated in the mounting groove. Further, the outer wall of the first fitting portion 141 is provided with ribs 145 at intervals in the height direction of the first fitting portion 141, and mounting grooves can be formed between the ribs 145, thereby mounting the sealing member 143.
Further, the sealing structure 140 further includes an auxiliary packing 144, the auxiliary packing 144 being disposed between the pressure detecting device 150 and the distal end surface of the first fitting portion 141, the auxiliary packing 144 being capable of forming a seal between the first fitting portion 141 and the pressure detecting device 150 when the pressure detecting device 150 is mounted into the first fitting portion 141, thereby preventing the external air from communicating with the accommodating space of the food material accommodating unit 110 via the gap between the first fitting portion 141 and the pressure detecting device 150. Preferably, the auxiliary sealing member 144 may be an annular elastic sealing ring.
In this embodiment, a food material distribution unit 160 and a food material receiving unit 170 may be further disposed in the second cavity of the carrying case 120.
Specifically, as shown in fig. 2 and 4, the food material accommodating unit 110 has a funnel-shaped bottom and has a rice outlet 112, the rice outlet 112 is configured as a funnel-shaped bottom outlet, the food material dispensing unit 160 is disposed below the rice outlet 112 and is operable to receive rice from the rice outlet 112, and the food material receiving unit 170 is disposed below the food material dispensing unit 160 and is operable to receive rice from the food material dispensing unit 160. Preferably, the food receiving unit 170 may be a rice taking box provided in the rice storage device 100, which can be placed into the rice storage device 100 from the side along a predetermined track.
As shown in fig. 5, the food material dispensing unit 160 comprises a dispensing chamber 161, a dispensing motor 162 and a transmission mechanism 163. Wherein, the distribution motor 162 and the transmission mechanism 163 are disposed in the distribution chamber 161, and the distribution motor 162 can drive the transmission mechanism 163 to rotate. The distribution chamber 161 corresponds to the position of the rice outlet 112, and can receive the rice from the rice outlet 112. Further, the transmission mechanism 163 includes a plurality of dial plates provided coaxially with the dispensing motor 162, and when the dispensing motor 162 rotates, the dial plates can rotate within the dispensing chamber 161 about the rotation center of the dispensing motor 162. The plurality of toggle plates can partition the distribution chamber 161 into a plurality of food material containing chambers 164, and rice in the rice outlet 112 can fall into one of the food material containing chambers 164.
The bottom of the distribution chamber 161 is provided with a rice drop opening 165 corresponding to the food material receiving unit 170. After the rice in the food material containing unit 110 falls into the food material containing chamber 164 through the rice outlet 112, the distribution motor 162 rotates and drives the stirring plate to rotate in the distribution chamber 161, the position of the food material containing chamber 164 formed by the stirring plate rotates along with the stirring plate, and in the process that one food material containing chamber 164 sweeps over the rice outlet 165, the rice in the food material containing chamber 164 falls into the food material receiving unit 170 through the rice outlet 165. Then, the user can take out the food receiving unit 170 to obtain the required rice.
Specifically, during the rotation of the distribution motor 162, each food material containing chamber 164 receives a certain amount of rice when passing through the rice outlet 112 (it can be understood that the rice falls from the rice outlet 112 into one of the food material containing chambers 164 at a fast speed, and thus the received certain amount of rice is the amount of rice filling the food material containing chamber 164), when the food material containing chamber 164 with rice sweeps through the rice outlet 165, the rice falls into the food material receiving unit 170, and then the next food material containing chamber 164 continues to rotate to the rice outlet 112 to receive the rice again, and through such a circulation manner and by controlling the rotation angle of the distribution motor 162, the food material distribution unit 160 can quantitatively convey the rice from the food material containing unit 110 to the food material receiving unit 170. In this embodiment, the distribution chamber 161 is provided with 4 shifting plates, and the 4 shifting plates form a cross shape, that is, every time the distribution motor 162 rotates 90 degrees, one food material containing chamber 164 sweeps through the rice dropping opening 165. And each of the food material containing chambers 164 may be set to contain about 75g of 0.5 cup of rice therein. When the user needs to obtain a quantity of rice of 1 cup of rice (about 150g), the dispensing motor 162 may be rotated by 180 degrees so that the food receiving unit 170 receives rice in 2 food material containing chambers 164, and when the user needs to obtain a quantity of rice of 1.5 cups of rice (about 225g), the dispensing motor 162 may be rotated by 270 degrees so that the food receiving unit 170 receives rice in 3 food material containing chambers 164.
Further, when the poking plate stays right above the rice dropping opening 165, the rice dropping opening 165 can be completely covered, so that the rice dropping opening 165 is sealed. That is, the cross-sectional area of the toggle plate is greater than the cross-sectional area of the rice drop 165. Preferably, the rice drop opening 165 may be configured in a long bar shape so that the striking plate can completely cover the rice drop opening 165. In this embodiment, when the toggle plate rotates in the distribution chamber 161, it can push the rice in the food material containing chamber 164 to fall into the food material receiving unit 170 when the rice needs to be taken out, and can stay above the rice dropping opening 165 to seal the rice dropping opening 165 when the rice needs not to be taken out.
In the second embodiment according to the present invention, the rice storage device according to the second embodiment may have substantially the same configuration as the rice storage device 100 according to the first embodiment except for the configuration of the sealing structure, and therefore, only the distinctive technical features will be described in detail herein for the sake of brevity. Specifically, as shown in fig. 6, the sealing structure 240 includes a first fitting portion 241, a second fitting portion 242, and a sealing member 243. Wherein the first fitting portion 241 is provided in the carrier case, and the pressure detecting device 250 is provided in the first fitting portion 241, in particular, the first fitting portion 241 is configured as a wall body extending from the support plate 221 toward the ingredient accommodating unit 210.

The food material containing unit 210 has a detection opening at the bottom thereof, the second engaging portion 242 is provided at the detection opening of the food material containing unit 210 to correspond to the position of the first engaging portion 241, and the first engaging portion 241 is removably mounted in the first engaging portion 241. Exemplarily, the second fitting part 242 may be a cylindrical wall body provided at the bottom of the food material receiving unit 210 and extending downward in a vertical direction. When the food material containing unit 210 is placed on the carrying case, the first fitting portion 241 extends into the second fitting portion 242, and the pressure detecting device 250 can extend into the food material containing unit 210 through the detection port, thereby being capable of detecting the degree of vacuum in the containing space. Further, the sealing member 243 is disposed between the first and second fitting portions 241 and 242, and can form a seal between the first and second fitting portions 241 and 242, thereby preventing external air from communicating with the receiving space of the food material receiving unit 210 via a gap between the first and second fitting portions 241 and 242.
In the present embodiment, the sealing member 243 may be an annular elastic sealing ring. The sealing member 243 is disposed on the outer wall of the first fitting portion 241 and located at the bottom of the outer wall of the first fitting portion 241, and when the first fitting portion 241 extends into the second fitting portion 242, the sealing member 243 is elastically deformed, wherein the upper end surface of the sealing member 243 in the axial direction thereof abuts against the distal end surface of the second fitting portion 242, and the lower end surface of the sealing member 243 in the axial direction thereof abuts against the surface of the supporting plate 221. That is, after the seal 243 is elastically deformed, both end surfaces thereof opposing in the axial direction abut against the first fitting portion 241 and the second fitting portion 242, respectively, thereby forming a seal between the first fitting portion 241 and the second fitting portion 242.
The sealing member 243 in this embodiment may be considered to be interposed between the second engagement portion 242 and the support plate 221, and therefore the second engagement portion 242 needs to have a sufficient length so that it can abut against the sealing member 243, thereby achieving a good sealing effect.
Further, in the present embodiment, an auxiliary sealing member 244 is further disposed between the first matching portion 241 and the pressure detection device 250, and the structure and function of the auxiliary sealing member 244 are the same as those of the first embodiment, and are not described again here.

Specifically, as shown in fig. 7, the sealing structure includes a first fitting portion 341, a second fitting portion 342, and a sealing member 343. Wherein the first fitting portion 341 is provided in the carrier case and the pressure detecting device 350 is provided in the first fitting portion 341, in particular, the first fitting portion 341 is configured as a wall body extending from the support plate 321 toward the ingredient housing unit 310. Illustratively, the first fitting portion 341 may be a cylindrical wall body provided on the support plate 321 and extending upward in the vertical direction. The food material containing unit 310 has a detection port at the bottom thereof, the second engaging portion 342 is provided at the detection port of the food material containing unit 310 to correspond to the first engaging portion 341, and the first engaging portion 341 is removably mounted in the first engaging portion 341. Exemplarily, the second fitting part 342 may be a cylindrical wall body provided at the bottom of the ingredient containing unit 310 and extending downward in a vertical direction. When the food material containing unit 310 is placed on the carrying case, the first fitting portion 341 extends into the second fitting portion 342, and the pressure detecting device 350 can extend into the food material containing unit 310 via the detection port, thereby being capable of detecting the degree of vacuum in the containing space. Further, a sealing member 343 is provided between the first and second fitting portions 341 and 342, and can form a seal between the first and second fitting portions 341 and 342, thereby preventing external air from communicating with the receiving space of the food material receiving unit 310 via a gap between the first and second fitting portions 341 and 342.
The seal 343 in this embodiment can be regarded as a combination of the seal and the auxiliary seal in the above two embodiments. Specifically, in the present embodiment, the seal 343 may be an annular elastic seal ring. The sealing member 343 is provided between the pressure detecting means 350 and the distal end surface of the first fitting portion 341, and when the pressure detecting means 350 is mounted into the first fitting portion 341, the sealing member 343 is elastically deformed by being pressed to form a seal between the first fitting portion 341 and the pressure detecting means 350, thereby preventing the outside air from communicating with the accommodating space of the food material accommodating unit 310 via the gap between the first fitting portion 341 and the pressure detecting means 350. Further, the maximum diameter of the outer end face of the seal member 343 in the radial direction thereof is larger than the inner wall diameter of the second fitting portion 342, so that in the mounted state in which the first fitting portion 341 is mounted in the second fitting portion 342, the outer end face of the seal member 343 can abut against the inner wall of the second fitting portion 342 to form an abutting seal. Illustratively, the outer end surface of the sealing member 343 may be configured as a slope, a circular arc, or the like, so that the second fitting portion 342 can be elastically deformed better, thereby increasing the sealing effect between the sealing member 343 and the inner wall of the second fitting portion 342. Since the seal member 343 is provided at the end of the first fitting portion 341, in the present embodiment, the height of the second fitting portion 342 in the axial direction thereof may be relatively small as long as it is possible to ensure that the inner wall of the second fitting portion 342 can sufficiently contact the seal member 343.
The present invention has been illustrated by the above embodiments, but it should be understood that the above embodiments are for illustrative and descriptive purposes only and are not intended to limit the invention to the scope of the described embodiments. Furthermore, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that many variations and modifications may be made in accordance with the teachings of the present invention, which variations and modifications are within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
