In addition, the right side surface 267 is preferably disposed toward the main filter unit 250.

In addition, the upper surface 265 and the rear surface 268 may be implemented detachably as shown in Figure 5b. That is, the detachable protrusions 265a and 268a formed on the upper screen 256 and the rear screen 268 are detached to the detachable grooves 265b and 268b formed on the frame of the auxiliary filter unit 260. This is convenient when assembling or cleaning.

Of course, the front surface 261, the lower surface 263, and the left side 266 can also be separated separately, and the front surface 261 and the lower surface 263 can also take the form of a screen.

In addition, the sub-filter unit 260 may be implemented in a form (trapezoid) having a larger surface area from the left side to the right side, thereby improving the suction discharge efficiency by eliminating the bottleneck of the air flow.

Therefore, since the large dust or fine dust accumulated in the dust collecting container 210 is evenly distributed or evenly distributed around the auxiliary filter unit 260, it can be used without being emptied for a long time, and in particular, the dust to the main filter 215 is blocked. The effect of suppressing the phenomenon as much as possible eliminates the need for frequent dust cleaning.

The auxiliary filter unit 260 is supported by the separating plate 270 and the support 273 separating the mounting chamber 255 and the dust collecting chamber 213 on which the main filter unit 250 is mounted.

The separating plate 270 may be provided with a mounting groove 271 in which one side lower surface of the auxiliary filter unit 261 is seated.

The impeller 813 sucks air in the direction of the center of rotation and exhausts it in the circumferential direction, and prevents moisture or the like of the motor driving part 811 from penetrating.

The impeller casing 830 consists of a circumferential case 831 surrounding the impeller 813, a suction case 833 connected to the first through hole 161, and an outlet 835 formed in the circumferential case 831. It is.

Since the discharge port 835 is formed at right angles to the circumferential direction, the air discharged to the discharge port 835 passes along the longitudinal direction of the motor driving unit 811, thereby improving cooling efficiency. Since the cooling efficiency can be increased, the motor 810 having a relatively small capacity can be used to realize small size, light weight, and low noise.

In addition, it is preferable that the motor cooling casing 850 is further installed in the motor driving unit 810.

On the circumferential surface of the motor cooling casing 850, a cooling air suction port 853 connected to the second through hole 163 and a cooling air exhaust port 855 connected to the third through hole 165 are preferably formed. .

That is, when the cooling fan 815 of the motor driving unit 810 rotates, the cool air inlet 885 is sucked in the cool air in the main body 110. The cold intake air flows toward the cooling fan 815 and deprives heat of generation. The heated air is discharged by hitting the dust collector 210 of the barrel mounting groove 160 through the cooling air vent 855.

By the cooling flow of the motor driving unit 810, even if the size of the motor 810 is reduced, the efficiency is high and can be sucked to the required capacity.

In addition, since warm air collides with the dust collector 210 and is exhausted, there is an effect of preventing dust dispersion on the bottom surface and reducing noise.

On the other hand, between the motor driving unit 810 and the motor cooling casing 850, the flow separation packing 860 is preferably further installed.

That is, when cool air flows into the motor casing 850, the flowed air flows into the motor driving unit 810, and the warm air flowing therein comes out to the outer circumferential surface of the motor driving unit 810 and cools the air exhaust. By discharging to 855, it is possible to further increase the cooling efficiency by preventing the inlet air and the outlet air meet each other.

In particular, since the motor cooling casing 850 is made of a transparent material, as shown in FIG. 9, the assembly of the flow separation packing 860 may be visually inspected.

The suction case 833 and the motor cooling casing 850 are provided with mounting pieces 837 and 857 to be mounted to the motor mounting groove 180. The motor cooling casing 850 is provided with a wire drawing hole 856 for applying power to the motor.

In this state, pressing the button 930 pushes the engaging projection 571a toward the pushing piece 940 while descending along the guide 920. Since the engaging projection 571a is inclined at the portion pushed by the milling piece 940, when the engaging projection 571a is pushed by the inclined portion, the water tank 571 automatically comes forward and is easily separated.

Therefore, the coupling protrusion 571a is separated from the through hole 910, and can be easily separated by pulling the bucket 571.

10, 11, and 14, the exhaust part 700 includes an exhaust groove 730 formed in the rear mounting case 520, a filter 720 mounted in the exhaust groove 730, and The filter cover 710 opens and closes the exhaust groove 730.

Since the exhaust groove 730 is in communication with the front mounting case 510, it is preferable that a net-shaped frame is formed to prevent the filter 720 from being separated.

The filter 720 uses the HEPA filter 720 to filter out fine dust and at the same time to exhaust the exhaust gas to the outside while absorbing the exhaust gas, thereby reducing the speed of the discharged air and reducing the noise, due to the discharged air. Dust can be prevented from scattering. In particular, since the exhaust part 700 is disposed in the main assembly 500, the exhaust part 700 is far from the bottom, and there is almost no fear of dust on the bottom.

The filter cover 710 includes a cover plate 711 having an exhaust hole 712, a detachment protrusion 713 formed on the upper and lower surfaces of the cover plate 711, and an operation unit 715 for operating the detachment protrusion 713. ).

Desorption protrusion 713 is detached to the coupling groove 714 formed on the upper and lower inner peripheral surface of the exhaust groove (730).

The operation part 715 is comprised by the switch which pulls in and detaches the detachment protrusion 713 toward the cover plate 711, and the spring which releases this detachment protrusion 713 again toward the surface when this switch is released. The function of the actuating part 715 is similar to that of the detachable member 900 of the bucket 571.

Steam vacuum cleaner according to the present invention is not limited to the above-described embodiment can be carried out in various modifications within the range allowed by the technical idea of the present invention. For example, the above-described steam vacuum cleaner is composed of a base assembly, a neck assembly, three main assemblies, but it will be apparent to those skilled in the art that the steam vacuum cleaner can be implemented as two base assemblies and two push rod assemblies. That is, the push rod assembly may be provided with a push rod whose end is pivotally supported by the base assembly, and the steam generator 570 may be installed on the push rod, and a dust collecting path may be realized through the outside or the inside of the push rod.

As apparent from the above description, the steam vacuum cleaner of the present invention has the following effects.

First, a base assembly to which the vacuum cleaner is mounted, a main assembly to which the steam generator is mounted, and a neck assembly to connect the exhaust air of the vacuum cleaner to the exhaust of the main assembly while pivotally connecting the main assembly to the base assembly. By constructing, the height and length of the base assembly can be remarkably reduced by separating the vacuum cleaner and the steam generator, thereby achieving light weight and miniaturization.

Second, since the air exhaust port for cooling the suction motor is disposed toward the dust collecting container, the air for cooling the suction motor is discharged by colliding with the dust collecting container, thereby significantly reducing the noise that escapes through the space, as well as the floor surface. Since it is not sprayed toward the bottom, dust dispersion on the bottom surface can be minimized.

Third, since the front neck case is formed integrally with the front mounting case, and the rear neck case can be separated from the rear mounting case, the assembly is not only smooth, but also the steam generating unit mounted on the front mounting case and the PCB to control it. In case of failure, the rear neck case can be left intact, and only the rear mounting case can be disassembled and repaired, thereby improving work efficiency such as after-sales performance and assembly.
