However, according to the techniques of Patent Documents 1 and 2, the indoor side air outlet and the indoor side air inlet are provided on the same surface or adjacent positions on the lower panel of the room. Therefore, a short circuit is likely to occur between the blown airflow blown from the indoor side air outlet to the indoor air and the air intake air sucked from the indoor air to the indoor side suction port, resulting in deterioration of the cycle due to indoor air exchange, and thus the ventilation efficiency is lowered. The problem.

Further, according to the techniques of Patent Documents 1 and 2, the lower side panel of the product main body is provided with an indoor side air outlet and an indoor side air inlet. Therefore, the noise from the air supply blower and the exhaust fan is directly from the indoor side air outlet and the indoor side air inlet to the person directly below the product, which is a problem.

Further, according to the techniques of Patent Documents 1 and 2, since the indoor side air outlet is provided on the lower panel, the blown airflow directly faces the person directly below the product, particularly in winter, and there is a problem of a sense of wind sensation.

On the other hand, if the louver for adjusting the wind direction of the blown airflow is provided in the indoor side air outlet to reduce such a feeling of exhaustion, the area of the air supply port becomes small, and the air passage pressure is lowered, so that the ventilation air volume is lowered. problem.

Moreover, according to the technique of Patent Document 3, if the ventilating fan is simultaneously provided on the ceiling, the product body easily protrudes from the ceiling. Therefore, there is a problem that the design of the ceiling is poor, and the noise directly reaches the person directly below the product from the air outlet or the suction port.

The present invention has been made in view of the above circumstances, and an object of the invention is to provide a simultaneous discharge type ventilating fan and an air conditioner which can suppress occurrence of a short circuit between a blown air stream blown out into a room and a suction air stream sucked from a room.

In order to solve the above problems and achieve the object, the simultaneous ventilating fan of the present invention is characterized in that it comprises an outer casing which forms mutually independent exhaust ventilation ducts and air supply ducts, and is disposed under the outer casing and with the panel. a lower surface of the suction port and the panel outlet which are formed to face each other, and an exhaust gas that is accommodated in the outer casing and that transports the suction airflow that is sucked into the panel suction port to the exhaust air passage and is discharged as an exhaust gas flow The blower and the air supply blower that are accommodated in the outer casing and that feed the airflow to the air supply duct to the panel air outlet and are blown out as a blow-out flow.

According to the present invention, it is possible to suppress the occurrence of a short circuit between the blown airflow blown out into the room and the intake airflow sucked from the room.

The embodiment of the present invention for the simultaneous arrangement of the ventilating fan will be described in detail below based on the drawings. Further, the present embodiment does not limit the present invention.

The first embodiment type.

Fig. 1 is a perspective view showing an appearance configuration of a first embodiment of a ventilating fan of the present invention, and Fig. 2 is a perspective view showing a state in which a ventilating fan is supplied while the first drawing is being used. In Fig. 1, the outer casing 1 is provided on the ventilating fan at the same time, and the lower panel 3 is attached to the lower casing 1 through the panel outer frame 2. Further, the panel exterior frame 2 may be formed in a rectangular tube shape. Also, the lower panel 3 may be a decorative panel.

Further, under the outer casing 1, a panel suction port UI for sucking the suction airflow A1 and a panel air outlet U0 for blowing the blown airflow B2 are formed through the lower panel 3.

Here, the panel suction port UI and the panel air outlet U0 may be formed through the lower panel 3 in a facing manner. In this case, it is preferable that the panel suction port UI and the panel air outlet U0 are formed along the lower panel 3 in such a manner that the direction of the suction airflow A1 sucked into the panel suction port UI and the blown airflow B2 blown from the panel air outlet U0. The direction is the same direction.

The sixth embodiment.

Figure 11 is a cross-sectional view showing a sixth embodiment of the air conditioner of the present invention in a mode. In Fig. 11, an air-conditioning device is provided with an outer casing 201, and below the outer casing 201, a lower panel 203 is attached through the panel outer frame 202. In addition, the panel outer frame 202 may be in the shape of a square cylinder. Also, the lower panel 203 may employ a decorative panel.

Further, below the outer casing 201, a panel suction port UI for sucking the suction airflow A1 and a panel air outlet U0 for blowing the blown airflow B2 are formed on the lower panel 203.

Here, the panel suction port UI and the panel air outlet U0 may be formed on the lower panel 203 so as to face each other. In this case, the panel suction port UI and the panel air outlet U0 are formed along the lower panel 203, and the direction of the suction airflow A1 sucked into the panel suction port UI and the direction of the blown airflow B2 blown from the panel air outlet U0 should be configured to be the same. direction.

Further, in the outer casing 201, an air supply and exhaust duct 206 for ensuring an air passage between the panel suction port UI and the panel air outlet UO is provided. Further, a fan 204 and a heat exchanger 205 are provided on the exhaust air passage 206. Here, the heat exchanger 205 can adjust the temperature of the suction airflow A1 sucked from the panel suction port UI. On this heat exchanger 205, a compressor, a condensing gas, and an evaporator can be disposed. The fan 204 allows the intake airflow A1 to be sucked into the suction port UI, and is blown out from the panel air outlet U0 as the blown airflow B2.

Further, when the indoor suction airflow A1 is sucked from the panel suction port UI, the suction airflow A1 is guided into the outer casing 201. Then, the suction airflow A1 guided into the outer casing 201 is heat-exchanged by the heat exchanger 205, and then blown out into the room from the panel air outlet U0 as the blowing airflow B2.

Here, the panel suction port UI and the panel air outlet U0 are formed on the lower panel 203 so as to face each other, whereby the direction of the suction airflow A1 sucked into the panel suction port UI and the blown airflow blown from the panel air outlet U0 can be made. The direction of B2 is the same direction. Therefore, the intake airflow A1 and the blown airflow B2 can be circulated along the ceiling, and the occurrence of a short circuit can be suppressed between the blown airflow B2 and the intake airflow A1, so that the air-conditioning efficiency can be further improved.

Further, in the sixth embodiment of the eleventh embodiment, the air conditioner has been described by taking an air conditioner as an example. However, a filter filter may be used instead of the heat exchanger 205 to be applied to the air cleaner. Further, the filtration filter may be a dust collection filter, a deodorizing filter, a sterilization filter, or the like.

[Industry profitability]

As described above, the suction airflow and the blown airflow of the ventilating fan of the present invention can flow in the same direction along the ceiling surface, and are suitable for suppressing a short circuit between the blown airflow blown out into the room and the suction airflow sucked from the room.
