Abstract

(57) [Abstract] [Purpose] To provide a heating device for preventing cooling of the lower limbs of an employee in cold weather (such as in winter or undercooling) when sitting on a chair and performing sitting. [Structure] An electric heater consisting of a sheet-shaped ceramic or carbon black heating element, a heat insulating material, and a reflector is sequentially installed in an internal space along the lower surface of the top plate of a desk, work table, etc. used for sitting Therefore, the upper surface of the large part of the sedentary worker can be heated and radiated.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heating device for preventing cooling of the lower limbs of a sitting worker who sits on a chair and performs office work, study, or handwork.

[0002]

[Prior art]

 Since sedentary workers sit and sit on chairs and work for a long time, if the temperature in the room falls below 25 ° C, the feet and large parts may become cold, which can lead to poor physical condition especially for girls. Often sue. To this end, unless the floor space is heated even if the entire working room is heated, the temperature in the room is higher in the upper part than in the lower part, and if the feet are kept at an appropriate temperature, the temperature in the head is too high and the head is kept in an appropriate temperature. Then, it is general that the feet are not at the proper temperature.

Since it is technically difficult and costly to heat the entire room to an appropriate temperature, in practice, a portable heating device is placed on a proper place on the floor, or an employee puts his / her own lower body in each one. Ad hoc methods such as wrapping blankets with blankets are used. However, such a heating or heat retaining means often restrains the worker's standing for a while and is not preferable in terms of appearance.

[0004]

[Problems to be solved by the device]

 From the above, efficient heating for sedentary workers does not cover the entire lower limbs and is performed with a small amount of electric power, and this heating device is installed in advance on a desk, workbench, etc. It is desirable that the structure is such that when the worker is seated, heating at an appropriate temperature is started on the spot. Furthermore, when engaging in reception office work, it is necessary for this heating device to be structured so that it cannot be seen by an outpatient while leaving the desk.

[0005]

[Means for Solving the Problems]

 When you are sitting on a chair, the lower body is warmed even if you do not wrap the entire lower body, but if you warm or heat the area from the upper surface of the large part to the knee joints evenly, you will feel warm. This is clear from the fact that, for example, when riding on a rickshaw, when the lap is draped over the upper surface of the large part, the entire lower half of the body suddenly becomes warm.

The present invention applies this point to limit the range of heating to the upper surface of a large part, and to improve efficiency by using an electric heater having a ceramic or carbon black heating element body as a heating device, Furthermore, this electric heater is a device installed downwards at a position along the lower surface of the top plate of the desk so that the worker's standing is not restricted and the purpose is achieved.

【Example】

 The drawing shows an example of an electric heater according to the present invention, in which a planar ceramic or carbon black heating element body 3 and a heat insulating material 2 are fitted to a hollow rectangular frame body 1, and a reflector plate 4 is attached. It is formed on the mounted face piece. In FIG. 3, 5 is a power cord and 6 is a switch.

As is apparent from FIG. 2, this electric heater is attached to a space along a top plate such as a desk or a work table, for example, a drawer provided on the bottom face of the top plate or a bottom face of a shelf plate a. It is used to turn on the switch 6 to heat the ceramic or carbon black heating element body 3 (2 is a heat insulating material) to generate far infrared rays. Then, this heating is amplified downward through the reflection plate 4 so that the irradiation is efficiently performed. The reflection plate 4 may have a flat shape or a concave shape to enhance the reflectance.

The attachment of this electric heater to a desk, workbench, etc. is performed by using an adsorbing tool 7 made of a ferrite magnet piece provided in advance on the upper surface of the electric heater in a steel desk or the like. In such cases, an adhesive tape or the like is used.

[0010]

[Effects of the Invention] As described above, according to the present invention, a worker is provided through a drawer provided along a top plate such as a desk or a workbench, and an electric heater provided on a lower surface of a shelf plate or the like. The lower limbs are always warmed without being restricted in standing, and the heating is performed by the ceramic or carbon black heating element that operates with a small amount of electric power and generates heat, which is far infrared radiation. From the results of actual use, it was found that heating by electric power of 70 W per electric heater was performed by radiation of 80 ° C., and the heating was necessary and sufficient. Since conventional electric heaters, etc. also require 700 W of electricity per person, it was necessary to add additional power receiving equipment, which was not possible due to increased costs.
