Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage case containing a desiccant and the like.

A number of methods have been invented to preserve dried materials at low humidity, including the use of desiccant agents such as quicklime and silica gel.

However, in drying equipment that regenerates desiccant by heating and uses it repeatedly, the storage case is made of a perforated thin plate made of aluminum alloy in order to increase the efficiency of suction and discharge of the desiccant and the thermal conductivity during regeneration. was. As a heating means for regeneration, an electric ε-heater is often provided in close contact with the storage case.

When installing the electric heater outside the storage case - and - Aside from that.

1. Because the electric heater protrudes into the storage case, it is difficult to fix the storage case.

2. Thermal efficiency is poor because the heat heated by the electric heater radiates not only from the side of the storage case that is in close contact with the desiccant, but also from the opposite side.

3. If the mounting surface and heat transfer surface of the electric heater are not connected to a wall, the area of this wall reduces the moisture absorption area and impedes the uniformity of moisture absorption.

In addition, in cases where the electric heater is built into the storage case, 1. The storage capacity of the desiccant is reduced by the volume of the electric heater, so the entire storage case must be made larger to ensure moisture absorption capacity. There must be.

2. Insulation measures and lead wire extraction structure become complicated.

3. Repairing or replacing the electric heater is troublesome.

There were other drawbacks.

The present invention solves the drawbacks of the conventional storage case described above, and includes a flexible planar heating element constructed by embedding heating wires in an insulator, with numerous small holes bored in the insulating part of the heating wire. To provide a noise storage case which can generate heat uniformly over the entire surface of the box, is small in size, and can be easily installed in a drying device, instead of configuring the box with a planar heating element.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In FIG. 1, reference numeral 1 denotes a planar heating element, and this planar heating element 1 is composed of a flexible resin thin plate.

A heating wire or a printed electric heater 2 is embedded as a heat source in the thin plate. Numeral small holes 3 are provided between the electric heaters 2, which are insulating parts of the planar heating element 1, and are smaller than the particles of desiccant or the like.

The planar heating element 1 is formed into a substantially U-shape. 6 is a notch provided on the outer periphery of the planar heating element 1.

In Fig. 3, 7 is a metal mounting frame formed in a substantially U-shape, and has numerous small holes 3 and mounting holes 8 at both upper and lower ends. This projection is provided at a position facing the notch 6 provided on the outer periphery of the planar heating element 1 shown in FIGS. 1 and 2.

In such a configuration, the planar heating element 1 in which the electric heater 2 is embedded is bent from the folded portion 6 to form a substantially U-shape, and the planar heating element 1 configured in the U-shape is Protrusion 9
configuring the box body with a substantially U-shaped mounting frame 7 having
Alternatively, a storage case as shown in FIG. 4 can be constructed.

FIG. 5 shows another embodiment of the present invention, in which a protrusion 1o is provided on the planar heating element 1 instead of the mounting frame 7, and this protrusion 1
A storage case is constructed by providing six folded portions on the o.

When a granular desiccant is stored in a storage coos constructed in this manner and used in a drying device, the following effects can be obtained.

1 Since the storage case is composed of sheet heating element 1,
Uniform heat generation is achieved over the entire surface of the storage case, further improving desiccant regeneration efficiency.

2. Since the electric heater 2 is embedded in the planar heating element 1, there are no unnecessary protrusions, and the storage case can be made smaller, so it can be easily installed even in a narrow space.

3. Since countless small holes 3 are provided on the entire surface of the planar heating element 1, when a desiccant is contained, the moisture absorption performance of the desiccant can be uniformly exhibited.

4. Since the electric heater 2 is embedded in the sheet heating element 1 made of resin, there is no need for insulation measures, and the connection terminals 4 can be easily drawn out, and many other advantages can be obtained.

As is clear from the above description, the storage case of the present invention is
A sheet heating element is constructed by embedding a heating wire in a flexible insulator, and numerous small holes are provided in the insulator located between the heating wire and the sheet heating element is used to form a box. Due to the structure of the box, when a desiccant is stored in the box and used in a drying device, the entire surface of the box generates heat uniformly, thereby further improving the regeneration efficiency of the desiccant.

Furthermore, since the heating wire is embedded within the planar heating element, there are no unnecessary protrusions, and the box can be made compact, which is also advantageous for mounting on the surface.

Furthermore, since countless small holes are provided on the entire surface of the planar heating element O, when a desiccant is stored, effects such as uniform moisture absorption performance can be obtained.
