Abstract

PURPOSE:To make it possible to use the subjected heater equipped with a radiation type electric heater as a hot air heater even when said heater is used, by making operational a circulation blower which blows air from a hot air outlet during the application of electricity to said heater. CONSTITUTION:Only a selection switch 15 is turned on during heating operation based on petroleum combustion. Then, combustion gas of a burner is burnt in a combustion cylinder. The gas is mixed with cold air blown from a circulation blower 5 in operation, and blown out indoors from a hot air blow down port. When ventilation is unavailable when sleeping, the selection switch 15 is turned off while a selection switch 14 is turned on so as to change over to a radiation type electric heater 9. In this case, a selection switch 16 is also turned on, which makes it possible to circulate indoor air even when the radiation type electric heater 9 is used so that all the interior of a room can be heated with the radiation heat by the radiation type electric heater 9. In this manner, ventilation or noise-related troubles can be eliminated, thereby providing safe and clean heating.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an indoor open oil hot air heater that can use electricity as well as oil as a heat source.

[Conventional technology]

A conventional indoor open oil hot air heater has a structure as shown in FIGS. 3 and 4.

In Fig. 3, 1 is a main body case, 2 is a combustor provided in the main body case 1, 3 is a combustion tube surrounding the combustor 2, 4 is a combustion chamber in the upper part, and 5 is a rear wall of the main body case 1. A blower for indoor air circulation is provided, 6 is provided on the front panel 7 of the main body case 1, and a hot air outlet is communicated with the combustion chamber 4, 8 is a bottom plate, and 9 is located directly below the hot air outlet 6 of the front panel 7. A radiant electric heater is attached to the front panel 7, 10 is a reflector at the rear thereof, and 11 is a front card.

FIG. 4 is its electrical circuit diagram, and 12 is a combustion control circuit;
13 is a changeover switch.

Next, the operation of this conventional device will be explained.

First, when the changeover switch 13 is connected to the terminal (a) side and heating is performed by oil combustion, the combustion gas in the combustor 2 passes through the combustion tube 3, and the indoor air is circulated by combustion''!f, 4. It is mixed with cold air sent from a commercial blower 5 to become warm air at an appropriate temperature, and is discharged into the frying room through a hot air outlet 6 provided on a front panel 7 to heat the room.

The combustion gas in the combustor 2 becomes warm air and is discharged into the room from the flat air outlet 6 as described above.

Therefore, when the heater is running, the indoor air becomes polluted.
Ventilation is sometimes required to supply fresh air into the room. However, this ventilation is not possible while sleeping, so before going to bed, switch the changeover switch 13 to the contact (b) side and switch the heating operation to the radiant air heater 9 installed in front of the front I panel 7. ing. That is, using indoor air to burn oil and releasing it into the indoor circulating air.
At the same time, radiant electric heaters provided local heating using only radiation.

[Problem to be solved by the invention]

Conventional indoor open type kerosene heaters are used as described above, so it is necessary to occasionally ventilate the room during use to bring in fresh air, and radiant electric heaters only heat the room by collecting heat. had the inconvenience of not being usable. This invention aims to eliminate such inconvenience.

[Means to solve the problem]

In this invention, a radiant type M air heater is attached to the front panel part of a main body case provided with a hot air outlet so as to be located near the hot air outlet LH, and when the radiant electric heater is used, A blower for indoor air circulation can be operated to blow air from the hot air outlet.

[Effect]

The device of this invention is normally used as an oil hot air heater with low running costs, but when going to bed or when the oil runs out, it can be used by switching to the pre-installed radiant hot air heater. If the indoor air circulation blower is operated when using the type electric heater, air will be blown from the hot air outlet, so it can be used as a hot air heater.

〔Example〕

An embodiment of the present invention will be described below.

That is, in FIG. 1, 1 is the main case, 2 is the combustor, 3 is the combustion tube surrounding the combustor 2, 4 is the combustion chamber in the upper part of the outside, and 5 is the indoor air provided on the rear wall of the main case 1. A circulation blower 6 is provided on the front panel 7 of the main body case 1,
A hot air outlet communicating with the combustion chamber 4, 8 a bottom plate, 9 a radiant electric heater attached to the front panel 7 so as to be located directly below the hot air outlet 6 of the front panel 7, and 10 a rear 11 is a front guard.

FIG. 2 is its electrical circuit diagram, and 12 is a combustion control circuit;
14, 15, and 1B are selection switches, respectively.

Next, the operation of this invention will be explained.

First, during heating operation by oil combustion, select switch 15
Turn ON only. The combustion gas in the combustor 2 passes through the combustion tube 3 as in the conventional one, mixes with the cold air sent from the indoor air circulation blower 05 in the combustion chamber 4, becomes warm air at an appropriate temperature, and is heated to the front panel. 7 (The warm air is discharged into the room from the provided hot air outlet 6, heating the room.

The combustion gas in the combustor 2 is discharged into the room as warm air through the hot air outlet 6 as described above.

Therefore, since the indoor air becomes polluted during heating, ventilation is sometimes required to supply fresh air into the room. Therefore, when ventilation is not possible, such as while sleeping, the selection switch 15 is set to 0FFL, and the selection switch 14 is set to ONI to switch the heating operation to the radiant electric heater 9 provided on the front of the front panel 7 before going to bed.

At this time, if the selection switch 1B is further set to ONt, the indoor air circulation fan 5 will be operated even when the radiant electric heater 9 is used, and air will be blown from the hot air outlet 6 to radiate the radiant electric heater 9. The radiant heat obtained by the electric heater S spreads throughout the room and can also heat the room.

〔Effect of the invention〕

The indoor open type oil hot air heater of this invention is configured so that the blower for indoor air circulation can be operated even when a radiant electric heater like Shigeko is used, so it can be used as a hot air heater and provides ventilation. Safe and lean heating is possible without worrying about heat or noise. Furthermore, it has the advantage that a rapid heating effect can be expected when used without blowing air.
