Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air conditioner mounted on a ceiling of a building such as a house, for example, and relates to an air conditioner in which an electric box is integrally attached to the air conditioner.

[0002]

[Prior art]

 Conventionally, an electric box for housing electric components for controlling an air conditioner is attached to the outer wall side of the case so as to extend further in the longitudinal direction of the ceiling-mounted air conditioner (actual opening 3). -103921) and a ceiling-mounted air conditioner attached to the inner wall side of the case from one end in the longitudinal direction along the longitudinal direction (see Japanese Utility Model Laid-Open No. 2-77509). .

Further, as shown in FIG. 6, in the case 2 of the air conditioner main body 1, the air sucked from the air suction port 16 bends to the heat exchanger 3 at a steep angle, and then the heat is transferred to the heat exchanger 3. It had a flowing structure.

[0004]

[Problems to be solved by the device]

 However, in the air conditioner integrated with the electric box cited above, it is necessary to increase the longitudinal dimension of the entire ceiling-mounted air conditioner by the width of the electric box.

For this reason, in some types of houses, the space between the ceilings of the ceiling is narrower than in ordinary houses, so when installing a ceiling-mounted air conditioner in a direction perpendicular to the ceiling, There was a problem that we had to cut the ties.

On the contrary, if the ceiling-mounted air conditioner is installed without cutting the field edge, the ceiling-mounted air conditioner must be downsized, which reduces the area of the air intake port. However, there was also a problem that the wind speed of the intake air increased and noise was generated.

Further, in the air conditioner as a whole, the wind speed distribution of the air passing through the heat exchanger is greatly different between the upper and lower sides as shown in FIG. 6, so that the heat exchange of the passing air cannot be appropriately performed. was there.

In view of the above problems, the present invention can be installed in a right angle direction between narrow rims of the ceiling without cutting the rim while maintaining the area of the air suction port, and heat exchange can be performed. The purpose is to provide an air conditioner in which the wind speed of the air passing through the device does not change substantially between the upper and lower sides.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, an air conditioner according to the present invention comprises a case in which an air inlet and an air outlet are formed on the same surface, and at least an electric box and a heat exchanger are housed in the case. The heat exchanger is arranged such that the ventilation passage inlet end face has a predetermined angle with the air suction port, and the electric box extends from the air suction port to the front side of the heat exchanger. And a guide surface provided between the air suction port and the air passage inlet end surface of the heat exchanger, which is the most distant side.

[0010]

[Action]

 Therefore, it is not necessary to increase the length of the ceiling-mounted air conditioner by the width of the electric box, and the air sucked from the air suction port is bent along the guide surface of the electric box at a gentle angle to generate heat. Since it flows to the exchanger side, air can pass through the heat exchanger at almost the same wind speed between the upper and lower sides as shown in FIG. Therefore, the above problems can be achieved.

[0011]

【Example】

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

1 to 3 show the configuration of a ceiling-mounted air conditioner according to the present invention.

The air conditioner body 1 includes a box-shaped case 2 having a hollow inside, an air guide member 15 arranged in the case 2, a heat exchanger 3 connected to an upstream side of the air guide member 15, The heat exchanger 3 comprises at least the air conditioner such as the blower 20 and the drain pan 10, the drain pump 11, the electric box 35, and the like, which are located on the downstream side of the heat exchanger 3 and are housed in the air guide member 15.

The air guide member 15 is for guiding the air taken in from the air suction port 16 and temperature-controlled by the heat exchanger 3 to the air outlet 17, one end of which is provided in the heat exchanger 3. It extends to the ventilation passage inlet end face 3 a and the other end is connected to the air outlet 17. Since the air inlet 16 and the air outlet 17 are ceiling-mounted, they are both formed downward on the lower surface 2f. In addition, an air filter 18 is provided on the side of the air suction port 16 in order to prevent dust from entering.

The heat exchanger 3 has an expansion valve, a condenser, a compressor and pipes existing outside the air conditioner main body 1 by connecting inlet / outlet pipes to inlet / outlet portions 4 and 5 protruding from the side wall 2 a of the case 2. Since they are combined to form a cooling cycle and are of a heat pump type, heating or cooling of air can be switched.

Further, the heat exchanger 3 is arranged so as to shield the entire inner width of the air guide member 15, and the outer width of the heat exchanger 3 has a longitudinal dimension substantially equal to the inner width of the air suction port 16. I have it.

The heat exchanger 3 is arranged so that the ventilation passage inlet end surface 3 a is at a right angle to the air suction port 16, but the present invention is not necessarily limited to this, and heat exchange of suction air is appropriately performed. For example, they may be arranged at any angle.

A drain pan 10 is disposed below the air guide member 15 of the heat exchanger 3 as a drain water tray to temporarily store the drain water. Further, for absorbing the drain water stored in the drain pan 10, a drain pump 11 is provided on the drain pan 10 and on the side wall 2a side of the heat exchanger 3 to prevent the drain water from overflowing from the drain pan 10. ing.

Then, the drain water sucked up from the drain pump 11 via the pipe connecting portion 12 extending from the drain pump 11 is discharged to the outside of the air conditioner body 1 through the drain water discharge pipe. A heat insulating material 13 covers the periphery of the pipe connecting portion 12 in order to block heat from the drain water.

The blower 20 is arranged in parallel with the heat exchanger 3 and employs a cylindrical cross-flow fan, and the length of the blower 20 in the longitudinal direction is longer than that of the heat exchanger 3. It is the same as the direction dimension.

The blower 20 covers one end of the shaft 21 with a bearing bracket 23 and then rotatably engages with the plate 24, and the other end of the shaft 21 protrudes from the space 32 of the case 2. Since it is connected to the motor 22 installed in, the rotation speed of the blower 20 can be controlled by the motor 22.

A louver 28 having a plurality of slanted blades 26 fixed to a shaft 27 having both ends rotatably locked to the air guide member 15 is disposed directly below the blower 20, By rotating the shaft 27 manually to change the direction of the blade 26, the direction of the blown air can be changed to the left or right. Further, a louver 29 that can be rotated by a shaft 30 is also arranged near the outlet 17, and the direction of the blown air can be changed up and down by automatically changing the inclination of the louver 29. Therefore, the louvers 28 and 29 allow the user to freely change the direction of the blown air according to his taste.

The electric box 35 is for accommodating electric equipment for controlling the air conditioner, and the side wall 2 c and the end of the upper wall 2 e that intersects the side wall 2 c at right angles to the heat exchanger 3 Up to the ventilation passage inlet end face 3a, and an inclined surface 60 provided between the air suction port 16 and the heat exchanger 3 between the farthest sides of the ventilation passage inlet end face 3a. It is provided in the case 2 in the form of a triangular prism extending integrally along the longitudinal direction.

Therefore, the electric box 35 has an inverted triangular shape in cross section whose lateral width increases toward the heat exchanger 3 side toward the upper side. The length of the electric box 35 is substantially the same as the length of the air suction port 16. The inclined surface 60 is not limited to the flat surface as shown in FIGS. 2 and 3, and may be a curved surface.

As a result, the air taken in from the air suction port 16 flows along the inclined surface 60 of the electric box 35, so that the air is bent toward the heat exchanger 3 side at a gentle angle. Further, since the electric box 35 is housed inside the case 2 so as to face both the side wall 2c and the upper wall 2e that intersect at a right angle, the longitudinal dimension of the air conditioner body 1 is increased by the width of the electric box. It can be prevented.

Finally, the mounting of the air conditioner body 1 will be described with reference to FIGS. 4 and 5. One end of the bracket 40 is provided on the side walls 2c and 2d of the case 2 in pairs, one end of which is the ceiling upper surface 50. It is carried out by fitting the hanging bolt 41 fixed to, and then sandwiching and fixing with a nut or the like. As a result, the air conditioner body 1 is suspended from the ceiling upper surface 50 to the ceiling opening 48 formed in the ceiling lower surface 49. The ceiling opening 48 has substantially the same size as the air conditioner body 1.

Then, after connecting the inlet / outlet pipes from the side of the ceiling opening 48 to the inlets / outlets 4 and 5, and connecting the pipe for drain water discharge to the pipe connecting portion 12, a pipe having a size smaller than that of the ceiling opening 48 is connected. A large ceiling panel 42 is attached to cover the ceiling opening 48. This completes the installation of the ceiling-mounted air conditioner on the ceiling.

[0028]

[Effect of device]

 As described above, according to the present invention, it is possible to prevent the longitudinal width of the air conditioner body 1 from increasing in the longitudinal direction by the width of the electric box. Even if the air conditioner is installed, it is not necessary to cut the field.

Further, for the same reason, it is not necessary to downsize the air conditioner main body and the area of the air suction port can be maintained. Therefore, it is possible to prevent noise from being generated by increasing the wind speed of the intake air.

Further, since the air taken in from the air suction port bends and flows toward the heat exchanger at a gentle angle, the wind speed hardly changes above and below the heat exchanger, and the passing air is appropriately heat-exchanged. it can.
