The hybrid type cleaner according to the embodiment of the present invention can perform both indoor cleaning and air cleaning functions by the cleaning unit 120 using one motor 113 built in the main body 110, And the space utilization can be increased.

Hereinafter, a hybrid type vacuum cleaner according to an embodiment of the present invention will be described in more detail.

The main body 110 includes a main body casing 111, a main body cover 112, a motor 113, a suction fan 114, and filters 115a, 115b, and 115c as shown in FIGS. .

The main body casing 111 is provided with a first air inlet 111 formed at a lower portion thereof and is provided with a dust chamber 110 which is opened at an upper portion thereof so as to receive dust that is filtered from the air sucked through the first air inlet 111, (111b). As shown in the figure, the body casing 111 is made of a transparent material so that the amount of dust caught inside the body casing 111 can be visually confirmed.

The main cover 112 is coupled to an upper portion of the main body casing 111 to cover an upper portion of a dust chamber 111b formed therein and includes an air outlet 112a and a second air inlet 112b. 4, an air outlet 112a is formed on the upper surface of the main cover 112, and a second air inlet 112b is formed on the side surface of the main cover 112 to communicate with the air outlet 112a . The first air intake port 111 is formed at the lower end of the main body casing 111 so that air can be sucked through the suction head 121 and the communication pipe 122. The second air intake port 112b is formed in the main cover 112 so that air can be sucked directly from the room without going through the suction head 121 and the communication pipe 122. [ According to the configuration of the second air intake port 112b, air is sucked directly from the room without going through the suction head 121 and the communication pipe 122 of the cleaning section 120, and is then discharged through the air discharge port 112a 130, the hybrid type vacuum cleaner of the present invention can function as an air purifier in normal times without cleaning. It can be noted that in the present invention, a single motor 113 used for performing a cleaning function is unified to have a simpler configuration. For this purpose, the suction fan 114 and the motor 113 are disposed at substantially the uppermost position from the lower side of the main body cover 112, and disposed at a position higher than the first air suction port 111. Although not shown in detail, the first air inlet 111 is additionally provided with a simple opening / closing door (an opening / closing valve that is automatically opened when the air purifying function is changed to a cleaning function or a manually operated sliding door) When the type cleaner performs the cleaning function, the first air intake port 111 is closed by the opening / closing door, and when the type air cleaner performs the function as the air purifier, the first air intake opening 111 is opened by the opening / closing door . Thus, when the air purifier functions as an air purifier, air can be sucked through the second air intake port 112b without passing through the cleaning unit 120, and then the air purifier 130 can be sent.

However, it is needless to say that a small auxiliary motor and an exhaust fan may be additionally provided in the purifier casing 131 to operate as an air purifier. Such a configuration may be a disadvantage in terms of complicated configuration because a small auxiliary motor and an exhaust fan must be separately provided. However, it may be advantageous in that the noise is reduced because the intake air does not have to pass through the filters.

In addition, the main body cover 112 has a ring-shaped handle 112c protruding upward at a front end thereof. An operation switch 112d is provided at the lower front of the handle 112c.

An insertion protrusion 112e is formed on the rear surface of the handle 112c to be inserted when the purifier casing 131 of the air purifier 130 is docked on the upper surface of the main cover 112. [ Accordingly, an insertion concave portion 131c is formed on the front surface of the purifier casing 131 so that the insertion protrusion 112e is inserted in a long shape upward from the lower end. Since the upper surface of the main body cover 112 and the lower surface of the purifying portion casing 131 are smoothly moved by the insertion of the insertion protrusion 112e formed on the other side of the main body cover 112, It is possible to utilize it as an area for.

The insertion protrusion 112c is formed not only vertically on the rear surface of the handle but also extends horizontally to extend horizontally to form an L-shaped member crossing the center of the upper surface of the main cover 112, Which serves also as a rib for enhancing structural stability with respect to the substrate 112. Here, the horizontal part of the insertion protrusion 112c, which crosses the center of the top surface of the main cover 112, should be formed to be much thicker than other parts of the top surface of the main cover 112.

The motor 113 of the main body 110 is installed on the lower surface of the main body cover 112 with the shaft facing downward. In the present invention, the motor 113 serves to provide a driving force for rotation of the suction fan 114 when performing a cleaning function and in all cases where the function of the air cleaner is performed.

The suction fan 114 of the main body 110 is installed on the shaft of the motor 113 and generates a suction force for sucking air through one air intake port and the second air intake port 112b while rotating. The suction fan 114 is preferably provided as a double cyclone to increase the suction force. The suction fan 114 is installed in the main body cover 112 to suck air from the first air intake port 111 formed at the lower portion of the main casing 111 to perform the cleaning function through the suction head 121 . In addition, the suction fan 114 is installed at a position higher than the first air suction port formed on the side surface of the main body cover 112 to perform a cleaning function, and when performing the air cleaning function, the suction fan 114 is also rotated from the second air suction port 112b Let air inhale.

The filter of the main body 110 is installed to be drained in the dust chamber 111b of the main casing 111 while the upper end thereof is supported by the main cover 112 and is sucked from the first air suction port 111 It acts to filter dust from air. The filter is provided with a primary filter 115a for filtering relatively large dust particles as shown in FIG. 5, and a micro filter 115b and a HEPA filter 115c for filtering fine dust. The primary filter 115a and the microfilter 115b are formed in a cup shape as shown in the drawing to increase the contact area with the air sucked in the dust chamber 111b of the main casing 111, The HEPA filter 115c is formed in a circular shape so as to be positioned at the upper end of the microfilter 15b.

The cleaning unit 120 includes a suction head 121 and a communication pipe 122 as shown in FIG. As shown in the drawing, the suction head 121 can be tilted at a lower end of the communicating tube 122 so that the angle of the suction head 121 can be adjusted during the cleaning. The communicating tube 122 has a plurality of tubes, Configuration.

The air purifier 130 is docked on the upper portion of the main cover 112 in a state of being connected to the air outlet 112a of the main cover 112 to purify the air discharged from the air outlet 112a, . The air purifier 130 includes a purifier casing 131, a photocatalyst material 132, a mud lamp 136, and a mounting member 136 as shown in FIG.

The purifier casing 131 of the air purifier 130 is provided with an operation window 131a for easily displaying a surrounding state including an operation temperature and a room temperature. An insertion concave portion 131c for inserting the insertion protrusion 112e of the main cover 112 is formed on the front surface of the purifier casing 131 so as to extend upwardly from the lower end. 9 and 10, a plurality of mounting protrusions 131c protruding in an upward tilting direction toward the front are formed in the interior of the insertion recess 131c formed in the purifier casing 131, (131b) are vertically spaced. Correspondingly, an insertion protrusion 112e is formed on the rear surface of the handle 112c of the main cover 112 so as to be inserted into the insertion recess 131c formed in the purifier casing 131. The insertion protrusion 112e, A plurality of mounting grooves 112f are formed so that the mounting protrusions 131b are fitted thereinto. Such a structure allows the main cover 112 to be mounted on the purifier casing 131 and allows the purifier casing 131 to be mounted on the main body cover 112 on the contrary. In other words, in the case of the above-described mounting structure, the purifier casing 131 and the main body cover 112 can be interlocked with each other, and the air purifier 130 and the main body 110 can be interlocked with each other.

10, the charging protrusion 131b is provided with a charging terminal 131d so that when the main body 110 is mounted on the air purifier 130, The battery is connected to the power source through the charging terminal 131d and charged for driving the motor 113 in a separated state. Accordingly, the fixing member 136 is installed on the rear surface of the purifier casing 131, and the purifier unit 136 is mounted on the bracket installed in the wall of the room so as to allow power to pass through the purifier casing 131, To be supplied. In the case of such a mounting member 136, the fixing member casing 131 is formed to extend downward from the upper part of the outer surface of the casing 131 so as to perform a mounting function and a power supply function without hitting the whole design.

The purifier casing 131 is docked on the top of the main body cover 112 to receive the air discharged from the air discharge port 112a of the main cover 112, And a reaction chamber 131b having a light source for irradiating light of a certain wavelength to activate the photocatalyst while receiving the photocatalyst material 132. [ Here, the light source is irradiated with light having a wavelength of 254 nm to activate titanium dioxide (TiO ₂ ), which is a photocatalyst contained in the photocatalyst material 132. Porous cover assemblies 132, 133, 133a, 134 and 135 are provided at the upper end of the purifier casing 131 to allow purified air to be discharged while covering the reaction chamber 131b.

The photocatalyst material 132 is accommodated in a reaction chamber 131b formed in the purifying part casing 131 and serves to purify the air supplied to the reaction chamber 131b by a photocatalytic action. As shown in FIG. 8, the photocatalyst material 132 is formed as an aggregate of nano glass tubes coated with a photocatalyst. Titanium dioxide (TiO ₂ ) is suitable as the photocatalyst. As described above, the photocatalyst material 132 is provided as an aggregate of nano glass tubes coated with titanium dioxide, which is a photocatalyst, to maximize the contact area with the air in the limited space of the reaction chamber 131b, So that it can be performed at a sufficient level. As a result, the harmful substances contained in the air collide with the hydroxyl radicals generated from the photocatalyst and are decomposed into harmless minerals.

Furthermore, in the embodiment of the present invention, when applying the photocatalyst to the nano-glass tube of the photocatalyst material 132, the citrus oil extracted from the citrus peel, which is a recycled material, is applied in a mixed state with the photocatalyst, do. In order to uniformly mix the photocatalyst and the citrus oil, an original photocatalyst-oil mixer is used in the production, which will be described later in detail.

The mood lamp 136 is installed on the upper part of the purifying part casing 131 and the purified air is discharged from the discharge hole 135a formed in the upper part of the purifying part casing 131, As shown in FIG.

Hereinafter, the photocatalyst-oil mixer having the unique structure developed for the uniform mixing of the photocatalyst and the citrus oil will be described in detail. It is possible to realize an air purification function of the photocatalyst and a high quality and eco-friendly photocatalyst material 132 of the antibacterial function of the citrus oil extracted from the orange peel.

FIG. 11 is a perspective view of a photocatalyst-oil mixer for producing a photocatalyst-citrus oil coating liquid used for a photocatalyst material in a hybrid type vacuum cleaner according to an embodiment of the present invention, FIG. 12 is a perspective view of a hybrid type vacuum cleaner according to an embodiment of the present invention, Oil mixer for producing a photocatalyst-citrus oil coating liquid used for a photocatalyst material in a hybrid type vacuum cleaner according to an embodiment of the present invention. FIG. 13 and FIG. 14 are cross- Fig. 6 is a series of reference drawings for explaining the operation and operation of a photocatalyst-oil mixer for producing a coating liquid. Fig.

As shown in FIG. 11 and FIG. 12, the photocatalyst-oil mixer includes a main body pipe 10, an injection nozzle 20, a phase change module 30, a redoing module 40, a heating module 50 ).

The main tube 10 is supplied with free water and citrus oil, which are ultrafine particles of a photocatalytic diluent, in the phase conversion module 30, and performs a primary mixing while strongly contacting and mixing. The main tube 10 is connected to the phase change module 30 so that the tip of the main tube 10 can receive free water of the photocatalytic dilution liquid sent from the phase conversion module 30, And also receives the citrus oil from the injection nozzle 20. Inside the body having a pipe shape, a protrusion 11 for reducing the inner diameter and widening the inner diameter and forming a narrow venturi tube-shaped flow path at the intermediate point is provided. Such protrusions 11 induce the free water of the photocatalytic diluent and the citrus oil to make strong contact with each other while flowing at an increased rate in the relatively narrow channel 10a by the venturi effect, as can be seen in Fig. The chambers 11a and 11b connected to the citrus oil tank through the first supply pipe 62 of the three-way valve 60 for storing and temporarily storing the citrus oil are formed in the protrusion 11, A plurality of first injection holes 11c are formed along the circumferential direction of the inner circumferential surface to receive and discharge the citrus oil from the chambers 11a and 11b on the inner circumferential surface of the intermediate point corresponding to the point where the flow paths are narrowly formed, A plurality of second injection holes 11d for supplying and discharging the citrus oil from the chambers 11a and 11b are formed at the rear end points of the protrusions 11 along the circumferential direction of the rear end. Thereby, it is possible to supply the citrus oil at the same time as the injection nozzle 20 at a more various points, so that it is possible to more effectively contact the free water. In particular, the citrus oil injected through the first injection hole 11c formed at the midpoint of the projection 11 can vigorously contact the free water flowing at the fastest speed, The citrus oil injected through the second injection hole 11d formed so as to be in a calm contact with the free water flowing at a relatively slow speed. With this diversity, it is possible to increase the effect of mixing and contacting the free water of the photocatalytic diluent with the citrus oil, and thus the mixing quality can be raised to a high level from the beginning.

14, an axial flow fan 12 for sending out the free radical of the photocatalytic dilution liquid, which is sent out from the centrifugal fan 32 of the phase conversion module 30, in the form of a whirlwind Respectively. As shown in FIG. 13, when the axial flow fan 12 is provided and operated, the flow rate of the free water and the flow of the citrus oil is rapidly formed by the venturi effect and strong contact is made with each other, The complex action of mixing with citrus oil occurs in the form of strong whirlwind. Therefore, contact and mixing between free water and citrus oil, which is a photocatalytic dilution of ultrafine particulate state, and thus initial mixing, can occur very quickly and effectively. For reference, it is sufficient that the axial fan (12) has the same shape as the fan adopted in the air circulator used in recent households.

The injection nozzle 20 serves to supply the citrus oil in the main tube 10 in a direction coinciding with the flow direction of the free water. For this, the injection nozzle 20 is connected to the citrus oil tank through the second supply pipe 63 of the three-way valve 60 to receive the liquid citrus oil. In the state of passing through the front end wall of the main pipe 10, Is formed so as to face the flow path formed narrowly by the projecting portion (11) while being positioned on the center line of the main body tube (10). 12, the injection nozzle 20 includes a first nozzle unit 21 formed from the wall of the main tube 10 to a center line thereof and a second nozzle unit 21 extending from the first nozzle unit 21 to the center line of the main tube 10, And a second nozzle portion 22 which extends along the narrow path 10a and whose end is located close to the narrow flow path 10a by the protrusion 11. [ Such injection nozzles 20 assist in accelerating the flow rate of free water while jetting the citrus oil in the vicinity of the narrow flow path 10a by the projections 11 in the direction of the free flow of the photocatalytic diluent. This contributes greatly to the contact of the free radical of the photocatalytic diluent and the citrus oil at a faster velocity in the narrow channel 10a at the midpoint of the projection 11 of the main tube 10.

The phase conversion module 30 converts the diluted photocatalyst supplied through the transfer pipe P1 into the ultrafine particulate free phase. To this end, the phase conversion module 30 has a flange and has a pipe-shaped body communicating between the transfer pipe P1 and the main pipe 10, and a photocatalytic dilution liquid, which is transferred through the transfer pipe P1, And a spray head 31 for spraying the water into the free water. The spray head 31 may be a spray head 31 (nozzle) applied to a water spraying fire extinguishing system, but it is preferably modified to have improved corrosion resistance and durability. When the photocatalytic dilution liquid supplied from the transfer pipe (P1) is converted into ultrafine particulate free water without using it as it is, the contact area for contacting the citrus oil can be secured at a remarkable level, It is very important in that it is possible.

In addition, a centrifugal fan (32) is provided inside the phase conversion module (30) to deliver the free water sprayed from the spray head (31) at a lower speed. In the case of the axial flow fan 12, if the centrifugal fan 32 has a function for pushing and discharging the free water, the centrifugal fan 32 will overcome the resistance due to the installation of the spray head 31, And is suitable for dispensing to the centrifugal fan (32). In the present invention, the centrifugal fan (32) and the axial fan (12) are disposed side by side in series to maximize the advantage between the centrifugal fan (32) and the axial flow fan (12).
