Abstract

(57) [Summary] [Problem] A portable small ventilation device that can be freely carried in a toilet without being fixed to a ceiling surface, a wall surface, or a window and requires no installation work. The power supply is an AC power supply, a DC power supply, a battery,
Uses batteries, incorporates a small, lightweight, well-ventilated fan into a small box, ornament, or decoration, ventilates by opening the front and back of the fan, operating with a sensor or manual switch, and placing it near the toilet window. It is a portable small ventilator that has a deodorizing effect.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a ventilating deodorizing device for removing odorous gas in a toilet room.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, two types of toilet deodorizing devices have been employed. 1) is a ventilation deodorizer with a ventilation fan. 2) is an air purifier type deodorizing device using a filter, a catalyst, and the like.

[0003]

[Problems to be solved by the invention]

 Of those described in the prior art, 1) deodorization by a ventilation fan must be used by fixing it to the ceiling surface, wall surface, or window frame in the toilet room. Therefore, it is easy to install a new house, but for existing houses, there are various restrictions on the construction of ceilings and walls, resulting in higher construction costs.

The method of fixing to a window frame according to the conventional technique 1) has a structure that covers a part of the window or the entire vertical direction, and the original function of the window such as lighting is limited.

[0005] The air purifier type deodorizing device of the prior art 2) requires maintenance such as inspection and replacement of the filter and the catalyst, so that the troubles during normal times remain.

[0006]

[Means for solving the problem]

 The portable small ventilation device for toilet in the present invention can be freely installed anywhere without any installation work, and is intended to perform the original toilet ventilation and deodorization.

[0007] In order to achieve the above object, the portable small ventilator for toilet of the present invention is operated by AC power supply or DC power supply, or battery or battery, and is small, thin, light and sufficiently ventilated air volume. The built-in fan is installed in a small and light box, ornament, or decoration, and is operated by AC power or DC power, or a battery, or a battery. As a result, the portable small ventilator for toilets of the present invention can easily achieve its purpose simply by placing it near an open window without fixing it to a ceiling surface, a wall surface, or a window. It does not hinder the original lighting.

[0008]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. Incorporate a small and lightweight box into the ornament or decoration, or place the small and lightweight box itself near the open toilet window. When a person enters the toilet, the fan is rotated by the human infrared sensor of (2), the odor sensor of (2), the light sensor of (2), or the manual switch of (3). After using the toilet, ventilate the odor with the preset electronic timer or the manual switch (3) and then stop.

[0009]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained.

The fan incorporated in a small and lightweight box has a sufficient ventilation airflow (for example, a maximum airflow of 2 to 2.5 m ³ / min) to deodorize within the time operated by an electronic timer or a manual switch. Ventilation can be performed. Also, there is no need for any installation work.
