The heating portions are continuously provided in the axial direction of the rotary cylinder 3. By the design, the cleaning part can be uniformly heated, and the cleaning performance is facilitated.

The heating device also comprises a heat insulation structure, and the heat insulation structure is used for transferring most of heat generated by the heating part to the cleaning part. The heat insulating structure is, for example, a heat insulating layer provided at the rear and around the heating member 5, so that the heat of the heating member 5 is mainly transferred to the front side, that is, mainly to the heat conductive member 4, and the heat conductive member 4 transfers the heat to the cleaning portion. The design is favorable for reducing waste and improving the heat utilization rate.

The side of the heating part facing the rotary cylinder 3 comprises an arc-shaped structure arranged around the rotary direction of the rotary cylinder 3, in this case, the heat conducting member 4 is arranged in an arc-shaped structure, i.e. the heat conducting member 4 is a concave arc-shaped plate. 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 embodiment, the liquid outlet member and the heating portion share a frame, the frame has a front panel, each liquid outlet hole 7 is provided on the front panel, each liquid outlet hole 7 is communicated with the liquid supply assembly, and the heating portion assembly is detachably connected with the frame.

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:

embodiment three phases compare embodiment one, and the difference lies in that heating portion and rotatory barrel 3 periphery are had and paste, clearance fit again, and the benefit of setting up like this is that provides very big flexibility, according to the characteristics of clean portion nimble setting paste, clearance fit to optimize the structure more.

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 uses a small volume that 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 design, the required amount of clean use can be better connected, the energy consumption is balanced, and the control program is more favorable for controlling the opening and closing heating element 5, because the larger the capacity of the transition water tank 6 is, in the dynamic use process, the more difficult the stability control of the working temperature is, when the capacity of the transition water tank 6 is smaller, the supply can be maintained to the supply amount, and then the balance point at the moment is more favorable for balancing the three elements of the energy consumption, the temperature stability control and the 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 passage of the transition water tank 6 is provided as a V-shaped labyrinth heating flow passage, and the entire outer shape of the transition water tank 6 is also substantially V-shaped in order to better match the rotary cylinder 3.

In this embodiment, as shown in fig. 7, the flow direction of the cleaning liquid in the V-shaped labyrinth heating flow channel is from the right upper end of the V-shaped labyrinth heating flow channel, and then flows out to the left upper end of the V-shaped labyrinth heating flow channel along the V-shape, so that after the design, on one hand, the flow distance is lengthened, so that the cleaning liquid has more time to absorb the heat generated by the heating element 5, and on the other hand, the cleaning liquid flows from bottom to top at the outlet side, so that the heat generated by the heating element 5 is better taken away by the cleaning liquid because the heat flows more easily upwards. 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 in the cleaning part without long-distance conveying, thereby greatly reducing waste, and in addition, the potential safety hazard caused by long-distance conveying is avoided, secondly, the utility model aims to know that the amount of the cleaning liquid in the transition water tank 6 is not 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, thereby the normal working state can be rapidly entered, the working response is very fast, 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 reaches 10 minutes, the heating element 5 is actively closed in advance, thereby the cleaning liquid heated finally is also used for cleaning the cleaned surface, the heated cleaning liquid can not be used up; of course, other measures can also be taken, such as for example switching off the heating element 5 beforehand, 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: first, 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 utilized more efficiently, because the front side of the heating member 5 directly heats the cleaning part, it is not necessary for the cleaning liquid in the transition water tank 6 to carry the heat to heat the cleaning part again, that is, one-time heat conversion is reduced, and the front side of the heating member 5 directly heats the cleaning part, which is advantageous in that it is advantageous to improve the structural compactness, 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 superimposed on the cleaning part preheated by the front side of the heating member 5, so that the heat generated by the heating member 5 can be utilized more efficiently, therefore, the heating time is very favorably shortened, 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 circumference 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 absorbs 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 design, thereby further reducing waste.

Example seven:
