As shown in the Hespoord Heater etc. air conditioner?
2, front panel 2 and rear panel on the front and back of the bag holder!
, with side force bars 5 attached to both sides,
The roof 3, which serves as an air inlet and an air outlet, is divided into a plurality of parts and is attached so as to be slidable in the left and right directions.

This type of heating heater requires installation work on the wall, especially for commercial use, and also requires AC200Vi.
Often used in tfi. In addition, in the construction type that requires electrical wiring work to the main body, there are many cases in which several units are connected together to obtain the required heating capacity according to the size of the room. Therefore, as shown in the internal wiring diagram in Fig. 17, the construction type Heapod heater is equipped with two terminal blocks 9 so that feed wiring can be carried out between the Heapode heaters connected on both sides, and each of these The terminal blocks 9 are internally connected to each other.

That is, in FIG. 17, cable 2l is the power line to the first pacepod heater, and cable 2l is the power line to the first pacepod heater.
2 is a feed line for connecting and wiring from the first unit to the second unit. As described above, in the construction type headboard heater, since the electrical wiring work is performed with the main body attached to the wall surface, it is a necessary condition that all electrical wiring work can be done from the front of the main body. Therefore, in the conventional example,
For example, when the front panel 2 is removed, the terminal blocks 9 at both ends are exposed.

(Problem to be Solved by the Invention) By the way, in order to carry out electrical wiring work from the front of the device, the minimum space required is only to expose the terminal block, but in the conventional example mentioned above, the entire front panel must be removed. The problem was that it was heavy and long, making it difficult for one person to work on it, and that the removed front panel got in the way during wiring work, impairing workability during construction. Furthermore, if a portion of the front panel is deformed due to impact or the like, there is a problem in that the entire front panel must be repaired or replaced.

In particular, in the case of school air conditioners, deformation often occurs due to rough handling such as students hitting the poles or kicking them, resulting in large costs for repair or replacement, or they are left unattended until the deformation becomes large enough to make the equipment look unsightly. There was also the issue that it was causing a loss.

This invention was made to solve this problem, and its purpose is to improve workability during electrical wiring work, etc., and to repair parts that are accidentally deformed. ．． An object of the present invention is to provide a construction type air conditioner that is easy to replace.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides that a mesh-like louver forming an air inlet and an air outlet is formed by being subdivided into a plurality of parts, and that at least one of the louvers is A spacer is provided at one side end, and the plurality of subdivided louver units can be slid in the left-right direction by removing the spacer from the main body. (Function) Due to the groove formation, according to the present invention, the louver forming the air inlet and outlet is subdivided into a plurality of louver units, and these louver units can be adjusted in the left and right direction by removing the spacer from the main body. Since it can be slid to the top, when installing the main body of the device or performing wiring, etc., it is sufficient to remove only the necessary unit out of the multiple subdivided Ruher Uninotes. Even if it is deformed or broken [14],
All you need to do is replace the applicable Ruher Uninote.
This has the advantage of improving workability as a whole.

(Example) Hereinafter, preferred examples of the present invention will be described based on the drawings.

FIG. 1 shows an embodiment in which the present invention is applied to a natural convection type heater. This natural convection type heater supplies air near the radiation fins by energizing the heater to generate heat in the heater unit. The air is heated to produce an upward air current, and this upward air current sucks in cold air from the air inlet and blows out warm air from the air outlet.

As shown in Fig. 1, this natural convection type heater has a rear panel 1 made of temporary metal, a front panel 2, a roof 3 having a mesh part made of plastic resin, and a side cover 5 that covers both end surfaces of the main body housing. are doing. In addition, the louvers 3 with openings formed by mesonules are arranged in two rows (several pieces each) in the left-right direction (width direction) of the main body above and below the front panel 2, and the air outlet A is located in the louver row above the front panel 2. form,
The row of louvers below the front panel 2 forms an air suction port B.

The louver row is a louver unilateral structure in which the louver row forming the air outlet and the air intake port is subdivided.

A perspective view of the front panel 2 is shown in FIG. 3, and the front panel 2 also has a group of key holes 2-1 for fixing the Ruher Unisoto 3A3B... at approximately the center in the width direction of the front panel. It is set up so that the direction changes from left to right. Moreover, a square hole 2-2 for fixing the spacer 4 and a screw hole 2-3 for connecting and fixing the side cover 5 are provided at both ends of the key hole group.

As shown in FIG. 1 mentioned above, there are wall mounting holes 1-4 on the back side of the rear louver 1, and louvers 3-C and 3-D.
It is provided in an exposed position so that the screw can be tightened when removed. A square wall-mounting hole 1-5 into which a wall-mounting bracket 15 (FIG. 7), which will be described later, is inserted is provided at the top, and a square wall-mounting hole 1-5 into which a wall-mounting bracket 15 is inserted also at the bottom. 1-6 are provided.

Next, the structure of the subdivided louver unit 3 and spacer 4 will be explained in more detail.

is smaller than the width B,,Bz, and the height h. is smaller than the height H, and the height h2 is larger than the height H1 and smaller than the height H2. In addition, four dowels 3-4 are provided on the front back side of the louver uni-soto, as shown in FIG. 4 (Cl, (d)).

FIG. 5 shows the appearance of the spacer 4, which has an abbreviated shape when viewed from the side, similar to the Luher unit. A screw hole 4l is provided at the depth end of the short side at a position corresponding to the female screw 1-3 for fixing the spacer provided on the rear panel l. Further, at the lower end of the long side, a protrusion 4-2 is provided for coupling with a square hole 22 provided in the front bar 2 for fixing a spacer. The width dimension C of this spacer 4 is larger than the width B+, Bz of the key hole shown in the second part, and the width dimension C of the spacer 4 is larger than the width B+, Bz of the key hole shown in the second part.
The width and height dimensions of 2 are square holes 2-2 provided in the front bar 2.
is smaller than that of

Next, a method for removing the Ruher unit and spacer will be explained based on FIGS.

To remove the Luhr 3, it is first necessary to remove the spacer 4. To remove the spacer 4, as shown in Figure 6(a), loosen the spacer fixing screw l6 and remove the screw, then remove the spacer 4. The protrusion 4-2 provided in the square hole 2- of the front panel
Since it is inserted into the spacer 2, it can be removed from the main body by lifting the spacer 4 to a position where the protruding part is removed from the front panel as shown by the arrow, and then pulling it forward. Next, a method for removing the roofer 3 will be explained.

As mentioned above, the relationship between the Luher's claw dimension and the key hole dimension is that the large diameter B of the key hole and the Hz dimension part are the B of the claw part, respectively.
,,Since it is larger than the h2 dimension, the claw part can be removed from the baffle by pulling it, but the small diameter B.
．． H. In the dimension part, the H2 dimension of the claw is larger than the H1 dimension of the key hole, so when it is fixed to the main body, it will be caught on the panel at this part and will not come off.

Therefore, in order to remove the looper 3, the louver claws 1-2.
It is necessary to bring 3-3 to the large diameter dimension Bz, Hz part of the key hole. Also, the width dimension C of the spacer 40 is B+ of the key hole.
．． Since it is larger than the Bz dimension, if you remove the spacer according to the procedure shown in Figure 6 (a), you can move the roofer to the side where spacer 4 was attached in the direction shown by the arrow in Figure 6 (b). The louver claw can be brought to the large diameter B2, Hz dimension part of the key hole. In this position, as shown in Figure 6(C), pull the upper part of the louver toward you and insert the claw 3-2 of the louver into the oyster hole 1 of the rear panel.
-2, then lift the roofer and remove the claw 3-3 from the key hole 2-1 on the front panel to complete the removal of one roofer.

Furthermore, if you want to remove the next Ruher Unisoto, please refer to the 6th
All you have to do is repeat the steps shown in Figure 6 (b) → Figure 6 (C). Conversely, when attaching the removed louver uni-soto and spacer to the main body, repeat the steps shown in Figure 6 (Cl → (b) → (a)). It is best to assemble them in order.

In this embodiment, the keyholes 1-2 and 2-1 provided in the rear panel and the front panel have different directions on the left and right from approximately the center in the width direction of the panel, as explained in FIG. Furthermore, as explained in FIG. 1, since the louver units 3-3 at both ends have a mechanical feature in that one spacer 4 is provided at each end of the subdivided louver units 3- A. 3-B, 3-C and 3-D can be removed individually.

In other words, according to this embodiment, it is possible to remove only the roofer that is necessary for wall mounting work on the main body and electrical work on the terminal block part, without having to remove the entire front panel as in the conventional example. Become.

Next, we will briefly explain how to attach the main body of the device to the wall and how to perform electrical work.

Figure 7(a). (bl, (C) shows a method for mounting the main body on a wall, a perspective view of the wall mounting bracket, and a side view of the main body mounted on the wall.

In order to mount the main body on a wall, two wall mounting brackets 15 as shown in Fig. 7(B) are required, and the wall mounting brackets 15 have two missing parts for fixing the wall mounting brackets to the wall. Ji hole 15-
1. One female screw l5-2 for securely fixing the rear panel 1 and the wall mounting bracket 15, square holes 15 for wall mounting provided on the back and bottom of the rear panel, and square holes 1-6 for wall mounting. A folded portion 153.15-4 is provided which engages with.

To mount the main unit on the wall, first attach the wall mounting bracket l5.
Fix the book mounting bracket fixing screw 17 to the wall through the screw hole 15-1. Next, attach the main body to the wall as shown in Fig. 7 f.
), the bent part 15 of the wall mounting bracket
-3. 15-4, and wall mounting holes L-5 and square holes 1-6 provided on the rear pallet 2 to attach to the wall (hook it on the size bracket).

Next, after removing the blow-out side loopers 3-C and 3D of the main body according to the procedure explained in the method for removing the loopers, attach one main body fixing screw l8 from the front of the main body to the wall mounting hole 1-4 and the female screw 15-. Main body through 2 (rear paddle 1)
and fix the wall mounting bracket 15.

Finally, the Luhrer 3- removed for installing the body fixing screw l8
Once C and 3-D are assembled, the wall installation work for the main body is completed.

Next, we will explain the electrical and construction methods.

Figure 8 shows two device bodies connected and loopers 38 and 3-B.
This is a diagram showing the state in which the power supply wire and feed wiring work has been performed after removing the power supply wire.

When connecting two units in this way, two types of electrical work are required: one is wiring the power cable to the first unit, and the other is wiring work from the first unit to the second unit. First, we will explain the wiring work for the power supply wires.

(1,000 orders) No. 7, cut-out hole 1-, which was made in the area of the back failure.
Punch out one of 1 and pass two power wires through it.

(Step 2) Remove one luer unit 3-A (Fig. 1) on the side where the non-knockout hole 1-1 has been punched according to the luer removal method described above.

(Step III 3) Next, if you remove the C terminal cover 10 (Fig. 2), the terminals C and d of the terminal block 9 will be exposed.
Connect the two power wires passed in step 1 to d.

(Step 4) After attaching the terminal cover 10, assemble the Ruher Uninote 3-A.

Next, I will explain the transmission wiring work.

Steps for wiring work> (Hand 11111) Punch out the knockout holes 5-1 in the adjacent side covers 5 of the two connected main bodies.

(Step 2) Luhar Unisoto 3B (No. 1) of the first main unit
(Fig.) and the second main unit's Ruher Uninote 3-A (Fig. 1), and then remove both terminal covers 10.

(Hand 1 + lJj3) After connecting the two power cables to the terminals c and d of the terminal block of the first unit, pass the other side of the power cable through the hole 5-1 punched in step 1 and connect the terminals c and d of the second unit. Connect to.

(Step 1 4) After installing the terminal cable lO, assemble the cable connectors 3-A and 3-B.

As explained above, in this embodiment, a spacer 4 is provided next to the louver, and by simply removing this spacer 4 and removing one louver at both ends, wall mounting work and power cable wiring work can be completed. The terminal block is configured so that terminals c and d are in the louver position so that wiring work can be carried out.

However, Louhar is a suction of air. Since it has an opening with a menouche structure to form an air outlet, although the terminals c and d, which are live parts, are covered with a temporary terminal cover, there is no possibility that hands or wires, etc. It cannot be said that there is no risk of accidental electric shock if a person enters the device and touches a live part.

In order to eliminate such a risk of electric shock, in this embodiment, the subdivided Luher Uninotes 3-. A3-B also serves as a terminal cover for connecting the electrical connection part of the terminal block for electrical wiring.

FIG. 9 (al. (b)) shows the configuration of a Luher Unisoto which also serves as a terminal cover.

In this embodiment, a Cacher plate 19 made of a plastic resin, which is a separate part, is retrofitted to the louver uni-soto in order to cover the mesh opening. The Cacher plate 19 is a plate-shaped component made of a plastic resin such as a Haeclite plate, and its dimensions are approximately the length of the long side of the Luher 3, and it has four holes 191.

On the other hand, as explained in FIG. 4, the looper 3 is provided with four dowels 34 at positions corresponding to the four holes 19-1, so the cover plate 19 can be attached to the looper 3 through the holes. After assembling the dowel 19-1 to the dowel 3-4, the dowel 3-4 is thermally caulked using a processing method such as heat sealing.

In this way, using the Luhar Uni-no-T with the Kahar play eye 9 attached, the Ru-har Uni-no-L-3- of both ends of the main body is
When assembled in positions A and 3-B, the electrical connections of the terminal block will be completely sealed.

FIG. 10 is a side cross-sectional view of the assembled looper 12 with the cover plate 19 attached.

As in this example, if a Kaha plate is retrofitted only to the louver uni-so at the location where the terminal block is installed, the louver uni-so can be shared, and the mesh opening of the louver can be completely closed. Since it can be blinded, there is no risk of electric shock and it is safe. Further, it is also possible to omit the terminal cover provided inside.

In the above embodiment, the main body of the device is attached to two parts using wall mounting brackets.
We explained about the paceboard HIKU, which has terminal blocks on both sides of the heater unit so that power supply wiring work and feed wiring work can be done when the boards are connected and fixed to the wall, but if the room is small, There is no need to connect two heaters, and the main body of the heater may be fixed to a floor type using a stand instead of being fixed to a wall. In this case, since only the power supply wire work is required, the terminal block only needs to be installed on one side, and therefore the spacer only needs to be placed at one end of the main body.

Next, an embodiment of the type in which a spacer is provided only at one end of the looper will be described based on FIGS. 11 to 15.

In this embodiment, since only one terminal block is required for power cable work, the spacer 4 is provided only at one end of the louver 3, and the main body is fixed on the floor. It is. Note that the method for removing the roof and the spacer, the method for constructing the power supply wire, and the structure of the roof and the spacer are completely the same as those in the above-mentioned embodiment, and therefore, the explanation thereof will be omitted.

The floor stand 20 shown in FIG. 14 is provided with two screw holes 20-1 for screw fixing to the main body, and the rear panel of the upper main body is provided with a wall as shown in FIG. Instead of the mounting holes 1-4.1-5.1-6, there are stand name holes 20l. on the bottom of the rear panel. A female thread 1-7 for attaching the stand is provided correspondingly.

Fig. 12 shows an external view of the stand 20 placed on the floor, but the stand 20 can be installed with the stand mounting screw 21 through the screw hole 20-1 and the stand mounting female screw 1-7 without removing the roof. It can be fixed to the main body.

In other words, if it is placed on the floor and there is only one terminal block on one side, the only Luhr that needs to be removed from the main body during installation is the Luhr Uninote 3-A located at the terminal block position. This means that the spacer only needs to be provided at one end of the louver.

In addition, as shown in FIG. 15, Luher's claw 32.3-
Since the spacer 4 is only provided at one end of the keyhole group that engages with 3, there is no need to change the direction from the approximate center of the main body to the left and right. Arrangement (Effects of the Invention) As explained above, the present invention is characterized in that a meson-like louher forming an air inlet and an air outlet is divided into a plurality of small parts, and a spacer is provided at at least one end of the louher. By removing the spacer from the main body, the plurality of subdivided louver uninotes can be slid in the left-right direction, thereby providing the following effects.

(1) Since a spacer is provided next to the louver,
Simply remove the spacer and remove the small and light louver units divided into small pieces from the main body as many as necessary for construction.
Workability during construction is good as electrical work such as wall mounting of the main unit, power supply wiring, and feed wiring can be performed.

(2) Even if a child accidentally hits the device with a ball or kicks it and deforms it, the louver unit is divided into small parts and has a spacer, so you can easily use the louver unit with the device fixed to the wall. It is removable, and only the deformed Luhar Uninote needs to be replaced, reducing the cost of repair and replacement.

Furthermore, since it is easy to repair and replace, it is less likely that the deformation will deteriorate due to being left untreated until it becomes large.
