Detailed Implementation

[0024] (Insights, etc., that form the basis of this disclosure)

[0025] When the inventors conceived of this disclosure, there existed a technology comprising: a dishwashing and drying machine including: a main body having a washing tank inside for receiving the items to be washed; an air supply mechanism for supplying air from inside the washing tank to the outside of the main body; and a cooling fan for mixing the air from inside the washing tank and the air supplied by the cooling fan inside the main body and discharging it to the outside of the main body. Thus, in the dishwashing and drying machine, the air from inside the washing tank can be discharged to the outside of the main body with reduced humidity and temperature, preventing the discharge of hot and humid air to the surrounding area of ​​the dishwashing and drying machine.

[0026] However, the inventors have discovered the following problem, which is a concern: when the gas inside the cleaning tank and the air delivered by the cooling fan are mixed inside the main body, the gas and the air delivered by the cooling fan collide inside the main body, and the flow rate of the gas discharged to the outside of the main body decreases. In order to solve this problem, the subject of this disclosure is formed.

[0027] Therefore, this disclosure provides a dishwashing and drying machine that can suppress the reduction of drying efficiency of the washed items.

[0028] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, there are instances where unnecessary details are omitted. For example, detailed descriptions of already well-known matters or repetitive descriptions of substantially the same structures may be omitted. This is to avoid making the following description unnecessarily lengthy and to facilitate understanding by those skilled in the art.

[0029] Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure, and are not intended to limit the subject matter of the claims by means of the drawings and the following description.

[0030] (Implementation Method 1)

[0031] The following uses Figures 1 to 7 Description of Embodiment 1. In the figures, reference numeral FR indicates the front of the dishwashing and drying machine 1 in its normally used position, reference numeral UP indicates the top of the dishwashing and drying machine 1, and reference numeral LH indicates the left side of the dishwashing and drying machine 1. In the following description, all directions refer to the directions along the dishwashing and drying machine 1 described above. In the dishwashing and drying machine 1 in its installed position, the up-down direction aligns with the vertical direction, and the front-back and left-right directions align with the horizontal direction.

[0032] [1-1. Structure]

[0033] [1-1-1. Structure of a dishwashing and drying machine]

[0034] Figure 1 This is a perspective view showing the dishwashing and drying machine 1 in Embodiment 1. Figure 1 The image shows the dishwashing and drying machine 1 with door 16 open. Figure 1 In the diagram, arrow A1 indicates the flow of gas discharged from the interior of the self-cleaning tank 14.

[0035] like Figure 1 As shown, the dishwashing and drying machine 1 is a built-in dishwashing machine assembled in a complete kitchen.

[0036] The dishwashing and drying machine 1 has a main body 10. The main body 10 has a housing 12 disposed on the upper part of the main body and a base frame 20 disposed on the lower part of the main body 10.

[0037] Figure 2 yes Figure 1 A sectional view at plane II. Plane II is a plane orthogonal to the left-right direction and intersects the air duct 70. Figure 2 In the image, for ease of illustration, the dishwashing and drying machine 1 is shown with door 16 closed. Figure 2For ease of explanation, this indicates the state in which the dishwashing and drying machine 1 is installed with the surface material 90 and the kick plate 92 configured relative to the set state.

[0038] like Figure 1 As shown, the housing 12 is formed as a box with an open front surface. A front surface opening 11 is provided on the front surface of the housing 12, allowing communication between the inside and outside of the housing 12. A door 16 is installed on the front surface of the housing 12 in a manner that allows it to be opened and closed, covering the front surface opening 11.

[0039] like Figure 2 As shown, when the dishwashing and drying machine 1 is assembled into the overall kitchen, a surface material 90 that functions as a decorative panel is installed on the front surface of the door 16.

[0040] like Figure 1 As shown, a cleaning tank 14 for holding the item D to be cleaned is provided inside the housing 12. A basket 18 for holding the item D to be cleaned is arranged inside the cleaning tank 14.

[0041] A cleaning nozzle is provided at the bottom of the cleaning tank 14 to blow cleaning water into the cleaning tank 14.

[0042] The housing 12 is mounted on and supported by the base frame 20. The base frame 20 is formed as a box with an open top surface. Figure 2 As shown, the upper part of the base frame 20 is entirely covered by the bottom surface 12A of the housing 12 placed on the base frame 20. The bottom surface 12A forms the bottom surface of the cleaning tank 14.

[0043] The housing 12 is configured such that its front end protrudes forward beyond the front end of the base frame 20. Therefore, the door 16 and the faceplate 90 are positioned further forward than the front end of the base frame 20.

[0044] like Figure 2 As shown, there is a situation where the dishwashing and drying machine 1 is embedded in an integrated kitchen, and a kickboard 92, which serves as a decorative panel, is provided in front of the base frame 20. The kickboard 92 is provided, for example, upright from the mounting surface G of the main body 10. The kickboard 92 is positioned at a position that is separated from the front end of the base frame 20 by a predetermined distance in the front-to-back direction.

[0045] Figure 3 This is a block diagram of the dishwashing and drying machine 1.

[0046] like Figure 3 As shown, the dishwashing and drying machine 1 includes a control device 30 for controlling various parts of the dishwashing and drying machine 1. The control device 30 includes a processor 100 and a memory 110, and functions as a control unit for controlling various parts of the dishwashing and drying machine 1.

[0047] The processor 100 is a CPU (Central Processing Unit), MPC (Micro Processing Unit), or other processors. The processor 100 functions as an operation control unit 101 by reading and executing the control program 111 stored in the memory 110.

[0048] The memory 110 functions as a storage unit for programs and data. The memory 110 stores the control program 111 and the data processed by the processor 100. The memory 110 has non-volatile storage areas. Alternatively, the memory 110 may also have volatile storage areas, constituting the working area of ​​the processor 100.

[0049] The dishwashing and drying machine 1 includes a circulation pump 31, a drain pump 32, a water supply pump 33, a washing water heater 34, a blower fan 36, a drying heater 38, a cooling fan 60, and a temperature sensor 39. The control device 30 is connected to the circulation pump 31, drain pump 32, water supply pump 33, washing water heater 34, blower fan 36, drying heater 38, cooling fan 60, and temperature sensor 39. The control device 30 has interfaces for connecting the aforementioned equipment and circuits. Furthermore, the equipment and circuits connected to the control device 30 are not limited to these; other equipment and circuits may also be connected.

[0050] The circulating pump 31 is a pump device that is driven by the control device 30 to circulate the cleaning water supplied to the cleaning tank 14 through the circulation path and spray the cleaning water from the cleaning nozzle.

[0051] The drain pump 32 is a pump device that is driven by the control device 30 to discharge cleaning water from the cleaning tank 14.

[0052] The water supply pump 33 is a pumping device that is driven under the control of the control device 30 and sprays cleaning water from the cleaning nozzle. The dishwashing and drying machine 1 has a water storage tank for storing cleaning water supplied from outside the main body 10. The water supply pump 33 causes the cleaning water supplied from the water storage tank to be sprayed from the cleaning nozzle.

[0053] The cleaning water heater 34 heats up under the control of the control device 30 to heat the cleaning water sprayed from the self-cleaning nozzle 8.

[0054] The blower fan 36 is a blower device that rotates under the control of the control device 30. The blower fan 36 delivers outside air as a drying airflow into the washing tank 14, so that the items D to be washed placed in the basket 18 are dried.

[0055] The dryer heater 38 generates heat according to the control device 30, thereby heating the air delivered by the blower fan 36.

[0056] The cooling fan 60 is an air supply device that rotates under the control of the control device 30. The cooling fan 60 delivers air to cool the gas discharged from the self-cleaning tank 14 at a higher speed or with a greater air volume than the air supply fan 36.

[0057] Temperature sensor 39 is a sensor that is driven by control device 30 to measure the temperature of the exterior of main body 10, i.e., the installation space of dishwashing and drying machine 1. Temperature sensor 39 sends the measured temperature as data to control device 30. Furthermore, temperature sensor 39 may also be configured to measure the temperature of the washing water. Alternatively, for example, dishwashing and drying machine 1 may also have a separate sensor for measuring the temperature of the washing water, separate from temperature sensor 39.

[0058] The operation control unit 101 controls the operation of the dishwashing and drying machine 1. In this embodiment, the operation of the dishwashing and drying machine 1 is related to the cleaning of the items D stored inside the cleaning tank 14. This operation can be performed continuously in the order of cleaning, rinsing, and drying, or it can be performed only in any order, or it can be performed in any order of any two or more orders.

[0059] [1-1-2. Structures related to the exhaust of dry air]

[0060] like Figure 1 As shown, the housing 12 is provided with an exhaust opening 21. The exhaust opening 21 is a through hole that connects the interior of the cleaning tank 14 and the exterior of the housing 12. In this embodiment, the exhaust opening 21 is provided on one side of the housing 12.

[0061] The housing 12 is provided with an exhaust pipe 22. The exhaust pipe 22 is a tubular or pipe-shaped component. One end of the exhaust pipe 22 is connected to the exhaust opening 21. Thus, the gas inside the cleaning tank 14 flows to the exhaust pipe 22. The gas inside the cleaning tank 14 is sent out through the exhaust opening 21 by a blower fan 36.

[0062] The gas inside the cleaning tank 14 is, for example, air or water vapor from the cleaning water.

[0063] The exhaust pipe 22 extends downward from the exhaust opening 21. The other end of the exhaust pipe 22 is connected to the interior of the base frame 20.

[0064] Figure 4 This is a three-dimensional view obtained by observing the base frame 20 from the rear. Figure 4In the diagram, arrow A1 indicates the flow of gas discharged from the interior of the self-cleaning tank 14, and arrow A2 indicates the flow of air delivered by the cooling fan 60. Figure 4 In the diagram, a single-dot dashed line is used to represent the extension line L1 extending along the length direction of the side surface 50A, and the extension line L2 extending along the length direction of the air guide plate 72 on the plane of the air guide plate 72.

[0065] like Figure 4 As shown, the base frame 20 is formed as a box with an internal space. Alternatively, at least one of the following can be housed inside the base frame 20: a circulation pump 31, a drain pump 32, a water supply pump 33, a cleaning water heater 34, a blower fan 36, and a drying heater 38.

[0066] The base frame 20 includes a front surface plate 40 forming the front surface, side panels 42 and 44 forming the left and right sides, a rear surface plate 46 forming the rear surface, and a bottom panel 48 forming the bottom surface.

[0067] When viewed from above, the bottom panel 48 forms a roughly rectangular plate, becoming the bottom surface of the main body 10. The front panel 40, side panels 42 and 44, and rear panel 46 rise from each side of the bottom panel 48.

[0068] The base frame 20 has an internal space S surrounded by a front surface plate 40, side panels 42 and 44, a rear surface plate 46, a bottom panel 48 forming the bottom surface, and the bottom surface of the housing 12. Alternatively, the internal space S may house, for example, a circulation pump 31, a drain pump 32, a water supply pump 33, a cleaning water heater 34, a control device 30, a water storage tank, etc.

[0069] Figure 5 This is a three-dimensional view obtained by observing the base frame 20 from the front. Figure 5 In the diagram, arrow A1 represents the flow of gas discharged from the interior of the self-cleaning tank 14, arrow A2 represents the flow of air supplied by the cooling fan 60, and arrow A3 represents the mixture of gas discharged from the interior of the self-cleaning tank 14 and air supplied by the cooling fan 60.

[0070] like Figure 5 As shown, an exhaust port 51 is provided on the front surface panel 40. The exhaust port 51 is a through hole extending through the upper end of the front surface panel 40 along the thickness direction of the front surface panel 40. In this embodiment, the exhaust port 51 is located near the right end of the front surface panel 40.

[0071] like Figure 4 As shown, an exhaust pipe 50 is provided in the internal space S of the base frame 20. The exhaust pipe 50 is a component formed in the shape of a tube or conduit. One end of the exhaust pipe 50 is connected to an exhaust port 51.

[0072] The other end of the exhaust pipe 22 is connected to the exhaust port pipe 50. The gas inside the washing tank 14 is sent out by the blower fan 36 through the exhaust opening 21, the exhaust pipe 22, and the exhaust port pipe 50, and is discharged to the outside of the main body 10 through the exhaust port 51. Thus, in the dishwashing and drying machine 1, the exhaust opening 21, the exhaust pipe 22, the exhaust port pipe 50, and the exhaust port 51 form an exhaust flow path for the gas discharged from the washing tank 14.

[0073] The exhaust pipe 50 is shaped to guide the gas flowing in from the exhaust pipe 22 toward the front of the main body 10 via the exhaust port 51.

[0074] The exhaust duct 50 has a side panel 50A located on the left. The side panel 50A is configured to be opposite to the side panel 42 and tilted to the left when viewed from above as it moves from rear to front. As a result, exhaust gas flowing from the exhaust duct 22 into the exhaust duct 50 is guided along the side panel 50A and directed to the left of the main body 10 when viewed from above.

[0075] In addition, the exhaust pipe 50 can also be shaped to guide the gas flowing from the exhaust pipe 22 to the left, right, or above and below the main body 10 via the exhaust port 51.

[0076] Alternatively, in the dishwashing and drying machine 1, a pump device such as a fan can be provided at any position in the exhaust flow path to send the gas inside the washing tank 14 to the outside of the main body 10.

[0077] like Figure 5 As shown, an air outlet 53 is provided on the front panel 40. The air outlet 53 is a through hole extending along the thickness direction of the front panel 40. The air outlet 53 is positioned approximately at the same location as the exhaust port 51 in the vertical direction. In this embodiment, the air outlet 53 is positioned near the left end of the front panel 40. That is, the exhaust port 51 and the air outlet 53 are positioned separately from each other in the horizontal direction.

[0078] Figure 6 It will be with Figure 4 The VI represents the scope shown in the diagram in an enlarged manner.

[0079] like Figure 4 , Figure 6As shown, a cooling fan 60 is provided in the internal space S. The cooling fan 60 is disposed on the front panel 40 on the surface opposite to the internal space S, at least partially overlapping with or adjacent to the air outlet 53. The cooling fan 60 in this embodiment is a blower fan. The cooling fan 60 is provided with an air intake opening 61 for drawing in air when the cooling fan 60 is driven and an air outlet opening 63 for blowing out the drawn-in air.

[0080] In addition, the cooling fan 60 is not limited to a blower fan, but can also use various air supply devices such as axial fans and centrifugal fans.

[0081] The cooling fan 60 is fixed to the front surface panel 40 by means of a plurality of fixing parts 41 integrally formed with the front surface panel 40. In this embodiment, the fixing parts 41 protrude from the surface of the front surface panel 40 opposite to the internal space S toward the internal space S, and the front ends are formed into claw shapes. The cooling fan 60 is fixed to the front surface panel 40 at approximately the same height as the air outlet 53 in the vertical direction by engaging with the front parts of the fixing parts 41 respectively.

[0082] Therefore, in the dishwashing and drying machine 1, the increase in the number of parts can be suppressed, and the cooling fan 60 can be easily positioned to deliver air through the air outlet 53.

[0083] When the cooling fan 60 is mounted on the front panel 40 by the fixing part 41, the air intake opening 61 opens in the internal space S, and the air outlet opening 63 opens at least partially overlapping with the air outlet 53, or at a position adjacent to the air outlet 53. The air outlet opening 63 is configured to face to the right.

[0084] Figure 7 It will be with Figure 5 The range represented by VII is shown in the enlarged diagram.

[0085] like Figure 6 As shown, an air duct 70 is provided on the surface of the front panel 40 opposite to the internal space S. The air duct 70 is formed into a pipe shape integrally disposed with the front panel 40.

[0086] like Figure 6 , Figure 7 As shown, one end of the air duct 70 covers the air outlet 63 of the cooling fan 60. The other end of the air duct 70 is connected to the air outlet 53. Thus, the air duct 70 connects the air outlet 63 and the air outlet 53. The end of the cooling fan 60, which has the air outlet 63, is exposed outside the base frame 20 via the air outlet 53.

[0087] The air duct 70 includes a plate-shaped air guide plate portion 72 that faces both the air outlet 63 and the air outlet 53. The end of the air guide plate portion 72 adjacent to the air outlet 63 along the front-rear direction is disposed separately from the surface of the front surface plate 40 that faces the internal space S. The air guide plate portion 72 is disposed at an angle so that it approaches the surface of the front surface plate 40 that faces the internal space S as it moves from the air outlet 63 toward the air outlet 53.

[0088] Therefore, when the cooling fan 60 is driven, the air blown out from the air outlet 63 is guided by the air guide plate 72, and thus the air is blown out of the body 10 to the right from the air outlet 53.

[0089] like Figure 4 As shown by arrow A2, in this embodiment, the air guide plate 72 is arranged at an angle relative to the surface of the front surface plate 40 opposite to the internal space S, such that the air blown out from the air outlet 53 is directed towards the gas blown out from the exhaust port 51 outside the main body 10.

[0090] In this way, the cooling air delivered by the cooling fan 60 is guided by the air duct 70 which is integrally provided with the front surface panel 40. Therefore, in the dishwashing and drying machine 1, the increase in the number of parts can be suppressed, and the direction of the cooling air can be easily controlled.

[0091] The air duct 70 forms a cooling airflow path for the cooling air delivered by the cooling fan 60.

[0092] In the front panel 40, a plurality of air rectifiers 74 are provided inside the air outlet 53. The air rectifiers 74 are, for example, formed in the shape of louvers extending from the air outlet 53 into the interior of the air duct 70, and rectify the air blown out from the air outlet 53. In this embodiment, the various air rectifiers 74 are arranged in a planar and vertically intersecting manner. Alternatively, the air rectifiers 74 may be omitted.

[0093] [1-2. Actions]

[0094] Regarding the dishwashing and drying machine 1 configured as described above, its operation is explained below.

[0095] [1-2-1. Operations related to the cleaning of the items being cleaned]

[0096] like Figure 3 As shown, the dishwashing and drying machine 1 operates according to the control of the control device 30, performing the washing, rinsing and drying processes.

[0097] In the cleaning and rinsing processes, the control device 30 drives the cleaning water heater 34 to heat the cleaning water. The control device 30 also drives the water supply pump 33, causing the cleaning water supplied from the water tank to be sprayed from the cleaning nozzles to clean the object D. Furthermore, the control device 30 drives the circulation pump 31 to circulate the cleaning water supplied to the cleaning tank 14 through a circulation path, and sprays the cleaning water from the cleaning nozzles to clean the object D and perform rinsing. Finally, the control device 30 drives the drain pump 32 to discharge the cleaning water from the cleaning tank 14.

[0098] During the drying process, the control device 30 drives the air supply fan 36, the drying heater 38, and the cooling fan 60.

[0099] When the blower fan 36 is driven to rotate by the control device 30, it draws in external air from the main body 10 into the interior of the washing tank 14. The external air drawn into the interior of the main body 10 is heated by the drying heater 38 midway through its flow path toward the washing tank 14, thus becoming drying air. The drying air is then expelled into the washing tank 14, drying the items D placed in the basket 18.

[0100] The drying air supplied to the interior of the cleaning tank 14 causes at least a portion of the cleaning water remaining inside the cleaning tank 14 to become water vapor and hot air. This water vapor and hot air mixes with the air flowing as the drying air and is discharged from the cleaning tank 14 through the exhaust path, exiting from the exhaust port 51 toward the front of the main body 10 and outwards.

[0101] Here, as Figure 2 As shown, there is a situation where the dishwashing and drying machine 1 is embedded in an integrated kitchen, with a panel 90 installed on the door 16 and a base plate 92 serving as a decorative panel positioned in front of the base frame 20. The base plate 92 is positioned at a distance that is separated from the front panel 40 of the base frame 20 by a predetermined distance in the front-to-back direction.

[0102] Therefore, the gas blown out from the exhaust port 51 is directed toward the surface material 90, the kick plate 92, and the mounting surface G located on the front side of the front surface panel 40.

[0103] like Figure 4 As shown, in the dishwashing and drying machine 1 of this embodiment, a cooling fan 60 is used to send out cooling air to cool the gas blown out of the exhaust port 51.

[0104] The cooling fan 60 draws in air from the internal space S and delivers it out as cooling air. A cleaning tank 14 is disposed above the internal space S. Therefore, during the cleaning, rinsing, and drying processes, the internal space S is heated at a lower temperature than the interior of the cleaning tank 14 due to the heating of the cleaning water and drying air. Consequently, the cooling fan 60 delivers cooling air at a temperature lower than the interior of the cleaning tank but higher than the outside air of the main body 10.

[0105] Therefore, in the dishwashing and drying machine 1, the temperature of the gas blown out from the exhaust port 51 can be prevented from dropping sharply, and the gas blown out from the exhaust port 51 can be cooled. Thus, in the dishwashing and drying machine 1, the exhaust temperature and humidity can be reduced, and the exhaust temperature can be prevented from dropping below a predetermined temperature relative to the outside air of the main body 10, thus preventing condensation from forming on the outside of the main body 10. Furthermore, in the dishwashing and drying machine 1, the user is prevented from coming into contact with condensed, high-temperature, and humid exhaust gas.

[0106] In the dishwashing and drying machine 1 of this embodiment, cooling air delivered by the cooling fan 60 is blown out from the air outlet 53, which is positioned separately from the exhaust port 51. As a result, the gas discharged from the washing tank 14 is cooled by colliding with and mixing with the cooling air outside the main body 10. Therefore, it is possible to prevent the cooling air from entering the exhaust port 51 and hindering the discharge of the gas discharged from the washing tank 14 from the exhaust port 51 inside the main body 10. Thus, in the dishwashing and drying machine 1, the reduction in drying efficiency of the washed items D can be suppressed.

[0107] The cooling fan 60 delivers cooling air at a higher speed or with a greater airflow than the supply fan 36. In addition, the cooling airflow path is shorter than the exhaust airflow path.

[0108] Therefore, the cooling air outside the main body 10 collides with the gas discharged from the self-cleaning tank 14.

[0109] like Figure 4 As shown, an extension line L1 extending along the length direction of the side surface 50A and an extension line L2 extending along the length direction of the air guide plate portion 72 are intersected. The angle α formed by the extension lines L1 and L2 is 60 degrees or more and 180 degrees or less when viewed from above, and more preferably an obtuse angle.

[0110] As a result, the exhaust air guided by the side 50A and the cooling air guided by the air guide plate 72 collide and mix at a position that does not reach the kick plate 92.

[0111] In this way, the exhaust gas from the dishwashing and drying machine 1 is cooled by mixing with cooling air, such as... Figure 5 As shown by arrow A3, the flow changes its course laterally from the front side of the main body 10 to the right side.

[0112] Therefore, in the dishwashing and drying machine 1, the flow of gas blown from the exhaust port 51 toward the front of the main body 10 can be suppressed. Therefore, in the dishwashing and drying machine 1, the condensation adhering to the surface material 90, the kick plate 92, the installation surface G located on the front side of the front surface plate 40, etc., can be suppressed.

[0113] Furthermore, for cooling air, the shape and length of the cooling fan's air duct 70, or the tilt angle of the air guide plate 72, can be changed to alter the outlet angle of the cooling air blowing from the outlet opening 63. For example, by making the length of the duct 70 greater than... Figure 4 When the length dimension shown is long, the angle α becomes larger, making the length dimension of the pipe 70 greater than... Figure 4 When the length dimension is short, the angle α becomes smaller.

[0114] [1-3. Effects, etc.]

[0115] As described above, in this embodiment, the dishwashing and drying machine 1 includes a main body 10 with a washing tank 14 for storing dishwashings. The main body 10 is provided with: an exhaust port 51 that discharges gas from the washing tank 14 to the outside of the main body 10; a cooling fan 60 that cools the gas discharged from the exhaust port 51; and an air outlet 53 that blows cooling air from the cooling fan 60 to the outside of the main body 10. The gas discharged from the exhaust port 51 and the cooling air blown from the air outlet 53 are mixed by colliding with the outside of the main body 10.

[0116] Accordingly, in the dishwashing and drying machine 1, it is possible to prevent the cooling air from entering the exhaust port 51 and obstructing the exhaust of gas discharged from the washing tank 14 from the exhaust port 51 inside the main body 10. Thus, in the dishwashing and drying machine 1, it is possible to suppress the reduction in the drying efficiency of the washed items D.

[0117] As in this embodiment, the exhaust port 51 and the air outlet 53 can also be located in different positions.

[0118] Accordingly, in the dishwashing and drying machine 1, it is possible to prevent the cooling air from entering the exhaust port 51 and obstructing the exhaust of gas discharged from the washing tank 14 from the exhaust port 51 inside the main body 10. Thus, in the dishwashing and drying machine 1, it is possible to suppress the reduction in the drying efficiency of the washed items D.

[0119] As in this embodiment, the exhaust port 51 and the air outlet 53 can also be arranged on the same surface of the main body 10.

[0120] Accordingly, in the dishwashing and drying machine 1, the flow of gas blown from the exhaust port 51 toward the front of the main body 10 can be suppressed. Therefore, in the dishwashing and drying machine 1, the condensation adhering to the surface material 90, the kick plate 92, the installation surface G located on the front side of the front surface plate 40, etc., can be suppressed.

[0121] As in this embodiment, the cooling fan 60 can also draw in air from inside the main body 10 and blow it out from the air outlet 53.

[0122] Accordingly, in the dishwashing and drying machine 1, it is possible to prevent a sharp drop in the temperature of the gas blown out of the exhaust port 51 and to cool the gas blown out of the exhaust port 51. Therefore, in the dishwashing and drying machine 1, it is possible to prevent condensation from forming on the outside of the main body 10.

[0123] As in this embodiment, the main body 10 may have an internal space S separated from the cleaning tank 14, and the cooling fan 60 may draw air from the internal space S and blow it out from the air outlet 53.

[0124] Accordingly, in the dishwashing and drying machine 1, the exhaust temperature and humidity can be reduced, and the situation where the exhaust temperature drops below a predetermined temperature relative to the outside air of the main body 10 can be suppressed, thus preventing condensation from forming on the outside of the main body 10. Furthermore, in the dishwashing and drying machine 1, the situation where the user comes into contact with condensed, high-temperature, and humid exhaust can be prevented.

[0125] As in this embodiment, the air outlet 53 can also be integrally set with the main body 10.

[0126] Accordingly, the cooling air delivered by the cooling fan 60 is guided by the air duct 70 integrally provided with the front surface panel 40. Therefore, in the dishwashing and drying machine 1, the increase in the number of parts can be suppressed, and the direction of the cooling air can be easily controlled.

[0127] As in this embodiment, the fixing part 41 for fixing the cooling fan 60 can also be integrally provided on the main body 10.

[0128] Accordingly, in the dishwashing and drying machine 1, the increase in the number of parts can be suppressed, and the cooling fan 60 can be easily positioned to deliver air through the air outlet 53.

[0129] (Other implementation methods)

[0130] As described above, Embodiment 1 has been presented as an example of the technology disclosed in this application. However, the technology in this disclosure is not limited to this, and can also be applied to embodiments with modifications, substitutions, additions, omissions, etc. Furthermore, the constituent elements described in Embodiment 1 above can be combined to create new embodiments.

[0131] Therefore, other implementation methods are illustrated below.

[0132] Figure 8 This is a perspective view of the base frame 20 of modified example 1, obtained from the rear. Figure 8 In the middle, to and Figure 4 The same reference numerals are used to label the same parts, and their descriptions are omitted.

[0133] like Figure 8 As shown, in the dishwashing and drying machine 1, an exhaust duct 150 may be provided instead of an exhaust duct 50. The exhaust duct 150 extends along the longitudinal direction. A side panel 150A is provided on the left side of the exhaust duct 150. The side panel 150A is configured to be opposite to and substantially parallel to the side panel 42. As a result, the exhaust gas flowing from the exhaust duct 22 into the exhaust duct 150 is guided forward along the longitudinal direction.

[0134] In this modified example, the cooling air is delivered by the air duct 70 at an angle β formed by the direction in which the cooling air is delivered and the direction in which the exhaust air is delivered. Angle β is 45 degrees or more and 90 degrees or less. Thus, the exhaust air from the dishwashing and drying machine 1 is cooled by mixing with the cooling air and flows from the front side of the main body 10 to the right side, changing its travel path. Consequently, the cooling air collides with and mixes with the exhaust air at a point where it does not reach the kick plate 92.

[0135] Figure 9 This is a perspective view of the base frame 20 of modified example 2, obtained from the rear. Figure 9 In the middle, to and Figure 4 , Figure 8 The same reference numerals are used to label the same parts, and their descriptions are omitted.

[0136] like Figure 9 As shown, if the dishwashing and drying machine 1 is equipped with an exhaust duct 150, the air outlet 53 may be located adjacent to the exhaust outlet 51. In this case, the air duct 70 and the cooling fan 60 may be located adjacent to the exhaust duct 150.

[0137] In this modified example, the cooling air is delivered by the air duct 70 at an angle γ formed by the angle between the direction of the cooling air delivery and the direction of the exhaust. The angle γ is 30 degrees or more and 60 degrees or less. Thus, the exhaust air from the dishwashing and drying machine 1 is cooled by mixing with the cooling air and flows from the front side of the main body 10 to the right side, changing its travel path. Consequently, the cooling air collides with and mixes with the exhaust air at a position that does not reach the kick plate 92.

[0138] In the above-described embodiments, the dishwashing and drying machine 1 includes: an exhaust duct 50 having an inclined side 50A; and an air guide duct 70 having an inclined air guide plate portion 72.

[0139] However, it is not limited to this. For example, the exhaust duct 50 and the air guide duct 70 may be formed in a generally straight line in the length direction and installed such that the angle between the extensions of their respective length directions is more than 30 degrees and less than 180 degrees.

[0140] In this case, the exhaust duct 50 and the air guide duct 70 may be arranged such that their respective downstream sides face each other in the direction of air flow, or the exhaust duct 50 and the air guide duct 70 may be arranged such that the downstream side of one extends towards the other.

[0141] In the above embodiment, a plurality of louver-shaped rectifiers 74 are provided inside the air outlet 53 in a crisscrossing manner in the plane and vertical direction.

[0142] However, it is not limited to this. Alternatively, the rectifier 74 may be arranged inside the air outlet 53 in a manner that intersects the plane with the bottom panel 48, or in other words, in a manner that intersects the plane with the horizontal direction. In this case, the rectifier 74 may also be formed to extend from the air outlet 53 all the way into the interior of the air guide duct 70.

[0143] Alternatively, in this case, each rectifier 74 may be arranged at an angle so that when viewed from above, it moves towards the exhaust port 51 as the inner side of the self-guided air duct 70 moves towards the air outlet 53.

[0144] Therefore, in the dishwashing and drying machine 1, the cooling air flows towards the exhaust gas, and before reaching the kick plate 92, the cooling air collides with and mixes with the exhaust gas.

[0145] In this case, each rectifier 74 can also be installed in the following manner: the angle formed by the extension line of each rectifier 74 extending along the direction of the inner side of the self-guided air duct 70 toward the air outlet 53 and the extension line extending along the direction of the exhaust port ducts 50, 150, or the extension line extending along the side of the exhaust port ducts 50, 150 in the left and right directions is 30 degrees or more and 180 degrees or less.

[0146] Alternatively, for example, the rectifier 74 may be provided inside the exhaust port 51. In this case, the rectifier 74 may be formed, for example, as a louver extending from the exhaust port 51 into the interior of the exhaust port ducts 50 and 150, to rectify the air blown out from the exhaust port 51.

[0147] Alternatively, each rectifier 74 located inside the exhaust port 51 may be arranged at an angle so that, when viewed from above, it approaches the air outlet 53 as the inner side of the exhaust port pipes 50 and 150 faces the exhaust port 51.

[0148] Therefore, in the dishwashing and drying machine 1, the exhaust flows towards the cooling air and collides with and mixes with the cooling air at a position that does not reach the kick plate 92.

[0149] In this case, each rectifier 74 can also be installed in such a way that the angle formed by the extension line of each rectifier 74 extending along the inner side of the exhaust port duct 50, 150 toward the exhaust port 51 and the extension line extending along the direction of the air guide duct 70, or the extension line extending along the side of the air guide duct 70 in the left and right directions, is more than 30 degrees and less than 180 degrees.

[0150] Alternatively, for example, in the dishwashing and drying machine 1, a rectifier 74 may be provided inside both the exhaust port 51 and the air outlet 53. In this case, each rectifier 74 may be installed in such a way that the angle formed by the extension line of the plane of the rectifier 74 located inside the exhaust port 51 extending in the direction of exhaust flow and the extension line of the plane of the rectifier 74 located inside the air outlet 53 extending in the direction of cooling air flow is 30 degrees or more and 180 degrees or less.

[0151] Alternatively, in this case, the exhaust ducts 50 and 150 and the air guide duct 70 may be formed and configured to extend along the longitudinal direction in the longitudinal direction.

[0152] Furthermore, the rectifier 74 inside the exhaust port 51 and the rectifier 74 inside the air outlet 53 can be set at any tilt angle, as long as the exhaust from the exhaust port 51 and the cooling air from the air outlet 53 can collide and mix without reaching the kick plate 92. Therefore, it is also possible for at least one of the rectifier 74 inside the exhaust port 51 or the rectifier 74 inside the air outlet 53 to be formed facing the other.

[0153] The shape formed by at least one of the internal rectifier 74 of the exhaust port 51 and the internal rectifier 74 of the air outlet 53 facing the other is, for example, a shape in which one of the internal rectifier 74 of the exhaust port 51 and the internal rectifier 74 of the air outlet 53 is inclined towards the other, or a shape in which both the internal rectifier 74 of the exhaust port 51 and the internal rectifier 74 of the air outlet 53 are inclined towards each other.

[0154] Furthermore, the so-called orientation toward the other side is not limited to the case where each rectifier 74 is oriented toward the other side. It can be formed in such a way that the extension line L1 extending along the plane of the rectifier 74 inside the exhaust port 51 and the extension line L2 extending along the plane of the rectifier 74 inside the air outlet 53 intersect when viewed from above.

[0155] The control device 30 can also control the speed or airflow of the cooling fan 60 based on the humidity inside the washing tank 14. For example, in the dishwashing and drying machine 1, at the start of the drying process, there is more washing water remaining inside the washing tank 14, so the gas discharged from the washing tank 14 is hot and humid. In this case, the control device 30 can also set the airflow of the cooling fan 60 to a predetermined value or higher.

[0156] In contrast, if a predetermined time has elapsed since the start of the drying process, a large amount of the residual cleaning water will be discharged as water vapor, resulting in lower humidity in the gas discharged from the cleaning tank 14 compared to the start of the drying process. In this case, the control device 30 can also keep the airflow of the cooling fan 60 below a predetermined value.

[0157] Therefore, in the dishwashing and drying machine 1, when the gas discharged from the washing tank 14 is highly humid, condensation on the outside of the main body 10 can be suppressed, and when the gas discharged from the washing tank 14 is low humid, the drying efficiency of the cleaned items can be improved.

[0158] The control device 30 can also control the speed or airflow of the cooling fan 60 based on the detection value of the temperature sensor 39. For example, in the dishwashing and drying machine 1, if the temperature difference between the gas discharged from the washing tank 14 and the temperature of the set space is above a predetermined value, the control device 30 can also set the airflow of the cooling fan 60 to be above a predetermined value.

[0159] In contrast, in the dishwashing and drying machine 1, when the temperature difference between the gas discharged from the washing tank 14 and the temperature of the set space is below a predetermined value, the control device 30 may also set the airflow of the cooling fan 60 to below a predetermined value or stop the rotation of the cooling fan 60.

[0160] Therefore, in the dishwashing and drying machine 1, the cooling fan 60 can be stopped when condensation is unlikely to occur, thereby improving energy efficiency and user comfort.

[0161] In Embodiment 1 described above, an embedded dishwashing and drying machine 1 is shown as an example of the "dishwashing and drying machine" of this disclosure. However, the "dishwashing and drying machine" of this disclosure is not limited to this; it may also be a dishwashing and drying machine placed under the kitchen sink, or it may be a countertop dishwashing and drying machine. In addition, for example, the "dishwashing and drying machine" of this disclosure may also be a freestanding dishwashing machine that is placed directly on the floor near the kitchen.

[0162] The processor 100 can be composed of a single processor or multiple processors. The processor 100 can also be hardware programmed to perform various actions of the dishwashing and drying machine 1. That is, the processor 100 can also be composed of, for example, an ASIC (Application Specific Integrated Circuit) or a FPGA (Field Programmable Gate Array).

[0163] Figure 3 The structure of the dishwashing and drying machine 1 shown is an example, and the specific assembly method is not particularly limited. That is to say, it is not necessarily necessary to assemble hardware corresponding to each part; it is also possible to set up a structure in which the functions of each part are implemented by a processor executing a program. In addition, some of the functions implemented by software in the above embodiments can be implemented by hardware, or some of the functions implemented by hardware can be implemented by software.

[0164] The control program 111 executed by the processor 100 can also be implemented while the control program 111 is recorded on a portable information recording medium. The information recording medium can include magnetic recording media such as hard disks, optical recording media such as CDs, USB (Universal Serial Bus) memory, SSD (Solid State Drive) and other semiconductor storage devices, but other recording media can also be used.

[0165] Furthermore, the above-described embodiments are used to illustrate the technology in this disclosure, and therefore various changes, substitutions, additions, omissions, etc., can be made within the scope of the claims or their equivalents.

[0166] (Postscript)

[0167] Based on the above description of the embodiments, the following technology can be disclosed.

[0168] (Technology 1) A dishwashing and drying machine comprising a main body having a washing tank for storing dishwashings, the main body having: an exhaust port and an exhaust port pipe, the exhaust port discharging gas from the washing tank to the outside of the main body, the exhaust port pipe guiding the gas from the washing tank to the exhaust port; a cooling fan cooling the gas discharged from the exhaust port; and an air outlet and an air guide pipe, the air outlet blowing cooling air from the cooling fan to the outside of the main body, the air guide pipe guiding the cooling air from the cooling fan to the air outlet, at least one of the exhaust port pipe and the air guide pipe being formed facing the other, or at least a portion of the exhaust port and at least a portion of the air outlet being formed facing the other.

[0169] Therefore, in a dishwashing and drying machine, it is possible to prevent the cooling air from entering the exhaust port and obstructing the exhaust of gas from the washing tank from escaping through the exhaust port from inside the main body. Thus, in a dishwashing and drying machine, it is possible to suppress the reduction in the drying efficiency of the washed items.

[0170] (Technology 2) In the dishwashing and drying machine described in Technology 1, the exhaust port pipe extends from the interior of the main body and is connected to the exhaust port, and the side of the exhaust port pipe located on the air outlet side is formed inclined towards the air outlet side as it moves from the interior of the main body toward the exhaust port.

[0171] Therefore, in the dishwashing and drying machine, the cooling air collides with and mixes with the exhaust air outside the main body. Thus, the dishwashing and drying machine can prevent the cooling air from entering the exhaust port and hindering the gas discharged from the washing tank from exiting the exhaust port inside the main body.

[0172] (Technology 3) In the dishwashing and drying machine described in Technology 1, the side of the exhaust port pipe located on the air outlet side extends parallel to the side of the opposite body from the interior of the main body toward the exhaust port.

[0173] Therefore, in the dishwashing and drying machine, the exhaust gas is smoothly discharged to the outside.

[0174] (Technology 4) In the dishwashing and drying machine described in any one of Technology 1 to Technology 3, the air duct extends from the interior of the main body and is connected to the air outlet, and the side of the air duct located on the exhaust port side is formed inclined toward the exhaust port side as it moves from the interior of the main body toward the air outlet.

[0175] Therefore, in the dishwashing and drying machine, the cooling air collides with and mixes with the exhaust air outside the main body. Thus, the dishwashing and drying machine can prevent the cooling air from entering the exhaust port and hindering the gas discharged from the washing tank from exiting the exhaust port inside the main body.

[0176] (Technology 5) In the dishwashing and drying machine described in any one of Technologies 1 to 4, the angle formed by the extension line extending along the direction of the exhaust port pipe and the extension line extending along the direction of the air guide pipe is 30 degrees or more and 180 degrees or less.

[0177] Therefore, in the dishwashing and drying machine, the cooling air collides with and mixes with the exhaust air at a location where it does not come into contact with structures located outside the dishwashing and drying machine. Thus, condensation on the outside of the dishwashing and drying machine can be suppressed.

[0178] (Technology 6) In the dishwashing and drying machine described in any one of Technologies 1 to 5, the exhaust port and the air outlet are located at different positions on the same side of the main body.

[0179] Therefore, in a dishwashing and drying machine, it is possible to prevent the gas blown from the exhaust port from flowing towards the front of the main body. Consequently, in a dishwashing and drying machine, it is possible to prevent condensation from forming and adhering to structures located in front of the dishwashing and drying machine.

[0180] (Technology 7) In the dishwashing and drying machine described in Technology 6, the air outlet and the exhaust outlet are arranged at approximately the same position in the vertical direction and are arranged at positions that are separated from each other in the horizontal direction.

[0181] Therefore, in the dishwashing and drying machine, the cooling air collides with and mixes with the exhaust air at a position where the exhaust does not come into contact with structures located in front of the dishwashing and drying machine. Thus, condensation on the outside of the dishwashing and drying machine can be suppressed.

[0182] (Technology 8) In the dishwashing and drying machine described in any one of Technologies 1 to 7, the cooling fan draws in air from the interior of the main body and blows it out from the air outlet.

[0183] Therefore, in the dishwashing and drying machine, it is possible to prevent a sharp drop in the temperature of the gas blown out of the exhaust port and to cool the gas blown out of the exhaust port. Thus, in the dishwashing and drying machine, it is possible to prevent condensation from forming on the exterior of the main body.

[0184] (Technology 9) In the dishwashing and drying machine described in any one of Technologies 1 to 8, an internal space is provided below the main body, which is separated from the washing tank. The cooling fan is provided in the internal space and is configured such that the inlet of the cooling fan faces the internal space, drawing in hot air from the internal space heated by the heat of the bottom surface of the washing tank and blowing it out from the outlet.

[0185] Accordingly, in the dishwashing and drying machine, the exhaust temperature and humidity can be reduced, and the situation where the exhaust temperature drops below a predetermined temperature relative to the outside air of the main body can be prevented, thus suppressing the formation of condensation on the outside of the main body. Furthermore, in the dishwashing and drying machine, the situation where the user comes into contact with condensed, high-temperature, and humid exhaust can be prevented.

[0186] (Technology 10) In the dishwashing and drying machine described in Technology 9, the cooling fan is fixed to the side of the main body that forms the internal space and on the side where the exhaust port is provided.

[0187] Therefore, in a dishwashing and drying machine, the length of the cooling airflow path inside the main body can be shortened, making the control of the cooling air easier and reducing pressure loss.

[0188] (Technology 11) In the dishwashing and drying machine described in any one of Technology 1 to Technology 10, the air outlet is integrally provided with the main body.

[0189] Accordingly, the cooling air delivered by the cooling fan is guided by an air duct integrally formed with the front surface of the main body. Therefore, in the dishwashing and drying machine, the increase in the number of parts can be suppressed, and the direction of the cooling air can be easily controlled.

[0190] (Technology 12) In any of the tableware washing and drying machines described in Technology 1 to Technology 11, a fixing part for fixing the cooling fan is integrally provided in the main body.

[0191] Accordingly, in a dishwashing and drying machine, the increase in the number of parts can be suppressed, and the cooling fan can be easily positioned to deliver air through the air outlet.

[0192] (Technology 13) A dishwashing and drying machine comprising a main body having a washing tank for storing dishwashings, wherein the main body is provided with: an exhaust port for discharging gas from the washing tank to the outside of the main body; a cooling fan for cooling the gas discharged from the exhaust port; and an air outlet for blowing cooling air from the cooling fan to the outside of the main body, wherein the gas discharged from the exhaust port and the cooling air blown from the air outlet are mixed by colliding with the outside of the main body.

[0193] Therefore, in a dishwashing and drying machine, it is possible to prevent the cooling air from entering the exhaust port and obstructing the exhaust of gas from the washing tank from escaping through the exhaust port from inside the main body. Thus, in a dishwashing and drying machine, it is possible to suppress the reduction in the drying efficiency of the washed items.
