Description

The present invention provides a guide unit for easily performing an operation on a sensor unit that is operated to discharge flush water in a system kitchen, and the guide unit determines an operation state of the system kitchen by a user. The present invention relates to a system kitchen provided with a notification function for notifying the user.

Conventionally, there has been a system kitchen that opens and closes a valve by inserting an object to be detected in a detection range of a sensor unit that transmits an open / close signal to the valve and discharges water from the faucet.

In addition, a kitchen device is described in which an object to be cleaned (for example, a hand or tableware) is brought close to the faucet and detected by a photoelectric sensor to open a valve (see, for example, Patent Document 1). ).

In addition, an automatic faucet device is disclosed in which an object to be detected is an automatic faucet device intended for tableware or a hand, and two or more transmitting elements are alternately driven to expand a detection area and detect a wide range. (For example, refer to Patent Document 2).
Japanese Utility Model Sho 61-075570 JP 2003-213748 A

However, as in Patent Document 1, when a hand is put out with respect to the photoelectric sensor arranged on the sink side wall, it is unclear to which place the photosensor may be put out with respect to the detection range existing in the sink internal space. However, depending on the position where the object to be detected is put out, it is outside the detection region, so that there is a possibility that water is not discharged. Also, since the photoelectric sensor does not have a function of detecting the hand and notifying the user that the valve is open, the user does not intuitively recognize the timing when the sensor detects the user's hand. There was a possibility.

In addition, as in Patent Document 2, even when the detection area is enlarged using a plurality of transmitting elements, it is difficult to recognize the place of insertion in the space. Since it is outside the detection region, there is a possibility that a problem that water is not discharged occurs.

Therefore, in the present invention, in the system kitchen, a guidance unit that guides the detected object to the sensor unit is provided, and the detected object is reliably detected by causing the detected object to enter the detection area of the sensor unit. Since the guidance unit has a notification function for notifying the user of the operating state of the system kitchen, the user can intuitively recognize that the sensor unit has detected the hand that the user has extended. The purpose is to provide a system kitchen.

In order to achieve the above object, according to one aspect of the present invention, a faucet having a water outlet, a sink that receives water discharged from the water outlet, a sensor unit that transmits and receives radio waves, and A valve that opens and closes based on detection information of the detected object obtained from the sensor unit and switches whether or not to supply water to the water outlet, and a guide unit that prompts the user to operate the sensor unit The sensor part is provided on the back side of the sink side wall, and the guide part is arranged such that the center position of the guide part is located on the rear edge side of the sink with respect to the center position of the sensor part. It is possible to provide a system kitchen characterized in that it is arranged on the upper surface of the counter adjacent to the sink, and the guide section has a notification function for notifying a user of the operation state of the system kitchen.

Moreover, according to one aspect of the present invention, the faucet having a water outlet, a sink that receives water discharged from the water outlet, a sensor unit that transmits and receives radio waves, and the radio wave sensor are obtained. A system kitchen having a valve that opens and closes based on detection information of a body to be detected, and switches whether or not to supply water to the water outlet, and a guidance unit that prompts a user to operate the sensor unit. The sensor part is provided on the back side of the sink side wall, and the guide part is positioned such that the center position of the guide part is located on the system kitchen rear edge side with respect to the center position of the sensor part.
The system kitchen may be provided, which is disposed on a sink side wall provided with the sensor unit, and the guide unit has a notification function of notifying a user of an operation state of the system kitchen.

In addition, according to one aspect of the present invention, it is possible to provide a system kitchen characterized in that the radio wave sensor is disposed on a sink side wall adjacent to the counter.

Further, according to one aspect of the present invention, the guiding portion is installed on both the sink side wall and the counter upper surface, and the guiding portion provided on the sink side wall is a system than the guiding means provided on the counter upper surface. It is possible to provide a system kitchen characterized by being arranged on the kitchen rear edge side.

Further, according to one aspect of the present invention, the guide portion includes at least a light emitter such as an LED,
The light emitting body can provide a system kitchen characterized in that a display form changes according to an open / closed state of the bulb.

According to another aspect of the present invention, the induction unit includes at least a sound output device such as a speaker, and the sound output device changes an output form when the valve is opened. Can be provided.

  According to the present invention, when the sensor portion is provided on the sink side wall, for example, the position of the sensor cannot be grasped during the operation in front of the counter, and it is unclear as to where the object to be detected can be inserted. However, by arranging the guiding part on the counter upper surface, it is possible to insert the detected object into the sensor part on the sink side wall even in the situation where the sensor part on the sink side wall cannot be seen. The location becomes clear and the detection accuracy can be improved. In addition, since the guidance unit has a notification function for notifying the user of the state of the system kitchen, the user can intuitively recognize the state in which the sensor unit has detected the detected object.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a schematic configuration diagram of the system kitchen of the present invention. The system kitchen of the present invention includes a faucet 1 having a water outlet, a sink 2 that receives water discharged from the water outlet, a sensor unit 6 that transmits and receives radio waves, and a detected object obtained from the sensor unit. A system kitchen having a valve 4 that opens and closes based on the detected information and switches whether or not to supply water to the water outlet, and a guidance unit 7 that prompts the user to operate the sensor unit. The portion 6 is provided on the back side of the sink side wall 3, and the guide portion 7 is an upper surface of the counter adjacent to the sink 2 so that the center position of the guide portion 7 is located on the rear edge side of the sink 2 with respect to the center position of the sensor portion 6. 8 is arranged. Furthermore, the guidance | induction part 8 is the structure provided with the alerting | reporting function which alert | reports the operating state of a system kitchen to a user.

First, the direction relationship of the sink 2 in the present embodiment will be described. In FIG. 1, the place where the user uses the sink 2, for example, in this embodiment, the surface facing the faucet 1 is the front edge side, the surface facing the front edge side is the rear edge side, and the sink opening surface direction is The upper direction, the direction in which the sink bottom surface exists, is the lower side, the left side of the drawing is the left side, and the right side of the drawing is the right side. A sink is comprised by the side wall and bottom face which exist in the front edge side, the rear edge side, the left side, and the right side. Note that the boundary between the sink side wall 3 and the bottom surface provided in each direction is not necessarily clear. For example, the connection surface between the side surfaces may be formed as a curved surface. Further, the sink bottom surface and the sink sidewall may be formed at an identifiable angle or shape. Further, the bottom surface of the sink is not limited to a horizontal surface, and may be formed with an inclination. Further, the sink sidewalls may all change in the same depth direction according to the shape of the sink bottom surface and the entire sink without having the same length. Here, the sink 2 becomes a recess with respect to the counter upper surface 8 as shown in FIG. 1 and receives water discharged from the water outlet. Therefore, in FIG. 1, the faucet 1 is disposed on the counter upper surface 8, and a portion having a concave shape in the vertical direction relative to the counter upper surface 8 is referred to as a sink 2.

The sensor unit 6 is shown in detail in FIG. The sensor unit 6 transmits a transmission signal 9 to the outside.
And receives the reception signal 10 from the detected object, and the detection signal 11 based on the reception signal 10
The detection unit 12 that generates the detection signal 11, the signal processing unit 14 that generates the determination signal 13 by amplifying the detection signal 11 from the detection unit 12 or performing frequency separation using a filter or the like, and the determination signal output from the signal processing unit 14 13 includes a control unit 15 that transmits an open / close signal 5 to the valve 4. In this embodiment, the signal processing unit 14 is provided for reducing the influence of noise and the like and improving the accuracy of the determination signal for the information obtained from the detection signal 11, but the circuit can be simplified and miniaturized. It is also possible to remove the signal processing circuit 14 to achieve this. In this case, the detection signal 11 is input as the determination signal 13 by the control unit 15 and the opening / closing control of the valve 4 is performed.

Next, the installation location of the sensor unit 6 will be described. The sensor unit 6 is not provided on the counter upper surface 8 adjacent to the sink 2 but on the sink side wall 3. This is because the counter top surface 8 is
In order to place cooking work in the kitchen, cooking utensils, food ingredients, and the like, the sensor unit 6 determines the operation during cooking work and the presence / absence of cooking utensils, which may cause false detection. Further, in order to prevent erroneous detection, the user cannot use the periphery of the sensor unit 6 and the cooking work in the kitchen is restricted, so that the usability is deteriorated. In addition, when the sensor unit 6 is installed on the bottom surface of the sink inside the sink 2, it is possible to detect the presence or absence of an object with the sensor unit 6 by placing a cooking utensil or food inside the sink 2.
The movement of the object near the bottom of the sink generated by the washing operation in the sink 2 and the movement of the washing water may be detected, which may cause a false detection. Further, in the conventional method of transmitting the transmission signal 9 from the sensor unit 6 to the space and creating an invisible detection area that can be created in the space, the detection area is unclear, so that it enters the detection area during the cooking operation. In addition, there is a high possibility of false detection without being able to enter the detection area during use. Therefore, in the present invention, the sensor portion 6 is provided on the sink side wall 3. Since the sink side wall 3 hardly performs work on the side wall, it is extremely unlikely that problems such as place restrictions in cooking operations in the kitchen will occur. Further, since it is extremely unlikely that an object is always in contact with or installed on the sink side wall 3, it is possible to reduce erroneous detection due to the presence or absence of an object.

However, when the sensor unit 6 is installed on the sink side wall 3, an object such as a cooking utensil placed inside the sink 2 approaches, or the flow line of the hand performing the cooking operation passes near the sensor unit 6. There is a possibility. Therefore, as a method for detecting an object in the sensor unit 6, it is desirable that the vicinity of the sensor unit 6 be a detection range. This is because when the object is placed in the vicinity of the sink side wall 3, the sink side wall 3 shields at least one of the spaces, so that a hand hits the side wall when performing an operation such as placing / taking an object occurs. To do. In addition, when performing the cooking operation, in order to perform the operation in the vicinity of the sink side wall 3, the amount of movement of the hand is reduced by the side wall, so that a problem occurs in performing the cooking operation. As described above, the vicinity of the sink side wall 3 is a space that is not frequently used. In the present invention, in the sensor unit 6 installed on the sink side wall 3, the vicinity of the sink side wall 3 is set as a detection range, so that it is possible to detect that the detected object enters the space not normally used. Therefore, since it becomes possible to determine that the object has entered the detection range of the sensor unit 6 in order to open and close the valve 4, the operation and the object are generally placed. Disturbances are less than setting a detection range in space, and false detection can be reduced.

A detection method of the sensor unit 6 when the vicinity of the sink side wall is set as a detection range will be described. By making the detection range of the sensor unit 6 in the vicinity of the sink side wall, it is possible to reduce false detections that occur during cooking operations, installation of objects, etc., but it is also possible to further reduce false detections by a detection method. For example, there is a method of confirming detection when the detected object moves in the detection range to decelerate. If this method is used, if the detected object is brought close to the sensor unit 6, a deceleration is generated because the detected object is moved with respect to the side wall. If there is, the vehicle does not decelerate because it tries to pass by avoiding the side wall, so that it is possible to prevent erroneous detection of the passing object. In addition, for example, there is a method of confirming detection when the detected object is substantially stationary in the detection range. With this method, since the sensor unit 6 is operated, it is possible to detect a stationary motion after decelerating and confirm the detection, thereby preventing erroneous detection due to the movement of an object in the vicinity of the sink side wall. It becomes possible. Note that “substantially stationary” refers to a state in which the state is completely stopped, or a slight fluctuation occurs when a human body that is a detected body or a hand holding the detected body stops. In addition, for example, there is a method of confirming detection when it is detected that the object is accelerated after detecting stationary or deceleration of the object in the detection range. With this method, it is possible to detect the movement of the detected object from the faucet 1 to the washing water discharged from the faucet 1 after the object has entered the detection range. It is also possible to prevent an erroneous water discharge by detecting a substantially stationary state when an appliance or the like is installed. The detection accuracy can be improved by combining the above detection methods singly or in combination. Furthermore, by adding the distance information of the object within the detection range, it becomes possible to obtain further information about the object within the detection range, so that it is possible to prevent erroneous detection during cooking operations, installation of cooking utensils, etc. It becomes possible.

Here, as the detection unit that constitutes the sensor unit 6 that can achieve sensing within the detection range as described above, for example, a vibration wave is transmitted to the outside, and an object based on the reflected wave reflected from the detection target is used. There are ultrasonic sensors that detect movement and radio wave sensors. In ultrasonic sensors and radio wave sensors, it is possible to detect the movement of an object by the Doppler effect, so it is possible to detect movements such as deceleration, almost stationary, and acceleration, and to obtain distance information. Therefore, it can be said that it is suitable for the detection method as described above. Further, in the radio wave sensor, since it is possible to pass through an object such as resin, when the sink 2 made of a resin member is used,
Since the sensor unit 6 can be concealed, sensing can be performed without impairing the appearance of the sink 2.

In this embodiment, the above-described radio wave sensor is used, the frequency to be used is set in the vicinity of 10.5 GHz, and a detection range that can be operated without contact is set. In the present invention, the same effects as those of the present invention can be obtained regardless of the selection of the frequency to be used and the setting of the detection range so as to perform the contact / non-contact operation.

As described above, when the sensor unit 6 is installed on the sink side wall 3, the location of the sensor unit 6 is unclear depending on the location where the kitchen is used. Therefore, in the present invention, when the sensor unit 6 is installed on the sink side wall 3, a guide unit that prompts the user to operate is provided on the counter upper surface 8 adjacent to the sink side wall 3 on which the sensor unit 6 is installed. . Since the counter upper surface 8 becomes a place where it can be seen when using the kitchen, it is possible to recognize the location of the sensor unit 6 without depending on the place where the kitchen work is performed. It is possible to perform all operations without hesitation, so that the user does not hesitate to operate, and the detected object in the sensor unit 6 can be reliably detected, so that false detection can be reduced. Become.

FIG. 1 shows a case where the sensor unit 6 is installed on the left side wall of the sink. Since the sensor unit 6 is installed on the sink side wall 3 on the left side, the guide unit 7 is provided on the counter upper surface 8 adjacent to the left side of the sink 2 in the drawing. By installing in this way, the guiding portion 7 is provided on the counter upper surface 8 even when the cleaning operation is being performed while the counter adjacent to the left side of the sink is being cooked. Even when the position of the installed sensor unit 6 is unclear, it is possible to grasp the approximate location, so that the sensor unit 6 can be easily operated. Further, since the counter upper surface 8 has only the guiding portion 7 and the sensor portion 6 is located on the sink side wall 3, even when all the counter portions are used in the cooking operation, the operation in the cooking operation, cooking utensils, etc. are installed. In addition, since an object does not enter the detection area, erroneous detection can be prevented.

The guidance unit 7 will be described. Since the guidance part 7 is for urging the user to operate the installation location of the sensor part 6, it is desirable that the guidance part 7 be easily recognized by the user. For example, as shown in FIG. 3A, the “arrow” is used to guide the installation location of the sensor unit 6, or the user's operation is urged by text as shown in FIG. 3B. In addition, since the guide means 7 is a part of the appearance of the kitchen because it is installed on the counter upper surface 8, it is desirable to use a size, shape, etc. that do not impair the appearance of the kitchen. For example, the position of the sensor unit 6 is indicated by configuring the guide unit 7 using a circular shape as shown in FIG. 3C or a cornered shape as shown in FIG. It is what you want to do. In kitchens, it is often used by a specific user rather than an unspecified number of users as in public facilities, so the appearance may be damaged as shown in FIGS. 3 (A) and 3 (B). Instead, as shown in FIGS. 3C and 3D, the position of the sensor unit 6 can be grasped and the appearance is not impaired by making the shape such that the appearance is not impaired. Since the guide unit 7 is a display, there are, for example, a method of causing the counter to emit light using an illumination device such as an LED, a method of displaying the counter by painting, and a device that can be marked like a seal. Regarding the method of emitting light, it is necessary to process the counter in order to install the lighting equipment that emits light, or it is necessary to install a device for emitting light from the ceiling separately, but there is also the effect of directing the kitchen with lighting In addition, the guiding unit 7 can be recognized even in a dark place where the lighting of the kitchen is not turned on. Moreover, in the display method by painting, since the guidance part 7 can be created collectively at the time of kitchen manufacture, the guidance part 7 can be easily mounted on the kitchen. In addition, in the seal, when replacing the faucet 1, the sensor unit 6 is installed later, or when the sensor unit 6 is removed, the guide unit 7 can be easily installed / removed. Or it becomes possible to modify | repair, without impairing an external appearance in the case of a change from the kitchen with the sensor part 6. FIG.

Next, the installation method of the guidance | induction part 7 is described. The guide portion 7 disposed on the counter upper surface 8 is used when working from a place where the sink side wall 3 cannot be seen. For example, the case where there is a person in front of the counter on the left side of the sink shown in FIG. In the case of use from such a place, since the counter upper surface 8 is visible, it is possible for the guiding portion 7 to enter the detection area of the detected object. Thus, in the case of an operation from a place where the sink side wall 3 where the sensor unit 6 is installed cannot be seen, the sink side wall 3 is inserted obliquely with respect to the counter upper surface 8 as shown in FIG. This is because the hand is movable with the shoulder located above the counter upper surface 8 as a fulcrum, so that the human body is inserted obliquely from above. At this time, the insertion is such that the finger comes to the rear edge side of the system kitchen and the palm comes to the front edge side of the sink, and the fingertip is inserted to the lower side of the sink than the palm. Here, in order to efficiently reflect the transmission signal 9 from the sensor unit 6 and receive the reflected transmission signal 9 as a large reception signal, it is desirable that the sensor unit 6 has a flat shape and no gap. In the detection object, since there are many metal utensils and flat shapes, the transmission signal 9 can be reflected efficiently, so that a large reception signal can be obtained. It was confirmed that the reflected signals were different, and it was confirmed that the place where the transmission signal 9 can be reflected most efficiently is the palm (see FIG. 6). Therefore, in the present invention, in order to improve the detection accuracy, the transmission signal 9 can be transmitted to the palm of the object to be detected, particularly the human hand so that the transmission signal 9 from the sensor unit 6 can be efficiently reflected. It is something to do.

First, when the user confirmed how to operate the guidance unit, it was confirmed that the user operated near the finger (see FIG. 7). In general, this is performed because there are many operations with a finger when a switch or the like is operated, and a fine operation or the like is easy. The same tendency was confirmed when the operation was prompted for 6. Further, as shown in FIGS. 7A and 7B, the location of the guide portion 7 is changed in the front-rear direction of the sink 2 to confirm the hand operation on the guide portion 7; It was confirmed that the user operated near the finger. From the above, in order to operate the guidance unit 7 near the finger and to place a palm on the front surface of the sensor unit 6, the system kitchen rather than the center of the sensor unit 6 as shown in FIG. 8. By disposing the guiding portion 7 on the trailing edge side, it becomes possible to guide the palm immediately before the sensor portion 6, so that a large received signal can be obtained and detection accuracy can be improved. Become.

Furthermore, regarding the installation position of the sensor unit 6, it is desirable to install it above the sink side wall 3 as shown in FIG. As described above, with respect to the insertion of the human hand, the palm is guided to a position close to the counter upper surface 8 because the hand is inserted in an oblique direction. Therefore, by disposing the sensor unit 6 in the vicinity of the counter upper surface 8 of the sink side wall 3, it is possible to approach the palm, so that a large reception signal can be obtained and detection accuracy can be improved. .

Here, the schematic block diagram of a kitchen is shown in FIG.10 and FIG.11. In general, in kitchen cooking work, in order to perform cooking around the water and cooking, work such as cutting and mixing is often performed in the work space 17 existing between the sink 2 and the heating cooker 18. Work space 17
By performing the cooking operation, the movement to the sink 2 and the heating cooker 18 can be easily performed, and the cooking operation in the kitchen can be efficiently performed. Therefore, in the present invention, it is desirable to provide the sensor unit 6 on the sink side wall 3 adjacent to the cooking space, and to provide the guide unit 7 on the counter upper surface 8 in the cooking space. Since the sensor unit 6 is provided on the sink side wall 3 adjacent to the cooking space, the user cannot find the sink side wall 3 on which the sensor unit 6 is installed from the user in the cooking space. However, by disposing the guide portion 7 on the counter upper surface 8 of the cooking space, the location of the sensor unit 6 can be confirmed from the cooking space, so that it can be easily operated. Moreover, since the sensor part 6 is provided on the side wall adjacent to the cooking space in this way, the sensor part 6 and the guide part 7 are installed on the flow line of the hand from the work space 17 to the faucet 1. Because it is possible to operate the water stoppage on the way to the wash water without operating by extending the hand to operate the valve 4 for controlling the water stoppage such as an installed single lever. It is possible to operate the kitchen more efficiently without moving the center of gravity of the user's body and without putting a load on the body only for operations such as reaching out. .

Thus, even when the sink side wall 3 on which the sensor unit 6 is disposed cannot be visually observed by disposing the guide unit 7 on the counter kitchen top side 8 from the installation position of the sensor unit 6, the sensor unit 6 can be surely urged to insert the object to be detected, so that it is possible to eliminate the ambiguity of the place where the user operates the sensor unit 6, improve the detection accuracy, and supply water.

Next, an operation from a place where the sink side wall 3 on which the sensor unit 6 is installed can be seen will be described. Here, although the sink side wall 3 in which the sensor unit 6 is installed is visible, the case of the sensor unit 6 concealment method in which the sensor unit 6 itself is arranged so as not to be visible will be described. As shown in FIG. 12, when a user is on the front edge side of the sink 2, which is a place facing the faucet 1, the sink side wall 3 in which the sensor unit 6 is installed rather than the guide unit 7 on the counter upper surface 8. It is easier for the user to visually check if the guiding means 7 is provided. Therefore, a configuration in which the guide portion 7 is provided on the sink side wall 3 on which the sensor portion 6 is installed will be described.

When the guide unit 7 is installed on the sink side wall 3 provided with the sensor unit 6, the transmission signal 9 from the sensor unit 6 is efficiently transmitted as in the case where the guide unit 7 is installed on the counter upper surface 8 shown above. It is desirable to install in a place where the object to be detected can be guided so as to reflect well and obtain a large received signal. Therefore, since it is possible to obtain a sufficiently large reception signal for metal items such as cooking utensils and flat items, in this embodiment, it is difficult to obtain the reception signal as in the above. Describes the results of the investigation. As in the case where the guide unit 7 is installed on the counter upper surface 8, it is desirable to detect a palm which is flat with respect to the hand and has a small gap so that the transmission signal 9 is not lost. Therefore, a method of arranging the guide unit 7 with respect to the sensor unit 6 so that the palm comes immediately before the sensor unit 6 will be examined. Here, as in FIG. 7, when the guide portion 7 is installed on the sink side wall 3, it was confirmed in which part the guide portion 7 was operated (see FIG. 13). As a result, similarly to the case where the guide portion 7 is provided on the counter upper surface 8, the guide portion 7
It was confirmed that it was operating near the finger. Therefore, when the guide part 7 is provided on the sink side wall 3 on which the sensor part 6 is installed, the guide part 7 is arranged on the rear side of the system kitchen from the mounting position of the sensor part 6 as shown in FIG. When the user performs an operation on the guide unit 7, a palm is placed immediately before the sensor unit 6 so that the transmission signal 9 is reflected efficiently, so that a large received signal is obtained. This makes it possible to reduce false detections.

Further, as a means for further improving the detection accuracy, it is desirable to arrange the guide portion 7 below the sink portion with respect to the sensor portion 6 as shown in FIG. This is because even when the sink side wall 3 is visible, the arm is moved with reference to the shoulder above the sink, so that the hand held over the sink side wall 3 has the fingertip below the sink and the palm above the sink. Inclined and presented. Therefore, by installing the guiding means 7 below the sink than the sensor unit 6, it becomes easy to install the palm immediately before the sensor unit 6, so that the received signal can be detected more reliably and the detection accuracy is improved. It becomes possible.

Next, in the case where the guide portion 7 is arranged on the sink side wall 3 and the counter upper surface 8, FIG.
6. By providing these two guiding portions 7, it is possible to guide the hand to the sensor portion 6 even when the sink side wall 3 is visible / impossible, and the detection accuracy is improved. Needless to say. Here, when the guide part 7 is installed on the sink side wall 3 where the sensor part 6 is installed, the amount of operation near the fingertip is larger than when the guide part is installed on the counter upper surface 8. This is because the guiding portion 7 is close to the insertion place of the hand and the guiding means 7 can be visually observed. Therefore, by directly operating the guiding portion 7, the fingertips can be operated at intervals of operating a conventional switch or the like. It seems that this is a matter generated by the operation.
Therefore, in the present invention, the installation location of the guide portion 7 arranged on the counter upper surface 8 and the guide portion 7 installed on the sink side wall 3 on which the sensor unit 6 is installed are different, and the guide installed on the sink side wall 3 is different. The part 7 is configured to be arranged on the system kitchen rear edge side with respect to the guide part 7 installed on the counter upper surface 8. Thereby, even when the user cancels the sink side wall where the sensor unit 6 is installed from a position where the sink side wall is visible / impossible, the palm can be guided immediately before the sensor unit 6, so that the detection accuracy is further improved. It becomes possible to raise.

Here, for the sensor unit 6 of the present invention, a sensor that is disposed behind the sink side wall 3 and detects over the sink side wall 3, for example, a radio wave sensor is desirable. Since this is disposed on the back side of the sink side wall 3, the sensor section 6 is formed from the surface of the sink 2 (inside the sink).
Therefore, the appearance of the sink 2 can be maintained. Further, it is desirable to set the detection region and the detection criterion so that the operation on the sensor unit 6 when using the radio wave sensor is a non-contact type operation. In kitchen work, your hands may be soiled with detergents and ingredients, and if you perform a contact-type operation in this situation, dirt will adhere to the contacted part, and there will be work to clean the dirt. The possibility of erroneous detection due to negotiated dirt increases. Therefore, non-contact operation can provide a kitchen with improved cleanability and less false detection.

As described above, according to the present embodiment, the sensor unit 6 is installed on the sink side wall 3, and the guide unit 7 is installed on the counter upper surface 8 or the sensor unit 6 to prompt the user to operate the sensor unit 6. By providing it to the sink side wall 3, even when the sensor installation location and detection area are unclear, such as a concealed sensor, the user is guided by guiding the palm toward the sensor unit 6. Operation can be performed without hesitation, and a large received signal can be obtained by detecting the palm, so that detection accuracy can be improved and false detection can be reduced.

Further, when the display of the guide unit 7 is composed of a light emitting body such as an LED, the detected form is detected by the sensor unit 6 and the display form changes between when the valve 4 is opened and when the valve 4 is closed. By doing so, the user can intuitively determine the operating state of the system kitchen. For example, when the guidance unit 7 is lit when the sensor unit 6 is operated, it is possible to intuitively determine the position to be presented and whether the sensor unit 6 is being activated. In addition, after the operation, the guidance unit 7 is turned off, so that the sensor unit 6 can detect the detected object and intuitively determine that water has been discharged from the water discharge unit 1, and the guidance unit 7 is turned off. Therefore, it is possible to concentrate on the washing work without worrying about the display of the guide unit 7.

When using an infrared sensor or radio wave sensor in the system kitchen, in order to prevent a reduction in detection accuracy, for example, to cancel a noise signal due to fluorescent light around the sensor or reflected light reflected from the illumination light on the sink Adjustment time is required. Furthermore, when the sensor unit 6 is installed on the sink wall surface 3 as in the present invention, it is necessary to cope with changes in the detection signal due to the influence of a pan, a plate, a cup, or the like placed in the sink. Therefore, the adjustment time for canceling these noises is long and the adjustment frequency is also high. For example, the user may put out his / her hand with respect to the guiding portion 7 during the adjustment time, and may not be detected or detected erroneously. Becomes higher.

In order to solve the above problem, the guide unit 7 has a notification function for notifying the user of the operation state of the system kitchen. Depending on the operating state of the system kitchen, it is possible to easily determine, for example, whether the user can use the operation by the sensor unit 6 by changing the notification form by the guide unit 7, so that a more reliable operation is possible. I can do it. Moreover, since the guidance part 7 is provided with a notification function, the user can recognize the operation state of the system kitchen by looking at the operation part, so that the work can be performed more smoothly.

In addition, in this invention, since the guidance | induction part 7 is provided with the alerting | reporting function, the position of the alerting | reporting function in this invention acquires the effect similar to the effect which the installation position of the guidance | induction part 7 has.

Since the sensor unit 6 is affected not only by noise signals such as lighting around the system kitchen, but also by noise signals due to tableware placed in the sink 2, the sensor unit 6 is used as a detection target as shown in FIG. There is a possibility that the adjustment time 100 for adjusting to an optimum state for detection becomes longer. Therefore, when the sensor unit 6 is in a state where the user cannot detect the water discharge operation during the adjustment time 100 and the sensor unit 6 is in a state where the sensor unit 6 can detect the water discharge operation by the user, the guide unit 7 17 shows a state in which the valve 4 is open as shown in FIG. 17, a display form during the adjustment time 100, and a display in a state in which the valve 4 is closed and the sensor unit 6 can detect the water discharge operation by the user. Change form. By not changing the display form of the guide portion 7 when the valve 40 is closed during the adjustment time 100, it is possible to prevent the user from operating the sensor unit 6 during the adjustment time 100, which is more reliable for the user. Operation becomes possible.

Moreover, in order for the guidance | induction part 7 to alert | report a user that the sensor part 6 is in the adjustment time 100, a display form may change. For example, as shown in FIG. 18, the valve 40 is open, the valve 4 is closed, the sensor unit 6 cannot detect the water discharge operation by the user, the valve 4 is closed, and the sensor The display form may be different between the state in which the unit 6 can detect the water discharge operation by the user. By changing the display form in this way, the user can recognize the operation state of the sensor and the operation state of the valve 4 in more detail.

Depending on the state used by the user, an object placed in the sink 2 may hardly affect the signal of the sensor unit 6. In such a case, the adjustment time 100 may be extremely short. Therefore, if the time 100 until the adjustment is completed can be determined before the adjustment is started or during the adjustment, the user can operate during the adjustment time 100 when the adjustment time 100 is extremely short so as to be less than the predetermined time. Therefore, even when the valve 4 is closed and the adjustment time 100 is in progress, the guide unit 7 may be changed to a display form in which the valve 40 is closed and there is no adjustment time. This eliminates the need for the process of determining whether or not the adjustment has been completed, so that it is possible to notify the user that the sensor unit 6 can be operated more quickly, and the user can work more efficiently. Can be done. As an example of a method for determining whether or not the adjustment time 100 is short before or during the adjustment, the voltage value 110 acquired from the sensor unit 6 as shown in FIG. 19 and the target voltage value 112 after the end of the adjustment. There is a method using the difference between the two. That is, when the value 113 corresponding to the absolute value of the difference value exceeds the predetermined threshold value 111, it is determined that the adjustment time 100 is not short. When the value 105 corresponding to the absolute value of the difference falls below a predetermined threshold 111, it is determined that the adjustment time 100 is short.

Here, the notification function of the guiding unit 7 may be configured by a sound output device such as a speaker. By notifying the operation state of the system kitchen to the user by sound, the user does not need to move the human body to visually recognize the notification unit, and can work more efficiently.

Moreover, the guidance | induction part 7 has an effect similar to the change of a display form by changing the timing which a display form changes, and the said sound output device alerting | reporting form similarly.

The sound output device may change the notification form when the valve 4 is opened. As a result, for example, when the child performs water discharge using the sensor, even if the adult is away from the system kitchen, the operation state can be confirmed by sound, so that attention can be directed to the child.

The guiding unit 7 may be provided with a sound output device whose notification form changes substantially simultaneously with the change of the display form, and it is difficult to hear the sound emitted from the sound output device when the surroundings of the system kitchen are noisy. In the environment, the operating state of the system kitchen can be recognized by the display state, and in other environments, the operating state of the system kitchen can be recognized by the notification sound without looking at the display unit. More efficient work can be done.

The number of guiding portions 7 whose display form changes does not have to be only one on each surface as shown in FIG. 16 and the like. For example, by arranging a plurality of guiding portions 7 as shown in FIG. When the time becomes shorter as time passes, the user can be notified of the time required until the adjustment time by changing the display form of each display unit. In addition, when the sensor unit 6 is in a state in which the user's operation can be detected, it is possible to achieve the effect as the guide unit by lighting the guide unit 7 at the optimum position as the guide unit.

Moreover, you may change the display form of the guidance | induction part 7, and the alerting | reporting form by a sound output device not only the information regarding the sensor part 6, but the temperature of the water discharged from the faucet 1, and the water discharge form. For example, the system kitchen is equipped with a sensor that detects the temperature of water discharged from the water discharge unit, and based on the detected temperature, for example, red for a high temperature, orange for a suitable temperature, blue for a low temperature So that the color of the display changes. As a result, the user can perform a water discharge operation with the sensor unit 6 and can roughly recognize the temperature of the water discharged from the faucet 1 before touching the water, so the user accidentally puts his hand into the hot water. Can reduce the risk of burns. Also, since the water discharge temperature rises to the set temperature by operating the water heater and you can visually check whether it is at the appropriate temperature, you can work more comfortably without getting your hands on unwarmed water. Can be done.

The change in the display form of the guiding unit 7 is, for example, changing the display cycle such as lighting to flashing, changing the display color such as red to blue, changing the display color from lighting on to off, or lighting from off to on. Say to change.

The change of the notification form of the sound output device means that, for example, a sound is continuously output for a predetermined time or a sound is periodically output for a predetermined time. Moreover, you may change a timbre according to the operation state of a system kitchen.

Further, the faucet 1 is provided with a rotation mechanism so that the user can wash it at a position where it can be easily washed. By rotating the faucet 1, the display form of the guide portion 7 may be changed. Since the angle at which the faucet 1 is to be rotated can be adjusted while confirming with the display unit 61, it is easy to match the target rotation angle.

In addition, the system kitchen is equipped with a mechanism that allows part of the faucet 1 to be attached and detached so that the user can remove and use part of the faucet 1 when cleaning the inside of the sink. The display form of the guiding unit 7 may change depending on the state of not being used. For example, when the faucet 1 is disconnected, the display of the guiding unit 7 blinks, and when it is not disconnected, the guiding unit 7 is turned on. Thereby, when the faucet 1 is separated and used, it can be easily confirmed in the display state whether the faucet 1 can be accurately returned. Therefore, the user mistakenly recognizes that the faucet 1 has been replaced. When the water is discharged, the danger of the faucet 1 wobbling due to the water pressure due to the discharged water flow and the discharged water flow out of the sink can be reduced.

The signal processing unit 14 may perform automatic water stop control based on a signal obtained by reflecting the radio wave radiated from the sensor unit 6 to the water discharged from the faucet 1. Specifically, when a hand or an object is inserted in the water discharge flow and the water discharged by the water discharge hits the cleaning object, the valve 40 is kept open to continue the water discharge. Is not inserted and when the water reaches the sink 2, the automatic water stop control is performed by closing the valve 40. By allowing the user to stop the water without any operation, for example, it is possible to prevent the water from being drained after rinsing a dish or the like and moving it to a drainer.

The system kitchen may include an operation unit that forcibly stops detection by the sensor unit 6. By providing the operation unit, for example, it is possible to save driving power of the sensor unit 6 or to prevent erroneous detection when performing work in the detection area 51, for example, wiping and cleaning. In addition, by operating the operation unit, the user can easily recognize that the user has operated the operation unit and the operation result by changing the display form of the guide unit 7. . Also, by performing the operation unit with the sensor unit 6, it becomes possible to eliminate parts for newly configuring the operation unit, the number of parts is reduced, the design is simplified, and the design of the system kitchen is achieved. Is more effective.
