Description

  The present invention relates to a dishwasher. More specifically, the present invention relates to a technique for preventing exhaust from a dishwasher from entering the back side of a kitchen counter.

  2. Description of the Related Art Dishwashers that perform a tableware drying process following a tableware cleaning process have become widespread. The tableware washing | cleaning process said here includes not only the process of wash | cleaning tableware but the process of rinsing tableware after that. In the tableware drying process, external air is blown into the cleaning tank by the blower fan. The air blown into the cleaning tank is heated by the heater to become high-temperature air. The air that has passed through the cleaning tank passes through the discharge path and is discharged to the outside together with the steam in the cabinet and the moisture adhering to the dishes and the cleaning tank. In particular, the exhaust at the start of the tableware drying process is hot and humid.

In many built-in dishwashers incorporated in the system kitchen, the exhaust path opens toward the front of the dishwasher. Hot and humid exhaust is rapidly cooled and condensed when exposed to outside air. Therefore, condensation is likely to occur at the opening (exhaust port) of the exhaust path, and water droplets attached around the exhaust port may fall on the floor surface and wet the floor surface.
A built-in dishwasher is installed directly under the kitchen counter. Since the end portion of the kitchen counter protrudes toward the front side from the dishwasher, the exhaust directly hits the lower surface of the protruding portion of the kitchen counter, so that condensation tends to occur. When condensation occurs on the lower surface of the protruding portion of the kitchen counter, water droplets attached to the lower surface of the protruding portion of the kitchen counter may fall on the floor surface and wet the floor surface.

  The dishwasher of Patent Document 1 includes a substantially cylindrical exhaust port and an exhaust port frame that are inclined upward toward the front of the dishwasher body. The exhaust port frame projects further forward than the exhaust port, and the lower side of the exhaust port frame comes into contact with the main body side from the front end of the lower side of the exhaust port. Since the water droplets adhering to the periphery of the exhaust port frame return into the exhaust port along the lower side of the exhaust port frame, it is possible to prevent the water surface from falling onto the floor surface and getting wet. In addition, if the exhaust frame protrudes forward from the front end of the kitchen counter, it prevents the exhaust from directly hitting the lower surface of the protruding portion of the kitchen counter, and dew condensation is caused by the exhaust hitting the lower surface of the protruding portion of the kitchen counter. Thus, it is possible to prevent water droplets adhering to the surface from falling onto the floor surface and wetting the floor surface.

Japanese Patent Laid-Open No. 11-206681

With the dishwasher of patent document 1, it can prevent that exhaust_gas | exhaustion hits directly the lower surface of the protrusion part of a kitchen counter. However, in the dishwasher of Patent Document 1, it is difficult to prevent a part of the discharged exhaust from entering the gap between the lower surface of the kitchen counter and the dishwasher body. If high-temperature and high-humidity exhaust enters the gap, condensation occurs on the lower surface of the kitchen counter. Since moisture tends to accumulate in this gap, water droplets generated by condensation on the lower surface of the kitchen counter can erode the kitchen counter. This gap is a place where daily care is impossible, and there is a risk that the deterioration of the kitchen counter will proceed secretly.
An object of this invention is to provide the dishwasher which can prevent that the lower surface of a kitchen counter deteriorates when a hot and humid exhaust invades into the lower surface of a kitchen counter.

The dishwasher of this invention is arrange | positioned under the kitchen counter, and wash | cleans and dries tableware. This dishwasher introduces outside air into the washing tank from the introduction path, the introduction path communicating between the inside and outside of the washing tank, the discharge path communicating between the inside and outside of the washing tank, and the washing tank. Blower means for discharging outside air introduced into the discharge path from the discharge path, and is mounted on the upper part of the main body and located above the outlet of the discharge path and covers at least the lower surface of the kitchen counter corresponding to the left and right width of the outlet of the discharge path And a counter cover.
According to the configuration of the present invention, since the lower surface of the protruding portion of the kitchen counter is covered with the counter cover even when the hot and humid exhaust discharged from the outlet of the exhaust path rises, the lower surface of the protruding portion of the kitchen counter It is possible to prevent the exhaust from directly hitting and condensing. Moreover, since the counter cover is attached to the upper part of the dishwasher body, it is possible to prevent the exhaust from entering the gap between the lower surface of the kitchen counter and the dishwasher body. The left and right width of the counter cover is equal to or greater than the left and right width of the outlet of the discharge path. The lower the left and right width of the counter cover is, the more effectively the lower surface of the kitchen counter can be protected.

In the dishwasher of the present invention, an exhaust cover is provided at the outlet of the exhaust path, and the exhaust cover includes an upper member that is a plate member protruding forward from the upper end of the outlet of the exhaust path, and the exhaust path. And a lower member that is a plate member that protrudes forward from the lower end of the outlet and is inclined upward toward the front end, and the front end of the lower member is positioned forward of the front end of the upper member In addition, the counter cover is preferably located behind the front end of the counter cover .
If the dishwasher of the present invention is configured as described above, the direction in which the exhaust discharged from the outlet of the exhaust path flows can be controlled, and the exhaust can be guided to the portion protected by the counter cover. Thereby, it is possible to prevent the exhaust from directly hitting the bottom surface of the protruding portion of the kitchen counter and condensing, and to prevent the exhaust from entering the gap between the bottom surface of the kitchen counter and the main body of the dishwasher.
Further, if the lower member of the exhaust cover is inclined downward from the front end toward the exhaust port, even if the exhaust condenses on the front end of the exhaust cover and water droplets adhere, the water droplets travel along the upper surface of the lower member. Therefore, it is possible to prevent water droplets from falling onto the kitchen floor and getting wet.

Furthermore, in the dishwasher of the present invention, the vicinity of the front end of the counter cover is formed so as to be inclined downward toward a portion located above between the front end of the upper member of the exhaust cover and the front end of the lower member. It is preferable.
In the dishwasher of the present invention, exhaust is guided to the lower surface of the counter cover by the exhaust cover, and condensation forms on the lower surface of the counter cover and water droplets adhere. If the shape of the counter cover is formed as described above, the adhering water droplets are collected in the upper portion between the front end of the upper member of the exhaust cover and the front end of the lower member, and eventually the bottom of the exhaust cover. It falls to the upper surface of the member and is returned to the cleaning tank. That is, even if the exhaust is condensed on the lower surface of the counter cover and water droplets are generated, the location where the water droplets are dropped can be controlled and received on the upper surface of the lower member of the exhaust cover. This protects the underside of the kitchen counter from exhaust and prevents the water from falling onto the kitchen floor and wetting the floor even if the exhaust is condensed and water drops are generated. Can do.

In the dishwasher of this invention, the hydrophilic process may be given to the part located above the front end of the upper member of an exhaust cover, and the front end of a lower member of the lower surface near the front end of a counter cover.
If it is said structure, the water | moisture content in exhaust_gas | exhaustion can be actively condensed in the part to which the hydrophilic process is given. The moisture in the exhaust gas is deprived by the hydrophilic processing portion of the counter cover and decreases, so that it is possible to effectively prevent the exhaust gas from condensing in other portions thereafter.

  According to the dishwasher of the present invention, it is possible to prevent the exhaust from directly hitting the bottom surface of the protruding portion of the kitchen counter and condensing, and the exhaust enters the gap between the bottom surface of the kitchen counter and the main body of the dishwasher. Can be prevented. Thereby, deterioration of the lower surface of the kitchen counter can be prevented.

A dishwasher 10 according to an embodiment embodying the present invention will be described with reference to the drawings.
FIG. 1 shows a part of the dishwasher 10 with the door 15 closed with respect to the main body 12. The door 15 is provided with a handle 15a, an operation panel 16, a lock lever 13, and an exhaust port 18. The operation panel 16 is provided with various buttons and lamps (not shown). By sliding the lock lever 13 in the lateral direction, the door 15 can be locked and unlocked (FIG. 1 shows a state in which the lock lever 13 is disposed at the lock position). A set of exhaust covers 76 is formed at the exhaust port 18. The exhaust cover 76 includes an upper member 72 formed at the upper end of the exhaust port 18 and a lower member 74 formed at the lower end of the exhaust port 18. The exhaust cover 76 will be described in detail later.
The main body 12 supports a cleaning tank (see FIG. 2: 14) through a roller and a rail (not shown) so as to be slidable. When the user puts his hand on the handle 15 a and pulls it forward, the cleaning tank 14 is pulled out from the main body 12 together with the door 15. A counter cover 70 is attached to the front end of the upper portion of the main body 12. The counter cover 70 will also be described in detail later.

  As shown in FIG. 2, the cleaning tank 14 is formed in a box shape with an open top, and a cleaning nozzle 20, a leftover filter 17, a dish basket 61, and the like are mounted therein. The cleaning nozzle 20 includes a tower nozzle portion 23 including an upper nozzle 21 and a lower nozzle 22 and a horizontal nozzle portion 24. The cleaning nozzle 20 has a plurality of injection ports 21a, 22a, and 24a. The leftovers filter 17 is formed in a mesh shape, and is provided to filter out the leftovers washed away from the dishes 17 when the dishes 17 are washed. The leftover filter 17 can be removed from the washing tank 14, and the leftovers filtered off can be discarded. The tableware basket 61 is formed in a shape corresponding to the tableware 19 in order to hold various tableware (large plate, small plate, bowl, cup, ladder, spoon, etc.) 19.

A suction recess 31 is formed at the bottom of the cleaning tank 14. The upper opening of the suction recess 31 is covered with the leftover filter 17. A pump 27 is provided below the bottom surface 39 of the cleaning tank 14. The pump 27 rotates the impeller 28 by a built-in electric motor. The pump 27 can rotate the impeller 28 in one direction and can also rotate in the opposite direction. A portion where the impeller 28 of the pump 27 is disposed and the suction recess 31 are communicated with each other by a suction flow path 32. An electric heater 30 is mounted above the bottom surface 39 of the cleaning tank 14 and is covered with a slat-like cover.
A cleaning nozzle 20 is rotatably attached to the bottom surface 39 of the cleaning tank 14. The cleaning nozzle 20 and the first discharge port 11 of the pump 27 communicate with each other. Some of the plurality of spray ports formed in the cleaning nozzle 20 cause the cleaning nozzle 20 to generate a rotation moment when water is sprayed.

A drain hose 34 is connected to the rear wall 33 of the main body 12. The drain hose 34 and the second discharge port 35 of the pump 27 are communicated with each other by a drain channel 36. The middle of the drainage flow path 36 and the inside of the cleaning tank 14 are communicated by an air vent path 37. A drainage check valve 38 is mounted in the vicinity of the portion of the drainage channel 36 connected to the drainage hose 34. The drainage check valve 38 prevents drainage from flowing backward from the drainage hose 34 to the drainage flow path 36.
A water supply hose 40 is connected to the horizontal portion of the rear wall 33 of the main body 12. The water supply hose 40 may be directly supplied with tap water (cold water) or may be supplied with hot water heated by a water heater.
A water supply valve 41 is attached to the inside of the rear wall 33. The water supply valve 41 is driven by a built-in solenoid to open and close. The inlet 44 of the water supply valve 41 and the water supply hose 40 are communicated with each other by a first water supply channel 42. The outlet 64 of the water supply valve 41 and the inside of the cleaning tank 14 are communicated with each other by the second water supply channel 43.

A water level detector 45 is provided at the lower portion outside the front portion of the cleaning tank 14. The water level detector 45 has a water level chamber 46, a float 47, a bar 48, and a switch 49. The water level chamber 46 communicates with the suction recess 31 by a water level path 50. The float 47 is disposed in the water level chamber 46. The bar 48 is fixed to the float 47 and protrudes upward from the water level chamber 46. The switch 49 is disposed above the bar 48.
A drying fan 52 is attached to the outside of the rear wall 51 of the cleaning tank 14. The drying fan 52 rotates the fan 53 with a built-in motor. The drying fan 52 and the cleaning tank 14 are communicated with each other through a drying path 63. The drying fan 52 is disposed higher than the water level 54 (hereinafter referred to as “normal water level”) when the cleaning water is normally supplied to the cleaning tank 14. Therefore, water can be prevented from entering the drying fan 52.
A thermistor 55 is mounted on the bottom surface 39 of the cleaning tank 14. The thermistor 55 detects the temperature of the water when the cleaning water and the rinsing water are put in the cleaning tank 14, and detects the air temperature when the cleaning water and the rinsing water are not put.
A recess 58 is formed in the bottom surface 57 of the main body 12. Two electrodes of the water leak detection sensor 59 are inserted into the recess 58. When water leaks from the cleaning tank 14 to the outside and the leaked water flows into the recess 58, the electrodes are connected and the water leak detection sensor 59 is turned on.

A controller 60 is mounted in the door 15. The controller 60 includes a CPU, a ROM, a RAM, and the like, and controls the operation of the dishwasher 10. The controller 60 is connected to the operation panel 16, the pump 27, the heater 30, the water supply valve 41, the water level detector 45, the drying fan 52, the thermistor 55, and the water leak detection sensor 59.
A seal lid 56 is disposed above the cleaning tank 14. The seal lid 56 is connected to the cleaning tank 14 by a lifting mechanism (not shown). In a state where the cleaning tank 14 is accommodated in the main body 12, the seal lid 56 is lowered to cover the upper opening of the cleaning tank 14. When the cleaning tank 14 is pulled out from the main body 12, the seal lid 56 rises to open the upper opening of the cleaning tank 14.

  The dishwasher 10 operates in the order of a cleaning process, a rinsing process, and a drying process. When the user turns on the operation start button provided on the operation panel 16, the cleaning process is started. In addition, before starting a washing | cleaning process, the detergent is thrown into the predetermined site | part of the tableware basket 61 by the user. In the cleaning process, the water supply valve 41 is first opened. When the water supply valve 41 is opened, tap water is supplied to the cleaning tank 14 through the water supply hose 40, the first water supply channel 42, and the second water supply channel 43. When the water is supplied, the water level of the cleaning water in the cleaning tank 14 rises. The washing water flows through the suction recess 31 and the water level path 50 and enters the water level chamber 46 of the water detector 45. As the cleaning water level rises, the water level in the water level chamber 46 also rises. When the water level in the water level chamber rises, the float 46 rises. As the float 46 floats, the bar 48 rises with it. When the bar 48 rises and the upper end contacts the switch 49, the water level detector 45 is turned on. When the water level detector 45 is turned on, the water supply valve 41 is closed, whereby the water supply to the cleaning tank 14 is completed. The water level (normal water level 54) when the water level detector 45 is turned on and the water supply to the cleaning tank 14 is finished is slightly higher than that of the heater 30.

When the water supply valve 41 is closed, the pump 27 is cleaned and the heater 30 is turned on. Here, the cleaning operation of the pump 27 means that the impeller 28 of the pump 27 rotates in one direction, sucks cleaning water from the suction recess 31 via the suction flow path 32, and the sucked cleaning water is removed from the cleaning nozzle. This means an operation state to be sent to the No. 20. As described above, the middle of the drainage flow path 36 communicates with the inside of the cleaning tank 14 by the air vent path 37. For this reason, when the pump 27 is performing a cleaning operation, air enters the drainage flow path 36. Further, a part of the drainage channel 36 is formed in an inverted U shape. For this reason, the pump 27 performing the cleaning operation is prevented from sucking the wastewater through the drainage flow path 36.
The washing water sent to the washing nozzle 20 is ejected vigorously from the injection port. The cleaning nozzle 20 is rotated by a rotational moment generated by the ejection of the cleaning water while ejecting the cleaning water. The tableware 19 is washed by the washing water ejected from the ejection port. The washing water that has washed the tableware 19 is again sucked into the pump 27 from the suction recess 31. In this manner, the cleaning water sucked into the pump 27 is sprayed from the spray nozzle of the cleaning nozzle 20 and the circulation sucked into the pump 27 again is repeated. The leftovers washed away from the tableware 19 are filtered out by the leftovers filter 17.
When the heater 30 is turned on, the temperature of the cleaning water increases. The temperature of the washing water is detected by the thermistor 55. The heater 30 is ON / OFF controlled based on the temperature detected by the thermistor 55, and the washing water temperature is maintained within a predetermined range (for example, 45 to 60 ° C.).

  When a predetermined time (for example, 10 minutes) elapses after the cleaning water temperature is maintained within a predetermined range, the heater 30 is turned off and the pump 27 is drained. Here, the drainage operation of the pump 27 means that the impeller 28 of the pump 27 rotates in the other direction, so that the wash water is sucked from the suction recess 31 via the suction flow path 32, and the sucked wash water is discharged into the drainage flow. This means an operation state in which the fuel is discharged to the outside through the passage 36 and the drain hose 34. The drainage operation of the pump 27 ends when a predetermined time (for example, 40 seconds) elapses. The predetermined time is set as a time sufficient to drain all the cleaning water from the cleaning tank 14. When the drainage operation of the pump 27 is completed, air enters the drainage path 36 through the air vent path 37.

  In the rinsing process, the water supply valve 41 is opened and water is supplied to the cleaning tank 14. When water is supplied to the cleaning tank 14 and the water level detector 45 is turned on, the water supply valve 41 is closed, the pump 27 is operated for cleaning, and the heater 30 is turned on. When the pump 27 is operated for rinsing, rinsing water is ejected from the ejection port of the washing nozzle 20 and the tableware 19 is rinsed. The heater 30 that is turned on heats the rinse water to warm water. When a predetermined time (for example, 1 minute) elapses after the cleaning operation of the pump 27 is started, the pump 27 stops. Then, the rinsing water is drained from the cleaning tank 14 by performing the drainage operation of the pump 27. The rinsing process is repeated a predetermined number of times (for example, 5 times).

  In the drying process, the drying fan 52 is operated and the heater 30 is turned on. When the drying fan 52 is operated, external air is sent into the cleaning tank 14 via the drying path 63. The sent air passes through the cleaning tank 14 and is exhausted to the outside through the exhaust port 18. When the heater 30 is turned on, the air temperature in the cleaning tank 14 increases. While the outside air is fed into the cleaning tank 14 and the temperature in the cleaning tank 14 becomes high, the temperature-controlled drying of the tableware 19 is performed. When a predetermined time (for example, 25 minutes) elapses after the temperature-controlled drying of the tableware 19 is started, the heater 30 is turned off and air drying is performed. When a predetermined time (for example, 5 minutes) elapses after the air-drying of the tableware 19 is started, the operation of the fan 52 is stopped and the drying process is ended. A buzzer sounds, the completion of all processes is notified, and the power of the dishwasher 10 is turned off.

In the drying process, the exhaust discharged from the exhaust port 18 is high temperature and contains a lot of moisture. When this hot and humid exhaust comes into contact with the air outside the dishwasher 10, it is cooled and tends to condense. The places where condensation is most likely to occur are the periphery of the exhaust port 18 and the lower surface of the kitchen counter (see FIG. 3: 78) where the exhaust directly hits.
As shown in FIG. 3, in the dishwasher 10 of this embodiment, a set of exhaust covers 76 are formed at the exhaust port 18. The upper member 72 of the exhaust cover 76 is a plate member that protrudes horizontally from the upper end of the exhaust port 18 toward the front (left side in the figure), and the front end portion 72a is bent downward in an arc shape in cross section. The lower surface of the front end portion 72a is subjected to hydrophilic processing. The lower member of the exhaust cover 76 is a plate member that protrudes slightly upward from the lower end of the exhaust port 18 toward the front, and the front end portion 74a is bent upward in a circular arc shape.
A counter cover 70 is attached to the front end of the upper portion of the main body 12. The counter cover 70 is a plate member that extends forward from the main body 12. A fixing portion 70a of the counter cover 70 is fixed to the front end portion 12a at the top of the main body. Following the fixed portion 70a, a horizontal portion 70b extending horizontally forward is formed. Following the horizontal portion 70b, a bent portion 70c is formed which is bent so that the cross-section in the front-rear direction is a gentle V shape. A hydrophilic process is applied to the lower surface of the bent portion 70c. A front end portion 70d extending vertically upward is formed following the bent portion 70c.
As shown in FIG. 1, wall portions 70 e extending vertically downward are formed at the left and right ends of the horizontal portion 70 b and the bent portion 70 c of the counter cover 70. A screw hole 70f that extends long in the front-rear direction is formed in the fixed portion 70a. When the dishwasher 10 is installed, the position of the counter cover 70 is adjusted so that the front end portion 70d contacts the front end surface of the kitchen counter 78, and is fixed to the front end portion 12a of the main body by screws 80. The left and right width of the counter cover 70 is larger than the left and right widths of the exhaust port 18 and the exhaust cover 76. In this embodiment, the left and right widths of the exhaust cover 76 are each 20 mm larger. Further, regarding the length of the counter cover 70 in the front-rear direction, even when the counter cover 70 is protruded forward and fixed, the lower end of the bent portion 70 c is located behind the front end portion 74 a of the lower member 74 of the exhaust cover 76. Even when the counter cover 70 is retracted and fixed to the rearmost position, the lower end of the bent portion 70 c is formed to be positioned forward of the front end portion 72 a of the upper member 72 of the exhaust cover 76. That is, the lower end of the bent portion 70 c of the counter cover 70 is positioned above the front end portion 74 a of the lower member 74 of the exhaust cover 76 and the front end portion 72 a of the upper member 72.

In the drying process, when the operation of the drying fan 52 is started, the hot and humid air in the cleaning tank 14 is pushed out to the exhaust port 18 as shown by the solid line arrow A in FIG. The exhaust gas flows along the upper member 72 and the lower member 74 of the exhaust cover 76.
As indicated by a solid arrow B, when the exhaust comes into contact with the hydrophilic processed portion on the lower surface of the front end portion 72a of the upper member 72, moisture in the exhaust adheres to the hydrophilic processed portion. Moisture in the exhaust gas that has successively adhered to the hydrophilic processed portion eventually becomes water droplets and falls onto the upper surface of the lower member 74 as indicated by the dashed arrow C. Since the lower member 74 is inclined downward toward the cleaning tank side, the water droplets dropped on the upper surface of the lower member 74 flow backward and are returned to the cleaning tank 14 as indicated by a broken arrow D.
Since the front end portion 72a of the lower member 74 is bent upward, the exhaust pushed out to the exhaust port 18 is exhausted upward as indicated by a solid arrow E. The exhaust discharged upward flows toward the bent portion 70 c of the counter cover 70. When the exhaust comes into contact with the hydrophilic processed portion on the lower surface of the bent portion 70c, a part of the moisture in the exhaust adheres to the hydrophilic processed portion. Moisture in the exhaust gas that has successively adhered to the hydrophilic processed portion falls as water droplets and falls onto the upper surface of the lower member 74 as indicated by a broken arrow F. The water droplets falling on the upper surface of the lower member 74 flow backward and return to the cleaning tank 14 as indicated by the broken line arrow D.
On the other hand, the exhaust gas after coming into contact with the hydrophilic processed portion of the bent portion 70 c is divided into a front portion and a rear portion, and flows along the counter cover 70. As indicated by the solid arrow G, the exhaust gas flowing forward flows forward or upward of the kitchen counter 78. As indicated by the solid arrow H, the exhaust gas flowing backward along the horizontal portion 70 b of the counter cover 70 flows downward along the front surface of the door 15 of the dishwasher 10. Exhaust gas after contacting the hydrophilic processed portion of the bent portion 70c has a reduced moisture content because a part of the moisture is removed. For this reason, even after the exhaust gas contacts the bent portion 70c, dew condensation occurs even if it contacts the front end portion 70d of the counter cover 70, the front end surface of the kitchen counter 78, the horizontal portion 70b of the counter cover 70, the front surface of the door 15, or the like. Never do.

In the drying process, the exhaust discharged from the dishwasher is hot and humid. This hot and humid exhaust tends to condense when exposed to the outside air. Condensation due to exhaust is likely to occur around the exhaust port and on the underside of the kitchen counter. The water droplets attached around the exhaust vent fall onto the kitchen floor and wet the floor. Water droplets adhering to the lower surface of the kitchen counter erode and degrade the lower surface of the kitchen counter. In particular, if exhaust enters the gap between the kitchen counter's lower surface and the dishwasher body, it is difficult to clean even though moisture tends to be trapped. There is a risk of progress.
In the dishwasher 10 of this embodiment, the lower surface of the kitchen counter 78 is covered with the counter cover 70. The exhaust cover 76 controls the exhaust so as to rise toward the counter cover 70. Further, the left and right widths of the counter cover 70 are larger than the left and right widths of the exhaust port 18 and the exhaust cover 76, and wall portions 70 e extending downward are formed at the left and right ends of the counter cover 70. Even if the exhaust gas to be raised rises while being diffused, the exhaust gas is guided to the portion protected by the counter cover 70. With such a configuration, it is possible to prevent the exhaust from directly hitting the lower surface of the kitchen counter 78 and to prevent the exhaust from entering the gap between the lower surface of the kitchen counter 78 and the upper surface of the main body of the dishwasher 10.
Further, in the dishwasher 10 of the present embodiment, each of the counter cover 78 and the upper member 72 of the exhaust cover is subjected to hydrophilic processing at the place where the exhaust is most exposed to positively condense moisture in the exhaust, It is possible to reduce the moisture content in the exhaust gas and to prevent dew condensation at other locations. Furthermore, the water droplets thus positively condensed can be collected and returned to the cleaning tank 14. With such a configuration, it is possible to prevent water droplets generated by condensation of the exhaust from falling on the floor surface of the kitchen and wetting the floor surface.

Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.
For example, in this embodiment, the front / rear position adjustment of the exhaust cover 76 is not possible, but the front / rear position adjustment may be possible.
In addition, the technical elements described in the present specification or drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.
