BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outdoor doorphone slave unit which is connected to an indoor master unit and communicates with the master unit.

[0002]

2. Description of the Related Art FIG. 6 is a front view showing a conventional door phone handset, and FIG. 7 is a sectional view taken along line XX of FIG. 2. Description of the Related Art Conventionally, various types of doorphone slave units are known, and as a design-oriented one, as shown in FIG.
A plurality of grooves 5, 5,... Extending in the horizontal direction in the normal mounting posture are arranged in parallel on the surface of the housing 4, and an audio output groove 6 is provided on the upper side 5a of the groove 5 as shown in FIG. , A speaker (not shown) is disposed on the back side of the housing 4 so as to cover the audio output grooves 6, 6,.
There is known a door phone handset which outputs an output sound from a speaker to the outside of a housing 4 via 6,. With this configuration, it is possible to prevent rainwater from entering the back side of the housing 4 from the sound output groove 6 and destroying electric components such as speakers inside the housing 4.

[0003]

However, as shown above, the doorphone slave device provided with the concave grooves 5, 5,... In the horizontal direction tends to allow rainwater to collect in the concave grooves 5 due to surface tension or the like.
In some cases, the rainwater blocks the sound output groove 6 and interrupts the sound output from the speaker, resulting in a decrease in the volume of the output sound.
In order to make such a situation unlikely to occur, the width of the concave groove may be increased, but there is a problem in that the design is impaired.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a door phone handset having a structure in which water hardly accumulates in a groove regardless of the width of the groove in the horizontal direction. To provide.

[0005]

Means for Solving the Problems The present invention made to solve the above problems is an outdoor door phone handset which is connected to an indoor base unit and communicates with the base unit. A plurality of grooves extending horizontally in the normal mounting posture of the doorphone handset are arranged in parallel on the housing surface, and an audio output groove is provided on the upper side of each groove in the normal mounting posture of the doorphone handset. A doorphone slave unit, wherein a speaker is disposed on the back side of the housing so as to cover the plurality of audio output grooves, and the output sound from the speaker is output to the front side of the housing via the audio output grooves. A through hole is provided in a part of the lower side of the groove when the container is in a normal mounting posture , and the through hole communicates the groove with the lower groove .

[0006]

In the present invention, when water accumulates in the groove, it travels along the groove, is guided to the through hole provided in the groove, and falls downward through the through hole. At that time, the water that has fallen into the lower groove passes through the through hole in that step and further falls into the lower groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing embodiments thereof.

FIG. 2 is a front view showing one embodiment of the door phone slave 1 according to the present invention, and is a front view of the housing 4 which is one configuration of the door phone slave 1. FIG. 3 is a rear view of the housing 4. As shown in FIG. 2, a plurality of grooves 5, 5,... Extending horizontally in the normal mounting posture of the intercom slave 1 are provided on the surface of the housing 4 as shown in FIG. Are installed side by side. still,
Reference numeral 2 denotes a camera window arranged in front of the monitor camera, and reference numeral 3 denotes a call button operated by a visitor.

FIGS. 1, 4 and 5 show the detailed structure of the plurality of grooves 5, 5,... FIG. 4 shows the structure of the plurality of grooves 5, 5,. FIG. 5A is an enlarged view of a back side portion, and FIG.
(B) is a BB side sectional view in FIG. 3. Also, FIG.
FIG. 3 is a sectional perspective view taken along line FF in FIG. 2.

In the door phone handset 1 of the present embodiment, as in the prior art, an audio output groove 6 is provided in a large part of the upper side portion 5a of each groove 5 when the door phone handset 1 is in a normal mounting posture. A speaker (not shown) for outputting sound from a parent device (not shown) or the like is fixedly disposed on the back side of the housing 4 so as to cover the plurality of sound output grooves 5, 5,. The audio output from the speaker is output to the front side of the housing 4 through the audio output grooves 5, 5,. The speaker is shown in FIG.
It is fixed in the round frame of the part where 5,... Each of the audio output grooves 6, 6,... Is arranged in a matrix with a plurality of columns 7 interposed therebetween.

[0011] Further, the door phone slave device 1 of the present embodiment is shown in FIG.
And as shown in such FIG. 5, a portion of the lower side 5c of the groove 5 in the normal mounting position of the intercom slave unit 1, the concave
A through hole 5d that connects the groove 5 with the lower concave groove 5 is provided.

The dashed line arrow in FIG. 5A indicates the flow of water accumulated in the concave groove 5. In the doorphone slave device 1 having the above-described configuration, when water collects in the concave groove 5, the water passes through the concave groove 5 in the direction of the dashed line arrow in FIG.
d, and as shown in FIG.
d, and falls into another concave groove 5 below. At that time, the water that has fallen into the lower groove 5 at the lower stage is guided by the through hole 5d at that stage, and falls through the through hole 5d to another lower groove 5 further below. This prevents water from accumulating in the groove 5 and blocking the sound output groove 6. Further, as the flow of water accumulated in the concave groove 5, there is a flow passing through the inside of the concave groove 5 as well as a flow passing through the inside of the concave groove 5 as shown in FIG.

Incidentally, in the door phone slave unit of the present embodiment,
As shown in FIG. 1, a plurality of through-holes 5d, 5d,... Are provided in a state of being arranged in the vertical direction, so that water accumulated in the concave groove 5 flows down more smoothly. However, the position where the through hole 5d is provided may be any position as long as it is in the lower side 5c of the concave groove 5.

[0014]

According to the present invention constructed as described above, the structure is such that water hardly accumulates in the groove regardless of the width of the groove in the horizontal direction, and water such as rainwater closes the sound output groove and flows from the speaker. A good sound output can always be obtained without interrupting the sound output.
