Abstract

PURPOSE:To provide a radiation type heating machine capable of improving heating capacity at the time of local heating to a warmth taking person and having both functions of local heating and the whole heating. CONSTITUTION:A surface-shaped radiation type heater 2, on the whole surface of which a radiating surface is arranged, is installed to a main body 1, a supply opening 3 is formed to the upper section of the whole surface of the main body 1 and a suction opening 4 to the lower section of the rear of the main body 1, and a section between the supply opening 3 and the suction opening 4 is communicated to form a ventilation flue 5. A blasting device 6 is mounted into the ventilation flue 5, an operating section 8 conduction-controlling the surface-shaped radiation type heater 2 and the blasting device 6 is set up to the top face of the main body 1, and local heating and the whole heating can be changed over by the operating section 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric heating type radiant heater.

[0002]

2. Description of the Related Art Generally, a radiant heater is used which heats a planar heater having a heater wire embedded therein to dissipate radiant heat.

Conventionally, this type of radiant heater has a structure as shown in FIG. As shown in the figure, a planar heater 102 having a heater wire embedded inside a main body 101 is provided, and when the planar heater 102 is energized, radiant heat is directly radiated to a warmer in front to heat the warmer. It was possible to heat the air to generate an updraft, and circulate the air inside the room to heat the entire room.

[0004]

In such a conventional radiant heater, the radiant heat and the convective heat can be utilized at the same time, but the radiant heat from the planar heater is not necessary for the warmer to directly warm the radiant heat. There was a problem of lacking.

A hot air heater using a ceramic heater is effective for local heating, but has a problem that it is not suitable for heating the entire room.

The present invention solves the above problems, and provides a radiant heater that can improve the heating capacity of a warmer during local heating and that has both local heating and general heating functions. To aim.

[0007]

In order to achieve the above object, the present invention provides a planar radiation type heater provided on the front surface of a main body,
An air passage provided behind the radiant heater, an air blower provided in the air passage, and an air outlet communicating with the air passage above the radiant heater, and the radiant heater is energized. It is configured such that the blower device is energized and controlled.

[0008]

According to the present invention, with the above structure, the air from the air blower provided at the rear portion of the planar radiant heater is immersed in the guide plate and is guided forward from the upper portion of the planar radiant heater. The upward airflow warmed around the radiant heater can be discharged as warm air heat in the direction of the warmer without letting it escape upward, and due to the synergistic effect with the radiant heat from the planar radiant heater, The heating capacity can be increased. Further, the blower can be controlled to be turned ON / OFF while the planar radiant heater is energized by operating the operation unit.

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

As shown in the figure, a planar radiant heater 2 is attached to a main body 1, and a radiation surface is arranged on the front surface of the main body. Air outlet 3 on the upper front of the body 1 and suction 4 on the lower rear of the body 1
Is provided, the air outlet 5 and the suction inlet 4 are communicated with each other to form a ventilation passage 5, and the ventilation device 5 is provided in the ventilation passage 5. The ventilation path 5 is provided along the back surface of the planar radiant heater 2. A guide plate 7 is provided above the planar radiant heater 2 to guide the blowing direction forward, and an operation unit 8 for controlling the energization of the planar radiant heater 2 and the blower 6 is provided on the top surface of the main body 1.
Is equipped with. It should be noted that the planar radiant heater 2 is operated by the operation unit 8.
In the energized state, only the blower device 6 has a circuit configuration capable of individually controlling energization.

In the above structure, at the time of local heating, the planar radiant heater 2 and the air blower 6 are energized by the operation portion 8 to discharge convective heat as warm air in addition to radiant heat dissipation. As a result, the heating amount for the warmer can be increased and the heating effect can be enhanced.

Next, at the time of heating the room, the air blower 6 is deenergized and only the planar radiant heater 2 is energized so that the radiant heating to the warmer and the heating of the entire room by convection can be performed simultaneously. it can.

As described above, according to the present embodiment, the ventilation passage is provided on the back surface of the planar radiant heater, and the heat flow rising from the planar radiant heater is directed to the warmer by the air blower in the ventilation passage. In addition to enhancing the effect as local heating by blowing air to the room, radiant heating and general heating can be performed at the same time when the air blower is stopped. Can be used properly.

[0014]

As is apparent from the above embodiments, according to the present invention, in addition to the radiant heat of the planar radiant heater, a hot air flow rising by blowing air from the upper part of the planar radiant heater is collected. It is possible to enhance the effect of local heating by discharging in the direction of the user, and by controlling the operation of the blower while the planar radiant heater is energized by the operation unit, it is possible to match the usage of local heating or general heating. It is possible to provide a radiant heater that can be used properly according to the circumstances.
