Description

Technical Field

[0001] The present invention relates to a vacuum cleaner that is used in a plurality of different positions. Background Art

[0002] In the prior art, rechargeable vacuum cleaners operate by removing dirt from surfaces through a vacuum generated by a motor driven by a battery pack. Rechargeable vacuum cleaners include a floor brush that cleans the floor through suction, a duct connected to the floor brush, and a cleaner body at the other end of the duct. The vacuum cleaner body includes a grip handle, a motor, a dust reservoir, a battery pack, and associated electronics.

[0003] In the prior art, an existing vertical rechargeable vacuum cleaner (i.e., a cordless stick vacuum cleaner) includes a vacuum cleaner body immediately behind a ground brush, a pipe connected to the vacuum cleaner body, and a handle at the other end of the pipe. In such a battery-rechargeable vacuum cleaner, when the battery is exhausted, it is necessary to connect a charging adapter to the vacuum cleaner or place the vacuum cleaner or the battery of the vacuum cleaner in a charging station connected to the charging adapter.

[0004] A traditional canister vacuum cleaner consists of a floor brush that removes dust from the floor, an extension duct connected to the brush, a handle located on the duct, a hose assembly connected to the end of the handle, and a main body. The hose assembly is connected to the main body and contains a dust container and an electric motor. In a traditional horizontal rechargeable vacuum cleaner, the main body, which includes the dust container and motor, moves on rollers. As the user cleans with the vacuum cleaner, the roller-like structure of the main body moves with the user. In a typical canister vacuum cleaner, the motor that generates suction to collect dust is powered by a cable connected to the main power cord. In this type of traditional electric horizontal vacuum cleaner, the length of the power cable determines the extent of the cleaning area. Rechargeable vacuum cleaners offer unlimited mobility because they are powered by an internal battery pack rather than a cable connected to the wall. Because the handle is located on the main body, which contains the dust container, motor, and battery pack, dust can be sucked from the floor by connecting the duct and floor brush to the main body, or by connecting small accessories to the main body, which can directly suck dust.

[0005] An advantage of rechargeable vacuum cleaners is that, thanks to the included battery pack, they allow users to clean the desired area without the need for continuous electrical connections. On the other hand, with existing rechargeable vacuum cleaners, the user must constantly carry the weight of the motor, container, and battery pack while cleaning. While this isn't a problem for short cleaning sessions, carrying the weight of the main body over extended cleaning sessions can be very tiring for the user. Because the main body, which houses the primary weight element of a conventional canister vacuum cleaner, moves on rollers, the user doesn't have to carry heavy components like the motor.

[0006] However, in conventional canister vacuum cleaners, since the motor is powered by a cable connected to the house's main power line, the length of the cable determines the width of the cleaning area. This makes it difficult for users to reach areas where the cable is insufficient. Furthermore, when users wish to move forward during use, the cable is difficult to move because it is connected to an outlet, which is a limiting factor.

[0007] In short, rechargeable vacuums are tiring to hold by hand due to their weight, while horizontal vacuums are limited because they require an electrical connection.

[0008] Purpose of the Invention

[0009] The object of the present invention is to provide a vacuum cleaner which can be used in a number of different positions and which avoids the above-mentioned disadvantages.

[0010] Another object of the present invention is to provide a vacuum cleaner which enables the suction unit to be adapted for upright use, so as to be used in an inclined position.

[0011] Another object of the present invention is to provide a vacuum cleaner that can be used easily and comfortably in a horizontal position by moving a suction unit, which includes a motor and a battery as a weight element, which is located on a main unit provided with rollers and is connected to the main body of the vacuum cleaner hose.

[0012] Another object of the present invention is to provide a vacuum cleaner having a long service life since a battery in the main body and a battery in the suction unit are charged simultaneously.

[0013] Another object of the present invention is to provide a vacuum cleaner in which dust is filtered twice by a cyclone structure.

[0014] Another object of the present invention is to provide a vacuum cleaner which provides a longer service life with sucked dust being filtered in both the main body and the suction unit.

[0015] Another object of the present invention is to provide a vacuum cleaner system that can be used by the user in a vertical position with or without a hose, or in a horizontal position on the main body, if desired. Summary of the Invention

[0016] The present invention relates to a vacuum cleaner comprising: a main body to which a vacuum cleaner hose can be attached and having a movable roller; a suction unit having a motor for sucking air, a filter for filtering the sucked air, and at least one battery. The vacuum cleaner further comprises a housing in the main body for housing the suction unit; the suction unit can be used in a vertical position in which the suction unit is removed from the main body, or in a horizontal position in which the suction unit is placed in the housing in the main body, depending on the user's preference; and an air intake channel formed in the main body so that a suction end of the suction unit can be received therein.

[0057] The invention relates to a vacuum cleaner (100) comprising a main body (10) to which a vacuum cleaner hose (25) can be connected and which has a movable roller (15); a suction unit (20) comprising a motor for sucking air, a filter for filtering the sucked air and at least one battery (22). The vacuum cleaner (100) comprises a placement shell (11) in the main body (10), which is suitable for placing a suction unit (20); the suction unit (20) can be used in a vertical position or a horizontal position according to the user's wishes, in the vertical position, the suction unit is removed from the main body (10), and in the horizontal position, the suction unit is inserted into the placement shell (11) in the main body (10), and a suction end (23) of the suction unit (20), when it is in the vertical position, a vacuum cleaner hose (25), more specifically a hose extension (26) can be attached to the suction end according to the user's wishes; and an air intake channel (12), which is located in the main body (10) in such a way that the suction end (23) of the suction unit (20) can be received therein, allowing air sucked into the vacuum cleaner (100) to be transferred to the suction unit (20).

[0058] The vacuum cleaner (100) of the present invention allows for multiple uses and can be used in a horizontal position with the suction unit (20) positioned on the main body (10) and in a vertical position with the suction unit (20) removed from the main body (10). In addition, the suction unit (20) can be used in two different ways, such as Figure 12 As shown, with or without the hose extension (26) connected.

[0059] As supported by the present drawings, the vacuum cleaner (100) can have 7 different types of embodiments. In the first three types of embodiments in Figures 1 to 6, the vacuum cleaner (100) includes a first type of cyclone (30) and a suction unit (20), which can be positioned at different positions. In the fourth type of embodiment of the vacuum cleaner (100) in Figures 7 to 9, there is no separate reservoir and the suction unit (20) is also located in the main body (10). Figures 10 and 11 show a fifth type of embodiment of the vacuum cleaner (100), in which the vacuum cleaner (100) has a second type of cyclone (40) placed in the main body (10). Within the scope of the present invention, there can be different embodiments in which the suction unit (20) is again positioned at different positions. Figure 14a -c shows a non-limiting sixth type of embodiment of the present invention, a vacuum cleaner (100) having a dust bag (60) and a placement housing (11) with an inclined bottom. Figure 16a and 19bA seventh type of embodiment of a vacuum cleaner (100) is shown, in which the main body (10) has a blocking member (70) connected below the placement shell (11) and configured to engage with the suction unit (20) so as to allow the suction unit (20) to be lifted vertically relative to the longitudinal axis (X) of the main body.

[0060] In a first embodiment of the present invention, air sucked from the floor by a floor brush (27) enters an air inlet nozzle (33) in a first cyclone (30) through a hose extension (26) and a vacuum cleaner hose (25). The cylindrical air inlet nozzle (33) is housed in a first type cyclone (30) designed to separate dust from the air. The incoming air first rotates along the inner wall of a first cyclone zone (32) within a reservoir (31). The air sucked in by a grille enters a plurality of second cyclone zones (321) from there. A plurality of cyclone separation elements may be provided in the second cyclone zones (321). The air is dispersed in the cyclone separation elements and further filtered inside each cyclone separation element and drawn through a common air gap zone. The common air gap zone may also have a filter, which is preferably covered and sealed by a sponge / fabric / special material. The air that has been filtered again is introduced into an air inlet channel (12) leading to a housing (11). The air intake passage (12) is constructed in correspondence with the suction end (23) of the suction unit (20), and allows the sucked air to enter the suction unit (20) from the suction end (23).

[0061] In a first type of vacuum cleaner (100), as can be seen in FIG1 , the placement housing (11) in the main body (10) is configured to be inclined toward the ground plane. The inclination can preferably be selected between 10° and 40°. This allows the user to slide the suction unit (20) into the main body (10) and bring it into the appropriate coupling position in an easier manner. Figure 3a and 3b As shown, when the suction unit (20) is mounted on the main body (10), the corresponding suction end (23) is received in the air inlet channel (12) and allows air to enter the suction unit (20) from the first type cyclone (30). In a preferred embodiment of the present invention, when the suction unit (20) is positioned, a locking structure for fixing the suction unit (20) to the main body (10) can be provided. The locking structure can be opened by pressing a latch located on the main body (10). The locking structure also ensures continuous energy transmission in the charging connector.

[0062] like Figure 2 As shown in FIG3 , when the suction unit (20) is mounted on the placement housing (11), the relative charging connector (161) on the suction unit (20) contacts the charging connector (16) on the main body. Figure 7aWhen the main body (10) is supplied with electric current through a suitable adapter (50), the battery (22) in the suction unit (20) is charged. The suction unit (20) is preferably provided with a battery section (21) at the bottom, and the corresponding battery (22) can be inserted into the battery section (21). The battery section (21) also forms the bottom of the suction unit (20) and is configured to contact the housing (11).

[0063] When the suction unit (20) is locked to the main body (10), it moves as a whole and the user can grasp the handle (24) in order to lift or move the vacuum cleaner (100). Figure 2 Utilizing a suction unit (20) housed in a housing (11), the sucked air is first received in a first type cyclone (30), and then passes through first and second cyclone zones (32) and (321) respectively into a suction end (23). Thus, the air entering the vacuum cleaner (100) is further filtered in a reservoir within the suction unit (20), and is sucked and discharged by a motor.

[0064] The first type cyclone (30) is detachably connected to a first type cyclone housing (13), which is preferably formed at the lower part of the main body (10). Dust sucked from the floor is first collected in a container (31) of the first type cyclone (30). The container (31) is designed so that the user can pull it out. In a preferred embodiment of the present invention, the first type cyclone (30) may include a bottom cover (34) that can be opened by a latch to clean the collected dust. The bottom cover (34) supported at one end is pivotally movable in a specific direction, thereby allowing dust accumulated therein to fall.

[0065] A second embodiment of the vacuum cleaner (100) of the present invention is Figures 4a to 5b The only difference from the first embodiment is that the bottom of the housing (11) is configured to be parallel to the ground plane on which the vacuum cleaner (100) will move, rather than inclined. Figures 6a to 6d As shown in FIG, the only difference from the first type of vacuum cleaner (100) is that the suction unit (20) is arranged perpendicularly with respect to the longitudinal axis (X) of the body. Figure 6d As shown, in this third type of embodiment, a placement housing (11) is formed on the main body (10), and the suction end (23) of the suction unit (20) extends to the first type cyclone (30) in a direction perpendicular to the ground plane. This embodiment ensures that the suction unit (20) is firmly held in the main body (10).

[0066] exist Figures 7a to 9bIn the fourth embodiment of the present invention, the vacuum cleaner 100 does not include a secondary dust filter. In the fourth embodiment of the present invention, air sucked from the floor by the floor brush (27) passes through the vacuum cleaner hose (25) and enters the main body inlet port (17). The cylindrical hollow main body inlet port (17) leads to the air inlet channel (12) in the main body (10) and is connected to the suction end (23) in the suction unit (20). As in the first type of embodiment, the placement housing (11) is inclined relative to the longitudinal axis (X) of the main body. In addition, when the suction unit (20) is placed on the placement housing (11), the relative charging connector (161) on the main suction unit (20) contacts the charging connector (16) on the main body (10). During this connection, a locking structure can also be provided, and the suction unit (20) can be locked. The locking structure can be opened by pressing the latch (18) located on the main body (10). Once locked to the movable body (10), the suction unit (20) moves as a whole and the user can grasp the gripping handle (24) of the suction unit (20) in order to lift or move the entire system.

[0067] like Figure 7b As shown, in the fourth type of embodiment of the present invention, air sucked by a suction unit (20) placed in a housing (11) is received into a vacuum cleaner (100) through a main body inlet port (17) and then through a suction end (23). The air received in the cleaner (100) is filtered in a container of the suction unit (20), and as a final step, the air sucked by the motor is exhausted.

[0068] exist Figure 10a and 11b In the embodiment of the present invention, a fifth type of embodiment is shown, using a second type cyclone (40) instead of the first type cyclone (30). In this fifth type of vacuum cleaner (100), air sucked from the floor by the floor brush (27) passes through the vacuum cleaner hose (25) and enters the main body inlet port (17). The air passing through the main body inlet port (17) is received by the cyclone inlet (43) in the second type cyclone (40) designed to separate dust from the air. In the second type cyclone (40), the air entering through the main body inlet port (17) passes through the cyclone inlet (43), after which the air rises on the slope (44) at the bottom of the reservoir (41). While dust and particles remain in the reservoir (41), air passes through a single cyclone suction duct (45) which enters the suction end (23) through the cyclone outlet opening (46) which is driven into the air inlet channel (12) in the body (10). A filter made of fabric / sponge / special material may also be provided.

[0069] The suction unit (20) is attached by driving it all the way into the placement housing (11), which has a bottom that is also inclined relative to the longitudinal axis (X) of the body. Once positioned, the opposing charging connectors (161) on the suction unit (20) come into contact with the charging connectors (16) on the body (10).

[0070] like Figure 11a As shown, the suction end (23) of the suction unit (20) is accommodated in the air inlet channel (12), and preferably, a locking structure can be provided to secure the suction unit (20) (which may be referred to herein as an upright vacuum cleaner) to the movable body (10). The locking structure can be opened by pressing a latch located on the body (10). Once connected, the suction unit (20) moves as a whole, and the user can grasp the handle (24) of the suction unit (20) in order to lift or carry the entire system. A locking structure is also required in the charging connector for continuous energy transmission.

[0071] Reference Figure 11a The air sucked in by the second type cyclone (40) placed in the second type cyclone housing (131) is first received in the single cyclone storage (41), and then enters the suction end (23) through the slope (44), the air single cyclone suction duct (45) and the cyclone outlet opening (46). The air entering the suction unit (20) is filtered again and is sucked in by the motor and discharged.

[0072] Reference Figure 10b , dust sucked from the floor is first collected in the single cyclone reservoir (41) of the second type cyclone (40). The second type cyclone (40) having the reservoir (41) is also designed so that the user can pull it out via the reservoir handle (42). The second type cyclone (40) can be pulled out and removed from the second type cyclone housing (131) in a vertical direction relative to the ground plane. In a preferred embodiment of the present invention, the second type cyclone may also have an upper cover (47) supported at one end and opened by the user.

[0073] In the vacuum cleaner (100) of the present invention, when the suction unit (20) is placed in the placement housing (11) in the main body (10), the relative charging connector (161) and the charging connector (16) contact each other. When the main body (10) is connected to the adapter (50), the battery (22) in the suction unit (20) begins to charge. In a preferred embodiment of the present invention, an audible or visual warning can be provided to notify the user when the battery (22) and the backup battery (221) (if provided in the main body (10)) are fully charged. When the battery (22) is fully charged, the adapter end (51) of the corresponding adapter (50) can be removed from the adapter housing (52) formed on the main body (10) for continued use.

[0074] For example, in a fourth type of embodiment of the present invention, the main body (10) is provided with a main body inlet port (17) to which the vacuum cleaner hose (25) can be sealingly connected. When the suction unit (20) is provided in the main body (10) as described above, the suction end (23) is associated with the main body inlet port (17). Similarly, as Figure 13 As shown, a vacuum cleaner hose (25) is connected to the main body inlet port (17), and a hose extension (26) preferably in the form of a tube is provided at the other end of the vacuum cleaner hose (25). The hose extension (26) preferably has a tube made of metal with a floor brush (27) at its end. Figure 12 A view of the suction unit (20) is shown, which is adapted for vertical use, wherein the suction end (23) can be directly connected to a hose extension (26). The user can replace the floor brush (27) with the hose extension as required.

[0075] Reference Figure 13 When operating a vacuum cleaner (100) having a suction unit (20), a user can hold a gripping area (251) on the vacuum cleaner hose (25) to clean. The main body (10) is provided with large opposing rollers (15) and at least one auxiliary roller (151) to allow the user to pull the vacuum cleaner (100) to a desired location. Since there is no cable connected to the wall, the user has no range restrictions on the cleaning area. Figure 3a As shown, the auxiliary roller (151) is configured to be located below the first type cyclone (30).

[0076] The main body (10) can also be used as a storage for spare accessories. The dust removed from the floor is collected in the suction unit (20). In several preferred embodiments of the present invention, at least one battery housing (14) is formed in the main body (10), in which an auxiliary battery (221) suitable for the suction unit (20) can be placed and charged. The battery housing (14) is in the form of an opening extending inward on the main body (10) and is easily accessible to the user. In a different embodiment of the present invention, the number of battery housings (14) can be increased. In the battery housing (14), the auxiliary battery (221) suitable for use in the suction unit (20) is charged. Advantageously, the present invention allows the battery (22) on the suction unit (20) and the auxiliary battery (221) on the main body (10) to be charged simultaneously when inserted into a charger using an adapter (50). This gives the user an advantage in terms of time.

[0077] In a preferred embodiment of the present invention, the battery (22) on the suction unit (20) and the auxiliary battery (221) on the main body (10) can be charged sequentially. When the suction unit (20) is placed in the main body (10), the battery (22) of the suction unit (20) starts to be fully charged first, and when it is fully charged, the auxiliary battery (221) starts to be fully charged. When the suction unit (20) is not attached to the main body (10), or when it is removed from the main body (10), the auxiliary battery (221) starts to be charged, or if it is being charged, the process continues. During the charging process of the auxiliary battery (221), if the suction unit (20) is inserted into the main body (10), the charging of the auxiliary battery (221) is suspended and the battery (22) in the suction unit (20) starts to be charged. In this embodiment of the present invention, the battery (22) in the suction unit (20) is charged first, while in different embodiments of the present invention, both the battery (20) and the auxiliary battery (221) can be charged simultaneously.

[0078] Reference Figure 14a -c, provides a sixth type of embodiment of the present invention, wherein the same suction unit (20) is positioned in the main body (10) and communicates with the air inlet channel (12) in the main body (10). In this sixth type of embodiment, no cyclone is provided, but a dust bag (60) is used for filtering. The dust bag (60) is provided with a dust inlet nozzle (61), and as Figure 14b As best shown in FIG, the corresponding dust inlet nozzle (61) is positioned facing the main body inlet port (17). The air sucked in by the suction unit (20) passes through the main body inlet port (17) and then enters the dust bag (60), where the relevant dust is first filtered. In the next stage, the filtered air enters the suction unit (20). This ensures that the reservoir in the suction unit (20) is used for a longer time and is filled at a later time. As shown in FIG. Figure 14cAs shown, a dust bag cover (62) may be provided directly above the dust bag (60) as part of the body (10). The dust bag cover (62) allows easy access to the dust bag (60) and easy replacement when it is full.

[0079] In a seventh type of embodiment of the present invention, the main body (10) has a blocking member (70) connected to the lower side of the housing (11), such as Figure 15 As shown, the blocking member (70) is configured to engage with the suction unit (20) to allow the suction unit (20) to be lifted vertically relative to the longitudinal axis (X) of the body. In addition, the blocking member (70) has at least two oppositely arranged supports (73) for connecting and allowing the pivotal movement of the blocking member (70).
