However, the control of the household appliances generally only needs some simple commands, and a more appropriate mode is to solidify the command entries in a local storage after algorithm training and model matching, and when voice control is performed, direct calling processing is realized locally without depending on the internet. Compared with an online processing mode, the stability and efficiency of offline speech recognition are higher. If the network has problems, the voice interaction function can still keep the working state, the time delay of the recognition process is small, and the user experience is good.

For washing machines, the voice module is typically disposed in the cabinet, adjacent to the control module. The pickup hole of the microphone is arranged on the surface of the box body. By adopting the structure, factors such as noise, reverberation, human voice interference, echo and the like in the real environment cause larger influence, the signal to noise ratio of a recorded signal is very low, the algorithm processing difficulty is increased, and especially for offline voice recognition, the recognition effect is further weakened due to the limited operational capability of a control chip. In addition, since the washing machine inevitably contacts the surface of the cabinet with the washing water during use, the microphone disposed on the surface of the cabinet may be out of order, and the stability of the apparatus may be reduced.

The washing machine door assembly 102 according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings. As shown in fig. 1, 2, 9 and 15, the washing machine door assembly 102 includes an outer frame 102-2 and an inner frame 102-3 disposed around the edges of the viewing window assembly, the outer frame being removed in fig. 2 in order to more clearly illustrate the internal structure of the washing machine door assembly. Generally, the glass 102-1 and bezel (not shown) of the viewing window assembly are sandwiched between the outer frame 102-2 and the inner frame 102-3. The outer frame 102-2 and the inner frame 102-3 are preferably snap-fit connected. The washing machine door assembly 102 is rotatably coupled to the cabinet 101 of the drum washing machine by a door hinge assembly 103 to open or close an access opening for taking and putting laundry, which is provided on the cabinet 101. Unlike the prior art, in the present invention, a supporting cavity 105 for fixedly mounting the voice module 104 is further formed between the outer frame 102-2 and the inner frame 102-3, and the voice module 104 is fixedly disposed in the supporting cavity 105. The voice module 104 is connected to a control module 110 disposed on the housing 101 through a wire. The voice module 104 is arranged in the washing machine door assembly 102, so that a pickup hole of a microphone is prevented from being formed in the surface of the box body 101, and on one hand, the influence of noise, reverberation, human voice interference, echo and other factors in the real environment on voice recognition can be reduced; on the other hand, the voice module can be effectively prevented from contacting with washing water, the working stability of the voice module is improved, and the service life of the voice module is prolonged.

Specifically, the outer frame 102-2 and the inner frame 102-3 are each circular. The inner frame 102-3 has a first inner frame surface 102-31 and a second inner frame surface 102-32.

For the convenience of assembly, the upper edge of the front plate 101-2 of the case 101 is provided with a flange 101-25 extending in the same direction as the front plate 101-2 of the case 101. In a non-assembly state, the flanging 101-25 forms a certain included angle with the front plate 101-2 of the box body 101. Preferably, the included angle is 5 degrees. The front beam 108 includes a beam body 108-1 and a connecting portion 108-2, the beam body 108-1 and the connecting portion 108-2 are perpendicular to each other, and the extending direction of the connecting portion 108-2 is opposite to the extending direction of the front plate 101-2 of the box 101. During assembly, the left end and the right end of the beam body 108-1 are fixedly connected with the box body 101-1 through bolts, and then the connecting part 108-2 extends into the area between the flanging 101-25 and the front plate 101-2 of the box body 101, namely the front plate 101-2 of the box body 101 is hung on the front beam 108 and is fixed through the bolts, and the assembly is completed. In this way, the sheet metal integrated front plate is suspended on the front cross member 108. After the suspension is finished, the flanging is basically parallel to the front plate 101-2 of the box body 101, so that the suspension effect is stable and reliable.

Because the front plate 101-2 of the box body 101 is designed in a metal plate integrated manner, sound pickup holes are protected at the same time in order to achieve a better sound pickup effect. In the present embodiment, the speaker and the microphone connected to the voice module 104 are both disposed in the support cavity 102-5; the speaker through hole 111-2 and the microphone sound pickup hole 111-1 are provided on the first inner frame surface 102-31. Preferably, a microphone array 111 is provided in the support cavity 105 to optimize the sound pickup effect of the speech module 104. The microphone array 111 may be a linear array that can resolve sound source information within 180 degrees or a circular array that can resolve sound source information within 360 degrees. For the drum washing machine, generally, the probability that the sound source information comes from below is small, and therefore, it is preferable to provide a linear array, and symmetrical microphone sound-collecting holes 111-1 corresponding to the linear array are provided on the first inner frame surface 102-31. The voice module 104 is preferably disposed at a position above a centerline of the door assembly 102 of the washing machine, and the display control module 110 is disposed in the cabinet 101 at a corresponding position. In this way, the inner frame and the front plate 101-2 of the box body 101 may form a sound-collecting cavity, and in order to ensure the sealing effect, a sealing strip is usually further disposed in the sound-collecting cavity in a matching manner. The sound inlet of the pickup cavity is formed at the gap between the door assembly 102 of the washing machine and the front plate 101-2 of the cabinet 101, and is highly ergonomic. In a more preferred form, a trim strip 110 is provided at the sound inlet, the trim strip having a guide hole therein, the guide hole being blind. The guide hole does not have the effect of really picking up sound, but guides the user to make a sound towards the area, and the using effect of the voice module 104 is guaranteed. And the function of beautifying the appearance is achieved.

The utility model discloses a drum washing machine, which improves the working stability of the voice module through the connection mode of the specially designed voice module and the control module while ensuring the concise appearance; after the connecting structure is added, the control module can be conveniently and mechanically and electrically connected with other functional parts in the box body, and the normal opening and closing of the door body cannot be influenced. The utility model discloses a drum type washing machine has that job stabilization nature is high, the practicality is good, and the pleasing to the eye advantage of appearance.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
