BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater device for maintaining the temperature of a simple greenhouse.

[0002]

2. Description of the Related Art When cultivating tropical plants or wintering temperate plants in a general household, a simple greenhouse is used.
This simple greenhouse is constructed by assembling a box frame having a plurality of shelves with a plurality of aluminum strips, surrounding the frame with a glass or resin sheet material, and providing a heater device for maintaining a predetermined temperature inside. It was made.

[0003] A heater device used in this kind of simple greenhouse includes:
Conventionally, the cord heater is laid in a zigzag shape over the entire bottom surface of a flat-plate-shaped metal case, and a thin metal plate (aluminum foil or the like) is stuck on top of it.
Usually, it is set under the bottom shelf in a simple greenhouse.

[0004]

In order to increase the amount of heat radiation in the conventional heater device, it was necessary to increase the plane size of the metal case. However, there are cases where such an increase in size (that is, an increase in the amount of heat radiation) is impossible in relation to the bottom area of the simple greenhouse. In addition, such an increase in size tends to cause temperature unevenness in the metal case, so that there is a problem that the metal case is deformed.

As a conventional heater device, Japanese Utility Model Application No.
Panel heater disclosed in JP-A-8-95908,
Japanese Patent Application Laid-Open No. 8-72888 discloses a radiator disclosed in

These are all used to maintain the temperature in a greenhouse.
It is not intended to be used. That is, general
Because the humidity in the greenhouse is high, the heater used in the greenhouse
Equipment must be regularly maintained
However, the above-described conventional technology has poor maintainability.

[0006] The present invention has been made in view of the above circumstances, and it is possible to increase the amount of heat radiation while suppressing the overall size, and furthermore, the maintenance when using in a greenhouse.
It is an object of the present invention to provide a greenhouse heater device which can ensure the heat resistance .

[0007]

In the present invention, the following technical measures have been taken in order to achieve the above object. That is, the present invention includes a metallic main body case having a rectangular shape in a plan view and a cord-shaped heating device built in the main body case, and the main body case is formed by connecting a base body and the base body. a covering portion body to form a housing portion of the heating device between them, this

[0008]

According to the present invention, by connecting the base body and the cover body, the heat-generating device is held in a tied state between the two (in the main body case), and the heat of the heat-generating device is transferred to the base body and the cover. Since the heat is radiated to the outside through the parts (all are made of metal such as aluminum alloy), the entire peripheral surface of the main body case can be efficiently used as the heat radiating surface. Further, the shape of the main body case can be changed in design according to various requests. By providing an intermediate member between the base body and the cover body, the heating device is held immovably.

By projecting the radiation fins on the outer peripheral surface of the base body or the cover, the heat radiation can be further increased. In this case, if the total heat release amount is determined to be a predetermined value according to the volume of the simple greenhouse, the size of the main body case can be reduced as a whole. In the case where the connection between the base body and the cover body is performed by a fitting structure, the structure of both is simplified and the connection work is also facilitated.

The heater device 1 includes a flat and elongated main body case 2 and a built-in U-shaped heating device 6 as a whole.

As shown in FIG. 3, the main body case 2 includes a base body 4, an intermediate member 5, and a cover body 3, and the base body 4 and the cover body 3 are connected to each other along the longitudinal direction. Device storage section 7 is formed. Two parallel hollow ribs 9 protruding along the longitudinal direction are provided on the inner surface of the cover body 3, and the intermediate member 5 forcibly embraces both outer sides of the hollow ribs 9 in a fitted manner. It is attached to the cover body 3 in such a way. The intermediate member 5 is formed with a device holder 8 having a round bottom groove shape at a portion corresponding to each inner side of the hollow ribs 9, and the heating device 6 is covered with the device holder 3 by the device holder 8. It is designed to be pressed against and held on the inner surface of the. The base body 4, the intermediate member 5, and the cover body 3 are all made of metal, and radiate heat from the heat generating device 6 to the outside. It is preferable to perform extrusion or drawing using an aluminum alloy or the like having excellent thermal conductivity.
There is an advantage that it is easy to manufacture various types having different lengths according to the specifications (capacity of the target simple greenhouse, etc.). In addition, the periphery of the device holding portion 8 in the intermediate member 5 and the periphery of the portion of the cover 3 to which the heating device 6 is pressed are:
The wall thickness was made larger than that of the other parts so as to achieve uniform heat distribution of the entire main body case 2. Reference numeral 10 denotes a thermostat screwed to the cover 3 with a tapping screw 11 or the like, and 12 denotes a ground terminal.

In the present embodiment, a cord-shaped sheathed heater having a diameter of 6.5 mm is used as the heat-generating device 6.
(5 ° C.). The base body 4 and the cover body 3 have a fitting structure formed by a hinge engaging portion 15 formed on one side along the longitudinal direction and a hook engaging portion 16 formed on the other side. The connected state is maintained.

The base body 4 and the cover body 3 are formed with a plurality of radiating fins 20 on the outer peripheral surface thereof. Most of the radiating fins 20 have their projecting directions inclined obliquely, and the projecting length of the radiating fins 20, that is, the radiating area can be increased without increasing the thickness dimension b of the main body case 2. It is designed to be large. The distance P between the adjacent heat radiation fins 20 is set to a dimension (3.45 mm) that does not allow a finger of a standard child size to enter.

An end processing cap 17 (see FIG. 4) made of a thermosetting resin is separately attached to both ends in the longitudinal direction of the main body case 2. The end processing cap 17 is fixed by, for example, screwing a tapping screw 21 into the hollow rib 9 of the cover 3. It is preferable to form a drain gap 23 (see FIG. 1) at the joint between the main body case 2 and the end processing cap 17. A hook fitting 22 is rotatably attached to one end of the end processing cap 17.
By making 2 protruded, the suspended use of the heater device 1 is enabled. The end processing cap 17 can be eliminated by integrally providing closing plates (not shown) at both ends of the base body 4 and the cover body 3 in the longitudinal direction.
