JP-A-6-343587

  However, in the above conventional configuration, there is a problem that the number of parts increases because dedicated frame parts and lenses for attaching the LED substrate are required.

  In addition, since the vacuum cleaner is used while moving, and an electric blower is built inside, the lens exposed on the main body case hits something while moving and breaks from the gap between the opening and the lens. There were also problems such as exhaust leakage.

  Furthermore, since the LED substrate is assembled using a frame or the like on the back side of the main body case, workability is very poor.

  Accordingly, the present invention has been made to solve such problems, and provides a vacuum cleaner that can reduce the number of components, eliminate damage to the lens, exhaust leakage, and the like, and improve assembly workability. It is intended.

  In order to achieve the above object, the present invention relates to a vacuum cleaner including a display unit that performs display for prompting disposal of dust in a dust collection chamber or cleaning of a filter, and a light emitter constituting the display unit. The substrate is disposed in a main body case where a display portion of a light emitter is formed, and a thin portion that transmits light from the light emitter is formed in the main body case as the display portion. .

  Further, the substrate is fixed by two parts, a dust collection case constituting the dust collection chamber and a cover attached to a communication portion between the dust collection chamber and the electric blower chamber. is there.

  In addition, a holder for holding the light emitter by being mounted on the light emitter after fixing the substrate of the light emitter is provided.

  In addition, a translucent case cover that covers the main body case on which the display unit is formed is provided.

  According to the present invention, the light emitter and its substrate are arranged in the main body case where the display portion of the light emitter is formed, and the thin portion that transmits light from the light emitter is formed in the main body case as the display portion. Dedicated frame parts and lenses for mounting the board are not required, the number of parts can be reduced, lens damage, exhaust leakage, etc. can be eliminated, and assembly workability can be improved.

  Further, the light emitting substrate is fixed with two parts, a dust collecting case constituting the dust collecting chamber, and a cover attached to a communication portion between the dust collecting chamber and the electric blower chamber. Compared with the case of fixing with, the simplification of the mold structure of the corresponding part can be realized.

  In addition, since the holder of the light emitter is mounted after the substrate of the light emitter is fixed and holds the light emitter, the rib inside the case hits the light emitter when the main body case is attached, and the light emitter tilts. Can be prevented.

  Further, by providing a translucent case cover that covers the main body case on which the display portion is formed, it is possible to achieve differentiation in appearance.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an external appearance of a vacuum cleaner main body in an electric vacuum cleaner according to an embodiment of the present invention, FIG. 2 is a central longitudinal sectional view thereof, and FIG. 3 is a side view of the entire vacuum cleaner.

  The canister-type vacuum cleaner main body 1 includes a lower case 2 and an upper case 3, and a dust collection lid 4 that opens and closes an upper surface opening of a dust collection chamber, which will be described later, opened on the front upper surface of the upper case 3; It is formed from a front cover 9 having an insertion port 8 into which a hose 7 connected to an extension pipe 5 and a floor suction tool 6 is inserted.

  A caster-type small-diameter front wheel 10 is provided at the center of the front side of the bottom surface of the vacuum cleaner body 1, and a large-diameter rear wheel 11 is provided on the rear side of both side surfaces. Further, a handle 12 for carrying the cleaner main body is rotatably provided on the rear side of the dust collecting lid 4 on the upper surface side of the cleaner main body 1.

  In the vacuum cleaner main body 1, a dust collecting chamber 14 for both of which a dust collecting paper pack (not shown) and a cyclone type dust box 13 can be mounted is formed at the front, and an electric blower 15 at the rear. An electric blower chamber 16 in which is stored is formed.

  The dust collection chamber 14 is formed by a dust collection case 17 shown in FIG. 4A fixed to the front portion on the lower case 2 by a screw, and a suction port 17 a is formed at the frontmost portion of the dust collection case 17. ing. Further, an air inlet cover 18 shown in FIG. 4B is attached to an opening communicating with the dust collecting chamber 14 and the electric blower chamber 16, and a fine dust filter is held by the filter frame body in the lattice portion 18a. A filter fixture 19 is detachably mounted.

  When the dust collection case 17 and the air inlet cover 18 are mounted in the cleaner body 1, they are connected as shown in FIG. 5, and a rib 17 b and an air inlet cover 18 on the dust collection case 17 side are connected to the upper part on the rear side. The LED board attachment part 20 comprised by the side rib 18b is formed.

  As shown in FIG. 2 and FIG. 6 which is an enlarged cross-sectional view of an essential part of the LED board mounting portion 20, an LED board 22 on which an LED (light emitting diode) 21 as a light emitter is mounted is attached and fixed. It has become so. Further, as shown in FIG. 7, the LED 21 mounted on the attached substrate 22 is mounted with an LED folder 23 in which a funnel-shaped hole 23a is formed. The LED 21 is surrounded by the funnel-shaped hole 23a so that the LED 21 is inclined. It is configured to prevent.

  And the thin part which permeate | transmits the light from LED21 as the display part 24 is formed in the resin upper case 3 corresponding to the said LED position. Further, a translucent case cover 25 that covers the upper case 3 on which the display unit 24 is formed is provided. The translucent case cover 25 is configured to be colored with a color that is not complementary to the light emission color of the LED 21 because, for example, when the red LED is colored green, which is the complementary color of the red LED, the red light emission of the LED becomes invisible. Is essential. In FIG. 1, the display portion 24 formed of the thin portion is shown with hatching so that the display portion 24 can be seen.

  As described above, in the present embodiment, the LED substrate 22 is fixed to the other components 17 and 18 in the upper case 3 where the display unit 24 is formed, and the light from the LED 21 is transmitted to the upper case 3 as the display unit 24. As a thin part is formed, a dedicated frame part and lens for attaching the LED board 22 are not required, the number of parts is reduced, and the damage of the lens and exhaust leakage are eliminated, thereby improving the assembly workability. it can.

  Further, the LED substrate 22 is fixed with two parts, a dust collection case 17 constituting the dust collection chamber 14 and an air inlet cover 18 attached to a communication portion between the dust collection chamber 14 and the electric blower chamber 16. As a result, when fixing with any one of the dust collection case 17 and the air inlet cover 18, the LED board mounting portion has a complicated shape. Simplification can be realized.

  In addition, since the LED holder 23 that is mounted on the LED 21 and holds the LED 21 after the LED substrate 22 is fixed is provided, the rib 21 on the inner side of the upper case 3 hits the LED 21 when the upper case 3 is attached. Can be prevented.

  Further, by providing the translucent case cover 25 that covers the upper case 3 on which the display unit 24 is formed, the appearance can be differentiated.

  On the other hand, in this embodiment, as shown in FIGS. 8 to 11, lead wires 27 a and 27 b from the terminal portions 26 a and 26 b arranged in the hose insertion port 8 of the front cover 9 are connected to a main body rear main board (not shown). A part of the wiring process to be wired is routed through the outside of the front cover 9 and is hidden by the upper case 3 as shown in FIGS.

  Up to now, due to the miniaturization and slimming of the vacuum cleaner main body 1, the wiring processing space has been narrowed, and the mold strength has been difficult. That is, until now, wiring processing was performed in a narrow groove, and wiring processing was performed using a special spatula-like tool, and workability was poor.

  Therefore, in this embodiment, as shown in FIG. 8, only the lead wire 27b from the lower terminal portion 26b out of the terminal portions 26a and 26b arranged in the lateral direction of the hose insertion port 8 of the front cover 9 is provided. Wiring is processed through a groove on the lower inner side of the hose insertion port 8, and the lead wire 27 a from the upper terminal portion 26 a is processed through the outer upper portion of the front cover 9. Further, as shown in FIGS. 9 and 10, the outer wall of the dust collecting case 17 has a height substantially equal to the height at which the lead wires 27a and 27b passing through the outer side and the inner side of the front cover 9 are pulled out as described above. Further, a wiring processing rib 17c is formed.

  As described above, by performing a part of the lead wire processing in the front cover 9 through the outside of the front cover 9, sufficient wiring processing space and mold strength can be ensured. Thereby, the working efficiency can be improved. Further, it is possible to eliminate the space that has been secured in consideration of the strength of the mold for performing the conventional wiring process, and further miniaturization becomes possible. In addition, by providing the wiring processing ribs 17c at a height substantially equal to the height at which the lead wires 27a and 27b passing through the outer side and the inner side of the front cover 9 are drawn out, the workability of the wiring processing is improved.

  Moreover, in this embodiment, the deformation | transformation of the pipe retainer 30 for the stand accommodation which accommodates the vacuum cleaner main body 1 with which the hose 7 to which the floor suction tool 6 was connected via the extension pipe 5 was connected was stood up. It has a prevention mechanism.

  That is, the conventional pipe retainer has insufficient strength because the hook portion is supported only by the retaining ring portion, and the material is PP (polypropylene), so the stand is stored in a high temperature (40 ° C.) atmosphere. Then, deformation occurs. This problem is aggravated by the increase in weight due to the recent increase in pipe diameter and hose diameter. When deformation occurs, the pipe falls out and falls when the stand is stored.

  Therefore, in this embodiment, the rib 30c is formed inside the hook portion 30a of the pipe retainer 30 as shown in FIGS. 15 (b) and 16 (b), and FIGS. 15 (a) and 16 (a). As shown in FIGS. 15C and 15D, a substantially U-shaped rib 5c having a groove 5b into which the rib 30c is fitted is formed on the pipe 5a side of the extension pipe 5, as shown in FIG. As shown in FIG. 14, when the pipe retainer 30 is attached, the rib 30c is sandwiched between the ribs 5c from the pipe 5a to firmly support the hook portion 30a itself as shown in FIG.

  By configuring in this way, deformation in the horizontal direction of the hook portion 30a of the pipe retainer 30 is restricted to prevent deformation. Further, since the strength is high, the pipe retainer 30 can be downsized. The structure of the rib is reversed, that is, the same effect can be obtained even if the rib of the pipe is sandwiched between the ribs of the pipe retainer.

  In the present embodiment, as shown in FIGS. 17 and 18, in the handle that rotates about the rotation shaft 12 a, the upper case 3 is provided with a contact rib 3 a on the top surface (core side). A handle stopper is formed by applying a retaining rib 12b provided on the rotating shaft 12a.

  Conventionally, a handle that pivots around a pivot has been provided with a stopper only on the outside of the upper case. However, this stopper is not strong enough, and a stopper configuration space must be secured to increase the size of the stopper. Was needed.

  Therefore, in the present embodiment, a stopper 3b is provided on the outer side of the upper case 3 as shown in FIG. 19, and a contact rib 3a is provided on the top surface (core side) of the upper case 3, and a retaining rib 12b for the handle 12 is provided on this. The stopper is strengthened by hitting. This is configured so that it hits when the outer stopper 3b is deformed and works when an excessive force is applied, eliminating the need to increase the size of the outer stopper 3b. Securing is unnecessary. Moreover, since the outer stopper 3b may be small, the appearance is not impaired.

  Further, in the present embodiment, a device is provided for preventing the decorative plate 34 from being attached to the dust collection lid 4 shown in FIG. 1 for decoration as shown in FIG.

  Conventionally, in order to provide an undercut to prevent the tip of the decorative board formed to be narrow, a rectangular hole 34a is formed at the tip of the decorative board 34 as shown in FIG. The configuration is such that 34 a is fitted to the convex portion 4 a at the end of the dust collecting lid 4. However, with such a hole configuration, since walls are formed in all directions, a space corresponding to the wall thickness is required in at least the four directions, and the size cannot be reduced.

  Therefore, in this embodiment, as shown in FIGS. 21B to 21E, one of the four walls of the undercut portion is deleted, and the shape of the undercut portion is slanted with respect to the removal preventing direction. In this way, it prevents the omission. FIG. 21 (b) shows a state in which the lower wall 34b of the rectangular undercut portion (hole 34a) in FIG. 21 (a) is deleted, and the side wall 34c is peeled off by the arrow even if the lower wall is deleted. It becomes resistance to and can be prevented from coming off. FIG. 21 (c) is a side wall of the substantially parallelogram undercut portion (hole 34d) deleted. Even if the side wall is deleted, the lower wall 34e is peeled off by an arrow. It becomes resistance to the direction and can be prevented from coming off. FIG. 21 (d) shows the structure shown in FIG. 21 (c) arranged vertically symmetrically, and has a strong prevention structure in both directions. Further, FIG. 21 (e) is obtained by removing the wall on the short side inside the substantially trapezoidal undercut portion (hole 34f), and can correspond to all directions. By configuring as described above, the size can be reduced.

  In addition, in the case where the dust collection lid 4 to which the decorative plate 34 is attached as described above is formed of a transparent resin, when a rib or the like is formed on the back surface side of the dust collection lid 4 formed of a transparent resin, it can be seen from the front side. Since the appearance is deteriorated, an opaque backing plate is provided on the back side of the transparent dust collecting lid 4, and ribs or the like are formed on the backing plate. In the nail configuration for stopping the decorative plate 34 and the dust collecting lid 4 in such a structure, in this embodiment, the nail of the decorative plate 4 is prevented from being removed by a rib formed on the backing plate.

  Up to now, the claw configuration for stopping the decorative plate and the dust collecting lid as described above is a drop in the state where the decorative plate 34 is assembled to the dust collecting lid 4 provided with the backing plate 35 as shown in FIG. In order to prevent the decorative plate 34 from coming off due to such an impact, the allowance for the claw 34g of the decorative plate 34 is increased, or the deflection of the claw 34g is increased. However, in order to strengthen the nail configuration, it is difficult to assemble if it takes a large allowance for the nail 34g or increases the bending of the nail 34g. Further, in order to prevent sink marks at the time of molding the decorative plate 34, it is effective to form the nail 34g thin. However, if the nail 34g is formed thin, the nail 34g is easily erased.

  Therefore, in the present embodiment, as shown in FIG. 22B, a rib 35a for preventing the claw 34g of the decorative plate 34 from coming off is formed on the backing plate 35. First, the decorative plate 34 and the dust collecting lid 4 are assembled first. (The nail 34g has a small allowance and deflection, and may be formed thin to prevent sink marks). Next, when the backing plate 35 is assembled, the ribs 35a provided on the backing plate 35 come into contact with the opposite side of the aforementioned claw 34g, so that the claw 34g is sandwiched from both sides, thus preventing the removal. Can be done effectively.

  By constructing as described above, it is easy to assemble and difficult to come off, and the effect of preventing the nail 34g from being erased can be obtained.

  The decorative plate 34 and the backing plate 35 are preferably screwed, and the dust collecting lid 4 is preferably sandwiched and fixed between the decorative plate 34 and the backing plate 35.

  Until now, as shown in FIGS. 23A and 23B, the decorative plate 34 and the dust collecting lid 4 are stopped by the claw 34g, and the dust collecting lid 4 and the backing plate 35 are stopped by the claw 35b or the screw 35c. It was configured to be stopped by adjacent parts.

  However, if it is configured to be stopped by adjacent parts, the number of portions to be stopped by the claws 34g, 35b or the screw 35c increases. When the external part such as the dust collecting lid 4 is a transparent part, it can be stopped only at a limited position of the decorative board (opaque part) 34. Therefore, if the number of parts to be stopped increases, the size cannot be reduced. Moreover, since it is the triple structure of the decorative board 34, the dust collecting cover 4, and the backing plate 35, it becomes thick.

  Therefore, in the present embodiment, as shown in FIGS. 23C and 23D, a screw boss 34h is provided from the decorative plate 34, and the dust collecting lid 4 is sandwiched between the backing plate 35 and the backing plate 35 and the screw 35c. Try to stop. The triple part is tightened together. As shown in FIG. 23 (d), the screwing portion may have a double structure on one side. FIG. 24 is a side sectional view showing the embodiment.

  By configuring as described above, it is possible to reduce the number of places to be stopped by co-fastening, and it is also possible to form a double component part, so that there is room for space, leading to miniaturization and weight reduction.

  On the other hand, in this embodiment, a rib (described later) of a fixing component for simple storage of the gap suction tool (in this embodiment, a hose retainer 41 for attaching the gap suction tool 40 to the hose 7 shown in FIGS. 3 and 25). The gap suction tool 40 is positioned by fitting into the gap of the pipe fitting rib 40a.

  Conventionally, the shape of the suction tool for the gap of the vacuum cleaner is based on a cylindrical shape, and the configuration for fixing the suction tool for the gap by sandwiching the circumference is often used. Due to variations in the molding of the parts, the fixing force is not stable, and the suction tool for gaps has fallen and it has become difficult to attach and detach.

  Therefore, in the present embodiment, as shown in FIG. 26 (a), the hose 7 is sandwiched around the circumference of the hose 7 and fixed to the bellows-like hose 7 by the rib 41a. In the configuration in which the circumference is sandwiched and detachably attached, the rib 41b provided on the hose retainer 41 is fitted between the pipe fitting rib 40a of the gap suction tool 40 as shown in FIGS. 26 (a) and 26 (b). It is comprised so that it may do. The figure which looked at this hose retainer 41 from each direction is shown in FIG. The gap suction tool 40 has a small-diameter portion 40b and a large-diameter portion 40c so that they can be connected to hoses or extension pipes having different inner diameters. In order to prevent the occurrence, a large number of ring-shaped pipe fitting ribs 40a are formed.

  As described above, the rib 41b provided on the hose retainer 41 is fitted between the pipe fitting ribs 40a of the gap suction tool 40, thereby serving to position the gap suction tool 40 in the vertical direction. It has a stable holding force and is easy to use and can handle variations in the molding of parts even if the suction tool 40 for gaps does not fall off during cleaning or is not easily controlled. A hose retainer 41 can be provided.

  On the other hand, in the present embodiment, the click structure for obtaining a click feeling when the dust collecting lid 4 is opened has a bending rib described later, and the bending rib is installed in the upper case 3.

  In the past, the rib for bending was formed on the dust collection lid, but the dust collection lid is spatially limited, and the rib dedicated to the rotating shaft may function as a click deflection. It is necessary to give the dynamic shaft strength, and there is a problem that durability performance is lowered by bending each time the click is performed.

  Therefore, in this embodiment, as shown in FIGS. 28 and 29, the backing plate 35 of the dust collecting lid 4 is formed with a click portion 35d having rigidity that does not flex, and the upper case 3 has a long and flexible click. The bending rib 3d is formed. In the process of opening the dust collecting lid 4, as shown in FIGS. 30 and 31, the click part 35 d on the backing plate 35 side of the dust collecting lid 4 pushes and spreads the click bending rib 3 d on the upper case 3 side. 32 and 33, when the dust collecting lid 4 is fully opened, the click part 35d of the backing plate 35 of the dust collecting lid 4 rides on the click bending rib 3d on the upper case 3 side and clicks. Completed.

  By configuring as described above, since the long and flexible click bending rib 3d can be formed on the upper case 3 side, the strength of the rotating shaft formed on the dust collecting lid 4 side is maintained, A good and high-quality click function (feel) can be realized.

  Further, in the present embodiment, the upper case 3 and the case cover 25 have a mechanism that serves as a guide and a blindfold for the rear end portion of the dust collection lid 4 that draws an arc by rotation of the dust collection lid 4. It is what.

  Conventionally, it has been necessary to provide a large clearance at the rear end portion of the dust collection lid that draws an arc by rotation of the dust collection lid in order to avoid interference with other parts. In this case, the problem that a clearance gaps the external appearance arises. Further, there is a case where interference occurs during rotation due to deformation during molding of the dust collecting lid. For this reason, hitherto, a pad is provided from other parts on the lower side of the rear end portion of the dust collecting lid which is deformed to restrict deformation. Today, transparent parts are often used for appearance parts, so that the application of this deformation regulation may also damage the appearance.

  Therefore, in this embodiment, the upper case 3 and its case cover 25 are formed in an offset shape at the rear end of the dust collecting lid 4. At this time, the upper case 3 and its case cover 25 overlap the rear end portion of the dust collection lid 4 at the rear end portion of the dust collection lid 4 (see FIG. 2), and viewed from above as shown in FIG. Since the upper case 3 and the case cover 25 exist under the gap S formed between the rear end portion 4b of the dust collecting lid 4 and the upper case 3 and the case cover 25, The gap S becomes inconspicuous.

  That is, as shown in FIG. 35, the upper case 3 and its case cover 25 side are formed in a shape inclined in an arc shape along a turning locus indicated by a broken line of the rear end portion 4b of the dust collecting lid 4. The rear end portion 4b of the dust collection lid 4 (and its backing plate 35) is formed in an inclined shape in accordance with the inclined shape. In other words, the rear end portion 4b of the dust collecting lid 4 is configured to cover the upper case 3 and the inclined surface on the case cover 25 side. Although the rear end portion 4b of the dust collection lid 4 (and its backing plate 35) is not inclined as described above, a certain effect can be obtained. However, since the gap on the upper surface side becomes large, as described above. It is preferable to adopt a configuration that is inclined in a shape along each other.

  By configuring as described above, the upper case 3 and the case cover 25 serve as a blindfold for the gap S, and serve as a guide for deformation regulation and rotation.

  Further, in the present embodiment, the dust collection case 17 is provided, and an exhaust leak prevention rib described later is formed in the dust collection case 17, and the exhaust leak prevention rib also serves as a wiring process.

  As described above, in the configuration in which the dust collecting case 17 is mounted on the lower case 2 and the front side thereof is covered with the front cover 9, it is necessary to take measures against waste leakage from the front side. Until now, as shown in FIG. In addition, an exhaust leakage prevention rib 17 d is formed in the dust collecting case 17, and a wiring processing groove 2 d is formed in the lower case 2. However, in this case, the exhaust leakage preventing rib 17d and the wiring processing groove 2d formed in the dust collecting case 17 are formed in separate parts, and the structure becomes complicated.

  Therefore, in the present embodiment, as shown in FIGS. 37 and 38, the dust collection case 17 is formed with the exhaust leak prevention rib 17d for preventing the exhaust leak indicated by the arrow, and the wiring 47 is connected to the exhaust leak prevention rib 17d. A groove 17e is formed so as to serve as a wiring processing groove.

  With this configuration, it is possible to obtain the effects of both exhaust leakage prevention and wiring processing with a single rib, and the structure is simplified.

  Moreover, in this embodiment, it has an undercut structure for restricting the opening of the joint part of the upper case 3 and the lower case 2.

  When the front cover 9 is screwed from the front side to reduce the size and slimness of the vacuum cleaner body 1, the upper and lower openings of the upper case 3 and lower case 2 are completely opened due to the screwing characteristics. Cannot be regulated.

  Therefore, in the present embodiment, as shown in FIG. 39, the front cover 9 and the upper case 3 are provided with an undercut configuration so that the step 9c formed in the front cover 9 has a claw portion formed in the upper case 3. 3c is hooked to regulate the opening of the mating part up and down. It is to be noted that the same effect can be obtained by providing an undercut configuration in the dust collection case 17 fixed on the lower case 2 with screws and the upper case 3. Thereby, even when the front cover 9 is screwed from the front surface with the screw hole 3e, the appearance can be easily adjusted.
