Problems solved by technology
[0007] The existing screen cleaning device utilizes the suction effect generated by the negative pressure to attract and remove the dust caught by the screen. With control device for start and stop
In addition, there is only a very small gap between the suction duct that attracts dust and the air inflow surface of the screen, and since air flows in through this gap, it is necessary to increase the capacity of the negative pressure generating blower accordingly. There is a problem that the negative pressure in the suction catheter decreases (pressure increases), and the efficiency deteriorates

Embodiment Construction
[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 is the front view of the device. figure 2 It is a plan view showing the suction port of drying air, image 3 is a transverse cross-sectional view of the center of the suction catheter.
[0022] exist figure 1 Among them, 1 is a casing with a tank (drying chamber) formed inside, and a door 2 is provided in the center, and the door 2 is used for inputting and discharging laundry. 3 indicated by a dotted line is a drum for putting in laundry and rotating it. On the upper surface of the casing 1, a heater 4 using steam as a heat source is provided, and the upper surface becomes an air inlet 5 for drying. From the suction port 5, through the heater 4, the drying air flowing into the housing 1 is turned back by the damper provided in the housing 1, and exhausted from the exhaust port 6 with the built-in exhaust fan. In the suction port 5, a flat dustproof screen ...

The present invention relates to a device for drying washings by allowing the heated air for drying to pass through the groove. The screen sweeping apparatus of the device is used for removing the dust captured by the dustproof screen arranged on the suction entrance of the air for drying. The present invention can reduce the equipment cost and the operating cost of the screen sweeping apparatus,and can clean the dustproof screen more efficiently using a device with more simple structure. The dryer for washings comprises a suction vessel(8)for attracting and removing the dust captured by thedustproof screen in good time; and an equipment operated by air pressure. The dryer for washings further comprises a switching valve(11)arranged on the supplying pipe(9)of the air pressure; a negativepressure generator(13)using the jet flow of the air pressure switched by the switching valve; a negative pressure pipe(17)communicating the negative pressure generated by the negative pressure generator to the suction vessel and switching the switching valve when the dryer is stopped so as to attract and remove the dust captured by the dustproof screen.
Description
technical field [0001] The present invention relates to a device for drying laundry by passing heated drying air through a tank, and more particularly, to the above-mentioned device characterized in that it periodically removes the dust-proof material provided on the drying air suction port. The dust in the air captured by the screen (mainly wind cotton). Background technique [0002] The laundry dryer widely used in commercial washing equipment is equipped with a cylindrical drum that rotates around a horizontal axis in the tank, and the laundry is put into the drum, while the drum is slowly rotated, and the drying air is blown horizontally. Pass the way through the drum. The laundry in the drum is lifted by the rotation of the drum, then falls from above, and is lifted again with the rotation of the drum. This operation is repeated, and the drying air passing through the drum is dried during this period. The air for drying is usually sucked into the air in the workshop f...
