  Embodiments of the present invention will be described below with reference to FIGS.

(Embodiment 1)
As shown in FIGS. 1 and 2, the tableware dryer according to Embodiment 1 of the present invention is provided with a hot air generator 3 that houses a blower 1 as a blowing means and a heater 2 as a heating means at the rear upper part. The main body 5 whose upper surface is covered with the water tray 4, the tableware basket 6 that stores the washed dishes and the like and is placed on the water tray 4 of the main body 5, and the upper part of the main body 5, that is, the tableware basket 6 and a lid 7 covering 6. The lid 7 is divided and connected to a front lid 7a, an inner lid 7b, and a rear lid 7c. The lid 7 covers the upper part of the main body 5 so as to be openable and closable. It is formed as a drying chamber 8 into which warm air is blown.

  Further, the air blown from the blower 1 into the drying chamber 8 returns to the blower 1 through the inside of the main body 5 (air path is not shown), and is again blown from the blower 1 into the drying chamber 8 to circulate. It is said.

  Further, an electrostatic atomizing means 10 is disposed in a discharge air passage 9 that discharges from the blower 1 through the heater 2 to the drying chamber 8. As shown in FIG. 3, the electrostatic atomizing means 10 includes a discharge electrode 10a to which a high voltage is applied, a counter electrode 10b provided to face the discharge electrode 10a, a cooling unit 10c, and a heat dissipation unit 10d. When the DC power is supplied to the heat exchanging unit 10e, the heat exchange occurs in the heat exchanging unit 10e, the temperature of the cooling unit 10c decreases, and the moved heat is transferred from the heat radiating unit 10d. When the heat is dissipated and the air is cooled in the cooling unit 10c in this process, the condensed water adheres to the discharge electrode 10a provided integrally with the cooling unit 10c, and a high voltage is applied to the discharge electrode 10a to cause discharge. Charged fine water droplets, which are ultrafine particle ions wrapped in water, are generated, and the charged fine water droplets are disposed so as to be discharged into the drying chamber 8 by blowing air from the blower 1.

  The tableware dryer is provided with an operation unit 11 for operating the front of the main body 5.

  As shown in FIG. 4, the operation unit 11 includes an operation on / off switch 14 for starting and stopping operation, an operation switching switch 12 for switching operation in a hot air drying mode described below, A standard lamp 12A that is turned on when the operation changeover switch 12 is used to switch to a drying operation of a standard quantity of tableware that is dried by warm air. When the amount of tableware to be dried is smaller than the standard amount, a small lamp 12B that is turned on when switching to the drying operation, and when the tableware is to be cooled and taken out in summer, etc., the heater 2 is stopped after the hot air blowing operation Then, the air blowing finish lamp 12C that is turned on when the operation is switched to the air blowing finishing operation for performing only the air blowing, and each operation in the warm air drying mode for drying the tableware and the like. Engagement without and a ion switch 13 for operating the electrostatically atomizing air blowing mode for generating a charged fine water droplets from the electrostatic atomizing unit 10 alone.

  Next, the operation of the tableware dryer having the above configuration will be described.

  When drying a standard amount of tableware or the like washed outside the summer, the operation is started by the operation on / off switch 14 of the operation unit 11, and the operation switch 12 is repeatedly pressed until the standard lamp 12A is lit.

  Then, as shown in FIG. 5, when the operation is started, the blower 1 and the heater 2 are energized, and hot air is blown for a time Th1 (= Tfd1) set in advance as a time for drying the dishes and the like. And when time Th1 passes, electricity supply to the heater 2 will stop and it will drive | operate only the air blower 1. FIG. At this time, the tableware and the like are in a dry state.

  On the other hand, the electrostatic atomizing means 10 starts to operate after a predetermined time T2 has elapsed from the time when only the blower 1 is operated.

  Then, the electrostatic atomizing means 10 operates for a predetermined time T1 (= Tf1) and stops simultaneously with the blower 1.

  Here, for the predetermined time T2, after the heater 2 is stopped and only the blower 1 is operated, the temperature of the discharge air passage 9 is lowered, and the heat radiation in the heat radiating portion of the electrostatic atomizing means 10 is improved. This time is set in advance as the time until the part cools and the dew electrode is condensed, and the charged fine water droplets are stably generated, and is shorter than the time Th1 when the hot air is blown. It is set longer than the predetermined time T1 of the electroatomizing means 10.

  That is, most of the bacteria in the drying chamber 8 are sterilized when the tableware is dried by warm air before the operation of the electrostatic atomizing means 10, and the charged fine water droplets are ultrafine. In addition, the charged fine water droplets are wrapped in water and have a longer life than general air ions, and are supplied by circulating air. The time T1 can be made shorter than the predetermined time T2 of the blower 1 alone, and further, the air volume of the blower 1 at the time of operation can be made smaller than the hot air blow volume at the time of drying the dishes.

  Thus, even if the operation time of the electrostatic atomizing means 10 is shorter than that of the tableware drying operation by hot air blowing, and there are a lot of tableware to be dried, the intended charging is performed. It is possible to achieve sterilization or neutralization of bacteria and viruses with fine water droplets.

  Next, the blast finishing operation will be described.

  When it is felt that it is more comfortable to use the tableware when it is used in summer, etc., when the operation changeover switch 12 of the operation unit 11 is pressed to turn on the blast finish lamp 12C, the blast finish operation is started.

  As shown in FIG. 6, when the operation is started, the blower 1 and the heater 2 are energized to blow warm air for a time Th2 (= Tfd2) set in advance as time for drying the tableware in summer. And if time Th2 passes, electricity supply to the heater 2 will stop and it will become the cooling ventilation operation of only the air blower 1 in order to cool tableware.

  On the other hand, a temperature sensor (not shown) is disposed in the discharge air passage 9, and after the heater 2 is stopped, the cooling air blowing operation is performed and the temperature of the discharge air passage 9 is lowered, and the electrostatic atomizing means 10. When the temperature sensor detects a predetermined temperature set as a temperature at which heat dissipation in the heat dissipation part becomes good (time Ts2 has elapsed), the electrostatic atomizing means 10 is activated.

  Then, the electrostatic atomizing means 10 is operated together with the blower 1 for a predetermined time T3 set as a time during which bacteria or viruses in the drying chamber 8 can be sterilized or neutralized, and the dishes are cooled. First, the time Tc operation is performed as the cooling air blowing operation.

  Thus, in the air blow finishing operation, it is not necessary to provide the operation time of the electrostatic atomizing means 10 separately from the original tableware drying operation, and only the blower 1 until the electrostatic atomizing means 10 is operated. Can be performed with high accuracy based on the actual temperature of the discharge air passage 9 by the temperature sensor, and the operation time of the electrostatic atomizing means 10 is set as a time that can be achieved as expected. Since it is set as time T3, while being able to drive | operate more efficiently, a burden is not added to a user.

  In addition, the hot air drying mode in which a small lamp 12B is turned on when drying a small tableware, etc., has a point that the operation time of the hot air blowing is shorter than the drying operation of the above-mentioned standard amount of tableware. The only difference is the other steps.

  Next, an electrostatic atomizing air blowing mode in which charged fine water droplets are generated from the electrostatic atomizing means 10 regardless of the above-described operations in the temperature drying mode will be described.

  In this electrostatic atomizing air blowing mode, the lamp 13A with tableware and the lamp 13B without tableware are alternately turned on by pressing the ion switch 13 shown in FIG. 4, and when there is tableware in the tableware basket 6 and there is no tableware. There is a driving to display the case.

  The operation with and without tableware is not shown in the figure, but the operation time is set in advance by setting the table time with time T4-1 longer than the time without tableware T4-2.

  In addition, intermittent operation is performed during operation.

  And if you feel uneasy about energizing the heater 2 in the absence of a person, such as when you go out immediately after washing the tableware and operate the tableware dryer at your home, you can dry the tableware for a while. Only when the electrostatic atomization means 10 and the blower 1 are operated, for example, when it is desired to clean the inside before starting to use again without using the machine.

  In this way, it is possible to generate charged fine water droplets by specifying to disinfect the inside of the drying chamber 8 and to neutralize the virus, and it is possible to select an appropriate operation time depending on the object, Since the charged fine water droplets exist without disappearing for a certain period of time, even if the electrostatic atomizing means 10 is intermittently operated, the operation effect is not affected and an efficient operation can be performed.

(Embodiment 2)
The tableware dryer according to the second embodiment of the present invention is preliminarily determined from the time when the tableware dryer according to the first embodiment stops the energization of the heater 2 and only the blower 1 is operated in the tableware drying except summer. The electrostatic atomizing means is operated after the set second predetermined time T2 has elapsed. On the other hand, a temperature sensor (not shown) is provided in the discharge air passage 9, and the discharge air is discharged after the heater 2 is stopped. When the temperature sensor detects a predetermined temperature set as a temperature at which the temperature of the passage 9 decreases and the heat radiation of the heat radiation portion becomes good (at the time Ts1 in FIG. 7 has elapsed), the electrostatic atomizing means 10 is activated. Is different.

  With this configuration, the operation of only the blower 1 until the electrostatic atomizing means 10 is operated is performed by detecting the actual temperature of the discharge air passage 9, so that the operation can be performed with high accuracy and efficiency. .

  The tableware dryer according to the present invention stably generates ultra-fine charged fine water droplets, flows into the narrow gaps between the tableware, puts a lot of tableware, and may adhere to bacteria and viruses. However, it is useful as a tableware dryer that can sterilize or neutralize viruses without any problem and can always dry clean dishes.
