Description

  The present invention relates to a dishwasher, and more particularly to a dishwasher door for opening and closing a dish slot provided in the dishwasher.

2. Description of the Related Art Conventionally, there is known a dishwasher that can wash dishes by spraying washing water (for example, warm water mixed with a cleaning agent) toward the dishes stored in the washing room. The tableware is taken in and out of the washing room through a tableware inlet formed on the front surface of the dishwasher, for example.
The tableware slot is covered with, for example, two doors (upper door and lower door) arranged side by side. The upper door is pivotable forward and upward about its upper edge, and the lower door is pivotable downward and forward about its lower edge.

Among this type of dishwasher, for example, there is one in which the front surface of the door (the surface opposite to the tableware slot) is formed of a stainless steel cover (see, for example, Patent Document 1). If the front surface of the door is made of such a stainless steel cover, it has a clean feeling and looks good.
JP 2001-321313 A

Stainless steel covers are usually used without painting because the texture is lost when painted. However, recently, since most dishwashers employ a door with a stainless steel cover as described above, there has been a problem that variations in the appearance of the door are poor.
The present invention has been made under such a background, and an object thereof is to provide a dishwasher door that can diversify appearance variations and has a good appearance, and a dishwasher including the door.

The invention described in claim 1 for achieving the above object is a dishwasher door (4, 4A, 4B, 4C) for opening and closing a dish inlet (3) provided in the dishwasher (1). A main body (41, 41A, 41B, 41C) having an inner surface facing the tableware inlet when closed and an outer surface opposite to the inner surface, and the outer surface of the main body. A transparent cover (42, 42A, 42B, 42C, 42D, 42E, 42F, 42G) for covering the outer surface of the main body, and an inner surface opposite to the inner surface, an outer surface and a predetermined color of the sheet disposed between the inner surface of the transparent cover (45) seen including, the sheet (45), that is reinforced by partially thickness is increased Features .

The alphanumeric characters in parentheses indicate corresponding components in the embodiments described later. The same applies hereinafter.
According to the first aspect, when viewed door for dishwashers from the front (transparent cover side), it can be viewed through the transparent cover, then formed on the side sheet over bets surface. Therefore, if the surface of the sheet over bets in a suitable color or pattern, without using a bother stainless steel cover, it is possible to improve the appearance.

Further, only by changing the color or pattern of the surface of the sheet over preparative, since the appearance of the door for dishwasher can be easily changed, such as when to provide variations of a plurality of types in the appearance of the door for dishwashers Particularly advantageous.
Furthermore, since the surface of the dishwasher door is constituted by a transparent cover, the texture (thickness) can be improved and the appearance is better than when the surface of the dishwasher door is painted.

The fixture (463) may be attached from the transparent cover side, whereby the main body and the transparent cover may be fixed, or the fixture (475) may be attached from the main body side. Therefore, the main body and the transparent cover may be fixed.
The members (ribs, engaging portions, etc.) protruding from the inner surface of the transparent cover (42) are preferably formed on the edge portions (outer edges, opening edges, etc.) of the transparent cover.

  In this case, since members protruding from the transparent cover such as the engaging portion (engaging piece 426) and rib (annular rib 422) are arranged at the edge of the transparent cover, the transparent cover is moved forward (opposite to the main body). The thick part of the member protruding from the back side as seen through when viewed from the above can be made inconspicuous. Therefore, the appearance of the door for the dishwasher can be further improved.

By the way , when the outer surface of the main body and the inner surface of the transparent cover each include a curved surface, the distance between the outer surface of the main body and the inner surface of the transparent cover is uneven due to thermal deformation of the dishwasher door. At the same time, a force may act in the direction of bending with respect to the sheet. In this case, the sheet may bend at a portion where the gap between the main body and the transparent cover is relatively large, and the appearance may deteriorate.

According to the configuration of the present invention, by reinforcing the sheet by increasing the thickness of the portion where the sheet is easily bent, the portion can be made difficult to bend. Therefore, it can prevent that the sheet | seat pinched | interposed between the main body and the transparent cover bends and looks bad.
The sheet (45) may be reinforced by attaching reinforcing members (453, 454) to the surface on the main body (41, 41A, 41B, 41C) side. The reinforcing member may be, for example, a seal-like member or a plate-like member, and is preferably a flexible member.

In this case, the thickness (for example, about 0.3 mm) of the reinforcing member (453, 454) is preferably larger than the thickness (for example, about 0.2 mm) of the sheet (45).
The main body (41, 41A, 41B, 41C) is formed with an exhaust port (7) for discharging steam in the dishwasher (1), and the seat (45) has the exhaust port. An opening (451) may be formed at a position corresponding to, and the thickness around the opening may be increased to be reinforced. The sheet (45) has a reinforcing member (453, 454) attached to the surface on the main body (41, 41A, 41B, 41C) side above the opening from the left end portion to the right end portion of the sheet. It may be reinforced by.

  In this case, the main body and the transparent cover are likely to be deformed around the opening due to the steam discharged from the exhaust port. In particular, when the main body and the transparent cover are not fixed at the peripheral edge of the exhaust port, the gap between the main body and the transparent cover around the opening tends to widen. Therefore, by increasing the thickness around the opening to reinforce the sheet, it is possible to effectively suppress the bending of the sheet.

According to the second and third aspects of the present invention, the outer edge of the inner surface of the transparent cover (42) (for example, the left and right edge portions) protrudes toward the main body (41), and the inner surface of the transparent cover and the main body A water intrusion prevention rib (425) for preventing water from entering between the outer surface and the outer surface is formed .

According to this configuration, when water is about to enter from the gap between the main body and the transparent cover, it is possible to prevent water from entering by the water intrusion prevention rib. Accordingly, it is possible to prevent the appearance of the dishwasher door due to water entering between the transparent cover and the sheet.
If it is configured to include a drain hole (428) for discharging water falling through the water intrusion prevention rib (425), it is intended to prevent water intrusion in an attempt to enter through the gap between the main body and the transparent cover. The water whose intrusion is blocked by the rib is discharged from the drain hole through the water intrusion prevention rib. Therefore, it is possible to more reliably prevent water from entering between the transparent cover and the sheet.

In the invention according to claims 4 and 5 , the transparent cover (42, 42A) has a predetermined thickness, and the outer edge of the outer surface is a convex curved surface (429), and the outer edge of the inner surface. A protrusion (426) for positioning or locking is provided on the part, and this protrusion has a thickness of the transparent cover so that the protrusion enters a blind spot when the transparent cover is viewed from the outer surface side. It is characterized in that the position of the protrusion is related .

For example, when the convex curved surface is viewed from the front of the engaging portion, the light reflected through the convex curved surface causes the light reflected from the inner part of the projection to enter the field of view. The passing light is prevented from entering the field of view.
According to the configuration of the present invention, the distance that the light that enters the field of view through the convex curved surface passes through the transparent cover is almost the same as the distance that the light that enters the field of view through the portion that is not the convex curved surface passes through the transparent cover. Since it does not change, the protruding portion does not look dark through this convex curved surface, and it looks good.

The protrusion (426) may include a claw portion that engages with the main body, or may include a hook portion (426A) that engages with a claw portion (442C) formed on the main body.
The protrusion (426) is engaged with the main body by being inserted from one side into an insertion hole (442B) formed in the main body (41). An umbrella member (444) covering the other side of the insertion hole may be arranged.

In this case, since the other side (inner side of the main body) of the insertion hole is covered with the umbrella member, it is possible to prevent water that has entered the main body from flowing into the insertion hole. Therefore, it is possible to prevent the water from flowing into the insertion hole and the water from entering between the transparent cover and the sheet and deteriorating the appearance of the dishwasher door.
Invention of claim 6, wherein said transparent cover (42, 42A, 42B) in is the positioning or projection for locking (426) is provided on its inner surface, the body surface of the projection It is characterized by being colored in a lighter color than the color of (41) .

  According to this configuration, the distance that the light that enters the field of view through the protrusion passes through the transparent cover is longer than the distance that the light that enters the field of view through the part where the protrusion is not provided passes through the transparent cover. However, since the surface of the projection is colored with a brighter color than the main body, the amount of light entering the field of view through the projection increases, and the projection portion appears relatively bright. As a result, it is possible to prevent the protruding portion from appearing dark, so that the appearance is good.

The surface of the protrusion (426) is preferably colored with a brighter color similar to the color of the main body (41).
As in the inventions of claims 8 and 9 , the main body (41) is formed with an exhaust port (7) for discharging steam in the dishwasher (1), and the transparent cover (42). ) May have an opening (421) formed at a position corresponding to the exhaust port.

In this case, if the transparent cover (42C, 42D) has a shape that does not cover the upper part of the exhaust port (7) on the outer surface of the main body (41) as in the invention described in claim 10 , the exhaust port It is possible to prevent the steam discharged upward from entering the space between the transparent cover and the main body. Therefore, it can prevent that a water drop enters between a transparent cover and a sheet | seat and it looks bad.

As in the invention described in claim 11, the upper portion of the exhaust port (7) on the outer surface of the main body (41) closes the dishwasher door (4) and moves away from the exhaust port. Even if it is configured to be inclined so as to approach the tableware inlet side, it is effective that the steam discharged upward from the exhaust port enters between the transparent cover and the main body and deteriorates the appearance. Can be prevented.

  The main body (41) includes an annular protrusion (431) that protrudes toward the transparent cover (42) and has an inner peripheral surface constituting the exhaust port (7). Even if it is configured to protrude from the outer surface of the transparent cover through the opening (421), the vapor discharged upward from the exhaust port enters between the transparent cover and the main body, and looks Can be effectively prevented.

Further, even when the annular cover (422) protruding toward the main body (41) is formed on the peripheral edge of the opening (421) of the transparent cover (42), the transparent cover (42) is located above the exhaust port. It is possible to effectively prevent the vapor exhausted from entering the gap between the transparent cover and the main body and deteriorating the appearance.
The main body has an outer surface plate (44) constituting the outer surface, and a through hole (441) is formed at a position corresponding to the exhaust port of the outer surface plate, and the annular rib is formed of the through hole. It is preferable that it is the structure which has protruded from the inner surface of the said outer surface board via (it is formed so that it may be bent more than the thickness of the said outer surface plate).

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a perspective view of a dishwasher 1 according to one embodiment of the present invention as viewed from the upper side obliquely upward.
With reference to FIG. 1, the dishwasher 1 is partitioned by a cabinet 2 having a substantially rectangular outer shape. The inside of the cabinet 2 is, for example, a cleaning room 9 for storing tableware to be cleaned. When the operation is started with the tableware stored in the cleaning room 9, the cabinet 2 is arranged in the cleaning room 9. Washing water (for example, warm water mixed with a cleaning agent) is sprayed from the nozzle (not shown) toward the tableware to clean the tableware. This dishwasher 1 also has a drying function, for example, so that the washed dishes can be dried with warm air.

  The front surface of the cabinet 2 serves as a tableware inlet 3 for taking in and out the tableware in the washing room 9. The tableware slot 3 can be covered with, for example, two doors (an upper door 4 and a lower door 5) that are rotatably attached to the cabinet 2. The upper door 4 covers about the upper half of the tableware slot 3, and the lower door 5 covers about the lower half of the tableware slot 3, and each has a convexly curved shape toward the front. The upper door 4 is turnable forward and upward, and the lower door 5 is turnable forward and downward. When the upper door 4 and the lower door 5 are closed, the tableware inlet 3 is covered, and the cleaning chamber 9 is closed watertight.

  At the center of the upper end portion of the lower door 5, for example, a grip portion 6 is attached for the user to grip when the lower door 5 is opened. The user can rotate the lower door 5 downward and forward by grasping the grip 6 and pulling it toward the front. For example, when the lower door 5 is opened, when the lower door 5 is opened, the upper door 4 is opened and the lower door 5 is closed. Accordingly, the upper door 4 is closed.

In the upper center of the upper door 4, for example, an exhaust port 7 communicating with the inside of the cleaning chamber 9 is formed so as to extend in the left-right direction. The steam can be exhausted from the exhaust port 7 when hot cleaning water is jetted in the cleaning chamber 9 or during drying.
An operation panel 8 that is operated by the user when starting the operation of the dishwasher 1 or setting a cleaning course is disposed at the lower front portion of the cabinet 2.

FIG. 2 is a view of the longitudinal section of the upper door 4 as viewed from the right side, and shows only the configuration near the exhaust port 7.
With reference to FIG. 2, the upper door 4 includes, for example, a main body 41 for opening and closing the tableware inlet 3 and a transparent cover 42 covering the front side of the main body 41 (the side opposite to the tableware inlet 3). Yes. The main body 41 includes, for example, an inner surface plate 43 that forms an inner surface facing the tableware slot 3 with the upper door 4 closed, and an outer surface plate 44 that forms the outer surface (front surface) of the main body 41. The inner surface plate 43 is made of, for example, PP (polypropylene), and the outer surface plate 44 is made of, for example, ABS (acrylonitrile butadiene styrene).

  The inner surface plate 43 is provided with, for example, an annular protrusion 431 that is bent so as to protrude forward, and the exhaust port 7 is formed by the inner surface of the annular protrusion 431. Openings 441 and 421 are formed in the outer surface plate 44 and the transparent cover 42 at positions corresponding to the annular protrusions 431 of the inner surface plate 43, respectively. The annular protrusion 431 is inserted into the openings 441 and 421, and the tip of the annular protrusion 431 protrudes forward (frontward from the front surface of the transparent cover 42).

  The transparent cover 42 is made of, for example, transparent AS (acrylonitrile styrene). In this embodiment, for example, the transparent cover 42 is attached to the outer surface plate 44 from the front with the sheet 45 sandwiched between the transparent cover 42 and the main body 41 (outer surface plate 44). The sheet 45 is a flexible member formed with a thickness of about 0.2 mm by, for example, PET (polyethylene terephthalate), and is curved along the surface (front surface) of the outer surface plate 44. The entire surface of 44 is covered. The sheet 45 is transparent, and the surface on the outer surface plate 44 side is color-printed with a predetermined color, for example.

According to such a configuration, when the upper door 4 is viewed from the front (transparent cover 42 side), the surface of the sheet 45 disposed on the rear side can be visually recognized through the transparent cover 42. Therefore, if the surface of the sheet 45 is made an appropriate color or pattern, the appearance can be improved without using a stainless steel cover or the like.
In addition, since the appearance of the upper door 4 can be easily changed simply by changing the color and pattern of the surface of the sheet 45, it is particularly advantageous when there are multiple types of variations in the appearance of the upper door 4. is there.

Furthermore, since the surface of the upper door 4 is constituted by the transparent cover 42, the texture (thickness) can be improved and the appearance is better than when the surface of the upper door 4 is painted.
In this embodiment, the back surface (surface on the main body 41 side) of the transparent cover 42 is formed as a smooth surface without small irregularities. Thereby, the sheet 45 can be uniformly adhered to the entire back surface of the transparent cover 42, so that it is possible to prevent a gap from being generated between the sheet 45 and the transparent cover 42 to deteriorate the appearance.

However, the present invention is not limited to the configuration in which the sheet 45 is sandwiched between the transparent cover 42 and the outer surface plate 44. For example, an effect equivalent to the above effect can be obtained even in a configuration in which the back surface of the transparent cover 42 is painted. It is done.
An annular rib 422 that protrudes toward the main body 41 is formed on the periphery of the opening 421 of the transparent cover 42. The annular rib 422 is longer than the thickness of the outer surface plate 44 and protrudes toward the main body 41, and the tip of the annular rib 422 projects rearward from the rear surface of the outer surface plate 44.

In this embodiment, as described above, the upper door 4 is convexly curved forward, and the surface above the exhaust port 7 of the transparent cover 42 and the outer surface plate 44 has a predetermined angle with respect to the vertical direction V. It is inclined backward by α. According to such a configuration, it is possible to prevent the steam discharged upward from the exhaust port 7 from entering the main body 41 through the gap between the annular protrusion 431 and the opening 421.
Further, since the tip of the annular protrusion 431 protrudes forward from the front surface of the transparent cover 42, the steam discharged upward from the exhaust port 7 passes through the gap between the annular protrusion 431 and the opening 421 and enters the inside of the main body 41. Can be more effectively prevented.

Further, since the annular rib 422 formed on the periphery of the opening 421 of the transparent cover 42 protrudes rearward from the back surface of the outer surface plate 44 (at least the front surface of the outer surface plate 44), it is discharged upward from the exhaust port 7. It is possible to more effectively prevent the steam from entering the main body 41 through the gap between the annular protrusion 431 and the opening 421.
Thus, since the steam discharged upward from the exhaust port 7 can be effectively prevented from entering the main body 41 through the gap between the annular protrusion 431 and the opening 421, water drops enter the main body 41, It is possible to prevent the water droplets from entering between the transparent cover 42 and the sheet 45 and deteriorating the appearance of the upper door 4.

An opening 451 is formed in the sheet 45 at a position corresponding to the annular rib 422 of the transparent cover 42. When the sheet 45 is sandwiched between the transparent cover 42 and the outer surface plate 44, the annular rib 422 is opened. 451 is inserted.
The upper end edge of the transparent cover 42 is curved toward the main body 41 with a relatively large curvature to form a curved portion 420. Further, the upper end edge portion of the outer surface plate 44 is bent with substantially the same curvature as the bending portion 420 at a position facing the bending portion 420 of the transparent cover 42, thereby forming a bending portion 445. The upper edge portion of the sheet 45 extends to the gap between the curved portions 420 and 445 and is sandwiched in a curved state within the gap.

  In this embodiment, a curved portion 452 is formed by bending the upper edge portion of the sheet 45 in advance according to the curvature of each of the curved portions 420 and 445. Thereby, even when the distance between the outer surface plate 44 and the transparent cover 42 becomes non-uniform due to thermal deformation of the upper door 4, the curved portion 452 of the sheet 45 is formed in a previously curved shape. Therefore, it is possible to prevent the curved portion 452 from bending unnaturally and deteriorating in appearance.

  However, the sheet 45 is not limited to a shape in which the upper edge is curved, but may have a shape in which other portions corresponding to the portions where the transparent cover 42 and the outer surface plate 44 are curved are curved. In this case, the entire sheet 45 may be formed along the transparent cover 42 and the outer surface plate 44 so as to correspond to the undulations of the inner surface of the transparent cover 42 and the outer surface of the outer surface plate 44.

FIGS. 3A and 3B are diagrams showing an external configuration of the transparent cover 42, in which FIG. 3A shows a rear view, FIG. 3B shows a left side view, and FIG. 3C shows a bottom view.
Referring to FIG. 3, the transparent cover 42 includes a main plate portion 423 disposed to face the surface of the outer surface plate 44 (sheet 45) of the upper door 4, and a rear side (main body 41 side) over the entire outer edge of the main plate portion 423. ) Projecting pieces 424 (upper projecting piece 424A, lower projecting piece 424B, left projecting piece 424C and right projecting piece 424D).

  A labyrinth rib 425 that protrudes a certain amount in the same direction as the protruding pieces 424C and 424D is formed from the leading edges of the left protruding piece 424C and the right protruding piece 424D (see FIG. 3B). Each labyrinth rib 425 extends along the vertical direction, and an engagement piece 426 that further protrudes rearward is formed at a predetermined position in the vertical direction (for example, three places at equal intervals). On the other hand, engagement pieces 426 are formed on the leading edges of the upper protruding piece 424A and the lower protruding piece 424B so as to protrude rearward from predetermined positions in the left-right direction (for example, six equally spaced locations). Each engagement piece 426 is formed with an engagement hole 426A for engaging with the outer surface plate 44 of the main body 41 to lock the transparent cover 42.

  As described above, the annular rib 422 protruding rearward is formed on the periphery of the opening 421 of the transparent cover 42. From a predetermined position (for example, the upper center portion and the lower left and right end portions) of the tip edge of the annular rib 422, a protruding piece 422A that protrudes further to the rear side is formed. Of these projecting pieces 422A, projecting pieces 422A formed at the left and right end portions on the lower side of the annular rib 422 are formed with claw portions 422B projecting inward of the opening 421. When the transparent cover 42 is attached to the main body 41, the claw portion 422 </ b> B is hooked on the outer peripheral surface of the annular protrusion 431 inserted through the opening 421. Thereby, the transparent cover 42 is firmly fixed to the main body 41 around the exhaust port 7.

  In this embodiment, members that protrude from the transparent cover 42 (main plate portion 423) such as the engagement pieces 426 and the annular ribs 422 are arranged at edge portions such as the outer edge of the transparent cover 42 and the peripheral edge portion of the opening 421. The thick portion of the member protruding from the back side as seen above when the transparent cover 42 is seen from the front can be made inconspicuous. Therefore, the appearance of the upper door 4 can be further improved.

  FIG. 4 is a cross-sectional view when a cross section when the upper door 4 is cut along the left-right direction is viewed from above. 4A is a cross-sectional view when the upper door 4 is cut so as not to pass through the engaging piece 426 of the transparent cover 42, and FIG. 4B shows the engaging piece 426 of the transparent cover 42. It is sectional drawing when the upper door 4 is cut | disconnected so that it may pass. In addition, since the structure of the right-and-left both ends of the upper door 4 is the same, only the structure of the right end part of the upper door 4 is demonstrated in FIG.

The outer surface plate 44 is opposed to the inner surface plate 43 at a predetermined interval, and the main surface portion 442 protrudes rearward (from the inner surface plate 43 side) from the end portion of the main surface portion 442, and forms a side surface of the main body 41. 443. The inner surface plate 43 is attached to the outer surface plate 44 by being fitted into the opening 443 </ b> A configured by the front end edge of the side surface portion 443.
Referring to FIG. 4A, the right end edge of the main surface portion 442 of the outer surface plate 44 is provided with a depth equivalent to the protruding amount of the labyrinth rib 425 at a position corresponding to the labyrinth rib 425 of the transparent cover 42. A concave portion 442A is formed. The concave portion 442A extends in the vertical direction at the right end edge of the main plate portion 442 corresponding to the labyrinth rib 425 extending in the vertical direction. According to this configuration, when water is about to enter from the gap (right side) between the outer surface plate 44 of the main body 41 and the transparent cover 42, the infiltration of water can be prevented by the labyrinth rib 425. Therefore, it is possible to prevent water from entering between the transparent cover 42 and the sheet 45 and deteriorating the appearance of the upper door 4. The water whose intrusion is prevented by the labyrinth rib 425 falls through the gap between the labyrinth rib 425 and the recess 442A (through the labyrinth rib 425).

  Next, referring to FIG. 4B, a portion of the recess 442A corresponding to the engagement piece 426 passes through the outer surface plate 44 (main plate portion 442), and thereby the engagement piece 426 is inserted. For this purpose, an insertion hole 442B is formed. On the left side (the side opposite to the side plate portion 443) of the peripheral edge of the insertion hole 442B, for example, the engagement hole of the engagement piece 426 that protrudes toward the right side (side plate portion 443 side) and is inserted into the insertion hole 442B. A claw portion 442C that engages with 426A is formed.

  An umbrella member 444 is provided on the inner surface of the side surface portion 443 of the outer surface plate 44 so as to cover the insertion hole 442B. The umbrella member 444 includes a top plate portion 444A opposed to the rear of the insertion hole 442B with a predetermined interval, and a side plate portion 444B extending from the upper and lower end portions of the top plate portion 444A to the main surface portion 442 side. The insertion hole 442B is located in the space surrounded by the top plate portion 444A and the side plate portion 444B. According to such a configuration, even when water enters from the gap between the opening 443A of the outer surface plate 44 (side surface portion 443) and the inner surface plate 43, the insertion hole 442B is covered with the umbrella member 444. Can be prevented from flowing into the insertion hole 442B. Therefore, it is possible to prevent the water from flowing into the insertion hole 442B and the water from entering between the transparent cover 42 and the sheet 45 to deteriorate the appearance of the upper door 4.

In particular, when the upper door 4 is opened, the upper door 4 is held in such a posture that the surface of the inner surface plate 43 faces upward, so that the opening 443A of the outer surface plate 44 (side surface portion 443) and the inner surface plate 43 Although water that has entered from the gap easily falls into the insertion hole 442B, the provision of the umbrella member 444 as described above can effectively prevent water from flowing into the insertion hole 442B.
FIG. 5 is a view of the upper door 4 as viewed from below, and shows only the left end portion of the upper door 4. In addition, since the structure of the right-and-left both ends of the upper door 4 is the same, only the structure of the left end part of the upper door 4 is demonstrated in FIG.

  Referring to FIG. 5, for example, a step portion 427 is formed at the left end portion of the lower protruding piece 424 </ b> B of the transparent cover 42. The step portion 427 forms a substantially rectangular drain hole 428 between the outer surface plate 44 of the main body 41 and the transparent cover 42. As described above, the water that has entered the gap between the outer surface plate 44 of the main body 41 and the transparent cover 42 is prevented from entering by the labyrinth rib 425 and falls along the labyrinth rib 425. Thus, the water that has reached the lower end of the upper door 4 is discharged downward through the drain hole 428. Accordingly, it is possible to more reliably prevent water from entering between the transparent cover 42 and the sheet 45.

  FIG. 6 is a view for explaining a modification of the transparent cover 42, and shows a cross-sectional view when the transparent cover is cut so as to pass through the engagement piece 426. 6A shows the shape of the end portion of the transparent cover 42 according to this embodiment, and FIG. 6B shows the shape of the end portion of the transparent cover 42A according to the first modification. FIG. 6C shows the shape of the end portion of the transparent cover 42B according to the second modification.

  The front end portions of the transparent covers 42, 42A, and 42B shown in FIGS. 6A to 6C are convex curved surfaces 429 that smoothly connect the surfaces of the main plate portion 423 and the protruding piece 424 with a predetermined curvature. ing. An engagement piece 426 for attaching the transparent covers 42, 42 </ b> A, 42 </ b> B to the main body 41 is disposed behind the convex curved surface 429. When the transparent covers 42, 42 </ b> A, 42 </ b> B are viewed from the front, a portion inside the rear side of the actually viewed portion of the convex curved surface 429 can be seen due to the refraction of the light L <b> 1 through the convex curved surface 429. When the vicinity of the tip of the convex curved surface 429 is viewed from the near side, the incident angle with respect to the convex curved surface 429 is reduced and the total reflection condition is satisfied. The totally reflected external light L2 enters the field of view.

  In the transparent cover 42 shown in FIG. 6A, the transparent cover 42 is arranged such that the engaging piece 426 enters a blind spot where the engaging piece 426 is not visible when the convex curved surface 429 of the transparent cover 42 is viewed from the front. And the position of the engagement piece 426 are related to each other. That is, when the convex curved surface 429 is viewed from the front of the engagement piece 426, the light L1 reflected by the inner portion (near the convex convex surface 429A) of the engagement piece 429 enters the field of view. The light passing through the engagement piece 429 does not enter the field of view. In this case, the distance that the light L1 that enters the field of view through the convex curved surface 429 passes through the transparent cover 42 is such that the light that enters the field of view through the portion other than the convex curved surface 429 (main plate portion 423) passes through the transparent cover 42. Since it is almost the same as the passing distance, the portion of the engagement piece 426 does not appear dark through the convex curved surface 429, and the appearance is good.

  In the transparent cover 42A shown in FIG. 6B as well, the engaging piece 426 engages when the convex curved surface 429 of the transparent cover 42 is viewed from the front, similarly to the transparent cover 42 shown in FIG. The thickness of the transparent cover 42A and the position of the engaging piece 426 are related so that the piece 426 enters a blind spot where it cannot be seen. That is, when the convex curved surface 429 is viewed from the front of the engagement piece 426, the light L1 reflected by the portion inside the engagement piece 426 enters the field of view and passes through the engagement piece 429. Light does not enter sight. In this case, the distance that the light L1 that enters the field of view through the convex curved surface 429 passes through the transparent cover 42A is such that the light that enters the field of view through the portion (main plate portion 423) that is not the convex curved surface 429 passes through the transparent cover 42A. Since it is almost the same as the passing distance, the portion of the engagement piece 426 does not appear dark through the convex curved surface 429, and the appearance is good.

Like the transparent covers 42 and 42A shown in FIGS. 6 (a) and 6 (b), not only the configuration in which the engagement piece 426 is positioned at the blind spot, but other projections (for example, positioning) protruding from the transparent cover toward the main body 41 side. The projection may be positioned in a blind spot.
The transparent cover 42B shown in FIG. 6C is different from the transparent covers 42 and 42A shown in FIGS. 6A and 6B when the transparent cover 42B is viewed from the front through the convex curved surface 429. An engagement piece 426 is arranged at a position where it enters. That is, when the convex curved surface 429 is viewed from the front of the engagement piece 426, the light L1 passing through the engagement piece 426 enters the field of view. In this case, the distance that the light L1 entering the field of view through the convex curved surface 429 passes through the transparent cover 42B is such that the light that enters the field of view through the portion (main plate portion 423) that is not the convex curved surface 429 passes through the transparent cover 42B. Since it becomes longer than the distance to pass, the part of the engagement piece 426 seen through this convex curved surface 429 looks dark.

  The surfaces of the engagement pieces 426 of the transparent covers 42, 42A, 42B may be colored white using a paint or the like. In this case, the outer surface plate 44 of the main body 41 may be gray. Thus, if the surface of the engagement piece 426 is colored with a lighter color than the color of the main body 41 (more preferably, a brighter color similar to the color of the main body 41), as shown in FIG. The distance that the light entering the field of view through the engaging piece 426 passes through the transparent cover 42B is greater than the distance that the light entering the field of view through the portion where the engaging piece 426 is not provided passes through the transparent cover 42. Even if it is long, the amount of light entering the field of view through the engagement piece 426 increases, and the portion of the engagement piece 426 looks relatively bright. Even with such a configuration, the engagement piece 426 can be prevented from appearing dark, so that the appearance is good.

However, the surface of the engagement piece 426 is not limited to the colored structure, and the surface of another protrusion (for example, a positioning protrusion) protruding from the transparent cover toward the main body 41 may be colored. Good.
FIG. 7 is a rear view of the seat 45.
Referring to FIG. 7, reinforcing seals 453 and 454 for increasing the thickness of the sheet 45 to reinforce the sheet 45 are attached to the back surface (surface on the main body 41 side) of the sheet 45. Yes. The reinforcing seals 453 and 454 are members having flexibility, and the thickness thereof is larger than the thickness of the sheet 45 (for example, about 0.3 mm).

  The reinforcing seal 453 is elongated in the left-right direction, and extends above the opening 451 from the left end to the right end along the upper edge of the opening 451. On the other hand, the reinforcing seals 453 are disposed on both the left and right sides of the opening 451, respectively, a first seal portion 454A located on the side of the opening 451, and a second seal portion 454B extending in the left-right direction from the upper end of the first seal portion 454A. It is formed in the substantially L shape containing. The second seal portion 454B extends on the same straight line as the reinforcement seal 453. The reinforcement seal 453 and the second seal portion 454B of each reinforcement seal 454 allow the upper side of the opening 451 of the seat 45 to be the left end portion of the seat 45. It is in the state reinforced from the right end.

  In this embodiment, the outer plate 44 and the transparent cover 42 are easily deformed around the opening 451 due to the steam discharged from the exhaust port 7. In particular, below the opening 451, the transparent cover 42 is fixed to the main body 41 by engagement of the claw portion 422B and the outer peripheral surface of the annular protrusion 431, whereas above the opening 451, the transparent cover 42 is the main body. 41, the clearance between the transparent cover 42 and the main body 41 above the opening 451 is likely to widen. In this case, the sheet 45 may bend at a portion where the gap between the transparent cover 42 and the main body 41 is relatively large, and the appearance may be deteriorated.

Therefore, by reinforcing the periphery (in particular, the upper part) of the opening 451 with the reinforcing seal 453 as described above, the sheet 45 sandwiched between the main body 41 and the transparent cover 42 is prevented from being bent and looks bad. it can.
However, the reinforcing seals 453 and 454 may be formed integrally. Further, the portion where the reinforcing seal is attached to the sheet 45 is not limited to the upper side and the side of the opening 451, and the reinforcing seal may be attached to the entire periphery of the opening 451, or other than the periphery of the opening 451. A reinforcing seal may be attached to a portion where the sheet 45 is easily bent.

The reinforcing member attached to the back surface of the sheet 45 in order to reinforce the sheet 45 is not limited to a seal-like member, and may be, for example, a plate-like member. Further, the configuration is not limited to the configuration in which the reinforcing member is attached to the back surface of the sheet 45, and for example, the thickness of the sheet 45 itself may be formed to be partially thick.
When the inner surface of the transparent cover 42 and the surface of the sheet 45 on the transparent cover 42 side are smooth, the transparent cover 42 and the sheet 45 are in close contact with each other. At this time, if the gap between the outer plate 44 and the transparent cover 42 is not uniform, when the upper door 4 is viewed from the front side, the gap between the outer plate 44 and the transparent cover 42 is so narrow that the sheet 45 On the other hand, a rainbow-colored pattern (a blur) may appear in a portion where a relatively large pressure is generated. In this case, it looks as if water has entered between the transparent cover 42 and the sheet 45, and the appearance is poor.

  Therefore, in this embodiment, the surface of the sheet 45 on the transparent cover 42 side is subjected to mat processing (sand blast processing, processing using chemicals, etc.) for roughening the surface. According to such a configuration, the surface of the sheet 45 on the transparent cover 42 side can be roughened to reduce the degree of adhesion between the transparent cover 42 and the sheet 45. Thereby, when the upper door 4 is viewed from the front side, it is possible to prevent bleeding from appearing between the transparent cover 42 and the sheet 45 and deteriorating in appearance.

That is, the transparent cover 42 </ b> C covers only the part of the main body 41 below the boundary line X <b> 1. With such a configuration, it is possible to prevent the steam discharged upward from the exhaust port 7 from entering between the transparent cover 42 </ b> C and the main body 41. Accordingly, it is possible to prevent the appearance of water droplets between the transparent cover 42C and the sheet 45 from deteriorating.

  The transparent cover 42 </ b> D shown in FIG. 8B is not located on the inner side (center side) of the boundary line X <b> 2 extending upward along the left and right side edges of the exhaust port 7. That is, the transparent cover 42 </ b> D covers the surface of the main body 41 excluding the upper part of the exhaust port 7. Even with such a configuration, it is possible to prevent the steam discharged upward from the exhaust port 7 from entering between the transparent cover 42 </ b> D and the main body 41. Accordingly, it is possible to prevent the appearance of water droplets between the transparent cover 42D and the sheet 45 from deteriorating.
