Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heaters, and in particular relates to a door-opening smoke prevention structure for a heater. Background Art
[0002] A heater, such as a real fire heater, is a heater in which open flames are burned by burning fuel (such as wood, charcoal, etc.) in the combustion chamber. Its structure generally includes a furnace body 1, a combustion chamber 2, an ash storage chamber 3, a furnace door 4 and an external smoke exhaust channel 5. The furnace door 4 is generally used to add fuel (such as wood, charcoal, etc.). A front smoke exhaust connection channel is provided between the combustion chamber 2 and the ash storage chamber 3, that is, the smoke exhaust connection channel is arranged on the front side, and the furnace door is generally also arranged on the front side. This structure has a disadvantage. Since the smoke exhaust connection channel is arranged on the front side, when the furnace door is opened, some smoke and dust can easily float out, especially for the hinged furnace door 4. This situation is particularly obvious. How to avoid or reduce the occurrence of this situation is what we need to solve urgently. Utility Model Content
[0003] The utility model provides a door-opening smoke prevention structure for a heater, which can solve the problems pointed out in the background technology.
[0004] A stove door opening smoke prevention structure includes a stove body, wherein the stove body includes a stove body, a combustion chamber, an ash storage chamber, a stove door and an external smoke exhaust channel. A rear smoke exhaust connection channel is provided between the combustion chamber and the ash storage chamber, and the stove door is arranged on the front side of the stove body.
[0005] Preferably, an ash removal opening is provided on the front side of the ash storage chamber, and a cover plate is detachably connected to the ash removal opening.
[0006] Preferably, the ash storage chamber has a curved smoke exhaust channel.
[0007] Preferably, the curved smoke exhaust channel is an "S"-shaped curved smoke exhaust channel.
[0008] Preferably, a front low baffle and a rear high baffle are provided in the ash storage chamber, and the rear high baffle is located between the external smoke exhaust channel and the rear smoke exhaust connecting channel, thereby forming an "S"-shaped bent smoke exhaust channel.
[0009] Preferably, the front low baffle and the rear high baffle are both arranged to be tilted downward from back to front.
[0010] Beneficial effect: The utility model provides a stove door opening anti-smoke structure, which is provided with a rear smoke exhaust connection channel so that it is arranged opposite to the front side stove door, which can effectively avoid or reduce the exhaust of smoke when the door is opened, is convenient for users to use, improves user experience and improves product quality;
[0011] In addition, a front ash removal port is provided to facilitate ash removal operations;
[0012] A curved smoke exhaust channel is provided inside the ash storage chamber to improve combustion efficiency, enable more complete combustion, and prevent dust from falling into the ash storage chamber. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0018] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.
[0019] Example 1:
[0020] like Figure 1-3 As shown, an embodiment of the present invention provides a door-opening smoke prevention structure for a heater, comprising a heater body, wherein the heater body comprises a furnace body 1, a combustion chamber 2, an ash storage chamber 3, a furnace door 4 and an external smoke exhaust channel 5, a rear smoke exhaust connection channel 6 is provided between the combustion chamber 2 and the ash storage chamber 3, and the furnace door 4 is arranged on the front side of the furnace body 1.
[0021] In some embodiments, an ash removal opening 7 is provided on the front side of the ash storage chamber 3 , and a cover plate 8 is detachably connected to the ash removal opening 7 , and the detachable connection can be achieved by using a plurality of bolts.
[0022] Example 2:
[0023] The ash storage chamber 3 has a curved smoke exhaust channel 9 therein.
[0024] Specifically, the curved smoke exhaust channel 9 is an "S"-shaped curved smoke exhaust channel, and a front low baffle 31 and a rear high baffle 32 are provided in the ash storage chamber 3. The rear high baffle 32 is between the external smoke exhaust channel 5 and the rear smoke exhaust connecting channel 6, thereby forming an "S"-shaped curved smoke exhaust channel. The "S"-shaped curved smoke exhaust channel increases the discharge length, the combustion time and the contact time with oxygen, thereby improving the combustion efficiency and making it burn as fully as possible to obtain more calorific value.
[0025] In some embodiments, the front low baffle 31 and the rear high baffle 32 are both tilted downward from back to front, so that smoke and dust can be easily concentrated at the front ash removal port 7 as much as possible, facilitating the ash removal operation.
[0026] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
