Embodiment approach 1

[0049] Embodiment 1 of the present invention will be described based on FIGS. 1 to 4 .

[0050] As shown in Figures 1 and 2, on the box-shaped body 1, a louver 5 having an indoor suction port 3 for sucking in indoor air 2, an indoor air outlet 4 for blowing air into the room, and an outdoor window for sucking in outdoor air 6 are provided on the side of the box-shaped body 1. Suction port 7, the outdoor air outlet 8 that blows out air to the outside. In the central part of the body 1, a motor 11 is provided with an exhaust blade 9 and an air supply blade 10 that blow air as it rotates.

[0051] Furthermore, the motor 11 is disposed on a motor fixing plate 14 provided between the exhaust fan case 12 and the air supply fan case 13 . The distance from the suction surface 15 of the exhaust fan case 12 to the motor fixing plate 14 is equal to the distance from the suction surface 15 of the air supply fan case 13 to the motor fixing plate 14 . In addition, an exhaust fan case 12 i...

Embodiment approach 2

[0071] Fig. 5 is a side sectional view showing a supporting structure of the motor, and Fig. 6 is a state in which the motor is mounted on the ceiling. In FIGS. 5 and 6 , the same reference numerals are used for the same parts as those in FIGS. 1 to 4 . As shown in Fig. 5 and Fig. 6, two supporting members 38 are fixed on two opposite sides 37 of the body 1, the motor fixing plate 14 is fixed on the two supporting members 38, and the motor 11 is fixed on the motor fixing plate 14. . In addition, two hangers 39 are respectively fixed to the two support members 38 .

[0072] Based on the above configuration, the weight of the motor 11 is held by the four hangers 39 via the motor fixing plate 14 and the two support members 38 .

[0073] Therefore, when the machine body 1 is suspended, the weight of the electric motor 11 as a heavy object can be sufficiently supported by the supporting member 38 . Therefore, since the body 1 having a large surface area does not require much str...

Embodiment approach 3

[0075] Embodiment 3 will be described based on FIG. 7 and FIG. 8 . Fig. 7 is a front sectional view of the heat exchange device, and Fig. 8 is a bottom sectional view. In FIGS. 7 and 8 , the same reference numerals are used for the same parts as those in FIGS. 1 to 6 .

[0076] Compared with Embodiment 1, which directly performs indoor air supply and exhaust, Embodiment 3 differs from it in that the indoor air supply and exhaust are carried out from the main body through pipes.

[0077] As shown in Fig. 7 and Fig. 8, the indoor suction port 3 for sucking in indoor air 2 and the indoor blowing port 4 for blowing air indoors and the outdoor suction port 7 for sucking in outdoor air 6 and blowing out air to the outside are set on the side of the box-shaped body 1. The outdoor blowing outlet 8 of air. In the central part of the body 1, a motor 11 is provided with an exhaust blade 9 and an air supply blade 10 that blow air as it rotates. The motor 11 is arranged on the motor fix...

Abstract

A heat exchanger of small size and thin type is provided. It includes a machine body (1), an indoor suction port (3) for sucking indoor air (2), an indoor diffuser (4), an outdoor suction port (7) for sucking in outdoor air (6), an outdoor diffuser (8), a motor (11) provided inside the machine body (1), an exhaust blade (9) and an intake blade (10) disposed at the motor (11), an exhaust fan casing (12) provided around the exhaust blade (9), an intake fan casing (13) provided around the intake blade (10), and a plurality of heat exchange elements (16) disposed around the exhaust fan casing (12) and intake fan casing (13).

Description

technical field [0001] The present invention relates to heat exchange equipment for indoor air exchange through the air supply by fan motor and heat exchange by heat exchange elements for indoor air and outdoor air, especially relates to the realization of compact heat exchange equipment and reduction of ventilation path resistance Technology. Background technique [0002] 12 to 14 show a first conventional example of a heat exchange device. Fig. 12 is a front sectional view, Fig. 13 is a construction drawing when installing to a wall surface, and Fig. 14 is a construction drawing when installing to a ceiling surface. [0003] The main body 101 roughly consists of exhaust blades 102 , air supply blades 103 , a motor 104 for rotating them, and a plurality of heat exchange elements 105 . On the indoor surface side of the main body 101, a louver 108 having an indoor side suction port 106 for sucking in indoor air and an indoor side discharge port 107 for blowing air into the ...
