Description

  The present invention relates to a vaporizing humidifier equipped with a disk-shaped filter.

  The vaporization type humidifier is provided with a filter having water absorption and air permeability, and is absorbed by the filter by blowing air outside the device (for example, the room where the humidifier is installed) to the absorbed filter. The water containing the evaporated water (that is, humidified air) is blown to the outside of the apparatus (see Patent Documents 1 to 7).

  In general, a filter uses a filter main body having water absorption and air permeability and a frame body that holds the filter main body, and is formed in a rectangular shape, a cylindrical shape, a disc shape, etc., and the filter itself is submerged. Absorb water or absorb water by spraying the filter. Further, the filter may be rotatably provided in order to efficiently absorb water in the entire filter and / or to switch between a flooded state and a non-flooded state.

  Below, in order to absorb water efficiently with the whole filter, the humidification apparatus which rotates a disk shaped filter to the circumferential direction is demonstrated.

  The humidifier includes a water tank that stores water, and the filter of the humidifier is configured to be rotatable in the circumferential direction in a state in which a part of the outer peripheral portion is immersed in the water tank and arranged in a vertical posture. By rotating in the circumferential direction, the outer peripheral portion of the filter is continuously submerged in the circumferential direction, and water is sucked up from the outer peripheral portion to the central portion, so that water spreads throughout the filter. Furthermore, when the blower blows air to one side of the filter that has absorbed water, the air that has passed through the filter absorbs moisture, and the absorbed air is blown to the outside of the apparatus.

In a conventional humidifier, in order to adjust the amount of air to be humidified (hereinafter referred to as humidification amount), the amount of air passing through the filter (that is, the amount of air blown to the filter) is increased or decreased. For example, when the rotational speed of the fan motor of the blower is increased (or decreased) to increase (or decrease) the amount of air flow, the amount of humidification with respect to air increases (or decreases).

Configured to adjust the amount).

  The CPU 10 is a control center of the humidifying device 1, and includes an ROM 11, a RAM 12, an EEPROM 13, a display unit 14, an operation unit 15, a humidity sensor 16, a filter motor control unit 30 of the rotation drive mechanism 3, via an internal bus, a signal line, and the like. The fan motor control unit 50 of the blower 5 and the rotation sensor 6 are connected. The CPU 10 uses the RAM 12 as a work area, controls each part of the apparatus according to the control program and data stored in the ROM 11 and the data stored in the EEPROM 13, and executes various processes.

  A humidification amount switching storage part 131 (see FIG. 4) is provided in a part of the storage area of the EEPROM 13, and a scale countermeasure storage part 132 (see FIG. 5) is provided in the other part. Is provided with a total rotation number storage unit 133.

  The casing 100 has a vertical rectangular parallelepiped shape standing on the floor, and has an intake port 101 on the back, an exhaust port 102 on the top, and an intake port 101 and an exhaust port 102. The air purification filter 17, the filter 2, the rotation drive mechanism 3, the water tank 4, and the blower 5 are provided in the middle of the ventilation path 103 from the upstream side to the downstream side of the air flow. Arranged in this order.

  The air purification filter 17 uses a filter body that is both air-permeable for dust collection and deodorization, and a synthetic resin frame that holds the filter body, and has a rectangular shape that covers the entire intake port 101. Then, the air passing through the air purification filter 17 itself is filtered to filter out fine floating dust, sand dust and the like in the air and deodorize.

  The water tank 4 is provided in the bottom part of the housing | casing 100, is the tray shape which the upper part opened, and stores the water supplied from the water supply tank which is not shown in figure. This water supply tank is configured to automatically supply water to the water tank 4 in order to maintain a predetermined water level in the water tank 4.

  The filter 2 has a disk shape with an appropriate thickness, and uses a filter main body having a honeycomb structure having water absorption and air permeability, and a synthetic resin frame that holds the filter main body. Further, the filter 2 is provided with a columnar rotation shaft portion 20 at the center position, and is arranged in a vertical posture so that a part of the outer peripheral portion of the filter 2 can be submerged in the water tank 4. Therefore, the rotating shaft part 20 is arranged in a horizontal posture. Here, the rotary shaft portion 20 is rotatably supported by a bearing provided on a support portion (not shown) that is erected on the inner surface of the bottom portion of the housing 100, and as a result, the filter 2 is centered on the rotary shaft portion 20. It is supported rotatably in the circumferential direction.

  Each of the air purification filter 17 and the filter 2 is configured such that the user can easily attach and remove the filter main body to the frame body manually.

  The rotation drive mechanism 3 includes a filter motor control unit 30, an electric filter motor 31, a rotation roller 32, and a connecting shaft unit 33. The filter motor control unit 30 is controlled by the CPU 10 and gives a control signal indicating the rotation speed [rpm] to the filter motor 31. The filter motor 31 uses a DC motor and continuously increases or decreases its rotational speed in accordance with a control signal given from the filter motor control unit 30.

  The output shaft portion of the filter motor 31 and the rotation shaft portion of the rotating roller 32 are connected via a connecting shaft portion 33, and when the filter motor 31 is operated, the rotating roller 32 is in the direction of the white arrow A3 in FIG. Rotate counterclockwise in FIG.

  The rotating roller 32 is arranged such that the peripheral surface of the rotating roller 32 is in contact with the topmost part of the outer peripheral surface of the filter 2, and the rotating shaft portion 20 and the rotating shaft portion of the rotating roller 32 are arranged in parallel to each other. ing.

  Therefore, when the rotation roller 32 is rotated by the operation of the filter motor 31, the filter 2 is rotated in the direction of arrow A2 in FIG. 1 (clockwise in FIG. 1) as the rotation roller 32 rotates.

  A rotation sensor 6 is provided for the output shaft portion of the filter motor 31. The rotation sensor 6 detects the rotation operation of the output shaft portion of the filter motor 31, and gives the detection result to the CPU 10. Based on the detection result of the rotation sensor 6, the CPU 10 counts the number of times the output shaft portion of the filter motor 31 has rotated, and stores the count result in the total rotation number storage unit 133. Here, since the number of rotations of the output shaft portion of the filter motor 31 is equal to the number of rotations of the filter 2, the number of rotations of the filter 2 (hereinafter referred to as the total number of rotations) is stored in the total rotation number storage unit 133. It will be.

  The total number of rotations of the filter 2 is reset to “0” when the filter body of the filter 2 is replaced with a new filter body (or a cleaned filter body), and this filter body is reset to the next new filter body (or cleaned). The filter body continues to increase until it is replaced.

  The blower 5 includes a sirocco fan and includes a fan motor control unit 50, an electric fan motor 51, and blades 52. The fan motor control unit 50 is controlled by the CPU 10 to give a control signal indicating the rotation speed [rpm] to the fan motor 51. The fan motor 51 uses a DC motor, and continuously increases or decreases its rotation speed according to a control signal given from the fan motor control unit 50.

  When the fan motor 51 is operated, the blades 52 are rotated, and air with low humidity is sucked from the intake port 101 and passes through the air purification filter 17 and the filter 2 in this order. At this time, the air is blown in a direction orthogonal to the air purification filter 17 and the filter 2 with respect to the air purification filter 17 and the filter 2, respectively. The blown air is first purified by passing through the air purification filter 17. Next, the purified air passes through the filter 2, whereby the water absorbed by the filter 2 is vaporized, and the vaporized water is included in the air that has passed through the filter 2 (that is, the air is humidified by water vapor). ). The air whose humidity has been increased in this manner passes through the ventilation path 103 and is discharged from the exhaust port 102 into the room where the humidifier 1 is installed.

  The humidity sensor 16 detects the humidity in the room where the humidifying device 1 is installed, and gives the detection result to the CPU 10. In the present embodiment, the CPU 10 notifies the user by displaying the detection result of the humidity sensor 16 (that is, indoor humidity) on the display unit 14.

  The display unit 14 is controlled by the CPU 10 to display, for example, the operating state of the humidifying device 1, the indoor humidity, and the like, and the operation unit 15 includes various function keys using hard keys. In the present embodiment, the user of the humidifying device 1 operates the operation unit 15 while looking at the display unit 14 to give various operation commands to the humidifying device 1, and sets the humidification amount and the air blowing amount. Note that, for example, the CPU 10 may automatically set the humidification amount and the blowing amount according to the detection result of the humidity sensor 16.

  The function keys provided in the operation unit 15 are, for example, a power key 150, a humidification start key 151, a ventilation start key 152, a stop key 153, a humidification amount switching key 154, a ventilation amount switching key 155, and a reset key 156. Operates the power key 150 when the humidifier 1 is turned on / off.

  In addition, the user operates the humidification start key 151 when both the humidification and the air purification are executed by the humidifier 1, and operates the air blowing start key 152 when only the air purification is executed, so that the humidification and air purification being executed are performed. When the key is paused, the stop key 153 is operated. Furthermore, the user operates the humidification amount switching key 154 to switch the humidification amount to three levels (humidification amount “large”, humidification amount “medium”, and humidification amount “small”), and the blast amount is set to two levels (feeding). When switching between the “air volume“ large ”and the air volume“ small ”), the air volume switch key 155 is operated, the filter 2 is replaced, and then the reset key 156 is operated.

  Each time the power key 150 is operated, the CPU 10 alternately accepts a power-on command / off command, and when accepting the on-command, distributes power supplied from a power supply circuit (not shown) to the maximum necessary parts of the device. Enabling humidification and air purification. On the other hand, when the off command is received, the CPU 10 distributes the power supplied from the power supply circuit to the minimum necessary units (for example, only the CPU 10 itself) and waits until the on command is received.

  When the humidification start key 151 is operated, the CPU 10 operates the filter motor 31 and the fan motor 51 via the filter motor control unit 30 and the fan motor 51, respectively, and performs humidification and air purification. On the other hand, when the blow start key 152 is operated, the CPU 10 operates the fan motor 51 only via the fan motor 51 to perform air purification.

  When the stop key 153 is operated, the CPU 10 temporarily stops the filter motor 31 and the fan motor 51 via the filter motor control unit 30 and the fan motor 51, respectively. In this case, humidification and air purification are not performed.

  When the reset key 156 is operated, the CPU 10 resets the value of the total number of rotations stored in the total number of rotations storage unit 133 to “0”.

  Each time the humidification amount switching key 154 is operated, the CPU 10 repeatedly receives a humidification amount change command indicating any one of the humidification amount “large”, the humidification amount “medium”, and the humidification amount “small” in this order. Further, every time the air flow rate switching key 155 is operated, the CPU 10 alternately receives air flow rate change commands indicating the air flow rate “large” or the air flow rate “small”. Further, the CPU 10 causes the EEPROM 13 to store the humidification amount indicated by the received humidification amount change command and the air supply amount indicated by the received airflow change command.

  Furthermore, the default humidification amount and the blowing amount are stored in the ROM 11. If the humidification amount and / or the blowing amount are not stored in the EEPROM 13, the default humidification amount and / or the sending amount stored in the ROM 11 is stored. The air volume is stored in the EEPROM 13.

  In the following, storing the humidification amount and / or the blowing amount in the EEPROM 13 is referred to as setting the humidifying amount and / or the blowing amount.

  As shown in FIG. 4, the humidification amount switching storage unit 131 stores a combination of the rotation speed of the filter motor 31 and the rotation speed of the fan motor 51. Here, the case where air purification and humidification are performed simultaneously will be described.

  The filter motor 31 operates at any one of the first filter rotational speed Fi1 [rpm] and the second filter rotational speed Fi2 [rpm], and Fi1> Fi2 (Fi1 and Fi2 are natural numbers). Therefore, when the filter motor 31 is operating at the first filter rotational speed Fi1, the rotational speed of the filter 2 is increased compared to when the filter motor 31 is operating at the second filter rotational speed Fi2. For this reason, a part of the outer peripheral portion of the filter 2 that has been submerged moves into the air, dries, and the speed until it is submerged again increases, and the water content of the filter 2 increases. As a result, the humidification amount increases.

  On the other hand, the fan motor 51 operates at any one of the first fan rotational speed Fa1 [rpm] and the second fan rotational speed Fa2 [rpm], and Fa1> Fa2 (where Fa1 and Fa2 are natural numbers). Therefore, when the fan motor 51 is operating at the first fan rotational speed Fa1, the rotational speed of the blades 52 is increased and the air flow rate is greater than when the fan motor 51 is operating at the second fan rotational speed Fa2. As a result, the amount of air that passes through the filter 2 increases, and the amount of humidification also increases.

  Accordingly, when the filter motor 31 operates at the first filter rotational speed Fi1 (or the second filter rotational speed Fi2), and the fan motor 51 operates at the first fan rotational speed Fa1 (or the second fan rotational speed Fa2). Since the rotational speed of the filter 2 and the rotational speed of the blade 52 both increase (or decrease), the humidification amount becomes “large” (or the humidification amount “small”). On the other hand, when the filter motor 31 operates at the first filter rotation speed Fi1 (or the second filter rotation speed Fi2), and the fan motor 51 operates at the second fan rotation speed Fa2 (or the first fan rotation speed Fa1). Is one of the number of rotations of the filter 2 and the number of rotations of the blades 52 and the other is decreased, so that the humidification amount becomes “medium”.

  In order to increase or decrease the humidification amount while keeping the air flow constant, the rotation speed of the fan motor 51 is fixed at the first fan rotation speed Fa1 (or the second fan rotation speed Fa2), and the rotation speed of the filter motor 31 is changed to the first rotation speed. What is necessary is just to switch to 1 filter rotation speed Fi1 or 2nd filter rotation speed Fi2. As a result, the humidification amount “large” and the humidification amount “medium” (or the humidification amount “medium” and the humidification amount “small”) can be switched (see the arrows in FIG. 4).

  On the other hand, when it is desired to increase or decrease the air flow rate while keeping the humidification amount constant, the rotation speed of the filter motor 31 may be decreased (or increased) as the rotation speed of the fan motor 51 increases (or decreases) ( (See white arrow in FIG. 4).

  If the configuration is such that the rotational speed of the fan motor 51 is controlled to switch the rotational speed of the blades 52 of the blower 5 to two stages, the humidification amount can be switched to only two stages, and the air flow rate is constant. You cannot change the amount of humidification. However, by controlling the filter motor 31 and switching the rotation speed of the filter 2 to two stages, the humidification amount can be switched to three stages, and the humidification amount can be changed with a constant air flow rate. . That is, the humidifier 1 has a higher degree of freedom in adjusting the humidifying capacity than the conventional humidifier.

  By the way, when only air purification is performed and humidification is not performed, the rotational speed of the filter motor 31 may be kept constant at “0”. However, at this time, it is desirable to prevent the filter 2 (at least the filter body of the filter 2) from being submerged. Even when neither air purification nor humidification is performed, it is desirable to prevent at least the filter body of the filter 2 from being submerged.

  In the present embodiment, the humidification amount is switched to three stages by switching the rotation speed of each motor to two stages. However, the present invention is not limited to this, and the humidification amount is divided into four stages (for example, the humidification amount “maximum”, “Large”, “Small”, “Minimum”), or a configuration in which the amount of humidification is further switched in multiple stages by switching the rotation speed of each motor to three or more stages.

  Here, specific values of the first filter rotation speed Fi1 and the second filter rotation speed Fi2 of the filter motor 31 are stored in the scale countermeasure storage unit 132 in accordance with the total rotation number [times] of the filter 2. It is changed according to a table as shown in FIG.

  When A, B, C,... Are natural numbers of A <B <C <..., the scale countermeasure storage unit 132 sets the first filter rotation speed Fi1 to A1 [rpm when the total number of rotations is equal to or less than A [times]. The data is stored in advance (for example, at the time of factory shipment) so that the second filter rotation speed Fi2 is A2 [rpm] (where A1 and A2 are natural numbers of A1> A2). In the scale countermeasure storage unit 132, when the total number of rotations is equal to or less than B [times], the first filter rotation number Fi1 is B1 [rpm], and the second filter rotation number Fi2 is B2 [rpm] (B1 and B2 are B1> B2, B1> A1, B2> A2 (natural number), data is stored in advance. That is, as the total number of rotations of the filter 2 increases, the values of the first filter rotation number Fi1 and the second filter rotation number Fi2 of the filter motor 31 also increase.

  The increase in the total number of rotations of the filter 2 corresponds to the length of use time of the filter 2, and the length of use time of the filter 2 corresponds to an increase in the amount of scale attached to the filter 2. In addition, when the amount of scale attached to the filter 2 increases, the water absorption of the filter 2 decreases, so that the water content of the filter 2 decreases when the rotation speed of the filter 2 is constant. In order to eliminate such inconvenience, the water content of the filter 2 is maintained by increasing the rotation speed of the filter 2 (specifically, the rotation speed of the filter motor 31) in accordance with an increase in the amount of scale.

  As a result, the humidification function does not deteriorate even when the filter 2 is used for a long time. That is, since the humidifier 1 automatically and appropriately responds to the aging of the filter 2, the number of times the user replaces the filter 2 is reduced, and the convenience for the user is improved.

  However, since the increase in the amount of attached scale is moderate, it is desirable that the increase in the rotation speed of the filter 2 is also moderate.

  If the total number of rotations of the filter 2 exceeds a predetermined value, it is considered that even if the number of rotations of the filter motor 31 is increased, a decrease in the water content of the filter 2 due to an increase in the amount of scale cannot be offset. And prompting the user to replace (or clean) the filter 2 (specifically, for example, a lamp for notifying that it is time to replace the filter 2 is turned on. It is desirable to output a predetermined melody, message, etc.).

  Further, the table is not limited to the table as shown in FIG. 5, and mathematical expressions for obtaining the values of the first filter rotational speed Fi1 and the second filter rotational speed Fi2 using the total number of rotations of the filter 2 are stored in the ROM 11 or the EEPROM 13. Also good.

  Below, the case where humidification and air purification are performed simultaneously is demonstrated. For this reason, the user operates the humidification start key 151 after turning on the power key 150.

  FIG. 6 is a flowchart showing the procedure of the humidification amount control process executed by the CPU of the humidifying apparatus according to Embodiment 1 of the present invention. In the humidification amount control process, the power is turned on when the power key 150 is operated. It is executed when it is done.

  The CPU 10 determines whether or not the humidification start key 151 has been operated (S11), and if it has not been operated (NO in S11), the process of S11 is repeatedly executed.

  When the humidification start key 151 is operated (YES in S11), the CPU 10 reads the total rotation number stored in the total rotation number storage unit 133 (S12), and then scales the combination of the rotation numbers corresponding to the read value. A combination of the rotation speeds read out from the countermeasure storage unit 132 and read out is set as a combination of the first filter rotation speed Fi1 and the second filter rotation speed Fi2 (S13). Specifically, if the value x read in S12 is A <x ≦ B, the CPU 10 reads out the rotation speed combinations B1 and B2, and the first filter rotation speed Fi1 = B1 and the second filter rotation speed Fi2. = B2 is set.

  After the completion of the processing of S13, the CPU 10 reads the set humidification amount from the EEPROM 13 (S14), reads the combination of the rotation speeds corresponding to the read humidification amount from the humidification amount switching storage unit 131, and reads the read rotation. A combination of numbers is determined as a combination of the rotational speeds of the filter motor 31 and the fan motor 51 (S15). Specifically, when the data read in S14 is the humidification amount “medium”, the rotation speed of the filter motor 31 is set as the first filter rotation speed Fi1, and the rotation speed of the fan motor 51 is set as the second fan rotation speed Fa2. .

  Note that the combination of Fi2 and Fa1 may be used instead of the combination of Fi1 and Fa2, but in this combination, the noise caused by the rotation of each motor does not change much compared to the combination of Fi1 and Fa2. The amount of noise caused by the passage of air through the filter 2, the intake port 101, the exhaust port 102, the ventilation path 103, and the like is considered to increase by the amount of air flow (and hence the blowing speed).

  After completion of the processing of S15, the CPU 10 controls the filter motor control unit 30 and the fan motor control unit 50 based on the rotation speed determined in S15, so that the filter motor 31 and the fan motor 51 are rotated at the rotation speed determined in S15. Each is operated (S16). Next, the CPU 10 starts counting the total number of rotations of the filter motor 31 based on the detection result of the rotation sensor 6 (S17). The count of the total number of rotations is continuously executed until the count ends in S24 described later.

  Further, the CPU 10 determines whether or not the humidification amount switching key 154 has been operated to accept a humidification amount change command (S18), and if the humidification amount switching key 154 has not been operated (NO in S18), the blower amount switching key. It is determined whether 155 has been operated and an air volume change command has been received (S19).

  When the humidification amount switching key 154 is operated and a humidification amount change command is received (YES in S18), or when the ventilation amount switch key 155 is operated and a ventilation amount change command is received (YES in S19), the CPU 10 The humidification amount indicated by the received humidification amount change command or the airflow rate indicated by the received airflow change command is set, and the set humidification amount or the combination of the rotational speeds corresponding to the airflow amount is read from the humidification amount switching storage unit 131. The combination of the read rotation speeds is determined as the combination of the rotation speeds of the filter motor 31 and the fan motor 51 (S20).

  After completing the process of S20, the CPU 10 controls the filter motor control unit 30 and the fan motor control unit 50 based on the rotation speed set in S20, so that the filter motor 31 and the fan motor 51 are rotated at the rotation speed determined in S20. Each is operated (S21), and the process returns to S18.

  When the air volume switching key 155 is not operated (NO in S19), the CPU 10 determines whether the power is turned off by operating the power key 150 (S22), and the power key 150 is operated. If not (NO in S22), the process returns to S18.

  When the power is turned off by operating the power key 150 (YES in S22), the CPU 10 controls each of the filter motor control unit 30 and the fan motor control unit 50 to control each of the filter motor 31 and the fan motor 51. Stop (S23), finish counting the total number of rotations of the filter motor 31 (S24), and end the humidification amount control process.

  The CPU 10 in such a humidification amount control process functions as a humidification control unit and a rotation control unit by controlling the filter motor control unit 30 and the fan motor control unit 50, respectively. Further, the CPU 10 receives the detection result of the rotation sensor 6 and functions as a counting unit.

  Since the humidifier 1 as described above controls the water content of the filter 2 and the air flow rate of the blower 5, the humidification amount and the air flow rate are appropriately adjusted, and air conditioning desired by the user is obtained. If the rotational speed of only the filter motor 31 or the fan motor 51 is increased or decreased, the rotational speed becomes an extremely high (or low) value, and unnecessary resonance may occur. By increasing or decreasing the water content of both, it becomes possible not to use the rotational speed at which resonance occurs.

  In addition, even when the humidification amount is increased, the increase in noise due to the increase in the unnecessary air flow rate is suppressed, and even when the humidification amount is decreased, the decrease in the air purification capacity due to the decrease in the unnecessary air flow rate is prevented. Is done.

  Moreover, by increasing the rotation speed of the filter 2, the water content of the filter 2 is maintained regardless of an increase in the amount of adhesion of the scale.

  In addition, the structure of the humidification apparatus 1 is not limited to the structure of this Embodiment. For example, the air blown by the blower 5 may be heated on the upstream side of the filter 2 to promote further transpiration in the filter 2, and an ion generating element may be disposed near the exhaust port to generate the air. The positive ions and negative ions may be added to the exhausted air.

  Further, the present invention is not limited to the configuration in which the motors are continuously rotated, and a configuration in which the motors are intermittently rotated may be used. In such a configuration, each motor is constituted by an inexpensive AC motor instead of a DC motor, and the ratio of the time for operating the motor to the time for stopping the motor is changed to thereby change the average rotational speed of the motor (that is, the time of the motor). Change the average value of the number of revolutions that changes over time. In this case, the average water content of the filter 2 and the average air flow rate of the blower 5 (that is, the water content and the average value of the air flow rate that change over time) are controlled without increasing the cost of the humidifier 1. Thus, the humidification amount can be adjusted in multiple stages.

  By the way, in this Embodiment, since each of the filter motor 31 and the fan motor 51 rotates continuously with the rotation speed determined by CPU10, this rotation speed and average rotation speed are equal.

Embodiment 2. FIG.
FIG. 7 is a side view showing the internal configuration of the humidifying device according to Embodiment 2 of the present invention, and FIG. 8 is a rear view showing the configurations of the filter, water tank, and water supply tank provided in the humidifying device. FIG. 9 is a plan view showing the configuration of the filter and water tank provided in the humidifier, and FIG. 10 is a plan view showing the vicinity of the scattering prevention part provided in the humidifier.

  FIG. 11 is a rear view showing the vicinity of the water passage hole formed in the partition portion of the humidifier, and FIG. 12 is a view of the passage formed in the partition portion of the humidifier not provided with the scattering prevention portion. It is a rear view which shows the water hole vicinity.

  In the figure, reference numeral 1 denotes a humidifier, and the humidifier 1 according to the present embodiment shown in FIGS. 7 to 11 has the same configuration as the humidifier 1 according to the first embodiment. Has been added. Other parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIGS. 7-12, the water supply tank 7 which supplies water to the water tank 4 is attached to the left side part of the housing | casing 100 so that attachment or detachment is possible.

  The inside of the housing 100 is composed of plate-shaped partition portions 8 and 81 made of synthetic resin and a partition wall (not shown) in the housing 100, and the air purification filter 17, the filter 2, the rotation drive mechanism 3, the water tank 4 made of synthetic resin, And the side of the ventilation path 103 where the blower 5 is arranged (the right side of the partition parts 8 and 81 in FIGS. 8, 11 and 12 and the left side of the partition parts 8 and 81 in FIGS. 9 and 10), the water tank 4 and Partitioned on the tank arrangement side where the water supply tank 7 is disposed (the left side of the partition parts 8 and 81 in FIGS. 8, 11 and 12 and the right side of the partition parts 8 and 81 in FIGS. 9 and 10). . For this reason, the inflow / outflow of air hardly occurs between the tank arrangement side and the ventilation path 103 side while avoiding the partition portions 8 and 81.

  The water tank 4 has a water storage part 4a on the side of the ventilation path 103 that is elongated in the left-right direction and is distributed from the center part of the housing 100 to the right side part by a partition part 8 that is integrally provided on the bottom surface 40 of the water tank 4. And a water storage section 4b on the tank arrangement side disposed on the left side of the casing 100.

  The water supply tank 7 is fixed to the housing 100 in an inverted state with the opening 7a facing the water storage part 4b of the water tank 4, and is maintained with respect to the water storage part 4b of the water tank 4 in order to maintain a predetermined water level W1 in the water tank 4. It is configured to supply water automatically. Here, the water level W1 is a position where the filter 2 is sufficiently submerged and is sufficiently lower than each side surface of the water tank 4. However, the front and back side surfaces 41 and 42 (that is, the two side surfaces 41 and 42 parallel to the filter 3) of the water storage section 4a of the water tank 4 have an appropriate height that does not obstruct the air passing through the filter 2. Have.

  The water storage part 4a and the water storage part 4b are connected by the water flow hole 8a formed in the lowest part of the partition part 8. FIG. The lowermost end of the water passage hole 8a is arranged on the same plane of the bottom surface 40 of the water storage section 4a, and the upper end of the water passage hole 8a is disposed at a position sufficiently lower than the water level W1, and is supplied to the water storage section 4b. Water is supplied from the water storage section 4b to the water storage section 4a through the water passage hole 8a. Further, if the water level of the water tank 4 is higher than the upper end of the water hole 8a (that is, if the water hole 8a is completely submerged), the tank arrangement side and the air flow through the water hole 8a. There is no inflow or outflow of air between the path 103 side.

  When the blower 5 is operated, air is sucked from the air inlet 101, and the sucked air is first purified by passing through the air purification filter 17 formed by laminating the deodorizing filter 171 and the dust collecting filter 172, Then, it is humidified by passing through the filter 2. The air purified and humidified in this way passes through the ventilation path 103 and is discharged from the exhaust port 102 to the room where the humidifier 1 is installed.

  At this time, the pressure on the ventilation path 103 side inside the housing 100 is lower than the pressure on the tank arrangement side. The large / small pressure difference between the ventilation path 103 side and the tank arrangement side is proportional to the rotational speed of the fan motor 51.

  If the partition portions 8 and 81 are not provided, air that has not passed through the air purification filter 17 easily flows from the tank arrangement side to the ventilation path 103 side, so that the air purification efficiency deteriorates. That is, the partition parts 8 and 81 improve the air purification efficiency.

  Next, with respect to the humidifier shown in FIG. 12 (that is, the humidifier not provided with the scattering prevention unit 9), the water level of the water tank 4 is lowered due to some circumstances (for example, lack of water supply from the water supply tank 7) during the operation of the blower 5. However, the water droplet scattering phenomenon that occurs when the water level W2 that is the same as or slightly lower than the upper end of the water passage hole 8a is reached will be described.

  When a part of the water passage hole 8a that has been submerged is exposed to the air, a wind B that is blown from the tank arrangement side to the ventilation path 103 side is generated due to a pressure difference between the tank arrangement side and the ventilation path 103 side. This wind B has a high wind speed because the exposed portion of the water passage hole 8a in the air is narrow. As a result, the water stored in the water tank 4 is wound up by the wind B, and water droplets are scattered.

  At least a part of the scattered water droplets moves to the outside of the water tank 4 beyond the side surfaces 41 and 42, and is disposed between the outer surface of the water tank 4, the bottom surface of the housing 100, and the water tank 4 and the blower 5 (not shown). It adheres to an object outside the water tank 4 such as a plate. Further, when the amount of splashed water droplets is large, water may leak to the outside of the housing 100 along the bottom surface of the housing 100. Furthermore, when the water adhering to the object outside the water tank 4 is dried, impurities contained in the water adhere to the object outside the water tank 4.

  Water and impurities adhering to an object outside the water tank 4 must be wiped by the user of the humidifying device 1, and the convenience for the user is deteriorated. Further, the water leaked to the outside of the housing 100 wets the floor on which the humidifier 1 is placed.

  Therefore, it is necessary to prevent water droplets from scattering outside the water tank 4.

  As shown in FIGS. 8 to 11, the humidifying device 1 according to the present embodiment has a structure from the water hole 8 a to the opening of the water tank 4 on the side of the air flow path 103 in order to prevent water droplets from scattering outside the water tank 4. In more detail, the scattering prevention unit 9 is disposed at a position that shields the water droplet scattering path (that is, the wind B ventilation path) that is to be scattered along with the wind B.

  The scattering prevention part 9 has a flat plate shape having water repellency, and is attached to the side of the ventilation path 103 of the partition part 8 so as to be inclined like a roof gutter. More specifically, the anti-scattering portion 9 has a flat plate shape in which the front-rear direction is disposed between the side surfaces 41, 42 of the water tank 4, and is gradually lowered from the proximal end side to the distal end side in the left-right direction. It is arranged in a direction that is inclined with respect to the bottom surface 40 of the water tank 4. The base end side of the scattering prevention part 9 is arranged at a position sufficiently lower than the upper ends of the side surfaces 41 and 42, and the distal end side of the scattering prevention part 9 is arranged at a position sufficiently higher than the opening upper end of the water passage hole 8a. ing. In addition, the scattering prevention unit 9 has the tip side as close as possible to the filter 2 and is separated from the filter 2 by an appropriate length. It is arranged.

  As shown in FIG. 11, when the water level of the water tank 4 reaches the water level W2 and the wind B blown from the tank arrangement side to the ventilation path 103 side is generated, the water stored in the water tank 4 is rolled up by the wind B, Water droplets are scattered.

  However, the scattered water droplets collide with the lower surface of the scattering prevention unit 9 and fall into the water tank 4 or adhere to the scattering prevention unit 9. Further, the water droplets adhering to the scattering prevention unit 9 fall into the water tank 4 through the scattering prevention unit 9.

  Here, the scattering prevention unit 9 blocks the space between the side surfaces 41 and 42, and the filter 2 is disposed above the front end side of the scattering prevention unit 9, so that water droplets avoid the scattering prevention unit 9. Even if it avoids, it will collide with the filter 2. Therefore, water droplets are prevented from scattering outside the water tank 4.

  In addition, the scattering prevention unit 9 does not hinder the rotation of the filter 2 because it is spaced apart from the filter 2. Furthermore, since it is distribute | arranged above the opening upper end of the water flow hole 8a, the scattering prevention part 9 does not inhibit the water flow through the water flow hole 8a. Here, when the height of the tip of the splash prevention part 9 is equal to the height of the upper end of the water passage hole 8a, strong wind is generated between the splash prevention part 9 and the water surface of the water level W2, and water droplets can be scattered. Therefore, it is desirable that the height of the tip of the scattering prevention part 9 is sufficiently higher than the height of the upper end of the water passage hole 8a.

  In addition, the scattering prevention part 9 may be distribute | arranged in parallel with the bottom face 40 of the water tank 4, and may be integrally formed in the partition part 8 or the side surfaces 41 and 42. FIG. Moreover, the structure which the protrusion prevention part 9 protrudes from the bottom face 40 may be sufficient. Furthermore, the scattering prevention part 9 may be formed with the material (for example, sponge) which has water absorption. In this case, the water droplets colliding with the splash prevention unit 9 are absorbed by the splash prevention unit 9 and dropped into the water tank when the amount of water absorption increases, so that it is prevented from splashing outside the water tank 4.

  Although the scattering prevention part 9 of this Embodiment is distribute | arranged to the position higher than the water level W1, the structure by which some or all of the scattering prevention part 9 is distribute | arranged to the position lower than the water level W1 may be sufficient.

  Moreover, the scattering prevention part formed with the object which has air permeability and water permeability like a sponge is provided with the scattering prevention part 9, or without providing the scattering prevention part 9, and the ventilation path 103 of the water flow hole 8a. The side opening may be closed. In this case, since the speed of the wind B that has passed through the scattering prevention unit is reduced, the scattering of water droplets is suppressed, and even if the water droplets are slightly scattered near the water surface, the scattered water droplets are absorbed by the scattering prevention unit. Therefore, water droplets are prevented from scattering outside the water tank 4. Moreover, the splash prevention part hardly inhibits the water flow through the water flow hole 8a.

  In the humidifying device 1 as described above, water droplets scattered outside the water tank 4 beyond the side surfaces 41 and 42 adhere to an object outside the water tank 4, and the scattered water droplets flow out to the outside of the housing 100. Impurities contained in the water droplets can be prevented from adhering to an object outside the water tank 4, so that the convenience of the user can be improved, and the appearance of the humidifier 1 is impaired by the adhering substances. Can be prevented, and the floor on which the humidifying device 1 is installed can be prevented from getting wet.

  By the way, the phenomenon in which water droplets scatter to the outside of the water tank 4 occurs remarkably in a humidifier equipped with a rotating disk-shaped filter 2. This is because the filter 2 needs to be sufficiently separated from the inner surface of the water tank 4 for smooth rotation of the filter 2. In a humidifier equipped with a rectangular plate-shaped filter that does not rotate, such as the humidifier disclosed in Patent Document 7, it is possible to prevent water droplets from scattering by closing the water passage hole with this filter.

  However, if the user of the humidifying device wants to increase (or decrease) the humidification amount without changing the airflow rate, increase (or decrease) the airflow rate to increase (or decrease) the humidification amount. There is a problem that the air conditioning desired by the user cannot be obtained.

  Further, when the air flow rate is increased in order to increase the humidification amount, there is a problem that the noise of the air passing through the filter, the noise of the fan motor of the blower, and the like increase. Furthermore, if the humidifier is also equipped with an air purification filter having functions such as dust collection and deodorization, reducing the air flow to reduce the humidification amount will reduce the amount of air passing through the air purification filter, There is a problem that the purification efficiency of air is lowered.

  The present invention has been made to solve such a problem, and its main purpose is to control the water content of the filter and the air flow rate of the blower according to the amount of air to be humidified. Accordingly, an object of the present invention is to provide a humidifier that can adjust the humidification amount without depending only on the increase / decrease in the blower amount of the blower.

  Another object of the present invention is to control the average rotational speed of the filter motor that rotates the filter and the average rotational speed of the fan motor that rotates the blades of the blower according to the amount of air to be humidified. Accordingly, an object of the present invention is to provide a humidifier capable of adjusting the humidification amount by increasing / decreasing the average rotational speed of two types of motors.

  Another object of the present invention is to increase the average rotational speed of the filter according to the usage time of the filter, so that even a filter having a scale attached and having reduced water absorption can be sufficiently absorbed. It is to provide a humidifier.

  Another object of the present invention is to provide a humidifier that can easily determine the filter usage time by increasing the average number of rotations of the filter in accordance with an increase in the number of rotations of the filter. It is in.

  Another object of the present invention is to disperse water droplets in order to prevent splashing to the outside of the aquarium because the splash prevention unit made of a material having water repellency or water absorption is arranged in the water droplet splashing path. The object is to provide a humidifier that can be returned or sucked.

  Still another object of the present invention is to provide a plate-shaped splash prevention portion arranged between both side surfaces of the water tank to prevent the splashing of water droplets to the outside of the water tank. An object of the present invention is to provide a humidifier capable of preventing the water droplets from being scattered with a simple configuration.

  A humidifier according to the present invention includes a disk-shaped filter having water absorption and air permeability, a rotation drive mechanism for rotating the filter in the circumferential direction, a water tank for storing water, and the filter. An amount of air to be humidified in a humidifying device in which the filter is arranged in a vertical posture and a part of the outer peripheral portion of the filter can be submerged in the water tank. It is characterized by comprising a humidification control means for controlling the water content of the filter and the air volume of the blower according to the size of the filter.

  A humidifier according to the present invention includes a disk-shaped filter having water absorption and air permeability, a rotation drive mechanism for rotating the filter in the circumferential direction, a water tank for storing water, and the filter. An amount of air to be humidified in a humidifying device in which the filter is arranged in a vertical posture and a part of the outer peripheral portion of the filter can be submerged in the water tank. Humidification control means for controlling the air flow rate of the blower according to the size of the blower, a water supply tank for supplying water to the water tank, a tank arrangement side where the water supply tank is disposed inside the water tank, and the filter A partition part that is divided into a ventilation path side where the rotation drive mechanism and the blower are arranged, and a water passage hole for supplying water from the tank arrangement side to the ventilation path side is formed, and the water flow Hole Between the opening of the water tank and the opening on the side of the ventilation path is separated from the filter by an appropriate length, and is generated due to a pressure difference between the tank arrangement side and the ventilation path side when the water level of the water tank is lowered. It is provided with the scattering prevention part which prevents scattering of the water drop to the exterior of the water tank.

  In the humidifier according to the present invention, the rotation drive mechanism has a filter motor that rotates the filter, the blower has a fan motor that rotates blades of the blower, and the humidification control means humidifies the fan. When the power amount is increased (or decreased), the average rotational speed of the filter motor and / or the fan motor is increased (or decreased).

  The humidifier according to the present invention is characterized in that one side of the anti-scattering part is arranged on the partition part and the other side of the anti-scattering part is arranged below the filter.

  The humidifier according to the present invention is further characterized by further comprising a rotation control means for increasing the average rotational speed of the filter in accordance with the usage time of the filter.

  The humidifying device according to the present invention is characterized in that the scattering prevention part is inclined in a direction approaching the bottom surface of the water tank from the partitioning part side to the filter side.

  The humidifying device according to the present invention further includes counting means for counting the number of times the filter has rotated, and the rotation control means increases the average number of rotations as the number of times counted by the counting means increases. It is characterized by that.

  The humidifying device according to the present invention is characterized in that the scattering prevention unit is disposed over one surface and the other surface of the water tank facing the filter.

  The humidifying device according to the present invention includes a water supply tank that supplies water to the water tank, a tank arrangement side in which the water supply tank is disposed inside the water tank, the filter, the rotation drive mechanism, and the blower. A partition section that is divided into a ventilation path side that is arranged, and has a water passage hole for supplying water from the tank arrangement side to the ventilation path side; and an opening on the ventilation path side of the water tank from the water passage hole The water droplets are scattered to the outside of the water tank generated by a difference in pressure between the tank arrangement side and the ventilation path side when the water level of the water tank is lowered. It is further provided with the scattering prevention part which prevents this.

  The humidifier according to the present invention further comprises a rotation control means for increasing an average rotational speed of the filter according to a usage time of the filter, and a counting means for counting the number of times the filter has been rotated. The means is characterized in that the average rotational speed is increased in accordance with an increase in the number of times counted by the counting means.

  The humidifying device according to the present invention is characterized in that the scattering prevention unit is made of a material having water repellency or water absorption, and is arranged at a position that shields the scattering path of the water droplets.

  In the humidifying device according to the present invention, the scattering prevention portion has a plate shape, is at a height not less than the upper end of the water passage hole and not more than the upper end of the side surface of the water tank, and is parallel to the bottom surface of the water tank or It is arranged between the two side surfaces parallel to the filter in a direction inclined with respect to the bottom surface.

  In this invention, a filter, a rotation drive mechanism, a water tank, a blower, and a humidification control means are provided, and the filter has a disk shape and has water absorption and air permeability.

  The filter is arranged in a vertical posture, and a part of the outer periphery of the filter can be submerged in a water tank for storing water. The rotation drive mechanism rotates a filter arranged in a vertical posture in the circumferential direction, and the blower blows air to the filter in a direction crossing the filter. When the blower blows air to a filter in which a part of the outer periphery is submerged, the air that has passed through the filter absorbs moisture, and the absorbed air is blown out of the apparatus.

  The humidification control means controls the water content of the filter and the blower amount of the blower according to the amount of the air to be humidified (that is, the humidification amount). When the humidification amount is very large, the humidification control means increases both the water content of the filter and the blower amount of the blower. On the other hand, when the humidification amount is very small, the humidification control means decreases both the water content of the filter and the blower amount of the blower.

  Further, the humidification amount is adjusted without changing the air flow rate by changing the water content of the filter while keeping the air flow rate of the blower constant. That is, the humidification amount desired by the user of the humidifying device and the blown amount are compatible.

  And since it is not necessary to increase the ventilation volume of a blower in order to increase the humidification amount, generation | occurrence | production of the noise accompanying the increase in ventilation volume is suppressed. Furthermore, since it is not necessary to reduce the air flow rate of the blower in order to reduce the humidification amount, a decrease in the air conditioning function accompanying the decrease in the air flow rate is prevented.

  In the present invention, the rotation drive mechanism has a filter motor that rotates the filter, and the blower has a fan motor that rotates the blades of the blower.

  The humidification control means increases (or decreases) the average rotational speed of the filter motor and / or the fan motor when the humidification amount is increased (or decreased).

  Specifically, when the average rotation speed of the filter motor is increased (or decreased), the water content of the filter increases (or decreases), and the humidification amount increases (or decreases). This is because when the average rotational speed of the filter motor increases (or decreases), the average rotational speed of the filter increases (or decreases), so that the part of the outer periphery of the filter that has been submerged moves into the air, This is because the speed of drying and re-immersion by blowing is increased (slow). On the other hand, when the average rotational speed of the fan motor is increased (or decreased), the average rotational speed of the blades of the blower is increased (or decreased), and the amount of air blown by the blower is increased (or decreased). (Or decrease).

  That is, the humidification amount can be adjusted by increasing or decreasing the average rotational speed of the two types of motors.

  Further, when the humidification amount is very large (or small), the humidification control means increases (or decreases) the average rotational speed of both the filter motor and the fan motor. For this reason, unlike the case where one of the filter motor and the fan motor is set to an extremely high (low) average rotation speed to obtain a very large (or small) humidification amount, both the filter motor and the fan motor are By setting the average rotation speed to an appropriate value, a very large (or small) humidification amount can be obtained.

  Furthermore, the humidification amount is adjusted without changing the air flow rate by increasing or decreasing the average rotation number of the filter motor while keeping the average rotation number of the fan motor constant. That is, the humidification amount desired by the user of the humidifying device and the blown amount are compatible.

  In the present invention, the rotation control means increases the average rotation speed of the filter according to the usage time of the filter. Here, the use time of the filter is, for example, a simple elapsed time from the start of use of the filter, or the total time during which the filter has been submerged.

  As the filter usage time increases, the amount of scale adhering to the filter increases, and as the amount of scale adhering to the filter increases, the water absorbency of the filter decreases. This is offset by increasing the average rotational speed of the filter and increasing the water content of the filter. That is, water can be sufficiently absorbed by a filter having a scale attached thereto and reduced water absorption.

  In addition, although it is difficult to directly detect the amount of scale attached to the filter, for example, to measure the usage time of the filter includes a timer that counts the elapsed time from when the filter is attached. Therefore, the humidifier can be easily configured.

  In the present invention, the counting means counts the number of times the filter has rotated.

  The length of use time of the filter is considered to correspond to the number of times the filter has been rotated from the start of use of the filter to the present time. Therefore, the rotation control means increases the average rotation speed of the filter in accordance with the increase in the number of times counted by the counting means, that is, the number of times the filter has rotated. That is, water can be sufficiently absorbed by a filter having a scale attached thereto and reduced water absorption.

  In addition, unlike the case where the elapsed time from when the filter is attached is simply measured using a timer, for example, the time when the filter is not rotating (that is, the time when the filter is not used) is not included in the usage time. Therefore, more accurate use time can be obtained. In addition, while not humidifying and not using a filter, it is desirable to leave the filter (at least the filter main body having water absorption) in a non-water-immersed state.

  In this invention, the water supply tank which supplies water to a water tank, the partition part in which the water flow hole is formed, and the scattering prevention part are further provided.

  A filter, a rotation drive mechanism, and a blower are arranged on the ventilation path side of the humidifier, and a water supply tank is arranged on the tank arrangement side.

  The partition part which partitions the inside of a water tank into the ventilation path side and the tank arrangement | positioning side is provided in order to prevent that the air of a tank arrangement | positioning side moves to the ventilation path side via a water tank. However, in order for the filter provided on the ventilation path side to suck up the water supplied to the tank arrangement side of the aquarium by the water supply tank, the partition is provided with water flow for supplying water from the tank arrangement side to the ventilation path side. A hole is formed.

  When the humidifier is used, the air pressure on the ventilation path side inside the device becomes lower than the air pressure on the tank arrangement side by the air blown by the blower. Usually, since the water passage hole is located below the surface of the water, the air on the tank arrangement side does not move to the air passage side through the water passage hole.

  However, if the water surface drops to a height that is the same as or slightly lower than the upper end of the water hole for some reason, the air on the tank arrangement side moves to the air passage side through the water hole.

  A scattering prevention part is arranged between the water hole and the opening on the air passage side of the water tank. For this reason, even if the air blown out from the tank arrangement side to the ventilation path side rolls up the water in the water tank, the water droplets that have been rolled up hit the splash prevention part and fall into the water tank or are absorbed by the splash prevention part, etc. It is prevented from splashing outside. Or a scattering prevention part prevents that the air which blows off from the tank arrangement | positioning side to the ventilation path side rolls up the water of a water tank.

  In the present invention, scattering prevention using a material having water repellency or water absorption at a position that shields the splashing path of water droplets to be splashed to the outside of the water tank due to the pressure difference between the tank arrangement side and the ventilation path side Department is arranged. For this reason, even if the air blown from the tank arrangement side to the ventilation path rolls up the water in the aquarium, the rolled up water droplets hit the splash-proof portion having water repellency or fall into the water tank, or in the splash-proof portion having water absorption It is prevented from being scattered outside the water tank, for example, by being absorbed.

  In this invention, the plate-shaped scattering prevention part which has water repellency or water absorption is provided.

  The scattering prevention part is arranged at a height not less than the upper end of the water hole and not more than the upper end of the water tank side surface. For this reason, the splash prevention unit does not hinder the water flow through the water passage hole, and even if the water droplets are scattered by the air blown from the tank arrangement side to the ventilation path side, the scattered water droplets do not touch the upper end of the water tank side surface. It is surely prevented from moving outside the tank.

  Furthermore, since the splash prevention part is arranged in a direction parallel to or inclined with respect to the bottom surface of the water tank, the splashed water droplets are attached (or absorbed) to the splash prevention part or in contact with the splash prevention part. Fall into the aquarium. In order to promote the drop of water droplets into the water tank, it is preferable that the scattering prevention portion is inclined.

  Furthermore, since the splash preventing part is arranged between the two water tank side faces parallel to the filter, water droplets are scattered outside the water tank through the side face of the water tank and the splash preventing part. To prevent.

  In the case of the humidifier according to the present invention, the moisture content of the filter and the blower amount of the blower are controlled, so that the humidification amount can be adjusted regardless of the increase or decrease of the blower amount with respect to the filter of the blower. Therefore, the air conditioning (humidification amount and air flow rate) desired by the user can be obtained.

  Moreover, even when the amount of humidification is increased, an increase in noise can be suppressed, and even when the amount of humidification is decreased, a decrease in the air conditioning function can be prevented.

  Furthermore, in the case of the humidifier according to the present invention, by increasing the average rotation speed of the filter, the filter can sufficiently absorb water regardless of the decrease in water absorption of the filter due to the adhesion of scale.

  In the case of the humidifying device of the present invention, the splash prevention unit with a simple configuration prevents the splash of water droplets outside the water tank. Therefore, since the scattered water droplets can be prevented from adhering to an object outside the water tank, it is possible to save time and effort for the user to wipe off the adhered water droplets. Furthermore, it is possible to prevent the water droplets adhering to the object outside the water tank from being dried and the impurities contained in the water droplets from adhering. Therefore, it is possible to prevent the inside of the humidifying device from being contaminated and impairing the aesthetic appearance by the impurities, and it is possible to save time and effort for the user to clean the adhered impurities. Furthermore, it is possible to prevent the splashed water droplets from leaking out of the apparatus.
