Below, with reference to the accompanying drawings, a detailed description of preferred specific embodiments of a vacuum cleaner for dry / wet cleaning in accordance with the present invention.

As shown in FIG. 1, the hose connection device 100 of the present invention includes a hose holder 110, a hose connection 120, an auxiliary connection pipe 130, and an actuator assembly 140.

A hose holder 110 is installed in the upper part of the cleaner body 200, as shown in FIGS. 1-3. The hose holder 110 has the same radius of curvature as the vacuum cleaner body 200 (FIGS. 2 and 8) and has a centrally located air inlet 111. On the inner circumferential surface of the air inlet 111 there are a plurality of locking elements 112 in predetermined positions relative to each other, moreover, each of these elements has a locking hole 112a formed therein. On either side of the air inlet 111 of the holder 110, pairs of guide holes 113, 113 'are formed. A more detailed description of the locking element 122 and the guide holes 113, 113 'will be given below.

A hose connection 120 is connected to an air inlet 111 of the holder 110, one end of which is connected to a suction hose (not shown). The suction hose is connected to a remote suction brush (not shown) moving along the surface to be cleaned, and thereby forms a suction channel between the suction brush and the vacuum cleaner body 200. As shown in FIG. 1, the outer circumferential surface of the hose connection 120 has a plurality of locking protrusions 122 that are adapted to engage with the locking holes 112a of the locking elements 112 formed on the inner circumferential surface of the air intake opening 111. Therefore, the hose connecting pipe 120 is removably connected. with an air inlet 111 by means of locking elements 112 and locking protrusions 122. In addition, between the hose connection the first nozzle 150, which serves as a seal to prevent unwanted ingress of inflowing air through the connection, is located by the outlet pipe 120 and the air inlet 111.

As shown in FIG. 2, an auxiliary connecting pipe 130 is located between the hose holder 110 and the outer circumferential surface of the dust collector 300 and is movable between the first and second positions. A communication hole 310 is provided on one side of the dust collector 300 and is in fluid communication with the air inlet 111 when in a suitable position. The auxiliary connecting pipe 130 has a large diameter part 131 having a diameter larger than that of the air intake port 111, and a small diameter part 132 having approximately the same diameter as the communication hole 310. In addition, a circular groove 115 having a predetermined depth is made around the air inlet 111 of the hose holder 110, so that the large-diameter part 131 of the auxiliary connecting pipe 130 can be inserted into this groove, so that the pipe 130 can move between the first and second positions.

In the first position, the auxiliary connecting pipe 130 is removed from the dust collector 300 and moved to contact the air inlet 111 of the hose holder 110 (FIG. 2), and in the second position, the auxiliary connecting pipe 130 is moved to separate from the hose holder and to contact the dust collector opening 310 300 (Fig. 5).

An actuating unit 140 is designed to move the auxiliary connecting pipe 130 between the first and second positions. In particular, the actuating unit 140 allows the auxiliary connecting pipe 130 to be moved between the first and second positions when opening or closing the cover 400 (Fig. 8), which is mounted on top of the housing 200 vacuum cleaner and which can be opened and closed by turning around an axis. More specifically, when the cover 400 is closed, the actuator assembly 140 causes the auxiliary connecting pipe 130 to move to a second position, that is, to a position in which the small diameter portion 132 is in close contact with the communication hole 310, as shown in FIG. When the cover 400 is opened, the actuator assembly 140 causes the auxiliary connecting pipe 130 to move to a first position, that is, to a position in which the large diameter portion 131 is moved toward the air intake opening 111, as shown in FIG. In the first position, the auxiliary connecting pipe 130 is located at a predetermined distance from the outer circumferential surface of the dust collector 300, whereby the dust collector 300 is able to free the distal edge of the hose connecting pipe 120, which makes it possible to disconnect even when the hose connecting pipe 120 is not separated.

As shown in FIG. 1, the actuator assembly 140 comprises a pair of guide elements 142, 142 ′, which respectively and preferably include two first inclined protruding parts 141 having a predetermined inclination, second inclined connecting parts 143, 143 ′, guide pins 144, 144 'and elastic elements 145, 145', as shown in figa and 6B.

The pair of guide elements 142, 142 'is preferably made so that they are located on both sides of the auxiliary connecting pipe 130, respectively, having a first inclined protruding portion 141 located centrally between each of the guide elements 142, 142' and a larger diameter part 132 of the auxiliary the connecting pipe 130, and these guide elements 142, 142 'are located at each end of the auxiliary connecting pipe 130.

Each second inclined protruding part 143, 143 'has an inclination opposite and corresponding to the inclination of the opposite first inclined protruding part 141, and is adapted to come into contact with the first part 141. They are preferably mounted in the guide pins 144, 144', so that the opposite inclined protruding parts can contact each other. Meanwhile, in accordance with a preferred specific embodiment of the present invention, the second inclined protruding parts 143, 143 'are preferably made as elements separate from the guide pins 144, 144'. However, the second inclined protruding parts 143, 143 'in an alternative embodiment, can be made integral with the guide pins 144, 144'.

The guide pins 144, 144 'are mounted inside a pair of guide holes 113, 113' made on both sides of the hose holder 110, with the possibility of vertical movement in them. The guide pins 144, 144 'are comprised of a head portion 144a and a body portion 144b extending downward from the head portion 144a.

The elastic members 145, 145 'are preferably compression coil cylindrical coil springs, but may also take the form of rubber liners or other suitable means for deflecting the connecting pipe 130 in the desired direction. The elastic elements 145, 145 'are supported at one end on a protrusion 146 that fixes the spring (Fig. 3) and is located in direct accordance with the first inclined protruding part 141 of the hose holder 110 on its opposite side, and the other end on the inner wall of the vacuum cleaner body 200 ( not shown).

Figure 2 shows the second gasket 160, made around the communication hole 310 in the inner wall of the dust collector 300 to prevent the ingress of incoming air other than the incoming air that is sucked from the hose connection 120.

Below, with reference to figures 2-8, describes the operation of the vacuum cleaner for dry / wet cleaning, which uses the hose connection device corresponding to the present invention, as well as the hose connection device.

FIG. 8 shows a vacuum cleaner cover 400 for dry and / or wet cleaning that utilizes a hose connector in an open state, that is, when it is rotated about an axis.

As shown in FIG. 2, a pair of guide pins 144, 144 ′ is in a state in which they protrude vertically upward, since the guide pins 144, 144 ′ are vertically movable in the hose holder 110 so that they can occupy one of two vertical positions. As a result of the pins being in a state in which they protrude vertically upward, the auxiliary connecting pipe 130 moves to a first position in which a large diameter portion 131 is inserted into the groove 115 of the hose holder 110. Therefore, the small diameter portion 132 of the auxiliary connecting pipe 130 and the outer circumferential surface of the dust collector 300 are separated by a predetermined distance from each other.

The hose connecting device is triggered when the auxiliary connecting pipe 130 moves to the left under the action of the elastic force of the elastic element 145 located behind it, and the guide pin 144 moves upwardly of the first and second inclined protruding parts 141, 143, as shown in FIGS. 3 and 4.

By triggering the hose connection device, as shown in FIG. 8, since the auxiliary connecting pipe 130 does not prevent the dust collector 300 from moving upward when opening the cover 400, this dust collector 300 can be separated from the vacuum cleaner body 200 without having to separate the auxiliary connecting pipe 130 from the body 200.

Meanwhile, when the dust collector 300 is again installed inside the vacuum cleaner body 200 after emptying, and the lid 400 is closed, the end of the lid 400, which is farthest from the axis (distal end), is pressed onto the guide pin 144, as shown in FIGS. 5-7. As a result, the auxiliary connecting pipe 130 is pushed to the right, as shown in FIG. 5, and therefore moves to a second position in which its small diameter part 132 is in contact with the dust collector 300 in the vicinity of the communication opening 310. To create a more perfect seal of the communication channel, the outer edge of the portion 132 of small diameter is pressed against the surface of the second gasket 160 and is in contact with it.

That is, when the guide pin 140 is lowered, the auxiliary connecting pipe 130 moves to the right of the second and first inclined protruding parts 143, 141, which are affected by the elastic force of the elastic element 145.

When the cover 400 is opened again, the external force exerting pressure on the guide pin 144 is removed, as a result of which the auxiliary connecting pipe 130 is again moved to the first position, as shown in FIG. 2.

As described above in accordance with the present invention, when the cover 400 is opened, the auxiliary connecting pipe 130 moves to the hose connecting pipe 120. Therefore, the auxiliary connecting pipe 130 and the dust collector 300 are separated from each other by a predetermined distance. Therefore, the dust collector 300 can be separated from and removed from the vacuum cleaner body 200 without additionally separating the auxiliary connecting pipe 130 from the body 200. Therefore, the vacuum cleaner becomes more convenient to operate.

Although the invention has been illustrated and described with reference to preferred specific embodiments, it will be apparent to those skilled in the art that various modifications, alterations, replacements and changes are possible within the spirit and scope of the claims of the present invention limited by the appended claims.
