Problems solved by technology

Therefore, there is a problem that a short circuit (short circuit) is likely to occur between the blown airflow blown from the indoor side outlet to the room and the suction airflow sucked into the indoor side suction port from the room, and the cycle of indoor ventilation is deteriorated. Reduced gas efficiency
Therefore, there is a problem that the noise from the air supply blower and the exhaust blower directly reaches the person directly below the product from the indoor air outlet and the indoor air inlet.
[0011] In addition, according to the techniques of Patent Documents 1 and 2, since the indoor air outlet is provided on the lower surface panel, the blown airflow directly touches the person directly below the product, and there is a problem of feeling a cold wind especially in winter.
[0012] On the other hand, if a louver is installed at the air outlet on the indoor side to adjust the direction of the blown airflow in order to reduce such a feeling of cold wind, there is a problem that the area of ​​the air supply port is reduced, the pressure loss of the air passage occurs, and the ventilation air volume is reduced.
[0013] In addition, according to the technology of Patent Document 3, when the simultaneous supply and exhaust type ventilating fan is installed on the ceiling surface, the main body of the product protrudes greatly from the ceiling surface.
Therefore, there is a problem that the aesthetics of the ceiling surface deteriorates, and noise directly reaches people directly below the product from the air outlet or the air inlet.

Embodiment approach 1

[0072] figure 1 It is a perspective view showing the appearance structure of Embodiment 1 of the simultaneous supply and discharge type ventilating fan of the present invention, figure 2 yes means figure 1 A perspective view of the usage state of the exhaust fan at the same time. exist figure 1 Among them, in the simultaneous supply and discharge type ventilating fan, a casing 1 is provided, and a lower surface panel 3 is installed below the casing 1 via a panel exterior frame 2 . In addition, the panel exterior frame 2 can be configured in a rectangular tube shape. In addition, as the lower surface panel 3, for example, a decorative panel can be used.

[0073] Here, the side surface of the housing 1 is provided with an exhaust port SO that discharges the exhaust airflow A2 to the outside of the housing 1 and an air supply port SI that supplies the supply airflow B1 into the housing 1 . Further, below the housing 1 , the lower panel 3 is formed with a panel suction port ...

Embodiment approach 2

[0100] Figure 6 It is an exploded perspective view showing the schematic structure of the mounting part of the decorative panel of Embodiment 2 of the simultaneous supply and discharge type ventilating fan of the present invention, Figure 7 is indicative of Figure 6 A cross-sectional view of an example of the arrangement state of the chamber 11 and the separator 12 of the simultaneous supply and exhaust type ventilating fan. exist Figure 6 and Figure 7 Among them, a panel mounting fitting 21 is provided on the lower surface of the housing 1 and fixed to the housing 1 .

[0101] Here, the outer frame of the panel mounting bracket 21 can be configured to correspond to the outer periphery of the main body opening 4 provided on the lower surface of the housing 1, and can have a rectangular cylindrical shape. In addition, on the surface of the panel mounting fitting 21 facing the housing 1, a suction side opening 21a for introducing the suction airflow A1 sucked in from th...

Embodiment approach 3

[0112] Figure 8 It is a cross-sectional view showing Embodiment 3 of the simultaneous supply and discharge type ventilation fan of the present invention cut along the flow direction of the intake airflow A1 and the outlet airflow B2. exist Figure 8 In this simultaneous supply and exhaust ventilation fan, instead of Figure 4 The lower surface panel 3 is provided with the lower surface panel 113 . Here, the lower panel 113 is configured to extend horizontally outside the panel exterior frame 2 on the suction side of the suction airflow A1 and the blowout side of the blown airflow B2 .

[0113] Furthermore, the lower panel 113 is arranged to face the ceiling surface T on the suction side of the suction airflow A1 and the blowout side of the outlet airflow B2, whereby the panel suction inlet UI' and the panel outlet UO' are formed between the lower panel 113 and the ceiling. Between faces T.

[0114] Then, the suction airflow A1 drawn horizontally from the panel suction por...

Abstract

A panel suction port (UI) and a panel discharge port (UO) are so formed by a lower surface panel (3) as to face each other, and are so disposed that the direction of the suction air flow (A1) sucked into the panel suction port (UI) is same as the direction of the discharge air flow (B2) discharged from the panel discharge port (UO), whereby the suction air flow (A1) and the discharge air flow (B2) can flow along a ceiling surface.

Description

technical field [0001] The present invention relates to a simultaneous supply and discharge type ventilation fan and an air conditioner, in particular to a simultaneous supply and discharge type ventilation fan which sucks indoor air from a panel suction port and simultaneously blows air into the room from a panel outlet. Decorative panels fixed to the ceiling. Background technique [0002] In order to realize ventilation with less variation in the state quantity in the room, there is a method of installing a simultaneous supply and exhaust type ventilation fan on the ceiling to perform simultaneous supply and exhaust while performing heat exchange. [0003] As such a simultaneous supply and exhaust type ventilating fan, Patent Document 1 discloses a simultaneous supply and exhaust type ventilating fan in which a prismatic heat exchanger is accommodated in an outer case and the heat exchanger is covered with a ceiling panel. , the external air supplied from the outside pass...
