<< Entire configuration of the air purifier 1 >>
FIG. 1 is a perspective view showing an air cleaner 1 according to an embodiment of the present invention, FIG. 2 (a) is a front view of the air cleaner 1 according to the embodiment, and FIG. It is AA sectional view taken on the line of 2 (a). FIG. 3 is an exploded perspective view of the air cleaner 1 according to the embodiment.

  As shown in FIGS. 1 and 3, the air purifier 1 of the embodiment is covered with a main housing case 2 and a front housing case 3 which are housings, and the front housing. A front panel 4 is attached to the front surface of the case 3, and a locking portion (not shown) of the front panel 4 is elastically deformed and attached to a locked portion (not shown) of the front housing case 3. .

  Thus, since the front panel 4 is simply attached to the front case 3, the front panel 4 can be easily used for maintenance of the filter unit 5 (see FIG. 2B) of the air cleaner 1. It can be removed and attached.

  As shown in FIG. 2B, the air cleaner 1 shown in FIG. 1 has a fan motor 7 (see FIG. 2) for sucking indoor air through a clearance c between the front panel 4 and the front housing case 3. 3), a filter unit 5 for collecting and deodorizing indoor air sucked by the fan motor 7, a water tank 13 for storing water for humidifying the indoor air, and the filter unit 5 A vaporizing filter unit 15 for humidifying the air purified through the water tank 13 with water pumped from the water tank 13, a desiccant rotor 9 for dehumidifying and absorbing the moisture of the air purified through the filter unit 5, and a desiccant rotor 9. The heater 33 (see FIG. 3) for heating the air that vaporizes the absorbed moisture and the air containing the moisture absorbed and vaporized from the desiccant rotor 9 The condenser 11 (see FIG. 3) for condensing the minute and the centrifugal fan 7a of the fan motor 7 is surrounded and the gap between the centrifugal fan 7a and the outer periphery is widened toward the upper discharge port 2o to be formed and cleaned. And a spiral fan casing 8 (see FIG. 3) for discharging the generated air.

  As shown in FIGS. 1 and 2 (b), a clearance c is formed between the front housing case 3 and the front panel 4 which are the housing of the air purifier 1, and the clearance c As shown by an arrow α11 in FIG. 2 (b), dirty air in the room is sucked into the air purifier 1 and the air filtered and purified through the filter unit 5 is swirled in the fan casing 8. (See FIG. 3 and FIG. 2A), and as shown in FIG. 1, the air is discharged into the room through the discharge port 2 o opened at the top of the main housing case 2.

  Here, as shown in FIGS. 1 and 3, a flap 2t (louver), which is a lid opening / closing lid for opening and closing the discharge port 2o of the main housing case 2, is formed on the upper portion of the main housing case 2. As shown in FIG. 1, when the air cleaner 1 is operated, the flap 2t is controlled to open so that the main housing case 2 can be removed. The outlet 2o is opened, and the air cleaned by the air cleaner 1 is discharged. The flap 2t can be rotated in the range of 0 degrees (horizontal) to 90 degrees (vertical). The flap 2t may be rotatable in the range of 0 degrees (horizontal) to 85 degrees (substantially vertical). When the flap 2t is 0 degrees, the wind direction is forward, and when the flap 2t is 90 degrees or 85 degrees, the wind direction is upward.

  Further, the upper discharge port 2o portion of the main housing case 2 is divided and integrated by being fixed by a screw exposed to the outside. By removing this screw and removing the discharge port 2o, a frame (not shown) that holds the flap 2t, which is a lid opening / closing lid that opens and closes the discharge port 2o, the flap opening / closing motor 61, the drive link 62, and the driven link 63 is shown. The unit can be easily removed and attached. With this structure, the motor and the link component can be formed as separate units, so that assembly work can be facilitated. Even when the flap 2t malfunctions, the unit can be inspected or replaced by removing only the discharge port 2o.

<Opening / closing mechanism of flap 2t>
FIG. 4A is an enlarged conceptual view of a portion I in FIG. 2B showing the opening and closing mechanism of the flap 2t. FIG. 4B is a state in which the flap 2t shown in FIG. FIG. 4C is a diagram showing a state in which the flap 2t shown in FIG. 4A is fully opened.

  As shown in FIG. 4A, a flap opening / closing motor 61 such as a stepping motor is fixed to the structural member 1k of the air purifier 1 and is attached to a drive shaft (not shown) of the flap opening / closing motor 61. The one end 62a of the drive link 62 is fixed.

  The flap 2t is rotatably supported on the flap drive shaft 62b1 fixed to the other end 62b of the drive link 62.

  Further, one end 63a of the follower link 63 is rotatably supported by the structural member 1k of the air cleaner 1, and a flap 2t is freely rotatable on the flap follower shaft 63b1 fixed to the other end 63b of the follower link 63. It is supported.

  With this configuration, as shown in FIG. 4A, when the flap opening / closing motor 61 rotates in the direction of the arrow α31, the drive link 62 rotates in the direction of the arrow α31. As shown in FIG. 4C, the flap 2t is fully opened.

  On the other hand, when the flap 2t is closed from the fully opened state of the flap 2t shown in FIG. 4C, the drive link 62 is rotated in the arrow α32 direction by rotating the flap opening / closing motor 61 in the arrow α32 direction. Along with this, the driven link 63 rotates, and the flap 2t is closed as shown in FIG.

  FIG. 4B shows a case where the flap 2t shown in FIG. 4A is opened 45 degrees from the closed state for reference.

  For example, when the air cleaning mode is selected in the air cleaner 1, the flap 2t is fully opened (for example, an opening angle of 90 degrees) as shown in FIG. When the clothes drying mode is selected, the flap 2t repeatedly performs the reciprocating motion between the opening angle of 45 degrees and the opening angle of 90 degrees as shown in FIG. The air discharged from the outlet 2o is blown in the vertical direction, and air is blown up and down on the clothes to promote drying of the clothes. That is, when the clothes drying mode is selected, the rotational reciprocation between the predetermined angle opened from the horizontal and the full opening is repeated. When the clothes drying mode is selected, the flap 2t may be repeatedly rotated and reciprocated between an opening angle of 10 degrees and an opening angle of 90 degrees.

  For example, when the strong deodorization mode is selected in the air cleaner 1, as shown in FIG. 4C, the flap 2t is fully opened, reducing the ventilation resistance of the discharge port 2o, enabling a large air volume operation, By blowing upward, the indoor air is circulated to guide the air in the opposite direction of the air purifier, thereby promoting the deodorizing process for the entire indoor space. That is, the opening angle of the flap 2t in the strong deodorizing mode is the same as the opening angle of the flap 2t in the air cleaning mode.

  When the humidifying mode or the skin moisturizing mode in which the humidifying function is activated is selected, the flap 2t is in a state of an open angle of 45 degrees as shown in FIG. 4B, and is discharged from the outlet 2o of the air cleaner 1. The air to be blown in the front diagonal direction facilitates the supply of humidified clean air to the center of the room where the user is located.

  When the dehumidifying mode in which the dehumidifying function is activated is selected, the flap 2t is in a state of an open angle of 45 degrees as shown in FIG. 4B, and the front of the air discharged from the discharge port 2o of the air cleaner 1 is used. The supply of the dehumidified clean air that is blown in an oblique direction to the center of the room where the user is located is promoted.

  Further, when the dew condensation saving mode in which the humidifying function and the dehumidifying function are selected is selected, the flap 2t is in a state of an open angle of 45 degrees as shown in FIG. 4B and is discharged from the discharge port 2o of the air cleaner 1. The air is blown in the forward diagonal direction, and the supply of humidified or dehumidified clean air to the center of the room where the user is located is promoted. That is, the opening angle of the flap 2t in the dehumidifying mode and the dew condensation saving mode is the same as the opening angle of the flap 2t in the humidifying mode and the skin moisturizing mode. The opening angle of the flap 2t in the air cleaning mode and the strong deodorizing mode is larger than the opening angle of the flap 2t in the humidifying mode, the skin moisturizing mode, the dehumidifying mode, and the dew condensation saving mode, and thus the wind direction is also close to the vertical upward direction.

  Further, when the continuous switching spot clear wind mode in which each mode is displayed by LEDs is selected instead of direct selection, the flap 2t is in a horizontal state (not shown) parallel to the floor surface, and the discharge port 2o. The air flow resistance is increased and the air volume is restricted, but the air discharged from the outlet 2o of the operating air cleaner 1 is blown forward, and the fan is used with clean air instead of the fan after bathing or when ironing. it can.

  In addition, when the continuous switching indoor circulation mode in which each mode is displayed with LEDs is selected instead of the direct selection, the flap 2t has a horizontal state (not shown) parallel to the floor surface and an opening angle of 90 degrees. Use to repetitively rotate and reciprocate between them, to blow air discharged from the discharge port 2o of the air purifier 1 upward from the front, to circulate indoor air over a wide range, and to reduce temperature unevenness during air conditioning Can be done with clean air.

  Further, the flap 2t opened during the operation of the air purifier 1 returns the flap 2t to the closed state and stops the operation when the operation is stopped. Thereby, it can prevent that a foreign material and dust enter into the inside of the air cleaner 1 from the discharge port 2o.

  Here, since the members constituting the opening / closing mechanism of the flap 2t are driven to rotate relative to each other, the movement is smooth and the operation reliability is high as compared with the case where the members reciprocate. Therefore, the maintenance frequency of the opening / closing mechanism of the flap 2t can be suppressed. The rotation control of the flap opening / closing motor 61 is performed by the following control device E.

<Control device E of the air purifier 1>
FIG. 5 is a block diagram showing the control device E of the air purifier 1.

  The control device E that controls the operation of the air purifier 1 (see FIG. 1) is in the vicinity of the various operation buttons 50 exposed from the operation panel 60 at the front upper part of the front housing case 3, and the front housing case. 3 in the upper front. A display device (not shown) is provided near the control device E. The operation panel 60 is provided on the upper surface (upper surface) of the air cleaner 1.

  As shown in FIG. 5, the control device E is composed of a microcomputer E1 (hereinafter referred to as microcomputer E1), various motors, various circuits such as a drive circuit such as a heater 33, relays, and the like. By executing the control program stored in the “Only Memory”, the air cleaner 1 is controlled in an integrated manner. When the control program is maintained, the control program is updated using the write circuit E9a and the write connector E9b.

  When the user presses a desired operation button 50 disposed on the operation panel 60 of the air purifier 1, an operation signal is input to the control device E, and the air purifier 1 is controlled by the control device E according to the operation signal. Is controlled.

  In addition, the air cleaner 1 has a remote control (not shown) that can be remotely operated. When the user operates the remote control, the remote control wirelessly receives the control device E via the remote control light receiving unit IC (E2). It is the structure which can perform remote control of the air cleaner 1 by giving and receiving a signal.

  Note that the mode in which the heater 33 is not used (air cleaning mode, strong deodorization mode, humidification mode, and skin moisturizing mode) allows operation by the remote controller in the control device E, but in order to limit unintended operation, the heater In the mode using 33 (dehumidification mode, dew condensation save mode, clothes drying mode), the control device E cannot be operated by the remote controller. In addition, the remote control is displayed by printing or sticking to indicate that the mode in which the heater 33 is used cannot be operated by the remote control, thereby preventing misuse and malfunction.

  The mode in which the heater 33 is not used operates in response to pressing of the power on / off button 51, whereas the mode in which the heater 33 is used presses the power on / off button 51 to pause or stop. It is comprised in the control apparatus E so that it may transfer later, and the restriction | limiting of an operation | movement is aimed at.

  Alternatively, in the mode in which the heater 33 is used, in the control device E, the pressing time of the operation button 50 is set longer than in the mode in which the heater 33 is not used, thereby limiting the operation. For example, if the operation button 50 for selecting the mode using the heater 33 has a pressing time of 0.5 seconds, the operation button 50 for selecting the mode using the heater 33 is selected by operating the pressing time for 1 second or longer. Thus, the operation can be limited as the operation button 50 for selecting a mode in which the heater 33 that operates immediately by the pressing operation is not used. In addition, the fact that the pressing time is selected by the operation for 1 second or more in the vicinity of the operation button 50 for selecting the mode for using the heater 33 by printing or sticking and the fact that the operation only by the main body is possible are indicated. Therefore, it is possible to prevent the misrecognition of the restriction of the operation and the misuse or the failure state.

  Thereby, the operation | movement of the heater 33 which is not intended can be prevented beforehand.

  Here, the air purifier 1 is a humidity sensor E3 that detects the humidity of indoor air to be used for control by the control device E3, an odor sensor E4 that detects the odor of indoor air, and dust in the indoor air. A dust sensor E5 for detecting the amount of

  As shown in FIGS. 2B and 3, the suction plate 10 that guides the suction flow to the turbo fan 7 a is formed so as to surround the turbo fan 7 a together with the fan casing 8.

<Water tank 13>
The water tank 13 shown in FIG. 2B and FIG. 3 is a member that contains water for performing a humidification mode in which the air purified by the filter unit 5 is humidified by the air purifier 1.

  Drawing 6 is a perspective view which looked at water tank 13 of an embodiment from the slanting upper part.

  As shown in FIG. 6, the water tank 13 includes a water tank box 13a in which water to be supplied is stored and a water tank lid 13b that covers the water tank box 13a.

  The water tank box 13a of the water tank 13 is molded into a box shape having a bottom plate and front / rear / left / right side plates using a synthetic resin such as polypropylene, for example. A grip portion 13a1 for pulling out the water tank 13 is formed, and a viewing window 13a2 for viewing the water level in the water tank box 13a is formed.

  The water tank lid 13b of the water tank 13 is formed, for example, using a synthetic resin such as polypropylene, with a shape gradually lowering from the outer peripheral area to the center as shown in FIG. A water collecting hole 13b1 is formed to allow water condensed in the condenser 11 and dripped from the condensed water discharge hole 11c1 (see FIG. 17) of the condenser 11 into the water tank box 13a. Further, the water tank lid 13b is provided with a water supply hole 13b2 for allowing the user to absorb water when the water in the water tank box 13a is insufficient or disappears.

  Furthermore, the water tank lid 13b is provided with water supply protrusions 13b3 having suction holes 13b31 for sucking water in the water tank 13 to the vaporization filter unit 15 by the pump p described later, and water overflowing from the vaporization filter unit 15. A return projection 13b4 having a return hole 13b41 for returning the water tank 13 is formed.

  The water tank lid 13b has a suction hole 13b31 of the water supply projection 13b3 of the water tank lid 13b so as to continue to the lower part of the water tank box 13a so that the water in the lower part of the water tank box 13a can be sucked up. It is molded into.

<Vaporization filter unit 15>
FIG. 7A is a perspective view showing the vaporization filter unit 15, and FIG. 7B is a perspective view showing the vaporization filter 6 for imparting moisture to the air in the vaporization filter unit 15.

  As shown in FIG. 7A, the vaporization filter unit 15 includes a vaporization filter 6 for imparting moisture to the air cleaned in the air cleaner 1, and a vaporization filter case 17 that holds the vaporization filter 6. The vaporizing filter 6 and the vaporizing filter case 17 are held, and a water supply tray 18 for containing water soaked into the vaporizing filter 6 is included.

  Further, the vaporization filter unit 15 has a tray water supply projection 19 in which a water supply hole 19a for supplying water pumped up from the water tank 13 by the pump p to the water supply tray 18 and water in the water supply tray 18 are predetermined. A tray reflux protrusion 20 having a drain hole 20a for returning the overflowed water to the water tank 13 when the water level is exceeded is formed.

  The water supply hole 19a of the tray water supply projection 19 continues above the water supply tray 18, and the water pumped up by the pump p from the water tank 13 and flowing through the water supply hole 19a is dropped into the water supply tray 18 from above. Water is supplied.

The configuration is returned to the water tank 13.

  As a result, a water level sensor for detecting the water level in the water supply tray 18 becomes unnecessary, and strict control of the amount of water in the water supply tray 18 becomes unnecessary.

  The vaporization filter 6 shown in FIG. 7B is made of a material having water absorption, and has a large number of pores for absorbing water in the water supply tray 18 by capillary action.

  In the vaporization filter unit 15 shown in FIG. 7A, the lower part of the vaporization filter 6 is immersed in the water in the water supply tray 18 supplied with water from the water tank 13 using the pump p, and is absorbed into the vaporization filter 6 by capillary action. The

  In this manner, the vaporized filter 6 having moisture is filtered by the filter unit 5 (see FIGS. 2 (b) and 3), and the air purified by the filter unit 5 (see FIG. 2 (b)) is cleaned. By passing the air from the left side of 6 to the rear side (right side of the vaporizing filter 6 shown in FIG. 2B), the air is moistened and humidified, and the humidifying mode of the air cleaner 1 is performed.

  Here, the operation of the pump p is driven by the control device E using the humidity detected by the humidity sensor E3 shown in FIG. 5, the air volume of the air cleaner 1 by the fan motor 7 and the time as parameters. It is controlled by being controlled (see FIG. 5).

  For example, at the start of the operation of the air cleaner 1 or when moisturizing is emphasized in a mode such as skin moisturizing when the skin moisturizing button 56 (see FIG. 1) is pressed, the air volume by the fan motor 7 is increased. The pump motor p1 is driven and controlled, the pump p is operated, water is supplied to the water supply tray 18, and humidification is promoted. For example, assuming that the air volume is in four stages of low air volume, low, standard (medium), strong, and turbo, when the emphasis is on humidification, the strong air volume with the largest air volume is set except for turbo.

  Alternatively, if the humidity detected by the humidity sensor E3 is low, humidification is necessary. Therefore, the control device E drives and controls the humidification pump motor p1, operates the pump p, and supplies water to the water supply tray 18.

  Alternatively, if the user depresses the air volume switching button 52a (see FIG. 1) and selects a high air volume, the room is dried as it is, so that the control device E drives and controls the humidifying pump motor p1 to operate the pump p. Water is supplied to the water supply tray 18 and humidification is performed using the vaporization filter 6.

  Alternatively, when the air cleaner 1 is operated for the first time, if it takes about 5 seconds for water to penetrate the entire vaporization filter 6, “the pump p is operated for 10 seconds and water is supplied to the water supply tray 18. The pump p is stopped for 5 seconds, and the water supplied to the water supply tray 18 is infiltrated into the vaporization filter 6. Subsequently, the pump p is operated for 5 seconds and water is supplied to the water supply tray 18. Thereafter, the pump p is changed to 5 If the control device E controls the driving pattern of the pump p like the above, the vaporizing filter 6 is soaked with the water supplied to the water supply tray 18... The operation time is shortened.

  Therefore, the life of the air cleaner 1 can be extended. In addition, there is an effect of reducing power consumption.

  Further, since the pump p is operated only when humidification is performed and water is supplied to the water supply tray 18, the vaporization filter 6 is in a dry state in other operation modes. As a result, it is possible to suppress the reduction of the humidifying ability by reducing the adhesion of the calc component contained in the tap water to the vaporizing filter 6, and the life of the vaporizing filter 6 can be extended.

  The water supply hole 21b of the pump joint unit 21 for supplying water to the water supply tray 18 (see FIGS. 3 and 7A) is located above the tray water return hole 21c of the pump joint unit 21 (see FIG. 9). By arranging, water is supplied to the water supply tray 18 from above, and water that overflows and drains from the water supply tray 18 is drained from below, so that the water in the water supply tray 18 circulates and is deadly water. That is, water staying in the water supply tray 18 is not generated, and a clean state can be maintained.

<Removal and attachment of water tank 13 and vaporization filter unit 15 from air cleaner 1>
FIG. 10A is a perspective view showing a case where the water tank 13 and the vaporization filter unit 15 are housed in the air cleaner 1, and FIG. 10B shows the water tank 13 removed from the air cleaner 1 and It is a perspective view which shows the relationship with the pump joint unit 21 in the air cleaner 1 in the case of attaching the vaporization filter unit 15 to the air cleaner 1, respectively.

  As shown in FIG. 10 (a), when water is supplied to the water tank 13, the water tank 13 in the air purifier 1 is pulled out by the user with the handle 13a1 of the water tank 13, so that the white arrow β11 Thus, the water tank 13 can be taken out of the air purifier 1.

  Here, the air purifier 1 is provided with a water tank sensor E6 (see FIG. 5) for detecting that the water tank 13 has been taken out of the air purifier 1, and the water tank 13 is disposed outside the air purifier 1. When it is taken out, the control device E turns off the power of the air cleaner 1 to limit the operation of the air cleaner 1.

  When the vaporizing filter unit 15 is cleaned, as shown in FIG. 10A, the filter take-out lid 1t of the air purifier 1 is opened, and the vaporizing filter unit 15 in the air purifier 1 is indicated by a white arrow β12. Can be taken out of the air purifier 1 (see FIG. 10B).

  Here, like the water tank 13, the air cleaner 1 is provided with a sensor (not shown) that detects that the vaporizing filter unit 15 has been taken out of the air cleaner 1. Using this sensor, when the vaporizing filter unit 15 is taken out of the air purifier 1, the power of the air purifier 1 may be turned off to limit the operation of the air purifier 1.

  On the other hand, when the removed water tank 13 is attached to the air cleaner 1, as shown in FIG. 10B, the water tank 13 is inserted into the tank attachment port 1m of the air cleaner 1 as indicated by the white arrow β21. The water supply projection 13b3 and the recirculation projection 13b4 of the water tank 13 are fitted into the suction hole 21a and the tank return hole 21d of the pump joint unit 21 in the air purifier 1, respectively. Attach to 1.

  The water supply protrusion 13b3 and the recirculation protrusion 13b4 of the water tank 13 are respectively a conical surface 21a1 (see FIG. 9) of the suction hole portion 21a of the pump joint unit 21 in the air cleaner 1 and a conical surface 21d1 of the tank return hole portion 21d. (Refer to FIG. 9) and can be smoothly inserted into the suction hole 21a and the tank return hole 21d of the pump joint unit 21.

  On the other hand, when attaching the removed vaporization filter unit 15 to the air purifier 1, as shown in FIG. 10B, the vaporization filter unit 15 is connected to the filter port 1n of the air purifier 1 as indicated by the white arrow β22.

It can be guided and smoothly fitted into the water supply hole 21b1 and the tray water return hole 21c of the pump joint unit 21.

  With this configuration, when water is supplied to the water tank 13, only the water tank 13 can be taken out independently from the vaporization filter unit 15 having the vaporization filter 6, so that the water supply to the water tank 13 is easy and the handleability is excellent.

  Further, as shown in FIG. 10A, since the water tank 13 and the vaporization filter unit 15 in the air cleaner 1 are independent from each other, the water tank 13 and the vaporization filter unit 15 in the air purifier 1 are disposed. A space is formed in the space, and a strength member can be provided in the space, and a support structure for the air cleaner 1 having high strength can be obtained.

<< Structure of dehumidifying unit >>
In the air cleaner 1, a dehumidifying unit for performing a dehumidifying mode for humidifying air that has been filtered through the filter unit 5 and cleaned as indicated by the white arrow α11 in FIG. 2B will be described.

  FIG. 11 is a cross-sectional view taken along the line DD in FIG. 2B showing the dehumidifying unit such as the desiccant rotor 9 and the heater 33 as viewed from the rear (the right side in FIG. 2B). FIG. 12 is a perspective view showing a state where the desiccant rotor 9, the heater case 34 covering the heater 33, the fan casing 31, and the like are removed.

  13 is a cross-sectional view taken along the line EE of FIG. 2B showing the vicinity of the condenser 11 constituting the dehumidifying unit, and FIG. 14 is a cross-sectional view taken along the line FF showing the vicinity of the condenser 11 constituting the dehumidifying unit. FIG.

  The dehumidifying unit is rotated as indicated by the arrow β11 in FIG. 11 and passes through the filter unit 5 (see the white arrow α11 in FIG. 2B) to absorb the moisture of the cleaned air, and the desiccant rotor 9 9 is a blower source for sending warm air to the fan 9, and a dehumidifying fan (not shown) covered by a fan casing 31 (see FIGS. 11 and 12) and heat supplied to the air covered by the heater case 34 and sent from the dehumidifying fan. A heater 33 for generating warm air, a condenser 11 (see FIG. 13) for cooling the air containing water vaporized from the desiccant rotor 9 by the hot air heated by the heater 33, and condensing the water in the air, and a desiccant A light reflection sensor 40 (see FIGS. 5, 14, and 16 (b)) that detects the rotation of the rotor 9 is provided.

  Here, in the condenser 11 shown in FIG. 13, the air containing the water vaporized from the desiccant rotor 9 by the hot air heated by the heater 33 is passed from the top to the bottom in the lattice portion 11b1 described later. And the water in the air is condensed.

  As shown in FIG. 2B, the air cleaner 1 has a desiccant rotor 9 that absorbs moisture of air in the dehumidifying unit disposed above and a vaporization filter unit 15 disposed below the desiccant rotor 9. The air cleaner 1 is a condenser 11 having a lattice part 11b1 of a condensing part having a flow path for condensing the air vaporized by the moisture absorbed by the desiccant rotor 9, and in front of the desiccant rotor 9 and the vaporizing filter unit 15. Covered and placed.

  Thereby, the desiccant rotor 9 and the vaporization filter unit 15 are arranged up and down, and the condenser 11 is arranged so as to cover the front of the desiccant rotor 9 and the vaporization filter unit 15, so that the air purifier 1 can be thinned. is there.

  Moreover, since the dimension of the up-down direction of the condenser 11 which has a condensation part can be enlarged, the condensation performance of the condenser 11 can be improved.

  Furthermore, since the condenser 11 covers the front of the desiccant rotor 9 and the vaporization filter unit 15, the ventilation resistance until the sucked air is discharged can be made the same, so that the same air volume is set regardless of the operation mode. In addition, since it is not necessary to change the rotational speed of the centrifugal fan 7a depending on the operation mode, the generated operation sound does not change. More preferably, it is preferable to adjust the sizes of the cells (holes) of the desiccant rotor 9 and the vaporization filter 6 so that the air flow is the same by adjusting the ventilation resistance.

<Configuration of fan casing 31, heater 33, heater case 34, etc.>
In the fan casing 31 shown in FIG. 11 and FIG. 12, a dehumidifying fan (see FIG. 5) driven by a dehumidifying fan motor E7 (see FIG. 5) to supply the air for vaporizing the moisture absorbed by the desiccant rotor 9 therein. (Not shown) is disposed, and a heater assembly 33S is disposed adjacent to the fan casing 31.

  Here, an assembly including the heater 33 and the heater case 34 in which the heater 33 is provided is referred to as a heater assembly 33S.

  FIG. 15A is a perspective view showing a heater assembly 33S having a heater 33 and a heater case 34 in which the heater 33 is provided. FIG. 15B is a perspective view of the heater assembly 33S viewed from the heater 33 side. It is a figure.

  Here, in the connecting portion 30S between the fan casing 31 and the heater assembly 33S (see FIG. 15) shown in FIG. 12, a blower opening (not shown) is opened in the fan casing 31, and the fan casing 31 blows air. An air receiving opening (not shown) is opened in the heater case 34 so as to face the opening (not shown), and the air blown by the dehumidifying fan (not shown) in the fan casing 31 has the heater 33. The structure is sent to the assembly 33S.

<Fan casing 31>
The fan casing 31 shown in FIGS. 11 and 12 covers the dehumidifying fan (not shown) by, for example, injection molding using polystyrene, and is condensed by the air after the moisture is condensed by the condenser 11. The heater assembly is provided with a dehumidifying fan that has an air receiving port (not shown) and a blower port (not shown) connected to the heater case 34 after the moisture has been condensed by the condenser 11. It is formed in a shape having an air passage to be sent to 33S.

<Heater assembly 33S>
The heater case 34 of the heater assembly 33S shown in FIGS. 11 and 12 includes a first heater case 34a to which the nichrome wire heater 33 is attached and a flat plate-like second heater case 34b as shown in FIG. Manufactured and assembled together.

  The heater 33 has a first heater and a second heater, and obtains a predetermined heat generation amount. In addition, the heater 33 may be composed of a single or a plurality, and the number is not limited.

  The first heater case 34a shown in FIG. 15 is formed by drawing using, for example, an aluminum-plated steel plate, and the air receiving portion 34a1 in which an air receiving port (not shown) is opened and the heater 33 are attached and the heater 33 is attached. Is formed into a shape having a heater accommodating portion 34a2 from which a connection k for flowing a current flows.

  The second heater case 34b shown in FIG. 15B is formed in a substantially flat plate shape using, for example, a stainless steel plate, and an air blowing hole 34b1 for sending air heated by the heater 33 is opened.

  As shown in FIGS. 11 and 12, the heater assembly 33 </ b> S is opposed to a blower opening (not shown) of the fan casing 31 and adjacent to the fan casing 31, and has a blower hole 34 b 1 of 34 b of the second heater case 3. , And attached to the desiccant rotor 9 that absorbs moisture of the air purified through the filter unit 5.

  Thereby, the air after moisture is condensed in the condenser 11 is sent to the fan casing 31 via the blower port 11a2 (see FIGS. 16B and 17) of the condenser 11 and the condensed air receiving port. The sent air in the fan casing 31 is blown into the heater case 34 of the heater assembly 33S by a dehumidifying fan (not shown) through the blower opening of the fan casing 31 and the air receiving opening of the heater case 34. . Then, the air heated by the heater 33 is blown from the air blowing hole 34b1 of the second heater case 34 shown in FIG. 15B to the desiccant rotor 9 that has absorbed moisture of the cleaned air, and is applied to the desiccant rotor 9. Vaporizes absorbed moisture.

  According to this configuration, in the heater case 34 having the heater 33 facing the desiccant rotor 9, as shown in FIGS. 12 and 15, the first heater case is close to the heater 33 and faces the moisture absorption surface of the desiccant rotor 9. Since the wind receiving portion 34a1 (see FIG. 12) of 34a is made of metal, the resin fan casing 31 and the heater 33 are separated from each other, and the resin fan casing 31 is melted by the heat of the heater 33. It is suppressed.

  Further, the fan casing 31 and the heater 33 are connected via a wind receiving portion 34a1 so as not to directly face each other. That is, the fan casing 31 and the heater case 34 are connected with a predetermined angle so that the air blowing hole 34b1 does not face the air blowing hole 34b1.

  Thereby, the radiant heat of the heater 33 does not hit the fan casing 31, and the risk of deformation or melting can be reduced even when the heater 33 is abnormal.

  Further, since the wind receiving portion 34a1 of the first heater case 34a is made of metal, the heat conductivity is high, and the temperature of the air sent from the fan casing 31 and flowing through the wind receiving portion 34a1 of the first heater case 34a is the heater 33. As a result, the saturation absolute humidity is increased, and the dew condensation in the wind receiving portion 34a1 of the first heater case 34a is suppressed.

<< Rotation detection of desiccant rotor 9 >>

A central portion 36a in which the hole 36a1 is formed, four radial portions 36b formed radially from the central portion 36a, and a gear accommodating portion 36c1 that connects the radial portions 36b and accommodates the rotor drive gear 37 are formed. And an outer peripheral portion 36c.

  Here, when the rotor drive gear 37 is driven by the desiccant drive motor 37m shown in FIG. 5, the outer peripheral gear 9b rotates, and the desiccant rotor 9 is driven to rotate. The desiccant drive motor 37m has a rotation sensor 37m1, and the rotation detection signal of the desiccant drive motor 37m detected by the rotation sensor 37m1 is input to the microcomputer E1, and the rotation of the desiccant drive motor 37m is controlled.

  The desiccant rotor support member 36 shown in FIG. 16B is formed with the radiating portion 36b, so that the radiating portion 36b is formed as shown in FIG. 14 in the cross-sectional view taken along the line F-F in FIGS. The air purified through the filter unit 5 hits the desiccant rotor 9 through the space between them.

  A part of the radiating portion 36b of the desiccant rotor support member 36 shown in FIG. 16B is formed in the rib-like radiating portion 36b1, and the light reflection type sensor 40 is formed in the dead space of the rib 36b11 of the rib-like radiating portion 36b1. Is arranged.

  The light reflection type sensor 40 detects the reflected light by applying light to the radiation support portion 9c2 (see FIG. 16C) of the metal desiccant holding member 9c as the desiccant rotor 9 rotates. The rotation of the desiccant rotor 9 can be detected.

  By attaching the light reflection type sensor 40 to the rib-like radiation portion 36b1 of the desiccant rotor support member 36, an attachment part for attaching the light reflection type sensor 40 is unnecessary, and a simple configuration is obtained. Therefore, cost reduction is possible.

  In addition, as shown in FIG. 16B, the light reflection sensor 40 is disposed in the dead space of the rib-shaped radiation portion 36b1 of the desiccant rotor support member 36, and thus contributes to the downsizing of the air cleaner 1. .

  The condensing lower member 11c is formed with locking claws 11c2 of locking portions for locking in the locking holes 11b41 of the locked portions 11b4 of the condensing member 11b at the upper portions of the front surface and the back surface.

  Condensation holding members 11d and 11e shown in FIG. 17 and FIG. 18 are long parts each having a U-shaped cross section manufactured using a thin steel plate, respectively, a condensing upper member 11a, a plurality of condensing members 11b, The condensing lower member 11c is configured to be squeezed and fixed inside with an elastic force.

  The assembly of the condenser 11 is as follows.

  As shown in FIG. 18, first, the condensing member 11b is elastically deformed and engaged with the engaging holes 11b41 of the engaged portions 11b4 of the other condensing members 11b on which the upper engaging claws 11b3 are arranged on the upper side. While being stopped, the locking hole 11b41 of the lower locked portion 11b4 is elastically deformed and locked to the locking claws 11b3 of the other condensing member 11b disposed on the lower side. The condensing member 11b is connected.

  Then, the locking claw 11b3 of the uppermost condensing member 11b is elastically deformed and locked in the locked hole 11a51 of the locked portion 11a5 of the condensed upper member 11a, and the condensed upper member 11a is being condensed in the uppermost portion. It connects with the member 11b.

  Subsequently, the locking claw 11c2 of the condensed lower member 11c is elastically deformed and locked in the locked hole 11b41 of the locked portion 11b4 of the lower condensing member 11b, and the condensed lower member 11c is condensed in the lowermost condensation. It connects with the middle member 11b.

  Finally, as shown in FIG. 17, the condensing holding members 11d and 11e having a U-shaped cross section from the left and right sides of the connecting body of the condensing upper member 11a, the four condensing members 11b, and the condensing lower member 11c are shown.

  Therefore, the ability to condense the moisture-containing air is stabilized and the condensation performance is good.

  Further, since the condenser 11 is configured by connecting a plurality of the condensing members 11b, the lattice portion 11b1 can be shortened, and the flow separated into the respective lattice portions 11b1 joins at the joint portion of the condensing member 11b. Therefore, the flow between the lattice portions 11b1 can be made uniform by the merging portion, and the heat exchange efficiency can be improved.

  Of course, the position of the locking part and the position of the locked part in the condenser 11 may be provided at opposite positions.

<< Operation of Air Cleaner 1 >>
As described above, the operation control by pressing the operation button 10 of the operation panel 60 in the air cleaner 1 shown in FIG. 1 is performed by the control device E (see FIG. 5).

  When the power on / off button 51 of the operation panel 60 on the upper front surface of the air cleaner 1 is pressed, the power of the air cleaner 1 is turned on.

  By pressing the child lock button 52 of the operation panel 60 shown in FIG. 1, even if the child presses the operation buttons 53 to 59, the operation cannot be performed.

  When the air volume switching button 52a of the operation panel 60 shown in FIG. 1 is pressed, the air volume of the air cleaner 1 can be increased by increasing the rotation speed of the fan motor 7, or the air volume can be decreased by decreasing the rotation speed of the fan motor 7.

  When the standard button 53 (standard emptying button) on the operation panel 60 is pressed, the air cleaning mode is selected, the fan motor 7 is operated, and the air is passed through the clearance c (see FIGS. 1 and 2B) as shown in FIG. As shown by the hollow arrow α11 in (b), the air that has been suctioned and purified through the filter unit 5 is guided by the fan casing 8, and the discharge port 2o in which the flap 2t is opened (FIG. 1, FIG. 1). 2 (b)).

  When the strong deodorizing button 54 of the operation panel 60 shown in FIG. 1 is pressed, the strong deodorizing mode of the air cleaning mode is selected, and the sensitivity of the odor detected by the odor sensor E4 is set to the air cleaning mode (according to the pressing of the standard button 53). Operation mode), the sensitivity of dust detected by the dust sensor E5 is less sensitive than the air cleaning mode, and the air cleaning mode can be operated sensitively to the odor of air.

  When the humidifying button 55 on the operation panel 60 shown in FIG. 1 is pressed, a humidifying function is added to the air cleaning mode (humidifying mode), the pump p of the pump joint unit 21 is in an operating state, and the water supply tray 18 of the vaporizing filter unit 15 is activated. (Refer to FIG. 7 (a)), the vaporization filter 6 contains the water in the water supply tray 18, the air purified through the filter unit 5 is allowed to flow through the vaporization filter 6 and humidified, and the flap 2t is It can discharge | emit from the open discharge port 2o (refer FIG. 1, FIG.2 (b)).

  When the skin moisturizing button 56 of the operation panel 60 shown in FIG. 1 is pressed, humidification can be performed sensitively to the humidity of the air detected by the humidity sensor E3 when the humidification function is added to the air cleaning mode. For example, when the humidification button 55 is pressed, the humidification function works normally in the air purification mode when the humidity is 50% or less. However, when the humidity retention button 56 is pressed when the humidity is 60% or less, the humidification function works in the air purification mode. That is, in the skin moisturizing mode, the set humidity is increased by about 20% with respect to the humidifying mode. Therefore, in the skin moisturizing mode, the room can be kept at a higher humidity (for example, 60%) than in the humidifying mode.

  When the dehumidifying button 57 on the operation panel 60 shown in FIG. 1 is pressed, a dehumidifying mode in which a dehumidifying function is added to the air cleaning mode is selected.

  In the dehumidifying mode, the desiccant rotor 9 of the dehumidifying unit operates as indicated by an arrow β11 in FIG. 11, and a dehumidifying fan (not shown) in the fan casing 31 (see FIGS. 11 and 12) is operated. (See FIGS. 11 and 12)) The heater 33 covered with electricity is energized, and the desiccant rotor 9 absorbs the air purified through the filter unit 5 as indicated by the white arrow α11 in FIG. It can dehumidify and can discharge | emit from the discharge port 2o (refer FIG. 1, FIG.2 (b)) by which the flap 2t was open | released.

  When the dew condensation save button 58 of the operation panel 60 shown in FIG. 1 is pressed, a predetermined humidity, for example, the humidity of air detected by the humidity sensor E3 is increased to 50% from the state in which the humidifying function in the air cleaning mode is added. In this case, the operation can be switched to a dehumidifying mode in which a dehumidifying function is added to the air cleaning mode or the air cleaning mode, and indoor dew can be suppressed.

  When the clothes drying button 59 on the operation panel 60 shown in FIG. 1 is pressed, in the dehumidifying mode, the rotational speed of the fan motor 7 shown in FIG. 2 (b) is increased, and the outlet 2o (FIG. 1, FIG. 1) with the flap 2t opened. The air volume from Fig. 2 (b) is increased, and the flap 2t is reciprocated from a small angle to a large angle, and the wind is sent to the entire dried clothes according to the behavior of the flap 2t, that is, while changing the wind direction. The clothes can be dried. For example, the air volume is the strong air volume with the highest air volume except for the turbo.

  Furthermore, since the odor sensor E4 and the dust sensor E5 are provided, the odor and dust in the room can be reduced by changing the air volume and the direction of the wind by detecting the change in the odor or the change in the dust concentration during the drying of the clothes and after the operation. Can be removed.

  When stopping the operation of the air purifier 1, the power on / off button 51 is pressed to turn off the power of the air purifier 1.

  As described above, the mode in which the heater 33 is used has a configuration in which the power on / off button 51 is pressed once to turn off the power and the transition is made only after the pause or stop, or the heater 33 is used. In the mode to perform, the pressing time of the operation button 50 is set to be longer by using the time acquired from the oscillator E8 (see FIG. 5) than the mode in which the other heater 33 is not used, and the mode is easily shifted to the mode in which the heater 33 is used. It is restricted so as not to increase reliability.

  As shown in FIG. 1, operation buttons 50 are arranged on the operation panel 60 of the air purifier 1 according to groups of rough mode types such as a dehumidification mode group and a humidification mode group, and are arranged in different colors. An operation button 50 is arranged so that the mode can be selected directly. For example, the standard button 53, the strong deodorizing button 54, the humidifying button 55, and the skin moisturizing button 56 are arranged close to each other as a group of the humidifying mode, the button itself is colored green, the dehumidifying button 57, the dew condensation saving button 58, and the clothes drying The buttons 59 are arranged close to each other as a group in the dehumidifying mode, and the buttons themselves are colored orange.

  Therefore, there is an effect that the user can easily select each mode of the air purifier 1. In addition, since each mode can be selected directly, the air volume appropriate to each mode and the wind direction by the flap are set in advance, so that in many cases, the user only has to select each mode. In addition, since each mode can be selected directly, the number of operations of each mode button and air volume button is reduced compared to the method of switching the mode by continuously pressing the mode selection button. This has the effect of extending the service life. In addition, each mode can be selected directly, and the color of the operation button 50 of the group for selecting the mode using the heater 33, that is, the mode for using the heater 33, is different from the color of the mode not using the heater 33. This has the effect of preventing unintended operations such as unintended heater operation. Further, since each mode can be selected directly, the mode intended by the user is different from the operation mode of the air purifier, and there is an effect that it is possible to prevent an erroneous operation such as unintended heater operation.

<< Effect >>
According to the said structure, while being easy to handle, the air cleaner 1 with high strength and low cost and high reliability can be obtained.
