Abstract

PURPOSE:To prevent substantially the dewing of a fitting piece and a support piece of an air-direction shifting member by providing an opening for airing in the fitting piece which bestrides a blowoff port and fixes the support piece of the air-direction shifting member. CONSTITUTION:The dimension of the width of a vertical shaft of a support piece 32 of an air-direction shifting member 9 is set to be smaller than the dimension of the width of an opening 31 of a fitting piece 26. Therefore a gap is formed when the two pieces 26 and 32 are combined. An air-conditiner being operated, indoor air is sucked into the conditioner from a suction panel, colled down in a heat exchanger and then discharged from a blowoff port 8. On the occasion, part of the air discharged from the blowoff port 8 is dis charged forward from the gap formed of the fitting piece 26 and the support piece 32. Therefore, there is no possibility of warm air passing around the support piece 32 and the air-direction shifting member 9 near to this piece, and these components and the vicinity thereof are always cooled down by cool air. Accordingly, dewing on the fitting piece 26 and the support piece 32 of the air-direction shifting member 9 can be prevented substantially.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a wind direction changing device such as an air conditioner.

(b) Conventional technology In the past, when the outlet of an air conditioner was long and narrow,
As shown in Japanese Patent No. 125150, a mounting piece that spans the air outlet is provided, and a grill having a wind direction changing blade is attached to this mounting piece.

(8) Problems to be Solved by the Invention In such an air conditioner, when cold air is discharged from the outlet, the mounting piece acts as a baffle, and the cold air discharged from around the mounting piece causes the mounting piece to Warm air sometimes circulated in front of the vehicle. If warm air circulates in front of the mounting piece in this way, dew may form on the mounting piece or the grill.

An object of the present invention is to make it difficult for dew to form on a mounting piece fixed across an air outlet and a support piece of a wind direction changing member.

(d) Means for Solving the Problems In order to achieve this object, the present invention provides a mounting piece that straddles the air outlet and to which the support piece of the wind direction changing member is fixed. It is designed to have an opening.

(*) A portion of the cold air discharged from the working outlet is applied to the support piece through the opening of the attachment piece, thereby making it difficult for warm air to flow around the support piece.

Example) In Fig. 2, 1 is a ceiling-mounted air conditioner;
It is suspended in the. 3 is a partition plate that divides the interior of the air conditioner 1 into front and rear parts; 4 is a centrifugal blower placed in the rear chamber; 5 is a suction panel placed at the bottom of the rear chamber; 6
1 is a heat exchanger disposed in the front chamber, 7 is a drain pan provided below the heat exchanger 6, 8 is a horizontally elongated outlet, and a wind direction changing member 9 is provided.

In FIGS. 1, 3 to 6, 10 is an upper member;
Reference numeral 11 denotes a lower member, and the exterior body of the air conditioner 1 is constructed by fitting the side flanges 12 of both members together and fixing them with screws. Reference numerals 13 and 14 denote left and right fixing plates that are attached across the front parts of both sides 15 of the upper member 10 and lower member 11, and the protruding pieces 17 of the lower member 11 are inserted into the lower positioning holes 16.
and insert the screw hole 19 of the upper member 10 into the upper mounting hole 18.
(see Figure 3), and tighten both members 10.1 with screws 20.
1 (see Figure 4). 21 is a motor fixed to the left side surface of the left fixed plate 13, 22 is a bearing hole into which the rotating shaft 23 of the wind direction changing member 9 is inserted, and the tip 24 protruding from this bearing hole 22 is a connecting member (not shown). ) to the shaft 25 of the motor 21. And motor 2 with
The wind direction changing member 9 swings up and down by the rotation of the shaft 25 of 1. Reference numeral 26 denotes a mounting piece that is fixed across the air outlet 8, and its upper end 27 is screwed into the back surface of the upper member 10.
8, and the lower end 29 is locked to the protruding piece 30 of the lower member 11. 31 is an opening provided in this mounting piece 26. Reference numeral 32 denotes a support piece fixed to this attachment piece 26, and a support shaft 34 of the wind direction changing member 9 is inserted into a hole 33 at the tip. This wind direction changing member 9 includes an upper plate 35 extending horizontally, three lower plates 36 formed downward from the upper plate 35 in a substantially U-shape, vertical blades 37 supported by the drawing plates, and a left and right rain cover. Board 35
．． It is composed of the above-mentioned rotating shaft 23 that protrudes from the side surface of 36, and the above-mentioned support shaft 34 that connects the lower plates.

7 and 8 show the relationship between the mounting piece 26 and the support piece 32, and the upper end 38 of the support piece 32 is connected to the opening 31 of the mounting piece 26.
is inserted at the top of the The lower end 3 of this support piece 32
9 is applied to the lower part of the opening 31 and fixed with a screw 40. By this fixation, the lower end 29 of the support piece 32, the lower end 29 of the attachment piece 26, and the protruding piece 30 of the lower member 11 are integrated. Here, since the width dimension of the vertical shaft 41 of the support piece 32 is set smaller than the width dimension of the opening 310 of the support piece 32, when the two are combined, a gap 42 is formed as shown in FIG. Ru.

Therefore, when the air conditioner 1 is operated for cooling, indoor air is sucked into the machine from the suction panel 5, cooled by the heat exchanger 6, and then discharged from the Suita outlet 8. Here, a part of the air discharged from the Suita mouth 8 is connected to the mounting piece 26 and the support piece 3.
2 (see the solid line arrow in FIG. 8), the support piece 32
There is no risk of warm air circulating around the support piece 32 or the wind direction changing member 9 near this support piece 32, and this area is always cooled by cold air. Therefore, the support piece and the wind direction changing member 9
dew will be less likely to adhere to the surface.

(G) Effects of the Invention As described above, the present invention provides an opening through which air passes through the mounting piece that straddles the air outlet and to which the support piece of the wind direction changing member is attached, so that air is discharged from the air outlet. A portion of the cold air is directed to the support piece through this opening. This makes it difficult for warm air to circulate around this support piece, making it difficult for dew to adhere to this support piece.
