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 laid 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 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 the present 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 a single piece of thick paper such as coated paper into a shape as shown in a developed 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 via the fold lines 37f and 37g are short, but 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 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 affix the 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 formed of resin and requires a draft angle in molding, the filter unit mounting portion 31 is moved 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.

Then, the filter unit 30 having the above-described configuration 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 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 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 this 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 is used together with a dirt sensor 55 of the same type as the dirt sensor 24 on the main body 1 side, for example, a semiconductor gas sensor. The configured human body sensor 56 is provided. Further, the ON / OFF of the dirt sensor 55 and the human body sensor 56 and the dirt sensor 55
Sensor switch 57 with adjustable sensitivity
Also, a lamp 58 that is lit at the time of transmission to indicate that transmission is being performed during automatic sensor operation is provided. The dirt sensor 55 and the human body sensor 56 on the remote controller 50 only need to be able to detect the necessity of air purification (whether they are dirty or a person is moving). In comparison, a low-precision and low-cost one may be used.

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, and the room is detected. Air can be efficiently and promptly cleaned.

Although the air purifier 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 human body sensor 46 of the same type and high in accuracy 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 by that amount. 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 a 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.
When a signal indicating the presence or absence of air contamination detected by the dirt sensor 55 is inputted, the level of the air dirt is determined (one stage of whether or not the dirt is more than a certain level) and detected by the human body sensor 56. When a signal indicating the movement of a person is input, the level of the person detection is determined (one stage of whether or not there is a certain level of movement). Is transmitted from the transmission unit 51. When an input is received from the operation unit 52, a signal corresponding to the input is transmitted from the transmission unit 51.

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.

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

On the other hand, when automatic driving is set,
When a signal indicating the degree of dirt of air detected by the dirt sensor 24 is input, the level of air dirt is determined (three levels of level 1, level 2, and level 3 in the present embodiment).
When a signal indicating the movement of a person detected by the human body sensor 46 is input, the level of the human detection is determined (in the present embodiment, the levels 1 and 30 are input once to five times in 30 seconds).
If there are six or more inputs per second, level 2), the higher of the determined dirt level and human detection level is taken as the sensor signal level on the main body 1 side. When a remote control signal indicating the necessity of air cleaning is received from the remote controller 50, the motor drive unit 48 is controlled for a certain period of time regardless of the sensor signal level of the main body 1 to set the fan motor 9 to, for example, weak. After that, the motor drive unit 48 is controlled based on the sensor signal level of the main body 1 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, automatic operation using the sensor according to the present embodiment will be described with reference to flowcharts shown in FIGS. FIG. 20 shows a control unit 59 on the remote controller 50 side.
FIG. 21 is a flowchart of the control unit 49 on the main body 1 side.

As shown in FIG. 20, the control section 59 on the remote control side receives sensor signals from the dirt sensor 55 and the human body sensor 56, and performs simple level determination as to whether or not each of them is equal to or greater than a predetermined set value. To determine whether or not any of the sensor signal levels has changed from 0 to 1 (process 1).
01 → decision 102). If none of them has changed, the remote control signal is not transmitted (N of decision 102), and if any of them has changed, a remote control signal for driving the cleaning operation of the main body 1 is transmitted (Y of decision 102 → Y). Process 103).

On the other hand, as shown in FIG. 21, the control section 49 of the main body 1 checks whether or not a remote control signal has been received, and if so, drives the fan motor 9 for a short time. Y in decision 201 → process 202).

Then, the sensor signals of the dirt sensor 24 and the human body sensor 46 of the main body 1 are input, and the above-described level determination is performed. The higher one is set as the sensor signal level of the main body 1 and the value is checked. (Process 203 → Judgment 204, Judgment 207, Judgment 209).

If the sensor signal level is 0, it is checked whether or not a predetermined time has elapsed since the reception of the remote control signal, and if it has elapsed, the fan motor 9 driven in the weak operation is stopped ( OFF) (decision 20)
If Y has not passed, the weak driving is continued (N in decision 205 → process 20).
8).

If the sensor signal level is 1, the fan motor 9 is driven in a weak operation irrespective of whether a predetermined time has elapsed since the reception of the remote control signal (decision 204).
N → Y of judgment 207 → Processing 208).

Further, if the sensor signal level is 2,
The fan motor 9 is driven in the middle operation (N in the judgment 207 → Y in the judgment 209 → Processing 210). If it is not 2 or the maximum level is 3, the fan motor 9 is driven in the strong operation (judgment). N in 209 → process 211).

By repeating the above processing, the fan motor 9 is driven in a weak operation by the control such as the simple level determination using the low-precision dirt sensor 55 and the human body sensor 56 on the remote controller 50 side. After that, the fan motor 9 is driven by the high-precision dirt sensor 24 and the human body sensor 46 on the main body 1 side according to the maximum level of the air dirt level in the room and the human detection 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 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.

[0059]

As described above, according to the air purifier of the present invention, the remote controller is provided with a sensor for detecting the necessity of purifying air, and the necessity of air purification is detected by this sensor. A controller for transmitting a remote control signal to that effect, the air purifier body includes a sensor for detecting a required level for purifying air,
When a remote control signal indicating the necessity of air purification is received from the remote controller, the air purification operation is driven, and thereafter, a control unit that controls the air purification operation using a sensor provided in the main body is provided. As a result, since the sensor on the remote controller only drives the main body, a highly accurate sensor is not required, and control such as level determination can be simplified. It is possible to reduce the cost of the air purifier that can perform the control with high accuracy.

Further, the remote controller includes a dirt sensor for detecting air dirt 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 effects described above, in addition to actual air contamination due to smoking or the like, air contamination due to dust or the like flying up due to movement of a person is detected in advance, and the air in the room can be efficiently and promptly purified.

Further, since the dirt sensor is provided as a sensor on the air purifier main body side, the dirt sensor needs to be provided for both to detect actual air dirt. Since the possibility of air contamination can be detected indirectly even from the movement of people, there is little need to prepare for both.Therefore, by installing only on the remote control side, which has a large degree of freedom in installation, it is possible to reduce the cost of the room without increasing the cost. The air can be efficiently and quickly purified.

Further, by providing a dirt sensor and a human body sensor as sensors on the air purifier main body side, the cost is higher than the above, but a place where one of the human body sensors is not blocked by furniture or the like does not work. 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.
