And, jut 42 also with above-mentioned other inner surface 40b, 40c, the 40d (inner surface of pipeline cover 37) that similarly is arranged on wind path 40, that is, jut 42 is arranged on the complete cycle of wind path 40.
On the other hand, branch road 41 by rib 43 and the rib 44 parallel with the top 43a of this rib 43 that separates with wind path 40, forms the path shape narrower than wind path 40, and the surface not have to form the parts suitable with above-mentioned jut 42 within it.
In addition, the upper end 41a of branch road 41 is set to roll tiltedly to wind path 40, and therefore, the top 43a of rib 43 and rib 44 roll tiltedly to wind path 40.Thus, change the flow direction by the air of wind path 40, make this air can directly not enter pressure fan 25.Thus, can make rolled-up water enter not at all pressure fan 25.
Wind path 40 by making its top 40e to stretching out and expand with the side of the opposite side of branch road 41 sides (section's 32 sides hang down), thereby has enlarged the wind path area of section on top.In the part that has enlarged this wind path area of section, namely from the top 40e that wind path 40 stretches out, also be formed with water filling section 45 in its outside.
This water filling section 45 comprises: the bellying 46 that further stretches out the hollow that bloats from the top 40e of above-mentioned wind path 40 to the side; Cover the shielding portion 47 of other parts outside the bottom of removing wind path 40 sides of this bellying 46; Water filling port 48 with the upper surface part 46a that is formed at bellying 46.In addition, the wall of water filling section 45 belows of rising portions 34 is inclined plane 49.
And, at water filling port 48, as shown in Figure 7, be externally connected with an end of water filling flexible pipe 50 at rising portions 34, the other end of water filling flexible pipe 50 is connected in the bifurcations (details are not shown) of described feed water valve 16, and this open during from drying bifurcations is supplied with running water via water filling flexible pipe 50.
In addition, be formed with the gas outlet 51 of the suction inlet that is connected in described pressure fan 25 at the topmost of rising portions 34.
In addition, express the rib 52,53,54 that forms with described jut 42 at the inner surface of pipeline cover 37 in Fig. 2, these all are embedded in respectively the major part of reflex part 33 and most circumference and the rib 43,44 of rising portions 34.
Next, the effect of the drum-type washing drying machine of above-mentioned formation described.
In the above-described configuration, in the absence that makes washings (diagram) drying that is captured in the cylinder 12, make cylinder 12 low speed rotation on positive and negative both direction by motor 15, drive simultaneously pressure fan 25 and make the electric heater heating of heater 28, and then make the bifurcations of feed water valve 16 open and supply water to the water filling section 45 (water filling port 48) of dehumidifier 39 via water filling flexible pipe 50 from bifurcations.
In addition, utilize the air-supply effect of pressure fan 25, repeatedly carry out with the air in the circulation wind path 17 from be blown into mouthfuls 11 be blown into the inside of the inside of water jacket 8 and cylinder 12 and with the air of the inside of the inside of cylinder 12 and water jacket 8 from the work that the blow-off outlet 10 of water jacket 8 blows out to circulation wind path 17, make thus the air of inside (inside of cylinder 12) of water jacket 8 by circulation wind path 17 circulate (with reference to the arrow A of Fig. 6).
Explanation wind this moment flows in further detail.Air in the circulation wind path 17 are by the heating of the electric heater of heater 28, and this air (warm braw) that has been heated is by flexible duct 30 and rear portion wind path 31, are supplied to the inside of water jacket 8 and the inside of cylinder 12 from being blown into mouthfuls 11.Be supplied to the warm braw of the inside of cylinder 12, the washings of the inside of cylinder 12 is heated, obtain moisture from this washings.
Obtained the warm braw of moisture from washings, blown out to circulation wind path 17 from blow-off outlet 10, through flexible duct 20, in top wind path 18, flowed towards the rear.When containing Soft flocks in the air that in this top wind path 18, flows, most being caught by lint filter unit 21 of this Soft flocks, the Soft flocks that passed through lint filter unit 21 lint filter that also is fixed is caught.
The flowed through warm braw of top wind path 18, dehumidifying with pipeline 24 in from above flow through downwards after the section of hanging down 32, become upward via reflex part 33, (with reference to the arrow A Fig. 1, Fig. 3, Fig. 4) upward flows from the below in the wind path 40 of dehumidifier 39 and branch road 41 (inside of rising portions 34).
At this moment, the outside of the opposition side of the origination side that turns back of wind path 40 (part of inner peripheral surface 40a), the air that the flow losses of air are little, enter wind path 40 from the origination side that turns back is easy to flow with the force and velocity of a current, and wind speed is high, and air quantity is also large.In addition, large in the origination side Air Flow loss of turning back on the contrary, air is difficult to flow, and wind speed is low.And, be formed at the wind path area of section enlarged of the top 40e of wind path 40, direction in the outside of the opposite side of the origination side that turns back has enlarged wind path 40, so the wind speed of the air by wind path 40 is reduced in the part near pressure fan 25, so can more effectively make rolling of injected water be difficult to occur.
In addition, at this moment, by in the future confessing that the water of the bifurcations of water valve 16 is supplied to water filling section 45, thereby from inside (wind path 40) water filling of 45 pairs of dehumidifiers 39 of water filling section.Be injected into the injected water of this wind path 40, shown in the arrow B of Fig. 1, Fig. 3 and Fig. 4, the inner peripheral surface 40a at the wind path 40 that links to each other with this inclined plane 49 from inclined plane 49 moves, and the limit disperses the limit to flow down by jut 42.
Here, inner circumferential surface 40a is the face of an opposite side of the origination side that turns back of above-mentioned wind path 40, also as mentioned above, also be from the air that the origination side that turns back enters wind path 40 be easy to the force and velocity of a current flow, wind speed is high and also large part of air quantity.
Therefore, air by wind path 40, with utilization be arranged on the part that air easily flows, wind speed is high and air quantity is large inner peripheral surface 40a jut 42 and the water that disperses contacts at most, therefore, the cooling that can carry out well the air by wind path 40 condense (dehumidifying).
In addition, owing to carrying out the water that the dehumidifying of the air by wind path 40 produces, the water that flows down with the inside at dehumidifier 39 accumulates in the inner bottom part that pipeline 24 is used in dehumidifying, and its water level is discharged to drainage channel via the drainpipe that is connected with water discharge outlet 38 after surpassing the height of water discharge outlet 38.
And the air of the wind path 40 of the dehumidifier 39 of flowing through after being inhaled into pressure fan 25, is sent to heater 28, there again by the heating of the electric heater of heater 28.The air that has been heated as previously mentioned, by flexible duct 30 and rear portion wind path 31, returns the inside of water jacket 8 and internally flowing of cylinder 12 from suction inlet 11.By air is circulated like this, come the washings of the inside of dry swing roller 12.
Like this, by in the circulation wind path 17 of the air circulation of the inside that makes the water jacket 8 that is equipped with cylinder 12, being provided with the formation of water-cooled dehumidifier 39, this dehumidifier 39 is become have in inside the structure that makes the air by circulation wind path 17 turn back and lead to the wind path 40 on top from the bottom.
And, in the dehumidifier 39 of such formation, (flow losses of air that enter wind path 40 from the origination side that turns back are few in the outside of the opposition side of the origination side that turns back of wind path 40, therefore be easy to the force and velocity of a current flow, wind speed is high and also large part of air quantity) be provided with jut 42, in these jut 42 parts water is flowed down from water filling section 45, by this water that flows down the air by wind path 40 is cooled off and condense.
This water filling section 45, from wind path 40 stretch out and below open, by shielding portion 47, kept out the wind with respect to wind path 40.Therefore, the wind by wind path 40 can not arrive water filling section 45, so, can make existing such rolling of the injected water that produces because of the above-mentioned like that air by dehumidifier 39 be difficult to occur.
Therefore, the situation that rolled-up water enters pressure fan 25 and/or further enters heater 28 can also be reduced, the possibility of the reduction of the reduction of performance, the reduction in life-span and the reliability that cause these pressure fans 25 and heater 28 can be eliminated.
Therefore, in dehumidifier 39, can increase air to the contact of water, can improve wet-out property, therefore can access the drying property of expection.
And, in the above-described configuration, complete cycle in the wind path 40 in dehumidifier 39 is provided with jut 42, therefore, even the whirling vibration of the cylinder 12 that occurs in the biasing of the washings of the inside of cylinder 12 in reason and/or the reasons such as being obliquely installed of rinsing maching that the inclination of face causes are set by rinsing maching, cause in the situation of dehumidifier 39 run-off the straights, water is flowed at the face of this incline direction, make aqueous dispersion by the jut 42 that is present in this face.
Therefore, even dehumidifier 39 run-off the straights also can access good wet-out property.
And, the wall of water filling section 45 belows of dehumidifier 39 is formed inclined plane 49, thus, the water that injects from water filling section 45 can not be splash but flow swimmingly, so can make rolling of injected water more be difficult to occur.
In addition, dehumidifier 39 be made as have in inside that the air that makes by circulation wind path 17 turns back and one of the reason of structure of leading to the wind path 40 on top from the bottom is, for example for can be in circulation wind path 17 can from above insert and place lint filter unit 21 with pulling out and be provided with on the top of water jacket 8 and have the top wind path 18 that filter places section 19.In addition, be for so that have the dehumidifier 39 that makes the wind path 40 that water flows down to the bottom from top, be connected in top wind path 18.
Fig. 8 to Figure 11 represents the second embodiment of the present invention and the 3rd embodiment (the second and the 3rd embodiment), and also description thereof is omitted to the identical Reference numeral of the part mark identical with the first embodiment respectively, only different parts described.
(the second embodiment)
In Fig. 8 and the second embodiment shown in Figure 9, at dehumidifier 39, the jut 42 that replaces the projection by small circular among the first embodiment to consist of, and be provided with multistagely with the jut 61 of the long rib shape that extends of direction of the flow direction quadrature of air by wind path 40.
In addition, the one side of wind path 40 (be the face 40d of pipeline cover 37 inboards this moment), by so that the each other mutual different mode setting of staggering in the transverse direction position of jut at different levels 61, thereby make water can run down into the in turn jut 61 of subordinate.
By such setting, the water that injected wind path 40 is flowed along jut 61, can make it become more with contacting of air by wind path 40, so can access more good wet-out property.
(the 3rd embodiment)
In Figure 10 and the 3rd embodiment shown in Figure 11, at dehumidifier 39, replace above-mentioned jut 61, and jut 71 is set, be set to extend more longways also the gradually helical form of reduction in the direction that the flow direction with air by wind path 40 intersects.
By such setting, the water that injected wind path 40 is flowed along jut 71, also can make this moment it become more with contacting of air by wind path 40, so can access more good wet-out property.
And at this moment, water flows along jut 71 until run into air by wind path 40, so guaranteed the air-supply path of air and reduced fan resistance, can improve air-supply efficient, and can seek the raising of drying property.
(the 4th embodiment)
To the 4th embodiment shown in Figure 15, be provided with the jut 42 of a plurality of rib shapes at Figure 12 at the inner surface of wind path 40, this jut 42 is mutually different and tilt to the longitudinally (above-below direction) of rising portions 34, is arranged to so-called labyrinth-like.
And in this water filling section 45, as shown in figure 15, the both sides of shielding portion 47 link to each other with two medial surface 46b, the 46c one of bellying 46, thus, surround water filling section 45 with bellying 46 and shielding portion 47, so that water filling section 45 becomes the water filling chamber.In addition, shielding portion 47 as shown in figure 12, makes the bottom from the inner surface separation of rising portions 34, makes thus water filling section 45 open downwards, and covers air to the inflow of water filling section 45 by shielding portion 47.
In addition, with respect to the gas outlet 51 of the suction inlet of the described pressure fan 25 that is connected in the topmost that is formed on rising portions 34, the suction inlet of pressure fan 25 is represented by 25a in Figure 13, departs from configuration from the straight line extended line of the wind path 40 of dehumidifier 39.
In the above-described configuration, injected the water of wind path 40, the inner peripheral surface at wind path 40 from inclined plane 49 moves, and then falls, moves at jut 42 from a plurality of juts 42, and flows down downwards.With respect to this water that flows down, in the wind path 40 of dehumidifier 39 from below the air that flows upward, this water splash and contact with this water, thereby make its cooling and the dehumidifying of condensing.
And, the wall of water filling section 45 belows of dehumidifier 39 is formed inclined plane 49, thus, the water that injects from water filling section 45 can not splash but flow swimmingly, therefore can make rolling of injected water more be difficult to occur, therefore can also more reduce rolled-up water enter pressure fan 25 and/or and then enter heater 28, can further eliminate the possibility that performance reduces and/or the life-span reduces and reliability reduces that causes these pressure fans 25 and heater 28.
In addition, form the turn back dehumidifier 39 of the formation that flows into wind path 40 of air by circulation wind path 17, the flow losses of the air of the opposition side of origination side so this turns back (A by the right side of Figure 12 represents) little and mobile easily, so wind speed is high, on the contrary, large and the flow difficulties of the flow losses of air (the left side A by Figure 12 represents) of origination side of turning back, cause wind speed low, with respect to this, the wind path area of section enlarged of wind path 40, the direction in the outside of the opposition side of the origination side that turns back enlarges wind path 40.Thus, can reduce in high-speed side the wind speed of the air that passes through wind path 40, can more effectively make rolling of injected water be difficult to occur.
In addition, as shown in figure 13, the suction inlet 25a of pressure fan 25 configures from the straight line extended line of the wind path 40 of dehumidifier 39 with departing from, also can make thus rolled-up water can enter pressure fan 25 not at all.
In addition, the wall of the below of the water filling section 45 of dehumidifier 39 can not be inclined plane 49, but is curved surface 490 as shown in figure 16.
In addition, the shielding portion 47 of water filling section 45, as shown in figure 17, also can make both sides not link to each other and it is separated slightly from this two medial surface 46b, 46c with two medial surface 46b, the 46c one of bellying 46, by such formation, utilize bellying 46 and shielding portion 47 to surround water filling section 45, make water filling section 45 become the water filling chamber.
(the 5th embodiment)
In the 5th embodiment shown in Figure 180, water filling section with dehumidifier 39, by water filling section 45 with water filling section 76 so that the mode of height and position different (comparing water filling section 45 makes water filling section 76 be in lower position) is provided with a plurality of (they are two this moment), set the water injection rate of the water filling section 45 of this upside to such an extent that lack than the water injection rate of the water filling section 76 of downside.
Above-mentioned water filling section 76, except directly (not via the part that has enlarged the wind path area of section) arranges from wind path 40, consist of identical with water filling section 45, have the bellying 72 identical with bellying 46, with shielding portion 47 identical shielding portion 73 and with water filling port 48 identical water filling port 74, water filling port 74 is connected in the bifurcations of feed water valve 16 by the water filling flexible pipe identical with water filling flexible pipe 50 (not having diagram).In addition, the wall of water filling section 76 belows is inclined plane 75.
In the situation that this formation, at first, dehumidifier 39 has a plurality of water filling section by making water filling section 45 and water filling section 76 be in the differing heights position, thereby the water filling scope with respect to wind path 40 is increased, so can improve wet-out property.And, by the water injection rate of the water filling section 45 of upside being set less than the water injection rate of the water filling section 76 of downside, thereby reduce the water injection rate near pressure fan 25 1 sides, can make injected water more be difficult to occur with respect to rolling of pressure fan 25.
In addition, to lack the in shortage of the integrated injection water yield that causes because the water injection rate of the water filling section 45 of upside is compared with the water injection rate of the water filling section 76 of downside, can be replenished fully by the water injection rate of the water filling section 76 of downside.
(the 6th embodiment)
In the 6th embodiment shown in Figure 19, the wind path area of section from the part of jut 42 with a plurality of rib shapes in the wind path 40 of dehumidifier 39 enlarges gradually towards the top shown in long inclined plane 81.
At this moment, if for example the wind path area of section with jut 42 parts is made as A, wind speed is made as a, to be made as B apart from the wind path area of section in the downstream of jut 42 part 5cm, wind speed is made as b, to be made as C apart from the wind path area of section in the downstream of jut 42 part 10cm in addition, wind speed is made as c, the wind path area of section of the forefield of pressure fan 25 is made as D, wind speed is made as d, then A<B<C<D, thus, a>b>c>d can make wind speed be accompanied by that the wind direction downstream is moved and reduces gradually, near the part of pressure fan 25 reducing wind speed at utmost.
By such setting, in the part near pressure fan 25, injected water just can not rolled because of wind speed, therefore can make this moment injected water more be difficult to occur with respect to rolling of pressure fan 25 yet.
(reference example)
In reference example shown in Figure 20, only be provided with jut 42 in the bottom of the wind path 40 of dehumidifier 39, the part of (upstream side) is provided with wind path area of section enlarged 91,92 by multistage (being two-stage this moment) above it, and, the wind path area of section enlarged 91 of upstream side therein similarly is provided with water filling section 93 with described water filling section 45,76.
Therefore, water filling section 93 also has the bellying 94 identical with bellying 46, with shielding portion 47 identical shielding portion 95 and with water filling port 48 identical water filling port 96, water filling port 96 is connected in the bifurcations of feed water valve 16 by the water filling flexible pipe (not have to illustrate) identical with water filling flexible pipe 50.In addition, the wall with water filling section 93 belows forms inclined plane 97.
So also can make the wind speed gradually reduction along with downstream movement by the air of wind path 40, can make injected water be difficult to occur with respect to rolling of pressure fan 25, especially, the water that splashes at the jut 42 of the wind path area of section enlarged 91 of subordinate, utilize the deceleration effect of the wind that the wind path area of section enlarged 92 by the higher level produces in its downstream, can prevent that this water from arriving the heater 28 in pressure fan 25 and its downstream.
In addition, the present invention not merely is defined in above-mentioned and illustrated embodiment, for example the jut shown in the 3rd embodiment 71 can not be helical form but zigzag that incline direction replaces, in addition, whole as clothes dryer, can only have functions/drying, perhaps also can take functions/drying as main etc., in the scope that does not break away from main idea of the present invention, can suitably change and implement.
