The present invention relates to a washing machine that washes items such as tableware.

A washing machine (dishwashing machine) is known that sprays washing water stored in a washing tank onto dishes contained in a washing chamber to wash them, and sprays rinsing water stored in a rinsing tank onto dishes to rinse them. For example, Patent Document 1 discloses a washing machine in which, in a machine room extending in a first direction and a second direction perpendicular to the first direction, the rinsing tank is arranged so that the first direction is the longitudinal direction, and the washing tank is arranged so that the second direction is the longitudinal direction. In the washing machine of Patent Document 1, a rinsing pump is arranged on one side of the washing tank in the first direction, and the rinsing pump and the rinsing tank are configured to be freely attached and detached to the machine room. In a washing machine configured in this way, the rinsing pump and the rinsing tank were easily attached and detached from one side of the machine room in the first direction. This resulted in excellent maintainability of the rinsing pump and the rinsing tank from one side of the machine room in the first direction.

Japanese Patent Application Publication No. 11-206674

In such a washer, it may be desirable to position the washing tank in the same direction (first direction) as the extension direction of the rinsing tank. However, in this case, since the washing tank extends to one side in the first direction, it becomes difficult to position the rinsing pump on one side of the washing tank in the first direction, as in the past. This creates a problem in that it is not possible to ensure the maintainability of the rinsing pump and rinsing tank.

The object of the present invention is to provide a washer in which the longitudinal direction of the washing tank and rinsing tank are arranged in a first direction of the machine room, and the washing tank and rinsing tank are arranged in a second direction, and the maintenance of the rinsing tank and rinsing pump can be ensured from one side in the first direction of the machine room.

The washing machine of the present invention comprises a washing tank that stores washing water used to wash the object to be washed, a washing pump that delivers washing water to a washing chamber that contains the object to be washed, a rinsing tank that stores rinsing water used to rinse the object to be washed, a rinsing pump that delivers rinsing water to the washing chamber, and a machine chamber that is disposed below the washing chamber and forms a space that extends in a first direction and a second direction perpendicular to the first direction when viewed vertically, the washing tank and the rinsing tank are disposed in the machine chamber so that the first direction is the longitudinal direction and are aligned in the second direction, and the rinsing pump is detachably disposed in the machine chamber so that it is on one side in the first direction of the rinsing tank that is detachable from the machine chamber and in line with the rinsing tank in the first direction.

In a washer with this configuration, the components to be maintained, i.e., the rinsing tank and the rinsing pump, are arranged in a row in the first direction, so if the rinsing pump is removed from one side in the first direction, the rinsing tank can also be removed from one side in the first direction. In addition, since the rinsing pump, which is generally smaller in size than the rinsing tank, is arranged on one side of the rinsing tank in the first direction, it is easy to access the rinsing tank from one side in the first direction after removing the rinsing pump. As a result, in a configuration in which the longitudinal direction of the washing tank and the rinsing tank are arranged in the first direction of the machine room and the washing tank and the rinsing tank are arranged in the second direction, it is possible to ensure maintainability of the rinsing tank and the rinsing pump from one side in the first direction of the machine room.

The second flow path 68B is usually fixed, for example, to the outer surface of the front portion 6e of the rinsing tank 6 in a state in which its tip is higher than the full water level (the position of the overflow portion 63) in the rinsing tank 6. A plug is provided at the tip of the second flow path 68B. When it is desired to discharge the water stored in the rinsing tank 6, the plug at the tip is removed and the tip with the plug removed is moved to a position lower than the bottom of the rinsing tank 6.

5, 8 and 9, the first flow path 68A extends from the connection port 6b of the rinsing tank 6 to the front end in the front-rear direction. The tip of the first flow path 68A has a first connection part 68d that opens to the front end in the front-rear direction. A second connection part (connection part) 71a formed on the suction port 71 of the rinsing pump 7 is detachably connected to the first connection part 68d. For example, the first connection part 68d and the second connection part 71a are connected by inserting (fitting) the tip of the first connection part 68d into the opening of the second connection part 71a. An O-ring is arranged on the inner peripheral surface of the second connection part 71a and is in liquid-tight contact with the outer peripheral surface of the first connection part 68d.

The rinsing pump 7 is removably fixed to the inner surface of the bottom 11F of the machine room 1A by the rinsing pump fixing part 75. The rinsing pump 7 is attached to the machine room 1A with the suction port 71 opening toward the back in the front-to-rear direction and the discharge port 72 opening toward the left in the left-to-right direction. The rinsing pump fixing part 75 has a plate-shaped part that protrudes forward in the front-to-rear direction from the lower end of the rinsing pump 7, and the plate-shaped part is attached to the inner surface of the bottom 11F of the machine room 1A by screws or the like (not shown). The rinsing pump 7 is fixed to the rear of the lower front panel 11D by the rinsing pump fixing part 75.

The rinsing tank 6 is formed with an overflow section 63 through which water exceeding a predetermined water storage volume is discharged. A drain hose (not shown) is connected to the overflow section 63. The water flowing out from the overflow section 63 is configured to be discharged through the drain hose, for example, into the storage section 22 of the cleaning tank 20 in the machine room 1A or to be discharged outside the machine. The overflow section 63 is formed on the front side section 6e (a surface constituting one side in the first direction) that constitutes the front side in the front-rear direction of the rinsing tank 6. The rinsing tank 6 is provided with a valve 60B that controls the inflow of water from the water supply pipe 60 in a detachable manner. The valve 60B is detachably attached to the outer surface of the left side section 6c of the rinsing tank 6 by a valve support section (rinsing valve support section) 69A and a valve attachment section (rinsing valve attachment section) 69B, and is connected to a valve connection section 6d provided on the left side section 6c of the rinsing tank 6.

The valve support part 69A is made of a material such as stainless steel, and is attached to the valve 60B. The valve support part 69A has a fixing surface 69Aa formed by bending, which is a surface perpendicular to the front-rear direction. The valve attachment part 69B is made of a material such as stainless steel, and is detachably provided on the outer surface of the left side part 6c of the rinsing tank 6. The valve attachment part 69B has a fixing surface 69Ba formed by bending, which is a surface perpendicular to the front-rear direction. The valve attachment part 69B supports the valve support part 69A in a state in which the valve 60B is supported. The fixing surface 69Aa of the valve support part 69A in a state in which the valve 60B is supported is detachably attached to the fixing surface 69Ba of the valve attachment part 69B by a screw 69 that is screwed from the front side in the front-rear direction.

Here, we will explain the procedure for removing the rinsing pump 7 and rinsing tank 6 from the machine room 1A, for example during maintenance. First, the lower front panel 11D is removed from the frame to open the inside of the machine room 1A to the outside. Next, the screw 69 that secures the valve support part 69A and the valve mounting part 69B is removed, and the valve 60B is removed from the valve connection part 6d. The head of the screw 69 faces forward in the front-to-rear direction, so work can be done from the front of the machine room 1A.

Next, the rinsing pump fixing part 75 is removed from the bottom 11F of the machine chamber 1A. Specifically, the screws (not shown) that attach the rinsing pump fixing part 75 to the bottom 11F of the machine chamber 1A are removed. This allows the rinsing pump 7 and the rinsing pump fixing part 75 to be removed integrally from the machine chamber 1A. Next, the rinsing pump 7 is removed from the rinsing tank 6. Specifically, by pulling the rinsing pump 7 forward, the second connection part 71a of the rinsing pump 7 that is fitted into the first connection part 68d of the first flow path 68A is pulled out from the first connection part 68d. This releases the connection between the first connection part 68d of the first flow path 68A and the second connection part 71a of the rinsing pump 7.

Next, the drain hose connected to the overflow portion 63 of the rinsing tank 6 is removed, and the rinsing tank 6 is then pulled forward. This causes the outer surface of the bottom 6a of the rinsing tank 6 to slide over the upper surface of the first connecting portion 66b of the first rinsing tank fixing portion 66. Also, the second connecting portion 67b of the second rinsing tank fixing portion 67 attached to the rinsing tank 6 slides over the inner surface of the bottom 11F of the machine chamber 1A. Then, the clamping portion 65c of the clamping portion 65 attached to the outer surface of the bottom 6a of the rinsing tank 6 is pulled out of the insertion portion 66e of the first rinsing tank fixing portion 66. This releases the fixation (positioning) of the rinsing tank 6 to the machine chamber 1A. The rinsing tank 6 can then be removed from the machine chamber 1A.

Next, the procedure for attaching the rinsing pump 7 and the rinsing tank 6 to the machine room 1A will be described. The rinsing tank 6 with the second rinsing tank fixing part 67 attached to the outer surface of the bottom 6a is placed on the inner surface of the bottom 11F of the machine room 1A and pushed toward the back side in the front-to-rear direction. As a result, the outer surface of the bottom 6a of the rinsing tank 6 slides on the upper surface of the first connecting part 66b of the first rinsing tank fixing part 66. Also, the second connecting part 67b of the second rinsing tank fixing part 67 attached to the rinsing tank 6 slides on the inner surface of the bottom 11F of the machine room 1A. At this time, the rinsing tank 6 is pushed out so that the clamping part 65c of the clamping part 65 attached to the outer surface of the bottom 6a of the rinsing tank 6 is inserted into the insertion part 66e of the first rinsing tank fixing part 66. As a result, the clamping portion 65c of the clamping portion 65 is inserted into the insertion portion 66e of the first rinsing tank fixing portion 66, and the first connecting portion 66b of the first rinsing tank fixing portion 66 is clamped between the outer surface of the bottom portion 6a of the rinsing tank 6 and the clamping portion 65c of the clamping portion 65. In other words, the rinsing tank 6 is fixed (positioned) relative to the machine chamber 1A.

Next, a drain hose is attached to the overflow portion 63 of the rinsing tank 6, and the rinsing pump 7 with the rinsing pump fixing portion 75 attached is attached to the bottom portion 11F of the machine room 1A. Specifically, the first connection portion 68d of the first flow path 68A and the second connection portion 71a of the rinsing pump 7 are aligned in a straight line in the front-to-rear direction, and then the rinsing pump 7 is pushed backward. As a result, the second connection portion 71a of the rinsing pump 7 is inserted (fitted) into the first connection portion 68d of the first flow path 68A, and the second connection portion 71a and the first connection portion 68d are connected. Next, the rinsing pump fixing portion 75 is attached to the bottom portion 11F of the machine room 1A with a screw (not shown). As a result, the rinsing pump 7 is fixed to the machine room 1A, and the rinsing tank 6 is restricted from moving forward in the front-to-rear direction. Next, the valve support part 69A with the valve 60B fixed thereto is fixed to the valve mounting part 69B, and the valve 60B is connected to the valve connection part 6d. Then, the lower front panel 11D is attached to the frame.

As shown in Figures 12 and 13, the door section 15 has a handle 15A and a door body 15B. The door body 15B has a first door panel 151A arranged on the outside OS (see Figure 14), which is the side opposite the cleaning chamber 1B when attached to the main body section 1, and a second door panel 151B arranged on the inside IS (see Figure 14), which is the cleaning chamber 1B side in the front-to-rear direction. The first door panel 151A and the second door panel 151B are made of a material such as stainless steel.

12 and 14, the first door panel 151A has a standing portion 151Ad standing from the main surface 151Ac on the left and right outer edges. A flange portion 151Ae is formed at the tip of the standing portion 151Ad. The second door panel 151B has a main surface 151Ba and a flange portion 151Bb formed on the outer edge of the main surface 151Ba. The second door panel 151B is arranged such that the flange portion 151Bb of the second door panel 151B overlaps the flange portion 151Ae of the first door panel 151A. The overlapping portion with the flange portion 151Bb of the second door panel 151B is welded. The welded portion W between the flange portion 151Bb and the flange portion 151Ae may be provided intermittently or continuously. In this embodiment, the door section 15, in which the first door panel 151A and the second door panel 151B are formed by welding, will not twist even if a torsional force is applied, and the rigidity of the door section 15 can be increased.

The handle 15A extends in the left-right direction, and on the outer side, a gripping portion 15Ac that can be gripped by an operator is formed. The lower end 15Aa of the handle 15A is attached to the upper end of the door body 15B (first door panel 151A). The lower end of the handle 15A is formed with a claw portion 15Ab that can be inserted into a long hole 151Ab formed in the upper end 151Aa of the first door panel 151A. With the claw portion 15Ab inserted into the long hole 151Ab, the handle 15A is slid in the long hole direction relative to the door body 15B, so that the claw portion 15Ab and the lower end 15Aa clamp the upper end 151Aa, and the handle 15A and the door body 15B are fixed. Furthermore, the handle 15A is fixed at both the left and right ends to the second door panel 151B of the door body 15B by left and right screws 15Ad, 15Ad.

As shown in Figures 15 to 18, the door section 15 is attached via a door hinge 152 attached to the main body section 1. The door hinge 152 has a plate-shaped section 153, a rotating section 154A, and a screw 154B. The plate-shaped section 153 constitutes a portion that is attached to the main body section 1 as described in detail later. The rotating section 154A is provided on the plate-shaped section 153 and is a hinge pin that rotatably supports the stopper 155. The screw 154B functions as a retainer that prevents the stopper 155, which is rotatably provided on the rotating section 154A, from coming out of the rotating section 154A. When the door hinge 152 is attached to the main body section 1, the stopper 155 rotates around an axis A that extends in the left-right direction and horizontally relative to the rotating section 154A. With this configuration, the door section 15 is rotatable around the axis A. In this embodiment, the door portion 15 and the door hinge 152 are integrally formed.

The plate-shaped portion 153 is formed in a plate shape. The plate-shaped portion 153 is formed with a convex shape to improve its strength (rigidity). The stopper 155 is formed in a plate shape like the door hinge 152, and is fixed to the door body 15B. In the dishwasher 100 of this embodiment, the plate-shaped stopper 155 is configured to be rotatable relative to the plate-shaped portion 153 via the rotating portion 154A, so that the rotating structure in the door portion 15 can be configured compactly and thinly. This makes it possible to provide the rotating structure in the door portion 15 in the narrow space between the rinsing pump 7 and the side panel 11A, as shown in FIG. 18.

The plate-shaped portion 153 is attached to the main body 1. The plate-shaped portion 153 is attached to the fixed portion 18 by inserting a screw 157 or the like into an insertion hole 153a provided in the plate-shaped portion 153 and an insertion hole 18b formed in the fixed portion 18, which is part of the frame of the main body 1. The insertion hole 153a and the insertion hole 18b are aligned by inserting a temporary fixing claw 156 provided on the door hinge 152 into a positioning hole 18a formed in the fixed portion 18. The positioning hole 18a is formed so as to open forward in the front-rear direction. This makes it easy to insert the temporary fixing claw 156 of the door hinge 152 into the positioning hole 18a from the front side of the dishwasher 100.

With this rotational configuration of the door section 15, when the door section 15 is to be removed from the main body section 1 for maintenance or the like, the lower front panel 11D is removed from the frame, and the door hinge 152 exposed to the outside is removed from the main body section 1. More specifically, the door hinge 152 and the door section 15 can be removed as a unit by removing the two screws 157, 157 that secure the door hinge 152 to the fixed section 18. When the door section 15 is attached to the main body section 1, the temporary fixing claws 156 of the door hinge 152 attached to the door section 15 are inserted into the positioning holes 18a formed in the fixed section 18, and the door hinge 152 is temporarily fixed to the fixed section 18. In this state, the insertion holes 153a and 18b are aligned in a straight line in the front-to-rear direction, so that by screwing the screw 157 through the insertion holes 153a and 18b, the door section 15 integrated with the door hinge 152 can be fixed to the main body section 1. The screw 157 can be screwed in from the front side of the dishwasher 100, making it easy to work with.

In addition, in conventional configurations in which the door section and the hinge section are not integrated, it is necessary to attach the door hinge to the main body section and then assemble the door section to the door hinge, which makes assembly difficult. Compared to such conventional door section rotation configurations, the door section 15 rotation configuration of this embodiment has excellent assembly ease because the door section 15 can be assembled to the main body section 1 simply by attaching the door hinge 152 integrated with the door section 15 to the main body section 1.

Next, the effects of the dishwasher 100 of the above embodiment will be described. As shown in FIG. 3, in the dishwasher 100 of the above embodiment, the components to be maintained, i.e., the rinsing tank 6 and the rinsing pump 7, are arranged in a line in the front-to-back direction (first direction), so that if the rinsing pump 7 is removed from the front side (one side) in the front-to-back direction, the rinsing tank 6 can also be removed from the front side in the front-to-back direction. In addition, since the rinsing pump 7, which is generally smaller in size than the rinsing tank 6, is arranged in the front side in the front-to-back direction relative to the rinsing tank 6, it is easy to access the rinsing tank 6 from the front side in the front-to-back direction after removing the rinsing pump 7. As a result, in a configuration in which the longitudinal direction of the washing tank 20 and the rinsing tank 6 is arranged in the front-to-back direction of the machine room 1A and the washing tank 20 and the rinsing tank 6 are arranged in the left-to-right direction (second direction), the maintainability of the rinsing tank 6 and the rinsing pump 7 from the front side in the front-to-back direction of the machine room 1A can be ensured.

In the dishwasher 100 of the above embodiment, as shown in Figs. 1 and 3, a lower front panel 11D is provided at the front side in the front-to-rear direction of the machine chamber 1A, which opens the internal space of the machine chamber 1A to the outside of the machine chamber 1A. This allows the lower front panel 11D provided at the front side in the front-to-rear direction of the machine chamber 1A to be removed to open the machine chamber 1A, and the rinsing pump 7 and rinsing tank 6 can be removed or installed from the opened portion. In other words, the rinsing tank 6 and rinsing pump 7 can be easily attached and detached.

In the dishwasher 100 of the above embodiment, as shown in FIG. 4, the rinsing tank 6 is disposed with a gap G between it and the bottom 11F of the machine chamber 1A. This allows wiring, for example, to be disposed in the gap G formed between the bottom 11F of the machine chamber 1A and the rinsing tank 6, making effective use of the limited space in the machine chamber 1A. For example, wiring connected to components disposed in the center of the machine chamber 1A, such as the wash pump 5, wash water heater 25A, detergent supply pump 8, and rinse agent supply pump 9, can be passed through the gap G and further connected to the controller 10 through the gap between the exterior panel 11 and the interior panel 2.

In the dishwasher 100 of the above embodiment, as shown in Figs. 4 and 5, the connection port 6b of the rinsing tank 6 in the rinsing pump 7 is formed in the bottom 6a of the rinsing tank 6.

In addition, in the dishwasher 100 of the above embodiment, as shown in Fig. 4, the piping unit (flow path) 68 connected to the connection port 6b is disposed in the gap G between the rinsing tank 6 and the bottom 11F of the machine chamber 1A, allowing the gap G to be effectively utilized.

As shown in FIG. 5, the connection port 6b in the rinsing tank 6 of the dishwasher 100 of the above embodiment is provided with a branching portion 68C that branches into a first flow path 68A that communicates with the rinsing pump 7 and a second flow path 68B that discharges the water stored in the rinsing tank 6 to the outside. In this configuration, the water stored in the rinsing tank 6 is discharged through the connection port 6b formed in the bottom 6a of the rinsing tank 6, so that almost all of the water stored in the rinsing tank 6 can be discharged.

11, in the dishwasher 100 of the above embodiment, the rinsing pump 7 is provided with a second connection part 71a that opens toward the rear side in the front-to-rear direction, and the rinsing tank 6 is provided with a first connection part 68d of the first flow path 68A that opens toward the front side in the front-to-rear direction. In this configuration, the direction in which the rinsing pump 7 is inserted and removed along the front-to-rear direction coincides with the direction in which the rinsing pump 7 is attached to and detached from the rinsing tank 6 via the first flow path 68A, making it easy to attach and detach the rinsing pump 7 to and from the rinsing tank 6.

The dishwasher 100 of the above embodiment is provided with a first rinsing tank fixing part 66 as shown in FIG. 6(A). With this type of first rinsing tank fixing part 66, a wide contact area of the first connecting part 66b with the rinsing tank 6 can be ensured, ensuring strength. In addition, when the rinsing tank 6 is attached to a predetermined position or removed, the rinsing tank 6 can be easily slid along the first connecting part 66b, facilitating the attachment and detachment process.

As shown in Figures 7(A) and 7(B), in the dishwasher 100 of the above embodiment, a clamping portion 65 is provided that clamps the first connecting portion 66b when the rinsing tank 6 is moved from the front to the rear in the front-to-rear direction relative to the first rinsing tank fixing portion 66. In this configuration, the rinsing tank 6 can be fixed to the first rinsing tank fixing portion 66 by the simple operation of simply moving the rinsing tank 6 from the front to the rear in the front-to-rear direction relative to the first connecting portion 66b of the first rinsing tank fixing portion 66.

The dishwasher 100 of the above embodiment is provided with a second rinsing tank fixing part 67 as shown in FIG. 6(B). With this configuration of the second rinsing tank fixing part 67, the area of the second fixing parts 67c, 67c attached to the rinsing tank 6 can be secured to be large, and the rinsing tank 6 can be positioned at a predetermined position by sliding the second connecting part 67b against the inner surface of the bottom 11F of the machine chamber 1A.

In the dishwasher 100 of the above embodiment, the rinsing pump 7 is fixed via the rinsing pump fixing part 75, so that the rinsing tank 6, which is disposed behind the rinsing pump 7 in the front-to-rear direction, is positioned in the front-to-rear direction. This allows the rinsing tank 6 and the rinsing pump 7 to be fixed integrally to the machine chamber 1A by the simple task of fixing the rinsing tank 6 to the inner surface of the bottom 11F of the machine chamber 1A.

As shown in Figures 8 and 9, in the dishwasher 100 of the above embodiment, the valve support part 69A supporting the valve 60B is removably attached to the valve attachment part 69B by a screw 69 that is screwed in from the front side in the front-to-rear direction. This allows the operator to attach the valve 60B to the rinsing tank 6 by attaching and removing the screw 69 from the front side in the front-to-rear direction, making the valve 60B easy to maintain.

As shown in FIG. 8, in the dishwasher 100 of the above embodiment, an overflow section 63 is formed in the front part 6e of the rinsing tank 6, through which water exceeding a predetermined water storage amount in the rinsing tank 6 is discharged. With this configuration, when removing the rinsing tank 6, the hose is removed before or while the rinsing tank 6 is being pulled out to the front in the front-to-rear direction, and when attaching the rinsing tank 6, it is easy to attach the drain hose (not shown) while or after the rinsing tank 6 is being pushed back in the front-to-rear direction.

Although one embodiment has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the invention.

In the above embodiment, the cleaning tank 20 and the rinsing tank 6 are arranged in the machine room 1A so that the front-to-rear direction is the longitudinal direction, and are arranged side by side in the left-to-right direction, but this is not limited to the above. For example, the cleaning tank 20 and the rinsing tank 6 may be arranged in the machine room 1A so that the left-to-right direction is the longitudinal direction, and are arranged side by side in the front-to-rear direction. For example, in a dishwasher 100 in which the side panels 11A on both the left and right ends are removable from the frame of the main body 1, such a modified configuration can ensure maintainability of the rinsing tank 6 and the rinsing pump 7 from the side where the side panels 11A are removed.

<Other Modifications>
In the above embodiment and modified example, the connection port 6b of the rinsing tank 6 is provided on the bottom 6a of the rinsing tank 6, but it may be provided on the front side 6e. Even in this configuration, a connection portion of the flow path member that opens toward the front side in the front-rear direction can be provided, so that connection to the rinsing tank 6 can be easily performed.

In the above embodiment and modified example, the rack rail 23 is formed integrally with the side panels 2A, 2A by extrusion processing, but the rack rail 23 may be formed by attaching other members to the inner surface of the side panels 2A, 2A.
