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

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

Here, 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 is a suction tank for sucking or spraying water and spraying water. That 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 composed of a wheel and a 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 state inside the cleaner when the motor 11 operates to suck and filter dust and dirt using the 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 and discharged to purify relatively clean air. 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 a wet vacuum cleaner includes a cleaning head portion consisting of a cleaning head 22, a suction pipe 23, a suction port 24, a suction passage and a deflection plate 25, as shown in FIGS. ), 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 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).

Since the wet vacuum cleaner as described above only sucks without spraying water, 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 recovery tank motor inlet is exposed 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. ), 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. Go to the motor suction port 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, 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 United States Patent (USP4,218,805), this dry / wet cleaner VAX has a head part that sucks dust and dirt when first used dry, and filters out 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 motor 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, 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 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.

An embodiment of a convertible wet and dry vacuum cleaner (CP0245873) of the prior art is shown in FIGS. 7, 8 and 9. For this embodiment, a configuration when used in the dry type will first be described. As shown in FIG. 7, FIG. 9, the cleaning head 85 which consists of the cleaning head 85, the suction pipe 87, the dust removal part which consists of the suction opening 78, and the dust collecting bag 73, and the motor suction opening 72 is shown. And a motor unit comprising a motor 71 and a motor discharge port 80. In wet type, the structure is changed. As shown in FIGS. 8 and 9, the cleaning head portion includes a cleaning head 85, a suction pipe 87, a liquid injection nozzle 86, and a liquid intermittent handle 88. 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 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 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 changed 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 separation tank 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 compatible vacuum cleaners are equipped with a dust collecting bag when dry cleaning, and when the wet cleaning is used to separate the dust collecting bag, the replacement work is 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.

As described above, the motor unit includes a motor 230 supported by the guide protrusion 224 and the support partition wall 227 of the support plate 221, and 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, the operation of which 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 through the discharge port 207, and then filtered by the dust 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 100 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, and the tax solution from the tax jet nozzle 106 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 plate 204 of the suction port 205 and the air and water in the recovery tank 202. The air is separated into other 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 to block the outlet 207 by the float 208 at the full water level.

15a and 15b is a longitudinal cross-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 Front and rear suction nozzles 111 and rear suction nozzles 121 are formed, suction passages 111 'and 112' are formed on the upper side, and a partition 113 is formed in the middle portion. The liquid injection nozzle 114 is connected to the engaging portion 113a of the partition 113, and the liquid injection nozzle 114 is connected to the pump of the cleaning body B by the liquid discharge pipe 116. 212).

In addition, a brush 119 is rotatably coupled to a lower portion of the partition l13, and a motor 118 for rotating the brush 115 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 By the operation of the brush 119 is rotated, the contaminants stuck to the floor is peeled off 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), water and the contaminants attached to the bottom is sucked from the rear suction nozzle (112), the suction hose 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, and the front suction nozzle 111 sucks the washing liquid (water) and the contaminants separated from the bottom.

Since the effect of the cleaning head (A) according to the present invention as described above is mainly designed for carpets, the cleaning effect could not be expected on the floor, namely, floorboards, folkboards and monolium floorboards. The cleaning head A of the example is very excellent in washing performance by the brush 119, and the floor 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 maintain the rotating portion of the brush 119 in the atmospheric pressure state by forming a plurality of through holes (111a) on the wall surface of the head body 110 can 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 suck water on the floor and to wash the floor, and to wet only the dry dust while wet cleaning the water.

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 cleaning efficiency by brushing action. There is an effect such as to improve.
