Detailed ways

In order to clarify the technical problems, the technical solutions, and the technical effects achieved by the present invention, the technical solutions herein will be further described below with reference to the accompanying drawings.

In the related art, there is a case having an integral front side panel, that is, a plastic panel is omitted. The front side panel is fitted with a split hole in cooperation with the dispenser box. Since the dispenser box is generally of a drawer type structure, when the dispenser box is opened, the mating position of the front side panel and the dispenser box will be exposed, and the surface of the mating position is rough, which affects the appearance of the washing machine.

The embodiment provides a drum washing machine. As shown in FIG. 1 , the drum washing machine includes a box body, an outer tube disposed in the box body, and an inner tube rotatably disposed in the outer tube. The inner cylinder is driven to rotate by the driving assembly, and the clothes in the inner cylinder are continuously lifted and dropped, thereby washing the clothes with water and detergent.

The casing includes a front side panel 11, a rear frame 12, and an upper deck 13, and the front side panel 11 and the upper deck 13 are both connected to the rear frame 12. The door body 2 is provided on the front side panel 11. When the clothes need to be placed or taken out, the door body 2 is opened and the operation can be performed. The front side panel 11 is matched with the display screen, the distributor box 3, and the power control switch 6 by means of openings. Compared with the prior art cabinet, the control panel can be omitted, thereby reducing the number of parts of the drum washing machine. And the assembly gap on the outer surface makes the drum washing machine more beautiful.

In this embodiment, the front side panel 11 can be formed by metal pressing, that is, the front side panel 11 can be a sheet metal member, which is simple in forming and low in cost, and is integrated with the front side panel of the prior art. The gold member can enhance the strength of the front side panel 11, which is advantageous for improving the quality of the cabinet on the basis of reducing the cost of the drum washing machine.

In some embodiments, as shown in FIG. 2 and FIG. 3, the front side plate 11 is provided with a first mounting hole 112 and a second mounting hole 113. The first mounting hole 112 cooperates with the distributor box 3, and the second mounting hole 113 is embedded in the display panel 4. The front side plate 11 is further provided with a third mounting hole 114. The power control switch 6 is disposed in the third mounting hole 114, and the user controls the start and stop of the drum washing machine by pressing the power control switch 6. After the drum washing machine is started, relevant information is displayed through the display panel 4 to remind or guide the user to select an operation. In this embodiment, a notch is formed at a corner of one side of the upper end of the front side plate 11, and the notch forms a first mounting hole 112.

The middle portion of the front side panel 11 is recessed inwardly to form a mounting groove 111 for accommodating the door body 2. The mounting groove 111 communicates with the inside of the box body, and the door body 2 cooperates with the mounting groove 111 to open or close the door body 2 for pick-and-place Clothes or to ensure the safe operation of the drum washing machine. Wherein, the side walls of the mounting groove 111 are disposed obliquely such that the cross-sectional area of the mounting groove 111 gradually decreases from front to back.
