It can be lowered.

  The flow of air when the vehicle air cleaner 1 is operated will be described with reference to FIG. The air sucked into the casing 10 from the suction port 131 by the blower 2 passes through the first passage 101 on the downstream side of the suction port 131 where the blower 2 is provided. Thereafter, the air passes through the second passage 102 provided between the back surface portion 113 and the ion generator 3, and passes through the third passage 103 that connects the second passage 102 and the outlet 132. The third passage 103 is formed between the ion generator 3 and the upper side surface 111. Since the discharge needle portion 31 is installed in the third passage 103, the air passing through the third passage 103 is blown out together with the ions generated in the discharge needle portion 31 from the outlet 132 into the vehicle interior space.

  Next, the installation position of the vehicle air cleaner 1 in the vehicle interior space will be described with reference to FIGS. 17 and 18. For example, as shown in FIG. 17, the vehicle air cleaner 1 can be installed by inserting the stay of the headrest into the ring-shaped string 8 and suspending the string 8. Alternatively, it can be installed on the armrest as shown in FIG. It can also be installed on a seat or dashboard. The vehicle air cleaner 1 can be installed in any location as long as it can be hung by the string 8 in the vehicle interior space or a location where the space for arranging the casing 10 can be secured. In addition, a bracket that can be fixed to the cup holder can be attached to the back surface portion 113 and fixed to the cup holder for installation.

  Next, the effect which the air cleaner 1 for vehicles of 1st Embodiment brings is demonstrated. The vehicle air cleaner 1 includes a blower 2 that drives air, an ion generator 3 that generates ions in the air, and a casing 10 that houses the blower 2 and the ion generator 3. The casing 10 has a shape having an upper side surface portion 111 and a lower side surface portion 112 that are a pair of side surface portions facing each other, and a front surface portion 114 that intersects the upper side surface portion 111 and the lower side surface portion 112. . The front part 114 is a part located in front of the upper side part 111 and the lower side part 112 in the front view of the casing 10, and has a larger surface area than the upper side part 111 and the lower side part 112.

  The front portion 114 is provided with a suction port 131 into which air in the passenger compartment sucked by the blower 2 is sucked in a region occupying one side with respect to the center. And in the area | region which occupies the other side with respect to the center, the blower outlet 132 from which the vehicle interior air suck | inhaled in the casing 10 from the suction inlet 131 blows off toward the vehicle interior after passing the ion generator 3 is provided.

  According to this, the air cleaner 1 for vehicles which inhales air from the front part 114 of a casing, and blows off from the front part 114 can be provided. Therefore, compared with the case where the suction inlet 131 and the outlet 132 are provided in the side surface, the distance from the inlet 131 to the blower 2 and the distance from the ion generator 3 to the outlet 132 in the front view are set shorter. can do. Therefore, it is possible to reduce the size of the casing in a front view, and it is possible to realize a more compact vehicle air cleaner. Further, the passage length in the direction from the inlet 131 to the outlet 132 in the casing 10 can be set short. Furthermore, by forming both the suction port 131 and the outlet port 132 in the front part 114, an air flow that does not easily interfere with surrounding members can be formed, so that the degree of freedom of the installation location and installation posture can be improved.

  The front portion 114 of the vehicle air cleaner 1 has a shape having a length in the longitudinal direction and a length in the short direction, the suction port 131 is formed at one end portion in the longitudinal direction, It is formed at the other end.

  According to this, the distance between the inlet 131 and the outlet 132 can be increased at the front portion 114. Therefore, compared with the case where the inlet 131 and the outlet 132 are formed close to each other, air containing ions is sucked into the inlet 131 immediately after the air is blown out from the outlet 132, and the ions are sufficiently contained in the passenger compartment. It is possible to suppress a situation that does not spread. Moreover, since the distance between the inlet 131 and the outlet 132 can be increased, the air passage in the casing 10 can be set longer. Therefore, a sufficient space for installing the blower 2 and the ion generator 3 can be ensured, so that the ventilation resistance in the casing 10 can be reduced.

  The ion generator 3 has a discharge needle portion 31 that discharges and generates ions, and the casing 10 has therein a first passage 101 in which the blower 2 is provided on the downstream side of the suction port 131. Furthermore, it has the 2nd channel | path 102 which is provided between the back surface part 113 of the casing 10 and the ion generator 3 which oppose the front part 114, and the air which passed the 1st channel | path 101 distribute | circulates.

FIG.

  According to this, it is possible to allow the air driven by the blower 2 to pass between the ion generator 3 and the back portion 113 and then to pass through the discharge needle portion 31 and blow out from the blowout port 132. . Therefore, it is possible to blow out the ions generated at the discharge needle portion 31 together with the air more efficiently than when the air is passed between the ion generator 3 and the front portion 114 and blown out from the blowout port 132. Become. Moreover, since air goes to the blower outlet 132 after passing between the ion generator 3 and the back surface part 113, it becomes possible to blow the air which blows off from the blower outlet 132 to the front in a front view more. . For this reason, it becomes possible to suppress more that the flow of the blown-out air interferes with the member in a vehicle interior.

  According to this, the switch part 42 and the USB port part 41 can be mounted on the same substrate 4 and accommodated in the casing 10. Therefore, since the switch part 42 and the USB port part 41 can be integrated on one board, the accommodation space of the board 4 in the casing 10 can be reduced as compared with the case where each is mounted on another board. As a result, the dimensions of the casing 10 can be reduced. Further, since the number of parts can be reduced as compared with the case where the switch unit 42 and the USB port unit 41 are mounted on different substrates, man-hours and material costs during manufacturing can be reduced.

  The substrate 4 is accommodated in the casing 10 in such a posture that the surface intersects the front portion 114. According to this, compared with the case where the board | substrate 4 is accommodated with the attitude | position which does not cross | intersect with respect to the front part 114, the projection area in front view can be made small. Therefore, the vertical and horizontal dimensions of the casing 10 in the front view can be reduced, and the casing 10 can be made compact.

  The casing 10 includes an inner casing 11 and an outer casing 14 that is detachably fixed to the inner casing 11. The inner casing 11 has an insertion hole portion 126 through which a part of the connector portion 52 is inserted. Have. The outer casing 14 has a notch portion 144 through which the cord portion 51 of the USB cable 5 is inserted, and is attached to the inner casing 11 so as to cover the connector portion 52 exposed to the outside of the inner casing 11.

  According to this, the connector part 52 can be accommodated inside the casing 10, and the cord part 51 can be pulled out from the notch part 144 to the outside of the casing 10. Therefore, since the connector part 52 can be protected from an external impact, it can suppress that a product breaks down and causes a malfunction by the impact. Further, since the outer casing 14 makes the connector portion 52 invisible from the outside of the casing 10, the design of the vehicle air cleaner 1 can be improved.

  The front portion 114 includes a decorative plate 15, and the decorative plate 15 is provided in front of the suction port 131 and the outlet port 132. According to this, when the vehicle air cleaner 1 is viewed from the front, it is possible to make the inside of the casing 10 invisible from the suction port 131 and the blowout port 132, so that the design of the vehicle air cleaner 1 is achieved. Can be improved.
