Abstract

PURPOSE:To obtain a warming apparatus excellent in usability, by providing the main body of the apparatus with a heat generating body and magnets. CONSTITUTION:A warming apparatus main body 4 has on its undersurface a heat generating body 5 and permanent magnets 6. The magnetic force of these magnets 6 is in such a range that the warming apparatus can be secured in position but can be readily removed by one's hands. If required, electromagnets 7 may be added to increase the reliability of the mounting. In this arrangement, the apparatus can be secured to a magnetizable surface such as the undersurface of a desk. Even when the undersurface of the desk is not a magnetizable surface, the magnets may be attached to suitable positions thereof so that the present apparatus may be mounted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heating device used for heating by attaching the main body of the heating device to the underside of a desk or the like.

Structure of conventional example and its problems Conventionally, this type of heating appliance has a heating element 2 such as an electric heater installed in the heating appliance main body 1, as shown in FIG. It was designed to be attached to the bottom surface, etc. Therefore, mounting 9 requires metal fittings, and holes must be drilled in the surface for installation, which not only causes scratches on the desk, but also requires installation and removal work. However, there is a problem in that it cannot be easily and freely installed in various locations.

Purpose of the Invention The present invention solves these conventional problems, and is extremely user-friendly in that it is not a bulky package that can be easily attached to the underside of a desk, etc., and can be removed with a single touch. This provides an excellent heating device.

Structure of the Invention In order to achieve the above object, the present invention has a structure in which a heating element and at least one magnet are provided in the main body of the heating device.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 2 and 3. FIG. 2(a) shows a bottom view, and FIG. 2(b) shows a top view. 4
1 is the main body of the heating device, to which a heating element 5 is attached and permanent magnets 6 are provided at the four corners of the back side. The magnetic force of these permanent magnets 6 is set within a range that securely fixes the heating device and allows it to be easily removed by hand.

Further, as a magnet, an electromagnet 7 may be added to the awn in order to improve reliability during attachment, and in this embodiment, two electromagnets are added. This electromagnet 7 has sufficient magnetic force to provide sufficient strength of the device to prevent dangers such as dropping when energized. In the case of removal, the electricity is turned off and the magnetic force is only from the permanent magnet 6, so it is unlikely that it will fall, but it can be easily removed.

With the above configuration, this type of heating device, which conventionally required troublesome work such as attaching metal fittings and screwing, can be easily fixed to a magnetic surface such as the underside of a desk. Furthermore, even if the underside of the desk is not made of magnetic material, it may be possible to attach it in the same way by applying magnetic material to various places.

In addition to steel, materials such as wood and plastic can be used for the underside of the desk, but materials other than these magnetic materials can also be fixed in the same way by attaching a magnetic material such as a thin metal plate 8 as shown in Figure 3. I can do it.

In addition, when a PTC heating element is used as the heating element 5, the temperature of the body of the heating device is self-controlled to a certain constant temperature due to the PTC characteristics, and when used on the underside of a desk, etc., burns due to contact with the device, etc. Even if the heat generating element 5'f is improperly set and dropped, it is very safe as there will be no burns or ignition.Furthermore, by making the heating element 5'f flat, inconveniences such as knees hitting each other are eliminated.

Originally, this type of heating device was intended for all purposes, not only for raising the room temperature, but also for local heating, and for that reason, the ease of attaching and detaching using magnets is very good in the sense that it increases the versatility of the mounting position. It has certain characteristics.

Effects of the invention (1) Easy to attach to the underside of a desk, etc., and has excellent usability.

(2) A single heating device can be easily moved and used anywhere you like.
