Abstract

PURPOSE:To sweep heavy air, containing moisture and the like in a room, away surely and realize high ventilating effect, by a method wherein a plurality of air blow-off ports, generating whirling current of air about the center of the room respectively, is provided on a plurality of ventilating tubes provided on the inner surface of the walls of the room. CONSTITUTION:Respective ventilating tubes 2 are provided with a multitude of air blow-off ports 21,... with a given intervals in up-and-down and horizontal jet streams of air toward the center of a toilet, for example, are generated from respective ventilating tubes 2 by fans 5, provided at the upper end thereof respectively. In this case, the jet streams of air from respective ventilating tubes 2 are provided with given directions deviated slightly from the center of the toilet whereby the whirling stream of air is generated about the center of the toilet. Accordingly, this whirling stream is elevated while whirling by the help of elevating force generated by the suction effect of a suction duct 3 whereby air in the whole area of the toilet is rolled into the stream of this vortex and the air, containing bad smell, moisture and the like, may be discharged forcibly and efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a ventilation system for strongly ventilating toilets, cots, hospital rooms, etc.

(Prior art) Conventionally, the ventilation of toilets, etc., where foul odors, moisture, and house dust are likely to be trapped, has been carried out by natural ventilation or strong T111 ventilation using a ventilation fan. Since the air is sucked out only from one point, the air tends to stagnate, making it impossible to achieve a sufficient ventilation effect.

(Objective of the Invention) Therefore, the present invention provides a ventilation device that can forcefully exhaust indoor air by drawing it into an air flow toward an exhaust port, and can achieve a high ventilation effect.

(Structure of the Invention) The present invention includes a plurality of blower pipes installed on the inner surface of a room wall, a blower generating means for sending air to each of the blower pipes, and an exhaust port provided on the room wall, Each blower pipe is provided with a plurality of air outlets that blow air in a direction offset from the center of the room to generate a swirling flow of air around the center of the room.

In this way, by creating a swirling flow of air around the center of the room by the blowing action from around the room, the indoor air can be drawn into this swirling flow and forced to move toward the exhaust port. , even heavy air containing moisture can be reliably swept away to achieve a high ventilation effect.

(Example) Embodiments of the present invention will be described with reference to the drawings.

In this embodiment, a toilet is used as an example of ventilation, but the present invention can be widely applied to other relatively small rooms that require ventilation, such as bed cabins and hospital rooms.

In FIG. 1, reference numeral 1 is a toilet, and each of the four corners of the toilet 1 is provided with air pipes 2 in the vertical direction, and an exhaust port (not shown) is provided in the center of the ceiling wall.
A suction duct 3 communicating with the outside is connected to this exhaust port. This suction duct 3 is provided with a suction fan (not shown), and the suction force of this suction fan gives upward force to the air in the toilet. Note that 4 is a toilet unit.

As shown in FIG. 2, each blower pipe 2 is provided with a large number of air outlets 21 at regular intervals above and below, and
A blower 5 serving as a blower generating means for sending air into the blower pipe 2 is provided at the upper end of each blower 5.
Due to the simultaneous blast from the air outlet 21 due to the blowing action, a sideways air jet is generated from each blast pipe 2 toward the inside of the toilet. in this case,
As shown in Fig. 3, the direction of the air jet a from each Jl pipe 2... is a direction offset from the toilet center 0, that is, a tangential direction to an imaginary circle drawn at the center of the toilet. As shown, the air outlet 21 of each air pipe 2...
・The direction is determined. In this way, 8th delivery Jl! ! 2
It is constructed so that a swirling flow of air is generated around the toilet center O by the air jet from...

In such a configuration, after or during use of the toilet, the suction fan of the suction duct 3 and each blower 5...
When the is driven, the rotating FILb around the toilet center O generated by the air jet a from each of the air blowers 9, 2, etc. as described above is subjected to a rising force due to the suction action of the suction duct 3 described above. This creates a so-called tornado flow that swirls and rises toward the exhaust port, and the air in the entire area of the toilet is caught up in this tornado flow and rises in a spiral shape toward the exhaust port. In this way, air containing foul odors, moisture, etc. inside the toilet can be forcibly and efficiently discharged.

Although it is most desirable to provide the exhaust port on the ceiling wall of the room as in the previous embodiment, it may also be provided on the side wall or floor wall. If installed on a floor wall, a tornado flow will occur downward. In addition, in order to generate a strong tornado flow, it is desirable to provide a suction fan in the suction duct 3 as in the above embodiment, but even if this suction fan is not provided, the outside will have a negative impact relative to the inside of the toilet. Since the suction force acts on the swirling flow, there is no problem in generating a tornado flow. Further, depending on the positional conditions between the room to be ventilated and the outside, the suction duct 3 may not be provided and the exhaust port may be opened directly to the outside.

On the other hand, in the above embodiment, each of the blower pipes 2... was provided at the corner of the room. It may be provided on both sides. In addition, in the above embodiment, an air blower 115 was provided for each air pipe 2..., but each air pipe 2... was connected to each other with a vibrator, and air was blown to all air pipes 2... with a - stand blower. It may be configured to do so.

(Effects of the Invention) As described above, according to the present invention, a plurality of blower pipes each having a plurality of air outlets are provided on the inner surface of the room wall, and air is distributed around the center of the room by air jets from the respective blower pipes. The structure is designed to generate a swirling flow, draw indoor air into a tornado flow based on this swirling flow, and exhaust it from the exhaust port, which greatly improves ventilation efficiency compared to the conventional air suction method using only a ventilation fan. Moreover, it can reliably exhaust air containing odor, moisture, house dust, etc. from toilets, pet houses, hospital rooms, etc., thereby keeping the rooms clean.
