Cleaning and drying machine for tableware

Abstract

The present invention provides a tableware washing and drying machine in dry operation which can mix enough outer gas during a wash tank discharging gas for promoting temperature reduction of discharged gas and decreasing moisture in discharged gas, in which a drying device (9) having a vent (7) for discharging humidity inside of the wash tank (1), a blast engine (6) and a mixing device (13).The mixing device is mounted at the upstream side of the vent to mix outer gas from outside of the machine into the wash tank inner gas from the wash tank for cooling down inner gas of the wash tank. The wash tank inner gas channel (15) of the mixing device and outer gas channel (14) have rectangular section shapes with big aspect ratio respectively, and longer edging of the channels are connected each other for processing interflow.Outer gas flowing in the mixing device and inner gas of the wash tank can be mixed in minor space to cool down inner gas of the wash tank, thereby reducing air discharging humiture, preventing hot air feel reliably, implementing miniaturization of the device.

Description

technical field [0001] The invention relates to a tableware washing and drying machine for storing objects to be cleaned and performing automatic cleaning and drying operations arranged in a kitchen or the like. Background technique [0002] In the existing tableware washing and drying machine, in order to dry the object to be cleaned after cleaning, it is necessary to blast outside air into the cleaning tank to discharge the high-temperature and high-humidity air in the cleaning tank (for an example, refer to Japan Patent Laid-Open Gazette 2000-166847). [0003] Figure 4 The conventional dish washing and drying machine described in the said reference document is shown. Such as Figure 4 As shown, this existing tableware washing and drying machine is provided with: a cleaning tank 1 for storing objects to be cleaned; a cleaning nozzle 2 for spraying cleaning water and a cleaning pump 3 for pressurizing the cleaning water; Device 4; a heating device 5 for heating the clean...

AI Technical Summary

Problems solved by technology

[0004] However, if the above-mentioned existing structure is adopted, because the fluid force of the high-temperature and high-humidity main airflow flowing into the exhaust port makes the fresh outside air mixed into the exhaust gas as an auxiliary airflow, although it can be used to a certain extent The temperature of the exhaust gas in the high-temperature and high-humidity cleaning tank is lowered, but there is still a problem of insufficient air volume if the exhaust air flow is to be sufficiently cooled to avoid the feeling of hot air.
