Abstract

PURPOSE:To enable to realize both the usages employed with and without a fan and at the same time to obtain favorable combustion state by a structure wherein a blast port is arranged on the double combustion plates of an exhaust hood to guide combustion gas and at the same time the fan is detachably mounted on the back of a casing at the position opposite to the blast port. CONSTITUTION:Heating is performed by the radiation through an opening 10 and by the convection through an blow-off port 3, when the titled device is used under the state that no fan 9 is equipped. When the titled device is used under the state that the fan 9 is equipped, both combustion gas and blast by the fan 9 are discharged through the blow-off port 3, because the upper part of an exhaust hood 4 forms the blast passage. At this time, the combustion gas is sucked due to the blast of the fan 9 so as to produce uniform hot air. Because the blast does not exert adverse effect such as the disturbance of air flow and fluctuation of air pressure upon the combustion chamber in the exhaust hood 4, favorable combustion is realized under both the states that the fan is and is not equipped. In addition, because heat shielding plates 5 and 6 are provided in the exhaust hood 4, the temperature of a casing 1 can be prevented from rising.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a domestic heating device, and relates to heating by radiation and convection.

Conventional configuration and its problems Traditionally, radiant heating devices take radiation from the front, and
Most heaters heated the interior of a room by discharging combustion gas from above and using convection, but this type of heater did not provide uniform temperature distribution within the room, and had drawbacks in terms of comfort and energy saving.

There are fan-equipped stoves and fan heaters that have a fan installed in the stove, but these have a fan built into the appliance and are expensive, so even if a fan is installed that can be easily installed by the person who uses it, there is no need to turn it on. There is a demand for a heating device that can be used for

Purpose of the Invention The present invention provides a heating device in which the blower can be easily attached and detached, can be used depending on the user's preferences, and can provide good combustion conditions with or without the blower turned on. It is.

Structure of the Invention The present invention includes a burner provided in a casing, and an exhaust hood that covers the burner to form a combustion chamber and guides combustion gas to an outlet at the upper front surface of the casing. The exhaust hood is provided with double heat shield plates A and B, and the heat shield plate A is provided with an air outlet. Moreover, the blower is detachably attached to the back side of the casing facing the air outlet of the heat shield plate A.

With this configuration, when the blower is installed, the hood above the outlet and the heat shields A and B become a hot air passage, and when the blower is not installed, the heat shields A and B prevent the temperature of the casing from rising. There is.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a front view of this embodiment, and FIG. 2 is a side sectional view.

A burner 2 is provided at the bottom of the casing 1, and a hood 4 is provided to cover the burner 2 and guide a combustion chamber and exhaust gas to an outlet 3 at the upper front surface of the casing 1. A heat shield plate B6 is provided above the hood 4 so that the heat shield plate A5 covers the hood. A blower lower is provided at the rear of the heat shield plate A5, and the blower 9 is configured to be easily attached to and removed from a position on the casing back surface 8 facing the blower lower.

An opening 10 for receiving radiation is provided on the front surface of the casing 1 facing the red-hot combustion surface of the burner 2.

When used without the blower 9, heating is achieved by radiation from the opening 10 and convection from the air outlet 3.

When the blower 9 is provided, the combustion gas and the air blown by the blower 9 are discharged from the outlet 3 because the upper part of the hike hood 4 through which the combustion gas is introduced is a ventilation passage. At this time, the combustion gas is sucked in by the blower 9 and becomes uniform warm air, which is blown into the room, so the temperature distribution in the room is good.
Comfortable heating and energy savings are achieved.

Furthermore, since the air blown into the combustion chamber in the exhaust hood 4 does not have any adverse effects on combustion such as turbulence of airflow or fluctuations in pressure, good combustion can be achieved both with and without the blower.

Furthermore, the exhaust hood 4 has a heat shield plate A5. Since B6 is provided, it is possible to prevent the temperature of the casing 1 from rising, and even if the dimension between the exhaust hood 4 and the casing 1 is shortened, the temperature of the casing 1 is prevented from rising by 5 pages, making it a compact heating device. It looks like it can be done.

Effects of the Invention As explained above, the present invention has a structure in which the blower can be easily attached and detached from the back of the casing, and can be used with or without the blower depending on preference. We can provide radiant and convection heating systems.

Furthermore, since the combustion condition hardly changes even if the blower is turned on or off, a stable and good combustion condition can always be obtained.
