An "automatic washing machine" according to a first embodiment of the present invention will be explained with reference to FIGS. 1 to 4. The automatic washing machine 1 shown in FIG. 1 is installed in a restroom or the like, and includes an oval bowl 2, a soap water spout (soap water discharging means) 3, and a wash water spout (wash water discharging means) 4. , a warm air blowing unit (air blowing means) 5, a single area sensor 10 that detects the object to be detected in the bowl 2, and a soap water spout 3 and a cleaning water spout 4 according to the detection result of the area sensor 10. , and an operation response unit (not shown) that operates the warm air blowing unit 5.

The soapy water spout 3 protrudes from the left side portion of the back wall surface of the bowl 2. In this example, the soapy water spout 3 spouts foamy soapy water toward the center of the bowl 2, but it may be configured to spout liquid soapy water.

The cleaning water spout 4 protrudes from the right side of the back wall surface of the bowl 2 and spouts cleaning water (tap water in this example) toward the center of the bowl 2.

The hot air blowing section 5 is provided at the center of the front wall surface of the bowl 2 and blows hot air toward the center of the bowl 2. Further, this hot air blowing section 5 is provided for the purpose of drying wet hands.

Note that the directions "left", "right", "rear", and "front" described in this specification are directions as seen from the user of the automatic washing machine 1.

Area sensor 10 is arranged within the wall of bowl 2. The area sensor 10 detects the presence or absence of objects to be detected in areas E1, E2, and E3 in FIG. The "detected object" is intended to be the hand of the user of the automatic washing machine 1. The area E1 is a position in front of the soapy water spout 3 and where the soapy water discharged from the soapy water spout 3 is applied. The region E2 is near the hot air blowing section 5 and is a position where the warm air blown out from the hot air blowing section 5 hits with force. The area E3 is a position in front of the cleaning water spout 4 and where the cleaning water discharged from the cleaning water spout 4 is applied.

The operation response section is composed of a control device and the like. When the area sensor 10 detects a detection target in the area E1, the operation response unit controls the operation of a soapy water supply pump (not shown) to discharge soapy water from the soapy water spout 3. Further, when the area sensor 10 detects a detection target in the region E3, the operation response unit controls the operation of a cleaning water supply valve (not shown) to discharge cleaning water from the cleaning water spout 4. Further, when the area sensor 10 detects a detection target in the area E2, the operation response unit controls the operation of a fan and a heater (not shown) to blow out warm air from the warm air blowing unit 5.

FIG. 2 is a schematic configuration diagram of the area sensor 10 of this example. As shown in FIG. 2, the area sensor 10 includes a substrate 11, a plurality of light emitting elements L1, L2, L3, a plurality of irradiation lenses 13, one PSD (optical position detection element) 12, and one light receiving element. 14, a microcomputer (computation unit) 15, and a case (not shown) that holds the substrate 11 and lenses 13 and 14. A plurality of light emitting elements L1, L2, L3, a PSD 12, and a microcomputer 15 are mounted on a substrate 11.

In this example, the light emitting elements L1, L2, and L3 are surface-mounted infrared LEDs. These light emitting elements L1, L2, L3 are arranged in one row on the substrate 11.

The irradiation lens 13 is provided for each light emitting element L1, L2, L3. These irradiation lenses 13 collimate the light emitted from the corresponding light emitting elements.

The set of the one light emitting element and the one irradiation lens 13 is referred to as a "light emitting unit" in this specification. That is, the area sensor 10 includes a plurality of light emitting units that each emit light toward different positions within the bowl 2. Note that a bullet-shaped LED may be used instead of the light emitting unit of this example. Further, in this example, in order to include the region E1, the region E2, and the region E3 in the detection region, the irradiation directions of adjacent light emitting units are set at an angle.

Specifically, the light emitted from the light emitting element L1 in FIG. 2 and collimated by the irradiation lens 13 passes through the region E1 in FIG. The light emitted from the light emitting element L2 in FIG. 2 and collimated by the irradiation lens 13 passes through the region E2 in FIG. The light emitted from the light emitting element L3 in FIG. 2 and collimated by the irradiation lens 13 passes through the region E3 in FIG. In addition, the light from these three light emitting units passes through a single light-transmitting window provided in the center of the back wall of the bowl 2 (between the soapy water spout 3 and the washing water spout 4), and enters the bowl 2. is irradiated.

The PSD 12 is mounted on the substrate 11 with its light receiving surface parallel to the substrate 11. Further, the PSD 12 is arranged between the light emitting element L2 and the light emitting element L3.

The light-receiving lens 14 is arranged to face the light-receiving surface of the PSD 12.

The set of the above-mentioned one PSD 12 and the above-mentioned one light-receiving lens 14 is referred to as an "optical position detection unit" in this specification. That is, the present area sensor 10 includes one optical position detection unit for a plurality of light emitting units. This optical position detection unit collects reflected light emitted from each light emitting unit and reflected by a detection target in the bowl 2 with a light receiving lens 14, and receives the light with a PSD 12. Then, the PSD 12 outputs a signal according to the light receiving position to the microcomputer 15.

The microcomputer 15 controls the light emission of the light emitting elements L1, L2, and L3. Further, the microcomputer 15 detects the presence or absence of the object to be detected in each irradiation direction of the light emitting unit based on the output signal from the PSD 12, and when detecting the presence of the object to be detected, specifies the position of the object. Then, it is determined whether the identified position is included in the above-mentioned area E1, area E2, and area E3. That is, the microcomputer 15 detects the presence or absence of a detection target within the area E1, area E2, and area E3 set on the light emitting axis of each light emitting unit.

FIG. 3 is an explanatory diagram for explaining the detection principle of the area sensor 10. As shown in FIG. Although only one set of light emitting units is shown in FIG. 3, the detection principle is the same for light emitting units that are not shown.
X: X (left and right) coordinates of the detection target (unknown value)
Y: Y (front/back) coordinate of the detection target (unknown value)
θa: Light receiving angle (unknown value)
xa: Distance from PSD reference to light receiving position (varies depending on measured value and position of detection target)
xn: Distance between parts (fixed value)
ya: Focal length of light receiving lens (fixed value)
θn: Emission angle (fixed value)

In FIG. 3, the coordinates (X, Y) of the detection target are determined by the following calculation.
tanθa=Y/X...(1)
tanθa=ya/xa...(2)
From (1) and (2),
Y=X・(ya/xa)...(3)
Also,
Since tanθn=Y/(X-(xn+xa)),
Y=(X-(xn+xa))・tanθn...(4)
From (3) and (4),
X・(ya/xa)=(X−(xn+xa))・tanθn
X・(ya/xa)=X・tanθn−(xn+xa)・tanθn
X・(ya/xa)−X・tanθn=−(xn+xa)・tanθn
X・((ya/xa)−tanθn)=−(xn+xa)・tanθn
X=((xn+xa)・tanθn)/(tanθn−(ya/xa))...(5)
X is obtained by substituting the fixed values xn, θn, ya, and the measured value xa into the above equation (5). Then, Y is obtained by substituting the obtained X, fixed value ya, and measured value xa into the above equation (3).

FIG. 4 is a timing chart showing the light emission timing of the light emitting elements L1, L2, and L3. The horizontal axis of this chart is the time axis. As shown in this timing chart, the microcomputer 15 sequentially causes the light emitting elements L1, L2, and L3 to emit light at predetermined intervals (5 msec intervals in this example), and repeats this light emission cycle. In this way, the microcomputer 15 detects the presence or absence of the object to be detected in each irradiation direction of the light emitting units by switching the light emission timing of the light emitting elements L1, L2, and L3.

The automatic washbasin device 1 configured as described above detects objects to be detected related to the discharge of washing water, detects objects to be detected related to the discharge of soapy water, and detects objects to be detected related to the blowing of hot air in a single area. Since the sensor 10 can cover the cost, costs can be kept down. In addition, since this automatic washing machine 1 has only one transparent window provided in the bowl 2, the design can be improved. Furthermore, since this automatic washroom device 1 uses only one sensor and has fewer wirings, it is possible to improve ease of assembly (workability).

An "automatic washing machine" according to a second embodiment of the present invention will be described with reference to FIG. 5. In FIG. 5, the same components as those in the first embodiment described above are designated by the same reference numerals, and the description thereof will be omitted.

The automatic washing machine 101 shown in FIG. The area sensor 110 includes an area sensor 110, and an operation response unit (not shown) that operates the multifunctional spout 6 and the hot air blowing unit 5 according to the detection result of the area sensor 110.

The multifunctional spout 6 is a combination of the soapy water spout 3 and the washing water spout 4 described in the first embodiment, and protrudes from the central portion of the back wall surface of the bowl 2. The multifunctional spout 6 spouts soapy water or washing water toward the center of the bowl 2 under the control of the operation response unit.

Area sensor 110 is arranged within the wall of bowl 2. The area sensor 110 detects the presence or absence of a detection target in the region E2 and the region E4 in FIG. 5, and the state of the detection target in the region E4. The "state of the detection target in area E4" will be described later. The region E4 is a position in front of the multi-functional spout 6 and is exposed to soapy water or cleaning water discharged from the multi-functional spout 6.

In this example, soapy water or washing water is spouted from the single multifunctional spout 6, but if the area sensor 110 detects that the object to be detected is "present" in the area E4, the user cannot discharge the soapy water. It is not possible to determine whether the request is for water discharge or the discharge of cleaning water. Therefore, in this example, the user's request is determined based on a complex condition that includes not only "the presence or absence of the detection target in the region E4" but also "the state of the detection target in the region E4." Specifically, the "state of the detection object" in the region E4 is the manner in which the hand moves and the hand spreads. That is, the area sensor 110 of this example detects the movement of the detection target and the occupied area in the area E4, analyzes this information, and determines whether the user is washing his hands (or is requesting the discharge of washing water). ), it is determined whether the user is trying to receive soapy water (or requesting soapy water to be discharged) with his or her spread and stationary palm.

When the area sensor 110 detects a detection target in the area E4 and determines that the user requests soapy water discharge, the operation response unit controls the operation of a soapy water supply pump (not shown), Soap water is discharged from a multifunctional spout 6. Further, when the area sensor 110 detects a detection target in the area E4 and determines that the user requests the discharge of cleaning water, the operation response unit controls the operation of a cleaning water supply valve (not shown). , to discharge cleaning water from the multifunctional spout 6. Further, when the area sensor 110 detects a detection target in the region E2, the operation response unit controls the operation of a fan and a heater (not shown) to blow out warm air from the warm air blowing unit 5.

The basic configuration and detection principle of this area sensor 110 are the same as those of the area sensor 10 described in the first embodiment (see FIGS. 2 and 3). In the first embodiment, the area sensor 10 was equipped with three light emitting units and one optical position detection unit corresponding to these, but the area sensor 110 of this example In order to detect the occupied area, this embodiment includes five light emitting units, which are more than the first embodiment, and one optical position detection unit corresponding to these units.

As shown in FIG. 5, the five lights from the five light emitting units are irradiated to different positions within the bowl 2 through a single transparent window provided in the center of the back wall of the bowl 2. Ru. The central light among the five beams passes through areas E4 and E2 in FIG. The pitch (distance between axes) of these five lights is set narrower than in the first embodiment.

As in the first embodiment, the microcomputer of the area sensor 110 sequentially causes the five light emitting units to emit light at predetermined intervals, and repeats this light emitting cycle. Then, the presence or absence of the detection target is detected for each irradiation direction of the light emitting unit, and if "present", the position of the detection target is specified in the corresponding irradiation direction.

Furthermore, when the position of the detection target changes during successive light emission cycles, the microcomputer of the area sensor 110 analyzes the position and detection timing of the detection target to determine the direction and amount of movement of the detection target. , and the speed of movement. By specifying these, the above-mentioned "hand movement" can be detected.

Furthermore, if there are multiple positions identified within the same cycle, the microcomputer of the area sensor 110 can identify the area occupied by the detection target by analyzing these multiple positions. Thereby, the above-mentioned "hand spread" can be detected.

As in the first embodiment, the automatic washing machine 101 configured as described above can detect objects to be detected related to the discharge of washing water, objects to be detected related to the discharge of soapy water, and objects to be detected related to the blowing of hot air. Detection can be performed by a single area sensor 110, so costs can be reduced and design and assembly efficiency can be improved. Furthermore, since the area sensor 110 can detect the state of the object to be detected (hand movement and hand spread), it is possible to adopt the multifunctional spout 6 that integrates a soapy water spout and a cleaning water spout. It becomes possible.

An "automatic washing machine" according to a third embodiment of the present invention will be described with reference to FIG. 6. In FIG. 6, the same components as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof will be omitted.

The automatic washing machine 201 shown in FIG. 6 includes a rectangular bowl 202, a soapy water spout 3, a washing water spout 4, a hot air blowing section 5, and a single area for detecting objects inside the bowl 202. It includes a sensor 210 and an operation response unit (not shown) that operates the soapy water spout 3, the cleaning water spout 4, and the hot air blowing unit 5 according to the detection result of the area sensor 210.

In the first embodiment, the hot air blowing section 5 was provided on the front wall surface of the bowl 2, but in this example, the soapy water spout 3, the washing water spout 4, and the hot air blowing section 5 are provided on the bowl 202. They are placed side by side on the back wall.

Area sensor 210 is located within the wall of bowl 202. Area sensor 210 detects the presence or absence of a detection target in area E6, area E7, and area E8 in FIG. The basic configuration and detection principle of this area sensor 210 are the same as those of the area sensor 10 described in the first embodiment, and therefore the description thereof will be omitted.

When the area sensor 210 detects a detection target in the area E6, the operation response unit controls the operation of a soapy water supply pump (not shown) to discharge soapy water from the soapy water spout 3. Further, when the area sensor 210 detects a detection target in the region E7, the operation response unit controls the operation of a cleaning water supply valve (not shown) to discharge cleaning water from the cleaning water spout 4. Further, when the area sensor 210 detects a detection target in the area E8, the operation response unit controls the operation of a fan and a heater (not shown) to blow out warm air from the warm air blowing unit 5.

As in the first embodiment, the automatic washbasin device 201 configured as described above can detect objects to be detected related to the discharge of washing water, objects to be detected related to the discharge of soapy water, and objects to be detected related to the discharge of hot air. Since the detection can be performed by a single area sensor 210, costs can be reduced and design and assembly efficiency can be improved.

An "automatic washing machine" according to a fourth embodiment of the present invention will be described with reference to FIG. 7. In FIG. 7, the same components as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof will be omitted.

The automatic washbasin device 301 shown in FIG. , an operation response unit (not shown) that operates the soapy water spout 3, the cleaning water spout 4, and the warm air blowing unit 5 according to the detection results of the area sensor 310.

The bowl 302 has an oval shape and is smaller than the bowl 2 of the first embodiment. In the automatic washing machine 301 of this example, the size of the bowl 302 is smaller than that of the first embodiment, but the arrangement of the soap water spout 3, the washing water spout 4, the hot air blowing part 5, and the area sensor 310 is the same as that of the first embodiment. It is the same as the form. Area E9, area E10, and area E11 in FIG. 7 correspond to area E1, area E2, and area E3 in FIG. 1 described in the first embodiment.

In the first embodiment, the soap water spout 3, the cleaning water spout 4, and the hot air blowing unit 5 were operated by detecting the presence or absence of the detection target in the areas E1, E2, and E3, but in this example Since the bowl 302 is small and the intervals between the areas E9, E10, and E11 are narrow, the user's request cannot be determined using the same detection method as in the first embodiment (only the presence or absence of a detection target in a predetermined area). difficult.

Therefore, in this example, the condition is determined from a complex condition that includes not only the "presence or absence of the detection target in area E9, area E10, and area E11" but also the "state of the detection target in area E9, area E10, and area E11." It is designed to determine the user's requirements. As in the second embodiment, the "state of the detection object" refers to the movement of the hand and the spread of the hand.

Specifically, when the detection target is detected in the area E9, the movement of the detection target is not detected (it is stationary), and the detection target occupies a predetermined occupied area including the area E9, The microcomputer of the area sensor 310 determines that the palm of the hand is spread out and stationary and is about to receive soapy water (requesting soapy water to be discharged).

Further, if a detection target object is detected in the area E11, a movement of the detection target is detected, and the movement satisfies a predetermined condition, the microcomputer of the area sensor 310 performs an action of washing hands ( (requesting cleaning water discharge).

Furthermore, when a detection target is detected in the area E10 and the detection target occupies a predetermined occupied area including the area E10, the microcomputer of the area sensor 310 detects that the area sensor 310 is holding its open palm (warm air blowout). request).

When the area sensor 310 detects a detection target in the area E9 and determines that the user requests soapy water discharge, the operation response unit controls the operation of a soapy water supply pump (not shown), Soapy water is spouted from a soapy water spout 3. Further, when the area sensor 310 detects a detection target in the area E11 and determines that the user requests discharge of cleaning water, the operation response unit controls the operation of a cleaning water supply valve (not shown). , the cleaning water is spouted from the cleaning water spout 4. Further, when the area sensor 310 detects a detection target in the area E10 and determines that the user requests hot air blowing, the operation response unit controls the operation of a fan and a heater (not shown), Hot air is blown out from a hot air blowing part 5.

The basic configuration and detection principle of this area sensor 310 are the same as those of the area sensors 10 and 110 described in the first embodiment and the second embodiment (see FIGS. 2 and 3). In the second embodiment, the area sensor 110 was equipped with five light emitting units and one optical position detection unit corresponding to these units, but the area sensor 310 of this example is In order to detect the state of the object to be detected, this embodiment includes seven light emitting units, which are more than the second embodiment, and one optical position detection unit corresponding thereto.

As shown in FIG. 7, the seven lights from the seven light emitting units are transmitted through a single light-transmitting unit provided in the center of the back wall surface of the bowl 302 (between the soap water spout 3 and the wash water spout 4). The light is irradiated through the window to different locations within the bowl 302. The second light from the left among the seven lights passes through region E9 in FIG. The center light among the seven lights passes through the area E10 in FIG. The sixth light from the left among the seven lights passes through area E11 in FIG. The pitch (distance between axes) of these seven lights is set narrower than in the second embodiment.

Similar to the first embodiment and the second embodiment, the microcomputer of the area sensor 310 causes the seven light emitting units to emit light in sequence at predetermined intervals, and repeats this light emitting cycle. Then, as in the second embodiment, the presence or absence of a detection target, the position of the detection target, and the state of the detection target are detected for each irradiation direction of the light emitting unit.

As in the first embodiment, the automatic washbasin device 301 configured as described above can detect objects to be detected related to the discharge of washing water, objects to be detected related to the discharge of soapy water, and objects to be detected related to the discharge of hot air. Since the detection can be performed by a single area sensor 310, costs can be reduced and design and assembly efficiency can be improved. Further, since the area sensor 310 can detect the state of the object to be detected (the movement of the hand and the manner in which the hand is spread), the user's request can be determined even within a narrow detection area. Therefore, a small bowl 302 can be used.

In the first embodiment described above, the soapy water spout 3 was operated by detecting only the presence or absence of the detection target in the region E1, but when the detection target is detected in the region E1 and the detection target is When no movement is detected (when the object to be detected is stationary), soapy water may be spouted from the soapy water spout 3. Further, in the first embodiment, the cleaning water spout 4 is operated by detecting only the presence or absence of the detection target in the region E3, but if the detection target is detected in the region E3 and the detection target is When movement is detected, cleaning water may be discharged from the cleaning water spout 4. These matters apply to the third embodiment as well.

In the second embodiment described above, the user's request is determined from the state of the detection target in the area E4, but if some movement of the detection target is detected in the area E4 (the detection target is simply When the object is moving), cleaning water is discharged from the multi-function spout 6, and when no movement of the object to be detected is detected in the area E4 (when the object is stationary), soapy water is ejected from the multi-function spout 6. It may also be discharged.

In the second embodiment described above, the warm air blowing unit 5 is operated by detecting only the presence or absence of the detection target in the region E2, but the detection target in the region E2 is not limited to the presence or absence of the detection target in the region E2. The warm air blowing section 5 may be operated by determining whether there is a request for hot air blowing based on a complex condition including the condition of the object (for example, the spread of the hand). This similarly applies to the first embodiment and the third embodiment.

In the second embodiment described above, the area sensor 110 includes five light emitting units, and in the fourth embodiment described above, the area sensor 310 includes seven light emitting units, but the number of these light emitting units may be changed as appropriate. It is possible. At this time, if priority is given to simplifying the structure, the number of light emitting units may be minimized, or if priority is given to detection accuracy, the number of light emitting units may be increased. These apply to other embodiments as well.

In the embodiments described above, the automatic washbasin device was equipped with a washing water discharging means, a soap water discharging means, and an air blowing means, but in the present invention, the automatic washbasin device includes at least a washing water discharging means. It is only necessary to include a soapy water discharge means (that is, two functional parts).
