Abstract

PURPOSE:To make the whole device thin and compact and improve its function by a method wherein the fan case of an once-through fan is partitioned into the upper and lower parts to divide an air blasting system into two parts and one of them is formed into a ventilation passage connecting to the front side of a mainbody and the other is formed into a ventilation passage connecting to the back side of the mainbody. CONSTITUTION:An air blasting system 15 is composed of a side plate 13 forming a wall surface and a horizontal plate 14 and the other air system 17 is composed of a side plate 16 forming a wall surface and the plate 14. At the time of space cooling operation, an opening 20 at the plate 13 is closed by a door 21 and then an once-through fan 10 is started. After the fan 10 starts to rotate, an air stream flows in the direction indicated by an arrow A in the system 15 and cool air sucked from a suction hole 24 and heat-exchanged when it flows through a vaporizer 18 is discharged into the room inside through an outlet 25. In the other system 17, an air stream flows in the direction indicated by an arrow B and hot air heat-exchanged when it flows through a condenser 19 is discharged into the outside of the case. Thereby, the vaporizer and condenser are able to be accommodated compactly in the case.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an air conditioner that eliminates dead space inside a case, is compact, and has improved functionality.

(Prior art) As shown in Fig. 6, a generally used integrated air conditioner has a case 1 with a casing 2 that covers the inside of the case 1 and the front and rear parts of the air conditioner.
It is divided into two rooms, and one room 3 has an evaporator 4 and a blower fan 5.
The other chamber 6 is provided with a condenser 7 and a blower fan 8.

That is, in the above type of air conditioner, the evaporator 4 and the condenser 7 are each provided with a dedicated blower fan, and the compressor 9 forming the refrigeration cycle is made to interfere with the blower system.

(Problems to be Solved by the Invention) As described above, in the air conditioner of the type in which the evaporator and condenser are provided with dedicated blower fans, each heat exchanger and ventilation passage are formed at the front and rear, so the depth dimension is small. This has the disadvantage that the overall size of the main body becomes larger.

Therefore, the present invention has been made in view of the above points, and
In one cross-flow fan, the fan case is divided into upper and lower parts, and the ventilation system is divided into two parts, one of which is configured as a ventilation passage that communicates with the front side of the main body, and the other as a ventilation passage that communicates with the rear side of the main body,
The purpose of the present invention is to provide an air conditioner that can be made thin and compact as a whole and can improve its functionality.

[Structure of the invention]

(Means for Solving the Problems) The air conditioner of the present invention includes a cross-flow fan installed vertically on one side inside the case, and one air blower attached to the cross-flow fan that communicates with the front side of the case inside the case. a casing that forms a system and another ventilation system communicating with the rear side of the case, an evaporator disposed in one ventilation system, and an evaporator disposed in the other ventilation system and a portion of which is connected to the rear surface of the one ventilation system. a condenser arranged to face the condenser; an opening formed on one wall of the casing facing the condenser for guiding air from the condenser to the other ventilation system; and a door for freely opening and closing this opening. It consists of

(Function) In the air conditioner of the present invention, the airflow generated by the rotation of the once-through fan is transmitted through the casing to two airflow systems: one ventilation system that communicates with the indoor side and the other ventilation system that communicates with the outdoor side.
The airflow from one blower system exchanges heat as it passes through the evaporator, and is blown into the room as cold air.
The airflow from the other blowing system undergoes heat exchange as it passes through the condenser, and is discharged outside as hot air.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the state in which the case of the air conditioner according to the present invention is removed. On one side of the case, a cross-flow fan 10 such as a cross-flow fan is mounted with a shaft 11 such that the center of rotation is a vertical axis. Supported through. A casing 12 is attached to this cross-flow fan 10 to partition the air blowing system into two parts, upper and lower.

As shown in FIG. 2, the casing 12 is molded from a synthetic resin material, and includes a side plate 13 forming a wall surface and a horizontal plate 14 to form one ventilation system 15. The side plate 16 and the horizontal plate 14 form the other ventilation system 17.

One of the air blowing systems 15 has an evaporator 18 on the suction side passage of the fan 10, and the other air blowing system 17 has an evaporator 18 that straddles the suction side and outlet side passages of the fan 10 facing the back of the case. The vessels 19 are arranged respectively. The upper surface of the condenser 11 is disposed facing the rear surface of the side plate 13.

A side plate 1 facing so as to overlap the side plate 13 of the condenser 19
3, air is sent through the condenser] 9 to one side of the blower system 1.
An opening 20 is formed to lead to 5. Above opening 2
0 is provided with a door 21 for closing it.

Further, a drain pan 22 is integrally formed in a portion of the horizontal plate 14 of the casing 12 where the evaporator 18 is disposed.

In the figure, reference numeral 23 is a compressor, and 24 and 25 are an indoor air inlet and an outlet that communicate with one of the blower systems 15 formed on the front surface of the case.

The arrangement of the above-described cross-flow fan 10, evaporator 18, condenser 19, and compressor 23 in the case is as shown in the explanatory diagram of FIG. 5, viewed from the back side of the case main body.

Next, the action will be explained.

During cooling operation, the cross-flow fan 10 is started with the opening 20 provided in the side plate 13 closed by the door 21. When the cross-flow fan 10 rotates, the airflow flows in the direction shown by arrow A in one of the blower systems 15, and the cold air that is sucked in from the intake port 24 and exchanged heat as it passes through the evaporator 18 is provided in the case. The air is blown into the room through the air outlet 25.

In the other blower system 17, the airflow flows in the direction shown by arrow B, and the hot air with which heat was exchanged when passing through the condenser 19 is discharged to the outside of the case.

In addition, when dehumidifying an indoor room in a low temperature and high humidity condition such as during the rainy season, move the door 21 to open the opening and expose the upper part of the condenser 17 to one of the blowers 15 to blow the warm air through the condenser 17. This is done by sucking in the mixture with cold air through the evaporator 18.

It should be noted that the present invention is not limited to the structure of the above-mentioned embodiment, but the direction in which the wind flows in one ventilation system 15 and the other ventilation system 17 can be reversed by changing the relationship between the noses of the fan cases. You can let me.

〔Effect of the invention〕

As described above, according to the present invention, one cross-flow fan forms two ventilation systems, and the evaporator and condenser can be stored compactly in the case, making it possible to make the entire device smaller and lighter. At the same time, there is an effect that the dehumidifying operation function can be loaded.
