Description

Technical Field

[0001] The present application relates to the field of clothing processing equipment, and specifically provides a drying equipment. Background Art

[0002] Gas clothes dryers are mainly used to dry clothes. Their structure mainly includes a combustion chamber, a fan chamber, an inner drum and an air duct. The working principle of a gas clothes dryer is: the air is heated in the combustion chamber to generate hot air (flow), and the fan chamber sucks air to put the inner drum in a negative pressure state, so that the hot air flow enters the inner drum and comes into contact with the clothes in the inner drum to dry the clothes. The moisture generated by the drying process can be carried away through the air duct.

[0003] Among them, the combustion chamber will have a great impact on the drying effect of the gas dryer. Specifically, the current combustion chamber mainly includes a fan and a reflector. The hot air is sucked in by the fan and reflected by the reflector before entering the inner cylinder through the air inlet. The suction efficiency is low, and the hot air flow after reflection by the reflector has the problem of unconcentrated air intake. In addition, the increase of the reflector means that the volume in the combustion chamber is reduced, and the volume of gas that can be accommodated will naturally be reduced, which is not conducive to the flow of hot air. In addition, the hot air flow is prone to generate vortices at the bend of the reflector, which will increase the gas resistance and affect the thermal cycle of the combustion chamber.

[0004] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0005] The present application aims to at least partially solve the above technical problems. Specifically, it provides a method that can at least to some extent improve the problems of current drying equipment such as unconcentrated air intake and easy generation of vortexes due to the guidance of the reflector.

[0006] In view of this, the present application provides a drying device, which includes a device body, the device body including an inner cylinder, a fan chamber and a combustion chamber; wherein, a first fan is provided in the fan chamber, and under the suction action of the first fan, air can flow along the combustion chamber, the inner cylinder, the fan chamber and the combustion chamber in sequence to form a closed loop path; wherein, a guide part is provided in the combustion chamber, and the guide part includes: a first guide part, the first guide part includes a reflective plate, and the reflective plate can guide the air delivered from the fan chamber to the combustion chamber; and a second guide part, which can guide the air in the combustion chamber to the inner cylinder by cooperating with the first guide part.

[0007] With this configuration, the first guide portion and the second guide portion cooperate to guide the air in the combustion chamber to the inner drum, thereby drying the clothes to be dried placed in the inner drum.

[0008] As mentioned in the background, the installation of reflectors alone often leads to problems such as poorly concentrated air intake and the generation of eddies. The second guide portion can mitigate or even eliminate these issues, thereby improving the quality of the hot airflow entering the inner drum of the drying device. This, in turn, is expected to ensure more complete contact between the hot airflow and the clothes being dried, thereby enhancing the performance of the drying device.

[0009] It is understandable that those skilled in the art can determine the structure, number, location and corresponding reflection path of the reflective plates to the air according to actual needs.

[0010] In addition, those skilled in the art can determine the structural form, number, setting position of the second guide part and its cooperation with the reflector according to actual needs. For example, the air delivered from the fan chamber to the combustion chamber can be guided before, at the same time or after the air flows through the first guide part, thereby improving the state of the hot air flow entering the inner barrel.

[0011] For the above drying device, in a possible implementation manner, the second guide portion is provided at least on the downstream side of the reflection plate.

[0012] With this structure, it is possible to achieve a method of supplementarily guiding the hot air flow into the inner tube through the second guiding portion after the guidance of the reflector plate is basically completed.

[0013] For the above drying device, in a possible implementation manner, the second guide part includes a second fan.

[0014] This configuration provides a possible structural form of the second guide part.

[0015] It is understandable that those skilled in the art can determine the structure of the second fan, its fixing method in the combustion chamber, and its relative position to the reflector plate according to actual needs.

[0016] For the above drying device, in a possible implementation manner, the second fan is an axial flow fan, and the axis of the axial flow fan is substantially parallel to the axis of the inner cylinder.

[0017] With this configuration, it is possible to supply linear, concentrated hot air flows to the inner cylinder by the axial flow fan.

[0018] For the above-mentioned drying device, in a possible implementation manner, the axial flow fan can rotate with the help of the force generated by the first fan guiding the air; or the axial flow fan is equipped with a driving component, and the driving component can drive the axial flow fan to rotate.

[0019] Through such a configuration, it is possible to selectively configure the power source for the axial flow fan according to actual needs. For example, in the case of insufficient air power, the driving component can be used as a supplement to ensure the reliability of air flow guidance.

[0020] For the above drying apparatus, in a possible implementation, the reflection plate has a reflection surface, and the axis of the axial flow fan and the reflection surface form an included angle.

[0021] Through such a configuration, it is possible to disperse the vortex generated in the combustion chamber due to the presence of the reflection plate, thereby ensuring the circulation effect of the hot air flow.

[0022] It can be understood that those skilled in the art can determine the size of the included angle according to actual needs. For example, the included angle between the reflection plate near the axial flow fan and the horizontal plane is 45-60° (tilted away from the axial flow fan), and the axis of the inner cylinder and the axial flow fan are substantially parallel and horizontally arranged, so that the included angle between the axis of the axial flow fan and the reflection surface is 45-60°.

[0023] For the above drying apparatus, in a possible implementation, the second fan includes a fan blade assembly and a connecting assembly, and the fan blade assembly is pivotally arranged in the combustion chamber through the connecting assembly.

[0024] Through such a configuration, a possible structure of the second fan is given.

[0025] It can be understood that those skilled in the art can determine the specific form of the connecting assembly and the specific position of the fan blade assembly arranged in the combustion chamber according to actual needs. For example, the connecting assembly is a combination of a mounting plate and a mounting shaft, a combination of a shaft and a shaft sleeve, etc.

[0026] For the above drying apparatus, in a possible implementation, the connecting assembly includes a fixing assembly including a pin shaft penetrating the fan blade assembly and a bolt, and a bearing assembly including a bearing seat and a bearing arranged in the bearing seat. The bearing seat is arranged in the combustion chamber, the pin shaft penetrates the bearing, and thus the fan blade assembly and the bearing seat are rotationally connected.

[0027] Through such a configuration, a possible structure of the connecting assembly is given.

[0028] For the above drying apparatus, in a possible implementation, the fan blade assembly has a hollowed-out area at the end away from the inner cylinder, the fan blade assembly is provided with an end cover at a position corresponding to the hollowed-out area, and at least a part of the bolt is accommodated in the hollowed-out area.

[0029] Through such a configuration, it is possible to effectively protect the connecting assembly on the basis of weight reduction.

[0030] For the above drying apparatus, in a possible implementation, the bearing seat is fixedly arranged on the shell of the combustion chamber or the reflecting plate in the combustion chamber.

[0031] Through such a configuration, a possible fixing mode of the bearing seat is given.

[0032] It can be understood that a person skilled in the art can determine the structure of the bearing seat and the specific fixing mode thereof with the shell of the combustion chamber or the reflecting plate in the combustion chamber according to actual needs. For example, the fixed connection between the two can be achieved by single-point connection or multi-point connection. Taking multi-point connection as an example, a person skilled in the art can determine the specific connection mode of multi-point connection and the positional relationship between the connection points according to actual needs. Exemplarily, the multi-point connection includes two connection modes of welding and screwing.

[0033] In the preferred embodiment of the present application, by adding a second fan at the gas outlet of the combustion chamber, double-power air intake based on the first fan in the fan chamber and the second fan in the combustion chamber can be achieved. In this way, on the premise that there are problems such as air intake not being concentrated and vortex being easily generated when only the reflecting plate as the first guide part guides the hot air flow, supplementary guidance by the second fan can be achieved to ensure the hot air flow guiding quality of the drying apparatus.

[0034] Specifically, on the one hand, the second fan is arranged in the combustion chamber, which can forcibly change the flow direction of the hot air flow generated in the combustion chamber, thereby expectedly improving the circulation efficiency of the hot air flow. Specifically, by dispersing the vortex generated in the combustion chamber, the hot air flow is forcibly introduced into the inner cylinder along the guide path based on the second fan. On the other hand, in the case that the hot air flow enters the fan blade assembly inside the second fan, the fan blade assembly is guided to do centrifugal motion under the guidance of the fan blade, thereby accelerating the hot air flow. In this way, the hot air flow entering the inner cylinder can be more concentrated. On this basis, by combining the reflecting plate as the first guide part with the second fan as the second guide part, the hot air flow entering the inner cylinder can more fully contact the clothes to be dried, thereby improving the drying efficiency of the drying apparatus and optimizing the use performance of the drying apparatus.

[0053] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0054] For example, although in this embodiment, the number / position / reflection angle of the reflective plates is not introduced in more detail, and the combination of multiple reflective plates and a second fan is used as an example for explanation, it is obvious that those skilled in the art can flexibly adjust the guiding effect based on the reflective plates according to implementation requirements, such as adjusting the number and installation angle of the reflective plates according to the second fan.

[0055] For example, although in this embodiment, the second fan is a non-powered mechanism, specifically, the suction force of the first fan on the air serves as the rotational power of the second fan, and no power source is provided for the second fan, those skilled in the art can, however, configure the second fan with a driving component such as a motor according to actual needs to ensure reliable guidance of the thermal airflow.

[0056] For example, although in this embodiment, the second fan is pivotally connected relative to the combustion chamber via a combination of a pin and bolt, a bearing, and a bearing seat, it is apparent that those skilled in the art can flexibly adjust the pivotal connection method of the second fan according to actual needs. Furthermore, drive components such as a motor can be configured to ensure reliable guidance of the hot air flow.

[0062] In addition, in order to better illustrate the present application, numerous specific details are provided in the following detailed description. Those skilled in the art will understand that the present application can still be implemented without certain specific details. In some examples, the principles of drying equipment well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0063] In a possible embodiment, the drying device 100 of the present application includes a device body, which includes a combustion chamber 1, an inner drum 2, an air duct 3, and a fan chamber 4 that are connected in sequence along the flow direction of the hot air flow and form a closed loop. For example, in this example, the inner drum 2 is located at the upper left, the air duct 3 is located at the lower left, the fan chamber 4 is located at the lower right, and the combustion chamber 1 is located at the upper right. Among them, the combustion chamber 1 is provided with a heating component 11 that can heat the air to generate hot air (flow) and a reflector 12 that emits the hot air flow so that it reaches the inner drum. The inner drum 2 can hold clothes to be dried. The fan chamber 4 is provided with a first fan 41. The first fan 41 sucks air so that the inner drum 2 forms a negative pressure state. Under the guidance of the first fan 41, the air enters the bottom of the combustion chamber 1 and is heated. The heated hot air flow enters the inner drum and contacts the clothes to be dried contained in the inner drum 2, thereby drying them. During the drying process, the humid air can be taken away through the air duct 3.

[0064] In the present application, a second fan 5 is added to the combustion chamber 1 near its air outlet. In this way, under the suction action of the first fan 41 located in the fan chamber 4, the second fan 5 is driven to rotate, thereby providing power for the second fan 5. In this way, the flow of hot air flow can be promoted, thereby improving the circulation efficiency of the hot air flow.

[0065] In one possible embodiment, the second fan 5 is an axial flow fan, the axis of the axial flow fan is roughly parallel to the axis of the inner cylinder, and the hot air flow can enter the inner cylinder along the axial direction of the axial flow fan. For example, in this example, the second fan 5 is arranged on the right side of the inner cylinder 2. In this way, when the second fan 5 is in operation, the angle of attack (elevation angle) of the blades of the second fan itself is used to form a local vacuum in the area to the right of the blades of the second fan. Due to the pressure difference, the air on the right side of the blades is sucked into the left side of the blades, thereby generating an air flow and forming a forced airflow. Since the direction of the hot air flow is parallel to the axis of the axial flow fan, the hot air flow will enter the blades along the central axis of the blades and flow out to the inner cylinder along the central axis of the blades.

[0066] In one possible embodiment, the second fan 5 mainly includes a blade assembly 51, which includes a plurality of blades, and the blade assembly is pivotally arranged at a position of the device body corresponding to the combustion chamber 1. In this example, the blade assembly is provided with a pin 52 at its axial position, and the pin is arranged on a bearing seat 532 fixedly arranged in the combustion chamber through a bearing 531. Specifically, after the bearing 531 is pressed onto the bearing seat 532, the pin 52 is passed through the blade assembly 51, and the blade assembly 51 is fixed to the bearing 531 through a gasket 54 and a bolt 55, so that the blade assembly 51 can rotate relative to the bearing seat 532 together with the bearing 531. In addition, in order to reduce the weight of the second fan as much as possible, the portion of the blade assembly close to the right side is hollowed out (having a hollowed-out area), and an end cover 56 is added at the end to protect the bolt 54 and the gasket 55. Considering the installation position of the second fan in the drying equipment and its working environment, the fan blade assembly and the end cover should be supported by high-temperature resistant metal materials. For example, the end cover can be directly connected to the end of the fan blade assembly away from the inner cylinder in a removable manner such as a snap-on type.

[0067] In one possible implementation, the fan blade assembly's radial dimensions should approximate the circumferential dimensions of the inner cylinder's air inlet 21 to ensure high-quality airflow guidance. For example, if the inner cylinder's air inlet is roughly rectangular, the fan blade assembly's radial dimensions (diameter) should be no greater than the height and width of the rectangular structure. Furthermore, the fan blade assembly typically has more than three blades to ensure sufficient airflow capacity for the second fan.

[0068] As in this example, the entire structure of the second fan can be secured to the combustion chamber's reflector plate using fasteners such as mounting bolts 6. Specifically, the bottom of the bearing housing has two mounting locations, which are used to secure the second fan to the combustion chamber. When installed, the second fan's blade assembly is roughly located in the middle of the combustion chamber's air outlet. This allows hot air to enter the inner barrel more quickly along the axial direction of the blade assembly. Alternatively, the second fan can be secured to other structures / locations, such as the combustion chamber's casing.

[0069] As mentioned in the background, hot air flows tend to generate vortices at the bends of the reflector, increasing gas resistance and thus affecting the thermal cycle in the combustion chamber. Specifically, vortices form in the combustion chamber when the hot air encounters obstacles, such as the reflector, that alter its velocity and direction. Within the combustion chamber, the hot air forms vortices within the reflector and the housing that forms the combustion chamber, thus affecting its circulation.

[0070] In a preferred embodiment of the present application, a second fan is provided, and the power of the second fan disperses the vortex generated in the combustion chamber, forcibly introducing the hot air flow into the inner drum based on the guide path of the second fan, thereby improving the circulation efficiency of the hot air flow. Moreover, based on the power provided by the second fan, when the hot air flow enters the fan blade assembly inside the second fan, it performs centrifugal motion under the guidance of the fan blades of the fan blade assembly, thereby accelerating the hot air flow. In this way, the hot air flow can reach the tube mouth of the inner drum faster, and the hot air flow entering the inner drum is more concentrated. Based on this, it is expected that the hot air flow entering the inner drum can more fully contact the clothes to be dried, thereby improving the drying efficiency.

[0071] It is understandable that, although in this embodiment, the power of the second fan comes only from the force generated by the first fan guiding the air, it is obvious that a separate power (such as a blower, etc.) can also be added to the second fan to better guide the circulation of the hot air flow.

[0072] In addition, it can be understood that although in this embodiment, multiple reflective plates and a second fan are provided in the combustion chamber and the second fan is arranged at a position close to the air outlet of the combustion chamber, it is obvious that those skilled in the art can determine the specific combination of the reflective plate and the second fan according to actual needs, such as one reflective plate and multiple second fans.

[0073] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
