(embodiment 1)

Hereinafter, embodiment 1 will be described with reference to fig. 1 to 9B.

[1-1. Structure ]

Fig. 1 shows the external appearance of the dish washing machine of embodiment 1. As shown in fig. 1, the dish washing machine 10 of embodiment 1 includes a main body 11, a door 15, and a cover 20.

The main body 11 accommodates a structure such as a washing tub for accommodating and washing objects to be washed such as tableware.

The door 15 opens and closes an opening portion of the front surface of the main body 11. The door 15 is pivotally supported by the main body 11 at a lower portion by a horizontal rotation shaft. The door 15 is opened by rotating in the front-rear direction so that the upper portion falls down toward the front about the rotation axis. The door 15 may be supported by the main body 11 by a horizontal rotation shaft at the upper portion. In this case, the door 15 may be opened by being rotated in the front-rear direction so that the lower portion is pulled up in the front direction. The door 15 may be pivotally supported by the main body 11 by a vertical rotation shaft. In this case, the door 15 can also be rotated in the horizontal direction to be opened. The door 15 may be configured to open and close an opening in a side surface, a rear surface, or a top surface of the main body 11.

The cover 20 is a decorative member for covering at least a part of the outer surface of the main body 11. In the dish washing machine 10 of the present embodiment, the cover 20 is provided to cover the lower portion of the front surface of the main body 11, that is, the lower portion of the door 15. The cover 20 may cover an upper portion of the front surface of the main body 11, or may cover at least a part of the side surface, the rear surface, the top surface, and the bottom surface of the main body 11.

A right upper end portion of the cover 20 is provided with a cover-side discharge port 21 for discharging the gas inside the main body 11 to the outside. The gas inside the main body 11 is mainly air of high temperature and high humidity containing water vapor. The exhaust path is described later.

Fig. 2 is a schematic cross-sectional view of a part of the inside of the dish washing machine of embodiment 1. As shown in fig. 2, the dish washing machine 10 of embodiment 1 includes a main body 11, a washing tank 12, a water supply valve 1, a water diversion mechanism 2, a heater (not shown), a water temperature sensor (not shown), a washing pump 6, a drain pump 7, a drying fan (not shown), and a washing nozzle 9.

The cleaning tank 12 is provided inside the main body 11. A dish basket 14 for accommodating objects to be washed such as dishes 13 is housed in the washing tub 12.

The water supply valve 1 is provided in a path for supplying washing water into the washing tub 12. The washing water is a liquid used for washing and rinsing objects to be washed such as tableware 13 in the dishwasher 10. The water supply side of the water supply valve 1 may be connected to a pipe such as a tap water pipe or may be connected to a water supply tank not shown.

The washing pump 6 and the drain pump 7 are driven to circulate washing water in the washing tub 12 to wash the object to be washed or to drain washing water from the washing tub 12. In fig. 2, the washing pump 6 and the drain pump 7 are separated into separate components, but 1 pump that doubles as the washing drain may be used.

The heater heats the cleaning water in the cleaning tank 12. The water temperature sensor detects the temperature of the washing water in the washing tub 12.

The dish washing machine 10 of embodiment 1 may also have a detergent tank that stores liquid detergent therein. In this case, the detergent pump is driven, so that the liquid detergent stored in the detergent tank is supplied into the cleaning tank 12.

The drying fan blows air for drying in the step of drying the objects to be washed such as the dishes 13. The drying fan is arranged near the heater. By driving the heater also when the drying fan is driven, the heated air can be blown to the object to be cleaned, and drying can be promoted.

The cleaning nozzle 9 is rotatably provided in the cleaning tank 12, and sprays cleaning water to the object to be cleaned from a plurality of spray ports provided on the surface. The water diversion mechanism 2 feeds the washing water supplied from the water supply valve 1 to the plurality of washing nozzles 9.

Fig. 3A shows the exterior of the dish washing machine 10 with the cover of the door 15 removed. A main body side exhaust port 16 for exhausting gas in the main body 11 is provided in a right lower portion of the front surface of the main body 11 of the dish washing machine 10. An air duct 30 for guiding the gas discharged from the cleaning tank 12 to the main body side discharge port 16 is provided at the right side surface portion of the main body 11. The air duct 30 is fixed from the inside of the cleaning tank 12 by screws or the like. A drying fan is provided at the bottom of the rear surface side of the main body 11. In the dish washing machine 10, a drying fan is driven in a step of drying the object to be washed, and outside air is sucked in and blown into the washing tub 12. The high-temperature and high-humidity gas in the cleaning tank 12 is discharged from the main body side discharge port 16 via the air duct 30. Further, left and right seat portions 31 are shown near both side surfaces of the main body 11. The seat 31 is a structure for fixing the cover 20 described later to the main body 11. Fig. 3B is an enlarged view of the broken line portion (seat portion 31) of fig. 3A.

Fig. 4 is a schematic perspective view showing the appearance and the interior of the cover 20. The cover 20 is a plate-like member that covers the lower part of the front surface of the main body 11, and therefore may have a side surface in addition to the front surface. In the present embodiment, the cover 20 has a top surface and a bottom surface in addition to the front surface and the side surfaces in order to improve convenience, aesthetic appearance, and the like in addition to covering the lower portion of the front surface of the main body 11. In the case where the cover 20 has a top surface, the upper surface or the lower surface of the flow path may be integrally formed with the top surface, and the flow path may be a part of the cover 20. In addition, in the case where the cover 20 has a top surface, the appearance of the dish washing machine 10 is covered with the cover, and thus the aesthetic appearance can be improved. Since the strength can be enhanced when the cover 20 has the bottom surface, deformation of the cover 20 can be suppressed even when the front surface is impacted. In addition, in the case where the cover 20 has a bottom surface, the appearance of the dish washing machine 10 is covered with the cover, and thus the aesthetic appearance can be improved. The cover 20 may also have a rear surface.

A flow path 22 is provided in the cover 20, and the flow path 22 is used to guide the gas discharged from the main body side discharge port 16 from the cover side inlet 26 to the cover side discharge port 21. In the present embodiment, the flow path 22 is provided substantially from the rear surface toward the front in front view of the main body 11. The flow path 22 is separated from the space 24 by a partition 23 that partitions the flow path 22 and another space 24 inside the cover 20. The partition 23 may completely partition the flow path 22 and the space 24 so that the gas does not flow between the flow path 22 and the space 24. Alternatively, the partition 23 may partition the flow path 22 and the space 24 so as to allow a part of the gas to flow between the flow path 22 and the space 24. For example, the flow path 22 and the space 24 may be partitioned by ribs. In short, it is sufficient to form a flow path 22 capable of guiding a large part of the gas discharged from the main body side discharge port 16 from the cover side discharge port 26 to the cover side discharge port 21. This makes it possible to more reliably and efficiently discharge the gas discharged from the main body side discharge port 16 to the outside, and thus to suppress inflow of moisture into the main body 11. Further, since the moisture can be prevented from being filled in the entire inside of the cover 20, the condensation of the space 24 in the inside of the cover 20 can be prevented. The flow path 22 may be configured to be capable of exhausting air, or may be provided in a different direction.

An air vent 25 is provided on the bottom surface of the cover 20. Thereby, the moisture flowing into the space 24 can be discharged to the outside. In addition, even if the cover 20 has no bottom surface as described above, it is possible to release moisture to the outside.

The claw portions 28 having a shape protruding inward are provided on the left and right sides of the back side of the top surface of the cover 20, and the insertion openings 29 are provided on the left and right sides of the bottom surface of the cover 20. When both side surfaces of the cover 20 are inserted into the left and right seat portions 31 (fig. 3B) attached to the main body 11, the seat portions 31 are inserted into the insertion openings 29, and the seat upper surface concave portions 31A of the seat portions 31 are fitted into the claw portions 28 of the cover 20, thereby fixing the cover 20 to the main body 11. At this time, as will be described later, the cover side air inlet 26 and the main body side air outlet 16 are connected in an airtight manner. In addition, in the case where the cover 20 does not have the top surface, or the like, the claw portion 28 may be provided on the front surface, the side surface, the bottom surface, or the like of the cover 20.

Fig. 5 shows the appearance of the cover 20 and the partition 23. A part of the lower surface and the side surface of the flow path 22 in the cover 20 is constituted by the partition 23, and a part of the upper surface and the side surface of the flow path 22 is constituted by the cover 20 itself. This reduces the number of parts, which reduces the manufacturing cost and saves space. The upper surface of the cover 20 is visually recognized by the user when the door 15 is opened, and thus, an aesthetic degree is required. By forming the upper surface of the flow path 22 with the cover 20, the aesthetic appearance of the cover 20 can be improved. The cover 20 and the partition 23 may be formed and assembled as separate members. Alternatively, the cover 20 and the partition 23 may be integrally formed.

More than 1 rib 27 is provided along the flow path 22 in the partition 23. This can suppress turbulence of the gas discharged from the main body side discharge port 16 in the flow path 22, and thus can efficiently discharge the gas inside the main body 11 to the outside.

The hood-side discharge port 21 is provided at the right upper end portion of the front surface of the hood 20. This makes it possible to make the hood-side outlet 21 inconspicuous, and thus to improve the aesthetic appearance of the dish washing machine 10. The cover-side outlet 21 may be provided on the left side or the center of the front surface of the cover 20, or may be provided at the lower end of the front surface of the cover 20. The cover-side outlet 21 may be provided on the bottom surface, the top surface, or the side surface of the cover 20. In the case where the cover-side outlet 21 is provided on the side surface of the cover 20, the partition 23 such as a rib may be provided obliquely from the main body-side outlet 16 toward the side surface of the cover 20.

The cover-side discharge port 21 has a rectangular shape whose left-right direction is a lateral length of the longitudinal direction. The shape of the hood-side discharge opening 21 may be a rectangular shape, a square shape, a circular shape, an elliptical shape, or the like. Particularly in the case where the hood-side discharge port 21 is circular, the flow resistance in the flow path 22 can be reduced, and connection can be easily performed. The hood-side discharge ports 21 may be provided in 1 or two or more. A filter such as a mesh or a lattice may be provided in the hood-side outlet 21. This prevents foreign matter and the like from being mixed into the flow path 22 from the outside.

At least one of the cover-side discharge port 21 and the flow path 22 has a width in the lateral direction smaller than that of the cover 20. This can restrict the exhaust passage, and thus the gas inside the main body 11 can be efficiently discharged to the outside.

Fig. 6A is a right side view in vertical section of the periphery of the flow path 22 inside the cover 20. The two-dot chain line indicates the locus of the lower end of the door 15 when the door 15 is opened. The flow path 22 is provided in a smooth curve so as to curve convexly downward in the height direction along the trajectory of the lower end of the door 15. This suppresses the flow resistance in the flow path 22, and thus the gas inside the body 11 can be efficiently discharged to the outside. Further, since the air is discharged obliquely upward from the hood-side outlet 21, condensation on the floor around the dish washing machine 10 can be suppressed. If the exhaust direction is too high, condensation may occur on the front surfaces of the door 15 and the cover 20 of the main body 11, and if the exhaust direction is too low, condensation may occur on the ground in front of the main body 11. By providing the flow path 22 along the rotation locus of the lower end of the door 15, it is possible to exhaust air in the upper and lower directions, and thus it is possible to suppress condensation. Further, since the flow path 22 can be made longer than in the case where the flow path 22 is formed in a straight line, the temperature of the exhaust gas can be reduced.

Since there is a portion in the middle of the flow path 22 that is lower than the hood-side air inlet 26 due to being convexly curved downward in the height direction, even when condensation occurs in the middle of the flow path 22, the condensed water can be received in this portion, and the inflow of liquid from the hood-side air inlet 26 into the interior of the main body 11 can be suppressed. Further, since there is a portion lower than the hood-side outlet 21 in the middle of the flow path 22, it is possible to suppress the liquid from falling outside the dish washing machine 10 from the hood-side outlet 21 even when condensation occurs in the middle of the flow path 22. As will be described later, the gas inside the main body 11 is discharged to the flow path 22 after the humidity and temperature of the gas are reduced by mixing the external gas, and therefore, condensation can hardly occur in the flow path 22. In addition, even when condensation occurs in the flow path 22 as described above, the condensation water can be received in the flow path 22, and therefore, even if the cover 20 does not have a bottom surface, the condensation water does not fall outside the dish washing machine 10.

Since the flow path 22 is provided in a curved shape, the inside of the main body 11 and the main body side outlet 16 can be hardly visually recognized from the cover side outlet 21. This can improve the aesthetic appearance of the dish washing machine 10.

In the structure shown in fig. 6A, since the cover-side outlet 21 is disposed at a position lower than the main body-side outlet 16 (cover-side inlet 26), the vertical width of the cover 20 can be reduced, and the appearance can be improved by giving the impression of a small area to the cover 20. Fig. 6B is a right side view in vertical section of the periphery of the flow path 22 in the cover 20 when the cover-side discharge port 21 is disposed at a position higher than the main body-side discharge port 16. As shown in fig. 6B, the cover-side outlet 21 may be disposed higher than the main body-side outlet 16 (cover-side inlet 26). In this case, the high-temperature gas heated by the heater can be efficiently discharged to the outside.

The upper surface of the flow path 22 is constituted by the upper surface of the cover 20. The upper surface of the cover 20 has a smooth curved shape along the trajectory of the lower end of the door 15. This can improve the aesthetic appearance of the dish washing machine 10.

Fig. 7 is a top view in plan view of a horizontal cross section of the periphery of the flow path 17 on the main body 11 side and the flow path 22 inside the cover 20. The flow path 17 connected to the air duct 30 is formed so as to incline from the right end portion of the main body 11 toward the center in order to guide the gas in the main body 11 toward the main body side discharge port 16. The flow path 22 in the cover 20 is provided so as to be inclined toward the center in the exhaust direction of the main body side exhaust port 16, that is, in the direction of the flow path 17 on the main body 11 side. This can suppress the flow resistance of the flow path 17, the flow path 22, and the connection portion between the flow path 17 and the flow path 22, and thus can efficiently discharge the gas inside the main body 11 to the outside. Further, as shown by the arrows in the figure, the gas containing moisture is discharged obliquely toward the center of the dish washing machine 10, so that the influence of the moisture on the left and right walls, equipment, furniture, and the like of the dish washing machine 10 can be suppressed. Further, since moisture can be spread over a larger range than in the case where the flow path 22 is provided straight from the main body side discharge port 16 (parallel to the side surface of the main body 11), condensation can be suppressed. Further, since the flow path 22 can be made longer than in the case where the flow path 22 is provided straight from the main body side discharge port 16, the temperature of the exhaust gas can be reduced. Further, since the inside of the main body side outlet 16 and the main body 11 can be hardly visually recognized from the cover side outlet 21, the beauty of the dish washing machine 10 can be improved. The flow path 22 may be formed to be inclined from the center toward either one of the right and left end portions, and this structure can also reduce the visibility of the inside of the main body 11.

The width of the cover-side outlet 21 in the lateral direction is wider than the width of the main body-side outlet 16 and the cover-side inlet 26 in the lateral direction. The flow path 22 is provided so as to widen in width from the main body side outlet 16 and the cover side outlet 26 toward the cover side outlet 21. This can spread moisture over a wide range, and thus can suppress condensation. Further, since the flow path 22 can be extended, the temperature of the exhaust gas can be reduced. Similarly, the height of the cover-side outlet 21 in the up-down direction may be higher than the height of the main body-side outlet 16 and the cover-side outlet 26 in the up-down direction. The area of the cover-side outlet 21 may be larger than the areas of the main body-side outlet 16 and the cover-side outlet 26.

The flow path 22 may be provided parallel to the side surface of the main body 11 from the main body side discharge port 16. Alternatively, the flow path 22 may be curved in a plan view from the main body side discharge port 16.

Fig. 8A is a right side view in vertical section of the periphery of the flow path 17 on the main body 11 side and the flow path 22 inside the cover 20. A fan 32 is provided at the right lower portion of the main body 11, and the fan 32 is an example of an air intake device that functions as a mixing portion that mixes air sucked from the outside of the main body 11 with air discharged from the main body 11. When the fan 32 is driven, external air is sucked from the main body side air intake 19 provided at the bottom of the main body 11. The sucked external air flows through the external air flow path 18 to the main body side discharge port 16, and is mixed with the air in the main body 11 flowing through the flow path 17. The outside air is generally lower in humidity and temperature than the air exhausted from the cleaning tank 12. Thus, by mixing the outside air with the air inside the main body 11, the humidity and temperature of the air inside the main body 11 can be reduced and then discharged to the outside. Thus, even if the air in the main body 11 is discharged to the front surface of the dish washing machine 10, the influence of moisture on the surrounding and floor can be reduced. As an example of such an exhaust structure, in fig. 8A, the air having passed through the inside of the main body 11 of the flow path 17 is discharged from the discharge port upper portion 16A, and the outside air having passed through the outside air flow path 18 is discharged from the discharge port lower portion 16B, so that the air is mixed with each other at the main body side discharge port 16. Fig. 8B shows a cross section of the main body 11 side when cut with the X-X cut surface of fig. 8A. Here, as shown in fig. 8B, the flow path 17 and the outside air flow path 18 are divided by the discharge port upper portion 16A and the discharge port lower portion 16B. The area of the discharge port lower portion 16B is larger than the area of the discharge port upper portion 16A. By making the outlet lower portion 16B for discharging the outside air flowing through the outside air flow path 18 larger than the outlet upper portion 16A for discharging the inside air of the main body 11 flowing through the flow path 17, the humidity and temperature of the inside air can be reduced more efficiently. However, the above-described internal gas and external gas may be discharged in a mixed state at the hood-side discharge port 21, and the arrangement of the internal gas discharge port and the external gas discharge port may be appropriately combined up and down, left and right, and the like.

Fig. 9A shows the range illustrated in fig. 9B. Fig. 9A is a right side view of the same vertical section as fig. 6A and 6B. Fig. 9B is an enlarged view of the range indicated by the broken line of fig. 9A. As described above, the cover 20 is fixed to the main body 11 by inserting both side surfaces thereof into the seat portion 31 of the main body 11. At this time, if there is a manufacturing deviation between the cover 20 and the main body side outlet 16, a gap may be generated between the cover side inlet 26 and the main body side outlet 16, and the gas containing moisture may leak. Thus, in the dish washing machine 10 of the present embodiment, the main body side outlet 16 and the hood side outlet 26 are connected to each other by the seal 33 for maintaining the air-tightness therebetween. The seal 33 is a lip seal provided with a lip 35 on the front surface side, that is, on the outer side (the side farther from the flow path) of the cover 20 side. The seal 33 is made of a material having elasticity. The inner surface 34 of the seal 33 on the front surface side (the side closer to the flow path) is inclined so as to be inclined inward as going outward, that is, toward the upstream side of the flow path, and is smoothly connected to the lip 35. Further, a notch 36 is provided on the inner side of the inner end of the lip 35, and the lip 35 is easily fallen down to the inner side. In such a configuration, the face 34 of the seal 33 smoothly guides the cover-side inlet 26 when the cover 20 is inserted, and therefore the main body-side outlet 16 and the cover-side inlet 26 can be easily connected. When the cover 20 is inserted, as shown by the broken line in fig. 9B, the cover-side air inlet 26 falls down to the inside and enters the inside. The front end portion of the lip 35 is in point or line contact with the lower surface of the cover side 26 when the cover 20 is inserted therein. The upper surface of the lip 35 may be configured to be in surface contact with the lower surface of the cover side inlet 26. The elastic force to be recovered by the lip 35 is used to maintain the airtight seal between the main body side outlet 16 and the cover side inlet 26. This allows the seal 33 to absorb variations in manufacturing of the cover 20 and the main body side discharge port 16, and thus can improve robustness. Further, the flow of the gas containing moisture into the inside of the main body 11 where the electric component is provided can be suppressed.

The one-dot chain line in fig. 9B shows the shape of the flow path 17 on the main body 11 side and the flow path 22 on the cover 20 side which are smoothly connected. The inner surface 37 of the seal 33 has an inclination inclined inward (toward the center of the flow path) as it goes inward, so that the flow path 17 on the main body 11 side and the flow path 22 on the cover 20 side are smoothly connected. This reduces the flow resistance, and thus the gas inside the main body 11 can be efficiently discharged to the outside.

[1-2. Action ]

Hereinafter, the operation and operation of the dish washing machine 10 configured as described above will be described. The user opens the door 15 and places objects to be washed such as dishes 13 in the dish basket 14 of the washing tub 12. After setting the operation program by the operation unit (not shown), the user operates a start button (not shown) to start the cleaning operation. The control unit of the dish washing machine 10 sequentially executes a washing process, a rinsing process, and a drying process based on an operation program.

In the cleaning step, the control unit operates the water supply valve 1 to supply water to the cleaning tank 12, and supplies a predetermined amount of cleaning water to the cleaning tank 12. Here, when the dishwasher 10 has a detergent tank, the control unit drives the detergent pump to supply the liquid detergent into the washing tub 12. Next, the control unit drives the cleaning pump 6 to spray the cleaning water from the cleaning nozzle 9, thereby circulating the cleaning water. The control unit circulates the cleaning water and energizes a heater, not shown, to heat the cleaning 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 a predetermined temperature.

In the rinsing step, the control unit drives the washing pump 6 in the same manner as in the washing step to spray fresh washing water from the washing nozzle 9. The control unit repeats the rinsing operation a predetermined number of times. In the final rinsing operation, the control unit heats the cleaning water by the heater to perform the heated rinsing. This heats the object to be cleaned and the inside of the cleaning tank 12, thereby promoting evaporation of water in the drying step.

In the drying step, the control unit controls the drying fan and the heater to heat the outside air introduced into the cleaning tank 12 and to discharge the moist air in the cleaning tank 12 through the air duct 30, thereby drying the object to be cleaned. At this time, the control unit drives the fan 32 to mix the outside air with the humid air, and discharges the mixture to the outside through the hood-side outlet 21. The control unit performs the drying process for a predetermined time, and ends the washing operation of the dish washing machine 10.

[1-3. Effect etc. ]

As described above, in the present embodiment, the dish washing machine 10 includes: a cleaning tank 12 for cleaning an object to be cleaned; a main body 11 which houses the cleaning tank 12; and a cover 20 covering at least a portion of the outer surface of the main body 11. The main body 11 includes a main body side exhaust port 16 for exhausting gas from the main body 11. The cover 20 includes: a hood-side discharge port 21 for discharging the gas discharged from the main body-side discharge port 16 to the outside; and a partition 23 for partitioning the flow path 22 from another space 24 inside the cover 20, the flow path 22 being for guiding the gas discharged from the main body side discharge port 16 to the cover side discharge port 21. This makes it possible to more reliably and efficiently discharge the gas discharged from the main body side discharge port 16 to the outside, and thus to suppress inflow of moisture into the main body 11. Further, since the moisture is prevented from being filled in the entire inside of the cover 20, the condensation in the space 24 inside the cover 20 can be prevented.

In the present embodiment, the gas discharged from the main body 11 is discharged from the main body side discharge port 16 after mixing the air sucked from the outside of the main body 11. This can reduce the humidity and temperature of the discharged gas, and thus can reduce the influence on the surrounding area and the ground.

In the present embodiment, at least a part of the partition 23 is constituted by the cover 20. This reduces the number of parts, which reduces the manufacturing cost and saves space. Further, the aesthetic appearance of the cover 20 can be improved.

In the present embodiment, 1 or more ribs 27 are provided in the flow path 22 along the flow path 22. This can suppress turbulence of the gas discharged from the main body side discharge port 16 in the flow path 22, and thus can efficiently discharge the gas inside the main body 11 to the outside.

In the present embodiment, the dish washing machine 10 includes a door 15 for opening and closing the opening of the main body 11, wherein the door 15 is opened and closed so as to rotate about a rotation axis, and the flow path 22 is provided along a rotation locus of an end portion of the door 15. This suppresses the flow resistance in the flow path 22, and thus the gas inside the body 11 can be efficiently discharged to the outside. Further, since the flow path 22 can be extended, the temperature of the exhaust gas can be reduced.

In the present embodiment, the door 15 opens and closes the opening of the front surface of the main body 11, the cover 20 is provided at the lower portion of the front surface of the main body 11, and the flow path 22 is provided along the rotation locus of the lower end of the door 15. This suppresses the flow resistance in the flow path 22, and thus the gas inside the body 11 can be efficiently discharged to the outside. Further, since the air is discharged obliquely upward from the hood-side outlet 21, condensation on the floor around the dish washing machine 10 can be suppressed. Further, since the flow path 22 can be extended, the temperature of the exhaust gas can be reduced.

In the present embodiment, the upper surface of the cover 20 has a shape such as to follow the rotation locus of the end of the door 15. This can improve the aesthetic appearance of the dish washing machine 10.

In the present embodiment, the upper surface of the partition 23 is constituted by the upper surface of the cover 20. This reduces the number of parts, which reduces the manufacturing cost and saves space. Further, the aesthetic appearance of the cover 20 can be improved.

In the present embodiment, the cover-side discharge port 21 is provided in an upper portion of the front surface of the cover 20. This makes it possible to make the hood-side outlet 21 inconspicuous, and thus to improve the aesthetic appearance of the dish washing machine 10.

In the present embodiment, the flow path 22 is provided so as to discharge the gas obliquely upward from the hood-side discharge port 21. This can prevent coagulation on the floor around the dish washing machine 10.

In the present embodiment, the flow path 22 is provided along the discharge direction of the main body side discharge port 16. This can spread moisture over a wide range, and thus can suppress condensation. Further, since the flow path 22 can be extended, the temperature of the exhaust gas can be reduced.

In the present embodiment, the lateral width of the cover-side discharge port 21 in the right-left direction is larger than the lateral width of the main body-side discharge port 16 in front view. The area of the hood-side discharge port 21 is larger than the area of the discharge port upper portion 16A. This can spread moisture over a wide range, and thus can suppress condensation. Further, since the flow path 22 can be extended, the temperature of the exhaust gas can be reduced.

In the present embodiment, the main body side discharge port 16 and the flow path 22 are connected via a seal 33. This allows the seal 33 to absorb variations in manufacturing of the cover 20 and the main body side discharge port 16, and thus can improve robustness. Further, the flow of the gas containing moisture into the inside of the main body 11 where the electric component is provided can be suppressed.

In the present embodiment, the inner surface 37 of the seal 33 has an inclination 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 the flow resistance, and thus the gas inside the main body 11 can be efficiently discharged to the outside.
