Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a size-up frame for a ceiling-mounted device including a rectangular ceiling-mounted device housed in a ceiling such as a ceiling-embedded air conditioner.
[0002]
[Prior art]
In general, a ceiling opening device such as a ceiling-embedded air conditioner in which a rectangular opening is provided in a ceiling plate of a house and a rectangular ceiling mounting device is accommodated in the opening without any gap is known. . With this type of equipment, when replacing old ceiling-mounted equipment with new ones, the size is usually more compact than the previous model. In the case of housing, a size-up frame is generally used to close the gap between the ceiling-mounted device and the opening.
[0003]
[Problems to be solved by the invention]
The conventional sizing frame is composed of corner parts and straight parts, each corner part is provided with a corner part, and each corner part is connected by a straight part. However, according to the conventional configuration, there is a problem that the number of parts increases and it is difficult to close the gaps between the connecting portions.
[0004]
Accordingly, an object of the present invention is to provide a size-up frame for a ceiling-mounted device that eliminates the problems of the conventional techniques described above, reduces the number of parts, and can easily close gaps of various sizes. There is to do.
[0005]
According to a first aspect of the present invention, in the size-up frame for a ceiling-mounted device in which a rectangular opening is provided in the ceiling plate and the rectangular ceiling-mounted device is accommodated in the opening without any gap, the outer shape is larger than the opening of the ceiling plate. Upon accommodating the small ceiling mount device of the opening has a size up frame for closing the gap between the ceiling mount devices and the opening, the size-up frame, stepped to the edge of the ceiling mounting apparatus side It has a recess, and the step recess is fixed to the decorative panel from the back of the decorative panel edge of the ceiling mounting device, and the surface of the upsized frame and the surface of the ceiling mounting device are formed so as to be smoothly connected. It is characterized by that.
[0006]
According to the present invention, for example, after the size-up frame is attached to the ceiling-mounted device, the ceiling-mounted device can be closed without any gap by storing the ceiling-mounted device in the ceiling opening.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a size-up frame for a ceiling-mounted device according to the present invention will be described with reference to the accompanying drawings.
[0008]
FIG. 1 shows a ceiling-embedded air conditioner. The air conditioner 1 is an air conditioner (ceiling mounting device) called a four-way ceiling cassette type air conditioner, and includes a main body 2 and a decorative panel 3. The main body 2 is accommodated in the ceiling back 4, and a heat exchanger, a blower and the like (none of them are shown) are accommodated therein.
[0009]
The decorative panel 3 is disposed below the main body 2 so as to be substantially flush with the surface of the ceiling board 5. Reference numeral 6 denotes a suction grille, which is attached to the approximate center of the decorative panel 3. Reference numerals 7 a, 7 b, 7 c, and 7 d are air outlets and are provided around the suction grill 6. When the operation of the blower (not shown) is started, the indoor air is sucked into the suction grill 6 and then cooled, for example, in a heat exchanger (not shown), and then the four-way outlets 7a, 7b, 7c. , 7d. At this time, the wind blown out from each of the air outlets 7a, 7b, 7c, 7d is framed from the outer surface of each of the air outlets 7a, 7b, 7c, 7d of the decorative panel 3 as shown by solid arrows. It flows smoothly along the surface of 104.
[0010]
According to this embodiment, a rectangular opening 200 is formed in the ceiling plate 5, and a gap 210 is formed between the opening 200 and the outer periphery of the main body 2. The gap 210 is formed in this way for the following reason.
[0011]
That is, when this type of air conditioner 1 is replaced with a new type of air conditioner 1 in order to increase horsepower or the like, since the size is improved, the size is made more compact than the conventional model. It is normal.
[0012]
When the new air conditioner 1 having a reduced size is accommodated in the opening 200 in which the conventional model is accommodated, the air conditioner 1 inevitably has a gap between the decorative panel 3 and the opening 200. A gap 210 is formed.
[0013]
According to this embodiment, in order to close this gap 210, a resin-made size-up frame 100 configured as follows is used.
[0014]
As shown in FIGS. 2 and 3, the size-up frame 100 is configured by a combination of four frame parts 101 to 104 each formed in a substantially L shape. FIG. 2 shows a size up frame 100 for a 3-horsepower air conditioner, and FIG. 3 shows a size-up frame 100 for a 5-horsepower air conditioner. Including three horsepower and five horsepower air conditioners, the four frame parts 101 to 104 are formed to have the same length of the bent portions 101a to 104a. On the other hand, the length of the long bent portions 101b to 104b can be appropriately changed according to the size, shape, etc. of the size-up frame 100.
[0015]
Since the four frame parts 101 to 104 can be manufactured using a single mold (not shown), the manufacturing is easy. Specifically, the length of the long bent portions 101b to 104b can be changed by inserting a nest (not shown) into a mold (not shown).
[0016]
Next, a procedure for attaching the size-up frame 100 will be described.
[0017]
As shown in FIG. 4, stepped recesses 110 are formed in each of the frame parts 101 (˜104). A side edge 7 a of the decorative panel 7 is fitted into the stepped recess 110, and the decorative panel 7 and the frame component 101 (˜104) are coupled by a plurality of screws 113. According to this, the upsized frame 100 is screwed to the decorative panel 7, and the decorative panel 7 integrated with the upsized frame 100 is coupled to the main body 2. At this time, as shown in FIG. 1, the surface of the decorative panel 7 of the air conditioner 1 and the surface of the upsized frame 100 are formed so as to be smoothly connected.
[0018]
In short, according to this embodiment, the size-up frame 100 is composed of a combination of four frame parts 101 to 104 formed in a substantially L shape, and each frame part 101 to 104 is a corner part integrated type. Assembling work becomes easy, and the number of parts can be reduced as compared with the conventional one. Moreover, since each frame component 101-104 can be manufactured with a single metal mold | die, while being able to reduce the cost of a metal mold | die, the manufacturing cost of the frame components 101-104 can also be reduced.
[0019]
Further, since the surface of the decorative panel 7 and the surface of the size-up frame 100 are formed so as to be smoothly connected, the wind blown from each of the air outlets 7a, 7b, 7c, 7d 7a, 7b, 7c, 7d smoothly flows along the surface of the frame parts 101-104 from the outer surface of the frame part. Further, by attaching the upsized frame 100, the outer sides of the outlets 7a, 7b, 7c, 7d Therefore, the blowing air flows downward from the position of the size-up frame 100. As a result, the blown-out air is less likely to hit the ceiling surface, so that smudging on the ceiling plate 5 can be suppressed and dirt on the ceiling surface can be reduced.
[0020]
While the present invention has been described based on one embodiment, the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the method for attaching the size-up frame 100 has been described. However, the method is not limited to this method, and for example, the size-up frame 100 can be attached to the main body 2.
[0021]
【The invention's effect】
As described above, according to the present invention, the size-up frame is formed so as to smoothly connect the surface of the size-up frame and the surface of the ceiling-mounted device, so the wind blown from each outlet is It smoothly flows from the outer surface of each outlet of the decorative panel to the surface of the frame component, so that smudging to the ceiling surface is suppressed to a low level, and the work for attaching the upsized frame can be performed safely and easily .
