(Embodiment 1)
FIG. 1 is an external perspective view and a main part plan view of a washing machine according to Embodiment 1 of the present invention. FIG. 1B is an enlarged view of A shown in FIG. FIG. 2 is a sectional side view of the main part of the speaker of the washing machine. FIG. 3 is a sectional side view of a main part of the speaker housing portion of the washing machine. FIG. 4 is a partial cross-sectional view of the interference relationship between the speaker housing portion and the front panel of the washing machine.

  In FIG. 1, an upper cover 5 is placed above the main body 1. A front wall 20 is provided on the front side of the main body 1. An openable / closable lid 4 is provided on the front side of the main body 1 and in the center of the front wall 20.

  Above the front side of the main body 1 is provided an operation panel 2 for operating and displaying the washing machine. The operation panel 2 is provided on the top of the front wall 20 and on the front side of the upper cover 5 so as to be inclined so that the operation side is upward. A water supply hose 3 connected to a water supply valve for supplying washing water is piped at the rear of the upper cover 5. The water supply hose 3 is connected to a water supply faucet 6 installed on the wall 7 of the rear house.

  The user opens and closes the lid 4 and puts clothes in and out of the washing machine. Further, the user can input an operation signal to the control device by operating the operation panel 2 and can confirm the operation state and the setting state. At this time, guidance, cautions, and the like are notified by sound together with the display, so that the configuration is excellent in ease of use with few erroneous operations.

  As shown in FIG. 2, a speaker housing portion 9 that houses the speaker 8 is provided on the back side, which is the back side of the operation panel 2. The speaker housing unit 9 houses a speaker 8 that generates sound and sound. The sound from the speaker 8 is emitted from the fitting gap between the operation panel 2 and the upper cover 5, the operation panel 2 and the front wall 20 as indicated by arrows D 1 and D 2. The speaker housing 9 is composed of two or more members. That is, the speaker housing part 9 has a first housing case 9a and a second housing case 9b. The first housing case 9 a to which the speaker 8 is attached is fixed to the second housing case 9 b from the rear of the speaker 8. The second housing case 9 b is fixed to the operation panel 2 with screws 17 and claws 12.

  The fitting portion 9c of the first housing case 9a and the second housing case 9b is provided with a first rib 9d and a second rib 9e that enter each other. Therefore, the fitting part 9c is formed in steps. As shown in FIG. 3, the fitting portion 9c has a structure with higher confidentiality because the first rib 9d and the second rib 9e that protrude from each other are in contact with the first bottom portion 9f and the second bottom portion 9g on the mating side. . That is, the 1st rib 9d of the 1st storage case 9a contacts the 2nd bottom part 9g of the 2nd storage case 9b. The second rib 9e of the second housing case 9b is in contact with the first bottom portion 9f of the first housing case 9a. With the above configuration, the fitting portion 9c has a highly confidential structure that is more easily contacted.

  Furthermore, the fitting portion 9c includes a first inclined surface 9h that is inclined from the first rib 9d to the first bottom portion 9f. Similarly, the fitting portion 9c includes a second inclined surface 9i that is inclined from the second rib 9e to the first bottom portion 9g. The first inclined surface 9h and the second inclined surface 9i are not in contact with each other. For this reason, the fitting part 9c has the space part formed of a bottom part, an inclined surface, and a rib. Moreover, the fitting part 9c is comprised by step shape, and is not a linear confidential structure. For this reason, the fitting part 9c has a structure in which sound is hardly leaked. Therefore, a sound is accumulated in the speaker housing portion 9, and the sound can be delivered in the direction in which the sound is delivered. As a result, it is possible to make the user recognize the sound without providing a sound emitting hole.

  The mounting structure of the speaker 8 will be described below with reference to the partial cross-sectional view of FIG.

  In FIG. 4, the speaker 8 includes a diaphragm (cone paper) 14 that generates sound. The diaphragm 14 is disposed so as to face downward on the rear side. The speaker 8 is provided such that the diaphragm 14 is located on the back side and below the speaker 8. As a result, a sound trapped in the rear space 10 formed by the diaphragm 14 and the speaker housing portion 9 is emitted downward toward the rear of the main body 1 as indicated by an arrow S. The second housing case 9b covers the speaker 8 from the front side toward the back side. The second housing case 9b is fixed to the first housing case by screws 11 from the outside that is the front.

Hereinafter, the mounting configuration of the speaker 8 and the first housing case 9a will be described.
The speaker 8 is provided with an opening 13 serving as an open portion facing downward on the back side. A diaphragm 14 is attached to the part facing the opening 13 in an inclined manner.

  The first housing case 9a is made of, for example, a plastic molded product. The outer peripheral portion of the speaker 8 is engaged with the L-shaped locking piece 15b formed integrally with the peripheral portion. An L-shaped protrusion 15 a formed at a position approximately 180 ° opposite to the speaker 8 engages the outer peripheral portion of the other end of the speaker 8.

  As a result, the speaker 8 and the first housing case are assembled in the previous step, and then fixed with screws 11 from the rear side of the speaker 8 as shown in FIG. Therefore, as shown in FIG. 2, since the speaker 8 is held substantially parallel to the operation panel 2, the diaphragm 14 has a configuration in which the angle is substantially parallel to the opening 13 of the first housing case 9a.

  The fitting portions 9c of the first housing case 9a and the second housing case 9b are formed in a stepped shape, and are further prevented from being lifted by being locked by three claws 18 and screws 11. Thereby, it is sealed so that sound does not leak from the rear space 10 with a simple configuration.

  In FIG. 5, two protrusions 16 are provided in the second housing case 9 b. The protrusion 16 has an interference relationship with the operation panel 2 and is pressed against the operation panel 2. About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

The sound generated from the diaphragm 14 of the speaker 8 is magnified in the rear space 10 and emitted as indicated by an arrow S shown in FIG. As indicated by arrows D1 and D2, it is transmitted to the outside of the machine through a fitting gap between the operation panel 2, the upper cover 5, and the front wall 20 .

  Moreover, the speaker 8 is disposed so as to be substantially parallel to the operation panel 2 and is attached so as to be directed to the opposite side facing downward and rearward. Therefore, even if water or the like enters from the fitting gap around the operation panel 2, the possibility of entering the speaker 8 is reduced.

  As described above, in the present embodiment, since no sound emitting hole is provided in the operation panel 2, water and detergent can be prevented from entering, and the sound generating diaphragm 14 faces away from the operation panel 2. The possibility of external damage can be reduced.

  Furthermore, since no sound emission holes are provided in the operation panel 2 and sound is emitted to the rear of the operation panel 2, water intrusion from the sound emission holes can be completely prevented. There is no such thing as to do. In addition, there is no unsafe situation of insulation deterioration of electrical members such as the speaker 8, and stable sound notification can be performed. Moreover, since it is the structure by which a sound emission hole is not provided, it becomes a washing machine with the outstanding external appearance.

  Further, the protrusion 16 is provided on the second housing case 9b of the speaker housing 9 and pressed against the operation panel 2 in an interference relationship, thereby reducing vibration. Therefore, abnormal noise due to vibration is prevented.

  Furthermore, the size and airtightness of the rear space 10 are important for securing the sound pressure of the speaker. The fitting portions 9c of the first storage case 9a and the second storage case 9b are formed in a step shape, and the claw 18 and the screw 11 prevent the storage case from floating. For this reason, the rear space 10 with high airtightness is formed.

  Further, the outer periphery of the rear space 10 is larger than the outer periphery of the speaker 8. Since the rear space 10 is configured to be larger than the speaker 8, it is easy to ensure sound pressure by the resonance of sound in the rear space 10. From the above, even if the speaker 8 is small, and even if the sound emission hole is not provided on the operation panel 2, the function of the speaker 8 is sufficiently exhibited.

  As described above, the sound notification configuration of the washing machine makes it easy for the user to recognize the sound notification and prevents the intrusion of water and foreign matter from the outside. Pressure can be secured.

(Embodiment 2)
FIG. 6 is an enlarged view of a main part of the fitting portion of the speaker housing portion of the washing machine according to the second embodiment of the present invention. The shape of the fitting part 9c of the speaker accommodating part 9 differs from Embodiment 1. FIG. The other embodiments use the first embodiment. Hereinafter, different points will be described.

  The fitting portion 59c of the first storage case 59a and the second storage case 59b is provided with a first rib 59d and a second rib 59e that enter each other. Therefore, the fitting part 59c is formed in a staircase shape. As shown in FIG. 3, the fitting portion 59c has a structure with higher confidentiality because the first rib 59d and the second rib 59e that protrude from each other come into contact with the first bottom portion 59f and the second bottom portion 59g on the other side. . That is, the first rib 59d of the first housing case 59a contacts the second bottom 59g of the second housing case 59b. The second rib 59e of the second housing case 59b contacts the first bottom 59f of the first housing case 59a. With the above configuration, the fitting portion 59c has a highly confidential structure that is more easily contacted.

  Furthermore, the fitting part 59c includes a first orthogonal surface 59h orthogonal to the first rib 59d and the first bottom part 59f. Similarly, the fitting portion 59c includes a second orthogonal surface 59i that is orthogonal from the second rib 59e to the first bottom 59g. The first orthogonal surface 59h and the second orthogonal surface 59i are not in contact with each other. For this reason, the fitting part 59c has a space part formed by a bottom part, an orthogonal surface, and a rib. Moreover, the fitting part 59c is comprised in step shape, and is not a linear confidential structure. For this reason, the fitting part 59c has a structure in which sound is hardly leaked. Therefore, sound is accumulated in the speaker housing portion 59, and the sound can be delivered in the direction in which the sound is delivered. As a result, it is possible to make the user recognize the sound without providing a sound emitting hole.

  As described above, since the washing machine according to the present invention can prevent a foreign matter from being arranged by arranging the speaker on the front surface of the device, it is also useful for household devices that perform voice notification.
