Description

Technical Field

[0001] The utility model relates to the technical field of gas heating furnaces, and particularly to a flame observation structure of a gas heating furnace. Background Art

[0002] Chinese Patent No. ZL201921813737.X discloses a gas heating and hot water furnace that is convenient for observation, which includes a furnace body and a combustion chamber disposed inside the furnace body. An observation window is opened on the furnace body corresponding to the position of the combustion chamber, and a sealed observation sleeve is clamped on the observation window. The material of the sealed observation sleeve is a transparent high-temperature resistant nylon material; the sealed observation sleeve is disposed on the rear cover of the furnace body through the observation window; the sealed observation sleeve includes a transparent observation part and a clamping part located on the peripheral side of the transparent observation part. A clamping groove is opened on the outer side of the clamping part, and the clamping groove is clamped with the rear cover.

[0003] The sealed observation sleeve is installed on the rear cover of the furnace body. If the installation space of the user is too small, the sealed observation sleeve on the rear cover is not convenient for the user to observe, and a relatively thick pull ring is provided on the sealed observation sleeve. The material consumption of the product increases, resulting in an increase in cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flame observation structure of a gas heating furnace, which is convenient for the user to observe the flame generated on the burner by providing flame observation parts on both the furnace body and the combustion chamber.

[0005] The purpose of the utility model is realized as follows:

[0006] A flame observation structure of a gas heating furnace includes a furnace body and a combustion chamber disposed inside the furnace body. A first flame observation part is provided on the combustion chamber corresponding to the flame generation position of the burner, and a second flame observation part is provided on the furnace body corresponding to the first flame observation part; the flame generated on the burner of the combustion chamber is observed through the first flame observation part and the second flame observation part.

[0007] The furnace body includes a front panel or a rear cover. An installation part for installing the second flame observation part is provided on the front panel or the rear cover. The second flame observation part is positioned and installed on the front panel or the rear cover of the furnace body through the installation part; the installation part is flush with the front surface of the front panel or the rear cover, or the installation part protrudes from the front panel or the rear cover. The outer edge of the second flame observation part abuts against the furnace body and forms a seal.

[0008] A clamping groove part is provided on the second flame observation part, and the second flame observation part is detachably installed on the furnace body through the clamping groove part.

[0009] A plug-in part is provided on the second flame observation part, and the second flame observation part is detachably installed on the furnace body through the plug-in part.

[0010] A light-transmitting position for observing the flame is provided on the second flame observation part.

[0011] The light-transmitting position is circular, oval or polygonal.

[0012] The second flame observation part includes a positioning part and a transparent part. The positioning part is detachably installed on the furnace body, and the transparent part is detachably installed on the positioning part, which is beneficial to reducing the transparent material of the second flame observation part. The positioning part can use an opaque material with a long service life and low cost, while the transparent part can use a transparent material with a low cost, thereby reducing the material cost. When the transparent material of the second flame observation part ages, only the transparent material needs to be replaced;

[0013] Alternatively, the transparent part and the positioning part are integrally formed into a second flame observation part by injection molding, reducing the assembly steps.

[0014] The furnace body includes a front panel or a rear cover for installing the second flame observation part. A boss part is provided on the front panel or the rear cover, and the boss part protrudes towards the outer end of the front surface of the front panel or the rear cover. The second flame observation part is installed on the boss part, so that the second flame observation part is installed in a position away from the combustion chamber, which is beneficial to avoiding the second flame observation part from absorbing too much heat from the combustion chamber and increasing the distance between the second flame observation part and the combustion chamber.

[0015] A guiding surface is provided on the boss part. The guiding surface is a guiding inclined surface or a guiding arc surface. The second flame observation part is installed on the boss part, and there is a gap between the second flame observation part and the guiding surface to form a removal gap for removing the second flame observation part. There is no need to set structures such as a pull ring on the second flame observation part, which is convenient for the user to reach into the removal gap with the hand to remove the second flame observation part outside the furnace body.

[0016] Insertion pieces for positioning and installing on the furnace body frame are provided on the front panel; or, the front panel is rotatably connected to the furnace body frame.

[0017] The beneficial effects of the present utility model are as follows:

[0018] By providing flame observation parts on both the furnace body and the combustion chamber, it is convenient for the user to observe the flame generated on the burner and the gas combustion situation in the combustion chamber, making the use safer. Description of the Drawings
