Description

Technical Field

[0001] The invention relates to a dust cleaning structure, and more particularly to a dust cleaning structure for a heat dissipation pipe and a real fire fireplace. Background Art

[0002] A real fire fireplace is a heating device that uses fuel pellets or wood to generate heat energy.

[0003] The existing real fire fireplace heats the fresh air flow by heat exchange. For example, a Chinese patent document with the publication number CN221146592U was retrieved, and its patent name is a heat exchange air duct device for a fireplace. Figure 2-5 The exhaust gas burned in the furnace body flows in from the air intake radiator 3, turns in the top hot air chamber 2, and flows out through the exhaust radiator 4. The fresh air contacts the air intake radiator 3 and the exhaust radiator 4 to achieve heat exchange.

[0004] During the long-term combustion of the fireplace, a large amount of impurities such as wood ash and resin mixed in the exhaust gas generated by the fireplace will adhere to the air intake heat dissipation pipe 3 and the exhaust heat dissipation pipe 4, which will weaken the heat transfer performance of the air intake heat dissipation pipe 3 and the exhaust heat dissipation pipe 4 to the outside, thereby reducing the heat exchange efficiency of the fresh air.

[0005] Since the tops of the air intake radiating pipe 3 and the exhaust radiating pipe 4 are sealed hot air chambers 2, it is very difficult to clean the air intake radiating pipe 3 and the exhaust radiating pipe 4. Summary of the invention

[0006] The object of the present invention is to provide a dust cleaning structure for a heat dissipation pipe, which adopts a dust cleaning component suspended in the heat dissipation pipe and can realize a convenient dust cleaning action on the heat dissipation pipe by shaking the dust cleaning component.

[0011] Preferably, there are multiple suspension rods, and the multiple suspension rods are fixedly connected.

[0012] Preferably, multiple suspension rods are arranged in parallel, connecting rods are fixed at the ends of the multiple suspension rods, a guide rod is fixed in the conversion cabin, the connecting rod is provided with a guide hole, the guide rod passes through the guide hole, and the guide hole is a waist-shaped hole; the short-diameter hole position of the waist-shaped hole and the guide rod blocking constraint limit the relative left and right swing of the connecting rod; the long-diameter hole position of the waist-shaped hole gives the guide rod relative forward and backward swinging space, which is convenient for the push rod to move forward and backward when swinging.

[0013] Preferably, the conversion cabin includes a cover body, and a protrusion facing the suspension rod is fixed on the inner top of the cover body. There are at least two protrusions, and the protrusions are arranged at the same height and located on both sides of the suspension rod.

[0018] In summary, the present invention has at least one of the following beneficial effects:

[0019] (1) The horizontal pulling of the cross bar drives the vertical movement of the push rod, thereby driving the cleaning part to vibrate back and forth in the heat dissipation pipe. During the shaking process, the arc-shaped rod of the cleaning part contacts the inner wall of the heat dissipation pipe by impact and friction, thereby cleaning the inner wall of the heat dissipation pipe. This design allows users to complete the cleaning action without opening the hot air chamber, making cleaning more convenient.

[0021] (3) The spiral metal part can be a spring. Its spiral structure also has the function of guiding the airflow, so that the exhaust gas flows along a spiral trajectory. Compared with the straight flow along the heat dissipation pipe, the spiral trajectory increases the airflow path, and the heat exchange performance of the exhaust gas flow in the heat dissipation pipe is improved.

[0044] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0045] The hot gas and waste gas flow in the present invention both refer to the hot gas flow including flue gas generated by combustion in the furnace.

[0046] Example 1, a dust cleaning structure for a heat dissipation pipe, referring to Figure 1 , including a heat dissipation pipe 01 for hot air flow, the heat dissipation pipe 01 has four rows, namely two rows of intake pipes 011 and two rows of exhaust pipes 012;

[0047] A plurality of heat sinks are fixed on the outer wall of the heat dissipation pipe 01, and the fresh air flows through the heat sinks to heat the fresh air;

[0048] Reference Figure 2 A sealed conversion cabin 02 is fixed on the top of the heat dissipation pipe 01. The conversion cabin 02 includes a bottom plate and a cover 021. The bottom plate is fixed on the upper end of the heat dissipation pipe 01. The cover 021 seals the bottom plate. The cover 021 and the bottom plate can be locked by screws, buckles, or directly welded;

[0049] Since the cover body 021 covers the bottom plate, the waste heat from the upper end of the heat dissipation pipe 01 flows in the conversion cabin 02. The specific flow path is that the waste gas from the intake pipe 011 enters the conversion cabin 02 from its upper end, and the waste gas in the conversion cabin 02 enters the exhaust pipe 012 and flows downward therefrom.

[0050] Four rows of suspension rods 041 are placed in the conversion cabin 02. The suspension rods 041 are arranged in parallel. The ends of the four suspension rods 041 are fixed by connecting rods 044, so that the four suspension rods 041 can move up and down synchronously.

[0051] The two middle hanging rods 041 are welded with two clamping plates 047, and the push rod 042 is inserted from the lower clamping plate 047, and the upper end of the push rod 042 is held against the upper clamping plate 047 in a resisting manner. A bayonet 048 is inserted into the push rod 042, and the bayonet 048 can be an R-shaped pin. The bayonet 048 is located between the two clamping plates 047, and the function of the bayonet 048 is to prevent the push rod 042 from slipping off the lower clamping plate 047;

[0052] When the push rod 042 rises, it pushes the upper clamping plate 047 to lift up the four hanging rods 041;

[0053] When the push rod 042 descends, the latch 048 can pull the clamping plate 047 below to drive the entire suspension rod 041 to descend. During the descent, the gravity of the suspension rod 041 itself assists the descent.

[0054] A plurality of cleaning parts 03 are suspended on the hanging rod 041. The cleaning parts 03 are metal springs. The upper ends of the cleaning parts 03 have hanging hooks. The arc rods 031 are continuously connected to form a spiral spring structure.

[0055] Reference Figure 2 and Figure 3 Each metal spring is inserted into the heat dissipation tube 01 below, and the metal springs and the heat dissipation tube 01 correspond to each other one by one; there is a gap between the cleaning part 03, that is, the outer edge of the metal spring and the inner wall of the heat dissipation tube 01. In the cross-sectional direction, the gap distance can be in the range of 0.1-3mm, and in this embodiment, the gap distance is 1mm.

[0056] The gap is set, so that the cleaning part 03 can move up and down smoothly in the heat pipe 01, and the cleaning method of the cleaning part 03 relies on the contact actions such as friction and impact on the inner wall of the heat pipe 01 when the cleaning part 03 shakes up and down, so as to clean the inner wall of the heat pipe 01. Of course, the shaking action can also shake off the dust attached to the cleaning part 03 itself, and the shaken-off dust will fall.

[0057] In order to facilitate the operation of the dust cleaning part 03, the following structure is adopted:

[0058] Reference Figure 1 , Figure 4 and Figure 5 A connecting pipe 06 inserted into the fireplace is fixed at the bottom of the conversion cabin 02, and the connecting pipe 06 connects the furnace and the conversion cabin 02, and the connecting pipe 06 passes through the heat sink; the push rod 042 is located in the connecting pipe 06, and the two ends of the push rod 042 are respectively inserted into the furnace and the conversion cabin 02 through the connecting pipe 06;

[0059] There is a gap between the push rod 042 and the connecting pipe 06, which facilitates the movement of the push rod 042 in the connecting pipe 06; the connecting pipe 06 provides the push rod 042 with a relatively isolated lifting space, and the connecting pipe 06 avoids the contact between the waste heat and the fresh air at the position of the push rod 042; in other embodiments, a heat-resistant elastic sealing ring can also be arranged between the bottom of the conversion cabin 02 and the push rod 042 to improve the sealing performance of the sliding point between the push rod 042 and the conversion cabin 02.

[0060] The push rod 042 moves vertically, and the cross bar 043 moves horizontally. A steering assembly 05 is provided between the cross bar 043 and the push rod 042. That is to say, by pulling the cross bar 043 back and forth horizontally, the push rod 042 can be driven to move back and forth vertically.

[0061] The steering assembly 05 includes a mounting seat 051, and the mounting seat 051 is fixed in the furnace body 081;

[0062] The mounting seat 051 is connected to a rotating wheel 052 via a shaft rod. Two rotating shafts 053 are fixed on the side of the rotating wheel 052. The push rod 042 and the cross bar 043 are eccentrically connected relative to the rotating wheel 052. The rotating wheel 052 is an eccentric wheel.

[0063] The push rod 042 is hinged to a rotating shaft 053 through a shaft sleeve, and one end of the cross bar 043 is hinged to another rotating shaft 053 through a shaft sleeve. When the user pushes or pulls the cross bar 043, the rotating wheel 052 is driven to rotate, and the rotation drives the push rod 042 to move up and down.

[0064] Working principle: the user pushes and pulls the cross bar 043, and the cross bar 043 drives the push rod 042 to move up and down through the steering assembly 05, thereby driving the spring to move up and down. The spring is in a suspended state, so when the spring shakes up and down, it can collide with the inner wall of the heat pipe 01, and the inner wall of the heat pipe 01 is cleaned, and the shaking method can also partially clean the dust on the spring. The present invention does not need to disassemble the conversion cabin 02, and does not require the user to reach into the furnace body 081, so the heat pipe 01 can be easily cleaned, and the push rod 042 can move up and down to complete the cleaning of all the heat pipes 01. Compared with the traditional cleaning of a single heat pipe 01, the present invention has a high cleaning efficiency; the convenient cleaning structure can enhance the user's enthusiasm for cleaning, so that the inner wall of the heat pipe 01 is not easy to accumulate dust, and the heat exchange efficiency between the heat pipe 01 and the external fresh air is improved.

[0065] Embodiment 2, a dust cleaning structure of a heat dissipation pipe, which is different from Embodiment 1 in that, referring to Figure 6 , steering assembly 05, its mounting seat 051 is rotatably connected with a vertically arranged cam 054, a roller 055 is installed at the lower end of the push rod 042, the roller 055 abuts against the edge of the cam 054, a rotating shaft 053 is fixed to the side of the cam 054, and one end of the cross bar 043 is hinged to the rotating shaft 053.

[0066] By pulling the cross bar 043, the cam 054 rotates, and the cam 054 can push the push rod 042 to move up and down.

[0067] Embodiment 3, a dust cleaning structure of a heat dissipation pipe, which is different from Embodiment 1 or Embodiment 2 in that, referring to Figure 7 The arc rod 031 is a semicircular rod, and a plurality of arc rods 031 form a group. The arc rods 031 in the same group are located on the same side, and the upper and lower adjacent arc rods 031 are fixedly connected by welded short rods;

[0068] There are eight continuous arc-shaped rods 031 on one side, and six continuous arc-shaped rods 031 on the other side.

[0069] The dust cleaning member 03 is arranged hollow, and includes a plurality of arc-shaped rods 031 connected in sequence.

[0070] Embodiment 4, a dust cleaning structure of a heat dissipation pipe, which is different from Embodiment 1 or Embodiment 2 or Embodiment 3 in that, referring to Figure 2 and 8 The conversion cabin 02 includes a cover body 021, and a protrusion 022 facing the suspension rod 041 is fixed to the inner top of the cover body 021. The protrusion 022 is a U-shaped metal block, and the protrusion 022 is welded to the inner top of the cover body 021;

[0071] There are two protrusions 022 . The two protrusions 022 have the same height, which is an equal height setting. The protrusions 022 are located on both sides of the suspension rod 041 .

[0072] During the rising process of the suspension rod 041, since the suspension rod 041 is long and the springs are not evenly distributed on the suspension rod 041, the suspension rod 041 will tilt toward one end along its length direction during the rising process; if the suspension rod 041 tilts too much, the spring hanging at one end will rise too high, and the spring hanging at the other end will not rise enough. The shaking amplitude of the spring that does not rise enough will be reduced, so that its dust cleaning ability will be weakened;

[0073] In order to ensure that the suspension rod 041 is in a balanced state when it rises to the top, the bump 022 design is adopted.

[0074] The hanging rod 041 tilts like a seesaw when rising, with one end too high and the other end too low, so the protrusion 022 will first contact the connecting rod 044 at the high end to achieve the purpose of blocking and limiting. The connecting rod 044 fixes one end of the four hanging rods 041;

[0075] As the push rod 042 rises further, the end that is too high is restricted from moving upward, and the end that is too low will rotate around the push rod 042 to correct the position until the two ends of the suspension rod 041 are as balanced as possible. At this time, the connecting rods 044 at both ends abut against the two protrusions 022. This design relies on the abutting connection between the push rod 042 and the suspension rod 041, which gives the suspension rod 041 the freedom to swing.

[0076] Another purpose of the protrusion 022 is to control the rising height of the hanging rod 041. The height of the conversion cabin 02 is higher than the rising height of the hanging rod 041, and the height range of the conversion cabin 02 is 3-6 cm. In other embodiments, the internal height size of the conversion cabin 02 is preferably as follows: the height of the conversion cabin 02 is four centimeters, the height of the connecting rod 044 is one centimeter, the height of the protrusion 022 is one centimeter, the connecting rod 044 and the hanging rod 041 are fixed, so when the connecting rod 044 hits the two protrusions 022, the hanging rod 041 rises by two centimeters. The four-centimeter height is set to increase the space of the conversion cabin 02, so that the conversion cabin 02 has enough space for the waste heat gas flow conversion; and after the space of the conversion cabin 02 is increased, the dust accumulation capacity of the inner wall of the conversion cabin 02 is improved. Since the inner wall area of ​​the conversion cabin 02 is increased by the space of the conversion cabin 02, the dust accumulation on the inner wall of the conversion cabin 02 of the present invention is thinner during the same burning time period of the fireplace, and the dust accumulation in the conversion cabin 02 is reduced as much as possible. If the conversion cabin 02 is not cleaned for a long time, it will not affect the performance of the fireplace too much.

[0077] Embodiment 5, a dust cleaning structure of a heat dissipation pipe, which is different from any one of Embodiments 1 to 4 in that, referring to Figure 2 , Figure 3 and Fig. 9 A guide rod 045 is fixed to the bottom plate of the conversion cabin 02, a connecting block is fixed to the connecting rod 044, a guide hole 046 is opened in the connecting block, and the guide rod 045 passes through the guide hole 046.

[0078] The guide hole 046 is a waist-shaped hole, which is a long hole, so its shortest hole diameter is defined as the short diameter, and its longest hole diameter is defined as the long diameter; Figure 3 The dotted line direction is the short diameter direction.

[0079] In the present invention, the short diameter direction and the long diameter direction of the oblong hole will be perpendicular to each other;

[0080] The short diameter of the waist-shaped hole extends in the same direction as the length of the hanging rod 041, and the guide rod 045 and the short diameter hole of the waist-shaped hole are limited and matched, and the short diameter hole and the guide rod 045 limit the left and right relative swinging. Since the guide rod 045 is fixed to the fireplace, the connecting rod 044 is limited to swing left and right.

[0081] Such a design is to further limit the inclination of the suspension rod 041 along its length direction during the rising process, so that the suspension rod 041 can rise more smoothly.

[0082] When the push rod 042 is driven by the eccentric wheel, it will swing slightly when it moves up and down. Fig. 9 As shown, the suspension rod 041 will also tend to swing back and forth under the push of the push rod 042, and the direction of the suspension rod 041's swinging back and forth is exactly the direction of the long diameter of the waist-round hole. The long diameter direction of the waist-round hole provides swinging space for the guide rod 045, thereby avoiding the waist-round hole and the guide rod 045 from getting stuck when they move back and forth relative to each other.

[0083] Embodiment 6, a combustion wall, comprising a ash cleaning structure of a heat dissipation pipe of any one of Embodiments 1 to 5, referring to Figure 10-12 , including a furnace body 081, the furnace body 081 is provided with a furnace 082, the furnace 082 is used to burn pellets or wood; the heat dissipation pipe 01 and the conversion cabin 02 are located above the furnace 082; the steering assembly 05 is installed on the transverse exhaust duct 07 inside the furnace 082 by screws, and the airflow of the exhaust pipe 012 will flow to the transverse exhaust duct 07, and the exhaust heat is discharged by connecting the two ends of the transverse exhaust duct 07 with the external chimney;

[0084] The cross bar 043 is located in the furnace chamber 082 and extends from the front end of the furnace body 081 , and a button is installed on the extending portion of the cross bar 043 .

[0085] The cleaning part 03 is a spring, which also has the following effects: the spring is elastic, and when the spring moves to the bottom, the spring can shake slightly elastically, and its own elastic shaking also has a cleaning effect; the spiral structure of the spring has sufficient spiral gaps, so that the cleaned ash body falls along the spiral gaps, and the ash body is quickly discharged after cleaning.

[0086] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
