Description

[Detailed Description of the Invention] The present invention relates to a simple air conditioner capable of dehumidifying operation.

Various air conditioners have been proposed in the past, but when performing dehumidification operation in a conventional air conditioner capable of dehumidification, an evaporator installed in the ventilation path cools the indoor air and also dehumidifies it. The method was to heat the cooled air to an appropriate temperature using an electric heater, or to mix warm air generated by a condenser with cold air to raise the temperature to an appropriate temperature.

However, when dehumidifying conventional air conditioners capable of dehumidifying, especially air conditioners that mix hot air generated by a condenser with cold air, the cold air and hot air do not mix well, and the cold air and hot air alternate. Sometimes I would break out.

Therefore, especially in devices that perform local air conditioning, the temperature of the air outlet frequently changes between hot and cold, which may cause discomfort.

The present invention has been developed in view of the above points, and provides an air conditioner that can perform comfortable air conditioning by constantly mixing and stirring hot air and cold air even during dehumidifying operation. It is something.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The air conditioner of the present invention will be described in detail below with reference to the drawings showing embodiments of the present invention.

FIG. 5 is a perspective view of parts of the air conditioner.

In these drawings, reference numeral 1 denotes a cabinet having an indoor suction port 2 and a cold air outlet 3 formed on its front side, and a hot air outlet 4 and a hot air suction port 5 formed on its rear side.

The hot air outlet 4 provided on the rear side of the cabinet 1 is provided on one side of a plate-shaped body 6 bent at right angles as shown in FIG. By changing the direction of the balloon, the direction of the balloon can be changed upward or backward.

Inside the cabinet 1, a condenser 7 (installed facing the hot air suction port 5) and an evaporator 8 (installed facing the indoor suction port 2) constituting the refrigeration cycle are installed inside the cabinet 1. ), compressor 9, etc., cold air fan 10, hot air fan 11. A fan motor 12 that drives these fans
, a dew pan 1 for receiving drain water generated in the evaporator 7;
3. A drain tank 14 for storing drain water from the dew pan 13 is installed.

Further inside, there is a ventilation path A passing through the indoor suction port 2 → evaporator 8 → cold air fan 10 → cold air fan casing 15 → cold air outlet 4, and hot air suction port 5 → condenser 7 → hot air fan. A ventilation path B passing through 11→hot air fan casing 16→hot air outlet 4, and a ventilation path C branching from the hot air fan casing 16 of ventilation path B toward the cold air outlet 4 side are provided.

A damper 17 is provided at the branch point of the ventilation path B and the ventilation path C to selectively open and close these paths, and directs the hot air that has passed through the condenser 7 to either the cold air outlet 3 or the hot air outlet 4. is configured to selectively ventilate the area.

Further, a cold air guard 18 is interposed between the ventilation path A and the ventilation path C, so that the cold air and hot air that have passed through these paths A and C are mixed at the 3 portions of the cold air outlet.

That is, the condenser 7 and the evaporator 8 are arranged in separate ventilation passages, and the two passages are connected at their ends by switching the damper 17 during dehumidification operation.

Reference numeral 19 denotes a movable looper disposed on the connecting portion of the connected two-way air passages B and A, that is, on the ventilation passage A side in front of the cold air outlet 3. This movable looper 19 is a plate having a substantially S-shaped cross section. During operation, it is rotated by a driving means such as a motor (not shown).

20 is a filter provided at the 2 parts of the indoor suction port, 2
Reference numeral 1 denotes a drain switch which is switched on when it detects that the drain tank 14 is full of water, and 22 is a caster attached to the bottom of the cabinet l-1, and the caster 22 allows the main body to move.

The air conditioner according to the present invention is constructed as described above, and its operation is as follows.

First, during cooling operation, high-temperature, high-pressure refrigerant gas compressed by the compressor 9 is cooled and condensed by the condenser 7, and heat-sensitive and latent heat is removed from the air in the evaporator 8, and it becomes an evaporated gas body, which is sent to the compressor 9.
returns to form one cycle.

At this time, the air sucked in from the hot air suction port 5 is blown out from the hot air outlet 4 to the rear or above of the main body through the ventilation path B by the hot air fan 11.

On the other hand, the air sucked in by the indoor suction port 2 is cooled by the evaporator 8, passes through the ventilation path A, and is blown out from the cold air outlet 3 to cool the target area.

During this cooling, the cold air blown out from the cold air outlet 3 is blown out from the upper side to the lower side while constantly changing the wind direction by the rotation of the movable looper 19, so that the room can be cooled without any change.

In other words, this looper 19 has a swinging action that distributes the cold air upward and downward.

Drain water that is dehumidified when passing through the evaporator 8 is transferred to a dew pan 13.
The water is led to the drain tank 14 and stored therein, and when the weight reaches a certain level, the operation is stopped by the function of the drain switch 21.

Next, during dehumidification operation, the damper 17 is switched from the B side to the C side as shown by the broken line in FIG.

When switched in this way, the ventilation path C is blocked by the damper 17, and by passing through the condenser 7, the generated hot air passes through the ventilation path B, and then the ventilation path A,
It reaches the cold air outlet 3 which is the connection part B.

Here, the warm air that has passed through this ventilation route B is transferred to the ventilation route A.
The cool air is mixed with the cold air, and further, by the rotation of the movable looper 19 provided at the connecting part, the cold air is distributed over the top and bottom of the air outlet 3 and blown out compared to the hot air. The mixture is uniformly mixed and stirred and then blown out from the blower outlet 3.

In other words, cold air constantly moving upward and downward collides with warm air blown out from the air outlet 3, and the cold and hot air is agitated and mixed at the air outlet 3 by the collision of the cold air moving in this direction.

The blowout temperature is higher than the suction temperature drawn from the indoor suction port 2 portion by the amount of heat equivalent to the input consumed by the compressor 9, and the moisture is blown out when it passes through the evaporator 8 in the same way as during cooling operation. The water is dehumidified and stored in the drain tank 14 at the bottom.

FIGS. 4 and 5 show another embodiment of the present invention, in which a connecting cylindrical part 23 is provided around the hot air outlet 4 provided in the plate-like body 6, and this cylindrical part 23 has a Exhaust duct I
24 is connected to discharge hot air outdoors, or as shown by the broken line, a cylinder 25 is connected to discharge hot air to a high place indoors to reduce thermal effects during cooling.

As described above, the present invention provides an air conditioner that is integrally equipped with a condenser that generates hot air and an evaporator that generates cold air, in which the condenser and evaporator are arranged in separate ventilation paths, and the two-way air path is are connected at the ends, a damper is provided in the ventilation path in which the condenser is arranged to open and close the ventilation path, and a movable looper is provided on the cold air path side of the connecting portion of the two-way air path, which is rotated by the drive of a motor. This air conditioner is characterized by:

Therefore, by closing the ventilation path in which the condenser is disposed by the damper, the cold and hot air are blown out separately without merging.

In this case, when the temperature is high and cooling is required, the device can be used as a cooler by blowing only cold air into the room and exhausting warm air outside.Furthermore, the direction of the cold air can be constantly changed by the louver. speech bubble,
Cools the room evenly.

This change in the blowing direction of the louver is particularly effective in air conditioners that are integrated with a condenser and compressor, which often expose the human body to cold air.

On the other hand, if only warm air is blown indoors and cold air is exhausted outdoors, the device can also be used as a heater.

Next, when the damper is switched to open the air passage on the condenser side, the cold and hot air joins and mixes at the connecting portion of both air passages, and is blown into the room.

Therefore, the indoor air is dried and cooled by the dehumidifying and cooling action of the evaporator, and is raised to an appropriate temperature (for example, room temperature) by the combined warm air, allowing the device to be used as a dehumidifier.

In this case, the direction in which the cold air is blown is constantly changed by the louver, and the warm air joins the cold air moving in this direction, so that the cold and hot air is uniformly mixed and stirred before being blown out.

This is particularly effective in integrated air conditioners where the body is often exposed to dehumidified air directly.

As described above, according to the device of the present invention, cooling and dehumidification can be performed by switching the dampers, and the blown air is effectively blown out by the louvers as described above.
