Description

  The present invention relates to a washing and drying machine, and more particularly to a washing and drying machine provided with an air passage that takes in and flows out air discharged from a washing and dewatering tank.

  As a washing and drying machine equipped with washing, rinsing, washing, dehydration and drying processes, a rotating drum having a rotating shaft in a substantially horizontal direction and rotatably disposed in the water tank is driven by a motor to supply water for washing in the water tank It is known that water is supplied by a valve, blown into a water tank by a blower, a heater is connected to the blower, and moisture evaporated from the laundry in the rotating drum is dehumidified by cooling water by a heat exchanger connected to the blower and the water tank. ing. There, it is disclosed that a rib for collecting foreign matter constituted by a slit-like partition plate is provided in the radial direction intermediate portion of the air passage of the heat exchanger (for example, Patent Document 1).

JP 2004-121352 A (Claim 3, FIG. 1 etc.)

  However, when a member such as a partition plate is arranged in the radial intermediate portion of the air passage as in the above document, there is a problem that the space through which the wind can pass is greatly narrowed. Also, if ribs are provided in the radial middle of the air passage, it is necessary to prepare the ribs as separate parts and insert them into the air passage, which increases the number of parts and the manufacturing process of the washing and drying machine. There were also problems such as.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a washing / drying machine having a configuration capable of maintaining a wide air passage space through which wind can pass as much as possible and collecting lint efficiently. Another object of the present invention is to propose a lint collecting structure that can suppress an increase in the number of parts of the washing machine and a burden on the manufacturing process.

The washing / drying machine of the present invention is a washing / drying machine comprising: a water tank equipped with a laundry dewatering tub; and an air passage that communicates with the inside of the water tub and takes in and flows the air discharged from the laundry dewatering tub. At least one protrusion that protrudes inward of the air path is provided on at least one of the air inlet or the inner wall surface of the air path.
In addition, it is preferable that the said protrusion is integrally molded with the said air path on the bent part by the side of the inlet of the said air path, or the inner wall surface of the air path just before or just after this bent part.
Further, the protrusion may be integrally formed with the air passage on an outer diameter side inner wall surface of a bent portion on the air inlet side of the air passage.

  According to the washer / dryer of the present invention having the above-described configuration, lint contained in the wind flowing through the air passage can be efficiently collected by the protrusions while keeping the air passage space through which the air can pass as wide as possible, and dehumidifying. Adhesion of lint to the container and drying filter can be reduced. Moreover, since the air passage is in communication with the water tank, the lint collected by the protrusions is easily discharged out of the apparatus together with the drainage in the next washing, rinsing and dehydration processes. In addition, according to this lint collection structure, it is possible to increase the number of parts of the washing / drying machine and to suppress the burden of the manufacturing process.

Embodiment 1. FIG.
FIG. 1 is a configuration diagram of a washing / drying machine according to Embodiment 1 of the present invention. The washing / drying machine 1 exits from the washing / dehydrating tub 3 in communication with the water tub (outer tub) 2 in which the washing / dehydrating tub 3 is housed inside the housing (outer box) (not shown). An air passage 11 is provided for taking in the wind and returning it to the washing and dewatering tank 3 again. In the washing / drying machine according to the present invention, the air passage 11 does not necessarily have to be a circulation air passage as shown in FIG. 1. For example, the air coming from the washing / dehydrating tub 3 is taken into the washing / drying machine. Alternatively, it may be a mode of flowing outside.

The water tank 2 is supported by a plurality of suspension rods 4 through the suspension rod support portions 2A, and is configured to be tiltable by raising and lowering the suspension rods 4 by the suspension rod movable portions 4A. An anti-vibration member 6 is disposed at the connecting portion between the water tank 2 and the suspension rod 4 to suppress the influence of vibration applied to the water tank 2.
The laundry dewatering tub 3 is provided with a fluid balancer (not shown) around its upper part, and a pulsator 9 that rotates (inverts) right and left during washing and drying is attached to the bottom.
A motor 7 is attached to the lower side of the water tank 2, and the power of the motor 7 is transmitted to the washing / dehydrating tank 3 and the pulsator 9 through the rotating shaft 8 and used for rotation thereof.

The air path 11, together with the drying filter 13, the fan 14, and the heater 15, constitutes a part of a circulation air path that serves as a flow path for air entering and exiting the washing / dehydrating tank 3. In this example, the air passage 11 is a dehumidifying air passage, and a dehumidifying plate 12 that functions as a water-cooled dehumidifying heat exchanger by flowing water from above is disposed inside the air passage 11.
In this example, the air passage 11 is formed by integral molding with the water tank 2, but the air passage 11 may be configured separately from the water tank 2 and communicated with the water tank 2 using piping and bellows. good.

  When the air passage 11 is integrally formed with the water tank 2, the lower portion 11 </ b> B of the air inlet 11 of the air passage 11 can be stacked (stacked) when the water tank 2 is transported or stored. It is formed in the middle. Correspondingly, the dehumidifying plate 12 is arranged so that the lower end thereof is positioned higher than the air inlet 11 </ b> A of the air passage 11. This is to prevent the dehumidifying plate 12 from being shaken by the water flow during washing or the like, thereby preventing damage due to the pressure. As a result of these, the air inlet 11 </ b> A of the air passage 11 is disposed at a position corresponding to the upper side of the lower end of the dewatering tub side plate of the laundry dewatering tub 3.

  Next, the operation of the washing / drying machine 1 will be described. The washing / drying machine 1 can perform washing, rinsing, dehydration and drying, and the water tank 2 can determine the inclination state according to the stroke. For example, in an easy-to-wash process, it is set upright or inclined according to the amount of laundry. In the dehydration process, the water tank 2 is preferably in an upright state due to its nature. On the other hand, in the drying process, it is preferable to incline the water tank 2 in order to promote stirring of the laundry and increase the drying efficiency.

The washing, rinsing, and dehydration processes are conventional processes, and are performed by the same operation as in the past. Therefore, here, the operation of the drying process will be described.
In the drying process, the pulsator 9 is reversely driven, and the laundry in the laundry dewatering tub 3 is stirred. At the same time, in the drying process, the air (air) containing moisture released from the laundry is discharged into the water tank 2 from the bottom of the laundry dewatering tank 3 or the opening of the side plate by the action of the blower fan 14, and the air is discharged from the air inlet 11A. It is taken into the path 11. The wind taken into the air passage 11 is dehumidified there, filtered by the drying filter 13, heated by the heater 15, and then introduced into the washing / dehydrating tub 3 from the air intake 16. By these actions, the laundry is dried over time.

In the above drying process, lint generated when the laundry is dried may adhere to the dehumidifying plate 12 and the drying filter 13 constituting the circulation air path, and the drying performance may be lowered. Therefore, in the present invention, before the lint generated when the laundry is dried adheres to the dehumidifying plate 12 and the drying filter 13 constituting the circulation air path, the protrusion 20 for collecting the lint is provided on the air path 11. At least one, preferably a plurality, are provided so as to protrude inward.
In addition, although the air path of FIG. 1 is a dehumidification air path provided with the dehumidification board 12 inside, it is good also as an air path of the aspect which does not have the dehumidification board 12. FIG.

Thereby, before the lint contained in the wind passing through the air passage 11 reaches the dehumidifying plate 12 and the drying filter 13 and is caught by the protrusions 20, the lint adhering to the dehumidifying plate 12 and the drying filter 13 is removed. Can be reduced. Therefore, it is possible to prevent the drying performance of the washing dryer from being lowered.
Further, since the air passage 11 communicates with the water tank, the lint collected by the protrusions 20 can be removed together with the drainage and discharged outside the machine in the next washing, rinsing and dewatering processes. It has become. Furthermore, the lint collected by the protrusions 20 is easily removed outside the machine by flowing water from the top to the dehumidifying plate 12 inside the air passage 11.
