Benefits of technology

The present patent aims to solve the problem of complicated and expensive configurations in ceiling-embedded air conditioners by providing a simpler and improved performance configuration.

Problems solved by technology

As a result, the performance of the air conditioner may be affected.
However, the attachment of the separate component to the main plate as described above leads to a complicated configuration and an increase in the number of components and the number of manufacturing steps.
As a result, the manufacturing cost may increase.

Configuration of Ceiling-embedded Air Conditioner

[0017]Hereinafter, a ceiling-embedded air conditioner 100 according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 3. As illustrated in FIG. 1, the ceiling-embedded air conditioner 100 includes a casing 1, a motor 2, a main plate 3, a turbofan 4, a heat exchanger 5, and a bell mouth 6.

[0018]The casing 1 is embedded in a ceiling wall C of a building. The casing 1 has a rectangular shape when viewed from below, and is recessed upward to form a space therein. To be specific, the casing 1 includes a panel 1A exposed to the ceiling surface Ca and a box-shaped cabinet 1B provided above the panel 1A. The panel 1A includes a panel body 11, which is a rectangular frame body, and a grill 12, which is a suction port 11A provided at the center of the lower portion. The panel body 11 forms an outlet port 11B around the suction port 11A.

[0019]The motor 2 is provided at a central portion of a bottom su...

Abstract

A ceiling-embedded air conditioner includes, a casing, a motor including an output shaft protruding downward, the output shaft being driven to rotate about an axis, a main plate fixed to the output shaft and extending radially outward, a turbofan including an impeller, a heat exchanger passed through by air that is sent from the turbofan. And the main plate includes, a tapered portion, a recess formed to be recessed radially inward from the tapered portion, the recess being defined by a cylindrical plate portion extending along the axis, and a disk plate portion extending radially outward from the upper end of the cylindrical plate portion. And an opening is formed in the cylindrical plate portion, the opening penetrates the cylindrical plate portion in the radial direction, and configured such that a circulation flow that exits from the impeller and flows around above the main plate passes through the opening.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority to Japanese Patent Application Number 2020-015374 filed on Jan. 31, 2020. The entire contents of the above-identified application are hereby incorporated by reference.TECHNICAL FIELD[0002]The disclosure relates to a ceiling-embedded air conditioner.RELATED ART[0003]As an example of an air conditioner, a ceiling-embedded air conditioner is widely used. The ceiling-embedded air conditioner mainly includes a casing embedded in an indoor ceiling, a motor including an output shaft that rotates about an axis extending in a vertical direction, a turbofan, a main plate that fixes the turbofan to the output shaft, and a heat exchanger that surrounds the turbofan. By the rotation of the turbofan, indoor air is taken in from the central portion of the casing, and is supplied indoors as cold air or warm air by passing through the heat exchanger.[0004]As a specific example of such a ceiling-embedded air ...
