Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage heater that obtains warm air by a heat storage method that uses late-night power with a low power consumption unit price.

[0002]

2. Description of the Related Art As a conventional heat storage heater, for example,
There is one disclosed in JP-A-7-294017 by the applicant. Such a heat storage heater stores heat in the heat storage block at midnight and radiates the heat stored in the daytime to heat it.
The heat storage block must be large and heavy depending on the heating capacity. Usually, the lighter one weighs 100 kg and the heavier one 200 kg.

As a lower support structure for supporting the conventional heat storage heater, as shown in FIGS. 10 and 11, a block base 90 on which a heat storage block 99 is mounted is fixed on a rectangular frame 91. The four corners of the frame 91 are supported by the pillar members 92, the lower ends 93 of the pillar members 92 are placed on the pillar support members 94, and the four corners of the thin plate are attached inside the undercover 95 that is shallowly bent. As a result, the weight of the heat storage block 99 is supported on the floor surface from the frame 91 via the pillar member 92, the pillar support member 94, and the under cover 95.

The undercover 95 is for protecting the pillar support member 94 and the lower surface of the entire heat storage heater. Since it is made of a very thin steel plate, it does not serve as a strength member, and also the four corners. The reason for shallowly bending is to improve the installability of the pillar support member 94 and to attach the front, rear, left and right housings.

A thin damper case 96 is mounted below the block base 90, and a damper (not shown) is mounted in a space formed by the block base 90 and the damper case 96 to enable temperature control.

[0006]

The conventional heat storage heater described above has a sufficient heating performance for a room and is fixed to the floor. Therefore, there is a problem that it cannot be used for warming by moving a heater relatively close to a person like a so-called oil stove that burns oil and an electric stove that heats a heating wire with electricity.

[0007] The reason for not moving or not moving is
Since it is not a weight that can be lifted, it is necessary to have casters or the like in order to make it movable. But,
Even if the caster is attached, the support structure of the lower part of the conventional heat storage heater cannot support the heat storage heater due to insufficient strength of the under cover 95 and the like. Further, if the thickness of the plate material of the under cover 95 is increased with the structure as it is, the supporting structure itself becomes heavy, and the durability of the caster is lost. In other words, the conventional design is a design concept in which the weight of the block, housing, etc. is supported on the floor through the undercover, and since it suffices to support the vertical weight, it is a design that considers it to be movable. Didn't. As a result, it has not been possible to meet the demand for making the heat storage heater movable.

The present invention has been made in view of the above problems, and provides a heat storage heater having a lower support structure capable of supporting the weight of the heat storage heater and freely moving the floor surface. Is the main issue.

Since it has 2, it is significantly strengthened against deformation forces such as bending, twisting, and shearing, compared with a simple flat plate.

The pillar member 71 is a wall-shaped member which is continuous in the front-rear direction of the housing, unlike the pillars provided at the four corners as in the prior art. Therefore, a large load such as the heat storage body 3 can be dispersed and received, and the load bearing performance is improved. Since the base member 72 receives the distributed load over the entire width of the base member bottom surface 723 in the front-rear direction, not the concentrated load on a part of the base member bottom surface 723, the load on the base member 72 is reduced. ing.

No burden on 3.

Since the block support member 10 has a box structure in which the block base 11 and the damper case 12 are combined, a large load such as the heat storage body 3 is applied to the wall surface of the box structure (the front and rear walls 124 of the damper case 12). By receiving it, it has the necessary load resistance. Further, by bridging the left and right pillar members 71, the strength of the box structure formed by the base member 72 and the pillar members 71 is further increased. As a result, a simple and lightweight structure in which the frame in the left-right direction in the conventional frame structure is omitted is obtained.

Therefore, by attaching the casters 73 to the lower supporting structure 7 which has the required strength and is light in weight, the heavy heat storage heater 100 can be made movable. There is.

The caster 73 has a lock lever 73.
Since 1 is provided, it is possible to secure safety by moving to a necessary place and locking it.

In the conventional fixed type, the wall is often carved and installed, and it is necessary to open the front cover for maintenance, whereas the heat storage heater 1
In No. 00, since it is movable, maintenance can be performed in a wide area, and the housing 2 can be formed by the front cover 21 that integrally covers the front surface and both side surfaces, and the number of parts can be reduced.

According to this embodiment, the pair of left and right pillar members 71 continuous in the front-rear direction of the housing 2 support the weight of the heat storage block 31, and the casters 73 serve as the pillar members 7.
Since it can be attached to the lower surface of the base member 72 below 1, the large load of the heat storage body 3 and the like can be dispersed and received, the load bearing performance is enhanced, and the casters 73 are attached to the floor surface freely. It is a heat storage heater with a lower support structure that can be moved to.

Further, the pillar member 71 is fixed inside the front and rear walls 721 of the base member 72 with the flange 711 facing toward the center side, and the base member 72 and the pillar member 71 form a box structure, which is lightweight and high. Load-bearing performance is obtained.

The block support member 10 forms a box structure with the block base 11 and the damper case 12, and the damper case 12 has left and right pillar members 71.
Thus, the strength of the box structure formed by the base member 72 and the pillar member 71 can be further increased.

FIG. 9 shows an embodiment (2) of the heat storage heater according to the present invention.

In this embodiment, the pillar member of the lower support structure 7 is changed.

As shown in the sectional view of FIG. 9 (b), the pillar member 74 is a box having front, rear, left and right walls.

According to this embodiment, in addition to the same operation and effect as those of the above-mentioned embodiment (1),
Furthermore, one surface, a wall 747, is added to strengthen the pillar member and enhance the load bearing performance.

The pillar member 71 of the embodiment (1) is used.
As described above, if the notch 716 is formed, the pillar member 74 can be easily formed by bending.
