The present invention relates to a wet and dry vacuum cleaner, and more particularly, to a wet and dry vacuum cleaner that can be used wet or dry arbitrarily without any structural change.

Generally, vacuum cleaners are classified into dry vacuum cleaners, wet vacuum cleaners, and dry and wet vacuum cleaners.

The dry vacuum cleaner is a vacuum cleaner with a filter to filter out dust and does not inhale water, and the wet vacuum cleaner sucks out washing liquid and water, or sprays and inhales water, and has a separator to separate water and air. It is a cleaner. Dry and wet vacuum cleaners have two functions:

The construction of the dry vacuum cleaner is shown in FIG. As shown in the drawing, the head part 2 for sucking dust on the floor and carpet is made of wheels and squeegee (rubber plate) and the like, and a suction pipe 3 connecting the head part 2 and the main body 1 to each other. And a suction part (7), (8), and (9) which give suction force to the filter part (5), (6), (10) which catch dust and other dry dirt, and the vacuum cleaner head part (2). It is.

In the figure, 4 is an inlet, 5 is a paper filter, 6 is a dust bag, 7 is an inlet, 8 is an outlet, 9 is an exhaust port, 10 is an electrostatic filter, and 11 is a motor.

The dry vacuum cleaner as described above creates a vacuum in the cleaner when the motor 11 is operated to inhale and filter out dust and dirt using a pressure difference between the atmosphere and the cleaner.

Specifically, the squeegee 13, which is a rubber plate, is attached to increase the pressure difference with the atmospheric pressure in the suction nozzle 12 of the head 2, and to use the floor to some extent.

The dust and dirt sucked by the suction nozzle 12 go to the suction port 4 through the suction pipe 3, and most of the dust and dirt are filtered out of the paper filter 5. The fine dust not filtered out is filtered out of the dust collecting bag 6 made of cloth.

Then, the fine dust which passed the motor inlet 7 and passed through the motor 11 and the motor outlet 8 is cleaned by discharging the relatively clean air filtered out of the electrostatic filter 10 in the third order. Is done. Dry vacuum cleaners as described above are in principle incapable of inhaling water from the bottom and do not have a function of cleaning dirt attached to the floor.

One embodiment of the wet vacuum cleaner includes a cleaning head portion consisting of a cleaning head 22 and a suction pipe 23, a suction port 24, a suction passage and a deflection plate 25, as shown in FIGS. 2 and 3. ), A motor section consisting of water consisting of a recovery tank 26, an air separation section, a motor intake port 27, a motor 21, and a motor outlet port 28.

Operation of the wet vacuum cleaner as described above is as follows.

When there is water on the floor, when the motor 21 is operated, a suction force is generated in the cleaning head 22, and water is sucked together with water. The sucked water and air enter the suction port 24 through the suction pipe 23, and the water hits the suction path and the deflection plate 25 so that heavy water falls on the recovery tank 26 and air passes through the motor suction port 27. Discharged through the motor 21 to the motor outlet (28).

The wet vacuum cleaner as described above only sucks without spraying water, so the floor cleaning is not effective and the dry vacuum cleaner does not have a dry filter. In addition, even when water and air are separated, the intake port of the motor is exposed to the recovery tank as it is, so there is a high risk of water entering the motor.

In addition, another embodiment of the wet vacuum cleaner is composed of a cleaning head portion, water, an air separation portion, a washing liquid supply portion, and a motor portion, as shown in FIG. 4, and the cleaning head portion is a cleaning head 32 and a suction pipe 33. As shown in FIG. ), The water and air separation unit comprises an intake port 34, a suction passage and a deflection plate 35, and a recovery tank 36, and the tax solution supply unit is a pump 37, a tax solution pipe 38, a tax discharge pipe 39 and the liquid jet nozzle 40, the motor portion comprises a motor suction port 41, a motor 31, a motor discharge port 42. The operation is as follows.

When the pump 37 is operated, the washing liquid 43 is sucked through the washing liquid pipe 38, and is sprayed toward the cleaning head 32 through the washing liquid discharge pipe 39 to the washing liquid spray nozzle 40.

At this time, when the motor 31 is operated, a suction force is generated in the cleaning head 32 to suck water and air. The sucked water and air reach the suction port 34 through the suction pipe 33, and the water collides with the deflection plate while passing through the suction passage and the deflection plate 35 so that the water is collected in the recovery tank 36. It goes to the motor suction opening 41. Air entering the motor suction port 41 is discharged to the motor discharge port 42 via the motor 31.

Looking at the problem, such a wet vacuum cleaner has a disadvantage in that the performance is poor when cleaning the contaminated floor, water, air separation when the risk of going to the motor, and can not be used dry.

On the other hand, as an example of a dry and wet vacuum cleaner is known in the United States Patent (USP4,218,805), this dry / wet cleaner VAX has a head part that sucks dust and dirt when first used as a dry, and filters dust and dirt The main part has a filter part, and there is a motor which generates suction force.

When wet, there is a head section that sucks water, dust and dirt, and a washing tank that supplies water to the head section.It separates the sucked dust, water, and dirt from the air to store dust, water, dirt, and air. There is a separator (storage) which is sent to the system, which consists of a deflector and a reservoir. And there is a motor unit for generating a suction force.

FIG. 5 is an external view of VAX, and FIG. 6 is a sectional view taken along line A-A of FIG. 5, and when the VAX is used dry, its basic structure and operation principle are the same as those of the dry cleaner of FIG. However, when used in wet, remove the dust bag and the other filter portion connected to the suction port 57 of FIG. 6, put the washing tank 52 in the separation tank 53, wet and switch to use. 51 is a motor. FIG. 6 is a wet shape. In the operation of the wet VAX, when the motor 51 is operated, a part of the exhaust air of the motor is sent to the washing liquid 54 in the washing tank 52 to apply pressure to pump the washing liquid. The water pumped from the washing tank 52 is sprayed to the bottom from the washing liquid spray nozzle 59 of the head 60 through the washing liquid discharge pipe 58. The sprayed water is mixed with dust and dirt, sucked from the head, passed through the suction port 57, and hit the deflection plate 61 to separate air from water, dust and dirt. The separated dust and water and dirt are stored in the separation tank 53, the air passes through the space consisting of the cone-shaped wall 55, enters the motor 51 and is discharged to the motor impeller 56, part of the washing tank ( 52 is released to the atmosphere while acting as a pressure.

The above-mentioned dry / wet cleaner VAX has a good performance in cleaning carpets, but the cleaning performance of floor coverings and floors is poor, and the splashed contaminated water cannot be effectively prevented from frying of the sucked liquid in the separation tank 53. There is a problem that the motor 51 is discharged to the room. An embodiment of a convertible wet and dry vacuum cleaner (CPO245873) of the prior art is shown in FIGS. 7, 8 and 9. For this embodiment, the construction when used in the dry type will first be described. As shown in FIG. 7, 9, the cleaning head 85, the cleaning head part which consists of the suction pipe 87, the dust suction part which consists of the suction opening 78, and the dust collecting bag 73, and the motor suction opening 72 are shown. And a motor unit comprising a motor 71 and a motor discharge port 80. In the wet type, the structure is changed. As shown in FIGS. 8 and 9, the cleaning head portion including the cleaning head 85, the suction pipe 87, the liquid injection nozzle 86, and the liquid intermittent handle 88 is shown. And a water inlet 78, a suction passage 82, an upper lid 79, a recovery tank 84, an inlet connecting pipe and a filter 83, an air separation unit, a connecting port 77, and a washing tube ( 76, a pump liquid supply part consisting of a pump 75, a liquid discharge pipe 74, and a motor part composed of a motor suction port 72, a motor 71, and a motor discharge port 80. The following describes the operation of each configuration and the operation of mutual conversion.

In the dry type, suction force is generated when the motor 71 is operated, and air and dust are sucked into the cleaning head 85. The sucked air and dust passes through the suction pipe 87 to reach the suction port 78 and passes through the dust collecting bag 73.

At this time, the dust is filtered by the dust collecting bag 73 and the air is discharged out through the motor inlet 72 through the motor 71, the motor outlet (80) (7, 9 degrees).

On the other hand, in the wet type, when the pump 75 is operated, the tax solution 81 is in the tax solution tube 76 via the connection port 77, and then goes out to the cleaning head through the tax solution discharge tube 74. The tax liquid 81 which has passed through the tax liquid discharge pipe 74 is injected toward the cleaning head 85 through the tax liquid injection nozzle 86 by operating the tax liquid intermittent knob 88.

At this time, when the motor 71 is operated, suction force is generated in the cleaning head 85, and the jetted tax solution, air and dust are mixed and sucked. The suctioned liquor, air and dust pass through the suction pipe 87 to reach the suction port 78 and again pass through the suction passage 82 to hit the upper lid 79. Here, the relatively heavy tax solution 81 collects in the recovery tank 84 and the air reaches the motor inlet 72 through the inlet connector and the filter 83. From here, air escapes through the motor 71 through the motor 71 as in the dry type (8, 9 degrees).

In addition, when looking at the conversion process from dry to wet and wet to dry, it can be seen that the structure is first converted by a combination of three parts. That is, it consists of a washing tank part for storing the tax solution, a separator tank part for storing the dirty tax solution, a dry filter part consisting of a dust collecting bag, a motor part and a pump part, and are equipped with a separating tank part and a dry filter part. It is divided into base parts having suitable connection devices.

When the wet and dry vacuum cleaners as described above are changed from dry to wet, the upper lid 79 is opened in FIG. 7, and then the dust collecting bag 73 is removed and the separator is inserted into the suction passage 82 and the suction port ( Match the position of 78).

If you want to change from wet to dog, you can reverse it.

Hereinafter, the problems of the wet and dry vacuum cleaner as described above are as follows.

Wet and dry vacuum cleaners as described above are wet and dry vacuum cleaners that are compatible with wet and dry, equipped with a dust collecting bag for dry cleaning, and separates the dust collecting bag for wet cleaning. It is not only cumbersome, but also has a disadvantage of deteriorating the ability to wash the floor after spraying water, and also, it was not possible to inhale water during dry use, and especially when used dry, due to structural limitations. There is a defect that the filtering function is significantly lower than the conventional dry cleaner.

In the case of using a wet vacuum cleaner and a wet and dry vacuum cleaner in a wet manner, when only the dry dust is sucked in without cleaning the water during the cleaning operation, the dry dust cannot be properly filtered like the dry vacuum cleaner. Air pollutants, especially when wet and dry vacuum cleaners are used wet, not only are they less capable of filtering dust than wet vacuum cleaners due to structural problems, but also the contaminants sucked into the cleaner body are rotted by moisture. Odor was generated, there was a disadvantage that the bacteria are breeding, in order to prevent such a phenomenon there were a number of problems such as the need to replace the filter from time to time.

An object of the present invention is to provide a wet and dry vacuum cleaner capable of dry cleaning and water cleaning does not have the conventional problems as described above. Another object of the present invention is to dry and suction dry dust without changing the structure of the water on the floor and the floor can be washed, and dry cleaning and water cleaning so that you can only suck the dry dust while cleaning the water wet It is possible to provide a wet and dry vacuum cleaner.

On the other hand, as shown in Figure 12 and 13, the recovery tank constituting the vacuum cleaner main body (A) and the recovery tank 202 formed on one side of the intermediate partition 201 inside the body 200, and A lid 203 that is openly fixed to the upper portion of the recovery tank 202, a suction port 205 formed in the interior of the recovery tank 202 and having a deflection plate 204 formed at an inner end thereof, and the intermediate partition 201. It is composed of a substantially N-shaped outlet 207 connected to the dust collecting filter chamber 206 through, and a float 208 inserted into the outlet 207 to be elevated according to the level of the tax liquid.

The tax treatment unit is formed on one side of the recovery tank 202, the cleaning tank 210 to store the tax solution, and the tax solution of the tax solution 210 through the liquid discharge pipe 211 (shown in Figure 10) cleaning head It consists of the pump 212 supplied to the washing liquid injection nozzle 106 of (A).

The filter unit is mounted on the dust collecting filter chamber 206 of the body 200 and the dust collecting filter bag 220 for primary filtering the intake air discharged from the outlet 207, and a constant on one side of the dust collecting filter chamber 206 Motor protection filter 223 slidably installed on the guide 222 of the support plate 221 formed at intervals, and guide protrusions 224 formed on the other side of the support plate 221 to support the motor 230. ) And the motor vibration preventing member 225 interposed between the guide protrusion 224 and the motor 230 to reduce vibration of the motor 230, and are installed on a predetermined portion of the upper surface of the body 200 to have fine dust. It is composed of a fine dust removal filter 226 for filtering.

The motor unit is composed of a motor 230 supported by the guide protrusion 224 and the support partition 227 of the support plate 221 as described above, the motor 230 is preferably used as a wet motor.

Meanwhile, as shown in FIGS. 15 and 16, the dehumidifying part is fixed to a dehumidifying case 240 in a rectangular box, in which a normal dehumidifying agent (not shown) is mounted on both sides of the bottom of the dust collecting filter chamber 206, respectively. The hinge grooves 241 and 241 'formed on both sides of the upper surface of the dehumidifying case 240 are coupled to both hinge protrusions 243 and 243' of the lid 242 so as to be rotatable and open. In addition, the lid 242 is formed with a through hole 244 for removing moisture, and a handle 245 for smoothly opening / closing is formed on one side edge of the upper surface, and the middle portion of the inner wall of the dehumidifier case 240. And the middle portion of one side of the lid 242 is configured to prevent the phenomenon that the locking groove 246 and the locking projection 247 as the locking means are respectively formed to rotate the lid 242 arbitrarily.

Wet dry vacuum cleaner according to an embodiment of the present invention as described above is to be used in wet as well as dry without changing the structure, the operation of which will be described as follows First, the cleaner body (B) When the wet motor 230 is operated, a vacuum pressure is generated in the front and rear suction nozzles (02) 103 of the cleaning head (A). At this time, when the vacuum cleaner is used in dry form, that is, when water is not used, the front and rear suction nozzles 102 and 103 allow dry dust and other solids to be sucked into the cleaner body A through the suction pipe 101. Among the solids sucked into the cleaner body A, a relatively large weight is stored at the bottom of the recovery tank 202, and most of the dry dust is discharged through the discharge port 207, and then filtered by the dust collecting filter bag 220. The fine dust that passes through the motor protection filter 223 and the motor fan is filtered by the fine dust removal filter 226 to discharge the purified air to the outside of the body 200.

On the other hand, when the vacuum cleaner is used in a wet manner, that is, when cleaning with water, when the pump 212 of the tax treatment unit under the control of the control circuit unit is operated, the tax solution of the tax solution tank 210 is the liquid discharge tube 211 It is supplied to the washing liquid injection nozzle 106 of the cleaning head (A) through.

In this state, when the worker moves the cleaning head A in the main work progress direction, first, the front suction nozzle 102 acts as a broom for sucking dry dust. It is to be sprayed on the bottom surface, it is possible to clean the water to replace the mop by the strip brush 107.

On the other hand, the washing liquid soiled by the rear suction nozzle 103 at the rear thereof is sucked together with the air. If the cleaning head A is moved in a direction opposite to the main working progress direction, the separation roles of the rear suction nozzle 103 and the front suction nozzle 102 are reversed. Detailed description will be omitted.

In this way, the contaminant washing liquid and other contaminants sucked through the suction pipe 101 through the suction port 205 and into the cleaning body B are hit by the deflection plate 204 of the suction port 205 and the air and water and the like are collected in the recovery tank 202. The air is separated into contaminants, and thus air is guided to the dust collecting filter bag 220 through the discharge port 207, and the contaminated washing solution and other contaminants having a certain weight are stored at the bottom of the recovery tank 202.

At this time, the dust introduced with the air through the outlet 207 without being mixed with water is filtered through the dust collecting bag 220 and the fine dust removal filter 226. When the water level in the recovery tank 202 rises by such an operation, the float 208 rises and the discharge port 207 is blocked by the float 208 at the full water level.

In the wet vacuum cleaner as described above, the dust introduced with the air through the outlet 207 without being mixed with water is first filtered by the dust collecting filter bag 220. Moisture is removed by the dehumidifying agent of the dehumidifying case 240 fixed to the bottom of the dust collecting filter chamber 206 because it does not mix with the water to some extent, but the dust is collected by keeping the dust collecting bag 220 always dry It is possible to prevent the contamination of the contaminants caught in the filter bag 220, and thus to significantly extend the replacement cycle of the dust collecting filter bag 220.

17a and 17b is a longitudinal sectional view and a bottom view showing another embodiment of the wet-type vacuum cleaner cleaning head A according to the present invention, respectively, as shown in the lower portion of the head body 110 The front and rear suction nozzles 111 and rear suction nozzles 121 are formed, suction passages 111 'and 112' are formed on the upper side thereof, and partitions 113 are formed in the middle part. In addition, the partition 113 is a coupling portion 113a is connected to the washing liquid injection nozzle 114, the washing liquid injection nozzle 114 is the pump 212 of the cleaning body (B) by the liquid discharge pipe 116 )

In addition, a brush 119 is rotatably coupled to a lower portion of the partition 113, and a motor 118 for rotating the brush 119 is installed at an upper side thereof. The motor 118 and the brush 119 are provided. The pulleys 120 and 121 of the belt 122 is connected to the power of the motor 118 is to be transmitted to the brush 119.

In addition, a wheel 123 is provided at a lower edge portion of the head body 110, and a through hole 110a is formed at a side wall of the head body 110. In addition, the suction pipe 115 is connected to the rear of the head body 110, the suction pipe 117 is connected to the suction port 205 of the cleaning base (B) by the suction hose 117.

Looking at the operation of another embodiment of the cleaning head of the present invention as described above is as follows.

First, when the pump 212 in the liquid treatment unit of the cleaning body (A) is operated, water (the liquid) is sprayed to the bottom from the injection nozzle 114 through the liquid discharge pipe 116, and at the same time the head motor 118 Brush 119 is rotated by the operation of) to peel off the contaminants stuck to the floor. At this time, if the cleaning head A is moved forward, dry dust is sucked from the front suction nozzle 111, and the rear suction nozzle. At 112, water and contaminants adhering to the bottom are sucked in, and are sucked into the recovery tank 202 of the cleaning body B through the suction pipe 117 through the head suction pipe 115.

At this time, the front suction nozzle 111 and the rear suction nozzle 112 is immediately recovered to the recovery tank 202 without the congestion of the sucked liquor and contaminants during operation in the head suction pipe 115 and the suction hose 117. Basically, the degree of vacuum should be maintained while maintaining the air volume basically.

Therefore, the amount of suction at the bottom can be effectively sucked up by the sufficient vacuum degree, i.e., the pressure difference. In addition, the width of the front and rear suction nozzles 111 and 112 decreases the suction force of the entire system in order to increase the rising speed (suction input) at the bottom (bottom) of the suction nozzles 111 and 112. It is desirable to keep it as small as possible within the range which does not matter.

Then, when the cleaning head (A) is moved to the rear, the rear suction nozzle (112) sucks dry dust, the front suction nozzle (111) sucks the washing liquid (water) and the contaminants peeled off the floor. Since the effect of the cleaning head (A) according to the present invention is designed for carpets, the existing dry / wet vacuum cleaners could not be expected to have a cleaning effect on floors, namely, floorboards, folkboards, and monolium floorboards. The cleaning head A is very excellent in cleaning performance by the brush 119, and by appropriately selecting the hair of the brush 119, the floor can be sufficiently prevented from being damaged.

In addition, since the suction nozzles 111 and 112 are forward and backward, the suction can be effectively carried out, and the cleaning head A has the same suction and cleaning effect even when the cleaning head A moves forward or backward. In addition, by sucking the dry dust, in particular the hair in the suction nozzles 111 and 112 in the advancing direction can prevent the phenomenon that the hair is wound on the brush 119.

In addition, in order to keep the rotating part of the brush 119 at atmospheric pressure, a plurality of through holes 111a are formed on the wall surface of the head body 110 to remove the sucker effect that the sheet is stuck to the cleaning head A. have.

As described above, the wet and dry vacuum cleaner according to the present invention is a wet and dry vacuum cleaner having a function of washing while supplying the washing solution to the floor, unlike conventional wet and dry conversion vacuum cleaners, and dry dry without changing the structure. It is possible to inhale dust and to insert water on the floor and to wash the floor, and to wet dry dust while wet cleaning.

Therefore, by utilizing only the advantages of dry, wet, wet and dry conversion vacuum cleaner, not only dry dust can be filtered like dry cleaner, but also water can be cleaned like wet, wet and dry vacuum cleaner, and cleaned by brushing action. There is an effect of improving the efficiency.

In addition, by installing a dehumidifier case equipped with at least one dehumidifying agent in the dust collecting filter chamber to remove the moisture in the dust collecting filter bag, it is possible to prevent the contaminants of the dust collecting filter bag from decaying due to moisture, and thus the dust collecting filter bag It is effective in eliminating the hassle that needs to be exchanged at any time.
