Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an electric heating device whose main body is in the form of a sheet, such as an electric carpet, and particularly to an electric heating device with improved operability of switches and the like.

[Technical background of the invention] For example, in the case of an electric carpet, a control unit is attached to a corner of the main body of the carpet. The case of this control unit has conventionally been formed into a rectangular shape, with a recess formed on the outer surface along the outer edge of the carpet, and operating knobs such as switches have been arranged in this recess.

[Problems with Background Art] When operating a switch or the like while sitting on a carpet, there is a problem in that it is difficult to operate because the knob is not in front of the user and is located in a position that is difficult for the user to see.

[Object of the invention] A further object of the invention is to provide an electric heating device that can improve the operability of the control section.

[Summary of the invention] The invention has a recessed part oriented in a direction substantially perpendicular to a straight line extending toward the center of the main body in the central part of the main body of the case of the control unit, and a switch etc. is installed in this recess. By providing a configuration with an operating member, the operating member is located closer to the front where it can be easily seen by the user, improving operability and preventing users from accidentally stepping on the control unit with their foot. This also prevents the risk of damage to the operating member.

[Embodiment of the invention] An embodiment in which the invention is applied to an electric carpet will be described below with reference to the drawings. Reference numeral 1 denotes a carpet which is a sheet-like main body, inside which cord heaters 2 and 3 are arranged in a meandering manner divided into left and right sides. Reference numeral 4 denotes a control unit, and a power switch 6, a changeover switch 7 for selecting whether or not to supply electricity to the two cord heaters 2 and 3, and a temperature control volume 8 are provided in the case 5. There is. Note that the power switch 6, changeover switch 7, and volume 8 are all of a sliding type. The case 5 of the control unit 4 has a substantially right-angled isosceles triangle shape, with one side portion 5a corresponding to the hypotenuse facing toward the center of the carpet 1, and the remaining two side portions 5b and 5c corresponding to the two right-angled sides facing the carpet. It is attached to the corner of the carpet 1 along the outer edge of the carpet 1. Reference numeral 9 denotes a power cord, which has a plug (not shown) inserted into a power outlet at one end, and a connector 10 connected to the case 5 at the other end.
have. The connector 10 is configured to be detachable from the case 5 by operating a lock release button 11. Reference numeral 12 denotes a concave portion, which is located in a portion of the case 5 on the central side of the carpet 1, that is, in the vicinity of one side portion 5a facing toward the center of the carpet 1, so as to be oriented in a direction substantially perpendicular to a straight line A extending toward the center of the carpet 1. One side 5a of the case 5
A depression has been formed along the 13 to 15 are power switch 6, changeover switch 7 and volume 8
These knobs are operating members for use in the recess 12 and are provided so as to protrude into the recess 12 from a long hole 16 formed on one inner surface along the longitudinal direction of the inner surface of the recess 12. It is configured to be movable. Reference numerals 17 to 19 indicate display portions provided on the case 5 in correspondence with the respective knobs 13 to 15. Reference numeral 20 denotes a lid for opening and closing the recess 12, which is pivotally attached to the case 5 so as to be pivotable to open and close in the vertical direction.

According to the above configuration, the knobs 13 to 15 are located on one side 5 of the case 5 facing the center side of the carpet 1.
In this type of electric carpet, which is generally operated while sitting on the carpet 1, since the carpets are arranged near point a along a direction substantially perpendicular to the straight line A extending toward the center of the carpet 1, The knobs 13 to 15 are positioned closer to the user on the carpet 1 and in front of the user, making them easier to see and operate. Also, picking 13 to 15
If the knobs 13 to 15 are provided near one side 5a on the center side of the carpet 1 in the case 5, the chances of scratching when stepping on them will increase.
2, there is no risk of failure such as damage or deformation resulting in the sliding operation becoming impossible. Furthermore, in this embodiment, since the lid 20 is provided to open and close the recess 12, the knobs 13 to 15 are more effectively protected, and there is no possibility that water, dust, etc. may enter.

Note that the operating member is not limited to a slide type, but may be a push button type. Furthermore, the present invention is not limited to electric carpets, and can be widely applied to electric heating devices such as electric blankets whose bodies are sheet-shaped.

[Effects of the invention] As explained above, in the present invention, a recessed portion oriented in a direction substantially perpendicular to a straight line extending toward the center of the main body is formed in the center side of the main body of the case of the control section, and Since the configuration is such that an operating member such as a switch is provided in the front panel, the operating member is closer to the user during operation and is located in front of the user where it is easy to see. This provides an excellent effect in that there is no risk of damage to the operating member even if the operating member is accidentally stepped on.
