Description

  The present invention relates to a wall-mounted air conditioner equipped with a ventilation device, and more particularly, does not affect the ventilation port that guides outdoor air to the suction port and the flow of indoor air sucked from the suction port. And a ventilation device having a ventilation duct provided with ventilation holes for distributing outdoor air to the suction port.

  In conventional air conditioner ventilators, outdoor air is taken into the indoor unit to keep the room air clean without opening a window for ventilation or turning a separate ventilation fan. An air filter, an indoor heat exchanger, a blower fan, etc. are provided in the air passage connecting the suction port at the top of the housing and the air outlet at the bottom of the housing, and attached to the indoor wall surface via an installation plate The indoor unit is provided with an intake duct that communicates from the outside of the wall surface to the front of the air filter, and is provided with a blower that sends outdoor air to the intake duct on the outside of the wall surface, and the outdoor air sent to the front of the air filter and the upper part of the housing A configuration has been disclosed in which indoor air sucked from the air inlet is sent out indoors by a blower fan through an air filter and an indoor heat exchanger (see, for example, Patent Document 1).

  However, in the ventilator for an air conditioner having the above-described configuration, the intake duct is arranged in front of the air filter in a state where it is branched into two flow paths. Since air resistance is generated when air is sucked, the suction efficiency when sucking indoor air is lowered.

  In addition, outdoor air is sent to the front of the air filter by a branched intake duct. However, outdoor air is concentrated locally facing the outlet of the intake duct, so that indoor heat exchange is performed. The balance of heat exchange by the vessel is lost, and the dust cannot be uniformly removed by the air filter, so that the maintainability is not good.

Japanese Patent Laid-Open No. 10-274424 (pages 1 to 4 and FIGS. 1 to 3)

  In view of the above-described problems, the present invention is provided so as not to affect the flow of indoor air sucked from the ventilation port and the intake port that guides outdoor air to the suction port, and distributes outdoor air to the suction port. It is an object of the present invention to provide a wall-mounted air conditioner to which a ventilation device including a ventilation duct having a ventilation hole is connected.

In order to solve the above-described problems, the present invention includes an air filter, a heat exchanger, and a blower fan in an air passage connecting a suction port provided with a suction grille and an outlet, and introduces outdoor air into the air passage. In an air conditioner equipped with a ventilation device,
The ventilator is provided so as not to affect the flow of indoor air that is communicated to the ventilation port and is sucked from the suction port, and the outdoor air is connected to the ventilation port. And a ventilation duct having ventilation holes for distributing the air.

  In addition, the ventilation duct is formed integrally with the suction grill.

  Furthermore, the ventilation holes are arranged so as to distribute outdoor air evenly toward the air filter.

  According to the present invention, the ventilation duct that introduces outdoor air into the suction port is configured so as not to affect the flow of the indoor air sucked from the suction port. Without increasing the air resistance of the air, it is introduced so that the outdoor air is evenly distributed to the air filter facing the suction port, and the balance of heat exchange is not lost by supplying it evenly to the heat exchanger. It becomes the air conditioner which did.

Embodiments of the present invention will be described below in detail as examples based on the accompanying drawings.
FIG. 1 is an explanatory view of an air conditioner according to the present invention, (A) is a sectional view, (B) is a sectional view of an essential part, FIG. 2 is an explanatory view of an air conditioner according to the present invention, and (A) is FIG. 3B is a top view of the suction grille as viewed from the top, FIG. 3B is a top view of the suction grille as viewed from the bottom, and FIG. 3 is an enlarged view of part A shown in FIG.

  The air conditioner according to the present invention, as shown in FIG. 1 as Example 1, has an air passage connecting an air inlet 2 provided with an intake grill 1 provided at an upper portion and an air outlet 3 provided at a lower portion. A filter 4, a heat exchanger 5, and a blower fan 6 are provided, and the indoor air sucked from the suction port 2 is heat-exchanged by the heat exchanger 5, and then blown out into the room from the blowout port 3. In addition to being harmonized, a ventilation device 10 that sucks outdoor air is provided so that ventilation can be performed.

  The ventilation device 5 includes a ventilation fan 6 for introducing outdoor air, and a ventilation air passage that is connected to the ventilation fan 6 and penetrates the outer wall surface to guide the outdoor air to the indoor side. The air inlet 4 is connected to a ventilation port 7 for guiding outdoor air upstream of the air filter 4 facing the suction port 2.

  A ventilation duct 9 having a plurality of ventilation holes 8 is communicated with the ventilation port 7 so as to face the air filter 4, so that outdoor air introduced by the ventilation fan 6 is transmitted to the air filter 6. 4 is distributed evenly and supplied to the heat exchanger 5 without any deviation, so that the balance of heat exchange is not lost.

  The ventilation duct 9 is disposed, for example, so as to extend along the vertical beam 1a and the horizontal beam 1b constituting the suction grill 1, and is provided so as not to affect the flow of room air sucked from the suction port 2. Thus, the air resistance of the room air sucked from the suction port 2 is not increased.

  In the first embodiment, the ventilation duct 9 is not configured as a separate member from the vertical beam 1a and the horizontal beam 1b of the suction grill 1, but as shown in FIG. A case where the vertical rail 1a and the horizontal rail 1b of the suction grill 1 are provided with the ventilation hole 8 facing the air filter 4 and are integrally formed in a hollow shape so as to communicate with the ventilation port 7. Will be described.

  That is, since the vertical rail 1a and the horizontal rail 1b of the suction grill 1 also serve as the ventilation duct 9, indoor air is sucked from the inlet as in the intake duct described above as the background art. The air resistance when the air is sucked is eliminated, and the suction efficiency when sucking the indoor air is not reduced. Therefore, the indoor air can be smoothly sucked from the suction hole 1c of the suction grill 1.

  The plurality of ventilation holes 8 are arranged at a predetermined interval so as to distribute the outdoor air evenly to the air filter 4, so that the outdoor air is concentrated on a specific location of the air filter 4. Therefore, the dust trapped by the air filter 4 is not blown off, and as described above, the heat exchanger 5 is supplied without any bias, so the balance of heat exchange is lost. There is no such thing.

  The vertical rail 1a and the horizontal rail 1b of the suction grill 1 are formed so as to be thicker as they are closer to the ventilation port 7 and tapered so as to be thinner as they are farther away.

  As a result, the ventilation duct 9 can be formed in a tapered shape, the outdoor air introduced from the ventilation port 7 can be effectively guided, and can be uniformly distributed over the entire area of the air filter 4. Can be distributed.

  In addition, the plurality of ventilation holes 8 uniformly distribute outdoor air introduced from the ventilation ports 7 over the entire area of the air filter 4, so that the size and position (pitch) of the plurality of ventilation holes 8 are vertical to the suction grill 1. What is necessary is just to set suitably according to the shape and dimension of the crosspiece 1a and the horizontal crosspiece 1b.

  With the above configuration, the ventilation duct 9 for introducing outdoor air to be ventilated is made hollow by using the vertical beam 1a and the horizontal beam 1b of the suction grill 1 to thereby form the vertical beam 1a and the horizontal beam. Since it is formed integrally with the crosspiece 1b, the air resistance when the room air is sucked from the suction port 2 is not increased.

  And it introduces so that outdoor air may be distributed uniformly over the whole region of the air filter 4, and it becomes an air conditioner which does not break the balance of heat exchange by supplying it to the heat exchanger 5 evenly.

It is explanatory drawing of the air conditioner by this invention, (A) is sectional drawing, (B) is principal part sectional drawing. It is explanatory drawing of the air conditioner by this invention, (A) is the top view seen from the upper part of a suction grill, (B) is the top view seen from the lower part of a suction grill. It is an enlarged view of the A section shown in FIG.
