Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of an on-vehicle air purifier installed on a rear tray portion of an automobile.

[0002]

[Prior Art]

 In recent years, the number of vehicle air purifiers that purify the smoke and odor of cigarettes in automobiles has increased, and it is becoming common to mount them on the rear tray.

Conventionally, an in-vehicle air purifier installed on a rear tray portion of this type has an empty space by arranging a filter, a motor to which a fan is fixed, etc. in a box body formed by an upper body and a lower body. An air purifier body is formed, and a lid body having a buckle is detachably disposed on the upper body, and a body body is a lid body. In both cases, the buckle was unlocked, the lid was removed, the filter inside the main body was maintained, and at the same time, the projection switch of the lid was used to open the power switch that was closed.

[0004]

[Problems to be solved by the device]

 In such a conventional vehicle air purifier, the shape of the lid is determined as an external design element. If it also serves as the upper body, it can be constructed at low cost. In such a configuration, as the lid approaches the shape that covers the upper surface of the upper body and also serves as the upper body, the buckle provided on the lid moves from the upper surface to the dividing line from the lower body, that is, to the side surface side. To do. Therefore, the buckle on the upper surface, which can be opened and closed by moving it from above with a finger in a flat shape, has the structure in which it is pushed by the finger on the side surface to be unlocked and attached by the biasing spring. On the other hand, the other end support piece of the biasing spring formed on the lid made of resin molded product is difficult to obtain sufficient strength to prevent sink marks that damage the appearance at the time of molding, and it is difficult to obtain the temperature under direct sunlight in summer. Due to the decrease in strength due to the increase in the height, it was forced to take measures such as using a reinforcing member, which made the buckle attachment part complicated and expensive, which was a problem.

In addition, the lid that also serves as the upper body does not displace the biasing spring just by placing it on the body, and the buckle is not engaged, that is, the lid is normally attached to the body. Without it, the protrusion would cause the inconvenience of closing the power switch and driving the motor.

The present invention solves the above-mentioned problems, and provides inexpensive and easy strength of the other end support piece of the spring without using a reinforcing member or the like for the buckle mounting portion of the lid made of a resin molded product. The first purpose is to allow it.

A second object is to prevent the protrusion from closing the power switch when the lid is not properly attached to the main body.

[0008]

[Means for Solving the Problems]

 In order to achieve the first object, the present invention forms a vortex chamber for accommodating a fan with a lower body, and a partition wall on which a filter is mounted on the other end of the biasing spring formed on the lid body. The first problem solving means is that the receiving rib is formed so as to face the supporting piece.

Also, the partition wall and the buckle are engaged with each other, the lower part of the engaging piece of the buckle is set to be long, and the lid placed on the main body is lifted, and the protrusion of the lid closes the power switch. The second problem solving means is that it is not set.

[0010]

[Action]

 According to the first problem-solving means described above, the present invention provides a support piece for a lid body that is pressed by the biasing spring by a receiving rib formed on a partition wall facing the other end support piece of the biasing spring formed on the lid body. Can be prevented from deformation. Therefore, the strength of the other end supporting piece of the spring can be easily provided at low cost without using a reinforcing member or the like in the buckle mounting portion of the lid made of a resin molded product.

Further, according to the second problem solving means, the lower part of the locking piece of the buckle is set to be long and the lid body placed on the main body is lifted up, and the lid body is not normally attached to the main body. It is possible to eliminate the inconvenience that the protrusion closes the power switch to drive the motor.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 6, an exhaust port 2 is opened on the left and right in the longitudinal direction of the lower main body 1, and a lid 4 having an intake port 3 on the upper surface forms a box. The lid 4 is detachably mounted on the right and left buckles 5, and a panel 9 having a switch 6, a lamp window 7, a sensor opening 8 and the like is arranged on the front surface. As shown in FIG. 1, a partition wall 11 having an intake port 10 opened therein is provided inside the box body, and a vortex chamber 12 communicating with the exhaust port 2 is formed on the left and right sides with the lower main body 1. A sirocco fan 13 is housed in the chamber 12, and is attached to a motor 16 fixed to a cylinder portion 15 connected by an arm portion 14 extending into the suction port 10 of the partition wall 11. Reference numeral 17 is a cover body of the motor 16. On the upstream side, a large number of receiving ribs 18 of the partition wall 11 are provided with a deodorizing filter 19 mainly composed of activated carbon, and a dust collecting filter 20 which is formed into a bellows shape and has a large effective dust collecting area. It is housed in the filter housing frame 21. FIG. 2 is a view taken in the direction of arrow A in FIG. 1, in which the buckle 5 is attached by inserting it from the outside into a frame 22 formed in the lid body 4, and an elastic engaging piece 23 is attached to a rib 24 of the lid body 4. Then, the urging spring 25 serves as a stopper. Reference numeral 26 denotes another end supporting piece of the biasing spring 25 formed on the lid body 4, which inserts and supports the guide rib 27 of the buckle 5 to further smoothly operate the buckle 5. Reference numeral 28 denotes an engaging piece formed on the buckle 5, which engages with an engaging hole 29 of the partition wall 11. A receiving rib 30 is formed on the partition wall 11 so as to face the engaging piece 28. As shown in FIGS. 3 and 5, a cover portion 31 is extended at the front portion of the filter housing frame 21 of the partition wall 11 to form a switch chamber 32 with the lower main body 1 so that the switch 6 and the like can be formed. At the same time, the board 34 on which the power switch 33 is arranged is housed. Reference numeral 35 is an actuator of the power switch 33, which is displaced by the projecting piece 37 of the lid 4 which is inserted through the slit 36 of the cover portion 31 to turn on / off the power.

The attaching / detaching operation of the lid body 4 in the above configuration will be described. When the lid body 4 having the buckle 5 is pushed down from above as shown in FIG. 4, the other end support piece 26 of the urging spring 25 receives the receiving rib 3 The urging spring 25 is compressed when the engaging piece 28 is inserted through the engaging hole 29, and the urging spring 25 attaches the engaging piece 28 to the partition wall 11 so that the cover body 4 Are fixed to the lower body 1 via the partition wall 11. At this time, the projection 37 of the lid 4 pushes the actuator 35 to close the power switch 33, and when the motor 16 is driven by the switch 6 or the like, the dirty air in the vehicle collects dust from the intake port 3. After passing through the filter 20 and the deodorizing filter 19, dust and odors are removed, and the clean air is guided from the suction port 10 to the vortex chamber 12 and is recycled from the exhaust port 2 into the vehicle. When the buckle 5 is pushed from the outside to disengage the engagement piece 28 from the engagement hole 29 and lifted, the lid body 4 can be removed and the power switch 33 is opened. The other end supporting piece 26 of the urging spring 25 formed on the lid body 4 is formed by sliding inward of the lid body 4 together with the frame 22 for the purpose of preventing sink marks that impair the appearance at the time of molding. Although it is difficult to obtain sufficient strength because the reinforcing rib that resists the biasing spring 25 cannot be formed due to the sliding distance B with the mouth 3, it is difficult to obtain sufficient strength. However, the receiving rib that faces the partition wall 11 is a lid made of a resin molded product. The strength of the other end support piece 26 of the biasing spring 25 can be easily provided at low cost without using a reinforcing member or the like for the buckle 5 mounting portion of the body 4, and deformation can be prevented.

Further, since the lower portion of the engaging piece 28 of the buckle 5 is set to be long, the lid body 4 placed on the main body is lifted up by D dimension as shown in FIGS. 4 and 5, and the lid body 4 is normally attached to the main body. It is possible to eliminate the inconvenience of driving the motor 16 by eliminating the problem that the protrusion 37 closes the power switch 33 in the state where it is not attached.
