After designing like this, concave arc matches with clean portion outer peripheral face, is favorable to clean portion smooth and easy rotation on the one hand, and on the other hand is favorable to concave arc and the good laminating of clean portion to promote heat transfer efficiency.

In this example, the transitional water tank 6 is not provided, the above structure can be shown in fig. 1, 2, 4 and 5, and other structures in fig. 2, 4 and 5 can be configured without the transitional water tank 6.

In this case, a liquid outlet member can be used as the heat conducting member 4, so that liquid outlet and heating can be simultaneously realized.

Example two:

the second embodiment is different from the first embodiment in that the heating portion is in clearance fit with the outer periphery of the rotary cylinder 3, so that the technical effects of reducing the rotation resistance of the rotary cylinder 3, reducing the abrasion, reducing the extrusion on the cleaning portion, and avoiding the loss of the cleaning liquid caused by the extrusion of the cleaning liquid in the cleaning portion are achieved.

Example three:

the difference between the first embodiment and the third embodiment is that the heating part is attached to the periphery of the rotary cylinder 3 and is in clearance fit with the periphery of the rotary cylinder, and the advantages of the arrangement are that great flexibility is provided, and the attachment and the clearance fit are flexibly arranged according to the characteristics of the cleaning part, so that the structure is optimized.

Example four:

fourth embodiment the difference from the first, second and third embodiments is that a transition water tank 6 is added, and a heating part is used for heating the cleaning liquid supplied to the cleaning part, and the heating part is preferably in clearance fit with the outer circumference of the rotary cylinder 3.

After adding transition water tank 6, the structure is: the circumference of 3 peripheries of rotatory barrel is equipped with heating portion, heating portion and 3 periphery clearance fits of rotatory barrel, and heating portion includes transition water tank 6, and the heating member 5 of heating portion is arranged in transition water tank 6, and transition water tank 6 is arranged in being connected with the water source, and heating member 5 is arranged in heating the cleaning fluid in the transition water tank 6, and the cleaning fluid flow after the heating is to cleaning portion, and like this, cleaning portion is also heated by the heat that cleaning fluid took.

The transition tank 6 is of a small volume, which is less than the volume of the water source.

Preferably, the small volume is within six times, including six times, the volume of the cleaning liquid supply flow rate per unit time. The supply of cleaning liquid per unit time is set according to the cleaning needs, and generally, reaching or exceeding this supply is favorable for better cleaning performance, but if the capacity of the transition water tank 6 is not limited, it will cause drawbacks, so the capacity of the transition water tank 6 is also important, just like the utility model discloses a "the transition water tank 6 adopts the small capacity, and this small capacity's capacity is less than the capacity of water source. ". According to the aforesaid design after, can link up the required volume of clean use so better, balanced energy consumption simultaneously, also more be favorable to controlling program control switching heating member 5 in addition, this is because the transition water tank 6 capacity is bigger, in the dynamic use in-process, to operating temperature's stability control more difficult, when transition water tank 6 capacity is less, can maintain the supply to the supply volume again simultaneously, the balance point then this moment, then more be favorable to balanced energy consumption, temperature stability control, three key elements of cleaning performance.

A labyrinth heating flow passage is arranged in the transition water tank 6 and is used for enabling the heating element 5 to rapidly heat the flowing cleaning liquid in a short time. In this example, as shown in fig. 7, the labyrinth heating flow path of the transition water tank 6 is provided as a V-shaped labyrinth heating flow path, and the entire outer shape of the transition water tank 6 is also substantially V-shaped in order to match the rotary cylinder 3 more favorably.

In this example, as shown in fig. 7, the cleaning liquid in the V-shaped labyrinth heating flow channel flows in from the upper right end of the V-shaped labyrinth heating flow channel and then flows out to the upper left end of the V-shaped labyrinth heating flow channel along the V-shape, so that the flow distance is lengthened to allow the cleaning liquid to absorb more time the heat generated by the heating element 5, and the cleaning liquid flows from bottom to top on the outlet side to allow the cleaning liquid to better take away the heat generated by the heating element 5 because the heat flows more easily upward. In addition, because the V-shaped flow channels on the left side and the right side are relatively close, when the heating element 5 generates heat, the cleaning liquid in the flow channel from top to bottom on the right side is preheated, and when the cleaning liquid flows from bottom to top on the outlet side, the cleaning liquid can be heated to a higher temperature more quickly, so that the heating time is shortened. In addition, the V-shaped labyrinth heating flow channel is adopted, so that the whole structure is very compact. If the heating time needs to be further shortened, the heating elements 5 can be arranged in the right-side flow passage from top to bottom at the same time.

After the design, the following technical effects are achieved: firstly, the cleaning liquid in the transition water tank 6 is heated and then used for a cleaning part without long-distance conveying, so that the waste is greatly reduced, in addition, the potential safety hazard caused by long-distance conveying is also avoided, secondly, the utility model aims to know that the amount of the cleaning liquid in the transition water tank 6 cannot be set much, so that the heat generated by the heating element 5 is enough to heat the cleaning liquid in the transition water tank 6 in a short time, so that the normal working state can be quickly entered, the working response is very quick, and thirdly, when the work is stopped, the cleaning liquid remained in the transition water tank 6 is not much, so that the waste heat is little, in addition, when the work is stopped, the work can be closed in advance, for example, the work time is set to be 10 minutes, when the work stop time is reached for 10 minutes, the heating element 5 is actively closed in advance, so that the cleaning liquid heated finally is also used for cleaning the surface, and the heated cleaning liquid cannot be used up; of course, other measures can also be taken, such as for example switching off the heating element 5 in advance, but letting the rotary drum 3 continue to rotate, while the hot cleaning liquid remaining in the intermediate water tank 6 continues to be supplied, so that the rotary drum 3 can thereby clean itself, thus utilizing the heat of this part of the cleaning liquid remaining in the intermediate water tank 6, and thus taking this measure also further reduces waste.

Example five:

as shown in fig. 2, 3, 4, 5, 6, and 7, an arrow in fig. 7 indicates a flow direction of the cleaning liquid, and a fifth embodiment is different from the fourth embodiment in that not only the transition water tank 6 is added, but also the cleaning part of the rotary cylinder 3 is heated by the heating part, specifically, in this embodiment, the heating member 5 is disposed around the circumference of the outer circumference of the rotary cylinder 3, the heating member 5 heats the cleaning liquid and also includes the heat conductive member 4, the heat conductive member 4 is disposed around the circumference of the outer circumference of the rotary cylinder 3, and the heating member 5 heats the cleaning part of the rotary cylinder 3 through the heat conductive member 4 while heating the cleaning liquid.

The technical effect that design has like this is: firstly, the heat generated in the front-back direction of the heating member 5 can be applied to the cleaning part more quickly, that is, the front side of the heating member 5 is the cleaning part, and the back side of the heating member 5 is the cleaning liquid, so the heat generated in the front-back direction of the heating member 5 can be more efficiently utilized, because the front side of the heating member 5 directly heats the cleaning part, the cleaning part is not required to be heated by the heat carried by the cleaning liquid in the transition water tank 6, that is, one-time heat conversion is reduced, and the front side of the heating member 5 directly heats the cleaning part, the advantage of being beneficial to improving the structure compactness is also achieved, and the back side of the heating member 5 can not directly heat the cleaning part, so the heat carried by the cleaning liquid in the transition water tank 6 is superposed on the cleaning part preheated by the front side of the heating member 5, so the heat generated by the heating member 5 is more efficiently utilized, the advantage of being very beneficial to shortening the heating time, and the working temperature can be reached in a short time; secondly, the purpose that heat is utilized more efficiently is achieved, and meanwhile, the structure compactness is further improved, so that the thickness size of the transition water tank 6 is further reduced; thirdly, when designing the V-maze heating channel, the purpose of heating faster can be realized only by arranging the heating member 5 in the channel from bottom to top on the left side of the V-maze heating channel, and it is not necessary to arrange the heating member 5 in the channels on the left and right sides of the V-maze heating channel, so that the overall structure is more optimized, and at the same time, the heat waste caused by arranging the heating member 5 in the channels on the left and right sides of the V-maze heating channel is avoided, because if the heating member 5 is arranged in the channel from top to bottom on the right side of the V-maze heating channel, the heat transfer of the heating member 5 to the right side is inevitably increased, and because the speed of absorbing heat by the cleaning liquid is controlled, the heat can not be absorbed and taken away in time, thereby causing heat loss, and the above scheme avoids the situation.

In this embodiment, as shown in fig. 5 and 6, a second opening 10 is provided at a side of the transition water tank 6 facing the rotary cylinder 3, and the second opening 10 is used for exposing the heating element 5, so as to reduce the obstruction with the heat conducting element 4, and further facilitate the heat transfer of the heating element 5 through the heat conducting element 4. Design like this can make heating member 5 be close to the cleaning part more, also make transition water tank 6 be close to the cleaning part more simultaneously, thereby make the cleaning liquid after the heating can be carried the cleaning part by shorter distance, also make the cleaning part after the heating meet with the cleaning liquid after the heating more fast, thereby reduce thermal loss to the utmost, make the less heating power of input, just can maintain the temperature of cleaning part better, that is to say further improve energy utilization, further promote response performance simultaneously.

In this example, as shown in fig. 4, 5, and 6, in order to more uniformly discharge the heated cleaning liquid, a plurality of liquid outlet holes 7 are provided in order along the axial direction of the rotary cylinder 3, and the liquid outlet holes 7 are communicated with the outlet end of the V-labyrinth heating flow path through a plurality of communication holes 8, and therefore, the plurality of liquid outlet holes 7 are located above the heat conductor 4. The liquid inlet end 11 of the V-shaped labyrinth heating flow channel is communicated with a water source, namely a cleaning liquid tank, through a pipeline. A water pump may be provided to increase the delivery pressure of the cleaning liquid. It is also possible to turn off the heating member 5 in time by detecting the water level of the cleaning liquid tank and/or whether the cleaning liquid is present in the pipe, thereby achieving higher safety performance, such as dry burning prevention performance.

Other solutions are also possible for the case of simultaneous heating, for example, the heating element 5 heats the cleaning part of the rotary cylinder 3 directly by the heating element 5 while heating the cleaning liquid, and for example, the heating element 5 heats the cleaning liquid while heating the transition water tank 6, so that the cleaning part of the rotary cylinder 3 can be heated by the heated transition water tank 6.

Example six:

the sixth embodiment is different from the fifth embodiment in that it further comprises a dirt scraping plate 12, and the dirt scraping plate 12 scrapes off the dirt on the cleaning portion together with the dirt, and then the dirt is sucked by the suction port 13 near the dirt scraping plate 12, which is also the working characteristic of the floor washing machine. In the sixth embodiment, the transitional water tank 6 is located at the rear side of the dirt scraping plate 12 along the rotation circumferential direction of the rotary cylinder 3, that is, the cleaning part scrapes dirt first, and then the transitional water tank 6 supplies heat, which includes heat for heating the cleaning part passing through the transitional water tank 6 and heat brought by heated cleaning liquid falling from the liquid outlet hole 7 onto the cleaning part, so that the heat can be used more effectively, and the heat is not wasted in the polluted part (the polluted part of the cleaning part) of the cleaning part, because the heat is consumed after the cleaning part cleans the surface to be cleaned, and then if the sewage is not removed in time, the part (the polluted part) of the cleaning part where the sewage is located will absorb heat again, and the polluted part of the cleaning part is not beneficial to cleaning, so that the heat is used more effectively by the above design, thereby further reducing the waste.

Example seven:

compared with the above embodiments, the seventh embodiment is different in that a plurality of heating portions are provided, each heating portion is provided along the axial direction of the rotary cylinder 3, the axial length of each heating portion is substantially equal to that of the cleaning portion, and each heating portion is further provided sequentially along the circumferential direction of the rotary cylinder 3, that is, compared with the structure of one heating portion shown in fig. 2, at least one heating portion is further added sequentially along the circumferential direction of the rotary cylinder 3 to form a structure of two heating portions.

Example eight:

eighth embodiment differs from the above-described embodiments in that a temperature sensor is further included, the temperature sensor being configured to detect a temperature of the heating portion and/or a temperature of the cleaning liquid supplied to the cleaning portion and/or a temperature of the surface to be cleaned.

Through setting up temperature sensor, the technical effect that can obtain is: on the one hand, a structural basis is provided for more intelligently controlling heating, and the control program is combined to help further fine control of energy consumption, on the other hand, the safety can be further improved, and one guarantee is added for safety.

Example nine:

as shown in fig. 11 to 17, the transitional water tank 6 is eliminated in this example, there is no concept of a water tank, the liquid outlet member is used as a heating portion at the same time, the cleaning liquid directly flows through the liquid outlet member, the liquid outlet member heats the cleaning liquid, the whole volume of the heating portion is greatly reduced, and liquid is fed from one end, and liquid is not required to be fed from the liquid inlet end 11 at the upper middle position as shown in fig. 3, the above measures are beneficial to reducing the volume of the rolling brush, or more space is reserved for installing other structures, for example, as shown in fig. 9, as more installation space is reserved, the water pump 26 can be integrated into the rolling brush, and in this example, the water pump 26 is located at the side where the liquid inlet joint 16 is located.

In this embodiment, the liquid outlet member not only heats the cleaning liquid, but also conducts heat, so that the liquid outlet member can be used to directly heat the cleaning portion, i.e. the liquid outlet member is also used as the heat conduction member 4, for example, the main body 17 is used as the heat conduction member 4, thereby increasing the temperature of the cleaning portion. By the design, the response is fast, and the heat is mainly used for the cleaning part because the heat directly heats the cleaning part by heating the cleaning liquid and discharging the liquid, so that the energy utilization rate is high.

Example ten:

compared with the ninth embodiment, a concave part 22 extending along the axial direction of the rotary cylinder 3 is arranged on one side of the body of the liquid outlet piece, which is positioned on the rotary cylinder 3, and a liquid outlet hole 7 is arranged in the concave part 22.
