The present invention relates to a wet and dry vacuum cleaner, and more particularly, to remove the recovery tax of the wet and dry vacuum cleaner, which is installed to detachably remove the disposable recovery tax storage pack in which the recovery tax solution is stored. Relates to a device.

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. It consists of a filter part (5), (6), (10) for filtering dust and other dry dirt and suction parts (7), (8), (9) for giving suction power to the cleaner head (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 very fine dust that has passed through the motor inlet 7 and passed through the motor 11 and the motor outlet 8 is filtered out of the electrostatic filter 10 in order to discharge the purified clean air and discharged. 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 washing dirt (floor) adhering 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 inlet 27, a motor 21, and a motor outlet 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 so that water and air are sucked together. The sucked water and air enter the suction port 24 through the suction pipe 23, and the water hits the suction passage 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 floor cleaning is not effective and there is no dry filter because it 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 moisture 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. ), 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 and the air is supplied to the motor. It goes to the suction port 41. Air entering the motor suction port 41 is discharged to the motor discharge port 42 via the motor 31.

The problem is that wet vacuum cleaners like this have a poor performance when cleaning contaminated floors. When water and air separation, the risk of water going to the motor, there is a disadvantage that can not be used dry.

On the other hand, as an example of a dry and wet vacuum cleaner is known in the US patent (USP4,218,805), this dry / wet vacuum cleaner VAX has a head part that sucks dust and dirt when first used dry, and filters dust and dirt The main filter is a filter unit, and there is a motor that 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 and put the washing tank 52 in the separation tank 53 is used to convert to wet. 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 to be sucked from the head and passed through the suction port 57 to hit the deflection plate 61 to separate the air from the water, dust and dirt. The separated first and water and dirt is 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 floorboards and floors is poor, and the splashed contaminated water cannot be effectively prevented from frying of the liquid sucked from the separation tank 53. There is a problem that the motor 51 is discharged to the room.

And one embodiment of the prior art convertible wet and dry vacuum cleaner (CPO245873) is shown in FIGS. 7, 8 and 9. In the first embodiment, the construction when used in the dry type will be described. As shown in Figs. 7 and 9, the cleaning head portion, the suction port 78, and the dust collecting bag made up of the cleaning head 85 and the suction pipe 87 will be described. It consists of the dust removal part which consists of 73, and the motor part which consists of the motor suction opening 72, the motor 71, and the motor discharge opening 80. As shown in FIG. 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 75, and a tax solution supply part composed of the tax liquid discharge pipe 74, and a motor part composed of the motor suction port 72, the motor 71, and the 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 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 75, and then 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 to the motor outlet 80 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 dry, just 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 the wet vacuum cleaner and the wet and dry vacuum cleaner in the wet mode, when only the dry dust is sucked in without cleaning the water during the cleaning operation, the dry air cannot be properly filtered like the dry vacuum cleaner. In particular, when wet and dry vacuum cleaners are used in a wet manner, there are various problems such as the ability to filter dust due to structural problems being lower than that of a wet vacuum cleaner.

In order to solve the above problems, the applicant has been filed with the application of “wet and dry vacuum cleaner capable of dry cleaning and water cleaning” (Patent Application No. 90-22448) on December 29, 1990. Referring to the drawings as follows.

As shown in FIG. 10 and FIG. 11, the cleaning head (A) for spraying the cleaning solution by cleaning with a brush and suctioning the dirty cleaning solution, a recovery tank for storing contaminants and separating water and air, and storing the tax solution A main body (B) consisting of a washing liquid treatment unit having a washing liquid tank and a pump for supplying water to the injection nozzle of the cleaning head, a filter portion for filtering out discharge air, and a motor portion as a suction source.

An embodiment of the cleaning head A will be described with reference to FIG. 14. At the bottom of the head body 100 connected to the suction pipe 101 to the body B, the front suction nozzle 102 is spaced at a predetermined interval. And rear suction nozzles 103 are formed to communicate with each other, and maintain the degree of vacuum inside the front and rear suction nozzles 102 and 103 at the front and rear of the front and rear suction nozzles 102 and 103. In addition, the squeegee 104, 105 for collecting the dirt and the like are provided respectively.

In the middle portion of the front and rear suction nozzles 102 and 103, a washing liquid injection nozzle 106 is formed from an upper side, and a strip brush is disposed at both ends of the lower portion of the washing liquid injection nozzle 106 at predetermined intervals. 107 is fixed.

In addition, wheels 108 and 109 are respectively provided on the front and rear surfaces of the lower surface of the cleaning head A to facilitate the movement of the head cleaning A more smoothly.

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 washing 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.

Wet dry vacuum cleaner according to an embodiment of the present invention as described above is to be used as a wet as well as dry without changing the structure, it will be described as follows.

First, when the wet motor 230 of the cleaner body B operates, vacuum pressure is generated in the front and rear suction nozzles 102 and 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 to the discharge port 207, and then filtered through the current collecting filter bag 220. The fine dust emitted 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.

As such, the contaminated washing solution and other contaminants sucked into the cleaning body B through the suction port 205 through the suction pipe 101 are hit by the deflection pipe 204 of the suction port 205 and the air, water, and the like 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.

15a and 15b 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 liquid jet nozzle 114 is connected to the coupling part 113a of the partition 113, and the liquid jet nozzle 114 is pump 212 of the cleaning body B by the liquid jet 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 (A) as described above, first operating the pump 212 in the cleaning treatment part of the cleaning body (A), the water (washing liquid) is injected through the liquid discharge pipe 116 ( Sprayed to the floor in the 114, at the same time the brush 119 is rotated by the operation of the head motor 118, to remove the contaminants stuck to the floor and the floor.

At this time, when the cleaning head (A) is moved to the front, dry dust is sucked from the front suction nozzle (111), the back suction nozzle (112) is sucked contaminants adhering to the water and the floor is sucked through the head suction pipe 115, It is sucked into the recovery tank 202 of the cleaning body B through 117.

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 suction speed becomes very large due to sufficient vacuum degree, i.e., the pressure difference, so that the washing liquid at the bottom can be sucked effectively.

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.

The effect of the cleaning head (A) in this way was that the conventional dry / wet vacuum cleaner was mainly designed for the carpet, it could not be expected to clean the floor, such as floorboards, folkboards, monolium floorboards, etc., but by the brush (119) The performance is very excellent, and damage to the bottom can be sufficiently prevented by appropriately selecting the hair of the brush 119.

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, thereby eliminating the scaffolding effect that the sheet is stuck to the cleaning head A. have.

As described above, the wet and dry vacuum cleaner is a wet and dry vacuum cleaner having a function of cleaning while supplying the washing liquid to the floor, unlike the conventional wet and dry conversion vacuum cleaner, inhaling dry dust on the floor without changing the structure. It is possible to inhale the water and wash the floor, and it is also possible to suck only dry dust during the wet cleaning.

Therefore, by utilizing only the advantages of dry, wet, wet and dry conversion vacuum cleaner, it is possible to filter dry dust like a dry vacuum cleaner and to clean water like wet, wet and dry vacuum cleaners, and cleaning efficiency by brushing action. There is an effect such as to improve.

However, the wet-dry vacuum cleaner as previously described by the present applicant separates the suction port 205 from the cleaner body 200 when removing the recovery tax solution stored in the bottom of the recovery tank 202, There is a hassle to remove the recovery tax liquid by lifting the body 200 upside down, which is a serious inconvenience when the operator is not familiar, even if the removal of the recovery tax solution, the contaminants at the edge of the bottom of the recovery tank 202 Since the cleaning work is not easy because it is put on, as it is left as it is, there is a problem that the residual contaminants decay, odors are generated, bacteria grow.

The main object of the present invention is to provide a recovery and washing liquid removal device of the wet-type vacuum cleaner does not have the problems as described above.

Another object of the present invention is a wet-dry vacuum that makes it easier to remove the recovered tax liquid by disposing only the recovered tax liquid storage pack in which the recovered tax liquid is stored when the amount of the recovered tax liquid is above the reference level or the cleaning operation is completed.

Referring to the operation and effect of the recovery tax removal device of the wet-type vacuum cleaner according to the present invention configured as described above are as follows.

First, when the pump 407 of the cleaner body B 'is operated, the washing liquid of the washing liquid tank 406 is sprayed to the floor from the washing liquid spray nozzle 312 of the cleaning head A' through the washing liquid discharge pipe. The rotary brush 307 is rotated by the driving of the head motor 309 to peel off the contaminants stuck to the floor from the floor.

At this time, when the cleaning head (A ') is moved forward, the dry dust is sucked from the front suction nozzle 302, the contaminants attached to the water and the bottom is sucked through the suction pipe 301 in the rear suction nozzle 303, It enters into the collection tank 402 of the cleaner body B '.

In addition, when the cleaning head A 'is moved backward, the roles of the front and rear suction nozzles 302 and 303 are changed, so that the dry dust is sucked from the rear suction nozzle 303, and the water is sucked from the front suction nozzle 302. And contaminants adhering to the floor are inhaled.

As described above, the dry dust and the contaminated washing liquid and the contaminants sucked into the recovery tank 402 of the cleaner body B 'through the suction port 405 are formed in the shape of the deflection plate 404 of the suction port 405, and the recovery tank ( Due to the enlarged space effect of 402, the liquid taxable liquid and the pollutant having a predetermined weight are separated from the ideal flow and stored in the bottom of the recovery tank 402 by the density difference with respect to gravity.

At this time, since the recovery tax storage pack 413 having a predetermined shape is detachably attached to the bottom of the recovery tank 402, the contaminated tax solution and the contaminants are stored in the recovery tax storage pack 413.

At the same time, the remaining air is sucked into the paper filter 411 through the outlet 408 due to the vacuum pressure generated by the driving of the motor 402.

At this time, since the fluid passing through the motor 402 may include excessive moisture, it is preferable to use a wet motor.

On the other hand, the wet dry vacuum cleaner according to the present invention as described above can be used as a wet and dry vacuum cleaner without a separate structure bar, in the case of dry cleaning, the relatively heavy weight of contaminants such as glass, paper storage tax storage The pack 413 is stored, the dust is sucked through the outlet 408 is filtered by the paper filter 411, in the case of the wet cleaning, the contaminated washing solution and contaminants are recovered tax storage pack ( 413).

In this way, when the cleaning operation is completed or when the recovery tax liquid is removed when all the tax solution of the tax bath 406 is used, first, the recovery tank lid 403 is opened, and then the recovery tax solution pack 413 is recovered. 402 is separated and disposed of, and when the adhesive 420 is adhered to the intermediate tube 419, the upper part of the recovery tax storage pack 413 is held inward to adhere to the adhesive 420. The recovery tax storage pack 413 may be discarded while the recovery tax liquid is not allowed to flow down.

In addition, when the new recovery tax storage pack 413 is coupled to the recovery tank 402, the catching hole 416 or the locking piece (416) of the recovery tax storage pack 413 in the locking projection 414 of the recovery tank 402 418 may be combined to secure the recovery tax storage pack 413 by engaging, the separation operation may be performed in the reverse order of the coupling.

The recovery tax liquid removal device of the wet-type vacuum cleaner according to the present invention as described in detail above is provided with a single-use recovery tax storage pack inside the recovery tank to more easily remove the recovery tax liquid, and at the same time to remove the recovery tax liquid. Since the inside of the tank is cleanly cleaned, there is no need to clean the recovery tank separately, and there is an effect of maintaining a pleasant environment at all times by preventing the phenomenon of residual pollutants or odors from occurring.
