Description

Air conditioner with assembly structure for easy cleaning of blower fans and ducts {Air Conditioner with Assembly Structure for Easy Cleaning of Blower Fans and ducts}

The present invention relates to an air conditioner, and more specifically, to separate the grill assembly by physically separating the blower motor and blower fan from the grill assembly, while physically fixing it to the duct assembly and integrating it with the blower motor and blower fan duct assembly. It is easy to clean the blower fan and duct by exposing the blower motor and blower fan fixed to the duct assembly instead of running out of the grill assembly, making it easy and safe to separate the blower fan and duct for cleaning. This relates to an air conditioner having one assembly structure.

In general, an air conditioner is a device for comfortably adjusting indoor air conditions by performing a series of refrigerant cycles of compressing, condensing, expanding, and evaporating the refrigerant.

As an air conditioner, a separate type air conditioner is generally used in which a heat dissipating part with a condenser and a heat absorbing part with an evaporator are installed separately. At this time, the heat dissipating part is installed outdoors, so it is usually called an 'outdoor unit', and the heat absorbing part is installed in an air-conditioned space, that is, indoors, so it is called an 'indoor unit'.

Among conventional air conditioners, there are known types that have, for example, a circular front discharge port on the front of the indoor unit, as shown in Patent Document 1, and a side discharge port that is long and open in the vertical direction on the side.

In addition, as in Patent Document 2, forms having only circular front discharge ports, for example, on the front of the indoor unit are known.

However, in the conventional air conditioner including Patent Documents 1 and 2, the disassembly process for cleaning the blower fan and duct is inconvenient and complicated.

For example, the air conditioner of Patent Document 1 (see Figures 3 to 4 of Patent Document 1) is provided with a front discharge port on the front of the front cabinet to blow air to the front of the air conditioner and has a front blowing module inside. In order to blow air to the side of the air conditioner, a side discharge port and a side door module are provided between the front side of the rear upper cabinet and both sides of the front cabinet, and a side blowing module is provided inside.

In this air conditioner, a front blower guide and a side blower guide are installed from top to bottom inside the rear cabinet, and a front blower guide and a side blower guide are arranged in front of the rear cabinet from top to bottom. The front blower guide has a front blower guide and a side blower guide. It has a structure in which a fan and a front blowing motor are installed, while a side blowing fan and a side blowing motor are mounted on the side blowing guide.

Additionally, the front blowing module further includes a front blowing fan housing that forms the rear wall of the air flow duct. Likewise, the side blowing air module further includes a side blowing fan housing forming the rear wall of the air flow duct. The front wall of the air flow duct is formed by the discharge guides of the front door module and the side air blowing module, respectively.

In this air conditioner, the front blower fan, front blower motor, and side blower fan and side blower motor are not mounted (assembled) on the blower fan housing located at the rear, but rather have a front door module located at the front of the blower fan housing. and is mounted on the side discharge guide. Each blower motor is assembled in front of the front door module and the side discharge guide, and each blower fan is assembled on the output shaft of the blower motor that protrudes through the rear of the front door module and the side discharge guide.

If you remove the front cabinet, side door, front door module, and side discharge guide from the front of the air conditioner in order to clean (or wash) the blower fan and motor, each blower fan and motor will be connected to the front door module. and is separated while being integrally attached to the side discharge guide.

For this reason, place the separated front door module and side discharge guide on the floor, point the blower fan toward the sky, separate the blower fan from the output shaft of the blower motor, and turn the front door module and side discharge guide over again to start the blower motor. Since it has to be separated, the separation process for cleaning is inconvenient and cumbersome.

In addition, when the front door module and the side discharge guide are separated, the blower fan and blower motor come out, so the wiring harness that supplies power to the blower motor is pulled during the process of setting it down on the floor, causing a risk of disconnection. If this occurs or the length of the wire is short, it may be difficult to place the front door module and side discharge guide on the floor.

Additionally, since the blower fan cannot be cleaned unless the front door module and side discharge guide are removed, the above complicated work must be performed every time.

In addition, even during reassembly, when the wire bundle is seated, there is a possibility that the wires become caught in the gap between parts, which can easily cause disconnection or peeling of the covering, which can cause electrical hazards.

Meanwhile, Patent Document 2 discloses an air conditioner in which the front of the air conditioner is composed of a discharge plate, and three openings are formed in the discharge plate to discharge air.

This type of air conditioner also has a duct arranged at the rear, and the fan driving unit (motor) and blowing fan are mounted on the flow path forming frame in front of the duct.

Therefore, when the front flow path forming frame is separated, the motor and blower fan come out together, so in order to clean the motor and blower fan, it is necessary to separate the flow path forming frame, turn it over, and place it on the floor. As with the air conditioner in Document 1, the process for separation and cleaning is complicated, and there is still a risk that the problem of pulling the wire bundle may occur.

On the other hand, in other conventional air conditioners, even if the motor and blower fan are separated, the duct part is placed on the opposite side of the side where the motor and blower fan are installed, making it difficult to clean the duct, which requires complicated separation of the duct. shall.

As above, in the air conditioners disclosed in the past, including Patent Documents 1 and 2, the separation work for cleaning the blower fan and motor is complicated and cumbersome, and various risks exist.
