  As described above, the processing circuit can realize the function of the control device 50 by hardware, software, firmware, or a combination thereof.

  As an example, the operation of the dishwasher 1a is controlled by a single control device 50. The operation of the dishwashing apparatus 1a may be controlled by a plurality of linked apparatuses. The dishwasher 1a may include a plurality of devices as control means. The tableware washing apparatus 1a may include a plurality of processing circuits for realizing the function of the control means.

  Next, operation | movement of the tableware washing apparatus 1a is demonstrated. It is assumed that the separation mechanism 17, the electromagnetic valve 18a, the electromagnetic valve 18b, the electromagnetic valve 19a, and the electromagnetic valve 20a are closed during normal times when the dishwasher 1a is not operating.

  First, the user places an object to be cleaned such as the tableware 100 in the tableware basket 11. Then, the user puts the detergent into the cleaning tank 10. The detergent is, for example, dedicated for the dishwasher 1a. The detergent is stored at the bottom of the washing tank 10. The user who puts the detergent in the washing tank 10 operates the operation unit 51 to start the operation of the dishwashing apparatus 1a. FIG. 5 is a flowchart showing an operation example of the tableware washing apparatus 1a of the first embodiment. Hereinafter, the operation of the dishwasher 1a will be described with reference to the flowchart of FIG.

  When an operation for starting the operation is performed by the user, the control device 50 opens the electromagnetic valve 19 a and drives the pump 13. Thereby, water is supplied into the cleaning tank 10 through the water supply pipe 19, the pump 13, the water supply pipe 14, and the cleaning nozzle 12. At the bottom of the cleaning tank 10, water and detergent are mixed to become cleaning water. The cleaning water is stored at the bottom of the cleaning tank 10. Water is supplied to the cleaning tank 10 for a predetermined time. A predetermined amount of water set in advance is supplied to the cleaning tank 10. The above-described process of supplying water to the cleaning tank 10 is referred to as a first water supply process (step S101).

  When a specified amount of water is supplied to the cleaning tank 10, the control device 50 closes the electromagnetic valve 19a. Thereby, a 1st water supply process is complete | finished. After the first water supply step is completed, the control device 50 opens the separation mechanism 17, the electromagnetic valve 18a, and the electromagnetic valve 18b, and drives the pump 13. Accordingly, the cleaning water circulates through the cleaning tank 10, the residue collection container 15, the filter 16, the circulation pipe 18, the pump 13, the water supply pipe 14, and the cleaning nozzle 12. Further, the cleaning nozzle 12 ejects cleaning water toward the tableware 100. Thereby, the tableware 100 is washed. The above-described process of cleaning the tableware 100 with the cleaning water is referred to as a cleaning process (step S102).

  As described above, the separation mechanism 17 is open in the cleaning process. During the washing process, the washing water circulates through the washing tank 10, the residue collection container 15, the filter 16, the circulation pipe 18, the pump 13, the water supply pipe 14 and the washing nozzle 12. The residue contained in the circulating wash water is collected by the residue collection container 15 and the filter 16. Accordingly, the cleaning water from which the residue has been removed is supplied to the cleaning nozzle 12. In the cleaning process, the cleaning nozzle 12 ejects the cleaning water from which the residue has been removed toward the tableware 100.

  The cleaning process is executed for a predetermined time. The control device 50 stops the pump 13 after a certain time has elapsed since the start of the cleaning process. Thereby, the cleaning process is completed. After the cleaning process is completed, the control device 50 opens the electromagnetic valve 20a. When the electromagnetic valve 20a is opened, the washing water in the tableware washing apparatus 1a is discharged to the outside through the drain pipe 20. The above-described process of discharging the washing water to the outside of the tableware washing apparatus 1a is referred to as a first draining process (Step S103).

  Also in the first drainage process, the residue contained in the cleaning water is collected by the residue collection container 15 and the filter 16 as in the cleaning process. Thereby, in the 1st drainage process, the wash water in the state where the residue was removed is discharged. When the discharge of the cleaning water is completed, the control device 50 closes the electromagnetic valve 18a, the electromagnetic valve 18b, and the electromagnetic valve 20a. Thereby, a 1st drainage process is complete | finished.

  After the first drainage process is completed, the control device 50 opens the electromagnetic valve 19a and drives the pump 13. Thereby, a 2nd water supply process is performed (step S104). The second water supply process is the same process as the first water supply process. In the second water supply step, water for rinsing the tableware 100 cleaned with the cleaning water, that is, rinse water is supplied to the bottom of the cleaning tank 10. A predetermined amount of rinsing water is stored in the cleaning tank 10.

  The control device 50 closes the electromagnetic valve 19a when a predetermined amount of rinse water is accumulated in the cleaning tank 10. Thereby, a 2nd water supply process is complete | finished. After the 2nd water supply process is complete | finished, the control apparatus 50 opens the isolation | separation mechanism 17, the solenoid valve 18a, and the solenoid valve 18b, and drives the pump 13. FIG. As a result, the rinse water circulates through the cleaning tank 10, the residue collection container 15, the filter 16, the circulation pipe 18, the pump 13, the water supply pipe 14, and the cleaning nozzle 12. The washing nozzle 12 ejects rinsing water toward the tableware 100. The tableware 100 washed with washing water is rinsed with rinsing water. The above-described process of rinsing the tableware 100 with rinsing water is referred to as a rinsing process (step S105).

  In the rinsing process, the separation mechanism 17 is open. During the rinsing process, the rinsing water circulates through the washing tank 10, the residue collection container 15, the filter 16, the circulation pipe 18, the pump 13, the water supply pipe 14 and the washing nozzle 12. The residue contained in the circulating rinse water is collected by the residue collection container 15 and the filter 16. As a result, the rinsing water with the residue removed is supplied to the cleaning nozzle 12. In the rinsing process, the cleaning nozzle 12 ejects the rinsing water from which the residue has been removed toward the tableware 100.

  The rinsing process is executed for a predetermined time. The control device 50 stops the pump 13 after a certain time has elapsed since the start of the rinsing process. Thereby, a rinse process is complete | finished. After the rinsing process is completed, the control device 50 opens the electromagnetic valve 20a. When the electromagnetic valve 20a is opened, the rinsing water in the tableware washing apparatus 1a is discharged to the outside through the drain pipe 20. The above-described process of discharging the rinse water to the outside of the tableware washing apparatus 1a is referred to as a second drainage process (Step S106).

  After the rinsing process is completed, the control device 50 closes the separation mechanism 17. Thereby, a drying process is started (step S107). The drying step is a step for drying the tableware 100 that has been cleaned and rinsed. In the drying process, no liquid is supplied to the cleaning tank 10 that houses the tableware 100. Thereby, the tableware 100 dries. The drying process is executed for a predetermined time. When the drying process is performed for a certain period of time, the dishwasher 1a ends the operation.

  After the drying process of the above embodiment is completed, for example, the user takes out the tableware 100 from the cleaning tank. The user who has taken out the tableware 100 removes the residue collection container 15 and the filter 16 from the cleaning tank 10. The user discards the residue repaired in the residue collection container 15 and the filter 16 and cleans the residue collection container 15 and the filter 16.

  Here, the residue collection container 15 and the filter 16 may be formed of a material that can be washed by the tableware washing apparatus 1a. Moreover, the tableware washing apparatus 1a may be provided with the residue collection container 15 and the two filters 16. FIG. For example, the user may wash another set of the residue collection container 15 and the filter 16 with the dishwasher 1a in a state where the set of the residue collection container 15 and the filter 16 are installed below the washing tank 10.

  In steps S101 to S107 described above, the control device 50 operates based on, for example, a program stored in advance in the control device 50. Thereby, each process of step S101 to step S107 is performed. Further, as an example, the control device 50 measures an elapsed time after the operation unit 51 is operated by the user before step S101. The control device 50 executes various processes from step S101 to step S107 based on the measured elapsed time.

  In addition, the flowchart shown in FIG. 5 shows an example of operation | movement of the tableware washing apparatus 1a. For example, the timing of a 1st water supply process, a 1st drainage process, a 2nd water supply process, and a 2nd drainage process is not restricted to the example shown in FIG. For example, each process of step S101 to step S103 may be repeated twice or more. Similarly, each process from step S104 to step S107 may be repeated twice or more.

  In the drying process of the above-described embodiment, the separation mechanism 17 is closed. In the drying process, the space inside the cleaning tank 10 is separated from the space inside the residue collection container 15. That is, the space where the washed tableware 100 is located is separated from the space where the residue is collected. If the dishwashing apparatus 1a includes the separation mechanism 17 capable of separating the inside of the washing tank 10 and the inside of the residue collection container 15, for example, it is possible to prevent the smell of the residue from being transferred to the washed dishware 100.

  Moreover, the tableware washing apparatus 1a may be provided with the heating apparatus as an apparatus which dries the tableware 100 more efficiently in a drying process, for example. The heating device is a device that raises the temperature of the inside of the cleaning tank 10. The heating device may be a device that blows out hot air, for example.

  If the tableware washing apparatus 1a of the above-described embodiment is capable of separating the inside of the residue collection container 15 from the inside of the washing tank 10, the residue collected in the residue collection container 15 and the filter 16 is heated by the above heating device. Is prevented. Thereby, even when raising the temperature of the inside of the washing tank 10 in the drying step, no odor is generated from the residue collected in the residue collection container 15 and the filter 16.

  The tableware washing apparatus 1a may include, for example, a heater (not shown) that heats washing water and rinsing water. The dishwasher 1a may be able to use cold water and hot water separately.

  In the above embodiment, the separation mechanism 17 is controlled by the control device 50. In other words, in the above embodiment, the separation mechanism 17 operates electrically. The separation mechanism 17 may be mechanically operated. The separation mechanism 17 may be a mechanism that mechanically opens by receiving a load from water and residue, for example. In addition, the separation mechanism 17 may include a sensor that detects the weight of water, residue, etc. on the separation mechanism 17, for example. The separation mechanism 17 may be a mechanism that opens when the weight detected by the sensor is equal to or greater than a certain value.

As described above, in the present embodiment, the object to be cleaned by the pre-washing booth 30 is automatically cleaned.

  Here, the process of cleaning the objects to be cleaned by the prewash booth 30 is referred to as a prewash process. In the present embodiment, in the pre-washing process, first, water is jetted from the water nozzle 42. As a result, large residues and liquid dirt adhering to the object to be cleaned are removed by water. If it is this Embodiment, the dish washing apparatus 1c which can wash | clean the to-be-washed | cleaned object before inserting in the washing tank 10 previously with water is obtained. The water jet from the water nozzle 42 is performed for a certain time.

  After the injection of water from the water nozzle 42 is completed, the foam is discharged from the foam nozzle 43. As a result, oil stains that are difficult to wash away with water are removed from the object to be cleaned by foam. If it is this Embodiment, the dish washing apparatus 1c which can wash | clean the oil stains etc. which adhered to the to-be-cleaned object before being inserted in the washing tank 10 previously with foam is obtained. Foam discharge from the foam nozzle 43 is performed for a certain period of time.

  After the foam discharge from the foam nozzle 43 is completed, water is again sprayed from the water nozzle 42 for a certain period of time. As a result, dirt and foam remaining on the object to be cleaned are washed away with water. After the water injection from the water nozzle 42 is completed, air blows out from the wind nozzle 41. The air blown out from the wind nozzle 41 hits an object to be cleaned in the prewash tank 31. Thereby, water, residue, etc. adhering to the object to be cleaned are blown away. If it is this Embodiment, the tableware washing apparatus 1c which can remove the water, residue, etc. which adhered to the to-be-cleaned object before inserting in the washing tank 10 with a wind is obtained.

  Air is blown out from the wind nozzle 41 for a certain period of time. The pre-washing process ends when the blowing of air by the wind nozzle 41 ends. In the pre-washing process, it is not necessary to completely remove residues, water, etc. adhering to the object to be cleaned. After the pre-washing process is completed, the user moves an object to be cleaned such as tableware 100 from the pre-washing tank 31 to the washing tank 10. The objects to be cleaned such as the tableware 100 transferred to the cleaning tank 10 are cleaned with cleaning water and rinsing water.
