Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric heating device which is installed on a floor in a room and used for collecting a human body.

[0002]

[Prior art]

 Conventionally, this kind of electric heating device is provided with a radiant type planar heater on the front surface of the main body and a warm air device including a blade, a casing and a heating element, as disclosed in Japanese Utility Model Laid-Open No. 3-87101. There was a radiant heating system with quiet sound, and a rapid heating system at the beginning of energization and a warm air heating system that was effective when the entire room was to be heated.

[0003]

[Problems to be solved by the device]

 However, in the electric heating device configured as described above, in order to obtain heating for both radiant heating and warm air heating, in addition to the planar heater for radiant heating, a heating element for warm air heating is separately provided. It is necessary to provide it, and it is expensive and uneconomical. In the case of radiant heating, the radiation efficiency is poor because the radiation heat to the front of the sheet heater and the rising air as convection heat are radiated.

The present invention has been made paying attention to such a point, and a single heating element can be used as both a radiant heating element and a hot air heating element, and heat loss due to an ascending airflow in radiant heating can be achieved. It is an object of the present invention to provide an electric heating device that can be actively used to obtain efficient warm air heating.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention has a box-shaped main body case with an open front surface, a casing vertically provided on the back side of the main body case, and a casing in front of the casing. Provided between the heat shield plate and the casing, which is a heat shield plate provided vertically with an appropriate interval, a planar radiant heater provided in front of the heat shield plate, and between the heat shield plate and the casing. A warm air passage having a warm air inlet on one end side and a warm air outlet on the other end side, and a fan provided in this warm air passage are provided.

[0006]

[Action]

 In the present invention, the rotation of the fan is stopped during radiant heating, and radiant heat from the radiant heater provides soft heating. In addition to radiant heating by radiant heat from the radiant heater during warm air heating, the fan is rotated to guide the heat from the radiant heater from the warm air intake port into the warm air passage, where it is discharged as warm air from the warm air outlet. Is done.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

Reference numeral 1 denotes a stand, and a vertically long box-shaped main body case 2 having an open front surface is attached to an upper part of the stand 1. A casing 3 is provided on the back side of the inside of the main body case 2 and extends from the upper portion of the front surface of the main body case 2 in the vertical direction to the stand 1. Reference numeral 4 denotes a heat shield plate which is provided in front of the casing 3 in the vertical direction with an appropriate interval. Reference numeral 5 is a planar radiant heater provided in front of the heat shield plate 4, and the radiant heater 5 is formed of a heating element 7 which is arranged in a meandering shape on a heat insulating board 6 and whose heat generation capacity can be appropriately changed. . Reference numeral 8 denotes a warm air passage provided between the heat shield plate 4 and the casing 3. A warm air suction port 9 is provided at an upper portion of one end side of the warm air passage 8 and a warm air is provided at the other end portion of a lower portion. A wind blow outlet 10 is provided. Reference numeral 11 denotes a heat-resistant metal fan that is rotationally driven by a motor (not shown) and is provided inside the hot air passage 8 so as to face the hot air outlet 10. A baffle 12 is provided for the purpose of preventing the temperature rise to the limiter 13 during radiant heating. Reference numeral 14 is a guard that protects the radiation heater 5. Reference numeral 15 is a power switch, and 16 is a changeover switch for changing the speed of the fan 11.

However, when the electric heating device configured as described above is used, when the power switch 15 is operated to turn on the power, the heat generated by the heat generator 7 of the radiant heater 5 is energized. Radiates to the front of the main body case 2 as indicated by the arrow indicated by the alternate long and short dash line, and radiant heating that is soft and quiet is performed. Next, when the changeover switch 16 is operated to energize the motor (not shown), the fan 11 rotates at a desired speed, and the heat generated by the heating element 7 is generated by the suction force and the rising airflow of the heating element 7 caused by the rotation of the fan 11. A large part of the air is sucked into the warm air passage 8 from the warm air suction port 9 provided in the upper part of the heat shield plate 4 as shown by the arrow shown by the solid line, and warm air is discharged from the warm air outlet 10 as warm air. Therefore, in addition to the above-described radiant heating, rapid heating is performed in the initial stage of energization, and is usually used as warm air heating to warm the entire room. Incidentally, at the time of rapid heating, the heating capacity of the heating element 7 is increased and the fan 11 is rotated at high speed. Further, during normal warm air heating, the heat generation capacity of the heat generating element 7 is set to a medium value and the fan 11 is rotated at a low speed.

In the embodiment of the present invention, the warm air suction port 9 is provided at the upper portion of the warm air passage 8 and the warm air outlet 10 is provided at the lower portion. Alternatively, the warm air outlet 10 may be provided at the lower part of the upper part and the warm air outlet 10 may be provided at the upper part.

[0011]

[Effect of device]

 According to the present invention, one heating element can be used as both a radiant heating element and a hot air heating element, which is inexpensive, and at the same time, the heat generated by the rising air flow of the radiant heater is positively used to provide efficient warm air. An electric heating device capable of heating can be provided.
