Abstract

PURPOSE:To facilitate a removal of dust adhered to a filter by a method wherein a filter frame of a suction air filter is provided with some guide holes, both end carsors are slidably fitted to the guide holes and then a brush member is installed. CONSTITUTION:A suction filter 1 is arranged such that it may be entered into or retracted from a right side through four guides 7 arranged at a rear surface 3. A filter frame 5 is provided with some projections 8 for setting a position of a suction filter 1 when the suction filter 1 is inserted into the guides 7. A vertical outer circumferential surface is formed with some concave grooved guide holes 9. A surface of the suction filter 1 is provided with a brush body 10 having a brush 11 for use in dropping dust. This brush body 10 is provided with carsors 12 at its both ends which are slidably fitted to the guide holes 9. Accordingly, the brush body 10 can be slid in an upward or a downward direction with a handle 13 so as to cause the dust on the surface of the suction filter 1 to be fallen with the brush 11. In case that the suction filter 1 is to be washed, the suction filter can be pulled out along the guides 7 from a right side surface while keeping the brush body 10 in it.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for removing clumps, which is used in air purifiers such as gas hot air heaters, coolers, and hot air heaters.

BACKGROUND ART Conventionally, the structure of a filter provided in this type of air intake section is as shown in FIGS. 5 and 6. Intake filter 1
is attached to the rear surface 3 of the main body 2, takes in hot air from the intake filter 1, turns into warm air within the device, and then outputs it as warm air from the outlet 4. The intake filter 1 is integrated with a filter frame 5 and a mesh 6, and is configured such that a guide 7 is provided on the back surface 3 of the main body 2, and the intake filter 1 is guided by this guide 7 and pulled out upward. has been done.

Problems to be Solved by the Invention However, in the above configuration, the intake filter 1
Because more combustion air and hot air are taken in,
It inhales a large amount of indoor dust and dirt, and a large amount of dust accumulates in the intake filter 1, which adversely affects combustibility, or a large amount of dust accumulates, causing the equipment to stop working. This had the disadvantage that the filter 1 had to be removed from the device and cleaned.

The present invention solves the above problems and makes it possible to easily remove dust attached to a filter.

Means for Solving the Problems In order to solve the above-mentioned problems, the dust removal device of the present invention has a guide hole formed in the filter frame of the intake filter in a part where the guide to which the intake filter is detachably attached is not located. The brush body is provided with the cursor at both ends slidably fitted into the guide hole.

Function According to the above configuration, even if dust adheres to the intake filter, by moving the brush body up and down, the brush can remove the dust that has adhered to the intake filter.

EXAMPLE An example of the present invention will be described below based on the drawings. A main body 2 of the gas hot air heater has a hot air outlet 4 on the front side, and an intake filter 1 for filtering hot air and combustion air on the back side 3. This intake filter 1 is provided so that it can be entered and removed from the right side by means of four guides 7 provided on the back surface portion 3. Reference numeral 5 denotes a filter frame, which is provided with a protrusion 8 that abuts against the guide 7 to position the intake filter 1 when the intake filter 1 is inserted into the guide 7. Further, the filter frame 5 has a guide hole 9 in the form of a concave groove formed in the vertical outer shoulder portion. A brush body 10 having a brush 11 for removing dust is disposed below the intake filter 1. The brush body 10 is provided at both ends with a cursor 12 that is movably fitted into the guide hole 9. Therefore, the brush body 10 is slid up and down with the handle 13, and the brush 11 causes dust to fall from the intake filter 1. Note that when washing the intake filter 1, the pull-out can be removed from the right side along the guide 7 while the brush body 10 remains attached.

Effects of the Invention As described above, according to the present invention, dust is constantly removed from the intake filter by the brush body, so that the normal operation of the equipment can be protected, and since the brush body and the intake filter can be removed from the equipment, it is easy to attach and detach. Easy to operate.
