Description

Dust collector

Technical Field

The present invention relates to a vacuum cleaner, and more particularly, to a portable vacuum cleaner in which a cleaning module is detachable.

Background

In general, a vacuum cleaner is a home appliance that sucks small garbage or dust in a manner of sucking air by using electricity and fills it into a dust bin in a product, and is generally called a vacuum cleaner.

Such a cleaner may be classified into a manual cleaner in which a user directly moves the cleaner to perform cleaning, and an automatic cleaner in which the user automatically travels to perform cleaning. The manual vacuum cleaner may be classified into a canister-type (canister-type) vacuum cleaner, an upright-type (upright) vacuum cleaner, a hand-held vacuum cleaner, a stick-type (stick-type) vacuum cleaner, etc., according to the type of the vacuum cleaner.

In recent years, a dust collection tub and a cleaner main body are integrated, and a hand cleaner and a stick cleaner which improve the convenience of use are increasingly used.

In the cylinder cleaner, a main body and a suction port are connected by a rubber hose (hose) or a pipe (pipe), and a brush may be mounted to the suction port according to circumstances.

The hand-held cleaner (Hand Vacuum Cleaner) is a cleaner that maximizes portability, but has a limited cleaning area because of its short length and the need to be squatted for cleaning. Thus, it is used for cleaning local places such as desks, sofas or in automobiles.

The stick-type cleaner can be used standing, so that cleaning can be performed without bending down. Thus, the cleaning device can be moved in a wide area and cleaned. Compared with a handheld dust collector for cleaning a narrow space, the stick dust collector can clean a wider space and can clean a high place which cannot be reached by an adversary. In recent years, stick cleaners have been provided in a module form to actively change the type of the cleaner for various objects and use the same.

The method of cleaning the floor is broadly classified into dry cleaning and wet cleaning. Dry cleaning is a cleaning method by sweeping or sucking dust, and the conventional vacuum cleaner corresponds to this type. Wet cleaning is a method of cleaning dust by wiping the dust with a wet wipe. In addition, there is a method of generating and spraying high-temperature steam to perform sterilization and cleaning in wet cleaning.

Recently, as various materials are used in buildings, cleaning modes have also become diversified. Conventionally, a floor is mainly made of a wooden material, and wet cleaning is not possible, but only dry cleaning is possible. However, recently, the floor is made of various materials such as steel plates and marble, so that wet cleaning is also possible.

Conventionally, a dry-type dedicated cleaner is used for dry cleaning, and a wet-type dedicated cleaner is used for wet cleaning. However, it is inconvenient that two types of cleaners must be purchased in order to clean various types of floors. In order to solve the above-described problems, a method has been studied which includes a single main body, a dry cleaning module and a wet cleaning module, wherein the dry cleaning module is mounted on the main body for dry cleaning and the wet cleaning module is mounted on the main body for wet cleaning.

The wet cleaning module includes a water tub storing water, a heater generating steam by heating the water, a cloth wiping a floor by receiving the water or the steam, and the like. For ease of replacement, the individual components described above are preferably formed from an assembly. For example, in the case where the water tub or the heater is disposed in the main body, when the dry cleaning module is attached to the main body, there is a problem in that cleaning is inconvenient due to unnecessary components, and therefore, in view of ease of cleaning or ease of module replacement or space utilization, the water tub or the heater is preferably disposed in the wet cleaning module instead of the main body.

Prior art 1 is an invention related to a heater device and a dust collector including the heater device. The cleaner of prior art 1 includes a heater device having a heating housing that receives water from a water supply tank and generates steam.

According to prior art 1, the water tub is detachably provided to the main body instead of the nozzle assembly. In addition, the heater device that generates the steam is also provided to the main body instead of the nozzle assembly. In prior art 1, the water tub and the heater device are provided at the main body instead of the nozzle assembly to design the size of the nozzle assembly smaller and ensure sufficient storage capacity of the water tub.

The housing of prior art 1 has no additional vents. Therefore, the heat of the heater remains inside the casing and is not dissipated to the outside. If the heat is transferred to the pump, there is a risk of the pump overheating and failing. Alternatively, there is a problem in that the heat may damage other precision parts provided inside the case.

In addition, in the prior art 1, the water tub is provided at the main body, and thus there is a problem in that the center of gravity is high and the operation is difficult. In addition, the distance between the heater and the wiper is long, and the steam generates heat loss during the flowing to the wiper, so that there is also a problem that the lost heat damages sensitive electronic equipment.

Prior art 2 relates to the invention of a steam cleaner. The prior art 2 can improve the steam generation efficiency while simplifying the structure of the steam generation part, and improve the cleaning efficiency by rotating the cloth receiving the steam on the left and right sides.

In prior art 2, a plurality of vents are formed in the back surface of a case. However, the vent is configured to cool the heat of the heater, and as the heater is supercooled, there is a possibility that the heat efficiency of the heater is lowered, and the air that absorbs the heat of the heater rises, and there is a problem that the pump is overheated.

In addition, as in the case of the prior art 1, the water tub and the heater of the prior art 2 are also provided in the cleaner main body instead of the cleaning module, and thus have the same problems as the prior art 1.

Prior art 3 is an invention relating to a steam wet wipe vacuum cleaner. In prior art 3, the cleaning of the steam wet wipe can be performed while keeping the steam wet wipe clean by rotating the brush at the periphery of the water tub to guide dust to the suction port at the center.

However, as in prior art 1, since no special vent is formed in the case of prior art 3, there is a problem in that heat of the heater remains inside the case, and the heat may damage other precision components provided inside the case.

In addition, in order to reduce the height of the cleaning module, the height of the water tub is also reduced, so that there is a problem in that the storage capacity of the water tub is reduced.

Detailed Description

The advantages, features and methods for accomplishing the same may be understood more readily by reference to the accompanying drawings and the examples described in detail below. However, the present invention is not limited to the embodiments disclosed below, but may be embodied in various forms, and the present embodiment is only for more complete disclosure of the present invention, so that a person skilled in the art to which the present invention pertains is more complete in prompting the scope of the present invention, and the present invention is limited only by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

The present invention will be described below with reference to the accompanying drawings for illustrating a cleaner by way of examples of the present invention.

The cleaner is a cleaning device manually operated by a user. For example, the cleaner may be a hand-held cleaner or a stick cleaner.

The cleaner may include a main body (not shown). The main body is a component in which a suction motor (not shown) is provided to supply suction force to the cleaning module 100.

The body may be connected with the extension tube 200. The main body may be connected to the cleaning module 100 by means of an extension tube 200. The main body may generate suction force using the suction motor, and may provide suction force to the cleaning module 100 through the extension pipe 200. External dust may flow into the main body via the cleaning module 100 and the extension pipe 200.

The main body forms an outer shape and accommodates a main constituent element therein. The main body may be provided with a dust collection tub, a dust separation part, a suction motor, a filter, a handle, an operation part, and a main battery.

The dust collection tub (not shown) is a constituent element for storing dust. The dust collection tub communicates with the dust separation part, and may store dust separated in the dust separation part.

The dust separating part (not shown) communicates with the extension pipe 200. The dust separating part may separate dust sucked into the inside through the extension pipe 200 from air.

The dust separating part may be in communication with the dust collection tub. In more detail, the dust separating part may be disposed inside the dust tub. Accordingly, the dust separated in the dust separating part is collected to the dust tub, and the air is discharged to the outside of the dust separating part.

The dust separating part may be a cyclone capable of separating dust using cyclone flow.

The suction motor (not shown) is a component for generating suction force of the suction air. The suction motor is accommodated in the main body. The suction motor generates suction by rotating.

The filter (not shown) is a component for filtering foreign matters contained in the flowing air. The filter may comprise a pre-filter or a HEPA filter.

The pre-filter is a filter disposed at the most upstream of the plurality of filters, and is formed in a net shape, and physically filters larger dust in a first stage. The prefilter is a component for physically filtering dust larger than the interval between the meshes to extend the life of other filters.

The HEPA filter is a constituent element of filtering fine dust, and is a generic name of High Efficiency Particulate Air (HEPA). Generally, high efficiency particulate air filters utilize electrostatic forces to filter fine dust. The HEPA filter is disposed downstream of the pre-filter.

A body handle (not shown) may be held by a user. The body handle may be formed to resemble a cylinder shape. Alternatively, the body handle 116 may be formed in a curved cylindrical shape.

The operation unit (not shown) is a component for receiving a command from a user. The operation unit may be constituted by a plurality of buttons, and if the user presses the corresponding button, the instruction corresponding thereto is executed. For example, the operation portion may have an operation button and a stop button.

A main battery (not shown) may be disposed in the main body. The main battery is a component that stores electric energy and supplies power to each component of the vacuum cleaner including the suction motor.

The main battery may be detachably coupled to the cleaner.

The main battery may provide power to the cleaning module 100. In contrast, the cleaning module 100 may receive electric power from the sub-battery.

The extension pipe 200 is a component for guiding air sucked from the cleaning module 100 to a 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 case 110.

The extension pipe 200 is formed in an elongated cylindrical shape.

A rotation (Rolling) axis x is formed along the length of the extension pipe 200. The rotation axis x is an imaginary line extending in the front-rear direction, and the cleaning module 100 can perform a rotational motion about the rotation axis x.

Referring to fig. 3, the rotation axis x is an imaginary line extending forward and backward through the center of the cleaning module 100 when viewed from above.

Referring to fig. 9, the rotation axis x is a virtual line extending from the tip of the extension pipe 200 along the central axis of the dust flow path 180 when viewed from the right side.

The cleaner includes a cleaning module 100. The cleaning module 100 is a component that sucks outside air or generates steam to clean a cleaning area.

The cleaning module 100 is connected to the main body. The cleaning module 100 may be directly connected to the main body, or may be indirectly connected to the main body through the extension pipe 200.

Referring to fig. 1 and 2, the cleaning module 100 includes at least one or more wipes 161. The wiper 161 is a component that contains moisture and wipes the floor.

The wiper 161 is connected to the steam outlet 132 of the heater 130, and receives steam from the heater 130. Referring to fig. 9, the wiper 161 may discharge steam to the lower portion to sweep a sweeping area at a high temperature. The vapor discharged from the wiper 161 is blocked by the shielding member 170 so as not to flow into the suction port 181.

Referring to fig. 2, the cleaning cloth 161 is disposed in a pair on the left and right sides of the cleaning module 160.

The wiper 161 has a rotation axis disposed perpendicular to the floor, and rotates around the rotation axis to wipe and clean the floor.

At this time, two or more of the wipes 161 are rotated in different directions, so that the user can easily operate the cleaning cloth. Taking fig. 2 as an example, the right hand wipe 161 may be rotated clockwise CW and the left hand wipe 161 may be rotated counterclockwise CCW. Accordingly, the pair of cleaning cloths 161 can push the cleaning module 100 forward by friction force, so that the user can more easily advance the cleaner 100.

Fig. 1 is a perspective view of a cleaning module 100 of the present invention. Fig. 2 is a front view of the cleaning module 100 of fig. 1 from the front. Fig. 3 is a top view of the cleaning module 100 of fig. 1, as viewed from above. Fig. 4 is a right side view of the cleaning module 100 of fig. 1 from the right side. Fig. 5 is a bottom view of the cleaning module 100 of fig. 1, as viewed from below.

The cleaning module 100 is connected to the main body. Referring to fig. 1, the cleaning module 100 is connected to the extension pipe 200, and may be indirectly connected to the main body through the extension pipe 200.

The sub-battery 300 is provided to the extension pipe 200. Specifically, the sub-battery 300 may be disposed at the front end of the extension pipe 200. The sub-battery 300 is electrically connected to the cleaning module 100, and supplies power to each component arranged in the cleaning module 100. For example, the secondary battery 300 may supply power to the heater 130, or may supply power to the wipe motor 162.

The sub-battery 300 may be electrically connected with the main battery. Thereby, the sub-battery 300 can receive electric power from the main battery.

The sub-battery 300 may be connected in series with the main battery. In this way, in the case where the electric energy stored in the sub-battery 300 is insufficient, it is possible to supply the cleaning module 100 with electric power of a sufficient voltage by connecting the sub-battery 300 and the main battery in series.

The sub-battery 300 may be connected in parallel with the main battery. This can lengthen the time for supplying power to the cleaning module 100.

The sub-battery 300 may be disposed at the front end of the extension pipe 200. Alternatively, the sub-battery 300 may be disposed at the lower end of the extension pipe 200. With this arrangement, the center of gravity of the cleaner assembly in which the cleaning module 100 and the sub-battery 300 are combined is arranged at the lower portion, and the cleaner can be easily turned.

The sub-battery 300 may be disposed at the upper portion of the extension pipe 200. Specifically, the sub-battery 300 may be disposed at an upper position than a virtual line extending from the center of the extension pipe 200 in the longitudinal direction of the extension pipe 200.

The cleaning module case 110 forms the outer shape of the cleaning module 100, and a space for accommodating other components is formed therein.

The cleaning module case 110 is connected to the main body. 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, so that the cleaning module case 110 is indirectly connected to the main body through the extension pipe 200. In contrast, although not shown, the cleaning module case 110 may be directly connected to the main body.

The meaning of "connected" as described above may be interpreted in a variety of ways. For example, the cleaning module case 110 and the air flow path of the main body are connected to each other, so that air containing dust can flow toward the main body through the cleaning module case 110. Alternatively, the cleaning module case 110 is electrically connected to the main body, and the current may flow from the main battery disposed in the main body to the cleaning module case 110.

A water tub 120 is installed at an upper surface of the cleaning module case 110.

An air inlet 111 is formed at the front surface of the cleaning module case 110 so that external air can flow into the cleaning module case 110.

The light emitting module 150 is disposed at the front lower portion of the cleaning module case 110, and can radiate light to the front floor of the cleaning module 100.

An air discharge port 1121 is formed at a side of the cleaning module case 110 so that air inside the cleaning module case 110 can be discharged to the outside.

The cleaning cloth 161 is disposed on the bottom surface of the cleaning module case 110. The wiper 161 may perform wet cleaning by wiping the cleaning area.

A suction port 181 is disposed on the bottom surface of the cleaning module case 110. The suction port 181 can perform dry cleaning by sucking dust existing on the floor.

A shielding member 170 is disposed on the bottom surface of the cleaning module case 110. The shielding member 170 shields a front space in which the suction port 181 is disposed and a rear space in which the wiper 161 is disposed, thereby blocking diffusion of the vapor discharged from the wiper 161 to the suction port 181.

The cleaning module case 110 may be divided into a lower case 111 and an upper case 112.

The lower housing 111 forms part of the lower face and sides of the cleaning module 100.

A heater 130 is provided on the upper surface of the lower case 111.

An air inlet 111 is formed in the front surface of the lower case 111.

The light emitting module 150 is provided in the lower case 111, and a hole through which light passes is formed in the front surface of the lower case 111. The hole through which the light passes is formed at a lower portion of the air inflow port 111.

A wiper is disposed on the bottom surface of the lower case 111. A groove recessed upward is formed on one side of the bottom surface of the lower case 111 to dispose the wiper.

A suction port 181 is disposed on the bottom surface of the lower case 111. The suction port 181 is disposed in front of the wiper 161.

A plurality of components for driving the cleaning module 100 are provided on the upper surface of the lower case 111.

A lower partition wall 1112 is formed on the upper surface of the lower case 111. The lower partition wall 1112 is disposed at the periphery of the heater 130 to block outward heat dissipation of heat discharged from the heater 130.

The lower partition wall 1112 is formed to protrude upward from the upper surface of the lower case 111.

The lower partition wall 1112 is disposed outside the heater 130. The lower partition wall 1112 is disposed apart from the heater 130 on the outer side of the heater 130.

The lower partition wall 1112 is disposed between the heater 130 and the wiper motor 162. Specifically, the lower heater 1112 is disposed outside the heater 130 and inside the wiper motor 162 when viewed from above. With this configuration, the lower partition wall 1112 blocks heat emitted from the heater 130 from being transferred to the wiper motor 162, preventing the wiper motor 162 from being damaged.

The upper end of the lower partition wall 1112 faces the lower end of the upper partition wall 1122, and separates an internal space in which the heater 130 is disposed and an external space in which other members are disposed. With such a configuration, heat emitted from the heater 130 remains around the heater 130, and the thermal efficiency of the heater 130 can be improved by the heat retaining effect.

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

A shielding member insertion groove 1113 is formed in a lower surface of the lower case 111. The shielding member 170 is inserted into the shielding member insertion groove 1113.

The upper housing 112 forms part of the upper and side faces of the cleaning module 100.

The upper case 112 is coupled to the lower case 111, and is disposed at an upper portion of the heater 130 to be spaced apart from the heater 130, and a water tub 120 is provided at an upper surface of the upper case 112.

An air outlet 1121 is formed in a side surface of the upper case 112.

The upper housing 112 is disposed apart from the heater 130. Heat discharged from the heater 130 is convected to the upper case 112. With such a configuration, in the upper case 112, heat is transferred by heat conduction, but since heat is transferred between the heater 130 and the upper case 112 by heat convection, there is an effect that heat transfer efficiency is lowered as the heat transfer type is converted.

An upper partition wall 1122 is formed in the upper housing 112. The upper partition wall 1122 is disposed on the lower surface of the upper case 112 and extends downward toward the heater 130. The upper partition wall 1122 surrounds at least a portion of the side surface of the heater 130, and thus blocks the lateral convection of heat discharged from the heater 130.

The upper partition wall 1122 is disposed outside the heater 130. The upper partition wall 1122 is disposed apart from the heater 130 on the outer side of the heater 130.

The upper partition wall 1122 is disposed between the heater 130 and the wiper motor 162. Specifically, the upper heater 1122 is disposed outside the heater 130 and inside the wiper motor 162 when viewed from above. With this arrangement, the upper partition wall 1122 blocks heat emitted from the heater 130 from being transferred to the wiper motor 162, preventing the wiper motor 162 from being damaged.

The lower end of the upper partition wall 1122 faces the upper end of the lower partition wall 1112, and separates an internal space in which the heater 130 is disposed and an external space in which other members are disposed. With such a configuration, heat emitted from the heater 130 remains around the heater 130, and the thermal efficiency of the heater 130 can be improved by the heat retaining effect.

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

A release button 1123 is disposed in the upper case 112. The release button 1123 engages with the coupling hook 125 formed at the water tub 120 to fix the water tub 120. When the release button 1123 is operated, the release button 1123 is lowered, and the engagement of the coupling hooks 125 is released, so that the water tub 120 is detached.

The air passage insertion groove 1125d is a groove into which the air passage 128 formed in the water tub 120 is inserted. When the water tub 120 is mounted, the air passage insertion groove 1125d is disposed to overlap up and down the air passage 128 formed in the water tub 120. The air passage insertion groove 1125d extends to the left and right storage portion insertion grooves 1125b, 1125 c.

The guide projection 1125e is a constituent element for guiding the water tub 120 to a correct position when the water tub 120 is inserted into the water tub seating portion 1125. A groove into which the guide protrusion 1125e is inserted is formed at a position of the water tub 120 corresponding to the guide protrusion 1125 e.

Referring to fig. 19, a guide protrusion 1125e is formed at the rear end of the right side storage part insertion slot 1125 c. Alternatively, although not shown, the guide protrusion 1125e may be formed at the rear end of the left storage portion insertion groove 1125 b.

Preferably, the guide protrusion 1125e is alternatively formed at any one of the right side storage part insertion groove 1125c and the left side storage part insertion groove 1125 b. This is to ensure a storage capacity equal to or greater than a predetermined value in the storage unit 123.

A heater arrangement portion 1126 is arranged in the upper case 112. The heater arrangement portion 1126 is a constituent element that forms a space into which at least a part of the heater 130 is inserted and arranged. The heater arrangement portion 1126 is a surface that is arranged to overlap the heater 130 vertically, out of the lower surface of the upper case 112.

Referring to fig. 9, the heater arrangement portion 1126 is formed recessed upward from the lower surface of the upper case 112. At least a portion of the heater 130 is inserted into the recessed groove of the heater arrangement portion 1126, so that the height of the cleaning module 100 can be further reduced.

The heater arrangement portion 1126 may be formed in a shape similar to a quadrangle. Specifically, the heater arrangement portion 1126 is formed in a quadrangular shape, and may be formed in a curved surface in which each corner is not bent but curved.

The area of the heater arrangement portion 1126 projected to the floor surface is larger than the area of the heater 130 projected to the floor surface when viewed from the upper side. With this arrangement, the water droplets condensed in the heater arrangement portion 1126 fall outside the heater 130 without falling to the heater 130. Therefore, the performance of the heater 130 is prevented from being lowered due to the drop of water to the heater 130.

The heater arrangement portion 1126 of the upper case 112 is formed corresponding to the heater arrangement portion 126 of the tub 120. That is, the first inclined surface 1126a of the heater arrangement portion 1126 of the upper housing 112 corresponds to the first inclined surface 126a of the heater arrangement portion 126 of the water tub 120, the second inclined surface 1126b of the heater arrangement portion 1126 of the upper housing 112 corresponds to the second inclined surface 126b of the heater arrangement portion 126 of the water tub 120, and the third inclined surface 1126c of the heater arrangement portion 1126 of the upper housing 112 corresponds to the third inclined surface 126c of the heater arrangement portion 126 of the water tub 120. Thus, the water droplets formed in the heater arrangement portion 1126 of the upper case 112 flow down the first to third inclined surfaces 1126a to 1126c without falling down to the heater 130.

The heater 130 is disposed obliquely to the floor surface, and the cleaning module case 110 includes an inclined surface disposed parallel to the upper surface of the heater 130. Specifically, referring to fig. 8, the second inclined surface 1126b of the cleaning module case 110 may be disposed in parallel with the heater 130. With this arrangement, heat discharged from the upper surface of the heater 130 in the vertical direction of the upper surface is uniformly transferred to the second inclined surface 1126b, so that the second inclined surface 1126b can be uniformly heated. Therefore, there is an effect of preventing one side of the tub 120 from being overheated to be damaged.

The air inflow port 1111 is formed at one side of the cleaning module case 110. The air outlet 1121 is formed in the cleaning module case 110 and is disposed above the air inlet 1111. The air flows into the inside of the cleaning module 100 through the air inlet 1111, and absorbs heat remaining in the inner space of the cleaning module 100 to be heated. The heated air expands and rises. Accordingly, the heated air is located at an upper portion in the inner space of the cleaning module 100, and since the air discharge port 1121 is disposed at a position higher than the air inflow port 1111, the air can be easily discharged to the outside of the cleaning module 100 through the air discharge port 1121.

The air inlet 1111 is disposed below the heater 130, and the air outlet 1121 is disposed above the heater 130. Thereby, the air flowing into the internal space of the cleaning module 100 through the air inlet 1111 is discharged to the outside of the cleaning module 100 through the air outlet 1121 via the outside of the heater 130. Accordingly, the inflow air may absorb heat that may remain in the upper partition wall 1122 or the lower partition wall 1112 while passing through the outside of the heater 130 and be discharged to the outside of the cleaning module 100.

The air outlet 1121 is arranged in the opposite direction of the air inlet 1111 with respect to the rotation axis x as seen from the side. Referring to fig. 4 and 10, the air inflow port 1111 is disposed at a lower portion of the rotation axis x, and the air discharge port 1121 is disposed at an upper portion of the rotation axis x. In cleaning, the rotation axis x is disposed horizontally with respect to the floor surface and is disposed along the traveling direction. The air inlet 1111 is disposed at a lower portion of the rotation axis x, and the air outlet 1121 is disposed at an upper portion of the rotation axis x, so that air can always have an upward flow inside the cleaning module 100.

The air outlet 1121 is disposed outside the air inlet 1111. Specifically, referring to fig. 1, the right air outlet 1121 is disposed on the right side of the air inlet 1111, and the left air outlet 1121 is disposed on the left side of the air inlet 1111. With this arrangement, the air flows rearward through the air inlet 1111, collides with the upper partition wall 1122 or the lower partition wall 1112, changes its direction outward, and flows along the partition walls 1112, 1122. Accordingly, the air absorbs heat emitted from the outer side surfaces of the partition walls 1112, 1122 while flowing along the partition walls 1112, 1122, thereby preventing heat transfer to other components.

The air outlet 1121 is disposed on a side surface of the cleaning module case 110. Specifically, the air discharge port 1121 is formed in a side surface of the upper housing 112. Referring to fig. 1, a left air discharge port 1121 is formed at a left side surface of the upper housing 112, and a right air discharge port 1121 is formed at a right side surface of the upper housing 112. With this arrangement, the air flows from the front to the rear in the air inlet 1111, but the air flows from the inside to the outside in the air outlet 1121 with the direction of the air flow being switched. Therefore, the air flows in the internal space of the purge module 100 to form a vortex, and thus, the heat remaining in the components disposed at the corners can be absorbed.

The air outlet 1121 is disposed further rearward than the air inlet 1111. During cleaning, the cleaning module 100 cleans a cleaning area while advancing. At this time, according to the law of inertia, as the cleaning module 100 advances, air located in front of the cleaning module 100 can easily flow into the cleaning module 100 inner space via the air inflow port 1111, and a sufficient flow amount of air can be supplied to the interior of the cleaning module 100.

The air inlet 1111 is disposed on the front surface of the cleaning module case 110. Specifically, the air inflow port 1111 is formed on the front surface of the lower housing 111.

The drain port 122 may be disposed at a connection portion between the front storage portion 123b and the right storage portion 123c.

The water tub 120 includes a storage 123. The storage 123 serves as an internal space of the water tub 120 and is a space capable of storing water. The storage part 123 may be formed in a U shape opened at the rear when the tub 120 is viewed from the upper side. The storage part 123 may be divided into a front storage part 123a, a left storage part 123b, and a right storage part 123c.

The water tub 120 includes an air hole 124. The air holes 124 are holes through which air flows into the inside of the tub 120. If the water stored inside the water tub 120 is discharged to the outside, the pressure inside the water tub 120 is reduced, and in order to compensate for the reduced pressure, air flows into the inside of the water tub 120 through the air hole 124.

An air hole 124 is formed at an upper end of the water tub 120. Specifically, the air hole 124 is formed at the rear end of the left storage portion 123 b. In contrast, the air hole 124 may be formed at the rear end of the right storage portion 123 c.

The light emitting module 150 may be disposed behind the air inlet 1112. With such a configuration, the light emitting module 150 can be cooled by the air flowing in from the air inlet 1112.

The light emitting module 150 may be disposed in plural along the front surface to the left or right.

The light emitting module 150 may be composed of a light emitting member 151 and a diffusion plate 152.

The light emitting member 151 may be composed of a plurality of LEDs. The light emitting member 151 irradiates light to the front or lower portion.

The diffusion plate 152 is disposed in front of the light emitting member 151, and diffuses light irradiated from the light emitting member 151.

Referring to fig. 10, the diffusion plate 152 may be formed in a curved surface protruding forward. With such a configuration, the air flowing in from the air inlet 1111 moves along the diffusion plate 152, and the air resistance can be minimized.

The wiper assembly 160 cleans the floor surface using water or steam. The wiper assembly 160 receives steam from the heater 130 and cleans the floor surface wet using friction and steam.

The wiper assembly 160 may be composed of a wiper 161 and a wiper motor 162.

The wiper 161 is disposed on the lower surface of the lower case 111. Specifically, a groove recessed upward is formed in the lower case 111 so that the wiper 161 can be disposed, and at least a part of the wiper 161 is inserted into the groove and provided in the lower case 111.

The wiper 161 may be formed in a circular shape when viewed from above. A rotation shaft extending upward and downward is formed in the center of the wiper 161. The wiper 161 may clean the floor surface by friction while rotating around the rotation axis.

The pair of wipes 161 may be disposed on the left and right sides around the rotation axis x.

The wiper motor 162 is a component for rotating the wiper 161. The wiper motor 162 is disposed above the wiper 161 and on the rotation shaft of the wiper 161.

The wiper motor 162 is provided on the upper surface of the lower case 111.

The wipe motor 162 is arranged corresponding to the number of wipes 161. The wiper motor 162 may be disposed in a pair about the rotation axis x.

Specifically, referring to fig. 10, the wiper motor 162 is disposed above the air inlet 1111 and below the air outlet 1121 when viewed from the side. Referring to fig. 11, the wiper motor 162 is disposed outside the air inlet 1111 and inside the air outlet 1121. With this arrangement, the wiper motor 162 is sufficiently cooled by the air flowing in, and thus has an effect of not being damaged by the heat of the heater.

The shielding member 170 shields a front space in which the suction port 181 is disposed and a rear space in which the wiper 161 is disposed, and blocks diffusion of the vapor discharged from the wiper 161 to the suction port 181.

The shielding member 170 is disposed in the cleaning module case 110 and between the suction port 181 and the wiper 161.

Without the shielding member 170, the heat or steam discharged from the wiper 161 can diffuse forward and flow into the suction port 181. The steam flowing in through the suction port 181 reaches the cleaner body through the dust flow path 180 and the extension pipe 200. In this process, there is a problem in that the dust flow path 180, the extension pipe 200, and the cleaner body are overheated, so that if the user touches the constituent elements, they may be scalded, and other electronic devices located near a plurality of the constituent elements may be damaged. In order to solve such a problem, the cleaner of the present invention blocks heat or steam discharged from the cloth 161 from flowing into the suction port 181 by providing the shielding member 170.

The shielding member 170 may be divided into a central portion 171, a first extension portion 172, and a second extension portion 173.

The center portion 171 is disposed rearward of the suction port 181 and extends straight outward.

The first extending portion 172 extends outward from the end portion of the central portion 171 and extends curvedly.

The second extending portion 173 extends outward from the rotation axis of the wiper 161 and extends straight.

The first extension 172 is formed in a curved surface protruding forward or inward. With this arrangement, the inner end of the first extension 172 is disposed further rearward than the outer end. Therefore, when the cleaning module 1000 advances, dust remaining in the cleaning area can be concentrated to the central portion along the first extension portion 172 and sucked into the suction port 181, so that cleaning performance can be improved.

The second extension 173 is disposed in front of the auxiliary wheel. With this arrangement, dust remaining in the cleaning area is prevented from being caught on the auxiliary wheels and disabling the auxiliary wheels.

The shielding member 170 may include a plurality of projections 170a, 170b.

The first projection 170a projects toward the cleaning region.

The second projection 170b is disposed apart from the first projection 170a at a rear of the first projection 170a and projects toward the cleaning area.

The cross section of the shielding member 170 may be formed in a W shape when viewed from the side.

The second protrusion 170b protrudes further downward than the first protrusion 170 a.

The first projection 170a is disposed in front to sweep out larger dust. The second projection 170b is disposed rearward, seamlessly sweeping out smaller dust. The shielding member 170 of the present invention has two stages of projections 170a, 170b, so that dust can be more effectively swept out.

The dust flow path 180 is a flow path through which air containing dust flows inside the cleaning module 100. An inlet end of the dust flow path 180 is connected to the suction port 181, and an outlet end of the dust flow path 180 is connected to the extension pipe 200.

The suction port 181 is a hole through which dust and air existing in the cleaning region flow into the cleaning module 180.

The suction port 181 is formed at the front end of the lower surface of the lower case 111. The suction port 181 is disposed between the left side cloth 161 and the right side cloth 161.

The dust flow path 180 is disposed at a lower portion of the heater 130. The heat of the heater 130 may be finely discharged to the lower portion. The air flows together with the dust inside the dust flow path 180, and thus can absorb heat discharged from the heater 130 to the lower portion. Accordingly, heat discharged from the heater 130 to the lower portion is blocked from being transferred to other components to prevent the other components from being damaged.

The PCB190 is a substrate configured by a control unit (not shown) for controlling the cleaning module 100, and is capable of flowing electricity and being configured by communication lines.

The PCB190 is electrically connected with the main body.

The PCB190 and a plurality of components provided to the PCB190 have a characteristic of being weak against heat, and can be cooled by air flowing in through the air inlet 1111 and discharged from the air outlet 1121.

The PCB190 is disposed on a flow path of air flowing in from the air inlet 1111. Referring to fig. 7, pcba 190 may be disposed at the upper portion of the right wiper motor 162. Therefore, the PCB190 is disposed above the air inlet 1111 and below the air outlet 1121 when viewed from the side. The PCB190 is disposed outside the air inlet 1111 and inside the air outlet 1121. With this configuration, the PCB190 is sufficiently cooled by the inflow air, and has an effect of not being damaged by the heat of the heater 130.

Hereinafter, the operation of the vacuum cleaner of the present invention configured as described above will be described.

The cleaning module case 110 includes an air inlet 1111 into which air flows and an air outlet 1121 from which air is discharged.

Referring to fig. 10, an air outlet 1121 is disposed above the air inlet 1111. Specifically, the air inlet 1111 may be disposed at a lower position than the heater 130, and the air outlet 1121 may be disposed at an upper position than the heater 130. With such a configuration, the air flowing inside the cleaning module 100 flows close to the heater 130, and thus heat can be extracted from the heater 130 and discharged to the outside of the cleaning module 100, thereby having an effect of preventing a plurality of electronic devices from being damaged by the heat emitted from the heater 130.

Referring to fig. 11, the air outlet 1121 may be disposed further outside than the air inlet 1111. With this arrangement, the air flowing in from the air inlet 1111 rearward is converted to flow direction and is discharged laterally from the air outlet 1121, so that the air flows in the inner space of the cleaning module 110 to form a vortex, and the heat remaining in the components disposed at the corners can be absorbed.

The lower partition wall 1112 or the upper partition wall 1122 is disposed on the periphery of the heater 130, and separates an internal space in which the heater 130 is disposed from an external space in which other members are disposed. Therefore, the heat discharged from the heater 130 is blocked from being radiated to the outside. In addition, heat emitted from the heater 130 remains around the heater 130, so that the thermal efficiency of the heater 130 can be improved by the heat-retaining effect.

The wiper motor 162 or the PCB190 is disposed in a flow path of the air flowing in from the air inlet. With such a configuration, the wiper motor 162 or the PCB190 may be sufficiently cooled, thereby having an effect of not being damaged by heat emitted from the heater 130.

The shielding member 170 is disposed in the cleaning module case 110 and between the suction port 181 and the wiper 161. The shielding member 170 prevents the peripheral components from being thermally damaged or the user from being burned by blocking the inflow of heat or steam discharged from the cloth 161 from the suction port 181, which is caused by the steam flowing in the extension pipe 200 through the dust flow path 180.

While the preferred embodiments of the present invention have been illustrated and described, the present invention is not limited to the specific embodiments described above, and various modifications can be made thereto by those skilled in the art without departing from the spirit and scope of the present invention as claimed in the appended claims, and such modifications should be individually understood without departing from the technical spirit or scope of the present invention.
