Description

INDUSTRIAL AIR CONDITIONER WITH MULTIPLE JET BLOWERS ROTATABLE INDEPENDENTLY}

The present invention relates to an industrial air conditioner, and more particularly, when the user partially occupies a large indoor space such as a factory, a gymnasium, or an auditorium, it is possible to spray air-conditioned air by a heater or a heat exchanger to various points at the same time. An industrial air conditioner having a plurality of jet injectors capable of independent rotation.

Conventionally, in cooling or heating a large indoor space such as a factory, a gymnasium, or an auditorium, an air conditioner is installed, and the air conditioner in the air conditioner is guided to a point where cooling or heating is required through a duct and sprayed. In the air conditioner, a long distance injector or jet fan in the form of a nozzle is installed in the air conditioner to inject air over a long distance to a point where direct cooling or heating is required. Air-conditioned air is formed by a high speed fan, and focused and directed by a remote injector or a jet fan, which is injected to a long distance. Long-distance spraying is preferred in recent years because it saves the cost of installing a separate duct and enables direct spraying to local points.

A typical long-range air conditioner is disclosed in Korean Utility Model Publication No. 20-0181348. Patent No. 20-0181348 aims to not only generate jet airflow by installing a jet fan, but also to change the jet direction of the jet fan, but its improvement is required due to the following structural disadvantages.

First, the jet fan according to the design of 20-0181348 has a disadvantage in that it can not inject air to several points at the same time. 20-0181348 devised to rotate the jet fan in the vertical, left, and right directions, the outer fan frame rotatably coupled to the air conditioner body frame, the inner fan frame rotatably coupled to the outer fan frame, the inner It is configured by fixing at least one jet fan to a support plate fixed to the fan frame. At this time, the fixing plate for installation is coupled to the middle part of the fan body of the jet fan, and the middle part of the jet fan is inserted into the circular coupling hole formed in the support plate fixed to the inner fan frame, so that the edge of the coupling hole and the fixing plate of the jet fan body are bolted. Is fastened to. Therefore, according to the design of 20-0181348, the jet fan itself is completely fixed to the inner fan frame so that it cannot move, and the inner fan frame or the outer fan frame must be rotated to rotate the jet fan. However, when the fan frame is rotated instead of the jet fan itself, when the left and right rotations are made, the gap between the outer fan frame and the main frame is increased, whereby outside air flows into the space and air-conditioned air leaks into this gap. In the vertical rotation, the gap between the inner fan frame and the outer fan frame is widened so that outside air flows into this gap and air-conditioned air leaks. This can be clearly seen with reference to FIGS. 7 and 8 of the present invention. This is a problem that occurs when the left and right sides of the outer fan frame or the upper and lower sides of the inner fan frame protrude too far in the up, down, left and right directions. Therefore, the air conditioner according to the design of 20-0181348 has no choice but to limit the amount of rotation of the jet fan to a small angle.

Next, the jet fan according to the design of 20-0181348 has to install a plurality of jet fans inside the inner fan frame, and turn the entire fan fan by turning the inner fan frame or the outer fan frame, so if the size of the jet fan is large ( In general, a large auditorium is 5m in length and 1.5m in diameter), even when using a large torque, it is very difficult to rotate up and down and left and right, and the motor is frequently burned out due to a large load.

Next, the jet fan according to the design of No. 20-0181348 is fixed inside the fan frame so that all jet fans face a certain direction even when a plurality of jet fans are attached. If people are dispersed, there is a disadvantage that can not directionally spray the air conditioning at the same time. This is due to the structure in which the jet fans are all fixed in the inner fan frame in a predetermined direction and the inner fan frame or the outer fan frame is rotated when the jet fan is changed in direction.

The present invention solves the problems of the above-described conventional industrial air conditioner with a jet fan and can be independently rotated even with a plurality of jet injectors to provide an industrial air conditioner with a smooth rotation of the jet injector have.

Another object of the present invention is a plurality of independent rotation that can be rotated so that when people are dispersed in two or more points of the air conditioner installation place, such as factories, auditoriums, gymnasiums, each point is divided into each point to directionally spray the air An industrial air conditioner having a jet injector is provided.

The present invention to achieve the above object is provided with an air injector chamber on the air conditioning chamber, the industrial having a jet injector for remotely injecting the air introduced into the air injection chamber (B) in a predetermined direction by a jet injector module In the air conditioner, the jet injector module is a rectangular frame installed in the front of the air injection chamber, by a modulus motor coupled to the vertical installation rotary shaft at regular intervals inside the frame and connected to one end of the vertical installation rotary shaft A square rotating cell which is driven and rotates in the left and right direction inside the frame, and is driven by a modulus motor which is coupled to the inside of the rotating cell one by one horizontally installed rotating shaft and connected to one end of the horizontally installed rotating shaft, thereby being moved up and down inside the cell. A jet injector rotating in a direction; It is characterized in that it comprises a; and shielding all around the jet injector of the frame, the expansion and contraction module for providing elasticity so that the jet injector can be freely rotated up and down and left and right independently.

According to the present invention having the above-described configuration, it is possible to rotate independently even with a plurality of jet injector is very smooth rotation of the jet injector, easy to change the direction even when the jet injector is large, factory, auditorium, gymnasium If people are dispersed in two or more points of the air conditioner installation place, the air conditioner can be divided into each point and spray the air conditioned at the same time.
