[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0014] The basic configuration of rice milling equipment will be described with reference to Figures 1, 2 and 6.

[0015] A partition wall 4 separates the building 1 into a guest room 2 where users enter and exit, and a machine room 3 where various parts of the rice milling equipment such as a rice milling machine 9 are installed.

[0016] A parking space S in which an electric vehicle C can be parked is provided on the side of the side wall 5 of the building 1.

[0017] An inlet 6a for a brown rice hopper 6 is provided on the guest room 2 side, into which brown rice brought by users is to be put. The inlet 6a for the brown rice hopper 6 is opened and closed by an opening / closing door 12 that moves up and down along the partition wall 4. Also provided on the guest room 2 side is a white rice tank 24 that stores polished white rice that has been polished by the rice polisher 9. A guest room door 11 is provided at the front of the guest room 2, through which users enter and exit.

[0018] The machine room 3 is equipped with an elevator 7 that lifts the brown rice fed into the brown rice feeding hopper 6, a stone remover 8 that sorts out foreign objects such as stones mixed in with the brown rice, and a rice polisher 9 that polishes the brown rice that has been stone-removed by the stone remover 8. At the rear of the machine room 3 is a bran storage section 10 that stores bran generated during the rice polishing process. On both the left and right sides of the bran storage section 10 are machine room doors 13 that allow the manager to enter and exit the machine room 3.

[0019] The partition wall 4 on the guest room 2 side is provided with a fee slot 14 for inserting fees, an operation panel 15 equipped with a polishing degree selection switch 21 for performing rice polishing operation, and a charging switch 22 for charging the electric vehicle C described below.

[0020] The configuration for supplying power to the electric vehicle C will be described.

[0021] A charging unit 16 for charging the electric vehicle C is provided on a side wall 5 of the building 1.

[0022] The charging unit 16 is installed in space A that penetrates the side wall 5 on the passenger compartment 2 side, and is configured to be opened and closed from the outside using an opening / closing lid 17. A socket 16a for a charging cable K for charging the battery of the electric vehicle C is provided in a position facing the outside of the building 1, and when a user opens the opening / closing lid 17, they can insert the charging cable K they have brought with them into the socket 16a. To supply power to the charging unit 16, as shown in Figure 9, a cord 36 for the charging unit 16 runs from the machine room 3 side through a space 40 between the ceiling 18 and roof 19 of the building 1, and is connected to the charging unit 16 by running it along the side wall 5 inside the passenger compartment 2. The portion that runs along the side wall 5 inside the passenger compartment 2 is covered with a cover 20.

[0023] By providing the charging unit 16 in the space A cut out from the side wall 5, it is possible to reduce the portion of the charging unit 16 that protrudes outside the building 1 or into the guest room 2, making it easier for users to charge the battery and operate the rice milling operation. In addition, the side wall 5 can be used to support the charging unit 16.

[0024] Building 1 is connected to a so-called three-phase 200V power supply.

[0025] 3 is a block diagram of the rice milling equipment, and input signals from a fee insertion detection sensor 35 that detects the fee, an input signal from a degree of polishing selection switch 21 that selects the degree of polishing, and an input signal from a charging switch 22 are input to the control unit 23. The control unit 23 outputs power supply signals to each part of the device, such as the rice milling machine 9, and to the charging unit 16.

[0026] Next, the rice milling operation and charging will be described with reference to FIG.

[0027] When the user deposits the fee into the fee slot 14, the door 12 opens and the user deposits brown rice into the slot 6a of the brown rice deposit hopper 6. Next, when the user selects the desired degree of polishing using the polishing degree selection switch 21, the various components of the equipment in the machine room 3 start up and the rice polishing operation begins.

[0028] The brown rice in the brown rice input hopper 6 is supplied by the elevator 7 to the stone removal machine 8 for stone removal. The brown rice that has been stone removed is then supplied by the elevator 7 to the rice polisher 9 for polishing. The polished white rice is stored in the polished rice tank 24, and the user puts the polished white rice in a bag that they brought with them to take home. Each part of the equipment in the machine room 3 stops when the time corresponding to the input fee has elapsed, or when a predetermined time has elapsed since the brown rice presence detection sensor 25 installed in the brown rice input hopper 6 detected the absence of brown rice. The bran generated during the rice polishing process is transported by the bran transport fan 26 to the bran storage section 10.

[0029] When charging an electric vehicle, the user inserts a charge into the charge slot 14, which opens the door 12, but when the user operates the charging switch 22, the door 12 closes.

[0030] Then, the user goes outside the building 1, opens the opening / closing cover 17, and inserts the charging cable K that he or she brought with him or her into the charging socket 16a to start charging. Charging continues for a period of time corresponding to the input fee.

[0031] According to this embodiment, rice milling operation and charging by the charging unit 16 can be performed using the same fee insertion slot 14 and operation panel 15, so that the configuration can be simplified.

[0032] Typically, the building 1 is installed in a location where there is a parking space S around it, so it is easy to use the space S around the building 1 to park the electric vehicle C and charge it.

[0033] Furthermore, by providing the charging unit 16 on the side wall 5 on the guest room 2 side, when the same user is performing rice milling operation and charging in parallel, it becomes easier to monitor both.

[0034] Next, various controls performed by the charging unit 16 will be described in detail.

[0035] Power is supplied from the electric power company via wiring to each part of the equipment, such as the rice milling machine 9, and to the charging unit 16, but along the way, relays (not shown) are provided to turn the power on and off for each part of the equipment and the charging unit 16, and each relay (not shown) is operated by a signal from the control unit 23. When a fee is inserted into the fee slot 14 and the charging switch 22 is operated, the corresponding relay is activated and power is supplied to each part of the equipment in the machine room 3 and to the charging unit 16.

[0036] By configuring the opening / closing lid 17 so that it can be opened and closed using an opening / closing motor (not shown), the opening / closing lid 17 opens when charging and closes when not charging, thereby preventing damage to the charging socket 16a due to tampering, etc.

[0037] A rainfall detection sensor 27 may be provided on the roof of the building 1, and when rain is detected, charging is disabled, thereby protecting the charging outlet 16a.

[0038] Next, a case where rice milling operation and charging are performed in parallel will be described with reference to FIG.

[0039] If you operate the charging switch 22 and insert a fee during rice milling operation, you can charge the battery while milling the rice. In this case, as shown in Figure 10, the fee for rice milling operation and the fee for charging are differentiated and subtracted from each other. The status of each operation is displayed on the display screen 28 on the operation panel 15. If you want to insert an additional fee while both rice milling operation and charging are in progress, operate the switch for the operation you want to add and then insert the fee, and the remaining time of that operation will increase.

[0040] During charging, rice milling can be performed in parallel with charging by putting brown rice into the brown rice input hopper 6 and selecting the degree of milling selection switch 21. In other words, when both the condition of the brown rice presence detection sensor 25 indicating the presence of brown rice and the condition of the degree of milling selection switch 21 being ON are met, rice milling can be started.

[0041] This allows the user to perform both rice milling and charging, improving convenience. In addition, when charging during rice milling, the user operates the charging switch 22 before inserting the charge, and while charging, the user operates the degree of polishing selection switch 21 before inserting the charge, making it possible to clearly distinguish between the charges.

[0042] When rice milling and charging are performed in parallel, the change is returned separately after each operation is completed. Alternatively, the change from the operation that is completed first can be applied by operating the other switch (the milling degree selection switch 21 or the charging switch 22).

[0043] This section explains the case where the charging unit 16 is equipped with specifications that allow both rapid charging and normal charging. Rapid charging requires a correspondingly larger amount of power to be supplied, which can lead to overload if rice milling is performed in parallel. Therefore, when rice milling and charging are performed in parallel, normal charging is used. Alternatively, if rice milling is performed during rapid charging, charging is switched from rapid charging to normal charging.

[0044] Next, an embodiment in which both rice milling operation and charging cannot be used at the same time will be described with reference to FIG.

[0045] When both rice milling and charging are performed in parallel, the amount of electricity used increases. Increasing the amount of electricity that can be used results in higher electricity bills, which is not desirable from the perspective of operating rice milling equipment.

[0046] Therefore, it is possible to operate only one of rice milling operation and charging.

[0047] Charging begins when the user operates the charging switch 22, inserts the charge, and then inserts the charging cable K into a designated location. After charging begins, charging continues for a time corresponding to the inserted charge, but a maximum charging time for one charge is set in advance, and charging ends when the maximum time is reached. If the amount of charge inserted exceeds the maximum time, change is returned through the change slot 29. For example, the maximum time is set to 15 minutes. Alternatively, if the user removes the charging cable K during charging, charging stops, and if there is change, the change is returned through the change slot 29.

[0048] When the user inserts the fee without operating the charging switch 22, the door 12 opens and the user inserts brown rice into the brown rice inserting hopper 6. When the user operates the degree of polishing selection switch 21, the rice polishing operation starts, and operation of the charging switch 22 is restricted during the rice polishing operation.

[0049] The rice milling operation time can be extended by checking the amount of brown rice in the brown rice charging hopper 6 during the rice milling operation, or by charging additional brown rice into the brown rice charging hopper 6 and paying an additional fee.

[0050] That is, the additional charge for charging exceeding the upper limit time is regulated, but the additional charge for rice milling operation is not regulated.

[0051] The rice milling operation is based on the amount of brown rice brought by the user. Also, the rice milling operation takes about 10 minutes for about 30 kg, so many customers mill for a relatively short time. In contrast, charging an electric vehicle takes more than 10 minutes, so it takes time.

[0052] If the charging time for an electric vehicle becomes longer, it will be inconvenient for users who operate the rice milling operation, but it is possible to take into consideration the convenience of users who operate the rice milling operation and users who charge the electric vehicle.

[0053] When the brown rice in the brown rice feeding hopper 6 runs out, the rice milling operation ends.

[0054] In this embodiment, quick charging is used.

[0055] Next, an example of how to attach the charging unit 16 will be described.

[0056] As shown in Fig. 8, the charging unit 16 is provided outside the side wall 5 of the guest room 2. Eaves 30 are provided on the roof of the rice milling equipment, and the charging unit 16 is covered from above by the eaves 30.

[0057] In addition, the charge slot 14 is provided adjacent to the charging unit 16. When a fare is inserted into this slot 14, it is determined that the charging unit 16 is being used, and the door 12 does not open, and charging can be performed without operating the charging switch 22. This allows the user to charge without entering the guest room 2, preventing erroneous operation of the rice milling operation and improving convenience. Alternatively, if a card reader 31 for a membership card, credit card, or the like is provided, and charging is performed using the card reader 31, charging can be started by simply inserting the charging cable K without using the charging switch 22 in the guest room 2.

[0058] An electric display board 32 displaying messages such as "Rice milling in progress" and "Charging" can be installed on the front side of the building 1, allowing users to see the message from a distance. The control unit 23 may also be connected to the Internet via communication so that the current usage status can be confirmed via the Internet.

[0059] Next, FIG. 11 shows a configuration that allows the rice milling equipment manager to perform setting operations to efficiently utilize rice milling operation and charging.

[0060] In particular, rice milling operations have busy and slow seasons depending on the season and time of day, depending on the region.

[0061] Therefore, a screen 50 is provided that allows the rice milling equipment manager to set preferences for rice milling operation or charging. The items on the screen can be changed using the touch panel or a separate button, etc.

[0062] Figure 11 (a) shows that priority periods and time zones have been set for rice milling operation and charging. From 10:00 to 17:00, only rice milling operation is possible, and charging is restricted. From 19:00 to 22:00, only charging is possible, and rice milling operation is restricted. During other time zones, both are possible. (b) is set up so that it can mill rice and charge at all times. (C) is set so that only charging can be performed every Saturday and every Sunday, and rice milling operation is recorded.

[0063] In this way, the system is configured so that the administrator can set the rice milling equipment as desired to suit the circumstances of the area where the equipment is installed.

[0064] Although the charging unit 16 in this embodiment is described as a type into which a charging cable K brought by a user is plugged, the charging unit 16 may be a type in which the charging cable K is mounted on the building 1 side. In this case, the charging cable plug is provided on the outside of the side wall 5 of the building 1, thereby enabling smooth charging operations. [Explanation of symbols]
