Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments will be described in detail with reference to the drawings. However, a more detailed description may be omitted as necessary. For example, a detailed description of well-known matters or a redundant description of substantially the same configuration may be omitted.

[0011] 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.

[0012] <00,00083>(Embodiment 1) Hereinafter, Embodiment 1 will be described with reference to FIGS. 1 to 9B.

[0013] [1-1. Configuration] FIG. 1 shows the appearance of a dishwasher according to Embodiment 1. As shown in FIG. 1, the dishwasher 10 according to Embodiment 1 includes a main body 11, a door 15, and a cover 20.

[0014] The main body 11 houses components such as a washing tank for accommodating and washing objects to be washed such as dishes.

[0015] The door 15 opens and closes an opening at the front of the main body 11. The door 15 is pivotally supported by the main body 11 by a horizontal rotation axis at the lower part. The door 15 is opened by rotating in the front-rear direction so that the upper part falls forward around the rotation axis. The door 15 may be pivotally supported by the main body 11 by a horizontal rotation axis at the upper part. In this case, the door 15 may be opened by rotating in the front-rear direction so that the lower part is pulled up forward. The door 15 may be pivotally supported by the main body 11 by a vertical rotation axis. In this case, the door 15 may be opened by rotating in the horizontal direction. The door 15 may be provided to open and close an opening on the side surface, rear surface, or top surface of the main body 11.

[0016] The cover 20 is a decorative component for covering at least a part of the outer surface of the main body 11. In the dishwasher 10 of the present embodiment, the cover 20 is provided to cover the lower part of the front surface of the main body 11, that is, below the door 15. The cover 20 may be provided to cover the upper part of the front surface of the main body 11, or may be provided to cover at least a part of the side surface, rear surface, top surface, and bottom surface of the main body 11.

[0017] A cover-side exhaust port 21 for discharging the gas inside the main body 11 to the outside is provided at the upper right end of the cover 20. The gas inside the main body 11 is mainly high-temperature and high-humidity air containing water vapor. The exhaust path will be described later.

[0018] FIG. 2 is a schematic cross-sectional view of a part inside the dishwasher of Embodiment 1. As shown in FIG. 2, the dishwasher 10 of Embodiment 1 includes a main body 11, a washing tank 12, a water supply valve ①, a water distribution mechanism 2, a heater (not shown), a water temperature sensor (not shown), a washing pump 6, a drainage pump 7, a drying fan (not shown), and a washing nozzle 9.

[0019] The washing tank 12 is provided inside the main body 11. Inside the washing tank 12, a dish basket 14 for placing objects to be washed such as dishes 13 is accommodated.

[0020] The water supply valve ① is provided in the path for supplying washing water into the washing tank 12. Here, the washing water refers to the liquid used for washing and rinsing objects to be washed such as dishes 13 in the dishwasher 10. The water supply side of the water supply valve ① may be connected to a pipe such as a water pipe, or may be connected to a water supply tank not shown.

[0021] The washing pump 6 and the drainage pump 7 are driven to wash the objects to be washed by circulating the washing water in the washing tank 12 or to drain the washing water from the washing tank 12. Although the washing pump 6 and the drainage pump 7 are shown as separate components in FIG. 2, one pump that combines washing and drainage may also be used.

[0022] The heater heats the cleaning water in the cleaning tank 12. The water temperature sensor detects the temperature of the cleaning water in the cleaning tank 12.

[0023] The dishwasher 10 of Embodiment 1 may have a detergent tank for storing liquid detergent inside. In this case, a detergent pump is driven to supply the liquid detergent stored in the detergent tank into the washing tank 12.

[0024] The drying fan blows air for drying during the process of drying items to be washed, such as tableware 13. The drying fan is installed near the heater. By driving the heater when the drying fan is driven, heated air can be blown onto the items to be washed, thereby accelerating drying.

[0025] The cleaning nozzle 9 is rotatably mounted within the cleaning tank 12 and sprays cleaning water onto the object to be cleaned from multiple nozzles on its surface. Furthermore, the water distribution mechanism 2 sends the cleaning water supplied from the water supply valve 1 to the multiple cleaning nozzles 9.

[0026] Figure 3A shows the exterior of the dishwasher 10 with the outer cover of the door 15 removed. A body-side outlet 16 for discharging gas from inside the body 11 is provided on the lower right front of the main body 11 of the dishwasher 10. An air duct 30 is provided on the right side of the main body 11 to guide the gas discharged from the washing tank 12 to the body-side outlet 16. The air duct 30 is fixed from the inside of the washing tank 12 with screws or the like. A drying fan is provided at the bottom of the rear side of the main body 11. In the process of drying the items to be washed, the dishwasher 10 drives the drying fan to take in outside air and blow it into the washing tank 12. The high-temperature, high-humidity gas inside the washing tank 12 is discharged from the body-side outlet 16 via the air duct 30. Also shown are the left and right legs 31 near both sides of the main body 11. The legs 31 are configured to fix the cover 20, which will be described later, to the main body 11. Figure 3B is a magnified view of the wavy line portion (leg portion 31) in Figure 3A.

[0027] Figure 4 is a schematic perspective view showing the exterior and interior of the cover 20. Since the cover 20 is a plate-shaped component that covers the lower part of the front of the main body 11, it is sufficient to have sides in addition to the front. In this embodiment, in addition to covering the lower part of the front of the main body 11, the cover 20 also has a top surface and a bottom surface in addition to the front and sides to improve convenience and design. If the cover 20 has a top surface, the upper or lower surface of the flow path can be molded integrally with the top surface, making the flow path part of the cover 20. Also, if the cover 20 has a top surface, the exterior of the dishwasher 10 is covered by the cover, thus improving its design. If the cover 20 has a bottom surface, its strength can be reinforced, so deformation of the cover 20 can be suppressed even if there is an impact on the front. Also, if the cover 20 has a bottom surface, the exterior of the dishwasher 10 is covered by the cover, thus improving its design. The cover 20 may also have a rear surface.

[0028] A flow path 22 is provided inside the cover 20 to guide the gas discharged from the main body side outlet 16 from the cover side intake port 26 to the cover side outlet 21. In this embodiment, the flow path 22 is provided so as to extend from the back to the front of the main body 11 when viewed from the front. The flow path 22 is separated from another space 24 inside the cover 20 by a partition portion 23. The partition portion 23 may completely separate the flow path 22 and the space 24 so that gas does not flow between the flow path 22 and the space 24. Alternatively, the partition portion 23 may separate the flow path 22 and the space 24 so that some gas flow is permitted between the flow path 22 and the space 24. For example, the flow path 22 and the space 24 may be separated by ribs or the like. In any case, it is sufficient to form a flow path 22 such that most of the gas discharged from the main body side outlet 16 is guided from the cover side intake port 26 to the cover side outlet 21. This allows the gas discharged from the main unit's outlet 16 to be discharged to the outside more reliably and efficiently, thereby preventing moisture from flowing into the main unit 11. Furthermore, it prevents moisture from filling the entire interior of the cover 20, thus preventing condensation from occurring in the internal space 24 of the cover 20. Note that the flow path 22 may be provided in different directions, as long as it is configured to allow exhaust.

[0029] A ventilation hole 25 is provided on the bottom surface of the cover 20. This allows moisture that has entered the space 24 to escape to the outside. Furthermore, as mentioned above, even if the cover 20 does not have a bottom surface, moisture can still be released to the outside.

[0030] On the underside of the top surface of the cover 20, there are convex claw portions 28 on both the left and right sides, and on the bottom surface of the cover 20, there are insertion openings 29 on both the left and right sides. When the cover 20 is inserted into the left and right legs 31 (Figure 3B) attached to the main body 11 on both sides, the legs 31 fit into the insertion openings 29, and the cover 20 is fixed to the main body 11 by the engagement of the recessed portion 31A on the upper surface of the legs 31 and the claw portions 28 of the cover 20. At this time, as will be described later, the air intake port 26 on the cover side and the exhaust port 16 on the main body side are airtightly connected. If the cover 20 does not have a top surface, the claw portions 28 may be provided on the front, sides, or bottom of the cover 20.

[0031] Figure 5 shows the external appearance of the cover 20 and the partition 23. The lower surface and part of the side of the flow path 22 inside the cover 20 are formed by the partition 23, and the upper surface and part of the side of the flow path 22 are formed by the cover 20 itself. This reduces the number of parts, thereby lowering manufacturing costs and saving space. The upper surface of the cover 20 is visible to the user when the door 15 is opened, so aesthetic appeal is required. By forming the upper surface of the flow path 22 with the cover 20, the aesthetic appeal of the cover 20 can be improved. The cover 20 and the partition 23 may be molded separately as separate parts and assembled. Alternatively, the cover 20 and the partition 23 may be molded integrally.

[0032] One or more ribs 27 are provided inside the partition 23 along the flow path 22. This prevents turbulence in the flow path 22 caused by the gas discharged from the main body side outlet 16, thereby allowing the gas inside the main body 11 to be efficiently discharged to the outside.

[0033] The cover-side discharge port 21 is provided at the upper right end of the front surface of the cover 20. This makes the cover-side discharge port 21 less conspicuous, thereby improving the aesthetic design of the dishwasher 10. The cover-side discharge port 21 may also be provided on the left side or in the center of the front surface of the cover 20, or at the lower end of the front surface of the cover 20. The cover-side discharge port 21 may also be provided on the bottom, top, or side surface of the cover 20. If the cover-side discharge port 21 is provided on the side surface of the cover 20, a partition portion 23 such as a rib may be provided diagonally from the main body-side discharge port 16 toward the side surface of the cover 20.

[0034] The cover-side outlet 21 has a horizontally elongated rectangular shape with the left-right direction being its longitudinal direction. The shape of the cover-side outlet 21 may also be a vertically elongated rectangle, square, circle, ellipse, etc. In particular, if the cover-side outlet 21 is circular, the flow resistance in the flow path 22 can be reduced and connection can be made easier. There may be one cover-side outlet 21 or two or more may be provided. A filter such as a mesh or grid may be provided inside the cover-side outlet 21. This prevents foreign matter from entering the flow path 22 from the outside.

[0035] The width in the left-right direction of at least one of the cover-side outlet 21 and the flow path 22 is smaller than the left-right width of the cover 20. This restricts the exhaust path, allowing the gas inside the main body 11 to be efficiently discharged to the outside.

[0036] Figure 6A is a right-side view of the vertical cross-section around the flow path 22 inside the cover 20. The dashed line shows the trajectory of the lower end of the door 15 when it is opened. The flow path 22 is provided in a smooth curve that curves convexly downward in the height direction along the trajectory of the lower end of the door 15. This reduces flow resistance in the flow path 22, allowing the gas inside the main body 11 to be efficiently discharged to the outside. Also, since the gas is discharged diagonally upward from the cover-side outlet 21, condensation on the floor surface around the dishwasher 10 can be suppressed. If the exhaust direction is too high, condensation may occur on the front of the door 15 of the main body 11 or the cover 20, and if the exhaust direction is too low, condensation may occur on the floor surface in front of the main body 11. By providing the flow path 22 along the rotation trajectory of the lower end of the door 15, the exhaust can be directed in a direction that is neither too high nor too low, thus suppressing condensation. Also, since the flow path 22 can be made longer than when it is configured in a straight line, the exhaust temperature can be lowered.

[0037] Because the flow path 22 curves convexly downwards in the height direction, there is a section that is lower than the cover-side air intake 26. Therefore, even if condensation occurs in the flow path 22, this section can collect the condensed water, preventing the liquid from flowing into the main body 11 from the cover-side air intake 26. Also, because there is a section in the flow path 22 that is lower than the cover-side outlet 21, even if condensation occurs in the flow path 22, the liquid can be prevented from dripping outside the dishwasher 10 from the cover-side outlet 21. Furthermore, as will be described later, the gas inside the main body 11 is mixed with outside air to lower its humidity and temperature before being discharged into the flow path 22, so in reality, condensation in the flow path 22 can be made to be almost nonexistent. Moreover, as mentioned above, even if condensation occurs in the flow path 22, the condensed water can be collected within the flow path 22, so even if the cover 20 does not have a bottom surface, the condensed water will not drip outside the dishwasher 10.

[0038] Since the flow path 22 is provided in a curved shape, it is possible to make it difficult to see the main body side outlet 16 and the inside of the main body 11 from the cover side outlet 21. This improves the aesthetic design of the dishwasher 10.

[0039] In the configuration shown in Figure 6A, the cover-side outlet 21 is positioned lower than the main body-side outlet 16 (cover-side intake port 26), which reduces the vertical width of the cover 20 and improves its aesthetic appeal by giving the impression of a smaller surface area. Figure 6B is a view from the right side of the vertical cross-section around the flow path 22 inside the cover 20 when the cover-side outlet 21 is positioned higher than the main body-side outlet 16. As shown in Figure 6B, the cover-side outlet 21 may also be positioned higher than the main body-side outlet 16 (cover-side intake port 26). In this case, the high-temperature gas heated by the heater can be efficiently discharged to the outside.

[0040] The upper surface of the flow path 22 is formed by the upper surface of the cover 20. The upper surface of the cover 20 has a smooth, curved shape that follows the trajectory of the lower end of the door 15. This improves the aesthetic design of the dishwasher 10.

[0041] Figure 7 is a top view of the horizontal cross-section around the flow path 17 on the main body 11 and the flow path 22 inside the cover 20. The flow path 17, which connects from the air duct 30 to guide the gas inside the main body 11 to the main body side outlet 16, is formed diagonally from the right end of the main body 11 toward the center. The flow path 22 inside the cover 20 is provided diagonally toward the center so as to align with the exhaust direction at the main body side outlet 16, that is, the direction of the flow path 17 on the main body 11 side. This reduces flow resistance in the flow path 17, the flow path 22, and their connection points, allowing the gas inside the main body 11 to be efficiently discharged to the outside. Also, as shown by the arrows in the figure, since the moisture-containing gas is discharged diagonally toward the center of the dishwasher 10, the impact of moisture on the left and right walls, equipment, furniture, etc. of the dishwasher 10 can be reduced. In addition, moisture can be diffused over a wider area than when the flow path 22 is provided straight from the main body side outlet 16 (parallel to the side of the main body 11), thus reducing condensation. Furthermore, since the flow path 22 can be made longer than when it is provided straight from the main body side outlet 16, the exhaust temperature can be lowered. Also, since it is made more difficult to see the main body side outlet 16 and the inside of the main body 11 from the cover side outlet 21, the design of the dishwasher 10 can be improved. Note that the flow path 22 may be formed at an angle so as to be directed from the center to either the left or right end, and even with this configuration, the visibility of the inside of the main body 11 can be reduced.

[0042] The width of the cover-side outlet 21 in the left-right direction is wider than the width of the main body-side outlet 16 and the cover-side intake port 26 in the left-right direction. The flow path 22 is provided so as to widen from the main body-side outlet 16 and the cover-side intake port 26 toward the cover-side outlet 21. This allows moisture to be diffused over a wide area, thereby suppressing condensation. In addition, the flow path 22 can be made longer, which can lower the exhaust temperature. Similarly, the height of the cover-side outlet 21 in the vertical direction may be greater than the height of the main body-side outlet 16 and the cover-side intake port 26 in the vertical direction. Also, the area of ​​the cover-side outlet 21 may be larger than the area of ​​the main body-side outlet 16 and the cover-side intake port 26.

[0043] The flow path 22 may be provided parallel to the side surface of the main body 11, starting from the main body side outlet 16. Alternatively, the flow path 22 may be provided in a curved shape when viewed from above, starting from the main body side outlet 16.

[0044] Figure 8A is a view from the right side of a vertical cross-section around the flow path 17 on the main body 11 and the flow path 22 inside the cover 20. A fan 32, which is an example of an intake device that functions as a mixing unit to mix the gas discharged from the main body 11 with air taken in from outside the main body 11, is provided at the lower right of the main body 11. When the fan 32 is driven, outside air is drawn in from the main body side intake port 19 located at the bottom of the main body 11. The drawn-in outside air flows through the outside air flow path 18 to the main body side outlet 16 and is mixed with the gas inside the main body 11 that has flowed in from the flow path 17. The outside air is usually lower in humidity and temperature than the gas discharged from the washing tank 12. Therefore, by mixing the outside air with the gas inside the main body 11, the humidity and temperature of the gas inside the main body 11 can be lowered before being discharged to the outside. This reduces the impact of moisture on the surroundings and floor even when the gas inside the main body 11 is discharged to the front of the dishwasher 10. As an example of such an exhaust structure, Figure 8A shows that the high-temperature, high-humidity gas inside the main body 11 that has passed through the flow path 17 is discharged from the upper part of the outlet 16A, and the outside air that has passed through the outside air flow path 18 is discharged from the lower part of the outlet 16B, so that the air from each is mixed at the outlet 16 on the main body side. Figure 8B shows a cross-section of the main body 11 when cut along the XX cutting plane of Figure 8A. As shown in Figure 8B, the flow path 17 and the outside air flow path 18 are separated by the upper part of the outlet 16A and the lower part of the outlet 16B. The area of ​​the lower part of the outlet 16B is larger than the area of ​​the upper part of the outlet 16A. By making the lower part of the outlet 16B, which discharges the outside air that has flowed through the outside air flow path 18, larger than the upper part of the outlet 16A, which discharges the gas inside the main body 11 that has flowed through the flow path 17, the humidity and temperature of the internal air can be reduced more efficiently. However, the aforementioned internal and external air only need to be exhausted in a mixed state at the cover-side exhaust port 21, and the arrangement of the internal air exhaust port and the external air exhaust port can be combined as appropriate, such as vertically or horizontally.

[0045] Figure 9A shows the area shown in Figure 9B. Figure 9A is a right-side view of a vertical cross-section similar to that in Figures 6A and 6B. Figure 9B is an enlarged view of the area shown by the dashed line in Figure 9A. As mentioned above, the cover 20 is fixed to the main body 11 by inserting both sides into the legs 31 of the main body 11. At this time, if there are manufacturing variations between the cover 20 and the main body side outlet 16, a gap may be created between the cover side intake port 26 and the main body side outlet port 16, potentially causing moisture-containing gas to leak out. Therefore, in this embodiment of the dishwasher 10, the main body side outlet port 16 and the cover side intake port 26 are connected via a packing 33 to maintain airtightness between them. The packing 33 is a lip packing with a lip 35 provided on the front side, i.e., the outside of the cover 20 side (the side farther from the flow path). The packing 33 is made of an elastic material. The inner surface 34 of the front side of the packing 33 (the side closer to the flow path) is sloped so that it slopes inward towards the back, i.e., upstream of the flow path, as it moves outward, allowing for a smooth connection to the lip 35. In addition, a notch 36 is provided on the back side of the inner end of the lip 35, making it easier for the lip 35 to tilt inward. In this configuration, when the cover 20 is inserted, the surface 34 of the packing 33 smoothly guides the cover-side intake port 26, allowing for easy connection between the main body-side outlet port 16 and the cover-side intake port 26. When the cover 20 is inserted, as shown by the dashed line in Figure 9B, the cover-side intake port 26 moves inward, tilting the lip 35 inward. When the cover 20 is inserted all the way in, the tip of the lip 35 makes contact with the lower surface of the cover-side intake port 26 at a point or along a line. The upper surface of the lip 35 may also be configured to make contact with the lower surface of the cover-side intake port 26 over a surface. The elastic force of the lip 35 returning to its original shape maintains airtightness between the main body-side exhaust port 16 and the cover-side intake port 26. This allows the packing 33 to absorb manufacturing variations in the cover 20 and the main body-side exhaust port 16, thereby improving robustness. It also prevents moisture-containing gas from flowing back into the main body 11 where electrical components are located.

[0046] The dashed line in Figure 9B shows the shape that smoothly connects the flow path 17 on the main body 11 side and the flow path 22 on the cover 20 side. The inner surface 37 of the packing 33 is sloped inward (towards the center of the flow path) as it goes further back, so as to smoothly connect the flow path 17 on the main body 11 side and the flow path 22 on the cover 20 side. This reduces flow resistance, so that the gas inside the main body 11 can be efficiently discharged to the outside.

[0047] [1-2. Operation] The operation and function of the dishwasher 10, configured as described above, will now be explained. The user opens the door 15 and places the dishes 13 and other items to be washed into the dish basket 14 of the washing tub 12. 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 10 executes the washing, rinsing, and drying processes in order based on the operating course.

[0048] During the washing process, the control unit operates the water supply valve 1 to supply water to the washing tank 12, supplying a predetermined amount of washing water to the washing tank 12. If the dishwasher 10 has a detergent tank, the control unit drives the detergent pump to supply liquid detergent into the washing tank 12. Subsequently, the control unit drives the washing pump 6 to spray washing water from the washing nozzle 9, circulating the washing water. While circulating the washing water, the control unit energizes a heater (not shown) to heat the washing water. At this time, the control unit detects the temperature of the washing water using a water temperature sensor (not shown). The control unit controls the washing water to reach a predetermined temperature.

[0049] In the rinsing process, the control unit drives the washing pump 6 to spray new washing water from the washing nozzle 9, similar to the washing process. The control unit repeats this rinsing operation a predetermined number of times. In the final rinsing operation, the control unit heats the washing water with a heater to perform heated rinsing. This heats the object being washed and the inside of the washing tank 12, promoting the evaporation of moisture in the drying process.

[0050] During the drying process, the control unit controls the drying fan and heater to heat the outside air introduced into the washing tank 12 while discharging the humid air from the washing tank 12 via the air duct 30, thereby drying the items to be washed. At this time, the control unit drives the fan 32 to mix the humid air with outside air and discharge it to the outside through the cover-side discharge port 21. The control unit performs the drying process for a predetermined time and then terminates the washing operation of the dishwasher 10.

[0051] [1-3. Effects, etc.] As described above, in this embodiment, the dishwasher 10 comprises a washing tank 12 for washing items to be washed, a main body 11 that houses the washing tank 12, and a cover 20 that covers at least a part of the outer surface of the main body 11. The main body 11 is provided with a main body-side outlet 16 for discharging gas from the main body 11.

This reduces flow resistance in the flow path 22, allowing the gas inside the main body 11 to be efficiently discharged to the outside. Also, since the gas is discharged diagonally upward from the cover-side outlet 21, condensation on the floor surface around the dishwasher 10 can be suppressed. Furthermore, since the flow path 22 can be made longer, the exhaust temperature can be lowered.

[0057] Furthermore, in this embodiment, the upper surface of the cover 20 has a shape that follows the rotational trajectory of the end of the door 15. This improves the aesthetic design of the dishwasher 10.

[0058] Furthermore, in this embodiment, the upper surface of the partition 23 is formed by the upper surface of the cover 20. This reduces the number of parts, thereby lowering manufacturing costs and saving space. It also improves the aesthetic design of the cover 20.

[0059] Furthermore, in this embodiment, the cover-side discharge port 21 is provided on the upper part of the front surface of the cover 20. This makes the cover-side discharge port 21 less conspicuous, thereby improving the aesthetic design of the dishwasher 10.

[0060] Furthermore, in this embodiment, the flow path 22 is provided so that gas is discharged diagonally upward from the cover-side outlet 21. This makes it possible to suppress condensation on the floor surface around the dishwasher 10.

[0061] Furthermore, in this embodiment, the flow path 22 is provided so as to be aligned with the discharge direction at the main body side outlet 16. This allows moisture to be diffused over a wide area, thereby suppressing condensation. In addition, the flow path 22 can be made longer, which allows the exhaust temperature to be lowered.

[0062] Furthermore, in this embodiment, the width of the cover-side outlet 21 in the left-right direction when viewed from the front is greater than the width of the main body-side outlet 16. In addition, the area of ​​the cover-side outlet 21 is larger than the area of ​​the upper part 16A of the outlet. This allows moisture to be diffused over a wide area, thus suppressing condensation. Also, the flow path 22 can be made longer, which allows the exhaust temperature to be lowered.

[0063] Furthermore, in this embodiment, the main body side outlet 16 and the flow path 22 are connected via a packing 33. This allows the packing 33 to absorb variations in the manufacturing of the cover 20 and the main body side outlet 16, thereby improving robustness. It also prevents moisture-containing gas from flowing back into the main body 11 where electrical components are located.

[0064] Furthermore, in this embodiment, the inner surface 37 of the packing 33 is sloped to smoothly connect the flow path 17 on the main body 11 side and the flow path 22 on the cover 20 side. This reduces flow resistance, allowing the gas inside the main body 11 to be efficiently discharged to the outside.
