[0003]

In recent years, there has been a demand for an air conditioner for air-conditioning a relatively small space other than a living room such as a toilet or a sanitary room such as a toilet.

Therefore, it is conceivable to use the above-mentioned conventional air conditioner in a non-room such as a washroom. However, in this case, the air conditioning capacity is excessive, the initial cost and the running cost are increased, and the air Since the harmony device itself is large and heavy, there are various problems that it is difficult to secure a mounting space.

The present invention has been made in view of such circumstances, and an object thereof is to provide a low-cost and compact air conditioner capable of comfortably air-conditioning a relatively small space such as a washroom. It is in.

[0006]

According to the first aspect of the present invention, there is provided a refrigeration cycle in which a compressor, an outdoor heat exchanger, a decompressor, and an indoor heat exchanger are sequentially communicated to circulate a refrigerant, an indoor fan and an indoor fan. An indoor air inlet that accommodates the indoor heat exchanger and sucks indoor air, and an indoor air outlet that blows indoor air that has passed through the indoor heat exchanger, and the compressor, the decompressor, and the outdoor An outdoor unit having a fan, an outdoor air inlet that houses the outdoor heat exchanger and sucks the external air, and an outdoor air outlet that blows the external air that has passed through the outdoor heat exchanger to the outside;
A partition partitioning the interior and the interior of the room, a damper formed in the partition to open and close a communication hole that communicates the interior with the exterior, and an outdoor cabinet installed on an exterior wall surface; An indoor cabinet, which has an intake grill for inhaling air and a blowout grill for blowing out conditioned air, is provided in a room, and penetrates a wall surface. A straight duct communicating with the suction port and the indoor outlet, respectively.

According to the present invention, the air conditioning operation can be performed by closing the communication hole by the damper and operating the indoor fan, the outdoor fan, and the compressor. Thus, the air-conditioned space can be comfortably air-conditioned. Further, the interior cabinet mounted on the inner surface of the interior wall of the interior wall has an extremely simple configuration in which only the intake grill and the outlet grill are opened, so that the interior cabinet can be reduced in size, thickness, and weight. .

Accordingly, the space for mounting the indoor cabinet on the inner surface of the mounting wall on the indoor side can be largely saved, and the amount of projection into the room can be reduced. For this reason, the indoor cabinet can be mounted in a relatively small non-room space such as a washroom or a toilet with a small space.

[0009] The duct is straight, and penetrates the mounting wall of both the indoor and outside cabinets in a straight line in the thickness direction, and connects the suction grill and the blow grill of the indoor cabinet to the interior of the indoor cabinet. Since it is only necessary that the duct and the indoor air outlet communicate with each other in a straight line, the duct and the outdoor cabinet can be integrated, and the length of the duct can be reduced. For this reason, the pressure loss due to the duct can be reduced. Further, since the diameter of the opening of the duct can be reduced, the diameter of the through-hole in the mounting wall such as the side wall such as a washroom for inserting the duct can be reduced. In addition, since the indoor and outside cabinets are connected to each other by the straight ducts, these cabinets can be arranged in substantially the same position on the inside and outside of the cabinet with the mounting wall as a boundary. For this,
It is possible to easily determine the mounting positions of these indoor and outer cabinets.

Furthermore, since the outdoor unit and the indoor unit are integrally provided in the outdoor cabinet, the outdoor unit and the outdoor unit are separated from each other, and the outdoor unit and the indoor unit are separately provided. The cabinet is easy to install.

Then, the damper is opened to allow the outside and the inside of the room to communicate with each other through the communication hole, and only the indoor fan is operated, while the operation of the compressor and the outdoor fan is stopped. Fresh air can be taken into the room from outside through the room, the duct, and the indoor cabinet. Further, by opening the damper and operating only the outdoor fan to stop the operation of the compressor and the indoor fan, indoor air is taken into the outdoor through the indoor portion of the indoor cabinet, the duct, and the outdoor cabinet. It can be exhausted from outside to outside. Thereby, room air can be ventilated.

The invention according to claim 2 is the air conditioner according to claim 1, wherein the compressor is a helical blade type compressor.

According to the present invention, since the compressor is a helical blade type compressor having a small size, light weight, ultra-quietness and low vibration, it is possible to reduce the size and weight of the air conditioner, to achieve ultra-quietness and low vibration.

According to a third aspect of the present invention, in the indoor cabinet,
3. The air conditioner according to claim 1, wherein an air filter for purifying ventilation is provided in the suction grill.

According to the present invention, the indoor air sucked into the suction grill of the indoor cabinet is purified by the air filter, and then flows into the indoor portion of the outdoor cabinet.
Heat is exchanged by the indoor heat exchanger inside the room. The heat-exchanged air is blown as conditioned air by the indoor fan, and is blown back into the room from the blowout grill of the indoor cabinet. For this reason, it is possible to purify the conditioned air blown into the room.

The invention according to claim 4 is the air conditioner according to any one of claims 1 to 3, wherein the indoor fan is a cross flow fan and the outdoor fan is a multi-blade fan.

According to the present invention, since the indoor fan is a cross flow fan, the indoor air is drawn in from the front,
The suction air can be blown forward at a slightly different angle. In addition, since the outdoor fan is a multi-blade fan (sirocco fan), while taking in outside air from the front,
Since it is possible to blow the outside air in a direction substantially perpendicular to the suction direction, it is possible to reduce the thickness in the direction along the vertical direction outward from the outer surface of the mounting wall of the outdoor cabinet accommodating both fans. be able to.

And an elastic blade that partitions the working chamber into a plurality of working chambers along the axial direction of the cylinder. However, the compressor 3 may be a rotary type or a reciprocating type.

In the refrigeration cycle configured as described above, by switching operation of the four-way valve 4, the refrigerant is supplied from the compressor 3 → the four-way valve 4 → the outdoor heat exchanger 6 → the expansion valve 7 → the indoor heat as shown by the solid arrow in the drawing. The cooling operation is performed by circulating the heat in the order of the exchanger 9 → the four-way valve 4 → the compressor 3. On the contrary, as shown in the broken line direction in the drawing, the compressor 3 → the four-way valve 4 → the indoor heat exchanger 9 → the expansion valve Heating operation is performed by circulating in the order of 7 → outdoor heat exchanger 6 → four-way valve 4 → compressor 3.

Then, as shown in FIG.
Is an outdoor cabinet 11 attached to the exterior outside surface of the mounting wall 2 such as a side wall of a lavatory, and an indoor cabinet 12 attached to the interior surface of the mounting wall 2 on the indoor side.
And the indoor cabinet 12 and the outdoor cabinet 11
And a straight duct 13 that connects the two so that they can communicate with each other.

As shown in FIG. 3, the outdoor cabinet 11
Has a thin rectangular box shape attached to the outer surface of the mounting wall 2, and the interior of the outdoor cabinet 11 is partitioned into an upper indoor portion 15 and a lower outdoor portion 16 by a partition wall 14, as shown in FIG. The outside 16 has an outside air inlet 17 formed on the front surface (left side in FIG. 1) of the outdoor cabinet 11, and an outside air outlet 18 formed continuously with the outside air inlet 17 on its lower bottom surface.

The outdoor unit 16 includes an outdoor heat exchanger 6 provided on the side of the outside air inlet 17 and a sirocco fan (multiple fan) which is an internal fan provided inside (to the right in FIG. 1). Wing fan) 5 and a helical blade type compressor 3 of a vertical type. Further, although not shown in FIG. 1, the outside 16 contains the four-way valve 4, the expansion valve 7, and a control device (not shown).

On the other hand, the interior portion 15 has an opening 19 having a predetermined diameter which opens upward in FIG. 1 from the partition wall 14 on the back surface of the mounting wall 2 side (the right side in FIG. 1). A cylindrical duct 13 is concentrically and integrally or integrally connected to the portion 19. The opening 19 and the inside of the duct 13 are vertically divided (or left and right) into two by a partition plate 20. , A suction passage 21 is formed, and a blow-out passage 22 is formed at a lower portion.

The indoor unit 15 has an indoor heat exchanger 9 disposed on the outlet side of the suction passage 21 and a cross flow fan 8 on the downstream side.
Are arranged horizontally. Below the indoor heat exchanger 9, a drain plate 9a for receiving drain dripping from the outer surface of the indoor heat exchanger 9 is disposed. The drain in the drain plate 9a is naturally drained by a drain pipe (not shown). Alternatively, the water is forcibly drained by a drain pump (not shown).

A communication hole 23 having a predetermined diameter is formed in the partition wall 14a for partitioning the indoor unit 15 from the outdoor unit 16 at the downstream side of the cross flow fan 8 to allow the indoor and external units 15 and 16 to communicate with each other. On the other hand, a damper 24 for opening and closing the communication hole 23 is provided, and the opening and closing of the damper 24 is controlled by a control device (not shown).

On the other hand, the duct 13 is
A rectangular plate-shaped main body 25 of the indoor cabinet 12 is attached to an opening end (the right end in FIG. 1) through which a is inserted and slightly protrudes toward the indoor side.

As shown in FIG.
In the center of the main body 25, a circular ventilation hole 25a having substantially the same shape and the same diameter or large diameter as the opening of the duct 13 is formed. The ventilation hole 25a is divided by a ventilation partition 26 into a semicircular suction grill 27 in the upper half in FIG. 4 and a semicircular outlet grill 28 in the lower half. An air filter 29 is provided on the suction grill 27.

At the front of the indoor cabinet body 25, an arcuate plate-shaped guide plate 30 which is slightly convex outward and curves is provided at a predetermined interval. The guide plate 30 includes a ventilation partition plate 26 protruding forward (to the right in FIG. 1) of the indoor cabinet main body 25, and a plurality of small columns 31, 31 erected on the outer peripheral portion of the indoor cabinet main body 25. , And guides the inflow of room air indicated by the solid line arrow in the figure and the blowout of conditioned air indicated by the dashed-dotted arrow in the lateral direction, so that the conditioned air is not directly blown forward in the room. I have to.

As shown in FIG. 5, an operation section 32 for operating the air conditioner 1 and a display section 33 for displaying the operation state and the like are provided at the upper end of the indoor cabinet body 25. I have.

Therefore, when, for example, the cooling operation of the air conditioner 1 is selected by operating the operation section 32, the damper 24 is closed, the compressor 3, the cross flow fan 8, and the sirocco fan 5 are operated, respectively, and the four-way valve 4 is operated. Is switched to the cooling mode side. For this reason, as shown in FIG. 2, the refrigerant compressed by the compressor 3 circulates in the direction of the solid line arrow in the figure, so that the refrigerant performs an evaporating action in the indoor heat exchanger 9 to absorb heat from the surrounding air and cool it.

On the other hand, as shown in FIG. 1, indoor air in a washroom or the like is drawn into the interior of the indoor cabinet 12 from the suction grill 27 by the cross flow fan 8, and is purified by the air filter 29 at that time. The air passes through the indoor heat exchanger 9 during the evaporating operation of the indoor unit 15 through the suction passage 21 in the duct 13, and is cooled down to cool air at that time. The air is blown out from the 12 blow-out grills 28 to the guide plate 30, where it collides with the inner surface, is guided in the lateral direction, and is blown out into the room. By repeating this, the room such as the washroom is cooled.

At this time, in the outdoor unit 16, the sirocco fan 5 sucks the external air into the outdoor unit 16 from the external air suction port 17, and when the external air passes through the outdoor heat exchanger 6 during the condensation operation, the outdoor unit 16 The heat radiation of the heat exchanger 6 is promoted, and thereafter the air is blown out again from the outside air outlet 18. By repeating this, the outdoor heat exchanger 6 exchanges heat.

On the other hand, when, for example, the heating operation of the air conditioner 1 is selected by operating the operation unit 32, the damper 24 is closed, the compressor 3, the cross flow fan 8, and the sirocco fan 5 are operated, and the four-way valve 4 is operated. Is switched to the heating mode side. For this reason, as shown in FIG. 2, the refrigerant compressed by the compressor 3 circulates in the direction of the solid line arrow in the figure, so that the refrigerant performs a condensing action in the indoor heat exchanger 9 and radiates heat to the surrounding air to be heated.

Then, as shown in FIG. 1, the indoor air in the washroom or the like is drawn into the interior of the indoor cabinet 12 from the suction grill 27 by the cross flow fan 8, and is purified by the air filter 29 at that time. After passing through the indoor heat exchanger 9 during the condensing action of the indoor part 15 through the suction passage 21 in the duct 13, the air is heated and warmed at that time, and then the indoor heat exchanger 9 is blown through the outlet passage 22 in the duct 13. The air is blown out from the blowout grill 28 of the cabinet 12 to the guide plate 30, where it collides with the inner surface, is guided in the lateral direction, and is blown out into the room. By repeating this, the room such as the washroom is heated.

At this time, in the outdoor unit 16, the sirocco fan 5 sucks outside air from the outside air suction port 17 into the outside unit 16, and when the outside air passes through the outdoor heat exchanger 6 during the evaporating operation, the outside air is removed. Heat absorption of the heat exchanger 6 is promoted, and thereafter, the heat is blown out again from the outside air outlet 18. By repeating this, the outdoor heat exchanger 6 exchanges heat.

When the ventilation operation is selected by operating the operation unit 32, the damper 24 is first opened to exhaust the room air to the outside, and the room 15 and the room outside 16 communicate with each other through the communication hole 23. .

At this time, the compressor 3 and the cross flow fan 8
Is stopped, while the sirocco fan 5 is operated, so that the inside of the exterior 16 where the sirocco fan 5 is located has a lower pressure than the interior of the room 15. For this reason, the indoor air is sucked into the exterior 16 through the duct 13 and the interior 15, and is exhausted from the outside air outlet 18 of the exterior 16. That is, the dirty air in the room is exhausted to the outside.

Next, while the damper 24 is still open, the compressor 3 and the sirocco fan 5 are stopped, while the cross flow fan 8 is operated. The pressure becomes lower than that in the outside 16. For this reason, outside air is sucked into the interior part 15 through the exterior part 16, and is blown into the room from the outlet grill 28 of the interior cabinet 12 through the duct 13. Thereby, fresh outside air is taken into the room and is ventilated. However, the order of exhausting the room air to the outside and taking the outside air into the room may be reversed.

Therefore, according to this air conditioner 1,
The air conditioning operation can be performed by closing the damper 24 and operating the cross flow fan 8, the sirocco fan 5, and the compressor 3, which are indoor and outdoor fans. Thus, the air-conditioned space can be comfortably air-conditioned. The indoor cabinet 12 is mainly composed of an indoor cabinet body 25.
In addition, since the intake grill 27 and the outlet grill 28 have an extremely simple configuration with only openings, the size, thickness, and weight of the indoor cabinet 12 can be reduced.

Therefore, the space for installing the indoor cabinet 12 in the room can be largely saved, and the amount of protrusion into the room can be reduced.
For this reason, the indoor cabinet 12 can be mounted in a relatively small non-room space such as a washroom or a toilet with a small space.

The duct 13 is provided in the indoor cabinet 1.
Since only the suction grill 27 and the outlet grill 28 need only be separately communicated with the indoor suction port and the indoor air outlet of the indoor unit 15 of the outdoor cabinet 11, respectively, the duct 13
Can be reduced in length. For this reason, the pressure loss due to the duct 13 can be reduced. Also,
Since the diameter of the opening of the duct 13 can be reduced, the diameter of the through hole 2a of the mounting wall 2 such as a side wall of a washroom or the like through which the duct 13 is inserted can also be reduced.

Further, in the outdoor cabinet 11,
Since the outdoor unit 16 and the indoor unit 15 are provided integrally, the installation of the outdoor cabinet 11 is easier than when the indoor unit and the outside units 15 and 16 are separately configured and installed.

Then, the damper 24 is opened and the communication hole 23 is opened.
The outside 16 and the inside 15 are communicated with each other, and only the cross flow fan 8 is operated, while the operation of the compressor 3 and the sirocco fan 5 is stopped.
Fresh outside air can be taken into the room from the room cabinet 12 through the room portion 15 and the duct 13. Further, by opening the damper 24 and operating only the sirocco fan 5 and stopping the operations of the compressor 3 and the cross flow fan 8, the room air is taken into the outside 16 through the room cabinet 12, the duct 13 and the room 15. Further, air can be exhausted from the outside 16 to the outside. That is, indoor air can be ventilated.

Also, since the compressor is a helical blade type compressor 3 of small size, light weight, super quiet and low vibration,
It is possible to reduce the size and weight of the air conditioner 1, to achieve ultra-low noise and low vibration, and to transmit the vibration of the compressor even when the air conditioner 1 is mounted on a mounting wall.

Further, the indoor air sucked into the suction grill 27 of the indoor cabinet 12 is purified by the air filter 29,
And heat is exchanged by the indoor heat exchanger 9 in the indoor part 15. The heat-exchanged air is blown as conditioned air by the cross flow fan 8, and is blown into the room again from the blowout grill 28 of the indoor cabinet 12. For this,
It is possible to purify the conditioned air blown into the room.

Since the indoor fan is the cross flow fan 8, it is possible to suck indoor air from the front of the indoor cabinet 12 and blow the sucked air forward at a slightly different angle. Further, since the outdoor fan is a multi-blade fan (sirocco fan) 5, it is possible to suck outside air from the front and to blow out the suction air in a direction substantially perpendicular to the suction direction. 5 can be made thinner in the direction along the outside in the vertical direction from the outer surface of the mounting wall 2 of the outdoor cabinet 11 that houses the cabinet 5.

[0051]

As described above, according to the present invention, the air conditioning operation can be performed by closing the damper and operating the indoor fan, the outdoor fan, and the compressor. Thus, the air-conditioned space can be comfortably air-conditioned. In addition, since the indoor cabinet has an extremely simple configuration in which only the inlet grill and the outlet grill are opened,
The size, thickness, and weight of the indoor cabinet can be reduced.

Therefore, the space for mounting the indoor cabinet mounting wall on the indoor side can be greatly reduced, and the amount of protrusion of the indoor cabinet mounting wall into the room can be reduced. For this reason, the indoor cabinet can be mounted in a relatively small non-room space such as a washroom or a toilet with a small space.

The duct is straight and penetrates the mounting wall of both the indoor and outside cabinets straight in the thickness direction, and connects the suction grill and the blow grill of the indoor cabinet to the interior of the indoor cabinet. Since the suction port and the indoor outlet are respectively connected to each other, the duct and the outdoor cabinet can be integrated, and the length of the duct can be reduced. For this reason, the pressure loss due to the duct can be reduced. Further, since the diameter of the opening of the duct can be reduced, the diameter of the through hole of the mounting wall for allowing the duct to pass therethrough can also be reduced.

Further, since the outdoor unit and the indoor unit are integrally provided in the outdoor cabinet, the outdoor unit and the outdoor unit are separated from each other, and the outdoor unit and the indoor unit are separately constructed. The cabinet is easy to install.

Then, the damper is opened to communicate the outside of the room with the inside of the room through the communication hole, and only the indoor fan is operated, while the operation of the compressor and the outdoor fan is stopped, so that the outside of the room and the inside of the room are stopped. And fresh air can be taken into the room from the indoor cabinet through the duct. Further, by opening the damper and operating only the outdoor fan to stop the operation of the compressor and the indoor fan, the indoor air is taken into the outdoor through the indoor cabinet, the duct and the indoor part, and further from the outdoor. Can be exhausted to the outside. That is, indoor air can be ventilated.
