The floor washing machine is a cleaning machine which is suitable for cleaning hard floors, sucking sewage and separating the sewage from the cleaning floors. The household floor washing machine has the functions of sucking floor, mopping floor and self-cleaning, and can clean floors and carpets, thereby having wide application range. With the improvement of the technological level and the living standard, the application of the household floor washing machine is gradually increased. Under normal conditions, the floor washing machine is provided with components such as a clean water tank, a sewage tank, a rolling brush and the like, in the working process of the floor washing machine, clean water is sprayed onto the rolling brush or the ground, and dirt on the ground is sucked by the rolling brush component in the rotation process and is sucked into the sewage tank together with the sewage, so that the aim of cleaning the ground is fulfilled. At present, the single use time of the floor washing machine is generally 30-45 min, the clean water tank volume is 500-900 mL, and the sewage tank volume is 350-800 mL. The design of two independent water tanks makes the floor washing machine product body heavy and has a complex structure.

The embodiment of the disclosure discloses a communication type water tank and a floor washing machine. Through clear water tank and sewage case intercommunication, and the connecting portion sets up filtration module, makes sewage recycling back cyclic utilization, increases the single use duration of washing ground machine.

As shown in connection with fig. 1-4, embodiments of the present disclosure provide a communicating water tank for a floor scrubber. The connected tank includes a fresh water tank 100, a sewage tank 200, and a filter module. The clear water tank 100 is provided at the bottom with a first connection part 101. The second connection part 201 is provided at the top end of the sump 200, and the sump 200 is communicated with the fresh water tank 100. The filter module is disposed at the second connection portion 201. Wherein the fresh water tank 100 and the sewage tank 200 are detachably connected through the first connection part 101 and the second connection part 201, and the sewage tank 200 is disposed at the lower side of the fresh water tank 100.

The clean water tank 100 is provided with a clean water inlet 102, a first water outlet and a second water outlet. The sewage tank 200 is provided with a sewage inlet 203. Clean water is added into the clean water tank 100 from the clean water inlet 102, and is supplied to the rolling brush from the first water outlet or the second water outlet. When the rolling brush is wound around one circle, the sewage carries impurities into the sewage tank 200. The amount of water in the sump 200 increases and overflows to the filtering module. The upper overflow turbidity is reduced by the filtration of the filter module, and the cleaning cycle is participated again. The arrangement of the communicated water tank enables the sewage to be recycled, and the single-use time length of the floor washing machine is prolonged. Furthermore, the communicating water tank simplifies the structure of the water tank on the premise of ensuring the clean water quantity, so that the floor washing machine is lighter. Wherein the clean water can be replaced by cleaning water containing a cleaning agent.

Alternatively, the first connection part 101 is provided with an internal thread and the second connection part 201 is provided with an external thread. Wherein the first connection part 101 is screwed with the second connection part 201.

The first connection part 101 at the bottom of the fresh water tank 100 is provided with an internal thread, and the second connection part 201 at the top of the sewage tank 200 is provided with an external thread, as shown in fig. 2 and 3. The fresh water tank 100 is connected with the sewage tank 200 through threads, and the disassembly of the sewage tank 200 is facilitated on the basis of expanding the water tank. The sewage tank 200 can be disassembled to clean the impurities accumulated therein.

Alternatively, the second connection 201 has a width H and the fresh water tank 100 has a width H. Wherein H is more than or equal to 1/3 and H is more than or equal to 2/3.

The width of the second connection part 201, i.e., the range defined by the second connection part 201, can be understood as the range where the fresh water tank 100 communicates with the sewage tank 200. The width of the second connection part 201 is set to be 1/3 H.ltoreq.h.ltoreq.2/3H with respect to the width of the fresh water tank 100. The communication part is too small, the overflow filtering efficiency of the water in the sewage tank 200 is low, and the pressure of the communication part is increased, so that the smoothness of the water outlet of the communication type water tank is further influenced. The communication part is too large, the water overflow rate in the sewage tank 200 is too high, the clean water and the overflow water are easy to mix, and the single use time is reduced.

Optionally, the second connecting portion 201 encloses a filtering space 202, and the filtering module is disposed in the filtering space 202.

The second connection portion 201 is provided with external threads corresponding to the internal threads of the first connection portion 101. The second connection portion 201 is formed to be a communication range between the fresh water tank 100 and the sewage tank 200. The filter module is arranged in the space enclosed by the second connecting part 201, so that the overflowed water of the sewage tank 200 can be filtered by the filter module, and the sewage can enter the circulation after the turbidity is reduced.

Optionally, the filtration module comprises a first filter 301 and a second filter 302. The first filter 301 is disposed in the filtering space 202, two ends of the first filter 301 are connected to the second connecting portion 201, and the first filter 301 is used for filtering sewage. The second filter 302 is disposed below the first filter 301, two ends of the second filter 302 are connected to the second connection portion 201, and the second filter 302 is used for filtering sewage.

The filtering module comprises a first filtering piece 301 and a second filtering piece 302, and double-layer filtering enables overflow water on the sewage tank 200 to be filtered for multiple times, so that the turbidity is greatly reduced, and recycling of overflow water can be realized. The first filter 301 is connected to the second connection portion 201 at both ends, and the second filter 302 is connected to the second connection portion 201 at both ends, which can be understood that the filter module entirely covers the communication end surface. The first filter 301 and the second filter 302 cover the communicating end surfaces, so that the overflow water flowing through the sewage tank 200 of the filter module is filtered twice, and the filtering effect of the overflow water of the sewage tank 200 is improved.

Optionally, the first filter 301 comprises a filter membrane.

Optionally, the second filter 302 comprises a filter mesh.

The first filter 301 and the second filter 302 are disposed one above the other, and the first filter 301 and the second filter 302 are the same size. The first filter 301 is adjacent to the clean water tank 100 and the second filter 302 is adjacent to the dirty water tank 200. The water in the sump 200 overflows, first, through the second filter member 302, so the second filter member 302 may be provided as a filter screen, and the overflow is primarily filtered. The primary filtration is coarse filtration, and the filter screen is 20-50 meshes. For example, the second filter 302 may be a 20 mesh, 25 mesh, 30 mesh, 35 mesh, 40 mesh, 45 mesh, or 50 mesh filter screen. The overflow water passes through the second filter 302 and then flows through the first filter 301, and the first filter 301 is fine-filtered, so that the first filter 301 is set as a filtering membrane. The filtering membrane is 50-100 meshes. For example, the first filter 301 may be a 50 mesh, 60 mesh, 70 mesh, 80 mesh, 100 mesh or the like filter membrane. The mesh, i.e., the number of holes, is the number of holes per square inch. The larger the mesh number, the smaller the pore size. In general, mesh×pore size (micrometers) =15000. For example, 400 mesh pore size is 38 microns; the 500 mesh pore size was 30 microns. It is understood that the larger the mesh number, the smaller the particle size of the passing material, i.e. the better the overflow filtering effect. Wherein the second filter member 302 may also be provided as a filter membrane. The first filter 301 and the second filter 302 may be made of stainless steel, ceramic, polymer, fabric, etc., and are fixed to the second connection portion 201 by an insert.

Wherein, sealing rings can be arranged at the connection parts of the first filter element 301 and the second filter element 302 and the second connection part 201. The sealing ring enables the first filter element 301 and the second filter element 302 to be in seamless connection with the second connecting portion 201, and further improves the filtering effect of the filtering module. The sealing ring is made of rubber, thermoplastic elastomer or the like.

Optionally, clean water tank 100 is provided with clean water inlet 102 and sewage tank 200 is provided with sewage inlet 203.

Clean water tank 100 is provided with a clean water inlet 102 for adding clean water or clean water to the connected tank. To facilitate the addition of water, a fresh water inlet 102 is typically provided at the top of the fresh water tank 100. The sewage tank 200 is provided with a sewage inlet 203 for recovering sewage on the roll brush. Accordingly, the sewage inlet 203 is provided at the bottom end of the sewage tank 200, close to the rolling brush.

Optionally, the connected tank further comprises a seal 400. The sealing member 400 is disposed on the clean water tank 100, and the sealing member 400 is used for covering the clean water inlet 102.

The sealing member 400 is disposed on the top of the clean water tank 100 and is used to cover the clean water inlet 102, so as to prevent water in the clean water tank 100 from overflowing into other areas of the floor scrubber during use. The seal 400 comprises a sealing plug, and is made of rubber, thermoplastic elastomer or the like.

Alternatively, the volume of the fresh water tank 100 is greater than the volume of the sewage tank 200.

The embodiment of the present disclosure communicates the clean water tank 100 with the sewage tank 200, and enables recycling of the recovered sewage through a filtering module at the communication place. The volume of the fresh water tank 100 is set to be larger than the volume of the sewage tank 200. The single use time can be further increased. If the capacity of the sewage tank 200 is set to be larger than that of the clean water tank 100, after the turbidity of the overflow water is increased, the clean water is very easy to be uniformly mixed with the overflow water, so that the whole turbidity of the clean water tank 100 is increased, and the service time is shortened.

The embodiment of the disclosure also provides a floor washer, which comprises the communication type water tank.

The communicating water tank provided by the embodiment of the disclosure further comprises a spray head. The sewage tank 200 is provided with a sewage inlet 203, and a spray head is provided at the sewage inlet 203. The spray head is used to spray the sewage of the scrubber into the sewage tank 200 toward the inner wall of the sewage tank 200. Wherein the inner wall of the sewage tank 200 is provided with a protrusion 204 for intercepting impurities in the sewage tank 200.

The sewage tank 200 is provided with a sewage inlet 203, and the nozzle is provided at the sewage inlet 203. When the floor scrubber recovers sewage, the sewage is diffusely sprayed into the sewage tank 200 by the spray heads, and the multi-angle water outlet increases the turbulence of water in the sewage tank 200, so that the water in the sewage tank 200 flows irregularly. Impurities in the sewage move along the water flow direction. The inner wall of the sewage tank 200 is provided with a bulge 204, when impurities move to the bulge 204 and are accumulated on the lower side of the bulge 204, the impurities are far away from the filter screen or the filter membrane, and then the floor scrubber can normally run out of water.

Optionally, the spray head comprises a screw spray head 500. The jet angle of the spiral jet 500 is greater than or equal to 50 degrees and less than or equal to 170 degrees.

The spiral spray nozzle 500, also called a desulfurization spray nozzle, an anti-blocking spray nozzle, a high-flow spray nozzle, a dust removal spray nozzle and a corrosion resistant spray nozzle, is a solid conical or hollow conical spray nozzle, and the spray angle can be 50-170 degrees. For example, a screw head 500 of 50 °, 70 °, 90 °, 120 °, 150 °, 170 °, or the like may be used. The liquid flow rate ranges from 5.5 to 4140 liters/min. The compact spray head has a smooth flow passage, so that the blockage of liquid can be reduced to the greatest extent, and the liquid can reach the maximum flow rate on a pipeline with a given size. The recovered sewage is changed into tiny liquid beads to spray out to form mist after being tangent to and collided with the continuously-reduced spiral surface. The streamline design from the inlet to the outlet in the nozzle cavity reduces the resistance coefficient to the minimum, and the sewage recovery is smoother. The large-angle jet angle can increase turbulence of water in the sewage tank 200 at multiple angles, so that water in the sewage tank 200 flows irregularly, for example, flows around. The spiral spray head 500 sprays at a large angle to the periphery to prevent the sewage carrying impurities from directly flowing to the filter module to cause blockage.

Optionally, the protrusion 204 comprises a threaded protrusion. The screw protrusions are circumferentially provided to the inner wall of the sump 200.

The water in the sewage tank 200 flows around by the recycled sewage sprayed from the nozzles, and the impurities also flow along with the water. As the impurities flow down to the protrusions 204, they are deposited on the underside of the protrusions 204. The screw protrusions are circumferentially provided on the inner wall of the sump 200, increasing the stacking sites of the impurities, so that more impurities are stacked under the protrusions 204 of the inner wall.

Optionally, the threaded protrusion comprises a plurality of convolutions including a bottom convolutions proximate the bottom surface of the tank 200. Wherein, the vertical distance between the bottom spiral coil and the bottom surface of the sewage tank 200 is a first distance, and the first distance is greater than or equal to a preset distance.

The provision of a plurality of coils similarly increases the sites for depositing impurities, causing more impurities to be deposited under the protrusions 204 of the inner wall.

Alternatively, the vertical distance between the top water spraying position of the spiral spray head 500 and the bottom surface of the sewage tank 200 is the second distance. Wherein the first distance is greater than or equal to the second distance.

The vertical distance between the bottom spiral coil and the bottom surface of the sewage tank 200 is a first distance, and the vertical distance between the top water spraying position of the spiral spray head 500 and the bottom surface of the sewage tank 200 is a second distance. The first distance is greater than or equal to the second distance. It will be appreciated that the top water spray height of the spiral spray head 500 is lower than the bottom coil height. The arrangement is such that the outlet water of the spray head interferes with the water in the sewage tank 200 from the bottom of the sewage tank 200, thereby driving the water at the upper part to flow.

Alternatively, the spiral spray head 500 is provided at a bottom center position of the sump 200.

Similarly, the spiral spray head 500 is arranged at the bottom center of the sewage tank 200, and the spray head discharges water in a large range and symmetrically, so that the water in the sewage tank 200 is better driven to flow.

Optionally, the connected tank further comprises an ultrasound module 600. The ultrasonic module 600 is provided to the sewage tank 200, and the ultrasonic module 600 serves to peel off impurities attached to the protrusions 204.

After the floor scrubber is used or impurities accumulated on the inner wall of the sewage tank 200 are increased, the sewage tank 200 needs to be cleaned. The floor scrubber is stopped, the ultrasonic module 600 is started, and the foreign substances attached to and accumulated on the lower side of the protrusions 204 are peeled off by ultrasonic vibration. The tank 200 is then removed by screwing the threads of the first and second connection parts 101 and 201, and the tank 200 is cleaned.

Optionally, the connected water tank further comprises a filtration module. The filtering module is disposed at the junction of the clean water tank 100 and the sewage tank 200. The filtering module is disposed at the junction of the clean water tank 100 and the sewage tank 200, and is used for filtering the overflow water in the sewage tank 200, so that the turbidity of the overflow water is reduced and the overflow water participates in the cleaning cycle again.

Alternatively, the fresh water tank 100 is detachably connected with the sewage tank 200. The detachable connection of the fresh water tank 100 to the sewage tank 200 facilitates the cleaning of impurities in the sewage tank 200.

The embodiment of the disclosure provides a floor washer, which comprises the communicated water tank. Wherein the sewage tank 200 of the connected tank is as described above.

The communicating water tank provided in the embodiment of the present disclosure further includes a first water outlet pipe 103, a second water outlet pipe 104, a total water outlet pipe 105, and a peristaltic pump 700. The side wall of the clear water tank 100 is provided with a first water outlet and a second water outlet. The first end of the first water outlet pipe 103 is communicated with the first water outlet. The first end of the second water outlet pipe 104 is communicated with the second water outlet, and the second end of the second water outlet pipe is intersected with the second end of the first water outlet pipe 103. The first end of the total water outlet pipe 105 is communicated with the junction of the first water outlet pipe 103 and the second water outlet pipe 104. Peristaltic pump 700 is disposed at a first end of the main outlet pipe 105. The sump 200 communicates with the fresh water tank 100. The filtering module is disposed at the junction of the clean water tank 100 and the sewage tank 200. Wherein, the second water outlet is arranged below the first water outlet, and the peristaltic pump 700 is used for communicating the first water outlet pipe 103 with the total water outlet pipe 105, or the peristaltic pump 700 is used for communicating the second water outlet pipe 104 with the total water outlet pipe 105.

Clean water tank 100 of the connected tank supplies clean water and sewage tank 200 recovers sewage. And water in the sewage tank 200 overflows after sewage is recovered, and the filtered water is filtered by the filtering module to form circulating water into the clean water tank 100. The clear water tank 100 is provided with a first water outlet and a second water outlet up and down, and the second water outlet is opened first, and circulating water is used for the rolling brush. And when the dirt degree at the second water outlet is increased, closing the second water outlet and opening the first water outlet. Peristaltic pump 700 may communicate with first outlet tube 103 and total outlet tube 105, or with second outlet tube 104 and total outlet tube 105. The arrangement can enable the floor washing machine to be effectively cleaned after a period of operation, and further, the single-use time length of the floor washing machine is prolonged.

Optionally, the floor scrubber further comprises a third filter 303. The third filter 303 is disposed between the first water outlet and the second water outlet.

A third filter 303 is provided in the fresh water tank 100 and is located between the first water outlet and the second water outlet. In one aspect, the third filter 303 further filters the overflow water of the sump 200. On the other hand, the third filter 303 reduces the mixing rate of the fresh water or the clean water in the fresh water tank 100 with the overflow water of the sewage tank 200.

Optionally, the floor scrubber further comprises an over-current sterilization module 800. The overflow sterilization module 800 is disposed on the total water outlet pipe 105, and is used for sterilizing water flowing through the total water outlet pipe 105.

The overflow sterilization module 800 is disposed on the main water outlet pipe 105 and near one side of the rolling brush. The water from the first water outlet or the second water outlet is guided to the main water outlet pipe through the peristaltic pump 700. After flowing through the total water outlet pipe 105, the sterilized water is sterilized by the flow sterilizing module 800, and the sterilized water is used for a rolling brush. The overcurrent sterilization module 800 includes an overcurrent ultraviolet sterilizer and the like. The overcurrent type sterilizing equipment is not contacted with a water source, and the ultraviolet lamp is used for irradiating and sterilizing at the moment of water flow passing.

s01, the floor washing machine obtains a turbidity value at a second water outlet of the communication type water tank;

s02, selectively opening a first water outlet or a second water outlet of the communication type water tank according to the turbidity value by the floor washing machine. The floor washing machine is the floor washing machine comprising the communicated water tank.

Optionally, the floor washing machine selectively opens the first water outlet or the second water outlet of the communication type water tank according to the turbidity value, and the floor washing machine comprises: when the turbidity value is smaller than a first preset turbidity value, the floor washing machine controls the second water outlet to be opened, and the first water outlet is closed; when the turbidity value is greater than or equal to a first preset turbidity value, the floor washing machine controls the first water outlet to be opened, and the second water outlet is closed.

When the turbidity value is smaller than the first preset turbidity value, namely the overflow water is in a clear state, the circulation is started first. When the turbidity value is greater than or equal to the first preset turbidity value, i.e., the overflow turbidity is greater, the cleaner water in the upper portion of the clean water tank 100 is activated for cleaning.

Optionally, when the turbidity value is greater than or equal to a first preset turbidity value, the floor scrubber controls the first water outlet to be opened, and the second water outlet to be closed, and the floor scrubber further comprises: when the increasing speed of the turbidity value is larger than or equal to the first preset speed, the floor washing machine reduces the rotating speed of the rolling brush of the floor washing machine.

When the increasing rate of the turbidity value is greater than or equal to the first preset rate, that is, the overflow turbidity of the sewage tank 200 is increased, the mixing rate of the water in the clean water tank 100 caused by the vibration of the body of the scrubber due to the rotation of the drum brush is reduced by decreasing the rotation speed of the drum brush of the scrubber. Specifically, when the increasing rate of the turbidity value is smaller than the first preset rate, the floor washing machine can be set to adjust the rolling brush of the floor washing machine to be switched to the first preset rotating speed. When the increasing speed of the turbidity value is larger than or equal to the first preset speed, the floor washer adjusts the rolling brush of the floor washer to be switched into the second preset rotating speed. The first gear preset rotating speed is more than or equal to 300r/min and less than or equal to 400r/min. The second gear preset rotating speed is more than or equal to 400r/min and less than or equal to 550r/min. The rotating speed is too small, so that the cleaning efficiency of the floor washer is reduced; the power consumption rate of the rolling brush motor of the floor washing machine is increased due to the overlarge rotating speed, so that the single-use time of the floor washing machine is shortened.

Optionally, the control method further includes: when the increasing rate of the turbidity value is greater than or equal to the second preset rate, the rotation rate of the spiral spray head 500 at the water inlet of the sump 200 is reduced. Wherein the second preset rate is greater than the first preset rate.

Also, when the increasing rate of the turbidity value is greater than or equal to the second preset rate, it can be understood that the overflow turbidity of the sewage tank 200 is further increased. The second preset rate is greater than the first preset rate. At this time, the rotation rate of the spiral nozzle 500 at the water inlet of the sump 200 is reduced, so that the flowing impulse of the water in the sump 200 is reduced, and the accumulation of the impurities to the filter module is promoted when the water in the sump 200 flows too fast in four directions and the impurities are too much.

The floor scrubber also includes a level sensor 902 disposed at the bottom of the tank 200. The level sensor 902 feeds back the level value in the connected tank through the hydraulic pressure parameter. After the floor washing machine is started, when the liquid level value is greater than or equal to the height of the first water outlet, the floor washing machine is started normally and the first water outlet or the second water outlet is selected to discharge water. When the liquid level value is smaller than the height of the first water outlet, the floor washing machine prompts to continuously add water until the liquid level reaches the height of the first water outlet, and then the floor washing machine is started normally.

As shown in conjunction with fig. 6, the embodiment of the present disclosure further provides a control device 1001 for a floor scrubber, including a turbidity acquisition module 1002 and a water outlet selection module 1003. The turbidity acquisition module 1002 is configured to acquire a turbidity value at a second water outlet of a connected tank of the floor scrubber. The outlet selection module 1003 is configured to selectively open the first outlet or the second outlet of the communication-type water tank according to the turbidity value. The floor washing machine is the floor washing machine comprising the communication water tank.

Wherein, turbidity acquisition module 1002 includes turbidity sensor 901 disposed in fresh water tank 100.
