Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner which uses a ventilation means for discharging indoor air to the outside for discharging exhaust heat.

[0002]

2. Description of the Related Art Generally, household air conditioners are roughly classified into an integrated type that is installed on a window or the like and directly exhausts to the outside, and a separated type that is separated into an indoor unit and an outdoor unit.

[0003]

By the way, in recent years, users' demands for local heating and cooling in kitchens, toilets, dressing rooms, washrooms, etc. have been increasing.

The places where local cooling and heating as described above are required,
Since it is located in a recessed position indoors and there is no window suitable for installing an integrated air conditioner, in most cases, the separation air conditioner has to be selected.

However, when the separation type air conditioner is adopted, the piping work for connecting the indoor unit and the outdoor unit and the piping work for draining the drain water generated in the indoor unit are required, resulting in an increase in the number of steps. As a result, the problem of high cost arises.

The present invention has been made in view of the above points, and an object of the present invention is to enable local cooling and heating at low cost by utilizing the existing ventilation means for exhaust heat of the air conditioning means. It is a thing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

First Embodiment FIGS. 1 to 3 show an air conditioner according to a first embodiment of the present invention.

This air conditioner is, as shown in FIG.
Ventilation installed in the upper part of the system kitchen 1 of the kitchen, adjacent to the hanging cabinet 2 installed above the system kitchen 1 and above the gas stove 3 in the system kitchen 1. It is composed of a range hood 4 which is a means, and an integrated air conditioning means 5 which is attached to the lower surface of the hanging cabinet 2 at a position adjacent to the suction port 4a of the range hood 4. Reference numeral 6 is a sink in the system kitchen 1.

The range hood 4 exhausts smoke and the like generated during cooking by the gas stove 3 to the outside.
A ventilation fan 20 is built in.

As shown in FIGS. 2 and 3, the air conditioning means 5 has an indoor air suction port 8 located on one side of the lower surface (that is, the side opposite to the range hood 4) and an opposite side of the indoor air suction port 8. Side (that is, the side of the range hood) for exhausting heat 9
And a conditioned air outlet 10 located in the central portion of the lower surface.
An air flow passage 11 extending from the indoor air suction port 8 to the exhaust heat air outlet 9 and the conditioned air air outlet 10 and a machine chamber 12 partitioned from the air flow passage 11 are formed and arranged in the machine chamber 12. Compressor 13 and the exhaust heat outlet 9
The heat source side heat exchanger 14 located inside, the heat exhaustion fan 15 located between the heat source side heat exchanger 14 and the exhaust heat outlet 9, and the inside of the conditioned air outlet 10. The use-side heat exchanger 16 located in the above position and the conditioned air blowing fan 17 located between the use-side heat exchanger 16 and the conditioned air outlet 10 are built in. In the present embodiment, a cross flow fan is used as the exhaust heat fan 15.
A sirocco fan (trade name) is used as the conditioned air blowing fan 17. Reference numeral 18 is an oil catch net that is attached to the indoor air intake port 8 so as to be replaceable, and 19 is a bellows-like blowing duct for blowing conditioned air that is connected to the conditioned air outlet 10.

The air conditioner 5 causes the heat source side heat exchanger 14 to act as a condenser and the utilization side heat exchanger 16 to act as an evaporator during the cooling operation, while the heat source side heat exchanger 14 operates during the heating operation. The use-side heat exchanger 16 is made to act as an evaporator and the condenser is used as a condenser, and cooling / heating operation is enabled.

With the above construction, when the range hood 4 and the air conditioner 5 are operated during cooking work around the system kitchen 1 in the summer or winter, the air is sucked from the indoor air intake port 8. The indoor air W ₁ is cooled or heated when passing through the use-side heat exchanger 16 to be conditioned air W ₂ and conditioned air outlet 1
No. 0 and the blowing duct 19 are blown to a limited cooking work area to perform local cooling or heating, while passing through the heat source side heat exchanger 14, exhaust heat (that is, cold heat).
Is exhausted from the exhaust heat outlet 9 as exhaust W ₃ , and is discharged to the outside through the range hood 4.

The drain generated in the heat exchanger 16 on the utilization side during the cooling operation is received by a drain pan (not shown) and exchanges heat with the high-temperature refrigerant flowing to the heat exchanger 14 on the heat source side which acts as a condenser in the drain pan. By doing so, it is supposed to be evaporated.

As described above, according to the invention of the present application, even in a kitchen located at a deep position indoors without a window or the like on which an air conditioner can be installed, exhaust heat is exhausted through the range hood 4, which is an existing device. Since it is possible to exhaust the air, it is possible to use the integrated air conditioning means 5 that does not require a refrigerant pipe, a drain pipe, etc., and it is possible to satisfy the user's demand for local heating and cooling in the kitchen at low cost. Of.

The air conditioner of the present invention can be installed not only in the kitchen in the present embodiment but also in a toilet, washroom, dressing room, etc. where ventilation means is already installed.

Second Embodiment FIGS. 4 and 5 show an air conditioner according to a second embodiment of the present invention.

In this case, the indoor air suction port 8 of the air conditioning means 5 is formed in the central portion of the lower surface of the casing 7, and the conditioned air outlet 10 is formed on one side of the casing 7 (that is, on the side opposite the range hood). The air flow passage 11 extends from the indoor air inlet 8 to the conditioned air outlet 10 side and the exhaust heat outlet 9
It is branched to. The conditioned air blowing fan 17 is a cross flow fan. The other configuration and operation and effect are the same as those of the first embodiment, and the description is omitted.

Third Embodiment FIG. 6 shows an air conditioner according to a third embodiment of the present invention.

In this case, the casing 7 of the air conditioning means 5
Has a rectangular parallelepiped shape and is arranged in the hanging cabinet 2. The exhaust heat outlet 9 of the air conditioner 5 is connected to the suction side of the ventilation fan 20 in the range hood 4 via a duct 21. Further, the conditioned air outlet 10 of the air conditioning means 5 is the system kitchen 1
Is connected to a blowout port 22 provided on the lower surface of the hanging cabinet 2 above the sink 6 via a connection duct 23. Reference numeral 24 is a casing of the ventilation means 4. With this configuration, the exhaust heat from the air conditioning unit 5 is surely exhausted to the suction side of the range hood 4 via the duct 21, and there is an advantage that the exhaust heat exhaust is ensured. The other configuration and operation and effect are the same as those of the first embodiment, and the description is omitted.

Fourth Embodiment FIG. 7 shows an air conditioner according to a fourth embodiment of the present invention.

This air conditioner is used by being installed on the inner wall 25 of the toilet, and the ventilation means 4 and the air conditioning means 5 are integrally formed.

That is, the heat source side heat exchanger 14 in the air conditioning means 5 is arranged on the suction side of the ventilation fan 4 acting as ventilation means, and the casing 7 and the casing 24 of the ventilation fan 4 are integrated. Reference numeral 25 is an exhaust duct.
