Summary of the Invention

Problems to be Solved by the Invention

[0006] In the dishwasher disclosed in Patent Document 1, the water inlet is fixed to the main body, so when refilling, it is necessary to fill another container with water and carry it to the water inlet, which is inconvenient. In addition, since the hose and pump for supplying water from the water tank to the washing tank are attached to the water tank, the water tank itself cannot be removed from the main body, which presents a problem as it is difficult to clean.

[0007] This disclosure provides technology for improving the convenience of dishwashers. [Means for solving the problem]

[0008] The dishwasher in this disclosure comprises a washing tank for washing items to be washed, a main body housing the washing tank, and a water storage tank detachably provided to the main body below the washing tank for storing water supplied to the washing tank. The water storage tank is provided with a water inlet for supplying the water stored in the water storage tank into the interior of the water storage tank. [Effects of the Invention]

[0009] According to this disclosure, the convenience of dishwashers can be improved. [Brief explanation of the drawing]

[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, unnecessarily detailed descriptions may be omitted in some cases. For example, detailed descriptions of well-known matters or redundant descriptions of substantially the same configurations may be omitted in some cases.

[0012] Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims by these.

[0013] (Embodiment 1) Hereinafter, Embodiment 1 will be described with reference to Figure 1 to Figure 16.

[0014] [1-1. Structure] Figure 1 is a perspective view showing the exterior of the dishwasher 40 according to Embodiment 1. Figure 2 is a perspective view showing the exterior of the dishwasher 40 with the water tank 5 extended. Figure 3 is a partially enlarged view of the exterior of the dishwasher 40 with the water tank 5 extended. Figure 4 is a schematic cross-sectional view of the dishwasher 40 as seen from the rear. Figure 5 is a schematic cross-sectional view of the dishwasher 40 as seen from the side.

[0015] The dishwasher 40 comprises a main body 1, a washing tub 2, a door 3, a base frame 4, a water storage tank 5, and a water supply pump 12.

[0016] The main body 1 houses components such as a washing tank 2 for washing items to be washed, such as dishes. The base frame 4 covers components such as a water storage tank 5 and a water supply pump 12, which are located in the lower part of the interior of the main body 1.

[0017] The washing tank 2 is located inside the main body 1 and contains the items to be washed, such as dishes.

[0018] Door 3 opens and closes the opening on the front of the main body 1. Door 3 is pivotally supported on the main body 1 at its lower part by a horizontal pivot axis. Door 3 opens by rotating in the front-to-back direction around the pivot axis, with the upper part tilting forward.

[0019] The water storage tank 5 stores the water supplied to the washing tank 2. The water storage tank 5 is detachably mounted on the main body 1 below the washing tank 2. This reduces the burden on the user because the water-filled water storage tank 5 does not need to be lifted all the way to the top of the main body 1 when attaching it to the main body 1. It also improves user convenience as even short people can work at a position lower than their eye level. As shown in Figure 2, the water storage tank 5 is configured to be detachable from the main body 1 by pulling it forward. This makes it easy to attach and detach the water storage tank 5 regardless of the installation location of the dishwasher 40, thus improving user convenience. It also makes it easier to clean the water storage tank 5, further improving user convenience. A water storage tank front plate 23 is provided on the front of the water storage tank 5 when it is attached to the main body 1.

[0020] As shown in Figure 3, guide sections 14 are provided on both sides of the lower part of the main body 1 to guide the water storage tank 5 when attaching or detaching it. This improves the convenience for the user when attaching or detaching the water storage tank 5.

[0021] Grooves or recesses may be provided on either or both the bottom surface of the water storage tank 5 and the top surface of the bottom of the main body 1. This reduces the contact area between the bottom surface of the water storage tank 5 and the top surface of the bottom of the main body 1, thereby reducing the frictional force when attaching or detaching the water storage tank 5. Either or both the bottom surface of the water storage tank 5 and the top surface of the bottom of the main body 1 may be made of a material with a low coefficient of static friction and a low coefficient of dynamic friction. This also reduces the frictional force when attaching or detaching the water storage tank 5. With such a configuration, the attachment and detachment of the water storage tank 5 can be made easier, thereby improving user convenience.

[0022] The water supply pump 12 supplies water stored in the water storage tank 5 to the washing tank 2.

[0023] The water storage tank 5 is provided with a water supply cap 7 for opening and closing a water supply hole for supplying water to the inside of the water storage tank 5. When the water storage tank 5 is attached to the main body 1, the water supply cap 7 connects the inside of the water storage tank 5 to the piping on the main body 1 side leading to the water supply pump 12. In other words, when the water storage tank 5 is removed from the main body 1, the water supply cap 7 functions as a shut-off valve, and when the water storage tank 5 is attached to the main body 1, it functions as a connection to the water supply pump 12 for supplying water to the washing tank 2. This prevents water from leaking from inside the water storage tank 5 when the user is carrying the water storage tank 5 to fill it with water, thereby improving user convenience. In addition, since the water supply cap 7 also serves as the connection to the water supply pump 12, the number of parts can be reduced, which can reduce the size and manufacturing cost of the dishwasher 40. Note that the water supply cap 7 may have only one of the functions of a shut-off valve or a connection to the water supply pump 12.

[0024] The water supply cap 7 has a water supply cap lever 9 for rotating the water supply cap 7 to open and close it.

[0025] The water supply cap 7 has a suction port 11 for drawing up water stored in the water storage tank 5. The suction port 11 extends in the outer diameter direction of the water supply hole. The suction port 11 is configured to face the bottom side of the water storage tank 5 when the water supply cap 7 closes the water supply hole and the water storage tank 5 is attached to the main body 1. This allows the water stored inside the water storage tank 5 to be drawn up to the bottom.

[0026] A water tank holding part 13 for securing the water tank 5 to the main body 1 is provided on the bottom of the main body 1 and on the bottom surface of the water tank 5 when the water tank 5 is attached to the main body 1. Details of the water tank holding part 13 will be described later.

[0027] Figure 6 is a schematic cross-sectional view of the water storage tank 5 from the side. Figure 6 shows a cross-section at the location of the water storage tank holding part 13. Figure 7 is a perspective view of the bottom of the main body 1 and the water storage tank 5. Figure 8 is a cross-sectional view of the bottom of the main body 1 and the water storage tank 5 from the front. Figure 9 is a magnified view of a portion of the dashed line in Figure 8.

[0028] The water tank holding section 13 has a water tank holding projection 17 provided on the bottom of the main body 1 and a water tank holding recess 18 provided on the bottom surface of the water tank 5 when the water tank 5 is attached to the main body 1. The water tank holding projection 17 is provided so that its upper surface protrudes from its surroundings. The water tank holding projection 17 is flexible and configured to be displaceable in the vertical direction. The front side of the upper surface of the water tank holding projection 17 is sloped so that the front side is lower and the back side is higher. Therefore, when the water tank 5 is pushed in to attach it to the main body 1, the upper surface of the water tank holding projection 17 is pressed against the bottom surface of the water tank 5 and the water tank holding projection 17 sinks downward, so that the water tank 5 can be pushed in further. When the water tank 5 is pushed in until the recessed portion 18 for holding the water tank is directly above the protruding portion 17 for holding the water tank, the protruding portion 17 returns upward and engages with the recessed portion 18. The protruding portion 17 for holding the water tank is equipped with a leaf spring, which biases it to prevent the engagement between the protruding portion 17 and the recessed portion 18 from disengaging. As a result, the water tank 5 is fixed to the main body 1, so that even if the main body 1 vibrates, moves, or tilts due to external forces, the water tank 5 will not slide forward and detach from the main body 1. The upper surface of the protruding portion 17 for holding the water tank is sloped so that the front is higher and the back is lower. Therefore, when the water tank 5 is pulled forward to remove it from the main body 1, the upper surface of the protruding portion 17 for holding the water tank is pressed against the bottom surface of the water tank 5, causing the protruding portion 17 to sink downward, allowing the water tank 5 to be pulled out. The biasing force of the leaf spring of the water tank holding projection 17 may be determined considering how much the water tank 5 should be fixed to the main body 1 and how easy it is to pull out the water tank 5.

[0029] As shown in Figures 7 and 9, tank rails 21 are provided on both the left and right sides of the upper surface of the bottom of the main body 1 to support the water storage tank 5 and allow it to slide back and forth. As shown in Figure 9, protrusions 22 are provided on both the left and right sides of the bottom of the water storage tank 5. When the water storage tank 5 is held by the water storage tank holder 13, the protrusions 22 come into contact with the tank rails 21. This reduces the contact area between the bottom of the water storage tank 5 and the upper surface of the bottom of the main body 1, thereby reducing the frictional force when attaching and detaching the water storage tank 5. With this configuration, the attachment and detachment of the water storage tank 5 can be made easier, thereby improving user convenience.

[0030] Figure 10 is a perspective view of the water storage tank 5 when it is attached to the main body 1. The water storage tank 5 has a water inlet 19 provided on the side facing the main body 1 when the water storage tank 5 is attached to the main body 1. The water inlet 19 includes a water inlet hole 6 and a water inlet cap 7 for opening and closing the water inlet hole 6. The water inlet cap 7 has a water inlet cap lever 9 for rotating and opening the water inlet cap 7, and a suction port 11 for drawing up water stored in the water storage tank 5. The water storage tank 5 has a protrusion 10 provided near the water inlet 19. Details of the water inlet cap lever 9 and the protrusion 10 will be described later.

[0031] Figure 11 is a front view of the water storage tank 5 while it is being carried. Figure 12 is a perspective view of the water storage tank 5 while it is being carried.

[0032] The water storage tank 5 has handles 16 formed by recesses on both sides when the water inlet 19 is facing upwards. This makes it easier to grip the water storage tank 5, thereby improving user convenience. Furthermore, since it can be gripped and carried with the water inlet 19 facing upwards, it prevents the water inlet cap 7 from coming off and water leaking from the water inlet hole 6 while the user is carrying the water storage tank 5.

[0033] Since the front plate 23 of the water storage tank is flat, when the water supply cap 7 is placed facing upwards to supply water into the water storage tank 5 from the water supply hole 6, as shown in Figures 11 and 12, it acts as the bottom plate of the water storage tank 5. This allows water to be supplied into the water storage tank 5 in a stable state.

[0034] The water storage tank 5 has a drain hole 15 at the bottom when the water inlet 19 is facing upwards. This allows water accumulated at the bottom of the water storage tank 5 to drain out when the user is filling the tank with water, thus preventing water from leaking out when the user is carrying the water storage tank 5 or when they change their grip on the water storage tank 5 to attach it to the main body 1.

[0035] Figure 13 is a perspective view of the water storage tank 5 when it is attached to the main body 1. Figure 14 is a perspective view of the water storage tank 5 when the check valve 20 provided in the air intake port 8 has been removed.

[0036] The water storage tank 5 has an air intake hole 8 located on the top surface when the water storage tank 5 is attached to the main body 1, and at the top when water is supplied to the inside of the water storage tank 5 from the water supply hole 6. A check valve 20 is provided in the air intake hole 8. The check valve 20 may be a duckbill valve or the like. This allows water to be stored up to the top of the water storage tank 5. It also prevents water from leaking out of the air intake hole 8 when the water storage tank 5 is being carried.

[0037] Figures 15 and 16 are side views of the main body 1 with the water storage tank 5 attached to the main body 1.

[0038] Figure 15 shows the state in which the water supply cap 7 is attached to the water supply hole 6 but not closed. Since the length of the water supply cap lever 9 is longer than the distance between the side of the water supply cap 7 and the bottom surface of the main body 1, if you try to attach the water storage tank 5 to the main body 1 with the water supply cap 7 not closed, the water supply cap lever 9 will hit the bottom surface of the main body 1, making it impossible to attach the water storage tank 5 to the main body 1. This prevents the water storage tank 5 from being attached to the main body 1 with the water supply cap 7 not closed.

[0039] Figure 16 shows the water supply cap 7 in the closed position. When the water supply cap lever 9 is rotated clockwise to rotate the water supply cap 7, the water supply cap lever 9 comes into contact with the protrusion 10 of the water storage tank 5. The water supply cap lever 9 is configured to close the water supply hole 6 when the water supply cap 7 is rotated until the water supply cap lever 9 comes into contact with the protrusion 10. This allows the user to properly close the water supply cap 7, thereby improving user convenience. When the water supply cap 7 is closed, the water supply cap lever 9 is configured not to protrude from the bottom surface of the water storage tank 5. This allows the water storage tank 5 to be attached to the main body 1 with the water supply cap 7 properly closed.

[0040] As shown in Figure 10, the suction port 11 on the water supply cap 7 is configured to face the bottom of the water storage tank 5 when the water storage tank 5 is attached to the main body 1, by rotating the water supply cap 7 until the water supply cap lever 9 contacts the protrusion 10. This allows the water inside the water storage tank 5 to be drawn up to the bottom.

[0041] In the example shown in Figure 16, the protrusion 10 is located near the center of the water supply cap 7, so when the water supply cap lever 9 contacts the protrusion 10, the water supply cap lever 9 is at an angle to the edge of the water storage tank 5. With this configuration, even if the water supply cap 7 is not completely closed and the water supply cap lever 9 is slightly protruding from the bottom of the water storage tank 5, when the water storage tank 5 is attached to the main body 1, the water supply cap lever 9 is pressed against the bottom of the main body 1 and rotates until the entire water supply cap lever 9 does not protrude from the bottom of the water storage tank 5, thereby ensuring that the water supply cap 7 is completely closed. In addition, the suction port 11 can be reliably positioned to face the bottom of the water storage tank 5, so that the water inside the water storage tank 5 can be drawn up to the bottom. The water supply cap lever 9 may also be configured to be parallel to the edge of the water storage tank 5 when it contacts the protrusion 10. The water supply cap lever 9 may be configured to be at any angle with respect to the side of the water storage tank 5 when it contacts the protrusion 10.

[0042] [1-2. Operation] The operation and function of the dishwasher 40, configured as described above, will now be explained. The user opens the door 3 and places the dishes and other items to be washed into the washing tub 2. The user fills the water tank 5 with water and attaches it to the bottom of the main unit 1. The user sets the operating course on the control panel (not shown) and then starts the washing operation by operating the start button (not shown). The control unit of the dishwasher 40 executes the washing, rinsing, and drying processes in order based on the operating course.

[0043] During the washing and rinsing processes, the control unit operates the water supply pump 12 to draw water from inside the water storage tank 5 and supply it to the washing tank 2 to wash the objects to be cleaned.

[0044] When the water level inside the water storage tank 5 falls below a predetermined amount, the control unit notifies the user. The user removes the water storage tank 5 from the main unit 1, removes the water supply cap 7, and fills the water storage tank 5 with tap water or other water. After filling the water storage tank 5, the user closes the water supply cap 7 and reattaches the water storage tank 5 to the main unit 1.

[0045] [1-3. Effects, etc.] As described above, in this embodiment, the dishwasher 40 comprises a washing tank 2 for washing items to be washed, a main body 1 that houses the washing tank 2, and a water storage tank 5 that is detachably attached to the main body 1 below the washing tank 2 and stores water supplied to the washing tank 2. The water storage tank 5 is equipped with a water supply hole 6 for supplying water stored in the water storage tank 5 into the inside of the water storage tank 5. This makes it easy to attach and detach the water storage tank 5 and supply water, thereby improving user convenience. Furthermore, it makes it easy to clean the water storage tank 5, further improving user convenience. In addition, when attaching the water-filled water storage tank 5 to the main body 1, it is not necessary to lift it all the way to the top of the main body 1, thus reducing the burden on the user. Furthermore, even short people can work at a position lower than their eye level, further improving user convenience.

[0046] Furthermore, in this embodiment, the water inlet 19 has a water inlet hole 6 and a water inlet cap 7 that opens and closes the water inlet hole 6. The water inlet cap 7 functions as a shut-off valve when the water storage tank 5 is removed from the main body 1, and functions as a connection to the water supply pump 12 for supplying water to the washing tank 2 when the water storage tank 5 is attached to the main body 1. This prevents water from leaking out of the water storage tank 5 when the user is carrying the water storage tank 5 to fill it with water, thereby improving user convenience. In addition, since the water inlet cap 7 also serves as the connection to the water supply pump 12, the number of parts can be reduced, which can reduce the size and manufacturing cost of the dishwasher 40.

[0047] Furthermore, in this embodiment, the water storage tank 5 has an air intake hole 8 located on the top surface when the water storage tank 5 is attached to the main body 1, and at the top when water is supplied to the inside of the water storage tank 5 from the water supply hole 6, and a check valve 20 provided in the air intake hole 8. This allows water to be stored up to the top of the water storage tank 5. In addition, it is possible to prevent water from leaking out of the air intake hole 8 when the water storage tank 5 is being carried.

[0048] Furthermore, in this embodiment, the water inlet 19 has a water inlet hole 6 and a water inlet cap 7 that opens and closes the water inlet hole 6. The water inlet cap 7 has a water inlet cap lever 9. The water storage tank 5 has a protrusion 10 provided near the water inlet 19. The water inlet cap lever 9 is configured to close the water inlet hole 6 by rotating the water inlet cap 7 until the water inlet cap lever 9 contacts the protrusion 10. This allows the user to properly close the water inlet cap 7, thereby improving user convenience.

[0049] Furthermore, in this embodiment, the water supply cap 7 has a suction port 11 for drawing up water stored in the water storage tank 5. The suction port 11 is configured to face the bottom of the water storage tank 5 when the water storage tank 5 is attached to the main body 1, by rotating the water supply cap 7 until the water supply cap lever 9 contacts the protrusion 10. This allows the water inside the water storage tank 5 to be drawn up to the bottom.

[0050] Furthermore, in this embodiment, the length of the water supply cap lever 9 is longer than the distance between the side of the water supply cap 7 and the bottom surface of the main body 1. This configuration ensures that if the water supply cap 7 is not rotated until the water supply cap lever 9 contacts the protrusion 10, attempting to attach the water storage tank 5 to the main body 1 will cause the water supply cap lever 9 to hit the bottom surface of the main body 1. This prevents the water storage tank 5 from being attached to the main body 1 while the water supply cap 7 is not closed.

[0051] (Embodiment 2) Embodiment 2 will be described below with reference to Figures 17 to 20.

[0052] [2-1. Structure] Figure 17 is a perspective view showing the exterior of the dishwasher 40 with the water tank 5 extended. Figure 18 is a perspective view of the water tank 5 while it is being carried. Figure 19 is a schematic cross-sectional view of the water tank 5 from the side. Figure 20 is a magnified view of a portion of the dashed line area in Figure 19.

[0053] The dishwasher 40 of Embodiment 2 is equipped with a stopper recess 25 and a stopper protrusion 26 to secure the water storage tank 5 so that it does not slide forward and detach from the main body 1 when the water storage tank 5 is attached to the main body 1. The other configurations, operation, and effects are the same as those of Embodiment 1.

[0054] As shown in Figure 17, the stopper recess 25 is provided on the front upper surface of the leg portion 24 located at the bottom of the main body 1. As shown in Figure 18, the stopper projection 26 is provided on the front bottom surface when the water storage tank 5 is attached to the main body 1. When the water storage tank 5 is attached to the main body 1, the stopper projection 26 engages with the stopper recess 25. When a large amount of water is stored inside the water storage tank 5, the load on the water storage tank 5 acting in the direction of gravity is large, so the stopper projection 26 strongly engages with the stopper recess 25. This fixes the water storage tank 5 in place so that it does not slide forward and detach from the main body 1. When the amount of water stored inside the water storage tank 5 decreases, the load on the water storage tank 5 acting in the direction of gravity decreases, so the engagement between the stopper projection 26 and the stopper recess 25 weakens. This makes it easy to pull the water storage tank 5 forward. The rear side of the lower surface of the stopper projection 26 is sloped. This reduces friction between the stopper projection 26 and the upper surface of the bottom of the main body 1 when inserting the water storage tank 5 into the main body 1, making it easier to insert the water storage tank 5 into the main body 1. A recess may be provided on the bottom surface of the water storage tank 5, and a projection may be provided on the leg portion 24 of the main body 1. In addition, the water storage tank 5 may be fixed to the main body 1 by any other mechanism.
