Description

vacuum cleaner {CLEANER}

The present invention relates to a cleaner, and more particularly, to a cleaner in which a cleaning module for discharging water or steam to a rag to suck or wipe dust or foreign matter in an area to be cleaned is detachable.

A vacuum cleaner is a device that performs cleaning by sucking or wiping dust or foreign matter in an area to be cleaned.

Such a vacuum cleaner may be divided into a manual cleaner in which a user directly moves the cleaner to perform cleaning, and an automatic cleaner in which the user performs cleaning while driving by themselves.

In addition, the manual cleaner may be classified into a canister-type cleaner, an upright-type cleaner, a handy-type cleaner, a stick-type cleaner, and the like, depending on the shape of the cleaner.

Among them, the cordless vacuum cleaner has advantages in portability and cleaning range because it can be cleaned while moving freely without being supplied with electric current through a wire, including a rechargeable battery. Cordless vacuum cleaners include handheld vacuum cleaners and stick cleaners.

The Hand Vacuum Cleaner maximizes portability, and since it is light in weight but short in length, there may be restrictions on the cleaning area while sitting. Therefore, it is used to clean localized places such as on a desk or sofa, or in a car.

The stick vacuum cleaner can be used while standing, so you can clean without bending your back. Therefore, it is advantageous for cleaning while moving a large area. If a hand-held vacuum cleaner cleans a narrow space, the stick-type vacuum cleaner can clean a wider space than that, and can clean a high place that cannot be reached by hand. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.

There are two main types of floor cleaning: dry cleaning and wet cleaning. Dry cleaning is a method of cleaning by sweeping or sucking dust, and a conventional vacuum cleaner corresponds to this. Wet cleaning is a method of cleaning by wiping off dust with a wet cloth. In addition, there is a method of sterilizing and cleaning by generating and spraying high-temperature steam during wet cleaning.

Conventionally, a dry-type cleaner was used for dry cleaning, and a wet-only cleaner was used for wet cleaning. However, there was the inconvenience of having to purchase two types of vacuum cleaners in order to clean various types of floors. In order to solve the above problems, one main body, a dry cleaning module and a wet cleaning module are provided, and for dry cleaning, the dry cleaning module is mounted on the main body, and for wet cleaning, the wet cleaning module is mounted on the main body. method was studied.

The wet cleaning module includes a bucket for storing water, a heater for heating water to generate steam, and a mop for wiping the floor by receiving water or steam. Each of the above parts is preferably configured as one assembly in order to facilitate replacement. For example, when a water tank or a heater is disposed on the main body, there is a problem that cleaning becomes inconvenient due to unnecessary parts when the dry cleaning module is mounted on the main body. It is preferable that the heater is disposed in the wet cleaning module rather than the main body.

Korea Registered Utility Model KR0489070Y1 discloses a wet mop cleaner in which a main battery is provided in a cleaning module and an auxiliary battery is detachably coupled to an extension tube.

However, since the wet mop vacuum cleaner cannot inhale dust and uses most of the power to rotate the mop, combining the auxiliary battery simply increases the use time of the cleaner.

In addition, in the vacuum cleaner that rotates the mop to wipe the floor as described above, when the foreign material is pressed to the floor, the foreign material may still remain even if the floor is cleaned by rotating the mop in which the water has been absorbed.

In addition, when microorganisms are propagated on the floor, there is a limitation in that the microorganisms cannot be completely sterilized even if the floor is wiped by rotating the mop that has absorbed water.

In order to solve this, a method of heating the water supplied to the mop can be considered, but when a heater that uses a large amount of power to heat water is additionally mounted to the cleaning module, it is necessary to supply a large power to the cleaning module there is

The water pump 333 may provide a flow force of water. The water pump 333 may include a first connection port to which the water inlet pipe 332 is connected, and a second connection port to which the guide pipe 334 is connected. In this case, based on the water pump 333 , the first connection port may be an inlet, and the second connection port may be an outlet.

The water supply pipe 335 may connect the connector and the water inlet 336b of the steam generator 336 . For example, the water supply pipe 335 may be a pair of pipes branched from the connector.

Accordingly, after the water supplied to the water inlet pipe 332 is introduced into the water pump 333 , it flows into the guide pipe 334 . The water flowing to the guide pipe 334 flows to the water supply pipe 335 by the connector. Then, the water flowing through the water supply pipe 335 is supplied to the steam generator 336 .

The steam generator 336 is a device for heating water. The steam generator 336 is disposed inside the module housing 310 . Specifically, the steam generator 336 is installed on the upper surface of the lower housing 311 .

The steam generator 336 includes a heating chamber 336a, a water inlet 336b and a water outlet 336c.

A flow path through which water introduced from the water tank 320 can flow is formed in the heating chamber 336a. The heating chamber 336a may receive power from the battery 190 and/or the auxiliary battery 500 to heat water. The heating chamber 336a may adjust the temperature of water according to the user's control.

Meanwhile, in the present invention, the steam generator 336 is inclined. Specifically, the heating chamber 336a is disposed to be inclined at a predetermined angle with respect to the ground (floor surface).

For example, the rear end of the heating chamber 336a is disposed above the front end of the heating chamber 336a. That is, the steam generator 336 has a backward-upward slope. Accordingly, the water may be heated while flowing from the upper rear to the lower front of the steam generator 336 .

Meanwhile, the water inlet 336b may be disposed at the rear end of the heating chamber 336a, and the water outlet 336c may be disposed at the front end of the heating chamber 336a. That is, based on the state in which the lower housing 311 is placed on the floor (ground), the water inlet 336b may be disposed farther from the floor (ground) than the water outlet 336c. Accordingly, the water is heated while the water flows from the top to the bottom due to gravity, and even if the water rises through a phase change into water vapor, it can be discharged to the water outlet 336c by the flow force of the water.

The diffuser 337 is configured to discharge the water from the water tank 320 to the mop 350 .

The diffuser 337 may be accommodated in a space formed inside the module housing 310 . The diffuser 337 may be connected to the steam generator 336 to discharge moisture heated by the steam generator 336 to the mop 350 .

For example, the diffuser 337 may be formed in a ring shape, and a plurality of nozzles may be provided along the circumferential direction at predetermined intervals. At this time, the mop driving motor 370 may be disposed inside the annular diffuser. With this configuration, the diffuser 337 can quickly supply moisture to the entire mop 350 in the form of a disk. In addition, since the thickness of the tube can be reduced compared to other types of diffusers that flow the same amount of moisture, it is advantageous for securing space in the vertical direction. In addition, by arranging the mop drive motor 370 in the center of the annular diffuser 337, it is possible to increase the space utilization. As a result, it is possible to secure a space for the auxiliary battery 500 to be inserted into the module housing 310 .

As another example, the diffuser 337 may be formed in an arc shape, and a plurality of nozzles may be provided at predetermined intervals. With this configuration, the diffuser 337 can stably supply moisture to the rag 350 in the form of a disk.

Water sprayed from the diffuser 337 is supplied to the mop 350 after passing through the water passage hole formed in the rotary cleaning unit 340 . The mop 350 is rotated while absorbing the water supplied through the diffuser 337 to wipe the floor.

The distance between the rotation center of the first rotation cleaning unit 341 and the rotation center of the second rotation cleaning unit 342 may be greater than the diameter of the mop 350 . This is to reduce the friction between the first mop 351 and the second mop 352 as they interfere with each other in the course of rotation, and to prevent the area that can be cleaned by the interfering portion from being reduced.

The mop 350 may wipe the floor surface by rotational motion.

The mop 350 may include a first mop 351 coupled to the first rotary cleaning unit 341 and a second mop 352 coupled to the second rotary cleaning unit 342 . Therefore, when the first rotation cleaning unit 341 is rotated by receiving the power of the first mop driving motor 371, the first mop 351 is also rotated, and the second rotating cleaning unit 342 is the second mop driving motor ( When the power of 372 is received and rotated, the second mop 352 may also be rotated.
