Embodiment III:

compared with the first embodiment, the three-phase heating device is different in that the heating part is in contact with the periphery of the rotary cylinder body 3 and is in clearance fit, and the heating device has the advantages of providing great flexibility, flexibly setting the contact and the clearance fit according to the characteristics of the cleaning part, and optimizing the structure.

Embodiment four:

the fourth embodiment is different from the first, second and third embodiments in 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 clearance-fitted with the outer circumference of the rotary cylinder 3.

When the transition water tank 6 is added, the structure is as follows: the circumference of rotatory barrel 3 periphery is equipped with the heating portion, and heating portion and rotatory barrel 3 periphery clearance fit, and the heating portion includes transition water tank 6, and the heating element 5 of heating portion is arranged in transition water tank 6, and transition water tank 6 is used for being connected with the water source, and the heating element 5 is arranged in heating the cleaning liquid in the transition water tank 6, and the cleaning liquid flow direction cleaning portion after the heating, like this, the cleaning portion is also heated by the heat that cleaning liquid brought.

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. If it is necessary to further shorten the heating time, the heating element 5 may be provided in the flow path from the right side to the top.

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.
