Control failure affects the user experience. On the other hand, the sound pickup cavity enclosed by the inner frame, the sealing strip, the inner frame and the guide wall is a semi-sealed chamber with only one sound entrance (the dotted arrow in Figure 4 shows that the voice signal enters the sound pickup space). The path of the cavity), the length of the pickup cavity is short, and the attenuation of the voice signal is reduced, so it has a good pickup effect, which can avoid the influence of noise, reverberation, vocal interference, echo, etc. in the real environment, and improve the recording The signal-to-noise ratio of the signal further improves the control effect. Third, the blind hole on the decorative strip set at the sound entrance can play a guiding role, guiding the user to output the voice signal to the sound pickup cavity, and further ensuring the use effect of the voice module.

As shown in Figures 7 and 8, in the drum washing machine with a concealed radio structure disclosed in the present invention, a guide wall 102-6 is symmetrically provided on the second inner frame surface 102-32, and the guide wall 102-6 protrudes On the second inner frame surface 102-32 and extending along the axial direction of the second inner frame surface 102-32, the wire 105 connected to the voice module 104 is arranged between the guide walls 102-6. The guide wall 102-6 is arranged on the surface 102-32 of the second inner frame. On the one hand, it can ensure the stable connection between the voice module 104 and the control module 110, and improve the stability of the voice module 104. The cavity may also be provided with an image recognition module, a distance recognition module, and other biological recognition modules. The guiding wall 102-6 can prevent the wires between the voice module 104 and the control module 110 from causing interference with other functional modules; at the same time, the guiding wall 102 -6 can also increase the strength of the inner frame 102-3.

During the washing process of the drum washing machine, the washing machine door assembly 102 opens or closes relative to the cabinet 101. Therefore, the wire will shift to a certain extent and wear out after long-term use. In order to reduce the wear of the wire, in this embodiment, the guide wall 102-6 is intermittently arranged, and the intermittently arranged guide wall 102-6 and the second inner frame surface 102-32 jointly enclose the first wire groove 102-33, thereby The contact area between the wires and the first wire grooves 102-33 is reduced. The width of the first wire groove 102-33 is greater than the diameter of the wire, preferably 1.5 to 2 times the diameter of the wire. On the one hand, the first wire trough 102-33 composed of intermittently arranged guide walls 102-6 can play a role in guiding the wire. On the other hand, the first wire trough 102-33 also provides a certain buffer space for the wire. It is not prone to wear when used for a long time, which further ensures the safety of the voice module 104 in use. At the same time, the intermittently arranged guide wall 102-6 can also save the space of the supporting cavity, and facilitate the further expansion of the washing machine functional module.

In order not to block the hinge assembly, the inner frame 102-3 is provided with an opening 130 that allows the door hinge assembly 103 to pass through. In order to guide the wire to change direction and enter the hinge assembly, the guide wall 102-6 is intermittently arranged to sequentially form a first wall section 102-331, a second wall section 102-332, and a third wall section 102-333. The first wall sections 102-331 are distributed in an arc shape and are formed between the voice module 104 and the door hinge assembly 103, and are used to guide the wire 105 connected to the voice module 104 to extend along the second inner frame surface 102-32 to avoid The wire and the observation window glass 102-1 overlap, and the second wall sections 102-332 are approximately vertically distributed along the top-down direction, and are formed on one side of the opening 130 to avoid interference between the wire and the hinge body. The three-wall sections 102-333 are formed under the opening 130, and are used to guide the wire to change the extending direction into the hinge body, and pass through the front panel of the box body 101 through the hinge body. Preferably, the lengths of the first wall section 102-331, the second wall section 102-332, and the third wall section 102-333 are decreasing to form the length of the guide wall 102-61 of the first wall section 102-331 The length of the guide wall 102-62 constituting the second wall section 102-332 is smaller than the length of the guide wall 102-62 constituting the second wall section 102-332 is smaller than the length of the guide wall 102 constituting the third wall section 102-333 -63 length, this design takes into account that the bending degree and the number of bending of the wire in the second wall section and the third wall section are significantly larger than the first wall section, and the increasing length can ensure that the wire does not fall off .

The wire 105 is laid and extended along the first wire trough 102-33 until the door hinge assembly 103 is located. The hinge body 103-1 passes through the opening 130 and protrudes from the second inner frame surface 102-32. The hinge body 103-1 is formed with a first cavity 109 that guides and changes the extension direction of the wire 105, and the first cavity 109 communicates with The first through hole 101-27 is opened on the front plate 101-2 of the box body 101, the wire 105 enters the first cavity 109 in the hinge body 103-1 from bottom to top, and is guided through the first through hole 101-27 After passing through the front plate 101-2 of the box body 101, it enters the second wire groove 107-1 from bottom to top, and is connected to the control module 110 provided in the box body 101.

In this way, the rotation of the washing machine door assembly 102 relative to the cabinet 101 will not affect the connection between the voice module 104 and the control module 110, and the wire 105 between the two is completely hidden and invisible, and will not affect the whole washing machine. Or increase the number of external parts of the washing machine box 101. The working environment of the voice module 104 is stable. At the same time, the control module 110 can conveniently form good mechanical and electrical connections with other control components, display components, buttons, etc.
