And a spout 80. In addition, in this embodiment, although it demonstrates that raw water is tap water, it is not limited to this, and water other than tap water may be used as raw water.

The control unit 10 is a CPU (Central Processing Unit) that controls the water purifier 100. The control unit 10 includes a first control unit 11, a flow rate acquisition unit 12, a voice recognition unit 13, and a second control unit 14.

The first control unit 11 controls each on-off valve for discharging or stopping the purified water from the water outlet based on the voice of the user acquired by the voice recognition unit 13. Specifically, in the present embodiment, the first controller 11 controls opening/closing of the first opening/closing valve 51. Moreover, the 1st control part 11 specifies the amount of water discharge based on a user's voice, and controls opening/closing of the 3rd on-off valve 52 so that the amount of purified water discharged from the water outlet 80 may become the specified amount of water discharge. To do. The first control unit 11 determines whether the content of the user's voice corresponds to the voice information of the data table 21 stored in the storage unit 20. The first control unit 11 acquires control information associated with the voice information from the data table 21, and controls the water purifier 100 based on the control information.

The flow rate acquisition unit 12 acquires the flow rate of at least one of tap water and purified water from the flow rate sensor 60.

The voice recognition unit 13 acquires the voice of the user from the microphone 31 and performs voice recognition. Hereinafter, the information acquired by the voice recognition from the voice of the user is also referred to as “voice information”. The voice recognition unit 13 may recognize the type of user. For example, information indicating the characteristics of a voice and information such as an ID for identifying an individual are stored in association with each other, and who is the user is recognized from the recognized voice. Further, the control by the voice recognition unit 13, the control by the first control unit, the control by the second control unit, and the like may be changed according to the type of the recognized user. For example, the sensitivity of the microphone may be adjusted according to the user, and the usage situation of the user and the habit of words used by the user for the instruction may be learned. The water purifier 100 may have a clock function and may learn the usage status depending on the time of day. As a result, appropriate control is performed according to the usage situation of a user, such as a child, whose height is short and away from the microphone, or a user who frequently works in the kitchen, etc., so that the user can use it more easily. Further, it is possible to reduce erroneous operations such as erroneous recognition caused by a voice other than the voice of the user such as the TV. It is also possible to limit the users.

When the second control unit 14 receives the voice of the user, the second control unit 14 controls to notify the user of recognizable information in response to the voice. For example, the second control unit 14 refers to the data table 21, acquires the information to be notified to the user, which is associated with the voice information, and causes the speaker 32 to notify the information. The information notified to the user may be light, and the second control unit 14 controls an LED (not shown) that emits light of a predetermined color based on the audio information. Further, the notification information is not limited to voice and LED light, and may be light using another light source, an image, or the like. In the case of an image, the water purifier 100 is preferably provided with a display such as a liquid crystal display or an organic EL display and displayed on the display.

The storage unit 20 is a memory that stores data necessary for the processing executed by the control unit 10. In the storage unit 20, for example, the mode of the control unit 10, the data table 21, the remaining period during which the water purification capacity of the water purification cartridge 40 can be maintained, pace information indicating the frequency of water purification by the water purification cartridge 40, and the water purification cartridge 40. The information and the like indicating the usage history of are stored. In the present embodiment, a form in which the storage unit 20 is included in the water purifier 100 will be described.

The control information includes the mode of the control unit 10, a response language for the second control unit 14 to perform control for notifying the user, and the second control when the voice recognition unit 13 recognizes the same voice information again. There is a response at the time of re-recognition notified by the unit 14, hardware such as an opening/closing valve controlled by the first control unit 11, and control contents of an LED controlled by the second control unit 14. Further, the “hardware” information is associated with information indicating how to control the hardware. For example, "open first opening/closing valve" is control information indicating control for opening the first opening/closing valve.

The microphone 31 converts a user's voice into an electric signal and transmits the electric signal to the voice recognition unit 13. It is preferable that the microphone 31 is disposed above the water outlet 80 from the viewpoint of waterproofness, the viewpoint of preventing pickup of noise of water discharge, and the viewpoint of easily picking up the voice of the user. Further, the microphone 31 may be one that can be carried independently of the other components of the water purifier 100. For example, from the viewpoint that a user (especially a short user such as a child) easily emits a voice toward the microphone 31, and that the user can operate even if the user is away from the spout 80, the microphone 31 is It may be a portable wireless microphone that performs wireless communication. In addition to the microphone 31, the water purifier 100 may include an operation switch for instructing an operation intended by the user. Thus, even when the water purifier 100 is used in a situation or in a state where it is difficult to make a voice, or when the surroundings of the water purifier 100 are loud and the voice recognition unit 13 cannot recognize the content of the voice, the user intends the water purifier 100. The operation to be performed can be instructed.

The speaker 32 outputs the voice information transmitted from the second control unit 14 to the outside as voice.

The purified water cartridge 40 is a device that produces purified water from tap water. The water purification cartridge 40 may be any one as long as it purifies tap water, and may be, for example, a filter medium for filtering impurities in tap water. Examples of the filter medium include activated carbon and hollow fibers.

The first opening/closing valve 51 is an opening/closing valve for discharging or stopping the purified water from the water discharge port 80. The arrangement of the first opening/closing valve 51 is not particularly limited as long as the purified water can be consequently discharged or stopped from the water discharge port 80, and may be upstream or downstream of the water purification cartridge 40. It is preferable that the cartridge 40 is disposed upstream of the water purification cartridge 40 so that static pressure is not applied to the cartridge 40.

The constant flow valve 50 and the third opening/closing valve 52 are opening/closing valves for adjusting the amount of purified water discharged from the water outlet 80. When the constant flow valve 50 is opened, it passes a certain amount of purified water. The third on-off valve 52 is an on-off valve for adjusting the amount of water discharged from the water outlet 80. The third opening/closing valve 52 can change the flow rate of purified water to be passed. The first on-off valve 51 and the third on-off valve 52 are preferably electromagnetic valves, for example.

The flow rate sensor 60 is a sensor that measures the flow rate of at least one of tap water and purified water. In the present embodiment, the flow sensor 60 is a sensor that measures the flow rate of raw water. The flow rate sensor 60 is arranged between the first opening/closing valve 51 and the water purification cartridge 40. That is, the flow rate sensor 60 acquires the flow rate of the tap water passing between the first opening/closing valve 51 and the water purification cartridge 40. In the present embodiment, the flow rate sensor 60 is arranged on the upstream side (front stage) of the water purification cartridge 40 in the water flowing direction, but may be arranged on the downstream side (post stage) of the water purification cartridge 40. That is, the flow rate sensor 60 may obtain the flow rate of raw water or the flow rate of purified water.

The water purifier 100 may or may not include the flow rate sensor 60. When the water purifier 100 includes the flow rate sensor 60, the actual flow rate of raw water or purified water on the flow path can be accurately measured. When the water purifier 100 does not include the flow rate sensor 60, which does not require fine flow rate adjustment, the configuration can be relatively inexpensive and simple.

The tap water tap 70 is a tap for tapping or stopping tap water supplied from a tap water supply passage (not shown).

The water outlet 80 is an opening through which the purified water generated by the water purification cartridge 40 is discharged.

When the voice information is "confirmation" or "usage", the second control unit 14 performs the following control based on the control information specified in step S3. The 2nd control part 14 acquires the integrated production amount of the purified water which the water purification cartridge produced from the flow sensor 60, and based on the said integrated production amount, "~L was used." Let me know. When the flow rate sensor 60 is not provided, the flow rate may be set to, for example, 3 L/min to calculate the integrated generation amount based on the pace information.

Further, when the voice information is "reset", the second control unit 14 performs the following control based on the control information specified in step S3. The second control unit 14 causes the speaker 32 to notify the user by voice, "Reset?". After that, when the voice recognition unit 13 recognizes that the voice information is “yes” within one minute, the second control unit 14 causes the speaker 32 to “reset” by voice notification to the user. And the 1st control part 11 memorize|stores the amount of purified water which the water purification cartridge 40 produced|generated in the period from the time when the voice recognition part 13 recognizes that voice information is "reset" and "yes" to this time. It is stored in the unit 20. When the voice recognition unit 13 recognizes that the voice information is “No”, the second control unit 14 causes the speaker 32 to notify “I will stop” by voice. When the voice recognition unit 13 does not detect the voice input to the microphone 31 within one minute, and the voice recognition unit 13 acquires the voice information within one minute, the voice recognition unit 13 within one minute When the voice information is not recognized as the response language “yes” or “no”, the usage amount reset mode is ended.

Further, even if the voice information is “Good night”, “Thank you”, or “End”, even if the voice recognition unit 13 recognizes that the voice information is in the language (excluding “Hello”) in the data table 21. The control unit 10 does not perform the above control. Then, the second control unit 14 causes the speaker 32 to notify the user by voice, "End." In addition, the second control unit 14 causes the LED to turn off the orange light to notify the user.

(Other operations of the first controller 11 in step S4)
When the voice of the user is an instruction to measure a predetermined amount of purified water, the first control unit 11 sets the purified water discharged from the water outlet 80 to a predetermined amount based on the opening/closing time of the first opening/closing valve 51. Thus, the first on-off valve 51 is controlled.

When the voice of the user is an instruction to measure a predetermined amount of purified water, the first control unit 11 sets the purified water discharged from the water outlet 80 to a predetermined amount based on the flow rate measured by the flow rate sensor 60. Then, the first on-off valve 51 is controlled. Moreover, the 1st control part 11 calculates the estimated time until the amount of purified water spouted from the spout 80 reaches a predetermined amount based on the flow rate. The 1st control part 11 controls the 1st on-off valve 51 so that purified water may be stopped based on prediction time. Further, the first control unit 11 does not perform control based on the predicted time as described above, but controls based on the actual flow rate measured by the flow rate sensor 60 so that the purified water discharged from the discharge port 80 has a predetermined amount. You may. In this case, for example, the first control unit 11 recognizes whether or not a predetermined amount is reached based on the flow rate measured by the flow rate sensor 60, and if so, controls the first opening/closing valve 51. Good. In addition to the method of calculating (measuring) a predetermined flow rate from the measured value of the flow meter (measured flow rate) and controlling the water stoppage, the water discharge amount is displayed by the combination of the notification means (counter) and the flow rate sensor, The user may instruct to stop the water after confirming at the counter that the desired water discharge amount has been reached.

The water purifier 100 may include a sensor that detects the presence or absence of an object at a position that receives the water discharged from the water discharge port 80. Examples of the sensor include an infrared sensor. When the sensor detects the presence of an object, the first control unit 11 controls the first opening/closing valve 51 so that water is discharged from the water discharge port 80.

The first control unit 11 calculates the remaining period during which the water purification cartridge 40 can maintain the water purification capacity based on the integrated generation amount of the water purification generated by the water purification cartridge 40, which is measured by the flow rate sensor 60. The 1st control part 11 calculates the said remaining period regularly (for example, every week, every month, etc.). The first control unit may further calculate the remaining period based on pace information indicating the frequency with which the water purification cartridge has generated water purification.

The first control unit 11 causes the storage unit 20 to store the remaining period calculated and acquired, pace information, information indicating the usage history of the water purification cartridge, and the like. In such a form, the storage unit 20 may be a server connected to the Internet, a cloud server, or the like. By storing it in an external server such as a cloud server, the user can easily manage it with another terminal such as a smart phone.

According to the water purifier 100, for example, in a scene such as a cooking scene in which switching is often performed, such as washing hands with hot water or washing vegetables with purified water, switching can be automatically performed by only voice. Therefore, the operability is improved for the user.

(Other operations of the second controller in step S4)
The second control unit 14 notifies the timing of arrival of the prediction time based on the prediction time calculated by the first control unit 11. The second control unit 14 notifies the user of the remaining period when the remaining period calculated by the first control unit 11 falls below a predetermined period (for example, one month remaining). The 2nd control part 14 may transmit the said remaining period to the separate terminal device which can communicate with a self-water purifier.

In this way, since the water purifier 100 and the control unit 10 operate the on-off valve and the like by the voice of the user, the user can discharge and stop the purified water without using the hand, and maintain hygiene. You can Further, the purified water can be discharged and stopped even when the user's hand is blocked. The user can operate the water purifier 100 as desired by voice.

(Modification)
In this embodiment, when the voice information is “hello”, the control unit 10 specifies that the mode associated with the recognition language “hello” is the voice recognition mode and shifts to the voice recognition mode. However, it is not limited to such a form. For example, the transition to the voice recognition mode may be performed by a motion sensor. That is, the water purifier 100 according to one aspect of the present invention further includes a motion sensor that detects the presence or absence of the user, and the voice recognition unit 13 uses the motion sensor when the motion sensor detects the presence of the user. You may start the mode which acquires a person's voice. The human sensor detects, for example, the presence or absence of a user near the water outlet 80. The range in the vicinity of the water discharge port 80 may be set in advance, and for example, the radius of the water discharge port 80 may be within 1 m or the range in which the user normally exists at the time of use. Since the water purifier 100 includes the motion sensor, it is possible to prevent malfunction and automatically stop the water even if the user forgets to give an instruction to stop the water. Accordingly, it is possible to prevent water from being discharged more than necessary, and thus it is possible to prevent wasteful reduction of the remaining period during which the water purification cartridge 40 can maintain the water purification capacity.

At this time, the first control unit 311 may control the opening/closing of the first opening/closing valves 354, 355, 356 so that the water is temporarily stopped when the predetermined amount is reached. After that, after the second control unit 14 notifies that the water discharge is started, the first control unit 311 may control opening/closing of the first opening/closing valves 354, 355, 356 so as to start the water discharge. Further, even if the second control unit 14 reaches a predetermined amount and informs that the drainage of the purified water generated by the previously used water purification cartridge is completed without the first control unit 311 controlling the water to stop once. Good.

Also when switching from raw water to purified water, the opening/closing of the first opening/closing valves 354, 355, 356 may be controlled so as to drain the water remaining in the pipe.

Further, as another method for solving the above problems, the pipes up to the water outlet 280 may be separated.

When switching the water purification cartridge to another water purification cartridge, not only when switching from raw water to purified water, but also when the water purifier 100 is used, a predetermined amount of raw water or purified water may be drained first. The control performed by the first control unit 311 and the second control unit 14 is the same as the control described above.
