Multi-Drop Diffusion Fan Assembly for Ceiling Cassette Air Conditioner Attachment

The present invention relates to a multi-diffusion fan assembly for attaching a ceiling cassette air conditioner,

More specifically, the airflow discharge range of the conventional ceiling cassette air conditioner indoor unit, which is installed on the ceiling of the building interior and is provided with four blowout ports formed at the center of the front of the suction grille in four directions to surround the intake port, is used for cooling or heating. In order to overcome the limitations of the conventional ceiling cassette air conditioner indoor unit airflow discharge structure, which cannot be evenly distributed and has low heating efficiency,

It can be attached as it is without changing the structure of the ceiling cassette air conditioner indoor unit, and it receives the discharge airflow discharged from the air conditioner air outlet and drives it with no power, and introduces the discharge air in the direction of the hub to generate a radial outward air flow. In forming a multi-diffusion fan for attaching a ceiling cassette air conditioner indoor unit to induce diffusion to spread widely indoors,

Diffusion fan is an asymmetrical spatula shape, a rotor blade formed directionally by speaking and gathering like a round frame with unit rotation blades formed with wings of a plurality of leaves having a hydrodynamic shape so that the wind can be split into pieces. By providing a multi-discharge discharge airflow diffusion fan that is eco-friendly and hydrodynamic in shape,

Similar to the natural wind, it spreads and spreads the air more softly and richly than the existing air-conditioning wind into the room, and allows users in different directions to continuously blow the wind at the same time to maximize the blowing efficiency and reduce the energy consumption. The present invention relates to a multi-diffusion fan assembly for attaching a ceiling cassette air conditioner that spreads to a wide range around a ceiling air conditioner indoor unit as a fan and provides a natural decorative effect of visually beautiful leaves as well as a blowing function for creating a comfortable indoor environment of the occupants.

Almost all buildings, such as large buildings and homes, are equipped with air conditioners for air conditioning and cooling.

The air conditioner is an abbreviation of air conditioner, which is a ceiling type installed on the indoor ceiling so that the front surface is exposed, a stand type package type, a wall hanging type installed on the indoor wall, and a part of the air conditioner is mounted on the wall and the ceiling. There is a ceiling cassette type that is embedded and installed,

It is divided into a separate air conditioner composed of an indoor unit equipped with an evaporator and a blower fan, an outdoor unit provided with a compressor, a condenser, and an expansion valve, and an integrated air conditioner that is not separately formed.

The ceiling cassette type air conditioner indoor unit, which can be attached to the ceiling among the air conditioners, is installed on the indoor ceiling, and the indoor air suction grille is formed in the center of the bottom of the housing, and the airflow outlets are formed on four sides of the front, rear, left, and right sides of the indoor unit. It is a blower structure that sucks indoor air from the suction grill of the central part and discharges heat exchanged air in the four sides, thereby cooling and heating the room by discharging the air or cooling and heating it.

However, because the ceiling cassette type air conditioner is installed on the ceiling, the space utilization is good and the airflow for cooling or heating is discharged obliquely downward in four directions, so that the airflow is not spread far, despite the various advantages such as airflow. The ventilation range is limited, creating a cooling and heating blind spot, and the direct contact with cold winds causes discomfort and causes cooling sickness, which is harmful to health.The lower and lower temperatures occur during cooling. In buildings that are difficult to hold and have a ceiling height of more than 3.0 m, there is a problem that energy efficiency is inferior, such as a large heat loss and a large difference in temperature between the upper and lower sides, resulting in a long preheating time.

In addition, as a prior art for solving the above problems, Korean Patent Office Publication No. 10-2007-0072886 (July 06, 2007) "airflow diffusion device" is an airflow diffusion device installed in the ceiling-mounted air conditioner, air conditioning Although the impeller rotates and the blade member rotates by the wind blower discharge wind of the air in turn, the air is discharged from the air conditioner to the entire air-conditioning space to solve a certain amount of room temperature deviation. It is difficult to manufacture or dismantle due to a lot of loss and complicated structure, and there is a limit to increase the diffusion performance of the discharge airflow, and there is a problem in that it is not possible to obtain a different decorative effect that changes the atmosphere of the interior space with a plain wing configuration.

Therefore, the present inventors focus on the above-mentioned viewpoint, and the airflow diffusivity, safety and durability, aesthetics, and work productivity are greatly improved compared to the prior art, and are similar to natural wind, and diffuse and supply a wider range of soft and abundant wind into the room. We develop a multi-diffusion fan assembly for ceiling cassette air conditioner that can effectively meet various applications as a diffusion fan by allowing users in the direction to continuously blow at the same time, maximizing blowing efficiency and reducing energy consumption. As a result, the present invention has been completed.

As described above, the air diffusion diffuser of the prior art has various problems.

In order to overcome the limitations of the ceiling cassette air conditioner indoor unit air discharge structure, which has a narrow airflow discharge range of the conventional ceiling cassette air conditioner indoor unit can not evenly distribute the heat or heat to the cooling and heating efficiency,

In forming a multi-diffusion fan for attaching to a ceiling cassette air conditioner indoor unit which receives discharge airflow and drives with no force and draws discharge air in the direction of the hub to generate a radial outward airflow, and induces the airflow to spread widely throughout the room.

Airflow diffusion fan for ceiling cassette air conditioner indoor unit that maximizes blowing efficiency and reduces energy consumption by supplying a wider range of softer and richer winds than indoor air conditioners and allowing users in different directions to continuously blow wind simultaneously. To solve the technical problem to be developed in the present invention.

As described above, the present invention has been made to solve the above-mentioned problems of the prior art,

It can be attached as it is without changing the structure of the ceiling cassette air conditioner indoor unit, and it receives the discharge airflow discharged from the air conditioner air outlet and drives it with no power, and introduces the discharge air in the direction of the hub to generate a radial outward air flow, but discharges the airflow indoors. To form a multi-diffusion fan for attaching the ceiling cassette air conditioner indoor unit to induce diffusion to spread widely,

A simple rotating body with a plurality of blades arranged symmetrically, uniformly and radially, and not as a diffusion fan,

Diffusion fan is a streamlined asymmetrical wide spatula shape that makes the air flow more smoothly, and the unit rotation wing shaped in the shape of a large leaf spread in one direction has a hydrodynamic shape so that the wind can be split into pieces. In order to uniformly generate the diffusion airflow, the two or more unit rotor blades are connected to each other like a round frame in a state where they are spaced apart from each other by a round frame, and are formed in a direction of the rotor blades which are naturally oriented and have a hydrodynamic shape. As a discharge airflow diffusion fan, it turns in a direction of rotation in one direction of the circumference to form a swirl flow with the centrifugal force of a circular trajectory formed by the rotation of a rotary blade formed to have a directivity to give a greater centrifugal force to the air conditioner airflow. Discharge from air conditioner in wide direction It is an object of the present invention to provide a multi-diffusion fan assembly for attaching a ceiling cassette air conditioner, which can diffuse winds and additionally implement an afterimage effect of a natural leaf image in which the leaf shape changes in the circumferential direction as the leaves fly as the wind blows.

In addition, the present invention is a multi-diffusion fan assembly for attaching a ceiling cassette air conditioner that can spread the wind discharged from the air conditioner,

The wide leaf-shaped unit rotating blades constituting the diffusion fan and spread in one direction further form an inclined angle airflow diffusion vane having an inclination angle as an auxiliary wing at the end of the unit rotating blade to form an additional air diffusion flow. In addition to providing greater centrifugal force and rotating blades of a certain area, the larger radius of rotation increases the range of the outward blowing direction in addition to the front direction, allowing the air-conditioning airflow to be spread widely. Another object is to provide a multi-diffusion fan assembly for attaching a ceiling cassette air conditioner.

The multi-diffusion fan assembly for attaching the ceiling cassette air conditioner of the present invention as described above,

Similar to the natural wind, it can supply softer and richer wind than the existing air-conditioning wind, and economic expansion of the airflow discharge range enables the users in various directions to continuously and simultaneously spread the indoor air in a wide range of appropriate and uniform winds. It can blow the wind to maximize the blowing efficiency and reduce the energy consumption, so it spreads to the wide area around the indoor air conditioner indoor unit as the original airflow fan, and the blowing function to create a comfortable indoor environment for the occupants. The function that adds the afterimage effect of the natural leaf image that changes the shape of the leaf in the circumferential direction when it rotates like a flying leaf, and gives the natural decorative effect of the colorful and beautiful leaves that change the atmosphere of the indoor space. It can implement a complex synergistic effect of Formative.

In particular, the present invention is a simple rotating body having a plurality of blades arranged symmetrically, uniformly and radially, without deterioration of the airflow efficiency even if the course of the air flow is diffused and deviates from the axis, and is not a diffusion fan,

A streamlined, asymmetric, wide spatula shape that facilitates the flow of air, and unitary rotor blades shaped into a plurality of unidirectional wide leaf shapes with a hydrodynamic shape to send the wind into small pieces to uniformly spread the airflow in the circumferential direction. In order to generate a plurality of two or more in a state separated from each other at a predetermined angle is connected to form a round rim and are formed in a directional direction to rotate the shape of the rotary wing of the structure specialized in diffusing air radially,

By adding the numbers in a combination effect in the same direction as combining a plurality of leaf-shaped rotating blades helically oriented in a spiral direction and twisting the directions little by little, the rotating blades act as an array, and thus, a wide direction at a wide direction. As a result, it is possible to uniformly spread the air conditioning discharge wind, and thus, it is possible to prevent the temperature difference from occurring according to the location of the room, thereby reducing the discomfort felt by a large number of users and providing a comfortable indoor environment.
