If the starting point on the inclined plane at the back side of the filter housings of pulling out 52 arrives near near the open upper end portion (perhaps the peristome of top plate portion) that filter places portion 25; Then shown in Fig. 9 (b), to top pull-up Soft flocks filter element 32 on one side to front sideway swivel pull out (arrow D direction) on one side.

The operation that this goes out to the front layback; Operation compared with direct pull-up straight up; Can easily operate, that is, the user the eminence of top plate portion 1b further to above the operation of the pull-up difficulty that becomes gradually; With respect to this, can easily carry out with the operation that pull out to the mode of front sideway swivel on the inclined plane at the back side that utilizes Soft flocks filter element 32.

Then, Fig. 9 (c) expression to the top, front pull out Soft flocks filter element 32 (arrow E direction), with its state that takes out fully from outer container 1.Therefore, the Soft flocks filter element 32 (for example with reference to Fig. 7 (a)) of the state that will take out from scrubbing-and-drying unit moves to predetermined location, shown in Fig. 7 (b), opens cap 53, removes the Soft flocks of being caught in the filter housings 52 and also clears up lint filter 51.

In addition, when in scrubbing-and-drying unit, being mounted to original position, carry out, thereby be inserted into and fixing branch is held in the precalculated position of top wind path 21 according to the order opposite with above-mentioned taking-up operating sequence at the Soft flocks filter element 32 that will finish cleaning.Also can unlike shown in Fig. 9 (b), (c) with Soft flocks filter element 32 to the front top rotation pull out but the then operation shown in Fig. 9 (a) and directly pulling out along direction straight up.

Then, with reference to Figure 10 and Figure 11 the main part of scrubbing-and-drying unit shown in Figure 1 is described with the mechanism for installing that places the outer container 1 of this main part.

Lint filter places each parts of the upper pipe 22 of portion 25, circulation wind path 20 and the portion 40 that hangs down, rising portions 42, heat exchanger 43, pressure fan 44, heater housing 47, is fixed on outer container 1 side of the gabarit that forms main part.

Said filter places portion 25, through joint and the screw element 252 based on hook-like assembly unit 251, is fixed in the reinforced bulkhead 253 of the top plate portion 1b that is arranged at outer container 1.

Said reinforced bulkhead 253 is set up between the upper end-face edge of biside plate 1c of outer container 1, and utilizing enough, the intensity of reinforcement outer container 1 can stably keep filter to place portion 25.

And; The upper opening of portion 40 hangs down; Thereby it is chimeric and adhere to the connector 39 that is fixed in said lower pipeline 23 through screw element and be engaged in top wind path 21; Make the stationary hub (boss) 231 that is arranged at upper pipe 22 be engaged in that rising wood at side plate 1c spreads all over fore-and-aft direction and the back side of the flange part that forms is fixed through screw element 232, thereby is fixed in outer container 1 side.

In addition, pressure fan 44 screw threads are fixed in and are arranged at the stationary hub 221 of upper surface that said filter places the upper pipe 22 of portion 25.Heater housing 47 through screw element 254 adhere to the backside openings that is fixed in main body be located between the biside plate 1c in the upper shelf of the backboard 1d of said outer container 1, to the stiffener 220 that outer container 1 is strengthened, this heater housing 47 makes blower-casting 45 integrated as parts and this pressure fan 44.
