Description

Embodiments of the present invention relate to washing machines.

Conventionally, in order to prevent forgetting to take out the laundry, for example, a washing machine in which the inside of the tub is illuminated by a lighting device has been considered. As a washing machine of this type, for example, Patent Document 1 discloses a configuration in which a lighting device is provided on the inner upper portion of a laundry entrance / exit provided in an outer box.

Japanese Patent No. 3544874

However, in the conventional configuration, the entire lighting device is arranged so as to be inclined toward the inside of the tank. Therefore, the depth dimension of the installation space of the lighting device becomes large, which leads to an increase in the size of the entire washing machine. In addition, as the installation space of the lighting device increases, the distance from the front surface of the washing machine to the inside of the tub becomes long, which makes it difficult to use when taking in and out the laundry.

Further, in the configuration in which the lighting device is provided at the laundry entrance / exit of the outer box, the distance from the lighting device to the inside of the tub becomes long, and the inside of the tub cannot be lit well. In recent years, since the capacity of the tank has been increased, it becomes more difficult to illuminate the inside of the tank well in a configuration in which the distance from the lighting device to the inside of the tank is long.

Therefore, the present embodiment provides a washing machine capable of suppressing the depth dimension of the installation space of the lighting device and satisfactorily illuminating the inside of the tub.

The door 19 is mainly composed of a transparent member such as glass, and the inside of the tub can be visually recognized from the outside of the washing machine 10. Further, the laundry entrance 18 and the opening 16 of the water tank 12 are watertightly connected by a bellows 20. Further, on the upper part of the front surface of the outer box 11, an operation panel (not shown) having various operation buttons such as an operation start button and a display unit is provided. A control device (not shown) is provided on the back side of the operation panel. The control device is mainly composed of a microcomputer and controls the overall operation of the washing machine 10.

Further, the washing machine 10 includes a water supply path (not shown) for supplying water into the water tank 12, a drainage route (not shown) for discharging the water in the water tank 12 to the outside of the machine, and the like. Further, 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 can be considered. For example, a configuration with a heat pump mechanism including a condenser, an evaporator, and the like, a configuration including a heater, and the like can be considered. ..

The washing machine 10 includes a lighting device 30 for illuminating the inside of the drum 13. Note that FIG. 1 schematically shows a configuration related to the lighting device 30 and its peripheral portion. Next, a specific configuration example of the lighting device 30 will be described. That is, as illustrated in FIG. 2, the opening 16 of the water tank 12 is provided with a penetrating portion 50 penetrating the peripheral surface of the opening 16. As illustrated in FIG. 3, the lighting device 30 is attached to the penetrating portion 50. In this case, the penetrating portion 50 is a through hole extending along the tangential direction of the opening 16 at the uppermost portion of the opening 16 of the water tank 12.

The inner peripheral surface of the upper portion of the opening 16 of the water tank 12 is provided with a recess 51 that is recessed outward in the radial direction of the opening 16. The through hole 50 is provided in the recessed portion 51 that is recessed outward in this way. A front side wall portion 52 is provided on the front side of the recessed portion 51. The front side wall portion 52 projects 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. Further, a rear side wall portion 53 is provided on the rear side of the recess portion 51. The penetrating 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 upper front surface of the drum 13, for example, the user's hand may enter the water tank 12 from the recessed portion 51, and eventually the upper front surface 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 composed of, for example, an LED. The light emitting element 33 preferably emits light other than ultraviolet rays, and in this case, a light emitting element that emits white light is adopted. The case portion 32 constitutes the outer shell of the lighting device 30, and the substrate 31 is housed in the tip portion thereof. As illustrated in FIG. 5, the case portion 32 has a long shape extending along the tangential direction of the opening 16 of the water tank 12 corresponding to the opening shape of the penetrating portion 50. Further, the tip portion of the case portion 32 has a hemispherical shape, that is, a shape having an arc-shaped cross section. In this case, the case portion 32 is entirely made of a transparent member.

As illustrated in FIG. 2, the substrate 31 has a front end side surface portion 31a facing downward in the case portion 32, and a proximal end side surface facing downward in the drawing, and a proximal end side surface facing upward in the case portion 32. It has a part 31b. The light emitting element 33 is provided on the front end side surface portion 31a of the double-sided portions 31a and 31b of the substrate 31. Therefore, 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 of being mounted in the tip 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 lighting device 30 is attached by inserting the case portion 32 into the penetrating portion 50. At this time, the insertion direction A of the case portion 32 with respect to the penetrating portion 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.

The lighting device 30 has a configuration in which the substrate 31 is housed in the case portion 32 in a state of being inclined with respect to the insertion direction A of the case portion 32. 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 has a spread of a predetermined half angle Lα with reference to the optical axis L which is the center of light emission. The half angle Lα is an angle representing a range in which the amount of light is halved with respect to the amount of light on the optical axis L. The half angle Lα is different depending on the type, size, performance, and the like of the light emitting element 33 to be used.

Further, the inclination mode of the substrate 31 can be appropriately changed and carried out. Specifically, for example, as shown in FIG. 7, the substrate 31 may be configured to 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 tilted so that the optical axis L of the light emitting element 33 is at an angle toward the latter half of the inner peripheral surface of the drum 13. More preferably, for example, as shown in FIG. 9, the substrate 31 is inclined so that the optical axis L of the light emitting element 33 is at an angle toward the rearmost portion of the inner peripheral surface of the drum 13. That is, the portion of the drum 13 where the laundry tends to remain is the rearmost portion of the bottom of the drum 13. Therefore, by directing the optical axis L of the light emitting element 33 toward the rearmost portion of the drum 13 as much as possible, it is possible to satisfactorily illuminate the 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 housed. The edge portion 45 extends outward from the upper portion of the main body portion 44, and further bends and extends toward the tip end side of the main body portion 44. The edge portion 45 has a front side edge portion 45a and a rear side edge portion 45b. The front edge portion 45a is an edge portion located on the front side of the washing machine 10 when the case portion 32 is attached to the penetrating portion 50. On the other hand, the rear side edge portion 45b is an edge portion located on the rear side of the washing machine 10 when the case portion 32 is attached to the penetrating portion 50. In this case, the rear edge portion 45b is shorter than the front side edge portion 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 regulation rib 55 is an example of the regulation portion, and is a plate-shaped rib orthogonal to the longitudinal direction of the penetration portion 50. When the case portion 32 is attached with the rear side edge portion 45b on the rear side, the lower end portion of the rear side edge portion 45b does not interfere with the upper end portion of the regulation rib 55. Therefore, the case portion 32 can be attached to the penetrating portion 50. However, when the case portion 32 is attached with the front side edge portion 45a on the rear side, the lower end portion of the front side edge portion 45a interferes with the upper end portion of the regulation rib 55, whereby the case portion 32 is penetrated by the penetrating portion 50. Cannot be attached to. That is, the regulating rib 55 has a function of restricting the orientation of the case portion 32 with respect to the penetrating portion 50, in other words, the mounting orientation to the normal mounting orientation. The normal mounting orientation of the case portion 32 is such that the front side edge portion 45a is the front side and the rear side edge portion 45b is the rear side.

When the case portion 32 is attached to the penetrating portion 50 in the normal mounting orientation, the tip portion of the case portion 32 reaches a height lower than the upper end of the opening 16 of the water tank 12, and more specifically, the recess portion 51. It protrudes to a height lower than the upper end of. That is, the tip of the case portion 32 projects from the inner peripheral surface of the opening 16 of the water tank 12, and 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.

The front side wall portion 52 faces the front side of the tip portion of the case portion 32 that protrudes from the inner peripheral surface of the opening 16 of the water tank 12. Therefore, the front side wall portion 52 blocks the light emitted from the light emitting element 33 from the tip end portion of the case portion 32 toward the front side of the washing machine 10. Therefore, it is possible to prevent the light emitted from the tip of the case portion 32 from directly reaching the user located in front of the washing machine 10. That is, the front side wall portion 52 functions as an example of the light-shielding portion.

Further, the lighting device 30 has a configuration in which the substrate 31 is fixed in the case portion 32 by the 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 thereof. The base portion 61 is inclined so that the front side edge portion 45a side is low and the rear side 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 in a state where the substrate 31 is in contact with the base portion 61. ing. Further, in the central portion of the base portion 61, a groove portion 61a extending in the tangential direction of the opening 16 of the water tank 12 is formed. 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 the base portion 61, and the front side edge portion 45a side is long and the rear side edge portion 45b is short. Further, in the central portion of the fixing member 60, a hole portion 60a extending in the tangential direction of the opening 16 of the water tank 12 is provided. The fixing member 60 is formed in a frame shape so as to surround the hole 60a. Further, the fixing member 60 has a shape in which the upper portion is flat 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 is fixed in a state where the substrate 31 is in contact with the base portion 61. At this time, the fixing member 60 may have a configuration in which the substrate 31 is brought into close contact with the base portion 61 as much as possible. Further, the fixing member 60 is fixed with the substrate 31 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. Further, 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. This makes it possible to prevent moisture from the upper surface of the substrate 31, in this case, the base end side surface portion 31b. Further, the substrate 31 is provided with a light emitting element 33 on the front end side surface portion 31a on the base portion 61 side, and the front end side surface portion 31a provided with the light emitting element 33 is coated with a moisture-proof material such as fumi seal or silicon. .. This makes it possible to prevent moisture from the lower surface of the substrate 31, in this case, the front end side surface portion 31a.

In this way, the substrate 31 is subjected to moisture-proof treatment on both side surfaces 31a and 31b. As a result, the occurrence of short circuits and ion migration can be suppressed. Here, the moisture-proof treatment applied to the front end side surface portion 31a mainly corresponds to the 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-proof treatment applied to the base end side surface portion 31b mainly corresponds to the moisture that infiltrates into the case portion 32 after mounting the lighting device 30.

Further, the fixing member 60 has a frame shape having a hole 60a in the central portion. Therefore, it is possible to prevent the potting material in the hole 60a from flowing into the front end side surface 31a, which is the light emitting surface. That is, the fixing member 60 not only exerts the fixing function of the substrate 31, but also functions as a sealing member of 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-shaped substrate 31 is sandwiched between the base portion 61 that is inclined at the same angle and the inclined portion 66 of the fixing member 60. As a result, the substrate 31 can be firmly and in close contact with the base portion 61 and the fixing member 60.

Further, both ends of the fixing member 60 in the longitudinal direction are fixed to the case portion 32 by screws 70. The screw 70 is an example of a fixing means for fixing the fixing member 60 and 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 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 penetrating portion 50. Therefore, the screw 70 is screwed in along the insertion direction A of the case portion 32 with respect to the penetrating portion 50.

If the fixing direction of the fixing member 60 is also tilted with respect to the insertion direction A of the case portion 32 in accordance with the tilt of the substrate 31, the screw 70 is screwed in the direction tilted with respect to the insertion direction A of the case portion 32. become. Therefore, the depth dimension of the case portion 32 is increased. According to the lighting device 30, although the substrate 31 is tilted with respect to the insertion direction A of the case portion 32, the fixing direction of the fixing member 60 for fixing the substrate 31 is the insertion direction of the case portion 32. Not tilted 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 opening 16 of the water tank 12 is provided with a penetrating portion 50 penetrating the peripheral surface of the opening 16. The case portion 32 constituting the outer shell of the lighting device 30 is inserted into the penetrating 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 penetrating portion 50. It is composed. That is, the lighting device 30 is configured such that the case portion 32 constituting the outer shell is not tilted, and the optical axis L of the light emitting element 33 is tilted. Therefore, as compared with the conventional configuration in which the entire lighting device is arranged in an inclined state, the depth dimension of the installation space of the lighting device 30 can be suppressed, and the size of the washing machine 10 as a whole can be suppressed.

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

Further, the lighting device 30 projects from the front surface of the water tank 12 instead of the body 14 of the water tank 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 having a diameter smaller than that of the body 14. It is attached to the peripheral surface of the portion 16. In a configuration in which the lighting 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 well, the entire lighting device is lengthened and the tip portion is extended to the vicinity of the opening of the drum 13. There is a need. Therefore, the size of the lighting device is increased. According to the washing machine 10, since the lighting device 30 is provided in the opening 16 having a diameter smaller than that of the body portion 14, it is not necessary to lengthen the entire lighting device 30 along the insertion direction, and the size can be reduced. it can.

Further, the case portion 32 may be composed of a transparent member at its tip and an opaque member at its remaining portion. Further, the light emitting element 33 may emit light other than white light as long as it emits light other than ultraviolet light. Further, 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 a moisture-proof treatment on both side surfaces 31a and 31b. However, the substrate 31 may have a structure in which at least one of the double-sided portions 31a and 31b is subjected to a moisture-proof treatment. Further, the substrate 31 may be configured not to be subjected to a moisture-proof treatment.

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

The washing machine according to the present embodiment described above includes a water tank, a rotary tank, a penetrating portion, a lighting device, and a fixing member. The aquarium has an opening on the front surface. The rotary tank is provided in the water tank. The penetrating portion penetrates the peripheral surface of the opening of the water tank. The lighting device has a substrate including a light emitting element and a case portion for accommodating the substrate, and illuminates the inside of the rotary tank. The fixing member fixes the substrate in the case portion. The case portion has a base portion and is inserted into the penetrating portion. The fixing member is fixed in a state where the substrate is in contact with the base portion. The optical axis of the light emitting element is inclined with respect to the insertion direction of the case portion.
