Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a ceiling-embedded air conditioner.
[0002]
[Prior art]
Generally, a ceiling-type air conditioner body that includes a heat exchanger, a blower, a drain pump, and a box-shaped air conditioner body that contains a drain pan that covers the lower surface of the heat exchanger, and a decorative panel attached to the lower surface of the air conditioner body. A built-in air conditioner is known.
[0003]
This type includes a reinforcing member that extends from one side of the air conditioner body to the other side and supports the drain pan from below.
[0004]
[Problems to be solved by the invention]
By the way, in the conventional configuration, when the capacity of the air conditioner main body increases, the air conditioner main body is installed while keeping the installation width of the refrigerant pipe and the drain pipe constant for handling the refrigerant pipe and the drain pipe. The refrigerant pipe and the drain pipe connected to the heat exchanger have been enlarged in the direction of leading out. In this case, if the reinforcing member is spanned in a direction parallel to the direction of leading the refrigerant pipe connected to the heat exchanger and the drain pipe connected to the drain pump, the large-sized air conditioner body With this trend, a plurality of reinforcing members must be prepared in accordance with the shape of the air conditioner body, resulting in a problem that the cost of parts increases.
[0005]
Furthermore, conventionally, an electrical equipment box disposed between the drain pan and the decorative panel is provided, and this electrical equipment box has mounting brackets at both ends and is fixed to the reinforcing member so as to be sandwiched between two reinforcing members. .
[0006]
For this reason, mounting brackets connected to the reinforcing member must be provided at both ends of the electrical equipment box, resulting in a problem of increased component costs.
[0007]
Accordingly, an object of the present invention is to provide a ceiling-embedded air conditioner that can share a reinforcing member and reduce component costs even if the air conditioner main body is enlarged. .
[0008]
[Means for Solving the Problems]
The invention described in claim 1 includes a box-shaped air conditioner main body storing a heat exchanger, a blower, and a drain pan that covers the lower surface of the heat exchanger, and a decorative panel attached to the lower surface of the air conditioner main body. In the ceiling-embedded air conditioner, the reinforcing member of the air conditioner main body extends so as to be spanned in a direction orthogonal to the direction in which the refrigerant pipe and the drain pipe connected to the heat exchanger are led out. Mashimashi, the both end portions of the reinforcing member is screwed to the linked lifting lugs on the outside of the side plate of the air conditioner body, characterized in that it supports the drain pan from below.
[0009]
In the first aspect of the invention, since the reinforcing member is stretched in a direction orthogonal to the direction in which the refrigerant pipe and the drain pipe are led out, for example, the air conditioner body leads out the refrigerant pipe and the drain pipe. Even if the size is increased in the direction, the reinforcing member can be commonly used. For this reason, it is not necessary to prepare a plurality of types of reinforcing members in accordance with the size of the air conditioner body, and the component cost can be suppressed.
[0010]
The invention according to claim 2 includes a box-shaped air conditioner body that houses a heat exchanger, a blower, and a drain pan that covers the lower surface of the heat exchanger, and a decorative panel attached to the lower surface of the air conditioner body. In the ceiling-embedded air conditioner, when the capacity of the air conditioner main body increases, the air conditioner main body increases in size in a direction leading out the refrigerant pipe and the drain pipe connected to the heat exchanger, and the reinforcing member of the air conditioner main body lower but extends as stretched in the direction orthogonal to the extending direction, both end portions of the reinforcing member is screwed to hanger coupled to the outside of the side plate of the air conditioner body, the drain pan It is characterized by supporting from.
[0011]
In the invention according to claim 2, when the capacity of the air conditioner main body increases, the refrigerant pipe and the drain pipe connected to the heat exchanger are enlarged in the direction of leading out, while the reinforcing member is the refrigerant pipe and the drain pipe. Since the air conditioner main body is increased in size, the reinforcing member can be used in common. For this reason, it is not necessary to prepare a plurality of types of reinforcing members in accordance with the size of the air conditioner body, and the component cost can be suppressed.
