Abstract

PURPOSE:To form an air flow of air intake type for a heat exchanger and aim at noise reduction by providing a water drop collection vane of shape, a first water receiving tray which forms a first air passage hole, a water receiving groove which collects and stores condensation water falling from the first air passage hole, and a second water receiving tray which forms a second air passage hole. CONSTITUTION:The condensed water falling in drops from a heat exchanger 14 is received by the water drop collecting vanes 21 of a first water receiving tray 18 and the water follows the inclination of the water collecting vanes 21 of a shaped cross section to trickle to second water receiving grooves 22 of a second water receiving tray 24, and the water is stored there. Then the water is discharged to outside. The air flow by a fan 16 driven by an electric motor 17 is sucked from a suction opening 13 as an intake hole into a second air passage hole 23 provided among a plurality of water receiving grooves of the second water receiving tray 24, and then flows to a heat exchanger 14 via the first air passage hole 20 between the water drop collecting vanes 21 with a shaped cross section and the air is discharged from a discharge opening 12 via the blower casing 15. The flow of the sucked air realizes a blower system of suction air type, and noise reduction can be thereby attained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner in which a heat exchanger is arranged horizontally.

Conventional technology In recent years, there has been a gradual increase in demand for air conditioners that are embedded in the walls or ceilings of living spaces because when they are installed, they spoil the aesthetics of the living space and give the occupants a feeling of pressure. It's increasing.

An example of a conventional ceiling-embedded air conditioner will be described below with reference to the drawings.

Figure 5 shows the external tie and g+ of a conventional ceiling-mounted air conditioner.
Figure 6 is an enlarged sectional view of the main parts of the air conditioner.

The operation of the ceiling-embedded air conditioner configured as above will be described below.

Air sucked in from the suction port 3 via the blower casing 5 by the fan 6 rotated by the electric motor 7 passes through the heat exchanger 4 and then is blown into the room from the Suita outlet 2.

A conventional example of such a configuration is, for example, a ceiling-embedded air conditioner disclosed in Japanese Patent Application Laid-Open No. 60-78242.

Problems to be Solved by the Invention However, in the configuration as described above, the so-called blowing method in which the sucked air is collided with the heat exchanger 4 by the 7 mm 6 is not a method that is generally known. Since the turbulent air flow sent out from the fan 6 collides with the fin edges of the heat exchanger 4 as shown in FIG.

In view of the above-mentioned problems, the present invention aims at reducing noise by creating a so-called intake type air flow in a heat exchanger.

Means for Solving the Problems The air conditioner of the present invention which solves the above problems has a fan driven by an electric motor, and a heat exchanger horizontally disposed on the F75 of this fan, which is essentially exchangeable. ``to'' below the container

Water can be stored by dripping into the water receiving groove of the water receiving tray. On the other hand, the flow of intake air is caused by the fan to be sucked in and leaked from the second ventilation hole provided between the plurality of water receiving grooves of the second water receiving tray, and further to the first water receiving tray. Water droplets flow through the first ventilation holes between the collecting vanes to the heat exchanger, and can realize an intake-type ventilation system for the so-called heat exchanger. The machine will be explained with reference to the drawings.

The figure shows an external perspective view of the second water tray 24 described in "1".

The operation of the ceiling-embedded air conditioner configured as described above will be explained using FIGS. 1, 2, 3, and 4.

With the above configuration, the heat exchanger 14 arranged horizontally
The condensed water dripping from the first water pan 18 is first received by the water drop collection blade 21 of the first water pan 18, and after being applied to the slope of the water drop collection vane 21 that forms a "he"-shaped cross section, the condensed water is further collected by the second water pan 24 at C.
The water receiving groove 22-... can drip water, store it, and discharge it to the outside.3 On the other hand, the air flow (the fan 16 driven by the electric motor 17 enters the inlet 13). , water droplets are sucked in from the second ventilation holes 23 provided between the plurality of water receiving grooves 22 of the second water receiving tray 24, and are further drawn into the water droplet collection blade 21 having an "E"-shaped cross section of the first water receiving tray 18. The heat exchanger 14 is connected to the heat exchanger 14 through the first ventilation hole 20 between them.
The air can be blown out from the air outlet 12 via the blower casing 15.

Effects of the Invention As described above, according to the present invention, the condensed water dripping from the horizontally arranged heat exchanger is received by the water droplet collecting blades of the first water tray so as to be distributed to the left and right, and then the condensed water is distributed downwardly. Second
Water can be stored in the water receiving groove of the water receiving tray.On the other hand, regarding the flow of intake air, there is a second water receiving groove between the water receiving grooves of the second water receiving tray.
By forming a ventilation hole and further forming a first ventilation hole between the water droplet collection vanes of the first water pan, water flows from the suction port to the second ventilation hole, the first ventilation hole, and the heat exchanger. A so-called suction type blower system can be realized, and as compared to a generally known blowing type blower system against a heat exchanger, it is possible to achieve lower noise.

In addition, in the embodiment, an example of a ceiling-embedded air conditioner is shown, but it is a matter of course that the structure of the tree-squeezing system can be applied to a ceiling-mounted air conditioner as well.
