Description

  The present invention relates to an air cleaner.

  In the air cleaner, a dirt sensor is provided in the air cleaner body. According to this air cleaner, the operation of the air cleaner body is controlled according to the measurement result of the dirt sensor. For this reason, the air around the air cleaner body can be purified.

  However, the dirt sensor detects only air dirt around the air cleaner body. For this reason, even if the air at a position away from the air cleaner body is dirty, the air cleaner body does not operate.

  On the other hand, the air cleaner which provided the wireless sensor main body in the position away from the air cleaner main body is proposed. According to this air purifier, when the wireless sensor main body detects dirt on the air, the air purifier main body changes the air volume. For this reason, the air around a wireless sensor main body can be purified (for example, refer to patent documents 1 and 2).

  As shown in FIGS. 1 and 2, an operation panel 11 is attached to the center of the intersection of the front surface and the upper surface of the front case 2. A reception unit 12 is provided on a part of the front surface of the operation panel 11. The receiving unit 12 has a function of receiving an infrared signal from the outside. The movable louver 7, the fan device 8, the dirt sensor 10, the operation panel 11, and the receiving unit 12 are connected to the control unit 13 via wiring (not shown).

Next, the wireless sensor main body will be described with reference to FIG.
FIG. 3 is a perspective view of the wireless sensor main body of the air cleaner according to Embodiment 1 of the present invention.

  In FIG. 3, reference numeral 14 denotes a wireless sensor body. The wireless sensor body 14 is formed in a substantially cubic shape. The wireless sensor main body 14 is placed at an arbitrary location in the same room away from the air cleaner main body 1.

  A dirt sensor 15 is provided on the upper surface of the wireless sensor body 14. The dirt sensor 15 has a function of detecting the environmental state of air. Specifically, the dirt sensor 15 has a function of detecting the degree of dirt such as dust and odor in the air. A display unit 16 is provided on the upper surface of the wireless sensor body 14 as necessary. The display unit 16 has a function of displaying the measurement result of the dirt sensor 15.

  A transmitter 17 is provided on the other side surface of the wireless sensor body 14. The transmission unit 17 has a function of transmitting the measurement result of the dirt sensor 15 with the infrared signal Ip. On the other side surface of the wireless sensor main body 14, a transmission unit 18 is provided at a position different from the transmission unit 17. The transmitter 18 has a function of transmitting an infrared signal Ip as a radio signal for detecting the installation direction. The transmission unit 17 and the transmission unit 18 may be the same transmission unit.

Next, the basic operation of the air cleaner body 1 will be described with reference to FIGS. 1 and 2.
When the operation switch of the operation panel 11 is turned on, the fan device 8 is driven. By this driving, the indoor air becomes a suction airflow A and is sucked from the suction port 5. The sucked air is purified by passing through the dust collection filter 9. The purified air becomes a blowout airflow B and is blown out into the room again from the blowout port 6.

At this time, the control unit 13 automatically swings the movable louver 7 left and right until the dirt sensors 10 and 15 detect the dirt. The direction of the blown airflow B is adjusted by this swing. This swing is performed intermittently at regular intervals or continuously. The movable louver 7 may be formed so as to automatically swing back and forth. The movable louver 7 may be formed so as to swing automatically by combining front and rear and left and right.

Next, a method for detecting the installation direction of the wireless sensor main body 14 will be described with reference to FIGS. 4 and 5.
FIG. 4 is a plan view showing the positional relationship between the main body of the air cleaner and the wireless sensor main body according to Embodiment 1 of the present invention. FIG. 5 is a flowchart for explaining a method by which the air cleaner in Embodiment 1 of the present invention detects the installation direction of the wireless sensor body.

  As shown in FIG. 4, the driving unit 19 is attached to the receiving unit 12. The drive means 19 is composed of a stepping motor or the like. The drive means 19 is rotationally driven. Following this drive, the receiving unit 12 moves in the horizontal direction from the position a to the position b as indicated by an arrow.

  Detection of the installation direction of the wireless sensor main body 14 is performed at an arbitrary time interval after the operation switch of the operation panel 11 is turned on. Specifically, as shown in FIG. 5, when the operation switch of the operation panel 11 is turned on, the control unit 13 of the air cleaner body 1 starts to detect the installation direction of the wireless sensor body 14 as detection means. . At this time, the transmitter 18 of the wireless sensor body 14 always emits light at an arbitrary frequency.

  In this state, the process proceeds to step S1 to perform a drive positioning operation. Specifically, the control unit 13 moves the driving unit 19 in the position a direction in FIG. Thereby, the receiver 12 is positioned at the position a.

  Then, it progresses to step S2 and the control part 13 starts a drive measurement. Specifically, the control unit 13 moves the driving unit 19 in the position b direction in FIG. 4 and scans the receiving unit 12. Thereafter, the process proceeds to step S3, and the control unit 13 determines whether or not the signal output Vi of the infrared signal Ip received by the receiving unit 12 is equal to or greater than the MIN signal threshold value Vs.

  When the signal output Vi is smaller than the MIN signal threshold value Vs, the process returns to step S2, and the control unit 13 continues the drive measurement. If the signal output Vi is equal to or greater than the MIN signal threshold Vs, the process proceeds to step S4. In step S <b> 4, the control unit 13 stores the signal output Vi together with the position information of the driving unit 19.

  Thereafter, the process proceeds to step S5, and the control unit 13 determines whether or not the drive measurement in all areas from the position a to the position b in FIG. 4 is completed. When the drive measurement of all the areas has not been completed, the process returns to step S2, and the control unit 13 continues the drive measurement. If drive measurement for all areas has been completed, the process proceeds to step S6.

  In step S6, the control unit 13 determines whether or not there is storage of the signal output Vi. If the signal output Vi is not stored, the process proceeds to step S7. In step S <b> 7, the control unit 13 determines that the wireless sensor main body 14 is not in the drive measurement detection range, and ends the detection of the installation direction of the wireless sensor main body 14. At this time, it may be displayed on the air cleaner body 1.

  On the other hand, if the signal output Vi is stored in step S6, the process proceeds to step S8. In step S <b> 8, the control unit 13 stores the position information of the driving unit 19 when the signal Vi is the largest as the installation direction of the wireless sensor main body 14. Then, it progresses to step S9 and the control part 13 complete | finishes the detection of the installation direction of the wireless sensor main body 14. FIG.

  Thus, the air cleaner body 1 recognizes the installation direction of the wireless sensor body 14. In the automatic operation mode, the air cleaner body 1 operates based on the recognition result. Hereinafter, the operation of the air cleaner body 1 in the automatic operation mode will be described.

  When the user selects the automatic operation mode on the operation panel 11, the control unit 13 of the air cleaner body 1 drives the fan device 8 so that the airflows of the suction airflow A and the blowout airflow B become weak or medium.

  The dirt sensor 10 of the air cleaner main body 1 always performs an operation of detecting the degree of air dirt around the air cleaner main body 1. The dirt sensor 15 of the wireless sensor main body 14 always performs an operation for detecting the degree of air dirt around the wireless sensor main body 14. The detection result of the dirt sensor 15 is transmitted from the transmission unit 17 to the reception unit 12 of the air cleaner body 1 as an infrared signal Ip.

  Next, the case where the dirt sensor 10 of the air cleaner body 1 detects a certain amount or more of dirt will be described. In this case, the control unit 13 of the air cleaner body 1 stops the swing of the movable louver 7. In this state, the control unit 13 of the air cleaner body 1 drives the fan device 8 so that the airflows of the suction airflow A and the blowout airflow B are increased to a high degree. This state is maintained for a certain period of time, or is maintained until the amount of dirt detected by the dirt sensor 10 becomes a predetermined value or less.

  In such a case, the swing of the movable louver 7 may be continued as long as an air flow that efficiently sucks indoor air dirt into the air cleaner body 1 is formed.

  Next, a case where the dirt sensor 15 of the wireless sensor main body 14 detects a certain amount or more of dirt will be described. In this case, an infrared signal Ip corresponding to the detection result of the dirt sensor 15 is transmitted from the transmission unit 17. The infrared signal Ip is received by the receiving unit 12 of the air cleaner body 1. Based on the infrared signal Ip, the control unit 13 of the air cleaner body 1 stops the movable louver 7 in the direction detected by the installation direction detection. At the same time, the control unit 13 of the air cleaner body 1 drives the fan device 8 so that the airflows of the suction airflow A and the blowout airflow B are increased to a high degree.

  This state is maintained for a certain period of time, or is maintained until the amount of dirt detected by the dirt sensor 15 falls below a predetermined value. Such airflow control maintains a state in which the air around the wireless sensor body 14 is intensively purified.

  In this case, it is only necessary to form an air flow that efficiently sucks dirt around the wireless sensor body 14 into the air cleaner body 1. For this reason, it is not always necessary to stop the movable louver 7.

Next, a case where both the dirt sensors 10 and 15 detect a certain amount or more of dirt will be described. In this case, the air cleaner body 1 operates by giving priority to the detection result of the dirt sensor having a large detection amount. That is, the air cleaner body 1 controls the movable louver 7 and the fan device 8 on the assumption that a certain amount or more of dirt is detected by the priority sensor. In such a case, it may be set in advance whether to give priority to the detection result of the dirt sensor 10 or the detection result of the dirt sensor 15.

  According to Embodiment 1 demonstrated above, the air cleaner main body 1 detects the installation direction of the wireless sensor main body 14 based on the infrared signal Ip. Based on the detection result, the air flow is adjusted so that the air around the installation position of the wireless sensor main body 14 moves. For this reason, the air around the wireless sensor body 14 can be purified efficiently.

  Moreover, it is not necessary to connect the air cleaner main body 1 and the wireless sensor main body 14 with an electric wire. For this reason, the freedom degree of installation of the air cleaner main body 1 and the wireless sensor main body 14 can be made high. Thereby, the dirt of the arbitrary places in the same room away from the air cleaner main body 1 can be detected.

  Moreover, the installation direction of the wireless sensor main body 14 is detected based on the position of the receiving unit 12 when the reception intensity of the infrared signal Ip is maximized. For this reason, the installation direction of the wireless sensor main body 14 can be detected with a simple configuration.

  Further, when the dirt sensor 15 of the wireless sensor body 14 detects dirt, the direction of the movable louver 7 is adjusted so that the blown airflow B from the air cleaner body 1 is directed to the vicinity of the installation position of the wireless sensor body 14. The For this reason, the air around the wireless sensor main body 14 can be purified more reliably and efficiently.

  Also, the air flow is adjusted so that the air around the installation position of the wireless sensor body 14 moves only when the dirt sensor 15 of the wireless sensor body 14 detects a certain amount or more of dirt. For this reason, power consumption can be suppressed.

Embodiment 2. FIG.
FIG. 6 is a perspective view of the main body of the air cleaner according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent, and description is abbreviate | omitted.

  The receiving unit 20 according to the second embodiment includes a plurality of receiving elements 20a to 20e. These receiving elements 20a to 20e are provided side by side in the horizontal direction. These receiving elements 20a to 20e are arranged so that the reception visual fields Ra to Re do not overlap each other.

  In the second embodiment, the control unit 13 wirelessly moves in a direction corresponding to the position of the receiving element that has received the infrared signal Ip from the transmitting unit 18 of the wireless sensor main body 14 among the receiving elements 20a to 20e of the receiving unit 20. It is determined that the sensor body 14 is installed.

According to the second embodiment described above, the installation direction of the wireless sensor main body 14 can be detected without providing the driving means 19.

Embodiment 3 FIG.
FIG. 7 is a longitudinal sectional view of a main body of an air cleaner according to Embodiment 3 of the present invention. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent, and description is abbreviate | omitted.

  The air cleaner body 1 of the third embodiment is obtained by adding a rotation mechanism 21 to the bottom surface of the air cleaner body 1 of the first embodiment. A motor 22 is disposed on the central upper surface of the rotation mechanism 21. The motor 22 supports the air cleaner body 1.

  A case where the dirt sensor 15 of the wireless sensor main body 14 detects a certain amount or more of dirt will be described. In this case, an infrared signal Ip corresponding to the detection result is transmitted from the transmission unit 17. The infrared signal Ip is received by the receiving unit 12 of the air cleaner body 1. Based on the infrared signal Ip, the control unit 13 of the air cleaner body 1 drives the motor 22 to rotate the air cleaner body 1 so that the suction port 5 faces the installation direction of the wireless sensor body 14.

  Thereafter, when the suction port 5 faces in the installation direction of the wireless sensor main body 14, the control unit 13 stops the motor 22. In this state, the control unit 13 drives the fan device 8 so that the airflows of the suction airflow A and the blowout airflow B are increased to a high level.

  This state is maintained for a certain period of time, or is maintained until the amount of dirt detected by the dirt sensor 15 falls below a predetermined value. At this time, the suction airflow A flows from the direction of the wireless sensor main body 14. That is, the suction airflow A is formed from the blowout airflow D of the wireless sensor main body 14. As a result, the air around the wireless sensor body 14 is intensively purified.

  According to the third embodiment described above, the air cleaner body 1 sucks air around the wireless sensor body 14. For this reason, the air around the wireless sensor body 14 can be purified efficiently.

Embodiment 4 FIG.
First, the air cleaner main body 1 will be described with reference to FIG.
FIG. 8 is a longitudinal sectional view of a main body of an air cleaner according to Embodiment 4 of the present invention. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent, and description is abbreviate | omitted.

  In the first embodiment, the suction panel 4 is provided on the front surface of the front case 2. On the other hand, in the fourth embodiment, the suction panel 4 is provided on the rear surface of the rear case 3.

  The air cleaner main body 1 according to the fourth embodiment includes a tank 23, a water receiving tray 24, and a humidifying means 25. The tank 23 is detachably provided on the front surface of the air cleaner body 1. The tank 23 has a function of storing water. The water receiving tray 24 is disposed below the tank 23. The water receiving tray 24 has a function of receiving water supplied from the tank 23. The humidifying means 25 is disposed between the fan device 8 and the water receiving tray 24. The humidifying means 25 includes a filter material and a frame. The filter material is formed of a material that easily absorbs water by capillary action. The lower part of the filter material is immersed in the water receiving tray 24. The frame houses and fixes the filter material.

Next, the wireless sensor main body 14 will be described with reference to FIG.
FIG. 9 is a perspective view of a wireless sensor main body of an air cleaner according to Embodiment 4 of the present invention.

  The wireless sensor body 14 includes a dirt sensor 15, a display unit 16, a transmission unit 17, a transmission unit 18, a humidity sensor 26, and a display unit 27. The humidity sensor 26 is provided on the upper surface of the wireless sensor body 14. The humidity sensor 26 has a function of measuring humidity. The display unit 27 is provided on the upper surface of the wireless sensor main body 14 as necessary. The display unit 27 has a function of displaying the measurement result of the humidity sensor 26.

Next, the basic operation of the air cleaner body 1 will be described with reference to FIG.
During operation of the air cleaner body 1, air is sucked from the suction port 5. The sucked air passes through the dust collection filter 9 and is purified. The purified air passes through the humidifying means 25 and is humidified. The humidified air is blown out into the room again from the air outlet 6.

  At this time, the humidity around the wireless sensor body 14 is measured by the humidity sensor 26. An infrared signal Ip corresponding to the measurement result is transmitted from the transmission unit 17. The infrared signal Ip is received by the receiving unit 12 of the air cleaner body 1. When the measured value corresponding to the infrared signal Ip becomes a predetermined value or less, the control unit 13 of the air cleaner body 1 stops the movable louver 7 toward the wireless sensor body 14.

  At the same time, the control unit 13 of the air cleaner body 1 drives the fan device 8 so that the airflows of the suction airflow A and the blowout airflow B are increased to a strong level. Due to this blowing airflow B, the air around the wireless sensor main body 14 is intensively humidified. This state is maintained until the measured value of the humidity sensor 26 becomes a predetermined value or more.

  According to Embodiment 4 demonstrated above, the humidification means 25 is provided in the air cleaner main body 1. FIG. For this reason, not only can air be purified, but it can also be humidified.

  Further, similarly to the first embodiment, it is not necessary to connect the air cleaner main body 1 and the wireless sensor main body 14 with an electric wire. For this reason, the freedom degree of installation of the air cleaner main body 1 and the wireless sensor main body 14 can be made high. Thereby, the humidity of the arbitrary places in the same room away from the air cleaner main body 1 is detectable.

  Further, the air flow is adjusted according to the measurement result of the humidity sensor 26. For this reason, the humidity around the wireless sensor body 14 can be increased efficiently.
