Description

Sweeper

The present invention relates to a sweeping machine, and more particularly to a portable vacuum cleaner which can attach and detach a sweeping module.

In general, a sweeper is a household appliance that sucks tiny garbage or dust by using electricity to suck air, and loads the garbage or dust into a dust box included in the cleaner product. Such sweepers are commonly referred to as vacuum cleaners.

This cleaning machine can be divided into a manual cleaning machine and an automatic cleaning machine. The former cleans by being directly moved by the user, and the latter cleans while moving by itself. Hand sweepers can be divided into canister vacuum cleaners, upright vacuum cleaners, hand-held vacuum cleaners and stick vacuum cleaners according to their shape.

In the past, canister vacuum cleaners were widely used as household sweepers. However, recently, hand-held vacuum cleaners and stick-type vacuum cleaners, which include a dust box integrally formed with a cleaner main body and provide improved usability, tend to be widely used.

In the case of a canister vacuum cleaner, the main body and its suction opening are connected by a rubber hose or pipe. In some cases, the vacuum cleaner can be used with a brush inserted into the suction opening.

Handheld vacuum cleaners are designed for maximum portability and thus are lightweight and short in length. Therefore, the cleaning area of the vacuum cleaner may be limited. Therefore, hand-held vacuum cleaners are used for cleaning localized places, such as on a table or sofa, inside a vehicle.

Stick vacuum cleaners allow users to use them in a standing position, so they can clean without bending forward at the waist. Therefore, it is advantageous for cleaning when moving over a wide range. Where hand-held vacuums can clean tight spaces, stick vacuums can clean wider spaces than narrow spaces and can clean high, hard-to-reach places. Recently, stick vacuum cleaners are provided in the form of modules, so that the type of vacuum cleaner can be actively changed according to different objects.

The method of cleaning the ground is mainly divided into dry cleaning and wet cleaning. Dry cleaning is carried out by sweeping or suctioning dust, and traditional vacuum cleaners are dry cleaning. Wet cleaning is carried out by mopping the dust with a mop. In addition, there is a method of disinfecting and cleaning by generating and spraying high-temperature steam during wet cleaning.

Recently, due to the application of various materials in construction, cleaning methods have also been diversified. In the past, since the floor was mainly composed of wooden materials, wet cleaning was not possible and only dry cleaning was possible. However, in recent years, floors are composed of various materials such as steel plates or marble, which can be wet cleaned.

In the past, dry sweepers have been used for dry sweeping and wet sweepers have been used for wet sweeping. However, in order to clean various grounds, these two types of sweepers must be purchased, which is quite inconvenient. In order to solve the above problems, the present invention has studied a method in which a main body, a dry cleaning module, and a wet cleaning module are provided, the dry cleaning module is installed on the main body for dry cleaning, and the wet cleaning module is installed on the body for wet cleaning.

The wet cleaning module includes: a water storage tank for storing water; a heater for heating water to generate steam; and a mop for wiping the ground by receiving water or steam. Preferably, the components are configured as a single assembly to facilitate replacement of components. For example, in the case that the cleaning machine includes a water storage tank or a heater provided on the main body, several types of cleaning modules are installed on the main body, and cleaning is inconvenient due to unnecessary parts. Therefore, in view of the convenience of cleaning and module replacement and space utilization, it is ideal that the water storage tank or the heater should be arranged on the wet cleaning module instead of on the main body.

Korean Patent Application Publication No. 10-2009-0043379 is proposed as prior art document 1. This prior art document 1 relates to a heater device and a sweeper having the heater device. The sweeper according to the prior art document 1 includes a heater device including a heating housing, which receives water from a water supply tank and generates steam.

According to the prior art document 1, the water storage tank is installed to be attachable to and detachable from the main body, instead of the nozzle assembly. In addition, the heater unit for generating steam is also installed in the main body instead of the nozzle assembly. According to the prior art document 1, in order to design the nozzle assembly into a smaller size and obtain a sufficient storage capacity of the water storage tub, the water storage tub and the heater device are installed in the main body instead of the nozzle assembly.

In the case of the prior art document 1, no independent vent is provided. Therefore, the thermal energy of the heater remains inside the housing and does not radiate outward. When heat energy reaches the pump, the pump may overheat and be damaged. Another problem is that the thermal energy may also damage other delicate components installed in the housing.

Furthermore, according to Prior Art Document 1, since the water storage tank is installed in the main body, the center of gravity of the sweeper is high, making it difficult to operate the sweeper. Also, due to the long distance between the heater and the mop, heat energy is lost as the steam travels to the mop, and this lost heat can damage delicate electronics.

Korean Patent No. 10-1342567 is proposed as prior art document 2. This prior art document 2 relates to a steam sweeper. According to the prior art document 2, the steam generator has a simple structure and can improve steam generation efficiency. Also, the steam-supplied mop rotates on both left and right sides, thus improving cleaning efficiency.

In prior art document 2, a plurality of vents are formed on the rear surface of the casing. Vents are configured to cool heat from the heater. However, as the heater becomes too cold, there may be a problem that the thermal efficiency of the heater decreases and the air that absorbs heat energy from the heater rises to overheat the pump.

In addition, similar to the prior art document 1, the water storage tank and the heater of the prior art document 2 are installed in the main body of the cleaning machine instead of the cleaning module. Therefore, Prior Art Document 2 has the same problems as Prior Art Document 1.

Korean Patent No. 10-2172613 is proposed as prior art document 3. This prior art document 3 relates to a steam mop cleaner. According to the prior technical document 3, the brushes around the water storage bucket rotate to guide the dust to the central suction port, thereby keeping the steam mop clean and enabling the steam mop to be cleaned.

However, like the prior art document 1, according to the prior art document 3, since the independent vent is not formed in the case, the heat energy of the heater remains in the case, and the heat energy may damage other precision parts installed in the case.

In addition, when the height of the water storage tank is lowered to lower the height of the cleaning module, there is also a problem that the storage capacity of the water storage tank is reduced.

A main battery can be removably coupled to the sweeper.

The main battery can supply power to the cleaning module 100 . Alternatively, the cleaning module 100 may receive power from a secondary battery.

The extension pipe 200 guides the air sucked by the cleaning module 100 to the main body (not shown).

One end of the extension pipe 200 communicates with the cleaning module 100 , and the other end communicates with the main body. Specifically, the rear end of the extension pipe 200 is connected to the main body, and the front end of the extension pipe 200 is connected to the cleaning module housing 110 .

The extension pipe 200 is formed as a long cylinder.

The rolling axis (X) is formed along the longitudinal direction of the extension tube 200 . The rolling axis (X) is an imaginary line extending along the front-to-back direction, and the cleaning module 100 can roll around the rolling axis (X).

Referring to FIG. 3 , the rolling axis (X) is an imaginary line extending in the front-rear direction while passing through the center of the cleaning module 100 when viewed from the top.

Referring to FIG. 9 , the rolling axis (X) is an imaginary line extending from the front end of the extension pipe 200 along the central axis of the dust passage 180 when viewed from the right side.

The cleaning machine includes a cleaning module 100 . The cleaning module 100 is a component for cleaning a cleaning area by sucking external air or generating steam.

The mop 161 is connected to the steam outlet 132 of the heater 130 and receives steam from the heater 130 . Referring to FIG. 9 , the mop 161 releases steam downward to sweep the cleaning area at high temperature. The steam released from the mop 161 is blocked by the shielding member 170 and does not flow into the suction port 181 .

Referring to FIG. 2 , a pair of mopping cloths 161 may be disposed on left and right sides of the cleaning module 100 .

The mop 161 is provided with a rotation axis arranged perpendicular to the ground. The mop 161 rotates around the axis of rotation and scrubs and cleans the ground.

Here, two or more mopping cloths 161 can be rotated in different directions, so that it is easier for the user to operate. Taking FIG. 2 as an example, the right mop 161 can rotate clockwise (CW), and the left mop 161 can rotate counterclockwise (CCW). Therefore, the pair of mops 161 can push the cleaning module 100 forward through frictional force, and the user can move the cleaning machine forward more easily.

The sub battery 300 may be connected in series with the main battery. Therefore, when the electric energy stored in the secondary battery 300 is insufficient, the secondary battery 300 is connected in series with the main battery to supply sufficient voltage power to the cleaning module 100 .

The sub battery 300 may be connected in parallel with the main battery. Therefore, the time to supply power to the cleaning module 100 can be improved.

The sub battery 300 may be disposed at the front end of the extension tube 200 . Alternatively, the sub battery 300 may be disposed on a lower portion of the extension pipe 200 . With this arrangement, the center of gravity of the sweeper assembly, in which the sweeper module 100 and the sub-battery 300 are coupled, is set at its lower portion, so the sweeper can be easily turned.

The sub battery 300 may be disposed on an upper portion of the extension pipe 200 . Specifically, the sub battery 300 may be disposed above an imaginary line extending from the center of the extension pipe 200 in the longitudinal direction of the extension pipe 200 .

Referring to FIG. 1 , the cleaning module case 110 is connected to the front end of the extension pipe 200 , and the rear end of the extension pipe 200 is connected to the main body. Therefore, the cleaning module case 110 is indirectly connected to the main body through the extension pipe 200 . Different from this, although not shown, the cleaning module case 110 may be directly and indirectly connected to the main body.

The above meaning of "connection" can have various interpretations. For example, the air flow path is connected to the main body, so the air containing dust can flow to the main body through the cleaning module case 110 . Alternatively, the cleaning module housing 110 may be electrically connected to the main body, and current may flow from a main battery disposed in the main body to the cleaning module housing 110 .

The water storage bucket 120 is installed on the top surface of the cleaning module case 110 .

An air inlet 1111 is formed on the front surface of the cleaning module case 110 so that external air can be introduced into the cleaning module case 110 .

The light emitting module 150 can be disposed under the front surface of the cleaning module housing 110 , and can emit light to the ground in front of the cleaning module 100 .

Specifically, the lower partition wall 1112 is disposed outside the heater 130 and disposed inside the mopping motor 162 when viewed from the top. With this arrangement, the lower partition wall 1112 blocks heat energy radiated from the heater 130 from reaching the mopping motor 162 , thereby preventing the mopping motor 162 from being damaged.

An upper portion of the lower partition wall 1112 faces a lower portion of the upper partition wall 1122 and isolates an inner space in which the heater 130 is disposed from an outer space in which other components are disposed. With this arrangement, heat energy radiated from the heater 130 remains around the heater 130, and the thermal efficiency of the heater 130 can be improved through the effect of heat insulation.

An air flow path is formed outside the lower partition wall 1112 . Specifically, the air introduced into the cleaning module housing 110 through the air inlet 1111 flows outside the lower partition wall 1112 and then flows toward the air outlet 1121 .

A shielding member insertion groove 1113 is formed on the bottom surface of the lower case 111 . The shielding member 170 is inserted into the shielding member insertion groove 1113 and installed.

With this arrangement, thermal energy is transferred in the upper case 112 by thermal conduction, but thermal energy is transferred between the heater 130 and the upper case 112 by thermal convection. Therefore, the type of heat transfer is switched, thereby reducing the efficiency of heat transfer.

An upper partition wall 1122 is formed in the upper case 112 . The upper partition wall 1122 is disposed on the bottom surface of the upper case 112 and extends downward toward the heater 130 .

Specifically, the upper partition wall 1122 is disposed outside the heater 130 and disposed inside the mopping motor 162 when viewed from the top. With this arrangement, the upper partition wall 1122 blocks heat energy radiated from the heater 130 from reaching the mopping motor 162 , thereby preventing the mopping motor 162 from being damaged.

A lower portion of the upper partition wall 1122 faces an upper portion of the lower partition wall 1112 and isolates an inner space in which the heater 130 is disposed from an outer space in which other components are disposed. With this arrangement, heat energy radiated from the heater 130 remains around the heater 130, and the thermal efficiency of the heater 130 can be improved through the effect of heat insulation.

Referring to FIG. 11 , an air flow path is formed outside the upper partition wall 1122 . Specifically, the air introduced into the cleaning module housing 110 through the air inlet 1111 flows outside the upper partition wall 1122 and then flows toward the air outlet 1121 .

When the release button 1123 is operated, the release button 1123 is pressed down, thereby releasing the fastening of the coupling hook 125 and attachably detaching the water storage bucket 120 .

The release button 1123 may be disposed on the extension pipe placement part 127 of the water storage bucket 120 .

The upper case 112 has a thermal barrier coating surface 1124 formed on its inner surface facing the heater 130 . The thermal barrier coating surface 1124 blocks thermal energy radiated from the heater 130 from being transferred to the upper housing 112 .

The thermal barrier coating surface 1124 is disposed in a region partitioned by the upper partition wall 1122 among the inner surface of the upper case 112 . Accordingly, the thermal barrier coating surface 1124 blocks thermal energy radiated upward from the heater 130 from being transferred to the upper housing 112 .

The shielding member 170 shields a front space where the suction port 181 is disposed and a rear space where the mop 161 is disposed, thereby blocking steam emitted from the mop 161 from diffusing into the suction port 181 .

The shielding member 170 is disposed on the cleaning module housing 110 and disposed between the suction port 181 and the mop 161 .

Without the shielding member 170 , thermal energy or steam radiated from the mop 161 may spread forward and be introduced into the suction port 181 . The steam introduced through the suction port 181 reaches the main body of the sweeper through the dust passage 180 and the extension pipe 200 . During this process, the dust channel 180, the extension pipe 200 and the main body of the sweeper all overheat. Therefore, if a user touches these components, the user may be burned and may damage other electronic devices located near these components. In order to solve this problem, the cleaning machine according to the present invention includes a shielding member 170 so as to block heat energy or steam radiated from the mop 161 from flowing into the suction port 181 .

Therefore, when the cleaning module 100 moves forward, dust remaining in the cleaning area may be collected in the central portion 171 along the first extension 172 and sucked into the suction port 181, thereby improving cleaning performance.

The second extension 173 is provided in front of the auxiliary wheel. With this arrangement, the dust remaining in the cleaning area can be prevented from being stuck in the auxiliary wheels and causing the auxiliary wheels to lose their function.

Specifically, the air inlet 1111 may be disposed below the heater 130 , and the air outlet 1121 may be disposed above the heater 130 . With this arrangement, the air flowing in the cleaning module 100 is close to the heater 130 , so that the air can obtain heat energy from the heater 130 and release the heat energy to the outside of the cleaning module 100 . In addition, it can also prevent the heat energy emitted by the heater 130 from damaging the electronic equipment.

Referring to FIG. 11 , the air outlet 1121 may be disposed more outside than the air inlet 1111 . With this arrangement, the flow direction of the air introduced from the air inlet 1111 to the rear is changed, and thus, the air is laterally discharged from the air outlet 1121 . Therefore, in the internal space of the cleaning module 100 , vortices are generated in the air flow, thereby having the effect of absorbing heat energy remaining in the components disposed at the corners.

The lower partition wall 1112 or the upper partition wall 1122 is disposed around the heater 130 and isolates an internal space in which the heater 130 is disposed from an external space in which other components are disposed. Therefore, it is possible to prevent the heat energy emitted from the heater 130 from radiating outward. In addition, the heat energy dissipated from the heater 130 will remain around the heater 130, and the thermal efficiency of the heater 130 can be improved through the heat insulation effect.

The mop motor 162 or the printed circuit board 190 is disposed on a flow path of air introduced into the air inlet 1111 . With this arrangement, the mop motor 162 or the printed circuit board 190 can be sufficiently cooled and thus not damaged by the heat energy emitted by the heater 130 .

The shielding member 170 is disposed on the cleaning module housing 110 and disposed between the suction port 181 and the mop 161 . The shielding member 170 blocks heat or steam emitted from the mop 161 from flowing into the suction port 181, so that the steam flows through the extension pipe 200 through the dust channel 180, thereby preventing heat damage to peripheral components and the risk of burns to the user.
