Abstract

PROBLEM TO BE SOLVED: To provide a drum-type washing and drying machine showing stable drying performance while preventing warm air from leaking through an air-blow port.SOLUTION: A drum-type washing and drying machine includes an air-blow port member attached to a cover portion and forming an air-blow port through which air is supplied into a rotary drum. The air-blow port member and the cover portion are sealed by a plurality of sealing members and serve to positionally adjust repulsive force in different three directions that is caused by the sealing members. Accordingly, when the air-blow port member is attached to a removed-water receiving cover, it can be attached in the state where backlash is controlled in these three directions, which allows reduction in quantity of warm air for drying clothing that leaks through a gap, thereby preventing a drying operation from being ended while the clothing is still undried and also preventing the drying operation from being performed for an unnecessarily long time, so that a drum-type washing and drying machine showing stable drying performance can be provided.

Description

  The present invention relates to a drum-type washing / drying machine capable of adding a drying function to a drum-type washing machine and performing each process from washing to drying continuously or arbitrarily selecting a drying process.

  Conventionally, this type of drum type washing and drying machine has a circulation fan that generates hot air for drying clothes. The wind generated by the circulation fan passes through the heater and is heated to change into warm air. The hot air blowing path is attached to the casing that covers the rotating drum, the weight attached to balance the dehydration of the clothes in the drum, and the casing that holds the weight and covers the drum. It is comprised from the cover part which is attached, and the ventilation port member attached to the cover part. (For example, refer to Patent Document 1).

  FIG. 5 is a plan view of the conventional drum-type washing / drying machine after the air outlet is attached. FIG. 6 is a cross-sectional view of the conventional drum-type washing / drying machine after the air outlet is attached. The air blowing member 99 attached to the cover portion 98 puts hot air into the rotating drum 91. Warm air hits the wet clothes after washing and takes away moisture from the clothes. The moist and dry air deprived of moisture passes through the heat exchanger from the rear of the rotary drum 91, returns to the circulation fan and the heater, and changes to warm air again. This repetition dries the clothes. Further, the air blowing port is composed of the air blowing member 99 and the cover portion 98, and is composed of separate parts. However, warm air may leak from a slight gap between the air blowing member 99 and the cover portion 98.

  Moreover, it is possible to prevent leakage of hot air by providing a groove in the cover part, fitting a seal packing, and crushing in a direction parallel to the rotation axis of the rotary drum with a rib provided on the air blowing member.

FIG. 1 shows a cross-sectional view of the electrolyzer according to Embodiment 1 of the present invention. The rotating drum 1 formed in a bottomed cylindrical shape has a rotating shaft inclined in a horizontal or downward direction from the horizontal direction toward the back side as a bottom from the opening front side. The rotary drum 1 is rotationally driven by a motor 3. The control means 4 controls the washing process, the rinsing process, the dehydration process, and the drying process by controlling the motor 3 and the like.

  The water tank 2 has the rotating drum 1 rotatably disposed therein, and has a dehydration receiving cover 8 that is a cover portion on the front side that opens. The air blowing member 9 is attached to the dehydration receiving cover 8, and the air blowing member 9 and the dehydration receiving cover 8 form a blowing port. The air blowing member 9 and the dewatering receiving cover 8 are sealed by a plurality of packings 15 (seal members). The dewatering receiving cover 8 is provided with a rib 10 for pushing the packing 15. The repulsive force of the packing 15 due to the pushing of the rib 10 is regulated in three different directions.

  A detailed configuration of the dewatering receiving cover 8 will be described with reference to FIGS. FIG. 2 is a perspective view before attachment of the dewatering receiving cover and the air outlet in the first embodiment of the present invention. FIG. 3 is a perspective view after attachment of the dewatering receiving cover and the air outlet in the first embodiment of the present invention.

Fig. (C) is a partially enlarged view of the front view after the dewatering receiving cover and the air outlet are mounted in Embodiment 1 of the present invention. FIG. 4D is a right side view after the dehydration receiving cover and the air outlet are attached in Embodiment 1 of the present invention. FIG. (E) is a partially enlarged view of the right side view after the dewatering receptacle cover and the air outlet are attached in the first embodiment of the present invention. FIG. (F) is a partially enlarged view of the right side view after the dewatering receiving cover and the air outlet are attached in the first embodiment of the present invention.

  In FIG. 4, the axial direction C is a direction parallel to the rotation axis of the rotary drum 1. The radial direction F is a direction from the axis of the rotating shaft of the rotating drum 1 toward the outer periphery of the dehydration receiving cover 8. The tangential direction G is the same plane as the radial direction, and is the radial direction and the tangential direction.

  As shown in FIGS. 4 (b) and 4 (c), a radial packing 15 f as a seal member is fitted into a radial groove 18 f provided in the blower port member 9. The radial packing 15 f is crushed in the axial direction C by the radial ribs 10 f provided on the dewatering receiving cover 8. The floating in the axial direction C due to the repulsive force of the radial packing 15 f generated at this time is restricted by the air blowing member 9 holding the radial rib 10 f provided on the dewatering receiving cover 8.

  Further, as shown in FIGS. 4D and 4E, a tangential packing 15g, which is a seal member, is fitted into a tangential groove 18g provided in the air blowing member 9. The packing 15 g is crushed in the direction F by the tangential rib 10 g provided on the dewatering receiving cover 8. The deviation in the radial direction F due to the repulsive force of the tangential packing 15g generated at this time is regulated by holding the boss 17 provided on the dewatering receiving cover 8 with the groove rib 11 provided on the blower port member 9.

  Further, the backlash in the tangential direction G is restricted by the groove rib 11 provided in the air outlet member 9 including the boss 17 provided in the dewatering receiving cover 8.

  Due to the positional restriction effect of the radial ribs 10f, the tangential ribs 10g, and the groove ribs 11, the air blowing member 9 is not attached to the dehydration receiving cover 8 in a lifted state or a shifted state.

  Thereby, the amount of warm air passing between the dewatering receiving cover 8 and the air blowing member 9 from the direction A is reduced. The temperature variation caused by the difference in temperature between the hot air temperature sensor 13 and the return temperature sensor 14 due to assembly is reduced, and problems such as undrying of clothes and longer drying time are eliminated, and a stable drying detection system is configured. can do.

  Further, it is possible to prevent the air blowing member 9 and the peripheral parts from interfering with each other due to the floating of the air blowing member 9.

The same effect can be obtained with the configuration. In the first embodiment of the present invention, the boss 17 is installed in the dewatering receiving cover 8 and the groove 18 is installed in the blower port member 9 as the radial position restriction, but this is a hook shape and a hole, a pin and a hole, etc. The same effects can be achieved with other position restriction configurations.

  The operation of the drying process in the drum type washing machine having the above configuration will be described.

  When the drying process is selected by the control means 4, the circulation fan motor 5 is driven to start rotating. Wind is produced by the rotation of the circulation fan motor 5. The produced wind enters the heater 6 and changes to heated warm air. This warm air passes between the dehydration receiving cover 8 and the air blowing member 9 and enters the rotary drum 1 to take away moisture from the wet clothing and dry the clothing. The wind containing moisture passes through the heat exchanger 12 from the rear of the rotating drum 1, returns to the circulation fan motor 5 and the heater 6, and changes to warm air again. While this is repeated, the end of drying is detected based on the difference temperature between the hot air temperature sensor 13 and the return temperature sensor 14.

  Although the present invention is configured in a drum type washing machine, in the case where the air blowing port is composed of two or more components, a vertical washing machine may be used.

  As described above, the drum-type washing machine according to the present invention can prevent the leakage of hot air from the air blowing port including two components with a simple configuration. Therefore, it is useful not only for drum-type washing and drying machines but also for electric appliances including an air discharge device having a blower port composed of a plurality of components, such as a dishwasher and a vacuum cleaner.
