The transition tank 6 adopts a small capacity which is smaller than the capacity of the water source.

Preferably, the small volume is within six times, including six times, the volume of the cleaning liquid supply flow per unit time. The supply amount of the cleaning liquid per unit time is set according to the cleaning requirement, and in general, it is advantageous to achieve or exceed the supply amount for better cleaning performance, but if the capacity of the transition water tank 6 is not limited, it is also important that the capacity of the transition water tank 6 is small, as in the present invention, "the transition water tank 6 employs a small capacity, which is smaller than the capacity of the water source. ". After the design, the required amount for cleaning and using can be better connected, the energy consumption is balanced, and the control program is more beneficial to controlling the opening and closing of the heating element 5, because the larger the capacity of the transition water tank 6 is, the more difficult the stability control on the working temperature is in the dynamic use process, the smaller the capacity of the transition water tank 6 is, and the supply amount can be maintained and supplied, so that the balance point at the moment is more beneficial to balancing the three elements of energy consumption, temperature stability control and 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 cleaning liquid flowing through in a short time.

In this example, as shown in fig. 7, the flow direction of the cleaning liquid in the V-shaped labyrinth heating flow channel is that the cleaning liquid flows in from the right upper end of the V-shaped labyrinth heating flow channel and then flows out from 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 flowing 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 on the outlet side, and because the heat flows more easily upwards, the cleaning liquid is enabled to better take away the heat generated by the heating element 5. In addition, because the flow channels on the left side and the right side are relatively close due to the V shape, when the heating element 5 heats, the cleaning liquid in the flow channel from the right side to the top is preheated, and when the cleaning liquid flows from the bottom to the top at the outlet side, the cleaning liquid can be heated to a higher temperature more quickly, and the heating time is shortened. In addition, the adoption of the V-shaped labyrinth heating flow passage makes the whole structure very compact.

Fifth embodiment:

As shown in fig. 2, 3, 4,5, 6 and 7, the arrows in fig. 7 indicate the flow direction of the cleaning liquid, and the fifth embodiment is different from the fourth embodiment in that not only the transition water tank 6 is added, but also the cleaning portion of the rotary cylinder 3 is heated by the heating portion, in which case, specifically, the heating member 5 is disposed around the circumference of the periphery of the rotary cylinder 3, the heating member 5 further includes a heat conducting member 4 while heating the cleaning liquid, and the heat conducting member 4 is disposed around the circumference of the periphery of the rotary cylinder 3, and the heating member 5 heats the cleaning portion of the rotary cylinder 3 by the heat conducting member 4 while heating the cleaning liquid.

The design has the technical effects that firstly, the heat generated in the front-back direction of the heating element 5 can be applied to the cleaning part more quickly, namely the front side of the heating element 5 is the cleaning part, the rear side of the heating element 5 is cleaning liquid, the heat generated in the front-back direction of the heating element 5 is more effectively utilized, because the front side of the heating element 5 directly heats the cleaning part, the cleaning liquid in the transition water tank 6 does not need to carry heat to heat the cleaning part, namely one heat conversion is reduced, and the front side of the heating element 5 directly heats the cleaning part has the advantages of improving the structural compactness, and the rear side of the heating element 5 can not directly heat the cleaning part, so that the cleaning part preheated by the front side of the heating element 5 is carried by the cleaning liquid in the transition water tank 6, the heat generated by the heating element 5 is more effectively utilized, the heating time is shortened, and the working temperature can be reached in a short term; secondly, the design of the V-shaped labyrinth heating flow passage is beneficial to further improving the structural compactness and further reducing the thickness dimension of the transition water tank 6, thirdly, when the V-shaped labyrinth heating flow passage is designed, the purpose of faster heating can be realized by arranging the heating element 5 in the flow passage from bottom to top at the left side of the V-shaped labyrinth heating flow passage, and the heating element 5 is not needed to be arranged in the flow passages at the left side and the right side of the V-shaped labyrinth heating flow passage, so that the whole structure is more optimized, meanwhile, the heat waste caused by arranging the heating element 5 in the flow passage at the left side and the right side of the V-shaped labyrinth heating flow passage is avoided, because if the heating element 5 is arranged in the flow passage from top to bottom at the right side of the V-shaped labyrinth heating flow passage, the heat transfer to the right side of the heating element 5 must be increased, and the cleaning liquid cannot absorb and take away the heat in time due to the speed of absorbing the heat, so that heat loss is caused, and the above scheme avoids the situation.

In this example, as shown in fig. 5 and 6, a second opening 10 is disposed on a side of the transition water tank 6 facing the rotary cylinder 3, and the second opening 10 is exposed by the heating element 5, so that the blocking between the transition water tank and the heat conducting element 4 is reduced, and the heat transfer of the heating element 5 through the heat conducting element 4 is facilitated. The design can make heating member 5 be close to clean portion more, also makes transition water tank 6 be close to clean portion more simultaneously to make the clean liquid after heating can be carried clean portion by the shorter distance, also make clean portion after heating meet with clean liquid after heating more fast, thereby furthest reduces the loss of heat, makes the less heating power of input, just can keep clean portion's temperature better, that is to say further improves the energy utilization, further promotes response performance simultaneously.

In this example, as shown in fig. 4, 5 and 6, in order to more uniformly output the heated cleaning liquid, a plurality of liquid outlet holes 7 are sequentially provided along the axial direction of the rotary cylinder 3, and the liquid outlet holes 7 communicate with the outlet ends of the V-shaped labyrinth heating flow passages via a plurality of communication holes 8, and therefore, the plurality of liquid outlet holes 7 are located on the upper side of the heat conductive member 4. The liquid inlet end 11 of the V-shaped labyrinth heating runner 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 switch 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.

In the case of simultaneous heating, other solutions are also possible, 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 part of the rotary cylinder 3 by the heated transition water tank 6 since the transition water tank 6 heats the cleaning liquid after heating.

Example six:

The sixth embodiment is different from the fifth embodiment in that the floor washing machine further comprises a dirt scraping plate 12, the dirt scraping plate 12 scrapes dirt on the cleaning part, namely, the dirt on the cleaning part is scraped off together with the dirt, and then the dirt is sucked away by a suction port 13 near the dirt scraping plate 12, which is also an operating characteristic of the floor washing machine. In the sixth embodiment, the transition water tank 6 is located at the rear side of the scraping plate 12 in the rotation circumferential direction of the rotation cylinder 3, that is, the cleaning portion scrapes the dirt first, and then the transition water tank 6 supplies heat including heat of the cleaning portion passing through the transition water tank 6 and heat brought by the heated cleaning liquid falling onto the cleaning portion from the liquid outlet hole 7, so that the heat can be utilized more effectively without wasting the heat at the contaminated portion (the portion of the contaminated cleaning portion) of the cleaning portion, because the heat is consumed after the cleaning portion cleans the surface to be cleaned, and if the dirty water is not removed in time, the portion of the cleaning portion where the dirty water is located (the portion of the contaminated cleaning portion) will reabsorb the heat, and the portion of the contaminated cleaning portion is unfavorable for cleaning, so that by the above-mentioned design, the heat is used more effectively, and the waste is further reduced.

Embodiment seven:

In this example, the main body 17 heats not only the cleaning liquid, but also the main body 17 is used to directly heat the cleaning portion because the main body 17 is itself thermally conductive, that is, the main body 17 is also used as the thermally conductive member 4, so that the temperature rise of the cleaning portion is more accelerated. By such design, not only is the response fast, but also the heat is mainly used for the cleaning portion because the heat heats the cleaning liquid by heating and directly heats the cleaning portion by the main body 17, and thus the energy utilization rate is high.
