Abstract

<P>PROBLEM TO BE SOLVED: To shorten the drying period of time by reducing heat transfer from the air duct, through which hot air of a high temperature flows, to the outside. <P>SOLUTION: A surface member 15 is installed by placing an interval at least to the outer peripheral wall section 14 of a housing case 13, or a heating duct 11, or a rotary drum 3. Then, a heat-insulating material 16 is provided at a space between the part of at least the outer peripheral wall section 14 of the housing case 13, or the heating duct 11, or the rotary drum 3 and the surface member 15. Thus, a specification is provided by which the heat transfer from the inside of the air duct through which the hot air of the high temperature flows to the outside can be reduced to increase the heat-insulating effect. Since the hot air of the high temperature enters the inside of the rotary drum at the time of drying, the drying of laundry is accelerated. Thus, the drying period of time for the laundry in the rotary drum can be shortened at the time of washing-drying, and the amount of the consumption power can be reduced. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an oblique drum type washing and drying machine.

  FIG. 11 shows a configuration of a drum-type washing machine according to the prior art. A rotating drum 61 is arranged in a water tub 63 in a washing machine casing 67 so that the rotation axis direction thereof is horizontal. .

  The door 64 provided on the front side of the washing machine housing 67 is opened, and the laundry is put into the rotary drum 61 from the laundry entrance 68 formed in the water tub 63 so as to face the door 64, and the drum is driven. By rotating the rotating drum 61 by the motor 65, the laundry accommodated in the rotating drum 61 is hooked and lifted by the stirring protrusion 66 provided on the inner peripheral wall of the rotating drum 61, and the lifted laundry is appropriate. The laundry is beaten and washed by dropping from a height (see, for example, Patent Document 1).

  By providing the drum-type washing machine having the above-described configuration with a drying function, a drum-type dryer having a function of drying laundry after being dehydrated, wet clothes, and the like in addition to washing can be configured.

  That is, when the air is exhausted from the water tank 63, the air containing the moisture in the rotating drum 61 is discharged from the through holes 62 formed in the peripheral surface of the rotating drum 61. Therefore, the air containing the moisture is passed through the dehumidifying means to dehumidify. After that, the laundry and the clothes accommodated in the rotating drum 61 can be dried by forming an air circulation path for blowing air in the water tank 63 again by the heating means.

However, the drum-type washing machine or the drum-type washing / drying machine has the rotating drum 61 arranged sideways, so that the laundry is taken in and out from the front side, and the pain associated with bending the waist and the narrowness of Japan The structure has been unsuitable for housing conditions. In order to solve the problem of the drum type washing and drying machine, the rotating shaft core is inclined so that the opening side of the rotating drum 61 faces upward, so that the laundry can be easily taken in and out and placed in a narrow space. The drum type washing and drying machine can be configured.

  However, when the rotary drum 61 is inclined forward from the horizontal direction, the laundry stored in the rotary drum 61 is located at a lower position of the rotary drum 61, that is, on the bottom side of the rotary drum 61 formed in a bottomed cylindrical shape. When the rotating drum 61 is further rotated and the laundry lifted in the circumferential direction by being caught by the stirring protrusion 66 provided on the inner peripheral surface of the rotating drum 61 falls from above, the bottom surface side of the rotating drum 61 Therefore, the rotation of the rotating drum 61 acts to collect the laundry on the bottom side. Therefore, in an oblique drum type washing and drying machine having a structure in which the rotating drum 61 is inclined, it is necessary to apply warm air uniformly to the laundry to promote drying. However, during drying, water in the rotating drum is stored. Since there is no movement of the laundry due to the flow of water and the laundry becomes lighter as drying progresses, it becomes difficult to receive the stirring action by the stirring protrusion 66 provided on the inner peripheral surface of the rotating drum 61. Since the laundry easily collects on the bottom surface of the rotating drum 61 and the drying action does not reach all the laundry uniformly, drying unevenness and wrinkles occur, it is difficult to dehumidify, the drying time is long, and the power consumption is large. Had.

The heat pump unit 10 of the oblique drum type washing and drying machine 2 having a structure composed of the body) can reduce the amount of heat entering from the outside. Therefore, heating is promoted, and heat transfer from the inside of the air passage of the storage case 13 through which high-temperature hot air flows at the time of washing and drying can be reduced and the heat insulation effect is enhanced. Since warm air enters, the drying of the laundry is promoted, and the drying time of the laundry in the rotary drum 17 can be shortened at the time of washing and drying, and the power consumption can be reduced.

  In addition, as the heat insulating material 16, styrene foam, urethane, glass wool, or the like can be used.

  As shown in FIG. 8, four stirring protrusions 25 (two in the figure) are provided in the rotating drum 17 of the water tank 7 of the oblique drum type washing and drying machine 2. The stirring protrusion 25 is mounted in the rotary drum 17 as an asymmetric structure on the left and right and up and down. Accordingly, since the laundry (not shown) in front of the rotary drum 17 rotates evenly before and after the rotary drum 17 during washing and drying, the laundry is rotated in front of and behind the rotary drum 17 during washing and drying. It is easy to move to the surface, and warm air can uniformly hit the laundry and dry it, so it can avoid uneven drying of the laundry, prevent uneven drying and wrinkles, and easily return to the dehumidification duct , Drying time can be shortened and power consumption can be reduced.

  Note that the number of the stirring protrusions 25 may be four or more. In this case as well, the stirring protrusions 25 may be attached to the inside 17 of the rotating drum as an asymmetric structure on the left, right, and top.

(Embodiment 9)
FIG. 9 is a perspective view of the stirring protrusion in the drum of the oblique drum type washing and drying machine in the ninth embodiment of the present invention.

  As shown in FIG. 9, the through-hole 22 of the stirring protrusion 25 has a structure in which the front-side through-hole 23 is made larger than the back-side through-hole 24, and the through-hole 22 is made smaller toward the back surface. Since the through-hole 22 is arranged smaller as it goes to the inner surface, warm air flows through the front surface of the rotating drum 17 (not shown) during washing and drying, and it is easy to circulate back to the dehumidifying duct 12 (not shown). Generation of wrinkles can be prevented, drying time can be shortened, and power consumption can be reduced.

  In the present embodiment, the through holes 22 are gradually made smaller from the front to the back. For example, the two rows on the front are the same size, and the next two rows are the front. The through holes may be smaller than the two rows and have the same size, and may be reduced step by step.
