Description

[Technical Field]

[0001] The present invention relates to a display device and a fermentation treatment system including the same. [Background technology]

[0002] Conventionally, various food waste treatment devices that use microorganisms to decompose food waste have been proposed (see, for example, Patent Document 1). Food waste treatment devices are generally provided with an input unit (for example, a button) that instructs the device to start and stop operation. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-110514 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, touch panels have become widely used as a means of inputting information to devices. A display device is constructed by placing a touch panel on a display unit, and selectable items are displayed on the display unit. A user can input an instruction to select a desired item by pressing an area of ​​the touch panel that corresponds to the desired item displayed on the display unit.

[0005] However, when the above-described display device is applied to a food waste processing device, if there are multiple types of people who can input something (hereinafter also referred to as "inputters"), and all items are displayed on the display unit regardless of the type of inputter, the following problems arise. For example, a user of the food waste processing device will have difficulty finding an item that they can select from all the displayed items, and will be unable to easily and quickly select and input an item. In addition, a user may mistakenly select an item that can only be selected by someone other than the user (for example, a maintenance person). A display method that causes an inputter to make an incorrect selection is not user-friendly for the inputter, and therefore must be avoided.

[0006] The present invention has been made to solve the above problems, and its purpose is to provide a display device that enables easy, quick, and accurate selection and input of items for each type of inputter, and a fermentation processing system equipped with such a display device. [Means for solving the problem]

[0007] A display device according to one aspect of the present invention comprises a display unit, an input unit that accepts input from an inputter, and a display control unit that controls the display of the display unit based on the input, wherein the display control unit displays on the display unit a list of items that is determined according to the type of inputter input by the input unit and that the inputter of that type can select by the input unit.

[0008] A fermentation processing system according to another aspect of the present invention comprises the above-described display device and a fermentation processing machine that ferments the material to be processed, and the display control unit of the display device controls the display of the display unit and controls the operation of the fermentation processing machine based on the input by the inputter. [Effects of the Invention]

[0009] According to the above configuration, it is possible for each type of person entering information to easily, quickly and accurately select and input items. [Brief explanation of the drawings]

[0011] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. In this specification, the axial direction of the rotating shaft 2 shown in FIG. 2, i.e., the direction in which the axis Ax of the rotating shaft 2 extends, is referred to as the left-right direction. The left-right direction is parallel to a horizontal plane. The direction perpendicular to the left-right direction in the horizontal plane is referred to as the front-rear direction, and the direction perpendicular to the horizontal plane is referred to as the up-down direction. Here, the front-rear, left-right, and up-down directions are defined by defining the side where the inlet 4 for the material to be treated is located relative to the rotating shaft 2 when the fermentation processor 100 shown in FIG. 2 is placed on a surface parallel to the horizontal plane as the "front." Furthermore, the circumferential direction and radial direction when the rotating shaft 2 rotates based on the axial direction may be simply referred to as the circumferential direction and the radial direction, respectively.

[0012] In the drawings, the X direction is the left-right direction, the Y direction is the front-to-back direction, and the Z direction is the up-to-down direction. The +X side (the tip of the arrow) is the left side in the left-to-right direction, the +Y side is the front side in the front-to-back direction, and the +Z side is the upper side in the up-to-down direction. The above definitions of each direction are used merely for the purpose of explanation in this specification, and the directions and positional relationships during actual use are not limited to the directions defined above and the positional relationships based thereon.

[0013] In this specification, the term "switch" refers to a mechanical switching mechanism, and includes, for example, a push button that is accompanied by a mechanical movement.

[0014] [1. Fermentation treatment system] FIG. 1 is a perspective view showing the appearance of a fermentation treatment system 500 of this embodiment. The fermentation treatment system 500 is configured by incorporating a display device 300 into a fermentation treatment machine 100. The fermentation treatment machine 100 is a device that treats materials to produce compost, soil conditioners, etc. The materials to be treated are, for example, food waste generated in homes or stores, but may also be livestock manure (cattle excrement). When treating the materials to be treated, it is preferable to mix microorganisms with the materials to promote fermentation of the materials to be treated. For example, aerobic bacteria are preferably used as the microorganisms.

[0015] The display device 300 displays various types of information. In this embodiment, information such as the operating time of the fermentation processor 100 and the weight of the material to be processed is displayed on the display device 300. The display device 300 is configured, for example, as a display device with a touch panel. A user of the fermentation processing system 500 can check the operating status of the fermentation processor 100 by looking at the information displayed on the display device 300. Furthermore, the user can also operate the touch panel of the display device 300 to switch the display screen and check the desired information as needed.

[0016] As described above, the fermentation treatment system 500 of this embodiment includes the display device 300 and the fermentation treatment machine 100 that ferments the material to be treated. The fermentation treatment machine 100 and the display device 300 will be described in detail below.

[0017] [2. Fermentation treatment machine] As shown in Fig. 1, the fermentation processor 100 includes a main body 101 and an equipment installation section 102 located on the left side of the main body 101. In the main body 101, processing of the material to be processed (fermentation and composting) is carried out. In the equipment installation section 102, various pieces of equipment necessary for processing the material to be processed in the main body 101 are arranged.

[0018] FIG. 2 is a diagram of the fermentation processor 100 shown in FIG. 1 with some components removed. In detail, FIG. 2 is a diagram of the fermentation processor 100 shown in FIG. 1 with the lid 1011, equipment cover 1021, and control box 1022 removed. The lid 1011 is attached to the main body cover 1012 of the main body 101, and enables the cover opening 1012a of the main body cover 1012 to be opened and closed. The equipment cover 1021 covers some of the equipment placed in the equipment placement section 102. The control box 1022 is located on the front side of the equipment placement section 102. The above-mentioned display device 300 is mounted on the control box 1022.

[0019] As shown in FIG. 2, the main body 101 includes a fermenter 1, a rotating shaft 2, and a plurality of stirring claws 3.

[0020] The fermenter 1 is a tank in which the material to be treated is fermented. The fermenter 1 is covered with a main body cover 1012. In this embodiment, the fermenter 1 has a cylindrical tube portion 11 extending in the left-right direction, and a left wall portion 12a and a right wall portion 12b disposed at both left and right ends of the tube portion 11. The left wall portion 12a and the right wall portion 12b are plate-shaped and extend in the Y and Z directions. A tube portion opening 11a is provided on the outer circumferential surface of the tube portion 11, penetrating the tube portion 11 in the radial direction. The tube portion opening 11a and the cover opening 1012a overlap in the radial direction to form an inlet 4 through which the material to be treated is introduced into the fermenter 1. The inlet 4 is opened and closed by a lid portion 1011. The inlet 4 is also used to remove the material to be treated from the fermenter 1. That is, a user can introduce and remove the material to be treated into and from the fermenter 1 through the inlet 4.

[0021] An emergency cover 1012a is provided on the lower front side of the main body cover 1012. For example, if an abnormality occurs in the fermentation processor 100 and it is necessary to quickly remove the material to be treated from the fermenter 1, the cover 1012a can be opened to expose an opening (not shown) located below the cylindrical opening 11a of the fermenter 1, allowing the material to be removed from the fermenter 1.

[0022] The rotating shaft 2 is located inside the fermenter 1. The rotating shaft 2 is a cylindrical shaft extending in the left-right direction. The rotating shaft 2 rotates around an axis Ax extending in the left-right direction. In this embodiment, the rotating shaft 2 rotates clockwise around the axis Ax when viewed from the +X direction side. The left end of the rotating shaft 2 is rotatably supported by the left wall portion 12a. The right end of the rotating shaft 2 is rotatably supported by the right wall portion 12b.

[0023] The multiple agitator claws 3 are arranged on the rotating shaft 2. More specifically, the multiple agitator claws 3 are arranged on the outer peripheral surface of the rotating shaft 2. At least some of the multiple agitator claws 3 are arranged on the rotating shaft 2 with gaps in the left-right direction. The multiple agitator claws 3 are fixed to the rotating shaft 2 so that their tips (ends opposite the side fixed to the rotating shaft 2) are positioned offset in the circumferential direction of the rotating shaft 2 when viewed from the +X direction. The multiple agitator claws 3 rotate together with the rotating shaft 2 and agitate the material to be treated in the fermenter 1. In the fermentation processor 100, the material to be treated in the fermenter 1 is fermented and dried while being agitated by the agitator claws 3, thereby obtaining a desired product such as compost or a soil conditioner.

[0024] The equipment installation section 102 is equipped with an agitation motor 5, an intake blower 6, and a filter section 7. The agitation motor 5 is a drive source for rotating the rotary shaft 2 to agitate the material to be treated with the agitation claws 3. The agitation motor 5 is driven by a motor inverter 5a (see FIG. 5). The rotational output of the agitation motor 5 is transmitted to the rotary shaft 2 via a power transmission mechanism 8 including a power transmission means such as gears.

[0025] The intake blower 6 is an air blowing device that supplies gas into the fermenter 1, and is driven by a blower inverter 6a (see FIG. 5). In this embodiment, the gas is air. The air sent out from the intake blower 6 is introduced into the fermenter 1 from the left wall portion 12a of the fermenter 1 via the air supply path 9. By supplying air into the fermenter 1, oxygen can be appropriately supplied to microorganisms (e.g., aerobic bacteria) in the fermenter 1. This promotes fermentation processing by the microorganisms in the fermenter 1.

[0026] The air in the fermenter 1 is sent from the left wall 12a of the fermenter 1 to the filter unit 7 via the exhaust path 10. The air sent to the filter unit 7 enters the filter unit 7 from the lower part thereof, passes through a filter (not shown) placed inside that removes foreign matter, and is exhausted to the outside of the filter unit 7 from the upper part thereof. The air exhausted to the outside of the filter unit 7 is sent to a deodorizing device (not shown), where it is subjected to a deodorizing treatment and released into the atmosphere. The deodorizing device may be placed inside or outside the fermentation processor 100.

[0027] An opening / closing door D1 is provided on the front of the control box 1022 shown in Fig. 1. A colorless or colored transparent window Dw is provided in the opening / closing door D1 at a position in front of the display device 300. Therefore, when the opening / closing door D1 is closed, the user can see the information displayed on the display device 300 through the window Dw. In addition, an opening / closing door D2 is provided on the main body cover 1012 of the main body 101. Fig. 3 shows the appearance of the fermentation processing system 500 with the opening / closing doors D1 and D2 of Fig. 1 open.

[0028] When the opening / closing door D1 is opened, the display device 300 and the first emergency stop switch SW1 provided on the control box 1022 are exposed. This allows the user to perform some kind of pressing input on the display device 300 with a touch panel. Furthermore, if it is necessary to stop the operation of the fermentation treatment machine 100 immediately, for example, when an abnormality occurs in the fermentation treatment machine 100, the user can stop the operation of the fermentation treatment machine 100 under the control of the control unit 330 by pressing the first emergency stop switch SW1 (also referred to as the "control box side emergency stop switch").

[0029] A second emergency stop switch SW2 (also referred to as the "operation box-side emergency stop switch") is provided on the upper side of the opening / closing door D2 of the main body cover 1012. The user can also stop the operation of the fermentation processor 100 under the control of the control unit 330 by pressing the second emergency stop switch SW2. Here, the second emergency stop switch SW2 is not covered by the opening / closing door D2 of the main body cover 1012 and is exposed to the outside. Therefore, in the event of an emergency, the user can immediately stop the operation of the fermentation processor 100 by directly pressing the second emergency stop switch SW2 without performing the operation to open the opening / closing door D2.

[0030] When the opening / closing door D2 is opened, the buzzer stop switch SW3, the operation start switch SW4, and the operation stop switch SW5 provided on the main body 101 are exposed. The buzzer stop switch SW3, the operation start switch SW4, and the operation stop switch SW5 are located in this order from top to bottom, but this positional relationship is not limited to this. By pressing the buzzer stop switch SW3, the user can temporarily stop the buzzer BZ (see FIG. 5) of the fermentation treatment machine 100 from sounding in an emergency. In addition, the user can start the operation of the fermentation treatment machine 100 by pressing the operation start switch SW4. Furthermore, the user can stop the operation of the fermentation treatment machine 100 by pressing the operation stop switch SW5. Note that the buzzer BZ sounding and the start and stop of the operation of the fermentation treatment machine 100 are controlled by the control unit 330.

[0031] [3.Display device] FIG. 4 is an exploded perspective view showing a schematic configuration of the display device 300. The display device 300 has a display unit 310, an input unit 320, and a control unit 330. The display unit 310 is, for example, a liquid crystal display device, and displays information about the operating state of the fermentation processor 100, setting values, buttons for pressing inputs, and the like. The input unit 320 is, for example, a touch panel, and is placed in front of the display unit 310 and receives inputs from an inputter. In this embodiment, the inputter includes not only a user who actually uses the fermentation processor 100 by operating the display device 100, but also a maintenance person and a developer. Note that a maintenance person is a person (e.g., a serviceman) who performs maintenance such as part replacement on the fermentation processor 100. Furthermore, a developer is a person involved in the development and design of the fermentation processor 100 (e.g., a person belonging to the manufacturer).

[0032] The control unit 330 is a display control unit that controls the display on the display unit 310. In particular, the control unit 330 controls the display on the display unit 310 based on an input from the input unit 320 by a user. Such a control unit 330 is configured, for example, with a central processing unit called a CPU (Central Processing Unit). Note that the control unit 330 may be configured with a storage unit such as a RAM (Random Access Memory) or a ROM (Read Only Memory).

[0033] For example, when a plurality of items are displayed on the display unit 310 and the inputter presses an area of ​​the input unit 320 that overlaps with a desired display item, a detection signal of the pressed position is sent from the input unit 320 to the control unit 330. This allows the control unit 330 to recognize that the inputter has made an input to select the desired display item, based on the detection signal and the position information of the display items on the display unit 310. The control unit 330 also controls the operation of each part of the fermentation processor 100. Therefore, the control unit 330 can control each part of the fermentation processor 100 based on the recognition result of the selection input by the inputter.

[0034] That is, the display device 300 of this embodiment includes a display unit 310, an input unit 320 that accepts input from a user, and a control unit 330 (display control unit) that controls the display of the display unit 310 based on the input.

[0035] Furthermore, the control unit 330 of the display device 300 in the fermentation treatment system 100 controls the display on the display unit 310 based on input by the person making the input, and also controls the operation of the fermentation treatment machine 100. Through such control by the control unit 330, the person making the input can operate the fermentation treatment machine 100 under desired operating conditions by operating the input unit 320 on the display device 300 side.

[0036] 4. Hardware configuration of the fermentation processing system 5 is a block diagram showing the hardware configuration of a fermentation treatment system 500 of this embodiment. In addition to the above-mentioned stirring motor 5 and intake blower 6, the fermentation treatment machine 100 is equipped with an intake heater BH, a first tank heater TH1, a second tank heater TH2, a buzzer BZ, and a signal tower SL. Note that the first tank heater TH1 and the second tank heater TH2 may be collectively referred to simply as the "tank heaters."

[0037] The intake heater BH heats the air supplied into the fermenter 1 by the intake blower 6. By supplying heated air into the fermenter 1, the temperature inside the fermenter 1 approaches a temperature suitable for fermentation of the material to be treated by microorganisms, thereby promoting fermentation of the material to be treated. Electricity is supplied to the intake heater BH by an intake heater switch BHa. The intake heater switch BHa is controlled by the control unit 330.

[0038] The first tank heater TH1 and the second tank heater TH2 are arranged side by side in the left-right direction below the fermenter 1 and heat the fermenter 1. By heating the fermenter 1 with the first tank heater TH1 and the second tank heater TH2, the materials to be treated in the fermenter 1 are heated to a temperature suitable for fermentation, and fermentation of the materials to be treated is promoted. Power is supplied to the first tank heater TH1 and the second tank heater TH2 by a first tank heater switch TH1a and a second tank heater switch TH2a, respectively. The first tank heater switch TH1a and the second tank heater switch TH2a are controlled by the control unit 330.

[0039] The buzzer BZ emits a buzzer sound if an abnormality occurs in the fermentation treatment machine 100. The signal tower SL notifies the outside of the operating status of the fermentation treatment machine 100 by lighting three colored lamps: red (R), yellow (Y), and green (G). The R lamp lights up, for example, if an abnormality occurs in the fermentation treatment machine 100. The Y lamp lights up, for example, when the fermentation treatment machine 100 stops operating. The G lamp lights up, for example, when the fermentation treatment machine 100 is operating. The operation (alert, lighting) of the buzzer BZ and signal tower SL is controlled by the control unit 330.

[0040] Next, various switches and sensors provided in the fermentation processor 100 will be described. In addition to the first emergency stop switch SW1, second emergency stop switch SW2, buzzer stop switch SW3, operation start switch SW4, and operation stop switch SW5 described above, the fermentation processor 100 also includes an inlet open / close switch SW0, a first tank heater temperature sensor TH1s, a second tank heater temperature sensor TH2s, an intake air temperature sensor BHs, a product temperature sensor Gs, an exhaust pressure sensor EPs, an outside air temperature sensor OTs, an outside air humidity sensor OHs, an electric energy sensor Es, and a weight sensor Ws. Signals detected by the above switches and sensors are output to the control unit 330.

[0041] The drop slot opening / closing switch SW0 is a switch (button) that switches depending on whether drop slot 4 is opened or closed by lid 1011. For example, when lid 1011 is open, the drop slot opening / closing switch SW0 is released from pressure by lid 1011. In this case, drop slot opening / closing switch SW0 is turned OFF. On the other hand, when lid 1011 is closed, drop slot opening / closing switch SW0 is pressed by lid 1011 and turned ON.

[0042] The first tank heater temperature sensor TH1s detects the temperature of the first tank heater TH1. The second tank heater temperature sensor TH2s detects the temperature of the second tank heater TH2. The intake air temperature sensor BHs detects the temperature of the air supplied into the fermenter 1 by the intake air blower 6. The product temperature sensor Gs detects the temperature of the material to be treated in the fermenter 1. These temperature sensors are composed of, for example, thermocouples, but may also be composed of other sensors (resistance temperature detectors, thermistors, non-contact temperature sensors, etc.).

[0043] The exhaust pressure sensor EPs is disposed in the exhaust path 10 (see FIG. 2) and detects the pressure of the air exhausted from the fermenter 1. The outside air temperature sensor OTs and the outside air humidity sensor OHs detect the temperature and humidity, respectively, of the environment in which the fermentation treatment machine 100 is installed (outside the fermentation treatment machine 100). The power amount sensor Es detects the amount of power consumed by the fermentation treatment machine 100.

[0044] The weight sensor Ws measures the weight of the fermenter 1. For example, by measuring the weight of the fermenter 1 before the materials to be treated are added and the weight of the fermenter 1 after the materials to be treated are added using the weight sensor Ws and calculating the difference between the weights, the weight of the materials to be treated added to the fermenter 1 can be calculated. Furthermore, by having the weight sensor Ws measure the weight of the fermenter 1 over the course of treatment time for the materials to be treated, it is possible to determine the degree of drying of the materials to be treated in the fermenter 1 (the progress of drying) based on the change in weight. Such a weight sensor Ws includes, for example, a load cell and a weighing indicator that amplifies a load signal from the load cell, performs AD conversion, and converts it into a weight value.

[0045] The fermentation processor 100 further includes a timing unit TI. The timing unit TI is composed of a timer that measures various times (for example, the time elapsed since the fermentation processor 100 started operating). The time information measured by the timing unit TI is output to the control unit 330. The timing unit TI may be built into the control unit 330.

[0046] [5. Display screen of display device] Next, the switching control of the display screen of the display unit 310 based on the input operation of the input unit 320 in the display device 300 of this embodiment will be described.

[0047] Fig. 6 shows an example of a home screen displayed on the display unit 310 of the display device 300. In Fig. 6, a list of items that can be selected by a user using the fermentation processor 100 (display device 300) via the input unit 320 is displayed on the display unit 310. In the example of Fig. 6, three items, "operation monitor," "error display," and "removal," are displayed on the display unit 310 as items that can be selected by the user. Details of the content of each display item will be described later.

[0048] In this embodiment, the control unit 330 as a display control unit is determined according to the type of inputter inputted by the input unit 320, and causes the display unit 310 to display a list of items that can be selected by the inputter of the above type by the input unit 320. More specifically, this is as follows.

[0049] In the following description, "pressing" refers to pressing an area of ​​input unit 320, which is configured as a touch panel, that overlaps with a display item displayed on display unit 310. Furthermore, the above-mentioned "inputter" who presses input on input unit 320 here refers to any one of the above-mentioned three parties: the user, the maintenance person, and the developer.

[0050] For example, when the person inputting data presses the display item "Maintenance Switch" on the display screen shown in FIG. 6, the control unit 330 causes the display unit 310 to display a passcode input screen (pop-up display) superimposed on the display screen of FIG. 6, as shown in FIG. 7. If the person inputting data is, for example, a maintenance person, the maintenance person operates the numeric keypad to input his / her own pre-registered passcode and finally presses the "Complete" button. Then, the maintenance person is designated as the person inputting data, and the control unit 330 causes the display unit 310 to display the screen shown in FIG. 8 in accordance with the designation of the person inputting data. In FIG. 8, a list of items that the maintenance person can select using the input unit 320 is displayed. Specifically, in addition to the items that the user can select (the three items "Operation Monitor," "Error Display," and "Removal"), the items "Forced Drive," "Extended Monitor," "Operation Data," and "Settings" are displayed on the display unit 310 as items that the maintenance person can select.

[0051] When a maintenance person is designated as the input person, the maintenance person operates the input unit 320 to give or input various instructions, which is also referred to as "simple maintenance." Furthermore, the screen displayed on the display unit 310 when a maintenance person is designated as the input person is also referred to here as the "simple maintenance screen" (in FIG. 8 etc., "simple maintenance" is displayed in the upper right corner of the display screen).

[0052] On the display screen shown in Fig. 7, if the person inputting the information is, for example, a developer, the developer operates the numeric keypad to input his / her own pre-registered passcode and finally presses the "Done" button. Then, the developer is designated as the person inputting the information, and the control unit 330 causes the display unit 310 to display the screen shown in Fig. 9 in accordance with the designation of the person inputting the information. In Fig. 9, a list of items that the developer can select using the input unit 320 is displayed.

[0053] When a developer is designated as an input person, the developer operates the input unit 320 to give various instructions or input, which is also referred to as "detailed maintenance." Furthermore, the screen displayed on the display unit 310 when a developer is designated as an input person is also referred to here as the "detailed maintenance screen" (in FIG. 9 etc., "detailed maintenance" is displayed in the upper right corner of the display screen).

[0054] As shown in Figures 8 and 9, the display items on the home screen are the same on the simple maintenance screen and the detailed maintenance screen. However, when a desired display item on the home screen is pressed to transition to the next screen, the simple maintenance screen is configured so that it is not possible to input various setting values ​​that only developers can enter on the detailed maintenance screen. In this respect, the simple maintenance and detailed maintenance screens are distinguished, and the simple maintenance and detailed maintenance screens are distinguished.

[0055] The color of the header section H1 at the top of the home screen is different between the simple maintenance screen and the detailed maintenance screen. For example, the header section H1 is blue in the home screen of FIG. 8, and green in the home screen of FIG. 9 (in the drawings, the difference in display color is indicated by different types of hatching). This allows the simple maintenance screen and the detailed maintenance screen to be clearly distinguished (even if the displayed items are the same). Furthermore, the user can intuitively recognize that the simple maintenance screen and the detailed maintenance screen are different.

[0056] When transitioning from the simple maintenance screen of FIG. 8 or the detailed maintenance screen of FIG. 9 to the screen shown in FIG. 6, the inputter (user) presses the display item "Maintenance switch" on the display screen, causing the passcode input screen shown in FIG. 7 to pop up on the display unit 310. The user inputs their own pre-registered passcode using the numeric keypad and finally presses the "Complete" button, thereby designating the user as the inputter, and the control unit 330 causes the display unit 310 to display the screen shown in FIG. 6 in accordance with the designation of the inputter. Note that the screen displayed on the display unit 310 when the user is designated as the inputter is also referred to as the "user screen" here. In this embodiment, when the fermentation processing system 500 is powered on, it is assumed that the user is designated as the inputter by default, and the user screen of FIG. 6 is displayed by default.

[0057] In this embodiment, a list of items determined according to the type of inputter is displayed on the display unit 310 (see FIGS. 6, 8, and 9). Moreover, the list of items is a list of items that can be selected by the inputter of the specified type using the input unit 320. This allows any type of inputter to intuitively and easily grasp the items that they can select by looking at the display unit 310, and instantly select a desired item by pressing the input unit 320.

[0058] For example, a user can immediately recognize from the display screen of Fig. 6 that only three items, "Operation Monitor," "Error Display," and "Removal," are selectable, and can immediately select any of them. Furthermore, a maintenance person and a developer (hereinafter collectively referred to as "maintenance person, etc.") can immediately recognize that a total of seven items, including four items such as "Forced Drive" in addition to the three items selectable only by the user, are selectable, and can immediately select any of them. Therefore, selection and input of items can be performed easily and quickly depending on the type of inputter.

[0059] Furthermore, items such as "forced drive" and "extended monitor" can only be selected by inputters other than the user (such as maintenance personnel), and are not displayed on the display screen when a user is designated as the inputter (see FIG. 6). Therefore, when a user is designated as the inputter, it is possible to prevent the user from selecting an item on the user screen that can only be selected by maintenance personnel, etc., by mistake. This makes it possible to accurately select and input items for each type of inputter.

[0060] In other words, when the input unit 320 specifies a user using the display device 300 as the type of inputter, the control unit 330 as a display control unit causes the display unit 310 to display a list of items that the user can select, while hiding items that can only be selected by other types of inputters on the display unit 310 (see Figure 6).

[0061] This control allows the user as the inputter to easily understand the items that he or she can select by looking at the display unit 310. Furthermore, items that can only be selected by other types of inputters (such as maintenance personnel) (for example, "forced drive") are hidden on the display unit 310, so the user cannot select items that can only be selected by maintenance personnel, etc., using the input unit 320. This reliably prevents the user from erroneously selecting an item that is not relevant to the user using the input unit 320.

[0062] In this embodiment, on the home screen displayed on the display unit 310, items that can only be selected by the user are displayed as buttons with a bright background under the control of the control unit 330. For example, in FIG. 6 and other figures, the items "Driving Monitor," "Error Display," and "Removal" are displayed on the display unit 310 as a composite image 311 obtained by combining a text portion 311a with a background portion 311b. The text portion 311a is the portion that displays the text "Driving Monitor," "Error Display," and "Removal," and is, for example, black. The background portion 311b is the portion that forms the background of the text portion 311a and is, for example, white. Note that the color of the background portion 311b may be any color brighter than the color of the text portion 311a, and is not limited to the above-mentioned white. In other words, the color of the background portion 311b may be set to a color brighter than the color of the text portion 311a.

[0063] 8 and 9, the items selectable only by maintenance personnel, etc. ("Forced Drive," "Extended Monitor," "Operational Data," and "Settings") are displayed on the display unit 310 as a composite image 312 obtained by combining a text portion 312a with a background portion 312b. The text portion 312a is the portion that displays text such as "Forced Drive," and is colored, for example, white. The background portion 312b is the portion that forms the background of the text portion 312a and is colored, for example, blue. Note that in FIGS. 6, 8, and 9, the background portion 313 of the entire home screen is displayed, for example, in gray.

[0064] In this way, control unit 330 as a display control unit causes display unit 310 to display items selectable by the user as composite image 311 obtained by combining text portion 311a indicating the content of the item with background portion 311b. At this time, the brightness of background portion 311b in composite image 311 is higher than the brightness of text portion 311a. This makes it easier for the user to intuitively recognize the items displayed on display unit 310, and enables the user to easily and accurately select a desired item from the list of displayed items.

[0065] Furthermore, on the home screen, a group of items that can be selected by a user when the user is designated as the inputter via the input unit 320 is referred to as a first group of items G1. Specifically, the items included in the first group of items G1 are three items: "Operation Monitor," "Error Display," and "Removal," as shown in FIG. 6. On the other hand, a group of items that can be selected only by a maintenance person or the like when the maintenance person or the like is designated as the inputter is referred to as a second group of items G2. Specifically, the items included in the second group of items G2 are four items: "Forced Drive," "Extended Monitor," "Operation Data," and "Settings," as shown in FIGS. 8 and 9. Note that the "Maintenance Switch" button is excluded from the first group of items G1 and the second group of items G2.

[0066] In this embodiment, when a maintenance person or the like is selected and specified by the input unit 320, the control unit 330 controls the display unit 310 to display both the first item group G1 and the second item group G2. That is, when a type other than a user is specified by the input unit 320, the control unit 330 as a display control unit causes the display unit 310 to display the first item group G1 and the second item group G2. In this case, the first item group G1 includes items that can be selected by the user. On the other hand, the second item group G2 includes items that can only be selected by inputters of a type other than a user.

[0067] Even when a type other than a user (such as a maintenance person) is specified by the input unit 320, the first item group G1 is displayed on the display unit 310, just as when a user is specified as the input person. This allows the maintenance person to select items included in the first item group G1, i.e., items selectable by the user, using the input unit 320. This allows the maintenance person to check, maintain, and set (hereinafter also referred to as "check, etc.") the items selectable by the user. Furthermore, because the second item group G2 is also displayed on the display unit 310 in addition to the first item group G1, the maintenance person can select items included in the second item group G2 using the input unit 320 and check, etc., the items.

[0068] 8 and 9, in this embodiment, on the home screen, items selectable by the user are displayed larger on the display unit 310 than items selectable only by maintenance personnel, etc. In other words, the control unit 330, which functions as a display control unit, causes the items included in the first item group G1 to be displayed larger on the display unit 310 than the items included in the second item group G2. This allows maintenance personnel, etc., to distinguish between items selectable by the user and items selectable only by maintenance personnel, etc., by their size. This makes it possible to further reduce erroneous selection of items by maintenance personnel, etc., between the first item group G1 and the second item group G2.

[0069] As described above, in the composite image 311 showing each item (such as "Driving Monitor") included in the first item group G1, the text portion 311a is, for example, black, and the background portion 311b is, for example, white. On the other hand, in the composite image 312 showing each item (such as "Forced Drive") included in the second item group G2, the text portion 312a is, for example, white, and the background portion 312b is, for example, blue.

[0070] That is, the text colors (the text colors of text portions 311a and 312a) of the items included in the first item group G1 and the items included in the second item group G2 are different from each other. Furthermore, the background colors (the text colors of background portions 311b and 312b) of the items included in the first item group G1 and the items included in the second item group G2 are also different from each other. Thus, in this embodiment, both the text colors and the background colors of the items included in the first item group G1 and the items included in the second item group G2 are different from each other. The text colors of the items included in the first item group G1 and the items included in the second item group G2 may be the same color and only the text colors may be different, or the text colors may be the same color and only the background colors may be different.

[0071] In other words, the control unit 330, which functions as a display control unit, causes the items included in the first item group G1 and the items included in the second item group G2 to be displayed on the display unit 310 with at least one of the text color and the background color being different from each other. This makes it easy for maintenance personnel to visually distinguish and recognize items that can be selected by the user from items that can only be selected by maintenance personnel. This makes it easy to reduce erroneous selection of items by maintenance personnel between the first item group G1 and the second item group G2.

[0072] In this embodiment, composite image 311 has frame portion 311c (see FIGS. 6, 8, and 9), and composite image 312 has frame portion 312c (see FIGS. 8 and 9). Frame portions 311c and 312c are portions that emphasize the peripheries of composite images 311 and 312. Frame portion 311c is displayed in a color (e.g., light gray) that is different from background portion 311b and background portion 313 of the entire screen. Frame portion 312c is also displayed in a color (e.g., light blue) that is different from background portion 312b and background portion 313 of the entire screen. For convenience, in each drawing, frame portions 311c and 312c are shown with double border lines.

[0073] Composite image 311 is an image showing at least items selectable by the user (such as "operation monitor"). On the other hand, composite image 312 is an image showing items selectable only by maintenance personnel (such as "forced drive"). Therefore, in this embodiment, it can be said that control unit 330, which functions as a display control unit, causes display unit 310 to display items selectable by the input user as composite image 311 (or 312) having frame 311c (or 312c) with an emphasized outer periphery. This allows the input user to look at display unit 310 and easily find an item selectable by the user using frame 311c or 312c as a clue. This enables easy and quick selection and input of a desired item using input unit 320.

[0074] In addition, on the display unit 310, even on screens other than the home screen, items that can be selected by the user are displayed as images with frames that highlight the periphery, and in the drawings, items that can be selected by the user are indicated by double borders (double solid lines or double dashed lines). In other words, items that are not indicated by double borders in the drawings indicate items that cannot be selected by the user (for example, parts that are simply displayed).

[0075] [6. About the transition of display screens] Next, a description will be given of the transition of the display screen when an item is selected using the input unit 320. Fig. 10 schematically shows the hierarchical relationship of the items displayed on the display unit 310. The transition of the display screen basically occurs from left to right in the figure (unless the home button H2 (see Fig. 11) described later is pressed). In other words, the left side of the figure is the upper layer, and the right side of the figure is the lower layer.

[0076] As described above, the home screen of FIG. 6 displays three items ("Operation Monitor," "Error Display," and "Remove") and a "Maintenance Switch" button. When the user selects one of these items using the input unit 320, the control unit 330 causes the display unit 310 to display a details screen of the selected item. Also, the home screens of FIGS. 8 and 9 display seven items ("Operation Monitor," "Error Display," "Remove," "Forced Drive," "Extended Monitor," "Operation Data," and "Settings") and a "Maintenance Switch" button. When a maintenance person or the like selects one of these items using the input unit 320, the control unit 330 causes the display unit 310 to display a details screen of the selected item.

[0077] As shown in FIG. 10, of the multiple items displayed on the home screen, five items, "Error Display," "Forced Drive," "Extended Monitor," "Operational Data," and "Settings," have multiple display items further down. Details of the display items in the lower layers will be described later. The above five items are referred to as hierarchical items here. In other words, the items displayed on the display unit 310 include hierarchical items ("Error Display," "Forced Drive," "Extended Monitor," "Operational Data," and "Settings") that have a hierarchical structure.

[0078] Below, each display screen to which the home screen is transitioned will be described. Note that the display screen when "Maintenance Switch" is selected on the home screen is as shown in FIG. 7, so below, a display screen when an item other than "Maintenance Switch" is selected will be described. Note that in the following description, pressing an area of ​​input unit 320 that is positioned overlapping an item or button displayed on display unit 310 to select the item or button may be simply expressed as "pressing (or selecting) the item or button."

[0079] (6-1. Operation monitor) FIG. 11 shows an example of the display screen when "Operation Monitor" is selected on the home screen of FIG. 6 or the like. "Operation Monitor" is an item for monitoring the operating status of the fermentation processor 100. On the display screen of "Operation Monitor", a home button H2 is displayed in the heading section H1. When the inputter presses the home button H2, the display screen of the display unit 310 returns to the home screen (see FIGS. 6, 8, and 9) according to the type of inputter, under the control of the control unit 330. Similarly, on other display screens, when the inputter presses the home button H2, the display screen of the display unit 310 returns to the home screen.

[0080] When the "Operation Monitor" option is selected via the input unit 320, the control unit 330 displays information about the operating status of the fermentation processor 100 on the display unit 310. For example, based on the detection results of the various sensors shown in FIG. 5, the display unit 310 displays the elapsed time of standard operation, the time until the start of power-saving operation, the weight of the contents (material to be processed), the current weight loss (weight of the contents reduced), the daily input weight, the outside air temperature and humidity, the current temperature and set value of the intake air, and the current temperature and set value of the tank heater. Note that power-saving operation refers to a mode in which the fermentation processor 100 operates with low power consumption and is used, for example, when quiet operation of the fermentation processor 100 is desired on holidays. In FIG. 11, "Standard Operation in Progress" is displayed, indicating that the fermentation processor 100 is currently operating in standard operation. Furthermore, the set value is a value that can only be set by the developer, and is displayed on the display unit 310 in a color (e.g., yellow) that differs from values ​​other than the set value (e.g., white). In the drawings, the numerical values ​​are indicated by being enclosed in dashed lines to indicate that they are set values.

[0081] In this embodiment, when "Operation Monitor," i.e., an item for monitoring the operating status of the fermentation processor 100, is selected by the input unit 320 from among the items selectable by the inputter, the control unit 330 causes the display unit 310 to display information indicating the operating status, grouped by parameter for monitoring the operating status. In the example of FIG. 11 , when the parameters for monitoring the operating status include the outside air temperature, the intake air temperature, and the tank heater temperature, this information is grouped by parameter and displayed on the display unit 310. Here, the grouping is performed using different colors. For example, on the display unit 310, an area presenting information regarding the outside air temperature and humidity is displayed in light blue, an area presenting information regarding the current intake air temperature and set value is displayed in orange, and an area presenting information regarding the current tank heater temperature and set value is displayed in red. In FIG. 11 , for convenience, the hatching of the areas is changed for each of the above parameters to indicate the different display colors.

[0082] In this way, the display unit 310 displays information indicating the operating status of the fermentation processor 100 in groups according to the parameters that monitor the operating status, making it easier for the person entering information to see the operating status information displayed on the display unit 310. As a result, the person entering information can intuitively and easily grasp the operating status of the fermentation processor 100.

[0083] Furthermore, under the control of the control unit 330, the display screen of the "operation monitor" also displays items that can be input by the person inputting information. For example, the display unit 310 displays buttons for instructing the fermentation processor 100 to "start operation" and "stop operation" as items that can be input by the person inputting information. That is, the control unit 330 as a display control unit causes the display unit 310 to further display, as an item that can be selected and input by the input unit 320, an item for instructing the start or stop of operation of the fermentation processor 110, in addition to information indicating the operating state such as the outside air temperature. This allows the person inputting information to operate the input unit 320 on the display device 300 side and input an instruction to start or stop operation of the fermentation processor 100.

[0084] Furthermore, on the display screen of the "operation monitor", a button for instructing "forced start of power-saving operation" and an "OFF" button for pausing the standard operation elapsed time are displayed under the control of the control unit 330. When the inputter presses "forced start of power-saving operation", a confirmation screen for switching from standard operation to power-saving operation is displayed as a pop-up on the display unit 310, as shown in FIG. 12. When the inputter selects "Yes", the operation of the fermentation processor 100 is switched from standard operation to power-saving operation under the control of the control unit 330.

[0085] Although not shown, during power-saving operation, the display unit 310 displays "Power-saving operation in progress" and also displays a button for instructing "Forced start of standard operation." When the inputter presses "Forced start of standard operation," a confirmation screen for switching from power-saving operation to standard operation pops up on the display unit 310, and when the inputter instructs the above-mentioned switching using the input unit 320, the operation of the fermentation processor 100 is switched from power-saving operation to standard operation under the control of the control unit 330.

[0086] The display unit 310 also displays an "OFF" button for so-called excess water correction, which adjusts the degree of dryness in the fermenter 1. For example, the user can determine whether or not it is necessary to perform excess water correction, which increases the degree of dryness in the fermenter 1, based on the weight of the contents and the weight loss displayed on the display unit 310. Excess water correction specifically involves correction of the temperature of the tank heater, the temperature of the intake heater BH, etc. If the user determines that excess water correction is not necessary, they can stop the execution of excess water correction by pressing the "OFF" button.

[0087] (6-2. Error display) FIG. 13 shows an example of a display screen when the "Error Display" item is selected on the home screen. When the "Error Display" item is selected on the home screen, a list of lower-level items located below "Error Display" is displayed on display unit 310 under the control of control unit 330. Here, the lower-level items are "Current" and "History." Although the lower-level items are not indicated by double borders in the figure, they are displayed on display unit 310 so as to be selectable by input unit 320.

[0088] That is, when a hierarchical item (e.g., "Error Display") is selected by the input unit 320, the control unit 330 as a display control unit causes the display unit 310 to display a list of lower-level items (e.g., "Occurring" and "History") positioned below the selected hierarchical item so that they can be selected by the input unit 320.

[0089] When the person inputting information selects "occurring" using the input unit 320, or when the "occurring" screen is set as the default screen for "error display," the current error occurrence status in the fermentation processor 100 is displayed on the left side of the screen on the display unit 310. When the person inputting information presses and selects the comment section of the displayed error occurrence status using the input unit 320, the code of the error that has occurred and detailed information about the error that has occurred are displayed on the right side of the screen, as shown in FIG.

[0090] The "Occurring" display screen also displays a buzzer stop button and a reset button. When an error occurs and the buzzer BZ (see Figure 5) sounds, the user can press the buzzer stop button to stop the buzzer BZ from sounding. After eliminating the cause of the error, the user can press the reset button, and the error status and error details will disappear from the screen.

[0091] When the user selects "History" using input unit 320 on the "Error Display" screen of FIG. 13 or 14, the history of errors that have occurred is displayed on display unit 310, as shown in FIG. 15. For example, the date and time of occurrence of errors that have occurred up to now and the error items (error code, error status) are displayed in order on display unit 310. When the cause of the error has been eliminated, the recovery date and time are also displayed on display unit 310. Furthermore, a delete button and a delete all button are also displayed on display unit 310. If the user wishes to delete part of the history, the user can select the error item to be deleted by pressing input unit 320, and then press the delete button to delete the error item from the history. Furthermore, the user can delete all error items from the history by pressing the delete all button.

[0092] In this way, on the "Error Display" screen, a list of lower-level items included in the "Error Display" ("Current" and "History") is displayed on display unit 310, so the person inputting information can easily recognize the hierarchical relationship between the upper and lower levels and the contents of the lower-level items. Also, the person inputting information can look at the list of lower-level items displayed on display unit 310, further select a desired item included in the lower-level items using input unit 320, and check the contents.

[0093] When a hierarchical item is selected by the input unit 320, a list of lower-level items is displayed, even when the hierarchical items selected are "forced drive," "extended monitor," "operating data," or "settings" (see Figures 17, 24, 28, and 30).

[0094] (6-3. Removal) 16 shows an example of the display screen when the "Remove" item is selected on the home screen. When the "Remove" item is selected on the home screen, under the control of control unit 330, a "Forward" button, a "Reverse" button, and a "Remaining position" button are displayed on display unit 310 so that they can be selected by input unit 320. All of these buttons are used to rotate agitation motor 5 (see FIG. 5) forward or backward, thereby rotating agitation claws 3 (see FIG. 2) forward or backward in the circumferential direction.

[0095] For example, if an abnormality occurs in the fermentation processor 100 and the material to be treated in the fermenter 1 needs to be removed from the inlet 4 in order to inspect the inside of the fermenter 1, the user presses the "forward" button or the "reverse" button to cause the control unit 330 to rotate the agitator motor 5 forward or reverse, and shift the agitator claws 3 to a position where they do not overlap with the inlet 4. This allows the user to remove the material to be treated in the fermenter 1 to the outside through the inlet 4. Alternatively, the user can press the "fixed position" button to cause the control unit 330 to rotate the agitator motor 5 (for example, in the forward direction), thereby rotating the agitator claws 3 to a predetermined position.

[0096] (6-4. Forced drive) 17 shows an example of a display screen when "Forced Drive" is selected on the home screen. When "Forced Drive" is selected on the home screen, a list of lower-level items below "Forced Drive" is displayed on display unit 310 under the control of control unit 330 so that the items can be selected by input unit 320. Here, the lower-level items are "Agitator Motor," "Tank Heater," "Intake Blower Heater," and "Signal Tower."

[0097] (6-4-1. "Agitator motor" screen) When the inputter selects "Agitator Motor" on the "Forced Drive" display screen using input unit 320, or when the "Agitator Motor" screen is set as the default screen for "Forced Drive," buttons for instructing forced drive of agitator motor 5 are displayed on display unit 310. In FIG. 17 , a "Forward" button for forcibly rotating agitator motor 5 forward, a "Reverse" button for forcibly rotating agitator motor 5 reversely, a "One Pitch" button for moving (rotating) agitator claw 3 one pitch, and a "Fixed Position" button for rotating agitator claw 3 to a fixed position are displayed. When the inputter presses the "Forward" button or the "Reverse" button, control unit 330 can rotate agitator motor 5 forward or reverse, thereby rotating agitator claw 3 forward or reverse. Furthermore, when the inputter presses the "Fixed Position" button, control unit 330 can rotate agitator motor 5 (for example, forward), thereby rotating agitator claw 3 to a specified position.

[0098] Furthermore, when the user presses the "1 pitch" button, the control unit 330 can rotate the agitator motor 5 for a time period corresponding to one pitch. Note that the above-mentioned one pitch corresponds to "the number of agitator claws 3 attached to the rotating shaft 2 divided by a rotation angle of 360°." When the agitator claws 3 need to be replaced due to their lifespan or other reasons, the agitator claws 3 are rotated by an angle corresponding to the number of times the "1 pitch" button is pressed, and the agitator claws 3 are moved to a predetermined position in the fermenter 1 where space for replacement work is secured. This allows the agitator claw 3 to be replaced.

[0099] Display unit 310 also displays the rotation speed and rotation speed setting value of agitator motor 5. When the inputter presses the display area for the rotation speed setting value of agitator motor 5 using input unit 320, a screen for selecting the rotation speed of agitator motor 5 pops up, as shown in Fig. 18. The inputter can set the desired agitation speed by pressing and selecting the display area for the desired agitation speed using input unit 320.

[0100] (6-4-2.
