Abstract

PROBLEM TO BE SOLVED: To effectively prevent the generation of condensate by integrally molding a guide means for so guiding condensate as to flow without staying at the position covering the shaft of a fan with a plinth at the time of draining the condensate collected at the plinth to a supply grill in an air conditioner having the plinth for collecting the condensate. SOLUTION: In the air conditioner which has a fan, a heat exchanger 4, a supply grill 5 having a water receiving tray for supplying the heat exchanged air and a plinth 1 for collecting the condensate by the exchanger 4, guide means for so guiding the condensate to flow without staying at the position covering the shaft for coupling a fan to a fan motor at the time of draining the condensate collected at the plinth 1 to the grill 5 is integrally molded with the plinth 1. Thus, the condensate can be fed to the tray of the grill 5 rapidly without staying at any place. An air layer is so formed at the plinth 1 as not to generate the condensate in an air circuit due to the cooling of the passage at the time of feeding the condensate.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dew condensation water treatment device for an air conditioner.

[0002]

2. Description of the Related Art In recent years, in a separate type air conditioner indoor unit, space saving installation is possible and high performance is required.

An underframe, a fan, a heat exchanger for exchanging heat of the air sucked by the fan, and a blowout grill for blowing the heat-exchanged air are provided.
The bent shape of the heat exchanger is complicated for compactness and high performance, and the dew condensation water generated during heat exchange in the heat exchanger on the underframe side is discharged to the blowing grill.

An example of the deformation due to the temperature of the underframe during operation of a recent separate type air conditioner will be described below with reference to the drawings.

FIG. 3 is a cross-sectional view showing the flow of air during operation of a conventional indoor unit. Reference numeral 1 is an underframe of the indoor unit, 4 is a heat exchanger that is folded in three, and 5 is a blowing grill.

The dew condensation water from the heat exchanger 4 is accumulated on the underframe 1 and flows down to the blowing grill 5.

[0007]

In the above-mentioned structure, the shaft connecting the fan motor and the fan motor that drives when the dew condensation water generated during the heat exchange of the heat exchanger on the rear surface of the underframe drains to the blowing grille. Stagnation in the area that covers the part,
There was a problem that the underframe was cooled and dew condensation occurred on the wind circuit side on the back side.

An object of the present invention is to speed up the flow of dew condensation water and prevent dew condensation on the wind circuit side.

[0009]

In order to solve the above-mentioned problems, in order to solve the above-mentioned problems, there is provided a guide means for guiding the condensed water which is accumulated on the underframe so that the condensed water flows without stagnation. It is provided integrally with the underframe.

In the second aspect, when the condensed water accumulated on the underframe of the first aspect is discharged to the blowing grille, the passage through which the condensed water flows is cooled so that the air layer is formed so that the condensation does not occur in the wind circuit. It is provided integrally with the underframe.

[0011]

According to the present invention having the above-described structure, in (claim 1), when the condensed water accumulated on the underframe is discharged to the blowing grill, the condensed water connects the fan motor and the fan motor that drives the fan motor. It is for flowing quickly without stagnation when flowing through the part covering the shaft part. In (claim 2), a part of the underframe which is the passage is cooled by the dew condensation water to cause dew condensation in the wind circuit on the back side. It can be prevented from occurring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An air conditioner according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front perspective view of an indoor unit of a separate type air conditioner in one embodiment of the present invention, and FIG. 2 is a transverse sectional view.

In FIG. 1, 1 is an underframe of an indoor unit, 2 is a fan, 3 is a fan motor for driving the fan, and 4 is a fan motor.
Is a heat exchanger for exchanging heat of the sucked air, and 5 is a blowing grill for blowing the air having undergone the heat exchange.

In the first aspect, the fan 2, the heat exchanger 4, the blowing grill 5 having a water tray for blowing the heat-exchanged air, and the condensed water received by the heat exchanger are accumulated. In the air conditioner equipped with the underframe 1, when the condensed water accumulated on the underframe 1 is discharged to the blowing grille 5, the dewed water can be smoothly deposited on the portion covering the shaft connecting the fan 2 and the fan motor 3. A guide means is provided integrally with the underframe 1 so that the water can be swiftly flowed to the water pan of the blowing grill 5 without accumulating anywhere by making a concentric shape into a slope for guiding the flow. With such a configuration, the dew condensation water can quickly flow down to the blowing grill 5 by the guide means of the underframe 1.

In (claim 2), as shown in FIG. 1, the fan 2, the fan motor 3, the heat exchanger 4, and the water tray for blowing the air having undergone heat exchange in (claim 1) are provided. In the air conditioner including the blowing grille 5 and the underframe 1 that receives and accumulates the dew condensation water from the heat exchanger, when the dew condensation water accumulated by the underframe 1 drains to the blowing grille 5, the fan 2 and the fan An air layer is integrally formed on the underframe 1 so that the passage is cooled when the condensed water flows through the portion covering the shaft portion connecting the motor 3 and the condensed water is not generated in the wind circuit. With such a configuration, even if the dew condensation water is very cold, only the surface of the underframe is cooled, and dew condensation on the back surface does not occur.

[0017]

As described above, according to the present invention (claim 1), the fan 2 and the fan motor 3 are connected to each other when the condensed water accumulated on the underframe 1 is discharged to the blowing grill 5 during the cooling operation. When the dew condensation water flows through the portion covering the shaft portion, the dew condensation water can be swiftly flown to the grill, and in (Claim 2), the temperature of the dew condensation water is insulated by the air layer, the passage is cooled, and the dew condensation occurs in the wind circuit. Is to prevent the occurrence of.
