Description

  The present invention relates to a toilet seat device installed at the rear part of a Western-style toilet, and more particularly to a toilet seat device provided with a speaker on the rear surface.

  A case such as a toilet seat box is installed on the upper surface of the rear part of a Western-style toilet, and Western-style toilet equipment in which a toilet seat and a toilet lid are attached to the case so as to be rotatable in the up-down direction is widely used.

  Japanese Patent Application Laid-Open No. 2004-113388 describes a toilet seat device in which a speaker is provided on the rear surface of the case. In the toilet seat device disclosed in the publication, the rear surface of the case is inclined obliquely upward as described in paragraph 0011.

JP 2004-113388 A

  When installing a Western-style toilet in the toilet room, it is often desired to provide a large space in front of the Western-style toilet by arranging the Western-style toilet as far as possible.

  Therefore, the Western style toilet may be installed such that the rear end thereof is in contact with the toilet room wall behind the toilet. In this case, if a speaker is installed on the rear surface of the case such as a toilet seat box, the space between the speaker and the wall surface is small or not, so that the sound of the speaker is hardly transmitted to the outside. For example, the sound of a speaker is trapped in the case, resulting in poor sound quality.

  When the rear surface of the case is an upward slope as in JP-A-2004-113388, a relatively large gap exists between the rear surface of the case and the wall surface by increasing the inclination angle. The sound from the speaker on the rear side of the case can easily be transmitted to the toilet room through this gap.

  However, when the rear surface of the case is an upward slope as in JP-A-2004-113388, a large gap is visually recognized between the upper edge of the rear surface of the case and the wall surface of the toilet room. In addition, the dust, dust, small items, etc. easily enter the gap.

  In Japanese Patent Application Laid-Open No. 2004-113388, since the rear surface of the case is an upward slope, there is a risk that when water is applied to the case, the water will travel down the rear surface and come into contact with the speaker. In order to prevent this, as shown in FIGS. 5 to 7 of the publication, it is necessary to provide a protrusion on the upper side of the speaker installation portion in order to prevent water from being transmitted to the speaker.

  The present invention solves such problems, the sound from the speaker on the back of the case is easily transmitted to the toilet room, the water is not splashed on the speaker installation part, and the aesthetics in the toilet room is good. The purpose is to provide.

  The toilet seat device according to claim 1 is a toilet seat device including a case installed at a rear portion of a Western-style toilet and a toilet seat attached to the case, wherein a speaker installation portion is provided on a part of the rear surface of the case. The rearmost part located at the rearmost position is provided above the speaker installation part on the rear face of the case.

  The toilet seat device according to claim 2 is the toilet seat device according to claim 1, wherein a recess that is recessed forward is provided in a lower portion of the rear surface of the case, and the speaker installation portion is provided in the recess, The recess is characterized by being open toward the bottom or side of the case.

  A toilet seat device according to a third aspect of the present invention is the toilet seat device according to the first or second aspect, wherein the rearmost portion is an upper edge portion of the rear surface of the case.

  A toilet seat device according to a fourth aspect of the present invention is the toilet seat device according to any one of the first to third aspects, wherein the rear surface of the case has a slope inclined downward, and the speaker installation portion is located on the slope or below the slope. It is characterized by being arranged.

  The toilet equipment provided with the toilet seat device of the present invention has a rearmost part on the upper side of the speaker installation part on the rear surface of the case, and thus the rearmost part is installed so as to be in contact with or significantly close to the wall surface of the toilet room. Even in this case, a space portion is formed between the speaker installation portion on the rear surface of the case and the wall surface. Therefore, the sound from the speaker is easily transmitted into the toilet room through the space portion, and deterioration of sound quality is also prevented.

  In the present invention, since the rearmost part is located above the speaker installation part, even if water on the case falls down the rear surface of the case, it is difficult to get on the speaker installation part. When a concave portion is provided on the rear surface of the case and the speaker installation portion is provided in the concave portion, it is difficult for the speaker installation portion to be splashed with water, and dust is also difficult to adhere.

  By providing the rearmost part on the upper edge of the rear surface of the case and making this rearmost part abut or extremely close to the toilet room wall behind the toilet bowl, small items and dust can be found in the gap between the case rear surface and the toilet room wall. Water is prevented from entering. In addition, since there is no or almost no gap between the upper edge of the rear surface of the case and the wall surface of the toilet room, the appearance is good.
