Abstract

PURPOSE:To make it possible that the front area of an air blower device pro vided with a cross flow fan is suppressed small by providing space that contains an electrical equipment at the end part of the motor side of a casing that contains a fan and a motor. CONSTITUTION:A cover 49 is fitted from the upper of a mounting piece 43 and an electrical part 48 is sheathed with a cover 49, and the front part 54 and the rear 56 of a vertical piece 52 shorter than the other is fitted to the outer wall of a mounting member 42 and fixed with tape 58. And, a center part 55 is inserted into an opening 59 between the inner wall of the mounting member 43 and a limit switch 57 forming the mounting member 42 in a box shape. And, the height dimension of the mounting member 42 coincides with the height dimension of an opening 66 between the top plate 38 and the lower plate 60 of a storage part 34. Therefore, while placing the mounting member 42 lower plate 60 of the storage part 34, the mounting member 42 can be inserted from the front. Like this, the front area of an air blower device can be suppressed small eliminating the necessity of separately providing the storage space of the electrical equipment in the outside of a casing.

(c) Problems to be Solved by the Invention When the motor and electrical components are arranged outside the fan casing in this way, the area when the blower device is viewed from the front (
Hereinafter referred to as "front area". ) could become wider. Even if this front area becomes a little larger, there is relatively no problem if this device is installed on a wall, but if this device is embedded in a recess in the wall, the recess should be enlarged according to the front area of this device. This may cause problems with the installation of the equipment.

The present invention aims to reduce the front surface area of a blower equipped with a crossflow fan.

(d) Means for Solving the Problems In order to achieve this object, the present invention provides a cross-flow fan, a motor for driving this fan, and a casing in which these fans and motors are housed. The casing is provided with a space for storing the electrical components at the end on the motor side.

(e) Electrical components are arranged at the end of the functional casing on the motor side, so that the electrical components do not protrude outside the casing, and the front surface area of the blower can be kept small accordingly.

(F) Embodiment In FIG. 1, 1 is an outdoor open hallway of a housing complex (apartment), etc., and 2 is a room facing this hallway (outside), which is called a pipe shaft. This pipe shaft 2 houses an electric meter, a gas meter, a gas pipe, a water pipe, etc. (not shown). 3 is this pipe shaft 2
A service door covering the lower opening 4 of the electric meter has a meter reading window 5 for an electric meter, a meter reading window 6 for a gas meter, and a ventilation lower. In this way, the vibe shaft 2 and the open hallway (
Outdoor) 1 is not completely partitioned, but is partitioned open to the extent that children cannot enter. 8 is an outdoor heat exchange unit (hereinafter referred to as 1 blower) of a separate air conditioner, and 9 is a boiler, both of which have a rectangular parallelepiped shape, the front of which is the wall 1o of the open corridor 1. It is incorporated into the pipe shaft 2. In this way, the front surface 11 of the blower 8 and the boiler 9 is connected to the wall surface 10 of the open hallway 1.
By making the open hallway 1 flush, there are no protruding objects in the open hallway 1, making it easier to walk through the hallway. 12 is a frame installed around the opening of this vibe shaft.

The air inside the pipe shaft 2 is then transferred to the suction port 1 of the side panel 25.
8, the air outside the pipe shaft 2 is sucked into the device through the ventilation grilles 15 of the suction panel 13, respectively. After exchanging heat with the refrigerant flowing in the heat exchanger 19, it is discharged from the ventilation grille 16 of the discharge panel 14. In addition, here, the side panel 25 and one side 2 of the plate fin type heat exchanger 19
6, a gap 27 is provided between the two.

The reason why the gap 27 is provided in this way is as follows. That is, when the device 8 is housed in the pipe shaft 2 so that the side panel 25 of the blower device 8 is very close to the inner wall 28 of the pipe shaft 2, a part of the air sucked in from the ventilation grille 15 of the suction panel 13 is removed. This is to allow the portion to pass around to one side 26 of the plate-fin type heat exchanger 19 via the gap 27. 29 is a compressor, and 30 is an accumulator.

FIG. 4 is a perspective view showing the side panel 25, suction panel 13, discharge panel 14, service panel 17, etc. of this blower device 8 with the exterior body removed, and numeral 31 is the bottom plate of the blower device; An exchanger 19, a casing 21, a compressor 29, etc. are mounted.

Reference numeral 34 denotes a storage section formed in the lower part of the casing 21, and a space inside the storage section 34 (described later) stores electrical components, which will be described later. Although the front part 36 of the side plate 35 of this storage part extends directly below from the scroll part 23 of the casing 21, the rear part 37 of the side plate 35 of this storage part 34 projects outward from the scroll part 23 of the casing 21. In other words, storage section 3
The side plate 35 of No. 4 extends straight rearward from the front portion 36, whereas the scroll portion 23 of the casing 21 curves inward from the front to the rear. 38 is this storage part 3

The height of the mounting member 42 matches the height of the space 66 between the top plate 38 and the bottom plate 60 of the storage section 34. Therefore, the mounting member 42 can be inserted from the front while being placed on the lower plate 60 of the storage portion 34. 61
is a hole provided in the scroll portion 23 through which a lead wire (not shown) is inserted and connected to the electrical component 48.

When the mounting member 42 is fixed inside the end portion of the casing 21 in this manner, the terminal board 44 fixed to the front surface of the mounting member 42 is positioned in front, as shown in FIG. Note that this terminal board 44 is covered with a service panel 17 (see FIG. 2).

Furthermore, when removing the cross-flow fan 20 during service inspection, pull the mounting member 42 forward a little as shown in FIG. When the screw of the boss 63 of the cross flow fan 20 is turned, the boss 63 of the cross flow fan 20 is removed from the shaft 65 of the motor 64.

(G) Effects of the Invention As described above, the present invention has electrical equipment stored at the end of the motor side of the casing housing the cross flow fan and the motor that drives this fan. There is no need to provide a separate space outside the casing, and the front area of the blower can be kept small. Furthermore, when the blower device is embedded in the wall of a house, the recess in the wall for embedding can be made smaller. Furthermore, since the space in the casing in which the electrical components are housed does not function as a ventilation path, the inside of the casing can be used effectively.
