Description

Electric Cleaner {ELECTRICAL VACUUM CLEANER}

The present invention relates to an electric vacuum cleaner.

The conventional vacuum cleaner divides the electric blower chamber which accommodates an electric blower, and the cord reel chamber which accommodates a cord reel by a main body partition wall, as described, for example in Unexamined-Japanese-Patent No. 10-117976. The technique which provided the exhaust port in a part and provided the filter of high dust collection in this exhaust port is disclosed. And the cord reel is cooled by removing the carbon powder discharged | emitted from the electric blower by this high dust collection filter, and flowing clean gas | emission to the cord reel chamber.

However, in the technique described in Japanese Unexamined Patent Publication No. Hei 10-117976, the maintenance such as cleaning or replacing the high dust collecting filter has not been sufficiently considered. For this reason, the high dust-collecting filter which removed the carbon powder discharged | emitted from the electric blower clog | blocked, and there existed a fault that the ventilation resistance increases with use of a vacuum cleaner, and the suction performance of a vacuum cleaner falls. 9 and 10 of Japanese Patent Laid-Open No. 10-117976 disclose that a cover is installed above the electric blower chamber, and the cover is removed so that the filter can be removed and replaced. Since the electric blower chamber was in direct communication with the outside when the gas was removed, there was a fear that dust might enter the electric blower chamber.

And when removing a filter, it had to catch and remove the upper end of a filter, and it had a defect that it was difficult to take out a filter.

In addition, since the upper end of the filter must be exposed in order to remove the filter, this exposed part cannot be effectively used as a filter, so that the filter is likely to be clogged.

In addition, since a cover is provided above the electric blower chamber, parts such as a control device cannot be disposed in this portion, and this portion cannot be effectively used, resulting in an increase in the size of the cleaner body.

Accordingly, an object of the present invention is to provide an electric vacuum cleaner which solves the above problems and is excellent in water retention such as cleaning or replacing a filter, and further prevents intrusion of foreign matters into the vacuum cleaner body.

Further, below the electric blower 107, a filter accommodating chamber 124 serving as a fourth ventilation passage serving as a storage space of the filter 123 communicating with the ventilation passage 122 in the lower case is formed.

Exhaust from the electric blower 107 flows along the outer periphery of the electric blower 107 in each of the air passages 120 in the motor cover by dividing in the left and right directions as shown in FIG. 2 and openings 116 on the upper side. Pass through). The exhaust gas passing through the opening 116 flows along the outer circumference of the motor upper cover 111 in the upper case inner ventilation passage 121 that is classified in the left and right directions by the protrusion 117a and becomes the second ventilation path. The exhaust air that has passed through the ventilation path 122 in the lower case formed on the sidewalls of the motor lower cover 110 and the lower case 101 becomes the fourth ventilation path that serves as the storage space of the filter 123. Flows into. In the filter accommodating chamber 124, the exhaust gas which flowed in from the left-right direction of the ventilation path 122 in the lower case joins, and exhaust gas flows in through the filter 123 whole.

Next, the structure of the filter storage chamber 124 is demonstrated. A filter holding frame 125 is disposed between the ventilation path 122 in the lower case and the filter storage chamber 124 to suppress the upward movement of the filter 123 having the openings and the plurality of ribs arranged in a lattice shape. have. This filter holding frame 125 is provided so that a large foreign material, a user's finger, etc. may not enter. Although the filter 123 accommodated in the filter storage chamber 124 can arrange | position an electrostatic filter etc., in this embodiment, the HEPA filter with high dust collection efficiency is arrange | positioned. In addition, the filter holding frame 125 and the filter 123 are arrange | positioned inclined so that a front side may be lower and a rear side may be upper with respect to a cleaning surface (horizontal surface), as shown in FIG. The electric blower 107 used for this embodiment is arrange | positioned so that the rotating shaft may become a direction substantially parallel to a cleaning surface. In this state, the electric blower 107 has the blower part 107a at the front side, and the electric motor part 107b at the rear side, and the diameter (up-down direction in FIG. 1) of the motor part 107b is the blower part 107a. ) Is smaller in size than the diameter (up and down direction in FIG. 1). For this reason, the invalid space which becomes unnecessary space in the motor part 107b side generate | occur | produces. In the present embodiment, as described above, the filter holding frame 125 and the filter 123 disposed below the electric blower 107 are inclined so that the motor part 107b side is higher than the blower part 107a side. Since it is arrange | positioned, the invalid space is reduced using the space which generate | occur | produces on the motor part 107b side. Thereby, the cleaner main body 301 can be miniaturized. Reference numeral 127 denotes a front wheel disposed on the front side of the lower case 101, reference numeral 128 denotes a rear wheel disposed on the rear side of the lower case 101, and reference numeral 132 denotes a front and rear direction of the cleaner main body 301. The handle is rotatably installed.

The filter storage chamber 124 in which the filter 123 and the filter holding frame 125 are accommodated is covered by the filter cover 126 below. The structure of the filter cover 126 is mentioned later.

That is, the exhaust of the electric blower 107 which passed through the 4th ventilation path is classified by the cord reel partition wall 129. FIG. The exhaust flowed into the fifth ventilation path passes through the center portion of the cord reel 108 to cool the terminal portion of the cord reel 108. The exhaust flowed into the sixth ventilation path from the sixth ventilation path inlet 109a cools the power cord 108a wound on the cord reel 108. In addition, the exhaust gas that has passed through the fifth ventilation path and the sixth ventilation path is discharged from the exhaust port 131 installed to be inclined toward the rear side of the cleaner body 301.

According to this embodiment, since the ventilation path through which the exhaust of the electric blower 107 flows is made long, a noise can be reduced. In addition, since the filter is disposed in the air passage communicating the electric blower 107 and the cord reel 108, and the exhaust gas passing through the filter cools the cord reel 108, the carbon brush from the electric blower 107 is discharged. It is possible to prevent the power cord 108a of the cord reel 108 from being contaminated by carbon powder or fine dust passing through the dust bag 106.

Next, the structure of the filter cover 126 is demonstrated using FIG. 4 is a perspective view of the back surface of the filter cover 126.

The filter cover 126 is formed with an inclined portion 401 such that the rear side protrudes downward from the front side to the rear side of the cleaner body 301. On the rear surface of the filter cover 126, ribs 402a, 402b, and 402c supporting the filter 123 are formed at the center and left and right sides thereof. The ribs 402a, 402b, and 402c are formed so that their height increases from the front side to the rear side of the cleaner main body 301 so that the lower side of the filter 123 is located at the upper side. When the filter cover 126 is attached to the lower side of the cleaner body 301, the upper ends of the ribs 402a, 402b, and 402c are rear side from the front side of the cleaner body 301 as shown in FIG. It is located inclined so that a rear side may become an upper part over. In addition, the outer circumference of the filter cover 126 is covered by the front wall 403 and the side walls 404a and 404b. Rotating shafts 405 are provided on the side walls 404a and 404b, respectively. In the center portion of the front wall 403, a locking portion 406 is formed to hold a finger when the filter cover 126 is opened below the cleaner body 301. This locking part 406 is concave from the front wall 403 toward the rotating shaft 405 (from the front side to the back side of the vacuum cleaner main body 301). On the front side of the filter cover 126, as shown in FIG. 5 and FIG. 6, the front wheel 127 pivotally supported rotatably about the axis in the rotating shaft 501 is provided. The front wheel 127 is housed in a wheel housing portion 502 in which the bottom surface portion of the lower case 101 is concave upward. In addition, the wheel housing portion 502 is formed in a circular shape in accordance with the rotation of the front wheel 127. In addition, a cutout portion 503 is formed in the rear side of the wheel housing portion 502, a part of which is cut out. When the filter cover 126 is closed, the engaging portion 406 formed in the filter cover 126 is formed to cover the cutout portion 503. That is, the shape of the locking portion 406 is formed so as to coincide with the shape of the wheel housing portion 502. Thus, according to this embodiment, the wheel accommodating part 502 which provided the catching part 406 in the filter cover 126 and made this catching part 406 concave toward the upper side from the bottom face part of the lower case 101 is mentioned. ), It is easy for a user to catch a finger when opening the filter cover 126, thereby improving handling.

In addition, since it is not necessary to newly install a recess in which a finger is placed in order to raise the filter cover 126 in the bottom surface of the lower case 101, the unevenness of the bottom surface portion of the cleaner body 301 is less likely to damage the floor surface. In addition, since dust is hard to be clogged, it is easy to clean a vacuum cleaner.

Next, a configuration for attaching and detaching the filter 123 to the cleaner main body 301 will be described with reference to FIGS. 5 to 7.

FIG. 7 is a perspective view illustrating a state in which the filter 123 and the filter holding frame 125 are removed from the cleaner body 301.

In Fig. 5, the filter cover 126 is a cylindrical rotary shaft bore provided through the rotary shaft 405 provided on the side of the filter cover 126 in Fig. 4 through the lower case 301 of the cleaner body 301. By inserting into 901 (shown in FIGS. 9 and 10), the front side of the cleaner main body 301 is pivotally rotatably opened so as to open downward. Since the rotary shaft bore 901 is formed in the position where the rear wheel 128 is located among the side surfaces of the cleaner main body 301, it is covered by providing the rear wheel 128 in the side surface of the cleaner main body 301. As a result, the rotation shaft bore 901 and the rotation shaft 405 are not exposed to the outside, which does not cause a problem in appearance.

In addition, since the rotation shaft bore 901 can be formed using the side core mold by providing a projection or the like in the side core mold for forming the cylindrical member 902 for attaching the rear wheel 128, the rotation shaft bore It is possible to form simply without requiring a new mold for forming 901.

Moreover, by installing the rotating shaft bore 901 on the side of the cleaner main body 301, the filter cover 126 can be installed widely over the width direction (left-right direction) of the cleaner main body 301, and the filter storage chamber 124 similarly ) Can be installed widely over the width direction (left and right directions). In addition, since the filter 123 can also be installed in the width direction (left-right direction) similarly, a comparatively large filter can be used.

A hook 601 is provided on the front side of the filter cover 126, and is fixed by engaging with a coupling hole (not shown) formed in the lower case 301. In taking out the filter 123, first, the hook 601 of the filter cover 126 and the cleaner main body 301 are removed, a finger is inserted into the wheel housing 502, and the finger is caught by the locking portion 406. Hooked and pulled out below the cleaner body 301. The filter cover 126 is rotated about the rotation shaft 405, and as shown in FIG. 6, the filter 123 accommodated in the filter storage chamber 124 is exposed.

In fixing the upper case 102 and the dust collecting case 104, the screw boss 1403 of the upper case 102 is placed on the rear side of the screw boss 1402 of the dust collecting case 104 so that the screw 1404 is positioned. The upper case 102 and the dust collecting case 104 are fixed by inserting the screw boss 1402 and the screw boss 1403 in order.

15 is an external perspective view showing a state in which the rear side of the cleaner main body 301 is lowered. According to the present embodiment, the screw boss 1402 and the screw boss 1403 are upward when the dust collecting cover 103 covering the dust collecting case 104 is opened so that the rear side of the cleaner main body 301 is lowered. Since the screw 1404 is inserted into the screw boss 1402 and the screw boss 1403 facing upward, the assembly workability is improved because the screw 1404 can be fixed from the upper side with a driver or the like. In addition, since the rear side of the cleaner main body 301 is lowered, the assembly workability is further improved since the cleaner does not move during the assembly work.

Next, a drawing method of the power cord 108a will be described with reference to FIGS. 16 to 18.

FIG. 16 is a rear exterior perspective view of the cleaner main body 301, FIG. 17 is an enlarged view of a main portion of the rear exterior perspective view of the vacuum cleaner main body 301, and FIG. 18 is a state in which the rear side of the vacuum cleaner main body 301 is lowered. It is an external appearance perspective view.

In the cord reel 108 of the vacuum cleaner according to the present embodiment, as described above, the rotation axis of the cord reel is positioned in the same direction as the front-rear direction of the cleaner main body 301. For this reason, when pulling out the power cord 108a from the cord reel 108, it pulls out from the left-right direction of the cleaner main body 301. That is, since the withdrawal direction of the power cord 108a becomes a direction orthogonal to the moving direction of the cleaner main body 301, for example, when the power cord 108a is withdrawn to the rear side of the cleaner main body 301, the power cord 108a ) Is bent and difficult to withdraw. Therefore, in the present embodiment, the power plug receiving portion 1602 of the power plug 1601 attached to the distal end portion of the power cord 108a is formed to be open to the rear side, the upper side, and the lateral side of the cleaner body 301. did. Thereby, the power cord 108a can be pulled out in any direction of the rear side, the upper side, and the lateral direction side of the cleaner main body 301. 17, the upper side of the power plug housing 1602 is covered with the handle 132. As shown in FIG. As a result, the power plug 1601 is covered, and the appearance is excellent.

18 shows a state in which the rear side of the cleaner main body 301 is lowered. In this embodiment, since the power plug accommodating part 1602 of the power plug 1601 is opened with respect to the rear side, the upper side, and the lateral direction side of the cleaner main body 301 as mentioned above, the back of the cleaner main body 301 is carried out. Even when the side is lowered, it can be taken out from the upper side and the lateral side of the cleaner main body 301.

In addition, since the teeth of the power plug face the transverse direction of the cleaner main body 301 at the time of storing the power cord 108a, the floor surface may be damaged even when the rear side of the cleaner main body 301 is lowered. none.

19 shows a state in which the bumper is removed from the dust collecting cover 103.

The bumper 1901 is provided in the front side of the dust collecting cover 103. The bumper 1901 is fixed to the dust collecting cover 103 by inserting it into the grooves 103a and 103b formed in the dust collecting cover 103.

Background Art In recent years, vacuum cleaners are applied to the main body in order to prevent damage or to improve appearance design. For example, in FIG. 19, when the upper side 1902 of the dust collecting cover 103 is coated and the lower side 1901 of the dust collecting cover 103 is not coated, or the dust collecting cover 103 is applied. In the case of applying different colored coatings on the upper side 1902 and the lower side 1901, it was necessary to mask the boundary line with a tape or the like. In this case, it is necessary to mask every single vacuum cleaner, and since workability is inferior, it was difficult to mass-produce.

Therefore, in this embodiment, coating is performed on the upper side 1902 of the dust collecting cover 103 without masking. The boundary line between the place where the painting is applied and the place where the painting is not applied is covered by the bumper 1901. Thereby, even when the coating is performed without masking, there is no unsightly appearance, and thus an electric cleaner having improved designability can be provided.

As described above, according to the present invention, it is possible to provide an electric vacuum cleaner that is excellent in water-retaining properties such as cleaning or replacing a filter, and further prevents intrusion of foreign matters into the vacuum cleaner body.
