Description

Description: BACKGROUND OF THE INVENTION The present invention can control the position, such as the ejection amount, direction, and angle of a fluid used for washing a portion to be washed by ejecting a fluid such as washing water. The present invention relates to a cleaning control device.

2. Description of the Related Art In a conventional cleaning control device, for example, in a sanitary cleaning device used for a toilet, a selection is made from a family button or a ladies' button, and an injection port suitable for each purpose is selected. Thereafter, the opening and closing of the injection port is controlled, and the swinging control of the movable portion is performed to clean a certain range of the portion to be cleaned by the user.

The spout is set to an approximate position where the part to be cleaned will be located, and then the opening is opened to eject the fluid toward the part to be cleaned, and the jet is applied to the part to be cleaned.

Problems to be Solved by the Invention However, such a jet does not always hit the part to be cleaned by the user, and the user takes a place that is presumed to be the part to be cleaned in the passage of the jet, It is to be washed. Further, since the portion to be cleaned has a certain area, the user cleans the entire region of the portion to be cleaned by moving the portion to be cleaned.

In order to reduce the movement of the part to be cleaned, the ejection port having the movable part is moved so that the user does not have to move the part to be cleaned as much as possible. .

However, there is no accurate information on where the part to be cleaned is in any of the methods, and since the liquid is ejected from the ejection port by estimation, it is necessary to accurately apply a jet to the shape of the part to be cleaned by various users. However, there is a problem that the user has to move the part to be cleaned by himself.

Also, the user had to choose between a family button or a ladies button next to the toilet seat.

In view of the above, the present invention solves the above-described problems, and identifies a man and a woman, and performs movement of a user by detecting a representative position of a part to be cleaned and a region to be cleaned to match the characteristics of the gender. The purpose is to wash properly without causing it to fall.

Means for Solving the Problems In order to achieve the above object, the present invention provides an ejection port provided with a liquid outlet, a position control means for controlling a position at which a fluid coming out of the ejection port hits a portion to be cleaned, and An imaging unit that monitors a state in which fluid ejected from the mouth is supplied to the portion to be cleaned and outputs the image as an image signal; a gender determination unit that determines a user's gender based on an image signal from the imaging unit; A control unit that outputs a control signal to the position control unit so as to determine a position of the cleaning unit to be cleaned based on an image signal from the unit.

The cleaning control device of the present invention monitors the state of the imaging unit being supplied to the part to be cleaned of the fluid from the ejection port after the gender determination unit performs the gender determination based on the image signal from the imaging unit according to the above configuration. The image is output as an image signal, and the control unit controls the position of the injection port by the position control means based on the image signal, determines whether it is stool or urine, and determines the representative point of the cleaning unit to be cleaned and the representative point. This has the effect of appropriately cleaning the nearby cleaning area.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a toilet bowl, 2 is a toilet seat on which a user 3 sits, 4 is a washing water tank that supplies a fluid to a nozzle 5 via an on-off valve 6, and 7 is a nozzle that moves the nozzle 5 through a movable portion 8. Position control means 9 for moving up, down, left, and right is a telescopic part 10 of the nozzle 5
It is configured such that the toilet seat protrudes and retracts by water pressure at an injection port provided near the tip of the toilet seat. Further, an imaging unit 12 for monitoring the part to be cleaned 11 of the user 3 is installed near the nozzle. The imaging unit 12 is connected to the gender determination unit 13 and the control unit 14, and the position control unit 7 is configured to be connected to the control unit 14. In addition, the control unit 14 recognizes the cleaning target 11 from the image signal to start the cleaning operation by the support from the operation unit 15, and determines the cleaning degree of the cleaning target 11 from the recognition unit 16. The determination unit 17 includes a position indicating unit 18 that outputs a control signal to the position control unit 7 to determine the position of the cleaning target 11 to be cleaned based on the recognition unit 16 result and the determination result of the determination unit 17. .

 The operation of the above configuration will be described.

When the user 3 sits on the toilet seat 2, a switch (not shown) is turned on, and an image before use is captured from the imaging unit 12 into the memory of the gender determination unit 13 and the recognition unit 16. The gender determination unit 13 performs feature extraction by image processing such as edge detection of the image.If a man has a male genitalia, it is determined that the man is a male by this edge extraction. I do. In addition, the first image captured by the recognition unit 16 is used as an initial image, and a shape is extracted by a process such as edge detection of the initial image to obtain a representative point in the to-be-cleaned portion 11 where excrement appears. Using the representative point as a reference point, the recognition unit 17 extracts the feature of the edge around the part to be cleaned 11 and performs shape recognition.

Next, after use, the user 3 operates the operation unit 15 to capture the current image from the imaging unit 12 into the recognition unit 17 and perform shape extraction by image processing such as edge detection to obtain a representative point of the part 11 to be cleaned. . Similarly, using the representative point as a reference point, the recognition unit 16 extracts features of edges around the portion 11 to be cleaned and performs shape recognition. After that, by matching the representative point of the current image with the representative point of the initial image, the shape of the initial image is matched with the shape of the current image, and the determination unit 17 compares the colors at the same point. Here, if there is no color change and the woman is a woman in the gender determination section 13, bidet washing is performed. If there is color change and a woman, perform bidet washing and anal washing. In the case of a male in the gender determination section 13, anal cleaning is performed.

Here, anal cleaning will be described. As long as there is a color change between the initial image and the original image, it is determined that cleaning has not been performed yet as a result of the determination. The on-off valve 6 is opened, and the fluid is supplied from the cleaning tank 4 to the nozzle 5. Here, from the contracted state of the expansion / contraction part 10 of the nozzle 5, it expands into the toilet seat according to the instruction of the position instruction part 18 by water pressure and ejects the fluid from the ejection port. In the present invention, the representative point is first washed. This operation is performed until there is no change in the judgment unit 17, and then the recognition unit
The inside of the area to be cleaned obtained at 17 is scanned spirally in accordance with the instruction of the position instruction unit 18. Judgment unit 17 for all areas to be cleaned
If there is no change, the cleaning is completed, the on-off valve 6 is closed, and the telescopic portion 10 of the nozzle 5 is contracted so that the nozzle 5 is submerged from the toilet seat.

Note that the determination by the determination unit has been described using a method of detecting a change in color, but the same effect can be obtained by using luminance information or the like as long as the change between before and after cleaning is known. In addition, the order of the cleaning positions may be a scan from the end instead of a spiral shape.

Effect of the Invention As described above, in the present invention, the cleaning of the portion to be cleaned can be performed only by pressing the cleaning button to recognize the stain on the portion to be cleaned by the image without selecting the family button and the ladies' button. At this time, it is not necessary for the user to move the portion to be cleaned to the portion to be cleaned into the passage of the jet stream, and to move the portion to be cleaned. Further, whether or not the cleaning is completed can be automatically detected, and energy can be saved and time can be saved because unnecessary fluid is not required.
