Note that even if the operation is stopped by operating the off button 20, the standby state is established, and the remote control signal is accepted.

On the other hand, on the windward side (front side) of the fan case 10, a filter unit mounting portion 31 for mounting the filter unit 30 is formed.

The filter unit 30 comprises a deodorizing filter 34 in which activated carbon 33 is spread on a base material 32 having air permeability, and is folded in a horizontal direction in a zigzag manner in order to increase a dust collecting area (aeration area). Electrostatic filter 35
Are housed in a paper frame 36.

As described above, the filter frame is replaced with the paper frame 36.
As a result, an expensive felt frame as in the related art is not required, so that the material cost is reduced, and a complicated hot melt bonding process is also eliminated, so that the assembly process can be simplified,
The cost of the air purifier and the filter unit 30 can be reduced. Further, since the filter unit 30 capable of removing both dust and odor can be made into a unit with a low material cost and a simple assembling process, it is more effective.

Hereinafter, the filter unit 30 of this embodiment will be described in detail with reference to FIGS.

The filter frame 36 used in the filter unit 30 of the present embodiment is obtained by cutting one thick paper such as a coated paper into a shape as shown in a development view of FIG. Folding lines 37a to 37m are formed,
It can be assembled.

That is, the leeward side (the fan 8 side) at the time of mounting
Leeward opening surface 39a in which opening 38a to be formed is formed
The folding lines 37a are formed on the four sides of the leeward side opening surface 39a.
To the four side surfaces 40a to 40d, which are the upper, lower, left and right side walls of the filter frame 36, and one side surface 40a on the long side via a folding line 37e. A windward opening surface 39b in which an opening 38b to be the cover 3) is formed, and other folded pieces 41a to 41h for shape retention and bonding are formed.

Folding pieces 41a and 41b formed at one end of the short side surfaces 40c and 40d via the fold lines 37f and 37g are short, but the fold lines 37h and 37h are formed at the other end.
Folded pieces 41c and 41d formed through 37i are formed to have a length exceeding half of the long side, and cuts 42a and 42b are formed at positions corresponding to just half of the long side.
By fitting the 2a and 42b together, the folded pieces 41c and 41d can be connected to each other without bonding.

Further, semicircular cuts 42c and 42d are formed at the center of each of the fold pieces 41e and 41f formed through the fold lines 37j and 37k outside the short side sides 40c and 40d. , And handle pieces 43a and 43b are formed.

When an adhesive using an organic solvent is used for bonding each part, the action of the activated carbon 33 of the deodorizing filter 34 is reduced. Therefore, a double-sided adhesive tape (not shown) is used to affix the parts to the bonding parts in advance. I have to put it. Further, a dust filter 44 made of a thin translucent nonwoven fabric subjected to antibacterial processing is attached to the opening 38b of the windward opening surface 39b. By removing relatively large dust adhering to the coarse dust filter 44, the replacement cycle of the filter unit 30 can be lengthened.

The filter frame 36 formed as described above
Of the leeward side opening surface 39a on both short sides 4
0c and 40d are bent inward, and the long folded pieces 41c and 41d on one end side are bent inward,
The cuts 42a, 42b at their ends are fitted and connected, and the short folds 41a, 41 at the other end are connected.
1b is bent inward, and the folded pieces 41a, 41b
, The side surface 40b on the long side and the folded piece 41g on the outside thereof are bent inward and overlapped, respectively, and adhered. Further, the side surface 40a to which the windward opening surface 39b is connected is bent and bonded to the outside of the folding pieces 41c and 41d connected by fitting the cuts 42a and 42b.

Thus, a box-shaped filter frame 36 as shown in FIG. 8 is formed. This box-shaped filter frame 3
In FIG. 6, first, as shown in FIG. 9, a deodorizing filter 34 composed of activated carbon 33 and a base material 32 is housed, and an electrostatic filter 35 is housed thereon as shown in FIG. Then, the windward opening surface 39b on which the coarse dust filter 44 is stuck is folded back so as to cover the box body, and the short side opening edge and the long side folding piece 41h of the windward opening surface 39b are respectively shortened. Side 4
When the fold pieces 41e and 41f on Oc and 40d are adhered to the long side surface 40b, a box-shaped filter unit 30 as shown in FIG. 6 is completed. The windward opening surface 39
When bonding the folded edges 41e and 41f on the short side opening edge of b and the short side surfaces 40c and 40d, the handle pieces 43a and 43b formed on the folded pieces 41e and 41f are raised and then bonded. . FIG. 11 shows a cross-sectional view between the both handle pieces 43a and 43b of the completed filter unit 30.

As described above, the filter frame 36 made of paper is
Since the cardboard is cut into a predetermined shape and assembled, the material cost is further reduced and the assembly process can be further simplified.

Since the fan case 10 is also made of resin and requires a draft angle in molding, the filter unit mounting portion 31 is directed toward the mounting direction of the filter unit 30 as shown in FIG. It is formed so as to be narrow. That is, the width W1 of the frontmost part on the leeward side of the mounting part 31 is formed longer than the width W2 of the last part on the leeward side (W1> W2).

Therefore, in this embodiment, the filter unit 30 also becomes narrower in the mounting direction of the paper frame 36 between the same size and slightly larger size as the filter unit mounting portion 31. It is formed as follows. That is, as clearly shown in FIG. 13, the width w1 of the foremost part on the leeward side of the paper frame 36 is formed longer than the width w2 of the last part on the leeward side (w1> w2), and the leeward side of the paper frame 36 is formed. The relationship between the width w1 of the foremost part and the width W1 of the foremost part on the windward side of the mounting part 31 is w1 ≧ W1, the width w2 of the rearmost part on the leeward side of the paper frame 36 and the width W2 of the rearmost part on the leeward side of the mounting part 31. And w2 ≧ W2
The widths w1 and w2 of the paper frame body 36 are set such that the filter unit 30 does not collapse when the filter unit 30 is press-fitted into the mounting portion 31. The size is such that the body 36 can be inserted into the mounting portion 31 to the extent that the body 36 is deformed or pressed, and is generally up to 1 mm larger than the mounting portion 31.

By configuring the filter unit 30 as described above, the side surface of the filter unit 30 mounted on the filter unit mounting portion 31 of the air purifier main body 1 and the side wall of the mounting portion 31 are shown in FIG. As described above, the entire surface A is tightly and closely contacted, so that the airtightness is enhanced and the dust collection efficiency is improved. Further, the filter unit 30 can be held without a separate filter holder, so that the filter unit 30 does not easily fall off.

Although the vertical side wall of the filter unit mounting portion 31 has almost no draft as shown in FIG. 2, it is more effective to apply the same processing to the vertical width as described above. .

When the filter unit 30 constructed as described above is mounted on the air purifier main body 1, the front cover 3 is removed from the main body 1 by pressing the clamp buttons 12 provided on both sides thereof. FIG. 14 shows a front view of the main body 1 with the front cover 2 removed.

Then, the filter unit 30 having the above-described structure is mounted on the filter unit mounting portion 31 formed on the front surface of the fan case 10 as shown in FIG. 15 and the front cover 3 is attached. Ready for operation.

When using this air purifier, the manual operation button 18 on the operation display unit 6 on the front of the upper case 7 is used.
By operating the automatic operation button 19 or a similar button provided on a remote controller to be described later, the control unit mounted on the control board 16 in the upper case 7 operates to start the operation. When the operation is started, the motor 9 is driven to rotate the sirocco fan 8, and the sucked ambient air is sucked into the main body 1 through the air inlet 2 formed on almost the entire surface of the front cover 3, and the dust is filtered by the filter unit 30. In addition, smoke and smell of cigarettes are filtered and deodorized, and the purified air is discharged from the exhaust port 4 on the upper surface of the rear cover 5.

For maintenance of the filter unit 30, the front cover 3 is removed in the same manner as described above, and the filter unit 30 is pulled out by holding the handle pieces 43a and 43b formed on both sides of the paper frame 36. As a result, the filter unit 3 can be easily removed.
0 can be cleaned or replaced.

FIG. 16 is a front view showing the remote controller according to the present embodiment.

The remote controller 50 of the present embodiment is provided with a transmitter 51 for transmitting a remote control signal such as infrared rays at the tip end side, like a general remote controller. The operation unit 52 on the hand side is provided with a sensor automatic operation button 53 for automatic sensor operation and an off button 54 for stopping the operation. As the sensor, a pyroelectric infrared sensor or the like for detecting the movement of a person in a non-contact manner together with a dirt sensor 55 composed of, for example, a semiconductor gas sensor or the like, similar to the dirt sensor 24 on the main body 1 side. The configured human body sensor 56 is provided. Also, a slide-type sensor switch 57 capable of adjusting the ON / OFF of the dirt sensor 55 and the human body sensor 56 and the sensitivity of the dirt sensor 55,
A lamp 58 that is turned on during transmission is provided to indicate that transmission is being performed during automatic sensor operation.

As described above, by providing the human body sensor 56 together with the dirt sensor 55, in addition to actual air dirt due to smoking or the like, air dirt caused by dust or the like soaring due to the movement of a person is detected in advance, and the room can be detected. Air can be efficiently and promptly cleaned.

Although the air purifier main body 1 of the above embodiment is not provided with only the dirt sensor 24 but with a human body sensor, the remote controller 50 is provided at one corner of the front surface of the upper case 7 as shown in FIG. A similar human body sensor 46 may be provided. Further, the operation display section 6 of the air purifier main body 1 is provided with a dirt display lamp 47 for displaying the degree of dirt of air.

As described above, since the dirt sensors 24 and 55 and the human body sensors 46 and 56 are provided on the air purifier main body 1 side and the remote control 50 side, respectively, the cost increases. Can be detected by the other human body sensor in a place where it is not affected by furniture or the like, so that the air can be efficiently and quickly purified even in such a room.

FIG. 18 is a block diagram showing the main configuration of the remote controller 50 shown in FIGS. 16 and 17.

The remote controller 50 has a built-in control unit 59 composed of a microcomputer or the like.
9 receives a signal indicating the degree of air contamination detected by the contamination sensor 55, and performs air contamination level determination (in this embodiment, two levels, level 1 and level 2), according to the determined contamination level. The signal is transmitted from the transmission unit 51. In addition, when a signal indicating the movement of a person detected by the human body sensor 56 is input, the level of the human detection is determined (in the present embodiment, one input has a level of 1, and there are six or more inputs in 30 seconds). And level 2), the transmitting unit 51 transmits a signal corresponding to the determined human detection level. The operation unit 5
If there is an input from 2, the transmitting unit 51 transmits a signal corresponding to the input.

FIG. 19 is a block diagram showing a configuration of a main part of the air purifier main body 1 shown in FIG. Here, the above-mentioned operation display unit 6 is shown as being divided into an operation unit 6a and a display unit 6b.

A control unit 49 mounted on the control board 16 in the upper case 7 controls the motor drive unit 48 in response to an input from the operation unit 6a during manual operation, and controls the fan motor 9
Drive.

On the other hand, when the automatic driving is set,
The level determination is performed on the dirt level signal and the human detection level signal from the remote controller 50 and the input from the dirt sensor 24 and the input from the human body sensor 46 of the main body 1 which are received by the receiver 25 in the same manner as the remote controller 50. The motor drive unit 48 has the largest level among the dirt level and the human detection level.
And the fan motor 9 is automatically operated. The operation mode, the air volume, and the like are displayed on the display unit 6b.

Hereinafter, the automatic operation using the sensor according to the present embodiment will be specifically described with reference to a flowchart shown in FIG. 20 and a timing chart shown in FIG. 21A shows a change in the dirt level on the remote controller 50, FIG. 21B shows a change in the human detection level on the remote controller 50, FIG. 21C shows a change in the dirt level on the main unit 1, and FIG. 1 (e) shows a change in the human detection level, and (e) shows a change in the automatic driving level of the main body 1.

When the automatic operation is started, the control section 49 of the main body 1 inputs a dirt level signal and a human detection level signal from the remote controller 50 (steps 101 and 102).
Further, the contamination level on the main body 1 side and the human detection level are determined (steps 103 and 104).

Further, in judgments 105 to 110, the dirt level on the remote controller 50, the human detection level on the remote controller 50,
The dirt level on the main body 1 side and the human detection level on the main body 1 side are respectively compared, and the maximum levels thereof are processed 111 to 114.
At the final drive level.

If the drive level is 0 in the judgment 115, the fan motor 9 is turned off in the processing 117, and the judgment 1 is made.
If the drive level is 1 in step 16, the fan motor 9 is set to the weak operation in step 118, and if the drive level is other than 1, that is, if the drive level is 2, the fan motor 9 is set to the strong operation.

Referring to FIG. 21 as an example, a specific description will be given.
At the time t0 when the automatic operation starts, the remote controller 50 and the main body 1
Since the levels on both sides are 0, the fan motor 9 is turned off, that is, not driven (N in decision 105 → N in decision 109 → N in decision 108 → process 112 → decision 115).
Y → process 117). At the next time point t1, the remote controller 50
Since only the dirt level on the side is 1 and the others remain 0, the drive level is 1 and the fan motor 9 is driven in a weak operation (Y in decision 105 → Y in decision 106 → decision 1).
07 Y → process 113 → N of decision 115 → Y of decision 116 → process 118).

Further, at time t2, the human detection level on the remote controller 50 side was 1, but the dirt level on the remote controller 50 side was increased to 2, so that the drive level was 2, and the fan motor 9 was in a strong operation. Driven (Y in decision 105 → Y in decision 106 → Y in decision 107 → processing 113 → decision 11
N of 5 → N of decision 116 → process 119).

At time t3, both the dirt level and the human detection level on the remote controller 50 side become 0, but the human detection level on the main body 1 side becomes 1, so that the drive level becomes 1.
And the fan motor 9 is driven in a weak operation (decision 1
05 N → N in Judgment 109 → N in Judgment 108 → Process 11
2 → N in judgment 115 → Y in judgment 116 → process 118).

Then, at time t4, when the human detection level on the main body 1 side also becomes 0, the drive level also becomes 0 and the fan motor 9 is turned off, that is, stopped (decision 105).
N → N of judgment 109 → N of judgment 108 → Process 112 →
Y in decision 115 → process 117).

After the fan motor 9 is stopped, at time t5
, When the contamination level on the main body 1 side becomes 1, the drive level becomes 1 and the fan motor 9 starts operating in a weak operation (N in judgment 105 → N in judgment 109 → Y in judgment 108).
→ Processing 111 → N of Judgment 115 → Y of Judgment 116 → Processing 118) Thereafter, the same processing as described above from time t6 to time 10 is repeated.

By repeating the above-described processing, the automatic operation using the dirt sensors 24 and 55 and the human body sensors 46 and 56 of the present embodiment allows the maximum level of the dirt level of the air in the room and the human detection level. Since the fan motor 9 is driven according to the level, the air can be quickly cleaned before dust and smoke spread in the room, and the air in the room can always be kept clean.

In the above description of the automatic operation, the dirt sensors 2 are provided on the air purifier main body 1 side and the remote control 50 side, respectively.
4 and 55 and the human body sensors 46 and 56 have been described. However, as shown in FIGS. 1 to 16, the air purifier main body 1 has only the dirt sensor 24 and no human body sensor. The present invention is also applicable to the above.

In this case, the dirt sensor needs to be provided for both to detect the actual air dirt, but the human body sensor indirectly detects the possibility of air dirt even from the movement of a person at a distance. Since it is possible to provide both, it is not necessary to provide them both. Therefore, by providing them only on the remote controller 50 side where the degree of freedom of installation is large, the air in the room can be efficiently and quickly purified without increasing the cost.

In the above embodiment, the dirt sensors 24 and 55 composed of semiconductor gas sensors and the like and the human body sensors 46 and 56 composed of pyroelectric infrared sensors and the like are used. Then, for example,
It is also possible to use a dust sensor that detects the degree of contamination of the air by utilizing the irregular reflection of light due to dust, an ultraviolet (UV) sensor that detects ultraviolet light emitted from the lighter flame, and the like.

[0060]

As described above, according to the air purifier of the present invention, the air purifier includes a main body for purifying air and a remote controller for remotely operating the main body of the air purifier. Each of the remote controls has a sensor for detecting a required level for purifying air, and the air purifier main body has a sensor output level transmitted from the remote control and a sensor output level of the main body during automatic operation by the sensor. Based on the above, the control unit that controls the driving level of the main body at their maximum level is provided, so that it can be placed not only near the fixed air purifier main body but also in places where there is a large degree of freedom of installation and generally people are present Even if it becomes necessary to purify the air near the remote control, the air purifier body is driven promptly according to the degree, and before dust and smoke spread in the room. It can be quickly cleaned care.

Further, the sensor includes a dirt sensor for detecting air contamination such as smoke in the air and reducing gas, and a human body sensor for detecting the movement of a person in a non-contact manner. In addition to the actual air dirt, air dirt due to dust and the like soaring due to the movement of a person is detected in advance, and the air in the room can be efficiently and quickly cleaned.

Further, by providing a dirt sensor on the air purifier main body side and a dirt sensor and a human body sensor on the remote controller side, it is necessary to provide the dirt sensor for both actual air dirt detection. However, since the human body sensor can indirectly detect the possibility of air contamination even from the movement of a person at a distance, it is not necessary to prepare for both. In addition, the room air can be efficiently and promptly cleaned at a low cost.

Further, by providing a dirt sensor and a human body sensor on each of the air purifier main body side and the remote control side, the cost is higher than the above, but one of the human body sensors is blocked by furniture or the like. Since the movement of a person in a place where it does not occur can be detected by the other human body sensor, the air can be efficiently and quickly purified even in such a room.
