Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a bench with an air conditioner for simultaneously forming a local space (zone) and air conditioning in the zone.

[Prior Art] FIG. 8 shows a perspective view of a conventional bench used in a bus stop or the like.

In such a bench 100, enclosures 101 are provided on the ceiling, both sides, and the back side to prevent direct sunlight and wind.

[Problems to be solved by the device]

The conventional bench having the above-mentioned enclosure has the following problems to be solved.

That is, since the ceiling and the like are attached in order to avoid direct sunlight, there is a problem that the ventilation is poor in the summer and it becomes hot.

Even if you try to cool this inside as a countermeasure, the conventional air conditioner targets closed space, so you can not air-condition the inside of the bench (in the enclosure) to every corner, and cold air leaks out of the bench. The cooling feeling was obtained only when the cold air directly hits the human body.

Moreover, in winter, although the north wind can be avoided by the enclosure, the air conditioning (heating) inside this bench did not result in satisfactory air conditioning because the hot air leaked to the outside as in the case of cooling.

As a means for not letting the conditioned air escape to the outside, there is a measure such as hanging a vinyl sheet at the entrance of the bench, but it is inconvenient for people to come and go.

[Means for Solving the Problems]

The present invention provides the following (1), as means for solving the above problems.
It is intended to provide the bench with an air conditioner according to (2).

(1) In a bench provided with enclosures on the ceiling, both sides and the back side, jet generating means provided so as to be able to blow an air flow downward from the edge of the ceiling, and air blown by the jet generating means A bench with an air conditioner, comprising an air conditioning unit for air conditioning the inside of a zone of the space formed by the flow and the enclosure.

(2) In the bench with an air conditioner according to (1) above, an air conditioning unit is installed inside the bench.

[Action]

Since the present invention is configured as described above, the following (1),
It has the function of (2).

(1) In the description in (1) above, since the air flow can be blown downward from the edge of the ceiling of the bench enclosure by the jet flow generating means, the enclosure and the blown air flow The formed zone is independent of the atmosphere,
It can be an air-conditioned closed space. Therefore, if the zone is air-conditioned by a separate air-conditioning unit, the entire bench will be air-conditioned.

(2) In the configuration of (2) above, the air conditioning unit in the configuration of (1) above is provided inside the bench, so that cold and warm air is suitable for people sitting on the bench, for example, for heating. In order to heat the head cold feet, warm air can be blown to the feet, sucked in the vicinity of the head, and vice versa for cooling.

〔Example〕

The first to fourth embodiments of the present invention will be described with reference to FIGS. In addition, in order to avoid redundancy in each of the embodiments, the same components as those in the conventional example or the previous examples are designated by the same reference numerals, and the description thereof will be omitted. Regarding the operation and the like, the description of the same operation as that of the previous embodiment will be omitted, and only the operation unique to the embodiment will be described unless particularly necessary.

First, the first embodiment will be described with reference to FIGS. 1 and 2.
FIG. 1 is a perspective view of this embodiment, and FIG. 2 is a side sectional view of an essential part of FIG.

In both figures, the jet flow generating means 3 is composed of a guide 1 surrounding the fan 2, and is attached substantially horizontally inside the upper end of a box body 4 that covers the ceiling, side, and back of the bench 7, and the fixed wall 13
It is installed so that it can blow out air. The fluid treatment device 12 includes a heat exchanger 10 and a fluid pressure feeding means 9, and is provided inside the bench 7. Reference numeral 14 denotes an outdoor unit, which integrally incorporates a heat exchanger, a compressor, and fluid pressure feeding means, is connected to the fluid processing device 12 by a pipe 15, and integrally forms a closed circulation path for the cooling medium. When forming an air conditioning unit.

Next, the operation of the above configuration will be described.

The fluid (air) around the fluid treatment device 12 is sucked from the suction port 11 by the fluid pressure feeding means 9, moves to the heat exchanger 10 and the discharge port 8, and is blown out from the discharge port 8.

If a dust filter, a deodorizing filter or the like is provided on the upstream side of the heat exchanger 10, it is possible to remove dust and deodorize at the same time in addition to cooling and heating the fluid (air).

For example, when activated in the cooling condition, the jet flow generating means 3 is also activated at the same time, and the fluid (air) in the space 5 is sucked by the jet flow generating means 3 as the suction flow A and blown out as the jet flow B.
Along the end of the box 4 flows almost directly under the fixed wall 13
Forming a layered flow of air curtains towards.

On the other hand, the fluid treatment device 12 placed on the fixed wall 13 sucks the fluid 6 inside the jet flow B, that is, the inside of the box body 4 as the suction flow a, discharges it as the discharge flow b, and recycles it as the circulation flow c. Since it circulates, it does not hinder the zone formation by the jet B.

In this way, the space with the bench 7 and the space 5 can be partitioned by the jet B, and it becomes possible to air-condition only the space with the bench 7 of the box body 4, and cold air leaks from the space of the bench 7 to the outside. There is no energy saving.

A person can freely enter and leave the bench 7 because of the partition by the jet B, which does not hinder the forward field of view.

Next, a second embodiment of the present invention will be described with reference to FIG.

In the figure, the suction flow a of the fluid treatment device 12 is sucked in from above and discharged as a discharge flow b from below to form a circulation flow c.

That is, it is configured such that the blowing and the suction during heating can be selectively reversed from those during cooling. Other configurations are similar to those of the first embodiment. Normally, warm air is likely to be trapped in the upper part of the box body 4 due to thermal buoyancy, but according to this embodiment, warm air is blown out from the feet, and ideal air conditioning for head cold foot heat can be obtained.

Next, a third embodiment of the present invention will be described with reference to FIGS.

In both figures, the jet flow generating means 3a is provided on the top of the roof of the box body 4a, and the front end and the rear end of the roof are connected by a duct,
The suction flow A is sucked in at the rear end and blown out as a jet flow B from the front end. Other configurations are similar to those of the first embodiment. According to this embodiment, there is an advantage that rain or the like does not enter the box body 4 from the roof.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. 6 and 7.

In both figures, two sets of box bodies 4b are provided symmetrically in a pair with back to back, jet generating means 3b is also provided on each roof, and bench 7 and other equipment are also provided symmetrically. .

This embodiment is not only suitable for places where bus stops are provided in multiple rows, such as plazas and terminals, but the leeward zone is normal even when it is difficult to form a normal air curtain on the windward side due to strong wind, for example. The advantage is that the air conditioning is maintained.

As described above, according to the first to fourth embodiments, the jet flow generating means forms the zone partitioned from the outside air around the bench having the enclosure, and the inside can be air-conditioned by the fluid treatment device. There is an advantage that people can get in and out freely and a comfortable bus stop bench can be obtained.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

(1) Since the air-conditioning zone is formed around the bench by the jet flow blown downward from the end of the ceiling, the bench can be air-conditioned without wasting heat energy.

(2) Since the partition between the bench and the outside is done by fluid (air), people can freely enter and exit and the view is not obstructed.

(3) When an air conditioning unit is provided in the bench, it is possible to perform appropriate air conditioning that copes with the heat of people's head and feet.
