Description

  Embodiments described herein relate generally to a washing machine.

  Conventionally, for example, in order to prevent forgetting to take out the laundry, a washing machine in which the interior of the tub is illuminated by an illumination device has been considered. As this type of washing machine, for example, Patent Document 1 discloses a configuration in which an illumination device is provided in an upper part on the inner side of a laundry doorway provided in an outer box.

Japanese Patent No. 3544874

  However, in the conventional configuration, the entire lighting device is arranged to be inclined toward the inside of the tank. For this reason, the depth dimension of the installation space of the lighting device is increased, and the overall size of the washing machine is increased. Moreover, since the installation space for the lighting device increases, the distance from the front surface of the washing machine to the inside of the tub becomes long, and usability when putting in and out the laundry is deteriorated.

  Moreover, in the structure which provided the illuminating device in the laundry entrance / exit of the outer box, the distance from an illuminating device to the inside of a tank becomes long, and the inside of a tank cannot be illuminated favorably. In recent years, since the capacity of the tank has been increased, it is more difficult to properly illuminate the inside of the tank in the configuration in which the distance from the lighting device to the inside of the tank is increased.

  Then, this embodiment provides the washing machine which can suppress the depth dimension of the installation space of an illuminating device, and can illuminate the inside of a tank favorably.

  The washing machine according to the present embodiment includes a water tub, a rotating tub, a lighting device, and a light shielding unit. The aquarium has an opening on the front surface. The rotating tank is provided in the water tank. An illumination device is provided at the opening of the water tank and illuminates the inside of the rotating tank. The light blocking unit blocks light emitted from the lighting device.

A washing machine 10 illustrated in FIG. 1 is a so-called horizontal-axis type drum-type washing machine in which the rotation axis direction of the rotation tub is inclined, and a water tub 12, a drum 13, etc. Prepare. The water tank 12 has a bottomed cylindrical shape and is elastically supported by a suspension (not shown). The water tank 12 includes a water tank cover 15 on the front surface of the body portion 14. The water tank cover 15 is provided with a circular opening 16. The opening 16 of the water tank 12 has a smaller diameter than the body part 14 of the water tank 12.

  The drum 13 has a bottomed cylindrical shape and is rotatably disposed in the water tank 12. The drum 13 is an example of a rotating tank. The rotation axis direction of the drum 13 is inclined so that the rear surface side is lower than the front surface side along the front-rear direction of the washing machine 10, that is, the depth direction. The drum 13 is rotated by a drive motor 17 provided on the rear surface of the water tank 12. A circular opening 13 a is provided on the front surface of the drum 13. The opening 13 a of the drum 13 has a smaller diameter than the body of the drum 13. In addition, a plurality of holes (not shown) are provided in the peripheral wall portion of the drum 13. In addition, a plurality of baffles (not shown) are provided on the inner peripheral surface of the drum 13 for picking up laundry.

  On the front surface of the outer box 11, a laundry entrance / exit 18 for taking in and out the laundry is provided. A door 19 is attached to the laundry doorway 18 so as to be openable and closable. The door 19 is mainly composed of a transparent member such as glass, and the inside of the tub is visible from the outside of the washing machine 10. Further, the laundry entrance 18 and the opening 16 of the water tub 12 are watertightly connected by a bellows 20. In addition, an operation panel (not shown) having various operation buttons such as an operation start button, a display unit, and the like is provided on the front upper portion of the outer box 11. A control device (not shown) is provided on the back side of the operation panel. The control device is composed mainly of a microcomputer and controls the overall operation of the washing machine 10.

  The washing machine 10 also includes a water supply path (not shown) for supplying water into the water tank 12 and a drainage path (not shown) for discharging the water in the water tank 12 to the outside of the machine. The washing machine 10 has a drying function for drying the laundry in the drum 13. As a configuration for realizing this drying function, various configurations for supplying warm air into the drum 13 are conceivable. For example, a configuration using a heat pump mechanism including a condenser or an evaporator, a configuration including a heater, or the like can be considered. .

  The washing machine 10 includes an illumination device 30 for illuminating the inside of the drum 13. In addition, in FIG. 1, the structure which concerns on this illuminating device 30 and its peripheral part is shown roughly. Next, a specific configuration example of the illumination device 30 will be described. That is, as illustrated in FIG. 2, the opening 16 of the water tank 12 is provided with a through portion 50 that penetrates the peripheral surface of the opening 16. As illustrated in FIG. 3, the lighting device 30 is attached to the through portion 50. In this case, the through portion 50 is a through hole extending along the tangential direction of the opening portion 16 at the uppermost portion of the opening portion 16 of the water tank 12.

  On the inner peripheral surface of the upper part of the opening 16 of the water tank 12, a recess 51 is provided that is recessed toward the radially outer side of the opening 16. The through hole 50 is provided in the hollow portion 51 that is recessed outward in this way. A front side wall 52 is provided on the front side of the recess 51. The front side wall 52 protrudes in a plate shape toward the center of the opening 16 of the water tank 12 on the front side of the through hole 50. A rear side wall 53 is provided on the rear side of the recess 51. The through portion 50 is provided between the front side wall portion 52 and the rear side wall portion 53. The rear side wall portion 53 is located between the penetrating portion 50 and the front upper portion of the drum 13. For example, the user's hand enters the water tank 12 from the recessed portion 51, and consequently the upper front portion of the drum 13. Prevent contact.

  As illustrated in FIG. 4, the lighting device 30 includes a substrate 31 and a case portion 32. As illustrated in FIG. 2, the substrate 31 includes a light emitting element 33 formed of, for example, an LED. The light emitting element 33 preferably emits light other than ultraviolet rays. In this case, a light emitting element that emits white light is employed. The case part 32 constitutes the outer shell of the lighting device 30 and houses the substrate 31 in the tip part thereof. As illustrated in FIG. 5, the case portion 32 has a long shape extending along the tangential direction of the opening portion 16 of the water tank 12 corresponding to the opening shape of the penetrating portion 50. Moreover, the front-end | tip part of the case part 32 becomes a hemispherical shape, ie, the shape used as a cross-sectional arc shape. In this case, the case part 32 is entirely composed of a transparent member.

  As illustrated in FIG. 2, the substrate 31 includes a distal end side portion 31 a directed toward the distal end side of the case portion 32, the lower side in the drawing, and a proximal end side surface directed toward the upper side in the drawing. Part 31b. The light emitting element 33 is provided on the tip side surface portion 31 a of the both surface portions 31 a and 31 b of the substrate 31. Accordingly, the tip side surface portion 31a constitutes a light emitting surface. Further, in this case, the substrate 31 has a long shape extending along the tangential direction of the opening 16 of the water tank 12 in a state where the substrate 31 is attached in the distal end portion of the case portion 32. The substrate 31 has a configuration in which a plurality of light emitting elements 33 are linearly arranged along the longitudinal direction of the substrate 31. That is, the plurality of light emitting elements 33 are arranged along the tangential direction of the opening 16 of the water tank 12.

  The illumination device 30 is attached by inserting the case portion 32 into the through portion 50. At this time, the insertion direction A of the case part 32 with respect to the penetration part 50 is a direction along the radial direction of the opening 16 of the water tank 12. Further, the insertion direction of the case portion 32 with respect to the penetrating portion 50 is a direction orthogonal to the rotation axis of the drum 13.

  And the illuminating device 30 becomes a structure by which the board | substrate 31 was accommodated in the said case part 32 in the state inclined with respect to the insertion direction A of the case part 32. As shown in FIG. According to this configuration, the optical axis L of the light emitting element 33 is inclined with respect to the insertion direction A of the case portion 32. As illustrated in FIG. 6, the light emitting mode of the light emitting element 33 is a mode having a predetermined half-angle Lα spread with respect to the optical axis L that is the center of light emission. The half angle Lα is an angle representing a range in which the light amount is halved compared to the light amount on the optical axis L. The half angle Lα varies depending on the type, size, performance, and the like of the light emitting element 33 to be used.

  Moreover, the inclination aspect of the board | substrate 31 can be changed and implemented suitably. Specifically, for example, as shown in FIG. 7, the substrate 31 may be inclined so that the optical axis L of the light emitting element 33 is at an angle toward the inner peripheral surface of the drum 13. For example, as shown in FIG. 8, it is preferable that the substrate 31 is inclined so that the optical axis L of the light emitting element 33 is at an angle toward the range of the rear half of the inner peripheral surface of the drum 13. More preferably, for example, as shown in FIG. 9, the substrate 31 is preferably inclined so that the optical axis L of the light emitting element 33 is at an angle toward the rearmost part of the inner peripheral surface of the drum 13. That is, the portion where the laundry tends to remain in the drum 13 is the rearmost portion of the bottom of the drum 13. Therefore, by directing the optical axis L of the light emitting element 33 to the rearmost part of the drum 13 as much as possible, it is possible to satisfactorily illuminate a portion where the laundry tends to remain.

  As illustrated in FIGS. 10 and 11, the case portion 32 has an edge portion 45 around the upper portion of the main body portion 44 in which the substrate 31 is accommodated. The edge portion 45 extends outward from the upper portion of the main body portion 44, and further bends and extends toward the distal end side of the main body portion 44. The edge 45 has a front edge 45a and a rear edge 45b. The front side edge 45 a is an edge located on the front side of the washing machine 10 when the case part 32 is attached to the penetrating part 50. On the other hand, the rear side edge 45 b is an edge located on the rear side of the washing machine 10 when the case part 32 is attached to the penetrating part 50. In this case, the rear edge 45b is shorter than the front edge 45a.

  On the other hand, as illustrated in FIG. 2, a regulation rib 55 is provided on the rear side of the penetrating portion 50. The restriction rib 55 is an example of a restriction portion, and is a plate-like rib that is orthogonal to the longitudinal direction of the penetrating portion 50. When the case portion 32 is attached with the rear edge 45b as the rear side, the lower end of the rear edge 45b does not interfere with the upper end of the regulation rib 55. Therefore, the case part 32 can be attached to the penetration part 50. However, when the case portion 32 is attached with the front side edge 45a as the rear side, the lower end portion of the front side edge portion 45a interferes with the upper end portion of the regulating rib 55, thereby causing the case portion 32 to pass through the through portion 50. Can not be attached to. That is, the regulation rib 55 has a function of regulating the orientation of the case portion 32 with respect to the penetrating portion 50, in other words, the attachment orientation to a normal attachment orientation. The normal mounting direction of the case portion 32 is a direction in which the front side edge 45a is the front side and the rear side edge 45b is the rear side.

  In a state where the case part 32 is attached to the penetrating part 50 in a normal attachment direction, the tip part of the case part 32 is lowered to a height lower than the upper end of the opening part 16 of the water tank 12, more specifically, the recessed part 51. Projects to a height lower than the top of the. That is, the tip of the case portion 32 protrudes from the inner peripheral surface of the opening 16 of the water tank 12, more specifically, from the inner peripheral surface of the recessed portion 51. The tip of the case portion 32 does not protrude at a height lower than the lower end of the front side wall portion 52.

  A front side wall 52 faces the front side of the tip of the case 32 protruding from the inner peripheral surface of the opening 16 of the water tank 12. Accordingly, the front side wall portion 52 blocks light traveling toward the front side of the washing machine 10 from light emitted from the light emitting element 33 from the distal end portion of the case portion 32. Therefore, it is possible to avoid that the light emitted from the distal end portion of the case portion 32 directly reaches the user located in front of the washing machine 10. That is, the front side wall part 52 functions as an example of a light shielding part.

  In addition, the illumination device 30 is configured to fix the substrate 31 in the case portion 32 by a fixing member 60. That is, as illustrated in FIG. 12, the case portion 32 has a base portion 61 on which the substrate 31 is placed inside the tip portion. The base portion 61 is inclined so that the front edge portion 45a side is low and the rear edge portion 45b side is high. As illustrated in FIG. 13, the base portion 61 is inclined so that the optical axis L of the light emitting element 33 is at an angle toward the inner peripheral surface of the drum 13 with the substrate 31 in contact with the base portion 61. ing. Further, a groove 61 a extending in the tangential direction of the opening 16 of the water tank 12 is formed at the center of the base portion 61. The base portion 61 is formed in a frame shape so as to surround the groove portion 61a.

  The fixing member 60 has an inclined portion 66 corresponding to the inclination of the base portion 61 at the lower portion thereof. The inclined portion 66 is inclined at the same angle as that of the base portion 61, and the front edge 45a side is long and the rear edge 45b is short. In addition, a hole 60 a extending in the tangential direction of the opening 16 of the water tank 12 is provided at the center of the fixing member 60. The fixing member 60 is formed in a frame shape so as to surround the hole 60a. In addition, the fixing member 60 has a flat upper portion with respect to the inclined lower portion. That is, the upper surface of the fixing member 60 is along the tangential direction of the opening 16 of the water tank 12.

  The fixing member 60 fixes the substrate 31 in contact with the base portion 61. At this time, the fixing member 60 is preferably configured so that the substrate 31 is in close contact with the base portion 61 as much as possible. Further, the fixing member 60 fixes the substrate 31 in a state of being sandwiched between the fixing member 60 and the base portion 61. At this time, the contact surface between the inclined portion 66 of the fixing member 60 and the substrate 31 and the contact surface between the base portion 61 and the substrate 31 are parallel. The substrate 31 is potted on the fixing member 60 side. That is, a potting material (not shown) such as urethane is applied to the hole 60a of the fixing member 60. Thereby, the upper surface of the substrate 31, in this case, the base end side surface portion 31 b can be moisture-proof. Further, the substrate 31 includes a light emitting element 33 on a tip side surface portion 31a on the base portion 61 side, and a moistureproof material such as Humi seal or silicon is applied to the tip side surface portion 31a including the light emitting element 33. . This makes it possible to prevent moisture on the lower surface of the substrate 31, in this case, the tip side surface portion 31 a.

  As described above, the substrate 31 is subjected to moisture-proof treatment on the both surface portions 31a and 31b. Thereby, generation | occurrence | production of a short circuit or ion migration can be suppressed. Here, the moisture-proofing treatment applied to the tip side surface portion 31 a mainly corresponds to moisture contained in the air sealed in the tip portion of the case portion 32 by the substrate 31 when the lighting device 30 is assembled. On the other hand, the moisture-proofing treatment applied to the base end side surface portion 31 b mainly corresponds to moisture that enters the case portion 32 after the lighting device 30 is mounted.

  The fixing member 60 has a frame shape having a hole 60a at the center. Therefore, it is possible to prevent the potting material in the hole 60a from flowing into the tip side surface portion 31a that is the light emitting surface. That is, the fixing member 60 not only functions to fix the substrate 31 but also functions as a sealing member for the potting material.

  As described above, the fixing member 60 has an inclined portion 66 that is inclined at the same angle as the base portion 61 with respect to the inclined base portion 61. Then, the plate-like substrate 31 is sandwiched between the base portion 61 and the inclined portion 66 of the fixing member 60 that are inclined at the same angle. Thereby, the board | substrate 31 can be fixed in the state firmly and closely_contact | adhered between the base part 61 and the fixing member 60. FIG.

  Further, the fixing member 60 is fixed to the case portion 32 by screws 70 at both ends in the longitudinal direction. The screw 70 is an example of a fixing means for fixing the fixing member 60 and thus the substrate 31 to the case portion 32. Screw holes 71 into which screws 70 are screwed are provided at both ends of the bottom portion of the case portion 32 in the longitudinal direction. The screw hole 71 extends along the insertion direction A of the case portion 32 with respect to the through portion 50. Accordingly, the screw 70 is screwed along the insertion direction A of the case portion 32 with respect to the through portion 50.

  If the fixing direction of the fixing member 60 is also inclined with respect to the insertion direction A of the case portion 32 in accordance with the inclination of the substrate 31, the screw 70 is screwed in a direction inclined with respect to the insertion direction A of the case portion 32. become. For this reason, the depth dimension of the case portion 32 is increased. According to the lighting device 30, the fixing direction of the fixing member 60 for fixing the substrate 31 is the insertion direction of the case portion 32, even though the substrate 31 is inclined with respect to the insertion direction A of the case portion 32. It is not inclined with respect to A. According to this configuration, as described above, since the screw 70 is screwed in along the insertion direction A of the case portion 32, it is not necessary to increase the depth dimension of the case portion 32.

  According to the washing machine 10 according to the present embodiment, the through-hole 50 that penetrates the peripheral surface of the opening 16 is provided in the opening 16 of the water tub 12. In the illumination device 30, the case portion 32 constituting the outer shell is inserted into the penetration portion 50, and the optical axis L of the light emitting element 33 is inclined with respect to the insertion direction of the case portion 32 with respect to the penetration portion 50. It has a configuration. That is, the illumination device 30 is configured to tilt the optical axis L of the light emitting element 33 without tilting the case portion 32 constituting the outer shell. Therefore, compared with the conventional structure arrange | positioned in the state which inclined the whole illuminating device, the depth dimension of the installation space of the illuminating device 30 can be suppressed, and the enlargement as the washing machine 10 whole can be suppressed.

  The lighting device 30 is provided not in the laundry doorway 18 provided in the outer box 11 but in the opening 16 of the water tank 12. Therefore, the distance from the illumination device 30 to the inside of the drum 13 can be shortened as compared with the conventional configuration in which the illumination device is provided at the laundry entrance / exit of the outer box. Therefore, the inside of the drum 13 can be well illuminated, and for example, forgetting to take out the laundry can be prevented.

  The lighting device 30 protrudes from the front surface of the water tub 12 instead of the body portion 14 of the water tub 12, is connected to the laundry entrance 18 on the front surface of the washing machine 10 via the bellows 20, and has an opening smaller in diameter than the body portion 14. It is attached to the peripheral surface of the part 16. In the configuration in which the illuminating device 30 is provided on the peripheral surface of the body portion 14 having a large diameter, in order to illuminate the inside of the drum 13 satisfactorily, the entire illuminating device is lengthened and the tip portion is extended to the vicinity of the opening of the drum 13. There is a need. For this reason, the lighting device is increased in size. According to the washing machine 10, since the illumination device 30 is provided in the opening 16 having a diameter smaller than that of the body portion 14, the entire illumination device 30 does not need to be elongated along the insertion direction, and the size reduction can be achieved. it can. That is, according to the illumination device 30 according to the present embodiment, not only the depth direction can be made compact, but also the insertion direction can be made compact.

  Further, the lighting device 30 is provided at a position higher than the rotation axis of the drum 13, preferably at the top of the opening 16 of the water tank 12 or at a position slightly lower than the top, so that the inside of the drum 13 can be viewed by the user. It can be illuminated from a close position. Therefore, it becomes easier for the user to visually recognize the inside of the drum 13. Further, providing the lighting device 30 at a position as high as possible in the opening 16 of the water tank 12 makes it difficult for the lighting device 30 to be splashed with water, which is preferable from the viewpoint of waterproofing.

In this case, the illumination device 30 emits white light. Thereby, the laundry in the drum 13 can be made to shine white, and a visually clean feeling can be improved.
Further, in the illumination device 30, the tip of the case portion 32 in which the light emitting element 33 that is a light emitting source is accommodated has a hemispherical shape. Therefore, the light emitted from the light emitting element 33 can be diffused, and the interior of the drum 13 can be illuminated over a wider range. In addition, by further embossing the surface of the tip part of the case part 32, light can be diffused more and a wider range can be favorably illuminated.

  In addition, by projecting the tip of the case portion 32 in which the light emitting element 33 that is a light emitting source is housed to a height lower than the upper end of the opening 16 of the water tank 12, light is blocked by the opening 13 a of the drum 13. Can be avoided, and the interior of the drum 13 can be better illuminated.

(Second Embodiment)
In the configuration example shown in FIG. 14, the washing machine 10 includes a circulation water channel 80 that circulates the water in the water tank 12. The circulation water channel 80 is connected to a drainage channel (not shown) and includes a circulation pump (not shown) for pumping water. The circulation water channel 80 repeats circulation by taking in the water in the water tank 12 through the drainage path and returning it into the water tank 12 by driving the circulation pump. The washing machine 10 further includes a discharge port 81 that discharges water circulated through the circulation water channel 80 into the water tank 12. The discharge port 81 ejects circulating water in a shower shape from the upper part of the opening 16 of the water tank 12 into the drum 13. The lighting device 30 is provided in front of the discharge port 81.

  According to the present embodiment, the water ejected from the discharge port 81 in a shower shape can be illuminated by the light emitted from the lighting device 30. That is, the water sprayed in a shower-like manner can be brightly illuminated in the tank, and the cleaning performance can be visually enhanced.

(Third embodiment)
In the configuration example shown in FIG. 15, the lighting device 30 includes a reflecting portion 90 that reflects light outside the tip portion of the case portion 32. The reflecting portion 90 is a film-like member made of a material that reflects light, such as a metal material. In this case, the reflecting portion 90 is attached to the front side of the outer surface of the tip portion of the case portion 32, that is, the side opposite to the drum 13. The lighting device 30 may be configured to include the reflecting portion 90 inside the tip portion of the case portion 32. Further, the lighting device 30 may be configured to include the reflecting portion 90 on both the inside and the outside of the tip portion of the case portion 32.

  According to the present embodiment, as illustrated in FIG. 16, the light emitted from the light emitting element 33 toward the opposite side of the drum 13 can be reflected by the reflecting portion 90 and guided into the drum 13. . Therefore, it is possible to better illuminate the inside of the drum 13.

(Fourth embodiment)
In the configuration example shown in FIG. 17, the washing machine 10 includes a reflecting portion 90 that reflects light at a portion of the front side wall portion 52 that faces the tip portion of the case portion 32. According to this configuration, as illustrated in FIG. 18, light directed from the light emitting element 33 toward the side opposite to the drum 13 can be reflected by the reflecting portion 90 and guided into the drum 13. Therefore, it is possible to better illuminate the inside of the drum 13.

  In this case, as illustrated in FIG. 19, the illumination device 30 may be configured such that the substrate 31 is inclined at an angle at which the optical axis L of the light emitting element 33 faces the reflecting portion 90 of the front side wall portion 52. According to this configuration, the light emitted from the light emitting element 33 can be guided into the drum 13 via the reflecting portion 90. At this time, the incident angle of the light that is reflected by the reflecting portion 90 and indirectly enters the drum 13 is gentler than the incident angle of the light that directly enters the drum 13 from the illumination device 30. Therefore, the light emitted from the light emitting element 33 can easily enter the drum 13, and the inside of the drum 13, particularly the back side, can be irradiated more brightly.

(Other embodiments)
The present embodiment is not limited to the above-described embodiment, and can be expanded or modified as follows, for example.

  For example, if the penetration part 50 is a position higher than the rotating shaft of the drum 13, it can implement by changing that position suitably. For example, the penetrating part 50 may be provided at a position slightly lower than the uppermost part of the opening 16 of the water tank 12.

  The tip of the case 32 extends to the height of the upper end of the opening 16 of the water tank 12, that is, the height of the tip of the case 32 and the height of the upper end of the opening 16 of the water tank 12. May be the same. Also with this configuration, the inside of the tank can be illuminated with light emitted from the tip of the case portion 32.

  Further, the distal end portion of the illumination device 30, that is, the distal end portion of the case portion 32 protrudes downward toward the rotation axis of the drum 13. Here, the tip end portion of the case portion 32 may extend to a height lower than the upper end of the opening 13 a of the drum 13. The tip of the case 32 extends to the height of the upper end of the opening 13a of the drum 13, that is, the height of the tip of the case 32 and the height of the upper end of the opening 13a of the drum 13. May be the same.

  Moreover, the case part 32 may comprise the front-end | tip part with a transparent member, and may comprise the remaining part with an opaque member. The light emitting element 33 may emit light other than white light as long as it emits light other than ultraviolet light. The substrate 31 may be configured to include one light emitting element 33.

  Since the inside of the tub of the washing machine 10 becomes highly humid, it is preferable that the substrate 31 is subjected to moisture-proof treatment on both side portions 31a and 31b. However, the board | substrate 31 is good also as a structure which performs a moisture-proof process to at least any one surface among the double-sided parts 31a and 31b. Moreover, the board | substrate 31 is good also as a structure which does not perform a moisture-proof process.

  The fixing means is not limited to the screw 70 and may be constituted by a pin, for example. That is, various means can be employed as the fixing means as long as the fixing member 60 can be fixed to the case portion 32.

  The washing machine which concerns on this embodiment demonstrated above is provided with a water tank, a rotation tank, a penetration part, an illuminating device, and a light-shielding part. The aquarium has an opening on the front surface. The rotating tank is provided in the water tank. The penetration part penetrates the peripheral surface of the opening of the water tank. An illumination device is provided at the opening of the water tank and illuminates the inside of the rotating tank. The light blocking unit blocks light emitted from the lighting device.

  According to this structure, although the board | substrate is inclined, it is not inclined as the whole illuminating device, Therefore The depth dimension of the installation space of an illuminating device can be suppressed. Moreover, the distance from an illuminating device to the inside of a tank can be shortened, and the inside of a tank can be illuminated favorably.
