Description

[Detailed explanation of the idea] Industrial applications The present invention relates to improvement of air conditioners.

Conventional technology A conventional air conditioner has a cooling heat exchanger installed above the box body, a heating heat exchanger below the heat exchanger, and a blower fan below the heat exchanger and the bottom of the box body. In addition, they are arranged in a box so as to be stacked.

Problems to be Solved by the Invention According to the above configuration, especially when the cooling heat exchanger and the heating heat exchanger are arranged vertically, the product dimensions have a wide range of depths corresponding to the sizes of the parts. Therefore, there was a problem that it lacked rationality in today's world where miniaturization is required.

Means for Solving the Problems The present invention was made to eliminate the above-mentioned drawbacks, and the upper part of the cooling heat exchanger is arranged at an inclined rearward height, and the heating heat exchanger is arranged parallel to the lower part of the rear surface. A space recess is provided in the space formed between the heating heat exchanger and the back wall of the box, and the direction of rotation of the ventilation fan is rotated from bottom to top toward the front of the box. It was formed like this.

Effect With the above configuration, the heating heat exchanger is installed in the space formed below the cooling heat exchanger arranged at an angle, so the vertical dimension is almost that of the cooling heat exchanger. The size, height and depth can be reduced, and the wall surface of the space recess, which is partially parallel to the back of the heating heat exchanger, reduces the passage area of the blower fan air and allows the heating heat exchanger to be Air is blown in parallel to the multiple parallel pipes that make up the exchanger, improving thermal efficiency, and since the air supply and exhaust pipe can be installed in the recessed space, the space between the air conditioner and the wall can be narrowed, making it more compact. It is possible to save space.

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

The configuration of the embodiment is as shown in FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a cooling heat exchanger, which is located at the upper part of the box 8 and whose upper part is inclined toward the rear side of the box 8. A heating heat exchanger 2 is formed by arranging a plurality of tubes in parallel, and one end of each tube is connected to a burner 6, and the other end is connected to an exhaust port 7. This heat exchanger 2 for heating is arranged below and parallel to the heat exchanger 1 for cooling. 3 is a ventilation fan installed at the bottom of the box body 8;
The rotating shaft (not shown) is positioned horizontally, parallel to the pipes of the heating heat exchanger 2, and the rotating direction is as shown by the arrow, so that the rotating shaft rotates from bottom to top toward the front of the box 8. The discharge port 3A is opened upward. Reference numeral 4 indicates an inlet for sucking air flowing by the drive of the blower fan 3, and reference numeral 5 indicates an outlet for discharging cold and hot air with which heat has been exchanged. 9 is a space recess,
It is provided in the space formed between the rear inclined surface of the heating heat exchanger 2 and the back wall of the box body 8, and a part of the wall surface forming the space recess 9 is located on the back surface of the heating heat exchanger 2. The other end is connected to the discharge port 3A and is provided on the back side of the box body 8. Reference numeral 10 denotes a back cover, which is used to secure arbitrary dimensions between the box body 8 and the wall 11 which is the back structure. Reference numeral 12 denotes an air supply and exhaust pipe, which has a double air supply and exhaust pipe structure, with one end passing through the wall 11 to the outside, and the other end being an air supply pipe, that is, an outer cylinder connected to a combustion blower (not shown). The burner 6 has an exhaust pipe, that is, an inner cylinder, which is connected to the exhaust port 7. The indoor side of this air supply and exhaust pipe 12 is located between the space recess 9 and the wall 11.

Next, the operation of this embodiment having the above configuration will be explained.

During cooling operation, refrigerant flows into the cooling heat exchanger 1, and then the blower fan 3 is driven, and the air flows from the suction port 5, through the blower fan 3, the heating heat exchanger 2, and reaches the cooling heat exchanger 1. Heat is exchanged here, and the cooled air passes through the outlet 4 and exits into the room for cooling. During the heating operation, the burner 6 burns the gas, and the high-temperature combustion gas reaches the heating heat exchanger 2, which is composed of a plurality of pipes, and the exhaust port 7, and is discharged outdoors. Next, the blower fan 3 is driven to send air to the heating heat exchanger 2 in the same way as during cooling operation, where the air is exchanged heat and becomes warm air, which passes through the cooling heat exchanger 1 and the air outlet 4 and exits into the room. and perform heating. Here, in order to efficiently send air to the heating heat exchanger 2, the space recess 9 provided in the box body 8 plays an important role. That is, the wind flows along the heating heat exchanger 2. Furthermore, the wall surface forming the space recess 9 has a shape that extends inward from the upper part to the lower part, and a space is formed between it and the rear wall of the box body 8, and an exhaust pipe 12 for discharging combustion gas outdoors is attached to this part. Therefore, the back cover 10 can be small and the thickness of the product can be reduced.
Because of the above, since the heating heat exchanger 2 is arranged in the space formed below the cooling heat exchanger 1 which is tilted, the vertical height dimension is almost the same as that of the cooling heat exchanger 1.
The indoor side of the exhaust pipe 12 is housed in the box 8, and the height and depth including the back cover 10 can be reduced.

Effects of the invention As described above, according to the invention, the cooling heat exchanger is arranged diagonally, the heating heat exchanger is provided below and parallel to the cooling heat exchanger, and there is a space recess on the back side of the box. By forming this, the height and depth of the product can be reduced, which has the effect of saving space.
