Description

[0002] Electrolytic capacitors, as key components on the control board of washing machine inverters, have a shorter lifespan compared to other electronic components. Temperature is a significant factor affecting their lifespan. The positive electrode of an electrolytic capacitor is anodized aluminum foil, while the negative electrode is composed of an electrolyte. Higher temperatures cause the electrolyte to evaporate faster, increasing the equivalent series resistance and decreasing the static capacitance. This creates a vicious cycle, accelerating electrolyte evaporation and increasing internal pressure, leading to leakage and ultimately permanent damage or complete electrolyte depletion and capacitor malfunction.

[0003] To prevent electrolytic capacitors from overheating during operation, which could lead to damage or malfunction, and to slow down their aging process, the temperature of the electrolytic capacitors should be kept as low as possible to extend their lifespan. Summary of the Invention

[0045] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0047] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0048] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0049] In existing washing machines, the higher the temperature of the electrolytic capacitor, the faster its electrolyte evaporates, which leads to a larger equivalent series resistance and a smaller static capacitance value, thus creating a vicious cycle. This causes the electrolyte to evaporate faster and faster, accompanied by an increase in internal pressure, resulting in electrolyte leakage and ultimately permanent damage or malfunction of the electrolytic capacitor.

[0050] This invention creatively provides a clothing processing device, including a clothing processing tank, a water pipe, and a control device; the water pipe is connected to the clothing processing tank, and a receiving cavity is formed on the outside of the water pipe, which is separated from the inside of the water pipe; the control device includes a frequency converter control board and an electrolytic capacitor disposed on the frequency converter control board; the electrolytic capacitor is disposed in the receiving cavity, and the electrolytic capacitor and the water in the water pipe have a heat exchange relationship; when the water flows through the water pipe, the water and the electrolytic capacitor exchange heat, efficiently removing the heat from the electrolytic capacitor.

[0051] Example 1

[0052] like Figure 1 As shown, this embodiment proposes a garment processing device, including:

[0053] Clothing processing bin

[0054] Water pipe 1 is connected to the laundry processing bucket; a receiving cavity 124 is formed on the outside of the water pipe 1, and the receiving cavity 124 and the interior of the water pipe 1 are separated from each other and are not connected.

[0055] The control device includes a frequency converter control board 21 and an electrolytic capacitor 22; the electrolytic capacitor 22 is disposed on the frequency converter control board 21 and disposed within the receiving cavity 124.

[0056] The water in the water pipe and the electrolytic capacitor 22 have a heat exchange relationship. The water in the water pipe 1 and the electrolytic capacitor 22 exchange heat through the pipe wall of the water pipe 1 to cool the electrolytic capacitor 22.

[0057] When water flows through water pipe 1, the water and the electrolytic capacitor exchange heat, efficiently carrying away the heat from the electrolytic capacitor, reducing its temperature, slowing down its aging process, and extending its service life.

[0058] Specifically, the water pipe 1 includes a main pipe section 11 and a cooling pipe section 12. The main pipe section 11 is connected to the clothes handling tank, and the cooling pipe section 12 is located on the main pipe section 11 and outside the main pipe section 11. A cooling tank 123 is formed inside the cooling pipe section 12, and the cooling tank 123 is connected to the inside of the main pipe section 11 for storing and flowing water. A receiving cavity 124 is formed outside the cooling pipe section 12, and the receiving cavity 124 and the cooling tank 123 are separated from each other and are not connected.

[0059] The water in the cooling tank 123 and the electrolytic capacitor 22 in the receiving cavity 124 exchange heat through the pipe wall of the cooling pipe section 12.

[0060] Preferably, the cooling pipe section 12 is detachably installed on the main pipe section 11. Cooling pipe sections 12 with different structures can be installed on the main pipe section 11. The volume of the cooling tank 123 corresponding to the different structures of the cooling pipe sections 12 is different. Cooling pipe sections 12 with corresponding structures can be installed according to cooling needs.

[0061] The following further explains the structural compatibility between the receiving cavity 124 and the electrolytic capacitor 22. The structure of the receiving cavity 124 is designed to be compatible with the structure of the electrolytic capacitor 22, thereby increasing the heat exchange area between the receiving cavity 124 and the electrolytic capacitor 22, further improving the heat exchange efficiency between water and the electrolytic capacitor 22, and increasing the cooling rate of the electrolytic capacitor 22.

[0062] Furthermore, multiple receiving cavities 124 are provided; the multiple receiving cavities 124 have different structures, and the different structures of the receiving cavities 124 can be adapted to the corresponding structures of the electrolytic capacitors 22; specifically, the differences in the structures of the multiple receiving cavities 124 include different structural shapes and / or different structural dimensions; by adapting the structure of the receiving cavity 124 to the structure of the electrolytic capacitor 22, the cooling efficiency is improved; and / or,

[0063] The multiple receiving cavities 124 are located in different positions. Depending on the installation space or disassembly requirements, the electrolytic capacitor 22 can be installed in the receiving cavity 124 at the corresponding position. Specifically, the different positions of the multiple receiving cavities 124 include the different positions of the receiving cavity 124 relative to the cooling tank 123 and / or the different positions of the receiving cavity 124 relative to the main pipe section 11 and / or the different positions of the receiving cavity 124 relative to the electrolytic capacitor 22 and / or the different positions of the receiving cavity 124 relative to the clothing processing tub and / or the different positions of the receiving cavity 124 relative to other components of the clothing processing equipment (such as the housing).

[0064] By adapting the location and space of the receiving cavity 124 to the needs of assembly and disassembly, the location of the receiving cavity 124 satisfies both the cooling requirements and the space requirements for assembly and disassembly, thereby improving cooling efficiency.

[0065] The specific structure of the cooling pipe section 12 is further described below. The pipe wall of the cooling pipe section 12 includes an annular pipe wall 121 and an end pipe wall 122. One end of the annular pipe wall 121 is provided on the pipe wall of the main pipe section 11, and the other end of the annular pipe wall 121 is provided with an end pipe wall 122.

[0066] The annular pipe wall 121 and the end pipe wall 122 together form a cooling tank 123. The end pipe wall 122 is recessed into the interior of the cooling pipe section 12 to form a receiving cavity 124. Water inside the main pipe section 11 can enter the interior of the cooling pipe section 12 and then enter the cooling tank 123 to exchange heat with the electrolytic capacitor in the receiving cavity 124.

[0067] Furthermore, the cooling tank 123 extends outward along the radial direction of the main pipe section 11 or is arranged around the main pipe section 11; the receiving cavity 124 extends inward along the radial direction of the main pipe section 11 or the extension direction of the receiving cavity 124 is parallel to the extension direction of the main pipe section 11.

[0068] Preferably, the cooling tank 123 extends radially outward along the main pipe section 11, and the receiving cavity 124 extends radially inward along the main pipe section 11.

[0069] The following describes the structure required for timely drainage of water from the cooling tank 123. A water valve is connected in series on the main pipe section 11, and the water valve is located downstream of the cooling pipe section 12. When the water valve is in the open state, the water in the cooling tank 123 can be drained in time. When the water valve is in the closed state, the water in the cooling tank 123 can be retained.

[0070] The garment processing equipment also includes a first temperature sensor 3, a second temperature sensor, and a controller. The first temperature sensor 3 is installed in the cooling tank 123 and is used to detect the temperature of the water in the cooling tank 123. The second temperature sensor is used to detect the external temperature of the electrolytic capacitor 22. The controller is communicatively connected to the first temperature sensor 3, the second temperature sensor, and the water valve. The controller is used to receive the detection data transmitted by the first temperature sensor 3 and / or the second temperature sensor.

[0071] The controller is configured to: control the water valve to open or close the main pipe section 11 or adjust the valve opening size when the water valve is in the open state, based on the temperature of the water in the cooling tank 123 and / or the external temperature of the electrolytic capacitor 22; when the water valve is in the open state, the water in the cooling tank 123 can be drained in time to avoid the problem of slow cooling speed of the electrolytic capacitor 22 caused by the retention of high temperature water in the cooling tank 123.

[0072] Preferably, water pipe 1 is a drain pipe, and water valve is a drain valve; the clothing processing tank is provided with a drain outlet, one end of the drain pipe is connected to the drain outlet, and the other end is connected to the external environment, for draining water from the clothing processing tank; the clothing processing tank can supply water to the main pipe section 11 through the drain outlet, and then the water can enter the cooling tank 123 through the cooling pipe section 12; the controller is electrically connected to the first temperature sensor 3, the second temperature sensor, and the water valve respectively; wherein, the external environment is the environment in which the clothing processing equipment is located;

[0073] When water is stored or flows through the cooling tank 123, the water in the cooling tank 123 has a heat exchange relationship with the electrolytic capacitor 22; making full use of the water discharged from the clothing processing bucket to cool the electrolytic capacitor 22 saves water and reduces energy consumption, while also reducing the impact on the existing structure of the clothing processing equipment.

[0074] The heat dissipated by the electrolytic capacitor 22 is transferred to the water in the drain pipe. The water is then drained out, carrying away the heat dissipated by the electrolytic capacitor 22. Because water has a high specific heat capacity, it can absorb more heat in a given volume, making it suitable as a cooling medium for dissipating heat from the electrolytic capacitor 22. Simultaneously, the garment processing equipment itself has a sufficient water source for easy replenishment. When the water absorbs the heat dissipated by the electrolytic capacitor 22, its temperature rises to a certain level. Draining the water and replacing it with cooler water continuously cools the electrolytic capacitor 22. This effectively reduces the temperature of the electrolytic capacitor 22, slows down the evaporation rate of the electrolyte, extends its lifespan, reduces the likelihood of after-sales repairs, improves user experience, and saves costs.

[0075] The following is a further explanation of the structure required to timely supply water to the laundry processing tank. The laundry processing equipment also includes a water inlet pipe. The laundry processing tank is also equipped with a water inlet. One end of the water inlet pipe is connected to the water inlet, and the other end is connected to an external water source. The water inlet pipe is used to input water into the laundry processing tank. A water inlet valve is connected in series on the water inlet pipe.

[0076] The controller is also configured to: control the water inlet valve to open or close the water inlet pipe, or adjust the valve opening size of the water inlet valve when the water inlet valve is in the open state, based on the operating status of the garment processing equipment and the temperature of the water in the cooling tank 123.

[0077] like Figure 2 As shown, this embodiment also proposes a control method for a garment processing device, wherein the garment processing device is the garment processing device described above; the control method includes:

[0078] S1. When the clothing processing equipment starts running, water is supplied to the cooling tank 123 until the volume of water in the cooling tank 123 is greater than the preset volume; so that the volume of water in the cooling tank 123 is sufficient.

[0079] S2. During the operation of the clothing processing equipment, the temperature of the water in the cooling tank 123 is obtained;

[0080] S3. Based on the temperature of the water in the cooling tank 123, retain or update the water in the cooling tank 123 to ensure that the temperature of the water in the cooling tank 123 meets the cooling requirements.

[0081] Furthermore, S3 includes:

[0082] Compare the water temperature in cooling tank 123 with the preset minimum temperature and preset maximum temperature respectively;

[0083] When the temperature of the water in the cooling tank 123 is less than or equal to the preset minimum temperature, the water in the cooling tank 123 is retained; when the temperature of the water in the cooling tank 123 meets the cooling requirements, it can also be used to cool the electrolytic capacitor 22.

[0084] When the temperature of the water in the cooling tank 123 is greater than or equal to the preset maximum temperature, the water in the cooling tank 123 is drained and water is replenished to the cooling tank 123 to refresh the water in the cooling tank in a timely manner. This allows the high-temperature water in the cooling tank 123 to be drained and the low-temperature water to be replenished, so that the temperature of the water in the cooling tank 123 can meet the cooling requirements.

[0085] The following describes the structures required for supplying water to the cooling tank 123, draining water from the cooling tank 123, and retaining water in the cooling tank;

[0086] The process of supplying water into the cooling tank 123 includes: allowing water to enter the cooling tank 123 via the main pipe section 11;

[0087] The water retention in the cooling tank 123 includes: controlling the water valve to close the main water pipe section 11;

[0088] Discharging water from the cooling tank 123 includes: controlling the water valve to open the main pipe section 11, so that the water in the cooling tank 123 is discharged through the main pipe section 11;

[0089] The following example uses a water pipe as a drain pipe and a water valve as a drain valve to further illustrate the point.

[0090] The process of supplying water to the cooling tank 123 includes: allowing water from the laundry tub to enter the cooling tank 123 through the main drain pipe section 11;

[0091] The water retained in the cooling tank 123 includes: the main drain pipe section 11 that controls the drain valve to close;

[0092] Discharging water from the cooling tank 123 includes: controlling the drain valve to open the main drain pipe section 11, so that the water in the cooling tank 123 is discharged through the main drain pipe section 11;

[0093] Since the main drain pipe section 11 is connected to the drain outlet of the clothes handling tub, and there is no valve between the connection point between the inside of the main drain pipe section 11 and the inside of the cooling pipe section and the drain outlet, as long as the drain valve is opened, the water in the main drain pipe section 11 flows, and the water in the cooling tank 123 can be discharged. At the same time, the water in the clothes handling tub can enter the cooling tank 123 through the main drain pipe section 11, thus refreshing the water in the cooling tank 123. As long as the drain valve is closed, the water in the main drain pipe section 11 does not flow, and the water in the clothes handling tub cannot enter the cooling tank 123, thus retaining the water in the cooling tank 123.

[0094] Specifically, such as Figure 3 As shown, when the garment processing equipment is detected to be running, the controller sends a command to open the inlet valve and close the drain valve. External water enters the garment processing tank through the inlet pipe and inlet. Water from inside the garment processing tank enters the main drain pipe section 11 through the drain outlet, and then enters the cooling tank 123 through the cooling pipe section 12, thus filling the cooling tank 123. When the garment processing equipment is running, as... Figure 4 As shown, taking AC mains power as an example, 220V AC power is rectified into 310V DC power by a rectifier bridge. The electrolytic capacitor 22 connected in parallel on the DC side absorbs high-amplitude pulsating current and stabilizes DC voltage. Due to ripple current in the circuit, the electrolytic capacitor 22 heats up and its internal temperature rises. The water in the cooling tank 123 can absorb the heat dissipated by the electrolytic capacitor 22 and cool it down.

[0095] A first temperature sensor 3 is installed in the cooling tank 123. The first temperature sensor 3 detects the temperature Tc of the water in the cooling tank 123 in real time and transmits it to the controller. As the temperature of the electrolytic capacitor 22 gradually rises, the water in the cooling tank 123 absorbs the heat dissipated by the electrolytic capacitor 22, causing the water temperature to gradually rise.

[0096] Determine whether the water temperature Tc in the cooling tank 123 is greater than the preset maximum temperature Tch and whether the water temperature Tc in the cooling tank 123 is lower than the preset minimum temperature Tcl.

[0097] When the temperature Tc of the water in the cooling tank 123 is detected to be greater than the preset maximum temperature Tch (the preset maximum temperature Tch can be 1.2 times the rated operating temperature of the electrolytic capacitor 22), the drain valve is opened to flush away the high-temperature water in the cooling tank 123. The discharge of water from the cooling tank 123 also carries away the heat dissipated by the electrolytic capacitor 22; the clothes processing tub then supplies water back into the cooling tank 123, allowing the cooling tank 123 to be refreshed with lower-temperature water.

[0098] When the temperature Tc of the water in the cooling tank 123 is detected to be lower than the preset minimum temperature Tcl (the preset minimum temperature Tcl can be 0.8 times the rated operating temperature of the electrolytic capacitor 22), the drain valve is closed so that the low-temperature water in the cooling tank 123 continues to cool the electrolytic capacitor 22.

[0099] In this method, the water in the cooling tank 123 can absorb and carry away the heat emitted by the electrolytic capacitor 22; effectively reducing the temperature of the electrolytic capacitor 22, slowing down the evaporation rate of the electrolyte in the electrolytic capacitor 22, extending the service life of the electrolytic capacitor 22, thereby reducing the probability of after-sales maintenance, improving the user experience and saving costs.

[0100] Example 2

[0101] Based on Example 1, this example proposes that the garment processing equipment further includes a rotating shaft and an impeller, with the impeller and rotating shaft connected in a driving connection;

[0102] A portion of the rotating shaft and a portion of the impeller are rotatably disposed within the main pipe section 11, and another portion of the rotating shaft and another portion of the impeller are rotatably disposed within the cooling tank 123; or,

[0103] The rotating shaft includes a first shaft section and a second shaft section; the first shaft section is rotatably disposed within the main shaft section 11, and the second shaft section is connected to the first shaft section and rotatably disposed within the cooling tank 123; the impeller includes a main impeller and a driven impeller, the main impeller is drivenly connected to the first shaft section, and the driven impeller is drivenly connected to the second shaft section;

[0104] Under the action of water flowing through the main pipe section 11, the shaft and impeller rotate. The rotation of the impeller can carry the water in the cooling tank 123, improve the heat exchange efficiency between the water in the cooling tank 123 and the electrolytic capacitor 22, and further improve the cooling speed of the electrolytic capacitor 22.
