Summary of the Invention

Problems to be Solved by the Invention

[0004] In such a cleaning machine, there may be a case where the cleaning tank is also arranged in the same direction (first direction) as the extending direction of the rinsing tank. However, in this case, since the cleaning tank extends to one side in the first direction, it becomes difficult to arrange the rinsing pump on one side of the cleaning tank in the first direction as in the conventional case. Therefore, the problem is that the maintainability of the rinsing pump and the rinsing tank cannot be ensured.

[0005] Therefore, an object of the present invention is to provide a washing machine capable of ensuring the maintainability of a rinsing tank and a rinsing pump from one side in the first direction of a machine room in a configuration where the longitudinal directions of a washing tank and a rinsing tank are arranged to be the first direction of the machine room and the washing tank and the rinsing tank are arranged side by side in the second direction.

Means for Solving the Problems

[0006] The washing machine of the present invention includes a washing tank for storing washing water used for washing an object to be washed, a washing pump for sending out the washing water to a washing chamber for accommodating the object to be washed, a rinsing tank for storing rinsing water used for rinsing the object to be washed, a rinsing pump for sending out the rinsing water to the washing chamber, and forms a space extending in a first direction and a second direction orthogonal to the first direction when viewed from the vertical direction, and a machine room disposed below the washing chamber. The washing tank and the rinsing tank are arranged such that the first direction is the longitudinal direction, and are arranged in the machine room so as to be side by side in the second direction. The rinsing pump is detachably arranged in the machine room on one side in the first direction with respect to the rinsing tank detachable from the machine room and in a line in the first direction with respect to the rinsing tank.

[0007] In the washing machine having this configuration, members to be maintained, that is, the rinsing tank and the rinsing pump, are arranged side by side in a line in the first direction. Therefore, if the rinsing pump is taken out from one side in the first direction, the rinsing tank can also be taken out from one side in the first direction. Further, since the rinsing pump, which is generally smaller in size than the rinsing tank, is arranged on one side in the first direction with respect to the rinsing tank, 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 where the longitudinal directions of the washing tank and the rinsing tank are arranged to be the first direction of the machine room and the washing tank and the rinsing tank are arranged side by side in the second direction, the maintainability of the rinsing tank and the rinsing pump from one side in the first direction of the machine room can be ensured.

[0008] In the washing machine of the present invention, a cover that opens the above space to the outside of the machine room may be provided on one side in the first direction in the machine room. In this configuration, the cover provided on one side in the first direction of the machine room is removed to open the machine room, and the rinsing pump and the rinsing tank can be taken out or attached from the opened portion. That is, the attachment and detachment of the rinsing tank and the rinsing pump can be facilitated.

[0009] In the washing machine of the present invention, the rinsing tank may be arranged with a gap between it and the bottom of the machine room. In this configuration, for example, wiring or the like can be arranged in the gap formed between the bottom of the machine room and the rinsing tank.

[0010] In the washing machine of the present invention, the connection port connected to the rinsing pump in the rinsing tank may be formed at the bottom of the rinsing tank. In this configuration, almost all of the water stored in the rinsing tank can be used for rinsing the object to be washed, and the effective water volume in the rinsing tank can be ensured. Further, in this configuration, by arranging the flow path connected to the connection port in the gap between the rinsing tank and the bottom of the machine room, the above gap can be effectively utilized.

[0011] In the washing machine of the present invention, a branch portion that branches into a first flow path communicating with the rinsing pump and a second flow path for discharging the water stored in the rinsing tank to the outside may be provided at the connection port of the rinsing tank. In this configuration, since the water stored in the rinsing tank is discharged through the connection port formed at the bottom of the rinsing tank, almost all of the water stored in the rinsing tank can be discharged.

[0012] In the washing machine of the present invention, the rinsing pump has a connection portion that opens toward the other side in the first direction. In the rinsing tank, a flow path member is provided that extends from the connection port in the rinsing tank as a base end to the tip end toward one side in the first direction and opens toward one side in the first direction. The connection portion and the tip end of the flow path member may be detachably connected. In this configuration, since the insertion / removal direction of the rinsing pump along the first direction and the attachment / detachment direction of the rinsing tank via the rinsing pump and the flow path member coincide, the attachment / detachment of the rinsing pump to / from the rinsing tank becomes easy.

[0013] The washing machine of the present invention further includes a first rinsing tank fixing portion provided on the inner surface of the bottom of the machine room and supporting the rinsing tank from below. The first rinsing tank fixing portion has a pair of first extending portions extending in the vertical direction, a first connecting portion extending in the second direction and connecting one ends of the pair of first extending portions to each other, and a pair of first fixing portions provided at the other ends of the pair of first extending portions, respectively. The first connecting portion supports the rinsing tank from below, and the pair of first fixing portions may be fixed to the inner surface of the bottom of the machine room. In this configuration, a wide contact area of the first connecting portion with respect to the rinsing tank can be ensured, so that the strength can be ensured. Also, when attaching or detaching the rinsing tank to / from a predetermined position, the rinsing tank can be stably and easily slid with respect to the first connecting portion, so that the attachment / detachment operation becomes easy.

[0014] In the washing machine of the present invention, on the outer surface of the bottom of the rinsing tank, a sandwiching portion is formed that extends in the first direction and sandwiches the first connecting portion between the outer surface of the bottom of the rinsing tank. The sandwiching portion may be formed so as to sandwich the first connecting portion when the rinsing tank is moved from one side to the other side in the first direction with respect to the first rinsing tank fixing portion. In this configuration, the rinsing tank can be fixed to the first rinsing tank fixing portion by a simple operation of moving the rinsing tank from one side to the other side in the first direction with respect to the supporting portion of the first rinsing tank fixing portion.

[0015] The washing machine of the present invention further includes a second rinsing tank fixing portion, which is a member separate from the first rinsing tank fixing portion, provided on the inner surface of the bottom of the machine room, and supporting the rinsing tank from below. The second rinsing tank fixing portion has a pair of second extending portions extending in the vertical direction, a second connecting portion extending in the second direction and connecting one ends of the pair of second extending portions, and a pair of second fixing portions respectively provided at the other ends of the pair of second extending portions. Each of the pair of second fixing portions is fixed to the outer surface of the bottom of the rinsing tank, and the second connecting portion may be placed on the inner surface of the bottom of the machine room. With this configuration, a wide area of the second fixing portion attached to the rinsing tank can be ensured, the second connecting portion can be stably slid on the inner surface of the machine room, and the rinsing tank can be positioned at a predetermined position.

[0016] The washing machine of the present invention further includes a rinsing pump fixing portion for fixing a rinsing pump connected to a rinsing tank fixed to the first rinsing tank fixing portion to the inner surface of the bottom of the machine room. The rinsing pump fixing portion may be detachably provided on the inner surface of the bottom of the machine room. With this configuration, by fixing the rinsing pump via the rinsing pump fixing portion, the rinsing tank arranged on the other side of the rinsing pump in the first direction is positioned in the first direction. Thereby, the rinsing tank and the rinsing pump can be integrally fixed to the machine room by a simple operation of fixing the rinsing tank to the inner surface of the bottom of the machine room.

[0017] The washing machine of the present invention further includes a rinsing valve detachably provided on the rinsing tank and switching the presence or absence of water supply to the rinsing tank, a rinsing valve support portion supporting the rinsing valve, and a rinsing valve attachment portion provided on the rinsing tank and detachably attaching the rinsing valve support portion. The rinsing valve support portion in a state of supporting the rinsing valve may be detachably attached to the rinsing valve attachment portion by a screw screwed from one side in the first direction. With this configuration, an operator can attach or remove the screw from one side in the first direction to attach the rinsing valve to the rinsing tank, so the maintainability of the rinsing valve is excellent.

[0018] In the dishwasher of the present invention, a discharge portion for discharging water exceeding a predetermined water storage amount is formed in the rinsing tank, and the discharge portion may be formed on a surface constituting one side in the first direction in the rinsing tank. With this configuration, it becomes easy to attach and detach the drainage hose to and from the discharge portion when attaching and detaching the rinsing tank in the first direction.

Note that the second flow path 68B is usually fixed to the outer surface of the front side portion 6e of the rinsing tank 6, for example, in a state where 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.

[0049] As shown in FIGS. 5, 8, and 9, the first flow path 68A extends from the connection port 6b of the rinsing tank 6 to the tip toward the front side in the front-rear direction. The tip of the first flow path 68A has a first connection portion 68d that opens toward the front side in the front-rear direction. A second connection portion (connection portion) 71a formed at the suction port 71 of the rinsing pump 7 is detachably connected to the first connection portion 68d. For example, the first connection portion 68d and the second connection portion 71a are connected by inserting (fitting) the tip of the first connection portion 68d into the opening of the second connection portion 71a. An O-ring is disposed on the inner peripheral surface of the second connection portion 71a and is in liquid-tight contact with the outer peripheral surface of the first connection portion 68d.

[0050] The rinsing pump 7 is detachably fixed to the inner surface of the bottom 11F of the machine room 1A by a rinsing pump fixing portion 75. The rinsing pump 7 is attached to the machine room 1A in such a state that the opening direction of the suction port 71 opens toward the back side in the front-rear direction and the opening direction of the discharge port 72 opens toward the left side in the left-right direction. The rinsing pump fixing portion 75 has a plate-like portion that protrudes forward in the front-rear direction from the lower end of the rinsing pump 7, and the plate-like portion 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 by the rinsing pump fixing portion 75 immediately behind the lower front panel 11D.

[0051] The rinsing tank 6 is formed with an overflow portion 63 through which water exceeding a predetermined water storage capacity is discharged. A drain hose (not shown) is connected to the overflow portion 63. The water flowing out from the overflow portion 63 is configured to be drained, via the drain hose, into, for example, the storage portion 22 of the cleaning tank 20 in the machine room 1A or drained outside the machine. The overflow portion 63 is formed in the front side portion 6e (the surface constituting one side in the first direction) that constitutes the front side in the front-rear direction in the rinsing tank 6. A valve 60B for controlling the inflow of water from the water supply pipe 60 is detachably provided in the rinsing tank 6. The valve 60B is detachably attached to the outer surface of the left side portion 6c of the rinsing tank 6 by a valve support portion (rinsing valve support portion) 69A and a valve attachment portion (rinsing valve attachment portion) 69B, and is connected to a valve connection portion 6d provided in the left side portion 6c of the rinsing tank 6.

[0052] The valve support portion 69A is formed of a material such as stainless steel and is attached to the valve 60B. The valve support portion 69A is formed with a fixing surface 69Aa that is a surface perpendicular to the front-rear direction by bending. The valve attachment portion 69B is formed of a material such as stainless steel and is detachably provided on the outer surface of the left side portion 6c of the rinsing tank 6. The valve attachment portion 69B is formed with a fixing surface 69Ba that is a surface perpendicular to the front-rear direction by bending. The valve attachment portion 69B supports the valve support portion 69A in a state where the valve 60B is supported. The fixing surface 69Aa of the valve support portion 69A in a state where the valve 60B is supported is detachably attached to the fixing surface 69Ba of the valve attachment portion 69B by a screw 69 screwed in from the front side in the front-rear direction.

[0053] Here, for example, when performing maintenance or the like, the procedure for removing the rinsing pump 7 and the rinsing tank 6 from the machine room 1A will be described. First, remove the lower front panel 11D from the frame to open the inside of the machine room 1A to the outside. Next, remove the screw 69 that fixes the valve support portion 69A and the valve mounting portion 69B, and remove the valve 60B from the valve connection portion 6d. Since the screw head of the screw 69 faces forward in the front-rear direction, work can be performed from the front of the machine room 1A.

[0054] Next, remove the rinsing pump fixing portion 75 from the bottom 11F of the machine room 1A. Specifically, remove the screw (not shown) that attaches the rinsing pump fixing portion 75 to the bottom 11F of the machine room 1A. As a result, the rinsing pump 7 and the rinsing pump fixing portion 75 can be integrally removed from the machine room 1A. Next, remove the rinsing pump 7 from the rinsing tank 6. Specifically, by pulling the rinsing pump 7 forward, the second connection portion 71a of the rinsing pump 7 fitted into the first connection portion 68d of the first flow path 68A is withdrawn from the first connection portion 68d. Thereby, the connection between the first connection portion 68d of the first flow path 68A and the second connection portion 71a of the rinsing pump 7 is released.

[0055] Next, after removing the drain hose connected to the overflow portion 63 of the rinsing tank 6, pull the rinsing tank 6 forward. As a result, the outer surface of the bottom 6a of the rinsing tank 6 slides on 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 on the inner surface of the bottom 11F of the machine room 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 withdrawn from the insertion portion 66e of the first rinsing tank fixing portion 66. Thereby, the fixing (positioning) of the rinsing tank 6 to the machine room 1A is released. And the rinsing tank 6 can be removed from the machine room 1A.

[0056] Next, the procedure for installing the rinsing pump 7 and the rinsing tank 6 in the machine room 1A will be described. Place the rinsing tank 6 with the second rinsing tank fixing portion 67 attached to the outer surface of the bottom portion 6a on the inner surface of the bottom portion 11F of the machine room 1A, and push it out toward the rear side in the front-rear direction. As a result, the outer surface of the bottom portion 6a of the rinsing tank 6 slides on 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 on the inner surface of the bottom portion 11F of the machine room 1A. At this time, push out the rinsing tank 6 so that the clamping portion 65c of the clamping portion 65 attached to the outer surface of the bottom portion 6a of the rinsing tank 6 is inserted into the insertion portion 66e of the first rinsing tank fixing portion 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 by the outer surface of the bottom portion 6a of the rinsing tank 6 and the clamping portion 65c of the clamping portion 65. That is, the rinsing tank 6 is fixed (positioned) with respect to the machine room 1A.

[0057] Next, attach a drain hose to the overflow portion 63 of the rinsing tank 6, and attach the rinsing pump 7 with the rinsing pump fixing portion 75 attached to the bottom portion 11F of the machine room 1A. Specifically, after aligning the first connection portion 68d of the first flow path 68A and the second connection portion 71a of the rinsing pump 7 in a straight line in the front-rear direction, push the rinsing pump 7 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, attach the rinsing pump fixing portion 75 to the bottom portion 11F of the machine room 1A with screws (not shown). As a result, the rinsing pump 7 is fixed to the machine room 1A, and the movement of the rinsing tank 6 toward the front side in the front-rear direction is restricted. Next, fix the valve support portion 69A with the valve 60B fixed to the valve mounting portion 69B, and connect the valve 60B to the valve connection portion 6d. Then, attach the lower front panel 11D to the frame.

[0058] As shown in FIGS. 12 to 13, the door unit 15 includes a handle 15A and a door body 15B. The door body 15B includes a first door panel 151A disposed on the outer side OS (see FIG. 14) which is the opposite side of the cleaning chamber 1B side when attached to the main body portion 1, and a second door panel 151B disposed on the inner side IS (see FIG. 14) which is the cleaning chamber 1B side in the front-rear direction. The first door panel 151A and the second door panel 151B are formed of a material such as stainless steel.

[0059] As shown in FIGS. 12 and 14, standing portions 151Ad standing upright from the main surface 151Ac are formed on the left and right outer edges of the first door panel 151A. 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 disposed 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 welding location W between the flange portion 151Bb and the flange portion 151Ae may be provided intermittently or continuously. In the door unit 15 of the present embodiment in which the first door panel 151A and the second door panel 151B are formed by welding, even when a torsional force acts, it will not be twisted, and the rigidity of the door unit 15 can be increased.

[0060] The handle 15A extends in the left - right direction, and on the outer side described above, a gripping portion 15Ac that an operator can grip is formed. The lower end portion 15Aa of the handle 15A is attached to the upper end portion of the door body 15B (the first door panel 151A). At the lower end portion of the handle 15A, a claw portion 15Ab that can be inserted into a long hole 151Ab formed in the upper end portion 151Aa of the first door panel 151A is formed. In a state where the claw portion 15Ab is inserted into the long hole 151Ab, if the handle 15A is slid in the direction of the long hole with respect to the door body 15B, the claw portion 15Ab and the lower end portion 15Aa will sandwich the upper end portion 151Aa, and the handle 15A and the door body 15B will be fixed. Further, both left and right ends of the handle 15A are fixed to the second door panel 151B of the door body 15B by left and right screws 15Ad, 15Ad.

[0061] As shown in FIGS. 15 to 18, the door portion 15 is attached via a door hinge 152 attached to the main body portion 1. The door hinge 152 has a plate - like portion 153, a rotating portion 154A, and a screw 154B. The plate - like portion 153 constitutes a portion that is attached to the main body portion 1 as will be described in detail later. The rotating portion 154A is provided on the plate - like portion 153 and is a hinge pin that rotatably supports the stopper 155. The screw 154B functions as a retaining means to prevent the stopper 155 rotatably provided on the rotating portion 154A from coming out of the rotating portion 154A. In a state where the door hinge 152 is attached to the main body portion 1, the stopper 155 rotates around an axis A extending in the left - right direction and the horizontal direction with respect to the rotating portion 154A. With such a configuration, the door portion 15 can rotate around the axis A. In the present embodiment, the door portion 15 and the door hinge 152 are integrally formed.

[0062] The plate-shaped portion 153 is formed in a plate shape. The plate-shaped portion 153 is designed to improve its strength (rigidity) by forming a throttle. The stopper 155 is also formed in a plate shape like the door hinge 152 and is fixed to the door body 15B. In the dishwasher 100 of the present embodiment, since the plate-shaped stopper 155 is configured to be rotatable with respect to the plate-shaped plate-shaped portion 153 via the rotating portion 154A, the rotating structure in the door portion 15 can be configured to be compact and thin. As a result, as shown in FIG. 18, it becomes 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.

[0063] The plate-shaped portion 153 is attached to the main body portion 1. The attachment of the plate-shaped portion 153 to the fixed portion 18 is performed by inserting a screw 157 or the like through an insertion hole 153a provided in the plate-shaped portion 153 and an insertion hole 18b formed in the fixed portion 18 which is a part of the frame of the main body portion 1. The alignment of the insertion hole 153a and the insertion hole 18b is performed 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 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.

[0064] According to the rotation configuration of the door unit 15 with such a structure, when removing the door unit 15 from the main body unit 1 during maintenance or the like, the lower front panel 11D can be removed from the frame, and the door hinge 152 exposed to the outside can be removed from the main body unit 1. More specifically, if the two screws 157, 157 fixing the door hinge 152 to the fixed portion 18 are removed, the door hinge 152 and the door unit 15 can be integrally removed. Further, when attaching the door unit 15 to the main body unit 1, the temporary fixing claws 156 of the door hinge 152 attached to the door unit 15 are inserted into the positioning holes 18a formed in the fixed portion 18, and the door hinge 152 is temporarily fixed to the fixed portion 18. And in this state, since the insertion hole 153a and the insertion hole 18b are aligned in a straight line in the front-rear direction, if the screw 157 is screwed so as to pass through the insertion hole 153a and the insertion hole 18b, the door unit 15 integrated with the door hinge 152 can be fixed to the main body unit 1. The screwing of the screw 157 at this time can be performed from the front side of the dishwasher 100, so the workability is excellent.

[0065] Also, in the conventional configuration where the door unit and the hinge unit are not integrated, it is necessary to attach the door hinge to the main body unit and then assemble the door unit to the door hinge, and the assemblability is poor. Compared with such a conventional rotation configuration of the door unit, according to the rotation configuration of the door unit 15 of the present embodiment, the door unit 15 can be assembled to the main body unit 1 only by attaching the door hinge 152 integrated with the door unit 15 to the main body unit 1, so the assemblability is excellent.

[0066] 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, members to be maintained, that is, the rinsing tank 6 and the rinsing pump 7, are arranged side by side in the front-rear direction (first direction). Therefore, if the rinsing pump 7 is taken out from the front side (one side) in the front-rear direction, the rinsing tank 6 can also be taken out from the front side in the front-rear direction. Further, since the rinsing pump 7, which is generally smaller in size than the rinsing tank 6, is arranged on the front side of the rinsing tank 6 in the front-rear direction, it is easy to access the rinsing tank 6 from the front side in the front-rear direction after removing the rinsing pump 7. As a result, the longitudinal directions of the washing tank 20 and the rinsing tank 6 are arranged to be the front-rear direction of the machine room 1A, and in the configuration where the washing tank 20 and the rinsing tank 6 are arranged side by side in the left-right direction (second direction), the maintainability of the rinsing tank 6 and the rinsing pump 7 from the front side in the front-rear direction of the machine room 1A can be ensured.

[0067] In the dishwasher 100 of the above embodiment, as shown in FIGS. 1 and 3, in the machine room 1A, a lower front panel 11D that opens the internal space of the machine room 1A to the outside is provided on the front side in the front-rear direction. Thereby, the lower front panel 11D provided on the front side in the front-rear direction of the machine room 1A can be removed to open the machine room 1A, and the rinsing pump 7 and the rinsing tank 6 can be taken out or attached from the opened portion. That is, the attachment and detachment of the rinsing tank 6 and the rinsing pump 7 can be facilitated.

[0068] In the dishwasher 100 of the above-described embodiment, as shown in FIG. 4, the rinsing tank 6 is disposed with a gap G therebetween from the bottom 11F of the machine room 1A. As a result, wiring or the like can be disposed in the gap G formed between the bottom 11F of the machine room 1A and the rinsing tank 6, so that the limited space in the machine room 1A can be effectively utilized. For example, wiring connected to components disposed at the center of the machine room 1A such as the cleaning pump 5, the cleaning water heater 25A, the detergent supply pump 8, and the rinse agent supply pump 9 can be passed through the gap G and further connected to the controller 10 through the space between the exterior panel 11 and the interior panel 2.

[0069] In the dishwasher 100 of the above-described embodiment, as shown in FIGS. 4 and 5, the connection port 6b of the rinsing tank 6 in the rinsing pump 7 is formed at the bottom 6a of the rinsing tank 6.
