(Embodiment 1)
The indoor dust collector in the first to seventh inventions will be described with reference to the configurations and examples shown in FIGS.

  FIG. 1 shows an example of the configuration of the air cleaning unit 100 and the floor surface cleaning unit 120 according to Embodiment 1 of the present invention. FIG. 8 shows an example of a configuration provided with the floating dust detection means of the fifth invention.

  The air cleaning unit 100 includes a suction port 101 for taking in indoor air, a removing unit 102 for removing dust and / or substances present in the air taken in from the suction port 101, and the removing unit 102. A blower outlet 103 for sending out the air processed in the room, a blower means 104 for moving air from the suction port 101 to the blower outlet 103, and an air from the suction port 101 to the blower outlet 103. The air path 105 through which the air flows, the induction signal transmitting means 106 for transmitting an induction signal for transmitting the position where the air cleaning unit 100 is disposed to the floor cleaning unit 120, and the user operating the air cleaning unit 100 And an air cleaning IF (interface) 107 for displaying the operating state of the air cleaning unit 100 and the air cleaning unit 100 And a air cleaning control unit 108 for controlling the operation of the body.

  The floor surface cleaning unit 120 includes a moving unit 121 for moving the floor surface cleaning unit 120, and a sensor 122 that detects obstacles such as walls and furniture existing around the floor surface cleaning unit when moving the floor surface cleaning unit. The cleaning means 123 for cleaning the traveling floor surface while avoiding obstacles in the room by the moving means 121 of the floor surface cleaning section 120 using the sensor 122 and the air cleaning section 100 are arranged. In order to detect the position, the user operates the guide signal receiving means 124 that receives the guide signal transmitted by the guide signal transmitting means 106 and the floor surface cleaning unit 120, or the floor surface cleaning is performed. The floor surface cleaning IF (interface) 125 for displaying the operation state of the unit 120 and the floor surface cleaning control means 126 for controlling the operation of the floor surface cleaning unit 120 are provided.

  In the fifth aspect of the invention, the air cleaning unit 800 includes floating dust detection means 809 that detects dust floating in the air in addition to the configuration of the air cleaning unit 100.

  In the example of the first embodiment, description will be made by taking as an example the contents added with the configuration for explaining the features of the present application based on the conventional air cleaner and the cleaning robot described in the background art.

  Next, the structure of the air cleaning part 100 and the air cleaning part 800 is demonstrated. The suction port 101 is an opening that takes air into the air cleaning unit 100. The removing means 102 has a function of removing dust and / or substances present in the air taken in from the suction port 101. For example, the removing means 102 is an air that is a filter medium for filtering and cleaning air. Such as a filter.

  There are many filter media with different removal performance, such as HEPA filters and ULPA filters, but the air filter may be selected as appropriate from the dust and price in the target room. Other functions that remove dust and / or substances that exist in the air, such as devices that adsorb dust that exists in the air using the force of static electricity or gas adsorption of activated carbon. It doesn't matter if it exists.

  By providing the removal means 102 immediately after the suction port 101, the floor cleaning unit 120 can clean the suction port 101 and clean the removal means 102 at the same time. Also, for example, when it is difficult to design the thickness of the removing means 102 at a place to be installed such as the suction port 101 in FIG. 4, the removing means 102 is arranged in two stages so that only relatively large dust is removed. By installing the role of the prefilter to be collected in the first stage, it can be installed in a place where it is difficult to ensure the thickness.

  The blower outlet 103 is an opening for discharging the air filtered by the removing means 102. The air blowing means 104 is capable of generating an air flow, and for example, generates air flow by rotating a fan such as a sirocco fan. The air volume can be changed by controlling the rotational speed of the fan. Any other material that can generate airflow may be used. The air path 105 is an air path through which an air flow from the suction port 101 to the air outlet 103 via the removing unit 102 and the air blowing unit 104 passes.

  The induction signal transmission means 106 transmits a signal for transmitting the position of the air cleaning unit 100 to the floor surface cleaning unit 120. For example, an element that emits light, such as a phototransistor, a photodiode, a Cds cell, or a CCD, or an element that emits ultrasonic waves. By operating these elements and transmitting specific frequency signals and specific ON / OFF timings, information can be transmitted in a non-contact manner like an infrared remote control used in general home appliances. Therefore, by receiving the signal transmitted by the guidance signal transmitting means 106, the position and direction in which the air cleaning unit 100 is installed can be detected from the intensity of the received signal and the detected direction.

  Further, since the floor cleaning unit 120 can repeatedly receive the guidance signal while moving by the moving means 121, is the approach to the air cleaning unit 100 from the distance moved and the change in the intensity of the received signal? Since it is possible to detect whether it is moving away, it is possible to approach the air cleaning unit 100 by receiving this guidance signal.

In addition, the induction signal transmitting means 106 includes a plurality of transmitting elements, for example, on the front surface and both side surfaces of the air cleaning unit 100, and changes the frequency so that the signals transmitted by the transmitting elements can be distinguished. Since it can distinguish correctly also about directions, such as whether the floor surface cleaning part 120 exists in the front of the air purifying part 100, and which side is located, it moves to the air purifying part 100 more correctly. Will be able to. In addition, any configuration may be used as long as the floor surface cleaning unit 120 can be guided to the air cleaning unit 100.

  Further, as described in the seventh invention, every time the operation time of the air cleaning unit 100 or the air cleaning unit 800 elapses for a certain time such as 24 hours, the guidance signal transmitting means 106 outputs the guidance signal, for example 24 By transmitting a predetermined time such as time, the induction signal receiving means 124 receives the induction signal at the timing when the floor cleaning unit 120 is operating, and thereby the suction port 101 of the air purification unit 100 or the air purification unit 800. And the removal means 102 can be automatically cleaned at a necessary timing according to the accumulated amount of operation time. By adopting this configuration, since the operation signal is not transmitted until a certain time has elapsed, an induction signal is not transmitted, so that unnecessary cleaning is unnecessary, which is efficient.

  An air cleaning IF (interface) 107 is an interface for displaying an operation input for the user to operate the air cleaning unit 100 and a state of ON / OFF of the operation of the air cleaning unit 100 and an air volume to the user. It is a function. For example, a switch or a touch panel is used to input an operation, and a liquid crystal screen or LED can be used to display the operation.

  The air cleaning control means 108 is composed of, for example, a CPU and a memory, and controls the operation of the blower means 104 and the timing of sending the guidance signal of the guidance signal sending means 106 and the ON / OFF control. And general control of the air cleaning unit 100 such as receiving and displaying an operation input from the air cleaning IF 107. Some CPUs have various functions such as a motor control function, a timer function, and a watchdog function, but need to be selected in accordance with the contents of the configuration. In addition, as a configuration, other controllable devices such as a one-chip microcomputer having a single CPU and memory, an FPGA, a DSP, and the like may be used.

  The floating dust detection means 809 detects dust contained in indoor air. For example, as in a particle counter used in a clean room or the like, a small amount of inhaled air is irradiated with laser light, and dust is detected. For example, the amount of dust in the air is detected by recognizing the level of scattered light. Other than that, any device that can measure the amount and level of dust in the air may be used.

  In addition, dust generation is caused by general daily activities such as walking, sitting, and laying futons, and riding on air flow from windows. The value detected by a human sensor that uses the pyroelectric effect that can be understood as an ultrasonic wave, or an ultrasonic current meter that can detect minute changes in airflow, is considered to be generating dust. It is also possible to do.

  Note that the floating dust detection means 809 often detects and detects air containing dust and the like, and if the intake port becomes clogged with dust, it becomes easy to cause problems such as failure to detect. Maintenance is required. Therefore, as described in the fifth aspect, the air cleaning unit 800 includes the floating dust detection unit 809 that detects dust floating in the air, so that the floor cleaning unit 120 includes the suction port 101 and the removal unit. By cleaning the floating dust detection means 809 as well as 102, the floating dust detection device can be configured to be cleaned at the same time.

Next, the configuration of the floor surface cleaning unit 120 will be described. For example, the moving unit 121 is configured so that two motors and two driving wheels are horizontally arranged on the left and right, and changes the rotation speed of the left and right motors according to a control signal from the floor surface cleaning control unit 126. As a result, the driving wheel operates and the floor surface cleaning unit 120 can move. In addition to the combination of motor and drive wheel, the drive unit can be moved by multiple legs such as two legs or four legs combined with a joint type actuator that combines multiple servo motors, and the motor to be used is Any device that can physically move, such as a linear motor, may be used.

  For example, the sensor 122 can measure the distance to the obstacle using a distance measuring sensor that can measure the distance to the obstacle using reflection of light or the reflection of the ultrasonic wave. It can be configured with a possible ultrasonic sensor, a switch operation when an obstacle comes into contact with the floor cleaning unit 120, or a contact sensor that acts as a bumper that detects contact by detecting a change in voltage. Is possible.

  In addition, by incorporating a plurality of these sensors in the floor cleaning unit 120, mutual detection of detection ability can be performed even in a state where detection is difficult due to the characteristics of each sensor. It becomes possible to raise. In addition, a sensor that captures an image such as a CCD camera or a sensor that uses properties such as laser, electromagnetic waves, or magnetic force can be used as a function for detecting an obstacle.

  The cleaning means 123 has a function of cleaning the vicinity of the self-propelled device. For example, a suction fan motor is provided inside the self-propelled device, and a suction port such as a vacuum cleaner is provided in the self-propelled device main body. When the self-propelled device travels, dust and dust in the traveled area can be sucked and cleaned. There are other ways to collect self-propelled devices, such as collecting dust like a mop, collecting dust with a broom-like brush, and scooping up dust and dust like a dust collector. Any configuration that can be cleaned is acceptable. Moreover, it is possible to improve cleaning performance by combining these forms.

  When the suction port 101 and the removal unit 102 of the air cleaning unit 100 are to be cleaned intensively, the cleaning unit 123 is operated, and the moving speed is set to a normal level in the vicinity of the suction port receiving the guidance signal. By making it slower than the speed of time, the cleaning time per cleaning area can be increased. In addition, when using a fan motor as a cleaning means to perform intensive cleaning, the cleaning operation can be performed with the suction force increased by increasing the rotation speed of the fan motor, or the same It is possible to focus on cleaning by operating to improve the cleaning performance over normal cleaning, such as reciprocating the place.

  The induction signal receiving unit 124 is a sensor that receives light such as a phototransistor, a photodiode, a Cds cell, or a CCD that can receive light transmitted from the induction signal transmission unit 106, for example. 106 has characteristics matching the amount of transmitted light and frequency characteristics. Further, the position of the guide signal receiving means 124 arranged in the floor surface cleaning unit 120 can be determined from the installation position of the guide signal transmitting means 106 of the air cleaning unit 100 and the moving pattern.

  For example, when the floor cleaning unit 120 searches and moves the guidance signal, if the pattern moves until the guidance signal is found along the wall, the guidance signal is arranged toward the route passing along the wall. Thus, the possibility of overlooking the induction signal can be reduced. Moreover, if it is a case where it moves at random, it can make it easy to detect the air-cleaning part 100 by transmitting a guidance signal to a wider range.

The floor surface cleaning IF (interface) 125 is an operation input for the user to operate the floor surface cleaning unit 120 and a display for informing the user of the state of the floor surface cleaning unit 120 such as ON / OFF of cleaning and a cleaning pattern. This is an interface function. For example, a switch or a touch panel is used to input an operation, and a liquid crystal screen or L is used to display an operation.
ED can be used.

  The floor surface cleaning control means 126 is composed of, for example, a CPU and a memory, and controls the drive motor of the moving means 121, receives a signal from the sensor 122, determines the presence or absence of an obstacle, and performs cleaning. Detecting the position and direction of the air cleaning unit 100 by receiving the operation control of the cleaning means 123 and the signal of the guidance signal receiving means 124, and receiving and displaying the operation input from the floor cleaning IF 125 The overall control of the floor surface cleaning unit 120 is performed.

  Some CPUs have various functions such as a motor control function, a timer function, and a watchdog function, but need to be selected in accordance with the contents of the configuration. In addition, as a configuration, other controllable devices such as a one-chip microcomputer having a single CPU and memory, an FPGA, a DSP, and the like may be used.

  About the indoor dust collector comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  FIG. 2 is a perspective view showing an example of the indoor dust collector of Embodiment 1 of the present invention. In addition, as an example of the operation flow of the indoor dust collector of the present invention, as shown in FIG. 3, the floor surface cleaning unit 120, for example, randomly cleaning for 10 minutes, after completing a predetermined cleaning operation, By using the information 122 to move along the wall of the room, the guidance signal transmitted by the guidance signal transmission unit 106 when it approaches the periphery of the air cleaning unit 100 is transmitted to the guidance signal reception unit 124. The floor cleaning unit 120 can determine that it has approached the suction port 101 and the removal unit 102, so that the moving speed of the moving unit 121 is reduced to move as indicated by an arrow in the figure. Like the path, the cleaning unit 123 performs the cleaning operation, so that the suction port 101 and the removal unit 102 of the air cleaning unit 100 can be intensively cleaned.

  FIG. 4 is a diagram illustrating an example of a side cross-sectional view of the configuration of the air cleaning unit 100. As shown in the second invention, the suction port 101 and the left-side removing means 102 of the air purifying unit 100 in FIG. 4 are provided on the floor surface so that the floor surface cleaning unit 120 can get on and clean. It is configured.

  The operation of the air purifying unit 100 is similar to a conventional air purifier in that the suction port 101 for taking in indoor air, and dust and / or substances present in the air taken from the suction port 101 are used. Through the removing means 102 to be removed, the air processed by the removing means 102 is sent out from the air outlet 103 into the room. Here, in the example of the removing unit 102 in FIG. 4, two removing units 102 are provided, and the floor surface cleaning unit 120 can clean the removing unit 102 on the left side in the drawing.

  Since the removing means 102 on the left side in the figure has a role of a pre-filter for collecting relatively large dust, the removing means 102 on the right side in the figure can be less likely to be clogged. By adopting a simple structure, it is possible to extend the period necessary for maintenance.

  Here, the area around the suction port 101 of the air cleaning unit 100 can be intensively cleaned by repeatedly cleaning the area receiving the induction signal for a predetermined time such as 5 minutes. In addition, the surroundings are cleaned not only while receiving the guidance signal, but by cleaning a predetermined area such as 1 meter around for a predetermined time such as 3 minutes after receiving the guidance signal. Various patterns can be used.

In the description of the present embodiment, the flow of performing the cleaning operation is described on the assumption that the floor cleaning unit 120 exists around the suction port 101 of the air cleaning unit 100 while the induction signal is detected. However, the movement of the moving means 121 of the floor surface cleaning unit 120 is decelerated and the cleaning means 123 is operated as described above only when the induction signal is in a condition of receiving the induction signal of a specific frequency. Thus, while specifying the location of the suction port 101 of the air cleaning unit 100, it is also possible to configure so that a signal for guiding at a different frequency is spread over a wider range.

  In addition, although the distinction by frequency is described as a method of distinguishing the induction signal, the contents of the induction signal are distinguished by a predetermined communication protocol such as an infrared remote controller used in home appliances. Any method may be used.

  By such a flow of operation, the floor cleaning unit 120 moves to the suction port 101 of the air cleaning unit 100 and automatically cleans the suction port 101 and the removing means 102, thereby maintaining the air cleaning unit 100. Therefore, it is possible to reduce time and labor for maintenance by the user. In addition, since the suction port and the removing means can always be automatically maintained, it is possible to prevent the performance of the air cleaning unit from being deteriorated due to insufficient maintenance by the user.

  Further, as shown in the third invention, by providing a slope so that the floor surface cleaning unit 120 can reach the vicinity of the suction port 101 of the air cleaning unit 100 as shown in FIG. 5, the suction port 101 is provided on the floor surface. Even if it is not provided, the maintenance can be automatically performed by cleaning the suction port 101 and the removing means 102 of the air cleaning unit 100. The slope is, for example, a rail-shaped guide that can reach the position of the suction port so that the floor surface cleaning unit 120 can clean the suction port 101 of the air cleaning unit 100, or climbing on the suction port 101. It is like a slope or staircase shape to make it easier.

  Further, the guiding signal transmitting unit 106 can efficiently clean the suction port 101 and the removing unit 102 by arranging the floor surface cleaning unit 120 to guide the suction port 101.

  Further, as shown in the fourth aspect of the present invention, as shown in FIG. 2, the air cleaner 100 is provided with an opening through which the floor surface cleaning unit 120 can ride, as shown in FIGS. Since the mouth 101 can be configured not to partially protrude from the housing of the air purifying unit 100, the suction port 101 and the suction port 101 can be installed with the same installation area as a conventional air cleaner without taking a large installation range. The removal means 102 can be configured to be automatically cleaned.

  Further, as shown in the sixth aspect of the invention, the floor cleaning control means 126 of the floor surface cleaning unit 120 detects the passage of a certain time or more, such as 3 days, for example, the suction port 101 and the removal means of the air cleaning unit 100. By being configured so as to focus on the cleaning of 102, it is possible to perform the cleaning so as to keep it clean at every interval assumed to be necessary.

  Further, as shown in the seventh invention, every time when the operating time of the air cleaning unit elapses, for example, 24 hours, a guidance signal is transmitted by the guidance signal transmission means 106 for a certain time, such as 12 hours. Thus, by receiving the induction signal by the induction signal receiving unit 124 of the floor cleaning unit 120, the intake port 101 and the removal unit 102 of the air cleaning unit 100 are cleaned, so that the intake port 101 and the removal unit 102 are changed. The maintenance can be continuously performed at the timing when the maintenance is required.
