In addition, by adopting a large heater unit, since the steam outlet is also enlarged, it is possible to use the steam outlet for a long time because the steam outlet is not easily blocked by a scale generated in the heater unit.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the vacuum cleaner combined vacuum cleaner according to a first embodiment of the present invention.

1 and 2, the vacuum cleaner according to the first embodiment includes a suction port 100, a body 200, a stick part 301, and an operation handle 303. In this case, the suction inlet 100 and the body 200 are hinged to each other so that the user can clean in a comfortable state, when cleaning, the user grasps the operation handle 303, the body 200 to the rear at a predetermined angle Can be cleaned in a tilted state.

1 and 2, the suction inlet 100, the upper case 110, the lower case 120, the drum brush 125, the motor 130, the impeller 135, the waste container 150, Rotation driving unit 160 and a pair of mop attachment plate (161a, 161b).

The upper case 110 has a hinge coupling portion 111 is hinged to the hinge shaft 202 formed on the lower end of the body 200 at the rear is connected to the hinge, one side of the waste container 150 is inserted Insertion groove 113 is formed. In addition, the upper case 110 is detachably coupled to the transparent cover 101 that can visually check the drum brush 125 (see FIG. 3) rotatably installed inside the suction port 100. The transparent cover 101 allows the user to check whether the drum brush 125 is rotated during cleaning, and the drum brush 101 driven by the driving force transmitted from the motor 130 is caught in the suction port 123. When the rotation is stopped by the quick action it can be prevented that the overload occurs in the motor (130).

The lower case 120 is detachably coupled to the lower side of the upper case 110, and protects the drum brush 125, the motor 130, and the impeller 135 installed therein along with the upper case 110. In addition, referring to FIG. 8, the lower case 120 has an inlet 123 through which the dirt and air of the surface to be cleaned are formed on the front bottom surface, and the drum brush 125 is rotated in the inlet 123. It is possible to install. The drum brush 125 is coupled to a plurality of cleaning ribs 126 made of a soft along the outer circumference.

Furthermore, the lower case 120 has passages 143, 144, and 145 moving inward from the suction port 123 to the waste container 150, and the passages include the first passage 143 and the impeller casing part 144. And a second passage 145. The first passage 143 has an inlet 141 positioned adjacent to the inlet 123 on one side thereof, and the other side thereof communicates with the impeller casing unit 144. One side of the second passage 145 communicates with the impeller casing part 144, and the other side thereof communicates with the waste inlet 153 of the waste container 150. The impeller casing portion 144 has an inner diameter larger than the outer diameter of the impeller 135 so that the impeller 135 is installed in a rotatable state. Accordingly, the dirt introduced into the inlet 141 passes through the first passage 143, the impeller casing 144, and the second passage 145, and is collected in the waste container 150.

In addition, the lower case 120 insulates the vacuum cleaning area of the bottom surface of the lower case 120 where the inlet 123 is formed and the steam cleaning area in which the mops 163a and 163b are disposed so that steam and dirt do not mix with each other. It is provided with a blocking rib 180 (see Fig. 8) to serve. The blocking rib 180 is disposed adjacent to the suction port 123 along the suction port 123.

The blocking rib 180 prevents dirt from flowing into the inlet 123 while being mixed with steam by being mixed with steam while the lower end contacts the surface to be cleaned during cleaning, thereby preventing the wet soil from the steam entering the inlet 141. It can prevent it from inhaling and sticking to the surface to be cleaned again. In this case, the steam is injected from a steam injection hole (not shown) formed at a predetermined position behind the bottom of the lower case 120.

The motor 130 has a power consumption of about 80-100W, for example, rather than a suction motor (power consumption: about 700-800W) used in a general vacuum cleaner. In addition, since the heater unit 240 uses AC power, the motor 130 is preferably an AC motor using the same AC power as the heater unit 240. 3 and 4, the motor 130 includes a drive shaft 131 connected to the center of rotation of the impeller 135 to drive the impeller 135. In this case, the motor 130 is installed in the lower case 120 in a state in which the drive shaft 131 is located parallel to the drum brush 125, accordingly, the motor 130 is a drum brush (through the drive belt 133) 125) to transfer the driving force directly. In addition, one side of the drive shaft 131 of the motor 130 transmits power to the rotation driving unit 160 through a predetermined power transmission means (not shown). Accordingly, the motor 130 simultaneously transmits power to three places of the drum brush 125, the impeller 135, and the rotation driving unit 160 according to the rotational drive of the drive shaft 131.

Referring to FIG. 5, the impeller 135 forms a suction hole 136 disposed adjacent to the first passage 143 at one side center, and the suction hole 136 is formed through the first passage 143. It serves to guide dirt and air into the impeller 135. In addition, the impeller 135 has a predetermined curvature and has a pair of blades 137a and 137b symmetrically formed with respect to the rotation center of the impeller 135. The pair of blades 137a and 137b are arranged at both ends at predetermined intervals so as to form a pair of discharge ports 139a and 139b. Accordingly, the impeller 135 discharges the dirt sucked into the suction hole 136 through the pair of discharge ports 139a and 139b using centrifugal force, thereby introducing the dirt into the waste container 150 through the second passage 145. . In addition, the impeller 135 is not limited to the number of blades 137a and 137b, and as shown in FIG. Of course it is possible. In this case, the impeller 175 may increase the discharge flow rate of air and dirt than the case of a pair of blades. In FIG. 7, reference numerals 179a, 179b, 179c, and 179d denote discharge holes.

The waste container 150 is made of a transparent material at least the top. When the waste container 150 is mounted in the insertion groove 113 of the upper case 110, the waste collection amount collected in the waste container 150 through the transparent upper portion of the waste container 150 exposed to the outside can be easily grasped. To do so. In addition, the waste container 150 forms an exhaust 155 (refer to FIG. 2) at the rear to discharge the air introduced together with the waste to the outside of the waste container 150. The exhaust unit 155 may be provided with a filter (not shown) to remove fine dust contained in the air discharged to the outside of the waste container 150.

The rotation driving unit 160 is disposed at the rear of the motor 130 on the lower case 120, and a plurality of worm gears (not shown) and bevel gears (not shown) are installed inside. The rotation driving unit 160 receives power from the motor 130 and rotates the pair of mop attachment plates 161a and 161b formed in a circle installed on the bottom surface of the lower case 120. In this case, the pair of mop attachment plates 161a and 161b are each provided with a velcro tape (not shown) such that the mop 163a and 163b are detachably attached to the bottom surface thereof.

On the other hand, through the present embodiment, it is also possible to apply a fixing method instead of the rotation method as described above. That is, referring to FIG. 9, the present embodiment includes a mop attachment plate 430 detachably coupled to the rear side of the blocking rib 480 installed at the bottom of the lower casing 420, and a bottom surface of the mop attachment plate 430. It may include a rectangular mop 440 detachable to. In this case, the mop attachment plate 430 has a plurality of coupling grooves 431a, 431b, 431c, and 431d at predetermined intervals on an upper surface thereof, and a part of the bottom surface of the lower casing 420 where the mop attachment plate 430 is located. In the region, a plurality of coupling protrusions 427a, 427b, 427c, and 427d are snap-fitted into the plurality of coupling grooves 431a, 431b, 431c, and 431d.

In addition, the mop attachment plate 430 has a predetermined length so that steam injected through the plurality of steam injection holes 426 formed in the lower casing 420 can be injected onto the surface to be cleaned without being blocked by the mop attachment plate 430. Long hole 433 is formed. Furthermore, the mop attachment plate 430 has a pressing piece 435 protruded from the rear side so that the user can easily separate the mop attachment plate 430 from the lower casing 420 by using a foot. As such, when the fixing method is applied to the mop 440, the suction port 400 may omit the rotation driving unit 160. In FIG. 9, reference numeral 410 denotes an upper case, 425 denotes a drum brush, and 429 denotes wheels, respectively.

1, 2 and 10, the body 200 includes a front cover 201, and an insertion hole 207 into which the water tank 210 is detachably inserted is disposed on the front cover 201. It is formed, the locking button 211 for locking and unlocking the bucket 210 is installed. In addition, the body 200 has a carrying handle 203 for carrying the cleaner to the upper end side is formed to be inclined forward. In addition, the body 200 has a stick inserting portion 205 extending along the longitudinal direction of the body 200 so that the stick portion 301 is slidably inserted and withdrawn at the rear thereof, and wound the electric wire (not shown). A pair of winding protrusions 251 and 252 protrude from the upper and lower predetermined intervals.

The bucket 210 is inserted into the body 200 only to be withdrawn from the insertion hole 207, the pump 220, the safety valve 230 and the heater unit 240 are all in the body 200 Is installed.

Bucket 210 is made of a transparent material to check the water storage amount through the front of the bucket 210 is exposed to the outside when mounted to the body 200.

The pump 220 receives water from the bucket 210 and supplies the predetermined amount to the heater unit 240 through the water supply pipe 231. In this case, a discharge pipe 233 communicating with the outside of the body 200 is formed at one side of the water supply pipe, and a safety valve 230 is installed at the discharge pipe 233. The safety valve 230 prevents water supplied from the pump 220 from flowing smoothly into the heater unit 240 and flows back into the pump 220 due to a predetermined pressure generated in the heater unit 240. Do it. The discharge pipe 233 serves as a passage for discharging water to the outside of the body (200).

The heater unit 240, unlike a small capacity heater unit applied to a conventional steam cleaner, for example, has a built-in sheath heater (power consumption of about 1200-1900W), the water storage amount is about 700-900cc Large heater unit 240 is used. Accordingly, in the present embodiment, even when the large heater unit 240 and the motor 130 having a power consumption of about 80-100W are used together, power consumption of up to about 1400W is used. Therefore, when the power consumption of the conventional steam cleaner combined vacuum cleaner is assumed to be 2000W, the power consumption can be reduced by approximately 600W.

In addition, since the heater unit 240 is largely manufactured to accommodate a large amount of water, the scale can be attached to the inside much larger than the small heater unit, so the steam supply pipe 241 is easily blocked due to the scale. Can be prevented. In FIG. 10, reference numeral 221 denotes an inflow port.

On the other hand, referring to Figure 10, the pump 220 is disposed on the upper side of the heater unit 240, the overall body 200 is formed slim, but not limited to this configuration through the present embodiment, FIG. As shown in FIG. 11, the pump 520 may be set to be disposed on the side of the heater unit 540. In this case, the convex shape of the body 500 can lower its height to form a vacuum cleaner as a whole. The body 500 shown in FIG. 11 is the same as the configuration of the body 200 shown in FIG. 10, but the position of the pump 520 is changed as described above. In FIG. 11, reference numeral 503 denotes a transport handle, 521 denotes an inlet port, 530 denotes a safety valve, 531 denotes a water supply pipe, 533 denotes a discharge pipe, 601 denotes a stick portion, 603 denotes an operation handle, 605 denotes an operation button, and 607 denotes a stick. Represent each government.

Referring to FIG. 10, the stick part 301 has a predetermined length, and may be used to withdraw or insert from the stick inserting part 205 (see FIG. 2) according to a user's height. In this case, the stick part 301 fixes and releases the stick part 301 through the stick fixing part 307 disposed on the top of the stick inserting part 205.

On the other hand, the operation handle 303 is coupled to the top of the stick unit 301 so that the user can hold, one side of the operation button unit 305 consisting of a plurality of buttons for driving the motor 130 and the heater unit 240 ) Is placed. The user may perform the vacuum cleaning and the steam cleaning together through the operation button unit 305 or may be performed separately.

The operation of the combined vacuum cleaner according to the first embodiment of the present invention configured as described above will be described, but the case of performing the vacuum and steam cleaning together as an example. When the user drives the motor 130 and the heater unit 240 through the operation button unit 305, vacuum cleaning and steam cleaning proceeds together.

First, in the case of vacuum cleaning, as the rotation shaft 131 of the motor 130 rotates in one direction, the drum brush 125, the impeller 135, and the rotation driving unit 160 are driven simultaneously.

Accordingly, as shown in FIG. 12, while the drum brush 125 rotates, the cleaning rib 126 contacts the surface to be cleaned, and the dirt D on the surface to be cleaned is introduced through the suction port 123 to the inlet port 143 of the first passage 143. 141) Transfer around. Subsequently, the dirt D transferred around the inlet 141 is introduced into the inlet 141 by the suction force generated by the rotation of the impeller 135, and passes through the first passage 143 to the suction hole of the impeller 135. 136).

Soil (D) introduced into the impeller 135 is discharged from the discharge port (139a, 139b) by the centrifugal force, and then through the inlet 153 of the waste container 150 through the second passage 145 ( 150). Thus, in this embodiment, since the passages 143, 144, and 145 through which the dirt from the suction port 123 to the waste container 150 are sucked are very short, they do not require high suction power as in the prior art, and thus, they sufficiently remove the dirt D with low suction power. It can be collected, and thus can be maintained as in the prior art without lowering the efficiency of vacuum cleaning while employing the AC motor 14 with low power consumption.

Meanwhile, in the case of steam cleaning, as shown in FIG. 10, the water supplied to the heater unit 240 is converted to a steam state while the sheath heater (not shown) inside the heater unit 240 is heated, and then the steam supply pipe 241. It is sprayed to the surface to be cleaned through the steam injection hole (not shown) of the lower case 120 through

At the same time, the pair of mop attachment plates 161a and 161b rotates according to the driving of the rotation driving unit 160, and rotates the mop 163a and 163b attached to the bottom to wipe the surface to be cleaned by steam.

In this case, as shown in Figure 13, the steam injected toward the surface to be cleaned does not move to the inlet 123 side by the blocking rib 180, the dirt (D) is swept up to the inlet 141 side by the drum brush (125). Since the movement is restricted to the side where steam is injected by the blocking rib 180, the dust is prevented from being entangled by the steam, so that the dirt separated from the surface to be cleaned by the drum brush 125 is stuck to the surface to be cleaned again. Can be prevented.

As described above, the first embodiment uses the AC motor 130 that consumes much less power than the power consumption of the suction motor used in the conventional vacuum cleaner combined vacuum cleaner, on the contrary, the heater unit 240 is conventionally By using the large heater unit 240 of high efficiency and high performance, the power consumption of which is the same as or less than that of the conventional vacuum cleaner combined with vacuum consumption can be greatly improved while the efficiency of steam cleaning is greatly improved. have.

In addition, since the steam outlet 241 is also enlarged by employing the large heater unit 240, the steam outlet 241 is not easily blocked by the scale generated in the heater unit 240, so that it can be used for a long time.
