Then, the fourth left door body right extending portion 234 of the left door body right U-shaped portion 235 and the right door body left extending portion 322 of the right door body left L-shaped portion 323 are in contact with each other. In contact with or in close proximity, the first left door body right extending portion 231 abuts on the inner surface 301 of the right door body 300 as described above. Then, the left door body 200 and the right door body 300, which are door bodies, form a so-called labyrinth structure central water stop portion (water stop portion) 550 in the vicinity of the center line i (see FIG. 3B).

In the present embodiment, the left door body 200 is closed and then the right door body 300 is closed. However, by changing the configurations of the left door body 200 and the right door body 300 symmetrically, the right door body 300 is closed. The left door body 200 can be closed after closing. Also in this case, similarly to the present embodiment, the left door body 200 and the right door body 300, which are door bodies, form a so-called labyrinth structure central water stop portion 550 in the vicinity of the center line i.

(magnet catch)
As shown in FIG. 2, the opening frame 100 has a magnet catch m in the upper frame portion 110 and the lower frame portion 140 in the vicinity of the center line i. The magnet catch m is provided on the right side of the center line i, attracts the right door body 300, and maintains the closed state. If the left door body 200 and the right door body 300 are closed, the first left door body right extending portion 231 of the left door body 200 that has been closed first hits the inner surface 301 of the right door body 300. The left door body 200 does not open in contact with it.

The magnet catch m on the upper frame portion 110 side is directly attached to the lower surface of the second upper frame extending portion 112. The magnet catch m on the lower frame portion 140 side is attached to the lower frame portion 140 via the bracket b. Here, the bracket b positions the left door body 200 and the right door body 300 so that they can be closed at predetermined positions.

The predetermined positions for closing the left door body 200 and the right door body 300 described in the previous stage are the upper water stop portion 510, the left water stop portion 520, and the right water stop portion by closing the left door body 200 and the right door body 300. This is the position where the 530 and the central water stop portion 550 are formed. In addition, when the lower end portion 410 of the lower water stop portion 540 is inserted into the lower frame gutter-shaped portion 147, the third lower end portion extending portion 413 is in contact with the fifth lower frame extending portion 145. ..

(About the movement of the lower end)
Next, the movement of the lower end portion by the moving mechanism and the connecting mechanism of the present invention will be described.

As shown in FIG. 7B, when the left door body 200 and the right door body 300, which are the door bodies, are opened and closed, the lower end portion 410 is held in the upper position. Further, as shown in FIG. 7C, the lower end portion 410 is moved to the lower position with the door bodies 200 and 300 closed. As a result, the lower end portions 410 of the door bodies 200 and 300 can be engaged with the lower frame portion 140 and kept in a state in which the door bodies 200 and 300 cannot be opened (locked state).

The movement of the lower end portion 410 of the left door body 200 and the right door body 300, which are the door bodies, is performed by the operations shown in FIGS. 12A to 12C. In FIGS. 12A to 12C, the left-right direction of the drawing is used as it is for the explanation. In the following description, the movement of the lower end portion 410 of the right door body 300 will be described, but the movement of the left door body 200 will be the same symmetrically.

First, FIG. 12A shows a state in which the lower end 410 of the right door body 300 is held in the upper position. At this time, the shaft portion 433 receives the load of the moving portion 421 of the moving mechanism 420 and receives a force in the direction of rotating the rotating portion 432 clockwise around the shaft portion 431. However, since the rotating portion 432 having one end connected to the handle portion p via the shaft portion 431 has the other end abutting against the outer peripheral frame 372 of the outer plate, it cannot rotate further clockwise (clockwise). No. As a result, the lower end portion 410 can be held in the upper position without the operator applying a clockwise rotation (clockwise) force to the handle portion p to hold the handle portion p.

At this time, as shown in FIG. 13A, the cross rail bent portion 450 of the cross rail portion 423 is held at a position spaced apart from the upper end bent portion 452 of the bracket portion 427. In this state, the handle, which is the portion to be gripped by the handle portion p, is held in a substantially horizontal direction.

Next, FIG. 12B shows a state in which the lower end 410 of the right door body 300 is in the middle of moving between the upper position and the lower position. At this time, the moving mechanism 420 receives a downward force due to the mass of the lower end portion 410 and the moving mechanism 420, and the force for rotating the handle portion p counterclockwise (counterclockwise) is reduced in order to move the lower end portion 410 to the lower position. can do. At this time, as shown in FIG. 13B, the distance between the horizontal rail portion 450 of the horizontal rail portion 423 and the upper end bent portion 452 of the bracket portion 427 is increased by the horizontal rail portion 423 moving downward. , It is smaller than the interval in FIG. 13 (A).

Next, FIG. 12C shows a state in which the lower end 410 of the right door body 300 is held in the lower position. At this time, the shaft portion 433 receives the load of the moving portion 421 and the lower end portion 410, and receives a force in the direction of rotating counterclockwise around the shaft portion 431.

At this time, as shown in FIG. 13C, the horizontal rail portion 423 of the horizontal rail portion 423 abuts on the upper end bent portion 452 of the bracket portion 427, and the horizontal rail portion 423 moves downward. Is regulated. As a result, the lower end 410 connected to the cross rail 423 is held in the lower position. In this state, the handle, which is the part to be gripped by the handle portion p, is in a state along the substantially vertical direction.

Next, with reference to FIG. 14, the concept of movement of the lower end portion 410 by the moving mechanism 420 and the connecting mechanism 430 will be described.

The straight line L indicated by the alternate long and short dash line indicates the trajectory of the shaft portion 425 of the moving mechanism 420 (see FIG. 9). The black dot LA on the straight line L corresponds to the state (A) in FIG. 12, and indicates the position of the shaft portion 425 in the state where the lower end portion 410 is placed in the upper position PA. Further, the black dot LB on the straight line L corresponds to the state (B) in FIG. 12, and the shaft portion 425 in a state where the lower end portion 410 is in the middle of moving between the upper position PA and the lower position PC. Indicates the position. Further, the black dot LC on the straight line L corresponds to the state (C) of FIG. 12, and indicates the position of the shaft portion 425 in the state where the lower end portion 410 is placed on the lower position PC.

The perfect circle C shown by the alternate long and short dash line is shown for explaining the locus of the shaft portion 433 (see FIG. 9). The black dot CA on the perfect circle C corresponds to the state (A) in FIG. 12, and indicates the position of the shaft portion 433 in a state where the lower end portion 410 is held in the upper position PA. Further, the black dot CB on the perfect circle C corresponds to the state of (B) in FIG. 12, and indicates the position of the shaft portion 433 in the state where the lower end portion 410 is in the middle of moving between the upper position PA and the lower position PC. Shown. Further, the black dot CC on the perfect circle C corresponds to the state (C) in FIG. 12, and indicates the position of the shaft portion 433 in the state where the lower end portion 410 is placed on the lower position PC. Further, the black dot at the center of the perfect circle C indicates the shaft portion 431, and the shaft portion 433 draws a locus of the perfect circle C around the shaft portion 431 via the rotating portion 432.

The straight line shown by the solid line indicates a long connecting portion 434 (see FIG. 9). Therefore, the straight line 434 connects the black point LA and the black point CA, connects the black point LB and the black point CB, and connects the black point LC and the black point CC. That is, it shows that the shaft portion 433 and the shaft portion 425 are connected by the connecting portion 434.

The straight line 434 indicated by the alternate long and short dash line indicates a state in which the shaft portion 431, the shaft portion 433, and the shaft portion 425 are aligned in a straight line. In this state, the black dot CD on the perfect circle C indicates the position of the shaft portion 433, which is the so-called top dead center. At the top dead center, the shaft portion 425 is located at the black point LD on the straight line L, and this point is the highest position in the movement locus of the lower end portion 410.

The shaft portion 425 of the moving mechanism 420 to which the lower end portion 410 is coupled moves from LA to LC via LD and LB when moving from the upper position PA to the lower position PC. That is, the shaft portion 425 of the moving mechanism 420 to which the lower end portion 410 is coupled moves from the upper position PA, once rises, passes through a position higher than the PA, then descends, and moves to the lower position PC. As the shaft portion 425 of the moving mechanism 420 to which the lower end portion 410 is coupled moves, the lower end portion 410 also moves up and down in the same manner. When the shaft portion 425 moves to the upper position PA, the lower end portion 410 moves to the upper position, and when the shaft portion 425 moves to the lower position PC, the lower end portion 410 moves to the lower position.

The shaft portion 433 receives a load from the moving portion 421 via the connecting portion 434 so as to always rotate clockwise (clockwise) or counterclockwise (counterclockwise). Therefore, when the shaft portion 433 is located to the right of the black spot CD, which is the top dead center, it receives a force of clockwise rotation. As a result, the shaft portion 431 is rotated clockwise by rotating the handle, which is the portion to be gripped by the handle portion p, from the state where the lower end portion 410 is held in the lower position, and the shaft portion 433 is rotated. When the shaft portion 433 is moved to the top dead point (black dot CD), the lower end portion 410 exceeds the upper position PA and moves to the highest position. Then, when the shaft portion 433 exceeds the top dead center (black point CD), the weight of the lower end portion 410 causes the rotating portion 432 to move to a position (black point CA) where the rotating portion 432 abuts on the outer peripheral frame 372 of the outer plate, and the lower end portion 410 moves upward. Held in position. Therefore, the lower end portion 410 is rotated to the right by the weight of the lower end portion by rotating the handle, which is the portion to be gripped by the handle portion p, to a position exceeding the top dead center (black point CD) which is a predetermined position, and the upper end portion 410 is rotated to the right by the weight of the lower end portion. Is held at.

On the other hand, when the lower end 410 is moved to the lower PC, the handle p is rotated counterclockwise (counterclockwise) from the state where the lower end 410 is held by the upper PA, and the top dead center (black point) is reached. When the shaft portion 433 is moved to a position beyond the CD), the cross rail portion 423 connected to the shaft portion 433 via the connecting portion 434 is lowered as the shaft portion 433 moves, and the side of the cross rail portion 423 is laterally moved. It moves to the position where the crosspiece bent portion 450 and the upper end bent portion 452 of the bracket portion 427 come into contact with each other (black dot CC), and the lower end portion 410 moves to the lower position PC. At this time, the handle of the handle portion p is in a state along the substantially vertical direction. The handle portion p is a portion to be gripped by the handle portion p until the cross rail bending portion 450 of the moving portion 421 abuts on the upper end bent portion 452 of the bracket portion 427 of the guide portion 422 (see FIG. 13). Some handles are allowed to rotate.

(Flow of wash water scattered around the water return part, the lower end part, and the lower frame part)
Next, when the hinge door 1 is closed and the lower end portion 410 is inserted into the lower frame gutter-shaped portion 147, the flow of the washing water scattered around the water return portion 390, the lower end portion 410, and the lower frame portion 140 is transferred. , FIG. 7 (c) and FIG. 15 will be described in detail.

The washing water (arrow a in FIG. 15) scattered from diagonally above the water return portion 390 comes into contact with the inner surface 301 and flows downward on the inner surface 301 to reach the water return joint portion 399. Of the wash water that has reached the water return coupling portion 399, the strong wash water flows on the slope of the water return extension portion 391 and is returned to the wash tank T at the lower part of the wash space S. Further, of the scattered wash water (arrow a in FIG. 15), the weak wash water flows along the slope of the water return extension portion 391 and is transmitted to the second water return extension portion 392 to return the water. It accumulates in the gutter-shaped part 395. Then, the washing water stored in the water return gutter-shaped portion 395 is flowed back from the water return water port 396 provided on the hinge t side of the water return gutter-shaped portion 395 to the washing tank T at the lower part of the washing space S. ..

Of the wash water (arrow b in FIG. 15) scattered from diagonally above the water return portion 390, the strong wash water comes into contact with the slope of the water return extension portion 391 and flows on the slope of the water return extension portion 391. , It is flushed back to the cleaning tank T at the bottom of the cleaning space S. Further, of the scattered wash water (arrow b in FIG. 15), the weak wash water flows along the slope of the water return extension portion 391 and is transmitted to the second water return extension portion 392 to return the water. It accumulates in the gutter-shaped part 395. Then, the washing water stored in the water return gutter-shaped portion 395 is flowed back from the water return water port 396 provided on the hinge t side of the water return gutter-shaped portion 395 to the washing tank T at the lower part of the washing space S. ..

The wash water (arrow c in FIG. 15) scattered from diagonally above the water return portion 390 comes into contact with the second water return extension portion 392, and from the second water return extension portion 392 to the water return gutter-shaped portion 395. It flows and accumulates. Then, the washing water stored in the water return gutter-shaped portion 395 is flowed back from the water return water port 396 provided on the hinge t side of the water return gutter-shaped portion 395 to the washing tank T at the lower part of the washing space S. ..

Of the washing water scattered from the horizontal direction (arrow d in FIG. 15), it contacts the fifth lower end extending portion 415 and scatters upward, and heads toward the lower surface of the third water return extending portion 393. The washed water comes into contact with the lower surface of the third water return extending portion 393 and is flowed back to the washing tank T at the lower part of the washing space S. Further, of the washing water (arrow d) scattered from the horizontal direction, the washing water (arrow d) comes into contact with the fifth lower end extending portion 415 and is scattered upward, and the fifth lower end extending portion 415 and the third water. The washing water that has entered the gap between the return extending portion 393 and the return extending portion 393 enters the lower end gutter-shaped portion 416. The washing water that has entered the lower end gutter-shaped portion 416 flows through the lower end gutter-shaped portion 416 toward the hinge t side, enters the lower frame gutter-shaped portion 147 from the lower end drainage port 418, and enters the lower frame gutter-shaped portion 147, which will be described later. It is flushed back from the interrupted end of the frame extending portion 145 to the cleaning tank T at the lower part of the cleaning space S.

Of the washing water scattered diagonally from the lower side (arrow e in FIG. 15), the washing water that comes into contact with the third lower end extending portion 413 and flows upward is directed downward by the lower end returning portion 417. Is changed, and it is flushed back to the cleaning tank T at the bottom of the cleaning space S. Further, of the washing water (arrow e in FIG. 15) scattered from diagonally downward, the washing water that comes into contact with the third lower end extending portion 413 and flows downward is the third lower end extending portion 413. At the point where the fifth lower frame extending portion 145 comes into contact with the fifth lower frame extending portion 145, the water flows back to the cleaning tank T at the lower part of the cleaning space S along the cleaning space S side of the fifth lower frame extending portion 145.

Further, the washing water (arrow f in FIG. 15) scattered in the horizontal direction below the arrow d flows upward along the fifth lower frame extending portion 145, and flows in the direction of flowing by the lower end portion return portion 417. It is changed downward and is flushed back to the cleaning tank T at the bottom of the cleaning space S.

As a result, while the washing water is being sprayed in the washing space S with the hinge door 1 closed, the washing water scattered around the water return portion 390, the lower end portion 410 and the lower frame portion 140 is discharged in the cleaning space S. Can be washed back to. Then, the cleaning water sprayed to clean the object to be cleaned G in the cleaning space S is returned to the cleaning tank T provided in the lower part of the cleaning space S. The cleaning water stored in the cleaning tank T is pumped by a cleaning pump, ejected again from the nozzle N, and repeatedly used for cleaning the object to be cleaned G.

(Reflow of wash water by recursive flow path)
After cleaning of the object to be cleaned G is completed and the injection of cleaning water is stopped in the cleaning space S, the inner surface 201 of the inner plate configuration 260 of the left door body 200 and the inner plate configuration of the right door body 300 in the closed state. The cleaning water adhering to the inner surface 301 of the body 360 is flowed back to the cleaning tank T provided in the cleaning space S. Further, when the left door body 200 and the right door body 300 are opened in a state where the handle of the handle portion p is rotated to hold the lower end portion 410 in the upper position, the cleaning is returned to the cleaning tank T. The flow of water will be described with reference to FIGS. 16 and 17 (A) to 17 (C), taking the right door body 300 as an example.

As shown in FIG. 16, a flow path F is formed by cutting out a portion in contact with the lower frame portion 140 at the lower ends of the left frame portion 120 and the right frame portion 130. Further, the fifth lower frame extending portion 145 is interrupted in the middle of the flow path F of the lower frame portion 140 to form a recursive flow path R. The cleaning water that has flowed down from the recursive flow path R into the cleaning space S is returned to the cleaning tank T provided in the cleaning space S.

One end of the lower end 410 on the hinge t side projects to the hinge t side of the right door body 300, and one end of the lower end 410 on the hinge t side is inserted into a notch provided at the lower end of the right frame 130. Then, the right door body 300 can be closed.

As shown in FIG. 17A, with the right door body 300 closed, the water return gutter-shaped portion 395 of the water return portion 390 is a fifth lower frame which is the inner end of the lower frame gutter-shaped portion 147. It is located on the back side beyond the extending portion 145.

With the right door body 300 closed, the washing water adhering to the inner surface 301 of the inner plate constituent 360 of the right door body 300 flows through the inner surface 301, and at the water return gutter-shaped portion 395 and the lower end gutter-shaped portion 416. receive.

The wash water received by the water return gutter-shaped portion 395 can be returned to the wash tank T provided in the wash space S from the water return water port 396.

Further, of the washing water that was not received by the water return portion 390, the washing water received by the lower end gutter-shaped portion 416 has the lower end gutter-shaped portion 416 connected to the hinge t of the right door body 300 by the lower end water flow prevention wall 419. It flows to the side and flows from the lower end water outlet 418 to the lower frame gutter-shaped portion 147.

The left water stop portion 520 stops the wash water scattered in the wash space S so as not to leak to the outside of the housing H from between the left door body left portion 220 of the left door body 200 and the left frame flat surface 126. can do. The left frame plane 126 is formed long in the left-right direction to secure a long contact surface with the inner surface 201 of the left door body 200, thereby further improving the water stopping property.

Further, the left frame L-shaped portion 128 receives the cleaning water scattered substantially in the left-right direction in the cleaning space S, and can flow the cleaning water back to the cleaning tank T provided in the lower part of the cleaning space S. As a result, the washing water is suppressed from entering between the left frame flat surface 126 and the inner surface 201, and the water stopping property of the left water blocking portion 520 is improved.

The left water stop portion 520 forms a gap 21 between the inner plate outer peripheral portion 262 of the left door body 200 and the first left frame extending portion 121. The cleaning water that has soaked into the narrow gap between the inner surface 201 of the left door body 200 and the left frame flat surface 126 flows downward in the gap 21 where the width of the gap widens. The washing water that has flowed downward flows down to the lower frame gutter-shaped portion 147, flows in the direction of the arrow r, and is flowed back from the recursive flow path R to the cleaning tank T provided in the cleaning space S (FIG. 16). And see FIG. 17 (a)).

As shown in FIG. 6B, the inner surface 301 of the right door body 300 and the right frame plane 136 are in contact with each other to form the right water stop portion 530. The right water stop portion 530 prevents the cleaning water scattered in the cleaning space S from leaking to the outside of the housing H from between the right door body right portion 330 of the right door body 300 and the right frame flat surface 136. Can be stopped. Then, the right frame plane 136 is formed long in the left-right direction, and the contact surface of the right door body 300 with the inner surface 301 is secured long, so that the water stopping property is further improved.

The right water stop portion 530 forms a gap 31 similarly to the left water stop portion 520. Then, the washing water that has soaked into the narrow gap between the inner surface 301 of the right door body 300 and the right frame plane 136 flows down due to the gap 31 and flows through the lower frame gutter-shaped portion 147 in the direction of the arrow r, and the recursive flow path R. Is flushed back to the cleaning tank T provided in the cleaning space S.

Further, the right frame L-shaped portion 138 receives the cleaning water scattered substantially in the left-right direction in the cleaning space S, and can flow the cleaning water back to the cleaning tank T provided in the lower part of the cleaning space S. As a result, the washing water is suppressed from entering between the right frame flat surface 136 and the inner surface 301, and the water stopping property of the right water blocking portion 530 is improved.

As shown in FIG. 11C, the first left door body right portion extending portion 231 and the inner surface 301 of the right door body left portion 320 come into contact with each other. Further, the right door body left extending portion 322 of the right door body left portion 320 and the fourth left door body right portion extending portion 234 of the left door body right portion 230 come into contact with each other. As a result, the portion where the left door body 200 and the right door body 300 are close to each other forms the central water stop portion 550 by the so-called labyrinth structure. The central side water stop portion 550 prevents the wash water scattered in the wash space S from leaking to the outside of the housing H from the gap 50 which is the gap between the left door body right portion 230 and the right door body left portion 320. In addition, the water can be stopped.

As described above, the bracket b attached to the lower frame portion 140 positions the left door body 200 and the right door body 300 so that they can be closed at predetermined positions.

The predetermined position for closing the left door body 200 and the right door body 300 is to close the left door body 200 and the right door body 300 so that the upper water stop portion 510, the left water stop portion 520, the right water stop portion 530, and the center side are closed. This is the position where the water stop portion 550 is formed. Further, when the lower end portion 410 of the lower water stop portion 540 is inserted into the lower frame gutter-shaped portion 147, the third lower end portion extending portion 413 is set to a position where it abuts on the fifth lower frame extending portion 145.

As a result, the hinge door 1 of the present embodiment allows the cleaning water sprayed in the cleaning space S to flow to the outside of the housing H from the gap between the opening frame 100 and the left door body 200 and the right door body 300. An upper water stop portion 510, a left water stop portion 520, and a right water stop portion 530 are formed to prevent leakage. Further, a central water stop portion 550 is formed so as not to leak to the outside of the housing H from the gap between the left door body 200 and the right door body 300. While forming these water-stopping portions 510, 520, 530, and 550, the water-stopping property of the lower water-stopping portion 540 can be improved.

Further, by inserting the lower end portion 410 into the lower frame gutter-shaped portion 147, the upper water stop portion 510, the left water stop portion 520, the right water stop portion 530, and the center side water stop portion 550 form the housing H. The hinge door 1 can be locked while preventing the cleaning water sprayed in the cleaning space S from leaking to the outside and improving the water stopping property of the lower water blocking portion 540.

This prevents the door body from being accidentally opened while cleaning the object to be cleaned G in the cleaning space S, and prevents the door body from opening due to the pressure of the cleaning water sprayed in the cleaning space S, thereby preventing the cleaning space. It is possible to prevent the washing water from being scattered from S through the opening 2 to wet the floor surface and to be scattered to the operator and stain the clothes.

The left water stop portion 520 combines the left frame step portion 127 and the left frame L-shaped portion 128 to form the left frame flat surface 126, and the left frame flat surface 126 and the inner surface 201 of the inner plate component 260 are in surface contact with each other. Let the water stop. The reason why the third left frame extending portion 123 and the fourth left frame extending portion 124 are combined is to maintain the strength of the left water blocking portion 520. Therefore, if the strength can be maintained, the second left frame extending portion 122 and the fifth left frame extending portion 125 are formed of one plate, and ribs are formed to maintain the strength. May be good. Alternatively, the second left frame extending portion 122 and the fifth left frame extending portion 125 may be formed of one thick plate.

Similarly to the left water stop portion 520, the right frame water stop portion 530 also forms the right frame plane 136 by combining the right frame step portion 137 and the right frame L-shaped portion 138, and the right frame plane 136 and the inner plate configuration. The water is stopped by making surface contact with the inner surface 301 of the body 360. The reason why the third right frame extending portion 133 and the fourth right frame extending portion 134 are combined is to maintain the strength of the right water blocking portion 530. Therefore, if the strength can be maintained, the second right frame extending portion 132 and the fifth right frame extending portion 135 are composed of one plate, and ribs are formed to maintain the strength. May be good. Alternatively, the second right frame extending portion 132 and the fifth right frame extending portion 135 may be formed of one thick plate.

When the lower end portion 410 is moved to the lower position, the first lower end portion extending portion 411 and the second lower frame extending portion 142 may be brought into contact with each other. By doing so, the third lower end extending portion 413, which is the back side of the door body, and the fifth lower frame extending portion 145 are brought into contact with each other, and the first lower end portion, which is the front side of the door body, is in contact with each other. The extending portion 411 and the second lower frame extending portion 142 can be brought into contact with each other, and the water stopping property of the lower water blocking portion 540 can be further improved.

In consideration of tolerances such as assembly at the time of manufacturing, a predetermined gap, for example, a gap of 1 mm is formed between the inner surface 301 of the inner plate structure 360 and the first upper frame extending portion 111. By arranging the first upper frame extending portion 111 on the back side, it is possible to improve the adhesion of the surfaces that come into contact with the left water stop portion 520 and the right water stop portion 530. In this case, a predetermined gap, for example, a gap of 1 mm is formed in the upper water stop portion 510, but the washing water is less likely to scatter in the upper water stop portion 510, and the first upper frame extending portion 111 is vertical. By setting the length in the direction to a predetermined distance, for example, 60 mm, it is possible to prevent the scattered wash water from leaking from the upper water stop portion 510.

(Double structure of right door body and left door body)
As shown in FIG. 8, in the present embodiment, the main body 380 of the right door body 300 has a double structure of an inner plate constituent 360 and an outer plate constituent 370, and the inner plate constituent 360 and the outer plate are formed. A storage space k is formed between the plate structure 370 and the plate structure 370. Since the connecting mechanism 430 and the moving mechanism 420 are housed in the accommodating space k, the cleaning water sprayed in the cleaning space S and the leftovers scattered from the object to be cleaned G adhere to the connecting mechanism 430 and the moving mechanism 420. Can be prevented.

Further, the cleaning water sprayed in the cleaning space S is cleaning water having a predetermined temperature at which dirt adhering to the object to be cleaned G can be effectively removed, for example, about 60 degrees C, and is sprayed onto the object to be cleaned G. To wash it. When the cleaning water having a predetermined temperature is sprayed in the cleaning space S, the temperature in the cleaning space S rises, which prevents the temperature of the cleaning water having a predetermined temperature from decreasing and reheats the cleaning water to the predetermined temperature. You can save energy.

By forming the accommodating space k inside the main body 380 of the right door body 300, the air in the accommodating space k serves as a heat insulating material, and the temperature in the cleaning space S is transferred to the outside of the housing H. It is possible to prevent the temperature in the cleaning space S from dropping. That is, the accommodation space k has a heat retaining effect of maintaining the temperature in the cleaning space S. Since the temperature in the cleaning space S is unlikely to be transferred to the outer plate constituent 370, it is possible to prevent the outer plate constituent 370 from being heated.

Further, since the accommodating space k is formed inside the main body portion 380 of the right door body 300, the air in the accommodating space k serves as a sound insulating material, and the cleaning water sprayed in the cleaning space S becomes the object to be cleaned G. To suppress the leakage of sound to the outside of the housing H, such as the sound when it comes into contact with the piping and equipment in the cleaning device W, and the sound generated when the objects to be cleaned G that are transported in the cleaning space S come into contact with each other. Can be done. That is, the accommodation space k has a sound insulating effect of suppressing the leakage of the sound generated in the cleaning space S to the outside of the housing H.

A sound absorbing material or a heat insulating material may be stored in the accommodation space k. In that case, the functions of sound insulation and heat insulation can be improved.

Although the double structure of the main body portion 380 has been described with reference to FIG. 8 using the right door body 300, the left door body 200 also has a double structure of the inner plate constituent body 260 and the outer plate constituent body 270. , A storage space k is formed between the inner plate constituent body 260 and the outer plate constituent body 270 of the left door body 200. Therefore, similarly, the left door body 200 can prevent the washing water sprayed in the washing space S and the leftovers scattered from the tableware from adhering to the connecting mechanism 430 and the moving mechanism 420. The heat retaining effect and the sound insulating effect are also provided in the same manner as the accommodation space k of the right door body 300.

(How to clean the cleaning device)
Next, the cleaning method of the cleaning device according to the present invention will be described using the cleaning device W. The cleaning method of the cleaning device may be used for other cleaning devices.

The cleaning method of the cleaning device W of the present invention is to stop the injection of the cleaning water injected to clean the object to be cleaned G in the cleaning space S, open the hinge door 1, and clean the inside of the cleaning device W. Is. Hereinafter, the description will be given step by step.

First, the injection of the washing water from the nozzle N is stopped. Cleaning of the cleaning device W is performed after the injection of the cleaning water is stopped. However, the cleaning device W is used in an environment where the cleaning water is prevented from falling on the floor surface, for example, which is called a dry system. Therefore, even when cleaning the cleaning device W, it is required that the cleaning water does not leak to the outside of the housing.

As shown in FIG. 12A, the handle of the handle portion p is rotated to move the lower end portion 410 to the upper position. When the handle of the handle portion p is rotated to move the lower end portion 410 to the upper position, the rotating portion 432 comes into contact with the outer peripheral frame 372 of the outer plate, and the lower end portion 410 can be held in the upper position. Further, when the rotating portion 432 comes into contact with the outer peripheral frame 372 of the outer plate, the lower end portion 410 receives vibration due to the contact. Due to this vibration, the washing water remaining in the lower end gutter-shaped portion 416 of the lower end portion 410 can be flowed from the lower end flow port 418 to the lower frame gutter-shaped portion 147 of the lower frame portion 140. Further, the washing water adhering to the lower surface side of the second lower end extending portion 412 can be dropped onto the lower frame gutter-shaped portion 147. As a result, when the right door body 300 is opened, the washing water accumulated in the lower end gutter-shaped portion 410 of the right door body 300 and the washing water adhering to the lower surface of the second lower end extending portion 412 fall to the floor. Can be suppressed.

As shown in FIG. 17B, the right door body 300 is then opened. When the right door body 300 was opened, the angle formed by the lower frame portion 140 and the right door body 300 was set to an angle smaller than 90 degrees in the top view, and as described above, it adhered to the inner surface 301 of the right door body 300. most of the washing water received by the bottom end troughs 416 and Mizukae trough 395, flows into the bottom frame gutter member 147, through recursive flow path R of the lower frame trough 147, washing space S After confirming that the door has flowed back to the cleaning tank T at the bottom of the door, the angle between the lower frame portion 140 and the right door body 300 is greater than 90 degrees in top view, as shown in FIG. 17 (C).

Since the cleaning water adhering to the side flows back from the lower frame girder portion 147 to the cleaning tank T provided at the lower part of the cleaning space S, when the right door body 300 is opened, the cleaning water is discharged from the right door body 300 to the floor. It can be suppressed from falling.

Further, when the left door body 200 is opened, the angle formed by the lower frame portion 140 and the left door body 200 is set to an angle smaller than 90 degrees in the top view, and the washing water adhering to the inner surface 201 of the left door body 200 is set. After confirming that most of the water has flowed back to the cleaning tank T at the bottom of the cleaning space S, the angle between the lower frame portion 140 and the left door body 200 is set to an angle larger than 90 degrees in top view. .. By doing so, it is possible to prevent the washing water from falling on the floor surface. Further, the cleaning device W can be easily cleaned by widening the angle formed by the lower frame portion 140 and the left door body 200 at an angle larger than 90 degrees in the top view.
