Description

Technical Field

[0001] The present invention relates to a detachable filter system, and more particularly, to a detachable filter system in which a filter portion is detachably coupled to an air supply portion provided in a boiler. Background Art

[0002] Generally speaking, gas-fired boilers use gas as fuel and water as a heat medium for heating. Hot water boilers, on the other hand, circulate heating water through a three-way valve within the boiler, indirectly heating the feed water through heat exchange, thus also allowing for hot water use. Gas-fired boilers are installed in various buildings, such as homes, offices, and factories, to supply hot or heating water. They can be categorized as standard boilers and condensing boilers based on whether condensate is generated, and as instantaneous boilers and storage boilers based on the hot water supply method.

[0003] The basic structure of this gas boiler consists of a combustion unit and a heat exchanger within a shell. The combustion unit is the space where the fuel, or gas, burns in the form of a free flame of appropriate length. The combustion gas exhausted from the combustion unit then exchanges heat with the heat medium in the heat exchanger before being discharged through the chimney.

[0004] Furthermore, to maintain a constant combustion efficiency within the combustion device, the fuel-air ratio must be kept constant. To achieve this, air must be constantly supplied from the outside to the air supply port of the housing, and this air must be free of contaminants such as dust. If contaminants contained in the air supplied to the air supply port are delivered intact to the combustion device, the fuel-air ratio will fluctuate randomly, making it impossible to properly adjust the gas-air mixture ratio and prevent proper combustion, leading to reduced heat exchange efficiency.

[0005] To solve the above-mentioned problem, referring to Korean Patent Gazette No. 10-1902455, a boiler air supply filter is proposed, in which a filter unit is provided around the air supply port of the boiler casing, so that the external air flows into the casing after being filtered, thereby filtering foreign matter contained in the air flowing into the interior of the casing through the boiler air supply port, and supplying the air required for boiler combustion in a quantitative manner.

[0006] However, for the air supply port filter of this existing boiler, when the filter unit filters foreign matter exceeding the allowable value, the filter unit will be completely blocked over time, so that the necessary amount of air required for combustion cannot be provided to the combustion device, causing the combustion device to suffer from incomplete combustion or flash back. Summary of the Invention

[0037] Hereinafter, a detachable filter system according to a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

[0038] Figure 1 This is a diagram showing a state where a detachable filter system according to a preferred embodiment of the present invention is installed in a boiler. Figure 2 A schematic diagram showing a detachable filter system in a separated state according to a preferred embodiment of the present invention is shown. Figure 3 It is a cross-sectional view showing an air supply portion of a detachable filter system according to a preferred embodiment of the present invention.

[0039] Reference Figures 1 to 3 According to a preferred embodiment of the present invention, the detachable filter system 100 can easily replace the filter part 130 by detachably combining the filter part 130 to the air supply part 110 provided in the boiler 50. The above-mentioned detachable filter system includes a through-portion 110a, a protrusion 120, a filter part 130 and a sealing part 140.

[0040] The boiler 50 has a conventional structure in which various components such as a combustion device (not shown) and a heat exchanger (not shown) are provided inside a casing 52 formed in a substantially hexahedral shape.

[0041] An air supply unit 110 and an exhaust unit (not shown) are provided at the upper portion of the housing 52. Air is supplied to the interior of the housing through the air supply unit 110, and the air in the housing is exhausted to the outside through the exhaust unit. For example, the air supply unit 110 is formed in a cylindrical shape, and the through-hole 110a is formed along one side of the outer periphery of the air supply unit 110.

[0042] The protrusion 120 is formed to protrude from one side of the outer periphery of the air supply portion 110, specifically, to protrude outward from the outer edge of the through portion 110a. The protrusion 120 has an empty space formed therein. One side of the protrusion 120 is formed to be integrally connected to the through portion 110a, and the other side of the protrusion 120 has an insertion hole 120a formed therethrough.

[0043] Furthermore, a guide groove 112 may be formed on one side of the inner periphery of the air supply portion 110, opposite the protrusion 120. The guide groove 112 is formed as a recessed portion along one side of the inner periphery of the air supply portion 110. Both sides of the guide groove 112 are extended in the direction of the protrusion 120, so that both sides of the guide groove 112 are located facing the protrusion 120.

[0044] The filter portion 130 is detachably coupled to the air supply portion 110, and the filter portion 130 includes a support portion 132, a handle portion 134, and a filter 136. One side of the support portion 132 is formed in a circular shape so as to cover the interior of the air supply portion 110, and the other side is formed so as to be placed inside the protrusion 120. A guide hole 132a is formed in the center of one side of the support portion 132. The handle portion 134 is integrally connected to the outer side of the support portion 132, and is formed in a plate shape so as to cover the guide hole 132a. When the handle portion 134 is located in a position covering the guide hole 132a, the handle portion 134 can also cover the through portion 110a facing the guide hole 132a. In addition, a pair of guide protrusions 134a are formed on both sides of the outer surface of the handle portion 134 located in the opposite direction of the support portion 132. The guide protrusion 134 a is formed to protrude in an outer direction of the guide hole 132 a so that a user can easily grasp the guide protrusion 134 a with a hand.

[0045] For example, filter 136 can be formed in a grid shape, allowing air to pass through while blocking foreign matter. Filter 136 is recessed downward and may include a flat portion 136a, spaced apart from guide hole 132a and positioned below guide hole 132a. A connecting portion 136b, extending from the outer periphery of the flat portion along the inner periphery of guide hole 132a, connects the outer periphery of flat portion 136a to the inner periphery of guide hole 132a. An accommodating space 136c is provided between flat portion 136a and connecting portion 136b.

[0046] The sealing portion 140 is a conventional structure located between the handle portion 134 and the insertion hole 120 a to form a sealed state between the handle portion 134 and the insertion hole 120 a when the handle portion 134 covers the insertion hole 120 a .

[0047] Figure 4 This is a cross-sectional view showing a state in which the filter portion of the detachable filter system according to a preferred embodiment of the present invention is inserted into the air supply portion along the protrusion. Figure 5 This is a schematic diagram showing a state in which the filter portion of a detachable filter system according to a preferred embodiment of the present invention is coupled to the air supply portion. Figure 6 A cross-sectional view illustrating a state in which a filter portion of a detachable filter system according to a preferred embodiment of the present invention is coupled to an air supply portion.

[0048] Reference Figures 4 to 6 , the process of combining the filter part 130 with the air supply part 110 will be described. First, the support part 132 is inserted into the inside of the protrusion 120 through the insertion hole 120a. At this time, the support part 132 is guided along the bottom surface of the inside of the protrusion 120, so that the support part 132 slides steadily along the bottom surface of the protrusion 120 in the inside of the protrusion 120 toward the air supply part 110 without shaking. Afterwards, the support part 132 is inserted into the inside of the air supply part 110 through the through part 110a. At this time, the outer peripheral edge of the support part 132 slides steadily along the direction of the air supply part 110 in a state of being inserted into the guide groove 112. As described above, when the support part 132 of the filter part 130 is inserted into the air supply part 110, the support part 132 is steadily inserted into the air supply part 110 in a state of being guided by the protrusion 120 and the guide groove 112.

[0049] When support portion 132 is inserted into air supply portion 110, filter 136 located in support portion 132 filters various pollutants contained in the air supplied by air supply portion 110. Furthermore, as filter 136 filters pollutants from the air, the pollutants accumulate in accommodation space 136c of filter 136. Because filter 136 provides a space for pollutants to accumulate, when filter portion 130 is removed from air supply portion 110, the pollutants filtered out by filter 136 do not remain in air supply portion 110 but are easily moved to the outside.

[0050] Furthermore, when the support portion 132 is inserted into the air supply unit 110, the handle portion 134 covers the insertion hole 120a. At this point, first bolted portions 122 are formed on either side of the insertion hole 120a, and second bolted portions 134b are formed on either side of the handle portion 134. These second bolted portions 134b cover the first bolted portions 122. Furthermore, bolts B are detachably connected to the second bolted portions 134b and the first bolted portions 122. Because the handle portion is detachably connected to the insertion hole 120a, if a large amount of contaminants accumulate in the filter 136, the bolts B can be disengaged and the handle portion 134 removed externally. This allows the support portion 132 to detach from the air supply unit 110, allowing the entire filter unit 130 to be removed from the air supply unit 110. A new filter unit 130 can then be attached to the air supply unit 110, or the existing filter unit 130 can be reused after removing any remaining contaminants from the filter 136.

[0051] Although the present invention has been described in detail in the above embodiments, the present invention is not limited thereto. It is obvious to those skilled in the art that various changes and modifications can be made within the scope of the technical concept of the present invention. If such changes and modifications fall within the scope of the claims, their technical concept should also be regarded as belonging to the present invention.
