Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to an on-vehicle vacuum cleaner for cleaning dust inside an automobile, and particularly relates to a vacuum cleaner for an automobile for cleaning dust inside an automobile. Regarding the lid body.

(Prior Art) Conventionally, although not a vacuum cleaner for an automobile, as described in Japanese Utility Model Application Publication No. 60-97560, or as shown in FIGS. 13 and 14, a vacuum cleaner body A suction port 3 to which a hose is removably inserted and connected is provided on a first lid body 2 that freely opens and closes the dust collection chamber that opens upward in the interior of the lid 1, and this suction port 3 is closed so that it can be opened and closed from the outside. A household vacuum cleaner is known in which a shutter 4, which is a second lid body, is slidably supported. In this type of conventional vacuum cleaner, an opening 5 is formed on the outer upper surface of the first lid body 2 to face the suction port 3, and a guide plate is provided on the side of the suction port 3. A structure was adopted in which the shutter 4 was slidably supported between the shutter 4 and the shutter 6. Note that a knob 7 protrudingly formed at the end of the shutter 4 protrudes outward from the opening 5.

However, in this conventional structure, even when the shutter 4 is closed, a recess with a depth t is formed in the opening 5.
The design was not good in terms of appearance.

This is a serious drawback, especially when the vacuum cleaner is installed in a car where interior design is a consideration, and the product quality is significantly impaired.

In addition, dust inside the car, such as dirt kicked up from a mat inside the car, tends to accumulate in the recess.

Furthermore, although the structure is such that the opened shutter 4 is housed inside the first lid body 2, in order to open the shutter 4, a portion of the shutter 4 with a length corresponding to the width W of the opening 5 is opened. Since a storage space is required within the first lid 2, the shape of the first lid 2 becomes large. However,
In particular, automobile vacuum cleaners are required to be small and compact because they are installed in the narrow interior of a car. Therefore, in the automobile vacuum cleaner, the increase in size due to housing the shutter 4 within the first lid body 2 becomes a major drawback.

Furthermore, in the past, the shutter 4 was constructed without any particular locking means for locking it in the closed position, but for this reason, if the vacuum cleaner was installed inside a car, it would not be possible to lock the shutter 4 in the closed position. There is a risk that the shutter 4 may open due to vibration or the like, and dust may leak from the dust collection chamber of the cleaner body 1.

By the way, conventionally, for cleaning the inside of a car, a hand-held vacuum cleaner, which has a handle on the upper rear part of a small vacuum cleaner body having a suction port at the front end, has often been used.

This type of hand-held vacuum cleaner has a structure in which a switch for turning on and off the electric blower inside the vacuum cleaner body is provided on the front part of the handle. on the other hand,
In the household vacuum cleaner as described above, a switch is provided in the grip tube of the hose, but in any case, conventionally, the switch was always exposed.

As a result, the design is not good, and there is a risk that the electric blower may be started even though it is not necessary due to a child's mischief.

(Problems to be Solved by the Invention) As described above, in conventional vacuum cleaners, even when the suction port is closed by the shutter, which is the second lid, a recess is formed above the suction port, resulting in poor design. Additionally, there is a problem in that dust tends to accumulate in the recess. Further, since the shutter is housed in the first lid on the side of the vacuum cleaner body, there is a problem of increasing the size of the vacuum cleaner. Furthermore, since the shutter is not locked in the closed position, there is a problem that the shutter tends to open spontaneously due to impact or the like.

In addition, in conventional vacuum cleaners, the switch that turns the electric blower on and off is always exposed, which not only has a poor design, but also makes it easy for the switch to be manipulated even when it is not needed.

The present invention aims to solve these problems, and aims to provide a vacuum cleaner for automobiles that has a good design, is less likely to collect dust on the lid portion where the suction port is closed, and can be made compact. This is the first objective.

In addition, the second purpose of this automotive vacuum cleaner is to further enhance the design, improve usability, and prevent the switch that turns the electric blower on and off from being manipulated by mischief. It is.

Furthermore, the lid that closes the suction port can be reliably locked in the closed position, and the lid will not open due to vibrations when the car is running, and the lid can be locked in the closed position. The third purpose is to make it possible to reliably recognize I11.

[Structure of the invention]

(Means for Solving the Problems) The automobile vacuum cleaner according to claim 1 of the present invention is provided with an electric blower and a dust collection chamber communicating with the electric blower inside, and a suction port communicating with the dust collection chamber. This vacuum cleaner includes a vacuum cleaner body provided on the outer surface and a lid body that freely opens and closes the suction port of the vacuum cleaner body. In order to achieve the first object, the suction port is provided at the bottom of a recess formed by recessing inward from the outer surface of the vacuum cleaner main body, and the suction port is provided adjacent to the recess in the vacuum cleaner main body. A closed position of the lid is defined as a position that continues on the outer surface and covers the recess, and an open position is defined as a position that rests on the outside of the outer surface adjacent to the recess in the vacuum cleaner main body.

For this purpose, the lid has side portions on both sides that protrude into the recess, one side inside the recess of the vacuum cleaner body and one side of the lid opposite this side. A linear guide portion is provided on one of the two side surfaces, the other side surface portion within the recess, and one of the other side surface portion of the lid body opposite to this side surface portion, and the other side is provided with a linear guide portion on each of the linear guide portions. A dot-like engagement portion is provided, and the linear guide portion extends from one end where the dot-like engagement portion is located to the vacuum cleaner near the recess when the lid body is in the closed position. an inclined part extending in a direction oblique to the outer surface of the main body; and a parallel part forming an obtuse angle with the inclined part and extending from the other end of the inclined part in a direction parallel to the outer surface of the vacuum cleaner main body in the vicinity of the recessed part. In addition, the inclined portion has a length in the vicinity of the recess in a direction perpendicular to the outer surface of the vacuum cleaner body that is longer than the thickness of the lid in the same direction, and the entire linear guide portion is , the length of the parallel portion in the extending direction is longer than the distance in this direction from the end of the recess to the position opposite to the suction port.

In addition, in order to achieve the second object, the automotive vacuum cleaner according to claim 2 further includes a switch for turning on and off a power supply circuit to the electric blower, and a switch for controlling the amount of dust stored in the dust collection chamber. There is a dust meter that detects and displays dust and a suction port on the vacuum cleaner body [! ! It is installed inside the IN.

Furthermore, in order to achieve the third object, a clamp claw part is provided at one end in the sliding direction of the lid body, and a clamp claw part is provided in the corresponding recess part of the vacuum cleaner body. A locking hole is provided at the position where the clamp claw portion is removably engaged to lock the lid in the closed position. a normally closed opening/closing means for turning on and off a power supply circuit to the lamp, provided outside the recessed portion and adjacent to the locking hole; is provided in a position where the opening/closing means is pressed and turned off by the clamp claw portion of the lid body engaged with the locking hole,
Furthermore, the lid is provided with a light-transmitting portion at a position facing the lamp when the lid is in the closed position.

(Function) In the automobile vacuum cleaner according to claim 1 of the present invention, when not in use, the lid covers the recessed part recessed inward from the outer surface of the vacuum cleaner body, and closes the suction port at the bottom of the recessed part. This prevents dust from leaking from the dust collection chamber in the vacuum cleaner body through this suction port, and in this state, the lid is continuous with the outer surface of the vacuum cleaner body adjacent to the recess. Furthermore, when cleaning, the lid is opened to open the suction port, but to open the lid, the lid is slid in one direction. At this time, along the linear guide portion provided on one side of the recess and one side of the lid, and on the other side of the recess and the other side of the lid. , the dotted engagement portions provided on the other side slide.

The dot-like guide part first slides on the sloped part on one end side of the linear guide part, and this slope part extends from the one end where the dot-like engagement part is located to the recessed part when the lid body is in the closed position. Since it extends in a direction inclined with respect to the outer surface of the vacuum cleaner main body in the vicinity, as the dotted engagement portion slides on the inclined portion, the lid body separates from the outer surface of the vacuum cleaner main body. Moreover, since the length of the inclined part in the direction perpendicular to the outer surface of the vacuum cleaner body near the concave part is longer than the thickness of the lid body in the same direction, the lid body is
It is separated from the outer surface of the vacuum cleaner body by more than that thickness.

Next, the dot-shaped engagement part moves from the inclined part to the parallel part of the linear guide part, but at this time, the dot-like retention part moves smoothly because the inclined part and the parallel part form an obtuse angle. . Since the parallel portion extends in a direction parallel to the outer surface of the vacuum cleaner body near the concave portion, as the dotted engagement portion slides on the inclined portion, the lid body extends toward the outer surface of the vacuum cleaner body. move parallel to
It opens by resting on the outside of the outer surface of the vacuum cleaner body adjacent to the recess. Moreover, since the length of the entire linear guide in the direction in which the parallel part extends is longer than the distance from the end of the recess to the position on the opposite side of the suction port in this direction, the length of the entire linear guide will be released.

During cleaning, by driving an electric blower, for example, dust sucked in from a hose connected to the suction port is guided to the dust collection chamber and captured. After cleaning, the lid is slid in the opposite direction to close it, but at this time as well, the lid is guided by the dotted engagement portion and the linear guide portion so that the lid rests on the outer surface of the vacuum cleaner body. It is guided continuously from the position where it rests on this outer surface to the position where it covers the recess.

In addition, in the automotive vacuum cleaner according to claim 2, since the switch and the dust meter are located in the recessed part of the vacuum cleaner body where the suction port is located, when the lid is closed, the switch and the dust meter are disposed in the vacuum cleaner body. The meter is covered. Therefore, it is possible to prevent the switch from being operated unnecessarily due to a child's mischief or the like. When the lid is opened during cleaning, the switch and dust meter are exposed.
By operating the switch, the user turns on and off the power supply circuit to the electric blower to drive or stop the electric blower. Further, the dust meter detects and displays the amount of dust accumulated in the dust collection chamber, and the user knows whether or not it is necessary to empty the dust by looking at the dust meter.

Furthermore, in the automobile vacuum cleaner according to claim 3, when the lid is closed, the clamp claw portion of the lid is engaged with the locking hole in the recess of the vacuum cleaner body, and the lid is in the closed position. When locked, the lid will not open accidentally even if it is subjected to vibrations when the car is running. Furthermore, when the lid is closed, the normally open opening/closing means is pressed and turned off by the clamp claw that is engaged with the locking hole, and the power circuit to the lamp in the recess of the vacuum cleaner body is turned off. , the lamp goes out. On the other hand, when cleaning, the clamping claw is removed from the locking hole and the lid is opened, but as the clamping claw is separated from the normally open opening/closing means, this opening/closing means is turned on. The lamp lights up and the area around the suction port is illuminated. Also, after cleaning, close the lid again, but if the clamp claw is not securely engaged with the locking hole, the lamp will remain lit. By seeing the light leaking from the transparent part, the user can reliably know that the clamping claw part is not reliably engaged.

As the protrusions 83, 83, 84, 84 slide on the 1.91.92.92, the second lid 81 slides over the first lid 1.
move forward in parallel with the upper outer surface 55 of 3.

Finally, the second lid 81 is connected to the first lid 13.
It opens by resting on the upper outer surface 55 of the front part.

Moreover, due to the entire length L2 of the guide groove 87.87.811.118, the suction port 5
7 is fully open.

Note that when the second lid body 81 is opened, the side surface portion 82° 82 closes the gap 5 between the first lid body 13 and the handle 46.
Enter 4°54.

By the way, FIG. 2 shows the position of the rear projection 83 within the rear guide groove 87. In the figure, 831 is the position of the protrusion 83 when the second lid 81 is closed, and 83b is the position of the protrusion 83 when the second lid 81 is floating and its front end is at the stepped portion 58 of the first lid 13. The position of the protrusion 83 immediately after passing over the
83c is the position of the protrusion 83 when the second lid 81 is passing over the front part of the first lid 13, and 83d is the position of the protrusion 83 when the second lid 81 is fully opened. It's the location. The same holds true for the relationship between the front guide portion 88 and the front protrusion 84.

In this way, when the second lid 81 that opens and closes the suction port 57 is opened, it is moved outside the first lid 13 of the vacuum cleaner body 11 instead of being stored inside the vacuum cleaner body as in the conventional case. With this structure, there is no need for a storage space for the second lid 81 in the vacuum cleaner body 11, and the vacuum cleaner body 11 can be particularly downsized.

Note that when the second lid body 81 starts to open, the clamp claw portion 9 of the second lid body 81 as shown in FIG.
8 elastically disengages from the locking portion 100 of the locking hole 99 of the first lid body 13 and exits forward from the locking hole 99. At the same time, the clamp claw portion 98 separates from the movable contact piece 102 of the opening/closing means 77, so that the movable contact piece 102 comes into contact with the fixed contact piece 1fll, and the opening/closing means 77 is turned on. As a result, the connector 34 and the conductor 105 are connected from the vehicle battery.
, 106, 107 and the contact piece 101°1G2, power is supplied to the lamp 76, and this lamp 7 is energized.

Therefore, when not in use, the unevenness of the knob of the switch 66 and the unevenness of the display window 68 of the dust meter 67 do not appear on the outside, so that the appearance design when not in use is further improved. At the same time, since the power switch 66 is hidden, it can be prevented by children's mischief.
It is safe because the switch 66 is not accidentally turned on even though it is not necessary.

Moreover, since the second lid body 81 is securely locked in the closed position by the engagement between the clamp claw part 98 and the locking part 100, the second lid body 81 can be securely locked in the closed position even if it is subjected to vibrations caused by the running of the automobile. My body 81 doesn't open up. Therefore, safety is further improved and there is no problem with marketability.

By the way, even if the user intends to close the second lid 81 by sliding it backward, the locking hole 99 of the
If the clamp claw part 98 of the second lid body 81 is not securely engaged, the movable contact piece 102 will remain in contact with the fixed contact piece 101, so the lamp 76 will not go out and will remain lit. . Since the light from this lamp 76 leaks outward from the transparent portion 10g at the rear of the second lid 81, the user sees this light and confirms that the second lid 81 is not locked. It is sufficient to easily know that the second lid 81 is not closed securely. In this way, it is possible to know with certainty whether or not the second lid body 8I is completely closed.
This second lid 81 can be reliably closed. Second
The same thing happens when you forget to close the lid 81 of the lamp 76, but in this case, the lamp 76 is
