Description

Technical Field

[0001] This invention relates to the field of gas-fired clothes dryer technology, and more particularly to a combustion chamber structure and a gas-fired clothes dryer. Background Technology

[0002] Gas-fired clothes dryers utilize the heat generated by burning gas to dry clothes, offering advantages such as convenience, speed, economy, hygiene, environmental friendliness, and leaving clothes fluffy and soft. Currently, the combustion chamber structure of most gas-fired clothes dryers on the market consists of an outer shell with an air inlet and outlet. Inside the shell is a burner. Air enters the outer shell through the inlet, is heated by the burner, and then flows through the outlet into the inner drum to dry the clothes. However, existing gas-fired clothes dryers have a simple combustion chamber structure, low heat utilization, and unsatisfactory drying results. Summary of the Invention

[0003] The purpose of this invention is to provide a combustion chamber structure and a gas-fired clothes dryer that avoids heat loss, ensures effective heat transfer, and has a high heat utilization rate.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A combustion chamber structure, comprising:

[0006] The outer casing has an air inlet and an air outlet;

[0007] Two first reflectors are disposed inside the outer casing and close to the air inlet. Both first reflectors are inclined and the distance between the two first reflectors gradually increases from the air inlet to the air outlet.

[0008] Two second reflectors are disposed inside the outer casing. The two second reflectors are connected one-to-one to the ends of the two first reflectors away from the air inlet, and the second reflectors are vertically arranged.

[0009] The third and fourth reflectors are disposed inside the housing and near the air outlet. The third reflector is inclined above one of the second reflectors, and the fourth reflector is inclined above the other second reflector. The angles between the third and fourth reflectors and their respective corresponding second reflectors are both obtuse angles, and the tilt angle of the fourth reflector is greater than that of the third reflector. The fourth reflector extends above the third reflector.

[0010] The burner is housed within the housing and positioned between the two second reflectors.

[0011] As a preferred technical solution for the combustion chamber structure, a fifth reflector is also included. The fifth reflector is obliquely disposed between the third reflector and the second reflector corresponding to the third reflector, and the angle between the fifth reflector and the corresponding second reflector is greater than the angle between the third reflector and the corresponding second reflector.

[0012] As a preferred technical solution for the combustion chamber structure, the included angle between the first reflector and the corresponding second reflector is 130°-140°, the included angle between the third reflector and the corresponding second reflector is 120°-130°, and the included angle between the fourth reflector and the corresponding second reflector is 140°-150°.

[0013] As a preferred technical solution for the combustion chamber structure, the included angle between the fifth reflector and the corresponding second reflector is 130°-140°.

[0014] As a preferred technical solution for the combustion chamber structure, the outer shell includes a top plate, a first side plate and a third side plate disposed opposite to each other, and a second side plate and a fourth side plate disposed opposite to each other. The first side plate, the second side plate and the third side plate are all connected to the top plate. The fourth side plate is connected to the lower part of the adjacent first side plate and the third side plate. The bottom opening of the outer shell is the air inlet, and the gap between the fourth side plate and the top plate is the air outlet.

[0015] As a preferred technical solution for the combustion chamber structure, the lower end of the fourth reflector is connected to the upper end of the fourth side plate.

[0016] As a preferred technical solution for the combustion chamber structure, both the outer shell and the fourth reflector are made of hot-dip galvanized steel plate DC51D+Z, and both have a thickness of 1mm.

[0017] As a preferred technical solution for the combustion chamber structure, the first and second reflectors are both made of SUS430BA and have a thickness of 1mm, and the third and fifth reflectors are both made of SUS430 and have a thickness of 1mm.

[0018] As a preferred technical solution for the combustion chamber structure, the first reflector, the second reflector, the third reflector, the fourth reflector, and the fifth reflector all have flanges, which are used to connect with the outer shell.

[0019] A gas-fired clothes dryer includes a combustion chamber structure as described in any of the above embodiments.

[0020] The beneficial effects of this invention are:

[0021] This invention provides a combustion chamber structure. First, air enters the outer casing through the air inlet and flows through the gap between two first reflectors to the burner, where it is burned and generates heat. The hot air is reflected by the first reflectors and flows towards the air outlet. Because the first reflectors are tilted, the hot air forms a vortex under the reflection of the first reflectors, preventing heat loss and ensuring effective heat transfer. Second, as the hot air flows towards the air outlet after being reflected by the first reflectors, the second, third, and fourth reflectors isolate the heat from external contact and collect the heat, further preventing heat loss and ensuring effective heat transfer. Finally, when the hot air is transferred along the second reflector to the third and fourth reflectors, because the third and fourth reflectors are tilted, the hot air forms a vortex again under the reflection of the third and fourth reflectors and flows through the gap between the third and fourth reflectors to the air outlet, further preventing heat loss and ensuring effective heat transfer with high heat utilization.

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0029] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0032] like Figures 1 to 4As shown, this embodiment of the invention provides a combustion chamber structure, including a shell 10, a first reflector 20, a second reflector 30, a third reflector 40, a fourth reflector 50, and a burner 70. The shell 10 has an air inlet and an air outlet. Two first reflectors 20 are disposed inside the shell 10, close to the air inlet, and both first reflectors 20 are inclined, with the distance between them gradually increasing from the air inlet to the air outlet. Two second reflectors 30 are disposed inside the shell 10, each connected to one end of the first reflector 20 away from the air inlet, and the second reflectors 30 are vertically arranged. The third reflector 40... The reflector plate 40 and the fourth reflector plate 50 are disposed inside the housing 10 and close to the air outlet. The third reflector plate 40 is obliquely disposed above one of the second reflector plates 30, and the fourth reflector plate 50 is obliquely disposed above the other second reflector plate 30. The angles between the third reflector plate 40 and the fourth reflector plate 50 and their respective second reflector plates 30 are both obtuse angles, and the angle between the fourth reflector plate 50 and its corresponding second reflector plate 30 is greater than the angle between the third reflector plate 40 and its corresponding second reflector plate 30. The fourth reflector plate 50 extends above the third reflector plate 40. The burner 70 is disposed inside the housing 10 and located between the two second reflector plates 30.

[0033] First, air enters the outer casing 10 through the air inlet and flows through the gap between the two first reflectors 20 to the burner 70, where it is burned and generates heat. The hot air, after being reflected by the first reflectors 20, flows towards the air outlet. Because the first reflectors 20 are tilted, the hot air forms a vortex under the reflection of the first reflectors 20, preventing heat loss and ensuring effective heat transfer. Second, as the hot air flows towards the air outlet after being reflected by the first reflectors 20, the second reflector 30, the third reflector 40, and the fourth reflector 5... The first reflector 30 isolates the heat from external contact and gathers the heat, further preventing heat loss and ensuring effective heat transfer. Finally, when the hot air is transferred along the second reflector 30 to the third reflector 40 and the fourth reflector 50, due to the inclined arrangement of the third reflector 40 and the fourth reflector 50, the hot air forms a vortex again under the reflection of the third reflector 40 and the fourth reflector 50, and flows to the air outlet through the gap between the third reflector 40 and the fourth reflector 50, further preventing heat loss and ensuring effective heat transfer.

[0034] In this embodiment, the combustion chamber structure further includes a fifth reflector 60, which is obliquely disposed between the third reflector 40 and the corresponding second reflector 30, with the angle between the fifth reflector 60 and the corresponding second reflector 30 being greater than the angle between the third reflector 40 and the corresponding second reflector 30. By providing the fifth reflector 60, the transition between the second reflector 30 and the third reflector 40 can be made smoother, which is more conducive to the flow of hot air towards the outlet.

[0035] In this embodiment, the angle between the first reflector 20 and the corresponding second reflector 30 is 130°-140°, preferably 139°. The angle between the third reflector 40 and the corresponding second reflector 30 is 120°-130°, preferably 123°. The angle between the fourth reflector 50 and the corresponding second reflector 30 is 140°-150°, preferably 142°. The angle between the fifth reflector 60 and the corresponding second reflector 30 is 130°-140°, preferably 140°. By setting these angles, each reflector can fully exert its function of reflecting and guiding the flow of hot air.

[0036] In this embodiment, the outer casing 10 includes a top plate 11, a first side plate 12, a second side plate 13, a third side plate 14, and a fourth side plate 15. The first side plate 12 and the third side plate 14 are arranged opposite each other, and the second side plate 13 and the fourth side plate 15 are arranged opposite each other. The first side plate 12, the second side plate 13, and the third side plate 14 are all connected to the top plate 11. The fourth side plate 15 is connected to the lower part of the adjacent first side plate 12 and the third side plate 14. The bottom opening of the outer casing 10 is the aforementioned air inlet, and the gap between the fourth side plate 15 and the top plate 11 is the aforementioned air outlet. Preferably, the lower end of the fourth reflector 50 is connected to the upper end of the fourth side plate 15. The outer casing 10 and the fourth reflector 50 are both made of hot-dip galvanized steel sheet DC51D+Z (DC51D+Z is a grade representing pure zinc hot-dip galvanized steel sheet coil), and both are 1mm thick. By selecting the above materials, heat loss can be reduced and reflection efficiency can be improved.

[0037] In this embodiment, the first reflector 20 and the second reflector 30 are both made of SUS430BA and have a thickness of 1 mm. The third reflector 40 and the fifth reflector 60 are both made of SUS430 and have a thickness of 1 mm. By selecting the above materials, heat loss can be reduced and reflection efficiency can be improved.

[0038] In this embodiment, the first reflector 20, the second reflector 30, the third reflector 40, the fourth reflector 50, and the fifth reflector 60 all have flanges 80, which are used to connect with the outer casing 10. This arrangement facilitates the fixing of the first reflector 20, the second reflector 30, the third reflector 40, the fourth reflector 50, and the fifth reflector 60 within the outer casing 10.

[0039] This invention also provides a gas-fired clothes dryer, including the combustion chamber structure described above. By adopting the above combustion chamber structure, heat utilization efficiency can be improved and drying effect can be enhanced.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
