Description

Technical Field

[0001] The utility model relates to the technical field of clothes drying equipment, and specifically provides a clothes drying equipment. Background Art

[0002] The clothes drying equipment uses the drying airflow generated by the heat pump system to quickly dry the washed clothes. The heat pump system mainly includes a compressor, an evaporator, a condenser, and a capillary tube. During the operation of the clothes drying equipment, the heat pump system will accumulate a certain amount of heat, part of which is used to dry the clothes, while the other part will cause the temperature of the heat pump system to rise. In order to reduce the temperature of the various components of the heat pump system, a cooling fan is required to perform forced convection to achieve a cooling effect.

[0003] In the related art, an axial flow fan is generally installed next to the compressor. The characteristic of the axial flow fan is that the wind enters from the axial direction and then blows out from the axial direction. Although such a design can effectively reduce the temperature under normal circumstances, it is difficult to achieve a good cooling effect through the axial flow fan when the system resistance is large. Especially in the embedded dryer, the heat dissipation of the whole machine is more severe, and the heat cannot be dissipated through the vents on the back panel, which will seriously affect the working performance of the heat pump system and may even cause damage to the heat pump system components. .

[0004] In view of this, a new heat dissipation solution for clothes drying equipment is needed in the art to solve the above problems. Utility Model Content

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Clothes drying equipment uses the hot air flow generated by the heat pump system to complete the drying task. However, during the operation of the equipment, the heat pump system itself will generate a certain amount of heat, which needs to be dissipated in time to maintain the normal operating temperature of each component.

[0033] Generally, the heat dissipation of the drying device is to discharge the hot air to the outside through the ventilation duct by the heat dissipation fan 4, or to conduct the heat to the surface of the dryer shell through the heat dissipation plate. Generally, the ventilation duct is arranged on the rear plate or side plate of the housing 1, and the heat dissipation plate is arranged on the rear plate of the housing 1. However, such a heat dissipation scheme is not conducive to the heat dissipation of the embedded drying device.

[0034] Therefore, please refer to Figure 1-3 , which is a clothes drying device provided by an embodiment of the utility model. A drying component 3 is arranged in the clothes drying device, and the drying component 3 can also be understood as the above-mentioned heat pump system, which mainly includes a compressor 31, an evaporator, a condenser and a capillary tube, etc. The main function of these components is to provide a drying airflow for the clothes processing compartment of the drying device to complete the task of drying clothes.

[0035] A heat dissipation fan 4 is also provided inside the housing 1, and its function is to introduce external airflow into the housing 1 and flow through the surface of the components of the drying assembly 3 to take away the heat generated by each component.

[0036] Specifically, the housing 1 of the clothes drying device is provided with an air inlet and an air outlet 12. When the temperature of the drying component 3 exceeds a certain value and needs to be cooled, the heat dissipation fan 4 is started, and the airflow enters the housing 1 through the air inlet under the action of the heat dissipation fan 4, and then flows through the surfaces of the components of the drying component 3.

[0037] Since the temperature of the external airflow is lower than the temperature of the area where the drying component 3 is located, when the external airflow enters the interior of the housing 1 and contacts the components of the drying component 3 and the surrounding gas, heat exchange will occur between them. According to the heat exchange principle, heat will be transferred from the high temperature area to the low temperature area. In this case, the heat released by the drying component 3 will be absorbed by the external airflow, causing the temperature of the external airflow to rise. At the same time, the external airflow will also take away part of the high temperature gas around the drying component 3 under the action of the heat dissipation fan 4, and be discharged to the outside of the housing 1 through the air outlet 12, thereby reducing the temperature of the surface of the components of the drying component 3.

[0038] This heat exchange process keeps the temperature of the drying component 3 within a safe range, which helps maintain the stability and safety of the equipment.

[0039] Furthermore, an air outlet 12 is provided on the casing 1, and the air outlet 12 can be understood as a heat dissipation hole of the drying component 3. In the present embodiment, the air outlet 12 is arranged on the front surface of the casing 1, which not only enables the hot air flow to be discharged more directly to the outside of the casing 1 without the need for an additional ventilation system or duct, but also reduces the time that heat stays inside the device, thereby accelerating the heat dissipation process.

[0040] Furthermore, such a design is particularly helpful in improving the heat dissipation efficiency of the embedded clothes drying device, so that the clothes drying device can operate more effectively in different environments, thereby improving the heat dissipation performance and applicability of the clothes drying device.

[0041] In one embodiment, the air inlet 111 is disposed on the front surface of the housing 1 , and the input end 41 of the heat dissipation fan 4 is connected to the air inlet 111 , so that external air can enter the interior of the housing 1 through the air inlet 111 .

[0042] Specifically, there are many ways to connect the heat dissipation fan 4 to the air inlet 111, such as direct connection or pipe connection. In the direct connection, the input end 41 of the heat dissipation fan 4 can be directly toward the air inlet 111, and this connection method can simplify the structure.

[0043] In this embodiment, the connection between the input end 41 of the heat dissipation fan 4 and the air inlet 111 is preferably a pipeline connection.

[0044] Specifically, if Figure 3 As shown, an air guide portion 5 is connected between the input end 41 of the heat dissipation fan 4 and the air inlet hole 111. The air guide portion 5 is in the form of an air guide duct. The design of the air guide duct helps to guide the external airflow into the heat dissipation fan 4 through the air inlet hole 111, thereby improving the efficiency of the airflow.

[0045] Furthermore, the cross-sectional area of ​​the air guide duct gradually decreases along the direction from the air inlet hole 111 to the input end 41. The design of the gradually decreasing cross-sectional area of ​​the air guide duct takes into account the small size of the input end 41 of the heat dissipation fan 4, while the air inlet hole 111 is designed to be large, so as to ensure that the two are effectively connected while maintaining sufficient air intake.

[0046] Furthermore, by gradually reducing the cross-sectional area of ​​the structure, the airflow velocity can be increased to a certain extent, thereby optimizing the airflow path, and the heat dissipation efficiency can also be improved to a certain extent.

[0047] In one embodiment, if Figure 1 and 2 As shown, the air inlet 111 and the air outlet 12 are located at the same height, or, it can be understood that the air inlet 111 and the air outlet 12 are arranged side by side on the front surface of the casing 1, forming a U-shaped heat dissipation duct structure, and the heat dissipation fan 4 is connected and arranged in the duct structure.

[0048] This U-shaped air duct design can optimize the airflow path, allowing the airflow to circulate more effectively around the drying component 3, which helps to improve the heat exchange efficiency between the drying component 3 and the external airflow.

[0049] At the same time, arranging the air inlet 111 and the air outlet 12 side by side on the front surface of the casing 1 can not only simplify the structural design, but also make better use of the space on the front surface of the casing 1, making the heat dissipation structure more compact.

[0050] In one embodiment, the drying assembly 3 is located at the upper portion of the housing 1 , and the air inlet 111 and the air outlet 12 are located at the upper portion of the housing 1 .

[0051] In this way, the heat dissipation structure is concentrated in the same area, and the air inlet 111 and the air outlet 12 are arranged side by side on the front surface of the casing 1 and close to the area, so that the heat dissipation structure of the drying component 3 is more concentrated, and the heat can be more effectively conducted and discharged, thereby improving the heat dissipation efficiency.

[0052] In one embodiment, the cross-sectional area of ​​the air inlet 111 is larger than the cross-sectional area of ​​the air outlet 12. Since the cross-sectional area of ​​the air outlet 12 is smaller, the speed of the airflow outflow is relatively reduced, so that the airflow stays longer when in contact with the drying component 3, which is conducive to extending the heat exchange time between the airflow and the drying component 3, thereby improving the effect of heat exchange.

[0053] In a preferred embodiment, the air inlet 111 and the air outlet 12 are preferably strip holes. The strip holes can not only provide a more uniform airflow distribution, but also have a more modern and beautiful structure, which can enhance the texture of the overall product appearance and meet the user's demand for a beautiful product appearance.

[0054] In one embodiment, the heat dissipation fan 4 is preferably a centrifugal fan. A centrifugal fan has significant advantages over an axial flow fan. First, it can generate a higher air flow pressure; second, a centrifugal fan has a compact structure and occupies a small space, which is suitable for equipment with limited space such as a clothes dryer.

[0055] Furthermore, in the present embodiment, the centrifugal fan is preferably a double-inlet centrifugal fan, that is, the centrifugal fan has two input ends 41, namely a first input end and a second input end (not shown in the figure).

[0056] The first input end is connected to the air inlet hole 111 through the air guide portion 5 , and is used to inhale the air flow entering the housing 1 from the air inlet hole 111 .

[0057] The second input end faces the inside of the casing 1 and is used to inhale the airflow inside the casing 1, which helps to increase the flow of the gas inside the casing 1 and improve the circulation efficiency of the gas inside the casing 1. In addition, such a structure also helps the heat dissipation fan 4 to take away the humid airflow inside the casing 1, thereby improving the drying efficiency of the clothes drying device.

[0058] In summary, this design allows the centrifugal fan 4 to operate more efficiently through two air inlet ends, optimizing the gas environment inside the housing 1. This not only improves the heat dissipation performance of the clothes drying device, but also ensures the gas circulation inside the housing 1, effectively discharges the humid airflow, thereby improving the overall drying efficiency and heat dissipation performance.

[0059] In one embodiment, the clothes drying device further includes an air guide plate 6 which is disposed in the housing 1 , and the air guide plate 6 is located between the output end 42 of the heat dissipation fan 4 and the air outlet 12 .

[0060] By setting the air guide plate 6, the direction of the hot air flow can be effectively controlled to avoid the accumulation or dead corner of the hot air flow inside the casing 1, so that the hot air flow can be smoothly transported to the outside of the casing 1, ensuring smooth ventilation of the heat dissipation duct, which is conducive to improving the heat dissipation efficiency.

[0061] In one embodiment, the air guide plate 6 is preferably an arc-shaped plate, and the concave surface of the arc-shaped plate faces the compressor 31 of the drying component 3 .

[0062] Specifically, by turning the concave surface of the air guide plate 6 toward the compressor 31 of the drying assembly 3, more airflow can be effectively guided to flow around the compressor 31, thereby increasing the air volume around the compressor 31, improving its heat exchange efficiency, and thereby improving the heat dissipation efficiency of the compressor 31.

[0063] In another embodiment, the air guide plate 6 is disposed in the housing 1 and is located between the air inlet 111 and the air outlet 12 (not shown in the figure).

[0064] Specifically, when the external airflow enters the housing 1, the air guide plate 6 can guide the airflow to ensure that the airflow can flow smoothly after entering the housing. At the same time, when the hot airflow in the housing 1 needs to be discharged, the air guide plate 6 can also guide the hot airflow to be discharged smoothly outside the housing 1.

[0065] With this design, the air guide plate 6 guides the airflow both during the air intake and air discharge processes, which helps to simplify the internal structure of the housing 1 .

[0066] In addition, the airflow can flow more efficiently through the guidance of the air guide plate 1, thereby optimizing the airflow path of the entire system. This not only improves the circulation efficiency of the gas and ensures the stability of the gas flow, but also helps to improve the overall heat dissipation efficiency, thereby improving the performance and service life of the clothes drying device.

[0067] Furthermore, the concave surface of the air guide plate 6 faces the air inlet direction. Such a design helps to increase the air inlet volume to a certain extent, introduces more external airflow into the casing 1, and thus improves the heat dissipation efficiency and performance of the clothes drying device.

[0068] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
