Description

Vacuum wet mop brush for floor cleaning}

The present invention relates to a brush for cleaning the floor of a vacuum cleaner, and more particularly, in cleaning the floor, dust and foreign matter on the floor are vacuumed and removed with a vacuum brush, and then cleaning is performed twice, such as additional wet wiping. It is about a vacuum wet mop cleaning brush that easily finishes high-quality dust cleaning and wet mop cleaning at once with only the effort of dust cleaning what needs to be done, and there is no mop washing.

In the case of cleaning the indoor floor, dust is first removed with a vacuum brush and then additionally cleaned with a wet mop, or a rotating plate to which a wet mop can be attached to one side of the bottom of the dust brush is provided. A rotational force is obtained by an electric motor, and a technique of simultaneously wiping the floor with a rotating wet mop while sucking dust from the front is also known.

In addition, the technology of Patent No. 10-0618646 filed by the present inventor is provided with a device capable of supplying water to the cleaning floor, so that the water supplied to the cleaning floor washes dust and dirt on the floor and is sucked into the cleaner body by vacuum. / is removed, using water with two rows of protruding wipers (similar to car windshield wipers) provided at the front and rear borders of the brush inlet in the horizontal direction and spaced apart at a certain distance to scrub the floor and remove floor moisture Brushes for vacuum cleaners and mopping are also known.

However, in floor cleaning, it can be said that cleaning is satisfactory only when it is properly cleaned with a high degree of completeness. In the case of the known technology of attaching a wet mop to the rotary plate of a dust brush, replacing the wet mop in the middle of floor cleaning and washing the mop There was this accompanying inconvenience, and the actual cleaning condition was not satisfactory.

In addition, in Patent No. 10-0618646 filed by the present inventor, the vacuum cleaner and water cleaning brush using water effectively removes fine dust from the floor by providing a floor dust inlet at an arbitrary location on the brush body instead of being formed on a wiper blade in contact with the floor. The problem of not being able to remove it well, and when cleaning the floor repeatedly by moving forward and backward, there were many complaints from workers because it required a lot of force to improve the cleaning condition, and when it was light with little force, a lot of moisture remained and the cleaning condition deteriorated. As a result of this phenomenon, we were facing a technical limit that could not satisfy both the power required and the degree of completeness of cleaning.

The present invention is to solve the above problems, in particular, to solve the technical problems of a vacuum cleaner using water and a water cleaning brush of Patent No. 10-0618646 to implement a light yet satisfactory cleaning state,

An object of the present invention is to improve the shape of the brush wiper, thereby greatly reducing the friction caused by the contact between the wiper and the bottom surface, and at the same time using the vacuum transmitted from the cleaner body to the bottom surface of the brush to suck air containing dust from the wiper. By lowering the vacuum appropriately, the brush moves forward and backward without difficulty and becomes light, and the wiper that touches the floor immediately sucks in floor dust to remove dust well, and also removes moisture from the floor well by selecting a wiper made of appropriate resilient material. It is to provide a vacuum wet mop cleaning brush that is lightweight and can perform satisfactory cleaning with a high degree of completion.

Another object of the present invention is to change and improve the position and height of the rolling wheel of the brush, so that the pushing force that the operator applies obliquely to the brush for the forward movement of the brush is the synthesis of the force pressing to the floor and the force pushing forward (pull toward the body). When pulling toward the body, the movement of the brush is rather light because there is no force to press it to the floor and the force to lift it up acts, so I will not describe it when pulling it toward the body), all the force to press it to the floor is absorbed by the rolling wheels, and only the force to push forward is applied to the wiper, lightly It is to provide a moving vacuum mopping brush.

As a technical idea to achieve the above object, the present invention, the brush is a body consisting of an upper housing and a lower housing, and a moving pipe; A water supply device for supplying water to the cleaning floor; The water supplied to the floor washes dust, dirt, and the floor and sucks in the dirty water, so that the vacuum transmitted from the cleaner body through the moving pipe reaches the cleaning floor surface, so that it touches the suction passage formed by the lower housing and the upper housing to clean the lower housing. a suction port formed at one end; a pair of wipers protruding toward the floor by being inserted into the grooves of the lower housing and extending horizontally to both ends of the brush at the front and rear boundaries of the suction hole formed in the lower housing of the body; a wheel formed on one end of the bottom surface of the lower housing to enable rolling movement of the brush; It is characterized in that it includes.

According to the vacuum wet mop cleaning brush according to the present invention, dust cleaning and wet mop cleaning are completed in one easy and light one-time operation with only enough effort to clean the indoor floor, and the cleaning completeness is cleaner than hand wipes and does not leave moisture, so it is smooth. It has the advantage of being able to clean the floor with a satisfactory level of completeness.

In addition, in Patent No. 10-0618646, the water-based vacuum cleaner and water cleaning brush technology had the inconvenience of replacing the floor brush with a dust-only brush when only dust cleaning without water was used because the floor brush adhered to the floor. The vacuum wet-mop cleaning brush according to the invention has the advantage of being able to vacuum and wet-mop cleaning at the same time as desired, or to vacuum dust without replacing the brush.

Floor cleaning can be divided into two types: removing dust and dirt from the floor and wiping the floor with a wet mop. In the case of cleaning the floor after only removing dust or dirt with a vacuum cleaner, etc. In some cases, in order to remove fine dust and floor stains or marks adhering to the floor in a state of static electricity, wet mop cleaning is required to complete satisfactory cleaning, but many people skip the difficult and difficult wet mop cleaning and only clean dust. I think we need a means to make it easy to clean with a wet mop.

The vacuum wet mop cleaning brush of the present invention aims to finish both cleaning at once, including the wet mop cleaning of the floor, with only the effort of vacuum dust cleaning to remove floor dust, and even if you want only dust cleaning with a vacuum, the floor It also has the convenience of being able to do it without any problems just by not supplying water to it.

1 and 2 are product perspective views showing a vacuum wet mop cleaning brush according to the present invention.

3, 4 and 5, the vacuum wet mop cleaning brush according to the present invention has a moving pipe at one side of the rear end of the suction passage (A) formed by the upper housing 100 and the lower housing 200 forming the body. 300 is inserted and provided, and the vacuum transmitted from the cleaner body (not shown), the cleaner hose (not shown), and the pipe (not shown) to the moving pipe 300 is connected to the suction passage A and the suction passage ( It proceeds to the suction port (B) formed at the front end of A), and is inserted into the groove 220 of the lower housing 200 and protrudes toward the floor, extending to both ends of the brush in the horizontal direction forming the boundary of the suction port (B) A pair of wipers 210 are in contact with the bottom surface, and the water supply nozzle parts 230 formed between the two wipers at both left and right ends of the pair of wipes 210 protrude higher than the bottom of the brush has been

It is generated from the cleaner body (not shown) on the cleaning floor surface surrounded by the pair of wipers 210 and the water supply nozzle part 230, passes through a hose and a pipe (not shown), and passes through the moving pipe 300 and the suction passage. (A), predetermined cleaning is performed by the vacuum reached through the inlet (B) and the like.

1, 2, 3, 4, 5, 7 and 11, the water supply device (hose) connected to the water tank (not shown) and the water supply valve (not shown) is The brush is inserted through the hole 110 provided at a certain place of the upper housing 100, is developed in contact with the lower housing 200, and is branched left and right at the Tee 410 to form at both inner ends of the lower housing 200. It is connected to the Knob 250 and is connected to the water supply nozzle part 230 formed between the two wipers at both the left and right ends of the pair of wipes 210 on the outside of the lower housing 200 to supply water. However, the water supply nozzle part 230 is formed to protrude from the bottom surface of the lower housing 200, but protrudes about 2.0 mm lower than the protrusion height of the blade of the wiper 210, which reduces the degree to which the wiper bends and lies during cleaning. Considering that, it almost touches the floor, and air and dust are sucked in by vacuum through the gap between the protruding water supply nozzle part 230 and the bottom surface, and the water from the nozzle part moves along with the air. Along the inside partitioned by the brush, it rushes toward the suction port (B) located at the center of the brush while washing the cleaning floor, and the air and dust sucked in between the protrusions on the front wiper dust surface (A) in the latter direction join together It is directly sucked into the cleaner body (not shown) through the suction port (B).

When the water supply valve (not shown) is shut off, the water supply is stopped and water is no longer supplied to the cleaning floor, but the water already on the floor and the suction passage inside the brush (A), inside the moving pipe, In order to suck all the dirty water flowing inside the pipe and hose (not shown) into the cleaner body (not shown), the cleaner needs to be operated for about 2 minutes without stopping.

6, 8, 9, 10 and 11, the cross section of the wipe 210 has a T shape, and the upper part of the letter T is inserted into the groove 220 of the lower housing 200. The lower I-shaped part becomes a blade and stands toward the cleaning floor, and the blade of the wiper 210 rubs and wipes the dust suction surface (hereinafter referred to as the dust surface (A)) and the floor, and removes moisture to clean with a wet rag The two sides play a different role as the side (hereinafter referred to as the mop side (B)), and a protrusion (C) is built at the end of the blade of the dust side (A), spaced at an appropriate distance in the lengthwise direction of the blade, so that a number of The protrusions are erected, and a plurality of protrusions (D) are erected at a certain distance in the longitudinal direction on the mop surface (B), but they are built by retreating inward at a certain distance from the end of the blade.

When cleaning by repeating forward and backward motions of the brush, the blade of the wiper 210 is laid in the opposite direction to the direction in which the brush moves, and the wiper 210 in front of the direction of progress always moves the dust surface (A) to the bottom The wiper 210 at the rear of the moving direction always moves with a wet mop, and the mop surface B is laid down to touch the floor. Therefore, the wiper 210 is inserted into the groove 220 of the lower housing 200 so that the mop surface B faces each other and the dust surface A faces the outside.

In the wiper 210 at the front of the moving direction entering the dust suction stroke, a plurality of protrusions (C) standing at the end of the blade of the dust surface (A) first contact the floor, and the tip of the blade is spaced apart from the floor by the height of the protrusion Since it is floating, the contact between the floor and the dust surface (A) of the wiper is only in contact with the projection, so the contact area is very small and the frictional force is very small even though it is a rubber material with a high friction coefficient.

In the dust surface (A), dust or dirt from the floor is sucked in along with air into the space (hole) formed between the cleaning floor surface and the projections, and dust cleaning is performed. By properly lowering the brush, the brush adheres properly to the floor and the operator's pushing and pulling force is reduced, making it light. On the other hand, the best condition of the floor, which removes floor dust and water well and is smooth, has a contradictory relationship as the strength of the vacuum increases, but it is more important that it is light and not difficult for cleaning workers.

Here, the elements that lighten the brush movement include maintaining an appropriate vacuum by the distance between the projections (C) erected on the wiper dust surface (B) and the height of the projections, and the position and height of the rolling wheel (340) described later in forward motion. There is a wheel that absorbs all the force pressing on the floor, and the vacuum strength and the repulsive elasticity of the wiper material are involved as factors that remove moisture from the floor. Resilience is becoming a more important factor.

Patent No. 10-0618646 prior to improvement of vacuum cleaner and water cleaning brush

The cross-section of the wiper is T-shaped, but it is a flat cross-section (produced by extrusion) with no protrusions on the dust and mop surfaces, so there is no distinction between the dust and mop surfaces, and when the brush moves forward, the dust surface is the wiper As the blade sweeps the floor, a significant amount of floor dust is sucked in under the blade, and other dust is collected on the blade of the wiper and pushed away, and when the brush moves backward, it remains on the floor. There is no dust suction hole (suction hole) to suck in dust and dirt while properly reducing the vacuum on the cleaning floor partitioned by the wiper, so the brush adheres closely to the floor and the power required for cleaning is very large. there was

The wiper 210, which entered the process of cleaning the wet mop at the rear of the moving direction, is laid so that the end of the blade of the mop surface (B) touches the floor, and the end of the blade rubs against the floor to rub and scrape the water to remove all with vacuum. At this time, the rebound elasticity of the wiper material has a great influence on the degree of remaining water, and the tensile strength, abrasion resistance, and flex crack resistance of the material affect the service life of the wiper. It can be easily fitted into the groove with a wiper. Therefore, it should be selected by considering the physical properties of rubber materials, but rubber materials are not covered here.

In addition, even when the direction of brush movement is changed and the direction of movement is reversed, the dust surface (A) and the mop surface (B) of the wiper are the same as described above, and the front wiper in the direction of travel is the dust suction stroke, and the protrusion (C) of the dust surface (A) touches the floor, and the wiper 210 is fitted into the groove 220 of the brush lower housing 200 so that the blade of the mop surface B touches the floor in the wet mop cleaning stroke of the rear wiper. The wiper should be inserted so that the facing side is the mop surface (B) and the outside is the dust surface (A).

Referring to FIGS. 2, 5, and 6, another factor that affects the amount of force required for the moving motion of the brush in the pushing and pulling motion when the cleaning worker cleans is the rolling wheel 240 on the bottom of the brush. However, unlike the water cleaner and water cleaning brush of Patent No. 10-0618646, the two wheels in front of the wiper are gone, and the moving pipe 300 axis 310 One wheel at the front of the shaft is formed close to the shaft 310, each one by one, and a total of three rolling wheels are provided. This is because when the cleaning worker pushes and pulls the brush, especially when the worker pushes forward, the force applied obliquely forward through the handle and the pipe (not shown) is transmitted to the axis 310 of the moving pipe of the brush, and the transmitted When analyzing the force, the point of action becomes the axis 310 of the moving pipe, and consists of a downward pressing force at a right angle of 90 degrees and a force pushing forward horizontally. It is transmitted to the two rolling wheels located behind the moving pipe 300 and the two rolling wheels located in front of the wiper behind the axis 310 of the moving pipe 300, and at the same time, the same is transmitted to the pair of wipers that protrude more than the rolling wheel and touch the floor, so that the wiper moves to the bottom However, in the improved rolling wheel of the present invention, all the pressing forces from the top to the bottom are absorbed by the rolling wheels formed in front and behind the axis 310 line in proximity to the moving pipe axis 310 line, so the two wipers Only the forward pushing force is applied.

Therefore, in the improved rolling wheel, the brush wiper blade sticks to the floor and moves only by the vacuum formed on the bottom surface created by being surrounded by the pair of wipers 210 and the water supply nozzle parts 230 at both ends of the brush. There is no difference in the force required when pushing and pulling, and it becomes constant.

The size of the vacuum on the bottom surface surrounded by the pair of wipers 210 and the water supply nozzles 230 at both ends is determined by the height of the protrusions formed on the wiper blade and the distance between the protrusions. The degree of adhesion of the brush to the surface is determined.

The magnitude of the force required when the worker performs the cleaning operation is reduced as the contact area with the floor is greatly reduced by the protrusion (C) on the dust surface (A), and the friction force is reduced on the mop surface (B). Friction is greatly reduced by the water (water film) formed between the blades, and the force required for cleaning is very small and light. In the process, the water film that reduces friction on the mop surface (B) blade disappears, and the friction force suddenly increases significantly, resulting in a lot of force. I am solving this problem.

In other words, the protrusions built by retracting inward from the tip of the mop surface (B) by a certain distance do not play any role as they do not touch the floor during the wet-mop cleaning process where water is supplied. However, when the water supply is cut off to finish cleaning, the water film disappears. As a result, the tip of the blade of the mop surface (B) increases the friction with the floor surface, causing the wiper blade to bend more and lie down. and the frictional force does not increase any more and maintains that state, so the force required to push and pull the operator stops increasing slightly and does not increase any more. By appropriately adjusting the retraction distance of the protrusion, which is erected by retracting from the end of the blade of the mop surface (B), the worker can finish cleaning without discomfort to the extent of feeling a slight difference in force.

On the other hand, when only dust cleaning is performed without wet mop cleaning, protrusions (C) and protrusions (D) are placed on both the dust side (A) and the mop side (B) as if cleaning with the water supply cut off in the final cleaning step described above. You can clean the dust without discomfort with a slight increase in friction by touching it, but if you still want lighter dust cleaning, it will be very light if you remove the front wiper without inserting it, but it is light enough that you don't have to do that.

The protrusion height of the blade of the wiper 210 provided on the lower housing 200 of the brush, the height of the rolling wheel 240, and the distance between the wiper and the rolling wheel depend on the brush performance (required power, cleaning condition, moisture remaining) It acts as a factor that has a great influence, and the proper combination of these is very important. In other words, the blade of the wiper should be higher than the height of the rolling wheel so that it can reach the floor first and perform the predetermined cleaning. Since the blade of the wiper is higher than the height of the rolling wheel, the wiper is compressed first and more force is required.

In the present invention, the correlation between the height of the rolling wheel 240 located behind the axis 310 line of the moving pipe 300 and the protruding height of the wiper blade ensures that the brush is stably seated on the floor and the wiper 210 is smoothly cleaned It must be designed to ensure operation.

The correlation between the height of the rolling wheel located behind the axis 310 line of the moving pipe 300 and the height of the rolling wheel located in front of the axis 310 line is related to the absorption of the force when the operator pushes forward to press the floor. It affects. Therefore, it should be designed to have an appropriate height correlation.

As we have seen above, we have looked at the factors that affect the amount of force required for the forward and backward movement of the brush and the factors that act on the removal of moisture from the floor. This determines the completeness of cleaning and the amount of force required for cleaning, so proper design of these various factors is necessary, and the resilience of the wiper material, which has a great influence on the removal of floor moisture, and the wear resistance of the material related to the lifespan of the wiper, , tensile strength, ozone resistance, etc., it would be important to select the wiper material, but the wiper material is not discussed here.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, but should be defined by not only the claims to be described later, but also those equivalent to these claims.
