Description

  The present invention relates to a vacuum cleaner, and more particularly to a member that absorbs an impact.

  The member of the conventional vacuum cleaner is demonstrated using FIG. In FIG. 15, the outer surface of the vacuum cleaner main body 1 of the electric vacuum cleaner is composed of a main body cover lower 2, a main body cover upper 3, and a dust collector lid 5 that covers the dust collector 4 in an openable and closable manner. A hose (not shown) is connected to the front part, and an intake port 6 communicating with the dust collecting part 4 is provided. 7 is a protector which is a member formed of soft vinyl chloride, is formed in a substantially U shape, and is attached from the front part of the lower body cover 2 to both side parts. FIG. 15B is a cross-sectional view showing the structure of the protector 7 and its mounting portion. The upper portion of the protector 7 is fitted to the upper end 2a of the lower body cover 2, and the outer wall 2b of the lower body cover 2 and the protector 7 The lower end 7b of the protector 7 is brought into contact with the outer wall 2b of the lower body cover 2 so as to secure a space 7c between the rear surface 7a.

  With the above configuration, when the protector 7 collides with the wall of the room or the like during cleaning, the protector 7 is moved while the lower end 7b of the protector 7 slides downward along the surface of the lower body cover 2 as shown in FIG. It is bent inward to absorb the impact and prevent the vacuum cleaner main body 1 from being damaged, and at the same time, the wall is prevented from being damaged (for example, see Patent Document 1).

  FIG. 16 shows another conventional protector configuration. The protector 8 has a sealed hollow portion 8a, and receives an impact when the front and side portions of the cleaner body 1 collide with furniture during cleaning. It absorbs in the hollow part 8a (for example, refer patent document 2).

FIG. 17 shows another example of a conventional protector structure. Reference numeral 9 denotes a member made of soft vinyl chloride or the like, which is fitted to the upper edge of the lower body cover 2 and includes the protector 9 and the body cover. A hollow portion 8a is formed between the lower portion 2 and a plurality of protrusions 9a protruding in the hollow portion 8a in the direction of the outer wall of the main body cover lower portion 2 are integrally formed on the back surface of the protector 9 so that impact is applied to the protector 9. When added, the plurality of protrusions 9a breaks to absorb the impact. Further, there is a case in which the hollow portion 9a is filled with a foam such as urethane foam (see, for example, Patent Document 3).

  However, in the protector configuration of the conventional vacuum cleaner as shown in FIG. 15, the protector 7 is made of soft vinyl chloride having a relatively high hardness, so that the impact applied to the protector 7 is as shown in FIG. As shown, it is bent and absorbed inward, but since the size of the space 7c is limited, there is a problem that the bending allowance is not sufficiently secured and the shock cannot be sufficiently absorbed. Of course, if the space 7c is made larger, the shock absorbing ability is enhanced, but there is a problem that the protector 7 is greatly expanded outward and the main body 1 of the cleaner is enlarged.

  Moreover, in the protector structure of the conventional vacuum cleaner as shown in FIG. 16, it is necessary to seal the hollow portion 8a, which increases the manufacturing cost and gradually releases the air when used for many years. There was a problem that the shock absorbing ability was lowered. In addition, although the impact absorbing capacity depends on the material of the protector 8, it is largely determined by the air pressure in the hollow portion 8a. Therefore, if the air pressure is low, a strong impact cannot be absorbed, and a strong impact can be obtained. If the air pressure in the hollow portion 8a is increased so that it can be absorbed, manufacturing becomes difficult and air leakage is likely to occur.

  Moreover, in the protector structure of the conventional vacuum cleaner as shown in FIG. 17, since the hardness is different between the portion where the protrusion 9a of the protector 9 is provided and the portion where it is not provided, A difference occurs in the shock absorption capacity. In addition, when an impact is applied to the surface of the protector 9 from obliquely below or obliquely above, the protrusion 9a is smoothly bent and absorbed, but the impact is absorbed. When 9a is first compressed and exceeds its limit, it suddenly breaks down, causing a problem that shock absorption is not performed smoothly. Also, in the case where urethane is filled in the hollow part of a member made of soft vinyl chloride, it is transmitted to urethane through a soft vinyl chloride part that is relatively hard and has no cushioning property when it receives external force. The shock absorption was bad.

  The present invention solves the above-mentioned conventional problems, and absorbs an impact at the time of a collision with a wall, furniture, etc., and can prevent damage to the wall, furniture, etc., damage to the outer shell, etc. The purpose is to provide.

  In order to solve the above-described conventional problems, the vacuum cleaner of the present invention has a member having a foamed resin portion exposed on the surface, and the shape of the member is stabilized and the softness is uniform over the entire member.

Therefore, even if the vacuum cleaner body 10 collides with furniture, pillars, walls, etc. when the vacuum cleaner body 10 travels, the shock is absorbed by the softness of the foamed resin, so that the furniture, pillars, walls, etc. are damaged. The vacuum cleaner main body 10 is not damaged. Further, since the entire portion to which the impact (force at the time of collision) of the protector 26 is applied is formed of an exposed foamed resin material, the impact can be uniformly absorbed regardless of the portion of the protector 26 where the impact is applied. There is no difference in shock absorption capacity.

  In addition, as a foamed resin material, a urethane-based or ethylene-based resin material with excellent resilience characteristics can be used to reliably absorb shocks, and foam molding can be performed at a relatively low temperature. The temperature change is reduced, the molding distortion is suppressed, and a highly accurate member can be obtained.

  Further, the outer periphery of the dust box 24 is formed of a transparent or translucent material, and the openings 26b provided on both sides of the protector 26 are positioned in the portion. Therefore, the dust collection of the dust box 24 is performed through the openings 26b. It is easy to use because there is no need to remove the dust box 24 every time and check the dust accumulation inside the unit.

  Further, by integrally molding the locking member 26d formed of hard resin or metal with foamed resin, the protector 26 can be fixed and attached to the outer portion of the protector 26 very easily and reliably.

  In the present embodiment, the locking member 26d is formed of a resin material. However, the locking member 26d may be formed of a metal, and the foamed resin portion 26c may be molded integrally therewith.
