Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a combustion chamber structure and clothing processing equipment. Background Technology

[0002] Gas dryers use 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 gas dryers on the market includes an outer shell with an air inlet and an air outlet. Inside the outer shell is a burner. Air enters the outer shell through the air inlet, is heated by the burner, and then flows through the air outlet into the inner drum of the gas dryer to dry the clothes.

[0003] In order to allow more heat to enter the inner drum of the dryer, existing technologies have installed multiple reflectors in the outer shell to reflect and guide the hot airflow in the outer shell multiple times, thereby preventing heat loss, ensuring effective heat transfer, and improving heat utilization.

[0004] However, in the aforementioned scheme of setting multiple reflectors in the outer casing, the reflectors occupy space within the casing, reducing the internal cavity volume and thus decreasing the capacity to accommodate hot airflow, which is detrimental to the flow of hot air. Furthermore, hot airflow is prone to generating eddies at the bends of the reflectors, increasing resistance and hindering smooth flow. This obstructed flow of hot air reduces the velocity of the airflow entering the inner drum of the gas dryer, affecting both airflow circulation efficiency and drying efficiency.

[0005] Therefore, there is an urgent need for a combustion chamber structure and clothing processing equipment to solve the above problems. Summary of the Invention

[0046] Figure 1 This diagram illustrates a partial structure of the garment processing device provided in an embodiment of the present invention. Figure 1; Figure 2 This figure shows a partial structural front view of the clothing processing equipment provided in an embodiment of the present invention; Figure 3 This diagram illustrates a partial structure of the garment processing device provided in an embodiment of the present invention. Figure 2 ; Figure 4 A partial structural side view of the garment processing device provided in an embodiment of the present invention is shown. (Refer to...) Figures 1-4 This embodiment provides a combustion chamber structure and a clothing processing device. The clothing processing device includes an inner drum 10 and the combustion chamber structure provided in this embodiment. The inner drum 10 is rotatable around its own axis and can accommodate clothing. The combustion chamber structure is located at the rear end of the inner drum 10 along its axial direction and can guide hot airflow into the inner drum 10 for drying clothing. In this embodiment, the clothing processing device can specifically be a gas-fired dryer.

[0047] Reference Figures 1-3 The garment processing equipment also includes an air inlet structure 20, a fan chamber 30, and an air inlet fan 40. The air inlet structure 20 is located below the inner drum 10 and extends along the axial direction of the inner drum 10 to its rear end. The air inlet of the air inlet structure 20 faces the same direction as and is approximately flush with the opening of the inner drum 10. The fan chamber 30 is connected to the outlet of the air inlet structure 20, and the air inlet fan 40 is connected to the fan chamber 30. The air inlet fan 40 draws air through the fan chamber 30 and the air inlet structure 20 to create a negative pressure state in the inner drum 10. At this time, the hot airflow in the combustion chamber structure can enter the inner drum 10 from the rear end along the axial direction to contact the clothes in the inner drum 10. During the rotation of the inner drum 10, the hot airflow fully contacts the clothes to achieve drying.

[0048] Figure 5 This diagram shows a partial structural schematic of the combustion chamber structure provided in an embodiment of the present invention; Figure 6 This diagram shows a partial front view of the combustion chamber structure provided in an embodiment of the present invention. (Refer to...) Figure 3 , Figure 5 and Figure 6The combustion chamber structure includes an outer shell 100, a burner 300, a heat reflector assembly, and an airflow drive device 200. The outer shell 100 includes a front back panel, a rear back panel 140, a top plate, and two side panels. The front back panel and rear back panel 140 are arranged parallel to each other and spaced apart. The two side panels are also arranged parallel to each other and spaced apart, each sandwiched between the front back panel and rear back panel 140. The top plate is located on top of the front back panel, rear back panel 140, and two side panels. The outer shell 100 has an airflow inlet 110 and an airflow outlet 120. The airflow inlet 110 is located at the lower end of the outer shell 100 directly opposite the fan chamber 30. The airflow outlet 120 is opened on the rear back panel 140 and connects to the hot air inlet at the rear end of the inner drum 10 of the garment processing equipment along its axis. Both the burner 300 and the heat reflector assembly are located inside the housing 100. The burner 300 can heat the airflow, and the heat reflector assembly can reflect and guide the hot airflow to the airflow outlet 120.

[0049] The aforementioned heat reflector assembly reflects and guides the hot airflow within the outer casing 100, preventing heat loss and ensuring effective heat transfer. The airflow drive device 200, located at the airflow outlet 120, draws the hot airflow from the outer casing 100 to the inner cylinder 10. By installing the airflow drive device 200, the direction of the hot airflow within the outer casing 100 can be forcibly altered, increasing the velocity of the hot air entering the inner cylinder 10, improving hot air circulation efficiency, and thus enhancing drying efficiency.

[0050] Specifically, refer to Figure 3 , Figure 5 and Figure 6 The outer casing 100 is also provided with a support 160, and the burner 300 is supported and installed in the outer casing 100 by the support 160. Airflow enters the outer casing 100 through the airflow inlet 110, and after being heated by the burner 300, it flows through the airflow outlet 120 to the inner drum 10 to dry the clothes.

[0051] More specifically, the heat reflector assembly includes a first reflector 151, a second reflector 152, a third reflector 153, a fourth reflector 154, and a fifth reflector 155. The first reflectors 151 are two inclined and symmetrically arranged, forming an airflow inlet 110 between them. Along the direction of airflow, the two first reflectors 151 are far apart from each other.

[0052] There are two second reflectors 152, which are arranged parallel to each other and parallel to the rear back panel 140. One second reflector 152 is spaced apart from the rear back panel 140, and the other second reflector 152 is spaced apart from the front back panel. The two second reflectors 152 correspond one-to-one and are angledly connected above the two first reflectors 151. The burner 300 is positioned between the two second reflectors 152. The two first reflectors 151 generate beneficial vortices by reflecting the airflow, preventing heat loss. The two second reflectors 152 guide the airflow upward and isolate heat from direct contact with the outer casing 100, reducing heat loss.

[0053] More specifically, there is one third reflector 153, which is disposed above and connected to the second reflector 152 near the front back panel, and extends gradually away from the front back panel. There is one fourth reflector 154, which is disposed above and connected to the third reflector 153, and extends gradually away from the front back panel, with a length greater than that of the third reflector 153, thus blocking the area above the third reflector 153. The tilt angle of the fourth reflector 154 relative to the plane of the front back panel is greater than the tilt angle of the third reflector 153 relative to the plane of the front back panel. The fifth reflector 155 is located above the second reflector 152 on the side near the rear back panel 140, and is tilted towards the front back panel, blocking the area above the fourth reflector 154. When the hot airflow rises, the fourth reflector 154 and the fifth reflector 155 act as air-gathering plates, collecting the heat and preventing heat loss, thus ensuring effective heat transfer. By setting the third reflector 153, the transition between the fourth reflector 154 and the corresponding second reflector 152 becomes smoother, which is more conducive to the hot airflow flowing towards the airflow outlet 120.

[0054] Figure 7 A cross-sectional view of an airflow driving device provided in an embodiment of the present invention is shown. (Refer to...) Figure 7The airflow drive device 200 includes a drive component and a fan 210. The drive component is disposed outside the housing 100. The fan shaft 211 of the fan 210 is tractively connected to the drive component. The drive component can drive the fan blades 212 of the fan 210 to rotate. The rotation plane of the fan blades 212 is parallel to the airflow outlet 120. The fan blades 212 include multiple fan blade bodies, forming an axial flow fan. Hot airflow can flow out from the airflow outlet 120 in a direction parallel to the fan shaft 211. In this embodiment, there are specifically four fan blade bodies. In other embodiments, there can be five or six fan blade bodies, etc. The more fan blade bodies there are, the greater the airflow.

[0055] With the above configuration, by utilizing the angle of attack (elevation angle) of the fan blade body, a local vacuum region can be formed on the right side of the fan blade 212 when the fan blade 212 rotates. Under the action of the pressure difference, the air on the right side of the fan blade 212 can be drawn into the left side of the fan blade 212, generating an airflow phenomenon and forming a forced airflow. In this embodiment, the driving component can specifically be a motor or the like, which is existing technology, and its structure and principle will not be described in detail here.

[0056] Reference Figure 3 and Figures 5-7 In this embodiment, the airflow drive device 200 includes a transmission belt 220 and a fan 210. The fan shaft 211 of the fan 210 is connected to the inner drum shaft 11 of the garment processing equipment via the transmission belt 220. When the garment processing equipment is started and the inner drum shaft 11 drives the inner drum 10 to rotate, it can drive the fan blades 212 of the fan 210 to rotate synchronously. The rotation plane of the fan blades 212 is parallel to the airflow outlet 120. With the above configuration, the rotation of the fan 210 can be achieved without additional drive components, thereby achieving the technical effect of making reasonable use of the kinetic energy generated by the rotation of the inner drum 10 to provide power for the fan 210.

[0057] Specifically, the airflow drive device 200 also includes a support base 230. The support base 230 is disposed within the housing 100, and the fan 210 is rotatably connected to the support base 230. By providing the support base 230, reliable support and mounting for the fan 210 can be provided.

[0058] More specifically, the airflow drive device 200 also includes a bearing 240. The support base 230 has a mounting hole 231, and the bearing 240 is disposed in the mounting hole 231. The fan shaft 211 is rotatably passed through the bearing 240 and connected to the fan blade 212. By providing the bearing 240, the smoothness and stability of the rotation of the fan blade 212 can be ensured.

[0059] Preferably, in this embodiment, the fan shaft 211 is formed by the coaxial fixed arrangement of a multi-ribbed pulley and a pin. The pin passes through the bearing 240 and is coaxially connected to the fan blade 212 using a washer 260 and a connecting bolt 250. The transmission belt 220 is wound around the multi-ribbed pulley.

[0060] More specifically, refer to Figure 3 , Figure 5 and Figure 6 The housing 100 contains a mounting platform 130. The rear panel 140 of the housing 100 has a C-shaped sheet metal structure facing inwards. The mounting platform 130 is formed on the upper surface of this C-shaped sheet metal structure and is located below the airflow outlet 120. The support 230 includes a support portion 232 and two mounting portions 233, each a block structure, protruding from opposite sides of the support portion 232 and capable of being fixed to the mounting platform 130 by bolts or the like.

[0061] Preferably, the fan 210 further includes an end cap 213, which is disposed at the end of the fan blade portion 212 away from the fan shaft 211. The end cap 213 is arc-shaped and protrudes relative to the end of the fan blade portion 212. With the above arrangement, the arc-shaped end cap 213 can guide the hot airflow to the fan blade position, reducing the resistance to the hot airflow.

[0062] Continue to refer to Figure 4 When the airflow outlet 120 is too small, the hot airflow entering the fan blade section 212 will be blocked by the back plate 140 when it exits the fan blade section 212, causing it to collide with the subsequent hot airflow and affecting the airflow outlet 120. Therefore, the area of ​​the fan blade section 212 is set to be smaller than the opening area of ​​the airflow outlet 120. With the above settings, the smooth airflow from the airflow outlet 120 can be achieved.

[0063] Specifically, the fan blade 212 is located at the geometric center of the airflow outlet 120. This arrangement improves the uniformity of airflow at the airflow outlet 120.

[0064] 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 will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. 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.
