Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a frame structure of a ceiling-embedded fan coil unit.

Conventional configuration and problems thereof Conventionally, a ceiling-embedded fan coil unit has a configuration as shown in FIGS. 1 and 2.

That is, a heat exchanger 1 that performs air conditioning and heating by passing cold and hot water has a side plate 2, an upper cover 3 on the top side,
Further, it has a lower cover 4 on the lower side, and further has an air outlet cover 5 having an air outlet 5a on the front part. A dew pan 6 is attached to the lower part of the lower cover 4 with a metal fitting 6a, and a hole 4 provided in the lower cover 4
Dew is guided to this dew receiving tray 6 from a. Note that 7 in the figure is a motor mounting plate that fixes the blower 8.

Conventionally, the ceiling-embedded fan coil unit 10 is embedded in the ceiling or a descending ceiling, and the air outlet 5a and the opening in the ceiling are connected by a duct to perform heating and cooling.

However, although this configuration is a fan coil unit consisting only of the heat exchanger 1 and the blower 8, it has the disadvantage that the number of parts is large, and the larger the unit, the heavier the unit and the higher the cost.

Purpose of the invention The present invention solves the above-mentioned conventional drawbacks, and aims to provide a ceiling-embedded fan coil unit that is simple in structure, lightweight, and inexpensive.

Structure of the Invention In order to achieve the above object, the present invention provides a side plate of a heat exchanger with a protruding piece constituting the side piece of the outlet, an upper cover with an upper protruding piece constituting the upper piece of the outlet, and a lower protruding piece. A lower protruding piece constituting a lower piece of the air outlet is provided on the cover, a mounting plate to which a blower is fixed is provided on the side opposite to the duct connection side of the heat exchanger, and the air outlet is connected to the duct by each of the protruding pieces. It is designed to compose the following.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 3 and 4. In the figure, 13 is a main body of a ceiling-embedded fan coil unit, which is equipped with a heat exchanger 14 through which hot and cold water flows. The side plates 15 and 16 provided on both sides of the heat exchanger 14 are box-shaped, and are once bent and protruded toward the front, which is the duct connection side, to form protrusions forming side pieces of the air outlet 17. It has pieces 18 and 19. The upper cover 20 also has an upper protrusion piece 21 that is bent to form the upper piece of the air outlet 17 and protrudes forward on the duct connection side. Also lower cover 2
2 has a lower protrusion piece 23 projecting forward and forming the lower piece of the air outlet 17 on the duct connection side. A dew pan 24 is attached to the lower part of the lower cover 22 with a metal fitting 24a, and a blower 26
A mounting plate 25 for fixing is fixed to the side plates 15 and 16 of the heat exchanger 14.

In the above configuration, when the blower 26 is operated, the air in the ceiling or the ceiling is sucked, the blower 26 ventilates the heat exchanger 14, exchanges heat with cold water or hot water, and the air is passed through the air outlet 17 to the heat exchanger 14. The air is blown into the room through a duct (not shown) connected between 17 and a ceiling air outlet (not shown).
The air outlet 17 is connected to the side plates 15 and 1 of the heat exchanger.
6, the upper cover 20, and the lower cover 22, each protrusion piece 18, 19, the upper protrusion piece 21, and the lower protrusion piece 23 are constructed.
This simplifies the process without requiring the outlet cover 5 as in the conventional case.

Effects of the Invention As is clear from the description of the above embodiment, the present invention provides projecting pieces for forming air outlets on both side plates of the heat exchanger, and on the upper cover and the lower cover, so that the side plates and the lower cover By combining the upper cover, the air outlet is formed without the air outlet cover, and therefore the structure is simplified and the weight can be reduced. Furthermore, since the number of parts is reduced, costs can be reduced.
