Description
Technical Field
[0001] This utility model relates to the field of clothing processing technology, specifically providing a drying device and clothing processing equipment including the drying device. Background Technology
[0002] With the development of technology and the improvement of people's living standards, clothing processing equipment such as drum washing machines or dryers with drying functions have become increasingly popular.
[0003] Taking a clothes dryer as an example, the existing clothes dryer has a drying drum and a drying device in its casing. Taking a heat pump drying device as an example, the drying device mainly includes a heat pump system, a fan, and a drying duct. The heat pump system mainly includes a compressor installed outside the drying duct and an evaporator and a condenser installed in the drying duct. The evaporator is used to condense and dehumidify the airflow in the drying duct, and the condenser is used to heat the airflow in the drying duct. The drying duct is connected to the drying drum, and the airflow circulates between the drying drum and the drying duct under the action of the fan.
[0004] The drying process of clothes in a dryer can be divided into two processes: moisture evaporation and water vapor condensation. Air is heated into dry hot air by the condenser of the heat pump system and enters the drying drum. The dry hot air passes through the wet clothes, and the moisture on the clothes absorbs heat and vaporizes into humid hot air. The humid hot air is converted into dry cold air after passing through the evaporator of the heat pump system. The water vapor in the air condenses into water droplets and is separated. The dry cold air is then heated by the condenser and enters the drying drum again. This cycle continues until the wet clothes are dried.
[0005] However, as the ambient temperature inside the system increases, the heat exchange capacity of the evaporator decreases. Furthermore, as the humidity of the clothes decreases, the relative humidity of the humid air discharged from the dryer also decreases, leading to a decline in the evaporator's dehumidification efficiency and affecting drying efficiency, resulting in longer drying times. Current technologies typically improve dehumidification efficiency by increasing the compressor displacement or the evaporator area, but these methods are less effective and suffer from high energy consumption and inconvenient evaporator installation.
[0006] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content
[0007] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem of long drying time in existing clothing processing equipment.
[0008] In a first aspect, the present invention provides a drying device, the drying device comprising a drying air duct and a dehumidifying component, a heating component, and an electrode assembly installed in the drying air duct, wherein, along the airflow direction, the dehumidifying component is located upstream of the heating component and downstream of the electrode assembly.
[0009] The electrode assembly includes a power supply component, a fixing component, and a plurality of spaced first needle-shaped electrodes mounted on the fixing component. The power supply component is connected to the first needle-shaped electrodes and is capable of supplying power to the first needle-shaped electrodes. The first needle-shaped electrodes are capable of ionizing air to generate negative ions and extend toward the dehumidification component.
[0010] In the preferred embodiment of the above-mentioned drying device, the plurality of first needle-shaped electrodes are divided into multiple groups of electrodes, each group of electrodes including a plurality of first needle-shaped electrodes spaced apart along a first direction, the multiple groups of electrodes being spaced apart along a second direction, the first direction being perpendicular to the second direction.
[0011] In the preferred embodiment of the drying device described above, the plane in which the plurality of first needle electrodes are located is perpendicular to the flow direction of the airflow in the drying duct.
[0012] In the preferred embodiment of the above-mentioned drying device, the first needle-shaped electrode extends toward the dehumidifying member along a third direction, and the third direction is perpendicular to both the first direction and the second direction.
[0013] In the preferred embodiment of the above-mentioned drying device, the electrode assembly further includes a plurality of spaced second needle-shaped electrodes mounted on the fixed member. The power supply member is also connected to the second needle-shaped electrodes and is able to supply power to the second needle-shaped electrodes. The second needle-shaped electrodes are also able to ionize air to generate negative ions. The extension direction of the second needle-shaped electrodes intersects with the extension direction of the first needle-shaped electrodes.
[0014] In the preferred embodiment of the drying apparatus described above, the extension direction of the second needle electrode is perpendicular to the extension direction of the first needle electrode.
[0015] In the preferred embodiment of the above-mentioned drying device, the fixing component includes a first fixing component and a second fixing component detachably mounted on the first fixing component. The first fixing component is connected to the dehumidifying component, and the second fixing component is spaced apart from the dehumidifying component. The first needle-shaped electrode is mounted on the second fixing component.
[0016] In the preferred embodiment of the above-mentioned drying device, the first fixing member includes a first fixing plate and a second fixing plate disposed opposite to each other. The first fixing plate has a first insertion groove on the side facing the second fixing plate, and the second fixing plate has a second insertion groove on the side facing the first fixing plate. The two edges of the second fixing member are respectively inserted into the first insertion groove and the second insertion groove; and / or
[0017] The second fixing component is a rectangular frame.
[0018] In the preferred embodiment of the above-mentioned drying device, the drying device further includes a heat pump system, wherein the evaporator of the heat pump system is the dehumidification component, and the condenser of the heat pump system is the heating component.
[0019] In a second aspect, the present invention also provides a garment processing device, which includes the aforementioned drying device.
[0020] Those skilled in the art will understand that the drying device of this invention adds an electrode assembly in the drying duct and positions the electrode assembly upstream of the dehumidification component. The electrode assembly includes a power supply component and multiple spaced-apart first needle-shaped electrodes. The power supply component is connected to the first needle-shaped electrodes and can supply power to the first needle-shaped electrodes. The first needle-shaped electrodes can ionize the air to generate negative ions. These negative ions can become additional condensation nuclei in the humid air. Condensation nuclei are the attachments of water vapor condensation. The increased number of condensation nuclei in the humid air increases the amount of water condensed when the humid air flows through the dehumidification component, thereby improving the dehumidification efficiency of the dehumidification component and the drying efficiency of the drying device. This helps to reduce drying time and improve the user experience. In addition, by extending the first needle-shaped electrodes toward the dehumidification component, it is beneficial for negative ions to flow toward the dehumidification component, which further improves the dehumidification efficiency.
[0021] Furthermore, by dividing the multiple first needle-shaped electrodes into multiple groups of electrodes, each group of electrodes includes multiple first needle-shaped electrodes spaced apart along a first direction, and the multiple groups of electrodes spaced apart along a second direction, the coverage area of the multiple first needle-shaped electrodes can be further increased, allowing for more sufficient contact with the airflow, thereby increasing the number of negative ions generated.
[0022] Furthermore, by aligning the plane containing the multiple first needle-shaped electrodes with the flow direction of the airflow in the drying duct, this invention enables the airflow to come into more full contact with the multiple first needle-shaped electrodes, thereby ionizing and generating more negative ions.
[0023] Furthermore, this invention provides multiple spaced second needle-shaped electrodes on a fixed component. Both the first and second needle-shaped electrodes can ionize air to generate negative ions, and the first and second needle-shaped electrodes extend in different directions, which helps to ionize the electrode assembly to generate more negative ions.
[0024] Furthermore, by making the second fixing component detachably mounted on the first fixing component and the first needle-shaped electrode mounted on the second fixing component, this utility model facilitates the removal of the first needle-shaped electrode for inspection or replacement.

[0032] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the following embodiments are described in conjunction with a clothes dryer, the technical solution of the present invention is equally applicable to other clothing processing equipment, such as washer-dryer combos.
[0033] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0034] Specifically, such as Figure 1 As shown, this utility model provides a clothes dryer, which includes a drying drum 1, a drying air duct 2, a heat pump system 3, and an electrode assembly 4. The drying air duct 2 is connected to the drying drum 1. The heat pump system 3 includes an evaporator 31 and a condenser 32 installed in the drying air duct 2. Along the airflow direction, the evaporator 31 is located upstream of the condenser 32. The electrode assembly 4 is installed in the drying air duct 2. Along the airflow direction, the electrode assembly 4 is located upstream of the evaporator 31. The electrode assembly 4 is capable of ionizing air to generate negative ions.
[0035] The dryer provided by this utility model heats the air through the condenser 32 of the heat pump system 3 and delivers hot dry air to the drying drum 1 through the drying duct 2 for drying clothes. The hot dry air passes through the wet clothes, and the moisture on the clothes absorbs heat and vaporizes into hot humid air that enters the drying duct 2. When the hot humid air flows through the electrode assembly 4, it is ionized to generate negative ions. The negative ions can become condensation nuclei for water molecules in the air. The increase in condensation nuclei increases the amount of condensation. In this way, when the hot humid air flows through the evaporator 31, it can form more condensate, thereby improving the dehumidification efficiency of the evaporator 31, which is beneficial to improving the drying efficiency of the dryer and reducing the drying time.
[0036] It should be noted that, in practical applications, those skilled in the art may omit the heat pump system 3 and instead use other types of dehumidifying and heating components to replace the evaporator 31 and condenser 32 for dehumidifying and heating the airflow in the drying duct. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should be limited to the protection scope of this utility model. Of course, this utility model preferably uses the heat pump system 3 to dehumidify and heat the airflow in the drying duct.
[0037] Preferably, such as Figures 2 to 4 As shown, the electrode assembly 4 of this utility model includes a power supply component (not shown in the figure), a fixing component 41, and a plurality of first needle-shaped electrodes 42 spaced apart and mounted on the fixing component 41. The power supply component is connected to the first needle-shaped electrodes 42 and can supply power to the first needle-shaped electrodes 42. The first needle-shaped electrodes 42 can ionize the air to generate negative ions. The first needle-shaped electrodes 42 extend toward the evaporator 31 (i.e., the dehumidification component).
[0038] The fixing component 41 serves as the mounting base for the entire electrode assembly 4. It can be connected to the drying air duct 2 or the evaporator 31. The first needle-shaped electrode 42 is mounted on the fixing component 41. There are multiple first needle-shaped electrodes 42, which can increase the contact area with air, resulting in higher ionization efficiency and the generation of more negative ions, thus improving dehumidification efficiency. In addition, the first needle-shaped electrode 42 extends toward the evaporator 31, which facilitates the flow of negative ions toward the evaporator 31, further improving dehumidification efficiency.
[0039] For example, the power supply component is a high-voltage transformer, which is also mounted on the fixed component 41. The first needle-shaped electrode 42 is a key component for generating negative ions. When a high-voltage current passes through the first needle-shaped electrode 42, the first needle-shaped electrode 42 can ionize the air to generate negative ions. The high-voltage transformer is used to provide high-voltage direct current to the first needle-shaped electrode 42. The high-voltage transformer is a device for generating high-voltage electrical energy, ensuring a stable and continuous power supply to the first needle-shaped electrode 42. After the humid and hot air enters the drying duct 2, when it flows through the electrode assembly 4, the high-voltage transformer provides high-voltage direct current to the first needle-shaped electrode 42, causing the first needle-shaped electrode 42 to ionize the air and generate negative ions. These negative ions become additional condensation nuclei in the humid and hot air. Condensation nuclei are the attachments for water vapor condensation. Therefore, the negative ions increase the number of condensation nuclei in the air, which is more conducive to the condensation of water vapor in the humid and hot air, thereby improving the dehumidification efficiency of the evaporator 31, and thus improving the drying efficiency of the dryer and reducing the drying time.
[0040] For example, in this invention, the high-voltage transformer provides a high-voltage direct current (DC) voltage between 5KV and 12KV to the first needle-shaped electrode 42, thereby ensuring a sufficiently strong ionization effect and generating a sufficient number of negative ions to enhance the condensation of moisture in the humid air. Of course, in other embodiments, the voltage of the DC power supplied by the high-voltage transformer can be adjusted according to actual dehumidification requirements to achieve the optimal dehumidification effect of the clothing treatment equipment. For example, the voltage of the DC power supplied by the high-voltage transformer to the first needle-shaped electrode 42 can also be 15KV or 20KV, etc. This invention does not specifically limit the voltage of the DC power supplied by the high-voltage transformer to the first needle-shaped electrode 42.
[0041] It should be noted that the power supply component of this utility model is not limited to the high-voltage transformer mentioned above. Those skilled in the art can also use other types of power supply components in practical applications.
[0042] Preferably, such as Figures 2 to 4 As shown, the plurality of first needle-shaped electrodes 42 are divided into multiple groups of electrodes. Each group of electrodes includes a plurality of first needle-shaped electrodes 42 spaced apart along a first direction. The multiple groups of electrodes are spaced apart along a second direction, and the first direction is perpendicular to the second direction.
[0043] For example, the first direction is the horizontal direction, which is the X direction in the figure, and the second direction is the vertical direction, which is the Z direction in the figure. The multiple first needle-shaped electrodes 42 are divided into 3 electrode groups, and the 3 electrode groups are distributed at intervals along the Z direction. Each group of electrodes includes multiple first needle-shaped electrodes 42 distributed at intervals along the X direction. This is equivalent to distributing multiple first needle-shaped electrodes 42 in a vertical plane. In this way, the coverage area of the multiple first needle-shaped electrodes 42 can be further increased, and they can make more sufficient contact with the airflow, thereby increasing the number of negative ions generated.
[0044] Preferably, the plane containing the plurality of first needle electrodes 42 is perpendicular to the flow direction of the airflow in the drying duct 2.
[0045] By aligning the plane containing the multiple first needle electrodes 42 perpendicular to the flow direction of the airflow in the drying duct 2, the airflow can make more thorough contact with the multiple first needle electrodes 42, thereby ionizing and generating more negative ions.
[0046] For example, the drying duct 2 is horizontally arranged below the drying cylinder 1, and the airflow in the drying duct 2 flows horizontally. In this case, it is preferable that the plane containing the plurality of first needle-shaped electrodes 42 is arranged vertically. Figure 2 Viewed from the center, the airflow flows along the Y direction, and the plane where the multiple first needle-shaped electrodes 42 are located is a vertical plane formed by the X and Z directions, with the Y direction perpendicular to this vertical plane.
[0047] Preferably, such as Figures 2 to 4 As shown, the first needle-shaped electrode 42 of this utility model extends toward the evaporator 31 (i.e., the dehumidification component) along a third direction, and the third direction is perpendicular to both the first and second directions.
[0048] For example, from Figure 2 Looking at the top, with the third direction being the Y direction, the first needle electrode 42 extends towards the evaporator 31 along the Y direction, that is, the first needle electrode 42 extends in the direction of airflow.
[0049] Preferably, such as Figures 2 to 4 As shown, the electrode assembly 4 of this utility model also includes a plurality of second needle-shaped electrodes 43 spaced apart and mounted on the fixing member 41. The power supply member is also connected to the second needle-shaped electrodes 43 and can supply power to the second needle-shaped electrodes 43. The second needle-shaped electrodes 43 can also ionize air to generate negative ions. The extension direction of the second needle-shaped electrodes 43 intersects with the extension direction of the first needle-shaped electrodes 42.
[0050] By setting multiple spaced second needle-shaped electrodes 43 on the fixed component 41, both the first needle-shaped electrode 42 and the second needle-shaped electrode 43 can ionize the air to generate negative ions. Furthermore, the first needle-shaped electrode 42 and the second needle-shaped electrode 43 are set at an angle, which is beneficial for the electrode assembly 4 to ionize and generate more negative ions.
[0051] For example, the first needle electrode 42 extends along the Y direction and the second needle electrode 43 extends along the Z direction. That is, the extension direction of the second needle electrode 43 is perpendicular to the extension direction of the first needle electrode 42, and the angle between them is exactly 90 degrees.
[0052] Preferably, the distance between two adjacent first needle electrodes 42 is L, where 10mm ≤ L ≤ 35mm.
[0053] from Figure 2 Looking at the top, L is the distance between two adjacent first needle electrodes 42 along the X direction. By making the distance L between two adjacent first needle electrodes 42 between 10mm and 35mm, the negative ion generation efficiency can be better, which is more conducive to improving the dehumidification efficiency.
[0054] Specifically, by limiting the distance L between two adjacent first needle electrodes 42 to a range of 10mm to 35mm, the electric field distribution becomes denser and the electric field strength becomes relatively high. This helps to enhance the efficiency of negative ion generation, produce more negative ions, and thus more effectively remove moisture from humid air.
[0055] It should be noted that in other embodiments, the distance L between two adjacent first needle electrodes 42 can also be adjusted according to specific application scenarios and requirements, such as 8mm, 9mm, 40mm, etc. Of course, this utility model preferably limits the distance L between two adjacent first needle electrodes 42 to 10mm to 35mm.
[0056] Preferably, such as Figures 2 to 4 As shown, the length of the first needle electrode 42 is no more than 30 mm.
[0057] Preferably, such as Figure 2 As shown, the distance between the first needle electrode 42 and the evaporator 31 is D, where 10mm≤D≤35mm.
[0058] from Figure 2Looking at it from above, D is the distance between the tip of the first needle electrode 42 and the evaporator 31 along the Y direction. The Y direction is perpendicular to the X direction. When placed in the drying air duct, the airflow flows along the Y direction. By limiting the distance between the first needle electrode 42 and the evaporator 31 to between 10mm and 35mm, it is possible to avoid the airflow being obstructed or causing unnecessary interference due to the distance between the first needle electrode 42 and the evaporator 31 being too small. It is also possible to avoid the influence of negative ions being weakened due to the distance between the first needle electrode 42 and the evaporator 31 being too large.
[0059] It should be noted that in other embodiments, the distance D between the first needle electrode 42 and the evaporator 31 can be adjusted according to specific application scenarios and performance requirements, such as 8mm, 9mm, 40mm, or 42mm. Of course, this invention preferably limits the distance D between the first needle electrode 42 and the evaporator 31 to the range of 10mm to 35mm.
[0060] Preferably, the ratio of the distance L between two adjacent first needle electrodes 42 to the distance D between the first needle electrode 42 and the evaporator 31 is not greater than 2, that is, L / D≤2.
[0061] Preferably, such as Figures 2 to 4 As shown, the electrode assembly 4 of this utility model includes a first fixing member 411 and a second fixing member 412 detachably mounted on the first fixing member 411. The first fixing member 411 is connected to the evaporator 31 (i.e., the dehumidification member), and the second fixing member 412 is spaced apart from the evaporator 31. The first needle electrode 42 is mounted on the second fixing member 412.
[0062] The first fixing member 411 and the second fixing member 412 can be connected by fasteners such as snap-fit, plug-in or screw, so as to facilitate the removal of the second fixing member 412 and the first needle electrode 42 on the second fixing member 412 from the first fixing member 411 for maintenance, etc.
[0063] It should be noted that this utility model does not limit the specific structural form of the first fixing member 411. For example, the first fixing member 411 can be set as a fixing frame, fixing plate or fixing block, etc. In addition, this utility model does not limit the second fixing member 412. For example, the second fixing member 412 can be set as a fixing frame or fixing plate, etc. Such adjustments and changes to the specific structural forms of the first fixing member 411 and the second fixing member 412 do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.
[0064] Preferably, such as Figure 2 and Figure 3As shown, the first fixing member 411 of this utility model includes a first fixing plate 4111 and a second fixing plate 4112 arranged opposite to each other. The first fixing plate 4111 is provided with a first insertion groove 41111 on the side facing the second fixing plate 4112, and the second fixing plate 4112 is provided with a second insertion groove 41121 on the side facing the first fixing plate 4111. The two edges of the second fixing member 412 are respectively inserted into the first insertion groove 41111 and the second insertion groove 41121.
[0065] For example, both the first fixing plate 4111 and the second fixing plate 4112 are vertically arranged, and are positioned opposite each other along the X direction. The second fixing member 412 is located between the first fixing plate 4111 and the second fixing plate 4112. The first needle-shaped electrode 42 and the second needle-shaped electrode 43 are both mounted on the second fixing member 412. One end of the first fixing plate 4111 along the Y direction (the Y direction is perpendicular to the X direction) is connected to one end of the evaporator 31. A first insertion groove 41111 is provided near the other end of the first fixing plate 4111. The first insertion groove 41111 extends vertically. The top is open. One end of the second fixing plate 4112 along the Y direction is connected to the other end of the evaporator 31. A second insertion groove 41121 is provided near the other end of the second fixing plate 4112. The second insertion groove 41121 extends vertically. The first insertion groove 41111 and the second insertion groove 41121 are arranged opposite each other along the X direction. The thickness of the left and right edges of the second fixing member 412 is equal to or slightly less than the width of the first insertion groove 41111 and the second insertion groove 41121. The left edge of the second fixing member 412 is inserted into the first insertion groove 41111, and the right edge of the second fixing member 412 is inserted into the second insertion groove 41121.
[0066] Preferably, such as Figure 3 and Figure 4 As shown, the second fixing member 412 is a rectangular frame.
[0067] For example, the rectangular frame has three strip plates spaced apart along the Z direction, each strip plate extending along the X direction, and each strip plate is provided with a plurality of first needle-shaped electrodes 42 spaced apart along the X direction and a plurality of second needle-shaped electrodes 43 spaced apart along the X direction.

[0069] Filter 5 can filter impurities such as lint carried by the airflow.
