SUMMARY OF THE INVENTION The above prior art is disclosed in
In JP-A-8-196797, the main purpose is to reduce noise, and a cushioning material is attached to the inner surface of the wall of the rotating drum. With this configuration, heat radiation from the warm air inside the drum to the surrounding air of the drum is suppressed, As a result, it leads to energy saving. However,
Since the prior art does not mainly aim at energy saving by heat insulation of the drum and the box-shaped casing, even though a slight heat-insulating effect of the drum can be expected, heat insulation of the outer frame casing cannot be expected. There is a problem that heat radiation from the surface of the frame housing cannot be prevented or suppressed.

In order to achieve the above object, according to the present invention, a drying chamber for holding clothes, heating means for supplying warm air to the drying chamber, and blowing means are provided inside a box-shaped housing. In the clothes dryer stored in the above, the box-shaped casing had a double structure including an outer member and an inner member, and a heat insulating member was inserted into a gap between the outer member and the inner member. Here, one is that the heat insulating member is an air layer, the thickness of the air layer is suppressed to a gap size that does not cause convection in the air, and the air in the air layer communicates with the surrounding air. It is kept in a substantially sealed state without performing.

Here, the principle of drying the clothes in the rotary drum type clothes dryer is already known, so the description is omitted. However, during the drying operation, the hot air 4 circulating in the rotary drum 3, which is the drying chamber 2, becomes high temperature and the surrounding air becomes high. The temperature level is much higher for air 11. For this reason, in the conventional clothes dryer, the heat of the high-temperature hot air 4 in the rotary drum 3 is reduced by the combination of heat radiation (heat radiation), heat convection, and heat conduction. In many cases, the air escapes to the surrounding air 11 outside the housing 1 through the housing 1, and the heat loss due to the extra heat radiation lengthens the drying time of the clothes, and the drying efficiency of the clothes dryer often deteriorates.

Next, an embodiment of the present invention will be described with reference to FIG. In the present invention, the box-shaped casing 1 has a double structure including an outer member 20 and an inner member 21.
A thin air layer 22 is formed in the gap between the inner member 21. Here, the air layer 22 serves as a heat insulating member, and a gap in a thickness direction thereof will be described later. However, the air in the air layer 22 is suppressed to such a size that heat convection does not occur in the air, and the air layer 22 The inside air is in a substantially sealed state without communicating with the housing surrounding air 11 and the drum surrounding air 12.

Here, the substantially closed state does not mean that the air in the air layer 22 does not communicate with the surrounding airs 11 and 12 at all, but means that a slight gap that is unavoidable due to its structure is allowed. That is, no opening is provided. If the thermal expansion of the air in the air layer 22 is expected to be large due to the temperature change, only one small opening may be provided in either the outer member 20 or the inner member 21. In this case, since there is only one opening that can communicate with the surrounding air 11 and 12, air enters and exits slightly due to expansion and contraction of air in the air layer 22 due to temperature change.
It does not reach convection. Of course, if a completely sealed state can be achieved, it is better to ensure completeness.

If the outer member 20 and the inner member 21 can form a completely closed double structure, the fluid forming the air layer 22 is not air at atmospheric pressure (normal pressure), but low-pressure air, and further, a vacuum layer. It may be. In addition, depending on the situation, a gas with very poor heat conductivity may be filled, or a heat insulating material with poor heat conductivity such as urethane or glass wool may be inserted,
Further, the heat insulating material may be composed of hollow fine particles or the like.

c and the bottom surface 1d of the housing, and further, the front surface 1e of the housing having the door 10 is desirably provided. When installation on all surfaces is difficult, installation is preferentially performed on the housing upper surface 1a and the left and right side surfaces 1b and 1c of the housing. This is because the three surfaces have a large amount of heat radiation.

Next, the details of the heat insulating air layer 22 will be described with reference to an enlarged view of a portion A in FIG. FIG. 3 is an enlarged view of FIG. 3, in which the thickness S23 of the air layer 22 in the double structure constituted by the outer member 20 and the inner member 21 is suppressed to a gap size where convection does not occur in the internal air.

Here, the reason why the thickness of the air layer 22 is suppressed to a gap size where convection does not occur in the air inside the air layer 22 is as follows. One of the two opposing surfaces, for example, the inner member 2
Radiation from one to the other, for example, to the outer member 20 via the air layer 22 is performed by a combination of three forms of radiation (radiation), conduction, and convection. Here, the radiation is in two planes 2
Almost independent of the thickness of the air layer 22 between 0 and 21, conduction and convection depend on the thickness of the air layer 22. In other words, when the layer thickness is small, convection hardly occurs in the air, and heat is transmitted by conduction and radiation. However, when the layer thickness is large, the amount of heat radiation rapidly increases due to the convection of the air that has begun to occur in addition to the radiation and conduction. . For this reason, it is necessary to suppress the amount of heat radiation in order to improve the heat insulation performance for energy saving, and for that purpose, convection is not generated in the air in the air layer 22.

Optimum layer thickness S23 that does not cause convection
Is determined by the installation direction (horizontal direction, vertical direction) of the two surfaces 20, 21 and the temperature level. This is because the convection is generated when the internal air is heated by the high-temperature surface (the inner member 21) and rises, and is cooled by the low-temperature surface (the outer member 20) and descends. Here, the optimum layer thickness S23 does not have to be as thin as possible. If the structure permits, it is desirable that the thickness be as thick as possible within a range where convection does not occur. This is because when the layer thickness is reduced, the distance over which heat is transmitted is shortened, and there is a concern that the amount of heat released by conduction is increased.

When the optimum air layer thickness S23 which does not cause convection in the rotary drum type clothes dryer is obtained, it is as large as about 10 to 20 mm from the temperature level and the like. However, due to the structure, if the clothes dryer attempts to secure the air layer thickness S23 of about 10 to 20 mm, the size of the housing 1 increases,
Is reduced in diameter. From this result, the optimum air layer thickness S23 for preventing the casing 1 from becoming larger and the drum 3 from becoming smaller in diameter is:
It is necessary to suppress the thickness to less than that, and about 1 to 5 mm is considered appropriate. In addition, more desirably, S = 2 to 3 mm
It is about.

One method is to use the outer member 20 and the inner member 2.
1 is to apply a heat insulating paint or a heat reflective paint to each surface. The heat-insulating paint or heat-reflective paint having a low emissivity and increasing the heat reflection efficiency may be applied to both surfaces of the outer member 20 and the inner member 21, or may be specified only on one of the surfaces in some cases. It may just be applied. It is most desirable to apply the coating to the opposing surfaces of the outer member 20 and the inner member 21. The paint is preferably a material that is thin, has low emissivity, and has a high heat reflection effect and a high heat insulation effect. One of the paints having such characteristics can be obtained by making semiconductor oxides or the like into fine particles and dispersing them in a paint binder.

Further, as another method, a low emissivity material having a high heat reflection effect and having an adhesive instead of the heat insulation paint and the heat reflection paint is attached to the surfaces of the outer member 20 and the inner member 21. Is also good. For example, an aluminum foil tape having a low emissivity and having an adhesive may be attached to one side. In this case, since the emissivity is small, the reflection effect can be expected more than the heat insulation effect. Of course, the low-emissivity material does not need to include an adhesive, and may be the adhesive itself. Furthermore, the low-emissivity material is
0 and the surface of the inner member 21 may be coated directly by plating or the like.
