Description

[Detailed explanation of the idea] The present invention relates to an air conditioner.

In conventional air conditioners, many shielding plates are placed at right angles to the flow of air at the entrance of the mixing chamber to create a uniform mixed air while changing the wind direction. However, with this method, the shielding plates create a large ventilation resistance. This has the disadvantage that the amount of air blown decreases.

The present invention eliminates the above drawbacks, and in order to obtain uniform mixed air without increasing ventilation resistance, the two intersecting air inlets of the mixing chamber are made into a grill structure, and the two grill surfaces intersect. To provide an air conditioner in which the width of the grille is wide on the side near the line and narrow on the side far from the line.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a cross-sectional plan view of an embodiment of the air conditioner according to the present invention, and FIG. 2 shows a partially cutaway perspective view thereof.

A cooling heat exchanger, ie, an evaporator 4, and a heating heat exchanger, ie, a heater 7, are arranged vertically, and the air sucked in through the suction port 1 is passed through a proa fan 3 connected to a motor 2.
After being blown by the evaporator 4 and cooled by the evaporator 4,
The temperature is distributed 1+ in two directions by the two temperature control valves 5 and 6.

A portion of the cold air is directly introduced into the mixing chamber 8 through a grill 9 formed at the inlet opposite the evaporator 4,
The other part is heated appropriately through the heater 7 and introduced into the mixing chamber 8 as warm air through the grill 10 formed at the entrance opposite the heater 7.

In this way, in the reheat air mix type air conditioner, the purpose is to dehumidify the intake air through the evaporator 4, so in order to cool the air more than necessary, a part of it is heated by the heater 7 and sent to the mixing chamber 8. I am trying to mix the two.

The mixing ratio of cold air and warm air introduced into the mixing chamber 8 is appropriately adjusted according to the opening degrees of the two temperature control valves 5 and 6.

The surfaces of the grilles 9 and 10, which are the entrances to the mixing chamber 8, face the mixing chamber 8 at right angles as shown in the figure, or at any arbitrary angle where the surfaces intersect with each other. The cold air and warm air are mixed in the mixing chamber 8.

Each of the grills 9 and 10 includes a plurality of vertical loopers 11 disposed parallel to the wind path, and a plurality of horizontal loopers 12 individually disposed between the vertical loopers 11 parallel to the wind path. Consisting of

The intervals between the vertical loopers 11 are not uniform, and the two grills 9
, 10 intersect with each other, the distance WL between the vertical loopers 11 is the widest, and the distance WL between the vertical loopers 11 is the widest, and the distance between the vertical loopers 11 is gradually narrowed as the distance from this distance increases.
The distance W5 between the vertical loopers 11 on the sides of the side plates 13 and 14 of the device
is formed the narrowest.

Generally, cold air and warm air are fed through two grills 9, which are their entrances.
Mixing is easy at the position where the 10 planes intersect with each other, and it is difficult to mix at positions further apart.

Utilizing this property, as mentioned above, the interval between the vertical louvers 11, that is, the width of the grille, is widened on the side where the face grille surfaces intersect to reduce air resistance and cool air flows in this area.
The amount of warm air passing through is increased, and the area away from the intersection is narrowed to increase air resistance and reduce the amount of air passing through this area.

As a result, mixing is well performed in the mixing chamber 8 as a whole, and the temperature is made uniform.

An air outlet 16 is provided in a corner of the floor 15 of the mixing chamber 8 that is far from both grills 9 and 10.
Blow air that is well mixed and has a uniform temperature is sent in.

In the above embodiment, the width of the vertical louvers 11 of the grills 9 and 10 is changed, but depending on the arrangement of the evaporator 4 and heater 7, the spacing between the corresponding louvers may be changed.

As mentioned above, according to the air conditioner according to the present invention, the mesh width of the grilles provided at the two entrances of the mixing chamber is widened at the position where the two grill surfaces intersect, and narrowed at the opposite side. It has the feature of minimizing ventilation resistance and creating mixed air at a uniform temperature within the mixing chamber.
