In the above conventional device, the dehumidifier is water-cooled. Specifically, the dehumidifier has an air passage for passing air from the lower part to the upper part, and injects water from the upper part. The air passing through the air path is dehumidified by cooling and condensing.
In this case, the water that is injected and falls is rolled up into the air passing from the lower part to the upper part of the air passage. The rolled up water may be sucked into the blower on the downstream side of the circulation air path from the dehumidifier and enter the blower, and further sent out to the blower and enter the heater on the downstream side. As a result, there is a possibility that the performance of the blower and the heater, the lifespan, and the reliability are lowered.

  The present invention has been made in view of the above circumstances, and therefore, the object thereof is to provide a water-cooled dehumidifier in the circulation air passage, and to prevent the injection water from being rolled up by the air passing through the dehumidifier. To provide a dryer.

  In order to achieve the above object, in the clothes dryer of the present invention, an outer box, an outer tub disposed inside the outer box, and an inner tub disposed in the outer tub for water flow and ventilation. A drum having a possible hole, a driving device for rotating the drum, a circulation air passage disposed around the outer periphery of the outer tub, and a circulation air passage provided in the circulation air passage for circulating the air inside the outer tub A blower that circulates through the circulation air passage and returns to the inside of the outer tub through the circulation air passage, a dehumidifier that is provided in the circulation air passage and dehumidifies air passing through the circulation air passage, and the circulation air passage And a heater for heating the dehumidified air, and the dehumidifier has an air passage through which air passes from the lower part to the upper part, and the upper part extends from the air path. It has a water injection part that is opened downward and shielded from the air passage, and is injected from this water injection part The is characterized in that shall dehumidification by cooling condensing air passing through the air passage (invention of claim 1).

  According to the above means, the water injection part exists in the upper part of the dehumidifier having an air passage for passing air from the lower part to the upper part, but projects from the air passage and opens downward to be shielded from the air passage. Therefore, the wind passing through the air passage does not reach the water injection section, and thus it is possible to make it difficult for the injected water to be rolled up by the air passing through the dehumidifier.

The heater 28 is provided with an electric heater (not shown) as heating means inside a case 29, and a flexible duct 30 having a bellows-like flexible portion 30 a at the outlet of the case 29. Are connected at one end. The flexible duct 30 is generally L-shaped with the other end facing downward, and the other end of the flexible duct 30 is connected to the upper left portion of the back portion 8b of the outer tub 8 (outer tub). 8 is connected to the upper part of the rear air passage 31 provided in the upper right part in FIG.

  As shown in detail in FIG. 1, the dehumidifying duct 24 has a cylindrical falling portion 32 that is long in the vertical direction, a hollow folded portion 33 formed in an arc shape, and a long length in the vertical direction. And a cylindrical rising portion 34. Among them, the falling part 32 has an inlet 35 connected to the connection port 23 of the upper air passage 18 at the upper end, and is formed so as to extend vertically downward from the inlet 35 part. ing. The folded portion 33 is formed so as to be folded upward at the lower end portion of the falling portion 32, and the rising portion 34 is formed so as to extend vertically upward from the folded portion 33.

  FIG. 6 shows a duct main body 36 and a duct cover 37 constituting the dehumidifying duct 24 described above. Among these, the duct main body 36 constitutes the entire falling portion 32 and constitutes most of the folded portion 33 and most of the rising portion 34. On the other hand, the duct cover 37 constitutes a part of the folded part 33 and a part of the rising part 34, and the duct cover 37 is put on the duct main body 36 and joined by a plurality of screws (not shown). A folded portion 33 and a rising portion 34 are formed.

  As shown in FIG. 1, a drain port 38 that protrudes downward is provided at a slightly higher portion on the rising portion 34 side than the lowermost portion of the folded portion 33. Although not shown, the drain port 38 is connected to one end of a drain tube, and the other end of the drain tube is connected to the downstream side (outside of the machine) from the drain valve.

  The rising portion 34 constitutes a dehumidifier 39, and the configuration thereof will be described in detail below. In other words, an air passage 40 extending in the vertical direction and a bypass passage 41 extending in the vertical direction are provided inside the rising portion 34. Among them, a plurality of ribs 42 are provided on the inner surface of the air passage 40, and these ribs 42 are staggered in the longitudinal direction (vertical direction) of the rising portion 34 in a so-called labyrinth shape. Provided.

  On the other hand, the bypass passage 41 is formed with a rib 43 that is separated from the air passage 40 and a rib 44 that is parallel to the upper portion 43a of the rib 43, and is formed in a narrower passage shape than the air passage 40. The thing corresponding to the rib 42 is not formed. Further, the upper end portion 41a of the bypass passage 41 is provided so as to be inclined toward the air passage 40, and accordingly, the upper portion 43a and the rib 44 of the rib 43 are inclined toward the air passage 40.

  The air passage 40 expands the upper air passage cross-sectional area by extending the upper portion 40a to the side opposite to the bypass passage 41 side (falling portion 34 side). A water injection portion 45 is formed on the outer side of the portion where the cross-sectional area of the air passage is enlarged, that is, the upper portion 40a protruding from the air passage 40. The water injection portion 45 includes a hollow bulging portion 46 that bulges from the upper portion 40a of the air passage 40 and bulges to the side, and a shielding portion 47 that shields the air passage 40 side of the bulging portion 46. The water inlet 48 is formed on the upper surface 46 a of the bulging portion 46.

  In the water injection part 45, as shown in FIG. 7, the shielding part 47 has both side parts integrally connected to both inner side surfaces 46b, 46c of the bulging part 46, thereby bulging the water injection part 45. The portion 46 and the shielding portion 47 are enclosed so that the water injection portion 45 becomes a water injection chamber. Further, as shown in FIG. 1, the shielding portion 47 has a lower portion separated from the inner surface of the rising portion 34, whereby the water injection portion 45 is opened downward and is shielded from the air passage 40 by the shielding portion 47. I try to do it.

Further, the rising portion 34 has a wall surface below the water injection portion 45 as an inclined surface 49.
As shown in FIG. 5, one end of a water injection hose 50 is connected to the water injection port 48 outside the rising portion 34, and the other end of the water injection hose 50 is a branch port (not shown in detail) of the water supply valve 16. The tap water is supplied through the water injection hose 50 from the branch port that is open during drying.

In addition, an air outlet 51 (see FIG. 1) connected to the suction port of the blower 25 is formed at the uppermost portion of the rising portion 34, and the suction port of the blower 25 is connected to the air outlet 51. As shown by 25a in FIG. 2, the arrangement is shifted from the linear extension of the air passage 40 of the dehumidifier 39.
Further, FIG. 6 shows ribs 52, 53, and 54 formed on the inner surface of the duct cover 37 together with the ribs 42, and these include the majority of the folded portion 33 and the most peripheral portion of the rising portion 34. , And the ribs 43 and 44, respectively.

Next, the operation of the above configuration will be described.
In the above configuration, when drying the laundry (not shown) accommodated in the drum 12, the fan 15 is driven and heated while the drum 12 is rotated in the forward and reverse directions at a low speed by the motor 15. The electric heater of the vessel 28 is heated, and the branch port of the water supply valve 16 is opened, and water is supplied from the branch port to the water injection part 45 (water injection port 48) of the dehumidifier 39 through the water injection hose 50.

  Among these, the air in the circulation air passage 17 is blown into the inside of the outer tub 8 and thus the inside of the drum 12 from the blowing port 11 by the air blowing action of the blower 25, and the air inside the drum 12 and thus the air inside the outer tub 8. Is repeatedly blown out from the outlet 10 of the outer tub 8 to the circulation air passage 17, whereby the air inside the outer tub 8 (inside the drum 12) is circulated through the circulation air passage 17 (arrow in FIG. 4). reference).

  The flow of the wind at this time will be described in a little more detail. The air in the circulation air passage 17 is heated by the electric heater of the heater 28, and the heated air (warm air) passes through the flexible duct 30 and the rear air passage 31, and passes through the blowing port 11 to the outer tub 8. The inside of the drum 12 is supplied. The warm air supplied to the inside of the drum 12 heats the laundry inside the drum 12 and removes moisture from the laundry. The warm air deprived of moisture from the laundry flows out from the outlet 10 to the circulation air passage 17, passes through the flexible duct 20, and flows backward through the upper air passage 18. If the air flowing through the upper air passage 18 contains lint, most of the lint is captured by the lint filter unit 21, and the lint that has passed through the lint is also captured by the fixed lint filter.

  The warm air that has flowed through the upper air passage 18 flows downward from the upper portion 32 in the dehumidifying duct 24 and then turns upward at the turn-up portion 33, and the air passage 40 and the bypass passage of the dehumidifier 39. 41 (inside the rising portion 34) flows upward from below (see arrows in FIGS. 1 and 2).

  At this time, since the water from the branch port of the water supply valve 16 is supplied to the water injection unit 45, water is injected from the water injection unit 45 into the dehumidifier 39 (the air passage 40). The water injected into the air passage 40 travels from the inclined surface 49 to the inner peripheral surface of the air passage 40, and further falls down from the plurality of ribs 42 or along the ribs 42. With respect to the water flowing down, the air flowing from the lower side to the upper side of the air passage 40 of the dehumidifier 39 is cooled, condensed and dehumidified in contact with the water while splashing the water.

  The water generated by dehumidifying the air passing through the air passage 40 is stored in the inner bottom portion of the dehumidifying duct 24 together with the water flowing down the dehumidifier 39, and the water level increases the height of the drain outlet 38. After exceeding, it is discharged from the drainage port 38 to the drainage channel through the drainage tube connected thereto.

  The air flowing through the air passage 40 of the dehumidifier 39 is sucked into the blower 25 and then sent to the heater 28 where it is heated again by the electric heater of the heater 28. The heated air flows through the flexible duct 30 and the rear air passage 31 as described above, and is returned from the blowing port 11 to the inside of the outer tub 8 and then to the inside of the drum 12. As the air is circulated in this manner, the laundry inside the rotary drum 12 is dried.

  As described above, in the above configuration, the dehumidifier 39 provided in the circulation air passage 17 for circulating the air inside the outer tub 8 (inside the drum 12) has the air passage 40 through which the air passes from the lower portion to the upper portion. The air passing through the air passage 40 is cooled and condensed by the water injected from the water injection part 45 provided on the upper part of the dehumidifier 39 (on the downstream side of the air passage 40). The water injection portion 45 projects from the air passage 40 and opens downward, and is shielded from the air passage 40 by the shielding portion 47. Therefore, the wind passing through the air passage 40 does not reach the water injection section 45, and thus it is possible to make it difficult for the conventional water to be raised by the air passing through the dehumidifier 39 as described above. Therefore, it is possible to reduce the intrusion of the rolled-up water into the blower 25 and further to the heater 28, and there is a possibility that the performance of the blower 25 and the heater 28 are reduced, the life is shortened, and the reliability is lowered. Can be eliminated.

  In addition, in the above-described configuration, the wall surface below the water injection part 45 of the dehumidifier 39 is the inclined surface 49, whereby the water injected from the water injection part 45 flows smoothly without splashing, so Therefore, the intrusion of the rolled-up water into the blower 25 and further the heater 28 can be further reduced, and the performance and life of the blower 25 and the heater 28 are reduced. In addition, the possibility of causing a decrease in reliability can be further eliminated.

  Furthermore, in the thing of the said structure, the wind speed of the air which passes the air path 40 is blower 25 by enlarging the air path cross-sectional area of the upper part 40a downstream from the rib 42 part of the air path 40 of the dehumidifier 39. It is possible to reduce the injection water at the portion close to the blower 25 and to prevent the injection water from winding up at the wind speed at the portion close to the blower 25, and to further prevent the injection water from being wound up on the blower 25. In addition, in this case, the cross-sectional area enlarged portion of the air passage 40 is a part of the air passage 40, and the occupied space by it can be kept small.

Further, in the dehumidifier 39 configured to flow into the air passage 40 by wrapping the air passing through the air circulation duct 17, the side opposite to its folded source side flow loss of the air (shown by W ₁ in FIG. 1) less high wind speed because the easy flow is in the folded root side as opposed to the air (shown by W ₂ in FIG. 1) is low hardly wind flow flow loss is large circumstances, contrast, the wind wind path 40 The road cross-sectional area enlarged portion expands the air path 40 in the direction of the outer side opposite to the folded back side. Thereby, the wind speed of the air which passes the wind path 40 can be reduced on the high speed side, and it can make it difficult to produce the injection water more effectively.

Further, the upper portion 43a of the rib 43 that forms the bypass passage 41 in the dehumidifier 39 is inclined toward the air passage 40, thereby changing the flow of air through the air passage 40, and the air enters the blower 25 straight. I'm trying to keep things from happening. As a result, even a slight amount of water that has been rolled up can be prevented from entering the blower 25 easily.
Further, as shown in FIG. 2, the suction port 25 a of the blower 25 is arranged so as to be shifted from the linear extension of the air passage 40 of the dehumidifier 39, so that even slightly swollen water enters the blower 25. It can be made easier.

In addition, the wall surface below the water injection part 45 of the dehumidifier 39 may be a curved surface 61 as shown in FIG.
Further, as shown in FIG. 9, the shielding portion 47 of the water injection portion 45 is not separated from both inner side surfaces 46 b and 46 c of the bulging portion 46, but is slightly separated from both inner side surfaces 46 b and 46 c. In such a configuration, the water injection part 45 may be surrounded by the bulging part 46 and the shielding part 47 so that the water injection part 45 becomes a water injection chamber.

  10 to 12 show the second and third examples (second and third embodiments) of the present invention and a reference example, respectively, in the same parts as the first example. Are denoted by the same reference numerals, description thereof is omitted, and only different portions are described.

[Second Embodiment]
In the second embodiment shown in FIG. 10, a plurality of water injection sections of the dehumidifier 39 are provided with different height positions between the water injection section 45 and the water injection section 71 (with the water injection section 71 positioned lower than the water injection section 45). (In this case, two) are provided, and the water injection amount of the upper water injection unit 45 is set smaller than the water injection amount of the lower water injection unit 71.

  The water injection part 71 has the same configuration as the water injection part 45 except that the water injection part 71 is provided directly from the air path 40 (without passing through the part where the air path cross-sectional area is enlarged). , A shielding portion 73 similar to the shielding portion 47, and a water injection port 74 similar to the water injection port 48, and the water injection port 74 is connected to a water supply valve via a water injection hose (not shown) similar to the water injection hose 50. It is connected to 16 branch ports. The wall surface below the water injection section 71 is an inclined surface 75.

In this case, first, the dehumidifier 39 has a plurality of water injection portions with different height positions in the water injection portion 45 and the water injection portion 71, thereby increasing the water injection range with respect to the air passage 40, thus increasing the dehumidification performance. be able to. And by setting the water injection quantity of the upper water injection part 45 smaller than the water injection quantity of the lower water injection part 71, the water injection quantity near the blower 25 is reduced, and the injection water is wound up to the blower 25. It can be made more difficult to occur.
In addition, the shortage of the total water injection amount due to the water injection amount of the upper water injection unit 45 being smaller than the water injection amount of the lower water injection unit 71 can be sufficiently compensated by the water injection amount of the lower water injection unit 71.

[Third embodiment]
In the third embodiment shown in FIG. 11, the air passage cross-sectional area from the portion having the rib 42 in the air passage 40 of the dehumidifier 39 is gradually enlarged upward as indicated by the long inclined surface 81.

  In this case, for example, the airway cross-sectional area of the rib 42 part is A, the wind speed is a, the airway cross-sectional area 5 [cm] downstream from the rib 42 part is B, the wind speed is b, and 10 [cm] from the rib 42 part. If the downstream air passage cross-sectional area is C, the wind speed is c, the air passage cross-sectional area of the blower 25 nearest part is D, and the wind speed is d, then A <B <C <D, whereby a> b > C> d, so that the wind speed can be gradually reduced as it goes downstream, and the wind speed can be reduced most in the portion close to the blower 25.

  By doing in this way, injected water does not wind up by the wind speed in the part close | similar to the air blower 25, Therefore It can make it difficult to produce the hoisting with respect to the air blower 25 also in this case.

[Reference example]
In the reference example shown in FIG. 12, the rib 42 is provided only in the lower part of the air passage 40 of the dehumidifier 39, and the air passage cross-sectional area is divided into a plurality of stages (in this case, two stages) above (upstream). Enlarged portions 91 and 92 are provided, and a water injection portion 93 is provided in the upstream air passage cross-sectional area enlarged portion 91 in the same manner as the water injection portions 45 and 71.

  Accordingly, the water injection part 93 also has a bulging part 94 similar to the bulging part 46, a shielding part 95 similar to the shielding part 47, and a water inlet 96 similar to the water inlet 48. The water supply hose 50 is connected to the branch port of the water supply valve 16 through a water injection hose (not shown). The wall surface below the water injection section 93 is an inclined surface 97.

  Even in this case, the wind speed of the air passing through the air passage 40 can be reduced in order as it goes downstream, and it is possible to make it difficult for the injected water to wind up to the blower 25, and in particular, the lower air passage breaks. The water splashed by the rib 42 of the area expanding portion 91 reaches the blower 25 and the heater 28 further downstream from the downstream side due to the wind reduction effect by the air passage cross-sectional area expanding portion 92 on the upper stage. Can be prevented.

  In addition, the present invention is not limited to the embodiments described above and shown in the drawings. In particular, the embodiments may be implemented in combination as appropriate, and the entire machine has only a drying function. It can be implemented with appropriate modifications within a range not departing from the gist, such as having a drying function or having mainly a drying function.
