Generally, a fireplace is installed in a living room for an interior purpose that produces a warm and warm atmosphere together with a heating purpose for raising the room temperature.

The fireplace generates soot or smoke when the fuel is burned, and some of them stick to the sight of the opening and closing door to make it impossible to visually confirm the inside of the combustion chamber. In a fireplace according to the related art (Patent Document 1), external air is guided to the upper portion of the combustion chamber through a clean air guide portion to remove soot to be attached to the sight window even during combustion, and external air is sprayed downward toward the window of the opening / .

The clean air injected with the downflow as proposed in Patent Document 1 is heated while being guided from the lower part of the combustion chamber to the upper part and is not blown down to the lower part of the sight window after being blown down from the upper part of the sight window. Also, since the opening and closing door covers the ash together with the combustion chamber, there is a risk of accidents due to careless opening of the door during use of the fireplace.

According to another prior art fireplace (Patent Document 1), the housing space portion 11 formed in the fireplace main body 1 is formed to accommodate the ash receiving portion 9 formed integrally with the ash tray door 3 A plurality of second air holes 13b are formed at positions corresponding to the first air holes 13a at the front upper end portion and a plurality of air exhaust holes 17a are formed at the front lower end portion of the combustion chamber 7 in the upward direction .

The space portion 25 is formed between the second air hole 13b formed in the front upper end portion of the storage space portion 11 formed in the fireplace body 1 and the air discharge hole 17a formed in the front lower end portion of the combustion chamber 7, So that air is directly introduced into the air discharge hole 17a in the second air hole 13b and discharged to the opening and closing door 15 in the combustion chamber 7. [

An air adjusting screw 31 is provided to adjust or shut off the amount of air flowing into the air inflow hole 5 formed in front of the ash tray door 3, The air adjusting screw 31 is made larger than the air inflow hole 5. In this case,

The above-described prior art provides an air flow from the lower end portion to the upper end portion of the sight window, so that there is no problem as in the technique of Patent Document 1. However, the noise due to the air flow generated in the air discharge hole 17a, And the first air hole 13a to the outside of the fireplace, and as a user of the fireplace, there is a problem that the noise of 'bangung ~' is disturbed and the sleep is interrupted.

The first damper 210 is disposed under the plurality of first vent holes 151 and rotates clockwise or counterclockwise to control the inflow amount of the external air to be used as the air curtain. Correspondingly, the second damper 220 is disposed under the plurality of second vent holes 161, and is a component that rotates clockwise or counterclockwise to control the inflow amount of external air to be used for combustion.

As shown, the combustion chamber 130 is defined by a first horizontal plate 12 and a second horizontal plate 13, a left side wall 10a and a rear side 10b and a right side wall 10c of the housing 10 . The inner surface of the combustion chamber 130 except the combustion grill 300 is covered with the refractory material 400.

The combustion chamber 130 has a deflector 500 arranged at an upper side thereof and inclined upwardly from the upper side thereof. The deflector 500 can be fixed on the inner surface of the combustion chamber to change the direction of the airflow. The front edge of the deflector 500 is spaced apart from the front surface of the housing 10 by a predetermined distance to enable natural air circulation inside the combustion chamber 130.

A fireplace (1) according to a preferred embodiment of the present invention is characterized by supplying an air curtain for an opening and closing door in an upward flow. For this purpose, in the present invention, external air is supplied to the lower front side of the combustion chamber 10 separately from the combustion air supply line so that soot generated when fuel (firewood) is burned is attached to the sight window 31 of the door 30 It can be prevented or eliminated. The air curtain generating unit 100 includes a tubular guide tube 110 extending in the first chamber 150 to the lower side of the combustion chamber 130 and extending in the horizontal direction in the lower portion of the combustion chamber 130, The pipe of the guide pipe 110 is disposed laterally on the lower side of the combustion chamber 130 as shown in the figure. The guide pipe 110, specifically the guide pipe 110 arranged in the horizontal direction, has a plurality of discharge holes 111. The air for the air curtain is ejected from the lower inner side of the sight window 31 of the opening and closing door 30 through the plurality of ejection holes 111 and flows to the upper inner side to form an upflow air curtain inside the sight window 31 . 2B, in particular, the discharge hole 111 is disposed under the guide portion 11a of the front panel 11 so that the air for the air curtain, which is discharged to the discharge hole 111, So that it can be supplied to the inner side. The guide portion 11a can be disposed higher than the position of the lowermost end of the opening / closing door 30 that is in contact with the front panel 11 to prevent the outflow of the air for air curtain to the outside. The guide portion 11a is protruded from the front panel 11 as shown in the figure and has a narrowed distance between the window 31 and the opening and closing door 30, 11a of the air curtain. The guide portion 11a can be used as a protrusion preventing the outflow of the ashes remaining inside the combustion chamber.

The discharge hole 111 is a constituent member for spraying the air for the air curtain through the outside of the front panel 11 from the inside of the guide pipe 110 as shown in the figure.

The solid arrows indicate the flow of air for the air curtain. The air for the air curtain flows from the lower end of the rear surface 10b of the housing 10 and moves to the first chamber 150 through the first damper 210. [ The external air introduced into the first damper 210 is supplied from the rear of the lower end of the housing 10. The first chamber 150 provides a space heated by the heat generated in the combustion chamber 130 while temporarily storing the air supplied to the guide pipe 110 on a path communicating with the guide pipe 110. The air for the air curtain is guided to the lower front side of the combustion chamber 130 in the first chamber 150 by means of the guide pipe 110. The air for the air curtain passes through the discharge hole 111 to rapidly set the flow velocity and moves upwards along the inside of the sight window 111 to pass through the air flow path between the upper part of the combustion chamber 130 and the deflector 500, (18).

The dotted arrow indicates the flow of the combustion air. The combustion air flows from the lower end of the rear face 10b of the housing 10 to the second chamber 160 through the second damper 220 and passes through the through hole 16a of the second vertical plate 16 And is guided into the combustion chamber 130 along the slots of the reed receiving compartment 140 and the combustion grill 300.
