Description

Technical Field

[0001] This application relates to the field of garment care technology, and in particular to a drying device. Background Technology

[0002] Clothes dryers and other drying equipment are common garment care devices. They typically use a condenser and evaporator as a heat exchange system for internal heat circulation. When hot, humid air is drawn from the drying drum and passes through the evaporator, the refrigerant absorbs heat from the air, lowering the air temperature and causing moisture to condense into water droplets. This effectively absorbs moisture from the air, and the condensed water drips down and is collected in a drip tray or discharged by a water pump. The compressor then pressurizes and heats the refrigerant, which enters the condenser to release heat. The condenser is connected to the airflow inside the dryer, outputting hot, dry air. This hot, dry air re-enters the drying drum, carrying away moisture from the clothes. This cycle achieves the drying of the garments. In this heat exchange process, the compressor, as the key component for pressurizing and heating the refrigerant, needs to work to generate heat. When the compressor temperature becomes too high, it enters a protection state and stops working, only resuming operation after cooling down. This increases the drying time for the user, resulting in a poor user experience.

[0003] Therefore, how to improve the high-temperature condition of the compressor, prevent the compressor from entering a protection state and stopping work, shorten the drying time, and improve the user experience are urgent problems to be solved.

[0041] In some embodiments, drying equipment such as clothes dryers uses a condenser and evaporator as a heat exchange system for internal heat circulation. When hot, humid air is drawn out of the inner drum and passes through the evaporator, the refrigerant absorbs heat from the air, lowering the air temperature and causing moisture to condense into water droplets. This effectively absorbs moisture from the air, and the condensed water drips down and is collected in a drip tray or discharged by a water pump. After the compressor pressurizes and heats the refrigerant, it enters the condenser to release heat. The condenser is connected to the air duct inside the dryer, outputting hot, dry air. This hot, dry air re-enters the inner drum, carrying away moisture from the clothes. This cycle dries the clothes. In this heat exchange process, the compressor, as the key component for pressurizing and heating the refrigerant, needs to work to generate heat. When the compressor temperature gets too high, it enters a protection state and stops working, only resuming operation after cooling down. This increases the drying time for users, resulting in a poor user experience. Therefore, how to improve the high-temperature state of the compressor, prevent it from entering a protection state and stopping, shorten the drying time, and improve the user experience is an urgent problem to be solved.

[0042] This disclosure provides a drying device 1, the structure of which is as follows: Figures 1 to 2 As shown, the drying equipment 1 mainly includes a housing 10 and a drum assembly 20. The drum assembly 20 includes a hollow cylindrical inner cylinder and a drive component (not shown). The inner cylinder is connected to the drive component and can rotate under the drive of the drive component. The inner cylinder is used to hold items to be dried, such as clothes.

[0043] The casing 10 is provided with a first air duct and a second air duct. The casing 10 is provided with an air inlet 121 and an air outlet. The first air duct connects the air inlet 121 and the air outlet (not shown). The first air duct is provided with a heat exchanger 30 and a compressor 50 arranged sequentially along its airflow direction. The heat exchanger 30 is at least able to exchange heat with the surrounding air to evaporate the refrigerant, thereby cooling the surrounding air. A fan 40 is also provided between the air inlet 121 and the compressor 50. The second air duct is used to form a circulation channel for the drying gas. The first air duct and the second air duct are independent of each other.

[0044] For details, please refer to Figures 1 to 4The drying gas used for drying clothes circulates in the second air duct. The evaporator 60 and condenser 70 are located within the second air duct. In this embodiment, a first air duct independent of the second air duct is provided. The gas in the first air duct is not connected to the gas in the second air duct. The heat exchanger 30 and compressor 50 are located within the first air duct, arranged sequentially along the airflow direction of the first air duct. A fan 40 is provided between the air inlet 121 and the compressor 50. Outside air enters the first air duct through the air inlet 121. Thus, the heat exchanger 30 cools the surrounding air, and the fan 40 blows the cold air towards the compressor 50, accelerating the flow of the cool air and rapidly cooling the high-temperature compressor. This ensures the compressor can operate continuously without stopping, reducing the overall drying time of the dryer and improving drying efficiency. After cooling the compressor, the air blown towards it is discharged from the first air duct through the air outlet, thus forming a complete air circulation. Figure 4 The direction indicated by the arrow BB in the middle is the airflow path within the first air duct.

[0045] In an optional embodiment, the heat exchanger can also exchange heat with its surrounding air to condense the refrigerant, thereby heating the surrounding air. Specifically, the heat exchanger 30, evaporator 60, and condenser 70 are provided with refrigerant channels connected in series. The condenser 70, heat exchanger 30, and evaporator 60 are arranged sequentially along the refrigerant flow direction. Throttling components are provided between the condenser 70 and the heat exchanger 30, and between the heat exchangers 30 and the evaporator 60. Under the action of the throttling components, the heat exchanger 30 achieves the switching between refrigerant evaporation and condensation, and exchanges heat with its surrounding air. It should be noted that the heat exchanger 30 is provided with a refrigerant channel, which is connected to the refrigerant channels of the evaporator 60 and the condenser 70. That is to say, although the heat exchanger 30 is located in the first air duct, which is independent of the second air duct, it participates in the evaporation and condensation of the refrigerant. During the process of evaporation and condensation of the refrigerant, the heat exchanger 30 needs to exchange heat with its surrounding air.

[0046] For example, along the refrigerant flow direction within the refrigerant channel, the condenser 70, heat exchanger 30, and evaporator 60 are connected in series. The refrigerant channel of the heat exchanger 30 is connected between the refrigerant channels of the evaporator 60 and the condenser 70. The flow rate of the refrigerant is adjusted by a throttling component, such as an electronic expansion valve, to switch between the evaporation and condensation functions of the heat exchanger 30. Since the condenser 70 and evaporator 60 are connected in series in the refrigerant channel, that is, while the condenser 70 is condensing the refrigerant to heat the drying gas in the second air duct, the evaporator 60 is also simultaneously evaporating the refrigerant and absorbing heat from the drying gas. Thus, the heating effect of the condenser 70 and the heat absorption effect of the evaporator 60 cancel each other out, resulting in slow heating of the drying gas and increasing the workload of the compressor 50. By installing a heat exchanger, on the one hand, when the heat exchanger is in the operation state of evaporating refrigerant, it absorbs heat from the outside air to achieve the evaporation of refrigerant. In this way, the amount of liquid refrigerant flowing into the evaporator can be reduced, thereby reducing the amount of refrigerant evaporating in the evaporator and thus reducing the heat absorbed by the evaporator from the drying gas. This improves the efficiency of the condenser in heating the drying gas, increases the heating speed of the drying gas, and reduces the workload of the compressor. On the other hand, when the heat exchanger is in the operation state of condensing refrigerant, the condenser and the heat exchanger condense the refrigerant simultaneously, thereby improving the efficiency of refrigerant condensation, reducing the load on the compressor, and thus reducing the possibility of the compressor overheating due to excessive load.

[0047] In addition to reducing the compressor load, this embodiment of the application further improves the high-temperature condition of the compressor by arranging the heat exchanger 30 and the compressor 50 sequentially along the airflow direction of the first air duct. A fan 40 is installed between the air inlet 121 and the compressor 50. Outside air enters the first air duct through the air inlet 121. Thus, when the heat exchanger 30 is in the working state of evaporating refrigerant, it absorbs heat from the surrounding air, achieving a cooling effect on the surrounding air. The fan 40 blows the cold air towards the compressor 50, accelerating the flow rate of the cooling air, thereby rapidly cooling the high-temperature compressor 50. It can be understood that, in addition to rapidly cooling the compressor 50, the fan 40 can also increase the flow rate of outside air through the heat exchanger 30, improving the heat exchange efficiency between the heat exchanger 30 and the outside air, thereby improving its efficiency in evaporating or condensing refrigerant.

[0048] It should be noted that, since the heat exchanger 30 can also be controlled to operate in a refrigerant condensation state, in this operating state, the heat exchanger 30 releases heat to the surrounding air. Although it cannot cool the surrounding air at this time, the surrounding air will heat up accordingly, but the temperature of the surrounding air is still lower than the temperature of the compressor 50 itself. Moreover, the fan 40 can accelerate the airflow speed in the first air duct and the circulation speed with the outside air, which can also cool the compressor 50 to a certain extent. Combined with the rapid cooling of the compressor 50 by the fan 40 in the refrigerant evaporation state of the heat exchanger 30, the compressor 50 can maintain a suitable low temperature throughout the entire operation process, avoiding shutdown caused by excessive temperature rise.

[0049] In an alternative embodiment, such as Figures 2 to 3 As shown, the housing 10 includes a front door 110, a rear panel 120, and a base 130. An air inlet 121 is located on the rear panel 120, and an air outlet (not shown) is located on the front door 110. The heat exchanger 30 and compressor 50 are located on the base 130. Specifically, the base 130 is located below the drum assembly 20, serving to support the entire device and house the main heat exchange components of the drying equipment 1. The base 130 has a frame structure, including a first support wall 131 corresponding to the rear panel 120 and a second support wall 132 corresponding to the front door 110. Both the first support wall 131 and the second support wall 132 are along the left-right direction. Figure 1 Extending along the Y-axis, the base 130 forms a accommodating cavity 133 between the first support wall 131 and the second support wall 132 for housing the evaporator 60 and the condenser 70. A sealing cover 134 is fixedly connected to the top of the accommodating cavity 133, thus forming a closed cavity. This allows the second air duct for drying gas to be independent of the first air duct. An open accommodating space is formed outside the closed cavity of the base 130. The heat exchanger 30, compressor 50, and fan 40 are all located within this open accommodating space, and the first air duct is also formed within this open accommodating space. The heat exchanger 30 and compressor 50 are fixed to the base 130 by fixing elements. With the above structure, the main heat exchange components of the drying equipment 1 can be reasonably arranged on the base 130, effectively utilizing the internal space of the base 130. Furthermore, the compressor 50 is positioned downstream of the heat exchanger 30 and fan 40, allowing the fan 40 to blow cooling gas towards the compressor 50 to cool it down.

[0050] It should be noted that while existing technologies may employ fans to cool the compressor, these fans are positioned near the front door, with airflow directed from the front to the rear of the drying equipment. Furthermore, the fans can only deliver room-temperature air to the compressor for cooling, resulting in a limited cooling effect. In this embodiment, the air inlet 121 is located on the rear panel 120, with airflow directed from the rear panel 120 to the front door 110. The fan 40 is positioned between the air inlet 121 and the compressor 50, directing the cooled air from the heat exchanger 30 towards the compressor 50, significantly enhancing the cooling effect.

[0051] In an alternative embodiment, such as Figures 2 to 3 As shown, the heat exchanger 30 is positioned near the air inlet 121, and the fan 40 is located between the heat exchanger 30 and the compressor 50. That is, the fan 40 is positioned downstream of the heat exchanger 30 and upstream of the compressor 50, which facilitates the flow of more cooled air to the compressor 50. Of course, in other alternative embodiments, the position of the fan 40 can be adaptively adjusted according to the specific layout of the components within the base 130, for example, positioned upstream of the heat exchanger 30 or on either side.

[0052] In one optional embodiment, the fan 40 is fixedly connected to the heat exchanger 30. Fixing the fan 40 to the heat exchanger 30 facilitates its installation and fixation, resulting in a compact structure and simplified base design. It also promotes the flow of gas around the heat exchanger 30. Further optionally, the fan 40 is fixed to the side of the heat exchanger 30 facing the compressor 50. It is understood that the fan 40 can also be fixed to other sides of the heat exchanger 30.

[0053] In an alternative embodiment, such as Figure 4 As shown, along the airflow direction of the first air duct, the compressor 50 is located in the middle of the base 130, and the air inlet 121, heat exchanger 30, compressor 50, fan 40, and air outlet are roughly on the same straight line. Specifically, the heat exchanger 30, compressor 50, and fan 40 are roughly arranged in a straight line. The air inlet 121 is located on the rear panel 120 corresponding to the positions of the heat exchanger 30, compressor 50, and fan 40, while the air outlet is located on the front door 110 corresponding to the positions of the heat exchanger 30, compressor 50, and fan 40. This arrangement ensures that the air inlet 121, heat exchanger 30, compressor 50, fan 40, and air outlet are all roughly on the same straight line, minimizing the airflow path in the first air duct and maximizing heat exchange efficiency. It also makes the layout of the heat exchange components more rational, with the evaporator 60 and condenser 70 located in the housing 133 on one side of the base 130, and the heat exchanger 30, compressor 50, and fan 40 on the other side, effectively utilizing the space of the base 130. The compressor 50 is located in the middle of the base 130, positioned as close as possible to the heat exchanger 30 and fan 40 to ensure good heat dissipation.

[0054] In one optional embodiment, the front door 110 and the rear panel 120 are respectively provided with a plurality of grid holes to form an air outlet and an air inlet 121. The elongated grid holes ensure both the aesthetics of the front door 110 and the rear panel 120 and a large airflow. In other optional embodiments, the air inlet 121 and the air outlet may also adopt a design such as a mesh-like circular hole.

[0055] In an alternative embodiment, such as Figures 5-7 As shown, the drying equipment 1 includes a fan hood 140, which has an air guide channel forming a second air duct. The fan hood 140 is located inside the housing 10, and a rear plate 120 covers the fan hood 140. It should be noted that in the existing drying equipment 1, the overall strength of the housing 10 is mainly ensured by the sheet metal rear plate 120, which provides support for components such as the drum assembly 20. The fan hood 140 is usually placed outside the housing 10, behind the rear plate 120. The fan hood 140 and the rear plate 120 together form a flow channel for the drying gas. The hot drying gas enters the inner cylinder of the drum assembly 20 through the air guide channel of the fan hood 140 to dry the items. However, due to the thermal conductivity of the sheet metal, the heat of the drying gas is significantly lost through the rear plate 120, which is not conducive to improving drying efficiency. In this embodiment, the air guide channel is located inside the hood 140. That is, the air guide channel is located independently of the rear plate 120 inside the hood 140, and the drying gas does not directly contact the rear plate 120 to avoid heat loss. In an optional embodiment, the hood 140 is made of plastic. Plastic has poor thermal conductivity, which can greatly reduce the heat loss of the drying gas inside the hood 140. Furthermore, by placing the hood 140 inside the housing 10 and covering the rear plate 120 with the hood 140, the hood 140 can serve as a supporting component to increase the strength of the housing 10. On the other hand, the hood 140 can also be used to install the drive component that drives the inner cylinder to rotate. This makes it easier to select a direct drive motor as the drive component, which can improve the motor's energy efficiency compared to the method of a motor driving a pulley to drive the inner cylinder to rotate. In addition, hiding the hood 140 inside the housing 10 also helps to improve the overall aesthetics of the drying equipment.

[0056] In an alternative embodiment, such as Figures 5-7As shown, the first support wall 131 has a first fixing part 1311 and a second fixing part 1312 along its length direction, and the closed cover plate 134 has an overlapping part 1341 located on one side of the rear plate 120. The overlapping part 1341 is fixed to the first fixing part 1311, and the wind cover 140 is fixed to the second fixing part 1312 and the overlapping part 1341. Specifically, the first support wall 131 extends along its length direction, i.e., the left-right direction, to match the width of the rear plate 120 in the left-right direction, thereby strengthening the overall fuselage. The first support wall 131 can also be used to fix the closed cover 134. For this purpose, the first support wall 131 is divided into a first fixing part 1311 and a second fixing part 1312 along its length direction. The closed cover 134 has an overlapping part 1341 located on one side of the rear plate 120. The overlapping part 1341 of the closed cover 134 is fixed to the first fixing part 1311 of the first support wall 131. Preferably, with the overlapping part 1341 fixed to the first fixing part 1311, the top of the overlapping part 1341 and the second fixing part 1312 together form a mounting surface of equal height to facilitate the installation of the hood 140, thereby fixing the hood 140 on the second fixing part 1312 and the overlapping part 1341. Of course, the top mounting surfaces of the overlapping part 1341 and the second fixing part 1312 may not be at the same height, and can be set according to the actual structural needs.

[0057] In an alternative embodiment, such as Figures 5-7 As shown, the wind cover 140 has a first support rib plate 141 and a second support rib plate 142 on both sides, and at least one limiting post 150 is provided on the second fixing part 1312 and the overlapping part 1341, respectively. The first support rib plate 141 and the second support rib plate 142 are respectively provided with limiting holes that are inserted into the limiting post 150.

[0058] Specifically, such as Figures 5-7As shown, the shroud 140 has a first air guide section 143 located at the top and a second air guide section 144 located at the bottom. The first air guide section 143 is generally disc-shaped, and the second air guide section 144 is generally irregularly square. The first air guide section 143 and the second air guide section 144 have interconnected air guide channels inside. The shroud 140 has a first support rib 141 and a second support rib 142 on both sides, which support the first air guide section 143 and the second air guide section 144. The first support rib 141 and the second support rib 142 both extend upward from the bottom of the second air guide section 144 to the first air guide section 143. The first support rib 141 is mainly located on the first support wall 13. On the second fixing part 1312 of 1, the second support rib 142 is located on the overlapping part 1341 of the closed cover plate 134. The first support rib 141 fills the entire gap between the first air guide part 143 and the second air guide part 144, and extends along the length direction of the first support wall 131 to the left end of the second fixing part 1312. That is, the first support rib 141 is widened enough to better ensure the overall structural strength of the wind cover 140. In this way, the first support rib 141, the second air guide part 144, and the second support rib 142 are adapted to the length of the first support wall 131, so that the wind cover 140 is stably supported on the base 130.

[0059] Furthermore, such as Figure 7 As shown, at least one limiting post 150 is provided on the second fixing part 1312 and the overlapping part 1341 respectively. The first supporting rib plate 141 and the second supporting rib plate 142 are respectively provided with limiting holes corresponding to the limiting posts 150 for insertion. Thus, during installation, the fan cover 140 can be initially positioned on the base 130 by insertion, and then fixed by fixing elements, thereby improving the convenience and accuracy of the fan cover 140 installation. Optionally, one limiting post 150 is provided on the second fixing part 1312, located at the left end of the second fixing part 1312; two limiting posts 150 are provided on the overlapping part 1341, located at both ends of the overlapping part 1341 respectively. In other alternative embodiments, the position and number of the limiting posts 150 on the second fixing part 1312 and the overlapping part 1341 can be flexibly adjusted according to specific needs. For example, two limiting posts 150 can be provided on the second fixing part 1312, and one limiting post 150 can be provided on the overlapping part 1341, etc.
