Description

  The present invention relates to a vertical laundry dryer that supplies warm air in a drying process after washing to dry clothes.

  Drying clothes (removal of water) using a vertical washer / dryer was not possible to remove water only by dehydration in the subsequent drying process. Hot air is created and blown with a heat source such as a heater while circulating air with a blower fan, and the stirring blades located at the bottom of the washing and dewatering tank rotate left and right to move clothes and efficiently evaporate. . At this time, since water vapor evaporated from the clothes is generated by the warm air, it is necessary to remove the water vapor.

  As a method for removing this water vapor, water-cooled dehumidification in which hot water containing water vapor is cooled by allowing tap water to flow inside a water-cooled dehumidifying duct disposed in the outer tank, and moisture in the water vapor is condensed and removed. A method has been proposed (see, for example, Patent Document 1).

  Here, since the agitating blade arranged at the bottom of the washing and dewatering tub rotates to the left and right to perform the drying operation, the lint that peels off from the clothing as the drying progresses, and remains in the washing and dehydration tub after washing. The waste dust flows into the water-cooled dehumidification duct along with the circulating air, and dust containing this yarn waste (hereinafter referred to as dust) comes to adhere to a part of the water-cooled dehumidification duct in the air passage located in the outer tub. . For the purpose of dehumidifying the circulating air and cleaning the dust, the water-cooled dehumidifying duct has a cooling nozzle through which tap water for dehumidification flows, and dust attached to the wall surface of the duct separately from the cooling nozzle. A cleaning nozzle is attached to remove the water. And this cooling nozzle was made into the structure which flows tap water toward the lower direction of a water-cooling dehumidification duct, and the washing nozzle flowed tap water toward the horizontal direction.

  In addition, in a drum type washer / dryer, in order to wash away dust adhering to the wall surface near the bent portion at the top of the air passage, a washing nozzle is arranged in the longitudinal passage of the air passage, and the lateral, downward and upper sides are arranged. The structure which provided the washing | cleaning port which spouts washing water in the direction is disclosed (for example, refer patent document 2).

A front panel box 12, which is a front housing portion formed between the top cover 9 and the front panel 10, includes a power switch 13, an operation panel 14 having an input switch group and a display element group, and a control unit 15. To do. These constitute a control device. And the rear part of the top cover 9 has a washing water supply means.

  In FIG. 2, the washing water supply means is constituted by a main water supply electromagnetic valve 19 having a water inlet side connected to a faucet connection port 17 and a water outlet side connected to a water injection port 18. Further, a detergent dissolution container 20, a sofna water supply electromagnetic valve 21, and a tank cleaning water supply electromagnetic valve 22 are also provided in the washing water supply means, and have a cooling water supply electromagnetic valve 16 separately from the washing water supply means.

  Further, the washing and drying machine of the present embodiment is formed so as to extend upward in the vertical state along the outer wall surface on the rear side of the outer tub 5 from the exhaust port 5a formed in the lower side wall of the outer tub 5. A water-cooled dehumidifying duct 23 is provided for dehumidifying the damp air flowing from the mouth 5a and sending it to the upper blowing means. The blowing means is supported by the outer frame 1 and supplies air from the upper part of the outer tub 5 into the washing and dewatering tub 2. Specifically, the drying filter 25 removes dust in the circulating air during the drying process. A drying filter case 26 for fixing the drying filter 25, a blower fan 27 that is arranged on the upper side of the dry filter case 26, sucks air into the suction port and sends it out as a wind, and comes out of the impeller of the blower fan 27. A fan casing 32 containing a heater (PTC heater) 31 for heating air and a blowout port 30 for blowing the heated hot air toward the washing and dewatering tub 2 are provided. In addition, the drying filter 25, the ventilation fan 27, and the water-cooling dehumidification duct 23 are arrange | positioned so that a part of each vertical projection may overlap.

  Here, the second temperature sensor 200 is installed in the fan casing 32, and the first temperature sensor 100 is installed in the air passage on the downstream side of the heater 31. In order to accurately detect the temperature of the circulating air dehumidified and dehumidified in the water-cooled dehumidifying duct 23, the second temperature sensor 200 is preferably touched after the water-cooled and dehumidified circulating air is well mixed and uniform. . Accordingly, the second temperature sensor 200 is installed on the downstream side of the drying filter 25 away from the water-cooled dehumidifying duct 23 and before the heater 31 in the fan casing 32.

  The outer garment insertion port 9a formed on the top cover 9 is covered with an outer lid 41 attached to the top cover 9 by a hinge so as to be opened in two (mountain). And the inner clothing input port 28a formed in the outer tank upper cover 28 attached to the upper end of the outer tank 5 is covered with an inner lid 42 attached to the outer tank upper cover 28 by a hinge 42a so as to be freely opened and closed.

  A drain port 5 b formed at the bottom of the outer tub 5 is connected to a drain hose 34 via a drain electromagnetic valve 33. A base 36 made of synthetic resin with legs 35 attached to the four corners is attached to the lower edge of the outer frame 1.

  Furthermore, in this embodiment, as shown in FIGS. 1 and 2, a heat exchange plate 38 is attached with screws to a water-cooled dehumidification duct 23 that is a circulating air passage on the back surface of the outer tub 5. The cooling water 39 flows down along. On the surface of the heat exchange plate 38, ribs (not shown) molded of synthetic resin are provided so as to meander alternately toward the lower side. The cooling water 39 flows down along the meandering ribs of the heat exchange plate 38 installed on the wall surface of the water-cooled dehumidifying duct 23 constituting the circulation air passage, and the water vapor evaporated from the clothing by the hot air is condensed in the cooling water 39 to generate moisture. It has been removed.

  Next, the vertical washer / dryer of the present embodiment has a circulation upstream bellows tube 29a and a circulation downstream bellows tube 29b. The circulation upstream bellows pipe 29 a allows the upper part of the water-cooled dehumidification duct 23 to communicate with the air blowing means (drying filter case 26), and the circulation downstream bellows pipe 29 b communicates with the air blowing means (fan casing 32) and the upper outlet of the outer tub 5. 30. The water-cooled dehumidifying duct 23 of this embodiment is formed integrally with the outer tub 5, and the side wall of the outer tub 5 also serves as a part of the water-cooled dehumidifying duct 23. The water-cooled dehumidification duct 23 communicates with each other at a lower portion thereof, and the outer tub 5 communicates with an exhaust port 5a provided at the lower portion thereof.

  As a result, air that has been cooled and deprived of moisture while rising in the water-cooled dehumidifying duct 23 during the drying process is sent from the upper part of the water-cooled dehumidifying duct 23 to the blowing means via the circulation upstream bellows tube 29a. This air is warmed by the heater 31 in the blowing means, and is supplied as warm air from the upper part in the outer tub 5 via the circulation downstream bellows pipe 29b. As described above, the air deprived of the moisture from the laundry 37 in the washing and dewatering tub 2 is deprived of the moisture in the water-cooled dehumidification duct 23 while circulating through the closed circulation air passage, thereby It is dried. And by providing the circulation upstream bellows tube 29a and the circulation downstream bellows tube 29b, even if the outer tank 5 vibrates and relative displacement occurs between the outer frame 1, these bellows tubes follow and deform. Therefore, the airtightness of the circulation air passage can be secured. Further, the washing and dewatering tub 2 can be rotated at a higher speed, and the dewatering performance is improved. As a result, the entire operation time is shortened.

  However, if the water-cooled dehumidification duct 23 and the drying filter case 26 are connected by a rubber circulation upstream bellows tube 29a as in this embodiment, the water-cooling dehumidification duct 23 and the circulation upstream bellows tube 29a are connected during the drying process. Circulating air may collide with a step on the wall surface near this area, and a lot of dust may adhere to this area.

  Furthermore, the circulation upstream bellows tube 29a of the present embodiment has a shape in which the central axis of the central portion is shifted toward the outside away from the washing / dehydrating tub 2 rather than the central axis of the upstream opening. Yes. Further, the central axis of the downstream opening is shifted to the outer side away from the washing / dehydrating tub 2 rather than the central axis of the central part of the circulation upstream bellows tube 29a. This also causes a large amount of dust to adhere to the lower part of the circulation upstream bellows tube 29a.

  Therefore, in this embodiment, the duct nozzle 24 is provided in the water-cooled dehumidifying duct 23 as a cleaning means for blowing water toward the circulation upstream bellows tube 29a. As shown in FIGS. 3 to 5, the cleaning means of the present embodiment includes a cleaning inlet (cleaning nozzle) 24 a for spraying tap water toward the circulating upstream bellows tube 29 a and cooling water into the water-cooled dehumidifying duct 23. 39 is provided with a cooling inlet (cooling nozzle) 24b through which 39 flows and a common tap water supply unit (water supply port 24c) for supplying tap water to both.

  The dust adhering to the vicinity of the lower end of the circulation upstream bellows tube 29a in the drying process is washed away by the following method in the washing process at the next operation. In the washing process, first, water is supplied from the main water supply electromagnetic valve 19 to the detergent dissolution container 20 and branched at the water injection port 18 and the cleaning port 18a. The detergent dissolution container 20 and the outer tank upper cover 28 are connected by a water injection bellows tube 29, and the water discharged from the water injection port 18 flows through the water injection bellows tube 29 into the washing and dehydration tank 2. The water branched at the cleaning port 18a of the detergent dissolution container 20 passes through the blow hose 40 and communicates with the water supply port 24c of the duct nozzle 24, and the cleaning water 41 flowing in from the cleaning nozzle 24a is discharged diagonally upward. FIG. 3 shows the state of the wash water 41 discharged when the tap water pressure is 0.8 Pa.

  Hereinafter, the configuration of the duct nozzle 24 will be described in detail. FIG. 5 is a front view, a side view, and a bottom view of the duct nozzle 24 of the present embodiment. The duct nozzle 24 has a water supply port 24c connected to the blow hose 40, and a cleaning nozzle 24a and a cooling nozzle 24b are integrally formed on the downstream side thereof. Then, when water is supplied in the washing process, a part of the branched water flows from the water supply port 24c and the internal pressure of the duct nozzle 24 is increased, so that the cleaning water 41 is discharged from the cleaning nozzle 24a in an obliquely upward direction. To wash away. At this time, since the cooling nozzle 24b is also communicated with the duct nozzle 24, a part of the tap water flowing in from the water supply port 24c is discharged from the cooling nozzle 24b.

  Here, the size of the total cross-sectional area of each inlet is adjusted so that the amount of water discharged from the cooling nozzle 24b is the same as or less than the amount of water discharged from the cleaning nozzle 24a. As a result, the washing water 41 is expelled from the washing nozzle 24a vigorously, and the washing water 41 reaches the wall surface of the circulating upstream bellows pipe 29a located above the water-cooled dehumidifying duct 23 where the duct nozzle 24 is installed, and is large. Because it collides with speed, it becomes easy for dust to fall. In addition, at the time of a drying process with a small flow rate of tap water flowing in from the water supply port 24c, water flows evenly from the cooling nozzle 24b only to the heat exchange plate 38.

  Next, the place where the cleaning water 41 is sprayed will be described. When the washing water 41 is discharged directly upward, there is a possibility that the drying filter 25 may be wetted and the drying performance is deteriorated. Therefore, in this embodiment, the water flowing from the cleaning nozzle 24a is obliquely upward toward the circulation upstream bellows pipe 29a located above the duct wall surface on the side facing the duct wall surface on the side where the duct nozzle 24 is provided. The angle was given to the discharge port of the washing nozzle 24a.

  Here, the water pressure of household water supply varies depending on the region, etc., and when the water pressure is high, water is sprinkled upward at a steep angle, and when the water pressure is low, water is sprinkled at a gentle angle and the wash water 41 reaches. The height is different. In the present embodiment, when the pressure is 0.8 Pa corresponding to the maximum water pressure, the connection portion between the upper end of the circulation upstream bellows tube 29a, that is, the upper end of the circulation upstream bellows tube 29a and the blowing means (drying filter case 26). Since the washing water 41 is sprayed in the region from the first to the half of the height of the circulation upstream bellows tube 29a, it is possible to prevent the water from being scattered to the drying filter 25.

  Conventionally, the vicinity of the dry filter case 26 has been cleaned using a care tool or the like, but it has been impossible to clean the circulation upstream bellows tube 29a beyond the dry filter case 26. However, in this embodiment, the cleaning up to the vicinity of the drying filter case 26 can be performed using the cleaning nozzle 24a, so that a higher-grade washing / drying machine can be provided.

  In the present embodiment, the cleaning nozzle 24a and the cooling nozzle 24b are formed integrally to facilitate manufacture, but the momentum of the cleaning water 41 from the cleaning nozzle 24a may be increased by separating them.

  As described above, according to this embodiment, it is possible to effectively wash away dust adhering to the connecting portion between the water-cooled dehumidifying duct 23 and the circulating upstream bellows tube 29a, and dust accumulates over time. It is possible to prevent the air path from being blocked and the drying performance from being lowered. Further, since the circulation upstream bellows pipe 29a also plays a role of absorbing vibrations of the outer tub 5 and the like during operation, dust adhering to the inner surface can be dropped by shaking the circulation upstream bellows pipe 29a. The inner cleanliness is further enhanced.
