Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an air conditioner of a type in which an indoor unit and an outdoor unit are integrally incorporated.

(Prior Art) As an air conditioner, a type in which an indoor unit and an outdoor unit are integrally incorporated is known, and in an ordinary house or the like, it is called a window type installed in a window opening portion. The type of air conditioner is widely used. In such an air conditioner, if an intake / exhaust port for outdoor air is opened on the back surface exposed to the outside, rainwater penetrates into the airframe through this opening, and metal parts inside are corroded. This may cause an adverse effect that shortens the life of the device. Therefore, in general, a box-shaped chamber is attached to the lower part of the body of the wind-type air conditioner, and a duct is connected to the intake and exhaust ports on the outside of the air conditioner, and this duct is communicated with the inside of the chamber.
The structure is such that the tip of a bellows-shaped duct connected to the lower surface of the chamber is opened to the outside of the room. In this way, the intake and exhaust passages on the outdoor side are routed to the side of the bottom surface of the machine body to prevent rainwater from entering the machine body.

(Problems to be solved by the invention) However, when such a structure is adopted, the intake / exhaust passage portion up to the chamber and the intake / exhaust passage portion from the chamber to the outdoor opening become extra long, and these intake / exhaust passages are There are many bends. Therefore, the amount of work required for the air conditioner blower increases, and the power consumption of the electric motor for the blower increases accordingly, causing a problem that the energy consumption efficiency of the air conditioner as a whole decreases. Will end up. In addition to this, there is an adverse effect that the volume or height of the entire machine body is increased by the amount of the chamber attached to the lower part of the machine body.

The present invention has been made in order to eliminate such a conventional drawback, and an object thereof is to realize an air conditioner that does not require a bent long outdoor intake and exhaust passage and a chamber.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an air conditioner of a type in which an indoor unit and an outdoor unit are integrally incorporated in the same housing. A compressor is arranged at a substantially central position in the direction, an indoor unit is arranged at an upper position of the compressor, and an outdoor unit is arranged below the compressor. In addition, an intake / exhaust passage for outdoor air that penetrates the bottom surface of the housing and communicates with the outdoor unit is formed.

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

1 and 2 are views of the inside of the air conditioner of the present embodiment as viewed from the side and the front side, respectively, and FIG. 3 is a view showing the bottom surface thereof. As can be seen from these drawings, the air conditioner 1 of the present example has a housing 2 having a vertically long rectangular parallelepiped shape, and each component is incorporated in the housing 2. That is, in the internal space of the housing 2, three vertically-arranged compartments 5, 6 and 7 are formed by the two steel plate support plates 3 and 4 which are horizontally arranged vertically. A compressor 8 is arranged in the central compartment 6, and an indoor heat exchanger 9 constituting an indoor unit and an indoor blower 13 including an impeller 11 and a casing 12 covering the impeller 11 are arranged in the upper compartment 5. Has been done. In the lower compartment 7, the outdoor heat exchanger 14 that constitutes an outdoor unit and the impeller 1
An outdoor blower 17 including 5 and a casing 16 covering the same is disposed.

The housing 2 includes a front plate 21 and a rear plate 2 made of steel plate.
2, the left and right side plates 23 and 24, the top plate 25, and the bottom plate 26. These plates have a vibration-proof and sound-absorbing structure in which butyl rubber and a sound-absorbing material are laminated and adhered on the inner surface. Support plate 3 placed horizontally in the housing 2,
Reference numeral 4 has flanges 3a and 4a formed by bending their outer peripheral edges upward at a right angle, and they are respectively joined to the inner surface of the side plate of the housing 2 at this position.

The compressor 8 arranged in the central compartment 6 is supported on the support plate 4 via four support devices 27. The main components of these support devices 27 are a bracket 27a that directly supports the compressor 8, a vertical shaft 27b that supports the compressor 8 slidably up and down, and a rubber bush 27c that suppresses vertical movement of the bracket 27a. It has a vibration-proof structure that absorbs the vibration of the machine 8 and does not transmit it to the housing 2 side.

On the other hand, the upper compartment 5 is vertically divided by a partition plate 31 made of a steel plate, and the blower 13 is fixed to the upper side. A blowout passage 32 communicating with the casing of the blower by the partition plate 31 and the inner peripheral surface of the housing 2.
Is defined and formed, and the passage 32 communicates with an outlet 33 attached to the front surface of the front plate 21 of the housing. Further, below the partition plate 31, the indoor heat exchanger 9 is attached in a state where the housing front plate 21 side is lifted, and the indoor air suction port 34 communicates with the front position of this exchanger 9. There is. Furthermore, the partition plate 31 has
An opening 31a communicating with the side on which the lower heat exchanger 9 is arranged is formed at a position facing the suction port of the blower 13. Here, on the upper surface of the support plate 3 below the heat exchanger 9,
A dehumidified water receiving surface 35 is formed so as to be inclined downward from the air suction port 34 side toward the rear surface side of the housing, and the water dropped from the heat exchanger 9 to the receiving surface 35 is along the receiving surface. It flows to the back side. At the rear end of the receiving surface, an upper end opening 36a of a vertical drain pipe 36 that extends in a state of penetrating the two support plates 3 and 4 is opened, and flows into the pipe 36 from the receiving surface 35 through this. Water is discharged to the outside from a drainage port 29 on the side surface of the housing bottom plate 26.

Next, the outdoor heat exchanger 14 arranged in the lower compartment 7 in the housing 2 has an elbow shape bent substantially at a right angle when viewed from the side, and the upper end side thereof is the support plate 4
Is attached to a position near the front plate on the back surface of the, and the lower end thereof is attached to a duct 41 forming a blowout passage connected to the outdoor blower casing 16. As shown in FIG. 3, the housing bottom plate 26 is formed with an outdoor exhaust port 26a at a position where the lower end opening 41a of the duct faces, and at a position directly below the bent portion 14a of the heat exchanger 14. An outdoor air intake port 26b is formed. The lower end opening 41a of the duct is connected to the outdoor exhaust port 26a.

Here, the water dropped from the heat exchanger 14 is discharged between the intake port 26b formed in the housing bottom plate 26 and the bent portion 14a of the heat exchanger in a state of being bridged over the housing front plate 21 and the housing bottom plate 26. A dehumidified water receiving member 42 made of a steel plate is arranged for this purpose. As can be seen from the figure, the receiving member 42 is bridged between the front plate 21 and the bottom plate 26 at an inclination angle of about 45 degrees, and a plurality of step portions 43 are formed. Each of these stepped portions has a tread surface portion 43a which is set to an inclined surface slightly inclined from the horizontal direction toward the bottom surface 26 side. Also, the riser surface portion 43b is such that the lower side is the housing front plate 2
It is set so as to form an inclined surface that is slightly inclined toward the 1 side from the vertical direction. Furthermore, these steps 4
As can be seen from FIG. 2, the three riser surface portions 43b are provided with two openings 43c along the riser surface portions 43b, two openings 43c for each riser surface portion. The air sucked from the outdoor air intake port 26b formed in the housing bottom plate 26 is introduced to the heat exchanger 14 side through these openings 43c. In addition, in FIG. 1 and FIG. 2, 44, 45, and 46 are piping for forming a refrigerating cycle. Further, a bottom substrate 30 is provided below the housing bottom plate 26 via a vibration-proof rubber 29.

The air conditioner 1 of this example configured as described above is arranged, for example, in a bay window portion of a house as shown in FIG. That is, in the bay window portion 52 of the house 51, the air conditioner 1
Is installed in a space 57 surrounded by the counter top plate 53, the outer wall 54, the indoor side wall 55, and the floor plate 56 in the bay window portion. An exhaust duct 57 and an intake duct 58, which extend through the floor plate 56 and extend below the floor, are connected to the exhaust port 26a and the intake port 26b opened in the bottom plate 26 of the air conditioner, respectively. Intake and exhaust are performed as indicated by the arrow. In addition, the intake port 34 on the indoor side
An opening 55a communicating with the indoor side 59 is formed in the portion of the indoor side wall 55 that faces the outlet 33, through which air is sucked and discharged.

In the cooling operation of the air conditioner 1 installed at this position, the heat energy in the air sucked from the indoor side 59 is removed by the heat exchanger 9 arranged in the upper compartment 5 in the housing. The thermal energy extracted from the air on the indoor side is released to the outdoor 60 by using the air exhausted through the exhaust port opened on the bottom surface of the housing as a medium. In the heating operation, conversely, heat energy is taken from the outdoor air, and this is absorbed by the indoor air to the indoor side 5.
Is released to 9. Since such an operation is well known, further description will be omitted.

Here, the compressor 8 during such cooling or heating operation
The vibration generated due to the driving of is absorbed by the supporting device 27 of the vibration-proof structure supporting the vibration. Furthermore, the vibrations that are not absorbed by these support devices 27 are absorbed by the support plate 4 that supports these support devices 27. As described above, in this example, since the compressor 8 is supported by the double vibration isolation mechanism including the support device 27 and the support plate 4, there is an advantage that the vibration of the compressor and the accompanying noise can be sufficiently prevented. is there. On the contrary,
For example, when the compressor is arranged in the lower compartment of the air conditioner housing, such a double vibration isolation structure cannot be adopted, so it is difficult to obtain the effect of this example. . The anti-vibration rubber 29 provided between the housing bottom plate 26 and the bottom substrate 30 mainly functions to absorb the vibration generated by the blower.

Further, since the compressor is arranged between the indoor heat exchanger and the outdoor heat exchanger in this manner, the pipes connecting these compressors are different from the case where the compressor is arranged below the housing, for example. There is also an effect that it can be shortened as a whole.

Furthermore, when the air conditioner 1 is in operation, the water condensed on the heat exchangers 9 and 14 drops on the receiving surface 35 and the receiving member 42. Of these, the water dropped on the receiving member 42 is fluidized along the stepped portion 43 of this member. As described above, in the step portion 43, the angles of the tread surface portion and the riser surface portion of the step portion are set to angles slightly inclined from horizontal and vertical. Therefore, the water that flows down from the tread surface portion 43a to the riser surface portion 43b does not drop from the opening 43c opened in the riser surface portion 43b to the bottom surface of the housing, but drops onto the tread surface portion 43a of the lower step. In this way, the water dropped from the heat exchanger 14 moves to the lower end of the receiving member 42 and falls on the upper surface of the bottom plate 26 without flowing down from the ventilation opening 43c formed in the receiving member 42, and is provided there. It is discharged to the outside of the air conditioner 1 through the drainage port 28. Thus, if the receiving member 42 of this example is used,
There is an advantage that water can be appropriately discharged while ventilating.

It should be noted that although the above description has been directed to an air conditioner that performs cooling and heating, the present invention can of course be applied to a cooling-only machine or a heating-only machine.

(Effect of the Invention) As described above, in the air conditioner of the present invention,
The compressor is arranged in the central portion of the air conditioner housing, and the outdoor unit is arranged in the lower portion. Therefore, according to the present invention, the housing bottom plate can be pierced and opened to a position where rainwater does not enter from the outdoor side without lengthening the intake passage and the exhaust passage of the outdoor air extending from the outdoor unit. It is possible to eliminate the loss of energy consumption that occurs due to the lengthening of the intake and exhaust passages. Further, by arranging the compressor between the indoor equipment and the outdoor equipment in this way, there is also an effect that the pipe connecting these three can be shortened. Furthermore, by arranging the compressor in the central portion, it is possible to take measures such as supporting the compressor with a double anti-vibration mechanism, so that vibration of the air conditioner caused by the compressor occurs. There is also an effect that can easily be suppressed.
