Abstract

(57) [Abstract] [Purpose] An intercom handset having a structure in which water is unlikely to collect in the concave groove 5 regardless of the width of the concave groove 5 extending in the horizontal direction and having the audio output groove 6 for outputting a sound from a speaker. provide. [Structure] A through hole 5d that connects the front and back of the housing 4 is provided in a part of the lower side portion 5c of the concave groove 5 when the intercom subunit 1 is normally mounted. When water collects in the groove 5, it is guided along the groove 5 in the direction of the one-dot chain line in FIG. 1 to the through hole 5d, and the water passes through the hole 5d to form another groove below. Fall to 5. At this time, the water that has dropped into the lower groove 5 is guided by the through hole 5d in that step, passes through the through hole 5d, and further drops into another groove 5 below. This prevents water from accumulating in the groove 5 and blocking the audio output groove 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an intercom subunit installed outdoors that is connected to an indoor master unit and is capable of communicating with the master unit.

[0002]

[Prior art]

 FIG. 6 is a front view showing a conventional intercom subunit, and FIG. 7 is a sectional view taken along line XX of FIG. Although various types of intercom subunits are conventionally known, as shown in FIG. 6, a plurality of recessed grooves 5 that extend horizontally when the intercom subunit 1 is normally mounted are given particular importance to the design. , 5, ... are arranged side by side on the surface of the housing 4, and an audio output groove 6 is provided on the upper side portion 5a of the concave groove 5 as shown in FIG. There is known an intercom sub unit which is disposed on the back side of the housing 4 so as to cover the housing 4, and outputs the sound output from the speaker to the outside of the housing 4 through the sound output grooves 6, 6 ,. With this structure, rainwater does not enter the back side of the housing 4 from the voice output groove 6 and the electric parts such as the speaker inside the housing 4 are not destroyed.

[0003]

[Problems to be solved by the device]

 However, as described above, the doorphone device provided with the concave grooves 5, 5, ... In the horizontal direction easily collects rainwater in the concave groove 5 due to surface tension or the like, and the rainwater blocks the audio output groove 6 from the speaker. The output sound of the output sound was interrupted and the volume of the output sound was lowered. In order to make such a situation less likely to occur, the width of the concave groove may be widened, but there is a problem that the designability 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 doorphone subunit having a structure in which water is unlikely to collect in the groove regardless of the width of the groove in the horizontal direction. To provide.

[0005]

[Means for Solving the Problems]

 The present invention, which has been made to solve the above-mentioned problems, is an outdoor doorphone subunit that is connected to an indoor master unit to communicate with the master unit, and the doorphone subunit is normally installed. A plurality of horizontally extending recessed grooves are provided on the housing surface in the posture, and a voice output groove is provided on the upper side of each recess when the doorphone subunit is normally mounted. An intercom sub unit that is placed on the back side of the housing so as to cover the groove and outputs the sound output from the speaker to the front side of the housing via the above-mentioned audio output groove. It is characterized in that a through hole that connects the front side and the back side of the housing is provided in a part of the lower side portion of the above-mentioned concave groove.

[0006]

[Action]

 In the present invention, when water collects in the groove, it travels along the groove, is guided by the through hole provided in the groove, and drops downward through the through hole. At this time, the water that has dropped into the lower groove is further dropped into the lower groove through the through hole of that step.

[0007]

【Example】

 The present invention will be described below with reference to the drawings showing an embodiment thereof.

FIG. 2 is a front view showing an embodiment of the intercom subunit 1 according to the present invention, and is a front view of a housing 4 which is one configuration of the intercom subunit 1. Further, FIG. 3 is a rear view of the housing 4. As shown in FIG. 2, the intercom subunit 1 of the present embodiment has a plurality of recessed grooves 5, 5, ... Which extend in the horizontal direction when the intercom subunit 1 is normally mounted, as in the conventional example. Lined up on the surface. Incidentally, 2 is a camera window arranged directly on the monitor camera, and 3 is a call button operated by a visitor.

1, 4 and 5 are views showing a detailed structure of the plurality of recessed grooves 5, 5, ..., FIG. 4 shows the plurality of recessed grooves 5, 5 ,. 5A is an enlarged view of a back side portion, FIG. 5A is a sectional view taken along line AA in FIG. 3, and FIG. 5B is a sectional view taken along line BB in FIG. 1 is a perspective view taken along the line FF in FIG.

The doorphone subunit 1 of the present embodiment is provided with an audio output groove 6 in most of the upper side portions 5a of the respective recessed grooves 5 when the doorphone subunit 1 is normally mounted as in the conventional case. A speaker (not shown) for outputting a sound from a parent device (not shown) of the above is fixedly arranged on the back side of the housing 4 so as to cover the plurality of voice output grooves 5, 5 ,. Output sound from the speaker is output to the front side of the housing 4 via the plurality of sound output grooves 5, 5, .... The speaker is fixed in a circular frame of a portion where a plurality of concave grooves 5, 5, ... Are gathered in FIG. The plurality of audio output grooves 6, 6, ... Are arranged in a matrix with the column portion 7 interposed therebetween.

Further, as shown in FIG. 1 and FIG. 5, the intercom subunit 1 of this embodiment has a housing at a part of the lower side portion 5c of the concave groove 5 when the intercom subunit 1 is normally mounted. A through hole 5d that connects the front and back of No. 4 is provided.

The dashed-dotted line arrow in FIG. 5A indicates the flow of water accumulated in the groove 5. In the intercom subunit 1 having the above structure, when water accumulates in the concave groove 5, the water is guided along the concave groove 5 in the direction of the one-dot chain line in FIG. As shown in (), the water drops through the through hole 5d and into another groove 5 below. At this time, the water that has dropped into the lower groove 5 is guided by the through hole 5d in that step and further drops through the through hole 5d to another groove 5 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 shown in FIG. 5A, and also a flow passing through the back side of the concave groove 5.

In the intercom subunit of the present embodiment, as shown in FIG. 1, a plurality of through holes 5 d 1, 5 d, ... Are provided in a line in the vertical direction, and the through holes 5 d 1, 5 d are accumulated in the concave groove 5. Although the water flows down more smoothly downward, the position where the through hole 5d is provided may be any position as long as it is within the lower side portion 5c of the concave groove 5.

[0014]

[Effect of device]

 According to the present invention configured as described above, regardless of the width of the groove in the horizontal direction, the structure is such that water is unlikely to collect in the groove, and water such as rainwater blocks the audio output groove and interferes with audio output from the speaker. It is possible to always obtain a good audio output.
