When each stirring roller is adapted to stir the rice in the storage tank, the liquid introduced by the adding unit is sprayed on the rice evenly through the holes, thereby preventing the rice from getting dried caused by the evaporation of the water owing to the stirring action of each stirring roller and greatly improving the poor texture of the stirred rice.

Description

[Technical Field]

[0001] This invention relates to the design of an automatic output device, and more particularly to an automatic rice output machine. [Previous Technology]

[0002] Referring to Figures 1 and 2, a conventional rice feeder 1 has a base 11, and a storage tank 12, a stirring unit 13, an output unit 14, and a control drive unit 15 respectively disposed on the base 11; wherein, the base 11 is divided into a rice serving area 111 and a storage area 112, and a cover 113 is fitted onto the base 11 to seal the storage area 112, the rice serving area 111 is arranged in a recessed open form, and the storage area 112 is located inside the base 11 and communicates with the rice serving area 111; in addition, the storage tank Storage tank 12 is used to hold rice and is located in storage area 112. Each storage tank 12 has an opening 121 and an output port 122 corresponding to the rice holding area 111. A stirring unit 13 is mounted on the base 11. The stirring unit 13 has an output roller 131 pivotally mounted at the output port 122 and at least two stirring rollers 132 pivotally mounted within the storage tank 12. Each stirring roller 132 has blades 132a arranged around its surface, and any two corresponding stirring rollers 132 rotate in different directions. The blades 132a... The rice is stirred and pushed to the output port 122, where it is discharged by the discharge roller 131. The output unit 14 has a switch 141 located between the output port 122 and the rice serving area 111, and a weight sensor 142 connected to the switch 141. The switch 141 switches between different opening and closing modes to receive and output rice according to the rice serving area 111. The weight sensor 142 senses the weight of the rice received by the switch 141 and generates a signal output. Finally, the control drive unit 15 has a control module. 151, a transmission assembly 152, and a power source 153 electrically connected to the control module 151, the transmission assembly 152, the output roller 131, and the output unit 14 respectively. The control module 151 is located on the surface of the base 11 to receive control commands from external operations and is connected to the power source 153. The transmission assembly 152 is located outside the storage tank 12 and is connected to the turning roller 132. The power source 153 receives control commands to appropriately drive the transmission assembly 152, the output roller 131, and the switch 141 to generate a driving connection.

[0003] Before use, the cooked rice is placed into the storage tank 12, and the storage tank 12 is sealed within the storage area 112 by the lid 113. When using the rice, the user places a container 2 in the rice-holding area 111 and selects the desired output amount from the control module 151 located on the surface of the base 11. If a smaller output amount of rice is selected, the power source 153 receives the control command output from the control module 151 and drives the mixing rollers 132 in the transmission... Driven by the assembly 151, the rice in the storage tank 12 is loosely turned and pushed towards the output port 122. Guided by the rotation of the guide roller 131, the rice enters the switch 141 through the output port 122. The weight sensor 142 senses the weight of the rice in the switch 141 and outputs a sensing signal. Driven by the power source 153, the switch 141 then opens to the container 2, allowing the rice to be placed into it. This completes the rice output for consumption.

[0004] However, after use, it was found that the conventional rice feeder 1, in order to prevent the rice from clumping together due to its static state before outputting the rice, thus affecting the taste, uses the stirring rollers 132 to rotate in the storage tank 12 and uses the agitation of the blades 132a to loosen it. However, given the limited moisture content of the rice, the continuous stirring action of the stirring rollers 132 causes excessive loss of moisture in the rice, resulting in the rice becoming dry. This affects the taste of the rice after it is output and needs to be improved. [Summary of the Invention]

[0005] Therefore, the purpose of this invention is to provide an automatic rice output machine that utilizes the addition of liquid during the process of loosening the rice to maintain the moisture of the rice, thereby increasing the taste of the rice.

[0006] Therefore, the automatic rice output machine of the present invention includes a base, a storage tank, a stirring unit, an adding unit, and a control output unit electrically connected to the stirring unit and the adding unit respectively; wherein, the stirring unit, which is mounted on the base, has an output roller pivotally mounted at the output port of the storage tank, and at least two stirring rollers pivotally mounted in the storage tank, and each stirring roller has a hollow flow channel formed inside, and each stirring roller has blades arranged around its surface and a plurality of holes communicating with the hollow flow channel. Any two corresponding stirring rollers rotate in different directions, and the blades stir the rice and push it to the output port of the storage tank for output by the output roller. In addition, the adding unit has a container located on one side of the storage tank. The system includes a conveyor connected to the mixing rollers and the container, with liquid added to the container. The liquid is then introduced into the hollow channel by the conveyor. The mixing unit features a hollow channel within the mixing rollers and a plurality of holes on the surface of the mixing rollers. Combined with an addition unit connected to the hollow channel, the liquid from the container is introduced into the hollow channel during the mixing rollers' process of loosening the rice. This allows the liquid to be evenly sprayed onto the rice through the holes, preventing excessive moisture loss during mixing and improving the texture of the rice after mixing, effectively maintaining the moisture content of the rice.

Implementation Method

[0007] The foregoing description and other technical contents, features and effects of the present invention will become clear in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0008] Referring to Figures 3 and 4, in a first comparative embodiment of the present invention, the automatic rice output machine 3 includes a base 31, a storage tank 32, a stirring unit 33, an adding unit 34, and a control output unit 35 electrically connected to the stirring unit 33 and the adding unit 34 respectively; wherein, the base 31 has a seat body 311 that divides a rice serving area 311a and a storage area 311b, and a cover body 312 that covers the seat body 311 and seals the storage area 311b, the rice serving area 311a can accommodate a container 4, and the storage area 311b is located on the seat body 311. It is connected to the rice serving area 311a; in addition, the storage tank 32 is used to hold a large amount of rice and place it in the storage area 311b. The storage tank 32 has a holding space 320 for holding rice. At the same time, the storage tank 32 has an opening 321 that communicates with the holding space 320 and an output port 322 that corresponds to the rice serving area 311a. The opening 321 corresponds to the cover 312. That is, when the cover 312 is closed on the base 31, the opening 321 is blocked and cannot communicate with the outside. At the same time, the storage tank 32 is set in the storage area 311b in an inclined form.

[0009] Continuing from the foregoing, the mixing unit 33 has an outlet roller 331 pivotally mounted at the outlet 322, and at least two mixing rollers 332 pivotally mounted at the storage tank 32 and located within the accommodating space 320. Each mixing roller 332 has a hollow flow channel 332a formed inside, and each mixing roller 332 has blades 332b arranged around its surface and a plurality of holes 332c communicating with the hollow flow channel 332a. Any two corresponding mixing rollers 332 can rotate in different / same directions, so that the blades 332b mix the rice when rotating. At the same time, the rice placed in the accommodating space 320 is pushed to the outlet 322 by the spiral mixing generated by the blades 332b and discharged by the outlet roller 331. 1. In this embodiment, the number of mixing rollers 332 can be increased or decreased as needed, which will not be elaborated below. Furthermore, the adding unit 34 is provided on the base 311. The adding unit 34 has a container 341 located on one side of the storage tank 32, and a conveyor 342 connected to the mixing rollers 332 and the container 341 respectively. The container 341 is filled with liquid, which can be drinking water or drinking water mixed with a small amount of edible oil, etc. In this embodiment, drinking water is used as an example. The amount of drinking water in the container 341 is guided to the hollow flow channel 332a by the conveyor 342 and can be selected and set in advance according to the addition needs in a timed and quantitative manner, or according to the number of rotations of the mixing rollers 332.

[0010] Continuing from the above, the control output unit 35 includes a control module 350, a switch 351 located between the output port 322 and the serving area 311a and connected to the control module 350, and a weight sensor 352 located on one side of the switch 351 and connected to the control module 350. The aforementioned control module 350 is electrically connected to the stirring unit 33 and the adding unit 34, respectively. The control module 350 is a touch panel with multiple selection touches, or it may have a display screen and multiple buttons. The configuration of the control module 350 in the figure is only shown in a simplified diagram to illustrate the configuration when the control module 350 is pressed. When pressed, the stirring unit 33, the adding unit 34, the switch 351, and the weight sensor 352 are activated. At the same time, the switch 351 corresponds to the rice serving area 311a to switch different opening and closing modes to receive and output rice. The weight sensor 352 senses the weight of the rice received by the switch 351 and generates a signal output. The weight sensor 352 can be preset with several weight sensing settings, such as using three different weights as distinctions, such as the first weight for a small amount of rice, the second weight for a normal amount of rice, and the third weight for an extra amount of rice. The signal output will only be generated if the sensed weight does not match the setting.

[0011] Referring to Figures 3 and 4, firstly, the storage slot 32 is positioned at the storage area 311b, and a large amount of cooked rice is placed into the receiving space 320 through the opening 321. Then, the cover 312 is placed on the base 311, so that the opening 321 cannot communicate with the outside due to the cover 312 being closed. Next, a power source A connected to the control module 350 is activated to output power, so that the control module 350 is displayed on the base 31 in a selectable operation mode. After forming an electrical connection with the mixing unit 33, the adding unit 34, the switch 351, and the weight sensor 352, it can be used. Specifically, the operator first places a container 4 in the rice-holding area 311a, positioned at the switch 351. Then, using the various rice weights displayed on the control module 350, the operator can manually select the desired rice weight by pressing a button. Upon receiving the selection, the control module 350 will then adjust the output roller 331 accordingly. The weight sensor 352, the switch 351, and the adding unit 34 are linked. At this time, the rice placed in the storage tank 32 is turned by the rotation of the stirring rollers 332 and pushed to the output port 322 by the rotating blades 332b. It is then guided into the switch 351 by the output roller 331. The weight sensor 352 then senses the weight. If the sensed weight is incorrect, it immediately generates a signal, allowing the control module 350 to further activate the stirring rollers 352. 32. The discharge roller 331 is driven to discharge part of the rice in the accommodating space 320 and lead it through the output port 322 to the switch member 351 to replenish the insufficient weight of rice. Of course, when the weight sensor 352 senses that the weight of the rice entering the switch member 351 is appropriate, the weight sensor 352 will not generate any signal output. Then, the rice is placed into the corresponding container 4 through the switch member 351 in the open manner, thereby completing the rice output and supply for consumption.

[0012] Therefore, to prevent the large amount of rice placed in the storage tank 32 from clumping due to prolonged sitting, the stirring rollers 332 can rotate according to a preset setting, or when the control module 350 is pressed, the stirring rollers 332 can be activated to rotate, thereby maintaining a certain degree of looseness in the rice. At the same time, to prevent the rice from drying out during the stirring process, resulting in poor taste in subsequent servings, the container 341 can rotate according to a preset setting, or when the control module 350 is pressed. When group 350 is pressed, the conveyor 342 draws out the drinking water from container 341 and guides it into the hollow flow channel 332a of each mixing roller 332. As each mixing roller 332 rotates, the drinking water is sprayed out through the holes 332c. The sprayed drinking water is evenly incorporated into the rice during continuous mixing. Thus, when the automatic rice output machine 3 outputs rice for consumption, the rice is effectively kept in a proper moist state, thereby greatly improving the poor taste of the rice after mixing.

[0013] Referring to Figure 5, the second preferred embodiment of the present invention still includes the main components described in the previous embodiment, and the connection relationships between the components are the same as those described in the previous embodiment, which will not be repeated here. In particular, in order to ensure that the rice has a better palatable temperature when it is served for consumption, a heat preservation component 36 is provided on the base 311 in this embodiment. The heat preservation component 36 is located below the storage tank 32, and the heat preservation component 36 is connected to the control module 350 for appropriate drive control; therefore, when the automatic rice output machine 3 performs... Before use, the heat preservation element 36 can be preset to continuously generate an appropriate medium-high temperature state to transfer the appropriate medium-high temperature to the storage tank 32, so that the temperature of the rice in the storage tank 32 can be maintained at an appropriate temperature. In this way, whether it is the first time the rice is output for consumption or the last time the rice is output for consumption, the temperature of the rice can still be maintained as if it is freshly cooked, and the aroma of the rice will not be lost. It can also effectively maintain the moisture of the rice, thereby improving the taste of the rice.

[0014] In summary, the automatic rice output machine of the present invention utilizes a mixing unit where each mixing roller has a hollow flow channel, and each mixing roller has a plurality of blades and a plurality of holes arranged around its surface. Combined with an addition unit having a container for holding liquid, and assisted by a conveyor, the container is designed to communicate with the hollow flow channel. During the mixing roller's process of loosening the rice in the storage tank, the liquid introduced through the container can be evenly sprayed onto the rice through the holes. This prevents excessive moisture loss during mixing, thus avoiding the rice from drying out. Furthermore, the presence of a heat-insulating element on one side of the storage tank continuously generates a suitable medium-high temperature to maintain the appropriate temperature of the rice placed in the storage tank. This ensures that the temperature of the output rice remains as if it were freshly cooked, significantly improving the poor texture of the rice after mixing.

All simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the patent of the present invention.
