Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a vacuum cleaner, and more specifically, the present invention relates to a vacuum cleaner, and more specifically, to a vacuum cleaner that includes a main body consisting of an upper main body and a lower main body, and a dust suction device disposed inside the upper main body. The present invention relates to a vacuum cleaner including a blower and a dust collection chamber disposed within a lower main body.

Conventional technology Conventionally, in this type of vacuum cleaner, a cord storage part for storing a power cord is formed in a concave shape in the circumferential direction of the vacuum cleaner body. A cord plug is provided at the end of the cord to be loaded, and the entrance width of the cord storage section (
A device is known that stores the cord and holds the cord plug by adjusting the gap) and the thickness of the cord plug.

(c) Problems to be Solved by the Invention However, in the vacuum cleaner described above, it is difficult to wrap the cord around the cord because the entrance width of the cord storage section is limited. Furthermore, when the cord is stored, it is visible from the outside, which is undesirable in terms of appearance.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a vacuum cleaner in which the cord can be easily stored and the appearance performance is not impaired.

(d) Means for Solving the Problems and Their Effects The present invention includes the following two types of vacuum cleaners: a first vacuum cleaner and a second vacuum cleaner.

The first vacuum cleaner includes a device main body consisting of an upper main body and a lower main body, a dust suction blower disposed in the upper main body, and a dust collection chamber disposed in the lower main body. The electric sweeper includes a cord storage section provided on the top surface of the upper body, and a cord cover detachably attached to the top surface of the upper body covering the cord storage section and movable up and down by hand. and a compression coil spring that is attached to the inside of the cord cover, biases the cord cover toward road force, and applies biasing force in the engagement direction when the cord cover is in the lowest position. It is.

That is, the first vacuum cleaner is provided with a cord cover on the upper surface of the upper main body that covers the cord storage part and is detachable and can be moved up and down by hand, and also has a cord cover inside the cord cover. It is characterized by the attachment of a compression coil spring that biases against road forces and applies biasing force in the engagement direction when the cord cover is at the lowest position.

Here, for example, when the cord cover has a substantially rectangular planar shape, one compression coil spring is attached to each of the four corners of the lower surface of the flat portion of the cord cover.

Thus, when the coat cover is disengaged from the upper body and the cord cover is raised, the cord can be easily stored. Furthermore, when the cord cover is lowered and engaged with the upper main body, the cord stored in the cord storage section is hidden. Further, when the cord cover is lowered, the compression coil spring acts in a direction to engage the cord cover. For this reason, the cord cover becomes difficult to come off, and therefore there is no need to provide a protrusion or the like on the cord cover to prevent it from coming off, and the cord cover can be smoothly engaged and disengaged.

The second vacuum cleaner includes a main body consisting of an upper main body and a lower main body, a blower for collecting dust disposed in the upper main body, and a dust collection chamber disposed in the lower main body. The vacuum cleaner includes a cord storage section provided on the top surface of the upper main body, and a cord cover removably attached to the top surface of the upper main body to cover the cord storage section. A vertical annular rib provided on the inside, an upper opening groove provided in the cord storage portion into which the annular rib is rotatably inserted, and a locking hook provided in a downwardly protruding shape from the annular rib. , a locking notch provided in the upper opening groove and to which the hook is locked, and a locking and disengaging portion provided in the upper opening groove and locking the hook and the notch. This is a vacuum cleaner that does this.

That is, in the second vacuum cleaner, first, a cord cover is provided on the upper surface of the upper main body to cover the cord storage part and can be detached, and a vertical annular rib is provided on the inside of the cord cover.

Further, an upper opening groove into which the annular rib is rotatably inserted is provided in the cord storage portion, a locking hook portion is provided in a downwardly protruding shape from the annular rib, and the hook portion is locked in the upper opening groove. The present invention is characterized in that a locking notch is provided, and a locking and disengaging portion is provided in the upper opening groove to connect and disconnect the hook and the notch.

Thus, when attaching the cord cover, the annular rib is inserted into the upper opening groove, and the hook portion is engaged with the notch portion via the locking portion.

(E) Examples Hereinafter, the present invention will be described in detail based on two examples shown in the figures. Note that the present invention is not limited to these.

Example 1 This example relates to the first vacuum cleaner described above.

In FIGS. 1 and 2, reference numeral 1 denotes a vacuum cleaner main body as a device main body. The vacuum cleaner main body 1 consists of a case portion 5 as an upper main body and a caster base 3 as a lower main body. The case portion 5 has a built-in blower 4 for collecting dust. The caster base 3 has a built-in water tank [2] serving as a dust collection chamber. The case portion 5 and the caster base 3 can be attached to and detached from each other using a clamp 6.

A handle base 7 and a cord storage part 8 formed in a concave shape are provided on the upper surface of the case part 5. and,
A coat cover 9 that covers the cord storage section 8 is detachably attached to the upper surface of the case section 5. Four compression coil springs 11 are attached between the handle base 7 and the cord cover 9.

As shown in FIG. 6, the cord cover 9 has a hollow center with a circular shape in plan view, and is inserted into the handle base 7. The cord cover 9 is engaged with the handle base 7 so as to be movable up and down by hand using an engagement protrusion 10 provided on the annular rib and a compression coil spring 11. 12 is a handle, 13 is a cord, and 14 is a switch cover.

With the above configuration, when taking out the cord 13, the cord cover 9 is turned to the left by hand. Then, the engaging protrusion 10 comes off from the handle base 7, and the cord cover 9 is automatically lifted up by the compression coil spring 11. Then, the cord storage section 8 appears and the cord 13 can be taken out (FIGS. 4 and 5).

On the other hand, when storing the cord 13, wrap the cord 13 around the cord storage part 8, and turn the cord cover 9 to the right while pushing down the cord cover 9 by hand. Then, the engaging protrusion 10 engages with the handle base 7. At this time, the cord cover 9 is automatically moved in the engagement direction by the biasing force of the compression coil spring 11 and is engaged, and is held by the biasing force of the compression coil spring 11 (FIG. 3).

In this first vacuum cleaner, the biasing force of the compression coil spring 11 acts in the direction of closing the cord cover 9 when the cord 13 is stored, so it is possible to prevent the cord cover 9 from coming off. Further, since the cord cover 9 is difficult to come off, there is no need to provide a protrusion or a convex portion to prevent the cord cover 9 from coming off, and therefore the cord cover 9 can be smoothly engaged and disengaged.

Furthermore, since the cord cover 9 can be moved up and down by hand, the cord 13 can be easily stored in the cord storage section 8.

In addition, this vacuum cleaner has excellent durability compared to a vacuum cleaner in which the cord cover 9 is held with elastic claws or the like. Furthermore, when the cord cover 9 is closed, the gap between the case part 5 and the cord cover 9, that is, the entrance width of the cord storage part 8, can be reduced to zero, so the stored cord 13 is not visible from the outside, and therefore the appearance is not spoiled. do not have.

Example 2 This example relates to the second vacuum cleaner described above.

In FIGS. 7 to 9, reference numeral 20 represents a vacuum cleaner main body as a device main body. The vacuum cleaner main body 20 includes a case portion 22 as an upper main body and a caster base 25 as a lower main body. The case portion 22 has 30 built-in blowers for collecting dust. The caster base 25 has a built-in dust box as a dust collection chamber. and,
The case part 22 and the caster base 25 are connected by a clamp 26

The state when the cord 31a is stored is shown in FIG. At this time, the cord cover 21 and the case portion 22 are separated by a very small distance. Further, when taking out the cord 31a, the cord cover 21 and the case portion 22 are separated by a distance H as shown in FIG.

As shown in FIGS. 10 and 11, the cord cover 2
1 is provided with a vertical annular rib 35a.

A pair of elastic claw portions 35b, which protrude downward and are opposed to each other, are provided on a part of the annular rib 35a as a pair of earth mooring hook portions. On the other hand, the cord storage portion is provided with an annular upper opening groove 40 into which the annular rib 35a is rotatably inserted.

The upper opening groove 40 is provided with a pair of fitting grooves 36 that bulge outward, into which the elastic claws 35b are fitted. A pair of locking notches 38 in which the elastic claws 35b are locked are provided at the bottom of the upper opening groove 40 near the fitting groove 36. Furthermore, in the vicinity of the fitting groove part 36 of the upper opening f440, a notch is provided which passes through the fitting groove part 36 and the notch part 38 in order to engage and disengage the elastic claw part 35b and the locking notch part 38. A pair of engaging/disengaging portions 37 are provided facing each other.

FIGS. 12 to 17 are diagrams showing the positions of the elastic claws 91E35b when the cord cover 21 is opened, closed, and removed. That is, the cord cover 21 changes from the closed state (FIGS. 12 and 13) to the open state 1.
3 (FIGS. 14 and 15) When the cord force bar 21 is rotated, the movable range (H-h) of the engaging/disengaging portion 37 is determined by the biasing force of the compression coil spring 39. When it becomes necessary to remove the cord cover 21 for maintenance etc., as shown in FIGS. 16 and 17, the fitting groove 3
By rotating the cord cover 21 to 6, it can be removed from the engagement portion 37.

In this second vacuum cleaner, when the cord cover 21 is closed, the gap between the case part 22 and the cord cover 21 can be reduced to almost 0, so the stored cord 31a is not visible from the outside, and the cord 31a is not visible from the outside. All screws 34 are not exposed to the outside. Therefore, the appearance will not be impaired. Furthermore, since the cord cover 21 is detachably attached, the cord 31a can be stored in the cord storage section with a simple operation.

(f) Effects of the Invention According to the vacuum cleaner of the present invention, the cord can be easily stored and the appearance performance is not impaired.

In the first vacuum cleaner, it is possible to prevent the cord cover from coming off. In addition, there is no need to provide any protrusions or protrusions to prevent detachment, so the cord cover can be smoothly engaged and detached, and the cord cover is highly durable.

Furthermore, in the second vacuum cleaner, all the mounting screws are not exposed to the outside, so that the appearance is not spoiled.
