DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontally long box-shaped heater suitable for partial heating of a specific place in a room such as a work table or an amusement table installed in a room or a wall surface of the room.

[0002]

2. Description of the Related Art Electric carpets, panel heaters, and the like are known as partial heating in a specific place in a room, for example, heating a foot in a kitchen or the like.

[0003]

The above-mentioned electric carpets and panel heaters have a problem that they are expensive and their mounting locations are specified from the beginning, and their use is limited because they cannot be designed and installed freely. .

Therefore, the present invention is widely used for, for example, a lower end of a cooking table or a sink, a play table sitting on a chair, a work table used for assembling work, a lower end of a wall in a room, and the like. It is an object of the present invention to provide a horizontally long box-shaped heater suitable for partial heating.

[0005]

In order to achieve the above object, according to the present invention, a partition wall is provided at an upper portion in a longitudinal direction in a heat-resistant case having a substantially U-shaped vertical section and a horizontally long shape, and an upper portion of the partition wall is wired. The lower part is a heating element installation room, and a heat insulating material made of a foamed synthetic resin is fixed in the heating element installation room, and polyethylene glycol fine particles are baked at a high temperature to be a semiconductor, and conductive plastic fine particles are obtained. A sheet-like heating element having a positive temperature coefficient, which is obtained by printing a kneaded mixture with a printing ink on a synthetic resin film, is attached to the front surface of the heat insulating material, and the opening of the heat-resistant case is covered with a heat-resistant cover case to be horizontally long. This forms a box-shaped heater.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG. 1, a horizontally long heat-resistant case 1 has a substantially U-shaped vertical section, and its size is 1140 mm in length (horizontal), 145 mm in height (vertical),
A partition wall 2 having a width (thickness) of 12 mm is provided at an upper part in a longitudinal direction in the case, and an upper part of the partition wall 2 is connected to a wiring chamber 3.
The lower part of the partition wall 2 was formed in the heating element installation chamber 4. A heat insulating material 5 made of foamed polyethylene is fitted and fixed in the heating element installation chamber 4, a sheet heating element 6 is attached to the front surface of the heat insulating material 5, and a front opening of the heat resistant case 1 is covered with a heat resistant case cover 7. A horizontal, box-shaped heater 8 was formed.

The sheet heating element 6 is obtained by firing polyethylene glycol fine particles at 2,000 ° C. for 48 hours to be transformed into a semiconductor, and adding a printing ink to fine particles of phenol resin, carbon black or the like, and kneading the mixture. This is formed by printing the resulting polyester film on an insulated polyester film, and has a positive temperature coefficient manufactured by Nippon Special Industries Co., Ltd.

FIGS. 3 and 4 show a side view and a front view, respectively, of a state in which the horizontally elongated box-shaped heater 8 according to the present invention is implemented below the pachinko game board, and the lower part of the player's knee is shown. Heating has been implemented.

The size of the horizontally long box-shaped heater 8 of the present invention is not limited to the above-mentioned size, and the size may be freely selected depending on the mounting place.
1000mm ~ 2000mm, height (vertical) 100mm ~
A size of about 160 mm and a width (thickness) of about 10 mm to 20 mm can be said to be preferable in terms of manufacturing and mounting work.

A connector 9 and a power supply cord 10 are arranged in the wiring chamber 3 above the partition wall 2 and electricity is supplied to the sheet heating element 6 by operating a switch (not shown) to provide an attached temperature control device ( Heating temperature standard designation range 4 by not shown)
The heat is controlled to be radiated in the range of 0 ° C to 65 ° C. Note that the heat generation temperature can be specified in the range of 30 ° C to 80 ° C.
Range.

Although FIGS. 3 and 4 show an embodiment in which the present invention is applied to a pachinko game console,
In addition, for example, the heater according to the present invention is attached to the front surface or the lower surface of the tabletop of the work table, and the lower part is warmed from the knee portion of a person who works while sitting on a chair, or, also, a cooking table, a sink, and a wall surface. It is also a preferred embodiment of the present invention to attach it to a lower end or the like and use it to warm the feet of a person standing indoors.

[0012]

The planar heating element 6 according to the present invention is obtained by kneading fine particles of polyethylene glycol and fine particles of conductive plastic and printing it on a synthetic resin film. It has a uniform density, and can be used safely without the risk of current-carrying failure or abnormal heating due to disconnection or short-circuiting like nichrome wire, aluminum foil, or stainless steel foil.

Further, when the temperature reaches the set temperature, the current value is reduced to 25% to 35% as compared with that at the start of energization, and only the power for compensating the heat dissipation is consumed. When the temperature becomes lower than the set temperature, the current increases and the temperature rises. When the temperature becomes higher than the set temperature, the current is reduced and the temperature is lowered to control the balance between heat generation and heat radiation, thereby reducing power consumption.

Further, since the heater of the present invention has a horizontal shape and a box shape, it can be easily mounted on a cooking table, a sink, an amusement table, a wall surface, etc., and can be widely and effectively used as a partial heating of a specific place in a room.
