The wind direction plate 13 is automatically opened and closed in the operating state of the air conditioner indoor unit 1, opens the outlet 15 in the open state, and closes the outlet 15 in the closed state. An upper suction port 16 is formed on the upper wall portion of the housing portion 11.

Inside the air conditioner indoor unit 1, a filter 17 is provided inside the front panel 12, and a blower 18 is provided near the center of the air conditioner indoor unit 1. A heat exchanger 19 is provided between the filter 17 and the blower 18, and a space is formed around the blower 18.

(Structure of filter 17)
FIG. 4 is a perspective view of the filter 17. As shown in FIG. 4, the filter 17 has a configuration in which a net unit 21 functioning as a filter is supported by a grid-like support unit (support unit) 22. In the present embodiment, a total of two filters 17 are provided in the left-right direction of the air conditioner indoor unit 1, and as shown in FIG. 2, the filters 17 are detachable from the air conditioner indoor unit 1 when the front panel 12 is open. It has become. The filter 17 is attached / detached by the user holding the grip portion 17a and sliding the filter 17 while being guided by the guide rail provided in the air conditioner indoor unit 1.

The surface of the net unit 21 of the filter 17, that is, the surface on the lower suction port 14 and the upper suction port 16 side is an adhesive surface 17b. Further, the grid-like support portion 22 is higher than the surface of the net unit 21, that is, the adhesive surface 17b, and is convex with respect to the adhesive surface 17b. The height of the grid-shaped support portion 22 is such that the adhesive surface 17b can be prevented from coming into contact with other members when the filter 17 is attached to the air conditioner indoor unit 1. The adhesive surface 17b has an adhesive force that allows insects (at least mosquitoes) adhering to the adhesive surface 17b to be captured without escaping.

In this case, the adhesive is prevented from adhering to the grid-like support portion 22. The formation of the adhesive surface 17b by such a method is suitable for forming the adhesive surface 17b with respect to the existing filter.

The color of at least the adhesive surface 17b of the filter 17 is preferably black, which is preferred by mosquitoes, in order to increase the amount of mosquitoes caught. Therefore, it is preferable to use a black adhesive as the adhesive to be applied to the net unit 21 when forming the adhesive surface 17b. It is also preferable to use a black net unit 21.

(Operation of air conditioner indoor unit 1)
In the above configuration, the operation of the air conditioner indoor unit 1 will be described below. FIG. 5 is an explanatory diagram showing an air flow during operation of the air conditioner indoor unit 1.

As shown in FIG. 5, when the air conditioner indoor unit 1 is operated, the wind direction plate 13 is opened and the blower 18 rotates. As a result, air is sucked into the insect trapping space 31 inside the air conditioner indoor unit 1 from the lower suction port 14 and the upper suction port 16. The insect trapping space 31 is a space between the filter 17, the front panel 12, and the upper wall portion of the housing portion 11. The air sucked into the insect trapping space 31 further passes through the filter 17 and the heat exchanger 19 and is taken in around the blower 18, and is blown into the room from the outlet 15 by the blower 18. When the air passes through the heat exchanger 19, it is dehumidified, cooled, or heated according to the setting state of the operation of the air conditioner.

Here, the insects sucked into the insect trapping space 31 from the lower suction port 14 and the upper suction port 16 together with the air adhere to the adhesive surface 17b of the filter 17 and are captured without passing through the filter 17.

The filter 17 having a large number of insects attached to the adhesive surface 17b is replaced with a new one before the function as the filter 17 is significantly deteriorated. In this case, the filter 17 is disposable. Alternatively, the filter 17 may be reused after being washed with water as long as it can remove insects from the adhesive surface 17b by washing with water, for example.

Further, as the filter, a filter 17 having an adhesive surface 17b is used in the season when insects appear indoors (for example, in summer), and a filter having no adhesive surface 17b is used in the season when insects do not appear indoors. As described above, it may be replaced as appropriate according to the season or the like.

Further, when the air conditioner indoor unit 1 has a configuration in which a plurality of filters can be attached, a part of the plurality of filters is a filter 17 having an adhesive surface 17b, and the remaining part is a normal filter 17 having no adhesive surface 17b. It may be a filter. These filters can be combined according to the number of insects that appear in the room, the amount of dust in the room, the season, and the installation location of the air conditioner indoor unit 1. Especially when the filter is a disposable type, the adhesive surface 17b can be used. The filter 17 can be operated efficiently.

(Advantages of air conditioner indoor unit 1)
In the air conditioner indoor unit 1, insects that have invaded the insect trapping space 31 together with air can be attached to the adhesive surface 17b of the filter 17 and captured. Therefore, the air conditioner indoor unit 1 has an insect trap function and does not require a dedicated insect trap. Further, since the filter 17 is provided with an insect trapping function in addition to the air filter function (dust removing function) originally provided, a dedicated insect trapping sheet is unnecessary, the increase in the number of parts is suppressed, and the number of parts is suppressed. There is no need for a space to install an insect trap sheet.

Further, since the filter 17 has an adhesive surface 17b on only one surface (front surface), the manufacturing cost when the adhesive is applied to the filter 17 to form the adhesive surface 17b can be reduced. Further, when the filter 17 is attached to or removed from the air conditioner indoor unit 1, the filter 17 can be placed on a table or the like with the side other than the adhesive surface 17b facing down. Good workability when handling.

Further, the grid-like support portion 22 provided on the adhesive surface 17b side of the filter 17 is higher than the adhesive surface 17b (the surface of the net unit 21) and is convex with respect to the adhesive surface 17b. Therefore, when the filter 17 is attached to and removed from the air conditioner indoor unit 1, the adhesive surface 17b is less likely to come into contact with other members. As a result, it is possible to prevent the adhesive surface 17b from adhering to other members and deteriorating the workability of attaching and detaching the filter 17.

Further, dust and insects caught by the filter 17 are attached to the adhesive surface 17b. Therefore, when the filter 17 is removed from the air conditioner indoor unit 1 for replacement of the filter 17 or the like, dust and insects are unlikely to fall from the filter 17, which is hygienic.

(Operation of air conditioner indoor unit 2)
In the above configuration, when the air conditioner indoor unit 2 is operated, the wind direction plate 13 is opened, and the rotation of the blower 18 causes air to be sucked into the insect trapping space 31 inside the air conditioner indoor unit 2 from the upper suction port 16. The insects sucked into the insect trapping space 31 together with the air adhere to the adhesive surface 42b of the filter 42 and are captured as in the case of the air conditioner indoor unit 1.

Here, in the conventional air conditioner indoor unit having the automatic filter cleaning unit 41, the automatic filter cleaning unit 41 automatically operates at the instruction from the user by the remote control operation and, for example, at the end of the operation of the air conditioner indoor unit 2. It is set to operate). However, when the automatic filter cleaning unit 41 operates, the front brush 51 sticks to the adhesive surface 42b of the filter 42, which causes a failure of the automatic filter cleaning unit 41 or the air conditioner indoor unit 2. Therefore, when the filter 42 having the adhesive surface 42b is used, it is necessary to set the automatic filter cleaning unit 41 to not operate (inoperable setting).

Therefore, in the air conditioner indoor unit 2, the inoperability of the automatic filter cleaning unit 41 can be set by, for example, operating a remote controller. Specifically, when the automatic filter cleaning unit 41 is set to be inoperable by the remote controller, the control unit 57 saves the setting. In this case, the inoperable setting includes the operation instruction of the automatic filter cleaning unit 41 from the remote controller and the operation setting of the automatic automatic filter cleaning unit 41 (for example, the automatic automatic filter cleaning unit at the end of the operation of the air conditioner indoor unit 2). Priority is given to the operation setting of 41). Therefore, when the inoperability setting is made, the control unit 57 does not operate the automatic filter cleaning unit 41 based on the instruction from the remote controller and does not operate the automatic filter cleaning unit 41. Other operations of the air conditioner indoor unit 2 are the same as the operations of the air conditioner indoor unit 1 described above.

(Advantages of air conditioner indoor unit 2)
In the air conditioner indoor unit 2 provided with the automatic filter cleaning unit 41, the automatic filter cleaning unit 41 can be set not to operate when the filter 42 having the adhesive surface 42b is used.

The other advantages of the air conditioner indoor unit 2 are the same as the advantages of the air conditioner indoor unit 1 described above.

In this embodiment, the automatic filter cleaning unit 41 has been described by taking as an example a brush type that uses a brush to write down dust on the surface of the filter. However, the automatic filter cleaning unit 41 is not limited to this, and may be a suction type that sucks and removes dust on the surface of the filter, for example, with a small vacuum cleaner. That is, even if the automatic filter cleaning unit 41 is a suction type, the dust suction port sticks to the adhesive surface 17b of the filter 17, so that the same problem as that of the brush type occurs.

[Embodiment 3]
Still other embodiments of the present invention will be described below with reference to the drawings. For convenience of explanation, the same reference numerals will be added to the members having the same functions as the members described in the above-described embodiment, and the description thereof will be omitted.

(Operation of air conditioner indoor unit 3)
In the above configuration, when the air conditioner indoor unit 3 is operated, the insects sucked into the insect trapping space 31 together with the air adhere to the adhesive surface 43b of the filter 43 and are captured as in the air conditioner indoor unit 1.

Here, when the automatic filter cleaning unit 41 operates, the filter feeding unit 55 rotates together with the rear surface portion brush 52 (see FIG. 8). However, since the meshing convex portion 42c is not formed on the back surface of the filter 43, the filter 43 does not move even if the filter feeding portion 55 rotates. Therefore, the filter 43 is not cleaned by the automatic filter cleaning unit 41. Other operations of the air conditioner indoor unit 3 are the same as the operations of the air conditioner indoor unit 1 described above.

(Advantages of air conditioner indoor unit 3)
In the air conditioner indoor unit 3, since the filter 43 does not have the meshing convex portion 42c, the filter 43 does not move even when the automatic filter cleaning unit 41 operates. Therefore, when the automatic filter cleaning unit 41 operates, the automatic filter cleaning unit 41 or the air conditioner indoor unit 3 is prevented from being damaged due to the front brush 51 of the automatic filter cleaning unit 41 sticking to the adhesive surface 43b of the filter 43. be able to.

A filter that does not have the adhesive surface 43b and has the meshing convex portion 42c may be used. In this case, the automatic filter cleaning unit 41 can be effectively used in the season when insects do not appear in the room.

[Embodiment 4]
Still other embodiments of the present invention will be described below with reference to the drawings. For convenience of explanation, the same reference numerals will be added to the members having the same functions as the members described in the above-described embodiment, and the description thereof will be omitted. In this embodiment, a case where the blower is an air purifier will be described.

(Structure of air purifier 4 and pre-filter 62)
FIG. 11 is an exploded perspective view of the air purifier 4 which is the blower of the embodiment when viewed from the rear side. FIG. 12 is a vertical cross-sectional view of the air purifier 4 shown in FIG.

As shown in FIGS. 11 and 12, the air purifier 4 has a back panel 61 on the back surface, and a pre-filter (filter) 62 and a collection of pre-filters (filters) 62 inside the housing 66 from the back side to the front side. It includes a dust filter 63, a humidifying filter 64, and a blower 65.

The back panel 61 has a large number of suction ports 61a. Like the filter 17, the pre-filter 62 has a configuration in which a net unit functioning as a filter is supported by a grid-like support portion, and the back surface, that is, the surface on the suction port 61a side is an adhesive surface 62b. An insect trapping space 31 is formed between the back panel 61 and the pre-filter 62. An outlet 66a is formed in a portion of the housing 66 located above the blower 65.

The pre-filter 62 and the dust collection filter 63 can be removed from the housing 66 by removing the back panel 61.

(Operation of air purifier 4)
In the above configuration, when the air purifier 4 is operated, the blower 65 rotates, so that the air outside the machine is sucked into the insect trapping space 31 from the suction port 61a of the back panel 61. This air passes through the pre-filter 62, the dust collecting filter 63, and the humidifying filter 64, and then is discharged to the outside of the machine from the outlet 66a. Similar to the air conditioner indoor unit 1, the insects sucked into the insect trapping space 31 together with the air adhere to the adhesive surface 62b of the prefilter 62 and are captured.

The replacement of the filter 42 when a large number of insects adhere to the adhesive surface 42b of the filter 42, the reuse of the filter 42 by washing with water, and the replacement of the filter 42 according to the season are the same as in the case of the filter 17 described above. ..

(Advantages of air purifier 4)
In the air purifier 4, as in the case of the air conditioner indoor unit 1, insects that have invaded the insect trapping space 31 together with air can be attached to the adhesive surface 42b of the filter 42 and captured. Therefore, the air purifier 4 has an insect trap function and does not require a dedicated insect trap. The other advantages of the air purifier 4 are the same as the advantages of the air conditioner indoor unit 1 described above.

[Embodiment 5]
Still other embodiments of the present invention will be described below with reference to the drawings. For convenience of explanation, the same reference numerals will be added to the members having the same functions as the members described in the above-described embodiment, and the description thereof will be omitted.

(Configuration of air conditioner indoor unit 5)
FIG. 13 is a block diagram showing a configuration of a filter replacement required notification device 71 included in the air conditioner indoor unit 5 which is the blower device of the present embodiment.

(Configuration of air conditioner indoor unit 5 and filter replacement notification device 71)
The air conditioner indoor unit 5 of the present embodiment has, for example, the same configuration as the air conditioner indoor unit 1 (see FIGS. 1 to 5), and further includes a filter replacement notification device 71 shown in FIG. The filter replacement notification device 71 includes an input unit 72, a main body control unit 73, and a display unit 74.

The input unit 72 is, for example, a remote controller for operating the air conditioner indoor unit 1, and transmits various operation instructions to the air conditioner indoor unit 1 (main body control unit 73) in response to the user's operation. The input unit 72 includes, for example, a display unit 72a composed of a liquid crystal display device and an input side control unit 72b that controls the display of the display unit 72a.

The main body control unit 73 communicates with the input unit 72 and controls various operations of the air conditioner indoor unit 1 in response to an instruction input to the input unit 72. The main body control unit 73 includes a setting storage unit 73a, a counter 73b, and a notification control unit 73c.

The setting storage unit 73a stores the information set for the air conditioner indoor unit 1. Here, the replacement operation time, which is the accumulated time of the operation time for which the filter 17 should be replaced, is stored. The counter 73b counts the integrated operation time of the air conditioner indoor unit 1 from the time when the filter 17 is replaced. The notification control unit 73c determines whether or not the count time of the counter 73b has reached the replacement operation time of the filter 17. Further, when it is determined that the count time of the counter 73b has reached the replacement operation time, the notification control unit 73c transmits exchange instruction information indicating that the filter 17 should be replaced to the input unit 72. Further, the notification control unit 73c causes the display unit 74 to display a notification that the filter 17 should be replaced.

The display unit 74 is controlled by the main body control unit 73 to display that the filter 17 should be replaced. The display unit 74 may be, for example, a simple lamp (for example, an LED lamp) provided on the front surface of the housing portion 11 of the air conditioner indoor unit 1.

Further, when the input side control unit 72b of the input unit 72 receives the exchange instruction information from the main body control unit 73, the input side control unit 72b causes the display unit 72a to display a message prompting the user to replace the filter 17.

Here, the setting storage unit 73a stores a relatively short first replacement operation time and a relatively long second replacement operation time as the replacement operation time. The first replacement operation time is the operation time selected during the period when insects are likely to appear in the room, and the second replacement operation time is the operation time selected during the other period. Here, the period during which insects are likely to appear indoors is the summer season. The notification control unit 73c selects the first replacement operation time in the summer and the second replacement operation time other than the summer as the replacement operation time, and performs the above determination operation. This is because, in the summer when insects are likely to appear indoors, the amount of insects captured on the adhesive surface 17b of the filter 17 increases, and as a result, the life of the filter 17 is shortened.

The selection of the first replacement operation time or the second replacement operation time is selected by the input unit 72 based on the inquiry message displayed on the display unit 72a of the input unit 72 after the filter 17 is replaced. You may be able to do it. In this case, for example, the replacement operation time is set by the following procedure.

That is, the main body control unit 73 transmits information to the effect that the filter 17 has been exchanged to the input unit 72, and when the input unit 72 receives the information, the input side control unit 72b makes the above inquiry to the display unit 72a. Display a message. After that, the input unit 72 transmits the selection result of the replacement operation time required by the user in the input unit 72 to the main body control unit 73. When the main body control unit 73 receives the selection result of the replacement required operation time from the input unit 72, the notification control unit 73c sets the selected replacement operation time.

In addition, here, the period for which the relatively short first replacement operation time should be selected is explained as summer, but since the period during which insects are likely to appear in the room varies depending on the area, an air conditioner (air conditioner indoor unit 5) is used. It may be set appropriately according to the area to be used.

The main body control unit 73 indicates that the filter 17 has been replaced by an input from the input unit 72 operated by the user, or an input from a sensor provided at the position where the filter 17 is arranged to detect the removal operation of the filter 17. Alternatively, it may be known by the on / off operation of the switch that is operated by attaching / detaching the filter 17.

Further, it is possible to detect whether the filter attached by replacement is a filter 17 having an adhesive surface 17b or a filter having no adhesive surface 17b by a sensor, a switch, or the like, and the detection result is the main body. It may be possible to input to the control unit 73.

In this case, for example, the two filters may be distinguished by a special shape of a part of the filter so that the sensor, the switch, or the like can detect the special shape.

(Operation of filter replacement notification device 71)
In the above configuration, the operation of the filter replacement notification device 71 will be described below. FIG. 14 is a flowchart showing the operation of the filter replacement notification device 71.

When the filter 17 is replaced, the filter replacement notification device 71 starts a monitoring operation of the replaced new filter 17. When the filter replacement required notification device 71 starts operating, the notification control unit 73c of the main body control unit 73 determines whether the season is summer (S11). This determination is performed based on, for example, information from a timer (clock for measuring the date) provided in the notification control unit 73c. As a result of the determination, the notification control unit 73c selects the first replacement operation time with a short set time if the season is summer (S12). On the other hand, if the season is not summer, the second replacement operation time with a long set time is selected (S13).

Next, the counter 73b of the main body control unit 73 integrates and counts the operating time of the air conditioner indoor unit 5 (counts the integrated operating time) (S14).

The notification control unit 73c of the main body control unit 73 determines whether or not the integrated operation time of the air conditioner indoor unit 5 indicated by the counter 73b has reached the selected replacement operation time (S15), and the integrated operation time requires replacement operation. If the time has not been reached, the operation returns to the operation of S14.

On the other hand, as a result of the determination in S15, if the integrated operation time has reached the replacement operation time, the notification control unit 73c drives the display unit 74 to indicate that the filter 17 needs to be replaced. To do. Further, the notification control unit 73c transmits exchange instruction information indicating that the filter 17 should be exchanged to the input unit 72 (S16).

When the input unit 72 receives the exchange instruction information from the main body control unit 73, the input side control unit 72b exchange instruction information and a message prompting the user to exchange the filter 17 are displayed on the display unit 72a.

After that, when the filter 17 is replaced (S17), the notification control unit 73c of the main body control unit 73 resets the counter 73b and returns to the process of S11.

The filter replacement notification device 71 shown in the present embodiment can be applied not only to the air conditioner indoor unit 1 but also to the air conditioner indoor units 2 to 3 and the air purifier 4 described above. Further, in the air conditioner indoor unit 3 (see FIG. 7), the input unit 58 (for example, the remote controller) shown in FIG. 9 has the function of the input unit 72 of the filter replacement required notification device 71, and the control unit 57 controls the main body. The part 73 may also be used.

(Advantages of air conditioner indoor unit 5)
In the air conditioner indoor unit 5, when the operation time of the air conditioner indoor unit 5 reaches the replacement operation time of the filter 17, the display unit 74 provided in the air conditioner indoor unit 5 and the input unit 72, for example, the display unit 72a of the remote controller , The user can be informed that the filter 17 needs to be replaced.

Further, as for the replacement operation time, a relatively short first replacement operation time or a relatively long second replacement operation time can be selected. Therefore, the function of the filter 17 as an air filter and the function of capturing insects by the filter 17 can be appropriately maintained and exerted during the period when many insects are present in the room and the period when the number of insects is not present. The other advantages of the air conditioner indoor unit 5 are the same as the advantages of the air conditioner indoor unit 1 described above.

[Embodiment 6]
Still other embodiments of the present invention will be described below with reference to the drawings. For convenience of explanation, the same reference numerals will be added to the members having the same functions as the members described in the above-described embodiment, and the description thereof will be omitted.

In the above embodiment, for example, in the filter 17, an example is shown in which the adhesive surface 17b is formed by applying the adhesive to the front surface (one side) of the filter 17. However, the adhesive surface 17b may be formed by forming the net unit 21 with an adhesive material.

As the material for forming the net unit 21, for example, a material similar to the material of the adhesive roller used for cleaning the carpet can be used. For example, sticky silicone or thermoplastic elastomer. Such materials can be washed with water and regained their stickiness when dried.

FIG. 15 is a vertical cross-sectional view showing a filter 44 formed of the adhesive material of the present embodiment. The filter 44 has grid-like support portions 22 on both sides of the net portion 21. Both sides of the net unit 21 have adhesive surfaces 44b. The lattice-shaped support portions 22 on both sides are higher than the surface of the net unit 21, that is, the adhesive surface 44b, and are convex with respect to the adhesive surface 44b. The height of the grid-like support portion 22 is a height that can prevent the adhesive surface 44b from coming into contact with other members when the filter 44 is attached to the blower device, as in the case described above.

The net unit 21 of the filter 44 has an advantage that the step of applying the adhesive to the net unit 21 is unnecessary because the material itself forming the net unit 21 has adhesiveness.

The configuration of the filter 44 in which the net unit 21 is formed of the adhesive material is also applicable to each of the filters shown in the above embodiments.

[Summary]
The blower device (air conditioner indoor units 1 to 3, 5 and air purifier 4) according to the first aspect of the present invention has an air suction port (lower suction port 14, upper suction port 16, suction port 61a) and an air outlet. Ports 15, 66a, filters (filters 17, 42 to 44, pre-filter 62), and blowers 18, 65 are provided, and the air sucked from the suction ports presses the filter by the operation of the blowers 18, 65. In the blower device that passes through and is blown out from the outlet, the surfaces of the filter on the suction port side are adhesive surfaces 17b, 42b, 43b, 44b, 62a.

According to the above configuration, when the blower is operated, the air sucked from the suction port passes through the filter and is blown out from the blow port by the operation of the blowers 18 and 65. In this case, the insects near the blower can be sucked into the inside of the blower together with the air from the suction port, attached to the adhesive surface of the filter, and captured.

Therefore, the blower has an insect trap function and does not require a dedicated insect trap. Further, since the filter is provided with an insect trapping function in addition to the original air filter function (dust removal function), a dedicated insect trapping member (for example, an insect trapping sheet having an adhesive surface) is not required, and the number of parts is increased. It suppresses the increase and does not require a space for providing an insect trapping member.

In addition, since the dust and insects caught by the filter adhere to the adhesive surface, it is hygienic because the dust and insects do not easily fall from the filter when the filter is removed from the blower for replacement of the filter or the like. ..

In the blower device (air conditioner indoor units 1 to 3, 5 and air purifier 4) according to the second aspect of the present invention, it is necessary to replace the filters (filters 17, 42 to 44, pre-filter 62) in the above aspect 1. A setting for storing a notification unit (display unit 74, display unit 72a) for notifying that there is a presence, and a first replacement operation time as the replacement operation time and a second replacement operation time longer than the first replacement operation time. The storage unit 73a, the counter 73b that counts the integrated operation time of the blower device from the time when the filter is replaced, and the first time required for replacement of the filter during the first period, which is a period with many insects, are required. The second replacement operation time is selected in the second period in which the replacement operation time is selected and the period is set to be less insect-free, and when the integrated operation time reaches the selected replacement operation time, the said It is provided with a notification control unit 73c for operating the notification unit.

According to the above configuration, the notification control unit 73c operates the notification unit when the integrated operation time of the blower device from the time of filter replacement reaches the replacement operation time. Therefore, the user can know that the filter needs to be replaced by the operation of the notification unit.

Further, the notification control unit 73c selects the first replacement operation time for the first period (for example, the summer period) as the period with many insects, and sets the second period (for example, other than summer) as the period with few insects. The second replacement operation time is selected for (period). Therefore, during the period when there are many insects, the time until the filter needs to be replaced becomes short, and during the period when there are few insects, the time until the filter needs to be replaced becomes long. As a result, the function of the filter as an air filter and the function of capturing insects by the filter can be appropriately maintained and exerted during the period when many insects are present in the room and the period when the insects are not present.

The blower device (air conditioner indoor units 1 to 3, 5 and air purifier 4) according to the third aspect of the present invention is the adhesion of the filter (filters 17, 42 to 44, pre-filter 62) in the above aspect 1 or 2. The surfaces 17b, 42b, 43b, 44b, 62a are black.

According to the above configuration, the adhesive surface of the filter is formed, for example, by applying a black adhesive, which is the black color preferred by mosquitoes. Therefore, it is particularly easy to attract mosquitoes to the adhesive surface, and it is possible to provide a high catching function for mosquitoes.

In the blower device (air conditioner indoor unit 2) according to the fourth aspect of the present invention, in any one of the above aspects 1 to 3, the cleaning member (front brush 51, rear brush 52) comes into contact with the surface of the filter 42. The control unit 57 includes an automatic filter cleaning unit 41 that cleans the surface of the filter 42, a control unit 57 that controls the operation of the automatic filter cleaning unit 41, and an input unit 58 for the control unit 57. When an input intended to stop the operation of the automatic filter cleaning unit 41 is made from the input unit 58, the operation of the automatic filter cleaning unit 41 is stopped in preference to the operation instruction to the automatic filter cleaning unit 41.

According to the above configuration, when an input intended to stop the operation of the automatic filter cleaning unit 41 is made from the input unit 58, the control unit 57 gives priority to an operation instruction to the automatic filter cleaning unit 41 to perform an automatic filter. Since the operation of the cleaning unit 41 is stopped, it is possible to prevent a situation in which the automatic filter cleaning unit 41 or the blower device breaks down.

The automatic filter cleaning unit 41 operates so as to write down the dust adhering to the surface of the filter by, for example, a cleaning member that comes into contact with the surface of the filter. The control unit 57 normally cleans the automatic filter according to a setting (operation instruction) for operating the automatic filter cleaning unit 41 when the blower stops operating, or from an input unit 58 (for example, a remote controller operated by the user). When the operation instruction of the unit 41 is input, the automatic filter cleaning unit 41 is operated.

On the other hand, when the control unit 57 inputs an instruction to stop the operation of the automatic filter cleaning unit 41 from the input unit 58 (for example, a remote controller operated by the user), the control unit 57 automatically gives priority to the operation instruction to the automatic filter cleaning unit 41. The operation of the filter cleaning unit 41 is stopped. In this case, the operation stop instruction is generated when the user attaches the filter 44 having the adhesive surface 42b to the blower, operates the remote controller, and sends the operation stop instruction of the automatic filter cleaning unit 41 to the blower. It is a thing.

Alternatively, when the sensor as the input unit 58 detects, for example, that the filter 44 having the adhesive surface 42b is attached to the blower, the control unit 57 is an input intended to stop the operation of the automatic filter cleaning unit 41. ), The operation of the automatic filter cleaning unit 41 is stopped in preference to the operation instruction to the automatic filter cleaning unit 41.

Therefore, in a state where the filter 44 having the adhesive surface 42b is attached to the blower, the automatic filter cleaning unit 41 operates and the cleaning member sticks to the adhesive surface 42b, causing the automatic filter cleaning unit 41 or the blower to fail. The situation can be prevented.

In the blower device (air conditioner indoor unit 3) according to the fifth aspect of the present invention, in any one of the first to third aspects, the filter 42 having the adhesive surface 42b has meshing portions (meshing convex portions 42c) on both side portions. ), And the filter having no adhesive surface 42b has the meshing portions (engagement convex portions 42c) on both side portions, and both of these filters can be exchanged and used. A cleaning member (front brush 51, rear brush 52) that comes into contact with the filter feeding unit 55 that meshes with the meshing portion and feeds the filter, and the surface of the filter that is fed by the filter feeding unit 55 to clean the surface of the filter. ) Is provided with an automatic filter cleaning unit 41.

According to the above configuration, since the filter 42 having the adhesive surface 42b does not have the meshing portion, it is not sent by the filter feeding unit 55 of the automatic filter cleaning unit 41, and the automatic filter cleaning unit 41 operates. But it doesn't move. Therefore, it is possible to prevent a situation in which the cleaning member of the automatic filter cleaning unit 41 sticks to the adhesive surface 42b of the filter 42 and the automatic filter cleaning unit 41 or the blower device breaks down.

The blower device (air conditioner indoor units 1 to 3, 5 and air purifier 4) according to the sixth aspect of the present invention is the filter (filters 17, 42 to 44, pre-filter) in any one of the above aspects 1 to 5. 62) has the adhesive surfaces 17b, 42b, 43b, 44b, 62a only on the surface on the air suction port (lower suction port 14, upper suction port 16, suction port 61a) side.

According to the above configuration, the filter has an adhesive surface only on the surface on the air suction port side, and only one surface is an adhesive surface. Therefore, it is possible to reduce the manufacturing cost when the pressure-sensitive adhesive is applied to the filter to form the pressure-sensitive adhesive surface. In addition, when installing or removing the filter from the blower, the filter can be placed on a table or the like with the side other than the adhesive surface facing down, so workability when handling the filter is improved. Good.

In the blower device (air conditioner indoor units 1 to 3, 5 and air purifier 4) according to the seventh aspect of the present invention, the filter (filters 17, 42 to 44) is in any one of the above aspects 1 to 6. A net unit 21 having the adhesive surfaces 17b, 42b, 43b, 44b and a support unit (lattice support unit 22) provided on the adhesive surface side to support the net unit 21 are provided, and the support unit is provided. It has a height that projects from the adhesive surface and prevents the adhesive surface from coming into contact with other members when the filter is attached to the blower.

According to the above configuration, the support portion 22 of the filter protrudes from the adhesive surface and has a height that prevents the adhesive surface from coming into contact with other members when the filter is attached to the blower. Therefore, when the filter 17 is attached to and removed from the blower, it is possible to prevent a situation in which the adhesive surface adheres to other members and the workability is deteriorated.
