Description

Technical Field

[0001] The present invention relates to the technical field of clothing treatment equipment, and particularly to a combustion chamber structure and a gas dryer. Background Art

[0002] A gas dryer uses gas combustion to generate heat to dry clothes, and has the advantages of convenience, rapidity, economy, hygiene, environmental protection, and the dried clothes being fluffy, soft and compliant. The combustion chamber structure of the current gas dryer includes a housing, the housing has an air inlet and an air outlet, a burner is arranged inside the housing, air enters the housing through the air inlet, and flows through the air outlet to the inner cylinder of the dryer to dry the clothes.

[0003] The temperature provided by the combustion chamber is the main factor determining the drying efficiency. Combustion requires a sufficient temperature to initiate and maintain the reaction. A higher temperature will accelerate the combustion speed and efficiency. To keep the gas burning continuously and form a complete flame, the flame must maintain a relatively high temperature by itself.

[0004] In most current gas dryers, the air entering through the air inlet flows directly towards the burner. The temperature of the incoming air flow is relatively low. When it contacts the flame, the flame temperature will drop, resulting in incomplete combustion, low effective utilization rate of the calorific value, and uneven temperature distribution at each position when entering the cylinder due to insufficient combustion, affecting the drying efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a combustion chamber structure and a gas dryer to solve the technical problem of incomplete combustion existing in the prior art.

[0006] As conceived above, the technical solution adopted by the present invention is as follows:

[0007] A combustion chamber structure, comprising:

[0008] A housing, having an air inlet and an air outlet, and a wind guiding channel is formed between the air inlet and the air outlet inside the housing;

[0009] A combustion chamber body, arranged in the wind guiding channel and close to the air inlet, the combustion chamber body having an air inlet and an air outlet communicated with the wind guiding channel;

[0010] A burner, arranged inside the combustion chamber body;

[0011] An air regulating plate, arranged outside the combustion chamber body and shielding the air inlet, and an air inlet gap communicating with the air inlet is defined between the air regulating plate and the combustion chamber body.

[0012] As a preferred solution of the combustion chamber structure, a baffle extending towards the air inlet is arranged at the edge of the air regulating plate.

[0013] As a preferred embodiment of the combustion chamber structure, the air inlet gap is arranged in a ring around the air inlet, or the air inlet gap is arranged in a strip shape on two opposite sides of the air inlet.

[0014] As a preferred embodiment of the combustion chamber structure, the air regulating plate is detachably connected to the outer shell or the combustion chamber body, and the size of the air inlet gap is adjustable.

[0015] As a preferred embodiment of the combustion chamber structure, an air inlet section is formed inside the combustion chamber body between the burner and the air inlet. Along the direction from the air inlet to the burner, the gas flow area of the air inlet section gradually increases.

[0016] As a preferred embodiment of the combustion chamber structure, an air outlet section is formed inside the combustion chamber body between the burner and the air outlet. Along the direction from the burner to the air outlet, the gas flow area of the air outlet section remains uniform and unchanged.

[0017] As a preferred embodiment of the combustion chamber structure, along the gas flow direction, a bent air guiding path is formed downstream of the air outlet in the air guiding channel, and the air guiding path is bent at least twice.

[0018] As a preferred embodiment of the combustion chamber structure, the air guiding path is in an S shape.

[0019] As a preferred embodiment of the combustion chamber structure, at least three reflecting plates are arranged at intervals along the gas flow direction in the air guiding channel, and the reflecting plates are staggered and distributed on two opposite side walls of the air guiding channel. The reflecting plates guide the gas to flow towards the middle of the air guiding channel and guide the gas to flow towards the air outlet direction.

[0020] A gas dryer includes an inner drum and the combustion chamber structure as described above, and the air outlet is communicated with the inner drum.

[0021] Advantages of the present invention:

[0022] For the combustion chamber structure proposed by the present invention, during use, the outside air enters the air guiding channel of the outer shell from the air inlet and enters the combustion chamber body from the air inlet. Since the air regulating plate blocks the air inlet and defines an air inlet gap communicating with the air inlet between the air regulating plate and the combustion chamber body, the air enters the combustion chamber body from the air inlet gap. The setting of the air regulating plate changes the air inlet direction of the combustion chamber body, plays a buffering role for the air inlet airflow of the combustion chamber body, avoids the impact of the airflow on the burner, ensures that the burner burns at a relatively high stable temperature, and ensures sufficient combustion. Moreover, the air regulating plate can prevent heat loss in the combustion chamber body. Description of the drawings

[0039] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] See Figures 1 to 7 , an embodiment of the present invention provides a combustion chamber structure, including a housing 10, a combustion chamber body 20, a burner 30, and an air regulating plate 40. The housing 10 has an air inlet 101 and an air outlet 102, and a wind guiding channel is formed between the air inlet 101 and the air outlet 102 inside the housing 10; the combustion chamber body 20 is arranged in the wind guiding channel and close to the air inlet 101. The combustion chamber body 20 has an air inlet 201 and an air outlet 202 communicating with the wind guiding channel. The burner 30 is arranged inside the combustion chamber body 20, and the air regulating plate 40 is arranged outside the combustion chamber body 20 and blocks the air inlet 201. An air inlet gap 401 communicating with the air inlet 201 is defined between the air regulating plate 40 and the combustion chamber body 20.

[0041] During use, the outside air enters the wind guiding channel of the housing 10 from the air inlet 101, and the air enters the combustion chamber body 20 from the air inlet 201. Since the air regulating plate 40 blocks the air inlet 201 and an air inlet gap 401 communicating with the air inlet 201 is defined between the air regulating plate 40 and the combustion chamber body 20, the air enters the combustion chamber body 20 from the air inlet gap 401. The setting of the air regulating plate 40 changes the air inlet direction of the combustion chamber body 20, plays a buffering role in the air inlet airflow of the combustion chamber body 20, avoids the direct impact of the airflow on the burner 30, ensures that the burner 30 burns at a relatively high stable temperature, and ensures sufficient combustion. Moreover, the air regulating plate 40 can prevent the heat loss inside the combustion chamber body 20.

[0042] Under normal circumstances, the air inlet 101 is arranged at the bottom of the housing 10, and the air outlet 102 is arranged at the side of the housing 10, making full use of the principle that hot air rises to guide the hot air upward. The air regulating plate 40 is arranged between the air inlet 101 of the housing 10 and the air inlet 201 of the combustion chamber body 20, and plays a guiding role for the air entering the combustion chamber body 20.

[0043] The air inlet gap 401 is arranged in a ring around the air inlet 201, or the air inlet gap 401 is arranged in a strip shape on the opposite sides of the air inlet 201. In this embodiment, the air inlet 201 is rectangular, so the air inlet gap 401 is arranged in a strip shape on the opposite sides of the air inlet 201, which is convenient for installing the air regulating plate 40. Specifically, both ends of the air regulating plate 40 are connected to the housing 10, and long strip-shaped air inlet gaps 401 are formed between the two sides of the air regulating plate 40 and the air inlet 201.

[0044] In other embodiments, the air inlet gap 401 can be arranged in a ring in the circumferential direction of the air inlet 201. The air inlet 201 can be circular, square or oval, and the shape of the air regulating plate 40 can be set according to the shape of the air inlet 201.

[0045] A baffle 41 extending towards the air inlet 201 is arranged at the edge of the air regulating plate 40. The arrangement of the baffle 41, on the one hand, avoids the sharp edge of the air regulating plate 40, and on the other hand, plays a role in blocking the intake air flow of the air inlet 201.

[0046] In some embodiments, the baffle 41 can be detachably connected to the air regulating plate 40. By replacing the baffle 41 with different sizes, the size of the air inlet gap 401 can be changed, and the size of the air inlet gap 401 can be adjusted without disassembling the air regulating plate 40.

[0047] In this embodiment, the air regulating plate 40 is detachably connected to the housing 10 or the combustion chamber body 20, and the size of the air inlet gap 401 is adjustable. The closer the air regulating plate 40 is to the air inlet 201, the smaller the air inlet gap 401.

[0048] It can be understood that the burner 30 is communicated with the gas source through a gas channel, and a gas valve is connected to the gas channel to open or close the gas channel. The working principle of the burner 30 will not be elaborated here, and the existing burner 30 is adopted. The combustion chamber body 20 where the burner 30 is located needs to enter air to ensure normal vortex circulation in the combustion chamber body 20. In this embodiment, two burners 30 can be arranged.

[0049] Due to the setting of the air regulating plate 40, turbulent flow is formed after the cold air enters the combustion chamber body 20. In the turbulent state, heat will flow in a vortex and swirl manner in the combustion chamber body 20, making the effective heat transfer area of the flow region relatively increased. When in the laminar state of heat, the heat flow is relatively orderly and the heat transfer area is relatively small. Therefore, the effective heat transfer area of turbulent heat transfer is larger, and the heat transfer interface can be utilized more fully. So the heat release coefficient in turbulent flow is higher than that in laminar flow, and the heat transfer effect of turbulent flow is better.

[0050] An intake section is formed inside the combustion chamber body 20 between the burner 30 and the air inlet 201. Along the direction from the air inlet 201 to the burner 30, the gas flow area of the intake section gradually increases. The change in the cross-sectional area of the intake section causes the gas to be reflected and flow towards the burner 30, forming a vortex, and the gas can be in full contact with the burner 30. The change in the cross-sectional area of the intake section cooperates with the guiding of the intake air flow by the air regulating plate 40, further enhancing the turbulent flow phenomenon, making the vortex and swirl flow located around the burner 30, facilitating the full contact between the air and the burner 30, improving the heat transfer efficiency, and ensuring complete combustion.

[0051] In this embodiment, an exhaust section is formed inside the combustion chamber body 20 between the burner 30 and the air outlet 202. Along the direction from the burner 30 to the air outlet 202, the gas flow area of the exhaust section remains uniformly unchanged. After the air is heated by the burner 30, the hot air smoothly flows from the exhaust section to the air guiding channel. In other embodiments, along the direction from the burner 30 to the air outlet 202, the gas flow area of the exhaust section gradually increases. After the air is heated by the burner 30, the change in the cross-sectional area of the exhaust section causes the gas to be reflected and flow into the air guiding channel, and the hot air smoothly flows from the exhaust section to the air guiding channel.

[0052] Specifically, the combustion chamber body 20 is surrounded by several baffles, and at least the bottom of one baffle extends inwardly and obliquely to form an intake section with a gradually increasing gas flow area along the direction from the air inlet 201 to the burner 30. In this embodiment, the combustion chamber body 20 is surrounded by four baffles, including two relatively arranged first baffles 21, and the bottoms of the two first baffles 21 both extend inwardly and obliquely so that the bottoms of the two first baffles 21 are close to each other. The bending angle of the first baffle 21 can be 130° - 140°.

[0053] The combustion chamber body 20 further includes two relatively arranged second baffles 22, and the two second baffles 22 are arranged in parallel. Of course, in some embodiments, the bottoms of the two second baffles 22 can also extend inwardly and obliquely.

[0054] The combustion chamber body 20 is located in the air guiding channel and close to the air inlet 101. Downstream of the combustion chamber body 20, the air guiding channel also has a certain length to facilitate the diversion of the hot air formed after passing through the combustion chamber body 20.

[0055] In some embodiments, a seal is provided between the outer wall of the combustion chamber body 20 and the inner wall of the air guiding channel, such that all the air entering through the air inlet 101 enters the combustion chamber body 20 through the air inlet 201. In this embodiment, in order to ensure a sufficient air flow rate, a gap is provided between the outer wall of the combustion chamber body 20 and the inner wall of the air guiding channel, allowing a small portion of the air to flow through the outer surface of the combustion chamber body 20 and exchange heat with the outer surface of the combustion chamber body 20, and further exchange heat with the hot air flowing out of the combustion chamber body 20 downstream of the combustion chamber body 20. However, the vast majority of the air still flows into the combustion chamber body 20 through the air inlet 201, passes through the burner 30, and flows out through the air outlet 202 into the air guiding channel.

[0056] Along the gas flow direction, a bent air guiding path is formed in the air guiding channel downstream of the air outlet 202, and the air guiding path is bent at least twice. This causes the hot air to form a turbulent flow phenomenon in the air guiding channel. In the turbulent state, heat will flow in vortices and eddies in the air guiding channel, increasing the effective heat transfer area of the flow region.

[0057] The outside air enters the air guiding channel of the housing 10 through the air inlet 101. Part of the air flows over the outer surface of the combustion chamber body 20 and exchanges heat with the combustion chamber body 20 to form hot air. Part of the air enters the combustion chamber body 20 through the air inlet 201, fully contacts the burner 30 to form hot air and flows out through the air outlet 202. Downstream of the air outlet 202, the hot air in the air guiding channel converges and flows along the bent air guiding path, forming vortices and eddies, and fully making contact and heat transfer, so that the outlet air temperature at the air outlet 102 is uniform. Since the air guiding path is bent at least twice, there are at least two vortex regions, enabling the gas to exchange heat fully and the temperature to be more uniform.

[0058] At least three reflecting plates are provided at intervals along the gas flow direction in the air guiding channel, and the reflecting plates are staggered and distributed on the two opposite side walls of the air guiding channel. The reflecting plates guide the gas to flow towards the middle of the air guiding channel and towards the air outlet 102. Since the reflecting plates play a role in reflecting and guiding the hot air, the hot air is guided to flow towards the middle of the air guiding channel, concentrating the heat, so that almost all the hot air flows into the air guiding channel through the air outlet 202, improving the calorific value utilization rate.

[0059] In this embodiment, the air guiding path is in an S shape, extending the gas flow path to enable the gas to make full contact. In other embodiments, the air guiding path can be in a W shape, a wave shape, a Z shape or other shapes.

[0060] Specifically, three reflecting plates are arranged at intervals along the gas flow direction in the air guiding channel, which are the first reflecting plate 51, the second reflecting plate 52 and the third reflecting plate 53 in sequence. The first reflecting plate 51 and the third reflecting plate 53 are connected to one inner wall of the air guiding channel and are inclined towards the air outlet 102. The second reflecting plate 52 is connected to the other inner wall of the air guiding channel and is inserted between the first reflecting plate 51 and the third reflecting plate 53. A bent air guiding path is formed by the first reflecting plate 51, the second reflecting plate 52 and the third reflecting plate 53, and the air guiding path is bent at least twice.

[0061] A first passage 54 allowing air flow to pass through is formed between the end of the first reflecting plate 51 and the plate body of the second reflecting plate 52, and a second passage 55 allowing air flow to pass through is formed between the end of the second reflecting plate 52 and the plate body of the third reflecting plate 53. During the air flow, the air passes through the first passage 54 and the second passage 55 in sequence, realizing the flow along the bent path.

[0062] Specifically, the hot air coming out of the air outlet 202 of the combustion chamber body 20 flows along the first reflecting plate 51 to the second reflecting plate 52 and is reflected by the second reflecting plate 52 to form a vortex. The hot air passing through the first passage 54 flows along the second reflecting plate 52 to the third reflecting plate 53 and is reflected by the third reflecting plate 53 to form a vortex. Therefore, a vortex area is formed in the area surrounded by the combustion chamber body 20, the first reflecting plate 51 and the second reflecting plate 52, and another vortex area is formed in the area surrounded by the first reflecting plate 51, the second reflecting plate 52 and the third reflecting plate 53. The two vortex areas enable the gas to be fully mixed and the temperature to be more uniform.

[0063] In this embodiment, the first reflecting plate 51 is a flat plate. The first reflecting plate 51 is located above the air outlet 202. One end of the first reflecting plate 51 is connected to one inner wall of the air guiding channel, and the other end of the first reflecting plate 51 extends obliquely in a direction away from the air outlet 202.

[0064] The second reflecting plate 52 is a bent plate. The second reflecting plate 52 includes a first inclined portion 521 and a first parallel portion 522. One end of the first inclined portion 521 is connected to the other inner wall of the air guiding channel, and the other end of the first inclined portion 521 extends obliquely in a direction away from the air outlet 202. The first parallel portion 522 is arranged at the end of the first inclined portion 521 away from the air outlet 202 and extends parallel to the air outlet direction of the air outlet 102. That is to say, the first inclined portion 521 is inclined with respect to the air outlet direction of the air outlet 202, and the first parallel portion 522 is parallel to the air outlet direction of the air outlet 102. The setting of the first parallel portion 522 makes the second reflecting plate 52 closer to the third reflecting plate 53, extends the air flow path, and the second passage 55 between the second reflecting plate 52 and the third reflecting plate 53 is smaller, which plays an accelerating role on the gas.

[0065] The third reflector 53 is a bent plate. The third reflector 53 includes a second inclined portion 531 and a second parallel portion 532. One end of the second inclined portion 531 is connected to one inner wall side of the air guiding channel. The other end of the second inclined portion 531 inclines away from the air outlet 202. The second parallel portion 532 is arranged at the end of the second inclined portion 531 away from the air outlet 202 and is parallel to the air outlet direction of the air outlet 102. That is to say, the second inclined portion 531 inclines relative to the air outlet direction of the air outlet 202, and the second parallel portion 532 is parallel to the air outlet direction of the air outlet 102. By setting the third reflector 53 as a bent plate, its bending position guides and accelerates the air flow, enabling the air flow to quickly flow to the air outlet 102.

[0066] In this embodiment, the combustion chamber body 20 and the air regulating plate 40 can be made of stainless steel or carbon steel with a thickness of 1 mm. The first reflector 51, the second reflector 52, and the third reflector 53 are made of copper or copper-aluminum alloy with a relatively high equivalent thermal conductivity and a thickness of 1 mm.

[0067] In this embodiment, the housing 10 includes a front plate, a rear plate, and side plates. The front plate and the rear plate are arranged at intervals, and the side plates are arranged between the front plate and the rear plate. The side plates can be made of stainless steel or carbon steel with a low equivalent thermal conductivity and a thickness of 1 mm to better preserve the temperature. The front plate can be made of hot-dip galvanized sheet with a thickness of 1 mm.

[0068] The embodiment of the present invention further provides a gas dryer, which includes an inner drum and the above-mentioned combustion chamber structure, and the air outlet 102 is communicated with the inner drum. During drying, the fan in the gas dryer is turned on to form a negative pressure in the air guiding channel. The external air flow enters the air guiding channel from the air inlet 101, passes through the air inlet gap 401 and enters the combustion chamber body 20. Due to the setting of the air regulating plate 40, the air inlet direction of the combustion chamber body 20 is changed. Coupled with the fact that the gas flow area gradually increases along the air inlet 201 to the burner 30 direction in the intake section, the gas forms a vortex in the combustion chamber body 20, enabling the gas to fully contact the burner 30. After being heated by the burner 30, the hot air flows to the air guiding channel from the air outlet 202. After passing through the bent air guiding path in the air guiding channel, the hot air is fully mixed and uniform, and flows into the inner drum from the air outlet 102 at a stable temperature.
