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 is composed of a deodorizing filter 34 in which activated carbon 33 is spread over a base material 32 having air permeability, and is folded in a horizontal direction in a zigzag manner in order to increase a dust collection 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 formed by cutting a single piece of thick paper such as 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 (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 through 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.

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 on the outer sides of the short side surfaces 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 attach the parts in advance to the bonding locations. 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 oriented in 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 the present embodiment, the filter unit 30 also becomes narrower in the mounting direction of the paper frame 36 between the same size as the filter unit mounting portion 31 and a slightly larger size. 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 configured 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.

When 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. Ready for operation.

When this air purifier is used, the manual operation button 18 on the operation display section 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 with 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 transmission section 51 for transmitting a remote control signal such as infrared rays at the distal 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 shown in the enlarged view of FIG. 17, when the slide button 57a is set to the cut side (left end side), the dirt sensor 55 and the human body sensor 56 are turned on.
Are not transmitted, the dirt sensor 55 is set to low sensitivity when set to the low side (center part), and set to high sensitivity when set to the high side (right end side). As described above, by configuring the sensor ON / OFF setting unit and the sensor sensitivity adjustment unit with the integrated switch 57, cost reduction and downsizing of the remote controller 50 can be achieved. Although the sensitivity adjustment of the human body sensor 56 is also possible, since the human body sensor 56 detects the presence or absence of a person's movement, there is not much meaning in the sensitivity adjustment. Therefore, in this embodiment, only the dirt sensor 55 is used. Sensitivity adjustment.

Also, as described above, by providing the human body sensor 56 together with the dirt sensor 55, in addition to the actual air dirt due to smoking or the like, air dirt due to dust or the like flying up due to the movement of a person is detected in advance. The room air can be efficiently and promptly purified.

Although the air purifier body 1 of the above embodiment is provided with only the dirt sensor 24 and no 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 is increased. 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. 19 is a block diagram showing a main part configuration of the remote controller 50 shown in FIGS. 16 to 18.

The remote controller 50 has a built-in control unit 59 composed of a microcomputer or the like.
When a signal indicating the degree of contamination of the air detected by the contamination sensor 55 is input, the sensor detection is invalidated if it is set to the off side in accordance with the setting of the sensor switch 57, and is set to the low side or the high side. If this is the case, the level of air contamination is determined according to the sensitivity (in this embodiment, three levels of level 1, level 2, and level 3), and a signal indicating the motion of the person detected by the human body sensor 56 is output. When an input is made, the sensor detection is invalidated if the sensor switch 57 is set to the off side, and the level of the human detection is determined otherwise. (In the present embodiment, the level is input once to five times in 30 seconds. If there is an input six times or more in 1, 30 seconds, level 2), the transmitter 51 transmits the higher of the determined dirt level and human detection level as the sensor 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. 20 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.

The control section 49 mounted on the control board 16 in the above-described upper case 7 controls the motor drive section 48 in accordance with an input from the operation section 6a to drive the fan motor 9 during manual operation.

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

FIG. 21 shows the effect of the sensitivity adjustment of the present invention in one level, in a simple and easy-to-understand manner. FIG. 9A shows a low sensitivity mode in which the sensor switch 57 is set to the low side, in which the level of the output of the dirt sensor 55 is determined at a predetermined high threshold value A. On the other hand, FIG. 7B shows a high sensitivity mode in which the sensor switch 57 is set to the high side, in which the level determination of the output of the dirt sensor 55 is performed at a predetermined low threshold value B.

As can be seen from the figure, in the low sensitivity mode (a), the remote control signal is not transmitted until the air contamination detected by the contamination sensor 55 reaches the high threshold value A. Compared with the high sensitivity mode (b) in which the remote control signal is frequently transmitted, the frequency of transmission of the remote control signal is reduced, and power consumption can be reduced.

FIG. 22 is a flowchart showing the operation of the remote controller 50 when the sensor switch 57 is set to the off side in addition to the sensitivity adjustment.

The control unit 59 of the remote controller 50 first inputs the setting state of the sensor switch 57 and detects air contamination by the contamination sensor 55 (step 101).

Next, the setting state of the sensor switch 57 is determined, and if it is set to the higher side of sensitivity adjustment (high sensitivity mode), the threshold value for level determination is shown in FIG. Such a low threshold value B is set (Y in decision 102)
→ Process 106). If the sensor value detected by the dirt sensor 55 is larger than the threshold value set above, that is, the lower threshold value B, a remote control signal is transmitted (Y in decision 107 → process 108), and the threshold is reached. If the value is equal to or less than the value B, the transmission is not performed (N in the judgment 107).

If the sensor switch 57 is set to the lower side of sensitivity adjustment (low sensitivity mode), the threshold value for level determination is set to a higher threshold value A as shown in FIG. Is set (N in decision 102 → Y in decision 103 → process 105). If the sensor value detected by the dirt sensor 55 is larger than the threshold value set above, that is, the higher threshold value A, a remote control signal is transmitted (Y in decision 107 → process 108), and the threshold is reached. If the value is equal to or smaller than the value A, the transmission is not performed (N in the judgment 107). As described above, in this low-sensitivity mode, the frequency of transmitting remote control signals is lower than in the high-sensitivity mode, and power consumption can be reduced. Therefore, if the sensor switch 57 is set to the low sensitivity mode in accordance with the use situation when there is no smoker or the preference of the user who dislikes noise due to frequent on / off of the purifier drive, the built-in battery of the remote controller 50 can be used. The service life can be extended.

On the other hand, if the sensor switch 57 is set to the off side, that is, if neither the low side nor the high side of the sensitivity adjustment, the sensor detection is invalidated and the remote control signal is not transmitted, and the process proceeds to the next processing ( N of decision 102 → N of decision 103
→ Process 104). Therefore, when the power of the main body 1 is turned off or when there is no need to clean the air, the sensor switch 57
Is set to the cut side, wasteful power consumption can be reduced, and the battery life can be further extended.

In this embodiment, a similar dirt sensor 24 is also provided on the main body 1 side. When air contamination is severe, the remote controller 50 and the main body 1 side do not change much. If the switch 57 is set to the off side and the automatic operation is performed by the dirt sensor on the main body 1 side, the frequent transmission from the remote controller 50 can be prevented, so even in such a case, the power consumption of the battery can be saved.

In the above-described embodiment, the sensor sensitivity is adjusted in two steps of the low side and the high side. Alternatively, it may be possible to flexibly respond to the preference of the user.

In the 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 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.

[0063]

As described above, according to the air purifier of the present invention, the remote controller includes a sensor for detecting a required level for purifying air, and a sensor sensitivity adjusting section for adjusting the sensitivity of the sensor. A control unit that controls not to transmit when the sensor detection level becomes insignificant with the sensitivity adjusted by the sensor sensitivity adjustment unit, so that there is a large degree of freedom in installation and a place where people are generally present When it becomes necessary to clean the air near the remote controller placed in the room, the air purifier body is driven quickly, and the air can be quickly cleaned before dust and smoke spread in the room. At the same time, by lowering the sensitivity of the sensor according to the use situation and the user's preference, the transmission frequency is reduced, so that the power consumption can be reduced and the life of the built-in battery can be extended.

Further, the remote controller is provided with a sensor for detecting a required level for purifying air, and a sensor on / off setting section for setting on / off of the sensor, and a sensor on / off setting section for setting the sensor on / off. Control unit so that the sensor detection level is not transmitted when the sensor is turned on. Since the transmission is not performed at all by setting to the off side, the life of the battery can be further extended.

Further, the provision of the sensor sensitivity adjusting section and the sensor ON / OFF setting section, and the integral configuration of these switches, can reduce the cost and the size of the remote controller.

Further, as the sensors, a dirt sensor for detecting air dirt such as smoke and reducing gas in the air and a human body sensor for detecting the movement of a person in a non-contact manner are provided. In addition to the effect, in addition to the actual air contamination due to smoking or the like, air contamination due to dust or the like soaring by 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 cleaner body side, the dirt sensor must be provided for both to detect actual air dirt. Since it is possible to indirectly detect the possibility of air contamination even from movement, there is not much need to prepare for both.Therefore, by installing it only on the remote control side where the degree of freedom of installation is large, you can reduce the air in the room without adding much cost. It can be efficiently and quickly cleaned.

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