Description

[Detailed description of the invention] Industrial application field The present invention includes a main case with an upwardly open dust collection chamber, a dust lid that covers the dust collection chamber from above, and a dust collection bag in the dust collection chamber. This invention relates to a vacuum cleaner in which a vacuum cleaner is installed.

BACKGROUND ART Conventionally, in a vacuum cleaner having a dust lid 2 covering an upwardly open dust collection chamber 1 as shown in FIG. 4, an indicator 3 indicating the amount of collected dust is used.
is housed in the indicator housing section 4 and is disposed protruding from the back surface of the dust lid 2.

Then, as shown in FIG. 5, the dust cover 2
A rib 5 is provided near the indicator storage part 4 protruding from the back side of the dust collection chamber 1 to prevent the dust collection bag 7 installed in the dust collection chamber 1 from coming into close contact with the inner surface of the dust lid 2 and to prevent the dust collection bag from being torn. ing.

Furthermore, a nameplate 6 is attached to the top surface of the dust lid 2 with an adhesive such as double-sided tape to cover the area other than the display part of the indicator 3.

Problems to be Solved by the Invention However, in the case where the rib 5 is provided adjacent to the indicator storage section 4 as described above, the dust collection bag 7 installed in the dust collection chamber 1 is Since it spreads out in contact with the tip surface of the rib 5, when dust accumulates, there is no passage for the passing air from the outer surface of the dust collection bag 7 in front of the rib 5 to pass through, and the suction force of the vacuum cleaner ( suction air volume)
There were cases where the value decreased.

Further, the gate during molding is normally provided on the cabinet side (on the surface of the dust lid 2), but it is provided in the indicator storage section 4 because it is necessary to hide the gate marks. However, as mentioned above, by providing the rib 5 adjacent to the indicator housing 4, the resin injected during molding first flows to the rib 5 and then flows to the surface, so that the resin flowing to the rib 5 is By being cooled first, the resin on the surface that flows later is affected by sink marks, welds, etc., which deteriorates the product quality.

Furthermore, the inside of the dust collection chamber 1 is in a negative pressure state due to dust suction, but when the suction port is sealed during cleaning, the inside of the dust collection chamber 1 becomes even more negative pressure, and the dust lid 2 bends in the direction of arrow B. state. If this is done repeatedly, the nameplate 6 attached to the top surface of the dust cover 2 may receive distortion due to bending and come off from the adhesive surface. There was a problem that the storage section 4 became large.

The present invention solves these conventional problems and provides a vacuum cleaner with good performance and high marketability.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to protrude from the back side of the dust cover to store an indicator that indicates the amount of collected dust. At the same time, above the dust collection chamber, a rib forming a ventilation path from the dust collection chamber to the indicator is integrally suspended from the back surface of the dust lid, and an end of the rib on the indicator housing side and the indicator are provided. A space is provided between the outer walls of the storage section.

Function The technical means of the present invention works by providing a space between the edge of the rib and the outer wall of the indicator housing, which prevents the dust lid from coming into close contact with the dust bag. Even if the dust collection bag expands and comes into close contact with the rib tip and indicator storage area, the area formed by the aforementioned rib and indicator storage area is
Since the space between the two is not blocked, no matter how much the dust collection bag expands, a ventilation path can be secured between the dust collection bag and the dust lid, which prevents performance deterioration due to a decrease in air volume.

In addition, when providing a gate for resin molding in the indicator storage section, the long ribs adjacent to the gate are eliminated, so the resin injected during molding first flows into the ribs to prevent adhesion, and then onto the surface. This can prevent molding defects such as welds and sink marks on the surface portion due to rapid cooling of the rib portion.

Furthermore, by making the indicator storage part independent so that it does not come into contact with the adhesion prevention rib,
When the vacuum cleaner is running, the suction port is sealed and the dust collection chamber is under negative pressure, and even if the dust cover bends toward the dust collection chamber due to the negative pressure, the indicator storage section will bend independently, so the indicator storage section cannot be moved upward. No deflection force is transmitted to the nameplate that is pasted so as to cover the nameplate more closely, so it does not come off the adhesive surface and can be adhered with a minimum amount of adhesive.

Embodiments Hereinafter, embodiments will be described based on the drawings.

In FIGS. 1 to 3, reference numeral 8 denotes a main case having an upwardly open dust collection chamber 9 on the front side.

In the dust collecting chamber 9, a dust collecting bag 10 for collecting dust is positioned by an intake hole packing 11, and the upper part of the mouth frame 12 is held and fixed by a holder 13.

A rotatable dust lid 14 is attached to the upper opening.

The dust lid 14 is also provided with an indicator 15 for indicating the amount of dust collected in the dust collection bag 10 and for preventing a temperature rise when the bag is sealed, thereby communicating the inside of the dust collection chamber 9 with the outside. ing.

At the front of the main case 8, there is a front cover 16 having a connection part for connecting the main body and a hose.
is attached to fix the intake hole gasket 11. An upper body 17 is attached to the rear upper surface so as to cover the main case 8.

Reference numerals 18 and 19 are front wheels and rear wheels for movement disposed at the bottom of the main case 8.

Next, the configuration of each part of the dust lid 14 and the indicator 15 will be explained.

Reference numeral 20 denotes an indicator storage section for storing the indicator 15 in the dust lid 14, and projects from the back surface of the dust lid 14.

In addition, a dust collection bag 10 is provided on the inner surface of the dust lid 14.
A rib 21 for preventing the inner surface of the dust lid 14 from coming into close contact with the inner surface of the dust lid 14 is provided adjacent to the indicator storage section 20, and the rib 21 and the indicator storage section 2
0, two gaps D are formed between the two.

Further, the indicator 15 is communicated with the inside of the dust collection chamber 9 via an indicator elbow 22, and the indicator shim 23 is pulled in the direction of arrow E every time the negative pressure inside the dust collection chamber 9 increases. . In addition, the indicator 15 is
The name plate 24 is arranged so that the back surface of the name plate 24 is in contact with the indicator 15 in order to press it from above.

Next, the functions of the dust lid 14 and the indicator will be explained.

As shown in FIG.
0 and the rib 21 that prevents the dust collection bag 10 from coming into close contact with each other.
Even if dust is collected inside and spreads into the dust collection chamber 9 and comes into close contact with the indicator storage part 20 and the rib 21,
Since there is a gap D, the gap D can be secured as a ventilation path for the wind flow in the direction perpendicular to the plane of the paper in the figure. Even if it spreads into room 9, the wind is always
Due to the increased flow, there is no decrease in air volume, and therefore, cleaning can be performed indefinitely without reducing suction power.

In addition, as shown in FIG. 2, when molding the dust lid 14, the cage 25 is located on the cabinet side, so in consideration of the product appearance and resin flowability, the cage 25 is placed near the indicator housing section 20 approximately in the center of the dust lid 14. However, in this case, if there are ribs running vertically and horizontally near the gate, the resin will flow to the ribs first and begin cooling, and then flow to the flat area, resulting in welds and Sink marks appear on the exterior, but as shown in this example,
By separating one end of the rib 21 in the vicinity of the gate 25 (indicator storage section 20), resin can be prevented from flowing into the rib 21, and weld defects during molding as described above can be prevented.

Further, as shown in FIG. 3, when the vacuum cleaner is put into operation and the end of the hose is sealed and opened, the negative pressure inside the dust collection chamber increases and the hose flexes in the direction of arrow F. However, as mentioned above, since the indicator storage part 20 and the rib 21 are separated, even if the dust cover 14 is bent due to negative pressure, the part 26 surrounded by the dashed line will not be distorted as a whole, so the indicator can be removed. The nameplate 24 attached to the upper surface of the storage section 20 is not subjected to excessive bending or twisting. Therefore, the adhesive portion of the name plate 24 will not shift or float due to the bending of the main body.

Effects of the invention As described above, the present invention has an indicator storage section that is provided protruding from the back of the dust lid inside the dust collection chamber, and an indicator storage section that is made of ribs that are installed adjacent to the indicator storage section that prevents the dust lid from coming into close contact with the dust collection bag. By providing a space between the dust collection bag and the end of the dust collection chamber, even if the dust collection bag expands inside the dust collection chamber, the air can be ensured to flow into the dust collection chamber. However, the performance does not deteriorate due to a decrease in air volume.

In addition, since the indicator storage part is independent from the ribs arranged on the back of the dust cover, even if the tip pipe is repeatedly sealed and opened during operation, the entire indicator storage part deforms at the same time. The nameplate affixed to the top surface of the dust cover will not shift or come off due to twisting or bending of the dust cover, allowing the product to remain in good condition for a long time.
