In this case, the 1 st surface 511 extends in parallel with the 1 st portion 421. In a state where the holder 42 is inserted into the device cover 50, at least a part of the 2 nd face 512 is in close contact with the 2 nd part 422 of the holder 42, and the 2 nd face 512 extends in a direction along the 2 nd part 422. In this case, at least a portion of the 2 nd face 512 extends parallel to the 2 nd portion 422.

An annular portion 521 is formed at a central portion in the circumferential direction of the frame portion 52, that is, at a central portion in the left-right direction in this case. The upper end portion of the 1 st part 421 of the retainer 42 is inserted into and retained inside the annular portion 521. The diameter of the circular ring 521 is set to: the ring 521, which is longer than the radial side, i.e., the short side, of the frame 52, is provided: a part of which projects forward from the frame portion 52. A projection 511a is formed radially inward of the annular portion 521.

The annular portion 521 is formed with a cutout portion 521a on the left side in this case on one side in the circumferential direction. The retainer 42 has, at the upper end of the 1 st part 421: a convex portion 421b formed to protrude outward from the 1 st opening 421a. In a state where the retainer 42 is inserted into the device cover 50, the convex portion 421b is fitted into the cutout portion 521a. Accordingly, the retainer 42 is prevented from rotating inside the device cover 50.

When the irradiation unit 41 is housed in the holder 42 and the device cover 50 and fixed to the sump cover 30 by the fastening member 60, the irradiation device 40 is inserted into the recess 38. That is, at least a part of the irradiation unit 41, at least a part of the holder 42, and at least a part of the apparatus cover 50 are located inside the recess 38: is positioned closer to the back side than the front portion 32, that is, closer to the center of the water tub 12. Accordingly, there is no occurrence of: the entire irradiation device 40 in the depth direction may protrude forward from the sump cover 30. Therefore, the increase in the depth of the sump cover 30 corresponding to the depth of the irradiation device 40 as a whole is suppressed.

As shown in fig. 10, the ear portion 37 is provided with: and a hole 371 located above the recess 38. The hole 371 penetrates the ear 37 in the thickness direction, and communicates the space above and below the sump cover 30, thereby communicating the inside and outside of the washing tub in the outer case 11. The hole 371 serves as a passage for guiding the lead wire 414 drawn out from the irradiation unit 41 to the upper side of the sump cover 30.

The hole 371 is closed by the engaging portion 165 of the corrugated tube 16 except for a gap through which the lead wire 414 passes, that is, a rear portion of the hole 371 in this case. In addition, when the irradiation device 40 is fixed to the sump cover 30, the upper end of the holder 42, that is, the upper end of the 1 st part 421 is in close contact with the sump cover 30. That is, the upper end of the 1 st part 421 is in close contact with: the radially inner surface of the outer peripheral surface 381 or the ear 37 of the recess 38 is a lower surface in this case. The inside and outside of the washing tub are kept watertight inside the outer case 11 by the bellows 16 having flexibility and watertightness and the retainer 42. Accordingly, water or steam in the washing tub can be prevented from leaking to the outside of the washing tub through the hole 371.

The length of the cylindrical shape of the housing 413 in the axial direction is set to: the axial length dimension longer than the cylindrical shape of the 2 nd portion 422 is such that the front end 413a of the housing 413 is exposed to the outside of the holder 42 in a state of being inserted into the holder 42. Therefore, the ultraviolet rays or visible rays irradiated from the irradiation unit 41 are suppressed from being obstructed by the holder 42.

On the other hand, the length dimension in the axial direction of the cylindrical shape of the housing 413 is set to: the length dimension of the inclined surface shorter than the 2 nd surface 512 of the apparatus cover 50 is such that the irradiation unit 41 is not exposed radially inward of the apparatus cover 50 in the state of being accommodated in the holder 42 and the apparatus cover 50. Therefore, the situation in which the user looks directly to the irradiation unit 41 is suppressed. In addition, during operation, the laundry is irradiated by the irradiation unit 41, or the user touches the irradiation unit 41 by mistake when loading and unloading the laundry, and the irradiation unit 41 is prevented from falling off.

As described above, the lead 414 extends above the sump cover 30 through the groove 39 provided in the front surface portion 32. The circulation water passage 191 passes through the back side of the front surface portion 32, that is, the inside of the water tank 12. The controller 20 controls the drain valve 172 and the circulation pump 192 to allow water to flow through the circulation water passage 191. When the temperature of the lead 414 becomes high or may become high, the control device 20 can reduce the temperature of the lead 414 by causing water to flow through the circulation water passage 191, thereby suppressing an overheat state.

Further, the circulation water path 191 is located: a region extending radially outward from the recess 38. Further, openings 33 are provided on both sides of the recess 38 in the circumferential direction, and water discharge portions 193 are connected thereto. That is, the irradiation device 40 is installed near the circulation water passage 191. Therefore, when the temperature of the irradiation device 40 becomes high or may become high, the control device 20 can reduce the temperature of the irradiation device 40 by flowing water in the circulation water passage 191, thereby suppressing the overheat state.

According to the present embodiment described above, the washing machine 10 as a laundry treatment apparatus includes: a water tank 12, a rotary tank 13, a water tank cover 30, and an irradiation device 40. The water tank 12 has an opening 121 on the front surface. The rotary tub 13 is provided in the water tub 12 with its front opened. The water tank cover 30 is annularly provided at the opening 121 of the water tank 12. The irradiation device 40 is configured to: the inside of the rotary tub 13 can be irradiated. The water tank cover 30 includes, on the inner peripheral side of the front surface portion 32: a recess 38 recessed toward the rear. The irradiation device 40 is attached to the recess 38 from the front.

Accordingly, the irradiation device 40 can be disposed without projecting the depth of the sump cover 30 forward. Therefore, the influence on the depth of the entire washing machine 10 can be reduced. Further, since the irradiation device 40 is fixed to the water tub cover 30 fixed to the water tub 12, it is less likely to be affected by the vibration of the rotary tub 13. Thus, even if the rotary tank 13 vibrates, the irradiation device 40 is less likely to fall off, and the lead 414 can be prevented from being disconnected. Further, the irradiation device 40 can be provided: at least a part of which is located at the rear of the front face portion 32. Therefore, the irradiation can be performed from a position closer to the rotary tub 13, and the irradiation can be easily performed to the back side of the rotary tub 13. Therefore, the present invention provides a battery pack comprising: the clothes treatment device of the irradiation device 40 can effectively irradiate the inside of the washing tank, is difficult to fall off, and does not prevent the miniaturization of the whole product.

The irradiation device 40 includes: an irradiation unit 41, a holder 42, and a device cover 50. The irradiation unit 41 generates light such as visible light or ultraviolet light. The holder 42 is formed in a hollow cylindrical shape with its upper and lower portions opened by a member having flexibility and water-tightness, and holds the irradiation unit 41 inside. The device cover 50 accommodates the holder 42 inside. In a state where the holder 42 having housed the irradiation unit 41 inside is housed in the apparatus cover 50, by fitting the apparatus cover 50 to the recess 38, the holder 42 is fixed in close contact with the water tank cover 30.

Accordingly, since the retainer 42 having flexibility and water tightness is in water-tight contact with the water tank cover 30, it is possible to suppress: water or steam enters the outer cabinet and the outside of the washing tub from the inside of the washing tub, that is, the inside of the water tub 12 or the rotary tub 13.

Here, a case where the irradiation unit 41 is attached in parallel to the front surface portion 32 of the sump cover 30 and the holder 42 is not bent will be discussed. In this case, when the irradiation unit 41 is pressed from the radially inner side, for example, downward at this time, since the holder 42 has flexibility, there is a possibility that: the irradiation unit 41 moves parallel to the front surface portion 32, or the lead 414 is bent excessively. When this happens frequently, the wire 414 may also break.

In contrast, the holder 42 has: a 1 st portion 421 having a cylindrical axis extending along the front surface portion 32 of the water tank cover 30, and a 2 nd portion 422 provided at a position radially inward of the rotary tub 13 from the 1 st portion 421 and inclined so as to be closer to the radially inward of the rotary tub 13 as the cylindrical axis goes rearward. The irradiation unit 41 is inclined with respect to the rotation axis of the rotation slot 13 along the inclination of the 2 nd part 422.

Accordingly, since the irradiation unit 41 is inclined toward the rear side of the rotary tub 13, the irradiation unit can irradiate not only the front side of the rotary tub 13 close to the irradiation unit 41 but also the inside of the rotary tub 13 without dead space. Further, even if the irradiation unit 41 is pressed from the radial inside, the force can be dispersed by the bending of the holder 42, compared to a case where the irradiation unit 41 is attached in parallel to the front surface portion 32 of the sump cover 30. Therefore, the movement of the irradiation unit 41 is suppressed. Therefore, the irradiation unit 41 can be prevented from falling off the sump cover 30, and the occurrence of disconnection of the lead 414 can be prevented. Therefore, the occurrence of defects in the irradiation device 40 can be reduced.

In addition, the apparatus cover 50 has: a 2 nd face 512 connected to the 2 nd portion 422 of the holder 42 and extending along the 2 nd portion 422, and a 1 st face 511 connected to the 1 st portion 421 of the holder 42 and extending along the 1 st portion 421 and inclined with respect to the 2 nd portion 422 of the holder 42. Therefore, even if the irradiation unit 41 is supposed to be pressed in a direction parallel to the 2 nd part 422 of the holder 42, it interferes with: the 1 st portion 421 of the holder 42 and the 1 st surface 511 of the apparatus cover 50 move along the inclined surface of the irradiation unit 41 from obliquely above. Therefore, the following steps are performed: the irradiation unit 41 is further less likely to fall off.

The washing machine 10 as a laundry treatment apparatus includes: an outer case 11 and a bellows 16. The outer box 11 has an outlet 112 in a front surface 111, and accommodates the water tank 12 and the rotary tank 13 therein. A front end 161 of the bellows 16 is connected to the outlet 112, and a rear end 162 of the bellows 16 is attached to the front surface 32 as a mounting surface of the sump cover 30. The irradiation device 40 is assembled to: at least a part of which is located rearward of the front surface 32 as the mounting surface.

Accordingly, the irradiation device 40 is provided with: the position is rearward of the mounting surface of the corrugated tube 16 and is near the center of the rotary groove 13. Therefore, the irradiation device 40 is configured to: the irradiation light can be further easily irradiated to the inner side of the rotary tub 13. Further, since the lead wire 414 passes between the bellows 16 and the front surface portion 32 as the mounting surface, it is not necessary to widely wind the lead wire 414. Therefore, workability in manufacturing is good, and the length of the lead 414 which is located in the vicinity of the inside of the washing tub and is likely to be exposed to water or steam can be shortened. Therefore, the occurrence of defects in the irradiation device 40 can be reduced.

Here, when irradiation unit 41 irradiates light for a long period of time or when light emitting element 412 is a high-output LED, irradiation unit 41 may generate heat depending on the case.

In contrast, the washing machine 10 as the laundry treatment apparatus includes: a circulation water path 191. The circulation water passage 191 passes through the inside of the sump cover 30, and connects the drain portion 122 provided at the lower portion of the sump 12 and the drain portion 193 that drains water into the sump 12 from above. The irradiation device 40 and the circulation water passage 191 are arranged to overlap each other in the radial direction of the sump cover 30 so that the irradiation device 40 is positioned radially inward of the circulation water passage 191.

Accordingly, since the circulating water passage 191 passes near the irradiation device 40, water flows near the irradiation device 40 during operation, and the irradiation device 40 can be cooled. Accordingly, it is possible to suppress: the irradiation device 40, the lead 414, or the surrounding structure of the irradiation device 40 may reach an excessively high temperature. Therefore, the occurrence of defects in the irradiation device 40 can be reduced.

In the above-described embodiment, the recess 38 is provided above the top of the opening 121, but the present invention is not limited thereto. For example, the recess 38 may be provided with: a position deviated from the top of the opening 121 in the left-right direction. In the present embodiment, the number of the irradiation devices 40 is 1, but the present invention is not limited thereto. A plurality of the irradiation devices 40 may be provided, for example, 2 devices having a bilaterally symmetrical structure.

Although the embodiment of the present invention has been described above, the embodiment is only given as an example and is not intended to limit the scope of the invention. These new embodiments may be implemented in other various ways, and various omissions, substitutions, and changes may be made without departing from the spirit of the invention. These embodiments and modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
