JPH10141722A - Portable toilet ventilation device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To install a ventilation fan to a portable toilet even at a place where no commercial power supply is present and to perform a ventilation of air in the toilet. SOLUTION: A solar battery cell 2 is installed at the upper part of a portable toilet 1. A motor installed at a circle section of a ventilation fan 5 fixed to an outlet of a ventilation cylinder 4 is driven through a cable 3, a ventilation is sufficiently performed within the portable toilet so as to eliminate bad odor. As needed, it is also possible to mount a switch for turning ON, OFF an operation between the solar battery cell 2 and the ventilation fan 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a portable toilet that is temporarily used at a construction site or the like.

[0002]

2. Description of the Related Art Generally, ventilation of simple toilets is performed by natural ventilation, and ventilation is insufficient. The reason for this was that a toilet was needed when the power supply needed for forced ventilation was not provided nearby.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to sufficiently ventilate a toilet without a commercial power supply nearby, thereby eliminating an odor in the toilet.

[0004]

Means for Solving the Problems A forced ventilation motor is driven by utilizing the energy of a solar cell to positively ventilate a toilet.

[0005]

FIG. 1 is a simplified toilet (1).
The solar cell (2) is installed on the upper part of the car, and the motor inside the ventilation fan (5) attached to the outlet of the ventilation tube (4) is driven via the cable (3) to ventilate the simple toilet (1). And remove off-flavors. As a motor not shown, a motor that can be driven by DC is used, and has a simple structure that can directly connect the voltage of the solar cell. Further, in the nighttime when there is no sunlight, the work at the construction site is generally less, and the temperature in the toilet is reduced and the amount of off-odors is reduced as compared with the daytime. If the ventilation fan is attached at the outlet of the ventilation tube, it can be easily attached to a conventional simple toilet and is convenient. If necessary, a switch for turning on and off the operation can be provided between the solar cell (2) and the ventilation fan (5).

[0006]

According to the above-described contents, even in a place where there is no commercial power supply, forced ventilation of the simple toilet is performed, so that an unpleasant odor is eliminated, and there is an effect of providing a comfortable simple toilet. The effect of claim 2 has the effect of simplifying the structure and reducing the cost.
Claim 3 has the effect of simplifying the modification of a conventional simple toilet.
