(1) Overall Configuration Hereinafter, an air cleaner will be described with reference to the drawings as an example of an electrical apparatus according to an embodiment of the present invention. The external appearance of the air cleaner 1 seen from the front left diagonal is shown by FIG. FIG. 2 shows the internal structure of the lower part of the air purifier 1.

  The air cleaner 1 includes a front panel 11, a side panel 12, a top panel 13 and an external suction grill 15. The suction port 21 is covered with an external suction grill 15 configured by arranging grids so as to allow ventilation. A pre-filter 22 for removing relatively large dust is attached to the suction port 21. The pre-filter 22 has, for example, a net in which polypropylene yarn is stretched and a frame that supports the net. Indoor air is sucked into the air purifier 1 from the suction port 21 in the direction of the arrow AR1. An external suction grill 15, a resin case assembly 31 and an upper frame 32 are fitted into the side panel 12. Although not shown, an air outlet is provided on the top surface of the air cleaner 1. The top panel 13 is provided with a blowing grill (not shown) configured with a grid. The air outlet is covered with an air outlet grill so as to allow ventilation. The airflow blown out from the blowout port is blown out in the direction directly above the air cleaner 1 as indicated by an arrow AR2.

  Moreover, the air cleaner 1 is provided with the HEPA filter 25, the deodorizing filter 26, and the sirocco fan 90 in the inside, as FIG. 2 shows. The sirocco fan 90 is installed at the bottom of the air cleaner 1. The sirocco fan 90 generates an airflow in the direction indicated by the arrows AR1 and AR2. The HEPA filter 25 and the deodorizing filter 26 are provided above the sirocco fan 90. All the airflow sucked from the suction port 21 by the sirocco fan 90, passing through the prefilter 22 and blown upward passes through the HEPA filter 25 and the deodorizing filter 26 in order. The airflow that has passed through the HEPA filter 25 and the deodorizing filter 26 and is purified is blown out from the air outlet at the top of the air cleaner 1.

  A streamer discharge unit 5 is installed upstream of the HEPA filter 25. The streamer discharge unit 5 can generate a streamer discharge, and can generate active species by the streamer discharge. The active species generated by the streamer discharge unit 5 is supplied to the air sucked into the HEPA filter 25.

  The HEPA filter 25 is a pleated filter, and can remove very fine dust that cannot be collected by the pre-filter 22. For example, a fine particulate material such as so-called PM2.5 can be captured.

  The deodorizing filter 26 is configured to include, for example, activated carbon, and is configured to be able to adsorb indoor air pollutants such as odor components, exhaust gas, and formaldehyde from the air that has passed through the HEPA filter 25. ing. Some of the odor components, exhaust gases, and indoor air pollutants adsorbed on the deodorizing filter 26 are not easily decomposed naturally. The active species supplied from the streamer discharge unit 5 has a function of decomposing odor components adsorbed on the deodorizing filter 26. The deodorizing filter 26 may carry a catalyst for enhancing the decomposition function by active species. Examples of such a catalyst include a manganese-based catalyst and a noble metal-based catalyst.

  The deodorizing filter 26 is supported by a frame body in the resin case assembly 31. By pulling out the resin case assembly 31, the deodorizing filter 26 can be taken out and the deodorizing filter 26 can be maintained. Moreover, the air cleaner 1 is comprised so that the HEPA filter 25 arrange | positioned under the deodorizing filter 26 can be taken out by removing the resin case assembly 31. FIG.

(2) Detailed configuration (2-1) Streamer discharge unit 5
When the external suction grill 15 and the prefilter 22 are removed and the protective lid 17 (see FIG. 6) is further removed, the streamer discharge unit 5 having a substantially rectangular parallelepiped shape shown in FIG. 3 is exposed. The hands shown in FIG. 3 are raising the first sheet cover 61 and the second sheet cover 62 that cover the outer side of the streamer discharge unit 5.

  As shown in FIG. 4, an internal suction grill 16, a first seat cover 61, a second seat cover 62, and a wire harness 70 with a connector are disposed around the streamer discharge unit 5. The streamer discharge unit 5 is attached to a unit storage portion 18 provided on the upper portion of the internal suction grill 16. The internal suction grill 16 is fixed to the main body 10 of the air cleaner 1.

  First, in order to describe the streamer discharge unit 5, a state where the streamer discharge unit 5 is attached to the unit housing portion 18 of the internal suction grill 16 and the wire harness 70 with a connector is connected is shown in FIG. 6, 7, 8, and 9 show the main body 10 of the air purifier 1 with the prefilter 22 removed and the first seat cover 61 and the second seat cover 62 removed. These states shown in FIGS. 5 to 9 are states for explanation, and the air purifier 1 as an actual product does not take these states.

  As shown in FIG. 5, the connector 71 of the wire harness 70 is inserted into the streamer discharge unit 5 attached to the internal suction grille 16 in the direction of the airflow sucked into the internal suction grille 16. The streamer discharge unit 5 is a discharge device that generates a streamer discharge that is a kind of plasma discharge. Through this wire harness 70, a high voltage for generating streamer discharge is supplied. The streamer discharge unit 5 generates active species (free radicals or free radicals) by streamer discharge, and supplies the active species upstream of the HEPA filter 25 and the deodorizing filter 26.

  Since a high voltage is applied to the streamer discharge unit 5, for the purpose of improving safety, as shown in FIG. 6, a protective lid 17 is attached so that the streamer discharge unit 5 is not exposed to the outside. A pre-filter 22 and an external suction grill 15 are further attached to the outside of the protective lid 17, and the protective lid 17 is removed and the streamer discharge unit 5 is exposed to the outside while the air cleaner 1 is in operation. Is prevented.

  When the streamer discharge unit 5 is replaced or maintained, if the protective lid 17 is removed, the streamer discharge unit 5 to which the wire harness 70 is connected can be exposed as shown in FIG. In order to ensure safety, the air purifier 1 is configured such that a high voltage is not supplied when the streamer discharge unit 5 is exposed as shown in FIG. In the connector 71 of the wire harness 70, there are electrical contacts to be protected from water. Although it is unlikely that it will occur in extremely rare cases, it is unlikely that there will be a possibility of electricity leakage if water is splashed in this state and operation starts with the electrical contacts wet. There is no.

  When removing the streamer discharge unit 5 from the state of FIG. 7, the connector 71 of the wire harness 70 is pulled out from the streamer discharge unit 5 as shown in FIG. 8. The streamer discharge unit 5 is provided with a connector pin 6 that is paired with the connector 71 of the wire harness 70. The wire harness 70 is fixed to the inner side of the inner suction grill 16. Therefore, an operator such as a user cannot remove the wire harness 70 together with the streamer discharge unit 5 in a normal operation such as unit replacement or maintenance. FIG. 9 shows a state where the streamer discharge unit 5 is removed. The unit storage portion 18 is provided with an opening 18a. The opening 18 a faces the airflow path from the suction port 21 toward the HEPA filter 25. The streamer discharge unit 5 is provided with two vent holes (not shown) in a portion corresponding to the opening 18a, and the streamer discharge unit 5 allows the activated species generated inside to pass through the vent and the opening 18a. It can be discharged upstream of the HEPA filter 25.

(2-2) First seat cover 61 and second seat cover 62
The first sheet cover 61 and the second sheet cover 62 are in the form of a film, and are made of, for example, a plastic film. As the plastic film, for example, a PET film, a polypropylene film, or a polyethylene film can be used. The plastic film constituting the first seat cover 61 and the second seat cover 62 is not made of holes or the like, is a material that does not allow water to pass from the front to the back, and has water shielding properties. The plastic film is flexible so that an operator can easily bend it by hand. When the first seat cover 61 and the second seat cover 62 are released, the first seat cover 61 and the second seat cover 62 return to the original state due to the elastic force of the plastic film. In order to make it easy for the operator to visually recognize the work target, the plastic film used here for the first sheet cover 61 and the second sheet cover 62 is transparent.

  As shown in FIG. 10, the first seat cover 61 is attached to the upper end portion 16 a of the internal suction grill 16 with an adhesive or an adhesive. The upper end portion 16 a of the internal suction grill 16 is located on the unit storage portion 18. The first sheet cover 61 can be affixed with, for example, a tape with adhesive or adhesive applied on both sides. The pasting area 61a to be pasted in the first sheet cover 61 is the upper part of the area delimited by a broken line. The boundary line of the pasting area 61a indicated by the broken line is the fixed end 61b.

  In the first seat cover 61, the fixed end 61b is disposed above and the free end 61c is disposed below. In other words, the free end 61c disposed below is the lower end. As seen from the outside of the air cleaner 1, the first seat cover 61 can be understood by comparing FIG. 10 with FIGS. 7 and 8, but the connector pins 6 of the streamer discharge unit 5 including the electrical contacts and the wire harness 70. The connector 71 is covered. The distance from the fixed end 61b of the first seat cover 61 to the free end 61c is K1. The horizontal length of the first seat cover 61 is L1.

  As shown in FIG. 11, the second seat cover 62 is attached to the upper end portion 16 a of the internal suction grill 16 with an adhesive or an adhesive. The second sheet cover 62 is stuck on the first sheet cover 61 (see FIG. 14). The second sheet cover 62 can also be affixed with, for example, a tape coated with an adhesive or an adhesive on both sides. In a state where the internal suction grill 16 is fixed to the main body 10, as shown in FIG. 14, the first seat cover 61 and the second seat cover 62 are sandwiched between the internal suction grill 16 and the main body 10. By adopting such a structure, the first sheet cover 61 and the second sheet cover 62 are hardly peeled off.

  The pasting area 62a pasted in the second sheet cover 62 is the upper part of the area delimited by a broken line. The boundary line of the pasting area 62a indicated by the broken line is the fixed end 62b. In a front view (when viewed in a direction in which air is sucked into the internal suction grill 16), the fixed end 62 b of the second seat cover 62 overlaps with the fixed end 61 b of the first seat cover 61. That is, the two-dot chain line in FIG. 10 and the two-dot chain line in FIG. 11 overlap.

  In the second seat cover 62, the fixed end 62b is disposed above and the free end 62c is disposed below. In other words, the free end 62c disposed below is the lower end. When the second seat cover 62 is viewed from the outside of the air purifier 1, it can be understood by comparing FIG. 11 with FIGS. 7 and 8, but the connector pin 6 and the wire harness 70 of the streamer discharge unit 5 including electrical contacts. The connector 71 is covered.

  The distance from the fixed end 62b of the second seat cover 62 to the free end 62c is K2. A distance K2 between the fixed end 62b of the second seat cover 62 and the free end 62c is shorter than a distance K1 between the fixed end 61b of the first seat cover 61 and the free end 61c. Here, since the fixed end 61b of the first sheet cover 61 and the fixed end 62b of the second sheet cover 62 which are above (in the first direction) are at the same position, the free end 61c of the first sheet cover 61 is the second end. Below the free end 62c of the seat cover 62 (in the second direction), it is far from the fixed end 61b of the first seat cover 61. In other words, the lower end (free end 61c) of the first sheet cover 61 is lower than the lower end (free end 62c) of the second sheet cover 62.

  The horizontal length of the second seat cover 62 is L2. In the horizontal direction, the length L2 of the second seat cover 62 is longer than the length L1 of the first seat cover 61. The first sheet cover 61 cannot cover the entire streamer discharge unit 5, but the second sheet cover 62 can also cover the entire streamer discharge unit 5. Since the length L2 of the second sheet cover 62 is long, the drip-proof range can be expanded as compared with the case where only the first sheet cover 61 is provided.

  As shown in FIG. 12, the second sheet cover 62 is printed with a handling instruction relating to members having electrical contacts (here, the streamer discharge unit 5 and the connector-attached wire harness 70). An operator such as a user can handle members having electrical contacts such as the streamer discharge unit 5 and the connector-attached wire harness 70 while confirming the operation method with the description printed on the second sheet cover 62.

(2-3) Cover hooking situation An example of the situation where the connector 71 of the wire harness 70 is hooked on the first seat cover 61 and the second seat cover 62 will be described with reference to FIGS. 13 and 14. In the situation shown in FIGS. 13 and 14, the free end 61 c, which is the lower end of the first seat cover 61, is hooked on the connector 71 of the wire harness 70. The first seat cover 61 is bent by being caught by the connector 71. However, since the second seat cover 62 is lifted by the curved first seat cover 61, the second seat cover 62 is located closer to (above) the fixed ends 61 b and 62 b than the free end 61 c of the first seat cover 61. The free end 62c is prevented from being caught by the connector 71. Then, the second sheet cover 62 becomes a ridge and water drops on the connector 71 are prevented. Here, the case where the first seat cover 61 is hooked on the connector 71 is assumed. However, for example, a similar situation occurs when there is a protrusion on the internal suction grill 16 and the first seat cover 61 is hooked on the internal suction grill 16. Even in such a case, the first seat cover 61 can prevent the second seat cover 62 from being caught by the internal suction grill 16.

(3) Modification (3-1) Modification 1A
