The heating device of the washing machine includes: a shell 100 and a heating component 200; specifically, the shell 100 is arranged at the bottom of the outer barrel, and the shell 100 is recessed to form a receiving cavity 300, which can accommodate more parts. The shell 100 is made of plastic and can be formed by injection molding. A water inlet 110 is arranged on the outside of the shell 100. In actual use, the water inlet 110 is connected to an external water source, such as a tap water pipe, etc., and the water flow from the outside can enter the heating component 200 through the water inlet 110, and the water inlet 110 is connected to the receiving cavity 300; the shell 100 is cylindrical as a whole, open upward, and the other surfaces are not closed. A plurality of connecting studs are arranged on the inner side surface of the top of the shell 100, which are distributed along the circumference of the shell 100, and the connecting studs are used to connect with the outer barrel to connect the shell 100 and the outer barrel.

[0035] For further information, please refer to Figure 1 The heating component 200 is arranged in the accommodating cavity 300, and is used for instantaneously heating the water flowing in from the water inlet 110. Optionally, the heating component 200 includes a ceramic heating tube, which can instantly heat the passing water when the water flows into the ceramic heating tube (the temperature can reach above 30 degrees), and the power can reach 1600-3000W. It should be understood that the heating component 200 can of course also use other electric heating tubes, and the present invention is not limited to this; the heating component 200 also includes other existing components not shown in the figure, such as power cords and other wires, which will not be described in detail in the present invention; at the same time, the heating component 200 is detachably connected to the surface of the shell 100, for example, the heating component 200 and the surface of the shell 100 are screwed or clamped to facilitate the heating component 200 replacement; the heating component 200 is provided with a water inlet pipe 210, the water inlet pipe 210 is a hose, and is detachably connected to the heating component 200 and the water inlet 110, the water inlet pipe 210 can be adapted to a narrow environment, and can be folded for use in the accommodating cavity 300, the water inlet pipe 210 is connected to the water inlet 110, and guides the water flow of the water inlet 110 into the heating component 200; wherein, the heating component 200 is provided with a water outlet 220 at one end away from the water inlet pipe 210, the water outlet 220 and the water inlet pipe 210 are respectively located at two ends of the heating component 200, and in actual use, the water outlet 220 is connected to the inner barrel of the washing machine, and is used to transport the hot water heated by the heating component 200 to the inner barrel through a pipeline to meet the hot water demand of the washing machine.

[0037] It is worth mentioning that when hot water is needed, the washing machine in the prior art adopts a heating method of first filling the inner barrel with water, and then starting the heating device between the inner barrel and the outer barrel after the filling is completed. This method requires waiting for a period of time. In the present invention, a heating component 200 is added to the water inlet 110, so that the water flow can be heated in time when hot water is needed, so that the water flow can achieve the hot water effect before reaching the inner barrel, thereby greatly shortening the heating time of the water flow and facilitating the use of users.

[0038] For further solutions, please refer to Figure 1, the heating device of the washing machine also includes: a water inlet valve 400 and a pressure-stabilizing valve 500; wherein, the water inlet valve 400 is arranged in the accommodating cavity 300, and is detachably connected to the surface of the shell 100, for example, by screws or other threaded connections, so as to facilitate the maintenance and replacement of the water inlet valve 400, and the water inlet valve 400 is connected to the water inlet 110; by arranging the water inlet valve 400 at the water inlet 110, the water flow can be cut off in time to avoid the impact of the heating component 200 when the water flow is unstable, thereby preventing the heating component 200 from being damaged; further, the pressure-stabilizing valve 500 is arranged in the accommodating cavity 300, and is detachably connected to the surface of the shell 100, for example, by screws or other threaded connections, To facilitate the maintenance and replacement of the pressure-stabilizing valve 500; wherein the pressure-stabilizing valve 500 is connected to the water inlet valve 400 and the water inlet pipe 210 respectively, and is used to stabilize and regulate the water flow delivered by the water inlet valve 400 and then deliver it to the water inlet pipe 210, and then deliver it to the heating component 200.
