  However, in the conventional vacuum cleaner shown in Patent Document 1, the handle is attached separately to the front of the case. For this reason, when a user holds a handle and lifts the cleaner body, the handle may come off from the case, and the cleaner body may fall.

  In addition, since the handle is attached to the case so as to be inserted from below to above, when attaching the handle to the case, there is a need to turn it over so that the bottom surface of the case is turned upward. Not good.

  Furthermore, since the member constituting the handle also serves as the outline of the lower portion of the front surface of the main body of the vacuum cleaner (the member constituting the handle is exposed to the outside), design properties and a certain level of strength are required. For this reason, due to the balance between strength and design, the material and shape of the members constituting the handle are severely limited, and the degree of freedom of the material and shape is low, and in some cases the ease of holding the handle is sacrificed. End up. Further, when a member constituting the handle is manufactured by plastic molding or the like, the shape or the like is also limited by this manufacturing means.

  This invention was made in order to solve such a subject, and the 1st object is that even if a handle removes from a case when a user holds a handle and lifts a vacuum cleaner body, The vacuum cleaner which can prevent falling is obtained in advance.

  Moreover, the 2nd objective is to obtain the vacuum cleaner with favorable assembly manufacturability at the time of attaching a handle to the case of a cleaner main body. Furthermore, the third object is to obtain a vacuum cleaner that can more freely determine the material, shape, and the like of the members constituting the handle than before.

In the electric vacuum cleaner according to the present invention, the case body having the handle opening provided in the vicinity of the front end portion of the bottom surface that forms the outline of the vacuum cleaner main body, and the case body are provided as separate members. and a handle member having an opening in a side, the opening of the handle member, the inner side or found before Symbol structure that is connected to the opening for the handle of the case body.

  In the vacuum cleaner according to the present invention, it is possible to prevent the vacuum cleaner body from dropping even if the handle is detached from the case when the user holds the handle and lifts the vacuum cleaner body. There is an effect. Moreover, the effect that the assembling manufacturability when the handle is attached to the case of the vacuum cleaner main body is also achieved. Furthermore, there is an effect that the material and shape of the members constituting the handle can be determined more freely than before.

  In FIG. 1, a suction port body 1 is for sucking dust (dust) on the floor together with air from an opening formed downward. A connection portion for exhaust is provided at a substantially central portion in the longitudinal direction of the suction port body 1. One end (intake side) of the suction pipe 2 is connected to the connection portion of the suction port body 1. The suction pipe 2 is a straight member having a hollow cylindrical shape. One end (intake side) end of the connection pipe 3 is connected to the other end (exhaust side) end of the suction pipe 2. The connection pipe 3 is formed of a hollow cylindrical member that is bent halfway.

  The connection pipe 3 is provided with a grip portion 3a. The grip portion 3a is for the user of the vacuum cleaner to operate. The grip 3a is provided with an operation switch for controlling the operation of the electric vacuum cleaner. One end (intake side) end of the hose 4 is connected to the other end (exhaust side) end of the connection pipe 3. The hose 4 is made of a flexible bellows-like member.

  The other end (exhaust side) end of the hose 4 is connected to the cleaner body 6. More specifically, a hose connection portion 5 is formed at an end portion on the other side (exhaust side) of the hose 4. Corresponding to the hose connection portion 5, a hose connection port 6 a is formed in the vicinity of the front end portion of the cleaner body 6. And the hose 4 is connected to the cleaner body 6 by inserting and engaging the hose connection portion 5 with the hose connection port 6a.

  Furthermore, the cleaner body 6 will be described with reference to FIG. The vacuum cleaner main body 6 is for separating the dust from the air containing dust (dust-containing air) and discharging the air (clean air) from which the dust has been removed (for example, returning it to the room). The cleaner body 6 is provided with a dust collecting portion 6b that captures and collects dust (dust) in the dust-containing air that has flowed into the cleaner body 6.

  From the opening of the suction port body 1 to the dust collecting part 6b of the cleaner body 6 is formed continuously through the suction pipe 2, the connection pipe 3 and the hose 4. That is, the suction port body 1, the suction pipe 2, the connection pipe 3, and the hose 4 constitute a part of a suction path for allowing dust-containing air to flow into the dust collecting part 6 b of the cleaner body 6.

  The vacuum cleaner body 6 includes an electric blower (not shown). By this electric blower, a suction operation for sucking dust-containing air to the dust collecting part 6b of the cleaner body 6 is driven via the suction path described above. Rear wheels 6 c are attached to the left and right sides of the vacuum cleaner main body 6. Further, a pair of left and right front wheels 6 d are attached to the front of the bottom surface of the cleaner body 6.

  The vacuum cleaner main body 6 is roughly composed of the dust collecting portion 6b, the lower case 7, and the upper case 8 described above. The lower case 7 and the upper case 8 are combined to form a case body in which the above-described electric blower, wiring board, cord reel, and the like are accommodated. This case body forms an outline of the cleaner body 6. The dust collecting portion 6b is thus placed and mounted on the upper surface side of the case body constituted by the lower case 7 and the upper case 8.

  FIG. 3 is a view of the cleaner body 6 as seen from the bottom. As described above, a pair of rear wheels 6 c are provided on both the left and right sides of the vacuum cleaner main body 6, and a pair of front wheels 6 d are provided on the front of the bottom surface of the vacuum cleaner main body 6. In the vicinity of the front end portion of the bottom surface of the cleaner body 6, a handle portion is formed for use by the user when lifting the cleaner body 6. This handle portion is formed by providing a handle member 9 provided separately from the lower case 7 at the position of the handle opening 7 a formed in the lower case 7.

  Further, the handle portion will be described in detail with reference to FIGS. A handle opening 7a is formed in the vicinity of the front end of the bottom surface of the lower case 7 (in other words, the position between the front end of the bottom surface of the lower case 7 and the front wheel 6d). A handle member 9 is attached to a position corresponding to the handle opening 7 a inside the case body constituted by the lower case 7 and the upper case 8.

  One end of the handle member 9 connected to the handle opening 7a is opened. Moreover, the other end side of the handle member 9 is closed and has a bag path shape. On the inner surface side of the handle member 9, a handle inner space 9 a that is open at one end connected to the handle opening 7 a is formed.

  The handle part of the cleaner body 6 is formed by attaching the handle member 9 from the upper side of the lower case 7 so that the opening of the handle member 9 is connected to the opening 7a for the handle. In this state, the handle internal space 9a first extends upward in the case body from the handle opening 7a, and further extends forward in the case body. The front end of the handle inner space 9a reaches just inside the front end of the case body.

  Here, the shape of the case body formed by combining the lower case 7 and the upper case 8 is an inclined surface shape in which the upper surface side is higher at the rear and gradually lowers toward the front, and the lowest portion of the inclined surface. Forms the front end. And the lower surface side becomes a reverse inclined surface shape which gradually recedes back as it goes further below from this front end.

  As described above, the case body having such a shape is formed by combining the lower case 7 and the upper case 8. The front end of the case body is formed by the case front end portion 8a of the upper case 8, and the reverse inclined surface portion of the case body is formed by the reverse inclined surface portion 8b of the upper case 8.

  Then, the handle front surface portion 9b on the side opposite to the opening (the other end side) of the handle member 9 is disposed so as to face the reverse inclined surface portion 8b of the upper case 8 from the inside of the case body. Therefore, the handle front surface portion 9 b of the handle member 9 has an inclined shape that matches the reverse inclined surface portion 8 b of the upper case 8. Here, the inner surface of the reverse inclined surface portion 8b and the outer surface of the handle front surface portion 9b may be in contact with each other. You may make it the outer surface of the part 9b oppose.

  In general, the vacuum cleaner is often used in such a manner that the user pulls the vacuum cleaner main body 6 connected by the hose 4 with the grip portion 3 a of the connection pipe 3. In such a scene, in particular, the lower front portion of the cleaner body 6 is likely to collide with an obstacle on the floor surface. Therefore, in the lower front portion of the cleaner body 6, the reverse inclined surface portion 8 b of the upper case 8 and the handle front portion 9 b of the handle member 9 are arranged so as to overlap each other. It is possible to increase the strength and prevent damage or the like when colliding with an obstacle on the floor surface.

  When the case body is manufactured by combining the lower case 7 and the upper case 8, the handle member 9 is fixed to the lower case 7 before the upper case 8 is combined with the lower case 7. 6 to 8 are views showing a state in which the handle member 9 is fixed to the lower case 7 and the upper case 8 is detached from the lower case 7. FIG. 9 is a view showing a state in which the handle member 9 is removed from the lower case 7 or a state before the handle member 9 is attached to the lower case 7.

  As shown in these drawings, when assembling and manufacturing the case body of the vacuum cleaner body 6, first, the opening of the handle member 9 is aligned with the position of the handle opening 7 a of the lower case 7, and the lower case 7 The handle member 9 is fixed to the surface. At this time, the handle member 9 is attached from above the lower case 7. Therefore, it is not necessary to turn the top and bottom of the lower case 7 upside down in order to attach the handle member 9, and the assembly productivity is excellent.

  Further, as described above, in the state where the lower case 7 and the upper case 8 are combined, the handle front surface portion 9b and the reverse inclined surface portion 8b face each other. Therefore, when the upper case 8 is attached to the lower case 7 in a state where the handle member 9 is fixed, the attachment position of the upper case 8 can be adjusted using the handle member 9 as a guide, which is excellent in assembly manufacturability. . Furthermore, since these surfaces are reversely inclined surfaces, the upper case 8 can be aligned with the handle member 9 so that the positioning can be performed more conveniently.

  In addition, about the shape of the handle member 9, the non-opening side (the said other end side) of the handle member 9 is exhibiting the substantially arch shape which gradually narrows as it goes to a front-end | tip. By adopting such a shape, the strength of the handle member 9 on the side opposite to the opening (the other end side) can be increased, and when the hand is put into the handle inner space 9a, it fits well with the hand, It can be a handle that is easy to hold.

  Moreover, the handle part which consists of the opening part 7a for handles and the handle member 9 is arrange | positioned between the front-end part of the bottom face of the lower case 7, and the front wheel 6d as mentioned above. The front wheel 6d is composed of a pair of left and right wheels, a total of two wheels, and the wheels are divided into left and right sides of the bottom surface of the lower case 7 and arranged one by one. For this reason, for example, when only one front wheel 6d is disposed at the center of the bottom surface of the lower case 7, the user's hand may interfere with the front wheel 6d when the user puts his / her hand into the handle. However, as described above, the pair of front wheels 6d are arranged separately on the left and right sides of the bottom surface of the lower case 7, so that a protruding portion such as a wheel is not provided at the central portion of the bottom surface of the lower case 7. Therefore, it is possible to avoid interference when the user puts his hand into the handle.

  The vacuum cleaner configured as described above forms the outer body of the vacuum cleaner body, the case body having a handle opening provided near the front end of the bottom surface, and the case body are provided as separate members, And a handle member having an opening on one end side. The handle member is provided with the opening connected to the opening for the handle from the inside of the case body.

  When the user holds the handle, the user's hand is passed through the handle opening of the case body and then passed through the handle inner space of the handle member. Therefore, even when the user holds the handle and lifts the vacuum cleaner main body, the user can support the vacuum cleaner main body with the handle opening of the case body. It is possible to prevent falling.

  Moreover, the handle member is arrange | positioned inside the case body, and a handle member does not serve as the outline of a cleaner body. For this reason, the level of strength and designability required for the handle member is lower than that of the conventional handle member that also serves as the outer shell of the cleaner body. Therefore, restrictions on the material and shape imposed on the handle member are loose, and it is possible to configure the handle member with a material and shape that take into account the ease of molding of the member and the ease of holding the handle. .

  In addition, although the ABS resin is often used for the case body of the cleaner body, for example, a POM (polyoxymethylene, polyacetal) resin can be preferably used as the handle member.

Embodiment 2. FIG.
10 and 11 relate to Embodiment 2 of the present invention. FIG. 10 is a side cross-sectional view of the main part of the cleaner body, and FIG. 11 is an enlarged cross-sectional view of the main part of FIG.

  The second embodiment described here is a modification of the configuration of the first embodiment described above. In the first embodiment described above, the shape of the handle member is such that the space in the handle formed in the handle member extends forward in the case body. In contrast to this, in the second embodiment described here, the internal space of the handle formed in the handle member extends in the case body upward from the opening for the handle, but does not extend forward in the case body. It is not set up.

  That is, as shown in FIGS. 10 and 11, the handle member 9 is a separate member from the case body constituted by the lower case 7 and the upper case 8. Further, one end side of the handle member 9 is opened, and the other end side is closed to form a bag path. The handle member 9 is attached to the inside of the case body from the upper side of the lower case 7 so that the opening is connected to the opening 7a for the handle.

Thus, by attaching the handle member 9 to the lower case 7, the handle portion of the cleaner body 6 is formed by the handle member 9 and the opening 7 a for the handle of the lower case 7. In this state, the handle internal space 9a is arranged extending upward from the handle opening 7a in the case body.
Other configurations are the same as those of the first embodiment, and detailed description thereof is omitted.

  Even in the vacuum cleaner configured as described above, when the user has a handle, the user's hand is passed through the handle opening of the case body and then into the handle inner space of the handle member. Will be passed. Therefore, even when the user holds the handle and lifts the vacuum cleaner main body, the user can support the vacuum cleaner main body with the handle opening of the case body. It is possible to prevent falling.

  Moreover, it is not necessary to turn the top and bottom of the lower case upside down in order to attach the handle member, and the assembly and manufacturing are excellent. Furthermore, since the handle member is disposed inside the case body and the handle member does not serve as the outer shell of the vacuum cleaner body, restrictions on the material and shape imposed on the handle member are loose, and the member is molded. The handle member can be made of a material and a shape that take into account the ease of handling and the ease of holding the handle to the maximum extent.
