  Embodiments of the present invention will be described below with reference to the drawings.

<< Overall 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 up from the water tank 13, a desiccant rotor 9 for dehumidifying 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 surrounding the centrifugal fan of the fan motor 7 and the gap between the outer periphery of the centrifugal fan is formed and cleaned toward the upper discharge port 2o. And a spiral fan casing 8 (see FIG. 3) for discharging 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.

  For example, when the air cleaning mode is selected in the air cleaner 1, the flap 2t is gradually opened to be in a fully open state (for example, an opening angle of 90 degrees). In addition, when the clothes drying mode is selected, the flap 2t repeats the rotational reciprocation between the opening angle of 45 degrees and the opening angle of 90 degrees, and the air discharged from the discharge port 2o of the air cleaner 1 The air is blown up and down, and air is blown up and down 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, the flap 2t is fully opened, the ventilation resistance of the discharge port 2o is reduced, a large air volume operation is possible, and the indoor air is blown upward. Is promoted to deodorize the entire indoor space by guiding the air across the air cleaner. 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 an open angle of 45 degrees, and the air discharged from the discharge port 2o of the air purifier 1 is inclined forward. The supply of the clean air that has been blown and humidified to the center of the room where the user is located is promoted.

  When the dehumidifying mode in which the dehumidifying function is selected is selected, the flap 2t is in an open angle state of 45 degrees, and blows air in a diagonal direction in front of the air discharged from the discharge port 2o of the air purifier 1 for dehumidification. The supply of the purified air to the center of the room where the user is located is promoted.

  In addition, when the dew condensation saving mode in which the humidification function and the dehumidification function are selected is selected, the flap 2t is in an open angle state of 45 degrees, and the air discharged from the discharge port 2o of the air purifier 1 is inclined in the front oblique direction. The supply of the clean air that has been blown and humidified or dehumidified 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.

  When the self-drying mode is selected, the flap 2t is fully opened.

  Further, when the start is selected, the flap 2t is in a state of an open angle of 45 degrees.

  When switching the operation mode, the flap 2t is once closed and then opened according to a predetermined operation mode.

  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.

<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.

  The air cleaner 1 has a remote control (not shown) that can be operated remotely, and the user operates the remote control to wirelessly transmit and receive signals to and from the control device E via the remote control light receiving unit IC. The air cleaner 1 may be configured to be remotely operable.

  At that time, the mode in which the heater 33 is not used (air cleaning mode, strong deodorization mode, humidification mode, skin moisturizing mode) allows operation by the remote controller in the control device E, but restricts unintended operation. In the mode using the heater 33 (dehumidification mode, condensation save mode, clothing drying mode), the control device E cannot be operated by the remote controller. In addition, by displaying on the remote controller that the operation using the heater 33 is impossible in the mode in which the heater 33 is used by printing or sticker, it is possible to prevent misuse or malfunction.

  The mode in which the heater 33 is not used operates in response to pressing of the power on / off button 51, while 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

<Filter unit 5>
The filter unit 5 shown in FIG. 2B and FIG. 3 is disposed on the foremost side where the air sucked from the clearance c on the front housing case 3 side hits.

  The filter unit 5 is a pre-filter 5a (see FIG. 3) that removes cotton dust, large dust, and the like from the air sucked from the clearance c on the foremost side of the air cleaner 1 (left side of FIG. 2B). In the center of the filter unit 5, a dust collection filter 5b (see FIG. 3) for removing dust, dust, pollen and other fine particles from the inhaled air is disposed. A deodorizing filter 5c (see FIG. 3) that removes the source of odor from the inhaled air such as activated carbon is disposed on the back side of FIG. 5 (on the right side in FIG. 2B).

<Fan motor 7>
The fan motor 7 shown in FIGS. 2 (b) and 3 is for sucking and discharging air from the air cleaner 1, and is arranged in a fan casing 8 provided inside the main housing case 2. Yes.

  The fan motor 7 is a centrifugal fan for sucking air into the air cleaner 1 from the upper, lower, left, and right clearances c (see FIGS. 1 and 2B) before the air cleaner 1 and rotates the centrifugal fan. And an electric motor for driving.

  The suction plate 10 that guides the suction flow to the turbo fan is formed so as to surround the turbo fan 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.

  Further, the water tank lid has a water supply projection having a suction hole for sucking water in the water tank 13 to the vaporization filter unit 15 by the pump p described later, and water overflowed from the vaporization filter unit 15 in the water tank 13. And a circulation projection having a return hole for returning the inside.

  The suction hole of the water supply projection of the water tank lid 13b is formed in the water tank lid 13b so as to continue to the lower part in the water tank box 13a so that the water in the lower part in the water tank box 13a can be sucked up. Has been.

<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 water supply tray 18 shown in FIG. 7A is a member for storing water to be absorbed by the vaporization filter 6 and extends upward from the outer peripheral portions of the bottom plate 18a and the bottom plate 18a using synthetic resin. A concave shape is formed in which the upper side where the side plate 18b is formed is opened, and a rib (not shown) for supporting the vaporizing filter case 17 holding the vaporizing filter 6 is formed therein.

  In addition, the water supply tray 18 is formed with an overflow hole (not shown) for allowing the water supplied from the water tank 13 to overflow when the water supplied from the water tank 13 exceeds a predetermined water level. The overflow hole of the water supply tray 18 is connected to the drain hole 20 a of the tray return protrusion 20 of the vaporization filter unit 15, and the water overflowed from the overflow hole of the water supply tray 18 passes through the drain hole 20 a of the tray return protrusion 20. 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 Then, the vaporization filter 6 is soaked with the water supplied to the water supply tray 18. If the control pattern of the driving pattern of the pump p is controlled by the control device E, the time for which the pump p does not operate wastefully and stops As a result, 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.

<Pump joint unit 21>
FIG. 8 is a schematic perspective view showing the location where the water tank 13 below the section BB in the air purifier 1 shown in FIG. 2A is disposed and the pump joint unit 21, and FIG.

  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. Then, the water supply protrusion and the recirculation protrusion of the water tank 13 are fitted into the suction hole 21 a and the tank return hole 21 d of the pump joint unit 21 in the air cleaner 1, respectively. Install.

  The water supply protrusion and the recirculation protrusion 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 (see FIG. 9) of the tank return hole portion 21d. 9) 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.

《Dehumidification unit structure》
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. It is not necessary to change the rotational speed of the centrifugal fan depending on the operation mode, so that 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.

  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 air volume range during the automatic operation in the skin humidification mode is “quiet”, “weak”, “medium”, and “strong”. If it is desired to change the air volume according to preference, the air volume can be switched by the air volume switching button 52a.

  When the dehumidifying and purifying button 54 on the operation panel 60 shown in FIG. 1 is pressed for 1 second or longer, the dehumidifying mode, the clothing drying mode, or the dew condensation saving mode is selected. When the dehumidifying and purifying button 54 is pressed for 1 second or longer in the dehumidifying mode, the mode is switched to the clothing drying mode. When the dehumidifying and purifying button 54 is pressed for 1 second or longer in the clothes drying mode, the mode switches to the dew condensation saving mode. When the dehumidifying and purifying button 54 is pressed for 1 second or longer in the dew condensation saving mode, the mode is switched to the dehumidifying mode. In the dehumidifying mode, if you want to switch to the dew condensation saving mode, press the dehumidifying and purifying button 54 for 1 second or longer to enter the clothing drying mode, then release the dehumidifying and purifying button 54 and press the dehumidifying and purifying button 54 again for 1 second or longer. There is. The same operation needs to be performed when the dehumidifying mode is desired in the clothing drying mode or when the clothing drying mode is desired in the condensation save mode.

  When the dehumidifying mode is selected, the dehumidifying display above the dehumidifying and purifying button 54 is turned on, and the fan motor 7 and the flap 2t are operated. In the dehumidifying mode, the air is dehumidified and dry clean air is sent to the room. The desiccant type is used because the dehumidifying power is stable even at low temperatures. While the desiccant rotor 9 of the dehumidifying unit operates as indicated by an arrow β11 in FIG. 11, a dehumidifying fan (not shown) in the fan casing 31 (see FIGS. 11 and 12) operates, and a heater case 34 (FIG. 11, FIG. 11). The heater 33 that is covered by FIG. 12) is energized, and as shown by the white arrow α11 in FIG. 2B, the air that has passed through the filter unit 5 is absorbed by the desiccant rotor 9 and dehumidified.

The air volume range during the automatic operation in the dehumidifying mode is “static”, “weak”, “medium”, and “strong”. If it is desired to change the air volume according to preference, the air volume can be switched by the air volume switching button 52a.

  When the dew condensation save mode is selected, the dew condensation save display above the dehumidifying and purifying button 54 is turned on, and the fan motor 7 and the flap 2t are operated. In the condensation save mode, the humidification operation is performed during heating, and then the heating is turned off at bedtime, etc., and when the humidity rises, the operation is automatically switched to the dehumidification operation to suppress condensation in the room. When a predetermined humidity, for example, the humidity of the air detected by the humidity sensor E3 is increased to 60% from the state where the humidifying function of the air cleaning mode is added, the dehumidifying function is added to the air cleaning mode or the air cleaning mode. The operation can be switched to the dehumidifying mode, and the indoor dew can be suppressed. For example, when the condensation save mode is selected and the heater is turned on, the humidification operation is performed because the humidity is low. Thereafter, when the humidity reaches 50%, a humidifying operation is performed to keep the humidity. When heating is turned off from this state, the relative humidity increases as the room temperature decreases. When the humidity reaches 60%, the operation is automatically switched to the dehumidifying operation to prevent condensation in the room (FIG. 22). By pressing the power on / off button 51 in the dew condensation save mode, the operation is stopped and the power is turned off. In that case, all the lamps are turned off and the flap 2t is closed. The air volume is automatic when the condensation save mode is selected. In the case of automatic air volume, the vehicle operates in “medium” for the first 3 minutes, and thereafter the air volume is switched depending on the degree of air contamination. The air volume range during the automatic operation in the dehumidifying mode is “static”, “weak”, “medium”, and “strong”. If it is desired to change the air volume according to preference, the air volume can be switched by the air volume switching button 52a.

  When the clothes drying mode is selected, the clothes drying display above the dehumidifying and purifying button 54 is turned on, and the fan motor 7 and the flap 2t are operated. In the clothes drying mode, the air volume from the flap increases. In the dehumidifying mode, the rotational speed of the fan motor 7 shown in FIG. 2B is increased, the air volume from the outlet 2o (see FIGS. 1 and 2B) where the flap 2t is opened is increased, and the flap 2t can be reciprocally rotated from a small angle to a large angle, and the wind can be sent to the dried clothes by the behavior of the flap 2t, that is, while changing the wind direction, to dry the clothes. For example, the air volume is the strong air volume with the highest air volume except for the turbo. By pressing the power on / off button 51 in the clothes drying mode, the operation is stopped and the power is turned off. In that case, all the lamps are turned off and the flap 2t is closed. When the clothing drying mode is selected, the air flow becomes turbo and the turbo display blinks. In the case of automatic air volume, the turbo is continuously operated. The airflow range during automatic operation in the dehumidifying mode is “turbo” only. If it is desired to change the air volume according to preference, the air volume can be switched by the air volume switching button 52a.

  The dehumidification mode, clothing drying mode, and condensation save mode are automatically stopped and the power is turned off even after 8 hours have elapsed since the start of operation. Also in this case, all the lamps are turned off and the flap 2t is closed.

  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 direction by detecting the change in the odor or the change in the dust concentration during clothes drying and after driving. Can be removed.

  When the start button 53 is left pressed for more than 1 second on the operation panel 60, the air condition in the room is humidified and cleaned by the degree of air contamination detected by the odor sensor E4, dust sensor E5, temperature sensor, and humidity sensor E3. Or automatically select whether to perform dehumidification or air cleaning and let it start. When humidification / air cleaning is selected and the humidity in the room is low, the `` Let's start '' and `` humidification '' indications light up and the humidification operation is performed, when humidification / air cleaning is selected and the room air is moderate, The “Let me start” and “Keisei” indicators light, and the air cleaning operation is performed. When dehumidification / air purification is selected and the room is high in humidity, the `` Start and start '' and `` dehumidification '' indications light up and dehumidification operation is performed, and when dehumidification / air purification is selected and the room air is moderate, The “Let me start” and “Keisei” indicators light, and the air cleaning operation is performed. When the power on / off button 51 is pressed in the start mode, the operation is stopped and the power is turned off. Alternatively, the system automatically stops and power is turned off when 8 hours have elapsed after starting operation in the start mode. In that case, all the lamps are turned off and the flap 2t is closed. The start mode is selected and the air flow is “strong” during the sensor detection. After detection, it is operated with the air volume according to each mode.

  When the eco operation button 52b of the operation panel 60 is pressed during any one of the start mode, the air purification mode, the strong deodorization mode, the humidification mode, the skin moisturizing mode, the dehumidification mode, and the dew condensation save mode, the eco operation button 52b is pressed. The upper display lights up and eco operation is started. In the eco operation, when the air is clean, the fan motor 7 is repeatedly stopped and operated with a small air volume. In eco operation, if the air remains clean for a long time, it automatically stops and the power is turned off. In that case, all the lamps are turned off and the flap 2t is closed. When the eco operation button 52b is pressed again in the eco operation state, the eco operation is canceled and the operation mode before the eco operation is entered.

  FIG. 20 is a diagram showing an operation flow of eco operation. During eco operation, if the “static” state continues for t0 in the air-cleaning operation in any of the start mode, the air purification mode, the strong deodorization mode, the humidification mode, the skin moisturizing mode, the dehumidification mode, or the dew condensation save mode A control T1 for stopping the fan motor 7 is performed. When t2 has elapsed from the stop of the fan motor 7, control is performed so that the fan motor 7 operates with "static" air volume. When the “static” state continues for t1, control T2 is performed in which the fan motor 7 stops. The air condition is detected by the odor sensor E4, the dust sensor E5, and the humidity sensor E3 even during the eco operation fan control. When each sensor reaches a preset value, the eco operation fan control is canceled, Control according to the detection result is performed. For example, when the dehumidifying operation is selected before the eco operation control, if the detection result of the humidity sensor E3 becomes a preset value during the eco operation and the humidity is determined to increase, the eco operation fan control is canceled, Perform dehumidifying operation. Alternatively, when the humidification operation is selected before the eco operation control, when the detection result of the humidity sensor E3 becomes a preset value during the eco operation and it is determined that the humidity is lowered, the eco operation fan control is canceled and the humidification is performed. Do the driving. In addition, when the air purification operation is selected before the eco operation control, when either the odor sensor E4 or the dust sensor E5 becomes a preset value during the eco operation and the air cannot be said to be in a clean state, Release the fan control and perform the air cleaning operation. When the “static” state continues for t0 after entering each state, the eco operation fan control is performed again.

  FIG. 21A is a diagram illustrating a timing chart for normal operation, and FIG. 21B is a diagram illustrating a timing chart for eco operation. t0, t1, t2, t3, and t4 represent time. In normal operation in any of the start mode, air clean mode, strong deodorization mode, humidification mode, skin moisturizing mode, dehumidification mode, and dew condensation save mode, the air volume is still and the air volume is still. Even if the air is kept clean afterwards, the operation with “static” air flow is continued. On the other hand, the eco operation is performed when the air volume “static” operation continues for t0 or more while the air is clean. The state where the air is clean is a case where the detection result of the odor sensor E4 is not more than a preset set value e4 and the detection result of the dust sensor E5 is not more than a preset value e5. When the air is in a clean state, the fan motor 7 is operated with the air volume “static”. When the “static” state continues for t0 or more, control T1 is performed in which the fan motor 7 is stopped. Thereafter, a control T2 is performed in which the fan motor 7 is operated when the air is kept clean and t2 elapses. The control T2 continues the t1 operation with the “static” air volume. After that, if the air remains clean, the control T1 is performed again after the elapse of t1. When the air is kept clean, the intermittent operation control T is repeated in which the control T1 and the control T2 are repeated. However, the air is detected by the odor sensor E4 and the dust sensor E5 even during the eco operation, and when the odor or dust is detected, the fan motor 7 operates and the air volume is switched according to the degree of air contamination. After the air volume is switched, when the air is in a clean state and the “static” air volume operation continues for t0 or more, the control T for periodically operating and stopping the fan motor 7 is performed again. When the eco operation is performed, the operation of the fan motor 7 is automatically stopped when the air is clean, leading to a reduction in power consumption. Further, when the fan motor 7 is operated by the control T2, the fan motor 7 is operated with the “quiet” air volume having the smallest air volume, which leads to a reduction in power consumption. In addition, the intermittent motion is repeated, and when t4 elapses, the power is automatically stopped and the power is turned off, which leads to further reduction in power consumption. For example, when e4 is 1 and e5 is 1, the air is clean when the detection results of the odor sensor E4 and the dust sensor E5 are 1 or less, respectively. When the detection result of either the odor sensor E4 or the dust sensor E5 is 2 or more, the control of the fan motor 7 in the eco operation is canceled, and the operation is performed with an air volume corresponding to the degree of air contamination. Become. For example, t0 to t4 can be set as t0 = 10 minutes, t1 = 10 minutes, t2 = 50 minutes, t3 = 60 minutes, and t4 = 8 hours. Therefore, after 8 hours, it automatically stops and the power is turned off, so that no further operation is performed and no extra power is consumed.

  When the self-drying button 52c on the operation panel 60 is pressed, the display on the self-drying button 52c is turned on, and the inside of the main body is dried by the air blowing operation, and the self-drying operation is performed to suppress the occurrence of mold. During the self-drying operation, the flap 2t stops in the upward direction, and the air volume becomes strong. If the self-drying operation is performed for a long time, it automatically stops and the power turns off. When the self-drying button 52c is pressed during the self-drying operation, the self-drying operation is stopped and the operation operation is waited. If no operation is performed as it is, the power is automatically turned off after a while. Alternatively, the operation is also stopped by pressing the power on / off button 51 during the self-drying operation. In that case, all the lamps are turned off and the flap 2t is closed.

  When the swing button 52d of the operation panel 60 is pressed while the swing is stopped, the flap 2t performs a swing operation that performs a reciprocating rotation between a predetermined angle and a fully open position. When the swing button 52d is pressed during the swing operation, the flap 2t stops at the pressed position.

  Further, the lamp brightness of the display unit of the operation panel 60 can be switched by pressing the swing button 52d for 3 seconds or more. Each time the swing button 52d is pressed, the brightness of the lamp is switched. Thereby, it becomes possible to drive an air cleaner in the state which suppressed the brightness of the lamp at the time of sleeping, for example.

  Each time the timer button 52e of the operation panel 60 is pressed, the 2-hour timer, 4-hour timer, and no timer are switched. The corresponding display lights up. If a 2-hour timer or 4-hour timer is selected, it automatically stops after each time of operation.

  The mode in which the heater 33 is used is a configuration in which the power-on / off button 51 is pressed once and the power is turned off to temporarily stop or stop, or the mode in which the heater 33 is used is other. The pressing time of the operation button 50 is set longer by using the time acquired from the oscillator E8 (see FIG. 5) than the mode in which the heater 33 is not used, and is not limited to the mode in which the heater 33 is easily used. And increase reliability.

  Further, it has a memory function, and when the power is turned on by pressing the power on / off button 51, the display of the operation mode when the previous operation is finished blinks. If the previous operation is left to start, the start display blinks. In the case of the previous eco operation, the vehicle is operated by the eco operation.

  When the air volume button 52a is pressed and the swing button 52d is pressed for 3 seconds or longer, the current sensor sensitivity blinks and is displayed. The sensor sensitivity can be recognized by the flashing of the indications “weak”, “medium”, and “strong” at the upper part of the air volume button 52a. The sensor sensitivity is “Low” when the airflow “low” display is flashing, the sensor sensitivity is “medium” when the airflow “medium” display is flashing, and the airflow “high” display is flashing. Sensor sensitivity is “high”. If the swing button 52d is pressed again for 3 seconds or more together with the air volume button 52a while the sensitivity display is blinking, the sensitivity is switched. Each time this operation is repeated, the sensor sensitivity is switched between “low”, “medium”, and “high”.

  As shown in FIG. 4, a button on the operation panel 60 of the air cleaner 1 that can select an air cleaning mode and a strong deodorizing mode, a button that can select a humidifying mode and a skin moisturizing mode, and a dehumidifying mode And buttons that can select the clothes drying mode and the condensation save mode are arranged and arranged in different colors. For example, the air purification button 56 is colored green, the humidification air purification button 55 is colored blue, and the dehumidification air purification button 54 is colored orange.

  Therefore, there is an effect that it is easy for the user to select a target mode. In addition, when each mode is selected, since the air volume appropriate to each mode and the wind direction by the flap are set in advance, in many cases, the user only has to select each mode. Moreover, since it is easy to derive to a similar function mode by pressing one button, it is easy to reach the target mode, and there is an effect of reducing operation errors. In addition, the same function mode can be selected with the same button, and the color of the operation button 50 of the dehumidification mode group, that is, the group that selects the mode that uses the heater 33, is different from the color of the mode that does not use the heater 33. This has the effect of preventing unintended operations such as unintended heater operation. In addition, since the mode of a similar function can be selected with the same button, the mode intended by the user is different from the operation mode of the air cleaner, and there is an effect that an erroneous operation such as unintended heater operation can be prevented.
