A stick-type electric vacuum cleaner is used by a user gripping a grip portion provided in a cleaner body. The gripping portion is generally provided at a portion near the rear of the cleaner body, and is operable to direct an extension pipe connected to the cleaner body and a suction port body connected to the tip thereof toward a portion to be cleaned below a floor surface or the like. However, when the portion to be cleaned located higher than the floor surface is cleaned, the distance from the grip portion to the extension pipe and the suction port body is long, and therefore it is difficult to lift the extension pipe and the suction port body. Therefore, there is a need for an electric vacuum cleaner that can easily assume a posture corresponding to the height of the vacuum-cleaned part.
Disclosure of Invention

For example, when cleaning a portion to be cleaned under the floor surface or the like, the user grips the first grip portion 14 as shown in fig. 4, and takes a first dust-cleaning posture in which the extension pipe 2 and the suction port body 3 face downward. In this first dust suction posture, when viewed from the user who grips the first grip 14, one side in the first direction is a front side lower side, the other side is a rear side upper side, one side in the second direction is a left side, the other side is a right side, one side in the third direction is a front side upper side, and the other side is a rear side lower side. The center of gravity G of the electric vacuum cleaner VC is located below the position of the first grip 14 gripped by the user. When the user operates the first setting unit 7, the control unit C operates the electric blower 5 in accordance with the operation of the first setting unit 7.
When a portion to be cleaned located above the floor surface is cleaned, the user grips the second grip 15 to bring the extension pipe 2 and the suction port body 3 into a second cleaning posture as shown in fig. 5. In this case, the suction port body 3 is preferably a lightweight member including a brush or the like. In this second dust collection posture, when viewed from the user who grips the second grip 15, one side in the first direction becomes the front side and the other side becomes the rear side, one side in the second direction becomes the left side and the other side becomes the right side, and one side in the third direction becomes the upper side and the other side becomes the lower side. Further, the extension pipe 2 and the suction port body 3 are located on the front side and the gravity center G of the heavy object such as the electric blower 5 and the battery 6 or the electric vacuum cleaner VC is located on the rear side with respect to the position of the second grip 15 gripped by the user. When the user operates the second setting means 8, the control means C operates the electric blower 5 in accordance with the operation of the second setting means 8.
The electric vacuum cleaner VC sucks dust-containing air from the dust-receiving portion into the dust collecting portion 4 by a negative pressure generated by the operation of the electric blower 5 acting through the main body suction port 101. The air separated and collected by the dust collecting unit 4 is sucked by the electric blower 5 shown in fig. 1 and discharged as exhaust air from the main body exhaust port 123 shown in fig. 2. With the exhaust of the electric blower 5, the heat of the battery 6 is drawn from the entire battery 6 and is discharged to the outside of the cleaner body 1 together with the exhaust air from the body exhaust port, thereby cooling the battery 6.
As described above, according to one embodiment, when a portion to be cleaned under a floor surface or the like is cleaned, the electric vacuum cleaner VC can be used with good operability by placing the suction port body 3 on the portion to be cleaned with the extension pipe 2 facing downward using the first grip 14 located farther from the extension pipe 2 with respect to the electric blower 5, and by positioning the center of gravity G of the electric blower 5 or the electric vacuum cleaner VC below the first grip 14 in the direction of gravity. On the other hand, when cleaning a portion to be cleaned which is higher than the floor surface, the second grip portion 15 is used which is closer to the extension pipe 2 with respect to the electric blower 5, and the electric blower 5 functions as a counterweight, so that cleaning can be performed in a posture in which the extension pipe 2 and the suction port body 3 are easily lifted. That is, according to the present embodiment, by using the first grip portion 14 and the second grip portion 15 separately according to the height of the desired portion to be cleaned, the electric vacuum cleaner VC can be easily set to an attitude suitable for cleaning depending on the height of each portion to be cleaned.
Further, since the suction unit 10 and the housing 12 are connected by the second grip 15, it is not necessary to integrally form the outer shape of the cleaner body 1 from the suction unit 10 to the housing 12 by synthetic resin or the like, and therefore an unnecessary structure is not required to be formed between the suction unit 10 and the housing 12, and an increase in size of the cleaner body 1 can be suppressed. Therefore, the mold for the outer periphery of the cleaner body 1 can be made smaller, and the manufacturing cost of the mold and the cost of the molded product can be suppressed.
Since the first grip portion 14 and the second grip portion 15 are disposed on the side distant from the extension pipe 2 and the side close to the extension pipe 2 with the center of the battery 6 as a reference, the extension pipe 2 and the suction port body 3 are located on one side and the battery 6 and the electric blower 5, which are heavy objects, are located on the other side in a state where the user grips the second grip portion 15, the battery 6 and the electric blower 5 function as counterweights, and the extension pipe 2 and the suction port body 3 are more easily lifted.
Further, by arranging the axial direction of the dust collection unit 4, the axial direction of the electric blower 5, and the second grip 15 substantially in parallel, the electric vacuum cleaner VC can be configured to be slim as compared with a case where at least one of the axial direction of the dust collection unit 4 and the axial direction of the electric blower 5 is inclined with respect to the second grip 15, and operability in a state where the second grip 15 is gripped can be improved.
Further, by making the second grip portion 15 of aluminum, the second grip portion 15 can have sufficient strength, and the electric vacuum cleaner VC or the cleaner body 1 can be made smaller and lighter.
Further, by disposing the socket 9 for external connection between the second grip 15 and the dust collection part 4 or the cleaner body 1, when the plug P is connected to the socket 9, the plug P is hidden between the second grip 15 and the dust collection part 4 or the cleaner body 1 and is not exposed to the outside of the electric vacuum cleaner VC or the cleaner body 1, and therefore, the plug P and the socket 9 can be protected from being damaged by an external force applied thereto by stepping on by mistake or the like.
Further, since the space S into which a part of the hand of the user gripping the second gripping portion 15 is inserted is formed between the second gripping portion 15 and the dust collection portion 4 or the cleaner body 1, the space S can be effectively used for the arrangement of the outlet 9.
Further, by disposing the second setting means 8 at a position on the opposite side of the second grip portion 15 from the first grip portion 14 such that the second setting means 8 is positioned in front of the hand that grips the second grip portion 15 and performs the dust suction operation, the second setting means 8 can be easily operated, and at least the on/off state of the electric blower 5 can be easily set by the second setting means 8.
