Stopping degree sensing method of gauze filter

Abstract

A method for sensing the blocked degree of gauze filter features that during baking job, the rotation speed (RPM) of variable exhaust blower is monitored, and when said rotation speed is higher than a reference value to some extent the blocked degree of gauze filter and exhaust pipe can be sensed and a signal is sent to user for scavenging them.

Description

technical field [0001] The invention belongs to a drying machine, and in particular relates to a method for sensing the clogging degree of a gauze filter. Background technique [0002] figure 1 It is an exploded oblique view of the main parts of the dryer in the prior art. As shown in the figure, a drum 1 is arranged inside the shell constituting the appearance of the dryer. The drum 1 is in the shape of a cylinder with both ends open, and a drum belt driven by a separate driving source is wound on a belt groove 2 formed in the middle of the outer peripheral surface of the drum 1 . A drying space 5 is formed inside the drum 1 . A plurality of baffles 6 are formed inside the drying space 5 , and the plurality of baffles turn over the drying objects in the drying space 5 when the drum 1 rotates. [0003] The front end and the rear end of the drum 1 are respectively provided with a front end cover 7 and a rear end cover 9 correspondingly. Wherein the front end cover 7 and ...

AI Technical Summary

Problems solved by technology

[0015] The above-mentioned prior art has the following problems: the air that absorbs moisture inside the drying space 5 is driven by the exhaust fan 17, passes through the outlet assembly 13 in the drying space 5, and then is sent to the gauze channel through the gauze filter 14 15

So a lot of foreign matters filtered by the gauze filter 14 make the air flowing from the drying space 5 to the gauze channel 15 unable to flow smoothly.

[0016] In the prior art, the extent to which the gauze filter 14 filters foreign matter, that is to say, the prior art cannot allow the user to easily confirm the clogging degree of the gauze filter 14, so that the dryer is almost blocked when the gauze filter 14 is blocked. still working

So the following problem occurred: the dryer works under the condition that the gauze filter 14 is blocked, so that the air flow through the drying space 5 cannot be smooth, and the normal drying effect cannot be achieved.

In addition, if the gauze filter 14 is clogged and the air flow is not smooth, the temperature inside the drum 1 will rise sharply.
