DETAILED DESCRIPTION OF THE INVENTION

[0001]

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 which can be used together with this type of heating device.

[0002]

2. Description of the Related Art A heating device of this type 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. The heat is radiated to the surroundings as wind to warm the room.

FIG. 7 shows the basic structure and operation of a conventional floor-standing stove. The stove 100 is installed or placed on the floor 104 at a desired location in the room 102. The main body of the stove 100 has a heat source 10 of a combustion type or an electric heat type.
6 and a heat reflecting plate 10 for efficiently radiating the heat generated by the heat source 106 in a predetermined direction, for example, forward.
8 are provided. Radiant heat H from stove 100
Thereby, the nearby air is warmed. The warmed air rises and disperses in all directions near the ceiling 102, and the ceiling 1
After flowing along 02, it descends slowly while cooling (airflow A).

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

[0005] The fan heater 112 has a temperature sensor 122 for detecting room temperature on the back or side of the main body, and has a built-in temperature controller (not shown). The temperature controller operates the heat source 11 so that the room temperature detected by the temperature sensor 122 matches the set temperature.
4 is controlled.

[0006]

However, in the stove 100 shown in FIG. 7, the stove 100 is locally heated in a range (place) where the radiant heat H reaches, but the warmed air rises to the upper part of the room and the ceiling 110 Easy to stay near. For this reason, in the room 102, there is a large temperature difference between the place near the front part of the stove 100 and other places, and the heating efficiency is low.

A fan heater 11 as shown in FIG.
2 is that the hot air blows forward, that is, in the horizontal direction, so that it can be immediately warmed even in a remote place, and is superior to the above-mentioned radiant stove 100 in terms of heat convection. Is also excellent. But,
Locations that are not exposed to warm air, for example, the sides (left and right) and behind the fan heater 112, are difficult to warm up, and the heating efficiency for warming the entire room is still insufficient.
The temperature sensor 1 provided near the air inlet 118
22 is exposed to cold intake air, so that the 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.
In this regard, it is possible to perform temperature compensation, but the error in the measured temperature is too large, and optimal control is difficult.

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

The present invention has been made in view of the above problems, and has as its object to provide a heating device in which the heating efficiency is improved so that the entire room is efficiently warmed, and the comfort and energy consumption efficiency are improved. I do.

And a flow rate adjusting means for adjusting the pressure.

A third heating device according to the present invention, in the first or second heating device, has a structure in which a filter for purifying air is installed in the air passage body.

[0015]

[0016]

[0017]

With the rotation of the fan, air near the floor is sucked into the apparatus through the air suction port. In the apparatus, a part of the air flow is sent to a heat source by an air flow distribution means, where it is heated and discharged outside as hot air from a hot air outlet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows the basic configuration and operation of a floor-standing stove according to an embodiment of the present invention.

The stove 10 of this embodiment is installed or placed on a floor 14 at a desired location in a room 12. The main body of the stove 10 has a heat source 16 of a combustion type or an electric heat type.
And a heat reflecting plate 18 for efficiently radiating the heat generated by the heat source 16 in a predetermined direction, for example, toward the front.

A heat convection promoting unit 20 is integrally or detachably attached to the back of the main body of the stove 10. The heat convection promoting unit 20 includes a tubular air duct 22 attached to the main body in a substantially vertical posture, and a fan 24 provided at a lower portion in the air duct 22.

Both ends of the airway body 22 are open, and an opening 22a at the lower end constitutes an air intake for sucking (taking in) air near the floor 14, and an opening 22b at the upper end.
Constitutes an air outlet for blowing out (exhausting) air. The air inlet 22a and / or the air outlet 22b may be provided with a lid having a large number of through holes, and a dust removing filter or an air cleaning filter may be attached.

The fan 24 may be a fan motor in which a drive motor and a blade are integrated, and an electric cable (not shown)
Air is sucked from the air inlet 22a in a predetermined rotational direction by commercial AC power through the air outlet 22a.
b.

In the stove 10 having such a configuration, the nearby air is warmed by the radiant heat H discharged forward from the heat source 16. The warmed air rises toward the ceiling 26. On the other hand, behind the warm air flow A, the relatively cool air near the floor 14 is generated by the rotation of the fan 24 of the heat convection promoting unit 20, and the air intake port 22 a
The air is sucked or introduced into the airway body 22. The air sucked into the air duct body 22 passes through the fan 24, is sent upward, and is blown out almost immediately to the ceiling 26 from the air outlet 22b.

The ceiling 26, especially the stove 10,
In the vicinity of the ceiling 26 above, the flow A of warm air and the flow C of relatively cool air from the thermal convection promotion unit 20 intersect, and the warm air quickly cools down (dissipates heat) and descends, 14 along the heat convection promoting unit 20
Flows toward the air suction port 22a (airflow D).

As described above, the heat convection promoting unit 20 sends the air near the floor 14 which is relatively hard to warm immediately next to or behind the stove body to the vicinity of the ceiling 26 above the stove 10, thereby promoting the indoor heat convection. Is done. Due to the heat convection promoting action of the heat convection promoting unit 20, the heat generated by the stove 10 reaches all over the room, and the place away from the stove 10 (especially near the floor 14 or the feet) becomes warm. This improves the comfort of indoor heating,
Fuel and power consumption can also be reduced. Moreover, by attaching an air purifying filter to the wind path body 22 of the heat convection promoting unit 20, air purifying can be performed at the same time.

The flow rate (air volume) or flow rate (wind speed) of the air flow C blown from the air outlet 22b of the thermal convection promoting unit 20 can be variably adjusted. For example, the rotation speed of the fan 24 may be variably adjusted.

Further, in order to increase the ascending force of the air flow C and thereby increase the heat convection effect, as shown in FIG. 1, a fan 24 is disposed below the wind path body 22 so that the fan 24 and the air outlet 22b are formed. It is preferable to lengthen the airway distance (blowing approach distance) between them.

Further, as shown in FIG.
The air passage extension 28 may be detachably attached to the upper end of the air passage C, so that the efficiency of raising the air flow C and, consequently, the heat convection effect may be enhanced.

FIG. 3 shows the basic structure and operation of a fan heater according to one embodiment of the present invention. It should be noted that the fan heater 30 of this embodiment also has the same structure as the above-described embodiment.

Nearby air is introduced into the heater from the air inlet 36,
The introduced air passes through the fan 34 and is sent to the heat source 32, where it is heated and then heated as hot air at the hot air outlet 3.
8 is blown forward. The warm air B from the warm air outlet 38 travels straight along the floor 14 for a while, then rises and is dispersed in four directions near the ceiling 26.

A heat convection promoting unit 20 having the same structure and function as the above embodiment is integrally or detachably attached to the back or side surface of the main body of the fan heater 30.
Also in this embodiment, the heat convection promoting unit 20 sucks air near the floor 14 behind the fan heater 30 and blows out the sucked air toward the upper ceiling 26. Thereby, the warm air near the ceiling 26 is mixed with the relatively cool air from the heat convection promoting unit 20, thereby promoting the heat convection in the room, and the heat reaches the side or the rear of the fan heater 30 and The whole is warmed. Therefore, the comfort of indoor heating is improved, and the consumption of fossil fuel or electric power is reduced.

Although the air flow D touched by the temperature sensor 40 at the back of the main body is cooler than the hot air B at the front, the air flow D is warmed to near the average room temperature by the heat convection promoting effect of the heat convection promoting unit 20. Therefore, the temperature sensor 40
