In addition, on the back surface of the housing 3a, a locking recess 3g is formed for fitting the locking member 13 and locking it to the main body 10.

Fig. 3 is a view from the direction X of Fig. 2. As shown in FIG. 3, the dust box 2 is of a cyclone type, and has a function of separating the air containing dust sucked from the introduction pipe 14 into dust and air and collecting the dust. In addition, the dust box 2 is arranged in front of the motor box portion 11 with the axial direction as the front-to-rear direction, and is provided with a storage portion 2a having a substantially cylindrical shape. The receiving portion 2a is provided with a receiving portion opening on the front surface. In addition, on the upper surface (side surface) of the dust box 2, a substantially rectangular inflow port 2b connected to the introduction pipe 14 is formed (refer to FIG. 2). The air containing dust flowing into this inlet 2b becomes a swirling flow. The centrifugal force acts on the dust and is separated into dust and air in the dust box 2. After that, the dust is separated into air, It is discharged from the rear (rear) of the dust box 2.

In addition, on the front surface of the dust box 2, the cover 2c, which is opened and closed when the dust accumulated in the dust box 2 is discarded, is rotatably relative to the receiving portion 2a via the pivot portion 2d. For support, the opening of the receiving portion is blocked by closing the cover 2c. Moreover, at the upper part of the cover 2c, there is provided a cover locking mechanism 2e for unlocking the cover 2c. In addition, the internal mechanism of the dust box 2 can be constructed based on Japanese Patent Application Laid-Open No. 2016-137165.

In addition, although not shown in the figure, the exhaust ports 16 are provided on the left and right sides.

Fig. 4 is a perspective view of the vacuum cleaner of this embodiment. As shown in FIG. 4, the vacuum cleaner 100 is such that the electric vacuum cleaner 2 is installed below the main body 10 and in front of the motor box 11. In this case, if the dust box 2 is mounted on the cleaner body 1, the lid locking mechanism 2e is hidden on the cleaner body 1 side. This is because when the lid locking mechanism 2e is installed on the opposite side (outer side), the lid locking mechanism 2e may be released during cleaning. However, the lid locking mechanism 2e Hidden on the side of the vacuum cleaner body 1 can prevent malfunction. For example, when cleaning under a sofa or under a bed in an upright state, the cleaner body 1 may be approached horizontally with respect to the ground. At this time, when the lid lock mechanism 2e is installed on the surface side, there is a possibility that the lid lock mechanism 2e may be released by contacting with the ground. The positions of the lid locking mechanism 2e and the pivoting portion 2d are not limited to this, and may be provided on the left and right with respect to the cleaner body 1.

In addition, the dust box 2 is provided with a cleaning brush 2s (refer to FIG. 2 and FIG. 3) so as to be detachable. The cleaning brush 2s is arranged at a position where it is difficult to see from the outside when the dust box 2 is mounted on the vacuum cleaner body 1. Therefore, the system is difficult to fall off during operation, and there is no need to separately store the cleaning brush 2s in a place different from the vacuum cleaner 100.

Moreover, when the airtight holding member 90 is attached to the cleaner body 1, the light emitting element 10c is covered by the airtight holding member 90. In other words, the inner diameter of the airtight holding member 90 is set in such a way that the light-emitting element 10c is positioned more inside than the airtight holding member 90.

Fig. 20A is a side view in a state where the cover is closed, in which the outer contour of the body is not shown in order to show the mechanism of the present embodiment. Fig. 20B is a side view in a state where the outer contour of the main body is not shown in order to show the mechanism part of the present embodiment, and the cover is opened. Fig. 21 is an exploded perspective view for showing the mechanism of this embodiment. Fig. 22 is a perspective view of the mechanism part of this embodiment with emphasis. At the lower part of the front of the main body 10, when the dust box 2 is mounted on the main body 10, the lid lock release button 2f provided at the lid lock mechanism 2e of the dust box 2 abuts A hook member (claw portion) 60 is provided at the location. The hook member 60 is attached to the hub 10e of the main body housing 10d so that the bearing portion 60a of the hook member 60 is fitted. The hook member 60 is provided with a spring accommodating portion 60b to which a torsion coil spring (elastic member) 61 is installed, and is held by the hook member 60 and the hub 10e. One end 61a of the torsion coil spring 61 is received by the flat portion 10f of the main body 10, and the other end 61b of the torsion coil spring 61 is received by the step Xb of the hook member 60. In addition, the hook member 60 is provided with a groove 60c of the front end 62a of the hook member 62. The cable member 62 is not a rod-shaped one that cannot be flexed, but a flexible one. For example, tie as a tie, etc. As a result, if tension is applied to the cable member 62, the hook member 60 rotates and the torsion coil spring 61 is twisted. As a result, the step portion Xb of the hook member 60 receives the restoring force of the torsion coil spring 61. When the tension of the cable member 62 disappears, the hook member 60 is tied back to the original position by the restoring force of the torsion coil spring 61.

Below the handle portion 12 and at the upper portion of the motor box portion 11, an operating member 63 for rotating the hook member 60 is provided. The claw portion 63a of the operating member 63 is hooked on the groove 11b of the motor box portion 11, and the operating member 63 has a slidable structure. The operating member 63 is provided with a groove portion 63b that hooks the rear end 62b of the cable member 62. If tension is applied to the operating portion 63c, the operating member 63 slides, and tension is applied to the cable member 62 to make The groove member 60 rotates and presses the lid lock release button 2f, whereby the lid 2c of the operating portion 2 can be opened. Here, by setting the length of the cable member 62 to be longer with respect to the distance between the groove portion 60c and the groove portion 63b, the position at which tension is applied to the cable member 62 when the operating member 63 is pulled can be adjusted. , And even if the operating member 63 is touched when there is no will to operate, it becomes a "margin" that can be provided until the mechanism is actually moved. The operating member 63 is provided in a range within which the user can extend and touch the finger from the state in which the handle 12 is held. Therefore, when the user opens the cover 2c of the dust box 2, the garbage stored in the dust box 2 can be carried out from the operation of the main body 10 with only one hand holding the handle 12. Of abandonment. In this embodiment, the hook member 60 is able to open the cover 2c of the operating portion 2 by rotating in the same direction as the operating direction of the operating member 63. If the consideration is only related to the effect of the present invention, the direction of action of the hook member 60 and the operating member 63 may be different. However, when operating in different directions, in order to transmit the force of the operating member 63 to the hook member 60, it is necessary to have a conversion mechanism, and the number of parts increases. Therefore, it can be said that by moving in the same direction, force transmission can be performed more simply.

A compression coil spring 64 is provided between the operating member 63 and the spring seat 11 of the motor case 11. As a result, tensile tension is applied to the operating member 63. If it is slid, the operating member 63 receives the restoring force of the compression coil spring 64 and slides to return to its original position. At this time, if the stroke of the operating member 63 is longer than the free length of the compression coil spring 64, when the operating member 63 is pulled, it will be able to be made without receiving the restoring force of the compression coil spring 64 Sliding range. With this, when a finger is caught on the operating member 63 during cleaning, etc., tension is accidentally applied to the operating member 63, it becomes necessary to proceed further by setting the operating member 63 from the middle of sliding the operating member 63. The operating force of the system is able to make the user notice that a misoperation has occurred. By attaching the torsion coil spring 61 and the compression coil spring 64 to both the hook member 60 and the operating member 63, the force used to open the cover 2c of the dust box 2 is greater than the mass of the body, for example, When the user releases the handle 12 while touching the operating member 63 with his finger, and applies a body mass load to the operating member 63, the lid 2c of the dust box 2 will not be opened. , And so on.

The cable member 62 is hooked on both ends of the hook member 60 and the operating member 63, and transmits the tensile force applied to the operating member 63 to the hook member 60. The cable member 62 is formed in a tie shape by polyester or the like. With this, the cord member 62 has a higher degree of freedom in shape than a resin molded product or the like, and can be easily arranged without making the cleaner body 1 larger. In addition, the method of hooking the two ends 62a, 62b of the cable member 62 to the hook member 60 and the operating member 63 is to consider the shape of the parts and the workability of assembly, etc., from knotting or winding into a circle, etc. Make your choice freely.

In addition, if the cable member 62 is made of a material with a high melting temperature (for example, polyester), and the hook member 60 and the operating member 63 are made of a material with a low melting temperature (for example, acrylonitrile butadiene styrene) If it is configured, it can be integrally molded and can prevent the cable member 62 from falling off from the hook member 60 and the operating member 63. Therefore, it is possible to omit the installation work of the cable member 62, and it is possible to prevent falling off due to external force or the like after the assembly during the transportation after installation.

In addition, the cable member 62 can also be used to discharge static electricity generated at the vacuum cleaner body. At this time, the cable member 62 is made of a conductive material. In addition, the hook member 60, the operating member 63, and the lid lock release button 2f provided at the lid lock mechanism 2e of the dust box 2 are composed of a resin material mixed with an antistatic agent or the like. When the user touches the operating member 63 while using the vacuum cleaner, the static electricity generated in the dust box 2 due to the sucked dust is through the hard-to-charge (low resistance) cover lock release button 2f. The hook member 60 and the cable member 62 flow all the way to the operating member 63. The static electricity flowing to the operating member 63 is discharged to the ground through the human body. As a result, the charge amount of the vacuum cleaner body is reduced, and it is possible to avoid shocks caused by static electricity.

In addition, the cable member 62 is constituted by a 2-core lead wire or the like, and is hooked to the aforementioned operation part, and the rear end of the cable member 62 is connected to the main body substrate 50. The hook member 60 is composed of two metal sheets, which are made of a material with high electrical resistance such as resin, and the metal sheets are connected to the front end of the cable member 62 respectively. The lid lock release button 2f is located at the place where the two metal pieces of the hook member 60 abut, and is provided with an energizing part. If configured in this way, the electrical signal emitted from the main body substrate 50 flows through the cable member 62 and the hook member 60 to the lid lock release button 2f. By allowing this electrical signal to flow to the other of the hook member 60 and the cable member 62 and to the body substrate 50, a closed loop is formed. By this, it is possible to determine whether the dust box 2 is installed in the cleaner body 1 by the main body substrate 50. Using this, it is possible to perform the operation as if the dust box 2 is not installed in the dust box 2 in such a way that it does not mistakenly operate the vacuum cleaner and cause the dust to enter the inside of the vacuum cleaner body 1. Controls such as making the vacuum cleaner inoperable when it is not installed.

Fig. 5 is a plan view of the vacuum cleaner of this embodiment. As shown in FIG. 5, the connecting portion 91b of the airtight maintaining member 90 is formed on the left and right sides with extension portions 91b1 and 91b1 extending toward the rear. A concave portion 91b2 is formed between the extended portion 91b1 on the left and the extended portion 91b1 on the right when viewed in plan. This concave portion 91b2 is fitted with the front end 10d1 of the protrusion 10d formed on the upper surface of the front end of the main body 10. By this, the positioning system of the front-rear direction and the left-right direction of the airtight holding member 90 with respect to the connection port 10a (refer FIG. 2) is performed.

The introduction pipe 14 formed at the main body 10 once extends diagonally to the right and then extends downward to be formed, and is connected to the inlet 2b of the dust box 2 (refer to FIG. 2). By this, it is possible to generate a swirling flow in the accommodating portion 2a of the dust box 2, and it is possible to effectively separate dust due to centrifugal force.

The width of each of the dust box 2 and the storage battery 3 is formed to be slightly shorter than the width W of the main body 10. In other words, the dust box 2 and the storage battery 3 are configured so as not to protrude from the side of the main body 10. With this, regardless of whether the user holds and cleans with the left hand or the right hand, the vacuum cleaner 100 can be smoothly moved in the front-rear direction, and the usability can be improved.

Fig. 6 is a sectional view taken along the line VI-VI of Fig. 5. In addition, FIG. 6 shows a state in which the airtight maintaining member 90 is removed from the cleaner 100. As shown in FIG. As shown in FIG. 6, an electric blower 40 is housed in the motor box 11 of the main body 10. Moreover, in the motor box part 11, below the electric blower 40, the main body board|substrate 50 (control board) which controls the cleaner main body 1 is accommodated.

The electric blower 40 is arranged horizontally so that the rotary drive shaft 40a faces the front-rear direction. In addition, the air discharged from the electric blower 40 flows to the main body substrate 50 arranged below the electric blower 40, and cools the main body substrate 50. In addition, the air that cools the main body substrate 50 partly cools the battery 3.

The main body substrate 50 is provided with an upper substrate 50a and a lower substrate 50b which are divided into upper and lower substrates and arranged in two stages, and are mainly mounted on the facing surfaces (the lower surface of the upper substrate 50a and the upper surface of the lower substrate 50b) Various parts. Most of the air discharged from the electric blower 40 flows in such a manner that the opposing parts (heat-generating parts) of the main body substrate 50 are cooled. In addition, the main body substrate 50 is covered by a flame-retardant resin case 51. The wind (air) discharged from the electric blower 40 flows from the rear side to the front side in the resin case 51, and then passes through the resin. The lower side of the bottom surface of the case 51 flows to the battery 3 side.

In addition, the electric blower 40 and the main body substrate 50 are arranged so as to overlap each other in the vertical direction. Therefore, the size in the front-rear direction can be shortened. In addition, the electric blower 40 is formed by protruding the motor box portion 11 on the handle portion 12 side, so that the size of the main body portion 10 in the front and rear direction (full length) can be shortened.

In addition, the electric blower 40 and the main body substrate 50 are positioned below the first gripping portion 12a1 of the handle portion 12. With this, when the user grips the grip portion 12a1 and operates it, since the center of gravity of the vacuum cleaner 100 is located near the bottom of the first grip portion 12a1, the vacuum cleaner 100 is used with the front end facing upward. In this case, the vacuum cleaner 100 can be held stably.

In addition, between the first holding portion 12a1 and the upper surface 11c of the motor box portion 11, a gap 12c having a width H1 for inserting a hand is formed. In addition, between the second gripping portion 12a2 and the back surface 11d of the motor box portion 11, a gap 12d of a larger width dimension H1 and a wider width dimension H2 is formed. In this way, when the first grip 12a1 is gripped and cleaned, the system can be held while the wrist is stretched, so the system can hold the first grip 12a1 without strong grip.
