Abstract

PURPOSE:To enable regulation of the direction of discharge air and to enable hot air to flow to the central part and the lower part of a room despite of a mounting position by a method wherein a flap mounted to a horizontal blade at a topmost part is slid by means of a linear rod. CONSTITUTION:Since the length of the horizontal part of a linear rod 5 secured to a flap 3 is longer than that of a horizontal blade 1a, the flap 3 can be longitudinally slid through the linear rod 5 by means of a groove serving as a guide. When discharged air does not flow to the lower part of the ventral part of a room, by pulling the flap 3 this side, this action is substantially the same as that in which the depth of the horizontal blade 1a is increased, and performance to regulate the direction of an air current is improved. Since, when the flap 3 or horizontal blades 1a, 1b, and 1c are inclined downward, the horizontal blade 1a is inclined together with the flap 3, discharged hot air being about to rise is effectively suppressed by means of the flap 3 and produces a descending air flow. The use of the flap 3 improves air flow distribution and provides comfort heating.

Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Application in Industry> The present invention relates to a wooden grill for an indoor unit of an air conditioner.

<Prior Art> As a conventional wooden blow-out grill for an indoor unit, there is one described in, for example, Japanese Utility Model Publication No. 14257/1983. This air outlet grill for indoor units has a thin profile by making the longitudinal length of the plurality of horizontal blades, that is, the depth dimension, relatively short. I try not to stick out.

<Problems to be Solved by the Invention> However, in the conventional indoor unit blowout grill described above, the length of the horizontal blade in the front-rear direction is short, so that the direction of the blowout air cannot be sufficiently adjusted. Therefore, during heating, warm air blows upwards indoors.1. If an indoor unit using this Suita grill is attached to the upper part of a wall, there is a problem in that warm air does not reach the center of the room, the L part.

Therefore, the purpose of the present invention is to adjust the direction of the blowing air as desired even when the length of the horizontal blade in the front and rear direction is too long for one person to achieve the desired airflow distribution. To provide a wooden primary outlet grill for an indoor unit, which can reach the center and lower part of the room regardless of the installation position of the indoor unit.

Means for Solving the Problems> In order to achieve the above object [1], the wooden air blower for an indoor unit of the present invention has a plurality of tiltable wooden horizontal blades. It is characterized by the fact that wooden flaps are placed on top of the bipedal horizontal blades located at the top of the grill, and that they are attached to the grill by wire rods so that they can slide back and forth.

In addition, the wooden air outlet grille for an indoor unit of the present invention has a wooden flap fixed to both ends of a wire rod in the shape of a mouth whose horizontal part is longer in the front and back direction than the water sea lion blade located at the top. The horizontal part of the mouth-shaped wire rod is positioned at the uppermost part and fits into the groove formed in the horizontal blade, and the horizontal part and the flap sandwich the horizontal blade. It is characterized in that a flap is attached to the water ski blade so as to be slidable in the front-back direction.

<Function> When the flap attached to the uppermost two horizontal blades is slid forward along the horizontal blade with a wire rod, the length and width of the uppermost horizontal blade in the front-rear direction increase. This is substantially the same as the above, and if the horizontal blade is tilted in the 1: direction, the flaps will tilt downward together with the horizontal blade. Therefore, the length of the horizontal blade at the Lmost part becomes longer, and the same ID effect as that of F) can be obtained, so even if the indoor unit is installed on the L side of the room, the warm air will flow directly into the room. It can reach the bottom center.

Further, the horizontal blades and the flaps are overlapped, and only when necessary, the flaps are slid and pulled out to protrude forward. Therefore, [)7 of the outlet grill
j The direction of the blowing air can be effectively controlled without increasing the dimension in the rear direction.

Also, since the horizontal blades are made of wood, 10 parts of water from a wire rod made of non-condensing material such as plastic or flocked hair is slid into the grooves, and the contact noise is small.
Due to the proper friction and elasticity of the book, the feeling when moving the flap is also good. Furthermore, since the horizontal portion of the wire rod fits into the groove of the horizontal blade, the flap is guided back and forth and does not shift laterally.

Furthermore, since the flap is made of wood, the wire rod in the shape of a mouth can be easily fixed by driving both ends into the flap, and can be manufactured easily and inexpensively.

<Example> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

FIG. 1 (aXb) is a sectional view of a blow-off grill for an indoor unit according to an embodiment of the present invention, and FIGS. 2 and 3 are perspective views of essential parts, respectively. In these figures, 1a.

lb and Ic are wooden horizontal blades capable of tilting FIJ, 3 are these horizontal blades 1 a, ] b, 1. The wooden flap 5 is attached to the -L side of the horizontal blade 1a located at the top of e, and the two-legged flap 3 is attached to the horizontal blade 1a above.
This is a plastic wire rod with a mouth shape used for attaching it to.

4-The front and rear ends of the horizontal blade 1a are tapered, and as shown in FIG. It is shallow and deep at the tapered front and rear ends.

FIG. 2 is a diagram showing the back surface of the flap 3, that is, the surface facing the horizontal blade 1a. As shown in this figure, the surface of the flap 3 facing the horizontal blade 1a has a horizontal blade. Two round holes 9 are provided in the front and rear directions at positions corresponding to the grooves 7 of 1a.

This round hole 9.9 is for inserting and fixing the wire rod 5 into it. Then, by inserting and fixing the tips of both vertical portions 5b, 5b into the round holes 9 of the flap 3, the flap 3 is taken up by the horizontal blade 1a, as shown in FIG. -1- As is clear from the figure, the length of the flap 3 in the front-rear direction, that is, the depth dimension, is longer than that of the horizontal blade 1a, and the flap 3 is longer than the horizontal blade 1a. The length of the wire rod 5 fixed to the shaft 3 in the front-rear direction, that is, the length of the part 5a of the water 17 is also longer than that of the horizontal blade 1a. The tube 3 can be slid forward and backward using the wire rod 5 and the rod 7 as a guide. In FIG. 1, (a) is a diagram showing a state in which the flap 3 is located one or two points farthest back, and at this time, ifj of the wire rod 5
The other vertical portion sb is provided at the end in the horizontal state m1aO and engages with the meni groove 7. Like the surface, the +i'li pant part is deep and the wire rod 5 is difficult to see from the surface, and the wire rod 5 does not deteriorate the appearance. In addition, (b) is a diagram showing a state in which the flap 3 is in the most forward position. 7 is engaged. As shown by two-dot chain lines, horizontal blades 1 a, l b,
When lc is tilted downward, the flap 3 is also tilted as the main flat wing 111a is tilted.

When the indoor unit of the air conditioner having the wooden outlet grille with the above configuration is attached to the upper part of the room and heating operation 1 is started, the warm air blown out from the outlet grille reaches the lower center of the room. If the horizontal blade 1a is pulled forward by hand, the depth dimension of the horizontal blade 1a becomes substantially the same as that of the larger horizontal blade 1a, and the ability to adjust the direction of the airflow is improved. Manoni, flap 3sj = horizontal blades 1a, lb,
When the l c is tilted downward, the horizontal blade 1a and the flap 3 are tilted together, and the warm air blown out rises by 1° and reaches 1°. 3 effectively suppresses the air, resulting in a downward airflow as shown by the white arrow.

In this way, according to this embodiment, the airflow distribution is improved by using the flap 3, so that comfortable heating can be obtained. In addition, since the horizontal blade 1a is made of wood, the contact resistance when the plastic wire rod 5 slides across the horizontal blade FA is small, so that the flap 3. T) In addition to being able to put in and take out smoothly, it is also possible to put in and take out smoothly.
Ru. The soil, riko, and wire rod 5 are heated by +3,000,'7, so there is no condensation. Also, attaching the flap 3 to the water 1 and the blade 1a: Attach the horizontal part 5a of the wire rod 5 to the water
Since it is a cylindrical structure in which the vertical part 51) is simply inserted and fixed into the groove 7 of the flap 3, the number of assembly steps is not increased, and it is inexpensive. can be done.

In the above embodiment, the wire rod 5 was made of a material that does not cause condensation, but it is preferable to use a material with flocked hair on the surface to prevent condensation. may be made of metal or the like.

Further, in the above embodiment, the flap 3 is attached above the horizontal blade 1a, but as shown in FIG. 4, it may be attached below the horizontal blade 1a. At this time, since the groove 7 of the horizontal blade 1a is formed over the entire circumference, the flap 3
If the surface having the round hole 9.9 is placed so as to face the lower surface of the blade 1a, the subsequent steps are the same as in the above embodiment.

fJO, the groove 7 is not necessarily provided around the entire circumference of the horizontal blade 1a (it is not necessary to pull it; when the flap 3 is attached to the upper side of the horizontal blade 1a, it is attached to the bottom side of the horizontal blade 1a, and the flap 3 is attached to the bottom side of the horizontal blade 1a). When attached to the lower side of the horizontal blade 1a, it may be installed on one side of the horizontal blade 1a.

As shown in FIG.
2 is fine.

Further, in the above embodiment, a groove 7 is drawn in the horizontal blade 1a, a wire rod 5 is engaged with the groove 7, and both ends of the wire rod 5 are inserted and fixed into the round hole 9.9 of the flap 3, and the wire Although the rod 5 is configured to slide into the groove 7, a notch of appropriate depth is made at the front and rear of the flap, and a wire rod is passed through both of these notches (7, so that the tip of this wire rod is fixed to the horizontal blade. In this case, since the wire rod is fixed to the horizontal blade, the wire rod itself will not move, but the flap will move 1iiii backward using the notch as a guide. Since the wire rod itself does not move even when it moves, it does not appear outside the frame of the outlet grille, resulting in an excellent design.

<Effects> As is clear from the above, according to the present invention, in the wooden outlet grill of an indoor unit having a plurality of tiltable wooden horizontal blades, a wooden flap is superimposed on the horizontal blade located at the top. Since it is attached so that it can be slid back and forth with a wire rod, even if the horizontal blade cannot be made very large in the front-back direction, by sliding the flap and pulling it forward, the i of the horizontal blade located at the top can be adjusted.
ηIt is virtually the same as the rear dimension has increased,
In addition, since the flaps are tilted together with the horizontal blades, the direction of the airflow can be easily and reliably adjusted, suppressing the rise of warm air during heating and improving airflow distribution.

In addition, the horizontal blades and flaps are overlapped, and the flap can be slid forward and protruded only when necessary, so the controllability of the blowout air can be improved without increasing the front and rear dimensions of the blowout grille. You can improve.

In addition, since the horizontal blades are made of wood, the contact resistance against wire rods such as plastic is low, and the flap can be smoothly inserted and removed, and the contact noise of the flap when sliding is not large, so it is not unpleasant to the ears.

In addition, since the wooden horizontal blades and flaps are movably connected using wire rods, they can be manufactured at low cost.

Further, according to the present invention, since the horizontal portion of the U-shaped wire rod is fitted into the groove of the horizontal blade, the flap is guided back and forth and does not shift laterally. In addition, since the flap is made of wood, the U-shaped wire rod can be easily fixed by driving both ends into the flap, and the tube can be manufactured at low cost.
