Description

[Detailed description of the invention] (Field of industrial application) This invention is a multifunctional device that allows you to select from three types of operation: cooling, dehumidification, and ventilation, simply by switching the heating/cooling operation to stop and switching the damper device. Regarding air conditioners for cooling, dehumidification, and ventilation.

(Prior technology) There have been small air conditioners for home use that can perform heat pump dehumidification.For example, "Bathroom dryer for effective use of bathroom space"
Published by Heat Pump Study Group (Heat Pumps and Their Applications, Vol. 14, pp. 67-68) on November 1st.

As shown in FIGS. 2 and 3, the air conditioner described in the above document has a cooler 7, a heater 6, and a fan installed from the windward side in a casing 1 having an inlet 11, an outlet 23, and an exhaust outlet 24. 25, which is placed on the ceiling of the bathroom so that the suction port 11 and the air outlet 23 face the bathroom, and the exhaust port 24 is connected to the exhaust duct 26 for use.

(Problem to be solved by the invention) Although this air conditioner is a dehumidifying-only type and cannot perform cooling operation, by adding conventionally known technology, the heater 6 can be used as a condenser when necessary. At the same time, although it is possible to create a structure that allows air passing through the condenser and air passing through the cooler to flow through separate passages to perform cooling operation, it is not possible to perform both cooling and dehumidification operations. It is necessary to prevent conditioned air from escaping through the exhaust port 24, and therefore this air conditioner is usually fitted with a vent cap 27 at the outlet end of the exhaust duct 26 to close the port.

However, even if it is desired to ventilate the room using the air conditioner, it is necessary to remove the vent cap 27 at a remote location, resulting in poor work efficiency.

Furthermore, even if ventilation can be performed by removing the vent cap 27, most of the air flows back into the room from the outlet 23 and does not flow toward the exhaust duct 26 because the flow resistance to the wind is smaller at the outlet 23. Therefore, ventilation operation cannot be performed substantially at the air outlet 2.
It is also necessary to take some measures on the third side, and it should be said that it is difficult to realize an air conditioner that can effectively perform cooling, dehumidification, and ventilation from such known examples.

In order to address these problems, the present invention has a simple and compact structure, and has excellent operability.It meets the requirements as a general-purpose device, and can also be used for cooling, cooling, etc.
The purpose of the present invention is to provide an air conditioner that can reliably perform dehumidification and ventilation operations with high efficiency.

(Means for Solving the Problems) Therefore, as is clear from the attached drawings related to the embodiment, the present invention aims to direct air from the heater 6 to the first outlet 12.
a second air passage 3 whose suction port 11 is shared with the first air passage 2 and which causes air to be sent from the cooler 7 to the second air outlet 13;
An inlet 14 is provided at a windward position facing the first outlet 12 in the air passage 2 , and an inlet 14 is provided at the upwind position facing the first outlet 12 in the air passage 2 .
A third air passage 4 having an outlet 15 opened at a windward position facing the outlet 13 is provided in the casing 1, and a first outlet 12 and an inlet 14 are provided in the casing 1.
A damper device 5 is provided which can switch between opening and closing to perform heating and blowing operation of the first air passage 2 and cooling and blowing operation of the second air passage 3. 12 or the inlet 14 to perform dehumidification or cooling, while the first
By causing only the blowing operation of the air passage 2 and closing the inlet 14 by the damper device 5,
It is characterized by being able to provide ventilation.

Further, in the invention of claim 2, the suction port 11 and the second blowout port 13 are opened at the bottom surface of the casing 1, and the first blowout port 12 is opened at an outer surface other than the bottom surface, and the suction port 11 , the second outlet 13 faces the area to be air-conditioned, and the first outlet 12 faces outside the area to be air-conditioned, and is installed on the ceiling.

(Function) The first to third air passages 2, 3, and 4 are provided, and a damper device 5 is provided that can switch between opening and closing the first air outlet 12 used as an exhaust port and the inlet 14 that guides warm air. As a result, three types of operation, namely cooling, dehumidification, and ventilation, are possible by switching the damper device 5, selecting and controlling heating, cooling operation/stop, and ventilation operation, and this operation is also applicable to air conditioning. This can be easily done only on the side closest to the machine setting location.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a ceiling-mounted air conditioner according to claim 2, in which an inlet 11 and a second outlet 13 are opened at the bottom of the casing 1 and spaced apart from each other. The first air outlet 12 is opened and the duct connection flange 1 is connected to the air outlet 12.
6 is attached.

Inside the casing 1, an introduction chamber 17 facing the suction port 11, a first air passage 2 and a second air passage 3 communicating with the introduction chamber 17, and associated with both passages 2, 3 are provided. a third air passage 4;
A machine room 18 is provided, and the first air passage 2 has the first air outlet 12 at its downstream end, while the second air passage 3 is connected to the first air passage 2 through an insulating partition 21. It is disposed parallel to the air flow and has a second air outlet 13 at the downstream end.

Next, the third air passage 4 is connected to the first air passage 2.
For example, the partition 2 at the windward position facing the air outlet 12
The inlet 14 is opened at a position close to the first air outlet 12 of the first air passage 1, while the outlet 15 is opened at a windward position facing the second air outlet 13 in the second air passage 3, for example, directly above the second air outlet 13. In the example shown in FIG. 1,
The third air passage 4 is simply formed by extending a wall plate 22 vertically up to a position immediately in front of the second air outlet 13 provided at the bottom.

Inside the first air passage 2, a heater 6, for example, a condenser in a heat pump cycle, and a fan 9 for the condenser are housed from the windward side.On the other hand, inside the first air passage 3, an air A cooler 7, such as an evaporator, and a fan 10 for the evaporator are housed in the machine room 18 from above, and refrigeration equipment such as a compressor 8 is housed in the machine room 18.

In FIG. 1, numeral 19 indicates an air filter disposed in the suction port 11, and numeral 20 indicates a drain pan disposed at the lower part of the evaporator 7.

In the air conditioner having the structure described above, a damper device 5 is provided in association with the first outlet 12 and the inlet 14, so that both the ports 12 and 14 can be switched to open and close. For example,
Both ports 12, 14 are separated by a rotation angle of about 90°.
A valve plate made of a flat plate is disposed via a hinge so as to be rotatable in the forward and reverse directions through 90°, and a connected lever (not shown) can be operated manually or electrically.

Next, the mode of operation of this air conditioner will be explained. In the cooling operation, the refrigeration system is operated to perform heating operation of the condenser 6 and cooling operation of the evaporator 7, and at the same time, the air blowing by the above-mentioned fans 9 and 10 is performed. Let it happen.

At the same time, the damper device 5 is operated to close the inlet port 14, which is indicated by a broken line in FIG.

In this way, a portion of the indoor air, for example indoor air, introduced from the suction port 11 flows into the first air passage 2, exchanges heat with the condenser 6, becomes warm air, passes through the first air outlet 12, and is discharged into the air. It flows into the exhaust duct connected to the outlet 12 and is exhausted outside.

On the other hand, the remaining amount of indoor air introduced from the suction port 11 flows into the second air passage 3, exchanges heat with the evaporator 7, becomes cold air, and is sent into the living room from the second outlet 13. Cooling operation is performed.

In this case, it goes without saying that forced ventilation is performed in an amount commensurate with the amount of air discharged through the first air passage 2.

On the other hand, in the dehumidifying operation, the damper device 5 is operated to close the first air outlet 12 as shown by the solid line while performing the heating operation and the cooling operation.

The dynamics of the cold air blown into the room from the second air outlet 13 through the second air passage 3 is the same as during cooling operation, but on the other hand, the warm air that has passed through the first air passage 2 is blown out from the inlet 14. It reaches the third air passage 4 and the outlet 1
5, but in that case, the hot air and the cold air in the second air passage 3 mix just before reaching the second air outlet 13, resulting in air whose temperature is slightly higher than that of the intake air, which blows into the room. will be sent to.

In this way, the evaporator 7 dehumidifies the moisture contained in the air during cooling, and as a result, the dehumidifying operation continues.

Next, regarding the ventilation operation, the operation of the refrigeration system and the evaporator fan 10 is stopped, and the operation of the condenser fan 9 is stopped.
At the same time, the damper device 5 is operated at the inlet 1.
4 Operate to the closing side.

In this way, the entire amount of indoor air sucked in from the suction port 11 passes through the first air passage 2 and is sent out from the first outlet 12 to the outside, and as a result, an amount of outside air commensurate with this amount of air is introduced into the room, resulting in ventilation. It will be done.

In this way, the three types of operation, cooling, dehumidifying, and ventilation, can be selected in the air-conditioned area by turning on/off the refrigeration system and the fans 9, 10, and switching the damper device 5.

This air conditioner can also perform spot cooling by connecting a duct to the second outlet 13, so it can be used in the washroom,
Installed in a unit that combines a bathtub and toilet,
This is a suitable facility that only needs to provide air conditioning for the toilet and washroom, and dehumidify for drying laundry.

(Effect of the invention) The third air passage 4 is provided in relation to the first air passage 2 through which warm air flows and the second air passage 3 through which cold air flows, and the inlet 14 of the third air passage 4 and the first
By providing a damper device 5 that switches between opening and closing the first outlet 12 of the air passage 2, three types of cooling, dehumidification, and ventilation can be achieved by simply operating the damper and starting and stopping heating and cooling operations at the demand site. A simple air conditioner that can achieve air conditioning and has multiple functions can be provided at low cost.

In addition, in claim 2, it is suitable for a simple ceiling-mounted type, is easy to combine with a bathroom unit, etc., and can be applied to a popular type for home use, and has a wide range of uses.
