Abstract
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, there are hopes for the development of systems that automatically understand a person's intention and appropriately control the faucet without the person operating it. For example, there is technology that controls the water flow and temperature according to the situation based on images captured by a camera (for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent No. 7330074 Summary of the Invention [Problem to be solved by the invention]
[0004] However, the above-mentioned conventional technology leaves room for improvement. For example, even in the same work situation, the flow rate and temperature that are most comfortable for different people vary. While the conventional technology allows for washing a dirty pot at a temperature not too hot by discharging water below 50°C onto the pot, there are many different types of people, such as those who prefer cold water, lukewarm water, or hot water. Therefore, the desired water discharge and the desired water discharge direction often differ from person to person. Therefore, controlling the water discharge solely automatically can result in poor usability for users. Furthermore, while voice control of the temperature is also envisioned, even users themselves have difficulty setting the temperature and flow rate without actually touching or visually checking the temperature. Therefore, fully automatic control can sometimes make it difficult for users to control the water discharge in a way that is user-friendly. Thus, the above-mentioned conventional technology leaves room for improvement, and there is a need for user-friendly control of the water discharge and stop.
[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 section, a detection section that detects at least the water discharge area, a judgment section that judges the state of the object of water discharge detected by the detection section, an automatic water discharge control section that generates a control signal to control the water discharge state from the water discharge section based on the judgment result of the judgment section, an automatic water discharge switching section that switches the water discharge state based on the control signal, a manual water discharge operation section that can be manually operated to control the water discharge state from the water discharge section, and a manual water discharge switching section that switches the water discharge state based on the manual operation, wherein the manual water discharge switching section is capable of switching the water discharge state from the water discharge section independently of the control signal when controlled by the control signal generated by the automatic water discharge control section, and the water discharge state from the water discharge section, when in a first water discharge state by the automatic water discharge switching section, is changed to a second water discharge state by a first operation on the manual water discharge operation section, and further, when the first operation on the manual water discharge operation section is released, returns to the first water discharge state.
[0007] For example, even when the water discharge state is controlled automatically, users have different preferences for fine adjustments of flow rate and water temperature. Therefore, completely automatic control would prevent fine adjustments, potentially reducing user convenience. Therefore, according to one embodiment of the water discharge control system, a manual water discharge operation unit that can be manually operated to control the water discharge state from the water discharge unit allows the water discharge state from the water discharge unit to be switched independently of the control signal generated by the automatic water discharge control unit during control by the control signal. This allows for fine adjustments to be made manually while maintaining automatic control as the basis. This allows for more precise adjustments to be made by the user. Furthermore, the water discharge control system allows for fine adjustments to be made each time the system is used, preventing any temporary changes from affecting the system later, ensuring stable water discharge during automatic control. Therefore, the water discharge control system can perform water discharge stop control in a user-friendly manner.
[0008] The water discharge control system according to one aspect of the embodiment further includes a hot water passage through which hot water is supplied from a hot water supply source and a water passage through which water is supplied from a water supply source, and the manual water discharge switching unit is connected to the hot water passage and the water passage and has the function of mixing the hot water and water supplied through the hot water passage and the water passage, and the automatic water discharge switching unit is equipped with a flow rate adjustment valve capable of adjusting the water discharge flow rate from the water discharge unit, and the flow rate adjustment valve is located downstream of the manual water discharge switching unit.
[0009] According to one aspect of the embodiment, the water discharge control system has a manual water discharge switching unit that has the function of mixing cold and hot water, which allows manual adjustment of the temperature, and allows manual adjustment of both the temperature and the flow rate. Therefore, the water discharge control system can perform control related to water discharge stop that is easy for the user to use.
[0010] In one aspect of the embodiment, the water discharge control system has an automatic water discharge switching unit that includes a water valve and a hot water valve, the water valve being provided on the water passage, and the hot water valve being provided on the hot water passage.
[0011] According to one aspect of the embodiment, the water discharge control system allows for hot and cold water switching, i.e., temperature control, not only by manual operation but also by automatic control, making it possible to simply switch between hot and cold water not only manually but also automatically. Therefore, the water discharge control system can execute control related to water discharge stop that is user-friendly. Furthermore, the water discharge control system allows for simple control by having independent hot and cold water valves.
[0012] In one aspect of the embodiment, in the water discharge control system, the automatic water discharge control unit automatically controls at least the flow rate based on the determination result by the determination unit, and does not perform temperature control based on the determination result by the determination unit.
[0013] According to a water discharge control system according to one aspect of the embodiment, flow rate adjustment is possible both manually and automatically, while temperature adjustment is only manual. In this way, by eliminating automatic temperature adjustment in the water discharge control system, automatic changes in water temperature are suppressed, making it easier for individuals to use. Therefore, the water discharge control system can execute control related to water discharge stop that is easy for users to use.
[0014] In one aspect of the embodiment, the water discharge control system includes an automatic water discharge switching unit equipped with a water type switching valve, which is located downstream of the water supply source and on a water passage branched off from the upstream side of the manual water discharge switching unit, and the flow path from the water type switching valve merges with the flow path from the manual water discharge switching unit downstream of the manual water discharge switching unit.
[0015] According to the water discharge control system of one aspect of the embodiment, the uses of purified water, functional water (alkaline water, etc.) are limited, so that it can be used conveniently by only using automatic control. Therefore, the water discharge control system can execute control related to stopping water discharge that is convenient for the user.
[0016] In the water discharge control system according to one aspect of the embodiment, the detection unit is provided above the water discharge unit.
[0017] In one embodiment of the water discharge control system, the sensor is located above the water discharge unit, allowing it to detect objects including the sink and its surrounding area. This allows it to identify the worker and their task, making it possible to identify the user and the purpose of use, and it becomes possible to finely control the water discharge through automatic control or control the water discharge according to the user's purpose. Therefore, the water discharge control system can execute control related to water discharge and stopping that is user-friendly.
[0018] In the water discharge control system according to one aspect of the embodiment, the detection unit is provided in the water discharge unit.
[0019] According to one aspect of the embodiment, the water discharge control system has a sensor in the water discharge section, which allows for detailed detection of objects in the area within the sink, thereby improving the accuracy of determining the state of the object. Furthermore, the water discharge control system has no obstructions, such as the water discharge section, within the sensor's detection range, improving the sensor's detection accuracy. Therefore, the water discharge control system can perform control related to water discharge stoppage that is user-friendly.
[0020] In one aspect of the embodiment, the water discharge control system includes a water discharge pipe extending from the base end toward the tip end, and a water discharge outlet member that is detachably held at the tip end of the water discharge pipe and has a water discharge outlet, a water discharge hose that is movable inside the water discharge pipe in the extension direction of the water discharge pipe, and the flow rate adjustment valve is provided outside the water discharge pipe.
[0021] According to one aspect of the embodiment, the water discharge control system includes a water discharge outlet member that is detachably attached to the tip of the water discharge pipe and has a water discharge outlet, which allows the user to move the water discharge outlet to a desired position. Therefore, the water discharge control system can perform control related to water discharge stop that is easy for the user to use.
[0022] In one aspect of the embodiment, the water discharge control system has a length of the water discharge hose stored within the water discharge pipe that allows it to move in the extension direction.
[0023] According to one aspect of the embodiment, the water discharge control system allows the water discharge portion to be extended, allowing the user to move the water discharge port to a desired position. Therefore, the water discharge control system can perform control related to stopping and stopping water discharge in a user-friendly manner.
[0024] In the water discharge control system according to one aspect of the embodiment, the water discharge hose is flexible.
[0025] According to one aspect of the embodiment, the water discharge control system allows the water discharge portion to be extended, allowing the user to move the water discharge port to a desired position. Therefore, the water discharge control system can perform control related to stopping and stopping water discharge in a user-friendly manner.
[0026] In the water discharge control system according to one aspect of the embodiment, the detection unit is provided in the water discharge pipe.
[0027] According to one aspect of the embodiment, the water discharge control system has a detection unit such as a sensor mounted on a fixed portion of the water discharge pipe, so that the detection unit does not move even when the water discharge outlet member is removed. This prevents the wiring from becoming complicated and reduces the possibility of deterioration due to the detection unit moving. Therefore, the water discharge control system can execute control related to water discharge stoppage that is user-friendly. [Effects of the Invention]

[0030] 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.
[0031] <1. Embodiment> First, a water discharge control system 1 according to an embodiment will be described below. In order 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 images, 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 elements that make up a kitchen such as a stove, sink, or water discharge unit. 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.
[0032] <1-1. Water discharge control system configuration> The configuration of a water discharge control system 1 according to an embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a schematic perspective view of a water discharge control system according to an embodiment. Fig. 2 is a diagram showing an example of the configuration of a water discharge control system according to an embodiment.
[0033] 1 and 2, the water discharge control system 1 has a kitchen main body 2, an imaging unit 10, a control unit 100, a manual water discharge switching unit 33, a manual water discharge operating unit 331, and an automatic water discharge switching unit 90. The kitchen main body 2 is the main body of the plumbing equipment. 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.
[0034] 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 the automatic water discharge switching unit 90 and the manual water discharge switching unit 33, etc. For example, the water supply 80 is a water supply tool connected to a water distribution pipe, etc., and is connected to a water valve 101, a water type switching valve 104, and the water heater 81, which will be described later. The water heater 81 is a device for heating raw water (also simply referred to as "water") supplied from the water supply 80 into hot water (also simply referred to as "hot water" or "hot water"), and is connected to a hot water valve 102, which will be described later. For example, the water heater 81 may have its hot water temperature controlled by the control unit 100.
[0035] The configuration shown in FIG. 2 is merely an example, and any configuration can be adopted as long as water can be discharged in the desired water discharge mode. For example, in FIG. 2, the solid line connections between each component indicate the communication (transmission and reception) of signals (information) and control relationships between the components, and the dotted line connections between each component indicate an example of the relationship of water flow (flow path). When describing the flow paths W from the water supply 80 to the water outlet 321 separately, they will be described as flow paths W1 to W21, etc., with reference numerals W1 to W21 in FIG. 2, but when describing without any particular distinction, they will be collectively referred to as the flow path W. Furthermore, the control relationship and flow path relationship shown in FIG. 2 are merely an example, and are not limited to the relationship shown in FIG. 2, and any relationship can be adopted. Below, the flow path W from the water supply 80 to the water outlet 321 will be described with the water supply 80 side as the upstream side and the water outlet 321 side as the downstream side.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] The water discharge unit 30 has a water discharge port 321 provided at the tip of a water discharge port member 32, which is a member provided at the end of a water discharge pipe 31, and discharges (spouts) water from the water discharge port 321. The water discharge unit 30 comprises the water discharge pipe 31 extending from the base end side toward the tip side, and the water discharge port member 32 which is detachably held at the tip side of the water discharge pipe 31 and has the water discharge port 321.
[0042] As shown in Figure 3, the water discharger 30 may be provided with a water discharge hose 34 inside the water discharge pipe 31 that can move in the extension direction of the water discharge pipe 31. Figure 3 is a diagram showing an example of the configuration of the water discharger. Figure 3 shows the state of the water discharger 30 when the water discharge hose 34 is stretched (pulled out) by holding (gripping) the water discharge outlet member 32 in the hand. In this way, the water discharger 30 may be a faucet (pull-out faucet) that can be used by stretching the part having the water discharge outlet 321 (the water discharge outlet member 32 in Figure 3).
[0043] As shown in Figure 3, water discharge unit 30 has water discharge port member 32 that is detachable from water discharge pipe 31, and water discharge hose 34 enables water to be discharged even at a position away from water discharge pipe 31. Note that water discharge hose 34 shown in Figure 3 is merely one example, and water discharge hose 34 can be positioned in any desired manner as long as the desired water discharge is possible.
[0044] The water discharge hose 34 has a length that allows it to move to a position where the water spout member 32 is separated from the water discharge pipe 31. The water discharge hose 34 is stored within the water discharge pipe 31 for a length that allows it to move in the extension direction. For example, any part of the water discharge hose 34 other than the part that is located within the water discharge unit 30 may be placed in a storage section of the kitchen main body 2 (for example, a cabinet below the sink 40). In this way, the excess part of the water discharge hose 34 may be stored in any location of the kitchen main body 2. The water discharge hose 34 may be placed in a location corresponding to the flow path W that flows through the water discharge unit 30 in FIG. 2. The water discharge hose 34 may also extend outside the water discharge pipe 31. For example, the water discharge hose 34 may be placed in a location corresponding to the flow path W6 from the automatic water discharge switching unit 90 to the water discharge port 321 in FIG. 2.
[0045] The water discharge hose 34 may also be elastic. In this case, an elastic material may be used for the water discharge hose 34. For example, an elastic material such as rubber may be used for the water discharge hose 34. In this way, the water discharge hose 34 itself may be made of an elastic material. Note that the above is only one example, and any configuration may be adopted as long as the water discharge unit 30 can be stretched. For example, the water discharge hose 34 may have an elastic bellows structure. The water discharge unit 30 may not have the water discharge hose 34. For example, if the water discharge pipe 31 and the water outlet member 32 are formed integrally, the water discharge unit 30 may not have the water discharge hose 34.
[0046] For example, water discharger 30 may be capable of discharging 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 and shower discharge of 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] 2, the water discharge state of water discharger 30 is controlled in accordance with control of automatic water discharge switching unit 90 by control unit 100 (also referred to as "automatic control") and control of manual water discharge switching unit 33 by manual operation by the user (also referred to as "manual control"). In this way, the water discharge state of water discharger 30 is controlled by automatic control by automatic water discharge switching unit 90 (automatic water discharge control) and manual control by manual water discharge switching unit 33 (manual water discharge control). Note that automatic control by automatic water discharge switching unit 90 and manual control by manual water discharge switching unit 33 may be performed in combination, which will be described later.
[0048] The automatic water discharge switching unit 90 has the function of executing automatic control. The manual water discharge switching unit 33 executes automatic control regarding stopping and starting water discharge in response to a control signal from the control unit 100. The automatic water discharge switching unit 90 switches the water discharge state based on the control signal.
[0049] 2, the automatic water discharge switching unit 90 includes a cold water valve 101, a hot water valve 102, a flow rate adjustment valve 103, and a water type switching valve 104. Note that the automatic water discharge switching unit 90 does not necessarily have to include at least one of the cold water valve 101 and the hot water valve 102, but a configuration example in this regard will be described later.
[0050] The water valve 101 is a valve for controlling the flow of raw water (water) supplied from the water supply 80. In FIG. 2, the water valve 101 is connected to a flow path W1 emerging from the water supply 80, and adjusts the flow of water flowing in from the flow path W1 and releases it into a flow path W11. The water valve 101 is provided on a water passage. In FIG. 2, the water valve 101 is provided on a water passage that is a flow path W including the flow from the flow path W1 to the flow path W11. For example, the flow path W including the flow from the flow path W1 to the flow path W11 is a water passage to which water is supplied from the water supply 80, which is a water supply source.
[0051] For example, the water valve 101 functions as a valve for controlling the flow of water supplied from the water supply 80 to the manual water discharge switching unit 33. For example, the water valve 101 may be a solenoid valve that opens and closes in response to a control signal from the control unit 100. Alternatively, the water valve 101 may be a control valve (such as a valve) that can be adjusted to any valve opening (position), such as 0 to 100%. The water valve 101 does not need to be provided on the water passage from flow path W1 to flow path W11.
[0052] The hot water valve 102 is a valve for controlling the flow of hot water (hot water) supplied from the water heater 81. In FIG. 2, the hot water valve 102 is connected to a flow path W2 coming out of the water heater 81, and adjusts the flow of hot water flowing in from the flow path W2 and releases it to a flow path W21. The hot water valve 102 is provided on a hot water path. In FIG. 2, the hot water valve 102 is provided on a hot water path that is a flow path W that includes the flow from the flow path W2 to the flow path W21. The flow path W that includes the flow from the flow path W2 to the flow path W21 is a hot water path through which hot water is supplied from the water heater 81, which is a hot water supply source.
[0053] For example, the hot water valve 102 functions as a valve for controlling the flow of hot water supplied from the water heater 81 to the manual water discharge switching unit 33. For example, the hot water valve 102 may be a solenoid valve that opens and closes in response to a control signal from the control unit 100. Also, the hot water valve 102 may be a control valve (such as a valve) that can be adjusted to any valve opening (position), such as 0 to 100%. Note that the hot water valve 102 does not need to be provided on the hot water passage from flow path W2 to flow path W21.
[0054] Flow rate adjustment valve 103 is a valve that can adjust the flow rate of water discharged from water discharger 30. For example, flow rate adjustment valve 103 is a control valve (such as a 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. Note that flow rate adjustment valve 103 may be a valve of any configuration as long as it can be adjusted to any valve opening (position), such as 0 to 100%.
[0055] For example, the flow rate adjustment valve 103 is used to adjust the water discharge flow rate, such as the instantaneous water discharge flow rate, of the water discharge unit 30. The water discharge flow rate, such as the instantaneous water discharge flow rate, of the water discharge unit 30 is controlled by a control signal from the control unit 100 that adjusts (specifies) the valve opening degree of the flow rate adjustment valve 103.
[0056] For example, the flow rate adjustment valve 103 is provided outside the water discharge pipe 31. The flow rate adjustment valve 103 is provided downstream of the manual water discharge switching unit 33. In FIG. 2, the flow rate adjustment valve 103 is connected to the flow path W3 that comes out from the manual water discharge switching unit 33, and adjusts the flow rate of cold water or hot water (sometimes collectively referred to as "hot water") flowing in from the flow path W3 and discharges it into the flow path W4.
[0057] The water type switching valve 104 is a valve for controlling the flow of a predetermined type of water (also referred to as "specified type water"), such as purified water or functional water, which is water that has been treated by adding water from the water supply 80. The conversion (processing) of water from water to the specified type of water may be performed by the water type switching valve 104 or by another component (a "water type conversion device"). In the following, purified water will be described as an example of specified type water. When the specified type of water is purified water, the water type switching valve 104 functions as a valve for controlling the flow of purified water. In this case, the water type switching valve 104 may convert water to purified water (such as by removing impurities), or a water type conversion device (such as the water purifier 82 in FIG. 11) installed at a location corresponding to the water type switching valve 104 may convert water to purified water (such as by removing impurities).
[0058] In Figure 2, the water type switching valve 104 is connected to flow path W1 coming from the water supply 80, and regulates the flow of the specific type of water converted from water and releases it into flow path W5. The water type switching valve 104 is installed on a water passage. In Figure 2, the water type switching valve 104 is installed on a water passage that is flow path W including the flow from flow path W1 to flow path W5. In this way, the water type switching valve 104 is installed downstream of the water supply 80, which is the water supply source, and on a water passage that branches off from the upstream side of the manual water discharge switcher 33.
[0059] For example, the water type switching valve 104 functions as a valve for controlling the flow of water supplied from the water supply 80 to the manual water discharge switching unit 33. For example, the water type switching valve 104 may be a solenoid valve that opens and closes in response to a control signal from the control unit 100. Furthermore, the water type switching valve 104 may be a control valve (such as a valve) that can be adjusted to any valve opening (position), such as from 0 to 100%. Note that if the water discharge control system 1 does not discharge a specific type of water, the automatic water discharge switching unit 90 does not need to have the water type switching valve 104.
[0060] Flow path W5 from the water type switching valve 104 merges downstream with flow path W4 from the flow rate adjustment valve 103. In this way, the flow path from the water type switching valve 104 merges with the flow path from the manual water discharge switching unit 33 downstream of the manual water discharge switching unit 33. In addition, flow path W6, where flow paths W5 and W4 merge, connects to the water discharge port 321.
[0061] The manual water discharge switching unit 33 has a function of executing manual control. The manual water discharge switching unit 33 executes manual control regarding stopping water discharge in response to operation of the manual water discharge operating unit 331 by the user. The manual water discharge switching unit 33 adjusts the water discharge state based on the user's manual operation of the manual water discharge operating unit 331. For example, the manual water discharge switching unit 33 switches the water discharge state based on the user's manual operation of the manual water discharge operating unit 331.
[0062] The manual water discharge switching unit 33 adjusts the water discharge mode based on the user's manual operation of the manual water discharge operating unit 331. For example, the manual water discharge switching unit 33 adjusts the water discharge flow rate based on the user's manual operation of the manual water discharge operating unit 331. For example, the manual water discharge switching unit 33 adjusts the temperature of the discharged water (water temperature) based on the user's manual operation of the manual water discharge operating unit 331. For example, the manual water discharge switching unit 33 adjusts the water discharge mode based on the user's manual operation of the manual water discharge operating unit 331.
[0063] 1 and 2, the manual water discharge operation unit 331 is a lever handle that accepts manual operation by the user. Note that the lever handle is merely an example, and the manual water discharge operation unit 331 is not limited to a lever handle and can have any configuration as long as it can accept manual operation by the user.
[0064] The manual water discharge operation unit 331 can be manually operated to control the water discharge state from the water discharge unit 30. For example, the manual water discharge operation unit 331 accepts manual operation by the user to adjust the water discharge flow rate. The manual water discharge operation unit 331 also accepts manual operation by the user to adjust the temperature of the discharged water (water temperature). The manual water discharge operation unit 331 also accepts manual operation by the user to adjust the water discharge pattern. Note that the manual operation of the manual water discharge operation unit 331 to adjust the flow rate, water temperature, water discharge pattern, etc. by the user is the same as conventional manual operation, so detailed explanation will be omitted.
[0065] Furthermore, the configuration for adjusting the water discharge mode (also referred to as the "manual water discharge mode switching unit") may be provided separately from the manual water discharge operation unit 331. In this case, for example, the manual water discharge mode switching unit may be provided in the water discharge outlet member 32. Furthermore, the user's manual operation for adjusting the water discharge mode may be accepted by a configuration other than the manual water discharge operation unit 331, and for example, the configuration for accepting the user's manual operation for adjusting the water discharge mode (also referred to as the "water discharge mode operation unit") may be provided in the water discharge outlet member 32. For example, the manual water discharge mode switching unit adjusts the water discharge mode based on the user's manual operation of the water discharge mode operation unit.
[0066] The manual water discharge switching unit 33 can switch the water discharge state from the water discharge unit 30 regardless of the control signal generated by the control unit 100 when controlled by the control signal. The manual water discharge switching unit 33 is connected to the hot water passage and the water passage, and has the function of mixing the hot water and water supplied through the hot water passage and the water passage. For example, the manual water discharge switching unit 33 has a hot water and water mixing valve that mixes the hot water and water. The hot water and water mixing valve is, for example, a control valve that can continuously change the valve opening, and functions as a valve for adjusting the mixing ratio of the hot water and water flowing downstream from the manual water discharge switching unit 33. The hot water and water mixing valve may also have the function of adjusting the flow rate of the hot water and water flowing downstream from the manual water discharge switching unit 33.
[0067] In FIG. 2, the manual water discharge switching unit 33 (such as a hot and cold water mixing valve) is connected to a flow path W11 through which water is supplied and an inflow W21 through which hot water is supplied, and adjusts the mixing ratio of the water flowing in from flow path W11 and the hot water flowing in from flow path W21 before discharging it into flow path W3. The manual water discharge switching unit 33 adjusts the mixing ratio (temperature) of the water and hot water discharged into flow path W3 based on the user's manual operation of the manual water discharge operating unit 331. The manual water discharge switching unit 33 may also adjust the flow rate of the hot and cold water discharged into flow path W3 based on the user's manual operation of the manual water discharge operating unit 331.
[0068] The control unit 100 is a control device that controls water discharge (automatic water discharge). The control unit 100 controls water discharge by controlling the automatic water discharge switching unit 90 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 water from an image captured by the imaging unit 10, and controls the automatic water discharge switching unit 90 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 control water discharge using sensor information detected by any sensor, not limited to the imaging unit 10.
[0069] For example, the control unit 100 controls the type of water discharge by controlling the automatic water discharge switching unit 90 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 (also simply referred to as "flow rate") such as the instantaneous water discharge flow rate by controlling the flow rate adjustment valve 103 based on information detected by each sensor such as the imaging unit 10.
[0070] The control settings of the control unit 100 for the automatic water discharge switching unit 90 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 ingredients or to change the water discharged to 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).
[0071] For example, the control unit 100 is connected to the automatic water discharge switching unit 90. The control unit 100 controls the cold water valve 101, the hot water valve 102, the flow rate adjustment valve 103, and the water type switching valve 104 using control signals sent to the automatic water discharge switching unit 90.
[0072] For example, the control unit 100 controls the flow of water downstream from the cold water valve 101 using a control signal that instructs the opening and closing of the cold water valve 101. For example, the control unit 100 controls the flow of hot water downstream from the hot water valve 102 using a control signal that instructs the opening and closing of the hot water valve 102. For example, the control unit 100 controls the flow of hot water and cold water (flow rate, etc.) downstream from the flow rate adjustment valve 103 using a control signal that instructs the opening and closing of the flow rate adjustment valve 103. For example, the control unit 100 controls the flow of a specific type of water downstream from the water type switching valve 104 using a control signal that instructs the opening and closing of the water type switching valve 104.
[0073] 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.
[0074] 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).
[0075] The control unit 100 may be configured and arranged in any manner as long as it is capable of controlling the automatic water discharge switching unit 90, communicating with each sensor such as the imaging unit 10, and performing processing. 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 the kitchen main body 2. Details of the control unit 100 will be described later.
[0076] The imaging unit 10 is a detection unit that detects at least the water discharge area. For example, the imaging unit 10 is an imaging means that captures an image of a wet space or the like. Note that the imaging unit 10 is merely one example of a detection unit, and any configuration can be employed, such as a distance image sensor using an infrared sensor, as long as the detection target is the water discharge area and the sensor is capable of detecting information used by the control unit 100 to control the wet equipment.
[0077] 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 images 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 images of the bathroom space around the water discharge unit 30. For example, the imaging unit 10 captures images of the bathroom space including the sink 40, etc.
[0078] The imaging unit 10 is disposed in a position where it can capture an image of a desired range (area). The imaging unit 10 is provided above the water discharger 30. 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. For example, the imaging unit 10 may be provided in the water discharger 30. In this case, the imaging unit 10 may be provided in the water discharge pipe 31.
[0079] 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.
[0080] 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.
[0081] 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.
[0082] 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.
[0083] 1 and 2 is merely an example, and the water discharge control system 1 can have any configuration. 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 the imaging unit 10 not included in the water discharge control system 1 and control the water discharge using an image received (acquired) from the imaging unit 10.
[0084] 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.
[0085] 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.
[0086] <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 RAM or the like as a working area. The control unit 100 may be, for example, a microcomputer equipped with any processor such as a CPU. 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).
[0087] The control unit 100 determines the state of the object to be discharged detected by the imaging unit 10. Based on the determination result, the control unit 100 generates a control signal for controlling the state of water discharge from the water discharge unit 30. The control unit 100 automatically controls at least the flow rate based on the determination result.
[0088] 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.
[0089] 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.
[0090] The switching adjustment unit 110 controls the automatic water discharge switching unit 90 by sending a control signal to the automatic water discharge switching unit 90. For example, the switching adjustment unit 110 controls the opening and closing of the cold water valve 101, the hot water valve 102, the flow rate adjustment valve 103, and the water type switching valve 104 in response to instructions from the processing unit 120. The switching adjustment unit 110 sends control signals to the cold water valve 101, the hot water valve 102, the flow rate adjustment valve 103, and the water type switching valve 104, and controls the water discharge state of the water discharged from the water discharger 30 by adjusting the opening and closing of the cold water valve 101, the hot water valve 102, the flow rate adjustment valve 103, and the water type switching valve 104.
[0091] For example, switching adjustment unit 110 adjusts the valve opening of flow rate adjustment valve 103 in response to instructions from processing unit 120. Switching adjustment unit 110 sends a control signal to flow rate adjustment valve 103 and adjusts (sets) the valve opening of flow rate adjustment valve 103, thereby adjusting the water discharge flow rate, such as the instantaneous water discharge flow rate, of water discharge unit 30.
[0092] 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. The processing unit 120 determines the state of the object to be discharged detected by the imaging unit 10. For example, the processing unit 120 determines the state of the object to be imaged detected from the image captured by the imaging unit 10. The processing unit 120 functions as an operation detection unit that detects user operations.
[0093] 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).
[0094] 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.
[0095] 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.
[0096] The processing unit 120 may use the sensor information to determine whether or not to discharge water, and if so, select a water discharge state based on the contents stored in the memory unit 130. In this case, the processing unit 120 generates a control signal that instructs the device to stop discharging water in the water discharge state corresponding to the selected water discharge state. The processing unit 120 uses the generated control signal to instruct the switching adjustment unit 110 to control (change) the state of at least one of the cold water valve 101, the hot water valve 102, the flow rate adjustment valve 103, and the water type switching valve 104.
[0097] For example, 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 103 based on the determined instantaneous water discharge flow rate. The processing unit 120 generates a control signal that instructs 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 103.
[0098] The processing unit 120 determines the object to be discharged water from the image captured by the imaging unit 10. The processing unit 120 can determine the user's hand and the implement from the image captured by the imaging unit 10.
[0099] The processing unit 120 functions as an automatic water discharge control unit that controls the water discharge state from the water discharger 30. For example, the water discharge state includes five elements: water discharge stop, flow rate, temperature, type, and water discharge form (also simply referred to as "form"). For example, the water discharge form (form) is the shape of the water discharge, such as shower or straight. Note that the above water discharge state elements are merely examples, and the water discharge state elements may be any elements. For example, the water discharge state may include six or more elements, or four or fewer elements. For example, if the type is an element that also includes the temperature aspect, such as cold water, hot water, or purified water, the water discharge state may include four elements: water discharge stop, flow rate, type, and form, without including the temperature element. The processing unit 120 generates a control signal for controlling the water discharge state from the water discharger 30 based on the determination result. The processing unit 120 causes the switching adjustment unit 110 to send the generated control signal to the automatic water discharge switching unit 90, and causes the automatic water discharge switching unit 90 to execute water discharge control based on the control signal. For example, the processing unit 120 automatically controls at least the flow rate based on the determination result. Note that the processing unit 120 does not necessarily have to control the temperature based on the determination result.
[0100] Processing unit 120 controls switching adjustment unit 110. Processing unit 120 controls the stopping and spouting of water from water discharger 30 by controlling the switching of switching adjustment unit 110. Processing unit 120 controls the stopping and spouting of water from water discharger 30 by controlling switching adjustment unit 110 based on the determination result.
[0101] Processing unit 120 determines the size of the object to be discharged. Processing unit 120 controls the state of water discharge 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 water discharge flow rate as the object to be discharged is larger.
[0102] The processing unit 120 classifies the object to be discharged as either a tool or a human hand, and controls the state of discharge of water 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 state of discharge of water based on the classification result.
[0103] 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 water discharge state 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.
[0104] 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.
[0105] 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.
[0106] 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.
[0107] 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.
[0108] When the shape of the object to be discharged is a predetermined type, the processing unit 120 controls the water discharge state based on the predetermined type. When the size of the object to be discharged is changed while the object is held within the water discharge area, the processing unit 120 does not change the water discharge state.
[0109] Processing unit 120 controls the water discharge state 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.
[0110] 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.
[0111] 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.
[0112] 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.
[0113] 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.
[0114] 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.
[0115] 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.

[0119] 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.
[0120] <1-3. Area example> Before describing specific processes according to the embodiment, an example of a water discharge area will be described using Fig. 4. Fig. 4 is a diagram showing an example of the area. Fig. 4 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. 4 shows an example of a water discharge area WA1.
[0121] In Fig. 4, 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. 4 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.
[0122] <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. 5. Fig. 5 is a diagram showing an example of a process using an image executed by the water discharge control system.
[0123] Image IM1 in FIG. 5 shows an example of a case where an image captured by the imaging unit 10 is the processing target. In FIG. 5, 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. 5, 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.
[0124] 5 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.
[0125] 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.).
[0126] 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. 5, 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.
[0127] 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.
[0128] 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.
[0129] 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.
[0130] 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.
[0131] 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.
[0132] 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.
[0133] 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.
[0134] 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.
[0135] 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.
[0136] 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.
[0137] <1-5. Example of processing by water discharge control system> Based on the above-mentioned content, the processing executed by the water discharge control system 1 will now be described.
[0138] <1-5-1. Example of the relationship between automatic control and manual control> First, an example of the relationship between automatic control and manual control will be described, shown in Fig. 6. Fig. 6 is a diagram showing an example of the relationship between automatic control and manual control.
[0139] As shown in Figure 6, when the water discharge state from water discharger 30 is in the first water discharge state by automatic water discharge switching unit 90, it is changed to the second water discharge state by a first operation on manual water discharge operation unit 331, and further, when the first operation on manual water discharge operation unit 331 is released, it returns to the first water discharge state. For example, water discharge control system 1 accepts as the first operation a user operation that changes the state (position, direction, tilt, etc.) of manual water discharge operation unit 331, which is a lever handle. In this case, releasing the first operation means returning the state of manual water discharge operation unit 331, which is a lever handle, to the state before the first operation (original state).
[0140] For example, when the user performs an operation (first operation) to instruct the manual water discharge operation unit 331 to stop water while the water discharge unit 30 is discharging water (first water discharge state) due to automatic control by the automatic water discharge switching unit 90, the water discharge control system 1 changes the water discharge state to a state in which the water discharge unit 30 has stopped water (second water discharge state). Then, for example, when the user cancels the operation (first operation) to instruct the manual water discharge operation unit 331 to stop water, the water discharge control system 1 changes (returns) the water discharge state from a state in which the water discharge unit 30 has stopped water (second water discharge state) to a state in which the water discharge unit 30 is discharging water (first water discharge state).
[0141] Furthermore, for example, when the user performs an operation (first operation) on the manual water discharge operation unit 331 to lower the hot water temperature while the water discharge unit 30 is discharging hot water at a first temperature (e.g., 50°C) under automatic control by the automatic water discharge switching unit 90 (first water discharge state), the water discharge control system 1 changes the water discharge state to a state in which the temperature of the hot water from the water discharge unit 30 is lowered to a second temperature (e.g., 40°C) (second water discharge state). Then, for example, when the user cancels the operation (first operation) on the manual water discharge operation unit 331 to lower the hot water temperature, the water discharge control system 1 changes (returns) the water discharge state from a state in which the water discharge unit 30 discharges hot water at the second temperature (second water discharge state) to a state in which the water discharge unit 30 discharges hot water at the first temperature (first water discharge state).
[0142] Furthermore, for example, when the user performs an operation (first operation) on the manual water discharge operating unit 331 to reduce the flow rate while the water discharge unit 30 is discharging hot and cold water at a first flow rate due to automatic control by the automatic water discharge switching unit 90 (first water discharge state), the water discharge control system 1 changes the water discharge state to a state in which the flow rate of hot and cold water from the water discharge unit 30 is reduced to a second flow rate (second water discharge state). Then, for example, when the user cancels the operation (first operation) on the manual water discharge operating unit 331 to reduce the flow rate of hot and cold water, the water discharge control system 1 changes (returns) the water discharge state from a state in which the water discharge unit 30 discharges hot and cold water at the second flow rate (second water discharge state) to a state in which the water discharge unit 30 discharges hot and cold water at the first flow rate (first water discharge state).
[0143] In this way, when control is performed by both the automatic water discharge switching unit 90 and the manual water discharge operation unit 331, the water discharge control system 1 controls water discharge and stopping by reflecting the contents of both controls. When automatic control by the automatic water discharge switching unit 90 and manual control by the manual water discharge switching unit 33 are performed simultaneously, the water discharge control system 1 controls the water discharge state of the water discharge unit 30 based on both the automatic control and the manual control. As a result, even if the automatic control by the automatic water discharge switching unit 90 is not the state desired by the user, the water discharge control system 1 can control the water discharge state to the user's desired state by reflecting the manual control based on the user's manual operation in the water discharge state of that automatic control.
[0144] The first water discharge state, second water discharge state, and first operation described above are merely examples, and the water discharge control system 1 may accept any user operation as the first operation, and may change from any first water discharge state to any second water discharge state in response to any first operation. For example, the water discharge control system 1 shown in Fig. 2 can control the flow rate and hot and cold water through automatic control by the automatic water discharge switching unit 90, and can control the flow rate and hot and cold water through manual control by the manual water discharge switching unit 33. For example, the water discharge control system 1 controls hot and cold water by changing the opening of the cold water valve 101 and the hot water valve 102 (hot and cold water valves).
[0145] <1-5-2. Example of automatic control of water discharge control system> Next, the following first to third processes will be described as examples of automatic control 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, although the following description will be made with the water discharge control system 1 as the processing subject, 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. Furthermore, as described above, if manual control is performed during automatic control by the first to third processes, the water discharge control system 1 controls the water discharge state to reflect both the automatic control by the first to third processes and the manual control.
[0146] <1-5-2-1. First processing flow> First, the flow of processing related to the first processing will be explained using Fig. 7. Fig. 7 is a flowchart showing an example of the procedure related to the first processing executed by the water discharge control system. For example, Fig. 7 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. 7, 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.
[0147] 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. 5, and detailed description thereof will be omitted.
[0148] 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.
[0149] 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.
[0150] 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. 7, and the water discharge control system 1 may execute the processing of step S104 at any timing before determining the flow rate.
[0151] 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.
[0152] 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.
[0153] 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.
[0154] 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.
[0155] 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.
[0156] 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.
[0157] 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.
[0158] 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.
[0159] 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.
[0160] 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.
[0161] 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.
[0162] 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.
[0163] <1-5-2-2. Second processing flow> It should be noted that the process shown in FIG. 7 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. 8. FIG. 8 is a flowchart showing an example of the procedure related to the second process executed by the water discharge control system. For example, FIG. 8 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. 7 will be omitted as appropriate.
[0164] 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).
[0165] 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.
[0166] 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 pattern (step S204). Note that the execution timing of step S204 is not limited to the timing shown in Fig. 8, and the water discharge control system 1 may execute the processing of step S204 at any timing before determining the flow rate.
[0167] 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.
[0168] 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.
[0169] 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.
[0170] 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.
[0171] 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.
[0172] 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).
[0173] 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.
[0174] 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.
[0175] <1-5-2-3. 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 processing related to the third processing will be explained using FIG. 9. FIG. 9 is a flowchart showing an example of the procedure related to the third processing executed by the water discharge control system. Note that explanations of points similar to those explained in FIG. 7 and FIG. 8 will be omitted as appropriate.
[0176] 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).
[0177] 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.
[0178] 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. 7, and the water discharge control system 1 may execute the processing of step S304 at any timing before determining the flow rate.
[0179] 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.
[0180] 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.
[0181] 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.
[0182] 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.
[0183] 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.
[0184] 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.
[0185] 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.
[0186] 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.
[0187] 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.
[0188] 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.
[0189] 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.
[0190] <1-7. Other configuration examples> 2 is merely an example, and any device configuration can be adopted for the water discharge control system 1. The water discharge control system 1 can be applied to various configurations as long as it can execute at least a part of the above-mentioned processes.
[0191] As described above, the water discharge control system 1 does not have to have at least one of the cold water valve 101 and the hot water valve 102. For example, the water discharge control system 1 does not have to have the cold water valve 101 and the hot water valve 102, as shown in FIG. 10. FIG. 10 is a diagram showing an example of another configuration of the water discharge control system. In this case, water from the water supply 80 and hot water from the water heater 81 flow directly into the manual water discharge switching unit 33. For example, if the water discharge control system 1 does not have the cold water valve 101 and the hot water valve 102, the flow rate can be controlled by automatic control, and both the flow rate and temperature can be controlled by manual control. Note that other points are the same as those of the water discharge control system 1 shown in FIG. 2, so detailed explanations will be omitted.
[0192] The water discharge control system 1 may also have a configuration as shown in Fig. 11. Fig. 11 is a diagram showing an example of another configuration of the water discharge control system.
[0193] 11 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 FIG. 11, water discharge control system 1 includes water purifier 82 that purifies raw water supplied from water supply 80 via water type switching valve 104. 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.
[0194] In the above-described embodiment, the water discharge control system 1 has been described as being applied to a kitchen, but it can be applied to any wet space where utensils can be used, for example, a wash area in a toilet space or a vanity where water discharge and stopping actions such as hand washing are performed.
