BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas fireplace, and more particularly, to a gas fireplace which can prevent odors and soot generated when a solid fuel such as coal or firewood is used from entering the room, will be.

Generally, a fireplace is installed in a room of a human residence such as a wooden building, a pension or a villa. The installed fireplace is heated by heating the solid fuel such as wood or coal, and is used as an interior decoration to decorate the interior. However, solid fuels used in fireplaces do not burn completely. Accordingly, odor, dust, soot and smoke can not be discharged to the outside, and the glass remains in the combustion chamber, thereby smearing the glass of the door. In case of seriousness, smell or smoke may enter the room and contaminate the room air. To prevent this, gas is used instead of solid fuel.

Conventionally, Korean Registered Utility Model Registration No. 20-0207505 (name of design gas fireplace) of Korean Registered Trademark includes a lower body having an air inlet formed therein, an upper body provided with a burner connected to the inside of the firebox, A communicating tube connected to an upper portion of the upper body and provided with a heat dispersing shade at an end thereof, and a model firewood installed on the upper portion of the burner.

However, the conventional gas fireplace is a structure in which a fireplace is opened. Therefore, the odor generated when the gas is burned in the burner and the soot are directly introduced into the room through the open hearth, thereby polluting the room air. Inhalation of contaminated indoor air has a problem of causing harmful effects on the human body such as dizziness, dyspnea and respiratory diseases.

Further, the burner is installed in the lower part of the bottom plate provided inside the upper body, so that the flame of the burner is diffused into the model mounting placed on the top of the bottom plate while heating the bottom plate. Therefore, the flame of the burner is not dynamic because the bottom plate, which occupies a large area, is first heated and then diffused into the model firewood, and the heat cost is increased due to the increase of the gas consumption because of the heat loss.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gas fireplace of a new structure capable of solving the problems of the conventional gas fireplace. It is an object of the present invention to provide a gas fireplace which can open and close a door in an open fireplace to prevent odors, dust, soot, and smoke, which are harmful to a human body, .

Another object of the present invention is to provide a gas fireplace which can reduce the fuel cost because the outside air is introduced from various directions such as the bottom and side of the furnace stand, the flame of the combustion chamber is very dynamic, .

A gas fireplace according to the present invention includes: a main body having a combustion chamber having a crater on one side thereof, an air inlet and an air outlet communicating with the combustion chamber on the other side; A door provided on the front face of the crater so as to be openable and closable; And a burner assembly mounted on a bottom plate of the combustion chamber, wherein the burner assembly has a plurality of discharge holes through which air and gas pass, at one end of the burner assembly having a space formed therein and facing the combustion chamber, A furnace having a connecting pipe for the furnace; A nozzle having one end inserted into the connection pipe and injecting gas introduced from the outside; And a valve installed at the lower portion of the main body for interrupting the flow of the gas connected to the other end of the nozzle and supplied to the combustion chamber.

According to the present invention, a door that can be opened and closed in an open fire wall is provided to block odor, dust, soot, smoke, and the like, which are generated when the gas is burned, from entering the room. Therefore, it is possible to prevent diseases which are harmful to the human body such as dizziness, difficulty in breathing and respiratory diseases due to inhaling uncontaminated indoor air.

Also, since the outside air is supplied in a large amount in many directions such as the bottom and side of the furnace stand, the flame is very dynamic. Therefore, it is possible to create aesthetic appearance of the flame shape of the combustion chamber while harmonizing with the ceramic charcoal and artificial ceramic firewood placed on the upper part of the burner stand, so that the visual effect is excellent.

In addition, the furnace stand is installed in an exposed state on the bottom plate of the combustion chamber. Therefore, since the flame does not heat the bottom plate, the heat loss is small, and the gas consumption can be reduced, thereby reducing the fuel cost.

When the valve 163 is rotated clockwise, The gas supplied to the combustion chamber 111 is blocked. The gas automotive short-term 165 may be installed between the valve 162 and the gas supply pipe 164 as occasion demands.

Referring to FIGS. 3 and 4, the ignition plug 166 is mounted at one end of the furnace bed 151, and is preferably provided at a position adjacent to the plurality of the discharge holes 153. The spark plug 166 thus installed operates by rotating the lever 163. That is, the lever 163 is rotated to apply a shock to the piezoelectric element, and a high voltage current generated in the piezoelectric element is sparked to an upper portion adjacent to the discharge hole 153 on the electric wire. Then, the gas mixed with the air introduced into the plurality of discharge holes 153 is ignited.

A specific operating state of the gas fireplace 100 according to the present invention will be described.

First, the first door 120 is opened, and ceramic charcoal and artificial ceramic firewood are placed on one end of an arc furnace 151 located in the combustion chamber 111. The valve 162 is opened by turning the lever 163 provided in the lower part of the front surface of the main body 110 in the counterclockwise direction. The gas supplied to the gas supply pipe 164 is injected into the nozzle 159 through the valve 162. [ At this time, outside air flows into the other end of the connection pipe 154 into which the nozzle 159 is inserted through the lower air passage 115 formed at the lower part of the rear surface of the main body 110. The air injected from the nozzle 159 and the air introduced into the lower air passage 115 are mixed so that the plurality of discharge holes 153 are formed through the holes 154a formed at one end of the coupling pipe 154 And flows into the inner space 152 of the furnace bed 151. A gas mixture of air and gas passes through the plurality of discharge holes 153 and is supplied toward the combustion chamber 111.

The external air introduced through the air inlet 115 formed at the bottom of the rear surface of the main body 110 passes through the air passage 112a of the bottom plate 112 and a plurality of air passages 156, and flows in the direction of the combustion chamber 111 through the air supply pipe 157. Apart from the air mixed with the gas and the gas flowing into the plurality of discharge holes 153, the outside air flows through the air passage 112a of the bottom plate 112 and the plurality of air passages 156 of the furnace bed 151 A large amount of air flows into the combustion chamber 111.

Next, when the lever 163 is turned endlessly, an impact is applied to the piezoelectric element, and a spark is generated in the spark plug 166 provided at the upper end of one end of the furnace bed 151 adjacent to the discharge hole 153. The spark ignites the gas mixed with the air supplied to the combustion chamber 111 through the plurality of discharge holes 153. At this time, a large amount of outside air introduced into the combustion chamber 111 through the plurality of air passageways 156 can produce a flame of the combustion chamber 111 in a dynamic and aesthetic manner.

Next, the amount of air to be mixed with the gas injected from the nozzle 159 can be adjusted by turning the throttle plate 161. That is, when the distance between the distal end of the connection pipe 154 and the throttle plate 161 is widened and the throttle plate 161 is adjusted, the outside air is largely introduced into the connection pipe 154 and the distal end of the connection pipe 154 and the throttle plate 161 The external air is introduced into the connection pipe 154 in a small amount. In this way, the flame shape can be more aesthetically directed by adjusting the outside air to be mixed with the gas.

The high temperature heat of the combustion chamber 111 is blocked by the partition wall 155 formed in the internal space 152 of the furnace bed 151 in the gas fireplace 100 according to the present invention. And is installed in the main body 110 and is secondly cut off by the train suspension chamber 118. The valve 162, the lever 163, and the valve 163 provided at the lower part of the furnace stand 151 are disposed in the lower portion of the furnace stand 151 to shut down the high temperature heat of the combustion chamber 111 in the downward direction of the furnace stand 151 It is possible to prevent malfunctions or damages of the components such as the gas automotive unit 165 and the like.

The gas fireplace according to the present invention may automatically open or close a valve or operate a spark plug in conjunction with a sensor for sensing a room temperature. That is, if the room temperature is higher than the set temperature, the sensor senses and automatically closes the valve. If the room temperature is lower than the set temperature, the valve is automatically opened and ignited. In addition, when the indoor power is turned off or the combustion chamber is turned off, the valve may automatically shut off to prevent accidents caused by gas leakage.
