Description

  The present invention relates to a vehicle air cleaner that cleans air sucked by a fan with a filter housed in a filter housing portion and discharges the air into a vehicle.

  In recent years, weather conditions in which dust-like substances such as PM (Particulate Matter) 2.5 are included in the atmosphere have increased, and there are many cases in which health is harmed by inhaling PM2.5.

  For example, the air conditioner disclosed in Patent Document 1 is known for the dust-like substance for home use, but there is an increasing demand for cleaning the air in the vehicle. For this reason, demand for an on-vehicle type air purifier is expected.

  As a method of using an on-vehicle air purifier, it is dangerous to operate while driving a car. For this reason, it is considered that a method of switching the operation mode “automatically” according to the environment by installing a sensor for detecting dust or a sensor for detecting odor is considered to be mainstream.

However, there is a problem that the vehicle air cleaner does not work efficiently.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to adjust the amount of clean air including the stop of the fan according to the open / close state of the window of the vehicle, thereby efficiently controlling the drive. It is providing the vehicle air cleaner which can perform.

  In order to solve the above-described problems, a vehicle air cleaner according to an aspect of the present invention cleans air sucked by a fan with a filter stored in a filter storage unit and discharges the air into the vehicle. In the air cleaner, a window opening / closing state detection unit for detecting an opening / closing state of a vehicle window and a control unit for adjusting the air volume of the fan based on the opening / closing state of the vehicle window by the window opening / closing state detection unit are provided. It is characterized by having.

[Embodiment 1]
One embodiment of the present invention will be described below with reference to FIGS.

  The configuration of the vehicle air cleaner 10A of the present embodiment will be described based on FIGS. 1 (a), (b) to 3 (a), (b), and (c). Note that the configuration of the vehicle air cleaner 10A is an example, and is not necessarily limited thereto, and may take other forms. That is, in the present invention, it is sufficient that at least the filter unit 17 and the fan 15b exist in the vehicle air cleaner 10A. FIG. 1A is a plan view showing a vehicle 1 equipped with a vehicle air purifier 10A of the present embodiment. FIG. 1B is a block diagram showing the configuration of the vehicle air cleaner 10A. FIG. 2 is a perspective view showing an attachment state of the vehicle air cleaner 10A of the present embodiment. FIG. 3A is an exploded perspective view showing the configuration of the vehicle air cleaner 10A of the present embodiment. FIG. 3B is a side view showing the configuration of the vehicle air cleaner 10A. FIG. 3C is a perspective view showing the configuration of the vehicle air cleaner 10A from the back side.

  The vehicle air cleaner 10A according to the present embodiment is attached to, for example, the back surface of the passenger seat 2 of the vehicle 1 as shown in FIG.

  As shown in FIGS. 3A, 3B, and 3C, the vehicle air cleaner 10A has an outer shell composed of a main body 10a and a front panel 10b. The main body 10a has a shape such that a flat box as a whole stands vertically, and is composed of a rear shell 11 on the back side and a front shell 12 on the front side.

  A handle 13 and an air outlet 14 are formed on the upper portion of the rear shell 11. The air outlet 14 has, for example, a shape in which a plurality of vertically long slits are arranged side by side.

  Inside the rear shell 11, a blower 15 including a motor 15a and a fan 15b is disposed. Although a turbo fan is employed as the fan 15b, the type of fan is not limited to this. A propeller fan or a cross flow fan can be used.

  Further, an ion generator 20 is further provided inside the rear shell 11. However, the present invention is not necessarily limited to this, and the ion generator 20 may not be provided.

  The ion generator 20 includes ion generating elements 21 and 22 attached to the left and right corners inside the rear shell 11. The ion generating element 21 generates negative ions, while the ion generating element 22 generates positive ions.

The ion generating elements 21 and 22 ionize water vapor in the air by plasma discharge, so that H ⁺ (H ₂ O) _n (n is an arbitrary natural number) as positive ions and O ₂ ⁻ as negative ions. (H ₂ O) _m (m is an arbitrary natural number). Then, when these chemically react, hydrogen peroxide (H ₂ O ₂ ) and / or hydroxyl radicals (.OH) as active species are generated, and airborne bacteria and airborne viruses are removed from the air. It has become.

  Next, a filter storage portion 16 formed of a substantially rectangular parallelepiped recess is formed on the front surface of the front shell 12, and a filter unit 17 is stored in the filter storage portion 16.

  The filter unit 17 is configured by, for example, a rectangular deodorizing filter 17a and a rectangular dust collecting filter 17b superimposed in order. However, the present invention is not necessarily limited to this, and only one of them may be used.

  The deodorizing filter 17a has a non-woven fabric made of polyester attached to a rectangular frame, and activated carbon is uniformly distributed thereon, and a non-woven fabric made of polyester is further covered thereon. The deodorizing filter 17a serves to adsorb acetaldehyde, ammonia, acetic acid and the like which are odor components in the air.

  The dust collection filter 17b is a so-called HEPA (High Efficiency Particulate Air) filter. For example, an aggregate made of polyester / vinylon non-woven fabric is combined with a melt blown non-woven fabric processed with electric stone to make a filter medium. A frame made of a nonwoven fabric with melt is welded. The dust collection filter 17b plays a role of collecting fine dust.

  A filter holding frame 18 having a substantially rectangular lattice shape is provided on the front side of the filter storage portion 16. By attaching the filter holding frame 18 to the filter insertion / removal port 15, the filter unit 17 is prevented from falling off from the filter storage portion 16.

  The front panel 10b has a rectangular shape similar to that of the filter loading / unloading port 16a of the filter housing portion 16 in a front view, and is dimensionally larger than the filter loading / unloading port 16a. And it attaches with the predetermined clearance gap 19 with respect to the front of the front shell 12 which comprises the main body 10a, and completely covers the filter outlet 16a. As a result, an air inlet is formed by the gap 19 between the front surface of the front shell 12 and the back surface of the front panel 10b.

  The driving operation of the vehicle air cleaner 10A having the above configuration will be described.

  First, when the vehicle air cleaner 10 </ b> A is operated with the filter unit 17 set, the fan 15 b is rotated by the motor 15 a, and external air is supplied from the air inlet of the gap 19 between the front panel 10 b and the front shell 12. Is introduced. The introduced air reaches the filter unit 17 through the lattice of the filter pressing frame 18, and odorous components such as acetaldehyde, ammonia, and acetic acid are adsorbed by the deodorizing filter 17a. Next, fine dust is collected by the dust collection filter 17b, and purified air free from odor and dust is sucked into the center of the fan 15b. The air sucked into the center of the fan 15 b is blown out from the air outlet 14 formed in the upper part of the rear shell 11 to the inside of the vehicle 1.

  By the way, in such a vehicle air cleaner 10A, in the conventional “automatic” operation, the state of the air in the passenger compartment is determined based on the output results of various sensors such as a dust sensor or an odor sensor, and the air volume control is automatically performed. To do.

  However, when there is air circulation exceeding the capacity of the vehicle air cleaner 10A, such as when the window of the vehicle 1 is opened and outside air flows in, the vehicle air cleaner 10A is compared with the maximum capacity (such as “strong” operation). Even if it operates, it has the problem that 10 A of vehicle air cleaners do not work efficiently.

  Therefore, in the vehicle air cleaner 10A of the present embodiment, in order to solve this problem, the air volume is automatically adjusted according to the opening and closing of the window of the vehicle 1. A configuration of a control unit or the like that controls such a function will be described with reference to FIGS.

As shown in FIGS. 1A and 1B, the vehicle air cleaner 10A according to the present embodiment cleans the sucked air with a filter unit 17 as a filter housed in the filter housing portion 16. Release into the vehicle 1. And the air flow rate of the fan 15b is adjusted based on the opening / closing state of the window 3a-3d of the vehicle 1 by the window opening / closing state detection part WS which detects the opening / closing state of the windows 3a-3d of the vehicle 1, and the window opening / closing state detection part WS. A control unit CNT is provided.
Here, the air volume adjustment of the fan 15b based on the open / closed states of the windows 3a to 3d in the control unit CNT will be described based on FIGS. 4 (a) and 4 (b) and FIGS. 5 (a) to 5 (j). (A) of FIG. 4 is explanatory drawing which shows the opening / closing pattern of the windows 3a-3d. FIG. 4B is an explanatory diagram showing the air volume of the fan 15b corresponding to each open / closed state of the windows 3a to 3d shown in FIG. 5A to 5J are plan views showing the flow direction of the wind in the opening / closing pattern of the windows 3a to 3d shown in FIG.

  In the present embodiment, No. 4 is shown in FIGS. As shown in FIG. 1, when all the windows 3a to 3d are closed, the air volume of the fan 15b is automatically adjusted according to the result of a sensor (not shown). Here, the sensor refers to, for example, a temperature / humidity sensor, a dust sensor, or an odor sensor (not shown) provided in the vehicle air cleaner 10A.

  Next, in (a) and (b) of FIG. 2-No. As shown in FIG. 5, even when one of the windows 3a to 3d is opened, the air volume of the fan 15b is automatically adjusted according to the result of a sensor (not shown).

  Next, in (a) and (b) of FIG. 6-No. 11, when any one of the windows 3a to 3d is opened, the air volume of the fan 15b is adjusted to “weak” among the three levels of “strong”, “medium”, and “weak”. The At this time, the ion generation apparatus 20 is also adjusted to the “weak” ion generation amount among the three levels of “strong”, “medium”, and “weak”.

  The flow of the wind in this case is shown by (a)-(f) of FIG. That is, when both the front windows 3a to 3b or the rear windows 3c to 3d are open, wind enters from both the left and right sides. Further, when any one of the front windows 3a to 3b and any one of the rear windows 3c to 3d is open, the wind flows from the front side to the rear side.

  Next, in (a) and (b) of FIG. 12-No. As shown in FIG. 15, even when any one of the windows 3a to 3d is opened, the air volume of the fan 15b is adjusted to “weak” among the three levels of “strong”, “medium”, and “weak”. The At this time, the ion generation apparatus 20 is also adjusted to the “weak” ion generation amount among the three levels of “strong”, “medium”, and “weak”.

  The wind flow in this case is shown by (g) to (j) in FIG. That is, when either one of the front windows 3a to 3b and the rear windows 3c to 3d is open, the wind flows from both the left and right front sides to the rear side.

  Further, when any one of the front windows 3c to 3d and both the rear windows 3c to 3d are open, the wind flows from both the left and right sides of the rear side and from the front side to the rear side.

  Finally, in (a) and (b) of FIG. As shown in FIG. 16, when all the four windows 3a to 3d are open, the driving of the fan 15b and the ion generator 20 is stopped.

  Thereby, during the "automatic" operation of the vehicle air purifier 10A, the opening and closing of the driver seat window 3a, the passenger seat window 3b, the driver seat rear seat window 3c, and the passenger seat rear seat window 3d are detected, Regardless of the result of the odor sensor or dust sensor of the vehicle air cleaner 10A, the operation of the vehicle air cleaner 10A is switched.

  Specifically, by the combination of opening and closing of the windows 3a to 3d shown in FIGS. 4A and 4B, for example, when all the windows 3a to 3d are opened and the wind passes through the inside of the vehicle 1, The driving of the vehicle air cleaner 10A is turned off, and the driving at the “weak” state is continued in the other patterns in which the windows are opened.

  On the other hand, when all the windows 3a to 3d are closed, the operation is performed with the air flow selected by the user or the “automatic” operation mode according to the sensor result is set.

  As a result, it is possible to efficiently perform the operation stop and the air volume control in the “automatic” operation mode of the vehicle air cleaner 10 </ b> A according to the open / close state of the windows 3 a to 3 d of the vehicle 1.

  Here, as detection of opening and closing of the windows 3a to 3d, for example, the approach between the upper end of the window glass and the lower end of the window frame of the door is detected by a magnet and a Hall IC, or the contact between the upper end of the window glass and the lower end of the window frame of the door is detected. Is detected by a pressure-sensitive sensor, the approach between the upper end of the window glass and the lower end of the window frame of the door is detected by blocking light with a photo interrupter, or the wind noise when the window glass is opened is detected by a sound collecting microphone. Or a single detection method such as a method of detecting a temperature difference between the inside and outside of the vehicle 1 with a thermistor. The Hall IC is a magnetic sensor using the Hall effect. When a current is passed through the semiconductor thin film and a magnetic field is applied perpendicularly to the surface of the semiconductor thin film, a voltage is applied in each direction perpendicular to the current direction and the magnetic field direction. Based on the principle of occurrence, the opening and closing of the window glass is detected.

  In addition to the above method, for example, information in a system that the vehicle 1 originally has is received by a short-range wireless communication system such as Bluetooth (registered trademark) or Zigbee (registered trademark) or wired communication. It is also possible to do.

  As described above, in the vehicle air cleaner 10 </ b> A according to the present embodiment, the air sucked by the fan 15 b is cleaned by the filter unit 17 as a filter housed in the filter housing portion 16 and released into the vehicle 1. To do. Then, based on the open / close state of the windows 3a to 3d of the vehicle 1 by the window open / close state detector WS for detecting the open / close states of the windows 3a to 3d of the vehicle 1 and the open / close state of the windows 3a to 3d of the vehicle 1 by the window open / close state detector WS. A control unit CNT to be adjusted is provided.

  That is, in the vehicle air cleaner 10A of the present embodiment, the air volume of the fan 15b is adjusted according to the opening and closing of the windows 3a to 3d of the vehicle 1. Specifically, the open / close state of the windows 3a to 3d of the vehicle 1 is detected by the window open / close state detection unit WS, and the control unit CNT changes the open / close state of the windows 3a to 3d of the vehicle 1 by the window open / close state detection unit WS. Based on this, the air volume of the fan 15b is adjusted.

  As a result, it is possible to suppress wasteful energy consumption when it is determined that the vehicle air cleaner 10A is in a situation where it cannot work efficiently. Further, after that, when it is determined that the windows 3a to 3d are closed, the control for automatically starting the operation can be performed to clean the vehicle interior air.

  Therefore, it is possible to provide the vehicle air cleaner 10A that can adjust the amount of clean air including the stop of the fan 15b and perform efficient drive control according to the open / close state of the windows 3a to 3d of the vehicle 1. .

  That is, in the “automatic” operation mode in which the air volume is automatically adjusted based on the results of various sensors, the air volume of the vehicle air cleaner 10A can be automatically adjusted according to the opening and closing of the windows 3a to 3d of the vehicle 1. .

  In the vehicle air cleaner 10A of the present embodiment, the control unit CNT stops or re-drives the fan 15b based on the open / closed states of the windows 3a to 3d of the vehicle 1 by the window open / closed state detection unit WS. Control to do.

  Thereby, the operation stop in the “automatic” operation mode can be performed according to the open / close state of the windows 3a to 3d. Further, after that, when it is determined that all the windows 3a to 3d are closed, for example, the control to automatically start the operation by re-driving the fan 15b can be performed to clean the vehicle interior air.

  That is, according to opening and closing of the windows 3a to 3d of the vehicle 1, it is possible to automatically stop or restart until the operation of the vehicle air cleaner 10A.

  Further, the vehicle air cleaner 10 </ b> A according to the present embodiment is provided with an ion generator 20 as an ion generator that mixes positive and negative ions with clean air and discharges them into the vehicle 1.

  As a result, when the clean air is released into the vehicle 1, the ion generator 20 can efficiently release high-concentration ions for virus removal and moisture retention. Moreover, 10 A of vehicle air cleaners which can adjust the ion amount contained in the clean air to a vehicle interior according to the opening / closing state of the windows 3a-3d can be provided.

  For example, when the vehicle air cleaner 10A according to the first embodiment is attached to the rear surface of the passenger seat and the impact is applied to the front panel provided on the front surface of the main body, the front panel snaps. There is a possibility that the engagement between the fitting claw portion and the claw portion insertion recess is disengaged and the front panel falls off.

  The cause of this is considered to be that, for example, a person who gets on the rear seat of the passenger seat of the vehicle 1 often hits his / her foot on the front panel. If the snap-fitting claw part on the front panel and the claw insertion recess on the main body are disengaged, it will not only be annoying for those who get on the rear seat, but also when the body moves forward due to sudden braking etc. May cause injury by hitting the face of the vehicle air cleaner with the front panel removed.

  Therefore, the vehicle air cleaner 10B according to the present embodiment is further improved on the premise of the same mounting mechanism as that of the conventional home air conditioner disclosed in Patent Document 1.

  Specifically, as shown in FIGS. 6 (a), 6 (b), 6 (c) and 7 (a) to 7 (e), the front panel 10b has a pair of projecting pins projecting upward from the upper end. 41 and 41, and snap fit claws 42 and 42 which are arranged in the lower portion and have elasticity projecting toward the filter storage portion 16 are formed. The snap fit claw portion 42 includes an arm portion 42a having elasticity and a hook-shaped holding portion 42b formed at the tip of the arm portion 42a.

  Further, as shown in FIGS. 13A, 13B, and 13C, which will be described later, a protruding pin insertion recess 16b in which the protruding pin 41 of the front panel 10b can be inserted in a loosely fitted state at the upper portion of the filter housing portion 16. And a claw portion insertion recess 50 into which the snap fit claw portion 42 can be inserted is formed in the lower portion of the filter storage portion 16.

  For this reason, after the projecting pins 41 and 41 at the upper end of the front panel 10b are inserted into the projecting pin insertion recesses 16b and 16b of the filter housing part 16 in a loose-fitting state, the snap fit claw part 42 at the lower part of the front panel 10b is stored in the filter. The front panel 10b is pushed from the front toward the claw portion insertion recess 50 of the portion 16. As a result, the snap-fit claw portions 42 and 42 of the front panel 10 b are inserted into the claw-insertion recesses 50 and 50 of the filter storage portion 16, and the hook-shaped holding portion 42 b of the snap-fit claw portion 42 is inserted into the claw portion of the filter storage portion 16. It is locked to the elastic remaining convex portion 51 of the insertion concave portion 50.

  As a result, like the conventional home air conditioner disclosed in Patent Document 1, in the vehicle air cleaner 10B of the present embodiment, the lower portion of the front panel 10b is filtered while the front panel 10b is lifted. The front panel 10b can be applied to the filter storage portion 16 by pushing it toward the storage portion 16 side. For this reason, since the snap-fit claw portion 42 uses the elastic force to lock the hook-shaped holding portion 42b to the elastic remaining convex portion 51, the engagement is not normally released. In addition, when an impact is applied to the front panel 10b, the engagement may be released.

  Therefore, in the vehicle air cleaner 10B of the present embodiment, the following configuration is further added to the above-described configuration.

  That is, in the nail | claw part insertion recessed part 50, as shown to (a) (b) of FIG.8, FIG.9 and (a) (b) of FIG.10, the snap fitting nail | claw part 42 is made into the panel surface of the front panel 10b. When inserted in the vertical direction, an elastic remaining convex portion 51 is formed to lock the hook-shaped holding portion 42b at the tip while the elastic force remains in the arm portion 42a of the snap fit claw portion 42. Further, as shown in FIGS. 11A and 11B and FIGS. 12A, 12B, and 12C, the snap-fit claw portion 42 is elastic by moving the front panel 10b upward from the state. In order to fit in, a step-continuous recess 52 that is connected to the step 51a of the elastic remaining projection 51 is formed. Further, on the side opposite to the stepped recess 52, a recess spacing narrow projection 53 for narrowing the recess spacing of the claw insertion recess 50 is formed.

  As a result, the snap-fit claw portion 42 fitted in the stepped continuous recess 52 is moved downward in the front panel 10b by the side end being locked by the step 51a with no elastic force. It has been stopped.

  That is, in the conventional snap-fit claw portion, when the hook-shaped holding portion at the tip of the snap-fit claw portion is locked at the convex portion as the first-stage locking in the depth direction, the elasticity of the snap-fit claw portion remains. The hook-shaped holding part is locked to the convex part in a state where it is not. For this reason, for example, even if the front panel is subsequently moved upward and moved to the connecting recess, the snap-fit claw portion does not automatically fit into the connecting recess.

  On the other hand, in the present embodiment, in the first-stage locked state, the elastic force in the direction of pressing the elastic remaining convex portion 51 remains in the arm portion 42a of the snap-fit claw portion 42. For this reason, by sliding the front panel 10 b upward, the snap fit claw portion 42 is elastically fitted into the stepped continuous recess 52 at the moment when the snap fit claw portion 42 is disengaged from the step 51 a of the elastic remaining convex portion 51. As a result, the side end of the snap-fit claw portion 42 is locked as the second step locking in the vertical direction at the step 51a in a state where the elastic force is lost.

  As a result, in this embodiment, the snap-fit claw portion 42 is locked in both the direction perpendicular to the panel surface of the front panel 10b and the vertical direction of the front panel 10b. There is nothing.

  Therefore, even when a foot or the like is hit against the front panel 10b, the front panel 10b and the filter housing portion 16 can be locked in two stages to prevent inadvertent removal of the nail.

  In the present embodiment, the second stage of locking is performed by sliding upward. For this reason, in the state of being attached to the back of the driver's seat or the passenger seat, most cases when hitting a foot or the like are impacts from the bottom to the top, so the operation of intentionally removing the front panel 10b Is the opposite, and the front panel 10b does not come off from the filter housing portion 16.

  A method of attaching the front panel 10b to the filter housing 16 in the vehicle air cleaner 10B having the above-described configuration will be described with reference to FIGS. 13 (a), 13 (b), and 14 (c) and FIGS. 14 (a) and 14 (b). To do. FIG. 13A is a perspective view illustrating a state in which the front panel 10b of the vehicle air cleaner 10B according to the present embodiment is in contact with the filter housing portion 16, and is a perspective view illustrating the configuration thereof. FIG. 13B is a perspective view of a main part showing the relationship between the snap-fitting claw portion 42 of the front panel 10b of the vehicle air cleaner 10B of this embodiment and the claw portion insertion recess 50 of the filter storage portion 16. FIG. is there. FIG. 13C is a perspective view of the main part showing the relationship between the protruding pin 41 of the front panel 10b of the vehicle air cleaner 10B of the present embodiment and the protruding pin insertion recess 16b of the filter storage portion 16. 14A is a perspective view showing a state in which the snap-fit claw portion 42 of the front panel 10b is fitted in the claw portion insertion recess 50 of the filter storage portion 16. FIG. FIG. 14B is a perspective view showing a state in which the front panel 10b is slid upward from a state in which the snap-fit claw portion 42 of the front panel 10b is fitted in the claw portion insertion recess 50 of the filter storage portion 16. FIG.

  First, as shown in FIGS. 13A and 13C, after the projecting pins 41 and 41 at the upper end of the front panel 10b are inserted into the projecting pin insertion recesses 16b and 16b of the filter housing portion 16 in a loosely fitted state, 13 (a) and 13 (b) and FIG. 14 (a), the front panel 10b is placed with the snap-fit claw portion 42 at the bottom of the front panel 10b facing the claw portion insertion recess 50 of the filter storage portion 16. Push from the front. As a result, the snap-fit claw portions 42 and 42 of the front panel 10 b are inserted into the claw-insertion recesses 50 and 50 of the filter storage portion 16, and the hook-shaped holding portion 42 b of the snap-fit claw portion 42 is inserted into the claw portion of the filter storage portion 16. It is locked to the elastic remaining convex portion 51 of the insertion concave portion 50.

  Next, as shown in FIG. 14B, the front panel 10b is slid further upward. As a result, as shown in FIGS. 11A and 11B, the snap-fit claw portion 42 is elastically fitted into the stepped continuous recess 52 at the moment when the snap fit claw portion 42 is disengaged from the step 51 a of the elastic remaining convex portion 51. As a result, the side end of the snap-fit claw portion 42 is locked as the second step locking in the vertical direction at the step 51a in a state where the elastic force is lost.

  As described above, in the vehicle air cleaner 10B according to the present embodiment, the front panel 10b is detachably provided on the front surface of the filter housing portion 16 and is attached to the front panel 10b. A projecting pin 41 projecting upward from the bottom and a snap-fit claw portion 42 having elasticity and disposed at the lower portion and projecting toward the filter housing portion 16 are formed. Further, the filter housing part 16 is formed with a protruding pin insertion recessed part 16b into which the protruding pin 41 can be inserted in a loosely fitted state and a claw part inserting recessed part 50 into which the snap fit claw part 42 can be inserted. In the claw portion insertion recess 50, when the snap-fit claw portion 42 is inserted in a direction perpendicular to the panel surface of the front panel 10b, an elastic remaining that holds the hook-shaped holding portion 42b at the tip with the elastic force remaining. The step 51 is connected to the step 51a of the elastic remaining protrusion 51 so that the snap fit claw portion 42 is elastically fitted by moving the front panel 10b upward from the state. A recess 52 is formed. The snap fit claw portion 42 fitted into the elastic remaining convex portion 51 is moved downward in the front panel 10b by the side end being locked by the step 51a in a state where the elastic force is lost. It has been stopped.

  For this reason, after the protruding pin 41 at the upper end of the front panel 10b is inserted into the protruding pin insertion recess 16b of the filter housing portion 16 in a loosely fitting state, the snap fit claw portion 42 at the lower portion of the front panel 10b is inserted into the nail of the filter housing portion 16. The front panel 10b is pushed from the front toward the part insertion recess 50. As a result, the snap-fit claw portion 42 is inserted into the claw portion insertion recess 50 of the filter storage portion 16. At this time, the claw portion insertion recess 50 is formed with the elastic remaining convex portion 51, so that the hook-like holding portion 42b at the tip of the snap-fit claw portion 42 has the elastic remaining convex portion with the elastic force remaining. Locked to the part 51.

  In the present embodiment, the front panel 10b is moved upward from this state. As a result, the claw portion insertion concave portion 50 is provided with a step-continuous concave portion 52 connected to the step 51a of the elastic remaining convex portion 51, and the snap-fit claw portion 42 remains elastic. The snap fit claw portion 42 is elastically fitted into the stepped continuous recess 52 at the moment when the snap fit claw portion 42 is disengaged from the step 51 a of the elastic remaining convex portion 51. In this state, the snap-fit claw portion 42 fitted in the step-continuous recess 52 has its side end locked at the step in a state where the elastic force is lost, and thus the lower direction of the front panel 10b is lowered. Movement is prevented.

  As a result, in the present embodiment, the snap-fit claw portion 42 is locked in both the direction perpendicular to the panel surface of the front panel 10b and the vertical direction of the front panel 10b, so that the locking can be easily released. There is no.

[Embodiment 3]
The following will describe still another embodiment of the present invention with reference to FIGS. The configurations other than those described in the present embodiment are the same as those in the first embodiment and the second embodiment. For convenience of explanation, members having the same functions as those shown in the drawings of Embodiment 1 and Embodiment 2 are given the same reference numerals, and explanation thereof is omitted.

  In addition to the configuration of the vehicle air cleaner 10A of the first embodiment and the vehicle air cleaner 10B of the second embodiment, the vehicle air cleaner 10C of the present embodiment includes (a) ( As shown in b), when the fan 15b is driven, the deodorant or deodorant is isolated from the filter housing 16, while when the fan 15b is stopped driving, the deodorant or The difference is that the deodorizer is controlled so as to be opened to the filter housing 16.

  The configuration of the vehicle air cleaner 10C according to the present embodiment will be described with reference to FIGS. FIGS. 15 (a) and 15 (b) show a vehicle air cleaner 10C according to the present embodiment, in which the lid of the deodorant or deodorant placement portion is opened and closed by magnetic force. It is a perspective view which shows the structure of 10C of air cleaners.

  First, in a vehicle air cleaner, there has been a concern about secondary odors from the filter depending on the use situation. Here, the secondary odor refers to a recurring odor due to desorption of odor components from a deodorizing filter that has adsorbed malodors. Secondary odor occurs mainly when the main unit power is off. If secondary odor occurs, bad odor is generated from the vehicle air cleaner itself, or a large amount of bad odor is generated from the outlet of the vehicle air cleaner immediately after the power is turned on. It was a factor that caused discomfort.

  As a countermeasure against such secondary odor, conventionally, when the odor of the filter becomes large, the secondary odor is forcibly discharged and diffused together with the ventilation of the room. However, such a method is the same as the fundamental countermeasure against the secondary odor of the filter is not implemented.

  Therefore, in the vehicle air cleaner 10C of the present embodiment, in order to solve this problem, as shown in FIGS. 15A and 15B, the arrangement portion 60 of the vehicle air cleaner 10C includes: A deodorant 61 or a deodorizer is provided so as to be separable from the filter housing 16. In the present embodiment, it is sufficient that either one of the deodorizer 61 or the deodorizer is provided.

  The control unit CNT controls the deodorant 61 or the deodorant in the arrangement unit 60 to be isolated from the filter storage unit 16 when the fan 15b is driven, while the fan 15b is stopped. In such a case, the deodorizer 61 or the deodorizer in the arrangement unit 60 is controlled so as to be opened to the filter storage unit 16.

  Thereby, when the fan 15b is stopped driving, the deodorizer 61 or the deodorizer that absorbs the odor from the filter unit 17 is opened to the filter housing portion 16. For this reason, when the fan 15b is turned off, the bad odor generated from the filter unit 17 can be absorbed by the deodorant 61 or the deodorant disposed in the vicinity of the filter unit 17.

  Therefore, it is possible to suppress the generation of malodor from the filter unit 17 in the off state of the fan 15b, and to prevent the user from feeling uncomfortable.

  Here, various examples of the structure for isolating the deodorant 61 or the deodorizer from the filter housing 16 are shown in FIGS. 15A and 15B, FIGS. 16A and 16B, and FIG. 17A. A description will be given based on (b). 16A and 16B show that the deodorant or deodorant arrangement portion 60 and the filter storage portion 16 are separated from each other by the lid body 62 of the arrangement portion 60, and the lid body 62 is driven to open and close by the gear 64. It is a perspective view which shows the structure of 10C of vehicle air cleaners of the type to do. 17 (a) and 17 (b) show a vehicle air cleaner of a type in which the sheet-like deodorant 61a or deodorant is stretched from the storage unit 60a as the arrangement unit 60 and the deodorant 61 or deodorant is opened. It is a perspective view which shows the structure of the machine 10C.

  First, as an isolation structure for the deodorant 61 or the deodorant filter housing portion 16, as shown in FIGS. 15A and 15B, the deodorizer 61 or the deodorizer placement portion 60 and the filter housing portion 16. The structure which isolate | separates by the cover body 62 of the arrangement | positioning part 60 is mentioned.

  In this case, an electromagnet 63 is provided in the vicinity of the lid 62, and the lid 62 can be opened and closed by a magnetic force.

  Moreover, as an example in the structure which isolate | separates the arrangement | positioning part 60 of the deodorizer 61 or a deodorizing agent, and the filter storage part 16 with the cover body 62 of the arrangement | positioning part 60, as shown to (a) (b) of FIG. The lid 62 can be driven to open and close by the gear 64. In this case, a shaft of a drive motor (not shown) is connected to the gear 64, while a flat gear (not shown) that meshes with the gear 64 is provided on the lid 62. Thereby, when the fan 15b is stopped, the control unit CNT rotates the gear 64 to open the lid 62. As a result, it is possible to open the deodorizer 61 or the deodorizer of the arrangement unit 60 to the filter storage unit 16.

  In the above example, the deodorizer 61 or the deodorizer is opened to the filter storage unit 16 by opening and closing the lid 62.

  However, it is not necessarily limited to using the lid 62. For example, as shown in FIGS. 17 (a) and 17 (b), the sheet-like deodorant 61a or the deodorant can be wound and stored in roll winding portions 60a and 60b as the arrangement portions 60 provided at the upper and lower portions. It is prepared in.

  Thus, when the fan 15b is stopped, the sheet-like deodorant 61a or deodorant wound around the lower roll take-up portion 60a is, for example, threaded into the yarns 61b and 61b at the upper roll take-up portion 60b. Thus, the sheet-like deodorant 61a can be exposed by being wound up, and the sheet-like deodorant 61a can be opened to the filter housing portion 16 by extension.

  As described above, in the vehicle air cleaner 10 </ b> C of the present embodiment, the deodorant 61 or the deodorizer is provided in the disposition portion 60 that can be isolated from the filter storage portion 16. Further, the control unit CNT performs control so that the deodorant 61 or the deodorant in the arrangement unit 60 is isolated from the filter storage unit 16 when the fan 15b is driven. On the other hand, when the driving of the fan 15 b is stopped, the deodorizer 61 or the deodorizer in the arrangement unit 60 is controlled to be opened to the filter storage unit 16.

  Thereby, when the fan 15b is stopped driving, the deodorant 61 or the deodorant that absorbs the odor from the filter unit 17 is opened to the filter housing portion 16, so that the fan 15b The bad odor generated from the filter unit 17 at the time of OFF can be absorbed by the deodorant 61 or the deodorant disposed in the vicinity of the filter unit 17.

  Therefore, it is possible to suppress the generation of malodor from the filter unit 17 in the off state of the fan 15b, and to prevent the user from feeling uncomfortable.

  In particular, in the present embodiment, the deodorizer 61 or the deodorizer is provided in the arrangement portion 60 that is isolated from the filter housing portion 16 by the lid 62. Further, the control unit CNT opens the lid 62 of the arrangement unit 60 when the driving of the fan 15b is stopped, and closes the lid 62 of the arrangement unit 60 when the driving of the fan 15b is started. To do.

  Thereby, when the fan 15 b is driven, the deodorant 61 or the deodorant in the arrangement unit 60 can be easily isolated from the filter housing unit 16 by using the lid 62.

  In the present embodiment, the deodorant or deodorant is a sheet-like deodorant 61a or a sheet-like deodorant, and the sheet-like deodorant 61a or the deodorant is disposed when the fan 15b is driven. The sheet-like deodorant 61 a or the deodorant is isolated from the filter storage unit 16 by being wound and stored in a roll winding unit 60 a as the unit 60. On the other hand, when the fan 15b is off, the sheet-like deodorant 61a or deodorant is pulled out from the roll take-up part 60a, and the sheet-like deodorant 61a or deodorant is exposed to the filter storage part 16.

  Thereby, since the sheet-like deodorant 61a or deodorizer with a large installation area is used, deodorization or deodorization can be performed efficiently.

[Embodiment 4]
The following will describe still another embodiment of the present invention with reference to FIGS. The configurations other than those described in the present embodiment are the same as those in the first to third embodiments. For convenience of explanation, members having the same functions as those shown in the drawings of Embodiments 1 to 3 are given the same reference numerals, and descriptions thereof are omitted.

  In addition to the configuration of the vehicle air cleaner 10C according to the third embodiment, the vehicle air cleaner 10D according to the present embodiment has an odor sensor 70 as an odor detection unit that detects odors as shown in FIG. And the control unit CNT is different in that it controls the fan 15b to stop when the odor from the odor sensor 70 exceeds a threshold value.

  The configuration of the vehicle air cleaner 10D according to the present embodiment will be described with reference to FIGS. 18 and 19A and 19B. FIG. 18 is a perspective view showing the configuration of the vehicle air cleaner 10D of the present embodiment. (A) of FIG. 19 is a schematic diagram showing the detection contents of the odor sensor, and (b) of FIG. 19 is a flowchart showing the operation of the vehicle air cleaner 10D of the present embodiment.

  As shown in FIG. 18, the vehicle air cleaner 10 </ b> D of the present embodiment is provided with an odor sensor 70 as an odor detection unit that detects an odor. For example, as shown in FIGS. 3B and 3C, the odor sensor 70 is disposed in the vicinity of the air outlet 14 in the rear shell 11.

  The odor sensor 70 is made of a metal oxide semiconductor sensor, for example, and detects an odor by utilizing an oxidation-reduction reaction of odor molecules. Examples of odor measurement include odor components in tobacco smoke such as ammonia and acetaldehyde, odor components of hydrocarbon gases such as methane / propane gas, and SOx odor components.

  As shown in FIG. 19A, the odor sensor 70 compares the odor value of a new filter unit 17 stored in a storage device (not shown) with the current odor value.

  Then, as shown in FIG. 19B, a power switch (not shown) is used to turn on the main body power of the vehicle air purifier 10D with a threshold value, for example, 50% higher than the odor value of the new filter unit 17. Is turned on (S1). At this time, the odor sensor 70 acquires the current odor value. If the current odor value is lower than the threshold value (S2), the vehicle air cleaner 10D is turned on (S3). As a result, the fan 15b can be driven.

  On the other hand, if the current odor value is greater than or equal to the threshold when the current odor value is acquired in S1, the vehicle air cleaner 10D does not turn on the power (S5).

  Thereby, the odor of the filter unit 17 can be prevented from diffusing inside the vehicle 1.

  Thus, in the vehicle air cleaner 10D of the present embodiment, the odor sensor 70 is provided as an odor detection unit that detects the odor of the filter unit 17. In addition, the control unit CNT controls the fan 15b to stop when the odor from the odor sensor 70 exceeds a threshold value.

  Thereby, immediately after turning on the power of the fan 15b, it is possible to prevent the filter unit 17 from generating a large amount of malodor from the air outlet 14 of the vehicle air cleaner 10D and diffusing into the interior of the vehicle 1. . Further, it is possible to prompt the user to replace the filter unit 17.

[Summary]
The vehicle air cleaner 10 </ b> A according to the first aspect of the present invention is for a vehicle that cleans air sucked by the fan 15 b with a filter (filter unit 17) stored in the filter storage unit 16 and discharges it into the vehicle 1. In the air purifier, the fan 15b is based on the open / closed state detection unit WS for detecting the open / closed state of the windows 3a to 3d of the vehicle 1 and the open / closed state of the windows 3a to 3d of the vehicle 1 by the window open / closed state detection unit WS. And a control unit CNT that adjusts the air volume.

  Thus, the window opening / closing state detection unit detects the opening / closing state of the vehicle window, and the control unit adjusts the air volume of the fan based on the window opening / closing state of the vehicle by the window opening / closing state detection unit.

  As a result, it is possible to suppress wasteful energy consumption when it is determined that the vehicle air cleaner cannot operate efficiently. Further, after that, when it is determined that the window is closed, the control for automatically starting the operation can be performed to clean the vehicle interior air.

  Therefore, it is possible to provide a vehicle air purifier that can perform efficient drive control by adjusting the amount of clean air including stopping of the fan in accordance with the opening / closing state of the window of the vehicle.

As a result, the claw portion insertion concave portion is provided with a step-continuous concave portion that is connected to the step of the elastic remaining convex portion, and the snap fit claw portion retains the elastic force. Is elastically fitted into the stepped continuous recess at the moment when it deviates from the step of the elastic remaining convex portion. In this state, the snap-fit claw portion fitted in the stepped continuous recess is prevented from moving downward on the front panel by the side edge being locked at the step with the elastic force lost. Is done.

  That is, in the present invention, in the locked state as the first stage, since the elastic force in the direction of pressing the elastic remaining convex portion remains, the snap fit claw portion is elastic by sliding the front panel upward. At the moment when it deviates from the step of the remaining convex portion, it is elastically fitted into the stepped continuous concave portion. As a result, the side end of the snap-fit claw portion is locked as the second step locking in the vertical direction at the step with the elastic force lost.

  As a result, in the present invention, the snap-fit claw portion is locked both in the direction perpendicular to the panel surface of the front panel and in the vertical direction of the front panel, so that the locking is not easily released.

  Therefore, even when a foot or the like is hit against the front panel, inadvertent removal of the nail can be prevented by locking the front panel and the main body in two stages.

  The vehicle air cleaner 10C according to the fifth aspect of the present invention is an arrangement in which the deodorizer 61 or the deodorizer can be isolated from the filter housing portion 16 in the vehicle air cleaner according to any one of the first to fourth aspects. The control unit CNT controls the deodorant 61 or the deodorant in the arrangement unit 60 so that it is isolated from the filter storage unit 16 when the fan 15b is driven. On the other hand, it is preferable to control so that the deodorizer 61 or the deodorizer of the arrangement part 60 is opened to the filter storage part 16 when the fan 15b is stopped.

  As a result, when the fan is stopped, the deodorant or deodorant that absorbs the odor from the filter is opened to the filter housing, so it is generated from the filter when the fan is off. It is possible to absorb the bad odor produced by the deodorant or deodorant disposed in the vicinity of the filter.

  Therefore, it is possible to suppress the generation of bad odor from the filter in the fan off state, and to prevent the user from feeling uncomfortable.

  The vehicle air cleaner 10D according to Aspect 6 of the present invention is the vehicle air cleaner according to any one of Aspects 1 to 5, wherein the odor detector (odor sensor 70) detects the odor of the filter (filter unit 17). It is preferable that the control unit CNT controls the fan 15b to stop when the odor from the odor detection unit (odor sensor 70) exceeds a threshold value.

  In the present invention, the control unit controls the fan to stop when the odor of the filter by the odor detection unit exceeds a threshold value.

  Therefore, it is possible to prevent a large amount of bad odor from being generated from the outlet of the vehicle air purifier immediately after the fan is turned on and diffused into the vehicle. In addition, the user can be prompted to replace the filter.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the technical means disclosed in different embodiments can be appropriately combined. Such embodiments are also included in the technical scope of the present invention.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a vehicle air cleaner that cleans air sucked by a fan with a filter housed in a filter housing portion and discharges the air into a vehicle.
