BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor-standing type heating device and an indoor heat convection device that can be used together with this type of heating device.

[0002]

2. Description of the Related Art This type of heating device is provided with a heat source for burning fuel such as oil or gas, or a heat source for converting electric power into electric heat such as infrared rays or joules, and heat generated by the heat source is radiated or heated. It radiates heat to the surroundings as wind to warm the room.

FIG. 7 shows the basic construction and operation of a conventional floor-standing stove. The stove 100 is installed or placed on the floor 104 at any desired location in the room 102. The main body of the stove 100 includes a combustion type or electric heating type heat source 10.
6 and a heat reflection plate 10 for efficiently radiating the heat generated by the heat source 106 in a predetermined direction, for example, forward.
And 8 are provided. Radiant heat H from stove 100
Warms the nearby air. The warmed air rises and disperses in four directions near the ceiling 102, so that the ceiling 1
After flowing along 02, it cools down gently (air flow A).

FIG. 8 shows the basic structure and operation of a conventional fan heater. A combustion type or electric heating type heat source 114 and a fan 116 are built in the main body of the fan heater 112,
An air intake port 118 is provided on the back surface, and a warm air outlet 120 is provided on the front surface. When the power switch (not shown) is turned on, the heat source 114 and the fan 116 operate respectively. As the fan 116 rotates, the air on the back side of the heater is introduced into the heater through the air suction port 118. The introduced air passes through the fan 116 and the heat source 114.
After being sent there to and heated there, it is blown out forward from the warm air outlet 120 as warm air. The hot air blown out from the hot air outlet 120 goes straight along the floor 104 for a while, then rises, is dispersed in all directions near the ceiling 110, and gently descends while cooling (air flow B).

Further, the fan heater 112 has a temperature sensor 122 for detecting room temperature provided on the back or side of the main body, and has a built-in temperature controller (not shown). The temperature controller controls the heat source 11 so that the room temperature detected by the temperature sensor 122 matches the set temperature.
The heating value of 4 is controlled.

However, in the stove 100 as shown in FIG. 7, the radiant heat H is locally heated within the range (place), but the warmed air rises to the upper part of the room and the ceiling 110 Easy to stay in the vicinity. Therefore, in the room 102, there is a large temperature difference between the location near the front of the stove 100 and the other locations, and the heating efficiency is low.

A fan heater 11 as shown in FIG.
In the case of 2, the warm air blows out forward, that is, in the horizontal direction, so that it can be warmed immediately even in a distant place. It is also excellent. But,
It is difficult to heat the place where the warm air does not hit, for example, the side (left and right) or the back of the fan heater 112, and the heating efficiency for heating the entire room is still insufficient.
Further, the temperature sensor 1 provided near the air intake port 118
22 is exposed to cold intake air, so fan heater 1
A temperature considerably lower than the temperature of the place where the 12 hot air reaches is detected as the room temperature. However, since the temperature controller operates so that the temperature detected by the sensor 122 matches the set temperature, the vicinity of the front of the heater is likely to be overheated.
Regarding this point, it is possible to perform temperature compensation, but optimal control is difficult because the error in measured temperature is too large.

As described above, in the conventional floor-standing type heating device, it is difficult to efficiently heat the entire room, and there is room for improvement in terms of comfort and energy consumption efficiency.
