Description
[Technical Field]
[0001] The disclosed embodiments relate to a water discharge control system. [Background technology]
[0002] In recent years, with the advancement of behavior recognition technology that recognizes the intention of a person from their behavior, progress has been made in developing systems that automatically understand a person's intention and appropriately control the faucet without the person having to operate it. For example, there is a technology that has a flushing operation mode and a water supply operation mode, and in the flushing operation mode, if the object is highly soiled, starts discharging water at high water pressure (for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent No. 6403041 Summary of the Invention [Problem to be solved by the invention]
[0004] However, the above-mentioned conventional technology has room for improvement. For example, in the above-mentioned conventional technology, when small tableware such as spoons or small plates are dirty, water is discharged at high water pressure, causing water splashing around the sink and onto ingredients being cooked, making it difficult to say that the control of water discharge and stopping is user-friendly. As such, the above-mentioned conventional technology has room for improvement, and it is desirable to implement control of water discharge and stopping that is user-friendly.
[0005] The disclosed embodiment aims to provide a water discharge control system that executes control related to stopping and discharging water in a manner that is user-friendly. [Means for solving the problem]
[0006] A water discharge control system according to one aspect of the embodiment comprises a water discharge unit, an imaging unit that images at least the water discharge area, a determination unit that determines whether an imaged object detected from the image captured by the imaging unit is an object to be discharged, and a control unit that controls the water discharge state of the water discharge unit, and is characterized in that the control unit controls the instantaneous water discharge flow rate from the water discharge unit based on at least one of the size of the object to be discharged, the type of the object to be discharged, or the distance between the water discharge outlet of the water discharge unit and the object to be discharged, as determined by the determination unit.
[0007] For example, the desired water discharge flow rate (water pressure) may vary depending on the object to be discharged and the distance from the water outlet. For example, if the water pressure is too strong, splashing may occur, while if the water pressure is too weak, sufficient cleaning may not be achieved. Therefore, according to one aspect of the water discharge control system, by controlling the instantaneous water discharge flow rate based on at least one of the size of the object to be discharged, the type of object to be discharged, or the distance between the water outlet of the water discharge unit and the object to be discharged, it is possible to set the water discharge flow rate (water pressure) appropriate for the water discharge situation, thereby preventing splashing while providing sufficient cleaning and improving usability. Therefore, the water discharge control system can execute control related to stopping and discharging water in a way that is user-friendly.
[0008] In one aspect of the embodiment, in the water discharge control system, the control unit increases the instantaneous water discharge flow rate as the object to be discharged with water becomes larger.
[0009] For example, it is assumed that there is a correlation between the size of the object to be discharged and the water discharge flow rate that the user perceives as optimal. Therefore, according to one aspect of the embodiment, the water discharge control system can improve usability by controlling the water discharge flow rate according to the size of the object to be discharged. Therefore, the water discharge control system can execute control related to stopping and discharging water in a way that is user-friendly.
[0010] In one aspect of the embodiment, in the water discharge control system, the control unit classifies the object onto which water is to be discharged as either an item or a person's hand, and controls the instantaneous water discharge flow rate based on the classification result.
[0011] According to the water discharge control system of one aspect of the embodiment, by distinguishing between the type of object to be discharged, such as supplies (items, foodstuffs, etc.) or a person's hand, and controlling the water discharge flow rate, it is possible to control the water discharge flow rate to an appropriate level for each object, thereby improving usability. Therefore, the water discharge control system can execute control related to stopping and discharging water in a way that is user-friendly.
[0012] In one aspect of the embodiment, in the water discharge control system, if the object to be discharged is the equipment, the control unit further classifies the object to be discharged as either an article or a food ingredient, and controls the instantaneous water discharge flow rate based on the classification result.
[0013] According to one aspect of the embodiment, the water discharge control system controls the water discharge flow rate by distinguishing whether the item is an article or food material, thereby enabling the water discharge flow rate to be controlled to an appropriate level for each object, thereby improving usability. Therefore, the water discharge control system can execute control related to water discharge stop that is user-friendly.
[0014] In one aspect of the embodiment, the control unit of the water discharge control system determines the distance between the water discharge outlet and the object to which water is discharged based on the image, and controls the magnitude of the instantaneous water discharge flow rate according to changes in the distance.
[0015] According to the water discharge control system of one aspect of the embodiment, by making it possible to control the water discharge flow rate according to the distance from the water discharge port, even for the same water discharge target, the user can adjust the water discharge flow rate according to their preference, for example, prioritizing water conservation or workability, thereby improving usability. Therefore, the water discharge control system can execute control related to water discharge and stopping that is user-friendly.
[0016] In the water discharge control system according to one aspect of the embodiment, the control unit determines that one of the imaged objects having a predetermined moving speed is the water discharge target object.
[0017] For example, there may be cases where water should not be discharged onto an object that is simply placed in the sink. Therefore, according to the water discharge control system of one aspect of the embodiment, an object that is determined to be in use is determined to be a water discharge target and water is discharged onto that object, thereby improving usability. Therefore, the water discharge control system can execute control related to stopping and discharging water in a manner that is user-friendly.
[0018] In the water discharge control system according to one aspect of the embodiment, the control unit determines that the object to be imaged that is within a first area is the water discharge target object.
[0019] For example, there may be cases where water should not be discharged onto an object that is simply placed in the sink. Therefore, according to the water discharge control system of one aspect of the embodiment, an object that is determined to be in use is determined to be a water discharge target and water is discharged onto that object, thereby improving usability. Therefore, the water discharge control system can execute control related to stopping and discharging water in a manner that is user-friendly.
[0020] In one aspect of the embodiment, in the water discharge control system, when the shape of the object to be discharged is a predetermined type, the control unit controls the instantaneous water discharge flow rate based on the predetermined type.
[0021] According to one aspect of the embodiment, the water discharge control system controls the instantaneous water discharge flow rate according to the shape of the object to be discharged, thereby enabling water discharge control that takes into account the tendency of water to splash depending on the shape of the object to be discharged, thereby improving usability. For example, the water discharge control system can reduce water splashing by reducing the flow rate for objects with curved shapes, such as spoons and ladles. Furthermore, for example, the water discharge control system can reduce water splashing and improve usability by controlling the water discharge flow rate according to the shape of the object, such as the angle of the object, the presence or absence of protrusions, and the front and back. Therefore, the water discharge control system can execute control related to stopping and discharging water in a way that is user-friendly.
[0022] In one aspect of the embodiment, in a water discharge control system, the control unit does not change the instantaneous water discharge flow rate when the size of the object to be discharged changes while it is retained within the water discharge area.
[0023] For example, there may be cases where water should not be discharged onto an object simply placed in the sink. Therefore, the water discharge control system according to one aspect of the embodiment does not perform follow-up water pressure control, thereby reducing the control load and alleviating discomfort experienced by the user. For example, even if the water discharge control system performs control with a slight delay in response to changes in the position of the object to be discharged, it can alleviate discomfort experienced by the user. Therefore, the water discharge control system can execute control related to stopping and discharging water in a manner that is user-friendly.
[0024] A water discharge control system according to one aspect of the embodiment includes an acquisition means for acquiring the water discharge pattern from the water discharge unit, and the control unit controls the instantaneous water discharge flow rate according to the water discharge pattern acquired by the acquisition means.
[0025] For example, compared to straight water spouting, shower water spouting can have a different optimal water pressure due to factors such as increased water velocity. Therefore, according to one aspect of the embodiment, the water spouting control system can improve usability by controlling the water spout flow rate according to the water spouting pattern. Therefore, the water spouting control system can execute control related to water spouting and stopping that is user-friendly.
[0026] In one aspect of the embodiment, in a water discharge control system, the control unit increases the instantaneous water discharge flow rate as the size of the object to be discharged increases, and changes the control of the instantaneous water discharge flow rate depending on the type of object to be discharged.
[0027] For example, it is conceivable that, for tools, the larger the object, the greater the water discharge flow rate, but for a human hand, compared to tools, a smaller change in water discharge flow rate relative to the size of the object is more appropriate. Therefore, according to one aspect of the embodiment, the water discharge control system can improve usability by controlling the water discharge flow rate according to the size and type of the object to be discharged. Therefore, the water discharge control system can execute control related to stopping and discharging water in a way that is user-friendly.
[0028] In one aspect of the embodiment, in a water discharge control system, the control unit increases the instantaneous water discharge flow rate the larger the size of the object to be discharged, and when the object to be discharged is a human hand, the amount of change in the instantaneous water discharge flow rate is reduced compared to when the object is an item.
[0029] For example, it is conceivable that, for tools, the larger the object, the greater the water discharge flow rate, but for a human hand, compared to tools, a smaller change in water discharge flow rate relative to the size of the object is more appropriate. Therefore, according to one aspect of the embodiment, the water discharge control system can improve usability by controlling the water discharge flow rate according to the size and type of the object to be discharged. Therefore, the water discharge control system can execute control related to stopping and discharging water in a way that is user-friendly.
[0030] In one aspect of the embodiment, in the water discharge control system, the control unit reduces the amount of change in the instantaneous water discharge flow rate based on changes in the size of the object to which water is discharged, the larger the size of the object to which water is discharged.
[0031] For example, it is possible to assume that the optimal amount of change in the instantaneous water discharge rate varies depending on the object to be discharged. Therefore, according to one aspect of the embodiment, the water discharge control system can improve usability by reducing the amount of change in the instantaneous water discharge rate based on changes in the size of the object to be discharged, as the size of the object to be discharged increases. Therefore, the water discharge control system can execute control related to stopping and discharging water in a way that is user-friendly.
[0032] In one aspect of the embodiment, in the water discharge control system, when the water discharge mode is shower discharge, the control unit reduces the amount of change in the instantaneous water discharge flow rate based on a change in the size of the object to which water is discharged.
[0033] For example, it is possible to assume that the amount of change in the optimal instantaneous water discharge rate will differ depending on the water discharge mode. Therefore, according to a water discharge control system according to one aspect of the embodiment, when the water discharge mode is shower water discharge, the amount of change in the instantaneous water discharge rate based on changes in the size of the object to be discharged can be reduced, thereby improving usability. Therefore, the water discharge control system can execute control related to stopping and discharging water in a way that is user-friendly.
[0034] A water discharge control system according to one aspect of the embodiment includes a water discharge temperature adjustment unit that adjusts the temperature of water discharged from the water discharge unit, and the water discharge temperature adjustment unit detects the degree of dirtiness of the object onto which water is discharged and increases the water discharge temperature.
[0035] For example, there is a possibility that a sufficient amount of water may not be discharged to a soiled object based solely on the size, type, distance, etc. of the object to be discharged. Therefore, according to a water discharge control system according to one aspect of the embodiment, by controlling the temperature according to the degree of soiling, it is possible to compensate for the cleaning power by the temperature, thereby improving usability. Therefore, the water discharge control system can execute control related to stopping and discharging water in a manner that is user-friendly. [Effects of the Invention]

[0038] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the water discharge control system disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments.
[0039] <1. First embodiment> First, a water discharge control system 1 according to a first embodiment will be described below. To control water discharge and stopping (also referred to as "water discharge stopping"), the water discharge control system 1 detects an object (also referred to as "imaged object") based on information detected by a sensor or the like that captures an image, and controls water discharge stopping depending on whether the detected object (imaged object) is an object for which water discharge control is to be performed (also referred to as "water discharge target object"). For example, the object may be kitchen-related objects such as ingredients, tableware, and cooking utensils (hereinafter also referred to as "supplies"), a part of the human body such as the body, head, or hand of a person (also referred to as "user"), or kitchen elements such as a stove, sink, or water discharge unit. Furthermore, the water discharge target object includes at least one of a person's (user's) hand and an item. Note that the processes described for the water discharge control system according to each embodiment, such as the water discharge control system 1, may be performed by any device capable of performing the processes, depending on the device configuration included in the water discharge control system.
[0040] <1-1. Water discharge control system configuration> The configuration of a water discharge control system 1 according to a first embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a schematic perspective view of the water discharge control system according to the first embodiment. Fig. 2 is a diagram showing an example of the configuration of the water discharge control system according to the first embodiment.
[0041] As shown in Figures 1 and 2, the water discharge control system 1 has a kitchen main body 2, an imaging unit 10, a control unit 100, a water valve 101, a purified water valve 102, a hot water valve 103, and a flow rate adjustment valve 104. The kitchen main body 2 is a plumbing equipment main body. The kitchen main body 2 has a water discharge unit 30, a sink 40, and a stove unit 50 on an upper surface unit 20 where a user performs tasks such as cooking and washing dishes and other objects. For example, the kitchen main body 2 may be a system kitchen.
[0042] The water discharge control system 1 may also include a water supply 80 and a water heater 81. The water supply 80 and the water heater 81 are components for supplying water to be discharged from the water discharge unit 30 via a water valve 101, a purified water valve 102, a hot water valve 103, a flow rate adjustment valve 104, and the like. For example, the water supply 80 is a water supply tool connected to a water distribution pipe or the like, and is connected to the water valve 101, the purified water valve 102, and the water heater 81. The water heater 81 is a device for heating water supplied from the water supply 80 to hot water, and is connected to the hot water valve 103. For example, the hot water temperature of the water heater 81 may be controlled by the control unit 100. In this case, the water heater 81 supplies hot water to the water discharge unit 30 via the hot water valve 103 at a temperature according to the control of the control unit 100. Note that the configuration shown in FIG. 2 is merely an example, and any configuration may be adopted as long as it is possible to discharge water in a desired manner.
[0043] 1 and 2 is merely an example, and any configuration can be adopted for the kitchen body 2. For example, the kitchen body 2 does not have to include the stove unit 50. In this case, the stove unit 50 may be provided separately from the kitchen body 2.
[0044] 1, a wall cabinet 60 and a range hood 70 are provided above the kitchen body 2, that is, on the side facing the upper surface 20 of the kitchen body 2. The wall cabinet 60 and the range hood 70 do not necessarily have to be provided.
[0045] The upper surface 20 of the kitchen main body 2 is used for user work. For example, the surface of the upper surface 20 of the kitchen main body 2 between the sink 40 and the stove unit 50 functions as a work surface where the user can perform processing such as cutting ingredients or place dishes after washing. Furthermore, multiple work surfaces may be arranged, such as between the sink 40 and the stove unit 50 and on the right side of the sink 40.
[0046] Water discharger 30 has a water discharge port 321 provided in head 32, which is the tip end portion of water discharge pipe 31, and discharges (spouts) water from water discharge port 321. For example, water discharger 30 may be able to discharge water in any water discharge form (shower, straight, etc.) from water discharge port 321. In this case, water discharger 30 may be able to switch between straight water and shower water from water discharge port 321. For example, water discharger 30 may discharge water in a water discharge form selected by the user, or may discharge water in a water discharge form corresponding to a mode described below.
[0047] 1 and 2, the water discharge unit 30 can switch between discharging a plurality of types of water, such as raw water, purified water, and hot water (also referred to as "hot water" or "warm water"), in accordance with the control of the control unit 100 on the water valve 101, the purified water valve 102, and the hot water valve 103. The water discharge unit 30 can also change the discharge flow rate (also referred to simply as "flow rate"), such as the instantaneous discharge flow rate, of any type of water, such as raw water, purified water, or hot water (warm water), in accordance with the control of the flow rate adjustment valve 104 by the control unit 100. The water discharge unit 30 may be configured to discharge only raw water. In this case, the water discharge control system 1 has only the water valve 101 among the water valve 101, the purified water valve 102, and the hot water valve 103. The water discharge unit 30 refers to, for example, the part exposed from the kitchen main body 2.
[0048] Sink 40 is a recess recessed from the surface of upper surface 20, and functions as a water receiving portion that receives water from water discharger 30. Sink 40 is used, for example, for washing objects such as dishes, and is a tank-like stand equipped with a drainage groove that drains water from water discharger 30, etc.
[0049] The stove unit 50 is a stove equipment used by a user for heating operations for cooking. While FIGS. 1 and 2 show an example in which the stove unit 50 has two heating units, 51 and 52, the stove unit 50 may have one heating unit or three or more heating units. The heating units 51 and 52 perform heating using any heat source, such as gas or electricity. In this way, the heating units 51 and 52 can be configured as any type, such as an electric stove, an induction stove, or a gas stove.
[0050] The control unit 100 is a control device that performs control related to water discharge. The control unit 100 performs control related to water discharge by controlling the cold water valve 101, the purified water valve 102, the hot water valve 103, and the flow rate adjustment valve 104 based on information (sensor information) detected by each sensor such as the imaging unit 10. The control unit 100 detects an object to be discharged from an image captured by the imaging unit 10, and controls the water discharge unit 30 based on the detection result. Note that the processing using the image captured by the imaging unit 10 is one example, and the control unit 100 may perform control related to water discharge using sensor information detected by any sensor, not limited to the imaging unit 10.
[0051] For example, the control unit 100 controls the type of water discharge by controlling the switching of the cold water valve 101, the purified water valve 102, and the hot water valve 103 based on information detected by each sensor such as the imaging unit 10. For example, the control unit 100 controls the water discharge flow rate, such as the instantaneous water discharge flow rate, by controlling the flow rate adjustment valve 104 based on information detected by each sensor such as the imaging unit 10.
[0052] Furthermore, the control settings of the control unit 100 for the cold water valve 101, the purified water valve 102, the hot water valve 103, and the flow rate adjustment valve 104 may be changed by the user to their preferred settings. For example, the control settings may be changed by the user to reduce the flow rate of purified water discharged to food ingredients, or to change the water discharged to cold water for stains. When detecting an object to be discharged from an image, the control unit 100 performs any processing on the captured image, such as brightness and color correction (image correction), monochrome / color conversion (image conversion), object identification (image recognition), and area measurement (image feature extraction).
[0053] The water valve 101 is, for example, a solenoid valve, and functions as a valve for discharging raw water to the water discharge portion 30. The purified water valve 102 is, for example, a solenoid valve, and functions as a valve for discharging purified water to the water discharge portion 30. The hot water valve 103 is, for example, a solenoid valve, and functions as a valve for discharging hot water (warm water) to the water discharge portion 30. The control unit 100 is connected to each of the water valve 101, the purified water valve 102, and the hot water valve 103. Note that instead of the water valve 101, the purified water valve 102, and the hot water valve 103, a single flow path switching valve may be used to switch between each type of water discharge (raw water, purified water, hot water, etc.).
[0054] For example, the control unit 100 is connected to a water valve 101 that switches between discharging and stopping the raw water by the water discharge unit 30. The control unit 100 controls the discharge and stopping of raw water by the water discharge unit 30 using a control signal that opens and closes the water valve 101.
[0055] For example, the control unit 100 is connected to a purified water valve 102 that switches between discharging and stopping purified water by the water discharge unit 30. The control unit 100 controls the discharging and stopping of purified water by the water discharge unit 30 using a control signal that opens and closes the purified water valve 102.
[0056] For example, the control unit 100 is connected to a hot water valve 103 that switches between discharging and stopping hot water from the water discharge unit 30. The control unit 100 controls the discharging and stopping of hot water from the water discharge unit 30 by a control signal that opens and closes the hot water valve 103.
[0057] Flow rate adjustment valve 104 is, for example, a control valve that can continuously change the valve opening, and functions as a valve for adjusting the flow rate of water discharged from water discharger 30. For example, flow rate adjustment valve 104 supplies the type of water selected by controlling cold water valve 101, purified water valve 102, and hot water valve 103 to water discharger 30 at a valve opening controlled by control unit 100. Note that any valve configuration may be used for flow rate adjustment valve 104 as long as it can be adjusted to any valve opening (position), such as 0 to 100%.
[0058] For example, the control unit 100 is connected to a flow rate adjustment valve 104 that adjusts the water discharge flow rate, such as the instantaneous water discharge flow rate, of the water discharge unit 30. The control unit 100 controls the water discharge flow rate, such as the instantaneous water discharge flow rate, of the water discharge unit 30 using a control signal that adjusts (specifies) the valve opening degree of the flow rate adjustment valve 104.
[0059] Furthermore, the control unit 100 is communicably connected to each sensor, such as the imaging unit 10, via a predetermined network, such as the Internet, either wired or wirelessly. For example, the control unit 100 has a communication function (communication unit) for transmitting and receiving information to and from other devices. The communication function (communication unit) of the control unit 100 is realized by a communication device, a communication circuit, or the like. The control unit 100 is connected to an arbitrary network via wired or wirelessly using the communication function, and transmits and receives information to and from an external information processing device. For example, the control unit 100 transmits and receives information to and from the imaging unit 10, etc. Note that the control unit 100 may be connected to each sensor in any manner as long as it is possible to transmit and receive information, and may be communicably connected via wired or wireless.
[0060] The control unit 100 may be disposed in any location. The control unit 100 may be provided inside the space corresponding to the kitchen main body 2 (kitchen room), or may be provided outside the space corresponding to the kitchen main body 2 (kitchen room).
[0061] The control unit 100 may be configured and arranged in any manner as long as it can control the switching of the cold water valve 101, the purified water valve 102, and the hot water valve 103, adjust the valve opening of the flow rate adjustment valve 104, and communicate with and process sensors such as the imaging unit 10. The control unit 100 may also be arranged inside the kitchen main body 2. The control unit 100 may also be arranged outside the kitchen main body 2, rather than inside it. Details of the control unit 100 will be described later.
[0062] The imaging unit 10 captures an image of the bathroom space, etc. The imaging unit 10 captures an image of at least the water discharge area. The imaging unit 10 functions as a sensor unit that acquires information used to control water discharge. For example, the imaging unit 10 is a camera module that acquires an image by capturing an image of a predetermined area, such as the inside of the sink 40, or a sensor unit that uses an image sensor. The imaging unit 10 captures an image of the bathroom space around the water discharge unit 30. For example, the imaging unit 10 captures an image of the bathroom space including the sink 40, etc.
[0063] The imaging unit 10 is disposed in a position where it can capture an image of a desired range (area). For example, the imaging unit 10 is provided on the upper part (upper side) of the kitchen main body 2. The imaging unit 10 is provided in a position facing the kitchen main body 2 from above the kitchen main body 2. FIGS. 1 and 2 show, as an example, a case where the imaging unit 10 is disposed on the underside of a wall cabinet 60 provided above the kitchen main body 2. Note that the placement of the imaging unit 10 shown in FIGS. 1 and 2 is merely an example, and the imaging unit 10 may be disposed in any position as long as it can capture an image of a desired range.
[0064] The imaging unit 10 uses any sensor such as a CCD (Charge Coupled Device) sensor or a CMOS (Complementary Metal Oxide Semiconductor) sensor. For example, the imaging unit 10 is an area sensor or a distance measuring sensor that uses an image sensor. The imaging unit 10 captures an image of the water-related space around the water discharger 30.
[0065] Also, for example, the imaging unit 10 is disposed facing in a direction to capture an image of the sink 40. Note that the imaging unit 10 may be disposed in any manner as long as it can detect (capture) an object. Also, the imaging unit 10 may capture a still image or a moving image.
[0066] The imaging unit 10 is connected to the control unit 100 via a predetermined network so as to be able to communicate with each other via a wired or wireless connection. The imaging unit 10 transmits various types of information to the control unit 100. For example, the imaging unit 10 transmits information related to an acquired image to the control unit 100. For example, the imaging unit 10 may be connected to the control unit 100 so as to be able to communicate with each other via a predetermined wireless communication function such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). Note that the control unit 100 and the imaging unit 10 may be connected in any manner as long as they are able to send and receive information, and may be connected to each other via a wired or wireless connection so as to be able to communicate with each other. For example, the imaging unit 10 may be connected to the control unit 100 so as to be able to communicate with each other via a wired or wireless connection.
[0067] When describing various sensors such as the imaging unit 10 without distinction, they may be referred to as "sensors." When describing information acquired by various sensors such as the imaging unit 10 without distinction, they may be referred to as "sensor information." Sensor information is a concept that includes information acquired by various sensors for water discharge control, such as information acquired by the imaging unit 10.
[0068] 1 and 2 are merely examples, and the water discharge control system 1 can have any device configuration. For example, in FIG. 2, the solid line connections between each component indicate the communication (transmission and reception) and control relationships of signals (information) between the components, and the dotted line connections between each component indicate an example of the relationship of water flow, but the relationships are not limited to those shown in FIG. 2, and any relationship can be adopted. For example, in the water discharge control system 1, the control unit 100 may communicate with the water heater 81 and control the water heater 81. Also, for example, the water discharge control system 1 may not include a sensor. In this case, the control unit 100 of the water discharge control system 1 may communicate with a sensor not included in the water discharge control system 1 and control the water discharge using sensor information received (acquired) from the sensor. For example, the water discharge control system 1 may not include the imaging unit 10. In this case, the control unit 100 of the water discharge control system 1 may communicate with an imaging unit 10 that is not included in the water discharge control system 1, and use the image received (acquired) from the imaging unit 10 to control the water discharge.
[0069] Furthermore, the water discharge control system 1 may have a personal identification unit (identification device) that performs processing (personal identification) to identify the user who uses the kitchen main body 2. For example, the control unit 100 may function as the personal identification unit. For example, the personal identification unit of the water discharge control system 1 may perform personal identification based on an image of a person included in an image. Note that the above is merely an example, and the water discharge control system 1 may perform personal identification by any method as long as it is possible to identify the user who uses the kitchen main body 2. For example, the personal identification unit of the water discharge control system 1 may acquire information for identifying the user who uses the kitchen main body 2 by communicating with a device such as a smartphone owned by the user, or by the user's operation on a remote control, and then perform personal identification of the user.
[0070] Furthermore, the water discharge control system 1 may also include sensors other than the imaging unit 10. For example, the water discharge control system 1 may also include a human body detection sensor. The human body detection sensor has the function of detecting a human body. For example, the human body detection sensor is realized by a pyroelectric sensor using an infrared signal. For example, the human body detection sensor may be realized by a μ (microwave) wave sensor. Note that the above is just an example, and the human body detection sensor is not limited to the above, and may detect a human body by various means. For example, the human body detection sensor detects a person (such as a user) who enters the space (kitchen room) in which the kitchen main body 2 is provided. The human body detection sensor transmits a detection signal to the control unit 100.
[0071] <1-2. Configuration of the control unit (control device)> Next, each component of the control unit 100 will be described in detail. The control unit 100 may be, for example, an information processing device (computer) used to control various components and processes. The control unit 100 may have, for example, a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), and may be realized by executing a program stored inside the control unit 100 (for example, an information processing program according to the present disclosure) using a RAM or the like as a working area. The control unit 100 may also have, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).
[0072] As shown in FIG. 2, control unit 100 has a switching adjustment unit 110, a processing unit 120, a storage unit 130, and an acquisition unit 140, and realizes or executes the information processing functions and actions described below. Note that the internal configuration of control unit 100 is not limited to the configuration shown in FIG. 2 and may be other configurations that perform the information processing described below. For example, processing unit 120 may be divided into a determination unit that performs processing related to determination, an operation detection unit that detects user operations, and a water discharge / stop control unit that performs processing related to controlling the water discharge / stop of water discharge unit 30. Furthermore, the processing performed by control unit 100 may be executed by a cloud server (also referred to as the cloud). In this case, the cloud and control unit 100 are connected via a predetermined network, either wired or wirelessly.
[0073] The switching adjustment unit 110 changes the water discharge mode, such as stopping or discharging water, of the water discharge unit 30. The water discharge mode refers to one mode of water discharge, such as the type of water discharge (raw water, purified water, hot water, etc.), the water discharge form (shower, straight, etc.), and the water discharge flow rate (instantaneous water discharge flow rate, etc.). The above is merely an example, and the water discharge mode may be classified in any way. For example, if purified water can be discharged as hot water, the type of water discharge may be classified as raw water, purified water at room temperature, hot water, purified water at high temperature, etc.
[0074] The switching adjustment unit 110 switches the opening and closing of the water valve 101, the purified water valve 102, and the hot water valve 103 in response to instructions from the processing unit 120. The switching adjustment unit 110 sends control signals to the water valve 101, the purified water valve 102, and the hot water valve 103, and switches the opening and closing of the water valve 101, the purified water valve 102, and the hot water valve 103, thereby switching the type of water discharged from the water discharge unit 30.
[0075] Switching adjustment unit 110 adjusts the valve opening of flow rate adjustment valve 104 in response to instructions from processing unit 120. Switching adjustment unit 110 sends a control signal to flow rate adjustment valve 104 and adjusts (sets) the valve opening of flow rate adjustment valve 104, thereby adjusting the water discharge flow rate, such as the instantaneous water discharge flow rate, of water discharge unit 30.
[0076] The processing unit 120 executes various processes related to water discharge control. The processing unit 120 functions as a determination unit that makes various determinations. For example, the processing unit 120 determines the state of an object detected from an image captured by the imaging unit 10. The processing unit 120 functions as an operation detection unit that detects an operation by the user.
[0077] The processing unit 120 functions as a detection unit that detects the object of water discharge using sensor information. The processing unit 120 detects the object of water discharge contained in the image captured by the imaging unit 10. The processing unit 120 determines whether or not the object has been detected. When detecting the object of water discharge contained in the image, the processing unit 120 performs any processing on the captured image, such as brightness and color correction (image correction), monochrome / color conversion (image conversion), object identification (image recognition), and area measurement (image feature extraction).
[0078] The processing unit 120 detects objects included in the image and their positions (coordinates, etc.) through image processing. The processing unit 120 may detect the objects included in the image and their positions (ranges) through any processing as long as it is possible to acquire information indicating the objects included in the image and their positions. This point will be described in detail later.
[0079] The processing unit 120 calculates (estimates) the moving speed of the object based on the image captured by the imaging unit 10. For example, the processing unit 120 estimates the moving speed of the object based on a change in the position (coordinates, etc.) of the object in a video. For example, the processing unit 120 estimates the moving speed of the object based on, for example, the frame rate of the video (i.e., time information) and a change in the position of the object in the video (i.e., information on the moving distance). For example, the processing unit 120 estimates the moving speed of the object by, for example, dividing the moving distance of the object in the video by the time corresponding to the frame rate of the video. Note that the above-described processing is merely an example, and the processing unit 120 may estimate the moving speed of the object using various information as appropriate.
[0080] The processing unit 120 may use the sensor information to determine whether to discharge water, and if so, select the type of water to be discharged—raw water, purified water, or hot water—based on the content stored in the memory unit 130. In this case, the processing unit 120 determines to open the valve corresponding to the selected type of water from among the cold water valve 101, the purified water valve 102, and the hot water valve 103. The processing unit 120 generates a control signal instructing the determined valve to be opened. Using the generated control signal, the processing unit 120 instructs the switching adjustment unit 110 to switch the cold water valve 101, the purified water valve 102, and the hot water valve 103 between open and closed states.
[0081] Furthermore, when discharging water, the processing unit 120 may determine the instantaneous water discharge flow rate based on the contents stored in the memory unit 130. In this case, the processing unit 120 determines the valve opening degree of the flow rate adjustment valve 104 based on the determined instantaneous water discharge flow rate. The processing unit 120 generates a control signal instructing opening at the determined valve opening degree. The processing unit 120 uses the generated control signal to instruct the switching adjustment unit 110 to adjust (set) the valve opening degree of the flow rate adjustment valve 104.
[0082] The processing unit 120 determines the object onto which water is to be discharged from the image captured by the imaging unit 10. The processing unit 120 can determine the user's hands and items from the image captured by the imaging unit 10. The processing unit 120 can determine the hands and items from the image captured by the imaging unit 10.
[0083] The processing unit 120 functions as a water discharge control unit that controls the water discharge mode from the water discharger 30. The processing unit 120 controls the switching adjustment unit 110. The processing unit 120 controls the stopping and starting of water discharge from the water discharger 30 by controlling the switching of the switching adjustment unit 110. The processing unit 120 controls the stopping and starting of water discharge from the water discharger 30 by controlling the switching adjustment unit 110 based on the judgment result.
[0084] Processing unit 120 determines the size of the object to be discharged. Processing unit 120 controls the instantaneous water discharge flow rate from water discharge unit 30 based on at least one of the size of the object to be discharged determined by the determination unit, the type of object to be discharged, or the distance between water discharge port 321 of water discharge unit 30 and the object to be discharged. Processing unit 120 increases the instantaneous water discharge flow rate as the object to be discharged is larger.
[0085] The processing unit 120 classifies the object to be discharged as either a tool or a human hand, and controls the instantaneous water discharge flow rate based on the classification result. If the object to be discharged as a tool, the processing unit 120 further classifies the object to be discharged as either an article or a food ingredient, and controls the instantaneous water discharge flow rate based on the classification result.
[0086] The processing unit 120 determines the distance between the water discharge port 321 and the object to be discharged based on the image, and controls the instantaneous water discharge flow rate according to changes in the distance. The processing unit 120 determines that an object to be imaged that has a predetermined moving speed is an object to be discharged. The processing unit 120 determines that an object to be imaged that has a moving speed that meets a predetermined standard is an object to be discharged.
[0087] For example, the processing unit 120 determines that an imaged object whose estimated moving speed is within a predetermined range is a target object for water discharge. For example, if the moving speed of the imaged object is less than a first threshold value and greater than or equal to a second threshold value, the processing unit 120 determines that the imaged object is a target object for water discharge. For example, the second threshold value is a predetermined value greater than the first threshold value. For example, if the moving speed of the imaged object is within the range between the first threshold value and the second threshold value, the processing unit 120 estimates that the imaged object is an object for which the user wants water discharged, and determines that the imaged object is a target object for water discharge.
[0088] For example, the processing unit 120 determines that an imaged object whose moving speed is less than the first threshold is not a water-discharge target. For example, the processing unit 120 estimates that an imaged object whose moving speed is less than the first threshold is an object placed there, and determines that it is not a water-discharge target.
[0089] For example, the processing unit 120 determines that an imaged object whose moving speed is equal to or greater than the second threshold is not a water-discharge target. For example, the processing unit 120 estimates that an imaged object whose moving speed is equal to or greater than the second threshold is an object moving through the image capture area, and determines that the object is not a water-discharge target.
[0090] The processing unit 120 determines that, among the objects to be imaged, those that are within the first region are objects to be water-discharged. For example, the processing unit 120 determines that, among the objects to be imaged, those that are within the first region, which is a predetermined range including the water-discharge region WA1, are objects to be water-discharged. The first region can be set to any range as long as it is possible to determine the object to be water-discharged. For example, the first region may be an area that includes a position (water-discharged drop position) where water discharged (discharged) from the water discharge port 321 falls, such as a position directly below the water discharge port 321. For example, the processing unit 120 detects objects in the first region and controls water discharge.
[0091] When the shape of the object to be discharged is a predetermined type, the processing unit 120 controls the instantaneous water discharge flow rate based on the predetermined type. When the size of the object to be discharged changes while it is held within the water discharge area, the processing unit 120 does not change the instantaneous water discharge flow rate.
[0092] Processing unit 120 controls the instantaneous water discharge flow rate according to the water discharge form acquired by acquisition unit 140. Processing unit 120 increases the instantaneous water discharge flow rate the larger the size of the object to be discharged, and changes the control of the instantaneous water discharge flow rate depending on the type of object to be discharged. Processing unit 120 increases the instantaneous water discharge flow rate the larger the size of the object to be discharged, and reduces the amount of change in the instantaneous water discharge flow rate when the object to be discharged is a human hand compared to when the object is an item.
[0093] The larger the size of the object onto which water is to be discharged, the smaller the amount of change in the instantaneous water discharge flow rate based on a change in the size of the object onto which water is to be discharged. When the water discharge mode is shower water discharge, the processing unit 120 reduces the amount of change in the instantaneous water discharge flow rate based on a change in the size of the object onto which water is to be discharged.
[0094] Processing unit 120 may function as a discharged water temperature adjustment unit that adjusts the temperature of water discharged from water discharge unit 30. For example, processing unit 120 controls water heater 81 to adjust the temperature of hot water supplied from water heater 81 to water discharge unit 30 via hot water valve 103. Processing unit 120 detects the degree of dirtiness of the object onto which water is to be discharged and increases the temperature of the discharged water.
[0095] The processing unit 120 detects user operations using sensor information. The processing unit 120 detects user operations related to controlling the water discharge state. For example, the processing unit 120 detects operations related to changing modes. For example, the processing unit 120 detects a mode switching operation by the user. For example, the processing unit 120 detects user operations based on user gestures detected from an image captured by the imaging unit 10. For example, the processing unit 120 detects user operations based on the user's hand movements (hand signs, etc.) detected from an image captured by the imaging unit 10.
[0096] Note that the above is merely an example, and the processing unit 120 may detect the user's operation using various information. For example, if an operation device such as an operation panel is provided in the kitchen main body 2, the processing unit 120 may detect the user's operation using operation information indicating the user's operation on the operation device.
[0097] The storage unit 130 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. For example, the storage unit 130 is a computer-readable recording medium that non-temporarily records data used by an information processing program. The storage unit 130 stores various information such as information detected by various sensors. The storage unit 130 stores various information used to control water discharge.
[0098] The memory unit 130 stores various information used to detect an object to be discharged with water. For example, the memory unit 130 stores a program that detects an object to be discharged with water, determines whether to discharge water or stop water, and so on. For example, the memory unit 130 stores a threshold value used in a determination process related to the control of water discharge and stop. For example, the memory unit 130 stores a threshold value used in a determination process of whether an object to be discharged with water has been detected. The above is merely an example, and the memory unit 130 stores various information related to the process.
[0099] The storage unit 130 may store various types of information depending on the purpose, without being limited to the above. The storage unit 130 may store sensor information detected by various sensors. The storage unit 130 may store the sensor information in association with the date and time when it was acquired. The storage unit 130 may store an image as sensor information. The storage unit 130 stores information indicating the processing result corresponding to the image in association with the image. The storage unit 130 stores the determination result determined for the image (presence or absence of an object to be discharged water, etc.) in association with the image.
[0100] The acquisition unit 140 acquires information. The acquisition unit 140 acquires various information from the storage unit 130. The acquisition unit 140 acquires various information from the kitchen main body 2. The acquisition unit 140 acquires various information collected in a space (kitchen room) corresponding to the kitchen main body 2 from the kitchen main body 2. The acquisition unit 140 acquires user identification information that identifies a user from the kitchen main body 2.
[0101] The acquisition unit 140 acquires sensor information detected by the sensor from the sensor. The acquisition unit 140 acquires sensor information of the user sensed by the sensor. The acquisition unit 140 receives information related to the image acquired by the imaging unit 10 from the imaging unit 10. The acquisition unit 140 may store the received various information in the storage unit 130.
[0102] The acquisition unit 140 acquires the water discharge mode from the water discharger 30. The acquisition unit 140 acquires information indicating whether the water discharge mode of the water discharger 30 is straight or shower. The acquisition unit 140 acquires information indicating the water discharge mode of the water discharger 30 from the water discharger 30. The acquisition unit 140 receives a signal (information) indicating the water discharge mode from the water discharger 30.
[0103] The above-described configuration of the control unit 100 is merely an example, and the control unit 100 may have various configurations other than the above. For example, if the control unit 100 has a function of displaying information, it may have a display unit.
[0104] <1-3. Area example> Before describing the specific processing according to the first embodiment, an example of a water discharge area will be described using Fig. 3. Fig. 3 is a diagram showing an example of the area. Fig. 3 shows a case corresponding to a plan view (hereinafter simply referred to as "plan view") of the upper surface portion 20 from above the kitchen body 2. For example, Fig. 3 shows an example of a water discharge area WA1.
[0105] In Fig. 3, the water discharge area WA1 includes an area that overlaps with the water discharge outlet (e.g., water discharge outlet 321) that discharges water from the water discharger 30 in a plan view. Note that the water discharge area WA1 shown in Fig. 3 is only an example, and the water discharge area can be changed to any range. For example, the water discharge area WA1 can be set to any range as long as it includes an area that overlaps with the water discharge outlet in a plan view.
[0106] <1-4. Example of processing using images> Here, an example of a process using an image executed by the water discharge control system will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of a process using an image executed by the water discharge control system.
[0107] Image IM1 in FIG. 4 shows an example of a case where an image captured by the imaging unit 10 is the processing target. In FIG. 4, the water discharge control system 1 shows an example of a processing result when the processing target is image IM1 that includes a person's hand and utensils (tableware). For example, the water discharge control system 1 uses any image recognition technology to detect the area in image IM1 where the captured object is located. In FIG. 4, the water discharge control system 1 detects three areas where the captured object is located: area SG1 indicated by dotted lines, area SG2 indicated by dashed lines, and area SG3.
[0108] 4 shows an example in which a rectangular area is detected as the area where the object to be imaged is located, but the area where the object to be imaged is located is not limited to a rectangular area, and for example, the area where the object to be imaged is located may be detected in more detail. For example, the area where the object to be imaged is located may be detected in pixel units, or may be detected as a shape that follows the outer shape (contour) of the object to be imaged.
[0109] For example, the water discharge control system 1 detects the size of the imaged object as one of the indices used for water discharge control. For example, when the imaged object is an object to be discharged, the water discharge control system 1 detects the size of the object to be discharged. For example, the water discharge control system 1 may detect the size of a rectangular area such as areas SG1 to SG3. For example, the water discharge control system 1 may detect the size of the object to be discharged based on the number of pixels included in area SG1 in which the dish that is the object to be discharged is located. Note that when the water discharge control system 1 detects a shape that follows the outline (contour) of the object to be discharged, it may detect the size of the object to be discharged based on the number of pixels included within that outline. In this way, the water discharge control system 1 may control using the size of the object itself, or may control using the size of the detection result of the object (rectangular area, etc.).
[0110] Furthermore, the water discharge control system 1 classifies (determines) the type of each imaged object in the image IM1 using any image recognition technology. In FIG. 4, the water discharge control system 1 classifies the type of the imaged object located in area SG1 of the image IM1 as a utensil. Furthermore, the water discharge control system 1 classifies the type of the imaged objects located in areas SG2 and SG3 of the image IM1 as a human hand. Note that various conventional technologies can be applied to recognize objects contained in an image, and for example, image recognition technology utilizing various machine learning techniques such as deep learning may be used as appropriate.
[0111] Furthermore, the classification of the area in which the imaged object is located and the type may be performed by a single process. For example, when an image is input, the water discharge control system 1 may perform a process of classifying the area in which the imaged object is located and the type using an image recognition model that outputs information indicating the area and type of each imaged object in the input image. In this case, the water discharge control system 1 may input the image IM1 to the image recognition model, and estimate (determine) the size and type of each imaged object in the image IM1 based on the information indicating the area in which the imaged object is located and the type classification in the image IM1 output by the image recognition model.
[0112] In this way, the water discharge control system 1 uses any image recognition technology to detect the objects included in the image IM1 and classify (determine) the type of the detected objects. For example, the water discharge control system 1 uses any image recognition technology to determine to which of multiple types each of the objects detected in the image IM1 belongs.
[0113] For example, the water discharge control system 1 classifies (determines) the type of the imaged object as one of the indices used for water discharge control. For example, the water discharge control system 1 may classify the imaged object to one of a plurality of types based on individual names such as chopsticks, pot, plate, etc., into which type the imaged object belongs. For example, the water discharge control system 1 may classify the imaged object to one of a plurality of types based on general classifications such as tableware, hands, ingredients, etc., into which type the imaged object belongs. Furthermore, the water discharge control system 1 may classify the imaged object to one of a plurality of newly defined types such as water-splashing dishes, water-collecting dishes, etc.
[0114] It should be noted that any classification can be adopted for the multiple types into which the imaged objects are classified. For example, the multiple types may be types based on category classification. For example, the multiple types may be types based on category classification used in general object recognition or the like. For example, the multiple types may be three types: human hands, supplies, and others. Alternatively, for example, the multiple types may be four types: human hands, objects, food ingredients, and others. Alternatively, for example, the multiple types may be four types: human hands, objects, food ingredients, and others.
[0115] For example, the plurality of types may be types based on classification of uses, for example, the plurality of types may include types based on classification of uses for which the article is used.
[0116] For example, the multiple types may be types based on a classification of shapes. For example, the multiple types may include types based on a classification of the shape of the article. For example, the multiple types may include types based on a classification of whether the article has a shape that is prone to splashing water. For example, the multiple types may include types based on the degree of susceptibility of the shape of the article to splashing water.
[0117] For example, the multiple types may be types based on a classification of materials. For example, the multiple types may include types based on a classification of what material the article is made of. For example, the multiple types may include types based on a classification of whether the article is made of a material that is prone to splashing water. For example, the multiple types may include types based on the degree of susceptibility to splashing water of the material of the article.
[0118] The above-described classification of types is merely an example, and any type can be adopted as long as the desired processing can be realized. The multiple types may be types based on a combination of at least two of category classification, use classification, shape classification, and material classification. The types may also have a hierarchical relationship. In this case, for example, items and ingredients may belong to a lower level of supplies, tableware and cooking utensils may belong to a lower level of items, and vegetables and meat may belong to a lower level of ingredients. The above-described hierarchical relationship is merely an example, and any hierarchical relationship can be adopted, and may be three or more levels. For example, knives and bowls may belong to a lower level of cooking utensils.
[0119] For example, the water discharge control system 1 estimates (calculates) the distance between the water discharge port and the target object (object onto which water is discharged) as one of the indices used for water discharge control. For example, the water discharge control system 1 may calculate the distance using AI based on an image, or may estimate the distance based on the size of the user's hand.
[0120] For example, when an image is input, the water discharge control system 1 may estimate the distance between the water spout and the object (object to be discharged) using a distance estimation model that outputs information indicating the distance between the object to be discharged in the input image and a predetermined position (the position of the water spout). In this case, the water discharge control system 1 may input the image IM1 to the distance estimation model, and estimate (calculate) the distance between the dish that is the object to be discharged and the water spout 321 based on information indicating the estimated distance between the dish that is the object to be discharged in image IM1 and the water spout 321 output by the distance estimation model. Note that the above is merely an example, and the water discharge control system 1 may estimate the distance between the water spout 321 and the object (object to be discharged) using various information as appropriate. For example, the water discharge control system 1 may estimate the distance between the water spout 321 and the object (object to be discharged) based on the size of at least one of the areas SG2 and SG3 that include a person's hand.
[0121] <1-5. Example of water discharge flow rate control> Here, some examples of controlling the instantaneous water discharge flow rate will be described.
[0122] <1-5-1. Example of flow rate control according to size> First, an example of controlling the instantaneous water discharge flow rate will be described, as shown in Fig. 5. Fig. 5 is a diagram showing an example of controlling the instantaneous water discharge flow rate. Specifically, Fig. 5 is a diagram showing an example of controlling the instantaneous water discharge flow rate according to the size of the object to which water is discharged. For example, Fig. 5 shows a case where the instantaneous water discharge flow rate is controlled according to the size of the object.
[0123] Graph GR11 in Figure 5 shows the relationship between the size of an object and the instantaneous water discharge flow rate when the water discharge control system 1 controls the instantaneous water discharge flow rate according to the size of the object. In graph GR11, the vertical axis represents the instantaneous water discharge flow rate, and the horizontal axis represents the size of the object to which water is discharged. Graph GR11 shows the measurement results of the optimal instantaneous water discharge flow rate that makes it easy for the user to work, depending on the size of the object to which water is discharged.
[0124] For example, the plot in graph GR11 indicates the optimal instantaneous water discharge flow rate (measurement result) for the size of the object, and line LN11 in graph GR11 indicates the optimal instantaneous water discharge flow rate for the size of the object to which water is discharged (object) estimated based on the plot. In this way, the larger the object, the higher the instantaneous water discharge flow rate is preferable. Therefore, for example, the control unit 100 of the water discharge control system 1 controls the water discharge so that the instantaneous water discharge flow rate is higher the larger the object to which water is discharged (object).
[0125] <1-5-2. Examples of flow rate control according to type> Next, an example of controlling the instantaneous water discharge flow rate shown in Fig. 6 will be described. Fig. 6 is a diagram showing an example of controlling the instantaneous water discharge flow rate. Specifically, Fig. 6 is a diagram showing an example of controlling the instantaneous water discharge flow rate according to the type of object onto which water is discharged. For example, Fig. 6 shows a case where the instantaneous water discharge flow rate is controlled according to whether the object onto which water is discharged is an object or a human hand. Note that explanations of points similar to those explained in Fig. 5 etc. will be omitted as appropriate.
[0126] Graph GR21 in FIG. 6 shows the relationship between the size of each type and the instantaneous water discharge flow rate when the water discharge control system 1 controls the instantaneous water discharge flow rate according to the type and size.
[0127] As shown in Fig. 6, the instantaneous water discharge flow rate may be controlled in different ways depending on the type of object to which water is discharged. For example, the control unit 100 of the water discharge control system 1 controls the water discharge so that the instantaneous water discharge flow rate increases as the size of the object to which water is discharged increases, but controls the instantaneous water discharge flow rate to different values depending on the type of object.
[0128] For example, when the object to be discharged is an article, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate in accordance with the size of the object to be discharged, as shown by line LN21 in graph GR21. Also, when the object to be discharged is a human hand, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate in accordance with the size of the object to be discharged, as shown by line LN22 in graph GR21. In this way, regardless of the type of object, the larger the object, the higher the instantaneous water discharge flow rate, but the upper limit, lower limit, amount of change, etc. may be different.
[0129] As described above, the water discharge control system 1 may change the control of the instantaneous water discharge flow rate depending on the type of object to which water is discharged. Note that the above is just one example, and the hierarchical relationship of the instantaneous water discharge flow rate between an object and a human hand may also be different. Also, for example, in the case of a human hand, the water discharge control system 1 may control the instantaneous water discharge flow rate so that it does not change depending on the size. In this case, when the object to which water is discharged is a human hand, the water discharge control system 1 may control the water discharge at a constant instantaneous water discharge flow rate.
[0130] <1-5-3. Example of flow rate control according to distance> Next, an example of controlling the instantaneous water discharge flow rate shown in Fig. 7 will be described. Fig. 7 is a diagram showing an example of controlling the instantaneous water discharge flow rate. Specifically, Fig. 7 is a diagram showing an example of controlling the instantaneous water discharge flow rate according to the distance between the water discharge port and the object to which water is discharged. Note that explanations of points similar to those explained in Fig. 5, Fig. 6, etc. will be omitted as appropriate.
[0131] For example, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate according to the distance between the water discharge outlet and the object to which water is discharged, as shown by line LN31 in graph GR31. For example, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate so that the greater the distance between the water discharge outlet and the object to which water is discharged, the smaller the instantaneous water discharge flow rate becomes.
[0132] As described above, the water discharge control system 1 may change the control of the instantaneous water discharge flow rate depending on the distance between the water discharge outlet and the object to which water is discharged. Note that the above is an example of flow rate control using the distance between the water discharge outlet and the object to which water is discharged, and the slope of the change, the up-down relationship, etc. may also change. For example, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate so that the closer the distance between the water discharge outlet and the object to which water is discharged is, the smaller the instantaneous water discharge flow rate becomes.
[0133] <1-5-4. Example of flow rate control according to water discharge type> Next, an example of controlling the instantaneous water discharge flow rate shown in Fig. 8 will be described. Fig. 8 is a diagram showing an example of controlling the instantaneous water discharge flow rate. Specifically, Fig. 8 is a diagram showing an example of controlling the instantaneous water discharge flow rate according to the water discharge mode. For example, Fig. 8 shows a case where the instantaneous water discharge flow rate is controlled according to whether the water discharge mode is straight or shower. Note that explanations of points similar to those explained in Figs. 5 to 7 etc. will be omitted as appropriate.
[0134] Graph GR41 in Figure 8 shows the relationship between the size of the object and the instantaneous water discharge flow rate when the water discharge control system 1 controls the instantaneous water discharge flow rate according to the water discharge form. Graph GR41 shows the measurement results of the optimal instantaneous water discharge flow rate that makes it easy for the user to work with respect to the size of the object to which water is discharged for each water discharge form.
[0135] For example, the plot shown by the triangle in graph GR41 indicates the optimal instantaneous water discharge flow rate (measurement result) for the size of the object when the water discharge pattern is straight. Also, line LN41 in graph GR41 indicates the optimal instantaneous water discharge flow rate for the size of the object to be discharged when the water discharge pattern is straight, estimated based on the plot shown by the triangle.
[0136] Furthermore, for example, the plot shown by a rectangle in graph GR41 indicates the optimal instantaneous water discharge flow rate (measurement results) for the size of the object when the water discharge mode is a shower. Furthermore, line LN42 in graph GR41 indicates the optimal instantaneous water discharge flow rate for the size of the object to be discharged when the water discharge mode is a shower, estimated based on the plot shown by a rectangle.
[0137] As shown in Fig. 8, the instantaneous water discharge flow rate may be controlled to change differently depending on the water discharge form. For example, the control unit 100 of the water discharge control system 1 controls the water discharge so that the instantaneous water discharge flow rate increases as the size of the object onto which water is discharged increases, but controls the instantaneous water discharge flow rate to a different value depending on the water discharge form. For example, the control unit 100 of the water discharge control system 1 may reduce the change in the instantaneous water discharge flow rate relative to the size of the object when the water discharge form is a shower compared to when the water discharge form is a straight water discharge.
[0138] For example, when the water discharge mode is straight, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate according to the size of the object to which water is discharged, as shown by line LN41 in graph GR41. Also, when the water discharge mode is a shower, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate according to the size of the object to which water is discharged, as shown by line LN42 in graph GR41. In this way, regardless of the type of object, the larger the object, the higher the instantaneous water discharge flow rate, but the upper limit, lower limit, amount of change, etc. may be different.
[0139] <1-5-5. Example of flow rate control according to user preference> Next, an example of controlling the instantaneous water discharge flow rate shown in Figure 9 will be described. Figure 9 is a diagram showing an example of controlling the instantaneous water discharge flow rate. Specifically, Figure 9 is a diagram showing an example of controlling the instantaneous water discharge flow rate according to the user's preference. For example, Figure 9 shows a case where the user prefers a smaller instantaneous water discharge flow rate than average when the object is small, and prefers a larger instantaneous water discharge flow rate than average when the object is large. Note that explanations of points similar to those explained in Figures 5 to 8 will be omitted as appropriate.
[0140] Graph GR51 in Figure 9 shows the relationship between the magnitude of the instantaneous water flow rate and the magnitude of the instantaneous water flow rate when controlled at an instantaneous water flow rate that is estimated to be optimal on average regardless of the user (also called "average value control") and when controlled at an instantaneous water flow rate according to the user's preferences (also called "customized control").
[0141] 9, the instantaneous water discharge flow rate may be controlled (customized control) with a change different from the normal flow rate according to the user's preference. For example, the control unit 100 of the water discharge control system 1 controls the instantaneous water discharge flow rate with a change according to the user (customized control).
[0142] For example, when the user sets (specifies) a preferred instantaneous water discharge flow rate, the control unit 100 of the water discharge control system 1 may perform control of the instantaneous water discharge flow rate (customized control) in accordance with the size of the object to be discharged, as shown by line LN51 in graph GR51. Also, for example, when there is no setting by the user, the control unit 100 of the water discharge control system 1 may perform control of the instantaneous water discharge flow rate (average value control) in accordance with the size of the object to be discharged, as shown by line LN52 in graph GR51.
[0143] As described above, the water discharge control system 1 may perform customized control according to the user's settings. For example, some users prefer a low flow rate (e.g., prioritizing water conservation and reducing water splashing) based on the measurement results of the optimal instantaneous water discharge flow rate that is easy for the user to work with, while others prefer a high flow rate (e.g., prioritizing workability). Therefore, the water discharge control system 1 may be able to change the flow rate control according to the user's preferences, either through initial settings or by changing the settings each time. Furthermore, the water discharge control system 1 may be able to change the control method, such as setting the flow rate below the average value when the target object is small and setting the flow rate above the average value when the target object is large.
[0144] <1-5-6. Example of flow rate control according to contamination> Next, an example of controlling the instantaneous water discharge flow rate shown in Fig. 10 will be described. Fig. 10 is a diagram showing an example of controlling the instantaneous water discharge flow rate. Specifically, Fig. 10 is a diagram showing an example of controlling the instantaneous water discharge flow rate depending on whether or not there is dirt. For example, Fig. 10 shows a case where the instantaneous water discharge flow rate is controlled depending on the water discharge pattern and whether or not there is dirt. Note that explanations of points similar to those explained in Figs. 5 to 9 etc. will be omitted as appropriate.
[0145] Graph GR61 in FIG. 10 shows the relationship between the size of the object and the instantaneous water discharge flow rate when the water discharge control system 1 controls the instantaneous water discharge flow rate depending on the water discharge form and the presence or absence of dirt.
[0146] As shown in Fig. 10, the instantaneous water discharge flow rate may be controlled differently depending on the water discharge form and the presence or absence of dirt. For example, the control unit 100 of the water discharge control system 1 controls the water discharge so that the instantaneous water discharge flow rate increases as the size of the object onto which water is discharged increases, but controls the instantaneous water discharge flow rate to a different value depending on the water discharge form and the presence or absence of dirt. For example, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate so that it is smaller when there is dirt than when there is no dirt, regardless of the water discharge form.
[0147] For example, when the water discharge pattern is straight and there is no dirt, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate according to the size of the object to be discharged, as shown by line LN61 in graph GR61. For example, when the water discharge pattern is straight and there is dirt, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate according to the size of the object to be discharged, as shown by line LN62 in graph GR61.
[0148] Furthermore, for example, when the water discharge mode is a shower and there is no dirt, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate according to the size of the object to be discharged, as shown by line LN63 in graph GR61. Furthermore, for example, when the water discharge mode is a shower and there is dirt, the control unit 100 of the water discharge control system 1 may control the instantaneous water discharge flow rate according to the size of the object to be discharged, as shown by line LN64 in graph GR61. In this way, the water discharge control system 1 may reduce the flow rate below normal when there is dirt. This allows the water discharge control system 1 to further suppress splashing of dirt while also making it easier to remove oily dirt and the like through temperature control.
[0149] The above-described control is merely an example, and the water discharge control system 1 may control the instantaneous water discharge flow rate using various information.
[0150] <1-6. Example of processing by water discharge control system> The following first to third processes will be described below as examples of processes executed by the water discharge control system. For example, the water discharge control system 1 executes at least one of the first to third processes. Note that the water discharge control system 1 may execute water discharge control by combining each of the first to third processes. Furthermore, the following description will be given with the water discharge control system 1 as the processing subject, but the first to third processes may be executed by any device, such as the control unit 100 or various sensors such as the imaging unit 10, depending on the device configuration included in the water discharge control system 1.
[0151] <1-6-1. First processing flow> First, the flow of processing related to the first processing will be described using Fig. 11. Fig. 11 is a flowchart showing an example of the procedure related to the first processing executed by the water discharge control system. For example, Fig. 11 explains an example of processing when water discharge control is performed based on the type and size of the object to be discharged. As shown in Fig. 11, the water discharge control system 1 performs control by switching between automatic water discharge stop / flow rate control (automatic control) and semi-automatic control depending on the situation.
[0152] The water discharge control system 1 acquires the image recognition processing result (step S101). For example, the control unit 100 receives an image captured by the imaging unit 10 from the imaging unit 10, and detects an object (imaged object) included in the image and its position (coordinates, etc.) by performing image processing on the received image. Note that, for object detection and position detection from the image, various image processing techniques may be used as appropriate, as described in FIG. 4, and detailed description thereof will be omitted.
[0153] Then, the water discharge control system 1 determines whether or not there is a detection result from the operation detection unit (Step S102). For example, the control unit 100 determines whether or not there is an operation by the user relating to the control of the water discharge state.
[0154] If there is no user involved in controlling the water discharge state (step S102: None), the water discharge control system 1 determines the object of water discharge (step S103). For example, if the user does not perform an operation to change the water discharge state, the control unit 100 executes the control shown in steps S103 to S113. For example, if the user does not perform an operation to change the water discharge state, the control unit 100 sets the mode to a first mode, which will be described later, and executes automatic control (auto control). For example, the control unit 100 executes a process to determine whether an object (imaged object) is present within the water discharge area in the image captured by the imaging unit 10, and whether the moving speed of the object satisfies a predetermined standard.
[0155] When the water discharge control system 1 detects an object for water discharge (step S103: Yes), it executes acquisition of the water discharge mode (step S104). For example, when an object (imaged object) is present within the water discharge area and the moving speed of the object meets a predetermined standard, the control unit 100 determines that an object for water discharge has been detected, and acquires water discharge mode information indicating whether the water discharge mode is shower or straight. Note that the execution timing of step S104 is not limited to the timing shown in FIG. 11, and the water discharge control system 1 may execute the processing of step S104 at any timing before determining the flow rate.
[0156] Then, the water discharge control system 1 determines the type of the object to be discharged (step S105). For example, the control unit 100 classifies the type of the object to be discharged as either a type belonging to a tool or a human hand.
[0157] When the water discharge control system 1 determines that the type of the object to be discharged is a type that belongs to supplies (step S105: supplies), it determines the type of supplies (step S106). For example, when the control unit 100 determines that the type of the object to be discharged is a type that belongs to supplies, it classifies it as either an article or an ingredient.
[0158] When the water discharge control system 1 determines that the type of the object to be discharged is an article (step S106: article), it calculates the size of the article (step S107). For example, the control unit 100 estimates the size of the object to be discharged using the image captured by the imaging unit 10.
[0159] Then, the water discharge control system 1 discharges water at a flow rate according to the size and water discharge form of the article (step S108). For example, the control unit 100 controls the instantaneous water discharge flow rate according to the size and water discharge form of the article that is the water discharge target.
[0160] Furthermore, when the water discharge control system 1 determines that the type of the object to be discharged is food (step S106: food), it calculates the size of the food (step S109). For example, the control unit 100 estimates the size of the food, which is the object to be discharged, using the image captured by the imaging unit 10.
[0161] Then, the water discharge control system 1 discharges water at a flow rate according to the size of the food material and the water discharge pattern (step S110). For example, the control unit 100 controls the instantaneous water discharge flow rate according to the size of the food material, which is the object to be discharged, and the water discharge pattern.
[0162] The water discharge control system 1 does not have to distinguish (classify) the type of product. In this case, when the water discharge control system 1 determines in step S105 that the type of the object to be discharged water is a product, instead of the processes of steps S106 to S110, it may calculate the size of the product and discharge water at a flow rate according to the size and water discharge pattern of the product.
[0163] Furthermore, when the water discharge control system 1 determines that the type of object to be discharged water is a human hand (step S105: human hand), it calculates the size of the human hand (step S111). For example, when the control unit 100 determines that the type of object to be discharged water is a human hand, it estimates the size of the human hand, which is the object to be discharged water, using the image captured by the imaging unit 10.
[0164] Then, the water discharge control system 1 discharges water at a flow rate according to the size and water discharge form of the person's hand (step S112). For example, the control unit 100 controls the instantaneous water discharge flow rate according to the size and water discharge form of the person's hand, which is the object to be discharged water.
[0165] Furthermore, if the water discharge control system 1 has not detected an object to be discharged (step S103: No), it stops the water (step S113). For example, if there is no object (imaged object) within the water discharge area, or if the moving speed of the object does not meet a predetermined standard, the control unit 100 determines that the object to be discharged has not been detected, and controls the water discharge unit 30 to stop the water. Note that if the water discharge control system 1 is in a stopped state, it maintains that state.
[0166] When there is a user operation related to the control of the water discharge state (step S102: Yes), the water discharge control system 1 controls the water discharge state based on the detection result of the operation detection unit (step S114). For example, when the user performs an operation to change the water discharge state, the control unit 100 shifts the mode to a mode corresponding to the user's operation and controls the water discharge state. For example, when the user performs an operation to change the water discharge state, the control unit 100 shifts the mode to a second mode (described later) and performs semi-automatic control in which at least a portion of the control is controlled according to the user's operation.
[0167] In this way, through the first process, the water discharge control system 1 varies the water discharge control, such as the instantaneous water discharge flow rate, depending on the type and size of the object onto which water is discharged. This allows the water discharge control system 1 to discharge water appropriately depending on the type and size of the object onto which water is discharged. The water discharge control system 1 can execute control related to stopping and discharging water that is user-friendly.
[0168] <1-6-2. Second processing flow> It should be noted that the process shown in FIG. 11 is merely an example, and the water discharge control system 1 may also control water discharge according to the likelihood of water splashing. In this regard, the flow of the process will be explained as a process related to the second process using FIG. 12. FIG. 12 is a flowchart showing an example of the procedure related to the second process executed by the water discharge control system. For example, FIG. 12 explains an example of a process in which water discharge control is performed based on the type, size, and likelihood of water splashing of the object to be discharged. It should be noted that explanations of points similar to those explained in FIG. 11 will be omitted as appropriate.
[0169] The water discharge control system 1 acquires the image recognition processing result (Step S201). Then, the water discharge control system 1 determines whether or not there is a detection result from the operation detection unit (Step S202).
[0170] If there is no user involved in controlling the water discharge state (step S202: None), the water discharge control system 1 determines the object of water discharge (step S203). For example, if the user does not perform an operation to change the water discharge state, the control unit 100 executes the control shown in steps S203 to S212. For example, if the user does not perform an operation to change the water discharge state, the control unit 100 sets the mode to a first mode, which will be described later, and executes automatic control (auto control). For example, the control unit 100 executes a process to determine whether an object (imaged object) is present within the water discharge area in the image captured by the imaging unit 10, and whether the moving speed of the object satisfies a predetermined standard.
[0171] When the water discharge control system 1 detects an object onto which water is discharged (step S203: Yes), it executes acquisition of the water discharge form (step S204). Note that the execution timing of step S204 is not limited to the timing shown in Fig. 12, and the water discharge control system 1 may execute the processing of step S204 at any timing before determining the flow rate.
[0172] Then, the water discharge control system 1 determines the type of the object to be discharged (step S205). If the water discharge control system 1 determines that the type of the object to be discharged belongs to a product (step S205: product), it calculates the size of the product (step S206). For example, the control unit 100 estimates the size of the product, which is the object to be discharged, using the image captured by the imaging unit 10.
[0173] Then, the water discharge control system 1 determines the shape of the product (step S207). For example, the control unit 100 classifies the product as either a type that is prone to splashing water or a type that is not prone to splashing water.
[0174] When the water discharge control system 1 determines that the type of object to be discharged is prone to splashing (step S207: prone to splashing), it discharges water at a flow rate according to the size, water discharge form, and tendency to splash (step S208). For example, the control unit 100 controls the instantaneous water discharge flow rate according to the size, water discharge form, and tendency to splash of the object to be discharged.
[0175] Furthermore, if the water discharge control system 1 determines that the type of object to be discharged is unlikely to splash (step S207: unlikely to splash), it discharges water at a flow rate according to the size, water discharge form, and water splashing level of the item (step S209). For example, the control unit 100 controls the instantaneous water discharge flow rate according to the size, water discharge form, and water splashing level of the object to be discharged.
[0176] Furthermore, when the water discharge control system 1 determines that the type of object to be discharged water is a human hand (step S205: human hand), it calculates the size of the human hand (step S210). For example, when the control unit 100 determines that the type of object to be discharged water is a human hand, it estimates the size of the human hand, which is the object to be discharged water, using the image captured by the imaging unit 10.
[0177] Then, the water discharge control system 1 discharges water at a flow rate according to the size and water discharge pattern of the person's hand (step S211). Furthermore, if the water discharge control system 1 has not detected an object to be discharged (step S203: No), it stops the water (step S212).
[0178] When there is a user regarding the control of the water discharge state (step S202: Yes), the water discharge control system 1 controls the water discharge state based on the detection result of the operation detection unit (step S213). For example, when the user performs an operation to change the water discharge state, the control unit 100 shifts the mode to a mode (second mode, etc.) according to the user's operation and controls the water discharge state.
[0179] In this way, through the second process, the water discharge control system 1 varies the water discharge control, such as the instantaneous water discharge flow rate, depending on the shape of the object to be discharged, such as the tendency of the object to splash water. This allows the water discharge control system 1 to discharge water appropriately depending on the shape of the object to be discharged. The water discharge control system 1 can execute control related to stopping and discharging water that is easy for the user to use.
[0180] <1-6-3. Third processing flow> The water discharge control system 1 may also control water discharge according to the position of a person's hand. In this regard, the flow of the process will be explained as a process related to the third process using Fig. 13. Fig. 13 is a flowchart showing an example of the procedure related to the third process executed by the water discharge control system. Note that explanations of points similar to those explained in Fig. 11 and Fig. 12 will be omitted as appropriate.
[0181] The water discharge control system 1 acquires the image recognition processing result (Step S301). Then, the water discharge control system 1 determines whether or not there is a detection result from the operation detection unit (Step S302).
[0182] If there is no user controlling the water discharge state (step S302: NO), the water discharge control system 1 determines whether or not an object is present in the water discharge area (first area) (step S303). For example, if the user does not perform an operation to change the water discharge state, the control unit 100 executes the control shown in steps S303 to S313. For example, if the user does not perform an operation to change the water discharge state, the control unit 100 sets the mode to a first mode (described below) and executes automatic control (auto control). For example, the control unit 100 executes a process to determine whether or not an object (imaged object) is present in the water discharge area (first area) in the image captured by the image capture unit 10. Note that, similar to the first process and the second process, the control unit 100 may execute a process to determine whether or not an object (imaged object) is present in the water discharge area (first area) and whether the moving speed of the object satisfies a predetermined standard.
[0183] When the water discharge control system 1 detects an object in the water discharge area (first area) (step S303: Yes), it executes acquisition of the water discharge mode (step S304). For example, when the control unit 100 detects an object in the water discharge area (first area), it acquires water discharge mode information indicating whether the water discharge mode is shower or straight. Note that the execution timing of step S304 is not limited to the timing shown in FIG. 11, and the water discharge control system 1 may execute the processing of step S304 at any timing before determining the flow rate.
[0184] Then, the water discharge control system 1 determines the type of object in the water discharge area (step S305). For example, the control unit 100 classifies the type of object in the water discharge area as a type belonging to supplies such as an article or foodstuff, or as a human hand.
[0185] When the water discharge control system 1 determines that the type of object in the water discharge area is an item or foodstuff (step S305: supplies), it determines whether or not there is a hand in the second area (step S306). For example, when the control unit 100 determines that the type of object in the water discharge area is a type belonging to supplies, it determines whether or not there is a hand in the second area, which is an area outside the first area. For example, the second area may be an area surrounding the first area that is provided so as to surround the periphery of the first area. Note that the second area may be set to any range.
[0186] When the water discharge control system 1 detects a human hand in the second area (step S306: Yes), it determines the type of utensil (step S307). For example, when the control unit 100 determines that a human hand is located in the second area, it classifies the type of utensil located in the water discharge area (first area) as either an article or an ingredient.
[0187] When the water discharge control system 1 determines that the type of object in the water discharge area is an article (step S307: article), it calculates the size of the article (step S308). For example, the control unit 100 estimates the size (dimensions) of the article, which is the object in the water discharge area, using the image captured by the imaging unit 10.
[0188] Then, the water discharge control system 1 discharges water at a flow rate according to the size and water discharge form of the article (step S309). For example, the control unit 100 controls the instantaneous water discharge flow rate according to the size and water discharge form of the article, which is the object in the water discharge area.
[0189] Furthermore, when the water discharge control system 1 determines that the type of object in the water discharge area is food (step S307: food), it discharges water at a flow rate according to the food and water discharge pattern (step S310). For example, the control unit 100 controls the instantaneous water discharge flow rate according to the food, which is the object in the water discharge area, and the water discharge pattern. Note that the control unit 100 may calculate the size of the food, which is the object in the water discharge area, and control the instantaneous water discharge flow rate according to the size of the food.
[0190] If the water discharge control system 1 does not detect a human hand in the second area (step S306: No), it stops the water flow (step S311). For example, if the control unit 100 determines that a human hand is not located in the second area, it controls the water discharge unit 30 to stop the water flow. Note that if the water discharge control system 1 is in a stopped state, it maintains that state.
[0191] Furthermore, if the water discharge control system 1 determines that the type of object in the water discharge area is a human hand (step S305: human hand), the water discharge control system 1 discharges water at a flow rate according to the human hand and water discharge form (step S312). For example, the control unit 100 controls the instantaneous water discharge flow rate according to the human hand, which is the object in the water discharge area, and the water discharge form. Note that the control unit 100 may calculate the size of the human hand, which is the object in the water discharge area, and control the instantaneous water discharge flow rate according to the size of the human hand.
[0192] Furthermore, if the water discharge control system 1 has not detected an object in the water discharge area (step S303: No), it stops the water (step S313). For example, if the control unit 100 has not detected an object in the water discharge area (first area), it controls the water discharge unit 30 to stop the water. Note that if the water discharge control system 1 is in a stopped state, it maintains that state.
[0193] When there is a user regarding the control of the water discharge state (step S302: Yes), the water discharge control system 1 controls the water discharge state based on the detection result of the operation detection unit (step S314). For example, when the user performs an operation to change the water discharge state, the control unit 100 shifts the mode to a mode (second mode, etc.) according to the user's operation and controls the water discharge state.
[0194] In this way, through the third process, the water discharge control system 1 varies the water discharge control, such as the instantaneous water discharge flow rate, depending on the position of the person's hand. This allows the water discharge control system 1 to perform appropriate water discharge according to the position of the person's hand. The water discharge control system 1 can execute control related to stopping and discharging water that is user-friendly.
[0195] <1-7. Effects of the First Embodiment> As described above, the water discharge control system 1 controls the instantaneous water discharge flow rate (water pressure) from the water discharge section based on the size and type of the object (object to be discharged water) from the captured image, or the distance between the water discharge port and the object, thereby controlling the water discharge based on the size and type of the object, and allowing the user to control the water discharge at a water discharge flow rate that is easier for them to work with.
[0196] For example, it is desirable to discharge water at high water pressure for large dishes such as pots and cutting boards regardless of their degree of dirtiness, and discharging water at low water pressure (low instantaneous water discharge flow rate) in response to less dirtiness poses a major problem in terms of usability. Therefore, the water discharge control system 1 controls the instantaneous water discharge flow rate (water pressure) from the water discharge unit based on the type and size of the object (object to be discharged water) from the captured image, thereby discharging water at an appropriate instantaneous water discharge flow rate, etc., based on the type and size of the object.
[0197] As described above, the water discharge control system 1 according to the first embodiment can appropriately control water discharge by controlling water discharge and stopping according to at least one of the type and size of the object onto which water is to be discharged, and the distance between the water discharge port and the object, making it possible to provide a system that is easy to use. In this way, the water discharge control system 1 according to the first embodiment can execute control related to water discharge and stopping that is easy for the user to use.
[0198] 2. Second embodiment Here, depending on the situation, it may be more convenient for the user to perform some control in response to user operation rather than automatic control based on the state of the object detected from the image. Therefore, as described above, the water discharge control system 1 may perform control by appropriately switching between the first mode and the second mode depending on the situation. A specific example of this process will be described below as the second embodiment.
[0199] In the water discharge control system 1 according to the second embodiment, explanations of the same points as those in the water discharge control system 1 according to the first embodiment will be omitted as appropriate. For example, the water discharge control system 1 according to the second embodiment has the same configuration and arrangement as the water discharge control system 1 according to the first embodiment, and therefore explanations of the configuration and arrangement will be omitted.
[0200] The control unit 100 of the water discharge control system 1 according to the second embodiment controls the water discharge state by switching between a first mode and a second mode. For example, the first mode is a mode in which automatic water discharge stop and flow rate control (automatic control) is performed based on the state of the object to be discharged detected from an image. For example, the second mode is a mode in which some of the control based on the determination result of the first mode (also referred to as "control in the first mode") is prohibited and control is performed based on the user's operation (semi-automatic control). For example, the second mode is a mode in which some of the control in the first mode, which is control based on the determination result regarding the state of the object to be imaged, is prohibited and control is performed based on the user's operation (semi-automatic control). Note that the second mode may include multiple water discharge control states. In this case, the control unit 100 may control the water discharge state by switching between the multiple water discharge control states (also referred to as "partial second modes") during operation in the second mode.
[0201] For example, the control unit 100 according to the second embodiment executes the following process. The control unit 100 determines the state of the object detected from the image captured by the imaging unit 10. The control unit 100 detects a user operation for controlling the water discharge state of the water discharge unit 30. The control unit 100 controls the water discharge state of the water discharge unit 30 based on at least one of the determination result of the state of the object or the user operation.
[0202] Based on the user's operation, the control unit 100 sets a first mode in which the water discharge state is controlled based on the determination result regarding the state of the object being imaged, and a second mode in which the control of at least some of the water discharge state is prohibited based on the determination result regarding the state of the object being imaged.
[0203] In the first mode, the control unit 100 controls the water discharge state based on the state of the object to be discharged. In the first mode, the control unit 100 determines whether the object to be imaged is an object to be discharged, and controls the discharge of water onto the object to be discharged. The control unit 100 determines whether the object to be imaged is an object to be discharged. Of the objects to be imaged, the control unit 100 determines that an object that has a predetermined moving speed is an object to be discharged. Of the objects to be imaged, the control unit 100 determines that an object that is within the first region is an object to be discharged.
[0204] When the second mode ends, the control unit 100 cancels the prohibition on at least some of the water discharge control based on the determination result that was prohibited in the second mode. The control unit 100 determines that the second mode has ended when it detects that the kitchen space has been used up in the second mode. The control unit 100 determines that the second mode has ended when the water stop state in the second mode continues for a certain period of time.
[0205] The second mode may include a plurality of water discharge control states. When the control unit 100 detects a first mode switching operation by the user (e.g., corresponding to "operation 1" to switch to the first mode in FIG. 17) in any water discharge control state of the second mode (partial second mode), the control unit 100 ends the second mode and transitions to the first mode. When the control unit 100 detects a return operation by the user in any water discharge control state of the second mode (partial second mode), the control unit 100 returns to the water discharge control immediately before the operation.
[0206] For example, when the control unit 100 detects a back operation by the user, it returns the mode (water discharge control state) to the source of the transition in the operation before the back operation. For example, when the control unit 100 detects a back operation by the user, if the source of the transition in the operation before the back operation is the first mode, it returns the mode (water discharge control state) to the first mode. For example, when the control unit 100 detects a back operation by the user, if the source of the transition in the operation before the back operation is a certain partial second mode (e.g., partial second mode #3), it returns the mode (water discharge control state) to that partial second mode (e.g., partial second mode #3).
[0207] For example, in the second mode, the control unit 100 controls at least a part of the water discharge state based on the prohibited determination result, based on the user's operation. The control unit 100 detects the user's operation based on the image captured by the imaging unit 10. The control unit 100 detects the operation of the hand outside the first area.
[0208] The water discharge control system 1 switches the water discharge control state as follows and performs water discharge in response to the detection of the user's operation by the control unit 100. For example, the water discharge control system 1 switches the water discharge control state and performs water discharge in response to the second to eighth mode switching operations by the user shown below.
[0209] When the water discharge control system 1 detects a second mode switching operation by the user (e.g., corresponding to "Operation 2" to "Continuous Water Discharge - Water - Straight" in FIG. 17), it prohibits all control based on the determination result of the first mode, and continues to discharge water at a fixed predetermined instantaneous water flow rate and temperature, regardless of the object, until the user performs the next operation or the second mode ends. Also, when the water discharge control system 1 detects a third mode switching operation by the user (e.g., corresponding to "Operation 3" to "Stop Water Discharge" in FIG. 17), it prohibits all control based on the determination result of the first mode, and stops water discharge, regardless of the object, until the user performs the next operation or the second mode ends.
[0210] When the water discharge control system 1 detects a fourth mode switching operation by the user (e.g., corresponding to "Operation 4" to "Auto Hot Water / Straight" in FIG. 17), it prohibits only the temperature control based on the judgment result of the first mode, and controls the temperature to the changed temperature by the user's operation, regardless of the object, until the user performs the next operation or the second mode ends. Also, when the water discharge control system 1 detects a fifth mode switching operation by the user (e.g., corresponding to "Operation 5" to "Continuous Water Discharge / Purified Water / Straight" in FIG. 17), it prohibits the control of water discharge stop, flow rate, temperature, and water type based on the judgment result of the first mode, and discharges purified water at a fixed predetermined instantaneous water discharge flow rate and temperature, regardless of the object, until the user performs the next operation or the second mode ends.
[0211] When the water discharge control system 1 detects a sixth mode switching operation by the user, it prohibits the control of the water discharge form based on the judgment result of the first mode, and controls the water discharge form to the changed form by the user's operation until the user performs the next operation or until the end of the second mode. Also, when the water discharge control system 1 detects a seventh mode switching operation by the user (for example, corresponding to "Operation 7" going to "Water accumulation (ratio) - Water - Straight" in Fig. 17), it prohibits the water discharge stop and instantaneous flow rate control for the water discharge target in the first mode, and starts water discharge if there is an object in the water discharge area, regardless of whether the object being imaged is the water discharge target or not, and stops water discharge if the amount of water accumulation in the object estimated based on the image meets predetermined conditions.
[0212] When the water discharge control system 1 detects an eighth mode switching operation by the user, it prohibits water discharge stop and flow rate control based on the first mode determination result, and starts water discharge at a predetermined flow rate (metered water discharge) regardless of the presence or absence of an object. For example, the control unit 100 detects various user operations such as the first to eighth mode switching operations and the return operation by the user based on images captured by the imaging unit 10. Note that each of the various user operations such as the first to eighth mode switching operations and the return operation may be an operation by the user such as a hand movement (hand signs, etc.) or a gesture by the user.
[0213] <2-2. Mode Examples of the Second Embodiment> Below, several example modes of the second embodiment will be described assuming the above-mentioned processing. First, the example modes shown in FIG. 14 will be described. FIG. 14 is a diagram showing an example of the first mode and the second mode according to the second embodiment. For example, FIG. 14 shows the first mode and the second mode including five partial second modes as an example. For example, the dotted bidirectional arrows connecting the modes in FIG. 14 indicate an example of a mode to which direct transition can be made.
[0214] As shown in FIG. 14, the water discharge status includes five elements: water discharge stop, flow rate, temperature, type, and water discharge form (also simply referred to as "form"). Note that the water discharge status elements shown in FIG. 14 are merely an example, and the water discharge status elements may be any elements. For example, the water discharge status may include six or more elements, or may include four or fewer elements. For example, if the type is an element that also includes temperature aspects such as cold water, hot water, purified water, etc., the water discharge status may include four elements: water discharge stop, flow rate, type, and form, without including the element of temperature.
[0215] In Fig. 14, in the first mode, the water discharge control system 1 automatically controls at least three of the five elements of the water discharge state, namely, water discharge stop, flow rate, and temperature (the hatched portion of the first mode in Fig. 14), without relying on user operation. For example, in the first mode, the water discharge control system 1 controls water discharge stop, flow rate, and temperature according to the determination result of the state of the object to be discharged that is included in the image captured by the imaging unit 10. Note that in the first mode, the water discharge control system 1 may automatically control all elements, namely, water discharge stop, flow rate, temperature, type, and form.
[0216] Furthermore, the partial second mode (hereinafter also referred to as "partial second mode #1") labeled "Continuous Water Discharge (Water)" in FIG. 14 corresponds to the second mode of the water discharge control state in which water is continuously discharged at a predetermined flow rate. In partial second mode #1, the water discharge control system 1 prohibits the same control as in the first mode for the three elements of water discharge stop, flow rate, and temperature that were subject to automatic control in the first mode. In partial second mode #1 shown in FIG. 14, the water discharge control system 1 controls water discharge stop by continuously discharging water, the flow rate by fixing it at a predetermined flow rate, and the temperature by controlling the water discharge state. For example, in partial second mode #1, the water discharge control system 1 may control at least some of the five elements of the water discharge state in response to user operation. For example, when the user performs a second mode switching operation, the water discharge control system 1 switches the mode to partial second mode #1.
[0217] Furthermore, the partial second mode labeled "water discharge stopped" in FIG. 14 (hereinafter also referred to as "partial second mode #2") corresponds to the second mode of water discharge control state in which water is not discharged. In partial second mode #2, the same control as in the first mode is prohibited for the three elements of water discharge stop, flow rate, and temperature that were subject to automatic control in the first mode. In partial second mode #2 shown in FIG. 14, the water discharge control system 1 controls water discharge stop in a water discharge state in which water discharge is stopped (stopped). For example, when the user performs the third mode switching operation, the water discharge control system 1 switches the mode to partial second mode #2.
[0218] Furthermore, the partial second mode labeled "Auto (Hot Water)" in FIG. 14 (hereinafter also referred to as "Partial Second Mode #3") corresponds to the second mode of the water discharge control state in which hot water is constantly discharged. In Partial Second Mode #3, the water discharge control system 1 prohibits the same control of temperature as in the first mode among the three elements of water discharge stop, flow rate, and temperature that were subject to automatic control in the first mode. In Partial Second Mode #3 shown in FIG. 14, the water discharge control system 1 controls the temperature in a state in which hot water is constantly discharged. For example, in Partial Second Mode #3, the water discharge control system 1 may control at least some of the five elements of the water discharge state in response to user operation. For example, when the user performs the fourth mode switching operation, the water discharge control system 1 switches the mode to Partial Second Mode #3.
[0219] Furthermore, the partial second mode (hereinafter also referred to as "partial second mode #4") labeled "continuous water discharge (purified water)" in FIG. 14 corresponds to the second mode of the water discharge control state in which purified water is continuously discharged at a predetermined flow rate. In partial second mode #4, the water discharge control system 1 prohibits the same control as in the first mode for the three elements of water discharge stop, flow rate, and temperature that were subject to automatic control in the first mode. In partial second mode #4 shown in FIG. 14, the water discharge control system 1 controls water discharge stop by continuous water discharge, the flow rate by a fixed predetermined flow rate, the temperature by water, and the type of water by purified water. For example, in partial second mode #4, the water discharge control system 1 may control at least some of the five elements of the water discharge state in response to user operation. For example, when the user performs the fifth mode switching operation, the water discharge control system 1 switches to partial second mode #4.
[0220] Note that the partial second mode shown in FIG. 14 is merely an example, and the second mode may include a partial second mode (hereinafter also referred to as "partial second mode #5") that prohibits the same control as in the first mode for the form. In partial second mode #5, the water discharge control system 1 prohibits the same control as in the first mode for at least the form of the five elements of the water discharge state. For example, in partial second mode #5, the water discharge control system 1 may control at least some of the five elements of the water discharge state in response to a user's operation. For example, when the user performs a sixth mode switching operation, the water discharge control system 1 switches the mode to partial second mode #5.
[0221] Furthermore, the partial second mode (hereinafter also referred to as "partial second mode #6") labeled "Water Accumulation (Ratio)" in FIG. 14 corresponds to a second mode of water discharge control state in which water is discharged at a predetermined flow rate until a predetermined amount of water accumulates (is discharged), and then the water stops. In partial second mode #6, the water discharge control system 1 prohibits the same control as in the first mode for the three elements of water discharge stop, flow rate, and temperature that were subject to automatic control in the first mode. In partial second mode #6 shown in FIG. 14, the water discharge control system 1 stops water discharge when water accumulates, fixes the flow rate at a predetermined flow rate, and controls the temperature while the water is being discharged. For example, in partial second mode #6, the water discharge control system 1 may control at least some of the five elements of the water discharge state in response to user operation. For example, when the user performs the seventh mode switching operation, the water discharge control system 1 switches to partial second mode #6.
[0222] The second mode may include a partial second mode (hereinafter also referred to as "partial second mode #7") in which light water discharge is performed. In partial second mode #7, the water discharge control system 1 prohibits the same control as in the first mode for at least the water discharge stoppage among the five elements of the water discharge state. For example, in partial second mode #7, the water discharge control system 1 may control at least some of the five elements of the water discharge state in response to user operation. For example, when the user performs the eighth mode switching operation, the water discharge control system 1 switches the mode to partial second mode #7.
[0223] In this way, the water discharge control system 1 switches modes in response to various operations by the user. For example, the first mode switching operation is an operation for setting the mode to the first mode. The second mode switching operation is an operation for switching to a mode for continuous water discharge. The third mode switching operation is an operation for switching to a mode for stopping water discharge. The fourth mode switching operation is an operation for switching to a mode for temperature control (hot water / cold water). The fifth mode switching operation is an operation for switching to a mode for type control (purified water). The sixth mode switching operation is an operation for switching to a mode for form control (shower). The seventh mode switching operation is an operation for switching to a mode for proportional water storage. The eighth mode switching operation is an operation for switching to a mode for metered water discharge.
[0224] It should be noted that the modes shown in Fig. 14 are merely examples, and any patterns can be adopted for the first mode and the second mode. For example, the first mode and the second mode may be patterns as shown in Figs. 15 and 16. Fig. 15 is a diagram showing an example of the first mode and the second mode according to the second embodiment. Fig. 16 is a diagram showing an example of the second mode according to the second embodiment. It should be noted that explanations of points similar to those explained in Fig. 14 etc. will be omitted as appropriate.
[0225] 15 and 16 show cases where the water discharge state includes five elements: water discharge stop, flow rate, temperature, type, and water discharge form (form). The top row of modes in Fig. 15 indicates the first mode, and the other rows in Fig. 15 and the rows in Fig. 16 indicate second modes (plurality of partial second modes). For example, the hatched areas for each partial second mode may indicate elements of the water discharge state that are prohibited from being controlled in the same way as in the first mode.
[0226] The water discharge control system 1 may perform various controls. For example, the water discharge control system 1 may change the first mode setting (default). The water discharge control system 1 may change the type and form. For example, the water discharge control system 1 may control the type and form based on an image. The water discharge control system 1 may turn off (fix) flow rate or temperature control.
[0227] Here, an example of the relationship between user operations and mode transitions will be described with reference to Fig. 17. Fig. 17 is a diagram showing an example of the relationship between operations and transitions in the first mode and the second mode according to the second embodiment. Note that explanations of points similar to those explained in Figs. 14 to 16 etc. will be omitted as appropriate.
[0228] This indicates that direct transitions (transitions) are possible between modes connected by arrows in Figure 17. For example, this indicates that direct transitions (transitions) are possible between modes connected by arrows, from the mode at the start of the arrow to the mode at the end of the arrow. For example, this indicates that direct transitions (transitions) are possible between modes connected by bidirectional arrows.
[0229] The seven ellipses shown within the frame of the second mode in Fig. 17 correspond to the respective partial second modes. That is, Fig. 17 shows a case where the second mode has seven partial second modes. Of the seven partial second modes, the partial second modes shown by the solid ellipses indicate partial second modes to which the user can switch (transition) from the first mode with a single operation. Of the seven partial second modes, the partial second modes shown by the dotted ellipses indicate partial second modes to which the user cannot switch (transition) from the first mode with a single operation.
[0230] For example, the partial second mode indicated by "Continuous Water Discharge Cold Water - Straight" in FIG. 17 corresponds to the partial second mode #1 described in FIG. 14. The partial second mode indicated by "Water Discharge Stop" in FIG. 17 corresponds to the partial second mode #2 described in FIG. 14. The partial second mode indicated by "Automatic Hot Water - Straight" in FIG. 17 corresponds to the partial second mode #3 described in FIG. 14. The partial second mode indicated by "Continuous Water Discharge Purified Water - Straight" in FIG. 17 corresponds to the partial second mode #4 described in FIG. 14. The partial second mode indicated by "Water Storage (Ratio) Cold Water - Straight" in FIG. 17 corresponds to the partial second mode #6 described in FIG. 14.
[0231] The water discharge control system 1 may switch modes and control water discharge based on the operations and mode transitions shown in Fig. 17. For example, after switching from the first mode to the second mode, the water discharge control system 1 may return to the first mode if the user performs the same operation. For example, the water discharge control system 1 may transition to the automatic (hot water / straight) mode in response to the user's operation corresponding to "operation 4" in Fig. 17 (fourth mode switching operation), and then return to the first mode (default) in response to the user's operation corresponding to "operation 4" in Fig. 17 (fourth mode switching operation).
[0232] Furthermore, for example, in the water discharge control system 1, the user can change the control within the second mode by operating during the second mode, and for example, it is possible to transition to a mode that cannot be controlled (for example, cannot transition to the first mode) with one action (one operation). For example, the water discharge control system 1 may transition to the automatic (hot water / straight) mode in response to a user operation (fourth mode switching operation) corresponding to "operation 4" in Fig. 17, and then transition to the automatic (hot water / shower) mode in response to a sixth mode switching operation, thereby transitioning to a mode that cannot be transitioned to the first mode with one operation.
[0233] As described above, the water discharge control system 1 controls water discharge using various modes. For example, the first mode is a mode for controlling the water discharge state (water discharge stop, flow rate, temperature, type, and form) based on a captured image. Also, for example, the second mode is a mode for prohibiting at least a portion of the control of the water discharge state based on the captured image in the first mode in response to a user's operation. Furthermore, the water discharge control system 1 is capable of not only control between the first mode and the second mode, but also control within the second mode (partial second mode), such as changing from continuous water discharge to water discharge stop or purified water. Note that the above is just one example, and the second mode may have various partial second modes, such as two patterns (partial second modes) with different flow rates for controlling continuous water discharge (water).
[0234] The water discharge control system 1 may have various configurations other than those described above. For example, the water discharge control system 1 may have a control change input unit that allows the user to change the control content in each mode or water discharge control state. For example, in the water discharge control system 1, the user can change each water discharge control setting in the first mode and the second mode using the control change input unit.
[0235] When an operating device such as an operation panel is provided on the kitchen main body 2, the water discharge control system 1 may have the operating device as a control change input unit. In this case, the operating device may have a display and input reception function, such as a touch panel, and may display the control content for each mode and water discharge control state and receive changes made by the user. The operating device transmits change information indicating the received changes made by the user to the control unit 100. The control unit 100, which has received the change information indicating the changes made by the user, changes the control content for each mode and water discharge control state based on the received change information.
[0236] <2-4. Effects of the Second Embodiment> Through the above-described processing, the water discharge control system 1 according to the second embodiment can achieve both automatic water discharge control based on captured images and semi-automatic water discharge control that can be operated at the user's discretion. For example, the water discharge control system 1 normally performs automatic control that takes into account the user's intentions, but in cases where users' preferences differ, the system can be operated at the user's discretion, making it possible to control water discharge in accordance with a wide variety of kitchen scenes and user preferences.
[0237] As described above, the water discharge control system 1 according to the second embodiment can appropriately control water discharge by switching between a plurality of modes such as the first mode and the second mode to control water discharge and stop, making it possible to provide a system that is easy to use. In this way, the water discharge control system 1 according to the second embodiment can execute control related to water discharge and stop that is easy for the user to use.
[0238] <3. Other configuration examples> The device configuration of the water discharge control system 1 shown in FIG. 2 is merely an example, and the water discharge control system 1 can adopt any device configuration. The water discharge control system 1 can be applied to various configurations as long as it is capable of executing at least some of the processes described above. For example, the water discharge control system 1 may be applied to a configuration in which purified water is controlled to be discharged separately from cold water and hot water. An example of the configuration of the water discharge control system 1 in this case will be described using FIG. 18. FIG. 18 is a diagram showing an example of another configuration of the water discharge control system.
[0239] Figure 18 shows an example in which purified water is supplied to water discharger 30 from a system separate from that for raw water and hot water. In the configuration example shown in Figure 18, water discharge control system 1 includes water purifier 82 that purifies raw water supplied from water supply 80 via water purification valve 102. In this case, purified water is discharged from water discharger 30 in response to operation of water purifier 82 by the user. For example, water discharge control system 1 may control water discharge for only two types of water, raw water and hot water.
[0240] <4. First and second embodiments, etc.> The water discharge control system 1 may execute a combination of the processes shown in the first and second embodiments. For example, the water discharge control system 1 may execute a combination of the various processes described above.
[0241] In the above-described embodiment, the water discharge control system 1 has been described using a kitchen as the application location, but it can be applied to any wet space where utensils can be used, and for example, it may be applied to a wash space provided in a toilet space or a place where water discharge and stopping actions such as hand washing are performed, such as a bathroom vanity. Note that the above-described embodiments and modified examples can be combined as appropriate within the scope of not causing any contradiction in the processing content.
[0242] Further advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
