Description

  The present invention relates to an electrical product generator that generates electrical products such as ozone and negative ions. In particular, in a ceiling-mounted electrical product generator, maintenance such as replacement of consumable parts can be easily performed. Moreover, the present invention relates to an electrical product generator that can be reliably performed in a short time.

  There has been proposed a configuration in which an ozone generator intended to obtain a deodorizing effect due to the oxidizing power of ozone can be installed on the ceiling. It is known that installing the ozone generator on the ceiling part can effectively utilize the characteristic that ozone is heavier than air, and is extremely effective in diffusing into the entire space.

  In addition, it is possible to cover a wide area by installing a negative ion generator, which is used as a means to counteract static electricity generated by friction with carpets laid on indoor floors and household appliances, etc. on the ceiling. is there.

  The problem with the ozone or negative ion generator configured to be installed on the ceiling in this way is that it is difficult to perform maintenance work because the installation location is high.

  In particular, in the ozone generator, nitrate is deposited together with dust adhering to the ozone electrode portion, which prevents contact with the air necessary for ozone generation, and the amount of ozone generated decreases, so maintenance is required. . Also, when negative ions are generated, corona discharge is generated by applying a negative high voltage direct current to the discharge electrode with the tip sharply sharpened. Since the capacity is reduced, maintenance such as replacement of the discharge electrode is required. In addition, the fan for sending air used accompanying these is a component that is liable to cause a failure such as a rotation stop due to a malfunction of a rotation mechanism such as a fan motor or a bearing, and requires regular maintenance.

  In order to maintain the high quality of ozone and negative ion generators having such product characteristics, maintenance such as replacement of consumable parts at least once a year is required. However, as described above, the maintenance of the ceiling-mounted type requires the operator to work upward at a high place, which forces the worker to be very tired, and this can be done easily and reliably in a short time. The challenge was how to do it.

  By the way, in order to facilitate maintenance, a conventional ozone generator has been proposed in which a discharge electrode is detachably provided so that a discharge electrode or the like that easily adheres to dirt can be cleaned. (For example, refer to Patent Document 1).

  Also, a conventional ozone generator has been proposed in which a cylindrical electrode is housed in a box-shaped cartridge, and this cartridge is detachably attached to a mounting opening provided on the upper surface of the case. Yes. As described above, the cylindrical electrode is housed in the cartridge so as to be detachable, so that fine dust and dust collected on the electrode can be more easily cleaned (see, for example, Patent Document 2). .

  Furthermore, in conventional lighting fixtures, a mounting adapter that is detachably attached to a hook ceiling attached to the ceiling surface, a lighting fixture body that is detachably attached to the mounting adapter, and a detachable attachment on the lower surface side of the lighting fixture body There has been proposed a lighting apparatus having a negative ion generator that can be freely attached. In this luminaire, the negative ion generator is removed from the luminaire main body so that maintenance can be performed (for example, see Patent Document 3).

JP-A-8-50984 Japanese Patent Laid-Open No. 10-291807 JP 2004-146335 A

  In the conventional ozone generator and negative ion generator described above, in order to facilitate maintenance, the discharge electrode itself can be replaced, or the discharge electrode is housed in a cartridge, and the cartridge is placed in the case. There have been proposed ones configured to be detachable from an attachment port provided on the upper surface, and further configured to be able to attach / detach the negative ion generator itself from a lighting fixture attached to the ceiling. However, no proposal has been made that can easily and reliably perform maintenance work at a high place on an ozone or negative ion generator of the type installed directly on the ceiling.

  The present invention is intended to solve the problems of the conventional electrical product generator of the type installed directly on the ceiling, and in particular, maintenance work at a high place can be performed easily and in a short time. An object of the present invention is to realize an electrical product generator that can be reliably performed.

  In order to achieve the above object, the present invention provides a power supply unit and a control circuit unit in a ceiling-mounted electrical product generator that generates electrical products such as ozone and negative ions and discharges them indoors. And an apparatus main body provided with a ceiling mounting mechanism, an electric product generator, and a fan for sending out the electric product generated by the electric product generator to the outside of the apparatus main body. A cassette unit configured to be detachably loaded, and when the cassette unit is loaded into the apparatus main body, the cassette unit and the apparatus main body are electrically connected, and the cassette unit is mechanically moved into the apparatus main body. An electrical connector having a function of temporarily fixing, and a cover member that closes the opening of the apparatus main body and supports the temporarily fixed cassette unit are provided.

  Further, it is preferable that a dust removal filter having a cutout portion that matches the outer shape of the cassette unit is suspended by being fitted to the outer periphery of the cassette unit and disposed in the air flow passage on the air intake side.

  Further, the cover member is provided with an air discharge port formed to support the temporarily fixed cassette unit and to be connected to the air delivery side of the cassette unit, and an air intake port formed at the outer peripheral portion of the air discharge port. It is effective.

  The electrical product generator of the present invention configured as described above can provide an electrical product generator that can perform maintenance work at high places easily and reliably in a short time.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. FIG. 1 shows an embodiment of an electrical product generator according to the present invention, and is a cross-sectional side view in which a main part showing a state in which the electrical product generator is installed on a ceiling portion is cut away. 2 is an exploded perspective view of the electrical product generator, and FIG. 3 is a perspective view of a main part for explaining the process of attaching the cover member to the main body case of the electrical product generator.

  In the figure, reference numeral 1 denotes a ceiling-mounted electric product generator main body that generates ozone and negative ions, and at least inside a cylindrical main body case 11 made of a resin material provided with a flange 12 on the outer periphery of the lower end. A power supply unit 2 fed from an external power source and a control circuit unit 3 for controlling the apparatus are provided.

  The main body case 11 is configured to be easily attached to the ceiling member 4. As a method of attaching the main body case 11 to the ceiling member 4, for example, a cylindrical portion of the main body case 11 is fitted into an attachment hole 41 provided in the ceiling member 4 so as to protrude to the back side of the ceiling member 4. The flange 12 is brought into contact with the surface side of the ceiling member 4. In this state, the ceiling member 4 is sandwiched between the flange 12 by using a well-known ceiling mounting mechanism (not shown) provided in the body case 11, and the body case 11 is fixed to the ceiling member 4. is doing.

  A cassette unit 5 accommodates a fan 6 that sends air and an electrical product generator 7 that generates ozone, negative ions, and the like. The cassette unit 5 is configured to be detachably loaded into the main body case 11 through an opening 13 provided on the flange 12 side of the main body case 11. Furthermore, an electrical connector 8 is provided on the upper portion of the cassette unit 5 so as to be electrically connected to a high voltage generation unit of the power supply unit 2 and a fan power supply unit.

  The electrical connector 8 has a female terminal 81 attached to the case body 11 side, and the other male terminal 82 attached to the cassette unit 5 side, and is housed in an integral housing. In addition, the electrical connector 8 is simply held in connection with terminal contact friction, and has a structure without a mechanical locking mechanism.

  Therefore, the cassette unit 5 is mechanically temporarily fixed in the main body case 11 by electrical connection of the electric connector 8, and can be easily detached from the main body case 11, but in this state, The main body case 11 may fall off.

  Therefore, in the present invention, as shown in FIG. 3, the outer peripheral edge of the cover member 9 made of a resin material formed in a disc shape by forming a notch 14 in the outer peripheral edge of the flange 12 of the main body case 11. The cover member 9 closes the opening 13 of the main body case 11 and is securely attached to the main body case 11 by rotating the cover member 9 horizontally about 10 degrees. It is configured to be fixed.

  As described above, when the cover member 9 is fixed to the main body case 11, the peripheral wall 93 formed by projecting upward so as to surround the air exhaust port 92 provided at the substantially central portion thereof is connected to the lower end portion of the cassette unit 5. Thus, the gap is eliminated, the air exhaust passage is configured, the lower end portion of the cassette unit 5 is supported, and the cassette unit 5 can be securely mounted in the main body case 11. As a result, it is possible to prevent the cassette unit 5 from falling off without using any screwing or the like, which is a troublesome operation performed at a high place.

  Also, when performing maintenance on the electrical product generator configured as described above, first, the hook 91 is cut by rotating it horizontally about 10 degrees in the direction opposite to when the cover member 9 is mounted and fixed. When the cover member 9 is pulled down after being moved to the position of the notch portion 14, the hook 91 is lowered through the notch portion 14, and the cover member 9 can be removed from the main body case 11.

  The removal of the cover member 9 releases the support of the cassette unit 5 by the peripheral wall 93 of the cover member 9, but the cassette unit 5 is maintained in a mechanical temporarily fixed state by the terminal contact friction of the electrical connector 8. Therefore, even if the cover member 9 is removed, the cassette unit 5 does not fall immediately. Therefore, after the cover member 9 is removed, the cassette unit 5 is pulled down to release the connection state with the electrical connector 8, thereby releasing the electrical and mechanical connection state of the cassette unit 5. Without being dropped from the case 11, it can be easily removed and maintenance can be performed.

  Also, the cassette unit 5 removed from the main body case 11 can be removed from the cassette unit 5 and the electrical connector 8 simply by removing the fan 6 and the electrical product generator 7 used so far and replacing them with new ones. It can be reused as it is, and maintenance costs can be reduced and resources can be used effectively.

  In the electrical product generator configured as described above, in order to stably generate the electrical product, dust is obstructed and the electrical product generator 7 contained in the cassette unit 5 is placed in front of the electrical product generator 7. It is desirable to provide a dust removal filter 10.

  Therefore, in the electrical product generator of the present invention, as shown in FIG. 1, the air taken into the cassette unit 5 through the opening 51 formed in the upper part of the cassette unit 5 together with the electrical product is covered with the cover member 9. Therefore, the dust removal filter 10 is disposed at a position before the opening 51 of the cassette unit 5, that is, at the outer peripheral portion of the cover member 9. And an air flow path A formed between the opening 51 of the cassette unit 5.

  The dust removal filter 10 disposed in the air flow path A has a cutout portion 10 a that matches the outer shape of the cassette unit 5, and a plurality of cutout portions 10 a provided on a part of the outer wall surface of the cassette unit 5. The projection 52 is suspended and arranged.

  By configuring the dust removal filter 10 as described above, when the cassette unit 5 is removed from the main body case 11 during maintenance, it can be removed at the same time, and the dust removal filter 10 can be easily replaced. It can be done in a short time.

  The dust removal filter 10 has a planar rigidity, and the projection 10a provided on the cassette unit 5 has an outer peripheral portion of the dust removal filter 10 on the lower surface side of the flange 12 when the dust removal filter 10 is suspended. The outer peripheral portion of the dust removing filter 10 is brought into close contact with the lower surface of the flange 12 by the suction effect of the fan 6 and the function as a filter can be ensured. When the dust removal filter 10 is a soft material having no rigidity, the dust removal filter 10 is formed so as to reach the lower surface of the flange 12 after increasing the number of protrusions 52, and the dust removal filter 10 is sandwiched between the lower portions of the flange 12. By adopting a structure, the same effect can be obtained.

  It is sectional drawing side view which notched the principal part which shows the state which installed the electrical product generator concerning this invention in the ceiling part.   It is a disassembled perspective view of the electrical product generator which concerns on this invention.   It is a principal part perspective view for demonstrating the process in which a cover member is attached to the main body case of the electrical product generator which concerns on this invention.
