BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to an air conditioner capable of performing maintenance service inside an indoor unit from the outside of a wall having an indoor unit installed therein.

Conventionally, as an indoor unit of an air conditioner, for example, in order to mix negative ions into the air discharged to the room, there is an example in which a negative ion generator is provided in the air stream blown (for example, refer to Patent Document 1).

For example, when the negative ion generating unit is contaminated with dust, remove the blowing direction control panel by opening the makeup cover on the front surface, take out the discharge electrode of the negative ion generating unit, clean it, and return it to the same position. It is.

However, since the negative ion generating electrode is a component which has been subjected to high precision processing, a general non-expert cannot perform attachment removal, cleaning, or the like, and a service man who handles household electric equipment came and cleaned as described above.

Therefore, at the time of cleaning, the order client, which is a customer, must be at home at the scheduled time when the serviceman comes, and it is difficult to adjust the time in the double income family as in these days. Therefore, the cleaning cannot be performed in a proper period of time, however, it has been postponed in some cases and has been used in a state where the efficiency of the negative ion generator is deteriorated.

[Patent Document 1]

Japanese Patent Laid-Open No. 3-87531.

In addition to the negative ion generator, the air conditioner is regularly serviced or replaced, and there are filters for cleaning, ozone generator, deodorant, electrical components, and the like. This is very convenient, but conventional products can only receive such maintenance service from the indoor side. It is very convenient at the time of service activity that the electrical parts and the like also need to be replaced in one place so that they can be exchanged from the outside.

In order to clean such an air conditioner regularly, a serviceman may set the room at the orderer's home time, leave a key to the room, or open an opening larger than the indoor unit on the wall with the indoor unit in advance, and from this opening to the outdoor side for each indoor unit. After taking out and removing the front cover of the indoor unit, the blowing direction control panel, etc., for example, after removing the negative ion generating part (discharge electrode part), cleaning the discharge electrode part, etc., returning the indoor unit to the wall again. I was letting go.

Therefore, a serviceman unfamiliar with taking out the indoor unit may bend or damage the refrigerant pipe connecting the indoor unit and the outdoor unit. In addition, in order to prevent anyone other than the serviceman from entering the room from the outside, it is necessary to prevent the indoor unit from being easily removed, and it is necessary to attach a door with a key to an opening such as a wall. Was complicated and costly.

Therefore, there is a demand for a simple and reliable short time replacement of parts, cleaning (cleaning), and the like from the outside even if a service man does not enter an empty house. In addition, the air conditioner disclosed in Patent Document 1 was not able to perform parts replacement, cleaning (cleaning), etc. from the outside.

An object of the present invention is to allow maintenance services such as parts replacement and cleaning in an indoor unit to be performed from the outside of the wall where the indoor unit is installed.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention has the opening part for maintenance service in the back of an indoor unit, and is a position which can be repaired through the through hole of the wall member which attaches the said indoor unit, and the back opening of the said indoor unit, and the maintenance service target part of the indoor unit. It is characterized in that arranged in.

According to the present invention, since the inside of the indoor unit installed on the inside of the wall from the outside can be repaired from the outside of the wall, various maintenance services can be performed as needed even when the owner who installed the indoor unit is absent.

For example, the filter of the indoor unit can be replaced or cleaned, the electric parts inside the indoor unit can be replaced or cleaned, the inside of the indoor unit can be easily cleaned, and the like. In addition, by adding a certain property to the blowing air of the indoor unit, there are fragrances that provide a fragrance such as negative ions and cypress, and a predetermined treatment is performed on the blowing air to remove odor and sterilize. Etc., and it becomes possible to service these on a regular basis.

In the outline of the embodiment of the present invention, an opening (duct 10) is formed on the back of the indoor unit so that various maintenance services can be frequently performed from the outside to the indoor unit 1 of the air conditioner in FIG. (10) and through-holes (ducts 12) formed in the wall member for installing the indoor unit, so that parts can be replaced, the indoor unit can be cleaned, or a part that adds added value to the blown air can be provided. will be.

Hereinafter, the repair of the negative ion generator 9 (FIG. 1) mainly installed inside the indoor unit, the replacement or cleaning of the filter (FIG. 10) installed in the indoor unit, or the structure of the through-hole of the wall member and the rear opening of the indoor unit. Although the present invention is described, the present invention is not limited thereto, and the present invention is also applicable to maintenance parts such as improving various parts of the indoor unit or the quality of the indoor unit blown air.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described with reference to drawings. Fig. 1 shows an indoor unit having a negative ion generator therein. The housing of the indoor unit 1 of the air conditioner is composed of a makeup cover 2. The makeup cover 2 is provided with an intake port 2a for indoor air, and a heat exchanger 3 is provided adjacent to the intake port 2a to cool or warm the room air, and the intake port 2a is provided by the fan 4. The air sucked in the air) is blown into the room from the blowout port 5 via the heat exchanger 3. In this example, the fan 4 uses a perfusion fan.

The blowout port 5 has a vertical blowing direction control panel 6 that controls the blowing direction up and down, and controls the flow direction of the air blown from the flow-through fan 4 in the vertical direction. Moreover, the blow-out direction of the air blown from the flow-through fan 4 with the left-right blowing direction control board 7 is controlled to the left-right direction (horizontal direction). Moreover, the back side casing 8 is provided in the back side inside an indoor unit, and comprises the internal space.

In this example, the negative ion generator 9 is disposed on the front flow side of the outlet 5. 1 to 9, the negative ion generator 9 has a discharge electrode 9a for generating negative ions or a discharge electrode so as not to touch the discharge electrode 9a. The electrode cover slit 9c etc. provided in the cover 9b and the electrode protective cover 9b to protect are provided.

In this embodiment, the opening part 11a was formed in the back plate 11 of the air conditioner, and the service duct 10 was provided between this back opening part 11a and the back side casing 8. In addition, the wall duct 12 is inserted into the through hole formed in the wall 13 with the indoor unit in accordance with the rear opening 11a, and the wall duct 12 and the service duct 10 are connected.

By doing in this way, when cleaning the discharge electrode 9a from outside, the inside of the duct 12 and 10 can pass the cleaning rod and the brush 14 (FIG. 2).

In this example, as shown in FIG. 1, since it is connected to the through-holes (ducts 12 and 10) in a straight line from the outside to the discharge electrode 9a of the negative ion generator of the air conditioner, for example, the discharge electrode 9a. Even when the dust is attached to the room and the performance deteriorates, the serviceman can come in and clean the brush 14 or the like for cleaning the discharge electrode 9a in the duct 10.

At that time, even when the owner is absent, since it can be cleaned directly from the outside, it is not necessary to be in a house after consultation in advance, and a service man can also serve at any time, so that efficient service activities can be performed. For this purpose, the attachment direction or the like of the discharge electrode may be set in a direction that is easy to clean.

FIG. 3 is a method using a socket 15 capable of inserting and drawing the power supply connection portion of the discharge electrode portion 9 to facilitate cleaning of the discharge electrode portion 9 built in the indoor unit 1 from outside. Thus, the insertion and drawing directions are set in the axial direction of the wall duct 12 and the service duct 10.

As also shown in Fig. 4, the portion 16 (metal fittings, etc.) bited by the socket male portion 15a (discharge electrode side) is attached to the distal end of the rod inserted from the duct 10, and the discharge electrode 9a is first applied. The socket male portion 15a with the lead is drawn out from the socket female portion 15b (the power supply side), passes through the service duct 10, and is cleaned while looking at the discharge electrode 9a in the open air. It returns to the socket female part 15b via the duct 10.

In this case, as shown in Fig. 4, the front end of the discharge electrode 9a faces the rear surface of the indoor unit, and the slit 15a of the socket 15, which also serves as an electrode protective cover, is placed up and down. In addition, it is easy to insert and exits between the slits 15a of the socket 15 serving as a protective cover of the discharge electrode without interrupting the flow of the cooling air from the perfusion fan 4 by the socket 15. Therefore, many discharged negative ions can be applied to the air stream.

5, 6 (cross section A-A in FIG. 5), and FIG. 7 show other mounting examples of the negative ion generator. In order to facilitate cleaning of the discharge electrode portion 9 built in the indoor unit 1 from the outside, a rail is provided between the discharge electrode portion 9 which generates negative ions and the outdoor opening 12a of the duct 12 in the wall. (17), the discharge electrode portion 9 is mounted on the slider 19 so that the discharge electrode portion 9 can move freely on the rail 17. As shown in FIG.

Therefore, when cleaning the discharge electrode part 9 from the outside, the discharge electrode 9a is easily removed from the outside by pulling the slider 19 equipped with the discharge electrode part 9 to the back direction, ie, the outer direction of the wall. can do. Therefore, reliable cleaning (cleaning) can be performed in a short time. After cleaning, the discharge electrode 9a can be reliably cleaned by returning the rail 17 to its original position without entering or leaving the house even when the owner is absent.

8 is another example of mounting the negative ion generator, and similarly to the above example, in order to facilitate the cleaning of the discharge electrode portion 9 built in the indoor unit 1 from the outside, the wires to the discharge electrode portion 9 are removed. By using the flexible wire 20, the discharge electrode 9 inside the indoor unit can move freely to the rear surface. Therefore, after removing the discharge electrode part 9 from the fixed part, and taking out from the back opening 12a via the back duct 10, it is not necessary to connect or disconnect a lead wire (wire), The discharge electrode portion 9 can be cleaned while checking.

9 is another example of mounting of a negative ion generator. To easily clean the discharge electrode portion 9, a negative ion generating device (discharge electrode portion 9) is attached to the tip portion 21a of the supporting rod 21, and the supporting rod 21 is attached to the indoor unit 1. The discharge electrode portion 9 is provided in the cooling air discharged from the hole (duct 12) opened in the wall in which is installed, and discharged by the flow-through fan 4.

The other end 21b of the supporting rod 21 is screwed in the vicinity of the hole opened in the wall where the indoor unit is installed, and the screw is removed to freely remove or insert the negative ion generating device 9 from the outdoor side. The cleaning of the negative ion generating device 9 can be performed reliably and easily while visually seeing the cleaning of the negative ion generating device 9 outdoors.

Next, with reference to FIG. 10 and below, the example which performs maintenance services, such as filter replacement of an indoor unit, from the exterior of the wall which installed the indoor unit of an air conditioner is demonstrated. In this example, the indoor dust removal filter 22 attached to the suction port 2a side of the indoor unit 1 is made into a belt shape, and one end is wound around the core 22a, and the other end is wound around the other core 22b. Made it possible. In this manner, the contaminated side is wound up and a new side emerges, and if necessary, the reverse side can be reversed.

In addition, since the cores at both ends are designed to be taken out from the outlets 25 and 26 of the left and right cores open to the indoor unit rear and the wall, or to be attached after insertion, the serviceman filters the filter at the time when the winding is advanced and becomes the last side. When cleaning (22), the wound filter is loosened, and the filter taken out and wound up for each core 22b is taken out of the core 22b, and the attached dust or the like is removed with a brush or the like and cleaned.

After the cleaning is completed, the filter is wound on the core 22b and returned to its original state. Then, the last face of the filter is wound on the core 22a. Then, the core 22a is taken out of the wall to take out the contaminated surface for cleaning. do. After cleaning, it winds up again to the core 22a and returns to it. Subsequently, the two cores are properly rotated to set the first face. This can be used again. In addition, since these operations can be performed only outdoors, service activities of filter cleaning can be performed even when the owner is absent.

In addition, the attachment structures of the cores 22a and 22b are as shown in Figs. 11 (viewpoint AA in Fig. 10) and 12 (section BB in Fig. 10), and the upper shaft center length Lu and the bearing ( The depth Du of 22c is made longer than the lower axis length Ld, and the clearance Su between the upper bearing surface and the upper end of the filter 22 is made larger than the lower axis length Ld.

Thereby, by moving upwards for every filter 22 wound around the shaft core, and pulling forward, the shaft core which winds up the filter 22 by taking out the hole of the lower bearing surface 22d can be taken out, The filter is loosened, decontaminated, and then wound up. On the contrary, the lower shaft is returned to the lower bearing hole 22d while the upper shaft is inserted into the hole of the upper bearing 22c. By winding up on each shaft, the filter 22 is provided in the suction surface 2a without loosening.

Next, another example for cleaning the suction side filter of the indoor unit will be described with reference to FIGS. 13 and 14. The filter 22 of this example is formed in one strip as shown in Fig. 13A, and as shown in Fig. 13B, the hook portion 22c is formed at the left end of the filter. 22 d of holes which receive the left hook of another filter are provided in the right end part.

As shown in Fig. 13A, although the filter 22 is attached to the indoor unit in the shipped state, when the filter 22 contaminated during use is cleaned, the filter 22 can be cleaned on the outside side. Spaces respectively accommodating both ends are provided on the left and right from the front face with the filter to the rear face of the indoor unit. In addition, the opening holes 25 and 26 are open to the wall 13 to which the indoor unit is attached to the space.

In this configuration, as shown in Fig. 13B, the suction surface moves when the left side of the filter 22 is stretched. In this case, another new filter is prepared, and the hook portion 22c of the new filter 22 shown on the right side of the figure is provided with a hook receiving hole 22d of the old filter (contaminated filter 22 currently in use). Hang on.

In this way, when the old filter (left) is drawn out, a new filter (right) is drawn in, and when the hook receiving hole 22d of the old filter exits from the opening hole 26, the new filter covers the suction surface. Can be replaced with a new filter 22 that is not attached.

In addition, as shown in Fig. 14A, the hooks 32c are provided at both ends of the tape-shaped article (tape 32) instead of the new filter 22, so that a new expensive filter 22 is not separately prepared. And the hook receiving hole 32d are provided, and when cleaning the filter 22 currently in use, the filter 32 is joined to the hook receiving hole 32d of the filter 22 before taking out, and then the filter When only (22) is taken out and the cleaning is completed, the tape 32 may be rewound and the filter 22 may be positioned on the suction side of the indoor unit again. Thus, the same effect can be obtained.

In addition, as shown in Fig. 14B, the same effect can be achieved by using only the frame 33 of the filter 22 instead of the tape 32 and connecting the frame 33 to the filter 22 to use it. I can raise it. Since these methods can be exchanged only on the outdoor side, service activities can be performed even when the owner is absent as in the above example.

Next, Fig. 15 shows an example of the indoor unit attachment structure in the present invention. This example shows an example in which the indoor unit 1 is attached to the outer wall 28 via the attachment member 27. The opening 11a for a service is provided in the back plate 11 which comprises the indoor unit 1 so that the component which needs replacement by the component of the indoor unit 1 of an air conditioner can be replaced from the outside side, The opening 27a facing the opening 11a is also provided in the attachment member 27 to which the indoor unit 1 is attached, and is also placed outdoors at the position opposite to the outer wall 28 fixing the attachment member 27. A through hole 28a is provided. By doing in this way, a component can be removed and attached from the opening 28a of the outer wall 28, and various services are possible from the outdoors.

16 shows an example in which the cover 23 is attached to the outer wall duct 12. In order to clean the indoor unit 1 of the air conditioner from the outside, when the duct 12 in the wall is provided on the wall, to prevent the intrusion of the rain from the opening of the duct 12, and at the time of service such as cleaning. In addition, the cover 23 which closes the opening part was attached so that the discharge electrode part 9 might not be contacted from the outside, for example, so that it might not playfully intentionally.

17 and 18 show an example in which the key 24 is attached so that it cannot be removed except when the cover 23 is required. The structure of the key 24 will be described with reference to FIGS. 17 and 18.

As shown in Fig. 17, a stopper 23a is provided inside the cover 23, and the lower end of the cover 23 is hooked (key), and the latch 29 has a tip 23b of the stopper 23a. Upon contact, the latch 29 compresses the coil spring 30 which is in contact with the lower end with the support point 29a as the rotational axis and lowers it once, but after the tip 23b of the stopper 23a passes, By the reaction force, the latch 29 engages with the hook portion 23b so that the latch 29 does not return even when the cover is rewound. In other words, the cover 23 is filled with the key.

Next, as shown in Fig. 18, when releasing the key, the coil spring 30 is also lowered by loosening and lowering the screw 31 that is being pushed up while compressing the coil spring 30 from below. ) Is removed from the hook portion 23b of the stopper 23a, so that the cover 23 can be pulled off from the outside.

Therefore, knowing that a service man comes beforehand, when the owner is absent, the screw 31 can be lowered indoors and the key can be unlocked. When the owner returns home, if the service is finished, turn the screw 31 again to raise the coil spring 30, and when the latch 29 is acted on the stopper 23a, the key is locked and the cover 23 is outside. It cannot be opened.

In addition, since the outside air does not penetrate by attaching the cover, the efficiency of the air conditioner is not deteriorated. Even if a strong wind blows through the opening due to a typhoon or the like, it does not affect the airflow discharged from the indoor unit, and stable discharge flow can be obtained.

Hereinafter, the effect of embodiment of this invention is demonstrated. As described in detail above, since the connection is connected to the discharge electrode portion in which the indoor unit is attached to the discharge electrode portion generating negative ions, for example, in a straight line, the discharge electrode portion can be cleaned outdoors. Can be.

Moreover, when attaching a discharge electrode part, the discharge electrode part was made into a socket type, the insertion direction of a socket was made into the back through-hole direction of an indoor unit, and the slit direction of a protective cover was made into the up-down direction, so insertion of a discharge electrode part is a through hole of a back part. Since the discharge electrode portion squeezing rod (attached to the bracket) inserted into the discharge electrode can be easily used, and the air flow to the discharge electrode is not impeded, a large amount of air is likely to flow, and a large amount of negative ions are contained in the discharge air. Can be.

In addition, since the discharge electrode portion inside the indoor unit and the air opening of the through duct are connected by a rail, and the discharge electrode is mounted on the rail to be movable, the discharge electrode portion can be pulled out from the outside, and the discharge electrode portion is visually observed. Since it can be seen well, the discharge electrode can be reliably cleaned.

In another example, since the electric wire used as the power source of the discharge electrode part is made of a flexible material, the discharge electrode inside the indoor unit can be freely moved to the rear opening, which eliminates the need for disconnecting or connecting the power supply and facilitates service activities. Work efficiency can be improved.

In addition, since the negative ion generator was attached to the tip of the supporting rod and the other end of the supporting rod was screwed from the outside near the opening hole of the wall where the indoor unit is installed, the negative ion generator was freely taken out from the outdoor side by loosening the fixing screw. You can clean it. As a result, the serviceman can clean the service while the owner is absent, so that the service can be guaranteed.

In addition, by attaching a cover to the opening of the outdoor wall and attaching a key, there is no fear of rain, and no strong wind blows into the indoor unit through the through pipe, so that the discharged airflow is not scattered and a stable state can be obtained. have. Moreover, since a key is attached, it does not come in contact with a discharge electrode part etc. when it is not necessary from an outdoor side, and also it is effective also in crime prevention.

In addition, the parts such as the filter requiring service are arranged to be able to take out or attach the parts from the back so that the parts can be serviced from the back of the indoor unit, and the through holes in the back of the indoor unit, the indoor unit mounting plate and the wall Since the owner can receive the service even when the owner is absent, efficient service activities are possible.

In the above, the repair service for the negative ion generator, the filter, and the like has been mainly described, but according to the present invention, other electric parts inside the indoor unit can also be subjected to the service. For example, the air blown out from the indoor unit to the room may be targeted for maintenance service. As an example, a component that adds the aroma of cypress to the blown air can be exchanged and installed regularly from the outside even when the owner is absent, similarly to a negative ion generator.

Similarly, ozone generators, odor removers, sterilizers, and the like can be installed and replaced from the inside of the indoor unit. In addition, it is possible to perform a regular cleaning service, for example, by inserting a previous thin vacuum cleaner from the outside to suck in the dust inside the indoor unit, and keep the indoor unit clean at all times.

Here, Fig. 19 shows a comparative example of an indoor unit having a negative ion generator. In order to mix negative ions into the air discharged into the room, the discharge electrode 109 of negative ion generation is provided in the airflow passing through the heat exchanger 103 blown by the perfusion fan 104.

For example, when the negative ion generator (discharge electrode 109) is contaminated by dust and cleaned, the makeup cover 102 of the front face is opened to remove the blowing direction control panels 106 and 107 and then the negative ion generator The tip (discharge electrode 109) is taken out, cleaned and returned to the same position again.

However, since the negative ion generating unit (discharge electrode 109) is a component which has been subjected to high precision processing, a serviceman who handles household electrical equipment comes to remove the cover 102 of the indoor unit, and the blowing direction control panel 106, 107. ), The discharge electrode 100 was taken out and cleaned. Therefore, it was very inconvenient to be at home when the serviceman came. In addition, cleaning cannot be performed in an appropriate period, so that the use of the negative ion generator in a deteriorated state is often used.

As described above, according to the present invention, an opening for maintenance service is provided on the back of the indoor unit, and through such openings and through-holes formed in the wall to which the indoor unit is installed, services such as replacement and cleaning of parts inside the indoor unit can be performed from the outside. As a result, regular maintenance service can be provided even if the owner is absent.
