[0026] It should be noted that the terms "one", "multiple" in the present disclosure are illustrative and not restrictive, and those skilled in the art should understand that, unless otherwise explicitly stated in the context, it should be understood as "one or more".

[0027] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0028] As Figure 1As shown in Fig. 4, a hot water washing machine comprises a machine body 1, a water tank 2, a heating tank 3, a water pump 4, a battery pack 5, a rolling brush 6, a water outlet plate 7, a main air blower 8 and an air supply pipe 9. The water tank 2 is arranged in the machine body 1 and used for storing cleaning liquid. The heating tank 3 has a heating function, is arranged in the machine body 1 and electrically connected with the battery pack 5, and is used for heating the cleaning liquid. The water pump 4 is arranged in the machine body 1, electrically connected with the battery pack 5, and used for conveying the cleaning liquid in the water tank 2 to the heating tank 3. The battery pack 5 is arranged in the machine body 1 and used for supplying power to other components. The rolling brush 6 is arranged at the bottom of the machine body 1 and used for cleaning the ground. The machine body 1 is provided with a motor for driving the rolling brush 6 to rotate. The water outlet plate 7 is arranged in the machine body 1 and located above the rolling brush 6, and is used for spraying the cleaning liquid in the heating tank 3 on the rolling brush 6. The main air blower 8 is arranged in the machine body 1. One end of the air supply pipe 9 is connected with the main air blower 8, and the other end is aligned with the rolling brush 6. In normal use, when stubborn stains or low-temperature environment are encountered, the hot water washing mode is started. The cleaning liquid in the water tank 2 is pumped to the heating tank 3 by the water pump 4, and is heated to generate hot water with a temperature of 80 degrees or above in the heating tank 3. The hot water flows into the water outlet plate 7 through the pipeline, and flows to the rolling brush 6 through the water outlet plate 7. The rolling brush 6 carries the hot water and rubs against the ground, so that the stubborn stains can be cleaned conveniently. After the hot water washing mode is started, the power of the battery pack 5 is converted into the heat energy of the heating tank 3, and the heating tank 3 is powered by the battery pack 5 (15-36V). The heating power is controlled to be 250-600W, so that the hot water can be generated and the power consumption can be effectively controlled. The hot water washing mode and the cold water washing mode can be quickly switched. In the normal ground state, the non-hot water washing mode is started to reduce the power consumption and prolong the washing time. In the abnormal ground state, the hot water washing mode is quickly switched to provide cleaning efficiency. During the non-use time of the machine, the battery is charged by using a charger, and the use and the charging do not interfere with each other.

[0029] As a preferred solution, the water pump 4 is provided with a water inlet pipe 41 and a water supply pipe 42. The heating tank 3 is provided with a water inlet 31 and a water outlet 32. The water inlet pipe 41 is connected with the water tank 2. The water supply pipe 42 is connected with the water inlet 31. The water outlet 32 is provided with a water outlet pipe 33, and the water outlet pipe 33 is connected with the water outlet plate 7. The water outlet 32 is provided with an electromagnetic valve for controlling the flow of the cleaning liquid in the heating tank 3. The water inlet 31 is arranged at the top of the side wall of the heating tank 3, and the water outlet 32 is arranged at the bottom of the side wall of the heating tank 3.

[0030] A method for controlling the hot water washing machine is provided. The control method comprises the following steps. Step A: determining the stain type of the cleaning position; Step B: determining the cleaning mode of the hot water washing machine based on the stain type; Step C: controlling the opening and closing of the water pump 4, the heating tank 3, the rolling brush 6, the electromagnetic valve and the main air blower 8 based on the cleaning mode.

[0031] Specifically, the stain types include a first stain category and a second stain category, the first stain category includes stubborn stains and oil stains, and the second stain category includes easy-to-clean stains such as dust and debris.

[0032] Specifically, step B further includes: if the stain type belongs to the first stain category, determining the cleaning mode of the hot water sweeper as a hot water washing mode; and if the stain type belongs to the second stain category, determining the cleaning mode of the hot water sweeper as a cold water washing mode.

[0033] Specifically, the hot water washing mode includes the following steps: Step 1: turn off the main fan 8, the roller brush 6, and the electromagnetic valve; Step 2: start the water pump 4 to fill the washing liquid in the water tank 2 into the heating tank 3; Step 3: heat the washing liquid in the heating tank 3 to a set temperature; Step 4: turn on the roller brush 6 and the electromagnetic valve, and run the main fan 8 at a first power, the heated washing liquid flows into the water outlet plate 7 through the water outlet pipe 33, and flows to the roller brush 6 through the water outlet plate 7.

[0034] Specifically, the cold water washing mode is to turn off the heating function of the heating tank 3 and run the main fan 8, the roller brush 6, and the electromagnetic valve at a second power.

[0035] Specifically, the set temperature in step 3 is 80-100 degrees.

[0036] The second power is greater than the first power, when the hot water washing mode is entered for the first time, the main fan 8, the motor of the roller brush 6, and the water pump 4 of the machine stop working, and the machine enters the washing mode only after the water temperature reaches the set temperature, so as to avoid heating while water is being discharged when the machine is started, so that the water temperature cannot be raised, and the hot water effect cannot be achieved. The power of the main fan 8 in the hot water washing mode is lower than that in the cold water washing mode, so as to reduce the total current consumption when working with the water heater, which is conducive to the endurance and stability of the battery pack 5.

[0037] The above description is only some of the preferred embodiments of the present disclosure and a description of the technical principles applied. Those skilled in the art should understand that the scope of the application involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or equivalent features without departing from the above inventive concept. For example, the above features and the technical features disclosed in the embodiments of the present disclosure (but not limited to) having similar functions are replaced with each other to form a technical solution.
