Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a vacuum cleaner that is provided with a storage section for storing a gap nozzle and a shelf nozzle in the upper part of a main case having a motor chamber.

Prior Art Conventionally, for example, in the vacuum cleaner shown in Fig. 4, replacement nozzles (shelf nozzle 1, gap nozzle 2)
The storage lid 3 that covers the storage lid 3 has its front fixing claw 4 engaged with the upper body 5, and the ribs 6 on both sides of the storage lid 3 are brought into contact with the upper body 5 and held and fixed. The hanging part 7 was pulled upward to disengage the fixing claw 4 and rotated in the direction of arrow A.

Problems to be Solved by the Invention However, with such a structure, when the storage lid 3 is closed, there is a space between the storage part that houses the replacement nozzle and the storage lid 3, so the storage lid cannot be closed. 3 from the top surface with your finger, or remove the storage lid 3.
There was a problem in that the storage lid 3 would crack or become white when something was dropped onto it.

In addition, since the storage lid hook 7 is pushed down in the direction of arrow C no matter where the storage lid hook 7 is pressed during the length B on the storage lid 3, the fixed claw 4 has a holding mechanism that repeats opening and closing each time it is pressed. If you install the vacuum cleaner, the locking claw will open due to the shock of the storage lid 3 hitting your body while you are carrying the vacuum cleaner.
It was not possible to have a repetitive holding configuration as described above.

Furthermore, in order to prevent the central part of the storage lid 3 from bending or whitening, some types have ribs or boss-shaped protrusions on the back surface of the storage lid 3, but this prevents sink marks from occurring on the outer surface of the storage lid 3 due to the ribs or bosses. , the product's marketability was impaired.

The present invention solves these conventional problems by reducing the deflection of the central part of the storage lid.
The purpose is also to improve the strength against whitening cracks.

Means for Solving the Problems In order to achieve the above object, the technical means of the present invention is such that the partition wall that separates the shelf nozzle and the gap nozzle of the storage section in which the replacement nozzle is stored is brought into contact with the back surface of the storage lid. It is placed in a certain position.

Effect The effect of this technical means is that the storage lid is held on the upper body by the front fixing part, and the fixing part repeats opening and fixing every time the upper part of the fixing part is pushed from the top surface of the storage lid. By bringing the convex partition wall that separates the replacement nozzles configured on the upper body into contact with the back surface of the storage lid, the storage lid will not bend downward even if you press the center part of the storage lid surface with your finger. No whitening or cracking occurs.

Further, since the storage lid is supported almost at the center from the bottom surface, even when a heavy object or the like falls onto the storage lid, it will not break as described above, and its strength can be ensured.

Furthermore, as mentioned above, for vacuum cleaners that have a fixed part that repeatedly opens and locks each time you press the front top of the storage lid, when carrying the vacuum cleaner, even if the storage lid collides with a part of your body or furniture, etc. Even if the storage lid is not bent, the storage lid is difficult to bend because it rests on the bottom surface of the center of the storage lid.
The fixed part will not come off due to the impact.

Furthermore, by bending the front part of the storage lid using the abutment between the storage lid and the bulkhead as a fulcrum, the upper part of the fixed part can be reliably moved without causing the entire storage lid to flex as much as would be the case without a bulkhead. This has the effect of being able to be pushed downward.

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

In FIGS. 1 to 3, 8 is a main case having an upwardly open dust collection chamber (not shown) at the front and a motor chamber (not shown) at the rear.

A dust lid 9 covering the dust collection chamber is provided above the front of the main case 8, and is kept in the closed state by a buckle 10. Further, an upper body 11 is disposed above the rear portion of the main case 8 and covers the motor chamber from above and has a rotation axis for the dust cover 9.

A shelf nozzle 12 and a gap nozzle 13 for replacement are placed on the upper surface of the upper body 11,
A partition wall 14 with a convex cross section separating these two types of nozzles
is provided near the center of the upper body 11.

A storage lid 15 that covers the nozzles 12 and 13 from above is attached to be rotatable about a pivot point provided at the rear of the upper body 11.

Further, a brake button 16 for operating the brake of a cord reel (not shown) is arranged on the upper surface of the upper body 11 so as to be able to slide up and down,
Correspondingly, a hole is provided in the storage lid 15 so that the storage lid 15 can be operated even when it is closed.

Reference numeral 17 denotes a latch attachment portion for holding and fixing the storage lid 15, and a latch 18 attached to the latch attachment portion 17 is a latch claw 19 provided on the upper body 11.
The storage lid 15 is held and fixed by being fitted with the housing lid 15.

Furthermore, the structure of the storage part, partition wall 14, and storage lid 15 that accommodates the replacement nozzles 12 and 13 is explained in the first section.
This will be explained in detail based on FIGS.

The upper body 11 contains a shelf nozzle 12 and a gap nozzle 13, which are replacement nozzles.
A recess 20 is provided to match the cross-sectional shape of each nozzle. Further, a partition wall 14 having a convex cross section is provided at a portion separating the shelf nozzle 12 and the gap nozzle 13, and the top surface of the partition wall 14 is located at the center of the back surface of the storage lid 15.

Further, a latch 18 is attached to the front part of the storage lid 15 to hold and fix the storage lid 15 and the upper body 11, and as shown in FIG. to open the latch claw 19.
Repeat fixation. Here, the expansion wall 14 is connected to the latch 1
8 and the storage lid rotation axis, the latch 18 is located closer to the latch 18 than the midpoint between the storage cover rotation axis and the storage lid rotation axis.

Next, the function of the partition wall 14 that separates the nozzles of the replacement nozzle will be explained based on FIGS. 2 and 3.

When the storage lid 15 is closed, it is attached at position A as shown in FIG. At this time, the partition wall 14 provided on the upper body 11 is in contact with the central part of the back surface of the storage lid 15.

When the front central part of the storage lid 15 is pushed in the direction of arrow D, the storage lid 15 bends downward using the abutting portion on the top surface of the partition wall 14 as a fulcrum, and each time the storage lid 15 is pushed, the latch 18
repeats the opening and fixing of the latch pawl 19.

As mentioned above, since the partition wall 14 is in contact with the back surface of the storage lid 15, the storage lid 15 will not bend downward even if you press the area near E shown in FIG. 3 with your finger. , No whitening or cracking occurs on the storage lid 15.

Similarly, even if a heavy object falls near section E,
Since the upper surface of the partition wall 14 is supported, it will not break.

Furthermore, as mentioned above, a latch is provided at the front center of the storage lid 15, which can be repeatedly opened and fixed by pressing the upper part (FIG. 3F).
Since the partition wall 14 is in contact with the center of the storage lid 15, even if a part of your body or furniture hits the E section of the storage lid 15 when carrying the vacuum cleaner, the latch will not bend and open. However, the storage lid 15 will not open suddenly.

Furthermore, since there is no need to prevent the storage lid 15 from deflecting, ribs and bosses for preventing deflection are added to the storage lid 1.
By attaching the storage lid 15 to the storage lid 15, there will be no appearance defects such as sink marks caused by ribs on the surface during molding, and the number of defective molded storage lids 15 will be reduced.

Effects of the Invention As described above, the present invention has the following effects by bringing the partition wall with a convex cross section that separates the plurality of replacement nozzles into contact with the center of the back surface of the storage lid.

Since the center part of the storage lid is supported by the top surface of the partition wall from the back surface, it will not whiten or crack even if the center part is pressed with a finger or the like.

Even if a heavy object falls onto the top surface of the storage lid, the partition wall will absorb the impact as described above, and the storage lid will not break.

By pushing down the central part of the front part of the storage lid using the partition wall abutting part as a fulcrum, the fixing part can be reliably operated without bending the entire storage lid.

Even if your body or part of furniture collides with the storage lid when carrying the vacuum cleaner, the partition wall absorbs the impact and prevents the fixed part from opening due to malfunction.

Since ribs, bosses, and reinforcing ribs for preventing deflection are not required on the storage lid side, appearance defects such as sink marks caused by the ribs on the storage lid appearance are reduced, and the number of defective products is reduced.
