  1 shows a state in which the lid 11 is closed, and FIG. 2 shows a state in which the lid 11 is opened.

  The tableware dryer 1 according to the present embodiment is mainly disposed on a main body 10, a lid body 11 that forms a drying chamber 13 together with the main body 10, a hinge 15 that supports the main body 10 so that the main body 10 can be opened and closed, and a hinge 15. An open / close detection unit 16 that detects the open / closed state of the lid 11, a tableware basket 18, and an operation unit 19 are provided. The main body 10 and the lid body 11 form a drying chamber 13. The tableware basket 18 is disposed in the drying chamber 13 and stores objects to be dried such as tableware.

  The lid 11 is composed of a transparent synthetic resin fixed lid 11a, a front lid 11b, and an intermediate lid 11c supported by the main body 10 by a hinge 15. The fixed lid 11 a is fixed to the main body 10. On the other hand, the front lid body 11b and the intermediate lid body 11c rotate sequentially around the hinge 15 as an axis. As shown in FIG. 2, the lid body 11 is stored so as to overlap in the opened state. Further, as shown in FIG. 1, when the lid 11 is closed, the front lid 11 b and the intermediate lid 11 c are sequentially rotated forward one tableware dryer to seal the drying chamber 13.

  In the present embodiment, the opening side of the lid 11 is referred to as the front (front) side, and the fixing portion side of the lid 11 is referred to as the back side. Further, the surfaces orthogonal to the near side and the far side are referred to as side surfaces, respectively.

  The tableware basket 18 is made of stainless steel, for example, and is detachably disposed in the drying chamber 13. In the tableware basket 18, a stand 21 for storing tableware such as chopsticks and spoons is arranged.

  The main body 10 has a rectangular container shape made of, for example, synthetic resin, and the inside of the main body 10 and the drying chamber 13 are partitioned by a partition plate 32 that forms the bottom surface of the drying chamber 13. The interior of the main body 10 is a space other than the drying chamber 13 and refers to a lower part than the partition plate 32. As shown in FIG. 3, the partition plate 32 has a drain hole 33 for draining moisture generated in the drying chamber 13 (moisture adhering to an object to be dried) into the main body 10. The partition plate 32 has an inclination such that the position where the drain hole 33 is provided is the lowest (closer to the bottom surface of the main body 10) in order to allow moisture to flow into the drain hole 33. The water drained from the drain hole 33 is collected in the water receiving cup 34 disposed inside the main body 10.

  As shown in FIG. 2, the main body 10 has a drawer 41 on the right front side of the tableware dryer 1 in the figure. The drawer 41 is provided with a storage chamber 41 a for storing an electrostatic mist generator 43 (negative ion generator) and an air inlet 41 b of the blower 44. The electrostatic mist generating device 43 is a device that generates electrostatic mist (mist charged by negative ions) having a sterilizing action for the object to be dried and the drying chamber 13. The configurations of the electrostatic mist generator 43 and the drawer 41 will be described later.

  The tableware dryer 1 is integrally provided with a drawer 41 and a storage chamber 41a of the electrostatic mist generator 43 and an air inlet 41b. Moreover, it is preferable that the electrostatic mist generator 43 (drawer 41) is disposed at a position facing the drainage hole 33 (water receiving cup 34) through the blower 44 and the heater 45 inside the main body 10. For example, as shown in FIG. 4, the electrostatic mist generator 43 is provided on the right side inside the main body 10, and the drain hole 33 is provided on the left side. This is because the capacity of the water receiving cup 34 installed in the vicinity of the drain hole 33 is not reduced due to the provision of the electrostatic mist generating device 43 and the relationship with other internal components of the main body 10.

  As shown in FIG. 4, a blower 44, a heater 45, and an electrostatic mist generator 43 are mainly provided inside the main body 10.

  The blower 44 includes a motor 44a and a fan 44b rotated by the motor 44a. The blower 44 blows air sucked from an intake port 41 b provided in the drawer 41 to the heater air passage 47 and the electrostatic mist air passage 48. The heater air passage 47 and the electrostatic mist air passage 48 are provided inside the main body 10. The heater air passage 47 is an air passage for blowing air to the heater 45. The electrostatic mist air passage 48 is an air passage for blowing air to the electrostatic mist generator 43. The electrostatic mist air passage 48 is configured to have a smaller air volume than the heater air passage 47, as long as it can blow a sufficient amount of air to carry the electrostatic mist to the drying chamber 13.

  The air heated by the heater 45 is blown out from the warm air outlet 49 (see FIG. 2) by the air blown from the heater air passage 47, and dries the object to be dried in the drying chamber 13. The electrostatic mist generated by the electrostatic mist generator 43 is blown out from the electrostatic mist outlet 50 (see FIG. 2) together with the air blown from the electrostatic mist air passage 48. This electrostatic mist is supplied into the drying chamber 13 to sterilize the object to be dried and the drying chamber 13.

  Note that the electrostatic mist air passage 48 may have a variable air passage width and adjust the air volume by adjusting the air passage width. The heater air passage 47 and the electrostatic mist air passage 48 may be branched downstream of the heater 45. The heater air passage 47 and the electrostatic mist air passage 48 are not independent and may be a common air passage. In this case, it is preferable to dispose the electrostatic mist generator 43 on the downstream side of the heater 45.

  As shown in FIG. 2, the main body 10 has a warm air outlet 49 on the back wall surface 10 a of the drying chamber 13 and an electrostatic mist outlet 50 on the right wall surface 10 b. The electrostatic mist outlet 50 is preferably provided in the vicinity of the hot air outlet 49 (the back wall surface 10a provided with the hot air outlet 49). Since the electrostatic mist blown out from the electrostatic mist outlet 50 is carried by the hot air blown out from the hot air outlet 49, the electrostatic mist can be filled in the drying chamber 13, and the sterilization performance is kept high. be able to. In addition, you may provide the warm air blower outlet 49 and the electrostatic mist blower outlet 50 in the same plane (for example, the back wall surface 10a of the drying chamber 13).

  Further, the hot air outlet 49 and the electrostatic mist outlet 50 are located below the tableware placement surface of the tableware basket 18 in the main body 10 and are disposed between the bottom surface of the tableware basket 18 and the partition plate 32. Since there is no obstacle such as an object to be dried, the hot air outlet 49 and the electrostatic mist outlet 50 can efficiently fill the entire drying chamber 13 with the hot air and the electrostatic mist.

  The main body 10 is provided with an operation unit 19 for a user to input various instructions.

  FIG. 5 is a diagram illustrating an example of an operation unit provided in the tableware dryer according to the embodiment of the present invention.

  As shown in FIG. 5, the operation unit 19 of the tableware dryer 1 includes an on / off button 51, a drying time setting button 53a, and a sterilization drying button 53b. The on / off button 51 receives an instruction to turn on or off the tableware dryer 1. The drying time setting button 53a receives the setting of the operation time of the drying operation. The setting value of the drying time setting button 53a changes, for example, 20 minutes, 40 minutes, and 60 minutes each time an input is received. The sterilization / drying button 53b has two operation courses: a “dry operation course” in which only drying with warm air is performed, and a “dry / sterilization operation course” in which drying with hot air and sterilization with electrostatic mist are performed. Accepts an instruction to switch. Detailed description of each driving course will be described later.

  The operation unit 19 includes a water supply confirmation lamp 54, a drying operation lamp 55, and a sterilization operation lamp 56. The water supply confirmation lamp 54 is a lamp that notifies water supply to the tank 61 of the electrostatic mist generator 43. The drying operation lamp 55 is a lamp that notifies the operation time of the drying operation. The drying operation lamp 55 includes a 20 minute lamp 55a indicating that the set operation time is 20 minutes, a 40 minute lamp 55b indicating 40 minutes, and a 60 minute lamp 55c indicating 60 minutes. The sterilization operation lamp 56 is a lamp indicating that the sterilization operation is performed together with the drying operation.

  FIG. 6 is a perspective view illustrating a hinge and an open / close detection unit of the tableware dryer according to the present invention.

  FIG. 7 is a perspective sectional view showing a hinge and an open / close detection unit of the tableware dryer according to the present invention.

  FIG. 8 is a cross-sectional view showing the hinge of the tableware dryer according to the present invention.

  9 to 11 are cross-sectional views showing an open / close detection unit of the tableware dryer according to the present invention.

  9 is a view showing a state in which the lid body 11 is fully opened, FIG. 10 is a view showing the lid body 11 being closed or being opened, and FIG. 11 is a state in which the lid body 11 is closed. FIG.

First, as shown in FIGS. 6 to 8, the hinge 15 of the tableware dryer 1 includes an inner sleeve 61 formed on the fixed lid 11a fixed to the main body 10 and an intermediate sleeve formed on the intermediate lid 11c. 62, a journal bearing portion 63 formed on the front cover 11b, and a rotation restricting member 65 fixed to the front cover 11b. The hinge 15 pivotally supports the intermediate lid 11c on the fixed lid 11a so as to be freely opened and closed by an intermediate sleeve 62 superimposed on the outer periphery of the inner sleeve 61. Further, the hinge 15 pivotally supports the front lid body 11b on the fixed lid body 11a via the intermediate lid body 11c by the journal bearing portion 63 having the outer periphery of the intermediate sleeve 62 as the journal portion.
As shown in FIGS. 9 to 11, the rotation restricting member 65 is an annular member that surrounds the rotation center of the hinge 15, and includes locking protrusions 66 and 67 that rotate together with the journal bearing portion 63. On the other hand, the intermediate lid body 11 c includes locking protrusions 68 corresponding to the locking protrusions 66 and 67. The locking projections 66 and 67 and the locking projection 68 are hooked at an appropriate rotation phase when the lid body 11 is opened or closed, and once the opening and closing of the intermediate lid body 11c and the front lid body 11b is restricted, and the lid body. 11 is prevented from opening and closing vigorously. On the other hand, the locking projections 66 and 67 and the locking projection 68 are released when the force for opening and closing the lid body 11 is appropriately increased, and the restriction of the intermediate lid body 11c and the front lid body 11b is released to open and close. forgive.

  On the other hand, as shown in FIG. 6 to FIG. 11, the open / close detection unit 16 of the tableware dryer 1 moves by being pressed by the action unit 71 interlocked with the opening / closing operation of the lid 11 and the action unit 71. A pressing portion 72 that detects the open / closed state of the body, a sleeve 73 that protrudes from the outer surface of the main body 10 and holds the pressing portion 72 slidably, and an arm 75 that swings in conjunction with the pressing portion 72. , And a micro switch 76 (switch) whose contacts are opened and closed by the arm 75.

  The open / close detection unit 16 includes a switch box 77 in which an arm 75 and a micro switch 76 are accommodated.

  The action portion 71 is a tongue piece formed on the rotation restricting member 65 of the hinge 15 and pivots around the rotation axis of the hinge 15 in conjunction with opening and closing of the lid body 11 (more specifically, the front lid body 11b). To do. Moreover, the action part 71 is a cam which has the press surface 71a which presses the press part 72 gradually or stepwise in the direction away from the rotating shaft center of the hinge 15, when the cover body 11 approaches a fully closed position. The open / close detection unit 16 detects that the lid 11 is fully closed by appropriately adjusting the shape of the action part 71 (appropriately extending or shortening the pressing surface 71a in the turning direction of the action part 71). The play relating to the opening degree and detection can be set as appropriate.

  The pressing portion 72 is formed in a rod shape, and the longitudinal direction, which is the moving direction thereof, is directed vertically, and is disposed below the hinge 15 through the inside and outside of the main body 10 from the inside of the switch box 77. When the lid 11 approaches the fully closed position, the pressing portion 72 is pushed gradually or stepwise in the direction away from the rotation axis of the hinge 15 by the action portion 71 and moves to the inside of the main body 10. The pressing portion 72 is urged in the direction of the rotation axis of the hinge 15 by an elastic body 78 such as a coil spring. The urging force of the elastic body 78 is sufficiently smaller than the pressing force by the action portion 71.

  The sleeve 73 is held by a column provided outside the switch box 77. The sleeve 73 is disposed in the through hole 10c of the main body 10 and slidably holds the rod-shaped pressing portion 72, while filling a gap between the pressing portion 72 and the main body 10 to allow foreign matters such as moisture to enter the main body. This prevents the pressing portion 72 from moving up and down smoothly.

  The arm 75 is swingably supported in the switch box 77 and is connected to the pressing portion 72. The arm 75 converts the movement (vertical movement) of the pressing portion 72 by the action portion 71 into a rotational motion around the swing axis of the arm 75. Further, the arm 75 is formed by bending the swinging free end side and directing it upward from the swing axis.

  The micro switch 76 is disposed on the side of the pressing portion 72 and is disposed above the swing shaft of the arm 75. The micro switch 76 has a contact that is opened and closed by swinging the arm 75.

  The switch box 77 is a cover that protects the microswitch 76, and includes a partition wall 81 that partitions the internal space into two spaces. The partition wall 81 is a wall that hangs in a substantially vertical direction from the top wall of the switch box 77, and includes a link mechanism housing chamber 82 that houses the inside of the switch box 77 close to the pressing portion 72 and the swing axis of the arm 75. The switch chamber 83 is divided into a micro switch 76 and a free end side of the arm 75. The partition wall 81 prevents the water from reaching the micro switch 76 even if moisture enters the switch box 77 by being transmitted through the pressing portion 72.

  The open / close detection unit 16 of the tableware dryer 1 configured as described above is configured by microscopically sequentially operating the open / close state of the lid 11 through the action unit 71 as a cam, the pressing unit 72 and the arm 75 as a link mechanism. The signal is transmitted to the switch 76 to electrically open and close the contact.

  FIG. 12 is a functional block diagram illustrating a tableware dryer according to an embodiment of the present invention.

  As shown in FIG. 12, the tableware dryer 1 according to this embodiment includes a timer 88, a memory 89, and a power-on detection unit 91. Lighting control of each lamp is performed by the control unit 87. The timer 88 measures time required when performing a drying operation and a sterilization operation described later. The memory 89 stores an elapsed period since the previous driving course and the electrostatic mist generator 43 were installed. The power-on detection unit 91 detects whether a power plug (not shown) is inserted into a household outlet and whether the tableware dryer 1 is turned on.

FIG. 13 is a schematic circuit diagram showing a power supply system of the electrostatic mist generator of the tableware dryer according to the embodiment of the present invention.
As shown in FIG. 13, the tableware dryer 1 supplies electric power to the electrostatic mist generator 43 through the high voltage power source 92 from the control unit 87 connected to the AC power source E.
The high voltage power source 92 is a power source that generates a DC negative voltage of about 4 kV to about 10 kV, for example, and is disposed at a predetermined position inside the main body 10 of the tableware dryer 1.
The electrostatic mist generator 43 is electrically connected to the negative electrode of the high voltage power source 92.
The micro switch 76 of the open / close detection unit 16 is provided on one power line 93 that electrically connects the control unit 87 and the high voltage power source 92. When the lid 11 is in a closed state, the open / close detection unit 16 closes the contact of the micro switch 76 and makes the control unit 87 and the high voltage power source 92 conductive. On the other hand, when the lid 11 is in the opened state, the open / close detection unit 16 opens the contact of the micro switch 76 to block the circuit between the control unit 87 and the high voltage power source 92.
In addition, the tableware dryer 1 includes a resistor 95 that electrically connects (directly connects) the electrostatic mist generator 43 and the control unit 87 across the high voltage power source 92. The electrostatic mist generating device 43 is grounded via the control unit 87 by the resistor 95 regardless of the operation of the high voltage power source 92. The resistor 95 has an electrical resistance in the range of about 10 MΩ to about 500 MΩ, and preferably has an electrical resistance of about 100 MΩ.

  Next, the drawer 41 and the electrostatic mist generator 43 housed in the drawer 41 will be described.

  FIG. 14 is a perspective view showing the appearance of the drawer and electrostatic mist generator of the tableware dryer according to the embodiment of the present invention.

  As shown in FIG. 14, the air inlet 41 b of the blower 44 is provided on the front side of the drawer 41. An intake filter 96 is detachably disposed at the intake port 41b. A storage chamber 41a for storing the electrostatic mist generating device 43 is provided on the back side of the drawer. The electrostatic mist generator 43 is detachably disposed from the storage chamber 41a.

  FIG. 15 is an exploded perspective view showing an electrostatic mist generator of a tableware dryer according to an embodiment of the present invention.

  As shown in FIG. 15, the electrostatic mist generator 43 mainly includes a tank 61, a water wick 97, a water retention body 98, a connection electrode 99, and a mist generation electrode 101.

  The tank 61 stores a predetermined amount of water such as tap water. The tank 61 is sealed with a tank lid 103 via a packing 102. The tank lid 103 can be removed from the tank 61, and water can be appropriately supplied by the user. The tank lid 103 is provided with an insertion hole 103a. The wick 97 held by the mist generating electrode case 105 is immersed in the water in the tank 61 through the insertion hole 103a. In the mist generating electrode case 105, a water retention body 98 having water absorption and water retention is disposed. The water retaining body 98 is in contact with the wick 97 and holds the water pumped from the tank 61 by the wick 97. The water retaining body 98 is formed of, for example, a ceramic material, a porous body of a synthetic resin material or a metal material, or a fiber body.

  The mist generating electrode 101 is disposed so as to protrude upward with respect to the water retaining body 98. The mist generating electrode 101 is arranged in a state of being held on the mist generating electrode base 106. The mist generating electrode 101 is formed in a rod-like body, and is formed of, for example, ceramic fiber, organic fiber, or metal fiber. A plurality of mist generating electrodes 101 are provided according to the discharge amount of electrostatic mist. Note that the height of the mist generating electrode 101 and the water draw core 97 extending in the height direction of the tableware dryer 1 affects the dimensions of the tableware dryer body. For this reason, by suppressing the height of the mist generating electrode 101 and the scooping water core 97 as much as possible, the height of one tableware dryer can be suppressed and downsizing can be realized. The mist generating electrode 101 is preferably 14 mm or less in height, for example. The pumping core 97 is preferably, for example, 35 mm or less in height.

  The mist generating electrode case 105 holds a connection electrode 99 that can be connected to the negative electrode of the high-voltage power supply 92. The connection electrode 99 is connected to the water holding body 98 and charges the water holding body 98 negatively.

  The structure above the tank lid 103 of the electrostatic mist generating device 43 (mist generating electrode case 105, pumping core 97, water retaining body 98, mist generating electrode base 106, mist generating electrode 101 and connection electrode 99) is an electrode cover 107. Covered by. The electrode cover 107 has a protrusion 107 a that covers the connection electrode 99 extending in the insertion direction of the drawer 41. The protrusion 107 a has a structure (function) that contacts an electrostatic mist generator detection switch 108 (described later) provided in the main body 10 and detects whether or not the electrostatic mist generator 43 is installed. By providing the electrode cover 107 with a structure in contact with the electrostatic mist generator detection switch 108, the structure can be simplified.

  In addition, about the structure of the electrostatic mist generator 43, it described in Unexamined-Japanese-Patent No. 2006-212156 (Generator of a functional component containing mist) and Unexamined-Japanese-Patent No. 2008-212887 (electrostatic atomizer), for example. Technology can be applied.

  FIG. 16 is a longitudinal sectional view showing the relationship between the inside of the main body of the tableware dryer and the electrostatic mist generator according to the embodiment of the present invention.

  In the main body 10, a connection terminal 109 connected to the negative electrode of the high voltage power supply 92 is disposed at a position corresponding to the connection electrode 99. The connection terminal 109 is covered with a connection terminal case 111 from the viewpoint of safety. Further, an electrostatic mist generating device detection switch 108 (detecting unit) for detecting that the electrostatic mist generating device 43 is installed in the main body 10 together with the drawer 41 is provided further to the inner side of the main body 10 than the connection terminal case 111. Provided.

  The electrostatic mist generator detection switch 108 includes a switch shaft 112 and a micro switch 113. The switch shaft 112 is movable in the direction in which the drawer 41 is put in and out (the direction of arrow A in FIG. 9). The switch shaft 112 comes into contact with the lever of the micro switch 113 when the electrostatic mist generator 43 is installed and pushed out by the protrusion 107a of the electrode cover 107 in the back direction of the main body 10 (right direction in the drawing). As a result, the micro switch 113 is turned on, and the mounting of the electrostatic mist generating device 43 is detected.

  When the electrostatic mist generator 43 is installed in the main body 10 together with the drawer 41, the connection electrode 99 comes into contact with the connection terminal 109. Further, the projection 107 a of the electrode cover 107 comes into contact with the switch shaft 112, and the installation of the electrostatic mist generating device 43 is detected by the microswitch 113. Then, a voltage is applied to the connection electrode 99 connected to the negative electrode of the high voltage power source 92. When the water retention body 98 connected to the connection electrode 99 is negatively charged, the current flows in search of a place where discharge is most likely to occur. In general, electrons have a property of gathering at a point where the tip is sharp or a place with excellent electrical conductivity such as metal. For this reason, the electrons gather at the mist generating electrode 101. Then, a spontaneous discharge phenomenon occurs in the mist generating electrode 101, and an ion wind is generated by the discharge action. Using this ion wind, water is released into the air from the mist generating electrode 101 as a fine mist invisible to the pico size or nano size (about 500 pm to 5000 pm).

  Next, an operation course of the tableware dryer 1 will be described.

  FIG. 17 is a chart for explaining an example of each operation course of the tableware dryer according to the embodiment of the present invention.

  The drying operation course includes a warm air operation for drying an object to be dried by air (hot air) heated by the heater 45 and blown from the blower 44, and a cooling operation for cooling the dry matter with the air blown from the blower 44. This course consists of For example, in the drying operation course, the heater 45 and the blower 44 are turned on from the start of operation, the hot air operation is continued for 50 minutes, and then the heater 45 is turned off (cooling operation is continued for 10 minutes). (60 minutes in total). In the drying operation course, the electrostatic mist generator 43 remains off.

  The drying / sterilization operation course is a course for performing the sterilization operation in which electrostatic mist is blown out in addition to the hot air operation and the cooling operation. For example, in the drying / sterilization operation course, the electrostatic mist generating device 43 is turned on 40 minutes after the drying operation, the sterilizing operation is continued for 10 minutes, and thereafter (10 minutes before the end of the operation) It is turned off. The operations of the heater 45 and the blower 44 in the drying / sterilization operation course are the same as in the drying operation course.

  Here, the control unit 87 performs switching between the drying operation course and the drying / sterilization operation course and lighting control of each lamp based on an instruction from the user to each button. A detailed operation of the tableware dryer 1 performed based on the control of the control unit 87 after power is supplied to the tableware dryer 1 will be described.

  FIG. 18 is a flowchart for explaining power-on (ON) post-processing executed by the tableware dryer according to the embodiment of the present invention.

  In step S1, the control unit 87 determines whether or not the power to the tableware dryer is turned on. Specifically, the control unit 87 determines whether or not the power-on detection unit 91 detects that the power is turned on. When it is determined that the power is not turned on (NO in step S1), the controller 87 waits until the power is turned on.

  On the other hand, when it determines with the control part 87 having been turned on (YES of step S1), the tableware dryer 1 is made into a standby state in step S2. The standby state is a state in which the blower 44 and the heater 45 are ON, and each lamp (water supply confirmation lamp 54, drying operation lamp 55, sterilization operation lamp 56) is turned off. In step S3, the controller 87 determines whether or not the on / off button 51 has been turned on. When it is determined that the on / off button 51 is still in the OFF state (NO in step S3), the control unit 87 returns to the power determination step S1 and repeats the subsequent processing.

  On the other hand, when it is determined that the on / off button 51 is turned on (YES in step S3), the control unit 87 determines whether or not the electrostatic mist generating device 43 is installed in step S4. Specifically, the control unit 87 determines whether or not the electrostatic mist generator detection switch 108 has detected the installation of the electrostatic mist generator 43. When it is determined that the electrostatic mist generator 43 has been installed (YES in step S4), the controller 87 proceeds to the drying operation process (FIG. 19). On the other hand, when it is determined that the electrostatic mist generator is not installed (NO in step S4), the controller 87 cannot normally perform the drying / sterilization operation course. Proceed to the electrostatic mist generator installation notification process (FIG. 22) that prompts the installation.

  FIG. 19 is a flowchart illustrating a drying operation process executed by the tableware dryer according to the embodiment of the present invention.

  Since the user often selects the same driving course as the previous one, the tableware dryer 1 automatically drives the previous driving course when the on / off button 51 is turned on for the sake of convenience. I am doing so. Specifically, in step S <b> 11, the control unit 87 determines whether or not the previous driving course is stored in the memory 89. When it is determined that the previous operation course is stored in the memory 89 (YES in step S11), the control unit 87 determines whether or not the stored course is a dry operation course in step S12. . When it is determined that the stored course is not the dry operation course, that is, the sterilization operation course (NO in step S12), the control unit 87 proceeds to the sterilization operation process (FIG. 20). When it is determined that the stored course is the drying operation course (YES in Step S12), the controller 87 turns on the heater 45 and the blower 44 in Step S13. Further, the control unit 87 turns on the drying operation lamp 55 corresponding to the operation time of the previous drying course. Thereafter, the process proceeds to step S16.

  When it is determined in step S11 that the previous operation course is not stored in the memory 89 (NO in step S11), the controller 87 turns on the heater 45 and the blower 44 in step S14 and starts the hot air operation. . Moreover, the control part 87 lights the 20 minute lamp 55a which shows the operating time 20 minutes as an initial setting here.

  In step S15, the control unit 87 resets a timer 88 for measuring a time such as an operation time. In step S16, the control unit 87 determines whether or not the operation time set for the hot air operation has elapsed. The time set for the hot air operation is, for example, the time from the start of operation to 10 minutes before the end of operation. When it is determined that the operation time set for the warm air operation has elapsed (YES in step S16), the control unit 87 maintains the blower 44 ON in step S17 in order to cool the heated tableware and the like. Then, the heater 45 is turned off and the cooling operation is started. Moreover, the control part 87 blinks the dry operation lamp 55 in lighting. This is to notify the user that the cooling operation is being performed.

  In step S <b> 18, the control unit 87 stores the current driving course in the memory 89. When the time set for the cooling operation (for example, 10 minutes) has elapsed, the control unit 87 returns to the standby step 2 of the power-on post-processing (FIG. 18) and ends the drying operation.

  On the other hand, since the user may desire to change the drying time immediately after starting the operation or during the operation depending on the amount of the tableware or the like, the drying time can be changed as appropriate. Specifically, the following steps (S16, S19, S20 to S23) are performed.

  When it is determined that the operation time set for the hot air operation has not elapsed (NO in step S16), the control unit 87 performs an operation for setting the drying operation time using the drying time setting button 53a in step S19. It is determined whether or not.

  When it is determined that the operation of the drying time setting button 53a is performed (YES in Step S19), the control unit 87 determines whether or not the drying operation time is set to 40 minutes in Step S20. When it is determined that the drying operation time is set to 40 minutes (YES in step S20), the control unit 87 proceeds to step S23. When it is determined that the drying operation time is not set to 40 minutes (NO in step S20), the control unit 87 determines whether or not the drying operation time is set to 60 minutes in step S21. When it is determined that the drying operation time has been set to 60 minutes (YES in step S21), the control unit 87 proceeds to step S23. When it is determined that the drying operation time is not set to 60 minutes (NO in step S21), the control unit 87 determines whether or not the drying operation time is set to 20 minutes in step S22. When determining that the drying operation time is not set to 20 minutes (NO in step S22), the control unit 87 returns to step S20 and repeats steps S20 to S22 until the drying time is set.

  When it is determined that the drying operation time has been set (YES in steps S20 to S22), the control unit 87 maintains the heater 45 and the blower 44 on in step S23. Further, the control unit 87 turns on the drying operation lamp 55 corresponding to the set drying time. Thereafter, the process returns to step S16.

  On the other hand, since the user may desire to switch the operation to the sterilization / dry operation course immediately after starting the operation of the dry / driving course or during the operation, in order to be able to change the driving course as appropriate, When it is determined that the operation of the drying time setting button 53a is not performed in step S19 (NO in step S19), the control unit 87 determines whether or not the sterilization drying button 53b is turned on in step S24. When it is determined that the sterilization drying button 53b is turned on (YES in Step S24), the control unit 87 proceeds to the sterilization operation process (FIG. 20).

  At this time, when it is determined that the sterilization drying button 53b is not turned on (NO in Step S24), the control unit 87 determines whether or not the electrostatic mist generating device 43 is removed in Step S25. When it is determined that the electrostatic mist generator 43 has not been removed (NO in step S25), the control unit 87 returns to step S16 and repeats the subsequent processes. When it is determined that the electrostatic mist generator 43 has been removed (YES in step S25), the controller 87 cannot normally perform the sterilization / drying operation course, so the electrostatic mist generator installation notification process (FIG. Proceed to 15).

  FIG. 20 is a flowchart for explaining a sterilization operation process executed by the tableware dryer according to the embodiment of the present invention.

  FIG. 21 is a flowchart for explaining the sterilization operation process executed by the tableware drier according to the embodiment of the present invention following FIG.

  In step S31, after the power is turned on (YES in step S1 of the power-on post-processing (FIG. 18)), the control unit 87 determines whether or not the electrostatic mist generator 43 has been installed again. . Since this step S31 cannot directly detect that the tableware dryer 1 does not have a water amount sensor or a weight sensor, it is stored in the tank 61 of the electrostatic mist generator 43. This is a process for determining whether or not the tank 61 is indirectly supplied with water depending on whether or not the electrostatic mist generator 43 is removed. That is, if the electrostatic mist generator 43 is not installed after being removed, the tank 61 is not supplied with water, and normal operation cannot be performed. For this reason, when it determines with the control part 87 not being installed after the electrostatic mist generator 43 was removed (NO of step S31), it progresses to step S33.

  On the other hand, if the control unit 87 determines that the electrostatic mist generating device 43 is installed after the power is turned on (YES in step S31), it is predetermined after the electrostatic mist generating device 43 is installed in step S32. It is determined whether or not a period (here 1 week) has elapsed. This step S32 has passed a predetermined period since it is not possible to directly detect that the water is stored in the tank 61 of the electrostatic mist generator 43 in the case where the water amount sensor or the weight sensor is not provided. This is a process for determining whether or not the water in the tank 61 is emptied indirectly. For this reason, the predetermined period is preferably set to a period in which the water in the tank 61 is not completely emptied when, for example, normal use (for example, operation three times a day) is performed.

  Here, when the control unit 87 is installed after the electrostatic mist generating device 43 is removed, the elapsed time since the installation is measured by the timer 88, and the user is notified when a predetermined period has elapsed. By this notification, the user can be informed that the water needs to be supplied before the water in the tank 61 becomes empty, and the water supply is regularly performed even when the period of the sterilization drying operation course becomes long. , The water in the tank 61 is exchanged, and the tank 61 can be kept clean. Specifically, when the control unit 87 determines that one week has elapsed since the installation of the electrostatic mist generator 43 (YES in step S32), the notification 87 blinks the water supply confirmation lamp 54 in step S33. To do.

  Next, in step S34, the control unit 87 determines whether or not the electrostatic mist generating device 43 is installed after being removed. When the controller 87 determines that the electrostatic mist generator 43 has been installed after being removed (YES in step S34), it is considered that water has been supplied into the tank 61, and a standby step for power-on post-processing (FIG. 18). Returning to S2, the controller 87 turns off the blower 44 and the heater 45, and turns off the lamps.

  If the controller 87 determines that the electrostatic mist generator 43 is not installed after being removed (NO in step S34), water is not supplied into the tank 61, so in step S35, the drying time is set. It is determined whether or not an operation for setting the drying operation time has been performed by the button 53a. If the controller 87 determines that the operation of the drying time setting button 53a has been performed (YES in step S35), the sterilization / drying operation course may not be performed normally, but the water is stored in the tank 61. Since the drying operation course can be normally performed even if not, the operation proceeds to the operation time setting step S20 of the drying operation processing (FIG. 19). When the operation of the drying time setting button 53a is performed, the control unit 87 considers that the user intends to cancel the drying / sterilization operation course and perform the drying operation course.

  On the other hand, when it is determined that the operation of the drying time setting button 53a is not performed (NO in step S35), the control unit 87 determines that the predetermined time T1 (for example, 10 minutes) has elapsed from the blinking of the water supply confirmation lamp 54 in step S36. It is determined whether or not it has elapsed. When it is determined that the time T1 has not elapsed (NO in step S36), the control unit 87 returns to step S34 and repeats the subsequent processing in order to continuously notify the user that water supply is necessary. On the other hand, when it is determined that the time T1 has elapsed (YES in step S36), the control unit 87 determines that there is no need to continue notification such as the user leaving the place, and the power supply Returning to the standby step 2 of the post-ON processing (FIG. 18), the blinking of the water supply confirmation lamp 54 is stopped.

  When it is determined that one week has not elapsed since the electrostatic mist generator 43 was installed after the power was turned on in step S32 (NO in step S32), the controller 87 turns off the heater 45 and the blower 44 in step S37. The sterilization operation lamp 56 is turned on while the drying / sterilization operation course is started. In step S38, the controller 87 determines whether or not the electrostatic mist generator 43 has been removed. When it is determined that the electrostatic mist generating device 43 has been removed (YES in step S38), the control unit 87 cannot perform normal operation. In step S39, the control unit 87 turns off the heater 45 and the blower 44. Further, the control unit 87 turns off the sterilization operation lamp 56. Thereafter, the process proceeds to an electrostatic mist generator installation notification process (FIG. 22).

  If the controller 87 determines in step S38 that the electrostatic mist generator 43 has not been removed (NO in step S38), in step S40, an operation for setting the drying operation time is performed using the drying time setting button 53a. It is determined whether or not. When it is determined that the operation of the drying time setting button 53a has been performed (YES in Step S40), the control unit 87 turns off the sterilization operation lamp 56 in Step S41. Thereafter, the process proceeds to the operation time setting step S20 of the drying operation process (FIG. 19).

  On the other hand, when it is determined that the operation of the drying time setting button 53a is not performed (NO in step S40), the control unit 87 starts the warm air operation (after the heater 45 and the blower 44 are turned on) in step S42. ) It is determined whether or not a predetermined time T2 has elapsed. The predetermined time T2 is a preset time from the start of the hot air operation (from the drying operation process (from timer reset step S15 in FIG. 19) to the start of the sterilization operation (in FIG. 17, 40 minutes). When the control unit 87 determines that the time T2 has not elapsed (NO in step S42), the control unit 87 returns to step S38.

  On the other hand, when it is determined that the time T2 has elapsed (YES in step S42), the controller 87 turns on the electrostatic mist generator 43 in step S43 as shown in FIG. That is, the control unit 87 starts the sterilization operation in parallel with the drying operation. Here, the reason for starting the electrostatic mist generating device 43 after the time T2 from the start of the sterilization / drying operation course is that the electrostatic mist is charged on the metal tableware or the tableware basket 18, but the humidity is high. This is because the applicant discovered that the amount of charge is reduced in the state, so that the inside of the drying chamber 13 is brought into a high humidity state by the hot air operation before the sterilization operation. In step S44, the controller 87 determines whether or not the electrostatic mist generator 43 has been removed. When it is determined that the electrostatic mist generating device 43 has been removed (YES in step S44), the controller 87 cannot perform normal operation. Therefore, in step S39 (FIG. 20), the controller 45, the blower 44, and the electrostatic The mist generator 43 is turned off. Further, the control unit 87 turns off the sterilization operation lamp 56. Thereafter, the process proceeds to an electrostatic mist generator installation notification process (FIG. 22).

  On the other hand, if the controller 87 determines that the electrostatic mist generator 43 has not been removed (NO in step S44), in step S45, an operation for setting the drying operation time is performed by the drying time setting button 53a. It is determined whether or not. When it is determined that the operation of the drying time setting button 53a has been performed (YES in Step S45), the control unit 87 turns off the electrostatic mist generating device 43 in Step S41 (FIG. 20). Further, the control unit 87 turns off the sterilization operation lamp 56. Thereafter, the process proceeds to the operation time setting step S20 of the drying operation process (FIG. 19), and shifts to the drying operation. This is because when the operation of the drying time setting button 53a is performed, the tableware dryer 1 considers that the user intends to cancel the drying / sterilization operation course and operate the drying operation course.

  When it is determined that the operation of the drying time setting button 53a has not been performed (NO in step S45), the control unit 87 starts the sterilization operation in step S46 (the electrostatic mist generator 43 is turned on). It is determined whether or not a predetermined time T3 has elapsed. The predetermined time T3 is a preset time for determining the end of the sterilization operation (10 minutes in FIG. 17). When it is determined that the time T3 has not elapsed since the start of the sterilization operation (NO in step S46), the control unit 87 returns to step S44.

  When it is determined that the time T3 has elapsed since the start of the sterilization operation (YES in Step S46), the control unit 87 turns off the heater 45 and the electrostatic mist generating device 43 in Step S47. That is, the controller 87 starts the cooling operation. Here, the applicant has discovered a phenomenon in which the charge amount of the metal tableware, the tableware basket 18 and the like is reduced by making the inside of the drying chamber 13 high temperature and high humidity in advance. However, even if ions are generated in a high-humidity state, there is a possibility that a very small amount of charge that is not felt by humans may remain in the metal tableware or the tableware basket 18. Therefore, this cooling operation is for cooling the heated tableware and the like, but the electrostatic mist generator 43 is also turned off, so that this charging is spontaneously discharged in parallel with the cooling operation, which is safe for the user. To enhance the sex. Further, the applicant has discovered that the electrostatic charges of the metal tableware and the tableware basket 18 are quickly discharged by the electrostatic mist generator 43 grounded through the resistor 95. For example, the charged potential of metal tableware or tableware basket 18 immediately after the end of the sterilization operation may reach about 1.0 kV. Then, when the charged metal tableware or tableware basket 18 is naturally discharged to 0.1 kv or less, it takes about 10 minutes to about 15 minutes. On the other hand, when the electrostatic mist generating device 43 is grounded by the resistor 95, the charged potential of the metal tableware, the tableware basket 18 and the like is secured while ensuring the amount of generated electrostatic mist that can maintain the desired sterilization performance. It is possible to quickly discharge to 0.1 kv or less. Specifically, in the resistor 95 having an electric resistance of about 500 MΩ, the charging potential of the metal tableware or the dish basket 18 is about 3 seconds to about 5 seconds, and in the resistor 95 having an electric resistance of about 100 MΩ in about 1 second. Can be discharged.

  In step S48, the controller 87 determines whether or not the electrostatic mist generator 43 has been removed. When it is determined that the electrostatic mist generating device 43 has been removed (YES in step S48), the control unit 87 cannot perform normal operation, and thus turns off the blower 44 in step S39 (FIG. 20). Further, the control unit 87 turns off the sterilization operation lamp 56. Thereafter, the process proceeds to an electrostatic mist generator installation notification process (FIG. 22).

  On the other hand, the controller 87 determines that the electrostatic mist generator 43 has not been removed (NO in step S48). In step S49, whether or not an operation for setting the drying operation time with the drying time setting button 53a has been performed. Judgment is made. When it is determined that the operation of the drying time setting button 53a has been performed (YES in Step S49), the control unit 87 turns off the sterilization operation lamp 56 in Step S41 (FIG. 13). Thereafter, the process proceeds to the operation time setting step S20 of the drying operation process (FIG. 12).

  When it is determined that the operation of the drying time setting button 53a has not been performed (NO in step S49), the control unit 87 starts the cooling operation in step S50 (the heater 45 and the electrostatic mist generator 43 are turned off). From) It is determined whether or not a predetermined time T4 has elapsed. The predetermined time T4 is a preset time for determining the end of the cooling operation (10 minutes in FIG. 17). When it is determined that the time T4 has not elapsed since the start of the cooling operation (NO in step S50), the control unit 87 returns to step S48.

  On the other hand, when it is determined that the time T4 has elapsed, the control unit 87 stores the current driving course in the memory 89 in step S51. Thereafter, the process returns to the standby step S2 of the power ON post-process (FIG. 18), and the drying / sterilization operation course ends.

  FIG. 22 is a flowchart illustrating electrostatic mist generating device installation notification processing executed by the tableware dryer according to the embodiment of the present invention.

  In step S61, the control unit 87 causes the water supply confirmation lamp 54 to blink. When the control unit 87 determines that the electrostatic mist generation device 43 is not installed based on the detection by the electrostatic mist generation device detection switch 108, the user is caused to blink the sterilization operation lamp 56 of the operation unit 19, for example. Notify As a result, the user can easily visually confirm that the drying / sterilization operation course cannot be performed. The case where the electrostatic mist generating device 43 is not installed includes the case where the drawer 41 in which the electrostatic mist generating device 43 is not stored is inserted into the main body, or the case where the drawer 41 itself is not inserted. The blinking of the water supply confirmation lamp 54 may be started in a state where the power is supplied, and not only after the on / off button 51 is turned on as described above, but also when the power is turned on, the electrostatic mist Blinking may be started according to the installation state of the generator 43 (steps S1 and S4).

  In step S62, it is determined whether or not the electrostatic mist generator 43 has been installed after being removed. If it is determined that the controller 87 is not installed after the electrostatic mist generator 43 is removed (NO in step S62), a predetermined time T5 (for example, 10 minutes) from the blinking of the water supply confirmation lamp 54 in step S63. It is determined whether or not elapses. The predetermined time T5 is for determining whether or not the notification need not be continued any more, such as when the user is away from the place. When it is determined that the time T5 has not elapsed (NO in step S63), the control unit 87 returns to step S62.

  When it is determined that the controller 87 is installed after the electrostatic mist generator 43 is removed (YES in step S62), and when it is determined that the time T5 has elapsed (YES in step S63), the power supply ON post-process Returning to the standby step S2 of FIG. 18, the blinking of the water supply confirmation lamp 54 is turned off.

  Although not particularly shown in FIGS. 18 to 22, the controller 87 detects whether the on / off button 51 is turned off at any step when the on / off button 51 is in the ON state in step 3. Even when the drying operation course or the sterilization / drying operation course is in operation, if the ON / OFF button 51 is turned OFF, the process returns to the standby step S2 of the power ON post-processing (FIG. 18). It has become.

  FIG. 23 is a flowchart for explaining power supply / cutoff control of the electrostatic mist generating device when the lid of the tableware dryer according to the embodiment of the present invention is opened and closed.

  As shown in FIG. 23, the tableware dryer 1 includes an electrostatic mist generator 43 that stops the generation of electrostatic mist when the open / close detector 16 detects the open state of the lid 11. Specifically, when the lid 11 is in a closed state (YES in step S70), the tableware dryer 1 is in a state where power can be supplied by connecting the electrical circuit of the control unit 87 and the high voltage power source 92. (Step S71). On the other hand, when the lid 11 is in the opened state (NO in step S70), the tableware dryer 1 blocks the electric circuit between the control unit 87 and the high voltage power source 92 (step S72).

  The open / close detection unit 16 (more specifically, the micro switch 76) performs this control regardless of the ON / OFF control of the electrostatic mist generator in the control unit 87. In other words, the open / close detection unit 16 is configured to cover the lid even if the electrostatic mist generator 43 is turned on (step S43 to step S46 in FIG. 21) or the electrostatic mist generator 43 is turned off (in other cases). If the body 11 is opened, the electric circuit between the control unit 87 and the high voltage power source 92 is cut off, and the electrostatic mist generator 43 is turned off. The open / close detection unit 16 connects the electrical circuit between the control unit 87 and the high voltage power source 92 when the lid 11 is closed even if the electrical circuit between the control unit 87 and the high voltage power source 92 is once interrupted. Since the power supply is enabled, the control unit 87 is executing the sterilization operation process (FIGS. 13 and 14), particularly during the ON control of the electrostatic mist generator 43 (step S43 to step S46 in FIG. 21). When the lid 11 is closed, the electrostatic mist generator 43 is turned on again.

  24 and 25 are side views showing other examples of the open / close detection unit of the tableware dryer according to the embodiment of the present invention.

  24 shows a state where the lid 11 is closed, and FIG. 25 shows a state where the lid 11 is opened.

As shown in FIG. 24, the open / close detection unit 16A of the tableware dryer 1A includes a magnetic sensor 115 that detects the open / closed state of the lid 11 from a change in the magnetic field accompanying the movement of the action unit 71A.
The action portion 71A is provided on the journal bearing portion 63 of the hinge 15 and moves together with the front cover 11b (turns around the rotation axis of the hinge 15).
The magnetic sensor 115 is configured using a so-called Hall IC (Integrated Circuit).
The open / close detection unit 16A of the tableware dryer 1A configured in this way detects the magnetic field of the action unit 71A moving together with the lid 11 by the magnetic sensor 115, and opens and closes the electric circuit between the control unit 87 and the high voltage power source 92. Let

  In this embodiment, the tableware dryer 1 which mainly has the function to dry dried materials, such as tableware, was demonstrated. However, you may apply this invention to the tableware dryer with a washing function provided with the function which wash | cleans tableware. Further, in the present embodiment, the control by the control unit 87 is not interposed between the opening and closing of the lid 11 and the power shutoff process of the electrostatic mist generator 43, so that the electrostatic mist generator when the lid 11 is opened. Although the structure which does not mechanically turn ON 43 was demonstrated, the detection result of the opening / closing state of the cover body 11 is input into the control part 87, and besides the electrostatic mist generator 43, the heater 45, the motor 44a, the fan 44b, You may make it control electric components, such as each lamp 55-56 and the timer 88. FIG.

  According to the tableware dryer 1 according to the present embodiment, it is not necessary to press the opening / closing detection unit 16 that turns on / off the electrostatic mist generating device 43 in conjunction with opening / closing of the lid 11 at the edge of the lid 11. . Accordingly, the tableware dryer 1 according to the present embodiment prevents erroneous detection of the open / close detection unit 16 due to the displacement of the combination of the main body 10 and the lid body 11. Further, the opening / closing detection unit 16 can adjust the width of play related to the detection of opening / closing of the lid 11 by appropriately adjusting the shape of the action part 71 or appropriately adjusting the attachment position of the action part 71A. Furthermore, since the open / close detection unit 16 is configured to extend from the hinge 15 to the inside of the main body 10 below the hinge 15, the possibility of breakage due to an unexpected contact between a user and an object to be dried is extremely low.

  Moreover, according to the tableware dryer 1 which concerns on this embodiment, even if it is in disinfection operation, if the cover body 11 is opened, the electrostatic mist generator 43 will be turned off immediately, and metal tableware etc. Therefore, even if the user opens the lid 11 unexpectedly, discomfort to the user can be suppressed without causing static electricity discharge.

  Therefore, according to the tableware dryer 1 which concerns on this embodiment, while opening / closing of the cover body 11 can be detected reliably, it is hard to produce the user and a to-be-dried object's unexpected contact, and the opening / closing detection with respect to the closing condition of the cover body 11 is detected. Play can be set appropriately.
