Abstract

PURPOSE:To enable a temperature irregularity in an indoor area to be rapidly decreased by a method wherein an air guiding member moved toward an axial center of each of cross-flow fans is arranged between the crossflow fans mounted at both sides of a heat exchanger. CONSTITUTION:A mountain-shaped air guiding member 13 arranged at a central part between cross-flow fans 8 and 9 of a heat exchanging device 1 is oscillated rightwardly or leftwardly around an axis of a motor by a motor 14 buried in a casing 12 and moved toward a direction where it is crossed with an axis 15 of each of the cross-flow fans 8 and 9. As a rotating shaft of the motor 14 is rotated in a rightward direction, the air guiding member 13 is directed upward rightwardly and as the fan motor 19 is operated under this state, a suction surface area 20 at one end of the upper cross- flow fan 8 is made wide and a suction area 21 at the other end is made narrow, resulting in that an amount of air discharged from the upper blowing port is made larger than an air volume discharged from one end of the fan 8 and at the same time the amount of air discharged from the lower blowing port 4 shows a low volume at one end and higher volume at the other end. As a result, even if the heat exchanging device is installed at a corner of a room, a large amount of air is fed to a central part of the room to enable an irregular room temperature to be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an air conditioner equipped with cross-flow fans on both sides of a heat exchanger in a housing.

(b) Prior Art Conventionally, the structure of this type of air conditioner is disclosed in Japanese Patent Publication No. 58-11528.

The structure of the air conditioner shown in this publication includes cross-flow fans on both sides of a heat exchanger in the housing, and a wind guide member extending in the axial direction of the fans is provided between the fans. This member is moved so as to be substantially parallel to the axial direction of the fan. By providing such a wind guide member, for example, when this member is moved toward one cross-flow fan, the suction area of one cross-flow fan is small and the suction area of the other cross-flow fan is large. Become. As a result, the amount of air discharged from one cross-flow fan becomes smaller than the amount of air discharged from the other cross-flow fan.

(c) Problems to be Solved by the Invention By moving the wind guide member approximately parallel to the axial direction of the cross-flow fan in this way, the amount of air discharged from each cross-flow fan can be adjusted and finely tuned. Air blow control can be performed.

However, the volume of air discharged from this air conditioner is constant in each part of the outlet, so if this air conditioner is installed in a corner of the room, move the wind direction changing blade of the outlet to the center of the room. Even if they were to be directed toward the center of the room, it was difficult to blow a large amount of air toward the center of the room, and it took time to reduce the unevenness of the temperature inside the room.

The present invention enables even if the air conditioner is installed in a corner of the room,
The purpose is to quickly reduce temperature fluctuations in the room.

(d) Means for Solving the Problems In order to achieve this object, the present invention arranges cross-flow fans on both sides of a heat exchanger, and between the two cross-flow fans there is a A wind guide member that moves in intersecting directions is provided.

(*) Made by JTI If you move this member so that one end of the wind guide member approaches one end of one cross-flow fan and the other end of this member moves away from the other end of this one cross-flow fan, one cross-flow fan The amount of air discharged from one end is smaller than the amount of air that can be completely discharged from the other end.

(F) Embodiment In Figures 1 and 2, 1 is a heat exchange unit on the indoor side of a separate air conditioner, with an inlet 2 at the center of the front and outlet ports 3 and 4 above and below this inlet, respectively. It is provided. 5,6
are wind direction changing blades arranged at these air outlets 3.4. A heat exchanger 7 is housed behind the suction port 2.

Reference numerals 8 and 9 refer to cross-flow fans installed on both the upper and lower sides of this heat exchanger, 10 refers to a drain pan, 11 refers to members of the upper cross-flow fan, and 12 refers to these cross-flow fans 8.
, 9 casing. Reference numeral 13 denotes a chevron-shaped wind guide member provided in the center between both cross-flow fans, which is swung left and right around the shaft of this motor by a motor 14 embedded in the casing 12 (see solid line arrow in Figure 2). ,
That is, the wind guide member 13 moves in a direction intersecting the axis 15 of the cross flow fans 8 and 9. 16 and 17 are left and right partition plates erected inside the unit, and the bearings 18 of the cross flow fans 8 and 9 are attached to the left partition plate 16. Further, on the right side of the right partition plate 17, a fan motor 19 for moving the cross flow fans 8 and 9 is arranged.

If the rotating shaft of the motor 140 is now rotated to the right, this rotation will cause the wind guide member 13 to rise to the right as shown in FIG. In this state, when the fan motor 19 is operated, the suction area 2 at one end of the upper cross flow fan 8
0 is wide and the suction area 21 on the other end side is narrow. As a result, the amount of air discharged from the upper Suita port 3 becomes larger than the amount of air that can be completely discharged from one end of the upper cross flow fan 8.

On the other hand, due to the wind guide member 13 in the right-up position, the suction area 22 at one end of the lower cross-flow fan 9 becomes narrower, and the suction area 23 at the other end becomes wider. As a result, the amount of air discharged from the lower Suita port 4 is smaller on one end side and larger on the other end side.

Therefore, when this heat exchange unit 1 is installed in a corner of the room 24 as shown in FIG. When the cross flow fan 8.9 is operated with the wind direction changing vane 6 of the lower Suita outlet 4 directed toward the front of the heat exchange unit 1, the amount of air discharged from one end of the upper outlet 3 will change from the other end. It is larger than the amount of air being discharged, and therefore the wind speed distribution of the air completely discharged from the upper blower outlet 3 is as shown by the solid line A, and the wind reaches the center of the room.

In addition, in the lower Suita outlet 4, the amount of air discharged from one end is smaller than the amount of air discharged from the other end, so the wind speed distribution of the air discharged from the lower Suita outlet 4 is as shown by the solid line B, and the lower side A large amount of air discharged from the other end of the Suita mouth 4 flows along the wall surface 25 of the room 24, thus suppressing the occurrence of temperature unevenness in the room. Further, the wind guide member 13 can also be brought into an upward leftward position as shown in FIG. 5 by operating the motor 14, and the flow of the wind at this time becomes a solid line state. The wind speed distribution at this time is shown by solid lines A and B in Figure 4.
The area surrounded by moves in the direction of the solid line arrow.If the wind guide member 13 is oscillated periodically, the non-uniformity of the temperature inside the room will be reduced.

(g) Effects of the invention As described above, the present invention provides cross-flow fans arranged on both sides of a heat exchanger, and a wind guide that moves in a direction intersecting the axes of these fans between the two cross-flow fans. Since the plate is installed, by moving the air guide plate, the amount of air that can be discharged from one end of the outlet can be larger than the amount of air that can be discharged from the other end. Even if the heat exchange unit is installed in the corner of the room, A large amount of air can be sent to the center of the room to reduce unevenness in room temperature.
