Description

Vacuum cleaner head and vacuum cleaner equipped with the same

[0001] The present invention relates to a vacuum cleaner, and more particularly, to a mop vacuum cleaner for cleaning a floor surface in a wet manner.

[0002]

[0003] In general, a cleaner is a device that cleans by sucking up or wiping away dust, contaminants, etc.

[0004] Vacuum cleaners can be classified into manual vacuum cleaners that perform cleaning while being moved by the user, and automatic vacuum cleaners that perform cleaning while moving on their own.

[0005] Manual vacuum cleaners can be divided into corded and cordless types depending on the presence or absence of a power line, and automatic vacuum cleaners are mainly cordless and are called robot vacuum cleaners and artificial intelligence vacuum cleaners.

[0006] Additionally, vacuum cleaners can be classified into handheld vacuum cleaners and stick vacuum cleaners depending on their purpose and shape.

[0007] Handheld vacuum cleaners are lightweight and short, and are mainly used to clean small areas such as desks, sofas, and car interiors by holding them in your hand.

[0008] Stick vacuum cleaners are long, with a stick connecting the handle to the main body of the vacuum cleaner, and have the advantage of allowing people to clean wide spaces without having to bend over.

[0009] Meanwhile, the method of cleaning the floor can be broadly divided into dry cleaning and wet cleaning.

[0010] Dry cleaning is a method of cleaning by sweeping or sucking up dust and contaminants, while wet cleaning is a method of cleaning by wiping or sucking up dust and contaminants using water.

[0011] Among these, there is a wet mop cleaner that can supply water to the mop.

[0012] Mop cleaners can be classified into two types: the spin mop, which rotates the mop parallel to the floor, and the rolling mop, which rolls the mop on the floor like a wheel.

[0013] In this regard, International Patent Publication No. WO 2024 / 069407 A1 discloses a vacuum cleaner head using a rolling mop-type mop. The vacuum cleaner head includes a clean water tank that supplies clean water to the mop, and a waste water tank that sucks up and stores dirty water after cleaning the floor.

[0014] The mop cleaner in the form of a rolling mop receives clean water from a clean water tank and cleans the floor by rolling it, and the waste water and contaminants from cleaning the floor are separated from the rolling mop and stored in the waste water tank.

[0015] However, the conventional rolling mop type mop cleaner has a problem in that the waste water tank overflows and waste water leaks out of the cleaner.

[0016] Additionally, rolling mop-type mop cleaners use a scraper to scrape the wastewater contained within the mop and cause it to fall into a wastebasket, essentially squeezing it out. Consequently, they fail to actively remove moisture from the mop, leaving residual moisture on the floor during and after the cleaning process.

[0017]

[0018] The present invention provides a vacuum cleaner head capable of preventing the problem of sewage leaking out due to overflowing of a sewage tank, and a vacuum cleaner equipped with the head.

[0019] In addition, the present invention provides a vacuum cleaner head and a vacuum cleaner equipped with the head, which can improve the problem of moisture remaining on the floor surface during or after the cleaning process by actively removing moisture from the rolling mop and storing it in a sewage tank.

[0020]

[0021] The present invention provides a head for a vacuum cleaner, comprising: a rolling mop; a fresh water tank for supplying fresh water to the rolling mop; a sewage tank for receiving sewage; a housing for receiving the rolling mop, the fresh water tank, and the sewage tank; and a suction pipe coupled to the sewage tank for forcibly sucking sewage from the rolling mop and discharging it into the sewage tank.

[0022] The above sewage tank may further include a water level detection unit installed to detect sewage overflow.

[0023] The above water level detection unit may include an electrode sensor.

[0024] The above suction pipe can be installed so that the positions of the suction port and the discharge port have a U shape.

[0025] The above exhaust port may be located at a lower height than the intake port.

[0026] The above electrode sensor can be installed parallel to the height of the discharge port of the above suction pipe.

[0027] The system may further include a control unit that generates a notification signal when a certain amount of sewage is filled in the sewage tank through information obtained from the electrode sensor.

[0028] It may further include a pump installed in the above housing and providing vacuum pressure to the clean water tank and the waste water tank.

[0029] The above suction pipe can forcibly suck up wastewater through vacuum pressure provided from the pump and discharge it into the wastewater tank.

[0030] Meanwhile, the present invention provides a vacuum cleaner comprising: a main body; a connecting portion extended from the main body; and one of the above-described vacuum cleaner heads detachably mounted to the connecting portion.

[0031]

[0032] According to the vacuum cleaner head of the present invention and the vacuum cleaner having the same, the problem of sewage leaking out due to overflowing of the sewage tank can be prevented.

[0033] In addition, according to the vacuum cleaner head of the present invention and the vacuum cleaner having the same, the problem of moisture remaining on the floor during or after the cleaning process can be improved because moisture is actively removed from the rolling mop and stored in a waste tank.

[0050]

[0051] FIG. 1 is a perspective view of a vacuum cleaner head and a vacuum cleaner having the same according to one embodiment of the present invention.

[0052] As illustrated in Fig. 1, a cleaner (1) according to one embodiment may be configured to include a main body (100), a connection part (200), and a head part (300). In addition, the cleaner (1) according to the embodiment may be implemented in a wireless, wired, manual, automatic, etc. manner.

[0053] The main body (100) may be equipped with a handle and various operation buttons to control the operation of the vacuum cleaner. The main body (100) may include a display unit for indicating the operation status, a suction motor for providing vacuum pressure, a dust bin for containing dust and contaminants, a battery for supplying power to the suction motor and / or the head unit (300), etc. In addition, although not shown, the main body (100) may be equipped with a display, a speaker, etc.

[0054] The connecting portion (200) is connected to the main body (100) and can serve as a passage for providing vacuum pressure to the head portion (300). For example, the connecting portion (200) can be formed in the shape of a bar of a certain length, allowing the user to clean without bending over.

[0055] That is, the connecting part (200) may be called a stick, a bar, etc. Accordingly, the vacuum cleaner (1) of the present embodiment including the connecting part (200) may also be called a stick-type vacuum cleaner.

[0056] The head part (300) is configured to be detachable and forms the part that directly performs cleaning. The head part (300) may be referred to as a cleaning head, head unit, cleaner nozzle, etc.

[0057] The head unit (300) may be configured with a dry cleaning head and a wet cleaning head. Users can perform cleaning in a desired manner by replacing various head units (300) as needed.

[0058] The head (300) of this embodiment is a wet cleaning head and constitutes the cleaning head (300) of the cleaner (1).

[0059]

[0060] Meanwhile, FIG. 2 shows an enlarged view of the vacuum cleaner head of FIG. 1.

[0061] As illustrated in FIG. 2, a head (300) for a vacuum cleaner according to the present embodiment may be configured to include a housing (301), a fastening rod (302), and a joint (303).

[0062] The housing (301) can form the outer shape of the head (300) for the vacuum cleaner. Specifically, the housing (301) forms a part in which a rolling mop (310), a fresh water tank (340), a waste water tank (320), a pump (330), etc., which will be described later, are installed, and can constitute the main body of the head (300) for the vacuum cleaner.

[0063] For reference, the direction used in the present invention is explained as follows.

[0064] In the present invention, the direction of the vacuum cleaner head (300) can be defined based on the waste tank (320). Specifically, the direction in which the rolling mop (310) is arranged based on the waste tank (320) can be referred to as the front of the vacuum cleaner head (300), and the opposite direction can be referred to as the rear. In addition, based on the state in which the vacuum cleaner head (300) is placed on the floor (surface to be cleaned), the direction away from the floor can be referred to as upward (upper side), and the direction approaching the floor can be referred to as downward (lower side).

[0065] The fastening rod (302) may include a detachable configuration as a part that is fastened to the connecting portion (200) of the vacuum cleaner (1). For example, the upper portion of the fastening rod (302) may be inserted into one end of the connecting portion (200) of the vacuum cleaner (1) and then fixed by a fixing means.

[0066] The joint (303) is located between the housing (301) and the connecting rod, and can provide a degree of freedom so that the housing (301) can move freely in all directions, such as up, down, left, and right, with respect to the connecting rod (302). Accordingly, the vacuum cleaner head (300) can perform cleaning while moving freely on the floor.

[0067]

[0068] FIG. 3 is a drawing schematically showing the main components of the water purifier head of FIG. 2, and FIG. 4 is a side view illustrating the operation of the main components of FIG. 3.

[0069] As shown in FIGS. 3 and 4, a head (300) for a vacuum cleaner of one embodiment may be configured to include, more specifically, a rolling mop (310), a fresh water tank (340), a waste water tank (320), a pump (330), and a suction pipe (400).

[0070] At this time, a suction pipe (400) may be placed at the rear of the rolling mop (310), a sewage tank (320) may be placed at the rear of the suction pipe (400), and a clean water tank (340) and a pump (330) may be placed at the rear of the sewage tank (320). At this time, the pump (330) and the clean water tank (340) may be placed at the rear of the sewage tank (320), but may be placed left and right. For example, the pump (330) may be placed at the left, and the clean water tank (340) may be placed at the right, but this is not limited to the case, and the left and right may be switched.

[0071] This arrangement has the advantage of allowing the pump (330) to be placed close to both the clean water tank (340) and the waste water tank (320), while maintaining a compact overall size.

[0072] The rolling mop (310) can be installed rotatably within the housing (301). For example, the rolling mop (310) can be positioned forward of the vacuum cleaner head (300). The rolling mop (310) can receive fresh water from the fresh water tank (340) and clean contaminants on the floor while rotating axially forward / reversely by a motor (not shown).

[0073] For example, the rolling mop (310) may be formed in an overall cylindrical shape, but may be formed in a hollow shape inside, and a motor (not shown) may be provided inside the hollow shape. That is, the rolling mop (310) may be applied with an in-wheel type motor, and may be rotated by receiving power from the motor (not shown) through at least one gear. With this configuration, the overall volume of the cleaner head (300) can be reduced, and there is an advantage in that the motor (not shown) can be protected from moisture that may be scattered during the cleaning process of the rolling mop (310).

[0074] In addition, the rotation axis of the rolling mop (310) can be positioned along the left-right direction of the housing (301). Accordingly, as the user operates the cleaner head (300) in the forward-backward direction, contaminants on the floor can be cleaned, and the contaminants can be discharged into the waste tank (320) positioned at the rear of the rolling mop (310).

[0075] Rolling mop (310) can be called a mop, a rotating mop, a rolling mop, a rotating roller, etc.

[0076] The clear water tank (340) may be configured as a container for storing clear water, i.e., clean water. The clear water tank (340) may supply clear water to the rolling mop (310) or the bottom surface.

[0077] The fresh water contained within the fresh water tank (340) may include tap water, purified water, cleaning solution, etc. As illustrated in Fig. 4, a supply pipe (341) for supplying fresh water to the bottom surface or rolling mop (310) may be connected to the fresh water tank (340).

[0078] Alternatively, depending on the embodiment, one side of the supply pipe (341) may be connected to the pump (330). Accordingly, the fresh water contained in the fresh water tank (340) may pass through the pump (330) and be discharged to the floor or rolling mop (310) via the supply pipe (341).

[0079] In addition, the water tank (340) can be detachably mounted on the housing (301). For example, the water tank (340) can be implemented in various shapes such as a cylinder, a rectangular parallelepiped, an elliptical cylinder, a triangular cylinder, etc.

[0080] As another example, the water tank (340) may be formed integrally with the housing (301), but may be detachably mounted to the pump (330).

[0081] The sewage tank (320) may be configured as a container for receiving sewage. The sewage tank (320) may receive sewage and contaminants contained in the rolling mop (310) after cleaning. For example, the sewage tank (320) may be implemented in various shapes, such as a cylinder, a rectangular parallelepiped, an elliptical cylinder, or a triangular cylinder.

[0082] The pump (330) is installed in the housing (301) and can provide vacuum pressure to the fresh water tank (340) and the waste water tank (320). As illustrated in FIG. 4, the pump (330) can be connected to the fresh water tank (340) and the waste water tank (320) via a first vacuum connection pipe (L1) and a second vacuum connection pipe (L2), respectively. Here, the connection of the pump (330), the fresh water tank (340), and the waste water tank (320) is a conceptual representation, and can be interconnected to provide vacuum pressure in various forms through known methods.

[0083] For example, the first vacuum connection pipe (L1) connected to the pump (330) may be connected to the suction pipe (400) to provide vacuum pressure to the suction pipe (400), although this is not shown in detail.

[0084] In addition, the second vacuum connection pipe (L2) connected to the pump (330) can suck in fresh water from the fresh water tank (340) and deliver it to the supply pipe (341), thereby supplying and spraying fresh water to the floor surface or the rolling mop (310).

[0085] That is, depending on the embodiment, the pump (330) may be connected to both the first vacuum connection pipe (L1), the second vacuum connection pipe (L2), and the supply pipe (341).

[0086] Accordingly, in the present invention, a fluid force can be provided to the clean water in the clean water tank (340) through one pump (330), and at the same time, a suction force can be provided to suck the sewage into the sewage tank (320).

[0087] In contrast, the pump (330) may be connected to both the first vacuum connection pipe (L1), the second vacuum connection pipe (L2), and the supply pipe (341), and may further be provided with a valve that selectively opens and closes the first vacuum connection pipe (L1) and the second vacuum connection pipe (L2). In this case, only the supply of fresh water may be enabled, and only the suction of waste water may be enabled, as needed. The "A" area, which is the space between the wastewater tank (320) and the rolling mop (310), may include a scraper (not shown) that scrapes the wastewater contained in the rolling mop (310) and causes it to fall into the wastewater tank (320).

[0088] That is, the head (300) for the vacuum cleaner of the present embodiment can basically adopt a squeezing method as in the past. The sewage squeezed by the scraper is received as it falls into the sewage tank (320).

[0089] The suction pipe (400) is connected to the sewage tank (320) and can forcibly suck sewage from the rolling mop (310) and move it to the sewage tank (320). That is, the suction pipe (400) can forcibly suck sewage through the vacuum pressure provided from the above-described pump (330) and discharge it into the sewage tank (320).

[0090] Accordingly, the head (300) for the vacuum cleaner of the present embodiment can more actively remove wastewater by forcibly sucking it in, in addition to squeezing out wastewater using a scraper.

[0091] The suction pipe (400) may be positioned in the sewage tank (320) adjacent to the above-described “A” area and may have an appropriate length that can be accommodated in the sewage tank (320).

[0092] A suction port (410) may be located at one end of the suction pipe (400), and an exhaust port (420) may be located at the other end.

[0093] Here, the suction port (410) is a portion through which wastewater is sucked, and the suction port (410) may be positioned parallel to the upper portion of the wastewater tank (320) or at a certain height higher from the upper portion. The position of the suction port (410) may be adjusted in consideration of the distance from the rolling mop (310).

[0094] The discharge port (420) is a portion through which wastewater is discharged, and the discharge port (420) may be located inside the sewage tank (320). For example, the cross-sectional shapes of the suction port (410) and the discharge port (420) may have various shapes, such as circular, oval, triangular, and square.

[0095] At this time, the suction pipe (400) can be installed in the sewage tank (320) so that the positions of the suction port (410) and the discharge port (420) have a U shape.

[0096] Here, it is preferable that the discharge port (420) be located at a lower height (h) than the suction port (410). This is because if the discharge port (420) is located higher than the suction port (410), the wastewater may flow back into the suction port (410).

[0097] Sewage that flows in through the suction port (410) of the suction pipe (400) including the above-described configuration can be discharged along the pipe to the discharge port (420) and then received in the sewage tank (320).

[0098] For convenience of explanation, the suction pipe (400) is illustrated as a single small pipe.

[0099] However, the suction pipe (400) may be implemented in a slot shape in which the suction port (410) and the discharge port (420) are formed on one side of the road. In addition, the suction pipe (400) may be arranged in multiple pieces at a set interval, and may be modified into an assembly in the form of a baffle.

[0100] According to the cleaning head of this embodiment of the present invention and the cleaner having the same, the problem of moisture remaining on the floor during or after the cleaning process can be improved because the wastewater can be actively removed from the rolling mop (310) through the suction pipe (400) and stored in the wastewater tank (320).

[0101] Meanwhile, the cleaning head (300) of the embodiment may further include a water level detection unit (500) installed in the sewage tank (320) to detect sewage overflow.

[0102] The water level detection unit (500) can measure the water level of sewage and detect when sewage overflows from the sewage tank (320). The water level detection unit (500) can be implemented with various types of sensors, such as an ultrasonic sensor, a pressure sensor, or a laser sensor.

[0103] For example, the water level detection unit (500) may include an electrode sensor.

[0104] An electrode sensor is a sensor that uses electrodes to measure the water level of a sewage tank (320). The electrode sensor operates on the principle of detecting and measuring changes in electrical signals as the electrode comes into contact with liquid.

[0105] For example, the electrodes of the electrode sensor can measure the water level by vertically arranging multiple electrodes in a wastewater tank (320) and depending on the height at which each electrode comes into contact with the liquid. In other words, when a specific electrode comes into contact with the liquid, the electric signal of that electrode changes, and the water level can be determined through this.

[0106] In this embodiment, the electrode sensor may be installed parallel to the height of the discharge port (420) of the suction pipe (400) described above. If the sewage tank (320) is gradually filled with sewage water and the water is filled to a height higher than the discharge port (420), the sewage water may flow backward along the suction pipe (400) and be discharged to the suction port (410).

[0107] Therefore, it is preferable that the electrode sensor be installed at a height where sewage does not flow back, i.e., parallel to the height of the discharge port (420) of the suction pipe (400). Accordingly, when the cleaning head (300) is placed on the ground, the height of the electrode sensor from the ground and the height of the discharge port (420) from the ground may be the same.

[0108] When the electrode sensor detects sewage at the height of the discharge port (420) of the suction pipe (400), it means that the water level in the sewage tank (320) has reached the full level and there is a possibility of overflow. When the electrode sensor detects contact with sewage, it can transmit a signal to the control unit (600) described below.

[0109]

[0110] Meanwhile, FIG. 5 illustrates a drawing for explaining a control configuration of a head for a vacuum cleaner according to one embodiment of the present invention.

[0111] The head unit (300) according to an embodiment of the present invention may further include a control unit (600). The control unit (600) may be placed within the housing (301). Alternatively, the control unit (600) may be provided integrated with the control unit provided in the main body unit (100). In this case, the control unit (600) may be placed within the housing of the main body unit (100).

[0112] Although not shown, the control unit (600) may include a memory. Pre-set information may be stored in the memory.

[0113] Although not shown, the control unit (600) can receive a control signal input through the main body (100).

[0114] The control unit (600) can control the components included in the head unit (300).

[0115] The control unit (600) can be signal-connected to the motor of the rolling mob (310). For example, the control unit (600) can be electrically connected to the motor of the rolling mob (310) and can transmit and receive electrical signals. Accordingly, the control unit (600) can control whether the rolling mob (310) rotates and the rotation speed.

[0116] The control unit (600) can be signal-connected to the pump (330). Accordingly, the control unit (600) can operate or de-operate the pump (330). In addition, the control unit (600) can control the amount of purified water discharged from the pump (330).

[0117] The control unit (600) can be signal-connected to the water level detection unit (500). The control unit (600) can receive a signal from the water level detection unit (500) when the sewage tank (320) is filled with sewage above a preset height.

[0118]

[0119] If the control unit (600) determines through the water level detection unit (500) that there is a risk of sewage stored in the sewage tank (320) overflowing, it can warn the user by guiding with a sound, LED flashing, voice, etc. That is, although not shown, the control unit (600) can notify the user that there is a risk of sewage tank (320) overflowing through a speaker, light source, display, etc. provided in the main body (100). Alternatively, the control unit (600) can notify the user that there is a risk of sewage tank (320) overflowing through a speaker, light source, display, etc. provided in the head unit (300).

[0120] Additionally, the control unit (600) can temporarily stop the operation of the vacuum cleaner by cutting off the power applied to the motor (not shown) to stop the operation of the rolling mop (310).

[0121] Additionally, according to an embodiment, the control unit (600) can cut off the power applied to the pump (330) to cut off the supply of fresh water discharged from the pump (330) to the rolling mop (310). This can block the fresh water from flowing on the floor surface.

[0122] In this way, according to the vacuum cleaner head of the present invention and the vacuum cleaner having the same, the problem of the sewage tank overflowing and sewage leaking out can be prevented.

[0123] In addition, according to the vacuum cleaner head of the present invention and the vacuum cleaner having the same, the problem of moisture remaining on the floor during or after the cleaning process can be improved because moisture is actively removed from the rolling mop and stored in a waste tank.

[0124]

[0125] Above, the present invention has been described in detail through specific examples, but this is for the purpose of specifically explaining the present invention, and the present invention is not limited thereto, and it is clear that the present invention can be modified or improved by a person having ordinary knowledge in the relevant field within the technical spirit of the present invention.
