JP 2000-139799 A

  In such a dishwasher, in order to dry the dishes after washing, outside air is sent into the washing cabinet by a fan or the like, and the outside air is heated by a heater arranged in the washing cabinet and applied to the dishes. The water vapor that evaporates is discharged outside the machine. In general, the heater is disposed at the bottom of the washing cabinet in order to serve as water for cleaning and rinsing. However, in the conventional configuration, heat exchange between the outside air sent to the washing cabinet and the heater is not necessarily performed efficiently, and there is a situation where air whose temperature has not sufficiently increased hits the tableware. For this reason, there is a possibility that the tableware that has been warmed by using hot water in the final rinsing process immediately before the drying process is cooled in the drying process and the drying efficiency is lowered. Considering such a situation, in order to completely dry the tableware, the drying operation time has to be set longer, and there is a problem of wasteful consumption of electric power in addition to prolonged operation time.

  The present invention has been made in view of the above points, and the object of the present invention is to efficiently dry the dishes during the drying operation, thereby reducing the drying operation time and power consumption. It is to provide a dishwasher that can.

  According to a fourth aspect of the present invention, in the second or third aspect, a gap is provided between a lower edge portion of the cover and a bottom surface of the cleaning cabinet.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the cleaning chamber is open at the top and can be drawn forward from a casing having the front opened.

  A sixth aspect of the present invention is that in any one of the first to fifth aspects, the air outlet of the air passage formed by the cover is located in the vicinity of the wall surface on the opposite side of the exhaust port provided in the cleaning cabinet. Features.

  The invention of claim 7 is characterized in that, in claim 6, the blower outlet is an upward opening at a position where the heating means is not disposed.

  The invention of claim 8 is characterized in that, in any one of claims 1 to 7, the air passage has an elongated shape in the horizontal direction, and the heating means also has an elongated shape along the air passage.

  The invention of a ninth aspect is characterized in that, in any one of the first to eighth aspects, the cover is made of metal.

  A tenth aspect of the present invention is characterized in that, in any one of the first to ninth aspects, the air blowing means is disposed between a front wall of the cleaning cabinet and a front plate provided on the front surface thereof.

The invention according to claim 11 is a housing having an open front surface, guide rails mounted on the inner side walls of the housing, and can be drawn forward from the housing along the guide rails. A cleaning cabinet having an opening for storing and taking out; an upper lid for closing the upper surface opening of the cleaning cabinet; and a tableware bowl for storing dishes disposed in the cleaning cabinet in parallel with the cleaning cabinet. In a dishwasher comprising
In a state where the washing cabinet is housed in the housing, the washing cabinet is inclined so that either the front side, the rear side, or the left and right sides are lowered.

In order to solve the above problems, a dishwasher is configured to store water at the bottom of a washing cabinet, suck the water and spray it into the washing cabinet, thereby washing the dishes stored in the washing cabinet. In the dishwasher for drying the dishes by supplying hot air into the washing cabinet,
A heating unit is disposed at the bottom of the washing cabinet, a cover is provided so as to be detachable so as to cover the heating unit, a blower path is formed by the cover, and a blower unit that supplies an air flow to the blower path is provided. It is characterized by that.

  According to this dishwasher, the air flow generated by the blowing means is reliably heated by the heating means and then released into the washing cabinet. Therefore, since hot air contacts the wet dishes after washing accommodated in the washing cabinet, the drying efficiency is improved. Further, since the cover is detachable, it is easy to remove the cover and perform cleaning and maintenance of the heating means as necessary.

  In addition, it is preferable that the cover has a water passage opening. According to this configuration, the water supplied into the cleaning chamber during the cleaning operation and the rinsing operation enters the air passage through the water passage opening, and thus the water can be heated by the heating means. Therefore, the heating means can be efficiently used for heating water when washing and rinsing.

  Moreover, in such a structure, it is preferable to provide the structure for preventing the air flow by the said ventilation means from leaking out from this water flow opening inside a water flow opening. That is, at the time of drying operation, if a large amount of air flow that has not been sufficiently heated by the heating means leaks through the opening for water flow, it will contribute to the deterioration of drying efficiency. Occasionally, the structure does not leak air from the water passage opening, so that heated air can be reliably supplied into the washing cabinet.

  In addition, since small solids such as food residue adhering to the dishes are mixed in the water during the cleaning operation, such solids also flow into the air passage from the water passage opening. Therefore, it is preferable that a gap is provided between the lower edge of the cover and the bottom surface of the cleaning cabinet. Thereby, since the said solid substance which flowed in in the ventilation path flows out from the clearance gap of a cover lower end, it can prevent that a solid substance accumulates in an ventilation path and will be in an unsanitary state.

  In the dishwasher according to the fourth aspect of the present invention, the washing cabinet can be configured such that the upper surface is open and can be drawn forward from the housing having the front surface opened. According to this configuration, it becomes easier to remove the cover as necessary and clean the inside of the air passage.

  Moreover, it is preferable to set it as the structure located in the wall surface vicinity on the opposite side of the exhaust port provided in the washing | cleaning warehouse of the ventilation path formed of the said cover. According to this, the high-temperature air blown out from the blower outlet flows diagonally in the washing cabinet, and flows out of the machine from the discharge port together with the evaporated water vapor that efficiently hits the dishes stored in the washing cabinet. To do. Therefore, it is possible to quickly dry the dishes by effectively using high-temperature air.

  Further, the air outlet can be an upward opening at a position where no heating means is provided. In this configuration, the heated air stream coming through the air passage is blown out from the upward opening. For this reason, the tableware arrange | positioned in a position higher than a ventilation outlet can be dried efficiently. Further, even when an object falls from above while the heating means is heated, the heating means is not exposed at the blower outlet, so that it is possible to prevent burning or accidents of the object.

  In addition, it is preferable that the air passage has an elongated shape in the horizontal direction, and the heating means has an elongated shape along the air passage. According to this configuration, it takes a long time for the air flow to exchange heat with the heating means, and accordingly, a hot air flow can be supplied into the cleaning chamber.

  Furthermore, if the cover is made of metal, the temperature of the cover itself is increased by heating of the heating means, and there is an effect of heating the dishes located in and above the washing cabinet by the radiant heat. Therefore, more rapid drying can be achieved.

  In addition, the said ventilation means can be set as the structure arrange | positioned between the front wall of a washing | cleaning warehouse, and the front plate provided in the front surface. This configuration is particularly useful for a drawer-type dishwasher in which a washing cabinet is provided so as to be freely drawn forward from the housing.

In addition, the dishwasher includes a housing having an open front surface, guide rails mounted on both side walls of the housing, and can be drawn forward from the housing along the guide rails so that the dish can be stored on the top surface. A cleaning cabinet having an opening for taking out, an upper lid for closing the upper surface opening of the cleaning cabinet, and a tableware bowl for storing tableware disposed in parallel with the cleaning cabinet in the cleaning cabinet; In a dishwasher comprising
In a state where the washing cabinet is housed in the housing, the washing cabinet is inclined so that either the front side, the rear side, or the left and right sides are lowered.

  According to this configuration, when the washing cabinet is stored in the housing, the tableware bowl is tilted downward in the same direction as the downward tilting direction of the washing cabinet, and the dishes accommodated in the tableware bowl are inclined. For this reason, it falls to either the front, rear or left and right sides, leans against the frame around the tableware and the frame of the partition, and is in a stable state. Therefore, even if the water sprayed in the washing operation hits the tableware, the tableware is less likely to rattle, and noise caused by contact between the tableware or between the tableware and the tableware can be reduced.

  A dishwasher according to an embodiment will be described with reference to the drawings. 1 and 2 are schematic side cross-sectional views showing the overall configuration of the dishwasher according to the present embodiment. FIG. 1 shows a state in which the washing cabinet is housed in the housing, and FIG. 2 shows movement when the washing cabinet is pulled out from the housing. Indicates the state.

  A cleaning cabinet 2 having an upper surface opening 3 is disposed inside the housing 1 whose front surface is open, and a table bowl 4 for arranging tableware is installed inside the cleaning cabinet 2. A front panel 5 that also serves as a door that closes the front opening of the housing 1 is detachably screwed on the front wall 2a of the cleaning cabinet 2, and the front panel 5 and the cleaning cabinet 2 are integrally formed with the housing. The guide rails 6 installed substantially horizontally inside the both side walls of 1 and the slide rails 7 installed substantially horizontally outside the both side walls of the washing cabinet 2 can be drawn forward.

  In the upper space in the housing 1, an upper lid 8 for closing the upper surface opening 3 of the cleaning cabinet 2 is pivotally supported at one end inside the side wall of the housing 1 and supported at the side of the upper lid 8. It is supported by a pair of left and right parallel links 9 so as to be swingable. In the state where the washing cabinet 2 is housed in the housing 1, the upper lid 8 is in close contact with the upper surface of the washing cabinet 2 to close the upper opening 3 as shown in FIG. 1, and the washing cabinet 2 is moved forward from the housing 1. In the pulled out state, as shown in FIG. 2, the upper lid 8 is held in a raised state while protruding forward.

  A retractable water supply hose 10 having a water supply valve (not shown) is connected to the rear of the cleaning cabinet 2. When the water supply valve is opened, water supplied from an external water tap or the like passes through the water supply hose 10 and the cleaning cabinet 2. Poured into. A water tank 11 that is greatly depressed is communicated with the bottom of the front part of the cleaning cabinet 2, and water poured into the cleaning cabinet 2 flows into the water storage tank 11 and is stored therein. A mesh-shaped filter 11a is detachably provided on the upper portion of the water storage tank 11 for collecting food residues that flow down from the tableware when the tableware is washed. A rotatable arm 12 having a plurality of nozzles formed on the upper surface is provided at the center of the bottom of the cleaning chamber 2, and a cleaning and draining pump 13 is disposed below the bottom surface of the cleaning chamber 2. The washing and draining pump 13 includes a motor that can be driven to rotate in both directions. When the motor rotates in the forward direction, the washing and draining pump 13 functions as a washing pump, and when the motor rotates in the reverse direction, the washing and drainage pump. 13 functions as a drainage pump.

  During the cleaning operation and the rinsing operation, a water supply valve (not shown) is opened, and water is supplied into the cleaning cabinet 2 through the water supply hose 10. The water supplied into the washing cabinet 2 is collected at the bottom of the washing cabinet 2 including the water storage tank 11. In this state, when the cleaning / drainage pump 13 is driven as a cleaning pump, the water sucked from the water storage tank 11 is pumped to the arm 12 and injected into the cleaning chamber 2 from the nozzle. Thereby, water sprays on the tableware accommodated in the washing | cleaning store | warehouse | chamber 2, and dirt is removed. The food residue adhering to the tableware is collected by the filter 11a, and the water flows into the water storage tank 11 and circulates again.

  Four legs (front legs 14 and rear legs 15) for supporting the dishwasher are provided on the bottom surface of the housing 1. However, only two feet are visible in FIG. One of the features of the dishwasher of the present embodiment is that the height of the front foot portion 14 and the rear foot portion 15 is intentionally different so that the entire dishwasher is directed diagonally forward and downward. It is in. In the case 1, when the washing cabinet 2, the tableware cup 4, the upper lid 8, the guide rail 6, and the slide rail 7 are all parallel to each other, and the heights of the front foot portion 14 and the rear foot portion 15 are the same. Are arranged in a horizontal state. Therefore, when installed on a horizontal installation surface 90 as shown in FIG. 1, the washing cabinet 2, the tableware 4, the upper lid 8, the guide rail 6, and the slide rail 7 are all inclined obliquely forward and downward. Yes.

  Another feature of the dishwasher is the configuration of the guide rail 6 and the slide rail 7 for sliding the washing cabinet 2 forward. 3A and 3B are external views of the main part of the guide rail 6. FIG. 3A is a side view and FIG. 3B is a top view. 4A and 4B are external views of the main part of the slide rail 7, wherein FIG. 4A is a side view and FIG. 4B is a top view. FIG. 5 is a schematic view of a main part showing an engaged state between the guide rail 6 and the slide rail 7. Here, “side surface” and “upper surface” mean directions in a state of being attached to the dishwasher.

  As shown in FIG. 3, the guide rail 6 fixed to the housing 1 includes a roller 61 that is rotatable about a shaft 62 at the front portion of the base body 60, and is bent at the upper edge of the base body 60. An upper restricting plate portion 63 having a piece and a lower restricting plate portion 64 having a stopper 65 at the front edge are bent in the same direction at the lower edge portion.

  As shown in FIG. 4, the slide rail 7 fixed to the cleaning cabinet 2 includes a roller 71 that is rotatable around a shaft 72 at the rear portion of the base body 70, and a bent piece that hangs down on the upper edge of the base body 70. An upper regulating plate portion 73 having a lower end, and a lower regulating plate portion 74 having a stopper 75 at the rear edge are formed at the lower edge portion by bending in opposite directions. Further, the inclined portion 73a in the vicinity of the front edge portion of the upper restricting plate portion 73 has a shape bent slightly upward.

  The roller 71 of the slide rail 7 is disposed between the upper restriction plate portion 63 and the lower restriction plate portion 64 of the guide rail 6, and the roller 61 of the guide rail 6 contacts the lower surface of the upper restriction plate portion 73 of the slide rail 7. The guide rail 6 and the slide rail 7 are mounted so as to be arranged.

  When the user tries to pull out the cleaning cabinet 2 from the state in which the cleaning cabinet 2 is housed in the casing 1 (see L0 in FIG. 2), the cleaning cabinet 2 starts with the inclination of the casing 1 as described above. Slide in the same direction, that is, diagonally forward and downward. At this time, the roller 71 of the slide rail 7 rolls in contact with the lower surface of the upper restriction plate portion 63 of the guide rail 6, and the roller 61 of the guide rail 6 contacts the lower surface of the upper restriction plate portion 73 of the slide rail 7. Rotate.

  When the cleaning chamber 2 is pulled out a little and the inclined portion 73a of the upper regulating plate portion 73 of the slide rail 7 is caught on the roller 61 of the guide rail 6 (see FIG. 5), the roller 71 of the slide rail 7 and the guide rail on the rear side. Since the upward movement is restricted by the contact with the upper restricting plate portion 63, the slide rail 7 is inclined so as to be directed obliquely upward, and the upward inclination is gradually increased as the cleaning cabinet 2 is pulled out. growing. That is, as shown in FIG. 2, as the cleaning cabinet 2 is pulled out from the inside of the housing 1, the pulling direction gradually becomes upward, so that it is substantially parallel (that is, horizontal) to the installation surface 90 during the pulling ( (See L1 in FIG. 2). Further, when it is further pulled out, it is inclined upward (see L2 in FIG. 2). The washing cabinet 2 can be pulled out to a position where the stopper 75 of the slide rail 7 contacts the stopper 65 of the guide rail 6.

  As described above, in this dishwasher, when the washing cabinet 2 starts to be pulled out from the housing 1, it starts to move diagonally forward and downward, so that some components of gravity acting on the washing cabinet 2 are moved by the washing cabinet. Acts on direction. Therefore, the user can start pulling out the washing cabinet 2 without applying a great force. Once the slide movement is started, the inertial force works, and the washing cabinet 2 can be pulled out without difficulty even if the direction of the washing cabinet 2 is shifted from the horizontal direction to the upper oblique direction.

  Further, as shown in FIG. 2, the bottom surface of the bottom cover 2 f provided below the cleaning chamber 2 so as to cover the cleaning / drainage pump 13 is formed so that the cleaning chamber 2 is inclined upward with the amount of withdrawal. It is possible to avoid contact with the front lower edge 1b. When a large number of dishes are stored in the tableware bowl 4 in the washing cabinet 2, the weight increases considerably, so that the front part of the washing cabinet 2 is lowered particularly when it is pulled forward. Even in this case, the front portion is not inclined downward as compared with the horizontal state, and the lower surface of the bottom cover 2f can be prevented from coming into contact with the front lower edge end portion 1b of the housing 1.

  Furthermore, in this dishwasher, in order to avoid such contact more reliably, the shape of the bottom surface of the bottom cover 2f is not on the same plane as shown in FIG. 1, but below the washing and draining pump 13 on the rear side. Then, it is lowered so that the pump 13 can be accommodated, and is raised in front of it. As a result, the distance d1 between the bottom cover 2f and the bottom plate 1a of the housing 1 is larger than the same distance d2 on the rear side, and in particular, the cleaning cabinet 2 is pulled out from the housing 1 while tilting forward. When starting, contact between the lower surface of the bottom cover 2f and the front lower edge 1b of the housing 1 is avoided. However, lowering the bottom cover 2f only below the cleaning / drainage pump 13 in this way is not inclining forward when the cleaning cabinet 2 starts to be pulled out, even if it is almost horizontal, during the pulling operation. The same effect can be obtained if it faces upward. Further, raising the bottom surface of the bottom cover 2f at a portion other than the cleaning / drainage pump 13 simply increases the margin of the gap between the bottom surface of the bottom cover 2f and the front lower edge 1b of the housing 1. Thus, it is also effective in reducing the risk of contact due to variations in the dimensions of each member, assembly, or play (play).

  Moreover, in this dishwasher, since the tableware bowl 4 also inclines in the state in which the washing machine 2 is stored in the housing 1, the tableware bowl (such as a dish) accommodated in the tableware bowl 4 is horizontal. Compared with the case where it is arranged, it is kept in a state of being inclined more greatly. Therefore, the noise generated when the tableware or the tableware and the tableware come into contact with each other even when the water sprayed from the nozzles of the arm 12 during the washing operation or the overrunning operation is struck. Can be reduced.

  Furthermore, in this dishwasher, since the water storage tank 11 is provided in front of the washing cabinet 2 inclined forward, the water stored in the washing cabinet 2 is easily collected in the water storage tank 11. Therefore, the amount of water stored in the washing cabinet 2 can be relatively collected at least in the water storage tank 11 and circulated for use. Moreover, since the water which fell on the tableware flows smoothly to the water storage tank 11 without staying, the food residue mixed in this water can be collected more efficiently by the filter 11a. Further, since the water remaining in the washing cabinet 2 is reliably and quickly collected in the water storage tank 11 even during drainage, the drainage time can be shortened without accumulating in other places in the washing cabinet 2.

  Next, the dishwasher which is one Example of this invention is demonstrated. In addition, the same code | symbol is attached | subjected to the part which is the same as that of the said Example, or the description is abbreviate | omitted unless there is a description in particular. FIG. 6 is a schematic side sectional view showing the overall configuration of the dishwasher according to the present embodiment, and FIG. 7 is a top view of the washing cabinet of the dishwasher according to the present embodiment.

  In the dishwasher of this embodiment, air blowing means for supplying high-temperature air into the washing cabinet 2 during the drying operation is disposed between the front wall 2a of the washing cabinet 2 and the front panel 5. That is, a vertical air passage 20 is provided in which an air inlet 21 that is an air inlet opens toward the inside of the housing 1, and an air outlet 22 that is an air outlet opens below the front wall 2 a of the cleaning cabinet 2. A fan 23 that is rotationally driven by a blower motor 24 is provided at a position immediately after entering the air inlet 21. In addition, a damper 25 that closes by its own weight is provided in the vertical air passage 20. An exhaust port 29 that is an exhaust outlet opens at the upper part of the front panel 5 spaced from the blower port 22 and communicates with an exhaust outlet 27 that is an exhaust inlet through an exhaust path 26. A damper 28 is provided at the exhaust outlet 27 to prevent the internal noise during the cleaning operation and the rinsing operation from leaking to the outside. The vertical air passage 20 and the exhaust passage 26 are connected by an auxiliary exhaust passage 23 so that water vapor flowing back through the vertical air passage 20 during the cleaning operation or the rinsing operation is released to the exhaust passage 26.

  A sheathed heater 16 having an elongated shape extending in the front-rear direction is attached to the cleaning cabinet 2 from the front side immediately below the outlet of the blower port 22, and a metal air passage cover 30 is provided detachably so as to cover it. It has been. Since the sheathed heater 16 is disposed on the first bottom surface 2d that is one step lower than the others in the bottom surface of the cleaning chamber 2 except for the water storage tank 11, at least the amount of water supplied into the cleaning chamber 2 is at least the sheathed heater. 16 is surely immersed in water. The air path cover 30 has a tubular shape having a bottom wall 31 at a location corresponding to the non-heated portion of the sheathed heater 16 in the vicinity of the air blowing port 22, and its end face is connected to the air blowing port 22 with almost no gap. Further, the tip of the tubular portion of the air passage cover 30 does not have a bottom surface, but has only both side surfaces and an upper surface. Further, the end of the air path cover 30 opposite to the air blowing port 22 has an acute-angled folded piece 30a, which is in close proximity to or in contact with the rib 2e protruding from the bottom surface of the cleaning cabinet 2, thereby leaking airflow. Blocking.

  A gap 34 having a predetermined height is formed on the side surface of the air passage cover 30 with the first bottom surface 2d of the cleaning cabinet 2, and a plurality of water passage holes 32 wide in the width direction are formed on the upper surface. Have. The water passage hole 32 is provided with a louver 33 extending in a tongue shape on the inside thereof, and the air flow flowing from the air blowing port 22 side is prevented from entering the water passage hole 32. The air passage cover 30 is formed with a notch on the side opposite to the left side wall 2b facing upward and close to the front end of the air passage formed by the folded piece 30a and the rib 2e on the washing cabinet 2 side, This is the hot air outlet 35 that is the outlet of the air flow. As a result, a transverse air passage 36 is formed between the air passage cover 30 and the first bottom surface 2d of the cleaning cabinet 2 with the air outlet 22 as an inlet and the hot air outlet 35 as an outlet.

  During the cleaning operation or the rinsing operation, a water supply valve (not shown) is opened, and water is supplied into the cleaning cabinet 2 through the water supply hose 10. In addition, a heating current is supplied to the sheathed heater 16. The water supplied into the washing chamber 2 first accumulates in the lowest water storage tank 11, and when the water storage tank 11 becomes full, it accumulates on the next lower first bottom surface 2d. At this time, water flows into the horizontal air passage 36 from the warm air port 35, the water passage hole 32, and the gap 34, and the sheathed heater 16 is immersed in water. Therefore, the water is warmed by heat exchange with the sheathed heater 16.

  When the washing and draining pump 13 operates as a washing pump, the hot water sucked from the water storage tank 11 is pumped to the arm 12 and injected into the washing chamber 2 from the nozzle. Thereby, water sprays on the tableware accommodated in the washing | cleaning store | warehouse | chamber 2, and dirt is removed. The food residue adhering to the tableware is collected by a mesh-like filter 11a detachably provided on the upper surface of the water storage tank 11, and the water flows into the water storage tank 11 and circulates again. Further, even if such a solid material enters the horizontal air passage 36 from the water passage hole 32, it smoothly flows out from the lower gap 34, so that it can be prevented from accumulating in the horizontal air passage 36.

  Next, the operation during the drying operation will be described. During the drying operation, the blower motor 24 is driven to rotate the fan 23 in a predetermined direction. Then, the air sucked from the air inlet 21 is pumped to the vertical air passage 20, and the damper 25 is opened by this pressure, and the air flow is discharged from the air outlet 22. This air flow flows into the horizontal air passage 36 and becomes hot air by heat exchange with the sheathed heater 16 while passing through the horizontal air passage 36. Since warm air has a lower specific gravity than cold air, even if there is a gap 34 at the lower edge of the air passage cover 30, the warm air does not escape from here. Further, although the water passage hole 32 is opened on the upper surface, since the water passage hole 32 is shielded by the louver 33 when viewed from the upstream side of the air flow, the leakage of warm air from the water passage hole 32 can be prevented. . Therefore, heat is efficiently exchanged in the horizontal air passage 36, and sufficiently heated air is blown out from the hot air outlet 35 at the end into the washing chamber 2.

  The warm air port 35 is located at a diagonal position with respect to the exhaust outlet 27 and is also separated in the height direction. Therefore, as shown in FIG. 7, the air blown out from the warm air port 35 crosses the inside of the washing cabinet 2 obliquely, contacts the tableware, and vaporizes the moisture attached to the tableware. For this reason, it can be efficiently dried, that is, if it is the same heating power, quickly, and if it is the same drying operation time, it can be sufficiently dried even if the heating power of the sheathed heater 16 is reduced. Further, since the air passage cover 30 is made of metal, the air passage cover 30 itself receives heat from the sheathed heater 16 and becomes very hot, and the upper tableware bowl (not shown in FIG. 6 but shown in FIG. 1 as shown in FIG. 1) Radiant heat is released to the tableware housed in 4). Therefore, the drying efficiency is enhanced not only by the high-temperature air flow but also by this radiant heat.

  In this way, in the dishwasher according to the present embodiment, the air flow from the air outlet 22 intensively passes through the horizontal air passage 36 formed by the air passage cover 30, and at that time, efficiently with the sheathed heater 16. Heat exchange is performed and a high-temperature air stream is discharged from the warm air port 35. The drying efficiency of the dishes is improved by the high-temperature air flow and the radiant heat of the air path cover 30. Further, since the user can easily remove the air passage cover 30 by putting his / her hand through the upper surface opening 3, the air passage cover 30 itself and its lower side can be easily cleaned.

  Note that the above embodiment is merely an example, and it is obvious that changes and modifications can be made as appropriate within the scope of the present invention.
