[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ceiling-mounted air conditioner.

[0002]

[Prior art]

 In recent years, comfort of ceiling-mounted air conditioners has been demanded, and technology for improving air conditioning performance has become important. Related to the above technique, there is a conventional peripheral device for the outlet of a ceiling-mounted air conditioner disclosed in Japanese Patent Laid-Open No. 63-254345. Hereinafter, the conventional ceiling-mounted air conditioner will be described with reference to the drawings.

FIG. 2 is a partial vertical cross-sectional view of an indoor unit of a conventional ceiling-mounted air conditioner. FIG. 3 is a perspective view of an indoor unit of a conventional ceiling-mounted air conditioner.

FIG. 4 is a vertical cross-sectional view taken along line X-X ′ of FIG. 2 to 4, 11 is a ceiling-mounted air conditioner indoor unit main body installed on the ceiling, 12 is a rectangular decorative panel attached below the indoor unit main body 11, 13 is a ceiling-mounted air conditioner indoor unit main body 11 A suction port located at the lower side and in the center, 14 is an outer peripheral portion of the decorative panel 12, and 15 is a discharge port provided so as to surround four sides of the suction port of the ceiling-mounted air conditioner indoor unit body 11.

In FIG. 4, 16 is a partition in the middle of the inlet 13 and the outlet 15, 20 is a fan provided in the center of the indoor unit body 11, 21 is a fan motor for rotating the fan 20, Reference numeral 22 is a pair of heat exchangers provided so as to surround the fan 20 from the side, 23 is a drain pan provided under the heat exchanger 22 which is formed in an annular shape, and 17 is a blower for the air that has exchanged heat with the heat exchanger 22. It is an air guide portion leading to the mouth 15.

The operation of the ceiling-mounted air conditioner configured as above will be described below. When the fan 20 rotates, the indoor air is sucked into the ceiling-mounted air conditioner indoor unit main body 11 through the suction port 13 and reaches the heat exchanger 22. The heat-exchanged air is blown into the room through the outlet 15.

[Problems to be solved by the device]

 However, the conventional ceiling-mounted air conditioner described above has a shape different from that of the ceiling-mounted air conditioner 15 due to the expansion of the inlet 13 of the ceiling-mounted air conditioner accompanying the increase in the amount of intake air required to increase the amount of blown air. The air intake from the outlet 15 of the ceiling-mounted air conditioner is close to each other and the short-circuit phenomenon is likely to occur when the airflow from the outlet 15 of the ceiling-mounted air conditioner is sucked into the inlet 13 of the air conditioner. As a result, the cooling and heating capacity of the ceiling-mounted air conditioner declines, and the comfort of the air-conditioned space cannot be obtained.

In order to solve the above problems, the present invention solves the problems of the conventional ceiling-mounted air conditioners, and aims to improve the air-conditioning space comfort by improving the heating and cooling capacity by preventing a short circuit.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the ceiling-mounted air conditioner according to the present invention has a structure in which a convex portion projecting downward is provided between the suction port and the discharge port so as to be integrated.

[0010]

[Action]

 Since the ceiling-mounted air conditioner of the present invention is provided with the convex portion, the air blown out from the outlet can be prevented from flowing into the suction side, so that the short circuit does not occur.

[0011]

【Example】

 An embodiment of a ceiling-mounted air conditioner according to the present invention will be described below with reference to the drawings. It should be noted that the same components as those of the related art are designated by the same reference numerals and detailed description thereof will be omitted.

FIG. 1 is a partial vertical sectional view of an indoor unit of a ceiling-mounted air conditioner according to the present invention. In FIG. 1, reference numeral 2 is a quadrangular panel attached below the indoor unit body, and is a decorative panel having a curved surface B with a chamfered portion facing the outlet 5. 3 is a ceiling installation type air conditioner indoor unit main body, 4 is a peripheral part of the decorative panel 2, 5 is a ceiling installation type air conditioner indoor unit main body outlet, 6 is a partition between the intake 3 and the outlet 5. , 7 are air guides for leading out the heat-exchanged air to the outlet 5.

Reference numeral 8 is a convex portion that is attached to the lower part of the partition 6 in the middle of the suction port 3 and the discharge port 5 to be integrated with each other to increase the distance between the suction port 3 and the discharge port 5.

The operation of the ceiling-mounted air conditioner configured as above will be described below. The room air is sucked into the ceiling-mounted air conditioner indoor unit body 1 through the suction port 3, heat-exchanged, and blown into the room through the blowing port 5.

At this time, since the gap between the intake port 3 and the outlet port 5 is lengthened downward, the air blown out from the outlet port 5 can flow along the partition 6 extending downward. Therefore, the air flow W1 blown out from the outlet 5 can be extended downward as compared with the conventional one, and a short circuit does not occur.

[0016]

[Effect of device]

 As described above, since the ceiling-mounted air conditioner of the present invention has the convex portion projecting downward between the inlet and the outlet, the air blown from the outlet is made to flow along the partition extending downward. be able to. Therefore, the airflow blown from the outlet can be extended downward as compared with the conventional one, so that a short circuit can be prevented, the cooling and heating capacity can be improved, and the comfort of the air-conditioned space can be improved.
