Embodiment approach 1

[0049] About Embodiment 1 of the present invention according to Figure 1 ~ Figure 4 Be explained.

[0050] Such as figure 1 and figure 2 As shown, the box-shaped body 1 is provided with an indoor suction port 3 for inhaling indoor air 2 and an indoor blowing port 4 for blowing air indoors, and an outdoor suction port 7 for sucking in outdoor air 6 is provided on its side surface. Outdoor blowing port 8 for blowing air. In the central part of the body 1, the electric motor 11 is equipped with an exhaust blade 9 and an air supply blade 10 that blow air along with the rotation.

[0051] Furthermore, the electric motor 11 is arranged on a motor fixing plate 14 provided between the exhaust fan housing 12 and the air supply fan housing 13. The arrangement is such that the distance from the suction surface 15 of the exhaust fan housing 12 to the motor fixing plate 14 is equal to the distance from the suction surface 15 of the air supply fan housing 13 to the motor fixing plate 14. In...

Embodiment approach 2

[0071] Figure 5 Is a side sectional view showing the support structure of the motor, Image 6 It is the installation state where the motor is installed on the ceiling surface. Figure 5 , Image 6 In and Figure 1 ~ Figure 4 The same symbols are used for the same parts. Such as Figure 5 and Image 6 As shown, two supporting members 38 are fixed on two opposite side surfaces 37 of the body 1, a 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 fixed to the two support members 38, respectively.

[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 body 1 is suspended, the supporting member 38 can sufficiently support the weight of the electric motor 11 as a heavy object. Therefore, the body 1 with a large surface area is not required to have mu...

Embodiment approach 3

[0075] according to Figure 7 and Picture 8 The third embodiment will be described. Figure 7 Is the front cross-sectional view of the heat exchange equipment, Picture 8 It is a bottom cross-sectional view. Figure 7 , Picture 8 In and Figure 1 ~ Figure 6 The same symbols are used for the same parts.

[0076] Compared with the method of directly performing indoor air supply and exhaust in the first embodiment, the third embodiment is different from the method in that the indoor air supply and exhaust is performed from the main body through a duct.

[0077] Such as Figure 7 and Picture 8 As shown, the side of the box-shaped body 1 is provided with an indoor suction port 3 for sucking in indoor air 2, an indoor blowing port 4 for blowing air into the room, an outdoor suction port 7 for sucking outdoor air 6 and an outdoor blowing port 8 for blowing air to the outside. . In the center of the body 1, the electric motor 11 is equipped with an exhaust blade 9 and an air supply blad...

Abstract

A small-sized and thin heat exchanger, comprising a frame (1), an indoor suction port (3) sucking an air (2) inside a room, an indoor discharge port (4), an outdoor suction port (7) sucking an air (6) outside the room, an outdoor discharge port (8), a motor (11) installed inside the frame (1), a discharge vane (9) and a supply vane (10) disposed on the motor (11), a fan casing (12) for discharge installed around the discharge vane (9), a fan casing (13) for air supply installed around the supply vane (10), and a plurality of heat exchange elements (16) disposed around the discharge fan casing(12) and the supply fan casing (13).

Description

Technical field [0001] The present invention relates to a heat exchange device that ventilates indoor air by passing indoor air and outdoor air through air supply by a fan motor and heat exchange by a heat exchange element for indoor ventilation, and in particular to the realization of compact heat exchange equipment and reduction of ventilation path resistance Technology. Background technique [0002] Figure 12 ~ Figure 14 Shows the first conventional example of heat exchange equipment. Picture 12 Is a front sectional view, Figure 13 It is the construction drawing when installing on the wall, Figure 14 It is a construction drawing when installing on the ceiling surface. [0003] The main body 101 is roughly composed of exhaust blades 102 and air supply blades 103, a motor 104 that rotates them, and a plurality of heat exchange elements 105. On the indoor surface side of the main body 101, a shutter 108 is installed, which has an indoor side suction port 106 for sucking in indo...
