Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry washing machine having an air passage provided with a plurality of holes provided in an inner bottom portion of an inner tub.

[0002]

2. Description of the Related Art A conventional drying and washing machine is constructed as shown in FIG. The configuration will be described below.

As shown in FIG. 9, a casing 51 is provided with an outer tub 53 which is elastically suspended by a plurality of suspensions 52, and the suspension 52 absorbs vibration during dehydration. Inside the outer tub 53, an inner tub 54 containing a laundry and an object to be dried (hereinafter referred to as clothes) is rotatably arranged around a washing / dehydrating shaft 55 having a hollow double structure. Rotor blades 56 for stirring clothes are rotatably arranged on the inner bottom of the tank 54. Further, a large number of small holes (not shown) are provided on the inner peripheral wall of the inner tank 54, and a fluid balancer 57 is provided above.

A motor (driving means) 58 is attached to the bottom of the outer tub 53, and a clutch 59 for switching the transmission of rotational force to the washing / dehydrating shaft 55 at the time of washing or dewatering and a washing / dewatering shaft 55 through the inner tub 54. Alternatively, it is connected to the rotor 56. The rotary blade 56 has a substantially pot-like shape having an inclined surface that increases in the outer peripheral direction on the outer peripheral portion, and forms a protruding rib for stirring,
In the drying process, the clothes are easily lifted up along the inclined surface by the centrifugal force generated by the rotation of the rotor blades 56.

The drying blower 60 blows hot air heated by the heater 61 through the expandable bellows-shaped hose 62 into the inner tub 54 from the hot air outlet 63, and is located substantially above the housing 51. The drying air blower 60 and the heater 61 constitute a hot air blower. Circuit 64
Is for dehumidifying moist warm air, one end of which is connected to the lower bellows-shaped hose 66 connected to the drainage path port 65 of the outer tub 2 and the other end of which is connected to the drying blower 60.

The drain valve 67 is fixed to the bottom of the outer tank 52,
The drainage from the lower bellows-shaped hose 66 and the circulation path 64 is guided to the drainage valve 67 through the drainage path 68, and drained out of the machine from the drainage hose 69. The outer tank cover 70 airtightly covers the upper surface of the outer tank 52.
An inner lid 71 is provided at 0 so as to be openable and closable so that clothes can be taken in and out.

The operation of the above configuration will be described. In the washing process, the inner lid 71 is opened, clothes and water or hot water and detergent are put into the inner tub 54, and when the operation is started, a water supply valve (not shown) is opened to supply water to a predetermined water level, and then the motor. 5
Drive eight. At this time, the clutch 59 of the transmission mechanism is set to the washing side, the power of the motor 58 is transmitted to the rotating blade 56 via the washing shaft, and the rotating blade 56 rotates, so that the clothes are stirred by the rotating blade 6. It is caught by the projecting rib 61 and drawn into the center. The clothes in the lower center part of the inner tub 54 are pushed up to the upper part of the inner tub 54 by the drawn clothes. In this way, the clothes in the inner tub 54 are stirred and washed by rubbing due to contact between the clothes or the inner tub 54 and the rotating blades 56.

In the dehydration process, after the washing is completed, the drain valve 69 is opened to drain the water in the inner tub 54, and then the clutch 59 of the transmission mechanism is switched to the dehydration side so that the power of the motor 58 is passed through the dehydration shaft. The water is separated from the clothes by transmitting it to the inner tub 54 and rotating it to give a centrifugal force to the clothes.

In the drying process, the drain valve 67 is opened and
The motor 58 is driven to rotate the rotary blades 56, and centrifugal force is applied to the clothes so that the clothes are splashed to the outside. Then, the inclined surface of the rotary blades 56 exerts a force for splashing the clothes upward (component of centrifugal force), and the clothes are agitated. While repeating this stirring, hot air is blown into the inner tank 54 through the upper bellows-shaped hose 62 by the air blow by the drying blower 60 and the heat generation by the heater 61. The hot air removes water from the clothes, then flows from the inner tub 54 to the inside of the outer tub 53, and then passes through the lower bellows-shaped hose 66 to reach the circulation path 64.

Warm air that removes moisture from clothes and contains moisture
When passing through the inner wall of the outer tub 53 and the inside of the circulation path 64, dew condensation of moisture occurs inside, and the moist warm air is dehumidified and returns to the drying blower 60. By circulating warm air in the circulation path 64, the clothes in the inner tub 54 can be dried.

[0011]

In such a conventional structure, when the clothes are dried in the outer tub, the warm air heated by the heater hits the upper clothes in the inner tub but lower clothes. It was hard to hit and the drying efficiency was poor. In order to dry the lower clothes, the rotor blades were stirred to replace the upper and lower clothes, but at this time the clothes are entangled with each other and wrinkles occur on the clothes after drying, which tends to deteriorate the finished state. there were.

The present invention solves the above-mentioned problems by increasing the drying efficiency by uniformly applying warm air to the clothes in the inner tank, and preventing the clothes from wrinkling by preventing the clothes from being entangled. It is intended to improve the finish of clothes after drying.

[0013]

In order to achieve the above object, the present invention is constructed by providing an air passage having a plurality of holes in an inner bottom portion of an inner tank and rotatably connecting an upper end of the air passage. There is. Then, the warm air blown by the warm air blowing means is blown out from a plurality of holes in the air passage in the inner tank so as to hit the clothes in the inner tank evenly, and by the air passage in the inner tank, The clothes are separated.

As a result, the clothes in the inner tub can be evenly hit, so that the clothes can be dried efficiently, and by separating the clothes in the inner tub by the air passage, the clothes can be separated from each other. It is possible to prevent the entanglement of the clothes, suppress the occurrence of wrinkles in the clothes, and improve the finish of the clothes after the drying.
