It has the advantages of environmental protection, energy saving and high efficiency. When in use, the floor washing machine supplies water for cleaning through the water tank on it. In some cases, the cleaning effect of hot water is superior to that of normal temperature water. Therefore, most of them use a heating device to heat and raise the temperature of the water source in the water tank.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: Please refer to Figure 1 - Figure 2, the existing water tanks of floor washing machines are usually divided into a body water tank and a base station water tank. However, when heating the water source in the water tank, only the water source in one of the water tanks can be heated, which is not convenient for heating the water sources in different water tanks according to actual needs or heating the water sources in two water tanks simultaneously. Moreover, when the heated water source flows back, it can only enter the interior of one of the water tanks. To solve this technical problem, the following technical content is disclosed in this embodiment, including a water outlet pipe 1, one end of the water outlet pipe 1 is connected to the water tank, and the other end is connected to a pump body 2. The pump body 2 is connected to a water body heater 3 through a pipeline; it further includes: a solenoid valve 4 is provided at the water outlet end of the water body heater 3, and a water inlet pipe 5 and two return pipes are installed on the solenoid valve 4. One of the return pipes is connected to a water outlet plate, and the other return pipe is connected to the water inlet of the water tank. The water body heater 3 can adopt a heating sheet, a heating wire, an infrared heater, and a boiler, and the pump body 2 can adopt an electromagnetic pump, a peristaltic pump, and a water pump. The two return pipes are respectively a first return pipe 6 and a second return pipe 7, and the end of the first return pipe 6 away from the solenoid valve 4 is connected to the water outlet plate, and the end of the second return pipe 7 away from the solenoid valve 4 is connected to the water inlet of the water tank. The water outlet pipe 1 of the water tank can transport the water source in the body water tank or the base station water tank, as well as the water sources in the body water tank and the base station water tank, into the water body heater 3. The second return pipe 7 can return the hot water to the body water tank or the base station water tank, as well as the body water tank and the base station water tank.

[0027] When it is necessary to heat the water source in the water tank of the floor washing machine, the water source in the water tank is pumped into the water body heater 3 through the pump body 2 and the water outlet pipe 1 for heating. At this time, the water outlet pipe 1 can transport the water source in the base station water tank, the body water tank, or transport the water sources in the base station water tank and the body water tank simultaneously. After the water source is transported into the water body heater 3, it is heated and raised in temperature. Then, when the water inlet pipe 5 on the solenoid valve 4 is opened and the first return pipe 6 is closed, the heating method is to heat the water in the water tank, forming a water circulation mode. When the water inlet pipe 5 is closed and the first return pipe 6 is opened, the waterway can directly lead to the waterway plate for cleaning. At this time, the water temperature is relatively high, which can improve the cleaning efficiency and cleaning effect during cleaning or washing. When the first return pipe 6 controlled by the on-off of the solenoid valve 4 is closed and the second return pipe 7 is opened, the hot water can be connected to the water tank. The water tank connected by the second return pipe 7 can be the body water tank, the base station water tank, or both the base station water tank and the body water tank.

[0028] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. The following technical content is disclosed in this embodiment. A filter valve is provided at the water inlet end of the water body heater 3, and the filter valve can be disassembled at the water inlet end of the water body heater 3. A pressure relief valve is provided at the water body heater 3.

[0029] When heating the water source in the water tank, when the pump body 2 conveys the water source to the water heater 3 for heating, the water source entering the water heater 3 can be filtered by the filter valve, thereby removing impurities in the water source. At the same time, the filter valve can be disassembled to facilitate the subsequent cleaning of impurities in the pipeline. At the same time, a pressure relief valve is provided at the water heater 3, so as to prevent damage to electrical appliances and other components during long-term heating, and when the temperature is too high, the gas or liquid pressure is too high and is discharged.

[0030] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
